Objectives: Cryptogenic Organizing Pneumonia (COP) is a relatively rare disorder which is gratifying to treat due to its prompt steroid responsiveness. There have been only 2 case reports on COP from India but no large series entity reported from this country.
Methods: The medical records of all patients with biopsy (histopathology) proven COP admitted in a tertiary care hospital in Mumbai (2000-2005) were retrospectively analyzed. We looked at clinical and radiographic profiles, initial diagnosis and treatment, lag period to starting definitive therapy and steroid responsiveness.
Results: When compared to other series of patients with COP, our series showed several similarities and some differences. Distinctive features were the striking female preponderance and the utility of transbronchial biopsies in establishing the diagnosis. Long delays in diagnosis with patients mislabeled as tuberculosis or pneumonia, lead to delays in starting steroids resulting in 21% of our patients continuing to deteriorate.
Conclusions: This comprehensive review of COP, the first of its kind from India, reveals its varied clinical and radiographic spectrum. A high index of suspicion will lead to prompt steroid therapy which will result in better patient outcome.
