RESUMO

INTRODUCTION: Thrombotic thrombocytopenic purpura (TTP) is a rare but potentially fatal hematological disorder that requires urgent treatment. Once the diagnosis has been made, plasma exchange (PE) must be started immediately and until a response is obtained. AIM: Evaluate PE in terms of responses and complications in the treatment of TTP. METHODS: This was a monocentric, descriptive, retrospective study including patients in whom TTP was diagnosed and treated with plasmapheresis in the clinical hematology department at Aziza Othmana Hospital, between January 2010 and December 2020. RESULTS: Our study included 26 patients. PE was initiated within a median of 1 day. The rhythm of exchanges was daily in 22 patients. Twenty PE-related complications were noted, hypocalcemia being the most frequent (30%). CR was achieved in 15 patients after PE alone. Nine patients were refractory, and six received 2nd-line treatment, with CR achieved in five patients. Relapse was noted in six patients (40%). They were treated by PE and only one patient received rituximab. Four patients had a response. The overall response rate was 69% and overall mortality was 30%. OS at 2 years was 68,3% and RFS was 84,4%. Factors associated with the achievement of CR were the fall in LDH at D5 of treatment (p=0,027,OR=0,59 ;IC 95%[0,32-1,08]) and the daily rhythm of PE (p=0,005, OR=0,35; IC 95%[0,14-0,91]). CONCLUSION: Our results were comparable to those of the literature, but the rate of refractory disease was higher. Rituximab may enhance our results.

RESUMO

Bullous pemphigoid is the most common autoimmune blistering disease induced by autoantibodies against basement membrane anchoring proteins (anti-BP-180 and anti-BP-230). The disease generally appears after the age of 70 and is associated with a 23.5% 1-year mortality, especially in diabetics, or in the presence of ischemic heart disease and high anti-BP-180. Treatment starts with topical steroids but some patients may require oral steroids and systemic immunosuppression. We, hereby, discuss a diabetic patient on chronic hemodialysis, with severely relapsed bullous pemphigoid under biotherapy with omalizumab, who was successfully treated with five sessions of double filtration plasmapheresis, thus avoiding the need for systemic steroids.

RESUMO

ABSTRACT: This is a case description of a patient with bipolar disorder undergoing lithium therapy who received plasmapheresis for neuromyelitis optica spectrum disorder. Plasmapheresis resulted in lower and subtherapeutic serum lithium levels. Using therapeutic drug monitoring, a dose escalation of 80% was necessary to maintain therapeutic serum lithium levels. This underscores the importance of individualized therapy through therapeutic drug monitoring.

RESUMO

BACKGROUND: Intravenous immunoglobulin (IVIg) and plasmapheresis (PLEX) are recommended in moderate to severe Guillain-Barré Syndrome (GBS), but there is paucity of studies evaluating its effect on nerve conduction studies (NCS). We report the effect of IVIg and PLEX on the NCS parameters and clinical outcomes compared to natural course (NC) of GBS patients. METHOD: Moderate to severe GBS patients were included based on clinical, cerebrospinal fluid, and NCS finding. Six motor and sensory nerves were evaluated at admission, one month and 3 months, and NCS subtyping was done. Axonal and demyelination burden in motor nerves and early reversible conduction block (ERCB) were noted. Patients receiving IVIg, PLEX or on NC were noted. Outcome was defined at 3 months into complete, partial and poor using a 0-6 GBS Disability Scale (GBSDS). RESULT: Seventy-two patients were included, whose median age was 36 years and 22(30.6 %) were females. 44 patients received IVIg, 9 PLEX and 19 were in NC, and they had comparable peak disability. AIDP was the dominant subtype at admission (58.3 %), which remained so at 3 months (50 %). The shift of subtypes was the highest from the equivocal group followed by AMAN and the least from AIDP. IVIg and PLEX group had more reduction in axonal burden and had ERCB compared to NC. 33(44 %) patients had complete recovery, and 40(55.5 %) patients had concordance in clinical and neurophysiological outcome. CONCLUSION: Transition of GBS subtype may occur at follow-up from all the subtypes, the highest from the equivocal and the lowest from the AIDP group. IVIg/PLEX treatment may help in reducing conduction block and axonal burden.

