Background: Eosinophilic Esophagitis (EoE) is an immune-mediated, chronic, relapsing disease that affects 34.4 people per 100.000 population worldwide. EoE is characterized by an eosinophilic inflammatory infiltrate in the esophageal mucosa which leads to fibro-stenotic esophageal remodeling and esophageal dysfunction symptoms. To induce and maintain disease remission, EoE requires continuous pharmacological treatment and periodic outpatient, endoscopic and histologic follow-up. Aim of the study: the aim of the study is to evaluate EoE patients’ clinical, endoscopic, and histologic response to PPI and/or Topical Corticosteroids treatment and to measure the rate of disease remission in the short-term and mid to long-term. Materials and Methods: the monocentric observational cohort study evaluated 174 EoE patients followed by the Gastroenterology Unit of the University of Padua Hospital from August 2011 to November 2022. Their treatment and subsequent symptomatic, endoscopic (assessed by EREFS score) and histologic (assessed by eosinophil/HPF count) responses were collected. Results: out of 174 EoE patients included in the study, 145/174 (83.3%) were males, with a mean age of 36.7 ± 15.3 years and mean age at diagnosis of 31.1 ± 15.8 years, who had at least one endoscopic and histologic follow-up after treatment. Data on PPI treatment as induction therapy (t1) revealed that endoscopic remission is achieved in 45/109 (41.3%) patients, histologic remission in 44/109 (40.4%) patients and clinical remission in 73/109 (67%) patients. Furthermore, over time (t2, t3, t4), PPIs maintained endoscopic disease remission in 62.1% ± 16.9%, histologic remission in 55.2% ± 28.5% and clinical remission in 80.4% ± 20.9%. Data on TCS treatment as induction therapy (t1) revealed that endoscopic remission was achieved in 11/24 (45.8%) patients, histologic remission in 15/24 (62.5%) patients and clinical remission in 14/24 (58.3%) patients. Furthermore, over time (t2, t3, t4, t5), TCSs maintained endoscopic disease remission in 49.7% ± 29.1%, histologic remission in 58.3% ± 22.7% and clinical remission in 76.8% ± 25.3%. Data on combined treatment (TCS+PPI) as induction therapy (t1) revealed that endoscopic remission was achieved in 20/41 (48.8%) patients, histologic remission in 20/41 (48.8%) patients and clinical remission in 26/41 (63.4%) patients. Furthermore, over time (t2, t3, t4, t5), combined treatment (TCS+PPI) maintained endoscopic remission of disease in 63.9% ± 11.1%, histologic remission in 58.3% ± 22.7% and clinical remission in 72.6% ± 3.9%. Conclusions: our study results confirm the efficacy of PPI and TCS treatment, both as mono-therapy and combined treatment, to induce disease remission in EoE patients, with rates of maintenance clinical, endoscopic and histologic response of about 60% over time. Moreover, our data confirm the high variability in terms of treatment response to current EoE treatments as well as the need of having novel therapeutic options to improve disease management and control.
Background: L’Esofagite Eosinofila (EoE) è una malattia immuno-mediata, cronica e recidivante che colpisce nel mondo 34.4 persone ogni 100.000 abitanti. L’EoE è caratterizzata dall’infiltrazione di granulociti eosinofili a livello della mucosa esofagea che nel tempo porta a un rimodellamento fibro-stenotico, responsabile dei sintomi da disfunzione esofagea. Per andare in remissione, la patologia necessita di un trattamento farmacologico continuo e di un follow-up periodico di tipo ambulatoriale, endoscopico e istologico. Scopo dello studio: lo scopo dello studio è quello di valutare l’outcome clinico, endoscopico e istologico dei pazienti con EoE trattati con PPI, Corticosteroidi Topici o terapia combinata per determinare la percentuale di remissione della malattia nel breve e nel medio-lungo termine. Materiali e metodi: lo studio osservazionale di coorte monocentrico ha valutato pazienti con diagnosi di EoE che hanno intrapreso un percorso di follow-up presso l’U.O.C. di Gastroenterologia di Padova. Di questi pazienti sono stati valutati il trattamento assunto e la successiva risposta sintomatologica, endoscopica (valutata mediante EREFS score) e istologica (valutata mediante numero di eosinofili/HPF). Risultati: sono stati inclusi nello studio 174 pazienti con EoE, di cui 145/174 (83.3%) maschi, con età media di 36.7 ± 15.3 anni ed età media alla diagnosi di 31.1 ± 15.8 anni, i quali si sono sottoposti ad almeno un follow-up endoscopico ed istologico dopo il trattamento. I dati relativi alla terapia di induzione (t1) con PPI hanno messo in luce che la remissione endoscopica si ottiene in 45/109 (41.3%) pazienti, la remissione istologica in 44/109 (40.4%) pazienti e la remissione clinica in 73/109 (67%) pazienti. Inoltre, nel tempo (t2, t3, t4), i PPI hanno mantenuto la remissione endoscopica di malattia nel 62.1% ± 16.9%, la remissione istologica nel 55.2% ± 28.5% e la remissione clinica nel 80.4% ± 20.9%. I dati relativi alla terapia di induzione (t1) con TCS hanno messo in luce che la remissione endoscopica si è ottenuta in 11/24 (45.8%) pazienti, la remissione istologica in 15/24 (62.5%) pazienti e la remissione clinica in 14/24 (58.3%) pazienti. Inoltre, nel tempo (t2, t3, t4, t5), i TCS hanno mantenuto la remissione endoscopica di malattia nel 49.7% ± 29.1%, la remissione istologica nel 58.3% ± 22.7% e la remissione clinica nel 76.8% ± 25.3%. I dati relativi alla terapia di induzione (t1) con trattamento combinato (TCS+PPI) hanno messo in luce che la remissione endoscopica si è ottenuta in 20/41 (48.8%) pazienti, la remissione istologica in 20/41 (48.8%) pazienti e la remissione clinica in 26/41 (63.4%) pazienti. Inoltre, nel tempo (t2, t3, t4, t5), il trattamento combinato (TCS+PPI) ha mantenuto la remissione endoscopica di malattia nel 63.9% ± 11.1%, la remissione istologica nel 58.3% ± 22.7% e la remissione clinica nel 72.6% ± 3.9%. Conclusioni: i risultati dello studio confermano l’efficacia del trattamento con PPI e TCS, in mono-terapia e in combinazione, nell’indurre la remissione della malattia, con tassi di risposta endoscopica, clinica ed istologica che si conservano nel tempo in circa il 60% dei pazienti responsivi. Questi dati confermano inoltre la marcata variabilità di risposta dei pazienti con EoE alle attuali terapie farmacologiche, così come la necessità di nuovi farmaci che possano determinare una risposta clinica ed endoscopica maggiore in induzione e in mantenimento.
