[Associated factors for prediabetes in patients with human immunodeficiency virus]. / Factores asociados para prediabetes en pacientes con virus de inmunodeficiencia humana.

Introduction: HIV disease was transformed from a fatal condition to one with metabolic complications. In Mexico City, the associated factors for prediabetes in this population are unknown; investigating it is relevant to improve their quality of life. Objective: To determine the risk association factors for prediabetes in people living with HIV. Material and methods: Cross-analytical, retrospective study. Records of patients living with HIV were reviewed, exposure factors and fasting glucose concentration were recorded. Patients from 18 to 65 years of age were included, on co-formulated antiretroviral treatment, without adjustment of antiretroviral treatment in the last two years, with a BMI of 18.5-40 kg/m2. Results: 148 patients were included, 68 presented prediabetes. The factors with risk association that were identified are: age over 60 years (OR 9.48, 95% CI 1.68-40.13), treatment with Efavirenz/Tenofovir/Emtricitabine (OR 9.28, 95% CI 2.55-33.74) and treatment time antiretroviral older than 12 months (OR 2.53, 95% CI .912-7.041). Conclusion: The prevalence of prediabetes in people living with HIV is 46%. The main associated factor was the consumption of Atripla. This study has clinical relevance since it will allow the implementation of prevention, diagnosis and treatment strategies for prediabetes in order to reduce associated morbidity and mortality.

Introducción: la enfermedad por VIH ha pasado de ser un padecimiento mortal a uno con complicaciones metabólicas. En la Ciudad de México se desconocen los factores asociados para prediabetes en esta población, investigarlo es relevante para mejorar su calidad de vida. Objetivo: determinar los factores con asociación de riesgo para prediabetes en personas que viven con VIH. Material y métodos: estudio transversal-analítico, retrospectivo. Se revisaron expedientes de pacientes que viven con VIH, registrándose los factores de exposición y la concentración de glucosa en ayuno. Se incluyeron pacientes de 18 a 65 años, en tratamiento antirretroviral coformulado, sin ajuste de tratamiento antirretroviral en los últimos dos años, con IMC de 18.5-40 kg/m2. Resultados: se incluyeron 148 pacientes, 68 presentaron prediabetes. Los factores con asociación de riesgo que se identificaron son: edad mayor de 60 años (OR: 9.48, IC95%: 1.68-40.13), tratamiento con Efavirenz/Tenofovir/Emtricitabina (OR: 9.28, IC95%: 2.55-33.74) y tiempo de tratamiento antirretroviral mayor de 12 meses (OR: 2.53, IC95%: 0.912-7.041). Conclusión: la prevalencia de prediabetes en personas que viven con VIH es del 46%. El principal factor asociado fue el consumo de Atripla. Este estudio tiene relevancia clínica ya que permitirá implementar estrategias de prevención, diagnóstico y tratamiento de prediabetes con la finalidad de reducir la morbimortalidad asociada.

Pentoxifylline decreases serum LDH levels and increases lymphocyte count in COVID-19 patients: Results from an external pilot study.

We have previously hypothesized that pentoxifylline could be beneficial for the treatment of COVID-19 given its potential to restore the immune response equilibrium, reduce the impact of the disease on the endothelium and alveolar epithelial cells, and improve the circulatory function.Serum lactate dehydrogenase (LDH) and lymphocyte count are accessible biomarkers that correlate with the severity of COVID-19, the need for hospitalization, and mortality, reflecting the host immune response's contribution to the seriousness of SARS-CoV-2 infection. We carried out this external pilot study on 38 patients with moderate and severe COVID-19 to test the effect pentoxifylline on parameters such as LDH, lymphocyte count, days of hospitalization, mortality, and proportion of patients requiring intubation. Twenty-six patients were randomized to receive 400 mg of pentoxifylline t.i.d. plus standard therapy (pentoxifylline group), while the rest received the standard treatment (control group). Linear regression models were built for statistically significant parameters. Pentoxifylline treatment was associated with a 64.25% increase (CI95% 11.83, 116.68) in lymphocyte count and a 29.61% decrease (CI95% 15.11, 44.10) in serum LDH. Although a trend towards reduced days of hospitalization, mortality, and proportion of patients requiring intubation was observed, no statistically significant difference was found for these parameters. Our findings open the possibility of pentoxifylline being repositioned as a drug for COVID-19 treatment with the advantages of a proven safety profile, availability, and no risk of immunosuppression; however, this evidence needs to be confirmed in a pragmatic randomized controlled trial.
