Abstract (original English)

Lipodystrophy is a rare disease characterized by various metabolic complications resulting from the complete or partial loss of adipose tissues and abnormal fat accumulation. Acquired lipodystrophy may occur due to certain drugs, autoimmunity or for unknown reasons. Recently, cases of acquired lipodystrophy after hematopoietic stem cell transplantation (HSCT) have been reported. Leptin administration, used recently to treat generalized lipodystrophy, effectively controlled metabolic complications; however, few reports demonstrated the effectiveness of leptin for acquired partial lipodystrophy. In this report, we present the case of a 17-year-old woman who developed insulin resistance, hypertriglyceridemia, and fatty liver after HSCT. Due to her thin gluteal fat and low blood adiponectin levels, her metabolic abnormalities were attributed to partial lipodystrophy. While both leptin and pemafibrate administration partially attenuated metabolic abnormalities, its effects were relatively limited, probably because the serum leptin levels were maintained, which is not likely in generalized lipodystrophy. Nevertheless, after she developed adjustment disorder and experienced weight loss, along with decreased food intake, her metabolic markers significantly improved. This case suggests the modest effect of leptin and permafibrate in partial lipodystrophy after HSCT, highlighting the imp
