ABSTRACT Objectives The objectives of this study were to evaluate the serum levels of adipokines in women with fibromyalgia with and without overweight/obesity, and to correlate the adipokines levels with clinical parameters associated with fibromyalgia and adipose tissue mass (body fat). Subjects and methods The study included 100 women divided into four groups: (a) fibromyalgia and overweight/obesity; (b) fibromyalgia and normal weight; (c) controls and overweight/obesity; and (d) controls and normal weight. Patients and controls were evaluated for clinical, anthropometric, and fibromyalgia-related parameters. Assessments included serum levels of leptin, adiponectin, monocyte chemoattractant protein-1 (MCP-1), and C-reactive protein (CRP). Levels of adipokines were further adjusted for fat mass. Results Fibromyalgia patients with overweight/obesity or normal weight had no differences in clinical parameters. Unadjusted leptin levels were lower in fibromyalgia patients than controls, a finding that was more remarkable in fibromyalgia patients with overweight/obesity. Leptin levels had no correlation with clinical parameters of fibromyalgia or inflammation markers (MCP-1 and CRP), and adiponectin levels showed no difference between groups. Conclusions No correlation was observed between adjusted leptin levels and clinical parameters of fibromyalgia. Patients with fibromyalgia and overweight/obesity presented lower levels of leptin than controls with overweight/obesity.

RESUMO Comparar a ingestão alimentar de mulheres com e sem fibromialgia e verificar se a ingestão alimentar das pacientes com fibromialgia interfere na sensação de dor e qualidade de vida.Participaram do estudo mulheres com fibromialgia (FM) atendidas no Ambulatório de Fibromialgia do Hospital de Clínicas/UFPR e para o grupo controle (CT) foram convidadas mulheres saudáveis. A coleta de dados foi feita de março a outubro de 2012. Para a avaliação do consumo alimentar foi usado o Registro Alimentar e os itens analisados foram: calorias totais, carboidratos, proteínas, lipídeos, vitaminas (A, C, B12, D e E) e minerais (folato, selênio, zinco, cálcio, ferro e magnésio). O software usado foi o Avanutri Online®. Para avaliação da qualidade de vida foi usado o Questionário de Impacto da Fibromialgia (FIQ) e limiar doloroso.Foram avaliadas 43 pacientes com FM e 44 mulheres saudáveis. O grupo CT apresentou consumo médio de nutrientes superior ao grupo FM, com exceção para o ferro. Entretanto, somente a ingestão calórica, carboidratos, proteínas e lipídeos em gramas, porcentagem de lipídios, vitamina A, E, B12, folato, selênio e cálcio foram estatisticamente significativas. No grupo FM houve correlação negativa entre vitamina E e FIQ e correlação positiva entre porcentagem de proteína e limiar doloroso.As mulheres com FM apresentaram ingestão qualitativamente e quantitativamente inferior ao grupo CT. Somente a vitamina E apresentou correlação com a qualidade de vida e a porcentagem de proteína na dieta com a sensação de dor.

ABSTRACT Objective: To compare the food intake of women with and without fibromyalgia and verify if the food intake of patients with fibromyalgia interferes with the pain and quality of life. Methods: Study participants were women with fibromyalgia (FM) seen in Fibromyalgia Outpatient Clinic, Hospital das Clínicas/UFPR and a control group (CT) with healthy women. Data collection was conducted from March to October 2012. For the assessment of food intake we used the Food Registration and analyzed items were: total calories, carbohydrates, proteins, lipids, vitamins (A, C, B12, D and E) and minerals (folate, selenium, zinc, iron, calcium and magnesium). The software used was Avanutri Online®. To evaluate the quality of life, the Fibromyalgia Impact Questionnaire (FIQ) and pain threshold were used. Results: 43 patients with FM and 44 healthy women were evaluated. CT group showed a mean consumption of nutrients greater than FM group except for iron. However, only caloric intake, carbohydrates, proteins and lipids in grams and percentage of lipids, vitamin A, E, B12, folate, selenium and calcium were statistically significant. In FM group there was a negative correlation between vitamin E and FIQ and a positive correlation between percentage of protein and pain threshold. Conclusion: Women with FM showed a lower qualitatively and quantitatively intake in comparison with CT group. Only vitamin E correlated with quality of life and percentage of protein in the diet with sensation of pain.

Introdução: A nefrolitíase é uma patologia frequente, com alta taxa de prevalência e recorrência, ocorrendo por processo multifatorial e complexo. Objetivo: Analisar as principais características dietéticas e metabólicas de pacientes com nefrolitíase e compará-los com grupo controle. Métodos: Estudo observacional, transversal, com 31 pacientes com nefrolitíase (NE) e 18 saudáveis. Na ingestão dietética, foram verificados sódio, cálcio, proteína, potássio, vitamina C, oxalato e a ingestão hídrica em ambos os grupos. Na avaliação metabólica, foi analisada excreção urinária de citrato e oxalato. Também foi avaliada presença de hipertensão arterial e Índice de Massa Corporal (IMC). Resultados: Quanto ao grupo NE, verificou-se que 45,2% apresentou alta ingestão de sódio e 100% de oxalato. Foi também observada baixa ingestão de cálcio em 93,5%, potássio em 100% e vitamina C em 94,9%. Com relação à proteína, apenas 12,5% apresentou ingestão normoproteica. Quanto à ingestão hídrica, 12,9% apresentou ingestão menor que 1 litro, 54,8% entre 1 a 2 litros, e 32,3% maior que 2 litros. Foi observada hipertensão arterial sistêmica em 64,5% desses pacientes e excreção adequada de citrato e oxalato em 90,5% deles. Não foi verificada diferença estatística significativa na ingestão alimentar, IMC, e excreção de oxalato entre os grupos. No entanto, o grupo NE apresentou maior excreção de citrato. Conclusão: Verificou-se nos dois grupos elevada prevalência de pacientes com sobrepeso, alta ingestão de oxalato e sódio, além de inadequação nas ingestões de cálcio, potássio e vitamina C. No grupo NE, foi observada alta ingestão proteica e maior excreção de citrato.

Introduction: Nephrolithiasis is a common condition with high prevalence and recurrence, occuring by a complex and multifactorial process. Objective: To analyze the main dietary and metabolic characteristics of patients with nephrolithiasis and compare them with a control group. Methods: A crosssectional study with 31 patients with nephrolithiasis (NE) and 18 healthy. By the dietary intake it were observed sodium, calcium, protein, potassium, vitamin C, oxalate and water intake in both groups. Metabolic assessment were analyzed in urinary excretion of oxalate and citrate. The presence of hypertension and body mass index (BMI) was also evaluated. Results: In the NE group, it was found that 45.2% had a high intake of sodium and 100% a high intake of oxalate. It was also observed a low calcium, potassium and vitamin C intake by 93.5%, 100% and 94.9% respectively. Regarding protein, only 12.5% had normal protein intake. Concerning water intake, 12.9% had an ingestion less than 1 liter, 54.8% between 1 and 2 liters and 32.3% higher than 2 liters. Hypertension was observed in 64.5% of patients and adequate excretion of oxalate and citrate in 90.5% of them. There was no statistically difference in food intake, BMI and oxalate excretion between groups. However, the NE group showed higher urinary citrate. Conclusion: It was found in both groups a high prevalence of overweight patients, a high intake of oxalate and sodium, in addition to inadequate intakes of calcium, potassium and vitamin C. The NE group showed high protein intake and increased excretion of citrate.
