Abstract:

Purpose: The aim was to determine the relationship between serum vitamin D levels and urine calcium output in individuals with vitamin D deficiency. Tools and methods: 400 volunteers between the ages of 30-50 were included in the study. Full blood count with demographic data of patients, serum 25-OH vitamin D, parathormone (PTH), calcium, albumin, phosphorus, thyroid stimulating hormone (TSH), magnesium, lipid profile (total cholesterol, triglyceride, LDL, HDL), alkaline phosphate, creatine and urine calcium, creatine levels were decimated. Results: 265 of the 319 cases studied were in the vitamin D deficiency group, 54 were in the control group (vitamin D at normal levels). The parathormon values are statistically significantly high in the vitamin D deficiency group compared to the control group, while the calcium values are statistically significantly low in the control group compared to the vitamin D deficiency group. The ratio of calcium/creatine in the spot urine was an average of 0.08 ± 0.06 in the vitamin D deficiency group and 0.09 ± 0.07 in the control group (p=0.197). There is no statistically significant difference in the ratio of calcium/creatin in the spot urine between the groups. The result: in our study, vitamin D deficiency was detected in cases where calcium output in the urine was a bit reduced according to the control group, but statistically no significant difference was detected. There is also no correlation between the levels of vitamin D and calcium in the urine. Our findings do not provide sufficient evidence that the calcium values measured in the spot urine can be a useful indicator in the detection of vitamin D deficiency, and it requires more detailed studies on this.
