Restless leg syndrome in systemic lupus erythematosus: Associations with disease activity, quality of life and depression. Sleep Med 2024; 121:111-116. [PMID: 38959717 DOI: 10.1016/j.sleep.2024.06.020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Revised: 06/05/2024] [Accepted: 06/21/2024] [Indexed: 07/05/2024]
Abstract
OBJECTIVES The aim of this study was to determine the prevalence of restless leg syndrome (RLS) among patients with SLE, describe their clinical characteristics, examine its impact on health-related quality of life (HRQoL), and evaluate its association with depression. METHODS A total of 124 SLE patients were recruited, with data on demographics, and clinical features collected. RLS diagnosis was based on the international RLS study group criteria, while depression was assessed by the patient health questionnaire. HRQoL was assessed by a disease-specific validated questionnaire, the LupusQoL, pain intensity was examined through the pain visual analogue scale, and disease activity was evaluated via the patient global assessment. These variables were compared between SLE patients with RLS and without RLS using t-tests or Wilcoxon and the chi-square test of independence for categorical variables. A p-value ≤0.05 was considered statistically significant. RESULTS Among the SLE patients (mean age 48, 87.1 % women), 32 % had RLS. The SLE patients with RLS were found to have a longer delay in diagnosis (1 vs 0.5 years; p = 0.019) and were less likely to be employed (65 % vs 45 %, p = 0.040) compared to non-RLS patients. In addition, RLS patients were more likely to have coexisting Major Depressive Disorder (MDD) (p = 0.019), higher levels of pain (p = 0.006) and disease activity based on patient global assessment (p = 0.014). Further, most of the domains of LupusQoL were significantly lower in the RLS patients group suggesting a worse HRQoL. CONCLUSION RLS was present in one-third of the SLE cohort, significantly impairing HRQoL and correlating with depression, higher pain, and increased disease activity. These findings underscore the importance of early RLS detection and management in SLE patients.

Abstract
BACKGROUND Restless legs syndrome (RLS) is a sensorimotor disorder that is prevalent in chronic inflammatory conditions. RLS prevalence, risk factors, and impact on sleep in CF have not been extensively characterized to date. METHODS An initial cohort was examined, including 75 persons with CF (PwCF) and 75 control subjects, to look at the prevalence and severity of RLS. A second validation cohort of 191 PwCF was then enrolled from two CF centers to examine risk factors for RLS. A diagnosis of RLS was made according to the International RLS Study Group (IRLSSG) criteria. Sleep quality was identified using the Pittsburgh sleep quality index (PSQI). Epworth sleepiness scale (ESS) was used to measure daytime sleepiness. We then analyzed laboratory and clinical risk factors and sleep symptoms for potential risk factors for RLS. RESULTS In the initial cohort, 36 % of PwCF had RLS, and 9 % of these had significant RLS. In contrast, only 15 % of controls had RLS, and none had significant RLS. In the second larger validation cohort with 191 subjects, a comparable prevalence of RLS was identified. Higher hemoglobin A1c, use of SSRI/SNRI medications, worse PSQI and ESS sleep quality scores, lower lung function, and higher antibiotic usage were significantly associated with a diagnosis of RLS. By multivariate multinominal logistic regression analysis, higher HbA1c and worse PSQI global sleep quality scores were independent predictors of significant RLS. CONCLUSIONS RLS is highly prevalent in CF. Higher HbA1c and poor sleep quality, signified by higher PSQI, were each independent predictors of RLS.

Abstract
Restless legs syndrome (RLS) is a chronic movement disorder characterized by an urge or need to move the limbs, usually associated with uncomfortable sensations in the legs and sleep disorders. In general, two clinical forms of RLS are described: primary and secondary. Although primary RLS has a familial component, the underlying mechanism is still not fully understood but seems to be related to abnormalities in the dopaminergic and glutamatergic pathways of the central nervous system. The secondary forms of the syndrome are associated with iron deficiency, renal failure, pregnancy, diabetes mellitus, peripheral neuropathy, and several rheumatologic disorders such as rheumatoid arthritis and Sjögren's syndrome. In a few clinical trials, an increased frequency of RLS has been reported in patients with spondyloarthritis. In this report, a case of coexistence of spondyloarthritis and RLS is presented, showing satisfactory improvement with conservative treatment and additionally adding naproxen. Anemia of chronic disease occurring in rheumatic diseases, and associated iron deficiency may contribute to the development of RLS.

