RESUMO
Background & objective: Nonalcoholic fatty liver disease (NAFLD) is highly prevalent in people living with HIV (PLWH) and the expression of some microRNAs could be useful as biomarkers for the diagnosis of NAFLD. The aim of this study was to identify patterns of differential expression of microRNAs in PLWH and assess their diagnostic value for NALFD. Methods: A discovery case-control study with PLWH was carried out. The expression of miRNAs was determined using HTG EdgeSeq technology. Cases were defined as patients with severe NAFLD and controls as patients without NAFLD, characterized using the controlled attenuation parameter (CAP). Cases and controls were matched 1:1 for age, sex, BMI, CD4+ lymphocyte count, active HCV infection, and ART regimen. Results: Serum 2,083 simultaneous microRNA transcripts were analyzed using HTG technology and compared between cases and controls. Forty-five patients, 23 cases, and 22 controls were included in the study. In the analysis of the expression pattern of the 2,083 microRNAs, no differential expression patterns were found between both groups of patients included in the study. Conclusion: Analysis of the microRNA transcriptome profile of nonobese PLWH with severe NAFLD did not appear to differ from that of patients without NAFLD. Thus, microRNA might not serve as a proper biomarker for predicting severe NALFD in this population.

OBJECTIVES: To evaluate the effect of the interleukin 28B (IL-28B) genotype on hepatitis C virus (HCV) viral kinetics in the first 4 weeks from start of treatment with pegylated interferon plus ribavirin (PEG-IFN/RBV) in HIV/HCV co-infected patients. METHODS: HIV/HCV co-infected patients naive to PEG-IFN/RBV treatment were enrolled in a prospective study. HCV RNA plasma viral loads were measured at baseline and at weeks 1, 2 and 4 after commencement of treatment. Patients were grouped by HCV genotype (genotype 1/4 versus 3) and by IL-28B genotype (CC versus non-CC). Differences in viral load reduction were evaluated by IL-28B genotype between baseline, week 1, week 2 and week 4. RESULTS: One hundred and nineteen HIV/HCV patients were included in the study. HCV patients with genotype 1/4 and bearing the IL-28 CC genotype showed the greatest reductions in HCV RNA plasma levels between baseline and weeks 1 (B-1), 2 (B-2) and 4 (B-4) than did those with non-CC genotypes (B-1: 1.06 ± 0.89 versus 0.48 ± 0.48 log IU/mL, P = 0.009; B-2: 1.36 ± 0.72 versus 0.77 ± 0.66 log IU/mL, P = 0.01; and B-4: 1.91 ± 0.64 versus 1.38 ± 0.96 log IU/mL, P = 0.03). However, differences between weeks 1 and 2 (W1-2) and between weeks 2 and 4 (W2-4) were not associated with the IL-28B genotype (W1-2: CC 0.48 ± 0.42 versus non-CC 0.38 ± 0.38 log IU/mL, P = 0.62; W2-4: CC 0.32 ± 0.23 versus non-CC 0.39 ± 0.31 log IU/mL, P = 0.67). No differences in decline of HCV RNA viral load were found in HCV genotype 3 patients. CONCLUSIONS: The IL-28B genotype impacts on viral kinetics during the first week of treatment with PEG-IFN/RBV in patients with HCV genotype 1/4.

BACKGROUND AND OBJECTIVE: Antiretroviral treatment of human immunodeficiency virus (HIV)-infected patients seems to increase the coronary risk (CR) in these patients. Adequate assessment of CR has significant implications for the management of these patients. Our objective was to compare 2 systems for assessing 10-year CR in HIV-infected patients. PATIENTS AND METHOD: CR was calculated in a prospective cohort of 205 HIV-infected patients using Framingham tables and REGICOR adapted tables. Prevalence of cardiovascular risk factors in these patients was evaluated. RESULTS: Mean age (standard deviation) was 41.4 (8.2) years. Most patients were taking antiretrovirals and had a good immunological status. Current smoking was reported by 77.1% of patients, while a history of dyslipidemia, hypertension, or diabetes was found in 29.3%, 7.3%, and 4.9% of patients, respectively. Lipodystrophy was seen in 41% of patients, abdominal obesity in 21.5%, and a sedentary lifestyle in 50.7% Mean values obtained were 6.55 (6.36) in the Framingham scale and 2.85 (2.31) in the REGICOR scale. A 10-year CR greater than 10% was found in 26 patients (12.9%) with the Framingham tables and in 4 patients (2.0%) with the REGICOR tables. The difference between both methods was significant (p < 0.001). CONCLUSIONS: Application of the Framingham tables to our cohort may overestimate the CR. Studies aimed at identifying the most adequate method for measuring CR in HIV-infected patients are required. Until such data are available, estimation of CR in these patients should be taken with caution.

Fundamento y objetivo: El tratamiento antirretroviral de los pacientes infectados por el virus de la inmunodeficiencia humana (VIH) parece aumentar su riesgo coronario (RC). La correcta valoración de éste tiene importantes implicaciones en el tratamiento de estos pacientes. Nuestro objetivo ha sido comparar 2 sistemas de evaluación del RC a 10 años en pacientes infectados por el VIH. Pacientes y método: Se calculó el RC en una cohorte prospectiva de 205 pacientes infectados por el VIH utilizando las tablas de Framingham y las tablas adaptadas REGICOR. Se evaluó la prevalencia de factores de riesgo cardiovascular de estos pacientes. Resultados: La edad media (desviación estándar) fue de 41,4 (8,2) años. La mayoría de los pacientes tomaba antirretrovirales y tenía buena situación inmunológica. Presentaba tabaquismo activo el 77,1%, antecedentes de dislipemia el 29,3%, de hipertensión el 7,3%, de diabetes el 4,9%, lipodistrofia el 41%, obesidad abdominal el 21,5% y sedentarismo el 50,7%. La valoración media en la escala Framingham fue de 6,55 (6,36) y en la escala REGICOR de 2,85 (2,31). El RC a 10 años fue mayor del 10% en 26 pacientes (12,9%) con las tablas de Framingham y en 4 (2,0%) con las tablas REGICOR. La diferencia entre ambos métodos resultó significativa (p < 0,001). Conclusiones: Aplicar las tablas Framingham en nuestra cohorte podría suponer una sobrestimación del RC. Son necesarios estudios que tengan como objetivo identificar el método más adecuado para medir el RC en pacientes infectados por el VIH. Mientras no dispongamos de estos datos, debemos tomar con precaución la estimación del RC en estos pacientes
