Key result
Among 14 children with dilated cardiomyopathy associated with Vitamin D deficiency, treatment resulted in 0% mortality and normalization of left ventricular ejection fraction in all but one patient.
Why the study?
The clinical profile, treatment details, intensive care needs, and long-term outcomes of children with dilated cardiomyopathy associated with vitamin D deficiency required description.
Observational (n=14)
No
Vitamin D deficiency is a potentially treatable and reversible cause of dilated cardiomyopathy in children, with excellent recovery of left ventricular function following supplementation.
May warrant vitamin D assessment in pediatric dilated cardiomyopathy; leaves open confirmation in prospective trials.
Aim: To describe the clinical profile, treatment details, intensive care needs, and long-term outcome of children with dilated cardiomyopathy (DCM) associated with Vitamin D deficiency (VDD). Materials and methods: Case records of 14 children with DCM associated with VDD [25(OH)D3 levels <20 ng/mL] admitted to the pediatric intensive care unit (PICU) of a tertiary care teaching hospital between January 2017 and December 2021 were retrospectively analyzed for clinical features, echocardiographic findings, treatment details, intensive care needs, and outcomes. Results: =10) were males. The common modes of presentation included respiratory distress or failure (78.6%), congestive cardiac failure (71.4%), cardiogenic shock (37.5%), and seizures and encephalopathy (14.3% each). The median (IQR) serum calcium was 8.7 (7-9.5) mg%, ionized calcium 0.7 (0.7-1.1) mmol/L, alkaline phosphatase 343 (316-415) IU/L, phosphate 3.5 (2.6-4.5) mg%, PTH 115 (66-228) pg/mL, and 25(OH)D3 5 (3-7) ng/mL. The median (IQR) left ventricular ejection fraction (LVEF) at admission was 22 (17-25)%. The treatment included intravenous calcium infusion (35.7%), vitamin D supplementation in all (57.1% parenteral and 42.9% oral), mechanical ventilation (35.7%), and vasoactive drugs (57.1%). There was no mortality. The median (IQR) duration of PICU and hospital stay was 76 (31-98) hours and 6 (4.7-10) days, respectively. Out of 14 children, 10 (71.4%) were followed-up till median (IQR) of 10 (7-58) months. All were asymptomatic and had normal LEVF (except one had residual moderate mitral regurgitation). Conclusion: Vitamin D deficiency is a potentially treatable and reversible cause of DCM in children. How to cite this article: .

Angurana et al. (2023) conducted an observational in Dilated cardiomyopathy associated with Vitamin D deficiency (n=14). Vitamin D deficiency was evaluated on Mortality and LVEF recovery. Among 14 children with dilated cardiomyopathy associated with Vitamin D deficiency, treatment resulted in 0% mortality and normalization of left ventricular ejection fraction in all but one patient.
