Aspergillus and cytomegalovirus are major causes of morbidity/mortality after haploidentical hematopoietic transplantation. The high degree of mismatching makes cell immunotherapy impossible as it would result in lethal graft-versus-host disease (GvHD). We generated large numbers of donor T-cell clones specific for Aspergillus or cytomegalovirus antigens. We identified clones potentially respon...

Lung function of patients with heart failure is characterized by a variety of changes proposed as being due to passive congestion, secondary pulmonary fibrosis, and/or recurrent pulmonary emboli. A diffusion impairment thought to be due to cyclosporine has also been noted in patients following heart transplantation. Similar changes of unclear origin have been observed in renal transplant recipi...

Background Accurate diagnosis of Pneumocystis jirovecii pneumonia (PJP) is challenging, and the delayed PJP associated with high mortality in patients connective tissue disease (CTD). Metagenomic next-generation sequencing (mNGS) technology facilitates etiological various infectious diseases, promising application diagnosing PJP. This study aimed to investigate value mNGS using bronchoalveolar ...

A spectrum of blood-borne infectious agents is transmitted through transfusion of infected blood donated by apparently healthy and asymptomatic blood donors. The diversity of infectious agents includes hepatitis B virus (HBV), hepatitis C virus (HCV), human immunodeficiency viruses (HIV-1/2), human T-cell lymphotropic viruses (HTLV-I/II), Cytomegalovirus (CMV), Parvovirus B19, West Nile Virus (...

The appearance of primary HIV infection ranges from an asymptomatic presentation to a symptomatic illness resembling infectious mononucleosis. Severe unusual presentations include acute myopericarditis, renal failure, and opportunistic infections such as esophageal candidiasis, cytomegalovirus infection, and Pneumocystis jirovecii pneumonia. We report a case of multiple organ failure during pri...

Pulmonary complications are frequent in patients treated with high-dose chemotherapy and autologous bone marrow transplantation for breast cancer or other solid tumours. This study analyses the development of lung toxicity, changes in respiratory function and occurrence of clinical symptoms in a group of 24 patients (mean age 46+/-7 yrs) who underwent high-dose sequential chemotherapy (HDS) wit...

HIV-infected individuals with severe immunodeficiency are at risk of opportunistic infection (OI). Tuberculosis (TB) may occur without substantial immune suppression suggesting an early and sustained adverse impact of HIV on Mycobacterium tuberculosis (MTB)-specific cell mediated immunity (CMI). This prospective observational cohort study aimed to observe differences in OI-specific and MTB-spec...

The highly regulated secretion of effector cytokines by CD4+ T cells plays a critical role in immune protection against pathogens such as cytomegalovirus. Here, we directly compare the frequency and functional characteristics of cytomegalovirus-specific CD4+ memory/effector T cells in normal and HIV+ subjects using a novel, highly efficient multiparameter flow cytometric assay that detects the ...

OBJECTIVE To determine the seroprevalence of anti-Toxoplasma, anti-Rubella, and anti-Cytomegalovirus (CMV) antibodies among pregnant women receiving prenatal care at Van Training and Research Hospital. MATERIALS AND METHODS In developing countries, various infectious agents encountered in the gestational period are important because they influence both maternal and fetal health. Among these, ...

Cytomegalovirus infection is one of most frequent infectious complications after renal transplantation, and can be classified as primo-infection, when the transmission occurs through the graft, or reactivation, when the recipient is cytomegalovirus seropositive. After transplantation, cytomegalovirus can appear as an infection, when the patient presents with evidence of viral replication withou...
