BACKGROUND: Internal tandem duplication mutations in FLT3 are common in acute myeloid leukaemia and are associated with rapid relapse and short overall survival. The clinical benefit of FLT3 inhibitors in patients with acute myeloid leukaemia has been limited by rapid generation of resistance mutations, particularly in codon Asp835 (D835). We aimed to assess the highly selective oral FLT3 inhibitor gilteritinib in patients with relapsed or refractory acute myeloid leukaemia. METHODS: In this phase 1-2 trial, we enrolled patients aged 18 years or older with acute myeloid leukaemia who either were refractory to induction therapy or had relapsed after achieving remission with previous treatment...

AIMS: To explore whether a quantitative approach to identifying hospitalized patients with diabetes at risk of hypoglycaemia would be feasible through incorporation of routine biochemical, haematological and prescription data. METHODS: A retrospective cross-sectional analysis of all diabetic admissions (n=9584) from 1 January 2014 to 31 December 2014 was performed. Hypoglycaemia was defined as a blood glucose level of <4 mmol/l. The prediction model was constructed using multivariable logistic regression, populated by clinically important variables and routine laboratory data...

This is an article reviewing the management of pregnant women with factor XI (FXI) deficiency. Retrospective review of the electronic records of 67 pregnancies in 25 women with FXI deficiency over a ten-year period was undertaken. All women received care at St Mary's Tertiary Referral Obstetric/Haematology Clinic for some or all of their pregnancies. Outcome measures included antenatal complications, mode of delivery, anaesthesia provided and postpartum haemorrhage (PPH) and management required. A positive bleeding history was identified in 50% of women prior to pregnancy...

CD25 (also termed IL2RA) forms one component of the high-affinity heterotrimeric interleukin 2 (IL2) receptor on activated T cells. Its affinity for IL2 and cellular function are tightly regulated and vary in different cell types. The high frequency of CD25 on the surface of many different haematological tumour cells is now well established and, apart from its prognostic significance, CD25 may be present on leukaemic stem cells and enable oncogenic signalling pathways in leukaemic cells. Additionally, high CD25 expression in activated circulating immune cells and Tregs is a factor that has already been exploited by IL2 immunotherapies for treatment of tumours and autoimmune disease...

BACKGROUND: Leptospirosis is a re-emerging bacterial zoonosis caused by spirochetes of the genus Leptospira. Severe disease has been reported in dogs in Europe despite vaccination with bivalent Leptospira vaccines. Recently, a tetravalent canine Leptospira vaccine (Nobivac® L4) was licenced in Europe. The goal of this study was to investigate clinical signs, microscopic agglutination test (MAT) titres, haematology, blood biochemistry, cardiac (c) Troponin I levels and echocardiography before and after vaccination with this tetravalent vaccine...

Broilers commonly suffer from necrotic enteritis (NE). Other gastrointestinal infectious diseases affect poultry, including nematode infections which are considered a re-emerging disease in barn and free-range systems. The aim of this study was to characterise the immune response of broilers after artificial infection with NE and contrast these with responses to the nematode Ascaridia galli and determine whether immune parameters measured during the course of infection can be used to distinguish infected from uninfected birds...

BACKGROUND: Weekend hospital admission is associated with increased mortality, but the contributions of varying illness severity and admission time to this weekend effect remain unexplored. METHODS: We analysed unselected emergency admissions to four Oxford University National Health Service hospitals in the UK from Jan 1, 2006, to Dec 31, 2014. The primary outcome was death within 30 days of admission (in or out of hospital), analysed using Cox models measuring time from admission...

A differential diagnosis of testicular torsion and epididymitis has serious importance for testicular health. In emergency conditions, if testicular torsion goes unnoticed and epididymo-orchitis is diagnosed, organ loss may occur. This study aimed to evaluate the usefulness of haematologic parameters for the diagnosis of both testicular torsion and epididymo-orchitis and for differential diagnosis of these two diseases. Patients were divided into three groups as those undergoing surgery for testicular torsion, those receiving medical treatment for epididymitis and a healthy control group...

BACKGROUND: Pancreatic cancer statistics are dismal, with a 5-year survival of less than 10%, and more than 50% of patients presenting with metastatic disease. Metabolic reprogramming is an emerging hallmark of pancreatic adenocarcinoma. CPI-613 is a novel anticancer agent that selectively targets the altered form of mitochondrial energy metabolism in tumour cells, causing changes in mitochondrial enzyme activities and redox status that lead to apoptosis, necrosis, and autophagy of tumour cells...

BACKGROUND: It has long been established that cardiotoxicity occurs as a result of exposure to certain chemotherapeutics, particularly anthracyclines. Historically, clinicians equate cardiotoxicity with a poor prognosis, in a small percentage of patients and deem long-term surveillance as optional. Emerging evidence suggests that anthracycline cardiotoxicity (ACT) is a life-long risk with an incidence approaching 20%. METHODS: Participants were identified via the Haematology-Oncology (HO) database at the Royal Children's Hospital, Melbourne...

