Estudio de prevalencia, conocimiento y control de la hipertensión arterial en barrios vulnerables de Argentina / Prevalence, knowledge and control of arterial hypertension in vulnerable neighborhoods of Argentina: A Cross-sectional Study

Introducción: La hipertensión arterial (HTA) representa el principal factor de riesgo individual, con mayor carga a nivel mundial de enfermedades cardiovasculares (ECV). En nuestro país, algunos trabajos epidemiológicos han mostrado marcadas diferencias en las prevalencias de estos factores de riesgo de acuerdo con la población evaluada. Sin embargo, no hay estudios epidemiológicos de evaluación de factores de riesgo cardiovascular exclusivos referentes a barrios vulnerables con muy bajos recursos económicos, socioculturales y poca accesibilidad a los sistemas de salud. Materiales y métodos: Estudio observacional de corte transversal multicéntrico en habitantes de comunas vulnerables de muy bajos recursos, como asentamientos populares y barrios carenciados con muestreo aleatorizado simple de casas. Se realizaron tomas de presión arterial (PA), medidas antropométricas, así como cuestionarios epidemiológicos, económicos y socioculturales. Se describen los hallazgos: prevalencia, conocimiento y control de la PA en las distintas regiones. Se efectuó una regresión logística para determinar las variables independientes a los resultados principales. Resultados: Se analizaron 989 participantes. La prevalencia de HTA global fue de 48,2%. Un total de 82% tenía un índice de masa corporal (IMC) >25 kg/m2. De estos pacientes, 45,3% tenían menos de seis años de educación. Este último aspecto se asoció a mayor prevalencia de HTA de forma independiente. De los hipertensos, 44% desconocían su padecimiento y solo en 17,2% estaba controlado, asociándose esto a tener obra social (OS) y mayor nivel educativo. Únicamente 24% estaban bajo tratamiento combinado. Conclusión: La prevalencia de HTA en barrios vulnerables es elevada, superando a la de otros estratos sociales con niveles de conocimiento, tratamiento y control de la HTA bajos, similar a otras poblaciones. Se detectó un uso insuficiente de la terapia combinada.

Introduction: Hypertension (HTN) represents the primary individual risk factor, contributing significantly to the global burden of cardiovascular diseases (CVD). In our country, epidemiological research has highlighted substantial variations in the prevalence of these risk factors across different populations. However, there is a lack of epidemiological studies assessing exclusive cardiovascular risk factors within vulnerable neighborhoods characterized by extremely limited economic resources, sociocultural challenges, and inadequate healthcare access. Methods: A multicenter cross-sectional observational study was conducted among individuals residing in economically deprived and marginalized communities, including informal settlements and underprivileged neighborhoods. Simple random sampling of households was employed. Blood pressure measurements, anthropometric assessments, and epidemiological, economic, and sociocultural questionnaires were administered. Results encompass prevalence rates, awareness levels, and blood pressure control across diverse regions. Logistic regression was utilized to identify independent variables influencing primary outcomes. Results: A total of 989 participants were analyzed. The overall prevalence of hypertension was 48.2%. About 82% had a body mass index (BMI) >25. Approximately 45.3% had less than 6 years of formal education. Independent association was established between education levels below 6 years and higher hypertension prevalence Among hypertensive individuals, 44% were unaware of their condition, with only 17.2% achieving control, correlated with having health insurance and a higher educational background. Merely 24% were receiving combined therapy. Conclusion: The prevalence of hypertension within vulnerable neighborhoods is alarmingly high, surpassing rates in other social strata. Knowledge, treatment, and control levels of hypertension are suboptimal, comparable to other populations... (AU)

Renin–angiotensin–aldosterone system blockers effect in chronic kidney disease progression in hypertensive elderly patients without proteinuria: PROERCAN trial / Efecto de los bloqueantes del sistema renina-angiotensina-aldosterona en la progresión de enfermedad renal crónica en pacientes hipertensos añosos sin proteinuria: ensayo clínico Progresión de Enfermedad Renal Crónica en Ancianos

Introduction: Evidence about nefroprotective effect with RAAS blockers in elderly patients with chronic kidney disease (CKD) without proteinuria is lacking. The primary outcome of our study is to evaluate the impact of RAAS blockers in CKD progression in elderly patients without proteinuria. Materials and methods: Multicenter open-label, randomized controlled clinical trial including patients over 65 year-old with hypertension and CKD stages 3–4 without proteinuria. Patients were randomized in a 1:1 ratio to either receive RAAS blockers or other antihypertensive drugs and were followed up for three years. Primary outcome is estimated glomerular filtration rate (eGFR) decline at 3 years. Secondary outcome measures include BP control, renal and cardiovascular events and mortality. Results: 88 patients were included with a mean age of 77.9±6.1 years and a follow up period of 3 years: 40 were randomized to RAAS group and 48 to standard treatment. Ethiology of CKD was: 53 vascular, 16 interstitial and 19 of unknown ethiology. In the RAAS group eGFR slope during follow up was −4.3±1.1ml/min, whereas in the standard treatment group an increase on eGFR was observed after 3 years (+4.6±0.4ml/min), p=0.024. We found no differences in blood pressure control, number of antihypertensive drugs, albuminuria, potassium serum levels, incidence of cardiovascular events nor mortality during the follow up period. Conclusions: In elderly patients without diabetes nor cardiopathy and with non proteinuric CKD the use of RAAS blockers does not show a reduction in CKD progression.

