  • Slide 56 - CONCLUSIONS Patients with rhinitis should be investigated also for asthma Uncontrolled Rhinitis may affect the severity/control of co-morbid asthma. In patients with rhinitis and asthma, treating rhinitis can improve asthma. Specific immunotherapy, either SCIT or SLIT, is of benefit also for asthma.
  • Slide 57 - ARIA RECOMMENDATIONS 1- Patients with persistent AR must be assessed for asthma 2- Patients with asthma should be assessed for rhinitis 3- The optimal strategy must combine the treatment of lower and upper airways, aslo in terms of safety and costs
