Match the following patient clinical presentations to the most appropriate targeted laboratory autoantibody evaluation.
- A 32-year-old woman with a history of three consecutive unexplained spontaneous abortions at 12 weeks gestation and a recent unprovoked lower extremity deep vein thrombosis.Anti-beta-2-glycoprotein I and lupus anticoagulant testing
- A 48-year-old woman presenting with a 1-year history of tightening of the skin over her fingers, difficulty swallowing solid foods, and episodic blanching of her digits when exposed to cold.Anti-centromere antibody assay
- A 55-year-old man complaining of difficulty climbing stairs and combing his hair, accompanied by a violaceous periorbital rash and scaling papules on the dorsum of his hands.Anti-Jo-1 and anti-Mi-2 antibody testing
- A 42-year-old woman reporting a 6-month history of a persistent gritty sensation in her eyes, difficulty eating dry foods without liquids, and noticeable swelling in front of her ears.Anti-Ro/SSA and anti-La/SSB antibody testing
Cevap
Antiphospholipid syndrome pairs with lupus anticoagulant testing; CREST syndrome pairs with anti-centromere antibody; Dermatomyositis pairs with anti-Jo-1/anti-Mi-2 testing; Sjögren syndrome pairs with anti-Ro/anti-La testing.
Each clinical presentation describes a classic rheumatologic or autoimmune syndrome that requires specific laboratory testing for diagnostic confirmation. Recognizing the distinct constellation of signs and symptoms allows the clinician to avoid indiscriminate testing and instead order highly targeted serologic assays, such as anti-beta-2-glycoprotein I for hypercoagulable states or anti-centromere for scleroderma variants.
