Background: The Allergic Rhinitis and its Impact on Asthma (ARIA) guidelines classify rhinitis as "intermittent" or "persistent" and "mild" or "moderate-severe". Objectives: To assess ARIA classes in a real-world study in terms of phenotypic differences and their association with asthma. Methods: We performed a cross-sectional real-world study base...
Article
Biomarkers for the diagnosis, treatment and follow-up of patients with rhinitis and/or asthma are urgently needed. Although some biologic biomarkers exist in specialist care for asthma, they cannot be largely used in primary care. There are no validated biomarkers in rhinitis or allergen immunotherapy (AIT) that can be used in clinical practice. Th...

Contact with natural environments enriches the human microbiome, promotes immune balance and protects against allergies and inflammatory disorders. In Finland, the allergy & asthma epidemic became slowly visible in mid 1960s. After the World War II, Karelia was split into Finnish and Soviet Union (now Russia) territories. This led to more marked en...

Aim: The efficacy and safety of allergen immunotherapy (AIT) in allergic rhinitis has been classically assessed using randomized controlled trials (RCTs). However, RCTs may have limitations in their external validity, and their evidence may be complemented with that from real-world studies. We aimed to review the mHealth apps that can be used for...
Article
Full-text available
Background: Validated questionnaires are used to assess asthma control over the past 1-4 weeks from reporting. However, they do not adequately capture asthma control in patients with fluctuating symptoms. Using the Mobile Airways Sentinel Network for airway diseases (MASK-air) app, we developed and validated an electronic daily asthma control scor...
Article
Most previous studies assessing multimorbidity in asthma assessed the frequency of individual comorbid diseases. We aimed to assess the frequency and clinical and economic impact of co-occurring groups of comorbidities (comorbidity patterns using the Charlson Comorbidity Index) on asthma hospitalizations. We assessed the dataset containing a regist...
Article
Background: Understanding differences in sensitization profiles at the molecular allergen level is important for diagnosis, personalised treatment and prevention strategies in allergy.

Digital health includes eHealth and areas such as the use of advanced computer sciences. eHealth comprises several components, including electronic health records, telehealth, and mHealth. mHealth is segmented into mHealth apps, mHealth services, and medical devices. The present paper is not intended to provide a systematic review of the current di...
Conference Paper
Patient-reported outcome measures (PROMs) are a set of tools that allow clinicians to obtain information about the health status of their patients and help understand the impact of disease, treatment outcomes, patient satisfaction and awareness of the disease. However, patient-centered care may differ from private versus the public sphere in many c...
Article
Background: In clinical and epidemiological studies, cut-offs of Patient-Reported Outcome Measures (PROMs) can be used to classify patients into groups of statistical and clinical relevance. However, visual analog scale (VAS) cut-offs in MASK-air® have not been tested. Objective: To calculate cut-offs for VAS global, nasal, ocular, and asthma sy...
Article
Many studies exploring the factors associated with asthma-specific quality of life (QOL) have shown that asthma control is the main predictor of asthma-related QOL. However, to the best of our knowledge, no study has ever explored the individual impact of the five main symptoms of asthma (wheezing, dyspnea, chest tightness, cough and airway secreti...

Full-text available
Introduction Data from mHealth apps can provide valuable information on rhinitis control and treatment patterns. However, in MASK‐air®, these data have only been analyzed cross‐sectionally, without considering the changes of symptoms over time. We analyzed data from MASK‐air® longitudinally, clustering weeks according to reported rhinitis symptoms....

Purpose of review: Anaphylaxis is common in old-age adults but is insufficiently understood by physicians, and may be underdiagnosed. This review discusses the specificities of anaphylaxis in this age group and stresses the importance of adrenaline in its management. Recent findings: Data from the European Anaphylaxis Registry on elderly patient...
Article
Introduction: Allergic rhinitis (AR) is a disease characterized by IgE-mediated hypersensitivity responses akin to allergic asthma. Although common in children and young adults, AR can be particularly vexing in the elderly: several studies have underlined its impact on the patient's self-perceived health-related quality of life (HR-QoL). Available...

We report a case of severe uncontrolled allergic and eosinophilic asthma in which omalizumab had led to a fast remission. After 18 months, mepolizumab was added to omalizumab because of increased blood eosinophils and a deterioration of asthma control. Asthma was then under control for the next 18 months. Discontinuation of mepolizumab in the ensui...

Abstract: Background Cough features a complex peripheral and central neuronal network. The function of the chemosensitive and stretch (afferent) cough receptors is well described but partly understood. It is speculated that chronic cough reflects a neurogenic inflammation of the cough reflex, which becomes hypersensitive. This is mediated by neurom...
