S Patel, R Levin-Epstein, J Kobashigawa
BACKGROUND: The present study reports a case of piperacillin-induced thrombocytopenia in a dual heart and kidney transplant patient on January 28, 2016 (taking mycophenolate mofetil and tacrolimus). Before the transplant, the patient was treated with Zosyn twice, with no reports of thrombocytopenia or allergy. However, he was diagnosed with heparin-induced thrombocytopenia and vancomycin allergy during each of those hospitalizations, respectively. Eight months after the transplant, the patient presented with infectious symptoms and was started on Zosyn...

BACKGROUND: Infection and graft-versus-host disease (GVHD) are among the most common complications after hematopoietic stem cell transplantation (HSCT). With well-known risk factors including allogeneic HSCT and GVHD, tuberculosis (TB) has a higher incidence and shorter survival rate in HSCT recipients than in the general population. CASE REPORT: A 55-year-old Indonesian female with a history of latent TB was found to have acute myeloid leukemia 3 months after allogeneic HSCT...

Mucormycosis has emerged as a major threat to transplant recipients with high morbidity and mortality. This infection most commonly presents with rhino-sino-orbital localization. Gastrointestinal mucormycosis is uncommon, with presenting symptoms usually abdominal in nature. Here, we describe the case of a liver transplant recipient who developed gastrointestinal mucormycosis with an initial manifestation of femoral nerve palsy, ultimately resulting in fungal dissemination and patient demise. This case highlights the challenges in making a timely diagnosis of mucormycosis, particularly in immunocompromised patients...

BACKGROUND: Thrombotic microangiopathy (TMA) pathogenesis after living donor liver transplantation (LDLT) is thought to be caused by release of unusually large von Willebrand factor multimers (UL-vWFMs) resulting from sinusoidal endothelial cell damage and induction of platelet adhesion and aggregation. A decrease in a disintegrin-like and metalloproteinase with thrombospondin type 1 motifs-13 (ADAMTS-13) that cleave UL-vWFMs might cause excessive UL-vWFMs activity and result in platelet thrombus formation...

J S Kim, J W Yang, B G Han, H J Kwon, J H Kim, S O Choi
BACKGROUND: Cyclosporine (CsA) usually reduces glomerular filtration rate (GFR) but also can induce tubular injury without resulting in GFR reduction. Apelin is an endogenous ligand for the apelin receptor and has diverse physiologic roles related to hemodynamic or metabolic processes. We investigated the renoprotective role of apelin against CsA-induced tubular toxicity in rats. METHODS: Rats were given CsA (15 mg/kg/day) and/or apelin-13 (15 μg/kg/day) for 7 days via subcutaneous injection...

BACKGROUND: Individual differences in the pharmacokinetics (PK) of tacrolimus (TAC), an immunosuppressive drug, are reportedly associated with single-nucleotide polymorphisms (SNPs) of cytochrome P450 (CYP) 3A5 and multidrug resistance protein 1 (MDR1). We determined the effect of SNPs in CYP3A5 and MDR1 exons 21 and 26 on TAC PK parameters. METHODS: Thirty-eight Japanese patients who underwent renal transplantation were genotyped for CYP3A5 and exons 21 and 26 of MDR1 with the use of polymerase chain reaction-restriction fragment length polymorphism analysis...

BACKGROUND: Delayed xenograft rejection (DXR) is an insurmountable barrier for xenotransplantation. Previous studies reported that hamster hearts transplanted into rats undergo DXR and stop functioning after the cessation of immunosuppression. Herein, we investigated the effects of resveratrol on preventing DXR in a hamster-to-rat vascularized cardiac xenograft model. METHODS: Hamster hearts were engrafted into Lewis rat recipients. Recipient rats received a graft acceptance-inducing treatment of leflunomide and FK506 for 2 weeks to prevent acute xenograft rejection (AXR)...

BACKGROUND: Lung ischemia-reperfusion injury is characterized by formation of reactive oxygen species and cellular swelling leading to pulmonary edema and primary graft dysfunction. Phosphodiesterase 5 inhibitors could ameliorate lung ischemia-reperfusion injury by interfering in many molecular pathways. The aim of this work was to evaluate and compare the effects of sildenafil and tadalafil on edema and reactive oxygen species formation in an ex vivo nonhuman animal model of lung ischemia-reperfusion injury...

BACKGROUND: Geniposide (GEN) is the major ingredient of Gardenia jasminoides Ellis, which has anti-inflammatory and anti-apoptotic activities and is widely used to treat ischemia disease. Inflammation and apoptosis play an important role in hepatic ischemia/reperfusion (I/R) injury. The current study was conducted to explore the effects of geniposide on hepatic I/R injury and its potential molecular mechanism in mice. METHODS: Fifty Sprague-Dawley rats were randomly divided into 5 groups: the sham group (sham), the hepatic I/R injury group (IRI) and the GEN groups (low, middle, and high)...

BACKGROUND: Rapid cooling at procurement after cross-clamping has been the cornerstone of organ preservation. NanoICE is a new form of ice that has emerged in the food industry and is providing more efficient cooling and preservation than regular ice. We hypothesize that the use of NanoICE will accelerate the cooling process of the allograft and will be able to maintain a steady low temperature without causing any significant histologic damage. METHODS: In this randomized pilot study, 14 pigs were used to study the liver core/surface cooling in a non-survival organ procurement operation...

BACKGROUND: Endomyocardial biopsy (EMB) has been defined as the gold standard method for surveillance of rejection after heart transplantation, and it has also been used in the diagnosis of myocarditis and the unknown causes of cardiomyopathies. The procedure, however, is not free from complications. Access through the jugular vein or the femoral vein is the standard approach. In this study, we performed biopsies by using a long, curved sheath and evaluated the rate of complications with this technique...

BACKGROUND: Extracorporeal membrane oxygenation (ECMO) is being used more often as a bridge to transplantation (BTT) in patients with acutely decompensated end-stage lung disease in Korea. ECMO as a BTT may be the only rescue strategy for severe acute respiratory failure, but many centers still consider it to be a relative contraindication to lung transplantation because of its poor outcome. Because there are not enough lung donors, it is important to determine their optimal use. We reviewed and analyzed our experiences with the use of ECMO as a BTT in patients with acute respiratory failure...

BACKGROUND: Liver transplantation (LT) is thought to resolve cognitive deficit due to hepatic encephalopathy (HE). The aim of this study was to determine the factors associated with the outcomes of patients with HE after LT. METHODS: The authors reviewed the medical records of 388 patients with HE who underwent LT from 1996 to 2014. RESULTS: There were 282 patients with grade 1-2 HE and 106 patients classified as grade 3-4. Patients in the latter group had a tendency for a more decompensated hepatic condition than patients with grade 1-2 HE...

BACKGROUND: Cirrhosis caused by hepatitis C is the most common indication for liver transplantation. The most aggressive form of hepatitis C virus (HCV) relapse after liver transplantation is fibrosing cholestatic hepatitis C, which can be observed in 2% to 15% of recipients. METHODS: Double therapy with peg-interferon and ribavirin was characterized by low antiviral response, rapid fibrosis, and frequent graft failure within 1 year after surgery. RESULTS: Introduction of direct-acting antivirals for HCV treatment allows for more efficient therapy with less adverse reactions, including patients with fibrosing cholestatic hepatitis C...
