Cefixime was compared with amoxicillin for treatment of acute otitis media in a randomized trial. Results of tympanocentesis on day 3 to 5 of therapy were used as the major outcome. Total daily doses were 8 mg/kg of cefixime and 40 mg/kg of amoxicillin. One hundred twenty-six patients were randomly assigned to receive treatment; 64 cultures grew pathogens. Pathogens were eradicated from the middle ear after 3 to 5 days of therapy in 27 (79.4%) of 34 children given amoxicillin and 26 (86.7%) of 30 children given cefixime (p = 0.47). When Streptococcus pneumoniae cases were analyzed, bacteriologic cure occurred in 14 (93.3%) of 15 children given amoxicillin and 12 (75%) of 16 given cefixime (p = 0.333). When cases of Haemophilus influenzae infection were analyzed, significantly more cures occurred with cefixime (10/10, 100%) than amoxicillin (8/13, 62%) (p = 0.046). Pathogens associated with failure of amoxicillin therapy were H. influenzae (five cases, two beta-lactamase-positive), S. pneumoniae (one case), and Moraxella catarrhalis (one case, beta-lactamase-positive). The four failures with cefixime therapy were all in patients infected with S. pneumoniae. Rates of rash, diarrhea, and vomiting were the same in both groups and did not necessitate stopping therapy. We conclude the following: (1) Cefixime and amoxicillin were equivalent in overall clinical and bacteriologic efficacy for otitis media. (2) Cefixime was more efficacious than amoxicillin in treating H. influenzae otitis media and should be preferred when H. influenzae is the suspected etiologic agent. (3) Side effects of both drugs were mild and equivalent.

Imipenem/cilastatin sodium (IPM/CS) was administered to 55 patients with respiratory tract infections (RTI). A clinical evaluation of IPM/CS was carried out in 51 patients, 28 with pneumonia, 4 with pulmonary abscess, 1 with pyothorax, 6 with bronchitis, 9 with bronchiectasis, 1 with diffuse panbronchiolitis and 2 with RTI with chronic obstructive pulmonary disease, and the clinical efficacy rate was 78.4%. Causative organisms were isolated in 23 strains out of 20 patients, such as Staphylococcus aureus 4 strains, Staphylococcus epidermidis 1 strain, Streptococcus pneumoniae 1 strain, Branhamella catarrhalis 1 strain, Haemophilus influenzae 2 strains, Klebsiella pneumoniae 4 strains, Pseudomonas aeruginosa 6 strains, Pseudomonas sp. 1 strain, Acinetobacter calcoaceticus 1 strain, Acinetobacter sp. 1 strain and glucose non-fermentative Gram-negative rod 1 strain. An eradication rate of 70.6% was obtained. An overall eradication rate of main causative organisms in RTI including S. aureus, S. pneumoniae, H. influenzae and K. pneumoniae was 75.0%. Clinical adverse effects were observed in 5 patients, and these were eruption in 2, itching in 1, vomiting in 1 and drug fever in 1. Abnormalities in laboratory test results were observed in 8 patients. These disappeared or returned to normal values after completion or discontinuation of IPM/CS administration. IPM/CS appears to be a useful antibiotic for the treatment of RTI, especially severe infections.

Pharmacokinetic, bacteriological and clinical studies on cefpodoxime proxetil (CPDX-PR, CS-807), a newly developed oral cephem, were carried out in the treatment of infectious diseases in the field of pediatrics. 1. Since CPDX demonstrates very powerful antimicrobial actions against such Gram-negative bacilli as Escherichia coli, Salmonella sp., Klebsiella pneumoniae and Serratia sp., such Gram-positive cocci as Streptococcus pyogenes and Streptococcus pneumoniae, and beta-lactamase producing Branhamella catarrhalis and Haemophilus influenzae, this drug was thought to be useful for the treatment of pediatric infectious diseases when main causative bacteria in the field of pediatrics were taken into account. 2. When changes in blood and urine concentrations of CPDX following the administration of this drug at 3.7 mg/kg before meal were determined, Cmax and T1/2 were found to be 2.98 micrograms/ml at 2-hour and 1.73 hours, respectively; an urinary excretion rate in the first 6 hours and a maximum urine concentration were 32.5% and 52 micrograms/ml, respectively. 3. Clinically, 8 of 8 patients with the upper respiratory tract infections (100%), 28 of 29 patients with bronchitis and/or pneumonia (96.6%), 3 of 4 patients with otitis media (75%), 2 of 2 patients with sinusitis (100%), 3 of 3 patients with the skin soft tissue infections (100%), 1 of 1 patient with bacterial enteritis (100%) and 11 of 14 patients with urinary tract infections (78.6%) responded well to the treatment with CPDX-PR, showing a 91.8% efficacy rate in all the patients treated. 4. Bacteriologically, Staphylococcus aureus, Staphylococcus epidermidis, S. pyogenes, S. pneumoniae, E. faecalis, B. catarrhalis, H. influenzae, E. coli and Salmonella typhimurium were all eradicated from 5, 1, 4, 6, 1, 5, 5, 11 and 1 patient, respectively. An eradication rate in all the patients examined was 97.5% (39/40). 5. Gastrointestinal symptoms appeared as side effects in 2 of 71 patients (vomiting in 1 and diarrhea in 1), hence, an incidence of side effects was 2.8% (2/71). As for abnormal laboratory findings, eosinophilia, thrombocytosis and increases in GOT and GPT were observed in 3 of 39 patients examined (7.7%), 1 of 39 patients (2.6%) and 2 of 34 patients (5.9%), respectively. In addition, we also examined the effect of the drug on the hemostatic system, but found no changes upon the treatment. Based on these results, it appeared that CPDX-PR was a useful and safe drug in treatment of infectious diseases in the field of pediatrics when administered 2-3 times a day at a dose of 3-6 mg/kg.

