title: Cockroach allergy and allergen-specific immunotherapy in asthma: potential and pitfalls.
abstract: OBJECTIVE
  To provide a summary and discussion of cockroach allergy and clinical trials of cockroach allergen immunotherapy.
  
  
  RESULTS
  Cockroach allergen exposure among sensitized children is increasingly recognized as a key factor contributing to asthma morbidity. Recent trials suggest that cockroach immunotherapy holds promise as a treatment strategy with studies demonstrating immunomodulatory and clinical effects. However, a few obstacles need to be overcome to realize the full potential of this treatment modality as cockroach-allergic patients often exhibit complex sensitization patterns to multiple cockroach-associated proteins, and an immunodominant allergen has not been identified. These factors have made it difficult to produce standardized cockroach allergen extracts that are potent and provide the broad allergen profiles needed for optimal treatment. There have been important advances in the identification and cloning of cockroach allergens, and several strategies are being developed to provide therapeutic cockroach allergen products with enhanced clinical efficacy.
  
  
  CONCLUSIONS
  Allergen immunotherapy has the capability of modulating the immune response to cockroach allergen and has potential as a valuable treatment modality. Further studies of the clinical efficacy, along with the development of improved therapeutic products, are needed to advance our knowledge and realize the full potential of this promising therapy.