Introducción: Actualmente no existe suficiente evidencia sobre el efecto nefroprotector de los bloqueantes del sistema renina-angiotensina-aldosterona (BSRAA) en pacientes añosos con enfermedad renal crónica (ERC) sin proteinuria y sin cardiopatía. El objetivo es evaluar el efecto de los BSRAA en la progresión de la ERC en este grupo poblacional. Métodos: Se trata de un estudio prospectivo, aleatorizado, que compara la eficacia de los BSRAA vs. otros tratamientos antihipertensivos en la progresión renal en personas mayores de 65 años con ERC estadios 3 y 4 e índice albúmina/creatinina<30mg/g. Aleatorización 1:1 BSRAA o tratamiento antihipertensivo estándar. Se recogieron cifras tensionales y parámetros analíticos de un año previo a la aleatorización y durante el seguimiento. Resultados: Se incluyeron 88 pacientes seguidos durante tres años con edad media de 77,9±6,1 años. De estos, se aleatorizaron 40 al grupo BSRAA y 48 al estándar. La etiología de ERC fue: 53 vascular, 16 intersticial y 19 no filiada. En el primer grupo se observó una progresión de la ERC con una caída del filtrado glomerular estimado (FGe) de -4,3±1,1mL/min, mientras que en el grupo estándar un aumento del FGe durante el seguimiento de 4,6±0,4mL/min, p=0,024. No se apreciaron diferencias entre ambos en el control tensional, el número de antihipertensivos, la albuminuria, los niveles de potasio, la incidencia de eventos cardiovasculares ni la mortalidad durante el seguimiento. Conclusiones: En pacientes añosos no diabéticos con ERC no proteinúrica y sin cardiopatía el uso de BSRAA no añade beneficio en la progresión de la ERC.

Monitorización ambulatoria de la presión arterial en adultos y población pediátrica. Una revisión narrativa / Ambulatory blood pressure monitoring, adult and pediatric population. A narrative review

La hipertensión arterial (HTA) se ha convertido en un factor de riesgo central para el desarrollo de enfermedades cardiovasculares (CV), lo que subraya la importancia de su diagnóstico preciso. Numerosos estudios han establecido una estrecha relación entre los valores elevados de la presión arterial sistólica (PAS) y diastólica (PAD) y un incremento en el riesgo de padecer algún evento cardiovascular (ECV). Tradicionalmente, las mediciones de la presión arterial (PA) realizadas en entornos clínicos han sido el principal método para diagnosticar y evaluar la HTA. No obstante, en los últimos años, se ha reconocido que las mediciones de la PA obtenidas fuera del ambiente clínico, mediante la automedida de la presión arterial (AMPA) y la monitorización ambulatoria de la presión arterial (MAPA), ofrecen una perspectiva más realista de la vida cotidiana de los pacientes y, por lo tanto, brindan resultados más fiables. Dada la evolución de los dispositivos médicos, los criterios diagnósticos y la creciente relevancia de componentes de la MAPA en la predicción de ECV, se requiere una actualización integral que sea práctica para la clínica. Esta revisión tiene como objetivo proporcionar una actualización de la MAPA, enfocándose en su importancia en la evaluación de la HTA. Además, se analizarán los umbrales diagnósticos, los distintos fenotipos según el ciclo circadiano y las recomendaciones en diferentes poblaciones, asimismo, se ofrecerán sugerencias concretas para la implementación efectiva de la MAPA en la práctica clínica, lo que permitirá a los profesionales de la salud tomar decisiones fundamentadas y mejorar la atención de sus pacientes.(AU)

Hypertension has become a central risk factor for the development of cardiovascular disease, underscoring the importance of its accurate diagnosis. Numerous studies have established a close relationship between elevated systolic (SBP) and diastolic (DBP) blood pressure and an increased risk of cardiovascular event (CVE). Traditionally, blood pressure (BP) measurements performed in clinical settings have been the main method for diagnosing and assessing hypertension. However, in recent years, it has been recognized that BP measurements obtained outside the clinical setting, using self-monitoring blood pressure (SMBP) and ambulatory blood pressure monitoring (ABPM), offer a more realistic perspective of patients’ daily lives and therefore provide more reliable results. Given the evolution of medical devices, diagnostic criteria, and the increasing relevance of certain components of ABPM in the prediction of adverse cardiovascular outcomes, a comprehensive update that is practical for daily clinical practice is required. The main objective of this article is to provide an updated review of ABPM, focusing on its importance in the evaluation of hypertension and its impact on public health in Colombia. In addition, it will discuss the implications of changes in diagnostic thresholds and provide concrete recommendations for the effective implementation of ABPM in clinical practice, allowing health professionals to make informed decisions and improve the care of their patients.(AU)

Hypertensive states of pregnancyEstados hipertensivos del embarazo / Estados hipertensivos del embarazo

Hypertensive disorders in pregnancy (HDP) remain a leading cause of pregnancy-related maternal and foetal morbidity and mortality worldwide, including chronic hypertension, gestational hypertension, and pre-eclampsia. Affected women and newborns also have an increased risk of cardiovascular disease later in life, independent of traditional cardiovascular disease risks. Despite these risks, recommendations for optimal diagnosis and treatment have changed little in recent decades, probably due to fear of the foetal repercussions of decreased blood pressure and possible drug toxicity. In this document we review the diagnostic criteria and classification of (HDP), as well as important aspects regarding pathophysiology and early detection that allows early identification of women at risk, with the aim of preventing both immediate and long-term consequences. Prophylactic treatment with aspirin is also reviewed early and a therapeutic approach is carried out that involves close maternal and foetal monitoring, and if necessary, the use of safe drugs in each situation. This review aims to provide an updated vision for the prevention, diagnosis, and treatment of HDP that is useful in our usual clinical practice.(AU)

