Immunotherapy, Cancer and Rheumatological Diseases: A Review of the Literature and a Series of Cases in a University Hospital. / Inmunoterapia, cáncer y enfermedades reumatológicas: revisión de la literatura y serie de casos en un hospital universitario.

The appearance in the field of oncology of therapeutic molecules in the form of monoclonal antibodies, whose objective is to stimulate the patient's own immune system to be responsible for destroying cancer cells, has revolutionized the treatment of many cancers in recent years. This type of therapy, called immunotherapy, is also characterized by presenting side effects in the form of autoimmune diseases that we are still beginning to understand. From the point of view of the immune-mediated rheumatological side effects, we can find musculoskeletal manifestations, mechanical, inflammatory or systemic autoimmune diseases. The therapeutic approach to these side effects remains uncertain due to the absence of clinical trials and validated recommendations. The multidisciplinary management is crucial to successfully treat such cases. In the following manuscript, we will describe our case reports of rheumatologic immune-related adverse events in a university hospital.

Spanish Registry of Recent-onset Psoriatic Arthritis (REAPSER study): Aims and methodology. / Registro Español de Artritis Psoriásica de Reciente Comienzo (estudio REAPSER). Objetivos y metodología.

AIMS: To describe the methodology of REAPSER (Spanish Registry of Recent-onset Psoriatic Arthritis), its strengths and limitations. The aim of this study is to identify prognostic factors for the clinical and radiographic course in a cohort of patients with psoriatic arthritis (PsA) diagnosed within 2years of symptom evolution. METHODS: Multicenter, observational and prospective study (with 2-year follow-up including annual visits). Baseline visit intended to reflect patient situation before the disease course was modified by treatments prescribed in rheumatology departments. Patients were invited to participate consecutively in one of their routine visits to the rheumatologist. 211 patients were included. Following data were collected: sociodemographic variables; employment situation; family history; personal history and comorbidities; anthropometric data; lifestyle; use of healthcare services; clinical situation at the time of PsA diagnosis; joint involvement and spinal pain; pain and overall assessment; enthesitis, dactylitis and uveitis; skin and nail involvement; functional situation and quality of life; radiographic evaluation; analytical determinations; treatment; axial and peripheral flare-ups. CONCLUSIONS: The REAPSER study includes a cohort of patients with recent-onset PsA, before the disease course was modified by disease-modifying antirheumatic drugs prescribed in rheumatology departments. Exhaustive information collected in each visit is expected to be an important data source for future analysis.

Rituximab therapy in necrotizing autoimmune myopathy associated with anti-SRP antibody: A clinical case review. / Tratamiento con rituximab para las miopatías necrosantes autoinmunes asociadas al anti-SRP: caso clínico y revisión de la evidencia.

Necrotizing autoimmune myopathy (NAM) is a rare and emerging entity of idiopathic inflammatory myopathy (IIM). They have been associated with connective tissue disorders, viral infections, malignancy, anti-signal recognition particle (SRP) and anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase protein (with or without the use of statins). Anti-SRP associated NAM has different clinical and histological characteristics that differentiate them from other IIM, resulting in a poor prognosis. Very few cases treated with rituximab have been published, with varying clinical response. Here we describe a case of anti-SRP associated NAM refractory to conventional immunosuppressants and its successful long-term management with the combination of rituximab, corticosteroids and methotrexate.

Registro Español de Artritis Psoriásica de Reciente Comienzo (estudio REAPSER). Objetivos y metodología / Spanish Registry of Recent-onset Psoriatic Arthritis (REAPSER study): aims and methodology

OBJETIVOS: Describir la metodología del Registro Español de Artritis Psoriásica de reciente comienzo de la Sociedad Española de Reumatología (REAPSER), así como sus fortalezas y limitaciones. El objetivo principal del proyecto es identificar factores pronósticos de la evolución clínica y radiográfica en una cohorte de pacientes que padecen artritis psoriásica (APs) diagnosticada con menos de 2 años de evolución. MATERIAL Y MÉTODO: Estudio observacional, prospectivo (2 años de seguimiento; periodicidad anual de las visitas), multicéntrico. La intención en la visita basal fue reflejar la situación del paciente antes de que la evolución de la enfermedad se viese modificada por los tratamientos pautados en los servicios de reumatología. Los pacientes fueron invitados a participar consecutivamente en una de sus visitas habituales al reumatólogo. El tamaño muestral finalmente alcanzado fue de 211 pacientes. Se recogen datos sociodemográficos; de situación laboral; historia familiar; antecedentes personales y comorbilidad; antropométricos; estilo de vida; uso de los servicios de salud; situación clínica al diagnóstico de APs; afectación articular y dolor espinal; dolor y valoración global de la enfermedad; entesitis, dactilitis y uveítis; afectación cutánea y ungueal; situación funcional y calidad de vida; evaluación radiográfica; determinaciones analíticas; tratamiento; brotes en esqueleto axial y periférico. CONCLUSIONES: El estudio REAPSER incluye una cohorte de pacientes con APs de inicio reciente reclutados antes de que la evolución de la enfermedad se viese modificada por la prescripción de FAME en los servicios de reumatología. Se espera que la información exhaustiva recogida en las visitas suponga una amplia fuente de datos para futuros análisis

