Coexistence of granulomatosis with polyangiitis (GPA) and Crohn's disease or multiorgan manifestation of the same disease?

Saddle Nose Deformity in a Patient With Crohn's Disease

Crohn's disease is a chronic inflammatory disorder of the gastrointestinal tract, frequently presenting with extraintestinal manifestations. Granulomatosis with polyangiitis is a systemic vasculitis primarily affecting the respiratory tract and kidneys. Extraintestinal Crohn's disease and granulomatosis with polyangiitis may have similar clinical presentations and, in rare occurrences, can coexist. This case report highlights the diagnostic and therapeutic complexities of this uncommon overlap syndrome.

Gastrointestinal Hemorrhage With Gastritis and Pancolitis as the Sole Presentation for Granulomatosis With Polyangiitis Flare

Granulomatosis with polyangiitis (GPA), previously known as Wegener granulomatosis, is a rare small vessel vasculitis affecting mainly Whites. The prevalence of GPA in the United States is estimated to be 3 of 100,000 individuals. Classically, GPA affects upper airways, lungs, and kidneys, with the upper airways being the most common site. Occasionally, other organs affected by GPA include eyes, skin, joints, and the nervous system. The gastrointestinal system is rarely affected; however, some cases have been reported. In this case report, we present a patient with hemorrhagic gastritis and pancolitis consistent with GPA and discuss features from the literature of gastrointestinal manifestations in patients with GPA.

Gastrointestinal symptoms as first remarkable signs of ANCA-associated granulomatosis with polyangiitis: a case report and reviews

Background

Systemic vasculitis associated with antineutrophil cytoplasmic autoantibodies (ANCA) have an extremely wide variety of symptoms, therefore the fast and proper diagnosis is difficult to establish even for experienced physicians. Gastrointestinal manifestations in ANCA-associated granulomatosis with polyangiitis (GPA) may be present, however, severe, life-threatening complications (such as perforations) are rare.

Case presentation

A case of an 18-year-old male patient is presented, where gastrointestinal symptoms (abdominal pain, vomiting, diarrhoea) were the first remarkable signs of GPA. The initial diagnosis of inflammatory bowel disease delayed the administration of proper immunosuppressive therapy, which might have contributed to the rare and life-threatening complication of arterial duodenal bleeding with perforation. Our systematic review of the literature found only a few case reports where gastrointestinal symptoms were the first signs of GPA, however, this entity might be more frequent if physicians would think of this possibility more often.

Conclusions

Gastrointestinal bleeding is a rare but potential lethal complication of vasculitis. Consequently, we recommend investigating the patients diagnosed with GPA for gastrointestinal bleeding during the treatment.

Orbital Inflammatory Complications of Crohn's Disease: A Rare Case Series

Orbital inflammatory disease is a rare ophthalmic manifestation of Crohn's disease. Inflammation is characteristically nonspecific, involving one or multiple structures of the orbit. Mechanisms of disease and optimal methods of treatment are poorly understood. The aim of this report is to present 3 cases of orbital involvement in Crohn's disease. A retrospective case note review of patients with orbital inflammatory disease and Crohn's disease was performed at our academic center to determine the clinical, imaging, and histopathologic features of this condition and its relationship to intestinal Crohn's disease. Three patients were identified with orbital inflammatory manifestations complicating Crohn's disease. All patients described were women with active intestinal disease and had a history of treatment with immunosuppressive therapies. Similarities were observed in clinical presentations with variance noted in radiologic and histopathologic findings. In all cases, symptoms improved with oral corticosteroids or nonsteroidal drugs in combination with anti-tumor necrosis factor agents. Inflammatory bowel disease-related orbital complications are rare but potentially vision-threatening. It is important to consider mimics of orbital inflammatory disease such as systemic inflammatory disease, malignancy, congenital malformations, infection, and trauma when formulating a comprehensive differential diagnosis. Therapeutic intervention is directed toward preservation of vision and orbital function and reducing the acute inflammatory process. Corticosteroids are typically the initial treatment of choice for moderate-to-severe disease, although several classes of immunomodulatory agents have been variably useful in treating this condition. Heightened awareness and close cooperation between gastroenterologists and ophthalmologists are mandatory.
