AB  - Systemic sclerosis (SSc) is a rare connective tissue disorder with highest morbidity and mortality among rheumatologic diseases. Disease progression is highly heterogeneous between patients, implying a strong need for individualization of therapy. Four pharmacogenetic variants, namely TPMT rs1800460, TPMT rs1142345, MTHFR rs1801133 and SLCO1B1 rs4149056 were tested for association with severe disease outcomes in 102 patients with SSc from Serbia treated either with immunosuppressants azathioprine (AZA) and methotrexate (MTX) or with other types of medications. Genotyping was performed using PCR-RFLP and direct Sanger sequencing. R software was used for statistical analysis and development of polygenic risk score (PRS) model. Association was found between MTHFR rs1801133 and higher risk for elevated systolic pressure in all patients except those prescribed with MTX, and higher risk for kidney insufficiency in patients prescribed with other types of drugs. In patients treated with MTX, variant SLCO1B1 rs4149056 was protective against kidney insufficiency. For patients receiving MTX a trend was shown for having a higher PRS rank and elevated systolic pressure. Our results open a door wide for more extensive research on pharmacogenomics markers in patients with SSc. Altogether, pharmacogenomics markers could predict the outcome of patients with SSc and help in prevention of adverse drug reactions.

AB  - Host genetics, an important contributor to the COVID-19 clinical susceptibility and severity,
currently is the focus of multiple genome-wide association studies (GWAS) in populations
affected by the pandemic. This is the first study from Serbia that performed a GWAS of
COVID-19 outcomes to identify genetic risk markers of disease severity. A group of 128
hospitalized COVID-19 patients from the Serbian population was enrolled in the study.
We conducted a GWAS comparing (1) patients with pneumonia (n = 80) against patients
without pneumonia (n = 48), and (2) severe (n = 34) against mild disease (n = 48) patients,
using a genotyping array followed by imputation of missing genotypes. We have detected
a significant signal associated with COVID-19 related pneumonia at locus 13q21.33, with
a peak residing upstream of the gene KLHL1 (p = 1.91 × 10−8). Our study also replicated
a previously reported COVID-19 risk locus at 3p21.31, identifying lead variants in SACM1L
and LZTFL1 genes suggestively associated with pneumonia (p = 7.54 × 10−6) and
severe COVID-19 (p = 6.88 × 10−7), respectively. Suggestive association with COVID-19
pneumonia has also been observed at chromosomes 5p15.33 (IRX, NDUFS6,MRPL36, p
= 2.81 × 10−6), 5q11.2 (ESM1, p = 6.59 × 10−6), and 9p23 (TYRP1,LURAP1L, p = 8.69 ×
10−6). The genes located in or near the risk loci are expressed in neural or lung tissues, and
have been previously associated with respiratory diseases such as asthma and COVID-19
or reported as differentially expressed in COVID-19 gene expression profiling studies.
Our results revealed novel risk loci for pneumonia and severe COVID-19 disease which
could contribute to a better understanding of the COVID-19 host genetics in different
populations.

AB  - Introduction: The NUDT15 is new pharmacogene of importance for 6-mercaptopurine therapy, given to
children with acute lymphoblastic leukemia (ALL). The association ofside effectsin children with variants
in NUDT15 are well established in Asian populations, yet the relevance ofthis pharmacogene in European
populationsremainslargely unexplored. The aim of thisstudy wasto identify pharmacogenetic variants
in coding and neighbouring regions of NUDT15 gene and analyse if the expression levels of NUDT15 can
predict the occurence of side effects of 6-mercaptopurine during the maintenance therapy in children
with ALL of Serbian origin.
Methods: The genotyping of coding and neighbouring regions of NUDT15 gene was performed using
PCR and Sangersequencing based technology in 48 children with ALL. NUDT15 expression was analyzed
in mononuclear cells of 24 ALL patients at diagnosis and 6 healthy controls by qRT-PCR, and association
with surogate markers was assessed using adequate statistical methodology.
Results: The genotypig revealed the presence of 5 variantsin NUDT15 (NUDT15(NM_018283.4):c.36A>C,
NUDT15(NM_018283.4):c.158+117C>T,NUDT15(NM_018283.4):c.158+174G>A,NUDT15(NM_018283.4):c.159-
91G>A,NUDT15(NM_018283.4):c.*7G>A), none of them with effects on the expression or the function of
NUDT15 protein. There was no statistically significant association between the expression of NUDT15 at
diagnosis and the surogate markers of side effects (number of episodes of leukopenia (p=0.821), number of weeks without therapy (p=0.507), number of weeks with lower dose (p=0.434), average doses
(p=0.374)) of 6-mercaptopurine during the maintenance therapy.
Conclusion: Presently, NUDT15 cannot be used as a pharmacogene in predicting the toxicity of 6-mercaptopurine terapy in children with ALL in Serbia.

Recent findings  AQ5 In patients infected with SARS-CoV-2 virus, altered circulating levels of micronutrients may serve as prognostic markers of disease severity.

