Background - Tuberculous pleurisy can result in pleural fibrosis, calc
ification and thickening. To prevent these complications, corticostero
ids are frequently used in addition to antituberculous drugs; however,
new therapeutic regimens can control the disease and minimise the seq
uelae, and there is no convincing evidence of the benefit of the use o
f corticosteroids as adjuvant therapy. Methods - Patients received iso
niazid 5 mg/kg and rifampicin 10 mg/kg daily for six months. Additiona
lly, they were randomly assigned to a double blind treatment with eith
er prednisone (1 mg/kg/day for 15 days and then tapering off) or place
bo during the first month of treatment. Different clinical, radiologic
al, and functional parameters were evaluated to assess the effect of c
orticosteroids. Results - Fifty seven patients received prednisone and
60 placebo. At the end of the treatment the clinical outcome, the rat
e of reabsorption of the pleural fluid, the pleural sequelae, as well
as lung capacity were similar in both groups. Conclusions - Corticoste
roids do not influence the clinical outcome or the development of long
term pleural sequelae in tuberculous pleurisy.
