PP65 antigenemia in the diagnosis of cytomegalovirus infection in AIDS patients
Provedor de dados: 80
Autores: Capela,RC; Grassi,A; Souza,LR.
Cytomegalovirus causes significant morbidity and mortality in AIDS patients and those having undergone bone marrow or another transplant. PP65 antigenemia is based on detecting viral antigen in peripheral blood leukocytes through immunochemistry and by monitoring the infection in immunocompromised individuals. The present study aimed to set up this diagnostic technique in AIDS patients with active cytomegalovirus infection and verify its occurrence in the Botucatu region of São Paulo state, Brazil. Fifty patients, 35 men and 15 women aged from 24 to 69 years, were recruited from those attended at the Department of Tropical Diseases of Botucatu Medical School, UNESP, and divided into three groups according to CD4+ T lymphocyte counts and antiretroviral...

Cytomegalovirus (CMV) disease is a major cause of morbidity and mortality in solid organ transplantation. Disseminated toxoplasmosis after liver transplantation is a rare but fatal event. Serologic screening of the donor and the recipient is essential to prophylactic management, early diagnosis and therapeutic strategies to minimize the consequences of these infections. The aim of the present study was to determine the seroprevalence of CMV and Toxoplasma gondii (TG) in a Brazilian liver transplant waiting list (LTWL). Serological data were collected from 44 candidates on the LTWL between May 2003 and November 2004. Serological investigation of antibodies IgM and IgG against CMV (anti-CMV) and TG (anti-T. gondii) was performed using fluorometry commercial...

ABSTRACT In vitro studies on the pathogenesis of the human cytomegalovirus (HCMV) are conducted regularly using laboratory adapted strains that lose some characteristics during the adaptation process. Since HCMV is excreted from bodily fluids during infection or reactivation, this work aimed to isolate and culture HCMV from the MRC-5 human cells found in the urine, bronchoalveolar lavage, saliva, and plasma samples of pediatric patients with probable or confirmed infection. The samples were inoculated on cell cultures either for 14 days or until a cytopathic effect (CPE) of 80 % was observed. The cell lysates and supernatants were used to perform successive viral passages. Besides HCMV, the herpes simplex virus was detected from all the saliva samples....

UL146 variability among clinical isolates of Human Cytomegalovirus from Japan
Provedor de dados: 48
Autores: Aguayo,Francisco; Murayama,Tsugiya; Eizuru,Yoshito.
Human Cytomegalovirus (HCMV) is a herpesvirus associated with serious diseases in immunocompromised subjects. The region between ORF UL133 and UL151 from HCMV, named ULb' is frequently deleted in attenuated AD169 and in highly passaged laboratory strains. However, this region is conserved in low-passaged and more virulent HCMV, like the Toledo strain. The UL146 gene, which is located in the ULb' region, encodes a CXC-chemokine analogue. The diversity of UL146 gene was evaluated among fifty-six clinical isolates of HCMV from Japan. Results show that UL146 gene was successfully amplified by the polymerase chain reaction (PCR) in only 17/56 strains (30%), while the success rate for UL145/UL147 gene was 18/56 strains (32%). After DNA sequencing, the 35...

Cytomegalovirus (CMV) antigenemia is still one of the two major assays available for diagnosis and monitoring of CMV infections. A commercial rapid test recently available in Brazil for quantification of human cytomegalovirus pp65 antigenemia revealed by immunofluorescence technique was compared with the original in-house method revealed by immunoperoxidase in patients receiving solid organ transplants. Of 80 blood samples tested for CMV antigenemia, 34 (42.5%) were positive: commercial assay detected 33 (97%) and in-house assay detected 20 (58.8%) samples. The numbers of positive cells in the two assays were different, with a median of 4.5 and 12 positive cells obtained by in-house and commercial kit, respectively. Discrepancies between assays occurred in...

Provedor de dados: 55
Autores: Majumder,Shounak; Mandal,Sanjay K.; Bandyopadhyay,Dipanjan; Chowdhury,Subhasis Roy; Chakraborty,Partha P.; K.,Mitra.
Cytomegalovirus (CMV) infection is a relatively late complication of AIDS. Like other viruses contributing to co-morbidity of HIV infection, cytomegalovirus has the propensity to cause multiorgan involvement. We report the case of a 34-year-old seropositive man who presented with bilateral lower limb weakness and symptomatic pallor. He was already on antiretroviral drugs for a month prior to presentation. Detailed clinical examination and laboratory investigations revealed cytomegalovirus polyradiculoneuropathy associated with bone marrow dysplasia. Dysplasia of haematopoeitic cell lines occurs in 30% to 70% of HIV infected patients, and is often indistinguishable from myelodysplastic syndrome. However, in our case, the bone marrow picture reverted back to...

Abstract  Introduction: Human cytomegalovirus is a major cause of morbidity in kidney transplant patients.  Objectives: We aimed to study viral replication and serological response in the first months post kidney transplant in patients undergoing universal prophylaxis or preemptive therapy and correlate the findings with the clinical course of Human cytomegalovirus infection.  Patients and methods: Independent from the clinical strategy adopted for managing Human cytomegalovirus infection, prophylaxis versus preemptive therapy, the pp65 antigenemia assay and serological response were assessed on the day of transplantation, and then weekly during the first three months of post-transplant.  Results: From the 32 transplant recipients, 16 were positive for...

