Objetivos y metodología de la fase III de BIOBADASER / Objectives and methodology of BIOBADASER phase III

Objetivo: Describir los objetivos, la metodología y los resultados del primer año de la nueva versión del registro español de acontecimientos adversos de terapias biológicas y fármacos sintéticos con diana identificable en enfermedades reumáticas (BIOBADASER III). Metodología: Registro prospectivo multicéntrico de pacientes con enfermedades inflamatorias reumáticas en tratamiento con terapia biológica o fármacos sintéticos con diana identificable y atendidos en servicios de Reumatología en España. El objetivo principal de BIOBADASER Fase III es la recogida y análisis de acontecimientos adversos al que se ha añadido como objetivo secundario la evaluación de la efectividad mediante la recogida de índices de actividad. Los pacientes que entran en el registro son evaluados al menos una vez cada año y cada vez que presenten un acontecimiento adverso o se produzcan modificaciones en el tratamiento. La recogida de datos de la fase iii se inició el 17 de diciembre del 2015. Resultados: Durante el primer año han participado 35 centros. El número de pacientes incluidos en esta nueva fase en diciembre del 2016 era de 2.664. La edad media era de 53,7 años, con una mediana de duración de la enfermedad hasta el inicio de tratamiento de 8,1 años. Un 40,4% de los pacientes estaban diagnosticados de artritis reumatoide. Los acontecimientos adversos más frecuentes eran las infecciones e infestaciones. Conclusiones: La fase iii de BIOBADASER se ha puesto en marcha para responder a un entorno farmacológico cambiante con la aparición de los biosimilares y las pequeñas moléculas en el tratamiento de la patología reumática. Esta nueva etapa se adapta a los cambios normativos en la comunicación de acontecimientos adversos y amplía la información recogida incluyendo los índices de actividad

Objective: Describe the objectives, methods and results of the first year of the new version of the Spanish registry of adverse events involving biological therapies and synthetic drugs with an identifiable target in rheumatic diseases (BIOBADASER III). Methodology: Multicenter prospective registry of patients with rheumatic inflammatory diseases being treated with biological drugs or synthetic drugs with an identifiable target in rheumatology departments in Spain. The main objective of BIOBADASER Phase III is the registry and analysis of adverse events; moreover, a secondary objective was added consisting of assessing the effectiveness by means of the registry of activity indexes. Patients in the registry are evaluated at least once every year and whenever they experience an adverse event or a change in treatment. The collection of data for phase iii began on 17 December 2015. Results: During the first year, 35 centers participated. The number of patients included in this new phase in December 2016 was 2,664. The mean age was 53.7 years and the median duration of treatment was 8.1 years. In all, 40.4% of the patients were diagnosed with rheumatoid arthritis. The most frequent adverse events were infections and infestations. Conclusions: BIOBADASER Phase III has been launched to adapt to a changing pharmacological environment, with the introduction of biosimilars and small molecules in the treatment of rheumatic diseases. This new stage is adapted to the changes in the reporting of adverse events and now includes information related to activity scores

Factors associated with long-term retention of treatment with golimumab in a real-world setting: an analysis of the Spanish BIOBADASER registry.

The retention rate of a biological drug (percentage of patients remaining on treatment over time) provides an index of a drug's overall effectiveness. The golimumab retention rate as first-line biological therapy was high in clinical trial extensions lasting 5 years. Real-world studies also indicate good retention rates but have been of shorter duration. The probability of retention with golimumab treatment was assessed, as any line of anti-tumor necrosis factor-alpha therapy, for up to 5 years in patients with rheumatoid arthritis (RA), axial spondyloarthritis (SpA) or psoriatic arthritis (PsA), associated factors were analyzed. A retrospective database analysis of the Spanish registry of patients with rheumatic disorders receiving biological drugs (BIOBADASER) was performed. Among 353 patients, 29.8% had RA, 41.6% SpA and 28.6% PsA. Golimumab was the first biological drug in 40.1% of patients, second in 30.1% and third/later in 29.8%. The overall probability of retention of golimumab at years 1, 2, 3, 4 and 5 was 85.9% (95% confidence interval 81.4-89.5%), 73.7% (67.1-79.1%), 68.5% (60.5-75.1%), 60.6% (50.2-69.5%) and 57.1% (44.9-67.5%), respectively. Retention was similar across indications (p = 0.070) but was greater when golimumab was used as the first biological agent compared with later therapy lines (p < 0.001). Factors associated with higher retention of golimumab treatment (Cox regression) were use as a first-line biological and concomitant methotrexate treatment; corticosteroid need was associated with lower retention. The long-term probability of golimumab retention was high in this real-world study of patients with rheumatic diseases, especially when used as the first biological drug.

