Structured abstractImportanceVitamin D deficiency increases the incidence of respiratory virus infections. More than 1 billion people worldwide are vitamin D deficient. If vitamin D deficiency is associated to incidence or severity of SARS-CoV-2 infection, a global call could be made for vitamin D supplementation to mitigate the pandemic.Objectiveto determine if lower serum 25-hydroxyvitamin D (25(OH)D) levels are correlated to the risk for COVID-19 and its severity as measured by CTDesignsingle-center observational studySettingAZ Delta general hospitalParticipants186 consecutive patients with PCR-confirmed SARS-CoV-2 infection hospitalized for COVID-19 from March 1, 2020 to April 7, 2020Main outcome and measurescomparative analysis of 25(OH)D levels in patients hospitalized for COVID-19 at various radiological stages and a season/age/sex-matched diseased control populationResultswe report on 186 SARS-CoV-2 infected patients requiring hospitalization for severe COVID-19: 109 males (median age 68 years, IQR 53–79 years) and 77 females (median age 71 years, IQR 65–74 years). At admission patients were screened by CT to determine temporal changes of COVID-19 lung disease and classified as stage 1 (ground glass opacities), 2 (crazy paving pattern) and 3 (consolidation). At intake, 25(OH)D levels were measured and compared to a season-matched population of 2717 diseased controls, consisting of 999 males (median age 69 years, IQR 53–81 years) and 1718 females (median age 68 years, IQR 43–83 years). Male and female COVID-19 patients combined showed lower median 25(OH)D than controls (18.6 ng/mL, IQR 12.6–25.3, versus 21.5 ng/mL, IQR 13.9–30.8; P=0.0016) and a higher fraction of vitamin D deficiency (58.6% versus 45.2%, P=0.0005). A strong sexual dimorphism was found: female patients had comparable vitamin D status as control females. Male COVID-19 patients, however, showed markedly higher percentage of vitamin D deficiency than controls (67.0% versus 49.2%, P=0.0006) and this effect was more pronounced with advanced radiological stage ranging from 55.2% in stage 1 to 74% in stage 3.Conclusions and relevancevitamin D deficiency is a possible risk factor for severe SARS-CoV-2 infection in males. Vitamin D supplementation might be an inexpensive, accessible and safe mitigation for the SARS-CoV-2 pandemic.Key pointsQuestion: does vitamin D deficiency predispose to severity of SARS-CoV-2 infection?Findings: in this observational study on 186 consecutive patients hospitalized with PCR-confirmed SARS-CoV-2 infection, we find that patients with severe COVID-19 show lower median serum 25(OH)D and a higher percentage of vitamin D deficiency at intake than a season/age-matched reference population. The correlation between vitamin D deficiency and the need for hospitalization due to COVID-19 was only seen in male patients. In males but not females, the percentage of vitamin D deficient patients also increased with more advanced COVID-19 disease stage as measured by CT.Meaning: our data indicate a strong statistical correlation between the degree of vitamin D deficiency and severity of COVID-19 lung disease. With more than 1 billion people worldwide affected by vitamin D deficiency, vitamin D supplementation might be a lifesaving, inexpensive, accessible and safe component of primary prevention during the SARS-CoV-2 pandemic and beyond

