Eye reflux: an ocular extraesophageal manifestation of gastric reflux

A combined treatment for patients with dry eye and associated laryngopharyngeal reflux: a real-life approach

AIM

To evaluate the efficacy and tolerability of administering a combined therapy in patients with dry eye syndrome (DES) and associated laryngopharyngeal reflux (LPR).

METHODS

The study was retrospective, open, observational, and conducted in a real-life setting. Patients had pathological symptom assessment in dry eye (SANDE) and reflux symptom index (RSI) at baseline. Patients were re-assessed after 1mo and at the end of treatment. The treatment consisted of a three-month course based on the combined therapy: Gastroftal eye drops, one drop three times a day, and Gastroftal tablets, two tablets after lunch and two tablets after dinner. Tear break-up-time (TBUT) test, Schirmer test, RSI, and SANDE questionnaire were evaluated.

RESULTS

The study included 253 patients. The mean age was 58±11.19y. TBUT test score and Schirmer's test significantly increased (both P<0.001) after 1mo and at the end of treatment. The RSI score and SANDE scores significantly decreased (both P<0.001) after 1mo and at the end of treatment.

CONCLUSION

The current, retrospective, and open study shows that combined therapy using Gastroftal eye drops and tablets could represent a valuable option in managing patients with DES associated with LPR.

Inflammation and Dry Eye-like Symptoms as Concomitant Manifestations of Laryngo-Pharyngeal Reflux

PURPOSE

Laryngo-pharyngeal reflux (LPR) is a common worldwide disease. LPR symptoms may involve distant organs and tissues including the ocular surface with manifestations of a Dry Eye-like disease. We evaluated the concomitant involvement of the ocular surface in patients with LPR. We also defined the clinical signs and the roles of chemical and neuro-inflammatory mediators in the tears of LPR patients.

METHODS

Seventy-seven patients with LPR (mean age 65.8 ± 16.8 SD) and 25 healthy controls (mean age 56.5 ± 16.3 SD) were recruited from the otorhinolaryngology unit. Each subject was evaluated for the presence of concomitant ocular surface disease through clinical examination, including the measurement of tear break-up time (TBUT) and the Ocular Surface Disease Index (OSDI) questionnaire. Tears and conjunctival imprints were collected. The presence of pepsin in tears was detected by ELISA. HLA-DR in conjunctival imprints were imaged by immunofluorescence microscopy. RT-PCR quantified conjunctival mRNA transcripts of HLA-DR, IL-8, MUC5AC, NADPH, VIP, and NPY.

RESULTS

Patients with LPR had significantly increased OSDI and reduced TBUT scores compared to control subjects (p < 0.05 each). Pepsin was detected in 51% of patient tears while it was not measurable in the controls (p < 0.01). Immunoreactivity for HLA-DR in the conjunctival impressions was greater than for the controls with an increased mRNA expression (p < 0.05). mRNA transcripts for IL-8, NADPH, and VIP were significantly increased in LPR patients (p < 0.05 each), but neither MUC5AC nor NPY were different from controls.

CONCLUSIONS

LPR can adversely affect the ocular surface, leading to moderate signs and symptoms of dry eye. This study provides evidence that the presence of pepsin, HLA-DR immunoreactivity, and increased mRNA expression of neuro-inflammatory markers in the tears and conjunctival imprints of LPR patients suggests a potential link between LPR inflammation and ocular surface disease.

"All that glitters is not gold": sialomegaly, xerostomia, and dry eye is not always Sjögren's syndrome

Although dry mouth, dry eye, and swollen salivary glands are the hallmark manifestations of Sjögren's syndrome (pSS), a wide spectrum of other conditions should be considered for differential diagnosis. The diagnostic challenge is mainly encountered in patients presenting with dry eyes and/or dry mouth, who do not meet the full established classification criteria for pSS. Presented case-based review highlights the relationship between dry eye, parotid swelling, and psychiatric disorders. The obsessive-compulsive disorder may be separately be a cause of dryness symptoms even were not using any psychiatric drugs. The presented review widely discussed this problem and the aim is to shed new light on the interpretation of the dryness symptom and the necessity of individual patient assessment, excluding causes other than pSS before making a final diagnosis and making a decision on the treatment method.

