Active clinical trials for "Communicable Diseases"

A new strain of coronavirus that caused severe respiratory disease in infected individuals was initially identified in China's Wuhan City in December 2019. Severe acute respiratory distress syndrome coronavirus-2 (SARS-CoV-2), which was responsible for the corona virus infectious disease-2019 (COVID-19).The World Health Organization declared that COVID-19 was a Public Health Emergency of International Concern on January 30,2020. The impact of COVID-19 in liver recipients remains largely unknown but accumulating experience is going on. Liver transplant recipients should have been classified as a risk group and should have received regular surveillance for COVID-19 throughout the pandemic. Some reports suggest decreasing immunosuppression for infected recipients, if no recent rejection episodes. Paradoxically, others suggest that a reactive immune response might be the cause for severe tissue damage, and that immunosuppression might be protective from the postulated cytokine storm. Some studies stated that the LT patients who are permanently on immunosuppressants could be particularly susceptible to SARS-CoV-2, and their prognosis could be worse in comparison to the normal population. They recommended that LT recipients should be closely monitored for SARS-CoV-2. The LT society of India (LTSI) highlighted the potential of LT recipients as asymptomatic carriers and source of viral spread, and that SARS-CoV-2 can be transmitted to LT recipients. There are insufficient data on the relationship between immunosuppressive therapy and COVID-19 in LT recipients during this pandemic. However, the Beijing working party for liver transplantation suggested that LT recipients who were infected with SARS-CoV-2 should be treated with steroids for a short period to reduce the severity of pneumonia. They also suggested that immunosuppressive therapies should be continued for both patients with mild COVID-19 and those who were not infected by the virus, and calcineurin inhibitor treatment dosage should be reduced in moderate to severe cases. Neutralizing antibodies (NAbs) play an important role in virus clearance and have been considered as a key immune product for protection or treatment against viral diseases. Virus-specific NAbs, induced through either infection or vaccination, have the ability to block viral infection. SARS-CoV -2 specific NAbs reached their peak in patients from day 10-15 after the onset of the disease and remained stable thereafter in the patients. Antibodies targeting on different domains of S protein, including S1, RBD, and S2, may all contribute to the neutralization. Al-Rajhi Liver Center is the only liver transplantation center in Upper Egypt that performed only 51 living donor liver transplantation (LDLT) cases since 2014, but it was used as isolation Hospital for COVID-19 cases from March to July, 2020. Communication with liver transplant cases during that period was via Telemedicine. Resuming usual Hospital activity as Tertiary Liver Center occurred in 15 August 2020. Similarly, other Hospitals in Egypt were designated as COVID-19 isolation Hospitals.

To investigate the influence of antibiotics on the incidence of biliary tract infections after PTCD for malignant obstructive jaundice.

The AGMT_COVID-19 Registry is designed as multicenter observational cohort of patients, that are tested positive for SARS-CoV-2. Data will be collected from all sites in Austria willing to participate. Due to the non-interventional nature of the AGMT_COVID-19 registry, only routine data, which has already been recorded in the patient's medical chart, is transferred to the eCRF.

this prospective study we will examine the prevalence of fungal infection in patients undergoing oral cavity surgery without treatment with antifungal drug

PHENOTYPE is an investigator-led, observational cohort study which aims to explore the long-term outcomes of patients with COVID-19 infection and to identify potential risk factors and biomarkers that can prognosticate disease severity and trajectory.

7. Objectives To apply e-health methods to perform active monitoring and assess determinants of incident Infection of COVID-19 in a hospital population. 8. Study design Prospective, Single-centre, observational clinical study. 9. Disease or disorder under study Healthy people in risk of COVID-19 infection. 10. Main variable. Symptoms related to infection caused by SARS-Cov2. 11. Study population and total number of patients Men and women in general god health status aged between 18 and 80 years that currently are employees of Hospital de La Princesa . 12. Duration of treatment Each subject will be monitored, since its recruitment, for a period of 12 weeks. 13. Timetable and expected date of completion The overall duration of the study is estimated at about 6 months, from patient recruitment to the last data recorded by last subject. The aim is to carry out this study from March 2020 onwards.

There are lack of endoscopic criteria for diagnosing Helicobacter pylori (H. pylori) infection by conventional white light imaging (WLI). Linked color imaging (LCI) is a newly developed endoscopy technique, which can diagnose mucosal lesions and H. pylori infection by enhancing color contrast of the mucosa. The aim of the study is to investigate the ability of LCI for diagnosing H. pylori infection compared with WLI.

Understanding the emergence of linezolid-resistance in Staphylococci has been allowed in the past years through the discovery of the clonal dissemination of a chromosomal cassette carrying a modified crf gene. New mutations have even been described. Though, clinical evidences are still lacking, especially concerning the factors associated to this emergence. It could seriously become quite problematic to eliminate one of the last therapeutic weapon at our disposal for the treatment of severe or complicated infections caused by resistant strains of Staphylococci and Enterococci. We aim to describe the mechanisms that permitted to this resistance to become clinically significant, concerning meticillin-resistant Staphyloccocus epidermidis strains causing blood stream infections in ICU patients, and show the clinical risk factors associated with it through a case-control study on patients hospitalized in two ICUs of our hospital between 2011 and 2016.

Lung transplantation (LTx) , DNA-based testing. Performance of DNA-based testing of bacterial and fungal pathogens in comparison to standard testing. Experimental intervention: DNA-based testing of BAL fluid.

The investigators hypothesis: Presence of anti-GGT (antibody against GGT) indicates H. pylori infection.
