Filter by:BACKGROUND: One couple out of 6 consults for infertility during their sexual life. In 60% of cases a male factor is associated or is the main infertility factor. Inflammatory Syndrome (IS), characterized by the presence of a leukocytospermia is found in 12% of the cases. Leukocyte degranulation causes oxidative stress (OS) through the formation of free radicals attacking the sperm cell functions. HYPOTHESIS: To establish the responsibility of the IS, and OS, in chronicle inflammatory male infertility, the investigators hypothesize that its treatment (as well as its possible cause) must restore or improve the fertilizing capacity of patients sperm. METHODS: This prospective randomized study will test the response to the treatment. The investigators shall measure cellular degradation products due to the OS, thereby certifying that it does have a deleterious effect on sperm cell. Seminal biochemistry will also assess the impact of the syndrome on the genital tract glands and follow its evolution. The patients will be included in the study as soon as the leukocytospermia will be > 0,5*106/ml or as soon as the elastase will be > 500 ng/mL. The examinations will be performed using flow cytometry, CASA (Computer Assisted Semen Analysis). The analysis of sperm morphology will be centralized. Primary endpoint will be a reduction in the percentage of 8OH-dG below 35 %. We anticipate that it should arrive to 20 % of the patients included in the arm treatment by corticosteroid therapy. All in all will thus be needed 50 patients in the group placebo and 50 in the group treated. Secondary endpoint the improvement of the spermatic parameters and the reduction of the fragmentation of the DNA of sperm cells to the treated subjects. All these biological markers will be evaluated 6 month after the treatment: - Fragmentation of the spermatic DNA below 37 % during the follow-up in 6 months - Leukocytospermia and elastase - Seminal biochemistry - Other markers of the inflammatory syndrome and oxidative stress (protein carbonyl, 8OHd-Guanosine) - Possibly the radiological examinations (Ultrasound and MRI of the genital tract) In addition it would allow us to propose a policy of prevention towards acquired post-infectious male infertility.
This is a two-year double blind, placebo-controlled, and randomized clinical trial, which is aimed to evaluate the effects of Chinese medical treatment on leucopenia after chemotherapy in breast cancer patients.
The purpose of this study is to study the efficacy of Traditional Chinese Medicine (TCM) on anaemic and cytopenic haematological disorders including myelodysplastic syndrome (MDS), aplastic anaemia (AA), myelofibrosis (MF) and thalassemia intermedia who do not have or did not respond to available treatment options.
Many breast cancer patients will taking Chinese herbal medicine during receiving radiotherapy. The investigators conducted the pilot study showing Compound Herbal Formula (TPE-1) have the effect of improving the fatigue and leukopenia during radiotherapy. So the investigators designed this double blind and controlled trial to evaluate whether TPE-1 have the effects for leukopenia and cancer-related fatigue in breast cancer patients with radiotherapy. From our initial observation for 2 years, TPE-1 is safety. The study is also designed to evaluate the safety when patients taking this formula.
Background: - WHIMS (Warts, Hypogammaglobulinemia, Infections, and Myelokathexis Syndrome) is caused by various genetic changes that increase the activity of the chemokine receptor, CXCR4. Excessive function of this receptor causes mature neutrophils (part of the white blood cells) to be retained within the bone marrow rather than being released to the blood and is one of the causes of severe inherited neutropenia (low white blood counts). In neutropenia, the body is less able to fight off infection. Patients with WHIMS usually are at risk for skin, soft tissue, sinus, and lung infections, which can result in loss of hearing, teeth, and lung function. - Current treatment for WHIMS consists of regular injections of a white blood cell growth stimulating medication called granulocyte colony stimulating factor (G-CSF), and supplemental immunoglobulin (antibody). These therapies are expensive, nonspecific, have significant side effects and toxicities, and do not fully correct all problems, especially warts and cancers related to human papillomavirus (HPV). - A drug called Mozobil has been approved for use in combination with G-CSF to increase the number of stem cells that can be collected prior to bone marrow transplantation. Mozobil may offer a specific and well-tolerated new treatment for WHIMS and other syndromes characterized by neutropenia. Objectives: - To evaluate whether Mozobil is safe and effective to treat neutropenia (low white blood cell count) in patients with WHIMS. - To determine an appropriate treatment dose of Mozobil, within currently approved dosage levels. Eligibility: - Individuals between 18 and 75 years of age who have been diagnosed with WHIMS and have a history of severe infections. Design: - Potential participants will undergo a screening with a medical history, physical examination, questionnaire, heart and lung function scans, and blood and urine samples. Tests will also be done for hepatitis B and C virus, and human immunodeficiency virus (HIV) that causes acquired immunodeficiency syndrome (AIDS), as well as to check neutrophil function. - Patients who are being treated with G-CSF will stop injections for 2 days before being admitted to the National Institutes of Health (NIH) Clinical Center. - Patients may participate in a Dose Escalation study and receive increasing doses of Mozobil over 5 days of treatment until their white blood cell count improves sufficiently or the maximum approved dose is reached. Blood samples will be taken regularly throughout the treatment process. Patients will then receive an additional dose of Mozobil at the maximum approved dose or the dose sufficient to cause improvement, before restarting the G-CSF injections. - Patients may also participate in a long-term Chronic Dosing study and receive Mozobil once or twice a day for up to a maximum of 60 months.
