Prevention and control of COVID-19 outbreak in a hemodialysis center.

BACKGROUND: The prevention and control of SARS-CoV-2 infection in hemodialysis (HD) units is challenging. AIM: To describe the clinical characteristics and outcome of patients with chronic kidney disease (CKD) on HD with COVID-19, between March 2020 and January 28, 2021, attending a single HD unit in Bogotá, Colombia. MATERIAL AND METHODS: In this prospective observational study, incidence, prevalence, and case-fatality rate were estimated, including screening results with RT-PCR and anti-SARS-CoV-2 IgG and IgM antibodies in all patients and health personnel in the HD unit. RESULTS: Among patients and health workers, 55 and 9 cases of COVID-19 were identified, respectively. The median age of patients was 63 years (84% males). Fifty five percent of patients were symptomatic, with fever, cough and/or myalgia. The most common comorbidities were hypertension, type 2 diabetes mellitus, and coronary heart disease. The cumulative incidence of infection was 30.2%, population seroprevalence was 24.9%, and fatality was 9.1%. CONCLUSIONS: The incidence of SARS-CoV-2 infection in this HD unit was high. Strict biosafety protocols are required to prevent outbreaks.

Autosomal dominant polycystic kidney disease in Colombia.

BACKGROUND: Autosomal dominant polycystic kidney disease (ADPKD) is the most common genetic cause of chronic kidney disease (CKD) that requires dialysis. Knowing geographical clusters can be critical for early diagnosis, progression control, and genetic counseling. The objective was to establish the prevalence, geographic location, and ethnic groups of patients with ADPKD who underwent dialysis or kidney transplant in Colombia between 2015 and 2019. METHODS: We did a cross-sectional study with data from the National Registry of Chronic Kidney Disease (NRCKD) managed by the High-Cost Diseases Fund (Cuenta de Alto Costo [CAC] in Spanish) between July 1, 2015, and June 30, 2019. We included Colombian population with CKD with or without renal replacement therapy (RRT) due to ADPKD. Crude and adjusted prevalence rates were estimated by state and city. RESULTS: 3,339 patients with ADPKD were included, period prevalence was 9.81 per 100,000 population; there were 4.35 cases of RRT per 100,000 population, mean age of 52.58 years (± 13.21), and 52.78% women. Seventy-six patients were Afro-Colombians, six were indigenous, and one Roma people. A total of 46.07% began scheduled dialysis. The highest adjusted prevalence rate was in Valle del Cauca (6.55 cases per 100,000 population), followed by Risaralda, and La Guajira. Regarding cities, Cali had the highest prevalence rate (9.38 cases per 100,000 population), followed by Pasto, Medellin, and Bucaramanga. CONCLUSIONS: ADPKD prevalence is lower compared to Europe and US; some states with higher prevalence could be objective to genetic prevalence study.

Toxicodermia as an adverse event in a covid-19 patient: case report

ABSTRACT: Introduction: SARS-COV2 infection, which was initially associated with respiratory manifestations only, can also cause gastrointestinal, kidney, neurological and cardiovascular symptoms according to some reports. Case presentation: A 36-year-old female patient attended the emergency department due to dyspnea, asthenia, adynamia, mild odynophagia. and headache. The patient's medical history included obesity, smoking, and working as a health care worker. Considering the symptoms, antimalarial and antiretroviral treatment was indicated to treat COVID-19, a diagnosis that was confirmed three days after admission. However, on the fourth day of treatment, the patient presented with polydipsia and macular, pruritic, and generalized rash. Due to suspicion of toxicoderma, the treatment was suspended, and the skin condition improved. After 8 days of hospitalization, the patient was discharged with biosecurity recommendations and mandatory isolation for 28 days. Conclusion: The described case is a report of toxicoderma in a patient with COVID-19 under treatment with antiretroviral and antimalarial drugs. Based on the findings, a thorough examination of skin and mucosa of patients with suspected or confirmed COVID-19 will undoubtedly contribute to the correct characterization of this new disease.

