BACKGROUND: In severe malaria, intravenous artesunate may cause delayed haemolytic anaemia but there has been little evaluation of the propensity of oral artemisinin-based combination treatments (ACTs) to cause late-appearing anaemia. METHODS: The frequency of anaemia (haematocrit <30%), and temporal changes in haematocrit were evaluated in 1,191 malarious children following ACTs. "Haematocrit conservation" was evaluated by using the fall in haematocrit/1,000 asexual parasites cleared from the peripheral blood (FIH/1,000 asexual parasites cpb), and the ratio of the average haematocrit (on the first 3 days of starting treatment):total parasitaemia cleared...

We present the case of a 21-month-old girl with two rare and life-threatening conditions, atypical haemolytic uraemic syndrome (aHUS) and haemophagocytic lymphohistiocytosis (HLH), triggered by a cytomegalovirus (CMV) infection. Soon after admission, the girl became anuric and required continuous venovenous haemodiafiltration.Initial treatments included methylprednisolone, fibrinogen and plasma infusion (for HLH), plasmapheresis (for thrombotic microangiopathy), immunoglobulins (for inflammation), ganciclovir (for CMV infection) and the antibiotic cefotaxime...

Childhood autoimmune haemolytic anaemia (AIHA) requires second-line immunosuppressive therapy in 30-50% of cases. It appears that rituximab is indicated in such circumstances. This prospective national study reports the practice, efficacy and tolerance of rituximab in children with isolated AIHA and AIHA in the setting of Evans syndrome (ES). Sixty-one children were given rituximab between 2000 and 2014. The median interval from diagnosis to rituximab was 9·9 [interquartile range (IQR) 1·6-28·5] months. Forty-six patients responded (75%) and the 6-year relapse-free survival (RFS) was 48%...

BACKGROUND: Atypical haemolytic uraemic syndrome (aHUS) presents similarly to thrombotic thrombocytopenic purpura (TTP), and other causes or conditions with thrombotic microangiopathy (TMA) such as DIC or sepsis. Similarity in clinical presentation may hinder diagnosis and optimal treatment selection in the urgent setting in the ICU. However, there is currently no consensus on the diagnosis or treatment of aHUS for ICU specialists. This review aims to summarise available data on the diagnosis and treatment strategies of aHUS in the ICU in order to enhance the understanding of aHUS diagnosis and outcomes in patients managed in the ICU...

The purpose of study was to conjugate and evaluate methotrexate with C60-fullerenes and multi-walled carbon nanotubes (MWCNTs) for better drug delivery to cancer cells, and also to compare these two systems. C60-fullerenes and MWCNTs were functionalized by 1,3-dipolar cycloaddition using glycine and paraformaldehyde. Methotrexate (MTX) was esterified and conjugated to the functionalized carbon-based carriers. The conjugates were characterized for micromeritics and drug conjugation. The systems were evaluated for drug release in various pH, MTT cytotoxicity assay, protein binding, cellular uptake, haemolytic profile and pharmacokinetics...

Haemolytic disease of the foetus and newborn (HDFN) is caused by maternal red blood cells (RBC) alloimmunisation resulted from incompatibility of maternal and foetal RBCs. However, only a few HDFN attributed to anti-M were reported, varying from asymptomatic to severe anaemia with hydrops foetalis and even intrauterine death. A case of severe HDFN due to anti-M alloantibody from an alloimmunized grandmultiparous Malay woman with recurrent pregnancy loss is reported here. The newborn was delivered with severe and prolonged anaemia which required frequent RBC transfusions, intensive phototherapy and intravenous immunoglobulin administration...

INTRODUCTION: Some studies suggest that thrombotic thrombocytopenic purpura (TTP) occurs more often in African Americans. However there is low evidence for this in the literature. The aim of our study was to describe the clinical and biological characteristics of TTP in the Afro-Caribbean population of Martinique. METHODS: We retrospectively analysed all patients with TTP diagnosed at the Fort-de-France hospital between 2008, January 1st and 2015, December 31st...

Enteric infectious disease in weaner piglets, including postweaning diarrhoea (PWD), are usually treated and/or prevented with antibiotics and/or zinc oxide in the piglet feed. However extensive use of antibiotics and zinc oxide in intensive animal production is unwanted as it may promote microbial antibiotic resistance and pose environmental problems. Recently, in an experimental model of PWD, we observed that oral administration of purified porcine immunoglobulin G (ppIgG) from pooled natural pig plasma could reduce enteric infection...

