Cardiovascular autonomic neuropathy in type 2 diabetic patients.

Diabetes is one of the most common chronic pathologies around the world, involving treatment with general clinicians, endocrinologists, cardiologists, ophthalmologists, nephrologists and a multidisciplinary team. Patients with type 2 Diabetes Mellitus (T2DM) can be affected by cardiac autonomic neuropathy, leading to increased mortality and morbidity. In this review, we will present current concepts, clinical features, diagnosis, prognosis, and possible treatment. New drugs recently developed to reduce glycemic level presented a pleiotropic effect of reducing sudden death, suggesting a potential use in patients at risk.

RESUMO Diabetes é uma das mais frequentes patologias crônicas em todo o mundo, cujo tratamento envolve uma equipe multidisciplinar, médicos generalistas, endocrinologistas, cardiologistas, nefrologistas e oftalmologistas. Pacientes com diabetes mellitus tipo 2 (DMT2) podem apresentar neuropatia autonômica cardíaca (NAC), levando a aumento de mortalidade e morbidade. Nesta revisão, apresentaremos atuais conceitos, características clínicas, diagnóstico, prognóstico e possíveis tratamentos. Novas drogas recentemente desenvolvidas para redução de níveis glicêmicos apresentaram efeito pleiotrópico de redução de morte súbita, sugerindo um potencial uso neste perfil de pacientes.

Three new Brazilian cases of 17α-hydroxylase deficiency: clinical, molecular, hormonal, and treatment features.

BACKGROUND: Deficiency of 17α-hydroxylase (17OHD) is a rare form of adrenal hyperplasia. Diagnosis is generally delayed, impairing appropriate treatment. CASE PRESENTATION: Here, we report the clinical, molecular, hormonal, and treatment data of three unrelated 17OHD patients, aged 14-16 years with hypergonadotrophic hypogonadism; uncontrolled hypertension; primary adrenal insufficiency; and high progesterone, low to normal potassium, and low dehydroepiandrosterone, androstenedione, and testosterone levels. Liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) at baseline and after an adrenocorticotropic hormone test showed low cortisol and cortisone and high deoxycorticosterone (DOC) and corticosterone levels; both DOC/21-deoxycortisol and costicosterone/cortisol ratios were very high. Patient 2 had 46,XX karyotype and patients 1 and 3, had 46,XY. A molecular analysis showed that two of the patients were homozygous for p.W406R mutation and the other patient was compound heterozygous for p.W406R and p.P428L. Hypertension was controlled only after the administration of both prednisone and mineralocorticoid antagonist. CONCLUSIONS: Hypertension in young women must lead to diagnostic suspicion, even in the pre-pubertal period. The basal level of progesterone is an indicator of 17OHD. Mineral and glucocorticoid ratios obtained from LC-MS/MS can reinforce the diagnosis. Hypertension can be controlled using glucocorticoid replacement therapy and mineralocorticoid antagonist.
