Risk of bias and confounding of observational studies of Zika virus infection: A scoping review of research protocols.

IntroductionGiven the severity and impact of the current Zika virus (ZIKV) outbreak in the Americas, numerous countries have rushed to develop research studies to assess ZIKV and its potential health consequences. In an effort to ensure that studies are comprehensive, both internally and externally valid, and with reliable results, the World Health Organization, the Pan American Health Organization, Institut Pasteur, the networks of Fiocruz, the Consortia for the Standardization of Influenza Seroepidemiology (CONSISE) and the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC) have generated six standardized clinical and epidemiological research protocols and questionnaires to address key public health questions on ZIKV.MethodsWe conducted a systematic search of ongoing study protocols related to ZIKV research. We analyzed the content of protocols of 32 cohort studies and 13 case control studies for systematic bias that could produce erroneous results. Additionally we aimed to characterize the risks of bias and confounding in observational studies related to ZIKV and to propose ways to minimize them, including the use of six newly standardized research protocols.ResultsObservational studies of ZIKV face an array of challenges, including measurement of exposure and outcomes (microcephaly and Guillain-Barré Syndrome). Potential confounders need to be measured where known and controlled for in the analysis. Selection bias due to non-random selection is a significant issue, particularly in the case-control design, and losses to follow-up is equally important for the cohort design.ConclusionObservational research seeking to answer key questions on the ZIKV should consider these restrictions and take precautions to minimize bias in an effort to provide reliable and valid results. Utilization of the standardized research protocols developed by the WHO, PAHO, Institut Pasteur, and CONSISE will harmonize the key methodological aspects of each study design to minimize bias at different stages of the study. Biases need to be considered by researchers implementing the standardized protocols as well as by users of observational epidemiological studies of ZIKV.

20.130 ISARIC – enhancing the clinical research response to epidemics

Purpose: The International Severe Acute Respiratory and emerging Infection Consortium (ISARIC) is a network of networks that was established in 2011 by investigators from around the world to ensure a rapid research response to outbreaks of pandemic potential. By bringing together multidisciplinary research groups in more than 110 countries across different resource settings, ISARIC has supported research responses to Ebola in West Africa, MERS-CoV in the Middle East and elsewhere, and more recently, the Zika outbreak in Latin America and the Caribbean.

Feasibility of a randomized controlled trial to assess treatment of Middle East Respiratory Syndrome Coronavirus (MERS-CoV) infection in Saudi Arabia: a survey of physicians.

BackgroundThe Middle East Respiratory Syndrome coronavirus (MERS-CoV) is an emerging respiratory pathogen with a high mortality rate and no specific treatments available to date. The purpose of this study was to determine the feasibility of conducting a randomized controlled trial (RCT) of convalescent plasma therapy for MERS-CoV-infected patients by using MERS-CoV-specific convalescent plasma obtained from previously recovered patients.MethodsA survey was adapted from validated questionnaire originally aimed to measure network capacities and capabilities within the International Severe Acute Respiratory and emerging Infection Consortium (ISARIC). The questionnaire was modified for this study to include 26 items that were divided into three main domains of interest: (1) the ability to care for critically ill MERS-CoV patients; (2) laboratory capacity to diagnose MERS-CoV and blood bank ability to prepare convalescent plasma; and (3), research capacity to conduct randomized controlled trials. The questionnaire was emailed to physicians.ResultsOf 582 physicians who were invited to the survey, 327 responded (56.2 %). The professional focus of the majority of respondents was critical care (106/249 (43 %)), pediatrics (59/249, (24 %)) or internal medicine (52/249 (21 %)) but none was blood banking. Nearly all respondents (251/263 (95 %)) reported to have access to ICU facilities within their institutions. Most respondents (219/270 (81 %)) reported that intensivists were the most physician group responsible for treatment decisions about critically ill SARI patients. While 125/165 respondents (76 %) reported that they conduct research in ICUs, and 80/161 (49.7 %) had been involved in the conduct of RCTs, including using a placebo comparison (60/161 (37 %)), only 49/226 (21 %) of respondents regularly participated in research networks.ConclusionsOur survey indicated that in the Kingdom of Saudi Arabia (KSA), ICUs are the most likely clinical locations for conducting a clinical trial of convalescent plasma therapy for MERS-CoV, and that most ICUs have experience with such research designs.Electronic supplementary materialThe online version of this article (doi:10.1186/s12871-016-0198-x) contains supplementary material, which is available to authorized users.

Middle East Respiratory Syndrome Coronavirus (MERS-CoV): a perpetual challenge.

Ann Saudi Med 2013 September-October www.annsaudimed.net 427 The emergence of a novel human coronavirus recently renamed the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) from the Arabian Peninsula has created global alarm because it is the causative agent of a severe and frequently fatal acute respiratory illness (SARI) resembling the illness caused by severe acute respiratory syndrome (SARS) coronavirus (SARS-CoV).1-4 The case fatality rate (CFR) in patients infected with MERS-CoV is high—estimated at 43% in 147 patients reported so far by World Health Organization (WHO).3 This rate is higher than that of SARS—estimated at 15%, and is strongly ageand sex-dependent.4 Although the source of virus in patients with sporadic infection remains unknown, it appears likely to be some species of animal.4,5 Clear evidence of limited human-to-human transmission of MERS-CoV has now been documented in several case clusters, including particularly family members and patients in health care facilities,6-8 but all such clusters have, at least thus far, been limited in extent. However, a real concern persists that the virus will adapt to interhuman transmission and switch from an aborted epidemic to a pandemic similar to the SARS-CoV epidemic in 2003–2004. MERS-CoV is transmitted through droplets and contact. In the case of invasive respiratory procedures, MERS-CoV is transmitted through airborne route.2 Early diagnosis and strict implementation of the core components for infection prevention and control programs are crucial for preventing epidemic amplification.2 In the absence of an effective vaccine and a specific antiviral treatment, there is an urgent need to rapidly identify potential therapeutics.
