Which of the following allergies is a contraindication for HLA viscosupplementation?

HLA viscosupplementation is a treatment primarily used for osteoarthritis, involving the injection of hyaluronic acid derived from biological sources. The specific contraindication for this procedure relates to the potential for allergic reactions. In this context, avian allergies are particularly significant because many of the products used in HLA viscosupplementation are derived from rooster combs or other avian sources. Individuals with avian allergies may have hypersensitivity to these biologic materials, which poses a risk during the treatment.

In contrast, while shellfish, peanut, and nut allergies can provoke serious allergic reactions, they are typically not directly related to the composition of HLA viscosupplementation products, which do not contain components derived from these sources. Therefore, a history of shellfish, peanut, or nut allergies would not necessarily preclude a patient from safely receiving HLA viscosupplementation, as these allergies do not intersect with the avian-derived components that are the focus of concern.

Thus, individuals with avian allergies should avoid HLA viscosupplementation to minimize the risk of an allergic reaction, making it the specific contraindication in this scenario.
