Cryptococcus neoformans isolates from transplant recipients are not selected for resistance to calcineurin inhibitors by current immunosuppressive regimens.

چکیده
The immunosuppressants tacrolimus (FK506) and cyclosporine A inhibit calcineurin and have potent antifungal activity. In this study, 24% of Cryptococcus neoformans isolates from solid-organ transplant patients exhibited altered sensitivity to these drugs, which may have an impact on the infectious course but does not appear to be the consequence of immunosuppressive therapy.

Calcineurin inhibitor agents interact synergistically with antifungal agents in vitro against Cryptococcus neoformans isolates: correlation with outcome in solid organ transplant recipients with cryptococcosis.
Synergistic interactions were observed between CIs and antifungal agents against 53 (90%) of 59 Cryptococcus neoformans isolates from solid organ transplant recipients with cryptococcosis and may account for better outcomes in patients with cryptococcosis receiving these immunosuppressive agents.
متن کاملCryptococcus neoformans in organ transplant recipients: impact of calcineurin-inhibitor agents on mortality.
Variables influencing the risk of dissemination and outcome of Cryptococcus neoformans infection were assessed in 111 organ transplant recipients with cryptococcosis in a prospective, multicenter, international study. Sixty-one percent (68/111) of the patients had disseminated infection. The risk of disseminated cryptococcosis was significantly higher for liver transplant recipients (adjusted h...
متن کاملImmunotherapy with tacrolimus (FK506) does not select for resistance to calcineurin inhibitors in Candida albicans isolates from liver transplant patients.
In Candida albicans, calcineurin mediates tolerance to azole antifungal drugs, survival in serum, and virulence. In this study, we examined 24 Candida isolates from liver transplant recipients receiving a calcineurin inhibitor as a component of their immunosuppressive therapy. We were unable to detect a difference in susceptibility to calcineurin inhibitors in combination with fluconazole, seru...

PURPOSE Significantly increasing heart transplantations have been performed in Taiwan in the past decades, but the trends of maintenance immunosuppression for heart transplant recipients have not been well known. In this study, we aimed to explore the trends of maintenance immunosuppressive therapy and common complications for heart transplant recipients. METHODS We retrospectively analyzed a...
متن کاملCryptococcus neoformans infection in organ transplant recipients: variables influencing clinical characteristics and outcome.
Unique clinical characteristics and other variables influencing the outcome of Cryptococcus neoformans infection in organ transplant recipients have not been well defined. From a review of published reports, we found that C. neoformans infection was documented in 2.8% of organ transplant recipients (overall death rate 42%). The type of primary immunosuppressive agent used in transplantation inf...
