Insights
Chronic glomitis, an inflammation of glomera, affects both carotid bodies and the glomus pulmonale. This study found evidence of chronic pulmonary glomitis occurring independently or with carotid glomitis in older adults.
Area of Science:
- Pathology
- Histology
- Immunology
Background:
- The carotid bodies are well-known sites for chronic glomitis.
- The occurrence of chronic glomitis in the glomus pulmonale is less understood.
Purpose of the Study:
- To investigate whether chronic glomitis is exclusive to carotid bodies or also present in the glomus pulmonale.
- To characterize the prevalence and associations of chronic glomitis in both locations.
Main Methods:
- Histological examination of carotid bodies and glomus pulmonale.
- Analysis of 50 consecutive necropsy subjects over 50 years of age.
Main Results:
- Lymphoid aggregates and plasma cell activity, indicative of chronic inflammation, were observed in the glomus pulmonale.
- Chronic pulmonary glomitis was found in association with, and independently of, chronic carotid glomitis.
- Chronic carotid glomitis affected 14% of subjects, predominantly women. Isolated pulmonary glomitis also showed female predominance.
Conclusions:
- Chronic glomitis is not confined to the carotid bodies and can affect the glomus pulmonale.
- This inflammatory process involves at least two components of the non-chromaffin paraganglionic system.
- The reasons for focal chronic inflammation in the glomus pulmonale remain unclear.
Abstract:
A histological study was made of the carotid bodies and glomus pulmonale in 50 consecutive subjects over the age of 50 years who came to necropsy to determine if chronic glomitis is confined to the carotid bodies or whether it also occurs in other glomera. Lymphoid aggregates and plasma cell activity were found in the glomus pulmonale just as they were in the carotid bodies. Chronic pulmonary glomitis sometimes occurred in association with chronic carotid glomitis and sometimes independently of this. The mean age of the affected subjects was 76 years in isolated pulmonary glomitis and 79 years in chronic carotid glomitis. Chronic carotid glomitis affected seven (14%) subjects and predominated in women (six to one). In the seven cases of isolated pulmonary glomitis women predominated five to two. Chronic glomitis seems to be a disease process which may affect at least two members of the non-chromaffin paraganglionic system, but it is not clear why focal chronic inflammation affects the glomus pulmonale of one person but not of another.
