Humoral response to mycobacterial heat shock proteins in patients with constrictive pericarditis caused by tuberculosis and its implications for pathogenesis.

Tuberculous pericarditis is one of the commonest causes of cardiac failure in Transkei and the surrounding regions in southeast Africa. About 20% of patients with clinically diagnosed tuberculous pericardial effusion go on to develop pericardial fibrosis (i.e., construction), a complication which is associated with significant mortality and morbidity. The pathological mechanisms underlying this aberrant inflammatory response are poorly understood, and there is a lack of reliable pointers (clinical or laboratory) in predicting the likelihood of development of constriction. We studied the humoral response to mycobacterial heat shock proteins (65 and 71 kDa) in 25 patients with culture-positive tuberculous pericardial effusion and found a significant correlation between high anti-mycobacterial hsp60 antibody titers (before treatment) and subsequent development of fibrosis (P = 0.035 by logistic regression), which is independent of the effect of the use of prednisolone as adjuvant therapy. Possible mechanisms underlying the pathogenesis of pericardial constriction in tuberculosis are postulated.

A patient with insidious onset of exertional dyspnoea.

The case history is presented of a 42 year old woman with pulmonary artery occlusion due to tuberculous vasculitis that masqueraded as chronic pulmonary artery embolism and led to severe life threatening haemoptysis necessitating emergency pneumonectomy. It is concluded that obliterative tuberculous endarteritis of the pulmonary arteries should be considered in the differential diagnosis of any acquired obstruction of pulmonary arteries.

Tuberculous pericarditis in Birmingham.

Forty-one patients with acute tuberculous pericarditis were studied retrospectively. Anti-tuberculosis chemotherapy alone was effective in thirty. Five patients died, two from unrelated causes, two due to delayed diagnosis, and one after pericardiectomy. Constrictive pericarditis developed in seven patients, six of whom had successful pericardiectomy. Corticosteroids could not be shown to have reduced the risk of developing constriction. When constriction occurred it did so within the first six months of illness in all cases in contrast to a separate series of 15 patients who presented with constrictive pericarditis. These had had no previous history of tuberculosis, and in 10 cases where pericardiectomy was done, no histological evidence of tuberculosis was found. They were European with an average age of 49 years whereas in the group with acute tuberculous pericarditis 33 were Asian and the average age was 36 years.

Pericardial tuberculoma. An unusual cause of mediastinal mass.

Pericardial tuberculoma can appear as a solitary mediastinal mass along the left-heart border. The authors discuss two cases and cite three additional cases to demonstrate that, although rare, pericardial tuberculoma merits consideration in the differential diagnosis of mediastinal masses, particularly in patients with histories of tuberculosis.