RESUMO

OBJECTIVES: Preeclampsia (PE) is a major cause of maternal and fetal mortality, and preterm birth. Previous studies indicate that lipid-apheresis may prolong pregnancy, namely heparin-mediated extracorporeal LDL-precipitation (HELP)- and dextran sulfate cellulose (DSC)-apheresis. We now report on double membrane plasmapheresis (DFPP) in early-onset preeclampsia (eoPE). STUDY DESIGN: Open pilot study assessing the prolongation of pregnancy in PE by lipoprotein-apheresis (DRKS00004527). Two women with eoPE were treated by DFPP and compared to a historical cohort of 6 patients with eoPE treated by HELP-apheresis (NCT01967355). MAIN OUTCOME MEASURES: Clinical outcome of mothers and babies and prolongation of pregnancies (time of admission to birth). RESULTS: Patient 1 (33y; 22 + 5/7GW) received 4 DFPP. Delivery day 19; birthweight 270 g; weight at discharge 2134 g on day 132. Patient 2 (35y; 21 + 4/7GW) received 2 DFPP. Delivery day 19; birthweight 465 g; weight at discharge 2540 g on day 104. DFPP was well tolerated by both patients. CONCLUSIONS: DFPP proved to be save and pregnancies remained stable as long as 19 days. Although babies were born very preterm both babies could finally be dismissed from hospital. No relevant clinical differences between DFPP and HELP-apheresis could be observed. Therefore, DFPP may extend the range of available apheresis techniques to prolong pregnancies in early-onset preeclampsia. However, further studies are necessary to gain more information.

RESUMO

RATIONALE: Thrombotic thrombocytopenic purpura (TTP) is a rare thrombotic microangiopathy caused by reduced activity of the von Willebrand factor-cleaving protease (ADAMTS13), which can be life-threatening. The patient reported in this case study also had concurrent Sjögren syndrome and renal impairment, presenting multiple symptoms and posing a great challenge in treatment. PATIENT CONCERNS: A 25-year-old woman in the postpartum period visited the hospital due to indifference in consciousness for more than 1 day following cesarean section 8 days prior. DIAGNOSIS: Notable decreases were observed in platelets, hemoglobin, creatinine, and ADAMTS13 levels. After a consultative examination by an ophthalmologist, she was diagnosed with retinal hemorrhage in the right eye and dry eye syndrome in both eyes. INTERVENTIONS: Having been diagnosed with TTP with Sjögren syndrome and renal impairment, she received repeated treatments with plasmapheresis combined with rituximab. OUTCOMES: Following treatment and during the follow-up period, the patient's platelet counts and bleeding symptoms significantly improved. LESSONS: TTP has a high mortality rate, and when combined with Sjögren syndrome and renal impairment, it poses an even greater challenge in treatment. However, after administering standard plasmapheresis combined with rituximab treatment, the treatment outcome is favorable.

RESUMO

As no unified treatment protocol or evidence yet exists for plasmapheresis without plasma, this study explored the outcomes of using 4% human albumin (ALB) solution as a replacement solution in patients undergoing plasma exchange for multiple myeloma (MM) patients with acute kidney injury (AKI). This study was prospectively registered (ChiCTR2000030640 and NCT05251896). Bortezomib-based chemotherapy plus therapeutic plasmapheresis (TPP) with 4% human ALB solution was assessed for three years in patients with MM aged >18 years, with AKI according to the Kidney Disease Improving Global Outcomes criteria, and without previous renal impairment from other causes. The primary endpoints were changes in renal function over 18 weeks and survival outcomes at 36 months. The secondary endpoints were the incidence of adverse reactions and symptom improvement. Among the 119 patients included in the analysis, 108 experienced renal reactions. The M protein (absolute changes: median -12.12%, interquartile ranges (IQRs) -18.62 to -5.626) and creatine (median -46.91 µmol/L, IQR -64.70 to -29.12) levels decreased, whereas the estimated glomerular filtration rate (eGFR) increased (median 20.66 mL/(min·1.73 m2), IQR 16.03-25.29). Regarding patient survival, 68.1% and 35.3% of patients survived for >12 and >36 months, respectively. The three symptoms with the greatest relief were urine foam, poor appetite, and blurred vision. All 11 patients (7.6%) who experienced mild adverse reactions achieved remission. In conclusion, in MM patients with AKI, plasma-free plasmapheresis with 4% human ALB solution and bortezomib-based chemotherapy effectively alleviated light chain damage to kidney function while improving patient quality of life.

