The total antibiotic treatment duration was 20 weeks. Of 101 patients followed, 10 (10% 95% confidence interval [CI] 4.9—17.5%) subsequently relapsed: 2 of 52 patients (4%) inthe oral ‘conventional’ group, and 8 of 49 patients (16%) receiving oral co-amoxiclav. This compares with a relapse rate of 23% in our previous study of 8 weeks’ totaltherapy. Only 50% of patients complied with the 20 weeks’ treatment regimen and poor compliance proved the most significant risk factor for subsequent relapse (relative risk [RR] 4.9, 95% CI 1.2—20.3). Neither the presence of known underlying disease nor choice of initial patenteral treatment was significantly associated with a higher risk of relapse. Co-amoxiclav is saferand better tolerated, but may be less effective (RR of relapse 0.4, 95%CI 0.2—1.2) thanthe oral ‘conventional’ regimen. The minimum duration of total treatment with either regimen should be 12—20 weeks, depending on clinical progress. © 1995 Oxford University Press.Mahidol UniversityImmunology and MicrobiologyMedicineA prospective comparison of co-amoxiclav and the combination of chloramphenicol, doxycycline, and co-trimoxazole for the oral maintenance treatment of melioidosisArticleSCOPUS10.1016/0035-9203(95)90104-3
