Medical Intelligence & Overview
Reiter's disease, also known as reactive arthritis, is a type of inflammatory condition that typically develops following an infection elsewhere in the body. This condition often affects the joints, eyes, and urinary or genital systems, leading to a range of symptoms that can significantly impact daily activities. Recognized under the ICD-10 code M02.3, Reiter's disease primarily involves inflammation that occurs as a reaction to an infection, rather than direct infection of the joints or tissues.
Causes & Symptoms
Clinical Causes: Previous bacterial infections, especially in the gastrointestinal or urinary tract, commonly caused by bacteria such as Salmonella, Shigella, Yersinia, or Chlamydia. Genetic predisposition, with a higher likelihood in individuals carrying the HLA-B27 gene. Environmental factors and immune response variations may also contribute to the development of the disease.
Key Symptoms: Joint pain and swelling, especially in the knees, ankles, and feet. Conjunctivitis or inflammation of the eyes, which may cause redness, pain, and sensitivity to light. Urinary problems, including pain during urination or urethritis. Skin rashes, particularly on the soles of the feet, palms of the hands, or other parts of the body. Mouth ulcers or sore patches in the mouth. General symptoms like fever, fatigue, and malaise.
Diagnostic & Treatment
Diagnosis Path: Diagnosis of Reiter's disease involves a combination of medical history, physical examination, and laboratory tests. Healthcare providers may look for recent infections or symptoms and perform tests such as blood work to identify inflammation, cultures to detect bacteria, and joint fluid analysis. The presence of HLA-B27 gene testing can support the diagnosis but is not definitive on its own. No single test confirms Reiter's disease; instead, diagnosis is based on clinical criteria and exclusion of other conditions.
Treatment Protocols: Management of Reiter's disease aims to relieve symptoms and address the underlying infection when possible. Common approaches include:
