Abstract Background The efficacy of screening programs to prevent anal cancer in persons with human immunodeficiency virus 1 (HIV-1) is unclear. Methods To examine the impact of a screening program to detect anal cancer precursors on the incidence of cases of invasive anal squamous-cell carcinoma (IASCC) in persons with HIV-1, we performed a single-center, retrospective analysis of a prospective cohort of outpatients with HIV-1 attending a reference HIV unit from January 2005 onward. All participants were invited to participate in a continued structured screening program for anal cancer prevention. We estimated the incidence of IASCC and performed a comparative analysis between subjects enrolled in the screening program (screening group) and those who declined to participate (nonscreening group). To reduce any selection bias, a propensity score analysis was applied. Results We included 3111 persons with HIV-1 (1596 men-who-have-sex-with-men [MSM], 888 men-who-have-sex-with-women [MSW], 627 women; mean age, 41 years), with a median follow-up of 4.7 years (14 595 patient-years of follow-up); 1691 (54%) participated in the screening program. Ten patients were diagnosed with IASCC: 2 (MSM) in the screening group and 8 (4 MSM, 2 MSW, and 2 women) in the nonscreening group. The incidence rates of IASCC were 21.9 (95% confidence interval [CI], 2.7–70.3) and 107.0 (95% CI, 46.2–202.0) per 100 000 person-years, respectively. After a propensity score adjustment, the difference was significant in favor of the screening group (hazard ratio, 0.17; 95% CI, .03–.86). Conclusions The number of cases of IASCC was significantly lower in persons with HIV engaged in an anal cytology screening program. These results should be validated in a randomized clinical trial.

Background Sarcopenia is a geriatric syndrome that leads to a loss of functionality and mortality. Methods We assessed the prevalence of sarcopenia in HIV-infected patients attended in our HIV Unit who had at least two DXA scans from 2000 to 2016 (1,720 DXA scans from 860 individuals). Sarcopenia was determinate according to appendicular skeletal muscle mass index (ASM) calculated as the ratio between skeletal muscle mass index (SMI) by DXA and height2 (kg/m2). We stratified patients by gender and age (<40, 41-50, and >50 years) and according to the interval between DXAs (≤3, 3-7, 7-10, >10 years). The statistical analysis was performed using SPSS version 19. Results Median (IQR) age was 52 (47; 57) years, and 76% were male. The median (IQR) time with HIV infection was 8 (3; 15) years. The prevalence of sarcopenia was 25.7% (95% CI, 22.8-28.7), more prevalent in those aged >50 years (27.8%). Stratifying by gender, 43% of women aged >50 years presented sarcopenia compared with 8.8% of men. The frequency of sarcopenia increased from 37.6% to 49.4% when interval between DXA was 7-10 years (n=109), significantly higher in women than in men (p=0.016). In addition to the traditional risk factors, time with HIV infection was associated with sarcopenia [RR 1.780 (95% CI, 1.314-2.411), p=0.001]. Conclusion The prevalence and progression of sarcopenia in HIV-infected patients were high, mainly among women. Further studies are necessary to assess the best approaches to prevent this condition and its consequences.

Virologically suppressed HIV-infected patients showed similar arterial elasticity to non-HIV-infected patients. HIV-related conditions were not associated with arterial stiffness, probably because of the good immunologic and virological status of this group. However, high diastolic pressure at the time of PWV and high levels of triglycerides were associated risk factors.

The epidemiology and 12-month mortality of HIV-1-infected subjects with PCP have changed significantly in the late-HAART era, while mortality during hospital stay has remained unchanged. HIV diagnosed individuals lost to follow-up in care have emerged as the main driver of PCP in developed countries. Like HIV late presenters, they are more likely to have AIDS-defining illnesses, to be hospitalized, and to die. This finding has important implications for the design of better strategies to retain HIV-1-infected individuals in care.
