A 70-year-old woman was hospitalized for status asthmaticus. The level of CRP was high and chest roentgenogram showed infiltrative shadows in the left middle lung field. Artificial respiration and continuous infusion of methylprednisolone and aminophylline 750 mg/24 hr were performed. Eight hours after admission, seizures suddenly occurred. At this time, brain CT showed no abnormal findings. The seizures were thought to be induced by theophylline toxicity, since serum theophylline concentration was high at 69.9 micrograms/ml. Because theophylline clearance of the patient in a clinically stable condition was normal, it was speculated that theophylline clearance was reduced during status asthmaticus. It is thought that this rare case of theophylline toxicity occurred due to reduction of theophylline clearance during status asthmaticus associated with pneumonia.

A 47-year-old woman was admitted to our hospital because of dry cough and throat discomfort. Chest X-ray film showed reticular shadows with Kerley B line and scattered nodular shadows. Blood examination revealed normal WBC count (5100/mm3) with eosinophilia (21%), negative CRP, elevated ESR (49 mm/l hr), normal IgE level and positive antinuclear antibody with speckled pattern. Skin tests and precipitating antibodies for common allergens were negative. Results of arterial blood gas analysis and respiratory function test were almost normal. Bronchoalveolar lavage fluid yields 85.7% eosinophils, which suggested eosinophilic lung disease. To establish the diagnosis, thoracotomy was performed and lung specimens were obtained from S3a and S8a. In the area of the nodule, the alveolar spaces were filled with eosinophils and mononuclear cells, with no evidence of vasculitis, granuloma or parasites. Alveolar spaces were almost preserved in residual areas. The walls of air ways, pleura and lobular septa were heavily infiltrated with eosinophils and mononuclear cells. Thus, open lung biopsy confirmed the diagnosis of idiopathic eosinophilic pneumonia. The areas of intraalveolar filling with eosinophils and mononuclear cells were found to correspond to the nodular shadows on chest X-ray film. The relationship between the findings of chest X-ray films and lung histology are discussed.

Among 61 patients admitted to our hospital because of bacterial pneumonia during the last six years, we investigated several risk factors influencing delayed resolution of pneumonia shadows, such as age, extent of the lesion, period of fever and sputum production after antibiotic therapy, WBC, CRP and PaO2 values on admission, the period of increased values of WBC and CRP, the presence or absence of etiological pathogens, the period from the appearance of symptoms to admission, and the period of drug therapy. In our series, the period from appearance of symptoms to admission (r = 0.62) and that of increased WBC (r = 0.35) significantly correlated with the period of pneumonia shadows to the time of their resolution. Similar results were obtained from the multiple variate analysis of various factors. These results suggest that the duration period (nontherapy period) of inflammation closely associated with leukocytosis plays a crucial role in the delayed resolution of pneumonia shadows.

Between 1976 and 1990, 208 cases of bacteremia in our department were studied. Community acquired bacteremias were only 18 (8.7%) cases. Bacteremias, particularly caused by Gram positive organisms, increased significantly after 1981, compared with the first five years. It was related to the marked increase in cases of venous access devices and less sensitivity of the Gram positive organisms to the new cephem antibiotics. In the study, 144 (69.2%) cases were eradicated. Severe underlying diseases or complication of pneumonia influenced the eradication rate of bacteremia. Bacteremia caused by methicillin resistant Staphylococcus aureus or Pseudomonas aeruginosa showed poor prognosis. The average duration from onset to death, was 5.1 days. Forty cases (62.5%) died within 3 days. Among the 201 cases, leukocytosis (WBC greater than 10,000/mm3) was present in 38.3%, while leukopenia (WBC less than 1000/mm3) in 25.3%. Eradication rate between the two groups was not significant. CRP was elevated (greater than 8.5 mg/dl) in 63.5%. The prognosis of this group was significantly poor. Elevation of serum bilirubin was also related with increase of mortality. According to these results, empiric therapy before the isolation of organisms is the most important strategy for treatment of bacteremia.

Moraxella subgenus Moraxella sp. was isolated in pure culture from the sputum of a 43-year-old male with pneumonia and congestive heart failure due to idiopathic dilated cardiomyopathy. In this case, we concluded that the patient's bacterial pneumonia was caused by M. (M.) sp. based on a Gram stain of the sputum smear and bacterial findings, increased WBC count, and elevated CRP. A chest X-ray revealed right middle, and left upper and middle lobe infiltrates. This Moraxella strain produced a BRO-type beta-lactamase, a carbenicillinase-type enzyme.

