BACKGROUND Secretory immunity is a major defence mechanism against infections at mucosal surfaces which are common in HIV infected patients. AIMS To analyse intestinal immunoglobulin production in HIV infection in comparison with that in saliva and serum. PATIENTS AND METHODS Immunoglobulin G (IgG), A (IgA), and M (IgM) concentrations were determined in supernatants of short term cultured d...

BACKGROUND Duodenal biopsy is required for diagnosis of celiac disease in adults, although some studies have suggested adequate accuracy of serology alone. OBJECTIVE We aimed to assess the correlation between anti-tissue transglutaminase (tTG) titer and pathological findings and to define the specific level of tTG for predicting celiac disease in adults without the need for biopsy sampling. M...

Celiac disease (CD) is treated by eliminating all gluten from the diet. A 49-year-old man with CD was admitted to our clinic with complaints of recurrent diarrhea and abdominal pain despite strict adherence to a gluten-free diet. The duodenum was seen to be edematous on gastroduodenoscopic examination. Histological examination of the biopsy specimen taken from the duodenum showed multiple round...

We report a rare case of secondary renal amyloidosis in a patient with probable celiac disease presenting as nephrotic syndrome. A 30-year-old man with chronic diarrhea presented with progressive anasarca for 2 years. On further evaluation, he had hypoalbuminemia, significant nephrotic-range proteinuria, and elevated levels of anti-tissue transglutaminase. Renal biopsy suggested deposition of a...

Renal cell carcinoma (RCC) metastasis to duodenum is very rare and only a few case reports are available in the literature. We here reported a patient with solitary duodenal metastasis presented with melena six years after right nephrectomy. The patient underwent upper gastrointestinal endoscopy showing ulcerative mass at the second portion of duodenum and biopsy of this mass was consistent wit...

To this day intestinal biopsy is justly considered the "gold standard" for the diagnosis of coeliac disease (CD). The aim of the authors in setting up these guidelines was to assist pathologists in formulating a more precise morphological evaluation of a duodenal biopsy in the light of clinical and laboratory data, to prepare histological samples with correctly oriented biopsies and in the diff...

Primary gastric lymphoma, an uncommon gastric tumor caused by infection with Helicobacter pylori, is rarely associated with gastric amyloidosis. Chronic bacterial infection is known to cause amyloidosis. We report a 53-year-old man who had an antral and duodenal mass with narrowing and ulceration on endoscopy and CT scan; endoscopic biopsy revealed gastric amyloidosis. Rapid urease test and ser...

introduction: in ramadan, healthy adult muslims are obliged to fast. prolonged fasting increase gastric acid and pepsin levels, which promote the risk of duodenal ulcer perforation (dup). effects of ramadan fasting on dup have not been thoroughly studied yet, and the limited number of studies investigating the impact of ramadan fasting on dup yielded discrepant results. this study aimed to eval...

in endemic regions visceral leishmaniasis is one of the most common opportunistic infections in hiv positive patients. simultaneous infection with leishmania and hiv has been reported in some countries but there's no such report from iran in medical literature. patient was a 27-year-old man admitted with chief complaints of intermittent abdominal pain, anorexia and vomiting since 6 months ago. ...

Diagnosis of coeliac disease (CD) relies on a combination of clinical, genetic, serological and duodenal morphological findings. The ESPGHAN suggested that biopsy may not be necessary in all cases. New guidelines include omission of biopsy if the concentration of CD-specific antibodies exceeds 10 times the upper limit of normal (10 ULN) and other criteria are met. We analysed the 10 ULN criteri...
