Exploring the chemical and pharmacological variability of Lepidium meyenii: a comprehensive review of the effects of maca.

Maca (Lepidium meyenii), a biennial herbaceous plant indigenous to the Andes Mountains, has a rich history of traditional use for its purported health benefits. Maca's chemical composition varies due to ecotypes, growth conditions, and post-harvest processing, contributing to its intricate phytochemical profile, including, macamides, macaenes, and glucosinolates, among other components. This review provides an in-depth revision and analysis of Maca's diverse bioactive metabolites, focusing on the pharmacological properties registered in pre-clinical and clinical studies. Maca is generally safe, with rare adverse effects, supported by preclinical studies revealing low toxicity and good human tolerance. Preclinical investigations highlight the benefits attributed to Maca compounds, including neuroprotection, anti-inflammatory properties, immunoregulation, and antioxidant effects. Maca has also shown potential for enhancing fertility, combating fatigue, and exhibiting potential antitumor properties. Maca's versatility extends to metabolic regulation, gastrointestinal health, cardio protection, antihypertensive activity, photoprotection, muscle growth, hepatoprotection, proangiogenic effects, antithrombotic properties, and antiallergic activity. Clinical studies, primarily focused on sexual health, indicate improved sexual desire, erectile function, and subjective wellbeing in men. Maca also shows promise in alleviating menopausal symptoms in women and enhancing physical performance. Further research is essential to uncover the mechanisms and clinical applications of Maca's unique bioactive metabolites, solidifying its place as a subject of growing scientific interest.

Comparison of different definitions of metabolic syndrome and their relationship with cardiovascular risk estimation / Comparación de diferentes definiciones de síndrome metabólico y su relación con la estimación del riesgo cardiovascular

Abstract Introduction: Multiple definitions of metabolic syndrome (MS) are used in Peru, and there is currently no consensus on which definition should be used in clinical practice. Objectives: To compare cardiovascular disease (CVD) risk estimators, obtained using the ACC/AHA ASCVD Risk Calculator, and to assess their level of agreement with different definitions of MS in patients treated in Lima, Peru. Materials and methods: Analytical cross-sectional study. Medical records, collected through consecutive sampling, of 233 patients treated between October and December 2019 at the Hospital Nacional Hipólito Unanue, Lima, Peru, were reviewed. CVR risk was calculated using the online ACC/AHA ASCVD Risk Calculator, and the MS definitions of the WHO, NCEP-ATP III, IDF, AHA/NHLBI, JIS and ALAD were considered to compare CVD risk according to each definition. Agreement between the different MS definitions was calculated using the kappa coefficient based on the six levels of strength of agreement described by Landis and Koch. Results: The median CVD risk in patients with MS according to the definitions of the WHO, NCEP-ATP III, IDF, AHA/NHLBI, ALAD and JIS was 9.6 (3.9-20.35), 7.9 (3.1-18.6), 7.3 (3- 16.5), 7.8 (3-17.6), 7.1 (2.9-16.5), and 7.1 (3.1-16.5), respectively. The prevalence of MS according to JIS, IDF, ALAD, AHA/NHLBI, NCEP-ATP III and WHO definitions was 81.97%, 80.26%, 74.68%, 67.81%, 65.67%, and 51.14%, respectively. Agreement between the JIS criteria and the IDF, ALAD, NCEP-ATP III, and AHA/NHLBI criteria was 0.944, 0.787, 0.592, and 0.567, respectively, but it was 0.286 between the JIS criteria and the WHO criteria. Conclusions: In Peru, there are differences between CVD risk estimates depending on the MS definition used and considered in the present study, which may have an impact on the intensity of the therapeutic and preventive interventions performed in these patients.

Correlation between stress and lifestyle in teachers at some schools in Lima, Peru, during telework in 2020.

