Leukocytaphersis (or leukapheresis) is a therapeutic procedure in which white blood cells (WBCs) are selectively removed from the patient’s circulation. The procedure is performed for the treatment of hyperleukocytosis most commonly in the setting of leukemia. Adsorptive cytapheresis utilizes apheresis in association with a medical device to selectively extract leukocyte subsets (activated monocytes and granulocytes) from the patient’s circulation. Adsorptive cytapheresis has been utilized for the treatment of multiple inflammatory conditions including inflammatory bowel disease, systemic lupus erythematosus, psoriasis, Behçet’s disease, and rheumatoid arthritis.

Introduction: Ulcerative colitis (UC) is a chronic inflammatory bowel disorder (IBD) with periods of relapse and remission. Current advancements in clinical research have led to the development of more refined and effective medical therapy for UC.

Summary of the evidence: Traditional therapeutic agents such as 5-aminosalicylates (5-ASAs), sulfasalazine (SASP), corticosteroids, and immunomodulatory drugs have remained the gold standard for decades. However, their novel formulations and dosage regimens have changed their sequences in the medical management of UC. Several other novel drugs are in the final phases of clinical development or have recently received regulatory approval designed to target specific mechanisms involved in the inflammatory cascade for UC.

GMA has shown its efficacy in mild to moderate UC and refractory UC (steroid-dependent UC or biologic/immunologic resistant UC or lost their response to biologics) for remission induction.

Conclusions: This narrative review sought to provide a comprehensive knowledge of the potential benefits of standard and emerging therapies, including novel formulations, new chemical entities, and novel therapeutic approaches in managing UC. Keywords: Ulcerative colitis, 5- Aminosalicylic acid, sulfasalazine, corticosteroids, biologics, immunomodulators, novel formulations.

Inflammatory Bowel Disease (IBD) is a hallmark of leukocyte infiltration, followed by the release of cytokines and interleukins. Disease progression to Ulcerative Colitis (UC) or Crohn’s Disease (CD) remained largely incurable. The genetic and environmental factors disrupt enteral bacteria in the gut, which hampers the intestinal repairing capability of damaged mucosa. Commonly practiced pharmacological therapies include 5-aminosalicylic acid with corticosteroids and tumor necrosis factor (TNF)-α. New interventions such as CDP571 and TNF-blocking RDP58 report the loss of patient response. This review discusses the non-pharmacologic selective granulocyte-monocyte-apheresis (GMA) and leukocytapheresis (LCAP) that have been proposed as treatment modalities that reduce mortality. GMA, an extracorporeal vein-to-vein technique, presents a strong safety profile case for its use as a viable therapeutic option compared to GMA’s conventional medication safety profile. GMA reported minimal to no side effects in the pediatric population and pregnant women. Numerous studies report the efficacious nature of GMA in UC patients, whereas data on CD patients is insufficient. Its benefits outweigh the risks and are emerging as a favored non-pharmacological treatment option. On the contrary, LCAP uses a general extracorporeal treatment that entraps leukocytes and suppresses cytokine release. It has been deemed more efficacious than conventional drug treatments, the former causing better disease remission, and maintenance. Patients with UC/CD secondary to complications have responded well to the treatment. Side effects of the procedure have remained mild to moderate, and there is little evidence of any severe adverse event occurring in most age groups. LCAP decreases the dependence on steroids and immunosuppressive therapies for IBD. The review will discuss the role of GMA and LCAP.

Many biological disease-modifying antirheumatic drugs (bDMARDs) and targeted synthetic DMARDs (tsDMARDs) are currently available as treatment options for rheumatoid arthritis (RA), but a subset of RA patients shows inadequate responses to any of these DMARDs. This phenomenon, which we call super-resistance, is becoming a serious concern. In this study, I present two cases of super-resistant RA in which patients failed to respond to treatment with bDMARDs of any class as well as to tsDMARD therapy with tofacitinib. In these cases, leukocytapheresis (LCAP), a treatment that removes overabundant leukocytes from the body, rapidly induced low disease activity and made patients subsequently responsive to previously ineffective DMARDs. My experience with the present cases suggests that LCAP is worth considering as an alternative therapeutic option for the management of RA patients with super-resistance to DMARD therapies.

Single-needle (SN) apheresis may be safe and effective and may reduce patient burden during UC treatment. Nevertheless, further comparative studies are needed.

While leukocyte-derived proinflammatory cytokines have been validated as successful targets in IBD treatment, so should leukocytes themselves be considered as treatment options. As activated leukocytes migrate into the bowel wall and drive the inflammatory cascade in IBD patients, their depletion by apheresis techniques are considered beneficial to control the mucosal inflammation.

Leukapheresis, consisting in either granulomonocyte apheresis or leukocyte apheresis, are cell-based therapies with promising results in some patient categories and with a good safety profile. They have been studied as an alternative in patients with steroid toxicity, dependency or refractoriness, or in the event of contraindications to conventional therapy. Most of the early studies were not controlled, with only a few randomized controlled trials providing quality data on their efficacy. Future studies should be designed to look at selection of IBD patients who benefit most and safely from this non-pharmacological therapy.

Inflammatory bowel diseases (IBD) have become a major focus for gastroenterologists worldwide, with the increasing incidence and complexity of cases, which pose therapeutic challenges. Currently available approaches fail in controlling the disease activity in a significant proportion of patients and some of the therapies are associated with significant adverse events. Although new molecules are on the horizon and treatment strategies have been optimized, novel therapeutic tools are much needed in IBD for patients who fail to attain control of the disease. Apheresis is now a common non-pharmacological therapeutic modality used in several pathologies, IBD also. In the current review, we summarize currently available evidence with respect to selective apheresis in IBD.
