Is global elimination of HCV realistic?

2017

The elimination of hepatitis C virus (HCV) has been made possible through the availability of new antiviral drugs which may now be administered to all patients with HCV infection, even those with decompensated cirrhosis. The goal of the World Health Organization (WHO) is to reduce the incidence of chronic hepatitis infection from the current 6-10 million to 0.9 million cases of chronic infections by 2030, and annual deaths from 1.4 million to fewer than 0.5 million. Achieving these targets will require full implementation of epidemiological knowledge of HCV infection, screening and testing practices and strategies to link HCV patients to care. This review will focus on the current state of …

CD4saurus Rex & HIVelociraptor vs. development of clinically useful immunological markers: a Jurassic tale of frozen evolution.

2011

Abstract One of the most neglected areas of everyday clinical practice for HIV physicians is unexpectedly represented by CD4 T cell counts when used as an aid to clinical decisions. All who care for HIV patients believe that CD4+ T cell counts are a reliable method to evaluate a patient immune status. There is however a fatalistic acceptance that besides its general usefulness, CD4+ T cell counts have relevant clincal and immunological limits. Shortcomings of CD4 counts appear in certain clinical scenarios including identification of immunological nonresponders, subsequent development of cancer on antiretroviral teatment, failure on tretment simplification. Historical and recently described…

Telemedicine during Covid-19 pandemic: Advantage or critical issue?

2020

Telemedicine offers a support to traditional medicine, delivering clinical services when distance is a critical factor. Although this tool does not replace a medical examination, during Covid-19 pandemic, it reduces the spread of infection and avoids the need for a patient’s visit. It is useful in the management of chronic disorders or for patients undergoing palliative treatment. The University Hospital of Palermo has applied this in cases of chronic illness caring for patients who cannot stop their treatment, such as Department of Onco-Haematology, Internal Medicine, Dermatology, etc. The Department of Legal Medicine of Palermo, in particular, is also using telemedicine to manage medico-…

Telemedicine Online Visits in Urology During the COVID-19 Pandemic-Potential, Risk Factors, and Patients' Perspective.

2020

The current coronavirus disease 2019 (COVID-19) pandemic has placed considerable strain on hospital resources. We explored whether telemedicine (defined as a videoconference) might help. We undertook prospective structured phone interviews of urological patients (n = 399). We evaluated their suitability for telemedicine (judged by a panel of four physicians) and their risks from COVID-19 (10 factors for a poor outcome), and collected willingness for telemedicine and demographic data. Risk factors for an adverse outcome from COVID-19 infection were common (94.5% had one or more) and most patients (63.2%) were judged suitable for telemedicine. When asked, 84.7% of patients wished for a teleme…

No Evidence for Classic Thrombotic Microangiopathy in COVID-19

2021

Background: Coronavirus disease-2019 (COVID-19) triggers systemic infection with involvement of the respiratory tract. There are some patients developing haemostatic abnormalities during their infection with a considerably increased risk of death. Materials and Methods: Patients (n = 85) with SARS-CoV-2 infection attending the University Medical Center, Mainz, from 3 March to 15 May 2020 were retrospectively included in this study. Data regarding demography, clinical features, treatment and laboratory parameters were analyzed. Twenty patients were excluded for assessment of disseminated intravascular coagulation (DIC) and thrombotic microangiopathy (TMA) due to lack of laboratory data. Resu…

The effect of Dextransulfate 500 on the pathogenesis of herpes simplex virus infections in weanling mice

1978

Intraperitoneal (i.p.) injection of Dextran Sulfate (D.S.) 500 during a limited period of time influences the course of herpes simplex-virus-infections. D.S.500 was found to reduce the resistance of mice for some herpes simplex-virus strains (Len, L3-2s, Haase) if given between 16 hours before and 2 hours after i.p. infection. The decrease of resistance could be correlated with an increase of the virus content of liver, spleen, brain and spinal cord. Injection of herpes simplex-virus-specific immune serum counteracted the effect of D.S.500 on the course of infections. Conversely, D.S.500 increased the resistance of mice to another group of herpes simplex-viruses (strains D-316, Thea, DD), i…

Processing Sperm Samples in HIV-Positive Patients

2013

Human immunodeficiency virus is an important public health problem; about 40 million people around the world are actually infected with HIV type 1 virus. Furthermore, prolonged survival of patients under highly active antiretroviral therapy has given rise to a new demand from SDC couples who wish to have children. HIV serodiscordant couples with the male infected wish to make use of assisted reproduction techniques in combination with semen washing in order to decrease the risk of transmission to the partner or to the newborn. Thus it is essential to test the effectiveness of techniques aimed at reducing HIV and HCV loads in infected semen using molecular biology tests. Nevertheless, its ef…

Reliability of wastewater analysis for monitoring COVID-19 incidence revealed by a long-term follow-up study

2021

Background Wastewater-based epidemiology has been used for monitoring human activities and waterborne pathogens. Although wastewaters can also be used for tracking SARS-CoV-2 at the population level, the reliability of this approach remains to be established, especially for early warning of outbreaks. Methods We collected 377 samples from different treatment plants processing wastewaters of >1 million inhabitants in Valencia, Spain, between April 2020 and March 2021. Samples were cleaned, concentrated, and subjected to RT-qPCR to determine SARS-CoV-2 concentrations. These data were compared with cumulative disease notification rates over 7 and 14 day periods. Results We amplified SARS-CoV-2…
