BACKGROUND: Solid-organ transplants provide a second chance to thousands of critically ill patients with end-organ failure each year. Immunosuppressants are administered to patients to prevent graft rejection of a transplanted organ, such as a heart, kidney, or liver, while placing the recipient at greater risk for infection and cancer. OBJECTIVE: The literature provides evidence of various cancers that have been found to develop in patients' posttransplantation...

Colistin is a last resort antibiotic to treat multidrug-resistant Gram-negative bacteria infections. Colistin is administered intravenously in the form of its inactive prodrug colistin methanesulfonate (CMS). For patients with acute kidney impairment and continuous renal replacement therapy high extracorporeal clearance may cause a substantial removal of active colistin from the bloodstream, eventually decreasing its antibacterial efficacy. Currently recommended doses of CMS may therefore be inadequate for these patients...

The interleukin-1 family is an important component of the innate immune system and plays an important role in regulating immune responses on the invasion of intracellular parasites in the acquired immune system. Interleukin 1β (IL-1β) is one of the members of the IL-1 family that predominantly activates downstream signaling pathways to play immunological functions of stimulating T and B lymphocyte activation and promoting the various syntheses of inflammatory substances in conjunction with other cytokines...

Within the last two decades, several high-impact viruses have emerged in the global swine population, including porcine reproductive and respiratory syndrome virus (PRRSV). In Uruguay, the more recent serological survey for PRRSV and other notifiable diseases such as Aujeszky's disease virus (ADV) and classical swine fever virus (CSFV) dated from year 2000. The main purpose of this study was to update our information on the infection status of PRRSV, ADV and CSFV in Uruguayan pig herds, in order to keep informed about the epidemiological situation of these notifiable infections in the country...

Complement factor I (CFI) is a novel regulatory serine protease that plays an important role in resistance to pathogen infection. In this study, the CFI gene of Pelteobagrus vachellii (Pv-CFI) was sequenced and characterized. The full-length cDNA of 2320 bp includes a 155 bp 5'-untranslated region (UTR), a 164 bp 3'-UTR, and a 2001 bp open reading frame (ORF) encoding a 667 amino acids. Multiple sequence alignment revealed five highly conserved domains with a typical modular architecture and identical active sites in vertebrates, indicating a conserved function...

Hepatitis C virus (HCV) infection affects many organs in the body, including the liver, kidneys, skin, joints and others. Although the hepatic manifestation of HCV has been widely studied, the extrahepatic manifestaions of HCV have not been fully appreciated. Studies have shown that patients with HCV have a higher risk of chronic kidney disease and end-stage renal disease, as well as poorer outcomes after kidney transplantation. Given these findings, it is important to screen HCV patients for presence of renal impairement in a timely manner...

REVIEW

Hepatitis C virus infection (HCV) is a common comorbidity in patients who have undergone kidney transplantation and is associated with increased morbidity and mortality compared with recipients who do not have chronic HCV infection. Because interferon-α-based therapies can precipitate acute rejection, they are relatively contraindicated after kidney transplantation. Thus, the majority of kidney transplant recipients with HCV remain untreated. There are now all-oral, interferon-free direct-acting antiviral therapies for HCV infection that are extremely effective and well tolerated in the general population...

BACKGROUND: Shunt nephritis is a rare, reversible immune-complex mediated complication of CSF shunt infection that can progress to end-stage renal disease and even death if diagnosis is delayed. CASE DESCRIPTION: The present case report details the manifestation and clinical course of shunt nephritis in a 50-year old patient who presented with symptoms of nephrotic syndrome 30 years after ventriculo-jugular shunt placement. Diagnosis was delayed due to initial negative CSF and blood cultures but later a CSF culture was positive for Propionibacterium acnes...

Interferon (IFN)-stimulated gene 15 (ISG15) encodes a ubiquitin-like protein that is heavily involved in immune response elicitation. As an important member of interferon regulatory factor (IRF) family, IRF1 can activate the expression of multiple genes, including the human optineurin gene (Sudhakar et al., 2013). In this study, a sequence in the promoter region of the optineurin gene was compared to the 5' flanking region of the porcine isg15 gene. Porcine IRF1 also possesses antiviral activity against several swine viruses (Li et al...

Hepatitis C (HCV) remains the single most common etiology of end-stage liver disease leading to simultaneous liver/kidney transplant (SLKT) and has worse post transplant survival compared to non-HCV patients. We aim to assess the effectiveness and tolerance of the all-oral direct acting antiviral (DAA) agents with or without ribavirin (RBV) in the treatment of HCV recurrence post SLKT. 34 patients were studied retrospectively, composed predominantly of treatment-naïve (73.5%) non-Caucasian (61.8%) males (82...

JC polyomavirus (JCPyV) was identified in 1971 in the brain tissue of a patient (J.C.) affected by the progressive multifocal leukoencephalopathy (PML). JCPyV encodes for the oncoproteins large T antigen (Tag) and small t-antigen (tag). These oncoproteins are responsible of the cell transformation and tumorigenesis in experimental animals. JCPyV is ubiquitous in human populations. After the primary infection, which is usually asymptomatic, JCPyV remains lifelong in the host in a latent phase. Its reactivation may occur in heathy subjects and immunocompromised patients...

Rituximab (RTX) is becoming a standard treatment for patients with anti-neutrophil cytoplasmic antibodies (ANCA)-associated vasculitis (AAV) but heterogeneity exists regarding its use. We present our uncontrolled experience with RTX in patients with refractory AAV and also the results of a systematic review of non-randomized studies on RTX in AAV patients. We retrospectively reviewed the records of AAV patients treated with RTX following an inadequate response to immunosuppressives between 2011 and 2015. The systematic review covered all English articles listed in PubMed until June 2017...

Investigations of anti-HIV-1 human hematopoietic stem/progenitor cell (HSPC)-based gene therapy have been performed by HIV-1 challenge after the engraftment of gene-modified HSPCs in humanized mouse models. However, the clinical application of gene therapy is to treat HIV-1-infected patients. Here, we developed a new method to investigate an anti-HIV-1 HSPC-based gene therapy in humanized mice previously infected with HIV-1. First, humanized mice were infected with HIV-1. When plasma viremia reached >107 copies/mL 3 weeks after HIV-1 infection, the mice were myeloablated with busulfan and transplanted with anti-HIV-1 gene-modified CD34+ HSPCs transduced with a lentiviral vector expressing two short hairpin RNAs (shRNAs) against CCR5 and HIV-1 long terminal repeat (LTR), along with human thymus tissue under the kidney capsule...

The human JC polyomavirus (JCPyV) infects the majority of the population worldwide and presents as an asymptomatic, persistent infection in the kidney. In individuals who are immunocompromised, JCPyV can become reactivated and cause a lytic infection in the central nervous system resulting in the fatal, demyelinating disease progressive multifocal leukoencephalopathy (PML). Infection is initiated by interactions between the capsid protein viral protein 1 (VP1) and the α2,6-linked sialic acid on LSTc, while JCPyV internalization is facilitated by 5-hydroxytryptamine 2 receptors (5-HT2Rs)...
