ABSTRACT

ObjetivoEvaluar si existen diferencias en los resultados del ensayo clínico CLOROTIC según el sexo. Métodos Subanálisis del ensayo CLOROTIC, que evaluó la eficacia y la seguridad de añadir hidroclorotiazida (HCTZ) o placebo a furosemida intravenosa en pacientes con insuficiencia cardiaca aguda (ICA). Los resultados primarios y secundarios incluyeron cambios en el peso y la disnea a las 72 y 96horas, medidas de la respuesta diurética y la mortalidad y reingresos a los 30 y 90días. Se evaluó la influencia del sexo en los resultados primarios y secundarios y de seguridad. Resultados De los 230 pacientes incluidos, 111 (48%) eran mujeres, que tenían más edad y valores más elevados de fracción de eyección ventricular izquierda. Los hombres tenían más cardiopatía isquémica, enfermedad pulmonar obstructiva crónica y mayor valor de péptidos natriuréticos. La adición de HCTZ a furosemida se asoció con una mayor pérdida de peso a las 72/96horas y mejor respuesta diurética a las 24horas en comparación con el placebo, sin diferencias significativas según el sexo (ningún valor de p para la interacción fue significativo). El deterioro de la función renal fue más frecuente en mujeres (OR: 8,68; IC95%: 3,41-24,63) que en varones (OR: 2,5; IC95%: 0,99-4,87), p=0,027. No hubo diferencias en la mortalidad ni en los reingresos a los 30/90días. Conclusión La adición de HCTZ a furosemida intravenosa es una estrategia eficaz para mejorar la respuesta diurética en la ICA sin diferencias según el sexo. Sin embargo, el deterioro de la función renal es más frecuente en las mujeres. (AU)


Aims The addition of hydrochlorothiazide (HCTZ) to furosemide improved the diuretic response in patients with acute heart failure (AHF) in the CLOROTIC trial. Our aim was to evaluate if there were differences in clinical characteristics and outcomes according to sex. Methods This is a post hoc analysis of the CLOROTIC trial, including 230 patients with AHF randomized to receive HCTZ or placebo in addition to an intravenous furosemide regimen. The primary and secondary outcomes included changes in weight and patient-reported dyspnoea 72 and 96h after randomization, metrics of diuretic response and mortality/rehospitalizations at 30 and 90days. The influence of sex on primary, secondary and safety outcomes was evaluated. Results One hundred and eleven (48%) women were included in the study. Women were older and had higher values of left ventricular ejection fraction. Men had more ischemic cardiomyopathy and chronic obstructive pulmonary disease and higher values of natriuretic peptides. The addition of HCTZ to furosemide was associated to a greatest weight loss at 72/96h, better metrics of diuretic response and higher 24-h diuresis compared to placebo without significant differences according to sex (all P-values for interaction were not significant). Worsening renal function occurred more frequently in women (OR: 8.68; 95%CI: 3.41-24.63) than men (OR: 2.5; 95%CI: 0.99-4.87), P=.027. There were no differences in mortality or rehospitalizations at 30/90days. Conclusion Adding HCTZ to intravenous furosemide is an effective strategy to improve diuretic response in AHF with no difference according to sex, but worsening renal function was more frequent in women.

ABSTRACT

AIMS: The addition of hydrochlorothiazide (HCTZ) to furosemide improved the diuretic response in patients with acute heart failure (AHF) in the CLOROTIC trial. Our aim was to evaluate if there were differences in clinical characteristics and outcomes according to sex. METHODS: This is a post-hoc analysis of the CLOROTIC trial, including 230 patients with AHF randomized to receive HCTZ or placebo in addition to an intravenous furosemide regimen. The primary and secondary outcomes included changes in weight and patient-reported dyspnoea 72 and 96 h after randomization, metrics of diuretic response and mortality/rehospitalizations at 30 and 90 days. The influence of sex on primary, secondary and safety outcomes was evaluated. RESULTS: One hundred and eleven (48%) women were included in the study. Women were older and had higher values of left ventricular ejection fraction. Men had more ischemic cardiomyopathy and chronic obstructive pulmonary disease and higher values of natriuretic peptides. The addition of HCTZ to furosemide was associated to a greatest weight loss at 72/96 h, better metrics of diuretic response and higher 24-h diuresis compared to placebo without significant differences according to sex (all p-values for interaction were not significant). Worsening renal function occurred more frequently in women (OR [95%CI]: 8.68 [3.41-24.63]) than men (OR [95%CI]: 2.5 [0.99-4.87]), p = 0.027. There were no differences in mortality or rehospitalizations at 30/90 days. CONCLUSION: Adding HCTZ to intravenous furosemide is an effective strategy to improve diuretic response in AHF with no difference according to sex, but worsening renal function was more frequent in women.

ABSTRACT

Hydrochlorothiazide and other thiazide diuretics have been used for decades to treat high blood pressure, heart failure, and chronic kidney disease. Thiazides have been linked to photosensitivity with heterogeneous clinical manifestations and recovery times. Diagnosis can be aided by phototesting, photopatch testing, and skin biopsy. Long-term use of hydrochlorothiazide has been linked to an increased dose-dependent risk of certain types of skin cancer in recent years. In this review, we also look at other less common or lesser-known adverse effects of thiazide diuretics that have been described in isolated reports.

