e18004 Background: Vitamin-D deficiency is a global problem due to lack of sunlight exposure or dietary deficiency. Few studies have correlated vitamin-D deficiency with poor outcome in patients with diffuse large B-cell lymphomas and chronic lymphocytic leukemia. Expression of vitamin-D receptors on both normal and malignant hematopoietic cells suggests its possible role in pathogenesis, response to therapy and as a potential therapeutic target in haematological cancers. Given the high prevalence of malnutrition in our country and the potential impact of vitamin-D deficiency in haematological malignancies we conducted this prospective study to identify its prevalence in this subset of patients. Methods: Consecutive patients (15-50 years) with de novo haematological cancers who were registered at our centre over a three months period were evaluated. Patients who had received bisphosphonates or calcium and vitamin-D supplementation were excluded. Demographic variables, performance status, lifestyle (sedentary or non-sedentary), diet (vegetarian or mixed), consumption of milk products, serum 25 (OH) D, albumin and calcium levels were recorded. Levels <30ng/ml and <20ng/ml were considered as insufficient and deficient respectively. Results: A total of 126 patients (70% males) were enrolled. Median age was 35 years. Distribution as per histology was acute leukemia-59, lymphomas-53, chronic myeloid leukemia-14. 78% patients had non-sedentary life style and were consuming mixed diet and milk. 90% patients had performance status ≤2. Serum albumin>3.5 gm/dL and normal calcium levels were seen in 90%. Vitamin-D deficiency was seen in 12% patients whereas 73% patients were vitamin D insufficient. Keeping the cut-off <25 ng/mL, 82% patients were deficient. Deficiency did not correlate with age, underlying diagnosis, lifestyle or dietary habits. Conclusions: Our study identified a very high prevalence of vitamin-D deficiency in patients with haematological malignancies. This could be one of the factors responsible for the aggressive nature of disease and poor outcome in our patients.

Introduction: Organophosphate (OP) pesticide poisoning is a major challenging public-health problem in developing countries. Vitamin D deficiency is pandemic, yet it is the most under-diagnosed and under-treated nutritional deficiency in the world and it has been reported to be clinically correlated with psychiatric illness and manifestation of severe systemic inflammatory response syndrome like ARDS. Thus vitamin D deficiency may affect clinical course and outcome in cases of OPP. Aim: To evaluate status of 25 hydroxyvitamin D (25(OH)D) level in OP poisoning and its correlation with outcome of such patients. Materials and Methods: Serum 25(OH)D levels were measured at the time of hospitalization by electro-chemiluminescent Assay in 96 patients (76 male and 20 female) suffering from OP poisoning. Diagnosis of OP poisoning was made by history of poisoning including container of the poison brought by patient’s relative, clinical examination and measurement of serum butyrylcholinesterase activity. All patients were evaluated as per Performa and follow up till discharge. Results: Mean level of 25(OH)D in our cases was 24.57±9.91ng/ml and 66.7% had low levels of 25(OH)D. Our study shows linear relationship between 25(OH)D level and duration of hospital stay. All cases of OP poisoning who developed severe manifestations like ARDS, Intermediate syndrome (IMS) were having significant 25(OH)D deficiency. Our study also shows lower levels of 25(OH)D were associated with poor outcome (11.27±3.21vs 27.02±8.54, p<0.001). Conclusion: Vitamin D deficiency in OP poisoning is associated with longer hospital stay, more requirement of ventilator support and high prevalence of complication (ARDS and IMS) and poor outcome. Awareness of 25(OH)D level in patients with OP poisoning may be important to improve outcome.

Background: Vitamin D exerts multiple pleiotropic effects beyond its role in calcium-phosphate metabolism. Growing evidence suggests an association between hypovitaminosis D and sleep disorders, thus increasing the interest in the role of this vitamin in the regulatory mechanisms of the sleep-wake cycle. Objective: The study aimed to explore and summarize the current knowledge about the role of vitamin D in sleep regulation and the impact of vitamin D deficiency on sleep disorders. Methods: The main regulatory mechanisms of vitamin D on sleep are explained in this study. The literature was scanned to identify clinical trials and correlation studies showing an association between vitamin D deficiency and sleep disorders. Results: Vitamin D receptors and the enzymes that control their activation and degradation are expressed in several areas of the brain involved in sleep regulation. Vitamin D is also involved in the pathways of production of Melatonin, the hormone involved in the regulation of human circadian rhythms and sleep. Furthermore, vitamin D can affect sleep indirectly through non-specific pain disorders, correlated with alterations in sleep quality, such as restless legs syndrome and obstructive sleep apnea syndrome. Conclusions: : Vitamin D has both a direct and an indirect role in the regulation of sleep. Although vitamin D deficiency has been associated to sleep disorders, there is still scant evidence to concretely support the role of vitamin D supplementation in the prevention or treatment of sleep disturbances; indeed, more intervention studies are needed to better clarify these aspects.

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.

Vitamin D deficiency has been reported previously in patients with osteoarthritis undergoing total hip arthroplasty. We found a high prevalence of vitamin D deficiency in elderly patients with advanced knee osteoarthritis scheduled for total knee replacement and also a significant association with a lower preoperative functional state. A review of the literature is given on vitamin D deficiency in patients with knee osteoarthritis and the association with lower outcome scores after arthroplasty is discussed.

Background: Systemic Lupus Erythematosus (SLE) is a systemic autoimmune disease characterised by abnormal activation of the immune system, chronic inflammation and organ damage. Lupus patients are more prone to be vitamin D deficient. However, current evidence is not conclusive with regards to the role played by vitamin D in SLE development, progression, and clinical manifestations. Objective: Here, we will summarise the current knowledge about vitamin D deficiency prevalence, risk factors, molecular effects, and potential pathogenic role in SLE. We will focus on the link between vitamin D deficiency and lupus clinical manifestations, and on the clinical trials assessing the effects of vitamin D supplementation in SLE. Method: A detailed literature search was performed exploiting the available databases, using “vitamin D and lupus/SLE” as keywords. The relevant interventional trials published over the last decade have been considered and the results are reported here. Conclusion: Several immune cells express vitamin D receptors. Thus, an immunomodulatory role for vitamin D in lupus is plausible. Numerous observational studies have investigated the relationship between vitamin D levels and clinical/serological manifestations of SLE with contrasting results. Negative correlations between vitamin D levels and disease activity, fatigue, renal and cardiovascular disease, and anti-dsDNA titres have been described but not conclusively accepted. In experimental models of lupus, vitamin D supplementation can improve the disease. Interventional trials have assessed the potential therapeutic value of vitamin D in SLE, but further larger studies are needed.
