Human STAT1 gain-of-function iPSC line from a patient suffering from chronic mucocutaneous candidiasis

Publication date: Available online 17 January 2020Source: Stem Cell ResearchAuthor(s): Kathrin Haake, Tim Wüstefeld, Sylvia Merkert, Doreen Lüttge, Gudrun Göhring, Bernd Auber, Ulrich Baumann, Nico LachmannAbstractChronic mucocutaneous candidiasis (CMC) is a disease that is characterized by susceptibility to chronic or recurrent infections with Candida spp. due to mutations affecting mainly the IL17 signaling of T-Cells. The most common etiologies of CMC are gain-of-function (GOF) mutations in the STAT1 gene. In this paper we report the generation of a hiPSC line from a patient suffering from CMC due to a heterozygous GOF STAT1 p.R274Q mutation which can be used for disease modeling purposes.

Publication date: Available online 9 January 2020Source: IDCasesAuthor(s): Abhimanyu Aggarwal,, Karen Hogan,, Armando Paez,AbstractAspergillus endocarditis is a rare cause of culture-negative fungal endocarditis, after Candida endocarditis. Typical risk factors include intravenous drug use, immunosuppression, prior cardiac surgery or presence of prosthetic heart valves, hematopoietic stem cell or solid organ transplantation. Common presentations include signs and symptoms consistent with endocarditis but with negative bacterial blood cultures. Here, we present a case report of a 49-year-old male without known risk factors ...

Conclusions: The PK simulations in this study suggest that transplant recipients on voriconazole prophylaxis against invasive candidiasis or aspergillosis are likely to achieve the target concentrations associated with the desired treatment outcomes if the maintenance dose is 200 mg twice daily. However, Aspergillus spp. with high minimal inhibitory concentrations could require higher maintenance doses.

In this study, a green synthesis approach was used to create a composite hydrogel (CoHy) of RSF stabilized with CarboxymethylCellulose-Na (CMC-Na) and loaded with AgNPs. Their swelling ratios were up to 59 g/g when tested in different physiologically relevant fluids. Material characterizations by Scanning electron microscopy (SEM) with Energy Dispersive X-ray Spectroscopy (EDS), and X-Ray Diffraction (XRD) confirmed the presence of AgNPs on the surface. Antimicrobial properties of the CoHy samples were evaluated using agar diffusion tests. The results showed distinct inhibition zones against major microorganisms found in...

Purpose of review Invasive fungal infections (IFIs) most often occur secondary to acquired immunodeficiency states such as transplantation, AIDS or immune-modulatory treatment for neoplastic and autoimmune disorders. Apart from these acquired conditions, several primary immunodeficiency disorders (PIDs) can present with IFIs in the absence of iatrogenic immunosuppression. This review highlights recent advances in our understanding of PIDs that cause IFIs, which may help clinicians in the diagnosis and management of such infections. Recent findings A growing number of PIDs that cause varying combinations of invasive in...

Conclusions. We discuss the many considerations inherent to planning for HSCT preceded by liver transplant in patients with primary immunodeficiencies, including the role of prolonged immunosuppression and the risk of infection before immune reconstitution. We also discuss the implications of potential recipient sensitization against donor stem cells precipitated by exposure of the recipient to the donor lymphocytes from the transplanted organ.

Authors: Corcione S, Segala FV, Castiglione A, Lupia T, Angilletta R, Cavallo R, Ciccone G, De Rosa FG Abstract Nosocomial infections caused by Clostridium difficile, CP-Kp, ESBL-E or Candida spp. are usually associated with a high mortality rate. In this retrospective study, we evaluated the association between the patient characteristics and the risk of development of nosocomial BSI due to Candida or CP-Kp or ESBL-E. Moreover, we described the cumulative incidence of recurrent infections according to each group of nosocomial BSI. Enteral or parenteral nutrition and indwelling CVC at time of diagnosis were associa...

Invasive fungal infections (IFIs) are an important cause of morbidity and mortality in children with cancer. An overview of studies on the frequency and determinants of IFI in pediatric oncology patients in nonallogeneic stem cell transplantation settings is lacking. We performed a literature review in Pubmed and Embase, and included 13 prospective and 23 retrospective studies. The IFI frequency (proven/probable based on EORTC criteria) in nonallogeneic stem cell transplantation pediatric cancer patients ranged between 1.0% and 38.0%, with the highest frequencies reported in hematologic malignancies. The most common fungal...
