Active clinical trials for "Acidosis"

Children with diabetic ketoacidosis risk neurological complications such as cerebral edema with high morbidity. To prevent cerebral edema, it is essential to control correction of hypovolemia, hyperglycemia and natremia. Markers usually used in management of diabetic ketoacidosis don't always permit an optimal care. Plasma copeptin levels reflect vasopressin secretion which is high in diabetic ketoacidosis. Therefore, monitoring of plasma copeptin levels could be of interest in children with diabetic ketoacidosis and risk of sévère neurological complications.

The objective of this study is to determine whether preoperative parenteral thiamin supplementation does prevent the intra and early postoperative increase of lactate and whether this effect is related to the extent of thiamine deficiency in patients undergoing heart surgery. In addition the prevalence of major thiamin deficiency in patient undergoing heart surgery will be determined.

Lactic acidosis is a potentially life-threatening disease associated with the treatment of chronic HIV infection. Although acidosis is rare, hyperlactatemia is common and may have long term consequences yet to be recognized. Lactic acidosis is a manifestation of mitochondrial toxicity; consequences which have yet to be fully recognized and understood. In this study, we propose to look at lactate clearance and production by two methods, in four treatment groups, including HIV positive subjects on highly active antiretroviral therapy (HAART) treatment regimes and without HAART regimes, with liver steatosis and without, and compared with HIV negative controls. Supplementation with cofactors thiamine, niacin and L-carnitine, which may have a positive effect on lactate metabolism by facilitating mitochondrial function, will be studied as well.

Purpose: This study investigates the effects of dietary zeolite + dolomite on performance, exercise-induced acidosis, oxidative stress, inflammation and intestinal barrier dysfunction in trained people. Hypotheses (H1): Zeolite + dolomite increase performance in an ergometer step test Zeolite + dolomite reduce exercise-induced acidosis Zeolite + dolomite reduce oxidative stress Zeolite + dolomite reduce inflammation Zeolite + dolomite improve intestinal barrier dysfunction

Whole-body periodic acceleration (WBPA) is a new, non-invasive, and promising therapy for a diverse and growing list of disorders including cardiovascular disease 6. During WBPA, patients lie in the supine position on a bed that is capable of translating back and forth parallel to the ground, along the head-to-foot axis of the patient. Thus, this treatment is best described as a form of "passive exercise." The frequency of the translation (up to 180 cycles/minute; cpm) as well as the distance traveled (2-24mm) by the bed can be adjusted by the patient or health care professional. The science behind the therapeutic effects of WBPA still remains largely unknown. The objective of this study is to determine if WBPA may be used as an effective way to reduce lactic acid concentrations during recovery after intense exercise more rapidly than previously established methods.

The study aimed to examine the effects of an alkalinisation of a NaCl (sodium chloride, salt)-rich diet on acid base status, bone metabolism, protein turnover and other influenced physiological systems. Due to increased urinary calcium excretion and bone resorption a high NaCl-intake is considered as a risk factor for osteoporosis. On the contrary an alkaline diet is known to have a beneficial influence on bone metabolism. Therefore the investigators hypothesized that an alkaline diet can reduce NaCl-induced bone resorption. 8 healthy male volunteers took part in a stationary study carried out in the metabolic ward of the German Aerospace Center. The study consisted of 2 campaigns, each lasting 16 days. Both campaigns were divided into 5 days of adaptation, 10 days of intervention and 1.5 days of stationary recovery. During the intervention period the volunteers diet was NaCl-rich (7.7 mmol Na/kg body weight/day) and supplemented in one campaign by 90 mmol potassium bicarbonate (KHCO3) in a randomized cross-over design. The other campaign served as control. Bone metabolism was studied by bone formation markers in the fasting morning blood and 24h-urinary bone resorption markers. Acid base status was assessed by blood gas analyses in the fasted and the postprandial state as well as urinary markers. Protein turnover was studied with stable isotopes. Further physiological systems like energy metabolism and the cardiovascular system are also under investigation.

This is a phase II trial in individuals who have been diagnosed with type 1 diabetes within the previous 12 months and suffered from diabetic ketoacidosis at onset of disease. The purpose of this study is to determine whether allogeneic umbilical cord mesenchymal stem cell transplantation is effective in the treatment of patients with severe type 1 diabetes.

Effect of oral sodium bicarbonate therapy on renal tubular acidosis in epilepsy patients taking topiramate.

This study involved the medical record review of resuscitation records for all severely-injured trauma patients requiring emergent surgical intervention and significant acidosis from 2005 through 2009.
