title: A study of serum malondialdehyde and cytokine in tuberculosis patients.
abstract: BACKGROUND
  Tuberculosis (TB) is a common and a deadly infectious disease which is caused by Mycobacterium tuberculi. Inflammatory cytokines play an important role during the course of the disease and they may be responsible for tissue damage which is caused by lipid peroxidation.
  
  
  METHODS
  The present study was conducted in the Department of Biochemistry and patients were selected from Department of TB and Chest Sri Aurobindo Institute of Medical Sciences and also from Manorama Raje Tuberculosis Hospital, Indore. 32 healthy controls and 35 pulmonary TB patients were compared initially for their serum Malondialdehyde (MDA) and tumour necrosis factor alpha (TNF α) levels. Serum TNF α and MDA levels were correlated.
  
  
  RESULTS
  TNF α and MDA levels in serum were significantly increased (p<0.001) in pulmonary tuberculosis patients as compared to those of controls. Increased Serum TNF α was positively correlated to MDA levels and it was found to be statistically not significant (correlation coefficient r =0.282,p> 0.05 ).
  
  
  CONCLUSIONS
  The present study supports the view that there may be a link between lipid peroxidation and cytokine response and relative roles of cytokines and lipid peroxidation in the pathogenesis of tuberculosis.