The relationship of symptoms and signs to age and the reasons for consulting a physician were analyzed in 110 cases of culture-proven childhood bacterial meningitis. H. influenzae caused 74, meningococci 28, pneumococci 6 and streptococci 2 of the cases. Apart from fever (present in 94%), the most common symptoms according to age were as follows: 1-5 months: irritability (85%), 6-11 months: impaired consciousness (79%), 12 months or more: vomiting (82%) and neck rigidity (78%). Absence of neck rigidity at diagnosis was associated with young age (less than 12 months, P less than 0.001) and, in older children, to a short duration of symptoms (P less than 0.01) but not to the degree of CSF pleocytosis. Symptoms of meningitis caused by H. influenzae differed from those of meningococcal meningitis. Meningitis should be suspected in irritable or lethargic febrile children despite absence of neck rigidity. Fever and vomiting were the most frequent reasons for consulting a physician (60% and 31%, respectively). Despite the frequency and alarming character of irritability, impaired consciousness and neck rigidity, their presence led infrequently to a consultation (6%, 22% and 3%, respectively). Parental ignorance of such symptoms or of their importance may cause treatment delay, despite readily available medical services.

T-2588 was used on 55 patients with respiratory tract infections and 44 cases were evaluated; 23 patients with pneumonia, 12 patients with acute bronchitis, 2 patients with chronic bronchitis, 1 patient with diffuse panbronchiolitis and 6 patients with bronchiectasis with infection. Clinical effects of T-2588 were as follows; excellent in 6 and good in 28 patients. The efficacy rate was 77.3% (34/44). Bacteriological effects of T-2588 were prominent in 8 patients infected with B. catarrhalis, H. influenzae, K. pneumoniae and E. coli, but not in a patient infected with P. putida. The elimination rate was 90.0% (9/10 strains). As side effects, stomatitis, anorexia, diarrhea X vomiting and pruritus were observed in one patient each. Abnormal laboratory findings were observed in 4 patients with elevated GOT and/or GPT. These side effects and abnormal laboratory findings were not serious. The usefulness of T-2588 was 68.2% (30/44). Therefore, T-2588 is a useful drug and its effects are promising in clinical management of respiratory tract infections.

Cefotaxime (CTX) was administered to 117 pediatric patients. Although 26 of these patients were excluded from the clinical evaluation of the study because other antimicrobial agents were given concomitantly with CTX or because no infectious diseases were proved, these cases were evaluated for adverse effects of the drug. The remaining 91 cases were evaluated for clinical effect; pneumonia in 56 cases, septicemia in 5, suspected septicemia in 5, meningitis (aseptic cases included) in 3, urinary tract infection in 5 and other diseases in 17. No pathogenic organisms were identified in any of the pneumonia cases, even either by bacterial culture or other laboratory test methods. Pathogens of septicemia were E. coli in 3 cases, K. pneumoniae in 1 and E. agglomerans in 1. Those of urinary tract infections were E. coli in 3 cases, a mixed infection of S. aureus and an unidentified species of Gram-negative rods in 1, and unknown in 1. Clinical effectiveness rates of CTX were 78.6% in pneumonia and 100% in septicemia, suspected septicemia and urinary tract infections. One patient with purulent meningitis caused by H. influenzae was also treated with CTX successfully. Adverse reactions and abnormal laboratory findings were observed in 12 cases (12/117 = 10.3%); rash in 2 cases, vomiting in 1, abdominal pain in 1, diarrhea in 5, granulocytopenia and thrombocytopenia in 1, eosinophilia in 3 and elevation of liver enzymes (GOT and LDH) in 1.

