Randomized trial of steroid free immunosuppression with basiliximab induction in adult live donor liver transplantation (LDLT).

BACKGROUND: Corticosteroids are an integral part of immunosuppression following solid organ transplantation, despite their metabolic complications. We conducted a randomized trial to evaluate the efficacy of steroid-free immunosuppression following live donor liver transplantation (LDLT). METHODS: We randomized 104 patients stratified based on pre-transplant diabetic status to either a steroid-free arm (SF-arm) (Basiliximab + Tacrolimus and Azathioprine,n = 52) or Steroid arm (S-Arm) (Steroid + Tacrolimus + Azathioprine,n = 52). The primary endpoint was the occurrence of metabolic complications (new-onset diabetes after transplant (NODAT), new-onset systemic hypertension after transplant (NOSHT), post-transplant dyslipidemia) within 6 months after transplant. Secondary endpoints included biopsy-proven acute rejection (BPAR) within six months, patient and graft survival at 6 months. RESULTS: The incidence NODAT was significantly higher in S-arm at 3 months (64.5%vs. 28.1%,p-0.004) and 6 months (51.6% vs. 15.6%,p-0.006). Likewise, the incidence of NOSHT (27.8% vs. 4.8%,p-0.01) and hypertriglyceridemia (26.7% vs. 8%,p-0.03) at six months was significantly higher in S-arm. However, there were no differences in BPAR (19.2% vs. 21.2%, p-0.81), time to first rejection (58 vs. 53 days, p-0.78), patient and graft survival (610 vs. 554 days,p- 0.22). CONCLUSION: Following LDLT, basiliximab induction with tacrolimus and azathioprine maintenance resulted in significantly lower metabolic complications compared to the triple-drug regimen of steroid, tacrolimus, and azathioprine.

A randomized, double-blinded, placebo-controlled trial analyzing the effect of synbiotics on infectious complications following living donor liver transplant-PREPRO trial.

BACKGROUND: Following liver transplantation (LT), bacterial infections occur in over 70% of recipients leading to significant morbidity and mortality. While synbiotics have been reported to decrease infectious complications in various surgical procedures, the evidence of their benefits following LT remains limited. METHODS: In this 18-month double-blinded, investigator-initiated, placebo-controlled trial, 100 recipients of live donor liver transplant (LDLT) were randomized to receive either the synbiotic drug Prowel® (Prepro arm) or a placebo, starting 2 days pretransplant and continued for 2 weeks. The primary endpoint was culture-proven bacterial infection in blood, urine or drain fluid within 30 days. Secondary endpoints were hospital stay, noninfectious complications, antibiotic usage and 30-day mortality. RESULTS: Overall infectious complications were significantly lower in the Prepro arm in comparison to the Placebo arm (44% vs 22%, P = .019, OR 0.359; CI: 0.150-0.858). Blood stream infections were significantly less in the study arm (21.7% vs 53.3%, P = .020, OR 0.243; CI: 0.072-0.826), whereas urinary tract and intra-abdominal infections were similar. Length of hospital stay, noninfectious complications, deviation from protocol antibiotics and 30-day mortality were comparable. CONCLUSION: Synbiotics administered for 2 weeks following LDLT significantly reduced overall and blood stream infectious complications in the early postoperative period. However, there was no difference in hospital stay, noninfectious complications, antibiotic usage and mortality. Clinical Trial Registry of India registration number - CTRI/2017/09/009869.
