Postprandial hypoglycemia is a common complication of bariatric surgery. It is usually caused by late dumping syndrome, but a few other causes have already been described, including insulinoma and noninsulinoma pancreatogenous hypoglycemic syndrome (NIPHS). Considering that NIPHS is a recently described syndrome and is also very rare, therapeutic approaches are still not consensual. We report the case of a 26-year-old woman who was submitted to bariatric surgery and presented episodic postprandial hypoglycemic episodes after 16 months. Fasting C-peptide, insulin, and glucose were normal. Because of the possibility of NIPHS, clinical treatment was initiated with verapamil and acarbose, leading to a significant reduction of hypoglycemic episodes and also their severity. Surgery is the most common approach to NIPHS. However, in cases of mild or moderate symptoms, it is important to consider the possibility of pharmacological treatment. This approach may result, at least for some time, in an amelioration of symptoms without the need of an aggressive procedure.
Adolescent obesity is becoming a health problem in both developed and developing countries. Antiobesity drug therapy is not currently indicated for the treatment of adolescent obesity and remains investigational at this time. The aim of this study was to determine the efficacy and safety of sibutramine in obese adolescents. A randomized, double-blind, placebo-controlled trial, enrolling 60 adolescents, aged 14-17 yr, for 6 months was conducted. In the first month, all patients received placebo and a hypocaloric diet plus exercise orientation. For the next 6 months, participants received either sibutramine or placebo. Patients assigned to sibutramine group lost an average of 10.3 +/- 6.6 kg, and patients in placebo group lost 2.4 +/- 2.5 kg (P < 0.001). The mean body mass index reduction was significantly greater in the sibutramine group (3.6 +/- 2.5 kg/m(2)) than in the placebo group (0.9 +/- 0.9 kg/m(2); P < 0.001). No participant withdrew because of adverse events, and no difference in blood pressure or heart rate was noted between groups. There were no changes in echocardiographic parameters. In conclusion, sibutramine plus diet and exercise induced significantly more weight loss in obese adolescents.
BackgroundComorbid depression in diabetes has been suggested as one of the possible causes of an inadequate glycemic control. The purpose of this study was to investigate the association between major depression and the glycemic control of type 2 diabetes mellitus (T2DM).MethodsSeventy T2DM patients were evaluated. They underwent a psychiatric examination using the following instruments: Structured Clinical Interview for DSM-IV and Beck Depression Inventory. The diabetes status was assessed in the short-term (glycemia, glycated hemoglobin) clinical control.ResultsThe presence of current depression was observed in 18.6% (13/70). In addition, type 2 diabetes patients who displayed depression evidenced higher levels of glycated hemoglobin (8.6 ± 2.0 vs. 7.5 ± 1.8; p = 0.05) when compared to those who did not exhibit a mood disorder.ConclusionsIn our sample, the presence of depression seems to impact on the short-term control of T2DM. The authors discuss the clinical utility of these findings in the usual treatment of diabetes.
