- Whipple's disease is a rare infection caused by the bacterium Tropheryma whipplei. It was first reported in 1907 but the bacterium was not identified until 1991 and not cultured until 2000.
- Classic symptoms include weight loss, diarrhea, arthralgia or arthritis. Neurological involvement occurs in 10-40% of cases and can include cognitive changes, supranuclear ophthalmoplegia, and altered consciousness.
- T. whipplei can also cause heart infections in 17-55% of cases, with infiltration of the pericardium, myocardium, and endocardium. Endocarditis from T. whipplei is a potential cause of sudden

Adenopathy
Both patients with adenopathy were male, aged 33 and
39 years, respectively. One had a 3-year history of unexplained
polyarthritis; the other presented with meningoencephalitis with
suspicion of lymphoma before lymph node biopsy examination.
Arthralgia, but no gastrointestinal symptoms, was present for
both. Diagnosis was indicated by examination of a lymph node
biopsy using positive specific PCR, PAS-staining, and immuno-
histochemistry for T whipplei (Figure 1). For 1 of these patients,
specific PCR was also positive in blood, small-bowel biopsy,
saliva, and stool specimens.

Of the patients in the current study with
such infections, the majority presented with the well-known
classic WD (80%).72
Less frequently (11%), endocarditis was
reported; other localizations of T whipplei were occasionally
observed. Most of our patients with classic WD were middle-
6,10,29,32,47,72
improvement is possible and should not exclude the diagnos
classic WD. Moreover, the inefficacy of such treatment aga
polyarthritis that is sometimes observed should lead to suspi
of T whipplei infection.
In future cases in which, after initiation of immuno
pressive therapy, patients with inflammatory rheumatoid dis
develop severe general involvement or the therapy is ineffec
against polyarthritis, we strongly suggest screening for cla
WD. PCR screening of saliva and stool specimens should
performed first, followed by a new, recently developed stra
that allows a noninvasive procedure.19
When results of both t
are positive, diagnosis of WD is highly suspected (93% of
cases in the current study).22
Small-bowel biopsy should
performed to confirm the diagnosis. When the results of the P
screening are negative, classic WD is unlikely.22
After initiation of immunosuppressive therapy, some pati
quickly developed other cardinal signs of classic WD includ
diarrhea and weight loss.32,42,69
Among other symptoms of
gestive involvement,10,24,47,72
abdominal pain is frequent. L
frequently, ascites, hepatomegaly, or splenomegaly have b
described.10,29,47,72
Mesenteric lymph nodes (17%) represent
of the major lymphadenopathic sites of involvement.
Differential diagnosis such as lymphoma or sarcoid
should be suspected in the presence of well-described pseu
tumoral involvement with mediastinal, mesenteric, and,
frequently, peripheral lymph nodes.10,24,47,72
Although lymph
should be easily differentiated by histologic analysis of lym
node biopsy, differential diagnosis with sarcoidosis may be d
cult because noncaseating epithelioid and giant-cell granulo

in approximately 10% of patien

An inappropriate maturation of professional antigen-presenting cells caused by the presence of interleukin 10 and interleukin 16, and the absence of interferon γ and
interleukin 12 might lead to insufficient antigen-presentation and inhibit the stimulation of antigen-specificT-helper type 1 cells enabling growth and systemic
spread of T whipplei.The local production of inflammatory cytokines through macrophages and endothelial cells in the periphery might induce lymphocyte
infiltration through a leaky endothelial barrier followed by focal inflammation even in immunologically protected tissues such as joints or the brain. CCL=chemokine

Figure 2. Strategy for the Diagnosis of Whipple’s Disease Using PAS Staining and PCR Assay.
The sampling hierarchy depends on the clinical manifestations of the disease and the interpretation of the obtained
results. If PAS staining of the small-bowel–biopsy specimen is positive and the PCR assay is negative, the diagnosis of
Whipple’s disease must be confirmed; this can be done by immunohistochemical testing with an antibody to T. whipplei.
If this test is positive, Whipple’s disease is confirmed; if the test is not feasible, other tissues must be analyzed. If
the PCR assay is positive and PAS staining is negative, the result must be confirmed by using another PCR target on
the same sample or by analyzing other tissues. When a definite diagnosis of Whipple’s disease has been established,
the cerebrospinal fluid should be tested with a PCR assay, even in the absence of neurologic signs. When the diagnosis
is in doubt, samples from saliva, stool, and blood can be tested; a positive PCR assay with one of these samples in
conjunction with a positive test on another tissue may be helpful in confirming Whipple’s disease.

30. of the 84 patients (96%) tested by PCR for T whipplei in ou
laboratory on duodenal biopsy were positive. PCR for Twhipple
was also performed on other tissue samples. Thirty-two of 61
blood samples (52%) tested by specific PCR were positive, as
were 43 of 51 stool specimens (84%), 43 of 63 saliva samples
(68%), and 21 of 45 cerebrospinal fluid (CSF) samples (47%)
Twelve CSF samples (39%) from 31 patients who did not have
clinical neurologic manifestations were positive. Specific PCR
performed on either stool or saliva was positive for 38 of the
41 patients (93%) tested.
Localized Tropheryma whipplei Infections
Endocarditis
All 16 patients (100%) with endocarditis were male (Table 5)
The mean age was 60.2 years (range, 42Y71 yr). Among them
5 (31%) patients had been previously treated with immunosup
pressive therapy, including 2 (12%) who were treated with tumo
necrosis factor inhibitor for rheumatoid disease. Five patients
(31%) had known valvular heart disease.
At the time of diagnosis, arthralgia was noted in 11 patients
(69%), congestive heart failure occurred in 8 patients (50%)
acute ischemic stroke in 6 (37%), and peripheral arterial embo
lism in 2 (19%). Only 4 patients (25%) presented with fever, and
3 patients (19%) experienced weight loss.
Nine patients (56%) had involvement of an aortic valve
The mitral valve was involved in 2 patients (12%), both the aortic
and the mitral valve in 4 patients (25%), and both the tricuspid
and aortic valve in 1 patient (6%).
All diagnoses were performed by heart valve analysis
Histologic analysis was positive for 11 patients (Figure 1). Fo

