Epidemiological, clinical, and laboratory factors associated with chronic kidney disease in Mexican HIV-infected patients / Fatores epidemiológicos, clínicos e laboratoriais associados à doença renal crônica em pacientes mexicanos infectados pelo HIV

ABSTRACT

ABSTRACT Aim: To determine the prevalence of chronic kidney disease (CKD) and the epidemiological, clinical, and laboratory factors associated with CKD in Mexican HIV-infected patients. Methods: Cross-sectional study. We included 274 patients with HIV/AIDS. CKD was defined by the estimated glomerular filtration rate (eGFR < 60 mL/min/1.73 m2 assessed by CKD-EPI) and albuminuria criteria from KDIGO guidelines. Clinical, epidemiological, and laboratory characteristics were compared between patients with and without CKD. The factors associated with CKD were assessed by logistic regression analysis. Results: The mean age was 41±11 years, and 72.3% of the patients were men. The global prevalence of CKD was 11.7% (n = 32); 7.2% (n = 20) were defined by eGFR criterion; 7.6% (n = 21), by the albuminuria criterion; and 3.2% (n = 9), by both CKD criteria. The most frequently observed stages of CKD were KDIGO G3A1 stage with 4.7% (n = 13), KDIGO G1A2 stage with 3.6% (n = 10) and KDIGO G3A2 stage with 1.7% (n = 5). The factors associated with CKD were use of abacavir/lamivudine (OR 3.2; 95% CI 1.1-8.9; p = 0.03), a CD4 lymphocyte count < 400 cells/µL (OR 2.6; 95% 1.03-6.4, p = 0.04), age (OR 1.1; 95% CI 1.04-1.2, p = 0.001) and albuminuria (OR 19.98; 95% CI 5.5-72.2; p < 0.001). Conclusions: CKD was a frequent complication in HIV-infected patients. These findings confirm the importance of screening and the early detection of CKD, as well as the importance of identifying and treating traditional and non-traditional risk factors associated with CKD.

RESUMO

RESUMO Objetivo: Determinar a prevalência de doença renal crônica (DRC) e os fatores epidemiológicos, clínicos e laboratoriais associados à DRC em pacientes mexicanos infectados pelo HIV. Métodos: Estudo transversal. Incluímos 274 pacientes com HIV/AIDS. A DRC foi definida pela taxa de filtração glomerular estimada (TFGe < 60 mL/min/1,73 m2, avaliada pelo CKD-EPI) e pelos critérios de albuminúria das diretrizes do KDIGO. As características clínicas, epidemiológicas e laboratoriais foram comparadas entre pacientes com e sem DRC. Os fatores associados à DRC foram avaliados por análise de regressão logística. Resultados: A média da idade foi de 41 ± 11 anos e 72,3% dos pacientes eram homens. A prevalência global de DRC foi de 11,7% (n = 32); 7,2% (n = 20) foram definidos pelo critério TFGe; 7,6% (n = 21), pelo critério da albuminúria; e 3,2% (n = 9), pelos dois critérios para DRC. Os estágios mais frequentemente observados da DRC foram o estágio KDIGO G3A1 com 4,7% (n = 13); estágio KDIGO G1A2 com 3,6% (n = 10) e estágio KDIGO G3A2 com 1,7% (n = 5). Os fatores associados à DRC foram o uso de abacavir/lamivudina (OR 3,2; IC95% 1,1-8,9; p = 0,03), contagem de linfócitos CD4 < 400 células/µL (OR 2,6; 95% 1,03-6,4, p = 0,04), idade (OR 1,1; IC95% 1,04-1,2, p = 0,001) e albuminúria (OR 19,98; IC95% 5,5-72,2; p < 0,001). Conclusões: A DRC foi uma complicação frequente em pacientes infectados pelo HIV. Esses achados confirmam a importância do rastreamento e da detecção precoce da DRC, bem como a importância de identificar e tratar os fatores de risco tradicionais e não tradicionais associados à DRC.
