This study assessed the direct economic burden of restless legs syndrome (RLS) among patients treated with dopamine agonists (DAs) using a large United States managed care database.
Retrospective database analysis.
Patients were required to have > or =1 prescriptions for a DA (i.e., pergolide, pramipexole, ropinirole) between 1/1/2005 and 12/31/2007 (date of first DA, or "index"); continuous enrollment for > or =6 months before and > or =12 months after index; > or =1 diagnosis of RLS, before and after index; and no diagnosis of Parkinson's disease. Study measures included annual all-cause and RLS-related costs by care setting (hospitalizations, emergency room, office, pharmacy, other, total) and treatment-pattern events (discontinuations, switches, adjunctive treatments, titrations).
A total of 7,796 patients met the inclusion criteria. About 70% of patients received ropinirole, and 30% received pramipexole at index. Approximately 91% had >1 RLS-related office visits, and patients filled an average of 6.5 RLS-related prescriptions (DAs, gabapentin, carbidopa/levodopa) during the 1-year follow-up period. Mean (SD) all-cause health care costs were $11,485 ($21,362) per patient, mostly due to multiple medical conditions occurring with RLS. RLS-related costs were 6.7% of total all-cause costs (mean [SD] $774 [$1,504]), consisting of office visits (16%), pharmacy (63%), and other costs (20%). Approximately 58% had a treatment-pattern event suggesting a dopamine-related side effect. Opioids were the most commonly used adjunctive therapy (13% of patients).
We found relatively low costs associated with RLS treatment. These findings should encourage expanding the coverage of treatment to reduce the suffering and costs associated with RLS.

    ABSTRACT: Dopamine dysregulation syndrome in Parkinson's disease has been attributed to dopamine replacement therapies and/or a lesion of the dopaminergic system. The dopaminergic neuronal loss targets the substantia nigra and the ventral tegmental area (VTA). We hypothesize that dopamine replacement therapy is responsible for the potential reinforcement effect in parkinson's disease by acting on the neuronal reward circuitry. Therefore this study was designed to explore the potential motivational effect of dopamine replacement therapy in bilateral VTA-lesioned animals. The posterior (p) VTA, which project to the nucleus accumbens (NAc) constitutes the major dopamine neuronal circuitry implicated in addictive disorders. Using the conditioned place preference (CPP) behavioral paradigm, we investigated the motivational effects of dopamine receptor agonists, and cocaine in rat with a 6-OHDA bilateral lesion of the pVTA. Amongst the dopamine receptor agonists used in this study only the D2R and D3R agonists (bromocriptine, PD128907 and pramipexole), induced a significant CPP in pVTA-lesioned animals. Dopamine receptor agonists did not induce behavioral sensitization in sham animals. Moreover, confocal D2R immunostaining analysis showed a significant increase in the number of D2R per cell body in the NAc shell of pVTA lesioned rats compared to sham. This result correlated, for the first time, the dopamine receptor agonists effect with DR2 overexpression in the NAc shell of pVTA-lesioned rats. In addition, cocaine, which is known to increase dopamine release, induced behavioral sensitization in sham group but not in dopamine deprived group. Thus, the later result highlighted the importance of pVTA-NAc dopaminergic pathway in positive reinforcements. Altogether these data suggested that the implication of the dopamine replacement therapy in the appearance of dopamine dysregulation syndrome in parkinson's disease is probably due to both neuronal degeneration in the posterior VTA and dopamine receptor sensitization in the dopamine depleted NAc.

    ABSTRACT: PURPOSE OF REVIEW: In recent years, there have been a number of advances in the field of restless legs syndrome (RLS) or Willis-Ekbom disease (WED). Here, we review recent studies pertaining to the diagnosis and clinical features, pathogenesis, and treatment of RLS/WED. RECENT FINDINGS: Recent studies have added a temporal dimension to RLS/WED epidemiology by examining both the incidence and persistence rates in different populations. Diagnostic criteria have been modified to increase sensitivity, and new guidelines take into account recently published studies of different drug classes. SUMMARY: Recent epidemiological findings have shown that RLS/WED is a common neurological disorder that affects up to 5% of the adult population in Western countries. In moderate and severe cases, RLS/WED has a strong impact on sleep and quality of life and can involve an increased cardiovascular risk. Diagnosis is made clinically by confirming the presence of the five essential criteria. However, in difficult cases objective tests such as the multiple suggested immobilization test (m-SIT) can be used. The pathophysiology is partially known, with several risk polymorphisms (BTBD-9 (BTB (POZ) domain containing 9), MEIS-1 (Meis homeobox 1), protein tyrosine phosphatase, receptor type, D, and others) playing an important role, along with dopaminergic and iron dysfunctions. The disorder frequently requires long-term treatment with low-dose dopamine agonists or α2δ ligands. Dopamine agonists are usually effective but the main complication, RLS/WED augmentation, can arise.
