Insights
Severe hypocalcemia in a child with chronic kidney disease caused seizures and hypovitaminosis D. Prolonged intravenous calcium gluconate therapy was required to normalize ionized calcium levels.
Area of Science:
- Pediatric Nephrology
- Clinical Medicine
- Biochemistry
Background:
- Hypocalcemia is a common laboratory and clinical abnormality in pediatric patients.
- It can present with neurological symptoms like seizures and irritability, and cardiac dysfunction.
- Chronic kidney disease (CKD) is a significant risk factor for metabolic disturbances, including hypocalcemia.
Purpose of the Study:
- To report a unique case of severe hypocalcemia in a pediatric patient with CKD.
- To highlight the clinical manifestations and management of this condition.
- To emphasize the importance of monitoring calcium levels in children with CKD.
Main Methods:
- Case report of an eleven-year-old male child.
- Clinical presentation, laboratory investigations (including calcium, vitamin D levels, EEG, ECG), and treatment were analyzed.
- Management involved prolonged intravenous calcium gluconate therapy.
Main Results:
- The patient presented with severe hypocalcemia, tonic-clonic seizures, and hypovitaminosis D.
- Electroencephalogram (EEG) and electrocardiography (ECG) were normal, ruling out significant neurological or cardiac electrical abnormalities.
- Intravenous calcium gluconate therapy was effective in correcting ionized calcium levels.
Conclusions:
- Severe hypocalcemia can be a presenting manifestation of CKD in children, leading to significant neurological complications.
- Prompt and adequate calcium replacement is crucial for managing hypocalcemic seizures.
- This case underscores the importance of comprehensive metabolic evaluation in pediatric CKD patients.
Abstract:
Hypocalcemia is a laboratory and clinical abnormality that is observed especially in neonates and paediatric patients. Laboratory hypocalcaemia is often asymptomatic but it can manifest as central nervous system irritability, paraesthesia, tetany (i.e. contraction of hands, arms, feet, larynx, bronchioles), seizures, and even psychiatric changes in children. Cardiac function may also be impaired because of poor muscle contractility. We report a unique case of an eleven year old male child who presented with chronic kidney disease associated with severe hypocalcemia, tonic-clonic seizures, hypovitaminosis D but normal electroencephalogram and electrocardiography. The child required prolonged intravenous calcium gluconate therapy to correct his ionised calcium levels.
