Abstract
Autoimmune hemolytic anemia (AIHA) is characterized by hemolysis caused by autoantibodies. However, many patients do not respond to therapies and may have an unfavorable outcome. It has been hypothesized that patients with AIHA and alloantibodies have a lower survival compared to patients with this disease and without alloimmunization. To this end, the clinical and laboratory profile was described and sought to identify features associated with survival in patients with AIHA. This is a single-site retrospective observational study that included patients (children, adolescents, adults and elderly) diagnosed with AIHA from January 2000 to June 2019. Epidemiological data, laboratory tests, treatment response, alloantibody and autoantibody profile, red cell transfusion and clinical course were analyzed. Survival analysis was performed using Kaplan-Meier curves and Cox proportional hazards regression. The study included 138 patients, mostly caucasians and female. The median age at diagnosis was 48.5 years (0.16-88) and 82 (59.4 %) patients had secondary AIHA. In addition, 33 % (25/75) of subjects had alloantibodies at the time of AIHA diagnosis and 40 % (16/40) detected alloantibody emergence later. The overall 10-year survival rate was 51 % (median follow-up was 39 months). Monocytosis, IgM class autoantibody and Direct Antiglobulin Test (DAT) intensity had a significant impact on predicting mortality in this population. On the other hand, alloimmunization at diagnosis and after did not affect survival in this population.

Abstract
Autoimmune hemolytic anemia (AIHA) is an acquired hemolytic disorder, mediated by auto-antibodies, and has a variable clinical course ranging from fully compensated low grade hemolysis to severe life-threatening cases. The rarity, heterogeneity and incomplete understanding of severe AIHA complicate the recognition and management of severe cases. In this review, we describe how severe AIHA can be defined and what is currently known of the severity and outcome of AIHA. There are no validated predictors for severe clinical course, but certain risk factors for poor outcomes (hospitalisation, transfusion need and mortality) can aid in recognizing severe cases. Some serological subtypes of AIHA (warm AIHA with complement positive DAT, mixed, atypical) are associated with lower hemoglobin levels, higher transfusion need and mortality. Currently, there is no evidence-based therapeutic approach for severe AIHA. We provide a general approach for the management of severe AIHA patients, incorporating monitoring, supportive measures and therapeutic options based on expert opinion. In cases where steroids fail, there is a lack of rapidly effective therapeutic options. In this era, numerous novel therapies are emerging for AIHA, including novel complement inhibitors, such as sutimlimab. Their potential in severe AIHA is discussed. Future research efforts are needed to gain a clearer picture of severe AIHA and develop prediction models for severe disease course. It is crucial to incorporate not only clinical characteristics but also biomarkers that are associated with pathophysiological differences and severity, to enhance the accuracy of prediction models and facilitate the selection of the optimal therapeutic approach. Future clinical trials should prioritize the inclusion of severe AIHA patients, particularly in the quest for rapidly acting novel agents.

Abstract
Objective Patients with autoimmune hemolytic anemia (AIHA) are considered to be at an increased risk of thrombosis, and prophylaxis for venous thromboembolism (VTE) is often recommended. However, the occurrence of thrombosis in Asian patients has not been specifically studied. Thrombotic complications and features of Japanese warm AIHA (WAIHA) patients were studied to see if Japanese patients were at an increased risk of thrombosis and should receive prophylaxis for VTE. Patients and Methods Forty-seven consecutive patients with warm WAIHA were retrospectively studied. Twenty-nine patients were diagnosed as primary cases and 18 as secondary cases, and 10 patients were diagnosed with Evans syndrome. Results No patient presented with thrombosis, and over a median observation period of 15 months, 3 patients had ischemic cerebral vascular accidents. However, all three of those patients had other known risks for thrombosis, with only one taking thrombotic prophylaxis. No venous thrombosis occurred in any patients during the follow-up period. There was no mortality associated with thrombosis. D-dimer levels were often elevated in patients with WAIHA, indicating that the coagulation was activated in a considerable number of patients, but not to such a level as to be associated with clinically overt thrombosis. Conclusion Thrombotic complications occur infrequently in Japanese WAIHA patients, and these individuals do not appear to be at a particularly increased risk of thrombosis because of WAIHA. The indication of VTE prophylaxis should be determined individually, considering other risks.

