Invasive fungal disease (IFD) is a major infectious complication in patients with Hematological malignancies.In this study,we examined 4889 courses of chemotherapy in patients with Hematological diseases to establish a training dataset (n=3500) by simple random sampling to develop a weighted risk score for proven or probable IFD through multivariate regression,which included the following variables: male patients,induction chemotherapy for newly diagnosed or relapsed disease,neutropenia,neutropenia longer than 10 days,hypoalbuminemia,central-venous catheter,and history of IFD.The patients were classified into three groups,which had low (0-10,~1.2%),intermediate (11-15,6.4%),and high risk (> 15,17.5%) of IFD.In the validation set (n=1389),the IFD incidences of the groups were ~1.4%,5.0%,and 21.4%.In addition,we demonstrated that antifungal prophylaxis offered no benefits in low-risk patients,whereas benefits were documented in intermediate (2.1% vs.6.6%,P=0.007) and high-risk patients (8.4% vs.23.3%,P=0.007).To make the risk score applicable for clinical settings,a pre-chemo risk score that deleted all unpredictable factors before chemotherapy was established,and it confirmed that anti-fungal prophylaxis was beneficial in patients with intermediate and high risk of IFD.In conclusion,an objective,weighted risk score for IFD was developed,and it may be useful in guiding antifungal prophylaxis.

Background:Animal models are widely used in scientific research in order to obtain information from a whole organism under a specific set of experimental conditions.Various lineages of mice have been used to investigate diseases and new therapeutic strategies,and,consequently,Hematological and biochemical tests in these laboratory animals are essential to validate scientific studies.Our study seeks to establish reference values for Hematological and biochemical parameters of four lineages of mice.Methods:We evaluated the Hematological and biochemical profiles of 20 males and 20 females from the lineages Swiss(heterogeneous),BALB/c and C57BL/6(isogenic),and B6D2F1(hybrid),totaling 160 mice.Analysis were standardized using the systems pocH-100iV Diff™for 19 Hematological parameters and VITROS®350 for 12 biochemical parameters.Results:Results are shown as means and standard deviation,grouped by lineage and genre.Comparing the values obtained in this study with the values from previous studies,some variations were detected,which could be explained by differences in methodologies or individual variability.Conclusion:Thus our study shows that knowledge and disclosure of the values of physiological parameters of laboratory animals is necessary,and emphasises the importance of considering variations influenced by gender,lineage and genotype in the choice of the best experimental model.

Moderation of Hematological and plasma biochemical indices of subchronic salt-loaded rats,by an aqueous extract of the leaves of Acalypha wilkesiana 'Godseffiana' Muell Arg(Euphorbiaceae)

引用

Asian Pacific Journal of Tropical Medicine 2013年第1期6卷 37-42页

作者： Ikewuchi Jude C Department of Biochemistry Faculty of ScienceUniversity of Port HarcourtP.M.B.5323.Port HarcourtNigeria

Objective:To investigate the effects of an aqueous leaf extract of Acalypha wilkesiana (A.wilkesiana) on plasma chemistry and Hematological indices of sub-chronic salt-loaded rate. Method:The control group received a diet consisting 100%of the commercial feed,while the four test groups were received a diet consisting 8%salt and 92%commercial feed all through, except for the reference treatment group that had its salt-loading discontinued after six weeks. The extract was orally administered daily at 200 and 250 mg/kg body weight;while the test control,reference and control groups received appropriate volumes of water by the same route. Results:The extract had no negative effects on markers of liver and kidney functions,produced hemoconcentration,significantly higher(P<0.05) plasma calcium and potassium levels,and significantly lower(P<0.05) plasma sodium and chloride levels in the test animals compared to test control.Conclusions:This result supports the traditional use of A.wilkesiana in the management of hypertension and suggesls that the extract may be a potassium sparing diuretic whose mechanism of antihypertensive action may be via alteration of plasma sodium and potassium balances or calcium mediated alteration in vascular muscle tone.

