Surface Co-Expression of Two Different PfEMP1 Antigens on Single Plasmodium falciparum-Infected Erythrocytes Facilitates Binding to ICAM1 and PECAM1

The Plasmodium falciparum erythrocyte membrane protein 1 (PfEMP1) antigens play a major role in cytoadhesion of infected erythrocytes (IE), antigenic variation, and immunity to malaria. The current consensus on control of variant surface antigen expression is that only one PfEMP1 encoded by one var gene is expressed per cell at a time. We measured var mRNA transcript levels by real-time Q-PCR, analysed var gene transcripts by single-cell FISH and directly compared these with PfEMP1 antigen surface expression and cytoadhesion in three different antibody-selected P. falciparum 3D7 sub-lines using live confocal microscopy, flow cytometry and in vitro adhesion assays. We found that one selected parasite sub-line simultaneously expressed two different var genes as surface antigens, on single IE. Importantly, and of physiological relevance to adhesion and malaria pathogenesis, this parasite sub-line was found to bind both CD31/PECAM1 and CD54/ICAM1 and to adhere twice as efficiently to human endothelial cells, compared to infected cells having only one PfEMP1 variant on the surface. These new results on PfEMP1 antigen expression indicate that a re-evaluation of the molecular mechanisms involved in P. falciparum adhesion and of the accepted paradigm of absolutely mutually exclusive var gene transcription is required

Research priorities for children's cancer : a James Lind Alliance Priority Setting Partnership in the UK

OBJECTIVES: To engage children who have experienced cancer, childhood cancer survivors, their families and professionals to systematically identify and prioritise research questions about childhood cancer to inform the future research agenda. DESIGN: James Lind Alliance Priority Setting Partnership. SETTING: UK health service and community. METHODS: A steering group oversaw the initiative. Potential research questions were collected in an online survey, then checked to ensure they were unanswered. Shortlisting via a second online survey identified the highest priority questions. A parallel process with children was undertaken. A final consensus workshop was held to determine the Top 10 priorities. PARTICIPANTS: Children and survivors of childhood cancer, diagnosed before age 16, their families, friends and professionals who work with this population. RESULTS: Four hundred and eighty-eight people submitted 1299 potential questions. These were refined into 108 unique questions; 4 were already answered and 3 were under active study, therefore, removed. Three hundred and twenty-seven respondents completed the shortlisting survey. Seventy-one children submitted questions in the children's surveys, eight children attended a workshop to prioritise these questions. The Top 5 questions from children were taken to the final workshop where 23 questions in total were discussed by 25 participants (young adults, carers and professionals). The top priority was 'can we find effective and kinder (less burdensome, more tolerable, with fewer short and long-term effects) treatments for children with cancer, including relapsed cancer?' CONCLUSIONS: We have identified research priorities for children's cancer from the perspectives of children, survivors, their families and the professionals who care for them. Questions reflect the breadth of the cancer experience, including diagnosis, relapse, hospital experience, support during/after treatment and the long-term impact of cancer. These should inform funding of future research as they are the questions that matter most to the people who could benefit from research

From protocol to published report:a study of consistency in the reporting of academic drug trials

BACKGROUND: Unacknowledged inconsistencies in the reporting of clinical trials undermine the validity of the results of the trials. Little is known about inconsistency in the reporting of academic clinical drug trials. Therefore, we investigated the prevalence of consistency between protocols and published reports of academic clinical drug trials. METHODS: A comparison was made between study protocols and their corresponding published reports. We assessed the overall consistency, which was defined as the absence of discrepancy regarding study type (categorized as either exploratory or confirmatory), primary objective, primary endpoint, and – for confirmatory trials only – hypothesis and sample size calculation. We used logistic regression, χ(2), and Fisher’s exact test. RESULTS: A total of 282 applications of academic clinical drug trials were submitted to the Danish Health and Medicines Authority in 1999, 2001, and 2003, 95 of which fulfilled the eligibility criteria and had at least one corresponding published report reporting data on trial subjects. Overall consistency was observed in 39 % of the trials (95 % CI: 29 to 49 %). Randomized controlled trials (RCTs) constituted 72 % (95 % CI: 63 to 81 %) of the sample, and 87 % (95 % CI: 80 to 94 %) of the trials were hospital based. CONCLUSIONS: Overall consistency between protocols and their corresponding published reports was low. Motivators for the inconsistencies are unknown but do not seem restricted to economic incentives

Effect of European Clinical Trials Directive on academic drug trials in Denmark: retrospective study of applications to the Danish Medicines Agency 1993-2006

Objective To determine the impact of the European Union’s Clinical Trials Directive on the number of academic drug trials carried out in Denmark

Methodological characteristics of academic clinical drug trials--a retrospective cohort study of applications to the Danish Medicines Agency 1993-2005

AIM: The aim of this study was to investigate the temporal trends in characteristics of academic clinical drug trials. We here report characteristics on trial methodology. METHODS: A review of 386 approved applications of academic clinical drug trials submitted to the Danish Medicines Agency 1993–2005 was carried out. Data on 11 methodological characteristics were collected, e.g. statement of primary endpoint, use of control group, blinding, randomization, method for generation of allocation sequence, monitoring according to the principles of Good Clinical Practice (GCP monitoring) and publication. RESULTS: Statement of primary endpoint increased from 60 to 90% of trials (P < 0.0001). Comparing the period before and after implementation of the Clinical Trials Directive in 2004, intention of GCP monitoring increased from 13% to 94%. Control of medicine compliance increased from 42% to 76% (P < 0.0001) among trials with self-administration of the investigational medicinal product. Among controlled trials use of randomization increased from 78% to 94% (P= 0.0063) of trials. Remaining characteristics did not change significantly. In total 68% (264/386) were randomized controlled trials. CONCLUSIONS: Our study shows that randomization, definition of primary endpoint, GCP monitoring, and control of medicine compliance form part of a significantly increasing percentage of academic clinical drug trials. This indicates an increase in the quality of academic clinical drug research in Denmark 1993–2005. However, high numbers of unblinded randomized controlled trials and randomized controlled trials utilizing unacceptable methods for generation of allocation sequence emphasize the potential for further improvement of trial methodology
