Hepatitis C in haematological patients.  


There is no consensus guideline concerning the management of chronic hepatitis C patients during chemotherapy, and immunosuppression. However, there are some suggestions in literature that hepatitis C viral load increases during chemotherapy and there is a risk of rebound immunity against hepatitis C after discontinuation of immunosuppression with a consequent liver injury. A close monitoring of liver function of these patients is prudent during treatment of haematological malignancy. Antiviral treatment is deferred after the completion of chemotherapy and recovery of patients' immunity to minimize the toxicity of treatment. A combination of pegylated interferon and ribavirin is the standard therapy in hepatitis C infected haematological patients. PMID:21188204

Intracranial haemorrhage in idiopathic thrombocytopenic purpura. Paediatric Haematology Forum of the British Society for Haematology  

Microsoft Academic Search

A UK survey was carried out to discover the frequency, circumstances, and outcome of intracranial haemorrhage (ICH) complicating idiopathic thrombocytopenic purpura (ITP) of childhood. A questionnaire was circulated through the membership of the UK Paediatric Haematology Forum, and thence to local paediatricians and haematologists. It sought information on any child with ITP who had had an ICH during the 20

A survey of Australian haematology reference intervals.  


This study was designed to create a snapshot of Australian haematology reference intervals (RIs) in use, in particular red cell parameters. We present an analysis of survey results conducted across Australian laboratories between November 2012 and January 2013.All Australian laboratories enrolled in the Royal College of Pathologists of Australasia Quality Assurance Program (RCPA QAP) were invited to participate in the December 2012 Survey Monkey survey, with a response from 85 laboratories (17%) received. The scope included laboratory demographics (location, size/throughput, and network), RIs in use for the full blood count and selected derived parameters, their frequency of revision, source and statistical approach for derivation. Further questions related to uncertainty of measurement, pregnancy values, paediatric/adult cut-off, haematology profiles reported and the use of extended parameters.There is more consistency with some upper and lower limits than others, and wide ranges for reported uncertainty of measurement (UM). There is no apparent consistency with RIs used for particular instruments and technologies. When laboratories change their RIs, most obtain them from a text book, paper or another laboratory and have difficulty in determining the source. If they do determine their own, most don't have a standard operating procedure and calculations are not consistent in terms of sample size and statistical methods used.We have presented evidence of the wide variations in RIs used in Australian laboratories and that arguably these do not differ significantly from each other. The paediatric age cut-off requires standardisation. PMID:25158822

Comparison of automated haematology analysers for detection of apoptotic lymphocytes.  


Automated haematology analysers can rapidly provide accurate blood cell counts and white blood cell differentials. In this study, we evaluated four different haematology analysers for the detection of apoptotic lymphocytes in peripheral blood: MAXM A/L Retic, H*2, Cell-Dyn 3500 and NE-8000. With the MAXM A/L Retic haematology analyser, the apoptotic lymphocyte cluster appeared below the original lymphocyte cluster on the volume/DF1, and to the right under the original lymphocyte cluster on the volume/DF2 scattergrams. With the H*2 haematology analyser, the apoptotic polymorphonuclear lymphocytes produced a higher lobularity index on the BASO channel. With the Cell-Dyn 3500 haematology analyser, the apoptotic lymphocyte cluster appeared to the right side of the original lymphocyte cluster on the 0D/10D scattergram and to the left side of the polymorphonuclear cluster on the 90D/10D scattergram. With the NE-8000 haematology analyser, the apoptotic lymphocyte cluster was not distinguishable. Thus, apoptotic lymphocytes are readily detected on scattergrams generated by selected haematology analysers. PMID:12067276

Haematological values of Nigerian goats and sheep.  


Haematological parameters were determined in healthy Nigerian breeds of goats and sheep. Most values in the Nigerian goats were similar to those reported for temperate breeds of goats although the haemoglobin concentrations and the MCHC were lower. The haematocrit, haemoglobin concentrations and red cell counts of the West African Dwarf sheep were lower while the MCV were higher than those reported for sheep in the temperate climate. RBC values decreased with age in both Nigerian goats and sheep. Although sex pregnancy appeared to have little or no influence on the erythrocytic values, pregnant ewes had higher haematocrit and haemoglobin values. The low erythrocytic values were attributed to a low but constant parasitic burden which affected the flocks studied. Total leucocyte counts were considerably higher in the Nigerian goats and sheep than those reported for temperate breeds of animals. Young goats had higher total leucocyte counts while pregnant goats had reduced leucocyte counts. The leucocytic values were not affected by age and sex. Pregnant ewes also had higher leucocyte counts than non-pregnant ewes and rams. PMID:968949

Spleen in haematological malignancies: spectrum of imaging findings  

PubMed Central

Imaging morphology and metabolic activity of splenic lesions is of paramount importance in patients with haematological malignancies; it can alter tumour staging, treatment protocols and overall prognosis. CT, MRI and positron emission tomography (PET)/CT have been shown to be powerful tools for the non-invasive assessment of splenic involvement in various haematological malignancies. Since many haematological malignancies and non-neoplastic conditions can involve the spleen and imaging manifestations can overlap, imaging and clinical findings outside of the spleen should be looked for to narrow the differential diagnosis; confirmation can be obtained by pathological findings. Radiologists should be familiar with the cross-sectional imaging patterns of haematological malignancies involving the spleen as well as non-neoplastic splenic findings common in these patients to facilitate their care and follow-up. This pictorial review provides the common and uncommon imaging appearances and complications of various haematological malignancies involving the spleen on CT, MRI and PET/CT, and common pitfalls in diagnosis.

Haematological Reference Intervals in a Multiethnic Population  

PubMed Central

Introduction Similar to other populations, full blood count reference (FBC) intervals in Malaysia are generally derived from non-Malaysian subjects. However, numerous studies have shown significant differences between and within populations supporting the need for population specific intervals. Methods Two thousand seven hundred twenty five apparently healthy adults comprising all ages, both genders and three principal races were recruited through voluntary participation. FBC was performed on two analysers, Sysmex XE-5000 and Unicel DxH 800, in addition to blood smears and haemoglobin analysis. Serum ferritin, soluble transferrin receptor and C-reactive protein assays were performed in selected subjects. All parameters of qualified subjects were tested for normality followed by determination of reference intervals, measures of central tendency and dispersion along with point estimates for each subgroup. Results Complete data was available in 2440 subjects of whom 56% (907 women and 469 men) were included in reference interval calculation. Compared to other populations there were significant differences for haemoglobin, red blood cell count, platelet count and haematocrit in Malaysians. There were differences between men and women, and between younger and older men; unlike in other populations, haemoglobin was similar in younger and older women. However ethnicity and smoking had little impact. 70% of anemia in premenopausal women, 24% in postmenopausal women and 20% of males is attributable to iron deficiency. There was excellent correlation between Sysmex XE-5000 and Unicel DxH 800. Conclusion Our data confirms the importance of population specific haematological parameters and supports the need for local guidelines rather than adoption of generalised reference intervals and cut-offs.

Zygomycosis in Immunocompromised non-Haematological Patients  

PubMed Central

Zygomycoses caused by fungi of the mucorales order (mucormycoses) are emerging fungal diseases with a high fatality rate. The most important risk factors include neutropenia or functional neutropenia, diabetic ketoacidosis, iron overload, major trauma, prolonged use of corticosteroids, illicit intravenous drug (ID) use, neonatal prematurity, malnourishment, and maybe a previous exposure to antifungal agents with no activity against zygomycetes, such as voriconazole and echinocandins. A high index of suspicion is crucial for the diagnosis, as prompt and appropriate management can considerably reduce morbidity and mortality. Suspicion index can be increased through recognition of the differential patterns of clinical presentation. In the non- haematological immunocompromised patients, mucormycosis can manifest in various clinical forms, depending on the underlying condition: mostly as rhino-orbital or rhino-cerebral in diabetes patients, pulmonary infection in patients with malignancy or solid organ transplantation, disseminated infection in iron overloaded or deferoxamine treated patients, cerebral - with no sinus involvement - in ID users, gastrointestinal in premature infants or malnourishment, and cutaneous after direct inoculation in immunocompetent individuals with trauma or burns. Treating a patient’s underlying medical condition and reducing immunosuppression are essential to therapy. Rapid correction of metabolic abnormalities is mandatory in cases such as uncontrolled diabetes, and corticosteroids or other immunosuppressive drugs should be discontinued where feasible. AmphotericinB or its newer and less toxic lipid formulations are the drugs of choice regarding antifungal chemotherapy, while extensive surgical debridement is essential to reduce infected and necrotic tissue. A high number of cases could be prevented through measures including diabetes control programmes and proper pre- and post-surgical hygiene. PMID:21625316

Iron metabolism and fungal infections in patients with haematological malignancies.  

PubMed Central

AIM--To determine whether iron metabolism influences the incidence of systemic fungal infection in patients with haematological malignancies. METHODS--The study population comprised 74 patients who had undergone myeloablative chemotherapy. Systemic fungal infections were classified as confirmed (histological confirmation or characteristic septate hyphae) or possible (antibiotic resistant fever which resolved following administration of intravenous amphotericin B, together with either typical radiographic lesions or massive oropharyngeal candidiasis). Parameters of iron metabolism included serum iron concentrations, total iron binding capacity, serum transferrin, and ferritin concentrations and transferrin saturation values. RESULTS--Patients who developed a fungal infection had substantially increased transferrin saturation values and ferritin concentrations at diagnosis together with low serum transferrin and high serum iron concentrations. This profile was present in patients with a fungal infection regardless of the underlying haematological disorder. CONCLUSION--Increased transferrin saturation values and high ferritin concentrations may be additional risk factors for the development of systemic fungal infection in patients with haematological malignancies.

Lymph nodes cytology in HIV seropositive cases with haematological alterations  

PubMed Central

Background & objectives: Lymphadenopathy and haematological alterations are the earliest manifestations with other associated opportunistic infections and malignancies. Hence, there is a need for simple investigations like fine needle aspiration cytology (FNAC) for evaluation of HIV lymphadenopathy and a haemogram to interpret the haematological alterations. This study was undertaken to analyze the cytological patterns of lymph node lesions in HIV/AIDS patients, to compare with available clinico-pathological and haematological parameters to segregate lymphadenopathy cases for further evaluation. Methods: In the present study, 129 HIV seropositive patients were included. Lymph node aspirates were stained routinely with hematoxylin and eosin and Ziehl-Neelsen (Z-N) stains. Special stains and cultures were done in selected patients. Peripheral smears were taken from all the patients and CD4 counts were recorded. Tuberculous lymphadenitis was further categorized. Acid fast bacilli (AFB) grading was done on Z-N positive smears. Each lesion was compared with CD4 counts, WHO clinical staging and haematological picture. Results: Cytological diagnosis in 129 patients included tuberculous (n=54, 41.9%), reactive lymphadenopathy (n=46, 35.6%), suppurative (n=16, 12.4%) lymphadenitis, non-Hodgkin's lymphoma (n=4, 3.1%), and Hodgkin's lymphoma, secondary deposits, other granulomatous lesions, and cryptoccocal lymphadenitis in one patient each. The predominant cytomorphological pattern in tuberculous lymphadenitis was caseous necrosis + epithelioid granuloma formation (51.85%). Grade 2+ Z-N grading was noted in 62.96 per cent of AFB positive smears. CD4 counts showed a descending pattern with progression of WHO clinical staging. Cytopenia was more common in WHO clinical stage IV disease. Interpretation & conclusions: Lymph node cytology was found to be a useful tool for segregating lymphadenopathy cases for further evaluation and for identification of opportunistic infections, neoplastic and non-neoplastic lesions. Comparison of lymph node lesions with CD4 counts, WHO clinical staging, haematological alterations and AFB grading reflects immunity, stage of disease and disease activity aiding better treatment.

Advances in Haematological Pharmacotherapy in 21st Century  

PubMed Central

Last quarter of twentieth century and the first 10 years of 21st century has seen phenomenal development in haematological pharmacotherapy. Tailor made chemotherapeutic agents, vast array of monoclonal antibodies, epigenetic modifiers, growth factors for red cells white cells and platelets, peptidomimetics as growth factors, newer thrombin inhibitors, safer plasma derived protein molecules, recombinant molecules, newer immunomodulators, enzyme replacement therapy and above all a plethora of targetted molecules targeting innumerable pathways involved in cell division, growth, proliferation and apoptosis has given immense number of clinically usable molecules in the hand of modern haematologists to treat diverse hitherto untreatable haematological disorders effectively. In addition many old molecules are finding newer uses in diverse fields, thalidomide as an antiangiogenic molecule is a prime example of this genre. Present overview has tried to capture this rapidly evolving area in a broad canvas without going into details of indications and contraindications of the use of various drugs. PMID:21629633

Financial and social impact of supporting a haematological cancer survivor  

PubMed Central

Support persons of haematological cancer survivors may be faced with unique challenges due to the course of these diseases and the treatments required. This study aimed to examine the social and financial impacts associated with their role. Eight hundred adult survivors of haematological cancer within 3 years of diagnosis were invited via an Australian state population-based cancer registry to complete a survey. Survivors were mailed two questionnaire packages, one for themselves and one for their primary support person. Non-respondents were mailed reminders via the survivor after 3 weeks. One hundred and eighty-two support persons completed the questionnaire (85% response rate). Of these, 67 (46%) support persons reported having at least one personal expense and 91 (52%) experienced at least one financial impact. Male support persons and support persons of survivors in active treatment reported experiencing more personal expenses than other support persons. Older participants reported fewer financial consequences. A greater number of social impacts were reported by those born outside Australia, those who had to relocate for treatment and support persons of survivors in active treatment. Future research should focus on practical solutions to reducing these impacts on support persons. PMID:22070745




Haemodynamic and haematologic effects of Acanthaster planci venom in dogs.  


This study was designed to examine haemodynamic and haematologic effects of the crown-of-thorns starfish venom (Acanthaster planci venom: APV) in dogs. Severe systemic hypotension, thrombocytopenia and leukopenia were induced by APV (1.0 mg protein/kg i.v.), followed by gradual return to the baseline level within 60 min. Hypotension was presumably caused by two factors: an early decrease in systemic vascular resistance and the large reduction in cardiac output due to reduced ventricular filling. Indomethacin, a cyclooxygenase inhibitor, remarkably suppressed systemic hypotension induced by APV. The peak reduction in systemic pressure was associated with concomitant rise of plasma 6-keto-PGF1 alpha, a major stable metabolite of prostacyclin. Thus, the hypotensive effect of APV may be caused primarily by prostacyclin and/or some vasodilating prostaglandins. In contrast, thrombocytopenia and leukopenia were not affected by cyclooxygenase inhibitor, 5-lipoxygenase inhibitor or platelet activating factor (PAF) receptor antagonist. When APV was administered repeatedly, tachyphylaxis was developed in haemodynamic effects, but not in haematologic effects. These findings suggest that APV-induced hypotensive effects may occur mainly through endogenous production of vasodilating prostaglandins including prostacyclin, although APV-induced thrombocytopenia and leukopenia may be caused by other mechanism(s) unrelated to arachidonate metabolites and/or PAF.

Long Non-Coding RNAs in Haematological Malignancies  

PubMed Central

Long non-coding RNAs (lncRNAs) are functional RNAs longer than 200 nucleotides in length. LncRNAs are as diverse as mRNAs and they normally share the same biosynthetic machinery based on RNA polymerase II, splicing and polyadenylation. However, lncRNAs have low coding potential. Compared to mRNAs, lncRNAs are preferentially nuclear, more tissue specific and expressed at lower levels. Most of the lncRNAs described to date modulate the expression of specific genes by guiding chromatin remodelling factors; inducing chromosomal loopings; affecting transcription, splicing, translation or mRNA stability; or serving as scaffolds for the organization of cellular structures. They can function in cis, cotranscriptionally, or in trans, acting as decoys, scaffolds or guides. These functions seem essential to allow cell differentiation and growth. In fact, many lncRNAs have been shown to exert oncogenic or tumor suppressor properties in several cancers including haematological malignancies. In this review, we summarize what is known about lncRNAs, the mechanisms for their regulation in cancer and their role in leukemogenesis, lymphomagenesis and hematopoiesis. Furthermore, we discuss the potential of lncRNAs in diagnosis, prognosis and therapy in cancer, with special attention to haematological malignancies. PMID:23887658

Haematology of wild penguins (spenisciformes) in the Falkland Islands.  


Haematological values were determined in 50 Rockhopper (Eudyptes crestatus), 19 Gentoo (Pygoscelis papua) and 12 Magellanic (Spheniscus magellanicus) penguins from various sites on the Falkland Islands. Adult Magellanic penguins had significantly lower haemoglobin (Hb) levels, packed cell volumes (PCV) and red cell counts (RBC) than adults of the other two species. Hb, PCV and RBC values were also lower in juvenile birds than in adults and lower in post-moult than in pre-moult adults. Comparison of findings in wild Rockhopper and Gentoo penguins with values obtained from captive birds showed slight but significant differences in Hb and mean cell haemoglobin concentration, and in the relative numbers of heterophils, lymphocytes, monocytes and eosinophils present.

Haematological characteristics associated with parasitism in bream, Abramis brama orientalis.  


A parasitological investigation was done on 175 specimens. Infections of A. brama orientalis were analyzed according to the age and sex. The fish also were examined for evaluation changes of haematological parameters in relation to parasitic infection. Four parasites were found, including-Caryophyllaeus laticeps and Ligula intestinalis (Cestoda), Diplostomum spathaceum (Platyhelminthes) and Trichodina sp. (Ciliophora). Among identified parasites maximum prevalence and mean intensity were related to Ligula intestinalis and Caryophyllaeus laticeps respectively. The values of prevalence and mean intensity showed significant differences among ages. Our results revealed prevalence, mean intensity and abundance had not significant difference between males and females. Parasite infection provoked reduction (P < 0.05) in haematocrit, mean cell volume and lymphocyte. On the other hand, significant increase (P < 0.05) in white blood cell (WBC), mean cell haemoglobin concentration and neutrophil in blood of infected fish was observed. Significant differences were detected for the WBC, lymphocyte and neutrophil (infected versus uninfected by Trichodina sp., Diplostomum spathaceum and Caryophyllaeus laticeps). In addition to WBC and lymphocytes, significant change was observed for the haemoglobin (Hb) (infected versus uninfected by Ligula intestinalis). PMID:25320488

Incidence and pattern of liver involvement in haematological malignancies.  


The incidence and pattern of liver involvement in 127 liver specimens (2 biopsy and 125 autopsy specimens) from cases of acute myelogenous leukaemia (25), chronic myelogenous leukaemia (7), acute lymphatic leukaemia (5), chronic lymphatic leukaemia (9), multiple myeloma (25), low-grade non-Hodgkin's lymphoma (25), high-grade non-Hodgkin's lymphoma (24) and myeloproliferative diseases (7) were investigated histologically and immunohistochemically. Liver infiltration was found frequently in chronic leukaemia and myeloproliferative diseases (80-100%), acute leukaemia (60-70%) and non-Hodgkin's lymphoma (50-60%), but was significantly less common in multiple myeloma (32%) than in any of the other diagnostic groups. Hepatomegaly was found in over 50% of cases in all the diagnostic groups, but was not always associated with infiltration. Diffuse, non-destructive infiltration was most common: in acute myelogenous leukaemia, both the portal triads and sinusoids were usually involved; in chronic myelogenous leukaemia, multiple myeloma and myeloproliferative diseases, infiltration was mainly sinusoidal; and in lymphatic leukaemia and non-Hodgkin's lymphoma the portal triads were mainly involved. Nodular infiltration was seen in multiple myeloma and non-Hodgkin's lymphoma. The primary tumours and liver infiltrates generally exhibited the same immunophenotype, although reactivity with the antibody L26 (CD20) was only found in the primary lesion in many high-grade B-cell lymphomas. Thus, liver involvement is common in haematological malignancies, but the incidence and pattern of infiltration vary amongst the different types. PMID:9842637

Guidelines on Vaccinations in Paediatric Haematology and Oncology Patients  

PubMed Central

Objective. Vaccinations are the most important tool to prevent infectious diseases. Chemotherapy-induced immune depression may impact the efficacy of vaccinations in children. Patients and Methods. A panel of experts of the supportive care working group of the Italian Association Paediatric Haematology Oncology (AIEOP) addressed this issue by guidelines on vaccinations in paediatric cancer patients. The literature published between 1980 and 2013 was reviewed. Results and Conclusion. During intensive chemotherapy, vaccination turned out to be effective for hepatitis A and B, whilst vaccinations with toxoid, protein subunits, or bacterial antigens should be postponed to the less intensive phases, to achieve an adequate immune response. Apart from varicella, the administration of live-attenuated-virus vaccines is not recommended during this phase. Family members should remain on recommended vaccination schedules, including toxoid, inactivated vaccine (also poliomyelitis), and live-attenuated vaccines (varicella, measles, mumps, and rubella). By the time of completion of chemotherapy, insufficient serum antibody levels for vaccine-preventable diseases have been reported, while immunological memory appears to be preserved. Once immunological recovery is completed, usually after 6 months, response to booster or vaccination is generally good and allows patients to be protected and also to contribute to herd immunity.

Haematological and serum biochemical values of southern chamois (Rupicapra pyrenaica).  


Blood samples were taken from 75 free-ranging southern chamois (Rupicapra pyrenaica) captured in drive-nets in Catalonia, north-eastern Spain, and 20 haematological and 24 serum biochemical variables were analysed. The values were similar to those of other species of the Caprinae subfamily, except for cortisol, the concentration of which was higher. The red blood cell count (RBC), platelets and leucocytes, and the concentrations of cortisol, lactate, muscular enzymes and gamma-globulins were higher in summer than in spring, whereas the mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, and the concentrations of cholesterol, total bilirubin and creatinine were lower. Adult males had higher RBCs and haemoglobin values than females in summer, and lower leucocyte, lymphocyte and neutrophil counts than females and yearling males. The concentrations of triglycerides, total bilirubin, lactate, creatinine, urea, chloride and alpha2-globulins were higher in adult males than yearling males. In summer the adult females had higher values for platelets, lymphocytes, cortisol, sodium and muscular enzymes. PMID:16603553

Peromyscus leucopus mice: a potential animal model for haematological studies.  


Peromyscus leucopus mice share physical similarities with laboratory mice Mus musculus (MM) but have higher agility and longer lifespan. We compared domesticated P. leucopus linville (PLL) and M. musculus C57BL/6 (MMB6) mice for cellular composition of peripheral blood (PB), bone marrow (BM) and spleen. PLL mice had significantly fewer platelets and significantly more monocytes in the blood, and notably fewer megakaryocytes in the BM. Spleens of PLL mice were significantly smaller, with 50% fewer cells and reduced 'red pulp'. There was no obvious haematological change in PLL mice between 2-8 and 16-26 months of age, except for a significant increase in blood monocytes. Cellular reactive oxygen species (ROS) content showed no change with age but differed significantly between different cell types. Treating two to eight month-old PLL mice with antioxidant N-acetylcysteine in drinking water for three  months did not affect cellular ROS content, but increased blood leucocytes especially the concentration of monocytes. The low platelets, low megakaryocytes, high monocytes and low splenic erythropoiesis in PLL mice resemble human measurements better than the values seen in MMB6. PMID:25116892

Characteristics of invasive aspergillosis in neutropenic haematology patients (Sousse, Tunisia).  


Although scarce, available data suggest that the epidemiology of invasive aspergillosis (IA) in North Africa differs from northern countries, where more than 80 % is caused by Aspergillus fumigatus. This study aimed at describing the epidemiology of IA in the region of Sousse, Tunisia, and at assessing the usefulness of the available diagnostic tools. For 2 years, clinical and mycological data were prospectively collected from 175 neutropenia episodes of 91 patients hospitalised in the haematology department at the Farhat Hached hospital in Sousse (Tunisia). Screening for galactomannan antigen was positive in 40 % of neutropenia episodes; Aspergillus PCR was positive in 42 % of the tested sera. Nine patients were classified as probable and two as possible IA according to the EORTC/MSG criteria. Twelve patients who prematurely died, had no CT scan and could not be classified. Fifty-six Aspergillus spp. were isolated in 53 (6.5 %) sputa collected from 35 (20 %) patients.

Therapeutic approaches to haematological malignancies in adolescents and young adults.  


Tremendous strides have been made in improving the outcomes of haematological malignancies (HM) over the last three decades, but adolescents and young adult (AYA) patients have not benefitted equally compared to younger and older patients. Excellent outcomes in Hodgkin lymphoma have allowed tailoring of highly effective regimens that limit the incidence of late effects. Early successes in paediatric acute lymphoblastic leukaemia set the stage for a series of studies in young adults utilizing a paediatric-type treatment strategy. These studies have determined that AYAs benefit from paediatric-type chemotherapy regimens. Despite the increased incidence of acute myeloid leukaemia and non-Hodgkin lymphoma in the AYA age group, optimal strategies for these patients have not been systematically pursued. There is renewed interest in improving HM outcomes in AYA patients and this will rely on the development of clinical trials that specifically target these patients. Understanding and addressing the unique psychosocial challenges of this population will be critical in supporting this endeavor. PMID:24007213

Background Malaria is a major mosquito-borne public health problem in Thailand with varied haematological consequences. The study sought to elucidate the haematological changes in people who suspected malaria infection and their possible predictive values of malaria infection. Methods Haematological parameters of 4,985 patients, including 703 malaria-infected and 4,282 non-malaria infected, who admitted at Phop Phra Hospital, Tak Province, an area of malaria endemic transmission in Thailand during 2009 were evaluated. Results The following parameters were significantly lower in malaria-infected patients; red blood cells (RBCs) count, haemoglobin (Hb), platelets count, white blood cells (WBCs) count, neutrophil, monocyte, lymphocyte and eosinophil counts, while mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), Mean corpuscular haemoglobin concentration (MCHC), neutrophil-lymphocyte ratio (NLR), and monocyte-lymphocyte ratio (MLR) were higher in comparison to non-malaria infected patients. Patients with platelet counts?haematological parameters with low platelet, WBCs, and lymphocyte counts being the most important predictors of malaria infection. When used in combination with other clinical and microscopy methods, these parameters could improve malaria diagnosis and treatment. PMID:24898891

Evaluation of the Sysmex pocH-1001 haematology analyser in an outdoor oncology service.  


Since rapid blood count analysis as near patient testing is expanding, we evaluated the use of a Sysmex pocH-100i compact haematology analyser in an outdoor oncology setting according to the recently published International Council for Standardization in Haematology (ICSH) guidelines. In total, 838 blood samples from oncology patients were analysed by pocH-100i and re-analysed by a high-throughput haematology analyser for comparison (Abbott CD-4000 or Sysmex XE-2100) to evaluate in use imprecision, comparability and vote-outs. Imprecision was less than 5%, except for platelet enumeration in the low range (within-run imprecision 7%). Good comparability was found even for platelet enumeration in the low range (r2 = 0.82). Vote-outs were found in 10.6% of examined samples. In conclusion, the Sysmex pocH-100i demonstrates good imprecision conform with former publications, produces reliable results in normal and in lower ranges comparable to the results of high throughput haematology analysers. In a well controlled management plan the Sysmex pocH-100i is suitable for near patient testing in oncology. PMID:20954464

Haematological and biochemical reference intervals for free-ranging brown bears (Ursus arctos) in Sweden  

PubMed Central

Background Establishment of haematological and biochemical reference intervals is important to assess health of animals on individual and population level. Reference intervals for 13 haematological and 34 biochemical variables were established based on 88 apparently healthy free-ranging brown bears (39 males and 49 females) in Sweden. The animals were chemically immobilised by darting from a helicopter with a combination of medetomidine, tiletamine and zolazepam in April and May 2006–2012 in the county of Dalarna, Sweden. Venous blood samples were collected during anaesthesia for radio collaring and marking for ecological studies. For each of the variables, the reference interval was described based on the 95% confidence interval, and differences due to host characteristics sex and age were included if detected. To our knowledge, this is the first report of reference intervals for free-ranging brown bears in Sweden. Results The following variables were not affected by host characteristics: red blood cell, white blood cell, monocyte and platelet count, alanine transaminase, amylase, bilirubin, free fatty acids, glucose, calcium, chloride, potassium, and cortisol. Age differences were seen for the majority of the haematological variables, whereas sex influenced only mean corpuscular haemoglobin concentration, aspartate aminotransferase, lipase, lactate dehydrogenase, ?-globulin, bile acids, triglycerides and sodium. Conclusions The biochemical and haematological reference intervals provided and the differences due to host factors age and gender can be useful for evaluation of health status in free-ranging European brown bears.

Clinical, ultrasonography and haematology of aglepristone-induced mid-gestation pregnancy terminations in rabbits.  


Aglepristone is a safe abortifacient in cats, dogs and rabbits. Although no serious side effects have been reported, there is no information available about the effects of the medicine on haematological parameters. For the first time clinical and ultrasonographic features and haematological profiles were evaluated in rabbits treated with aglepristone 15 and 16 days after mating. Ten healthy 10-14 month-old New Zealand White female rabbits were mated with fertile bucks and pregnancies were con?rmed by ultrasound 15 days later. Of these, 5 does were treated with aglepristone (test group, n = 5) whilst the remaining five (control group, n = 5) were treated with a saline solution (0.9% NaCl). The treatment dose was 10 mg/kg body weight, administered subcutaneously once daily on two consecutive days (day 15 and 16 post mating). Ultrasonographic, clinical and haematological assessments were performed daily. Aglepristone treatment induced embryonic fluid resorptions without foetal death in mid-gestation terminations. Following ultrasonographic and haematological examinations, it was established that aglepristone is a safe abortifacient in rabbits. PMID:23718772

PCR as a screening test for invasive aspergillosis in haematological patients: a pilot study.  


Invasive aspergillosis is a leading cause of morbidity and mortality in immunocompromised patients, particularly in individuals with haematological malignancy and in haematopoietic stem cell transplant recipients. Nowadays, the galactomannan (GM) assay has been widely used as an indication of invasive aspergillosis, even though the test is known to generate false-positive results. The aim of this study was to compare the performance of GM and real-time PCR (qPCR) to detected Aspergillus in blood samples obtained from high-risk haematological patients. Haematological patients were screened twice weekly with GM testing, which was performed by the Platelia ELISA kit. An additional sample of whole blood (4 ml) was obtained for the purpose of qPCR testing. Sixty-four samples from 12 patients with haematopoietic stem cell transplant or haematological malignancy were studied. The overall accordance between GM and qPCR tests was 96.9 % (62 samples). Only two samples showed contradictory results, with positive GM test and negative real-time PCR results. Based on the high concordance between GM and qPCR in terms of negative results, the main utility of qPCR could be in the confirmation of positive results seen with GM testing. PMID:24309908

Background Hematological and biochemical abnormalities are among the most common clinicopathological manifestations of HIV patients on ART. Consequently, the development and assessment of indigenous antiretroviral drugs with minimal abnormalities becomes a necessity. The objective of this investigation was to assess potential haematological and biochemical abnormalities that may be associated with the administration of Winniecure ART in HIV patients undergoing treatment in Nigeria. Fifty (50) confirmed HIV positive ART naïve patients aged 36?±?10 were observed for haematological and biochemical responses for 12 weeks. Haematological responses were assessed thrice at 6 weeks interval using coulter Ac-T differential analyser and biochemical indicators (bilirubin, creatine, urea, amylase, ALT, ALP, AST, albumin) assayed spectrophotometrically. Results The biochemical parameters ALP (P??0.002). Haematological results showed consistent reduction of ESR, eosinophil, absolute and differential lymphocytes, granulocytes and total WBC in the test subjects throughout the assessment period. Conversely, haemoglobin, platelet and PCV increased significantly (P?haematological abnormalities and normal kidney function was unaffected though there were signs of possible abnormal levels of hepatic enzymes beyond 12 weeks of treatment.

Serious haematological toxicity during and after ipilimumab treatment: a case series  

PubMed Central

Introduction Immunotherapy with the anti-cytotoxic T-lymphocyte antigen-4 monoclonal antibody ipilimumab has been shown to improve overall survival in previously treated and treatment-naïve patients with unresectable stage III or IV melanoma. Consistent with its proposed immunomodulating mechanism of action, the most common toxicities associated with ipilimumab therapy are immune-related in nature and include those related to the skin and gastrointestinal tract, with endocrine and hepatic events also frequent. Other rare adverse events, including haematological aberrations, may also occur and can have serious consequences if unrecognised. Here we describe three patients who developed serious haematological adverse events during or after treatment with ipilimumab. Case presentation Three Caucasian patients (two women aged 68 and 49 years and one man aged 70 years) with metastatic melanoma experienced anaemia and/or leukopenia (neutropenia) with toxicity of various grades during or after treatment with ipilimumab, without significant changes to other haematological values. Two of the patients stopped treatment after the third ipilimumab dose, one because of severe anaemia that required blood transfusion and the other due to febrile neutropenia that was treated with antibiotics and granulocyte-macrophage colony-stimulating factor stimulation. The third patient developed anaemia and leukopenia after treatment during the follow-up period. The results of autoimmunity tests performed were positive and corticosteroids were used to treat these events as per side-effects treatment algorithms specifically developed for the management of immune-related adverse events associated with ipilimumab, an approach that was safe and effective. Conclusions Haematological toxicity is a rare but potentially serious immune-related side effect of ipilimumab therapy. However, if promptly recognised and treated, haematological toxicity is manageable and can be reversed with standard corticosteroid treatment as recommended for other ipilimumab immune-related side effects.

Evaluation of the QBC Star centrifugal three-part differential haematology system.  


The QBC Star haematology system includes the QBC Star centrifugal analytical analyser and the QBC Star tube system. Together, they are capable of producing a haematology profile on venous or capillary whole blood. The aim of this study is to compare full blood count (FBC) including differential white cell count performance between the QBC Star analyser and a gold standard Sysmex XE-2100 haematology analyser. The FBC performance was evaluated according to the National Committee for Clinical Laboratory Standards (NCCLS) document H20-A. Imprecision, correlation and linearity studies all showed excellent results. Overall, the haemoglobin, haematocrit, white cell count (WCC) and platelet count parameters showed excellent correlation. Mean corpuscular haemoglobin concentration (MCHC) results showed poor comparability. The white cell differential parameters showed good correlation within certain clinically significant limits. Imprecision for haemoglobin, haematocrit, WCC, MCHC and platelet count was considered acceptable. The re-read function was found to be stable over the five-hour testing period under the authors' laboratory environmental conditions. The subjective assessment by biomedical scientist staff demonstrated that the system was user friendly, required little maintenance, and no user calibration was required. Staff considered the user manual to be excellent. Overall, the QBC Star appears to be an excellent point-of-care (POC) dry haematology analyser that delivers clinically significant nine-parameter complete blood count and will make a good POC analyser for use in field hospitals, research, screening programmes, GP surgeries as well as in emergency and intensive care units. It is a health and safety-friendly analyser considering the fact that it uses dry haematology reagents instead of the bulky wet reagents that are often associated with liquid biohazard waste.

Haematological changes induced by feeding a common food colour, metanil yellow, in albino mice.  


Metanil yellow was administered daily in the food at the rate of 0.0, 0.1, 0.5 and 3.0 g/kg body weight for 180 days to male and female albino mice. No change was observed by the first two doses but feeding of this colour at the rate of 3.0 g/kg body weight led to certain changes in the haematological values. Total erythrocyte count (TEC) and Hb had decreased whereas ESR, MCV, and mean corpuscular haemoglobin (MCH) had increased. These facts suggested the occurrence of normochromic macrocytic anaemia. Differential leukocyte count (DLC) showed marked increase in the number of lymphocytes and monocytes and decrease in the number of neutrophils and eosinophils. Heinz bodies were observed in 80-90% erythrocytes. Other haematological values like total leukocyte count (TLC), platelet count (PC), PCV, MCHC, bleeding time (BT) and coagulation time (CT) were normal. PMID:6836606

Changes in period and cohort effects on haematological cancer mortality in Spain, 1952-2006  

PubMed Central

Background In contrast to other haematological cancers, mortality from non-Hodgkin’s lymphoma and multiple myeloma increased dramatically during the second half of the 20th century in most developed countries. This widespread upward trend remains controversial, as it may be attributable either to progressive improvements in diagnosis and certification or to increasing exposures to little-known but relevant risk factors. Methods To assess the relative contribution of these factors, we analysed the independent effects of age, death period, and birth cohort on haematological cancer mortality rates in Spain across the period 1952-2006. Weighted joinpoint regression analyses were performed to detect and estimate changes in period and cohort curvatures. Results Although mortality rates were consistently higher among men, trends across periods and cohorts were virtually identical in both sexes. There was an early period trend reversal in the 1960s for Hodgkin’s disease and leukaemia, which was delayed to the 1980s for multiple myeloma and the 1990s for non-Hodgkin’s lymphoma. Birth cohort patterns showed a first downturn for generations born in the 1900s and 1910s for all haematological cancers, and a second trend reversal for more recent cohorts born in the 1950s and 1960s for non-Hodgkin’s lymphoma and leukaemia. Conclusions The sustained decline in Hodgkin’s disease mortality and the levelling off in leukaemia seem to be driven by an early period effect linked to improvements in disease treatment, whereas the steep upward trends in non-Hodgkin’s lymphoma and multiple myeloma mortality in Spain are more likely explained by a cohort effect linked to better diagnosis and death certification in the elderly. The consistent male excess mortality across all calendar periods and age groups points to the importance of possible sex-related genetic markers of susceptibility in haematological cancers.

Effects of lichen extracts on haematological parameters of rats with experimental insulin-dependent diabetes mellitus.  


The prevalence of diabetes mellitus in the world is steadily increasing. Oxidative stress contributes to the development of diabetic complications, including diabetic haematological changes. Lichens are used as food supplements and are also used as possible natural antioxidant, antimicrobial and anticancer agents. We hypothesized that antioxidant activity of lichens may decrease hyperglycaemia-induced oxidative stress and prevent the development of diabetic complications, including abnormality in haematological condition. Therefore, the effects of Cetraria islandica water extract (CIWE) and Pseudevernia furfuracea water extract (PFWE) on the haematological parameters of rats with type 1 DM were investigated for the first time in the present study. Control Sprague-Dawley or streptozotocin (STZ)-induced diabetic rats were either untreated or treated with water lichen extracts (5-500 mg/kg body weight (bw)/day) for 2 weeks, starting at 72 h after STZ injection. On day 14, animals were anaesthetized and haematological and metabolic parameters were determined between control and experimental groups. In addition, the total oxidative stress (TOS), a specific indicator of oxidative stress, and the total antioxidant capacity (TAC) were measured by biochemical studies. In diabetic rats, CIWE of 250-500 mg/kg bw dose showed more prominent results when compared with doses of PFWE for TAC. The results obtained in the present study suggested that the antioxidant activities of lichens might be the possible reason behind the observed antihaematological status. However, the protective effect of lichen extracts were inadequate on diabetes-induced microcytic hypochromic anaemia. In addition, the extracts have no effect on metabolic complications. Our experimental data showed that high doses of CIWE and PFWE alone have no detrimental effect on blood cells and TOS status of plasma. Hence, they are safe and suitable for different administration routes. PMID:23114377

Haematological and Biochemical Parameters during the Laying Period in Common Pheasant Hens Housed in Enhanced Cages  

PubMed Central

The development of selected haematological and biochemical parameters during the laying period was monitored in common pheasant hens housed in an enhanced cage system. The cages were enhanced by the addition of two perches and a shelter formed by strips of cloth hanging in the corner of the cage. The results showed significant changes in the haematological and biochemical parameters monitored during egg laying. At the time when laying capacity approached a maximum, a decrease was observed (P < 0.05) in haematocrit, erythrocytes, and haemoglobin values, whereas monocytes, eosinophils, the heterophil/lymphocyte ratio, phosphorus, and calcium exhibited an increase (P < 0.05). At the end of the laying period, an increase (P < 0.05) was recorded in the count of leukocytes, heterophils, lymphocytes and basophils, the heterophil to lymphocyte ratio, and the concentrations of aspartate aminotransferase, cholesterol, phosphorus, and calcium, whereas lower values (P < 0.05) were recorded for haematocrit and plasma total protein in comparison with the values of the indicators at the beginning of the laying period. The results provide new information about dynamic changes in selected haematological and biochemical parameters in clinically healthy common pheasant hens during the laying period. PMID:25121117

Clinical applications of aptamers and nucleic acid therapeutics in haematological malignancies.  


