Dias CR, Canuto E, Alves LH, Alves RCP, Dias CB. Severa hiponatremia induzida pela associação de fluoxetina, hidroclorotiazida e captropil em paciente jovem. Rev Med (São Paulo). 2009 jul.-dez.;88(3/4):203-6. RESUMO: Descrevemos um caso de hiponatremia grave, com um dos níveis séricos de sódio mais baixos da literatura, secundário ao uso de fluoxetina, captopril e hidroclorotiazida. Paciente do sexo feminino, 45 anos, portadora de hipertensão arterial, vinha assintomática em uso de hidroclorotiazida e captopril, quando, a um mês da internação, iniciou-se fluoxetina devido sintomas de depressão. Paciente foi internada por rebaixamento de nível de consciência, com tomografia computadorizada de crânio evidenciando edema cerebral. Análise bioquímica revelou sódio sérico de 97 meq/L. Paciente evoluiu bem após interrupção das medicações e após administração de solução salina a 3%. O mecanismo pelo qual as drogas citadas desencadeiam hiponatremia é variável e não totalmente compreendido. No caso dos diuréticos tiazídicos, alteração na homeostase do sódio e água nos túbulos renais são os principais fatores relacionados a esse distúrbio eletrolítico. Com relação aos antidepressivos, o aumento da produção do hormônio antidiurético é, mais provavelmente, o fator associado à hiponatremia.. Os inibidores da ECA também são relacionados à hiponatremia, pois bradicinina e angiotensina seriam estimulantes da liberação do Hormônio Antidiurético. Sendo assim, a equipe médica deve fazer o rastreamento, através de uma avaliação clínica atenta e das pesquisas regulares, das concentrações séricas de sódio nesses pacientes, a fim de detectar precocemente distúrbios eletrolíticos potencialmente fatais.

Introduction:Individuals with pituitary adenomas may have organic consequences of their disease or therapy, and psychological changes can compromise their quality of life (QoL). This study aimed to determine the anthropometric profile and health indicators of patients with pituitary adenoma before and after pituitary surgery.Methods:Forty-four patients were included in this study. Out of these, 22 patients had nonfunctioning adenomas (50%), 17 acromegaly (38.6%), and 5 patients with Cushing's disease (11.4%). Anthropometric measurements included body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR). Health indicators included body fat percentage (BF%), basal metabolic rate (BMR), maximal oxygen uptake (VO2 max), and hand grip strength. Physical activity level (the International Physical Activity Questionnaire [IPAQ]), subjective perception of health, body image (Body Shape Questionnaire), body satisfaction (Stunkard Figure Rating Scale) were used.Results:The mean patient age was 47.2 ± 14.6 years; of which 25 were women (56.8%). Before surgery, 75.0% were overweight or obese, 84.1% had WC with risk of metabolic complications, and 90.0% had WHR with cardiovascular risk. There was a high BF% in 56.4% of cases, low BMR in 65.1%, lower VO2 max in 16.2%, and below-average grip strength in 88.6%. Hypopituitary patients had poorer cardiorespiratory fitness. The IPAQ showed reduction in physical activity, and 79.5% of patients were dissatisfied with their body image. Patients with nonfunctioning adenomas had better perception of their health while those with Cushing's disease had more distorted body image. Postoperatively, patients with acromegaly showed improvement in WHR and physical activity level, and patients with Cushing's disease showed improvement in anthropometric variables.Conclusions:These findings emphasize the need for continuous monitoring of this population for anthropometric indicators associated with metabolic and cardiovascular comorbidities as well as body satisfaction.
