Background
The relationship between histologic disease activity in eosinophilic esophagitis (EoE) and generic measures of quality of life (QoL) is unclear.
Aims
To determine differences in QoL in adults with EoE based on histologic activity and assess changes in QoL over time.
Methods
We performed an analysis of prospectively collected data from patients in the University of North Carolina EoE Registry. Patients were categorized with histologically active (≥ 15 eosinophils per high-power field [eos/hpf]) or inactive (< 15 eos/hpf) disease. Dysphagia severity was measured with a Likert scale. QoL was measured with 36-Item Short Form (SF-36), compared between active and inactive groups, and assessed longitudinally.
Results
Of 147 EoE cases, those with inactive disease (n = 56) reported less dysphagia severity (3.2 vs. 1.9; p = 0.003) and had lower endoscopic severity (3.8 vs. 1.0; p < 0.001) than those with active disease (n = 91). While SF-36 scores did not differ between active and inactive status, lower mental component scores (MCS) were seen in patients treated with empiric dietary elimination (44.9 vs. 50.8; p = 0.005). Dysphagia severity was negatively correlated with both physical component score (PCS) (r = −0.33; p < 0.001) and MCS (r = −0.18; p = 0.03). Despite more cases achieving histologic response over time, SF-36 scores did not improve on either raw or adjusted analyses.
Conclusion
QoL measured by SF-36 in EoE was similar regardless of histologic disease activity and was in the range of population averages. General QoL metrics like the SF-36 do not appear to have substantial utility in EoE.
