How Latex Sensitization Intensifies Asthma and Rhinitis New Insights from Côte d’Ivoire

Introduction

Latex, commonly derived from the sap of the Hevea brasiliensis tree, is present in everyday materials from gloves to medical devices. But for individuals predisposed to allergies, especially in resource-limited settings, this widespread substance is not benign. A new study from Côte d’Ivoire underscores how latex sensitization significantly aggravates asthma and rhinitis.

Latex and Allergic Disease Progression

This cross-sectional study tracked 1,860 patients over 12 years at the University Hospital of Cocody. The researchers assessed allergic reactions using prick tests and classified participants based on their sensitization to latex or other allergens.

Key Findings:

• Latex sensitization was identified in 66% of allergic individuals.
• Those with monosensitization to latex had 1.9 times the risk of asthma progression.
• Polysensitized individuals (latex plus other allergens) had an even higher risk 2.7 for asthma and 3.6 for rhinitis.
• Patients exposed to latex occupationally ( healthcare workers) were disproportionately affected.

The Clinical Challenge Latex Avoidance is Not So Simple

Despite global awareness, latex remains difficult to eliminate especially in developing countries like Côte d’Ivoire. The cross-reactivity between latex and certain foods like bananas or avocados complicates diagnosis and avoidance. Moreover, insufficient public education further delays effective management.

The American Academy of Allergy, Asthma & Immunology (AAAAI) emphasizes that allergens like latex are a “persistent threat” due to their presence in consumer and healthcare products, urging comprehensive patient education and preventive policies.

Implications for Patient Care and Public Health

This study’s findings reinforce the need to:

• Integrate latex sensitization status into asthma and rhinitis management strategies.
• Raise awareness about cross-reactive food allergies.
• Implement stricter occupational health measures for at risk professionals.
• Improve public health education regarding allergen exposure.