Los estados hipertensivos del embarazo (EHE) siguen siendo una de las principales causas de morbilidad y mortalidad materna y fetal relacionada con el embarazo en todo el mundo, incluyen la hipertensión crónica, la hipertensión gestacional y la preeclampsia. Las mujeres afectadas y los recién nacidos también tienen un mayor riesgo de sufrir enfermedades cardiovasculares en el futuro, independientemente de los riesgos tradicionales de la enfermedad cardiovascular. A pesar de estos riesgos, las recomendaciones para un diagnóstico y un tratamiento óptimo han cambiado poco en las últimas décadas, probablemente por el miedo a las repercusiones fetales de la disminución de la presión arterial y la posible toxicidad farmacológica. En ese documento revisamos los criterios diagnósticos y la clasificación de los EHE, así como aspectos importantes en cuanto a fisiopatología y la detección temprana que permita la identificación precoz de las mujeres en riesgo, con el objetivo de prevenir tanto las secuelas inmediatas como a largo plazo. También se revisa el tratamiento profiláctico con aspirina de forma precoz y se realiza una aproximación terapéutica que implica una estrecha vigilancia materna y fetal, y si es necesario, el uso de fármacos seguros en cada situación. Esta revisión pretende dar una visión actualizada para la prevención, diagnóstico y tratamiento de los EHE que sea de utilidad en nuestra práctica clínica habitual.(AU)

Emergencia hipertensiva como debut de síndrome de Cushing paraneoplásico / Hypertensive Emergency as the Debut of Paraneoplastic Cushing Syndrome

Presentamos el caso de un paciente con antecedentes de hipertensión arterial vasculorrenal tratada un año antes, que acude a urgencias por emergencia hipertensiva (HTA) y disnea. Descartada primera sospecha de reestenosis de arteria renal con angiografía por tomografía computarizada (angioTC), se completa el estudio confirmándose diagnóstico de cáncer de pulmón mediante prueba de imagen y anatomía patológica. En el estudio de hipertensión se detecta elevación de hormona adrenocorticótropa (ACTH), hipercortisolismo y datos analíticos de hiperaldosteronismo. Con el diagnóstico final de síndrome de Cushing secundario a producción ectópica de ACTH se inicia tratamiento médico, sin llegar a recibir nada más por fallecimiento del paciente a los pocos días.(AU)

We present the case of a patient with a history of renal-vascular hypertension treated with stent one year previously, who attended the emergency room due to hypertensive emergency and dyspnea. Once the first suspicion of renal artery restenosis was ruled out with CT angiography, the study was completed, confirming the diagnosis of lung cancer through imaging and pathological anatomy. In the hormonal study, elevation of ACTH, hypercortisolism and analytical data of hyperaldosteronism were detected. With the final diagnosis of Cushing's syndrome secondary to ectopic production of ACTH, medical treatment was started, without being able to receive anything else due to the death of the patient after a few days.(AU)

[Consequence of hypertensive disorders during pregnancy (THE) on women's cardiovascular health]. / Consecuencia de los trastornos hipertensivos durante el embarazo (THE) sobre la salud cardiovascular de la mujer.

Patients with hypertensive disorders of pregnancy (HDP) are at increased risk of maternal-fetal complications and represent the third leading cause of maternal mortality. To date, it is known that women experiencing this condition during pregnancy have a higher future risk of cardiovascular events (CVD). Our objective was to report the incidence of new-onset hypertension in the postpartum period. We conducted a cohort study in high-risk pregnant patients who underwent ambulatory blood pressure monitoring (ABPM) between weeks 20-30. Patients were categorized as normotensive (NT) or gestational hypertensive (GH), excluding those with chronic hypertension, and were followed until the end of pregnancy with a postpartum assessment after 3months. Patients with HDP (39%) had a higher incidence of preeclampsia and newborns with low birth weight and preterm birth. A total of 177 pregnant women were analyzed for the primary outcome. Among those with GH, 33.3% vs 17.2% of NT (P=.014) reported new-onset hypertension. The odds ratio for developing new-onset hypertension was 2.3 (95%CI: 1.20-4.77), for those with GH. In conclusion, pregnant patients with GH assessed by ABPM between 20-30weeks are at higher risk of developing new-onset hypertension in the postpartum period, emphasizing the need for closer monitoring and control to prevent future cardiovascular complications.

Assessing levels of uric acid and other cardiovascular markers in prehypertensive and hypertensive adults.

INTRODUCTION: Although some studies have reported the association between uric acid (UA) and hypertension, evidence on prehypertension is still lacking. Therefore, the objective of this study was to determine the levels of UA and other cardiovascular markers among prehypertensive and hypertensive patients and assess their risk for developing arterial hypertension. METHODS: 157 individuals were recruited: 67 normotensive, 23 pre-hypertensive and 67 hypertensive. Blood samples were collected to measure biochemical parameters and anthropometric measurements and blood pressure were evaluated. We calculated the product of lipid accumulation and the visceral adiposity index to assess cardiovascular risk. RESULTS: Our data showed an increase in UA levels in normotensives (4.9±1.3mg/dL), prehypertensives (5.2±1.3mg/dL) and hypertensives (5.9±1.6mg/dL) (p=0.004). We found a higher frequency of hyperuricemia in the hypertensive group (34.3%) than in the normotensive group (13.4%, p<0.05). Hypertensive volunteers had lower levels of HDL-C (p=0.004 and p=0.003) and higher body mass indexes (p<0.001 and p=0.007), glucose (p<0.001 and p=0.033), triglycerides (p=0.001 and p=0.005), visceral adiposity index (p<0.001 and p=0.002) and lipid accumulation product (p<0.001 and p=0.007) than normotensive and prehypertensive participants. We also observed that individuals with UA≥6.2mg/dL had an increased risk of hypertension of 4.77 (p=0.003) compared to individuals with levels≤4.3mg/dL. CONCLUSION: Our results showed that UA is associated with increased blood pressure and unfavorable changes in anthropometric and biochemical parameters, which represent risk factors for hypertension and cardiovascular diseases.

