Clinical Predictive Values in Botulism: A 10-year Survey.

Area of Science:

• Environmental Health
• Infectious Diseases
• Clinical Medicine

Background:

• Botulism presents a significant, albeit uncommon, public health threat in Iran, often occurring in periodic outbreaks.
• The lethality of botulism underscores its importance in environmental health surveillance and management.

Purpose of the Study:

• To retrospectively analyze a decade of foodborne botulism cases.
• To identify potential predictive factors for patient outcomes and mortality.

Main Methods:

• Retrospective analysis of medical records of 61 foodborne botulism patients admitted to Imam Reza Hospital from 2005-2015.
• Utilized logistic regression to identify independent significant factors affecting mortality.

Main Results:

• Canned beans consumption correlated with increased ICU admission and length of stay.
• Dizziness and diplopia required higher antitoxin doses; ptosis increased dysphagia risk.
• Mechanical ventilation, dyspnea, general weakness, and lack of consciousness were significant predictors of mortality.

Conclusions:

• Clinical assessment of signs and symptoms upon patient arrival is crucial for effective emergency management.
• Early treatment did not significantly improve outcomes in this cohort, highlighting the importance of timely diagnosis and supportive care.
