Abstract Context Recent findings have suggested a high prevalence of vitamin D deficiency or insufficiency in fibromyalgia (FM) patients despite the lack of clinical and pathophysiological evidence. Objective A systematic review was conducted to examine the association between vitamin D status and FM, including the effect of vitamin D supplementation. Data source PubMed, LILACS, Scopus, SciELO, Cochrane, and EMBASE were searched, from January 2000 to July 2018, using the descriptors “Fibromyalgia” and “Vitamin D.” Study selection Trials including FM patients in whom vitamin D levels were assessed were eligible for inclusion. Data extraction Data comprised age, gender, country, aims, bias, diagnosis criteria, cutoff point, and status of vitamin D, together with FM symptoms and vitamin D supplementation protocol. Results A total of 26 articles were selected. Most of the studies were found to present unreliable control groups and small samples. Experimental data on vitamin D supplementation indicated improvement in certain FM symptoms. Conclusion Prevalence of hypovitaminosis D in the FM population and the cause-effect relationship were inconclusive. Nevertheless, vitamin D supplementation may be considered as a co-adjuvant in FM therapy.

Vitamin D Levels

Vitamin D is a lipid soluble vitamin involved primarily in calcium metabolism. Epidemiologic evidence indicates that lower circulating vitamin D levels are associated with a higher risk of ovarian cancer and that vitamin D supplementation is associated with decreased cancer mortality. A vast amount of research exists on the possible molecular mechanisms through which vitamin D affects cancer cell proliferation, cancer progression, angiogenesis, and inflammation. We conducted a systematic review of the literature on the effects of vitamin D on ovarian cancer cell.

Vitamin D may play a significant role in regulating the rate of aging. The objective of the study was to assess vitamin D status and its associated factors in institutionalized elderly individuals. A total of 153 elderly individuals living in Nursing Homes (NH) were recruited into the study. Serum 25-hydroxyvitamin D [25(OH)D] concentration was used as the biomarker of vitamin D status, and it was considered as the dependent variable in the model. The independent variables were the type of NH, age-adjusted time of institutionalization, age, sex, skin color, body mass index, waist and calf circumference, physical activity practice, mobility, dietary intake of vitamin D and calcium, vitamin D supplementation, use of antiepileptics, and season of the year. Serum 25(OH)D concentrations less than or equal to 29 ng/mL were classified as insufficient vitamin D status. The prevalences of inadequate dietary intake of vitamin D and calcium were 95.4% and 79.7%, respectively. The prevalence of hypovitaminosis D was 71.2%, and the mean serum concentration of 25(OH)D was 23.9 ng/mL (95% confidence interval [CI]: 22.8–26.1). Serum 25(OH)D concentration was associated with the season of summer (p = 0.046). There were no associations with other independent variables (all p > 0.05). The present results showed that a high prevalence of hypovitaminosis D was significantly associated with summer in institutionalized elderly individuals.

OBJECTIVEVitamin D deficiency has been associated with a variety of negative outcomes in critically ill patients, but little focused study on the effects of hypovitaminosis D has been performed in the neurocritical care population. In this study, the authors examined the effect of vitamin D deficiency on 3-month outcomes after discharge from a neurocritical care unit (NCCU).METHODSThe authors prospectively analyzed 25-hydroxy vitamin D levels in patients admitted to the NCCU of a quaternary care center over a 6-month period. Glasgow Outcome Scale (GOS) scores were used to evaluate their 3-month outcome, and univariate and multivariate logistic regression was used to evaluate the effects of vitamin D deficiency.RESULTSFour hundred ninety-seven patients met the inclusion criteria. In the binomial logistic regression model, patients without vitamin D deficiency (> 20 ng/dl) were significantly more likely to have a 3-month GOS score of 4 or 5 than those who were vitamin D deficient (OR 1.768 [95% CI 1.095–2.852]). Patients with a higher Simplified Acute Physiology Score (SAPS II) (OR 0.925 [95% CI 0.910–0.940]) and those admitted for stroke (OR 0.409 [95% CI 0.209–0.803]) or those with an “other” diagnosis (OR 0.409 [95% CI 0.217–0.772]) were significantly more likely to have a 3-month GOS score of 3 or less.CONCLUSIONSVitamin D deficiency is associated with worse 3-month postdischarge GOS scores in patients admitted to an NCCU. Additional study is needed to determine the role of vitamin D supplementation in the NCCU population.

Vitamin D deficiency is one of the most common medical conditions worldwide. In Tunisia, several studies evaluated Vitamin D status, but this was concerning specific populations (pregnant women, obese or diabetic patients and children with asthma). The only study that evaluated Vitamin D status in a healthy Tunisian population was conducted by Meddeb and al. in 2002. The update of data available, based on the currently recommended limits, is necessary. This study aimed to estimate the prevalence of hypovitaminosis D in a healthy Tunisian population, and correlate the values with potential risk factors. It was conducted on 209 Tunisian healthy subjects. Data collected included clinical characteristics and dietary intakes. We measured 25-hydroxyvitamin D (25(OH)D), parathyroid hormone (PTH), glycemia, creatinine, calcium, phosphorus, proteins and alkaline phosphatase levels. Hypovitaminosis D was retained for 25(OH)D concentrations <30ng/ml. Vitamin D deficiency was defined by 25(OH)D concentrations <10 ng/ml. The prevalence of hypovitaminosis D and vitamin D deficiency were respectively 92.3% and 47.6%. The main factors that were significantly associated with low vitamin D levels in our multivariate analysis were veiling, living in rural areas and sunscreen use. However, sex, age, socioeconomic level, phototype, solar exposure score, smoking and bone mass index, were not statistically associated with hypovitaminosis D. The study of relationship between vitamin D status and serum PTH levels showed a significative and negative correlation (p< 0.005). Given the high prevalence of vitamin D, an adapted health policy is essential. A widespread vitamin D supplementation and food fortification seems to be necessary in Tunisia.