BACKGROUND: Stress and unhealthy lifestyle are serious problems in public health and education, particularly due to their significant relevance in the context of the COVID-19 pandemic. OBJECTIVES: To determine the correlation between stress and lifestyle in teachers at some schools in Lima, Peru, during telework in 2020. METHODS: This observational, quantitative, analytical, cross-sectional study was conducted in 217 school teachers from Lima. Lifestyle was measured using the FANTASTIC questionnaire; stress was measured using the Teaching Stress Scale (ED-6), comprised of the anxiety, depression, maladaptive beliefs, work pressure and poor coping dimensions. The Spearman correlation between numerical variables, and the difference of the FANTASTIC score according to the categorical variables, were analyzed with the Mann-Whitney U test or Kruskal-Wallis test, as necessary. Multivariable analysis was done with a multiple linear regression model to find raw and adjusted ß (ßa). RESULTS: The median of the ED-6 scale was 81 (RI: 64-105). Sixty-four percent of the teachers had a good-excellent lifestyle; 27.2%, regular; and 8.49%, bad-dangerous. The FANTASTIC score had an inverse correlation with ED-6 (ßa: -0.16, 95%; CI: -0.20 to -0.12) adjusted for age and cohabitation with children. Likewise, teachers between 40 and 49 years old (ßa: 2.89, 95%; CI: 0.17 to 5.62) had a better lifestyle; and teachers who lived with children (ßa: -5.48, 95%; CI: -7.89 to -3.06), a worse lifestyle. CONCLUSIONS: As stress increased, the lifestyle quality worsened in teachers at some schools in Lima, Peru, during telework in 2020.

Perception of risk to COVID-19 and mental health indicators in workers of a Peruvian hospital: An analytical cross-sectional study. / Percepción de riesgo a COVID-19 e indicadores de salud mental en trabajadores de un hospital peruano: estudio transversal analítico.

Introduction: COVID-19 has caused great fear on health professionals and could affect their mental health, therefore it is important to determine the association between the perception of risk to COVID-19 and mental health in workers of a Peruvian hospital. Methods: Analytical cross-sectional study, through virtual survey. The dependent variables were: depression, anxiety and stress; The independent variable was perception of risk to COVID-19 and the covariates: sociodemographic, family, work and clinical data. Crude and adjusted prevalence ratios were found with a 95% confidence interval and a significance level of 5%. Results: There was no association between risk perception and depression (adjusted prevalence ratio: 0.98 95% confidence interval: 0.89 to 1.08), anxiety (adjusted prevalence ratio: 0.94 95% confidence interval: 0.89 to 1.00), stress (adjusted prevalence ratio: 0.89 95% confidence interval 0.76 to 1.04). In the multivariate analysis, an association was found between depression with direct contact with the COVID-19 patient (adjusted prevalence ratio: 2.06, 95% confidence interval: 1.14 to 3.70) and with having a comorbidity (adjusted prevalence ratio: 2.56 95% confidence interval: 1.52 to 4.30); likewise, between anxiety with number of children (adjusted prevalence ratio: 1.09 95% confidence interval: 1.00 to 1.18), with direct contact with COVID-19 patient (adjusted prevalence ratio: 2.67 95% confidence interval 1.46 to 4.85) and having comorbidity (adjusted prevalence ratio: 2.00 95% confidence interval: 1.40 to 2.86); finally, between stress with direct contact with the COVID-19 patient (adjusted prevalence ratio: 2.86, 95% confidence interval: 1.20 to 6.83). Conclusions: No statistically significant association was found between risk perception and depression, anxiety, or stress. However, there was an association between depression, anxiety, and stress, each with direct contact with COVID-19 patients; between anxiety and depression, each with having comorbidities and, finally, anxiety with the number of children.

Mortality and associated risk factors in patients hospitalized due to COVID-19 in a Peruvian reference hospital.