AB  - Acute lymphoblastic leukemia (ALL) is the most common childhood neoplasm. Side
effects of therapy occur in 75% of patients and 1-3% of patients have a lethal outcome due
to treatment. More efficient treatment of pediatric ALL has been developed by avoiding
drug adverse effects included in the treatment protocols. Therefore, implementation of
pharmacogenomics is paramount in pediatric ALL treatment. Next generation sequencing
(NGS) contributed to discovery of novel genetic markers, potential candidates for targeted
therapy and predictors of efficacy and toxicity of drugs.
We aimed to discover novel potential pharmacogenomic markers in pediatric ALL.
DNA samples from bone marrow of 17 pediatric ALL patients were analyzed using
the platform TruSeq Amplicon – Cancer Panel (Ilumina) for somatic mutations in 48
oncogenes. DNA samples from blood of 100 individuals, using the platform TruSightOne
(Ilumina), were analyzed for germinative mutations. An in-house virtual panel for GC
response markers was designed. Predicting the effects of novel variants was performed
using the SIFT, PolyPhen-2 and PROVEAN software tools. For protein structure stability
and modeling we used STRUM method and i-TASSER server.
In the NGS study of somatic mutations in pediatric ALL, 9 novel variants have been
identified. Bioinformatic analysis has shown that STK11 c.1023G>T and ERBB2 c.2341C>T
possess potential as pharmacogenomic markers, therefore, they are candidates for
molecular targeted therapy. In the exome sequencing study, according to the prediction
algorithms, 3 new potential markers in pharmacogenes related to GC response have been
identified, ABCB1 c.947A>G, NCOA3 rs138733364 and TBX21 rs14059812.
Using NGS analysis and prediction algorithms, we have detected 2 novel somatic mutations,
candidates for targeted molecular therapy, as well as 3 novel germinative variants,
potential pharmacogenomic markers of GC response in pediatric ALL. Pharmacogenomic
profiling of each pediatric ALL patient is indispensable for new therapy approaches and it
could lead to better outcomes.

abstract = "Acute lymphoblastic leukemia (ALL) is the most common childhood neoplasm. Side
effects of therapy occur in 75% of patients and 1-3% of patients have a lethal outcome due
to treatment. More efficient treatment of pediatric ALL has been developed by avoiding
drug adverse effects included in the treatment protocols. Therefore, implementation of
pharmacogenomics is paramount in pediatric ALL treatment. Next generation sequencing
(NGS) contributed to discovery of novel genetic markers, potential candidates for targeted
therapy and predictors of efficacy and toxicity of drugs.

AB  - COVID-19 pandemic has proved to be an unrelenting health threat for more than a year now. The
emerging amount of data indicates that vitamin D could be important for clinical presentation of
COVID-19. Here, we investigated association of genetic variants related to the altered level and
bioavailability of vitamin D with clinical severity of COVID-19. We analyzed variants in genes
significant for the status of vitamin D (DHCR7/NADSYN1 rs12785878, GC rs2282679, and CYP2R1
rs10741657), and vitamin D effect (VDR rs2228570) in 120 Serbian adult and pediatric COVID-19
patients using allelic discrimination. Furthermore, we carried out comparative population genetic
analysis among European and other worldwide populations to investigate variation in allelic
frequencies of selected variants. The results showed that DHCR7/NADSYN rs12785878 and CYP2R1
rs10741657 variants were associated with severe COVID-19 in adults (p = 0.03, p = 0.017,
respectively); carriers of DHCR7/NADSYN TG+GG and CYP2R1 GG genotypes had 0.21 and 5.9 the
odds for developing severe disease, OR 0.21 (0.05–0.9) and OR 5.9 (1.4–25.2), respectively. There
were no associations between selected genetic variants and disease severity in pediatric patients.
Comparative population genetic analysis revealed that Serbian population had the lowest frequency of
CYP2R1 rs10741657 G allele compared to other non-Finish Europeans (0.58 compared to 0.69 and
0.66 in Spanish and Italian population, respectively), suggesting that other populations should also
investigate the relationship of CYP2R1 variant and the COVID-19 disease course. The results of the
study indicated that vitamin D related genetic variants were implicated in severe COVID-19 in adults.
This could direct prevention strategies based on population specific nutrigenetic profiles.

AB  - Introduction: Systemic sclerosis(SSc) is a rare autoimmune disorder that affects connective tissues and
hasthe highest morbidity and mortality among rheumatologic diseases. Clinical presentations as well as
disease progression are highly heterogeneous between patients, implying a strong need for individualization of therapy.
Methods: Four pharmacogenetic variants, namely TPMT rs1800460, TPMT rs1142345, MTHFR rs1801133
and SLCO1B1 rs4149056 were tested for association with severe disease outcomes in 102 patients with
SSc from Serbia treated either with immunosuppressants azathioprine (AZA) and methotrexate (MTX) or
with other types of medications. Genotyping was performed using PCR-RFLP and direct Sanger sequencing. R software was used for statistical analysis and development of polygenic risk score (PRS)
model.
Results: Association wasfound between MTHFR rs1801133 and higher risk for elevated systolic pressure
in all patients except those prescribed with MTX, and higher risk for kidney insufficiency in patients prescribed with other types of drugs. In patients treated with MTX, variant SLCO1B1 rs4149056 was protective against kidney insufficiency. For patients receiving MTX a trend was shown for having a higher PRS
rank and elevated systolic pressure.
Conclusion: Our results open a door wide for more extensive research on pharmacogenomics markers
in patients with SSc. Altogether, pharmacogenomics markers could predict the outcome of patients with
SSc and help in prevention of adverse drug reactions

AB  - Vincristine (VCR) is one of the key drugs in current treatment protocols for pediatric acute
lymphoblastic leukemia (ALL). By destabilization of microtubules, VCR arrests cells in metaphase,
inducing apoptosis of malignant cells. VCR also causes axonal degradation and impairment of axonal
transport, which leads to vincristine-induced peripheral neuropathy (VIPN). The aim of this study was
to determine if the selected genetic variants are associated with the development of VIPN in ALL
children treated with VCR in Serbia. This study also aimed to discover candidate pharmacogenomic
markers of VIPN in Serbian population. PCR and sequencing-based methodology was used to detect
variants in following genes: CYP3А5 (rs776746), CEP72 (rs924607), ACTG1 (rs1135989), MIR3117
(rs12402181) and MIR4481 (rs7896283). Statistical analyses were performed for investigation of their
association with VIPN in 56 pediatric ALL patients. Population VCR pharmacogenomics analysis of 17
pharmacogenes from in-house next-generation sequencing data was also done. Data on allele frequency
distribution for European population were extracted from public databases. During the treatment,
17.86% of patients developed VIPN. Association analyses have shown that none of the investigated
genetic variants contributed to the occurrence of VIPN in our study group. Population
pharmacogenomics study didn’t reveal valid candidate pharmacovariants for the occurrence of VIPN.
Our results suggested that pre-emptive pharmacogenetic testing for VCR is not applicable. More
comprehensive approaches are needed to identify panel of genes that could explain the VIPN
development after VCR administration in ALL patients. Utilizing better designed GWAS studies and
more robust artificial intelligence-based tools would provide a panel of pharmacogenes for pre-emptive
tests of VIPN to individualize therapy for ALL in children.