Abstract
INTRODUCTION Restless leg syndrome (RLS) is a neurological disorder characterized by an uncontrollable desire to move legs along with abnormal sensations, particularly at night, which can lead to sleep disturbance. RLS may mimic rheumatic diseases or can be associated with them, hence their identification and treatment are important to improve sleep quality and overall quality of life in rheumatic diseases. METHODS We conducted a search of the PubMed, SCOPUS, and EMBASE databases to identify studies reporting a prevalence of RLS in patients with rheumatic disease. Two authors independently screened, selected, and extracted the data. Heterogeneity was assessed using I2 statistics and random effect method of the meta-analysis was used to synthesize the results. RESULTS Out of 273 unique records, 17 eligible studies including 2406 rheumatic patients were identified. RLS prevalence (95% CI) among patients of rheumatoid arthritis, systemic lupus erythematosus, osteoarthritis, fibromyalgia and ankylosing spondylitis are found to be 26.6% (18.6 34.6); 32.5% (23.1-41.9), 4.4% (2.0-6.8), 38.1% (31.3-45.0) and 30.8% (23.48-39.16) respectively. RLS prevalence was similar for males and females. CONCLUSION Our study indicates a high prevalence of RLS in patients with rheumatic diseases. Early detection and treatment of RLS in patients with rheumatic conditions could be beneficial in improving their overall health and quality of life.

Abstract
Background and aims
In this study, we aimed to compare the prevalence of restless legs syndrome (RLS) between primary Sjögren syndrome (PSS) patients and the healthy population and investigate the relationships between RLS and insomnia status, anxiety, depression, neuropathic pain, and lower extremity pain. Our case-control study, included 55 patients aged 18–65 who were diagnosed with PSS based on the 2016 ACR/EULAR criteria and 60 healthy controls aged 18–65. The pain levels of the participants were evaluated using the pain DETECT Questionnaire, the lower-extremity visual analog scale, and an algometer, all participants were screened for fibromyalgia syndrome, and their psychiatric parameters were evaluated with the Beck Depression Inventory and the Beck Anxiety Inventory. Insomnia status was assessed using the Insomnia Severity Index. The cases in the PSS group with and without restless legs syndrome were compared.
Results
While the rate of RLS in the PSS group was 26.7%, that in the control group was found as 9%, and the difference between the two groups was significant (p < 0.05). The severity of RLS in the PSS group was found to be significantly higher in comparison to that in the control group (p < 0.05). The PSS group had significantly higher lower-extremity pain, fibromyalgia, insomnia, depression, anxiety, and pain scores, as well as a significantly higher mean number of painful points, than the control group (p > 0.05). In the results of the multivariate regression analysis, depression and insomnia scores were identified as independent predictors for the presence of RLS in PSS cases (p < 0.05).
Conclusions
We found the prevalence and severity of restless legs syndrome higher in the primary Sjögren syndrome patients compared to the healthy participants in the control group. We identified depression and insomnia as independent predictors of the presence of restless legs syndrome in primary Sjögren syndrome cases.

Abstract
Background Background The study aims to determine the frequency of restless legs syndrome (RLS) in patients with ankylosing spondylitis (AS) and the relationship between the International Restless Legs Syndrome Study Group Rating Scale (IRLSSG-RS) score and anemia.
Material and Methods It was a case-control study that included 106 patients with AS and 106 age- and sex-matched healthy controls in the rheumatology clinic of a training and research hospital. The patients were divided into two groups according to their hemoglobin levels. A hemoglobin level lower than 12 g/dL in women and less than 13 g/dL in men was the criterion for anemia.
Results Although the frequency of RLS was higher in AS patients than in control groups, there was no significant difference in the IRLSSG-RS score between AS patients and control groups. 23 (57.5%) of the AS patients with anemia had RLS, and the IRLSSG-RS score was 21.3±5.7. Of the AS patients without anemia, 11 (16.7%) had RLS, and the IRLSSG-RS score was 15±6. Statistically significant differences between AS patients with and without anemia regarding RLS frequency and IRLSSG-RS score were found. The IRLSSG-RS scores of AS patients were negatively correlated with serum iron and hemoglobin level.
Conclusions Patients with AS had a higher RLS frequency than the control group; AS patients with anemia had a higher RLS and IRLSSG-RS score than AS patients without anemia. Also, a negative and significant correlation was found between the IRLSS-RS score and serum iron and hemoglobin levels in AS patients.

