Introduction. Hemophilia is a rare congenital bleeding disorder; which requires interdisciplinary, complex, and often expensive management. The objective of this clinical practice guideline (CPG) is to provide evidence-based clinical recommendations for the evaluation and management of patients with hemophilia in the Peruvian Social Security (EsSalud). Methods. A local elaboration group (GEG-Local) was established, conformed by specialists in hematology and methodologists. The GEG-Local formulated 8 clinical questions to be answered by this CPG. We searched for and selected hemophilia CPGs that answered the questions posed and obtained a score higher than 60% in domains 1 and 3 of the Appraisal of Guidelines for Research and Evaluation II (AGREE-II). During 2016, bibliographic searches were conducted in Pubmed, EMBASE and the Cochrane library, to update 7 clinical questions of the preselected CPG, and to answer a question de novo. In regular work meetings, the GEG-Local reviewed the evidence and formulated the recommendations and flowcharts using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. Finally, the CPG was approved with Resolution No. 32-IETSI-ESSALUD-2016. Results. This CPG addressed 8 clinical questions. Based on these questions, 22 recommendations were formulated (three strong recommendations and 19 weak recommendations) and four flowcharts. Conclusion. This article is the summary of the EsSalud CPG, in which the available scientific evidence on the diagnosis and treatment of hemophilia was assessed.

Introducción. La hemofilia es un trastorno hemorrágico congénito poco común que requiere un manejo interdisciplinario, complejo, y frecuentemente costoso. El objetivo de la presente guía de práctica clínica (GPC) es proveer recomendaciones clínicas basadas en evidencia para el diagnóstico y tratamiento de hemofilia en el seguro social del Perú (EsSalud). Métodos. Se conformó un grupo elaborador local (GEG-Local) conformado por especialistas en hematología y metodólogos. El GEG-Local formuló ocho preguntas clínicas a ser respondidas por la presente GPC. Se buscaron y seleccionaron GPC de hemofilia que respondieran a las preguntas planteadas y obtuvieran un puntaje mayor a 60% en los dominios uno y tres del instrumento Appraisal of Guidelines for Research and Evaluation II (AGREE-II). Durante el 2016 se realizaron búsquedas bibliográficas en Pubmed, EMBASE y biblioteca Cochrane, para actualizar siete preguntas clínicas de la GPC preseleccionada, y para responder una pregunta de novo. En reuniones de trabajo periódicas, el GEG-Local revisó la evidencia y formuló las recomendaciones y flujogramas usando la metodología Grading of commendations Assessment, Development, and Evaluation (GRADE). Finalmente, la GPC fue aprobada con Resolución N° 32-IETSI-ESSALUD-2016. Resultados. La presente GPC abordó ocho preguntas clínicas. En base a dichas preguntas se formularon 22 recomendaciones (tres recomendaciones fuertes y 19 recomendaciones condicionales) y cuatro flujogramas. Conclusión. Este artículo es el resumen de la GPC de EsSalud, en la cual se valoró la evidencia científica disponible sobre diagnóstico y tratamiento de hemofilia.

Introduction: To describe the scientific literature production in Peru about type 2 diabetes mellitus (DM) and diabetic nephropathy (DN). Methods: A non-systematic review of the scientific production about DM and DN in peruvian population and has been published in national and international medical journals until february 2015 was conducted. We used the databases Medline, Web of Science, Scopus, SciELO and Google Scholar. The results were divided a priori into 5 areas: Prevalence DM 2, clinical management of the diabetic patient, diagnosis of DN, risk factors for albuminuria, and early assessment of DN. Results: We found 22 items. The prevalence of DM varies depending on the definition and study population and was higher on the coast than in the highlands (4.3% vs. 2.1%). In public hospitals in Lima, 40% of diabetic patients have HbA1c> 7%. Likewise, the control of DM patients in Peru is poor compared with their Latin American counterparts. The "screening" of the NFD is uncommon, only 8.9% of patients have albuminuria in their assessments in hospitals nationwide. Modifiable factors associated with albuminuria in patients with DN were found such as glucose (OR 1.19 95% CI 1.05 to 1.34), hypertension (OR 0.48 95% CI 0.33 to 0.70) and stages of chronic kidney disease OR: 93 (p = 0.007). There are hospitals where nephrology care in patients with DN is mostly under emergency conditions. Conclusions: The results of these articles reflect that there are aspects in the screening and management of both diseases that can be improved and scarcity of studies on the subject in Peru.

