[A case of eosinophilic gastroenteritis: observation of serum IL-5 and sIL-2R levels before and after remission].

56 years-old man was admitted to our hospital because of severe diarrhea and hypereosinophilia. There was tenderness in the middle part of his abdomen. Laboratory examination revealed elevation of serum IL-5 and serum IL-2R value. No pathogens were detected from his stool specimen. An abdominal CT showed neither ascites nor thickening of intestinal wall. Pathological finding showed marked eosinophil infiltration in gastric and colonic mucosa. Eosinophilic gastroenteritis was diagnosed. His symptom was gradually improved spontaneously at the point of diagnosis. But administration of suplatast tosilate was stared because patients with this disease often relapse. Abdominal symptom was completely disappeared and value of serum IL-5 and sIL-2R was decreased at the end of September. This finding may imply pathogenesis of this disease.

[Clinical properties of community-acquired pneumonia in patients with asthma].

PURPOSE: Many reports were found on the clinical properties of community-acquired pneumonia. The clinical properties of community-acquired pneumonia in patients with asthma have not been elucidated, and we therefore investigated such properties. MATERIALS AND METHODS: Asthmatic patients who required hospitalization for community-acquired pneumonia from the beginning of 1989 through the end of 2001 were enrolled in this study. We performed the study in a retrospective manner. Patients were divided into two groups based on severity of their asthma (mild to moderate asthma vs severe asthma), and we studied the clinical properties of the pneumonia. RESULT: No significant difference was seen in body temperature, white blood cell counts, or CRP value on admission between the two groups. No significant difference was seen in the resolving period of the pneumonia. The frequency of common pathogens (Streptococcus pneumoniae + Haemophilus influenzae) was lower in patients with severe asthma. Asthmatic patients not taking daily oral corticosteroids were divided into two groups based on whether or not they were using a inhaled corticosteroid, and we examined the frequency of pathogendetection. The percentage of common pathogens was almost the same in the two groups. CONCLUSION: The frequency of common pathogens was lower in patients with severe asthma than in those with mild to moderate asthma. This fact is worth considering when empiric therapy for pneumonia is performed in patients with asthma. Inhaled corticosteroid therapy seems to have no influence on the pathogens of pneumonia in patients with asthma.

[Management of patients with bronchial asthma received general anesthesia and surgical intervention].

Stimulation to bronchial mucosa is one of the major risk factor of asthma attack. When patients receive surgical intervention and general anesthesia, they are always exposed to stimulation to bronchial mucosa. Prevention method of bronchial asthma attack during surgical intervention is not established yet. We investigated that clinical course of patients with bronchial asthma who received general anesthesia and surgical intervention. Seventy-six patients with bronchial asthma were received general anesthesia and surgical intervention from 1993 to 1998. Twenty-four patients were mild asthmatic patients, 39 were moderate asthmatic patients and 13 were severe asthmatic patients. Preoperative treatment for preventing asthma attack was as follows; Eight patients were given intravenous infusion of aminophylline before operation. Fifty-two patients were given intravenous infusion of aminophylline and hydrocortisone before operation. Three patients were given intravenous infusion of hydrocortisone for consecutive 3 days before operation. Thirteen patients were given no treatment for preventing asthma attack. One patient was suffered from asthma attack during operation. She was given no preventing treatment for asthma attack before operation. Three patients were suffered from asthma attack after operation. No wound dehiscence was observed in all patients. To prevent asthma attack during operation, intravenous infusion of steroid before operation is recommended, when patients with asthma receive general anesthesia and surgical intervention.
