ABSTRACT
BACKGROUND: In multiple sclerosis (MS), treatment discontinuation leads to a higher risk of relapse, poorer quality of life and greater economic impact. OBJECTIVE: The objective of this work is to evaluate treatment discontinuation in MS, the reasons for this and the reasons for treatment resumption. METHODS: A French national Web-based survey was carried out between May and August 2011. A total of 602 MS patients answered a questionnaire on sociodemographic data, medical follow-up, disease-modifying therapies (DMTs), symptomatic treatments, care given, factors involved in treatment discontinuation and reasons for resuming treatment. RESULTS: Among 413 patients using DMTs, 54% have considered discontinuing their treatment, primarily because of anger (61%), side effects (61%) and fatigue (57%). Sixty-eight patients have actually discontinued their treatment because of side effects (43%), lack of observed outcomes (32%), exasperation (29%) or fatigue (29%). The reasons for symptomatic treatment discontinuation were fear of addiction (32%-46%) and lack of efficacy (28%-45%). Physiotherapy was discontinued because of fatigue (37%), stress (34%) or inefficiency (31%). According to patients, treatment discontinuation could have been prevented by psychological support, care team empathy and support from family. CONCLUSION: The major factor that could prevent treatment discontinuation is psychological support. Initiating and monitoring treatment in MS leads to emotional and personality changes, requiring adaptations that may improve compliance.
ABSTRACT
In clinically isolated syndrome (CIS), the detection of oligoclonal bands (OCBs) in cerebrospinal fluid (CSF) is critical for space dissemination validation when magnetic resonance imaging (MRI) diagnostic criteria are not fulfilled. However, lumbar puncture for CSF collection is considered relatively invasive. Previous studies have demonstrated applicability of OCB detection in tears to the diagnosis of multiple sclerosis (MS). The objective of the present study was to assess concordance between OCB detection in tears and in CSF. We have prospectively included patients with CIS and compared results of CSF and tear OCB detection by isoelectric focusing (IEF). Tears were collected using a Schirmer strip. We included 82 patients. For 69 of them, samples were analysable. OCBs were detected in CSF for 63.8% and in tears for 42% of patients. All patients with tear OCBs had CSF OCBs. We suggest that tear OCB detection may replace CSF OCB detection as a diagnostic tool in patients with CIS. This would circumvent the practice of invasive lumbar punctures currently used in MS diagnosis.
