The Role of Therapeutic Plasma Exchange (TPE) in Multisystem Inflammatory Syndrome in Children (MIS-C). CHILDREN-BASEL 2021; 8:children8060498. [PMID: 34208141 PMCID: PMC8230791 DOI: 10.3390/children8060498] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/14/2021] [Revised: 05/31/2021] [Accepted: 06/09/2021] [Indexed: 12/27/2022]
Abstract
Multisystemic inflammatory syndrome in children (MIS-C) is a new potentially life-threatening disease that is related to coronavirus disease 2019 (COVID-19). The aim of this study is to reveal the clinical and laboratory results of MIS-C and the role of therapeutic plasma exchange (TPE) in its treatment. Clinical, laboratory and radiological characteristics of the patients who were admitted to the pediatric ward and pediatric intensive care unit (PICU) of a tertiary hospital with a diagnosis of MIS-C between April 2020 and March 2021 were included in the study. Forty-one patients were admitted to our hospital with a diagnosis of MIS-C. Twenty-one (51.2%) patients were admitted to the PICU. Six patients needed invasive mechanical ventilation (14.6%), 10 patients (24.4%) TPE and 3 patients (7.3%) needed extracorporeal membrane oxygenation (ECMO). The patients were grouped according to need for PICU admission (Group 1: no need for PICU, Group 2: need for PICU admission). Group 2 had significantly higher levels of C-reactive protein (CRP), alanine aminotransferase (ALT), ferritin, D-dimer, pro-B type natriuretic peptide (pro BNP) and lactate (p < 0.05). Hyponatremia found to be an independent risk factor for inpatient MIS-C in the PICU. We think that dynamic laboratory trending is beneficial in determining the need for PICU admission and TPE may be effective in critically ill patients.

Abstract
OBJECTIVE ABO mismatch between donor and recipient occurs in 40% of allogeneic hematopoietic stem cell transplantations (HCT). Different strategies have been described to reduce isohemagglutinins (IHA) before HCT. We describe the effect of selective ABO immunoadsorption (ABO IA) on erythrocyte transfusion rate and the development of post-transplant pure red cell aplasia (ptPRCA). METHODS 63 patients with major ABO incompatibility were retrospectively analyzed. Nine patients with major ABO incompatibility and high-IHA titer were treated by ABO IA before HCT. We analyzed the need for transfusion and the occurrence of ptPRCA. We compared the outcome with patients treated by other methods to reduce IHA. RESULTS In all nine patients treated by ABO IA, IHA decreased in a median four times. PtPRCA occurred in one patient. The median number of transfusions was 8 (range: 0-36) between d0 and d100. In 25 patients with high-IHA titer without treatment or treated by other methods to reduce IHA, the need for transfusions was comparable. No difference in the incidence of ptPRCA was observed. CONCLUSIONS Selective ABO IA is a feasible, safe, and effective method to reduce IHA before HCT in major ABO incompatibility. No effect on transfusion rate or ptPRCA compared to other strategies could be observed.

Abstract
BACKGROUND Crimean-Congo hemorrhagic fever (CCHF) is one of the common causes of tick-borne hemorrhagic infections. The study aims to report a case of a female patient with severe CCHF with pulmonary embolism. CASE REPORT A 61-year-old woman admitted to the emergency department with complaints of high fever, nausea, and weakness. The patient was dealing with animal husbandry and had a tick bite history. At laboratory findings, bicytopenia, abnormal liver function tests, and elevated coagulation parameters were observed. Real-time plymerase chain reaction confirmed the diagnosis of CCHF. Three sessions of plasmapheresis were performed due to continued fever and worsening in laboratory values. Pulmonary embolism was detected in computerized thorax tomography carried out due to respiratory alkalosis on the 6th day. She was successfully treated with supportive and anticoagulation therapy. CONCLUSION CCHF demonstrates different types of clinical presentations apart from fever and hemorrhage. Acute pulmonary embolism is a rare complication that has not been reported before.

Abstract
Although Crimean-Congo hemorrhagic fever (CCHF) is mild and self-limited in children, some patients may develop excessive bleeding, massive liver necrosis, and multiple organ failure associated with secondary hemophagocytic lymphohistiocytosis (HLH) induced by cytokine storm. Treatment of CCHF is mainly symptomatic and supportive. The efficacy of ribavirin, which is the only antiviral drug in the treatment of CCHF, remains controversial. Although therapeutic plasma exchange (TPE) has been shown to beneficial in small case series with primary and secondary HLH, there is no pediatric patient with HLH secondary to CCHF treated with TPE in the literature. In this report, we describe the first pediatric patient who was successfully recovered from HLH secondary to CCHF with ribavirin, intravenous immunoglobulin, and TPE.

