J Neuroimmune Pharmacol 2021; 16:806-817. [PMID: 34599742 PMCID: PMC8714620 DOI: 10.1007/s11481-021-10004-9] [Citation(s) in RCA: 17] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2021] [Accepted: 07/22/2021] [Indexed: 11/30/2022]
Abstract
Autoimmune neurological disorders are commonly treated with immunosuppressive therapy. In patients with refractory conditions, standard immunosuppression is often insufficient for complete recovery or to prevent relapses. These patients rely on other treatments to manage their disease. While treatment of refractory cases differs between diseases, intravenous immunoglobulin, plasma exchange (PLEX), and immune-modulating treatments are commonly used. In this review, we focus on five autoimmune neurological disorders that were the themes of the 2018 Midlands Neurological Society meeting on PLEX in refractory neurology: Autoimmune Encephalitis (AE), Multiple Sclerosis (MS), Neuromyelitis Optica Spectrum disorders (NMOSD), Chronic Inflammatory Demyelinating Polyradiculoneuropathy (CIDP) and Myasthenia Gravis (MG). The diagnosis of inflammatory neuropathies is often challenging, and while PLEX can be very effective in refractory autoimmune diseases, its ineffectiveness can be confounded by misdiagnosis. One example is POEMS syndrome (characterized by Polyneuropathy Organomegaly, Endocrinopathy, Myeloma protein, Skin changes), which is often wrongly diagnosed as CIDP; and while CIDP responds well to PLEX, POEMS does not. Accurate diagnosis is therefore essential. Success rates can also differ within 'one' disease: e.g. response rates to PLEX are considerably higher in refractory relapsing remitting MS compared to primary or secondary progressive MS. When sufficient efforts are made to correctly pinpoint the diagnosis along with the type and subtype of refractory autoimmune disease, PLEX and other immunotherapies can play a valuable role in the patient management.

Abstract
The novel SARS-CoV-2 human coronavirus in Wuhan, China, has triggered a worldwide respiratory disease outbreak (COVID-19). Acute respiratory distress syndrome, multiorgan dysfunction and thrombotic events are among the leading causes of death in critically ill patients with COVID-19. The elevated inflammatory cytokines suggest that a "cytokine storm", also known as cytokine release syndrome, may play a major role in the pathology of COVID-19. In addition to anti-viral therapy and supportive treatment in critically ill patients, unique medications for this condition are also under investigation. Here we reviewed therapeutic options, including the antibody therapy that might be an immediate strategy for SARS-CoV-2 therapy.

The novel SARS-CoV-2 human coronavirus in Wuhan, China, has triggered a worldwide respiratory disease outbreak (COVID-19). Acute respiratory distress syndrome (ARDS), multiorgan dysfunction and thrombotic events are among the leading causes of death in critically ill patients with COVID-19. The elevated inflammatory cytokines suggest that a "cytokine storm", also known as cytokine release syndrome (CRS), may play a major role in the pathology of COVID-19. In addition to anti-viral therapy and supportive treatment in critically ill patients, unique medications for this condition are also under investigation.

Abstract
BACKGROUND Guillain-Barré syndrome (GBS) is an autoimmune disease that affects the peripheral nervous system. Severe motor deficit (SMD), respiratory impairment, cranial nerve involvement and autonomic dysfunction are associated with a poor prognosis. OBJECTIVE To investigate the association between the clinical-epidemiological characteristics and the discharge results among Peruvian patients with GBS. METHODS We carried out a retrospective observational study on patients with GBS who survived until discharge. We used the Brighton Collaboration's criteria and considered Hughes Severity Scale (HSS) scores greater than two to be SMD. We defined the discharge results as an improvement if the HSS score decreased by at least one point from admission to hospital discharge and defined hospital stay as prolonged if > 14 days. RESULTS We analyzed 92 patients, among whom 70.7% were male. Quadriparesis (81.1%) and hyporeflexia (86.8%) were the most characteristic manifestations. We observed that more than half of the cases were in summer and winter. Gastrointestinal infections were associated with a higher proportion of prolonged stays. The proportion of improvement was lower among patients who had an SMD at hospital admission. We confirmed these results through fitting in multivariate models. CONCLUSIONS The prolonged stay was related to previous gastrointestinal infection, while a less improvement in SMD individuals at admission. Prospective multicenter surveillance systems are needed for monitoring GBS cases in low-income settings like Peru.

Abstract
Objective Severe hypertriglyceridemia (SHTG; plasma triglycerides >1000 mg/dL) is a rare but serious complication in children who develop diabetic ketoacidosis (DKA) from uncontrolled or new-onset type 1 diabetes. Methods We present the case of a severely malnourished 16-year-old with a 10-month history of presumed type 2 diabetes managed with lifestyle modifications and metformin, who presented with SHTG, acute pancreatitis, and DKA. On examination, there was no evidence of lipemia retinalis, cutaneous xanthomas, or xanthelasma. He was initially treated with an insulin infusion and intravenous fluids. Despite this treatment, his pancreatitis symptoms worseneed and lipase level increased, necessitating 2 courses of plasmapheresis that immediately resolved his symptoms and dramatically improved his clinical status. He was discharged on hospital day 5. During his hospital admission, islet cell antigen 512, insulin, glutamic acid decarboxylase 65, and zinc transporter 8 autoantibodies were positive in the presence of insulinopenia, consistent with type 1 diabetes. Results Hypertriglyceridemia and hypercholesterolemia did not recur during follow-up, suggesting that the underlying mechanism for SHTG was insulin deficiency. Conclusion This report of SHTG, DKA, and pancreatitis in an adolescent highlights the safe, early initiation of plasmapheresis as an effective treatment. To our knowledge, plasmapheresis has rarely been used so early in the course of treatment for an adolescent with SHTG, DKA, and acute pancreatitis.

Abstract
Background: Patients with Myasthenia Gravis (MG) can be treated acutely with therapeutic plasma exchange (TPE) or intravenous immune globulin (IVIG). To date, there is no definitive understanding of which of the two treatments is more effective and safer. The purpose of this study was to systematically review the literature on the comparative efficacy and safety of TPE to other available treatments for MG. Methods: A systematic literature search for studies published between 1997 and 2017 was performed per Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines using two database sources, MEDLINE (through the PubMed database) and Cochrane Library. Results: The search strategy resulted in 535 articles whose abstracts were reviewed. Among these, 165 full texts articles were reviewed for eligibility and 101 articles were excluded. Of the 165 articles, 64 articles were included for a systematic literature and 11 articles for a meta-analysis. Conclusions: This systematic literature review and meta-analysis of treatment options showed that there was a higher response rate with TPE than IVIG in acute MG patients and patients undergoing thymectomy. There was no difference in mortality between the two treatment options. Our findings highlight the need for additional randomized clinical trials in these patients with MG.

