A 2.5-year retrospective study of pyogenic meningitis in hospitalized children in Kelantan was carried out with regard to aetiology, clinical features, investigation, treatment and outcome. There were 58 children with 43 cases (74.1%) occurring below the age of 1 year. Frequent presenting symptoms included fever (98.3%), fits (77.6%), anorexia (39.7%), vomiting (34.5%) and drowsiness (12.1%). On admission, 37 (63.7%) had neck stiffness, 10 (17.2%) had Kernig's sign and 32 (55.2%) had coma. CSF cultures were positive for Haemophilus influenzae in 29 (50%), Streptococcus pneumonia in 13 (22.4%) and Neisseria meningitidis in 3 (5.2%). The antibiotic sensitivity profiles showed that the three main organisms were 100% sensitive to Chloramphenicol, Streptococcus pneumoniae was 100% sensitive to penicillin, Neisseria meningitidis was 100% sensitive to penicillin and ampicillin, and Haemophilus influenzae was 90% sensitive to penicillin and ampicillin. The total hospital mortality was 18.9%. All but two of the eleven deaths occurred in children younger than 1 year. Nineteen of the 35 (54.3%) survivors attended for at least one follow-up after discharge from hospital. Of these 19 children, 47.4% had neurological sequelae.

In the present study the feed and water consumption and pharmacokinetic parameters of orally administered oxytetracycline were compared in clinically healthy pigs and in the same pigs following a challenge with Actinobacillus (Haemophilus) pleuropneumoniae toxins. Endobronchial challenge with A. pleuropneumniae toxins was accompanied by anorexia, increased lassitude, labored breathing, fever, and increased white blood cell counts. Pleuropneumonia was evident in all pigs on autopsy. Following the challenge, both feed and water consumption were markedly reduced. In contrast to recommendations in the literature, it is concluded that drugs should not be administered to pneumonic pigs via water. In healthy pigs the oral bioavailability of oxytetracycline (50 mg/kg), given on an empty stomach, was 4.8% and the elimination half-life (t1/2 beta) was 5.92 h. After challenge, the pigs showed great variation in oxytetracycline plasma concentrations. In addition, the mean computed elimination rate constant (beta), t1/2 beta, the area under the plasma concentration-time curve (AUC), and clearance in pneumonic pigs differed significantly (P less than .05) from the values found in healthy pigs. The elimination half-life (t1/2 beta), AUC, and volume of distribution (Vd area) were increased. In diseased pigs the mean of maximum plasma concentrations (.87 micrograms/ml) was reached after 7 h, in contrast to 1.74 h (1.87 micrograms/ml) in the healthy pigs.

The safety and immunogenicity of a vaccine against Haemophilus influenzae type b consisting of purified polyribosylribitolphosphate conjugated to tetanus toxoid (PRP-T) was evaluated in 278 Chilean infants who were randomly assigned to one of three treatment groups: Group A, PRP-T mixed with diphtheria-tetanus toxoids-pertussis (DTP) vaccine in a single syringe and given as a single inoculation in one arm and placebo in the other arm; Group B, PRP-T given in one arm and DTP in the other arm; Group C, DTP given in one arm and placebo in the other. Infants were immunized at 2, 4 and 6 months of age and examined daily for 4 days after each immunization; serum PRP antibodies were measured at baseline and 2 months after each dose. The only adverse systemic reaction attributable to PRP-T beyond that caused by DTP alone was a 7 to 20% increase in febrile responses in the first 24 hours after the first and second doses of vaccine; the fevers were largely low grade and not accompanied by increased irritability, diminished activity or loss of appetite, compared with the group who received DTP without PRP-T. After the first dose 72% of infants who received PRP-T combined with DTP and 67% who received it in a separate arm attained antibody concentrations greater than or equal to 0.15 micrograms/ml. After two doses of PRP-T, 93 and 95%, respectively, had concentrations greater than or equal to 0.15 microgram/ml and after three doses 100% of infants who received PRP-T had such titers.(ABSTRACT TRUNCATED AT 250 WORDS)

Clinical usefulness of cefixime (CFIX), a new oral cephalosporin antibiotic, in pediatric field was investigated. The results obtained were summarized as follows. 1. The clinical efficacy of CFIX was investigated in a total of 138 children including 49 with upper respiratory tract infections (RTI), 22 with acute bronchitis, 18 with pneumonia, 19 with scarlet fever and 21 with urinary tract infections (UTI). 2. Clinical effectiveness was excellent in 58, good in 60, fair in 14 and poor in 3, with an overall efficacy rate of 87.4%. The efficacy rate classified according to types of infection were 85.7% in upper RTI, 89.5% in acute bronchitis, 94.4% in pneumonia, 78.9% in scarlet fever, and 90.5% in UTI. 3. Out of the suspected causative organisms, 43 strains of a total of 50 strains isolated were eradicated. The bacteriological eradication rate was 86.0%. (Haemophilus influenzae 100%, Haemophilus parainfluenzae 100%, Streptococcus pyogenes 88.5%, Escherichia coli 85.7%). 4. One hundred forty four children were analyzed for side effect. Side effects were observed in 2 children (1.4%) with diarrhea in 1 and anorexia in another. Abnormal laboratory test results were recorded in 4 children (3.3%). The above results suggest that CFIX is a very useful new oral cephalosporin for the treatment of bacterial infections in children.

