Premenstrual syndrome (PMS) is a common disorder in the reproductive age that negatively significant impacts on women's quality of life. This randomized clinical trial study was undertaken to investigate the effect of vitamin D supplementation on inflammatory and antioxidant markers in 44 vitamin D deficient (25(OH)D < 20 ng/mL) students with PMS. Participants received either 50,000 IU vitamin D3 or a placebo pearl fortnightly for 4 months. At the baseline and in the last 2 months of interventio ...[more]

Project description:BackgroundIt has been suggested that premenstrual syndrome (PMS) may derive from either elevated oxidative stress or reduced antioxidant vitamin levels in the body; however, these relationships have been minimally studied in a large cohort of healthy women. Our objective was to estimate the association between serum concentrations of antioxidant vitamins (A, C, and E) and markers of oxidative stress (F2-isoprostane) with symptoms and severity of PMS.MethodsThe BioCycle study was a prospective cohort study following 259 healthy premenopausal women aged 18-44 years for up to 2 menstrual cycles. Frequency/severity of 20 PMS symptoms were assessed via questionnaires 4 times/cycle, and antioxidant vitamins and oxidative stress biomarkers were measured up to 8 times/cycle to correspond with specific cycle phases. Generalized linear models were used to estimate associations between mean antioxidant concentrations and oxidative stress biomarkers with PMS symptoms and severity; linear mixed models were used to evaluate associations with symptom severity scores within groups (e.g. depression, cravings, pain).ResultsHigher concentrations of serum antioxidant vitamins were largely not associated with prevalence or severity of PMS symptoms. Though a few associations were observed, only associations between mean γ-tocopherol and decreased odds of swelling of the hands/feet survived adjustment for multiple comparisons (OR 0.33, 95% CI 0.16, 0.65, per ug/dL). However, F2-isoprostanes were associated with prevalence and severity of several symptoms specifically related to depression and cravings (depression score β = 0.07, 95% CI 0.02, 0.12, per 10 ug/dL; cravings score β = 0.16, 95% CI 0.10, 0.22, per 10 ug/dL), as well as with classification of PMS severity (OR 1.07, 95% CI 1.01, 1.14, per 10 pg/dL), with these associations surviving adjustment for false discovery rate.ConclusionsF2-isoprostanes, but not antioxidant vitamins, were associated with select PMS symptoms, as well as symptom and severity categories. Specific symptom relationships merit further research.

Project description:In disease settings, vitamin D may be important for maintaining optimal lung epithelial integrity and suppressing inflammation, but less is known of its effects prior to disease onset. Female BALB/c dams were fed a vitamin D3-supplemented (2280 IU/kg, VitD+) or nonsupplemented (0 IU/kg, VitD-) diet from 3 weeks of age, and mated at 8 weeks of age. Male offspring were fed the same diet as their mother. Some offspring initially fed the VitD- diet were switched to a VitD+ diet from 8 weeks of age (VitD-/+). At 12 weeks of age, signs of low-level inflammation were observed in the bronchoalveolar lavage fluid (BALF) of VitD- mice (more macrophages and neutrophils), which were suppressed by subsequent supplementation with vitamin D3 There was no difference in the level of expression of the tight junction proteins occludin or claudin-1 in lung epithelial cells of VitD+ mice compared to VitD- mice; however, claudin-1 levels were reduced when initially vitamin D-deficient mice were fed the vitamin D3-containing diet (VitD-/+). Reduced total IgM levels were detected in BALF and serum of VitD-/+ mice compared to VitD+ mice. Lung mRNA levels of the vitamin D receptor (VDR) were greatest in VitD-/+ mice. Total IgG levels in BALF were greater in mice fed the vitamin D3-containing diet, which may be explained by increased activation of B cells in airway-draining lymph nodes. These findings suggest that supplementation of initially vitamin D-deficient mice with vitamin D3 suppresses signs of lung inflammation but has limited effects on the epithelial integrity of the lungs.

