Background: Multiple sclerosis (MS) is a complex disease with new drugs becoming available in the past years. There is a need for a reference tool compiling current data to aid professionals in treatment decisions. Objectives: To develop an evidence-based clinical practice guideline for the pharmacological treatment of people with MS. Methods: This guideline has been developed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology and following the updated EAN recommendations. Clinical questions were formulated in Patients–Intervention–Comparator–Outcome (PICO) format and outcomes were prioritized. The quality of evidence was rated into four categories according to the risk of bias. The recommendations with assigned strength (strong and weak) were formulated based on the quality of evidence and the risk-benefit balance. Consensus between the panelists was reached by use of the modified nominal group technique. Results: A total of 10 questions were agreed, encompassing treatment efficacy, response criteria, strategies to address suboptimal response and safety concerns and treatment strategies in MS and pregnancy. The guideline takes into account all disease-modifying drugs approved by the European Medicine Agency (EMA) at the time of publication. A total of 21 recommendations were agreed by the guideline working group after three rounds of consensus. Conclusion: The present guideline will enable homogeneity of treatment decisions across Europe.

Recurrent oral and genital ulcers are the most frequent problem in the management of the Behçet syndrome. Uncontrolled experience suggests that thalidomide may help prevent recurrences of these ulcers. To determine the efficacy of two thalidomide dosages in the treatment of mucocutaneous lesions of the Behçet syndrome. Randomized, double-blind, placebo-controlled trial. Specialist outpatient clinic for the Behçet syndrome in Turkey. 96 male patients with the Behçet syndrome who primarily had mucocutaneous lesions without major organ involvement. Thalidomide, 100 mg/d or 300 mg/d, or placebo for 24 weeks. Sustained absence of any oral and genital ulceration during treatment (complete response) and changes in the number of mucocutaneous lesions. An additional evaluation was done 4 weeks after treatment ended. A complete response occurred in 2 of the 32 patients (6% [95% CI, 0.8% to 20.8%]) receiving thalidomide, 100 mg/d; in 5 of the 31 patients (16% [CI, 5.5% to 33.7%]) receiving thalidomide, 300 mg/d; and in none of the 32 patients (0% [CI, 0% to 10.9%]) receiving placebo (P = 0.031). The suppressive effect of thalidomide with either dosage was evident at 4 weeks for oral ulcers (P < 0.001) and at 8 weeks for genital ulcers (P < 0.001) and follicular lesions (P = 0.008). This effect persisted during treatment but diminished rapidly after treatment was discontinued. Both thalidomide dosages led to significant increases in the number of erythema nodosum lesions during the first 8 weeks of treatment (P = 0.03). Polyneuropathy developed in 4 patients (1 in the 100-mg/d group and 3 in the 300-mg/d group); in 3 of these patients, the condition was diagnosed after the trial had ended. Thalidomide is effective for treating the oral and genital ulcers and follicular lesions of the Behçet syndrome. A dosage of 100 mg/d is as effective as a dosage of 300 mg/day.

Neuro-Behçet’s disease (NBD) is one of the more serious manifestations of Behçet’s disease (BD), which is a relapsing inflammatory multisystem disease with an interesting epidemiology. Though NBD is relatively uncommon, being potentially treatable, neurologists need to consider it in the differential diagnosis of inflammatory, infective, or demyelinating CNS disorders. Evidence-based information on key issues of NBD diagnosis and management is scarce, and planning for such studies is challenging. We therefore initiated this project to develop expert consensus recommendations that might be helpful to neurologists and other clinicians, created through an extensive literature review and wide consultations with an international advisory panel, followed by a Delphi exercise. We agreed on consensus criteria for the diagnosis of NBD with two levels of certainty in addition to recommendations on when to consider NBD in a neurological patient, and on the use of various paraclinical tests. The management recommendations included treatment of the parenchymal NBD and cerebral venous thrombosis, the use of disease modifying therapies, prognostic factors, outcome measures, and headache in BD. Future studies are needed to validate the proposed criteria and provide evidence-based treatments.
