title: Tolerance of a Salsola kali extract standardized in biological units administered by subcutaneous route. Multicenter study.
abstract: BACKGROUND
  Sensitivity to Salsola kali is a frequent cause of allergic respiratory disease in various regions of Spain. However, there are very few articles in which this allergen has been studied.
  
  
  RESULTS
  In order to evaluate the tolerance of this extract, a prospective study has been performed. This study was observational, multi-centred and open, involving 88 patients with allergic respiratory disease due to sensitivity to Salsola, aged between 5 and 52 years. The administration of the extract was performed subcutaneously, through one of two treatment schedules: cluster (8 doses in 4 visits) or conventional (13 doses in 12 visits). A total of 42 adverse reactions were registered, in 26 patients (35 local reactions in 21 patients and 7 systemic reactions in 6 patients). Among the 7 systemic reactions, 4 were registered with the cluster protocol and 2 with the conventional protocol (p = 0.329). In no patients were serious adverse reactions registered.
  
  
  CONCLUSIONS
  The subcutaneous administration of a Salsola extract is safe and well tolerated, both when administered using a conventional schedule and when using a cluster schedule.