Haematological malignancies result from a heterogeneous mix of genetic mutations and chromosome aberrations and translocations. Targeted therapies, such as the anti-CD20 antibody rituximab, or the BCR-ABL1 inhibitor imatinib, have proven to be effective treatments in the management of some of these malignancies, though relapsing or refractory disease is still common. Nucleic acid-based therapies have also entered the clinical arena, providing an alternative, complementary approach. The forerunner of these therapies were the antisense oligonucleotides, but their scope has expanded to include short-interfering RNA (siRNA), microRNA, decoy oligonucleotides and aptamers. These can be used either as mono-therapeutics, in conjunction with current chemotherapy regimens, or in combination with each other to improve therapeutic efficacy. Not only can these nucleic acid-based therapies silence target genes, they also have the potential of restoring gene function. While challenges remain in delivering effective doses of nucleic acid in vivo, these are steadily being met, suggesting an optimistic future in the treatment of haematological malignancies. This review summarizes the application of nucleic acid-based therapeutics, particularly aptamers, in the diagnosis and treatment of haematological malignancies. PMID:21810089

Stability of haematological parameters and its relevance on the athlete's biological passport model.  


The stability of haematological parameters is crucial to guarantee accurate and reliable data for implementing and interpreting the athlete's biological passport (ABP). In this model, the values of haemoglobin, reticulocytes and out-of-doping period (OFF)-score (Hb-60?Ret) are used to monitor the possible variations of those parameters, and also to compare the thresholds developed by the statistical model for the single athlete on the basis of its personal values and the variance of parameters in the modal group. Nevertheless, a critical review of the current scientific literature dealing with the stability of the haematological parameters included in the ABP programme, and which are used for evaluating the probability of anomalies in the athlete's profile, is currently lacking. In addition, we collected information from published studies, in order to supply a useful, practical and updated review to sports physicians and haematologists. There are some parameters that are highly stable, such as haemoglobin and erythrocytes (red blood cells [RBCs]), whereas others, (e.g. reticulocytes, mean RBC volume and haematocrit) appear less stable. Regardless of the methodology, the stability of haematological parameters is improved by sample refrigeration. The stability of all parameters is highly affected from high storage temperatures, whereas the stability of RBCs and haematocrit is affected by initial freezing followed by refrigeration. Transport and rotation of tubes do not substantially influence any haematological parameter except for reticulocytes. In all the studies we reviewed that used Sysmex instrumentation, which is recommended for ABP measurements, stability was shown for 72 hours at 4 ° C for haemoglobin, RBCs and mean curpuscular haemoglobin concentration (MCHC); up to 48 hours for reticulocytes; and up to 24 hours for haematocrit. In one study, Sysmex instrumentation shows stability extended up to 72 hours at 4 ° C for all the parameters. There are significant differences among methods and instruments: Siemens Advia shows lower stability than Sysmex as regards to reticulocytes. However, the limit of 36 hours from blood collection to analysis as recommended by ABP scientists is reasonable to guarantee analytical quality, when samples are transported at 4 ° C and are accompanied by a certified steadiness of this temperature. There are some parameters that are highly stable, such as haemoglobin and RBCs; whereas others, such as reticulocytes, mean cell volume and haematocrit are more unstable. The stability of haematological parameters might be improved independently from the analytical methodology, by refrigeration of the specimens. PMID:22060177

A new device to relieve venipuncture pain can affect haematology test results  

PubMed Central

Background In vitro diagnostic tests play a key role in patients’ management (e.g., guiding red blood cell transfusions). The aim of this study was to evaluate the impact of an innovative device (Buzzy®) which is claimed to be able to relieve venipuncture pain by means of cold and vibration. This device was applied during collection of venous blood by venipuncture for conventional haematology testing. Materials and methods Blood was drawn from 100 volunteers by a single, expert phlebotomist. A vein was located in the left forearm without applying a tourniquet but using a subcutaneous tissue transilluminator device, so that venous stasis was avoided. Blood samples were collected with a 20G straight needle directly into 4mL K3EDTA vacuum tubes. In sequence, external cold and vibration was established by Buzzy® on the right forearm ?5 cm above the venipuncture site- for 1 minute before venipuncture and continued until the end of the same procedure already performed in the left forearm. Conventional haematological tests were performed using the same instrument (Sysmex® XE-2100D) in all cases. Results When Buzzy® was applied before drawing blood, erythrocyte counts and associated parameters (i.e., haemoglobin and haematocrit) were higher, whereas platelet number, leucocyte count and differential were lower. Statistically and clinically significant differences (P <0.001) were observed for erythrocytes, haemoglobin and haematocrit. Discussion From a practical perspective, cold-induced haemoconcentration promotes the efflux of water, diffusible ions and low molecular weight molecules from the vessel, thus increasing the concentration of other blood analytes at the puncture site. These variations may influence test results, especially for erythrocytes, haemoglobin and haematocrit. The novel Buzzy® device should, therefore, be used with caution when collecting blood for conventional haematological testing because of the observed bias introduced in some parameters.

Modulation of platelet aggregation, haematological and histological parameters by structured lipids on hypercholesterolaemic rats.  


The effect of the consumption of medium-chain fatty acid (MCFA)-rich and polyunsaturated fatty acid (PUFA)-rich mustard oil on platelet aggregation, haematological parameters and the liver was studied in male albino rats. The rats were fed on standard stock diet with control (mustard oil) and experimental oils for 28 days. Haematological examinations in the normal condition showed that there was no significant variation in the platelet count, total white blood cell (WBC) and red blood cell (RBC) counts, haematocrit value and mean cell haemoglobin concentration (MCHC) percentage in the rats fed with control and experimental oils. Haematological examinations in the hypercholesterolaemic condition revealed that there was a significant increase in the platelet count by 39.38% in hypercholesterolaemia, which was decreased by 27.29 and 42.71% by the administration of the experimental oils, respectively. The haemoglobin level was decreased by 5.3%, whereas the haematocrit value was increased by 12.52% in hypercholesterolaemia, which were normalised by treatment with the experimental oils. The platelet aggregation study indicated that the adenosine diphosphate (ADP)-induced platelet aggregation increased by 71.67% in hypercholesterolaemia, but the experimental oils beneficially reduced platelet aggregation by 26.33 and 68.33%, respectively. There was increased total cholesterol, non-high-density lipoprotein (non-HDL) cholesterol and triglyceride levels in liver in hypercholesterolaemia, which was also recovered by the administration of experimental oils. Organopathological examination showed that there was deposition of cholesterol in the liver in the hypercholesterolaemic condition, which was also reduced by treatment with the two experimental oils.

Systemic mastocytosis with associated clonal haematological non-mast cell lineage diseases: a histopathological challenge  

PubMed Central

Aims: Although systemic mastocytosis (SM) with an associated clonal haematological non-mast cell lineage disease (SM-AHNMD) is a major subtype of SM, little is known about its frequency among myelogenous neoplasms, and mastocytosis in particular, or about AHNMD subtype frequencies. Methods: Approximately 19 500 routine bone marrow biopsies were evaluated. Immunostaining with antibodies against tryptase, KIT, and CD25 and molecular analysis for detection of C-KIT point mutations were performed in approximately 550/4100 myelogenous malignancies including mastocytosis, almost all subtypes of myelodysplastic syndrome (MDS), myelodysplastic/myeloproliferative syndrome (MDS/MPD), MPD, and acute myeloid leukaemia (AML). Results: SM was rare—it was diagnosed in only 64 bone marrows (0.3%) and made up 1.5% of myelogenous tumours. SM-AHNMD was the second most frequent subtype (20). SM-AHNMD was never included in the clinical differential diagnoses and was confirmed histologically in most cases only after appropriate immunostaining. The abnormal mast cell phenotype was confirmed by immunohistochemical demonstration of tryptase and CD25 coexpression. The following associated haematological neoplasms were found: MDS/MPS, AML, MPS, MDS, plasma cell myeloma, and unclassifiable myelogenous malignancy. C-KIT point mutations were detected in 16 of 20 cases. Conclusions: SM-AHNMD can be diagnosed histologically in bone marrow trephines only after immunostaining with antibodies against tryptase, KIT, and CD25. Eighteen of 20 AHNMDs were of myeloid origin. C-KIT point mutations were present in 16 of 20 cases. The prognostic relevance of detecting SM associated with another haematological neoplasm remains unclear, but mast cell resistance to most cytoreductive agents is of major importance for treatment planning.

Infection by Brazilian and Dutch swine hepatitis E virus strains induces haematological changes in Macaca fascicularis  

PubMed Central

Background Hepatitis E virus (HEV) has been described as an emerging pathogen in Brazil and seems to be widely disseminated among swine herds. An autochthonous human case of acute hepatitis E was recently reported. To obtain a better understanding of the phenotypic profiles of both human and swine HEV strains, a experimental study was conducted using the animal model, Macaca fascicularis. Methods Six cynomolgus monkeys (Macaca fascicularis) were inoculated intravenously with swine HEV genotype 3 that was isolated from naturally and experimentally infected pigs in Brazil and the Netherlands. Two other monkeys were inoculated with HEV genotype 3 that was recovered from Brazilian and Argentinean patients with locally acquired acute and fulminant hepatitis E. The haematological, biochemical, and virological parameters of all animals were monitored for 67 days. Results Subclinical hepatitis was observed in all monkeys after inoculation with HEV genotype 3 that was recovered from the infected swine and human patients. HEV RNA was detected in the serum and/or faeces of 6 out of the 8 cynomolgus monkeys between 5 and 53 days after inoculation. The mild inflammation of liver tissues and elevations of discrete liver enzymes were observed. Seroconversions to anti-HEV IgM and/or IgG were detected in 7 animals. Reactivities to anti-HEV IgA were also detected in the salivary samples of 3 animals. Interestingly, all of the infected monkeys showed severe lymphopenia and a trend toward monocytosis, which coincided with elevations in alanine aminotransferase and antibody titres. Conclusions The ability of HEV to cross the species barrier was confirmed for both the swine (Brazilian and Dutch) and human (Argentinean) strains, thus reinforcing the zoonotic risk of hepatitis E in South America. Cynomolgus monkeys that were infected with HEV genotype 3 developed subclinical hepatitis that was associated with haematological changes. Haematological approaches should be considered in future studies of HEV infection. PMID:24148233



Biochemical and haematological values for mute swans (Cygnus olor): effects of acute lead poisoning.  


Reference levels of some biochemical and haematological variables were determined for mute swans (Cygnus olor Gmelin). Immaturity was identified as a factor which broadened the references ranges. Blood variables of six acutely lead-poisoned swans were determined and compared with the reference distribution. Protoporphyrin IX, cholesterol and two serum enzymes, lactate dehydrogenase and aspartate amino-transferase, were increased; concentrations of haemoglobin and mean cell haemoglobin concentration indicated hypochromic anaemia in birds with acute lead poisoning. The interpretation and diagnostic value of reference values is discussed. PMID:18766723

The role of primary antifungal prophylaxis in patients with haematological malignancies.  


Invasive fungal infections (IFIs) represent important complications in patients with haematological malignancies. Chemoprevention of IFIs may play an important role in this setting, but in the past decades the majority of antifungal drugs utilized demonstrated poor efficacy, particularly in the prevention of invasive aspergillosis. The new triazoles are very useful antifungal drugs, more suitable for prophylaxis of IFIs than amphotericin B and echinocandins. In this review, the main clinical data about antifungal prophylaxis with fluconazole, itraconazole, voriconazole and posaconazole are analysed. At present, posaconazole appears to be the most efficacious azole in antifungal prophylaxis, particularly in patients with acute myeloid leukaemia. PMID:24372659

An experimental meat-free diet maintained haematological characteristics in sprint-racing sled dogs.  


A dog's nutrient requirements can theoretically be met from a properly balanced meat-free diet; however, proof for this is lacking. Exercise places additional demands on the body, and dogs fed a meat-free diet may be at increased risk of developing sports anaemia. We hypothesised that exercising dogs would remain in good health and not develop anaemia when fed a nutritionally balanced meat-free diet. To this end, twelve sprint-racing Siberian huskies were fed either a commercial diet recommended for active dogs (n 6), or a meat-free diet formulated to the same nutrient specifications (n 6). The commercial diet contained 43 % poultry meal, whereas soyabean meal and maize gluten made up 43 % of the meat-free diet, as the main protein ingredients. Dogs were fed these diets as their sole nutrient intake for 16 weeks, including 10 weeks of competitive racing. Blood samples were collected at weeks 0, 3, 8 and 16, and veterinary health checks were conducted at weeks 0, 8 and 16. Haematology results for all dogs, irrespective of diet, were within normal range throughout the study and the consulting veterinarian assessed all dogs to be in excellent physical condition. No dogs in the present study developed anaemia. On the contrary, erythrocyte counts and Hb values increased significantly over time (P < 0.01) in both groups of dogs. The present study is the first to demonstrate that a carefully balanced meat-free diet can maintain normal haematological values in exercising dogs. PMID:19480731

Guideline on the prevention of secondary central nervous system lymphoma: British Committee for Standards in Haematology.  


The guideline group was selected to be representative of UK-based medical experts. Ovid MEDLINE, EMBASE and NCBI Pubmed were searched systematically for publications in English from 1980 to 2012 using the MeSH subheading 'lymphoma, CNS', 'lymphoma, central nervous system', 'lymphoma, high grade', 'lymphoma, Burkitt's', 'lymphoma, lymphoblastic' and 'lymphoma, diffuse large B cell' as keywords, as well as all subheadings. The writing group produced the draft guideline, which was subsequently revised by consensus by members of the Haemato-oncology Task Force of the British Committee for Standards in Haematology (BCSH). The guideline was then reviewed by a sounding board of ~50 UK haematologists, the BCSH and the British Society for Haematology (BSH) Committee and comments incorporated where appropriate. The 'GRADE' system was used to quote levels and grades of evidence, details of which can be found in Appendix I. The objective of this guideline is to provide healthcare professionals with clear guidance on the optimal prevention of secondary central nervous system (CNS) lymphoma. The guidance may not be appropriate to patients of all lymphoma sub-types and in all cases individual patient circumstances may dictate an alternative approach. Acronyms are defined at time of first use. PMID:24033102

A panel of cancer-testis genes exhibiting broad-spectrum expression in haematological malignancies  

PubMed Central

Cancer-testis (CT) antigens/genes show restricted expression in normal tissues but widespread expression in many tumour types. This, coupled with their ability to induce cytotoxic T-lymphocyte responses, makes them attractive vaccine candidates. Following our identification of PASD1, we have used RT-PCR to analyse the mRNA expression profile of a large panel of CT genes in cell lines derived from haematological malignancies, and have studied Sp17 protein expression in the same cell lines and diffuse large B-cell lymphoma (DLBCL) biopsies. Our extensive analysis revealed multiple CT transcripts exhibiting widespread expression across cell lines derived from 21 B- and 4 T-cell malignancies. The broadest mRNA expression profiles were observed for the following eight CT genes: Sp17 (25/25), PRAME (25/25), CSAGE (24/25), PASD1 (22/25), CAGE/DDX53 (19/25), CTAGE1 (19/25), HAGE/DDX43 (16/25) and PLU-1/JARID1B (15/25). Cell lines derived from more aggressive lymphoma subtypes generally expressed CT transcripts at higher frequency. Sp17 protein was detected in a number of cell lines and in six of eleven (54.5%) DLBCL biopsies. Analysis of Sp17 protein expression, by immunohistochemistry and Western blotting, broadens the scope of this CT antigen as a potentially relevant clinical target in haematological malignancies. Further studies of protein expression are now needed to validate these antigens as vaccine candidates. PMID:20726502

Differences in incidence and trends of haematological malignancies in Japan and the United States.  


The incidence of a malignant disease reflects the genetic and cumulative exposure to the environment of a population. Therefore, evaluation of the incidence and trends of a disease in different populations may provide insights into its aetiology and pathogenesis. To evaluate the incidence of haematological malignancies according to specific subtypes, we used population-based registry data in Japan (N = 125 148) and the United States (US; N = 172 925) from 1993 to 2008. The age-adjusted incidence of haematological malignancies in Japan was approximately one-half that in the US but has been increasing significantly, whereas no significant change was seen in the US [annual percent change (95% C confidence interval): Japan, +2·4% (1·7, 3·1); US, +0·1% (-0·1, 0·2)]. Hodgkin lymphoma (HL) and non-Hodgkin lymphoma (NHL) showed the largest differences in incidence, with the most remarkable differences observed for chronic lymphocytic leukaemia, HL-nodular sclerosis, mycosis fungoides and cutaneous T-cell lymphoma. HL and NHL are increasing substantially in Japan but not in the US, suggesting that environmental exposures, such as Westernization of the life style may be causing this increase. Differences in the incidence and trends for specific subtypes also showed a marked contrast across subtypes, which, in turn, may provide significant new insights into disease aetiology in the future.

Survival following relapse in childhood haematological malignancies diagnosed in 1974-2003 in Yorkshire, UK  

PubMed Central

We examined population-based information on relapsed childhood haematological cancers, investigating factors that might influence both overall survival and survival following relapse among the 1177 children (0–14 years) diagnosed with a haematological malignancy in Yorkshire from 1974 to 2003, of whom 342 (29%) relapsed at least once. Leukaemia patients from more deprived areas were significantly less likely to relapse (odds ratio=0.54, 95% confidence interval 0.32–0.93 for most deprived quintile vs least deprived quintile; Ptrend=0.06), especially those with acute myeloid leukaemia (P=0.04). Neither ethnic group nor distance to the main treatment centre was associated with risk of relapse. Overall, patients who relapsed at least once had 5-year survival rates of 46% (41–51%) compared with 79% (76–81%) of those who did not. Five-year survival rates from the time of first relapse increased from 20% in 1974–1983 to 45% in 1984–2003. Length of first remission was a strong predictor of survival for leukaemia with a 46% reduced risk of death for every additional year of event-free survival. Of children who experienced a relapse, 46% survived at least 5 years, whereas just under half of patients survived 5 years beyond disease recurrence. This provides a baseline for future comparisons and demonstrates that relapsed childhood cancer need not imply a poor outcome. PMID:17342086

Abnormal biochemical and haematological indices in trypanosomiasis as a threat to herd production.  


Blood samples were collected from 46 domestic ruminants comprising of 23 trypanosomiasis infected and 23 uninfected control groups to study some biochemical and haematological effects of trypanosomiasis under natural condition. The effect of trypanosome infection in ruminant animals showed that infected animals had significantly lower (P<0.05) packed cell volume, erythrocyte count and higher (P<0.01) mean cell volumes than uninfected animals. Leucocytosis, reticulocytosis and thrombocytopenia were also observed. The infection also produced a decrease in albumin (P<0.001), significant increase in total protein and bilirubin levels. These changes were not seen in the animals that were not infected. The outcome of the work shows that herds are severely affected by the disease, and therefore supports the prospect of routine check as an epidemiologic tool in trypanosomiasis based on its abnormal effects in blood.

Selected haematological and plasma chemistry parameters in juvenile and adult degus (Octodon degus).  


Thirty-five juvenile (mean age 6.3 weeks) and 35 adult (mean age 2.0 years) healthy degus (Octodon degus) were studied to investigate selected haematological and plasma biochemistry parameters. Animals were anaesthetised with isoflurane, and blood was withdrawn from the cranial vena cava. Erythrocyte, haematocrit and neutrophil counts (including the percentage of neutrophils) were significantly higher in the adult degus than in the juveniles. In contrast, the reticulocyte count, mean corpuscular volume, mean corpuscular haemoglobin, number of platelets and percentage of lymphocytes were significantly lower in the adult animals. Total protein and globulin levels were significantly higher in the adult degus. The albumin:globulin ratio and plasma levels of urea nitrogen, cholesterol, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, potassium, total calcium and inorganic phosphorus were significantly lower in adults than in juveniles.

The Effect of Cement Dust Exposure on Haematological Parameters of Cement Factory workers in Nalagonda, Andhra Pradesh.  

NASA Astrophysics Data System (ADS)

This study was measured on haematological parameters in workers exposed to cement dust in order to test the the hypothesis and to identify a simple, readily available, cost effective screening test that could help in identifying the presence of disease, its severity, that Cement dust exposure may perturb these functions related to their workplace.Assesment of haematological parameters were performed in 100exposed workers occupationally exposed to cement dust and 50 matched unexposed controls with ages ranging from 20-35, 35-50, 50-65 years. The blood samples were taken from them and percentage of hemoglobin, Lymphocytes / monocytes count were analysed.The hemoglobin percentage of exposed workers were significantly lower(P<0.05).Lymphocytes/Monocytes counts of exposed workers was insignificant (P<0.05).These results suggest that long term occupational exposure to cement dust may perturb haemopoietic function.

A new frontier in haematology - combining pharmacokinetic with pharmacodynamic factors to improve choice and dose of drug.  


The issue of tailored dosing adjusted according to a range of patient-specific factors other than bodyweight or body surface area is of large and increasing clinical and financial concern. Even if it is known that dosing alterations are likely to be required for parameters such as body composition, gender and pharmacogenetics, the amount of dosing change is unknown. Thus, pharmacokinetically guided dosing is making a resurgence, particularly in areas of medicine where there are cost constraints or safety issues, such as in haematology medications. However, the evidence to support the behaviour is minimal, particularly when long-term outcomes are considered. In haematology, there are particular issues around efficacy, toxicity and overall cost. Newer targeted agents, such as the monoclonal antibody rituximab and the tyrosine kinase inhibitor imatinib, whilst clearly being highly effective, are dosed on a milligram per square metre (rituximab) or fixed dose basis (imatinib), regardless of body composition, tumour aspects or comorbidity. This review questions this practice and raises important clinical issues; specifically, the clinical potential for combined pharmacokinetically and pharmacodynamically guided dosing of new targeted agents in haematological malignancies. This pharmacokinetically and pharmacodynamically guided dosing is an emerging area of clinical pharmacology, driven predominantly by toxicity, efficacy and cost issues, but also because reasonable outcomes are being noted with more appropriately dosed older medications adjusted for patient-specific factors. Clinical trials to investigate the optimization of rituximab dose scheduling are required. PMID:24433338

This experiment was conducted to determine the effect of aqueous extract of Telfairia occidentalis (Fluted Pumpkin) leaf on the performance and haematological indices of starter broilers. A total of 200, 8-day-old broiler chicks were randomly allotted to five (5) treatments, each with 4 replicate groups containing 10 chicks and fed with standard starter broiler diets. Telfaria occidentalis leaves extract (FPLE) was added at 0, 40, 80, 120, and 160?mL/litre of drinking water. Growth performance and haematological indices were evaluated. Results showed that there was significant (P < 0.05) difference in weight gain, feed conversion, and protein efficiency ratios of the birds among the treatments. Birds fed 80?ml FPLE/litre of water had significantly the highest weight gain and the best feed conversion and protein efficiency ratios. There was no significant (P > 0.05) variations in the feed and water intakes of the birds. Results also show no significant (P > 0.05) difference in haematological indices of birds among the treatments. The results of this study indicate that, for enhanced weight gain and feed conversion efficiency, birds should be fed 80?mL FPLE/litre of water. PMID:23738128

Role of Haematological Parameters as an Indicator of Acute Malarial Infection in Uttarakhand State of India  

PubMed Central

Background Malaria may be associated with complications which may be avoided by early diagnosis and treatment. Microscopic diagnosis showing presence of malarial parasites is needed for confirmation which at times may be unreliable and requires technical expertise. The present study was conducted to statistically analyze the haematological parameters including platelet indices which can give initial hint for malarial infection and therefore prompt the laboratory physician for active search of the parasite microscopically. Methods A retrospective study was conducted which included 334 cases of acute malaria caused by Plasmodium vivax, falciparum and dual infection along with 100 cases of control. Routine haematological parameters along with platelet indices (MPV and PDW) which are easily available on automated cell counter were statistically analyzed to assess their role as indicators for malaria. Results Leukocyte count and platelet count were significantly lower in cases of acute malaria in comparison to controls (p value <0.001). Platelet count<150×109/l showed 87.2% sensitivity, 65% specificity, 89.3% positive predictive value and 2.49 likelihood ratio for the infection. PDW of 6–10 and MPV>8 fl had 71.9% and 61.5% sensitivity and 78.2% and 77.7% positive predictive value respectively for infection. Platelet count <150×109/l and MPV>8 fl was comparatively more sensitive indicator for vivax (88% and 70.8% respectively) than falciparum (84.8% and 50.4% respectively) and PDW 6–10 was more sensitive indicator for falciparum (82.6%) than vivax (69.5%) infection. Conclusion Thrombocytopenia (<150×109/l) and low leukocyte count (<4×109/l) may be used as probable indicator for malaria in endemic countries. Higher MPV (>8 fl) and PDW of 6–10 also show considerable sensitivity for malarial infection. In addition, thrombocytopenia (<150×109/l) and higher MPV (>8 fl) was more sensitive for vivax infection while PDW 6–10 was more sensitive for falciparum infection. PMID:23350022

Multivitamin supplementation improves haematologic status in children born to HIV-positive women in Tanzania  

PubMed Central

Introduction Anaemia is prevalent among children born to HIV-positive women, and it is associated with adverse effects on cognitive and motor development, growth, and increased risks of morbidity and mortality. Objective To examine the effect of daily multivitamin supplementation on haematologic status and mother-to-child transmission (MTCT) of HIV through breastfeeding. Methods A total of 2387 infants born to HIV-positive women from Dar es Salaam, Tanzania were enrolled in a randomized, double-blind, placebo-controlled trial, and provided a daily oral supplement of multivitamins (vitamin B complex, C and E) or placebo at age 6 weeks for 24 months. Among them, 2008 infants provided blood samples and had haemoglobin concentrations measured at baseline and during a follow-up period. Anaemia was defined as haemoglobin concentrations<11 g/dL and severe anaemia<8.5 g/dL. Results Haemoglobin concentrations among children in the treatment group were significantly higher than those in the placebo group at 12 (9.77 vs. 9.64 g/dL, p=0.03), 18 (9.76 vs. 9.57 g/dL, p=0.004), and 24 months (9.93 vs. 9.75 g/dL, p=0.02) of follow-up. Compared to those in the placebo group, children in the treatment group had a 12% lower risk of anaemia (hazard ratio (HR): 0.88; 95% CI: 0.79–0.99; p=0.03). The treatment was associated with a 28% reduced risk of severe anaemia among children born to women without anaemia (HR: 0.72; 95% CI: 0.56–0.92; p=0.008), but not among those born to women with anaemia (HR: 1.10; 95% CI: 0.79–1.54; p=0.57; p for interaction=0.007). One thousand seven hundred fifty three infants who tested HIV-negative at baseline and had HIV testing during follow-up were included in the analysis for MTCT of HIV. No association was found between multivitamin supplements and MTCT of HIV. Conclusions Multivitamin supplements improve haematologic status among children born to HIV-positive women. Further trials focusing on anaemia among HIV-exposed children are warranted in the context of antiretroviral therapy. PMID:23948440

Changes in haematological profile of common pheasant (Phasianus colchicus) induced by transit to pheasantry.  


The aim of this study was to assess haematological changes in hand-reared pheasants (Phasianus colchicus) transported from intensive housing facilities to a pheasantry. Selected haematological parameters were monitored in a group of 100 pheasants (50 males and 50 females) aged of 9 weeks that were transported for 4 hours by a covered lorry in crates, with a total body weight of 12 +/- 0.5 kg per crate (Group C12 - floor space: 290 cm2/kg) and with a total body weight of 18 +/- 0.5 kg per crate (Group C18 - floor space: 195 cm2/kg). Blood samples were taken from 10 randomly selected males and 10 females before transport (CON group) and 20 hours after transport (C12 and C18 groups). Examinations consisted in determining the total erythrocyte and leukocyte counts, haematocrit values, haemoglobin levels and differential leukocyte counts, whereby the proportions of heterophil, basophil and eosinophil granulocytes, lymphocytes and monocytes of the total leukocytes were computed. The changes in the parameters of red blood cell count were manifested by an increase (P < 0.01) in the haemoglobin level, MCH (mean cell haemoglobin) and MCHC (mean cell haemoglobin concentration) values and a decrease (P < 0.01) in the total erythrocyte count and haematocrit level in both C12 and C18 pheasants, when compared with the control group of non-transported pheasants. C18 pheasants exhibited also a significant increase (P < 0.05) in MCV (mean cell value) value. When analyzing differential leukocyte counts, C18 pheasants showed a decrease (P < 0.01) in heterophil counts and H/L ratio, whereas values in C12 pheasants did not differ from the non-transported control group. Individual counts of lymphocytes were decreased (P < 0.05) in C12 pheasants, whereas basophil counts were increased (P < 0.01) in both C12 and C18 pheasants. Total leukocyte count was decreased (P < 0.01) in C12 and C18 pheasants. In conclusion, the specific requirements of pheasants, as primarily wild animals, for the density in crates should be respected during transportation and they should be transported at lower densities than other poultry species, at least 290 cm2/kg live weight should be provided.

Effect of azadirachtin on haematological and biochemical parameters of Argulus-infested goldfish Carassius auratus (Linn. 1758).  


Argulosis hampers aquaculture production and alters the host physiology and growth. Azadirachtin is recognized as a potential antiparasitic agent against Argulus sp. The present study aimed to investigate the effect of different concentration of azadirachtin solution on haematological and serum biochemical parameters of Argulus-infested goldfish Carassius auratus. Ninety Argulus-infested goldfish were randomly divided into six equal groups. Fish of group 1-5 were treated with azadirachtin solution through bath of 1, 5, 10, 15 and 20 mg L(-1) as T1, T2, T3, T4 and T5, respectively, and group 6 was exposed to 2% DMSO solution without azadirachtin and considered as negative control T0(-). Along with six treatment groups, a positive control T0(+) of healthy goldfish free from Argulus infestation was also maintained. Parasitic mortality was evaluated after 3 days of consecutive bath treatment. After 7 days of post-treatment, the blood and serum were drawn from each of the treatment groups and haematological and serum biochemical parameters were evaluated. Total leucocyte count (TLC), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), blood glucose, total protein (TP), globulin, serum glutamate oxaloacetate transaminase (SGOT) and serum glutamate pyruvate transaminase (SGPT) were significantly (p < 0.05) high in negative control group when compared with positive control group. It could be concluded that Argulus infestation altered marked haematological and serum biochemical parameters. However, in treated groups complete elimination of Argulus was found in T4 and T5 groups. Also significant (p < 0.05) reduction in haematological and serum biochemical parameters of all the treatment groups were recorded in comparison with negative control group. In addition, T4 and T5 groups showed significantly (p < 0.05) high superoxide dismutase (SOD), catalase, total erythrocyte count (TEC) and haemoglobin (Hb). However, higher mean corpuscular haemoglobin concentration (MCHC), blood glucose and lactate dehydrogenase (LDH) levels in T5 group revealed that higher concentration of azadirachtin have notable effects on activity of vital tissues function and physiology of the host. Argulus spp. from infested goldfish could be eliminated using bath treatment with solution of azadirachtin having concentration of 15 mg L(-1) and that also shifted haematological and serum biochemical parameters towards homeostasis.

Assessment of haematological parameters in HIV-infected and uninfected Rwandan women: a cross-sectional study  

PubMed Central

Objectives Although haematological abnormalities are common manifestations of HIV infection, few studies on haematological parameters in HIV-infected persons have been undertaken in sub-Saharan Africa. The authors assessed factors associated with haematological parameters in HIV-infected antiretroviral-naïve and HIV-uninfected Rwandan women. Study design Cross-sectional analysis of a longitudinal cohort. Setting Community-based women's associations. Participants 710 HIV-infected (HIV+) antiretroviral-naïve and 226 HIV-uninfected (HIV?) women from the Rwanda Women's Interassociation Study Assessment. Haematological parameters categorised as (abnormal vs normal) were compared by HIV status and among HIV+ women by CD4 count category using proportions. Multivariate logistic regression models using forward selection were fit. Results Prevalence of anaemia (haemoglobin (Hb) <12.0?g/dl) was higher in the HIV+ group (20.5% vs 6.3%; p<0.001), and increased with lower CD4 counts: ?350 (7.6%), 200–349 (16%) and <200 cells/mm3 (32.2%). Marked anaemia (Hb <10.0?g/dl) was found in 4.2% of HIV+ and none of the HIV? women (p<0.001), and was highest in HIV+ women with CD4 <200 cells/mm3 (8.4%). The HIV+ were more likely than HIV? women (4.2 vs 0.5%, respectively, p=0.002) to have moderate neutropenia with white blood cells <2.0×103 cells/mm3 and 8.4% of HIV+ women with CD4 <200 cells/mm3 had moderate neutropenia. In multivariate logistic regression analysis, BMI (OR 0.87/kg/m2, 95% CI 0.82 to 0.93; p<0.001), CD4 200–350 vs HIV? (OR 3.59, 95% CI 1.89 to 6.83; p<0.001) and CD4 <200 cells/mm3 vs HIV? (OR 8.09, 95% CI 4.37 to 14.97; <0.001) had large independent associations with anaemia. There were large independent associations of CD4 <200 cells/mm3 vs HIV? (OR 7.18, 95% CI 0.78 to 65.82; p=0.081) and co-trimoxazole and/or dapsone use (OR 5.69, 95% CI 0.63 to 51.45; p=0.122) with moderate neutropenia. Conclusions Anaemia was more common than neutropenia or thrombocytopenia in the HIV-infected Rwandan women. Future comparisons of haematological parameters in HIV-infected patients before and after antiretroviral therapy initiation are warranted. PMID:23169875

Berberine-induced haemolysis revisited: safety of Rhizoma coptidis and Cortex phellodendri in chronic haematological diseases.  


Two commonly used berberine-containing Chinese herbs, Rhizoma coptidis (RC) and Cortex phellodendri (CP), have been banned in Singapore for the past three decades due to implication of berberine in aggravating jaundice and kernicterus in neonates with glucose-6-phosphate dehydrogenase deficiency. Here we conducted a single arm, phase I/II clinical study on Chinese herbal medicine for patients with chronic cytopenic haematological conditions and we analysed a subset of 20 patients who also had RC, CP or both in their herbal concoction. We found no organ toxicity or electrolyte imbalance in these 20 patients where RC was administered for 1055 patient-days and CP for 1252 patient-days. In three patients with thalassemia intermedia, transient elevation in serum bilirubin level was observed but this was not associated with any aggravation of anaemia or liver dysfunction. A review of the literature found conflicting evidence of varying levels either supporting or refuting the allegation of neonatal jaundice and kernicterus caused by berberine. There were, however, very few clinical reports of adverse reaction attributable to RC or CP in oral TCM concoction. We conclude that based on traditional dosage and indication, the use of RC and CP in oral concoction is safe. PMID:22002596

The stress response of frequently electroejaculated rams to electroejaculation: hormonal, physiological, biochemical, haematological and behavioural parameters.  


Electroejaculation (EE) is a technique widely used to collect semen in ruminants, which produces a stress response with negative effects on animal welfare. The aim of this paper was to characterize the stress response during conventional EE in rams that have been frequently electroejaculated. Blood samples were collected since 20 min before and until 120 min after electroejaculating 10 rams. Electroejaculation affected hormone concentration, as cortisol increased, and testosterone decreased after EE. Heart and respiratory rate increased 10 min after EE. Several blood parameters, such as glycaemia, an increase in total protein and creatine kinase concentrations and a decrease in haematocrit, haemoglobin, red blood cell and alkaline phosphatase concentrations. The rams vocalized 13.8 ± 2.4 times, and the largest length of vocalizations during EE was associated with the numbers of pulses in which the rams ejaculated. In this paper, we provide a complete characterization of the stress response to EE in rams. We showed that although rams have been frequently electroejaculated, an important stress response including changes in respiratory rate, testosterone concentrations, haematological and biochemical parameters were observed, besides the changes in cortisol concentrations and heart rate, suggesting that rams were not habituated to EE. In addition, we described the main parameters of vocalizations and its relation with the moment of EE. The information displayed on the frequent use of EE in the rams should be considered in relation to the welfare implications. PMID:21092067

Atlas of Genetics and Cytogenetics in Oncology and Haematology in 2013  

PubMed Central

The Atlas of Genetics and Cytogenetics in Oncology and Haematology ( is a peer-reviewed internet journal/encyclopaedia/database focused on genes implicated in cancer, cytogenetics and clinical entities in cancer and cancer-prone hereditary diseases. The main goal of the Atlas is to provide review articles that describe complementary topics, namely, genes, genetic abnormalities, histopathology, clinical diagnoses and a large iconography. This description, which was historically based on karyotypic abnormalities and in situ hybridization (fluorescence in situ hybridization) techniques, now benefits from comparative genomic hybridization and massive sequencing, uncovering a tremendous amount of genetic rearrangements. As the Atlas combines different types of information (genes, genetic abnormalities, histopathology, clinical diagnoses and external links), its content is currently unique. The Atlas is a cognitive tool for fundamental and clinical research and has developed into an encyclopaedic work. In clinical practice, it contributes to the cytogenetic diagnosis and may guide treatment decision making, particularly regarding rare diseases (because they are numerous and are frequently encountered). Readers as well as the authors of the Atlas are researchers and/or clinicians. PMID:23161685

Basic haematological values in antelopes--II. The Hippotraginae and the Tragelaphinae.  


