RESUMEN
BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) encompasses a spectrum that ranges from simple steatosis to non-alcoholic steatohepatitis (NASH) and to cirrhosis. The recommended treatment for this disease includes measures that target obesity and insulin resistance. The present review summarizes the role of newer anti-diabetic agents in treatment of NAFLD. DATA SOURCES: PubMed, MEDLINE and Ovid databases were searched to identify human studies between January 1990 and January 2013 using specified key words. Original studies that enrolled patients with a diagnosis of NAFLD or NASH and involved use of newer classes of anti-diabetic agents for a duration of at least 3 months were included. RESULTS: Out of the screened articles, four met eligibility criteria and were included in our review. The classes of newer anti-diabetic medications described were dipeptidyl peptidase IV inhibitors and glucagon-like peptide-1 analogues. CONCLUSIONS: Liraglutide and Exenatide showed improvement in transaminases as well as histology in patients with NASH. Sitagliptin showed improvement in transaminases but limited studies are there to access its effect on histology. Further studies are needed to support use of newer anti-diabetic medications in patients with NAFLD.

Social barriers to effective medical care are mandated to be routinely assessed as part of an evaluation for liver transplantation. This study explores how frequently liver transplant programs encounter these barriers in patients undergoing an evaluation and whether programs with higher proportions of Medicaid patients, historically disadvantaged minority patients, and rural patients encounter social barriers more frequently. A survey for assessing patient demographics and social barriers was electronically completed by representatives of 61 of 104 eligible US adult liver transplant programs (59%). Fifty-eight of the 61 programs identified themselves, and their characteristics were similar to those of all 104 US programs according to publicly available data from the Organ Procurement and Transplantation Network. Social barriers were reported to be encountered sometimes (10%-30%) or frequently (>30%) by the 61 programs as follows: inadequate or unstable health insurance (68.9% of the programs), a chaotic social environment (63.9%), a lack of a care partner (60.7%), an inability to obtain transportation (49.2%), a low educational level (36.1%), inadequate housing (23.0%), a language barrier (19.7%), no reliable way of contacting the patient (16.4%), difficulty in obtaining child care (11.5%), and food insecurity (8.2%). The frequencies of perceived social barriers did not differ significantly between programs reporting higher or lower proportions of Medicaid, minority, or rural patients. Our analysis suggests that program-level operational planning for addressing social barriers to transplant listing should be considered regardless of the proportions of Medicaid-insured, racial or ethnic minority, and rural patients in the population.