Abstract
Severe acute respiratory syndrome corona virus-2 (SARS-CoV-2) due to novel coronavirus disease 2019 (COVID-19) has affected the global society in numerous unprecedented ways, with considerable morbidity and mortality. Both direct and indirect consequences from COVID-19 infection are recognized to give rise to cardio- and cerebrovascular complications. Despite current limited knowledge on COVID-19 pathogenesis, inflammation, endothelial dysfunction, and coagulopathy appear to play critical roles in COVID-19-associated cerebrovascular disease (CVD). One of the major subtypes of CVD is cerebral small vessel disease (CSVD) which represents a spectrum of pathological processes of various etiologies affecting the brain microcirculation that can trigger subsequent neuroinflammation and neurodegeneration. Prevalent with aging, CSVD is a recognized risk factor for stroke, vascular dementia, and Alzheimer's disease. In the background of COVID-19 infection, the heightened cellular activations from inflammations and oxidative stress may result in elevated levels of microthrombogenic extracellular-derived circulating microparticles (MPs). Consequently, MPs could act as pro-coagulant risk factor that may serve as microthrombi for the vulnerable microcirculation in the brain leading to CSVD manifestations. This review aims to appraise the accumulating body of evidence on the plausible impact of COVID-19 infection on the formation of microthrombogenic MPs that could lead to microthrombosis in CSVD manifestations, including occult CSVD which may last well beyond the pandemic era.

Abstract
A 70-year-old man with known cold autoimmune haemolytic anaemia was referred to the emergency department with increased shortness of breath on exertion. He had been confirmed positive for non-variant COVID-19 infection 1 week earlier based on nasopharyngeal swab PCR assay. CT thorax demonstrated diffuse patchy bilateral ground glass opacities, consistent with COVID-19 pneumonia. Bloodwork demonstrated severe cold agglutinin mediated haemolytic anaemia. To help stabilise the patient, he was transferred to a tertiary care hospital for urgent therapeutic plasma exchange. Key supportive therapy included folic acid supplementation, ensuring the patient was kept warm and warmed infusions including transfusions via the apheresis machine. The patient made a good recovery following plasma exchange, and his haemoglobin levels remained stable by discharge.

Abstract
A number of epidemiologic studies have demonstrated a strong association between increasing lipoprotein a [Lp(a)] and cardiovascular disease. This correlation was demonstrated independent of other known cardiovascular (CV) risk factors. Screening for Lp(a) in the general population is not recommended, although Lp(a) levels are predominantly genetically determined so a single assessment is needed to identify patients at risk. In 2019 ESC/EAS guidelines recommend Lp(a) measurement at least once a lifetime, fo subjects at very high and high CV risk and those with a family history of premature cardiovascular disease, to reclassify patients with borderline risk. As concerning medications, statins play a key role in lipid lowering therapy, but present poor efficacy on Lp(a) levels. Actually, treatment options for elevated serum levels of Lp(a) are very limited. Apheresis is the most effective and well tolerated treatment in patients with high levels of Lp(a). However, promising new therapies, in particular antisense oligonucleotides have showed to be able to significantly reduce Lp(a) in phase II RCT. This review provides an overview of the biology and epidemiology of Lp(a), with a view to future therapies.

Abstract
BACKGROUND Apheresis procedures require adequate vascular access to achieve optimal inlet flow rates. While central lines provide such access, their placement and use are associated with risks; some of these risks are minimized if peripheral intravenous access can be established. However, peripheral intravenous access is associated with challenges in the pediatric setting. Research indicates that midline catheters reduce the use of CVADs and their associated risks. The use of midline catheters for apheresis has been reported recently in adults, but no studies have been published on their use in children. Thus, the purpose of this study was to evaluate the use of midline catheters for apheresis in the pediatric setting. METHODS A retrospective observational study was conducted to evaluate the safety and efficacy of midline catheters in subjects who underwent apheresis at a pediatric hospital from April 2018 to August 2020. Demographic data, clinical data (diagnosis, procedure, catheter size, body mass), and outcome data (inlet flow rate, total blood volume [TBV] processed, procedure time, and cell counts) were collected. RESULTS Eighteen subjects received a total of 100 midline catheters for 73 apheresis procedures. Inlet flow rates ranged from 45 to 80 mL/min, TBV ranged from 2872 to 20 000 mL, and procedure time ranged from 1.25 to 7 hours. Inlet flow rates met or exceeded the recommended inlet flow rates for apheresis in children and adults (P < .0001). No adverse events occurred. CONCLUSION Midline catheters provide safe and effective vascular access for apheresis. Future research should include younger patients with lower body mass.

Abstract
Background Autoimmune hemolytic anemia (AIHA) is a rare disease characterized by hemolysis caused by autoantibodies against erythrocyte surface antigen. These antibodies can be classified as warm, cold, or mixed types. Methods We report two cases of cold agglutinin disease (CAD), which were eventually diagnosed owing to blood group discrepancy. Resolution was achieved after washing the red blood cells (RBCs) with warm saline and absorbing the autoantibodies at 4°C with the washed RBCs. We also assessed the patient's condition and discussed the strategy of blood transfusion. Results The first case occurred after postoperative chemotherapy for rectal cancer, and the other manifested with anemia from the outset. Direct antiglobulin tests were positive and revealed autoantibodies against C3d only. Cold agglutinin titration was performed, and the titers of both were 1:1024. Eventually, the patient's condition stabilized without blood transfusion. Conclusion The serological discrepancies observed in the blood transfusion department can successfully guide blood transfusion decisions in cases of CAD.

Abstract
Fibromyalgia syndrome (FMS) is characterized by widespread pain and tenderness, and patients typically experience fatigue and emotional distress. The etiology and pathophysiology of fibromyalgia are not fully explained and there are no effective drug treatments. Here we show that IgG from FMS patients produced sensory hypersensitivity by sensitizing nociceptive neurons. Mice treated with IgG from FMS patients displayed increased sensitivity to noxious mechanical and cold stimulation, and nociceptive fibers in skin-nerve preparations from mice treated with FMS IgG displayed an increased responsiveness to cold and mechanical stimulation. These mice also displayed reduced locomotor activity, reduced paw grip strength, and a loss of intraepidermal innervation. In contrast, transfer of IgG-depleted serum from FMS patients or IgG from healthy control subjects had no effect. Patient IgG did not activate naive sensory neurons directly. IgG from FMS patients labeled satellite glial cells and neurons in vivo and in vitro, as well as myelinated fiber tracts and a small number of macrophages and endothelial cells in mouse dorsal root ganglia (DRG), but no cells in the spinal cord. Furthermore, FMS IgG bound to human DRG. Our results demonstrate that IgG from FMS patients produces painful sensory hypersensitivities by sensitizing peripheral nociceptive afferents and suggest that therapies reducing patient IgG titers may be effective for fibromyalgia.