Adequate vitamin D levels are particularly important in pregnant women for both the maternal and neonatal health. Prior studies have shown a significantly high prevalence of vitamin D deficiency (VDD) among refugees. However, no study has addressed the prevalence of VDD in pregnant refugees and its effects on neonatal health. In this study, we examined the prevalence of VDD in refugee pregnant women living in Greece and compared our results with Greek pregnant inhabitants. Vitamin D deficiency was frequent in both groups but was significantly more common in refugees (92.2% vs 67.3% of Greek women, p=0.003) with 70.6% of refugees having severe hypovitaminosis D (<10 ng/ml). As a result, most newborns had Vitamin D deficiency, which affected refugee newborns to a greater extent. Our results suggest a need to screen newcomer children and pregnant women for vitamin D deficiency in all host countries around the world. Such a screen will appropriately guide early and effective interventions with the goal to prevent adverse neonatal and maternal outcomes.

Abstract Purpose: Concomitant vitamin D deficiency (VDD) is speculated to aggravate diabetic macular edema (DME). We aimed to determine the effect of hypovitaminosis D correction on the outcome of treatment with intravitreal bevacizumab (IVB) in DME eyes.Methods: 83 eyes of 83 patients with DME were recruited and divided into three groups: normal vitamin D levels + IVB administration (Group 1 ), vitamin D insufficient/deficient + IVB administration (Group 2), and vitamin D insufficient/deficient + IVB administration+ oral vitamin D supplementation (Group 3). Visual (corrected distance visual acuity, CDVA) and anatomical (central macular thickness, CMT) outcomes of intervention were evaluated 1, 3, and 6 months after the triple IVB injections were completed. Serum vitamin D levels were measured 1 and 6 months after the third IVB administration. Results: In months 1, 3, and 6, after the basic triple IVB injection, visual acuity and CMT improved in all three groups, but improvements (both functional and anatomical) in groups 1 and 3 (sufficient vitamin D and corrected hypovitaminosis D) in month 6 were more significant than in group 2 (uncorrected hypovitaminosis D) (p <0.001). The mean number of IVB injections during follow-up was 5.33 (range: 4-7), which did not differ between the groups.Conclusion: Correction of vitamin D deficiency in DME patients with type 2 diabetes and vitamin D deficiency, in addition to IVB injections, may play a role in improving CDVA and CMT. However, this beneficial effect seems to be delayed by several months.Trial registration: Iranian Registry of Clinical Trials (IRCT), IRCT20200407046978N1, registered on April 11, 2020, - retrospectively registered. https://en.irct.ir/trial/46999

The concept that extra-skeletal functions of vitamin D impact on human health have taken place since quite ago. Among all, the beneficial effects of vitamin D on immune regulation, skeletal muscle function, and metabolism are undeniable. Adequate vitamin D levels maintain the immune system and skeletal muscle metabolism integrity, promoting whole-body homeostasis; hypovitaminosis D associates with the important decline of both tissues and promotes chronic inflammation, which is recognized to underlie several disease developments. Growing evidence shows that the immune system and skeletal muscle reciprocally dialogue, modulating each other’s function. Within this crosstalk, vitamin D seems able to integrate and converge some biomolecular signaling towards anti-inflammatory protective effects. Thus, vitamin D regulation appears even more critical at the immune system-muscle signaling intersection, rather than at the single tissue level, opening to wider/newer opportunities in clinical applications to improve health. This paper aims to focus on the immune system-skeletal muscle interplay as a multifaceted target for vitamin D in health and disease after recalling the main regulatory functions of vitamin D on those systems, separately. Some myokines, particularly relevant within the immune system/skeletal muscle/vitamin D networking, are discussed. Since vitamin D supplementation potentially offers the opportunity to maintain health, comments on this issue, still under debate, are included.

<p class="abstract"><strong>Background:</strong> There is an alarmingly high prevalence of hypovitaminosis D in orthopaedic patients, regardless of whether or not, they require surgical intervention. Vitamin D plays an essential role in bone formation, maintenance, and remodelling, as well as muscle function and deficiency could affect adversely in multiple ways. Many reports recently demonstrated high rates of vitamin D deficiency, in numerous segments of Indian population, but there is no study reported so far from India, which focuses specifically on vitamin D status in orthopaedic patients.</p><p class="abstract"><strong>Methods:</strong> It is a descriptive study to<strong> </strong>estimate vitamin D levels in patients scheduled to undergo orthopaedic surgery. Vitamin D, calcium, phosphorus and alkaline phosphatase (ALP) levels in 310 patients, who were admitted at our institution, from December 2015 to August 2017 were measured.<strong></strong></p><p class="abstract"><strong>Results:</strong> Out of 310 patients included in our study, 189 (61%) were males and 121 (39%) females. Vitamin D deficiency (&lt;20 ng/ml) was present in 232 patients, insufficiency (&lt;30 ng/ml) was present in 63 patients and only 15 patients had desirable levels (&gt;30 ng/ml). Patients younger than 60 years and males had more prevalence of Vitamin D abnormality. 168 (72.4%) of the patients, with deficiency presented in winter, compared to 64 (27.6%) in summer.</p><p class="abstract"><strong>Conclusions:</strong> Statistically significant vitamin D deficiency was seen during winter months, in patients undergoing hip hemiarthroplasty, and in patients admitted for degenerative disease of the spine, hip and knee. Screening and treating hypovitaminosis D appears to be important in orthopaedic patients as vitamin D deficiency is prevalent across all age groups in the population studied.</p>
