Relationship between radiological classification and the serological and haematological features of untreated pulmonary tuberculosis in Indonesia.

Immunological and metabolic responses were studied in 110 patients with newly diagnosed pulmonary tuberculosis and 32 healthy controls from similar socioeconomic backgrounds. The severity of lung involvement was assessed radiologically, but this was not related to the current features of cell mediated immunity or to those of many aspects of the serological response to Mycobacterium tuberculosis. However, the patients with more extensive pulmonary tuberculosis showed higher titres of IgG2 antibody to whole killed M. tuberculosis and to the ML34 epitope shared by many species of mycobacteria. The patients with more extensive pulmonary tuberculosis showed a more marked metabolic response to infection as manifested by changes in serum levels of acute phase reactant proteins. Accordingly, the metabolic responses are considered to be more likely to prove of value in clinical monitoring of patients for severity of infection, or of reactivation of infection with M. tuberculosis, than immunological responses.

Pulmonary necrobiotic nodules without rheumatoid arthritis.

Pulmonary necrobiotic nodules are the least common of the pulmonary lesions associated with rheumatoid arthritis. Histologically they are identical to subcutaneous rheumatoid nodules. Systemic rheumatoid arthritis usually precedes the development of pulmonary nodules. Seven cases where the pulmonary nodule appeared before or without the development of systemic rheumatoid arthritis are described. The typical histological and radiological features of necrobiotic nodules were found in each. In five of the seven the nodules were in more than one site and in five there were cavitating nodules. Spontaneous improvement occurred in one case. Pulmonary nodules preceded systemic rheumatoid arthritis in three cases and in the remaining four cases systemic rheumatoid arthritis has not yet appeared despite prolonged follow-up. In all patients, tests for rheumatoid factor have remained negative. The absence of circulating rheumatoid factor and systemic rheumatoid arthritis cannot exclude the diagnosis in these cases if the histological diagnosis is accepted as conclusive.

Relation between lung cancer, chronic bronchitis, and airways obstruction.

Since cigarette smoking is an important cause of lung cancer and chronic bronchitis both conditions should occur together more often in cigarette smokers than would result from chance. If they do commonly occur together then severe airways obstruction, which is often associated with chronic bronchitis, should also be often associated with lung cancer. To discover whether this were so three groups of patients were studied at the London Chest Hospital. Two hundred men and 43 women who presented with lung cancer provided information on the prevalence of defined chronic bronchitis and airways obstruction in those suffering from lung cancer. The third group consisted of 233 men presenting with defined chronic bronchitis who were kept under observation to discover how many would die from lung cancer. The results suggested that simple bronchitis and lung cancer often occur together but that obstructive bronchitis and lung cancer do not often occur together. The lack of association between lung cancer and severe airways obstruction requires an explanation.
