We describe the first 25 persons with HIV diagnosed with human monkeypox virus (MPXV) in our hospital in an ongoing outbreak in Spain. Proctitis was the predominant finding in 52%, and MPXV DNA was detected in rectal swabs from 90%. Proctitis and demonstration of MPXV in rectal swabs support the sexual transmission of MPXV.

Multiple strategies have been utilised to reduce the incidence of HIV, including PrEP and rapid antiretroviral therapy initiation. The study objectives were to evaluate the efficacy, safety, satisfaction, treatment adherence, and system retention obtained with rapid initiation of bictegravir/emtricitabine/tenofovir alafenamide (BIC/FTC/TAF) in naïve patients. This phase IV, multicenter, open-label, single-arm, 48-week clinical trial enrolled patients between January 2020 and June 2022. Adherence to treatment was evaluated with the SMAQ questionnaire and patient satisfaction with the EQ-5D. Two hundred eight participants were enrolled with mean age of 35.6 years; 87.6% were males; mean CD4 count was 393.5 cells/uL (100 000 cop/mL in 43.3%); 22.6% had AIDS, and 4.3% were coinfected with HBV. BIC/FTC/TAF was initiated on the day of their first visit to the HIV specialist in 98.6% of participants, and 9.6% were lost to follow-up. The efficacy at week 48 was 84.1 % by intention-to- treat (ITT), 94.6% by modified ITT, and 98.3% by per protocol analysis. The regimen was discontinued in two subjects (0.9%) during week 1 for grade 3 adverse events. Treatment adherence (weeks 4 [90%, IQR: 80-99%] vs. 48 [90%, IQR: 80-95%; P = 0.49]) and patient satisfaction (weeks 4 [90%, IQR: 80-99%] vs. 48 [90%, IQR: 80-95 P = 0.49]) rates were very high over the 48- week study period. BIC/FTC/TAF is an appropriate option for rapid ART initiation in naïve HIV patients, offering high efficacy, safety, durability, treatment adherence, retention in the healthcare system, and patient satisfaction. Number Clinical Trial registration: NCT06177574.

Objectives: There are scarce data on the combination of dolutegravir (DTG) plus rilpivirine (RPV) in the real world, including patients with hepatitis C virus (HCV) coinfection, toxicity or previous failure, or at risk for severe drug–drug interactions (DDIs). Methods: Prospective cohort study of virologically suppressed HIV-1 infected patients, without resistance to DTG or RPV, switched to this dual regimen because of toxicity or risk of DDIs (NCT02491242). Results: Overall, 102 patients (mean age 54 years, 28% women) were included. Fifty-seven were coinfected with HCV (fibrosis grade 4 in 27 cases, 1 liver transplantation). Seven patients had chronic kidney disease (1 renal transplantation). At week 48, only 1 virologic failure occurred (<1%), and 6 patients (6%) left the regimen (3 with central nervous system adverse events, 1 each due to pregnancy, metformin interaction, and lost to follow up). Thus, the overall treatment success rates were 93% (95% CI, 88%–98%; ITT-e, snapshot analysis) and 96% (95% CI, 92%–99%; per protocol analysis). The CD4/CD8 ratio increased slightly (median, +0.03). Triglycerides levels improved significantly (−18.8%, p < 0.01). The creatinine-based estimated glomerular filtration rate decreased by a mean of −8.4 ml/min/1.73 m², but tubular renal parameters improved. A paired dual X-ray absorptiometry scan showed a mild improvement in spine (mean, +1.15%; −0.57 to +3.3%) and in femoral neck bone mineral density (mean, +0.4%; −3.3% to +2.57%). Conclusions: In the clinical setting, switching to the combination of DTG plus rilpivirine in virologically suppressed HIV-1 patients is effective and safe, and improves lipid, renal and bone evolution.

We identify factors associated with the normalization of the CD4+:CD8+ T cell ratio among UK Collaborative HIV Cohort study participants, and describe the association of the CD4+ and CD8+ T cell counts and the CD4+:CD8+ T cell ratio, with the risk of new AIDS events among individuals who achieve a suppressed viral load. Participants initiating combination antiretroviral therapy (cART) after 2006 with a CD4+:CD8+ T cell ratio 500 vs. ≤200 cells/mm ³ , adjusted hazard ratio (95% confidence interval): 7.93 (6.97–9.01)], low CD8+ T cell count [>1,150 vs. ≤500 cells/mm ³ : 0.18 (0.16–0.21)], and low CD4+:CD8+ T cell ratio [>0.8 vs. 500 vs. ≤200 cells/mm ³ : adjusted rate ratio 0.24 (0.16–0.34)] and CD4+:CD8+ T cell ratio [>0.8 vs. <0.2: 0.33 (0.21–0.52)] were independently associated with a new AIDS event. One third of study participants experienced ratio normalization after starting cART. CD4+ T cell count and CD4+:CD8+ T cell ratio are both individually associated with ratio normalization and the development of new AIDS events after cART.