RESUMEN Introducción. La infección por SARS-COV2, que en principio se pensó solo causaba manifestaciones respiratorias, también puede ocasionar síntomas gastrointestinales, renales, neurológicos, cardiovasculares e incluso cutáneos según algunos reportes. Presentación del caso. Paciente femenina de 36 años quien asistió al servicio de urgencias por cuadró clínico consistente en disnea, astenia, adinamia, odinofagia leve y cefalea. Como antecedentes de relevancia se registró obesidad, tabaquismo y ocupación como trabajadora de la salud. Dados los síntomas, se indicó tratamiento antimalárico y antirretroviral para tratar COVID-19, diagnóstico que fue confirmado a los tres días de ingreso, pero al cuarto día de instaurado este manejo la mujer presentó polidipsia y rash macular, pruriginoso y generalizado. Por sospecha de toxicodermia, el tratamiento fue suspendido y con esto el cuadro cutáneo mejoró. Luego de 8 días de hospitalización, la paciente recibió el alta, junto con recomendaciones de bioseguridad y confinamiento durante 28 días. Conclusiones. El caso descrito corresponde a un evento de toxicodermia en una paciente con COVID-19 en manejo con antirretroviral y antimalárico. A partir de los hallazgos, se establece que la exploración minuciosa de piel y mucosas en los pacientes con sospecha o diagnóstico confirmado de COVID-19 puede ser de gran ayuda para la correcta caracterización de esta nueva enfermedad.

resumen está disponible en el texto completo

Abstract Recent studies have reported the occurrence of thrombotic phenomena or coagulopathy in patients with COVID-19. There are divergent positions regarding the prevention, diagnosis, and treatment of these phenomena, and current clinical practice is based solely on deductions by extension from retrospective studies, case series, observational studies, and international guidelines developed prior to the pandemic. In this context, the aim was to generate a group of recommendations on the prevention, diagnosis and management of thrombotic complications associated with COVID-19. Methods: A rapid guidance was carried out applying the GRADE Evidence to Decision (EtD) frameworks and an iterative participation system, with statistical and qualitative analysis. Results: 31 clinical recommendations were generated focused on: a) Coagulation tests in symptomatic adults with suspected infection or confirmed SARS CoV-2 infection; b) Thromboprophylaxis in adults diagnosed with COVID-19 (Risk scales, thromboprophylaxis for outpatient, in-hospital management, and duration of thromboprophylaxis after discharge from hospitalization), c) Diagnosis and treatment of thrombotic complications, and d) Management of people with previous indication of anticoagulant agents. Conclusions: Recommendations of this consensus guide clinical decision-making regarding the prevention, diagnosis, and treatment of thrombotic phenomena in patients with COVID-19, and represent an agreement that will help decrease the dispersion in clinical practices according to the challenge imposed by the pandemic.

Eficacia y seguridad de la cloroquina, la hidroxicloroquina y la azitromicina en pacientes con COVID-19. Resumen de evidencia / Efficacy and safety of chloroquine, hydroxychloroquine and azithromycin in patients with COVID-19: Summary of evidence

Resumen Introducción: hasta el momento, no se ha demostrado la efectividad de ningún tratamiento para afrontar la emergencia sanitaria por COVID-19. Objetivo: presentar la evidencia disponible respecto a la eficacia y seguridad del uso de cloroquina, hidroxicloroquina y azitromicina en la profilaxis y el manejo de pacientes con COVID-19. Materiales y métodos: se realizó una revisión de la literatura en las bases de datos MEDLINE, Scopus y PubMed sobre publica- ciones que registraran el uso de cloroquina, hidroxicloroquina y azitromicina en pacientes con COVID-19. Resultados: se seleccionaron 12 publicaciones que incluyeron revisiones rápidas de literatura, estudios observacionales y ensayos clínicos. No se encontró información sobre la profilaxis con cloroquina, hidroxicloroquina ni azitromicina para SARS-CoV-2. Los eventos adversos reportados incluyeron emesis, dolor abdominal, náuseas, diarrea, erupción cutánea y picazón. Conclusiones: según la evidencia recopilada el uso de hidroxicloroquina o de cloroquina sola o en combinación con azitromicina en pacientes con COVID-19 no ha mostrado beneficio. Además, cada uno de estos esquemas de tratamiento se asocia con un mayor riesgo de muerte y de episodios de arritmias. En síntesis, la efectividad de estos medicamentos sigue sin estar esclarecida, por lo cual se sugiere evitar su uso en el tratamiento de personas con infección por SARS-CoV-2/COVID-19.

Abstract Introduction: The COVID-19 disease is a health emergency; treatment has not yet been proven.

