Antifungal stewardship (AFS) programmes are needed in tertiary-care hospitals. Our aim is to describe a bedside non-restrictive AFS programme, and to evaluate its economic impact. During the first year of the AFS a bundle of non-interventional measures were implemented. During the second year an infectious diseases specialist visited 453 patients receiving candins, liposomal amphotericin B, voriconazole or posaconazole. Monthly costs were studied with an interrupted time series (ITS) analysis. The main prescribing departments were haematology (35%), medical departments (23%), and intensive care units (20%). Reasons to start antifungal therapy were: targeted therapy (36%), prophylaxis (32%), empirical therapy (20%) and pre-emptive therapy (12%). At the initial visit, diagnostic advice was provided in 40% of cases. The most common therapeutic recommendations were to de-escalate the antifungal drug (17%) or to suspend it (7%). Annual total antifungal expenditure was reduced from US$3.8 million to US$2.9 million over the first 2 years, generating net savings of US$407,663 and US$824,458 per year after considering the cost of additional staff required. The ITS analyses showed a significant economic impact after the first 12 months of the intervention (p 0.042 at month 13), which was enhanced in the following 24 months (p 0.006 at month 35). The number of defined daily doses decreased from 66.4 to 54.8 per 1000 patient-days. Incidence of candidaemia was reduced from 1.49 to 1.14 (p 0.08) and related mortality was reduced from 28% to 16% (p 0.1). A collaborative and non-compulsory AFS program based on bedside intervention is an efficacious and cost-effective approach that optimizes the use of AF drugs.

The LIS2T study was an open-label, multicenter study in which recipients of a primary liver transplant were randomized to cyclosporine microemulsion (CsA-ME) (Neoral) (n ϭ 250) (monitoring of blood concentration at 2 hours postdose) C 2 or tacrolimus (n ϭ 245) (monitoring of trough drug blood level [predose]) C 0 to compare efficacy and safety at 3 and 6 months and to evaluate patient status at 12 months. All patients received steroids with or without azathioprine. At 12 months, 85% of CsA-ME patients and 86% of tacrolimus patients survived with a functioning graft (P not significant). Efficacy was similar in deceased-and living-donor recipients. Significantly fewer hepatitis C-positive patients died or lost their graft by 12 months with CsA-ME (5/88, 6%) than with tacrolimus (14/85, 16%) (P Ͻ 0.03). Recurrence of hepatitis C virus in liver grafts was similar in each group. Based on biopsies driven by clinical events, the mean time to histological diagnosis of hepatitis C virus recurrence was significantly longer with CsA-ME (100 Ϯ 50 days) than with tacrolimus (70 Ϯ 40 days) (P Ͻ 0.05). Median serum creatinine at 12 months was 106 mol/L with CsA-ME and with tacrolimus. More patients who were nondiabetic at baseline received antihyperglycemic therapy in the tacrolimus group at 12 months (13% vs. 5%, P Ͻ 0.01). Of patients who were diabetic at baseline, more tacrolimus-treated individuals required anti-diabetic treatment at 12 months (70% vs. 49%, P ϭ 0.02). Treatment for de novo or preexisting hypertension or hyperlipidemia was similar in both groups. In conclusion, the efficacy of CsA-ME monitored by blood concentration at 2 hours postdose and tacrolimus in liver transplant patients is equivalent to 12 months, and renal function is similar. More patients required antidiabetic therapy with tacrolimus regardless of diabetic status at baseline.

Level III, retrospective comparative study.

in the routine clinical practice, a moderate deterioration of renal function is frequent after liver transplantation. However, advanced chronic kidney disease is infrequent in patients with a good pre-transplant renal function.
