Do catecholaminergic Gene Polymorphisms Are Associated with GI Symptoms and Morphological Brain Changes in Irritable Bowel Syndrome?
In IBS, catecholaminergic SNPs are associated with symptom severity and morphological changes in brain regions concerned with sensory processing and modulation and affect regulation. Thus, certain adrenergic receptor genes may facilitate or worsen IBS symptoms.
In patients with ILD, dyspnea is associated with depression score, functional status, and pulmonary function. These results suggest that attention to depression and functional status is important in these patients and that treatment directed at these comorbidities may improve dyspnea and quality of life.
