Filter by:This is a multicenter, double-blind, placebo-controlled, parallel-design study. The study will enroll approximately 210 adult male and female subjects with stage 3 or 4 chronic kidney disease and metabolic acidosis. The study dosing (TRC101 or placebo) will continue for 12 weeks once daily. The maximum study duration is anticipated to be up to 16 weeks.
Objective: Arterial blood gas (ABG) is essential in the clinical assessment of potential acutely ill patients venous to arterial conversion (v-TAC), a mathematical method, has recently been developed to convert peripheral venous blood gas (VBG) values to arterialized VBG (aVBG) values. The aim of this study is to test the reliability of aVBG compared to ABG in an intensive care unit (ICU) setting. Method: Consecutive patients admitted to the ICU with pH values <7,35 or >7,45 are included in this study. Paired ABG and aVBG samples are drawn from patients via arterial catheter, central venous catheter and/or peripheral venous catheter and compared.
Providing summarized information on the clinical and biochemical characteristics and types of renal tubular acidosis in children in Assiut University Childern Hospital.
Linezolid is the second line agent in the treatment of MRSA and PRSP infections, and it is also the drug of choice for VRE infections. It can be an alternative option against multidrug resistant tuberculosis and non-tuberculosis mycobacterium. However, Patients who receive more than 2 weeks of treatment duration and who have renal dysfunction or severe cirrhosis may prone to experience anemia, thrombocytopenia, and leukopenia. Long-term use may also result in lactic acidosis, peripheral neuropathy and optic neuropathy due to mitochondrial toxicity. Thus, this study will analysis the medical charts in National Taiwan University Hospital (NTUH) from 2011 to 2016 to get the population demographics who use linezolid and analysis the occurrence rate of myelosuppression, neuropathy and lactic acidosis. Simultaneously, the investigators also use therapeutic drug monitoring (TDM) to prospectively evaluate the association of linezolid blood concentration and clinical efficacy and safety. The result of this study will provide physicians more information to prevent concentration-dependent adverse effects.
To determine if intravenous thiamine would decrease the time to reversal of shock in patients with septic shock.
The aim of this study is to test if alkali treatment will preserve kidney graft function and diminish the progression of chronic kidney disease in renal transplant patients. Additionally the underlying mechanisms of nephrotoxicity of metabolic acidosis will be investigated in this cohort. This study is a multi-center, prospective, randomized, single-blind (patient), placebo-controlled interventional trial to test the superiority of alkali treatment in comparison to placebo on preservation of kidney function in 300 kidney transplant recipients. The duration of the study will be 2 years for the individual participant. The patients will be randomized into 2 arms: intervention arm (sodium hydrogen carbonate, product: Nephrotrans®) and placebo arm (placebo comparator). Several studies in CKD (chronic kidney disease) patients have shown that alkali therapy slows progression of CKD.
Objectives: Intravenous (IV) fluid administration is a fundamental component of diabetic ketoacidosis (DKA) treatment. Normal saline (NS), the most common IV fluid used in DKA management, contains more chloride than human blood. Excessive amounts of chloride have been shown to cause a detrimental metabolic acidosis. Other IV fluids have more physiologic chloride levels, such as lactated ringers (LR). This study will compare the rates of hyperchloremic metabolic acidosis in children treated with NS to those treated with LR to determine the effect on overall length of acidosis and length of stay in the hospital or intensive care unit. Design: Single-center, double blinded, randomized controlled trial. Subjects: Children aged 0 to 18 years who present with diabetic ketoacidosis and require pediatric intensive care unit admission. Patients with evidence of shock, multi-organ failure or clinically significant cerebral edema will be excluded. The projected study population will be 104 patients, 52 in each arm. Interventions: Patients will be enrolled within 1 hour of presentation to the emergency room or pediatric intensive care unit if transferred directly from another facility. They will be randomized to receive intravenous fluids containing 0.9% saline or lactated ringers. All patients will be treated using the institutional DKA protocol with the content of the intravenous fluids being the only difference in treatment between arms. Study intervention lasts until the end of the acute management of DKA. Planned measurements and study outcomes: The primary study outcome will be duration of metabolic acidosis. Resolution of metabolic acidosis will be defined in three ways: 1. Normalization of the ketosis; 2. Normalization of the serum pH; 3. Normalization of the serum bicarbonate level. Secondary outcomes will include length of stay in the pediatric intensive care unit and length of stay in the hospital. All outcomes will be correlated with the overall chloride load given via intravenous fluids during DKA management. Regression modelling will control for any baseline differences between the groups in regards to severity of DKA, and if newly diagnosed or poorly controlled diabetes mellitus.
Metabolic acidosis recovers a wide range of diseases in which an oral alkalinization could be useful. This therapeutic intervention has been said to increase extracellular volume leading to rising blood pressure. No prospective data has been published in clinical routine. Here, investigators propose to follow patients in which an oral alkalinization is indicated: blood pressure, body weight, and a clinical evaluation of the extracellular compartment will be performed at the beginning and during the follow-up of participants. The principal criterion of evaluation will be the variation in the extracellular compartment.
This is a single-center, observational study. Investigators aim to characterize the metabolism of lactate in children over the first forty-eight hours following cardiac surgery. Blood samples will be obtained up to 12 timepoints. Samples will be analyzed for concentration of pyruvate. Results will be compared to standard of care laboratory results for lactate and other direct and indirect measures of cardiac output.
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.
