RESUMO
Introdução: A síndrome metabólica (SM) é preditor independente de doença cardiovascular, a principal causa de mortalidade no Lúpus Eritematoso Sistêmico (LES). Não existem dados sobre os principais fatores associados à SM em pacientes jovens na pré-menopausa, população mais afetada pelo LES. Objetivo: Avaliar a prevalência da SM em mulheres jovens na pré-menopausa com LES e identificar fatores relacionados a doença e à terapêutica que contribuem para a SM, utilizando a análise pelo propensity score. Materiais e Métodos: Foram avaliadas 103 pacientes com LES (critérios do American College Rheumatology 1997) na pré-menopausa, com idade inferior a 40 anos de idade. Foram selecionadas 35 mulheres saudáveis como controles, com menos de 40 anos de idade, sem doenças crônicas e autoimunes. Os critérios de exclusão foram idade inferior a 18 anos, menopausa e gravidez. Parâmetros clínicos, laboratoriais e de terapêutica foram avaliados. A definição da SM foi feita de acordo com os recentes critérios do Joint Interim Statement de 2009. Análise multivariada utilizou a regressão de Poisson e a análise pelo propensity score foi realizada para o controle das variáveis de confusão. Resultados: A prevalência de SM foi mais elevada no grupo LES (22,3 vs. 5,7%; p=0,03), assim como o risco cardiovascular pelo Systematic Coronary Risk Evaluation (SCORE) (1,4 ± 0,8 vs. 1,1 ± 0,4; p=0,01). Hipertensão arterial sistêmica (42,7 vs. 2,9%; p<0,0001) e circunferência abdominal aumentada (83,5 vs. 37,1%; p < 0,0001) foram critérios da SM mais frequentes no LES, que apresentou maiores Homeostasis Model Assessment Index (HOMA-IR) (1,8 + 0,9 vs. 1,3 + 1,0; p=0,0008). Não houve diferença significativa quanto à idade, tempo de doença e pontuação no Systemic Lupus International Collaborative Clinics (SLICC/ACR DI) entre os grupos LES com e sem SM. No grupo com LES com SM, os escores do Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) foram significativamente mais elevados...
ABSTRACT
Background: There are no data about the main factors associated with metabolic syndrome (MetS) in young premenopausal systemic lupus erythematosus (SLE) patients. Objectives: The aim of the study was to evaluate the frequency of MetS and disease- or therapy-related factors in premenopausal young SLE patients. Methods: 103 premenopausal SLE patients with age less than 40 years old were selected and compared to 35 healthy premenopausal age-matched female. MetS was defined according to the 2009 Joint Interim Statement. Results: A higher frequency of MetS (22.3 vs. 5.7%, p=0.03) was observed in SLE group. MetS-SLE patients presented higher SLE Disease Activity Index (SLEDAI) scores (5.9 ± 7.6 vs. 1.9 ± 2.7, p=0.006), more frequently previous (73.9 vs. 51.2%, p=0.05) and current renal disease (34.8 vs. 10.0%, p=0.008), higher current prednisone dose (20 [0-60] vs. 5 [0- 60] mg/dl, p=0.018) and cumulative prednisone dose (41.48 + 27.81 vs. 24.7 + 18.66 g, p=0.023) than those without MetS. Chloroquine was less frequently used in MetS-SLE patients (65.2 vs. 90.0 %, p=0.008). In multivariate analysis, only current chloroquine use (prevalence ratio [PR]=0.29; 95% CI 0.13-0.64) and cumulative prednisone were associated with MetS (PR=1.02; 95% CI 1.01- 1.04). Further estimated prevalence analysis identified that antimalarial use promoted continuous decrease in the progressive MetS prevalence associated with glucocorticoid cumulative dose. Conclusion: The prevalence of MetS in premenopausal young adult SLE patients is high, and is mainly affected by steroid and antimalarial therapies. Chloroquine has protective effect on the prevalence of MetS in these patients and this benefit counteracts the deleterious effect of glucocorticoid in a dose dependent manner.
