Objective To investigate the difference of bone metabolism and its influential factors in patients with psoriasis vulgaris. Methods A total of 229 patients with psoriasis vulgaris were identified as the study group. At the same time, according to age and sex, 229 cases of non-psoriatic healthy people who were conducted physical examination in physical examination center of our hospital were as the control group. Results In males, the serum levels of Ca and P in the psoriasis vulgaris group were lower than those in the non-psoriasis vulgaris group. The levels of Mg, ALP, TG, and LDL-C in male and female psoriasis groups were higher than those of non-psoriasis vulgaris group. The serum 25-OH-D3 in psoriatic group was higher than that in non-psoriasis vulgaris group. BMD of the lumbar spine in male and female and non-psoriasis vulgaris group was slightly higher than that in psoriatic group. BMD of L1, L2, and the lumbar spine in male psoriasis group was lower than that in female psoriasis group, and the mean of lumbar spine was statistically significant. BMD of the right femoral neck and Ward triangle in psoriasis group was slightly higher than that of the left side. According to the psoriasis disease course, osteopenia and osteoporosis mostly occurred in 10-15 years and 5-10 years (28.319% and 27.876%, respectively), followed in 15-20 years group (22.566%). The normal proportion of BMD in male group was higher than that in female group (8.850% in female group and 38.496% in male group). In the same group, the proportion of osteopenia and osteoporosis or fracture in males accounted for 44.585%, and in female group accounted for 72.222%, which was significantly higher than in male group. In the female group, there were 2 cases of fractures (2.778%) in 15-20 years group and over 20 years group. In male psoriasis vulgaris over 20 years group, 1 case of bone fracture occurred (0.637%). Conclusion Bone metabolism level in patients with psoriasis vulgaris is significantly lower than that in normal controls. Education of osteoporosis prevention should begin in the early onset of psoriasis. |
