Chronic eosinophilic pneumonia is a relatively uncommon condition associated with fever, malaise, weight loss, dyspnea, and hypoxia. The chest radiograph displays peripheral air-space consolidation, often referred to as the negative of pulmonary edema. The characteristic pathologic findings in the lung include marked accumulation of eosinophils in the alveolar spaces, often with the formation of eosinophilic abscesses. We report the history and pathologic findings in a patient who fit the clinical, radiologic, and pathologic features of chronic eosinophilic pneumonia, but who went on to develop cavitary atypical mycobacterial infection and died. We believe that this case represents an unusual response to an atypical mycobacterial infection.

Three cases of presumed respiratory syncytial virus (RSV) pneumonia in immunocompromised adults are described. Two patients had symptoms of cough, fever, and malaise, following completion of a course of combination chemotherapy for the treatment of acute lymphoblastic leukemia. The third patient, a juvenile onset diabetic, developed similar symptoms while hospitalized for severe hyperglycemia. Chest roentgenograms showed lower lobe infiltrates in both leukemic patients and a bilateral non-confluent bronchopneumonia in the diabetic patient. All patients had a marked rise in complement-fixing antibody titres to RSV, suggesting a concurrent infection with the virus. Extensive microbiological investigations failed to reveal any other etiologic agent. Nosocomial infection was considered possible. RSV is not considered a cause of pneumonia in compromised adults. Our three cases suggest that there may be a higher incidence of RSV pneumonia in compromised patients, than previously recognized.

Thirty patients with lung involvement with Pneumocystis carinii and other opportunistic organisms, many of whom also had Kaposi sarcoma, were seen from December 1980 through March 1982. Clinical manifestations consisted of a prodrome of weeks to months with weight loss, fever, and malaise. When clinical pneumonia became apparent, four distinct radiographic patterns were identified. Pneumocystis carinii was uniformly present, and the most common pattern encountered was a relatively symmetric, homogeneous perihilar pneumonia that progressed to diffuse consolidation. Asymmetric and focal infiltrates were seen in patients who proved to have concomitant opportunistic infection, most commonly fungal in all but two cases. A third pattern of nodular and linear densities with or without adenopathy was seen in patients without pneumonia who had biopsy-positive Kaposi sarcoma involving the lung parenchyma. A fourth pattern represented a combination of any of the first three, and these patients had multiple infections as well as Kaposi sarcoma in the lung. Any significant change in the radiograph indicating progression of disease while on therapy prompted a rebiopsy, and in five of 10 patients other infections and/or Kaposi sarcoma were identified.

Eight patients with Legionnaires' disease were seen at one hospital in the summer of 1979. They presented in the same 12-day period with an illness of rapid onset characterized by fever, chills, malaise, profuse sweating and neurologic symptoms. Neutrophilia, a high erythrocyte sedimentation rate, proteinuria, hypoalbuminemia, hyponatremia, hypochloremia and abnormal liver enzyme levels in the serum were usually noted. The roentgenographic findings in the lungs ranged from segmental interstitial infiltration to panlobar pneumonia. Seven patients responded to erythromycin treatment, though one died suddenly, presumably of unrelated cardiac disease. The other patient died of a combination of renal and respiratory failure, with pulmonary edema.

We described three cases of eosinophilic pneumonia of unknown aetiology investigated clinically and by lung biopsy. The illnesses lasted between six and 20 weeks and consisted of cough, dyspnoea, malaise, and in two cases prolonged pyrexia. All had blood eosinophilia and chest radiographs showing widespread bilateral shadowing; in two cases this had a characteristic peripheral distribution. One patient recovered spontaneously and the other two responded to steroids, with disappearance of pyrexia within 12 hours and radiological clearing within 14 days. Lung function tests during the acute illness showed volume restriction or gas transfer defects or both in two cases. After remission all three showed abnormalities if small airways function. Lung biopsies performed during the acute illness were examined histologically and by transmission electron microscopy, and in two cases by immunofluorescence. There was both intra-alveolar and interstitial eosinophilic pneumonia with bronchiolitis obliterans, microgranulomata, and a vasculitis. Electron microscopy showed numerous eosinophils, many degranulated, and macrophages with phagocytosed eosinophilic granules and intracytoplasmic inclusions. In one case IgM, IgG, and IgA were demonstrated in the bronchial walls and interstitium. No IgE or complement was present. We believe that eosinophil granules are responsible for the tissue damage and fever and suggest mechanisms for this and for the response to steroid therapy.

An explosive outbreak of influenza caused by an A/USSR/77-like (H1N1) virus occurred aboard a US Navy ship in December 1977 and January 1978. Two hundred volunteers aboard the ship were studied. Virus was isolated from 36 of 57 patients from whom isolation was attempted. Among virologically confirmed patients, headache (97%), chills (92%), malaise (86%), and cough (75%) were the most frequent symptoms. There were two virologically confirmed cases with complications: one with collapsed lung and the other with pneumonitis. The study subjects were 25 years of age or less, but there was little influenza-like disease in members of the crew greater than 25 years of age. Prior vaccination with bivalent vaccine, containing A/NJ/76 (Hsw1N1) virus, did not offer significant protection against disease caused by A/USSR/77-like virus. Serologic tests, either or both complement fixation and hemagglutination inhibition, were positive in only 14 of 22 virologically confirmed cases, indicating a poor serologic response to primary infection with this strain of virus. These findings prevented calculation of meaningful disease to infection ratios. However, inapparent infection occurred in 3 of 19 (16%) individuals who denied having illness during the outbreak yet had serologic evidence of recent influenza infection.

