Effect of Dendrobium nobile powder combined with conventional therapy on mild to moderate fatty liver

Nonalcoholic fatty liver disease (NAFLD) encompasses a variety of liver conditions impacting individuals who consume minimal or no alcohol. Recently, traditional Chinese medicine has been gradually used to treat mild to moderate fatty liver, among which Dendrobium nobile Lindl. powder has been affirmed by many doctors and patients to be effective. However, there is limited research on combining this treatment with standard therapies for mild to moderate NAFLD.

To survey the effect of combining Dendrobium nobile Lindl. powder with standard treatment on liver function and lipid metabolism disorder in patients with mild to moderate NAFLD.

Eighty patients with mild to moderate NAFLD participated in this retrospective study, classified into two groups: The observation group (n = 40) and the control group (n = 40). In November 2020 and November 2022, the study was conducted at People's Hospital of Chongqing Liang Jiang New Area. The control group received standard treatment, while the observation group received Dendrobium nobile Lindl. powder based on the control group. The study compared differences in traditional Chinese medicine clinical syndrome scores, liver fibrosis treatment, liver function indicators, lipid levels, and serum inflammatory factor levels before and after treatment, and we calculated the incidence of adverse reactions for both groups.

The total effective rate was 97.50% in the observation group and 72.5% in the control group. After 8 weeks of treatment, the main and secondary symptom scores remarkably decreased, especially in the observation group (P < 0.05), and there was a significant reduction in the serum levels of hyaluronic acid (HA), laminin (LN), human rocollagen III (PC III), and collagen type IV (CIV). The levels of HA, LN, PC III, and CIV were significantly lower in the observation group (P < 0.05). After 8 weeks, both groups indicated remarkable improvements in liver function and blood lipid levels, with the observation group having even lower levels (P < 0.05). Serum levels of interleukin-1β, tumor necrosis factor-α, and interleukin-8 also dropped significantly. The observation group had a lower rate of adverse reactions (5.00%) compared to the control group (22.50%).

Adding Dendrobium nobile Lindl. powder to standard treatment has been found to remarkably improve symptoms and reduce inflammation in patients with mild to moderate fatty liver disease. It also enhances hepatic function and lipid profile, ameliorates liver fibrosis indices, and lowers the risk of side effects. Consequently, this therapeutic protocol shows promise for clinical implementation and dissemination.
