INTRODUCTION: The influence of breastfeeding and it ́s duration on the course of multiple sclerosis (MS) is unclear. Here we analyzed a real-world data for breastfeeding women with MS and their disease course collected from a Czech national registry ReMuS. OBJECTIVES: To identify risk factors associated with not initiating breastfeeding after delivery, to analyze the impact of breastfeeding on the MS disease course, evaluate the assumption, that breastfeeding is not harmful in MS patients, and compare the disease course by breastfeeding status. MATERIALS AND METHODS: Using propensity score matching we compared Expanded Disability Status Scale (EDSS), confirmed disease worsening (CDW) and annual relapse rate (ARR) in breastfeeding and non-breastfeeding MS patients according to disease duration, disease modifying treatment (DMT) before pregnancy, last EDSS score before conception, age, and ARR during pregnancy. We also compared these parameters between breastfeeding patients not using a DMT and non-breastfeeding patients who resumed DMT within 3 months after delivery. EDSS, ARR, and CDW were collected at 12, 24, and 36 months after delivery. RESULTS: A total of 1681 pregnancies that ended in delivery were analyzed from 2013 through 2020. Change in ARR and EDSS values and 6-months CDW did not significantly differ between the analyzed groups. Compared with non-breastfeeding women who resumed DMT early after delivery, breastfeeding women with MS did not experience worse clinical outcomes even without initiating a DMT. DISCUSSION: Breastfeeding in Czech women with MS did not negatively affect the disease course and can be supported. Patients with MS can be treated with certain DMTs alongside breastfeeding and there is no need to stop breastfeeding, if the patient is clinically stable.

BACKGROUND: A special care of MS women planning a pregnancy is highly demanding especially in the terms of disease modifying treatment (DMD) decisions and counselling regarding periods of conception, pregnancy and postpartum period. OBJECTIVE: To provide data about impact of pregnancy, delivery or miscarriage/artificial abortion on MS disease course in Czech women with MS based on analysis of retrospective data from the Czech national registry ReMuS. METHODS: The analysis focused on women with MS with at least one record of pregnancy in the registry. Clinical data (EDSS, relapses) were collected prior to conception, during pregnancy and after delivery or miscarriage/artificial abortion. These data were analysed according to baseline characteristics of DMD treatment prior to conception and according to breastfeeding status. RESULTS: A total of 1 533 pregnancies were analysed from the period of 2013 until 31st December 2019. The occurrence of relapses and worse EDSS was significantly related to the treatment with escalation therapy prior to conception. Relapses were significantly more frequent in women who breastfed less than 3 months than in women who breastfed more than 3 months or did not breastfeed at all. Patients treated with either fingolimod or natalizumab prior to pregnancy were significantly more likely to develop relapses during pregnancy. CONCLUSION: Pregnancy and postpartum period were generally safe for Czech women with MS. Better disease outcomes were observed in those who had been treated with first line injectable DMDs prior to conception and those who either breastfed more than 3 months or did not breastfeed at all. We confirmed the assumption of rebound phenomenon of MS after discontinuation of treatment due to planned pregnancy both for fingolimod and natalizumab.

