IBD in the Elderly: Management Challenges and Therapeutic Considerations.

PURPOSE OF REVIEW: Elderly patients with inflammatory bowel disease (IBD) are increasing in prevalence as our population ages and the incidence of IBD increases. The purpose of this review is to describe the management challenges in elderly IBD patients, including comorbid conditions and therapeutic considerations unique to the elderly population. RECENT FINDINGS: The elderly experience coexisting comorbidities that complicate IBD management. The disease course and potential side effects of treatments can impact the elderly IBD patient differently than younger IBD patients. The duration for colorectal cancer surveillance (CRC) also remains controversial and should be individualized to determine when discontinuation is appropriate. Given greater safety considerations in the elderly IBD population, treatment targets and management goals require a more personalized approach in the elderly, taking into account coexisting comorbidities, inflammatory burden, and functional limitations.

Evaluating tofacitinib citrate in the treatment of moderate-to-severe active ulcerative colitis: design, development and positioning of therapy.

The etiology of ulcerative colitis (UC) is complex and involves a host of genetic, epigenetic and environmental factors. Over the last thirty years, signaling pathways like the Janus kinase (JAK) signaling pathway have been implicated in its pathogenesis. Pharmacologic blockade of this pathway is available through several small molecule inhibitors, including tofacitinib. Tofacitinib is an orally administered pan-JAK inhibitor that was first approved by the Food and Drug Administration (FDA) for use in rheumatologic disorders such as rheumatoid arthritis and psoriatic arthritis. The FDA approved its use in moderate-to-severe active ulcerative colitis in 2018. The aim of this review will be to discuss the role of tofacitinib in ulcerative colitis. We will discuss the role of JAK-STAT signaling, clinical data available for tofacitinib, and the safety profile for this therapy. Tofacitinib's place in the UC management algorithm is currently being debated. This effective oral therapy is poised to be a mainstay of UC therapeutics. This review will highlight the key clinical features and detail the UC experience to date.

Natural history and clinical outcomes in patients with portal vein thrombosis by etiology: A retrospective cohort study.

BACKGROUND: Portal vein thrombosis (PVT) is an unusual-site thrombosis commonly encountered in patients with malignancies, cirrhosis, and acute abdominal inflammatory conditions (AIC). Current recommendations suggest that anticoagulation may improve recanalization rates but there is limited information on venous thromboembolism (VTE) recurrence rates and whether the etiologies of PVT respond similarly with anticoagulation. OBJECTIVE: To characterize the natural clinical course and outcomes of patients diagnosed with PVT based on etiology. PATIENTS/METHODS: Patients with a diagnosis of PVT between 2005 and 2015 who were followed for at least one year and had revised imaging at 12 months ±â€¯3 months were identified. Comorbidities, demographics, anticoagulation choice and clinical outcomes including VTE recurrence, cavernous transformation, PVT recanalization, progression and mortality were obtained. RESULTS: Of 698 patients diagnosed with PVT, 85 patients were evaluable according to criteria: 54 had cirrhosis (63.5%), 15 malignancy (17.6%) and 16 AIC (18.8%). Mean age was 55.6 ±â€¯13.1 years. At presentation, 40% patients were symptomatic and 29.4% received anticoagulation. Patients with AIC were anticoagulated more frequently compared to those with malignancy or cirrhosis (87.5% vs. 33.3% vs. 11.1%). Overall, patients with cirrhosis had lower rates of PVT progression (0% vs. 13.3%, p = 0.02) and patients with AIC had higher rates of cavernous transformation compared to cirrhosis or malignancy-associated PVT (31.3% vs. 7.4% vs. 0%, p = 002). Among untreated patients, those with malignancy had significantly higher rates of VTE recurrence and PVT progression than patients with cirrhosis (20% vs. 4.2% and 20% vs. 0%). CONCLUSIONS: The natural course of PVT differs among etiologies. In the absence of anticoagulation, patients with malignancy are more prone to VTE recurrence and PVT progression compared to patients with cirrhosis. Given the high rate of VTE recurrence at 12 months in patients with malignancy-associated PVT, anticoagulation should be considered for this group.

Severe Ileocolonic Crohn's Disease Flare Associated with Fecal Microbiota Transplantation Requiring Diverting Ileostomy.

Patients with inflammatory bowel disease (IBD) are at increased risk of developing Clostridium difficile infection (CDI). Fecal microbiota transplantation (FMT) is an effective therapy with a high success rate in preventing recurrent CDI. However, patients with IBD have decreased response to FMT for recurrent CDI, with several reports also suggesting potential IBD flare post-FMT. We present a case of mild ileocolonic Crohn's disease in a patient treated with FMT for recurrent CDI who subsequently developed severe steroid-refractory flare requiring surgical intervention 1 week post-FMT. Greater understanding of risk factors associated with post-FMT IBD flare is indicated.

Rapidly growing Mycobacterium infections after cosmetic surgery in medical tourists: the Bronx experience and a review of the literature.

BACKGROUND: Medical tourism is increasingly popular for elective cosmetic surgical procedures. However, medical tourism has been accompanied by reports of post-surgical infections due to rapidly growing mycobacteria (RGM). The authors' experience working with patients with RGM infections who have returned to the USA after traveling abroad for cosmetic surgical procedures is described here. METHODS: Patients who developed RGM infections after undergoing cosmetic surgeries abroad and who presented at the Montefiore Medical Center (Bronx, New York, USA) between August 2015 and June 2016 were identified. A review of patient medical records was performed. RESULTS: Four patients who presented with culture-proven RGM infections at the sites of recent cosmetic procedures were identified. All patients were treated with a combination of antibiotics and aggressive surgical treatment. CONCLUSIONS: This case series of RGM infections following recent cosmetic surgeries abroad highlights the risks of medical tourism. Close monitoring of affected patients by surgical and infectious disease specialties is necessary, as aggressive surgical debridement combined with appropriate antibiotic regimens is needed to achieve cure. Given the increasing reports of post-surgical RGM infections, consultants should have a low threshold for suspecting RGM, as rapid diagnosis may accelerate the initiation of targeted treatment and minimize morbidity.
