Background: Micafungin is an echinocandin approved for the prevention of Candida spp. infection in hematopoietic stem cell transplantation and therapy of oesophageal candidiasis, disseminated candidiasis and candidemia in adults, children and neonates., Aims: To evaluate the role of micafungin for candidiasis therapy in solid organ transplant recipients., Methods: A medical literature review according to micafungin role for candidiasis therapy in transplant patients is performed., Results: Micafungin has shown fungicide activity against Candida species, including strains resistant or poorly susceptible to fluconazole. No dose adjustment is required when micafungin is administered in combination with other drugs used in transplant patients, excluding sirolimus, nifedipine and itraconazol. With these drugs, a minimal dose reduction is recommended. The results observed in transplant patients included in clinical trials are favourable and similar to results obtained in other kind of patients., Conclusions: The clinical results, its safety profile and the low grade of medical interactions permit micafungin to be considered for therapy in specific groups of transplant patients.

Anidulafungin is a new echinocandin recently approved for the treatment of esophageal candidiasis, candidemia and other forms of invasive candidiasis, such as peritonitis and intra-abdominal abscesses in non-neutropenic patients. It is fungicidal against Candida spp. and fungistatic against Aspergillus spp. It is active against Pneumocystis jirovecii. In contrast, anidulafungin does not have activity against Cryptococcus neoformans, Zygomycetes or molds, other than Aspergillus spp. The drug is well tolerated, even in patients with renal or hepatic impairment. In contrast to other echinocandins, it does not significantly interfere with the cytochrome P450 pathway and has a low drug-drug interaction profile, including calcineurinic agents and other drugs used in transplant recipients. So far, anidulafungin appears to have an excellent safety profile with few adverse events and it promises a special consideration in the management of fungal infections happening in transplant recipients.