Abstract
A 43‐year‐old man with a 23‐year history of type II diabetes presented with uncontrolled hyperglycemia with frequent episodes of ketoacidosis. He was diagnosed with exogenous insulin antibody syndrome, and received high‐dose methylprednisolone to treat insulin resistance. Ketoacidosis relapsed 2 years later, and the patient showed an incomplete response to glucocorticoids. We decided to administer therapeutic plasma exchange, which resulted in rapid lowering of the daily insulin requirement and improved glycemic control.

Abstract
BACKGROUND Criteria for selection of FFP blood type has not been clearly established and use of group AB plasma is preferred by numerous transplantation protocols. AIMS This study assesses the safety and efficacy of alternative group A or B plasma in ABO incompatible solid organ transplantation. MATERIALS & METHODS Alternative use of group A or B plasma (incompatible plasma) was inevitable during the shortage of group AB plasma. Experience from select number of patients during the period of extreme group AB plasma shortage is described. RESULTS The result of alternative use of group A or B plasma was within expectation, showing effective reduction of isoagglutinin titers for pre-operative desensitization and efficacy for treatment of post-operative patients. No immediate hemolytic transfusion reaction was reported. DISCUSSION While validation in a larger cohort of patients is necessary, our limited experience have shown satisfactory clinical outcomes without adverse events. CONCLUSIONS Use of incompatible group A or B plasma is a viable option when group AB plasma is limited.

Abstract
Hyperviscosity syndrome (HVS) is a life-threatening syndrome caused by high concentrations of large plasma proteins like IgM, rheumatoid factor, and other immune complexes, leading to increased blood viscosity and symptoms such as visual abnormalities, neurological impairment, bleeding diathesis, and thrombosis. While Waldenström's macroglobulinemia accounts for 80% to 90% of cases, HVS may develop in other clinical settings characterized by elevations in plasma proteins. Limited evidence currently exists describing the safety and efficacy of therapeutic plasma exchange (TPE) for the management of HVS secondary to non-neoplastic conditions. We report a case of recurrent HVS associated with juvenile rheumatoid arthritis and Felty syndrome that demonstrated improvement in clinical symptoms following initiation of TPE. These findings suggest that TPE may be utilized as an adjunct treatment option in patients with HVS secondary to autoimmune disorders.

Abstract
A 12 week‐old Nigerian dwarf (Capra aegagrus hircus) buck kid was hospitalized for management of obstructive urolithiasis. Postoperatively, he was inadvertently administered 16‐times greater than his calculated dose of a nonsteroidal anti‐inflammatory drug (NSAID; 17.5 mg/kg flunixin meglumine, IV). The goat was treated with intravenous administration of lipid emulsion (ILE) prior to membrane‐based therapeutic plasma exchange (mTPE) under general anesthesia. The increased coagulability inherent to small ruminants in comparison with dogs and cats warranted specific adjustments in the prescription of anticoagulation, blood flow, and filtration fraction to avoid circuit clotting during mTPE. Serum flunixin meglumine concentration measured before, during, and after mTPE revealed marked reduction in drug concentration. After the combined treatments, no clinical evidence of NSAID gastrointestinal or renal toxicosis was detected. This case report describes successful management of flunixin meglumine overdose in a small ruminant using combined ILE and mTPE.

Abstract
For ABO-incompatible liver transplantation (ABO-i LT), therapeutic plasma exchange (TPE) is performed preoperatively to reduce the isoagglutinin titer of anti-ABO blood type antibodies. We evaluated whether perioperative high isoagglutinin titer is associated with postoperative risk of acute kidney injury (AKI). In 130 cases of ABO-i LT, we collected immunoglobulin (Ig) G and Ig M isoagglutinin titers of baseline, pre-LT, and postoperative peak values. These values were compared between the patients with and without postoperative AKI. Multivariable logistic regression analysis was used to evaluate the association between perioperative isoagglutinin titers and postoperative AKI. Clinical and graft-related outcomes were compared between high and low baseline and postoperative peak isoagglutinin groups. The incidence of AKI was 42.3%. Preoperative baseline and postoperative peak isoagglutinin titers of both Ig M and Ig G were significantly higher in the patients with AKI than those without AKI. Multivariable logistic regression analysis showed that preoperative baseline and postoperative peak Ig M isoagglutinin titers were significantly associated with the risk of AKI (baseline: odds ratio 1.06, 95% confidence interval 1.02 to 1.09; postoperative peak: odds ratio 1.08, 95% confidence interval 1.04 to 1.13). Cubic spline function curves show a positive relationship between the baseline and postoperative peak isoagglutinin titers and the risk of AKI. Clinical outcomes other than AKI were not significantly different according to the baseline and postoperative peak isoagglutinin titers. Preoperative high initial and postoperative peak Ig M isoagglutinin titers were significantly associated with the development of AKI. As the causal relationship between high isoagglutinin titers and risk of AKI is unclear, the high baseline and postoperative isoagglutinin titers could be used simply as a warning sign for the risk of AKI after liver transplantation.

