Abstract:
Idiopathic pulmonary fibrosis (IPF) is defined as a specific form of chronic fibrosing interstitial pneumonia limited to the lung and associated with the histologic appearance of usual interstitial pneumonia (UIP) on lung biopsy. It is characterized by progresive dyspnea, worsening of pulmonary function and radiographically, by patchy subpleural interstitial infiltrates with minimal ground glass appearance predominantly affecting the lung bases. The etiology is unknown and no therapy has been clearly shown to prolong survival. The diagnosis, which earlier was difficult to establish, is now based on guidelines of American Thoracic Society. Newer insight into its etiopathogenesis, particularly the mechanisms involved including T helper 1 (Th1) and T helper 2 (Th2) types of responses occurring after the initial and repetitive lung insults and the ineffectiveness of conventional modes of therapy has prompted clinicians worldwide to look for alternative modes of therapy. Conventional therapy for this disorder has been steroids and immunosuppressives. Immunomodulators (Interferon gamma 1b) and antioxidants (Glutathione and its precursor N-acetyl cysteine) are promising results in this, otherwise, uniformly fatal condition.