Abstract
Introduction Autoimmune hemolytic anemia (AIHA) is considered a chronic disease, with an overall good prognosis. However, recent reports indicate pre‐mature mortality. Causes of death have not been evaluated previously. Methods In a nationwide setting, we identified all patients with warm type AIHA or cold agglutinin disease (CAD), and age–sex‐matched comparators from Denmark, 1980–2016. We estimated overall survival and cause‐specific mortality from anemia, infection, cardiovascular causes, hematological or solid cancer, bleeding, or other causes, using cumulative incidence proportions. Results We identified 1460 patients with primary AIHA, 1078 with secondary AIHA, 112 with CAD, and 130 801 comparators. One‐year survival and median survival were, 82.7% and 9.8 years for primary AIHA, 69.1% and 3.3 years for secondary AIHA, and 85.5% and 8.8 years for CAD. Prognosis was comparable to the general population only in patients with primary AIHA below 30 years. In all other age and subgroups, the difference was considerable. Cumulated cause‐specific mortality at 1 year was increased among patients versus comparators. Discussion All groups of autoimmune hemolytic anemia are associated with increased overall and cause‐specific mortality compared to the general population. This probably reflects unmet needs in both treatment and follow‐up programs.

Abstract
INTRODUCTION Autoimmune hemolytic anemia (AIHA) is classified according to the direct antiglobulin test (DAT) and thermal characteristics of the autoantibody into warm and cold forms, and in primary versus secondary depending on the presence of associated conditions. AREAS COVERED AIHA displays a multifactorial pathogenesis, including genetic (association with congenital conditions and certain mutations), environmental (drugs, infections, including SARS-CoV-2, pollution, etc.), and miscellaneous factors (solid/hematologic neoplasms, systemic autoimmune diseases, etc.) contributing to tolerance breakdown. Several mechanisms, such as autoantibody production, complement activation, monocyte/macrophage phagocytosis, and bone marrow compensation are implicated in extra-/intravascular hemolysis. Treatment should be differentiated and sequenced according to AIHA type (i.e. steroids followed by rituximab for warm, rituximab alone or in association with bendamustine or fludarabine for cold forms). Several new drugs targeting B-cells/plasma cells, complement, and phagocytosis are in clinical trials. Finally, thrombosis and infections may complicate disease course burdening quality of life and increasing mortality. EXPERT OPINION Beyond warm and cold AIHA, a gray-zone still exists including mixed and DAT negative forms representing an unmet need. AIHA management is rapidly changing through an increasing knowledge of the pathogenic mechanisms, the refinement of diagnostic tools, and the development of novel targeted and combination therapies.

Abstract
Background: Warm autoimmune haemolytic anaemia (wAIHA) is a haemolytic disorder, most commonly seen among adults and is classified as either primary or secondary to an underlying disease. We describe the age and sex distribution and the proportion of secondary wAIHA. Method: We retrieved 2635 published articles, screened abstracts and titles, and identified 27 articles eligible for full-text review. From these studies, we extracted data regarding number of patients, sex distribution, age at diagnosis, number of patients with secondary wAIHA, and whether the patients were diagnosed through local or referral centres. All data were weighted according to the number of included patients in each study. Results: 27 studies including a total of 4311 patients with wAIHA, of which 66% were females, were included. The median age at diagnosis was 68.7 years, however, wAIHA affected all ages. The mean proportion of secondary wAIHA was 49%, most frequently secondary to systemic lupus erythematosus. The proportions of secondary wAIHA reported from primary vs. referral centres were 35% vs. 59%, respectively. Conclusion: This review consolidates previously reported gender distribution. The higher proportion of secondary wAIHA in referral centres suggests that the most severely affected patients are disproportionally more frequent in such facilities.