OBJECTIVES: To determine the risk factors for in-hospital mortality in patients with COVID-19 from a Peruvian national hospital. METHODS: Retrospective cohort study of medical records of patients with COVID-19 hospitalized at Hospital Nacional Hipólito Unanue (HNHU) during the months of April to August 2020. The dependent variable was in-hospital mortality. Independent variables included sociodemographic and clinical characteristics, physical examination findings, oxygen saturation (SaO2) at admission, treatment received during hospitalization and laboratory results at admission. A Cox regression model was used to evaluate the crude and adjusted hazard ratios for associated factors. RESULTS: We included 1418 patients. Median age was 58 years (IQR 47-68 years) and 944 (66.6%) were male. The median length of hospitalization was 7 (4-13) days, and the mortality rate was 46%. The most frequent comorbidities were type 2 diabetes mellitus, hypertension, and obesity. In the adjusted analysis, mortality was associated with age (HR 1.02; 95%CI 1.02-1.03), history of surgery (HR 1.89; 95%CI 1.31-2.74), lower oxygen saturation at admission (HR 4.08; CI95% 2.72-8.05 for SaO2<70% compared to SaO2>94%), the presence of poor general condition (HR 1.81; 95% CI 1.29-2.53), altered state of consciousness (HR 1.58; 95%CI 1.18-2.11) and leukocyte levels (HR 1.01; 95%CI 1.00-1. 02). Treatment with ivermectin (HR 1.44; 95%CI 1.18-1.76) and azithromycin (HR 1.25; 95%CI 1.03-1.52) were associated with higher mortality. Treatment with corticosteroids at low to moderate doses was associated with lower mortality (HR 0.56 95%CI 0. 37-0. 86) in comparison to no steroid use. CONCLUSION: A high mortality was found in our cohort. Low oxygen saturation at admission, age, and the presence of hematological and biochemical alterations were associated with higher mortality. The use of hydroxychloroquine, ivermectin or azithromycin was not useful and was probably associated with unfavorable outcomes. The use of corticosteroids at moderate doses was associated with lower mortality.

Asociación entre enfermedades cardiometabólicas y depresión en un hospital de referencia peruano / Association between cardiometabolic diseases and depression in a Peruvian reference hospital

INTRODUCCIÓN: Se ha postulado la relación entre la presencia de enfermedades cardiometabólicas con problemas de salud mental, en particular la depresión. OBJETIVOS: Determinar la asociación entre la presencia de enfermedades cardiometabólicas y la presencia de sintomatología depresiva evaluada mediante el cuestionario PHQ-9 en pacientes atendidos en consultorios externos de medicina interna del Hospital Nacional Hipólito Unanue. METODOLOGÍA: Estudio observacional, analítico, transversal. Se definió enfermedad cardiometabólica como la presencia de diabetes mellitus, hipertensión arterial, dislipidemia, y/u obesidad. Se utilizó el cuestionario PHQ-9 para evaluar la presencia de síntomas sugerentes de depresión. Se evaluó la asociación cruda y ajustada a posibles confusores. Para el análisis multivariado se utilizó un modelo de regresión de Poisson para hallar razones de prevalencia con sus respectivos intervalos de confianza al 95%. Se consideró un p<0,05 como estadísticamente significativo. Resultados: Se incluyeron 252 pacientes, de los que 205 (81,4%) presentaron enfermedades cardiometabólicas y 181 (71,9%) presentaron síntomas consistentes con algún grado de depresión. La presencia de enfermedades cardiometabólicas se asoció a síntomas depresivos tanto en el análisis crudo (RPc 1,43; IC 95% 1,08-1,89; p=0,012) como en el ajustado (RPa 1,31; IC 95% 1,00-1,71; p=0,048). Adicionalmente se encontró asociación entre el sexo femenino y sintomatología depresiva (RPa 1,35; IC 95% 1,11-1,63; p=0,002). CONCLUSIONES: La presencia de enfermedades cardiometabólicas se asoció con la presencia de síntomas depresivos en pacientes atendidos en la consulta externa de medicina interna. El abordaje de la salud mental debe ser parte integral del manejo multidisciplinario del paciente con enfermedad cardiometabólica.

