    Background and Objectives: Several infections by multidrug-resistant Klebsiella spp. have been report worldwide, because of the capacity of these bacteria in acquire many resistance mechanisms and rapidly spread through clinical units. The aim of this study was evaluate the antimicrobial susceptibility profile of Klebsiella spp. in a hospital of a country town of Rio Grande do Sul, Brazil. Methods: This study investigated the resistance profile of Klebsiella spp. strains isolated between 2014 and 2015, in a regional hospital of a small town. The patient’s charts and microbiological assays were review, including age, sex, date, anatomical site of isolation, origin, and antimicrobial susceptibility test. Results: Forty-two strains were isolated during 2014 and 2015. The positive cultures were from urine (57%), secretions (38%), and blood (5%). Was observed antibiotic resistance in 81% of the strains, and 62% showed multidrugresistance. The resistance profile for ÎČ-lactams, mainly cefalosporin and carbapenem, and for aminoglycosides and tetracycline increased in the study period. Conclusion: In this study we showed an increase in antibiotic resistance in a hospital at a small town, highlighting the emergence of carbapenem resistant Klebsiella spp. during 2015. The spread of multidrug-resistant bacteria in this hospital enhance the importance of epidemiological surveillance and establishment of infection control procedures.JustificaciĂłn y Objetivos: Las infecciones por Klebsiella spp. multirresistentes se han propagado a todas las regiones del mundo debido a su capacidad en adquirir mecanismos de resistencia y la rĂĄpida diseminaciĂłn. El objetivo de essa investigaciĂłn fue determinar el patrĂłn de sensibilidad antimicrobiana de Klebsiella spp. en un hospital del estado de Rio Grande do Sul. MĂ©todos: Se incluyeron todos los casos con cultivos positivos para Klebsiella spp. dentre los años 2014 y 2015. Los datos de los cultivos microbiolĂłgicos y registros mĂ©dicos, edad, sexo, fecha, sitio anatĂłmico del aislamiento, origen y los resultados de las pruebas de sensibilidad a los antimicrobianos fueron obtenidas del pacientes. Resultados: Durante el perĂ­odo se incluyeron 42 casos, 57% de las vĂ­as urinarias, 38% de las secreciones corporales, y 5% del torrente sanguĂ­neo. Se observĂł resistencia en 81% de los casos y resistencia a mĂșltiples fĂĄrmacos en 62%.

    Background:SARS-CoV-2 infected individuals ≄60 years old have the highest hospitalization rates and represent >80% fatalities. Within this population, those in long-term facilities represent >50% of the total COVID-19 related deaths per country. Among those without symptoms, the rate of pre-symptomatic illness is unclear, and potential predictors of progression for symptom development are unknown.Our objective was to delineate the natural evolution of asymptomatic SARS-CoV-2 infection in elders and identify determinants of progression.Methods:We established a medical surveillance team monitoring 63 geriatric institutions. When an index COVID-19 case emerged, we tested all other eligible asymptomatic elders ≄75 or >60 years old with at least 1 comorbidity. SARS-CoV-2 infected elders were followed for 28 days. Disease was diagnosed when any COVID-19 manifestation occurred. SARS-CoV-2 load at enrollment, shedding on day 15, and antibody responses were also studied.Results:After 28 days of follow-up, 74/113(65%) SARS-CoV-2-infected elders remained asymptomatic. 21/39(54%) pre-symptomatic patients developed hypoxemia and ten pre-symptomatic patients died(median day 13.5,IQR 12).Dementia was the only clinical risk factor associated with disease(OR 2.41(95%CI=1.08, 5.39). In a multivariable logistic regression model, dementia remained as a risk factor for COVID-19 severe disease. Furthermore, dementia status showed a statistically significant different trend when assessing the cumulative probability of developing COVID-19 symptoms(log-rank p=0.027).On day 15, SARS-CoV-2 was detectable in 30% of the asymptomatic group while in 61% of the pre-symptomatic(p=0.012).No differences were observed among groups in RT-PCR mean cycle threshold at enrollment(p=0.391) and in the rates of antibody seropositivity(IgM and IgG against SARS-CoV-2 nucleocapsid protein).Conclusions:In summary, 2/3 of our cohort of SARS-CoV-2 infected elders from vulnerable communities in Argentina remained asymptomatic after 28 days of follow-up with high mortality among those developing symptoms. Dementia and persistent SARS-CoV-2 shedding were associated with progression from asymptomatic to symptomatic infection.Fil: Esteban, Ignacio.

