Abstract
ABO incompatibility has long been considered an absolute contraindication for kidney transplantation. However, with the increasing number of patients with ESRD in recent years, ABO-incompatible kidney transplantation (ABOi-KT) has expanded the types of donors by crossing the blood group barrier through preoperative desensitization therapy. At present, the desensitization protocols consist of removal of preexisting ABO blood group antibody titers and prevention of ABO blood group antibody return. Studies have suggested similar patient and graft survival among ABOi-KT and ABOc-KT recipients. In this review, we will summarize the effective desensitization regimens of ABOi-KT, aiming to explore effective ways to improve the success rate and the long-term survival rate of ABOi-KT recipients.

Plasma exchange in the intensive care unit: a narrative review. Intensive Care Med 2022; 48:1382-1396. [PMID: 35960275 PMCID: PMC9372988 DOI: 10.1007/s00134-022-06793-z] [Citation(s) in RCA: 25] [Impact Index Per Article: 12.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2022] [Accepted: 06/20/2022] [Indexed: 02/04/2023]
Abstract
In this narrative review, we discuss the relevant issues of therapeutic plasma exchange (TPE) in critically ill patients. For many conditions, the optimal indication, device type, frequency, duration, type of replacement fluid and criteria for stopping TPE are uncertain. TPE is a potentially lifesaving but also invasive procedure with risk of adverse events and complications and requires close monitoring by experienced teams. In the intensive care unit (ICU), the indications for TPE can be divided into (1) absolute, well-established, and evidence-based, for which TPE is recognized as first-line therapy, (2) relative, for which TPE is a recognized second-line treatment (alone or combined) and (3) rescue therapy, where TPE is used with a limited or theoretical evidence base. New indications are emerging and ongoing knowledge gaps, notably regarding the use of TPE during critical illness, support the establishment of a TPE registry dedicated to intensive care medicine.

J Clin Apher 2021; 36:766-774. [PMID: 34339059 DOI: 10.1002/jca.21928] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2021] [Revised: 07/09/2021] [Accepted: 07/14/2021] [Indexed: 11/08/2022]
Abstract
BACKGROUND Double-filtration plasmapheresis (DFPP), a selective therapeutic apheresis, can deplete pathogenic antibodies/substances, but also important coagulation factors. AIM To determine if the use of a separator filter with different characteristics (CascadefloEC-50 W) as compared to the reference filter (PlasmafloOP-08 W) is as efficient in terms of immunoglobulin loss, but can reduce coagulation factor losses and have similar tolerability. PATIENTS/METHODS This is a single-center prospective study including 14 patients divided into two groups (7 each): that is, group1 = CascadefloEC-50 W and group2 = PlasmafloOP-08 W. We measured immunoglobulins, lipid profiles, blood-cell counts, hemostasis (prothrombin time, activated partial thromboplastin time), coagulation factors, and natural anticoagulants at before and after the first DFPP-session. RESULTS In group 1, the loss of coagulation factors was significantly reduced as compared to group 2 for proteins with a molecular weight of >150 kDa: there was, respectively, an average decrease of 70% vs 31% for fibrinogen (P = 0.004), 66% vs 21% for factor V (P = 2.16e-07), 60% vs 32% for factor XI (P = 6.96e-06), 75% vs 17% for XIII-antigen (P = 0.0002), and 47% vs 0% for VWF-antigen(P = 0.02). The decrease in post-session IgG was, on average, 45% in group 1 and 50% in group 2 (P = 0.13). Those results remained significant even when adjusted to the treated-plasma volume and the pre-DFPP factor values. CONCLUSION DFPP, using a CascadefloEC-50W as a first-filter, reduces efficiently IgGs similarly to PlasmafloOP-08W but spares clotting factors.

Treatment of antibody-mediated rejection with double-filtration plasmapheresis, low dose IVIg plus rituximab after kidney transplantation. J Clin Apher 2021; 36:584-594. [PMID: 33783868 DOI: 10.1002/jca.21897] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/08/2021] [Revised: 03/05/2021] [Accepted: 03/16/2021] [Indexed: 12/19/2022]
Abstract
Antibody-mediated rejection (ABMR) at early or late post-transplantation remains challenging. We performed a single-center single-arm study where four cases of acute ABMR and nine cases of chronic active ABMR (defined by Banff classification) were treated with double-filtration plasmapheresis (two cycles of three consecutive daily sessions with a 4-day gap between). At the end of the third and sixth DFPP sessions, the patients received rituximab 375 mg/m2 . After a median follow-up of 1078 (61-1676) days, kidney-allograft survival was 50%. Before DFPP/rituximab therapy, the median donor-specific alloantibody (DSA) mean fluorescence intensity (MFI) was 9160 (4000-15 400); 45 days (D45) later it had significantly decreased to 7375 (215-18 100) (P = .018). In addition, at one-year (Y1) post-therapy, MFI had decreased further, that is, 4060 (400-7850) (P = .001). In two patients, DSA MFIs decreased and remained below 2000. The slope of estimated glomerular-filtration rate within the 6 months preceding intervention was -1.18 mL/min/month and remained unchanged at -1.29 mL/min/month within the year after intervention. Proteinuria remained unchanged. Baseline Banff scores on repeat allograft biopsies (post-therapy D45, Y1) did not show any improvement. Side-effects were mild to moderate. We conclude that the combined DFPP/rituximab significantly decreased DSAs in ABMR kidney-transplant recipients but did not improve renal function or renal histology at 1-year follow-up.