Numerical values and impact of hypertension in Spain.

In Spain, 33% of adults aged 30 to 79 years (10 million) were hypertensive in 2019. Among them, 68% were diagnosed, 57% received drug therapy, and effective therapeutic coverage (control) reached 33%. Both diagnosis and control show geographical and social disparities. Approximately 46 000 cardiovascular deaths per year are attributable to hypertension. In recent decades, the control of hypertension has increased, due to improvements in lifestyle measures and increased use of polytherapy, coinciding with a reduction in stroke mortality. There are several modifiable determinants of the lack of hypertension control: a) white-coat phenomenon affects 22% to 33% of treated individuals, partly due to the limited availability of ambulatory blood pressure monitoring (ABPM) (49%) and self-measured BP (SMBP) (78%); b) inadequate patient adherence to medication and healthy lifestyles (weight loss, the most effective measure, is the least used, ≈40%); and c) insufficient use of polytherapy (≈55%). The remaining challenges include: a) technological aspects, such as measuring BP with more accurate techniques (ABPM, SMBP) and using cardiovascular-risk estimation tools (eg, SCORE); b) clinical challenges, such as reducing therapeutic inertia (≈59%), involving patients in their own management (medication adherence, ≈62%) and effectively implementing clinical guidelines); and c) public health challenges, such as reducing the burden of obesity (≈24%), monitoring progress with updated surveys, and setting national BP control targets.

[The role of nursing in right heart catheterization. Advantages from peripheral venous access]. / Papel de enfermería en el cateterismo cardiaco derecho. Ventajas del acceso venoso periférico.

INTRODUCTION: Pulmonary hypertension (PH) is a serious disease that requires early diagnosis to achieve a better patient prognosis. Right heart catheterization (RHC) has become the main diagnostic test for this disease, measuring the pressures from the right heart chambers invasively, using a catheter placed through venous access. Nursing performance has an important role in RHC through peripheral venous access due to its well-done skills for canalization and knowledge about the management and care of these accesses. RHC performed through peripheral venous access provide advantages over those performed through central venous access. OBJECTIVE: To analyze the benefits from RHC through peripheral venous access compared to those performed through central venous access, as well as highlighting the role of nursing during this type of procedures. METHOD: A retrospective, descriptive, and observational study was performed for patients who underwent RHC in our center between January 2019 to January 2023. We analyzed clinical characteristics, access, fluoroscopy parameters, periprocedural complications, and hospital admissions. RESULT: A total of 115 patients were included. The average age was 65±12 years, with 58.1% of females. Risk stratification of PH was the reason for conducting RHC in 82.9%. The anterocubital veins became the main approach (72.2%), performed by hemodynamics nurses, while the central venous ones composed the rest (27.8%), which were done by cardiology specialized doctors. We observed a significant reduction in radiation dose in RHC via anterocubital route compared to central venous access (4.4Gycm2 vs 12.5Gycm2 [IQR: 4.5]; P<.001), and it does also in fluoroscopy times (2.3minutes vs 4.6minutes [IQR: 2.6]; P<.001). No complications were recorded, independently of the approach. Patients who underwent a scheduled catheterization were discharged more frequently on the same day of the procedure whether a peripheral approach was performed (77.2%, 44 of 57 patients), in comparison with the central one (28.6%) (P=.001). CONCLUSIONS: The RHC is an essential tool for the diagnosis of PH, achieving nursing such an important role for those performed by peripheral venous access. Peripheral venous access provides benefits and advantages like the reduction of radiation exposure and scan times, reduced hospital stay. All this could bring greater comfort, safety and better quality of care to the patient.

Ambulatory blood pressure monitoring. Current status and future perspectives. / Monitorización ambulatoria de la presión arterial. Situación actual y perspectivas futuras.

Ambulatory Blood Pressure Monitoring (ABPM) is considered the best method for obtaining a reliable estimation of the true blood pressure. Average values obtained during the whole 24-hour period, or during daytime and nighttime periods are better correlated with the risk of mortality and cardiovascular disease compared to clinic or office blood pressure. Indeed, nighttime blood pressure, a measure only obtained through ABPM, is the most powerful risk predictor. ABPM is complementary to clinic blood pressure measurement and allows the definition of blood pressure phenotypes, such as "white-coat or masked hypertension, when clinic and ABPM measurements show discrepancy in normal values. Additional potentially relevant features include blood pressure variability, such as nocturnal blood pressure decline, morning surge or short-term variability, as determined by standard deviation or the coefficient of variation.

Can catheter-based renal denervation reduce frequency of hospitalization in patients who have resistant hypertension and heart failure with reduced ejection fraction?

Hypertension is one of the most powerful and modifiable risk factors for the development, progression and even decompensation of heart failure. Uncontrolled hypertension increases to frequency of heart failure hospitalizations by increase sympathetic tone. Catheter-based renal denervation has been shown to reduce blood pressure in the treatment of multidrug-resistant hypertension. We report the improvement in clinical status after renal denervation in a 47-year-old male patient with a history of hypertension, chronic ischemic heart failure, and recurrent hospitalizations for acute hypertensive pulmonary edema despite optimal medical therapy.

