Respiratory infections of 19 subjects of advanced age and/or with underlying respiratory disease were treated with cefoperazone (CPZ) and its clinical effects were studied. Sixteen subjects suffered from respiratory tract infection and 3 subjects had pneumonia. The age of the subjects ranged from 39 to 77 years with the mean of 63.8, 7 of them being more than 70 years of age. The underlying respiratory diseases included chronic pulmonary emphysema in 6 subjects, diffuse panbronchiolitis in 3, bronchiectasis in 3, silicosis in 2 and one each of chronic bronchitis, pulmonary fibrosis, lung cancer and old pulmonary tuberculosis. One case, 75 years of age, had renal insufficiency. The daily dose of CPZ was 4 grams in 18 of the 19 subjects and the duration of administration ranged 5 to 22 days. The remaining 1 subject received 2 g of CPZ daily for 6 days. Clinical effects were judged from the changes in fever, cough, amount of sputum, dyspnea, rales, cyanosis, chest X-ray, white blood cell counts, CRP, erythrocyte sedimentation rates and results of sputum culture. Clinical effects were good in 16 subjects, fair in 1, and poor in 2. Bacteriological follow-up was carried out in 13 subjects. Infecting bacteria were eliminated from 5 subjects, reduced in 2 and, in 4 subjects, they were replaced by other bacteria. In 1 subject, P. aeruginosa was isolated from sputum even after the treatment with CPZ, and in another subject H. influenzae relapsed immediately after the cessation of the CPZ treatment.(ABSTRACT TRUNCATED AT 250 WORDS)

The relationship between silicosis and tuberculosis is well known. Also other mycobacteria such as Mycobacterium kansasii often occur in association with pneumoconiosis. However, there are few reports describing an association of M. avium-intracellulare complex (MAC) lung disease and pneumoconiosis. The purpose of the present study is to describe clinical features of MAC respiratory infection associated with pneumoconiosis. Eleven patients with MAC respiratory infection associated with pneumoconiosis (all men, 6 with silicosis and 5 with welders' pneumoconiosis) were collected. A determination of whether or not MAC caused pulmonary disease was made using the 1997 criteria required by the American Thoracic Society. Radiologically, cavity formation as well as upper lung field predominance of MAC disease were observed in 8 of 11 cases (72.7%). Two of 11 patients died of respiratory failure. Our present study clearly demonstrates that clinical features of MAC respiratory infection associated with pneumoconiosis were different from MAC without underlying diseases.

Respiratory tract infections are the most common diseases that are associated with social burden for the patient. Western Rajasthan has cases of Cystic fibrosis due to migrant population. The dry and dusty environment has led to prevalence of silicosis and COPD. As per IDSA (2018) guidelines, patients attending Out-Patient Department do not need microbiological investigations for lower respiratory tract infections (LRTI) except for influenza and tuberculosis.
