Tacrolimus is a widely used macrolide immunosuppressant in transplant surgery, with mild and major neurologic side effects. A 21-year-old woman had undergone preemptive transplantation of a kidney from her mother. On the 1st postoperative day, the patient had headache, nausea, vomiting, and agitation. Magnetic resonance imaging (MRI) of the brain showed hyperintensity and a lesion in the right mesial temporal lobe. After we switched from tacrolimus to cyclosporine, the symptoms regressed. Persistence of the lesion, confirmed by repeated MRI, required that the patient be operated on...

Renal transplant recipients infected with hepatitis C virus (HCV) have a high risk of progressing to cirrhosis, end-stage liver diseases, and hepatocellular carcinoma. It is also considered as an independent risk for graft loss and is correlated with proteinuria, transplant glomerulopathy, HCV-associated glomerulonephritis, and chronic rejection. Previous therapy involving interferon alfa and ribavirin led to treatment complications, including toxicity, anemia, sepsis, and drug-drug interactions with calcineurin inhibitors, as well as reduced tolerability and efficacy...

Primary focal segmental glomerulosclerosis (FSGS) recurs in 30% of patients receiving their first kidney transplant and often leads to graft loss. In the past, patients with FSGS and overt nephrotic syndrome rarely underwent transplantation. Rituximab (RTX), an anti-CD20-specific monoclonal antibody, was previously reported to be a valuable option in treating relapsing FSGS after kidney transplantation. We report here the first successful kidney transplantation in a young patient with primary FSGS and massive nephrotic syndrome treated with RTX induction...

BACKGROUND: Renal transplantation has been established as the treatment of choice for end-stage renal disease (ESRD) due to diabetic nephropathy. This study aimed to investigate the risk factors for recurrence of diabetic nephropathy (RDN) in renal allografts. METHODS: We studied 1,011 renal transplant patients from 1986 to 2003, of which 95 had ESRD due to diabetic nephropathy. We retrospectively analyzed the clinical characteristics and outcomes of RDN after renal transplantation...

BACKGROUND: Maintenance therapy with oral corticosteroid (OCS) is used, although not based on evidence, for patients with severe asthma, but OCS is associated with serious adverse effects; therefore, management strategies aimed at steroid sparing are important. OBJECTIVE: To provide an update on the evidence for OCS-sparing strategies in adults with severe asthma. METHODS: A systematic literature review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines...

BACKGROUND AND PURPOSE: H2 S protects myocardium against ischaemia-reperfusion injury. This protection may involve the cytosolic reperfusion injury salvage kinase (RISK) pathway, but direct effects on mitochondrial function are possible. Here, we investigated the potential cardioprotective effect of mitochondria-specific H2 S donor, AP39, at reperfusion against ischaemia/reperfusion injury. EXPERIMENTAL APPROACH: Anaesthetised rats underwent myocardial (30 min ischaemia/120 min reperfusion) with randomisation to receive interventions prior to reperfusion: vehicle, AP39 (0...

Myocardial apoptosis is a significant problem underlying ischemic heart disease. We previously reported significantly elevated expression of cytoplasmic Omi/HtrA2, triggers cardiomyocytes apoptosis. However, whether increased Omi/HtrA2 within mitochondria itself influences myocardial survival in vivo is unknown. We aim to observe the effects of mitochondria-specific, not cytoplasmic, Omi/HtrA2 on myocardial apoptosis and cardiac function. Transgenic mice overexpressing cardiac-specific mitochondrial Omi/HtrA2 were generated and they had increased myocardial apoptosis, decreased systolic and diastolic function, and decreased left ventricular remodeling...

Mitochondrial permeability transition pore (mPTP) opening allows free movement of ions and small molecules leading to mitochondrial membrane depolarization and ATP depletion that triggers cell death. A multi-protein complex of the mitochondrial ATP synthase has an essential role in mPTP. However, the molecular identity of the central 'pore' part of mPTP complex is not known. A highly purified fraction of mammalian mitochondria containing C-subunit of ATPase (C-subunit), calcium, inorganic polyphosphate (polyP) and polyhydroxybutyrate (PHB) forms ion channels with properties that resemble the native mPTP...

Jin Xu, Erin G Brooks
Giant cell myocarditis (GCM) is a rapidly progressive and frequently fatal disease that mainly affects young to middle-aged previously healthy individuals. Early diagnosis is critical, as recent studies have shown that rapidly instituted cyclosporine-based immunosuppression can reduce inflammation and improve transplant-free survival. Before the 1980s, GCM was mainly a diagnosis made at autopsy. Owing to advancements in diagnostic and therapeutic options, it is now increasingly diagnosed on the basis of endomyocardial biopsies, explanted hearts, or apical wedge sections removed at the time of ventricular assist device placement...

