Maintaining a clinically appropriate tacrolimus trough and judicious antibiotic use and selection for UTI treatment could potentially reduce CDI in the kidney transplant population.

Rasburicase is a recombinant urate oxidase enzyme administered for treatment of hyperuricemia associated with tumor lysis syndrome. Studies demonstrate effectiveness of single fixed-dose rasburicase as compared to the FDA-approved dose of 0.2 mg/kg intravenously daily for up to five days. Doses in these studies range from 1.5 mg to 7.5 mg. Our study evaluated outcomes in patients who received single 4.5 mg fixed-dose rasburicase. This retrospective, IRB-approved chart review evaluated adult oncology subjects who received fixed-dose rasburicase between January 2007 and April 2014. The primary outcome was percentage of patients with normalization of uric acid (level<8 mg/dL within 24 h) after a single 4.5 mg fixed-dose of rasburicase. Secondary objectives were incidence of initial failure of fixed-dose rasburicase and normalization of uric acid in overweight (body mass index ≥25 kg/m) versus non-overweight patients. Initial failure was defined as need for additional doses or progression to dialysis within one week of the initial fixed-dose. In the 128 patients included, the mean baseline uric acid level was 14.84 mg/dL. Of the 112 patients with a follow-up uric acid level, 68% achieved normalization within 24 h of rasburicase administration. Thirty-eight patients received additional treatment: 10 received additional dose(s) and 28 underwent dialysis. Normalization of uric acid in overweight versus non-overweight patients was 66% and 73%, respectively. Overall, a single 4.5 mg fixed-dose of rasburicase effectively normalized uric acid in 68% of patients within 24 h. Further studies are needed to determine the optimal single fixed-dose necessary for treatment response across all patients.

Despite taking lower MMF doses than previously studied, subjects on a PPI compared to an H2RA were not at increased risk of acute rejection within 1 year posttransplantation.

Our study demonstrates that IVIG is beneficial in patients with medically refractory IBD, and that concomitant CDI is a risk factor for the treatment failure of IVIG for refractory disease.

Objective: To review phase 3 trials of sodium-glucose cotransporter (SGLT) inhibitors in type 1 diabetes mellitus (T1DM) patients. Data Sources: A literature search of Ovid MEDLINE databases (1946 through May 17, 2019) limited to English-language human clinical trials was conducted using the following terms: sodium-glucose transporter 2 inhibitors, canagliflozin, dapagliflozin, empagliflozin, sotagliflozin, ertugliflozin, ipragliflozin, or remogliflozin combined with type 1 diabetes mellitus. Results were verified via Google Scholar and clinicaltrials.gov. Study Selection and Data Extraction: Articles were included if they were phase 3 trials in adults with T1DM. Data Synthesis: Phase 3 trials are available for dapagliflozin, empagliflozin, and sotagliflozin. All 3 drugs demonstrated statistically significant reductions in hemoglobin A1C, weight, and total daily insulin dose without an increased risk of hypoglycemia in up to 52 weeks of therapy. The incidence of diabetic ketoacidosis (DKA) was higher in patients on a SGLT inhibitor at all doses, with the exception of empagliflozin 2.5 mg (0.8% vs 1.2% with placebo). Relevance to Patient Care and Clinical Practice: SGLT inhibitors are potential adjuncts to insulin in T1DM patients, providing clinically meaningful benefits. Regulatory bodies have either approved or are reviewing these agents for use in T1DM. Clinicians should be familiar with the DKA risk associated with SGLT inhibitors and utilize DKA risk-mitigation strategies. Empagliflozin 2.5 mg warrants additional investigation given its efficacy without an increased incidence of DKA. Conclusions: Phase 3 trial data of SGLT inhibitors provide evidence for sustained efficacy in T1DM patients. Appropriate patient selection for therapy and routine monitoring are essential to minimize associated risks.
