MICs of BRL 25000, a combination of a newly developed beta-lactamase inhibitor CVA and AMPC in the ratio of 1 to 2, were determined against a number of bacterial strains and compared with those of AMPC, CVA, CEX and CCL. The 98 bacterial strains tested included 2-S. aureus, 23-H. influenzae, 25-E. coli, 22-K. pneumoniae and 26-P. mirabilis. In pharmacokinetic studies, BRL 25000 medium granules were administered to groups of 3 male subjects, aged between 7 years 8 months and 9 years 5 months, at doses of 10, 15 and 20 mg/kg, 2 hours after a meal. The resultant serum and urine concentrations and drug recoveries were measured. Furthermore, BRL 25000 was administered to a total 43 patients (2-pharyngitis, 8-tonsillitis, 3-bronchitis, 2-pneumonia and 28-urinary tract infection) whom clinically evaluable. An average daily dosage of 45.3 mg/kg was given, in 3 or 4 divided doses, for a period of 8 days on average. Clinical and bacteriological effects as well as side effects were studied. In the microbiological studies on 98 clinical strains, including beta-lactamase negative bacteria, BRL 25000 showed MICs against the Gram-positive cocci (2-S. aureus) superior to the other 4 drugs at inoculum sizes of 10(8) and 10(6) cells/ml. For the Gram-negative bacilli, against H. influenzae at inoculum sizes of 10(8) and 10(6) cells/ml, BRL 25000 was inferior in the small MIC range but superior in the large MIC range to AMPC, and was superior to the other 3 drugs. Against E. coli at an inoculum of 10(8) cells/ml, BRL 25000 showed antibacterial activity next to AMPC and CCL whilst at an inoculum of 10(6) cells/ml, it was inferior in the small MIC range but superior in the large MIC range to AMPC and CEX and was inferior to CCL but superior to CVA. Against K. pneumoniae at an inoculum of 10(8) cells/ml, BRL 25000 was equal to AMPC, CVA and CEX but inferior to CCL, whilst at an inoculum of 10(6) cells/ml, it was inferior to CCL but superior to the other 3 drugs. Against P. mirabilis at inoculum sizes of 10(8) and 10(6) cells/ml, BRL 25000 was inferior in the small MIC range but equal or superior in the large MIC range to AMPC, and was superior to CVA and CEX.(ABSTRACT TRUNCATED AT 400 WORDS)

Despite uniform susceptibility of group A streptococci to penicillin, failure to eradicate group A streptococci is not uncommon in patients receiving penicillin for treatment of pharyngitis. We explored the possibility that penicillin tolerance could explain this phenomenon. We examined 48 group A streptococcal isolates from 48 patients successfully treated with penicillin (streptococci eradicated) and 92 isolates from 37 patients (one to four isolates per patient) who failed to respond to penicillin therapy (streptococci not eradicated). Penicillin tolerance was recognized by the gradient-replicate plate method and by time-kill experiments with penicillin concentrations of 16 times the minimal inhibiting concentrations. Tolerance was identified in 25% (23 of 92) of the isolates from the treatment failure group, in contrast to none of the strains from the treatment success group. Characterization of the strains by M and T typing revealed no predominant type(s) among the tolerant strains. These findings suggest that penicillin tolerance may be responsible for some instances of failure of penicillin to eradicate group A streptococci from the upper respiratory tract of individuals with streptococcal tonsillitis or pharyngitis.

Recently many refugees from Sri Lanka have arrived in Europe. The purpose of the present investigation was to analyze the subjective complaints and diagnoses in these refugees. One hundred refugees (97 males, 3 females, age 19 to 42 years) were investigated. The most common reasons for consulting a general internist were cough (23%), general pain in soft tissue and joints (21%), disorders of the gastrointestinal tract (19%) and ear or throat complaints (15%). In 43% of the patients no diagnosis could be established. 58 patients were investigated for parasites in stool: 57% of these patients had hookworms, 12% non-pathogenic protozoon, 9% Entamoeba histolytica cysts, and 2% Giardia lamblia. In 12% of the patients the diagnosis was tonsillitis or pharyngitis, in 7% bronchitis, pneumonia or asthma and in 5% arterial hypertension. Various other diagnoses were established in 48 patients. With the exception of the high frequency of intestinal parasites, complaints and diagnoses in these refugees were the same as in a comparable European population.