Abstract
Warm autoimmune hemolytic anemia (wAIHA) is caused by increased erythrocyte destruction by immunoglobulin G (IgG) autoantibodies, with or without complement activation. Antibody-dependent cell-mediated cytotoxicity by macrophages/activated lymphocytes occurs in the lymphoid organs and spleen (extravascular hemolysis). The ability of the bone marrow (BM) to compensate determines clinical severity. The different pathogenic mechanisms, their complex interplay, and changes over time may explain wAIHA's great clinical heterogeneity and unpredictable course. The disease may be primary, drug induced, or associated with lymphoproliferative neoplasms, autoimmune and infectious diseases, immunodeficiencies, solid tumors, or transplants. Therapeutic interventions include steroids, splenectomy, immunosuppressants, and rituximab; the latter is increasingly used in steroid-refractory cases based on evidence from the literature and a few prospective trials. We present 5 patient case studies highlighting important issues: (1) the diagnosis and proper use of steroid therapy, (2) the concerns about the choice between rituximab and splenectomy in second-line treatment, (3) the need of periodical re-evaluation of the disease to assess the possible evolution of relapsed/refractory cases in myelodysplastic and BM failure syndromes, and (4) the difficulties in managing cases of severe/acute disease that are at high risk of relapse. Incorporating novel targeted therapies into clinical practice will be an exciting challenge in the future.

Abstract
Autoimmune hemolytic anemia (AIHA) may be frequently challenged by infectious complications, mainly as a result of immunosuppressive treatments administered. Furthermore, infectious agents are known triggers of AIHA onset and relapse. Although being risk factors for mortality, infections are an underestimated issue in AIHA. This review will collect the available evidence on the frequency and type of infectious complications in AIHA, detailing the risk related to each treatment (i.e., steroids, rituximab, splenectomy, classic immunosuppressive agents, and new target drugs). Moreover, we will briefly discuss the infectious complications in AIHA secondary to other diseases that harbor an intrinsic infectious risk (e.g., primary immunodeficiencies, systemic autoimmune diseases, lymphoproliferative disorders, solid organ and hematopoietic stem cell transplants). Finally, viral and bacterial reactivations during immune suppressive therapies will be discussed, along with suggested screening and prophylactic strategies.

Abstract
BACKGROUND Rheumatic diseases have many hematological manifestations. Blood dyscrasias and other hematological abnormalities are sometimes the first sign of rheumatic disease. In addition, novel antirheumatic biological agents may cause cytopenias. SUMMARY The aim of this review was to discuss cytopenias caused by systemic lupus erythematosus and antirheumatic drugs, Felty's syndrome in rheumatoid arthritis, and autoimmune hemolytic anemia, thrombosis, and thrombotic microangiopathies related to rheumatological conditions such as catastrophic antiphospholipid syndrome and scleroderma renal crisis. Key Message: The differential diagnosis of various hematological disorders should include rheumatic autoimmune diseases among other causes of blood cell and hemostasis abnormalities. It is crucial that hematologists be aware of these presentations so that they are diagnosed and treated in a timely manner.

Abstract
INTRODUCTION Autoimmune hemolytic anemia (AIHA) is due to autoantibodies against erythrocytes that may arise either because of primary tolerance breakage or along with several associated conditions, including genetic predispositions, congenital syndromes, environmental triggers, autoimmune diseases, immunodeficiencies, and neoplasms. AREAS COVERED This review evaluated the risk of AIHA development in associated conditions and summarized disease-intrinsic risk factors for relapse and outcome. Diagnostic procedures were analyzed to properly identify primary and secondary forms. A Medline including clinical trials, meta-analyses, guidelines, consensus, and case reports, published in the last 30 years were performed. EXPERT OPINION The several associated conditions listed above constitute a risk for AIHA development and should be considered since disease course and therapy may be different. Particularly, AIHA developing after transplant or novel checkpoint inhibitors is an emerging complex entity whose proper therapy is still an unmet need. Concerning intrinsic risk factors, the severity of anemia at onset correlated with the recurrence of relapses, refractoriness, and fatal outcome. This finding reflects the presence of several mechanisms involved in AIHA, i.e. highly pathogenic antibodies, complement activation, and failure of marrow compensation. With the advent of novel target therapies (complement and various tyrosine kinase inhibitors), a risk-adapted therapy for AIHA is becoming fundamental.

