From the Guidelines
Mucoid change is a pathological process characterized by the accumulation of mucin within tissues, resulting in a gelatinous or viscous appearance, and is commonly observed in degenerative disorders of connective tissue, such as chronic bronchitis, where it is associated with an increase in the size and number of submucosal glands and an increase in the number of goblet cells on the surface epithelium 1.
Pathogenesis of Mucoid Change
The pathogenesis of mucoid change in chronic bronchitis involves the production of excessive amounts of mucopolysaccharides, which are complex carbohydrates that normally form part of the extracellular matrix. This process is mediated by the increase in the size and number of submucosal glands and the increase in the number of goblet cells on the surface epithelium, leading to the formation of a continuous sheet or blanket of mucus lining the airways instead of the discreet deposits of mucus seen in normal airways 1.
Clinical Implications
Mucoid change is an important factor in the development of chronic bronchitis, as it leads to the accumulation of mucus in the airways, which can cause coughing, wheezing, and shortness of breath. The presence of mucoid change is also associated with an increased risk of exacerbations and a poorer quality of life in patients with chronic bronchitis 1.
Diagnosis and Treatment
The diagnosis of mucoid change is typically made based on the presence of symptoms such as coughing and wheezing, and the presence of mucus in the airways. Treatment of mucoid change typically involves the use of bronchodilators and corticosteroids to reduce inflammation and improve lung function, as well as the use of mucolytic agents to break down and clear mucus from the airways 1.

From the Research
Mucoid Change
- Mucoid change is not directly mentioned in the provided studies, however, mucositis is a related condition that is discussed in several studies 2, 3, 4.
- Mucositis is a common complication of anticancer therapy that can affect up to 90% of certain populations of patients with cancer 2.
- The management of mucositis is an important aspect of cancer care, and several guidelines have been developed to help healthcare professionals assess, prevent, and manage mucositis induced by chemotherapy, radiotherapy, and targeted therapy 2, 4.
- Oral mucosal diseases, including mucositis, can have a significant impact on patients' quality of life and ability to tolerate treatment 3, 5.
- While the provided studies do not specifically discuss mucoid change, they do highlight the importance of managing oral mucosal diseases and mucositis in patients with cancer 2, 3, 4, 5.
