Although posaconazole is approved for the prophylaxes and treatment of invasive fungal infections, specific dosing guidelines for posaconazole in (morbidly) obese patients are not specified. There is clear evidence indicating that heavier patients are receiving a sub-optimal dose if the current guidelines are used. Specifically in the setting of augmented prevalence of species with intermediate susceptible to posaconazole, adequate dosing is needed at start of treatment.
Therefore it seems prudent to conduct a trial in a cohort of obese patients who receive posaconazole (300mg or 400mg) and define the pharmacokinetics. These will then be compared to the pharmacokinetics in a normal-weight group receiving 300mg posaconazole.
Obese patients with a BMI ≥ 35 kg/m2 undergoing endoscopic gastric bypass surgery will receive a 300 mg or 400mg dose of posaconazole. A PK curve will be determined after administration at t=0.45, 0.75, 1, 1.5, 2, 4, 8, 12, 24, and (if feasible) 48 hours post infusion. Blood samples (4 mL) on PK days will be taken to obtain at least 2.0 mL of plasma.

Total or subtotal destruction of the pituitary gland by chemical injection. It is usually achieved by injection of ethyl alcohol via trans-sphenoidal cannulation under stereotaxic control. It is usually performed for the treatment of intractable pain.
Hemorrhagic necrosis that was first demonstrated in rabbits with a two-step reaction, an initial local (intradermal) or general (intravenous) injection of a priming endotoxin (ENDOTOXINS) followed by a second intravenous endotoxin injection (provoking agent) 24 h later. The acute inflammation damages the small blood vessels. The following intravascular coagulation leads to capillary and venous THROMBOSIS and NECROSIS. Shwartzman phenomenon can also occur in other species with a single injection of a provoking agent, and during infections or pregnancy. Its susceptibility depends on the status of IMMUNE SYSTEM, coagulation, FIBRINOLYSIS, and blood flow.
The analysis of a chemical substance by inserting a sample into a carrier stream of reagent using a sample injection valve that propels the sample downstream where mixing occurs in a coiled tube, then passes into a flow-through detector and a recorder or other data handling device.
Intradermal injection of a heated (pasteurized) saline suspension of sarcoid tissue obtained from a sarcoid spleen or lymph node. In patients with active sarcoidosis a dusky red nodule develops slowly over the next few weeks at the injection site. Histologic examination, an essential part of the complete test, reveals sarcoid tissue.
