RESUMO
INTRODUCTION: The identification, diagnosis, follow-up, and treatment of patients with secondary progressive multiple sclerosis (SPMS) show significant differences between health care professionals in Argentina. AIM: To provide consensus recommendations on the management of patients with SPMS in Argentina to optimize patient care. DEVELOPMENT: A panel of expert neurologists from Argentina dedicated to the diagnosis and care of multiple sclerosis patients gathered during 2019 and 2020 to carry out a consensus recommendation on the diagnosis and treatment of SPMS patients in Argentina. To achieve consensus, the methodology of 'formal consensus-RAND/UCLA method' was used. Recommendations were established based on published evidence and the expert opinion. Recommendations focused on how to define SPMS and how to follow SPMS patients. CONCLUSION: The recommendations of this consensus guidelines attempt to optimize the care of SPMS patients in Argentina.

Existen diferencias significativas en el diagnóstico, la identificación y el seguimiento de pacientes con esclerosis múltiple secundaria progresiva (EMSP) entre los profesionales de la salud a cargo de su tratamiento. Objetivo. Proveer recomendaciones sobre el tratamiento de los pacientes con EMSP en Argentina con el fin de optimizar su cuidado. Desarrollo. Un grupo de neurólogos expertos en esclerosis múltiple de Argentina elaboró un consenso para el tratamiento de pacientes con EMSP en la región mediante metodología de ronda de encuestas a distancia y reuniones presenciales. Se establecieron 33 recomendaciones basadas en la evidencia publicada y en el criterio de los expertos que participaron. Las recomendaciones se enfocaron en el diagnóstico y el seguimiento de los pacientes con EMSP. Conclusión. Las recomendaciones establecidas en el presente consenso permitirían optimizar el cuidado y el seguimiento de los pacientes con EMSP en Argentina.

Several studies in multiple sclerosis (MS) suggest a trend of increasing disease frequency in women during the last decades. A direct comparison of gender ratio trends among MS populations from Argentina remains to be carried out. The objective of the study was to compare gender ratio trends, over a 50-year span in MS populations from Argentina. METHODS: multicenter study that included patients from 14 MS Centers of Argentina. Patients with definite MS with birth years ranging from 1940 to 1989 were included. Gender ratios were calculated by five decades based on year of birth and were adjusted for the F/M born-alive ratio derived from the Argentinean national registry of births. The F/M ratios were calculated using a multivariate logistic regression per five decades by the year of birth approach. Analyses were performed using Stata 10.1. RESULTS: 1069 patients were included. Gender ratios showed a significant increase from the first to the last decade in the whole MS sample (from 1.8 to 2.7; p value for trend=0.023). The Gender ratio did not show differences considering MS subtype. CONCLUSION: our study showed a modest increase of the F/M ratio (from 1.8 to 2.7) over time among patients affected by MS in Argentina.

UNLABELLED: The present study was carried out to assess if there is an anticipation of age at onset in younger generations of familial multiple sclerosis (FMS) vs. sporadic MS (SMS) in Argentina. METHODS: multicenter study that included patients from 14 MS Centers of Argentina. Patients were considered as FMS if they had in their family at least one relative of first or second degree diagnosed with MS; otherwise, patients were considered to have SMS. We compared the age at onset between familial and sporadic cases as well as the age at onset between relatives from different generations in FMS vs. SMS. RESULTS: 1333 patients were included, 97 of them were FMS (7.3%). A lower age at onset in the younger generations of FMS cases was found compared with older generations of FMS as well as. SMS cases (24.1±3.7 years vs. 30.3±5.7 years, and 32.4±9.4 respectively; p<0.001). No differences were observed between older generations of FMS vs. SMS cases (p=0.12). CONCLUSION: we observed an anticipation of age at onset of MS in younger generations of patients with FMS vs. older generations of FMS and SMS.

BACKGROUND: The influence of pregnancy on Multiple Sclerosis (MS) has been extensively studied but such influence on Latin American women with MS has not been characterized. Our objective was to describe the course of pregnancy and birth outcome in Argentinean MS patients and the evolution of MS during pregnancy and after delivery. METHOD: We used a retrospective design in eight MS centers in Argentina and administered a survey to women with definite MS (Mc Donald) with pregnancies during or after MS onset. We contacted 355 women of which 81 met inclusion criteria. We recorded 141 pregnancies. RESULTS: Involuntary abortion was observed in 16% of pregnancies (95% CI = 10-23). Thirty five women received immunomodulatory therapy (IMT) before 42 pregnancies. Twenty three (55%) out of 42 pregnancies were exposed to IMT. The mean time of IMT discontinuation before conception in 19 (45.2%) pregnancies without exposure, was 104 days (95% CI = 61.0-147.0). There were 103 deliveries: 79% full term. Birth defects were detected in 19% of pregnancies exposed to IMT (95% CI = 4-46) and in 2% of non-exposed (95% CI = 0.3-8.0). The mean relapse rate was: pre-pregnancy year: 0.22 (95% CI = 0.12-0.32); pregnancy: 0.31 in 1st (95% CI = 0.10-0.52), 0.19 (95% CI = 0.03-0.36) in 2nd, and 0.04 in 3rd trimester (95% CI = -0.04-0.12); 1st trimester post delivery: 0.82 (95% CI = 0.42-1.22). CONCLUSION: We observed a higher rate of birth defects among infants exposed to immunomodulators in utero than those not exposed. The reduction in MS relapses during 2nd and 3rd trimester of pregnancy and its increase during postpartum is consistent with previous reports.

Switching treatment may be beneficial in patients with relapsing-remitting multiple sclerosis (RRMS) who respond inadequately to first-line immunomodulatory therapy. The objective of this study was to evaluate clinical outcomes after switching treatment in such patients. This prospective longitudinal observational study included 114 patients with RRMS who failed first-line monotherapy and were switched treatments after 3 years. Every 3 months, patients underwent a full neurological examination. Outcome was compared between the 3-year Before Switch and After Switch treatment periods. The primary outcome measure was the annualized relapse rate; secondary outcome measures were the proportion of relapse-free patients and the median change in Expanded Disability Status Scale (EDSS). Patients were switched either from low-dose to high-dose interferon-beta (IFNbeta; n = 31), from IFNbeta to glatiramer acetate (GA; n = 52) or mitoxantrone (n = 13), or from GA to IFNbeta (n = 16). In 3 years after switching, annualized relapse rates fell by 57-78% according to the group. The proportion of relapse-free patients varied from 56% to 81%. Least improved was observed in patients switching between INFbeta preparations. Median EDSS scores remained stable in all groups except the GA to IFNbeta switchers. In conclusion, patients who fail first-line immunomodulatory therapy generally benefit from switching to another class of immunomodulatory therapy.
