Nonalcoholic Steatohepatitis Is the Most Rapidly Growing Indication for Liver Transplantation in Iranian Patients.

OBJECTIVES: Nonalcoholic fatty liver disease is a rapidly growing disease and is hypothesized to become the most common cause of liver cirrhosis in the near future. This study aimed to investigate trends of nonalcoholic steatohepatitis as an indication for liver transplant in Iranian patients. MATERIALS AND METHODS: Liver transplant data from all adult patients (age > 18 y) who had undergone liver transplant between 1993 and 2017 at the Shiraz Organ Transplant Center (Shiraz, Iran) were reviewed. Underlying liver diseases leading to liver transplant were stratified according to year of transplant, and trends of increase or decline were analyzed. Kaplan-Meier curves were used for analysis of posttransplant survival of patients with nonalcoholic steatohepatitis and patients with modified nonalcoholic steatohepatitis. RESULTS: We evaluated 3184 liver transplant patients. Of these, 112 patients with biopsy-proven nonalcoholic steatohepatitis underwent liver transplant up to the end of 2017. Mean age of patients was 52.86 ± 9.01 years in those with nonalcoholic steatohepatitis and 51.73 ± 7.91 years in those with modified nonalcoholic steatohepatitis (P > .05).The prevalence of nonalcoholic steatohepatitis as an indication for liver transplant was 0.8% in 2011, 0.36% in 2012, 1.9% in 2013, 4.01% in 2014, 2.89% in 2015, 6.65% in 2016, and 9.97% in 2017. The prevalence of modified nonalcoholic steatohepatitis was 2.4% in 2011, 2.88% in 2012, 2.71% in 2013, 2% in 2014, 2.17% in 2015, 2.13% in 2016, and 2.28% in 2017. We found that nonalcoholic steatohepatitis as a cause of liver transplant increased significantly during recent years (P < .001). CONCLUSIONS: Nonalcoholic steatohepatitis is a rapidly growing indication for liver transplant among Iranian patients. Health care providers should consider programs for prevention and early diagnosis of patients with nonalcoholic steatohepatitis for proper treatment.

Liver Transplant for Primary Hyperoxaluria Type 1: Results of Sequential, Combined Liver and Kidney, and Preemptive Liver Transplant.

OBJECTIVES: Primary hyperoxaluria type 1 is an autosomal recessive disorder that causes overproduction and urinary excretion of oxalate. Liver transplant has been suggested as a treatment for primary hyperoxaluria type 1 since the defective enzyme is expressed in the liver. This study aimed to investigate results of combined liver and kidney, sequential, and preemptive livertransplantin patients with primary hyperoxaluria type 1. MATERIALS AND METHODS: In this cohort study, we followed patients with primary hyperoxaluria type 1 who underwent liver transplant at our centerin Shiraz, Iran. Clinical and laboratory data of patients were gathered, and major outcomes, including renal failure after liver transplant, rejection, and mortality were recorded. Survival of patients was analyzed by the Kaplan-Meier method. RESULTS: Our study included 24 patients. There were 16 male (66.6%) and 8 female (33.33%) patients. Thirteen patients were in the pediatric age group (age < 18 y), and 11 patients were adults (age ≥ 18 y). Thirteen patients underwent sequential transplant, 8 patients underwent combined liver and kidney transplant, and 3 patients underwent preemptive transplant. All patients received organs from deceased donors. There were no statistically significant differences in mortality, rejection, and hemodialysis after transplant between those with sequential transplant and those with combined liver and kidney transplant (P > .05). CONCLUSIONS: Liver transplant can be considered a treatment for patients with primary hyperoxaluria type 1. Combined liver and kidney transplant and preemptive liver transplant could be proper options for these patients.
