Review
Chronic kidney disease (CKD) induces mineral and bone disorders (CKD-MBD) that affect calcium and phosphate metabolism. This review links pathophysiology, histologic aspects, and radiologic signs. CKD leads to bone lesions, namely renal osteodystrophy, which may combine low or high bone remodeling, impaired mineralization, and bone loss. CKD-MBD also comprises vascular calcifications, which, together with bone disease, lead to a high risk of cardiovascular events and osteoporotic fractures that increase both morbidity and mortality. Osteoporosis assessment is based on screening for classic risk factors and CKD-related factors (disease duration/severity, transplantation history, dialysis vintage). Treatment of mineral disorders may combine serum phosphate lowering drugs, natural vitamin D or its 1-α derivatives, or calcium-sensing receptor agonists. Treatment of osteoporosis is conventional in mild to moderate stages but more complex in severe CKD because evidence about the efficacy and safety of anti-osteoporosis drugs is scant.

La Tunisie Medicale Dec 2023Vitamin D plays a role in regulating the immune response through an immunomodulatory effect, and is probably involved in the pathophysiology of Crohn's disease (CD).
INTRODUCTION
Vitamin D plays a role in regulating the immune response through an immunomodulatory effect, and is probably involved in the pathophysiology of Crohn's disease (CD).
AIM
to assess vitamin D status in patients with CD as well as in healthy controls and to determine associated factors of vitamin D deficiency in patients with CD.
METHODS
We conducted a prospective study over 18 months, including CD patients with age and sex matched with healthy controls. Suboptimal vitamin D status was defined by vitamin D serum level < 30 ng/ml, vitamin insufficiency by vitamin D serum level between 10 and 30 ng/ml and vitamin deficiency serum level < 10 ng/ml.
RESULTS
We included 77 subjects (52 patients with CD and 25 controls) with mean age of 38 years± 11. Most patients and controls had suboptimal levels of vitamin D (98% and 96% respectively) including vitamin D deficiency in 75% and 67%, respectively and vitamin D insufficiency in 25% and 33%, respectively. In univariate analysis, vitamin D deficiency was associated with disease flare-up (p=0.001), anemia (p=0.002), hypo-albuminemia (p=0.002), elevated C-reactive protein (CRP) (p=0.003), Crohn's Disease Activity Index (CDAI) (p<0.001), ileal location (p=0.04) and immunosuppressive therapy (p=0.01). In multivariate analysis, only CDAI was significantly associated with vitamin D deficiency (p=0.003, OR=9.33).
CONCLUSION
Vitamin D deficiency is common in Tunisian CD patients as well as in controls and is associated with disease activity.

Review
Menopause is the transition period in female life cycle. Resultant hormonal changes lead to adverse health effects. Women may seek treatment due to significant impairment in quality of life. Vitamin D deficiency is a globally prevalent problem. Vitamin D deficiency in menopausal women may aggravate the adverse health risks associated with menopause. In this article, the authors discuss endocrinology and clinical features of menopause, Vitamin D and its links with menopause, and the potential role of Vitamin D supplementation to combat detrimental multi-organ system effects of menopause.

Review
Hashimoto's thyroiditis (HT) is marked by self-tissue destruction as a consequence of an alteration in the adaptive immune response that entails the evasion of immune regulation. Vitamin D carries out an immunomodulatory role that appears to promote immune tolerance. The aim of this study is to elaborate a narrative review of the relationship between vitamin D status and HT and the role of vitamin D supplementation in reducing HT risk by modulating the immune system. There is extensive literature confirming that vitamin D levels are significantly lower in HT patients compared to healthy people. On the other hand, after the supplementation with cholecalciferol in patients with HT and vitamin D deficiency, thyroid autoantibody titers decreased significantly. Further knowledge of the beneficial effects of vitamin D in the prevention and treatment of autoimmune thyroid diseases requires the execution of additional randomized, double-blind, placebo-controlled trials and longer follow-up periods.

BACKGROUND
Depression is an important public health burden, its risk of occurrence is associated with vitamin D deficiency and may also increase with age, while serum vitamin D levels are closely related to age.
OBJECTIVE
The purpose of this study was to evaluate whether vitamin D and age are associated with depression after adjustment for each other.
MATERIALS AND METHODS
We extracted data from NHANES 2013-2018, including demographic characteristics, depression level, vitamin D level, physical activity, and body measures. A total of 15,156 adults aged 20 years or older (mean age 49.81 ± 17.67 years, 7301 males and 7855 females) were included. Depression was screened by PHQ-9. Vitamin D deficiency was defined by a serum vitamin D level < 30nmol/L. We performed binary logistic regression models to analyze the association between vitamin D, age and depression, respectively.
RESULTS
Vitamin D levels were negatively associated with depression (P < 0.001). Vitamin D had a significant effect on depression (OR = 0.776, 95%CI: 0.682-0.884, P < 0.001), the effect remained significant after adjusted for confounding variables (OR = 0.761, 95%CI: 0.663-0.874, P < 0.001). Age was positively associated with depression (P < 0.001) and had a significant effect on depression (OR = 1.079, 98%CI: 1.032-1.128, P = 0.001), the effect remained significant after adjusted for confounding variables (OR = 1.092, 95%CI: 1.040-1.146, P < 0.001). Age and vitamin D levels were positively correlated (P < 0.001), and older age had a significant effect on vitamin D level (OR = 1.526, 95%CI: 1.416-1.645, P < 0.001), the effect remained significant after adjusted for confounding variables (OR = 1.371, 95%CI: 1.263-1.487, P < 0.001). In addition, the prevalence of depression was higher in females (2312/7855, 29.43%) than in males (1571/7301, 21.52%), and the difference was statistically significant (P < 0.001).
CONCLUSIONS
Vitamin D deficiency and older age are both associated with higher risk of depression, while older age is a protective factor for vitamin D deficiency.

