Cefprozil granule preparation was administered orally to 16 patients (ages ranging 8 months to 9 years and 6 months) with pediatric bacterial infections at daily dose levels between 29.4 and 35.7 mg/kg divided into 3 or 4 doses. The following results were obtained. 1. Sixteen patients including 5 with pharyngitis, 3 with tonsillitis, 3 with lacunar tonsillitis, 2 with pneumonia, 2 with contagious impetigo and 1 with scarlet fever were treated. Clinical effects were excellent in 9 cases and moderate in 7, with an overall efficacy rate of 100%. 2. Organisms suspected as pathogens included 17 strains (10 strains of haemophilus influenzae, 2 of Haemophilus parainfluenzae, 3 of Streptococcus pyogenes and 2 of Staphylococcus aureus). Bacteriologically, eradication of pathogens were observed for 11 strains, but no changes were obtained for 5 (all Haemophilus), and unknown results were obtained for 1, thus the eradication rate was 68.8%. 3. No side effects were observed. Abnormal laboratory test results included 2 cases of increase in platelets, and 2 of increase in eosinophils, but those were not significant. 4. No refusal of the drug occurred due to its taste or odor.

Therapeutic effects of cefprozil (CFPZ, BMY-28100), a new cephalosporin, were examined in various infectious diseases in children. Clinical efficacy rates were 50% (2/4) in acute bronchitis, 80% (4/5) in pharyngitis, 0% in laryngitis, 100% (7/7) in tonsillitis, 100% (8/8) in impetigo contagiosa, furuncle and posthitis. Hence, the overall efficacy rate was 84% (21/25). Adverse effects were observed in 1 case with slightly elevated serum GOT and GPT. Changes in serum concentrations and urinary excretion of CFPZ were examined in 4 and 2 children without infection, respectively. T 1/2 values obtained were between 1 hour to 2 hours (bioassay). Six hour recovery rates in urine were 51.8% and 77.8% (bioassay). CFPZ was considered to be a safe and useful drug in treating various infectious diseases in children.

Cefprozil (CFPZ), a newly developed oral cephalosporin in a fine granular form for pediatric use, was administered to children with bacterial infections. MICs were determined for 6 drugs including CFPZ, cephalexin (CEX), cefaclor (CCL), ampicillin (ABPC), methicillin (DMPPC) and cloxacillin (MCIPC) against the following 84 strains isolated from cases to which CFPZ was administered; 55 strains of Gram-positive cocci (GPC) including 2 strains of Staphylococcus aureus, 49 strains of Streptococcus pyogenes, 4 strains of Streptococcus pneumoniae, and 29 strains of Gram-negative bacilli (GNB) including 10 strains of Haemophilus influenzae, 18 strains of Escherichia coli, and 1 strain of Proteus mirabilis. MIC determination of these strains was done with an inoculum size of 10(6) CFU/ml. In pharmacokinetic studies, serum concentrations, urinary concentrations and urinary recovery rates were investigated using bioassay and high-performance liquid chromatography (HPLC). CFPZ was orally administered 30 minutes before meals to 9 children with ages ranging from 7 years and 1 month to 12 years and 3 months. Three groups of 3 children were tested with doses of 4.0, 7.5 and 15.0 mg/kg, respectively. In addition to the above, clinical and bacteriological studies were performed in a total of 160 cases consisting of children with ages ranging 5 months to 12 years and 5 months. A mean dose of 8.6 mg/kg in 3-4 divided doses (130 cases of t.i.d. and 30 cases of q.i.d.) was administered for an average of 7 days. The 160 cases included 34 cases of pharyngitis, 5 cases of tonsillitis, 8 cases of acute bronchitis, 8 cases of pneumonia, 52 cases of scarlet fever, 4 cases of acute purulent otitis media, 47 cases of urinary tract infection, 1 case of purulent lymphadenitis and 1 case of posthitis. Adverse reactions and abnormal clinical laboratory test results were also examined in 166 cases, including 6 cases excluded from the evaluation of clinical efficacy. The results obtained are summarized as follows: 1. With regard to GPC, MICs of CFPZ against 2 strains of S. aureus were 0.78 or 1.56 micrograms/ml and CFPZ showed the second highest activity to MCIPC. MICs of CFPZ against 49 strains of S. pyogenes were all less than 0.025 micrograms/ml.(ABSTRACT TRUNCATED AT 400 WORDS)

