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)

Laboratory and clinical studies of cefoperazone (CPZ), a new semisynthetic cephalosporin, were investigated and following results were obtained. (1) Blood level: CPZ was given intravenous dose of 25 mg/kg and 50 mg/kg to each 3 children. In the former, the blood level of 15 minutes after injection was 194.2 mcg/ml on average and the half life was 106.2 minutes. In the latter, the blood level was 320.0 mcg/ml on average and half life was 102.2 minutes. (2) Urinary concentration: In the cases of the dose of 25 mg/kg, 35.9% of CPZ was recovered on average from the urine within 6 hours after injection, and the urinary concentration reached to 2,148.6 mcg/ml (0 approximately 2 hours). And in the cases of the dose of 50 mcg/kg, the recovery rate in urine was 43.6%, and the urinary concentration was 3,008.3 mcg/ml. (3) Cerebrospinal fluid level: CSF level was determined in a patient with bacterial meningitis by S. pneumoniae. Ninety mg/kg of CPZ were given intravenous injection. After 60 minutes CSF level was 3.35 mcg/ml, and after 80 minutes the blood level was 192.0 mcg/ml. (4) Bacteriological evaluation: Against 164 strains isolated clinical specimens, the bacteriological evaluation on CPZ was performed in comparison with cefotaxime (CTX), cefazolin (CEZ) and piperacillin (PIPC) by inoculum size of 10(8) cells/ml. CPZ showed antibacterial activity against Gram-negative bacteria almost similar to CTX and PIPC. (5) CLINICAL RESULTS: CPZ was given 48.3 approximately 360 mg/kg/day (average 146.1 mg/kg/day) by intravenous route to 46 patients with various infection. The overall efficacy rate was 80.4%. The rate of bacteriological effectiveness was 78.9% in 19 cases. (6) Side effects: As side effects, diarrhea, fever, rash, urticaria, leukopenia, eosinophilia, elevation of GOT, GPT, and LDH were observed, but not seriously.

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.

Experimental and clinical studies in the pediatric field on 6059-S, a newly synthesized broad spectrum parenteral antibiotics, were carried out, and the following results were obtained. Antibacterial activities of 6059-S against S. pyogenes, S. aureus, E. coli and P. aeruginosa, recently isolated from patients, 50 strains respectively was compared with that of cefazolin (CEZ), cefmetazole (CMZ), ceftizoxime (CZX), cefotiam (CTM) and ticarcillin (TIPC). 6059-S was less active than the other compound against S. aureus and S. pyogenes, but was about 1-5 times more active than other CEZ, CTM, CMZ and CZX against E. coli, and 6059-S had a activity against P. aeruginosa. It was equal or slightly more activity than that of TIPC. Serum concentrations were measured in 14 infants (3 y 3m-12 y) by one shot or intravenous drip infusion with 10 mg/kg or 20 mg/kg. By one shot intravenous infusion, the peak of serum concentrations of 6059-S with 10 mg/kg and 20 mg/kg were 40.4-44.2 mcg/ml, 79.1-90.8 mcg/ml at 30 minutes after administration respectively, and that's half life were 1.5, 1.4 hours. By intravenous drip infusion, the peak of serum concentration was 89.9 mcg/ml at the end of administration, 13.7 mcg/ml at 5 hours after administration, and half life was 1.5 hours. The urinary recovery rate of 6059-S were 97.4, 67.4% during 6 hours in 2 cases. The cerebrospinal fluid concentration of 6059-S were 2.4-3.6 mcg/ml at 90 minutes after intravenous infusion administration, and the CSF/serum ratio were about 7-8%. Clinical studies of 6059-S was performed in total of 27 cases (25 patients); 8 cases of urinary tract infection, 15 cases of respiratory tract infection, 1 case of staphylococcal scalded skin syndrome, 1 case of peritonitis, 2 cases of purulent meningitis, with the dose of 6059-S 150 mg/kg/day in purulent meningitis, 40-80 mg/kg/day in other disease. That's efficacy rate was 85.2%. Side effect observed in this therapy were 2 cases (exanthema 1, diarrhea 1), and 2 cases of rise of GOT, GPT.

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.