Abstract
Extracorporeal therapy is a treatment modality where human blood undergoes favorable technical modifications and is reintroduced into the same patient. Since the last four decades this technique has been deployed in the management of difficult and refractory disorders in dermatology. Over a period of time newer techniques like immunoadsorption has emerged and opened new vistas in management of morbid dermatoses. In extracorporeal photopheresis a patient's leukocytes are separated and treated outside with Ultra Violet A in presence of 8-methoxypsoralen. Double filtration plasmapheresis and Immunoadsorption are techniques to remove offending immune complexes. They are safe and reduce the need of toxic medications that are conventionally used in recalcitrant skin diseases. In recent years immunoadsorption is emerging as first-line therapy in condition like immunobullous diseases. High cost is one of the important factors limiting their wider use in developing countries like India. Our review discusses different extracorporeal therapies, their applications, recommendations and guidelines based on various clinical trials.

Pre-transplant donor-type red cell transfusion is a safe and effective strategy to reduce isohemagglutinin titers and prevent donor marrow infusion reactions in major ABO-mismatched transplants. Ann Hematol 2021; 100:2071-2078.

Abstract
ABO incompatibility is not a barrier to allogeneic stem cell transplant but may result in acute hemolytic reactions. As stem cell product manipulation is cumbersome, we are reporting the effectiveness and safety of donor-type red cell infusion as a method of reducing acute hemolytic reaction while using marrow as stem cell source. In major ABO-mismatched bone marrow transplants, manipulation of marrow product requires expertise and expensive equipment, which may not be readily available to transplant centers in low- and middle-income regions. The aim behind our study is to report a safe and effective strategy to reduce isohemagglutinin titers and prevent donor marrow infusion reactions in major ABO-mismatched transplants. We retrospectively analyzed 303 consecutive allogeneic bone marrow transplants (BMTs) for beta thalassemia major, between August 2015 and March 2020, with either major (n = 41) or bidirectional (n = 14) mismatches. When isohemagglutinin titers were 1:32 or higher, donor-type packed red blood cell was divided into 4 aliquots, irradiated and administered over 4 days at incremental volumes. Patients were observed for hemolytic reaction, and if no reaction, bone marrow was infused without manipulation. Out of 55 patients, 20 received donor-type blood infusion. Twelve patients showed evidence of mild hemolysis. None developed severe hemolytic or anaphylactic reaction. Titers were rechecked in 14 patients and all had reduction in titers, except for one. Our experience demonstrated that donor-type PRBC infusion is safe and effective in preventing acute hemolysis in major ABO-mismatched stem cell transplants even with bone marrow as graft source.

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
Introduction and importance Coronavirus Disease 2019 (COVID-19) has become a pandemic since the beginning of 2020. COVID-19 is also spreading very rapidly in Indonesia and so far, no definitive therapy has been found. Case presentation We report two cases of confirmed COVID-19 with moderate pneumonia, who received 400 ml of convalescent plasma and showed improvements in clinical, laboratory and radiological examinations. Clinical discussion Passive immunotherapy is generally more effective when given early. Plasma transfusion is more beneficial when given before clinical conditions become severe. Some studies have shown that therapy with convalescent plasma can contribute to a longer survival and a lower length of stay. Conclusion Convalescent plasma can be used as an adjunctive therapy option for patients with moderate COVID-19.

Abstract
Hepatitis B virus (HBV) chronic infection causes progressive liver damage, although about 20% of patients develop extrahepatic manifestations such as cryoglobulinemic vasculitis (CV). Clinical manifestations range from mild to moderate (purpura, asthenia, arthralgia) to severe (leg ulcers, peripheral neuropathy, glomerulonephritis, non-Hodgkin lymphoma). A comprehensive review of therapeutic options for HBV-related CV is lacking. Nucleos(t)ide analogues (NA) suppress HBV replication in 90–100% of cases and induce clinical response in most patients with mild-to-moderate CV. Plasma exchange can be performed in patients with severe CV and should be considered in severe or life-threatening cases combined with high doses of corticosteroids and antiviral treatment. A cautious use of rituximab can be considered only in association with NA treatment in refractory cases. A review of the literature and an analysis of data collected by six centers of the Italian Group for the Study of Cryoglobulinemia on 18 HBV-CV nucleotide/nucleoside analogues (NAs)-treated patients were carried out.

Abstract
Objective Primary outcome was to evaluate complete improvement at six months after acute treatment in NMOSD relapses. Methods Retrospective observational cohort study of patients with diagnosis of NMOSD admitted for acute attacks. We performed an explanatory analysis using the univariate, bivariate and multivariate logistic regression approach. We compared survival curves using the Kaplan Meier analysis and estimated the median time for the main outcome. Results In the univariate analysis, basal EDSS score, AQP4-IgG positivity, PLEX as a first-line treatment (IVMP + PLEX), less systemic complications related to acute treatment and total attack history were independently associated with complete improvement at six months. After adjusting for confounding variables and using multivariate analysis by Cox Regression, positive AQ4-IgG (HR 0.04, 95% CI: 0.02–0.66) and IVMP + PLEX (HR 5.1, 95% CI: 3.9–66.4), were kept as independent factors associated to time to complete improvement. Time from admission to PLEX initiation and complete improvement at six months had a median of seven days (95% CI: 5.2–8.8). In secondary effects, there were no statistical differences between the groups. Conclusions PLEX + IVMP is the treatment of choice for NMOSD relapses and should be initiated as early as possible.

Abstract
Shiga toxin-producing Escherichia coli-associated hemolytic uremic syndrome (STEC-HUS) is a form of thrombotic microangiopathy secondary to an infection by an enterohemorrhagic E. coli. Historically considered a pediatric disease, its presentation has been described as typical, with bloody diarrhea at the forefront. However, in adults, the clinical presentation is more diverse and makes the early diagnosis hazardous. In this review, we review the epidemiology, most important outbreaks, physiopathology, clinical presentation and prognosis of STEC-HUS, focusing on the differential features between pediatric and adult disease. We show that the clinical presentation of STEC-HUS in adults is far from typical and marked by the prevalence of neurological symptoms and a poorer prognosis. Of note, we highlight knowledge gaps and the need for studies dedicated to adult patients. The differences between pediatric and adult patients have implications for the treatment of this disease, which remains a public health threat and lack a specific treatment.

Abstract
Abstract
Background
Multiple organ dysfunction syndrome is the leading cause of death in pediatric intensive care units and can be very critical when combined with shock and disseminated intravascular coagulation (DIC). Currently, there is no effective treatment. We developed a new hemodiafiltration (HDF) method called plasma HDF (PHDF) that uses fresh frozen plasma as replacement fluid and investigated the safety and efficacy of this treatment.
Methods
We enrolled critically ill children with (1) a Pediatric Logistic Organ Dysfunction 2 (PELOD-2) score ≥ 14, (2) a Japanese Ministry of Health and Welfare (JMHW) DIC score ≥ 7, (3) a vasoactive inotropic score (VIS) ≥ 10, and (4) a serum total protein concentration ≤ 5.0 g/dL. PHDF was performed for 5 h and then switched to continuous HDF. The primary endpoint was the 28-day mortality rate. Secondary endpoints included assessment of vital signs, blood test data, and fluid balance from PHDF start to day 7.
Results
Nine patients (four males and five females) between 3 days and 40 months of age, weighing 2.1–13 kg, met the inclusion criteria. Although the median PMR was 0.94 (0.71–0.96), the 28-day mortality rate was 22.2% (2/9). One hour after the start of PHDF, there was an increase in mean arterial pressure and central venous pressure and a decrease in heart rate; by day 7, there was a significant decrease in the PELOD-2 score, the JMHW DIC score, and the VIS. Hypoproteinemia also improved the day after PHDF. Water balance was able to remain negative after day 2.
Conclusions
PHDF was found to be effective in the treatment of DIC and circulatory failure by supplementing coagulation and antithrombotic factors as well as by raising colloid osmotic pressure to increase circulating blood volume. PHDF has been shown to be a safe and useful treatment for critically ill children and has the potential to improve 28-day survival.

