Role of age and comorbidities in mortality of patients with infective endocarditis

[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality. [Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk. [Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality. [Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group

The evolution of the ventilatory ratio is a prognostic factor in mechanically ventilated COVID-19 ARDS patients

Background: Mortality due to COVID-19 is high, especially in patients requiring mechanical ventilation. The purpose of the study is to investigate associations between mortality and variables measured during the first three days of mechanical ventilation in patients with COVID-19 intubated at ICU admission. Methods: Multicenter, observational, cohort study includes consecutive patients with COVID-19 admitted to 44 Spanish ICUs between February 25 and July 31, 2020, who required intubation at ICU admission and mechanical ventilation for more than three days. We collected demographic and clinical data prior to admission; information about clinical evolution at days 1 and 3 of mechanical ventilation; and outcomes. Results: Of the 2,095 patients with COVID-19 admitted to the ICU, 1,118 (53.3%) were intubated at day 1 and remained under mechanical ventilation at day three. From days 1 to 3, PaO2/FiO2 increased from 115.6 [80.0-171.2] to 180.0 [135.4-227.9] mmHg and the ventilatory ratio from 1.73 [1.33-2.25] to 1.96 [1.61-2.40]. In-hospital mortality was 38.7%. A higher increase between ICU admission and day 3 in the ventilatory ratio (OR 1.04 [CI 1.01-1.07], p = 0.030) and creatinine levels (OR 1.05 [CI 1.01-1.09], p = 0.005) and a lower increase in platelet counts (OR 0.96 [CI 0.93-1.00], p = 0.037) were independently associated with a higher risk of death. No association between mortality and the PaO2/FiO2 variation was observed (OR 0.99 [CI 0.95 to 1.02], p = 0.47). Conclusions: Higher ventilatory ratio and its increase at day 3 is associated with mortality in patients with COVID-19 receiving mechanical ventilation at ICU admission. No association was found in the PaO2/FiO2 variation

Treatment with tocilizumab or corticosteroids for COVID-19 patients with hyperinflammatory state: a multicentre cohort study (SAM-COVID-19)

Objectives: The objective of this study was to estimate the association between tocilizumab or corticosteroids and the risk of intubation or death in patients with coronavirus disease 19 (COVID-19) with a hyperinflammatory state according to clinical and laboratory parameters. Methods: A cohort study was performed in 60 Spanish hospitals including 778 patients with COVID-19 and clinical and laboratory data indicative of a hyperinflammatory state. Treatment was mainly with tocilizumab, an intermediate-high dose of corticosteroids (IHDC), a pulse dose of corticosteroids (PDC), combination therapy, or no treatment. Primary outcome was intubation or death; follow-up was 21 days. Propensity score-adjusted estimations using Cox regression (logistic regression if needed) were calculated. Propensity scores were used as confounders, matching variables and for the inverse probability of treatment weights (IPTWs). Results: In all, 88, 117, 78 and 151 patients treated with tocilizumab, IHDC, PDC, and combination therapy, respectively, were compared with 344 untreated patients. The primary endpoint occurred in 10 (11.4%), 27 (23.1%), 12 (15.4%), 40 (25.6%) and 69 (21.1%), respectively. The IPTW-based hazard ratios (odds ratio for combination therapy) for the primary endpoint were 0.32 (95%CI 0.22-0.47; p < 0.001) for tocilizumab, 0.82 (0.71-1.30; p 0.82) for IHDC, 0.61 (0.43-0.86; p 0.006) for PDC, and 1.17 (0.86-1.58; p 0.30) for combination therapy. Other applications of the propensity score provided similar results, but were not significant for PDC. Tocilizumab was also associated with lower hazard of death alone in IPTW analysis (0.07; 0.02-0.17; p < 0.001). Conclusions: Tocilizumab might be useful in COVID-19 patients with a hyperinflammatory state and should be prioritized for randomized trials in this situatio

Spatiotemporal Characteristics of the Largest HIV-1 CRF02_AG Outbreak in Spain: Evidence for Onward Transmissions

