Background: Infectious complications in febrile neutropenic patients are still major causes of morbidity and mortality despite significant advances in diagnostic techniques and antimicrobial therapy. In this study, we describe the characteristics of patients with hematological malignancies who were evaluated for suspected infection. This study was also conducted to assess the isolation rate of bacterial and fungal causative agents in febrile neutropenic attacks.Method: The study was conducted at Pamukkale University Hospital, Turkey. In order to identify the characteristics of patients with hematological malignancies in the presence/suspicion of any accompanying infectious disease, patients' charts with hematological malignancies were reviewed for signs/symptoms of any infection between October 1, 2001, and May 31, 2005, retrospectively.Results: Overall, 90 infectious episodes occurred in 59 patients. The most common underlying diseases were acute myelogenous leukemia (61.0%) and acute lymphocytic leukemia (15.3%). The absolute neutrophil count was lower than 100/mm(3) in 33 (36.7%) episodes. Microbiologically and clinically documented infections and fever of unknown origin were observed in 35.6%, 28.9%, and 35.6% of the participants, respectively. Bloodstream infections and pneumonia were detected in 21.1% and 18.9% of episodes, respectively. Gram negative organisms were most common (58.4%), followed by gram positive cocci. A combination of third generation cephalosporin and an aminoglycoside were used in 44.4% of episodes initially. Fever resolved in 24.4% of episodes using the initial therapy. The mortality rate was 15.6%.Conclusion: These results showed that infections with gram-negative bacteria continue to predominate in febrile neutopenic episodes in our center

(Oral) Ankaferd Blood Stopper in a Patient with Glanzmann Thrombasthenia

Background: Glanzmann Thrombasthenia (GT) is a genetic platelet dysfunction and a life threatening disease. Ankaferd Blood Stopper (ABS) is a topical hemostatic agent of herbal origin which has been recently made available for clinical use. Its hemostatic effect is independent from blood clotting factors and occurs as a result of the aggregation of focal red blood cells by an encapsulated protein web.Case Report: In this paper, a patient with GT is presented in whom 3 months of gastrointestinal bleeding refractory to all medical therapies was controlled within a short time of using oral ABS.Conclusion: The difference between this patient and other cases presented in the medical literature is the oral use of ABS. Thus, this patient may contribute to the medical community in showing the safety and efficacy of systemic (oral) ABS in patients with disorders of coagulation. However, there is a need for more patient experiences

in the rat liver

Background/aims: The tolerance of the liver is considerably low when an effective radiation (RTx) dose needs to be delivered in patients in whom either their liver or whole body area has to be irradiated. The aim of this study was to evaluate the possible protective effect of grape seed extract on liver toxicity induced by RTx in the rat liver. Methods: We used four groups, each consisting of 12 healthy male Wistar rats. RTx-grape seed extract group: rats were given grape seed extract (100 mg/kg) orally for seven days, following 8 Gy whole body irradiation, and grape seed extract was maintained for four days. RTx group: the same protocol was applied in this group; however, they received distilled water instead of grape seed extract. Grape seed extract group: only grape seed extract solution was administered for 11 consecutive days in the same fashion. Control group: only distilled water (orally) was administered in a similar manner. The level of malondialdehyde, an end product of lipid peroxidation, and the activities of superoxide dismutase and catalase, two important endogenous antioxidants, were evaluated in tissue homogenates. Results: Grape seed extract was seen to protect the cellular membrane from oxidative damage and consequently from protein and lipid oxidation. In the RTx group, malondialdehyde levels were extremely higher than those of the grape seed extract-RTx group (p0.05). Conclusions: The levels of antioxidant parameters on RTx-induced liver toxicity were restored to control values with grape seed extract therapy. Grape seed extract may be promising as a therapeutic option in RTx-induced oxidative stress in the rat liver

Rat Liver

The efficacy of methotrexate (MTX), a widely used cytotoxic chemotherapeutic the mechanisms of these adverse agent, is often limited by its severe hepatotoxicity. Regarding effects. several hypotheses have been put forward, among which oxidative stress is noticeable. The present study was undertaken to determine whether grape seed extract (GSE), a new natural free radical scavenger, Could ameliorate the MTX-induced oxidative injury in the rat liver. The animals were divided into 3 groups. Each group consisted of 12 animals. MTX-GSE group: rats were given GSE (100mg/kg body weight) orally for 15 days, and a single dose of MTX (20mg/kg, intraperitoneally) was added on the 10th day. MTX group: these received placebo distilled water (orally) instead of GSE for 15 days and the same MTX protocol applied to this group on the 10th day. Control group: rats were given distilled water (orally) through 15 days and physiological saline (intraperitoneally) instead of MTX was administered on the 10th day in a similar manner. On the 16th day, liver tissue samples were obtained under deep anaesthesia. The level of malondialdehyde (MDA), an end product of lipid peroxidation, and the activities of superoxide dismutase (SOD) and catalase (CAT), two important endogenous antioxidants, were evaluated in the tissue homogenates. MTX administration increased the MDA level and decreased the SOD and CAT activities in the liver homogenates (p < 0.001), while these alterations were significantly reversed by GSE treatment (p < 0.001). MTX led to significantly reduced whole blood count parameters (p < 0.05). When GSE was supplemented, no significant changes in blood Count parameters were noted. It appears that GSE protects the rat liver and inhibits methotrexate-induced oxidative stress. These data indicate that GSE may be of therapeutic benefit when used with MTX

Disturbance of pro-oxidative/antioxidative balance in allogeneic peripheral blood stem cell transplantation.

High dose chemotherapy causes increased free radical formation and depletion of tissue antioxidants. Whether allogeneic hematopoietic stem cell transplantation (HSCT) has an effect on oxidative stress is uncertain. The aims of the study were to determine the effect of allogeneic HSCT on plasma concentrations of antioxidants and oxidative stress biomarkers, and to investigate their relationships with graft-versus-host disease (GVHD), conditioning regimens, and transplant-related mortality (TRM) in patients with hematological malignancies. Patients (n=25) undergoing allogeneic HSCT from HLA-matched sibling donors were enrolled in the study. Plasma oxidant and antioxidant status were measured at day -1 before transplantation and 30 days after HSCT. In both myeloablative (n=14) and non-myeloablative (n=11) transplant groups, the mean levels of plasma malondialdehyde (MDA) and nitric oxide (NO) increased after allogeneic HSCT (p <0.01), whereas superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and catalase (CAT) activities decreased compared with baseline values (p <0.01). No significant relationships were found between either the pretransplant or post-transplant mean levels of the oxidative stress parameters and the existence of graft-versus-host disease (GVHD), the type of conditioning regimen, or transplant related mortality (TRM). This study documents a significant disturbance of pro-oxidative/antioxidative balance in the plasma of patients undergoing allogeneic HSCT regardless of the intensity of the conditioning regimen