Fistula espontánea de LCR como manifestación de la hipertensión intracraneal idiopática / Spontaneous CSF fistula as manifestation of idiopathic intracranial hypertension

Introducción: La fistula espontanea de líquido cefalorraquídeo (LCR) de origen desconocido, es una afección poco frecuente cuya etiología se relaciona cada vez más con la hipertensión intracraneal idiopática (HII). Este estudio trata de concienciar que no deben considerase como 2 procesos distintos, sino que las fistulas pueden ser una forma de inicio, requiriendo un estudio y tratamiento posterior. Se describen las técnicas de reparación, así como el estudio de la HII. Resultados: Se trataron 8 pacientes, 5 mujeres y 3 varones, con edades comprendidas entre 46 y 72 años, con diagnóstico de fistula espontánea de LCR, 4 nasales y 4 óticas a los que se le sometió a tratamiento quirúrgico. Tras la reparación se realizó un estudio diagnóstico para la HII mediante RMN y angio-RM, presentando en todos los casos una estenosis de seno venoso transverso. Los valores de presión intracraneal obtenidos mediante punción lumbar mostraron valores de 20mmHg o superiores. Todos los pacientes fueron diagnosticados de HII. El seguimiento a un año no reveló ninguna recidiva de las fistulas, manteniendo un control de la HII. Conclusión: A pesar de su escasa frecuencia tanto de las fistulas craneales de LCR como de la HII, debe considerarse una asociación de ambas afecciones continuando el estudio y vigilancia de estos pacientes tras el cierre de la fístula.(AU)

Introduction: Spontaneous cerebrospinal fluid (CSF) fistula, of unknown origin, is a rare condition whose etiology is increasingly related to idiopathic intracranial hypertension (IIH). This study tries to raise awareness that they should not be considered as two different processes, but that fistulas can be a form of debut, requiring a study and subsequent treatment. Repair techniques are described, as well as the study of IIH. Results: We treated eight patients, five women and three men, aged between 46 and 72 years, with a diagnosis of spontaneous CSF fistula, four nasal and four otics who underwent surgical treatment. After repair, a diagnostic study was performed for IIH by MRI and angio-MRI, presenting in all cases a transverse venous sinus stenosis. The intracranial pressure values obtained by lumbar puncture showed values of 20mmHg or higher. All patients were diagnosed with IIH. The one-year follow-up did not reveal any recurrence of the fistulas, maintaining a control of the IIH. Conclusion: Despite their low frequency of both cranial CSF fistula and IIH, an association of both conditions should be considered by continuing the study and surveillance of these patients after fistula closure.(AU)

Baja disponibilidad de recursos y apoyo para atender a personas con diabetes e hipertensión arterial en las Unidades de Salud de la Familia de Paraguay

Introducción: Paraguay asumió el reto de lograr cobertura universal mediante redes basadas en Atención Primaria de la Salud con Unidades de Salud de la Familia (USF) en el primer nivel de atención. Un desafío es la atención integral ante enfermedades no transmisibles, principal causa de mortalidad en el país. Objetivo: analizar la capacidad de las USF para la atención de personas con hipertensión arterial y diabetes en el sistema nacional de salud. El diseño fue no experimental, cuantitativo, transversal, descriptivo con componente analítico. Metodología: Incluyó a 761 USF de 12 regiones sanitarias agrupados en 4 ejes territoriales. Se adaptó el método de evaluación SARA de la OMS con 75 variables, aplicando un cuestionario a profesionales de salud entre noviembre y diciembre de 2022. Se calculó índices de disponibilidad y preparación así como un índice que los integra. La medida continua de estos índices se categorizó en 3 grupos: suficiente >0,75 a 1; intermedio 0,5 a 0,75 y bajo <0,5. Resultados: Solo en el 38 % de las USF el índice de disponibilidad fue suficiente, en el 31,5 % para el índice de preparación y en el 31,1 % para el índice integrador SARA DM/HTA. El desempeño se asoció de forma significativa con el eje territorial no así con el área ni con la cobertura a población indígena Discusión: las USF presentaron limitaciones para la atención de personas con diabetes e hipertensión en estas regiones del país.

Introduction: Paraguay assumed the challenge of achieving universal coverage through networks based on Primary Health Care with Family Health Units (USF) at the first level of care. One challenge is comprehensive care for non-communicable diseases, the main cause of mortality in the country. Objective: to analyze the capacity of the USF to care for people with high blood pressure and diabetes in the national health system. The design was non-experimental, quantitative, cross-sectional, descriptive with an analytical component. Methods: It included 761 USF from 12 health regions grouped into 4 territorial axes. The WHO SARA evaluation method was adapted with 75 variables, applying a questionnaire to health professionals between November and December 2022. Availability and preparation indices were calculated as well as an index that integrates them. The continuous measurement of these indices was categorized into 3 groups: sufficient >0.75 to 1; intermediate 0.5 to 0.75 and low <0.5. Results: Only in 38.0% of the USF the availability index was sufficient, in 31.5% for the readiness index and in 31.1% for the SARA DM/HTA integrating index. The performance was significantly associated with the territorial axis, but not with the area or with the coverage of the indigenous population. Discussion: the USF presented limitations for the care of people with diabetes and hypertension in these regions of the country.

Feocromocitoma y paraganglioma en un hospital pediátrico de Argentina. Serie de casos / Pheochromocytoma and paraganglioma at a children's hospital in Argentina. A case series

El feocromocitoma y el paraganglioma son tumores neuroendocrinos secretores de catecolaminas. Los feocromocitomas se originan en la médula suprarrenal, mientras que los paragangliomas son extraadrenales. Se describe una serie de casos de niños con diagnóstico anatomopatológico de feocromocitoma o paraganglioma que consultaron en un hospital pediátrico de alta complejidad de Argentina. Se incluyeron 21 pacientes, 14 varones, con una mediana de edad de 11,4 años; 8 casos con feocromocitoma y 13 casos con paraganglioma. Se presentaron con hipertensión arterial 14/21. La mayoría de los paragangliomas tuvieron localización paraaórtica (9/13). Debido a que representan una causa potencialmente curable de hipertensión arterial, la sospecha clínica es muy importante. El diagnóstico temprano y la instauración de un tratamiento antihipertensivo adecuado, que permita afrontar la cirugía con normotensión arterial, aseguran la curación en la mayoría de los casos si la resección tumoral es completa.

