Diagnostic guidelines in central nervous system Whipple's disease
Elan D. Louis, Timothy Lynch, Philipp Antonio Kaufmann, Stanley Fahn, Jeffrey G. Odel. Annals of Neurology, 1996-10-01
Topic: Brain imaging, connectivity and assessment
Many cases of central nervous system (CNS) Whipple's disease are not diagnosed until postmortem. Few reviews of CNS Whipple's disease have delineated the frequencies of abnormalities on neurological examination, cerebrospinal fluid studies, neuroimaging, and intestinal biopsy studies. Guidelines for diagnosis and treatment have not been proposed. In this review we present 3 new cases of CNS Whipple's disease and summarize the literature to determine the frequencies of neurological signs and abnormalities on diagnostic testing. We propose guidelines for diagnostic screening, selection for biopsy, and treatment. Review of the 84 cases of CNS Whipple's disease (81 in the literature, 3 new) revealed that 80% of the patients had systemic signs. Cognitive changes were frequent (71%), and 47% with cognitive changes also had psychiatric signs. Oculomasticatory myorhythmia and oculo-facial-skeletal myorhythmia, pathognomic for CNS Whipple's disease, were present in 20% of patients, and were always accompanied by a supranuclear vertical gaze palsy. Tissue biopsy was a sensitive technique; 89% of those who had biopsies had positive biopsy results. Diagnosis and treatment of definite CNS Whipple's disease should be based on the presence of pathognomic signs (oculomasticatory myorhythmia or oculo-facial-skeletal myorhythmia) or positive biopsy or polymerase chain reaction results. Possible CNS Whipple's disease should be diagnosed in the setting of unexplained systemic symptoms and neurological signs (supranuclear vertical gaze palsy, rhythmic myoclonus, dementia with psychiatric symptoms, or hypothalamic manifestations). Those with possible CNS Whipple's disease should undergo small-bowel biopsy.
Key findings
- Review of the 84 cases of CNS Whipple's disease (81 in the literature, 3 new) revealed that 80% of the patients had systemic signs.
- Tissue biopsy was a sensitive technique; 89% of those who had biopsies had positive biopsy results.
- Diagnosis and treatment of definite CNS Whipple's disease should be based on the presence of pathognomic signs (oculomasticatory myorhythmia or oculo-facial-skeletal myorhythmia) or positive biopsy or polymerase chain reaction results.

How this study scored 40/100
Published in a leading specialty journal. Scored zero for study design, sample size, effect reported, studied in people and randomised / blinded because the record does not state it. We have no data on journal's citation record, times cited, citations per year, impact for its field and year, cited by studies here, still being cited, senior author's track record, institution's track record and multi-centre collaboration, so those were left out: it earned 23 of the 58 points we could judge it on, which is 40 out of 100.