We sought to determine the prevalence of dog erythrocyte antigen (DEA) 1, 4 and 7 and naturally occurring anti-DEA7 antibodies in Italian Corso dogs. In addition, we correlated DEAs with different epidemiologic variables, compared the prevalence of DEAs against other canine populations and assessed the risk of sensitisation and transfusion reactions (TRs) following unmatched transfusion. Blood samples from 100 Corso dogs were evaluated for DEA 1, 4, 7 and naturally occurring anti-DEA 7 antibodies. Seventy-one percent of samples were DEA 1-negative, 100% tested DEA 4-positive, and 95% tested DEA 7-negative...

Recently, interesting work was published by Farrar et al. [1] showing the interaction of fucosylated glycoproteins on stressed tubular epithelial cells with collectin-11 leading to complement activation via the lectin route of complement. This elegant work stimulated us to evaluate the dark side (bittersweet taste) of tubulo-interstitial glycans in kidney tissue damage. As will be discussed, glycans not only initiate tubular complement activation but also orchestrate tubulo-interstitial leucocyte recruitment and growth factor responses...

Background: Artesunate (AS) is the WHO first-line treatment of severe malaria in endemic countries, in adults and children. However, despite solid evidence that AS is safe and more effective than quinine in endemic areas, its deployment in non-endemic areas has been slow, due in part to the absence of a full good manufacturing practice (GMP) qualification (although prequalification has been granted in 2010). Prospective comparative trials were not conducted in travellers, but several retrospective studies and case reports are providing insights into the efficacy and safety of AS in imported severe malaria...

Shiga toxin-producing Escherichia coli (STEC) may cause haemolytic uraemic syndrome (HUS). Age ≤5 years and presence of stx2a and eae are risk factors for the development of HUS. In this study, we investigated STEC isolates for the presence of adhesins, toxins and molecular risk assessment (MRA) factors to identify virulence genes associated with HUS development. We included non-duplicate isolates from all STEC infections (n = 340, HUS = 32) reported to the Norwegian National Reference Laboratory (NRL) for Enteropathogenic Bacteria from 1992 to 2013...

Background: Kidney transplantation in patients with atypical haemolytic uraemic syndrome (aHUS) is frequently complicated by recurrence of aHUS, often resulting in graft loss. Eculizumab prophylaxis prevents recurrence, improving graft survival. An alternative treatment strategy has been proposed where eculizumab is administered upon recurrence. We combined available evidence and performed a cost-effectiveness analysis of these competing strategies. Methods: A cost-effectiveness analysis using a decision analytical approach with Markov chain analyses was used to compare alternatives for aHUS patients with end-stage renal disease (ESRD): (i) dialysis treatment, (ii) kidney transplantation, (iii) kidney transplantation with eculizumab therapy upon recurrence of aHUS, (iv) kidney transplantation with eculizumab induction consisting of 12 months of prophylaxis and (v) kidney transplantation with lifelong eculizumab prophylaxis...

Haemolytic-uraemic syndrome (HUS) is a rare disease mainly affecting children that develops as a complication of shiga toxin-producing Escherichia coli (STEC) infection. It is characterised by acute kidney injury, platelet consumption and mechanical destruction of red blood cells (haemolysis). In order to test the working hypothesis that the spread of the infection is influenced by specific climatic conditions, we analysed all of the identified cases of infection occurring between June 2010 and December 2013 in four provinces of Lombardy, Italy (Milano, Monza Brianza, Varese and Brescia), in which a STEC surveillance system has been developed as part of a preventive programme...

An 83-year-old man with severe symptomatic aortic valve stenosis underwent transcatheter aortic valve implantation (TAVI) using a 29 mm SAPIEN XT valve. He was haemodynamically stable, but developed haemolytic anaemia. Transthoracic echocardiography conducted 7 days after TAVI revealed an abnormal continuous flow from the right sinus of Valsalva adjacent to the implanted valve to the right ventricle. The amount of shunt flow was considered small and the patient was managed with diuretics successfully. He was discharged from the hospital 35 days after TAVI...
