Plasma exchange in neurology patients-experience from single center in Montenegro

INTRODUCTION

Plasma exchange (PE) is widely used in many immune-based neurological diseases. Our aim is to analyze characteristics of PE in neurological patients at the Clinical Center of Montenegro.

METHODS

Our study involved neurological patients treated with PE between January 2020 and April 2022.

RESULTS

In total, 246 PEs were performed in 43 patients. We divided patients into 4 groups according to indications. In 8/9 multiple sclerosis (MS) patients a decrease of Expanded Dysability Status Scale at least 0.5 was verified. In 14/20 Guillain Barre syndrome patients reduction of Hughes was observed. Four patients with myasthenia gravis (MG) were treated with PE. The most heterogeneous group (4) consisted of patients in whom the mechanism of disease development is assumed to be immune system dysregulation. Fourteen patients had any adverse event.

CONCLUSION

Our results show that PE is widely used and safe in the treatment of neurological diseases.

Impact of the autonomic dysfunction on the quality of life in people with NMOSD and MS: An international cross-sectional study

BACKGROUND

A substantial autonomic nervous system (ANS) dysfunction has been described in multiple sclerosis (MS) and recently, also in neuromyelitis optica spectrum disorder (NMOSD). The prevalence of ANS symptoms contributes to the chronic symptom burden in both diseases. The aim of our study was to assess ANS dysfunction in people with (pw) NMOSD and MS, using the Composite Autonomic Symptom Score-31 (COMPASS-31), and additionally, to evaluate if ANS dysfunction have impact on the quality of life of these patients.

METHODS

We conducted cross-sectional study at three national referral neurological clinics in Serbia, Croatia, and Montenegro. A total of 180 consecutive subjects, 80 pwNMOSD and 100 pwMS, followed-up at these clinics, were enrolled in the study. Subjects included in the study completed: the validated versions of the COMPASS-31 and the Multiple Sclerosis Quality of Life-54 (MSQoL-54), and the Beck Depression Inventory (BDI).

RESULTS

This study demonstrated that the total COMPASS-31 score > 0.0, implicating the presence of ANS dysfunction, was detected in almost all NMOSD and MS study participants tested (80/80, and 97/100, respectively). Our findings showed that autonomic symptom burden was statistically significantly correlated with decreased quality of life, in both NMOSD and MS cohorts. The independent predictors of the better quality of life in pwNMOSD were lower autonomic burden, particularly the absence of the orthostatic intolerance (p = 0.005), along with lower EDSS and BDI score (p ≤ 0.001). Similarly, in pwMS, independent predictors were EDSS, BDI, orthostatic intolerance, and the total COMPASS-31 (p ≤ 0.001).

CONCLUSION

Our study demonstrated that a significant proportion of persons with both NMOSD and MS have considerable dysautonomic symptom burden which is correlated with the decreased quality of life. Further investigations are warranted in order to optimize treatment interventions in MS and NMOSD.

The User, the Watch, and the Bestseller: Study on the Utilization of Smart Medical Wearables and Their User Manuals

In this paper, we present a study on the utilization of smart medical wearables and the user manuals of such devices. A total of 342 individuals provided input for 18 questions that address user behavior in the investigated context and the connections between various assessments and preferences. The presented work clusters individuals based on their professional relation to user manuals and analyzes the obtained results separately for these groups.

Guillain-Barre Syndrome Followed by Covid-19 Infection, Vaccination and Other Precipitating Factors during the Pandemic

Background and Aims

Guillain-Barré syndrome (GBS) is usually triggered by an infection. Vaccination is mentioned as a possible trigger in a small number of GBS cases. The aim of this study was to notice GBS distinctness provoked by various triggers during the COVID-19 pandemic.

Material and Methods

A total of 109 GBS patients were divided into three groups, respectively: COVID-19 infection associated (19 patients), COVID-19 vaccination associated (16 patients) and precipitated by some other factors (74 patients). We compared the clinical, neurophysiological and laboratory characteristics of these three groups.

Results

Neither were differences recorded in the age of the patients of these three groups at the time of illness, nor in the number of days from the precipitating factor to the onset of symptoms. There were no clinical differences between groups related to severity of the disease or patients' recovery. The only clinical difference was observed in relation to facial nerve bilateral affection because it was significantly higher in the post-vaccination group. According to neurophysiological findings, demyelinating form dominated in all three groups.

Conclusion

Clinical characteristics, electrophysiological findings and laboratory characteristics did not differ significantly in Guillain-Barre syndrome followed by COVID-19 infection, vaccination and other precipitating factors during the pandemic. The bilateral involvement of facial nerves was significantly higher in the post-vaccination group. Most of these cases had a mild form of the disorder-distal paresthesias GBS variant.

Reorganization of multiple sclerosis health care system in Clinical Centre of Montenegro during the COVID-19 pandemic

The COVID-19 epidemic has brought a number of changes to health systems, including the provision of health services to patients with multiple sclerosis (MS). Work in the Clinic for Neurology of the Clinical Center of Montenegro (CN-CCM) with MS patients continued as much as possible during the epidemic. The administration of the already started disease-modifying therapy (DMT) continued, and the introduction of the new one was postponed until the moment when the epidemic started to slow down. During the epidemic period, plasmapheresis treatment was performed in CN-CCM without any complications. New ways of communications (special e-mail address and phone line) with MS patients during epidemic were realized. During epidemic, smaller number of relapses were reported compared to same period in 2019. There were not MS patients in Montenegro suffering from SARS-Cov2 virus infection.

Attitudes of patients with relapsing-remitting form of multiple sclerosis using disease-modifying drugs in Montenegro regarding COVID-19 pandemic

•

Montenegrin MS patients worry about disease and future in the era of SARS-Cov2.

•

Older MS patients show higher level of solicitude due to COVID-19 pandemic.

•

Female MS patients are not as worried about COVID-19 as male patients.

•

Patients using ocrelizumab show the highest level of fear about COVID-19.

•

MS patients in Montenegro show a high degree of trust in physicians.

Background

In the days of the reorganization of healthcare systems due to SARS-Cov2 pandemic, patients suffering from chronic diseases are being often neglected. The aim of our study was to examine the attitudes and behaviors of patient suffering from relapsing-remitting form of multiple sclerosis using disease-modifying drugs in Montenegro in relation to the current pandemic.

Methods

The research was conducted through an online-generated questionnaire during the peak of the pandemic.

Results

There is a high level of concern about COVID-19 (3.22±1.23), especially about safety behavior intensification (3.80±1.29). Possibility of relapse during pandemic was considered as moderate (2.06±1.42), but relapse symptoms would be reported by the majority of subjects (1.55±1.23). Our unemployed patients statistically more often reported that they had more frequent mood changes, but also that they felt more energy loss. Surprisingly, there was no difference among the subjects according to smoking status. According therapy groups there was significant difference between the groups regarding some variables: patients using ocrelizumab are most concerned about COVID-19; patients using interferon beta 1a i.m. statistically more often have frequent changes in their mood, memory problems, poor appetite, feeling of nausea or upset stomach and patients on fingolimod have bigger afraid of coming to regular visits.

Conclusion

Our patients showed concern about their disease future status in the current epidemic era, but also showed a high degree of trust in physicians and the overall health system.
