Ninety patients with serious infections, including 61 with septicaemia, pneumonia, peritonitis or meningitis, were treated with ceftazidime. Of these patients, 85.6% were clinically cured (73.3%) or improved (12.2%) by the antibiotic. In this study, 57.7% had infections due to Escherichia coli (24.7%), Klebsiella sp. (14.5%) and Pseudomonas sp. (18.5%). Two children with cystic fibrosis and Pseudomonas pneumonia and an adult with Legionella pneumonia responded well to ceftazidime treatment. Seventy patients had fever before treatment and most of them became apyrexial in less than 2 to 3 days. Ceftazidime was given either intramuscularly (42 patients) or intravenously (48 patients), in a dose of 1 g tds in 71 patients or 2 g tds in severe infections in 11 patients, or reduced to suit the renal function (7 patients) or in paediatric doses (2 children). Blood ceftazidime levels were measured in eight patients with normal renal function. The average level one hour post dosing was 45.2 mg/l and the average trough level was 8.1 mg/l. Six patients were suffering from variable degrees of renal insufficiency (serum creatinine 149 to 668 mmol/l). Their average blood level 1 h post-dosing was 68.8 mg/l. In a patient with meningitis, the CSF level was 2.4 mg/l 2 h after a 1 g dose. These levels are several times the ceftazidime MIC values for most clinical bacterial isolates. Ceftazidime is a valuable and safe alternative to aminoglycoside therapy.

Ceftazidime (CAZ) was evaluated for its safety and efficacy in 31 children. Of the 25 confirmed bacterial infections, 23 were cured by the CAZ therapy (efficacy rate, 92%). CAZ was assessed as effective in acute pharyngitis with vomiting (4), acute laryngitis (1), pneumonia (8), urinary tract infections (5), acute gastroenteritis (1), infection accompanying acute leukemia (septicemia suspected) (1), acute purulent meningitis (2) and abscess of the lateral cervical cyst (1). The main pathogens which responded to CAZ were H. influenzae, S. pyogenes, E. coli and P. aeruginosa. As adverse events, mild melena with prolonged prothrombin time (1) was found to be associated with the CAZ therapy. Half-life of the CAZ serum level was 0.97 +/- 0.10 hours, and urinary excretion was high. Penetration into the CSF in 2 cases of acute purulent meningitis was satisfactory. The data suggest that CAZ is a safe and effective injectable antibiotic when used in children with infections of CAZ-susceptible bacteria including P. aeruginosa.

Ceftazidime ( CAZ ), a new injectable cephem antibiotic, was used for treatment of infections in children, and the following results were obtained. After an intravenous injection of CAZ at a dose of 20 mg/kg, the mean blood levels in 2 patients were 41.5 micrograms/ml at 30 minutes, 18.1 micrograms/ml at 2 hours and 2.55 micrograms/ml at 6 hours, with the half-life (T 1/2) of 1.37 hours. In a 22-day-old baby with meningitis given CAZ intravenously at a dose of 43.5 mg/kg, the blood levels were 100 micrograms/ml at 30 minutes, 68 micrograms/ml at 2 hours and 25 micrograms/ml at 6 hours, with the half-life (T 1/2) of 2.96 hours. After intravenous administration of CAZ in doses ranging from 35.7 to 50 mg/kg, CSF concentrations ranged from N.D. to 6.3 micrograms/ml in 3 patients with purulent meningitis, although 19 micrograms/ml at 1 hour and 13 micrograms/ml at 2 hours in 1 patient after intravenous administration of 46.7 mg/kg. In patient with mumps meningitis, CSF concentrations were undetectable after intravenous administration of 35.7 mg/kg. Seventeen patients (each 1 patient with lymphadenitis, tonsillitis and septicemia, each 2 patients with pneumonia, bronchiectatic bronchitis, pyothorax and purulent meningitis, each 3 patients with pyelonephritis and enteritis) were treated with CAZ intravenously, at the daily doses of 178.2 mg/kg and 200 mg/kg in 4 divided doses in patients with meningitis and 44.1 to 103.4 mg/kg in 3 divided doses in patients with other infections (two of them were given by intravenous drip infusion for 30 minutes). The clinical responses were excellent or good in all the patients except for 1 case of Salmonella enteritis (poor) and 1 case of Campylobacter enteritis (poor). The efficacy rate was 88.2%. It was noteworthy that the clinical response was excellent in 1 case of septicemia with P. aeruginosa with leukemic stage of malignant lymphoma and in 2 cases of purulent meningitis. As side effects, fever, eruption, leukocytopenia, elevation in GOT and positive CRP considered to be allergic, were observed on day 16 of administration in 1 case of pyothorax. These symptoms disappeared by discontinuance of administration. In addition, there were elevation in GOT and GPT in 2 cases and elevation in GOT in 2 cases and elevation in GPT in 1 case; they were all mild or transient, and there was nothing to be worried about.(ABSTRACT TRUNCATED AT 400 WORDS)