Abstract
The stiff person syndrome (SPS) is an extremely rare neurological disorder with primarily immune-mediated etiology. The cardinal symptoms are progressive, fluctuating axial/proximal limb muscle stiffness and spasms. The diagnosis is based on the clinical picture, electromyography examination and detection of antibodies to glutamic acid decarboxylase (anti-GAD). Adverse effects of medications might preclude its use or increase in dosing, therefore symptomatic and/or immunomodulatory medical therapy might be ineffective in acute exacerbation of the disease. We present a case of a 49-year-old female with exacerbation of SPS, in whom some standard pharmacotherapy could not be introduced (clonazepam, baclofen used in the past) and doses of existing standard medications could not be increased (diazepam, gabapentin, and levetiracetam) due to adverse effects. Moreover, a newly introduced medication (methylprednisolone) also led to a serious adverse effect (severe hyperglycemia). The patient underwent therapeutic plasma exchange (TPE) with good effect and no complications. We review the literature regarding the efficacy and safety profile of TPE in exacerbation of SPS unresponsive to medical therapy. The procedure seems to have a good safety profile as an adjunct therapy for exacerbation of SPS not responding to standard medical therapy in this patient population.

Abstract
Aims: The aim of this study was to evaluate the indications, adverse reactions, and outcome of therapeutic plasma exchange (TPE) in myasthenia gravis (MG) patients. Settings and Design: Retrospective Observational study. Methods and Material: A total of 18 patients of MG had undergone 18 cycles and 87 session of TPE at our Institution, a tertiary care center in Western India. It was performed using a single volume plasma exchange with intermittent cell separator (Freseniouscomtec), subclavian central line access, and with alternate day interval. Outcome was assessed shortly after each session and overall outcome at the time of discharge. Results: Total of 68 patients of MG were admitted to Neurology Intensive care unit (ICU) during the study period [January 2016–December 2019]. Out of them, TPE was done in 18 patients. Among the 18 patients, 11 patients had myasthenic crisis and 7 patients had worsening of MG. The mean number of TPE session was 4.2(SD ± 1.2), volume exchange was 2215 ml (SD ± 435); overall incidence of adverse reaction was 33.3%. All patients had immediate benefits of each TPE cycle. Good acceptance of procedure was observed in 72.2% of patients. Conclusions: TPE is cost-effective rapid therapy for myasthenic crisis and progressive myasthenia gravis. It reduces ICU stays and improves outcome.

Abstract
Novel immune-modulating anticancer drugs are being used with increasing frequency. With increased use, there are more frequent cases of toxicities caused by these drugs, termed immune-related adverse events (irAEs). We present a case in which we successfully treated a case of severe, steroid-refractory, nivolumab-induced myocarditis with therapeutic plasma exchange (TPE). Nivolumab is an immune checkpoint inhibitor (ICI) which blocks programmed death receptor-1 (PD-1). This blockade allows for enhanced T-cell function and increased anti-tumor response. The patient presented with signs and symptoms of heart failure and was found to have a significantly depressed cardiac ejection fraction. Over the course of her five TPE procedures, she improved clinically and was discharged home with improved left ventricular ejection function. This case suggests an emerging role of TPE in the management of severe ICI-induced toxicity, such as myocarditis.

