Active clinical trials for "Acidosis"

Metabolism is controlled by macro- and micronutrients. Protein-rich diets should lead to latent acidosis at tissue level with further negative implications. Food supplements with alkaline salts are available and popular pretending to prevent these changes. Within a randomized double-blind placebo-controlled trial, the investigators tested the hypotheses 1) that a 4-week protein-rich diet induces a latent tissue acidosis and 2) an alkaline supplement can compensate this. Acid-base balance and important metabolic parameters were determined before and after 4 weeks of supplementation by peripheral blood samples, indirect calorimetry and muscle microdialysis before and after a protein-rich test meal.

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.

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.

This study will compare hemodialysis treatment with a standard, high-bicarbonate dialysis bath versus a lower bicarbonate dialysis bath, and will compare intradialytic acid-base changes and overall control of metabolic acidosis with the 2 treatment regimens.

This study will compare acid-base changes during hemodialysis treatments with a standard dialysis bath versus a lower bicarbonate dialysis bath, and aims to define the factors that limit equilibration of the bicarbonate concentration in a patient's blood with that in the dialysate.

This prospective study includes 5 patients with ARDS (Acute Respiratory Distress Syndrome) treated by mechanical ventilation. In case of respiratory acidosis, extracorporeal CO2 (carbon dioxide)removal might be necessary. We hereby work with the Abylcap system with the oxygenator Lilliput2 as CO2 remover (Bellco, Italy). The patients (M/V) are older than 18, not pregnant, have a BMI<30, and no contraindication for anticoagulation therapy. Under standard conditions patients are treated with a blood flow of QB=300mL/min and a gas flow (100% 02) of QG=7L/min. Blood sampling is performed from the arterial bloodline in the patients at 0, 1h, 3h, 24h, 48h, 72h, 96h, and 120h. A parameter study is also performed to optimise CO2 removal. Herewith, blood samples (1mL) are taken from the inlet and outlet line of the Lilliput2 at the previously mentioned time points and for different flow setting: Blood flow (QB) 200-300-400mL/min and gas flow (QG) 1.5, 3, 6, 7, 8L/min Blood samples are analysed for the different blood gases from which the extraction in the CO2 remover can be calculated for each setting of QB (blood flow) and QG (gas flow).

The study will evaluate the impact of high velocity therapy (HVT) on reduction of work of breathing (as implied by breath frequency) and enhanced blood lactate decline during recovery from a Wingate-type Exercise test. The study will include four study segments, corresponding to four different therapy settings.

To determine if co-administration of subcutaneous (SQ)Insulin glargine in combination with intravenous (IV) insulin decreases the time to resolution of ketoacidosis and requirement for ICU admission compared to IV insulin with delayed administration of SQ glargine for the treatment of diabetic ketoacidosis (DKA).

To determine if intravenous thiamine would decrease the time to reversal of shock in patients with septic shock.

This study is a pilot study taking place in Moshi, Tanzania at the Kilimanjaro Christian Medical Centre (KCMC). The study aims to introduce fetal scalp stimulation into the intermittent auscultation protocols at KCMC, and to validate whether or not a handheld Doppler device can perform the fetal scalp stimulation test accurately.