INTRODUCTION: It has been postulated the relationship between presence of cardiometabolic diseases with mental health problems, particularly depression. Objectives: To determine the association between cardiometabolic diseases and presence of depressive symptoms, evaluated by PHQ-9 questionnaire, in patients attended at the outpatient clinic of internal medicine service at Hospital Nacional Hipolito Unanue. METHODS: Observational analytical cross-sectional study. Cardiometabolic disease was defined as the presence of diabetes mellitus, high blood pressure, dyslipidemia, and/or obesity. The PHQ-9 questionnaire was used to evaluate the presence of symptoms suggestive of depression. The association was evaluated crude and adjusted for possible confounders. For the multivariate analysis, a Poisson regression model was used to find prevalence ratios with their respective 95% confidence intervals. A p<0.05 was considered statistically significant. RESULTS: 252 patients were included, of which 205 (81,4%) presented cardiometabolic diseases and 181 (71,9%) presented symptoms consistent with some grade of depression. The presence of cardiometabolic diseases was associated with depressive symptoms both in the crude analysis (PRc 1.43; CI 95% 1.08-1.89; p=0.012) and in the adjusted one (PRa 1.31; CI 95% 1.00-1.71; p=0.048). Additionally, an association was found between female sex and depressive symptoms (PRa 1,35; CI 95% 1,11-1,63; p=0,002). CONCLUSIONS: The presence of cardiometabolic diseases was associated with the presence of depressive symptoms in patients seen at the outpatient clinic of internal medicine. The mental health approach should be an integral part of the multidisciplinary management for the patient with cardiometabolic disease.

[Enteroparasitosis in Peru and its relation to the Human Development Index]. / Enteroparasitosis en Perú y su relación con el Índice de desarrollo humano.

BACKGROUND: Diseases related to enteroparasites are a serious public health problem. OBJECTIVE: To assess the prevalence of enteroparasites in Peru and its relationship with the Human Development Index (HDI). MATERIAL AND METHODS: A coproparasitological study using the direct method from children and adults from the communities of Pamplona Alta in Lima, the province of San Sebastián de Quera, Castillo Grande, Pillco Marca and Puelles in Huánuco, Llupa-Huaraz in Ancash, and Machaguay in Arequipa, Peru, was carried out from 2012 to 2016. RESULTS: 864 samples were analyzed, and a total prevalence of 23.03% (199 cases) was found. The non-pathogenic protozoan Entamoeba coli, with 10.42% (90 cases), and the nematode Ascaris lumbricoides, with 6.37% (55 cases), were the most prevalent. PERMANOVA analysis based on the prevalences of enteroparasites in urban and rural areas of Peru showed differences among communities. The overall prevalence of urban communities was similar to that of the rural ones. CONCLUSIONS: Enteroparasitosis in Peru are not related to HDI. However, the levels of infestation by enteroparasites varied between the different communities, and they were related to the bioecological characteristics of parasites.

INTRODUCCIÓN: las enfermedades relacionadas con enteroparásitos son un grave problema de salud pública. OBJETIVO: evaluar la prevalencia de enteroparásitos en el Perú y su relación con el Índice de desarrollo humano (IDH). MATERIAL Y MÉTODOS: se realizó un estudio coproparasitológico por el método directo en niños y adultos de las comunidades de Pamplona Alta en Lima, de la provincia de San Sebastián de Quera, Castillo Grande, Pillco Marca y Puelles en Huánuco, Llupa-Huaraz en Ancash y Machaguay en Arequipa, Perú, de 2012 a 2016. RESULTADOS: se analizaron 864 muestras y se encontró una prevalencia total del 23.03% (199 casos). El protozoario no patógeno Entamoeba coli con 10.42% (90 casos) y el nematodo Ascaris lumbricoides con 6.37% (55 casos) fueron los más prevalentes. La prevalencia de protozoos fue mayor que la de los helmintos. No se observó asociación entre el IDH frente a la prevalencia total ni frente a las cuatro especies de enteroparásitos más frecuentes. El análisis PERMANOVA a partir de las prevalencias de enteroparásitos en áreas urbanas y rurales de Perú mostró diferencias entre las comunidades. La prevalencia total de las comunidades urbanas fue similar a la de las rurales. CONCLUSIONES: la enteroparasitosis en el Perú no se relaciona con el IDH. Sin embargo, los niveles de infestación por enteroparásitos variaron entre las diferentes comunidades y se relacionaron con las características bioecológicas de los parásitos.