Many antihypertensive agents have been demonstrated to assist in preservation of kidney function, among them those that modulate calcium channels. Calcium channel blockers may also be of value in protecting hemodialysis patients from complications of sepsis. In diabetic recipients of kidney transplant allografts treated with cyclosporine, calcium channel blockade has been retrospectively linked to improved graft preservation and to fewer episodes of sepsis. This brief review outlines clinical and experimental publications on potential protection from sepsis by addition of calcium channel blockers to standard antibiotic therapy in individuals who may or may not have normal kidney function, or in the presence or absence of immunosuppression...

BACKGROUND: The presence of clinically significant inflammation has been confirmed in the tears of 40%-65% of patients with symptoms of dry eye. Ocular surface inflammation may lead to tear film instability, epithelial cell irregularities, and permeability, resulting in chronic symptomatic pain and fluctuating vision as well as negative surgical outcomes. PATIENTS AND METHODS: A retrospective single center medical chart review of 100 patients was conducted. All patients were tested with the InflammaDry test to determine if patients exhibited elevated levels of matrix metalloproteinase 9 (MMP-9)...

Cyclosporine A (CsA), an immunomodulatory drug, and is increasingly used to treat moderate dry eye syndrome and ocular surface inflammation. However, any inhibitory effect on differentiation of fibroblasts to myofibroblasts remains unclear. Here, we show that the inhibitory effect of CsA on transforming growth factor-beta2 (TGF-β2)-induced myofibroblasts in primary cultured human pterygium fibroblasts. CsA significantly decreased mRNA and protein expression of myofibroblast-related markers including α-SMA, laminin, and fibronectin...

Environmental samples are excellent sources of natural products that possess numerous kinds of therapeutic activities. One important family of natural products is the nonribosomal peptides, which includes penicillin, cyclosporin, viomycin and daptomycin (Cubicin). These peptides are made in bacteria or fungi by large enzymes called nonribosomal peptide synthetases (NRPS). NRPSs are true macromolecular machines or nanofactories, with modular assembly-line logic, a complex catalytic cycle, moving parts and many active sites...

Although methotrexate (MTX) is mainly transported by reduced folate carrier, P-gp and MRP1 may also be involved in its transport. In our previous study, a potent P-gp and MRP1 modulator, Cyclosporine A, potentiated MTX concentration in rat brain. Since it is important for MTX therapy for brain tumor to clarify which transporter is dominant, we herein determined whether the specific P-gp substrate, rhodamine123 (Rho123), potentiates the transport and retention of MTX in the brain. Rho123 was injected intravenously or intrathecally into rats immediately after injection of MTX...

Cyclophilin D (CyPD), a mitochondrial matrix protein, has been widely studied for its role in mitochondrial-mediated cell death. Unexpectedly, we previously discovered that overexpression of CyPD in a stable cell line, increased mitochondrial membrane potentials and enhanced cell survival under conditions of oxidative stress. Here, we investigated the underlying mechanisms responsible for these findings. Spectrophotometric measurements in isolated mitochondria revealed that overexpression of CyPD in HEK293 cells increased respiratory chain activity, but only for Complex III (CIII)...

Generalized pustular psoriasis appears as an uncommon variant form of psoriasis consisting of widespread pustules on an erythematous background (von Zumbusch). A 39-year-old male patient with a history of plaque psoriasis since the age of 9 who had an acute relapse of generalized pustular psoriasis 12 days following a successful renal transplantation is presented. Despite administered immunosuppression for transplantation, the addition of cyclosporine and methotrexate did not reverse the ongoing process of disease and the patient died on the 57th posttransplant day due to multiorgan failure subsequent to severe bone marrow suppression...

Pure red cell aplasia (PRCA) is a syndrome defined by a normocytic normochromic anemia with severe reticulocytopenia and marked reduction or absence of erythroid precursors from the bone marrow. Diamond-Blackfan anemia is a congenital form of PRCA. Acquired PRCA may be either a primary disorder or secondary to some other disorder or agent. Primary acquired PRCA is an autoimmune disorder that is frequently antibody-mediated. Myelodysplastic syndromes may also present with the morphologic appearance of PRCA. Secondary acquired PRCA may be associated with collagen vascular/autoimmune disorders such as systemic lupus erythematosus; lymphoproliferative disorders such as chronic lymphocytic leukemia or large granular lymphocyte leukemia; infections, particularly B19 parvovirus; thymoma and other solid tumors; or a variety of other disorders, drugs, or toxic agents...

INTRODUCTION: Vernal keratoconjunctivis (VKC) is a severe form of pediatric ocular allergy, characterized by acute and chronic corneoconjunctival inflammation that may lead to visual sequelae. Although topical immunosuppressive drugs such as cyclosporine are usually effective, some severe forms may be refractory and require prolonged steroid therapy. Very few papers report the use of omalizumab in VKC in the literature. In the present study, we describe our clinical experience with omalizumab in severe VKC children...