Basic haematological values in 49 animals of five species of the subfamily Hippotraginae, namely the roan antelope Hippotragus equinus, sable antelope Hippotragus niger, adax antelope Addax nasomaculatus, gemsbok oryx Oryx gazella gazella and scimitar horned oryx Oryx damah and in 51 individuals of five species in the subfamily Tragelaphinae, including the bushbuck Tragelaphus scriptus, nyala Tragelaphus angasi, greater kudu Tragelaphus strepsiceros, cape eland Tautotragus oryx and bongo Bocercus euryceros are reported. The erythrocyte counts were in the range of 12.62 X 10(12)/l in the gemsbok oryx to 6.44 X 10(12)/l in the bongo, the haematocrit values varied from 0.488 in the nyala to 0.380 in the roan antelope and for the haemoglobin highest levels (164.0 g/l) were noted in the adax antelope, and the lowest (105.5 g/l) in the bongo. Leukocyte counts were found mostly in the normal human range and varied from 7.17 X 10(9)/l in the adax antelope to 4.05 X 10(9)/l in the nyala, only in the greater kudu decreased values of 3.02 X 10(9) were estimated. These results are compared with findings taken from the literature, and with the normal human range. PMID:6149054

Effect of Intensity of Cigarette Smoking on Haematological and Lipid Parameters  

PubMed Central

Background: Smoking is the single largest preventable cause of disease and premature death and major tobacco related diseases like cancer costs India more than Rs.308.33 billion per year. Cigarette smoking increases the total peripheral blood leukocyte count but its effect on other haematological parameters is largely unexplored.. Objective: To study the effect of smoking and its intensity on hematological and lipid parameters. Materials and Methods: This cross sectional study included 40 cigarette smokers and 40 non-smokers in the age range of 25 and 40 years at SRM Medical College, Kattangulathur, Tamilnadu, India. In this study the volunteers were otherwise healthy and the smokers were enquired about their intensity of smoking using smoking index. Common hematological and lipid parameters were measured in all subjects. Comparison of smoking status and its intensity among the study subjects were analysed using t-test and ANOVA.. Results: There is a significant increase in levels of haemoglobin, hematocrit, total leukocyte count, total cholesterol, triglycerides, low density lipoprotein (LDL), very low density lipoprotein (VLDL) and reduced levels of high density lipoprotein (HDL) among the smokers. Heavy smokers showed significant dyslipidemia,increase in red blood cell count, total leukocyte count and neutrophil count. Conclusion: Increase in hemoglobin, hematocrit, total leucocyte count and dyslipidemia were found significant among smokers and in heavy smokers there is dyslipidemia with increased RBC count, total leukocyte count with specific increase in neutrophils. As per the existing literature, these changes may lead to future fatal cardiac diseases among the smokers.

The Psychosocial Experience of Adolescents with Haematological Malignancies in Jordan: An Interpretive Phenomenological Analysis Study  

PubMed Central

The qualitative research method of interpretive phenomenological analysis was used to explore the lived experience of 14 Jordanian adolescents with haematological malignancies. They were admitted to two hospitals in Jordan and were interviewed for this study twice during the first six months after receiving their diagnosis. The results of this study revealed three themes: (1) Being in hospital, (2) The changing self, and (3) Fearing the unknown. When the participants were hospitalised due to their illness they were removed from their families and friends and prevented from engaging in their normal daily routine. Participants also reported receiving limited emotional and psychological support from health team members during hospitalisation. From the onset of cancer treatments, the bio-psychosocial side effects of the chemotherapy became one of the most distressing factors for participants affecting all aspects of their life and generated uncertainty about their future. The findings add to existing understanding of the lived experiences of cancer patients and in particular Jordanian adolescents. They provide a valuable insight for clinicians into improvements in service delivery to this group of patients. PMID:24550700



Prenatal ultrasound heating impacts on fluctuations in haematological analysis of Oryctolagus cuniculus  

PubMed Central

Prenatal Ultrasound (US) is commonly used as a routine procedure on pregnant women. It is generally perceived as a safe procedure due to the use of non-ionizing radiation. However, the neurotoxicity of diagnostic prenatal US was detected to have a correlation with high susceptibility to early developing fetus. This research involved in vivo experimental model by using 3rd trimester pregnant Oryctolagus cuniculus and exposing them to US exposures for 30, 60, and 90 minutes at their gestational day (GD) 28-29. The output power and intensities, spatial peak temporal average intensity (ISPTA) of US were varied from 0.4 to 0.7 W and 0.13 to 0.19 W/cm2 respectively were tested initially in free-field, water. Haematological analysis was carried out to detect any changes in blood constituents. Statistically significant differences were detected in red blood cell (RBC) count (P<0.001), haemoglobin (Hb) concentration (P<0.001) and also platelet (PLT) count (P<0.001) in newborn of Oryctolagus cuniculus. These findings indicate the possibility of US heating in causing defects on studied animal. PMID:24273744

Detection of Invasive Pulmonary Aspergillosis in Haematological Malignancy Patients by using Lateral-flow Technology  

PubMed Central

Invasive pulmonary aspergillosis (IPA) is a leading cause of morbidity and mortality in haematological malignancy patients and hematopoietic stem cell transplant recipients1. Detection of IPA represents a formidable diagnostic challenge and, in the absence of a 'gold standard', relies on a combination of clinical data and microbiology and histopathology where feasible. Diagnosis of IPA must conform to the European Organization for Research and Treatment of Cancer and the National Institute of Allergy and Infectious Diseases Mycology Study Group (EORTC/MSG) consensus defining "proven", "probable", and "possible" invasive fungal diseases2. Currently, no nucleic acid-based tests have been externally validated for IPA detection and so polymerase chain reaction (PCR) is not included in current EORTC/MSG diagnostic criteria. Identification of Aspergillus in histological sections is problematic because of similarities in hyphal morphologies with other invasive fungal pathogens3, and proven identification requires isolation of the etiologic agent in pure culture. Culture-based approaches rely on the availability of biopsy samples, but these are not always accessible in sick patients, and do not always yield viable propagules for culture when obtained. An important feature in the pathogenesis of Aspergillus is angio-invasion, a trait that provides opportunities to track the fungus immunologically using tests that detect characteristic antigenic signatures molecules in serum and bronchoalveolar lavage (BAL) fluids. This has led to the development of the Platelia enzyme immunoassay (GM-EIA) that detects Aspergillus galactomannan and a 'pan-fungal' assay (Fungitell test) that detects the conserved fungal cell wall component (1 ?3)-?-D-glucan, but not in the mucorales that lack this component in their cell walls1,4. Issues surrounding the accuracy of these tests1,4-6 has led to the recent development of next-generation monoclonal antibody (MAb)-based assays that detect surrogate markers of infection1,5. Thornton5 recently described the generation of an Aspergillus-specific MAb (JF5) using hybridoma technology and its use to develop an immuno-chromatographic lateral-flow device (LFD) for the point-of-care (POC) diagnosis of IPA. A major advantage of the LFD is its ability to detect activity since MAb JF5 binds to an extracellular glycoprotein antigen that is secreted during active growth of the fungus only5. This is an important consideration when using fluids such as lung BAL for diagnosing IPA since Aspergillus spores are a common component of inhaled air. The utility of the device in diagnosing IPA has been demonstrated using an animal model of infection, where the LFD displayed improved sensitivity and specificity compared to the Platelia GM and Fungitell (1 ? 3)-?-D-glucan assays7. Here, we present a simple LFD procedure to detect Aspergillus antigen in human serum and BAL fluids. Its speed and accuracy provides a novel adjunct point-of-care test for diagnosis of IPA in haematological malignancy patients. PMID:22473419

A Genome-wide screen identifies frequently methylated genes in haematological and epithelial cancers  

PubMed Central

Background Genetic as well as epigenetic alterations are a hallmark of both epithelial and haematological malignancies. High throughput screens are required to identify epigenetic markers that can be useful for diagnostic and prognostic purposes across malignancies. Results Here we report for the first time the use of the MIRA assay (methylated CpG island recovery assay) in combination with genome-wide CpG island arrays to identify epigenetic molecular markers in childhood acute lymphoblastic leukemia (ALL) on a genome-wide scale. We identified 30 genes demonstrating methylation frequencies of ?25% in childhood ALL, nine genes showed significantly different methylation frequencies in B vs T-ALL. For majority of the genes expression could be restored in methylated leukemia lines after treatment with 5-azaDC. Forty-four percent of the genes represent targets of the polycomb complex. In chronic myeloid leukemia (CML) two of the genes, (TFAP2A and EBF2), demonstrated increased methylation in blast crisis compared to chronic phase (P < 0.05). Furthermore hypermethylation of an autophagy related gene ATG16L2 was associated with poorer prognosis in terms of molecular response to Imatinib treatment. Lastly we demonstrated that ten of these genes were also frequently methylated in common epithelial cancers. Conclusion In summary we have identified a large number of genes showing frequent methylation in childhood ALL, methylation status of two of these genes is associated with advanced disease in CML and methylation status of another gene is associated with prognosis. In addition a subset of these genes may act as epigenetic markers across hematological malignancies as well as common epithelial cancers. PMID:20184741



Clinical and haematological characterisation of Mycoplasma suis infections in splenectomised and non-splenectomised pigs.  


Mycoplasma suis causes infectious anaemia in pigs (IAP), which can manifest in various degrees of severity depending on the virulence and the host's susceptibility. As M. suis cannot be cultured in vitro experimental infections of splenectomised animals play an essential role for pathogenesis research. The aim of the present study was to characterise the course of experimental infection using the highly virulent and red blood cell (RBC-) invasive M. suis strain KI3806, to compare the experimental course in splenectomised and non-splenectomised pigs and to correlate clinical and haematological parameters with M. suis blood loads. All infected splenectomised pigs (n=7) were PCR-positive 2 days post infection (DPI) with maximum mean bacterial loads of 1.61 × 10(10)M. suis/mL on 8 DPI. They developed severe anaemia and massive hypoglycaemia by 8 DPI and had to be euthanised preterm (until 8 DPI) without seroconversion. The non-splenectomised pigs (n=7) became PCR-positive within 23 DPI and reached a maximum mean M. suis load of 1.64 × 10(5)M. suis/mL on 8 DPI. They developed mild anaemia, massive skin alterations with petechiae and haemorrhagic diathesis and seroconverted within 35 DPI. The study demonstrated that experimental infection of splenectomised pigs with the highly virulent M. suis strain KI3806 induces a fulminant course of infection. In contrast, M. suis strain KI3806 induces a mild course of disease in non-splenectomised pigs, which resembles the situation in naturally infected pigs. Therefore, these infection models are valuable for future pathogenesis studies on acute and chronic M. suis infections. PMID:24933162

The effects of levamisole poisoning on the haematological and biochemical parameters in dogs.  


This study was designed to evaluate possible organ and system disorders associated with experimentally induced levamisole poisoning in dogs. For this purpose, twelve clinically healthy dogs of different ages, sexes and breeds were used. They were divided into two equal groups (Group A and Group B) and given levamisole orally at a dose of 25 mg/kg of body weight daily for three days. The dogs in Group B were also injected with atropin sulphate (0.04 mg/kg of body weight) subcutaneously (sc) 1 hour after each administration of levamisole. Routine clinical examinations were made and some haematological, biochemical and blood gas parameters were established at various times after administration of levamisole. The dogs in Group A developed severe neurological signs, gastric haemorrhage, bloody vomiting, colic, anaemia and four dogs died. In Group B these signs were mild and only one dog died. Levamisole poisoning was characterised by a significant reduction in the total number of red blood cells (RBCs), concentration of haemoglobin (Hb) and packed cell volume (PCV), and by anaemia. Peripheral blood pH, actual bicarbonate of plasma (HCO3), actual base excess (BE), partial pressure of oxygen (pO2) and saturated oxygen (O2SAT) increased in both groups of animals and these dogs developed metabolic alkalosis 48 hours after the first administration of levamisole. The results of the study also show that levamisole poisoning in dogs causes a significant increase in the activity of serum alanine aminotransferase (ALT) and of alkaline phosphatase (AP) and in the concentration of urea in both Group A and Group B. In the study, atropin sulphate reduced the severity of the clinical signs and the number of deaths, but it was not alone sufficient to remedy levamisole poisoning in dogs. PMID:15032267

Haematological and ion regulatory effects of nitrite in the air-breathing snakehead fish Channa striata.  


The tolerance and effects of nitrite on ion balance and haematology were investigated in the striped snakehead, Channa striata Bloch 1793, which is an air-breathing fish with reduced gills of importance for aquaculture in South East Asia. C. striata was nitrite tolerant with a 96 h LC50 of 4.7 mM. Effects of sub-lethal exposures to nitrite (0mM, 1.4mM, and 3.0mM) were determined during a 7-day exposure period. Plasma nitrite increased, but the internal concentration remained well below ambient levels. Extracellular nitrate rose by several mM, indicating that a large proportion of the nitrite taken up was converted to nitrate. Nitrite reacted with erythrocyte haemoglobin (Hb) causing methaemoglobin (metHb) to increase to 30% and nitrosylhaemoglobin (HbNO) to increase to 10% of total Hb. Both metHb and HbNO stabilised after 4 days, and functional Hb levels accordingly never fell below 60% of total Hb. Haematocrit and total Hb were unaffected by nitrite. Although the effects of nitrite exposure seemed minor in terms of plasma nitrite and metHb increases, ion balance was strongly affected. In the high exposure group, total osmolality decreased from 320 mOsm to 260 mOsm, and plasma sodium from 150 mM to 120 mM, while plasma chloride fell from 105 mM to 60mM and plasma bicarbonate rose from 12 mM in controls to 20mM in exposed fish. The extreme changes in ion balance in C. striata are different from the response reported in other fish, and further studies are needed to investigate the mechanism behind the observed changes in regulation.

A data management software for the Sysmex NE 8000 haematology analyser.  


The Sysmex NE 8000 (TOA-Japan) is a haematology analyser that performs blood cells count and leukocyte differential count. For facilitating the work of technical validation, we developed a software adapted to any IBM or compatible PC running under MS-DOS, to manage the analyser. Data are automatically collected via the RS-232 interface from the analyser or keyed in for the other techniques. The software deals with 64 different analyses entirely "user defined". Six technical alarms of the analyser are taken in account for red or white cells and platelets. An "electronic worksheet" presents the results or alarms with 10 patients to a page. This enables the lab technician to assess the coherence of the various data and to perform verifications or complementary tests if necessary. As an option, a blinking asterisk can signal any results out of predetermined range. By moving the cursor through the table, a test result can be deleted, modified or added. A function displays the patient previous files in a window because the data are recorded in long term archives at the end of the day. This long term recording allows a search of previous files to decide additional tests if the patient is unknown. If the patient is known, with additional tests previously performed, this procedure is time saving. A daily archive function classifies and prints the whole day's work in alphabetical order. A protocol of communication allows a connection to a mainframe computer Bayer-Technicon. This program and the user's manual are free of charge, available on request from J. P. Cambus. PMID:8814394

Effects of sodium butyrate on growth performance, haematological and immunological characteristics of weanling piglets.  


The experiment was conducted to study the effects of sodium butyrate (SB) on growth, haematological and immunological characteristics in weanling pigs. A total of 100 male piglets (Duroc×Landrace×Yorkshire) with a body weight of 8.0 ± 0.2 kg weaned at the age of 28 days were randomly assigned to two treatments with five replicates and 10 pigs per replicate. Piglets received a basal diet (control group) or diets supplemented with 1000 mg/kg SB. The feeding trial lasted for 21 days. The results showed that dietary SB significantly decreased (p < 0.05) diarrhoea incidence of weaned piglets, but did not affect (p > 0.05) the average daily feed intake (ADFI), average daily gain (ADG) and feed to gain (F/G). Furthermore, piglets fed dietary SB had higher (p < 0.05) serum concentrations of glucose and triglycerides and lower (p < 0.05) serum concentrations of urea nitrogen, cortisol, D-lactic acid and diamine oxidase when compared with the control group. However, dietary SB did not affect concentrations of serum albumin, total protein, insulin and glucagon (p > 0.05). There were no significant (p > 0.05) treatment effects on serum IgA and IgM, whereas serum IgG concentration and IgA+ cell count in jejunum from pigs fed SB were significantly higher (p < 0.05) than in those given the basal diet. In conclusion, the present study indicated that dietary SB significantly decreased diarrhoea incidence of weaned piglets and increased the efficiency of nitrogen utilization. Also, dietary SB could regulate and enhance the immune function of piglets by increasing the serum IgG concentration and IgA+ cell count in jejunum. Our results suggest that SB may reduce some of the adverse effects of weaning stress and play an important role in maintaining the integrity of intestinal mucosa. PMID:24024579

Experimental staphylococcal mastitis in bitches: clinical, bacteriological, cytological, haematological and pathological features.  


The objectives of the work were to study the features of experimentally induced canine mastitis and to present hypotheses regarding the pathogenesis of the disease. The right caudal abdominal mammary gland of six bitches was inoculated on day 8 after whelping with Staphylococcus intermedius to induce mastitis; adjacent mammary glands were used as controls. Clinical examination, bacteriological and cytological (whiteside test, Giemsa) examination of mammary secretion, as well as haematological tests were performed from 5 days before until 34 days after challenge. Mastectomy was sequentially performed 1, 2, 4, 18, 26 and 34 days after challenge in each of the bitches, in order to carry out a pathological examination of mammary glands. All animals developed clinical mastitis: challenged glands became painful, hot, enlarged and oedematous; secretion was brownish, purulent, with flakes or clots, subsequently becoming yellowish and thick. Staphylococci were isolated from all inoculated glands (up to 22 days). WST was positive in 41/46 samples from inoculated glands and 66/138 samples from control glands; neutrophils predominated during the acute stage. Blood leukocyte counts increased, whilst platelet counts decreased. Gross pathological findings initially included congestion, purulent discharge and subcutaneous oedema; then abscesses, brownish areas and size decrease were seen. Salient histopathological features were initially neutrophilic infiltration, haemorrhages, destruction of mammary epithelial cells and alveoli, and then infiltration by lymphocytes, shrunken alveoli, loss of glandular architecture and fibrous tissue proliferation. We conclude that in bitches, intrammamary inoculation of Staphylococcus intermedius can induce clinical mastitis, followed by subclinical disease. The disorder is characterized by bacterial isolation and leukocyte influx in challenged glands, by leukocyte presence in adjacent mammary glands, by increased blood leukocyte counts and by destruction of mammary parenchyma.

Algorithm for pre-emptive glycopeptide treatment in patients with haematologic malignancies and an Enterococcus faecium bloodstream infection  

PubMed Central

Introduction Nowadays Enterococcus faecium has become one of the most emerging and challenging nosocomial pathogens. The aim of this study was to determine risk factors in haematology patients who are at risk of an Enterococcus faecium bloodstream infection (BSI) and should be considered for pre-emptive glycopeptide treatment. With these identified risk factors a prediction model can be developed for clinical use. Methods Retrospectively clinical and microbiological data in 33 patients with an E. faecium BSI were compared to 66 control patients during a 5-year period at the haematology ward. Multivariate logistic regression was used to explore the independent risk factors and a prediction model was developed to determine the risk of an E. faecium BSI. Results E. faecium BSIs were found to be associated with high mortality rates. Independent risk factors for E. faecium BSI were colonization with E. faecium 30 days prior to blood culture (OR 5.71; CI 1.7-18.7), combination of neutropenia and abdominal focus (4.37; 1.4-13.4), age?>?58 years (4.01; 1.3-12.5), hospital stay prior to blood culture?>?14 days (3.55; 0.98-12.9) and CRP (C-reactive protein) level >125 mg/L (4.37; 1.1-10.2). Conclusion Using data from this study, risk stratification for the development of an E. faecium BSI in patients with haematological malignancies is possible. Pre-emptive treatment should be considered in those patients who are at high risk. Using a prediction model as designed in this study, antibiotic stewardship in terms of prudent use of glycopeptides can be improved and might be helpful in controlling further spread of VRE (vancomycin resistant enterococci).

Performance evaluation of the Abbott CELL-DYN Ruby and the Sysmex XT-2000i haematology analysers.  


Two mid-range haematology analysers (Abbott CELL-DYN Ruby and Sysmex XT-2000i) were evaluated to determine their analytical performance and workflow efficiency in the haematology laboratory. In total 418 samples were processed for determining equivalence of complete blood count (CBC) measurements, and 100 for reticulocyte comparison. Blood smears served for assessing the agreement of the differential counts. Inter-instrument agreement for most parameters was good although small numbers of discrepancies were observed. Systematic biases were found for mean cell volume, reticulocytes, platelets and mean platelet volume. CELL-DYN Ruby WBC differentials were obtained with all samples while the XT-2000i suppressed differentials partially or completely in 13 samples (3.1%). WBC subpopulation counts were otherwise in good agreement with no major outliers. Following first-pass CBC/differential analysis, 88 (21%) of XT-2000i samples required further analyser processing compared to 18 (4.3%) for the CELL-DYN Ruby. Smear referrals for suspected WBC/nucleated red blood cells and platelet abnormalities were indicated for 106 (25.4%) and 95 (22.7%) of the XT-2000i and CELL-DYN Ruby samples respectively. Flagging efficiencies for both analysers were found to be similar. The Sysmex XT-2000i and Abbott CELL-DYN Ruby analysers have broadly comparable analytical performance, but the CELL-DYN Ruby showed superior first-pass efficiency. PMID:20402823

Protective effects of vitamin C against haematological and biochemical toxicity induced by deltamethrin in male Wistar rats.  


Deltamethrin is a synthetic pyrethroid insecticide. It is known for its wide toxic manifestations. The present experiment pertains to the protective role of vitamin C against haematological and biochemical toxicity induced by deltamethrin during 4 weeks. Male Wistar rats were divided into four groups of eight each: Group I served as control rats; Group II received deltamethrin (1.28 mg/kg BW) in drinking water. Group III received both deltamethrin and vitamin C (200mg/kg BW; by i.p. injection); Group IV received vitamin C (200mg/kg BW). Exposure of rats to deltamethrin caused significant changes of some haematological parameters (red blood cells (RBC), haemoglobin (Hb), haematocrit (Ht), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), mean corpuscular haemoglobin concentration (MCHC), platelet (Plt) and white blood cells (WBC)) in treated rats compared to controls. Significant increases in the levels of hepatic markers enzymes (alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), lactate dehydrogenase (LDH), ?-Glutamyl transpeptidase (?-GT)). Furthermore, renal markers such as urea and creatinine were increased in deltamethrin treated rats. Additionally, serum cholesterol and lipid peroxidation were significantly enhanced. Co-administration of vitamin C to the group III restored all the parameters cited above to near-normal values. Therefore, our investigation revealed that vitamin C appeared to be a promising agent for protection against deltamethrin-induced toxicity. PMID:21514672

Effects of probiotic supplementation over 5 months on routine haematology and clinical chemistry measures in healthy active adults.  


Use of probiotic-containing foods and probiotic supplements is increasing; however, few studies document safety and tolerability in conjunction with defined clinical end points. This paper reports the effects of 150 days of supplementation with either a single- (Bifidobacterium animalis subsp. lactis Bl-04) or a double-strain (Lactobacillus acidophilus NCFM and Bifidobacterium animalis subsp. lactis Bi-07) probiotic on routine haematology and clinical chemistry measures in healthy active adults. Pre- to post-intervention changes in laboratory measures were determined and compared between supplement and placebo groups. Overall there were few differences in routine haematology and clinical chemistry measures between supplement and placebo groups post-intervention. Exceptions included plasma calcium (P=0.03) and urea (P=0.015); however, observed changes were small and within assay-specific laboratory reference ranges. These data provide evidence supporting the use of these probiotic supplements over a period of 5 months in healthy active adults without obvious safety or tolerability issues. PMID:25052229

Physiological adjustments of haematological profile during the last trimester of pregnancy and the early post partum period in mares.  


The aim of the study was to assess changes in some haematological parameters of periparturient mares from the last three months of pregnancy until the third week after foaling. The study was carried out on 15 healthy pregnant mares (Group A) and 7 healthy non-pregnant non-lactating mares (Group B). Blood samples were collected by jugular venipuncture into EDTA tubes and tested for Haematocrit (Hct), Red Blood Cell (RBC), Haemoglobin (Hb), Platelets (Plt) and White Blood Cell (WBC). Peripheral blood smears were also performed to assess changes in the leucocyte differential count. Group A showed a progressive reduction in Hct and Hb levels over the experimental period, whereas Plt and WBC (P<0.05) peaked at parturition. Among WBC, neutrophils increased until parturition when lymphocytes reached the lowest values. The statistical analysis also revealed significant interactions time×pregnancy on Hb (P<0.001), WBC (P<0.001), neutrophils (P<0.001) and lymphocytes (P<0.001). Analysing the last trimester of pregnancy and the first post partum period the present study provides suitable information about the influence of peripartum on mares' haematological parameters.

Endocrine disrupting, haematological and biochemical effects of polybrominated diphenyl ethers in a terrestrial songbird, the European starling (Sturnus vulgaris).  


We exposed female European starlings (Sturnus vulgaris) during a 6month period to environmentally relevant concentrations of a pentabromodiphenyl ether (Penta-BDE) mixture (about 1740?g/kg body weight) through subcutaneous implants, and examined endocrine disruptive, haematological and biochemical effects. To investigate endocrine disrupting effects of PBDEs, testosterone, estradiol and thyroid hormones (T(3) and T(4)) were measured in the plasma. We found no significant differences between the control and exposed groups for any of the hormones. However, 14days after implantation, T(3) concentrations tended to be lower in the exposed group compared to the control group. For albumin, our results suggest that short term exposure of PBDEs may result in a negative effect on albumin, while the opposite was observed on a longer term (6months after implantation). However, from the statistical analysis, effects on albumin disappeared when excluding females that laid eggs. These results demonstrate that observed effects during the breeding season should be interpreted carefully when the breeding status of females is unknown. There were no significant differences found between the control and exposed groups for the other biochemical parameters (total protein, uric acid, cholesterol, aspartate transaminase, total antioxidative capacity, high-density lipoproteins and creatine kinase) and haematological parameters (amount of red blood cells, haemoglobin concentration, haematocrit, mean corpuscular volume and mean corpuscular haemoglobin). All together, our results suggest that European starlings, similar to other passerine species, may be less sensitive to the effects of organohalogenated pollutants, such as PBDEs, than other bird species.

Flow cytometry and thromboelastography to assess platelet counts and coagulation in patients with haematological malignancies  

PubMed Central

Background Accurate platelet counts (PC) are necessary in order to follow recommendations for prophylactic platelet transfusion. We carried out a study comparing the standard way of counting platelets using a routine analyser and compared it with PC determined by flow cytometry (FC) and haemostatic data obtained with thromboelastography (TEG). Materials and methods The study was carried out on 24 patients with haematological malignancies, all given one adult dose of platelets. The PC was determined before and after transfusion using an automated blood cell counter and FC. Citrated, “native” whole blood TEG was carried out before and after platelet transfusion to assess global haemostasis. Results No bleeding was observed in any of the subjects. Thirty-one assessments were performed in the 24 patients. The mean pre-transfusion PC were 9.8 and 13×109/L with the automated counter and FC, respectively with a difference of 3.7 (p=0.0011). Excellent correlation was observed between the two counts (r=0.89; p<0.0001). Mean post-transfusion increments were 23 and 29×109/L for the routine counter and FC, respectively. Using the immunological PC, patients would not have qualified for transfusion in 18.2% of cases since their PC was >20×109/L. TEG showed a shortened reaction time in 69.6% of cases and a normal mean K time of 6.7 min. Only 9% had a low ? angle signifying hypocoagulability. The maximum amplitude was reduced in the majority of cases but normal in 25% despite PC<20×109/L. Mean activated partial thromboplastin time, prothrombin time and fibrinogen were normal prior to transfusion. Discussion Although higher PC as assessed by FC could potentially have an impact on platelet transfusion practices, TEG was sensitive enough to detect PC<10×109/L and some between 10–20×109/L. Whether patients with the latter PC are more prone to bleeding remains to be verified in larger studies. PMID:24960660

Place of death in haematological malignancy: variations by disease sub-type and time from diagnosis to death  

PubMed Central

Background The reasons patients with haematological malignancies die in hospital more often than those with other cancers is the subject of much speculation. We examined variations in place of death by disease sub-type and time from diagnosis to death, to identify groups of ‘at-risk’ patients. Methods The study is based in the United Kingdom within the infrastructure of the Haematological Malignancy Research Network (HMRN), a large on-going population-based cohort including all patients newly diagnosed with haematological malignancies in the north of England. Diagnostic, demographic, prognostic, treatment and outcome data are collected for each patient and individuals are ‘flagged’ for death. This study includes all adults (?18 years) diagnosed 1st September 2004 to 31st August 2010 (n?=?10,325), focussing on those who died on/before 31st August 2012 (n?=?4829). Results Most deaths occurred in hospital (65.9%), followed by home (15.6%), nursing home (11%) and hospice (7.5%) and there was little variation by diagnostic sub-type overall. Differences in place of death were, however, observed by time from diagnosis to death, and this was closely related to sub-type; 87.7% of deaths within a month of diagnosis happened in hospital and these largely occurred in patients with acute myeloid leukaemia, diffuse large B-cell lymphoma and myeloma. Patients surviving longer, and particularly beyond 1 year, were less likely to die in hospital and this corresponded with an increase in the proportion of home deaths. Conclusions Time from diagnosis to death was clearly a major determinant of place of death and many patients that died within three months of diagnosis did so in hospital. This was closely related to disease sub-type, with early deaths occurring most notable in the more aggressive diseases. This is likely to be due to a combination of factors including acute presentation, rapid disease progression without transition to a palliative approach to care and complications of treatment. Nonetheless, hospital deaths also occurred frequently in indolent diseases, suggesting that other factors were likely to contribute to the large proportion of hospital deaths overall. More evidence is needed to fully understand these complex cancers. PMID:24245578



Brand of dipotassium EDTA vacuum tube as a new source of pre-analytical variability in routine haematology testing.  


This study assesses the use of different dry K2 (dipotassium) EDTA vacuum tubes and whether or not they might represent a bias in haematological testing. Blood was collected in three dipotassium EDTA vacuum tubes from different manufacturers: Venosafe, Vacuette and Vacutainer. Samples were analysed on an Advia 2120i analyser. Significant differences among results and biases were compared with current quality specifications. Significant differences were found for haematocrit (HCT), mean corpuscular volume (MCV), white blood cell count (WBC) and platelet distribution width (PDW) when comparing Venosafe vs. Vacuette; for MCV, WBC and PDW when comparing Venosafe vs. Vacutainer; and for HCT and MCV when comparing Vacuette vs. Vacutainer. Clinically significant variations were observed for HCT and PDW in Venosafe vs. Vacuette; PDW in Venosafe vs. Vacutainer; and HCT and MCV in Vacuette vs. Vacutainer. The use of dipotassium EDTA vacuum tubes from different manufacturers represent a clinically relevant source of variation for HCT, MCV and PDW. PMID:23617091

Impact of structured personal on-site patient education on low posaconazole plasma concentrations in patients with haematological malignancies.  


Low posaconazole plasma concentrations (PPCs) are associated with breakthrough invasive mould infections among patients with haematological malignancies. This study evaluated the influence of structured personal on-site patient education on low PPCs. The study was conducted from July 2012 to May 2013 at the Division of Hematology, Medical University Hospital of Graz (Graz, Austria). PPCs were measured in all patients with haematological malignancies receiving the drug prophylactically. Concentrations above the target of 0.5 mg/L were defined as satisfactory and those below this concentration as low. In patients with low PPCs, structured personal on-site education regarding the intake of posaconazole (e.g. intake with fatty/acid food, prevention of nausea and vomiting) was performed. In total, 258 steady-state PPCs were measured in 65 patients [median PPC 0.59 mg/L, interquartile range 0.25-0.92 mg/L; 141/258 (54.7%) satisfactory]. Diarrhoea was the strongest predictor of low PPCs in the multivariate analysis. Initial steady-state PPCs were sufficient in 29 patients and low in 36 patients. Of the 36 patients with low initial steady-state PPCs, 8 were either discharged or antifungal therapy was modified before a follow-up PPC was obtained; in the remaining 28 patients, personal on-site education was performed. In 12/28 patients (43%) the personal on-site education led to sufficient levels, whilst in 16 (57%) PPCs stayed below the target, although increasing from <0.2 mg/L to >0.3 mg/L in 6 of these patients. In conclusion, personal education appears to be a promising tool to increase low PPCs. PMID:25059446

Haematological, serum electrolyte and blood gas effects of small volume hypertonic saline in experimentally induced haemorrhagic shock.  


The effects of treatment with small volume hypertonic (2400 mOsm/litre) and isotonic (300 mOsm/litre) saline on serum electrolyte and biochemical concentrations, haemograms and blood gases were evaluated in 12 horses using a haemorrhagic shock model. Intravascular catheters were placed surgically for sample collection prior to anaesthesia. Controlled haemorrhage was initiated and continued until mean systemic pressure reached 50 to 60 mmHg. Hypertonic or isotonic saline (2 litres) was administered by intravenous infusion and data collected for 2 h. Following haemorrhage, packed cell volume (PCV), haemoglobin, blood glucose concentrations and erythrocyte numbers increased whereas plasma total protein and albumin concentrations decreased. Infusion of hypertonic saline resulted in a further decrease in total protein and albumin concentrations. Glucose concentrations and other haematological variables were unaffected. Isotonic saline administration did not affect electrolyte, total protein or albumin concentrations. Concentrations of sodium and chloride were unaffected by hypotension but increased significantly following hypertonic saline treatment, exceeding normal values during the immediate post treatment period. Serum osmolality increased concurrently. No significant changes in arterial and venous blood gas values were observed with haemorrhage or isotonic saline treatment. A transient decrease in arterial and venous blood pH and a sustained decrease in venous bicarbonate and base excess concentrations occurred following hypertonic saline administration. No significant increases in any serum biochemical concentrations occurred during hypotension or following infusion of either isotonic or hypertonic saline. These results demonstrate that small volume hypertonic saline can be administered safely to horses without producing extreme changes in electrolyte concentrations, blood gases or haematological parameters.

Description of outcomes of experimental infection with feline haemoplasmas: copy numbers, haematology, Coombs' testing and blood glucose concentrations.  


The aim of this study was to compare blood copy, haematological and glucose values between cats experimentally infected with either Mycoplasma haemofelis (Group HF: 10 cats), 'Candidatus M. haemominutum' (Group HM: 3 cats) or 'Candidatus M. turicensis' (Group TU: 3 cats). Blood samples were collected regularly up to 85 days post-infection (DPI) for haemoplasma real-time quantitative PCR, haematology, Coombs' testing and blood glucose measurement. Statistical analysis was performed using a general linear model (ANOVA) appropriate for a repeated measures experiment with significance set as P<0.05. Cats in Group TU had significantly lower blood copy numbers than cats in Group HF (P<0.001) and HM (P<0.001). All Group HF cats developed anaemia (often severe), macrocytosis and evidence of erythrocyte-bound antibodies whereas Groups HM and TU cats did not. Group HF had significantly lower PCVs, haemoglobin concentrations and red blood cell counts, and significantly higher mean cell volumes, than Groups HM and TU. In Group HF, erythrocyte-bound antibodies reactive at 4 degrees C (both IgM and IgG) appeared between 8 and 22 DPI and persisted for two to four weeks, whereas those reactive at 37 degrees C (primarily IgG) appeared between 22 and 29 DPI and persisted for one to five weeks. In most cats antibodies appeared after the fall in haemoglobin started. Although Group TU had significantly lower glucose concentrations than Groups HF (P=0.006) and HM (P=0.027), mean blood glucose concentrations remained within the reference range in all groups. This study demonstrates that M. haemofelis infection, in contrast to 'Candidatus M. haemominutum' and 'Candidatus M. turicensis' infection, can result in a severe macrocytic anaemia and the development of cold and warm reactive erythrocyte-bound antibodies.

The G8 screening tool detects relevant geriatric impairments and predicts survival in elderly patients with a haematological malignancy.  


The G8 screening tool was developed to separate fit older cancer patients who were able to receive standard treatment from those that should undergo a geriatric assessment to guide tailoring of therapy. We set out to determine the discriminative power and prognostic value of the G8 in older patients with a haematological malignancy. Between September 2009 and May 2013, a multi-dimensional geriatric assessment was performed in consecutive patients aged ?67 years diagnosed with blood cancer at the Innsbruck University Hospital. The assessment included (instrumental) activities of daily living, cognition, mood, nutritional status, mobility, polypharmacy and social support. In parallel, the G8 was also administered (cut-off ? 14). Using a cut-off of ?2 impaired domains, 70 % of the 108 included patients were considered as having an impaired geriatric assessment while 61 % had an impaired G8. The G8 lacked discriminative power for impairments on full geriatric assessment: sensitivity 69, specificity 79, positive predictive value 89 and negative predictive value 50 %. However, G8 was an independent predictor of mortality within the first year after inclusion (hazard ratio 3.93; 95 % confidence interval 1.67-9.22, p?haematological malignancies. Although the G8 lacked discriminative power for outcome of multi-dimensional geriatric assessment, this score appears to be a powerful prognosticator and could potentially represent a useful tool in treatment decisions. This novel finding certainly deserves further exploration. PMID:24488257

PubMed Central

The effects of dietary supplementation of selenium (Se), iodine (I), and a combination of both on the blood haematology, serum free thyroxine (FT4) and free triiodothyronine (FT3) hormones and glutathione peroxidase enzyme (GSH-Px) activity were examined on twenty four (7 to 8 months old, 22±1.17 kg live weight) Kacang crossbred male goats. Animals were randomly assigned to four dietary treatments (6 animals in each group). Throughout 100 d of feeding trial, the animals of control group (CON) received a basal diet, while the other three groups were offered basal diet supplemented with 0.6 mg/kg diet DM Se (SS), or 0.6 mg/kg diet DM I (PI), or a combination of both Se and I, each at 0.6 mg/kg diet DM (SSPI). The haematological attributes which are haemoglobin (Hb), red blood cell (RBC), packed cell volume (PCV), mean cell volume (MCV), white blood cells (WBC), band neutrophils (B Neut), segmented neutrophils (S Neut), lymphocytes (Lymph), monocytes (Mono), eosinophils (Eosin) and basophils (Baso) were similar among the four treatment groups, while serum levels of Se and I increased significantly (p<0.05) in the supplemented groups. The combined dietary supplementation of Se and I (SSPI) significantly increased serum FT3 in the supplemented animals. Serum GSH-Px activity increased significantly in the animals of SS and SSPI groups. It is concluded that the dietary supplementation of inorganic Se and I at a level of 0.6 mg/kg DM increased serum Se and I concentration, FT3 hormone and GSH-Px activity of Kacang crossbred male goats.

Growth performance, carcass quality, biochemical and haematological traits and immune response of growing rabbits as affected by different growth promoters.  


The aim of the article was to study the effect of different growth promoters on growth performance, carcass quality, biochemical and haematological traits and immune response of growing rabbits. A total number of 105 male growing NZW rabbits during 35-91 days of age were randomly distributed among 7 groups fed the same basal diet and submitted to different dietary treatments: the first group was unsupplemented and used as control; the other groups were supplemented respectively with bee pollen and/or propolis at 200 mg/kg BW of each and inulin and/or mannanoligosaccharides (MOS) at 35 mg/kg BW of each. Body weight gain, daily feed intake, feed conversion ratio (FCR), biochemical and haematological blood parameters, carcass characteristics, histological studies of ileum and spleen and economical efficiency were measured. Bee pollen administered alone or with propolis significantly (p < 0.01) the body weight gain and improved FCR in respect of the control group. Inulin with MOS significantly improved just FCR than the control group. Bee pollen with propolis and MOS supplemented-groups resulted in significantly higher (7.96 and 8.41% respectively) white blood cells compared to the control group. Plasma total cholesterol was significantly higher for the MOS group in respect of the control, bee pollen, inulin and inulin with MOS supplemented-groups. Propolis resulted in significantly higher dressed carcass percentage than the control group and higher carcass index than only bee pollen with propolis supplemented-group. Bee pollen, in particular if in combination with propolis, could be used as a supplement in the growing rabbits during days 35-91 of age with positive effects on growth rate and feed conversion ratio.

Recommendations of the SFH (French Society of Haematology) for the diagnosis, treatment and follow-up of hairy cell leukaemia.  


