Background/Aims:
Between 1996 and 1998 we investigated the occurrence of lung disorders in 82 patients with inflammatory bowel disease (30 patients with ulcerative colitis and 52 patients with Crohn's disease) and a control group of 60 subjects. The aim of our study was to determine the occurrence of pulmonary complications in patients with inflammatory bowel disease, to investigate whether ulcerative colitis or Crohn's disease are connected with a typical lung function disorder, with the inflammatory activity of the disease or if they depend on the presence of other extraintestinal manifestations.
Methodology:
We investigated the occurrence of lung disorders in terms of the following parameters: clinical pulmonary symptoms, chest radiography and pulmonary function tests (body plethysmography, pneumotachography, lung transfer capacity for carbon monoxide, and blood gas analysis).
Results:
Lung function abnormalities were significantly more frequent in patients with inflammatory bowel disease as compared to controls (p<0.001). There was no apparent correlation between these abnormalities and either bowel disease activity or drug administration (sulphasalazine, mesalazine).
Conclusions:
Despite the lack of radiological abnormalities, we identified a high incidence of pulmonary function abnormalities (suspicious of interstitial lung disorder) in patients with inflammatory bowel disease; 56.7% of patients with ulcerative colitis and 57.7% of patients with Crohn's disease had reduced lung transfer factor.

Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Symptoms of COPD can be classified as primary or systemic. Primary symptoms relate to reduced airflow, while systemic or extrapulmonary symptoms relate to COPD's broader impact on the body.

01:27Inflammatory 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...

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 transmural...
