A 45-year-old female with acute myelogenous leukemia (AML-M6) received an allogeneic stem cell transplantation from an HLA-identical sibling donor in June 2002. Prophylaxis against graft-versus-host disease (GVHD) consisted of cyclosporine (CsA) and short-term methotrexate. Acute GVHD did not occur and CsA was discontinued on day 145 after transplantation. However, soon thereafter she suffered from conjunctivitis, stomatitis and liver dysfunction with hypercholesterolemia and was diagnosed as having chronic GVHD. The liver dysfunction and hypercholesterolemia failed to improve despite the administration of CsA and prednisolone. Atrovastatin was not effective and immunosuppressive therapy for two months including ursodeoxycholic acid finally improved the jaundice and hypercholesterolemia. Although lipid metabolism analysis in this case disclosed the same findings as in other intrahepatic cholestatic liver diseases, the results show that the improvement of hypercholesterolemia in chronic GVHD needs the same treatment as chronic GVHD.

Temsirolimus is a targeted therapy that inhibits mammalian target of rapamycin (mTOR), a central regulator of tumor cell responses to growth stimuli. Temsirolimus has a broad anticancer activity profile that impacts tumor cell growth, proliferation, and survival through its specific inhibition of mTOR. In a randomized phase III trial that enrolled previously untreated patients with advanced renal cell carcinoma (RCC) and poor prognostic features, temsirolimus significantly prolonged overall survival compared with interferon-alpha, a standard therapy (p = 0.008). Because of the results, temsirolimus was approved by the U. S. Food and Drug Administration for treatment and is considered a first-line treatment for patients with advanced RCC with poor prognostic features. Temsirolimus is administered at a flat weekly IV dose of 25 mg given over 30-60 minutes. Gastrointestinal disorders (stomatitis, anorexia, nausea, diarrhea, and vomiting), rash, fatigue, edema, infections, and dyspnea, as well as hematologic and metabolic laboratory abnormalities occur in patients receiving temsirolimus. Metabolic side effects include hyperglycemia, hypercholesterolemia, hypertriglyceridemia, and hypophosphatemia. Most adverse reactions associated with temsirolimus can be managed medically or addressed by supportive measures. Nurses can improve patient outcomes through early recognition of side effects and prompt interventions.

The aim of this study was to evaluate the most common adverse events (AEs) linked to everolimus therapy, a mammalian target of rapamycin (mTOR) inhibitor, in children and adolescents with tuberous sclerosis complex (TSC) hospitalized in one medical center. The study group included 18 patients with a diagnosis of subependymal giant cell astrocytoma or renal angiomyolipoma related to TSC. The median duration of therapy was 15 months. All clinical symptoms and laboratory abnormalities including complete blood count, fasting lipid profile, glucose level, and liver and kidney function tests were analyzed as potential AEs. The most common AEs of everolimus therapy were laboratory abnormalities (100% of patients) and infection complications (83 episodes in 15 patients). Infectious episodes of pharyngitis (67%), diarrhea (44%), stomatitis (39%), and bronchitis (39%) were the most common infections. They were mostly mild or moderate in severity (grade 1-2). In two cases, life-threatening conditions related to mTOR inhibitor treatment were encountered. The first was classified as grade 4 pleuropneumonia and Streptococcus pneumoniae sepsis, whereas the second was classified as death related to AE (grade 5) Escherichia coli sepsis. The most common laboratory abnormalities were hypercholesterolemia (13/18 patients - 72%) and hypertriglyceridemia (12/18 patients - 66%). Neutropenia (12/18 patents - 66%) and anemia (8/18 patients - 44%) were the most common hematologic toxicities. Everolimus treatment in TSC patients may lead to life-threatening outcomes, including sepsis and death. Long-lasting effects of everolimus treatment in the context of high incidences of different laboratory abnormalities found in TSC patients are another subject that should be researched further.

The mammalian target of rapamycin (mTOR) inhibitors sirolimus and everolimus have shown their efficacy in kidney transplantation, but their wider introduction has been limited by relative high discontinuation rates. Their main advantage compared with calcineurin inhibitors (CNIs) is their relative lack of nephrotoxicity. They differ mainly in pharmacokinetic characteristics and have variable inter- and intra-individual pharmacokinetics. They are metabolized by cytochrome (CYP)-3A4/5 and CYP2C8 enzymes and are substrates for P-glycoprotein (P-gp). Their most important adverse effects are thrombocytopenia, leukopenia, hypercholesterolemia, stomatitis, diarrhea, and, although rare, interstitial pneumonitis. The narrow therapeutic window makes therapeutic drug monitoring (TDM) essential to prevent toxicity or rejection. As we discuss here, the main future challenge is to further optimize mTOR inhibitor (mTORi)-based immunosuppressive therapy.
