The experience with nontuberculous mycobacterial disease at an "acute-care" hospital in southern California between 1971 and 1981 is reported. Forty-five patients with nontuberculous mycobacterial or Mycobacterium bovis-caused disease were identified by retrospective review. Of these, 31 patients (69%) had pulmonary infection alone, nine (20%) had cervical lymphadenitis, two (4%) had disseminated disease, two (4%) had cutaneous infection, and one had soft tissue infection. Nonmycobacterial pulmonary disease was noted in 15 (33%) of the patients and underlying malignant neoplasms were noted in eight (18%). Symptoms most frequently reported at initial examinations of patients with pulmonary disease were cough, weight loss, sputum production, and fatigue. Response to therapy was more successful in patients with Mycobacterium kansasii-caused disease than in those with Mycobacterium avium-intracellulare-caused pulmonary disease. We conclude that nontuberculous mycobacterial disease is not rare in the general hospital setting in southern California.

Corynebacterium equi, an aerobic, variably acid-fast, gram-positive "diphtheroid," is an unusual cause of pulmonary infection in immunosuppressed patients. Initially, infection with C. equi may be mistaken for a mycobacterial infection. Two cases in a two-year period were observed and compared with the 10 cases previously reported in the literature. All but one patient had pulmonary involvement, and the presentation of all other patients was typically insidious, with fatigue, fever, and nonproductive cough. Chest roentgenograms showed cavitary lesions in seven of 11 patients. Four of 12 patients had associated bacteremias, and three of 12 had subcutaneous abscesses or lymphadenitis. One of our patients developed multiple brain abscesses. Overall mortality was 25%. The organism is susceptible to vancomycin, erythromycin, aminoglycosides, and chloramphenicol. Optimal duration of antibiotic therapy and the proper role of surgery in treatment is uncertain, but relapses have been common and many weeks of antibiotic therapy have generally been required for cure.

Two cases of disseminated infection caused by Mycobacterium intracellulare were reported and discussed. In the first case, the patient was a fifty-seven-year-old male who complained of general fatigue, weight loss, and fever. Biopsy of the right inguinal lymph nodes and the liver revealed infiltration by histiocytes engulfing many acid-fast bacilli. At autopsy and egg-sized abscess was found is the region of the right iliac lymph nodes. Histological examination showed histiocytic infiltration in the abscess wall, neighboring lymph nodes, liver, and spleen. In the second case, the patient was a four-year-old boy, who had persistent fever and splenomegaly. Splenectomy was performed and histological examination of the spleen revealed multiple nodular infiltration by swollen histiocytes with many acid-fast bacilli in their cytoplasm. The bone marrow aspirates and liver tissue obtained in the necropsy also showed many histiocytes containing many acid-fast bacilli. The authors emphasized the importance of paying special attention to atypical mycobacteriosis in feverish patients having lesions with a proliferation of histiocytes.

A rare case of hepatic granulomatosis due to Mycobacterium scrofulaceum is presented. The prolonged clinical course before liver biopsy was characterized by a disproportionate rise in alkaline phosphatase, moderate hepatomegaly, tiredness, and low-grade fever. Liver biopsy confirmed primary liver granulomatosis in the absence of evidence of pulmonary or systemic involvement. The patient was treated with INH, rifampin, and cycloserine with amelioration of clinical symptoms and return of serum alkaline phosphatase levels to normal.

The first case of disseminated Mycobacterium bovis infection with meningitis in an AIDS patient is reported. A 54-year-old male HIV-positive patient was admitted for evaluation of fever, weight loss, inappetence, fatigue and malaise. Mycobacterium bovis (non-BCG) was isolated from blood, bone marrow, stool, urine, sputum, abdominal lymph nodes and cerebrospinal fluid. Antituberculous therapy using a five-drug regimen plus steroids resulted in complete recovery.

A 67-year-old woman had developed weakness, fatigue and a 10 kg weight loss over the past year. On examination a cylindrical mass was palpated in the right middle abdominal cavity. Erythrocyte sedimentation rate was increased to 87/126 mm, there was an hypochromic anaemia (haemoglobin 9.1 mg/dl) and an hypoalbuminaemia (32 g/l) with an increase in alpha 2-globulins (9.4 g/l), Cholinesterase activity was decreased to 588 U/l. X-ray film of the abdomen revealed a calcified mesenteric lymph-node and coloscopy demonstrated polypoid tumorous changes with ulcerations, extending from the pole of the caecum to the right flexure. Histological examination showed epithelioid-cell granulomas with Langhans giant cells. Culture grew Mycobacterium tuberculosis, confirming the diagnosis of intestinal tuberculosis. She was treated with oral doses of isoniazid (300 mg daily), rifampicin (600 mg daily) and pyrazinamide (2 g daily) for 2 months, followed by isoniazid and rifampicin for a further 4 months. After this the laboratory tests were within normal limits and urine as well as stool samples contained no acid-fast bacilli. As the patient felt so well she declined another coloscopy.