    Background: Severity of human metapneumovirus (hMPV) lower respiratory illness (LRTI) is considered similar to that observed for respiratory syncytial virus (RSV). However, differences in severity between these pathogens have been noted, suggesting the degree of illness may vary in different populations. Moreover, a potential association between hMPV and asthma also suggests that hMPV may preferentially affect asthmatic subjects. Methods: In a population-based surveillance study in children aged <2 years admitted for severe LRTI in Argentina, nasopharyngeal aspirates were tested by RT-PCR for hMPV, RSV, influenza A, and human rhinovirus. Results: Of 3947 children, 383 (10%) were infected with hMPV. The hospitalization rate for hMPV LRTI was 2.26 per 1000 children (95% confidence interval [CI], 2.04-2.49). Thirty-nine (10.2%) patients infected with hMPV experienced life-threatening disease (LTD; 0.23 per 1000 children; 95% CI,. 16-.31/1000), and 2 died (mortality rate 0.024 per 1000; 95% CI,. 003-.086). In hMPV-infected children birth to an asthmatic mother was an increased risk for LTD (odds ratio, 4.72; 95% CI, 1.39-16.01). We observed a specific interaction between maternal asthma and hMPV infection affecting risk for LTD. Conclusions: Maternal asthma increases the risk for LTD in children <2 years old hospitalized for severe hMPV LRTI.Fil: Libster, Romina Paula.

    BACKGROUND: Therapies to interrupt the progression of early coronavirus disease 2019 (Covid-19) remain elusive. Among them, convalescent plasma administered to hospitalized patients has been unsuccessful, perhaps because antibodies should be administered earlier in the course of illness. METHODS We conducted a randomized, double-blind, placebo-controlled trial of convalescent plasma with high IgG titers against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in older adult patients within 72 hours after the onset of mild Covid-19 symptoms. The primary end point was severe respiratory disease, defined as a respiratory rate of 30 breaths per minute or more, an oxygen saturation of less than 93% while the patient was breathing ambient air, or both. The trial was stopped early at 76% of its projected sample size because cases of Covid-19 in the trial region decreased considerably and steady enrollment of trial patients became virtually impossible. RESULTS A total of 160 patients underwent randomization. In the intention-to-treat population, severe respiratory disease developed in 13 of 80 patients (16%) who received convalescent plasma and 25 of 80 patients (31%) who received placebo (relative risk, 0.52; 95% confidence interval [CI], 0.29 to 0.94; P = 0.03), with a relative risk reduction of 48%. A modified intention-to-treat analysis that excluded 6 patients who had a primary end-point event before infusion of convalescent plasma or placebo showed a larger effect size (relative risk, 0.40; 95% CI, 0.20 to 0.81). No solicited adverse events were observed. CONCLUSIONS Early administration of high-titer convalescent plasma against SARS-CoV-2 to mildly ill infected older adults reduced the progression of Covid-19.

    Genetics and complement in atypical HUS

    Get PDF
    Central to the pathogenesis of atypical hemolytic uremic syndrome (aHUS) is over-activation of the alternative pathway of complement. Following the initial discovery of mutations in the complement regulatory protein, factor H, mutations have been described in factor I, membrane cofactor protein and thrombomodulin, which also result in decreased complement regulation. Autoantibodies to factor H have also been reported to impair complement regulation in aHUS. More recently, gain of function mutations in the complement components C3 and Factor B have been seen. This review focuses on the genetic causes of aHUS, their functional consequences, and clinical effect