Hairy cell leukaemia (HCL) is a rare haematological malignancy, with approximately 175 new incident cases in France. Diagnosis is based on a careful examination of the blood smear and immunophenotyping of the tumour cells, with a panel of four markers being used specifically to screen for hairy cells (CD11c, CD25, CD103 and CD123). In 2011, the V600E mutation of the BRAF gene in exon 15 was identified in HCL; being present in HCL, it is absent in the variant form of HCL (HCL-v) and in splenic red pulp lymphoma (SRPL), two entities related to HCL. The management of patients with HCL has changed in recent years. A poorer response to purine nucleoside analogues (PNAs) is observed in patients with more marked leukocytosis, bulky splenomegaly, an unmutated immunoglobulin variable heavy chain (IgVH) gene profile, use of VH4-34 or with TP53 mutations. We present the recommendations of a group of 11 experts belonging to a number of French hospitals. This group met in November 2013 to examine the criteria for managing patients with HCL. The ideas and proposals of the group are based on a critical analysis of the recommendations already published in the literature and on an analysis of the practices of clinical haematology departments with experience in managing these patients. The first-line treatment uses purine analogues: cladribine or pentostatin. The role of BRAF inhibitors, whether or not combined with MEK inhibitors, is discussed. The panel of French experts proposed recommendations to manage patients with HCL, which can be used in a daily practice. PMID:24994538

Breakthrough candidaemia caused by phenotypically susceptible Candida spp. in patients with haematological malignancies does not correlate with established interpretive breakpoints.  


In a study of 27,864 patients with haematological malignancies, 40 patients with candidaemia were identified, among whom 21 developed candidaemia while receiving systemic antifungal therapy [breakthrough candidaemia (BTC)]. Demographic, clinical, microbiological and molecular features of these episodes were analysed. Compared with 19 patients with de novo candidaemia, patients with BTC were more likely to have neutropenia (81% vs. 63%), longer median duration of neutropenia (27 days vs. 15 days), hypogammaglobulinaemia (62% vs. 37%) and central venous catheters (CVCs) (86% vs. 68%). The median duration of prior antifungal exposure was 46 days (range 3-108 days). Among the 18 available Candida spp. isolates, 15 (83%) were phenotypically susceptible to the antifungal agent that the patient was receiving. Emergence of resistance was the mechanism leading to BTC in three cases of patients receiving echinocandins. Other possible mechanisms of BTC were (i) elevated (?2) minimum lethal concentration/minimum inhibitory concentration (MLC/MIC) ratio (reduced ability for a fungicidal agent to kill a fungal pathogen) in all patients receiving amphotericin B and (ii) elevated MLC/MIC ratios in all Candida parapsilosis isolates with MICs?1 ?g/mL to echinocandins. DNA sequencing of the hotspot 1 region of the fks1 and fks2 genes in seven different isolates of C. parapsilosis group demonstrated P660A in Fks1 but no polymorphisms in fks2. In conclusion, mechanisms for BTC in the setting of prolonged neutropenia may be host-based (hypogammaglobulinaemia and CVC) and pathogen-based. CLSI interpretive breakpoints do not reliably predict BTC in patients with haematological malignancies and warrant further investigation. PMID:25108876

Modulatory effect of N-acetylcysteine on pro-antioxidant status and haematological response in healthy men.  


The aim of this study was to follow up whether the modification of pro-antioxidant status by 8-day oral application of N-acetylcysteine (NAC) in healthy men affects the haematological response, whether there is a direct relationship between antioxidant defences and erythropoietin (EPO) secretion and whether NAC intake enhances exercise performance. Fifteen healthy men were randomly assigned to one of two groups: control or NAC (1,200 mg d(-1) for 8 days prior to and 600 mg on the day of exercise trial). To measure the ergogenic effectiveness of NAC, subjects performed incremental cycle exercise until exhaustion. NAC administration significantly influenced the resting and post-exercise level of glutathione (+31%) as well as the resting activity of glutathione enzymes (glutathione reductase, -22%; glutathione peroxidase, -18%). The oxidative damage markers, i.e., protein carbonylation and lipid peroxidation products (thiobarbituric acid reactive substance) were reduced by NAC by more than 30%. NAC noticeably affected the plasma level of EPO (+26%), haemoglobin (+9%), haematocrit (+9%) and erythrocytes (-6%) at rest and after exercise. The mean corpuscular volume and the mean corpuscular haemoglobin increased by more than 12%. Plasma total thiols increased by 17% and directly correlated with EPO level (r = 0.528, P < 0.05). NAC treatment, contrary to expectations, did not significantly affect exercise performance. Our study has shown that 8-day NAC intake at a daily dose of 1,200 mg favours a pro-antioxidant status and affects haematological indices but does not enhance exercise performance. PMID:20354834

[Investigations on the influence of selected compulsory measures on clinically relevant haematological and blood-chemical parameters of racing pigeons (Columba livia f. dom.)].  


In the presented study the influence of stress and environmental factors on selected haematological and blood-chemical parameters in racing pigeons was examined. Blood was taken at three defined days and haematological as well as blood-chemical parameters of clinical relevance were determined. In comparison to reference values published for pigeons, the majority of the values obtained in this study were within physiological borders. The daily handling of the pigeons did not have any significant effect on the examined parameters. Also the heterophile/lymphocyte ratio did not show any changes characteristic of a stress reaction. In contrast, after change of the housing dies with pigeons originating normally from a flock, the first blood sampling should be performed after a 4 or 5-day lasting period of acclimatisation to the the individual housing conditions.

Comparison of a new device for blood sampling in cats with a vacuum tube collection system - plasma biochemistry, haematology and practical usage assessment.  


Using paediatric devices to collect venous blood from a cephalic vein in cats offers numerous practical advantages over traditional jugular venepuncture and vacuum closed systems: minimal restraint is required; there is minimal risk of serious injury to the cat; the discomfort associated with venepuncture is reduced by the use of small diameter (25 gauge) needles; very small volumes (200 microl) of blood are extracted; and the risk of vein collapse or haematoma is low. The aim of this study was to compare the haematological and plasma chemistry results obtained from six healthy cats using the two sampling techniques. Five plasma biochemical analytes were measured and a complete haematological examination was performed on each specimen. No clinically relevant difference between the two blood sampling techniques was observed for any variable, indicating that paediatric devices provide a useful alternative to vacuum tubes for venous blood collection in the cat.

Prospective observational cohort study of the association between thromboelastometry, coagulation and platelet parameters and bleeding in patients with haematological malignancies- the ATHENA study.  


Previous studies have shown that total platelet count (TPC) inadequately predicts bleeding in thrombocytopenic patients with haematological malignancies. This prospective cohort study evaluated whether rotational thromboelastometry (ROTEM), coagulation or other platelet parameters were more strongly associated with bleeding than TPC. Adults treated at two UK haematology centres for haematological malignancy were enrolled if they had thrombocytopenia (TPC ? 50 × 10(9) /l) at beginning of, or during treatment (International Standard Randomized Controlled Trial Number 81226121). TPC and bleeding symptoms were recorded daily for up to 30 d or until platelet count recovery, hospital discharge or death. Blood samples were tested thrice weekly using ROTEM, Platelet Function Analyser (PFA)-100(®) , coagulation and platelet cytometry assays. Bleeding symptoms and TPC from 49/50 enrolled participants who completed the study were recorded on 754/760 study days. Mean platelet volume and PFA-100(®) closure times were frequently inestimatable because of thrombocytopenia. TPC, absolute immature platelet number (AIPN) and ROTEM maximum clot firmness were significantly associated with bleeding on the day after blood sampling. Only AIPN was associated with bleeding after adjustment of test results for TPC (Odds Ratio 0·52, 95% confidence interval 0·28-0·97; P = 0·038). In a predictive model, AIPN was superior to TPC for predicting bleeding. This study indicates that AIPN may be more clinically useful than TPC at predicting bleeding. PMID:24797282

Time-to-diagnosis and symptoms of myeloma, lymphomas and leukaemias: a report from the Haematological Malignancy Research Network  

PubMed Central

Background Prior to diagnosis, patients with haematological cancers often have multiple primary care consultations, resulting in diagnostic delay. They are less likely to be referred urgently to hospital and often present as emergencies. We examined patient perspectives of time to help-seeking and diagnosis, as well as associated symptoms and experiences. Methods The UK’s Haematological Malignancy Research Network ( routinely collects data on all patients newly diagnosed with myeloma, lymphoma and leukaemia (>2000 annually; population 3.6 million). With clinical agreement, patients are also invited to participate in an on-going survey about the circumstances leading to their diagnosis (presence/absence of symptoms; type of symptom(s) and date(s) of onset; date medical advice first sought (help-seeking); summary of important experiences in the time before diagnosis). From 2004–2011, 8858 patients were approached and 5038 agreed they could be contacted for research purposes; 3329 requested and returned a completed questionnaire. The duration of the total interval (symptom onset to diagnosis), patient interval (symptom onset to help-seeking) and diagnostic interval (help-seeking to diagnosis) was examined by patient characteristics and diagnosis. Type and frequency of symptoms were examined collectively, by diagnosis and compared to UK Referral Guidelines. Results Around one-third of patients were asymptomatic at diagnosis. In those with symptoms, the median patient interval tended to be shorter than the diagnostic interval across most diseases. Intervals varied markedly by diagnosis: acute myeloid leukaemia being 41 days (Interquartile range (IQR) 17–85), diffuse large B-cell lymphoma 98 days (IQR 53–192) and myeloma 163 days (IQR 84–306). Many symptoms corresponded to those cited in UK Referral Guidelines, but some were rarely reported (e.g. pain on drinking alcohol). By contrast others, absent from the guidance, were more frequent (e.g. stomach and bowel problems). Symptoms such as tiredness and pain were common across all diseases, although some specificity was evident by sub-type, such as lymphadenopathy in lymphoma and bleeding and bruising in acute leukaemia. Conclusions Pathways to diagnosis are varied and can be unacceptably prolonged, particularly for myeloma and some lymphomas. More evidence is needed, along with interventions to reduce time-to-diagnosis, such as public education campaigns and GP decision-making aids, as well as refinement of existing Referral Guidelines.

Changes in haematology, plasma biochemistry and erythrocyte osmotic fragility of the Nigerian laughing dove (Streptopelia senegalensis) in captivity.  


The haematology, plasma biochemistry and erythrocyte osmotic fragility of the Nigerian laughing dove (Streptopelia senegalensis) were studied after 4 and 8 weeks in captivity. At 8 weeks, there was a normocytic hypochromic anaemia characterized by reduced values for packed cell volume (PCV), red blood cell count (RBC), haemoglobin (Hb) concentration, mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC), but the mean corpuscular volume (MCV) was unaltered compared with the corresponding values at 4 weeks. The platelet count, total white blood cell count, heterophil, lymphocyte and monocyte counts were also lower at 8 weeks than those of the birds sampled at 4 weeks in captivity. There was also a stress induced increased heterophil/lymphocyte ratio and the erythrocytes were more fragile in hypotonic solution in birds sampled at 8 weeks. Plasma aspartate transaminase (AST), alanine aminotransferase (ALT) and alkaline phosphate (ALP) increased at 8 weeks, though non-significantly, which might have been due to muscle wasting consequent upon decreased muscular activities associated with prolonged captivity. The results suggest that maintaining wild birds in captivity for a prolonged period could be stressful as shown by the heterophil/lymphocytes ratio and reduced erythrocyte osmotic resistance, and could lead to decreases in erythrocyte parameters and muscle wasting.

Haematological parameters as predictors of blood lead and indicators of lead poisoning in the black duck (Anas rubripes).  


The validity of various haematological parameters as indicators of blood lead concentration and lead poisoning in the black duck (Anas rubripes) is discussed. Elevated (> 40 microg dl(-1)) blood lead (PbB) levels were recorded in 41% of the 229 wild birds examined. No correlation was found between PbB concentration and haematocrit. Zinc protoporphyrin (ZPP) was positively correlated with PbB. Haemoglobin, delta-aminolevulinic acid dehydratase (ALA-d) activity and non-activated/activated ALA-d ratios were negatively correlated with PbB. The minimum PbB levels at which these parameters were affected varied greatly. ZPP and haemoglobin were relatively insensitive to PbB concentrations; whilst ALA-d activity and ALA-d ratio were influenced by PbB concentrations of < 5 microg dl(-1). Log(10) ALA-d ratio was more strongly correlated with PbB (r = -0.953) than log(10) ALA-d activity (r = -0.914) and the predictive validity (% false -ve and +ve predictions) of the ratio method was higher. The high individual variability in ALA-d activities at low PbB levels was greatly reduced by the use of the ALA-d ratio method. The ALA-d ratio method proved the most efficient for screening black duck for lead poisoning in the field. PMID:15092391

Effect of Aqueous Stem Bark Extract of Khaya senegalensis on Some Biochemical, Haematological, and Histopathological Parameters of Rats  

PubMed Central

The subchronic effect of aqueous stem bark extract of Khaya senegalensis on some biochemical, haematological, and histopathological parameters of rats was investigated. The rats were divided into six groups of five rats per group. Groups I to VI were administered graded doses of 0, 400, 800, 1200, 1600, and 2000?mg/kg?bw, respectively. The result of study revealed that administration of the Khaya senegalensis for twenty-eight days at the experimental dose resulted in significant (P < 0.05) increase in urea, electrolytes (Na+, K+), and creatinine levels. The extract also significantly (P < 0.05) increased serum activity of ALT, AST, and ALP. The levels of protein, albumin, and bilirubin were significantly changed when compared to their control values, but they were not dose dependent. The hematological indices assayed in this study were not significantly affected at the experimental dose when compared to the control values. Histological studies of the liver showed cellular degeneration and necrosis and bile duct hyperplasia and fibrosis with lymphocytic infiltration of the hepatocyte, providing supportive evidence for discussing the biochemical findings, indicative of functional derangement. The histological architecture of the kidney and that of the heart were however preserved. The result of this study indicates that the aqueous stem bark extract of K. senegalensis may affect the cellular integrity of vital organs of the body. PMID:24348549

Epidemiology and sites of involvement of invasive fungal infections in patients with haematological malignancies: a 20-year autopsy study.  


Autopsy studies remain an essential tool for understanding the patterns of fungal disease not detected ante mortem with current diagnostic approaches. We collected data concerning the microbiological trends, patient clinical characteristics and sites of involvement for invasive fungal infections (IFIs) identified at autopsy in a single large cancer treatment centre over a 20-year period (1989-2008). The autopsy rate and IFI prevalence both declined significantly during the study period. The prevalence of Aspergillus spp. decreased significantly from the first 15 years of the study (from 0.12 to 0.14 cases per 100 autopsies to 0.07 in 2004-2008; P = 0.04), with only Mucorales accounting for a greater proportion of IFIs over the duration of the study period (0.06 to 0.2 cases per 100 autopsies, P = 0.04). After 2003, moulds accounted for the majority of infections identified at autopsy in the spleen, kidney, heart and gastrointestinal tract. Despite a trend of decreasing prevalence from 1989 to 2004, invasive candidiasis increased in prevalence during later periods 2004-2008 (0.02-0.05 per 100 autopsies) with decreasing kidney, heart and spleen involvement. Despite a declining autopsy rate, these data suggest a decreasing prevalence overall of IFIs with changing patterns of dissemination in patients with haematological malignancies. PMID:23551865

Acute effects of aqueous leaf extract of Aspilia africana C.D. Adams on some haematological parameters in rats.  


Several medicinal plants have been documented for their haematological effects either at low or high concentration but very little is known about Aspilia africana. The aim of the study was to investigate the acute effects of aqueous leaf extract of Aspilia africana at different concentrations on some haematological parameters in rats. Following 14 days of oral administration of aqueous extract of A. africana, Haematocrit (HCT), Haemoglobin concentration (HB), Mean Cell Haemoglobin Concentration (MCHC), Red Blood Cell Count (RBC Count), Total White Blood Cell Count (Total WBC Count), Absolute Neutrophils count (NEUT#), Absolute Lymphocytes count (LYM#), Absolute Eosinophils Count (EOSIN#) and Absolute Monocytes (MONO#) were evaluated in twenty (20) male Wistar albino rats. The rats weighed 174 ± 20 g, and were randomly assigned into 4 groups viz: Group 1, Control; Group 2, 250 mg/Kg/d aqueous extract; Group 3, 500 mg/Kg/d aqueous extract; and Group 4, 750 mg/Kg/d aqueous extract. HCT, HB, MCHC, RBC Count, Total WBC Count, NEUT#, LYM#, EOSIN# and MONO# were significantly increased (P<0.001) in 500 mg/Kg/d of A. africana extract (61.13 ± 1.65%, 13.5 ± 1.29 g/dl, 23.33 ± 0.0.02 g/dl, 3.68 ± 0.02 X 10(12)Cells/l, 2.33 ± 0.02 X 10(9)Cells/l, 1.32 ± 0.04 X 10(9)Cells/l, 1.43 ± 0.05 X 10(9)Cells/l, 0.47 ± 0.02 X 10(9)Cells/l and 0.47 ± 0.04 X 10(9)Cells/l, respectively) when compared to the Control (51.13 ± 0.85%, 9.56 ± 0.43 g/dl, 19.22 ± 0.19 g/dl, 2.69 ± 0.01 X 10(12)Cells/l, 1.79 ± 0.01 X 10(9)Cells/l, 0.80 ± 0.00 X 10(9)Cells/l, 0.83 ± 0.00 X 10(9)Cells/l, 0.18 ± 0.00 X 10(9)Cells/l and 0.24 ± 0.00 X 10(9)Cells/l, respectively) which received no extract at all. The 500 mg/Kg of A. africana extract proved to be the most effective, while the 750 mg/Kg proved to be the least effective in comparison with the control. The results of this study further strengthened the earlier works on the medicinal benefits of Aspilia africana and its virtue as a good pharmacological source of haematopoiesis. PMID:24311831

Exogenous Sphingosine-1-Phosphate Boosts Acclimatization in Rats Exposed to Acute Hypobaric Hypoxia: Assessment of Haematological and Metabolic Effects  

PubMed Central

Background The physiological challenges posed by hypobaric hypoxia warrant exploration of pharmacological entities to improve acclimatization to hypoxia. The present study investigates the preclinical efficacy of sphingosine-1-phosphate (S1P) to improve acclimatization to simulated hypobaric hypoxia. Experimental Approach Efficacy of intravenously administered S1P in improving haematological and metabolic acclimatization was evaluated in rats exposed to simulated acute hypobaric hypoxia (7620m for 6 hours) following S1P pre-treatment for three days. Major Findings Altitude exposure of the control rats caused systemic hypoxia, hypocapnia (plausible sign of hyperventilation) and respiratory alkalosis due to suboptimal renal compensation indicated by an overt alkaline pH of the mixed venous blood. This was associated with pronounced energy deficit in the hepatic tissue along with systemic oxidative stress and inflammation. S1P pre-treatment improved blood oxygen-carrying-capacity by increasing haemoglobin, haematocrit, and RBC count, probably as an outcome of hypoxia inducible factor-1? mediated erythropoiesis and renal S1P receptor 1 mediated haemoconcentation. The improved partial pressure of oxygen in the blood could further restore aerobic respiration and increase ATP content in the hepatic tissue of S1P treated animals. S1P could also protect the animals from hypoxia mediated oxidative stress and inflammation. Conclusion The study findings highlight S1P’s merits as a preconditioning agent for improving acclimatization to acute hypobaric hypoxia exposure. The results may have long term clinical application for improving physiological acclimatization of subjects venturing into high altitude for occupational or recreational purposes. PMID:24887065

Proton beam therapy reduces the incidence of acute haematological and gastrointestinal toxicities associated with craniospinal irradiation in pediatric brain tumors.  


Abstract Background. The benefits of proton beam craniospinal irradiation (PrBCSI) in children have been extensively reported in dosimetric studies. However, there is limited clinical evidence supporting the use of PrBCSI. We compared the acute toxicity of PrBCSI relative to that of conventional photon beam CSI (PhBCSI) in children with brain tumours. Material and methods. We prospectively evaluated the haematological and gastrointestinal toxicities in 30 patients who underwent PrBCSI between April 2008 and December 2012. As a reference group, we retrospectively evaluated the medical records of 13 patients who underwent PhBCSI between April 2003 and April 2012. The median follow-up time from starting CSI was 22 months (range 2-118 months). The mean irradiation dose was 32.1 Gy (range 23.4-39.6 Gy) and 29.4 CGE (cobalt grey equivalents; range 19.8-39.6), in the PrBCSI and PhBCSI groups, respectively (p = 0.236). Results. There was no craniospinal fluid space relapse after curative therapy in either group of patients. Thrombocytopenia was less severe in the PrBCSI group than in the PhBCSI group (p = 0.012). The recovery rates of leukocyte and platelet counts measured one month after treatment were significantly greater in the PrBCSI group than in the PhBCSI group (p = 0.003 and p = 0.010, respectively). Diarrhoea was reported by 23% of patients in the PhBCSI group versus none in the PrBCSI group (p = 0.023). Conclusions. The incidence rates of thrombocytopenia and diarrhoea were lower in the PrBCSI group than in the PhBCSI group. One month after completing treatment, the recovery from leukopenia and thrombocytopenia was better in patients treated with PrBCSI than in those treated with PhBCSI. PMID:24913151

Patients with systemic lupus erythematosus and haematological malignancy at a tertiary care centre: timing, histopathology and therapy  

PubMed Central

Objectives Patients with systemic lupus erythematosus (SLE) are at higher risk of haematological malignancies (HMs) than the general population. Most reports have focused on HM diagnosed after SLE, and have excluded concurrent and preceding diagnoses. Information on response to therapy is also limited. Methods We identified 13?296 cases of HM and 10?539 potential patients with SLE at our centre; 45 patients were confirmed to have HM and SLE. Our retrospective case series was based on these 45 patients. Results Of the 45 patients, 64% were diagnosed with HM ?1?year after diagnosis with SLE, and 36% with HM before or concurrent with SLE. Of the 29 patients with HM after SLE, 13 had diffuse large B cell lymphoma (DLBCL), 6 indolent lymphoma, 4 leukaemia, 3 Hodgkin's disease, and 1 each Burkitt's lymphoma, T cell lymphoma and multiple myeloma. Eleven patients with DLBCL were treated with cyclophosphamide, hydroxydaunorubicin, oncovin and prednisone (CHOP) or rituximab-CHOP; hydroxydaunorubicin, oncovin and prednisone; only four achieved durable remission. Of the 16 patients diagnosed with HM before or concurrent with SLE, 9 were diagnosed with HM more than 2?years before SLE and tended to be in remission prior to SLE diagnosis. Seven patients were diagnosed with HM and SLE concurrently; in terms of their HM, six achieved remission or stable disease. Conclusions In summary, DLBCL was the most common type of lymphoma in patients diagnosed with HM after SLE; these patients presented with advanced-stage disease and had poor outcomes. In contrast, patients diagnosed with HM before or concurrent with SLE had early stage disease and typically achieved remission.

Emergence of multidrug resistant acinetobacter blood stream infections in febrile neutropenia patients with haematological cancers and bone marrow failure syndromes.  


Acinetobacter infections are fast emerging as a major nosocomial threat across the globe. With a predilection for blood stream infections in critically ill, immunocompromised patients, their presence is now being felt in febrile neutropenics with underlying malignancies and marrow failure. We aimed through this study to ascertain the current circulating pathogens and levels of antimicrobial resistance in blood stream infections in febrile neutropenia patients, with specific emphasis on elucidating acinetobacter and pseudomonas infections. Clinical and laboratory records of all consecutive neutropenic patients with underlying haematological malignancies and marrow failure, admitted to our AIIMS, New Delhi from April 2009 to March 2010 were analysed for blood stream infections, pathogen profiles and antimicrobial resistance. All clinical and microbiological variables were statistically analysed to elucidate potential risk factors, infection patterns and drug resistance trends. Of the 1,165 blood cultures investigated, 105 episodes of blood stream infections were microbiologically confirmed in febrile neutropenia patients. Gram-negative infections (n = 78, 72.9%) dominated with acinetobacter spp (n = 20, 18.7%) emerging as the most common pathogen. Acinetobacter and pseudomonas together were responsible for 42.9% of all blood stream infections. Both acinetobacter and pseudomonas displayed very high resistance to all five major classes of antibiotics, including multidrug resistance (90.0% and 76.9%) and ESBL production (90.0% and 84.6%), respectively. Comparison of infection patterns and resistance levels with reports over the past decade from this centre and other centres across the globe, revealed a striking increase in multidrug resistant acinetobacter blood stream infections in these patients. Multidrug resistant acinetobacter Infections are a fast emerging threat in febrile neutropenia patients and at this centre in general. Similar early trends from some Indian centres and neighbouring developing countries suggest grave concern. These emerging circulating pathogens and drug resistance patterns demand to systematically evaluate antibiotic and hospital infection policies and to sensitise all clinicians to curb this pathogen capable of rapid nosocomial spread.

Effects of growth hormone on growth performance, haematology, metabolites and hormones in iron-deficient veal calves.  


Effects of subcutaneous (s.c.) administration of 50 micrograms/kg body weight of recombinant bovine growth hormone (rbGH) or saline were studied for 11 weeks in 40 intact male veal calves supplied 50 mg or 10 mg of iron (Fe)/kg of milk replacer (MR). Feed intake, average daily gain and growth: feed ratio were reduced in Fe-deficient calves, but not significantly influenced by rbGH. Plasma Fe and haemoglobin concentration, red-cell number and packed cell volume were decreased in Fe-deficient calves (P < 0.05) and rbGH further reduced red-cell number in Fe-deficient calves (P < 0.05). The age-dependent increase of total Fe binding capacity was greater in Fe-deficient calves and enhanced by rbGH (P < 0.05). Plasma urea concentrations increased, whereas glucose (G) and triiodothyronine (T3) levels decreased in Fe-deficient calves. rbGH significantly increased G in calves fed MR containing 50 mg/kg (P < 0.05) and influenced urea concentrations (P < 0.05). Plasma insulin (I) and IGF-I concentrations were lower in Fe-deficient calves (P < 0.05). Plasma GH in the first hours after rbGH injections increased (P < 0.05) to higher levels in calves fed 10 than in those fed 50 mg Fe/kg MR, but incremental changes were comparable. In conclusion, low Fe intake caused haematologic, metabolic and endocrine changes. Plasma IGF-I, I and T3 concentrations after rbGH administration and effects of rbGH on IGF-I in Fe-deficient calves were reduced, even though plasma GH levels were increased. PMID:7863735

The accuracy of a patient or parent-administered bleeding assessment tool administered in a paediatric haematology clinic.  


Classifying and describing bleeding symptoms is essential in the diagnosis and management of patients with mild bleeding disorders (MBDs). There has been increased interest in the use of bleeding assessment tools (BATs) to more objectively quantify the presence and severity of bleeding symptoms. To date, the administration of BATs has been performed almost exclusively by clinicians; the accuracy of a parent-proxy BAT has not been studied. Our objective was to determine the accuracy of a parent-administered BAT by measuring the level of agreement between parent and clinician responses to the Condensed MCMDM-1VWD Bleeding Questionnaire. Our cross-sectional study included children 0-21 years presenting to a haematology clinic for initial evaluation of a suspected MBD or follow-up evaluation of a previously diagnosed MBD. The parent/caregiver completed a modified version of the BAT; the clinician separately completed the BAT through interview. The mean parent-report bleeding score (BS) was 6.09 (range: -2 to 25); the mean clinician report BS was 4.54 (range: -1 to 17). The mean percentage of agreement across all bleeding symptoms was 78% (mean ? = 0.40; Gwet's AC1 = 0.74). Eighty percent of the population had an abnormal BS (defined as ?2) when rated by parents and 76% had an abnormal score when rated by clinicians (86% agreement, ? = 0.59, Gwet's AC1 = 0.79). While parents tended to over-report bleeding as compared to clinicians, overall, BSs were similar between groups. These results lend support for further study of a modified proxy-report BAT as a clinical and research tool. PMID:25298191

Understanding the impact of pre-analytic variation in haematological and clinical chemistry analytes on the power of association studies  

PubMed Central

Background: Errors, introduced through poor assessment of physical measurement or because of inconsistent or inappropriate standard operating procedures for collecting, processing, storing or analysing haematological and biochemistry analytes, have a negative impact on the power of association studies using the collected data. A dataset from UK Biobank was used to evaluate the impact of pre-analytical variability on the power of association studies. Methods: First, we estimated the proportion of the variance in analyte concentration that may be attributed to delay in processing using variance component analysis. Then, we captured the proportion of heterogeneity between subjects that is due to variability in the rate of degradation of analytes, by fitting a mixed model. Finally, we evaluated the impact of delay in processing on the power of a nested case-control study using a power calculator that we developed and which takes into account uncertainty in outcome and explanatory variables measurements. Results: The results showed that (i) the majority of the analytes investigated in our analysis, were stable over a period of 36?h and (ii) some analytes were unstable and the resulting pre-analytical variation substantially decreased the power of the study, under the settings we investigated. Conclusions: It is important to specify a limited delay in processing for analytes that are very sensitive to delayed assay. If the rate of degradation of an analyte varies between individuals, any delay introduces a bias which increases with increasing delay. If pre-analytical variation occurring due to delays in sample processing is ignored, it affects adversely the power of the studies that use the data. PMID:25085103

Mortality, morbidity, and haematological results from a cohort of long-term workers involved in 1,3-butadiene monomer production.  

PubMed Central

A retrospective mortality analysis and prospective morbidity and haematological analyses were performed for Shell Deer Park Manufacturing Complex (DPMC) male employees who worked in jobs with potential exposure to 1,3-butadiene from 1948 to 1989. 614 employees qualified for the mortality study (1948-89), 438 of those were still employed during the period of the morbidity study (1982-9), and 429 of those had haematological data available for analysis. Industrial hygiene data from 1979 to 1992 showed that most butadiene exposures did not exceed 10 ppm (eight-hour time weighted average (8 hour TWA)), and most were below 1 ppm, with an arithmetic mean of 3.5 ppm. 24 deaths occurred during the mortality study period. For all causes of death, the standardised mortality ratio (SMR) was 48 (95% confidence interval (95% CI) = 31-72), and the all cancer SMR was 34 (95% CI = 9-87). There were only two deaths due to lung cancer (SMR 42, 95% CI = 5-151) and none due to lymphohaematopoietic cancer (expected = 1.2). Morbidity (illness absence) events of six days or more for the 438 butadiene employees were compared with the rest of the complex. No cause of morbidity was in excess for this group; the all cause standardised morbidity ratio (SMbR) was 85 (95% CI = 77-93) and the all neoplasms SMbR was 51 (95% CI = 22-100). Haematological results for the 429 with laboratory data were compared with results for the rest of the complex. No significant differences occurred between the two groups and the distributions of results between butadiene and non-butadiene groups were virtually identical. These results suggest that butadiene exposures at concentrations common at DPMC in the past 10-20 years do not pose a health hazard to employees. PMID:8199682

Serum cortisol and haematological, biochemical and antioxidant enzyme variables in horse blood sampled in a slaughterhouse lairage, immediately before stunning and during exsanguination.  


The aim of the study was to determine changes of serum cortisol and biochemical, haematological and antioxidant enzyme variables in the blood of horses sampled during the pre-slaughter period (in the lairage and in the stunning box) and during exsanguination. A total of 24 Slovenian warm-blooded horses were observed. Blood samples for determination of serum cortisol and biochemical, haematological (red blood cell count, haematocrit, haemaglobin concentration) and antioxidant enzyme (whole blood superoxide dismutase and glutathione peroxidase) variables were collected by venipuncture of the left jugular vein in the lairage pen, 60 min before stunning (lairage) and immediately before stunning (stunning box). At exsanguination, blood samples were collected from the wound at the time of jugular vein sticking. During blood collection in the lairage pen and in the stunning box, horses were gently restrained with a halter. They were stunned using a penetrating captive bolt pistol impelled by air and were bled by jugular vein sticking. Horses were physically active in the lairage pen and in the race before entering the stunning box. After stunning, the horses showed paddling movements with their legs. In horses, the plasma lactate and glucose concentrations, the serum potassium concentration, the activities of the serum muscle enzymes aspartate aminotransferase and creatine kinase, and values of most of the other biochemical (Table 1) and haematological variables (Table 2), were significantly (P < 0.05) higher at exsanguination, than in blood sampled while they were in the lairage and in the stunning box. The serum concentrations of cortisol and chloride and the activities of alanine aminotransferase and antioxidant enzymes were not significantly different between the pre-slaughter period and exsanguination. All selected blood variables were not significantly different between the lairge and the stunning box sampling time, indicating no physiological stress responses of the investigated horses to stressors, such as novelty of the pre-slaughter environment and handling, present in the slaughterhouse between the lairage and the stunning box. However, the significantly higher values, at exsanguination, for the plasma lactate and glucose concentrations, serum muscle enzyme activities and haematological variables, than during the pre-slaughter period, might partially be attributed to stimulation of the sympathetic nervous system, caused by stunning and bleeding.

Facilitating Surveillance of Pulmonary Invasive Mold Diseases in Patients with Haematological Malignancies by Screening Computed Tomography Reports Using Natural Language Processing  

PubMed Central

Purpose Prospective surveillance of invasive mold diseases (IMDs) in haematology patients should be standard of care but is hampered by the absence of a reliable laboratory prompt and the difficulty of manual surveillance. We used a high throughput technology, natural language processing (NLP), to develop a classifier based on machine learning techniques to screen computed tomography (CT) reports supportive for IMDs. Patients and Methods We conducted a retrospective case-control study of CT reports from the clinical encounter and up to 12-weeks after, from a random subset of 79 of 270 case patients with 33 probable/proven IMDs by international definitions, and 68 of 257 uninfected-control patients identified from 3 tertiary haematology centres. The classifier was trained and tested on a reference standard of 449 physician annotated reports including a development subset (n?=?366), from a total of 1880 reports, using 10-fold cross validation, comparing binary and probabilistic predictions to the reference standard to generate sensitivity, specificity and area under the receiver-operating-curve (ROC). Results For the development subset, sensitivity/specificity was 91% (95%CI 86% to 94%)/79% (95%CI 71% to 84%) and ROC area was 0.92 (95%CI 89% to 94%). Of 25 (5.6%) missed notifications, only 4 (0.9%) reports were regarded as clinically significant. Conclusion CT reports are a readily available and timely resource that may be exploited by NLP to facilitate continuous prospective IMD surveillance with translational benefits beyond surveillance alone.

Malathion-induced changes in the haematological profile, the immune response, and the oxidative/antioxidant status of Cyprinus carpio carpio: protective role of propolis.  


The present study investigated the potential ameliorative effects of propolis against malathion toxicity in the blood and various tissues of carp. The fish were exposed to sublethal concentrations of malathion (0.5 and 1 mg/L) for 10 days, and propolis (10 mg/kg of fish weight) was simultaneously administered. Blood and tissue (liver, kidney, and gill) samples were collected at the end of the experiment and analysed to determine the haematological profile (red blood cell count, haemoglobin concentration, haematocrit level, and erythrocyte indices: mean corpuscular volume, mean corpuscular haemoglobin, and mean corpuscular haemoglobin concentration), immune response (white blood cell count, oxidative radical production, nitroblue tetrazolium (NBT) activity, total plasma protein and total immunoglobulin levels, and the phagocytic activity), and oxidant/antioxidant status (malondialdehyde and reduced glutathione levels and superoxide dismutase, catalase, and glutathione peroxidase activities) of the fish. The findings of this study demonstrate that malathion has a negative effect on the haematological parameters, immune response, and antioxidant enzyme activities of the fish. However, the administration of propolis ameliorated the malathion-induced toxic effects. PMID:24480596

Haematological, biochemical and coagulation changes in mice, guinea-pigs and monkeys infected with a mouse-adapted variant of Ebola Zaire virus.  


Ebola Zaire virus from the 1976 outbreak (EBO-Z) was recently adapted to the stage of lethal virulence in BALB/c mice through serial passage. In the present study, various parameters were examined in groups of mice and guinea-pigs and in three rhesus monkeys after infection with mouse-adapted EBO-Z. The virus caused fatal disease not only in mice but also in guinea-pigs, in which the course of illness resembled that produced by guinea-pig-adapted EBO-Z. Mice, guinea-pigs and monkeys showed similar haematological and biochemical disturbances, but coagulopathy was less striking in mice than in the other two species. The virus caused severe illness in all three monkeys, one of which died. In the lethally infected monkey the degree of viraemia and the haematological, serum biochemical and coagulation changes were greater than in the other two animals, an observation that may prove to be of value in predicting fatal outcome. All three monkeys developed disseminated intravascular coagulation. The two survivors were completely resistant to challenge one year later with non-adapted EBO-Z. In general, the clinical and pathological changes produced in the three species resembled those previously described in guinea-pigs and non-human primates infected with non-mouse-adapted EBO-Z. It was noteworthy, however, that mouse-adaptation appeared to have resulted in a degree of attenuation for monkeys. PMID:11798241

Effect of single doses of methoxypolyethylene glycol-epoetin beta (CERA, Mircera™) and epoetin delta (Dynepo™) on isoelectric erythropoietin profiles and haematological parameters.  


