Filter by:Rationale and Background: Since 2013, Butantan Institute has been performing passive pharmacovigilance activities related to its triavalent, fragmented and inactivated vaccine (IB TIV). Objetive: To conduct an active surveillance study focusing on the elderly and health care professionals as part of Butantan pharmacovigilance plan, while passive surveillance activities will continue. The pharmacovigilance plan, via active surveillance, is being implemented in response to WHO requirements for pre-qualification of IB TIV.
Insertion and maintenance of central venous catheter (CVC) lines are common hospital procedures in patients, including those being treated for cancer. CVCs allow clinicians an access point for infusion of fluids, blood sampling, and measurements, decreasing the need for repeated needle sticks to the patient. However, bloodstream infections associated with CVCs (CLABSIs) are a serious complication, leading to significantly longer hospital stays, morbidity, and mortality. Keeping catheter ports disinfected reduces the risk of bloodstream infection; however, consistent and adequate maintenance and disinfection of the line can be difficult. The purpose of this study is to demonstrate that passive disinfecting caps can provide a patient safety practice that is easy for clinicians to follow, as well as providing easily auditable compliance, which may lead to lower CLABSI rates. The compliance rate for needleless connector disinfection will be evaluated after implementation of the passive disinfecting cap, and compared to the pre-intervention rate. The CLABSI rates before and after cap implementation will also be compared.
Phase IV prospective study measuring the immunogenicity (neutralizing antibody titles against each HPV vaccine genotype) of the 9-valent vaccine against HPV (Gardasil9®Merck) in HIV-positive women aged 15-40 years with fully suppressed HIV viremia on combined antiretroviral therapy. After a first open phase evaluating tolerability of Gardasil9 (from June 2018 to December 2018), an amendment was introduced to randomize women between two different doses schedules: in the first schedule (ARM A), women will receive 2 doses at time 0 and 6 months and a third dose between 18-48 months if their antibody levels are insufficient; the second schedule (ARM B) will be 3 doses at 0, 2 and 6 months. Primary outcome is the non-inferiority of the rate of seroconversion against each HPV vaccine genotypes in women seronegative at baseline after either 2 or 3 doses of vaccination (month 7). Secondary outcomes are rate of seroconversion after 3 doses if they have received a third dose, completion of vaccine schedule, vaccine safety, antibody titles, and induction of cellular immunity against HPV contained in the vaccine, incidence of cervical HPV infection and incidence of abnormal cytology after vaccination. The safety of the vaccination (local or systemic reaction and impact on HIV viral control and immunodeficiency level) will be assessed. The cellular immune response will be assessed in a subgroup of patients.
Antibiotic resistance has emerged world wide and is of major concern. Multidrug resistant (MDR) bacteria is widely spread and is now a major factor in morbidity and mortality in health-care settings. Among MDRs, carbapenem resistant Enterobacteriaceae (CRE) are of special concern, receiving the highest classification of "urgent threat level" in the US President Report. Consistent mortality rates of 40-50% are observed among inpatients with infections caused by CRE in hospitals worldwide, related mainly to unavailable, delayed or ineffective antibiotic treatment options. The extremely high mortality rates of patients with CRE infections have driven efforts to prevent the acquisition and spread of these bacteria in hospitals. These include screening for carriage, contact isolation of carriers, cohorting, dedicated healthcare staff and other infection control measures. These strategies have been proven as effective but are cumbersome and expensive. In most locations these strategies failed to completely eradicate CRE endemicity. CRE decolonization (eradication of colonization) might offer a double benefit - reducing the risk for the individual carrier to develop an infection due to the resistant strain (by that, potentially lowering the mortality risk) and preventing the bacteria from spreading to other patients, exposing them to the same hazard. Fecal microbiota transplantation (FMT), in which fecal material enriched with commensal microorganisms is transferred from a healthy donor, have proven efficacy in the treatment of recurrent Clostridium difficile infection (CDI) in multiple trails. Major adverse events that has been reported so far are mostly related to the route of administration (aspiration during nasogastric tube administration/colonoscopy). Other adverse events include mostly GI related symptoms (diarrhea, nausea, belching) and are self limited and resolve in few hours. FMT seems to be safe and effective both in immunocompetent and immunocompromised patients. The high efficacy of FMT in the treatment of a multi-drug resistant pathogen such as Clostridium difficile, suggest that it might be an efficient tool for other MDR pathogens (e.g. CRE). This study aim to assess the effects of FMT on colonization and clinical infections with CRE. The potential of FMT to restore the gut microbiome and compete with residual resistant strains offer a novel way to fight the current MDR epidemic. FMT will be applied in a randomized open label fashion to CRE carriers in a single center in Israel and will be given by capsules for 2 consecutive days followed by rectal sampling at predefined timepoint in the following 6 months.
