PurposeThe pregnancy is accepted as an independent risk factor for restless legs syndrome/Willis-Ekbom disease (RLS/WED). The neutrophil-to-lymphocyte ratio (NLR) was recently reported in the pathophysiology of RLS/WED. In this report, we investigated the relationship between the presence of RLS/WED and the levels of NLR in pregnancy.MethodsWe included 268 pregnant women attending routine prenatal visits; 148 women had RLS/WED, and 120 women without RLS/WED were the control group. A pre-formed questionnaire was administered to all participants regarding demographic characteristics, habitual behaviors, detailed medical history and questions about RLS/WED including disease duration, severity, and family history. Laboratory investigations were performed in all participants regarding the complete blood count, NLR, fasting blood glucose, blood urea nitrogen, creatinine, ferritin, and total iron binding capacity.ResultsNLR was significantly higher in pregnant women with RLS/WED as compared to those without it (3.9±0.9 versus 3.5±1.1, p=0.039). Smoking was also significantly more common in pregnant women with RLS/WED (p=0.022). NLR significantly increased as the gestational period progressed, even after the adjustments for age, BMI, and smoking (p=0.035). Higher NLR in pregnant women with RLS/WED was especially prominent in the 3rd trimester, although the difference was not significant.ConclusionThese results may suggest that an increased inflammation demonstrated by the increased NLR, may, in part, play a role in higher prevalence of RLS/WED in pregnancy, especially in late gestational weeks (Tab. 2, Fig. 1, Ref. 34).
