    This study describes the diversity of parasites in ophidian species from four ecoregions of Valle del Cauca and Gorgona Island (Colombian Pacific). For this, samples from necropsies, blood and feces were collected from 37 snakes belonging to the species Bothrops asper (terrestrial), Leptodeira annulata (semiarboreal), Imantodes cenchoa (arboreal), Sibon nebulatus (arboreal), Boa constrictor (semiarboreal), Clelia clelia (terrestrial), Mastigodryas boddaerti (terrestrial) and Micrurus mipartitus (terrestrial). Parasite detection was performed using stereoscopic and optical microscopy, and/or concentration and staining methods depending on the sample type; parasites were identified by morphological keys. Eleven snakes (29.7%) belonging to four species were infected with at least one of seven parasite taxa identified (six nematodes and one hemoparasite). Among nematodes, the families Rhabditidae and Oxyuridae, and the genus Kalicephalus were found for the first time in L. annulata. Worms of the order Strongylida, and the genera Kalicephalus and Ophidascaris were identified in B. asper. Hepatozoon spp. (hemoparasite) presented the highest prevalence of infection, which was only infecting arboreal and semi-arboreal snakes (L. annulata, I. cenchoa and B. constrictor), showing in addition morphological variability of the gametocytes. Our findings suggest that transmission of this parasite may be associated with snake habits and lifestyle.El presente estudio describe la diversidad de endoparásitos en ocho especies de ofidios de las cuatro ecorregiones del Valle del Cauca e Isla Gorgona en Colombia. Para la detección e identificación de parásitos, se obtuvieron muestras de sangre, materia fecal, órganos y tejidos de 37 serpientes pertenecientes a las especies Bothrops asper (terrestre), Leptodeira annulata (semi-arborícola), Imantodes cenchoa (arborícola), Sibon nebulatus (arborícola), Boa constrictor (semi-arborícola), Clelia clelia (terrestre), Mastigodryas boddaerti (terrestre) y Micrurus mipartitus (terrestre). La búsqueda e identificación de parásitos se realizó mediante el uso de microscopia óptica y esteroscópica, y/o métodos de concentración y coloración dependiendo del tipo de muestra; los parásitos fueron identificados mediante claves morfológicas. Once serpientes (29,7%) pertenecientes a cuatro especies estuvieron infectadas con al menos uno de siete taxones parásitos identificados (seis nematodes y un hemoparásito). Entre los nematodes se reportan por primera vez las familias Rhabditidae y Oxyuridae y el género Kalicephalus en L. annulata; en B. asper se identificaron parásitos del orden Strongylida y de los géneros Kalicephalus y Ophidascaris. Hepatozoon spp. (hemoparásito) presentó la prevalencia de infección más elevada, y sólo se halló en I. cenchoa, L. annulata y B. constrictor, de hábitos arbóreo y semiarbóreo, evidenciándose además variabilidad morfológica de los gametocitos. Los hallazgos indican que la transmisión de esta parasitosis puede estar relacionada con el hábito y modo de vida de estas serpientes.Asociación Parasitológica Argentin

    (1) Aims: To assess the incidence of inflammatory bowel disease (IBD) in Spain, to describe the main epidemiological and clinical characteristics at diagnosis and the evolution of the disease, and to explore the use of drug treatments. (2) Methods: Prospective, population-based nationwide registry. Adult patients diagnosed with IBD-Crohn's disease (CD), ulcerative colitis (UC) or IBD unclassified (IBD-U)-during 2017 in Spain were included and were followed-up for 1 year. (3) Results: We identified 3611 incident cases of IBD diagnosed during 2017 in 108 hospitals covering over 22 million inhabitants. The overall incidence (cases/100,000 person-years) was 16 for IBD, 7.5 for CD, 8 for UC, and 0.5 for IBD-U; 53% of patients were male and median age was 43 years (interquartile range = 31-56 years). During a median 12-month follow-up, 34% of patients were treated with systemic steroids, 25% with immunomodulators, 15% with biologics and 5.6% underwent surgery. The percentage of patients under these treatments was significantly higher in CD than UC and IBD-U. Use of systemic steroids and biologics was significantly higher in hospitals with high resources. In total, 28% of patients were hospitalized (35% CD and 22% UC patients, p < 0.01). (4) Conclusion: The incidence of IBD in Spain is rather high and similar to that reported in Northern Europe. IBD patients require substantial therapeutic resources, which are greater in CD and in hospitals with high resources, and much higher than previously reported. One third of patients are hospitalized in the first year after diagnosis and a relevant proportion undergo surgery

