Generalized but well-circumscribed lymphadenopathy and rash-like skin changes were observed in three men, aged 58 to 75 years. There was a reticular appearance in the chest X-ray.
Dyspnoea
, weakness, marked weight loss, changing but marked
lymphopenia
, markedly increased blood-sedimentation rate, and an always negative Tine test were present in all three. Despite antibiotics, cytostatic drugs and prednisolone the disease quickly ended fatally with high fever, general debilitation and pneumonia. Post-mortem examination revealed diffuse lymphatic hyperplasia with plasma-cell infiltration in the lymph nodes, tonsils and lymphatic tissue of the intestines, and diffuse hyperplasia of the endothelial venules, together with basophilic blast cells, eosimophilic granulocytes and reticulum cells with broad nucleoli. The spleen was normal or enlarged. Spleen, lung tissue and lymphatics, the skin in the area of the small vessels, hair follicles and sweat glands contained lymphocytes, plasma cells and eosinophilic leucocytes. The spleen, if enlarged, also had focal necroses in its periarteriolar septa. In two cases electrophoresis revealed beta-globulin poorly demarkated from gamma-globulin, doubling and increase. In the third case, IgA was markedly increased with one each monoclonal IgG1 und IgA, and corresponding shift in the chi/lambda relationship in serum. Immunohistologically, lymphocytes were made up of about 20 percent IgG-containing and about 25 percent IgA-containing cells.
Lymphopenia
, if present, was associated with markedly reduced blast transformation of peripheral lymphocytes to phytohaemagglutinin. The granulocytes were defective (intracellular killing of Candida albicans and Staphylococcus aureus), while the nitrobluetetrazolium test was normal. There was RBC phagocytosis in the macrophages of bone marrow and in Kupffer cells of all three cases.

Ten of 70 children (14%) with acute lymphoblastic leukemia developed severe interstitial pneumonitis within three weeks after induction of central nervous system prophylactic therapy. The clinical picture was characterized by fever, cough, progressive
dyspnea
, and hypoxemia with complete resolution in one to three weeks, except in one patient who died during the acute illness from respiratory failure. P. carinii organisms were found in the lung tissue of only one patient. The etiology of the pneumonitis in the other nine children was probably viral, acquired or activated during a period of
lymphopenia
and immunosuppression. The morbidity and potential mortality from the pneumonitis warrants early recognition by open lung biopsy and intensive supportive therapy.

To establish an animal model of AIDS, two different "wild" or "adapted" HIV2 Rod and Eho strains were cultivated on monkey cells from different species (baboons, cynomolgus, Rhesus monkeys). Five different available strains were then injected both by intravenous (i.v.) and intracerebral (i.c.) route into ten Rhesus monkeys. Seven animals seroconverted between days 13 and 230. Reverse transcriptase activity in the lymphocyte culture supernatants was detectable in six of the seven animals that seroconverted, and in one animal that remained seronegative.
Lymphopenia
and a decrease in the CD4+ cell counts were observed in eight animals. One animal, inoculated with HIV2-Rod "wild type," developed a severe cachexia, with
dyspnea
, and associated neurological symptoms 150 days after inoculation. This animal was sacrificed on day 220. Pathological examination showed typical lesions of actinomycetes infection in the lungs and in the meninges. Another monkey had significant weight loss associated with lymphadenopathies and pancytopenia. These results suggest that in vivo replication of HIV2 in Rhesus monkeys may induce clinical symptoms of immune deficiency. This method is reproducible and may provide a good model for AIDS.

Seventy nine cases of sporadic, community acquired legionnaires' disease have been reviewed. Annual and seasonal variation in incidence was noted. The mean age of the patients was 53 years and 50 (63%) were male. Pre-existing chronic diseases were present in only 23 (29%), including two patients receiving immunosuppressive treatment. Common symptoms included unproductive cough,
dyspnoea
, chest pain, headache, confusion, nausea, vomiting, and diarrhoea. Respiratory symptoms were absent, however, in 17 (22%). Localising chest signs were present in 74 (95%) cases. Frequent laboratory findings included
lymphopenia
, high erythrocyte sedimentation rate, hyponatraemia, raised urea and creatinine concentrations, abnormal liver function, hypophosphataemia, hypoalbuminaemia, proteinuria, and haematuria. Thirteen patients died (16%), including nine of 20 who received assisted ventilation. The mortality rate in patients treated with erythromycin (11%) was lower than in those who received other antibiotics (23%), but this difference was not statistically significant. Of the features noted on admission, only a high plasma urea concentration was significantly associated with death. Sporadic community acquired legionnaires' disease is a not uncommon disorder, which with appropriate treatment has a prognosis similar to that of other forms of community acquired pneumonia.

