BACKGROUND Rasburicase (recombinant urate oxidase) has been proven to be an effective therapy for prevention of tumour lysis syndrome (TLS). The recommended daily dosing regimen of rasburicase is 0.2 mg/kg/day for 5 days which is expensive and unaffordable to many patients in the developing countries. The purpose of the present study was to evaluate the effect of single 1.5 mg dose rasburicase in the management of tumour lysis syndrome. METHODS This is a follow-up study done at our institute. Fifty (50) patients with tumour lysis syndrome who received rasburicase from August 2015 to January 2020 were enrolled in this study RESULTS Single dose of rasburicase is effective in decreasing serum uric acid level in significant number (N = 41) of patients. Percentage of patients having uric acid less than 7 mg after single dose of rasburicase in 48 hours - 82.9 % (N = 34) while 17 % (N = 7) were found to have uric acid levels of more than 7 mg/dl. The percentage of patients with uric acid levels more than 7 mg/dl reduced from 36.5 % after 24 hours to 17 % after 48 hours. This indicates that the uric acid levels show a declining trend even after 24 hours without giving an additional dose of rasburicase. There was no relationship between uric acid levels at 24 hours and percentage change in creatinine level from baseline to 24 hours (correlation coefficient (r) = -0.047, P = 0.770. Patients who required additional dose (N = 9) had high base line value of uric acid and their high value was maintained over the follow up period of three days. Patients with pre exiting kidney disease and high level of baseline uric acid also needed dialysis (N = 3). CONCLUSIONS In majority of patients, a single 1.5 mg dose of rasburicase is an effective way to reduce raised uric acid in appropriate circumstances.

AbstractBackgroundInfliximab is an effective salvage therapy in acute severe ulcerative colitis; however, the optimal dosing strategy is unknown. We performed a systematic review and meta-analysis to examine the impact of infliximab dosage and intensification on colectomy-free survival in acute severe ulcerative colitis.MethodsStudies reporting outcomes of hospitalized steroid-refractory acute severe ulcerative colitis treated with infliximab salvage were identified. Infliximab use was categorized by dose, dose number, and schedule. The primary outcome was colectomy-free survival at 3 months. Pooled proportions and odds ratios with 95% confidence intervals were reported.ResultsForty-one cohorts (n = 2158 cases) were included. Overall colectomy-free survival with infliximab salvage was 79.7% (95% confidence interval [CI], 75.48% to 83.6%) at 3 months and 69.8% (95% CI, 65.7% to 73.7%) at 12 months. Colectomy-free survival at 3 months was superior with 5-mg/kg multiple (≥2) doses compared with single-dose induction (odds ratio [OR], 4.24; 95% CI, 2.44 to 7.36; P < 0.001). However, dose intensification with either high-dose or accelerated strategies was not significantly different to 5-mg/kg standard induction at 3 months (OR, 0.70; 95% CI, 0.39 to 1.27; P = 0.24) despite being utilized in patients with a significantly higher mean C-reactive protein and lower albumin levels.ConclusionsIn acute severe ulcerative colitis, multiple 5-mg/kg infliximab doses are superior to single-dose salvage. Dose-intensified induction outcomes were not significantly different compared to standard induction and were more often used in patients with increased disease severity, which may have confounded the results. This meta-analysis highlights the marked variability in the management of infliximab salvage therapy and the need for further studies to determine the optimal dose strategy.
