Introduction/Objectives:
Inflammatory vasculitis (IV) is characterized by blood vessel inflammation, leading to vessel damage and potential organ failure. This study aimed to identify the risk factors and comorbidities in adults with IV.
Methods:
A retrospective review of adult patients receiving outpatient care was conducted. Variables were compared between IV and non-IV (NoIV) groups.
Results:
Among 1500 patients, 626 (41.7%) had IV. Patients in the IV group were significantly older (IV = 66.5 ± 18.8 vs NoIV = 52.9 ± 18.4 years; P < .001) and women (IV = 67.7 vs NoIV = 48.0%; P < .001). IV group had a lower prevalence of patients of White race, and higher prevalences of use of tobacco and recreational drugs. Higher frequencies of associations of comorbid medical conditions were noted in the IV group compared to NoIV group, such as hypertension (50.7 vs 29.0%; P < .001), DM (19.4 vs 10.4%; P < .001), CKD (12.1 vs 3.7%; P < .001), CAD (12.1 vs 6.2%; P < .001), CHF (5.8 vs 2.0%; P < .001), PAD (2.4 vs 0.8%; P = .013), COPD (7.8 vs 1.8%; P < .001), pulmonary fibrosis (2.4 vs 0.1%; P < .001), osteoporosis (10.4 vs 1.9%; P < .001), osteoarthritis (12.0 vs 7.1%; P = .001), GERD (21.8 vs 13.2%; P < .001), depression (14.1 vs 7.9%; P < .001), hypothyroidism (14.2 vs 8.2%; P < .001), anemia (16.9 vs 5.0%; P < .001), seizure disorder (3.0 vs 0.9%; P < .001), cancer (13.7 vs 8.5%; P = .001), asthma (15.3 vs 6.7%; P < .001), atrial fibrillation (9.6 vs 4.7%; P < .001), CVA (7.0 vs 2.5%; P < .001), SLE (2.9 vs 0.5%; P < .001), and rheumatoid arthritis (5.0 vs 0.8%; P < .001). There were significantly greater odds of IV with increasing age per year (OR 1.030, 95% CI 1.022-1.039; P < .001), recreational drug use (OR 1.953, 95% CI 1.150-3.318; P < .013), hypertension (OR 1.590, 95% CI 1.155-2.188; P = .004), DM (OR 1.621, 95% CI 1.080-2.434; P = .020), osteoarthritis-osteoporosis (OR 1.496, 95% CI 1.020-2.193; P = .039), cardiac disorders (OR 1.543, 95% CI 1.065-2.236; P = .022), pulmonary disorders (OR 3.173, 95% CI 1.663-6.054; P < .001), and rheumatological disorders (OR 3.589, 95% CI 1.780-7.236; P < .001).
Conclusion:
IV is associated with older age, female sex, non-White race, tobacco use, recreational drug use, hypertension, DM, cardiovascular disorders (CAD, CHF, PAD, CVA), pulmonary disorders (COPD, asthma, pulmonary fibrosis), osteoporosis, osteoarthritis, SLE, and rheumatoid arthritis.

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.

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...
