Thiopurine

Background: Thiopurine methyltransferase (TPMT) plays a significant role in the metabolism of thiopurines, and, for patients with inflammatory bowel disease (IBD), it is useful to perform TPMT genotyping prior to azathioprine (AZA) treatment. In this study, we determined TPMT gene polymorphisms in a cohort of IBD patients in Latvia. Methods: DNA samples were obtained from 244 IBD patients, and qPCR was performed for detection of rs1800462, rs1800460, and rs1142345 single-nucleotide polymorphisms (SNPs). Three common, non-functional TPMT alleles ( TPMT*2, *3B, and *3C) were identified (women, 51%; men, 49%). TPMT*2, *3A, *3B, and *3C allelic variants detected using qPCR were consistent with …

The role of body muscle mass as an indicator of activity in inflammatory bowel disease patients

Malnutrition is an objective disease activity parameter for patients with inflammatory bowel disease (IBD), particularly Crohn's Disease (CD), and is an indicator of lesion expansion or inflammatory activity. Active disease is correlated with the systemic response of the body's immune system, activating a hypermetabolic state and protein degradation (Argiles JM, 2015). These conditions lead to malnutrition, which significantly increases the risk of impaired clinical outcomes, such as delayed recovery or increased mortality (Landi F, 2019). Our aim was to identify malnutrition parameters associated with more pronounced metabolic status changes in IBD patients (i.e., classified as by low and …

One center experience of pneumatosis cystoides intestinalis

Introduction Pneumatosis cystoides intestinalis (PCI) is a rare benign condition, in which gas is found in a linear or cystic form in the subserosa or submucosa. The subserous cysts are most frequently found in the small bowel while the submucous localizations are predominantly seen in the colonic wall. Peritoneal pneumatosis, abdominal gas cysts, cystic lymphopneumatosis, intestinal emphysema or intestinal gas cysts are terms used to describe the occurrence of multiple, gas-filled cysts, of the gastrointestinal tract. Incidence of PCI was reported to be 0.03% in the general population. It is a radiographic finding and not a diagnosis, as the etiology varies from benign conditions to fulmin…