AB  - Inflammatory bowel disease (IBD), Crohn’s disease (CD) and ulcerative colitis (UC) are complex diseases whose etiology is associated with genetic and environmental risk factors, among which are diet and gut microbiota. To date, IBD is an incurable disease and the main goal of its treatment is to reduce symptoms, prevent complications, and improve nutritional status and the quality of life. Patients with IBD usually suffer from nutritional deficiency with imbalances of specific micronutrient levels that contribute to the further deterioration of the disease. Therefore, along with medications usually used for IBD treatment, therapeutic strategies also include the supplementation of micronutrients such as vitamin D, folic acid, iron, and zinc. Micronutrient supplementation tailored according to individual needs could help patients to maintain overall health, avoid the triggering of symptoms, and support remission. The identification of individuals’ genotypes associated with the absorption, transport and metabolism of micronutrients can modify future clinical practice in IBD and enable individualized treatment. This review discusses the personalized approach with respect to genetics related to micronutrients commonly used in inflammatory bowel disease treatment.

AB  - Monoklonsko antitelo proizvedeno u mišu, označeno kao Y7, napravljeno je
protiv prirodnog IgM antitela, izolovanog iz osobe sa Valdenstromovom
makroglobulinemijom i specifičnog za jednolančanu DNK. Y7 antitelo je tom
prilikom detaljno okarakterisano i utvrđeno je da pripada podklasi IgG1 i da je
specifično za Fab region prirodnog IgM molekula, čime je antitelo Y7
okarakterisano kao anti-idiotipsko antitelo.1 Nedavno smo metodom protočne
citometrije otkrili da se Y7 antitelo vezuje za humane leukocite, konkretno za
granulocite i monocite. Vezivanje za granulocite i monocite različitih ljudi je
pokazalo individualne varijacije, te je pretpostavljeno da se radi o alel
specifičnoj interakciji, preko Fcγ receptora. Da bi se potvrdila ova
pretpostavka urađena je genotipizacija FcγR2A H166R polimorfizma, paralelno
sa analizom protočnom citometrijom (n = 20) u dve vremenske tačke. Vezivanje Y7
bilo je istovetno u dve vremenske tačke i u potpunosti se podudaralo sa

H166R, sa vezivanjem Y7 za R varijantu. Vezivanje je detektovano i kod
heterozigotnih i homozigotnih osoba, dok kod H homozigotnih osoba nije bilo
vezivanja. Specifičnost ka alelskoj varijanti je potvrđena Vestern blotom.
Inhibicija vezivanja testirana je pomoću C-reaktivnog proteina, ali nije bilo
moguće postići više od 20% inhibicije. Neke alelske varijante genetskih
polimorfizama, gde spada i rs1801274 (H166R) polimorfizam FCGR2A gena,
povezane su sa bržom progresijom zaraznih bolesti, a neke varijante se učestalije
javljaju u autoimunskim obolenjima. Dodatna istraživanja pokazaće da li se
interakcija Y7 za R varijantu može upotrebiti pri izvođenju funkcionalnih

AB  - Uvod/Cilj Vinkristin je jedan od ključnih lekova u protokolima lečenja dečje akutne limfoblastne leukemije (ALL). Vinkristin dovodi do destabilizacije mikrotubula, čime se ćelija zaustavlja u metafazi i indukuje apoptoza. Takođe dovodi do degradacije aksona i poremećaja aksonskog transporta, uzrokujući vinkristinom indukovanu perifernu neuropatiju (VIPN). Cilj ove studije bio je da istraži povezanost pet varijanti u farmakogenima uključenim u metabolizam vinkristina kod dece obolele od ALL koja su razvila VIPN, u Srbiji. Takođe, cilj nam je bio da otkrijemo kandidate za nove farmakogenomske markere VIPN-a u srpskoj populaciji.

Statističkim metodama je ispitana njihova asocijacija sa VIPN-om kod 56 pedijatrijskih bolesnika obolelih od ALL. Urađena je i populaciona vinkristin farmakogenomska analiza 17 farmakogena iz postojećih podataka dobijenih sekvenciranjem nove generacije u srpskoj populaciji. Podaci o distribuciji frekvencija alela za evropsko stanovništvo preuzeti su iz javnih baza podataka. Rezultati Tokom lečenja, 17,86% bolesnika je razvilo VIPN.