After the start of antibiotic therapy, 2 patients underwent
deterioration of their clinical state, with the appearance of ery-
thema nodosum-like lesions. An immune reconstitution inflam-
matory syndrome was diagnosed. One of these 2 patients was
previously reported.35
Routine Laboratory Investigations
Data were available for 83 patients. Among them, increased
erythrocyte sedimentation rate or C-reactive protein was present
in 70 patients (84%), and anemia in 50 patients (60%).

Nonetheless, as predicted from genomic analysis,
trimethoprim alone is not effective,80,81
since T whipplei
lacks the coding sequence for dihydrofolate reductase,
the target for the antibiotic.124
Doxycycline alone seems
to be rather bacteriostatic than bacteriocidal, although
the addition of hydroxychloroquine makes doxycycline
bacteriocidal.80,123
Notably, CNS relapse may occur even
while the patient is taking co-trimoxazole.125,126
Some
Neurological defects are difficult to reverse, especially
in patients with CNS symptoms. Although non-specific
focal lesions of the brain,15
ophthalmoplegia, and other
movement disorders respond well to antibiotic
treatment, other structural changes such as infarcts,
abscesses, or atrophic changes often persist, because
they often result from irreversible tissue damage and
therefore cannot be reversed by prolonged antibiotic

only a few scattered PAS-positive macrophages in 17 of
18 patients. The corresponding result in the meropenem
group was no or a few PAS-positive macrophages in 17 of
18 patients after a mean follow-up period of evaluation
of 39.8 Ϯ 10.2 months (range, 24–69 mo). The residual
macrophages were of type 3, rarely type 4. In one patient
in each group, more than a few PAS-positive macro-
phages were present at the last follow-up biopsy. These
macrophages were also of subtypes 2 and 3. In one of
these patients, the last biopsy was performed only 6
months after initiation of therapy. Four years later, this
patient is clinically well, but did not consent to another
endoscopy.
The courses of sedimentation rate and of hemoglobin
concentration as laboratory indicators of inflammation,
disease activity, and chronicity are depicted in Figures 2
and 3.
In all patients, clinical, laboratory, and histopathologic
remission was maintained at least up to the time of the
last endoscopy, performed approximately 40 months af-
ter initial treatment.
Cerebrospinal fluid obtained at study entry was avail-
able for examination with PCR in 26 patients; in 10 of
them an infection with T whipplei was detected.
Six months after intravenous antibiotic therapy (6 pa-
tients treated with ceftriaxone and 4 patients treated with
meropenem), T whipplei was no longer detectable in the
cerebrospinal fluid by PCR in any of these patients. My-
oclonus, the cognitive defect, and, uveitis had resolved;
polyneuropathy remained unchanged.
Thirty-six months after initial treatment, all patients
who at trial entry had presented with T whipplei in the
cerebrospinal fluid were advised to have a repeat spinal
fluid examination. Three patients declined and in 7 pa-
tients the PCR for T whipplei was negative 3–5 years after
treatment. However, in 1 patient initially treated with
ceftriaxone, the PCR in the cerebrospinal fluid was again
considered a treatment failure of both treatment arms.
His cerebrospinal infection was eradicated by additional
therapy (see later).
After termination of the clinical and endoscopic fol-
low-up examinations per protocol for 36 months, clinical
observation of the patients was continued without biop-
sies until the time of writing. The median overall fol-
low-up time was 89 months at the time of writing this
article (range, 71–126 mo). There has been no evidence of
recurrent Whipple’s disease.
The odds ratio for the composite end point remission
maintained for 3 years was 0.95 and the 95% confidence
interval was 0.05–16.29 (P ϭ 1.0).
Secondary Outcome Measures
At trial entry, PAS-positive macrophages, the hall-
mark of the diagnosis, were undetectable in the duodenal
Figure 4. Kaplan–Meier estimate of the time course to remission in tissue
samples in the 2 groups of the randomized controlled trial. Ongoing remis-
sion in the biopsy specimens is defined microscopically by transformation
from the PAS-stained subtype 1 macrophages to the subtypes 2 and 3
(see text for detail). Vertical bars denote 95% confidence intervals, depicted
in the Figure as one-sided to avoid overlapping. There is no significant
difference in the time course of histological remission.

vide new opportunities for investigating, under-
standing, and treating Whipple’s disease. The res-
ervoir of T. whipplei remains to be established, and
transmission mechanisms remain to be elucidat-
ed. The significance of possible asymptomatic
carriers must be clearly addressed. Isolates of
T. whipplei should be routinely genotyped to iden-
tify associations among clinical forms, different
strains, and geographic origin. Although PCR has
expanded the recognized clinical spectrum of the
disease, many facets remain elusive. In the future,
the development of an assay for detection of spe-
cific antibodies in the serum may help with diag-
nosis of the disease. Improvement in diagnostic
approaches is of paramount importance for reli-
