Resumen
CARDENAS-SAENZ, Omar et al. Experience with Creutzfeldt-Jakob disease in a single referral center in Mexico. Case series. Gac. Méd. Méx [online]. 2022, vol.158, n.6, pp.410-418. Epub 20-Ene-2023. ISSN 2696-1288. https://doi.org/10.24875/gmm.22000138.
Introduction:
Creutzfeldt-Jakob disease (CJD) is a rapidly progressive and fatal central nervous system disease caused by prions.
Objective:
To present the main clinical and paraclinical characteristics of patients with probable CJD in a referral center of Latin America.
Methods:
Retrospective study of patients diagnosed with rapidly progressive dementia between 2014 and 2019. Clinical, demographic, electroencephalogram, magnetic resonance imaging, and 14-3-3 protein characteristics were included, as well as positron-emission tomography (PET) data when available.
Results:
Twenty-four patients met the criteria for sporadic CJD (75% were women). Mean age was 59.29 ± 11.67 years, while mean disease duration from symptom onset to hospital admission was 7.41 ± 6.54 months. The most common first symptom was behavioral changes (41.7%). Delta wave complexes prevailed (54.2%) on electroencephalogram, cortical hyperintensity (83.3%) on magnetic resonance and frontal hypometabolism (37.5%) on PET. Seven cases showed positive total Tau; five, positive 14-3-3 protein; and three, positive phosphorylated tau on cerebrospinal fluid analysis.
Conclusions:
There is significant clinical heterogeneity regarding initial symptoms. Auxiliary test findings were consistent with those of other series.