Abstract
Guillain-Barré syndrome is an acute immune-mediated disease that affects the peripheral nervous system, with progressive motor deficit in the limbs, sometimes involvement of the cranial nerves and possible impairment of the autonomic nervous system. Due to the respiratory and autonomic nervous dysfunction, the disease has the potential to be fatal. Although modern methods of treatment have significantly improved patient prognosis, many patients nevertheless experience significant neurological sequelae. The practical applicability of plasmapheresis was illustrated in our case report. We report the case of a 27-year-old man who had a mild viral respiratory tract infection 1 week prior to the onset of disease with gradual development of a motor deficit, urinary retention, slight swallowing difficulties and mild respiratory dysfunction. Nerve conduction studies were performed and the diagnosis of acute motor axonal neuropathy phenotypic variant of Guillain-Barré syndrome was established. Autoimmune and inflammatory diseases, infectious diseases, endocrinopathies, neoplastic diseases, intoxications, metabolic diseases and vitamin deficiencies were ruled out. Our patient attended four sessions of therapeutic plasma exchange performed using peripheral venous approach with two needles with significant recovery of the motor deficit. The patient was discharged 1 week later on maintenance kinetotherapy with further favorable evolution. In conclusion, we report a good evolution as a result of therapeutic plasma exchange in a patient with acute motor axonal neuropathy phenotypic variant of Guillain-Barré syndrome. The procedure is well-tolerated and can be performed safely by peripheral approach not only in the intensive care unit but also in a neurology clinic.

Abstract
Antibody-Mediated Rejection (AMR) due to donor-specific antibodies (DSA) is associated with poor outcomes after lung transplantation. Currently, there are no guidelines regarding the selection of treatment protocols. We studied how DSA characteristics including titers, C1q, and mean fluorescence intensity (MFI) values in undiluted and diluted sera may predict a response to therapeutic plasma exchange (TPE) and inform patient prognosis after treatment. Among 357 patients consecutively transplanted without detectable pre-existing DSAs between 01/01/16 and 12/31/18, 10 patients were treated with a standardized protocol of five TPE sessions with IVIG. Based on DSA characteristics after treatment, all patients were divided into three groups as responders, partial responders, and nonresponders. Kaplan-Meier Survival analyses showed a statistically significant difference in patient survival between those groups (P = 0.0104). Statistical analyses showed that MFI in pre-TPE 1:16 diluted sera was predictive of a response to standardized protocol (R2 = 0.9182) and patient survival (P = 0.0098). Patients predicted to be nonresponders who underwent treatment with a more aggressive protocol of eight TPE sessions with IVIG and bortezomib showed improvements in treatment response (P = 0.0074) and patient survival (P = 0.0253). Dilutions may guide clinicians as to which patients would be expected to respond to a standards protocol or require more aggressive treatment.

Abstract
This paper focuses on the derivation and simulation of mathematical models describing new plasma fraction in blood for patients undergoing simultaneous extracorporeal membrane oxygenation and therapeutic plasma exchange. Models for plasma exchange with either veno-arterial or veno-venous extracorporeal membrane oxygenation are considered. Two classes of models are derived for each case, one in the form of an algebraic delay equation and another in the form of a system of delay differential equations. In special cases, our models reduce to single compartment ones for plasma exchange that have been validated with experimental data (Randerson et al., 1982, Artif. Organs, 6, 43-49). We also show that the algebraic differential equations are forward Euler discretizations of the delay differential equations, with timesteps equal to transit times through model compartments. Numerical simulations are performed to compare different model types, to investigate the impact of plasma device port switching on the efficiency of the exchange process, and to study the sensitivity of the models to their parameters.

Abstract
Clinically amyopathic dermatomyositis (CADM) is a rare, aggressive variant of dermatomyositis associated with interstitial lung disease (ILD) and refractoriness to immunosuppressants. Antibodies against melanoma differentiation-associated gene 5 (MDA-5) are often found in patients with CADM. We report a patient with advanced CADM with ILD and MDA-5 antibodies who failed to improve with immunosuppressants. We performed 2 TPE over 3 days, using 5% albumin as replacement fluid. Although five total TPE were planned, he was transferred for lung transplant evaluation after the second TPE; he died 16 days after transfer without receiving a transplant. A literature review identified four patients with CADM and MDA-5 antibodies treated with TPE; all experienced symptomatic improvement of their ILD. We attribute our patient's outcome to the advanced nature of his disease rather than a failure of TPE. Additional research may indicate a possible reclassification of CADM with MDA-5 antibodies in future ASFA guidelines.

