Insights
This study on allergic disorders in Mexico City found high rates of Staphylococcus aureus and eosinophilia, particularly in children. Findings highlight a strong family history link and suggest these factors are associated with allergic conditions.
Area of Science:
- Allergy and Immunology
- Clinical Medicine
- Epidemiology
Context:
- Allergic disorders represent a significant global health burden.
- Understanding their distribution and features is crucial for effective healthcare planning.
- Mexico City, a major urban center, presents a unique demographic for such studies.
Purpose:
- To describe the distribution and characteristics of allergic disorders.
- To identify key clinical and demographic features in a tertiary hospital setting.
- To investigate associations between eosinophilia, Staphylococcus aureus, and family history in allergic patients.
Summary:
- A one-year descriptive study analyzed 1486 patients, with a near-equal gender distribution and a peak incidence in children under 10.
- Peripheral and nasal eosinophilia were prevalent (57.6% and 58.1%, respectively).
- High rates of Staphylococcus aureus (55% in positive throat cultures) and significant atopic family history (44%) were observed, with rhinitis and asthma being the most common diagnoses.
Impact:
- The study identifies a high prevalence of Staphylococcus aureus and eosinophilia in patients with allergic disorders.
- It underscores the importance of family history in the development of allergies.
- Findings provide valuable data for allergy management and research in Mexico City.
Abstract:
With the aim to know both the distribution and features of allergic disorders in a third level hospital at Mexico city we performed a descriptive study throughout one year, patients data were obtained from their clinical records at initial evaluation. We attended 1486 patients, 744 females (50.1%) and 742 males (49.9%). Children under 10 years-old were the main ages group (46.8%). Forty-four percent of the patients had at least one atopic relative, one brother or sister in 19.5%. White blood cells results showed peripheral cosinophilia in 57.6% patients and nasal cosinophilia in 58.1%. We found S. aureus, coagulase positive in 55% of 192 positive throat cultures. The more frequent diagnoses were rhinitis and asthma (46.3%), rhinitis (20.7%) and asthma (14.1%). We consider that the more prominent findings were the high index of S. aureus, higher atopic family history in brothers and the association between cosinophilia and allergic disorders.