BackgroundSince the first position statement on diabetes and cardiovascular prevention published in 2014 by the Brazilian Diabetes Society, the current view on primary and secondary prevention in diabetes has evolved as a result of new approaches on cardiovascular risk stratification, new cholesterol lowering drugs, and new anti-hyperglycemic drugs. Importantly, a pattern of risk heterogeneity has emerged, showing that not all diabetic patients are at high or very high risk. In fact, most younger patients who have no overt cardiovascular risk factors may be more adequately classified as being at intermediate or even low cardiovascular risk. Thus, there is a need for cardiovascular risk stratification in patients with diabetes. The present panel reviews the best current evidence and proposes a practical risk-based approach on treatment for patients with diabetes.Main bodyThe Brazilian Diabetes Society, the Brazilian Society of Cardiology, and the Brazilian Endocrinology and Metabolism Society gathered to form an expert panel including 28 cardiologists and endocrinologists to review the best available evidence and to draft up-to-date an evidence-based guideline with practical recommendations for risk stratification and prevention of cardiovascular disease in diabetes. The guideline includes 59 recommendations covering: (1) the impact of new anti-hyperglycemic drugs and new lipid lowering drugs on cardiovascular risk; (2) a guide to statin use, including new definitions of LDL-cholesterol and in non-HDL-cholesterol targets; (3) evaluation of silent myocardial ischemia and subclinical atherosclerosis in patients with diabetes; (4) hypertension treatment; and (5) the use of antiplatelet therapy.ConclusionsDiabetes is a heterogeneous disease. Although cardiovascular risk is increased in most patients, those without risk factors or evidence of sub-clinical atherosclerosis are at a lower risk. Optimal management must rely on an approach that will cover both cardiovascular disease prevention in individuals in the highest risk as well as protection from overtreatment in those at lower risk. Thus, cardiovascular prevention strategies should be individualized according to cardiovascular risk while intensification of treatment should focus on those at higher risk.
A presença de depressão no paciente com diabetes mellitus (DM) parece relacionar-se a alterações no curso clínico da doença. O objetivo deste trabalho é realizar uma revisão sistemática sobre a associação entre o DM e depressão. Foi realizada uma pesquisa bibliográfica utilizando as bases de dados MEDLINE e LILACS para identificar artigos relevantes, publicados entre 1990 e 2001, que avaliassem esta associação. Foram analisadas informações referentes à prevalência, ao impacto e ao tratamento da depressão no DM. A prevalência de depressão no DM variou de 0 a 60,5%. Sintomas depressivos relacionaram-se a um pior controle glicêmico, a um aumento e a uma maior gravidade das complicações clínicas, a uma piora da qualidade de vida e ao comprometimento de aspectos sociais, econômicos e educacionais ligados ao DM. O tratamento da depressão está relacionado à melhora dos níveis glicêmicos, podendo contribuir para um melhor controle de diversos aspectos relacionados ao DM. The presence of depression in a patient with diabetes mellitus (DM) seems to be related to changes in the clinical course of the disease. The purpose of this study is to perform a systematic review on the association of DM and depression. A bibliographic search was performed using the MEDLINE and LILACS databases to identify relevant articles, published from 1990 to 2001, which evaluate this relationship. Information concerning prevalence, impact and treatment of depression in DM were analyzed. The prevalence of depression varied from 0 to 60.5%. The presence of depressive symptoms were associated with a poor glycemic control, an increase in the number and severity of clinical complications, a worse quality of life and impairment of social, educational and economic aspects related to DM. The treatment of depression is associated with an improvement in glycemic levels, which may contribute to a better control of several aspects related to DM.

Hypoglycemic episodes after obesity surgery are not always related to dumping syndrome. The persistence of hypoglycemia in spite of nutritional counseling should raise the possibility that there may exist other causes. Insulinoma, the most common cause of endogenous hyperinsulinemia, should be investigated in these patients, since it is a tumor that can be cured.
The aim of this study was to translate into Portuguese and to assess the reliability of an instrument for the diagnosis of diabetic distal polyneuropathy (DPN). The process for translation and adaptation into Portuguese of the Neuropathy Symptom Score (NSS) and the Neuropathy Disability Score (NDS) was performed following internationally standardized procedures. The instruments were applied by 2 raters in 57 consecutive subjects. Spearman correlation was used to evaluate the reliability and Cronbachs' alpha to evaluate the internal consistency of the items. Both, ECN and ESN, showed a good reliability (r= 0.77, p< 0.0001 and r= 0.76, p< 0.0001, respectively). ESN showed a good internal consistency (alpha= 0.74). The diagnosis of DPN, defined as the combination of the two scores (ECN+ESN) also showed a good reliability (r= 0.63, p< 0.0001). The Portuguese versions of the ESN and the ECN seem to be adequate for the diagnosis of DPN in this population.