The number of circulating monocytes as biomarkers of the clinical response to methotrexate in untreated patients with rheumatoid arthritis.

BACKGROUND: The aim of this work was to analyze the number and distribution of circulating monocytes, and of their CD14(+high)CD16(-), CD14(+high)CD16(+) and CD14(+low)CD16(+) subset cells, in treatment-naive patients with rheumatoid arthritis (RA), and to determine their value in predicting the clinical response to methotrexate (MTX) treatment. METHODS: This prospective work investigated the number of circulating monocytes, and the numbers of CD14(+high)CD16(-), CD14(+high)CD16(+) and CD14(+low)CD16(+) subset cells, in 52 untreated patients with RA before MTX treatment, and at 3 and 6 months into treatment, using flow cytometry. RESULTS: The absolute number of circulating monocytes, and the numbers of CD14(+high)CD16(-), CD14(+high)CD16(+) and CD14(+low)CD16(+) subset cells, were significantly higher in MTX non-responders than in responders and healthy controls before starting and throughout treatment. Responders showed normal numbers of monocytes, and of their subset cells, over the study period. The pre-treatment absolute number of circulating monocytes, and the numbers of CD14(+high)CD16(-) and CD14(+high)CD16(+) subset cells, were found to be predictive of the clinical response to MTX, with a sensitivity and specificity of >70% and >88%, respectively. CONCLUSIONS: Treatment-naive patients with RA showed an anomalous distribution of circulating monocyte subsets, and an anomalous number of cells in each subset. A higher pre-treatment number of circulating monocytes, and higher numbers of CD14(+high)CD16(-) and CD14(+high)CD16(+) subset cells, predict a reduced clinical response to MTX in untreated patients with RA.

Sarcoma de Kaposi en paciente con síndrome antisintetasa en tratamiento corticoideo / Kaposi's sarcoma in a steroid-treated antisynthetase antibody syndrome patient

El sarcoma de Kaposi (SK) es un tumor vascular maligno conocido fundamentalmente por ser una complicación del síndrome de inmunodeficiencia adquirida (sida), pero también asociado a inmunosupresión en trasplantados renales y, menos frecuentemente, en otras enfermedades. Se presenta un caso de SK en un paciente diagnosticado de síndrome antisintetasa en tratamiento con corticoides (AU)

Kaposi's sarcoma (KS) is a malignant vascular tumor widely known as a complication of acquired immunodeficiency syndrome (AIDS) but also related to immunosuppression in renal transplants, and less frequently, to other diseases. We describe a case of KS in a patient affected by antisynthetase syndrome treated with steroids (AU)

Kaposi's sarcoma in a steroid-treated antisynthethase antibody syndrome patient.

Kaposi's sarcoma (KS) is a malignant vascular tumor widely known as a complication of acquired immunodeficiency syndrome (AIDS) but also related to immunosupression in renal transplants, and less frequently, to other diseases. We describe a case of KS in a patient affected by anti-synthetase syndrome treated with steroids.

Both baseline clinical factors and genetic polymorphisms influence the development of severe functional status in ankylosing spondylitis.

