Objectives:
To investigate the cross-sectional and longitudinal correlation between sex hormones and non-alcoholic fatty liver disease (NAFLD) in patients with obesity before and after laparoscopic sleeve gastrectomy (LSG).
Methods:
A total of 360 patients with obesity aged 16-48 years (170 men and 190 women) were enrolled between May 2017 and March 2021. Among them, 132 patients (55 men and 77 women) who underwent LSG had follow-up data. Anthropometric parameters, metabolic variables, and sex hormones were measured. NAFLD was assessed by FibroScan with controlled attenuation parameter (CAP) and liver stiffness measurement (LSM).
Results:
In the preoperative cohort, levels of CAP and LSM were significantly higher in men than women. Lower total testosterone (TT) was associated with higher CAP and LSM in men, whereas higher TT was associated with higher CAP in women. In the postoperative cohort, TT levels and NAFLD were significantly modified after LSG in both genders. Changes in TT levels at 3 months after surgery were negatively correlated with changes in CAP levels in men, and changes in TT levels at 6 months after surgery were positively correlated with changes in CAP levels in women. After adjusting possible confounders, the changes in TT levels were independently correlated with CAP variation in both genders.
Conclusions:
LSG significantly modified TT levels and NAFLD in both genders. The correlation between TT levels and NAFLD at baseline as well as the changes after surgery suggested TT levels play an important role in the development and regression of NAFLD in both genders.
