Adaptación cultural al español del cuestionario Early Arthritis for Psoriatic Patients / Spanish Cultural Adaptation of the Questionnaire Early Arthritis for Psoriatic Patients

INTRODUCCIÓN Y OBJETIVOS: El cuestionario Early Arthritis for Psoriatic patients (EARP) es una herramienta de screening para artritis psoriásica con buenas propiedades de medición en su versión original en italiano que no ha sido todavía adaptado culturalmente al español. Este artículo expone la adaptación para población española como paso previo a su validación. MATERIAL Y MÉTODO: Aplicación de la metodología recomendada por la International Society for Pharmacoeconomics and Outcomes Research para adaptaciones culturales de medidas centradas en el paciente y que consta de las siguientes fases: preparación, traducción, reconciliación, retrotraducción y su revisión, armonización, test de comprensión y su revisión y corrección de pruebas. En la preparación se obtuvo el permiso de los autores del cuestionario original para su adaptación cultural y colaboraron durante el proceso como asesores. RESULTADOS: La traducción del cuestionario original al español la realizaron traductores nativos que realizaron pequeñas modificaciones aceptadas por los autores de la versión original. Se realizó la retrotraducción al italiano, obteniendo una versión equivalente al EARP original. La versión española después de la retrotraducción se aplicó en el test de comprensión a 35 pacientes. Todos ellos contestaron a todos los ítems sin hacer aportaciones adicionales. CONCLUSIÓN: La adaptación cultural del cuestionario EARP para población española constituye la primera etapa para su posterior uso en práctica clínica habitual. La aplicación de una metodología estandarizada garantiza la equivalencia entre el EARP en español y el original. En una segunda etapa se realizará la validación en población española

INTRODUCTION AND OBJECTIVES: The Early Arthritis for Psoriatic patients (EARP) questionnaire is a screening tool for psoriatic arthritis. The original Italian version has good measurement properties but the EARP required translation and adaptation for use in Spain. This article describes the cultural adaptation process as a step prior to validation. MATERIAL AND METHODS: We used the principles of good practice for the cross-cultural adaptation of patient-reported outcomes measurement established by the International Society Pharmacoeconomics and Outcome Research. The steps in this process were preparation, forward translation, reconciliation, back-translation and review, harmonization, cognitive debriefing and review, and proofreading. During preparation the developers of the original questionnaire were asked for their permission to adapt the EARP for use in Spain and to act as consultants during the process. RESULTS: The original questionnaire was translated into Spanish by native Spanish translators, who made slight changes that were approved by the questionnaire's developers. The Spanish version was then back-translated into Italian; that version was reviewed to confirm equivalence with the original Italian text. The reconciled Spanish EARP was then tested for comprehensibility and interpretation in a group of 35 patients. All the patients answered all items without making additional comments. CONCLUSION: This cultural adaptation of the EARP questionnaire for Spanish populations is the first step towards its later use in routine clinical practice. The application of a cross-cultural adaptation method ensured equivalence between the original and Spanish versions of the EARP. The Spanish questionnaire will be validated in a second stage

Clinical, serologic and instrumental data of ten patients affected by sclerodermatous chronic graft versus host disease: similarities and differences in respect to systemic sclerosis.

Chronic graft versus host disease (cGVHD), the most common late complication of allogeneic haematopoietic stem cell transplantation (HSCT), may present with sclerodermatous lesions resembling in some cases the cutaneous involvement of systemic sclerosis (SSc). Certain pathogenetic findings connect the two diseases. In this report we describe ten subjects affected by cGVHD who underwent the examinations routinely carried out to stage SSc patients. Demographic, clinical, serologic and instrumental data were recorded. These patients showed differences in appearance, extent and progression of the sclerodermatous lesions with greater involvement of the trunk and proximal part of the limbs than the extremities. In seven subjects ANA test was positive; scleroderma-associated autoantibodies were not detected in any of the cases. Moreover, typical organ involvement of SSc was not found. Only one patient developed Raynauds phenomenon after HSCT and only one patient demonstrated a nailfold videocapillaroscopic scleroderma pattern. Except for cutaneous involvement of cGVHD, that may resemble SSc, the clinical features of the two diseases are quite different, suggesting that the fibrotic process characterizing cGVHD and SSc has different etiologies and different initial pathobiologic events.

Safety and efficacy of etanercept in children with juvenile-onset Behcets disease.

Behcets disease (BD) is a chronic, relapsing, multi-system inflammatory disorder, clinically characterized by recurrent oral and genital ulcers, skin lesions, and uveitis. Other manifestations include arthritis, a positive pathergy test, thrombophlebitis, central nervous system disease and gastrointestinal ulcerations. The majority of affected individuals do not have life-threatening disease, although mortality can be associated with vascular-thrombotic and neurological manifestations. Currently, treatment of BD is symptomatic and empirical, and is tailored according to the severity of clinical features. In the past few years, isolated reports and case-series have been published on adult BD patients suggesting that inhibition of TNF-alpha is a promising therapeutic approach for severe ocular and various extra-ocular manifestations, including central nervous system involvement. In this study we present our promising experience with Etanercept therapy in juvenile-onset BD patients, characterized by refractory multiorgan involvement.

Lower limb enthesopathy in patients with psoriasis without clinical signs of arthropathy: a hospital-based case-control study.

BACKGROUND: Psoriasis is associated with a form of spondyloarthropathy in 10-30% of cases. A major feature of psoriatic arthritis is enthesitis. In some patients with psoriasis the presence of enthesitis could be underdiagnosed. OBJECTIVE: To investigate the presence of lower limbs entheseal abnormalities in patients with chronic plaque psoriasis without signs and symptoms of psoriatic arthritis. METHODS: Thirty patients with psoriasis and 30 controls underwent ultrasonographic evaluation of Achilles, quadriceps, patellar entheses and plantar aponeurosis. Ultrasonographic findings were scored according to the Glasgow Ultrasound Enthesitis Scoring System (GUESS). RESULTS: Mean GUESS score was significantly higher in patients with psoriasis as compared with controls: 7.9 (0.6) vs 2.9 (0.3); p<0.0001. In particular, the thickness of all tendons examined was significant higher in cases than in controls (p<0.0001), as well as the number of enthesophytes in all sites examined. In both cases and controls, the GUESS score was directly correlated with age (r = 0.22; p = 0.008), body mass index (r = 0.23, p = 0.0067) and waist circumference (r = 0.17; p = 0.02). In contrast, the GUESS score was not correlated with the duration and severity of psoriasis according to the Psoriasis Area and Severity Index (r = 0.03; p = 0.8) and body surface area involvement (r = 0.07; p = 0.6). CONCLUSIONS: Entheseal abnormalities can be documented by ultrasonography in clinically asymptomatic patients with psoriasis. These findings could be related to a subclinical entheseal psoriatic inflammation. We suggest close follow-up of patients with psoriasis with entheseal abnormalities for early diagnosis of psoriatic arthritis.

Sulfasalazine-induced immune thrombocytopenia.

Sulfasalazine is a well established disease-modifying anti-rheumatic drug commonly used in the treatment of rheumatic disorders and inflammatory bowel disease. Sulfasalazine was generally well tolerated in clinical trials, the most frequently reported adverse effects being adverse gastrointestinal effects, headache, dizziness and rash; myelosuppression can also occur. We are now reporting the first case of autoimmune thrombocytosis following sulfasalazine treatment.