RESUMO

Since 2019 when a cluster of cases with acute respiratory distress syndrome (ARDS) associated with e-cigarettes in the United States was reported, there have been increasing numbers of reports. Electronic-cigarette or Vaping Use-associated Lung Injury (EVALI) represents a recent entity of respiratory clinical syndromes, primarily in young adults. We report a previously healthy 16-year-old boy who developed severe ARDS following a brief nonspecific prodromal phase after excessive consumption of e-cigarettes. Despite maximum intensive care therapy, including several weeks of venovenous extracorporeal membrane oxygenation, plasmapheresis and repeated administration of immunoglobulins seemed the only way to achieve therapeutic success. Although many case reports have been published, to our knowledge, there are none to date on the therapeutic use of plasmaphoresis in severe EVALI. This case highlights the clinical features of EVALI and the diagnostic dilemma that can arise with EVALI occurring against the background of an expired SARS-CoV-2 infection, with a paediatric inflammatory syndrome (PIMS) as differential diagnosis. EVALI is a diagnosis of exclusion, and the medical history of vaping and e-cigarette use can provide valuable clues. Ethical approval for this case report (protocol number 23-145 RS) was provided by the Ethical Committee of the Department of Medicine, Philipps-Universität Marburg, Germany on 13 th of June 2023. Written informed consent to publish this case and the associated images was obtained from the patient and his mother.

RESUMO

OBJECTIVES: Paediatric acute liver failure (PALF) is a life-threatening disease. Management aims to support hepatic regeneration or to bridge to liver transplantation. High-volume plasmapheresis (HVP) removes protein-bound substances, alleviates inflammation, and improves survival in adult acute liver failure. However, experience with HVP in PALF is limited. Aim of this study is to report on feasibility, safety, efficacy and outcomes of HVP in PALF. METHODS: Retrospective observational study in children with PALF. HVP was performed upon identification of negative prognostic indicators, in toxic aetiology or multiorgan failure (MOF). Exchanged volume with fresh-frozen plasma corresponded to 1.5-2.0 times the patient's estimated plasma volume. One daily cycle was performed until the patient met criteria for discontinuation, that is, liver regeneration, liver transplantation, or death. RESULTS: Twenty-two children with PALF (body weight 2.5-106 kg) received 1-7 HVP cycles. No bleeding or procedure-related mortality occurred. Alkalosis, hypothermia and reduction in platelets were observed. Haemolysis led to HVP termination in one infant. Seven children (32%) survived with their native livers, 13 patients (59%) underwent liver transplantation. Two infants died due to MOF. Overall survival was 86%. International normalization ratio (INR), alanine aminotransaminases (ALT), bilirubin and inotropic support were reduced significantly (p < 0.05) after the first HVP-cycle (median): INR 2.85 versus 1.5; ALT 1280 versus 434 U/L; bilirubin 12.7 versus 6.7 mg/dL; norepinephrine dosage 0.083 versus 0.009 µg/kg/min. Median soluble-interleukin-2-receptor dropped significantly following HVP (n = 7): 2407 versus 950 U/mL (p < 0.02). CONCLUSIONS: HVP in PALF is feasible, safe, improves markers of liver failure and inflammation and is associated with lowering inotropic support. Prospective and controlled studies are required to confirm efficacy of HVP in PALF.