Abstract
Acute kidney injury (AKI) is common in patients with cancer, especially in those with haematological malignancies. Kidney injury might be a direct consequence of the underlying haematological condition. For example, in the case of lymphoma infiltration or extramedullary haematopoiesis, it might be caused by a tumour product; in the case of cast nephropathy it might be due to the presence of monoclonal immunoglobulin; or it might result from tumour complications, such as hypercalcaemia. Kidney injury might also be caused by cancer treatment, as many chemotherapeutic agents are nephrotoxic. High-intensity treatments, such as high-dose chemotherapy followed by haematopoietic stem cell transplantation, not only increase the risk of infection but can also cause AKI through various mechanisms, including viral nephropathies, engraftment syndrome and sinusoidal obstruction syndrome. Some conditions, such as thrombotic microangiopathy, might also result directly from the haematological condition or the treatment. Novel immunotherapies, such as immune checkpoint inhibitors and chimeric antigen receptor T cell therapy, can also be nephrotoxic. As new therapies for haematological malignancies with increased anti-tumour efficacy and reduced toxicity are developed, the number of patients receiving these treatments will increase. Clinicians must gain a good understanding of the different mechanisms of kidney injury associated with cancer to better care for these patients.

Abstract
Antithyroid drugs (ATDs) are the mainstay of treatment for Graves' disease with possible detrimental adverse effects. Surgery or radioactive iodine (RAI) ablation is the second choice among the treatment options in cases of non-remission. Normalization of serum thyroid hormone levels as much as possible is required before surgery or RAI to prevent thyrotoxic crisis in patients with uncontrolled Graves' disease. In recent decades, therapeutic plasma exchange (TPE) has been used in the treatment of thyroid storm, drug-induced hepatotoxicity and agranulocytosis, or patients with hyperthyroidism scheduled for emergency surgery. TPE is an effective method to reduce serum FT3, FT4, and TRAB levels in severe hyperthyroid conditions. Although TPE-related complications are rare, the risk of bleeding needs to be taken into consideration in patients who were scheduled for surgery within 24 h after TPE. In terms of reducing intraoperative bleeding, patients can be referred to surgery 24-48 h after TPE, or fresh frozen plasma transfusion can be the preferred treatment for emergency cases.

Abstract
INTRODUCTION Hyperthyroid patients who are unresponsive to medical treatment remain a challenging clinical problem. OBJECTIVE The goal of our study was to evaluate the use of therapeutic plasma exchange (TPE) in hyperthyroid patients and their outcome after TPE. METHOD We retrospectively reviewed 22 patients who underwent TPE for refractory thyrotoxicosis in our institution: 13 with Graves' disease, 7 with amiodarone-induced thyrotoxicosis (AIT), 1 with toxic goiter, and 1 pregnant patient with familial nonautoimmune thyrotoxicosis. RESULTS Before TPE, all patients had severe hyperthyroidism, and antithyroid drugs were either contraindicated or not sufficiently effective to restore euthyroidism promptly. After all the TPEs, free T4 (fT4) decreased significantly by 48% (p = 0.001) and fT3 by 52% (p = 0.0001). The median number of TPE sessions per patient was 4 (range: 1-10). There were no complications during the 91 TPE sessions. Total thyroidectomy with no severe side effects was performed on 16/22 patients and 1 other patient was treated with radioactive iodine. One patient died from severe thyrotoxicosis during medical care. The remaining 4 patients were followed up without any radical treatment. For all 7 patients with AIT, iterative TPE led to a significant clinical improvement, and amiodarone was continued for 1 patient. Available treatments were continued between TPE sessions (cholestyramine for 13 patients [60%] and glucocorticoids for 16 patients [73%]). CONCLUSION TPE allowed a safe decrease of 50% in thyroid hormone levels, and it should be considered for refractory hyperthyroid patients when medical treatments are contraindicated or have failed to restore euthyroidism, irrespective of the etiology of the thyrotoxicosis.

Abstract
A 33-year-old man with type 1 diabetes mellitus was admitted to the Internal Medicine Unit due to subacute onset of exertional dyspnea, with evidence at initial blood exams of severe macrocytic anemia with thrombocytopenia, biohumoral signs of hemolysis and 5 schistocytes per magnified field on the blood smear. A thrombotic microangiopathy (TMA) was suspected and plasma exchange (PEX) was started soon, since the risk of a life threatening condition. On the second day, after the results of A Disintegrin And Metalloproteinase with ThromboSpondin-1 motif, member 13 (ADAMTS-13) and reticulocytes were available, a critical reappraisal of the clinical scenario was done. B12 vitamin deficiency was evident after completing the diagnostic work-up. Finally, a diagnosis of "pseudo TMA vitamin B12 deficiency-related" was done. This is an intriguing and rare manifestation of cobalamin deficiency, given the very uncommon occurrence of schistocytes in this condition. "Pseudo TMA vitamin B12 deficiency-related" should be kept in mind when facing the differential diagnosis of microangiopathic anemia in the presence of a low proliferative index.

Abstract
Background Therapeutic plasma exchange (TPE) has been used increasingly to treat immunological diseases in dogs, although data concerning its efficacy are lacking. Hypothesis/Objectives To describe the clinic and the outcome of dogs with immune‐mediated hematological disorders (IMHD) treated with membrane filtration TPE. Animals One hundred forty‐six dogs diagnosed with IMHD, including 17 dogs treated with and 129 control dogs treated without TPE. Methods Retrospective study of cases selected with a search of all medical records for dogs diagnosed with IMHD (2010‐2019). Primary outcomes included the assessment of safety and efficacy of adjunctive TPE compared to medical treatment alone. Results The TPE group included 7 dogs with immune‐mediated hemolytic anemia (IMHA), 5 dogs with immune‐mediated thrombocytopenia (IMT), and 5 dogs with combined IMHA‐IMT; the control group included 63 dogs with IMHA, 47 dogs with IMT, and 19 dogs with IMHA‐IMT. Dogs treated with TPE were more often refractory to initial immunosuppression (71%) than controls (43%; P = .04). Complications were observed in 15/43 TPE treatments (35%). The response rate of dogs treated with TPE was 83% in IMHA (controls, 65%; P = .5) and 80% in IMT (controls, 70%; P = .71). Overall, 12/17 dogs (71%) treated with TPE reached complete remission, 2/17 (12%) partial remission, and 3/17 (18%) died or were euthanized. Eighty‐two percent of the dogs treated with TPE survived to discharge (controls, 69%; P = .4). Conclusions and Clinical Importance Despite a bias toward dogs refractory to initial immunosuppression, dogs treated with adjunctive TPE had a similar outcome as dogs treated medically.