Introducción: Describir la producción científica peruana que sobre diabetes mellitus 2 (DM) y nefropatía diabética (NFD) se ha escrito en la literatura médica. Material y métodos: Se realizó una revisión bibliográfica no sistemática de la producción científica que sobre DM y NFD en población peruana y que ha sido publicada en revistas médicas nacionales e internacionales hasta febrero de 2015. Se consultaron las bases de datos Medline, Web of Science, Scopus, SciELO y Google Scholar. Los resultados se dividieron a priori en cinco áreas temáticas: prevalencia de DM, manejo clínico de los pacientes diabéticos, diagnóstico de la NFD, factores de riesgo para albuminuria, y evaluación temprana de la NFD. Resultados: Se encontraron 22 artículos. La prevalencia de la DM varía dependiendo la definición y población estudiada siendo mayor en la costa que en la sierra (4,3% vs. 2,1%). El 40% de los pacientes diabéticos en hospitales públicos de Lima tiene HBA1C > 7%. Así mismo, el control de los pacientes DM en Perú es deficiente comparado con sus pares latinoamericanos. El "screening" de la NFD es infrecuente, solo 8,9% de los pacientes tiene albuminuria en sus evaluaciones en hospitales a nivel nacional. Se encontraron factores modificables asociados a la albuminuria en pacientes con NFD tales como glicemia (OR 1,19 IC 95%: 1,05-1,34), hipertensión arterial (OR 0,48 IC 95%: 0,33-0,70) y estadios de enfermedad renal crónica OR 1,93 (p=0.007). Existen hospitales donde la atención nefrológica en pacientes con NFD es mayormente en condiciones de emergencia. Conclusiones: Los resultados de estos artículos mostraron que existen aspectos perfectibles en el "screening" y manejo de ambas enfermedades así como escasez de estudios sobre el tema en Perú.

We evaluated the efficacy/effectiveness of community-based interventions to decrease neonatal mortality. A systematic review of randomized controlled trials, cluster randomized trials and cohort studies of interventions on pregnant women, neonates (up to 28 days after birth) or both was made. Thirty four studies were evaluated (n=844,989): 20 in pregnant women (n=406,172), 6 in neonates (n=24,994), and 8 in both (n=413,823). Risk of bias was generally low. There was heterogeneity among interventions. Interventions such as maternal health education and maternal and neonatal home care were associated to a decrease in neonatal mortality in half of the 6 studies of each group. Supplementation with multiple micronutrients, kangaroo mother care, and maternal supplementation with vitamin A did not decrease neonatal mortality. A few heterogeneous community-based interventions demonstrated a decrease in neonatal mortality.

Se evalúa la eficacia/efectividad de las intervenciones basadas en la comunidad, destinadas a disminuir la mortalidad neonatal. Se realizó una revisión sistemática de ensayos controlados aleatorizados, ensayos aleatorizados de comunidad y estudios de cohortes de intervenciones dirigidas a la mujer gestante, al neonato (hasta 28 días de nacido) o a ambos. Se evaluaron 34 estudios (n=844,989): 20 en mujeres gestantes (n=406,172); 6 en neonatos (n=24,994), y 8 en ambos grupos (n=413,823). El riesgo de sesgo fue generalmente bajo. Hubo heterogeneidad entre los tipos de intervenciones. Las intervenciones educación materna en salud y cuidado en casa de madres y neonatos estuvieron asociadas con disminución de mortalidad neonatal en la mitad de los seis estudios de cada grupo. La suplementación materna con multimicronutrientes, el cuidado de madre canguro y la suplementación materna prenatal con vitamina A no disminuyeron la mortalidad neonatal. Pocas intervenciones comunitarias heterogéneas han demostrado disminuir la mortalidad neonatal.