Naše populaciono farmakogenomsko istraživanje nije otkrilo validne farmakovarijante za VIPN. Naši rezultati ne preporučuju preventivno farmakogenetičko ispitivanje vinkristina u Srbiji. Zaključak Potreban je sveobuhvatniji pristup kako bi se identifikovao panel gena kojim bi se mogao objasniti razvoj VIPN-a posle primene vinkristina kod pedijatrijskih bolesnika obolelih od ALL. Bolje osmišljene studije asocijacija na nivou genoma (GWAS) i robusniji alati koji koriste veštačku inteligenciju doveli bi do dizajniranja panela farmakogena za preventivno testiranje predispozicije za razvoj VIPN-a, doprinoseći individualizaciji i unapređenju terapije dece obolele od ALL.
AB  - Introduction/Objective Vincristine (VCR) is one of the key drugs in current treatment protocols for pediatric acute lymphoblastic leukemia (ALL). By destabilizing microtubules, VCR arrests cells in metaphase, inducing apoptosis of malignant cells. VCR also causes axonal degradation and impairment of axonal transport, which leads to VCR-induced peripheral neuropathy (VIPN). This study aimed to investigate the association of five variants in pharmacogenes involved in VCR metabolism with VIPN in Serbian ALL children. We also wanted to discover candidate pharmacogenomic markers of VIPN in Serbian population. Methods PCR and sequencing-based methodology was used to detect variants in CYP3A5, CEP72, ACTG1, MIR3117, and MIR4481 genes. Statistical analyses were performed for investigating their association with VIPN in 56 pediatric ALL patients. Population VCR pharmacogenomics analysis of 17 pharmacogenes from in-house next-generation sequencing data was also done. Data on allele frequency distribution for the European population were extracted from public databases. Results During the treatment, 17.86% of patients developed VIPN. Association analyses have shown that none of the genetic variants contributed to the occurrence of VIPN in our study. Population pharmacogenomics study did not reveal valid candidate pharmacovariants for VIPN. Our results suggested that pre-emptive pharmacogenetic testing for VCR is not applicable presently. Conclusion More comprehensive approaches are needed to identify the panel of genes that could explain the VIPN development after VCR administration in ALL patients. Utilizing better designed genome-wide association studies and more robust artificial intelligence-based tools would provide a panel of pharmacogenes for pre-emptive tests of VIPN to individualize therapy for ALL in children.

AB  - Host genetics, an important contributor to the COVID-19 clinical susceptibility and severity, currently is the focus of multiple genome-wide association studies (GWAS) in populations affected by the pandemic. This is the first study from Serbia that performed a GWAS of COVID-19 outcomes to identify genetic risk markers of disease severity. A group of 128 hospitalized COVID-19 patients from the Serbian population was enrolled in the study. We conducted a GWAS comparing (1) patients with pneumonia (n = 80) against patients without pneumonia (n = 48), and (2) severe (n = 34) against mild disease (n = 48) patients, using a genotyping array followed by imputation of missing genotypes. We have detected a significant signal associated with COVID-19 related pneumonia at locus 13q21.33, with a peak residing upstream of the gene KLHL1 (p = 1.91 x 10(-8)). Our study also replicated a previously reported COVID-19 risk locus at 3p21.31, identifying lead variants in SACM1L and LZTFL1 genes suggestively associated with pneumonia (p = 7.54 x 10(-6)) and severe COVID-19 (p = 6.88 x 10(-7)), respectively. Suggestive association with COVID-19 pneumonia has also been observed at chromosomes 5p15.33 (IRX, NDUFS6, MRPL36, p = 2.81 x 10(-6)), 5q11.2 (ESM1, p = 6.59 x 10(-6)), and 9p23 (TYRP1, LURAP1L, p = 8.69 x 10(-6)). The genes located in or near the risk loci are expressed in neural or lung tissues, and have been previously associated with respiratory diseases such as asthma and COVID-19 or reported as differentially expressed in COVID-19 gene expression profiling studies. Our results revealed novel risk loci for pneumonia and severe COVID-19 disease which could contribute to a better understanding of the COVID-19 host genetics in different populations.

This is the first study from Serbia that performed a GWAS of COVID-19 outcomes to identify genetic risk markers of disease severity. A group of 128 hospitalized COVID-19 patients from the Serbian population was enrolled in the study. We conducted a GWAS comparing (1) patients with pneumonia (n = 80) against patients without pneumonia (n = 48), and (2) severe (n = 34) against mild disease (n = 48) patients, using a genotyping array followed by imputation of missing genotypes. We have detected a significant signal associated with COVID-19 related pneumonia at locus 13q21.33, with a peak residing upstream of the gene KLHL1 (p = 1.91 x 10(-8)). Our study also replicated a previously reported COVID-19 risk locus at 3p21.31, identifying lead variants in SACM1L and LZTFL1 genes suggestively associated with pneumonia (p = 7.54 x 10(-6)) and severe COVID-19 (p = 6.88 x 10(-7)), respectively. Suggestive association with COVID-19 pneumonia has also been observed at chromosomes 5p15.33 (IRX, NDUFS6, MRPL36, p = 2.81 x 10(-6)), 5q11.2 (ESM1, p = 6.59 x 10(-6)), and 9p23 (TYRP1, LURAP1L, p = 8.69 x 10(-6)). The genes located in or near the risk loci are expressed in neural or lung tissues, and have been previously associated with respiratory diseases such as asthma and COVID-19 or reported as differentially expressed in COVID-19 gene expression profiling studies. Our results revealed novel risk loci for pneumonia and severe COVID-19 disease which could contribute to a better understanding of the COVID-19 host genetics in different populations.",

AB  - Pharmacogenomics and pharmacotranscriptomics contribute to more efficient and safer treatment of many diseases, especially malignancies. Acute lymphoblastic leukemia (ALL) is the most common hematological malignancy during childhood. Glucocorticoids, prednisone and dexamethasone, represent the basis of chemotherapy in pediatric ALL. Therapy causes side effects in 75% of patients and 1–3% of pediatric ALL patients die because of therapy side effects rather than the disease itself. Due to this fact, pharmacogenomics and pharmacotranscriptomics have gained key positions in this field. There is a growing knowledge of pharmacogenomics and pharmacotranscriptomics markers relevant for the success of the glucocorticoid treatment of children with ALL. New technologies, such as next-generation sequencing (NGS) have created a possibility for designing panels of pharmacogenomics and pharmacotranscriptomics markers related to the response to glucocorticoid drugs. Optimization of these panels through population pharmacogenomic studies leads to new knowledge that could open the doors widely to pre-emptive pharmacogenomic testing.

