Objectives. Restless Legs Syndrome is a movement disorder characterized by unpleasant sensations in the legs described as a burning, tingling, etc. Symptoms become worse in the evening and are relieved by moving the limbs. The idiopathic form of the disease is associated with a lack of dopamine, and the secondary form is associated with iron deficiency anemia, pregnancy, and kidney disease. The aim of this study was to investigate the incidence of iron deficiency anemia in pregnant women and non-pregnant women suffering from RLS. Methods. The study was conducted on a sample of 231 pregnant women aged 18–50. The pregnant women were interviewed at the outpatient clinic of the Department of Gynaecology and Obstetrics. This study also included a control group of 231 age-compatible non-pregnant women. Women who met the international criteria for diagnosing the syndrome filled in a sociodemographic questionnaire. Results. A statistically significant association between the existence of iron deficiency anemia and RLS in the sample of the examined women was proven (p < 0.001). It was also shown that RLS is more frequent in a sample of anemic pregnant women than non-anemic pregnant women (p = 0.008). Conclusion. Iron deficiency anemia is related with RLS. Pregnant women with RLS are more likely to be anemic than pregnant women without RLS.

Objectives: The aim of this cross-sectional study was to examine the correlation between gestational age and number of previous pregnancies in group of pregnant women with restless legs syndrome and the connection of restless legs syndrome with family history positive versus family history negative group of pregnant and non-pregnant women. Methods: Four hundred and sixty-two women were involved in this study: 231 pregnant women and the same number of non-pregnant women of compatible age as a control group. We defined restless legs syndrome as presence of International Restless Legs Syndrome Study Group criteria. During the face-to-face interview with the researcher, respondents answered questions about duration of pregnancy, number of previous pregnancies and family history of restless legs syndrome. Results: Before the 16th week of pregnancy, restless legs syndrome appeared in 7.1% of pregnant women and after 16 weeks of pregnancy in 22.6% of them (t = 2.07, p = 0.039). Restless legs syndrome appeared in 11.4% of pregnant women without restless legs syndrome in the family and in 74.2% of pregnant women who did have restless legs syndrome in the family (t = 7.67, p < 0.001). It was also found that among non-pregnant women with a family history of restless legs syndrome, 42.9% had restless legs syndrome, and among those without a family history of restless legs syndrome, only 4.9% had restless legs syndrome (t = 3.49, p = 0.001). No statistically significant correlation between restless legs syndrome and number of previous pregnancies in pregnant women has been found. Conclusion: Our study confirmed a higher frequency of restless legs syndrome in women pregnant for 17 or more weeks and in both pregnant and non-pregnant women with a positive family history of this syndrome. We have not proven a connection between restless legs syndrome and multiparity.

Background: Restless legs syndrome (RLS) is very common among pregnant women; its prevalence corresponds to parity and occurs more frequently in the later stages of pregnancy. It is associated with numerous adverse pregnancy outcomes such as an increased risk of Caesarean section, preeclampsia, insomnia, and depression. Medical treatment of RLS during pregnancy is challenging considering the risks to both the mother and fetus. Case Description: In this report, we describe the case of a 44-year-old, seventh-time multiparous woman with a positive family history of RLS who presented with severe symptoms in her 24th week of pregnancy. She has had symptoms of RLS in every pregnancy thus far, usually starting in the second trimester, with an ineffective therapeutic response to diazepam and uncomfortable sensations, which usually resolve spontaneously a few weeks after delivery. After replacing diazepam with low-dose clonazepam, the patient reported complete disappearance of unpleasant sensations in her legs, with a significant improvement in her quality of life. Conclusions: A low dose of clonazepam is a good therapeutic option for the treatment of RLS during pregnancy and, if necessary, can also be considered the therapy of choice during lactation.