Resumen Introducción: debido a la emergencia del coronavirus SARS-CoV-2 desde diciembre del 2019, se ha generado un gran volumen de producción científica, en algún caso incierta o controvertida especialmente en el manejo farmacológico de los pacientes con esta infección; por lo tanto, se considera relevante buscar alternativas metodológicas para realizar su síntesis rigurosa, sistemática y de calidad, pero con menor tiempo de ejecución y menor costo. Objetivo: presentar la evidencia disponible respecto al manejo farmacológico de personas con sospecha o diagnóstico de infección respiratoria por SARS-CoV-2 (COVID-19) utilizando el método de revisiones sistemáticas rápidas (RS-R) en medicamentos poten- cialmente eficaces para su manejo. Metodología: se realizó una búsqueda sistemática y estructurada en Medline, Embase, Scopus, Cochrane Library, Clinical trials y Google Scholar en inglés. Los estudios incluidos fueron guías de práctica clínica, consensos, revisiones sistemáticas, metaanálisis, ensayos clínicos y otros estudios primarios. La búsqueda y extracción de datos se realizó por múltiples revisores, pero ninguna fue pareada. Resultados: dieciseis preguntas de interés clínico fueron resueltas, relacionadas con el uso en COVID-19 de lopinavir/ ritonavir, nelfinavir, oseltamivir, remdesivir, ribavirina, teicoplanina, umifenovir, favipiravir, tocilizumab, ivermectina y plasma convaleciente; también se evaluó el uso de medicamentos de soporte e incluidos en el manejo como la dexametasona, así como el uso concomitante de medicamentos que generaron dudas como son los AINES, los IECA y los ARA II. Conclusiones: los resúmenes de evidencia se muestran dentro del escenario de la pandemia como una buena alternativa metodológica para ofrecer información de calidad a corto plazo para los tomadores de decisiones.

Abstract Introduction: Due to the emergence of the SARS-CoV-2 coronavirus since December 2019, a large volume of scientific production has been generated, in some cases uncertain or controversial, especially in the pharmacological management of patients with this infection; therefore, it is considered a relevant search for methodological alternatives to carry out its rigorous, systematic and quality synthesis, but with less execution time and lower cost. Objective: To present the available evidence regarding the pharmacological management of people with suspected or diagnosed respiratory SARS-CoV-2 (COVID-19) using the method of rapid systematic reviews (RS-R) in potentially effective drugs for their management. Methodology: A systematic and structured search was conducted in Medline, Embase, Scopus, Cochrane Library, Clinical trials and Google Scholar in English. Studies included clinical practice guidelines, consensus, systematic reviews, meta-analyses, clinical trials, and other primary studies. Data search and extraction were performed by multiple reviewers, but none were paired. Results: Sixteen questions of clinical interest were resolved, related to the use in COVID-19 of lopinavir/ritonavir, nelfinavir, oseltamivir, remdesivir, ribavirin, teicoplanin, umifenovir, favipiravir, tocilizumab, ivermectin, convalescent plasma; the use of support management drugs such as dexamethasone were also evaluated, as well as the concomitant use of drugs that generated doubts, such as NSAIDs, ACEis, and ARA IIs. Conclusions: Summaries of evidence are within the pandemic scenario as a good methodological alternative to offer quality information in the short term for decision-makers.

Consenso colombiano para la prevención, el diagnóstico y el tratamiento de condiciones trombóticas en adultos con COVID-19: aplicando el Marco de la Evidencia a la Decisión (EtD) GRADE / Colombian consensus for the prevention, diagnosis and treatment of thrombotic conditions in adults with COVID-19: applying GRADE Evidence to Decision (EtD) Frameworks

