Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Current Medication Use Three Years After Diagnosis of AR
Tijdsspanne: 3 years after starting SCIT
|
Percentage patients in both groups that still use medication for their allergic rhinitis symptoms, 3 years after starting their therapy (non IT-group vs IT-group)
|
3 years after starting SCIT
|
|
Degree of Symptom Control 3 Years After IT or 3 Years After Medical Treatment With VAS of Total Nasal Symptom < 5/10 Defined as a Controlled Situation.
Tijdsspanne: 3 years after diagnosis
|
Visual analogue scale (VAS) scores for TNS experienced during the last 4 weeks.
Visual analog scales (VAS) have been used to rate the presence of symptoms or impairment of the daily activities.
Patients had to answer each question by indicating a position with a vertical line between two endpoints, 0 cm for not bothersome versus 10 cm for extremely bothersome.
In this way each question is scored between 0 and 10 points.

|---|---|---|
|
Percentage of Patients Having Controlled Allergic Rhinosinusitis (AR) Symptoms 3 Years After Starting Treatment
Tijdsspanne: 3 years after starting SCIT
|
Based on the proposed cut-off value of VAS < 5/10 for total nasal symptoms (TNS), rhinitis was considered as being controlled in 69 IT patients (84%) versus 223 (63%) non-IT patients
|
3 years after starting SCIT
|
|
Percentage of Patients That Met ARIA Criteria for Mild AR Symtoms at a Mean Interval of 3 Years After Diagnosis
Tijdsspanne: 3 years after diagnosis
|
ARIA classification of AR is made by duration and severity of AR symptoms. Here are calculated the number of patients having mild acute rhinitis. Clinical practice guidelines such as the Allergic Rhinitis and its Impact on Asthma (ARIA) document focus on the quality of life as a principal consideration in assessment and treatment of AR |