Project description:The premenstrual syndrome (PMS) is a series of physical, mental, and behavioral symptoms with various severities, and disturbs social and personal relationships. The syndrome appears during luteal phase of the menstrual cycle and is a common disorder of reproductive age. Different treatments have been introduced for the syndrome due to its unknown complicated causes. Vitamin B1 (Thiamin) may reduce symptoms of the syndrome through affecting the performance of coenzymes in the metabolism of carbohydrates and main branch of amino acid that plays an important role in appearance of physical and mental symptoms of the PMS. Vitamin B1 is the first water-soluble discovered vitamin. As it is effective in neural activity and muscle tonus in different body activities, including hematopoiesis, metabolism of carbohydrates, activities of the central nervous system and neuromuscular system, etc., it can be effective in this dysmenorrhea that is a disorder resulting from uterine muscular contraction. There are no enough studies and research on the effect of vitamin B1 on the symptoms of PMS, therefore, this study was conducted to determine the effect of vitamin B1 on the symptoms of PMS in students residing at dormitories of Jahrom University of Medical Sciences in 2013.In this double-blind placebo-controlled clinical trial, 80 students with PMS residing at dormitories of Jahrom University of Medical Sciences were divided randomly into two groups, vitamin B1 and placebo. The severity of the symptoms of PMS in two cycles, before the intervention and during the intervention, was recorded by the students. The data were collected using an information collection form, PMS provisional diagnosis form, daily status record form, Beck Depression Inventory. The data were analyzed using descriptive and inferential statistics.There was no significant difference among the studied variables in terms of confounding variables. The comparison of vitamin B1 group before the intervention with that after the intervention showed that vitamin B1 reduced mean mental (35.08%) and physical (21.2%) symptoms significantly (P < 0.0001). Moreover, there was a significant difference between vitamin B1 and placebo groups in terms of mean mental and physical symptoms, as mean symptoms in vitamin B1 group was significantly lower than that in the placebo group (P < 0.0001).It seems that vitamin B1 is effective in recovery of mental and physical symptoms of PMS. Therefore, this vitamin can be used to reach a major goal of midwifery, that is, reduction of symptom severity of PMS, without any side effects.

Project description:Studies suggest that vitamin D deficiency is a risk factor for cardiovascular disease and diabetes. Vitamin D deficiency is prevalent in HIV patients but the effect of vitamin D supplementation on cardiovascular risk in this population is unknown.We conducted a randomized, double-blind, placebo-controlled trial among 45 HIV-infected adults in Cleveland (OH, USA) on stable antiretroviral therapy with durable virological suppression and a baseline serum 25-hydroxyvitamin D level of ?20 ng/ml. Participants were randomized 2:1 to vitamin D3 4,000 IU daily or placebo for 12 weeks. The primary outcome was a change in flow-mediated brachial artery dilation (FMD).Baseline demographics were similar except for age (vitamin D versus placebo, mean ±sd 47 ±8 versus 40 ±10 years; P=0.009). Both groups had reduced FMD at baseline (median values 2.9% [IQR 1.6-4.8] for vitamin D versus 2.5% [IQR 1.7-6.4] for placebo; P=0.819). Despite an increase in the concentration of serum 25-hydroxyvitamin D from baseline to 12 weeks (5.0 ng/ml [IQR -0.9-7.4] versus -1.9 ng/ml [IQR -4.0-0.1] for vitamin D versus placebo, respectively; P=0.003), there was no difference in FMD change (0.55% [IQR -1.05-2.13] versus 0.29% [IQR -1.61-1.77]; P=0.748). Vitamin D supplementation was associated with a decrease in total and non-high-density lipoprotein cholesterol, and an increase in indices of insulin resistance.Among HIV-infected individuals with vitamin D deficiency, supplementation with 4,000 IU vitamin D3 daily for 12 weeks modestly improved vitamin D status and cholesterol but worsened insulin resistance without change in endothelial function. The mechanisms of resistance to standard doses of vitamin D and the complex role of vitamin D in glucose metabolism in this population require further investigation.