Ceftazidime ( CAZ ), a newly-developed parenteral cephem antibiotic, was administered to 8 children; by one shot intravenous (i.v.) injection in the doses of 20 and 40 mg/kg each to 2 children, and by 30 minutes' i.v. drip infusion in the doses of 10 and 20 mg/kg each to 2 children, and the serum levels, urinary levels and recovery rates were determined. CAZ was also administered to 2 patients with purulent meningitis, one complicated with subdural abscess and the other with bacteremia, in the doses of 19.2 and 50.7 mg/kg, respectively, by one shot i.v. injection, and the CSF level of CAZ was determined. In addition, CAZ was administered to 2 children with acute bronchitis, 1 with chronic bronchitis, 37 with pneumonia, 3 with pleuropneumonia, 1 each for purulent meningitis, purulent meningitis accompanied with subdural abscess and purulent meningitis with bacteremia, 5 with urinary tract infections and 3 with purulent lymphadenitis (total 54 children), in the mean dose of 85.8 mg/kg/day mostly in 4 divided doses by one shot i.v. injection for 9 days on the average, and clinical effectiveness and bacteriological response were evaluated in these cases, and adverse events and abnormal laboratory findings were examined in the 66 cases which included 12 drop-out cases. 1. After the administration of CAZ to 4 children; 20 and 40 mg/kg each to 2 children, by one shot i.v. injection, the mean serum levels got to the peak of 115.8 and 199.5 mcg/ml, respectively, at 5 minutes. The results were good, showing dose response. The mean half-lives were 1.48 and 1.37 hours, respectively. After the administration of 10 and 20 mg/kg of CAZ each to 2 children by 30 minutes' i.v. drip infusion, the mean serum levels got to the peak of 58.5 and 80.0 mcg/ml, respectively, on completion of the administration, showing dose response. The mean half-lives were 1.06 hours in the former 2 cases, and 1.38 and 3.26 hours, respectively, in the latter 2 cases. The reason for the prolongation observed in 1 case was not clear. 2. In the above mentioned each 2 cases receiving one i.v. injection, the mean urinary levels got to the peak of 4,240 and 4,445 mcg/ml, respectively, at 0-2 hours after the administration , and the urinary recovery rates during the first 6 hours were high, 95.7% and 99.5%, respectively.(ABSTRACT TRUNCATED AT 400 WORDS)

A new semisynthetic 1-oxa-beta-lactam derivative, 6059-S, was evaluated for its safety and efficacy in children. Twenty-five patients were treated with 10 to 274 mg/kg per day of 6059-S by intravenous administrations. The diagnosis of the patients were acute pharyngitis (2), acute bronchitis (2), pneumonia (4), pertussis (4), acute enterocolitis (2), recurrent urinary tract infection (2), suspected septicemia (3), and acute purulent meningitis (1); and the remaining 5 patients were considered to have nonbacterial infections. The pathogens recovered were Streptococcus pneumoniae (1), Haemophilus influenzae (4), Haemophilus parainfluenzae (1), Enterobacter cloacae (1), Enterobacter aerogenes (1), Proteus morganii (1), Psuedomonas aeruginosa (2) and Salmonella typhimurium (1). All the patients of bacterial infections were cured after the 6059-S therapy. However, Pseudomonas aeruginosa and Salmonella typhimurium were not eradicated after the 6059-S therapy, and the rate of bacterial disappearance was 75%. Diarrhea (3), precordial pain (2, only in cases with high-dose therapy), transient elevation of GOT and GPT (2), and transient eosinophilia (2) were found to be associated with the 6059-S therapy. However, no severe adverse reactions were encountered. Half life of the serum 6059-S level was 1.34 +/- 0.16 hours. CSF concentrations in a case with Haemophilus influenzae meningitis ranged 4.0 to 9.7 mcg/ml after an intravenous injection of 34.3 to 75 mg/kg of 6059-S. From the present study, 6059-S appears to be a safe and effective antibiotic when used in children with susceptible bacterial infections. It remains to be further determined whether 6059-S is superior to ABPC in the treatment of Haemophilus influenzae meningitis.

