Hepatitis C virus (HCV) infection is more prevalent in people living with HIV‐AIDS (PLHA) and portends a poorer prognosis. Pharmacokinetic studies suggest the absence of significant interaction between velpatasvir and dolutegravir which has been recently recommended as part of preferred first‐line antiretroviral therapy (ART) regimens by WHO. However, clinical data on the use of velpatasvir‐based regimen in PLHA taking dolutegavir is lacking. Hence, we aimed to assess the efficacy and safety of sofosbuvir and velpatasvir (SOF + VEL) in HCV and HIV coinfected patients on dolutegravir‐based ART. Forty‐five consecutive PLHA with HCV coinfection on dolutegravir‐based ART were prospectively enrolled. All patients were treated SOF + VEL for 12 weeks. Complete haemogram, liver and renal function tests were assessed at baseline, 4 weeks and at end of treatment. Sustained virological response (SVR) was assessed at 12 weeks after end of treatment. The majority were males (95.5%) with a mean age of 32.8 ± 12.3 years. Cirrhosis was present in 6 (13.3%) patients. All patients completed 12 weeks of therapy with SOF + VEL, but SVR could not be assessed in two patients. Forty‐two (97.7%) of the remaining 43 patients attained SVR‐12. SVR‐12 rate was 97.7% and 93.3% by per protocol and intention to treat analysis, respectively. No grade III/IV adverse events were reported, and there was no worsening of blood counts, liver or renal function test parameters. The pan‐genotypic regimen of SOF + VEL is safe and effective in PLHA with HCV coinfection who are on dolutegravir‐based ART. [ABSTRACT FROM AUTHOR]

Summary: Treatment of Hepatitis C virus (HCV) in patients with severe renal insufficiency is cumbersome as sofosbuvir is mainly excreted by the kidneys. There is paucity of data on the use of sofosbuvir and NS5A inhibitors in these patients. We hereby report our experience of treating chronic hepatitis C in patients with severe renal insufficiency with full dose sofosbuvir and NS5A inhibitors. Forty‐seven patients with severe renal insufficiency (on dialysis n = 39, predialysis n = 8) with HCV infection were treated between December 2015‐August 2017 with full dose sofosbuvir with ledipasvir or daclatasvir for 12/24 weeks depending on the genotype and the presence or absence of cirrhosis. The distribution of HCV genotype was genotype 1 in 32 (68.1%), genotype 3 in 13 (27.7%) and 4 in 2 (4.3%) patients. Among 12 (25.5%) patients with cirrhosis, 7 (14.9%) were decompensated with ascites. All patients had end of treatment response, and sustained viral response at 12 weeks was achieved in 45 (95.7%) patients. There was significant improvement in liver stiffness at 3 months after treatment (8.8 (3.8‐42) to 7.1 (3.3‐24.1) kPa; (P = 0.047)). There was no change in haemoglobin and eGFR with treatment in predialysis group (haemoglobin‐ 10.2 ± 1.5 g/dL vs 9.6 ± 1.3 g/dL, P = 0.44; eGFR‐ 19.8 ± 9.4 mL/min vs 17.9 ± 8.5 mL/min, P = 0.67). Therapy was very well accepted. Full dose sofosbuvir with NS5A inhibitors is a well tolerated and effective therapy for HCV infection in severe renal insufficiency. [ABSTRACT FROM AUTHOR]
