RHINASTHMA-Children: A new quality of life tool for patients with respiratory allergy

International consensus statement on allergy and rhinology: Allergic rhinitis - 2023

BACKGROUND

In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document.

METHODS

ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work.

RESULTS

ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost.

CONCLUSION

The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

Rhinitis and Asthma Patient Perspective (RAPP): Clinical Utility and Predictive Value

BACKGROUND

RhinAsthma Patient Perspective (RAPP) is the only validated tool for assessing of health-related quality of life (HRQoL) related to asthma and rhinitis in individual patients.

OBJECTIVE

To compare the HRQoL burden among countries and explore the usefulness of RAPP as a complementary measure in disease management.

METHODS

In this post hoc analysis of the RAPP International Study, the enrolled population was clustered into patients with controlled rhinitis and controlled asthma (CA/CR), uncontrolled rhinitis and controlled asthma (CA/UR), controlled rhinitis and uncontrolled asthma (UA/CR), and uncontrolled rhinitis and uncontrolled asthma (UA/UR).

RESULTS

We recruited 575 adult patients. Significant differences among countries were observed in the mean RAPP score (from 15.7 in Spain to 18.7 in the Philippines) although the percentage of subjects with an optimal HRQoL (RAPP <15) was not significantly different. Compared with patients with AR and asthma disease control, those with UR/CA, CR/UA, and UR/UA had significantly higher RAPP scores (4.7, 5, and 9.8, respectively). The best cutoffs for detecting uncontrolled diseases were RAPP of 15 or greater (SE = 75%; specificity = 69%; and area under the receiver operating characteristic curve [AUC] = 0.78) for AR; RAPP of 16 or greater (SE = 78%; specificity = 76%; and AUC = 0.83) for asthma; and RAPP of 18 or greater (SE = 86%; specificity = 87%; and AUC = 0.92) for both AR and asthma.

CONCLUSIONS

These findings provide a better understanding of the individual burden of HRQoL related to asthma and rhinitis in daily practice. In addition, the RAPP estimates how much of the risk for uncontrolled disease depends on uncontrolled AR and asthma, allowing its use as a clinical support tool in clinical management.

Allergic rhinitis

Allergic rhinitis (AR) is caused by immunoglobulin E (IgE)-mediated reactions to inhaled allergens and is one of the most common chronic conditions globally. AR often co-occurs with asthma and conjunctivitis and is a global health problem causing major burden and disability worldwide. Risk factors include inhalant and occupational allergens, as well as genetic factors. AR impairs quality of life, affects social life, school and work, and is associated with substantial economic costs. The Allergic Rhinitis and its Impact on Asthma (ARIA) initiative classified AR into intermittent or persistent and mild or moderate/severe. The diagnosis is based on the clinical history and, if needed in patients with uncontrolled rhinitis despite medications or with long-lasting symptoms, on skin tests or the presence of serum-specific IgE antibodies to allergens. The most frequently used pharmacological treatments include oral, intranasal or ocular H₁-antihistamines, intranasal corticosteroids or a fixed combination of intranasal H₁-antihistamines and corticosteroids. Allergen immunotherapy prescribed by a specialist using high-quality extracts in stratified patients is effective in patients with persistent symptoms. Real-world data obtained by mobile technology offer new insights into AR phenotypes and management. The outlook for AR includes a better understanding of novel multimorbid phenotypes, health technology assessment and patient-centred shared decision-making.

RAPP-children: A new tool for assessing quality of life in patients with asthma and rhinitis

BACKGROUND

RhinAsthma Patient Perspective (RAPP) is a short, validated questionnaire for assessing health-related quality of life (HRQoL) in adult patients with comorbid asthma and rhinitis, while a paediatric version is still not available.

OBJECTIVE

The current study aimed to develop and validate the RAPP-children questionnaire.

METHODS

RAPP-children was derived by combining RhinAsthma-children subscales into five unique items. At baseline (T0) and after 30 days (T1), 150 children (6-11 years) with comorbid asthma (predominantly intermittent or mild persistent) and rhinitis were given the following: RAPP-children, RhinAsthma-children, Paediatric Asthma Quality of Life Questionnaire (PAQLQ, age >6 years), Paediatric Rhinoconjunctivitis Quality of Life Questionnaire (PRQLQ), Childhood Asthma Control Test (CACT), KiddyKindl^® (age 6 years) or KidKindl^® (age >6 years), and a Visual Analogue Scale for nasal symptoms (VAS). At the final visit, a Global Rating of Change (GRC) scale was administered. The approved study was registered on the central registration system ClinicalTrials.gov (ID: NCT03276416).

RESULTS

RAPP-children fairly reproduced RhinAsthma-children scores (concordance correlation coefficients between 0.91 and 0.95). RAPP-children showed adequate convergent validity (absolute Spearman's rho larger than 0.5 with PAQLQ, PRQLQ, CACT, KiddyKindl/KidKindl, and VAS), internal consistency (Cronbach's alpha > 0.70), repeatability (intra-cluster correlation coefficient between 0.61 and 0.8) in the presence of clinical stability (GRC = 0), discriminant validity (sensitivity to asthma control status and rhinitis severity), and sensitivity to symptom improvements (GRC > 1). The minimal important difference (MID) was -20. Floor and ceiling effects were minimal. RAPP-children showed fair usability also in younger children (6-8 years).

CONCLUSION & CLINICAL RELEVANCE

RAPP-children is a valid, five-item questionnaire for assessing HRQoL in children aged 6 to 11 years with concomitant asthma and rhinitis. Although further investigation is required in moderate and severe asthmatics, this tool can be useful in clinical trials and in routine medical practice for improving the management of respiratory allergy in children.