AB  - Clinical picture and course of the disease in patients with COVID-19 vary from asymptomatic to lethal.
Precision medicine could discover the cause of this phenomenon by analyzing the individual genomic
profiles of the patients.
We aimed to understand a host genetic component of COVID-19 focusing on variants in genes encoding
proteases and genes involved in innate immunity, important for susceptibility and resistance to SARS-CoV-2
infection. Also, we wanted to identify phamracogenes and pharmacogenomics markers associated with
drugs used for COVID-19 treatment in different clinical protocols in Serbia, and to compare the results
with various world populations.
Genotype information of 143 individuals of Serbian origin was extracted from database previously obtained
using TruSight One Gene Panel (Illumina). Variants in genes encoding proteases and genes involved in innate
immunity were identified and analysed in silico (PolyPhen-2, SIFT, MutPred2, Swiss-Pdb Viewer) to predict
the impact of the variants to the structure and/or function of proteins. Genotype data from Serbian population
was compared with European and 4 super-populations (total 2504 subjects). Data were extracted from
VCF files of Phase 3 variant calls of the 1000 Genomes Project (1kGP) sample collection via Ensembl Data
Slicer Tool. The level of population genetic variability at each selected loci was examined using the maximal
global differences in minor allele frequencies (delta MAF) calculated by subtracting the maximum and the
minimum MAF across analyzed population groups, and Fst statistics. Fisher exact test was used to measure
differences in genotypes distributions between Serbian and 1kGP populations, applying Bonferoni correction.
R software was utilized for genotype data manipulation and statistical calculations.
Based on high alternative allele frequencies in population and the functional effect of the variants, we identified
variants in genes encoding proteases and involved in the innate immunity that might be relevant for the
host response to SARS-CoV-2 infection. The potential pharmacogenomics markers in pharmacogenes relevant
for COVID-19 treatment were also identified. Bioinformatics tools integrated into precision medicine
could contribute to better understanding of inter-individual and population-specific genetic susceptibility and
resistance to the SARS-CoV-2 infection, therapy response inconsistencies, and could be applied to improve
the outcome of the COVID-19 patients.

AB  - Background: COVID-19 pandemic has proved to be an unrelenting health threat for more than a year now. The emerging amount of data indicates that vitamin D, zinc and selenium could be important for clinical presentation of COVID-19. Here, we investigated association of genetic variants related to the altered level and bioavailability of vitamin D, zinc and selenium with clinical severity of COVID-19. Methods: We analyzed variants in genes significant for the status of vitamin D (DHCR7/NADSYN1 rs12785878, GC rs2282679, CYP2R1 rs10741657, and VDR rs2228570), zinc (PPCDC rs2120019) and selenium (DMGDH rs17823744) in 120 Serbian adult and pediatric COVID-19 patients using allelic discrimination. Furthermore, we carried out comparative population genetic analysis among European and other worldwide populations to investigate variation in allelic frequencies of selected variants. Results: Study showed that DHCR7/NADSYN rs12785878 and CYP2R1 rs10741657 variants were associated with severe COVID-19 in adults (p = 0.03, p = 0.017, respectively); carriers of DHCR7/NADSYN TG+GG and CYP2R1 GG genotypes had 0.21 and 5.9 the odds for developing severe disease, OR 0.21 (0.05-0.9) and OR 5.9 (1.4-25.2), respectively. There were no associations between selected genetic variants and disease severity in pediatric patients. Comparative population genetic analysis revealed that Serbian population had the lowest frequency of CYP2R1 rs10741657 G allele compared to other non-Finish Europeans (0.58 compared to 0.69 and 0.66 in Spanish and Italian population, respectively), suggesting that other populations should also investigate the relationship of CYP2R1 variant and the COVID-19 disease course. Conclusion: The results of the study indicated that vitamin D related genetic variants were implicated in severe COVID-19 in adults. This could direct prevention strategies based on population specific nutrigenetic profiles.

AB  - Novi koronavirus SARS-CoV-2, uzročnik upale pluća, sposoban je da zarazi ljude i izazove novu bolest COVID- 19 koja je preopteretila zdravstvene sisteme širom planete i izazvala globalnu ekonomsku krizu. Klinička slika i tok bolesti kod pacijenata obolelih od COVID-19 varira od asimptomatske do letalnog ishoda. Kako se radi o istom uzročniku bolesti, individualni genomski profil pacijenta krije odgovor na pitanje medicinske nauke o uzroku ovog fenomena. U radu su sumirana dosadašnja znanja o genetičkim markerima koji su odgovorni za široki spektar kliničkih slika, kao i da li se već može primeniti individualizovan pristup lečenju. Prikazane su dosada istraživane varijante u genima (sa osvrtom na populacione specifičnosti) odgovorne za predispoziciju i odgovor na SARS-CoV-2 virusnu infekciju, farmakogenetičke varijante od značaja za lekove koji se koriste u lečenju pacijenata obolelih od COVID-19, kao i nutrigenetički markeri u genima važnim za metabolizam mikronutrijenata, vitamina D, selena i cinka, koji se takođe koriste u terapiji pacijenata sa COVID-19. Udruženi napor istraživača, multidisciplinarni pristup, dostupnost modernih tehnologija koje imaju kapacitet analize celokupnih genoma, buduće sveobuhvatnije studije sa dobro okarakterisanim grupama pacijenata, kao i razvoj robusnijih bioinformatičkih alata koji koriste mašinsko učenje i napredne statističke metode, omogućiće identifikaciju novih genetičkih markera čoveka povezanih sa COVID-19, bolje razumevanje same patofiziologije bolesti, razvoj prave ciljane terapije kao i istaći značaj nutrigenomike i farmakogenomike za primenu personalizovane medicine u lečenju COVID-19.
AB  - The new cause of pneumonia, coronavirus SARS-CoV-2, capable of infecting people and causing the new disease
COVID-19, overloaded health systems around the planet and caused a global economic crisis. The clinical
presentation and the course of the disease in COVID-19 patients vary from asymptomatic to lethal. As it
is the same cause of the disease, the individual genomic profile of the patient reveals the answer to the
question of medical science about the cause of this phenomenon. The paper summarizes the current knowledge
about genetic markers responsible for a wide range of clinical pictures, as well as whether an individualized
approach to treatment can already be applied. The variants identified so far in genes (with reference
to population specifics) responsible for predisposition and response to SARS-CoV-2 viral infection, pharmacogenetic
variants of importance for drugs used in the treatment of patients with COVID-19, as well as nutrigenetic
markers in genes important for the metabolism of the micronutrients, vitamin D, selenium and
zinc, also used in the therapy of patients with COVID-19, are presented. The combined effort of researchers,
a multidisciplinary approach, the availability of modern technologies that have the capacity to analyze entire
genomes, future more comprehensive studies with well-characterized patient groups, and the development
of more robust bioinformatics tools using machine learning and advanced statistical methods will
enable the identification of novel human genetic markers associated with COVID -19, better understanding
of the pathophysiology of the disease, development of the proper targeted therapy as well as point out the
importance of nutrigenomics and pharmacogenomics for the application of personalized medicine in the
treatment of COVID-19.