ABSTRACT

La hidroclorotiazida (HCTZ) y otros diuréticos tiazídicos son fármacos que se han empleado desde hace décadas para el tratamiento de la hipertensión arterial, la insuficiencia cardíaca o la enfermedad renal crónica. Las tiazidas se han asociado con reacciones de fotosensibilidad, siendo heterogéneas en cuanto a manifestación clínica y tiempo de recuperación, y en las cuales, el fototest, el fotoparche y la biopsia cutánea nos pueden ser útiles en el diagnóstico. En relación con estos fármacos, en los últimos años se ha evidenciado también un mayor riesgo dosis-dependiente de desarrollar determinados tipos de cáncer cutáneo en pacientes tratados de forma crónica con HCTZ. En esta revisión se comentan, asimismo, otros efectos adversos menos habituales o reconocidos de los diuréticos tiazídicos reportados de forma aislada en la literatura (AU)

ABSTRACT

INTRODUCTION: Both dietary restriction of sodium chloride (NaCl) and treatment with thiazides have been used in hypercalciuric patients. OBJECTIVES: To calculate regular salt intake and investigate the correlation between natriuresis and urinary calcium with usual diet (B) and after changing the amount of NaCl intake and administration of thiazides. MATERIAL AND METHODS: Nineteen healthy young individuals had their diet replaced by 2l of Nutrison® Low Sodium (500mg sodium/day) daily for two days. Then, 5g of NaCl were added every two days («5¼, «10¼ and «15¼), administering 50mg (H50) and 100mg (H100) of Higroton® on the last two days. Blood sodium, plasma renin activity (PRA) and aldosterone were determined in venous blood samples, as were urinary sodium and calcium. STATISTICAL ANALYSIS: Wilcoxon t-test and the Pearson linear correlation were calculated. RESULTS: Urinary Na (mEq/24h): 210.3±87.6 («B¼); 42.7±20.4 («5¼); 135.5±50.6 («10¼); 225.5±56.7 («15¼). Urinary calcium (mg/24h): 207.8±93.6 («B¼); 172.8±63.1 («5¼); 206.2±87.7 («10¼); 227.4±84.1 («15¼). A positive correlation was observed between natriuresis and urinary calcium in «10¼ (r=0.47) and «15¼ (r=0.67). After Higroton®, natriuresis: 232.3±50.7; 377±4 (H50); 341.1±68.4 (H100); Ca in urine: 209.8±57.4; 213.2±67.6 (H50); 159.1±52.2 (H100). CONCLUSIONS: Salt intake in the population studied was estimated to be 14.9±4.9g/day with a positive correlation found between sodium and calcium urine output with daily intakes of 11.25 and 16.25g of salt. With the usual intake, for each gram of salt, urinary calcium increased by 5.46 mg/24 h and with 100mg of Higroton® it decreased by 50.7mg/24h. These data could be useful for the management of patients with excretory hypercalciuria or hypoparathyroidism.

ABSTRACT

Thiazides are widely used diuretics that first became available in the 1950s. The first reports of photosensitivity reactions to thiazides were published shortly after the introduction of these drugs, but few cases have been described since. We review all the cases of photosensitivity due to thiazides published up to December 2011. We found 62 cases, 33 in women and 29 in men. The most common presentation was eczematous lesions in a photodistributed pattern, and the most common causative agent was hydrochlorothiazide. The results of photobiological studies were published in only some of the cases reviewed. In most cases, phototesting revealed an abnormal response to UV-A alone or to both UV-A and UV-B. In some cases, the results of phototesting were normal and only photopatch testing yielded abnormal results. Diagnosis of photosensitivity due to thiazides requires a high degree of suspicion. Ideally, diagnosis should be confirmed by a photobiological study.

ABSTRACT

Background: Decreased bone mineral density and increased prevalence of bone fractures have been found in patients with idiopathic hypercalciuria. It is not yet clear if thiazide treatment prevent these events. Methods: We retrospectively evaluated bone mass and biochemical markers of bone turnover in response to thiazide therapy in 52 consecutive female patients with idiopathic hypercalciuria and nephrolithiasis. Patients were divided in two subgroups according to their menopausal status: 25 were pre-menopausal (Group I) and 27 were postmenopausal (Group II). Results: Osteoporosis was found in 12 patients at baseline, 9 at the lumbar spine and 6 at the femoral neck. Two were pre-menopausal and 10 were postmenopausal. Patients with osteoporosis were analyzed separately (Group III). There was a significant and persistent reduction in urinary calcium with preservation of bone mass in all the groups after a median follow-up of 51 months. Few adverse effects were found using low doses of hydrochlorothiazide / amiloride. Only in the group III we found a statistcally significant an increase in BMD at the lumbar spine of 9.5% and an increase in BMD at femoral neck of 4.4% that did not reach statistical significance. Conclusions: We conclude that correction of hypercalciuria during long term treatment with low-dose hydrochlorothiazide//amiloride in women with nephrolithiasis prevents bone loss and in those with osteoporosis can lead to a significant increase in bone mineral density at the lumbar spine. Few adverse effects were seen during treatment and no interruption of therapy was necessary.(AU)


