Comorbilidades asociadas a la mortalidad por COVID-19 en adultos en Lima, Perú: un estudio de cohorte retrospectiva / Comorbidities associated with COVID-19 mortality in adults in Lima, Peru: a retrospective cohort study

RESUMEN Objetivos. Evaluar las comorbilidades asociadas a la mortalidad en pacientes adultos hospitalizados por COVID-19 de diferentes grupos de edad en hospitales de Lima y Callao. Materiales y métodos. En este estudio de cohorte retrospectiva analizamos datos de pacientes adultos hospitalizados por COVID-19, notificados al Sistema Nacional de Vigilancia Epidemiológica del Ministerio de Salud de Perú de marzo a octubre del 2020. Se estimaron riesgos relativos con intervalos de confianza al 95% mediante modelos de regresión de Poisson con varianza robusta para evaluar las comorbilidades asociadas a la mortalidad por grupos de edad: jóvenes (18-29 años), adultos (30-59 años) y mayores (≥60 años). Resultados. Se incluyeron 2366 jóvenes, 23781 adultos y 25356 adultos mayores en el análisis. Los adultos mayores presentaron la mortalidad más alta (63,7%) en comparación con adultos (27,1%) y jóvenes (8,5%). Independientemente del grupo de edad, la presencia de enfermedad neurológica, enfermedad renal, enfermedad hepática y cáncer se asoció a un mayor riesgo de mortalidad. Adicionalmente, la enfermedad cardiovascular fue también un factor de riesgo en los jóvenes; la obesidad, la diabetes, la enfermedad cardiovascular, la enfermedad pulmonar crónica y la inmunodeficiencia en los adultos; y la obesidad y la enfermedad pulmonar crónica en los mayores. Conclusiones: Independientemente de los grupos de edad, los individuos con enfermedad neurológica crónica, enfermedad renal, enfermedad hepática y cáncer tendrían un alto riesgo de morir por la COVID-19.

ABSTRACT Objectives. To evaluate comorbidities associated with mortality in adult patients hospitalized due to COVID-19 in hospitals in Lima and Callao. Materials and methods. In this retrospective cohort study, we analyzed data from adult patients hospitalized due to COVID-19 reported to the National Epidemiological Surveillance System of the Peruvian Ministry of Health from March to October 2020. We estimated relative risks with 95% confidence intervals using Poisson regression models with robust variance to assess comorbidities associated with mortality by age group: young adults (18-29 years), adults (30-59 years) and older adults (≥60 years). Results. We included 2366 young adults, 23,781 adults and 25,356 older adults. Older adults had the highest mortality (63.7%) compared to adults (27.1%) and young adults (8.5%). Regardless of age group, the presence of neurological disease, renal disease, liver disease, and cancer was associated with an increased risk of mortality. Additionally, cardiovascular disease was also a risk factor in young adults; obesity, diabetes, cardiovascular disease, chronic lung disease, and immunodeficiency in adults; and obesity and chronic lung disease in the elderly. Conclusions. Regardless of age groups, individuals with chronic neurologic disease, renal disease, liver disease, and cancer were at high risk of death from COVID-19.

Clinical features of Guillain-Barré syndrome and factors associated with mortality during the 2019 outbreak in Peru.

INTRODUCTION: Peru has suffered an increase of Guillain Barre Syndrome incidence since 2015, being the biggest outbreak during 2019. We aimed to describe the clinical features, outcomes, and factors associated with mortality among cases reported in the 2019 outbreak. METHODS: Cross-sectional analysis of data from the National Surveillance of Guillain Barre Syndrome of the National Center for Control Disease and Prevention of Peru. We included all cases that met the Brighton criteria, level 1 to level 3. We used multivariable logistic regression to determinate factors associated with mortality. RESULTS: Overall, 772 cases were analyzed (58.7% male; mean age, 41.7 ± 20.3). 86.0% of cases aged over 30 years. 71.4% had a respiratory or gastrointestinal infection in the last 4 weeks. Case fatality rate was 4.3% and 32.2% of survivors reported sequelae. Axonal subtypes were identified in 75.6% of cases with an available nerve conduction study (38.7%). Age and impaired function of cranial nerves were independently associated with mortality. CONCLUSIONS: The 2019 outbreak of Guillain Barre syndrome in Peru was an unprecedented event that affected several regions of the country. Axonal damage was more frequent than demyelinating involvement, which is compatible with findings pointing to Campylobacter jejuni as the triggering agent. The case fatality rate was similar to that reported previously in Peru and other countries, but the high frequency of sequelae is striking.

Comorbidities associated with COVID-19 mortality in adults in Lima, Peru: a retrospective cohort study. / Comorbilidades asociadas a la mortalidad por COVID-19 en adultos en Lima, Perú: un estudio de cohorte retrospectiva.

OBJECTIVES.: Motivation for the study. During the COVID-19 pandemic, the mortality rate from this disease was higher in adults and the elderly. Therefore, it is important to identify the factors that were associated with mortality from COVID-19 in adults, by age group. Main findings. Chronic neurological disease, kidney disease, liver disease, and cancer increased the risk of dying from COVID-19 in the three age groups we analyzed, which were made up of hospitalized patients from Lima and Callao. The risk of mortality associated with comorbidities was higher in patients aged 18 to 29. Implications. This study helps to identify the groups of patients with the highest risk of death from COVID-19, according to age group and type of comorbidity. .

SARS-CoV-2 prevalence associated to low socioeconomic status and overcrowding in an LMIC megacity: A population-based seroepidemiological survey in Lima, Peru.

