Efecto de unas gotas a base de ácido hialurónico, Aloe vera y Centella asiática en la calidad de vida de pacientes con ojo seco / Effect of eye drops based on hyaluronic acid, Aloe vera and Centella asiatica on quality of life of patients with dry eye

Introducción: la enfermedad de ojo seco (EOS) es una patología común y un motivo de consulta frecuente en farmacia comunitaria. Esta tiene un gran impacto en la calidad de vida (QoL) de los pacientes; por ello, un tratamiento adecuado debería mejorarla. Las lágrimas artificiales constituyen la base para el manejo de la EOS y el principal tratamiento de indicación farmacéutica.Objetivo: estudiar el efecto de unas gotas oculares a base de ácido hialurónico, Centella asiática y Aloe vera en la QoL de pacientes con EOS. Paralelamente, la adherencia al tratamiento, la tolerancia y seguridad del producto, fueron evaluados.Metodología: estudio clínico posautorización, abierto, prospectivo y multicéntrico. Los pacientes recibieron el tratamiento durante 60 días. Para estudiar el efecto sobre la QoL, los pacientes cumplimentaron el cuestionario OSDI© antes de iniciar el tratamiento y a los 30 y 60 días de tratamiento. La adherencia se evaluó mediante la reconciliación de los envases y la seguridad mediante un seguimiento de los eventos adversos. Resultados: los pacientes tratados con las gotas oculares, población por intención de tratar (ITT, n=44), obtuvieron mejoras clínicamente importantes en la QoL, sintomatología y función visual, pues la puntuación OSDI© disminuyó de 32,80 (DE=23,00) (basal, EOS severo) a 12.64 (DE=15,32) (estado normal, p<0,001), y a 9.22 (DE=10,37) (estado normal, p<0,001), a los 30 y 60 días, respectivamente. Más del 70 % de los pacientes se adhirieron al tratamiento. El perfil de seguridad fue favorable. Se observaron 4 efectos adversos oculares de intensidad leve. No se plantearon problemas de seguridad. Conclusiones: Las gotas oculares objeto de estudio podrían ser una opción de tratamiento efectiva y segura para mejorar la QoL de pacientes con EOS.

Epidermal Fatty Acid-Binding Protein: A Novel Marker in the Diagnosis of Dry Eye Disease in Sjögren Syndrome.

PURPOSE: Sjögren syndrome (SS) is a chronic inflammatory autoimmune disease of the lacrimal and salivary glands. This study compared the concentrations of epidermal fatty-acid binding protein (E-FABP) in the saliva, serum, and tears of SS patients with dry eye and dry mouth, with those of healthy adults to investigate the usefulness of E-FABP as a diagnostic marker for SS. DESIGN: Prospective, observational case series. PARTICIPANTS: The subjects were 11 new patients with untreated Sjogren syndrome and 12 healthy control individuals. METHODS: The diagnosis of SS was in accordance with the Ministry of Health, Labour and Welfare (Japan) Diagnostic Criteria (1999). Saliva, serum, and tear specimens were collected during internal medicine, dental, and ophthalmological examinations. The ophthalmological tests included the Dry Eye-related Quality of life Score (DEQS), tear break-up time (BUT), vital staining with fluorescein (FS) and lissamine green (LG), and the Schirmer test-1. The E-FABP concentration in the tears, saliva, and serum was measured by enzyme-linked immunosorbent assay (ELISA). MAIN OUTCOME MEASURE: The E-FABP concentrations were compared between patients and controls. RESULTS: There were significant differences between the patient and healthy control groups in all ophthalmological test results. There were no significant differences between the groups in the E-FABP concentrations in the saliva (p = 0.1513) or the serum (p = 0.4799), but the E-FABP concentration in the tears significantly differed between groups. The E-FABP concentration in tears tended to be significantly lower in patients with SS (mean, 323.5 ± 325.6 pg/mL) than healthy control subjects (mean, 4076 pg/mL; p = 0.0136). The E-FABP concentration in tears significantly correlated with the results of dry eye parameters. CONCLUSION: The E-FABP concentration in tears appears to be related to ocular surface epithelial damage and tear stability and may be a promising novel biomarker in the diagnosis of SS.