Background and Aim: The circulating recombinant form 02_AG (CRF02_AG) is the predominant clade among the human immunodeficiency virus type-1 (HIV-1) non-Bs with a prevalence of 5.97% (95% Confidence Interval-CI: 5.41–6.57%) across Spain. Our aim was to estimate the levels of regional clustering for CRF02_AG and the spatiotemporal characteristics of the largest CRF02_AG subepidemic in Spain.Methods: We studied 396 CRF02_AG sequences obtained from HIV-1 diagnosed patients during 2000–2014 from 10 autonomous communities of Spain. Phylogenetic analysis was performed on the 391 CRF02_AG sequences along with all globally sampled CRF02_AG sequences (N = 3,302) as references. Phylodynamic and phylogeographic analysis was performed to the largest CRF02_AG monophyletic cluster by a Bayesian method in BEAST v1.8.0 and by reconstructing ancestral states using the criterion of parsimony in Mesquite v3.4, respectively.Results: The HIV-1 CRF02_AG prevalence differed across Spanish autonomous communities we sampled from (p &lt; 0.001). Phylogenetic analysis revealed that 52.7% of the CRF02_AG sequences formed 56 monophyletic clusters, with a range of 2–79 sequences. The CRF02_AG regional dispersal differed across Spain (p = 0.003), as suggested by monophyletic clustering. For the largest monophyletic cluster (subepidemic) (N = 79), 49.4% of the clustered sequences originated from Madrid, while most sequences (51.9%) had been obtained from men having sex with men (MSM). Molecular clock analysis suggested that the origin (tMRCA) of the CRF02_AG subepidemic was in 2002 (median estimate; 95% Highest Posterior Density-HPD interval: 1999–2004). Additionally, we found significant clustering within the CRF02_AG subepidemic according to the ethnic origin.Conclusion: CRF02_AG has been introduced as a result of multiple introductions in Spain, following regional dispersal in several cases. We showed that CRF02_AG transmissions were mostly due to regional dispersal in Spain. The hot-spot for the largest CRF02_AG regional subepidemic in Spain was in Madrid associated with MSM transmission risk group. The existence of subepidemics suggest that several spillovers occurred from Madrid to other areas. CRF02_AG sequences from Hispanics were clustered in a separate subclade suggesting no linkage between the local and Hispanic subepidemics

La leishmaniasis visceral en la región de Murcia: estudio multicéntrico 1997-2013

ResumenIntroducciónLa prevalencia de la leishmaniasis visceral (LV), una parasitosis endémica en la cuenca mediterránea, puede verse afectada por movimientos migratorios.ObjetivoEl objetivo de este estudio fue analizar los casos de LV valorados en hospitales de la región de Murcia.Material y métodosSe trata de un estudio retrospectivo multicéntrico de los casos de LV diagnosticados y tratados en los diferentes hospitales de nuestra región, que se agruparon en 2 cohortes: períodoA (pA), el comprendido entre los años 1997 y 2005, y períodoB (pB), el transcurrido entre 2006 y 2013.ResultadosSe analizaron 97 casos de LV (75% fueron hombres y la edad media fue de 35 años), 36 en pA y 61 en pB; el 11% de los pacientes procedían de otros países en pA y el 22% en pB (subsaharianos en 10 casos); el 55% tenían algún tipo de inmunosupresión (80% de ellos estaban diagnosticados de infección por VIH). Las manifestaciones más frecuentes fueron: fiebre (85%) y astenia (66%). La duración media de los síntomas antes de la primera consulta fue de 47días, y el tiempo medio transcurrido entre esta primera consulta y la realización de la prueba diagnóstica, de 13días. El hallazgo más común en la exploración física fue la esplenomegalia (89%), mientras que la trombocitopenia fue el hallazgo de laboratorio más constante (78%). El diagnóstico se confirmó con la detección de amastigotes y/o PCR del aspirado medular en el 61% de los casos; en el 39% restante el aspirado fue negativo y fue necesario el estudio de otras muestras (biopsia de médula ósea, ganglio linfático, laringe, colon, parótida y amígdala, PCR en sangre, serología o inmunocromatografía en orina). El tratamiento más usado fue anfotericinaB liposomal (71%), seguida de glucantime (27%) y anfotericinaB complejo lipídico (1%); en un caso no se pudo averiguar el tratamiento administrado. Se objetivaron 16 recidivas, 11 de ellas en pacientes con sida.ConclusionesAun a riesgo de sesgos propios de estudios retrospectivos y a pesar del mejor control de la infección VIH, observamos en nuestra región un aumento en la frecuencia de casos de LV, probablemente favorecido por el aumento del número de inmigrantes.AbstractIntroductionThe prevalence of visceral leishmaniasis (VL), an endemic parasitic infection in the Mediterranean basin, can be affected by migratory movements.ObjectiveTo analyze VL cases evaluated at several hospitals in the Murcia region.MethodsRetrospective, multicentric study of VL cases; patients were grouped into two time periods: periodA (pA: 1997-2005) and periodB (pB: 2006-2013).ResultsA total of 97 VL cases were analyzed (75% men, mean age 35 years), 36 of them in pA and 61 in pB; 11% and 22% of the patients were foreigners in pA and pB, respectively (10 from sub-Saharan Africa); 55% suffered from some type of immunosuppression (80% HIV). The most common clinical manifestations were fever (85%) and asthenia (66%). The mean duration of symptoms before the first medical contact was 47 days and the average time between the first contact and the microbiological confirmation was 13 days. The most common finding on physical examination was splenomegaly (89%), whereas thrombocytopenia was the most frequent laboratory finding (78%). Diagnoses were confirmed by detection of amastigotes and/or PCR of bone marrow aspiration (BMA) in 61%; in the remaining 39% of cases, BMA was negative and additional samples were necessary (bone marrow, lymph node, larynx, colon, parotid and amygdala biopsy, PCR of blood samples, serology or urine antigen detection). The most commonly used treatment was liposomal amphotericinB (71%), followed by glucantime (27%) and amphotericinB lipid complex (1%). A total of 16 recurrent cases (11 in AIDS patients), were observed.ConclusionsAlthough this is a retrospective study and despite better control of HIV infection, we have observed an increase in the frequency of VL cases in our region, which is probably related to migratory flows
