Filter by:Globally, about 248 million people are chronic HBV surface antigen carriers, and about 5% of them also had hepatitis delta virus (HDV) infection as well. The prevalence of HBsAg in Egypt is intermediate (2-7%) . Hepatitis D virus (HDV) is an incomplete RNA virus that needs hepatitis B surface antigen (HBsAg) to help its replication. HDV is considered a subviral particle because it depends on HBV for its propagation. Combined HDV- HBV infection produces more severe liver affection than HBV alone. HDV infection leads to both of acute and chronic liver illnesses. Acute HDV infection can occur at the same time with acute HBV infection (coinfection) or can be superimposed on the top of chronic HBV infection. About 20% to 30% of coinfections of HDV and HBV in humans develop fatal fulminant hepatitis versus 2% of patients with acute hepatitis B mono-infection. Worldwide, Hepatitis D virus (HDV) infection present in more than 15 million people and it is endemic in the Middle East . In Upper Egypt, data about the prevalence, clinical, laboratory and virological characters of Hepatitis D virus-infected patients is rare. This study aims were: 1. To estimate the prevalence of hepatitis D virus infection among HBsAg positive individuals. 2. To determine the clinical, laboratory and virological characters of HDV infected patients.
Sexually transmitted infections (STI) are important causes of reproductive health morbidity and mortality, and have long been implicated as major co-factors in the sexual transmission of HIV. Both ulcerative and non-ulcerative STI have been found to be strongly associated with HIV in cross-sectional and prospective studies and hence STI prevention and care are important aspects of HIV prevention. Periodic Presumptive Treatment of STIS (PPT) where risk populations are presumptively treated with a single dose of Azithromycin+Cefixime in regular intervals of 3 months has been shown to be effective in reducing STI prevalence at population level and has recently been integrated into the National STI guidelines of Tanzania. The USAID funded Sauti program will be one of the first to implement these new guidelines and roll out PPT in high risk populations in selected regions in Tanzania. This study will evaluate the impact of PPT as delivered by the Sauti program on prevalence of STIs in men who have sex with men and female sex workers in Dar es Salaam and Shinyanga respectively.
This single site study is a randomized, controlled, partially-blinded design enrolling a minimum of 516 healthy volunteers, where each subject will receive two of the planned study products on the product application sites of the abdomen and/or groin.
This study seeks to demonstrate the effectiveness and safety of the Non-valved Conduit for CE marking on the basis of infection. The rationale for infection resistance with the conduit is that BioIntegral Surgical No-React® treated products have a well-documented history of infection resistance in hybrid vascular settings.
The primary objective of this study is to evaluate invasive fungal infections (IFI) according to clinicians' opinion vs the opinion of an independent board of experts. The primary output of this study is the evaluation of inter-raters agreement. Secondary objectives are: evaluation of IFI incidence; description of clinical and laboratory features; frequencies of different antifungal treatments; description of outcome; impact on the treatment of underlying hematological malignancy. This is a multicenter, non-interventional observational, prospective study. The duration of the study will be 18 months. The study will recruit all consecutive eligible patients in each participating center, during a period of 6 months until at least 600 patients with acute myeloid leukemia are registered, that represented the highest risk category. Other disease types that fulfill the eligibility criteria in the participating centers during the same period will also be recruited in the study. The clinical, microbiological, diagnostic and therapeutic procedures operated on these patients will be collected. An eCRF will be compiled for all patients: T0: at the start of antifungal treatment, information will be collected regarding hematological malignancy, status of the disease at onset of infection and phase of treatment, last chemotherapy regimen, comorbidities and risk factors; previous IFI, neutropenia, antifungal and antibiotic prophylaxis and the kind of IFI clinicians retain the patient suffer (possible/probable/proven) and the kind of antifungal treatment started (empiric/pre-emptive/target); diagnostic work-up done, positive microbiology and biomarkers, positive radiological findings; antifungal treatment. T1: at 30-40 days (or before if the patient unfortunately died) a second form must be completed with information regarding any changes in/additional diagnostic work-up done, positive microbiology and biomarkers, positive radiological findings; any changes in antifungal treatment; outcome. At that time, the local physician must state any revision of his diagnostic classification between the moment in which antifungal treatment was started and the moment of evaluation of the outcome in order to estimate the differences regarding the level of evidence of diagnosis and treatment of IFI during time. Each case will be examined blinded by 2 different experts, who will review all records based on the existing guidelines, their own experience and the information that was known at the two time points, which may confirm or not the decision of local physician. The sample size will be driven by the AML patients (approximately 60-70% of the patients). Sample will be described in its clinical and demographic features via descriptive statistics. Quantitative variables will be summarized with the following measures: minimum, maximum, range, mean and standard deviation. Qualitative variables will be represented by frequencies tables.
A total of 50 patients with metastatic colorectal cancer will be enrolled in the study. The patients were randomly divided into the WLS-intervention group and the control group. The two groups of patients were given the most appropriate medication according to the specific conditions of the disease. Patients in the intervention group received additional oral administration of Weileshu, a probiotics product (Tongchuang Biotechnology).
The study will be conducted to evaluate the therapeutic response (combined per participant microbiological and clinical response) of oral gepotidacin compared to oral nitrofurantoin for treatment of uncomplicated UTI (acute cystitis) in adolescent and adult female participants.
The study will assess the safety and efficacy of AT-527 in combination with daclatasvir after 8 or 12 weeks of treatment.
Marrow transplanted immunocompromised patients with cytomegalovirus (CMV) viral infection will be treated with CMV activated T-Lymphocytes. T-Lymphocytes will be obtained through an apheresis from a compatible donor. Safety and immunoreconstitution parameters in blood samples will be assessed up to +60 days after the treatment.
Background: Clostridioides (formerly Clostridium) difficile Infection (CDI) is a persistent healthcare issue. In the US, CDI is the most common infectious cause of hospital-onset (HO) diarrhea. Objective: Assess the impact of admission testing for toxigenic C. difficile colonization on the incidence of clinical disease. Design: Pragmatic stepped-wedge Infection Control initiative. Setting: NorthShore University HealthSystem (NorthShore) is a four-hospital system near Chicago, Illinois. Patients: All patients admitted to the four hospitals during the initiative. Interventions: From September 2017 through August 2018 the investigators conducted a quality improvement program where admitted patients had a peri-rectal swab tested for toxigenic C. difficile. All colonized patients were placed in contact precautions. Measurements: The investigators tested admissions who: i) had been hospitalized within two months, ii) had a past C. difficile positive test, and/or iii) were in a long-term care facility within six months. The investigators measured compliance with all other measures to reduce the incidence of HO-CDI. Limitations: This was not a randomized controlled trial, and multiple prevention interventions were in place at the time of the admission surveillance initiative.