Abstract
A 47-year-old male with stage IV pancreatic cancer developed gemcitabine-induced thrombotic microangiopathy (GiTMA) after treatment with gemcitabine and nab-paclitaxel. GiTMA is a rare and life-threatening complication with an incidence ranging from 0.015% to 1.4% and reported mortality rate ranging from 50% to 90%. Clinically, GiTMA manifests as microangiopathic hemolytic anemia, thrombocytopenia, and renal failure. Early identification of GiTMA is essential to initiate early treatment and improve survival. Treatment of GiTMA includes discontinuation of gemcitabine, along with initiation of steroids, therapeutic plasma exchange (TPE), rituximab, and eculizumab. To our knowledge, this is the first case of GiTMA treated with ravulizumab, a long-acting complement inhibitor. Given the increasing number of patients treated with gemcitabine and seriousness of this complication, it is important for physicians to be aware of this disease entity and maintain a high index of suspicion when evaluating patients with microangiopathic hemolytic anemia, thrombocytopenia, and renal failure.

Abstract
OBJECTIVE To examine the efficacy of therapeutic plasma exchange (TPE) in patients critically ill with Crimean-Congo hemorrhagic fever (CCHF). METHODS Patients with CCHF received supportive treatment (ST) or TPE. After laboratory and clinical evaluations, the patients were divided into mild, moderate, and severe CCHF groups according to the severity score index (SSI). To assess the efficacy of TPE, the incubation period, time of admission to hospital, hospitalization duration, mortality rate and times to recovery of the platelet count and aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were compared between patients receiving ST and TPE. RESULT A total of 119 confirmed CCHF cases was analyzed. The median SSIs were 7 in the TPE group and 5 in the ST group. The SSI stages, median incubation times and admission times were similar in the two groups. However, the duration of hospitalization was longer in the TPE group. The overall mortality rates were 9% (3 of 33 patients) in the TPE group and 16% (5 of 31 patients) in the ST group; the difference was significant. The platelet count recovered after a median of 6 (4-7) days in the ST group. CONCLUSION The mortality rate was lower in the TPE group than in the ST group, but the duration of hospitalization and the time to platelet recovery were longer in the TPE group than in the ST group. TPE did not contribute significantly to the prognosis of patients with intermediate-severity CCHF. However, TPE might be efficacious in patients with severe CCHF.

Abstract
BACKGROUND AND AIMS Therapeutic plasma exchange (TPE) is increasingly used throughout the medical field. We aimed to analyze the various aspects of TPE practices at our hospital in terms of clinical indications, technical feasibility, safety, outcome as well as complications associated with the procedures. MATERIALS AND METHODS The data included demographic profiles, clinical parameters, and technical characteristics of each TPE procedure. All the information was noted in data spread sheet (Microsoft Excel 2013) for further analysis. RESULTS This is a 3-year retrospective study of total 266 TPE procedures carried out on 92 patients with different clinical conditions. Out of them, 55 (59.8%) were male and 37 (40.2%) were female patients. There were six major categories such as (1) neurological, (2) hematological, (3) gastrological, (4) renal, (5) rheumatic, and (6) others. The TPE treatment was highest in neurology group (60.2%), followed by gastrology group (24.4%). Most of the procedures (82.6%) were according to the American society of apheresis 2016 I or II categories (76/92 patients). CONCLUSION TPE is beneficial and used as primary or secondary adjunctive therapy for a wide spectrum of various diseases and syndromes. TPE is considered as safe, cost-effective, and life-saving treatment modality in various diseases.

Abstract
Thyroid storm is a rare but life-threatening endocrinological emergency with significant mortality ranging from 10-30% with multi-organ involvement and failure. In view of the rarity of this condition and efficacy of established first line medical treatment, use of extra-corporeal treatments are uncommon, not well-studied, and its available evidence exists only from case reports and case series. We describe a 28-year-old man who presented with an out-of-hospital cardiac arrest secondary to thyroid storm. Despite conventional first-line pharmacotherapy, he developed cardiogenic shock and circulatory collapse with intravenous esmolol infusion, as well as multi-organ failure. He required therapeutic plasma exchange, concurrent renal replacement therapy, and veno-arterial extra-corporeal membrane oxygenation, one of the few reported cases in the literature. While there was clinical stabilization and improvement in tri-iodothyronine levels on three extra-corporeal systems, he suffered irreversible hypoxic-ischemic brain injury. We reviewed the use of early therapeutic plasma exchange and extra-corporeal membrane oxygenation, as well as the development of other novel extra-corporeal modalities when conventional pharmacotherapy is unsuccessful or contraindicated. This case also highlights the complexities in the management of thyroid storm, calling for caution with beta-blockade use in thyrocardiac disease, with close monitoring and prompt organ support.