Recent decades have seen the emergence of new problems in haematology training, relating particularly to an expanding curriculum, less time available for training, staff shortages and the increasing separation of clinical haematology from its laboratory base. We have sought to identify the problems and propose possible solutions.

REVIEW
Martha Grogan, Angela Dispenzieri, Morie A Gertz
Amyloid light chain (AL) amyloidosis is a systemic disease characterised by the aggregation of misfolded immunoglobulin light chain (LC), predominantly in the heart and kidneys, causing organ failure. If untreated, the median survival of patients with cardiac AL amyloidosis is 6 months from the onset of heart failure. Protracted time to establish a diagnosis, often lasting >1 year, is a frequent factor in poor treatment outcomes. Cardiologists, to whom patients are often referred, frequently miss the opportunity to diagnose cardiac AL amyloidosis...

Many sport competitions, typically involving the completion of single- (e.g. track-and-field or track cycling events) and multiple-sprint exercises (e.g. team and racquet sports, cycling races), are staged at terrestrial altitudes ranging from 1000 to 2500 m. Our aim was to comprehensively review the current knowledge on the responses to either acute or chronic altitude exposure relevant to single and multiple sprints. Performance of a single sprint is generally not negatively affected by acute exposure to simulated altitude (i...

Technological advances in laboratory automation are now well understood and applied as they considerably improved the speed and robustness of haematological laboratory data, in the companion fields of blood analyzers and flow cytometry. Still rather confidential is the field of microfluidics, mostly confined so far to academic settings and research laboratories. The literature in the field of microfluidics is growing and applications in hematology range from cell counting to flow cytometry, cell sorting, or ex vivo testing...

Diabetes mellitus encompasses a group of highly prevalent carbohydrate metabolic disorders with an increasing incidence. Some subtypes are thought to be associated with other immune-mediated diseases. Acquired haemophilia on the other hand is a quite rare autoimmune disease that is thought to be secondary to the emergence of inhibiting anticoagulation factor VIII antibodies (inhibitors) in patients with previously normal haemostatic function. More recently, numerous different diseases have been associated with acquired haemophilia namely immune-mediated diseases, drugs and solid and haematologic neoplasms...

REVIEW

Pancreatic ductal adenocarcinoma is a devastating disease with a poor prognosis regardless of stage. To date the mainstay of therapy for advanced disease has been chemotherapy with little incremental improvements in outcome. Despite extensive research investigating new treatment options the current practices continue to utilise fluorouracil or gemcitabine containing combinations. The need for novel therapeutic approaches is mandated by the ongoing poor survival rates associated with this disease. One such approach may include manipulation of ribosome biogenesis and the nucleolar stress response, which has recently been applied to haematological malignancies such as lymphoma and prostate cancer with promising results...

BACKGROUND: Non-Hodgkin lymphoma (NHL) is often diagnosed after emergency presentation, a route associated with poor survival and an indicator of diagnostic delay. Accounting for around half of all NHLs, diffuse large B-cell lymphoma (DLBCL) is of particular interest since although it is potentially curable with standardised chemotherapy it can be challenging to identify at an early stage in the primary care setting. PATIENTS AND METHODS: Set within a socio-demographically representative United Kingdom population of around 4 million people, data are from an established patient cohort...

The primary aim of this prospective study is to develop and validate a new prognostic model for predicting the risk of mortality in Emergency Department (ED) patients. The study involved 1765 patients in the development cohort and 1728 in the validation cohort. The main outcome was mortality up to 30 days after admission. Potential risk factors included clinical characteristics, vital signs, and routine haematological and biochemistry tests. The Bayesian Model Averaging method within the Cox's regression model was used to identify independent risk factors for mortality...

Yvette N Lamb, Lesley J Scott
Intravenous liposomal irinotecan injection (Onivyde(®)) is approved for use in combination with 5-fluorouracil and leucovorin (5-FU/LV) in patients with metastatic pancreatic adenocarcinoma that has progressed following gemcitabine-based therapy. Liposomal irinotecan is a liposome-encapsulated formulation of the topoisomerase-1 inhibitor irinotecan, developed to overcome the pharmacological and clinical limitations of non-liposomal irinotecan. In the pivotal multinational, phase III NAPOLI-1 trial in patients with metastatic pancreatic adenocarcinoma that had progressed following gemcitabine-based therapy, liposomal irinotecan in combination with 5-FU/LV significantly prolonged median overall survival (OS; primary endpoint) and median progression-free survival (PFS) at the time of the primary analysis (after 313 events) and final analysis (after 382 events) compared with 5-FU/LV control therapy...

There is a need to find/discover novel leads to treat complex and/or multi-factorial-pathogenic disease(s) like Nonsteroidal anti-inflammatory drugs (NSAID)-induced gastroenteropathy or gastrointestinal (GI) toxicity as it has emerged as an important medical and socioeconomic problem. There is no approved therapeutic strategy to prevent NSAID-induced enteropathic damage and highly effective gastro-protective drugs such as ranitidine hydrochloride (RAN) exacerbate it. In this purview, the multi target drug discovery approach (MTDD), combination approach and hit to lead strategies based on the foundation of ethnopharmacology and/or reverse pharmacology holds strong potential...
