Abstract

Severe hypophosphatemia, serum phosphate concentration <0.32 mmol/L (<1.0 mg/dL), occurred in 8 of 68 (12%) of children with kwashiorkor within 48 hours of admission; 5 of 8 (63%) of these children died, compared with 13 of 60 (22%) children without severe hypophosphatemia (P <.02). Dermatosis and dehydration were significantly correlated with severe hypophosphatemia, but these clinical signs could not reliably predict fatal cases. Severe hypophosphatemia seems to be common and life-threatening in children with kwashiorkor in Malawi.
