A 14-year-old female with no significant medical history presented with hypertensive urgency, in the setting of 4 to 6 weeks of diarrhea, abdominal pain, headaches, anemia, weight loss, and high blood pressures. Her evaluation revealed signs of a systemic inflammatory process that was most suspicious for inflammatory bowel disease. However, when her hypertension was evaluated with a renal Doppler ultrasound, there were signs of narrowing, stenosis, and hypoplasia that led to a diagnostic angiogram of the abdominal aorta. Full body positron emission tomography scan revealed multiple areas of stenosis and aortic thickening with enhancement compatible with Takayasu arteritis. She received prednisone, methotrexate, and infliximab with marked improvement in her clinical symptoms and inflammatory markers.

Tomography Scan

We describe a case of a 61-year-old man with a background of rheumatoid arthritis who presented to the emergency department with a single-reported episode of haemoptysis on the background of an upper respiratory tract infection. A CT scan revealed an incidental 40 mm mass in upper right lobe of the liver abutting the diaphragmatic surface. A subsequent positron emission tomography scan confirmed the mass and raised the possibility of another lesion in the liver raising the suspicion of malignancy. The case was complicated by the inability to perform a fine needle aspiration biopsy due to the mass’ proximity to the diaphragm. After discussion with the patient, it was decided to resect the affected liver segment. Histological analysis of the mass revealed localised necrotising granulomatous inflammation suggestive of a rheumatoid nodule, which is seldom reported in the literature.

Inflammatory Bowel

Inflammatory Bowel Disease (IBD) is a term used to describe a group of complex disorders of the gastrointestinal (GI) tract. IBDs include two main forms: Crohn’s Disease (CD) and Ulcerative Colitis (UC), which share similar clinical symptoms but differ in the anatomical distribution of the inflammatory lesions. The etiology of IBDs is undetermined. Several hypotheses suggest that Crohn’s Disease and Ulcerative Colitis result from an abnormal immune response against endogenous flora and luminal antigens in genetically susceptible individuals. While there is no cure for IBDs, most common treatments (medication and surgery) aim to reduce inflammation and help patients to achieve remission. There is growing evidence and focus on the prophylactic and therapeutic potential of probiotics in IBDs. Probiotics are live microorganisms that regulate the mucosal immune system, the gut microbiota and the production of active metabolites such as Short-Chain Fatty Acids (SCFAs). This review will focus on the role of intestinal dysbiosis in the immunopathogenesis of IBDs and understanding the health-promoting effects of probiotics and their metabolites.
