    Abstract Cytokines are secretion proteins that mediate and regulate immunity and inflammation. They are crucial in the progress of acute inflammatory diseases and autoimmunity. In fact, the inhibition of proinflammatory cytokines has been widely tested in the treatment of rheumatoid arthritis (RA). Some of these inhibitors have been used in the treatment of COVID-19 patients to improve survival rates. However, controlling the extent of inflammation with cytokine inhibitors is still a challenge because these molecules are redundant and pleiotropic. Here we review a novel therapeutic approach based on the use of the HSP60-derived Altered Peptide Ligand (APL) designed for RA and repositioned for the treatment of COVID-19 patients with hyperinflammation. HSP60 is a molecular chaperone found in all cells. It is involved in a wide diversity of cellular events including protein folding and trafficking. HSP60 concentration increases during cellular stress, for example inflammation. This protein has a dual role in immunity. Some HSP60-derived soluble epitopes induce inflammation, while others are immunoregulatory. Our HSP60-derived APL decreases the concentration of cytokines and induces the increase of FOXP3+ regulatory T cells (Treg) in various experimental systems. Furthermore, it decreases several cytokines and soluble mediators that are raised in RA, as well as decreases the excessive inflammatory response induced by SARS-CoV-2. This approach can be extended to other inflammatory diseases.

    Abstract El presente trabajo se realizó en la región litoral del Ecuador, en donde se analizaron los hemogramas de 100 caballos criollos clínicamente sanos, mayores a dos años de edad y criados entre los 0 y 500 metros sobre el nivel del mar, para cumplir con los objetivos de determinar los valores hematológicos de referencia y comparar los resultados obtenidos con los valores de referencia de un estudio previo, realizado a más de 3000 m.s.n.m en la sierra centro norte ecuatoriana. Se obtuvieron las muestras sanguíneas de animales en reposo, se realizaron los análisis de laboratorio con el equipo de auto-hematología Mindray RBC2800Vet y posteriormente se hizo un análisis estadístico utilizando el complemento de Microsoft Excel R“Reference Value Advisor” para determinar los valores de referencia y eliminar los valores anómalos. Se prefirió tomar la muestra de caballos criollos ecuatorianos para tener una muestra con parámetros sanguíneos homogéneos y una referencia de esta variedad antes solamente estudiada sobre los 3000 m.s.n.m. Se encontraron los siguientes valores; eritrocitos: 4,90-9,38x106/mL, hematocrito: 24,83-45,10%, hemoglobina: 8,59-14,87g/L, VCM: 42,35-55,19fL, HCM: 14,25-18,20pg, CHCM: 32,10-36,70g/L, glóbulos blancos: 5,64-12,81x103/mL, linfocitos: 1,04-5,85x103/mL, monocitos: 0,20-0,90x103/mL, granulocitos: 2,90-8,26x103/mL y plaquetas: 78,10-314,90x103/mL. En la comparación con los resultados obtenidos se encontraron diferencias significativas (P<0,05) en el contaje de eritrocitos, concentración de hemoglobina, hematocrito y contaje de plaquetas debido a la influencia de la altura; también se encontraron diferencias significativas (P<0,05) en la serie blanca (leucocitos, linfocitos, monocitos y granulocitos) pero esto debido a influencias fisiológicas o patológicas, mas no al efecto altitudinal.

    Abstract This paper presents the results of an observational and retrospective study on the therapeutic effects of Jusvinza, an immunomodulatory peptide with anti-inflammatory properties for critically ill COVID-19 patients. This peptide induces regulatory mechanisms on the immune response in experimental systems and in patients with Rheumatoid Arthritis. Exploratory research in COVID-19 patients revealed that Jusvinza promotes clinical and radiological improvement. The aim of this study is to describe the clinical outcome and variations of several inflammatory biomarkers in a cohort of critically ill COVID-19 patients, divided into two groups during the observational research: one group received Jusvinza and the other did not. Research physicians extracted the patients´ data from their hospital's clinical records. The study analyzed 345 medical records, and 249 records from critically ill patients were included. The data covered the demographic characteristics, vital signs, ventilatory parameters and inflammatory biomarkers. Survival outcome was significantly higher in the group receiving Jusvinza (90.4%) compared to the group without Jusvinza (39.5%). Furthermore, in patients treated with Jusvinza there was a significant improvement in ventilatory parameters and a reduction in inflammation and coagulation biomarkers. Our findings show that Jusvinza could control the extent of inflammation in COVID-19 patients. This study indicates that Jusvinza is a helpful drug for the treatment of diseases characterized by hyperinflammation.

    Abstract Hyperinflammation distinguishes COVID-19 patients who develop a slight disease or none, from those progressing to severe and critical conditions. CIGB-258 is a therapeutic option for the latter group of patients. This drug is an altered peptide ligand (APL) derived from the cellular stress protein 60 (HSP60). In preclinical models, this peptide developed anti-inflammatory effects and increased regulatory T cell (Treg) activity. Results from a phase I clinical trial with rheumatoid arthritis (RA) patients indicated that CIGB-258 was safe and reduced inflammation. The aim of this study was to examine specific biomarkers associated with hyperinflammation, some cytokines linked to the cytokine storm granzyme B and perforin in a cohort of COVID-19 patients treated with this peptide. All critically ill patients were under invasive mechanical ventilation and received the intravenous administration of 1 or 2 mg of CIGB-258 every 12 h. Seriously ill patients were treated with oxygen therapy receiving 1 mg of CIGB-258 every 12 h and all patients recovered from their severe condition. Biomarker levels associated with hyperinflammation, such as interleukin (IL)-6, IL-10, tumor necrosis factor (TNF-α), granzyme B, and perforin, significantly decreased during treatment. Furthermore, we studied the ability of CIGB-258 to induce Tregs in COVID-19 patients and found that Tregs were induced in all patients studied. Altogether, these results support the therapeutic potential of CIGB-258 for diseases associated with hyperinflammation. Clinical trial registry: RPCEC00000313.

