Epiescleritis y edema periorbitario secundario a síndrome VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) / Episcleritis and periorbital edema secondary to VEXAS syndrome

El síndrome vacuolas, E1 enzyme, X-linked, autoinflammatory, somatic (VEXAS) es una nueva entidad autoinflamatoria descrita recientemente, producida por una mutación del gen UBA-1. Entre los síntomas más frecuentes están la fiebre, las citopenias, la policondritis, los infiltrados pulmonares y hasta en un 40% afectación ocular en forma de edema periorbitario, uveítis, epiescleritis, escleritis y vasculitis retiniana. Los pacientes responden a altas dosis de corticoterapia, sin embargo muchos terminan siendo refractarios a las mismas y a los inmunosupresores clásicos. Se describe el caso de un paciente varón de 77 años con afectación ocular en forma de epiescleritis y edema periorbitario que posteriormente fue diagnosticado de síndrome VEXAS. El paciente, tras fracasar al tratamiento con inmunosupresores, en la actualidad está en tratamiento con esteroides orales y tocilizumab. Los especialistas en oftalmología deben estar al corriente de la afectación oftalmológica de las enfermedades autoinflamatorias, y en especial de esta nueva entidad descrita, como es el síndrome VEXAS (AU)

VEXAS (vacuoles, E1 enzyme, X-linked, autoinflammatory, somatic) syndrome is a newly described autoinflammatory entity caused by a UBA-1 gene mutation. Among the most frequent symptoms it produces fever, cytopenias, polychondritis, pulmonary infiltrates and up to 40% ocular involvement such as periorbital edema, uveitis, episcleritis, scleritis and retinal vasculitis. Patients respond to high doses of corticosteroids, however, many end up being refractory to them and to the classic immunosuppressants. We described the case of a 77-year-old male patient with ocular involvement in the form of episcleritis and periorbital edema who was later diagnosed with VEXAS syndrome. The patient, after failing treatment with immunosuppressants, is currently receiving treatment with oral steroids and tocilizumab. Ophthalmologist must be aware of the ophthalmological affectation of autoinflammatory diseases and especially of this new entity described as the VEXAS syndrome (AU)

Resultados del programa de cribado de enfermedad de Fabry en pacientes con córnea verticillata en el Hospital Universitario de Navarra / Results of the screening program for Fabry disease in patients with cornea verticillata at the University Hospital of Navarre

Introducción La cornea verticillata (CV) o queratopatía vortex se caracteriza por la presencia de depósitos en forma de espiral en el epitelio corneal. Las causas más frecuentes son los fármacos antipalúdicos y la amiodarona, y dentro de las causas sistémicas la enfermedad de Fabry (EF). Material y métodos Se realiza un estudio descriptivo prospectivo multidisciplinar en un centro de tercer nivel y de referencia en la Comunidad Foral de Navarra, tras la implementación de un programa de despistaje de la EF en los pacientes atendidos en consultas del servicio de oftalmología que eran diagnosticados de CV y posteriormente fueron remitidos a la consulta de enfermedades minoritarias del servicio de Medicina Interna del Hospital Universitario de Navarra para la realización del estudio de la EF. Resultados Dos mujeres y 4 varones, con una edad media de 76,8 años, se diagnosticaron de CV, de un total de 17.280 pacientes valorados en consultas externas por 3 especialistas de oftalmología durante el periodo de abril de 2018 a abril de 2020. Una paciente falleció antes de realizar el estudio de despistaje y en ningún paciente se diagnosticó la EF. Conclusiones A pesar de que el programa de despistaje de la EF en pacientes con CV en el Hospital Universitario de Navarra no confirmó ningún caso con EF, los especialistas en oftalmología deben tener en cuenta el posible diagnóstico de la EF en aquellos pacientes con CV en sus consultas rutinarias (AU)

Introduction Cornea verticillata (CV) or vortex keratopathy is characterized by the presence of spiral-shaped deposits in the corneal epithelium. The most frequent causes are antimalarial drugs and amiodarone and, among systemic causes, Fabry disease (FD). Material and methods A multidisciplinary, prospective, descriptive study was conducted in a tertiary reference center in Spain's Autonomous Community of Navarre after the implementation of a FD screening program for patients attended to in the Ophthalmology Department. The study analyzed those diagnosed with CV, who were subsequently referred to the rare disease clinic of the University Hospital of Navarre's Internal Medicine Department for an FD study. Results Two women and four men with a mean age of 76.8 years were diagnosed with CV out of a total of 17,280 patients evaluated in outpatient consultations by three ophthalmology specialists during the period from April 2018 to April 2020. One patient died before performing the screening study and no patients were diagnosed with FD. Conclusions Despite the fact that the University Hospital of Navarre's FD screening program for patients with CV did not confirm any cases of FD, ophthalmology specialists should consider the possible diagnosis of FD in patients with CV in their routine consultations (AU)

Multidisciplinary care and units for uveitis in the internal medicine departments in Spain: Survey of the Systemic Autoimmune Diseases Group.

