Secondary hyperparathyroidism (SHPT) is one of the outcomes of vitamin D deficiency that negatively affects bone metabolism. We studied the ethnic differences in vitamin D status in Finland and its effect on serum intact parathyroid hormone (S-iPTH) concentration and bone traits. The study was done in the Helsinki area (60°N) during January–February 2008. A total of 143 healthy women (20–48 years of age) from two groups of immigrant women (Bangladeshi, n 34 and Somali, n 48), and a group of ethnic Finnish women (n 61) were studied in a cross-sectional setting. Serum concentrations of 25-hydroxyvitamin D (S-25OHD) and S-iPTH were measured. Peripheral quantitative computed tomography measurements were taken at 4 and 66 % of the forearm length. In all groups, the distribution of S-25OHD was shifted towards the lower limit of the normal range. A high prevalence of vitamin D insufficiency (S-25OHD < 50 nmol/l) was observed (89·6 %) in the Somali group. The prevalence of SHPT (S-iPTH>65 ng/l) was higher (79·1 %) in Somali women than in Finnish women (16 %). There was a significant association between S-25OHD and S-iPTH (r − 0·49, P < 0·001). Ethnicity and S-25OHD together explained 30 % of the variation in S-iPTH. The total bone mass at all sites of the forearm, fracture load and stress–strain index was higher (P < 0·001) in Bangladeshi and Finnish women than in Somali women. The high prevalence of hypovitaminosis D, SHPT and low bone status in Somali women indicates a higher risk of osteoporosis.

Abstract Introduction: Vitamin D deficiency(VDD) is a common condition in all ages, especially in winter, and causes several adverse outcomes, including cardiovascular diseases. Although there is conflicting information about the causes of cardiac events in VDD, the commonly accepted cause is a pathogenic relationship with hyperparathyroidism.Aim: We aim to demonstrate the effects of hyperparathyroidism, if present, on endothelial and diastolic functions using echocardiography, carotid and brachial tissue Doppler imaging(tDi) in premenopausal women with VDD independent from other confounding risk factors.Methods: Our study is a cross-sectional, observational study investigating premenopausal women aged 18-50 who applied to internal medicine. The patients were divided into two groups according to their parathyroid hormone(PTH) levels. While PTH levels are within the normal range in 41 patients, it was high in 29 patients. Study groups are analyzed for basal characteristics, standard echocardiographic evaluation, carotid, and brachial artery tDi features.Results: There were no significant differences in age, height, weight, body mass index(BMI), and diastolic blood pressures(BP) between the groups(all p values>0.05). Systolic BPs were significantly higher in the secondary hyperparathyroidism, no patients diagnosed with hypertension(Mean systolic BP 124±8, p=0.020). The rate of severe VDD was 78%. In terms of diastolic parameters, prolongation of A wave durations and decreased E/A ratio were observed in the secondary hyperparathyroidism(p values are 0.043 and 0.031, respectively). Carotid and brachial tDi; carotid intima-media thickness(IMT) is significantly higher in secondary hyperparathyroidism(p=0.032).Conclusion: We showed that high PTH levels have adverse effects on diastolic functions(A wave, E/A ratio) and endothelial functions(carotid IMT) in premenopausal women with VDD, even in the absence of other confounding risk factors. We can state that our study's findings will contribute to the literature and are predictive for future studies.

Biologic Function

Major biologic function of activated vitamin D is to maintain normal blood levels of calcium and phosphorus, thus regulating bone mineralization. Research suggests that vitamin D may help in immunomodulation, regulating cell growth and 1,4 differentiation as well as some diverse unspecified functions. Overt vitamin D deficiency leads to hypocalcaemia, secondary hyperparathyroidism and increased bone turnover, which in prolonged and severe cases may cause rickets in children and osteomalacia in elderly....

Background: Vitamin D deficiency is a common medical condition worldwide. In Iran, it has been reported that between 30-90% of people have vitamin D deficiency. However, its distribution in different parts of the country and among different age and regional groups is unclear. Therefore, the aim of this study was to review the recent literature on vitamin D deficiency in Iran. Methods: The literature review was performed using Web of Science, PubMed-Medline, Scopus and Scientific Information Database (SID) with a cut-off date of November 2016 to identify articles on vitamin D status in Iran published in the last 10 years. Studies in English and Persian that reported vitamin D levels in male and female subjects of all age groups and in healthy populations were included. Results: From 325 studies that were initially retrieved, 82 articles met the inclusion criteria. A high prevalence of vitamin D deficiency was reported, and in some regions, this was reported as >90% and was found in all age groups and in all regions of Iran. Conclusion: This review highlights the very high prevalence of vitamin D deficiency in Iran. It will be important to recognize the importance of vitamin D deficiency as a major public health problem in Iran.