Cefprozil (CFPZ, BMY-28100) is a new oral cephem antibiotic without an ester linkage. Pharmacokinetic and clinical studies using CFPZ 10% fine granules were performed in pediatric patients. 1. Pharmacokinetic investigation Peak serum concentrations of CFPZ after dose of 7.5 mg/kg and 10 mg/kg were, respectively, 3.65 +/- 0.24 micrograms/ml and 6.38 +/- 3.23 micrograms/ml at 1-2 hours. The average half-life with 7.5 mg/kg administration was 0.90 +/- 0.16 hours and that with 10 mg/kg was 1.29 +/- 0.50 hours. The urinary excretion of CFPZ was about 45% (35.3-50.0%) in 6 hours. 2. Clinical investigation Enrolled in the study were 22 patients including 4 with pharyngitis, 3 with tonsillitis, 3 with bronchitis, 5 with pneumonia, 4 with urinary tract infection, and 1 each with pertussis, purulent lymphadenitis and otitis media. Responses were excellent in 14 patients, good in 5 patients and fair in 1 patient. In the assessment of the bacteriological efficacy, 8 out of 17 strains of organism identified previous to the treatment were eradicated, 5 strains were found replaced by other bacteria and 4 strains persisted, hence the eradication rate was 76.5%. 3. No adverse reactions attributable to the drug were observed. From the above results, it has been concluded that CFPZ is a highly effective and safe agent for moderate respiratory and urinary tract infections in children.

A randomized control trial was designed to compare the efficacies of spiramycin given one gram twice daily and erythromycin given 500 mg thrice or four times daily in the treatment of acute exudative tonsillitis in adults whose ages were over 13 years old from January 1989 to January 1991 at a community clinic. A total of 120 cases were enrolled in the study. Fifty-three patients received spiramycin while 67 received erythromycin. Group A beta-hemolytic streptococci (GABHS), S. aureus, and positive titer of Mycoplasma pneumoniae were detected in 19, 47 and 8 per cent in spiramycin group and 21, 36 and 11 per cent in erythromycin group respectively. GABHS were totally eradicated on day 3 of treatment in both groups through eradication of S. aureus was slightly slower initially in the spiramycin group. Marked improvement was similarly achieved in both groups after 3 days of therapy. Dyspepsia was felt in 34.4 and 8.2 per cent of erythromycin and spiramycin groups respectively but was tolerable by most patients. We concluded that spiramycin given twice daily was as effectively as conventional erythromycin but spiramycin is more convenient to administer and causes much less gastro-intestinal side-effect.

The prevalence of two types of Epstein-Barr virus (EBV) in Japan was studied by using the polymerase chain reaction (PCR). The U2 region encoding EBV nuclear antigen 2 (EBNA-2) was chosen as the target of amplification. Consensus primers were synthesized from sequences common to the two types but encompassing a large stretch of deletion in the sequence of type 1 EBV. The primers were capable of amplifying both types at the same time but allowed differentiation of each type by the size of the amplification products. Thus we could carry out detection and typing of EBV in a one-step PCR. EBV was detected in mouth washings of 21 (23%) of 91 seropositive healthy adults. Twenty samples (22%) contained type 1 and only one (1%) type 2. Seventy-nine patients suffering from various types of tonsillitis were also studied. EBV was detected in mouth washings of 37 patients (47%). Thirty-four (43%) contained type 1 and three (4%) type 2. Double infection was not seen in either healthy donors or patients. These results indicate that type 1 EBV is highly dominant and the type 2 variant is quite rare in Japan.

