Impact of IL-6 and IL-6r variants on HIV-1 susceptibility and progression to AIDS: a case-control study in a Moroccan population. NUCLEOSIDES, NUCLEOTIDES & NUCLEIC ACIDS 2024:1-20. [PMID: 38830242 DOI: 10.1080/15257770.2024.2359593] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/07/2023] [Accepted: 05/16/2024] [Indexed: 06/05/2024]
Abstract
Interleukin-6 (IL-6), a pro-inflammatory cytokine, is an important regulator of the inflammatory immune response. We aimed to assess the association of common single nucleotide polymorphisms (SNPs) in IL-6 (rs1800795 G > C, rs1800797 A > G) and interleukin-6 receptor (IL-6R) (rs2228145 A > C) genes with HIV-1 infection, AIDS progression, and response to treatment. In this case-control study involving 199 individuals living with HIV-1 and 200 HIV-uninfected controls, we conducted genotyping of IL-6/IL-6R SNPs using TaqMan real-time PCR assays. Soluble IL-6 levels were measured using ELISA. No associations were found between the investigated SNPs and HIV infection. However, a significant association was noted between the C-G and G-A haplotypes and susceptibility to HIV-1 infection. Additionally, a significant association was revealed between HIV-1 RNA viral loads and IL-6 SNP G > C in the post-treatment HIV group. Interestingly, we observed a significant association between the investigated SNPs and protection against progression to AIDS, namely the IL-6 G > A SNP in its recessive model and the IL-6R A > C SNP in its codominant and dominant models. Nevertheless, we found no significant differences between IL-6 levels and the different genotypes and alleles of the IL-6 gene either before or after combination antiretroviral therapy. IL-6 promoter haplotypes are associated with susceptibility to HIV-1 infection. Furthermore, IL-6 A > G and IL-6R A > C polymorphisms have been associated with protection against AIDS progression. Interestingly, the IL-6 G > C SNP may affect the response to treatment in people living with HIV-1.

Abstract
The pro-inflammatory (Th1) cytokines namely interleukin (IL)-2, IL-6, IL-12, interferon (IFN)-γ, tumor necrosis factor-α (TNF-α) are vital in the clearance of HIV infection. This prospective cohort study aimed to evaluate the polymorphisms of Th1 cytokine genes and their corresponding plasma cytokine levels in HIV-1 positive and exposed uninfected (EU) infants born to HIV-1 positive mothers. CD4 count, viral load of HIV-1 positive mothers was done using commercially available reagents. Cytokine genotyping analysis and levels were done in 20 HIV-1 positive and 54 EU infants. The polymorphisms of Th1 cytokines were done using the PCR-SSP method. Plasma cytokine levels were estimated using Bio-Plex-Pro cytokine assay (BIO-RAD; USA). Results revealed treatment status of the mothers and viral load were the two confounding factors having a significant effect on HIV status of the infant. TNF-α GG genotype is significantly higher in EU infants as compared with HIV-1 positive infants. GG genotype was associated with high TNF- α levels in HIV-1 positive infants but the difference was not statistically significant. HIV-1 positive infants with -IFN-γ (+874) TT genotype was significantly associated with high IFN-γ levels. To the best of our knowledge, this is the first study reporting the role of Th1 cytokine gene polymorphisms and their corresponding plasma cytokine levels in HIV-1 positive and EU infants from India.