Erythropoietin (EPO) has been misused in sports for many years due to its performance-enhancing effect. In the last decade, detection of abuse has been possible with isoelectric focusing (IEF) based on the different isoform profiles of endogenous and recombinant EPO. The release of new EPOs on the market, such as the recombinant erythropoietin epoetin delta (Dynepo™) and the chemically modified EPO, CERA (Mircera™) potentially represents analytical challenges to the fight against doping. This study set out to investigate the possibility of and the time window for detecting the administration of a single dose of Dynepo™ and CERA. Our results are in agreement with earlier findings that detection of Dynepo™ is best achieved by combining IEF with SDS-PAGE. Haematological parameters were monitored for possible effects due to the long half-life (130 hours) of CERA in blood. Interestingly, although several haematological parameters were significantly changed after the injection of CERA, the endogenous EPO signal was still present in all collected samples. Due to the long half-life and the large size of the CERA molecule (about 60 kDa), it was uncertain whether CERA would be excreted into urine in detectable amounts unless urine collection was preceded by strenuous physical exercise. We find that CERA can be detected in urine without prior exercise in several, but not all, subjects. CERA is nevertheless best detected in serum with regard to both probability and length of detection, in addition to stability in matrix over time. PMID:21387570

Hand-held dynamometry in patients with haematological malignancies: Measurement error in the clinical assessment of knee extension strength  

PubMed Central

Background Hand-held dynamometry is a portable and inexpensive method to quantify muscle strength. To determine if muscle strength has changed, an examiner must know what part of the difference between a patient's pre-treatment and post-treatment measurements is attributable to real change, and what part is due to measurement error. This study aimed to determine the relative and absolute reliability of intra and inter-observer strength measurements with a hand-held dynamometer (HHD). Methods Two observers performed maximum voluntary peak torque measurements (MVPT) for isometric knee extension in 24 patients with haematological malignancies. For each patient, the measurements were carried out on the same day. The main outcome measures were the intraclass correlation coefficient (ICC ± 95%CI), the standard error of measurement (SEM), the smallest detectable difference (SDD), the relative values as % of the grand mean of the SEM and SDD, and the limits of agreement for the intra- and inter-observer '3 repetition average' and the 'highest value of 3 MVPT' knee extension strength measures. Results The intra-observer ICCs were 0.94 for the average of 3 MVPT (95%CI: 0.86–0.97) and 0.86 for the highest value of 3 MVPT (95%CI: 0.71–0.94). The ICCs for the inter-observer measurements were 0.89 for the average of 3 MVPT (95%CI: 0.75–0.95) and 0.77 for the highest value of 3 MVPT (95%CI: 0.54–0.90). The SEMs for the intra-observer measurements were 6.22 Nm (3.98% of the grand mean (GM) and 9.83 Nm (5.88% of GM). For the inter-observer measurements, the SEMs were 9.65 Nm (6.65% of GM) and 11.41 Nm (6.73% of GM). The SDDs for the generated parameters varied from 17.23 Nm (11.04% of GM) to 27.26 Nm (17.09% of GM) for intra-observer measurements, and 26.76 Nm (16.77% of GM) to 31.62 Nm (18.66% of GM) for inter-observer measurements, with similar results for the limits of agreement. Conclusion The results indicate that there is acceptable relative reliability for evaluating knee strength with a HHD, while the measurement error observed was modest. The HHD may be useful in detecting changes in knee extension strength at the individual patient level. PMID:19272149

White Blood Cell Count in Women: Relation to Inflammatory Biomarkers, Haematological Profiles, Visceral Adiposity, and Other Cardiovascular Risk Factors  

PubMed Central

The role of white blood cell (WBC) count in pathogenesis of diabetes, cardiovascular disease, and obesity-related disorders has been reported earlier. Recent studies revealed that higher WBC contributes to atherosclerotic progression and impaired fasting glucose. However, it is unknown whether variations in WBC and haematologic profiles can occur in healthy obese individuals. The aim of this study is to further evaluate the influence of obesity on WBC count, inflammatory biomarkers, and metabolic risk factors in healthy women to establish a relationship among variables analyzed. The sample of the present study consisted of 84 healthy women with mean age of 35.56±6.83 years. They were categorized into two groups based on their body mass index (BMI): obese group with BMI >30 kg/m2 and non-obese group with BMI <30 kg/m2. We evaluated the relationship between WBC and platelet count (PLT) with serum interleukin 6 (IL-6), C-reactive protein (CRP), angiotensin ? (Ang ?), body fat percentage (BF %), waist-circumference (WC), and lipid profile. WBC, PLT, CRP, and IL-6 in obese subjects were significantly higher than in non-obese subjects (p< 0.05). The mean WBC count in obese subjects was 6.4±0.3 (×109/L) compared to 4.4±0.3 (×109/L) in non-obese subjects (p=0.035). WBC correlated with BF% (r=0.31, p=0.004), CRP (r=0.25, P=0.03), WC (r=0.22, p=0.04), angiotensin ? (r=0.24, p=0.03), triglyceride (r=0.24, p=0.03), and atherogenic index of plasma (AIP) levels (r=0.3, p=0.028) but not with IL-6. Platelet count was also associated with WC and waist-to-hip ratio (p<0.05). Haemoglobin and haematocrit were in consistent relationship with LDL-cholesterol (p<0.05). In conclusion, obesity was associated with higher WBC count and inflammatory parameters. There was also a positive relationship between WBC count and several inflammatory and metabolic risk factors in healthy women. PMID:23617205

Effect of feeding cassava (Manihot esculenta Crantz) root meal on growth performance, hydrocyanide intake and haematological parameters of broiler chicks.  


The effect of feeding cassava root meal on growth performance, hydrocyanide intake, haematological indices and serum thiocyanate concentration of broiler chicks was investigated using 300-day-old male broilers. There were five dietary treatments arranged in a 2?×?2?+?1 factorial arrangement of two processing methods of cassava root (peeled and unpeeled) included at two levels (100 and 200 g/kg) plus a control diet (maize-based diet, containing no cassava root). Each treatment was replicated six times with ten birds per replicate. The feeding trial lasted for 28 days. Control-fed birds had the highest overall (P?

Anticancer Effect of dl-Glyceraldehyde and 2-Deoxyglucose in Ehrlich Ascites Carcinoma Bearing Mice and Their Effect on Liver, Kidney and Haematological Parameters.  


Cancer cells generally exhibit increased glycolysis for ATP generation (the Warburg effect). Compounds that inhibit glycolysis have potential applications in cancer treatment. dl-glyceraldehyde (DLG) and 2-Deoxyglucose (2-DG) have been proven effective in the inhibition of glucose metabolism. Ehrlich ascites carcinoma (EAC) cells were injected intraperitoneally (i.p) in 10-12 weeks old Swiss albino mice, weighing between 20 and 30 g. The anticancer activity of DLG and 2-DG were determined by tumor volume, tumor weight, viable and nonviable tumor cell count, average survival time, percentage increase in life span and tumor inhibition ratio. The blood samples were obtained for biochemical analysis after 9 days of treatment to study the effect on liver, kidney and haematological parameters. Histopathological examination of liver and kidney was also performed. One-way ANOVA test and Dunnett's test were used for comparisons of parameters in study groups. Both DLG and 2-DG individually decreased the tumor weight, tumor volume, viable tumor cell count and significantly increased the life span of treated mice, however the combination was found to be better. The biochemical parameters of liver and kidney functions and haematological parameters were restored close to control group as compared with the EAC bearing mice. Histopathological examination of liver and kidney in EAC control group showed large areas of necrosis, congestion and mononuclear cell infiltration but such changes were not observed in liver and kidney sections observed after i.p injection of DLG and 2-DG for 9 days. Improvement was much better in the group where combination of these two drugs were used. PMID:24757305

Changes in haematology measurements with the Sysmex XT-2000iV during storage of feline blood sampled in EDTA or EDTA plus CTAD.  


In veterinary medicine a complete blood cell count (CBC) cannot always be performed within 24 h as usually recommended, particularly for specimens shipped to a reference laboratory. This raises the question of the stability of the variables, especially in ethylenediamine tetra-acetic acid (EDTA) feline blood specimens, known to be prone to in vitro platelet aggregation. Citrate, theophylline, adenosine and dipyridamole (CTAD) has been reported to limit platelet aggregation in feline blood specimens. The aim of this study was to measure the stability of the haematological variables and the platelet aggregation score in EDTA and EDTA plus CTAD (EDCT) feline blood specimens during 48 h of storage at room temperature. Forty-six feline EDTA and EDCT blood specimens were analysed with a Sysmex XT-2000iV analyser, and the platelet count and score of platelet aggregation were estimated immediately and after 24 and 48 h of storage. A significant increase in mean corpuscular volume, haematocrit, reticulocyte and eosinophil counts, and a significant decrease in mean corpuscular haemoglobin concentration and monocyte count were observed. Haemoglobin, mean corpuscular haemoglobin, and red blood cell, white blood cell, neutrophil and lymphocyte counts remained stable. Changes in reticulocyte indexes with time (low fluorescence ratio, medium fluorescence ratio, high fluorescence ratio and immature reticulocyte fraction) were not significant. Changes were generally more pronounced in EDTA than in EDCT. Platelet aggregation decreased markedly in initially highly aggregated EDTA specimens, and increased slightly in initially non- or mildly-aggregated EDTA or EDCT specimens. Platelet counts increased and decreased, or remained stable, respectively. CTAD can reduce storage-induced changes of the haematological variables in feline samples, thus improving the reliability of a CBC and limiting clinical misinterpretations. PMID:23264612

Association of interferon regulatory factor 4 gene polymorphisms rs12203592 and rs872071 with skin cancer and haematological malignancies susceptibility: a meta-analysis of 19 case-control studies  

PubMed Central

Background Research has indicated that the rs12203592 and rs872071 interferon regulatory factor 4 (IRF4) gene polymorphisms correlate with the risk of cancer, especially skin cancer and haematological malignancies, but the results remain controversial. To understand better the effects of these two polymorphisms on skin cancer and haematological malignancies susceptibility, a cumulative meta-analysis was performed. Methods We conducted a search using the PubMed and Web of Science databases for relevant case-control studies published before April 2014. Summary odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were estimated using fixed- or random-effects models where appropriate. Heterogeneity test, publication bias test, and sensitivity analysis were also performed. Results In total, 11 articles comprised of 19 case–control studies were identified; five focused on the rs12203592 polymorphism with 7,992 cases and 8,849 controls, and six were on the rs872071 polymorphism with 3108 cases and 8300 controls. As for rs12203592, a significant correlation with overall skin cancer and haematological malignancies risk was found with the homozygote comparison model (OR?=?1.566, 95% CI 1.087-2.256) and recessive model (OR?=?1.526, 95% CI 1.107-2.104). For rs872071, a significantly elevated haematological malignancies risk was observed in all genetic models (homozygote comparison: OR?=?1.805, 95% CI 1.402-2.323; heterozygote comparison: OR?=?1.427, 95% CI 1.203-1.692; dominant: OR?=?1.556, 95% CI 1.281-1.891; recessive: OR?=?1.432, 95% CI 1.293-1.587; additive: OR?=?1.349, 95% CI 1.201-1.515). Similarly, increased skin cancer and haematological malignancies risk was also identified after stratification of the SNP data by cancer type, ethnicity and source of controls for both polymorphisms. Conclusions Our meta-analysis indicated that the rs12203592 and rs872071 IRF4 gene polymorphisms are associated with individual susceptibility to skin cancer and haematological malignancies. Moreover, the effect of the rs12203592 polymorphism on skin cancer risk was particularly prominent among Caucasians. Further functional research should be performed to validate the association.

A study of haematological and bone marrow changes in symptomatic patients with human immune deficiency virus infection with special mention of functional iron deficiency, anaemia of critically ill and haemophagocytic lymphohistiocytosis  

PubMed Central

Background Haematological abnormalities are among the most common complications of HIV. These involve all lineages of blood cells. Bone marrow studies form integral part of complete workup of the HIV positive patients specially when they present as case of pyrexia of unknown origin (PUO), refractory anaemia and pancytopenia. Method 55 HIV infected symptomatic patient requiring bone marrow examination were included in the study. Relevant clinical history, baseline haematological investigations including full blood count, CD4 cell counts using flow cytometry were recorded. Results Median ANC values in males were found to be significantly lower than females (p = 0.046). CD4 cell count statistically significantly correlated with age, TLC, ANC & platelet count. Anaemia was present in 45 patients and out of which 66.66% patients had normocytic normochromic anaemia. Iron deficiency anaemia was present in (37.77%) patients and anaemia of chronic disease in (62.22%) patients. 2 patients had anaemia of the critically ill. Two patients had non-Hodgkin's lymphoma (NHL) and showed lymphoma deposit in the bone marrow. Gelatinous degeneration was seen in 3 patients. Ill formed epithelioid cell granulomas were seen in 7 cases, and 2 cases were positive for acid fast bacilli (AFB). Haemophagocytosis was seen in 8 cases; two cases later diagnosed as a case of infection induced HLH. Leishmania donovani (LD) bodies seen in 2 cases. Conclusions Bone marrow study is an important investigation in HIV infected symptomatic patients with peripheral haematological abnormalities. PMID:24600136

Immuno-haematologic and virologic responses and predictors of virologic failure in HIV-1 infected adults on first-line antiretroviral therapy in Cameroon  

PubMed Central

Background Contemporary data on the immunologic, haematologic and virologic responses and predictors of virologic failure after initiation of free antiretroviral treatment in Cameroon are needed to evaluate the current treatment-monitoring algorithm and to complement efforts to scale-up and improve on the management of HIV infections. Methods This was a cross-sectional study conducted between October 2010 and June 2012. A total of 951 participants aged 18–74 years were recruited from selected approved HIV treatment centres of the Northwest and Southwest regions. This comprised 247 males and 704 females. Demographic, self-reported risk behaviours and socioeconomic data were obtained using a structured questionnaire. Full blood and CD4?+?T-cell counts were done using standard automated techniques. Determination of viral load (VL) was done using Abbott RealTime HIV-1?m2000™ system. Data was analysed using SPSS version 17. The statistical significance level was P??500 cells/?L respectively. Anaemia was present in 26.2% of the participants with 62.3%, 25.7% and 12% described as mild, moderate and severe anaemia respectively. Virologic failure occurred in 23.2% of the participants with 12.3% having VL?>?10,000 RNA copies/mL. Meanwhile 76.8% of patients attained adequate viral suppression with 40.8% having undetectable viral load. The age group 18–29 years (p?=?0.024), co-infection with tuberculosis (p?=?0.014), anaemia (p?=?0.028) and distance from the treatment centre (p?=?0.011) independently predicted virologic failure. Conclusion The majority of the participants achieved adequate viral suppression after???6 months of ART. Despite these favourable immuno-haematologic and virologic outcomes, the National AIDS Control Program should step-up efforts to improve on antiretroviral drug distribution, as well as proper assessment and management of anaemia, foster early diagnosis and treatment of tuberculosis and enhance treatment adherence counselling especially in younger patients.

Clinical utility of Aspergillus galactomannan and PCR in bronchoalveolar lavage fluid for the diagnosis of invasive pulmonary aspergillosis in patients with haematological malignancies.  


Interpretation of Aspergillus galactomannan (GM) and PCR results in bronchoalveolar lavage (BAL) fluid for the diagnosis of invasive pulmonary aspergillosis (IPA) in patients with haematological malignancies requires clarification. A total of 116 patients underwent BAL for investigation of new lung infiltrates: 40% were neutropenic, 68% and 36% were receiving mould-active antifungal agents and ?-lactam antibiotics. The diagnosis of proven IPA (n = 3), probable IPA (n = 15), and possible invasive fungal disease (IFD, n = 50) was made without inclusion of GM results. BAL GM (at cut-off of 0.8) had lower diagnostic sensitivity for IPA than PCR (61% versus 78%) but higher specificity (93% versus 79%). Both tests had excellent negative predictive values (85-90%), supporting their utility in excluding IPA. The use of BAL GM and PCR results increased the certainty of Aspergillus aetiology in 7 probable IPA cases where fungal hyphae were detected in respiratory samples by microscopy, and upgraded 24 patients from possible IFD to probable IPA. Use of BAL GM and PCR improves the diagnosis of IPA. PMID:24768294

The effects of inulin supplementation of diets with or without hydrolysed protein sources on digestibility, faecal characteristics, haematology and immunoglobulins in dogs.  


Dogs with food allergy are often treated by giving a diet with hydrolysed protein sources. Prebiotics might also be successful in prevention and treatment of allergic disease through their effect on the colonic microflora, analogous to studies on probiotics in allergic children. The present study was set up to investigate the effect of supplementing inulin (IN) to commercial hypoallergenic dog diets on apparent nutrient digestibility, faecal characteristics, haematology and Ig in dogs. Supplementation of 3 % IN did not affect faecal pH, food and water intake and urine production. Compared with the intact protein diet with a limited number of ingredients (L), the diet with a hydrolysed protein source (H) resulted in an increased water intake (P<0.001), which could be due to the osmotic effect of free amino acids. Faeces production was increased by IN due to increased faecal moisture content. Increased faeces production on the H diet was mainly due to a higher DM excretion. Subsequently, the apparent digestibility coefficient (ADC) of DM was lower in the H diet group. A similar result was noted for ADC of diethyl ether extract and crude ash. The ADC of crude protein was higher in the H diet group, whereas IN decreased the ADC of crude protein. Differences in the ADC of crude protein among the different diets disappeared after correction for a higher faecal biomass, except for the dogs fed the L+IN diet. Total faecal IgA concentrations were lower in the H group (P<0.05) because of lower antigenic stimulation of hydrolysed protein, which implies that hydrolysed protein is really hypoallergenic. The present study indicates that the use of hydrolysed protein diets for canine food allergy treatment can affect digestibility and that combination with IN affected apparent protein digestibility but not IgA response.

Detection of the effects of repeated dose combined propoxur and heavy metal exposure by measurement of certain toxicological, haematological and immune function parameters in rats.  


In the present study, an immunotoxicity test system, containing general toxicological (body weight gain, organ weights), haematological (WBC,RBC, Ht, mean cell volume of the RBCs, cell content of the femoral bone marrow), and immune function (PFC assay, DTH reaction) investigations, was used for detection the effects of a 4 weeks repeated low dose combined oral exposure of male Wistar rats with propoxur and the heavy metals arsenic or mercury. Two doses of the compounds were used: a higher one (the lowest dose which resulted in significant change of at least one parameter examined in previous dose-effect experiments), and a lower one (the highest dose which proved to be non-effective). The applied doses were: 8.51 and 0.851 mg kg(-1) of propoxur, 13.3 and 3.33 mg kg(-1) of NaAsO(2), and 3.20 and 0.40 mg kg(-1) of HgCl(2). In the combination treatment, the high dose of propoxur was combined with the low dose of arsenic or mercury, and the high doses of each heavy metals were combined with the low dose of propoxur. The main finding of this study was that some of the combinations significantly altered the relative weight of liver, adrenals and kidneys, related to both the untreated and the high dose internal control. Among the immune functions examined, only the PFC content of the spleen showed a trend of changes in certain combinations versus the corresponding high dose control. According to the present results, combined exposure with propoxur and the heavy metals examined can modify the detection limit of the single compounds and/or may alter their toxic effects.

Looking for prognosticators in ovine anaplasmosis: discriminant analysis of clinical and haematological parameters in lambs belonging to differently susceptible breeds experimentally infected with Anaplasma ovis  

PubMed Central

Background A study was carried out to evaluate the response of different native sheep breeds to experimental infection with Anaplasma ovis, the most prevalent sheep tick-borne pathogen in Apulia (Southern Italy). Thirty-four lambs belonging to a Northern European breed (Suffolk) and two Southern Italian breeds (Comisana and Altamurana) were infected. Eleven clinical as well as haematological parameters were monitored at different temporal resolutions on the same subjects before and after the infection, resulting in a data set of 435 observations. The present work, aiming to further the research, presents the results of a multivariate analysis carried out to identify which parameters out of the eleven considered are the most reliable parameters to be considered as markers of the disease phenotype as well as prognosticators of practical clinical importance. Results Data were analysed by discriminant analysis. Out of the eleven considered variables (red blood cells, packed cell volume, mean corpuscular volume, mean corpuscular haemoglobin, mean corpuscular haemoglobin content, haemoglobin concentration, white blood cells, neutrophils, leukocytes, platelets, rectal temperature), only seven were included in the step-wise model since significantly increasing the Mahlanobis distance between the two closest groups. Both discriminant functions resulted to be highly significant (P?



Variable presence of KITD816V in clonal haematological non-mast cell lineage diseases associated with systemic mastocytosis (SM-AHNMD).  


In a substantial number of patients with systemic mastocytosis (SM), an associated clonal haematological non-mast cell lineage disease (AHNMD) is detectable. Although most of these patients display KIT mutations, especially KIT(D816V), little is known about their exact frequency and their distribution in AHNMD subtypes. We examined 48 patients with SM-AHNMD for the presence of mutant KIT in the SM and AHNMD components of the disease. Mast cells and AHNMD cells were obtained from immunostained bone marrow sections by laser microdissection and examined by melting point analysis of nested-PCR products. KIT(D816V) was found in AHNMD cells in the vast majority of patients with SM-chronic myelomonocytic leukaemia (CMML, 89%). Unexpectedly, KIT(D816V) was far less frequently detectable in AHNMD cells in patients with SM-myeloproliferative neoplasm (MPN, 20%) and SM-acute myeloid leukaemia (AML, 30%). None of the patients with lymphoproliferative AHNMDs displayed KIT codon 816 mutations in AHNMD cells (0/8). In FIP1L1/PDGFRA-positive chronic eosinophilic leukaemia (CEL), neither the SM nor the CEL component of the disease exhibited the KIT mutation. Our findings demonstrate that KIT codon 816 mutations are variably present in AHNMD cells in patients with SM-AHNMD, depending on the subtype of AHNMD. The high frequency of KIT(D816V) in neoplastic mast cells and leukaemic myelomonocytic cells in SM-CMML may point to a common precursor in these patients, and may have implications for the biology of the disease and the development of KIT-targeting therapies.

Protective effect of herbal and probiotics enriched diet on haematological and immunity status of Oplegnathus fasciatus (Temminck & Schlegel) against Edwardsiella tarda.  


This study determines the effect of diet enriched with the herb Baical skullcap Scutellaria baicalensis, and/or probiotics Lactobacillus sakei BK19 in rock bream, Oplegnathus fasciatus (32 ± 3 g) against Edwardsiella tarda. The changes in haematological parameters, innate immune response, and disease resistance were investigated after 1, 3, and 6 weeks. The white blood cell count (WBC: 10(4) mm(-3)), red blood cell count (RBC: 10(6) mm(-3)), and haemoglobin (Hb: g dl(-1)) levels significant increased (P < 0.05) with mixed diet on 3rd and 6th week and probiotics enriched diet on 6th week. The haematocrit (Ht: %) level significantly increased (P < 0.05) when fed with mixed diet on weeks 1-6. Interestingly, in mixed diet group the lymphocytes (LYM), monocytes (MON), and neutrophils (NEU) significantly increased from week 1-6. The eosinophils (EOS) significantly increased in all the treated groups. In the probiotics or mixed diet groups the total protein (TP: g dl(-1)) increased significantly on weeks 3 and 6. The serum lysozyme activity significantly was enhanced in all the treated groups indicating an increase in the innate immunity level. Serum complement, antiprotease activities, reactive oxygen species (ROS) and reactive nitrogen species (RNS) production significantly increased from week 1-6 with mixed diet. The maximum protection against E. tarda was recorded in mixed diet group with a minimum cumulative mortality of 20% and a high relative percent survival (RPS) of 72.84. In the probiotics and herbal diet groups the cumulative mortality was 25% and 35% and RPS was 68.63 and 59.42, respectively. This study indicates that administration of probiotics or mixed diets can effectively minimize the mortality and restore the altered hematological parameters and enhancing the innate immunity in O. fasciatus against E. tarda.

Effects of cadmium on some haematological and biochemical characteristics of Oreochromis niloticus (Linnaeus, 1758) dietary supplemented with tomato paste and vitamin E.  


The present study investigates the potential protective effects of tomato paste (9 mg/kg-lycopene) in comparison with vitamin E (50 mg/kg) against the impacts of cadmium (Cd) toxicity (4.64 mg/l: ¼ of 96 h LC50) on fishes Cd exposed for 15 and 30 days. Cd impacts were evaluated in terms of biological, haematological and biochemical characteristics. Cd significantly induced free radicals in serum and liver. The activities of aspartate aminotransferase and alanine aminotransferase in serum were significantly increased due to Cd. Treatment with Cd caused a significant increase in Lipid peroxidation and DNA fragmentation in liver tissue and serum glucose and total lipid. On the other hand, Cd significantly led to decline in serum total protein, blood haemoglobin, red blood cell count, haematocrit value, mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration. Dietary supplementation with vitamin E and/or tomato paste to Cd-exposed fish declined significantly the increased lipid peroxidation and DNA fragmentation in liver tissue and the increased aspartate aminotransferase, alanine aminotransferase, glucose and total lipid in serum to the normal condition. This supplementation also significantly increased the declined serum total protein, blood haemoglobin, red blood cell count, haematocrit value, mean corpuscular volume, mean corpuscular haemoglobin and mean corpuscular haemoglobin concentration to the normal state. Cd impacts and tomato paste/or vitamin E supplementations did not reflected on the condition factor of the fish. These findings demonstrated the beneficial diet supplementation of tomato paste phytonutrients and vitamin E in counteracting the harmful effects of Cd on the characters investigated. PMID:20625929

Haematological and infectious complications associated with the treatment of patients with congenital cardiac disease: consensus definitions from the Multi-Societal Database Committee for Pediatric and Congenital Heart Disease.  


A complication is an event or occurrence that is associated with a disease or a healthcare intervention, is a departure from the desired course of events, and may cause, or be associated with, suboptimal outcome. A complication does not necessarily represent a breech in the standard of care that constitutes medical negligence or medical malpractice. An operative or procedural complication is any complication, regardless of cause, occurring (1) within 30 days after surgery or intervention in or out of the hospital, or (2) after 30 days during the same hospitalization subsequent to the operation or intervention. Operative and procedural complications include both intraoperative/intraprocedural complications and postoperative/postprocedural complications in this time interval.The MultiSocietal Database Committee for Pediatric and Congenital Heart Disease has set forth a comprehensive list of complications associated with the treatment of patients with congenital cardiac disease, related to cardiac, pulmonary, renal, haematological, infectious, neurological, gastrointestinal, and endocrinal systems, as well as those related to the management of anaesthesia and perfusion, and the transplantation of thoracic organs. The objective of this manuscript is to examine the definitions of operative morbidity as they relate specifically to the haematological system and to infectious complications. These specific definitions and terms will be used to track morbidity associated with surgical and transcatheter interventions and other forms of therapy in a common language across many separate databases.The MultiSocietal Database Committee for Pediatric and Congenital Heart Disease has prepared and defined a near-exhaustive list of haematological and infectious complications. Within each subgroup, complications are presented in alphabetical order. Clinicians caring for patients with congenital cardiac disease will be able to use this list for databases, quality improvement initiatives, reporting of complications, and comparing strategies for treatment.

Cost analysis of voriconazole versus liposomal amphotericin B for primary therapy of invasive aspergillosis among patients with haematological disorders in Germany and Spain  

PubMed Central

Background The current healthcare climate demands pharmacoeconomic evaluations for different treatment strategies incorporating drug acquisition costs, costs incurred for hospitalisation, drug administration and preparation, diagnostic and laboratory testing and drug-related adverse events (AEs). Here we evaluate the pharmacoeconomics of voriconazole versus liposomal amphotericin B as first-line therapies for invasive aspergillosis (IA) in patients with haematological malignancy and prolonged neutropenia or who were undergoing haematopoietic stem-cell transplantation in Germany or Spain. Methods A decision analytic model based on a decision tree was constructed to estimate the potential treatment costs of voriconazole versus liposomal amphotericin B. Each model pathway was defined by the probability of an event occurring and the costs of clinical outcomes. Outcome probabilities and cost inputs were derived from the published literature, clinical trials, expert panels and local database costs. In the base case, patients who failed to respond to first-line therapy were assumed to experience a single switch between comparator drugs or the other drug was added as second-line treatment. Base-case evaluation included only drug-management costs and additional hospitalisation costs due to severe AEs associated with first- and second-line therapies. Sensitivity analyses were conducted to assess the robustness of the results. Cost estimates were inflated to 2011 euros (€). Results Based on clinical trial success rates of 52.8% (voriconazole) and 50.0% (liposomal amphotericin B), voriconazole had lower total treatment costs compared with liposomal amphotericin B in both Germany (€12,256 versus €18,133; length of therapy [LOT]?=?10-day intravenous [IV]?+?5-day oral voriconazole and 15-day IV liposomal amphotericin B) and Spain (€8,032 versus €10,516; LOT?=?7-day IV?+?8-day oral voriconazole and 15-day IV liposomal amphotericin B). Assuming the same efficacy (50.0%) in first-line therapy, voriconazole maintained a lower total treatment cost compared with liposomal amphotericin B. Cost savings were primarily due to the lower drug acquisition costs and shorter IV LOT associated with voriconazole. Sensitivity analyses showed that the results were sensitive to drug price, particularly the cost of liposomal amphotericin B. Conclusions Voriconazole is likely to be cost-saving compared with liposomal amphotericin B when used as a first-line treatment for IA in Germany and Spain. PMID:25253630



BiOsimilaRs in the management of anaemia secondary to chemotherapy in HaEmatology and Oncology: results of the ORHEO observational study  

PubMed Central

Background The approval of epoetin biosimilars in the European Union requires extensive scientific evaluation and stringent regulatory procedures, including post-marketing studies. The ORHEO (place of biOsimilaRs in the therapeutic management of anaemia secondary to chemotherapy in HaEmatology and Oncology) study was an observational, longitudinal, multicentre study performed in France to evaluate the efficacy and safety of biosimilar epoetins for the treatment of chemotherapy-induced anaemia (CIA) in the clinical setting. Methods Patients >18 years with CIA (haemoglobin [Hb] <11 g/dL) in association with solid tumours, lymphoma or myeloma and eligible for treatment with an epoetin biosimilar were included in this study. Patient characteristics were recorded at baseline along with anaemia-related information, such as observed and target Hb (as chosen by the treating clinician), brand and dose of epoetin biosimilar prescribed, and details of any other treatments. Patients were then followed-up at 3 and 6 months. The primary endpoint was Hb response (defined as Hb reaching ?10 g/dL, an increase of Hb ?1 g/dL since inclusion visit or reaching physician-defined target Hb, with no blood transfusions in the 3 weeks prior to measurement). Other endpoints included adverse events, achievement of target Hb and associated treatments. Results Overall, 2333 patients >18 years (mean age 66.5 years) with CIA (haemoglobin [Hb] <11 g/dL) in association with solid tumours, lymphoma or myeloma and eligible for biosimilar epoetin treatment were included. 99.9% of patients received epoetin zeta (median dose 30,000 IU/week). Mean baseline Hb was 9.61 g/dL, with 35.6% of patients having moderate anaemia (Hb 8–9.5 g/dL). Hb response was achieved in 81.6% and 86.5% of patients at 3 and 6 months, respectively. Overall mean change in Hb level was 1.52?±?1.61 and 1.72?±?1.61 g/dL at 3 and 6 months, respectively. Transfusion and thromboembolic event rates were 9.4% and 2.4% at 3 months, and 5.8% and 1.5% at 6 months, respectively. Conclusions Epoetin zeta was effective and well tolerated in the management of CIA in patients with solid tumours, lymphoma and myeloma. Trial registration Trial registration number: NCT02140736 (date of registration: 14 May 2014). PMID:25011615



[b][/b]Impact of copper (Cu) at the dose of 50 mg on haematological and biochemical blood parameters in turkeys, and level of Cu accumulation in the selected tissues as a source of information on product safety for consumers.  


Introduction. The current state-of the art points to a positive impact of copper (Cu) supplements on the general health status in poultry. Copper induces beneficial changes in the haematological and biochemical blood parameters. It also displays immunostimulating properties and helps maintain a proper microbiological balance in the digestive tract. Objective. The objective of this study was to investigate the impact of Cu at the dose of 50 mg/kg BW, administered in organic and inorganic form, on the haematological and biochemical blood parameters and level of Cu bioaccumulation in the liver and pectoral muscle. Materials and method. The study was carried out on 45 BUT-9 turkeys which had been were reared for 16 weeks. They were divided into 3 experimental groups: I - the control group; II - fed with CuSO4 at the dose of 50 mg Cu•dm (-3) H2O; III - received a Cu chelate with lysine at the same dose. Results. The administration of Cu at the dose exceeding the nutritional recommendations did not induce beneficial changes in the examined birds. This indicates that it is not necessary to administer Cu doses higher than the recommended levels. The extent of Cu accumulation in the pectoral muscle increased by 40% compared to the control group, whereas in the liver it was higher by 30-35% than in the birds without Cu administration. The level of Cu in tissues does not pose a risk to consumers. Conclusions. The supplementation of Cu at the dose of 50 mg has a negative impact on the level of the analyzed parameters. The results of the presented study indicate that the administered Cu dose exceeds birds' demand for this element. PMID:25292130

Characterization of haematological parameters with bortezomib-melphalan-prednisone versus melphalan-prednisone in newly diagnosed myeloma, with evaluation of long-term outcomes and risk of thromboembolic events with use of erythropoiesis-stimulating agents: analysis of the VISTA trial.  


Although haematological toxicities, such as anaemia, are common in multiple myeloma (MM), no clear consensus exists on the use and impact of erythropoiesis-stimulating agents (ESA) on outcomes in MM. This analysis characterizes haematological toxicities and associated interventions in the phase III VISTA (Velcade(®) as Initial Standard Therapy in Multiple Myeloma: Assessment with Melphalan and Prednisone) study of bortezomib plus melphalan/prednisone (VMP, n?=?344) versus MP (n?=?338) in previously untreated MM patients ineligible for high-dose therapy, and evaluates the impact of ESA use or red-blood-cell (RBC) transfusions on outcomes and thromboembolic risk. Incidence of haematological toxicities was similar with VMP and MP; similar rates of interventions and associated complications (e.g. bleeding, febrile neutropenia) were observed. Two hundred thirty three patients received ESA; 204 had RBC transfusions. Frequency of thromboembolic events was low and not affected by ESA use. Median time-to progression (TTP) was similar between ESA/non-ESA [hazard ratio: 1·03 (95% confidence interval 0·76-1·39); P?=?0·8478] in both arms (VMP: 19·9/not reached; MP: 15·0/17·5?months). Three-year overall survival (OS) rates were similar between ESA/non-ESA in each arm. Patients receiving RBC transfusions had significantly shorter OS (P?haematological toxicity. Concomitant ESA use with VMP/MP in previously untreated MM patients did not adversely affect TTP or OS, or increase thromboembolic risk. However, RBC transfusion was associated with significantly shorter survival. PMID:21375521

Evaluation of growth performance, serum biochemistry and haematological parameters on broiler birds fed with raw and processed samples of Entada scandens, Canavalia gladiata and Canavalia ensiformis seed meal as an alternative protein source.  


The experiment was carried out to investigate the inclusion of underutilised legumes, Entada scandens, Canavalia gladiata and Canavalia ensiformis, seed meal in soybean-based diet in broilers. The utilisation of these wild legumes is limited by the presence of antinutrient compounds. Processing methods like soaking followed by autoclaving in sodium bicarbonate solution in E. scandens and C. gladiata and soaking followed by autoclaving in ash solution in C. ensiformis were adopted. The proximate composition of raw and processed samples of E. scandens, C. gladiata and C. ensiformis were determined. The protein content was enhanced in processed sample of E. scandens (46 %) and C. ensiformis (16 %). This processing method had reduced the maximum number of antinutrients such as tannins (10-100 %), trypsin inhibitor activity (99 %), chymotrypsin inhibitor activity (72-100 %), canavanine (60-62 %), amylase inhibitor activity (73-100 %), saponins (78-92 %), phytic acid (19-40 %) and lectins. Hence, the raw samples at 15 % and processed samples at 15 and 30 % were replaced with soybean protein in commercial broiler diet respectively. Birds fed with 30 % processed samples of E. scandens, C. gladiata and C. ensiformis showed significantly similar results of growth performance, carcass characteristics, organ weight, haematological parameters and serum biochemical parameters (cholesterol, protein, bilirubin, albumin, globulin and liver and kidney function parameters) without any adverse effects after 42 days of supplementation. The proper utilisation of these underutilised legumes may act as an alternative protein ingredient in poultry diets. PMID:23076820

The effect of oyster mushroom ?-1.3/1.6-D-glucan and oxytetracycline antibiotic on biometrical, haematological, biochemical, and immunological indices, and histopathological changes in common carp (Cyprinus carpio L.).  


The aim of the study was to evaluate the effect of micronized ?-1.3/1.6-D-glucan (BG) derived from the oyster mushroom Pleurotus ostreatus Hiratake and tetracycline antibiotic oxytetracycline (OTC) on biometrical, haematological, biochemical, and immunological indices, and histopathological changes in tissues of one- to two-year-old common carp (Cyprinus carpio L.). The fish tested were divided into five experimental groups and one control. Carp in the control group were fed commercial carp feed pellets. Fish in the five experimental groups were fed the same pellets supplemented with either OTC, a combination of OTC and BG, or BG as follows: 75 mg oxytetracycline kg(-1) bw (OTC group), 75 mg oxytetracycline kg(-1) bw and 0.5% ?-glucan (OTC + 0.5% BG group), 75 mg oxytetracycline kg(-1) bw and 2.0% ?-glucan (OTC + 2.0% BG group), 0.5% ?-glucan (0.5% BG group), and 2.0% ?-glucan (2.0% BG group). OTC- and BG-supplemented diets and the control diet were administered to experimental and control carp for 50 days (i.e. samplings 1-3, the exposure period); for the following 14 days, fish were fed only control feed pellets with no OTC or BG supplementation (i.e. sampling 4, the recovery period). Blood and tissue samples were collected both during, and at the end of the study. No significant changes in biometrical indices (i.e. total length, standard length, total weight, hepatosomatic and spleen somatic index, and Fulton's condition factor) were found in experimental carp compared to control in any sampling. In haematological indices, significant changes were found only in sampling 2, in which shifts in PCV (P < 0.01), Hb (P < 0.01), and WBC (P < 0.01), and in the counts of lymphocytes (P < 0.01), monocytes (P < 0.01), and neutrophil granulocytes-segments (P < 0.05) were revealed. As for biochemical profiling, plasma concentrations of glucose, albumins, cholesterol, natrium, and chlorides (all P < 0.01), and total proteins, lactate, phosphorus, and potassium (all P < 0.05) as well as the catalytic activity of ALP (P < 0.05) were altered in common carp. A significant change in induced (opsonizedzymosan particles, OZP) chemiluminescence (P < 0.05) in sampling 3 and no shifts in serum immunoglobulins concentration were found in the immunological analysis. Histopathological examination of skin, gills, liver, spleen, and cranial and caudal kidneys revealed no obvious specific changes in any tissue analysed. The use of ?-glucans in clinically healthy aquaculture remains an issue. Nevertheless, their use in breeding endangered by stress stimuli, infectious disease, or adverse environmental factors is defensible. PMID:24041844

Characteristics of platelet indices, neutrophil-to-lymphocyte ratio and erythrocyte sedimentation rate compared with C reactive protein in patients with cerebral infarction: a retrospective analysis of comparing haematological parameters and C reactive protein  

PubMed Central

Objective Elevation of C reactive protein (CRP) is one of the major acute-phase responses following ischaemic or haemorrhagic stroke. This study aims to investigate the associations between platelet indices, neutrophil-to-lymphocyte ratio (NLR) and erythrocyte sedimentation rate (ESR) compared with CRP in patients with cerebral infarction. Setting The clinical data of patients with cerebral infarction were analysed retrospectively. Participants We analysed, unduplicated, 516 patients with cerebral infarction (mean age 66.2±12.7, male/female=291/225). Outcome measures Mean platelet volume (MPV), MPV to platelet count, NLR and ESR were compared with CRP in patients with cerebral infarction in a single institute through Spearman correlation test. Results There were significant correlations between CRP and MPV (?=0.088, p=0.045), NLR (?=0.4, p<0.001) and ESR (?=0.468, p<0.001) in patients with cerebral infarction. In the male group, NLR (?=0.398, p<0.001) and ESR (?=0.502, p<0.001) showed significant correlations with CRP. In the female group, CRP showed significant correlations with MPV (?=0.17, p=0.011), NLR (?=0.392, p<0.001) and ESR (?=0.475, p<0.001). Conclusions MPV, NLR and ESR showed significant correlation with CRP in patients with cerebral infarction. MPV and NLR are cost-effective and simple parameters that can be attainable by using an automatic haematology analyser. Further well-designed and large-scale prospective studies are warranted to evaluate platelet indices or NLR for monitoring patients with cerebral infarction. PMID:25412865

Biosimilar agents in oncology/haematology: from approval to practice  

PubMed Central

The regulation of biosimilars is a process that is still developing. In Europe, guidance regarding the approval and use of biosimilars has evolved with the products under consideration. It is now more than 3 years since the first biosimilar agents in oncology support, erythropoiesis-stimulating agents, were approved in the EU. More recently, biosimilar granulocyte colony-stimulating factors have received marketing approval in Europe. This review considers general issues surrounding the introduction of biosimilars and highlights current specific issues pertinent to their use in clinical practice in oncology. Information on marketing approval, extrapolation, labelling, substitution, immunogenicity and traceability of each biosimilar product is important, especially in oncology where patients are treated in repeated therapy courses, often with complicated protocols, and where biosimilars are not used as a unique therapy for replacement of e.g. growth hormone or insulin. While future developments in the regulation of biosimilars will need to address multiple issues, in the interim physicians should remain aware of the inherent differences between biosimilar and innovator products.

