BackgroundPrimary progressive multiple sclerosis (PPMS) is an infrequent clinical form of multiple sclerosis (MS). Scarce information is available about PPMS in Latin America. The aim of this work is to describe the clinical and demographic characteristics of PPMS patients in Argentina.Material and methodsRelevarEM is a longitudinal, strictly observational registry in Argentina. Clinical and epidemiological data from PPMS patients were described.ResultsThere were 144 cases of PPMS. They represented 7% of MS patients. The mean age was 44.1 years. The female:male ratio was 1.08. The mean Expanded Disability Status Scale (EDSS) score was 5.5 and the mean disease evolution time was 10.6 years. Oligoclonal bands were found in 72.9%. At the time of diagnosis, magnetic resonance imaging showed spinal cord lesions in 82.6% and contrast-enhancing brain lesions in 18.1% of patients. Almost one third of patients were treated with a disease-modifying drug, and ocrelizumab was the most frequently used (55.8%).ConclusionsPPMS is an infrequent subtype of MS and its recognition is of the highest importance as it has its own evolution, treatment, and prognosis. The importance of our research resides in providing local data and contributing to a better understanding of PPMS and its treatment in Latin America.

IntroductionCladribine was approved for Multiple Sclerosis (MS) in our country in 2018. A previous study by our group showed that its use among high efficacy therapies options has been increasing along the years. Objective: to analyze the cladribine use trend across time since its approval.MethodA retrospective cohort study was performed. People with MS (pwMS) treated with cladribine were included. Two periods were defined: P1 = 2018 – 2020 and P2 = 2021 – 2023. A comparative analysis was carry out between P1 and P2 to assess the trend of use, clinical/demographic characteristics, and effectiveness.ResultsOne hundred ninety- seven people with MS (pwMS) were included, mean EDSS: 2.2 ± 3.08, 72.6% female, mean age: 35.2 ± 9 years, mean disease duration: 6.6 ± 5.6 years, mean time lapse under cladribine: 26.1 ± 12.4 months. Regarding patient profile, we found significant differences between P1 and P2 in the MS evolution (p = 0.001) and EDSS ( p = 0.018) prior to initiation of cladribine. In the individualized analysis by year, we found a decrease in relapse number in the year prior to starting cladribine (p = 0.02). A higher proportion of No Evidence of Disease Activity (NEDA) was found in patients treated at P2 compared to those treated at P1 (p < 0.001).ConclusionAn earlier use of cladribine achieved a significant increase in reaching NEDA. This learning curve in the use of cladribine allows a better identification of the candidate patient and influences the treatment effectiveness.

Background The purpose of this study was to assess family planning (FP) among women with multiple sclerosis (WwMS). Methods We invited 604 WwMS to answer a survey focused on FP: a) Temporal relationship between pregnancy and the diagnosis of multiple sclerosis; b) History of FP; c) Childbearing desire; d) Information on family planning. Comparisons between pregnancy and not pregnancy after MS, as well as, planned and unplanned pregnancy were analyzed. Multivariate and univariate analyses were used to assess the impact of independent variables and FP Result 428 (71.7%) WwMS completed the survey. A 19.1% got pregnant after MS diagnosis and we evaluated FP in the last pregnancy, 56.1% patients had a planned pregnancy. Professional addressing FP (OR = 0.27, 95%-CI 0.08-0.92, p = 0.03) and non-injection drug treatment before pregnancy (OR = 2.88, 95%-CI 1.01-8.21, p = 0.047) were independent predictors of unplanned pregnancy in our multivariate model. Among WwMS ≤ 40 years, 48.7% had future childbearing desire. Young age (p < 0.001), PDDS <3 (p = 0.018), disease duration <5 years (p = 0.02), not childbearing before MS diagnosis (p < 0.001) and neurologist addressing family planning (p = 0.01) were significantly associated with childbearing desire. Conclusions This research highlights that pregnancy remains an important concern among WwMS.

Background: Perinatal anxiety and depression are common complications during pregnancy. The purpose of this study was to examine the item characteristics, reliability, validity, and factorial structure of the four-item Patient Health Questionnaire-4 (PHQ-4) and to determine the associations between scale scores and sociodemographic factors in a sample of pregnant women from Spain. Method: A total of 845 pregnant women were recruited from two public hospitals in Spain between 2014 and 2016. Participants completed a self-report questionnaire that included Patient Health Questionnaire-4, including the two-item Patient Health Questionnaire and the two-item Generalized Anxiety Disorder Screener. Results: Exploratory and confirmatory factor analysis and scale inter-correlations between the PHQ-4 and PHQ-9 revealed that the PHQ-4 has a bivariate structure and adequately assesses the dimensions of antenatal anxiety and depression. Conclusion: The PHQ-4 is a reliable and valid instrument to screen for depression and anxiety during pregnancy. The PHQ-4 is an ultra-brief measure that can be used to screen for antenatal depression and anxiety to prevent the negative consequences associated with these mental health conditions among mothers and infants.

Introducción: La maternidad es un momento en la vida de las mujeres en el que se necesita especialmente el apoyo del entorno social para mitigar las demandas que requieren el periodo de gestación y el posparto inmediato. Método: En este estudio multicéntrico, la muestra incluye 1524 mujeres embarazadas reclutadas del área obstétrica de dos hospitales españoles de tercer nivel asistencial. Se comparan las respuestas de las mujeres que dicen presentar ideación suicida con aquellas que informan no presentarla, analizando sus respuestas al ítem 9 del Patient Health Questionnaire (PHQ-9) y se comparan las diferencias en las distintas dimensiones del PHQ-9 (cognitivo-afectiva, somática y puerperal). Se analiza qué componentes del apoyo social percibido funcionaban como factores predictores de la ideación suicida prenatal, mediante el análisis de sus respuestas en el Postpartum Depression Predictors Inventory (PDPI-R). Resultados: Las mujeres con ideación suicida tienen mayor carga cognitiva-afectiva, somática y puerperal, frente a las que no presentan ideación suicida. La falta de apoyo emocional percibido de la pareja o las amistades y la falta de apoyo práctico percibido de la familia son factores que predicen la ideación suicida. Discusión: Es importante proporcionar a las mujeres con apoyo social efectivo para prevenir la ideación suicida.
