RESUMEN
INTRODUCTION: Drug efficacy and effectiveness are assessed respectively through clinical trials and pharmaco-epidemiological studies. However, relative and absolute benefits of drugs are distinct measures that must be considered in relation to the baseline risk of disease incidence, complication or progression. On the other hand, adverse drug reactions are independent of the basic risk but depend on the characteristics of the population treated. Given these prerequisites, how can we balance the benefits and risks of drugs? AREAS COVERED: We use the example of therapeutics evaluated during Covid to describe how assessing the benefit-risk balance of drugs is a complex process. EXPERT OPINION: Clinical trials are not designed to identify rare adverse events, underscoring the necessity for a pharmacovigilance system. Evaluating the balance between the benefits and risks of drugs is an ongoing process, demanding the simultaneous analysis of data from clinical trials, potential drug-drug interactions, pharmacovigilance monitoring and pharmaco-epidemiological studies, to identify potential safety concerns. In addition, pharmacologists must play a major role in educating the general public about drugs, aiding in the accurate interpretation of the benefit-risk balance and preventing misinformation.

Half of severely asthmatic adolescents treated with omalizumab transitioning to adulthood discontinue the treatment, suggesting insufficient asthma control. However, most of the other half have low rates of HCRU markers, their asthma being under control. https://bit.ly/49ixpxt.
RESUMEN
BACKGROUND: The only causal treatment for allergic rhinitis (AR) is allergen immunotherapy (AIT) including personalized liquid sublingual AIT (SLIT). We present the methodology for establishing the EfficAPSI cohort to further evaluate the real-life effectiveness and use of SLIT liquid. RESEARCH DESIGN AND METHODS: The EfficAPSI cohort was constituted by deterministic linkage of Stallergenes Greer dispensing and nationwide French healthcare insurance system (SNDS) databases. Data from 2006 to 2018 were extracted. All patients who initiated Stallergenes Greer SLIT liquid between 2010 and 2013 were considered as exposed and those dispensed with AR symptomatic treatment only as control. To limit the impact of confounding, the models will be weighted using the inverse probability of treatment weighting (IPTW). RESULTS: A total of 445,574 patients were included; median age was 38 years; 59.1% were female. Exposed patients (n = 112,492) were significantly younger, more frequently males, and less likely to have comorbidities than controls (n = 333,082). After IPTW, patients' characteristics from both groups were similar. CONCLUSIONS: To date, the EfficAPSI cohort has the largest number of person-years of follow-up in the field of AIT. The completeness of the data allows to evaluate SLIT liquid effectiveness with rigorous methodology, leading to important insights on personalized medicine in real-life.

Background: The only disease-modifying treatment currently available for allergic rhinitis (AR) is allergen immunotherapy (AIT). The main objective of the EfficAPSI real-world study (RWS) was to evaluate the impact of liquid sublingual immunotherapy (SLIT-liquid) on asthma onset and evolution in AR patients. Methods: An analysis with propensity score weighting was performed using the EfficAPSI cohort, comparing patients dispensed SLIT-liquid with patients dispensed AR symptomatic medication with no history of AIT (controls). Index date corresponded to the first dispensation of either treatment. The sensitive definition of asthma event considered the first asthma drug dispensation, hospitalisation or long-term disease (LTD) for asthma, the specific one omitted drug dispensation and the combined one considered omalizumab or three ICS ± LABA dispensation, hospitalisation or LTD. In patients with pre-existing asthma, the GINA treatment step-up evolution was analysed. Findings: In this cohort including 112,492 SLIT-liquid and 333,082 controls, SLIT-liquid exposure was associated with a significant lower risk of asthma onset vs. control, according to all definitions (combined: HR [95% CI] = 0.62 [0.60-0.63], sensitive: 0.77 [0.76-0.78], and specific: 0.67 [0.61-0.72]). Exposure to SLIT was associated with a one-third reduction in GINA step-up regardless baseline steps. Interpretation: In this national RWS with the largest number of person-years of follow-up to date in the field of AIT, SLIT-liquid was associated with a significant reduction in the risk of asthma onset or worsening. The use of three definitions (sensitive or specific) and GINA step-up reinforced the rigorous methodology, substantiating SLIT-liquid evidence as a causal treatment option for patients with respiratory allergies.

RESUMEN
The increasing role of digital technology, social media, the wide range of channels and the volume of information, the role of medicine as a societal subject, public information that is insufficient and poorly suited to situations of uncertainty are all observations which led to the theme of this round table. After discussing the definition of disinformation, which is not limited to fake news, and talking about contributors who misinform, whether intentionally or not, the participants of this round table made nine recommendations (R) to combat disinformation about health products: create a collaborative platform, information/training on health products, a platform with five major characteristics, namely accessibility, flexibility, objectivity, transparency and independence, as well as media suited to the different targets (R1); promote basic knowledge on health products: education/training to restore the particularly poor image of medication, and teach the public how to use basic concepts appropriately (R2); improve communication to the public based on the observation that information is the main weapon against misinformation and entails, in particular, coordinating communication from the different institutions to make public information more audible, making institutional messages clearer, ensuring they are more factual and prioritising them (R3); know how to communicate using the correct codes and tools (R4), because, to be understood, the substance and the form are inseparable; develop research on communication in the field of health products (R5); acquire tools to identify and regulate as soon as possible (R6); keep check of content by developing critical thinking (R7); define quality criteria for information sources (R8); identify, assess and reference initiatives for the public that could be placed on the platform (R9).
