Randomized trial of tacrolimus monotherapy: tacrolimus in combination, tacrolimus alone compared (the TICTAC trial).

Background: Prior retrospective studies have suggested that tacrolimus monotherapy is an option associated with excellent outcomes and reduced toxicities.

Method: We conducted a prospective, randomized, 2-center study of tacrolimus combination therapy vs monotherapy. From April 16, 2004, to September 15, 2005, 58 adult heart transplant patients were studied.

Is toxoplasmosis prophylaxis necessary in cardiac transplantation? Long-term follow-up at two transplant centers.

Cardiac transplant recipients are often given prophylactic treatments to prevent opportunistic infections such as Pneumocystis carinii. Toxoplasmosis prophylaxis is commonly prescribed for transplant recipients who have not been exposed to this disease but receive a heart from an exposed donor. We reviewed the collective 28-year experience at two urban transplant programs with 596 patients, and found no cases of toxoplasmosis, but all patients received trimethoprim-sulfamethoxazole to prevent Pneumocystis pneumonia.

Improved survival with statins, angiotensin receptor blockers, and steroid weaning after heart transplantation.

Various immunosuppressive and adjunctive pharmacological regimens exist for cardiac transplantation, though the associations between these regimens and long-term survival are unclear. We reviewed demographic, clinical, and pharmacological data from 220 consecutive adult heart transplant recipients between 1986 and 2003 who survived beyond 3 months. Immunosuppression was cyclosporine-based (n=94) or tacrolimus-based (n=126), and 104 patients were weaned off steroids (all receiving tacrolimus).

Long-term results of tacrolimus monotherapy in cardiac transplant recipients.

Background: Conventional immunosuppression for heart transplantation is associated with various adverse effects. Tacrolimus monotherapy (TM) is an alternative strategy that minimizes exposure to additional immunosuppressants.

Methods: We retrospectively reviewed clinical data for all adult transplant recipients between January 1, 1996 and May 1, 2004.

Beta-adrenergic blockers in systemic hypertension: pharmacokinetic considerations related to the current guidelines.

Beta-adrenergic blockade has provided one of the major pharmacotherapeutic advances of the 20th century. Beta-blockers are first-line drugs for the management of systemic hypertension, used alone and in combination with other antihypertensive agents. Drugs in the beta-blocking class have the common property of blocking the binding of catecholamines to beta-adrenergic receptor sites; however, there are significant pharmacodynamic and pharmacokinetic differences between the individual agents that are of clinical importance.
