The clinical studies with azithromycin fine granules and capsules were conducted during the period from March 1993 to October 1994. Cmax's in 16 patients who received 10 mg/kg fine granules, were 0.29 +/- 0.24 microgram/ml, T1/2's were 42.0 +/- 11.8 hours, and AUC 0 approximately infinity's were 10.72 +/- 5.00 micrograms.hr/ml. The clinical results for azithromycin fine granule and capsules 10 mg/kg once daily for 3 days are as follows. The efficacy rate of fine granules, combining both "Excellent" and "Good", for pneumoniae where causative pathogenes were identified, was 95.3%, and for those which had failed to respond to previous chemotherapies, was 94.6%, respectively. The efficacy rate of capsules for 3 to 5 days was 100% in 40 cases where causative pathogenes were identified. Adverse reactions were found in 2.5%(fine granules) and in 5.4%(capsules) in cases eligible for evaluation. Abnormal changes in laboratory test were as follows: decrease of WBC by 5.6%(fine granules) and 9.3%(capsules) and increase in eosinophils by 7.1%(fine granules) and 11.4% (capsules). 59.8% of the patients claimed that the azithromycin 10% fine granules product was "easy to take". The result of a questionnaire on parents' demand on the improvement of antibiotics, showed that most concern was on the drug frequency(preferably once or twice daily) and the drug administering period(preferably short: 3 days). With regard to the efficacy, safety and compliance, it can be concluded that Azithromycin is one of the useful therapeutic regimens in the treatment of pediatric infections.

MAC prophylaxis in the era of polypharmacy.
Sawhney N.
Infectious Disease Consultants of Wisconsin, Milwaukee 53215, USA.
In the advanced stages of AIDS, patients are increasingly susceptible to disseminated Mycobacterium avium-intracellulare (MAC) infection, causing significant morbidity and mortality. It has been shown that prophylaxis against this infection is effective in reducing the incidence as well as the symptoms of MAC. Although chemoprophylaxis against MAC is a standard recommendation, it is not always carried out due to a variety of reasons. Several agents are now approved for this purpose, adding to the complexity of the decision to start the prophylaxis. This article reviews the need for prophylaxis against MAC, and considers the different agents available, with the aim of helping readers come to an informed decision about starting MAC prophylaxis in their patients. This issue will be of rising importance with the effective prevention of other opportunistic infections in patients with advancing immune deficiency.

A multicenter study was conducted to assess the interlaboratory reproducibility of susceptibility testing of Mycobacterium avium complex (MAC) by broth microdilution using two different media (cation-adjusted Mueller-Hinton broth with 5% oleic acid-albumin-dextrose-catalase and 7H9 broth with casein) and by macrodilution using the BACTEC 460TB and 12B media at pH 6.8 and 7.3 to 7.4. Ten well-characterized strains of MAC (four macrolide susceptible, six macrolide resistant) were tested against clarithromycin and azithromycin (the latter only by BACTEC 460TB, pH 6.8). At each site, strains were tested against clarithromycin three times on each of three separate days (nine testing events per isolate) by using a common lot of microdilution trays and BACTEC 12B medium, pH 6.8; strains were tested once on three separate days against clarithromycin in 12B medium at pH 7.3 to 7.4 and against azithromycin. Agreement among MICs (i.e., mode +/- 1 twofold dilution) was 100% for all strains and both drugs when BACTEC 460TB was used, regardless of the pH of the medium, but varied when microdilution with either medium was used, particularly with susceptible strains. Agreement based on interpretive category, with NCCLS-recommended breakpoints, was 100% for all strains with the BACTEC 460TB method (both drugs and both pH values) and with microdilution using 7H9 broth. With microdilution and Mueller-Hinton broth, agreement by interpretive category was 100% for eight isolates and >90% for two; errors occurred only in laboratories where personnel had minimal experience with this technique. MAC susceptibility testing may be performed by broth macrodilution or microdilution at either pH, with NCCLS-recommended interpretive breakpoints. However, because visual interpretation of broth microdilution end points is subjective, it is more prone to reader error; therefore, this method requires greater expertise than the BACTEC 460TB. Both techniques require appropriate validation and continued documentation of proficiency.
