Summary

This study identified twenty Saudi Arabian sarcoidosis cases, often misdiagnosed as tuberculosis or lymphoma. Sarcoidosis in Saudi Arabia presents with severe symptoms and frequent eye involvement, necessitating further epidemiological research.

Area of Science:

  • Pulmonary Medicine
  • Immunology
  • Epidemiology

Background:

  • Sarcoidosis is considered rare in Saudi Arabia.
  • Misdiagnosis as tuberculosis or lymphoma is common.
  • Limited data exists on sarcoidosis epidemiology in the Saudi population.

Purpose of the Study:

  • To report cases of sarcoidosis in native Saudis.
  • To describe the clinical presentation and diagnostic challenges.
  • To investigate treatment outcomes and disease progression.

Main Methods:

  • Retrospective case series of twenty native Saudi sarcoidosis patients.
  • Review of clinical presentations, diagnostic methods, and treatment.
  • Correlation analysis between symptoms and Angiotensin Converting Enzyme (ACE) levels.

Main Results:

  • Twenty sarcoidosis cases identified, with 55% initially referred for suspected tuberculosis or lymphoma.
  • Severe constitutional symptoms (52%), eye involvement (35%), and Stage II chest film changes (70%) were noted.
  • Negative Mantoux test (95%), positive non-caseating granulomata (95%), and a correlation between symptoms and ACE levels (p < 0.034).

Conclusions:

  • Sarcoidosis may be underdiagnosed in Saudi Arabia.
  • Clinical presentation shows similarities to Western patterns but with distinct features.
  • Further epidemiological studies are crucial to understand sarcoidosis prevalence and characteristics in native Saudis.