Abstract
Autoimmune hemolytic anemia (AIHA) is a rare disease in which autoantibodies target red blood cells (RBCs), leading to anemia that ranges from no symptoms to severe life-threatening hemolysis. Little is known about the severity of anemia, blood transfusion efficiency and risk of transfusion-related reactions among hospitalized AIHA patients, especially in those with incompatible RBC transfusions.A retrospective study was conducted among hospitalized AIHA patients from January 2009 to December 2015 in a large tertiary care medical center in southwest China.A total of 450 AIHA hospitalized patients were recruited, of whom 97.3% had warm AIHA, 30.3% had primary AIHA, and 90.7% were treated with corticosteroids. On admission, approximately 3% of patients had an hemoglobin (Hb) <30 g/L, 34% had an Hb between 30 and 59.9 g/L, and 46% had an Hb ranging from 60 to 89.9 g/L. A total of 2509.5 U RBCs were transfused to AIHA patients, and 14 transfusion-related adverse reactions were recorded, without any hemolytic transfusion reactions. With an average transfusion trigger of 52.0 ± 9.3 g/L, 59.7% of the patients received RBCs, and 55.8% of the transfusions were viewed as effective. Least incompatible RBCs were given in 39% of the transfusions, but the transfusion efficiency did not significantly decrease with these incompatible blood transfusions (P = .253). Primary AIHA patients with a nadir Hb of approximately 40 to 50 g/L during their hospital stay had the highest rate of remission and did not require a different total number of RBC transfusions (P = .068) or length of hospitalization (P = .194) compared to other groups with nadir Hb values <30 g/L, ≥30 and <40 g/L, ≥50 and <60 g/L, and ≥60 g/L.One-third of AIHA patients suffered from severe anemia during hospitalization, and transfusions, even with incompatible RBCs, were safe and efficient. However, transfusion triggers between 40 and 50 g/L seemed to benefit the most patients by alleviating the RBC destruction caused by autoantibodies, and a restrictive transfusion strategy was beneficial in AIHA patients.

Abstract
Objectives:: To investigate the efficacy and safety of second-line treatment in Thai patients with primary warm-type autoimmune hemolytic anemia (AIHA) that failed corticosteroid treatment. Methods:: This descriptive retrospective study included patients aged >14 years who were diagnosed with and treated for primary warm-type AIHA at the Division of Hematology, Department of Medicine, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand, during January 2007 to December 2016. All 54 included patients failed first-line corticosteroid treatment after which second-line treatment was prescribed. Baseline clinical characteristics, laboratory results at diagnosis and at start of second-line treatment, type of second-line treatment, treatment outcome, and complications of treatment including death were collected. Results:: Included patients had a mean age at onset of 55.8 years (14.5-87.4) and 83.3% of patients were female. Most patients (63%) were refractory to steroids, and the rest of them relapsed while on steroids. The second-line medications were azathioprine (61.1%), cyclophosphamide (31.5%), chlorambucil (1.9%), danazol (3.7%), and rituximab (1.9%), with respective response rates of 78.8%, 58.8%, 1/1 patient, 2/2 patients, and 0/1 patient. Strong positive direct Coombs' test (3+-4+) was the only predictive factor of treatment response (p = 0.008). Males had better relapse-free survival than females (not reached vs. 20.6 months) (p = 0.023). Approximately 40% of the patients who responded to second-line treatment relapsed at a median of 7.4 months. Conclusion:: Immunosuppressive drugs are the most common second-line treatment for primary warm-type AIHA in Thailand; however, relapse was common. Additional therapies are needed to reduce the relapse rate and prolong remission.