Five patients with HSE were treated with adenine arabinoside and one additional patient with cytosine arabinoside. The diagnosis of HSE was confirmed in retrospect by the rising CF titers and the Enzyme-Linked Immunosorbent Assay (ELISA) levels in CSF (Table 2). Brain biopsy was not performed. The treatment was started promptly when HSE was strongly suspected by symptoms and signs, EEG, CT and CSF findings before the specific laboratory data were available. The clinical and laboratory data on the 6 patients were shown in Table 1. All the 5 patients of HSE treated with adenine arabinoside survived: 3 returned to normal daily life, including one having no neurological deficits, and the other 2 had mild to moderate memory disturbances. Improvement of CT abnormalities indicated a good prognosis. Age or sex did not have influence on the prognosis. The patient treated with cytosine arabinoside died of complications after being in a state of apallic syndrome for 1 year and 8 months. On the basis of the analysis of our patients, one of the crucial factors in the treatment of HSE seems to be the earliest possible use of adenine arabinoside: in our patients on the 2nd up to 9th day of onset, although there was no correlation between the day the medication was started and the morbidity. The other important factor includes the management of acute stage of HSE: the treatment of cerebral edema and generalized convulsions. The major side effects of adenine arabinoside included diarrhea (one case), elevation of GOT, GPT or LDH (one case) which all improved after the treatment. Adenine arabinoside could be an effective drug for HSE reducing the mortality and morbidity with few side effects.

The concentrations of many components of the cerebrospinal fluid are much lower than in serum. Values for sodium, potassium, calcium and magnesium are similar to those in other primates. Activities of alkaline phosphatase (18.7 U/1), creatine phosphokinase (9.9 U/1), glutamine oxaloacetate transaminase (13.7 U/1), glutamine pyruvate transaminase (9.2 U/1), gamma-glutamyl transpeptidase (3.1 U/1), alpha-hydroxybutyrate dehydrogenase (33.0 U/1, lactate dehydrogenase (47.2 U/1) and sorbitol dehydrogenase (3.9 U/1), and levels of zinc (1.0 mu g/dl), copper (2.6 mu g/dl), iron (35.9 mu g/dl) and triglycerides (33.2 mu g/dl) have not previously been reported for this species. Values for free amino acids, total protein, creatinine and urea nitrogen are compared with those of other primates. The use of gradient pore polyacrylamide gel electrophoresis for analysing proteins of CSF is described.

The CPK, aldolase, GOT, GPT, and LDH concentrations in the serum and lumbar CSF of 80 patients with neuromuscular diseases and 20 controls were measured. The value obtained in serum was essentially in agreement with the data in the literature. This is the first publications reporting on regular CSF enzyme examinations in different neuromuscular disorders, particularly the results obtained in neurogenic muscular atrophies, which have certain characteristic features. The LDH activity in CSF was decreased in peroneal muscular atrophy, the GPT concentration in CSF was elevated in spinal muscular atrophy, and the mean activity of CSF aldolase was increased in amyotrophic lateral sclerosis. The simultaneous determination of enzymes in serum and CSF can provide valuable information in the research of certain details of pathomechanisms and thus lead to further improvement of diagnosis.

Glutamic oxalacetic and glutamic pyruvic transaminase levels in CSF and blood were estimated in 25 normal individuals and 50 patients with varying grades of head injury. CSF GOT, and to a lesser extent GPT, showed significant elevation proportionate to the degree of brain injury. Serum GOT was raised in more severe injuries. CSF GOT and GPT levels showed a significant correlation with the prognosis of the case.

Interferon therapy in cirrhotic patients with hepatitis C virus infection is not efficient. In an attempt to improve the response rate, a pilot study using recombinant human granulocyte colony-stimulating factor (rhG-CSF) alone, and in combination with recombinant interferon-alpha (rIFN), was carried out. Fifteen cirrhotic patients with hepatitis C virus infection were randomly allocated into 3 groups to receive treatment: 0.5, 1, or 1.5 micrograms/kg of rhG-CSF daily for 4 weeks, followed by a 4 week resting period, and by the same dose of rhG-CSF daily, plus 6 MU of rIFN 3 times weekly for 4 weeks. They then continued to receive 6 MU of rIFN alone for 4 weeks, followed by 3 MU of rIFN for 16 weeks. After the 4 weeks of treatment with rhG-CSF alone, no changes in alanine aminotransferase (ALT) levels were observed. No changes occurred during the resting period. Three of 10 patients who ended the rhG-CSF plus rIFN treatment period had normal ALT values. During the treatment with rIFN alone, two responders suffered a relapse. The other responder had normal ALT until the first month of follow-up. In summary, the combination of rhG-CSF and rIFN seems promising for the treatment of patients with chronic hepatitis C and liver cirrhosis.
