Introduction: Metabolic syndrome includes a range of disorders that increase the risk of cardiovascular disease and diabetes mellitus. In this study, we examined the serum level of vitamin D3 in diabetic individuals with metabolic syndrome compared with non-diabetic individuals without metabolic syndrome and the association of serum vitamin D3 levels with metabolic syndrome and atherogenic factor (LDL/HDL). Material and Methods: In a case-control study, we included 110 women with metabolic syndrome according to ATP III criteria and 127 healthy women as a control group. Serum concentration of total cholesterol, LDL-C, FBS, HDL-C and serum triglyceride determined by enzymatic method and colorimetric and, serum level 25-(OH) vitamin D determined by ELISA. Results: It was found that the two healthy and metabolic groups were significantly different in terms of total cholesterol levels, LDL and triglyceride levels, HDL, VLDL, FBS, atherogenic index (LDL/HDL) and vitamin D levels (p<0.05). All participants in the control group and the patient and the whole study population were divided into two categories of insufficient and sufficient based on their measured serum concentrations of 25-(OH) vitamin D. There was a significant difference between the group with insufficient levels of vitamin D in comparison with the group with sufficient levels of vitamin D in terms of total cholesterol, LDL and triglyceride levels, HDL, VLDL, FBS and atherogenic index (LDL/HDL) (p=0.000). Conclusion: The present results showed that there is a significant relationship between level 25-(OH) D and atherogenic index (LDL/HDL) and the incidence of metabolic syndrome.

<p>In addition to known risk factors, the role of different micronutrients such as selenium in diabetes incidence has been proposed. Some previous studies have shown an association of selenium deficiency and type 2 diabetes mellitus, while other studies have not confirmed such a relationship. The aim of this study was to evaluate serum level of selenium in patients with Type 2 diabetes compared with the control group. This cross-sectional study was carried out on patients with type 2 diabetes in Zahedan, southeastern Iran. One hundred newly diagnosed type 2 diabetic patients were evaluated for serum selenium level. One hundred subjects from the general population who had normal fasting blood sugar levels were selected as the control group. The control group subjects were matched in pairs with each of patients on the basis of sex, age (± one year), and body mass index (±1). Serum level of selenium was determined by spectrometry method. Results were compared using t-test. The mean serum level of selenium in patients was 94.47±18.07 µg/L whereas in control group was 142.79±23.67 µg/L. The mean serum level of selenium was significantly different between the two groups (P&lt;0.001). Serum levels of selenium in diabetic patients with significant difference statistically were lower than the control group. In order to evaluate serum level of selenium in patients with diabetes, studies with larger sample size are required. Likewise, prospective studies along with selenium supplementation and investigating its effect on incidence of diabetes are accordingly needed.</p>

Introduction: Chronic rhinosinusitis may require referral to an ear, nose, and throat specialist for possible endoscopic sinus surgery if medical management fails. Vitamin D is one of the essential vitamins for the body that is effective in inflammatory processes. Therefore, it seems necessary to confirm the association between the deficiency of this vitamin and the occurrence of chronic rhinosinusitis with nasal polyposis. This study aimed to determine the relationship of vitamin D3 deficiency and chronic rhinosinusitis with nasal and sinus polyposis in patients referring to the Otorhinolaryngology Department of Valiasr Hospital, Birjand, Iran, in 2017. Methods: A case-control study was performed on individuals, including a group of patients with rhinosinusitis and a control group (n=20 each), referring to the Department of Ear, Nose, and Throat Diseases Department of Vali-asr Hospital. Among patients diagnosed with chronic rhinosinusitis, the cases that had polyps on endoscopic examination were included in the study. After completing the consent form, venous blood samples (10cc) were collected from the patients in fasting conditions. The electrochemical luminescence method was used for measuring the level of serum vitamin D. A questionnaire containing demographic information and clinical findings was completed by reviewing the patients' records. Data analysis was performed in SPSS software (Version. 22)using Chi-square and Mann-Whitney U-tests. Results: The mean and median scores of vitamin D level were obtained at14.13±12.99 and 10.25 in the case group, and 18.72±9.29 and 18.77 in the control group, respectively. The level of vitamin D was significantly higher in the control group than in the chronic group (P=0.04). In the case group, 16 (80%) patients lacked vitamin D and 3 patients had an insufficient level of vitamin D. In the control group, 13 (65%) patients lacked vitamin D and 4 cases had an insufficient level of vitamin D. There was no significant difference in vitamin D levels between the two groups (P=0.61). No significant difference was observed between the two clinical symptoms. Conclusion: It was revealed that the lack of vitamin D was likely to be an effective factor in the rhinosinusitis disease; therefore, proceedings need to be taken to cure the deficiency of this vitamin.

