Which of the following statements are true?
a) Aspiration pneumonia is common in patients with polymyositis
b) Pleural effusions are commonly seen in systemic sclerosis
c) There is a higher incidence of lymphocytic interstitial pneumonia in patients
with Sjogren’s syndrome
d) Relapsing polychondritis results in thickening of the tracheal wall on CT
e) Pulmonary’ involvement does not occur in CREST syndrome
The true statement among the options provided is:
c) There is a higher incidence of lymphocytic interstitial pneumonia in patients with Sjogren’s syndrome.
Explanation:
– Aspiration pneumonia can occur in patients with polymyositis due to impaired swallowing and respiratory muscle weakness, but it is not necessarily common.
– Pleural effusions are commonly seen in systemic sclerosis due to inflammation of the pleura and increased vascular permeability.
– Lymphocytic interstitial pneumonia is a common pulmonary manifestation of Sjogren’s syndrome, characterized by lymphocytic infiltration of the pulmonary interstitium.
– Relapsing polychondritis is a rare autoimmune disorder that primarily affects cartilaginous structures, such as the ears and nose, but it does not typically cause thickening of the tracheal wall on CT.
– Pulmonary involvement can occur in CREST syndrome (a variant of systemic sclerosis), including conditions like pulmonary arterial hypertension and interstitial lung disease.
Therefore, the only true statement is that there is a higher incidence of lymphocytic interstitial pneumonia in patients with Sjogren’s syndrome.