Use of methotrexate to treat rheumatoid arthritis is associated with pulmonary adverse effects in 3% to 5% of cases. In addition to immunoallergic lung disease, bronchitis and pneumonia due to pyogenic organisms, opportunistic lower respiratory tract infections have been reported, including, to our knowledge, 18 cases of Pneumocystis carinii pneumonia. We report two new cases of P. carinii pneumonia in methotrexate-treated rheumatoid arthritis patients. One case occurred in a 62-year-old woman with a nine-year history of seropositive rheumatoid arthritis treated for the last seven months with methotrexate, 15 mg per week, and prednisone, 10 mg/d. The other patient was a 58-year-old woman who had been diagnosed with rheumatoid arthritis 18 months earlier and had been receiving 15 mg per week of methotrexate for eight months in combination with 12.5 mg of prednisone per day. Both patients had negative tests for the human immunodeficiency virus. Symptoms consisted of fever, cough and
dyspnea
, with interstitial infiltrates on chest films, hypoxia, and
lymphopenia
(700 and 600/mm3, respectively). The diagnosis was confirmed by bronchoalveolar lavage. Both patients recovered under treatment with trimethoprim-sulfamethoxazole. An analysis of the 20 cases of P. carinii pneumonia reported to date in methotrexate-treated rheumatoid arthritis patients demonstrated a number of characteristics: the rheumatoid arthritis was of recent onset in some cases (a few months in one patient);
lymphopenia
was present in two thirds of cases; one-third of patients were not receiving corticosteroid therapy; the dosage and duration of methotrexate therapy varied widely, from 5 to 30 mg per week and two to 48 months; and four patients died.

A 67-year-old male was hospitalized because of nonspecific symptoms and bilateral pleural effusions. He gave no history of cough,
dyspnea
or thoracic pain. The blood counts showed moderate anemia and high-grade
lymphopenia
. The tuberculin test and the anergy-panel were both negative. Testing for HIV was negative. Analysis of pleural fluid showed an exudate with 47% lymphocytes and absence of acid-fast bacilli on Ziehl-Neelsen smear. On histologic examination, the pleural tissue showed no evidence of granuloma. However, cultures for mycobacteria of pleural tissue yielded M. tuberculosis. In this case of pleural tuberculosis, leading symptoms were absent and the tuberculin test was negative in the presence of active tuberculosis. In addition, the cells in the pleural effusion were not predominantly lymphocytic. Patients presenting with unclear effusion should undergo extensive investigations, including a tuberculin test, and anergy panel, pleural fluid cultures, and pleural biopsy with cultures for microorganisms, with the object of establishing or ruling out pleural tuberculosis.

A 46-year-old man was admitted to our clinic because of acute heart failure. Six years before admission he was pointed out cardiomegary and hematuria. One year later, he was diagnosed as having jugular foramen syndrome. On admission, he had a fever and
dyspnea
. Pansystolic blowing murmur was audible at the apex. The chest ratio on his chest X-ray was 52.5%. An electrocardiogram showed left ventricular hypertrophy. An echocardiogram showed marked dilatation and severe dysfunction of left ventricle. Radionuclide scanning with technetium 99 m pyrophosphate identified inflammatory change in the apex. Myocardial biopsy showed fibrotic degeneration and IgG deposits in myocardium. Blood examination showed anemia,
lymphopenia
. positive anti-nuclear antibody (1000 times, shaggy pattern), positive anti ds-DNA antibody and hypocomplementemia. Furthermore, proteinuria was pointed out. Renal biopsy showed focal segmental glomerulonephritis with active necrotizing lesion (type III nephritis). Lupus myocarditis and nephritis was diagnosed. After prednisolone (80 mg/day) was administered. left ventricular function and hypocomplementemia improved. The ACE inhibitor was also used for proteinuria. In spite of a little amount of blood transfusion, he showed hepatic hemosiderosis. We suspect that the cause of hemosiderosis was related chronic inflammation of active lupus. It was treated with Erythropoietin.