Abstract
BACKGROUND This study meta-analyzed the literature on possible association of 3 polymorphisms (-592, -1082, -819) in the interleukin-10 (IL-10) gene with susceptibility to human immunodeficiency virus (HIV)-1 infection. METHODS PubMed, EMBASE, MEDLINE and Google Scholar were systematically searched to identify relevant studies in English. Meta-analyses were performed to examine the association of IL-10 polymorphisms -592, -1082, and -819 with susceptibility to HIV-1 infection. RESULTS A significant association between the -592 polymorphism and susceptibility to HIV-1 infection was found in the total population (recessive model, odds ratios (OR) = 1.44, 95% CI = 1.06-1.96, P = .02; homozygous model, OR = 1.44, 95% CI = 1.02-2.02, P = .04). However, these results were not observed in subgroups based on ethnicity. The -1082 polymorphism was significantly associated with susceptibility to HIV-1 infection in Caucasians (OR = 1.30, 95% CI = 1.05-1.62, P = .02; recessive model, OR = 1.49, 95% CI = 1.09-2.03, P = .01; homozygous model, OR = 1.58, 95% CI = 1.01-2.46, P = .04), but not in Asians or the total population. None of the 5 genetic models suggested a significant association between the -819 polymorphism and HIV-1 infection. CONCLUSION The available evidence indicates that the AA genotype of IL-10 -592 may confer increased susceptibility to HIV-1 infection, and that the AA genotype of -1082 may confer increased susceptibility in Caucasians. In contrast, the -819 polymorphism may not be associated with HIV-1 infection risk. These conclusions should be verified in large, well-designed studies.

Abstract
OBJECTIVE In this study, we investigated the changes in peripheral blood inflammatory factors and intestinal flora in acquired immune deficiency syndrome (AIDS) and human immunodeficiency virus (HIV)-positive individuals (AIDS/HIV patients), and explored the relationships among intestinal flora, peripheral blood inflammatory factors, and CD4+ T lymphocytes. METHODS Thirty blood and stool samples from an AIDS group and a control group were collected. The levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) were determined by enzyme-linked immunosorbent assay (ELISA), and the number of CD4+ T lymphocytes by a FACSCount automated instrument. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to determine the messenger RNA (mRNA) levels of Bifidobacterium, Lactobacillus, Escherichia coli, Enterococcus faecalis, and Enterococcus faecium. Correlations among intestinal flora, inflammatory factor levels, and CD4+ T lymphocyte values were evaluated using the Spearman correlation coefficient. RESULTS The levels of TNF-α and IL-6 in the AIDS group were higher than those in the control group, while the number of CD4+ T lymphocytes was lower. The amounts of Bifidobacterium and Lactobacillus in the AIDS group were significantly lower than those in control group, while the amounts of E. coli, E. faecalis, and E. faecium were much higher. The amounts of Bifidobacterium and Lactobacillus were negatively correlated with the content of TNF-α and IL-6 and the CD4+ T lymphocyte count, while those correlations were reversed for E. coli, E. faecalis, and E. faecium. CONCLUSIONS The intestinal microbiota of AIDS/HIV patients were disordered, and there was a correlation between the amount of intestinal flora and the number of CD4+ T lymphocytes and the levels of TNF-α and IL-6.

Abstract
The progression of AIDS depends on the complex host and virus interactions. The most important disease progression hallmarks are immune activation and apoptosis. In this study, we address the prevalence of polymorphisms related to proinflammatory and apoptotic genes, such as IFNG (+874T/A), TNF (308G/A), IL6 (-174G/C), IL8 (-251A/T), FAS (-670A/G), and FASL (-124A/G) in 160 ethnically mixed HIV-1-infected patients from multicentre cohorts with different clinical outcomes (13 elite controllers [EC], 66 slow long-term non-progressors [LTNPs], and 81 progressors [P]). The genotyping was accomplished by TaqMan-qPCR. Among all the polymorphisms analyzed in the cytokines, the IL6 -174G/C polymorphism showed a higher frequency of GG genotype in the LTNP and LTNP+EC groups as compared to the P group. Moreover, there was a significantly higher frequency of the G allele in the LTNP and LTNP+EC groups as compared to the P group. On the other hand, the levels of CD4+ T lymphocytes were higher among individuals showing the AA and AG genotypes for the FASL -124A/G polymorphism as compared to the GG genotype. Furthermore, the AG and AA genotypes were more frequent, as compared to the GG genotype, in individuals showing a lower viral load. In contrast, for the FAS -670A/G polymorphism, a significantly higher viral load was observed in individuals with the AG genotype as compared to the GG genotype. In conclusion, we found three genetic allelic variants of the IL6 -174G/C, FASL -124A/G, and FAS -670A/G polymorphisms that were related to disease progression and immunological and virological markers in cohorts of HIV-1-positive ethnically mixed patients.