Autores: Zheng,Qi; Xu,Jun; Gao,Huihui; Tao,Ran; Li,Wei; Shang,Shiqiang; Gu,Weizhong.
Human cytomegalovirus is a ubiquitous pathogen that infects the majority of the world's population. After long period of time co-evolving with human being, this pathogen has developed several strategies to evade host immune surveillance. One of the major trick is encoding homologous to those of the host organism or stealing host cellular genes that have signiﬁcant functions in immune system. To date, we have found several viral immune analogous which include G protein coupled receptor, class I major histocompatibility complex and chemokine. Chemokine is a small group of molecules which is deﬁned by the presence of four cysteines in highly conserved region. The four kinds of chemokines (C, CC, CXC, and CX3C) are classiﬁed based on the arrangement of 1 or 2...

Does mycophenolate mofetil increase the risk of cytomegalovirus infection in solid organ transplant recipients?: A mini-review
Provedor de dados: 55
Autores: Song,Alice Tung Wan; Abdala,Edson; Bonazzi,Patrícia Rodrigues; Bacchella,Telésforo; Machado,Marcel Cerqueira César.
Mycophenolate mofetil (MMF) is currently used for prophylaxis of acute rejection in solid organ transplantation. There have been diverging reports regarding an association between MMF and the risk of cytomegalovirus (CMV) infection. We reviewed the main published studies in an attempt to clarify the association between the use of MMF and the risk, frequency and severity of CMV infections. In a search of the Medline database with the terms "mycophenolate" and "cytomegalovir*", 42 articles were found to be relevant; among these, 29 articles were thoroughly analyzed. The first studies on MMF in renal transplantation already showed a tendency towards an association between this drug and the occurrence of CMV disease. Further studies were designed specifically...

Cytomegalovirus (CMV)-related cutaneous necrotizing vasculitis: case report and literature review
Provedor de dados: 55
Autores: Arslan,Ferhat; Batirel,Ayse; Mert,Ali; Ozer,Serdar.
Cytomegalovirus (CMV) infection is usually asymptomatic in immunocompetent patients. A mononucleosis-like syndrome may develop in some patients. Various organ involvements (eg: encephalitis, meningitis, retinitis, myocarditis, pneumonia, hepatitis, enterocolitis, neuritis), which rarely occur in immunocompetent patients, have also been reported. Cutaneous necrotizing vasculitis caused by CMV infection has been reported very rarely in the literature. Here, a case with a very rare clinical form of CMV infection, presenting with persistent fever and livedo reticularis on the extremities and cutaneous necrotizing vasculitis of the toes, is described, and the relevant literature is reviewed. This case report aims to highlight the possibility of CMV infection to...

The best strategy for control of cytomegalovirus (CMV) infection in lung transplant patients is still not determined. The aim of this study was to document the incidence of CMV infection in a cohort of lung transplant recipients under universal prophylaxis with intravenous ganciclovir. All patients received immunosuppressive regimens consisting of cyclosporine, azathioprine, and prednisone. Regardless of CMV serostatus, intravenous ganciclovir was prescribed for every patient in the first 3 months post-transplantation. CMV infection was defined as the detection of CMV pp65 in leukocytes. Eighty-two lung transplant patients were included over a 5-year period. The incidence of CMV infection in the first year post-transplantation was 68.3%, occurring after a...

Autores: Aquino,V.H.; Figueiredo,L.T.M.
A prospective study of cytomegalovirus (CMV) infection was carried out on 34 renal transplant recipients managed at a General Hospital in Ribeirão Preto, SP, Brazil. Serologic tests showed that all patients were infected with CMV before renal transplantation. Two nested-PCR techniques with primers that recognize sequences of the glycoprotein B (gB) and H (gH) genes were used for CMV detection in blood and urine samples during the post-transplantation period. CMV was detected more frequently in blood samples than in urine samples (P&lt;0.001). Thirty-three patients had CMV detected at least once in blood and/or urine samples. Seven of these patients (21.2%) were diagnosed as having symptomatic CMV infection and showed a worse clinical outcome, with a higher...

A prospective analysis of active Human Cytomegalovirus infection (HCMV) was conducted on 33 pediatric renal or hematopoietic stem cell post-transplant patients. The HCMV-DNA positive samples were evaluated for the prevalence of different gB subtypes and their subsequent correlation with clinical signs. The surveillance of HCMV active infection was based on the monitoring of antigenemia (AGM) and on a nested polymerase chain reaction (N-PCR) for the detection of HCMV in the patients studied. Using restriction analysis of the gB gene sequence by PCR-RFLP (Restriction Fragment Length Polymorphism), different HCMV strains could be detected and classified in at least four HCMV genotypes. Thirty-three pediatric recipients of renal or bone marrow transplantation...

Human cytomegalovirus (HCMV) displays genetic variability in several regions, supposed to be related with strain-specific tissue tropism and immunopathogenesis. Based on sequence variation in the UL55 gene that encodes gB glycoprotein, HCMV strains can be assigned to one of four genotypes. Previous studies have addressed gB genotyping mostly by investigating strains derived from immunosuppressed patients, sometimes without previous knowledge about genotype distribution in a geographic area. The present study verified the distribution of HCMV gB genotypes of strains obtained from immunocompetent women at Vitória City, Espírito Santo State, Southeastern, Brazil. The HCMV genome was extracted from their cervical secretion, fetal and maternal placenta tissues...
