CONTEXT: Thrombotic microangiopathy (TMA) is an uncommon and severe complication of snakebites, and is similar, in general, to hemolytic-uremic syndrome (HUS). We describe a case of TMA following envenomation by Bothrops jararaca. CASE DETAILS: A 56-y-old-woman with controlled hypertension was transferred from a primary hospital to our ER ∼7 h after being bitten by B. jararaca in the distal left leg. She developed edema extending from the bite site to the proximal thigh, associated with intense radiating local pain, local paresthesia and ecchymosis at the bite site...

BACKGROUND: In recent years, few cases of post-artemisinin delayed hemolysis have been reported. OBJECTIVE: All cases of post-artemisinin delayed hemolysis were reported from non-middle east areas. No case of post-artemisinin delayed hemolysis has yet been reported from this region. In this paper, we describe a case of post-artemisinin delayed hemolysis in an Iranian female. Also previous reports have been reviewed. METHOD: Patient's data including demographic characteristics, past medical, drug and travelling history, present illness, vital signs, laboratory data, clinical course of current illness and follow-up findings were considered...

Intravenous immunoglobulins (IVIg) are used in the treatment of different autoimmune and inflammatory diseases, such as immune thrombocytopenia and hemolytic anemia. One of the modes of action of IVIg is preventing phagocytosis of autoantibody-opsonized blood cells by saturation of the Fc-gamma receptors of macrophages in spleen and liver. IgG contains a fixed glycan, which is in most cases biantennary, at the asparagine residue at position 297 in the Fc tail. This glycan consists of a core structure of N-acetyl glucosamine (GlcNAc) and mannose groups, variably extended with core fucose, bisecting GlcNAc as well as terminal galactose and sialic acid...

Autoimmune hemolytic anemia (AIHA) is a very rare cause of anemia in a case of malaria and drug-induced AIHA is even rarer. A 50-year old patient with a history of fever for 8 days was diagnosed with a case of complicated malaria with mixed infection having initial parasite index of 45%. He showed good response on initial therapy with artesunate (parasite count reduced to <1%) but his haemoglobin (Hb) continued to drop from 12 g% to 4.9 g% over a course of 11 days. Direct coombs test was positive with reduced haptoglobin and increased lactate dehydrogenase suggesting AIHA...

BACKGROUND: Thrombotic microangiopathy (TMA) is an important complication associated with several diseases that are rare and life-threatening. TMA is common to thrombotic thrombocytopenic purpura (TTP) and hemolytic uremic syndrome (HUS). TTP is defined by a severe deficiency of ADAMTS13, and early treatment is associated with good prognosis. The diagnosis of HUS can be difficult due to the potential multiple etiologies, and the best treatment option in most cases is not well-established yet...

Hemolytic anemia is a common clinical disease with diverse pathogenesis. In recent years, the incidence of hemolytic anemia is increasing dramatically. The present clinical treatment of immunosuppressive agents or splenectomy is effective to some extent; however, the accompanied clinical adverse reactions are also significant. Traditional Chinese medicine (TCM) has beneficial therapeutic effect on hemolytic anemia, with the obvious advantages including curative effect, less adverse reactions, and low price...

BACKGROUND Thrombotic thrombocytopenic purpura is mostly characterized by symptoms and signs of hemolytic anemia, thrombocytopenia, renal impairment, fever and neurologic dysfunction. It is not always necessary to have all 5 characteristic symptoms, and presentations can vary. It can be congenital or acquired by any etiology that causes deficiency or dysfunction of ADAMST13 enzyme. CASE REPORT We present a case of a 71-year-old man who presented to our hospital initially with abdominal pain. He was diagnosed with pancreatitis, and conservative management was started with pain control and hydration...

We determined the clinical utility of the direct Coombs' test in the absence of hemolytic anemia as an indicator of disease activity and therapeutic response in systemic lupus erythematosus (SLE). SLE patients without hemolytic anemia who visited our hospital from January 2016 to November 2016 were retrospectively evaluated with a direct Coombs' test. Clinical features, including SLE disease activity index (SLEDAI), treatment and laboratory findings were analyzed. For patients with lupus nephritis, we additionally evaluated the cumulative complete renal response rate over one year after induction therapy...

Evans syndrome (ES) is a rare and chronic autoimmune disease characterized by autoimmune hemolytic anemia and immune thrombocytopenic purpura with a positive direct anti-human globulin test. It is classified as primary and secondary, with the frequency in patients with autoimmune hemolytic anemia being 37%-73%. It predominates in children, mainly due to primary immunodeficiencies or autoimmune lymphoproliferative syndrome. ES during pregnancy is associated with high fetal morbidity, including severe hemolysis and intracranial bleeding with neurological sequelae and death...