Pheochromocytomas and paragangliomas are neuroendocrine tumors producing catecholamines. Pheochromocytomas occur in the adrenal medulla, while paragangliomas are those that occur outside the adrenal gland. Here we describe a case series of children with a pathological diagnosis of pheochromocytoma or paraganglioma who consulted at a tertiary care children's hospital in Argentina. A total of 21 patients (14 males) were included; their median age was 11.4 years; 8 children had pheochromocytoma and 13, paraganglioma. Arterial hypertension was observed in 14/21. Most paragangliomas were para-aortic (9/13). Since they are a potentially curable cause of hypertension, clinical suspicion is very important. An early diagnosis and the initiation of an adequate antihypertensive treatment, which allows the patient to undergo surgery with normal blood pressure, ensure a cure in most cases if tumor resection is complete.

Ação de prevenção e combate à hipertensão arterial: um relato de experiência em uma liga acadêmica de medicina / Acción para prevenir y combatir la hipertensión arterial: un reporte de experiencia en una liga académica de medicina / Initiative to prevent and control arterial hypertension: a report of an experience in an academic medicine league

Introdução: A hipertensão arterial sistêmica é uma das doenças crônicas de maior prevalência no Brasil, sendo esta, juntamente com outras doenças crônicas, o foco de atenção das unidades primárias de saúde. Desta forma, atividades de educação em saúde relacionadas à prevenção e combate a hipertensão arterial sistêmica são de grande importância para reduzir a incidência dessa doença na população. Objetivo: Nesse sentido, o presente relato possui uma abordagem qualitativa descritiva exploratória, de uma experiência dos membros de uma liga acadêmica de medicina de uma universidade no Sul de Santa Catarina. Metodologia: A abordagem do público se deu através de um projeto social no ambulatório de especialidades médicas da universidade, realizado no dia nacional de combate à hipertensão arterial de 2023, com duração de 11 horas. Neste projeto, contou com 12 membros da liga e 79 pacientes com idade média de 42 anos, foram distribuídos panfletos com informações importantes sobre hipertensão, além de outras ações, como: esclarecimento de dúvidas, distribuição demudas frutíferas e frutas, aferições de pressão arterial, encaminhamentos para consultas com clínico geral e nutricionista. Resultados: A maioria das Pressões Arteriais aferidas estava dentro da normalidade; no entanto, foram identificados alguns casos de pré-hipertensão e hipertensão ainda não diagnosticadas, além de casos em que a pressão arterial estava descompensada mesmo com tratamento farmacológico(50% dos pacientes hipertensos), incluindo um caso de crise hipertensiva, também foi possível perceber o desconhecimento do público sobre a PA e seus riscos a saúde. Conclusões: Conclui-se que é necessária a conscientização e educação em saúde das pessoas a respeito do que é a hipertensão arterial sistêmica, uma vez que, cerca de, 49%dos pacientes estavam com Índice de Massa Corporal acima de25e 37% com pressão arterial acima de 120x80mmHg (AU).

Introduction: Systemic arterial hypertension is one of the most prevalent chronic diseases in Brazil. Together with other chronic diseases, this condition is the focus of attention in the primary health units. Therefore, health education with view at preventing and controlling systemic arterial hypertension is of great importance to reduce the incidence of this disease in the population.Objective:, the present report is an exploratory descriptive qualitative approach of an Academic Medical League's members' experience at a university in the south of Santa Catarina.Methodology: The target audience was approached through a social project held at the university's medical specialty outpatient clinic on the national day of high blood pressure control in 2023 with an 11 hours duration. This project involved 12 members of the League and 79 patients. Patients' average age was 42 years. Leaflets containing important information about hypertension were distributed. Further initiatives included answering questions, fruit seedlings and fruits distribution, assessment of blood pressure, referring people to a general practitioner and to a nutritionist. Results: Blood pressure of most of the individuals who had their blood pressure measured at the event was within normal range; however, some cases of undiagnosed pre-hypertension and hypertension were identified, in addition to cases in which blood pressure was decompensated despite pharmacological treatment (50% of hypertensive patients); this included one case of hypertensive crisis. It was also evident the audience's lack of knowledge about blood pressure and its health risks.Conclusions: it is necessary to raise awareness and improve health education among people regarding what systemic arterial hypertension is, since approximately 49% of patients had a body mass index above 25 and 37% had a blood pressure above 120x80 mmHg (AU).

Introducción: La hipertensión arterial sistémica es una de las enfermedades crónicas más prevalentes en Brasil. Junto con otras enfermedades crónicas, es foco de atención en las unidades primarias de salud. Por lo tanto, las actividades de educación sanitaria relacionadas con la prevención y el combate de la hipertensión arterial sistémica son de gran importancia para reducir la incidencia de esta enfermedad en la población.Objetivo: El presente relato tiene un enfoque cualitativo descriptivo exploratorio basado en una experiencia de miembros de una liga médica académica de la universidad del sur de Santa Catarina.Metodología: Se acercó al público a través de un proyecto social realizado en el ambulatorio de especialidades médicas de la universidad, en el día nacional de combate a la hipertensión arterial del año 2023, que tuve una duración de 11 horas. En este proyecto participaron 12 integrantes de la liga y 79 pacientes con promedio de 42 años; se distribuyeron folletos con información importante sobre la hipertensión, además de otras iniciativas como: aclarar dudas, repartir plantones y frutas, medir la presión arterial, derivaciones para consultas con médico general y nutricionista. Resultados: La mayoría de las presiones medidas estuvieron dentro de los límites normales; sin embargo, se identificaron algunos casos de prehipertensión e hipertensión no diagnosticadas, además de casos en los que la presión arterial se descompensaba incluso con tratamiento farmacológico (50% de los hipertensos); hubo un caso de crisis hipertensiva. También se pudo notar la falta de conocimiento delpúblico sobre la PA y sus riesgos para la salud. Conclusiones: Se concluye que es necesario generar conciencia y educación en salud en las personas respecto de la hipertensión arterial sistémica, ya que aproximadamente el 49% de los pacientes tenían un Índice de Masa Corporal superior a 25 y el 37% tenían una presión superior a 120x80 mmHg (AU).