Abstract
Interleukin-10 (IL-10) is an anti-inflammatory cytokine associated with the inhibition of HIV replication. IL-10 polymorphisms were found to be linked to drug-induced hepatotoxicity. Hence we examined the prevalence of IL-10 (-819C/T,-1082A/G) polymorphisms in a total of 165 HIV patients which included 34 patients with hepatotoxicity, 131 without hepatotoxicity and 155 healthy controls by the PCR-RFLP method. In HIV patients with hepatotoxicity, the IL-10-819TT genotype increased the risk of ARV associated hepatotoxicity severity (OR = 1.61, P = 0.35). IL-10-819TT genotype was overrepresented in patients with hepatotoxicity as compared to healthy controls (26.5% vs. 13.5%, OR = 1.61, P = 0.46). IL-10 -819CT genotype was associated with advance HIV disease stage (OR = 0.49, P = 0.045). In HIV patients without hepatotoxicity, the IL-10-819TT genotype was more prevalent in patients consuming tobacco as compared to non-users (OR = 1.60, P = 0.41). In HIV patients without hepatotoxicity using both alcohol + efavirenz along with IL-10 -819CT genotype resulted in increased risk for the acquisition of ARV associated hepatotoxicity (OR = 4.00, P = 0.36). In multivariate logistic regression, taking nevirapine was associated with the risk hepatotoxicity severity (OR = 0.23, P = 0.005). In conclusion, an insignificant association between IL-10 polymorphisms and susceptibility to ARV associated hepatotoxicity.

HBV Viral Load and Liver Enzyme Levels May Be Associated with the Wild MBL2 AA Genotype. Mediators Inflamm 2017; 2017:3718451.

Abstract
The present study investigated the frequencies of rs1800450 (MBL ⁎B, G>A), rs1800451 (MBL ⁎C, G>A), and rs5030737 (MBL ⁎D, C>T) polymorphisms in exon 1 of the MBL2 gene among patients with chronic viral hepatitis. Blood samples from patients infected with hepatitis B virus (HBV; n = 65), hepatitis C virus (HCV; n = 92), and a noninfected control group (n = 300) were investigated. The presence of polymorphisms was detected using a real-time polymerase chain reaction to correlate with liver disease pathogenesis and fibrosis staging according to the Metavir classification. The genotypic and allelic frequencies showed no significant differences between the groups, but patients with active HBV and the wild AA genotype presented a positive correlation between increased transaminase and HBV DNA levels and the presence of mild to moderate fibrosis. Patients with HCV and the wild AA genotype presented mild inflammation and higher HCV RNA levels, although the same association was not observed for the fibrosis scores. The results suggest that the mutations in exon 1 of the MBL2 gene do not contribute directly to the clinical and laboratory features of HCV and HBV infections, but further studies should be performed to confirm whether the wild AA genotype has indirect effect on disease progression.