Glucose 6 Phosphate Dehydrogenase

Background: Multiple sclerosis (MS) and neuromyelitis optica (NMO) are both demyelinating disorders and oxidative stress is suggested to have a role in their pathogenesis. Glucose-6-phosphate dehydrogenase (G6PD) produces nicotinamide adenine dinucleotide phosphate (NADPH) via the pentose phosphate pathway. NADPH is not only involved in the synthesis of fatty acids necessary for myelination, but also it is involved in the defense against oxidative stress. Prescribing supplementary vitamin D as a part of the MS treatment plan can increase G6PD gene expression. The aim of this study was to determine the serum level of G6PD in patients with MS and NMO and its relationship with vitamin D, since it is yet to be explored thoroughly. Methods: In this case-control study, subjects were divided into three experimental and control groups. The experimental groups comprised 50 patients with relapsing-remitting MS (RRMS) who had a history of vitamin D consumption, 50 newly-diagnosed MS patients, and 50 patients with NMO. Control group included 65 healthy individuals. Serum level of G6PD was measured and compared among these groups. Results: No significant difference was seen between the G6PD level in patients with MS and NMO, but it should be noted that this level was significantly lower than the healthy group. G6PD serum level was significantly higher in patients with MS who had previously consumed supplementary vitamin D compared to those who had not. Conclusion: G6PD deficiency is observed in patients with MS and NMO. Also, supplementary vitamin D may induce favorable results on the G6PD level.

Objectives: This study aimed to evaluate whether vitamin D deficiency is associated with the severity of symptoms of irritable bowel syndrome (IBS) patients. Stress and gut inflammation can increase the serum level of corticotropin-releasing hormone (CRH) and interleukin-6 (IL-6), leading to a change in bowel movements. The aim of this study was to evaluate the anti-inflammatory and psychological effects of vitamin D3 supplementation on the symptom improvement of patients with a diarrhea-predominant form of IBS (IBS-D). Methods: Eighty-eight IBS-D patients (age: 18–65 years) based on Rome IV criteria who suffered from vitamin D deficiency and/or insufficiency were enrolled in this randomized, placebo-controlled trial from February 2017 to May 2018 at Rasoul-e-Akram Hospital, Tehran, Iran. Participants were randomly divided into two groups. The intervention group received 50,000 IU vitamin D3 weekly and the control group received a placebo for 9 weeks. All patients received Mebeverine 135 mg twice a day besides supplementation. The IBS Severity Score System (IBS-SSS), serum 25(OH) vitamin D3, CRH, and IL-6 were measured before and after interventions. Results: Seventy-four patients completed the study. The severity of IBS symptoms (p < 0.01) and IL-6 (p = 0.02) decreased significantly in the intervention group as compared to the control group, but there was no significant difference in the serum level of CRH. Also, in the treatment group, IBS-SSS and IL-6 were significantly reduced at the end of the study from baseline (p < 0.01 and p < 0.03, respectively). Conclusion: Our findings indicate that vitamin D3 supplementation can modulate the serum level of CRH and IL-6 and can improve symptoms in IBS-D patients. Vitamin D3 supplementation should be considered in IBS-D patients who suffer from vitamin D deficiency and/or insufficiency.

