Incidence and Severity of SARS-CoV-2 Infection in HIV-Infected Individuals During the First Year of the Pandemic.

BACKGROUND: We aim to investigate the infection rate, the clinical characteristics and outcomes of COVID-19-disease in a cohort of people living with HIV in Madrid (Spain), during the first year of pandemics. SETTING: Observational single-center study, in which we included all HIV-infected patients (aged ≥ 18 years) with laboratory-confirmed severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection as of February 28, 2021, at the Hospital Universitario 12 de Octubre. METHODS: Confirmed disease was defined as any patient with a positive antigen test, reverse transcriptase polymerase chain reaction, or serology for SARS-CoV-2. We compared the characteristics of patients with mild disease (asymptomatic included) with those with moderate or severe disease (requiring admission). RESULTS: Of 2344 HIV-infected patients, 158 (82.9% male; median age, 46.5 years) were diagnosed with SARS-CoV-2 (infection rate, 6.74%; 95% confidence interval, 5.79 to 7.83). Thirty-nine individuals (24.7%) had moderate or severe disease, 43.7% had mild disease, and 31.6% were asymptomatic. Hypertension (23.4%) and obesity (15.8%) were the most prevalent comorbidities; 12.7% had at least 2 comorbidities. One hundred forty-five patients (97.3%) had RNA-HIV viral load of <50 copies per milliliter, and only 3 had CD4 cell count of <200 cells per cubic millimeter before infection. Of those admitted to hospital, 59% required oxygen support and 15.4%, invasive mechanical ventilation. Five patients died. None of the patient taking tenofovir-disoproxil-fumarate required admission. In the multivariate analysis, age remained as the only independent factor for moderate-severe disease (odds ratio, 1.09; 95% confidence interval 1.04 to 1.14; P < 0.001). CONCLUSIONS: People living with HIV are at risk of severe SARS-CoV-2 infection. Age was the only variable with an independent association with moderate-severe disease, after adjusting by comorbidities and other factors.

Use of methotrexate for leprosy reactions. Experience of a referral center and systematic review of the literature.

BACKGROUND: Patients with leprosy can present with systemic inflammatory complications called leprosy reactions (LR), which can be severe and cause a loss of nerve function. The treatment of choice is prolonged corticosteroid therapy, frequently associated with severe side effects. We have used methotrexate as a corticosteroid-sparing regimen with good results. METHODS: To evaluate the role of methotrexate in managing LR, we performed a systematic review of the literature including our cases. We evaluated studies, prospective and retrospective, in both adults and children, which included any dose/regimen of methotrexate for the treatment of LR type 1 or 2. RESULTS: The systematic search revealed 261 records that yield 21 patients including our 3 cases (19 adults/two children), who were treated with methotrexate for LR type 1 and 2. There were 14 males. Median age was 35 years (P25-P75 28 to 52). Patients showed lepromatous (7), borderline lepromatous (9) or borderline tuberculoid (3) leprosy, among the 19 cases in which the type of leprosy was specified. As for the type of LR, 15 patients showed erythema nodosum leprosum (ENL), five showed LR type 1 and one showed polyarthritis and previous ENL. Methotrexate at weekly doses ranging from 7.5 mg to 20 mg (median 15 mg per week), typically administered with low-dose corticosteroids, was effective and safe as a corticosteroid-sparing agent. CONCLUSIONS: Methotrexate could be a suitable ancillary treatment or alternative to corticosteroids, especially in populations who are more prone to its adverse events. However, this evidence is based only on case reports and short clinical series.
