Rheumatoid Arthritis Complications Explained
This question asks to identify the complications associated with Rheumatoid Arthritis (RA). RA is a chronic autoimmune disease primarily affecting joints, but it can also lead to systemic complications.
Evaluating Potential Complications
Let's examine each listed item:
- 1. Peripheral entrapment neuropathies: RA commonly causes inflammation and swelling around joints and nerves. This can compress nerves, leading to conditions like carpal tunnel syndrome, which is a type of peripheral entrapment neuropathy. This is a recognized complication.
- 2. Subluxation of the cervical spine at the atlanto-axial joint: Inflammation in RA can affect the ligaments and bones of the upper cervical spine, specifically the C1 (atlas) and C2 (axis) vertebrae. This can lead to instability and subluxation (partial dislocation), posing a risk of spinal cord compression. This is a known complication.
- 3. Primary amyloidosis: While chronic inflammation in RA can sometimes lead to secondary amyloidosis (AA type), primary amyloidosis (AL type) is not typically considered a direct complication of RA itself.
- 4. Lymphoma: Patients with RA have an increased risk of developing certain types of lymphoma, particularly non-Hodgkin lymphoma. This association is linked to chronic inflammation and potentially some RA treatments. This is a recognized complication.
Conclusion on RA Complications
Based on the analysis, peripheral entrapment neuropathies (1), subluxation of the cervical spine (2), and lymphoma (4) are established complications of Rheumatoid Arthritis. Primary amyloidosis is less directly associated.
Therefore, the correct combination is 1, 2, and 4.
