VG161 activates systemic anti‐tumor immunity in pancreatic cancer models as a novel oncolytic herpesvirus expressing multiple immunomodulatory transgenes

alexandrossfakianakis shared this article with you from Inoreader VG161 activates systemic anti‐tumor immunity in pancreatic cancer models as a novel oncolytic herpesvirus expressing multiple immunomodulatory transgenes via Journal of Medical Virology Abstract The VG161 represents the first recombinant oncolytic herpes simplex virus type 1 carrying multiple synergistic anti-tumor immuno-modulating factors. Here, we report its anti-tumor mechanisms and thus provide firm theoretical foundation for the upcoming clinical application in pancreatic cancer. Generally, the VG161-mediated anti-tumor outcomes were analyzed by a collaboration of techniques, namely the single cell sequencing, airflow-assisted desorption electrospray ionization-mass spectrometry imaging (AFADSI-MSI) and Nanostring techniques. In vitro, the efficacy of VG161 together with immune checkpoint inhibitors (ICIs) has been successfully shown to grant a long-term anti-tumor effect by altering tumor immunity and remodeling tumor microenvironment (TME) metabolisms. Cellular functional pathways and cell subtypes detected from patient samples before and after the treatment had undergone distinctive changes including upregulated CD8+ T and NK cells. More importantly, significant antitumor signals have emerged since the administration of VG161 injection. In conclusion, VG161 can systematically activate acquired and innate immunity in pancreatic models, as well as improve the tumor immune microenvironment, indicative of strong anti-tumor potential. The more robusting anti-tumor outcome for VG161 monotherapy or in combination with other therapies on pancreatic cancer is worth of being explored in further clinical trials.

Virome analysis provides new insights into the association between viruses and Parkinson's disease

alexandrossfakianakis shared this article with you from Inoreader Virome analysis provides new insights into the association between viruses and Parkinson's disease via Journal of Medical Virology Abstract Parkinson's disease (PD) is a kind of neurodegenerative disease that causes a huge burden to society. Previous studies have suggested the association between PD and multiple viruses. However, there is still a lack of a virome study about PD. This study systematically identified viruses from the public RNA-Seq data of more than 700 samples from both PD patients and the control group (most were healthy people). Only nine viruses such as Human betaherpesvirus 5 and Merkel cell polyomavirus have been detected in several human brain tissues of the central nervous system, the appendix, and blood of PD patients, and all of these viruses were also detected in the control group. Most viruses were observed to have low abundance in no more than three tissues. No statistically significant differences were observed between the virus abundance in the PD patients and the control group for all viruses. The positive rates of most viruses in PD patients were higher or similar to that in the control group, although those were less than 5% for most viruses. Overall, this is the first study to systematically investigate the virome in PD patients, and provides new insights into the association between viruses and PD.

Non‐neutropenic fever in children with cancer: Management, outcomes and clinical decision rule validation

alexandrossfakianakis shared this article with you from Inoreader Non‐neutropenic fever in children with cancer: Management, outcomes and clinical decision rule validation via Pediatric Blood & Cancer Abstract Introduction Fever and infection are an important complication of childhood cancer therapy. Most research and guideline development has focussed on febrile neutropenia, with a paucity directed at non-neutropenic fever (NNF). We describe the clinical presentation, management and outcomes of NNF in children with cancer, and externally validate the Esbenshade Vanderbilt (EsVan) clinical decision rules (CDR) to predict bacteraemia. Method Using a prospective database, retrospective data were collected on consecutive NNF episodes (fever ≥38.0°C and absolute neutrophil count >1.0 cells/mm3). Sensitivity, specificity and area under the receiver operator characteristic curve (AUC-ROC) of the CDR were compared to derivation study. Results There were 203 NNF episodes occurring in 125 patients. Severe sepsis was uncommon (n = 2, 1%) and bacteraemia occurred in 10 (4.9%, 95% confidence interval [CI]: 2.7%–8.8%) episodes. A confirmed or presumed bacterial infection requiring antibiotics occurred in 31 (15%) patients. Total 202 (99%) episodes received at least one dose of intravenous broad-spectrum antibiotic and 141 (70%) episodes were admitted to hospital. Six (3%) episodes required intensive care unit (ICU)-level care and there were no infection-related deaths. The EsVan 1 rule had an AUC-ROC of 0.67, 80% were identified as low risk, and sensitivity and specificity were 50% and 81.5%, respectively, for a risk threshold of 10%. Conclusions Serious infection and adverse outcome are uncommon in children with NNF. Many children did not have a bacterial cause of infection identified, but were still treated with broad-spectrum antibiotics and admitted to hospital. National clinical practice guidelines should be developed for this important cohort to enable risk stratification and optimise antibiotic management. Further research is required to determine appropriateness of EsVan CDR in our cohort. View on Web

