Heterogeneous validity of daily data on symptoms of seasonal allergic rhinitis recorded by patients using the e-diary AllergyMonitor®

Background: Patient-generated symptom and medication scores are essential for diagnostic and therapeutic decisions in seasonal allergic rhinitis (SAR). Previous studies have shown solid consistencies between different scores at population level in real-life data and trials. For clinicians, the evaluation of individual data quality over time is essential to decide whether to rely on these data in clinical decision-making. Objective: To analyze the consistency of different symptom (SS) and symptom medication scores (SMSs) at individual level in two study cohorts with different characteristics and explore individual patient trajectories over time. Methods: Within the pilot phase of the @IT.2020 project on diagnostic synergy of mobile health and molecular IgE assessment in patients with SAR, we analyzed data of 101 children and 93 adults with SAR and instructed them to record their symptoms and medication intake daily via the mobile app AllergyMonitor®. We then assessed the correlation between different SMS and a visual analogue scale (VAS) on the impact of allergy symptoms on daily life at population and individual level. Results: At population level, the Rhinoconjunctivitis total symptom score (RTSS) correlated better with VAS than the combined symptom and medication score (CSMS). At individual level, consistency among RTSS and VAS was highly heterogeneous and unrelated to disease severity or adherence to recording. Similar heterogeneity was observed for CSMS and VAS. Conclusions: The correlation of clinical information provided by different disease severity scores based on data collected via electronic diaries (e-diaries), is sufficient at population level, but broadly heterogeneous for individual patients. Consistency of the recorded data must be examined for each patient before remotely collected information is used for clinical decision making

Fluids in acute respiratory distress syndrome: pros and cons

PURPOSE OF REVIEW: Fluid resuscitation in acute respiratory distress syndrome (ARDS) is not well documented. Clinical evidence comes from studies in critically ill patients, but these patients respond differently to fluids depending on the presence or absence of sepsis. RECENT FINDINGS: Clinical trials have shown adverse effects on kidney and hemostatic functions and trends toward increased mortality after hydroxyethyl starch infusion. Although well conducted, the methodology deserves attention concerning the infused volume, hemodynamic goals and the presence of septic and nonseptic patients. Small single-center studies have shown beneficial results associated with colloidal molecules through innovative methodological apparatus. Ongoing clinical trials allied to retrospective and prospective trials may favor the introduction of albumin in the critically ill population. SUMMARY: In order to evaluate the pros and cons of using fluids in ARDS patients, it is important to carefully analyze the latest trials. Recent studies have emphasized the importance of better understanding endothelial pathophysiology during fluid management in ARDS patients. Certainly, further studies analyzing fluid strategies in septic and nonseptic ARDS patients are needed
