BACKGROUND: Single nucleotide polymorphisms (SNPs) at the ITPA gene are associated with hemolytic anemia in chronic hepatitis C patients treated with peginterferon-ribavirin (RBV). Information in patients treated with interferon-free, direct-acting antivirals (DAA) is scarce. METHODS: Median hemoglobin (Hb) levels were compared at baseline and at week 4, when ribavirin concentration achieves steady state, in all consecutive chronic hepatitis C patients treated with oral DAA plus RBV at our clinic...

Atypical haemolytic uraemic syndrome (aHUS) is a rare but life-threatening complement system-related disorder, characterized by renal failure, non-immune haemolytic anaemia and thrombo-cytopenia. We report on a young woman who developed a pancreatitis-induced aHUS following a routine procedure of endoscopic retrograde cholangiopancreatography. The patient was successively treated by 2 plasma exchanges with fresh frozen plasma and eculizumab, a monoclonal antibody designed to block terminal complement activation...

Haemoglobinopathies are hereditary conditions in which the fundamental lesion affects the synthesis rate or the structure of the globin in normal hemoglobin. The synthesis of the polypeptide chains in globin is genetically coded. Clinically, haemoglobinopathies manifest most commonly in the form of hemolytic anemia and, more rarely, cyanosis and polyglobulia. They differ from "acquired haemoglobinopathies", such as methemoglobinemia, in which hemoglobin is usually compromised due to the action of toxic substances...

Background: Autoimmune haemolytic anaemia (AIHA), caused primarily by pregnancy, is poorly described in the literature. There is especially little information on coping with cases that are not responsive to glucocorticoid treatment, monitoring a fetal condition, and identifying fetal haemolytic anaemia as early as possible. Case: A case of pregnancy-induced autoimmune haemolytic anaemia is reported with major problems in differential diagnosis, treatment and the risks posed to both the mother and the fetus...

BACKGROUND: Primaquine is used to prevent Plasmodium vivax relapse; however, it is not implemented in many malaria-endemic countries, including Cambodia, for fear of precipitating primaquine-induced acute haemolytic anaemia in patients with glucose-6-phosphate dehydrogenase deficiency (G6PDd). Reluctance to use primaquine is reinforced by a lack of quality safety data. This study was conducted to assess the tolerability of a primaquine regimen in Cambodian severely deficient G6PD variants to ascertain whether a weekly primaquine could be given without testing for G6PDd...

To quantify cardiorespiratory response to experimental anaemia in rainbow trout Oncorhynchus mykiss, a 24 h phenylhydrazine treatment was used to reduce haematocrit to almost one third of its initial value over 4-5 days. In response, relative blood velocity in the ventral aorta (an index of cardiac output) progressively increased to more than double to its normocythaemic value and there was no significant change in routine oxygen uptake. Thus, the primary compensatory response to anaemia was an increase in cardiac output...

Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disease, characterized by microangiopathic hemolytic anaemia and thrombocytopenia, resulting in neurologic and/or renal abnormalities. We report a 49-year-old patient with a history of thrombotic events, renal failure, and thrombocytopenia. Blood analysis demonstrated no ADAMTS13 activity in the absence of antibodies against ADAMTS13. The complete ADAMTS13 gene was sequenced, and two mutations were identified: one mutation on exon 24 (Arg1060Asp), which had previously been described, and a mutation on exon 27 (Met1260IlefsX34), which has not been reported...

BACKGROUND: Autoimmune haemolytic anaemia (AIHA) is a rare complication following kidney transplantation and usually occurs early in its course. It is characterised by autoantibodies or alloantibodies directed against red blood cells (RBCs). CASE PRESENTATION: We describe a 44 year old woman who presented 5 years after kidney transplantation with profound transfusion dependent warm AIHA. Investigations confirmed an IgG autoantibody against RBCs and high titre Epstein-Barr virus (EBV) viraemia...

OBJECTIVES: The measurement of serum cardiac troponin I concentrations in dogs with a range of non-primary cardiac illnesses suggests that cardiac myocyte damage is commonplace. Dogs with primary immune-mediated haemolytic anaemia have increased serum cardiac troponin I concentrations at the time of diagnosis. However, it is unclear whether biochemical evidence of cardiac myocyte damage improves following successful treatment of anaemia. METHODS: A haematology profile was performed and serum cardiac troponin I concentrations were measured in 19 dogs with primary immune-mediated haemolytic anaemia before and after treatment...

BACKGROUND: Severe falciparum malaria may be complicated by haemolysis after parasite clearance, however the mechanisms remain unclear. Recent reports describe a pattern of delayed onset haemolysis among non-immune travellers with hyperparasitaemia treated with intravenous artesunate, termed post-artesunate delayed haemolysis (PADH). The occurrence and clinical impact of PADH following severe malaria infections in areas of unstable transmission are unknown. CASE: A 45-year-old Bangladeshi male was initially admitted to a local hospital with severe falciparum malaria complicated by hyperparasitaemia and treated with intravenous artesunate...

Many acute and chronic anaemias, including haemolysis, sepsis and genetic bone marrow failure diseases such as Diamond-Blackfan anaemia, are not treatable with erythropoietin (Epo), because the colony-forming unit erythroid progenitors (CFU-Es) that respond to Epo are either too few in number or are not sensitive enough to Epo to maintain sufficient red blood cell production. Treatment of these anaemias requires a drug that acts at an earlier stage of red cell formation and enhances the formation of Epo-sensitive CFU-E progenitors...

The virological diagnosis of Parvovirus B19 (PvB19) infection is currently based on sero-diagnosis, molecular methods or both, yet without clear recommendations. We retrospectively identified patients with polymerase chain reaction-positive PvB19 and/or positive serological assay between 2007 and 2013. Eighty-two adults with at least one diagnostic criterion of recent PvB19 infection (IgM antibodies, viral DNA in blood and/or in marrow) were included and classified into three homogeneous groups: 30 patients had no underlying predisposing condition, 25 a hereditary haemolytic anaemia, 27 an underlying immunodeficiency...

Wilson's disease can have different manifestations like jaundice, cirrhosis of liver, extrapyramidal symptoms and dementia. Haemolytic anaemia may occur but it is commonly associated with florid manifestation of liver disease. Sometimes, liver cell necrosis can release huge free copper ions in blood, giving rise to oxidant damage to erythrocytes. Oxidative damage to cell membrane, haemoglobin and erythrocyte metabolism causes haemolytic crisis. In some cases, liver involvement is subclinical, but nonetheless, free copper is released from necrosed hepatocytes and causes oxidative damage to erythrocytes...
