BACKGROUND Breast cancer is a leading cause of death among women worldwide. Increasing evidence implies that human cytomegalovirus (HCMV) infection is associated with several malignancies. We aimed to examine whether HCMV is present in breast cancer and sentinel lymph node (SLN) metastases. MATERIALS AND METHODS Formalin-fixed paraffin-embedded tissue specimens from breast cancer and paired s...

BACKGROUND Multiple strains infection of human cytomegalovirus (HCMV) was found to be correlated with increased viral load in immunodeficient patients. However, the pathogenic mechanism underlying this correlation remains unclear. To evaluate genetic polymorphisms of HCMV glycoprotein and their potential role in its viral load, HCMV glycoprotein B, N, and O (gB, gN and gO) genotypes was studied...

BACKGROUND The aim of this study was to investigate the involvement of CMV infection in wheezing infants and the association between CMV-DNA and immunoglobulins (Igs). MATERIAL AND METHODS A total of 243 wheezing infants and 3,000 parturients were enrolled in this study. The infants were randomly grouped to receive blood HCMV-DNA tests (n=46) or urine HCMV-DNA tests (n=197). Furthermore, all pa...

Gliomas are the most common primary central nervous system (CNS) neoplasms in humans. Human cytomegalovirus (HCMV) has been described to be associated with gliomas, though the exact mechanisms of HCMV in oncogenesis are unclear. In this study, the investigation of detecting HCMV in the tumor tissues and peripheral blood of patients with newly diagnosed gliomas were performed to enrich medical k...

BACKGROUND Human cytomegalovirus (HCMV) is an important pathogen of viral pneumonia in children. The diagnosis of acute HCMV infection is complicated and difficult. METHODS Clinical and laboratory data of 6063 hospitalized children with respiratory infection and 509 with respiratory virus infection alone were retrospectively analyzed. Urine and respiratory specimens of 186 hospitalized childr...

BACKGROUND Biliary atresia (BA) is the most severe hepatic disorder in newborns and its etiopathogenesis remains unknown. Viral involvement has been proposed, including the human cytomegalovirus (HCMV). The aims of the study were to use the polymerase chain reaction (PCR) to screen the liver tissue of infants with extrahepatic cholestasis for HCMV and to correlate the results with serological a...

In allogeneic hematopoietic stem-cell transplantation (HSCT) recipients, outcome of human cytomegalovirus (HCMV) infection results from balance between viral load/replication and pathogen-specific T-cell response. Using a cut-off of 30,000 HCMV DNA copies/ml blood for pre-emptive therapy and cut-offs of 1 and 3 virus-specific CD4(+) and CD8(+) T cells/µl blood for T-cell protection, we conducte...

INTRODUCTION This study aimed to determine the prevalence of congenital and perinatal human cytomegalovirus (HCMV) infections among newborns in two major neonatal intensive care units (NICU) in Bahrain. METHODOLOGY One hundred newborns comprised of 84 preterm and 16 term babies admitted to the NICUs were enrolled in the study. During the first six weeks of life, urine and saliva was obtained ...

In order to assess the value of human cytomegalovirus (HCMV) DNA amplification of gastrointestinal biopsies, we studied 57 human immunodeficiency virus-infected patients with and without gastrointestinal HCMV diseases. After DNA extraction, a 406-bp fragment from the unique short region of the HCMV genome was amplified by 35 cycles of polymerase chain reaction (PCR) and semiquantified from 80 t...

The synthesis of human cytomegalovirus (HCMV) envelope glycoproteins and the production of infectious HCMV in human astrocytoma and skin fibroblast (SF) cells were analysed. HCMV envelope glycoproteins synthesized in astrocytoma cells had lower Mrs than the same glycoproteins synthesized in SF cells regardless of the strain of HCMV used, showing that the differences observed were due to differe...