RESUMO

BACKGROUND: The demand for plasma products is growing, necessitating an increase in plasma collection by plasmapheresis. While the 20th edition of the European Guidelines permits plasma donors in Europe to donate with 96-h donation intervals, the potential short- and long-term consequences of high-frequency plasma donations on donor health remain unknown. This study aims to measure the effect of plasma donation frequency on plasma protein composition, including total serum protein (TSP) and immunoglobulin G (IgG), in Norwegian male blood donors. METHODS: This randomized controlled trial (RCT) included 120 male blood donors who were randomized into two intervention groups and one control group: high-frequency plasma donors (HFPDs) who donated 650 mL of plasma 3 times every 2 weeks, whereas regular-frequency plasma donors (RFPDs) who donated 650 mL of plasma 1 time every 2 weeks. The control group consisted of whole blood donors. The primary outcomes are the concentrations of TSP and IgG. DISCUSSION: The findings from this study may have implications for recommendations related to donor health and plasma donation frequencies and may contribute to supporting the strategic independence of plasma products in Norway and Europe without compromising donor health. TRIAL REGISTRATION: ClinicalTrials.gov: NCT05179200 . Registered December 20th, 2021.

RESUMO

Therapeutic apheresis is an important hematological and nephrological method for conditions with altered plasma composition. It is also indicated for the removal of protein-bound molecules, such as bilirubin. Several techniques can remove these compounds, such as the extracorporeal circulation molecular adsorption system (MARS), plasma exchange (PEX), and plasma adsorption and perfusion (PAP). Here we report our experience in the comparison between MARS, PEX and PAP, since current guidelines do not specify which method is the most appropriate and under which circumstances it should be used. The choice of technique cannot be based on the desired plasma bilirubin concentration, since these three techniques show similar results with a similar final outcome (exitus). In fact, PAP, PEX and MARS significantly reduce bilirubin levels, but the degree of reduction is not different among the three. Furthermore, the three techniques do not differ in the rate of cholinesterase change, while less reduction of liver transaminases was found by using PAP. MARS should be preferred in the case of renal involvement (hepatorenal syndrome with hyperbilirubinemia). PAP has the advantage of being simple and inexpensive. PEX remains an option when emergency PAP is not available, but the risk of using blood products (plasma and albumin) must be considered.

RESUMO

PURPOSE: To compare the efficacy of treatment of optic neuritis (ON) with corticosteroids (CTC) alone, CTC+plasmapheresis (PLP), and CTC+intravenous immunoglobulin (IVIG). DESIGN: After an episode of ON, although visual recovery is usually good, some patients may have significant visual sequelae. While the efficacy of first-line CTC is now indisputable, there is no consensus on the nature of second-line treatment. To date, no systematic review has compared the efficacy of treatment of ON with CTC alone, CTC+plasmapheresis (PLP), and CTC+intravenous immunoglobulin (IVIG). A meta-analysis is needed to compare the efficacy of PLP and IVIG in steroid-resistant ON. METHODS: This systematic review included all studies comparing at least two of the three treatments for steroid-resistant ON (CTC alone, CTC+PLP, and CTC+IVIG). From all articles published on PubMed between January 2000 and June 2022, two independent ophthalmologists selected studies of interest using the PRISMA method. Methodology, patient characteristics, and outcomes were identified. A network metaanalysis was then performed to compare the efficacy of the three treatments. RESULTS: Six comparative studies were included, representing 209 patients. The percentage of significant visual recovery after CTC alone, CTC+PLP, and CTC+IVIG in the acute treatment of steroid-resistant ON was 30 %, 45 %, and 77 %, respectively. Comparison of CTC+IVIG vs CTC alone, CTC+PLP vs CTC only, and CTC+PLP vs CTC+IVIG yielded odds ratios of 12.81, 2.47, and 0.19 respectively. CONCLUSION: Treatment of steroid-resistant ON with CTC+PLP or CTC+IVIG is more effective than treatment with CTC alone. Although no study has directly compared the two treatments, IVIG may be more effective than PLP.

