[Epidemiological aspects of ankylosing spondylitis]

Area of Science:

• Rheumatology and immunology
• Epidemiology
• Genetics

Background:

• Ankylosing spondylitis is a chronic inflammatory disease primarily affecting the axial skeleton.
• Understanding its epidemiological characteristics is crucial for public health and clinical management.
• The role of human leukocyte antigen B27 (HLA-B27) has been extensively studied, but non-specific factors also contribute to disease risk.

Purpose of the Study:

• To present a concise overview of the epidemiological aspects of ankylosing spondylitis.
• To highlight key demographic and genetic factors associated with the disease.
• To identify and discuss both specific and non-specific risk factors influencing ankylosing spondylitis.

Main Methods:

• Review of existing epidemiological data on ankylosing spondylitis.
• Analysis of prevalence, incidence, and mortality rates.
• Description of non-specific risk factors including age, sex, familial clustering, and racial distribution.

Main Results:

• The study outlines the prevalence, incidence, and mortality rates of ankylosing spondylitis.
• Non-specific risk factors such as age, sex, familial clustering, and racial distribution are described.
• A notable absence of clearly defined specific risk factors for ankylosing spondylitis is reported.

Conclusions:

• Epidemiological data provide insights into the burden of ankylosing spondylitis.
• Non-specific factors play a role in the disease's occurrence and distribution.
• Further research is needed to identify specific etiological factors for ankylosing spondylitis.
