The proposed referral parameters have proven useful when applied in primary care in identifying patients with AS/pre-radiographic axial SpA among young to middle-aged patients with chronic low back pain.

Objective: To examine the potential therapeutic effect of methotrexate 20 mg given weekly as subcutaneous injections to 20 patients with ankylosing spondylitis refractory to nonsteriodal antirheumatic drugs. Patients and methods: 20 patients with ankylosing spondylitis, a mean Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score of 5.6 (range 4-9.3) and predominantly axial manifestations were treated with weekly 15 mg methotrexate subcutaneously for 4 weeks, which was then increased to 20 mg subcutaneously for the next 12 weeks. Clinical outcome assessments included, among others, BASDAI score physical function, spinal mobility, patients' and physicians' global assessment (visual analogue scale), peripheral joint assessment, quality of life (Short Form 36) and C reactive protein. The primary end point of the study was a 20% improvement on the ASsessments in Ankylosing Spondylitis (ASAS 20) scale. Results: Using an intention-to-treat analysis, ASAS 20 was achieved in only 25% of patients. An ASAS 40 response was achieved in 10% of patients, and no patient reached an ASAS 70 response or the ASAS criteria for partial remission. For the mean BASDAI score, no change was observed between baseline and week 16 (baseline 5.6 v week 16, 5.6). No improvement was observed in any of the clinical parameters or C reactive protein, except a small but non-significant decrease in the number of swollen joints. Conclusions:In this open study, methotrexate did not show any benefit for axial manifestations in patients with active ankylosing spondylitis beyond the expected placebo response.

NR2 glutamate receptor antibodies in the CSF may be more useful for the diagnosis of NPSLE than is such measurement in serum samples. Furthermore, whether IgG anti-NR2 glutamate receptor antibodies are produced in situ in the brain or cross the blood-brain barrier and how they cross the bloodbrain barrier if they are produced outside the brain are issues that need to be elucidated.

In this multicentre, double-blind, parallel group study, we evaluated the efficacy and safety of continuous treatment with itraconazole, 200 mg daily for 3 months, in comparison with itraconazole pulse therapy, 400 mg daily 1 week per month for 3 months, in the treatment of toe-nail onychomycosis. The study included 129 patients with distal subungual onychomycosis of the toe-nails, confirmed by microscopy and positive for dermatophyte culture; 65 received continuous treatment and 64 received pulse therapy. Patients were followed up for 9 months after treatment. After 12 months, there were 62 evaluable patients in the continuous group and 59 evaluable patients in the pulse group. The clinical response (i.e. the size of the affected area and the progress of the infection) and mycological cure (i.e. negative results on microscopy and culture) were the main outcome measures. A clinical response was defined as a cure or a marked improvement. Clinical response rates were 69%, in the continuous group, and 81% in the pulse group at month 12; the corresponding mycological cure rates were 66 and 69%. A better improvement in signs and symptoms was noted in the pulse group. Six patients were withdrawn from treatment because of adverse events, not all of which were thought to be drug-related. There were no clinically relevant laboratory abnormalities. We conclude that both regimens are effective, safe and well tolerated. The superiority of one treatment over the other was not established, but the results tended to favour pulse therapy. Equivalence testing confirmed that pulse therapy was at least equivalent to continuous treatment.
