Efecto de las terapias incretínicas comparadas con pioglitazona y gliclazida en la esteatosis hepática no alcohólica de los pacientes diabéticos no controlados solo con metformina: estudio observacional piloto / Effect of incretin therapies compared to pioglitazone and gliclazide in non-alcoholic fatty liver disease in diabetic patients not controlled on metformin alone: An observational, pilot study

Objetivo: Comparar el efecto de diferentes hipoglucemiantes en indicadores analíticos y ecográficos de la esteatosis hepática no alcohólica (EHNA) en pacientes con diabetes tipo 2 no controlados solo con metformina. Métodos: Estudio prospectivo de pacientes diabéticos tratados con metformina, en combinación con gliclazida, pioglitazona, sitagliptina, exenatida o liraglutida. En el momento basal y a los 6 meses la EHNA fue valorada por ecografía abdominal y se calculó el índice de fibrosis de la EHNA. Resultados: Cincuenta y ocho pacientes completaron los 6 meses de seguimiento: 15 recibieron gliclazida, 13 pioglitazona, 15 sitagliptina, 7 exenatida y 8 liraglutida. La EHNA afectó basalmente al 57,8% de los casos y su evolución ecográfica varió dependiendo de la evolución del peso (p = 0,009) y de la cintura (p = 0,012). Los porcentajes de sujetos que experimentaron una mejoría ecográfica en los diferentes grupos de tratamiento fueron: 33,3% con gliclazida, 37,5% con pioglitazona, 45,5% con sitagliptina, 80% con exenatida y 33% con liraglutida (p = 0,28). Conclusiones: La evolución ecográfica cualitativa de la EHNA en el paciente diabético tratado con metformina en combinación con otros hipoglucemiantes está vinculada a la evolución del peso y del perímetro de cintura. Son precisos ensayos clínicos de larga duración para evaluar si las terapias incretínicas se asocian a mejores resultados hepáticos que otras terapias hipoglucemiantes (AU)

Aim: To compare the effect of different hypoglycemic drugs on laboratory and ultrasonographic markers of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes not controlled on metformin alone. Methods: Prospective study of diabetic patients treated with metformin in combination with gliclazide, pioglitazone, sitagliptin, exenatide, or liraglutide. NAFLD was assessed by abdominal ultrasound and NAFLD fibrosis score was calculated at baseline and 6 months. Results: Fifty-eight patients completed 6 months of follow-up: 15 received gliclazide, 13 pioglitazone, 15 sitagliptin, 7 exenatide, and 8 liraglutide. NAFLD affected 57.8% of patients at baseline, and its ultrasonographic course varied depending on changes in weight (P = .009) and waist circumference (P = .012). The proportions of patients who experienced ultrasonographic improvement in the different treatment groups were: 33.3% with gliclazide, 37.5% with pioglitazone, 45.5% with sitagliptin, 80% with exenatide, and 33% with liraglutide (P = .28). Conclusions: Qualitative ultrasonographic NAFLD improvement in diabetic patients treated with metformin in combination with other hypoglycemic drugs is associated to change over time in weight and waist circumference. Long-term clinical trials are needed to assess whether incretin therapies result in better liver outcomes than other hypoglycemic therapies (AU)
