Abstract

Restless legs syndrome (RLS) is a distressing and common neurological disorder that may have a huge impact in the quality of life of those with frequent and intense symptoms. Patients complain of unpleasant sensations in the legs, at or before bedtime, and feel an urge to move the legs, which improves with movement, such as walking. Symptoms start with the patient at rest (e.g. sitting or lying down), and follow a circadian pattern, increasing during the evening or at night. Many pharmacological intervention are available for RLS, including drugs used to treat Parkinson's disease (L-Dopa and dopaminergic agonists), epilepsy (anticonvulsants), anxiety (benzodiazepines), and pain (opioids). Dopaminergic drugs are those most frequently used for treatment of RLS, but some patients do not respond effectively and require other medication. Opioids, a class of medications used to treat severe pain, seem to be effective in treating RLS symptoms, and are recommended for patients with severe symptoms, because RLS and pain appear to share the same mechanism in the central nervous system. All available drugs are associated to some degree with side effects, which can impede treatment. Opioids are associated with adverse events such as constipation, tolerance, and dependence. This justifies the conduct of a systematic review to ascertain whether opioids are safe and effective for treatment of RLS. To asses the effects of opioids compared to placebo treatment for restless legs syndrome in adults. We searched the Cochrane Central Register of Controlled trials, CENTRAL 2016, issue 4 and MEDLINE, EMBASE, and LILACS up to April 2016, using a search strategy adapted by Cochraneto identify randomised clinical trials. We checked the references of each study and established personal communication with other authors to identify any additional studies. We considered publications in all languages. Randomised controlled clinical trials of opioid treatment in adults with idiopathic RLS. Two review authors independently screened articles, independently extracted data into a standard form, and assessed for risk of bias. If necessary, they discussed discrepancies with a third researcher to resolve any doubts. We included one randomised clinical trial (N = 304 randomised; 204 completed; 276 analysed) that evaluated opioids (prolonged release oxycodone/naloxone) versus placebo. After 12 weeks, RSL symptoms had improved more in the drug group than in the placebo group (using the IRLSSS: MD -7.0; 95% CI -9.69 to -4.31 and the CGI: MD -1.11; 95% CI -1.49 to -0.73). More patients in the drug group than in the placebo group were drug responders (using the IRLSSS: RR 1.82; 95% CI 1.37 to 2.42 and the CGI: RR1.92; 95% ICI 1.49 to 2.48). The proportion of remitters was greater in the drug group than in the placebo group (using the IRLSSS: RR 2.14; 95% CI 1.45 to 3.16). Quality of life scores also improved more in the drug group than in the placebo group (MD -0.73; 95% CI -1.1 to -0.36). Quality of sleep was improved more in the drug group measured by sleep adequacy (MD -0.74; 95% CI -1.15 to -0.33), and sleep quantity (MD 0.89; 95% CI 0.52 to 1.26).There was no difference between groups for daytime somnolence, trouble staying awake during the day, or naps during the day. More adverse events were reported in the drug group (RR 1.22; 95% CI 1.07 to 1.39). The major adverse events were gastrointestinal problems, fatigue, and headache. Opioids seem to be effective for treating RLS symptoms, but there are no definitive data regarding the important problem of safety. This conclusion is based on only one study with a high dropout rate (moderate quality evidence).

Attention Score in Context

This research output has an Altmetric Attention Score of 18. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 24 June 2019.
All research outputs
#904,846
of 13,538,736 outputs
Outputs from Cochrane database of systematic reviews
#2,810
of 10,639 outputs
Outputs of similar age
#25,067
of 260,410 outputs
Outputs of similar age from Cochrane database of systematic reviews
#50
of 143 outputs
Altmetric has tracked 13,538,736 research outputs across all sources so far. Compared to these this one has done particularly well and is in the 93rd percentile: it's in the top 10% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 10,639 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 21.1. This one has gotten more attention than average, scoring higher than 73% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 260,410 tracked outputs that were published within six weeks on either side of this one in any source. This one has done particularly well, scoring higher than 90% of its contemporaries.
We're also able to compare this research output to 143 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 65% of its contemporaries.