The pathophysiologic significance of vitronectin in bacterial pneumonia was studied. The following conclusions were obtained. 1) Plasma vitronectin in healthy persons was 252.3 +/- 65.2 micrograms/ml. The level was markedly decreased to 167.0 +/- 42.7 micrograms/ml in patients with bacterial pneumonia. However, it was gradually increased to the normal levels as recovering with pneumonic lesions. It was also found the negative correlation between plasma vitronectin and CRP (r = -0.7) and plasma fibrinogen (r = -0.6) in the course of pneumonia. 2) Vitronectin was localized on elastic fibers of the basement membrane of bronchial epithelium, the alveolar interstitium and the blood vessels in normal lung tissue by immunohistochemical method. On the other hand, vitronectin was significantly localized on inflammatory sites, in particular, fibrin matrix and fibrous sites in pneumonic lesions. These findings were more dominant in severe pneumonia. The results are suggested that reducing in plasma vitronectin appears to be depended on the vitronectin consumption in pneumonic site. 3) In in vitro experiments, activating PMNs, alveolar macrophages and pulmonary fibroblasts were easy to adhered to vitronectin. This adhesiveness to vitronectin was also observed in the strains of S. pneumoniae, S. aureus, and P. aeruginosa, but not in K. pneumoniae and E. coli. These results suggest that vitronectin plays an important role for host defense mechanism by mediating to cell-bacteria interaction and it promotes the recover of injured tissue by induction with pulmonary fibroblasts.

Aspergillus infection is the most frequent fungal infection associated with chronic granulomatous disease (CGD), and often results in a life-threatening situation. This report describes the use of high-dose fluconazole, a new antifungal agent, for invasive Aspergillus infection in a patient with CGD. A 27-month-old boy was sent to our hospital because of unknown fever in October, 1988. He was then admitted for pneumonia and pleural effusion of the right lung in February, 1989. Treatment with antibiotics was ineffective, and cultures of throat and pleural fluid were negative. In May, 1989, Aspergillus fumigatus was cultured from a subcutaneous abscess at the point of pleural puncture. Therefore we speculated that Aspergillus might have been the cause of pneumonia. The patient was diagnosed as having CGD by NBT test. Treatment with miconazole, flucitocin and amphotericin-B syrup was ineffective. From July, 1989, he was given 100 mg/day fluconazole d.i.v., but the drug did not reach an effective serum concentration to combat Aspergillus. However, an effective concentration of fluconazole was reached at a dose of 250 mg/day, and the chest X-ray findings subsequently improved, despite occasional high fever and continued high CRP. In July, 1990, the route of fluconazole administration was changed from d.i.v. to p.o. at the same dose, resulting in a serum concentration of fluconazole higher than that achieved with d.i.v. treatment. Both the clinical and laboratory findings showed improvement thereafter. Therapy for Aspergillus infection associated with CGD was found to necessitate high doses of anti-fungal drugs over a long period, although treatment with previously employed anti-fungal drugs could not be continued due to their adverse side effects.(ABSTRACT TRUNCATED AT 250 WORDS)

Liver disorders were reviewed in 76 patients with mycoplasma pneumoniae pneumonia (MP) admitted to Kamo Hospital from 1979 to 1989. Liver dysfunction was detected in 16 patients (21%). Liver disorder were detected in 10% of MP from 1979 to 1980, but in 20% from 1984 to 1985, and in 36% from 1988 to 1989. By multiple regression analysis CRP was found to be the most significant factor among other factors such as prevalence, age, sex, history of smoking, history of drinking, and days after onset of fever.

Listeriosis of the newborn is a relatively rare disease, presenting with clinical signs of septicemia. Early onset disease, resembling group B streptococcal septicemia, is already transmitted from the mother to the fetus and is associated with high morbidity and mortality. Late onset septicemia occurs as sporadic or as epidemic disease, usually beyond the fifth day of life. Epidemics can be caused by consumption of contaminated food or by nosocomial infections in neonatal units. Phage typing offers an opportunity to elucidate the route of transmission. During a 7 years period, 5 neonates ware diagnosed to have early onset, 1 newborn to have late onset Listeriosis. They all showed signs of bacterial septicemia with typical changes of white blood cell count, elevated CRP, hepatomegaly, and severe pneumonia. In all patients Listeria monocytogenes could be isolated from blood cultures. Serological tests were negative in all cases. 3 patients died. Nosocomial transmission of Listeria monocytogenes from one infant to another was proven by phage typing.

A 58 year-old man was admitted to our hospital with complaints of dyspnea and cough. Chest X-ray examination revealed diffuse nodular shadow, infiltration in the left upper and lower lobes, and volume loss. BALF showed increased number of cells, particularly eosinophils (65.6%). Eosinophilia (17-13%) was also seen. The histological examination of the TBLB specimen revealed irregular thickening and edema of alveolar septa. From these findings together with clinical features the case was diagnosed as eosinophilic pneumonia. Oral administration of prednisolone started with 30 mg. Within a week, eosinophilia in peripheral blood decreased to 1%, PaO2 increased to 87.5 Torr in room air, and CRP became negative. His chest X-ray film showed the disappearance of infiltrative shadows in the left upper and lower lobes. On the 19th day was prednisolone decreased to 20 mg. Laboratory data and chest roentgenogram showed exacerbation, and PaO2 gradually decreased to 62.9 Torr. Patchy shadows were seen in the right upper lobe. The dose of prednisolone was again increased to 60 mg/day, and was quite effective. The drug dosage was tapered by 10 mg/10 days to 40 mg/day, however all data exacerbated again. The clinical course seemed peculiar for eosinophilic pneumonia, however small reticulonodular shadows on chest X-ray did not change. Therefore, open lung biopsy was performed. The histology of the specimen showed fibrosis, lymphocyte infiltration and thickening of alveolar septa. The clinical course and histopathological findings led to a diagnosis of idiopathic pulmonary fibrosis accompanied with chronic eosinophilic pneumonia.
