An unusual case of insomnia associated with Whipple encephalopathy: first case reported from Greece

Sleep disorders of Whipple's disease of the brain

OBJECTIVE

To understand the effects of Whipple's disease (WD) of the brain on sleep function.

METHODS

Clinical and polysomnographic studies of two patients with severe disruption of sleep due to WD: a 48-year-old female with primary WD of the brain and a 41-year-old male with secondary WD of the brain.

RESULTS

The patient with primary WD had hypersomnolence with severe obstructive sleep apnoea, reduced sleep efficiency, frequent waking and sleep fragmentation. The patient with secondary WD was also hypersomnolent with oculomastictory myorhythmia. He was shown to have severe sleep initiation insomnia with poor sleep efficiency, severe obstructive sleep apnoea/hypopnoea and oculomasticatory myorhythmia at sleep-wake transitions.

CONCLUSION

WD of the brain may affect sleep biology in its primary and secondary forms leading to hypersomnolence from obstructive sleep apnoea, sleep fragmentation, reduced sleep efficiency, sleep initiation insomnia and intrusive oculomasticatory myorhythmia.

[Neurological complications of inflammatory bowel diseases]

Inflammatory bowel diseases, such as Crohn's disease, ulcerative colitis, autoantibody driven celiac disease and infectious Whipple's disease can all be associated with neurological symptoms. The neurological manifestation may occur even before the gastrointestinal symptoms or the enteropathic symptoms can even be absent as in celiac disease. These diseases can be caused by malresorption and lack of vitamins due to enteral inflammation as well as (auto-)immunological mechanisms and drug-associated side effects. Thus, inflammatory bowel diseases have to be considered in the differential diagnosis. In this review the most common neurological manifestations of these diseases will be described as well as the diagnostic approach.

[Whipple's disease. Do we think of it enough?]

Whipple's disease is a chronic, systemic, relapsing bacterial illness, which is always fatal without treatment, and means a diagnostic challenge for both clinicians and pathologists. It occurs in Caucasian, white, middle-aged men in 80 % of the cases.

CASE REPORT

The authors present three cases, and review the etiology, clinical features, presumed pathomechanism and the possibilities of treatment.

CONCLUSION

Several immune-mechanisms have been discussed in the background of Whipple's disease, but their primary or secondary role is yet undetermined. First of all, this is a gastrointestinal disease; however, extraintestinal symptoms may be present many years before the final diagnosis. The histological hallmark for the diagnosis is the presence of numerous macrophages in the duodenal mucosa showing periodic acid-Schiff (PAS)-positive inclusions, and the polymerase chain reaction. The choice of antibiotics and the length of the treatment is empiric, but in most cases there is an immediate response to therapy. Relapses are common, especially the involvements of central nervous system.

Premature ovarian failure in suspected Whipple's disease

INTRODUCTION

Whipple's disease is a relapsing systemic infectious disease probably caused by the Gram-positive bacillus Tropheryma whippelii. The diagnosis can be established based on the characteristic histopathological features found in the affected organ (foamy macrophages with a coarsely granular cytoplasm, which stains with PAS, and by means of polymerase chain reaction (PCR) technology).

CASE REPORT

We report a case of a 23-year-old woman affected by suspected Whipple's disease. She presented encephalopathy and neuropathy with inveterate hyperpyrexia and alteration of the hypothalamic-pituitary-ovary axe. She was amenorrheic because of an hypergonadotropic hypogonadism.

DISCUSSION

This hypogonadism is possibly due to follicular depletion caused by inveterate hyperpyrexia or T. whipplii localization.

Neurologic manifestations of Whipple’s disease

Whipple's disease is a rare, multisystem, infectious disorder caused by the bacterium Tropheryma whippelii. Patients with central nervous system (CNS) involvement may present in a variety of ways, including cognitive impairment, psychiatric manifestations, gaze palsies, upper motor neuron signs, and hypothalamic dysfunction. A tissue-based diagnosis of Whipple's disease is made based on the presence of periodic acid-Schiff-stained material or by the identification of bacterial RNA using polymerase chain reaction. To avoid relapse, patients should be treated with antimicrobial agents that penetrate the CNS, and therapy should be continued for at least 1 year.