abstract = "Novi koronavirus SARS-CoV-2, uzročnik upale pluća, sposoban je da zarazi ljude i izazove novu bolest COVID- 19 koja je preopteretila zdravstvene sisteme širom planete i izazvala globalnu ekonomsku krizu. Klinička slika i tok bolesti kod pacijenata obolelih od COVID-19 varira od asimptomatske do letalnog ishoda. Kako se radi o istom uzročniku bolesti, individualni genomski profil pacijenta krije odgovor na pitanje medicinske nauke o uzroku ovog fenomena. U radu su sumirana dosadašnja znanja o genetičkim markerima koji su odgovorni za široki spektar kliničkih slika, kao i da li se već može primeniti individualizovan pristup lečenju. Prikazane su dosada istraživane varijante u genima (sa osvrtom na populacione specifičnosti) odgovorne za predispoziciju i odgovor na SARS-CoV-2 virusnu infekciju, farmakogenetičke varijante od značaja za lekove koji se koriste u lečenju pacijenata obolelih od COVID-19, kao i nutrigenetički markeri u genima važnim za metabolizam mikronutrijenata, vitamina D, selena i cinka, koji se takođe koriste u terapiji pacijenata sa COVID-19. Udruženi napor istraživača, multidisciplinarni pristup, dostupnost modernih tehnologija koje imaju kapacitet analize celokupnih genoma, buduće sveobuhvatnije studije sa dobro okarakterisanim grupama pacijenata, kao i razvoj robusnijih bioinformatičkih alata koji koriste mašinsko učenje i napredne statističke metode, omogućiće identifikaciju novih genetičkih markera čoveka povezanih sa COVID-19, bolje razumevanje same patofiziologije bolesti, razvoj prave ciljane terapije kao i istaći značaj nutrigenomike i farmakogenomike za primenu personalizovane medicine u lečenju COVID-19., The new cause of pneumonia, coronavirus SARS-CoV-2, capable of infecting people and causing the new disease
COVID-19, overloaded health systems around the planet and caused a global economic crisis. The clinical
presentation and the course of the disease in COVID-19 patients vary from asymptomatic to lethal. As it
is the same cause of the disease, the individual genomic profile of the patient reveals the answer to the
question of medical science about the cause of this phenomenon. The paper summarizes the current knowledge
about genetic markers responsible for a wide range of clinical pictures, as well as whether an individualized
approach to treatment can already be applied. The variants identified so far in genes (with reference
to population specifics) responsible for predisposition and response to SARS-CoV-2 viral infection, pharmacogenetic
variants of importance for drugs used in the treatment of patients with COVID-19, as well as nutrigenetic
markers in genes important for the metabolism of the micronutrients, vitamin D, selenium and
zinc, also used in the therapy of patients with COVID-19, are presented. The combined effort of researchers,
a multidisciplinary approach, the availability of modern technologies that have the capacity to analyze entire
genomes, future more comprehensive studies with well-characterized patient groups, and the development
of more robust bioinformatics tools using machine learning and advanced statistical methods will
enable the identification of novel human genetic markers associated with COVID -19, better understanding
of the pathophysiology of the disease, development of the proper targeted therapy as well as point out the
importance of nutrigenomics and pharmacogenomics for the application of personalized medicine in the
treatment of COVID-19.",

AB  - Research of inflammatory bowel disease (IBD) has identified numerous molecular players involved in the disease development. Even so, the understanding of IBD is incomplete, while disease treatment is still far from the precision medicine. Reliable diagnostic and prognostic biomarkers in IBD are limited which may reduce efficient therapeutic outcomes. High-throughput technologies and artificial intelligence emerged as powerful tools in search of unrevealed molecular patterns that could give important insights into IBD pathogenesis and help to address unmet clinical needs. Machine learning, a subtype of artificial intelligence, uses complex mathematical algorithms to learn from existing data in order to predict future outcomes. The scientific community has been increasingly employing machine learning for the prediction of IBD outcomes from comprehensive patient data-clinical records, genomic, transcriptomic, proteomic, metagenomic, and other IBD relevant omics data. This review aims to present fundamental principles behind machine learning modeling and its current application in IBD research with the focus on studies that explored genomic and transcriptomic data. We described different strategies used for dealing with omics data and outlined the best-performing methods. Before being translated into clinical settings, the developed machine learning models should be tested in independent prospective studies as well as randomized controlled trials.