Abstract
Preventing synovial fibroblast (SF) migration into the adjacent cartilage is a desirable therapeutic target in rheumatoid arthritis (RA). As previous studies demonstrated that RASF and SF from osteoarthritis (OA) patients express dopamine receptors (DR), aim of the present study was to investigate the impact of dopamine on mobility of fibroblasts from patients with chronic arthritides. Synovial tissue and fibroblasts were obtained from RA and OA patients. Immunohistochemistry was performed for all DR-subtypes in the invasion zone. Migration- and motility-assays were performed under DR-stimulation. Cytokines were evaluated using ELISA. Expression of DRs was evaluated by flow cytometry, and DR activation was measured by xCELLigence real-time analysis.
All DRs were expressed in RA invasion zone. Migration and motility of RASF and OASF were increased after DR stimulation in patients ≤ 75 years old. Synovial fibroblasts from older RA patients (> 75 years old) expressed lower levels of D1-, D2- and D4-DR than patients ≤ 75 years old. DR activation was not altered in older patients. Our results suggest a possible involvement of dopamine on migration of fibroblasts from arthritis patients. Therefore, the synovial dopaminergic pathway might represent a potential therapeutic target to interfere with progressive joint damage in RA patients.

Abstract
Clinical evidences suggest a causal relationship between rheumatoid arthritis (RA) and the dopaminergic system, and several studies described an alteration of the disease in patients treated with dopaminergic agents. Despite these interesting results, potential direct effects of dopamine on RA have not been intensively considered until the last decade. Recent studies confirm a direct effect of dopamine on the systemic immune response as well as on bone remodeling and on joint inflammation, both in humans and in different animal models of arthritis. While more research is necessary to accurately determine the effect of dopamine in RA, these results are encouraging and support a possible use of dopaminergic drugs for the treatment of arthritis in the future. Moreover, they point out that dopaminergic agents use to treat comorbidities, might influence the immune response and the disease progression in RA patients. This review summarizes the current knowledge about the effects of dopaminergic drugs on RA and describes the potential of dopaminergic drugs as future therapeutic strategy in arthritis.

Abstract
INTRODUCTION Primary Sjögren's syndrome is the third most common systemic autoimmune rheumatic disease, following rheumatoid arthritis and systemic lupus erythematosus, and results in dryness, fatigue, discomfort and sleep disturbances. Sleep is relatively unexplored in primary Sjögren's syndrome. We investigated the experiences of sleep disturbances from the viewpoint of primary Sjögren's syndrome patients and their partners and explored the acceptability of cognitive behavioural therapy for insomnia. METHOD We used focus groups to collect qualitative data from 10 patients with primary Sjögren's syndrome and three partners of patients. The data were recorded, transcribed verbatim and analysed using thematic analysis. RESULTS Five themes emerged from the data: (a) Experience of sleep disturbances; (b) variation and inconsistency in sleep disturbances; (c) the domino effect of primary Sjögren's syndrome symptoms; (d) strategies to manage sleep; (e) acceptability of evidence-based techniques. Sleep disturbances were problematic for all patients, but specific disturbances varied between participants. These included prolonged sleep onset time and frequent night awakenings and were aggravated by pain and discomfort. Patients deployed a range of strategies to try and self-manage. Cognitive behavioural therapy for insomnia was seen as an acceptable intervention, as long as a rationale for its use is given and it is tailored for primary Sjögren's syndrome. CONCLUSION Primary Sjögren's syndrome patients described a range of sleep disturbances. Applying tailored, evidence-based sleep therapy interventions may improve sleep, severity of other primary Sjögren's syndrome symptoms and functional ability.

