Steroids are useful in treating Tuberculosis patient with-

Glucocoicoids reduce inflammation and limit tissue damage; they are currently recommended when treating pericardial ,lymphadenitis patients having TB or meningeal disease, and in children with endobronchial disease. They may confer benefit in TB of the ureter, pleural effusions and extensive pulmonary disease, and can suppress hypersensitivity drug reactions. Surgery should be considered in cases complicated by massive haemoptysis, loculated empyema, constrictive pericarditis, lymph node suppuration, and spinal disease with cord compression, but usually only after a full course of antituberculosis treatment.