Project description:Bone turnover markers (BTMs) are used to evaluate bone health together with bone mineral density and fracture assessment. Vitamin D supplementation is widely used to prevent and treat musculoskeletal diseases but existing data on vitamin D effects on markers of bone resorption and formation are inconsistent. We therefore examined the effects of vitamin D supplementation on bone-specific alkaline phosphatase (bALP), osteocalcin (OC), C-terminal telopeptide (CTX), and procollagen type 1 N-terminal propeptide (P1NP). This is a post-hoc analysis of the Styrian Vitamin D Hypertension Trial, a single-center, double-blind, randomized, placebo-controlled trial (RCT) performed at the Medical University of Graz, Austria (2011-2014). Two hundred individuals with arterial hypertension and 25-hydroxyvitamin D (25[OH]D) levels <75 nmol/L were randomized to 2800 IU of vitamin D daily or placebo for eight weeks. One hundred ninety-seven participants (60.2 ± 11.1 years; 47% women) were included in this analysis. Vitamin D had no significant effect on bALP (mean treatment effect (MTE) 0.013, 95% CI -0.029 to 0.056 µg/L; p = 0.533), CTX (MTE 0.024, 95% CI -0.163 to 0.210 ng/mL, p = 0.802), OC (MTE 0.020, 95% CI -0.062 to 0.103 ng/mL, p = 0.626), or P1NP (MTE -0.021, 95% CI -0.099 to 0.057 ng/mL, p = 0.597). Analyzing patients with 25(OH)D levels <50 nmol/L separately (n = 74) left results largely unchanged. In hypertensive patients with low 25(OH)D levels, we observed no significant effect of vitamin D supplementation for eight weeks on BTMs.

Project description:Objective The aim of this study was to investigate the existence, knowledge, and the attitude of female students towards premenstrual syndrome (PMS). Methods This cross-sectional study was conducted in three universities in Karachi, Pakistan. A total of 448 female students participated in the study. The clinical criterion of American College of Obstetricians and Gynecologists (ACOG) for PMS was used to assess the prevalence of PMS in the participants. The questionnaire was set in four parts, one each to assess the knowledge, the attitude, and practices regarding PMS and one to assess the gap between self-perceived PMS and actual PMS. Data were analyzed descriptively using the Statistical Package for the Social Sciences (SPSS), version 20 (IBM SPSS Statistics, Armonk, NY). Results The majority (96.4%) of female students were aware of PMS, while only 19% females knew about premenstrual dysphoric disorder. The self-reported prevalence of PMS was 79.5% and the prevalence using the ACOG criteria was 23.9%. Common symptoms were irritability, angry outbursts, depression, breast tenderness, and gastrointestinal problems. More than half (60.4%) of the participants reported PMS disturbed their normal routine, while 81.5% reported stress exacerbated their symptoms. The majority (77.5%) of women believed PMS was a significant issue to be discussed but 49.4% did not take treatment for their PMS. Conclusion There is a significant impact of PMS in the lives of Pakistani women, and it is a common problem all over the globe. Despite the growing awareness, there remains a considerable deficiency of knowledge about the necessity to consult a doctor or seek treatment for their symptoms.