Abstract
Objective: Restless legs syndrome (RLS) is a common sensory motor disorder. RLS an urge to move the extremities that may be accompanied by dysesthesias, and significantly affects quality of life of affected patients. The frequency of RLS is higher in different systemic inflammatory diseases. Familial Mediterranean fever (FMF) is an inherited inflammatory disease characterized by attacks of polyserositis, arthritis, and fever. The prevalence of RLS in patients with FMF is unknown. This study aimed to evaluate the prevalence rate of RLS in a sample of patients with FMF and compare this prevalence with that of a matched normal population. Method: A total of 60 patients with FMF and 60 healthy controls were studied. All participants underwent a neurological examination. Diagnostic criteria as proposed by the International Restless Legs Syndrome Study Group (IRLSSG) were used to define RLS. The IRLSSG rating scale for the severity of RLS was applied to determine the severity of symptoms. Results: The prevalence of RLS was not significantly different between patients and controls. Although the mean International Restless Legs Syndrome Rating Scale (IRLSRS) scores tended to be higher in patients compared with controls, this difference was not significant. When each item of the severity scale was compared between the two groups, significantly higher scores were found in some items of the IRLSRS in patients with FMF compared with controls. Conclusion: According to this result, RLS symptoms in patients with FMF were more frequent and lasted longer than those in controls.

Abstract
Restless legs syndrome (RLS), a common neurological sensorimotor disorder in western countries, has gained more and more attention in Asian countries. The prevalence of RLS is higher in older people and females. RLS is most commonly related to iron deficiency, pregnancy and uremia. The RLS symptoms show a significant circadian rhythm and a close relationship to periodic limb movements (PLMs) in clinical observations, while the pathophysiological pathways are still unknown. The diagnostic criteria have been revised in 2012 to improve the validity of RLS diagnosis. Recent studies have suggested an important role of iron decrease of brain in RLS pathophysiology. Dopaminergic (DA) system dysfunction in A11 cell groups has been recognized long ago from clinical treatment and autopsy. Nowadays, it is believed that iron dysfunction can affect DA system from different pathways and opioids have a protective effect on DA system. Several susceptible single nucleotide polymorphisms such as BTBD9 and MEIS1, which are thought to be involved in embryonic neuronal development, have been reported to be associated with RLS. Several pharmacological and non-pharmacological treatment are discussed in this review. First-line treatments of RLS include DA agents and α2δ agonists. Augmentation is very common in long-term treatment of RLS which makes prevention and management of augmentation very important for RLS patients. A combination of different types of medication is effective in preventing and treating augmentation. The knowledge on RLS is still limited, the pathophysiology and better management of RLS remain to be discovered.

Abstract
We aimed to investigate the frequency of restless legs syndrome (RLS) and the associations between RLS and quality of sleep and life in patients with ankylosing spondylitis (AS). One hundred and eight AS patients and 64 controls were included in this study. Demographics, clinical, and laboratory data were recorded. The presence of RLS was determined with face-to-face interview by an experienced neurologist based on the International RLS Study Group criteria. RLS severity was evaluated using International RLS Study Group rating scale. Sleep quality and insomnia severity were assessed by Pittsburgh sleep quality index (PSQI) and insomnia severity index (ISI), respectively. Disease-related quality of life was evaluated by AS quality of life questionnaire (ASQoL). The frequency of RLS was significantly higher in AS patients than in controls (36.4 vs. 14.0 %, p = 0.004). RLS severity score for AS patients was significantly higher than that for controls (p = 0.03). The AS patients had higher scores in the subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleep medication domains of PSQI, and also total PSQI and ISI than controls (p < 0.05, for all). ASQoL scores were higher in AS patients with RLS compared to those without RLS (p < 0.001). RLS severity was observed to be independently associated with total PSQI, ISI and ASQoL (p < 0.05, for all). As RLS may adversely affect the sleep and quality of life in AS patients, clinicians should be aware of RLS for early diagnosis and management in AS patients.

Abstract
AIM Our aim was to evaluate the relationship between the prevalence and severity of restless legs syndrome (RLS) and the anemia in patients with systemic lupus erythematosus (SLE). METHODS This was a case-control study which was conducted at the rheumatology clinic of a university affiliated hospital, including 62 patients with SLE and 62 age- and sex-matched healthy controls. The patients were divided into two groups in terms of their hemoglobin levels. The criterion for anemia was hemoglobin level lower than 12 g/dL in females and 13 g/dL in males. RESULTS Nineteen patients (30.6%) in the patient group were diagnosed with RLS, and International RLS Study Group Rating Scale (IRLSSG-RS) score was 10.7 ± 9.5 (median:10.0 [range:0.0-30.0]). Three subjects (4.8%) in the control group had RLS, and the IRLSSG-RS score was 0.7 ± 3.3 (median:0.0 [range:0.0-18.0]). The prevalence of RLS and the IRLSSG-RS score were higher in the patient group than those in the control group (P < 0.001). Ten SLE patients (50%) with anemia had RLS, and their IRLSSG-RS score was 14.5 ± 9.9 (median:21.0 [range:11.0-30.0]). Nine SLE patients (21.4%) without anemia had RLS and their IRLSSG-RS was 9.0 ± 8.9 (median:21.0 [range:11.0-24.0]). Significant differences were present in the prevalence of RLS and the IRLSSG-RS score between SLE patients with and without anemia (P = 0.024, P = 0.044, respectively). CONCLUSION The present study demonstrated that the prevalence of RLS was higher in patients with SLE than that of the normal population. Results of this study also suggested that anemia was associated with higher frequency of and more severe RLS in patients with lupus.