Atypical hemolytic uremic syndrome is a rare and progressive disease caused by uncontrolled alternative complement activation. Dysregulatıon of the complement activation results in thrombotic microangiopathy and multiorgan damage. A 29-yearold woman who was admitted with complaints of vomiting and headache was detected to have acute renal failure with microangiopathic hemolytic anemia (MAHA). After the diagnosis of atypical hemolytic uremic syndrome (aHUS), she was treated with plasma exchange (PE) and hemodialysis (HD)...

This study was designed to provide laboratory evidence supporting the hematopoietic effect of Beta vulgaris (beet) leaf aqueous extract in phenylhydrazine-induced anemia model in albino rats. Extraction of the leaves/stalks was done by maceration in 30% hydro-ethanol for 48 h. An intraperitoneal injection of 20 mg/kg phenylhydrazine was applied for two consecutive days to develop hemolytic anemia on the 4th day after the 1st injection in 24 of 30 male albino rats. The animals were divided into 5 groups and received the following treatments: standard (ferrous ascorbate + folic acid; 13...

We describe a previously healthy 14-year-old girl with acute onset autoimmune hemolytic anemia, associated with severe but transient lymphopenia during corticosteroid therapy, without infectious episodes during follow-up. After detailed investigations to rule out an underlying immunodeficiency, we detected a heterozygous ADA gene mutation. This was associated with slightly increased blood levels of adenosine and deoxyadenosine nucleotides and with reduced ADA activity in red blood cells, but within the normal range...

AMP-activated protein kinase is a heterotrimeric complex containing α, β, and γ subunits involved in maintaining integrity and survival of murine red blood cells (RBC). Indeed, Ampk α1-/-, Ampk b1-/- and Ampk γ1-/- mice present a hemolytic anemia and their RBC show elasticity defects in their plasma membrane. The membrane composition evolves continuously along erythropoiesis and during RBC maturation; defects due to the absence of AMPK could be initiated during erythropoiesis. Therefore, we aim to study the role of AMPK during human erythropoiesis...

The clinical features of transplant-associated thrombotic microangiopathy (TA-TMA) include microangiopathic hemolytic anemia, consumptive thrombocytopenia, and organ dysfunction caused by thrombi in microvessels. The pathogenesis of TA-TMA is based on vascular endothelial insults caused by various factors, including chemotherapy and total-body irradiation used for transplant pre-conditioning, calcineurin inhibitors, cytokines release associated with infection, and complement factors. The incidence of TA-TMA is approximately 15-30% among allogeneic transplant patients, and the mortality rate reaches 100% in severe cases with multi-organ dysfunction...

Evans syndrome is defined by bilineal autoimmune cytopenia, typically coombs positive hemolytic anemia and thrombocytopenia. Corticosteroids are the mainstay of treatment, with rituximab and/or mycophenolate mofetil often used in steroid-refractory cases. However, no treatment methodology has ever evaluated by a randomized clinical trial. We present a 15-year-old boy with Evans syndrome and common variable immunodeficiency who experienced a severe, refractory flare 16 months postsplenectomy. After failing to respond to multiple other agents, he achieved a durable response to a bortezomib-based regimen...

Atypical hemolytic uremic syndrome (aHUS), a rare variant of thrombotic microangiopathy, is characterized by microangiopathic hemolytic anemia, thrombocytopenia, and renal impairment. The condition is associated with poor clinical outcomes with high morbidity and mortality. Atypical HUS predominantly affects the kidneys but has the potential to cause multi-organ system dysfunction. This uncommon disorder is caused by a genetic abnormality in the complement alternative pathway resulting in over-activation of the complement system and formation of microvascular thrombi...

BACKGROUND: Vitamin B12 deficiency-induced thrombotic microangiopathy, known as pseudothrombotic microangiopathy, is a rare condition which resembles the clinical features of thrombotic thrombocytopenic purpura but requires a markedly different treatment. Most cases of vitamin B12 deficiency have only mild hematological findings, but in approximately 10% of patients life-threatening conditions have been reported. CASE PRESENTATION: We report a case of a 46-year-old Moroccan man presenting with severe hemolytic anemia, thrombocytopenia, and renal failure in absence of macrocytosis, thus mimicking a genuine thrombotic thrombocytopenic purpura...
