Aim of the studyTo evaluate the role of potential genetic predictors –308G/A TNF-α and –403G/A CCL5 in treatment for HCV 1 genotype.Material and methodsTreatment 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.ResultsIL28B 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).ConclusionsPractitioners may benefit from using these predictors when considering indications for the antiviral therapy and deciding on the treatment regimen.
