Clinical impact of restless legs syndrome in patients with migraine: a 12-year, single-center, longitudinal study

AbstractAlthough many studies have indicated a significant association between migraine and restless legs syndrome (RLS), few long-term longitudinal studies have examined RLS in patients with migraine. We conducted a single-center, 12-year, longitudinal study of migraine patients and assessed whether RLS was present in 2010, 2017, or 2022 to evaluate its associations with clinical factors. Headache-related disability was assessed using the Migraine Disability Assessment (MIDAS). Sleep quality, daytime sleepiness, and depressive symptoms were assessed using the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS) and the Beck Depression Inventory-II (BDI-II), respectively. Of the 262 patients included at baseline (2010), 101 were available after 7 years (2017), and 74 were available after 12 years (2022). The RLS incidence rates were 13.7%, 20.8%, and 24.3% in 2010, 2017, and 2022, respectively. The RLS severity score did not significantly differ among the three time points. The persistent RLS group, defined as those who were positive for RLS at the last evaluation in addition to the first and/or second evaluations, had significantly higher MIDAS, BDI-II, PSQI and ESS scores than did the never RLS group, defined as those who did not exhibit RLS at any of the three time points. Our 12-year longitudinal study revealed significant impacts of RLS on the burden of patients with migraine.

Efficacy and Safety of Acupuncture for Restless Legs Syndrome in Patients with End-Stage Renal Disease: A Randomized-Controlled Trial at Hospital-Based Hemodialysis Center.

Background: Restless legs syndrome (RLS) is frequent in patients with hemodialysis (HD) and occurs predominantly in its most severe forms. The study was conducted to evaluate the efficacy and safety of acupuncture for RLS in patients with end-stage renal disease (ESRD) at hospital-based HD center. Methods: This single-blind, randomized controlled trial was performed on patients with HD and RLS who were randomly assigned to the experimental group and control group. Data were collected using the International Restless Legs Syndrome Rating Scale (IRLSRS), Insomnia Severity Index (ISI), and heart rate variability (HRV) records at baseline, after the therapeutic course (12 times/4 weeks), and 1-week follow-up. Result: A total of 47 patients were evaluated with IRLSRS score from 11 to 30 in this study. There were 41 patients enrolled in the study based on inclusion/exclusion criteria and allocated randomly into two groups. A total of 35 participants completed the trial, including 18 subjects in the experimental group and 17 subjects in the control group. The comparison of IRLSRS and ISI showed a significant reduction between two groups after acupuncture treatment (p = 0.002, p = 0.003). The ISI after 1-week follow-up also revealed significant decrease (p = 0.003). This HRV results showed that high frequency (HF%) increased significantly (p = 0.021) and low frequency (LF%) decreased significantly in the acupuncture group (p = 0.021). The generalized estimating equation showed that the IRLSRS improved by 2.902 points (p < 0.001) in the acupuncture group compared with the control group and by 1.340 points (p = 0.003) after 1-week follow-up. There were no adverse effects observed during HD in this study. Discussion: The authors conclude that acupuncture could effectively improve the symptoms of RLS significantly. The results from this study provide clinical evidence on the efficacy and safety of acupuncture to treat the patients with RLS at the HD center.

Restless legs syndrome in patients with obstructive sleep apnea: Association between apnea severity and symptoms of depression, insomnia, and daytime sleepiness

ObjectiveTo determine if the prevalence and severity of restless legs syndrome (RLS) varies with apnea severity and analyze differences between the sexes in terms of comorbid RLS with symptoms of depression, insomnia, and daytime sleepiness in patients with obstructive sleep apnea (OSA). MethodsSymptoms of depression, insomnia, and daytime sleepiness were defined as Patient Health Questionnaire–9 score ≥10, Insomnia Severity Index score ≥15, and Epworth Sleepiness Scale score ≥11. Multivariate logistic and linear regression analyses were conducted. ResultsIn 707 adults with OSA (85.1% males), 16.1% (n = 114) had comorbid RLS. The prevalence of RLS was markedly lower in those with moderate and severe OSA than in those with mild OSA. Similarly, the odds of RLS significantly decreased with increasing apnea-hypopnea index. After controlling for age and sex, in patients with comorbid RLS, the International RLS Study Group Rating Scale scores were negatively correlated with apnea-hypopnea index and a nadir peripheral oxygen saturation during sleep. The presence of RLS was more likely to be associated with symptoms of depression, insomnia, and daytime sleepiness after controlling for confounding variables, but only in men. ConclusionsRLS is frequently noted in combination with OSA, with a female preponderance. The severities of OSA and RLS may be negatively associated. In patients with OSA, sex-related differences in terms of comorbid RLS with symptoms of depression, insomnia, and daytime sleepiness warrant further investigations.