This cross-sectional study analyzed the association between poor quality of sleep and adherence to highly active antiretroviral therapy (HAART) in 389 Peruvian patients with HIV/AIDS. Poor quality of sleep was measured with the Pittsburgh Sleep Quality Index (PSQI) and adherence with the CEAT-VIH (Peruvian adaptation). A Poisson generalized linear model with robust standard errors was used to estimate prevalence ratios and 95%CI. A crude model showed that mild, moderate, and severe poor quality of sleep were associated with inadequate treatment adherence. In the adjusted model for variables associated in the bivariate analysis or variables theoretically associated with adherence, only moderate/severe poor quality of sleep remained associated (PR = 1.34, 95%CI: 1.17-1.54; and PR = 1.34, 95%CI: 1.16-1.57, respectively). The study concluded that moderate/severe poor quality of sleep was independently associated with adherence to HAART. Assessing quality of sleep may be helpful in the comprehensive evaluation of HIV patients.

Con el objetivo de evaluar si existe asociación entre la mala calidad de sueño y la adherencia al tratamiento antirretroviral de gran actividad (TARGA) en personas con infección por VIH/ SIDA; llevamos a cabo un estudio analítico de corte transversal que incluyó 389 pacientes peruanos en TARGA. La mala calidad de sueño fue medida con la Escala de Calidad de Sueño de Pittsburgh y la adherencia con el CEAT-VIH. Realizamos un modelo lineal generalizado de familia Poisson, con errores estándar robustos para estimar razones de prevalencia y su IC95%. A nivel crudo la mala calidad de sueño leve, moderada y severa se asoció a la adherencia inadecuada. Al ajustar por las variables asociadas en el análisis bivariado o por las variables teóricamente asociadas a la adherencia, sólo la mala calidad de sueño moderada/severa se mantuvo asociada (RP = 1,34; IC95%: 1,17-1,54 y RP = 1,34; IC95%: 1,16-1,57; respectivamente). Se concluye que la mala calidad de sueño moderada/severa se asocia de manera independiente con la adherencia al TARGA. La evaluación de la calidad de sueño podría por ende ser útil en la valoración integral de los pacientes con VIH.

A fim de avaliar se a associação entre a má qualidade do sono e adesão à terapia antirretroviral (TARV) em pessoas com infecção pelo HIV/AIDS, realizamos um estudo analítico de corte transversal que incluiu 389 pacientes peruanos em TARV. A má qualidade do sono foi medida com a escala Índice de Qualidade de Sono de Pittsburgh (IQSP) e a aderência com o CEAT- (adaptação peruana). Foi realizado um modelo linear generalizado da família Poisson com padrão de erros robustos, para estimar as razões de prevalência e IC95%. No nível cru, a má qualidade do sono leve, moderada e grave foram associadas com adesão inadequada. Quando fizemos o ajuste para as variáveis associadas na análise bivariada ou variáveis teoricamente associadas à adesão, somente a má qualidade moderada/grave manteve-se associada (RP = 1,34; IC95%: 1,17-1,54 e RP = 1,34; IC95%: 1,16-1,57; respectivamente). Concluímos que a má qualidade do sono moderada/grave está independentemente associada com a adesão a TARV. Avaliar a qualidade do sono pode ser útil na avaliação global do paciente com HIV.

Background: Failing to attend a monthly session within a scheme of conventional dialysis may increase mortality by 30%. Objectives: To describe the frequency and perceived causes of non-adherence to dialysis in a Peruvian national reference public hospital. Design: Descriptive study. Setting: Nephrology department, Hospital Nacional 2 de Mayo, Lima, Peru. Participants: Patients with more than one year on dialysis. Interventions: The number of absences to appointed sessions was determined and a validated questionnaire was used to describe perceptions regarding the causes of absences. Main outcomes measures: Low adherence to dialysis defined as patients with more than one absence per month or more than 12 absences between July 2012 and July 2013. Results: The study included 54 patients, of which 27 were male. Average age was 57 ± 16.4 years and average time on dialysis was 40.6 ± 11.5 months. Only 7 patients had higher education. There were 504 absences (5.45%). The second day of the weekly schedule was the day with more absences (292), followed by the third day (145). Overall 13 patients showed low adherence. Main causes of absence reported included a remote residence (6/13), feeling good (6/13), and insufficient financial resources to cover transportation costs (5/13). Conclusions: A quarter of patients had low adherence, and main factors were distance to health facility and wellbeing self -perception.

