Lead poisoning with encephalic and neuropathic involvement in a child: case report

Lead is a toxic substance in our environment that affects adults and children of all socioeconomic backgrounds, lead poisoning is one of the most common exposures that can cause inter alia significant neurological and functional damage in humans. Children are particularly vulnerable because of the effects of the toxicity on their developing nervous systems with potentially irreversible consequences. We report a case of severe lead poisoning encephalo-neuropathy in a 3-year-old girl, admitted for progressive paraplegia, swallowing disorders, and aphasia. A multitude of investigations undertaken could not explain her atypic symptoms, so anamnesis was redone in the sense of a toxic origin, we found a notion of pica, and a traditional herbalist father, so probably consumption of medications based on traditional medicine products. A venous blood lead level (BLL) was extremely elevated at 176.4 mu g/l. The child was treated with an oral chelator succimer (SUCCICAPTAL). During the two following months in the intensive care unit, the child showed progressive respiratory distress and worsening signs of the nervous system. Despite treatment and the use of lead chelators, the patient died due to septic shock. Lead is highly toxic even at very low exposure levels, at high levels of exposure, it can damage the reproductive organs, immune system, liver and kidneys. in children, it can affect neurocognitive and behavioral development that could be irreversible. Peripheral and central nervous system damage should be considered as a possible manifestation of lead poisoning.