Resultados: se analizaron 864 muestras y se encontró una prevalencia total del 23.03% (199 casos). El protozoario no patógeno Entamoeba coli con 10.42% (90 casos) y el nematodo Ascaris lumbricoides con 6.37% (55 casos) fueron los más prevalentes. La prevalencia de protozoos fue mayor que la de los helmintos. No se observó asociación entre el IDH frente a la prevalencia total ni frente a las cuatro especies de enteroparásitos más frecuentes. El análisis PERMANOVA a partir de las prevalencias de enteroparásitos en áreas urbanas y rurales de Perú mostró diferencias entre las comunidades. La prevalencia total de las comunidades urbanas fue similar que la de las rurales. Conclusiones: la enteroparasitosis en el Perú no se relaciona con el IDH. Sin embargo, los niveles de infestación por enteroparásitos variaron entre las diferentes comunidades y se relacionaron con las características bioecológicas de los parásitos.

Background: Diseases related to enteroparasites are a serious public health problem. Objective: To assess the prevalence of enteroparasites in Peru and its relationship with the Human Development Index (HDI). Material and methods: A coproparasitological study using the direct method from children and adults from the communities of Pamplona Alta in Lima, the province of San Sebastián de Quera, Castillo Grande, Pillco Marca and Puelles in Huánuco, Llupa-Huaraz in Ancash, and Machaguay in Arequipa, Peru was carried out from 2012 to 2016. Results: 864 samples were analyzed, and a total prevalence of 23.03% (199 cases) was found. The non-pathogenic protozoan Entamoeba coli, with 10.42% (90 cases), and the nematode Ascaris lumbricoides, with 6.37% (55 cases), were the most prevalent. PERMANOVA analysis based on the prevalences of enteroparasites in urban and rural areas of Peru showed differences among communities. The overall prevalence of urban communities was similar to that of rural ones. Conclusions: Enteroparasitosis in Peru are not related to HDI. However, the levels of infestation by enteroparasites varied between the different communities, and they were related to the bioecological characteristics of parasites.

Factors associated with the non-use of health services in LGBTI people from Peru. / Factores asociados a la no utilización de servicios de salud en personas LGBTI de Perú.

OBJECTIVE: To determine the factors associated with the non-use of health services in a sample of the lesbian, gay, bisexual, transgender, and intersex population of Peru. MATERIALS AND METHODS: Analytical cross-sectional study, analysis of secondary data from the First LGBTI Survey of Peru. Those who suffered from a medical condition during the last twelve months and had to receive medical attention were considered a variable of interest. Crude prevalence ratios (PRc) and adjusted (PRa), with 95% confidence intervals (95% CI) were calculated using Poisson regressions with robust variance. Three models were developed, adjusted to variables grouped according to sexual orientation, gender identity, and intersexuality. RESULTS: 55.4% were male at birth, the median age was 25 years (IR: 21-30). 16% stated that they had not sought medical attention. The three models presented a negative association in having suffered a chronic disease, infectious, contagious diseases, and mental illness and those who expressed their orientation openly. Not being respected for the gender they identified with was related to not using the services in model 3. Models 1 and 3 included a positive association with not being respected with the gender identified. CONCLUSION: Suffering from a mental illness, an infectious contagious disease, a chronic disease, and not being treated with respect according to their gender identity are factors associated with the non-use of health services.

OBJETIVO: Determinar los factores asociados a la no utilización de servicios de salud en una muestra de la población de lesbianas, gais, bisexuales, transgénero e intersexuales (LGBTI) de Perú. MATERIALES Y MÉTODOS: Estudio transversal analítico, análisis de datos secundarios de la Primera Encuesta LGBTI de Perú. Se tomó como variable de interés a las personas que tuvieron alguna enfermedad durante los últimos doce meses y que tuvieron que recibir atención médica. Se calcularon razones de prevalencias crudas (RPc) y ajustadas (RPa), con intervalos de confianza al 95% (IC   95%), usando regresiones de Poisson con varianza robusta. Se desarrollaron tres modelos, ajustados a variables agrupadas en correspondencia con la orientación sexual, identidad de género e intersexualidad, respectivamente. RESULTADOS: El 55,4% fueron registrados como varones al nacer, la mediana de la edad fue 25 años (Rango intercuartil: 21-30). El 16% manifestó no haber buscado atención médica. Los tres modelos presentaron una asociación negativa respecto de padecer una enfermedad crónica, enfermedad infectocontagiosa, enfermedad mental y en quienes expresaban su orientación abiertamente. El no ser respetados por el género con el que se identificaban estuvo relacionado a no usar los servicios en el modelo 3. Los modelos 1 y 3, incluyeron una asociación positiva con no ser respetados con el género que se identifica. CONCLUSIÓN: Padecer de alguna enfermedad mental, una enfermedad infectocontagiosa y una enfermedad crónica además de no ser tratado con respeto según el género con el que se identifica son factores asociados a la no utilización de los servicios de salud.

