Objetivos

Examinar el papel de los linfocitos T vírgenes y de memoria (definidos por las isoformas CD45) en la infección tuberculosa reciente y en la enfermedad pulmonar y pleural. Correlacionar dichas subpoblaciones con las concentraciones séricas del receptor soluble de IL-2 (sIL-2R) e interleucina-6 (IL-6).

Métodos

Las subpoblaciones linfocitarias T (CD3, CD4, CD8), vírgenes (CD45RA), memoria (CD45RO) y células T activadas CD25+ (receptor de IL-2), fueron medidas en sangre y pleura en pacientes con infección tuberculosa reciente (n=7), tuberculosis pulmonar (n=22) y pleuritis tuberculosa (n=12). Se determinaron concentraciones sericas de sIL-2 e IL-6 en 13 pacientes con tuberculosis pleural o pulmonar y se correlacionaron con las subpoblaciones CD45RA y CD45RO.

Resultados

Se observó una linfocitosis T afectando a todas las subpoblaciones estudiadas, incluyendo células T vírgenes y de memoria, aunque sin modificación del cociente RA:RO, con respecto a controles. Se observó una marcada acumulación de células T de memoria y de células T CD25+ en la pleuritis tuberculosa. No hubo correlaciones entre concentraciones de sIL-2 e IL-6 y subpoblaciones T vírgenes o memoria.

Conclusiones

En la infección tuberculosa reciente se evidenció una linfocitosis T, afectando a células vírgenes y de memoria, aunque sin predominio de una sobre otra. En la pleuritis tuberculosa hay una compartimentalización de células T de memoria y celulas T activadas que presumiblemente representen un papel fundamental en la inmunidad local frente a M. tuberculosis.

Objective

To examine the role of naive and memory T cells (as determined by CD45 isoforms) in recent tuberculosis infection and in pulmonary and pleural forms to the disease. To relate such subpopulations to serum levels of soluble IL-2 receptor (sIL-2R) and interleukin-6 (IL-6).

Methods

T cell subpopulations (CD3, CD4, CD8), naive (CD45RA), memory (CD45RO) and activated CD24+ T cells (IL-2 receptor) were measured in the peripheral blood and pleura of patients with recent tuberculosis infection (n=7), pulmonary tuberculosis (n=22) and tuberculosis pleurisy (n=12). Serum levels of sIL-2 and IL-6 were determined in 13 patients with pleural or pulmonary tuberculosis and their relation to CD45RA and CD45RO subsets was analyzed.

Results

T lymphocytosis involving all the subpopulations studied, including naive and memory T cells, was detected, although the RA:RO ratio did not change in relation to control levels. Marked increases in memory T cells and CD24+ T cells were found for patients with tuberculous pleurisy. sIL-2 and IL-6 levels were unrelated to naive and memory T cell subpopulations.

Conclusions

T lymphocytosis involving all T cell subsets can be observed in recent tuberculosis infection; both naive and memory T cells are implicated, although neither one predominates over the other. In tuberculous pleurisy there is compartmentalization of memory and activated T cells, which presumably play important roles in the local immune response to Mycobacterium tuberculosis.