A randomized double-blind pilot study to evaluate the efficacy, safety, and tolerability of intravenous iron versus oral iron for the treatment of restless legs syndrome in patients with iron deficiency anemia.

Restless legs syndrome (RLS) is a neurological disorder that can have a profound effect on sleep and quality of life. Idiopathic RLS is associated with brain iron insufficiency despite normal peripheral iron stores. There is, however, a five- to six-fold increase in prevalence of RLS in patients with iron deficiency anemia (IDA). Several open-label trials have demonstrated symptomatic improvement in RLS following treatment of IDA using oral or intravenous iron supplementation. To date, there have been no randomized double-blind controlled trials of intravenous iron compared with oral iron for the treatment of RLS patients with IDA. In the current study, oral ferrous sulfate and ferumoxytol were compared for efficacy and speed of response for treatment of RLS occurring in patients with IDA. The planned recruitment for this study was 70 patients with RLS and IDA, to be randomly assigned 1:1 to oral or intravenous iron, using double-blind, double-dummy procedures. At Week 6, the primary outcomes of Clinical Global Impression-Improvement score and change from baseline in the International Restless Legs Syndrome Study Group rating scale score were assessed. Due to challenges, performing the clinical trial during the COVID-19 pandemic, final-week data were found missing for 30 patients. As a result, in order to maintain the prespecified statistical analysis, an additional 30 patients were recruited. Both IV and oral iron were associated with a marked improvement in RLS symptoms, with no statistically significant difference between treatment groups. No serious adverse events were observed in either treatment group.

Evaluation of Restless Leg Syndrome in Patients with Non-Dialysis Dependent Chronic Kidney Disease at Fatima Memorial Hospital Lahore: A Cross-sectional Study

Objective: To determine the occurrence of restless leg syndrome in individuals with non-dialysis-dependent chronic kidney disease.Study Design: A descriptive cross-sectional study.Place and Duration of Study: The study was carried out at the Outpatient Department (OPD) of Fatima Memorial Hospital, Lahore, Pakistan, from March 2020 to August 2020.Methods: A total of 280 CKD patients not dependent on dialysis were included in the study. The data were collected through interviews containing questions from international restless leg syndrome study group (IRLSSG). Patients were stratified into different stages according to the estimated glomerular filtration rate (eGFR). Restless leg syndrome was diagnosed by analyzing the responses of the interview marked by the examiner. Results: Among 280 patients, 15.7% (n=44) of chronic kidney disease patients were noted to have restless leg syndrome. The syndrome was significantly more frequent in females and was associated with higher CKD stages (Stage V &gt; Stage III and IV). There was no association with either age or BMI.Conclusion: Restless leg syndrome is more common in chronic kidney disease stage V as compared to lower chronic kidney disease stages (III &amp; IV). If untreated, it can affect patients' quality of life and increase the risk of cardiovascular activities.&#x0D; How to cite this: Basit MB, Sabir O, Shahid AH, Kanwal A, Qadri GA, Rizvi N.

Evaluation of Restless Leg Syndrome in Patients with Type 2 Diabetes Mellitus

Objective: To evaluate restless leg syndrome (RLS) in type 2 Diabetes Mellitus (T2DM) in Lahore.&#x0D; Materials and Methods: A cross-sectional study design was recruited for this study. Non-probability purposive sampling technique was used to select the patients in the study. The data was collected from the Pakistan Society for the Rehabilitation of Disabled (PSRD) Hospital and Hameed Latif Hospital Lahore. Patients diagnosed with T2DM with a maximum of 10 years, ages between 35 to 65 years, and patients who suffer from minor complications of diabetes mellitus were in cluded in the study. The RLS rating scale was used to assess the severity of restlessness in participants.&#x0D; Results: Out of 144 subjects, the frequency of the RLS was 71.5% and the majority was more in females as compared to male subjects. The female subjects have moderate severity of RLS while male subjects have mild severity of RLS.&#x0D; Conclusion: The frequency of RLS was high in patients with T2DM and females were more prone to RLS as compared to male subjects.&#x0D;