    Abstract The efficacy of protein and carbohydrate antigens as vaccines can be improved via particulate delivery strategies. Here, protein and carbohydrate antigens used in formulations of vaccines against Neisseria menigitidis were displayed on in vivo assembled polyester beads using a combined bioengineering and conjugation approach. An endotoxin-free mutant of Escherichia coli was engineered to produce translational fusions of antigens (Neisseria adhesin A (NadA) and factor H binding protein (fHbp) derived from serogroup B) to the polyhydroxybutyrate synthase (PhaC), in order to intracellularly assemble polyester beads displaying the respective antigens. Purified beads displaying NadA showed enhanced immunogenicity compared to soluble NadA. Both soluble and particulate NadA elicited functional antibodies with bactericidal activity associated with protective immunity. To expand the antigen repertoire and to design a more broadly protective vaccine, NadA-PhaC beads were additionally conjugated to the capsular polysaccharide from serogroup C. Co-delivery of surface displayed NadA and the capsular polysaccharide induced a strong and specific Th1/Th17 mediated immune response associated with functional bactericidal antibodies. Our findings provide the foundation for the design of multivalent antigen-coated polyester beads as suitable carriers for protein and polysaccharide antigens in order to induce protective immunity.

    Abstract The α-l-Lysine (LL) grafting onto the enzymatic poly(gallic acid) (PGAL) produces a helicoidal brush-like antimicrobial polymer containing outer positive-charged moieties. Best results are found with ca. 16 mol% α-LL-grafting for the inhibition of gram-positive Staphylococcus aureus and gram-negative Escherichia coli strains. Membrane permeability, confocal and scanning electron microscopy studies suggest a pore-formation and translocation mechanisms by initial electrostatic interaction of positive charged polymer at the negatively charged bacterial membranes. The attained polymer displays high concentration of hemolysis (Hc) in erythrocytes, and no lymphocyte mitochondrial activity. Interestingly, PGAL-LL is not cytotoxic on human dermal fibroblast. The antioxidant activity after the LL hybridization is also demonstrated by DPPH, ORAC, FRAP and hydroxyl radical scavenging, which enhances the preservation of human cells in addition to antimicrobial for this polymer.

    Abstract Meningococcal disease is caused mainly by serogroups A, B, C, Y, W of N. meningitidis. However, numerous cases of meningitis caused by serogroup X N. meningitidis (MenX) have recently been reported in several African countries. Currently, there are no licensed vaccines against this pathogen and most of the MenX cases have been caused by meningococci from clonal complex (c.c) 181. Detergent extracted meningococcal outer membrane vesicle (dOMV) vaccines have previously shown to be safe and effective against epidemics of serogroup B meningococcal disease in all age groups. The aim of this work is therefore to obtain, characterize and evaluate the vaccine potential of dOMVs derived from a MenX strain (OMVx). Three experimental lots of OMVx were prepared by deoxycholate extraction from the MenX strain BF 2/97. Size and morphology of the vesicles was determined by Dynamic Light Scattering and electron microscopy, whereas the antigenic composition was characterized by gel electrophoresis and immunoblotting. OMVx were thereafter adsorbed to aluminium hydroxide (OMVx/AL) and two doses of OMVx were administered s.c. to groups of Balb/c mice three weeks apart. The immunogenicity and functional antibody activities in sera were evaluated by ELISA (anti-OMVx specific IgG responses) and serum bactericidal activity (SBA) assay. The size range of OMVx was shown to be between 90 and 120nm, whereas some of the antigens detected were the outer membrane proteins PorA, OpcA and RmpM. The OMVx/AL elicited high anti-OMVx antibody responses with bactericidal activity and no bactericidal activity was observed in the control group of no immunised mice. The results demonstrate that OMVx are immunogenic and could form part of a future vaccine to prevent the majority of meningococcal disease in the African meningitis belt.

    Abstract Subtilisin Carlsberg (alkaline protease from Bacillus licheniformis) catalyzes the syntheses of high molecular weights (ca. 20 KDa) cationic α-poly-L-lysine and amphiphilic poly(α-L-lysine-co-L-phenylalanine) in neat organic solvent. The synthesis is conducted in liquid 1,1,1,2-tetrafluoroethane solvent, which is a hydrophobic non-toxic gas that does not deplete the ozone layer and approved for pharmaceutical applications. Solubility of substrates and adequate protease activity in this system with low water environment limits the reaction of hydrolysis of the growing peptide chains. The pressurization of this organic compressed fluid to liquid has low-pressure requirements (25 bar, 40 ºC), and its complete evaporation at atmospheric pressure after completing the reaction ensures solvent-free residues in products. The resulting polypeptides present null cytotoxicity according to MTT and NR analyses, as well as Calcein/EthD-1 assay in human cells.

    Abstract Bloodstream infections due to bacteria are a highly consequential nosocomial occurrences and the organisms responsible for them are usually multidrug-resistant. The aims of this study were to describe the incidence of bacteremia caused by Gram-negative ESKAPE bacilli during the COVID-19 pandemic and characterize the clinical and microbiological findings including antimicrobial resistance. A total of 115 Gram-negative ESKAPE isolates were collected from patients with nosocomial bacteremia (18% of the total bacteremias) in a tertiary care center in Mexico City from February 2020 to January 2021. These isolates were more frequently derived from the Respiratory Diseases Ward (27), followed by the Neurosurgery (12), Intensive Care Unit (11), Internal Medicine (11), and Infectious Diseases Unit (7).