Discrepancy between subjective symptoms, objective measures and disease activity indexes: the lesson of primary Sjögren's syndrome.

Mucosal dryness is a key clinical feature in primary Sjögren's syndrome (pSS) and its assessment relies on both objective measurement of residual secretion and subjective symptoms reported by patients. However, while the objective assessment and grading of glandular dysfunction can be easily performed, the spectrum of clinical symptoms encompassed by the terms 'dry eye' and 'dry mouth' is wide and heterogeneous. Therefore, patient reported outcomes (PROs) for dryness in pSS poorly correlate with the amount of glandular secretion. In addition, subjective dryness is not correlated with the severity of systemic disease and severely affects the patient quality of life even in presence of active extraglandular manifestations. The purpose of this review article is to provide an overview of glandular dysfunction in pSS as well as the impact of discrepancy between objective assessment, subjective symptom and extraglandular disease activity on disease management.

Autoimmune rheumatic disease associated symptoms in fibromyalgia patients and their influence on anxiety, depression and somatisation: a comparative study.

OBJECTIVES: In this study we evaluated the frequency of autoimmune rheumatic disease associated major symptoms in fibromyalgia (FM) patients, and the association between their presence and anxiety, depression and somatisation. METHODS: Two hundred and thirty-two FM, 78 systemic lupus erythematosus (SLE) patients and 70 healthy controls were included. All subjects were questioned face-to-face for the presence of autoimmune rheumatic disease-associated symptoms and antinuclear antibody (ANA) was determined. All FM patients were questioned for the severity of pain and symptoms of FM by using a visual analogue scale. In addition, all subjects were interrogated for anxiety, depression, somatic symptoms and neuropathic pain by using different validated questionnaires. RESULTS: FM patients had significantly higher frequency of photosensitivity (27.6% vs. 11.4%) and Raynaud phenomenon (22% vs. 10%) when compared to controls (p-values, 0.005 and 0.026). FM patients had significantly lower frequencies of photosensitivity, oral ulcers, xerostomia, and xerophthalmia than SLE patients (all p-values <0.001). ANA positivity was 11.8% in FM patients and 7.1% in healthy controls. ANA-positive and negative FM patients had similar frequencies of autoimmune rheumatic disease symptoms. FM patients with photosensitivity had higher anxiety (p=0.002), somatic symptoms (p=0.015) and neuropathic pain (p=0.03) scores than others. FM patients with Raynaud had higher anxiety (p=0.004), depression (p=0.001), somatic symptom (p<0.001) and neuropathic pain scores than others. CONCLUSIONS: The presence of which findings in FM seems to be associated with anxiety, depression, and somatization rather than ANA positivity and disease severity.

Keratomalacia caused by psychiatric-induced dietary restrictions.

PURPOSE: To describe the unique presentation, clinical course, management, and outcome of vitamin A deficiency-induced keratomalacia leading to bilateral corneal melts and ulcers in a patient with severe dietary restrictions because of psychiatric disease. METHODS: Review of patient's record and literature pertinent to her condition. RESULTS: A 33-year-old woman with a phobia of consuming most foods presented with bilateral corneal ulcers and melts from an unusual case of keratomalacia caused by vitamin A deficiency. The disease process progressed to bilateral perforations necessitating emergent bilateral penetrating keratoplasties. Pathologic examination confirmed classic signs of xerosis and keratomalacia. To our knowledge, our case is unique in that it is the only one in which the histopathology of the corneal lesion is described. CONCLUSIONS: Psychiatric diseases, particularly eating disorders limiting sufficient nutrient intake, can lead to severe ocular surface disease that can be both vision- and life threatening.