Autoimmune hemolytic anemia after allogeneic hematopoietic stem cell transplantation in adults: A southern China multicenter experience. Cancer Med 2019; 8:6549-6558. [PMID: 31502764 PMCID: PMC6825994 DOI: 10.1002/cam4.2539] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/04/2019] [Revised: 08/22/2019] [Accepted: 08/22/2019] [Indexed: 01/06/2023] Open
Abstract
To investigate the incidence and risk factors as well as prognosis of autoimmune hemolytic anemia (AIHA) following allogeneic hematopoietic stem cell transplantation (allo‐HSCT), a total of 1377 adult hematological malignancies at three institutions were enrolled in this study. The 3‐year cumulative incidence of AIHA was 2.2 ± 0.4%. Multivariate analysis showed that haploidentical donors (HRDs) and chronic graft vs host disease (cGVHD) were the independent risk factors for AIHA. Patients with AIHA treated initially with corticosteroids combined with cyclosporine A (CsA) had a higher complete response rate than those with corticosteroids monotherapy (66.7% vs 11.1%; P = .013). The 3‐year cumulative incidence of malignant diseases relapse was 4.4 ± 4.3% and 28.0 ± 1.3% (P = .013), treatment‐related mortality (TRM) was 8.9 ± 6.3% and 17.4 ± 1.2% (P = .431), disease‐free survival (DFS) was 56.1 ± 1.5% and 86.7 ± 7.2% (P = .011), and overall survival (OS) was 86.3 ± 7.4% and 64.1 ± 1.5% (P = .054), respectively, in the patients with AIHA and those without AIHA. Our results indicate that HRDs and cGVHD are risk factors for AIHA and corticosteroids combined with CsA are superior to corticosteroids as initial treatment for AIHA. Autoimmune hemolytic anemia does not contribute to increase TRM and could reduce the malignant diseases relapse and increase DFS.

Clinical Features and Treatment Outcomes of Warm Autoimmune Hemolytic Anemia: A Retrospective Analysis of 60 Turkish Patients. Indian J Hematol Blood Transfus 2019; 35:523-530.

Abstract
We aimed to analyze 10-year experience of WAIHA patients at a single referral center in Turkey. Clinical data, survival outcome of sixty patients who were diagnosed with WAIHA were retrospectively analyzed. All the patients were direct antiglobulin test (DAT) positive. In 21 (30%) patients, IgG plus C3d DAT positivity was documented. 16 patients were secondary WAIHA and most common underlying causes were lymphoproliferative diseases (5 patients) and connective tissue disease (8 patients). Corticosteroids were first choice as a first line therapy with 54.5% CR and 40.2% PR rates. 43.3% of the patients relapsed after a median 12 months. In relapsed patients, rituximab and splenectomy achieved 85% overall response rates. The median OS was not reached. The median DFS was 40 months (95% CI, 19.6-60.4). OS and DFS at 36 months were 89.6% and 51.1%, respectively. DFS at 36 months was lower in patients with IgG plus C3d positive DAT than patients with only positive Ig G DAT (36 vs. 54%) but this difference could not reach statistical significance (p = 0.23). WAIHA was a rare disease with a good prognosis. Corticosteroids were the first option and splenectomy and rituximab received good responses in relapsed patients. Attention should be paid especially in patients with IgG plus C3d DAT positivity since lower DFS were reported. Characteristics and pathogenesis of patients with IgG plus C3d DAT positivity was still an obscure.