Project description:Objectives:Obese, African-American (AA) adolescents are at increased risk for vitamin D deficiency. The primary objective of this pilot study was to examine the effect of vitamin D supplementation upon 25-hydroxy vitamin D (25OHD) levels in obese, AA adolescents. Methods:A randomized, double-blinded, controlled pilot study included 26 obese (BMI???95%ile), vitamin D deficient (25OHD?<?20?ng/mL), pubertal AA adolescents (ages 12-17). Subjects received cholecalciferol 1000?IU or 5000?IU daily for 3?months. Serum 25OHD, vitamin D binding protein, parathyroid hormone, and cardiometabolic risk markers were obtained at baseline and post-treatment. Results:Of 39 subjects enrolled, 26 (67%) were vitamin D deficient (mean 25OHD 12.0?±?3.8?ng/mL) at baseline and were randomized, with 22 completing the study. Sex, age, season, pubertal stage, BMI, insulin resistance (HOMA-IR) and 25OHD were similar at baseline between the 1000?IU and 5000?IU groups. Post-treatment, 25OHD increased less in the 1000?IU group (5.6?ng/mL, p?=?0.03) vs. the 5000?IU group (15.6?ng/mL, p?=?0.002). 83% of the 5000?IU group and 30% of the 1000?IU group reached post-treatment 25OHD???20?ng/mL (p?=?0.01); 50% of the 5000?IU group, but no subject from the 1000?IU group, achieved 25OHD???30?ng/mL (p?=?0.009). We detected no group differences in mineral metabolites or cardiometabolic risk markers following supplementation. Conclusions:Cholecalciferol dosing in excess of the current Institute of Medicine dietary reference intakes was required to achieve 25OHD levels ?20?ng/mL in obese, AA adolescents. Supplementation of 5000?IU may be required to achieve the desired goal.

Project description:BackgroundAntioxidant vitamin (vitamin E, beta-carotene, and vitamin C) are widely used for preventing major cardiovascular outcomes. However, the effect of antioxidant vitamin on cardiovascular events remains unclear.Methodology and principal findingsWe searched PubMed, EmBase, the Cochrane Central Register of Controlled Trials, and the proceedings of major conferences for relevant literature. Eligible studies were randomized controlled trials that reported on the effects of antioxidant vitamin on cardiovascular outcomes as compared to placebo. Outcomes analyzed were major cardiovascular events, myocardial infarction, stroke, cardiac death, total death, and any possible adverse events. We used the I(2) statistic to measure heterogeneity between trials and calculated risk estimates for cardiovascular outcomes with random-effect meta-analysis. Independent extraction was performed by two reviewers and consensus was reached. Of 293 identified studies, we included 15 trials reporting data on 188209 participants. These studies reported 12749 major cardiovascular events, 6699 myocardial infarction, 3749 strokes, 14122 total death, and 5980 cardiac deaths. Overall, antioxidant vitamin supplementation as compared to placebo had no effect on major cardiovascular events (RR, 1.00; 95%CI, 0.96-1.03), myocardial infarction (RR, 0.98; 95%CI, 0.92-1.04), stroke (RR, 0.99; 95%CI, 0.93-1.05), total death (RR, 1.03; 95%CI, 0.98-1.07), cardiac death (RR, 1.02; 95%CI, 0.97-1.07), revascularization (RR, 1.00; 95%CI, 0.95-1.05), total CHD (RR, 0.96; 95%CI, 0.87-1.05), angina (RR, 0.98; 95%CI, 0.90-1.07), and congestive heart failure (RR, 1.07; 95%CI, 0.96 to 1.19).Conclusion/significanceAntioxidant vitamin supplementation has no effect on the incidence of major cardiovascular events, myocardial infarction, stroke, total death, and cardiac death.

Project description:Premenstrual syndrome (PMS) is a cyclically occurring combination of various symptoms, leading to decreased life quality among approximately 30% of women of childbearing age. PMS etiology remains unknown; however, there are some suggestions that inappropriate inflammatory response and oxidative stress are involved. This study aimed to systematically review case-control and cross-sectional studies investigating inflammation markers, oxidative stress, and antioxidant status among women with PMS and controls. The study protocol was registered with PROSPERO (no. CRD42020178545), and the authors followed the guidelines for performing a systemic review recommended by Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). By searching PubMed and Scopus databases (up to 8 January 2021), six case-control studies and five cross-sectional studies of medium or high quality were classified to the review. The systematic review included 652 women with PMS and 678 controls, for whom 36 eligible markers were determined. Limited evidence indicates increased levels of inflammatory parameters and suggests decreased antioxidant status in PMS women. Insufficient data with inconsistent results made it impossible to formulate a firm conclusion on the contribution of oxidative stress in PMS occurrence. To acknowledge the role of inflammation, oxidative stress, and antioxidant status in the pathophysiology of PMS, further research with case-control design and large study groups is needed.