Mini‐hyper CVD + CRIB (condensed rituximab, inotuzumab ozogamicin, and blinatumomab) for refractory pediatric B‐acute lymphoblastic leukemia

alexandrossfakianakis shared this article with you from Inoreader Mini‐hyper CVD + CRIB (condensed rituximab, inotuzumab ozogamicin, and blinatumomab) for refractory pediatric B‐acute lymphoblastic leukemia via Pediatric Blood & Cancer Abstract Relapsed or refractory pediatric patients with B-acute lymphoblastic leukemia (B-ALL) have high rates of toxicities and relapse, and novel therapy is needed. We present a case of a 5-year-old male child with high-risk B-ALL that was refractory to several re-induction regimens. He was put into minimal residual disease-negative remission after re-induction with chemotherapy plus overlapping rituximab, inotuzumab ozogamicin, and blinatumomab, termed mini-hyper-CVD (cyclophosphamide, vincristine, and dexamethasone) plus CRIB (condensed rituximab, inotuzumab ozogamicin, and blinatumomab). This regimen was well tolerated, and he received his transplant and engrafted with no significant infections, toxicities, or sinusoidal obstruction syndrome. This is the first reported use of a condensed sequential immunotherapy/chemotherapy regimen in a pediatric leukemia patient. View on Web

Analysis of oral microbiota alterations induced by Helicobacter pylori infection and vonoprazan‐amoxicillin dual therapy for Helicobacter pylori eradication

alexandrossfakianakis shared this article with you from Inoreader Analysis of oral microbiota alterations induced by Helicobacter pylori infection and vonoprazan‐amoxicillin dual therapy for Helicobacter pylori eradication via Helicobacter Abstract Background The oral cavity is considered a potential reservoir of Helicobacter pylori (H. pylori), and the imbalance of oral microbiota directly reflects the health of the host. We aimed to explore the relationship among oral microbiota, H. pylori infection, and vonoprazan-amoxicillin (VA) dual therapy for H. pylori eradication. Methods Helicobacter pylori-positive patients were randomized into low- or high-dose VA dual therapy (i.e., amoxicillin 1 g b.i.d. or t.i.d. and vonoprazan 20 mg b.i.d) for 7 or 10 days. H. pylori-negative patients served as normal controls. Saliva samples were collected from 41 H. pylori-positive patients and 13 H. pylori-negative patients. The oral microbiota was analyzed by 16S rRNA gene sequencing, followed by bioinformatics analysis. Results Helicobacter pylori-positive patients had higher richness and diversity and better evenness of oral microbiota than normal controls. Beta diversity analysis estimated by Bray–Curtis or weighted UniFrac showed distinct clustering between H. pylori-positive patients and normal controls. The number of bacterial interactions was reduced in H. pylori-positive patients compared with that in negative patients. Forty-one patients evaluated before and after successful H. pylori eradication were divided into low (L-VA) and high dose (H-VA) amoxicillin dose groups. The alpha and beta diversity of the oral microbiota between L-VA and H-VA patients exhibited no differences at the three time points (before eradication, after eradication, and at confirmation of H. pylori infection cure). Conclusion Helicobacter pylori infection could alter the diversity, composition, and bacterial interactions of the oral microbiota. Both L-VA and H-VA dual therapy showed minimal influence on the oral microbiota. View on Web