Restless leg syndrome in patients on hemodialysis

Background and Aim: Restless legs syndrome (RLS) is a prevalent neurological disease that is frequently misdiagnosed due to comparable signs and symptoms to other disorders such as diabetes, migraine, and cardiovascular disease. RLS may deteriorate with age, and it is more frequent in women than in males. The incidence of RLS varies from 6.6% to 80% in the general population. The present study aimed to assess the RLS in patients on hemodialysis. Patients and Methods: A questionnaire based study was conducted on 116 consecutive hemodialysis patients in the Department of Neurology and Nephrology of Institute of Kidney Diseases Hayatabad, Peshawar and PAF Hospital, Islamabad for the Duration from June 2022 to December 2022. Patients’ history included a history of drug, predialysis duration, and hemodialysis duration. Data was obtained using a standardized questionnaire that includes demographic variables such as personal history, family history, disease history, and smoking history.

Restless legs syndrome in patients with epilepsy: risk analysis, polysomnography, and quality of life evaluation.

Restless legs syndrome (RLS) is a circadian rhythm related sensorimotor disorder due to brain iron deficiency, with lesion sites at the putamen and substantia nigra. However, epilepsy is a disease with abnormal electric discharge from the cortex and can be triggered with iron disequilibrium. We designed a case-control study to discover the association between epilepsy and RLS. A total of 24 patients with epilepsy and RLS and 72 patients with epilepsy without RLS were included. Most of the patients underwent polysomnography and video electroencephalogram tests and took sleep questionnaires. We collected information on seizure characteristics, including general or focal onset, epileptogenic focus, current antiseizure medications, medically responsive epilepsy or refractory epilepsy, and nocturnal attacks. The sleep architectures of the two groups were compared. We analyzed the risk factors for RLS using multivariate logistic regression. Among the patients with epilepsy, the occurrence of RLS was associated with refractory epilepsy (OR 6.422, p = 0.002) and nocturnal seizures (OR 4.960, p = 0.005). Sleep parameters were not significantly associated with RLS status. Quality of life was significantly impaired in the group with RLS in both the physical and mental domains. Refractory epilepsy and nocturnal seizures were strongly correlated with RLS in patients with epilepsy. RLS should be considered a predictable comorbidity in patients with epilepsy. The management of RLS not only led to better control of the patient's epilepsy but also improved their quality of life.

Long-Term Effects of Positive Airway Pressure Treatment on Restless Legs Syndrome Severity in Obstructive Sleep Apnea Syndrome

To research how long-term positive airway pressure (PAP) therapy affects the severity of restless legs syndrome in patients with obstructive sleep apnea syndrome (OSASThe study included 320 individuals that were diagnosed with moderate and severe OSAS using polysomnography (PSG) and under PAP treatment. Among these patients, the demographic data of 72 patients who met the diagnostic criteria of restless legs syndrome (RLS) were analyzed. The patients were evaluated with the International RLS Study Group rating scale (IRLS) before and at the 12th month after PAP in the treatment of OSAS. The mean body mass index of the 72 patients with OSAS and RLS was 31.2 (±5.8), and their mean apnea-hypopnea index was 44.9±27.7. The prevalence of RLS in moderate and severe OSAS was 24%. There was a negative correlation between the IRLS score and mean oxygen saturation all night (r: -0.075), minimum oxygen saturation all night (r: -0.125), time spent below &amp;lt;90% saturation (r: -0.172), and sleep efficiency (r: 0.087) on PSG performed before PAP treatment, as well as a negative correlation between the IRLS score and weekly PAP use hours at the 12th month after PAP treatment (r: -0.316; p&amp;lt;0.001). The data obtained from this study suggest that the coexistence of OSAS and RLS is common and should not be overlooked in the diagnosis of comorbid diseases. Long-term PAP treatment is effective in reducing RLS symptoms. Further studies are needed on this subject.

Prevalence and severity of restless leg syndrome in patients with spinal cord injuries.

