Summary
This is a retrospective analysis of the clinical evolution of 14 patients diagnosed with allergic rhinoconjunctivitis (AR) and/or allergic asthma (AA) caused by Alternaria alternata, who were attended by the allergology service of Vega Baja Hospital of Orihuela (Alicante, Spain). The purpose was to assess the clinical impact and safety of 1-year of subcutaneous immunotherapy with a polymerized molecular allergoid of Alt a 1. Impact of the treatment on allergic diseases (mean number AR/AA episodes and ARIA/GINA classifications), changes in symptoms and prescribed medication, change in the global subjective clinical status of patients and satisfaction with the treatment were also evaluated.

Adverse reactions were also recorded and analysed. After 1-year of treatment, fewer AR and AA episodes (p < 0.05) and improvements in ARIA/GINA classifications were observed. Significant improvements of symptoms (p < 0.05) and a resulting general reduction of the medication prescribed was also detected. Improvements in the global subjective clinical status and good satisfaction rates were observed. Only 1 patient presented a local and not clinically relevant adverse reaction. The treatment showed promising effects with a significant improvement in the clinical status of all patients with a good safety profile.
