[Controlled supply of tocilizumab during the COVID-19 pandemic and its influence on the treatment of rheumatological patients.] / Suministro controlado de tocilizumab durante la pandemia de COVID-19 e influencia sobre el tratamiento de pacientes reumatológicos.

OBJECTIVE: Intravenous (IV) tocilizumab has been used to stop the inflammatory phase of SARS-CoV-2 infection. To preserve the largest number of IV units for this use, the Spanish Agency for Medicines and Health Products (AEMPS) carried out a controlled supply of it and recommended the change to a subcutaneous presentation (SC) of tocilizumab or sarilumab in all those patients in IV tocilizumab treatment for rheumatologic indications. The objective of this study was to evaluate the change from IV tocilizumab to SC presentation due to its controlled supply during the COVID-19 pandemic. METHODS: Retrospective observational study of adult patients (>18 years old) under treatment with IV tocilizumab follow-up by the Rheumatology Service of the Hospital 12 de Octubre. The follow-up period was 3 months (March 2020-June 2020) and 39 patients were included in the study. Variables related to the patients and their treatment were collected. A descriptive analysis of the data was carried out. RESULTS: In 69.23% (n=27) of the patients, treatment was changed to SC tocilizumab (n=23) or sarilumab (n=4). 44% of patients (n=12) switched back to their original IV tocilizumab treatment. The reasons for stopping treatment with SC tocilizumab were: drug intolerance (n=4), disease worsening (n=4), and patient preference (n=1). Regarding sarilumab, the reasons were drug intolerance (n=2) and patient preference (n=1). CONCLUSIONS: Almost half of the patients had to return to the original treatment. The main reason was intolerance to the new treatment, followed by ineffectiveness and patient preferences.

OBJETIVO: El tocilizumab intravenoso (IV) ha sido empleado para frenar la fase inflamatoria de la infección por SARS-CoV-2. Para reservar el mayor número de unidades IV para este uso, la Agencia Española de Medicamentos y Productos Sanitarios (AEMPS) realizó una distribución controlada del mismo y recomendó el cambio a una presentación subcutánea (SC), fuera tocilizumab o sarilumab, en todos aquellos pacientes en tratamiento con tocilizumab IV para indicaciones reumatológicas. El objetivo de este trabajo fue evaluar el cambio de tocilizumab IV a una presentación SC debido a su suministro controlado durante la pandemia de COVID-19. METODOS: Se realizó un estudio observacional retrospectivo de pacientes adultos (mayores de 18 años) en tratamiento con tocilizumab IV en seguimiento por el Servicio de Reumatología del Hospital 12 de octubre (Madrid). El periodo de seguimiento fue de tres meses (marzo 2020-junio 2020) y se incluyeron 39 pacientes en el estudio. Se recogieron variables relacionadas con el paciente y su tratamiento. Se realizó un análisis descriptivo de los datos. RESULTADOS: En el 69,23% (n=27) de los pacientes se cambió el tratamiento a tocilizumab SC (n=23) o sarilumab (n=4). El 44% (n=12) de los pacientes volvieron a cambiar a su tratamiento original con tocilizumab IV. Los motivos de interrupción de tratamiento con tocilizumab SC fueron: intolerancia al fármaco (n=4), empeoramiento de la enfermedad (n=4) y preferencia del paciente (n=1). Respecto al sarilumab, los motivos fueron intolerancia al fármaco (n=2) y preferencia del paciente (n=1). CONCLUSIONES: Casi la mitad de los pacientes tuvieron que volver al tratamiento original. El principal motivo fue intolerancia al nuevo tratamiento, seguido de ineficacia y preferencias del paciente.

The Weight of IgA Anti-ß2glycoprotein I in the Antiphospholipid Syndrome Pathogenesis: Closing the Gap of Seronegative Antiphospholipid Syndrome.

The specific value of IgA Anti-ß2glycoprotein I antibodies (aB2GP1) in the diagnosis and management of antiphospholipid syndrome (APS) is still controversial and a matter of active debate. The relevance of the IgA aB2GP1 isotype in the pathophysiology of APS has been increasingly studied in the last years. There is well know that subjects with multiple positive APS tests are at increased risk of thrombosis and/or miscarriage. However, these antibodies are not included in the 2006 APS classification criteria. Since 2010 the task force of the Galveston International Congress on APS recommends testing IgA aB2GP1 isotype in patients with APS clinical criteria in the absence of criteria antibodies. In this review, we summarize the molecular and clinical "state of the art" of the IgA aB2GP in the context of APS. We also discuss some of the characteristics that may help to evaluate the real value of the IgA aB2GP1 determination in basic research and clinical practice. The scientific community should be aware of the importance of clarifying the role of IgA aB2GP1 in the APS diagnosis.