Abstract
PURPOSE OF REVIEW Recently published literature indicates that sleep disorders present with medical comorbidities quite frequently. The coexistence of a sleep disorder with a medical disorder has a substantial impact for both the patient and the health system. RECENT FINDINGS Insomnia and hypersomnia are highly comorbid with medical conditions, such as chronic pain and diabetes, as well as with various cardiovascular, respiratory, gastrointestinal, urinary and neurological disorders. Restless legs syndrome and periodic leg movement syndrome have been associated with iron deficiency, kidney disease, diabetes, and neurological, autoimmune, cardiovascular and respiratory disorders. Rapid eye movement behaviour disorder has been described as an early manifestation of serious central nervous system diseases; thus, close neurological monitoring of patients referring with this complaint is indicated. SUMMARY Identification and management of any sleep disorder in medical patients is important for optimizing the course and prognosis. Of equal importance is the search for undetected medical disorder in patients presenting with sleep disorders.

Abstract
The prevalence of restless legs syndrome (RLS) and its association with the clinical features of Behçet's disease (BD) has not previously been elucidated. The inflammatory character, central nervous system involvement and neuropathies of BD led to this investigation of RLS risk in BD patients. A total of 116 BD patients and 104 healthy control subjects were included; seven BD patients were excluded because of concurrent diseases, pregnancy or alcohol misuse that might cause RLS symptoms, and the remaining 109 BD patients were included in the analysis. The prevalence of RLS was significantly higher in patients with BD (32/109; 29.4%) than in controls (5/104; 4.8%). No significant differences were found between BD patients with and without RLS with regard to the clinical features of BD. RLS severity positively correlated with age in BD patients. In conclusion, BD-related RLS should be considered in symptomatic RLS secondary to rheumatological disorders and BD patients should be examined for RLS. Further studies are needed to clarify the pathogenetic mechanisms underlying BD-related RLS.

Abstract
PURPOSE OF REVIEW Although restless legs syndrome (RLS) is a disorder recognized in the medical literature since the 17th century, there have only recently been significant clinical and scientific advances in diagnosis, epidemiology and understanding the disorder, mainly due to the advent of dopaminergic treatment. RECENT FINDINGS Recent discoveries have uncovered the iron-dopamine connection in RLS and the basic dopaminergic pathology related to the RLS symptoms. These have led to new understanding of the morbidity of RLS and the many conditions associated with RLS, which have also supported new approaches to treatment. These developments are each briefly described here. SUMMARY Although there has been progress in understanding, diagnosing and treating RLS, it remains an underdiagnosed and undertreated condition severely impairing functioning of patients with moderate-to-severe disease. Much work is needed to improve on current, as well as other novel therapies.

Abstract
Restless legs syndrome (RLS) is characterized by a compelling, often insatiable, need to move the legs, accompanied by unpleasant sensations located mainly in the ankles and calves. Because symptoms are brought on by inactivity, distress intrudes upon everyday, sedentary activities such as plane travel, car rides, and attending school, meetings, or the theatre. Symptoms show a diurnal preference for the evening and night, so disruption of sleep onset or maintenance is particularly common. RLS is associated with both lower ratings of quality of life and higher rates of cardiovascular disease. Four common genetic loci associating to RLS have recently been identified, but the molecular pathways by which they increase risk for RLS have yet to be determined. Both sensory (RLS) and motor (periodic limb movements of sleep) symptoms are responsive to dopaminergic medications, yet clear delineation of dopaminergic pathology has not emerged. Brain iron is reduced in many, but not all, patients with RLS. First-line treatment for RLS includes agents acting at D(2) and D(3) dopamine receptors.