Cyclic nucleotide phosphodiesterases as targets for treatment of haematological malignancies  

PubMed Central

The cAMP signalling pathway has emerged as a key regulator of haematopoietic cell proliferation, differentiation and apoptosis. In parallel, general understanding of the biology of cyclic nucleotide PDEs (phosphodiesterases) has advanced considerably, revealing the remarkable complexity of this enzyme system that regulates the amplitude, kinetics and location of intracellular cAMP-mediated signalling. The development of therapeutic inhibitors of specific PDE gene families has resulted in a growing appreciation of the potential therapeutic application of PDE inhibitors to the treatment of immune-mediated illnesses and haematopoietic malignancies. This review summarizes the expression and function of PDEs in normal haematopoietic cells and the evidence that family-specific inhibitors will be therapeutically useful in myeloid and lymphoid malignancies.

Haematological responses of acute nitrite exposure in walleye (Sander vitreus).  


Nitrite (NO2-) is a toxic intermediary of the bacterial oxidation of nitrogenous wastes (e.g. ammonia) in an aquatic environment. It becomes most lethal when oxygen becomes limited due to high fish densities or in the presence of high bacterial activity due to waste build-up-both situations commonly found in intensive aquaculture. To date however, little is known about how this toxin affects the physiology of walleye, an intended culture species, particularly in intensive re-circulating systems. This study aims to define threshold concentrations of nitrite that affect haemoglobin-oxygen affinity and carrying capacity in walleye. During in vivo tests, fish (N=20) were subjected to a medium effective concentration (EC50) of nitrite (0.9 mmol L(-1)) for 48 h while the effects of nitrite accumulation on blood properties were measured. The effects of oxygenation state on red blood cell (RBC) nitrite uptake and metHb formation was further investigated by in vitro tonometry. In vitro nitrite exposure to 3 mmol L(-1) resulted in a significantly higher methaemoglobin formation in 50% air saturated than 100% air saturated RBCs. Both cell water content and haematocrit decreased with time in 50% air saturated treatments, whereas total Hb remained constant, suggesting a reduction in RBC volume. Similar effects were observed during 48 h in vivo and in vitro nitrite exposure tests, indicating the reduction in RBC volume likely was not the result of a catecholamine response. Walleye were found to be tolerant to an accumulation of blood-NO2- levels similar to common carp, a highly Mean Cellular Volume (MCV) tolerant species, before succumbing to methaemoglobinemia. The elevated tolerance to nitrite of walleye is a beneficial characteristic for successful rearing in a culture setting, where reduced oxygen and elevated MCV levels are prevalent. The findings from this study may be used in developing guidelines for species-specific management of nitrogenous wastes in aquaculture. PMID:16806526

Alfred Francois Donné (1801-78): a pioneer of microscopy, microbiology and haematology.  


Alfred François Donné is widely known in the scientific community as the discoverer of Trichomonas vaginalis, since he was the first to illustrate the parasite that later was recognized to cause vaginal infections. However, his other, less-known findings are equally important: he was also the inventor of the photoelectric microscope, with the assistance of his student Léon Foucault, as well as the first to apply photography to microscopic preparations (Daguerreotype). His research in microscopy extended to almost all human fluids that could be investigated and culminated in his famous Atlas, which was illustrated with numerous photographs. Donné was also the first to describe the microscopic appearances of leukaemia based on blood preparations acquired from patients. Finally, his work in the hygiene of child upbringing and nutrition is very significant. PMID:19401511

The 'royal disease'--haemophilia A or B? A haematological mystery is finally solved.  


? 'History can change blood. And blood can change the course of history'. Haemophilia is an illustration of this, as this congenital hereditary coagulation disorder, passed through the majority of royal European families at the beginning of the 20th century by Queen Victoria of England and Empress of the Indies, had indisputable political consequences, which led to one of the most defining moments of contemporary history: the Bolshevik Revolution. Today, none of Queen Victoria's living descendents carry haemophilia. Because of this, the characterization of haemophilia (deficit of either factor VIII or XI) and the identification of the causal mutation are rendered impossible. In 1991, a tomb containing the remains of Czar Nicolas II's entire family was discovered. A second tomb was discovered in 2007, allowing Russian and American scientists to fill in this gap in medical history. Following a scientific approach combining current genetic experimentation tools and the development of biological information technology, researchers were able to identify each body, allowing them to obtain precious genetic material from the young Czar Alexis, who was stricken by the disease, which revealed a causal substitution in the splice acceptor site of exon 4 in the F9 gene. This mutation that is responsible for haemophilia B had traumatized European royal families throughout the 20th century! PMID:20557352

Desmopressin in treatment of haematological disorders and in prevention of surgical bleeding.  


Stimulation with the vasopressin analogue desmopressin (DDAVP) of extrarenal arginine vasopressin (AVP) V2-receptors in endothelial cells and possible in platelets increases the circulating levels of coagulation factor VIII (FVIII), von Willebrand factor (VWF) and tissue plasminogen activator (t-PA). The purpose of this paper is to provide an updated review of current information on the efficacy and safety of DDAVP in the treatment of haemophilia, von Willebrand disease (VWD), uremia, liver cirrhosis, and in congenital or drug-induced platelet dysfunction--under surgical or non-surgical conditions. In summary, desmopressin is an effective haemostatic drug that when administered i.v., s.c. or intranasally increases plasma levels of FVIII and VWF 2-6 times and improves platelet function. It has a proven haemostatic efficacy in mild haemophilia A and VWD as well as in uremia, liver cirrhosis and in congenital and acquired, drug induced platelet dysfunction. Desmopressin has few side effects but observation is advised in small children and elderly. PMID:24703870

Some Haematological and Biochemical Investigations on Duck Virus Hepatitis following Administration of Glycyrrhizin  

PubMed Central

The present study aimed to investigate the protective effect of glycyrrhizin (locally isolated and purified from licorice root) against duck hepatitis virus through the assessment of some hematological and biochemical parameters. One hundred and sixty white Pekin ducklings—one day old—were randomly divided into four equal groups. Group (1) was kept as normal control. Group (2) was inoculated I/P with 10?mg glycyrrhizin/kg BW, three times per week for four weeks. Group (3) was inoculated I/M with 0.5?ml of live attenuated DHV vaccine. Group (4) was inoculated with both glycyrrhizin (10?mg/kg BW I/P, three times per week for four weeks) and live attenuated DHV vaccine (0.5?ml, I/M). Then, all groups of treatment were challenged using virulent DHV except for 20 ducklings from the normal control group which were continued to be kept as negative control. The results revealed that duck hepatitis virus (DHV) caused macrocytic hypochromic anemia, leukopenia, hypoproteinemia, hypoalbuminemia, hyperglycemia, hypercholesterolemia, and marked elevation of liver enzymes and renal parameters. In conclusion, glycyrrhizin injected alone or in combination with DHV vaccine protected or ameliorated the deteriorating effects induced by DHV vaccine and/or duck hepatitis virus infection by improvement of erythrogram and leukogram, as well as liver and kidney functions.

Effect of combination of Capsicum frutescens and Citrullus colocynthis on growth, haematological and pathophysiological parameters of rats.  


The toxicity of diet containing 10% of Capsicum frutescens or 10% of Citrullus colocynthis fruits or their 1:1 mixture (5% + 5%) to rats treated for 6 weeks was evaluated. Body weight loss, inefficiency of feed utilization, diarrhoea, and enterohepatonephropathy characterized C. colocynthis toxicosis in rats. Despite impairment of rat's growth neither nephropathy nor diarrhoea was detected in rats fed the 10% C. frutescens diet. Feeding the mixture of C. frutescens and C. colocynthis caused more pronounced effects and death of rats. Vital organ lesions accompanied by anaemia and leucopenia were correlated with changes in serum ALP, AST and ALT activities with alterations in concentrations of total protein, albumin, urea and other serum constituents. Serum bilirubin concentration did not change. PMID:12557257

Trigonella foenum-graecum protection against deltamethrin-induced toxic effects on haematological, biochemical, and oxidative stress parameters in rats.  


Trigonella foenum-graecum L. is enriched with many active ingredients. TFG oil was evaluated for its protective effect against deltamethrin toxicity in rats. Rats of the control group were administered saline. The 2nd group was administered deltamethrin (DLM) orally at a concentration of 15 mg/kg body mass. The 3rd and 4th groups were administered DLM at a concentration of 15 mg/kg body mass and were fed diets containing 2.5% and 5% TFG oil, respectively. DLM intoxication reduced red blood cell and platelet counts, hemoglobin concentration, and hematocrit value while it induced leucocytosis. Furthermore, it increased serum levels of lactate dehydrogenase, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, ?-glutamyltransferase, triglycerides, cholesterol, uric acid, urea, and creatinine; increased hepatic, renal, and brain lipid peroxidation; decreased serum acetylcholine esterase level; and decreased hepatic, renal, and brain antioxidant markers' activities. However, TFG oil kept the studied hematological and biochemical parameters within normal ranges. In addition, it prevented lipid peroxidation and oxidative stress induced by DLM intoxication in a dose-dependent manner. Therefore, these results indicated that TFG oil inhibited the toxic effects of DLM on hematological and biochemical parameters as well as oxidative status by its free radical scavenging and potent antioxidant activities, and it appeared to be a promising protective agent against DLM-induced toxicity.

Effect of caffeine supplementation on haematological and biochemical variables in elite soccer players under physical stress conditions  

PubMed Central

Objective To evaluate the effect of caffeine on white cell distribution and muscle injury markers in professional soccer players during exercise. Methods 22 male athletes completed a placebo controlled double blind test protocol to simulate a soccer match, followed by a Yo?Yo intermittent recovery test. Results Exercise caused an increase in packed cell volume that was enhanced by caffeine. Caffeine and exercise had a synergistic effect on the blood lymphocyte count, which increased by about 38% after exercise, and by an additional 35% when combined with caffeine. Caffeine promoted an exercise independent rise in circulating monocytes, and a synergistic action of exercise and caffeine was observed on segmented neutrophils. Caffeine promoted thrombocytosis. Plasma adenosine deaminase, aspartate aminotransferase, and lactate dehydrogenase concentrations were enhanced by exercise, and alanine transaminase concentration was enhanced in both groups, with a synergistic effect of caffeine. Conclusions The pronounced increase in the white cell count in the group receiving caffeine appeared to be caused by greater muscle stress and consequently more intense endothelial and muscle cell injury. The use of caffeine may augment the risk of muscle damage in athletes. PMID:17473001

Experimental infection of rabbits with Fasciola gigantica and treatment with triclabendazole (TCBZ) or BT6: parasitological, haematological and immunological findings.  


The responses of rabbits experimentally infected orally with 25 Fasciola gigantica metacercariae each, to treatment with triclabendazole (TCBZ) in a single oral dose of 10 mg/Kg body weight or with the newly synthesized drug (BT6) in repeated oral doses of 500 mg/Kg for 3 consecutive days, were monitored by faecal egg and fluke counts and the enzyme-linked immunosorbent assay (ELISA), both treatments at 4-, 8- and 12- weeks of infection. In all infected rabbits, eggs appeared in the faeces between 10 and 16 weeks post-infection (P1) and Were egg-negative in the TCBZ-treated animals. Compared with the infected untreated control (group B), the reduction in the fluke burdens were 93.75,100 and 100% in TCBZ-treated rabbits (groups C, D and E), respectively and 33.33, 27.08 and 27.08% in the BT6 treated groups F, G and H, respectively. Total red blood corpuscle (RBCs) counts, haemoglobin (Hb) concentration and packed-cell volume (PCV) values in rabbits (group B) indicated the presence of moderate anaemia from the start of infection with a significant decrease from 10-12 weeks onwards. RBCs count, Hb and PCV values from groups C, D and E were significantly higher (p < 0.001) than in those from group B on week 10, 8 and 10 PI, respectively. The increasing was continued till week 16 PI. By two weeks PI there was significant eosinophilia in infected rabbits, maintained at 4 and 6 weeks PI then dropped up to 8 weeks but still statistically higher than the control values. The ELISA detected antibodies against F. gigantica as early as week 2 PI, rising to high levels 6, 10 and 12 weeks later in groups C, D and E, respectively, whilst peaked at 10 weeks in BT6 treated animals, then tended to drop but remained positive through 16 weeks. We conclude TCBZ is a potent fasciolicidic drug. Eosinophilia and anaemia might be indicators for fascioliasis. The ELISA with adult fluke excretory - secretory (ES) antigens could be a feasible method for the diagnosis of experimental fascioliasis in rabbits and post-treatment monitoring. PMID:17216940

Haematological complete remission by ponatinib and bortezomib in a patient with relapsed, Ph? pre-B acute lymphoblastic leukaemia.  


A 74-year-old man was previously diagnosed with BCR-ABL1-positive pre-B cell acute lymphoblastic leukaemia (pre-B ALL) based on bone marrow cytology, flow cytometry, cytogenetics and fluorescent in situ hybridisation findings. Following a highly complicated hospital course, the patient achieved cytogenetic remission by consolidated chemotherapy and the tyrosine kinase inhibitor dasatinib. He subsequently presented with relapsed pre-B ALL after 3 years in remission. In consideration of his challenging clinical history, he was started on concurrent ponatinib (45 mg daily) and bortezomib (1.3 mg/m(2) intravenous weekly). The major molecular response was achieved (<0.0893% BCR-ABL1 transcripts) after 3 months. Bone marrow now demonstrates a BCR-ABL1-negative, complete cytogenetic response. The patient continues to do well with mild thrombocytopenia and improved anaemia on bortezomib and 30 mg daily ponatinib. Our experience with a single patient suggests the feasibility of combined targeted therapy with ponatinib and bortezomib. This novel treatment approach achieved clinical remission with a manageable toxicity profile. PMID:24729118

Serum Cu was significantly lower in the dry than in the wet season (P < 0.001) with a corresponding high percentage of samples with low Cu levels in the former. 31% of dry nonpregnant sheep exhibited a nonregenerative anaemia. Also, hemoglobin and packed cell volume values varied (P < 0.001) including lymphocyte (P < 0.01) counts, among growing animals compared with other physiological stages. Significant variations also occurred among neutrophil (P < 0.05) and eosinophil (P < 0.05) values in sheep. Highest haemoglobin and packed cell volume, white blood cell counts, and lymphocyte values in growing sheep compared with other stages were probably age related. PMID:24895542

Effect of sulphurous mineral water in haematological and biochemical markers of muscle damage after an endurance exercise in well-trained athletes.  


To investigate the effects of sulphurous mineral water (SMW) after a hydroponic treatment on muscle damage, antioxidant activity and peripheral blood changes induced by submaximal exercise. Thirty well-trained male triathletes were supplemented with SMW or placebo: 3 weeks of placebo, 30 days of wash out and 3 weeks of SMW. After both periods, participants ran for 2 h at 70% maximal aerobic speed. Antioxidant enzymes, lipid peroxidation, antioxidant capacity and blood cell markers were compared between placebo and SMW at pre-exercise (T0), immediately post-exercise (T1), 24 h post-exercise (T2) and 48 h post-exercise (T3). Total thiols decreased until T3 vs. T0 for both placebo and SMW; transient red blood cells, haemoglobin and haematocrit increased were shown at T1 vs. T0 and for leucocytes until T2 vs. T0, only for placebo group. Total thiols increased significantly in SMW vs. placebo at T0; Thiobarbituric acid reactive species was significantly higher at T0, T1, T2 and T3; catalase increased significantly at T1; creatine phosphokinase decreased significantly at T1, T2 and T3, although no significant differences were found at T0. Furthermore, red blood cells, haemoglobin and haematocrit were significantly higher and leucocytes were significantly lower at T0 and T1 in SMW group vs. placebo group. This study suggests that three weeks of SMW supplementation may protect from exercise-induced muscle damage. PMID:24499262

SUMMARY Exposure of adult rainbow trout to low pH (4-0-4-5) for 3 days resulted in progressive increases in heart rate, mean arterial blood pressure and haema- tocrit. The haematocrit increase resulted from erythrocyte swelling, a re- duction in plasma volume and a mobilization of erythrocytes from the spleen. Erythrocyte swelling probably resulted from plasma acidosis and a reduction in plasma



Evaluation of Biochemical, Haematological, and Histopathological Responses and Recovery Ability of Common Carp (Cyprinus carpio L.) after Acute Exposure to Atrazine Herbicide  

PubMed Central

The aim of study was to evaluate the effect of atrazine exposure (5, 15, 20, and 30?mg·L?1) on common carp and the ability of regeneration. During 96?h exposure we observed abnormal behavior in fish exposed to 20 and 30?mg·L?1. Mortality and histological alterations were noticed only in the group exposed to 30?mg·L?1. Most experimental groups showed significantly (P < 0.05) lower values of haemoglobin, haematocrit, leukocyte, and lymphocyte and significantly higher values of monocytes, segmented and band neutrophile granulocytes, and also metamyelocytes and myelocytes. A significantly lower (P < 0.05) leukocyte count was also recorded in experimental groups (5 and 15?mg·L?1) after recovery period. Statistically significant (P < 0.05) alterations in glucose, total protein, lactate, phosphorus, calcium, and biopterin as well as in activities of ALT, AST, ALP, and LDH were found in most experimental groups. These changes were most apparent in the groups exposed to 20 and 30?mg·L?1. Most of the indices were found to be restored after the 7-day recovery period with the exception of LDH, ALT, and lactate in the group exposed to 15?mg·L?1. Our results showed that atrazine exposure had a profound negative influence on selected indices and also on histological changes of common carp. PMID:24791011

Effect of gavage treatment with pulverised Garcinia kola seeds on erythrocyte membrane integrity and selected haematological indices in male albino Wistar rats.  


This study examines the effect of the whole seed of Garcinia kola [GKS] on various blood parameters, in adult male albino rats. Five groups, of 6 animals per group, were treated by gavage with suspensions of graded concentrations of GKS daily for 5 weeks. The animals were then sacrificed and blood was obtained for estimation of the data herein presented. Packed red cell volume [PCV], hemoglobin concentration [Hb], and red blood cell count [RBC] showed significantly [P<0.05], increased response to treatment with GKS; while the platelet and white blood cell [WBC] counts showed no corresponding increase with increasing GKS dosage. The mean red blood cell volume [MCV] and mean cell hemoglobin [MCH] levels decreased with increasing GKS dosage. Prothrombin time [PT] and activated partial thromboplastin time [APPT] were both prolonged with increased GKS dosage; while the serum lipids (cholesterol and triglycerides) decreased significantly [P<0.05] with increased GKS dosage.

A short evaluation of a new haematological cell counter--the Cell-Dyn 3000--following a modified tentative NCCLS-procedure.  


The proposed procedure offers a method of evaluation that is feasible, but still a very precise method, for the evaluation of electronic differential leukocyte counters. Following this abbreviated method, the classification of the leukocytes, from 5 x 20 unselected blood specimens, with a flow-cytometric analysis by the Sequoia Turner Cell-Dyn 3000, was compared with microscopic differential counts as the standard. With proven accuracy and good reproducibility, the Cell-Dyn 3000 is a good sieve for the selection of normal samples. The high sensitivity and fair specificity permits a reduction of the differential workload to about 30 percent of the normal workload. PMID:2049478

service guidance is to guide the commissioning of services and is therefore different from clinical practice guidelines. Health services in England and Wales have organisational arrangements in place for securing improvements in cancer services and those responsible for their operation should take this guidance into account when planning, commissioning and organising services for cancer patients. The recommendations in the guidance concentrate on aspects of services that are likely to have significant impact on health outcomes. Both the anticipated benefits and the resource implications of implementing the recommendations are considered. This guidance can be used to identify gaps in local provision and to check the appropriateness of existing services.

Studies on Parasitologic and Haematologic Activities of an Enaminone Derivative of 4-Hydroxyquinolin-2(1H)-one Against Murine Schistosomiasis Mansoni  

PubMed Central

The activity of a novel enaminone derivative of 4–hydroxyquinoline, BDHQ, was screened for its effectiveness against murine schistosomiasis by electron microscopy and parasitologic studies. The correlation of these studies with serum levels of IFN–gamma and IgE is described. Two groups of 10 mice each were treated with different doses of BDHQ, and their results were correlated with the control and praziquantel (PZQ)–treated groups. Parasitologic study revealed significant reduction in mature worms and tissue egg loads in BDHQ– and PZQ–treated groups, whereas immature worms revealed significant reduction in BDHQ groups only. The group treated with a higher dose of BDHQ showed significant reductions in intestinal ova count when compared with the PZQ–treated group. Ultrastructural examination of the worm revealed significant degeneration of the spines and tegument in all treated groups, while the genital system was affected in BDHQ–treated groups only. BDHQ showed considerable effect on cellular activation where serum levels of IFN–gamma were significantly increased in comparison to control, while anti–soluble worm antigen preparation (SWAP) IgE was significantly increased in comparison to both the control and PZQ–treated groups. Ultrastructural examination revealed cellular activation in buffy coat and the liver in both the BDHQ– and PZQ–treated groups in comparison to the untreated one, whereas in the bone marrow and spleen, evidence of cellular activation was remarkable in the BDHQ–treated groups. In conclusion, BDHQ exhibits high levels of activity against adult and juvenile stages of these parasites, which may be due to its mixed cellular and humoral immunologic mechanisms, as demonstrated by the significant increase of serum levels of IgE and IFN–gamma shown on electron microscopy. Therefore, our results support the comparative advantage that BDHQ has over PZQ. PMID:17435624

Compliance with home-based fortification strategies for delivery of iron and zinc: its effect on haematological and growth markers among 6-24 months old children in north India.  


Compliance is a key component in successful implementation of the delivery of micronutrients among children. The present study evaluates the compliance with two home-based food fortification strategies (fortified complementary food or sprinkle) for providing iron and zinc among children aged 6-24 months. A total of 292 children were randomly allocated to receive either rice-based fortified complementary food and nutrition education (Cf = 101), sprinkle and nutrition education (Mp = 97), or nutrition education alone as control (Ed = 94). All the enrolled children were breastfed at the beginning of the study and were advised to continue breastfeeding. Biweekly information on compliance and anthropometry was collected. Complete haemogram estimation was conducted at baseline and end of the study. Compliance with the fortified complementary food was higher compared to sprinkle (Cf = 81%, Mp = 64% child-days). Consumption of the fortified complementary food for 6 months resulted in a significant increase in mean haemoglobin in the intervention group compared to control group (Cf 1.29 +/- 1.6 g/dL; Ed 0.23 +/- 1.3 g/dL; p < 0.001). Our results showed that fortified complementary food had higher compliance than sprinkle and is a suitable delivery mechanism for iron and zinc in preschool children. PMID:25076659

A comparison of high resolution melting, allele-specific priming and Sanger sequencing for the detection of BRAFV600E mutation in hairy cell leukaemia from different haematological specimens.  


The BRAFV600E mutation is a highly sensitive and specific marker for the diagnosis of hairy cell leukaemia (HCL) and a potential therapeutic target. We assessed the performance of high resolution melting (HRM), allele-specific priming (ASP) and Sanger sequencing (SS) for BRAFV600E detection in 17 unenriched samples from 15 HCL patients: blood (n?=?7), marrow aspirate (n?=?3), ethylenediaminetetraacetic acid (EDTA)-decalcified trephine biopsy (n?=?2), formic acid (FA)-decalcified trephine biopsy (n?=?5). Our results showed that for blood and marrow aspirate samples, both HRM and ASP had a very high analytical sensitivity (1%) in clinical specimens and excellent diagnostic sensitivity (100%) and specificity (100%) in analysable samples. Sanger sequencing had a lower analytical sensitivity (4%), resulting in false-negative analysis in samples with a low tumour cell percentage. High resolution melting was technically the simplest and had the shortest turn-around time (2?hours). Analysis of decalcified trephine biopsies was more difficult because of suboptimal DNA preservation. Although Sanger sequencing was least demanding on sample DNA quality for a successful analysis, none of the three techniques showed satisfactory diagnostic performance on trephine biopsies. Therefore, careful selection of a suitable sample type and testing platform is important to optimise the detection of this important mutation in HCL. PMID:25158814

Prognostic impact of karyotypic findings in childhood acute lymphoblastic leukaemia: a Nordic series comparing two treatment periods. For the Nordic Society of Paediatric Haematology and Oncology (NOPHO) Leukaemia Cytogenetic Study Group.  


The prognostic impact of acquired chromosome abnormalities was evaluated in a population-based consecutive series of 768 children (< 15 years of age) with acute lymphoblastic leukaemia (ALL). The study cohort included all cases of cytogenetically abnormal childhood ALL diagnosed between 1986 and 1997 in the five Nordic countries (Denmark, Finland, Iceland, Norway and Sweden). The probability of event-free survival (pEFS) for the total cohort was 0. 72 +/- 0.02. When comparing the two treatment periods of July 1986 to December 1991 and January 1992 to December 1997, a better survival was seen for the latter time period (pEFS of 0.69 +/- 0.02 vs. 0.76 +/- 0.02, P = 0.05). Hypodiploidy with less than 45 chromosomes, t(9;22)(q34;q11) and 11q23 translocations were associated with a dismal outcome during the whole study period (pEFS of 0.57 +/- 0.12, 0.41 +/- 0.14 and 0.37 +/- 0.10 respectively). The poor prognostic influence of 11q23 rearrangements seemed to be restricted to infants and older children (> 10 years), who differed significantly from children aged 1-10 years in this regard (P < 0. 01). Patients with t(9;22)-positive ALL seemed to benefit from allogeneic bone marrow transplantation in first remission (P = 0.05). The pEFS for children with t(1;19)(q23;p13)-positive ALL was intermediate (0.63 +/- 0.17), with a tendency to a better outcome for patients with the unbalanced variant der(19)t(1;19). Hyperdiploid ALL patients, subdivided into moderate hyperdiploidy (47-51 chromosomes), massive hyperdiploidy (52-60 chromosomes) and cases in the tri-/tetraploid range (> 60 chromosomes) had the best outcome in the last treatment period (pEFS of 0.81 +/- 0.06, 0.80 +/- 0.04 and 0.88 +/- 0.07 respectively), unless t(1;19), t(8;14), t(9;22) or 11q23 translocations were present. In a multivariate analysis including white blood cell (WBC) count, immunophenotype, age, mediastinal mass, central nervous system involvement and leukaemia karyotype, only WBC and modal chromosome number were shown to be significant independent risk factors (P < 0.01).

An unusual cause for recurrent jaundice in an otherwise healthy male  

PubMed Central

A 41-year-old Asian-Indian male presented with recurrent episodes of jaundice over the past six months. Physical examination was normal, barring mild icterus. Laboratory parameters revealed indirect hyperbilirubinemia. Further evaluation yielded a diagnosis of severe nutritional vitamin B12 deficiency. Indirect hyperbilirubinemia was ascribed to ineffective erythropoiesis. Underlying Gilbert's syndrome was ruled out by provocative testing with lipid-restricted diet. Presentation of severe vitamin B12 deficiency with isolated hyperbilirubinemia without concomitant major haematologic or neurologic dysfunction is unusual and potentially underdiagnosed. Awareness of this possibility can permit early diagnosis of vitamin B12 deficiency and forestall development of severe haematologic and neurologic sequelae. PMID:23173018

[Hematological abnormalities in rheumatic diseases].  


Haematological abnormalities are present in 25-50% patients with rheumatic diseases. The most common finding is anaemia of chronic disease which is driven by inflammatory cytokines. Hepcidin plays key role in iron homeostasis. It reduces iron absorption from duodenum and iron release from reticuloendothelial cells. Anaemia of chronic disease could be successfully treated by recombinant erythropoietin in combination with iron supplementation. Various abnormalities can be observed in the leukocyte and platelets counts. Other haematological disturbances are considered as part of autoimmune disease. Prolonged antigen stimulation can induce lymphomagenesis and lymphoma incidence in patients with rheumatic diseases is 5 to 6-fold increased compared to normal population. PMID:17580549

Changes in non-specific biomarkers in the Mediterranean barbel (Barbus meridionalis) exposed to sewage effluents in a Mediterranean stream (Catalonia, NE Spain).  


The effluents from sewage treatment plants strongly influence the water quality and flow of Mediterranean streams. These effluents play a crucial role in maintaining the aquatic communities of these ecosystems, particularly in the absence of natural flow resulting from climate constraints or intensive water use. To detect the ecological effects of these effluents, we used non-lethal biomarkers in Barbus meridionalis and traditional assessment protocols in the Ripoll River (NE of Spain). Our results demonstrate the utility of haematological parameters. In comparison with fish at reference sites, we detected a decrease in haematocrit and haemoglobin, neutrophilia, lymphopenia, monocytosis, a rise in the nucleo-cytoplasmatic ratio of erythrocytes and an increase in the frequency of abnormal, immature and senescent erythrocytes. Many haematological parameters correlated significantly with the environmental parameters measured. In addition to these haematological alterations, histopathological examination also revealed damage in fish livers but no impact was detected by the regional index of biotic integrity using fish as bioindicators. To the best of our knowledge, this study is the first to report this battery of haematological parameters as biomarkers on a freshwater fish in a Mediterranean stream. In a region in which more than 50% of native fish species are classified as endangered or vulnerable, there is an urgent need to find biomarkers that do not harm the animals. PMID:20810176

Severe encephalopathy with epilepsy in an infant caused by subclinical maternal pernicious anaemia: case report and review of the literature  

Microsoft Academic Search

Vitamin B 12 deficiency is one of the major causes of megaloblastic anaemia with or without neurological symptoms. We report on a patient manifesting acute encephalopathy, epilepsy, microcephaly and megaloblastic anaemia at the age of 4 months. Vitamin B 12 deficiency in the patient was due to subclinical pernicious anaemia of the mother who exhibited neither haematological nor neurological symptoms.

Importance of neurological assessment before bone marrow transplantation for osteopetrosis

Neurological complications of malignant infantile osteopetrosis are well recognised; successful bone marrow transplantation, when performed early in life, can prevent or halt some of them. In a subgroup of infants osteopetrosis is associated with primary retinal degeneration and\\/or generalised neurodegeneration. Bone marrow transplantation, in spite of being successful in correcting the osseous and haematological abnormalities, does not influence the progressive

The effects of offshore aquaculture on SBT health (particularly parasitic infections and haematology) and performance were the main aim of this study. Two cohorts of ranched Southern Bluefin tuna (SBT) (Thunnus maccoyii) were monitored throughout the commercial season, one maintained in the traditional near shore tuna farming zone and one maintained further offshore. SBT maintained offshore had reduced mortality, increased condition index at week 6 post transfer, reduced blood fluke and sealice loads, and haematological variables such as haemoglobin or lysozyme equal to or exceeding near shore maintained fish. The offshore cohort had no Cardicola forsteri and a 5% prevalence of Caligus spp., compared to a prevalence of 85% for Cardicola forsteri and 55% prevalence for Caligus spp. near shore at 6 weeks post transfer. This study is the first of its kind to examine the effects of commercial offshore sites on farmed fish parasites, health and performance. PMID:21901129

Non-infectious pulmonary complications after bone marrow transplantation  

PubMed Central

Bone marrow transplantation (BMT) is a successful and recognised treatment option for patients with a number of haematological and non-haematological malignant and non-malignant conditions. Pulmonary complications both infectious and non-infectious are common after BMT. Multiple factors are thought to contribute to pulmonary complications, including the type and duration of immunological defects produced by the underlying disease and treatment, the development of graft-versus-host disease (GVHD), and the conditioning regimens employed. These complications are classified as early or late, depending on whether they occur before or after 100 days from transplantation. Early non-infectious pulmonary complications typically include pulmonary oedema, upper airway complications, diffuse alveolar haemorrhage, cytolytic thrombi, and pleural effusion. Bronchiolitis obliterans, veno-occlusive disease, and secondary malignancies occur late after BMT. Idiopathic pneumonia syndrome, GVHD, and radiation induced lung injury can occur in early or late period after BMT. PMID:12151565

1 UK-37248 (dazoxiben), an orally active thromboxane synthetase inhibitor, was evaluated in a double-blind trial of patients with severe Raynaud's syndrome. 2 Twenty patients were enrolled in the study. Eleven of these patients received dazoxiben 400 mg day and nine received matching placebo capsules. Treatment was given for 6 weeks and the patients reviewed at 2 weekly intervals during the study. 3 Assessment of response was judged by clinical symptoms and hand temperature measurements. Haematological and haemostatic studies were also carried out. 4 Results show a significant clinical improvement in patients receiving dazoxiben for six weeks Hand temperature measurements, and haematological and haemostatic blood tests remained unchanged, however, apart from the expected lowering in plasma thromboxane B2 levels. 5 The mechanism of action of the drug would appear not to be mediated through increased prostacyclin production and further studies are under way to determine how improvement has been obtained in these patients.

Storage of equine red blood cells as a concentrate.  


The study was undertaken to determine how equine red blood cells (RBCs) survive in storage bags designed for use with human RBCs. Separated RBCs were stored in a routine manner for 35 days and examined every 7 days for storage lesions. Measured parameters included haematology, haemolysis, pH, potassium, lactate, adenosine triphosphate (ATP) and 2,3-diphosphoglycerate (2,3-DPG). All tests were performed in vitro. Haematology did not change significantly. Haemolysis increased during storage but did not exceed human limits. pH and 2,3-DPG decreased, while lactate, potassium and ATP increased. RBCs deteriorated somewhat during storage, but when compared with human in vitro parameters, remained suitable for transfusion. It is concluded that equine erythrocytes can be stored for at least 35 days before transfusion. PMID:17449302

Pathophysiology of white-nose syndrome in bats: a mechanistic model linking wing damage to mortality.  


White-nose syndrome is devastating North American bat populations but we lack basic information on disease mechanisms. Altered blood physiology owing to epidermal invasion by the fungal pathogen Geomyces destructans (Gd) has been hypothesized as a cause of disrupted torpor patterns of affected hibernating bats, leading to mortality. Here, we present data on blood electrolyte concentration, haematology and acid-base balance of hibernating little brown bats, Myotis lucifugus, following experimental inoculation with Gd. Compared with controls, infected bats showed electrolyte depletion (i.e. lower plasma sodium), changes in haematology (i.e. increased haematocrit and decreased glucose) and disrupted acid-base balance (i.e. lower CO2 partial pressure and bicarbonate). These findings indicate hypotonic dehydration, hypovolaemia and metabolic acidosis. We propose a mechanistic model linking tissue damage to altered homeostasis and morbidity/mortality. PMID:23720520

Molecular basis of mast cell disease.  


Mastocytosis is an incurable and sometimes fatal haematological disorder grossly described as the accumulation of abnormal mast cells in the bone marrow and other organs causing tissue and organ damage. The clinical manifestations of this disease are extremely variable; disease phenotypes range from indolent to aggressive, and often present with associated non-mast cell haematological disorders (AHNMD), mainly myeloproliferative neoplasm and myelodysplastic syndromes. Recent efforts to genetically dissect the mechanisms that define aggressive and non-aggressive mastocytosis have generated a list of recurrent somatic mutations in mastocytosis patients that are associated with and may predict the evolution towards aggressive disease phenotypes. Here we review these mutations and discuss the molecular mechanisms associated with these mutations in an effort to better understand the biology of this disease and to predict its onset and evolution, with the ultimate goal of devising new and improved treatment strategies.

[Selected problems concerning anaemia in systemic lupus erythematosus patients].  


Haematological abnormalities are common in systemic lupus erythematosus (SLE) and may be manifested by anaemia of different pathogenesis. The objective of this article was to describe some data concerning autoimmune haemolytic anaemia, aplastic and megaloblastic ones accompanying SLE and also to present erythropoietin (EPO) function in the above mentioned diseases. In SLE many factors are produced which disturb the organism haematological balance both on the peripheral level and in the bone marrow. It is assumed that the autoantibodies produced in SLE are the main cause of anaemia. However it should be considered that quantitative changes in the number of erythrocytes observed in this disease are also caused by chronic inflammatory condition, which as the element of autoimmune disease impairs the endocrine function of the kidneys in EPO production. It influences bone marrow, iron metabolism and then haemopoiesis. Apart from humoral factors the role of mechanisms connected with immune cellular response is also considered. PMID:20120718

A cluster of septicaemias due to several water-related species occurred in a haematological unit of a university hospital. In recurrent septicaemias of a leukaemic patient caused by Sphingomonas paucimobilis, genotyping of the blood isolates by use of random amplified polymorphic DNA-analysis verified the presence of two distinct S. paucimobilis strains during two of the separate episodes. A strain of S. paucimobilis identical to one of the patient's was isolated from tap water collected in the haematological unit. Thus S. paucimobilis present in blood cultures was directly linked to bacterial colonization of the hospital water system. Heterogeneous finger-printing patterns among the clinical and environmental isolates indicated the distribution of a variety of S. paucimobilis clones in the hospital environment. This link also explained the multi-microbial nature of the outbreak. PMID:11886195

Pathophysiology of white-nose syndrome in bats: a mechanistic model linking wing damage to mortality  

USGS Publications Warehouse

White-nose syndrome is devastating North American bat populations but we lack basic information on disease mechanisms. Altered blood physiology owing to epidermal invasion by the fungal pathogen Geomyces destructans (Gd) has been hypothesized as a cause of disrupted torpor patterns of affected hibernating bats, leading to mortality. Here, we present data on blood electrolyte concentration, haematology and acid–base balance of hibernating little brown bats, Myotis lucifugus, following experimental inoculation with Gd. Compared with controls, infected bats showed electrolyte depletion (i.e. lower plasma sodium), changes in haematology (i.e. increased haematocrit and decreased glucose) and disrupted acid–base balance (i.e. lower CO2 partial pressure and bicarbonate). These findings indicate hypotonic dehydration, hypovolaemia and metabolic acidosis. We propose a mechanistic model linking tissue damage to altered homeostasis and morbidity/mortality.

Sudden death in a patient with bone marrow transplant by a fungus among us.  


Mucormycosis is rare, presenting as breakthrough infection among haematological and transplant patients on prophylaxis with voriconazole. We report an unusual presentation of this infection, that which is pneumonia progressing to cardiac arrest. A 68-year-old woman with refractory acute myelogenous leukaemia on voriconazole prophylaxis was initially admitted for neutropenic fever and pneumonia. She was discharged improved on antibiotics and voriconazole for presumed aspergillosis. She returned after 1?month with the same presentation. She eventually improved on antibiotics and voriconazole, and eventually received bone marrow transplantation. Three days later, she developed pleuritic chest pain, dyspnoea, and hypoxia requiring intubation. An hour after intubation, the patient arrested and expired. Autopsy revealed Rhizopus pneumonitis with pulmonary infarction, and emboli to her cerebellum, heart, thyroid and kidney. Mucormycosis is an emerging, fatal infection that should be suspected in haematological and transplant patients who deteriorate on voriconazole. PMID:25391828

Cerebral Atrophy in a Vitamin B12-deficient Infant of a Vegetarian Mother  

PubMed Central

ABSTRACT In developed countries, vitamin B12 (cobalamin) deficiency usually occurs in children, exclusively breastfed ones whose mothers are vegetarian, causing low body stores of vitamin B12. The haematologic manifestation of vitamin B12 deficiency is pernicious anaemia. It is a megaloblastic anaemia with high mean corpuscular volume and typical morphological features, such as hyperlobulation of the nuclei of the granulocytes. In advanced cases, neutropaenia and thrombocytopaenia can occur, simulating aplastic anaemia or leukaemia. In addition to haematological symptoms, infants may experience weakness, fatigue, failure to thrive, and irritability. Other common findings include pallor, glossitis, vomiting, diarrhoea, and icterus. Neurological symptoms may affect the central nervous system and, in severe cases, rarely cause brain atrophy. Here, we report an interesting case, a 12-month old infant, who was admitted with neurological symptoms and diagnosed with vitamin B12 deficiency. PMID:25076673

Angina bullosa haemorrhagica.  