Association of viral load with TRAIL, IP‐10, CRP biomarker signature and disease severity in children with respiratory tract infection or fever without source: a prospective, multicentre cohort study

alexandrossfakianakis shared this article with you from Inoreader Association of viral load with TRAIL, IP‐10, CRP biomarker signature and disease severity in children with respiratory tract infection or fever without source: a prospective, multicentre cohort study via Journal of Medical Virology Abstract Background To investigate the association of viral load (VL) with (i) tumor necrosis factor-related apoptosis inducing ligand (TRAIL), interferon-gamma induced protein-10, C-reactive protein and a combinatorial score (BV score); and (ii) clinical severity. Study Design In this prospective, multicentre cohort sub-study, children with respiratory tract infection or fever without source were enrolled. VL for influenza virus, rhinovirus, respiratory syncytial virus, and adenovirus were measured from nasopharyngeal swabs. The reference standard diagnosis was established based on expert panel adjudication. Results Of 1140 recruited patients, 333 had a virus mono-detection. VL for the aggregated dataset correlated with TRAIL and IP-10 levels, with length of oxygen therapy, and inversely with the BV score. On single viral level, only influenza virus yielded a correlation with TRAIL, IP-10 levels, and the BV score. Children with a viral reference standar d diagnosis had significantly higher VL than those with bacterial infection (p = 0.0005). Low TRAIL (incidence rate ratio, IRR 0.6, 95% confidence interval, CI 0.39-0.91) and young age (IRR 0.62, 95%CI 0.49-0.79) were associated with longer hospital stay, while young age (IRR 0.33, 95%CI 0.18-0.61), low TRAIL (IRR 0.25, 95%CI 0.08-0.76), and high VL (IRR 1.16, 95%CI 1.00-1.33) were predictive of longer oxygen therapy. Conclusion These findings indicate that VL correlates with biomarkers and may serve as a complementary tool pertaining to disease severity. This article is protected by copyright.

Survival Outcomes of Patients with Mycosis Fungoides Involving the External Ear and Ear Canal

alexandrossfakianakis shared this article with you from Inoreader Survival Outcomes of Patients with Mycosis Fungoides Involving the External Ear and Ear Canal via The Laryngoscope This manuscript reports our retrospective review of 40 patients with mycosis fungoides, and it demonstrates a comparison in outcomes of patients with ear involvement with those without ear involvement. Overall survival was shorter when the ear canals were involved. Objectives/Hypothesis Mycosis Fungoides (MF) is the most common subtype of cutaneous T-cell lymphoma. Disease involvement of specific locations may be more significant than simply the symptoms associated with that site; it is possible that involvement of certain sites could be associated with poor prognosis. We aimed to evaluate the outcomes of patients with MF with documented involvement of the EAC and external ear. Study Design Retrospective analysis. Methods We retrospectively reviewed 40 patients with MF that were treated by otologists between 2012 and 2021. Results We report the largest series of patients with MF involving the external ear and EAC. Of the 40 patients included in this study, 17 presented with Mycosis Fungoides in the otologic region (MFO). Of these 17 MFO patients, 2/17 had involvement of the external ear only, 3/17 of the EAC only, 11/17 of both the external ear and EAC, and 1/17 of the periauricular skin. Of note, 11/14 (79%) patients presenting with EAC disease died compared to11/26 (42%) of patients without involvement. In addition, eight of the 13 (62%) patients with external ear involvement died compared to 14/27 (52%) of patients without involvement. Ear canal involvement was associated with a statistically significant shorter overall survival duration in patients with MF (p = 0.03). Furthermore, disease in the EAC was found to have a hazard ratio value of 2.565 (CI 1.102–5.970). Conclusions Involvement of the EAC by MF portends a poor prognosis. This finding highlights the need for a more in-depth otologic evaluation of patients with MF. Level of Evidence Level 4 Laryngoscope, 2022 View on Web