Abstract
Restless legs syndrome (RLS) is a common neurological condition, frequently idiopathic, sometimes associated with specific disorders such as iron deficiency. We investigated RLS prevalence in celiac disease (CD), an autoimmune disease characterized by several features such as malabsorption-related iron deficiency anemia and peripheral neuropathy. We screened a population of 100 adult CD patients for CD features, iron metabolism, clinical and neurological conditions, and enrolled 100 age- and sex-matched controls in the general population. RLS was ascertained in CD patients and controls by both the presence of the four essential International RLS Study Group diagnostic criteria and neurological examination. The International RLS Study Group rating scale was used to measure RLS severity. We found a 31% prevalence of RLS in the CD population that was significantly higher than the prevalence in the control population (4%; P < 0.001). The average severity of RLS in CD population was moderate (17 +/- 6.5). In the CD population, no significant correlation was found between RLS and either gluten-free diet or iron metabolism, despite hemoglobin levels were significantly lower in CD patients with RLS than without RLS (P = 0.003). We found no correlation between RLS and other possible causes of secondary RLS, including signs of peripheral neuropathy, pregnancy, end-stage renal disease, and pharmacological treatments.Our study broadens the spectrum of neurological disorders associated with CD and indicates that RLS should be sought for in all patients with CD.

Abstract
BACKGROUND Extraintestinal manifestations of Crohn's disease (CD) have not previously included the central nervous system (CNS). Restless legs syndrome (RLS) is a CNS disorder that is either idiopathic or secondary to a number of diseases. The aim of this study was to determine if RLS was associated with CD because both are associated with iron deficiency, inflammation, and bacterial overgrowth. METHODS Consecutive CD outpatients (N = 272) were prospectively surveyed at 4 centers for criteria for RLS. Incidence (having RLS at any point in time), prevalence (having RLS at time of survey), clinical characteristics, risk factors, and potential qualitative relationship between RLS and gastrointestinal symptoms were queried. RESULTS The incidence of RLS in patients with CD was 42.7%. Prevalence was 30.2% compared with 9% of spouses. CD patients with and without RLS had a mean age of 46.8 versus 42.6 years, small intestine involvement in 77.9% versus 66.7%, colon involvement in 39.7% versus 63.2%, and prior iron deficiency anemia in 49.3% versus 33.1%. There was no difference between the CD groups with respect to current iron deficiency, RLS family history, or rare prevalence of concomitant RLS disorders. In 91.8% of patients with RLS and CD, RLS started during or after the onset of CD diagnosis. Among 73 patients with RLS, 67 (44.5%) stated there was a relationship between qualitative RLS symptom improvement with overall CD symptom improvement. CONCLUSIONS These results demonstrate that RLS occurs frequently in CD and appears to be a possible extraintestinal manifestation. The potential relationship of RLS with CD activity warrants further investigation.

Abstract
Restless legs syndrome (RLS) is a condition characterized by discomfort at rest and urge to move focused on the legs. RLS may occur as an idiopathic, often hereditary condition (primary RLS), or in association with medical conditions (secondary RLS) including iron deficiency, uremia, and polyneuropathy. Current understanding of the pathophysiology of RLS points to the involvement of three interrelated components: dopaminergic dysfunction, impaired iron homeostasis, and genetic mechanisms. The diagnosis of RLS is made according to the consensus criteria by a National Institutes of Health panel: 1) an urge to move the legs, usually accompanied by uncomfortable sensations; 2) beginning or worsening during rest; 3) relieved by movement; and 4) worse, or only occurring, in the evening or at night. The differential diagnosis of RLS aims to: 1) distinguish RLS from other disorders with RLS-like symptoms and 2) identify secondary forms, with investigation of underlying diseases. The treatment of RLS demands a clinical evaluation to rule out and cure causes of secondary RLS, including iron supplementation when deficient, and to eliminate the triggering factors. The presence of neuropathy should be especially investigated in nonhereditary, late-onset RLS, in view of a possible treatment of the underlying disease. The first line treatment for idiopathic RLS is represented by dopamine agonists, in particular nonergot-derived ropinirole and pramipexole, whereas ergot dopamine agonists (cabergoline and pergolide) are no longer in first-line use given the risks of cardiac valvulopathy. Although no comparative trials have been published, a meta-analysis of pramipexole versus ropinirole suggests differences in efficacy and tolerability favoring pramipexole.
