Bacterial infections are the main cause of death within the first year after liver transplantation, and the increased incidence of multidrug-resistant gram-positive pathogens has created a major challenge in the treatment of these patients. Linezolid, the first US Food & Drug Administration-approved oxazolidinone, offers a valuable novel treatment option for serious gram-positive infections. Linezolid is relatively non-toxic but prolonged treatment with linezolid was associated with thrombocytopenia. ⋯ A subgroup analysis of patients treated for >14 days revealed no statistically significant differences when compared with patients on shorter treatment. In particular, no cases of thrombocytopenia occurred during longer treatment. In conclusion, linezolid is a safe and effective treatment for adult liver transplant patients with gram-positive infections.

Granulomatous amebic encephalitis (GAE) is a rare, nearly always fatal form of encephalitis that occurs mostly in the setting of immune compromise or chronic disease. The prevalence and clinical characteristics of this Acanthamoeba infection in hematopoietic stem cell transplant (HSCT) recipients are not well described. We present an HSCT patient in whom the diagnosis of GAE was made at autopsy. ⋯ Subacute presentation of multiple recurrent panniculitis-like subcutaneous nodules associated with eosinophilia and a history of chronic rhinitis or sinusitis warrant investigation for a possible amebic infection. Prolonged corticosteroid use and a recent exposure to unhygienic water are potential risk factors for GAE. Successful outcomes may be achieved with early intensive treatment using a combination of effective drugs.