Prognostic value of anti-IFI16 autoantibodies in pulmonary arterial hypertension and mortality in patients with systemic sclerosis / Valor pronóstico de los autoanticuerpos anti-IFI16 en la hipertensión arterial pulmonar y en la mortalidad en los pacientes con esclerodermia sistémica

Objectives: To determine the diagnostic value of anti-interferon gamma inducible protein 16 (IFI16) autoantibodies in systemic sclerosis (SSc) patients negative for all tested SSc-specific autoantibodies (SSc-seronegative patients) and to evaluate the clinical significance of these autoantibodies, whether isolated or in the presence of anti-centromere autoantibodies (ACA). Methods: Overall, 58 SSc-seronegative and 66 ACA-positive patients were included in the study. All patients were tested for anti-IFI16 autoantibodies by an in-house direct ELISA. Associations between clinical parameters and anti-IFI16 autoantibodies were analysed. Results: Overall, 17.2% of SSc-seronegative and 39.4% of ACA-positive patients were positive for anti-IFI16 autoantibodies. Anti-IFI16 autoantibodies were found only in patients within the limited cutaneous SSc (lcSSc) subset. A positive association between anti-IFI16 positivity and isolated pulmonary arterial hypertension (PAH) was found (odds ratio [OR]=5.07; p=0.014) even after adjusting for ACA status (OR=4.99; p=0.019). Anti-IFI16-positive patients were found to have poorer overall survival than negative patients (p=0.032). Cumulative survival rates at 10, 20 and 30 years were 96.9%, 92.5% and 68.7% for anti-IFI16-positive patients vs. 98.8%, 97.0% and 90.3% for anti-IFI16-negative-patients, respectively. Anti-IFI16-positive patients also had worse overall survival than anti-IFI16-negative patients after adjusting for ACA status in the multivariate Cox analysis (hazard ratio [HR]=3.21; p=0.043). Conclusion: Anti-IFI16 autoantibodies were associated with isolated PAH and poorer overall survival. Anti-IFI16 autoantibodies could be used as a supplementary marker of lcSSc in SSc-seronegative patients and for identifying ACA-positive patients with worse clinical outcome. (AU)

Objetivos: Determinar el valor diagnóstico de los autoanticuerpos anti-interferon gamma inducible protein 16 (IFI16) en los pacientes con esclerodermia sistémica (SSc) negativos para todos los autoanticuerpos específicos de SSc (pacientes SSc seronegativos) y evaluar el significado clínico de estos autoanticuerpos, aislados o en combinación con autoanticuerpos anticentrómero (ACA). Métodos: Se incluyeron 58 pacientes SSc seronegativos y 66 pacientes ACA positivos. Todos los pacientes se testaron para los autoanticuerpos anti-IFI16 mediante un ELISA directo «in-house». Las asociaciones entre parámetros clínicos y los autoanticuerpos anti-IFI16 fueron analizadas. Resultados: En total, el 17,2% de los pacientes SSc seronegativos y el 39,4% de los pacientes ACA positivos fueron positivos para anti-IFI16. Los autoanticuerpos anti-IFI16 se detectaron solamente en los pacientes con la forma limitada cutánea de SSc (lcSSc). Se encontró una asociación entre la positividad de anti-IFI16 y la hipertensión arterial pulmonar (HAP) aislada (odds ratio [OR]: 5,07; p=0,014), incluso cuando se ajustó el análisis a la presencia o ausencia de ACA (OR: 4,99; p=0,019). Los pacientes anti-IFI16 positivos mostraron una peor supervivencia general que los pacientes negativos (p=0,032). Las ratios de supervivencia acumulada a 10, 20 y 30 años fueron respectivamente del 96,9, 92,5 y 68,7% para los pacientes anti-IFI16 positivos frente al 98,8, 97,0 y 90,3% para los anti-IFI16 negativos. Los pacientes anti-IFI16 positivos también tenían una supervivencia general menor que los pacientes anti-IFI16 negativos tras ajustar para la presencia o ausencia de ACA mediante análisis multivariado de Cox (hazard ratio [HR]: 3,21; p=0,043)...

FACTORS ASSOCIATED WITH ERC-5 IN PATIENTS OF AN EPS IN VALLE DEL CAUCA 2018-2020 / FACTORES ASOCIADOS A LA ERC-5 EN PACIENTES DE UNA EPS DEL VALLE DEL CAUCA 2018-2020

Introduction: Chronic Kidney Disease (CKD) involves a progressive deterioration in kidney function, affecting the ability to filter metabolic waste. Factors such as age, family history, ethnicity, sex, and unhealthy habits may contribute to progression to stage 5 (CKD-5). Methodology: Retrospective observational study analyzed patients with hypertension, diabetes, morbid obesity, dyslipidemia and CKD in Valle del Cauca from 2018 to 2020. Cases with CKD-5, previous dialysis, and significant changes were excluded. A census was used as a sampling method, consolidating quarterly data in 12 databases. The analysis addressed sociodemographic and clinical factors, evaluating associations with binary logistic regression, and the study was ethically approved. Results: In a cohort of 57,643 patients with CKD stages 1 to 4, the majority began follow-up in stages 2 and 3. The prevalent comorbidities were hypertension, overweight and obesity. The incidence of CKD-5 was 6 new cases per 1000 patients, being higher in the population aged 30 to 44 years, male, non-ethnic, not belonging to vulnerable groups and residing in certain municipalities. Factors such as uncontrolled blood pressure, lack of specific medication and follow-up in advanced renal stages were significantly associated with the incidence of CKD stage 5. In addition, a direct relationship was observed between the advancement of renal stage and the increase in creatinine in the blood, albumin in urine, total cholesterol and HDL cholesterol. Patients who advanced to stage 5 showed significantly higher levels of blood creatinine, albuminuria, total cholesterol, and LDL cholesterol compared to those who remained in stage 4 or lower.

