Abstract
Objetivo. - determinar la incidencia y riesgo de TB latente y tuberculosis activa en pacientes con enfermedades reumáticas autoinmunes que reciben terapia biológica, así como establecer los factores de riesgo asociados en esta población.
Diseño. - Se realizó un estudio transversal, retrospectivo en pacientes con enfermedades reumáticas en tratamiento con medicación biológica del Hospital de Especialidades Dr. Teodoro Maldonado Carbo de Guayaquil-Ecuador que acudieron a la consulta de reumatología entre enero de 2010 y enero de 2024.
Resultados.- Entre los factores que mostraron asociación significativa para TB activa previo a terapia biológico se encuentra: infección por VIH/SIDA (p<0.001), enfermedad pulmonar intersticial (p=0.016), uso de leflunomida (p=0.009) y LES (p=0.006). Posterior al inicio de terapia biológica, 217 (13.8%) y 29 (1.8%) pacientes fueron catalogados con TB latente y TB activa respectivamente. Se observó correlación bilateral significativa para reactivación de TB en sujetos con sexo masculino [OR 3.3 (IC95% 1.6 – 7) p=<0.001], AR [OR 4.3 (IC95% 1.3 – 13.7) p=0.018], EA [OR 2.4 (IC95% 1 – 5.5) p=0.037], tratamiento con Adalimumab [OR 3.1 (IC95% 1.3 – 7.1) p=0.004] y ciclofosfamida [OR 3.7 (IC95% 1.1 – 13.) p=0.025].
La tasa de incidencia de tuberculosis por 10.000 personas/año posterior a inicio del tratamiento biológico fue de 184.8 casos para TB activa y 1383 para TB latente. El riesgo de reactivación TB en la cohorte total tuvo un OR 2.9 (CI95% 1.4 – 6.2) p=0.004. No se observaron diferencias significativas para sexo, edad, tipo de enfermedad reumática autoinmune, tipo de biológico, comorbilidades o FARMES.