Abstract Objectives Vitamin D deficiency was previously correlated with incidence and severity of coronavirus disease 2019 (COVID-19). We investigated the association between serum 25-hydroxyvitamin D (25(OH)D) level on admission and radiologic stage and outcome of COVID-19 pneumonia. Methods A retrospective observational trial was done on 186 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)–infected individuals hospitalized from March 1, 2020, to April 7, 2020, with combined chest computed tomography (CT) and 25(OH)D measurement on admission. Multivariate regression analysis was performed to study if vitamin D deficiency (25(OH)D <20 ng/mL) correlates with survival independently of confounding comorbidities. Results Of the patients with COVID-19, 59% were vitamin D deficient on admission: 47% of females and 67% of males. In particular, male patients with COVID-19 showed progressively lower 25(OH)D with advancing radiologic stage, with deficiency rates increasing from 55% in stage 1 to 74% in stage 3. Vitamin D deficiency on admission was not confounded by age, ethnicity, chronic lung disease, coronary artery disease/hypertension, or diabetes and was associated with mortality (odds ratio [OR], 3.87; 95% confidence interval [CI], 1.30-11.55), independent of age (OR, 1.09; 95% CI, 1.03-1.14), chronic lung disease (OR, 3.61; 95% CI, 1.18-11.09), and extent of lung damage expressed by chest CT severity score (OR, 1.12; 95% CI, 1.01-1.25). Conclusions Low 25(OH)D levels on admission are associated with COVID-19 disease stage and mortality.

AimsTo audit the investigation, identification and treatment of Vitamin D deficiency within Men's Secure Services.BackgroundVitamin D and/or vitamin D deficiency has been suggested to play a role in the pathogenesis of mental illness. There is evidence that Vitamin D inadequacy is pandemic among rehabilitation patients in inpatient settings. Patients within secure hospitals are similarly considered to be at high risk, due to their limited solar exposure during often lengthy admissions. It has been suggested that these patients should be considered an ‘at-risk’ cohort, for whom Vitamin D supplementation should be routine. Men's secure services in Birmingham comprise of two medium secure units and a low secure rehabilitation unit. Here we present an audit of Vitamin D monitoring and treatment completed in 2019.MethodA three year retrospective review of electronic patient records, for all inpatients admitted within men's secure services as of 1 September 2019 (n = 188). Standards were based on the Trust accepted guidelines for management of Vitamin D deficiency.ResultKey findings included:- The majority of inpatients were Caucasian (43%) and African-Caribbean (24%). Ages ranged from 18 to 70, with a mean age of 39.Approximately two-thirds (65%) had been in hospital for over a year, of which 44% had been admitted for more than 3 years. The average length of admission was 885 days.Only 47% of patients had their Vitamin D level checked within the study period.Of those checked, 24% were tested within 1 month of admission. The mean duration between admission and Vitamin D testing was 464 days.Results ranged from 10.3 to 118.5nmol/L. A high rate of Vitamin D deficiency was identified (54%), whilst a further 16% had ‘inadequate’ levels.23% of those identified as requiring treatment did not receive any supplementation, whilst 59% of those with sufficient Vitamin D were prescribed treatment.Only 48% had their levels rechecked following treatment; of these, only 59% now had an adequate Vitamin D status.ConclusionThis audit demonstrates limited Vitamin D monitoring within male forensic inpatients. There was a high prevalence of Vitamin D insufficiency in this population, yet a substantial proportion of patients with identified deficiency were not prescribed any treatment. Ongoing monitoring and review of treatment effectiveness was poor. We argue that more consideration should be given to this population, with robust guidelines introduced for the treatment of this specific ‘at-risk group’.

SUMMARYEvidence from preclinical and clinical studies supports a role for vitamin D deficiency in many mental disorders. In this review, we discuss the role of vitamin D in the aetiology and treatment of schizophrenia and depression and their physical health comorbidities. Although observational studies support a potential association between vitamin D and schizophrenia and depression, sufficient high-quality evidence from clinical trials does not yet exist to establish a place for vitamin D supplementation in optimising clinical response or promoting physical health. Completed randomised controlled trials are needed to provide insights into the efficacy and safety of vitamin D in the management of mental disorders.LEARNING OBJECTIVESAfter reading this article you will be able to: •outline the epidemiology of vitamin D deficiency in schizophrenia•describe the associations of vitamin D with schizophrenia and depression•know how to assess, and consider treatment for, vitamin D deficiency.DECLARATION OF INTERESTF.G. has received support or honoraria for CME, advisory work and lectures from Bristol-Myers Squibb, Janssen, Lundbeck, Otsuka, Roche and Sunovion, and has a family member with professional links to Lilly and GSK, including shares.

