BACKGROUND: The aim of this paper was to characterize the blood pressure CR in patients with end stage chronic kidney disease (ESCKD) before and after treatment with bromocriptine compared to healthy volunteers. METHODS: Fifteen patients and nine healthy volunteers were included. Both groups underwent ambulatory 24 hours blood pressure (24 h ABPM). Patients received 2.5 mg every 8 hours of bromocriptine for eight weeks, at the end of the treatment 24 h ABPM was repeated; blood pressure CR was compared before and after treatment and with healthy volunteers. The CR was identified by the method of Cosinor. RESULTS: 64% of volunteers showed a 24 h CR, against 27% of patients (p < 0.05). After the treatment with bromocriptine 40% of patients showed RC 24 h. The mean arterial pressure decreased from 129 ± 1 mmHg to 106 ± 1 mmHg. A 12 h rhythm was identified in 45% of volunteers and 73% of patients before treatment (p < 0.05) against 60% at the end (p < 0.001), with no statistical difference with volunteers. CONCLUSIONS: The CR in blood pressure is altered in ESCKD and could be restored with bromocriptine. 12 hours rhythmicity was identified predominantly in patients with ESCKD; this rhythm was also present in the healthy volunteers.
INTRODUCCIÓN: el propósito de este estudio es caracterizar el ritmo circadiano (RC) de la presión arterial en pacientes con enfermedad renal crónica terminal (ERCT) en tratamiento con diálisis peritoneal continua ambulatoria (DPCA) antes y después del tratamiento con bromocriptina (BEC) comparándolos con voluntarios sanos. MÉTODOS: se incluyeron 15 pacientes del servicio de Nefrología y 9 voluntarios sanos. Se les realizó monitoreo ambulatorio de presión arterial de 24 horas (MAPA). Los pacientes recibieron 2.5 mg de BEC cada 8 hora durante ocho semanas, al final del tratamiento se repitió el MAPA; el RC de la presión arterial se comparó antes y después del tratamiento y con los voluntarios. Resultados: el 64% de los voluntarios exhibieron RC de 24 horas, frente al 27% de los pacientes (p < 0.05). Después del tratamiento con BEC, el 40% de pacientes mostraron RC de 24 h. El mesor de la presión arterial media disminuyó de 129 ± 1 mmHg a 106 ± 1 mmHg (p < 0.05). Se identificó un ritmo de 12 h en 45% de los voluntarios y en el 73% de los pacientes antes del tratamiento (p < 0.05) frente a 60% al final (p < 0.001), sin diferencia estadística con los voluntarios. CONCLUSIONES: el RC de la presión arterial esta alterado en la IRCT y se restableció con BEC. La ritmicidad de 12 h predominó en los pacientes con ERCT, también presente en los voluntarios sanos.

OBJECTIVE: To determine the incidence (preliminary) of allergic rhinitis in a population-based sample of adolescents and its relation on how they meet basic and affective need satisfaction. MATERIAL AND METHODS: We used ISAAC survey to assess rhinitis-related symptoms in a population-based sample of adolescents from Morelia, Michoacán, Mexico. Some items were added to the survey to evaluate how they meet basic and affective needs. Random sample included 1,333 adolescents aged 11-16 years from several schools of Morelia, Michoacán. Allergic rhinitis impact on basic and affective need satisfaction was assessed. Relative risk (RR) and 95% confidence interval (CI) were estimated. RESULTS AND DISCUSSION: Until 2003, such disease was diagnosed in 12% of cases; however, the number went up after the survey: rhinitis-related symptoms were seen in 46% of those polled, of which prevalence, sensitivity and specificity rates were 27, 90, 70%, respectively. More symptoms were reported from July through December. Sixty percent of adolescents with allergic rhinitis reported sleep disturbances, with adverse effects on bed rest period (RR 2.64) [1.01-6.94]. Well-balanced diet was seen in 62% of adolescents with such disease (RR 1.56) [1.34-1.79]. Sixty-seven percent of such teenagers said that the disease does no interfere with their performance in school (RR 1.41) [0.61-3.24] and 22% felt unaccepted (RR 1.8) [0.795-16.63]. CONCLUSIONS: The estimation of incidence of allergic rhinitis found in this study is higher than in other reports. Basic and affective need satisfaction was affected; thus, implementation of psychotherapy within a multi-disciplinary approach is required.