Introduction: Enterobiasis is one of the main intestinal infections worldwide. Objective: Determine the factors associated to Enterobius vermicularis infection in children from two native Ese'Eja communities in Madre de Dios, Peru. Methods: An analytical cross-sectional study was conducted in February-March 2014 of 77 children aged 1-11 years. Enterobiasis diagnosis was based on Graham's test. Clinical manifestations were evaluated by a physician, whereas associated factors were determined through a survey applied to the parents of the children studied. Use was made of descriptive and analytical statistical analysis, and crude and adjusted prevalence ratios with a CI of 95 percent. A p value of 0.05 was considered significant. Results: Enterobiasis prevalence was 32.47 percent (25). The associated factors (PR and CI 95 percent) in the bivariate analysis were onychophagia 2.1 (1.1-3.9), finger sucking 5.4 (2.1-2.7), long nails 7 (2.6-18.6), exchanging clothes 2.3 (1.1-3.7), changing underwear 3.3 (1.8-5.9), wearing shoes 7 (2.6-18.4), playing with earth 6.9 (1.7-27.3), playing with pets 6.4 (2.1-19.7), handwashing before eating 7.9 (3.6-17.1), handwashing after eating 1.9 (1.7-3.66), six or more people in the household 3.9 (1.9-7.9), feces disposal in open areas 3.3 (1.7-6.2) and a lower socioeconomic level 2.6 (1.3-5.4). Multivariate analysis did not find any association. Conclusions: Enterobiasis prevalence is high in the population studied, and the risk factors are similar to the local antecedents.

Detection of Viral and Bacterial Respiratory Pathogens Identified by Molecular Methods in COVID-19 Hospitalized Patients and Its Impact on Mortality and Unfavorable Outcomes.

PURPOSE: The purpose of this study is to evaluate the frequency of viral and bacterial respiratory pathogens detected by molecular methods in sputum samples of patients hospitalized for COVID-19 and to evaluate its impact on mortality and unfavorable outcomes (in-hospital death or mechanical ventilation). PATIENTS AND METHODS: The prospective cohort included patients with diagnosis of COVID-19 hospitalized at Hospital Nacional Hipólito Unanue. Sociodemographic and clinical data were collected from clinical records. Sputum samples were analyzed with the Biofire Filmarray Pneumonia plus® respiratory panel. Crude and adjusted associations with unfavorable outcomes were evaluated using logistic regression models. RESULTS: Ninety-three patients who were able to collect sputum samples were recruited between September 8 and December 28, 2020. The median age was 61.7 years (IQR 52.3-69-8) and 66 (71%) were male. The most frequent symptoms were dyspnea, cough, fever, and general malaise found in 80 (86%), 76 (82%), 45 (48%), and 34 (37%) patients, respectively. Fifty-three percent of patients had comorbidities. Seventy-six (82%) patients received antibiotics prior to admission and 29 (31%) developed unfavorable outcome. Coinfection was evidenced in 38 (40.86%) cases. The most frequently found bacteria were Staphylococcus aureus, Streptococcus agalactiae, Haemophilus influenzae and Klebsiella pneumoniae in 11 (11.83%), 10 (10.75%), 10 (10.75%), and 8 (8.6%) cases, respectively. Streptococcus pneumoniae was found in one case (1.08%). We neither identify atypical bacteria nor influenza virus. No association was found between the presence of viral or bacterial microorganisms and development of unfavorable outcomes (OR 1.63; 95% CI 0.45-5.82). CONCLUSION: A high frequency of respiratory pathogens was detected by molecular methods in patients with COVID-19 pneumonia but were not associated with unfavorable outcomes. No atypical agents or influenza virus were found. The high use antibiotics before admission is a concern. Our data suggest that the use of drug therapy against atypical bacteria and viruses would not be justified in patients hospitalized for COVID-19.