Background: Vitamin D3 is synthesized in skin and sequentially metabolized in liver and kidney in humans. It is well known for its function in maintaining calcium and phosphorus homeostasis and promoting bone mineralization. The primary objective of this study was to evaluate vitamin D3 level in pregnant women who were suffering from gestational diabetes mellitus and comparing it with the control groups. Materials and Methods: This case control study was conducted on 100 pregnant women who were attending the inpatient and outpatient clinics of Obstetrics department, Tanta University Hospital, who were divided into two equal groups.Group A (control group): Fifty apparently healthy pregnant women at 24th-28th weeks of gestation. Group B (study group): Fifty pregnant women had gestational diabetes. Results: There is significant increase between the two studied groups according to HbA1c, also there is decrease between the two groups as regards VIT D. Mean HbA1c % was statistically significant higher in the study group versus control group. There was statistical significant difference noted between mean serum level of vitamin D among the two studied groups. A statistically significant negative correlation was observed between serum 25 OH vitamin D and HbA1c among our cases (r=- 0.745) (p ≤ 0.001). Mean serum vitamin D was significantly lower in cases with complications than those with normal outcome. Conclusion: Vitamin D deficiency may have a positive relationship with gestational diabetes mellitus.

Background: Vitamin D deficiency can play a role in cardiovascular conditions, such as coronary artery disease, heart failure and hypertension. Vitamin D deficiency can activate the renin-angiotensin-aldosterone system, which in turn affects the cardiovascular system. Thus, a relationship between vitamin D deficiency and thoracic aortic dilatation (TAD) and aneurysm could be postulated. In this study, we compared 25-OH vitamin D levels between TAD and control groups. Patients and methods: This study included 87 patients with TAD who were 40 - 70 years old. The control group consisted of 93 patients who were 40 - 70 years old and did not have TAD. A transthoracic echocardiography was performed on each patient. Along with routine tests, the 25-OH vitamin D and parathormone (PTH) levels were analyzed. Results: No statistically significant difference was found between the two groups regarding their basic characteristics. The average PTH level of the TAD group was higher than that of the control group (94.87 ± 44.96 and 66.39 ± 30.58 pg/ml, respectively; p < 0.001). The average 25-OH vitamin D level of the TAD group was lower than that of the control group (11.89 ± 7.54 and 15.98 ± 4.98 ng/ml, respectively; p = 0.001). The initial conventional echocardiographic parameters of both groups were comparable. Logistic regression analysis revealed that the PTH and 25-OH vitamin D levels were independent predictors of TAD. Conclusions: Vitamin D deficiency was found as an independent factor associated with TAD.

Background: This study assessed the effects of weekly vitamin D (VD) supplementation on clinical and biological parameters after scaling and root planning (SRP) in the treatment of periodontitis and served to validate the VD dosage regimen. Methods: It was a monocentric, randomized, double-blind, placebo-controlled clinical trial with 6 months follow-up. Healthy Caucasian periodontitis patients presenting serum 25(OH) vitamin D3 below 30 ng/mL were randomly allocated to test group (SRP + VD 25,000 international units (IU)/week) or the control group (SRP + placebo). Results: A total of 59 patients were screened, 27 were included and 26 completed 3 months (M) and 21 completed 6M control. Test (n = 13) and control groups (n = 14) had similar 25(OH) vitamin D3 levels at baseline (17.6 ± 7.4 vs. 14.4 ± 5.2, respectively). After one month, there was a significant difference between groups (32.9 ± 5.2 vs. 16.1 ± 4.7), also seen at M3 and M6 (t-test, p < 0.001). Periodontal treatment was successful in both groups, since it resulted in a reduction of all measured clinical parameters at M3 and M6 (probing pocket depth (PPD), full mouth bleeding and plaque). However, the reduction in PPD was greater in the test group. Conclusions: In this short-term pilot study, no significant differences were observed between two groups. However, supplementation with VD tended to improve the treatment of periodontitis in patients with initial 25(OH) vitamin D3 < 30 ng/mL and proved safe and efficacious. NCT03162406.

Introduction The aim of this study was to compare serum vitamin D between fertile and infertile men in endemic area of vitamin D deficiency. The role of vitamin D in all aspects of human health has attracted a great interest. Vitamin D effect on female fertility and to a lesser extent in men is under investigation. Previous researchers have found meaningful positive relationship between semen quality and serum vitamin D level. However, in endemic area of vitamin D deficiency, this effect is under question. Methods Serum 25-OH-Vitamin D was compared between infertile male patients and fertile control group. Infertile cases were from patients of our infertility clinic and fertile controls from healthy cases with at least one child below 5 years of age. SPSS version 19 was used for statistical analysis (Kolmogorov-Smirnov test and Mann-Whitney test). Results Between 116 fertile and 114 infertile men who entered the study, serum level of 20 was a critical point, which patients with upper serum level had significantly better spermogram. In addition to it, even in vitamin D deficient patients and controls, fertile controls had higher serum vitamin D. Conclusions There is a positive correlation between serum level of vitamin D and spermogram quality, even in vitamin D deficient areas. Fertile people have a higher level of serum vitamin D in comparison to infertile patient in aforementioned areas.

