There are about 4010 clinical studies being (or have been) conducted in Argentina. 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.
Controlled ovarian stimulation (COS) for FIV increases progesterone (P) and estradiol (E2) serum levels in supraphysiologic concentrations at the end of follicular phase. Elevated serum P levels leads to an accelerated endometrial maturation which interferes with the dialogue between embryo and endometrium. It has been reported that serum progesterone levels ≥ 1.5 ng/ml on the last day of COS are related to a significant decrease in the ongoing pregnancy rate following IVF cycles. Also, it has been reported a significant alteration in the endometrial gene expression profile related to P elevated levels. Glycodelin-A is an immunomodulatory glycoprotein synthesized by luteal-phase endometrial epithelium and its expression seems to be related to the action of P. Because glycodelin-A has immunosuppressive activity, it may facilitate the process of implantation and the maintenance of pregnancy. It is already know that ulipristal acetate (UPA) decrease serum P levels. The hypothesis of this study is that UPA is been able to modify P serum levels and glycodelin-A endometrial expression pattern on FSH/GnRH Antagonist cycles for FIV.
Acute respiratory infections are the leading cause of hospitalization in premature infants worldwide. Severity rates are particularly high in developing countries. Numerous viruses can cause severe disease, but the most frequent agent of hospitalization is respiratory syncytial virus (RSV). In a recent study in Argentina, 58% of RSV infected VLBW infants required hospitalization and 19% required mechanical ventilation. One every twenty infected infants died. Unlike industrialized nations, VLBW infants in developing countries often lack access to prophylaxis against RSV with a commercially available monoclonal antibody (palivizumab). No vaccine or preventive intervention is available against any respiratory virus for infants younger than 6 months of age in developing countries and the public sector of most middle-income countries. The protective role of breastfeeding against respiratory infections in developing countries is well established. But while similar beneficial effects have been described for premature infants, the dropout rate for breastfeeding in families exposed to the uncertainties and stress of the early months of life in the neonatal intensive care unit is very high. The World Health Organization recommends the use of Human Milk Donor Banks to feed infants that cannot be breastfed by their own mothers. These banks are established with the purpose of collecting, screening, processing (including pasteurizing), testing and distributing donated human milk. The potential benefit of donated milk against acute disease elicited by RSV is unknown. The investigators propose to study the role of supplemental donated human milk in the prevention of hospitalizations caused by RSV in non-breastfeeding premature infants. Since the investigators expect the benefits of breast milk to extend beyond protection against RSV, the effect of human milk against respiratory infections elicited by other viruses will also be evaluated.
This is a multi-national, multi-centre, placebo-controlled, double-blind, randomized, 4-arm parallel group trial, comparing three different dose levels (80 mg, 160 mg and 320 mg) of veltuzumab to placebo, administered weekly (days 1, 8, 15 and 22) by subcutaneous (sc) injection to subjects with moderate to severe rheumatoid arthritis (RA) (cumulative veltuzumab doses 320 mg, 640 mg, and 1280 mg, respectively). All subjects will be on continued stable co-medication with methotrexate (MTX).
Several environmental factors have contributed to the growing pandemic of obesity. It has been described that some characteristics of food and built environment have an influence on patterns of food consumption and physical activity of people in a certain place. We have designed a cross-sectional study to describe some aspects of the food environment (community and consumer) and the frequency, distribution and characteristics of the space available to perform physical activity in three neighborhoods of Buenos Aires city. Three neighborhoods of Buenos Aires (with representativity), from different socioeconomic strata, will be selected by convenience to conduct this study. The study will consist on three stages: first, the generation of the sampling frame of food stores, public and private spaces available for carrying out physical activity, and the development of a tool designed to evaluate the availability of healthy foods in supermarkets and grocery stores. Finally, a sample of those stores will be randomly selected for assessing the availability of selected foods. In Argentina, the knowledge of the food environment is limited. We believe that the information obtained in this study will contribute to a better understanding of the subject.
The purpose of this study is to determine the prevalence of patients with acute and chronic pain in the area of inpatient at the Hospital Italiano de Buenos Aires.
The purpose of this study is to assess the safety, efficacy, tolerability and pharmacokinetics of four doses of BMS-663068 with Raltegravir (RAL) + Tenofovir Disoproxil Fumarate (TDF). At least 1 dose of BMS-663068 can be identified which is safe, well tolerated, and efficacious when combined with RAL + TDF for treatment-experienced HIV-1 infected subjects.

MARCH is an international, multicentre trial planning to enroll 380 HIV-1 infected patients who are currently on 2N(t)RTI + PI/r regimen and virologically suppressed. Participants will be randomized (1:2:2) to one of three treatment groups: to continue their current treatment regimen, maraviroc dose at 150 mg twice daily with PI/r, or maraviroc at 300 mg twice daily with 2N(t)RTI. As the participants population have HIV RNA <200 copies/mL, the phenotypic assessment of tropism cannot be used to determine tropism, instead we will employ the genotypic assessment of tropism by sequencing the V3 loop of the HIV envelope. The main aim of this study is to investigate whether switching to maraviroc, in combination with either RTI or PI/r, is as good at keeping the HIV viral load undetectable as the combination of RTI with PI/r. The other aim is to see if switching to these combinations with maraviroc will improve some of the side effects that can be seen when people take combination therapy including RTI and PI/r. The study hypothesis is that in stable, virologically suppressed (plasma HIV-RNA <200 copies/mL) patients with no history of prior virological failure, a switch to either MVC dosed at 300mg twice daily (bid) combined with the same 2N(t)RTI backbone regimen or MVC dosed at 150mg twice daily (bid) with the current PI/r (or 300mg bid at the discretion of the investigator if the PI/r is fosamprenavir/r) provides similar (non-inferior) antiretroviral efficacy compared to continuation of the current 2N(t)RTI + PI/r regimen.
Objectives: The overall objective is to monitor efficacy of mebendazole (MBZ) against Soil-Transmitted Helminths (STH). The primary objective is: (1) to monitor the efficacy a single dose 500 mg of mebendazole (MBZ) against Soil-Transmitted Helminths (STH) infections by means of Faecal Egg Count Reduction (FECR) and Cure Rate (CR). The secondary objectives are: 1. to assess the occurrence of Necator americanus and Ancylostoma duodenal. 2. to assess the occurrence of β-tubulin mutations related to resistance before and after drug administration. 3. to evaluate the role of dogs and pigs as reservoir for zoonotic transmission.
The first aim of this trial is to assess the long-term prognostic value of Omega-3 index, which is a measure of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) relative to other fatty acids in the erythrocyte membrane, in an unselected, regional multicenter observational study of 982 chest pain patients admitted to the emergency unit, employing blood samples collected at admission. The second purpose of this study is to evaluate the prognostic utility of vitamin D in the same population. The third purpose of this study is to assess the incremental prognostic value of B-type natriuretic peptide (BNP) and high-sensitive C-reactive protein (hsCRP).
This study will assess the safety and efficacy of secukinumab when added to a background therapy in patients with active rheumatoid arthritis (RA) who are intolerant to or have had an inadequate response to anti-tumor necrosis factor (TNF)-α agents.
