**Question:** In a patient with gouty arthritis, synovial fluid aspiration will show -
A. increased uric acid levels
B. normal uric acid levels
C. decreased uric acid levels
D. increased white blood cell count
**Core Concept:** Gout is a form of arthritis caused by the deposition of monosodium urate crystals in the joints, typically the toes, ankles, knees, and wrists. Synovial fluid aspiration is a diagnostic procedure that involves withdrawing synovial fluid from the affected joint to evaluate the fluid's composition and cellular content.
**Why the Correct Answer is Right:** In gouty arthritis, the primary cause of inflammation lies in the presence of monosodium urate crystals, which are formed when the blood uric acid levels are elevated. When synovial fluid is aspirated, it shows increased uric acid levels (option A), reflecting the elevated uric acid concentration in the blood.
**Why Each Wrong Option is Incorrect:**
B. Normal uric acid levels (option B) would be expected in non-gouty arthritic conditions where uric acid levels are not elevated, such as rheumatoid arthritis.
C. Decreased uric acid levels (option C) would be unusual in a gouty arthritis case, as elevated uric acid levels are the hallmark of this condition.
D. Increased white blood cell count (option D) can be seen in various inflammatory joint conditions, but it is not specific to gouty arthritis. Uric acid levels are more indicative of the diagnosis compared to white blood cell count.
**Clinical Pearl:** Uric acid levels are a crucial diagnostic test in gouty arthritis, as they directly correlate with the elevated uric acid levels in the blood, which is the primary cause of inflammation in this condition. Synovial fluid aspiration should be performed to confirm the diagnosis and rule out other joint inflammatory conditions.