A woman in her early 40s presented with a painless ulceration on the right side of the posterior palate, she had an earlier history of similar lesions after the rupturing of blood filled blisters in the oral cavity. On examination, a diffuse erythematous area and ulcers covered with necrotic slough were noticed on the right and left side of the posterior palate and on the right buccal mucosa. On follow-up visit, a large blood filled blister was noticed in the buccal vestibule. We advised routine haematological investigations to rule out any bleeding disorders and direct immunofluorescence of the affected tissue and perilesional areas to rule out autoimmune blistering conditions. Haematological investigations revealed no abnormalities and immunofluorescence testing was negative. A diagnosis of angina bullosa haemorrhagica was made by excluding all other conditions. Symptomatic treatment was given, patient was educated about the condition and reassured. PMID:24334011

The role of splenectomy in HIV-infected patients with relapsing visceral leishmaniasis.  


The treatment of visceral leishmaniasis (VL) in HIV-infected patients is characterized by having a protracted course and frequent relapses, despite the use of adequate anti-leishmanial drugs and effective anti-retroviral therapy. A small subset of patients with significant splenomegaly develops severe cytopaenias and chronic leishmania infection. The use of elective splenectomy is effective for restoring the haematological parameters and reduces the need for blood transfusions but it does not avoid relapsing visceral leishmaniasis.

Haematotoxicity of doxorubicin and 1-(2-chloroethyl)-3-cyclohexyl-1-nitrosourea (CCNU) and of their association in rats.  


Doxorubicin is an anthracycline widely used in the treatment of leukaemias, lymphomas and solid tumors. Doxorubicin cannot pass into the cerebrospinal fluid. Nitrosoureas are known to be lipophilic and to be able to penetrate the blood-brain barrier. CCNU is a nitrosourea used to treat Hodgkin's disease, brain tumors and other solid tumors. The authors have previously reported on the nephrotoxicity and hepatotoxicity of these drugs; the present paper reports their findings on haematotoxicity in female Wistar rats. In one group 40 rats received 10 mg/kg doxorubicin. In a second group 40 rats received 20 mg/kg CCNU, and a further 40 rats received 50 mg/kg CCNU. In a third group 60 rats received the association doxorubicin 10 mg/kg plus CCNU 20 mg/kg. Blood counts were performed on days 4, 8, 15, 21 and 28 after treatment. Leucopenia and severe thrombocytopenia were noted after doxorubicin administration. A biphasic decrease in the leucocyte count was observed after CCNU treatment. More severe alterations were observed when doxorubicin and CCNU were combined. Very few data on haematological abnormalities following treatment of human patients have been published. Similarities can be seen between the haematological side-effects noted in rats and those occurring in humans treated with these cytotoxic drugs. Female Wistar rats seemed to be a good model to evaluate the haematological tolerance of anthracycline, nitrosoureas or of their association. If multiple courses of these drugs have to be administered, the evolution of haematological alterations must be known: the decrease phase of blood cells is followed by a rebound phase. The drug should be avoided during this phase of granulocyte activation. PMID:3428123

Mandibulofacial dysostosis. Case report.  


A case of mandibulofacial dysostosis (Treacher Collins syndrome) is presented. Clinical features and skull radiographs revealed typical anomalies associated with the syndrome. Cleft of the soft palate and unerupted multiple supernumerary teeth were present in this case. No haematological, biochemical or immunological abnormalities could be detected in the patient. Pedigree analysis showed an autosomal dominant mode of transmission of the disease. Chromosomal studies did not reveal any structural or numerical discrepancies. PMID:7710415

Obesity associated pathophysiological & histological changes in WNIN obese mutant rats  

PubMed Central

Background & objectives: WNIN/Ob (obese and euglycaemic) and WNIN/GR-Ob (obesity with impaired glucose tolerance), were isolated and established from Wistar rat stock (WNIN). Both strains showed physical, physiological and biochemical indices related to obesity. We present here haematology, histology and pathophysiological changes between the phenotypes of these strains, lean (+/+), carrier (+/-) and obese (-/-). Methods: A total of 72 animals of equal gender consisting of three phenotypes were used for the study. Haematology, organ weights were measured and histopathology of the tissues studied using standard procedures. In 12 lean and obese rats (equal gender) of WNIN/GR-Ob group morphometry of pancreatic islets was done immunohistochemically (IHC). Results: Obese rats of both the strains showed normal haematology (except low platelet count), but exhibited changes in the organ weights and in histopathology in organs like liver, kidney, brain and testis/ovary. Hyperplasia of adipocytes was seen in obese rats as compared to lean and carrier. IHC of obese rat pancreas showed that both islet density and volume were significantly (P<0.05) increased compared to lean littermates. Interpretation & conclusions: The histological and pathophysiological changes seen in these mutants were in tune with obese phenotype exhibited by these animals. PMID:21985816

Does Oral Ingestion of Piper sarmentosum Cause Toxicity in Experimental Animals?  

PubMed Central

The prevalence of diabetes mellitus has reached epidemic proportion in Malaysia and worldwide. Scientific studies have shown that herbal plant Piper sarmentosum exhibits an antidiabetic property. Despite the extensive usage and studies of this herb as alternative medicine, there is paucity of the literature on the safety information of this plant. Thus, the present study aimed to observe the subacute toxic effects of Piper sarmentosum aqueous extract (PSAE) on the haematological profile, liver, and kidney in rats. The extract was administered by oral gavage to 6 male and female Sprague Dawley rats in daily dose of 50?mg/kg, 300?mg/kg, and 2000?mg/kg for 28 consecutive days. The control group received normal saline. General behavior of the rats, adverse effects, and mortality were observed for 28 days. The haematological and biochemical parameters were determined at baseline and after the treatment. PSAE did not show abnormality on the body weight and gross observation of internal organs. The haematological, biochemical and histopathological profiles showed minimal changes and variation within normal clinical range except for significant increase in serum potassium level that suggests the need of regular monitoring. Nevertheless, these findings suggested that PSAE up to 2000?mg/kg/day did not show subacute toxicity in Sprague Dawley rats. PMID:24228062

Uptake and excretion of iron by healthy elderly subjects.  

PubMed Central

Metabolic balance studies for iron have been carried out on 24 apparently healthy elderly people (11 men and 13 women) aged 69.7 to 85.5 years living in their own homes and eating self selected diets. Several biochemical and haematological indices of iron state were also measured. The mean daily iron intake was 176 mumol, with a range of 55-321 mumol. Eight women and six men consumed diets which provided less than the recommended daily dietary allowance for iron of 179 mumol/day. Mean daily retention of iron, however, was -7 mumol, a value which did not significantly differ from equilibrium. No sex difference was noted between any of the biochemical and haematological measurements. Mean values of iron concentration, iron binding capacity, iron binding saturation, and ferritin and haemoglobin concentrations were 20 mumol/l, 59 mumol/l, 34%, 77 micrograms/l, and 14.3 g/dl, respectively. We have shown that in apparently healthy elderly people who are in equilibrium for iron balance, several biochemical and haematological measurements of iron state do not differ from the normal ranges established in younger adults.

Interactions of Plasmodium juxtanucleare and chicken anaemia virus: establishing a model.  


The pathogens Plasmodium juxtanucleare and chicken anaemia virus (CAV) are easily transmitted and potentially harmful to chickens. In this study, we established an experimental model to investigate the effects of avian malaria caused by P. juxtanucleare in white leghorn specific-pathogen-free (SPF) chicks previously immunosuppressed with CAV. Parasitaemia, haematological variables and clinical and pathological parameters were determined in four different experimental groups: chicks coinfected by CAV and P. juxtanucleare strain (Coinfected group), chicks exclusively infected by CAV (CAV group) or P. juxtanucleare (Malaria group) and uninfected chicks (Control group). Our data demonstrated that P. juxtanucleare parasitaemia was significantly higher in the Coinfected group. Furthermore, haematological parameters, including the RBC, haematocrit and haemoglobin concentration were significantly reduced in coinfected chicks. In agreement with the changes observed in haematological features, the mortality among coinfected chicks was higher compared with animals with single infections. Clinical analysis indicated moderate changes related to different organs size (bursa of Fabricius, heart and liver) in coinfected birds. The experimental coinfection of SPF chickens with P. juxtanucleare and CAV may represent a research tool for the study of avian malaria after CAV immunosuppression, enabling measurement of the impacts caused by different pathogens during malarial infection.

Why has demand for platelet components increased? A review.  


Platelet transfusions are used in clinical practice to prevent and treat haemorrhage in thrombocytopenic patients or patients with severe platelet dysfunction. In the UK, and abroad there has been a recent rise in platelet component demand. The three largest patient groups that use platelet components are patients with haematological malignancies (up to 67%), patients receiving cardiac surgery (up to 10%) and patients receiving intensive care (up to 8%). This review has explored some of the factors that may explain this recent trend within these three main groups. These factors include a rise in the general population, an ageing population, an increase in the incidence and prevalence of haematological malignancies, and changes in the management of patients with haematological malignancies. However, the only data available that can be correlated directly with national component data are the size of the total population. There is no evidence to support the premise that use of platelet components in patients receiving cardiac surgery or intensive care treatment is rising over and above the general rise in the population, but the data are sparse.

Aplastic anaemia: an analysis of 174 patients.  

PubMed Central

The authors summarize their experience with 174 patients with aplastic anaemia (AA) with particular reference to course, prognostic factors, conversion to other blood disorders, treatment and outcome. Aplastic anaemia was defined as pancytopenia and a hypocellular marrow at some time during the illness. Seven patients terminated with acute leukaemia, 8 developed haematological features of sideroblastic anaemia and 5 showed a red cell membrane defect commonly found in paroxysmal noctural haemoglobinuria. Complete recovery occurred in only 4 patients; 70 others showed a partial remission with some residual haematological abnormality in peripheral blood. Eighteen of these had spontaneous remission. Remission was brief in 27 patients who died; only 32 patients remained in partial remission. Twenty-five per cent. of the patients with AA run an acute course and die within 6 months of the time of diagnosis. The remainder run a subacute or chronic course, punctuated in some cases by a transient remission, but in others by a conversion to other related haematological disorders. An acute course is suggested by a rapid onset of symptoms, a falling neutrophil count, a haemoglobin level less than 5 g/dl and a very low platelet count. A chronic course is likely in those patients who have a slow onset of symptoms, a stable neutrophil count and a Hb level in excess of 5 g/dl. The authors' experience shows that the disease runs either of the 2 courses irrespective of the supportive therapy. PMID:7443591

Imatinib 800 mg daily induces deeper molecular responses than imatinib 400 mg daily: results of SWOG S0325, an intergroup randomized PHASE II trial in newly diagnosed chronic phase chronic myeloid leukaemia.  


The standard dose of imatinib for newly diagnosed patients with chronic phase chronic myeloid leukaemia (CP-CML) is 400 mg daily (IM400), but the optimal dose is unknown. This randomized phase II study compared the rates of molecular, haematological and cytogenetic response to IM400 vs. imatinib 400 mg twice daily (IM800) in 153 adult patients with CP-CML. Dose adjustments for toxicity were flexible to maximize retention on study. Molecular response (MR) at 12 months was deeper in the IM800 arm (4-log reduction of BCR-ABL1 mRNA: 25% vs. 10% of patients, P = 0·038; 3-log reduction: 53% vs. 35%, P = 0·049). During the first 12 months BCR-ABL1 levels in the IM800 arm were an average 2·9-fold lower than in the IM400 arm (P = 0·010). Complete haematological response was similar, but complete cytogenetic response was higher with IM800 (85% vs. 67%, P = 0·040). Grade 3-4 toxicities were more common for IM800 (58% vs. 31%, P = 0·0007), and were most commonly haematological. Few patients have relapsed, progressed or died, but both progression-free (P = 0·048) and relapse-free (P = 0·031) survival were superior for IM800. In newly diagnosed CP-CML patients, IM800 induced deeper MRs than IM400, with a trend for improved progression-free and overall survival, but was associated with more severe toxicity. PMID:24383843

No Evidence of Dehydration with Moderate Daily Coffee Intake: A Counterbalanced Cross-Over Study in a Free-Living Population  

PubMed Central

It is often suggested that coffee causes dehydration and its consumption should be avoided or significantly reduced to maintain fluid balance. The aim of this study was to directly compare the effects of coffee consumption against water ingestion across a range of validated hydration assessment techniques. In a counterbalanced cross-over design, 50 male coffee drinkers (habitually consuming 3–6 cups per day) participated in two trials, each lasting three consecutive days. In addition to controlled physical activity, food and fluid intake, participants consumed either 4×200 mL of coffee containing 4 mg/kg caffeine (C) or water (W). Total body water (TBW) was calculated pre- and post-trial via ingestion of Deuterium Oxide. Urinary and haematological hydration markers were recorded daily in addition to nude body mass measurement (BM). Plasma was analysed for caffeine to confirm compliance. There were no significant changes in TBW from beginning to end of either trial and no differences between trials (51.5±1.4 vs. 51.4±1.3 kg, for C and W, respectively). No differences were observed between trials across any haematological markers or in 24 h urine volume (2409±660 vs. 2428±669 mL, for C and W, respectively), USG, osmolality or creatinine. Mean urinary Na+ excretion was higher in C than W (p?=?0.02). No significant differences in BM were found between conditions, although a small progressive daily fall was observed within both trials (0.4±0.5 kg; p<0.05). Our data show that there were no significant differences across a wide range of haematological and urinary markers of hydration status between trials. These data suggest that coffee, when consumed in moderation by caffeine habituated males provides similar hydrating qualities to water. PMID:24416202

Guidelines for surveillance of individuals with constitutional mismatch repair-deficiency proposed by the European Consortium "Care for CMMR-D" (C4CMMR-D).  


Lynch syndrome (LS) is an autosomal dominant disorder caused by a defect in one of the DNA mismatch repair genes: MLH1, MSH2, MSH6 and PMS2. In the last 15 years, an increasing number of patients have been described with biallelic mismatch repair gene mutations causing a syndrome referred to as 'constitutional mismatch repair-deficiency' (CMMR-D). The spectrum of cancers observed in this syndrome differs from that found in LS, as about half develop brain tumours, around half develop digestive tract cancers and a third develop haematological malignancies. Brain tumours and haematological malignancies are mainly diagnosed in the first decade of life, and colorectal cancer (CRC) and small bowel cancer in the second and third decades of life. Surveillance for CRC in patients with LS is very effective. Therefore, an important question is whether surveillance for the most common CMMR-D-associated cancers will also be effective. Recently, a new European consortium was established with the aim of improving care for patients with CMMR-D. At a workshop of this group held in Paris in June 2013, one of the issues addressed was the development of surveillance guidelines. In 1968, criteria were proposed by WHO that should be met prior to the implementation of screening programmes. These criteria were used to assess surveillance in CMMR-D. The evaluation showed that surveillance for CRC is the only part of the programme that largely complies with the WHO criteria. The values of all other suggested screening protocols are unknown. In particular, it is questionable whether surveillance for haematological malignancies improves the already favourable outcome for patients with these tumours. Based on the available knowledge and the discussions at the workshop, the European consortium proposed a surveillance protocol. Prospective collection of all results of the surveillance is needed to evaluate the effectiveness of the programme. PMID:24556086

ESCMID and ECMM joint clinical guidelines for the diagnosis and management of mucormycosis 2013.  


These European Society for Clinical Microbiology and Infectious Diseases and European Confederation of Medical Mycology Joint Clinical Guidelines focus on the diagnosis and management of mucormycosis. Only a few of the numerous recommendations can be summarized here. To diagnose mucormycosis, direct microscopy preferably using optical brighteners, histopathology and culture are strongly recommended. Pathogen identification to species level by molecular methods and susceptibility testing are strongly recommended to establish epidemiological knowledge. The recommendation for guiding treatment based on MICs is supported only marginally. Imaging is strongly recommended to determine the extent of disease. To differentiate mucormycosis from aspergillosis in haematological malignancy and stem cell transplantation recipients, identification of the reverse halo sign on computed tomography is advised with moderate strength. For adults and children we strongly recommend surgical debridement in addition to immediate first-line antifungal treatment with liposomal or lipid-complex amphotericin B with a minimum dose of 5 mg/kg/day. Amphotericin B deoxycholate is better avoided because of severe adverse effects. For salvage treatment we strongly recommend posaconazole 4×200 mg/day. Reversal of predisposing conditions is strongly recommended, i.e. using granulocyte colony-stimulating factor in haematological patients with ongoing neutropenia, controlling hyperglycaemia and ketoacidosis in diabetic patients, and limiting glucocorticosteroids to the minimum dose required. We recommend against using deferasirox in haematological patients outside clinical trials, and marginally support a recommendation for deferasirox in diabetic patients. Hyperbaric oxygen is supported with marginal strength only. Finally, we strongly recommend continuing treatment until complete response demonstrated on imaging and permanent reversal of predisposing factors. PMID:24479848

Interpretation of the full blood count in systemic disease--a guide for the physician.  


The full blood count (FBC) is perhaps the single most common investigation performed in medical patients. It has the potential, when interpreted carefully and in relation to the clinical history, to provide very useful information to assist in diagnosis and management. Clinicians are often alerted to the presence of a primary haematological disorder by abnormalities in the FBC. For the purpose of this review these diseases will not be discussed in detail but the reader will be alerted to pointers which might indicate primary blood disorders throughout the text. The haematology laboratory in large teaching hospitals will often provide up to 1,500 automated FBC analyses each day. These are individually checked for 'flags' provided by the analyser which indicate values outside the normal range. It is clearly essential that clinical information is provided with the request as this will influence how the result is handled by scientific and medical staff. Furthermore, significant abnormalities will generate a blood film request and the report will be most useful when interpreted in light of the patient's working diagnosis. In cases where a diagnosis is not yet known, even brief information on presentation, for example 'collapse with hypotension', 'fever on return to UK', 'weight loss and anorexia', can all be important and help the lab provide clinicians with guidance. This short review aims to provide physicians with a workable guide to the interpretation of some of the commoner findings in the full blood count. Some of these will be very familiar to you but some will not. This review is not meant to be exhaustive as the rare minutiae will obscure the essential core material. Your haematology colleagues are always happy to help and available for assistance in difficult or problematic cases. I have not specified normal ranges in relation to each entity as these will be defined by your local laboratory. PMID:24995446

Clinical and virological factors associated with hepatitis B virus reactivation in HBsAg-negative and anti-HBc antibodies-positive patients undergoing chemotherapy and/or autologous stem cell transplantation for cancer.  


We studied clinical outcome and clinico-virological factors associated with hepatitis B virus reactivation (HBV-R) following cancer treatment in hepatitis B virus surface antigen (HBsAg)-negative/anti-hepatitis B core antibodies (anti-HBcAb)-positive patients. Between 11/2003 and 12/2005, HBV-R occurred in 7/84 HBsAg-negative/anti-HBcAb-positive patients treated for haematological or solid cancer. Virological factors including HBV genotype, core promoter, precore, and HBsAg genotypic and amino acid (aa) patterns were studied. Patients presenting with reactivation were men, had an hepatitis B virus surface antibody (HBsAb) titre <100 IU/L and underwent >1 line of chemotherapy (CT) significantly more frequently than controls. All were treated for haematological cancer, 3/7 received haematopoietic stem cell transplantation (HSCT), and 4/7 received rituximab. Using multivariate analysis, receiving >1 line of CT was an independent risk factor for HBV-R. Fatal outcome occurred in 3/7 patients (despite lamivudine therapy in two), whereas 2/4 survivors had an HBsAg seroconversion. HBV-R involved non-A HBV genotypes and core promoter and/or precore HBV mutants in all cases. Mutations known to impair HBsAg antigenicity were detected in HBV DNA from all seven patients. HBV DNA could be retrospectively detected in two patients prior cancer treatment and despite HBsAg negativity. HBV-R is a concern in HBsAg-negative/anti-HBcAb-positive patients undergoing cancer therapy, especially in males presenting with haematological cancer, a low anti-HBsAb titre and more than one chemotherapeutic agent. HBV DNA testing is mandatory to improve diagnosis and management of HBV-R in these patients. The role of specific therapies such as rituximab or HSCT as well as of HBV aa variability deserves further studies. PMID:20002298

Non-Hodgkin's lymphomata: clinical and immunological data in relation to histology.  

PubMed Central

Two hundred and forty-four previously untreated patients seen since 1964 in the department of haematology at Saint-Louis hospital were analysed. Clinical data included results of initial work-up and prognosis evaluated by survival rate matched with principal variables: age, sex, histopathology, staging, incidence of clinical and biological systemic symptoms. Immunological data included results of systematic studies made in each category of non-Hodgkin's lymphomata. Hyperbasophilic lymphoma, a special group recently characterized, is discussed.

Serum cryoglobulins are found in a wide spectrum of disorders but are often transient and without clinical implications. Monoclonal cryoglobulins are usually associated with haematological disorders, whereas mixed cryoglobulins are found in many infectious and systemic disorders. So called essential mixed cryoglobulinaemia shows a striking association with hepatitis C virus (HCV) infection (> 90%). It is a systemic vasculitis (leucocytoclastic vasculitis) with cutaneous and multiple visceral organ involvement. Chronic HCV infection can lead to a constellation of autoimmune and neoplastic disorders. In this review, the aetiology, diagnosis, disease heterogeneity, and treatment of cryoglobulinaemia are discussed. PMID:11825916

Metastatic superscan on 99mTc-MDP bone scintigraphy in a case of carcinoma colon: Common finding but rare etiology  

PubMed Central

Bone scintigraphy in which there is excessive skeletal radioisotope uptake in relation to soft tissues along with absent or faint activity in the genitourinary tract is known as a ‘superscan’. Prostate cancer is the most common malignancy associated with superscan along with others such as lung cancer, breast cancer and haematological malignancies. Here we present the case of a 41 year old woman with carcinoma colon with metastatic superscan on 99mTc-MDP bone scintigraphy, a very rare cause for metastatic superscan. PMID:25210281

Haemolytic anaemia secondary to arsenic poisoning: a case report  

PubMed Central

We report the case of a 56-year-old white man who presented at the Emergency Department for evaluation of dark-red urine. Rapid development of acute renal failure and haemolytic anaemia initially elicited the hypothesis of a haemolytic-uremic syndrome. A previous exposure to a gas mixture containing arsenic and copper was later recognized as the probable aetiology while other differential diagnoses were excluded. Chelating treatment was promptly initiated before laboratorial confirmation of arsenic and copper poisoning. Renal and haematological recovery was gradually observed and the patient survived with no sequelae. PMID:19918480

A cross sectional study of employees with potential occupational exposure to ethylene oxide.  

PubMed Central

A cross sectional study was conducted on 84 employees potentially exposed to ethylene oxide (EO) to determine whether they had a higher prevalence of abnormalities of the haematopoietic, hepatic, or renal systems than a control group individually matched on age, hire date, race, smoking habits, alcohol history, and date of examination. Potential exposures were estimated to be generally below the current threshold limit value of 10 ppm, with most below 1 ppm. Results of the haematological and biochemical studies were similar in the two groups. A statistically significant (p = 0.035) increase in the prevalence of proteinuria was noted among the EO group which warrants further investigation. PMID:6333892

Subchronic toxicity of vomitoxin in Sprague-Dawley rats.  


Purified vomitoxin was incorporated into the diet at a level of 20 ppm and fed to male Sprague-Dawley rats ad lib. for 90 days. Few clinical signs of toxicity were observed. Rats in the vomitoxin treatment group were less efficient in converting feed into body mass, but there was no feed refusal. Terminal body weight was reduced in the vomitoxin treatment group. There were no statistically significant effects on serum enzyme levels, haematological parameters or tissue lesions, or on liver detoxification systems, as reflected in levels of microsomal cytochrome P-450 or in glutathione S-transferase activity.

Partial priapism.  


With only 34 prior cases in world literature, partial priapism (PP), also called partial segmental thrombosis of the corpus cavernosum, is a rare urological condition. The aetiology and treatment of PP is still unclear, but bicycle riding, trauma, drug usage, sexual intercourse, haematological diseases and ?-blockers have been associated with PP. In this case report and world literature review, we describe the case of a 50-year-old man suffering from PP after ingesting 100 mg of sildenafil. The patient was treated with a surgical incision for corpus cavernosum and clot evacuation, as a conservative treatment of PP was not feasible due to severe pain and unresponsiveness to analgesics.

Iliopsoas abscess with iliac and femoral vein thrombosis in an adult Siberian husky.  


A nine-year-old, male Siberian husky was presented with fever, decreased appetite and activity, non-weightbearing lameness, and oedematous swelling of the right inguinal and preputial area and the right hindlimb. An abscess within the right iliopsoas muscle, with severe thrombosis of the iliac and femoral vein, was diagnosed by haematology and diagnostic imaging. The abscess and adjoining lymph node were removed surgically through a median coellotomy. The isolated pathogen was Staphylococcus intermedius. Clinical signs resolved completely after surgery. Antimicrobial therapy was continued for four weeks. Within the follow-up period of six months, no recurrence of the clinical signs was detected. PMID:14984156

Autoimmunity in chronic lymphocytic leukaemia.  

PubMed Central

The prevalence of autoantibodies in B cell chronic lymphocytic leukaemia (B-CLL) was investigated. A lower prevalence of autoimmune haemolytic anaemia than that found in other series was found: large numbers of non-progressive stage A disease cases were included, in which the prevalence of autoimmune haemolytic anaemia is low. Non-haematological autoantibodies were no commoner than in age matched controls. Whatever explanation is offered for autoimmune phenomena in B-CLL it must take account of the fact that those phenomena are virtually confined to autoantibodies against the formed elements of the blood.

Teicoplanin-induced leucopenia with immediate resolution after administration of G-CSF.  


Teicoplanin is used in a wide range of clinical settings, owing to its wide antiGram positive bacterial activity. Although it is generally well tolerated, adverse reactions such as fever and rash are well recognised. Haematological sequelae have been rarely reported. This case report describes the development of teicoplanin-induced leucopenia in a patient with infective endocarditis. A short course of lenograstim, a recombinant granulocyte colony-stimulating factor (G-CSF) reverted biochemical abnormalities. To the authors' best knowledge, this is the first documented example of implementation of G-CSF in such a clinical setting. PMID:22891005

[Pancytopenia, haemolytic anaemia, schistocytes: a frequent pathology mimicking a rare and serious pathology].  


A 83 years old woman presents to our hospital with fatigue and dyspnea since 2 weeks, followed by a painless icterus. On laboratory we discover a pancytopenia with severe haemolytic anaemia, thrombopenia and schistocytosis. This association suggest a thrombotic microangiopathy. In the presence of macrocytes, hypersegmented neutrophils and a low reticulocytes count, a vitamin screening was performed witch leads to the discovery of a vitamin B12 and folic acid deficiency. After initiation of a vitamin therapy we observe a reticulocytic crisis and thereafter the normalisation of the haematological parameters. PMID:15697148

An Ashkenazi Jewish woman presenting with favism  

PubMed Central

The case of a 44 year old Ashkenazi Jewish woman of Russian origin who presented with a typical clinical and haematological picture of favism is reported. There was initial difficulty in confirming glucose-6-phosphate dehydrogenase (G6PD) deficiency because the enzyme concentrations were normal at presentation, but later fell to a concentration compatible with heterozygosity for the Mediterranean type of G6PD deficiency. The diagnosis was also later confirmed by gene analysis. The reasons for the difficulties in the initial confirmation of the diagnosis and the normal G6PD enzyme activity at presentation are discussed. PMID:15735168

Radioimmunotherapy: a brief overview  

PubMed Central

With the advent of biotechnological advances and knowledge of molecular and cellular biology, radioimmunotherapy (RIT) has become a highly promising oncologic therapeutic modality with established clinically efficacy, particularly in non-Hodgkin’s lymphomas. This paper provides a short survey of the basic science of RIT and the various monoclonal antibodies and radionuclides used. A brief review of the published literature on the clinical applications of radioimmunotherapy, particularly in non-Hodgkin’s lymphoma, is provided. New research data indicate many potential areas of development of this modality, including haematological and solid-organ radioimmunotherapy as well as new radionuclidic approaches and clinical protocols.

Pernicious anaemia presenting as catatonia without signs of anaemia or macrocytosis.  


Pernicious anaemia can present with psychiatric symptoms before haematological or neurological manifestations appear. We describe a young woman who presented with insidious onset catatonia without evidence of psychosis or depression. Blood count and mean cell volume were normal and neurological findings were equivocal. Low B(12) levels and intrinsic factor antibodies were found only by chance when they were included in a battery of further investigations. B(12) replacement was followed by prompt improvement. This case provides an argument for wider screening for B(12) deficiency in certain individuals with psychiatric disorders. PMID:20807971

Haemoglobin Warwickshire (beta 5 [A2] Pro----Arg). A possible 'fine tuning' of 2,3-DPG affinity by beta 5 Pro.  


The blood of a 67-year-old Scotsman who was admitted to hospital with an abdominal carcinoma showed an abnormal red cell lysis in the oxidase channel of the Technicon H6000 analyser. This is seen regularly with Hb C and sometimes with Hb S and on further investigation a new haemoglobin variant--Hb Warwickshire--was found. When the family was examined, other examples were revealed. The haematological parameters were normal. Hb Warwickshire is mildly unstable and whilst in the absence of phosphates its oxygen dissociation does not differ from that of Hb A, a small fall of oxygen affinity is noted when phosphates are present.

[Hematological abnormalities in patients with systemic lupus erythematosus].  


Haematological abnormalities are frequently encountered in patients with systemic lupus erythematosus (SLE). Anaemia is the most common hematological abnormality in SLE, it is multifactorial. The most common form of anaemia is that of chronic disease, and it is relate with inflammatory cytokines. Other tips of anaemia are: iron deficiency anaemia, autoimmune haemolytic anaemia, pure red cell aplasia. Leucopenia is related to neutropenia and/or lymphopenia. Thrombocytopenia is common, autoimmune and associated with a decreased survival. The presence of antiphospholipid antibodies increase risk of thrombosis in patients with SLE. PMID:12481500

Successful pregnancy following aplastic anaemia.  

PubMed Central

Pregnancy following idiopathic aplastic anaemia is rare and is difficult to manage because of life-threatening episodes of bleeding and infections. Only a handful of cases has been reported in the literature. The pregnancies were unsuccessful in the majority. The present report describes a patient with moderately severe idiopathic aplastic anaemia who was managed with intensive haematological support leading to delivery of a healthy infant by caesarean section. Despite platelet transfusion refractoriness as a result of transfusions prior to pregnancy, adequate platelet transfusions prevented excessive bleeding. The literature is reviewed and management with platelet transfusions is discussed. PMID:8545293

An apparent flea-allergy dermatitis in kids and lambs.  


Heavy infestation of lambs in two herds and kids in one herd with the cat flea, Ctenocephalides felis felis, accompanied by severe anaemia, eosinophilia and exudative dermatitis, is described. Flea infestation was more widespread during the summer months, when optimal climatic conditions for flea development prevail. The clinical and histological findings are discussed in the light of the pertinent literature. Recovery of the affected animals and normalization of the haematological values were observed after the insecticide treatment. Flea-allergic dermatitis is apparently the cause of the skin lesions in the lambs and kids. PMID:9360467

Recombinant erythropoietin in clinical practice  

PubMed Central

The introduction of recombinant human erythropoietin (RHuEPO) has revolutionised the treatment of patients with anaemia of chronic renal disease. Clinical studies have demonstrated that RHuEPO is also useful in various non-uraemic conditions including haematological and oncological disorders, prematurity, HIV infection, and perioperative therapies. Besides highlighting both the historical and functional aspects of RHuEPO, this review discusses the applications of RHuEPO in clinical practice and the potential problems of RHuEPO treatment.

Recommendations for diagnosis and management of metformin-induced vitamin B12 (Cbl) deficiency.  


Metformin treatment is a known pharmacological cause of vitamin B12 (Cbl) deficiency with controversial responsible mechanisms. A possible diagnosis of this deficiency is based mainly on the combination of patient's medical history (usually long-term metformin use), clinical examination (possible neuropsychiatric symptoms and signs), laboratory studies which confirm a Cbl deficiency (haematological abnormalities, low serum Cbl levels, elevated serum total homocysteine and methylmalonic acid levels), and exclusion other causes of Cbl deficiency (as pernicious anaemia, food-cobalamin malabsorption syndrome, other drugs, etc.). In our review, recommendations for diagnosis and management of metformin-induced Cbl deficiency (MICD) in diabetic patients based on medical bibliography are presented and discussed. PMID:22770998

Prospective study of aetiological factors in burning mouth syndrome  

PubMed Central

A prospective study of 150 consecutive patients with burning mouth syndrome and with a minimum follow up period of 18 months is reported. Factors related to dentures, to vitamin B complex deficiency, and to psychological abnormalities were found to be important, and undiagnosed diabetes mellitus, reduced salivary gland function, haematological deficiencies, candidal infection, parafunctional habits, and allergy might also play a part. Given a protocol for management which takes all these factors into account, some two thirds of patients can be cured or have their symptoms improved. PMID:3133028

[The red blood picture in male nutria in the post-natal period].  


Blood was sampled by heart puncture from healthy male coypus of ten age categories (from 1 to 300 days). The basic haematological values of the red blood picture were determined in these samples. including the erythrocyte count, haemoglobin content, haematocrit reading, mean corpuscular haemoglobin, mean corpuscular haemoglobin concentration, and mean corpuscular volume. The summarized mathematico-statistical characteristics were calculated from the values obtained in each group and the significance of differences was determined by the analysis of variance at significance levels of P = 0.01 and P = 0.05.

In Brief: (mis)splicing in disease.  


Splicing of pre-mRNAs is a crucial step in the gene expression pathway. Disruption of splicing has been linked to the pathogenesis of several human diseases and is particularly widespread in cancer. Recently, a number of mutations affecting genes of the core spliceosome machinery have been identified in haematological malignancies, yet the effect of such mutations on RNA splicing is unclear. A better understanding of how mis-splicing contributes to malignancies may provide diagnostic or prognostic information and new drug targets for therapeutic approaches. PMID:24615176

[Multiple myeloma in a Yucatan Pig].  


An 11 years old Yucatan Pig with a Multiple Myeloma in the spinal cord, the sternum and the pelvis is described. The major clinical sign was a paresis of the hind limb. The most significant haematological change was a lymphopenia. The X-ray examination and computed tomography showed typical osteolytic changes in the skeleton. The histological examination of the bone marrow showed many, moderately well-differentiated plasma cells. Based on the collected findings and the exclusion of differential diagnoses, a Multiple Myeloma was diagnosed. PMID:20135913

Subacute toxicity study of the combination of ginseng (Panax ginseng) and ashwagandha (Withania somnifera) in rats: a safety assessment.  


Ginseng (Panax ginseng) and Ashwagandha (Withania somnifera) are widely used as geriatric tonics. Both individually have not shown any toxicity on long term administration. Study was planned to assess the safety of the combination by doing subacute toxicity study in rats with 90 days oral administration using three doses. Food consumption, body weight, haematological, biochemical and histopathological parameters were studied. There was significant increase in body weight, food consumption and liver weight, and improved hematopoiesis was observed. Brain, heart, lung, liver, spleen, kidneys, stomach, testis and ovaries were normal on gross examination and histopathologically. Subacute toxicity studies in rats did not reveal any toxicity.

A favourable response to surgical intervention and hyperbaric oxygen therapy in pyoderma gangrenosum.  


Pyoderma gangrenosum (PG) is a neutrophilic dermatosis characterised with ulcerations. Inflammatory bowel diseases (ulcerative colitis and Crohn's disease) and haematologic diseases (leukaemia, preleukaemia and monoclonal gammopathy) have been reported in about 40-50% of PG patients in whom the treatment of the underlying disease is important for the improvement of the lesions. We herein report a colorectal adenocarcinoma patient with PG, who responded partially to topical treatments and systemic immunosuppressants and healed completely with the aid of surgical wound repair and hyperbaric oxygen therapy.

Inactivation of PI(3)K p110? breaks regulatory T-cell-mediated immune tolerance to cancer.  


Inhibitors against the p110? isoform of phosphoinositide-3-OH kinase (PI(3)K) have shown remarkable therapeutic efficacy in some human leukaemias. As p110? is primarily expressed in leukocytes, drugs against p110? have not been considered for the treatment of solid tumours. Here we report that p110? inactivation in mice protects against a broad range of cancers, including non-haematological solid tumours. We demonstrate that p110? inactivation in regulatory T cells unleashes CD8(+) cytotoxic T cells and induces tumour regression. Thus, p110? inhibitors can break tumour-induced immune tolerance and should be considered for wider use in oncology. PMID:24919154

Cryopreservation of Human Stem Cells for Clinical Application: A Review  

PubMed Central

Summary Stem cells have been used in a clinical setting for many years. Haematopoietic stem cells have been used for the treatment of both haematological and non-haematological disease; while more recently mesenchymal stem cells derived from bone marrow have been the subject of both laboratory and early clinical studies. Whilst these cells show both multipotency and expansion potential, they nonetheless do not form stable cell lines in culture which is likely to limit the breadth of their application in the field of regenerative medicine. Human embryonic stem cells are pluripotent cells, capable of forming stable cell lines which retain the capacity to differentiate into cells from all three germ layers. This makes them of special significance in both regenerative medicine and toxicology. Induced pluripotent stem (iPS) cells may also provide a similar breadth of utility without some of the confounding ethical issues surrounding embryonic stem cells. An essential pre-requisite to the commercial and clinical application of stem cells are suitable cryopreservation protocols for long-term storage. Whilst effective methods for cryopreservation and storage have been developed for haematopoietic and mesenchymal stem cells, embryonic cells and iPS cells have proved more refractory. This paper reviews the current state of cryopreservation as it pertains to stem cells and in particular the embryonic and iPS cell. PMID:21566712

Molecular Prevalence of Babesia bigemina and Trypanosoma evansi in Dairy Animals from Punjab, India, by Duplex PCR: A Step Forward to the Detection and Management of Concurrent Latent Infections  

PubMed Central

Specific duplex polymerase chain reaction (PCR) was employed on 411 (386 cattle and 25 buffaloes) blood samples of dairy animals from 9 districts of Punjab, India, for simultaneous detection of Babesia bigemina and Trypanosoma evansi. The results were compared and correlated with conventional Giemsa stained thin blood smear (GSTBS) examination and haematological alterations to know the clinical status and pathogenicity of infections. The Bg3/Bg4 and TR3/TR4 primers were used in duplex PCR for B. bigemina and T. evansi amplified products of 689?bp and 257?bp, respectively. The overall prevalence by duplex PCR was found to be 36.49, 2.43, and 3.41% for T. evansi, B. bigemina, and dual infection, respectively. A more significant difference was observed for dual infection status (P ? 0.005) as compared to T. evansi (P ? 0.05) and B. bigemina (P ? 0.01) among various districts under study. A very low prevalence of T. evansi (0.73%) and B. bigemina (0.48%) was seen by GSTBS. The highly sensitive, specific, and cost-effective duplex PCR was able to detect latent T. evansi and B. bigemina infection in cattle and buffaloes. Haematological evaluation revealed marked pathology in B. bigemina infected group and in dual infected group in contrast to that infected with T. evansi alone. PMID:24069605

Bone healing performance of electrophoretically deposited apatite-wollastonite/chitosan coating on titanium implants in rabbit tibiae.  


