RESUMEN

Objective: To determine the frequency of misdiagnosis of tuberculosis in interstitial lung disease cases


Methods: This is a prospective study including patients registered in the interstitial lung disease clinic, Jinnah Postgraduate Medical Center, Karachi, during May-June 2017. Diagnosis of tuberculosis was only confirmed if there was any bacteriological evidence of tuberculosis at the time of diagnosis or if there was improvement in symptoms after treatment in patients diagnosed as having tuberculosis on clinical grounds


Results: Seventy-three patients were included in the study, out of which 53 [72.60%] were females and 20 [27.39%] were males. Tuberculosis was treated before presentation in 28 [38.35%] of interstitial lung disease patients. Except for two silicosis patients who had smear positive tuberculosis, rest of the patients were misdiagnosed as having tuberculosis


Conclusion: Interstitial lung diseases are the disorders that are frequently unrecognized and misdiagnosed. More commonly the confusion is with tuberculosis. Thorough knowledge about interstitial lung diseases should be provided to the primary care physicians, especially in countries with high tuberculosis burden, so that to limit maltreatment with anti-tuberculous drugs when they are not needed and early referral to interstitial lung disease clinic

RESUMEN

Objective: To evaluate the effectiveness and safety of using BiPAP through endotracheal tube in comatose Chronic Obstructive Pulmonary Disease [COPD] patients with hypercapnic respiratory failure


Methods: This is a prospective study done at Department of Chest Medicine, Jinnah Postgraduate Medical Centre, Karachi, during March to June 2017. It included all comatose COPD patients with hypercapnic respiratory failure who had a poor functional status prior to the illness and who did not meet the criteria to be kept on mechanical ventilator. Patients with apnea and other causes of coma were excluded. These patients were applied BiPAP through endotracheal tube and its response on blood gases and neurological status was evaluated


Results: The success rate of BiPAP through endotracheal tube was 70.5% [31/44]. Improvement in Glasgow Coma Scale [GCS] score [p<0.01], pH [p<0.01], and PaCO2 [<0.01] was observed among the responders following two hours and 24 hours of therapy. No significant difference was found in response with regards to gender, smoking status, prior use of noninvasive ventilation or duration of disease. No complications were observed during the therapy


Conclusion: In resource poor settings, the use of BiPAP through endotracheal tube can be an effective and safe intervention for comatose COPD patients with hypercapnic respiratory failure
