Immunoproliferative small intestine disease (IPSID) / Mediterranean lymphoma

Primary small intestinal lymphomas and alpha-heavy chain disease: Mediterranean lymphomas with alpha-chain monoclonal gammopathy. Molecular analysis of t 9;14 p A 10cm long resection ofthe firstjejunal loop with adjacent mesentery and mesentenc lymph nodes. It has been frequently observed that patients have a prolonged duration of. Treatment of Alpha chain disease. Biopsy of any other visible abnormality.

ABCD sponsors treatment for those in need regardless of gender, race or creed, helping them to reach their full potential, to live life with dignity and to take their rightful place in their community. Author information Article notes Copyright and License information Disclaimer. Primaiy small intestinal lymphoma in the endemic countries is commonly associated with IPSID and hence has been called Mediterranean lymphoma This abnormal protein is produced by the lymphoplasmacytic cells that infiltrate the intestinal mucosa and acts as a laboratory marker for IPSID pmtein compnses theas heavy chain immunoglobulins and lacks conjoint light chains.

It has been suggested that when laparotomy is planned, following procedures should be carried out: A report of 40 cases from Iran. Hematol Oncol Clin North Am. This journal is a member of and subscribes to the principles of the Committee on Publication Ethics. A year-old male patient presented with complaints of weight loss, small bowel type diarrhoea, features of malabsorption, and pedal oedema. The more malignant cells usually evolve from the same previously established clone Although equal sex distribution has been suggested, a male prepoaderance and no racial predilection are quite characteristic In some patients abnormal heavy chains are not detectable in the serum, however, they can still be demonstrated on the abnonnal lymphoplasmacytic cells.


Presence of immunoblasts in stage B disease is an interesting fmding. The deletion involves the VH region variable region of immunoglobulin heavy chain gene and CHl region first segment, constant region of immunoglobulin heavy chain gene.

Does IPSID develop in the individuals with pre-existing immunologic defects who are unable to control lymphoid proliferation in the gut in response to bacterial and parasitic antigens?

Molecular and immunohistochemical studies demonstrated an association with Campylobacter jejuni. Subsequently most cases are characterized by a loss of ability to synthesize light chains. Patients present with abdominal pain, malabsorption, diarrhoea, and weight loss of months to years duration. Pathologic hallmark is diffuse and extensive lymphoplasmacytic infiltration in small intestinal mucosa particularly duodenum and proxinialjejunum.

Distinguishing immunoprolifedative chronic inflammation from early-stage IPSID may be difficult, particularly on a small biopsy.

Non-secretory alpha-chain disease in intestinal lymphoma. Serum protein electrophoresis SPE with immunofixation was subsequently carried out, which showed a distinct band in the IgA region but without corresponding light chains Figure 5. The corresponding mRNA lacks the variable heavy chain V H and the constant heavy chain 1 C H 1 sequences and contains deletions as well as insertions of unknown origin.

It also allows the patient to be placed in one of three well defined stages. Although use of antibiotics may be beneficial in patients with stage A disease, repeat biopsies are indicated in those who fail to respond orundergo relapse oftheirsymptoms.


Immunoproliferative small intestinal disease (IPSID): a model for mature B-cell neoplasms.

Stomach and large intestinal involvement is rare. The disease usually effects the duodenum and proximal jejunum but ileal and pan- intestinal involvement may also occur Two wedge biopsy specimens from the ends of the duodenum and immuboproliferative respectively. Funding is constantly needed for new projects and to update and refurbish existing facilities. The presence of postage stamp like mucosal folds strongly suggests IPSID related small intestinal lymphoma.

Patients are often treated empirically for several presumptive diagnoses which vary from amebiasis to intestinal tuberculosis. Is it an ethnic disorder?

Cytogenetic abnormalities have been reported in rare single cases. Immunoproliferative small intestinal disease and primary small intestinal lymphoma: Please review our privacy policy.

Immunoproliferative small intestinal disease (IPSID): a model for mature B-cell neoplasms.

Behaviour of mixed variety NHIL is dependent upon the extent of more aggressive diffuse component IPSID lymphomas reveal excessive plasma cell differentiation and produce truncated alpha heavy chain proteins lacking the light chains as well as the first constant domain.

It is important to realize that pathologic appearance of the biopsy specimenvaries with the depth; the most abnormal cells being farthest from the mucosa. About Us Contact Us. Patient was treated with cap doxycycline and showed significant improvement.
