Summary

Dead Sea water intoxication causes severe hypercalcemia and hypermagnesemia, leading to serious health issues like respiratory distress and arrhythmias. High calcium levels predict mortality, suggesting early dialysis may be crucial.

Area of Science:

  • Toxicology
  • Environmental Health
  • Clinical Medicine

Background:

  • Dead Sea water ingestion can lead to unique toxicological profiles.
  • Severe hypercalcemia and hypermagnesemia are characteristic of this intoxication.
  • Clinical manifestations range from neurological disturbances to respiratory distress.

Purpose of the Study:

  • To describe the clinical features and outcomes of Dead Sea water intoxication.
  • To identify predictors of mortality in affected patients.
  • To evaluate the effectiveness of current treatment strategies.

Main Methods:

  • Retrospective analysis of 48 adult and 4 pediatric patients with Dead Sea water intoxication.
  • Clinical assessment, laboratory analysis of serum electrolytes (calcium, magnesium), and acid-base status.
  • Statistical analysis, including discriminant function analysis for mortality prediction.

Main Results:

  • 16 of 48 adult patients experienced severe clinical manifestations.
  • Common findings included tachyarrhythmias, conduction disturbances, and acidosis.
  • Serum calcium levels up to 28.8 mg/dL and magnesium up to 33 mg/dL were recorded.
  • Adult mortality rate was 19%, with serum calcium >15.5 mg/dL predicting mortality.
  • Supportive care, including forced diuresis, showed limited efficacy.

Conclusions:

  • Dead Sea water intoxication presents with severe hypercalcemia and hypermagnesemia, posing significant mortality risks.
  • Admission serum calcium concentration is a critical predictor of mortality.
  • Early dialysis should be considered for severe cases and warrants further investigation.
