ABSTRACT

Abstract A previously healthy 24 yo male presented with a two-month history of epigastric pain, nausea, vomiting, fatigue and malaise. He reported abuse of different substances, including an injectable veterinary vitamin compound, which contains high doses of vitamin A, D and E, and an oily vehicle that induces local edema and enhances muscle volume. Serum creatinine was 3.1 mg/dL, alanine transaminase 160 mg/dL, aspartate transaminase 11 mg/dL, total testosterone 23 ng/dL, 25-OH-vitamin D >150 ng/mL (toxicity >100), 1,25-OH-vitamin D 80 pg/mL, vitamin A 0.7 mg/dL, parathormone <3 pg/mL, total calcium 13.6 mg/dL, 24-hour urinary calcium 635 mg/24h (RV 42-353). A urinary tract ultrasound demonstrated signs of parenchymal nephropathy. The diagnosis was hypercalcemia and acute renal failure secondary to vitamin D intoxication. He was initially treated with intravenous hydration, furosemide and prednisone. On the fifth day of hospitalization a dose of pamidronate disodium was added. The patient evolved with serum calcium and renal function normalization. Thirty days later he presented normal clinical and laboratory tests, except 25-OH-vitamin D that was persistently increased (107 ng/mL), as it may take several months to normalize. This case report is a warning of the risks related to the use of veterinary substances for aesthetics purposes.


Resumo Um paciente de 24 anos do sexo masculino, previamente hígido, apresentou-se com uma história de dois meses de dor epigástrica, náuseas, vômitos, fadiga e mal-estar. Ele relatava abuso de diferentes substâncias, incluindo um composto vitamínico veterinário injetável contendo altas doses de vitamina A, D e E, e um veículo oleoso que induz edema local com aumento de volume muscular. A creatinina sérica estava 3,1 mg/dL, alanina transaminase 160 mg/dL, aspartato transaminase 11 mg/dL, testosterona total 23 ng/dL, 25-OH-vitamina D > 150 ng/mL (toxicidade > 100), 1,25-OH-vitamina D 80 pg/mL, vitamina A 0,7 mg/dL, paratormônio < 3 pg/mL, cálcio total 13,6 mg/dL, cálcio urinário de 24h 635 mg/24h (VR 42-353). Uma ultrassonografia do trato urinário demonstrou sinais de nefropatia parenquimatosa. O diagnóstico foi hipercalcemia e insuficiência renal aguda secundária a intoxicação por vitamina D. Ele foi tratado inicialmente com hidratação intravenosa, furosemida e prednisona. No quinto dia de hospitalização uma dose de pamidronato dissódico foi adicionada. O paciente evoluiu com normalização do cálcio sérico e da função renal. Trinta dias depois ele apresentou testes clínicos e laboratoriais normais, exceto a 25-OH-vitamina D que estava persistentemente elevada (107 ng/mL), já que ela pode demorar vários meses para normalizar. Este relato de caso é um alerta aos riscos relacionados ao uso de substâncias veterinárias para fins estéticos.

ABSTRACT

Objective Thyroid disease affects 6.6% of the general population. The liver is fundamental in metabolizing thyroid hormones, and hepatocytes are often affected in thyroid disease. We aimed to compare clinical and laboratory parameters among thyroid disease patients with alanine aminotransferase (ALT) levels above vs. below the upper tertile. Subjects and methods A retrospective cross-sectional analytical study was conducted in the endocrinology clinic at Polydoro Ernani de São Thiago University Hospital. Patients with thyroid disease between August 2012 and January 2014 were included in the study. Clinical and laboratory parameters were collected from medical records. Results One hundred patients were included, of which 14.0% were male, with a mean age of 49.1 ± 14.4 years. ALT levels ranged from 9 to 90 U/L, and the ALT upper tertile was defined as 0,64 times the upper normal limit (xUNL). Patients with ALT levels above the upper tertile exhibited a higher proportion of systemic arterial hypertension (SAH), a higher mean abdominal circumference and a higher frequency of elevated TSH levels than did patients with ALT levels below the upper tertile. In multivariate analysis, ALT ≥ 0.64 (xUNL) was independently associated with abdominal circumference (odds ratio [OR] = 0.087, 95% confidence interval [CI] 0012-0167, P = 0.022). ALT (xUNL) correlated positively with total cholesterol (r = 0.213, P = 0.042). Conclusions In patients with thyroid diseases, it was observed that those with ALT above the upper tertile are associated with abdominal circumference and ALT levels correlate with total cholesterol.

