Study of Cardiac Manifestations in Patients with HIV Infection and Their Correlation with CD4 Count in Indian Population.

Background: HIV continues to be a major global public health issue. In 2014 an estimated 36.9 million people were living with HIV, a global prevalence of 0.8 %. The clinical spectrum of HIV infection encompasses a spectrum ranging from an acute syndrome associated with primary infection to a prolonged symptomatic state to an advanced cardiac disease in HIV affected patients is becoming more prevalent as therapy and longevity improve Infection HIV is one of the causes of acquired heart disease in these patients. With advances in the management of patients living with HIV and AIDS (PLHA), not only survival has increased but manifestations of late stage HIV infection are encountered more often including cardiovascular complications. Aims and Objectives: To determine the prevalence and characteristics of cardiac manifestations in patients with HIV infection and to evaluate their correlation with CD4 count. Methods: During the period of 1 year from July 2015 to September 2016, total 100 cases of HIV/AIDS were included. The occurrence of cardiac involvement in HIV/AIDS cases was determined based on cardiac enzymes, ECG findings & 2D Echocardiography findings. An attempt was made to correlate various cardiac findings with CD4 T cell count. Results: Male to female ratio was 3:1. Common clinical symptoms were fever (68%), cough (44%) & extertional breathlessness (33%) Echocardiographic abnormalities were seen in 54.3% of patients. Reduced ejection fraction (below 50%) and fractional shortening below 30% were the most common cardiac abnormality (46.3%) followed by pericardial effusion (16.66%), pulmonary artery hypertension (11.11%), dilated cardiomyopathy (9.25%), diastolic dysfunction (9.25%), regional wall motion abnormality (1.85%) and valvular regurgitation (5.55%) respectively. Significant statistical positive correlation was observed between low CD4 count and echocardiographic abnormalities (p < 0.001). Pericardial effusion was seen more in patients with CD4 count below 200 (p < 0.05). Maximum number of echocardiographic abnormalities was seen in WHO clinical stage IV. Conclusion: Echocardiographic abnormalities are more prevalent in HIV/AIDS patients and their prevalence increases as the CD4 count falls andoccur more in advanced stage of the disease. So we should aim at starting ART early in HIV infected patients so as to improve the quality of life of people living with HIV/AIDS.

Evaluación ecocardiográfica longitudinal en pacientes con leucemia linfoide aguda que recibieron antraciclinas durante la edad pediátrica / Longitudinal ecocardiographic assesment in patients with acute lymphoid leukemia that received anthracyclines during childhood

Introducción: La cardiotoxicidad tardía causada por el tratamiento del cáncer puede ser un problema frecuente en los sobrevivientes por lo que se decidió realizar un estudio ecocardiográfico longitudinal de la función cardiovascular con el objetivo de detectar las alteraciones causadas por la administración de antraciclinas en pacientes que tuvieron una leucemia linfoide aguda en la edad pediátrica. Métodos: se incluyeron todos los pacientes atendidos por esta leucemia en el Servicio de Pediatría del Instituto de Hematología e Inmunología ,desde abril de 2002 hasta febrero de 2015, que además debían tener al menos 2 evaluaciones ecocardiográficas posteriores a la conclusión del tratamiento. A todos se les realizó examen físico, se tomaron datos generales de las historias clínicas, se les calculó la dosis acumulativa de antraciclinas y el tiempo transcurrido hasta la realización de la evaluación. De los ecocardiogramas realizados se tomaron las medidas de aurícula izquierda, ventrículo derecho, fracción de eyección y fracción de acortamiento. Resultados : predominaron los signos de cardiotoxicidad tardía subclínica con una media de 9 años después de suspendido el tratamiento y estuvieron afectados ambos sexos por igual. En el primer ecocardiograma realizado, tres años después de la suspensión, la mayor frecuencia de alteraciones estuvieron en las medidas de aurícula izquierda y ventrículo derecho. Los estudios se repitieron cada tres años y en el tercer estudio fue más frecuente la afectación de las fracciones de eyección y de acortamiento. Se encontró que había relación estadísticamente significativa entre el uso de mayores dosis de antraciclinas y las alteraciones ecocardiográficas. Conclusiones: las afectaciones de la función cardiovascular fueron ligeras y aumentaron durante el seguimiento(AU)