RESUMO

BACKGROUND: Myasthenia gravis (MG) is an autoimmune neuromuscular disorder characterized by muscle weakness, posing significant challenges to patients' daily lives. Intravenous immunoglobulin (IVIG) and plasmapheresis are two prominent immunomodulatory therapies used in MG management, but the choice between them remains a clinical dilemma. This systematic review and meta-analysis aim to evaluate the comparative efficacy of IVIG versus plasmapheresis in MG management. METHODS: We adhered to PRISMA guidelines and prospectively registered the review protocol in PROSPERO. Systematic search across electronic databases identified 14 studies meeting inclusion criteria. Data from these studies were extracted, and assessed risk of bias. Primary outcomes included clinical efficacy, while secondary outcomes encompassed hospitalization, ventilation, antibody titers, and treatment-related complications. Statistical analysis was conducted using R software. RESULTS: The pooled results indicated that patients receiving plasmapheresis had higher odds of any improvement in MG symptoms compared to IVIG. However, change in severity scores did not significantly differ between the two treatments. Hospitalization durations were similar, but IVIG-treated patients tended to have shorter stays. Antibody titers, particularly anti-MUSK antibodies, favored plasmapheresis treatment. Complication rates were comparable between two groups. However, severe complications were more common in plasmapheresis. CONCLUSION: This comprehensive analysis suggests that plasmapheresis may offer superior short-term symptom improvement in MG compared to IVIG, while IVIG may lead to shorter hospital stays and lower complication rates. The choice between these treatments should be tailored to individual patient needs and disease characteristics. Further research is needed to explore long-term outcomes and mortality rates in MG management.

RESUMO

INTRODUCTION: Recently, the incidence of hypertriglyceridemia-associated pancreatitis (HTG-AP) has been increasing. The pathogenesis of lipogenic pancreatitis is not fully understood. This study aimed to retrospectively analyze the laboratory data, clinical manifestations, and prognosis of patients with lipid-derived pancreatitis who received lipid purification, to explore whether lipid purification is a better treatment for acute hyperlipidemic pancreatitis. METHODS: In this study, we enrolled five subjects diagnosed with HTG-AP at the Second Xiangya Hospital of Central South University between 2021 and 2022. We collected demographic data, medical histories, clinical manifestations, and laboratory data. All patients received routine therapy. Blood lipid purification was conducted using the double filtration plasmapheresis (DFPP) method. Plasma was separated from blood cells and purified to remove cholesterol, triglycerides, and low-density lipoprotein (LDL). SPSS was used for statistical analyses. RESULTS: Following a single lipoprotein apheresis (LA) treatment, significant improvements in serum lipid levels were observed. Three patients achieved triglyceride levels below 5.65 mmol/L within 24 h, while the remaining 2 patients experienced reductions of 82% and 78%, respectively. The average triglyceride level decreased from 36.82 to 7.27 mmol/L, representing an 80% reduction from baseline. Total cholesterol decreased by 59% on average, and LDL levels decreased by 69%. Statistically significant differences were observed in triglyceride and cholesterol levels before and after treatment. Four patients exhibited increased HDL levels posttreatment, while 1 patient showed a decrease. The average HDL/TC level was 21% higher after treatment. CONCLUSION: LA in HTG-AP effectively improves clinical symptoms, rapidly lowers lipid levels, and achieves good therapeutic outcomes.

