Rapidly progressive dementia and intractable diarrhea: a teaching case report and a systematic review of cognitive impairment in Whipple's disease.

ABSTRACT:

Objective

Whipple's disease (WD) is a systemic, chronic, relapsing disease caused by Tropheryma whipplei, which can mimic signs and symptoms of various clinical entities. Typical manifestations are represented by gastrointestinal and systemic symptoms, among which neurological ones are frequent. We present the case of a patient with WD and rapidly progressive cognitive impairment and a review of literature aimed to report epidemiological, clinical, neuroimaging, and laboratory findings of cognitive impairment associated with WD.

Methods

A systematic review of medical literature published until November 22, 2020, was performed. Full-text, peer-reviewed case reports and series in English language presenting patients with WD and cognitive impairment were included. Data concerning demographic, clinical, neuroimaging, and laboratory characteristics were collected and synthesized qualitatively.

Results

The patient was a 54-year-old male who developed rapidly progressive dementia, fluctuating arousal disturbances, and supranuclear ophthalmoparesis associated with chronic diarrhea and fever spikes. T. whipplei was detected in the cerebrospinal fluid, and appropriate antimicrobial therapy was given with progressive clinical benefit. The systematic review of 114 case reports/series identified 147 patients with WD and cognitive impairment; this latter was rarely isolated. Neurological symptoms associated with cognitive decline were psychiatric disturbances, supranuclear ophthalmoplegia, hypothalamic involvement, and consciousness disorders. Brain imaging and cerebrospinal fluid findings were heterogeneous and nonspecific.

Conclusions

Cognitive impairment represents one of the most common neurological features associated with WD. The clinical suspicion of this disease in patients with rapidly progressive dementia is crucial to guide diagnostic strategies and proper antimicrobial therapy, which may revert the clinical deterioration.

Project description:BackgroundMild cognitive impairment and cognitive impairment, no dementia, are emerging terms that encompass the clinical state between normal cognition and dementia in elderly people. Controversy surrounds their characterization, definition and application in clinical practice. In this article, we provide physicians with practical guidance on the definition, diagnosis and treatment of mild cognitive impairment and cognitive impairment, no dementia, based on recommendations from the Third Canadian Consensus Conference on the Diagnosis and Treatment of Dementia, held in March 2006.MethodsWe developed evidence-based guidelines using systematic literature searches, with specific criteria for study selection and quality assessment, and a clear and transparent decision-making process. We selected studies published from January 1996 to December 2005 that had mild cognitive impairment or cognitive impairment, no dementia, as the outcome. Subsequent to the conference, we searched for additional articles published between January 2006 and January 2008. We graded the strength of evidence using the criteria of the Canadian Task Force on Preventive Health Care.ResultsWe identified 2483 articles, of which 314 were considered to be relevant and of good or fair quality. From a synthesis of the evidence in these studies, we made 16 recommendations. In brief, family physicians should be aware that most types of dementia are preceded by a recognizable phase of mild cognitive decline. They should be familiar with the concepts of mild cognitive impairment and of cognitive impairment, no dementia. Patients with these conditions should be closely monitored because of their increased risk for dementia. Leisure activities, cognitive stimulation and physical activity could be promoted as part of a healthy lifestyle in elderly people and those with mild cognitive impairment. Vascular risk factors should be treated optimally. No other specific therapies can yet be recommended.InterpretationPhysicians will increasingly see elderly patients with mild memory loss, and learning an approach to diagnosing states such as mild cognitive impairment is now warranted. Close monitoring for progression to dementia, promotion of a healthy lifestyle and treatment of vascular risk factors are recommended for the management of patients with mild cognitive impairment.