BACKGROUND: Worldwide, Peru has one of the highest infection fatality rates of COVID-19, and its capital city, Lima, accumulates roughly 50% of diagnosed cases. Despite surveillance efforts to assess the extent of the pandemic, reported cases and deaths only capture a fraction of its impact due to COVID-19's broad clinical spectrum. This study aimed to estimate the seroprevalence of SARS-CoV-2 in Lima, stratified by age, sex, region, socioeconomic status (SES), overcrowding, and symptoms. METHODS: We conducted a multi-stage, population-based serosurvey in Lima, between June 28th and July 9th, 2020, after 115 days of the index case and after the first peak cases. We collected whole blood samples by finger-prick and applied a structured questionnaire. A point-of-care rapid serological test assessed IgM and IgG antibodies against SARS-CoV-2. Seroprevalence estimates were adjusted by sampling weights and test performance. Additionally, we performed RT-PCR molecular assays to seronegatives and estimated the infection prevalence. FINDINGS: We enrolled 3212 participants from 797 households and 241 sample clusters from Lima in the analysis. The SARS-CoV-2 seroprevalence was 20·8% (95%CI 17·2-23·5), and the prevalence was 25·2% (95%CI 22·5-28·2). Seroprevalence was equally distributed by sex (aPR=0·96 [95%CI 0·85-1·09, p = 0·547]) and across all age groups, including ≥60 versus ≤11 years old (aPR=0·96 [95%CI 0·73-1·27, p = 0·783]). A gradual decrease in SES was associated with higher seroprevalence (aPR=3·41 [95%CI 1·90-6·12, p<0·001] in low SES). Also, a gradual increase in the overcrowding index was associated with higher seroprevalence (aPR=1·99 [95%CI 1·41-2·81, p<0·001] in the fourth quartile). Seroprevalence was also associated with contact with a suspected or confirmed COVID-19 case, whether a household member (48·9%, aPR=2·67 [95%CI 2·06-3·47, p<0·001]), other family members (27·3%, aPR=1·66 [95%CI 1·15-2·40, p = 0·008]) or a workmate (34·1%, aPR=2·26 [95%CI 1·53-3·35, p<0·001]). More than half of seropositive participants reported never having had symptoms (56·1%, 95% CI 49·7-62·3). INTERPRETATION: This first estimate of SARS-CoV-2 seroprevalence in Lima shows an intense transmission scenario, despite the government's numerous interventions early established. Susceptibles across age groups show that physical distancing interventions must not be relaxed. SES and overcrowding households are associated with seroprevalence. This study highlights the importance of considering the existing social inequalities for implementing the response to control transmission in low- and middle-income countries.

Barreras identificadas por el personal de salud para el tamizaje del virus de inmunodeficiencia humana en población indígena de la amazonía peruana / Barriers identified by the health staff for the screening of human immunodeficiency virus in indigenous populations of the peruvian amazon

RESUMEN Objetivos. Describir las barreras identificadas por el personal de salud para el tamizaje de virus de inmunodeficiencia humana (VIH) a población indígena en establecimientos de salud de cuatro regiones de la Amazonía peruana. Materiales y métodos. Estudio mixto. La fase cualitativa fue de tipo exploratoria y la fase cuantitativa se basó en un estudio descriptivo transversal de carácter exploratorio. Se seleccionaron 87 establecimientos en los que se aplicó una encuesta, además se realizaron 51 entrevistas a personal de salud de algunos de los establecimientos. Las entrevistas fueron codificadas mediante el software Atlas.ti 7.0. Para las encuestas se realizó un análisis estadístico descriptivo. Resultados. Las barreras identificadas fueron geográficas, socioculturales, y vinculadas al sistema de salud. Fue más frecuente encontrar desabastecimiento de insumos o reactivos en puestos de salud (40,0%) en comparación con los centros de salud (25,0%) y hospitales (11,1%). El principal aspecto que limitó la realización de campañas de tamizaje para el acceso a la población indígena fue la falta de presupuesto (59,3%), la falta de recursos humanos, el que las personas no acepten la toma de muestra de sangre, así como la falta de abastecimiento de insumos o reactivos para las pruebas de diagnóstico. Conclusiones. Las principales barreras identificadas por el personal de salud son en su mayoría las vinculadas al sistema de salud y de índole sociocultural. Se recomienda considerarlas para la mejora de la oferta de los servicios, así como para su adecuación cultural.

ABSTRACT Objective. To describe the barriers identified by the health staff for the screening of human immunodeficiency virus (HIV) in indigenous populations at health centers located in four regions of the Peruvian Amazon. Materials and Methods. Mixed study. The qualitative phase was exploratory and the quantitative phase was based on a cross-sectional descriptive study of exploratory character. Eighty-seven (87) facilities were selected and a survey was applied. Additionally, 51 interviews were conducted to the health staff of some of the establishments. The interviews were codified by means of software Atlas.ti 7.0. For the surveys a descriptive statistical analysis was made. Results. The barriers identified were geographic, sociocultural, and others linked to the health system. It was more frequent to find shortage of inputs or reagents in health centers (40.0%) as compared to clinics and (25.0%) and hospitals (11.1%). The main aspect that limited the screening campaigns for indigenous population was the lack of budget (59.3%), the lack of human resources, people not accepting to have blood samples taken, as well as the lack of supplies or reagents for the diagnostic tests. Conclusions. The main barriers identified by the health staff are mostly those linked to the health system and those of a sociocultural nature. We recommend considering them for the improvement of the supply of the services, as well as for its cultural adjustment.
