Whipple’s Disease932-1

History

A 44 year old woman with a past history of ethanol abuse was admitted in 1993 with a one year decline in memory, hypothalamic dysfunction and a one month history of diplopia and ataxia. A rapid decline in short term memory left her with an inability to recall what she had just read or recently eaten.

Nine months PTA she had an episode of excruciating abdominal pain. An IV pyelogram and CT of the abdomen were normal despite hematuria.

Six months PTA, she was admitted to the hospital because of increasing confusion and was noted to have upbeat nystagmus in primary gaze.

Whipple’s Diagnosis

Duodenal biopsy: PAS stain with diastase

Non-intestinal tissues: electron microscopy

Polymerase Chain Reaction:

– Tissue, blood, and other bodily fluids

In situ hybridization fluorescent rRNA probe

Whipple’s bacillus “Tropheryma whippelii”

Brain Biopsy #2

Open biopsy: wall of third ventricle

“Perivascular and parenchymal

infiltration with foamy macrophages which stained +ve for PAS.”

Brain tissue and small bowel biopsy insufficient for

PCR studies.

The causative organism Tropheryma whippelii is seen within macrophages in the parenchyma on PAS (peroidic acid-Schiff).

The causative organism Tropheryma whippelii is seen within macrophages in the parenchyma on silver stains.

Treatment

Ceftriaxone 2g IV bidor

PCN G procaine 1.2 mU IM qd +

Streptomycin 1g IM qd for 2 weeksthen

Trimethoprim-sulfamethoxazole 160/800 mg po bid 1x year
