RESUMEN

The COVID-19 pandemic has exacerbated mortality rates among immunocompromised patients, accentuating the need for novel, targeted therapies. Transplant recipients, with their inherent immune vulnerabilities, represent a subgroup at significantly heightened risk. Current conventional therapies often demonstrate limited effectiveness in these patients, calling for innovative treatment approaches. In immunocompromised transplant recipients, several viral infections have been successfully treated by adoptive transfer of virus-specific T-cells (VST). This paper details the successful application of SARS-CoV-2-specific memory T-cell therapy, produced by an interferon-γ cytokine capture system (CliniMACS® Prodigy device), in three stem cell transplant recipients diagnosed with COVID-19 (case 1: alpha variant, cases 2 and 3: delta variants). These patients exhibited persistent SARS-CoV-2 PCR positivity accompanied by bilateral pulmonary infiltrates and demonstrated only partial response to standard treatments. Remarkably, all three patients recovered and achieved viral clearance within 3 to 9 weeks post-VST treatment. Laboratory follow-up investigations identified an increase in SARS-CoV-2-specific T-cells in two of the cases. A robust anti-SARS-CoV-2 S (S1/S2) IgG serological response was also recorded, albeit with varying titers. The induction of memory T-cells within the CD4 + compartment was confirmed, and previously elevated interleukin-6 (IL-6) and IL-8 levels normalized post-VST therapy. The treatment was well tolerated with no observed adverse effects. While the need for specialized equipment and costs associated with VST therapy present potential challenges, the limited treatment options currently available for COVID-19 within the allogeneic stem cell transplant population, combined with the risk posed by emerging SARS-CoV-2 mutations, underscore the potential of VST therapy in future clinical practice. This therapeutic approach may be particularly beneficial for elderly patients with multiple comorbidities and weakened immune systems.

RESUMEN

OBJECTIVES: Our aim was to compare outcomes of hospitalized adults with severe COVID-19 and cytokine storm treated with tocilizumab or baricitinib. METHODS: A prospective, investigational, real-world study was performed from April 2020 to April 2021 at our center. COVID-19 severity was classified by World Health Organization criteria, and cytokine storm was documented along predefined criteria. Eligible patients were enrolled at diagnosis if they fulfilled a priori inclusion criteria and received standard-of-care plus tocilizumab or baricitinib for >48 hours. Patients were followed per protocol for 28 days post-diagnosis. The primary outcome was all-cause mortality; secondary outcomes were invasive mechanical ventilation and major infectious complications. RESULTS: Of 463 patients, 102/463 (22.1%) received tocilizumab, and 361/463 (77.9%) baricitinib. Baseline characteristics were balanced. At 28 days, there was no difference in all-cause mortality (22/102, 21.6% vs 64/361, 17.7%; P-value = 0.38). Requirement for invasive mechanical ventilation was more frequent after tocilizumab (52/102, 50.9% vs 96/361, 26.6%; P <0.01), rate of major infectious complications was similar (32/102, 31.4% vs 96/361, 26.6%; P-value = 0.34). In logistic regression, the immunomodulatory drug was not retained as a predictor of all-cause mortality. Kaplan-Meier analysis revealed statistically similar survival distributions. CONCLUSION: All-cause mortality was similar between adults treated with baricitinib or tocilizumab for severe COVID-19 with cytokine storm.

RESUMEN

In the 3rd year of the program 8 new molecular diagnostic services have been introduced to clinic in the management of breast-, lung-, colorectal cancers as well as in GIST and melanoma. Two patents have been filed for innovative modulation of mito/motogenic signaling pathways in cancer cells. In preclinical models of human cancer a functional imaging technique was developed to detect vascular eff ects of erythropoietin. Using a genomic approach, the sequential changes in human melanoma during systemic dissemination were determined revealing several novel potential prognostic factors and some interesting novel targets for therapy.

RESUMEN

Research on developing molecular diagnostics for hereditary cancers resulted in establishing diagnostic services for familiar polyposis and non-polyposis patients (mutation determination of APC, MYH, STK11, SMAD4, MLH1, MSH2). In familiar testicular cancers the role of gr/gr gene on Y chromosome was identified. Molecular diagnostic tool was established to monitor the progression of follicular lymphoma using Bcl-2/IgH fusion sequences. Molecular diagnostic tools were developed to monitor circulating endothelial precursor cells (CEP) as well and the technique was tested in lung cancer patients. In malignant melanoma we have tested several potential novel markers among which ryanodine receptor seems to be a promising one, while the functional P2X7 receptor may serve as a therapeutic target. We have determined the tyrosine kinase "kinome" profile of HER-2-amplified breast cancers. Furthermore, the "kinome" profile was found to be characteristic for head and neck cancers of various anatomical location. Based on previous studies on the anti-migratory and antimetastatic potential of low-molecular-weight heparins, we have identified short heparin-derived oligosaccharides with maintained antimetastatic- but non-anticoagulant potentials. Pharmacogenomic studies on the role of polymorphism of the serine-hydroxymethyl-transferase (SHMT) gene in the efficacy of 5-FU and FOLFIRI protocols of colorectal cancer patients revealed a significant effect resulting in altered overall survival as well.