Abstract
The physiology of the immune system involves morphologic and functional changes occurring along ageing, with a decrease in immune response and an increase in autoimmune phenomena, even in the absence of overt disese. Autoimmune cytopenias, namely autoimmune hemolytic anemia (AIHA), chronic idiopathic neutropenia (CIN) and aplastic anemia (AA), show different epidemiologic predilection, but are increasingly diagnosed in the elderly, where complications and comorbidities are more frequent. A systematic review of recent literature, shows that comorbidities as well as underlying deficiencies, medications, neoplasms, and, pathophysiologic chronic organ failures, frequently challenge the differential diagnosis in this setting and should always be evaluated and excluded. Complications, particularly infections and thrombosis for AIHA, and bleeding for AA, should be monitored and promptly treated. Treatment choice should be carefully weighed on the individual general condition and comorbidities, granted that intense primary care and support (including evidence-based transfusion policies) are provided. Finally, bone marrow histology is highly advisable in the elderly, both at diagnosis to detect underlying conditions, and along the follow-up to monitor possible bone marrow failure or neoplastic evolution.

Abstract
RATIONALE Relapsing polychondritis (RP) is a rare autoimmune-related disease and may be associated with other autoimmune diseases. PATIENT CONCERNS Here we reported a case of RP patients with mixed-type AIHA. The patient was diagnosed with RP in March 2008 which was treated and the patient was in stable condition. Laboratory data revealed progressive decrease in hemoglobin during her hospitalization due to pulmonary infection in 2016. Positive Coombs' test and moderate titer of anti-cold agglutinin was detected. DIAGNOSIS Mixed-type AIHA was diagnosed as a comorbidity in this case given the circumstance that her RP was stable and low-dose oral corticosteroids was enough to maintain remission. INTERVENTIONS The patient was treated with intravenous immunoglobulin and steroids. OUTCOMES The patient's body temperature dropped and hemoglobin levels rose in 2 weeks. LESSONS Reports of RP patients with autoimmune hemolytic anemia (AIHA) are extremely rare and cases with the mixed-type AIHA has not been reported. Here we describe a case of RP with mixed-type AIHA which was considered as a comorbidity rather than a complication.

Abstract
Severe anemia can cause multilayered retinal hemorrhages. A 65-year-old woman noted "red spheres" in the central vision of both eyes during a hospital admission for autoimmune hemolytic anemia. Examination revealed extensive multilayered retinal hemorrhages, including bilateral foveal preretinal hemorrhage. Spectral-domain optical coherence tomography localized the preretinal blood to the sub-internal limiting membrane (ILM) space. Various options are available for management of such hemorrhage, including observation for spontaneous resolution, YAG laser membranotomy, or pars plana vitrectomy with ILM peeling. In the authors' patient, the size of the sub-ILM hemorrhage spontaneously improved during the course of 1 month, with both subjective and objective visual improvement.

Abstract
Background Autoimmune hemolytic anemia (AIHA) is characterized by an autoimmune-mediated destruction of red blood cells. Warm AIHA (wAIHA) represents 60% of AIHA cases and is associated with the positive detection of IgG and C3d in the direct antiglobulin test (DAT). This study aimed to assess the clinical and laboratorial differences between primary and secondary wAIHA patients from a referral center in Mexico City. Methods All patients diagnosed with wAIHA in our institution from January 1992 to December 2015 were included and received corticosteroids as the first-line treatment. We analyzed the response to the first-line treatment, relapse-free survival, and time to splenectomy. Results Eighty-nine patients were included. Secondary wAIHA represented 55.1% of the cases. At diagnosis, secondary wAIHA patients showed a DAT mixed pattern more frequently than primary wAIHA patients (36.7 vs. 17.5%, P<0.001). In the survival analysis, patients with secondary wAIHA had a lower time to response (18 vs. 37 days, P=0.05), median disease-free survival (28.51 vs. 50.95 weeks, P=0.018), and time to splenectomy (43.5 vs. 61 wks, P=0.029) than those with primary wAIHA. Due to economic constraints, rituximab was considered as the third-line treatment in only two patients. Conclusion Secondary wAIHA may benefit from a longer low-dose steroid maintenance period mainly due to its shorter time to relapse and time to splenectomy than primary wAIHA.
