Abstract

Introduction: in individuals with chronic kidney disease, sarcopenia is prevalent and is associated with increased morbidity and mortality, and the occurrence of cardiovascular complications. Objective: to verify the relationship between sarcopenia and inflammation in hemodialysis patients. Methods: a cross-sectional study with 209 patients in five hemodialysis units. Demographic, socioeconomic, body composition, clinical laboratory, and functional data were collected. Sarcopenia was diagnosed according to the European Working Group on Sarcopenia in Older People (grip strength < 27 kg for men and < 16 kg for women; DEXA muscle mass < 7.0 kg/m² for men and < 5.5 kg/m² for women). Inflammation was assessed by C-reactive protein. Results: mean age was 51.9 ± 15.0 years, with a predominance of males (59.3 %). The prevalence of sarcopenia was 29.1 % and that of inflammation was 50.2 %. A Poisson regression analysis showed that sarcopenia was associated with increased hsCRP values (PR: 1.06; 95 % CI: 1.01-1.10; p-value = 0.005); BMI (PR: 0.74; 95 % CI: 0.65-0.84; p-value < 0.001); age (PR: 1.02; 95 % CI: 1.00-1.03; p < 0.001); male (PR: 5.75; 95 % CI: 3.20-10.34; p-value < 0.001); presence of diabetes mellitus (DM) (PR: 1.87; 95 % CI: 1.27-2.74; p-value < 0.001); % body fat (PR: 1.07; 95 % CI: 1.04-1.09; p-value < 0.001). Conclusion: the prevalence of sarcopenia can be considered high in this study, as well as inflammation. Being inflamed, presence of DM, being male, increasing age, and % body fat were risk factors for sarcopenia. On the other hand, increased BMI had a protective role.

Introducción: en individuos con enfermedad renal crónica, la sarcopenia es prevalente y está asociada a un aumento de la morbilidad y la mortalidad, y a la aparición de complicaciones cardiovasculares. Objetivo: verificar la relación entre sarcopenia e inflamación en pacientes en hemodiálisis. Métodos: estudio transversal de 209 pacientes en cinco unidades de hemodiálisis. Se recopilaron datos demográficos, socioeconómicos, de composición corporal, laboratorio clínico y funcional. La sarcopenia se diagnosticó conforme al Grupo de Trabajo Europeo sobre Sarcopenia en Personas Mayores (fuerza de agarre < 27 kg para hombres y < 16 kg para mujeres; masa muscular DEXA < 7.0 kg/m² para hombres y < 5.5 kg/m² para mujeres). La inflamación se evaluó mediante la proteína C-reactiva. Resultados: la edad media fue de 51,9 ± 15,0 años, con predominio de varones (59,3 %). La prevalencia de la sarcopenia fue del 29,1 % y la de la inflamación del 50,2 %. El análisis de regresión de Poisson mostró que la sarcopenia se asociaba con un aumento de los valores de hsCRP (PR: 1,06; IC del 95 %: 1,01-1,10; valor de p = 0,005); IMC (PR: 0,74; IC del 95 %: 0,65-0,84; valor p < 0,001); edad (PR: 1,02; IC 95 %: 1,00-1,03; p < 0,001); hombre (PR: 5,75; IC 95 %: 3,20-10,34; valor p < 0,001); presencia de DM (PR: 1,87; IC 95 %: 1,27-2,74; valor p < 0,001); % de grasa corporal (PR: 1,07; IC 95 %: 1,04-1,09; valor p < 0,001). Conclusión: la prevalencia de la sarcopenia puede considerarse alta en este estudio, así como la inflamación. Tener inflamación, la presencia de DM, ser hombre, la mayor edad y el % de grasa corporal resultaron ser factores de riesgo de sarcopenia. Por otro lado, el aumento del IMC tuvo un papel protector.