Introducción: La ausencia a una sesión mensual en un esquema de diálisis convencional puede incrementar la mortalidad en 30%.Objetivos: Describir la frecuencia y la percepción de las causas de falta de adherencia a diálisis en una población prevalente de un hospital público de referencia nacional en Perú. Diseño: Estudio descriptivo. Institución: Servicio de Nefrología, Hospital Nacional 2 de Mayo, Lima, Perú. Participantes: Pacientes con más de un año en diálisis Intervenciones: Se determinó el número de faltas y se aplicó un cuestionario para describir su percepción respecto a las causas de las faltas, validado por juicio de expertos. Principales medidas de resultados: Baja adherencia a diálisis definida como: pacientes con más de una falta al mes o más de 12 faltas, entre julio de 2012 y julio de 2013. Resultados: Se incluyó 54 pacientes, 27 eran varones, con una edad y tiempo de diálisis promedio de 57 ± 16,4 años y 40,6 ±11,5 meses, respectivamente; 7/54 pacientes tenían educación superior. Hubo 504 faltas (5,45%). El segundo día de la programación semanal fue el día con mayor frecuencia de faltas (292), seguido del tercer día (145); 13/54 tuvieron baja adherencia. Las principales causas reportadas fueron: una residencia alejada (6/13), la sensación de bienestar (6/13), el contar con escasos recursos económicos para solventar el traslado (5/13). Conclusiones: Uno de cada cuatro pacientes tuvo baja adherencia. El residir lejos o que se sintiera bien fueron las principales causas de la baja adherencia.

Vaccination is one of the most important public health interventions in the reduction childhood morbidity and mortality. Thimerosal is an organic mercury compound used as preservante in multi-dose vials. Often in Peru, there are waves of controversy about the safety of this type of vaccines, mainly arguing that there is an association between them and autism. As a result of these controversies, there have been some voices asking for laws banning thimerosal-containing vaccines, which would have a large impact in costs and the logistic aspects of the public vaccination programs. The aim of this article is to review the literature for the main controversies about thimerosal in vaccines and its supposed association to autism. We made an historical review about these controversies given the available scientific evidence and the statements from important international organizations. We concluded that the current available evidence do not support an association between thimerosal and childhood neurodevelopmental disorders, such as autism.

La vacunación es una de las medidas de mayor impacto en la salud pública para la reducción de la morbimortalidad infantil. El timerosal es un compuesto orgánico del mercurio utilizado como preservante de los frascos multidosis. Eventualmente, en el Perú, surgen olas de controversia acerca de la seguridad de estas vacunas, asociándolas especialmente con el autismo. Como resultado de estas controversias, se han propuesto, incluso, leyes que prohíben este tipo de vacunas, lo que tendría un importante impacto en los costos y en los aspectos logísticos de la estrategia nacional de vacunación. En este artículo se revisa la literatura sobre las principales controversias acerca de las vacunas que contienen timerosal y su supuesta asociación con el autismo. Se realiza una aproximación histórica sobre estas controversias, se hace una actualización de la evidencia científica disponible al momento, y se revisa la posición de los organismos internacionales más importantes con respecto a este tema. Se concluye que la evidencia científica no apoya la noción que exista una asociación entre el uso del timerosal en las vacunas con los trastornos del espectro autista en niños.

