Interleukin-10 gene promoter polymorphism in Polish rheumatoid arthritis patients

Interleukin (IL)-10 is an important multifunctional cytokine with both anti-inflammatory and immunoregulatory effects in rheumatoid arthritis (RA). In the present study, we evaluated the frequency and potential impact of IL-10 promoter polymorphisms on susceptibility to and severity of RA in Polish in – patients with a high disease activity (mean DAS 28 C-reactive protein 5.25). DNA was obtained from 244 RA patients and 106 healthy controls. The −592C/A and −1082G/A IL-10 gene polymorphisms were amplified by polymerase chain reaction with restriction endonuclease mapping. The frequency of the IL-10-592CA, -592AA genotypes (respectively: 30% vs 5% and 7% vs 0%) and allele −592A (37% vs 5%) were significantly higher in RA patients as compared with a control group. We did not find any association of the IL-10-592C/A genotype distribution with disease parameters, except for an increased ESR (erythrocyte sedimentation rate) in patients with the −592CC genotype as compared with those with −592CA or −592AA genotypes (P = 0.01). The frequency of the IL-10-1082GG genotype was lower (P = 0.0001), and that of the IL-10-1082GA genotype was higher (P = 0.009) in RA patients comparing with the control group. In RA patients with −1082GA or −1082AA genotypes the time duration of the disease (P = 0.03), Health Assessment Questionnaire (HAQ) Score (P = 0.04) and PLT count (P = 0.001) were significantly increased as compared with subjects with −1082GG genotype. Presented findings indicate that IL-10-592C/A and IL-10-1082G/A polymorphisms may be considered genetic risk factors for RA susceptibility and severity.     

Interferon-gamma +874 T/A and interleukin-10 -1082 A/G single nucleotide polymorphism in Egyptian children with tuberculosis

The aim was to investigate the association of interferon-gamma (IFN-γ) +874 T/A and interleukin-10 (IL-10)-1082 A/G single nucleotide polymorphisms with tuberculous infection and post-BCG lymphadenitis in Egyptian children. IFN-γ +874 T/A and IL-10 -1082 A/G polymorphism detection by amplification refractory mutation system technique was carried out for 110 patients with TB, 40 patients with post-BCG lymphadenitis and 118 healthy controls. IFN-γ +874 A allele was higher in TB and post-BCG patients than those in healthy controls (Pc=0.006 and 0.002, respectively). IFN-γ +874 genotype AA was significantly higher in patients with TB than that in control (Pc=0.015), in extrapulmonary than patients with pulmonary TB (PTB) (Pc=0.009), and young children with TB below 5 years (Pc=0.024). No statistically significant differences were observed between patients with TB and controls for the frequency of IL-10(-1082) alleles or genotypes (P>0.05); however, a statistically significant difference in the frequency of IL-10 (-1082) GG genotype was found between patients with pulmonary and extrapulmonary TB (Pc=0.003). Low producer IFN-γ +874 A/A genotype is associated with post-BCG lymphadenitis and TB disease especially in younger children below 5 years. IL-10-1082 G/G genotype did not exhibit significant association except for increased GG frequency in PTB. Both cytokine polymorphisms have no relation to tuberculin reaction in patients with TB.

Interleukin-10 -1082A/G polymorphism is associated with the development of acute pancreatitis in a Chinese population

We conducted a case-control study to investigate the association between IL-10 gene polymorphism (-1082A/G, -819T/C, and -592A/C) and risk of acute pancreatitis in a Chinese population. A total of 240 patients with proven acute pancreatitis and 240 control subjects were collected between May 2012 and January 2015. Genotyping of the IL-10-1082A/G, -819T/C, and -592A/C gene polymorphisms was conducted by using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. By univariate logistic regression analysis, patients with acute pancreatitis were more likely to have higher BMI (OR=2.12, 95% CI=1.45-3.12; P<0.001) and have a habit of alcohol drinking (OR=2.01, 95% CI=1.37-2.95; P<0.001). There were significant differences in the genotype distributions of IL-10-1082A/G between patients with acute pancreatitis and control subjects (χ²=9.97, P=0.007). By multiple logistic regression analysis, we found that individuals with the GG genotype of IL-10-1082A/G were associated with an increased risk of acute pancreatitis when compared with the AA genotype (OR=2.32, 95% CI=1.20-4.59; P=0.007). In dominant and recessive models, the IL-10-1082A/G gene polymorphism was significantly correlated with an elevated risk of acute pancreatitis, and the adjusted Ors (95% CI) were 1.50 (1.03-2.20) and 1.99 (1.06-3.79), respectively. However, no significant different was found between IL-10-819T/C and -592A/C gene polymorphisms and susceptibility to acute pancreatitis. In conclusion, we suggest that IL-10-1082A/G gene polymorphisms contribute to the development of acute pancreatitis in codominant, dominant and recessive models.     

Investigation on the association between inerleukin-10 -592C/A, 819C/T and -1082A/G gene polymorphisms and development of diabetic nephrophathy

We conducted a case-control study to investigate the association between interleukin (IL)-10-592C/A, -819C/T and -1082A/G polymorphisms and susceptibility to diabetic nephropathy. A hospital-based case-control study was taken in our study. A total of 172 patients with proven type 2 diabetes mellitus and 344 controls were recruited from the First Affiliated Hospital of Xinxiang Medical University between March 2012 and October 2014. Genotyping of IL-10 -592C/A, -819C/T and -1082A/G polymorphisms was done by done by PCR-RFLP methods. By the χ² test, the distributions of the GG, GA and AA genotypes in IL-10 -1082A/G were significantly different between patients with diabetic nephropathy and control subjects (χ² = 8.09, P = 0.02). By conditional logistic regression analysis, we found that the AA genotype of IL-10 -1082A/G was associated with an elevated risk of diabetic nephropathy compared to the GG genotype in codominant model, and the adjusted OR (95% CI) was 2.38 (1.23-4.57). In dominant model, the GA+AA genotype was associated with a significantly increased risk of diabetic nephropathy compared to the GG genotype in dominant model (OR = 1.47, 95% CI = 1.05-2.16). In recessive model, the AA genotype could influence the susceptibility to diabetic nephropathy when compared with the GG+GA in recessive model (OR = 2.08, 95% CI = 1.12-3.85). In conclusion, we suggested that IL-10 -1082A/G gene polymorphism was correlated with development of diabetic nephropathy, but no association was observed between IL-10 -819T/C and -592A/C and risk of diabetic nephropathy.
