[Low levels of 25-hydroxyvitamin D (25OHD) in patients with inflammatory bowel disease and its correlation with bone mineral density].

Unlabelled: Patients with inflammatory bowel disease (IBD) are at risk of having vitamin D deficiency (25-OHD) and low bone mineral density (BMD).

Objectives: To measure 25OHD in a young group of IBD patients submitted to a clinical evaluation, routine biochemistry and BMD measurement (lumbar spine and proximal femur).

Results: 39 Crohn disease (CD) and 37 ulcerative colitis (UC) patients had lower serum levels of 25OHD compared to the control group (CD p = 0.

[Correlation of Doppler ultrasound of the portal system with endoscopic changes caused by portal hypertension in cirrhotic patients].

Background: The portal hypertension in cirrhotic patients is the main cause of this illness complication, that are clinically translated to visible collateral circulation in the abdominal wall, ascites and esophageal varices.

Aim: To evaluate if the portal system echodoppler is able to estimate the presence of esophageal varices, gastric varices and congestive gastropathy in patients with hepatic cirrhosis.

Patients And Methods: One hundred and eighty six patients of the gastroenterology and hepatology ambulatory of the Clinical Hospital of the Federal University of Paraná, Curitiba, PR, Brazil, had been selected for evaluation.

[Bone mineral density evaluation in inflammatory bowel disease patients].

Background: Inflammatory bowel disease patients have shown greater reduction of the bone mineral density compared to healthy people.

Aim: To evaluate the bone mineral density in a population of patients with inflammatory bowel disease.

Methods: Ninety patients from 20 to 50 years old, of the Inflammatory Bowel Disease Ambulatory of the Gastroenterology Service of the Clinics Hospital, Curitiba, PR, Brazil, were selected for the evaluation.
