Pulmonary tuberculosis activates lipid peroxidation (LPO) and apoptosis in blood cells. While LPO normalizes post-treatment, apoptosis remains elevated, indicating persistent cellular stress in tuberculosis patients.
Area of Science:
- Biochemistry
- Immunology
- Cell Biology
Background:
- Pulmonary tuberculosis (TB) is an infectious disease affecting the lungs.
- Cellular damage and immune responses are critical in TB pathogenesis.
- Lipid peroxidation (LPO) and apoptosis are key indicators of cellular stress and death.
Purpose of the Study:
- To investigate the role of LPO and apoptosis in mononuclear cells of pulmonary TB patients.
- To assess the impact of standard chemotherapy on LPO and apoptosis during TB treatment.
Main Methods:
- Studied LPO and apoptosis in blood mononuclear cells (lymphocytes and monocytes).
- Analyzed these markers in patients before and during anti-TB chemotherapy.
- Compared marker levels pre-treatment, during treatment, and post-treatment.
Main Results:
- Pulmonary TB was associated with increased LPO and apoptosis in lymphocytes and monocytes.
- These cellular changes were evident both before and after intensive care.
- Post-therapy, LPO levels returned to normal, but apoptosis activity remained significantly high.
Conclusions:
- Standard chemotherapy effectively reduces LPO in TB patients.
- Persistent high apoptosis activity post-treatment suggests ongoing cellular damage or immune dysregulation.
- Further research is needed to understand the implications of sustained apoptosis in TB recovery.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