    [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

    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

    Importancia clínica del Streptococcus agalactiae como causante de infección

    No full text
    El Streptococcus agalactiae o estreptococo ß-hemolítico del grupo b (S. b) es causa importante de sepsis neonatal y de infecciones en gestantes y adultos inmunocomprometidos. Se trata de una bacteria encapsulada cuya virulencia se atribuye a una toxina polisacárida y se caracteriza por presentar una alta concentración inhibitoria mínima (CIM) a la penicilina. Su papel como patógeno potencial se ha reconocido ampliamente en países industrializados donde en la actualidad se desarrollan estrategias de diagnóstico y prevención dada su alta morbimortalidad; sin embargo, en países en desarrollo no se informa con frecuencia la infección por este germen, básicamente debido a la circulación de serotipos menos virulentos y la falta de una búsqueda y diagnóstico adecuados. La experiencia de la Fundación Valle del Lili, Cali, Colombia, revela en poco tiempo la presencia frecuente de esta bacteria como colonizante y como origen de infecciones severas en neonatos y adultos, con una resistencia moderada a la penicilina y alta a la gentamicina y tetraciclina. Por las implicaciones de esta infección y por lo imperativo de conocer más acerca de ella, se revisan las características de la infección y de los casos, con lo que se pretende alertar sobre la presencia de este germen en Cali a fin de orientar hacia estrategias adecuadas para mejorar su descubrimiento en el laboratorio y hacer un buen diagnóstico y un manejo terapéutico eficaz. Streptococcus agalactiae (Lancefield group B Streptococcus) (GBS) has been recognized over the last few years as the main etiological agent of serious neonatal disease and maternal peripartum infections in the developed world. Group B streptococcal disease may also be an emerging public health problem among non-pregnant adults, particularly those with serious underlying disease. The potential virulence of this bacterium is attributable to its capsulate and a high inhibitory concentration to penicillin. In industrialized countries the report of invasive disease is more frequent than in developing countries. A possible explanation for this, could be other prevalent serotypes, inappropriate diagnosis and inadequate screening techniques to detect GBS. In our hospital we found frequently GBS vaginal colonization in mothers and nonpregnant women, and also we have seen GBS infection in adults and invasive infection in neonates. Those isolates were highly resistant to gentamicin and tetracycline and moderate to penicillin. In order to know the impact of GBS infection in Colombia we need more studies. In this review it is proposed, that is imperative to guide efforts to promote the use of strategies to prevent it, particularly in neonates. Besides this, in order to decrease the morbility and mortality for GBS infection, it is very important to have a good detection and identification of GBS in the microbiology laboratory, a better clinical diagnosis, and opportune and effective treatment

    Por la ubicuidad de las micobacterias no tuberculosas (MNTBs) en el ambiente y la alta prevalencia observada en VIH positivos cuya interpretación era confusa, se realizó un estudio para determinar la prevalencia de MNTBs en la población general y saber cuál era la naturaleza del hallazgo de MNTBs en VIH positivos. Se comparó un grupo de 101 individuos VIH positivos del Servicio Integrado de Enfermedades Infecciosas del Instituto de Seguro Social y 100 individuos controles sin riesgo para infección por VIH. En ambos grupos se tomaron muestras de jugo gástrico para tinción y cultivo. La prevalencia de micobacterias en los VIH positivos fue 7% así: TBC, 2%; y MNTBs, 5%. Las MNTBs aisladas fueron: M. gordonae, 2; M. szulgai, 1; M. fortuitum, 1; y M. avium, 1, todas tan sólo en el cultivo y en pacientes de estadío IV; sin embargo, apenas un caso se asoció con enfermedad. En los controles la prevalencia fue 6%: 1 micobacteria se encontró en el Ziehl Neelsen pero no se aisló en cultivo y las 5 restantes que se aislaron en cultivo, eran M. szulgai; ninguna se asoció con enfermedad. No se encontró asociación entre pH, mucosidad, celularidad, leucocitos y otras características del jugo gástrico en las muestras de pacientes con y sin MNTBs. Por consiguiente, se pudo concluir que la prevalencia de MNTBs fue igual tanto en VIH positivos como en el grupo de las personas con factores de riesgo a la infección, población general y bastante menor que la encontrada en un estudio previo. En los VIH positivos la presencia de MNTBs se asoció con estadíos avanzados de la infección y con el consumo de antibióticos orales. El hallazgo de MNTBs obedece a una exposición al ambiente contaminado; por lo general se trata de colonizaciones y su significado clínico en individuos con infección por el VIH está supeditado a las condiciones inmunológicas del enfermo. La presencia de MNTBs se considera dentro del contexto clínico del paciente y amerita una evaluación detallada con estudios repetidos
