Sumario: | Lead poisoning, fairly common in the 20th century, has decreased drastically in the last decade. Severe lead poisoning in the form of encephalopathy has a fatality rate of 28% to 45% and neurological sequelae in about 82%. We present the management of a case of lead encephalopathy that recovered without any significant neurological sequelae in a resource-limited setting. A previously healthy seven-year-old boy presented with complaints of falling unconscious on the ground while playing, followed by multiple episodes of seizures, vomiting, and altered sensorium. The patient had pallor, Glasgow coma score of E2V3M3, with features of raised intracranial pressure. Lead poisoning was suspected as the patient had four months of exposure to a battery recycling factory. Management of seizures and raised intracranial pressure was done. X-ray long bones showed lead lines at the metaphysis. Blood lead levels were highly elevated (139.96 mcg/dL). Investigations revealed iron deficiency anemia, vitamin D deficiency, and renal tubular injury in the form of proteinuria. D-penicillamine with supplements was started due to unavailability of other chelating agents. Encephalopathy improved, but patient had psychiatric symptoms of hallucinations and delusions. On the 12th day, CaNa(2 )EDTA was started, which resulted in significant improvement in the psychiatric symptoms. The patient had near-complete recovery in another one month, the patient being able to read, write, recite and speak as the pre-illness state. In conclusion, lead poisoning remains a significant health problem even today. Early recognition and management are of paramount importance in its outcome. |
