Notes de l'éditeur
Some of these associated conditions include the following
Before we go on with the case, I want to make a couple of brief points about nonresponsives to GFD
The most obvious diagnosis is occult gluten ingestion and it doesn’t take that much gluten. IN 2007, catassi et al demonstrated that 50mg of gluten can elicit significant hisologic changes with a double randomnized placebo controlled where the randomized 49 biopsy proven celiac patient gfd to 0 , 10, 50mg for 90day and assesed histologic changes. Villous height/crypt depth were significantly different in the 50mg group. The little ditzle just how small 50mg of gluten is.
In 2007, leffler et al demonstrated that the etiology of non response to a gluten free diet includes possibilities beyond gluten ingestion/contamination
They reviewed the biopsy proven Celiac cases at Beth-Israel for non-responders
113 of 603 patients (19%) defined as non-responsive Celiac Disease
Non-responders defined as: looked at etiologies of nonresponsives
referral to a CD specialist for gluten non response
failure of clinical symptoms/lab abnormalities to improve in 6 mos on GFD
recurrence of symptoms and/or laboratory abnormalities on GFD

Refractory cd and non-responsive cd are not interchangble terms.
Refractory cd is defined persistent malabsorptive symptoms w/ villous atrophy despite GFD for 6-12 mos in the absence of other causes of nonresponsive celiac disease.

Final Pathologic DiagnosisMarked villous blunting with an increased subepithelial collagen layer,consistent with collagenous sprue and no morphologic or immunophenotypicevidence of either a T- or B-cell lymphoma, "second and third portion of theduodenum", biopsies-see microscopic descriptionjdJerome Dickstein, M.D., Ph.DInterpretation performed by the Attending Pathologist.Electronically Signed Out by Jerome Dickstein, M.D., Ph.DClinical HistoryThe patient is a 62-year-old female who undergoes biopsy of second and thirdportion of duodenum for a history of refractory celiac sprue, rule outenteropathy associated T-cell lymphoma- request for gene rearrangement.Microscopic DescriptionThe "second and third portion of the duodenum" show marked villous blunting, anincreased subepithelial collagen layer, consistent with collagenous sprue. Thereis a mild lymphoid infiltrate with a background of numerous plasma cells in thelamina propria. The lymphocytes are small to intermediate in size with slightlyirregular contours and a high N/C ratio. No significant increase inintraepithelial lymphocytes is seen. In order to further investigate for apossible lymphoproliferative disorder, immunohistochemical studies are conductedwith appropriately reacting controls. By far, T-cells comprise the majority ofthe lymphocyte population. T-cells are positive for CD3, CD4, CD5, CD7 and to alesser extent for CD8 immunostains. CD56 shows non-specific background staining,but lymphoid cells are clearly negative for this antibody stain. CD43 highlightsT-cells in a similar number and distribution as does the anti-CD3 antibodyimmunostain. CD20 immunostain outlines small numbers of singly scattered and asmall cluster of B-cells. The B-cell cluster is negative for CD43. In situhybridization for kappa and lambda mRNA demonstrates that the plasma cells arepolyclonal.Overall, the findings observed in this case are marke
FINAL PATHOLOGIC DIAGNOSISUpper GI endoscopic biopsies,Body:- Fundic mucosa without diagnostic abnormality.Antrum:- Antral mucosa without diagnostic abnormality.Duodenal bulb:- Duodenal mucosa with severe villous blunting and increasedsubepithelialcollagen layer, consistent with collagenous sprue.Duodenum:- Duodenal mucosa with severe villous blunting and increasedsubepithelialcollagen layer, consistent with collagenous sprue.
Looked at 10 normal patients biopsies
13 with total villous atrophy
No phenotypically aberrant intraepithelial lymphocytes
PCR showed 1 pt. with dominant T-cell clone
All lesions are Marsh type III in collagenous sprue. Grade III above atrophy, abc only differ in degree of atrophy.
