Objective: Chronic liver disease has become a leading cause of illness and death in people living with HIV and the production of the cytokines IFN-γ and TGF-β1, and chemokine CXCL10 during chronic inflammation contributes to liver disease progression in HIV patients under long-term anti-retroviral therapy. This study aimed to examine association of IFN-γ +874T/A, CXCL10 G-201A and C-1596T, and TGF-β1 -509C/T single nucleotide polymorphisms (SNPs) with liver complications in the HIV-infected Thais.
Methods: A cross-sectional study was conducted in 200 Thai HIV patients who were evaluated for transaminitis and significant liver fibrosis by fibrosis-4 score (FIB-4), and genotypes for IFN-γ +874T/A, CXCL10 G-201A and C-1596T, and TGF-β1 -509C/T SNPs using PCR-based methods.
Result: There were high rates of transaminitis (30.1%) and significant liver fibrosis assessed by FIB-4 score > 1.45 (18.8%) in this group of patients, mostly under anti-retroviral therapy (73.0%). The genotypes and alleles of IFN-γ +874T/A, CXCL10 G-201A and C-1596T, and TGF-β1 -509C/T SNPs were not associated with either transaminitis or FIB-4 score > 1.45 (p > 005). Logistic regression analysis identified age and gender as risk factors, and CD4+ cell count higher than 350 cells/ul as a protective factor of liver fibrosis in this study group.
Conclusion: The IFN-γ +874T/A, CXCL10 G-201A and C-1596T, and TGF-β11 -509C/T SNPs were not significantly associated with liver complication in HIV-infected Thais, mostly under ART.

Article Synopsis
- Visceral leishmaniasis (VL) is a tropical disease caused by a parasite, influenced by environmental and genetic factors, particularly the genetic variations in cytokine genes.
- This systematic review and meta-analysis evaluated the impact of specific single nucleotide polymorphisms (SNPs) in interleukin genes on the susceptibility or resistance to VL, using data from multiple scientific databases.
- The analysis revealed significant associations between SNPs in the IFN-γ and IL-18 genes with VL, suggesting that these genetic variations could influence disease outcomes, while no significant links were found for IL-10 gene SNPs.

Tumor necrosis factor (TNF) and interferon-gamma (IFNγ) are important inflammatory mediators in the development of cytokine storm syndrome (CSS). Single nucleotide polymorphisms (SNPs) regulate the expression of these cytokines, making host genetics a key factor in the prognosis of COVID-19. In this study, we investigated the associations of the -308G/A and +874T/A polymorphisms with COVID-19.

Introduction: Genetic studies have shown associations of several single nucleotide polymorphisms (SNP) with different rates of progression and variation in susceptibility to HIV infection. This study aimed to estimate the frequency of ccr5Δ32, IL-6-174G/C, IFN-γ+874T/A and IL-10-1082A/G polymorphisms in Cuban HIV-infected patients and a group of sero-discordant couples to assess their influence on risk and disease progression.
Methods: A cross-sectional study was carried out on 120 subjects registered at the Institute of Tropical Medicine «Pedro Kour» (IPK) and the Ameijeiras Hospital from June 2018 until December 2019.

Studies on the association between gene polymorphisms of various inflammatory factors and liver cirrhosis have been inconsistent. The purpose of this study was to comprehensively summarize the available evidence on the association between gene polymorphisms of inflammatory factors and liver cirrhosis through a systematic review. We searched databases of PubMed, EMBASE, Web of Science, and the Cochrane Library for relevant articles published from building databases to 25 September 2022.