Bone healing of tibial defect in rabbit model was used to evaluate a composite coating of apatite-wollastonite/chitosan on titanium implant. This coating has been developed to overcome the shortcomings, such as implant loosening and lack of adherence, of uncoated titanium implant. An electrophoretic deposition technique was used to coat apatite-wollastonite/chitosan on titanium implants. The present study was designed to evaluate the bone response of coated as compared to uncoated titanium implants in an animal model. After an implantation period of 14 (group A), 21 (group B), 35 (group C) and 42 days (group D), the bone-implant interfaces and defect site healing was evaluated using radiography, scintigraphy, histopathology, fluorescence labeling and haematology. Radiography of defect sites treated with coated implants suggested expedited healing. Scintigraphy of coated implant sites indicated faster bone metabolism than uncoated implant sites. Histopathological examination and fluorescence labeling of bone from coated implant sites revealed higher osteoblastic activity and faster mineralization. Faster bone healing in the case of coated implant sites is attributed to higher cell adhesion on electrostatically charged chitosan surfaces and apatite-wollastonite-assisted mineralization at bone-implant interfaces. Haematological studies showed no significant differences in haemoglobin, total erythrocyte and leukocyte counts, done using one way-ANOVA, during the entire study period. Our results show that AW/chitosan-coated implants have the advantages of faster bone healing, increased mechanical strength and good bone-implant bonding. PMID:19621346

Phase II trial of sagopilone, a novel epothilone analog in metastatic melanoma  

PubMed Central

Background: Sagopilone is a novel fully synthetic epothilone with promising preclinical activity and a favourable toxicity profile in phase I testing. Methods: A phase II pharmacokinetic and efficacy trial was conducted in patients with metastatic melanoma. Patients had measurable disease, Eastern Cooperative Oncology Group performance status 0–2, adequate haematological, and organ function, with up to 2 previous chemotherapy and any previous immunotherapy regimens. Sagopilone, 16?mg?m?2, was administered intravenously over 3?h every 21 days until progression or unacceptable toxicity. Results: Thirty-five patients were treated. Sagopilone showed multi-exponential kinetics with a mean terminal half-life of 64?h and a volume of distribution of 4361?l?m?2 indicating extensive tissue/tubulin binding. Only grade 2 or lower toxicity was observed: these included sensory neuropathy (66%), leukopenia (46%), fatigue (34%), and neutropenia (31%). The objective response rate was 11.4% (one confirmed complete response, two confirmed partial responses, and one unconfirmed partial response). Stable disease for at least 12 weeks was seen in an additional eight patients (clinical benefit rate 36.4%). Conclusion: Sagopilone was well tolerated with mild haematological toxicity and sensory neuropathy. Unlike other epothilones, it shows activity against melanoma even in pretreated patients. Further clinical testing is warranted. PMID:20924376

Inhibition of Ehrlich ascites carcinoma by Manilkara zapota L. stem bark in Swiss albino mice  

PubMed Central

Objective To evaluate the antitumor activity of Manilkara zapota (M. zapota) L. stem bark against Ehrlich ascites carcinoma (EAC) in Swiss albino mice. Methods The in vivo antitumour activity of the ethyl acetate extract of stem bark of M. zapota L. (EASM) was evaluated at 50, 100 and 200 mg/kg bw against EAC using mean survival time. After administration of the extract of M. zapota, viable EAC cell count and body weight in the EAC tumour hosts were observed. The animal was also observed for improvement in the haematological parameters (e.g., heamoglobin content, red and white blood cells count and differential cell count) after EASM treatment. Results Intraperitoneal administration of EASM reduced viable EAC cells, increased the survival time, and restored altered haematological parameters. Significant efficacy was observed for EASM at 100 mg/kg dose (P<0.05). Conclusions It can be concluded that the ethyl acetate extract of stem bark of M. zapota L. possesses significant antitumour activity. PMID:23569811

Response to androgen therapy in patients with dyskeratosis congenita.  


Dyskeratosis congenita (DC) is an inherited bone marrow failure syndrome and telomere biology disorder characterized by dysplastic nails, reticular skin pigmentation and oral leucoplakia. Androgens are a standard therapeutic option for bone marrow failure in those patients with DC who are unable to undergo haematopoietic stem cell transplantation, but there are no systematic data on its use in those patients. We evaluated haematological response and side effects of androgen therapy in 16 patients with DC in our observational cohort study. Untreated DC patients served as controls. Seventy percent of treated DC patients had a haematological response with red blood cell and/or platelet transfusion independence. The expected age-related decline in telomere length was noted in androgen-treated patients. All treated DC patients had at least one significant lipid abnormality. Additional treatment-related findings included a significant decrease in thyroid binding globulin, accelerated growth in pre-pubertal children and splenic peliosis in two patients. Liver enzymes were elevated in both androgen-treated and untreated patients, suggesting underlying liver involvement in DC. This study suggests that androgen therapy can be effectively used to treat bone marrow failure in DC, but that side effects need to be closely monitored. PMID:24666134

Subclinical anaplasmosis in camel (Camelus dromedarius) and its successful therapeutic management.  


On the Indian sub continent, dromedarian camel -'the ship of the desert' is an important constituent of the socio economic life style of nomadic owners in the semi arid to arid ecosystems. The animal suffers from a few parasitic diseases viz. surra, coccidiosis, sarcocystis, gastro intestinal concurrent metazoan infections, mange, nasal bots and ticks infestations. However, anaplasmosis in camel has not been reported so far from the Indian subcontinent. Systematic investigations of a 7 year male Jaisalmeri camel, with a clinical history of dullness, progressive loss of condition and stamina revealed subclinical Anaplasma marginale infection. The animal had depressed haematological indices, dry and constipated bowels, pale and icteric conjunctiva suggestive of anaemia. The animal positively responded to the specific integrated therapy. Reexamination of the animal on day 21 post-therapy revealed depressed haematological indices restored to normal levels and the erythrocytes were free from the pathogen. Neglected attention, poor and/or underreporting of camel diseases vis-a-vis economic significance of the versatile animal has been discussed. This appears to be the pioneer documentation of anaplasmosis in camels from Indian subcontinent. PMID:24808644

Screening for mutations of Bcl10 in leukaemia.  


The Bcl10 gene was identified through characterization of the t(1;14)(p22;q32) associated with mucosa-associated lymphoid tissue (MALT) lymphoma. Bcl10 is implicated in the regulation of apoptosis and has been reported to be mutated in other subtypes of non-Hodgkin's B-cell lymphoma (B-NHL) and leukaemic cell lines, raising the possibility that its deregulation could be implicated in other forms of haematological malignancy. We screened 226 cases, including 123 acute myeloid leukaemia (AML), 50 acute lymphoblastic leukaemia (ALL), 20 chronic myeloid leukaemia (CML), 10 chronic lymphocytic leukaemia-prolymphocytic leukaemia (CLL/PLL) and 23 cases with 1p abnormalities, for Bcl10 mutations by reverse transcription polymerase chain reaction-single-stranded conformation polymorphism (RT-PCR/SSCP). Three known polymorphisms and two common splice variants were identified; however, no mutations were detected. One splice variant led to a 33-bp in frame deletion, whereas the other caused a 16-bp deletion predicting C-terminal truncation of Bcl10. However, both splice variants were also detected in normal bone marrow, suggesting that they are unlikely to be of pathogenetic significance. Furthermore, Southern blot analysis revealed no rearrangements of Bcl10 among 16 ALL and 11 cases of haematological malignancy with 1p abnormalities. Our results suggest that mutation of the Bcl10 gene as a mechanism of tumorigenesis is not associated with leukaemia. PMID:10886211

Treatment and outcomes of invasive fusariosis: review of 65 cases from the PATH Alliance(®) registry.  


Invasive Fusarium infections occur in immunosuppressed patients, especially those with haematological malignancies. We conducted a descriptive analysis of data from patients with invasive fusariosis identified in the Prospective Antifungal Therapy Alliance registry, which collected data on invasive fungal infections in the United States and Canada from 2004 to 2008. In this series of 65 patients with proven (83.1%) and probable (16.9%) invasive fusariosis, the most common underlying condition was haematological malignancy, in which neutropenia and corticosteroid usage frequently occurred. Seven patients with invasive Fusarium infections had cross-reactive galactomannan assay results. The survival rate for all patients at 90 days was 44%, which was an improvement compared with historical data. Disseminated disease occurred frequently (35.4%), and patients with and without disseminated disease had survival rates of 33% and 50%, respectively. Posaconazole and voriconazole were the most frequently employed therapies and may be linked to the improved survival rate observed in this patient series. In summary, patients with invasive Fusarium infections continue to have high fatality rates, especially those with disseminated disease. Fusarium infections should be strongly considered in the absence of Aspergillus isolation in patients at high risk of mould infections with positive galactomannan assay test results. PMID:24943384

Toxic effects of malathion in carp, Cyprinus carpio carpio: protective role of lycopene.  


The present study was carried out in order to investigate the potential protective effects of lycopene against malathion-induced toxicity in carp. The fish were exposed to sublethal concentrations of malathion (0.5 and 1mgL(-1)) for 14 days, and lycopene (10mgkg(-1) of fish weight) was simultaneously administered. Samples of the blood and tissue (liver, kidneys, and gills) were collected at the end of the experimental period and their haematological profiles [red blood cell (RBC) counts, haemoglobin (Hb) concentrations, haematocrit (Ht) levels, and erythrocyte indices, including the mean corpuscular volume (MCV), the mean corpuscular haemoglobin (MCH) and the mean corpuscular haemoglobin concentration (MCHC)], immune responses [white blood cell (WBC) counts, oxidative radical production (nitroblue tetrazolium (NBT) activity), total plasma protein (TP) and total immunoglobulin (TI) levels and phagocytic activities (PA)] and oxidant/antioxidant statuses [malondialdehyde (MDA) levels, superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GSH-Px) activities, and reduced glutathione (GSH) concentrations] were analysed. The findings of the present study demonstrated that the exposure of carp to malathion resulted in alterations in the haematological profiles and immune responses, and lead to increased reactive oxygen species formation, resulting in oxidative damage and inhibition of the antioxidant capacities. However, the administration of lycopene prevented malathion-induced toxic effects. PMID:23932509

Population-based surveillance for scedosporiosis in Australia: epidemiology, disease manifestations and emergence of Scedosporium aurantiacum infection.  


Australia-wide population-based surveillance for scedosporiosis identified 180 cases, with 118 (65.6%) cases of colonization and 62 (34.4%) cases of infection. Predisposing factors for isolation of Scedosporium spp. included chronic lung disease in 37.8% and malignancy in 21.7% of cases. Predictors of invasive disease (n=62) included haematological stem cell transplantation (n=7), leukaemia (n=16) and diabetes mellitus (n=8). Of 183 phenotypically-speciated isolates, 75 (41%) were Scedosporium prolificans (risk factors: haematologic cancer (n=17), neutropaenia (n=14)) and 108 (59%) had Scedosporium apiospermum/Pseudallescheria boydii phenotype [risk factor: diabetes (n=15)]. Scedosporium prolificans (p 0.01) and leukaemia (p 0.03) independently predicted death. Epidemiological and antifungal susceptibility profiles of Scedosporium aurantiacum (prevalence>or=15.8%) and S. apiospermum were similar. No patient with S. aurantiacum infection (n=6) died. This is the first description of clinical features associated with S. aurantiacum. PMID:19549223

[Benign acute childhood myositis (BACM)--cases report].  


Benign acute childhood myositis (BACM) is characterised by sudden calf pain and inability to walk. We analyzed the characteristics of seven boys and two girls with BACM treated in the Pediatric Department from April 2005 to March 2009. The mean age at onset of symptoms was 7 +/- 2 years. Two boys were hospitalized twice for BACM. All cases occurred in winter or spring. 7 out of all admissions were clustered together in one week long periods. Patients demonstrated prodromal symptoms of flu-like illness followed by the sudden onset of difficulty in walking. One girl additionally complained of a painful right hip. Four patients received inosine pranobex for prodromal viral infection before the clinical onset of myositis. In all cases, creatine phosphokinase (CPK; the highest value at 8988 U/l) and aspartate aminotransferase (AST; the highest value at 329 U/l) values were elevated. The serum concentration of myoglobin was elevated in five out of six tested patients (the highest value at 2172 microg/l). The following haematological abnormalities were detected: leucocytopenia (the lowest WBC 1.35 x 10(3)/microl), neutropenia, and trombocytopenia. All patients made a rapid recovery within 1 to 5 days. Pediatricians and emergency medicine specialists must be aware that BACM is a self-limiting disorder with the acute onset of inability to walk, elevated CPK and AST levels, and transient haematological abnormalities. There is no sufficient data from clinical reports on immunostimulant use before the onset of BACM. PMID:19856879

Biochemical toxicology of argemone oil. IV. Short-term oral feeding response in rats.  


Consumption of edible oils contaminated with Argemone mexicana seed oil is known to cause various clinical manifestations. In the present study, the effect of dietary intake of argemone oil on histopathological changes, haematological indices and selected marker parameters of toxicity was investigated to observe the exact sites and mode of action of argemone oil in rats. Histopathological changes in the liver showed increased fibrosis, hyperplasia of bile ducts and congestion in a few portal tracts. Lungs of argemone oil-fed animals indicated congestion and thickening of interalveolar septa. Alveolar spaces were disorganised and irregular. Kidneys showed vascular and glomerular congestion and patchy tubular lesions. At 30 days only mild congestion was noted in the myocardium. Cardiac muscle fibres showed degenerative changes at 60 days which were more marked in the auricular wall. Haematological examination showed appearance of anaemia in experimental animals. Hepatic alkaline phosphatase, alanine transaminase and aspartate transaminase activities were inhibited by 30, 29 and 29% after 30 days of argemone intake along with concomitant enhancement in serum by 27, 29 and 66%, respectively. Liver showed decrease in glutathione (32-63%) content along with significant stimulation of lipid peroxidation (49-105%) in argemone-intoxicated animals. These results suggest that liver, lungs, heart and kidneys are the target tissues of argemone oil toxicity and that membrane destruction may be a possible mode of action. PMID:2799830

Responsiveness to recombinant erythropoietin therapy in end-stage renal disease. An analysis of the predictive value of several biological measurements, including circulating erythroid progenitors.  


In end-stage renal disease (ESRD), the human recombinant erythropoietin doses required to keep haemoglobin in the target range may vary considerably between patients. Previous studies have failed to find any predictive factor of the response. We thus performed the present investigation in 30 ESRD patients to discover if the haematological response to human recombinant erythropoietin (rHuEpo) was related to the results of circulating erythroid progenitor cultures. Peripheral erythroid burst forming units (BFU-E) were cultured in a plasma clot system in the absence or in the presence of autologous serum just before starting rHuEpo therapy. The results showed a higher BFU-E number in ESRD patients than in controls and a stimulatory effect of autologous serum in both patients and controls. Comparison between culture results and haematological response yielded positive correlation between the BFU-E number and the haemoglobin increase during the first month of treatment, and negative correlation between the increase of BFU-E numbers during the first week of therapy and the rHuEpo doses required for a long-term response. We thus conclude that in ESRD patients the individual response to rHuEpo is linked to the numbers of circulating BFU-E. PMID:1317521

Effect of pre-slaughter management regarding transportation and time in lairage on certain stress parameters, carcass and meat quality characteristics in Kivircik lambs.  


Thirty Kivircik lambs were used to investigate effect of pre-slaughter treatment on certain haematological and biochemical parameters, carcass and meat quality characteristics. Lambs were divided into three treatments: 75 min transport and lairage for 18 h (TS-L18 h); 75 min transport and lairage for 30 min (TS-L30 min) and no pre-slaughter transport and lairage for 30 min (NTS). Treatment, as a main effect, did not influence haematological and biochemical parameters, but sampling time significantly affected these parameters, except total protein. Plasma cortisol concentration at exsanguination in TS-18 h, TS-30 min and NTS treatments were 117.34, 119.23 and 72.51 ng/ml, respectively. pH of longissimus dorsi muscle was higher in TS-L30 min than other treatments. TS-L30 min lambs had the highest shear force value, the lowest WHC and cooking loss. TS-L30 min treatment yielded the darkest meat immediately after cutting and 1 h later. Meat redness, yellowness and chroma values were similar in treatments. PMID:22197098

Neutrophil hypersegmentation in iron deficiency anaemia: a case-control study.  


Neutrophil hypersegmentation (NH) is an important haematological feature of cobalamin or folate deficiency. As iron deficiency and folate deficiency often occur in the same target groups it is important to establish whether iron deficiency alone is a cause of NH. We report a case-control study which addresses this issue. Two groups of hospital patients were studied. Group 1 comprised 50 patients with iron deficiency anaemia (IDA). Group II comprised 50 control age- and sex-matched patients who were haematologically normal without evidence of iron deficiency from the iron studies. Patients with other factors which could affect the degree of neutrophil segmentation (cobalamin/folate deficiency, renal failure, infection and drug exposures) were excluded from the study. A total of 10 000 neutrophils were examined, 100 from each patient. NH was defined as the presence of five or more five-lobed neutrophils per 100, or any neutrophils with six or more lobes. The results were as follows: IDA, mean neutrophil lobe count 3.36; number of patients with NH 31/50 (62%): controls, mean neutrophil lobe count 2.96, number of patients with NH 2/50 (4%). These differences were statistically significant. We conclude that NH is common in IDA. The mechanism whereby iron deficiency results in NH is not clear. PMID:10583250

Bone marrow culture in aplastic anemia.  

PubMed Central

Blood and bone marrow granulocyte colony forming units (CFUc) were assayed in 46 patients with aplastic anemia, and the serum was examined for its inhibitory action on normal CFUc growth. All patients showed a gross reduction in colonies and clusters in incidence and absolute number in the bone marrow and blood. Two proliferative abnormalities of CFUc in aplastic anaemia were identified: a significantly higher than normal cluster to colony ratio (P less than 0.05) and a higher than normal ratio of granulocytes to total aggregates in the bone marrow. Eleven out of 34 patients tested had serum inhibitory to normal CFUc. These patients were indistinguishable from the rest on haematological and CFUc culture characteristics, and no correlation between the results of CFUc assay and haematological severity was found. The results suggest that the CFUc is abnormal in aplastic anaemia, the reduction in pool size being related to a failure of self-renewal, but an immunological role in the pathogenesis of aplastic anaemia remains unproven. The close relationship of CFUc incidence to the percentage of granulocyte precursors in the marrow, together with the failure of the CFUc assay to predict clinical severity, limits the practical use of the assay to the confirmation of diagnosis in aplastic anaemia.

Protection against experimental visceral leishmaniasis by immunostimulation with herbal drugs derived from Withania somnifera and Asparagus racemosus.  


Visceral leishmaniasis (VL) is a vector-borne parasitic disease targeting tissue macrophages. It is among the most neglected infectious diseases. As available therapeutics for treatment of this disease have many side effects, there is a need for safer alternatives. One of the immunopathological consequences of active visceral leishmaniasis is suppression of protective T-helper (Th)-1 cells and induction of disease-promoting Th-2 cells, and thus the treatment of VL relies on immunomodulation. In the current study, herbal drugs derived as whole-plant extracts of Asparagus racemosus and Withania somnifera were used to treat Leishmania donovani-infected BALB/c mice. Keeping the scenario of immunosuppression during VL in mind, the potential of these drugs in the restoration of murine Th-1-type protective immune responses was evaluated. To investigate the propensity of these drugs to treat VL, liver parasite load, delayed-type hypersensitivity responses and parasite-specific immunoglobulin levels were studied. Various biochemical and haematological tests were also carried out. A positive-control group used the standard drug treatment of sodium stibogluconate. Treatment of infected mice with A. racemosus and W. somnifera in combination at the higher dose of 200 mg (kg body weight)(-1) not only resulted in a successful reduction in parasite load but also generated protective Th1-type immune responses with normalization of biochemical and haematological parameters, suggesting their potential as potent anti-leishmanial agents.

Hypolipidaemic effect of crude extract from Carpobrotus rossii (pigface) in healthy rats.  


Carpobrotus rossii (CR) was used by the Aboriginal population and early European settlers both as a food and therapeutic agent. Based on the presence of flavonoids in CR and results from our previous in vitro investigations, this study aimed to determine whether consumption of CR crude leaf extract: (a) affected lipoprotein profile, resting glucose, systolic blood pressure and vascular function, and (b) produced toxic effects (haematological measures, organ weight) in healthy rats. Male Hooded-Wistar rats (~230 g) were supplemented for 4 weeks with CR extract in their drinking water (35 mg/kg body weight daily). CR extract produced a significant decrease (18%, p=0.033) in atherogenic lipoproteins (but not high density lipoprotein). CR supplemented animals showed no signs of haematological toxicity and body and organ weight, daily fluid and food consumption and in vitro vascular responsiveness were similar for both groups. CR also increased (40%, p=0.049) the renal concentration of 3-hydroxy-3-methylglutaric acid (HMG), consistent with HMG-containing CR flavonoids being bioavailable, and therefore possessing the potential to interfere with cholesterol synthesis pathways. CR extract appears to be safe to ingest and may reduce cardiovascular risk. PMID:24480043

Raised levels of interleukin 6 in systemic lupus erythematosus correlate with anaemia  

PubMed Central

Objectives: Raised levels of the cytokines interleukin (IL) 6 and IL10 have been reported in patients with systemic lupus erythematosus (SLE). Objective: To determine if levels of IL6 and IL10 correlate with organ/system-specific disease activity in SLE, using the British Isles Lupus Assessment Group (BILAG) Disease Activity Index. Methods: Levels of IL6 and IL10 in serum samples from 171 patients with SLE and 50 normal controls were determined by enzyme linked immunosorbent assay (ELISA). Levels of cytokines in individual patients with SLE were compared with the presence or absence of active disease in eight organ/systems using the BILAG index. Results: Levels of IL6 were significantly higher (p = 0.005) in patients with active compared with inactive haematological disease, as scored by the BILAG index. Further analysis showed that this association was dependent on an inverse correlation (p = 0.002, r = –0.26) between IL6 levels and haemoglobin levels in patients with SLE. In contrast, IL10 levels did not correlate with individual organ/system disease activity. Conclusions: Raised levels of IL6 in SLE may influence the development of anaemia in this disease. These findings are in agreement with an increasing number of studies, which support physiological links between IL6 and anaemia. Importantly, with the exception of the haematological system, our studies do not provide evidence of any individual organ/system which would respond to therapeutic manipulation of either IL6 or IL10 levels.

The Longitudinal Assessment of Osteomyelitis Development by Molecular Imaging in a Rabbit Model  

PubMed Central

Introduction. Osteomyelitis is a severe orthopaedic complication which is difficult to diagnose and treat. Previous experimental studies mainly focussed on evaluating osteomyelitis in the presence of an implant or used a sclerosing agent to promote infection onset. In contrast, we focused on the longitudinal assessment of a nonimplant related osteomyelitis. Methods. An intramedullary tibial infection with S. aureus was established in NZW rabbits. Clinical and haematological infection status was evaluated weekly, combined with X-ray radiographs, biweekly injections of calcium binding fluorophores, and postmortem micro-CT. The development of the infection was assessed by micro-PET at consecutive time points using 18F-FDG as an infection tracer. Results. The intramedullary contamination of the rabbit tibia resulted in an osteomyelitis. Haematological parameters confirmed infection in mainly the first postoperative weeks (CRP at the first 5 postoperative weeks, leucocyte differentiation at the second and sixth postoperative weeks, and ESR on the second postoperative week only), while micro-PET was able to detect the infection from the first post-operative week onward until the end of the study. Conclusions. This study shows that osteomyelitis in the rabbit can be induced without use of an implant or sclerosing agent. The sequential follow-up indicates that the diagnostic value of each infection parameter is time point dependant. Furthermore, from all parameters used, the diagnostic value of??18F-FDG micro-PET is the most versatile to assess the presence of an orthopaedic infection in this model. PMID:25295260

Dose-dependent olanzapine-associated leukopenia: three case reports.  


Leukopenia and agranulocytosis are well reported and dangerous haematological side-effects associated with the use of typical and atypical antipsychotics. These potentially life-threatening phenomena have led to treatment discontinuation and the consequent reemergence of psychiatric symptoms. We report three cases of patients who developed leukopenia during olanzapine treatment. In each case, the leukopenia was dose-dependent. Reduction in the dose of olanzapine was followed by normalization of the white blood count which allowed continuation of the medication. These cases suggest the possibility that, in some patients, leukopenia or agranulocytosis during olanzapine treatment might be dose-related. Thus, olanzapine dose reduction may permit treatment continuation where this is clinically indicated. In our cases, haematological side-effects were satisfactorily controlled by dose reduction without allowing the reemergence of psychiatric symptoms. This clinical management may offer an alternative to treatment suspension. A careful monitoring of the white blood count is obviously recommended. Olanzapine may be considered a potential and safer treatment for a this specific group of patients. PMID:11236070

Effect of Euphorbia hirta plant leaf extract on immunostimulant response of Aeromonas hydrophila infected Cyprinus carpio  

PubMed Central

The main objective of the present study is to improve the immune power of Cyprinus carpio by using Euphorbia hirta plant leaf extract as immunostimulants. The haematological, immunological and enzymatic studies were conducted on the medicated fish infected with Aeromonas hydrophila pathogen. The results obtained from the haematological studies show that the RBC count, WBC count and haemoglobin content were increased in the infected fish at higher concentration of leaf extract. The feeds with leaf extract of Euphorbia hirta were able to stimulate the specific immune response by increasing the titre value of antibody. It was able to stimulate the antibody production only up to the 5th day, when fed with higher concentrations of (25 g and 50 g) plant leaf extract. The plant extract showed non-specific immune responses such as lysozyme activity, phagocytic ratio, NBT assay, etc. at higher concentration (50 g) and in the same concentration (50 g), the leaf extract of Euphorbia hirta significantly eliminated the pathogen in blood and kidney. It was observed that fish have survival percentage significantly at higher concentration (50 g) of Euphorbia hirta, when compared with the control. The obtained results are statistically significant at P < 0.05 and P < 0.01 levels. This research work suggests that the plant Euphorbia hirta has immunostimulant activity by stimulating both specific and non-specific immunity at higher concentrations.

A phase Ib trial of docetaxel, carboplatin and erlotinib in ovarian, fallopian tube and primary peritoneal cancers  

PubMed Central

The safety and maximum tolerated dose (MTD) of erlotinib with docetaxel/carboplatin were assessed in patients with ovarian cancer. Chemonaive patients received intravenous docetaxel (75?mg?m?2) and carboplatin (area under the curve 5) on day 1 of a 3-week cycle, and oral erlotinib at 50 (cohort 1), 100 (cohort 2a) or 75?mg?day?1 (cohort 2b) for up to six cycles. Dose-limiting toxicities were determined in cycle 1. Forty-five patients (median age 59 years) received treatment. Dose-limiting toxicities occurred in 1/5/5 patients (cohorts 1/2a/2b). The MTD of erlotinib in this regimen was determined to be 75?mg?day?1 (cohort 2b; the erlotinib dose was escalated to 100?mg?day?1 in 11 out of 19 patients from cycle 2 onwards). Neutropaenia was the predominant grade 3/4 haematological toxicity (85/100/95% respectively). Common non-haematological toxicities were diarrhoea, fatigue, nausea and rash. There were five complete and seven partial responses in 23 evaluable patients (52% response rate). Docetaxel/carboplatin had no measurable effect on erlotinib pharmacokinetics. In subsequent single-agent maintenance, erlotinib was given at 100–150?mg?day?1, with manageable toxicity, until tumour progression. Further investigation of erlotinib in epithelial ovarian carcinoma may be warranted, particularly as maintenance therapy. PMID:18506181

Lack of toxicity of a non-sporidesmin-producing strain of Pithomyces chartarum in cell culture and when dosed to lambs.  


In New Zealand the fungus Pithomyces charturum normally produces sporidesmin, a mycotoxin, which is responsible for the hepatogenous photosensitisation disease known as facial eczema. Cultures from an isolate of P. charturum, which does not produce sporidesmin, were examined by cell culture and by dosing to lambs to determine whether other toxic metabolites were produced. Acute and long term toxicity studies were conducted with the toxic response being assessed by weight changes, postmortem and histological examination of tissues, blood biochemistry and haematology tests. An extract from a sporidesmin-producing isolate was highly toxic in cell culture, while extracts of the nonsporidesmin-producing isolate did not cause a cytotoxic response to HEp 2 cells. After dosing with a sporidesmin-producing isolate, lambs developed liver lesions and clinical signs of facial eczema. Serum biochemistry changes occurred which were consistent with sporidesmin poisoning. Lambs dosed with the nonsporidesmin-producing isolate, at the rate of thirty times the number of spores of the sporidesmin-producing isolate, showed no observable toxic effects. All organs were of normal appearance, and histological examination of tissues, blood biochemistry and haematology results showed no abnormal changes. Similarly, long term dosing of extracts of the nonsporidesmin-producing isolate, at a rate equivalent to 100,000 spores/g of grass, produced no indication of a toxic response. It was concluded that the nonsporidesmin-producing isolate of P. churtarum contained no toxic metabolites in significant concentration. PMID:16031914

Preliminary observations on leukaemia specific agglutinins from seeds.  


Semipurified saline extracts of seeds from Crotolaria juncea, Cassia marginata, Ficus racemosa, Cicer arietinum (L-532), Gossipium indicum (G-27), Melia composita, Acacia lenticularis, Meletia ovalifolia, Acacia catechu and Peltophorum ferrenginium were tested for leukoagglutinating activity against whole leukocytes and mononuclear cells from patients with chronic myeloid leukaemia (34), acute myeloblastic leukaemia (5), acute lymphoblastic leukaemia (7), chronic lymphocytic leukaemia (3), various lymphoproliferative/haematologic disorders (54), and normal healthy subjects (50). In addition, bone marrow cells from three patients undergoing diagnostic bone marrow aspiration and activated lymphocytes from mixed lymphocyte cultures (MLC) were also tested. All the seed extracts agglutinated white blood cells from patients with different types of leukaemia. But none of them reacted with peripheral blood cells of normal individuals, patients with various lymphoproliferative/haematologic disorders or cells from MLC. Leukoagglutination of leukaemic cells with each of the seed extracts was inhibited by simple sugars. Only in one instance, cells from bone marrow of an individual who had undergone diagnostic bone marrow aspiration for a non-malignant condition were agglutinated. It is felt that purification of these seed extracts may yield leukaemia-specific lectins. PMID:2347609

Long-term follow-up and second malignancies in 487 patients with hairy cell leukaemia.  


A large, multicentre, retrospective survey of patients with hairy cell leukaemia (HCL) was conducted in France to determine the frequency of second malignancies and to analyse the long-term effects of the established purine nucleoside analogues (PNAs), cladribine and pentostatin. The survey retrospectively reviewed the medical history of patients and their immediate family, clinical and biological presentation at the time of HCL diagnosis, treatment choice, response to treatment, time to relapse and cause of death. Data were collected for 487 patients with HCL. Of the patients included in the survey, 18% (88/487) had a familial history of cancers, 8% (41/487) presented with malignancies before HCL diagnosis and 10% (48/487) developed second malignancies after HCL was diagnosed. An excess incidence of second malignancies was observed, with a standardized incidence ratio (SIR) of 1·86 (95% confidence interval (CI): 1·34-2·51), with no significant difference between PNAs. For second haematological malignancies alone, the SIR was markedly increased at 5·32 (95% CI: 2·90-8·92). This study highlights the high frequency of cancers in HCL patients and their family members. The frequency of second malignancies is notably increased, particularly for haematological malignancies. The respective role of pentostatin and cladribine in the development of second malignancies is debatable. PMID:24749839

Lenalidomide and dexamethasone for systemic AL amyloidosis following prior treatment with thalidomide or bortezomib regimens.  


The outcomes and responses to treatment remain poorly studied among patients with systemic AL amyloidosis who require further treatment following prior novel agent-based therapy. We report here treatment with lenalidomide-dexamethasone in 84 AL amyloidosis patients with relapsed/refractory clonal disease following prior treatment with thalidomide (76%) and/or bortezomib (68%). On an intention-to-treat (ITT) basis, the overall haematological response rate was 61%, including 20% complete responses. The median overall survival (OS) has not been reached; 2-year OS and progression-free survival (PFS) was 84% and 73%, respectively. Achieving a free light chain (FLC) response was an independent good prognostic factor for OS in multivariate analysis. There was no impact of prior thalidomide or bortezomib therapy on response rate, OS or PFS. 16% achieved an organ response at 6 months, with a marked improvement in organ responses in patients on long term therapy (median duration 11 months) and 55% achieving renal responses by 18 months. Lenalidomide/dexamethasone therapy achieves good haematological responses in patients with AL amyloidosis with relapsed/refractory clonal disease. The rate of renal responses among patients who received prolonged treatment was unexpectedly high, raising the possibility that immunomodulatory effects of lenalidomide therapy might enhance the otherwise slow natural regression of amyloid deposits.

Haematogram and serum iron status of malnourished Nigerian children.  


Haematological parameters, total serum iron, and total iron binding capacity (TIBC) concentrations were estimated in twenty protein energy malnourished (PEM) children, five kwashiorkor (K), five marasmus (M), five marasmic-kwashiorkor (M-K), and five undernourished (U) aged between one and five years on admission and after 18 days hospitalisation at Obafemi Awolowo University Teaching Hospital Complex. The Hospital diet for K and M-K consisted of 8% protein and 802 calories per litre while that for M and U consisted of 30% protein and 1350 calories per litre. After the period of 18 days of rehabilitation there was no significant (p > 0.05) difference (Student's t-test) in the weight for age. None of the haematological parameters was significantly different after rehabilitation for all the four types of PEM. Of the four types only Kwashiorkor with mean serum iron values of 15.6 +/- 1.51 micrograms/100 ml and 21.17 +/- 0.33 micrograms/100 ml on admission and after rehabilitation respectively was significantly (P < 0.05) different. More attention by the OAUTHC authorities needs to be paid to the management, feeding and diet given to these children so that there will be a greater and more rapid improvement in their rehabilitation.

Effective estimation of correct platelet counts in pseudothrombocytopenia using an alternative anticoagulant based on magnesium salt.  


Pseudothrombocytopenia remains a challenge in the haematological laboratory. The pre-analytical problem that platelets tend to easily aggregate in vitro, giving rise to lower platelet counts, has been known since ethylenediamine-tetra acetic acid EDTA and automated platelet counting procedures were introduced in the haematological laboratory. Different approaches to avoid the time and temperature dependent in vitro aggregation of platelets in the presence of EDTA were tested, but none of them proved optimal for routine purposes. Patients with unexpectedly low platelet counts or flagged for suspected aggregates, were selected and smears were examined for platelet aggregates. In these cases patients were asked to consent to the drawing of an additional sample of blood anti-coagulated with a magnesium additive. Magnesium was used in the beginning of the last century as anticoagulant for microscopic platelet counts. Using this approach, we documented 44 patients with pseudothrombocytopenia. In all cases, platelet counts were markedly higher in samples anti-coagulated with the magnesium containing anticoagulant when compared to EDTA-anticoagulated blood samples. We conclude that in patients with known or suspected pseudothrombocytopenia the magnesium-anticoagulant blood samples may be recommended for platelet counting. PMID:23808903

Biological, hormonal, and psychological parameters in professional soccer players throughout a competitive season.  


We examined changes in the haematological, metabolic, immunological, hormonal, and psychological fields using selected variables in 20 professional soccer players. over the course of a competitive season. The team performance was assessed by computing the winning percentage. A symptom checklist was used to assess the severity of upper respiratory tract infections. A high-intensity training programme induced a significant increase in cortisol and uric acid concentrations. Despite lower glutamine concentrations than the normal range throughout the study, infection occurred only in two of the soccer players. Moreover, the levels of immunological factors IgA, IgG, and IgM, and the haematological parameters were unaltered. Subsequent decreased performance coincided with changes in specific mood states of the team. Our results show some alterations on the metabolic, hormonal, and psychological variables over the five fields studied, suggesting that combined psychological and physiological changes during training are of primary interest to monitor the training stress in relation to performance in team sport.

Trends in the prevalence of invasive fungal infections from an analysis of annual records of autopsy cases of Toho University.  


Clinical diagnosis of invasive fungal infections (IFIs) is sometimes difficult, and obtaining an accurate assessment of trends concerning the prevalence of IFIs is a challenge. The aim of this study was to determine trends in the prevalence of IFIs from an autopsy survey. The retrospective review of autopsy records stored in Toho University was performed on all documented cases with fungal infection from 1955 to 2006. A total of 411 cases of IFIs were detected among 10 297 autopsies. The prevalence of candidiasis decreased from 3.6% (1981-93) to 2.0% (1994-2006), and that of aspergillosis increased throughout the 52-year period and reached 2.0% (1994-2006). The prevalence of IFIs in the patient group comprising haematological disorders was significantly higher (19.9%) than in other patient groups (2.9%), of which the odds ratio was 18.4 for mucormycosis and 10.0 for aspergillosis. The lung was the most common organ involved irrespective of major fungal species, and most cases with candidiasis showed multiple-organ infection. Results confirmed the increasing prevalence of aspergillosis and high risk of IFIs in the patient group with haematological disorders. IFIs were also detected in an immunocompromised state caused not only by primary disease but also by treatment with anti-tumour drugs and corticosteroids. PMID:22320199

Toxicity of cadmium and protective effect of bee honey, vitamins C and B complex.  


The present work aimed to study the toxic effect of cadmium (Cd) on rabbits' blood indices, as well as the therapeutic effect of the antioxidant agents, vitamins C and B complex and bee honey on Cd intoxicated rabbits. Cadmium chloride (CdCl2) was injected subcutaneously at a dose of 3 mg/kg of body weight. The results showed a significant increase in serum glucose, triglycerides, cholesterol, total protein, albumin, globulin, urea and creatinine, compared to the control group. In addition, CdCl2 intoxication increased the levels of uric acid, aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase and bilirubin. Concerning haematological parameters, the more obvious changes were an increase in mean corpuscular volume and a decrease in white blood cells count, platelets, lymphocytes, heamatocrit, haemoglobin and red blood cells count. Treatment of CdCl2-intoxicated animals with vitamins C and B complex and bee honey showed a decrease in the harmful effects of Cd by restoring haematological and biochemical changes. Bee honey treatment was the most effective in providing recoveries in the altered blood parameters. PMID:23111883

Reproductive activities of Heliotropium indicum isolate against Helopeltis theivora and toxicity evaluation in mice.  


A new compound E was isolated from the methanolic extract of the leaves of Heliotropium indicum by chromatographic fractionation. In the present study, the effect of the compound E on reproduction of Helopeltis theivora has been evaluated. The acute toxicity study (LD50) and sub-acute toxicity studies (haematological, biochemical and histopathological parameters) in albino Swiss mice were carried out to evaluate the safety aspect of the compound E. The compound showed significant inhibitory effect on the reproductive life of H. theivora. The oviposition period, fecundity and hatching percentage of H. theivora were found to be 15.67 days, 39.33 and 28.00% respectively after treatment with 2% compound E, whereas the control value were found to be 20.33 days, 77.67 and 77.33% respectively. The LD50 of the compound was found to be 780 mg kg(-1) in Swiss albino female mice. The compound did not show any toxicity in mice at sub-lethal dose treatment (78 mg kg(-1) b. wt., once daily) for 21 days as evident from
