The spectrum of respiratory diseases associated with ulcerative colitis. The respiratory diseases associated with ulcerative colitis have recently been recognized, and principally affect the bronchi. Both chronic bronchitis and bronchiectasis may develop after many years, some of the patients having already undergone colectomy. Chronic bronchitis is characterized by cough and chronic mucopurulent sputum, and these symptoms may be exacerbated during acute flare-ups of ulcerative colitis. The bronchial lesions are inflammatory and can be reversed by corticosteroid therapy. Bronchiectasis produces similar symptoms, but has distinctive radiological features. Corticosteroids may sometimes reduce the symptoms, but they have no effect on the bronchial lesions. Salicylazosulfapyridine might be responsible for hypersensitivity lung diseases with eosinophilia, but the drug does not seem to be involved in the genesis of these bronchial manifestations. There have been occasional reports of other respiratory diseases associated with ulcerative colitis, including obliterative bronchiolitis, isolated and asymptomatic airflow obstruction, inflammatory tracheal stenosis, pulmonary vasculitis, pleurisy and pleuropericarditis, chronic pneumonia and interstitial fibrosis which may be diffuse or localized to the apices.

Symptoms and physical findings may indicate the severity of inflammatory disease of the colon, but detailed history taking is needed to limit the wide spectrum of possible causes. Infectious causes should be ruled out before other disease is assumed to be present. No single test is sufficient to diagnose ulcerative colitis or Crohn's disease. Laboratory testing, histologic assessment, endoscopy, radiology, and bowel studies are often necessary in differential diagnosis. Because of the systemic nature of colitis, manifestations in the musculoskeletal, ocular, dermatologic, hepatobiliary, and other systems may occur and provide clues. Treatment depends on the type and severity of disease. Sulfasalazine (Azulfidine), sulfa-free 5-aminosalicylic acid compounds, and corticosteroids are mainstays of treatment of ulcerative colitis and Crohn's disease. Supportive care and judicious use of antimicrobial therapy are usually effective in colitis due to bacterial, parasitic, and sexually transmitted infections and are useful for symptoms caused by colonic ischemia and vasculitis. Colitis resulting from radiation therapy may present several years after the procedure and can be difficult to diagnose and treat. In many cases of inflammatory colon disease, especially chronic conditions, consultation with a gastroenterologist is highly recommended.

Sulfasalazine (SSZ) can induce serological and clinical autoimmune reactions but the occurrence of SSZ-related Wegener's granulomatosis (WG) has not been reported before. We describe two patients with rheumatoid factor (RF)-positive rheumatoid arthritis (RA) who developed biopsy-proven WG with serious organ involvement during SSZ therapy. The pathogenetic mechanism that explains the relationship between SSZ and the occurrence of a de novo anti-neutrophil cytoplasmic antibody (ANCA)-related vasculitis or a flare is discussed. We propose that WG can be a rare complication of SSZ therapy and that this, like other autoimmune adverse events of this drug, is mediated by SSZ-induced apoptosis.
