Research Abstract |
We have reported a case of adult growth hormone deficiency (AGHD) accompanied with nonalcoholic steatohepatitis (NASH), in which GH replacement therapy drastically ameliorated NASH. Then, we have analyzed the prevalence of NAFLD/NASH in the patients with AGHD and found that NAFLD/NASH are frequently observed in AGHD and GH replacement therapy improved these conditions. Based on these results, we explored whether GH or IGF-I ameliorates general NASH using animal model. Interestingly, we found that GH particularly IGF-I ameliorated steatosis and fibrosis in the liver of the animal model, implicating a therapeutic application of IGF-I for general NASH.
