Mercury toxicity: a family case report

Area of Science:

• Environmental Health
• Toxicology
• Clinical Case Studies

Background:

• Environmental pollution poses risks through toxic substance exposure.
• Presents a unique case of liquid mercury poisoning in five family members.
• Affected individuals ranged from 20 to 54 years old.

Purpose of the Study:

• To report a rare instance of acute mercury poisoning within a single family.
• To illustrate the diverse and severe clinical manifestations of mercury toxicity.
• To emphasize the importance of considering heavy metal exposure in complex medical cases.

Main Methods:

• Detailed clinical presentation and laboratory findings of five family members exposed to liquid mercury.
• Case 1: Presented with pneumonia, neutropenia, anemia, and died from acute respiratory distress syndrome (ARDS).
• Cases 2 & 3: Exhibited bicytopenia and toxic peripheral neuropathy. Cases 4 & 5: Presented with fatigue, headache, and elevated blood mercury levels.

Main Results:

• Case 1 experienced rapid deterioration, succumbing to ARDS within four days.
• Hematological abnormalities included significant leukopenia and thrombocytopenia.
• Neurological symptoms such as toxic peripheral neuropathy were observed in multiple cases.
• Elevated blood mercury levels confirmed poisoning in all affected individuals.

Conclusions:

• Heavy metal exposure, though infrequent, must be considered in patients with multi-systemic symptoms.
• Mercury poisoning can present with a wide array of symptoms affecting cardiovascular, respiratory, and neurological systems.
• This report underscores the severity of mercury poisoning and its potential impact on entire families.
