[Comparison of the clinical effects between Dihuang Decoction and alendronate sodium in the treatment of primary osteoporosis].

Objective: To study and compare the clinical effects of Rehmannia Decoction and alendronate sodium for the treatment of primary osteoporosis.

Methods: From January 2016 to December 2017, 72 patients with primary osteoporosis who took Dihuang Decoction(DHD) orally and alendronate regularly for more than one year were randomly divided into 2 groups:experimental group and control group. The experimental group consisted of 14 males and 22 females, with an average age of(63.97±3.70) years old. The patients in the experimental group took Chinese medicine DHD, one dose each time, one time in the morning and one time in the evening, twice a week. The control group consisted of 16 males and 20 females with an average age of(63.36±3.07) years old. Patients in the control group were given alendronate 70 mg orally once a week. The basic treatment for osteoporosis remained unchanged in both groups(600 mg of calcium carbonate D3 and 0.5 μg of calcitriol capsules were taken daily). Bone mineral density (BMD) of femoral neck and lumbar vertebrae was measured by dual energy X-ray absorptiometry before and after treatment for one year. The levels of serum collagen type I C-terminal peptide (beta-CTX) and serum osteoclast (SOST) were measured before and after treatment for two groups.

Results: The age, bone mineral density, SOST and beta-CTX baseline values between the two groups before and after anti-osteoporosis treatment were compared. The difference was not statistically significant(>0.05). Compared with the two groups, the BMD of femoral neck and lumbar vertebrae were increased after 1 year of anti-osteoporosis treatment. The differences were statistically significant (<0.001). The value of serum beta-CTX was significantly lower than before. The values were 52.002 and 50.071 respectively. The value of serum SOST was increased than that before treatment. The values were -29.242 and -30.807 respectively. The differences were statistically significant (<0.001). BMD of the femoral neck and lumbar spine was compared between the two groups after treatment. The P values were 0.294 and 0.478 respectively. The difference was not statistically significant (>0.05). The serum beta-CTX values were compared between the two groups after treatment. The value was 0.908. The serum SOST values were compared between the two groups after treatment. The value was 0.888. The difference was not statistically significant (>0.05).

Conclusions: In this study, traditional Chinese medicine DHD is used to treat osteoporosis. It is found that DHD and alendronate have a good effect. The DHD can be used as a choice of Chinese medicine in the treatment of primary osteoporosis.