Latar belakang: Rinitis alergi (RA) adalah peradangan atau inflamasi pada mukosa atau selaput lendir hidung yang didasari oleh reaksi hipersensitivitas tipe 1 dan diperantarai IgE. Rinitis alergi merupakan tipe rinitis kronis yang sering dijumpai. Sebanyak 30-50% penderita rinitis memiliki pemicu alergi dan prevalensinya cenderung meningkat. Vitamin D mempunyai peran memodulasi respon imun alamiah dan adaptif. Banyaknya pengaruh vitamin D dalam sistem imun diharapkan dapat mengatur aktivitas berbagai sel kekebalan, serta fungsi kekebalan tubuh dari epitel sel pada RA, namun konsensus sebagai bagian terapi RA saat ini masih belum ada. Tujuan: Mengetahui pengaruh pemberian vitamin D3 terhadap kadar vitamin D (25(OH)D) dan sel T Regulator (T reg) pada rinitis alergi. Metode: Penelitian eksperimental murni dengan rancangan penelitian randomized clinical trial (RCT) double blind, pre and post test control group dengan perlakuan berupa pemberian terapi sesuai ARIA (Allergic Rhinitis and its Impact on Asthma) dan vitamin D3 oral diberikan selama 4 minggu. Dilakukan penilaian VAS (Visual Analogue Scale), TNSS (Total Nasal Symptom Score), serta kadar vitamin D darah dan persentase sel T reg pada awal dan 4 minggu setelah perlakuan. Hasil: Pada kelompok perlakuan terdapat perbedaan bermakna kadar vitamin D sebelum dan sesudah perlakuan (p=0,01). Terdapat perbedaan yang bermakna dari peningkatan persentase sel T reg pada kelompok perlakuan dibandingkan kelompok kontrol (p=0,02). Terdapat hubungan antara peningkatan persentase sel T reg dengan kadar vitamin D pada kelompok perlakuan (p=0,01). Kesimpulan: Vitamin D3 dapat meningkatkan kadar vitamin D dan persentase sel T reg secara bermakna pada pasien rinitis alergi persisten sedang berat. Kata kunci: Rinitis alergi, vitamin D, sel T regulator ABSTRACT Background: Allergic rhinitis (AR) is an inflammatory disease of nasal mucosa based on type 1 hypersensitivity reaction and mediated by IgE. Allergic rhinitis is the most common type of chronic rhinitis. About 30±50% of patients with allergic rhinitis have trigger factors and its prevalence is increasing. Vitamin D has a function in modulation of innate and adaptive responses. The role of vitamin D in immune system is expected to regulate various immune cells activity, and the immune function of AR epithelial cells, but there were no consensus yet about vitamin D as part of AR therapy. Objective: To identify the effect of vitamin D3 on level of vitamin D (25(OH)D) and T regulator (T reg) cells in allergic rhinitis patients. Methods: This study was purely experimental research with randomized clinical trial, double-blind, pre and post test control group treated with appropriate therapy according to ARIA (Allergic Rhinitis and its Impact on Asthma) and vitamin D3 given orally for 4 weeks. Evaluations of VAS (Visual Analogue Scale) and TNSS (Total Nasal Symptom Score) value, vitamin D levels and the percentage of T reg cells were carried out at baseline and 4 weeks after treatment. Results: In the treatment group there was a significant difference between vitamin D levels before and after treatment (p=0.01). There was a significant difference on increased percentage of T reg cells in the treatment group compared with the control group (p=0.02). There was a correlation between the increasing percentage of T reg cells with vitamin D levels in the treatment group (p=0.01). Conclusion: Vitamin D supplementation could increase the level of vitamin D and the percentage of T reg cells significantly in patients with severe persistent allergic rhinitis.