Antibody-based treatment is a novel, effective management strategy for a variety of diseases. Alemtuzumab (CAMPATH) is an example of a monoclonal antibody (mAb) that was initially developed in the laboratory and has completed its journey by being approved for therapeutic use in humans. The main clinical applications of alemtuzumab include treatment of lymphoid malignancies, particularly chronic lymphocytic leukaemia (CLL) and T-cell prolymphocytic leukaemia (T-PLL) and prevention of graft versus host disease (GVHD) and graft rejection in bone marrow and solid organ transplant recipients. Alemtuzumab administration is accompanied by a characteristic first-dose reaction due to cytokine release that consists of fever, rigors, rash and, at times,
dyspnea
and hypotension. The most significant toxic effect is profound, prolonged
lymphopenia
and the subsequent increased risk of opportunistic infections; antibiotic prophylaxis is recommended for patients undergoing alemtuzumab treatment. Alemtuzumab has demonstrated clinical activity as a single agent and has an acceptable toxicity profile. It has significant therapeutic potential, especially against lymphoid malignancies.

The mysterious severe acute respiratory syndrome (SARS) that has originated from the southern Chinese province of Guangdong appears to be a major public health threat and medical challenge. Laboratory studies of SARS patients in a number of countries identified the etiologic agent being a novel member of coronaviridae. High RNA concentrations of this virus in sputum make it as a highly infectious agent. Low concentrations of viral genome are also detectable in feces. Coronaviruses are ubiquitos. They cause disease in many animals including pigs, cattle, dogs, cats, and chickens. These viruses have been associated with upper respiratory infections and sometimes pneumonia in humans. SARS presents with fever, cough, malaise,
dyspnea
, and hypoxemia. Chest radiographs from affected regions are associated with progressive airway disease. Clinical laboratory features of SARS include
lymphopenia
, thrombocytopenia, and elevated lactate dehydrogenase levels. Currently, there is no FDA approved pharmacologic treatment for SARS. To date, no convincing clinical data is available for treatment of SARS with ribavirin. While there are some controversies about the use of systemic corticosteroids, Martin et al, in this issue of MSM, present their views on the use of pentoxyfylline (PTX) as a potential agent to be considered for SARS treatment. Finally, our analytical approach to the risks of SARS will certainly enable us to

The aim of this paper was to compare the effect of flumethasone and meloxicam in combination with oxytetracycline on clinical and immunological parameters of calves suffering from enzootic bronchopneumonia. The study was performed on 30 Black-and-White Lowland Breed calves with clinical signs of enzootic bronchopneumonia divided randomly into three equal groups and, respectively, treated with-Group I: oxytetracycline and meloxicam; Group II: oxytetracycline and flumethasone; Group III (control): oxytetracycline only. Treatment of calves with the combination of oxytetracycline and meloxicam (Group I) caused a significantly faster, in comparison to other groups, improvement in the clinical illness index score (CIIS: cough, nasal discharge,
dyspnea
, depression and anorexia) and a faster normalization of body temperature. A slow decrease in white blood cell (WBC) count, the number of neutrophils, MID (mixed number of monocytes, eosinophils and basophils) and in the individual number of monocytes (CD14/CD45 positive cells) was observed in Groups I and III. In the blood of the calves which received oxytetracycline and flumethasone (Group II), leukocytosis, neutrophilia and monocytosis with concomitant
lymphopenia
and a low number of T cells (CD2+) was observed. Moreover, the calves treated with flumethasone exhibited a decrease in gamma-globulin concentration, and phagocytic parameters. Both drugs, flumethasone and meloxicam slightly decreased tumor necrosis factor (TNF) but meloxicam slightly increased the levels of interferon (IFN) in sera and in bronchoalveolar lavages (BALs). These results suggest that the combination of meloxicam with an antibiotic in calves suffering from enzootic bronchopneumonia is superior to the antibiotic alone and also to the combination of the antibiotic with flumethasone.