Cytomegalovirus (CMV) infection after heart transplantation (HTx) is a severe complication, which leads to long treatment and hospital stay. Even if prophylactic therapy with anti-CMV IgG antibodies is performed, there is a high incidence of infection, especially when the heart from a CMV positive donor is transplanted to a CMV negative recipient (high risk constellation). This study evaluates the prophylactic antiviral therapy with ganciclovir in CMV high risk constellation at HTx. Out of 108 HTx, 29 CMV negative recipients (IgG and IgM) received a heart from a CMV positive donor (IgG pos., IgM neg.). The control group (CO) (n = 8) was treated with anti-CMV IgG antibodies (Cytotect 2 ml/kg at day 0, 1, 2, 7, 14, 21,), whereas the study group (GAN) (n = 13) was treated with ganciclovir (7.5 mg/kg single dose n = 8, or 5 mg/kg in twice daily doses n = 5 from day 1 to 14). Urea, creatinine, white blood cell count and platelet count was controlled daily. No side effects on renal and bone marrow function were noted. Therapy was well tolerated. Both groups had similar immunosuppressive protocol (prophylactic cytolysis, prednisone, azathioprine and cyclosporin A) and were similar in age, sex, preoperative diagnosis and NYHA class. Seroconversion for CMV (IgM and IgG) was observed in 75% of CO and 31% of GAN (p less than 0.05). Clinical manifestations of CMV infection started in the second month after HTx with fever in both groups CMV-organ manifestations developed in 50% (or 67% of infected) in CO (enterocolitis 2, pneumonitis 3, tonsillitis 1), and in 15% (or 50% of infected) in GAN (pneumonitis 2, epididymitis 1) NS.(ABSTRACT TRUNCATED AT 250 WORDS)

The new fluoroquinolone antimicrobial temafloxacin shows good penetration into a range of body tissues and fluids, after single or repeated oral administration to healthy volunteers and patients undergoing various procedures. Temafloxacin concentrations in respiratory tissues and fluids, nasal secretions, tonsils, prostate, semen, bone and blister fluid were similar to, or greater than, concurrent serum concentrations. Penetration into sinus secretions and cerebrospinal fluid is less marked; nevertheless, temafloxacin concentrations of approximately 2.4 and 1 mg/L, respectively, were achieved. Concentrations of temafloxacin observed in these tissues and fluids exceed the minimum concentrations required to eradicate the majority of bacterial pathogens associated with respiratory infections, tonsillitis, sinusitis, prostatitis, bone infections and meningitis. Since elimination of temafloxacin occurs by the renal route, high concentrations of the drug are also found in the urine. Biliary excretion of temafloxacin accounts for about 3% and leads to high biliary concentrations of the drug.

The presence of human papillomavirus (HPV) DNA was assessed in biopsies of tonsillar carcinomas (n = 10) and cases of tonsillitis (n = 7), serving as controls, by general-primer-mediated PCR (GP-PCR). All carcinomas appeared HPV-positive, whereas all cases of tonsillitis were HPV-negative. Additional type-specific PCR for HPV 6, 11, 16, 18, 31 and 33 revealed that 4 carcinomas contained HPV 16 DNA, 4 contained HPV 33 DNA and 1 contained an HPV 16/33 double infection. False positivity was excluded by additional Southern blot analysis of type-specific PCR-positive samples (n = 4). Further characterization of GP-PCR products by sequence analysis revealed that 2 carcinomas contained still uncharacterized HPV genotypes; one of these also contained HPV 33 DNA and one was negative by type-specific PCR. Application of RNA PCR revealed expression of HPV 16 or HPV 33 E7 encoding spliced E6*1 transcripts in all tonsillar carcinomas (n = 4) examined. Additional non-radioactive RNA in situ hybridization performed on 3 biopsies revealed the presence of HPV 16 or HPV 33 E7 transcripts exclusively localized within the carcinoma cells, whereas stroma stained negative. These findings strongly support a role for certain HPV types in the pathogenesis of tonsillar carcinomas.

The distribution of lymphoid cells in the mantle zone, germinal center, interfollicular area, and subepithelial area of the tonsil was evaluated quantitatively by image analysis in 66 subjects aged 3 to 66 years. The number of Ig-positive cells in the tonsil decreased with advancing years in all compartments. This inverse correlation to age was statistically significant for IgD-, IgM-, and IgG-positive cells. For T-cells, overall change of each T-cell subset with age was smaller than those of Ig-positive cells. An age-related marked decline was seen for CD4-positive cells only in the subepithelial area and for CD8-positive cells only in the interfollicular area. Ki-67-positive cells, cells undergoing active division, were mainly found in the germinal centers and also diminished with advancing years. Patients with frequent episodes of tonsillitis demonstrated a significant increase of IgD-positive cells and IgG-positive cells in interfollicular and subepithelial compartments and a decrease of CD4-positive T-cells in the germinal centers and subepithelial areas. These results suggest that the tonsillar involution with age is immunologically associated in all compartments with the decrease of Ig-positive cells and Ki-67-positive activated cells resulting in a relative increase of T-cell subsets. The method of image analysis provides a novel and unique approach for quantitative immunohistological study of the tonsil.