AB  - Methotrexate (MTX) is one of the staples of pediatric acute lymphoblastic leukemia (ALL) treatment. MTX targets the folate metabolic pathway (FMP). Abnormal function of the enzymes in FMP, due to genetic aberrations, leads to adverse drug reactions. The aim of this study was to investigate variants in pharmacogenes involved in FMP and their association with MTX pharmacokinetics (MTX elimination profile) and toxicity in the consolidation therapy phase of pediatric ALL patients. Eleven variants in the thymidylate synthetase (TYMS), methylenetetrahydrofolate reductase (MTHFR), dihydrofolate reductase (DHFR), SLC19A1 and SLCO1B genes were analyzed in 148 patients, using PCR- and sequencing-based methodology. For the Serbian and European control groups, data on allele frequency distribution were extracted from in-house and public databases. Our results show that the A allele of SLC19A1 c.80 variant contributes to slow MTX elimination. Additionally, the AA genotype of the same variant is a predictor of MTX-related hepatotoxicity. Patients homozygous for TYMS 6bp deletion were more likely to experience gastrointestinal toxicity. No allele frequency dissimilarity was found for the analyzed variants between Serbian and European populations. Statistical modelling did not show a joint effect of analyzed variants. Our results indicate that SLC19A1 c.80 variant and TYMS 6bp deletion are the most promising pharmacogenomic markers of MTX response in pediatric ALL patients.

AB  - New coronavirus SARS-CoV-2 is capable to infect humans and cause a novel disease COVID-19. Aiming to understand a host genetic component of COVID-19, we focused on variants in genes encoding proteases and genes involved in innate immunity that could be important for susceptibility and resistance to SARS-CoV-2 infection. Analysis of sequence data of coding regions of FURIN, PLG, PRSS1, TMPRSS11a, MBL2 and OAS1 genes in 143 unrelated individuals from Serbian population identified 22 variants with potential functional effect. In silico analyses (PolyPhen-2, SIFT, MutPred2 and Swiss-Pdb Viewer) predicted that 10 variants could impact the structure and/or function of proteins. These protein-altering variants (p.Gly146Ser in FURIN; p.Arg261His and p.Ala494Val in PLG; p.Asn54Lys in PRSS1; p.Arg52Cys, p.Gly54Asp and p.Gly57Glu in MBL2; p.Arg47Gln, p.Ile99Val and p.Arg130His in OAS1) may have predictive value for inter-individual differences in the response to the SARS-CoV-2 infection. Next, we performed comparative population analysis for the same variants using extracted data from the 1000 Genomes project. Population genetic variability was assessed using delta MAF and Fst statistics. Our study pointed to 7 variants in PLG, TMPRSS11a, MBL2 and OAS1 genes with noticeable divergence in allelic frequencies between populations worldwide. Three of them, all in MBL2 gene, were predicted to be damaging, making them the most promising population-specific markers related to SARS-CoV-2 infection. Comparing allelic frequencies between Serbian and other populations, we found that the highest level of genetic divergence related to selected loci was observed with African, followed by East Asian, Central and South American and South Asian populations. When compared with European populations, the highest divergence was observed with Italian population. In conclusion, we identified 4 variants in genes encoding proteases (FURIN, PLG and PRSS1) and 6 in genes involved in the innate immunity (MBL2 and OAS1) that might be relevant for the host response to SARS-CoV-2 infection.

AB  - Uvod: Kako ne postoje odobreni terapeutici za lečenje pacijenata sa COVID-19, mogućnost upotrebe postojećih lekova je postala važna. U nedostatku vremena za testiranje farmakogenomskih markera kod pojedinaca, populaciona farmakogenomika bi mogla biti od koristi u predviđanju povećanog rizika za pojavu neželjenih reakcija i neuspeha lečenja kod pacijenata sa COVID-19. Cilj naše studije bio je identifikovanje farmakogena i farmakogenomskih markera povezanih sa lekovima koji se preporučuju za lečenje COVID-19, hlorokin/hidroksihlorokin, azitromicin, lopinavir i ritonavir, u populaciji Srbije i drugim svetskim populacijama. Metode: Podaci o genotipu 143 osobe srpskog porekla dobijeni su iz baze podataka prethodno formirane analizama genoma korišćenjem TruSight One Gene Panel (Illumina).

Zaključak: Uzimajući u obzir farmakogenomski profil specifičan za populaciju, preventivno testiranje farmakogena značajnih za lekove koji se koriste u lečenju COVID-19 moglo bi doprineti boljem razumevanju interindividualnih razlika u odgovorima na terapiju i poboljšanju ishoda lečenja pacijenata sa COVID-19.
AB  - Background: Since there are no certified therapeutics to treat COVID-19 patients, drug repurposing became important. With lack of time to test individual pharmacogenomics markers, population pharmacogenomics could be helpful in predicting a higher risk of developing adverse reactions and treatment failure in COVID-19 patients. Aim of our study was to identify pharmacogenes and pharmacogenomics markers associated with drugs recommended for COVID-19 treatment, chloroquine/hydroxychloroquine, azithromycin, lopinavir and ritonavir, in population of Serbia and other world populations. Methods: Genotype information of 143 individuals of Serbian origin was extracted from database previously obtained using TruSight One Gene Panel (Illumina). Genotype data of individuals from different world populations were extracted from the 1000 Genome Project. Fisher's exact test was used for comparison of allele frequencies. Results: We have identified 11 potential pharmacogenomics markers in 7 pharmacogenes relevant for COVID-19 treatment. Based on high alternative allele frequencies in population and the functional effect of the variants, ABCB1 rs1045642 and rs2032582 could be relevant for reduced clearance of azithromycin, lopinavir and ritonavir drugs and UGT1A7 rs17868323 for hyperbilirubinemia in ritonavir treated COVID-19 patients in Serbian population. SLCO1B1 rs4149056 is a potential marker of lopinavir response, especially in Italian population. Our results confirmed that pharmacogenomics profile of African population is different from the rest of the world. Conclusions: Considering population specific pharmacogenomics landscape, preemptive testing for pharmacogenes relevant for drugs used in COVID-19 treatment could contribute to better understanding of the inconsistency in therapy response and could be applied to improve the outcome of the COVID-19 patients.

