S-6437 (Sustained release cephalexin granule for pediatric use) was studied with the following results: 1) Following the single oral administration of 25 mg/kg of S-6437 in 6 children 4 approximately 6 years old, the following blood levels (average) of cephalexin were obtained: 3.1 microgram/ml in one hour after the administration, 8.6 microgram/ml in 2 hours, 8.7 in 4 hours, 7.2 in 6 hours, 4.0 in 8 hours and 1.2 in 12 hours. Effective blood levels of cephalexin by S-6437 were maintained for longer period of time than those by regular cephalexine dry syrup. In 4 of 6 children receiving S-6437, cephalexin was scarcely detected in their blood in 12 hours after the administration. From this, it is not considered that S-6437 is accumulated in body. 2) S-6437 was administered to 38 patients including: 7 with pneumonia, 7 with acute bronchitis, 1 with suppurative lymphadenitis, 4 with acute pharyngitis, 15 with acute tonsillitis and 4 with acute urinary tract infections. Out of the 35 cases, 31 (88.6%) responded to S-6437, and 3 cases could not be evaluated. 3) Transient diarrhea in 2 patients, rash in 1 and elevation of serum GOT, GPT and LDH in 1 were observed. However, these side effects were improved by discontinuation of S-6437.

PC-904 was administered to 24 patients: urinary tract infections (7 cases), bronchitis (2 cases), pneumonia (3 cases), brain abscess (1 case), septicemia and the suspected cases (10 cases), and buttock abscess (1 case). The daily dosage varied from 60 to 223.4 mg/kg and averaged 86.9 mg/kg. The drug was administered three times a day by 1-hour drip infusion, and the duration of the treatment averaged 11 days. Clinical results were obtained as excellent responses in 5 cases, good in 13, poor in 4, and unknown in 2, giving 75% of the clinical effectiveness. Bacteriological responses were excellent in 7, good in 2, poor in 2, and unknown in 13, and the overall effectiveness was evaluated as excellent in 2, good in 17, and unknown in 5. Antibacterial activities against clinically isolated bacteria were examined. MIC values of PC-904 were over 100 mg/ml 1 strain of E. coli and 2 strains of Klebsiella, however excellent sensitivities were observed in 3 strains of Ps. aeruginosa and MIC values varied 1.56 to 3.12 microgram/ml at 10(8) of inoculum size and 0.78 to 1.56 microgram/ml at 10(8). As to side effects, diarrhea was observed in 1 case, rash in 2, lowering ob blood pressure in 2, elevation of GOT in 1, and elevation of LDH in 2. Abnormal elevations of GOT (10 cases), GPT (5 cases), A1-P (1 case), LDH (7 cases), and BUN (1 case) were noticed in other patients, but it was considered to be due to underlying diseases.

Radioimmunoassay of 5alpha, 7alpha-dihydroxy-11-keto-tetra-norprosta-1,16-dioic acid, main urinary metabolite of prostaglandin F2alpha (PGF2alpha-MUM), was performed in patients with various respiratory diseases including diffuse interstitial fibrosing pneumonitis (DIFP, fibrosing alveolitis). Twenty-four hr excretion of PGF2alpha-MUM in patients with primary lung cancer, pulmonary fibrosis secondary to collagen diseases and stationary DIFP was normal. On the other hand, 24 hr excretion of PGF2alpha-MUM in patients with carcinomatous pleuritis was high and that in patients with aggravating DIFP was markedly high. There was no correlation between serum LDH levels and 24 hr excretion of PGF2alpha-MUM.