A total of 29 patients with pediatric infections was treated orally with 21.4-44.4 mg/kg/day of rokitamycin (RKM) dry syrup. The obtained results are summarized as follows. 1. Clinical responses to RKM in 24 evaluable patients were excellent in 2 and good in 3 of 5 patients with tonsillitis and laryngitis; excellent in 3 and good in 5 of 8 patients with bronchitis; excellent in 3, good in 2 and fair in one of 6 patients with bronchopneumonia; excellent in 2 and good in the other of 3 patients with psittacosis; and excellent in 2 of 2 patients with Campylobacter colitis. The overall efficacy rate was 95.8%. 2. Bacteriological responses to the drug were: reduction in 1 and no change in the other of 2 strains of Streptococcus pyogenes; eradication of a strain of Streptococcus pneumoniae and 2 strains of Staphylococcus aureus; eradication of 2 and no change in 3 of 5 strains of Haemophilus influenzae; and eradication of 2 out of 2 strains of Campylobacter spp. 3. Diarrhea was complained of as an adverse reaction to the RKM medication by 1 patient, abdominal pain was reported by another, and anorexia by another of the 27 patients treated. Laboratory examination was performed on some patients, but not abnormal test values were found except in 1 case showing an increase in platelet count from 27.6 to 78.2 X 10(4)/mm8. The results suggested that RKM dry syrup might be a very useful and safe drug for the treatment of pediatric infections.

This study tested the protective activity of antibodies to the LPS core of Haemophilus influenzae (Borrelli et al., Infect. Immun. 1995;63: 3683-92) in a hematogenous meningitis model. Meningitis was established by intraperitoneal inoculation of infant rats with H. influenzae type b (Hib). The severity of infection was determined by daily assessment of mortality, symptoms of disease and weight changes. Mortality occurred rapidly after infection with 10(5)cfu/rat and most animals died within 24 h. At a lower infection dose (10(4)cfu/rat) the rats survived, but developed symptoms of disease such as tremor, hypothermia, lethargy and anorexia within 12-72 h post challenge. Surviving animals showed decreased weight gain. Bacteremia was detected by daily blood-cultures in 10/10 rats and cleared 6 days after inoculation. The monoclonal anti-LPS antibody MAHI 3 was used in passive protection studies. MAHI 3 increased the survival in the high inoculum group (10(5)cfu/rat) from 10-17% in control animals to 60-90%. At the lower inoculum concentration (10(4)cfu/rat) MAHI 3 treatment reduced the symptoms and blood counts. Intraperitoneal injection of MAHI 3 was more effective than intranasal injection as shown by the effect on bacteremia. We conclude that anti-LPS antibodies can protect against mortality caused by hematogenous Hib infections in infant rats.

An open, randomised, multicentre trial was performed to compare the reactogenicity and safety profile of the administration of a hexavalent diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated polio (DTPa-HBV-IPV) vaccine administered in one injection mixed with Haemophilus influenzae type b (Hib) conjugate vaccine (Group 1) with that of a pentavalent DTPa-IPV vaccine mixed with a Hib vaccine (DTPa-IPV/Hib), simultaneously administered with HBV (Group 2) in two injections in opposite thighs, as a primary vaccination course, to healthy infants at 2, 4 and 6 months of age. A total of 235 completed the study, 120 from Group 1 and 115 from Group 2. Blood samples (pre-vaccination and 1 month after the third dose) were obtained from a subset of infants (Group 1: 40; Group 2: 31) to assess the immune response to vaccination. Local and general solicited symptoms were recorded by parents on diary cards. Seven hundred and five diary cards (Group 1: 360; Group 2: 345) were collected. The clinically relevant and most commonly reported local reaction was pain (infant cried when the limb was moved) in 2.5% (Group 1) and 1.2% (Group 2) of diary cards. Fever was more frequently reported in Group 1 (21% of diary cards) than in Group 2 (12% of diary cards). However only 3 and 2% of doses in Groups 1 and 2, respectively, were responsible for a rectal temperature between 38.6 and 39.5 degrees C and only one case (Group 2) had > or =39.5 degrees C. Other clinically relevant general symptoms were rarely recorded: irritability (2-2.8%), loss of appetite (0.3-0.6%) and drowsiness (0.3-0.3%). All subjects included in the immunogenicity analysis had seroprotective titres to diphtheria, tetanus, polio virus types 1 and 3, Hib. Almost all subjects were seroprotected for anti-polio type 2 and hepatitis B (with the exception of 1 subject in Group 1 for each antigen). The vaccines response rates to pertussis antigens were over 97 and 90% in Groups 1 and 2, respectively. This study shows that, from a clinical perspective, the DTPa-HBV-IPV/Hib vaccine given in a single injection has a similar reactogenicity and safety profile to that of two licensed vaccines (DTPa-IPV/Hib, HBV) given in two simultaneous injections to infants at 2, 4 and 6 months of age. This is a valuable advantage, since in some countries, such as Spain and the UK, an additional injection (for the administration of meningococcal C conjugate vaccine) has been recently included in the infants' vaccination calendars.

