The spectrum of autosomal dominant polycystic kidney disease in children and adolescents.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary renal disorder. It is characterized by the development of renal cysts and kidney enlargement and ultimately leads to renal failure typically in the sixth decade of life. Although most patients are asymptomatic until well into adulthood, renal cysts develop much earlier, often in utero.

Argatroban anticoagulation in patients with heparin-induced thrombocytopenia requiring renal replacement therapy.

Background: Argatroban, a direct thrombin inhibitor, is used for prophylaxis or treatment of thrombosis in heparin-induced thrombocytopenia (HIT). The recommended initial dose is 2 microg/kg/min (0.5 microg/kg/min in hepatic impairment), adjusted to achieve activated partial thromboplastin time (aPTT) values 1.

Argatroban and renal replacement therapy in patients with heparin-induced thrombocytopenia.

Background: Argatroban, a direct thrombin inhibitor, is an effective anticoagulant for patients who have heparin-induced thrombocytopenia (HIT). Anticoagulation is usually required for renal replacement therapy (RRT).

Objective: To prospectively evaluate the pharmacokinetics, pharmacodynamics, and safety of argatroban during RRT in hospitalized patients with or at risk for HIT.

A prospective comparison of three argatroban treatment regimens during hemodialysis in end-stage renal disease.

Background: We prospectively evaluated 3 treatment regimens of argatroban, a direct thrombin inhibitor, for providing adequate, safe anticoagulation in patients with end-stage renal disease (ESRD) during hemodialysis.

Methods: In this randomized, 3-way crossover study, ESRD patients underwent hemodialysis sessions of 3- or 4-hour duration using high-flux membranes and each of 3 argatroban treatment regimens (A: 250-microg/kg bolus, with an additional 250-microg/kg bolus allowed; B: 250-microg/kg bolus followed by 2-microg/kg/min infusion; C: steady-state, 2-microg/kg/min infusion initiated 4 hours before dialysis). Pharmacodynamic effects including activated clotting times (ACTs); hemodialysis efficacy including single-pool Kt/V, urea reduction ratio (URR), and circuit flow; and safety through a 3-day follow-up were monitored.
