ABSTRACT
Objective:To analyze the clinical features and auxiliary examination results of sporadic Creutzfeldt-Jakob disease (sCJD) with restless leg syndrome (RLS) as the first symptom.Methods:The clinical features and auxiliary examination results of one case of sCJD who received treatment in Sichuan Mianyang 404 Hospital were analyzed based on relevant literature.Results:A 59-year-old woman of Han nationality who had sCJD with restless leg-like manifestation of the left lower limb for 18 days was included in this study. The patient was first treated in orthopedic department, but her symptom did not improve after treatment. Twenty days later, she was transferred to neurology department for further treatment. Her daily life and activities were not affected. Head magnetic resonance imaging, electroencephalography, cerebrospinal fluid routine examination and biochemical test results were normal. Five days later, the patient had mild left-sided ataxia, which then progressed rapidly, followed by right-sided ataxia, left-leg spasticity and adduction, involuntary movement, myoclonia, cognitive decline, akinetic mutism, repeated hyperthermia, repeated complex partial seizures. Two weeks later, head magnetic resonance imaging examination revealed hyperintense signal of the cingulate gyrus, frontal cortex and right island cortex on DWI, with cerebellar atrophy and three-phase electroencephalography wave. Four weeks later, CSF14-3-3 protein was positive, and no related genetic mutation in the prion protein gene was found. The duration from onset to death was about 8 months.Conclusion:sCJD is a common subtype of prion protein disease, and the condition can be stabilized for more than 1 month after the onset of RLS. There is no specificity in early clinical and auxiliary examinations, and neither dobutazine treatment nor neurotrophic treatment is effective. The disease progresses rapidly after 1 month, head MRI and EEG reexamination can reveal clues, and CSF14-3-3 protein can assist clinical diagnosis.
ABSTRACT
Creutzfeldt-Jakob disease (CJD) is a rare spongiform encephalopathy characterized by a rapid neurodegenerative progress, caused by a misfolded variant of the cellular prion protein (PrP) known as PrPSc. The clinical presentation of sCJD includes a wide range of neurological signs of cortical, subcortical, or cerebellar origin, either isolated or in various combinations. Due to this protean clinical presentation form, sCJD must be distinguished from other dementias. In this case report, we discuss the Heidenhain variant of Creutzfeldt-Jakob disease (HvCJD), a rare variant characterized by early visual symptoms and typical findings in imaging scans. Our patient presented rapidly progressive dementia and a history of visual hallucinations. As for other prion diseases, only symptomatic treatment is available for HvCJD. Thirty years of clinical investigation of patients with prion disease have resulted in little progress in either defining or evaluating potential treatments.
A doença de Creutzfeldt-Jakob (DCJ) é uma encefalopatia rara caracterizada por rápida progressão neurodegenerativa, causada pelo enovelamento incorreto da proteína priônica celular (PrP), conhecido como PrPSc. O quadro clínico da DCJ esporádica inclui um amplo espectro de sinais neurológicos de origens cortical, subcortical ou cerebelar, seja de forma isolada, seja combinada. Por causa da sua apresentação clínica variável, a DCJ esporádica deve ser distinguida de outras demências. Neste relato de caso, discutimos a variante Heidenhain da DCJ (vHDCJ), uma variante rara caracterizada por sintomas visuais precoces e características específicas no exame de imagem. Nossa paciente apresentou demência rapidamente progressiva e histórico de alucinações visuais. Assim como para as demais doenças priônicas, apenas o tratamento sintomático está disponível para a vHDCJ. Trinta anos de investigação clínica de pacientes com doença priônica têm resultado em pouco progresso, seja definindo os potenciais tratamentos, seja avaliando-os.

As doenças priônicas fazem parte do grupo das síndromes de demência rapidamente progressiva com neurodegeneração. Em humanos, a doença de Creutzfeldt-Jakob é a mais prevalente. Atualmente, seu diagnóstico pode ser baseado em uma combinação do quadro clínico, ressonância magnética e eletroencefalograma com alterações típicas, juntamente da detecção de proteína 14- 3-3 no líquido cefalorraquidiano. Este relato descreve o caso de uma paciente de 74 anos, natural de Ubá (MG), admitida em um hospital da mesma cidade com quadro de demência de rápida progressão, com declínio cognitivo, ataxia cerebelar e mioclonias. No contexto clínico, aventou-se a possibilidade de doença de Creutzfeldt-Jakob e, então, foi iniciada investigação para tal, com base nos critérios diagnósticos. Também foram realizados exames para descartar a possibilidade de doenças com sintomas semelhantes. O caso foi diagnosticado como forma esporádica de doença de Creutzfeldt-Jakob. (AU)
Prion diseases are part of the rapidly progressive dementia syndromes with neurodegeneration. In humans, Creutzfeldt-Jakob disease is the most prevalent. Currently, its diagnosis may be based on a combination of clinical picture, magnetic resonance imaging, and electroencephalogram with typical changes, along with the detection of 14-3-3 protein in cerebrospinal fluid. This report describes the case of a 74-year-old woman from the city of Ubá, in the state of Minas Gerais, who was admitted to a hospital in the same city with a rapidly progressive dementia, cognitive decline, cerebellar ataxia and myoclonus. In the clinical context, the possibility of Creutzfeldt-Jakob disease was raised, and then investigation was started for this disease, based on the its diagnostic criteria. Tests have also been conducted to rule out the possibility of diseases with similar symptoms. The case was diagnosed as a sporadic form of Creutzfeldt-Jakob disease. (AU)