Cardiobacterium hominis, a member of the HACEK group (Haemophilus parainfluenzae, Haemophilus aphrophilus, and Haemophilus paraphrophilus, Actinobacillus actinomycetemcomitans, C. hominis, Eikenella corrodens, and Kingella species), is a rare cause of endocarditis. There are 61 reported cases of C. hominis infective endocarditis in the English-language literature, 15 of which involved prosthetic valve endocarditis. There is one reported case of C. hominis after upper endoscopy and none reported after colonoscopy. Presented here are two cases of C. hominis prosthetic valve endocarditis following colonoscopy and a review of the microbiological and clinical features of C. hominis endocarditis. Patients with C. hominis infection have a long duration of symptoms preceding diagnosis (138+/-128 days). The most common symptoms were fever (74%), fatigue/malaise (53%), weight loss/anorexia (40%), night sweats (24%), and arthralgia/myalgia (21%). The most common risk factors were pre-existing cardiac disease (61%), the presence of a prosthetic valve (28%), and history of rheumatic fever (20%). Of the 61 cases reviewed here, the aortic valve was infected in 24 (39%) and the mitral valve in 19 (31%) patients. The average duration of blood culture incubation before growth was detected was 6.3 days (range, 2-21 days). Complications were congestive heart failure (40%), central nervous system (CNS) emboli (21%), arrhythmia (16%), and mycotic aneurysm (9%). C. hominis is almost always susceptible to beta-lactam antibiotics. Ceftriaxone is recommended by the recently published American Heart Association guidelines. The prognosis of C. hominis native valve and prosthetic valve endocarditis is favorable. The cure rate among 60 patients reviewed was 93% (56/60). For prosthetic valve endocarditis, the cure rate was 16/17 (94%). Valve replacement was required in 27 (45%) cases.

Diagnostic criteria for acute otitis media include rapid onset of symptoms, middle ear effusion, and signs and symptoms of middle ear inflammation. Streptococcus pneumoniae, Haemophilus influenzae, and Moraxella catarrhalis are the most common bacterial isolates from the middle ear fluid of children with acute otitis media. Fever, otalgia, headache, irritability, cough, rhinitis, listlessness, anorexia, vomiting, diarrhea, and pulling at the ears are common, but nonspecific symptoms. Detection of middle ear effusion by pneumatic otoscopy is key in establishing the diagnosis. Observation is an acceptable option in healthy children with mild symptoms. Antibiotics are recommended in all children younger than six months, in those between six months and two years if the diagnosis is certain, and in children with severe infection. High-dosage amoxicillin (80 to 90 mg per kg per day) is recommended as first-line therapy. Macrolide antibiotics, clindamycin, and cephalosporins are alternatives in penicillin-sensitive children and in those with resistant infections. Patients who do not respond to treatment should be reassessed. Hearing and language testing is recommended in children with suspected hearing loss or persistent effusion for at least three months, and in those with developmental problems.

Hepatitis B and Haemophilus influenzae type b (Hib) infections are major public health problems in developing countries, including India. Hence, combination vaccines containing DTwP, recombinant hepatitis B and Hib conjugate vaccines have been developed. Here, we report a Phase IV study which assessed safety and reactogenicity of a new DTwP-HepB+Hib vaccine. Three doses of DTwP-HepB+Hib vaccine (Pentavac, Serum Institute of India Ltd) or Tritanrix-HB+Hib (GlaxoSmithKline Beecham) were administered to infants at 6, 10 and 14 weeks of age in 2:1 ratio. The subjects were followed till one month after the third dose for safety assessment. Adverse events were captured in structured diaries and physical examinations were performed on each visit. The study was conducted in 1510 infants. Both vaccines caused injection site local and systemic reactions and the incidence was similar in both the groups. The incidence of local solicited reactions was: tenderness 35.9 %-33.6 %; redness 18.1 %-17.2 %; swelling 23.7 %-22.4 %; induration 12.8 % -13.7 %. The percentage of systemic solicited reactions were: diarrhea 2.2 %-2.2 %; drowsiness 3.3 %-3.4 %; fever 14.0 %-11.2 %; irritability 28.1 %-25.4 %; loss of appetite 6.6 %-5.6 %; persistent crying 17.7 %-15.7 %; vomiting 3.5 %-3.0 %. No serious adverse event was caused by the vaccines. The new DTwP-HepB+Hib combination vaccine showed similar safety profile to that of an imported vaccine in Indian infants.
