Rapid antigen tests for dengue virus serotypes and Zika virus in patient serum

 

Authors: Bosch I, de Puig H, Hiley M, et al.

Abstract: The recent Zika virus (ZIKV) outbreak demonstrates that cost-effective clinical diagnostics are urgently needed to detect and distinguish viral infections to improve patient care. Unlike dengue virus (DENV), ZIKV infections during pregnancy correlate with severe birth defects, including microcephaly and neurological disorders. Because ZIKV and DENV are related flaviviruses, their homologous proteins and nucleic acids can cause cross-reactions and false-positive results in molecular, antigenic, and serologic diagnostics. We report the characterization of monoclonal antibody pairs that have been translated into rapid immunochromatography tests to specifically detect the viral nonstructural 1 (NS1) protein antigen and distinguish the four DENV serotypes (DENV1–4) and ZIKV without cross-reaction. To complement visual test analysis and remove user subjectivity in reading test results, we used image processing and data analysis for data capture and test result quantification. Using a 30-μl serum sample, the sensitivity and specificity values of the DENV1–4 tests and the pan-DENV test, which detects all four dengue serotypes, ranged from 0.76 to 1.00. Sensitivity/specificity for the ZIKV rapid test was 0.81/0.86, respectively, using a 150-μl serum input. Serum ZIKV NS1 protein concentrations were about 10-fold lower than corresponding DENV NS1 concentrations in infected patients; moreover, ZIKV NS1 protein was not detected in polymerase chain reaction–positive patient urine samples. Our rapid immunochromatography approach and reagents have immediate application in differential clinical diagnosis of acute ZIKV and DENV cases, and the platform can be applied toward developing rapid antigen diagnostics for emerging viruses.

“Not Taking it Will Just be Like a Sin”: Young People Living with HIV and the Stigmatization of Less-Than-Perfect Adherence to Antiretroviral Therapy.

 

Authors: Bernays S, Paparini S, Seeley J, Rhodes T.

Published inMed Anthropol. 2017;36(5):485-499.

Abstract: Global health priorities are being set to address questions on adherence to HIV antiretroviral therapy in adolescence. Few studies have explored young people’s perspectives on the complex host of social and relational challenges they face in dealing with their treatment in secret and their condition in silence. In redressing this, we present findings from a longitudinal qualitative study with young people living with HIV in the UK, Ireland, US, and Uganda, embedded within the BREATHER international clinical trial. Drawing from Goffman’s notion of stigma, we analyze relational dynamics in HIV clinics, as rare spaces where HIV is “known,” and how young people’s relationships may be threatened by non-adherence to treatment. Young people’s reflections on and strategies for maintaining their reputation as patients raise questions about particular forms of medicalization of HIV and the moralization of treatment adherence that affect them, and how these may restrict opportunities for care across the epidemic.

The Challenge of Treating Children with Hepatitis C Virus Infection

 

Authors: Indolfi G, Thorne C, El-Sayed MH, Giaquinto C, Gonzalez-Peralta RP.

Published in: J Pediatr Gastroenterol Nutr. 2017.

Abstract: The development of oral hepatitis C virus (HCV) direct-acting antivirals (DAAs) has revolutionized the therapeutic field. Nowadays, multiple safe and highly effective antiviral regimens are commercially available to treat adults with hepatitis C infection. These new regimens for the first time genuinely raise the prospects of eradicating HCV. Many challenges, however, remain from identifying infected individuals to optimizing treatment and ensuring global access to antiviral therapy to all population groups, including children.

Qualitative study of the BREATHER trial (Short Cycle antiretroviral therapy): is it acceptable to young people living with HIV?

 

Authors: Bernays S, Paparini S, Seeley J, Namukwaya Kihika S, Gibb D, Rhodes T.

Published inBMJ Open. 2017;7(2):e012934

Abstract: A qualitative study of the BREATHER (PENTA 16) randomised clinical trial, which compared virological control of Short Cycle Therapy (SCT) (5 days on: 2 days off ) with continuous efavirenz (EFV)-based antiretroviral therapy (CT) in children and young people (aged 8–24) living with HIV with viral load <50 c/mL to examine adaptation, acceptability and experience of SCT to inform intervention development
