Serum total IgE and specific IgE to Dermatophagoides pteronyssinus, but not eosinophil cationic protein, are more likely to be elevated in elderly asthmatic patients.

Serum IgE (total and five specific) and eosinophil cationic protein (ECP) levels were compared in elderly physician-diagnosed patients with asthma with non-asthmatic controls matched by age and gender to ascertain whether elevated levels are indicators of asthma in the elderly. All subjects and controls were non-smokers. The subjects were participants in the Florida Geriatric Research Program (FGRP), a longitudinal aging study that tracks the health status of people 65 years and older.

Visceral sensitivity in gastroesophageal reflux.

Symptomatic gastroesophageal reflux disease (GERD) is characterized by a wide spectrum of symptoms. The variance of GERD symptoms may be due to a decreased threshold for symptom elicitation/perception described as "visceral sensitivity." In this study GERD symptoms were scored for presence/frequency.