BACKGROUND: When the novel coronavirus disease 2019 (COVID-19) appeared, concerns about its course in patients with multiple sclerosis (MS) and neuromyelitis optica spectrum disorder (NMOSD) arose. This study aimed to evaluate the incidence, severity and risk factors of the more severe COVID-19 course among MS and NMOSD patients. METHODS: From March 1, 2020, to February 28, 2021, 12 MS centres, representing 70% of the Czech MS and NMOSD population, reported laboratory-confirmed COVID-19 cases via the Czech nationwide register of MS and NMOSD patients (ReMuS). The main outcome was COVID-19 severity assessed on an 8-point scale with a cut-off at 4 (radiologically confirmed pneumonia) according to the World Health Organisation´s (WHO) COVID-19 severity assessment. RESULTS: We identified 958 MS and 13 NMOSD patients, 50 MS and 4 NMOSD patients had pneumonia, 3 MS and 2 NMOSD patients died. The incidence of COVID-19 among patients with MS seems to be similar to the general Czech population. A multivariate logistic regression determined that higher body mass index (BMI [OR 1.07, 95% CI, 1.00-1.14]), older age (OR per 10 years 2.01, 95% CI, 1.41-2.91), high-dose glucocorticoid treatment during the 2 months before COVID-19 onset (OR 2.83, 95% CI, 0.10-7.48) and anti-CD20 therapy (OR 7.04, 95% CI, 3.10-15.87) were independent variables associated with pneumonia in MS patients. Increase odds of pneumonia in anti-CD20 treated MS patients compared to patients with other disease-modifying therapy (same age, sex, BMI, high-dose glucocorticoid treatment during the 2 months before COVID-19 onset, presence of pulmonary comorbidity) were confirmed by propensity score matching (OR 8.90, 95% CI, 3.04-33.24). Reports on COVID-19 infection in patients with NMOSD are scarce, however, data available up to now suggest a high risk of a more severe COVID-19 course as well as a higher mortality rate among NMOSD patients. In our cohort, 4 NMOSD patients (30.77%) had the more severe COVID-19 course and 2 patients (15.39%) died. CONCLUSION: The majority of MS patients had a mild COVID-19 course contrary to NMOSD patients, however, higher BMI and age, anti-CD20 therapy and high-dose glucocorticoid treatment during the 2 months before COVID-19 onset were associated with pneumonia. Based on this study, we have already started an early administration of anti-SARS-CoV-2 monoclonal antibodies and preferential vaccination in the risk group of patients.

Cíl: Podělit se o první klinické zkušenosti s léčbou perorálním kladribinem formou analýzy dat z národního registru ReMuS®. Soubor a metodika: Předkládáme analýzu souboru všech pacientů, kteří zahájili léčbu perorálním kladribinem v období od 1. 9. 2018 do 31. 12. 2020, a detailnější analýzu podsouboru 222 pacientů, kteří užili plnou kumulativní dávku. Analýzy zahrnují relapsy, disabilitu, zaměstnanost a sociální dávky, v podsouboru pak také MR aktivitu. Data byla získána ze všech 15 center pro léčbu demyelinizačních onemocnění a vyhodnocena metodami deskriptivní statistiky. Výsledky: Celý soubor obsahuje 436 pacientů (75,5 % žen) věkového průměru 37,0 let a hmotnosti 71,9 kg. Průměrná doba trvání nemoci byla 8,4 roku, vstupní Expanded Disability Status Scale (EDSS) skóre 2,8, roční výskyt relapsů 1,07 před zahájením léčby. U 90 % pacientů nedošlo po 20,8 (90. kvantil) měsíce k progresi disability, v prvním a druhém roce po zahájení léčby zůstaly bez relapsu přibližně tři čtvrtiny pacientů. U 85 % pacientů v definované podskupině nedošlo k významné MR aktivitě. Změna léčby na jiný lék modifikující průběh nemoci proběhla u 12 pacientů. Závěr: V souladu s registračními studiemi ukazují naše data vysoký podíl pacientů bez relapsů, bez progrese postižení a bez aktivity na MR, dále pak velmi nízký podíl pacientů se změnou léčby.
Aim: Our objective was to share our first clinical experience with oral cladribine gathered through the analysis of data of the national ReMuS® registry. Patients and methods: Our sample includes data of all patients who initiated oral cladribine treatment since September 1, 2018 till December 31, 2020. We also analyzed, in more detail, the subgroup of 222 patients who were assumed to complete the full cumulative dose. Our analyses included relapses, disability, employment status and financial social support, and also MRI activity in the subgroup. Data were obtained from all 15 centers for treatment of MS and analyzed in terms of descriptive statistics. Results: A total sample comprised of 436 patients, 75.5% of them females, mean age 37.0 years, and mean weight 71.9 kg. Mean duration since the disease onset was 8.4 years with a mean baseline EDSS (Expanded Disability Status Scale) score of 2.8. Mean annualized relapse rate was 1.07 prior to treatment initiation. After treatment initiation, the confirmed disability progression was not reached in 90% of patients until 20.8 (90th quantile) months after follow up. Approximately three quarters of patients stayed relapse-free in year one and two. In the defined subgroup, 85% of patients had no significant MRI activity. A switch to another disease-modifying drug was performed in 12 patients. Conclusion: In accordance with the pivotal trials, our data demonstrate a high proportion of patients without relapses, disability progression and MRI activity, and a very low proportion of patients with a treatment change.

