ABSTRACT

AIM: Hypocalcaemia evaluation of the clinical, biochemical and radiological features of 91 infants with rickets who presented as hypocalcaemic convulsions. SUBJECTS AND METHODS: Ninety-one hypocalcaemic infants who were brought to hospital with convulsion and diag-nosed with rickets related to vitamin D deficiency according to their clinical, biochemical and radio-logical features were retrospectively reviewed. RESULTS: Mean values of the laboratory data were as follows: calcium 5.55 ± 0.79 mg/dL, phosphorus 4.77 ± 1.66 mg/dL, alkaline phosphatase 1525.5 ± 925.4 U/L and parathormone 256.8 ± 158.3 pg/mL. Serum 25-OH vitamin D levels were below normal (< 20 ng/mL) in 37 infants. CONCLUSION: Vitamin D deficiency should be considered in infants presenting with hypocalcaemia. To avoid complications such as convulsions, clinicians should give vitamin D supplementation to such infants.


OBJETIVO: Evaluación hipocalcémica de los aspectos clínicos, bioquímicos y radiológicos de 91 lactantes con raquitismo, que presentaron convulsiones por hipocalcemia. PACIENTES Y MÉTODOS: Noventa y un lactantes hipocalcémicos llevados al hospital con convulsiones y a quienes se les diagnosticó raquitismo asociado a la deficiencia de vitamina D de acuerdo con sus características, bioquímicas y radiológicas, fueron revisados retrospectivamente. RESULTADOS: Los valores medios de los datos de laboratorio fueron los siguientes: calcio 5.55 ± 0.79 mg/dL, fósforo 4.77 ± 1.66 mg/dL, fosfatasa alcalina 1525.5 ± 925.4 U/L, y paratohormona 256.8± 158.3 pg/mL. Los niveles séricos de la vitamina 25 (OH) D estuvieron por debajo de lo normal en 37 lactantes (< 20 ng/mL). CONCLUSIÓN: La deficiencia de vitamina D debe considerarse en los infantes que se presentan con hipocalcemia. A fin de evitar complicaciones tales como convulsiones, se les debe dar suplementos de vitamina D.