The antipyretic action of naproxen has been reported as sufficiently selective for neoplasm-related fever such that the use of this agent has been recommended to distinguish neoplastic from infectious fever. The antipyretic effect of naproxen was evaluated in gynecologic oncology patients with advanced pelvic malignancies and fever without obvious source of infection (suspected neoplastic fever). Naproxen (250 mg orally every 8 hr) was given to 12 patients with (i) a daily temperature greater than 38.3 degrees C, (ii) fever for at least 3 days, (iii) no evidence of infection on physical exam, (iv) negative results of blood and urine cultures, and (v) a chest roentgenogram negative for pneumonia. Ten of the 12 patients initially received a minimum of 3 days of empiric antibiotic therapy without resolution of fever. Within 24 hr of starting naproxen therapy, 10 patients' (83%) fever responded: Eight patients (80%) had a complete lysis of fever and two had partial lysis (20%). Temperature response was accompanied by subjective improvement in patient malaise and fatigue. Naproxen therapy was continued for 5-7 days in these patients, and chemotherapy was administered to those patients scheduled to receive it. Two patients did not respond to naproxen therapy in 24 hr; thus, it was stopped and the fever workup was continued. Of these two patients, one was eventually diagnosed with bacteremia after multiple negative blood cultures and initially no response to antibiotics. Naproxen is clinically useful in the palliation of fever-related symptoms in gynecologic oncology patients with suspected neoplastic fever. Naproxen may also allow the limitation of extensive fever workups and prolonged empiric antibiotic therapy in these patients, and prevent delays in systemic therapy or supportive care.

A 49 year old man with a long history of severe chronic asthma, treated with oral corticosteroids and weekly doses of methotrexate, contracted chickenpox from his son whose chickenpox rash had developed three weeks before presentation. Five days before admission the patient developed a vesicular skin rash which became extensive, with general malaise, bilateral pneumonia, and acute deterioration of his asthma. He died two weeks after admission despite treatment with acyclovir.

Sixteen adolescent specific pathogen free cats were inoculated with the Petaluma strain of feline immunodeficiency virus (FIV) and two cats were then necropsied at each of 5, 10, 21, 28, 42, 56, 70, and 84 day time points following infection. Lymphadenopathy gradually increased starting at Day 10 and persisted for the duration. Gross clinical signs of fever, mild to severe malaise, anorexia, diarrhea, dehydration, and generalized soreness appeared around Day 42, peaked at Day 56, and disappeared by Days 70-84 post-infection. Leukopenia, associated initially with a mild lymphopenia and later by both a mild lymphopenia and a severe neutropenia, appeared 14-28 days following infection, troughed at Day 56, and persisted thereafter. The CD4+:CD8+ T cell ratio started to decrease around Day 28, reaching a nadir at Days 56-70. This decrease was due to a decline in the absolute numbers and percentage of CD4+ T cells and an increase in the percentage of CD8+ T cells. Significant histopathologic lesions included myeloid hyperplasia between Days 56-70 post-infection; thymitis with cortical involution and follicular hyperplasia starting at Day 42; lymphoid hyperplasia of peripheral and mesenteric nodes, spleen and tonsils beginning around Day 42; typhlitis most evident from Day 56 onward, and an interstitial nephritis and pneumonitis that was most intense after Day 42. Virus was isolated from peripheral blood mononuclear cells (PBMC) beginning 2 weeks post-infection, and plasma viremia appeared 1 week later. Plasma and PBMC-associated viremia peaked at 42-56 days following infection and decreased abruptly thereafter. Proviral DNA was detectable as early as 5 days after infection in blood leukocytes and after 10 days in other organs. The central nervous system, lungs, thymus, tonsils and mesenteric lymph nodes were the earliest sites of virus localization. Antibodies to the FIV capsid protein appeared 14 days following infection and reached peak levels by Days 42-56. Abnormalities occurring during the primary stage of FIV infection were consistent with those described for acute simian and human immunodeficiency virus-induced disease.

A 77-year-old man was admitted because of high fever and general malaise. Whole-body CT showed large bilateral adrenal masses and para-aortic lymphadenopathy. Needle biopsy of the adrenal mass revealed mononuclear tumor cells within the lumens of small vessels, indicating the features of angioendothelial lymphoma. Immunohistochemically, these tumor cells were B cell lineage (positive for LCA, Mx-pan B, MB-1, and negative for factor VIII-related antigen, UEA-1, QB/ENDO 10). We used a modified CHOP therapy (500 mg of cyclophosphamide, 40mg of 4'-o-tetrahydropyranyl doxorubicin, 2mg of vindesine, and 50 mg of prednisolone) due to the patient's advanced age and general condition. Following the first course of this modified CHOP, the adrenal masses and para-aortic lymph nodes decreased dramatically in size, and his subjective symptoms also improved remarkably. Following three courses of modified CHOP, the patient developed dementia and disturbance of consciousness. Brain MRI revealed enhanced multiple nodular lesions. A diagnosis of multiple brain metastasis was made and modified CHOP and radiation therapy were begun, which relieved his symptoms for some time. However, he later died of pneumonia with severe leukopenia. A postmortem examination was performed. Microscopic examination showed no residual tumor cells in the adrenal gland. brain lymph nodes, or other organs. These results suggest that modified CHOP and radiation therapy may have beneficial anti-tumor effects against angioendothelial lymphoma.