OBJECTIVE: To identify the multidisciplinary uveitis units in which internal medicine departments participate in collaboration with ophthalmology departments in Spain. MATERIAL AND METHODS: We conducted a multicentre, observational cross-sectional study that collected information using a structured survey sent by email to 1015 partners of the Systemic Autoimmune Diseases Workgroup of the Spanish Society of Internal Medicine (GEAS-SEMI) from the 1st to the 31st of March 2017. RESULTS: We identified a total of 21 support units/consultations for the ophthalmology departments. Seventeen (81%) of the units were specific internal medicine-ophthalmology consultations, and 5 (24%) units had been created in the past 5 years. A median of 460 patients were assessed per unit by the end of the year. CONCLUSIONS: This study shows, for the first time in Spain, the important and close collaboration between ophthalmologists and internists, especially in highly specialized national reference institutions.

Síndrome de la transiluminación iridiana aguda bilateral. A propósito de un caso clínico / Bilateral acute iris transillumination syndrome. A case report

OBJETIVO: Presentar el caso clínico de una paciente con el síndrome de la transiluminación iridiana aguda bilateral (BAIT). MÉTODOS: El síndrome de BAIT es una nueva entidad clínica caracterizada por una transiluminación iridiana, dispersión de pigmento en la cámara anterior y una pupila en midriasis media que no responde o es poco sensible a la luz debido a una parálisis del esfínter. Los pacientes con BAIT suelen presentar dolor ocular agudo, fotofobia y ojo rojo. DISCUSIÓN: Presentamos el caso clínico de una mujer de 53 años que, tras ser tratada de una infección del tracto respiratorio superior con moxifloxacino, desarrolló un síndrome de BAIT, diagnosticado en primera instancia de uveítis anterior aguda. CONCLUSIÓN: Este es, hasta donde se conoce, el primer caso reportado en Navarra, aunque es necesaria mayor casuística para establecer patrones claros acerca de esta enfermedad

OBJECTIVE: To present a case report of a patient with a bilateral acute iris transillumination syndrome (BAIT). METHODS: BAIT syndrome is a new clinical condition characterised by severe transillumination of the iris, acute onset of pigment dispersion in the anterior chamber, and a medial mydriatic pupil that is unresponsive or poorly responsive to light, due to a sphincter paralysis. Patients with BAIT generally present with acute ocular pain, photophobia, and red eyes. DISCUSSION: The case is presented of a 53 year-old woman, who, after being treated with moxifloxacin for an upper respiratory tract infection, developed a BAIT syndrome, which was initially diagnosed as acute anterior uveitis. CONCLUSION: As far as is known this is the first case reported in Navarra, but more case reports are needed to establish clear patterns about this condition

[Extrapulmonary tuberculosis]. / Tuberculosis extrapulmonar.

In spite of the lung being the target organ par excellence of tuberculosis, any other organ and system can be affected. In this article we review the forms of extrapulmonary tuberculosis, with the exception of the pleural form that requires the use of good diagnostic skills. From the dreaded tuberculous meningitis, by way of the insidious affectation of the spondylodiscitis, the so-called ganglionary affectation , the genitourinary affectation, pericarditis, and ending with less frequent forms such as ocular and cutaneous tuberculosis. In each section we will indicate what is most characteristic with the aim of providing a diagnostic and therapeutic orientation.

[Silicosis]. / Silicosis.

Silicosis, which acquired great significance during the period of increase in mining and construction, continues to be a pathology with a high morbidity and mortality within pneumoconiosis. Exposure to silica produces pathological, clinical and radiological alterations that together with compatible personal antecedents suggests its diagnosis in a simple way. The associated complications as well as its differential diagnosis from other types of pneumopathy mean that a review of this entity is needed.

[Hypersensitivity Pneumonitis (extrinsic allergic alveolitis)]. / Neumonitis por hipersensibilidad (alveolitis alérgica extrínseca).

Farmer's lung was first described in 1932. We can define hypersensitivity pneumonitis as a pulmonary and systemic disease that is accompanied by dyspnoea and coughing; it is caused by an immunological type of inflammation of the alveolar walls and the terminal airways and it is secondary to the repeated inhalation of a variety of antigens by a susceptible host. It can be said that it is an underdiagnosed disease and only a high degree of clinical manifestations and a detailed history of exposure can lead to an early diagnosis and satisfactory treatment. A combination among clinical-radiological, functional, cytological or pathological findings leads in some cases to a diagnosis. Treatment is based on avoiding further exposure to the causal agent and in the more serious cases the administration of systemic corticoid treatment.