Objective:To evaluate the effect of short term artemether administration on some blood parameters in adult male Wistar rats.Methods:Sixty five albino rats with body weight of 190-220 g were used for the four-phased study. The animals were randomly divided into five groups. The first-four groups of 15 rats were further divided into 3 subgroups of 5 rats. The drug was administered orally at sub-optimal, therapeutic, and high doses of 25, 50 and 75 mg/kg bw,respectively to the rats for 1 day, 2 days and 3 days. Blood samples were collected by cardio-puncture from the rats for hematology at the end of each phase. The last group served as control,and they were given waterad libitum.Results:Artemether caused significant reduction(PHematological profile of the animals in a dose dependent manner. Discontinuation of the drug use however showed gradual recovery of the depressed indices of the blood parameters.Conclusions:The results suggest that artemether can induce reversible changes in Hematological profiles of rats by extension man. This can probably aggravate anemia when artemether is administered to malaria patients. Hence, the study supports the use of the drug with cautione specially in patients prone to anemic tendencies.

Hepatitis due to hepatitis B virus(HBV) reactivation can be severe and potentially fatal, but is preventable. HBV reactivation is most commonly reported in patients receiving cancer chemotherapy, especially rituximabcontaining therapy for Hematological malignancies and those receiving stem cell transplantation. All patients with Hematological malignancies receiving anticancer therapy should be screened for active or resolved HBV infection by blood tests for hepatitis B surface antigen(HBs Ag) and antibody to hepatitis B core antigen(antiHBc). Patients found to be positive for HBs Ag should be given prophylactic antiviral therapy to prevent HBV reactivation. For patients with resolved HBV infection, no standard strategy has yet been established to prevent HBV reactivation. There are usually two options. One is pre-emptive therapy guided by serial HBV DNA monitoring, whereby antiviral therapy is given as soon as HBV DNA becomes detectable. However, there is little evidence regarding the optimal interval and period of monitoring. An alternative approach is prophylactic antiviral therapy, especially for patients receiving highrisk therapy such as rituximab, newer generation of anti-CD20 monoclonal antibody, obinutuzumab or hematopoietic stem cell transplantation. This strategy may effectively prevent HBV reactivation and avoid the inconvenience of repeated HBV DNA monitoring. Entecavir or tenofovir are preferred over lamivudine as prophylactic therapy. Although there is no well-defined guideline on the optimal duration of prophylactic therapy, there is growing evidence to recommend continuing prophylactic antiviral therapy for at least 12 mo after cessation of chemotherapy, and even longer for those who receive rituximab or who had high serum HBV DNA levels before the start of immunosuppressive therapy. Many novel agents have recently become available for the treatment of Hematological malignancies, and these agents may be associated with HBV reactivation. Although there is currently limited evidence to guide the opt

Objective: To investigated the Hematological, antioxidant and protective performance of Usnea longissima (U. longissima) on CCl4 induced hepatotoxicity in experimental animals. Methods: Hepatotoxicity was induced by CCl4 (1 mL/kg body weigt 1:1 CCl4 i.p.), ethanolic U. longissima extracts at a doses (200 and 400 mg/kg body weigt) were administered to and compared with Silymarin (25 mg/kg body weigt) and Hematological, antioxidant and enzymatic, non-enzymatic parameters were assessed through the liver functions test. All the observation was also supplemented with histopathological examination of liver sections. Results: Phytochemical investigation showed that ethanolic extract contains poly phenolic compounds tannins, flavonoids, alkaloids and saponins and acute toxicity study shows that ethanolic extract was safe up to 2000 mg/kg body weight. The toxicant induced a rise in the plasma enzyme levels of ALT, AST, ALP and total bilirubin level. This increased level was significantly decreased by the extract at 400 mg/kg body weight than 200 mg/kg body weight. The animals were prevented (partly or fully) which was showed in the histopathological changes using ethonolic U. longissima extract. Conclusions: The outcome of this study reveals that, there is a powerful antioxidant and hepatoprotective activity of U. longissima. It is believed that the present constituents are responsible for courting the hepatic disease and alternative components have the power to act as free radical scavenging properties.

Hepatitis B virus (HBV) infection affects a large part of the world population. Within the different virological HBV categories that have been identified, patients with occult HBV infection represent a peculiar group. These individuals harbor a replication competent virus, inhibited in its replicative function. Accordingly, cases of reactivations have been observed in immunosuppressed individuals who lose immunological control over the infection. Patients with Hematological malignancies (HM) are treated with intense myeloand immunosuppres-sive chemotherapy regimens which favor HBV reactivation. This event can have severe consequences, such as hepatitis flare, hepatic failure and even death. In addition, it can lead to delays or interruptions of curative treatments, resulting in a decreased disease free and overall survival. In this review, we will examine the event of HBV reactivation in patients with signs of resolved HBV infection undergoing treatment for HM and propose possible management strategies.