To determine the prevalence of restless leg syndrome in patients with spinal cord injury using a consensus criterion. The cross-sectional study was conducted from November 29, 2018, to February 28, 2021 at the departments of Neurology and Orthopaedic Surgery, King Edward Medical University, Mayo Hospital, Lahore, Pakistan, and comprised patients of either gender aged 18-80 years having spinal cord injuries. All the patients were interviewed using a 10-item questionnaire, and were assessed using the five-point consensus criteria of the International Restless Leg Syndrome Study Group. Data was analysed using SPSS 20. Of the 253 patients, 128(50.6%) were males and 125(49.4%) were females. The overall mean age was 38.6±14.2 years. Restless leg syndrome was present in 116(45.8%) patients, and 64(55.2%) of them were males (p>0.05). The mean duration of the symptoms was 18.9±16.9 months. Causes of spinal cord injury included metastasis 28(11.1%) multiple sclerosis 32(12.6%), neuromyelitis optica spectrum disorders 68(26.9%), tuberculous spondylitis 85(33.6%), trauma 24(9.5%) and viral myelitis 16(6.3%). Restless leg syndrome was prevalent in less than half the patients having spinal cord injury. It was more prevalent in males compared to females, but the difference was not significant.

Initial Cervical Spinal Cord Demyelinating Lesions are not Associated with Restless Legs Syndrome in Patients with Multiple Sclerosis.

This study aims to determine the prevalence and severity of restless legs syndrome (RLS) in patients with multiple sclerosis (MS) and its association with spinal cord lesions, fatigue, quality of life, and sleep disturbance. We recruited 222 consecutive MS patients admitted to MS outpatient clinic. Beck's Depression Inventory (BDI), Fatigue Severity Scale (FSS), Epworth Sleepiness Scale (ESS), Pittsburgh Sleep Quality Index (PSQI), and MS Quality of Life-54 (MSQoL-54) questionnaire scores of all patients were measured. Initial cervical spinal cord magnetic resonance imaging (MRI) of the patients at first clinical evaluation for diagnosis was reviewed for accompanying demyelinating lesions. RLS was diagnosed in 53 (23.87%) patients. RLS was associated with poor sleep, worse quality of life, increased fatigue, and depressive mood. The sleep quality index, FSS, and MSQoL-54 physical composite scores significantly correlated with RLS severity (P < 0.001, P = 0.001, P < 0.001, respectively). Of the 200 patients, 127 (63.5%) had spinal cord lesions. 22.83% of the patients with cervical spinal cord lesions had RLS comorbidity. We found no significant difference regarding spinal cord demyelinating lesions between RLS positives and negatives. (P = 0.77). In addition, having multiple spinal cord demyelinating lesions did not differ between the two groups (P = 0.84). Besides, the severity of RLS symptoms did not differ in patients who had a single cervical spinal lesion and those who had multiple lesions (P = 0.35). We have demonstrated the negative impact of comorbid RLS on fatigue, sleep quality, mood, and quality of life in MS patients. However, initial spinal cord lesions did not correlate with RLS comorbidity. The severity of RLS symptoms is associated with poor sleep and physical health.

Restless legs syndrome in patients with psoriasis: association with inflammation and sleep quality.

We aimed to evaluate if psoriasis associated with restless legs syndrome (RLS) due to its close relationship with metabolic disorders. This was a cross-sectional study in which the relationship between RLS and psoriasis was evaluated. Seventy consecutive psoriasis patients and 70 controls without any skin disorder were included in this study. Data including age, gender, body weight, height, and Psoriasis Area Severity Index (PASI) scores were recorded. Diagnosis of RLS was established using International RLS Study Group (IRLSSG) diagnostic criteria. International RLS Rating Scale (IRLSRS) was used to evaluate the severity of symptoms. Each participant completed forms of the Pittsburgh Sleep Quality Index (PSQI), the Epworth Sleepiness Scale (ESS), and the Dermatology Life Quality Index (DLQI). The RLS frequency in patients with psoriasis was 18.6% vs. 5.7% in the control group (P=0.018). In psoriasis patients, BMI, DLQI, IRLSRS, hemoglobin, ferritin, CRP, and uric acid levels were significantly higher than those of the controls. In psoriasis patients with RLS, PASI, DLQI, PSQI, IRLSRS scores, CRP level, and BMI were significantly higher, and hemoglobin level was significantly lower relative to the psoriasis patients without RLS. PASI score was the sole independent associate of RLS presence in psoriasis patients. Restless legs syndrome was significantly more common in psoriasis patients, and the presence of RLS was associated with significantly more severe psoriasis, more severe systemic inflammation, lower serum hemoglobin values, worse quality of life, and sleep quality.

Restless legs syndrome in patients with chronic low back pain.

