Current and Potential Biologic Drugs for the Treatment of Chronic Urticaria

This article reviews biologic treatments that are currently applied for the treatment of severe chronic urticaria. Monoclonal anti-immunoglobulin E (omalizumab) is effective and safe in many patients, but accessibility and cost constitute barriers to its wider use. Questions on the optimal duration of the treatment and possible symptom recurrences after discontinuing the drug are still raised. A discussion is presented about several other biologics currently under investigation with potential to be incorporated in the near future in patients with severe chronic urticaria.

Allergy training and immunotherapy in Latin America: results of a regional overview

BACKGROUND

One main practice gap in allergology that has been detected in several regions of the world is the application of specific immunotherapy (SIT). The prescription and practice of SIT should characterize allergologic specialists, but there are regional discrepancies in such practice. A detailed knowledge of the regulatory and legislation aspects and drawbacks would help improve and harmonize SIT practice.

OBJECTIVE

To describe in Latin America the level of allergy training and the characteristics of the use of SIT, including the medical and legal aspects.

METHODS

Three sources were used: a 24-item questionnaire sent to 22 allergologic leaders in 11 Latin American countries, 2 face-to-face meetings, and information from health authorities involved in the approval of medical substances.

RESULTS

In 56% of countries, the specialty of allergology is a third-level care specialty and/or a subspecialty. Two countries have a special training program for pediatric allergists. Passing a board examination is mandatory in 3 countries, and recertification every 2 to 5 years occurs without examination. Sublingual and subcutaneous SITs are available in all Latin American countries. No legislation restricts SIT prescription and it can be performed by nonspecialists in 7 of 11 countries. In 90% of countries, allergists use allergen extracts from the United States (subcutaneous immunotherapy) and Europe (sublingual and subcutaneous immunotherapies), and 50% also manufacture extracts locally. Only 1 country has legal requirements for the quality of raw materials.

CONCLUSION

The present analysis helps to identify gaps in the field of allergologic training and SIT in Latin America, many of them amendable.

100 years of immunotherapy: the Monaco charter. under the high patronage of His Serene Highness Prince Albert II of Monaco

Aims of the Monaco Charter: (1) to present the current evidence on the efficacy and safety of allergen-specific immunotherapy (SIT) and to address the reasons for its underuse in clinical practice; (2) to develop strategies to increase the awareness about the benefits and the hazards of SIT in allergic patients, lay public and healthcare professionals not trained in allergy, and (3) to make SIT accessible and affordable to eligible patients.
