Currently a level of at least 30 ng/ml 25(OH D is considered as sufficient, values between 29 and 20 ng/ml as insufficiency, levels less than 20 ng/ml as deficiency and levels below 7 ng/ml as severe deficiency., - When we planned this study, only data on the vitamin D status of special cohorts were available, e.g., patients with osteoporosis, or with CVD.
It includes terms such as insufficiency, inadequate level, sub-optimal level and hypovitaminosis D and may result in subclinical conditions with chronic latent manifestations, the most recognized of which is osteoporosis.
In this cohort 11.5% showed signs of exocrine pancreatic insufficiency (elastase level < 200 μg/g stool) and 5.1% severe insufficiency (elastase level < 100 μg/g stool).
Bleeding (P <.001), elevated white blood cell count (P <.029), fever (P <.001), and renal insufficiency (creatinine level > 1.5; P <.056) were the only variables statistically significant in predicting graft failure or limb loss.
A review of all patients at the Emory University Hospital with renal insufficiency (creatinine level > or = 1.8) and concomitant atherosclerotic aortic and renovascular disease was undertaken.
Among healthy elderly patients in Argentina, Oliveri et al. found prevalence between 52%and87%7% of vitamin D insufficiency (serum level below 50 nmol/L) in the winter depending on the latitude [ 17].
A confirmed HUS case was defined as occurring in a patient with a clear history of acute diarrhea who showed the following signs: hemolytic anemia with microangiopathic changes, renal insufficiency (creatinine level >1.0 mg/dL in a child <13 years of age or >1.5 mg/dL in an adult, or >50% increase over baseline), and thrombocytopenia (platelet count <150,000/μL).
Indicators of severe pre-eclampsia on admission to the ICU included a sustained BP of 160/110 mmHg or more, proteinuria 4+ on qualitative assessment, oliguria (< 20 30 ml/hour), renal insufficiency (creatinine level >1.3 mg/dl), elevated liver enzymes, low platelet count (<100,000/μl), positive testing for hemolysis, epigastric pain, headache, visual disturbances and seizures.
For serum creatinine, participants with renal insufficiency (creatinine level >114.9 μmol/l (1.3 mg/dl)) were at highest risk of HMA compared with those who had normal creatinine levels (<88.4 μmol/l (1.0 mg/dl); HR 1.66, 95% CI 1.25 to 2.19), and participants with creatinine levels between 88.4 and 114.9 μmol/l inclusive were also at higher risk (HR 1.21, 95% CI 1.02 to 1.43).
Some studies conducted in Taiwan and Asia have shown nearly half of healthy, middle-aged and elderly women had vitamin D inadequacy, nearly one-third of adults with frailty syndrome had vitamin D insufficiency [ 19, 20] and inadequacy levels are more common in some Asian countries than in other regions [ 21].