Existe informação limitada e contraditória sobre o prognóstico da co-infecção pelo Vírus da Imunodeficiência Humana Tipo 1 (HIV-1) e Vírus Linfotrópico de Células T Humanas Tipo I (HTLV-I). Nosso objetivo foi estimar o efeito da infecção pelo HTLV-I na mortalidade de pacientes infectados pelo HIV-1 em Centro de Referência de HIV no Peru. Trata-se de uma coorte retrospectiva de pacientes infectados pelo HIV, expostos ou não expostos ao HTLV-I. Os pacientes expostos tiveram resultados positivos no Western Blot (WB) para ambos retrovírus. Os pacientes não expostos tiveram resultados positivos para o HIV-1 e pelo menos um teste de EIA negativo para o HTLV-I. Esses pacientes foram selecionados entre aqueles que entraram no nosso Programa imediatamente antes ou depois de cada paciente exposto, no período de janeiro de 1990 a junho de 2004. O tempo de sobrevida foi considerado entre o diagnóstico da exposição ao HTLV-I e a morte. As variáveis de confusão foram: idade, gênero, estágio clínico basal da infecção pelo HIV-1, contagem basal de células CD4, e terapia anti-retroviral. Estudamos 50 pacientes expostos e 100 não expostos. Os pacientes expostos tiveram menor sobrevida quando comparados aos não expostos [mediana de sobrevida: 47 meses (95% IC: 17-77) versus 85 meses (70-100), p não ajustado < 0.06]. Os pacientes expostos tiveram maior risco de morte quando comparados aos não expostos (HIV-1/HTLV-I (24/50 [48%]) versus HIV-1 só (37/100 [37%]) p univariado = 0.2). A exposição ao HTLV-I não foi associada a maior risco de morte na análise ajustada: HR: 1.2 (0.4-3.5). O estágio clínico da infecção pelo HIV-1 e a ausência de terapia anti-retroviral foram associados a maior risco de morte. Em conclusão, a infecção pelo HTLV-I não foi associada a maior risco de morte em pacientes peruanos infectados pelo HIV-1. A infecção avançada pelo HIV-1 e a falta de terapia anti-retroviral podem explicar o excesso de mortalidade nesta população.

Limited and contradictory information exists regarding the prognosis of HIV/HTLV-I co-infection. Our goal was to estimate the effect of HTLV-I infection on mortality in HIV-infected patients at a HIV reference center in Peru. We studied a retrospective cohort of HIV-infected patients, who were exposed or unexposed to HTLV-I. Exposed patients were Western Blot (WB) positive for both retroviruses. Unexposed patients were WB positive for HIV, and had least one negative EIA for HTLV-I. These were selected among patients who entered our Program immediately before and after each exposed patient, between January 1990 and June 2004. Survival time was considered between the diagnosis of exposure to HTLV-I and death or censoring. Confounding variables were age, gender, baseline HIV clinical stage, baseline CD4+ T cell count, and antiretroviral therapy. We studied 50 exposed, and 100 unexposed patients. Exposed patients had a shorter survival compared to unexposed patients [median survival: 47 months (95% CI: 17-77) vs. 85 months (95% CI: 70-100), unadjusted p = 0.06]. Exposed patients had a higher rate of mortality compared to unexposed patients (HIV/HTLV-I (24/50 [48%]) vs. HIV only (37/100 [37%]), univariable p = 0.2]. HTLV-I exposure was not associated to a higher risk of death in the adjusted analysis: HR: 1.2 (0.4-3.5). AIDS clinical stage and lack of antiretroviral therapy were associated to a higher risk of dying. In conclusions, HTLV-I infection was not associated with a higher risk of death in Peruvian HIV-infected patients. Advanced HIV infection and lack of antiretroviral therapy may explain the excess of mortality in this population.

