ABSTRACT

Summary Introduction: The purpose of this study was to evaluate the prevalence of peripheral polyneuropathy (PPN) in subjects with grade II and III obesity (Ob-II,III) and metabolic syndrome (MetS) but without diabetes and to investigate possible associated factors. Method: A cross-sectional study was performed in non-diabetic Ob-II,III,MetS patients using the Michigan Neuropathy Screening Instrument (MNSI) to assess the presence of PPN. Results: A total of 24 of 218 non-diabetic Ob-II,III,MetS patients had PPN. Based on univariate analysis, serum levels of LDL-cholesterol (p=0.046) were significantly associated with PPN, while serum triglycerides (p=0.118) and low HDL-cholesterol (p=0.057) showed a tendency toward this association. On a Poisson regression analysis, when the three possible associations were included, low HDL-cholesterol (p=0.047) remained independently associated. Conclusion: In non-diabetic Ob-II,III,MetS patients, PPN defined by the MNSI showed a high prevalence and was associated with low levels of HDL-cholesterol. In order to diagnose that complication, neurological evaluation should be performed in these patients.


Resumo Objetivo: Avaliar a prevalência da polineuropatia periférica (PNP) em indivíduos obesos graus II e III com síndrome metabólica (Ob-II,III,SM) sem diabetes e buscar possíveis fatores associados. Método: Em um estudo transversal, realizado em indivíduos Ob-II,III,SM e sem diagnóstico de diabetes, o Instrumento de Screening de Michigan (MNSI) foi utilizado para avaliar a presença de PNP. Resultados: Um total de 24 de 218 pacientes Ob-II,III,SM e sem diabetes tinham PNP. Quando observamos as associações com PNP em uma análise univariada, níveis séricos de LDL-colesterol (p=0.046) estiveram significativamente associados e houve também uma tendência à associação com níveis séricos de triglicerídeos (p=0.118) e baixo HDL-colesterol (p=0.057). Em uma análise de regressão de Poisson, quando as três possíveis associações foram incluídas, baixo HDL-colesterol (p=0.047) manteve-se independentemente associado. Conclusão: Em pacientes Ob-II,III,SM, mas sem diabetes, a PNP definida pelo MNSI tem uma prevalência elevada e está associada a baixos níveis de HDL-colesterol. Para diagnóstico dessa complicação, recomenda-se realizar o exame neurológico desses pacientes.

ABSTRACT

Summary Objectives: the aim of this study was to evaluate the efficacy of Roux-en-Y Gastric Bypass (RYGB), compared with nonsurgical treatment (NS group), as an instrument for inducing remission of co-morbidities related to Metabolic Syndrome (MetS) in patients with Obesity, grades 2 and 3 (Ob2,3). Methods: two hundred and fifty eight Ob2,3 patients were selected in a retrospective analysis and included in a case control study. MetS was defined as described by the International Diabetes Federation. One hundred and twenty-nine of these patients underwent RYGB (S group), and 129 were assessed as an NS group. Results: at baseline, S and NS groups did not differ in BMI, age, female sex and prevalence of MetS (p>0.05). For the S group the outcomes were a reduction in BMI of 38.1% (p<0.001), waist circumference of 28.6% (p<0.001), fasting plasma glucose of 10.5% (p<0.001), serum LDL-cholesterol of 21.9% (p<0.001) and of 85% in the number of patients with MetS (p<0.001). For the NS group, only a decrease of 4.12%(p=0.047) in triglyceride levels and of 5.9%(p=0.031) in Diastolic Blood Pressure was observed. In the NS group, 98.6% of the patients continued to have MetS. The number needed to treat (NNT) with surgery to resolve one case of MetS was 1.2 (CI 95%: 1.1 - 1.4). Conclusion: in the real world, in the South of Brazil, compared with NS treatment and after 1 year of observation, RYGB is highly effective for decreasing the prevalence of MetS. .


Resumo Objetivo: o objetivo deste estudo foi avaliar a eficácia do bypass gástrico em Y de Roux (BGYR), em comparação a um tratamento não cirúrgico (grupo NC), como instrumento para induzir remissão da síndrome metabólica (SMet) em pacientes com obesidade graus 2 e 3 (Ob2, 3). Métodos: duzentos e cinquenta e oito pacientes com Ob2,3 foram selecionados para análise retrospectiva em estudos de caso e controle. SMet foi definida como descrita pela Federação Internacional de Diabetes. Dos pacientes, 129 foram submetidos ao BGYR (grupo C), e 129 formaram o grupo NC. Resultados: antes dos tratamentos, os grupos C e NC não diferiram em IMC, idade, sexo feminino e prevalência de SMet (p>0,05). No grupo C, houve uma redução no IMC de 38,1% (p<0,001), circunferência da cintura de 28,6% (p<0,001), glicemia de jejum de 10,5% (p<0,001), LDL colesterol sérico de 21,9% (p<0,001) e em 85% dos casos de SMet (p<0,001). As diferenças observadas no grupo NC foram uma diminuição nos níveis de triglicérides, de 4,12% (p=0,047), e na pressão arterial diastólica, de 5,9% (p=0,031). No grupo NC, 98,6% dos pacientes persistiram com SMet. O número necessário para tratar (NNT) com a cirurgia, para resolver um caso de SMet, foi de 1,2 (IC 95%: 1,1 - 1,4). Conclusão: em um mundo real, no Sul do Brasil, em comparação ao tratamento NS e após 1 ano de observação, BGYR foi altamente eficaz para diminuir a prevalência de SMet. .
