title: [Clinical value of the blood lymphocyte count in thoracic sarcoidosis in adults. Apropos of 123 cases].
abstract: Lymphocyte counts in the peripheral blood were performed in 123 patients with thoracic sarcoidosis and in 33 healthy subjects. A significant decrease in the number of lymphocytes as compared to controls was observed, at least in patients of Caucasian origin. This lymphopenia was more pronounced when the disease was of more than 10 years' duration, was accompanied by extrathoracic manifestations and belonged to radiological groups II or III. The only parameter of pathological activity with which it correlated was serum angiotensin converting enzyme activity. Patients from the french Caribbean had scattered lymphocyte counts which precluded any firms conclusion.