Objectives: To describe perceptions and working conditions in persons who had malaria. Material and methods: The study was performed between February 1999 and January 2000 in El Algarrobo and Casa Grande villages (Piura), Iquitos, Huamba (Huarmey), and Cieneguilla (Lima). The sample included 67 persons. Each one underwent an indepth interview. 44 cases were diagnosed in Piura and Huarmey, and the remaining cases were from Iquitos and Cieneguilla. Results: It was found that persons who had malaria were working in farming, particularly growing rice, lemon, banana, yucca, and corn; they did not use appropriate dressing, and they also did not receive any working material nor information regarding preventive measures against malaria. Jobs were temporary and working time took almost all day, and their average daily income was three US dollars. In many cases, as it was the case with timber workers, working hours extended until night time. Generally speaking, interviewed persons had a good relationship with their fellow workers, as well as with their supervisers. In most cases, interviewed persons attributed their disease to their jobs. In Piura, Huarmey, and Cieneguilla, farming and handcraft making were important occupations, particularly mat manufacturing; in Iquitos, important activities were being fishermen and timber worker. Conclusions: Disease perception and working conditions in persons who had malaria in the study areas are not good, so it is suggested to solve these problems in order to improve their working conditions.

Objetivos: Describir percepciones y condiciones de trabajo de personas que tuvieron malaria. Materiales y métodos: El estudio se realizó entre febrero de 1999 y enero del año 2000 en los caseríos El Algarrobo y Casa Grande (Piura), Iquitos, Huamba (Huarmey) y Cieneguilla (Lima). La muestra estuvo conformada por 67 personas, a cada una de las cuales se le aplicó una entrevista en profundidad; 44 fueron casos diagnosticados en Piura y Huarmey, siendo el resto de Iquitos y Cieneguilla. Resultados: Se encontró que las personas que tuvieron malaria estaban dedicadas a la agricultura, particularmente sembrado de arroz, limón, algodón, plátano, yuca y maíz; no recibían vestimenta apropiada, ni materiales de trabajo e información sobre medidas preventivas contra el paludismo. El trabajo era temporal y durante casi todo el día, percibían un salario promedio de alrededor de tres dólares americanos por día. En muchos casos, como el de los madereros, el trabajo también se extendía a la noche. En general existía armonía entre los compañeros de trabajo y buenas relaciones con el jefe, patrón o capataz. En su mayoría, los pacientes atribuyeron la enfermedad a su trabajo. En Piura, Huarmey y Cieneguilla la agricultura y la artesanía fueron ocupaciones importantes, particularmente confección de esteras; en Iquitos las ocupaciones importantes fueron pescador y maderero. Conclusiones: Las percepciones y condiciones de trabajo de las personas que han tenido malaria en las zonas de estudio no son buenas, sugiriéndose dar atención al problema para mejorar sus condiciones.

A epidemia da infecção pelo vírus da imunodeficiência humana (HIV) aumentou a prevalência, multiresistência e formas disseminadas da tuberculose. O acometimento neurológico da tuberculose apresenta elevada morbidade e mortalidade, classificando-se em formas difusas (meningite) e localizadas (tuberculoma e abscesso). Relatamos três casos de tuberculomas cerebrais em pacientes com AIDS: um deles com diagnóstico definitivo, confirmado com histopatologia e dois com diagnóstico provável, baseado em informação clínica, radiológica, isolamento de Mycobaterium tuberculosis fora do sistema nervoso central e adequada resposta ao tratamento tuberculostático. Discutimos também aspectos diagnósticos, terapêuticos e prognósticos dos tuberculomas, enfatizando suas diferenças com os abscesos tuberculosos cerebrais. Apesar de serem relatados de forma infreqüente, os tuberculomas devem sempre ser considerados no diagnóstico diferencial das lesões expansivas cerebrais em pacientes com AIDS.

The human immunodeficiency virus (HIV) infection epidemics increased the prevalence, multi-drug resistance and disseminated forms of tuberculosis. The central nervous system (CNS) tuberculosis has high mortality and morbidity, and it is usually divided into diffuse (meningitis) and localized (tuberculoma and abscess) forms. We report three cases of cerebral tuberculomas in AIDS patients: one with definitive diagnosis, confirmed with histopathology, and two with probable diagnosis, based on clinical information, radiological images, Mycobaterium tuberculosis isolation out of the CNS and adequate response to antituberculous treatment. Further, we discuss diagnostic, therapeutic and prognostic issues of tuberculomas, with emphasis in the distinction from cerebral tuberculous abscesses. Despite of their infrequent presentation, tuberculomas should be considered in the differential diagnosis of cerebral expansive lesions in patients with AIDS.
