We studied the role of viruses and atypical bacteria in children hospitalized with exacerbated asthma by a prospective study of children with acute asthma admitted to the Department of Pediatrics in Lille, and to 15 hospitals in the Nord-Pas de Calais region, from October 1, 1998-June 30, 1999. We included children aged 2-16 years with active asthma, defined as three or more recurrent episodes of reversible wheezing. The severity of asthma and of asthmatic exacerbations was recorded. Immunofluorescence assays (IFA) on nasopharyngeal secretions (NPS), serological tests, or both, were used for detection of influenza virus, respiratory syncytial virus (RSV), adenovirus, parainfluenza virus, and coronavirus. Polymerase chain reaction (PCR) assays on NPS were used for rhinovirus and enterovirus. Serological tests for Chlamydia pneumoniae and Mycoplasma pneumoniae were performed. A control group of asymptomatic asthmatic outpatients was examined for respiratory viruses (using IFA and PCR). Eighty-two symptomatic children (mean age, 7.9 years) were examined. Viruses were detected in 38% (enterovirus, 15.8%; rhinovirus, 12%; RSV, 7.3%). Serological tests for atypical bacteria were positive in 10% of patients (C. pneumoniae, 5%; M. pneumoniae, 5%). Among the 27 control subjects (mean age, 7.9 years), one PCR was positive for enterovirus. There was no correlation between severity of chronic asthma or asthmatic exacerbations and the diagnosis of infection. Atypical bacterial pathogen infections were linked with prolonged asthmatic symptoms. In conclusion, we confirmed the high incidence of viral infection in acute exacerbations of asthma, especially enteroviruses or rhinoviruses. Persistent clinical features were more frequently associated with atypical bacterial infections, suggesting that these infections should be investigated and treated in cases of persistent asthmatic symptoms.
IntroductionMeaningful patient engagement (PE) can enhance medicines’ development. However, the current PE landscape is fragmentary and lacking comprehensive guidance.MethodsWe systematically searched for PE initiatives (SYNaPsE database/publications). Multistakeholder groups integrated these with their own PE expertise to co-create draft PE Quality Guidance which was evaluated by public consultation. Projects exemplifying good PE practice were identified and assessed against PE Quality Criteria to create a Book of Good Practices (BOGP).ResultsSeventy-six participants from 51 organisations participated in nine multistakeholder meetings (2016–2018). A shortlist of 20relevant PE initiatives (from 170 screened) were identified. The co-created INVOLVE guidelines provided the main framework for PE Quality Guidance and was enriched with the analysis of the PE initiatives and the PE expertise of stakeholders. Seven key PE Quality Criteria were identified. Public consultation yielded 67 responses from diverse backgrounds. The PE Quality Guidance was agreed to be useful for achieving quality PE in practice, understandable, easy to use, and comprehensive. Overall, eight initiatives from the shortlist and from meeting participants were selected for inclusion in the BOGP based on demonstration of PE Quality Criteria and willingness of initiative owners to collaborate.DiscussionThe PE Quality Guidance and BOGP are practical resources which will be continually updated in response to user feedback. They are not prescriptive, but rather based on core principles, which can be applied according to the unique needs of each interaction and initiative. Implementation of the guidance will facilitate improved and systematic PE across the medicines’ development lifecycle.
In recent years, pharmacovigilance has undergone some major changes. First, the patient’s active role in identifying and describing adverse drug reactions (ADRs) has gained recognition. Second, pharmacovigilance has increasingly incorporated information and communications technology (ICT). Patients can now upload their own reports of ADRs online. Data on intensive medication monitoring are now collected via the Internet and smartphones. Worldwide collection of AEs using smart phones might become the leading technique in Low and Middle Income Countries where broad mobile phone service can be managed cheaper than Internet communication. At the same time, researchers are exploring the potential for data sharing via online forums and Internet search engines. In particular we synthetize the Pros and cons of the various methods for gathering pharmacovigilance data (i.e., Web-based spontaneous reporting of adverse drug reactions; Intensive drug monitoring studies; Analysis of online forum postings; Use of mobile phone systems to monitor drug effects). This article describes these advances and highlights their respective contributions.
Background The effective impact of patient engagement (PE) across the medicines development continuum is widely acknowledged across diverse health stakeholder groups, including health authorities; however, the practical applications of how to implement meaningful and consistent PE are not always addressed. Guidance for the practical implementation of PE requires granularity, and the need for such guidance has been identified as a priority. We describe the co-production and summarize the content of how-to guides that focus on PE in the early stages of medicines development. Methods Multi-stakeholder working groups (WGs) were established by Patient Focused Medicines Development (PFMD) for how-to guide development. How-to guides were co-produced with patients for PE activities identified as priorities through public consultation and by WGs. Guides were developed by applying PE quality guidance and associated quality criteria in an iterative process. How-to guides underwent internal review and validation by experts (ie, those with relevant experience in the particular PE activity or focus area) in specific focus groups and external review and validation through appropriate events and public consultation. Results Overall, 103 individual contributors from 38 organizations (representing eight stakeholder groups, including patients/patient organizations) and from 14 countries were organized into WGs and workstreams. Each WG comprised 15–30 contributors with PE experience relevant to the specific how-to guide. How-to guides were developed for PE in the early discovery and preclinical phases; PE in the development of a clinical outcomes assessment strategy; and PE in clinical trial protocol design. The how-to guides have a standardized format and structure to promote user familiarity. They provide detailed guidance and examples that are relevant to the individual PE activity and aim to facilitate the practical implementation of PE. Conclusions The how-to guides form a comprehensive series of actionable and stepwise resources that build from and integrate the PE quality criteria across the medicines continuum. They will be made freely available through PFMD’s Patient Engagement Management Suite (pemsuite.org) and shared widely to a variety of audiences in different settings, ensuring access to diverse patient populations. Implementation of these guides should advance the field of PE in bringing new medicines to the market and ultimately will benefit patients. Plain English summary Medicines are developed to help patients improve their health and lives. Many organizations and individuals want to ensure that medicines are developed to meet real patient needs and to address what is most important to patients. Finding out what patients need and what patients want requires good patient engagement, but knowing how to do patient engagement is not always clear. This is because medicines development is complicated, and a lot of different steps, people, and organizations are involved. Patient Focused Medicines Development (PFMD) was established in 2015 to connect individuals and organizations that are committed to making medicines not just for patients but with patients. To do this, PFMD brought together patients and other groups of people with relevant experience and good ideas on how to achieve patient engagement in the real-world setting. Together, PFMD has developed “how-to guides” for patient engagement that cover the main activities along the medicines development process. The guides are free to use and provide practical advice and examples that anyone can use in their patient engagement activities. The how-to guides will also help patients to understand medicines development and how best they can participate in this process to address their needs.