Cefotetan (CTT), a new cephamycin antibiotic having a long serum half-life (2.93 +/- 0.78 hours), was evaluated for its safety and efficacy in children. Twenty-four patients were treated with a daily dose of 30 to 100 mg/kg of CTT by intravenous administrations mostly in 2 divided doses. The diagnoses of the effective patients were acute bronchitis (5), pneumonia (4), acute urinary tract infections (4), acute enterocolitis (2), presumed septicemia (1), and phlegmon (1); and the effectiveness was 77.3%. The pathogens recovered from these patients were S. pneumoniae (1), H. influenzae (3), S. marcescens (1), E. coli (2), and K. oxytoca (1). CTT was not effective in staphylococcal pneumonia and empyema (each 1 case), in Pseudomonas pneumonia (2), and in a case of brain abscess and mastoiditis of unknown etiology. Diarrhea (2), and transient elevations of the serum GOT, GPT, and LDH (1) were associated with the CTT therapy, but no severe adverse reaction was encountered. The CSF level of CTT seemed to be lower among several new cephalosporins. From the present study, CTT appears to be a safe and effective antibiotic when used in children with susceptible bacterial infections. A twice-a-day schedule was recommended from its long serum half-life.

Lipids, lipoproteins and lipid peroxidation in the blood serum, erythrocyte membranes and CSF were examined in 110 patients (aged 1 month to 3 years) with infectious neurotoxicosis developed in the presence of acute respiratory viral infections, pneumonia and intestinal infection. The results obtained showed a considerable fall in the level of total phospholipids and in their individual fractions in the blood serum and erythrocyte membranes; and their elevation in the CSF as well as increased lipid peroxidation in the blood serum and in the CSF. Among the questions discussed is a possible involvement of upset metabolism of lipids and their peroxides in the pathogenesis of infectious-toxic impairments of the nervous system in children of early age. The questions of their correction with lipostabilizing agents are also reviewed.

A child, who had undergone ventriculoperitoneal shunting, presented with repeated episodes of pneumonia and expectoration of CSF. Chest x-ray demonstrated the presence of the shunt catheter in the base of the left lung. In the present case the distal end of the catheter perforated the diaphragm, entering the thoracic cavity through the pleura and penetrating the pulmonary parenchyma. CSF then flowed freely into the alveoli and bronchi and became expectorated during repeated bouts of coughing associated with pneumonia. This respiratory complication disappeared after the removal of the catheter. We theorize that the penetration of the catheter into the thoracic cavity was secondary to its displacement from the iliac fossa to the left infradiaphragmatic space between the spleen and the diaphragm where the intra-abdominal pressure is lowest. The respiratory movements and the hypertension inside the abdomen created a constant friction of the catheter against the diaphragm which was finally perforated, permitting the passage of the peritoneal end of the shunting device into the thoracic cavity and secondary penetration of the lung.

Fifteen cases of Haemophilus influenzae (HI) meningitis in adults occurring of Cleveland during the last 11 years are presented. The majority of patients had factors predisposing to infection such as otitis, pneumonia, diabetes or alcoholism. In addition, 7 of the 15 patients developed meningitis at various intervals following head trauma and neurosurgery, and 3 patients required dural repairs for CSF rhinorrhea. The diagnosis of meningitis may be difficult to establish resulting in delay in appropriate therapy in some cases. Nuchal rigidity was absent frequently; CSF lymphocytosis can be seen initially. The CSF Gram stain may be negative or the pleomorphic nature of the organism on Gram-stain may make distinction from other gram-negative organisms difficult. The majority of patients had meningitis due to non-Type B HI in contrast to previous reports of this illness in children and adults. One of our patients had beta-lactamase producing HI isolated from CSF. We believe that chloramphenicol should be included in the initial empiric therapy for adults with meningitis and gram-negative coccobacillary rods on Gram-stain or negative CSF Gram-stains.

Three children suffered from mumps meningoencephalitis and pneumonia. The clinical course was uneventful. After 2 weeks antibiotic therapy for pneumonia a repeat lumbar puncture showed a massive increase of CSF protein levels. This phenomenon was transitory. It is explained by an obstruction in CSF pathway in the course of mumps meningoencephalitis.
