Background: the association between sarcopenia and treatment outcomes in inflammatory bowel disease (IBD) is currently a subject of controversy.
Methods: a systematic search was performed of PubMed, Embase, Web of Science, and the Cochrane Library for studies published until April 2023. The quality assessment of each included study was performed using the Newcastle-Ottawa
Scale.
Results: seventeen studies were included with 2,895 IBD patients. Sarcopenia exhibited an increased risk of treatment failure (OR = 2.00, 95 % CI: 1.43-2.79) and notably increased the need for surgery (OR = 1.54, 95 % CI: 1.06-2.23) as opposed to a pharmacologic treatment plan change (OR = 1.19, 95 % CI: 0.71-2.01) among IBD patients. However, no significant association was found between sarcopenia and treatment failure in corticosteroid (OR = 1.21, 95 % CI: 0.55-2.64) or biologic agent (OR = 1.65, 95 % CI: 0.93-2.92) cohorts. Sarcopenia was also linked to elevated treatment failure risks in patients with Crohn’s disease (OR = 1.82, 95 % CI:1.15-2.90) and those diagnosed with ulcerative colitis (OR = 2.55, 95 % CI: 1.05-6.21), spanning both Asian (OR = 1.88, 95 % CI: 1.29-2.74) and non-Asian regions (OR = 2.17, 95 % CI: 1.48-3.18).
Conclusions: sarcopenia was considered as a novel marker for use in clinical practice to predict treatment failure, specifically, the need for surgery in IBD patients. This distinct cohort necessitates clinical attention and tailored care strategies.

Background: A remission induction therapy of granulocyte and monocyte adsorptive apheresis (GMA) with Adacolumn was given to patients with active Crohn’s disease (CD). However, establishing an appropriate treatment strategy for GMA in patients with active CD remains unclear. Methods: This multicenter retrospective cohort study encompassed patients with CD who underwent GMA in seven independent institutions in Japan from January 2010 to March 2023. All clinical data were obtained from medical records. This study aimed to evaluate the clinical efficacy, safety, and subsequent clinical progression after GMA in patients with CD. Result: This study enrolled 173 patients with active inflammatory bowel disease who underwent GMA with Adacolumn, and among them, 16 patients with CD with mild to moderate disease activity were analyzed. Concomitant medication, including steroids, immunomodulators, and biologics, was used in 93.7% of all cases. The overall remission and response rates were 25.0% and 68.8%, respectively. The response rate between groups concerning the frequency and total GMA sessions revealed no significant difference. Six (37.5%) patients experienced adverse events (AEs). All AEs were related to the trouble in blood access and recovered soon without any sequelae. Regarding the factors associated with response to GMA, the responder group had a significantly longer disease duration (336 vs 44 months, p = 0.036) and exhibited a relatively lower rate of intestinal strictures and a median score of a simple endoscopic score for CD (SES-CD) (9.1 vs 60 %, p = 0.063 and 10 vs 21.5, p = 0.091, respectively). Further, all patients responding to GMA received biologics that were continuously used before and after GMA. Furthermore, 36.4% of patients remained on the same biologics 52 weeks after GMA. Notably, all patients who continued the same biologics had previously experienced a loss of response to anti-tumor necrosis factor-α agent. Conclusion: Therefore, GMA may exhibit heightened effectiveness in patients with moderately active CD without severe endoscopic activity. Moreover, it represents a potential novel therapeutic option for refractory CD, particularly with insufficient response to biologics.

Background: Granulocyte and monocyte adsorptive apheresis (GMA) with Adacolumn has been used as a remission induction therapy for patients with active ulcerative colitis (UC). Herein, we investigated the influence of concomitant medications in the remission induction of GMA in patients with active UC. Methods: This multicenter retrospective cohort study included patients with UC underwent GMA in five independent institutions in Japan from January 2011 to July 2021. Factors including concomitant medications associated with clinical remission (CR) were analyzed statistically. Result: A total of 133 patients were included. Seventy-four patients achieved a CR after GMA. The multivariable analysis revealed that concomitant medication with 5-aminosalicylic acid, Mayo endoscopic subscore (MES), and concomitant medication with immunosuppressors (IMs) remained as predictors of CR after GMA. In the subgroup analysis in patients with MES of 2, concomitant medication with IMs was demonstrated as a significant negative factor of CR after GMA (P = .042, OR 0.354). Seventy-four patients who achieved CR after GMA were followed up for 52 weeks. In the multivariable analysis, the maintenance therapy with IMs was demonstrated as a significant positive factor of sustained CR up to 52 weeks (P = .038, OR 2.214). Furthermore, the rate of sustained CR in patients with biologics and IMs was significantly higher than that in patients with biologics only (P = .002). Conclusion: GMA was more effective for patients with active UC that relapsed under treatment without IMs. Furthermore, the addition of IMs should be considered in patients on maintenance therapy with biologics after GMA.

Apheresis is a term for a group of extracorporeal treatments in which blood is separated into its components, with some components being discarded and replaced or subsequently modified. The replacement fluids/cells or modified components, along with the remainder of the blood, are then returned to the patient. These procedures can alter the immune system, both humoral and cellular, and have been used to treat a variety of common and uncommon immunologic diseases beginning in the late 1950s. The basic background information important for understanding those apheresis procedures used to treat immunologic disorders as well as the important patient considerations are discussed. A synopsis of immunologic diseases treated with apheresis, based upon the American Society for Apheresis Guidelines for the use of apheresis in clinical practice, is provided including treatment schedules and “dosing,” patient evaluation and laboratory monitoring, and the proposed mechanism of action. Unique considerations for each treatment, such as their effects on patient management and concurrent therapies, are also discussed. Apheresis is a group of related therapies that can effectively treat several immunologic diseases with a growing but still a limited base of published evidence.