ABSTRACT

Introdução: Deficiência de vitamina D é reconhecida hoje como pandemia e fator de impacto no desenvolvimento de várias doenças, sendo recentemente relacionada à fisiopatologia da obesidade e da síndrome metabólica. Objetivos: Analisar os níveis séricos de vitamina D em pacientes obesos em avaliação pré-operatória para cirurgia bariátrica correlacionando-os com variáveis clínicas, laboratoriais e epidemiológicas. Métodos: Estudo observacional transversal, com 170 pacientes obesos grau 2 e 3 avaliados no ambulatório de cirurgia bariátrica do HU-UFSC em 2013. Foram coletados dados clínicos, epidemiológicos, antropométricos e laboratoriais. Resultados: A média de idade foi de 40 ± 10 anos, sendo a maioria do sexo feminino, caucasiana e habitante do litoral. O peso e o IMC médios foram 126,0 ± 24,2 kg e 48,0 ± 7,1 kg/m² respectivamente. As comorbidades mais prevalentes foram diabetes mellitus tipo 2 (24,7%) e hipertensão arterial sistêmica (55,3%). A média dos níveis de 25(OH)-vitamina D foi de 26,3 ± 8,4 ng/mL. Deficiência e insuficiência de vitamina D foram encontrados em 23,5 e 45,3% dos pacientes, respectivamente. Não houve correlação significativa entre os níveis de vitamina D e as demais variáveis estudadas, exceto o cálcio corrigido para a albumina. Conclusão: Os pacientes obesos em avaliação para cirurgia bariátrica neste serviço apresentam alta prevalência de deficiência/insuficiência de vitamina D. Estes níveis apresentaram correlação negativa estatisticamente significativa com o cálcio sérico corrigido, mas não com as demais variáveis estudadas.


Background: Vitamin D deficiency nowadays is recognized as a pandemic and important factor for development of a variety of diseases. It has been recently related to the physiopathology of obesity and metabolic syndrome. Objectives: To analyze serum levels of vitamin D in obese patients on preoperative evaluation for bariatric surgery and correlate them to clinical, laboratory and epidemiological variables. Methods: Cross-sectional observational study, including 170 patients with grade 2 and 3 obesity evaluated at the obesity outpatient clinic of the University Hospital (HU-UFSC) in 2013. Clinical, epidemiological, anthropometric and laboratory data were collected. Results: Mean age was 40 ± 10 years, the majority was females, Caucasian and living on the coast. Average weight and BMI were 126.0 ± 24.2 kg e 48.0 ± 7.1 kg/m² respectively. The most prevalent comorbidities were type 2 diabetes mellitus (24.7%) and hypertension (55.3%). Mean serum level of 25(OH)-vitamin D was 26.3 ± 8.4 ng/mL. Vitamin D deficiency and insufficiency were found in 23.5 and 45.3% of patients, respectively. There was no significant correlation between serum vitamin D levels and variables analyzed in this study, except albumin-corrected serum calcium. Conclusion: Obese patients evaluated for bariatric surgery in this service present a high prevalence of vitamin D deficiency/insufficiency. These levels were significantly negatively correlated with albumin-corrected serum calcium, but not with the other studied variables.

ABSTRACT

A disfunção endotelial é definida como sendo o conjunto de alterações encontradas na interface entre os elementos sanguíneos e os tecidos adjacentes. A disfunção endotelial é estudada em diversas condições, como aterosclerose, diabetes mellitus (DM), hipertensão arterial (HAS), hipercolesterolemia, entre outras. Esta revisão tem como objetivo descrever quais as evidências existentes, e/ou teorias propostas sobre a disfunção endotelial no contexto do diabetes mellitus tipo 2, contemplando não só a sua interferência na gênese da disfunção endotelial, como também sua relevância para o tratamento e até mesmo prevenção desta lesão, que sinaliza o início de muitas mazelas cardiovasculares dos pacientes com diabetes. Os mecanismos pelos quais o diabetes contribui para a disfunção endotelial não estão totalmente elucidados, mas é provável que a hiperglicemia seja um insulto importante para sua ocorrência. As concentrações de óxido nítrico derivado do endotélio (e-NO) muitas vezes têm sido descritas como normal nos pacientes diabéticos euglicêmicos, com tratamento otimizado, e com programas de exercício físico regular, porém, no estado hiperglicêmico a sua degradação e função se encontram alteradas. O conceito de disfunção endotelial como um mediador potencial para um aumento de risco de complicações cardiovasculares em pacientes com diabetes mellitus tipo 2 é bastante difundido na literatura, sendo que a restauração ou manutenção da função endotelial a partir de medidas não farmacológicas, principalmente pelo efeito do exercício físico, são aventadas como bastante importantes no desfecho final destes pacientes.


Endothelial dysfunction is defined as the set of changes found in the interface between blood elements and the surrounding tissues. Endothelial dysfunction is studied under various conditions such as atherosclerosis, diabetes mellitus, hypertension, hypercholesterolemia, among others. This review intends to describe the existing evidence and / or proposed theories about endothelial dysfunction in the context of type 2 diabetes mellitus, covering not only its interference in the genesis of endothelial dysfunction, as well as their relevance to the treatment and even prevention to this lesion that signalsthe beginning of many ills of cardiovascular patients with diabetes. The mechanisms by which diabetes contributes to endothelial dysfunction are not fully elucidated, but it is likely that hyperglycemia is a major insult to their occurrence. The concentrations of endothelium-derived nitric oxide have often been described as normal in the euglycemic diabetic patients with optimal treatment and programs of regular exercise, but in the hyperglycemic state, their degradation and function are altered. The concept of endothelial dysfunction as a potential mediator for increased risk of cardiovascular complications in patients with type 2 diabetes mellitus is widespread in the literature, and restoration or maintenance of endothelial function from non-pharmacological measures, especially the effect of exercise physical, are suggested as very important in the ending outcome of these patients.
