Regarding rheumatic pleural effusion. what is not true
**Core Concept**
Rheumatic pleural effusion is a complication of rheumatic diseases such as rheumatoid arthritis, lupus, and scleroderma. It is characterized by the accumulation of fluid in the pleural space due to inflammation and fibrosis of the pleura. The underlying pathophysiology involves the interaction between immune cells, cytokines, and fibroblasts.
**Why the Correct Answer is Right**
The correct answer is related to the pathogenesis of rheumatic pleural effusion. Rheumatic pleural effusion is typically associated with an exudative type of pleural effusion, which is characterized by a high protein content and a high lactate dehydrogenase (LDH) level. This is due to the inflammation and fibrosis of the pleura, which leads to the accumulation of fluid rich in proteins and enzymes.
**Why Each Wrong Option is Incorrect**
**Option A:** Rheumatic pleural effusion is a common complication of rheumatic diseases. This statement is true, as rheumatic pleural effusion is a well-known complication of conditions such as rheumatoid arthritis and lupus.
**Option B:** Rheumatic pleural effusion is typically associated with a transudative type of pleural effusion. This statement is false, as rheumatic pleural effusion is typically associated with an exudative type of pleural effusion.
**Option C:** The treatment of rheumatic pleural effusion involves the use of corticosteroids. This statement is true, as corticosteroids are often used to treat the underlying inflammatory condition and reduce the production of pleural fluid.
**Option D:** Rheumatic pleural effusion is a rare complication of rheumatic diseases. This statement is false, as rheumatic pleural effusion is a relatively common complication of conditions such as rheumatoid arthritis and lupus.
**Clinical Pearl / High-Yield Fact**
One key point to remember is that rheumatic pleural effusion is often associated with an exudative type of pleural effusion, which can be distinguished from a transudative type by its high protein content and high LDH level. This is an important clinical correlation to remember when evaluating patients with pleural effusion.
**Correct Answer:** B.
