Milk hypersensitivity. I. Pathogenesis and symptomatology.

Area of Science:

• Clinical immunology and allergy
• Gastroenterology
• Pediatric medicine

Background:

• Milk hypersensitivity presents significant health, financial, and social challenges.
• The condition is frequently misdiagnosed due to varied symptoms overlapping with other illnesses.
• Existing knowledge on the pathogenesis of cow's milk allergy (CMA) manifestations remains incomplete.

Purpose of the Study:

• To elucidate the heterogeneous nature of milk hypersensitivity.
• To better understand the diverse symptomatology and underlying pathogenic mechanisms in affected patients.
• To address diagnostic challenges and improve clinical management strategies for milk hypersensitivity.

Main Methods:

• Review of recent scientific literature on milk hypersensitivity.
• Analysis of clinical case studies and diagnostic criteria.
• Exploration of immunological and molecular pathways involved in CMA.

Main Results:

• Recent research confirms significant heterogeneity among patients with milk hypersensitivity.
• Varied clinical presentations and distinct pathogenic mechanisms are observed.
• Diagnostic difficulties are highlighted, contributing to under- or overdiagnosis.

Conclusions:

• Cow's milk allergy (CMA) patient populations are diverse in their symptoms and disease mechanisms.
• Further research is crucial to refine diagnostic approaches and therapeutic interventions.
• Recognizing patient heterogeneity is key to improving the management of milk hypersensitivity.
