RESUMO
BACKGROUND: Restless legs syndrome (RLS) is one of the most common and burdensome sleep disorders in the course of multiple sclerosis (MS). OBJECTIVE: To evaluate common MS-related symptoms and consequences between groups with and without RLS and further assess the association of quality of life determinants with RLS symptom severity. METHODS: According to their RLS status, 46 relapsing-remitting MS patients were divided into MS-RLS+ (n=19) and MS-RLS- groups (n=27). Specific questionnaires were administered to assess the patients' health-related quality of life (HRQoL), fatigue levels, sleep quality, daily sleepiness, anxiety, and depression symptoms. Functional capacity was examined using the Expanded Disability Status Scale (EDSS). RESULTS: The prevalence of RLS was 41.3%. Compared to the MS-RLS- group, those with RLS had higher EDSS scores, more cranial and spinal lesions, longer disease duration, and were older. In the MS-RLS+ group, symptom severity scores were positively correlated with higher anxiety and poorer sleep quality. The symptom severity score was negatively correlated with mental HRQoL and pain scores. CONCLUSION: In conclusion, the findings of the current study indicate the negative impact of RLS on functional capacity, anxiety, sleep quality, and mental HRQoL of MS patients. Further studies using more accurate diagnostic strategies for identifying RLS and other sleep disorders are necessary to clarify the association of MS with RLS and explore relevant clinical implications.

BACKGROUND: Guillain-Barre syndrome is an acute immune-mediated polyneuropathy characterized by rapidly evolving symptoms and disability. Cerebrospinal fluid analysis and electrophysiological studies are crucial in the diagnosis of this syndrome. OBJECTIVE: To evaluate the prognostic value of the type and number of demyelinating findings and cerebrospinal fluid protein levels in patients with acute inflammatory demyelinating polyneuropathy. METHODS: We retrospectively analyzed electrophysiological data and cerebrospinal fluid of 67 consecutive patients with acute inflammatory demyelinating polyneuropathy from Istanbul, Turkey (2011-2019) studied ≤ 24 hours post-onset. RESULTS: The patients who met a higher number of demyelinating criteria had increased disability scores in the first day and first month, and higher cerebrospinal fluid protein levels were correlated with worse prognosis both on the first day and the first month. However, the disability scores did not correlate with any single specific criterion, and no significant correlation was found between the number of satisfied criteria and cerebrospinal fluid protein levels. CONCLUSIONS: The number of demyelinating criteria that are met and high cerebrospinal fluid protein levels at the disease onset may be valuable prognostic markers. More systematic studies conducted with serial nerve conduction studies are required to highlight the roles of the suggested criteria in clinical practice.

RESUMO Introdução: A síndrome de Guillain-Barré é uma polineuropatia imunomediada aguda caracterizada por sintomas e incapacidade em rápida evolução. A análise do líquido cefalorraquidiano e os estudos eletrofisiológicos são cruciais no diagnóstico dessa síndrome. Objetivo: Avaliar o valor prognóstico do tipo e número de achados desmielinizantes e dos níveis de proteínas do líquido cefalorraquidiano em pacientes com polineuropatia desmielinizante inflamatória aguda. Métodos: Analisamos retrospectivamente dados eletrofisiológicos e líquido cefalorraquidiano de 67 pacientes consecutivos com polineuropatia desmielinizante inflamatória aguda de Istambul, Turquia (2011-2019), estudados ≤24 horas após o início. Resultados: Os pacientes que atenderam a um número maior de critérios desmielinizantes apresentaram escores de incapacidade aumentados no primeiro dia e no primeiro mês, e níveis mais altos de proteína do líquido cefalorraquidiano foram correlacionados com pior prognóstico no primeiro dia e no primeiro mês. No entanto, os escores de incapacidade não se correlacionaram com nenhum critério específico e não foi encontrada correlação significativa entre o número de critérios satisfeitos e os níveis de proteína do líquido cefalorraquidiano. Conclusões: O número de critérios desmielinizantes atendidos e altos níveis de proteína no líquido cefalorraquidiano no início da doença podem ser marcadores prognósticos valiosos. Estudos mais sistemáticos conduzidos com estudos de condução nervosa em série são necessários para destacar os papéis dos critérios sugeridos na prática clínica.
