Sarcoidosis, a systemic granulomatous disease, affects diverse populations globally. Research suggests environmental and lifestyle factors like particulate matter, microbes, nicotine, and obesity may contribute to its development.
Area of Science:
- Immunology
- Epidemiology
- Environmental Health
Background:
- Sarcoidosis is a multisystem granulomatous disease with varied clinical presentations, often termed 'the great mimicker.'
- Its global prevalence affects all demographics, yet no specific cause has been identified.
- The most affected organs suggest environmental and lifestyle influences.
Purpose of the Study:
- To review the current epidemiology of sarcoidosis.
- To discuss non-genetic risk factors implicated in sarcoidosis development.
- To stimulate further research into environmental and lifestyle contributions.
Main Methods:
- Literature review of sarcoidosis epidemiology.
- Analysis of environmental and lifestyle risk factors.
- Synthesis of current research on non-genetic contributors.
Main Results:
- Sarcoidosis exhibits a worldwide distribution across all sexes, races, ethnicities, and ages.
- Key environmental and lifestyle factors include particulate matter, microorganisms, nicotine use, and obesity.
- No single causal agent has been identified to date.
Conclusions:
- Environmental and lifestyle factors are significant areas for future sarcoidosis research.
- Understanding these non-genetic risks may provide crucial insights into disease mechanisms.
- Further investigation is needed to elucidate the precise roles of these factors.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