AimsPatients with cystic fibrosis (CF) require supplementation of fat-soluble vitamins due to the effects of the disease on the pancreas and the resulting inability of absorb fat effectively.1The study aimed to assess the effectiveness of current of vitamin D supplementation to achieve adequate serum Vitamin D (25OHD) levels in paediatric CF patients.2 Secondly, this study assessed the effectiveness of ‘Stoss’ therapy (a high dose vitamin D therapy administered every three months) as an alternative to daily vitamin D supplementation for patients with known poor compliance.3MethodsVitamin D doses and serum 25OHD levels between January and December 2016 were reviewed for paediatric CF patients at a UK centre. Data was collected for 138 paediatric patients. The ‘clinical record summary’ system was used to extract the data which included age, hospital number, weight in 2015 and 2016, 25OHD levels from 2015 and 2016, vitamin D dose before each level and pancreatic status.Data was entered onto Statistical Package for the Social Sciences (SPSS) system for analysis. A paired T-test was conducted to ascertain if there was a significant difference in weekly/kg doses between patients that were sufficient (25OHD>50 nmol/L) and insufficient (25OHD<50 nmol/L).ResultsData was collected for a total of 138 patients. The data from only 70 patients was analysed when investigating the first objective, as all other patients did not have 25OHD levels available for both 2015 and 2016. A further five patients wereexcluded and analysed seperately due to receiving Stoss therapy. The weekly Vitamin D dose range was very wide for both years with 43% (n=40) of patients requiring additional vitamin D in addition to Aquadeks (CF multivitamin preparation). There was no significant difference in Vitamin D doses between patients with sufficient and insufficient 25OHD levels. This was thecase for both 2015 (p=0.432) and 2016 (p=0.192). The daily supplementation doses were successful at maintaining vitamin D sufficiency for 83% of patients in 2015 and 93% in 2016.Out of the 5 patients who received ‘Stoss’ therapy, 3 had an increase in 25OHD levels. However, only one of the patients had a significant increase leading to sufficient 25OHD levels. In 2 cases there was actually a 60%–68% decrease in 25OHD levels, which lead to these patients developing vitamin D deficiency.ConclusionThis study was useful in determining the effectiveness of current Vitamin D dosing. The results suggest that patients having insufficient 25OHD levels may not be due to an inadequacy of doses provided in the current guideline, as there was no significant difference in dose between patients with sufficient and insufficient 25OHD levels. Given the patient group, the difference could be attributable to a lack of compliance to daily therapies in the patients with insufficient 25OHD levels or even differences in individual responses to therapy.In this sample, ‘Stoss’ therapy is not effective in maintaining sufficient 25OHD levels. Although the data for this part of the study was very limited, it identifies a need to investigate the effectiveness of ‘Stoss’ therapy further.ReferencesFerguson JH, Chang AB.

This review summarizes studies discussing vitamin D status in adults and reveals that vitamin D deficiency/insufficiency is highly prevalent in adults and that current fortification and supplementation policies are inadequate. Background and aims: Studies suggest a crucial role for adequate vitamin D status in various health conditions including bone metabolism, cancer, cardiovascular diseases, and allergies. However, relatively little is known about poor vitamin D status and unmet needs in adults. This report aims to highlight the contribution of epidemiologic studies (through the identification of health effects and societal burden) to the development of vitamin D fortification and supplementation policies and reveal unmet global challenges in adults. Methods: In order to assess worldwide vitamin D status in adults, the search strategy combined the medical literature database MEDLINE (using PubMed) for the time period between January 1, 1980 and February 28, 2011, using the key words “vitamin D” “deficiency” and “insufficiency”, and included articles in which access to full text was possible and in which healthy adults were assessed according to one of four commonly used vitamin D threshold classifications. Results: This report reveals that vitamin D deficiency occurs in 4.10 % [95 % CI (confidence interval), 3.93 %, 4.27 %] to 55.05 % (54.07 %, 56.03 %) of adults, while insufficiency occurs in 26.07 % (24.82 %, 27.33 %) to 78.50 % (77.85 %, 79.16 %), depending on the classification used. However, lack of overlap in CIs and high value of I2 statistics indicate considerable heterogeneity between studies. Further, certain populations (i. e. dark-skinned individuals, immigrants, and pregnant women) may be at higher risk for poor vitamin D status. Conclusion: Current policies for vitamin D supplementation and fortification are inadequate and new guidelines are required to improve vitamin D status in adults.

