Analysis of blood testing indicators in HIV patients co-infected with different genotypes of HCV in Kunming area of Yunnan Province
Objective To understand the genotyping of human immunodeficiency virus(HIV)co-infected hepatitis C virus(HCV)patients in Yunnan Province,and to analyze the differences in viral load,biochemical indicators,and blood routine indicators among different genotypes,in order to provide a laboratory basis for the diagnosis and clinical treatment of HIV/HCV co-infected patients.Methods From November 2022 to June 2023,the serum samples and basic information of patients diagnosed with HIV/HCV co-infection were collected in the antiviral outpatient clinic of Yunnan Provincial Hospital of Infectious Diseases.The HCV viral load was detected by one-step qRT-PCR amplification,the positive samples were sequenced,and genotyping was determined based on NS5 gene sequence.The differences in biochemical and blood routine indexes between HIV patients co-infected with different HCV genotypes and low/high viral loads were analyzed.Results A total of 126 HIV/HCV co-infected patients were collected,including 20 HCV genotype 1(15.9％),91 HCV genotype 3(72.2％),and 15 HCV genotype 6(11.9％).The maximum and minimum viral load of the three HCV genotypes were as follows:HCV type 1(1.0×108,4.8×104 IU/mL),HCV type 3(2.2×108,2.9×102 IU/mL),and HCV type 6(8.1×107,6.8×104 IU/mL).The results showed that there was no significant difference between HIV co-infection with different genotypes of HCV and three HIV treatment schemes,including nucleoside reverse transcriptase inhibitors+integrase strand transfer inhibitors(NRTIs+INSTIs),nucleoside reverse transcriptase inhibitors+non-nucleoside reverse transcriptase inhibitors(NRTIs+NNRTIs)and nucleoside reverse transcriptase inhibitors+protease inhibitor(NRTIs+PLs),and the viral load of patients(P＞0.05).The analysis of biochemical indexes such as total bilirubin(TBIL),direct bilirubin(DBIL),alanine aminotransferase(ALT),aspartate aminotransferase(AST),creatinine(CREA),and blood routine indexes such as white blood cell(WBC),red blood cell(RBC),hemoglobin(HGB),platelet(PLT),mean corpuscular hemoglobin(MCH)and mean corpuscular hemoglobin concentration(MCHC)among different HCV genotypes and low/high viral loads showed that there was no significant difference in biochemical indexes and blood routine indexes between low/high viral loads of HIV co-infected HCV patients(P＞0.05);however,the biochemical indicators TBIL,IBIL and MCHC were significantly different statistically between patients with genotype 3 HCV infection and those with genotype 1 HCV infection(P＜0.05),while other biochemical and blood routine indexes were not statistically different among different HCV genotypes(P＞0.05).Conclusions There are six subtypes of HCV co-infection in HIV patients in Kunming,Yunnan Province,including three genes of genotype 1,3,and 6.Among them,genotype 3 HCV is the main prevalent genetic virus among HIV co-infected populations.The TBIL,IBIL and MCHC values of HIV patients co-infected with HCV type 3 are different from those infected with HCV type 1.
