Abstract:

Objective

To investigate the effect of paricalcitol combined with ciracalcet on the micro-inflammatory state and alkaline phosphatase (ALP) and parathyroid hormone (iPTH) levels in patients with uremic secondary hyperparathyroidism (SHPT).

Methods

A total of 80 SHPT patients with uremia treated at Yijishan Hospital from June 2019 to December 2020 were selected, and the patients were randomly divided into a combination group (n=40) and a control group (n=40) using the random number table method. The control group was treated with paricalcitol alone, and the combination group was treated with paricalcitol combined with cinacalcet. The treatment lasted for 12 weeks in both groups. The therapeutic effects and the changes in calcium and phosphorus levels, micro-inflammation indicator levels, ALP, iPTH, and parathyroid gland volume between before treatment and 12 weeks after treatment were compared between the two groups.

Results

After 12 weeks of treatment, the total treatment effective rate in the combination group was significantly higher than that of the control group (92.5% vs 75.0%, P<0.05). Blood calcium, blood phosphorus, and calcium phosphorus product in both groups decreased after treatment when compared with the values before treatment (P<0.05 for all), but the decreasing trend was more obvious in the combination group than in the control group (P<0.05 for all). Serum levels of interleukin-6, tumor necrosis factor-α, and C reactive protein (CRP) decreased in both groups when compared with those before treatment (P<0.05 for all), but the decreasing trend was more obvious in the combination group (P<0.05 for all). Serum ALP and iPTH levels were both lower than those before treatment in the two groups (P<0.05 for all), but iPTH was significantly lower in the combination group than in the control group [(326.59±38.39) pg/ml vs (483.21±46.56) pg/ml, P<0.05]. After 12 weeks of treatment, the volume of the parathyroid glands was lower than that before treatment in both groups (P<0.05 for both), and the volume of the parathyroid glands in the combination group was significantly smaller than that of the control group [(0.79±0.14) mm3 vs (1.08±0.19) mm3, P<0.05].

Conclusion

Paricalcitol combined with cinacalcet has a significant therapeutic effect on uremic SHPT, which reduces the micro-inflammatory state of the patients and the levels of ALP and iPTH, as well as the volume of the parathyroid glands.
