There were two cases of fatal interstitial pneumonia secondary to bleomycin sulfate administration. Although bleomycin pulmonary toxicity is generally thought to be dose-related and occurs infrequently with a total cummulative dose less than 300 to 400 units, the two reactions reported here occurred with doses of 105 and 165 units. Fatal bleomycin-induced pneumonia has been previously reported at these low dosages, and physicians should be aware that this toxic reaction may occur as an idiosyncratic response. Previous thoracic irradiation may be a predisposing factor. Patients receiving bleomycin should be meticulously monitored by interrogation for cough, dyspnea, and chest pain; by auscultation for rales; by serial chest roentgenograms; and by determinations of vital capacity and single-breath carbon monoxide diffusing capacity.

One-shot intratumor injection of 60 mg oil-bleomycin prior to subtotal esophagectomy induced fatal, acute interstitial pneumonitis in a 53 year-old esophageal circinoma patient. The progression of bleomycin-induced pneumonitis was rapid and the patient succumbed to respiratory insufficiency 41 days after surgery (58 days after bleomycin administration). Autopsy revealed bilaterally increased lung weight and the organ was of rubbery consistency and anthracotic. Histology showed advanced interstitial fibrosis, numerous lymphocytes in alveolar septi and fibrinous exudate, macrophages and desquamative cells within the alveolar spaces. In the present case, pneumonitis was due not to patient age or dosage level of bleomycin, but rather to the administration method.

The intratracheal administration of highly purified Pseudomonas aeruginosa proteases (ca. 10 to 100 microgram) elicited extensive, grossly observable rabbit lung damage by 3 h postinjection. Light and electron microscopic characterization of the lesions revealed: (i) progressive injury and necrosis of type I epithelial cells and capillary endothelial cells from 3 h to 1 day postinjection, and progressively increasing accumulations of erythrocytes, plasma proteins, fibrin, and released type II epithelial cell lamellar bodies in alveolar lumina during that time period; (ii) progressively increasing accumulations of macrophages, but not of polymorphonuclear leukocytes, in alveolar lumina from 3 h to 6 days postinjection; (iii) progressive hyperplasia of type II epithelial cells from 12 h to 4 days postinjection; (iv) progressive infiltration of alveolar septa by mononuclear inflammatory cells (interstitial pneumonitis) from 2 to 6 days postinjection; (v) no loss of alveolar septal connective tissue and no damage to pulmonary arterioles and venules; and (vi) almost normal alveolar structure by ca. 8 days postinjection. The study revealed that the intra-alveolar hemorrhage, the injury and necrosis of alveolar septal cells, and the infiltration by mononuclear cells that have been reported to occur during human pseudomonas pneumonia can also be elicited by the experimental administration of pseudomonas proteases. Thus, the results support the idea that in vivo production and activity of P. aeruginosa proteases is important, at least in part, in eliciting the lung damage characteristic of pseudomonas pneumonia.

Acute lupus pneumonitis was the presenting manifestation of systemic lupus erythematosus in six of 12 cases in this series. The clinical picture was characterized by severe dyspnea, tachypnea, fever and arterial hypoxemia. Radiographic findings included an acinar filling pattern which was invariably found in the lower lobes and was bilateral in 10 of the cases. Studies failed to reveal evidence of infection as a cause of the acute pulmonary infiltrates. All patients were treated with oxygen and corticosteroids; seven received azathioprine. Six patients survived and are clinically well 14 months to four years following their acute illness. Three of these patients have residual interstitial infiltrates with persistent pulmonary function test abnormalities indicating progression to chronic interstitial pneumonitis. Histologic sections of the lungs available from four patients revealed hyaline membranes and interstitial edema (four cases), acute alveolitis (two cases), arteriolar thrombosis (one case) and a prominent lymphocytic interstitial pneumonitis with organizing bronchiolitis (one case).

