Statin and vitamin d insufficiency

BACKGROUND: Smith-Lemli-Opitz syndrome (SLOS) is a multiple congenital malformations syndrome caused by defective cholesterol biosynthesis. Affected individuals show cholesterol deficiency and accumulation of various precursor molecules, mainly 7-dehydrocholesterol and 8-dehydrocholesterol. There is currently no cure for SLOS, with cholesterol supplementation being primarily a biochemical therapy of limited evidence. However, several anecdotal reports and preclinical studies have highlighted statins as a potential therapy for SLOS...

INTRODUCTION: Atherosclerotic cardiovascular disease (ASCVD) is the major cause of morbidity and mortality worldwide. Statins provide primary and secondary ASCVD prevention. Intolerance due to statin-associated myalgias reduces long-term adherence, thus muting potential benefits. AIM: Our analysis sought to determine whether transition from a lipophilic statin to a water-soluble statin, or correction of subclinical hypothyroidism and/or vitamin D insufficiency/deficiency (metabolic abnormalities), improved statin tolerance...

INTRODUCTION: Although low vitamin D levels are associated with statin-associated muscle symptoms (SAMS), it remains unclear if vitamin D supplementation leads to symptom improvement. AIM: We performed a systematic review to evaluate the association of vitamin D supplementation with resolution of SAMS. METHODS: We searched Medline (PubMed), Embase and Cochrane Library till 12 December 2021. Full length articles that reported on the association between vitamin D supplementation in adult patients with SAMS were included...

OBJECTIVES: Statin-induced myopathy is one of the major causes of poor adherence and discontinuation of this medication. There are contrary results regarding association of vitamin D insufficiency with statin-induced myopathy. This study was done to determine the effect of the vitamin D3 analogue alfacalcidol on Rosuvastatin-induced myopathy in rats. Methodology . Animals were divided into six groups with 6 rats in each group. Groups I and II acted as controls, Group III and Group IV were administered Rosuvastatin 120 mg/kg/day and 160 mg/kg/day, Groups V and VI were administered alfacalcidol 0...

INTRODUCTION AND AIM: There are inconsistent findings on the association between human non-alcoholic fatty liver disease (NAFLD) and vitamin D, perhaps due to insufficient specificity for gender and obesity status. We aimed to assess whether serum levels of 25-hydroxyvitamin D are associated with unexplained elevated alanine aminotransferase (ALT) in general population across gender and body mass index (BMI) levels. MATERIALS AND METHODS: A cross-sectional analysis of a population-based cohort with a nationwide-distribution using electronic medical database...

BACKGROUND: Both vitamin D preparations and high-dose statin therapy were found to reduce thyroid antibody titers. OBJECTIVE: The purpose of this study was to assess whether vitamin D status determines the effect of statin therapy on thyroid autoimmunity. METHODS: The study population consisted of 39 euthyroid women with Hashimoto's thyroiditis and moderate or moderately high cardiovascular risk divided into two groups: women with vitamin D deficiency or insufficiency (group A; n=19) and women with normal vitamin D status (group B, n=20)...

BACKGROUND: Serum creatine kinase (CK) levels are higher after eccentric, muscle-damaging exercise in statin-treated patients. This could contribute to the increased statin-associated muscle symptoms reported in physically active individuals. OBJECTIVE: We tested the hypothesis in this pilot study that creatine (Cr) monohydrate supplementation would reduce the CK response to eccentric exercise in patients using statins to determine if Cr supplementation could be a strategy to mitigate statin-associated muscle symptoms in physically active individuals...

OBJECTIVE: The aim of the study was to investigate the association between high-density lipoprotein (HDL) and bone status taking into account serum vitamin D levels in postmenopausal Iranian women. METHODS: During January 2015 and February 2016, a total of 488 postmenopausal Iranian women participated in this cross-sectional study, all of whom were not taking osteoporosis medication and were not suffering from any chronic disorder. Dual X-ray absorptiometry was used to assess bone mineral density (BMD) of the total hip, femoral neck, and lumbar vertebrae (L2-L4)...

BACKGROUND: Vitamin D preparations reduce titers of thyroid antibodies in women with autoimmune thyroiditis. The same effect was induced by high-dose, but not moderate-dose-, statin therapy. No previous study has investigated the impact of concomitant treatment with a statin and vitamin D on thyroid autoimmunity. METHODS: The study included three matched groups of women with Hashimoto's thyroiditis and low vitamin D status. Groups B (n=19) and C (n=20) were treated with vitamin D (2000 IU daily)...

BACKGROUND AND AIMS: Low vitamin D (VITD) may contribute to statin-associated muscle symptoms (SAMS). We examined the influence of baseline and change in VITD in patients with verified SAMS. METHODS: SAMS was verified in 120 patients with prior statin muscle complaints using 8-week randomized, double-blind crossover trials of simvastatin (SIMVA) 20 mg/d and placebo. 25 (OH)vitamin D was measured at each phase of the trial. RESULTS: Forty-three patients (35...