Infectious pneumonias are inflammations of the lung that can be localized in the alveoli or interstitial tissue or both. The pathogenic agent is usually airborne; more rarely it is hematogenous. Important distinctions are between bacterial and nonbacterial forms, between diseases acquired outside and inside hospitals, and between patients who are basically healthy and those with a previous illness. Pneumococci continue to be the dominant pathogens outside hospitals. In hospitals, gram-negative, anaerobic, and fungal pathogens are more often found. Usually, purulent chronic bronchitis or an acute exacerbation of chronic bronchitis is based on a prior viral infection or an impairment of bacterial clearance mechanisms of the respiratory tract. The dominant pathogens are Haemophilus influenzae and pneumococci. Worldwide, viral infections of the upper respiratory tract have great epidemiological significance. With 12 different groups of viruses and more than 150 serotypes, there can be many causes of symptoms of rhinitis, tonsillitis, pharyngitis, laryngitis, and tracheitis as well as bronchitis.

Pharmacokinetics of ceftizoxime (CZX), a new cephalosporin antibiotic, was investigated in 9 children with normal renal and hepatic function. In addition, the clinical effect of CZX was evaluated in 26 pediatric patients with various infections. In 4 of the 9 children with normal renal and hepatic function, intravenous bolus injection of CZX in a dose of 20 mg/kg yielded a mean peak serum level of 36.5 micrograms/ml at 1/2 hour after infusion, and mean serum levels of 12.5 micrograms/ml at 2 hours and 6.0 micrograms/ml at 4 hours after infusion. The biological half-lives of CZX were estimated to be 1.25--2.55 hours. In another child, serum levels of CZX at 1/2, 2 and 4 hours after intravenous bolus injection in a dose of 10 mg/kg were 19.60, 5.96 and 2.06 micrograms/ml, respectively. The clear difference in dose response between 20 mg/kg and 10 mg/kg reflected the doubled dose levels. In the remaining 4 children, drip infusion of CZX in a dose of 20 mg/kg (1 child 17 mg/kg) over 0.5--1.5 hours yielded peak serum levels at the end of infusion. The biological half-lives of CZX were estimated to be 0.95--1.50 hours. About 80% of CZX was excreted in the urine within 6 hours after infusion in the 4 children tested. Twenty-six pediatric patients with various infections were treated with CZX intravenous doses of 20 mg/kg to 118 mg/kg b.i.d.--q.i.d. for 3--14 days. Of the 12 patients with acute bronchitis and pneumonia, 5 showed excellent response, 6 good and 1 fair response. Of the 5 patients with urinary tract infection, 4 showed excellent response and 1 good response. One patient each with colitis, tonsillitis and facial cellulitis, pharyngitis showed excellent response and 1 patient each with purulent thyroiditis and gluteal abscess showed good response. The single patients with sepsis showed excellent response. One patient each with pyothorax, purulent arthritis and cerebral abscess showed poor response. Overall effectiveness rate was 84.6%. although 22 of all 26 patients treated had serious underlying diseases such as APL, AML. A mild increase in GOT and GPT was observed in 1 patient during treatment with CZX, and the values returned to normal after discontinuation of the drug. These results suggest that ceftizoxime is 1 of the most important antibiotics for treating a wide range of infections in children as well as in adults.

T-1982 (cefbuperazone), a new injectable cephamycin antibiotic, was studied for its antibacterial activity, concentration in serum and urine, penetration into cerebrospinal fluid (CSF) as well as clinical application. The following results were obtained. 1. Antibacterial activity: The susceptibilities of clinically isolated K. pneumoniae, E. coli and E. cloacae to T-1982 were superior to those of CEZ CMZ, and ABPC. T-1982 seemed to be useful for various infections due to Gram-negative rods. 2. Concentration in serum and urine: Subjects were 10 children with congenital heart failure but no abnormal renal and liver functions. T-1982 was given intravenously to 3 groups at 200 mg/kg by one shot (4 cases), 20 mg/kg by 1 hour drip infusion (3 cases) and 10 mg/kg by 1 hour drip infusion (3 cases). The half-lives were 60, 78 and 85 minutes, respectively. 3. Penetration into cerebrospinal fluid: Three children with malignant tumor were injected 20 mg/kg intravenously. A small amount of T-1982 was penetrated into CSF. 4. Clinical efficacy: T-1982 was administered daily 40-116 mg/kg t.i.d. or q.i.d. for 2-14 days to 17 children comprising 1 bronchopneumonia, 1 bronchitis, 4 tonsillitis, 1 lymphadenitis, 1 sepsis, 1 pharyngitis, 1 impetigo, 1 acute sinusitis and 6 pyelonephritis. Clinical efficacy was excellent in 10, good in 2, fair and poor in 3, and the efficacy rate was 70.6%. Bacteriological effect was as follows; eradicated in 9 cases and unknown in 8 cases. As side effect, GOT and GPT elevations unrelated to the drug were observed in 2 cases. Other abnormal findings were not found. T-1982 seems to be safe antibiotic in the field of pediatrics.

