NCT ID: NCT05143879 Completed - Athletes Clinical Trials

Long-Term Effect of Combined Citrulline and Nitrate-Rich Beetroot Extract Supplementation

Start date: May 1, 2018
Phase: N/A
Study type: Interventional

Citrulline (CIT) and nitrate-rich beetroot extract (BEET) are widely studied ergogenic aids. However, both supplements have been studied in sort-term and isolated. To the best of the authors' knowledge, the effects of combining both supplements on exercise-induced muscle damage (EIMD) and hormone status have not been investigated to date. Therefore, the main purpose of this study was to determine the effect and degree of potentiation of the long-term (9 weeks) mixture of 3 g/day of CIT plus 2.1 g/day of BEET (300 mg/day of NIT) supplementation on EIMD markers (urea, creatinine, AST, ALT, GGT, LDH and CK) and anabolic/catabolic hormone status (testosterone, cortisol and Testosterone cortisol ratio (T/C)) in male trained triathletes. This study was a double-blind, placebo-controlled trial where participants (n = 32) were randomized into 4 different groups: placebo group (PLG; n = 8), CIT group (CITG; 3 g/day of CIT; n = 8), BEET group (BEETG; 2.1 g/day of BEET (300 mg/day of NIT) ; n = 8) and CIT-NIT group (CIT-BEETG; 3 g/day of CIT plus 2.1 g/day of BEET (300 mg/day of NIT); n = 8). Blood samples were collected from all participants at baseline (T1) and after 9 weeks of supplementation (T2).

NCT ID: NCT02520440 Completed - Clinical trials for Organ Failure, Multiple

INtestinal Failure, multiPle Organ Failure ANd CItrulline Assessment

IN-PANCIA
Start date: September 2014
Phase: N/A
Study type: Observational

The gastrointestinal dysfunction occurs frequently during the intensive care unit (ICU) stay and is associated with a worse prognosis. The gastrointestinal failure (GIF) is diagnosed based on symptoms such as bowel distension, ileus, diarrhea, digestive bleeding, or intestinal ischemia. A GIF score based on has been demonstrated to be correlated with outcome, with higher scores indicating higher risk of death. However, GIF may be occult or clinical signs can go undetected in critically ill patients due to the frequent use of analgesic, sedative or neuromuscular blocking agents, acute neurologic diseases, or delirium. Citrulline is a potential biomarker for small bowel function in critically ill patients with maintained renal function. Normal plasma citrulline levels (12-55 µmol/L) are determined by the balance between gut synthesis and kidney degradation. GIF is involved in the pathogenesis of multiple organ dysfunctions and failures (MOF) through various mechanisms, and it is often associated with high intra-abdominal pressure (IAP). IAP greater than 12 mmHg, may lead to abdominal compartment syndrome (ACS) and MOF, including cardiac, respiratory and kidney failure. Studies have suggested that GIF can be the consequence rather than the cause of MOF. The aim of this study is to investigate if plasma citrulline levels is associated with a clinical diagnosis of GIF, and may predict the development of MOF.
