Pulmonary Nocardiosis in a Kidney Transplant Recipient: A Case Report and Review of the Literature

Yaich S, Charfeddine K, Zaghdane S, El Aoud N, Masmoudi M, Kharrat M and Hachicha J

Nocardiosis is a life threatening disease in solid organ transplant recipients. It is an uncommon but important infection for these patients. We report a case of 37- year-old kidney recipient who developed pulmonary nocardiosis that was successfully treated with intravenous imipenem and tetracyclines in conjunction with a reduction in immunosuppressive therapy. Four years later, graft function remains stable with complete regression of radiological abnormalities and absence of relapses. This case emphasizes the role of new potent immunosuppressants and diabetes in the occurrence of opportunistic infections. Nocardiosis should be suspected in the presence of pulmonary symptoms with unusual radiological presentation.

Salvage Liver Transplantation for HCC: An Old Story without Consensus?

Gonzalo Sapisochin and Ramón Charco

Hepatocellular carcinoma (HCC), the most common liver tumor is a leading cause of mortality, accounting for more than 1 million deaths annually. Most HCC are diagnosed in association with liver cirrhosis, with the main risk factors being hepatitis B and C and alcohol abuse. In the past, HCC was diagnosed at advanced stages; no treatment could be applied and the prognosis was poor. Fortunately, as a result of screening programs in high-risk populations, patients with HCC are now diagnosed at an early stage, and up to 30% can be considered for a curative treatment. These curative treatments include liver resection (LR), liver transplantation (LT) and percutaneous ablation [1]. LT is the most effective treatment for patients with HCC since it removes the tumor and surrounding cirrhotic tissue, the main risk factor for the development of new tumors. Following the Milan criteria (single tumors = 5 cm or 3 tumors all of them = 3 cm), up to 75% 4-year survival has been described with a low recurrence rate (<10%) constituting the most extended criteria for LT for HCC [2]. Some groups have developed expanded criteria for LT for HCC such as the UCSF criteria and the up-to-seven criteria, with acceptable results.
