Hepatitis C virus genotype and level of viraemia were determined in pretreatment sera from 65 Australian patients treated with interferon-alpha 2b (IFN-alpha 2b), 3 MU tiw for 6 months.
The results of this study suggest that vertically acquired HCV infection has a benign course in children, despite the presence of viraemia and persistent alterations in ALT levels.
Children infected with genotype 3 had the highest alanine aminotransferase levels and the highest rate of spontaneous viraemia clearance within the first three years of life (32% v 3% in children with genotype 1; p<0.001).
There was no relationship between T cell responses and the parameters of disease evolution as determined by ALT (serum alanine transaminase levels), and histologic hepatic damage (Metavir score A and F), but there was a positive relationship between the presence of a core-specific T cell responses and the viraemia.
A total of 55 patients were included.Group 1 consisted of 37 patients with low-level viraemia and high serum alanine aminotransferase (ALT) levels and further randomized to two groups: group 1a (n=19) patients received 1 year of lamivudine therapy and group 1b (n=18) patients were untreated controls.
Predictive factors of sustained response included the genotype (non-1 95% vs. 1 48%; P < 0.001), lower viraemia (503 917 +/- 553 230 vs. 901 393 +/- 548 267 copies/mL; P < 0.005), higher alanine aminotransferase levels (137 +/- 75 vs. 103 +/- 41 IU/L; P < 0.05) and a lower gamma-glutamyl transpeptidase/alanine aminotransferase ratio (0.30 +/- 0.23 vs. 0.49 +/- 0.39; P < 0.05).
There were no significant differences in gender, age, presence of hepatitis G virus, the occurrence of fulminant hepatitis, or in serum albumin, bilirubin or alanine aminotransferase levels (9/30 vs 35/134) between patients with or without TTV viraemia.
Sixteen subjects were defined as sustained responders (SR), who showed sustained loss of viraemia with normalized alanine aminotransferase values for at least 6 months of follow-up after completion of therapy.
The aim of this study was to evaluate the ability to spontaneously control viral replication during analytical treatment interruption (ATI) in adults with chronic HIV-1 infection, on ART, with suppressed viraemia for >10 years and with a low reservoir.

Patients with HIV suppressed viraemia (plasma viral load <50 copies/mL for 12 months) under ART who had switched to darunavir/ritonavir monotherapy at 600/100 mg/day between 2013 and 2015 were included in this observational 48 week single-centre study.

Optimal timing of viral load monitoring during pregnancy to predict viraemia at delivery in HIV-infected women initiating ART in South Africa: a simulation study.
Mean plasma mtDNA levels were 217 ± 656 copies/μL for naive (31.9%) and 364 ± 939 copies/μL for HIV-infected patients receiving ART and with suppressed viraemia (P = 0.043).