Based on studies showing that both chronic low back pain (LBP) and restless legs syndrome (RLS) have similar pathophysiological mechanisms, we aimed to investigate the prevalence of RLS in patients with chronic LBP and to define which demographic and clinical features are prominent in those with LBP accompanied by RLS. One hundred and two eligible, volunteer participants with chronic LBP were enrolled in this study. Visual analog scale (VAS), the Oswestry Disability Index (ODI), Pittsburgh Sleep Quality Index, Beck Depression Inventory, and Short Form-36 scales were applied to the patients. All patients were evaluated face-to-face for RLS using the International RLS study group diagnostic criteria. Most of our patients were women (52%). The mean age was 40.96±13.34years and the mean disease duration was 46.16±41.98months. RLS was detected in 36 (35.3%) of the patients with LBP. It was found that the female gender was more dominant in patients with RLS and the difference was statistically significant (p < 0.001). The amount of coffee intake was significantly higher in patients with RLS compared to those without RLS (p = 0.001). The disease duration for LBP was significantly higher in the patients with RLS (p = 0.003). VAS score, ODI score, PUKI score, and Beck depression score were significantly higher in the RLS group (p value were 0.048, 0.040, 0.007, and 0.043, respectively). In the evaluation of quality of life, all parameters except role emotional limitations and mental health were found to be significantly worse in the RLS group.

Restless leg syndrome (RLS) in end stage renal disease

Introduction: End stage Renal Disease refers to permanent, irreversible loss of renal functions due to variety of underlying disorders. The condition is quite prevalent in our part of the world. The occurrence of Restless legs syndrome (RLS) in such patients, especially those on hemodialysis, surpasses that in the general population. RLS significantly blemishes their quality of life. The syndrome has subtle and nonspecific symptoms which are commonly neglected in dialysis centers. The study aims to determine the frequency of restless leg syndrome in patients of advanced renal disease.&#x0D; Methodology: A Cross Sectional Study conducted at Department of Medicine, Mayo Hospital Lahore from Dec 2018 to June 2019 (6 months). Patients of 20-80 years of age and of both genders, diagnosed as ESRD for ≥3 months were enrolled and evaluated for RLS. The condition was diagnosed as per International RLS Study Group (IRLSSG) criteria. The demographic data (age, gender, BMI and duration of symptoms) was recorded. History of smoking, alcohol use and chronicity of disease was also noted. Mean and percentages were calculated. Chi-Square test was applied. p-value of ≤0.05 was taken as significant.&#x0D; Results: Total of 75 patients were enrolled. Males were 54 (72.0%) while 21 (28.0%) were females. Mean age was 47.3±13.1(22-73) years. RLS was observed in 29 (38.7%) cases. Age, gender, duration of illness, smoking and alcohol consumption had no significant association with RLS (p values 0.642, 0.669, 0.208, 0.245, 0.565, 0.745) respectively.&#x0D; Conclusion: Restless legs syndrome is frequently encountered condition in ESRD patients.

Prevalence of insomnia and restless legs syndrome in patients with upper airway stimulation therapy and effects on treatment outcomes

ObjectiveThis study aims to explore the prevalence of insomnia and restless legs syndrome (RLS) and the possible effects of these conditions on treatment adherence and outcomes in patients with upper airway stimulation (UAS) therapy for the treatment of obstructive sleep apnea. MethodsConsecutive patients who underwent UAS system implantation were retrospectively studied. Patients without insomnia or RLS, insomnia, RLS, and both insomnia and RLS were compared. The apnea-hypopnea index (AHI), in-lab UAS titration data, Epworth Sleepiness Scale (ESS), and adherence to UAS therapy were compared. ResultsSixty-four patients who had UAS implantation and completed post-implant in-lab UAS titration were identified. Insomnia was present in 47%, RLS in 28%, and both insomnia and RLS in 14%. During in-lab titration, the AHI improved for all groups and did not differ across groups. The arousal index on in-lab titration was higher in patients with both RLS and insomnia compared to those without these conditions. At the time of the in-lab titration, the hours of UAS therapy usage were reduced for patients with RLS (4.7 ± 1.9 h/night, p = 0.027) compared to those without RLS (6.0 ± 2.0 h/night). The ESS was higher in patients with RLS compared to those without RLS at in-lab titration. ConclusionInsomnia and RLS are common in patients using UAS therapy. A decrease in UAS usage and higher ESS were present in patients with RLS. Further research evaluating the long-term effects of insomnia and RLS in UAS therapy usage and benefit is needed.