To determine the sensitivity of serum KL-6 and serum lactate dehydrogenase for detecting the contraction of radiation pneumonitis, 15 patients with lung cancer who had radiation therapy were monitored. Six of the patients contracted radiation pneumonitis (pneumonitis group) and the other patients did not (control group). Serum levels of KL-6 were significantly (p less than 0.05) elevated according to the complication of radiation pneumonitis in all patients of the pneumonitis group. In the control group, however, one-sided changes of KL-6 level were not observed. In the pneumonitis group, serum LDH levels were not significantly changed. However, there was a strong correlation between the altered levels of KL-6 and those of LDH (r = 0.992). These observations indicate that the same cytopathologic changes may cause the elevation of serum KL-6 level and the elevated activity of serum LDH in the patients with radiation pneumonitis, and that KL-6 is much more sensitive than LDH for detecting radiation pneumonitis.

A 78-year-old man was admitted to the Nishinomiya Municipal Central Hospital with main symptoms of chest pain and dyspnea. Chest CT revealed a large mediastinal mass shadow, and echocardiography revealed pericardial effusion. Serum LDH was elevated. Therefore, malignant lymphoma was suspected to be the cause of cardiac tamponade. VEPA chemotherapy was commenced. Half way through the course of chemotherapy, serum LDH was decreased, the pericardial effusion had disappeared, and the mediastinal mass was reduced in size. A biopsy specimen of the mediastinal tumor revealed malignant lymphoma of diffuse large cell type, and immunoperoxidase staining of frozen sections demonstrated B cell origin. The pericardial effusion had not increased in size after four months, when the patient developed pneumonia and died. Autopsy revealed pericardial and atrial involvement by tumor. In conclusion, this case is very unusual in that (1) pericardial involvement was suspected on admission; (2) the pericardial effusion disappeared with systemic chemotherapy; and (3) cardiac metastasis was demonstrated at autopsy.

It has been previously demonstrated that serum lactate dehydrogenase is elevated among HIV patients with pneumocystis carinii pneumonia (PCP). To evaluate the clinical utility of this test we analyzed the admission LDH levels of patients hospitalized for the first time due to the secondary complications of AIDS. Among 76 patients without a prior history of PCP, 41 (54%) had PCP diagnosed during their hospitalization while 35 (46%) did not have PCP. Serum LDH was significantly higher among PCP patients than in patients without PCP (mean = 423 IU/L vs 234 IU/L). Receiver operating characteristic curve analysis demonstrated that at an optimal cutoff point of LDH greater than or equal to 240 IU/L, the test sensitivity and specificity were 0.78 and 0.74 respectively among all hospitalized patients. However, when only patients with dyspnea were considered, the optimal test sensitivity and specificity improved to 0.94 and 0.78 at a cutoff point of LDH greater than or equal to 220 IU/L. Comparing the areas under fitted ROC curves, serum LDH was a significantly better discriminator among patients with dyspnea than among those who were not short of breath. We conclude that while serum LDH is strongly associated with the presence of PCP among AIDS patients, it is a poor screening test for PCP when applied to all hospitalized AIDS patients with and without respiratory complaints. Serum LDH is no substitute for appropriate microbiological studies. However, with further evaluation, it may prove to be a useful test in guiding the clinical management of dyspneic patients in whom sputum or bronchial examinations are negative or not immediately available.

Pericarditis may be the most common cardiac manifestation in RA patients and the incidence in autopsy cases is more than 30%. Pericardial effusion shows low sugar and complement level and high level of LDH and gamma-globulin. The administration of corticosteroids has been successfully used in the treatment of rheumatoid pericarditis. The pulmonary involvement in RA include pleuritis, nodules and interstitial lung disease. Interstitial lung disease in RA patients appears to run a continuum from mild pneumonitis to severe pulmonary fibrosis and occasionally it include bronchiolitis obliterans organizing pneumonia (BOOP) which is sensitive to corticosteroid therapy. Although open lung biopsy is the definitive procedure for proving the diagnosis of interstitial lung disease, open lung is now being complemented or replaced by transbronchial lung biopsy and bronchoalveolar lavage (BAL). Corticosteroids will be effective to BOOP definitely and in general usual interstitial pneumonia (UIP) is resistant to treatment. In addition to the primary pulmonary manifestations of RA, anti-rheumatic drug reactions in the lung may be associated.