Ocular Involvement of SARS-CoV-2 in a Polish Cohort of COVID-19-Positive Patients

The coronavirus SARS-CoV-2 responsible for the current human COVID-19 pandemic has shown tropism toward different organs with variable efficiency, eyes included. The purpose of this study has been to investigate the presence of detectable SARS-CoV-2 infection in ocular swabs in patients affected by COVID-19. A consecutive series of 74 COVID-19-positive patients (age 21-89) were enrolled at two Polish COVID-19 hospitals for 4 months and were characterized by PCR for the presence of the SARS-CoV-2 genetic material in nasopharyngeal (NP) and ocular swabs, while their respiratory and ocular symptoms were noted. Almost 50% of them presented with severe/critical respiratory involvement, and some degree of eye disease. No tight correlation was observed between the presence of ocular and respiratory symptoms. Three male patients presenting with severe/critical lung disease tested positive in ocular swab, however with mild/moderate ocular symptoms. In conclusion, our study lends further support to the view that overt ocular infection by the SARS-CoV-2 virus is not such a frequent occurrence.

Evidence of Pepsin-Related Ocular Surface Damage and Dry Eye (PROD Syndrome) in Patients with Laryngopharyngeal Reflux

Background: patients with laryngopharyngeal reflux (LPR) showed detectable levels of tear pepsin that explain the nasolacrimal obstruction. The purpose of this study was to determine whether patients with LPR show ocular surface changes and to investigate the relationship between lacrimal pepsin concentration and ocular alterations. Methods: Fifty patients with positive endoscopic signs for LPR and an equal or higher score of 13 and 7 for Reflux Symptom Index and Reflux Finding Score were enrolled. Twenty healthy patients with no reflux disease and dry eye were included as the control group. After evaluation of ocular discomfort symptoms, the tear break-up time test, corneal staining, and tear sampling were performed. Tear pepsin levels were measured using Pep-test^TM kit. Results: Patients with LPR showed ocular surface changes including epithelial damage (48%) and impairment of lacrimal function (72%). Tear pepsin levels were detectable in 32 out of 50 (64%) patients with LPR (mean ± SD: 55.4 ± 67.5 ng/mL) and in none of the control subjects. Most of the LPR patients complained of ocular discomfort symptoms, including itching (38%), redness (56%), or foreign body sensation (40%). Tear pepsin levels were significantly correlated with the severity of LPR disease and with ocular surface changes. Conclusions: A multidisciplinary approach, including ophthalmological evaluation, should be considered in order to improve the management of patients with LPR.

A new therapeutic approach for the Dry Eye Syndrome in patients with laryngopharyngeal reflux: first data

Laryngopharyngeal reflux (LPR) is a common disorder. Pepsin has been detected also at eye level, this was a starting point for newest theories about LPR impact on Dry Eye Syndrome. The current preliminary study compared two treatments in patients with Dry Eye Syndrome and LPR. Patients were treated with Gastroftal eye drops and Gastroftal tablets or hyaluronic acid eye drops for 3 months. The following parameters were evaluated: Ocular Surface Disease Index (OSDI), OSDI categories, Reflux Symptom Index (RSI), Reflux Finding Score (RFS), Fluorescein Tear Breakup Time (B-TUT), and Schirmer test before and after treatment. On the whole, 21 patients were enrolled: 10 were treated with hyaluronic acid Atlantis (Group A) and 11 with Gastroftal eye drops and tablets (Group B). After treatment, in Group A only OSDI significantly diminished (p=0.029); in Group B there were significant reductions concerning OSDI (p=0.0277), OSDI categories (p=0.0211), RSI (p=0.0172), Schirmer test (p=0.0172), T-BUT (p=0.0265), and RFS (p=0.0205). The current preliminary demonstrated that the combined ocular and systemic therapy with hyaluronic acid, Magnesium alginate, Simethicone, and Camelia sinensis may be considered a promising treatment in patients with Dry Eye Syndrome due to LPR.