Tratamiento con rituximab para las miopatías necrosantes autoinmunes asociadas al anti-SRP: caso clínico y revisión de la evidencia / Rituximab therapy in necrotizing autoimmune myopathy associated with anti-SRP antibody: A clinical case review

Las miopatías necrosantes autoinmunes (NAM) son unas entidades raras y emergentes de las miopatías inflamatorias idiopáticas (MII). Su presencia se ha asociado a conectivopatías, infecciones virales, neoplasias, anticuerpos frente a la partícula de reconocimiento de la señal (anti-SRP) y a anticuerpos frente a la proteína 3-hidroxi-3-metilglutaril-coenzima A reductasa (HMG-CR) (asociada al empleo o no de estatinas). Las NAM asociadas al anti-SRP presentan unas características clínicas y anatomopatológicas que las diferencian del resto de las MII, resultando en un peor pronóstico. Hasta el momento han sido muy pocos los casos publicados tratados con rituximab y con diferente respuesta clínica. Presentamos el caso de una mujer de 30 años con NAM asociada al anti-SRP refractaria a tratamiento convencional inmunosupresor y que ha sido controlada a largo plazo con la combinación de rituximab, metotrexato y corticoides

[Can the medication in patients with rheumatoidarthritis in remission be stopped?]. / ¿Se puede suspender la medicación en los pacientes con artritis reumatoide en remisión?

Rheumatoid arthritis is a chronic systemic inflammatory disease that causes significant morbidity and mortality. The combined use of methotrexate and biological agents directed against tumor necrosis factor (TNF) has achieved significant improvement in clinical, radiographic and functional parameters not seen previously and has revolutionized the therapeutic goal of achieving remission in clinical, structural and functional parameters. The next goal should be to achieve remission without the use of biological drugs and later without medication. Although there is evidence about the efficacy and safety of TNF inhibitors, there is none on remission without the use of biological agents or disease modifying drugs.

Q-fever can simulate a lupus flare.

Fever is a diagnostic challenge in the patient with lupus. Infections can mimic a lupus flare which further complicates the diagnostic approach. Moreover, immunosuppressive treatment of SLE may promote the development of infections and poor outcome. We report the case of a patient with SLE with an initial diagnosis of lupus flare, who was found to have Q fever showing an excellent response to treatment with doxycycline.

Inmunoterapia, cáncer y enfermedades reumatológicas: revisión de la literatura y serie de casos en un hospital universitario / Immunotherapy, cancer and rheumatological diseases: a review of the literature and a series of cases in a university hospital

La aparición en el campo de la oncología de moléculas terapéuticas en forma de anticuerpos monoclonales, cuyo objetivo consiste en estimular el propio sistema inmune del paciente para que sea este el encargado de destruir las células cancerígenas, ha revolucionado el tratamiento de diversos cánceres en los últimos años. Este tipo de terapia, denominada inmunoterapia, se caracteriza además por presentar efectos secundarios en forma de enfermedades autoinmunes que todavía estamos empezando a conocer. Desde el punto de vista de los efectos secundarios inmunomediados reumatológicos, podemos encontrar manifestaciones musculoesqueléticas mecánicas, inflamatorias o enfermedad autoinmune sistémica. El manejo terapéutico de estos efectos secundarios se mantiene variable debido a la ausencia de ensayos clínicos y de recomendaciones validadas, siendo el manejo multidisciplinar fundamental para tratar con éxito dichos casos. En este artículo presentamos nuestra serie de casos clínicos de pacientes en tratamiento con inmunoterapia y efectos secundarios inmunomediados reumatológicos en un hospital universitario

¿Se puede suspender la medicación en los pacientes con artritis reumatoide en remisión? / Can the medication in patients with rheumatoidarthritis in remission be stopped?

La artritis reumatoide es una enfermedad inflamatoria crónica sistémica que ocasiona una significativa morbilidad y mortalidad. El uso combinado de metotrexato y agentes biológicos dirigidos contra el factor de necrosis tumoral (TNF) ha logrado mejorías significativas en parámetros clínicos, radiográficos y funcionales que no se habían visto previamente y que han revolucionado el objetivo terapéutico de conseguir la remisión en parámetros clínicos, estructurales y funcionales. El próximo objetivo debería ser alcanzar la remisión sin el uso de fármacos biológicos y posteriormente sin medicación. Aunque hay evidencia acerca de la eficacia y la seguridad de los inhibidores del TNF, no la hay acerca de remisión sin el empleo de agentes biológicos ni fármacos modificadores de la enfermedad (AU)

La fiebre Q puede simular un brote lúpico / Q-fever can simulate a lupus flare

La fiebre constituye un reto diagnóstico en el paciente lúpico. Algunas infecciones pueden imitar un brote de la enfermedad, lo que complica aún más la orientación diagnóstica. Por otra parte, el tratamiento inmunodepresor del lupus eritematoso sistémico (LES) puede favorecer la aparición de infecciones y su mala evolución. Presentamos el caso de una paciente con LES en tratamiento con antipalúdicos y dosis bajas de esteroides, cuyo diagnóstico inicial fue de brote lúpico y que resultó tener fiebre Q, presentando una respuesta excelente al tratamiento con doxiciclina (AU)
