Detection of cytomegalovirus (CMV) antigenemia was compared with shell vial centrifugation cultures for rapid detection of CMV infection. In a prospective study, 59 CMV seropositive patients were monitored weekly during the first 100 days after allogeneic marrow transplantation for virus excretion from urine, throat, and blood and for antigenemia by direct staining of peripheral leukocytes usin...

In a prospective study, the cytomegalovirus (CMV) pp65 antigenemia assay was compared with detection of CMV by blood culture in 67 consecutive CMV-seropositive patients undergoing autologous marrow or peripheral blood stem cell transplantation. Antigenemia occurred in 26 patients (38.8%) a median of 33 days (range, 12-74) after transplant. Viremia was detected in 5 patients (7.5%) a median of 3...

A nested PCR was used for the detection of human cytomegalovirus (HCMV) DNA in plasma. The presence of HCMV DNA and its correlation to pp65 leukocytic antigenemia were investigated with 299 blood samples from 45 organ transplant recipients and 63 AIDS patients. Of the 53 samples positive by nested PCR, 52 (98%) were also positive for leukocytic antigenemia and 23 had high levels of antigenemia ...

BACKGROUND/AIMS Patients with ulcerative colitis (UC) are at high risk for cytomegalovirus (CMV) reactivation. The usefulness of the CMV antigenemia assay in active UC patients has rarely been studied. We assessed whether the assay detects CMV colitis and predicts clinical outcomes in patients with UC. METHODS We retrospectively reviewed the medical records of patients hospitalized for modera...

OBJECTIVES To evaluate the contribution of breastfeeding to Rotavirus (RV)-induced antigenemia and/or RNAemia and disease severity in Indian children (<2 yrs age). METHODS Paired stool and serum samples were collected from (a) hospitalized infants with diarrhea (n = 145) and (b) healthy control infants without diarrhea (n = 28). Stool RV-antigen was screened in both groups by commercial rapid...

BACKGROUND Preemptive therapy with ganciclovir (GCV) based on the results of a cytomegalovirus (CMV) antigenemia assay is a standard strategy for preventing CMV disease after allogeneic hematopoietic cell transplantation (HCT). However, the appropriate threshold of antigenemia-positive cells for deciding when to start GCV remains unclear. PATIENTS This retrospective study included 80 recipien...

A cohort study of 214 human immunodeficiency virus (HIV)-infected patients was performed to assess the usefulness of the cytomegalovirus (CMV) antigenemia assay for predicting the occurrence of CMV disease and death. Multivariate analysis revealed that only positive baseline CMV antigenemia assays (relative risk [RR], 7.2; 95% confidence interval [CI], 3.7-14.2; P = .0001) and CD4 cell counts (...

BACKGROUND AND OBJECTIVES Hematopoietic stem cell transplant (HSCT) recipients after show rising levels of antigenemia during pre-emptive ganciclovir treatment of human cytomegalovirus (HCMV) infection. This raises some doubts about the therapeutic decisions to be taken. DESIGN AND METHODS Three groups of HSCT recipients with HCMV infection undergoing anti-viral treatment were identified: gro...

OBJECTIVE This study was conducted to examine the association between rotavirus antigenemia and clinical features, particularly extraintestinal manifestations, and the association between serum cytokine levels and rotavirus antigen quantity. METHODS Sixty hospitalized children who received a diagnosis of acute rotavirus gastroenteritis were enrolled in this study. Paired serum samples were co...

American Samoa began a territory-wide mass drug administration (MDA) program with diethylcarbamazine and albendazole in 2000 after baseline surveys indicated that 16.5% of 2,989 residents were infected with Wuchereria bancrofti based on tests for circulating filarial antigen. Follow-up surveys were conducted in 2001, 2003, and 2006, using convenience samples of residents of sentinel villages. A...
