Background:
Type 2 inflammation has been described as a pathophysiological basis common to some diseases, such as atopic dermatitis (AD), chronic rhinosinusitis with nasal polyps, and asthma (CRSwNP).
Objective:
The present study used population-based prevalence in Catalonia to analyse the coexistence of type 2 inflammatory diseases in patients primarily diagnosed with the above mentioned conditions.
Results:
We found a high degree of coexistence of type 2 inflammatory diseases among these patients, with the prevalence being higher in the severe forms, except for AD. For the severe forms of primary diseases, the proportion of patients with coexisting type 2 inflammatory diseases (severe or non-severe) was 16.2% for AD, 19.8% for asthma, and a striking 62.4% for CRSwNP. This patient population has the highest proportion of coexisting type 2 inflammatory diseases, both severe (48.9%) and non-severe (13.5%).
Conclusion:
Our findings have significant implications for the management of patients with AD, asthma, and CRSwNP.

Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...
Inflammatory Bowel Disease I: Ulcerative Colitis
Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
