Clinical Practice in the Prevention, Diagnosis and Treatment of Vitamin D Deficiency: A Central and Eastern European Expert Consensus Statement.
Study Goal
The researchers aimed to provide consensus recommendations for diagnosing and treating vitamin D deficiency in adults, addressing heterogeneity in existing guidelines.
Results Summary
The study recommends vitamin D supplementation doses of 800–2000 IU/day for maintenance and higher doses (e.g., 6000 IU/day) for rapid correction of deficiency, targeting serum 25(OH)D levels of 30–50 ng/mL. Testing is suggested for certain risk groups, but general screening is discouraged.
Population
Adults, particularly those in risk groups (e.g., patients with malabsorption syndromes).
Effective Dosage
800–2000 IU/day for maintenance; 6000 IU/day for initial 4–12 weeks in deficiency cases.
Duration
Maintenance dose ongoing; higher doses for 4–12 weeks initially.
Interactions
None mentioned
| Intervention | Direction | Endpoint | Population | Dosage | Impact | Claim # |
|---|---|---|---|---|---|---|
vitamin D supplementation | increase | vitamin D status | adults | - | ensure a sufficient vitamin D status | #1 |
vitamin D supplementation dose of 800 to 2000 international units (IU) per day | increase | vitamin D status | adults | 800 to 2000 IU per day | recommended | #2 |
higher vitamin D doses (e.g., 6000 IU per day) | decrease | vitamin D deficiency | - | 6000 IU per day | may be used for rapid correction | #3 |
higher vitamin D doses (e.g., 6000 IU per day) | decrease | vitamin D deficiency | - | 4 to 12 weeks | used for the first 4 to 12 weeks of treatment | #4 |
maintenance dose of 800 to 2000 IU per day | increase | vitamin D status | - | 800 to 2000 IU per day | continuing after initial treatment | #5 |
treatment | neutral | treatment success | certain risk groups (e.g., patients with malabsorption syndromes) | 6 to 12 weeks | evaluated after at least 6 to 12 weeks | #6 |
treatment | increase | serum 25(OH)D | certain risk groups (e.g., patients with malabsorption syndromes) | 30 to 50 ng/mL (75 to 125 nmol/L) | target concentrations | #7 |
Vitamin D deficiency has a high worldwide prevalence, but actions to improve this public health problem are challenged by the heterogeneity of nutritional and clinical vitamin D guidelines, with respect to the diagnosis and treatment of vitamin D deficiency. We aimed to address this issue by providing respective recommendations for adults, developed by a European expert panel, using the Delphi method to reach consensus. Increasing the awareness of vitamin D deficiency and efforts to harmonize vitamin D guidelines should be pursued. We argue against a general screening for vitamin D deficiency but suggest 25-hydroxyvitamin D (25(OH)D) testing in certain risk groups. We recommend a vitamin D supplementation dose of 800 to 2000 international units (IU) per day for adults who want to ensure a sufficient vitamin D status. These doses are also recommended for the treatment of vitamin D deficiency, but higher vitamin D doses (e.g., 6000 IU per day) may be used for the first 4 to 12 weeks of treatment if a rapid correction of vitamin D deficiency is clinically indicated before continuing, with a maintenance dose of 800 to 2000 IU per day. Treatment success may be evaluated after at least 6 to 12 weeks in certain risk groups (e.g., patients with malabsorption syndromes) by measurement of serum 25(OH)D, with the aim to target concentrations of 30 to 50 ng/mL (75 to 125 nmol/L).