BACKGROUND: Intrathecal IgM synthesis demonstrated either as cerebrospinal fluid (CSF)-restricted oligoclonal (o-) IgM bands or calculated using various formulas has been linked to more aggressive multiple sclerosis (MS) course. However, the proportion of MS patients showing intrathecal IgM synthesis varies largely between studies. We aimed to explore the relation between different formulas and results of o-IgM, and to assess the frequency of o-IgM bands in an unselected series of samples. METHODS: 432 samples were analyzed for o-IgM, o-IgG and quantitative measures of IgM and IgG synthesis. IgM index and formulas of Reiber, Auer and Öhman were compared to the result of the o-IgM test. RESULTS: At the cut-off commonly used, the non-linear formulas for intrathecal synthesis were specific (>94%) but rather insensitive (<40% even at a cut-off of 4 CSF-restricted bands) compared to o-IgM. No significant difference was noted in the performance of different formulas. At a cut-off of 4 bands, 61% of MS patients, but none of the controls were positive for o-IgM. CONCLUSIONS: Formulas for intrathecal IgM synthesis are insensitive compared to o-IgM. We propose to evaluate samples with 2 or 3 extra-CSF IgM bands as borderline and only samples with 4 or more as definitely positive.

AIMS: To compare the sensitivity and specificity of CSF-restricted oligoclonal IgG and free light chains as markers of multiple sclerosis and other inflammatory neurological diseases. METHODS: 196 paired CSF and serum samples were examined for oligoclonal IgG and oligoclonal free light chains. The sensitivity and specificity of the tests were calculated and optimal cut-offs for the number of CSF-restricted oligoclonal bands were then determined by analysis of receiver operating characteristic curves. RESULTS: Optimal cut-off values were ≥5 IgG bands for multiple sclerosis, ≥4 IgG bands for inflammatory neurological disease, ≥6 free κ, and ≥2 free λ bands for both purposes. Using these cut-off values, sensitivities and specificities for multiple sclerosis were 83.8% and 91.3% for IgG, 83.8% and 81.0% for free κ, and 67.6% and 75.4% for free λ. For inflammatory neurological disease, sensitivities and specificities were 60.8% and 95.7% for IgG, 69.6% and 92.6% for free κ, and 64.8% and 86.2% for free λ. CONCLUSIONS: Although exact cut-off values may vary according to method, reporting borderline results as positive, may compromise the specificity of the test and should be avoided.. The detection of intrathecal free light chain synthesis may be of value especially when the oligoclonal IgG test is negative or borderline, even though its specificity is slightly lower.

Neurologické postižení je poměrně vzácná komplikace hepatitidy E. Uvedená kazuistika popisuje 52letého imunokompetentního muže s aseptickou meningitidou a mnohočetným postižením periferních nervů na horních končetinách typu mononeuropatia multiplex, u kterého byla sérologickým vyšetřením prokázána akutní virová hepatitida E. Navíc byl virus hepatitidy E zjištěn polymerázovou řetězovou reakcí v séru i likvoru (genotyp 3f). Pacient byl léčen pouze symptomaticky, po půl roce přetrvával mírný neurologický deficit. Infekci virem hepatitidy E je vhodné zvažovat u pacientů se současným neurologickým a jaterním postižením.
Neurological complications of acute hepatitis E are relatively rare. The case report describes mononeuropatia multiplex with aseptic meningitis in a 52‑year‑old immunocompetent man. Viral hepatitis E was confirmed serologically and by polymerase chain reaction from the blood and cerebrospinal fluid (genotype 3f). Symptomatic treatment was given. Residual neurological deficit persisted six months after the onset of the disease. Diagnostic of hepatitis E should be considered in patients with concurrent neurological symptoms and liver cytolysis. Key words: hepatitis E – mononeuropatia multiplex The authors declare they have no potential conflicts of interest concerning drugs, products, or services used in the study. The Editorial Board declares that the manuscript met the ICMJE “uniform requirements” for biomedical papers.