Abstract
The Interleukin-10 (IL-10) gene polymorphism influences the pathogenesis and evolution of HIV-1 disease. Many studies in this regard have evaluated the association between this polymorphism and HIV-1 susceptibility, yet, the exact relationship between them remains ambiguous and contradictory. A systematic literature search was conducted and the found case-control studies assessing the association between IL-10-1082G/A, -592C/A, -819C/T gene polymorphism and HIV-1 susceptibility were analyzed. The pooled odds ratios (ORs) and 95% confidence interval (CI) were calculated by a fixed effect model. In general, no significant relationship was found between IL-10-1082G/A gene polymorphism and susceptibility to HIV-1 infection (A vs. G genotype model: OR = 0.97, 95% CI = 0.81-1.23, p = .775; GG vs. AA+AG model: OR = 0.98, 95% CI = 0.76-1.27, p = .867; GG+AG vs. AA model: OR = 0.97, 95% CI = 0.70-1.35, p = .852; GG vs. AA model: OR = 0.88, 95% CI = 0.67-1.15, p = .348; AG vs. AA model: OR = 0.96, 95% CI = 0.67-1.37, p = .811; GG+AA vs. AG model: OR = 1.03, 95% CI = 0.74-1.43, p = .886). IL-10-529C/A gene polymorphism might lead to a decreased risk of HIV-1 infection (A vs. G genotype model: OR = 0.88, 95% CI = 0.73-1.06, p = .166; GG vs. AA+AG model: OR = 0.94, 95% CI = 0.80-1.11, p = .447; GG+AG vs. AA model: OR = 0.75, 95% CI = 0.61-0.92, p = .005; GG vs. AA model: OR = 0.73, 95% CI = 0.57-0.93, p = .012; AG vs. AA model: OR = 0.74, 95% CI = 0.60-0.92, p = .0.007; GG+AA vs. AG model: OR = 1.11, 95% CI = 0.72-1.71, p = .641). IL-10-819C/T gene polymorphism might lead to an increased risk of HIV-1 infection (A vs. G genotype model: OR = 1.25, 95% CI = 1.04-1.50, p = .019; GG vs. AA+AG model: OR = 1.29, 95% CI = 0.81-2.01, p = .278; GG+AG vs. AA model: OR = 1.42, 95% CI = 1.05-1.93, p = .023; GG vs. AA model: OR = 1.63, 95% CI = 1.11-2.38, p = .012; AG vs. AA model: OR = 1.32, 95% CI = 0.95-1.84, p = .094; GG+AA vs. AG model: OR = 0.92, 95% CI = 0.72-1.19, p = .537). In general, the meta-analysis found no marked association between the IL-10-1082G/A gene polymorphism and HIV-1 susceptibility, IL-10-529C/A gene polymorphism might lead to a decreased risk of HIV-1 infection, and IL-10-819C/T gene polymorphism might lead to an increased risk of HIV-1 infection.

Abstract
Rate of HIV disease progression varies considerably among individuals, host genetic makeup be one of the possible reasons. We aimed to determine association of functional single nucleotide polymorphism (SNPs), (-179G/T and +874T/A) in IFN-γ and (-1082A/G, -819C/T and -592C/A) in IL-10 genes, with the rate of disease progression or susceptibility to HIV infection. Therapy naïve HIV infected individuals from North India, categorized as slow progressors or fast progressors and HIV exposed seronegative individuals were recruited for this study. Genotyping results revealed significantly higher frequencies of low producer AA genotype at +874T/A in IFN-γ gene and -592C/A position in IL-10 gene in FPs (p<0.002). Multifactor dimensional reduction (MDR) analysis revealed this to be a high risk combination for faster disease progression in HIV-1 infected individuals. Low producer AA genotype carriers at +874T/A in IFN-γ gene produced significantly low amounts of cellular IFN-γ. Low producing haplotype 'ATA' at -1082, -819 and -592 loci in IL-10 gene was significantly over-represented in FPs as compared to SPs (p<0.01) and these individuals showed poor response to therapy in terms of CD4 count gains after one year of ART, compared to high producing haplotype (GCC) carriers. Thus, a combination of genetic variations in IFN-γ and IL-10 cytokine genes in a single host associate with HIV disease progression and may help clinicians to better manage the HIV disease if known earlier.

AIM The correlation between interleukin-6 (IL-6) gene polymorphism and polycystic ovary syndrome (PCOS) has been reported, but the conclusions are controversial. The present study was aimed to evaluate the association between IL-6 -174 G/C polymorphism and susceptibility of PCOS by meta-analysis. MATERIAL AND METHODS A systematic search on Medline, Embase, CNKI, Wanfang Data and VIP databases containing Chinese and English studies was conducted electronically using specific eligibility criteria. Meta-analysis was performed using Review Manager 5.2 software after Hardy-Weinberg equilibrium test. Effect sizes of odds ratio and 95% confidence interval (CI) were calculated and combined appropriately. To verify the reliability of the results, subgroup analyses and sensitivity analyses were performed. RESULTS Four selected studies containing 351 cases and 464 control participants were included. The pooled odds ratio between IL-6 -174 G/C polymorphism and susceptibility of PCOS under allele (C/G), dominant (CC+GC/GG) and recessive (CC/GG+GC) models were 0.63 (95%CI, 0.41-0.96), 0.53 (95%CI, 0.26-1.08) and 0.67 (95%CI, 0.39-1.16), respectively. The result under allele model was unstable in sensitivity analysis. Subgroup analysis showed that the correlation between IL-6 -174 G/C polymorphism and susceptibility of PCOS was not statistically significant in the studies that conformed to the Hardy-Weinberg equilibrium. CONCLUSION IL-6 -174 G/C polymorphism may be not related to susceptibility of PCOS. Nevertheless, further studies with large samples and studies considering other single-nucleotide polymorphisms of the IL-6 gene are needed to confirm our findings.

