KIR-HLA clase i y tuberculosis pulmonar en población amerindia del Chaco, Argentina

Abstract

Resumen Introduccion La susceptibilidad a la tuberculosis pulmonar (TB) es multifactorial, por lo que factores geneticos como las moleculas del complejo mayor de histocompatibilidad (CMH) y los receptores tipo inmunoglobulinas presentes en celulas NK (KIR) podrian predisponer al desarrollo de la misma. Objetivo Evaluar si algun alelo de HLA clase i en combinacion con determinados KIR podria estar relacionado con el desarrollo de TB en la comunidad amerindia Wichi en el noreste argentino. Metodos En un estudio de cohorte se incluyeron 18 familias, 35 individuos afectados con TB, 84 convivientes familiares y 63 controles sanos del mismo grupo etnico. Los loci A y B de HLA clase i se tipificaron mediante amplificacion generica seguida de hibridacion reversa (Dynal), el locus C por PCR-SSOP. Los receptores KIR fueron amplificados con primers de secuencia especifica SSP-PCR. Resultados Se observo una asociacion altamente significativa con el alelo B*35:19/47 en TB vs. contactos familiares [Pc = 0,0051] y vs. controles [Pc = 0,0033] y con el alelo HLA-C*03 en TB vs. contactos [Pc = 0,014] y vs. controles [Pc = 0,0033]. Cuando se analizaron los receptores KIR, se observo aumento de la frecuencia KIR2DL3/KIR2DL3 en combinacion con el grupo C1 de HLA-C (p = 0,018). C*03 pertenece al grupo C1, por lo que podemos pensar que esta combinacion ejerza una fuerte accion inhibitoria sobre la celula infectada con Mycobacterium . Conclusion HLA-B35:19/47-HLA-C*3 podrian ser un factor de susceptibilidad a TB y la combinacion KIR2DL3-HLA-C1, por su efecto inhibitorio sobre las celulas NK, podria contribuir al curso clinico de la infeccion por M. tuberculosis.
