Appendicitis in acquired immunodeficiency syndrome

Area of Science:

• Surgery
• Infectious Diseases
• Gastroenterology

Background:

• Surgical literature lacks data on common intra-abdominal diseases in patients with acquired immunodeficiency syndrome (AIDS).
• Existing research on appendicitis in AIDS patients is limited, with high perforation rates and diagnostic difficulties.
• Focus has been on AIDS-related intra-abdominal conditions, often requiring surgery only when complicated.

Purpose of the Study:

• To review appendicitis cases in patients with AIDS.
• To analyze diagnostic challenges and outcomes.
• To evaluate the utility of preoperative symptoms and signs in differentiating appendicitis types.

Main Methods:

• Literature review of appendicitis in AIDS patients (30 cases from 13 studies).
• Retrospective review of 28 patients with appendicitis and AIDS over 7 years from 4 urban hospitals.
• Analysis of preoperative symptoms, signs, diagnostic imaging, and surgical outcomes.

Main Results:

• Literature review showed a 40% perforation rate in appendicitis among AIDS patients.
• The 7-year hospital review reported no perioperative deaths and an 18% postoperative complication rate.
• 18% of patients had normal appendices with other pathologies; 30% had AIDS-related appendicitis.
• No preoperative symptom or sign reliably differentiated AIDS-related from non-AIDS-related appendicitis, except for diffuse vs. localized pain.

Conclusions:

• Appendicitis in AIDS patients often presents with diagnostic delays and errors.
• Advanced imaging (ultrasound, CT scans) and early surgical intervention are crucial.
• Aggressive diagnostic and therapeutic approaches are recommended for improved patient management.