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.

In an open, multicentre study, the clinical and bacteriological efficacy, safety and tolerance of azithromycin and roxithromycin were compared in a total of 204 adults with acute lower respiratory tract infections (LRTIs) [acute bronchitis, acute infectious exacerbations of chronic bronchitis (AIECBs), or pneumonia]. Following treatment with 500 mg/day azithromycin administered orally once daily for 3 days, a satisfactory clinical response of cure or improvement was recorded in 91/99 (91.9%) evaluable patients at the post-therapy evaluation (day 10-14). Of the 94 evaluable patients treated with roxithromycin (150 mg given orally twice daily for 10 days), 82 (87.2%) were classified as cured or improved at post-therapy. The main pathogens isolated before treatment were Staphylococcus aureus, Streptococcus pneumoniae, Streptococcus species, Haemophilus influenzae and Moraxella catarrhalis. In the 46 azithromycin-treated patients evaluated both clinically and bacteriologically, 92.0% of pathogens were eradicated; H. influenzae persisted in one azithromycin-treated patient with acute bronchitis who was classed as clinically improved. In the roxithromycin group, 81.1% of the pathogens were eradicated in 35 patients; S. aureus persisted in one clinically cured patient with acute bronchitis, and H. influenzae persisted in one patient with AIECB and one with pneumonia, and Haemophilus species in one with AIECB, who were all classified as clinically improved. Azithromycin was well tolerated with a lower incidence of adverse events than that recorded in the roxithromycin treatment group. Treatment was not discontinued due to adverse events in any of the azithromycin-treated patients, whereas two roxithromycin-treated patients were withdrawn from treatment due to vomiting and/or dyspepsia.

Post-tonsillectomy bacteremia is a well-recognized aetiological factor in streptococcal endocarditis, and prophylactic penicillin has been recommended to reduce its incidence in susceptible patients undergoing tonsillectomy. Recent studies have shown a change in the microflora and an increase in the number of penicillin-resistant organisms in the tonsils of patients undergoing tonsillectomy. The aim of this study was to assess the incidence of post-tonsillectomy bacteraemia, to identify the micro-organisms associated with it and to review the suitability of penicillin in prophylactic regimens. The relationship between positive blood cultures and several clinical parameters such as fever, vomiting, pharyngeal discomfort, or dysphagia was also analysed. Of the 102 patients included in the study, 41 (40.1%) had positive post-tonsillectomy blood cultures. Haemophilus influenzae were isolated from 23 (56%) of the positive cultures and Streptococcus viridans in 15 (36.5%). Twenty-five per cent of H. influenzae produced beta-lactamase and only 30% of streptococci of the viridans group were penicillin-sensitive. Positivity of the blood cultures was not related to fever, discomfort, surgical technique, type of tonsil, or any of the parameters studied. Bacteraemia seems to be related to traction of the tonsil before dissection rather than direct spread of bacteria into the opened vessels. Using a beta-lactamase stable antibiotic instead of penicillin for prophylaxis would be more appropriate.

This study analysed the bacterial aetiology and outcome of childhood meningitis observed over an 11-year period. Charts of 70 children with this diagnosis were reviewed. Three children were under 1 month of age, five were between 1 and 3 months and 60 were between 3 months and 5 years. The remaining two were over 5 years. There were 36 females and 34 males. The presenting symptoms in decreasing order of frequency were fever 86%, vomiting 29%, poor feeding 19%, seizure 14% and lethargy 14%. Aetiological organisms were as follows: Haemophilus influenzae 66%, Streptococcus pneumoniae 24%, Neisseria meningitidis 4%, Group B Streptococci 4%, and Staphylococcus aureus 2%. All H. influenzae isolates except one were sensitive to ampicillin. None of the S. pneumoniae isolates were resistant to penicillin. Complications occurred in 26% of the patients and included subdural effusion 23%, hearing loss 14%, seizure disorder 10%, developmental delay 9%, hydrocephalus 6% and motor deficit 30%. One patient died. Among H. influenzae cases, one of the 15 patients treated with steroids developed hearing loss. In contrast, four out of 31 who did not receive steroid therapy suffered from hearing loss. Haemophilus influenzae type b is the predominant cause of childhood bacterial meningitis in Saudi Arabia. Universal H. influenzae type b vaccination for children is highly recommended.