The chest radiograph of a 35-year-old man with fatigue, exertional dyspnoea and haemoptyses revealed a cavity in the left upper lobe and a shrunken left lung with radiolucency greater than that on the right. Acid-fast rods in sputum were identified as Mycobacterium kansasii on culture. Scintigraphy showed a 9% residual perfusion on the left and abnormal ventilation, compatible with Swyer-James syndrome. This had favoured the development of a mycobacterial infection. There was also a decrease in ciliary function (rate of 4-7 Hz, normal: 10-11). Treatment, begun when tuberculosis had been suspected, was after sensitivity tests changed to a combination of rifampicin (600 mg), ethambutol (1600 mg) and protionamide (500 mg) daily. There was marked regression of the findings within 4 weeks, but treatment was prematurely stopped after 11 months. Two years later there was a recurrence which again responded well to the same drug regimen with additional sulphamethoxazole (1600 mg/d).

In order to determine the prevalence of cortisol deficiency in advanced HIV disease and to examine whether it may be predicted by clinical features or biochemical abnormalities, we conducted a prospective study which assessed responses to a rapid ACTH stimulation test (short-duration synthetic corticotrophin test, synacthen test) in HIV-positive patients with a CD4 count of < or = 50 x 10(6)/l. Subjective fatigue, postural drop in blood pressure, electrolyte changes, presence of concurrent opportunist infection and drug treatment were recorded. Cortisol responses were defined as 'normal' (a post stimulation cortisol level > or = 450 nmol/l), 'abnormal' (post stimulation cortisol level < 350 nmol/l) or 'impaired' (an intermediate response). Of 49 patients tested (42 male, seven female), a suboptimal response (abnormal or impaired) was found in 14 (29%) and frank insufficiency in eight (16%). Cortisol deficiency was not predicted by postural drop in blood pressure, biochemistry or symptoms of fatigue. Patients with an impaired/abnormal test were not more likely to have cytomegalovirus or mycobacterial disease but were more likely to be taking megestrol acetate (P = 0.05, Fisher's exact test). Two of three patients with initially normal tests developed impaired/abnormal cortisol responses on re-testing 6-9 months later. Cortisol deficiency is common in late stage HIV disease, but symptoms of fatigue and postural hypotension, as well as biochemical findings, are poor predictors of cortisol deficiency. We found good subjective response to therapy. Routine screening by a rapid ACTH stimulation test is recommended in HIV-positive patients with CD4 count < or = 50 x 10(6)/l. Re-testing at regular intervals may be necessary. The interaction between megestrol acetate, cortisol metabolism and synacthen testing requires further investigation.

A vaccine consisting of four allogeneic colon carcinoma cell lines (DLD-1, HCT116, WiDr, and T84) mixed with the adjuvant DETOX (Mycobacterium phlei cell wall and Salmonella minnesota lipid A) was administered to 25 patients with low-volume metastatic colorectal carcinoma. The first eight patients received vaccine only, given intradermally on three occasions at 3-week intervals. Subsequent patients also received subcutaneous interleukin-1 alpha (IL-1 alpha), 0.3-0.5 microgram/m2 per day for 8 days after each vaccination in an outpatient setting. Vaccine alone caused local erythema, induration, and pruritus. IL-1 caused fevers, chills, and rigors that started in 4 h and lasted 1-2 h. One patient developed a brief loss of consciousness with a rigor that resolved without sequelae. One episode of mild hypotension occurred. Fatigue occurred by day 8 of IL-1. A substantial increase in the number of patients with positive skin tests to DLD-1 and HCT116 occurred after vaccine treatment both without and with IL-1 alpha. An allogeneic cell vaccine plus subcutaneous IL-1 was administered safely to outpatients with some evidence of in vivo effect observed.

A 49-year-old male was admitted to our hospital complaining of cough and general fatigue. There was nothing unusual about his past history, and he has been healthy. On admission, a chest roentogenogram revealed an infiltrative shadow with a cavity in the left middle and lower fields. Because the acid fast staining of a bronchoscopic specimen was positive for mycobacteria, he was transferred to another hospital to be treated as pulmonary tuberculosis. Culture tests of multiple specimens were positive, and were identified as Mycobacterium szulgai, and the case was diagnosed as pulmonary atypical mycobacteriosis caused by M. szulgai. He was treated with isoniazid, rifampicin and ethambutol daily, but because of side effects, such as drug eruptions, all drugs were stopped. However, his clinical symptoms and infiltration shadow improved gradually. We described a rare case of pulmonary disease with Mycobacterium szulgai infection appearing in a healthy male without underlying diseases.
