BACKGROUND CMV intestinal disease (CMV-ID) is a serious complication in immunocompromised patients and mainly diagnosed by clinical, endoscopic and histopathologic findings, whereas qualitative CMV-PCR in tissue samples is not recommended for diagnosis due to its low positive predictive value (PPV). OBJECTIVES To study the interpretation and diagnostic(More)
Increased frequencies of HEV infections have been reported in several industrialized countries. We suggest that this finding might be explained by a better awareness of the disease and not by an increased incidence. Although reported HEV infections increased more than 6-fold in Germany in recent years, the seroprevalence remained unchanged (2 %).
Chronic courses of hepatitis E virus (HEV) infections have been described in immunosuppressed patients. We aimed to study the role of HEV infections in heart transplant recipients (HTR). 274 HTR were prospectively screened for HEV infection using an anti-HEV-IgG ELISA and HEV-PCR. In addition, 137 patients undergoing cardiac surgery (non-HTR) and 537(More)
Although infections with the novel pandemic 2009 influenza A (H1N1) virus (A/H1N1/2009) appeared to be relatively mild during the first summer of circulation ('off season'), there has been significant morbidity and hospitalization and several fatal cases. Thus, rapid detection of A/H1N1/2009 is crucial for efficient treatment and infection control measures.(More)
Human adenovirus (HAdV) infection after hematopoietic stem cell transplantation (HSCT) is associated with significant morbidity and mortality in children. The optimal surveillance and treatment strategies are under discussion. Here, we present data from 238 consecutive pediatric allogeneic HSCT recipients who underwent transplantation in a single center who(More)
BACKGROUND Human adenoviruses (HAdV) can cause disseminated disease as a severe complication after haematopoietic stem cell transplantation (SCT) and may originate from the reactivation of latent infections. However, data about the clinical relevance of HAdV DNAaemia and disease in adults are scarce. OBJECTIVES To retrospectively analyse the outcome of(More)
Patients treated with BRAF inhibitors (e.g. vemurafenib), a novel targeted therapy for advanced melanoma harbouring certain BRAF mutations, develop numerous adverse cutaneous side effects, including skin tumors such as squamous cell carcinoma or non-malignant verruciform keratinocyte proliferations, termed 'BRAF-inhibitor-associated verrucous keratosis(More)
According to the Banff guidelines for renal transplants, pure endothelialitis without any tubulointerstitial infiltrates (with the Banff components v ≥ 1, i0, t0) has to be called acute cellular rejection (ACR). The pathophysiology of this rare lesion abbreviated as v_only is currently unclear, as well as its clinical, serological, and prognostic(More)
INTRODUCTION Virus-associated hemophagocytic syndrome (VAHS) is a severe complication of various viral infections often resulting in multiorgan failure and death. The purpose of this study was to describe baseline characteristics, development of VAHS, related treatments and associated mortality rate of consecutive critically ill patients with confirmed 2009(More)
Nonmelanoma skin cancer (NMSC) shows a strongly increased incidence in solid organ transplant recipients (OTRs) and AIDS patients, suggesting an infectious etiology. The role of certain viruses, i.e., cutaneous human papillomaviruses (HPVs), in NMSC in immunosuppressed patients remains controversial. Merkel cell polyomavirus (MCPyV), which was recently(More)