RESUMO

Therapeutic plasma exchange (TPE) or plasmapheresis has been used in various life-threatening diseases as a primary treatment or in combination with other therapies. It was first successfully employed in the 1960s for diseases like Waldenström's disease and myeloma. Since then, TPE techniques using apheresis membranes have been introduced. Apheresis therapies separate plasma components from blood using membrane screening or centrifugation methods. TPE aims to remove substances involved in the pathophysiology of diseases. It selectively removes high-molecular-weight molecules, substances with prolonged half-life, and those associated with disease pathogenesis. TPE can be performed using membranes or centrifugation, with replacement of extracted plasma volume using albumin or fresh frozen plasma. TPE requires specific competencies in nephrology and can be prescribed and monitored by nephrologists and performed by dialysis nursing staff. TPE can be combined with adsorption-based therapies to enhance its effect, and this approach is called plasma filtration adsorption. Another variation is double plasma filtration, which selectively removes substances based on molecular size. TPE can also be combined with lipoprotein removal strategies for managing familial hypercholesterolemia. TPE is an affordable extracorporeal therapy that benefits patients with life-threatening diseases. It requires collaboration between nephrologists and other specialists, and our results demonstrate successful TPE without anticoagulation in general hospitalization or outpatient settings.

RESUMO

Therapeutic plasma exchange (TPE) is a treatment paradigm used to remove harmful molecules from the body. In short, it is a technique that employs a process that functions partially outside the body and involves the replacement of the patient's plasma. It has been used in the ICU for a number of different disease states, for some as a first-line treatment modality and for others as a type of salvage therapy. This paper provides a brief review of the principles, current applications, and potential future directions of TPE in critical care settings.

RESUMO

INTRODUCTION: Peripheral venous access (PVA) is recommended as a first-line vascular approach for therapeutic plasmapheresis with centrifugation methods but not filtration, which usually requires high blood flow. We evaluated the feasibility, efficacy, and safety of double-filtration plasmapheresis (DFPP) with PVA, using ultrasound guidance and regional citrate anticoagulation (RCA), i.e., PVA-RCA-DFPP in patients undergoing chronic DFPP. Secondly, we assessed the number of central venous catheters (CVCs) avoided. METHODS: A single-center retrospective study evaluated 22 adult patients on chronic DFPP to perform PVA-RCA-DFPP. They were classified into 3 groups: successful (i.e., completion of sessions with PVA), primary failure (i.e., no sessions completed), secondary failure (i.e., ≥1 session with PVA completed but secondary return with CVC or arteriovenous fistula). RESULTS: Among the 22 patients included (64% men), 7 patients (32%) were classified as primary failures (2 patient refusals, 5 inadequate PVAs), 1 patient (5%) as a secondary failure (due to uncomfortable venipunctures), and 14 patients (64%) as successful. In the successful group including 12 patients treated for chronic inflammatory demyelinating polyneuropathy (CIDP) and 2 patients for familial hypercholesterolemia (FH) (2 patients), 116 sessions were performed, with a median treated plasma volume of 4.3 L [IQR 3.6-4.6] (45 mL/kg) for a median duration of 134 min [IQR 122-144], and a median blood flow of 94 mL/min [IQR 87-103]. For the CIDP group, 90% of sessions achieved a plasma volume >1 TPV, and for the FH group 91% of sessions achieved an LDLc reduction >60%. Eleven sessions out of 116 (9%) were interrupted, mostly due to PVA dysfunction (5/11) and circuit clotting (4/11). Session interruptions decreased significantly between each patient's first and following sessions (29% to 7%, p = 0.009). CONCLUSION: Chronic PVA-RCA-DFPP can be performed safely and efficiently, avoiding the use of CVCs.

RESUMO

BACKGROUND: A common required duty of pathology resident physicians while rotating on transfusion medicine is the medical oversight of the therapeutic apheresis service. A task often performed on this clinical medicine service is formulating and writing orders for therapeutic apheresis procedures. The EpicCare tool called the therapy plan provides unique advantages over a standard electronic order set for therapeutic apheresis. MATERIALS AND METHODS: Transfusion medicine physicians, apheresis nurses, pharmacists, and information technology professionals collaborated to create therapy plans for three therapeutic apheresis procedures: plasmapheresis, red cell exchange, and photopheresis. RESULTS: Therapy plans were implemented and have been well-received for several years. Over a six-year time period, a total of 613 therapy plans were created and signed. We speculate that this implementation may have increased both physician efficiency and patient safety. CONCLUSION: This article reports our experience using therapy plans in EpicCare in order to raise awareness of this tool and to serve as an encouragement for wider adoption.
