Introduction: The proportion of elderly patients with IBD is steadily increasing due to the aging population and improved survival. Patients in this age group present specificities in diagnosis and treatment, particularly regarding the use of biological agents, where immunosenescence, multimorbidity, and polypharmacy affect the precise assessment of benefit and risk. Aim: This systematic review, which was conducted in accordance with the PRISMA 2020 statement, aims to synthesize available data on the epidemiology, clinical characteristics, and therapeutic management of IBD in the elderly, with emphasis on the most recent data and practical guidelines for the use of biological therapies. Methods: A systematic search of PubMed, Scopus, and Embase was conducted. A total of 40 studies were included, comprising 5 randomized controlled trials, 15 prospective cohort studies, and 20 retrospective observational studies. Eligible studies included randomized controlled trials, observational cohort studies, and population-based analyses. Given substantial clinical and methodological heterogeneity, findings were synthesized narratively. Data on demographics, disease phenotype, comorbidities, and treatment outcomes were extracted and analyzed. In addition, a narrative synthesis of major randomized trials of biologic therapies, recent guidelines, and data from prospective studies and patient registries was performed with a focus on safety and real-world outcomes in the elderly. Risk of bias was assessed using the Newcastle–Ottawa Scale (NOS) and the Cochrane Risk of Bias tool. Results: The majority of included studies (85%) were found to have a low to moderate risk of bias, providing a reliable basis for the synthesis. Data show an increasing incidence of IBD in the elderly, often with a milder clinical course and a higher ratio of UC to CD. Multimorbidity and polypharmacy are significant challenges that increase the risk of adverse events. Although classic therapies remain effective, in many cases, a lower threshold is required to initiate advanced therapies, such as biologic agents. Anti-tumor necrosis factor (anti-TNF) agents, as well as biologics with alternative mechanisms of action such as vedolizumab (α4β7 integrin antagonist) and ustekinumab (interleukin-12/23 inhibitor), represent key therapeutic options in elderly patients with IBD. These biologic factors have efficacy comparable to that in younger patients and are considered attractive options due to reduced systemic immunosuppression and favorable safety profiles. JAK inhibitors are a practical option but are associated with an increased thromboembolic risk and require careful patient selection. Older age is associated with higher absolute rates of serious infections, hospitalizations, and, in some series, mortality. Individualized decision-making, including frailty assessment, vaccination coverage, infection control, and dose adjustments based on renal and hepatic function, is essential for optimal care. Conclusions: IBD in the elderly is a distinct clinical entity with unique challenges in diagnosis and management. A multidisciplinary approach and individualized treatment strategies are essential to ensure the balance between disease control and minimizing the risks associated with comorbidity and polypharmacy. Further research, including specifically designed clinical trials, is needed to optimize treatment and outcomes in this unique patient group.

Background: The long-term clinical and laboratory results of a 33-year follow-up of a Greek family with abetalipoproteinemia (ABL) are described. Case Report: The patients (two brothers and their sister, aged 57, 49, and 62 years, respectively) are still alive, being under close surveillance. In two of the three patients, diarrhea appeared in early infancy, while in the third, it appeared during adolescence. CNS symptomatology worsened after the second decade of life. At the same time, night blindness appeared in the advanced stages of the disease, resulting in almost complete loss of vision in one of the male patients and severe impairment in the other. The diagnosis was based on the clinical picture, ophthalmological findings, serum lipid estimations, and presence of peripheral acanthocytosis. All patients exhibited typical serum lipidemic profile, ophthalmological findings, and acanthocytes in the peripheral blood. During the follow-up period, strict dietary modifications were applied, including the substitution of fat with medium-chain triglycerides (MCT oil). After 33 years since the initial diagnosis, all patients are alive without any sign of liver dysfunction despite continuous use of MCT oil. However, symptoms from the central nervous system and vision impairment worsened. Conclusion: The course of these patients suggests that the application of a modified diet, including MCT oil, along with close surveillance, could prolong the survival of patients without significant side effects from the liver.

Background: Ulcerative colitis (UC) and sarcoidosis are chronic inflammatory diseases that share immunological pathways but rarely coexist. The increasing use of biologic agents in inflammatory bowel disease (IBD) has raised concerns regarding paradoxical inflammatory manifestations, including sarcoidosis-like reactions. Case presentation: We report the case of a 63-year-old man with long-standing UC treated with vedolizumab who developed systemic sarcoidosis characterized by bilateral hilar lymphadenopathy, mediastinal and abdominal lymph node enlargement, pulmonary involvement, and erythema nodosum. Extensive diagnostic work-up, including imaging and histopathology, confirmed non-necrotizing granulomatous disease consistent with sarcoidosis, while alternative infectious, malignant, and drug-induced causes were excluded. Vedolizumab was temporarily discontinued, leading to UC relapse, and subsequently reintroduced with rapid clinical remission of UC. Discussion: Sarcoidosis remained clinically and radiologically stable despite vedolizumab re-initiation, suggesting a coincidental association rather than a direct causal relationship. This case highlights the diagnostic challenges and therapeutic dilemmas in patients with immune-mediated diseases receiving biologic therapy. Conclusion: The coexistence of UC and sarcoidosis during vedolizumab therapy is rare. Although causality cannot be established, our findings suggest that vedolizumab may be safely continued in selected patients under close multidisciplinary monitoring.