AbstractObjectivesKidney transplant (KTx) recipients frequently have deficient or insufficient levels of serum vitamin D. Few studies have investigated the effect of cholecalciferol in these patients. We evaluated the efficacy of weekly cholecalciferol administration on parathyroid hormone (PTH) levels in stable KTx patients with chronic kidney disease stage 1–3.MethodsIn this retrospective cohort study, 48 stable KTx recipients (37 males, 11 females, aged 52 ± 11 years and 26 months post-transplantation) were treated weekly with oral cholecalciferol (7500–8750 IU) for 12 months and compared to 44 untreated age- and gender-matched recipients. Changes in levels of PTH, 25(OH) vitamin D (25[OH]D), serum calcium, phosphate, creatinine and estimated glomerular filtration rate (eGFR) were measured at baseline, 6 and 12 months.ResultsAt baseline, clinical characteristics were similar between treated and untreated patients. Considering the entire cohort, 87 (94.6%) were deficient in vitamin D and 64 (69.6%) had PTH ≥130 pg/mL. Serum calcium, phosphate, creatinine and eGFR did not differ between groups over the follow-up period. However, 25(OH)D levels were significantly higher at both 6 (63.5 vs. 30.3 nmol/L, p < 0.001) and 12 months (69.4 vs. 30 nmol/L, p < 0.001) in treated vs. untreated patients, corresponding with a significant reduction in PTH at both 6 (112 vs. 161 pg/mL) and 12 months (109 vs. 154 pg/mL) in treated vs. untreated patients, respectively (p < 0.001 for both).ConclusionsWeekly administration of cholecalciferol can significantly and stably reduce PTH levels, without any adverse effects on serum calcium and renal function.

Abstract The risk of vitamin D insufficiency in humans is a global problem that requires improving ways to increase vitamin D intake. Supplements are a primary means for increasing vitamin D intake, but without a clear consensus on what constitutes vitamin D sufficiency, there is toxicity risk with taking supplements. Chickens have been used in many vitamin D-related research studies, especially studies involving vitamin D supplementation. Our state-of-the-art review evaluates vitamin D metabolism and how the different hydroxylated forms are synthesized. We provide an overview with how vitamin D is absorbed, transported, excreted, and what tissues in the body store vitamin D metabolites. We also discuss a number of studies involving vitamin D supplementation with broilers and laying hens. Vitamin D deficiency and toxicity are also described and how they can be caused. The vitamin D receptor (VDR) is important for vitamin D metabolism. However, there is much more that can be understood with VDR in chickens. Potential research aims involving vitamin D and chickens should explore VDR mechanisms which could lead to newer insights with VDR. Utilizing chickens in future research to help with elucidating vitamin D mechanisms has great potential to advance human nutrition. Finding ways to increase vitamin D intake will be necessary because the coronavirus 2019 disease (COVID-19) pandemic is leading to increased risk of vitamin D deficiency in many populations. Chickens can provide a dual purpose with addressing pandemic-caused vitamin D deficiency: 1) vitamin D supplementation gives chickens added value with possibly leading to vitamin D-enriched meat and egg products; and 2) chickens’ use in research provides data for translational research. Expanding vitamin D-related research in chickens to include more nutritional aims in vitamin D status has great implications with developing better strategies to improve human health.
