Immunodeficiency in preclinical smoldering adult T-cell leukemia.
We treated two Japanese patients with Pneumocystis carinii pneumonia. Inclusion bodies in both adrenal glands of patient no. 1 indicated a herpesvirus infection. The patient no. 2 recovered from the pneumonia upon sulfametoxazole-trimethoprim medication and high-dose methylprednisolone therapy. In both patients, anti-human T-cell leukemia virus type I (HTLV-I) antibodies were positive and anti-human immunodeficiency virus antibodies were negative. Peripheral leukocytes in patient no. 1 numbered 13.6 X 10(3)/microliter with 25% morphologically normal lymphocytes and 4% abnormal. Lymphocyte surface markers were 72.6%, CD4+, 13.6% CD8+ and 46.4% CD3+. In patient no. 2, leukocytes numbered 13.8 X 10(3)/microliter, including 18% lymphocytes, although no morphologically abnormal lymphocyte was evident. Lymphocyte markers were 36.6% CD4+, 16.8% CD8+ and 46.6% CD3+. Monoclonal integration HTLV-I proviral DNA in lymphocytes of patient no. 2 was demonstrated by Southern blotting. Thus, both patients must have had smoldering adult T-cell leukemia (ATL) without any cutaneous involvement, whereas the morphological diagnosis from peripheral blood smears was one of HTLV-I carrier status with a few atypical lymphocytes, i.e., the preclinical state of smoldering ATL. Pneumocystis carinii infections, a viral infection of the adrenals (no. 1), negative purified protein derivatives of the tuberculin reaction and suppressed blastogenesis of the peripheral lymphocytes indicated HTLV-I-induced impairment of the immune mechanism to have already occurred in both patients without there being a vast proliferation of ATL cells.

Measurement of tuberculostearic acid in sputa, pleural effusions, and bronchial washings. A clinical evaluation for diagnosis of pulmonary tuberculosis.
Gas chromatography/mass spectrometry combined with selected ion monitoring was used to measure tuberculostearic acid (TSA), in sputum, pleural effusion, and bronchial washing. The detection limit corresponded to the amount of TSA eluted from as low as 10(3) tubercle bacilli. Sputa were collected from 169 patients with active pulmonary tuberculosis, 35 clinically suspected to be active, 53 with obsolete pulmonary tuberculosis, and 160 with pulmonary diseases other than tuberculosis. TSA was positive in 90% of the patients with active pulmonary tuberculosis (152/169) and 71% of the clinically suspected cases (25/35), respectively. In contrast, less than 10% of the patients with obsolete tuberculosis or other pulmonary diseases had a positive TSA. Pleural effusions and bronchial washings were also collected from patients with active tuberculosis and from those with other diseases, as the controls. TSA in pleural effusions and bronchial washings was detected in 24 of 32 patients and 15 of 22 patients with active tuberculosis, respectively. In those with pulmonary diseases other than tuberculosis, only 8.7% of pleural effusion (4/46) and 4.3% of bronchial washing samples (3/69) showed a positive TSA. Therefore, the measurement of TSA is useful as a rapid and sensitive method for diagnosing pulmonary tuberculosis.
