ABSTRACT
OBJECTIVES: Dolutegravir + lamivudine (DTG + 3TC) is a first-line regimen for people with HIV. However, there are still concerns about its efficacy in people with tuberculosis (TB)/HIV due to the lack of available evidence and drug-drug interaction with rifampicin. METHODS: A single-centre retrospective observational case series was conducted in Guangxi Zhuang Autonomous Region, China. We included all people with TB/HIV on combined use of once-daily (q.d.) dosing DTG + 3TC and rifampicin (RIF)-containing anti-TB regimens between 2020 and 2022. HIV-RNA, CD4 cell counts were collected and analysed. RESULTS: In all, 21 people with HIV (PWH) were included in this study. All the PWH were treatment-naïve and told to take DTG + 3TC q.d. with food. The median age was 53 years, and 71.43% were male. A total of 71.43% PWH had baseline viral load (VL) > 100 000 copies/mL, and 33.33% had baseline VL greater than 500 000 copies/mL. Only one PWH had CD4 cell count greater than 200 cells/µL, and the median CD4 count was 20 cells/µL. A total of 16 PWH started DTG + 3TC after initiation of the RIF-based anti-TB regimen, and the other five PWH initiated DTG + 3TC before the treatment of TB. All the PWH had at least 24 weeks of follow-up visits and all of the TB treatments were successful. A total of 20 PWH (95.24%) achieved viral suppression (VL <50 copies/mL). All detected viral loads between weeks 24 and 48 were less than 200 copies/mL. Among the PWH who started DTG + 3TC after the initiation of RIF-based anti-TB regimen, all achieved viral suppression by week 24 except the non-suppressed PWH. CD4 counts were greatly improved after antiretroviral treatment: the median CD4 counts were raised from 20 to 171 cells/µL at week 48. No serious adverse events were reported. CONCLUSIONS: This case series preliminarily validates the efficacy of DTG + 3TC q.d. with food when combined with RIF-based anti-TB regimens in people with TB/HIV.
ABSTRACT
Background: The direct-acting antiviral agents (DAAs) have revolutionized the treatment of Hepatitis C Virus (HCV) infection. However, a simple and feasible treatment strategy with high efficacy and safety for HCV in patients coinfected with Human Immunodeficiency Virus (HIV) remains an unmet medical need, especially in areas with limited health resource. This study aims to assess the efficacy and safety of 12 weeks of treatment with sofosbuvir and velpatasvir in patients with chronic HCV/HIV-1 coinfection. Methods: We conducted a multicenter, single-arm, open-label study in China, which involved chronic HCV/HIV-1 coinfected patients who are receiving an antiretroviral regimen of a combination tablet consisting of elvitegravir, cobicistat, emtricitabine, tenofovir alafenamide, (EVG/c/FTC/TAF) once daily. Patients with liver cirrhosis or experienced to DAAs treatment were excluded. All patients received combined sofosbuvir (400 mg) and velpatasvir (100 mg) tablet once daily for 12 weeks regardless of HCV genotype. The primary efficacy endpoint was sustained virologic response, defined as HCV RNA <15 IU/mL at 12 weeks after completion of treatment (SVR12). The primary safety endpoint was the proportion of patients who prematurely discontinued treatment because of adverse events. Safety and efficacy data were analyzed with an intention-to-treat (ITT) population (last observation carried forward) and per-protocol (PP) population. This trial is registered on ChiCTR.org.cn with number being ChiCTR1800020246. Findings: Of the 243 patients enrolled, 78% were male, 9% had been previously treated for HCV with interferon, and none had pre-defined cirrhosis, although 8% had Fibrosis 4 score (FIB-4) >3.25. A total of 233 patients completed 12-week post-treatment follow-up. Overall, 227/233 patients (97%) achieved SVR12: 100% (63/63) in those with HCV genotype 1, 67% (2/3) in those with genotype 2, 95% (84/88) in those with genotype 3, 99% (78/79) in those with genotype 6. Rates of SVR12 were lower among those with baseline FIB-4 >3.25 than those without (78% [14/18] vs. 99% [211/212], P < 0.001). HIV-1 suppression was not compromised. The most common adverse events were upper respiratory tract infection (5%), cough (3%), abnormal renal function (2%), abnormal liver function (2%), constipation (2%), urinary tract infection (2%) and sleep disorders (2%). No participant discontinued treatment because of adverse events or death. Interpretation: Twelve weeks of treatment with sofosbuvir/velpatasvir provide high rates of SVR and is well-tolerated in patients coinfected with HIV-1 and HCV regardless of HCV genotypes. Non-invasive liver fibrosis score may help to further distinguish patients at greater likelihood of a suboptimal response.

ABSTRACT
BACKGROUND: There is a high prevalence of anemia among people living with HIV in Guangxi, China. Therefore, we investigated anemia and opportunistic infections in hospitalized people living with HIV and explored the risk factors related to anemia in people living with HIV to actively prevent anemia in people living with HIV. METHODS: We retrospectively studied people living with HIV admitted to Guangxi Chest Hospital from June 2016 to October 2021. Detailed information on the sociodemographic and clinical features of the participants was collected. The X2 test was used to compare the prevalence between the anemic and non-anemic groups. The logistic regression analysis was applied to exclude confounding factors and identify factors related to anemia. RESULTS: Among 5645 patients with HIV, 1525 (27.02%) had anemia. The overall prevalence of mild, moderate, and severe anemia was 4.66%, 14.08%, and 8.27%, respectively. The factors significantly related to increased risk of anemia were CD4 count < 50 cells/µl (aOR = 2.221, 95% CI = [1.775, 2.779]), CD4 count 50-199 cells/µl (aOR = 1.659, 95% CI = [1.327, 2. 073]), female (aOR = 1.644, 95% CI = [1.436, 1.881]) co-infected with HCV (aOR = 1.465, 95% CI = [1.071, 2.002]), PM (aOR = 2.356, 95% CI = [1.950, 2.849]), or TB (aOR = 1.198, 95% CI = [1.053, 1.365]). CONCLUSIONS: Within Guangxi of China, 27.02% of hospitalized people living with HIV presented with anemia. Most patients with anemia were in the mild to moderate stage. The low CD4 count, female gender, and concomitant infection with Penicillium marneffei, Hepatitis C virus, or Tuberculosis were independent correlates of anemia. Thus, these findings would be helpful to clinicians in preventing and intervening in anemia in people living with HIV.
