Auto immune haemolytic anaemia

A 7-month-old Myanmar boy was admitted with a 3-day history of fever. He was markedly pale and his temperature was 38·2°C. Peripheral blood smear demonstrated Plasmodium vivax infection with spherocytosis and auto-agglutination of red blood cells. Haematocrit was 16% and reticulocyte count 14·9%. Direct and indirect antiglobulin tests were positive. Antibody analysis was positive for auto-antigen I. P. vivax malaria with auto-immune haemolytic anaemia (AIHA) was diagnosed. He was treated with chloroquine and primaquine for the P...

BACKGROUND: Haematological disorders, in particular sickle cell disease (SCD) and thalassaemia, are relatively common in Oman. We report our experience of splenectomy for haematological disorders and review the literature on splenectomy role in their management. OBJECTIVES: To review our experience in the management of 150 patients with haematological disorders undergoing splenectomy with emphasis on indications and outcome. To compare our experience with those reported from outside this region...

OBJECTIVES: For better characterizing the effect of anti-CD20 therapy, we analysed the use of rituximab in Belgian patients experiencing auto-immune haemolytic anaemia (AIHA) and immune thrombocytopenic purpura (ITP). DESIGN: We performed a retrospective multicentric analysis of patients with AIHA and ITP treated with rituximab in Belgium. SETTING: Haematological departments were invited to fill in a questionnaire about patient and disease characteristics...

Parvovirus B19 infection has been associated with a variety of rheumatic manifestations/diseases, mainly rheumatoid arthritis, vasculitis and systemic lupus erythematosus (SLE). B19 infection may simulate both clinical and laboratory features of SLE, presenting either as a potential first time diagnosis of SLE or as an exacerbation of previously established disease. The similarities in both clinical and serological features of parvovirus infection and SLE at presentation may hinder the differential diagnosis between these two conditions...

The authors report a peculiar form of Hodgkin's disease that is associated with Epstein-Barr virus infection. A 16-year-old patient was admitted for an autoimmune haemolytic anaemia associated with IgG auto-immune antibodies, linked to general clinical complications, cervical adenopathies and splenomegalia. The patient underwent hemicavectomy that was not histologically investigated. The ganglionar exeresis helped to establish the histological diagnosis of Hodgkin's disease, classic form with nodular sclerosis...

INTRODUCTION: Confirmation of autoimmune hemolytic anaemia usually relies on the detection of erythrocyte membrane-bound autoantibodies using a direct antiglobulin test. In the rare case of IgA autoantibodies-mediated autoimmune hemolytic anemia, the direct antiglobulin test can be negative, because routinely used polyspecific direct antiglobulin test reagents contain only anti-IgG and anticomplement antibodies. EXEGESIS: We report the case of a 41-year-old woman presenting a severe autoimmune hemolytic anaemia caused by the presence of warm autoantibodies of IgA type that revealed a chronic hepatitis C virus infection...

Immune anaemias (IA) [auto-immune haemolytic anaemia (AIHA) and pure red cell aplasia (PRCA)] are complications of chronic lymphocytic leukaemia (CLL). Fludarabine has been associated with AIHA, whereas both rituximab and cyclophosphamide have been used to treat this condition. Combining these agents with fludarabine may reduce the likelihood of AIHA. We report on the incidence, outcome and pretreatment predictors of IA in 300 patients treated with fludarabine, cyclophosphamide and rituximab (FCR). Nineteen patients (6...

Rituximab use in severe auto-immune diseases has recently increased. Scattered reports of opportunistic infections were the only reported serious side effects related to rituximab in pediatric patients .Here, we report transient severe acute thrombocytopenia and neutropenia respectively a few days after rituximab infusion in two children with autoimmune haemolytic anaemia. In both cases, cytopenia was reversible in a few days. The occurrence of cytopenias shortly after an infusion and their rapid reversibility suggest that these hematological side-effects were attributable to a direct toxicity of rituximab...

UNLABELLED: The association of myelodysplastic syndromes (MDS) with auto-immune diseases and humoral disorders have already been reported. In this prospective study we tried to estimate type and the frequency of immunological associated diseases among patients affected by MDS. PATIENTS-METHODS: In this prospective study, auto-immune disease and humoral immunity disorders were systematically searched during MDS and conversely MDS searched during cytopenia. All MDS secondary to chemotherapy and the children's MDS were excluded...

UNLABELLED: Treatment of auto-immune cytopenia refractory to front line therapy with intravenous immunoglobulins and steroids is a matter of concern. We assessed the efficacy and safety of mycophenolate mofetil in a prospective open preliminary study. STUDY DESIGN: Adult patients with steroid refractory auto-immune cytopenias were included. Mycophenolate mofetil (MMF) was added to treatment given at the time of inclusion, and efficacy was evaluated in term of improvement of platelet/haemoglobin levels and in term of reduction of previously given drugs, if any...

In face of numerous benefits induced by therapy based on interferon (IFN) associated with ribavirin for the treatment of chronic hepatitis C, there is an increasing concern regarding its tolerance, which can, in some cases, reduce the quality of life as well as compliance of patients. Among the less common side effects, there are the autoimmune ones which can be globally divided into appearance or increase in titres of auto-antibodies and/or manifestation of overt autoimmune pathologies. Whereas the former may concern more than 50% of treated subjects, the latter is reported in only 1-2% of patients under therapy...

A 5-year-old Poodle-cross was initially presented for exercise intolerance and difficulty in chewing and yawning. Some months later it acutely developed lethargy referable to complete heart block. Further investigations before and after permanent pacemaker implantation demonstrated Coombs-positive immune-mediated haemolytic anaemia, presumptive masticatory myositis and hypoadrenocorticism, suggesting the possibility of multisystem auto-immune disease. A diagnosis of systemic lupus erythematosus (SLE) was made based on these findings and a positive anti-nuclear antibody titre...

The association between ulcerative colitis and auto-immune haemolytic anaemia is well described. However, only two cases of auto-immune haemolytic anaemia occurring in association with Crohn's disease have been described in the literature. We report on a third case and discuss the importance of diagnosis and the therapeutic implications of this association.