Abstract
BACKGROUND Cytokines and their genes have been described to have an influence on incidence and prognosis in malignant, infectious and autoimmune disease. We previously described the impact of cytokine production on prognosis in paediatric standard-risk acute lymphoblastic leukaemia (ALL). PROCEDURE In this study, we investigated the influence of cytokine gene polymorphisms (TNFα, TGFβ, IL10 and IFNγ) on frequency, risk group and prognosis in 95 paediatric ALL-patients. We further report on intracellular production of these cytokines in T-cells. RESULTS IL10 high-producer-haplotypes were reduced in ALL-patients compared with healthy controls and resulted in a reduced relapse rate compared with low-producer haplotypes. TGFβ high-producer-haplotypes were correlated with a high initial blast-count (codon 25: G/G) and were elevated in high-risk ALL-patients (codon 10: T/T). IL10 was positively and IFNγ-production was negatively correlated with initial blast-count. At diagnosis the expression of TNFα and IFNγ was reduced in patients compared with healthy controls. This was more pronounced in high-risk and in T-ALL-patients. CONCLUSION We conclude that gene-polymorphisms of the regulatory/anti-inflammatory cytokines, TGFβ and IL10, but not of the pro-inflammatory cytokines, IFNγ and TNFα, have an impact on prognosis and risk-group of ALL. However, the reduced capacity to produce pro-inflammatory cytokines at diagnosis may serve as another important, functional risk factor. These data may help in further risk stratification and adaptation of therapy-intensity in paediatric patients with ALL.

Abstract
Several host genetic factors play an important role in susceptibility to human immunodeficiency virus type 1 (HIV-1) infection and in its progression to acquired immune deficiency syndrome (AIDS). The interleukin-18 (IL-18) is a multifunctional proinflammatory cytokine that regulates immune responses and plays a pathogenic role in HIV-1 infection by enhancing viral replication. Single nucleotide polymorphisms (SNPs) in the IL-18 gene promoter region may lead to altered transcriptional activity and IL-18 production, and may account for variation in the risk of HIV-1 infection. We have investigated the association between IL-18 promoter polymorphism −607C>A and HIV-1 infection through a case-control study of 500 patients with HIV-1/AIDS and an equal number of age and sex matched controls in a north Indian population. Genotyping using sequence specific primer-polymerase chain reaction (SSP-PCR) showed a statistically significant reduced risk of HIV-1 infection for the A>A genotype [odds ratio (OR) = 0.57, 95% confidence interval (95% CI) = 0.33–0.98, p = 0.040], but not for the C>A genotype (OR = 0.87, 95% CI = 0.66–1.14, p = 0.321). We concluded that the −607A allele of the IL-18 gene promoter polymorphism may play a protective role against the progression of HIV-1 infection in this population.

Abstract
In leprosy, type 1 reaction (T1R) and type 2 reaction (T2R) are major causes of nerve injury and permanent disabilities. A previous study on plasma levels of 27 cytokines in patients with T1R or T2R and controls with nonreactional leprosy identified the gene for interleukin 6 (IL-6) as a candidate for genetic analysis. Two nested case-control studies were built from a cohort of 409 patients with leprosy from central Brazil, monitored for T1R and T2R. There was evidence for association between T2R and IL-6 tag single-nucleotide polymorphisms rs2069832 (P = .002), rs2069840 (P = .03), and rs2069845 (P = .04), with information on the entire IL-6 locus, as well as functional IL-6 variant rs1800795 (P = .005). Moreover, IL-6 plasma levels in patients with T2R correlated with IL-6 genotypes (P = .04). No association was found between IL-6 variants and T1R. Identifying genetic predictive factors for leprosy reactions may have a major impact on preventive strategies.
