Most of these persons unfortunately die with uncontrolled malabsorption despite steroid therapy and parenteral nutrition discount clindamycin 150mg visa. This suggests that immunohistochemical changes represent a marker of poor prognosis buy clindamycin 150 mg line. Malignant Complications Some of the malignant complications are listed in Table 6 buy 150 mg clindamycin overnight delivery. The overall cancer risk in celiac disease is approximately double the rate in the general population. The two main malignancies in persons with celiac disease include adenocarcinoma or lymphoma of the small intestine. Some reports suggest that other sites in the gastrointestinal tract may have an increased rate of malignancy. In particular, hypopharyngeal cancer may occur, possibly in association with iron deficiency anemia. Small intestinal adenocarcinoma is an unusual malignancy, but, this cancer is markedly increased in adult celiac disease. These are usually located in the jejuno-ileum, although localization in the duodenum may occur. Like adenocarcinoma that occurs in the colon, an adenoma-to-carcinoma sequence has been proposed. Most often, however, adenocarcinoma occurring in the patient with celiac disease presents late in the clinical course, sometimes with symptoms of a small bowel obstruction. Surgical resection of the carcinoma has the greatest potential for cure, although adenomas and carcinomas may be multifocal and occur elsewhere in the small intestine, thereby presenting a surgical care. Although splenic atrophy is usually seen in adults, the development of splenomegaly may be a clinical clue to the development of an occult lymphoma. Rarely, the lymphoma may also develop in an extra- intestinal site or may be multifocal. Involvement of lungs or pleura, and thyroid with T-cell lymphoma in celiac disease has been described, possibly reflecting their common embryonic origins from the intestinal tract. Hepatosplenic T-cell lymphoma, an exceedingly rare entity, has also been reported in celiac disease without evidence of small bowel involvement with lymphoma. Often, surgical treatment is required for complications, particularly intestinal obstruction. Finally, there is some evidence, primarily from long-term studies in the United Kingdom, suggesting that the continued use of a gluten-free diet may be protective for the development of lymphoma in the person with celiac disease. A number of serological tests have been developed that may be helpful for screening for celiac disease. If celiac disease is suspected, a serologically-positive test may confirm suspicion of celiac disease, but a biopsy should be done to determine if changes of untreated celiac disease are present prior to initiating a gluten-free diet. The former is semi-quantitative whereas the latter is quantitative and may be automated. While both serological tests are highly sensitive, false-positive assays may occur in the absence of celiac disease (Table 8). In addition, the tests are not as helpful if selective IgA deficiency is present, as is the case in about 5% of the general population. This is why it is often recommended to perform a quantitative test for IgA when performing the IgA-anti tTg test. Standardized measurement of transglutaminase antibodies is necessary, because of the very wide range of laboratory sensitivities (69% to 93%) and specificities (96% to 100%) of this First Principles of Gastroenterology and Hepatology A. A standardized method of analysis is also needed to determine quantitatively to gluten content of food and to be certain that gluten-free truly represents an accepted low level of gluten (Thompson and Mendez 2008). Monosaccharides (mannitol) and disaccharides (lactulose, saccharose) molecules have been used to investigate intestinal permeability. The reason being for this is an increase in the absorption of lactulose (through the paracellular route) due to "leakiness" of the intestine and a reduction in the absorption of mannitol (through the transcellular route) due to a reduction in surface area as a result of villous atrophy 7. Shaffer 248 nucleotide polymorphisms suitable for high-throughput approaches gives sensitivities and specificities of 95% to 100% in European persons (Koskinen et al. Intraepithelial lymphocytosis also occurs, and the lamina propria region shows increased cellularity largely from plasma cells and lymphocytes. Some experts have termed this biopsy appearance as: crypt hyperplastic villous atrophy (severe flat lesion, Marsh 3 lesion). Over time, the clinical and histological changes revert to normal on a strict gluten-free diet. Most newly diagnosed sprue patients will notice clinical improvement within a few weeks. Histological evidence of improved architecture in the most proximal small intestine may take many months, even years, especially in adults. Shaffer 249 Less severe histopathological changes may occur in adult celiac disease and the changes may be patchy rather than diffuse. In some instances special stains may give a clue to the diagnosis of the small bowel condition (Table 13). Shaffer 253 In the patient with diarrhea and or flat malabsorption a novel small bowel biopsy will help to exclude several conditions (Table 13). A moderate lesion (partial villus atrophy) with less severe change in villus architecture may also occur. Often, these less severe changes are associated with other diseases, rather than celiac disease. A number of small bowel disorders may cause histological changes that appear like untreated celiac disease, but do not respond to a gluten-free diet. Only the biopsy changes of untreated celiac disease respond to a gluten-free diet. Shaffer 254 Others o Crohn disease o Graft-versus-host disease o Immunoproliferative diseases (lymphoma) o Zollinger-Ellison syndrome o Autoimmune enteropathy (? Treatment The essential element of management is strict and lifelong removal of gluten from the diet 8.

Knowledge of that evidence leads to knowledge and the application of key components such integration with patient-specifc factors that in turn lead as patient as person, biopsychosocial perspective, shared to collaborative determinationwith the patient and other decision-making, and patient-provider relationship. Those members of the health care teamof the most appropriate components can be enhanced by a thorough assessment of glycemic and nonglycemic goals of therapy.
