Appendicitis in the HIV Era: a South African perspective

Area of Science:

• Surgery
• Infectious Diseases
• Gastroenterology

Background:

• The clinical presentation and outcomes of appendicitis in Human Immunodeficiency Virus (HIV)-positive individuals are not well-documented in South Africa.
• Understanding these differences is crucial for optimizing surgical management and patient care.

Purpose of the Study:

• To compare surgical management, histopathology, and outcomes of appendicitis in HIV-positive versus HIV-negative patients.
• To investigate the specific impact of HIV status on appendicitis presentation and treatment in a South African setting.

Main Methods:

• Retrospective analysis of 50 patients who underwent appendicitis surgery at King Edward VIII Hospital, Durban, from January 2012 to December 2012.
• Patients were categorized into HIV-positive (n=14) and HIV-negative (n=36) groups.
• Comparison of surgical approaches, histopathological findings, complication rates, and length of hospital stay.

Main Results:

• HIV-positive patients showed a higher incidence of perforated appendicitis (50% vs. 25%) and a significantly greater rate of laparotomy (71% vs. 33%).
• Granulomatous inflammation of the appendix was exclusively observed in HIV-positive patients (n=3).
• No significant differences were found in complication rates or mean length of hospital stay between the two groups.

Conclusions:

• Perforated appendicitis and the need for laparotomy are more prevalent in HIV-positive patients in this South African cohort.
• While HIV status influences appendicitis severity and surgical approach, it did not significantly impact short-term outcomes like complications or hospital stay.
• Granulomatous inflammation is a distinct histopathological finding associated with appendicitis in HIV-positive individuals.
