View Article and Find Full Text PDFLung and colorectal cancers (CRC) have two of the highest mortality rates among all cancer types, and their occurrence and the need for personalized diagnostics and subsequent therapy were not influenced by the COVID-19 pandemics. However, due to the disruption of established delivery chains, standard assays for in vitro diagnostics of those cancers were temporarily not available, forcing us to implement alternative testing methods that enabled at least basic therapy decision making. For this reason, we evaluated rapid testing on the Biocartis Idylla™ platform (Biocartis, Mechelen, Belgium) for four important genes commonly mutated in lung and colorectal cancers, namely EGFR, NRAS, KRAS, and BRAF.

The viral DNA has been identified in colorectal and lung tumors and thus it was postulated that the virus could be associated with tumorigenesis. This assumption was supported by the fact that in HBoV-infected patients and in an in vitro cell culture system, pro-cancerogenic and -fibrotic cytokines were expressed.

Therefore, three formalin fixed paraffin embedded issue sections were screened with the GeneReader Actionable Insights NGS panel (Qiagen, Hilden, Germany) for the occurrence of driver mutations. Several mutations were identified in drug-targetable genes, such as ALK, EGFR, and BRAF.

However, the quantification of this pathogen in the past has revealed discordant results depending on the target gene. As the clinical variety of infections ranges between life-threatening infections and symptom-free colonization, the question arises if qPCRs are reliable tools for quantitative diagnostics of .

Objective: Next Generation Sequencing (NGS) has become a useful tool for gene mutation testing which is required for targeted therapies. The aim of this study was to validate the GeneRead QIAact Actionable Insights Tumor Panel (Qiagen) on the GeneReader System in a diagnostic laboratory setting.
Methods: The GeneRead QIAact Actionable Insights Tumor Panel allows the analysis of 773 variant positions in 12 genes (ALK, BRAF, EGFR, ERBB2, ERBB3, ESR1, KIT, KRAS, NRAS, PDGFRA, PIK3CA and RAF1).
Introduction: The human bocavirus (HBoV) is a parvovirus and is associated with mild to life-threatening acute or persisting respiratory infections, frequently accompanied by further pathogens. So far, there is limited knowledge on the mechanisms of persistence, and no reports on chronic infections or latency have been published so far.
Case Presentation: An immunocompetent male patient suffers from a chronic HBoV1 infection, i.
A clinical case of fatal HBoV infection in an adult cystic-fibrosis patient awaiting lung transplantation is reported. The case is important as the genetic background of the underlying disease is congruent with the background of the sole permissive permanent cell culture CuFi-8 which originates also from a CF patient donor.
View Article and Find Full Text PDFHuman Bocavirus subtype 1 (HBoV1) is associated with respiratory diseases and may contribute to chronic lung diseases by persisting in the infected host. Here the question was addressed if HBoV infections could contribute to fibrogenesis processes as suggested by previously published clinical observations. Cytokine profiles induced by HBoV infection in CuFi-8 air-liquid interphase cell cultures and in bronchoalveolar lavage fluid (BALF) of 20 HBoV-positive and 12 HBoV-negative patients were analysed by semi-quantitative Western spot blot analyses.
