Abstract

Background

Elevated concentrations of IL-10 have been detected in coronavirus disease (COVID-19) patients and are a possible disease severity marker. Single nucleotide variants (SNVs) and their haplotypes can be associated with differences in IL-10 levels and with viral disease susceptibility.

Aim

Evaluate the associations of SNVs and their haplotypes in Brazilian patients with COVID-19 severity and outcome.

Methods

In this cross-sectional and case-control study, the patients were selected from the University Hospital of State University of Londrina (HU-UEL) (n = 367) and were subdivided into mild (n = 165), moderate (n = 72) and severe (n = 130) groups. The DNA samples of the participants were subjected to real-time PCR for the detection of rs1800896 (A>G), rs1800871 (C>T) and rs1800872 (C>A) genotypes. The haplotypes were inferred with PHASE v2.1.1.

Results

The severe cases of COVID-19 were independently associated with the GG genotype (rs1800896) (P = 0.038, OR 2.522, 95 % CI 1.053–6.038) as well as with the GCC haplotype in homozygosity (P = 0.037, OR 2.767, 95 % CI 1.065–7.191).

Conclusion

These results showed that the GG genotype of rs1800896 or the GCC haplotype are associated with COVID-19 severity in Brazilian patients.

期刊介绍： The journal''s scope includes understanding the genetic and functional mechanisms that distinguish human individuals in their immune responses to allografts, pregnancy, infections or vaccines as well as the immune responses that lead to autoimmunity, allergy or drug hypersensitivity. It also includes examining the distribution of the genes controlling these responses in populations. Research areas include: Studies of the genetics, genomics, polymorphism, evolution, and population distribution of immune-related genes Studies of the expression, structure and function of the products of immune-related genes Immunogenetics of susceptibility to infectious and autoimmune disease, and allergy The role of the immune-related genes in hematopoietic stem cell, solid organ, and vascularized composite allograft transplant Histocompatibility studies including alloantibodies, epitope definition, and T cell alloreactivity Studies of immunologic tolerance and pregnancy T cell, B cell, NK and regulatory cell functions, particularly related to subjects within the journal''s scope Pharmacogenomics and vaccine development in the context of immune-related genes Human Immunology considers immune-related genes to include those encoding classical and non-classical HLA, KIR, MIC, minor histocompatibility antigens (mHAg), immunoglobulins, TCR, BCR, proteins involved in antigen processing and presentation, complement, Fc receptors, chemokines and cytokines. Other immune-related genes may be considered. Human Immunology is also interested in bioinformatics of immune-related genes and organizational topics impacting laboratory processes, organ allocation, clinical strategies, and registries related to autoimmunity and transplantation.