Abstract
AbstractEvaluation of acquired demyelinating syndrome (ADS) without diagnostic biomarkers results in diagnostic and therapeutic challenges in pediatric population. Immune-mediated ADS of childhood responds well to steroid and intravenous immunoglobulin (IVIg) and in refractory cases with plasma exchange. Novel coronavirus disease 2019 (COVID-19) coinfection in such cases imposes technical challenges in management. An 11-year-old girl with quadriparesis and loss of vision and a magnetic resonance imaging (MRI) brain showing acute demyelinating encephalomyelitis (ADEM) and cerebrospinal fluid examination being noncontributory responded well with plasma exchange after failing steroid and IVIg is described. Coinfection with COVID-19 mandating personal protection in a temperate country imposed technical challenges in her management.

Abstract
Objective Severe hypertriglyceridemia carries increased health risks, including the development of pancreatitis. The objective of this study was to report on management of 2 cases with severe gestational hypertriglyceridemia. Cases In case 1, a 33-year-old pregnant woman presented with serum triglyceride level of 14 000 mg/dL after discontinuing hypolipidemic medications. She was treated with Lovaza 12 g/day, and serum triglyceride remained near normal at level of less than 800 mg mg/dL until delivery. In case 2, a 28-year-old patient (29th week gestation) presented with acute pancreatitis and triglycerides >4000 mg/dL. She was treated with Gemfibrozil, Lovaza, insulin infusion, subcutaneous heparin, and escalated to plasmapheresis. She successfully delivered a baby at the week of 36th and her triglyceride level was 304 mg/dL after that. Discussion Case 1 was treated with high-dose Lovaza and case 2 was treated with plasmapheresis successfully. Triglyceride levels were reduced to less than 500 mg/dL until delivery of healthy babies in both cases. Conclusion Omega-3 fatty acids and plasmapheresis may be effective and safe to treat pregnant women with severe hypertriglyceridemia and pancreatitis.

Abstract
Objective To assess through systematic review and meta-analysis whether plasma exchange (PE) is associated with prognosis in antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) patients. Methods A systematic search of PubMed, MEDLINE, Embase, and CENTRAL databases from inception to 17 June 2020 was conducted. Ongoing or unpublished trials were also searched in ClinicalTrials.gov and the World Health Organization trials portal. Randomised controlled trials (RCTs) comparing PE vs. non-PE in AAV patients (microscopic polyangiitis [MPA], granulomatosis with polyangiitis [GPA], or eosinophilic granulomatosis with polyangiitis [EGPA]) were included. The combined risk ratio (RR) was calculated by the random-effects model using the Mantel-Haenszel method. Heterogeneity was measured using the I2 statistic. Primary outcomes were mortality, clinical remission (CR), and adverse events (AEs). Results Four RCTs comparing PE vs. no PE (N = 827) and 1 RCT comparing PE vs. pulse steroid treatment (N = 137) were included. All participants were MPA or GPA patients (no EGPA patients). PE was not associated with main primary outcomes compared with no PE (mortality RR 0.93 [95% confidence interval {CI} 0.70–1.24], I2 = 0%; CR RR 1.02 [95% CI 0.91–1.15], I2 = 0%; and AE RR 1.10 [95% CI 0.73–1.68], I2 = 37%) or pulse steroid (mortality RR 0.99 [95% CI 0.71–1.37]; CR [the Birmingham Vasculitis Activity score] mean difference − 0.53 [95% CI − 1.40–0.34]; and AE RR 1.05 [95% CI 0.74–1.48]). Focusing on the early treatment phases, PE was associated with a reduction in end-stage renal disease incidence compared with both no PE (PE 1/43 vs. no PE 10/41; RR 0.14 [0.03–0.77] at 3 months) and pulse steroid (PE 11/70 vs. pulse steroid 23/67; RR 0.46 [0.24–0.86] at 3 months). Conclusion We carried out a systematic review and meta-analysis targeting all AAV patients, including MPA, GPA, and EGPA. In AAV patients, performing PE was not associated with the risk of mortality, CR, and AE. No RCT exists evaluating the efficacy of PE for EGPA; hence, this is required in the future. The results may affect the development of guidelines for AAV and may indicate the direction of future clinical research on AAV. Trial registration UMIN R000045239, PROSPERO CRD42020182566.

Artificial liver support system (ALSS) therapy is widely used in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). We aimed to develop a predictive score to identify the subgroups who may benefit from plasma exchange (PE)-centered ALSS therapy. A total of 601 patients were retrospectively enrolled and randomly divided into a derivation cohort of 303 patients and a validation cohort of 298 patients for logistic regression analysis, respectively. Five baseline variables, including liver cirrhosis, total bilirubin, international normalized ratio of prothrombin time, infection and hepatic encephalopathy, were found independently associated with 3-month mortality. A predictive PALS model and the simplified PALS score were developed. The predicative value of PALS score (AUROC = 0.818) to 3-month prognosis was as capable as PALS model (AUROC = 0.839), R score (AUROC = 0.824) and Yue-Meng’ score (AUROC = 0.810) (all p > 0.05), and superior to CART model (AUROC = 0.760) and MELD score (AUROC = 0.765) (all p < 0.05). The PALS score had significant linear correlation with 3-month mortality (R2 = 0.970, p = 0.000). PALS score of 0–2 had both sensitivity and negative predictive value of > 90% for 3-month mortality, while PALS score of 6–9 had both specificity and positive predictive value of > 90%. Patients with PALS score of 3–5 who received 3–5 sessions of ALSS therapy had much lower 3-month mortality than those who received 1–2 sessions (32.8% vs. 59.2%, p < 0.05). The more severe patients with PALS score of 6–9 could still benefit from ≥ 6 sessions of ALSS therapy compared to ≤ 2 sessions (63.6% vs. 97.0%, p < 0.05). The PALS score could predict prognosis reliably and conveniently. It could identify the subgroups who could benefit from PE-centered ALSS therapy, and suggest the reasonable sessions.