Introduction Cancer therapy could cause frequent cardiac toxicity, so we decided to perform an echocardiographic longitudinal study of the late effects caused by anthracyclines administration in patients that were treated for acute lymphoid leukemia during childhood. Methods All the patients admitted in the Pediatric Service of Institute of Hematology and Immunology, with acute lymphoid leukemia since april 2002 until february 2015 and that have at least two echocardiographic studies after finishing therapy. A complete physical exammination was performed to all of them and the cumulative dose of anthracyclines received was calculated and also time until evaluation. From the echocardiograms were taken the measurements of left auricle, right ventricle, ejection fraction and shortening fraction. Results: the main findings were signs of late subclinical cardiotoxicity with a mean of 9 years after therapy completion and there were no sex predominance. In the first echocardiogram performed three years after stopping therapy there were more alterations in the measures of left auricle and right ventricle. The studies were repeated every three years and in the third one there were more alterations in ejection fraction and shortening fraction and there also were a statiscally significative relation between cumulative anthracyclines doses and echocardiographic findings. Conclusions: There were found subclinical cardiac dysfunction that increases as time goes by(AU)

Echocardiographic findings: Experience in 1,468 cases / Hallazgos ecocardiográficos: experiencia en 1,468 casos

Abstract: Background: Echocardiogram is an important diagnostic tool to evaluate cardiac disease and very usefull in diagnosis and management. It is important to know the spectrum of cardiac abnormalities detected by transthoracic echocardiography, the frequency of findings that may vary depending on the prevalence of the disease and type of studied population. Objective: To know the spectrum of findings identified in resting transthoracic echocardiography in 1,468 patients. Material and methods: A 3 years retrospective review of resting transthoracic echocardiograms in 1,468 patients. Results: The age range of the 1,468 patients was from 1 day to 94 years with mean (SD) age 51 ± 7.2 years; females 52.9% (n = 776) and males 47.1% (n = 692). One hundred thirty three patients (9.05%) had normal echocardiograms; 1,335 patients had an average of 1.8 findings/patient; 2,464 findings were classified in ten different categories: heart valves abnormalities was the most frequent alteration detected in 36.47% (n = 487); diastolic dysfunction 30.71% (n = 410); and cardiac chambers dilation 27.79% (n = 371). Conclusions: Clinical history and physical examination can not be substituted by an imaging test, but with the clinical data obtained, in conjunction with an echocardiographic study, gives us clues to the diagnosis and pathophysiology of heart disease essential for the properly evaluation and management.

Resumen: Antecedentes: La ecocardiografía es una herramienta indispensable para evaluar y manejar a las enfermedades cardiacas. Es importante conocer el espectro de anormalidades cardiacas detectadas por ecocardiografía transtorácica en reposo y la frecuencia de esos hallazgos, los cuales varían de acuerdo a cada enfermedad cardiaca. Objetivo: Reportar el espectro de hallazgos ecocardiográficos en 1,468 pacientes. Material y métodos: Los estudios ecocardiográficos transtorácicos en reposo realizados durante un período de 3 años. Resultados: Un total de 1,468 pacientes con edades comprendidas entre el primer día de vida y 94 años con edad promedio y desviación estándar de 51 ± 7.2 años; correspondiendo 52.9% (n = 776) al género femenino y 47.1% al masculino (n = 692). De los estudios, 9.05% (n = 133) fueron normales; 1,335 pacientes presentaron un promedio de1.8 hallazgos/paciente; se detectaron 2,464 hallazgos catalogándose en 10 capítulos. Los tres hallazgos más frecuentes fueron: valvulares 36.47% (n = 487); disfunción diastólica 30.71% (n = 410); y dilatación de cámaras cardiacas 27.79% (n = 371). Conclusiones: Una imagen no puede sustituir a la historia clínica y a la exploración física, siendo la ecocardiografía una prolongación de esta última, permitiendo valorar la estructura y fisiología cardiaca así como sus alteraciones, por lo que actualmente es esencial su realización en la valoración cardiaca.