It is widely known that vitamin D has an important role in calcium metabolism and bone mineralization. Its deficiency is related to rickets and osteomalacia in children and adults respectively. Vitamin D had a role in innate and acquired immunity. It increases innate defense and modulates lymphocytes activation, leading to a change toward a T2 helper response ). The role of vitamin D deficiency on the risk of bacterial infection among patients in intensive care units has been reported. An observational studies in children reported an association between low 25-OH vitamin D level and infectious viral diseases . The deranged metabolism of vitamin D in liver cirrhosis was first reported in the late '70s and was attributed mainly to impaired 25(OH)-vitamin D hydroxylation of the precursor vitamin D caused by impaired liver function. Low level of vitamin D was found independently to be associated with increased risk of bacterial infections in patients with liver cirrhosis. The observed relationship between the lack of vitamin D and the increase risk of mortality in cirrhotic patients could be attributed to bacterial infections. Thus, the association of low vitamin D levels with liver insufficiency and infections supports the use of vitamin D as a prognostic marker in the population of cirrhosis. Studies on the role of vitamin D as a risk factor for infections in patients with liver cirrhosis are not well studied in our locality(Upper Egypt).
This study determines the effectiveness of oral nystatin as prophylaxis in order to prevent systemic fungal infection in very low birth weight preterm neonates. 47 participants received oral nystatin and 48 participants received sterile water as part of oral hygiene.
The purpose of this study is to assess the duration of the viral shedding in hematology and oncology patients after a respiratory tract viral infection. This duration has not been much studied in that population whereas it is probably longer than that in immunocompetent patients. Thereby it may be a source of transmission amongst these immunocompromised patients.
Open-label, multicentre, prospective cohort, observational clinical trial with a retrospective control group to evaluate the effectiveness and safety of CERAMENTTM| G or V used for filling of bone defects in the tibia and / or femur shaft and/or acetabulum in patients scheduled for two-stage hip or knee prosthesis re-implantation for PJI or aseptic loosening. The results will be compared to a cohort of patients, which have been treated before the introduction of CERAMENTTM|G or V for the same indication. Due to the observational character of the study, there will be no patient randomization and the clinicians in the study will remain entirely free to decide on the treatment of the patients according to established clinical practice. Only patients for whom therapeutic strategy for the use of the product for filling bone defects is already planned according to local clinical practice, at the time of informed consent form signature, will be enrolled in this study. Thus, the decision for the choice of the surgical treatment, will not be influenced by the inclusion of the patient in this study.
, the study aimed at assessing the frequency of rising procalcitonin associated with infectious complications in immunosuppressed LDLTRx.
Background: One of the main causes of respiratory infections in children and adults is RSV. This stands for respiratory syncytial virus. Healthy adults usually get a cold when they get an infection with RSV. They generally recover without any problems. But some infections can be life-threatening. Researchers want to study RSV infection in a safe, controlled setting in healthy adults to help develop new treatments. Objective: To test the safety of a high dose of RSV A2 by spraying the virus into the nose, and studying how the body responds. Eligibility: Healthy adults ages 18-50 Design: Participants will be screened during 2 screening visits with: - Medical interview - Physical exam - Blood and nasal samples - Chest X-ray (chest radiograph) - Participants will have a heart test. Sticky patches on the body will detect heart electrical activity. - Pulmonary function test (PFT). They will blow into a machine to measure airflow. - Urine tests for pregnancy or drug use. Participants will be admitted to the hospital before they get RSV A2. Participants will get a single dose of RSV A2 as two sprays, one into each nostril. Participants will stay in the hospital under isolation for as long as it takes the body to clear RSV A2 from nasal fluids. This can take as long as 14 days or more. Participants cannot take any cold medicine to try to feel better. Every day, participants will: - Answer questions about their symptoms - Have nasal washes and/or nasal swabs collected - Have a physical exam Participants will have blood drawn most days. After discharge, participants will keep a health diary. Participants will have 2 follow-up visits at 1 month and 2 months after receiving the RSV A2 dose. A history and physical examination, a blood draw, and nasal wash and swab will be performed.