Maternal vitamin D deficiency, which is highly prevalent in pregnant women in Europe, is linked to adverse health effects for both the mother and child. The objective was to assess vitamin D status in pregnant women by evaluating their dietary and supplemental vitamin D intake, serum vitamin D levels, parathyroid hormone levels, and lifestyle factors. This cross-sectional study, with a total of 735 participants (145 pregnant and 590 up to the seventh day postpartum), took place in Latvia. Blood samples, a food frequency questionnaire, and medical documentation were used for data collection. The median serum vitamin D concentration was 34.0 ng/mL, with pregnant women having higher levels (42.9 ng/mL) than postpartum women (31.8 ng/mL). There was no association between vitamin D serum concentration and dietary intake of vitamin D ( > 0.05), whereas there was a significant correlation with use of vitamin D supplements (r = 0.41; < 0.001 in pregnant women and r = 0.35; < 0.001 in postpartum women). This study demonstrated that a minority of pregnant women (21.9%) had optimal serum vitamin D concentration (>45 ng/mL), and diet had no significant impact on vitamin D levels. Thus, our proposed recommendation for vitamin D intake during pregnancy was 63 mcg (2500 IU) year-round for optimal levels in pregnant women in Northeastern Europe.

Review
Osteoporosis (OP) and Dermatoporosis (DP) are expressions of the aging process at the skin and bone levels, respectively. Both conditions are associated with increased morbidity for elderly people, and this requires necessary interventions. They share many common risk factors; among these, vitamin D (VD) deficiency appears to have a role. VD is involved in either disease with many mechanisms, among which immunomodulation. VD deficiency has been linked to OP because it inhibits the body's capacity to absorb calcium and maintain optimal bone health. Available evidence suggests that proper vitaminosis D also appears to be vital in preventing skin age-related issues. DP is often seen in elderly individuals, particularly those with long-term sun exposure and a history of chronic sun damage. VD deficiency can be linked to DP, since its involvement in collagen production, epidermal barrier function, inflammation regulation, wound healing, and sun protection. Aim of this review is to summarize the most updated existing evidence on the role of VD in the development of fragility syndromes such as DP and OP and the possible benefits of VD supplementation as a simple and harmful weapon against aging.

Hypovitaminosis D has been associated with worse outcome in respiratory tract infections, with conflicting opinions regarding its role in Coronavirus-19 disease (COVID-19). Our study aimed to evaluate the possible relationship between 25-OH vitamin D (25OHD) values and the following conditions in patients hospitalized for COVID-19: prognosis, mortality, invasive (IV) and non-invasive (NIV) mechanical ventilation, and orotracheal intubation (OTI). A further objective was the analysis of a possible positive effect of supplementation with calcifediol on COVID-19 severity and prognosis. We analyzed 288 patients hospitalized at the San Giovanni di Dio Hospital in Florence and the Santa Maria alle Scotte Hospital in Siena, from November 2020 to February 2021. The 25OHD levels correlated positively with the partial pressure of oxygen and FiO2 (PaO2/FiO2) ratio (r = 0.17; < 0.05). Furthermore, when we analyzed the patients according to the type of respiratory support, we found that 25OHD levels were markedly reduced in patients who underwent non-invasive ventilation and orotracheal intubation (OTI). The evaluation of the length of hospitalization in our population evidenced a longer duration of hospitalization in patients with severe 25OHD deficiency (<10 ng/mL). Moreover, we found a statistically significant difference in the mortality rate between patients who had 25OHD levels below 10 ng/mL and those with levels above this threshold in the total population (50.8% vs. 25.5%, = 0.005), as well as between patients with 25OHD levels below 20 ng/mL and those with levels above that threshold (38.4% vs. 24.6%, = 0.04). Moreover, COVID-19 patients supplemented with calcifediol presented a significantly reduced length of hospitalization ( < 0.05). Interestingly, when we analyzed the possible effects of calcifediol on mortality rate in patients with COVID-19, we found that the percentage of deaths was significantly higher in patients who did not receive any supplementation than in those who were treated with calcifediol ( < 0.05) In conclusion, we have demonstrated with our study the best prognosis of COVID-19 patients with adequate vitamin D levels and patients treated with calcifediol supplementation.