A randomized, open label parallel controlled, multicenter study to evaluate safety and efficacy of Posaconazole oral suspension vs Fluconazole (capsule) in high-risk leukopenic patients for prevention of invasive fungal infection
This phase I trial studies the side effects and best dose of iodine I 131monoclonal antibody BC8 when given together with fludarabine phosphate, cyclophosphamide, total-body irradiation, and donor bone marrow transplant, and to see how well they work in treating patients with acute myeloid leukemia or acute lymphoblastic leukemia that has spread to nearby or other places in the body (advanced), or high-risk myelodysplastic syndrome. Giving chemotherapy drugs, such as fludarabine phosphate and cyclophosphamide, and total-body irradiation before a donor bone marrow transplant helps stop the growth of cancer or abnormal cells and helps stop the patient's immune system from rejecting the donor's stem cells. Also, radiolabeled monoclonal antibodies, such as iodine I 131 monoclonal antibody BC8, can find cancer cells and carry cancer-killing substances to them without harming normal cells. When the healthy stem cells from a donor are infused into the patient they may help the patient's bone marrow make stem cells, red blood cells, white blood cells, and platelets. Sometimes the transplanted cells from a donor can make an immune response against the body's normal cells. Giving cyclophosphamide together with mycophenolate mofetil and tacrolimus after the transplant may stop this from happening. Giving a radiolabeled monoclonal antibody together with donor stem cell transplant, fludarabine phosphate, cyclophosphamide, mycophenolate mofetil, and tacrolimus may be an effective treatment for advanced acute myeloid leukemia, acute lymphoblastic leukemia, or myelodysplastic syndromes.
The purpose of this prospective, randomized study was to determine the efficacy of low bacterial diet, in comparison to normal hospital diet, with gut colonization by aerobic Gram negative rods and yeasts as primary endpoint. In addition, the occurrence of infections and the total costs of hospital care were documented, in order to identify potential cost savings by the use of either diet.
This study will include 60 patients with early breast cancer referred to receive adjuvant chemotherapy with AC ( adriamycin- cyclophosphamide) or CAF ( adriamycin- cyclophosphamide- 5- fluorouracil ) combinations. These patients will receive every day one spoon of Lifemel honey or regular honey ( double blind)- during the adjuvant chemotherapy .Every week a WBC count will be performed in order to record the influence of Lifemel on myelotoxicity.
In recent decades, hematologists have noticed that persons of African descent sometimes have lower white blood cell counts of a certain type, called granulocytes. These cells help to fight infections. The lower number of granulocytes in this situation does not appear to lead to more infections, and these individuals do not have any symptoms. This condition is called benign ethnic neutropenia (BEN), and is observed in a small percentage of individuals of African descent. This study will investigate the condition by studying people with and without BEN. The goals of this study are to: 1. identify individuals of African descent with BEN. 2. determine the effects of two drugs, G-CSF and dexamethasone, on granulocyte production and movement. 3. determine whether there are differences in those with and without BEN in the way genes are stimulated after the administration of G-CSF and dexamethasone. Study participants will be asked to interview with the research team, undergo physical exams, donate a blood sample, and receive G-CSF by injection, followed by dexamethasone (orally) about three weeks later. They also will be required to undergo apheresis three times, a procedure in which blood is drawn from a donor and separated into its components. Some components are retained for research analyses, such as granulocytes, and small amount of blood; the remainder is returned by transfusion to the donor. This procedure will be required of participants before they receive G-CSF, the day after they receive G-CSF, and the day after they receive dexamethasone. Gene messages (mRNA will be isolated from granulocytes, and analyzed to better understand granulocyte growth and movement.