Children, aged 6 months to 5 years, were pair-matched with respect to age and history of otitis media acuta. The 405 children received either a subcutaneous injection of Pneumovax (a 14-valent pneumococcal vaccine) or of saline, in a double-blind fashion. The follow-up period for each child was 1 1/2 years. In children younger than 2 years at vaccination no difference was recorded between vaccinees and controls concerning the number of consultations due to otitis media acuta or to other upper respiratory tract infections. In children older than 2 years at vaccination a reduction in the overall frequency of visits due to upper respiratory tract infections was observed after vaccination. The incidence of otitis media acuta was reduced during the first postvaccinal year while visits due to tonsillitis and pharyngitis were reduced during the whole follow-up period in vaccinees as compared to controls.

A comparative well-controlled study was performed to evaluate the efficacy and tolerability of ampicillin rectal suppository (KS-R1) compared with those of oral form of ampicillin (ABPC) against acute respiratory tract infections in pediatric field. KS-R1 at the dose of 125 mg X 4/day of ABPC in potency, or the oral form at the same dosage, was given to 166 cases of patients with acute respiratory tract infection due to Streptococcus pyogenes, Streptococcus pneumoniae or Haemophilus influenzae for 7 days, as a rule. The clinical efficacy rates evaluated in 151 cases (KS-R1 group in 77 cases, oral group in 74 cases) on standard criteria of committee members were 88.3% for the KS-R1 group and 86.5% for the oral group, respectively. There was no significant difference between 2 groups. Evaluation by stratification according to the diagnosis showed that the efficacy rates for the KS-R1 group and for the oral group were 87.5% and 85.0% against pharyngitis, 90.5% and 90.0% against tonsillitis and 84.2% and 78.6% against bronchitis, respectively. None of them showed significant difference between 2 groups. The bacteriological effect was evaluated in 55 cases (KS-R1 group in 33 cases, oral group in 22 cases), and disappearance rate was 93.9% for the KS-R1 group and 95.5% for the oral group, showing no significant difference. Side effect including subjective and objective symptoms were strictly evaluated in 163 cases (KS-R1 group in 83 cases, oral group in 80 cases), but the incidence rate which was 22.9% for the KS-R1 group and 23.8% for the oral group showed no significant difference. The above results indicate that against acute respiratory tract infections in pediatric field, KS-R1 possesses clinical efficacy and safety similar to the oral form of ABPC, and that it is a useful suppository.

Clinical trials of KS-R1 have been carried out on 28 infections in children, including 8 pharyngitis, 11 tonsillitis, a pharyngolaryngobronchitis, 3 lymphadenitis and 5 urinary tract infections. The following results were obtained. KS-R1 30-50 mg/kg/day, was clinically effective in 27 out of 28 infections. Bacteriologically, the following routine clinical isolates were identified; Enterococci in 1 case, S. viridans 1 case, S. pneumoniae 1 case, S. pyogenes 2 cases, H. parainfluenzae 1 case, E. coli 5 cases and S. aureus + H. influenzae 1 case. Every isolated organism showed +++ sensitivity to the ABPC sensitivity disc in vitro without only 1 case of E. coli. The organisms were eradicated in 11 patients after the administration of KS-R1. Adverse effects did not occur in any patient without case 25, who complained of pollakiuria.

Cephalexin, a semisynthetic cephalosporin antibiotic, has wide clinical application in respiratory infections of children and adults. In pharyngitis and tonsillitis due to beta-haemolytic streptococci, it is comparable to penicillin, cyclocillin, and cephaloglycin, as measured by clinical response, bacteriological cure rate, and incidence of relapse and reinfection. In otitis media, it is effective at dosages of 50-100 mg/kg/day except in those infections caused by Haemophilus influenzae, in which there is failure in 50% of the cases. In other infections of the upper respiratory tract, it appears to be effective except, again, in those caused by H. influenzae. Dosages of 1-2 g/day have been used in adults and 20-100 mg/kg/day in children. Adverse effects, mostly gastrointestinal upsets, rash, and urticaria, have been relatively infrequent and have not required discontinuance of the drug.