Abstract
The mortality rate of sepsis-associated disseminated intravascular coagulation (DIC) is high. This study aimed to explore the efficacy of therapeutic plasma exchange (TPE) in sepsis-associated DIC patients by improving endothelial function. A total of 112 sepsis-associated DIC patients were randomly divided into the TPE group (n = 40), the heparin (HP) group (n = 36), and the SHAM group (n = 36). The SHAM group received conventional treatment; the HP group was treated with HP based on conventional treatment; and the TPE group received conventional treatment plus TPE. The differences in thromboelastogram (TEG), platelet (PLT), coagulation function, and the endothelial cell (EC) injury biomarkers at 6 h, 24 h, 48 h, 72 h, and 7 days after TPE were compared among the three groups, and the three groups were compared in terms of Acute Physiology and Chronic Health Evaluation II (APACHE II) score, Sepsis-Related Organ Failure Assessment (SOFA) score, the length of intensive care unit (ICU) hospitalization, 28-day mortality rate, 28-day cumulative survival rate, the incidence of bleeding events, the incidence of acute kidney injury (AKI), and acute respiratory distress syndrome (ARDS). The efficacy of TPE is superior to the HP in increasing PLT, improving coagulation function, increasing the 28-day cumulative survival rate, and reducing the length of ICU hospitalization, 28-day mortality, and the incidence of bleeding events, AKI, and ARDS with statistically significant differences (P < .05). Moreover, the effect of TPE outperforms HP on the EC injury biomarkers with statistically significant differences (P < .05). Our results suggest that TPE may be more effective than HP in the treatment of patients with sepsis-associated DIC. The possible mechanism is via improving endothelial function.

Abstract
Therapeutic plasma exchange in children is increasingly recognized as a life-saving treatment and is challenged by some technical considerations. As extracorporeal membrane oxygenation has been used for nearly half a century for refractory reversible respiratory and/or cardiac failure in both pediatric and adult populations, it may serve as an extracorporeal platform for therapeutic plasma exchange. It is most commonly described in patients with sepsis with multiple organ failure or thrombocytopenia associated multi organ failure. Additional pathophysiological processes of inflammatory and immunological storms might benefit from the combination of extracorporeal membrane oxygenation and plasma exchange. This is a nonmethodological review of English-language reports of therapeutic plasma exchange performed in patients supported by extracorporeal membrane oxygenation, both pediatric and adult, searching six databases, MEDLINE, Clinical Key, GOOGLE SCHOLAR, CINAHL, Cochrane library, and EMBASE.

Abstract
We report a case of Wegener's granulomatosis (WG) who very well responded to the combination strategy of therapeutic plasma exchange (TPE) and immunosuppression. The patient was a 38-year-old female, diagnosed with severe form of WG. A total of seven cycles was performed with 1.3 total plasma volumes (TPVs) on every alternate day. Standard induction therapy was also started that comprised of a combination of 500 mg intravenous (i.v.) cyclophosphamide and methylprednisolone 1 g slow i.v. daily for 3 days followed by oral prednisolone 60 mg daily for 4 weeks. After seven cycles of TPE, the patient improved and hence TPE was stopped.

Abstract
BACKGROUND AND AIMS Although desensitization is well established, concerns about graft outcome, patient survival and rejection still exist. The present study aims at comparing outcomes of renal transplant recipients across simultaneous ABO and human leukocyte antigen (HLA) incompatibility barriers to those with ABO or HLA incompatibility alone. MATERIALS AND METHODS This was a retrospective study conducted from October 2015 to December 2018. All patients with a clinical diagnosis of chronic kidney disease, who were prospective HLA incompatible (HLAi) and/or ABO incompatible (ABOi) renal transplant recipients were included. A total of 400 cases including 36 ABOi transplants, 154 HLAi transplants, 10 simultaneously ABO and HLA incompatible transplants, and 200 ABO (ABOc) and HLA (HLAc) compatible kidney transplants from living donors were included. RESULTS There were significantly more number of blood transfusions, previous transplants and pregnancies in HLAi transplant recipients relative to the ABOi or the control group. Mean number of therapeutic plasma exchange procedures per patient and mean plasma volume processed per procedure were slightly higher in the ABOi + HLAi category. The incidence of graft dysfunction due to suspected antibody-mediated rejection during first year was highest in the ABOi + HLAi group, followed by ABOc + HLAi and ABOi + HLAc, lowest in the ABOc + HLAc category. Mean time to first episode of graft dysfunction was significantly shorter with incompatible transplants. There were no kidney transplant recipient deaths in the study. CONCLUSION Patient outcome and graft outcomes observed with incompatible transplants were not worse than those observed with compatible transplants.