Increased synthesis of peptidoleukotrienes may occur in a variety of inflammatory diseases. To test this theory, hospitalized patients with a variety of diseases were studied and urine LTE4 quantitated as an index of total body peptidoleukotriene synthesis. 10 patients with ARDS, 7 of which had additional organ involvement, and 5 patients suffering from severe burn injuries were studied. Patients with uncomplicated ARDS excreted approximately 6-fold higher amounts of LTE4 in urine compared to healthy subjects. When ARDS was complicated by multiple organ failure (MOF), urine LTE4 levels were 2- to 150-fold higher than in healthy volunteers. Patients with severe burn injuries had peak urine LTE4 levels which were approximately 20-fold higher than in healthy volunteers. As additional controls, patients with cardiac arrhythmias (absence of inflammatory disease) and patients with uncomplicated pneumonia (localized inflammation) showed normal or mildly elevated urinary LTE4 levels. The urinary LTE4 levels in ARDS patients did not correlate with serum creatinine, bilirubin, or LDH levels, or with the WBC, nor did renal or liver failure by itself predict extremely elevated urinary LTE4 levels. In conclusion, patients with ARDS or ARDS/MOF and patients with severe injuries and sepsis syndrome excrete higher levels of urinary LTE4 than patients healthy volunteers or patients with limited inflammatory disease. In certain situations, urinary LTE4 levels may be useful as a marker of the degree of inflammation.

A 46-year-old man was admitted to Oita Medical College Hospital on October 16, 1987, because of cough and sputum. Chest X-ray and chest CT films showed diffuse reticulonodular shadow. The specimens obtained by transbronchial lung biopsy revealed cysts of pneumocystis carinii. Abnormal lymphocytes with lobulated nuclei were found 2-7% of peripheral leucocytes. The anti HTLV-I antibody was positive. According to these data, we diagnosed the patient as smoldering adult T cell leukemia with pneumocystis carinii pneumonia. The abnormal shadow on chest X-ray disappeared after SMX-TMP and pentamidine treatment. After about 1 year, he was again admitted for high fever. Chest X-ray showed infiltration with cavity in right upper lobe. Streptococcus pneumoniae was isolated from the sputum. The infiltration shadow on chest X-ray disappeared after antibiotics treatment. However, multiple nodular shadow appeared on the chest X-ray and ATL cell infiltration was found in the specimens of transbronchial lung biopsy. ATL cells in peripheral blood also increased and serum LDH and Calcium levels were markedly high. According to these data, we diagnosed the patient as having a ATL crisis. Although chemotherapy for ATL was started, the ATL, cell infiltration shadow on the chest X-ray enlarged, and bilateral diffuse patchy shadows was appeared on the chest X-ray. He died of respiratory failure on April 26, 1989. Cytomegalovirus pneumonia and ATL cell infiltration were revealed by necropsy.

Liver dysfunction in patients with measles infection is reported commonly in European and American literatures, but those in Japan are relatively rare. We observed the abnormal elevation of serum transaminase in 17 of 18 juvenile patients with measles from December 1989 to February 1990, however severe complications such as pneumonia or meningitis were not observed. A diagnosis of measles was made by typical clinical symptoms and the elevation of IgM antibody against measles (EIA method). Ninety four percent of the patients showed the elevation of serum transaminase, (GOT 118.6 +/- 96.2 IU/l, GPT 161.5 +/- 167.6 IU/l), and all patients recovered completely in 30.5 +/- 12.8 days after the onset. The abnormal evaluation of serum LDH was seen in 94% of the patients, (mean value was 872.2 +/- 216.2 IU/l). LDH4 mainly elevated in most cases, however, LDH5 elevated only in 4 cases. The intensity of liver dysfunction did not correlate to the severity of measles in the present cases. It is considered to be characteristic to the patients with measles that the serum level of LDH is markedly high as compared with that of transaminase.