Functional severity in ankylosing spondylitis (AS) patients is variable and difficult to predict early. The aim of our study was to assess whether a combination of baseline clinical factors and genetic markers may predict the development of severe functional status in AS. We performed a cross-sectional association study on AS patients included in the Spanish National Registry of Spondyloarthropathies--REGISPONSER. Bath Ankylosing Spondylitis Functional Index (BASFI) was standardized by adjusting for disease duration since the first symptoms (BASFI/t). We considered as severe functional status the values of BASFI/t in the top of the 60th (p60), 65th (p65), 70th (p70), and 75th (p75) percentile. We selected 384 single nucleotide polymorphisms (SNPs) distributed in 190 genes to be analyzed. The study cohort included 456 patients with mean age 50.8(± 10.5) years and with mean disease duration since first symptoms 24.7 (± 10.1) years. Older age at disease onset and neck pain at baseline showed statistical significant association with severe BASFI/t. Polymorphisms associated in the allele frequencies test with severe BASFI/t in all classifications were: rs2542151 (p60 [P = .04], p65 [P = .04], p70 [P = .001] and p75 [P = .001]) and rs2254441 (p60 [P = .004], p65 [P = .02], p70 [P = .01] and p75 [P<.001]).. Genotype association, after adjustment for covariates, found an association in three of the four patients' classifications for rs2542151 and in two of the classifications for rs2254441.Forward logistic regression did not identify any model with a good predictive power for severe functional development.In our study we identified clinical factors and 24 polymorphisms associated with development of severe functional status in AS patients. Validation of these results in other cohorts is required.

Monocyte populations as markers of response to adalimumab plus MTX in rheumatoid arthritis.

INTRODUCTION: The treatment of rheumatoid arthritis (RA) patients with anti-tumor necrosis factor alpha (TNFα) biological drugs has dramatically improved the prognosis of these patients. However, a third of the treated patients do not respond to this therapy. Thus, the search for biomarkers of clinical response to these agents is currently highly active. Our aim is to analyze the number and distribution of circulating monocytes, and of their CD14⁺highCD16⁻, CD14⁺highCD16⁺ and CD14⁺lowCD16+ subsets in methotrexate (MTX) non-responder patients with RA, and to determine their value in predicting the clinical response to adalimumab plus MTX treatment. METHODS: This prospective work investigated the number of circulating monocytes, and of their CD14⁺highCD16⁻, CD14⁺highCD16⁺ and CD14⁺lowCD16⁺ subsets, in 35 MTX non-responder patients with RA before and after three and six months of anti-TNFα treatment using multiparametric flow cytometry. The number of circulating monocytes in an age- and sex-matched healthy population was monitored as a control. RESULTS: Non-responder patients with RA show an increased number of monocytes and of their CD14⁺highCD16⁻, CD14⁺highCD16⁺ and CD14⁺lowCD16⁺ subsets after three months of adalimumab plus MTX treatment that remained significantly increased at six months. In contrast, significant normalization of the numbers of circulating monocytes was found in responders at three months of adalimumab plus MTX treatment that lasts up to six months. CX3CR1 expression is increased in monocytes in non-responders. At three months of anti-TNFα treatment the number of circulating monocytes and their subsets was associated with at least 80% sensitivity, 84% specificity and an 86% positive predictive value (PPV) in terms of discriminating between eventual early responders and non-responders. CONCLUSIONS: The absolute number of circulating monocytes and of their CD14⁺highCD16⁻, CD14⁺highCD16⁺ and CD14⁺lowCD16⁺ subsets at three months of adalimumab plus MTX treatment, have a predictive value (with high specificity and sensitivity) in terms of the clinical response after six months of anti-TNFα treatment in patients with RA.

Nephrogenic systemic fibrosis in a patient with a p-ANCA systemic vasculitis.

Nephrogenic systemic fibrosis (NSF) is a fibrosing skin condition of unknown origin. Most cases have been described in patients with acute or chronic renal failure. The cutaneous changes include firm and thickened, indurate skin plaques and papules on the extremities and trunk. Histopathology typically shows an increase in dermal fibroblast-like cells associated with mucin deposition. Previous exposition to gadolinium-based contrast agents was closely associated with its onset. We described a patient with the clinical and pathologic picture of NSF presented after an acute renal failure in the course of a perinuclear antineutrophil cytoplasmic antibodies associated systemic vasculitis.

Edema linfático y poliartritis / Lymphedema and polyarthritis

La asociación de edema linfático y poliartritis crónica se describe ocasionalmente en la bibliografía. Los mecanismos de producción del endema aún son discutidos. La obstrucción mecánica al flujo linfático y la disminución del drenaje linfático como consecuencia de tenosinovitis y linfangitis son los mecanismos más frecuentemente implicados. Describimos a 2 pacientes con edema linfático y poliartritis crónica con diferente comportamiento en la evolución y respuesta al tratamiento. (AU)
