Findings from Research

The Rhinitis Control Assessment Test (RCAT) was developed through a qualitative process involving 39 patients in focus groups and 23 in cognitive interviews, aiming to create a tool for better monitoring of allergic rhinitis symptoms.

The draft instrument includes 26 items that assess various aspects of rhinitis control, such as symptom frequency, impact on activities, and medication use, with a five-point response scale and a one-week recall period, which were chosen based on patient feedback.

The NEUROMARK® system, a radiofrequency ablation device, was found to be safe and effective for treating chronic rhinitis, with no serious adverse events reported during the study involving 36 participants.

At 3 months post-treatment, participants showed significant improvements in nasal symptoms, with a 53% reduction in rhinorrhea and a 55% reduction in nasal congestion, along with a high responder rate of 78% for overall symptom relief.

In a study involving 30 patients (15 with allergic rhinitis and 15 with idiopathic rhinitis), nerve growth factor (NGF) levels were significantly higher in patients with allergic rhinitis, suggesting a link between NGF and the severity of symptoms.

Increased perivascular innervation was associated with more intense clinical symptoms, indicating that NGF produced by inflammatory cells may stimulate nerve growth, contributing to the heightened symptoms observed in allergic rhinitis.

The Rhinitis Control Assessment Test (RCAT) is a reliable and valid tool for evaluating rhinitis symptom control, with internal consistency and test-retest reliability scores of 0.77 and 0.78, respectively, based on a study of 402 patients aged 12 and older.

A cut-point score of 21 or less on the RCAT can effectively identify patients with rhinitis symptom control issues, and the minimal important difference (MID) was estimated to be 3 points, making it a practical tool for clinical use.

The Brazilian Portuguese version of the Rhinitis Control Assessment Test (RCAT) was validated with a study involving 141 adolescents with allergic rhinitis, showing good internal consistency (0.73) and significant correlations with nasal symptoms and airflow measurements.

Using a cutoff score of 22 on the RCAT effectively distinguished between controlled and uncontrolled allergic rhinitis, indicating its utility as a reliable tool for assessing rhinitis control in this population.

The Rhinitis Control Assessment Test (RCAT) is a simple, self-administered questionnaire designed to help both physicians and patients assess and understand rhinitis control, making it easier to monitor symptoms over time.

By providing a clear rhinitis score, the RCAT aims to improve the quality of care for patients suffering from allergic and nonallergic rhinitis, addressing the complex nature of managing this condition.

In a study of Artemisia pollen allergic patients undergoing at least 1 year of allergen immunotherapy (AIT), only those who responded to treatment showed elevated levels of specific IgE and IgG4, indicating a potential link between these antibodies and successful AIT outcomes.

The study identified leukotriene A4 hydrolase (LTA4H) as a promising biomarker for predicting AIT effectiveness, with significant increases in LTA4H levels observed in responders after treatment, suggesting it could help select patients who are likely to benefit from AIT.
