Fundamental and clinical studies of cefotetan (CTT) were made in pediatric field and the following results were obtained. Antimicrobial activity MIC80 values of CTT against clinically isolated S. aureus (32 strains), E. coli (33 strains) and K. pneumoniae (33 strains) were 25, 0.1 and 0.1 microgram/ml respectively. Antimicrobial activities of CTT against E. coli and K. pneumoniae were superior to those of CMZ, though the activity against S. aureus was inferior to that of CMZ. Pharmacokinetics When 20 mg/kg of CTT was administered to 3 children, who were 3 to 8 years of age, by a intravenous bolus injection, the mean serum concentrations of the drug after 1/2, 1, 2, 4, 6 and 8 hours were 110.7 +/- 9.2, 81.7 +/- 10.1, 50.0 +/- 7.5, 25.3 +/- 4.6, 14.9 +/- 5.5 and 7.7 +/- 2.8 micrograms/ml respectively, and the mean half-life (beta) was 2.01 +/- 0.32 hours. The mean concentrations of the drug in urine after 0-2, 2-4, 4-6 and 6-8 hours were 1,377 +/- 787, 1,045 +/- 689, 1,067 +/- 680 and 358 +/- 80 micrograms/ml respectively, and the mean recovery rate by 8 hours was 67.3 +/- 16.2%. Clinical study CTT was administered to 42 children of 2 monthes to 14 years of age, and clinical response, bacteriological effect and adverse reaction of the drug were studied. Clinical effects were evaluated in 8 cases of acute purulent tonsillitis, each 1 case of acute otitis media and acute bronchitis, 16 cases of acute bronchopneumonia or acute lobar pneumonia, 9 cases of acute pyelonephritis and 1 case of erysipelas, the results were excellent in 30 cases, good in 3, fair in 2 and poor in 1, and thus 91.7% of efficacy rate was obtained. Out of suspected causative organisms including 12 strains of H. influenzae, 1 strain of H. parainfluenzae, 7 strains of E. coli, 2 strains of S. pyogenes, 2 strains of S. pneumoniae and each 1 strain of S. epidermidis and S. faecalis, all the strains except each 1 strain of H. influenzae and S. faecalis disappeared after the treatment. Thus 92.3% of eradication rate was obtained. No side effects were recognized. Though abnormal laboratory findings were observed in 3 cases (7.1%), including elevation of GOT and GPT in 2 cases and eosinophilia in 1 case, those findings came to be normal after the treatment.

A 66-year-old man with erysipelas was admitted with complaints of oliguria and massive proteinuria/hematuria. He was diagnosed as having acute poststreptococcal glomerulonephritis(APSGN) due to erysipelas infected by group A streptococcus pyogenes. On admission, his white cell count increased to 31,000, and CRP was 27.3 mg/dl. Serum urea nitrogen and creatinine were increased to 90.1 mg/dl and 4.5 mg/dl, respectively. He had diabetes mellitus(HbA1c 7.9%) and liver dysfunction(total bilirubin 3.5 mg/dl, AST 76 IU, ALT 41 IU) caused by alcoholic liver cirrhosis. Hypocomplementemia was found in addition to ASO 216 U/ml and ASK 10,240 x. After antibiotics treatment was initiated, inflammation of the erysipelas began to improve. Disseminated intravascular coagulation syndrome, probably due to sepsis, occurred on the 5th hospital day. He died of gastrointestinal bleeding on the 18th hospital day. Renal autopsy revealed 37% formation of fibrocellular crescents, and marked mesangiolysis was noted by light microscopy. Granular deposition of C3 and IgG was seen along the capillary walls on immunofluorescence study. Intramembranous deposits were scattered on electron microscopy. This case illustrates a fulminant type of APSGN, which was in part attributed to the presence of diabetes and alcoholic liver cirrhosis. Histological findings of crescent formation and marked mesangiolysis may account for the fulminant clinical course.

Drug-induced liver injury (DILI) to flucloxacillin is rare and is classified as idiosyncratic, as it is dependent on individual susceptibility, unpredictable, and dose-independent. The authors present the case of a 74 - year - old man with a history of monoclonal gammopathy under investigation and alcoholic habits of 24 g/day, with asthenia, anorexia, nausea, abdominal discomfort, and fever with three days of evolution. He was treated with two courses of antibiotic therapy with flucloxacillin to erysipelas previously (3 months and 2 weeks before admission). Lab tests showed serum AST levels of 349 U/L, ALT 646 U/L, alkaline phosphatase 302 U/L, GGT 652 U/L, total bilirubin 3.3 mg/dL and direct bilirubin 2.72 mg/dL. Infectious, autoimmune, and metabolic causes were ruled out. Magnetic resonance cholangiopancreatography showed normal results. Liver biopsy showed mild multifocal (predominantly microvesicular) steatosis; marked changes in the centrilobular areas (sinusoidal dilatation, marked congestion, hemorrhage, and multifocal hepatocyte collapse); expansion of the portal areas with the formation of bridges; proliferated bile ducts and inflammatory infiltrate of variable density, predominantly mononuclear type. The HLA-B*5701 screening test was positive. Hepatic biochemical tests remain abnormal with a significative increase in total bilirubin, which reached levels of 24.1 mg/dL, with the development of jaundice, pruritus, and choluria. DILI was assumed, and the patient was treated with ursodeoxycholic acid. There was favorable evolution, without evidence of blood coagulation dysfunction or encephalopathy. The analytic normalization was, however, slow, with evolution to chronicity. The authors present this case to remind the possibility of moderate/severe drug-induced liver injury to flucloxacillin, an antibiotic commonly used in clinical practice and association with the HLA-B * 5701 allele reported in the literature.
