RESUMO
Secondary amyloidosis is a rare but serious complication of inflammatory bowel disease that may influence the prognosis even more than the underlying disease. Due to a better knowledge of the association of secondary amyloidosis to inflammatory bowel disease, early diagnosis of this complication is becoming more frequent, but its treatment continues to pose a challenge. We report 4 cases of patients with Crohn´s disease and amyloidosis diagnosed in the inflammatory bowel disease Units of Toledo and Ciudad Real, which represent 0.68% of the patients with Crohn´s disease of our health areas. There have been not cases of amyloidosis in patients with ulcerative colitis. In our 4 patients the secondary amyloidosis was clearly related to Crohn´s disease,which was often of fistulising type. The predominant clinical picture of amyloidosis was nephrotic syndrome. The patients responded to medical and surgical treatment of Crohn´s disease and colchicine, which improved renal function in all cases except in one who required kidney transplantation.

Metastatic Crohn's disease is a granulomatous cutaneous lesion that appears in patients with Crohn's disease and is located in any skin area, separated from the lesions in the gastrointestinal tract. This entity is characterized by its heterogeneous behavior, both in its localization and clinical expression and in its effect on patients' quality of life. Histology is essential for diagnosis and shows non-caseating granulomas. There are no treatment guidelines and various therapeutic strategies have been employed, with variable response. In most patients, treatment with biological agents is highly effective. We describe three cases of metastatic Crohn's disease with the aim of analyzing the characteristics of this entity, which should always be included in the differential diagnosis of skin lesions in patients with Crohn's disease. A literature review is also provided.

INTRODUCTION: Most patients with uninvestigated dyspepsia are diagnosed with functional dyspepsia. Various types of Helicobacter pylori gastritis have been described, each of which is associated with a distinct natural history of the infection (i.e. a different risk of ulcer or gastric cancer). OBJECTIVE: To determine the clinical and pathological characteristics of patients with uninvestigated dyspepsia in our area and the prevalence of the distinct types of H. pylori gastritis among patients with functional dyspepsia. MATERIAL AND METHODS: Ninety-eight patients (47 men and 51 women, mean age 35.8+/-13 years) with uninvestigated dyspepsia were included in this study. All the patients completed the Dyspepsia-Related Health Scale and all patients underwent gastroscopy with biopsy and the C13-urea breath test. RESULTS: Fourteen patients had organic causes of dyspepsia and 78 had functional dyspepsia. Fifty-one patients with functional dyspepsia (65%) had H. pylori infection; of these, 27 had pangastritis, 21 had antrum-predominant gastritis, 2 had multifocal atrophic gastritis and 1 had normal gastric mucosa. Among uninfected patients, 2 had multifocal atrophic gastritis. CONCLUSIONS: The prevalence of functional dyspepsia in this series was 85%. Twenty-seven percent of patients with functional dyspepsia had a combination of H. pylori infection and antrum-predominant gastritis, the type of gastritis predisposing to duodenal ulcer. Only 5% of the patients had multifocal atrophic gastritis, which is associated with a high risk of gastric cancer.

OBJECTIVE: Noninvasive diagnosis of atrophic gastritis would help to identify individuals at increased risk of gastric carcinoma. In the present study, we evaluated the utility of a serological panel combining pepsinogen I and II, gastrin-17, and anti-Helicobacter pylori antibodies (Gastropanel) as a screening method for atrophic gastritis. PATIENTS AND METHODS: The serological panel was evaluated in 56 patients divided in two groups: group 1 consisted of 47 patients with uninvestigated dyspepsia and group 2 was composed of nine consecutive patients with gastric carcinoma. In all patients, we performed endoscopy with biopsies of the gastric antrum and body. Levels of pepsinogen I and II, gastrin-17, and anti-H. pylori antibodies were determined through a specific EIA test (Biohit plc, Helsinki, Finland) in fasting serum samples. RESULTS: Atrophic gastritis was significantly more frequent in patients with gastric carcinoma than in those with dyspepsia (56 vs 6%; p = 0.0015). Agreement between the Gastropanel and gastric histology was good (kappa = 0.68). The sensitivity and specificity of the Gastropanel in the diagnosis of atrophic gastritis was 87.5% and 100%, respectively. However, the Gastropanel would not have detected four of the nine cases of gastric carcinoma, since these tumors arose in stomachs with nonatrophic mucosa. CONCLUSIONS: Gastropanel is a useful noninvasive method for the diagnosis of atrophic gastritis. However, its utility as a screening method is limited by cases of gastric carcinoma that arise in stomachs without atrophic mucosa.