Introducción: La Enfermedad Renal Crónica (ERC) implica un deterioro progresivo en la función renal, afectando la capacidad de filtrar desechos metabólicos. Factores como edad, antecedentes familiares, etnia, sexo, y hábitos poco saludables pueden contribuir a la progresión hacia el estadio 5 (ERC-5). Metodología: Estudio observacional retrospectivo analizó pacientes con hipertensión, diabetes, obesidad mórbida, dislipidemia y ERC en el Valle del Cauca de 2018 a 2020. Se excluyeron casos con ERC-5, diálisis previa, y cambios significativos. Se utilizó un censo como método de muestreo, consolidando datos trimestrales en 12 bases. El análisis abordó factores sociodemográficos y clínicos, evaluando asociaciones con regresión logística binaria, y el estudio fue éticamente aprobado. Resultados: En una cohorte de 57,643 pacientes con ERC estadios 1 a 4, la mayoría inició el seguimiento en estadios 2 y 3. Las comorbilidades prevalentes fueron hipertensión, sobrepeso y obesidad. La incidencia de ERC-5 fue de 6 casos nuevos por cada 1000 pacientes, siendo mayor en población de 30 a 44 años, sexo masculino, no étnica, no perteneciente a grupos vulnerables y residente en ciertos municipios. Factores como la presión arterial no controlada, falta de medicación específica y seguimiento en estadios renales avanzados se asociaron significativamente con la incidencia de ERC estadio 5. Además, se observó una relación directa entre el avance de estadio renal y el incremento de creatinina en sangre, albumina en orina, colesterol total y colesterol HDL. Los pacientes que avanzaron a estadio 5 mostraron niveles significativamente superiores de creatinina en sangre, albuminuria, colesterol total y colesterol LDL en comparación con los que permanecieron en fase 4 o inferior.

Prevalence, impact and management of hypertension-mediated organ damage in type 2 diabetes patients.

OBJECTIVE: To determine the prevalence, impact and management of hypertension-mediated organ damage (HMOD) according to the presence of type 2 diabetes (T2DM). METHODS: IBERICAN is an ongoing multicenter, observational and prospective study, including outpatients aged 18-85 years who attended the Primary Care setting in Spain. In this study, the prevalence, impact and management of HMOD according to the presence of T2DM at baseline were analyzed. RESULTS: At baseline, 8066 patients (20.2% T2DM, 28.6% HMOD) were analyzed. Among patients with T2DM, 31.7% had hypertension, 29.8% dyslipidemia and 29.4% obesity and 49.3% had ≥1 HMOD, mainly high pulse pressure (29.6%), albuminuria (16.2%) and moderate renal impairment (13.6%). The presence of T2DM significantly increased the risk of having CV risk factors and HMOD. Among T2DM population, patients with HMOD had more dyslipidemia (78.2% vs 70.5%; P=0.001), hypertension (75.4% vs 66.4%; P=0.001), any CV disease (39.6% vs 16.1%; P=0.001) and received more drugs. Despite the majority of types of glucose-lowering agents were more frequently taken by those patients with HMOD, compared to the total T2DM population, the use of SGLT2 inhibitors and GLP-1 receptor agonists was marginal. CONCLUSIONS: In patients daily attended in primary care setting in Spain, one in five patients had T2DM and nearly half of these patients had HMOD. In patients with T2DM, the presence of HMOD was associated with a higher risk of CV risk factors and CV disease. Despite the very high CV risk, the use of glucose-lowering agents with proven CV benefit was markedly low.

Renin-angiotensin-aldosterone system blockers effect in chronic kidney disease progression in hypertensive elderly patients without proteinuria: PROERCAN trial.

INTRODUCTION: Evidence about nefroprotective effect with RAAS blockers in elderly patients with chronic kidney disease (CKD) without proteinuria is lacking. The primary outcome of our study is to evaluate the impact of RAAS blockers in CKD progression in elderly patients without proteinuria. MATERIALS AND METHODS: Multicenter open-label, randomized controlled clinical trial including patients over 65 year-old with hypertension and CKD stages 3-4 without proteinuria. Patients were randomized in a 1:1 ratio to either receive RAAS blockers or other antihypertensive drugs and were followed up for three years. Primary outcome is estimated glomerular filtration rate (eGFR) decline at 3 years. Secondary outcome measures include BP control, renal and cardiovascular events and mortality. RESULTS: 88 patients were included with a mean age of 77.9±6.1 years and a follow up period of 3 years: 40 were randomized to RAAS group and 48 to standard treatment. Ethiology of CKD was: 53 vascular, 16 interstitial and 19 of unknown ethiology. In the RAAS group eGFR slope during follow up was -4.3±1.1ml/min, whereas in the standard treatment group an increase on eGFR was observed after 3 years (+4.6±0.4ml/min), p=0.024. We found no differences in blood pressure control, number of antihypertensive drugs, albuminuria, potassium serum levels, incidence of cardiovascular events nor mortality during the follow up period. CONCLUSIONS: In elderly patients without diabetes nor cardiopathy and with non proteinuric CKD the use of RAAS blockers does not show a reduction in CKD progression.
