Article Abstract

Background: Gout is caused by monosodium urate crystal-induced inflammation of the joints and periarticular tissues. Interleukin 10 (IL-10) is an important immunoregulatory cytokine, levels of which can be influenced by functional single-nucleotide polymorphisms in the promoter.

Objective: To investigate the association of -1082 G/A and -819 C/T polymorphisms in the IL-10 promoter with gout susceptibility in the Chinese Han male population.

Methods: A case-control study was performed in 302 patients and 284 controls. Genotyping of IL-10 -1082 G/A and -819 C/T polymorphisms was performed by DNA sequencing techniques. An association analysis was analyzed by the χ(2) test.

Results: No significant differences were found in -819T/C and -1082 A/G genotypic and allelic frequencies between gout cases and controls (for -819T/C, χ(2)=0.212, df=1, p=0.645 by genotype; χ(2)=0.079, df=1, p=0.779 by allele; for -1082 A/G, χ(2)=2.116, df=1, p=0.146 by genotype; χ(2)=1.854, df=1, p=0.173 by allele).

Conclusions: IL-10 -1082 G/A and -819 C/T polymorphisms may not be associated with susceptibility to gout and thus do not play a major role in the development of gout in the Chinese Han male population.

Background: Sickle cell disease (SCD) is characterised by chronic oxidative stress. However, there is limited information on how polymorphisms in cytokine genes influence oxidative stress in SCD patients. The study aimed to determine the effect of Interleukin gene (IL-10) and Tumor Necrosis Factor (TNF) polymorphisms on oxidative stress and cytokine levels in SCD patients from Mulago hospital.

Background: Febrile seizures (FS) were the most common seizure disorder in young children, with a notable prevalence in the Zhejiang Province region of China. The pathogenesis of FS involves both genetic and environmental factors, particularly the role of cytokines like Interleukin-10 (IL-10), an anti-inflammatory agent. This study examines the distribution of IL-10 gene polymorphisms and their association with FS susceptibility in children from Wenzhou, Zhejiang Province.

Background And Objective: Sexual dimorphism in drug efficacy, beyond pharmacokinetics (PK), remains underexplored. Significant sex differences exist in drug metabolism and adverse events, highlighting the need for personalized medicine. The objective of our study was to assess whether there are sex differences in the pharmacodynamic (PD) response to valproic acid (VPA) in photosensitive epilepsy, focusing on electroencephalographic (EEG) biomarkers (e.

Background: Single nucleotide polymorphisms (SNP) in genes encoding cytokines influence tuberculosis (TB) outcomes.

Objectives: To characterise genotypes of the SNPs IFN-gamma +874 T > A, TNF-alpha -308 G > A, IL-6 -174 G > C, IL-10 -1082A > G, TGF-beta codon 10 T > C, and TGF-beta codon 25 G > C in patients with pulmonary (PTB) and extrapulmonary TB (EPTB).

Methods: 82 PTB and 45 EPTB cases were compared, concerning genotype distribution of the mentioned SNPs, characterised via sequence-specific primer polymerase chain reaction (PCR).

The complex cytokine network plays an important role in disease susceptibility and development, therefore single-nucleotide polymorphisms (SNPs) in or near cytokine genes may be relevant to development of systemic sclerosis (SSc). We in this study investigated 22 SNPs in 13 cytokine genes of SSc patients, and their association with disease susceptibility. Twenty-three clinically diagnosed SSc patients were enrolled for this purpose along with 80 healthy volunteers for comparisons.
