There are about 10004 clinical studies being (or have been) conducted in Brazil. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
Diabetic nephropathy (DN) is a chronic diabetic complication and affects up to 40% of patients. The first line treatment for DN is angiotensin blockers drugs that are used to reduce the protein concentration in urine.Previous data showed that this protein, namely albuminuria, could also be reduced in a short term-period by the replacement of red meat in the diet with chicken. The aim of this study is to compare the effects of this chicken diet with enalapril on albuminuria in a long-term period( 12 months)in type 2 diabetic patients.
A new immunosuppressive drug, based on the inhibition of an important enzyme in the immune system called JAK3, is being developed by Pfizer to prevent transplant rejection. In this research study, a JAK3 inhibitor or cyclosporine will be given to new kidney transplant patients for 12 months. Patients will be assigned to one of three treatment groups after receiving a kidney transplant. Two of the treatment groups will receive 2 different dosing regimens of the JAK3 inhibitor that will be taken by mouth. The third treatment group will be a standard-of-care control arm. Patients will continue to take the assigned study medication for 12 months as well as other standard transplant medications such as prednisone.
To evaluate the safety and tolerability of multiple IV doses of the MEDIMUNNE antibody in adult patients with SLE.
The hemodynamic parameters of 31 pregnant women with rheumatic valve disease, undergoing restorative dentistry under local anesthesia with 2% solution of lidocaine, divided in two groups, with (Group LE) and without 1:100,000 epinephrine solution (Group LNE), were studied by 24-hour ambulatory electrocardiographic monitoring, intermittent blood pressure monitoring and continuous cardiotocography, during three standard time periods. A significant decrease in the values of maternal heart rate was seen during the procedure, in comparison with the other two time periods in the two groups, as well as, the occurrence of cardiac arrhythmia in 9 (29.1%) patients, being 7 (41.8%) of them in the group receiving epinephrine anesthesia. We conclude the use of 2% lidocaine in association with epinephrine proved safe during dental procedure in pregnant women with rheumatic valve disease.
Prolactin is suggested to influence insulin resistance, but scarce data is available on the metabolic profile of patients with prolactinoma. The purpose of the protocol was to evaluate cardiovascular disease risk factors in women with prolactinoma treated with dopamine agonists and to study the influence of disease control and anthropometry on their metabolic profile.
The purpose of this clinical research study is to compare the rate of confirmed complete cytogenetic response (cCCyR) of dasatinib to imatinib therapy within 12 months after randomization in newly diagnosed chronic phase Philadelphia positive chronic myeloid leukemia (Ph+ CML) patients. The safety of this treatment will also be studied.
The purpose of this study is to determine the effects of the anticholinesterase drug donepezil on sleep in Alzheimer disease patients. Sleep structure and respiratory parameters will be analyzed by polysomnography.
The purpose of this clinical trial is to demonstrate the benefit of the immunotherapeutic product GSK1572932A when given to patients with Non-Small Cell Lung Cancer, after removal of their tumor. A course of 13 injections will be administered over 27 months. The Protocol Posting has been updated in order to comply with the FDA Amendment Act, Sep 2007.
Hypovolaemia and tissue hypoperfusion can pass undetected during and after major surgery. The resulting systemic inflammatory response and organ dysfunction, often not clinically apparent for several days, may lead to increased morbidity and mortality and prolonged hospital stay. In this regard, intraoperative optimization of circulatory status by volume loading has been shown to improve the outcome of patients undergoing high-risk surgery. Indeed, several reports (1-7) have shown that monitoring and maximizing stroke volume by volume loading (until stroke volume reaches a plateau, actually the plateau of the Frank-Starling curve) during high-risk surgery decreases the incidence of post-operative complications and the length of hospital stay. Unfortunately, this strategy has required so far the measurement of stroke volume by a cardiac output monitor, as well as a specific training period for the operators (8), and hence is not applicable in many institutions as well as in many countries. The arterial pulse pressure variation (∆PP) induced by mechanical ventilation is known to be a very accurate predictor of fluid responsiveness, i.e. of the position on the preload/stroke volume relationship (Frank-Starling curve) (9). By increasing cardiac preload, volume loading induces a rightward shift on the preload/stroke volume relationship and hence a decrease in ∆PP. Patients who have reached the plateau of the Frank-Starling relationship can be identified as patients in whom ∆PP is low (9). Therefore, the clinical and intraoperative goal of “maximizing stroke volume by volume loading” can be achieved simply by minimizing ∆PP. We designed the present study to investigate whether monitoring and minimizing ∆PP by volume loading during high-risk surgery may improve post-operative outcome and decrease the duration of post-operative hospital stay.
To collect safety and tolerability data in a more diverse patient population of patients with HIV/Aids, who have limited therapeutic options.