METHOD: Study of diagnostic tests. There was a sample of 513 patients, 225 patients with a diagnosis of pre-eclampsia and 288 patients without such diagnosis were selected. The analysis of the data obtained was carried out in STATA v.14, obtaining the values of sensitivity, specificity, PPV and NPV. RESULTS: The ROC curve was analyzed obtaining an AUC of 0.91 (95% CI: 0.89 - 0.93), obtaining 187 points as the cut-off point for the best diagnostic performance, with a sensitivity of 81.33% and a specificity of 85.76%. CONCLUSIONS: The preeclampsia prediction nomogram has a good diagnostic performance for pregnant women attended at the Gynecology and Obstetrics service of the Dos de Mayo National Hospital.

Frecuencia de coinfección por patógenos respiratorios y su impacto en el pronóstico de pacientes con COVID-19 / Frequency of coinfection by respiratory pathogens and its impact on the prognosis of patients with COVID-19

Introducción: La coinfección entre otros microorganismos y el SARS-CoV-2, como virus, bacterias y hongos, es un factor importante en el manejo del COVID-19, el cual podría aumentar las dificultades en el diagnóstico, manejo, pronóstico, e incluso aumentar los síntomas y la mortalidad. Objetivos: El objetivo de la presente revisión es describir la evidencia científica publicada respecto a coinfección en pacientes con COVID-19. Métodos: Se llevó a cabo una búsqueda bibliográfica de estudios publicados en idioma español o inglés usando los buscadores de PubMed, The Cochrane Library y Google Scholar, se buscaron estudios publicados entre enero del 2020 hasta el 24 de enero del 2021. Resultados: Se incluyeron 25 artículos procedentes de diversos continentes (América, Asia y Europa). Todos los estudios contaron con pacientes con diagnóstico confirmado de COVID-19 sumado a alguna otra prueba que identifico alguna coinfección. Se identificaron estudios 18 estudios que mostraron coinfección bacteria, 17 estudios de coinfección viral y 5 estudios de coinfección fúngica. La prevalencia de coinfección mostro cifras extremadamente disimiles de acuerdo con la población estudiada y criterios diagnósticos. Conclusión: La presencia de coinfección parece ligarse a una mayor frecuencia de desenlaces desfavorables. Sin embargo, es importante desarrollar estudios latinoamericanos, dada la heterogeneidad en los estudios vista en los distintos países. Se deben desarrollar definiciones estandarizadas a fin de poder valorar el impacto de las coinfecciones en pacientes con diagnóstico de COVID-19.

Introduction: Co-infection between other microorganisms and SARS-CoV-2, such as viruses, bacteria and fungi, is an important factor in the management of COVID-19, which could increase the difficulties in diagnosis, management, prognosis, and even increase the mortality. Objectives: The objective of this review is to describe the published scientific evidence regarding coinfection in patients with COVID-19. Methods: A bibliographic search of studies published in Spanish or English was carried out using the PubMed, The Cochrane Library and Google Scholar search engines. Studies published between January 2020 and January 24, 2021 were assessed. Results: 25 articles from various continents (America, Asia and Europe) were included. All the studies had patients with a confirmed diagnosis of COVID-19 added to some other test that identified some co-infection. We identified 18 studies that showed bacterial coinfection, 17 studies of viral coinfection and 5 studies of fungal coinfection. The prevalence of coinfection showed extremely dissimilar figures according to the population studied and diagnostic criteria. Conclusions: The presence of coinfection seems to be linked to a higher frequency of unfavorable outcomes. However, it is important to develop Latin American studies, given the heterogeneity in the studies seen in different countries. Standardized definitions should be developed in order to be able to assess the impact of co-infections in patients with a diagnosis of COVID-19.