The present paper reports a study on 27 children who died of interstitial pneumonia due to Pneumocystis carinii in the clinics of pediatrics, Cluj, in the course of 3 years (1971-1973). The incidence was 10% of the children who died from acute pneumonia. The authors show the morphopathologic possibilities of identifying the pictures modified by plasmocytic pneumonia due to association of the disease with bacterial and viral infections. These cases represent a quarter of the authors' cases. The importance of being acquainted with these altered pictures, illustrated in the text, is emphasized.

A case of pneumonia associated with acute CMV infection is reported. A 34 year-old man was admitted with fever (39 degrees C equals 102.2 degrees F), malaise and dyspnea. Clinical findings were characteristic of viral pneumonia. Crepitant rales to chest auscultation were heard all over the lung. X-ray picture showed evidence of interstitial pneumonia. Leucocyte counts were normal whilst lymphocyte counts elevated. Bone marrow examination showed an increase of lymphocytes and lymphoblasts. To palpation liver and spleen were slightly enlarged. Liver function tests were slightly abnormal. Bacteriological tests on urine and blood and Paul-Bunnel test were negative. Antibiotic therapy was ineffective. CMV was isolated from saliva and urine. Serological studies (elevated CF and precipitin antibody titer) suggested the diagnosis of a CMV infection. The patient recovered in 3 weeks.

An outbreak of acute severe pneumonia which affected six to 14-week-old single-suckled calves, resulted in 45/77 requiring treatment. The examination of paired sera from all affected calves revealed that neither an adenovirus, non infectious bovine rhinotracheitis virus nor parainfluenza 3 virus was involved. The acute exudative interstitial pneumonia found at post mortem was typical of pneumonic pasteurellosis.

The pathogenicity of a strain of simian herpesvirus SA8 in one month old conventional and gnotobiotic baboons was investigated. Intratracheal inoculation resulted in a mortality rate of 1/5 in the conventional and 1/4 in the gnotobiotic group. Disease became apparent after 3 days and was characterized by respiratory distress, reduced formula intake, weight loss and fever in both groups. Isolation of herpesvirus from the respiratory tract, lymphoid organs, kidneys, adrenals, and CNS was more frequent by explant culturing than by routine procedures. Although there was a significant difference in total white blood counts (WBC), with higher values in conventional vs. gnotobiotic infants, the absolute number of lymphocytes was not different. The lower number of WBCs apparently was due to fewer polymorphonuclear leukocytes in the gnotobiotic baboons. Infection resulted in a leukopenia 5 days post infection (p.i.) and a leukocytosis 10 days p.i. in both groups. The animals, which succumbed, had acute necrotizing fibrinous pneumonia. Intranuclear inclusion bodies typical for herpesviruses were present. All the surviving infant baboons had subacute interstitial pneumonia, when sacrificed 35 days p.i.

Into 14 juvenile cebus monkeys that lacked serum antibodies for RS virus 10(8) plaque-forming units (pfu) of wild-type respiratory syncytial (RS) virus were inoculated transtracheally. Roentgenographic evidence of pneumonia developed in 13 of 14 infected animals. Gross pathologic changes occurred in each of the 13 monkeys that were sacrificed. Patchy areas of red consolidation were seen in the lower lobes 24 hours after inoculation, and there was progression to gray consolidation seven days later. Each of the infected animals had histologic evidence of interstitial pneumonia. Changes were detected in the lung as early as 24 hours after inoculation; they consisted primarily of infiltration of the alveolar wall. By the fourth to sixth day after inoculation there was marked interstitial thickening, pulmonary consolidation, formation of multinucleated giant cells and development of eosinophilic cytoplasmic inclusion bodies within alveolar cells. RS viral antigens, detected by indirect immunofluorescence, were distributed throughout cells of the alveolar wall and the bronchiolar epithelium. The virus grew to highest titer in the lungs on the fourth to sixth day after inoculation; up to 10(8) pfu/gram of tissue were detected. The cebus monkey represents the first experimental host to develop extensive pulmonary lesions during infection with respiratory syncytial virus.
