Abstract

Objectives This study aimed to examine the change and significance of immune parameters in patients with sputum smear-positive pulmonary tuberculosis (TB) after 2 months of intensive phase anti-TB treatment. Methods The immune parameters of 232 cases of sputum smear-positive pulmonary TB were detected before and after 2 months of intensive phase anti-TB treatment and compared with 50 cases from healthy volunteers (controls). The T lymphocyte cell population in peripheral blood was detected using flow cytometry. Serum levels of interleukin (IL)-1β, soluble interleukin-2 receptor, IL-6, and tumour necrosis factor-α were measured by ELISA. Results After 2 months of intensive phase anti-TB treatment, a reduction in the percentage of CD4+ T cells showed a significant restoration similar to that of controls. Moreover, after intensive anti-TB treatment, serum levels of IL-1β, soluble interleukin-2 receptor, IL-6, and tumour necrosis factor-α were significantly decreased compared with before treatment. Additionally, serum levels of IL-1β and IL-6 showed a diminished recovery compared with controls. Conclusions Our findings suggest immunological recovery in patients with pulmonary TB after intensive phase treatment. Therefore, serum cyt...Continue Reading