Introducción estudios recientes han reportado fenómenos trombóticos o coagulopatía en pacientes con COVID-19. Hay posiciones divergentes en cuanto a la prevención, el diagnóstico y el tratamiento de estos fenómenos, y la práctica clínica actual está basada únicamente en deducciones por extensión a partir de estudios retrospectivos, series de casos, estudios observacionales y guías internacionales desarrolladas previas a la pandemia. Objetivo establecer una serie de recomendaciones sobre prevención, diagnóstico y manejo de las complicaciones trombóticas asociadas a COVID-19. Métodos se desarrolló una guía rápida en la que se aplicó el marco de la evidencia a la decisión (EtD) de GRADE y un sistema de participación iterativo, con análisis estadísticos y cualitativos de sus resultados. Resultados se generaron 31 recomendaciones clínicas enfocadas a: a) Pruebas de coagulación en adultos sintomáticos con sospecha de infección o infección confirmada por SARS-CoV-2; b) Tromboprofilaxis en personas adultas con diagnóstico de COVID-19 (escalas de riesgo, tromboprofilaxis de manejo ambulatorio, intrahospitalario y duración de tromboprofilaxis después del egreso de hospitalización), c) Diagnóstico y tratamiento de las complicaciones trombóticas y d) Manejo de personas con indicación previa a usar agentes anticoagulantes. Conclusiones las recomendaciones clínicas de este consenso orientan la toma de decisiones clínicas respecto a prevención, diagnóstico y tratamiento de fenómenos trombóticos en pacientes con COVID-19, y representan un acuerdo que ayudará a disminuir la dispersión en las prácticas clínicas acorde con el desafío que impone la pandemia.

Abstract Introduction: recent studies have reported the occurrence of thrombotic phenomena or coagulopathy in patients with COVID-19. There are divergent positions regarding the prevention, diagnosis, and treatment of these phenomena, and current clinical practice is based solely on deductions by extension from retrospective studies, case series, observational studies, and international guidelines developed prior to the pandemic. Objective: to generate a group of recommendations on the prevention, diagnosis and management of thrombotic complications associated with COVID-19. Methods: a rapid guidance was carried out applying the GRADE Evidence to Decision (EtD) frameworks and an iterative participation system, with statistical and qualitative analysis. Results: 31 clinical recommendations were generated focused on: a) Coagulation tests in symptomatic adults with suspected infection or confirmed SARS CoV-2 infection; b) Thromboprophylaxis in adults diagnosed with COVID-19 (Risk scales, thromboprophylaxis for outpatient, in-hospital management, and duration of thromboprophylaxis after discharge from hospitalization), c) Diagnosis and treatment of thrombotic complications, and d) Management of people with previous indication of anticoagulant agents. Conclusions: recommendations of this consensus guide clinical decision-making regarding the prevention, diagnosis, and treatment of thrombotic phenomena in patients with COVID-19, and represent an agreement that will help decrease the dispersion in clinical practices according to the challenge imposed by the pandemic.

Hallazgos histológicos en biopsia por protocolo asociados con reducción en función renal 12 meses postrasplante, en receptores de trasplante renal con bajo riesgo inmunológico, recibiendo inducción con basiliximab / Histological findings in protocol biopsy associated with reduction in renal function 12 months post transplant in renal transplant recipients with low immunological risk

Resumen Introducción: identificar los factores asociados con pérdida de la función del injerto puede ser un paso importante hacia la prolongación de la sobrevida del injerto renal. Objetivo: determinar la asociación entre los cambios histológicos presentes en las biopsias por protocolo, en el primer año postrasplante en receptores de bajo riesgo inmunológico, recibiendo inducción con basiliximab y pérdida en la función del injerto 12 meses postrasplante. Métodos: se incluyeron pacientes receptores de riñones de donante cadavérico (95 %) o donante vivo (5 %) trasplantados entre agosto de 2007 y julio de 2012. El desenlace primario fue pérdida en la tasa de filtración glomerular calculada (Cockroft & Gault) mayor a 5ml/min 12 meses postrasplante, en comparación con la función renal previa a la biopsia por protocolo. Resultados: la cohorte de estudio estuvo conformada por 114 pacientes, de los cuales 25 presentaron el desenlace principal. Los hallazgos asociados con pérdida de función fueron glomerulitis (p=0,024), inflamación intersticial (p=0,001), tubulitis (p=0,001), capilaritis (p=0,001), glomerulitis + capilaritis (p=0,001), nefropatía por polioma virus (p=0,04) y la presencia de rechazo subclínico (p=0,015). Por análisis de regresión logística la presencia de inflamación intersticial (OR = 2,11; IC 95 %: 1,13-3,95) y capilaritis (0R=7,12; IC 95 %:1,57-32,27) fueron las variables asociadas con pérdida de función del injerto renal 12 meses postrasplante renal. Conclusión: la inflamación intersticial y capilaritis son variables histológicas asociadas con pérdida de función del injerto renal, 12 meses postrasplante, independiente de otras variables.