Introducción: Reducción de la densidad mineral ósea y aumento de la prevalencia de fracturas óseas se han encontrado en pacientes con hipercalciuria idiopática. Aún no está claro si el tratamiento con tiazidas prevenir estos eventos. Métodos: Evaluamos retrospectivamente la masa ósea y los marcadores bioquímicos de recambio óseo en respuesta a la terapia con tiazidas en 52 pacientes femeninos consecutivos con hipercalciuria idiopática y nefrolitiasis. Los pacientes fueron divididos en dos subgrupos de acuerdo a su estado de la menopausia : 25 fueron pre-menopáusicas (Grupo I) y 27 eran posmenopáusicas (Grupo II). Resultados: La osteoporosis se encontró en 12 pacientes al inicio del estudio, 9 en la columna lumbar y 6 en el cuello femoral. Dos eran premenopáusicas y 10 eran posmenopáusicas. Los pacientes con osteoporosis se analizaron por separado (Grupo III). Hubo una reducción significativa y persistente en el calcio urinario con la preservación de la masa ósea en todos los grupos después de una mediana de seguimiento de 51 meses. Pocos efectos adversos se encuentran utilizando dosis bajasde hidroclorotiazida / amilorida. Sólo en el grupo III encontramos un aumento estadísticamente significativo en la DMO de la columna lumbar del 9,5% y un aumento de la densidad mineral ósea en el cuello femoral de 4,4% que no alcanzó significación estadística. Conclusión: Llegamos a la conclusión de que la corrección de la hipercalciuria durante el tratamiento a largo plazo con dosis bajas de hidroclorotiazida / / amilorida en mujeres con nefrolitiasis previene la pérdida ósea y en aquellos con osteoporosis puede conducir a un aumento significativo en la densidad mineral ósea en la columna lumbar. Pocos se observaron efectos adversos durante el tratamiento y no hay interrupción de la terapia era necesario.(AU)

ABSTRACT

Objective Evaluating differences in the suitable prescription of thiazides in hypertense patients, according to affiliation regime. Materials and methods This was an analytical cross-sectional study. The database from a previous study was used regarding two groups of hypertense patients (subsidised regime and contributory regime) who had attended out-patient consultation between 01-09-2007 and 29-02-2008. Ideal therapy was evaluated in both groups. Univariate and multivariate analysis was carried out. Results 136 patients (contributory: 41.9 percent; subsidised: 58.1 percent). Subsidised regime patients were older (mean=68.8±10) than those from the contributory regime (mean=64.1±11.1) (t-test, p=0.0110). Prescribing antihypertensive drugs was ideal in 49/136 of the patients (36.0 percent). Ideal prescription accounted for 24/79 (30 percent) of the patients in the subsidised regime and 25/57 (43.8 percent) in the contributory one (OR=1.79; 95 percent CI:0.88-3.64). Older people (aged ≥ 65yo) were at risk of receiving a non-ideal prescription (OR=2.12; 95 percentCI:1.02-4.38) whilst this was not so in the subsidised regime (OR=1.62; 95 percent CI:0.78-3.35). Conclusions Ideal prescription of antihypertensive drugs was low in the population being studied. There were differences regarding age ideal prescription but not concerning affiliation regime. It is suggested that a longitudinal study be carried out in the future.


Objetivo Evaluar las diferencias en la adecuada prescripción de tiazidas en pacientes hipertensos, según régimen de afiliación. Materiales y métodos Estudio de corte transversal analítico. Se utilizó la base de datos de un estudio previo, dos grupos de pacientes hipertensos: régimen subsidiado y régimen contributivo que asistieron a consulta externa entre el 01-09-2007 y el 29-02-2008. Se evaluó terapia ideal en los dos grupos. Se realizó análisis univariado y multivariado. Resultados Se estudiaron 136 pacientes (contributivo: 41,9 por ciento; subsidiado: 58,1 por ciento). Los pacientes del régimen subsidiado fueron mayores (promedio= 68,8±10) que los del contributivo (promedio=64,1±11.1) (t-test, p=0,0110). La prescripción de antihipertensivos fue ideal en 49/136 (36,0 por ciento). En el régimen subsidiado la prescripción fue ideal en 24/79 (30 por ciento) y en el contributivo en 25/57 (43,8 por ciento) (OR: 1,79 IC95 por ciento (0,88-3,64)). La edad ≥65años fue riesgo de prescripción no ideal (OR: 2.12, IC95 por ciento(1,02-4,38)), mientras que no lo fue estar en el régimen subsidiado (OR=1,62, IC95 por ciento(0,78-3,35). Conclusiones La prescripción ideal de antihipertensivos es baja. Hay diferencias en la edad, en la prescripción ideal, mas no por régimen de afiliación. Se sugiere un estudio longitudinal en el futuro.
