Article Synopsis
- Acute intermittent porphyria is a rare disorder caused by issues in heme production, leading to elevated levels of certain precursors in the blood and urine.
- Patients experience severe symptoms including abdominal pain, vomiting, neurological issues, and psychological disturbances during attacks.
- Treatment usually involves hemin infusion to help regulate heme levels; a case report shows a 78-year-old man with renal failure found relief from his porphyria symptoms through peritoneal dialysis.
Introduction: The aim of this study was to establish reference intervals for plasma cystatin C and creatinine in adults using the Gentians cystatin C method traceable to the international calibrator standard ERM-DA471/IFCC and a creatinine method traceable to the IDMS (Isotope Dilution Mass Spectrometry) creatinine reference method.
Methods: Blood samples were collected from 304 healthy blood donors (152 men and 152 women between 17 and 66 years old) with 30-31 men and 30-31 women in each ten-year interval. Plasma cystatin C was analyzed using the Gentian Cystatin C assay on a Roche cobas c702 analyzer, and plasma creatinine was analyzed using the CREA Plus assay on the Roche Modular P analyzer.

Background: Programs for population screening of colorectal cancer (CRC) have been implemented in several countries with fecal immunochemical testing (FIT) as the preferred platform. However, the major obstacle for a feces-based testing method is the limited compliance that reduces the clinical sensitivity for detection of participants with non-symptomatic CRC. Therefore, research approaches have been initiated to develop screening concepts based on biomarkers in blood.

This study evaluated the effect of 4 levels of dietary nitrate addition on enteric methane production, hydrogen emission, feed intake, rumen fermentation, nutrient digestibility, microbial protein synthesis, and blood methemoglobin. In a 4×4 Latin square design 4 lactating Danish Holstein dairy cows fitted with rumen, duodenal, and ileal cannulas were assigned to 4 calcium ammonium nitrate addition levels: control, low, medium, and high [0, 5.

Methods: HA was measured by a particle-enhanced turbidimetric immunoassay (PETIA) and enzyme-linked immunosorbent assay (ELISA) in a 40-sample dilution series and 39 intensive care unit (ICU) patients.
