Acute pancreatitis in a multi-ethnic population

Area of Science:

• Gastroenterology
• Epidemiology
• Public Health

Background:

• Limited data exists on ethnic variations in acute pancreatitis within Asian populations.
• Understanding these differences is crucial for targeted healthcare interventions.

Purpose of the Study:

• To investigate demographic, etiologic, and clinical differences in acute pancreatitis across Malaysia's major ethnic groups: Malays, Chinese, and Indians.
• To identify ethnic-specific risk factors and outcomes for acute pancreatitis.

Main Methods:

• A retrospective review of 133 consecutive acute pancreatitis patients admitted between January 1994 and July 1999.
• Analysis of patient demographics, identified etiologic factors (alcohol, gallstones, idiopathic), and clinical outcomes, stratified by ethnicity.

Main Results:

• Indians showed a higher association with alcohol-induced pancreatitis (73.3%), while Malays and Chinese predominantly had gallstone pancreatitis.
• A significant proportion of Malay patients (60.5%) had unidentified etiologic factors.
• Alcohol-related pancreatitis was more common in males, and gallstone pancreatitis in females.
• Severe pancreatitis occurred in 25% of cases with no significant ethnic or etiologic differences in severity.
• Overall mortality was 7.5%, with multi-organ failure as the primary cause of death.

Conclusions:

• Significant ethnic variations exist in the etiology and clinical characteristics of acute pancreatitis in Malaysia.
• Sociocultural factors likely contribute to these observed ethnic differences.
• Further research is needed to elucidate the specific mechanisms driving these disparities.
