Cefixime is a new oral antibiotic with in vitro activity similar to that of parenteral third generation cephalosporins. It exhibits good in vitro activity against most pathogens causing urinary tract infections. The effectiveness and safety of cefixime were evaluated in a multicentre study involving 68 patients (45 with acute pyelonephritis, 15 with lower urinary tract infections and 8 with infections of undetermined location); 55 of these patients were assessable in terms of effectiveness. Clinical cure was achieved in 50 cases. The causative agent was always eradicated. During the 3 to 8 weeks' follow-up period, relapses occurred in 5 patients with pyelonephritis. Adverse effects were reported by 2 patients. Biological manifestations (thrombocytosis, elevated ASAT and ALAT) were noted in 5 cases. Cefixime is a safe and effective antibiotic for the treatment of urinary tract infections.

The pharmacokinetics, efficacy and safety of sulbactam/ampicillin (SBT/ABPC) were evaluated in 21 children with a variety of infections. The results obtained are summarized as follows. 1. Pharmacokinetics in 4 children, each receiving a single dose of 60 mg/kg, were evaluated. The average half-life of SBT was 1.03 hours and that of ABPC was 0.83 hour. 2. In vitro antimicrobiol activity (MIC) of SBT/ABPC in which SBT and ABPC are combined at a ratio of 1:2 was stronger than ABPC alone and was quite effective against Staphylococcus aureus and Haemophilus influenzae, but activity against Escherichia coli was relatively low. Antimicrobial activity of SBT/ABPC against S. aureus was almost equal to those of piperacillin (PIPC), cefazolin (CEZ) and cefmetazole (CMZ), but against H. influenzae was stronger than those of CEZ and CMZ. Activity against E. coli was lower than those of PIPC, CEZ and CMZ. 3. A total of 21 patients including 3 with pharyngitis, 10 with bronchitis, 5 with pneumonia, 1 each with acute enteritis, pyelonephritis and suspected sepsis were treated with SBT/ABPC. The clinical efficacy rate for these patients was 95.2% (20/21). The bacteriological eradication rate was 80% (8/10). 4. There were 4 instances of side effects, 1 case each of eruption, diarrhea, thrombocytosis and eosinophilia, but all symptoms were transient.

Ceftriaxone has a very long serum half-life and enhanced in vitro activity against common pediatric pathogens. Therefore we evaluated the efficacy and safety of once daily ceftriaxone therapy in 57 children with serious infections including: meningitis (26 patients); ventriculitis (3); pyelonephritis (7); osteomyelitis (6); abscess (4); septic arthritis (3); sepsis (2); and miscellaneous infections (6). The most common isolates were Haemophilus influenzae (23), Escherichia coli (9) and Staphylococcus aureus (8). Ceftriaxone was given intravenously or intramuscularly in a dose of 50 mg/kg for non-central nervous system (CNS) infections. Patients with CNS infections received an initial dose of 100 mg/kg followed by 80 mg/kg 12 hours later and once daily thereafter. In a limited number of patients no major differences in serum ceftriaxone concentrations were found after intravenous or intramuscular injection. Of 57 patients with pathogens isolated 55 were completely cured; in one patient with Klebsiella pneumoniae ventriculitis, intraventricular gentamicin was briefly added to the regimen. Another patient with an anaerobic liver abscess recovered after metronidazole was administered. In three patients a delayed response to ceftriaxone was noted. One patient with previous recurrent infections had a second episode of H. influenzae meningitis 22 days after cessation of therapy. Clinical side effects were noted in 10 of 71 patients (including 14 treated patients who had negative cultures). Seven patients had diarrhea, one each had fever or rash and one had fever, rash and arthralgia. Laboratory side effects in 16 of 71 patients included eosinophilia (7), thrombocytosis (7), elevated liver enzymes (4) and leukopenia and neutropenia (2).(ABSTRACT TRUNCATED AT 250 WORDS)

Fifty-nine children were enrolled in an open trial of aztreonam, a monocyclic beta-lactam, therapy for serious gram-negative infections. Thirty-six infections were microbiologically evaluable and received five or more days of therapy. Patients' ages ranged from 3 days to 12 years, and diagnoses included pyelonephritis or cystitis (20), deep soft tissue or joint infection (seven), septicemia (four), pneumonia (three), peritonitis, and epiglottitis. Causative bacteria included Escherichia coli and other Enterobacteriaceae, Pseudomonas aeruginosa, and Haemophilus influenzae. The standard regimen was 30 mg/kg every six or eight hours intravenously. All isolates were aztreonam-susceptible and were eradicated during therapy. Two patients had microbiologic relapses: a patient with Salmonella choleraesuis meningitis who was initially treated for only ten days and a patient with E coli pyelonephritis. Clinical cure was achieved in 31 of 36 children. Pharmacokinetic studies performed in six children demonstrated no difference in serum concentrations or pharmacokinetic variables between day 1 and day 7 of therapy. Although several patients had transient eosinophilia (eight), elevated levels of aminotransferase (seven), or thrombocytosis (ten), no clinically significant adverse effects were noted. In this initial, uncontrolled study, aztreonam was effective and safe in the treatment of a variety of serious gram-negative infections in children.

Often patients with fevers of unknown origin (FUOs) present with loss of appetite, weight loss, and night sweats, without localizing signs. Some are found to have a renal mass during diagnostic evaluation. In patients with FUOs and a renal mass, the differential diagnosis includes renal tuberculosis, renal cell carcinoma (hypernephroma), renal malakoplakia, and xanthogranulomatous pyelonephritis. A 68-year-old woman presented with an FUO during her diagnostic workup. She manifested an irregularly enlarged kidney on abdominal computed tomography (CT) scan, as well as a highly elevated erythrocyte sedimentation rate of more than 100 mm/hour, an elevated serum ferritin level, and chronic thrombocytosis, which favored a diagnosis of renal cell carcinoma. Renal malakoplakia and renal tuberculosis comprised further differential diagnostic considerations. Microscopic hematuria may be present with any of the disorders in the differential diagnosis, but was absent in this case. An abdominal CT scan was suggestive of xanthogranulomatous pyelonephritis. Because of concerns regarding renal cell carcinoma, the patient received a nephrectomy. The pathologic diagnosis was of xanthogranulomatous pyelonephritis, without renal cell carcinoma.