abstract = "Uvod: Kako ne postoje odobreni terapeutici za lečenje pacijenata sa COVID-19, mogućnost upotrebe postojećih lekova je postala važna. U nedostatku vremena za testiranje farmakogenomskih markera kod pojedinaca, populaciona farmakogenomika bi mogla biti od koristi u predviđanju povećanog rizika za pojavu neželjenih reakcija i neuspeha lečenja kod pacijenata sa COVID-19.

AB  - Background: This study analyzed poorly understood relationship of two overlapping conditions: metabolic syndrome (MeS) and inflammatory bowel disease (IBD), both associated with inflammation in the visceral adipose tissue. Methods: Newly diagnosed 104 IBD patients, of which 50 Crohn's disease (CD) and 54 ulcerative colitis (UC), and 45 non-IBD controls were examined for MeS-related obesity and lipid markers. Th-17 immune genes IL17A, IL17F, IL23A, and TLR9 mRNAs were measured in intestinal mucosa by qRT-PCR. Subjects were genotyped for obesity-associated FTO variant rs9939609 by polymerase chain reaction-amplification refractory mutation system. Results: CD was associated with MeS (P = 0.01), while both CD and UC were associated with central obesity (P = 10(-5), P = 0.002, respectively) and low levels of high-density lipoprotein (HDL) cholesterol (P = 5 x 10(-6), P = 6 x 10(-6), respectively). IBD lipid profile was characterized by decreased total and HDL cholesterol, while low-density lipoprotein cholesterol was reduced only in CD. Negative correlations were found between total cholesterol and CD activity index (P = 0.005), waist circumference and IL17A as well as IL17F mRNA levels in inflamed CD colon (P = 0.003, P = 0.001, respectively). Carriers of FTO rs9939609 AA genotype showed increased risk of CD (OR 2.6, P = 0.01). Conclusions: MeS, central obesity, and dyslipidemia could be important for IBD pathogenesis. This could influence therapeutic approaches and prevention strategies in high-risk groups.

AB  - Background: Crohn's disease (CD) is chronic inflammatory bowel disease with different phenotypic characteristics influencing disease prognosis and therapeutic strategies. The aim of this pilot study was to analyze selected inflammatory and apoptotic markers in non-inflamed and inflamed samples of ileal mucosa of non-stricturing/non-penetrating (NS/NP) and stricturing (S) CD mucosal phenotypes in order to characterize their distinct profiles. Methods: From twenty CD patients (9 NS/NP, 11 S) paired non-inflamed and inflamed ileal biopsies were collected and used for analysis of cytokine (TNF and IL6) and apoptotic (Bcl2, Box, Fas and FasL) genes' expression levels by real-time PCR, while NF kappa B transcriptional potency was assessed by electromobility gel shift assay. Results: Our results demonstrated significant upregulation of TNF and IL6 in inflamed area of both NS/NP (p = 0.03, p = 0.01) and S phenotypes (p = 0.04, p = 0.04), respectively. However, TNF increase was more prominent in NS/NP compared to S inflamed mucosa (p = 0.02). Also, level of proapoptotic Box was significantly higher in NS/NP compared to S inflamed mucosa (p = 0.01). Opposing transcription potency of NF kappa B has been detected between two phenotypes: being decreased in NS/NP (p = 0.07) and increased in S (p = 0.1) inflamed compared to non-inflamed mucosa, demonstrating trend towards statistical significance. Conclusions: We found that two distinct CD phenotypes have specific molecular signatures. Obtained results could direct improvement of current and development of new therapeutic strategies based on more specific molecular stratification of CD patients.

AB  - Background: Thiopurine drugs are used for the treatment of pediatric diseases. Inter-individual differences in the metabolism of these drugs greatly influence the risk of thiopurine induced toxicity and therapy failure. These differences are the consequence of genomic, epigenomic and transcriptomic variability among patients. Pharmacogenomics aims to individualize therapy according to the specific genetic signature of a patient. Treatment protocols based on thiopurine drugs have already been improved by applying pharmacogenomics in pediatric clinical practice. Objective: The aim of this review was to summarize the application of thiopurine pharmacogenomics in pediatric patients suffering from acute leukemias, different types of autoimmune and inflammatory diseases, as well as in posttransplant care. Methods: We searched PubMed/Medline database to identify thiopurine pharmacogenomic markers clinically relevant in pediatric diseases. Results: TPMT and NUDT15 pharmacogenomic testing is done in pediatric care, contributing to the reduction of thiopurine induced toxicity. Data on numerous novel potential pharmacogenomic markers relevant for optimization of thiopurine treatment are still controversial (ITPA, ABCC4, NT5C2, PRPS1, GSTM1, FTO gene variants). Majority of evidences regarding thiopurine pharmacogenomics in pediatrics have been acquired by studying acute lymphoblastic leukemia and inflammatory bowel disease. For other pediatric diseases, namely acute myeloid leukemia, non-Hodgkin lymphoma, juvenile idiopathic arthritis, atopic dermatitis, juvenile autoimmune hepatitis and renal allograft transplantation, data are still scarce. Conclusion: Thiopurine pharmacogenomics has shown to be one of the best examples of successful application of pharmacogenomics in pediatrics.