Total cholesterol concentration predicts the effect of plasmapheresis on hypertriglyceridemic acute pancreatitis: a retrospective case-control study. BMC Gastroenterol 2021; 21:3. [PMID: 33407166 PMCID: PMC7789165 DOI: 10.1186/s12876-020-01572-w] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/04/2020] [Accepted: 12/07/2020] [Indexed: 02/11/2023] Open
Abstract
Background What kind of patients with hypertriglyceridemic acute pancreatitis (HLAP) might benefit from plasmapheresis (PP) remains unknown. The objective of this study is to determine the predict function of total cholesterol (TC) on the Triglyceride (TG)-lowing effect in patients on either non-PP or PP therapy.
Methods Patients were categorized into high total cholesterol (HTC)/low total cholesterol (LTC) groups based on TC level of 12.4 mmol/L. The primary outcome was TG reduction to below 500 mg/dL within 48 h. Linear mixed-effect model and logistic regression analyses were used to assess the association of TC level and TG-lowing efficacy in different therapy groups. Results Compared with LTC group, patients with HTC showed more severe imaging manifestations (p < 0.001) and higher APACH II scores (p = 0.036). Deaths occurred only in HTC groups. Significant interaction of time sequence with the 2 TGs-lowing therapy groups on TG level was only found in HTC group (p < 0.001). In patients with elevated TC level, primary outcome occurred in 66.67% of patients in the PP group, and 27.91% in the non-PP group. After adjustment for age, gender, CT grade and APACH II score, the odd ratio remain significant (OR 5.47, 95% confidence interval [CI] 1.84–16.25, p = 0.002). Furthermore, in patients with lower TC level, no significant difference was found in primary outcome between PP group and non-PP group (81.25% versus 62.30%, adjusted OR 2.05; 95% CI 0.45–9.40; p = 0.353). Conclusions TC could be a potential biomarker to predict the effects of TG-lowing therapy in patients with HLAP.

Abstract
Therapeutic apheresis (TA) is prescribed to patients that suffer from a severe progressive disease that is not sufficiently treated by conventional medications. A way to gain more knowledge about this treatment is usually by the local analysis of data. However, the use of large quality assessment registries enables analyses of even rare findings. Here, we report some of the recent data from the World Apheresis Association (WAA) registry. Data from >104,000 procedures were documented, and TA was performed on >15,000 patients. The main indication for TA was the collection of autologous stem cells (45% of patients) as part of therapy for therapy. Collection of stem cells from donors for allogeneic transplantation was performed in 11% of patients. Patients with indications such as neurological diseases underwent plasma exchange (28%). Extracorporeal photochemotherapy, lipid apheresis, and antibody removal were other indications. Side effects recorded in the registry have decreased significantly over the years, with approximately only 10/10,000 procedures being interrupted for medical reasons. Conclusion Collection of data from TA procedures within a multinational and multicenter concept facilitates the improvement of treatment by enabling the analysis of and feedback on indications, procedures, effects, and side effects.

Abstract
BACKGROUND Lipoprotein apheresis (LA) is a safe method of reducing atherogenic lipoproteins and improving cardiovascular (CV) outcomes. We aimed to assess the reductions in low-density lipoprotein cholesterol (LDL-C) and lipoprotein (a) [Lp(a)] levels in patients undergoing regular LA therapy and to evaluate its influence on the incidence rate of adverse cardiac and vascular events (ACVE) and major adverse cardiac events (MACE). METHODS A longitudinal study in Poland evaluated the prospective and retrospective observational data of 23 patients with hyperlipoproteinaemia (a) [hyper-Lp(a)] and familial hypercholesterolemia (FH), undergoing 1014 LA sessions between 2013 and 2020. Their pre- and post-apheresis LDL-C and Lp(a) levels were assessed to calculate the acute percent reductions. The time period used to evaluate annual rates of ACVE and MACE before and after initiation of LA was matched in each patient. RESULTS The pre-apheresis LDL-C and Lp(a) concentrations were 155 (107-228) (mg/dL) (median and interquartile range) and 0.56 (0.14-1.37) (g/L), respectively. LA therapy resulted in a reduction of LDL-C to 50 (30-73.5) (mg/dL) and of Lp(a) to 0.13 (0.05-0.34) (g/L), representing a percent reduction of 70.0% and 72.7% for LDL-C and Lp(a), respectively. We found a significant reduction in the annual rate of ACVE (0.365[0.0-0.585] vs (0.0[0.0-0.265]; P = .047) and MACE (0.365[0.0-0.585] vs 0.0[0.0-0.265]; P = .031). CONCLUSIONS The findings of our study indicate that LA treatment in patients with hyperlipoproteinaemia (a) and FH on maximally tolerated lipid lowering therapies leads to a substantial reduction in LDL-C and Lp(a) concentrations and lowers CV event rates in Polish patients.

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
Acute pancreatitis complicated with pulmonary embolism has been described in literature, however, hyperlipidaemic acute pancreatitis complicated with pulmonary embolism and deep vein thrombosis has rarely been reported. We reported here a rare case of hyperlipidaemic acute pancreatitis. Although he had undergone plasmapheresis and his TG level reduced to normal range with symptoms relieved, he developed pulmonary embolism and multiple deep vein thromboses. The patient was diagnosed early and successfully salvaged by interventional radiology and oral anticoagulants. The patient was a 51-year-old man, he experienced a sudden upper abdomen pain for 24 h before being admitted to a local hospital where diagnosis of acute pancreatitis was made, and he had no relief of the symptoms after treatment. The patient was a non-smoker and did not consume alcohol. He had no history of diabetes, gallstones or cholelithasis. After transferring to our unit, the patient was treated with plasmapheresis along with low molecular weight heparin, insulin, antibiotics and proton pump inhibitors and the abdomen pain was alleviated gradually. However, 8 days after admission, the patient developed a sudden chest tightness and shortness of breath. Examination revealed a high level of D-dimer (16700 ug/L), a computer tomography angiography of chest revealed pulmonary embolism. Urokinase was started intravenously. Pulmonary angiography and venography demonstrated pulmonary embolism and extensive lower limb deep vein thrombosis. Catheter directed thrombolysis and urokinase was initiated through catheter followed by an IVC filter implantation. Dyspnea of the patient got well with thrombolytic treatment and anticoagulation therapy. This is a rare case of hyperlipidaemic acute pancreatitis complicated pulmonary embolism and Deep vein thrombosis even after treated with plasmapheresis. The case we present here will aid in its early recognition, interventional radiology hence the prevention for this rare but catastrophic complication.

Abstract
Aim and objective Pediatric acute liver failure (PALF) is a life-threatening condition. Extracorporeal support has been applied for toxic metabolite clearance and serves as a bridging therapy to liver transplantation (LT) or to the regeneration of the liver, but evidence for treatment approaches is still lacking in the pediatric population. We aim to report our experience on therapeutic plasma exchange with high-volume continuous renal replacement therapy (TPE + HV-CRRT) as a promising supportive treatment for PALF. Materials and methods A total of eight PALF cases aged 9 months to 14 years, weighing 10–50 kg., who were admitted to PICU King Chulalongkorn Memorial Hospital, Thailand and treated with TPE + HV-CRRT from January 2016 to September 2019 were reviewed. Patient demographic data, indications, technical aspects, and clinical outcomes were recorded. Results All patients who underwent TPE + HV-CRRT showed clinical improvement regarding serum bilirubin levels and coagulation studies after the therapy. Complications from the therapy were hemodynamic instability, symptomatic fluid overload, and bleeding from catheter sites. Among these, 6 (75%) patients survived with 4 (50%) successful LTs and 2 (25%) spontaneous recovery. Two children (25%) died while on the transplantation list. Conclusion TPE + HV-CRRT can be used safely as a bridging therapy in children with PALF. As opposed to the adult population, higher volume of TPE or higher blood flow rate in pediatric patients might associate with hemodynamic instability during the procedure.

