An update of the effects of vitamins D and C in critical illness

Abstract: Many critically ill patients are vitamin D and vitamin C deficient and the current international guidelines state that hypovitaminoses should be compensated. However, uncertainty about optimal dosage, timing and indication exists in clinical routine, mainly due to the conflicting evidence. This narrative review discusses both micronutrients with regards to pathophysiology, clinical evidence of benefits, potential risks, and guideline recommendations. Evidence generated from the most recent clinical trials are … Show more

“…It has been widely remarked that urinary tract infections are a strong predictor of mortality and complications for stone surgery [31]. Other factors related to a poor clinical outcome in critical illness, such as vitamin D deficiency, are frequently found in lithiasic patients [32]. Therefore, our findings suggest a higher mortality in elderly patients influenced by a higher prevalence of urinary tract infections.…”

“…Furthermore, other comorbidity diseases have been pointed out as predictors of mortality in treated lithiasis patients, such as gender, body mass index, diabetes, cardiovascular diseases, and vitamin deficiency [29,31,32]. In this paper, age, diabetes mellitus, and hypertension have been shown to be mortality predictors both in univariate and multivariate analyses.…”

“…Maintenance of body calcium stores depends on dietary calcium intake, absorption from the gastrointestinal tract, and renal calcium excretion. PTH enhances distal tubular calcium reabsorption, independently of sodium, while proximal tubule calcium excretion is sodium dependent [12].…”

“…Critically ill patients are prone to reduced serum levels of vitamin C [12]. Whilst there have been no reports of the effect of vitamin C supplementation on bone health in critically ill patients, there has been significant interest on high-dose IV vitamin C particularly in sepsis.…”

“…68,70 Vitamin D insufficiency was associated with musculoskeletal disease, cognitive decline, cancers (breast, colon, prostate), cardiovascular disease, hypertension, dyslipidemia, autoimmune disease, kidney injury, infection, and mortality. [66][67][68][70][71][72]74,76,77 Vitamin D has many natural and synthetic analogs. The natural analogs of vitamin D mainly involves in human are vitamin D 2 (ergocalciferol) which found in plant and fungi, and vitamin D 3 (cholecalciferol).…”