Abstract Introduction: Identifying factors that are associated of allograft function loss might be an important step toward prolonging kidney allograft survival. Purpose: In this study we found to determine the association between histologic changes on 1-year surveillance biopsies and changes in graft function. Methods: Recipients of kidneys from deceased donors (95%) or living donors (5%) trasplanted between 2007 and 2012. The primary end point was reduction in calculated glomerular filtration rate (Cockroft anf Gault) higher 5ml/min 12 months post transplant vs calculated glomerular filtration rate previous surveillance biopsie. Results: This analysis included 114 adults, recipients of kidneys with low immunological risk receiving basiliximab induction from deceased donors (95%) or living donors (5%), transplanted between august 2007 and july 2012. The primary end point was reduction in calculated glomerular filtration rate (Cockroft & Gault) higher 5ml/min 12 months post trasplant. 25 of 114 patientes showing reduction; The histologic changes associated with renal function reduction were glomerulitis (p=0,024), interstitial inflamation (p=0,001), tubulitis (p=0,001), capilaritis (p=0,001), glomerulitis + capilaritis (p=0,001), polyoma virus nephropathy (p=0,04) and subclinical rejection (p=0,015). By regression analyses, interstitial inflamation (OR = 2,11; IC 95%: 1,13-3,95) and capilaritis (0R=7,12; IC 95%: 1,57-32,27) were associated with renal function reduction 12 month post-transplant. Conclusion: inflammation and capilaritis in protocol biopsies in first year post-transplant predict loss of graft function and independently of other variables.

Early versus delayed erythropoietin for the anaemia of end-stage kidney disease.

BACKGROUND: Anaemia is a common complication in people with chronic kidney disease (CKD) and mainly develops as a consequence of relative erythropoietin (EPO) deficiency. Anaemia develops early in the course of disease and peaks among people with end-stage kidney disease (ESKD). Many types of EPO - also called erythropoiesis-stimulating agents (ESAs) - are used to treat anaemia in people with ESKD.ESAs have changed treatment of severe anaemia among people with CKD by relieving symptoms and avoiding complications associated with blood transfusion. However, no benefits have been found in relation to mortality rates and non-cardiac fatal events, except quality of life. Moreover, a relationship between ESA use and increased cardiovascular morbidity and mortality in patients with CKD has been reported in studies with fully correcting anaemia comparing with partial anaemia correction. Until 2012, guidelines recommended commencing ESA treatment when haemoglobin was less than 11 g/dL; the current recommendation is EPO commencement when haemoglobin is between 9 and 10 g/dL. However, advantages in commencing therapy when haemoglobin levels are greater than 10 g/dL but less than 11 g/dL remain unknown, especially among older people whose life expectancy is limited, but in whom EPO therapy may improve quality of life. OBJECTIVES: To assess the clinical benefits and harms of early versus delayed EPO for anaemia in patients with ESKD undergoing haemodialysis or peritoneal dialysis SEARCH METHODS: We searched the Cochrane Kidney and Transplant Specialised Register to 8 July 2015 through contact with the Trials' Search Co-ordinator using search terms relevant to this review. SELECTION CRITERIA: We planned to include randomised controlled trials (RCTs) and quasi-RCTs evaluating at the clinical benefits and harms of early versus delayed EPO for anaemia in patients with ESKD undergoing haemodialysis or peritoneal dialysis. Studies comparing EPO with another EPO, placebo or no treatment were eligible for inclusion. DATA COLLECTION AND ANALYSIS: It was planned that two authors would independently extract data from included studies and assess risk of bias using the Cochrane risk of bias tool. For dichotomous outcomes (all-cause mortality, cardiovascular mortality, overall myocardial infarction, overall stroke, vascular access thrombosis, adverse effects of treatment, transfusion), we planned to use the risk ratio (RR) with 95% confidence intervals (CI). We planned to calculate the mean difference (MD) and CI 95% for continuous data (haemoglobin level) and the standardised mean difference (SMD) with CI 95% for quality of life if different scales had been used. MAIN RESULTS: Literature searches yielded 1910 records, of these 1534 were screened after duplicates removed, of which 1376 were excluded following title and abstract assessment. We assessed 158 full text records and identified 18 studies (66 records) that were potentially eligible for inclusion. However, none matched our inclusion criteria and were excluded. AUTHORS' CONCLUSIONS: We found no evidence to assess the benefits and harms of early versus delayed EPO for the anaemia of ESKD.