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
Objective To investigate the therapeutic effects of a combination of plasma exchange (PE) and haemofiltration (HF) for the treatment for paediatric patients with severe thrombotic microangiopathy (TMA). Methods This retrospective study analysed data from paediatric patients who were diagnosed with severe TMA and managed with either supportive therapy and additional PE and HF (PE + HF group) or supportive therapy alone (control group). Demographic and clinical characteristics, haemopurification and blood parameters and survival of the patients were compared between the two groups. Results This study enrolled 32 patients: PE + HF group (n = 15) and control group (n = 17). There were no significant differences between the two groups at baseline, including specific features for differentiating the two categories of TMA. The median time between onset and recovery, defined by the markers of platelet count, lactate dehydrogenase, blood urine nitrogen and hospital stay, were all significantly longer in the control group compared with the PE + HF group. Kaplan–Meier curve analysis demonstrated that the cumulative survival rate was significantly higher in the PE + HF group compared with the control group. Conclusion The combination of PE and HF could be considered as one of the treatment choices for TMA.

AbstractHemolytic uremic syndrome (HUS) is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and acute kidney injury. Approximately 5% of HUS cases are associated with Streptococcus pneumoniae infections (pHUS). Treatment includes supportive care with appropriate antimicrobial therapy, fluid and blood product resuscitation, and renal replacement therapy. We presented a case of a 22-month-old previously healthy girl, who was hospitalized at University Hospital of Split. Left-sided pneumonia and sepsis caused by S. pneumoniae were confirmed. The course of illness was complicated with development of pHUS. Since the pathogenesis of pHUS is only partially understood, the treatment remains controversial. Our patient was successfully treated with daily sequence tandem continuous venovenous hemodiafiltration and therapeutic plasma exchange with albumins, along with other supportive measures. Therefore, in our opinion, plasmapheresis should be considered as a part of standard treatment of children with pHUS. Additionally, the incidence of pHUS appears to be increasing. S. pneumoniae is a particularly important among pediatric pathogens and it can cause wide spectrum of illnesses. Therefore, due to the significant burden of invasive pneumococcal disease, pneumococcal vaccination should be encouraged.

Rh Alloimmunisation: Current Updates in Antenatal and Postnatal Management. Indian J Pediatr 2020; 87:1018-1028.

Abstract
In spite of advances in medical science, Rh alloimmunisation remains one of the leading causes of preventable neuro-morbidities and significant neonatal hyperbilirubinemia in lower-middle income countries. Despite availability of effective antenatal preventive strategy (Anti-D), its uptake in antenatal period is low due to ignorance. Further, once diagnosed, there is lack of adequate antenatal follow up in health care facility. Some of these cases even remain undiagnosed in antenatal period only to present as a case of severe hyperbilirubinemia and kernicterus in late neonatal period. Thus, there is an urgent need for creating awareness and educating health care professionals for early detection and timely management in both antenatal and postnatal period. Following two doses of anti-D prophylaxis (one in antenatal period and one in immediate postnatal period) the incidence of Rh alloimmunisation can reduce to <1%. It is recommended to follow all Rh alloimmunised pregnancies antenatally with serial indirect Coombs test titre (till critical titre is reached) followed by serial Doppler velocimetry of middle cerebral artery in a perinatal centre where facility for intrauterine transfusion as well as advanced neonatal care is available. Postnatal management of these infants comprises of confirmation of diagnosis, aggressive phototherapy and in selective cases, double volume exchange transfusion. With appropriate antenatal and postnatal management, the prognosis of Rh alloimmunised pregnancy remains favourable and long term outcome of Rh alloimmunised infants remain comparable with their normal counterparts.

New Insights in Autoimmune Hemolytic Anemia: From Pathogenesis to Therapy Stage 1. J Clin Med 2020; 9:jcm9123859. [PMID: 33261023 PMCID: PMC7759854 DOI: 10.3390/jcm9123859] [Citation(s) in RCA: 49] [Impact Index Per Article: 12.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/03/2020] [Revised: 11/20/2020] [Accepted: 11/24/2020] [Indexed: 12/15/2022] Open
Abstract
Autoimmune hemolytic anemia (AIHA) is a highly heterogeneous disease due to increased destruction of autologous erythrocytes by autoantibodies with or without complement involvement. Other pathogenic mechanisms include hyper-activation of cellular immune effectors, cytokine dysregulation, and ineffective marrow compensation. AIHAs may be primary or associated with lymphoproliferative and autoimmune diseases, infections, immunodeficiencies, solid tumors, transplants, and drugs. The direct antiglobulin test is the cornerstone of diagnosis, allowing the distinction into warm forms (wAIHA), cold agglutinin disease (CAD), and other more rare forms. The immunologic mechanisms responsible for erythrocyte destruction in the various AIHAs are different and therefore therapy is quite dissimilar. In wAIHA, steroids represent first line therapy, followed by rituximab and splenectomy. Conventional immunosuppressive drugs (azathioprine, cyclophosphamide, cyclosporine) are now considered the third line. In CAD, steroids are useful only at high/unacceptable doses and splenectomy is uneffective. Rituximab is advised in first line therapy, followed by rituximab plus bendamustine and bortezomib. Several new drugs are under development including B-cell directed therapies (ibrutinib, venetoclax, parsaclisib) and inhibitors of complement (sutimlimab, pegcetacoplan), spleen tyrosine kinases (fostamatinib), or neonatal Fc receptor. Here, a comprehensive review of the main clinical characteristics, diagnosis, and pathogenic mechanisms of AIHA are provided, along with classic and new therapeutic approaches.

Abstract
Autoimmune hemolytic anemia (AIHA) is an acquired, heterogeneous group of diseases which includes warm AIHA, cold agglutinin disease (CAD), mixed AIHA, paroxysmal cold hemoglobinuria and atypical AIHA. Currently CAD is defined as a chronic, clonal lymphoproliferative disorder, while the presence of cold agglutinins underlying other diseases is known as cold agglutinin syndrome. AIHA is mediated by autoantibodies directed against red blood cells (RBCs) causing premature erythrocyte destruction. The pathogenesis of AIHA is complex and still not fully understood. Recent studies indicate the involvement of T and B cell dysregulation, reduced CD4+ and CD25+ Tregs, increased clonal expansions of CD8 + T cells, imbalance of Th17/Tregs and Tfh/Tfr, and impaired lymphocyte apoptosis. Changes in some RBC membrane structures, under the influence of mechanical stimuli or oxidative stress, may promote autohemolysis. The clinical presentation and treatment of AIHA are influenced by many factors, including the type of AIHA, degree of hemolysis, underlying diseases, presence of concomitant comorbidities, bone marrow compensatory abilities and the presence of fibrosis and dyserthropoiesis. The main treatment for AIHA is based on the inhibition of autoantibody production by mono- or combination therapy using GKS and/or rituximab and, rarely, immunosuppressive drugs or immunomodulators. Reduction of erythrocyte destruction via splenectomy is currently the third line of treatment for warm AIHA. Supportive treatment including vitamin supplementation, recombinant erythropoietin, thrombosis prophylaxis and the prevention and treatment of infections is essential. New groups of drugs that inhibit immune responses at various levels are being developed intensively, including inhibition of antibody-mediated RBCs phagocytosis, inhibition of B cell and plasma cell frequency and activity, inhibition of IgG recycling, immunomodulation of T lymphocytes function, and complement cascade inhibition. Recent studies have brought about changes in classification and progress in understanding the pathogenesis and treatment of AIHA, although there are still many issues to be resolved, particularly concerning the impact of age-associated changes to immunity.

