[Helicobacter pylori in esplenectomized patients with immune primary trombocytopenia].

Background: Primary Immune Thrombocytopenia (TIP) is an autoimmune disease that accelerates the peripheral destruction of platelets and alters megakaryocytopoiesis. Helicobacter pylori infection and eradication has been associated with an increase in the platelet count in patients with IPT. The aim of this article is to evaluate the platelet response after H.

L-[1-13C]phenylalanine breath test in patients with chronic liver disease of different etiologies.

The aim of this study was to compare the oxidation of L-[1-(13)C]phenylalanine ((13)C-PheOx) in patients with chronic liver failure due to different etiologies using L-[1-(13)C]phenylalanine breath test. Breath samples were collected before the administration of 100 mg L-[1-(13)C]phenylalanine, and every 10 min thereafter until completion of 1 h. Control subjects (n=9) presented a larger cumulative percentage of (13)C dose recovery (CPDR) than patients (n=124) with chronic liver disease, regardless of the etiology (7.

[Evaluation of lipid digestion using the 13C-mixed triglyceride breath test in patients with chronic pancreatitis].

Background: Steatorrhea represents the indirect sign of lipid maldigestion in chronic pancreatitis and even when the measurement of fecal fat is considered as a gold standard for the diagnosis of steatorrhea, this test is not commonly used within clinical practice because of the inconvenience related to sample collection. Although the use of breath test using mixted tryglicerides was initally validated as an indirect alternative for the assessment of exocrine pancreas reserve, only recently has used this method as a surrogate for the measurement of fat in feces.

Aim: To evaluate fat digestion by means of the breath test with 13C labelled mixed triglycerides in patients with chronic pancreatitis.