BACKGROUND: Vitamin D is suggested to reduce cardiovascular risk. HYPOTHESIS: Circulating levels of plasma lipids and other cardiovascular risk factors may differ between statin-treated patients with different vitamin D status. METHODS: We studied 3 age- and weight-matched groups of men with elevated low-density lipoprotein cholesterol (LDL-C) levels: vitamin D-naïve men with vitamin D insufficiency (group A, n = 18), men with vitamin D deficiency/insufficiency effectively treated with vitamin D preparations (group B, n = 16), and vitamin D-naïve men with normal vitamin D status (group C, n = 16)...

BACKGROUND: Micronutrient deficiencies occur in morbidly obese patients. The aim of this study was to assess vitamin deficiencies prior to bariatric surgery including vitamin K about which there is little data in this population. METHODS: A prospective assessment of 118 consecutive patients was performed. Clinical allied with haematological and biochemical variables were measured. Micronutrients measured included vitamins K1 , PIVKA-II (protein-induced in vitamin K absence factor II), vitamin D, vitamin B12 (holotranscobalamin), iron, transferrin and folate...

BACKGROUND: Statins are the treatment of choice for dyslipidemia, primarily lowering elevated LDL-C levels and reducing the occurrence of major cardiovascular events. In June 2011, the Food and Drug Administration issued a warning regarding the use of high-dose simvastatin 80 mg and its risk of myopathy. OBJECTIVE: The incidence of myalgia, myopathy, and rhabdomyolysis was analyzed in a veteran population prescribed simvastatin 80 mg. Risk factors for myalgia were examined and compared with the results of recently published studies...

AIMS: To examine use and changes of medication in the three years before start of chronic renal replacement therapy (RRT) among patients with type 1 diabetes, and the association between predialytic medication and survival on RRT. METHODS: We recorded medication of 496 patients with type 1 diabetes before and after start of RRT in 2000-2006 and followed up until death or end of 2009. Data were retrieved from the Finnish Registry for Kidney Diseases and from the FinDM diabetes database...

Treatment goals for patients with CKD are often unrealized for many reasons, but support by nurse practitioners may improve risk factor levels in these patients. Here, we analyzed renal endpoints of the Multifactorial Approach and Superior Treatment Efficacy in Renal Patients with the Aid of Nurse Practitioners (MASTERPLAN) study after extended follow-up to determine whether strict implementation of current CKD guidelines through the aid of nurse practitioners improves renal outcome. In total, 788 patients with moderate to severe CKD were randomized to receive nurse practitioner support added to physician care (intervention group) or physician care alone (control group)...

Chronic kidney disease (CKD) is a worldwide health problem. The disease is most often progressive of nature with a high impact on patients and society. It is increasingly recognized that CKD can be detected in the early stages and should be managed as early as possible. Treatment of the cause, but in particular control of the main risk markers, such as high blood pressure, glucose and albuminuria, has been instrumental in delaying the progression to end-stage renal disease (ESRD). However, despite the state of the art therapy, the absolute risk of renal and cardiovascular morbidity and mortality in CKD patients remains devastatingly high...

Diabetic nephropathy (DN) is the leading cause of end-stage kidney disease worldwide. However, current treatments remain suboptimal. Many factors, such as genetic and nongenetic promoters, hypertension, hyperglycemia, the accumulation of advanced glycation end products (AGEs), dyslipidemia, and albuminuria/proteinuria itself, influence the progression of this disease. It is important to determine the molecular mechanisms and treatment of this disease. The development of diabetes results in the formation of AGEs, oxidative stress, and the activation of the renin-angiotensin-aldosterone system (RAAS) within the kidney, which promotes progressive inflammation and fibrosis, leading to DN and declining renal function...

BACKGROUND: Vitamin D deficiency is nowadays considered as a potential cardiovascular and renal risk factor. We tested the hypotheses that vitamin D deficiency impairs the endothelial function of renal vasculature and whether vitamin D levels and endothelial function can be improved by the treatment with statins. METHODS: In a double-blind, randomized study of 31 hypercholesterolemic patients with vitamin D insufficiency (<30 ng/ml) were randomly assigned to rosuvastatin (10 mg/d) and placebo for 6 weeks...

BACKGROUND: This post hoc nested case-control analysis of the TNT study was designed to investigate whether baseline vitamin D level is a significant predictor of cardiovascular risk among statin-treated patients and whether changes in vitamin D after treatment with atorvastatin are associated with improved cardiovascular outcomes. METHODS: A total of 10,001 patients with stable coronary heart disease were randomized to atorvastatin 80 or 10 mg for a median of 4...