Abstract
INTRODUCTION Hepatitis C virus (HCV) infection affects about 170 million people worldwide. HCV is responsible for both hepatitis and extra-hepatic manifestations. Chronic infection has been shown to develop in about 70% of cases, and it can progress to cirrhosis or hepatocellular carcinoma. Ten percent of HCV patients may develop extra-hepatic manifestations, including mixed cryoglobulinemia (MC) and non-Hodgkin lymphomas (NHL). Cryoglobulinemic vasculitis (CV) varies, ranging from mild-moderate clinical symptoms (purpura on the legs, asthenia and arthralgias) and chronic hepatitis to severe symptoms (ulcers on the legs, peripheral neuropathy, glomerulonephritis, low-grade NHL to life threatening complications (rapid progressive glomerulonephritis, gastrointestinal vasculitis, acute hyper-viscosity). EVIDENCE ACQUISITION CV is associated with significant morbidity and mortality. Some studies have shown kidney involvement, cirrhosis, central nervous system involvement, and heart involvement as unfavorable prognostic factors. Many studies have demonstrated that, after antiviral therapy, CV can disappear along with HCV. After the introduction of the new direct antiviral agents (DAAs), the combination of pegylated interferon and ribavirin has been abandoned. EVIDENCE SYNTHESIS Several studies on new DAAs have reported remarkable 90% to 100% HCV eradication rates, regardless of genotype. Treatment with DAAs has comparable efficacy on viral eradication in CV patients but definite clinical improvements of vasculitis can be observed only in half the patients. CONCLUSIONS In patients with mild to moderate CV disease, DAAs therapy should be used as first line approach. In patients with severe vasculitis, DAAs therapy and a second-line treatment with RTX with or without aphaeresis are a required.

Abstract
Calciphylaxis is a rare and severe condition, characterized by calcification and thrombosis of small vessels, mainly affecting the skin. It is most often described in patients with end-stage renal disease on dialysis. Rarer cases of non-uremic calciphylaxis are reported. The prognosis is grim and the treatment is not well codified. Sodium thiosulfate has been used for more than a decade in the treatment of uremic calciphylaxis and has been shown to be effective. Its use in non-uremic cases has been reported in a few rare observations. Rheopheresis is a technique very recently used as an adjuvant treatment in uremic calciphylaxis. We describe a case of non-uremic calciphylaxis in a patient with normal renal function and with calcium supplementation. Sodium thiosulfate was introduced, then discontinued due to the patient's poor tolerance for this treatment. Rheopheresis was then used and allowed the acceleration of healing process and a significant reduction in pain. These two treatments are promising, larger studies are needed to establish their effectiveness in non-uremic calciphylaxis.

Abstract
There are several reports in medical literature about Red Cell Exchange (RCE) being routinely performed pre-operatively in sickle cell disease patients to provide immediate decrease in HbS concentration and prevent post-operative complications. We would like to present one such case of SCD who also had multiple allo-antibodies and had to undergo hemi-arthroplasty for avascular necrosis of head femur. Grouping and antibody screening was performed using column agglutination technique. 3-cell and 11- cell panel were used for antibody screening and identification, respectively. Automated RBC exchange was performed on apheresis machine Com. Tec using the standard PL1 kit (Fresenius Kabi, Germany). Multiple (anti-c, E) allo-antibodies were identified and successful pre-operative RCE was done with corresponding antigen-negative AHG compatible RBC units. Single RCE procedure reduced HbS concentration from 65% to 25%. The patient underwent uneventful hemi-arthroplasty and was discharged on post-operative day-7. Patient is on regular follow-up and continues to do well two months after the day of surgery. This is possibly the first case report from India, which illustrates successful automated RCE in a SCD patient with alloimmunization.

Abstract
Fetal therapy has been defined as any therapeutic intervention either invasive or noninvasive for correcting or treating any fetal malformation or condition. Invasive fetal therapy have its own set of maternal and fetal complications and invasive approach is not feasible in many of fetal conditions that are candidate for fetal therapy. Many such fetal conditions have been treated successfully by medical or noninvasive management. In medical fetal therapy, mothers are treated with medications which are transferred to fetus through placenta and exert positive effect on the fetus, thus avoiding complications that are seen secondary to invasive fetal therapy. The fetal conditions that have been managed with medical therapy includes fetal and neonatal alloimmune thrombocytopenia, neural tube defect, congenital adrenal hyperplasia, perinatal infections, respiratory distress syndrome, inborn error of metabolism, and congenital cystic adenomatoid malformation. This review will cover the medical or noninvasive aspect of fetal therapy and will highlight the progress made in the management of these fetal conditions.

Abstract
Fetal therapy term has been described for any therapeutic intervention either invasive or noninvasive for the purpose of correcting or treating any fetal malformation or condition. Fetal therapy is a rapidly evolving specialty and has gained pace in last two decades and now fetal intervention is being tried in many malformations with rate of success varying with the type of different fetal conditions. The advances in imaging techniques have allowed fetal medicine persons to make earlier and accurate diagnosis of numerous fetal anomalies. Still many fetal anomalies are managed postnatally because the fetal outcomes have not changed significantly with the use of fetal therapy and this approach avoids unnecessary maternal risk secondary to inutero intervention. The short-term maternal risk associated with fetal surgery includes preterm labor, premature rupture of membranes, uterine wall bleeding, chorioamniotic separation, placental abruption, chorioamnionitis, and anesthesia risk. Whereas, maternal long-term complications include risk of infertility, uterine rupture, and need for cesarean section in future pregnancies. The decision for invasive fetal therapy should be taken after discussion with parents about the various aspects like postnatal fetal outcome without fetal intervention, possible outcome if the fetal intervention is done, available postnatal intervention for the fetal condition, and possible short-term and long-term maternal complications. The center where fetal intervention is done should have facility of multi-disciplinary team to manage both maternal and fetal complications. The major issues in the development of fetal surgery include selection of patient for intervention, crafting effective fetal surgical skills, requirement of regular fetal and uterine monitoring, effective tocolysis, and minimizing fetal and maternal fetal risks. This review will cover the surgical or invasive aspect of fetal therapy with available evidence and will highlight the progress made in the management of fetal malformations in last two decades.
