Aim Of The Study: To evaluate the role of potential genetic predictors -308G/A TNF-α and -403G/A CCL5 in treatment for HCV 1 genotype.
Material And Methods: Treatment results of 130 patients with chronic hepatitis C 1 genotype according to different genotypes of IL28B, CCL5, and TNF-α were analysed using multiple logistic regression.
Results: IL28B genotypes CC/CT/TT were found in 27 (20.8%), 74 (56.9%), and 29 (22.3%) patients. Genotypes GG/GA/AA of -308G/A TNF-α were revealed in 98 (75.4%), 30 (23.1%), and 2 (1.5%) patients. Genotypes GG/GA/AA of -403G/A CCL5 were revealed in 86 (66.2%), 39 (30%), and 5 (3.8%) patients, respectively. The previously known effect of IL28B was observed. IL28B TT genotype decreased end of treatment response (EOTR) rates by a factor of 29.0 (95% CI: 6.4-183). The combination of CCL5 GG and IL28B CT genotypes increased the risk of failure to achieve EOTR by a factor of 28.5 (95% CI: 7.2-160). Genotypes GA and AA of TNF-α (-308) G/A SNP increased the risk of relapse in patients who achieved EOTR (OR = 9.4; 95% CI: 2.4-48).
Conclusions: Practitioners may benefit from using these predictors when considering indications for the antiviral therapy and deciding on the treatment regimen.

Introduction: This study evaluated the influence of interleukin-10 (IL10) gene -1082G>A and tumor necrosis factor-alpha (TNF) gene -308G>A polymorphisms in the donor and recipients on the acute rejection (AR) episodes and delayed graft function (DGF) in kidney transplant recipients.
Materials And Methods: The IL10 -1082G>A and TNF -308G>A polymorphisms were determined in 100 kidney allograft recipients and their donors using the polymerase chain reaction-amplification refractory mutation system polymerase chain reaction-restriction fragment length polymorphism methods. Transplantation outcomes were determined in terms of AR and DGF criteria.

Article Synopsis
- * Researchers analyzed blood samples from 172 RA patients and 160 healthy controls to look for variations in these genes using PCR-RFLP techniques.
- * Results indicate that the TNF-α 308AA genotype and the TNFRII 196M/R polymorphism are connected to higher susceptibility to RA, while the TNF-α 308GG genotype is linked to greater disease severity.
