Sulphasalazine has been shown to have an effect in patients with spondyloarthropathies, but the clinical indication for its use is controversial and its long term effect has not yet been evaluated. Treatment with sulphasalazine was analysed retrospectively in a group of 372 patients with a wide range of spondyloarthropathies to determine subsets of patients showing differential effects of the drug. One hundred and one patients received sulphasalazine at a mean daily dose of 2 g (ankylosing spondylitis, 54 patients; psoriatic arthritis, 21 patients; reactive arthritis, four patients; arthritis related to inflammatory bowel disease, six patients; undifferentiated spondyloarthropathy, 16 patients). A comparison between treated and untreated patients suggests that only patients with active and severe disease were treated whatever the precise diagnosis or the amount of axial disease in the spondyloarthropathy. After six months of treatment improvement was noted in 59 patients unrelated to their subgroup or amount of axial disease. After a mean follow up of 20 months, 37 patients were still receiving treatment, 33 had discontinued the drug because of inefficacy, 14 because of side effects, six because of remission of the disease, and 11 for other reasons. Comparison between the beginning and end of treatment showed a statistically significant decrease in morning stiffness, erythrocyte sedimentation rate, and daily dose of non-steroidal anti-inflammatory drugs (NSAIDs). It is concluded that: (a) a low percentage of patients with spondyloarthropathy have active disease requiring treatment with sulphasalazine despite the use of NSAIDs (27% in this study); (b) in this subgroup of patients sulphasalazine seems to be of clinically relevant benefit in 59%; and (c) this benefit does not seem to be correlated with either the precise diagnosis of spondyloarthropathy or the amount of axial disease.

In a 12-month double-blind placebo-controlled trial, the effect of sulphasalazine was studied in 40 patients with ankylosing spondylitis. The treatment group showed significant improvement in pain, stiffness, sleep disturbance (p less than 0.05), finger/floor distance, erythrocyte sedimentation rate, C-reactive protein, orosomucoid and IgA levels (p less than 0.01). There was improvement in sleep disturbance (p less than 0.05), finger/floor distance and erythrocyte sedimentation rate (p less than 0.01) in the placebo group. Sulphasalazine did not retard radiological progression as measured either by plain X-ray or computerised tomographic scans. Multiple analysis of variance did not show a significant difference in disease activity indicators between the 2 groups.

Sulphasalazine has recently been shown to have an effect in ankylosing spondylitis but the clinical indication for its use is controversial. We have used an 'interventional' study design to investigate the clinical and laboratory effects of sulphasalazine in a group of 20 patients with active ankylosing spondylitis and peripheral joint disease. Following an initial assessment period, patients were treated with sulphasalazine for 24 weeks and the drug was then withdrawn and the patients monitored for a further 12 weeks. Significant improvements were observed in chest expansion, number of active joints, ESR and CRP which deteriorated after withdrawal of sulphasalazine. No change in spinal mobility was demonstrated. The 'interventional' design may be a useful screening procedure for identifying potential second line drugs in ankylosing spondylitis.

Sulphasalazine was administered to 48 patients with reactive synovitis (RS) and ankylosing spondylitis (AS) with peripheral arthritis, resistant to nonsteroidal anti-inflammatory drugs. Thirty-seven patients underwent an ileocolonoscopy and in 33 patients signs of chronic or active inflammation of the ileum and/or ileocecal valve were found. Forty-two patients improved after 3 to 12 months of treatment; 50 per cent of them went into remission. In most of the patients improvement failed to occur in the first 2 months of treatment. There was no recurrent disease activity in patients responding to the treatment. Adverse reactions were rare and did not necessitate interruption of treatment. The beneficial effect of sulphasalazine in the treatment of RS and AS with peripheral arthritis needs to be confirmed in double-blind controlled studies.

Sulphasalazine has been reported to be effective in ankylosing spondylitis with peripheral arthritis, but its efficacy in spondylitis is unknown. Thus 60 patients with active ankylosing spondylitis without peripheral arthritis or gastrointestinal symptoms were randomly allocated to one of two therapeutic groups. One group received 2 g sulphasalazine daily for six months and the other a placebo. Thirteen patients (six given placebo and seven given sulphasalazine) dropped out of the trial and were considered to be treatment failures. After six months' follow up efficacy was rated as good or very good by 15 of the 30 patients given sulphasalazine and by only six of the 30 given placebo (p less than 0.02). Furthermore, in the patients given sulphasalazine the daily consumption of non-steroidal anti-inflammatory drugs, functional index, and plasma IgG concentrations had fallen significantly. These data suggest that sulphasalazine may be a safe and effective treatment for spondylitis in ankylosing spondylitis.

Sulphasalazine (salicyl-azo-sulphapyridine) has been in clinical use for over 40 years. Although the drug was originally introduced for the treatment of 'rheumatic polyarthritis' and ulcerative colitis, it is only in the past 10 years that its value in rheumatology has been appreciated. Controlled studies indicate that the drug is an effective remittive agent in both rheumatoid arthritis and ankylosing spondylitis. This is an area of great research interest since the drug is proving to be a useful tool for investigating the aeteology and pathogenesis of these diseases.

IgM, IgG and IgA class serum antibodies against the whole Klebsiella pneumoniae, Escherichia coli and Proteus mirabilis bacteria, as well as against K. pneumoniae and E. coli lipopolysaccharides (LPSs) were studied earlier in two separate patient populations of 99 and 85 patients with ankylosing spondylitis (AS) and in 102 healthy blood donors by enzyme immunoassay. In this study the patients were divided into groups according to the presence or absence of peripheral arthritis. The patients with peripheral type AS had increased levels of IgM and IgA class antibodies against K. pneumoniae, whereas the patients with axial type AS had increased levels of IgG and IgA class antibodies to K. pneumoniae, as well as IgA class antibodies against E. coli and P. mirabilis bacteria. Sulphasalazine treatment decreased the IgM and IgA class antibodies in peripheral AS and IgA class antibodies in axial AS against K. pneumoniae LPS. The antibody levels were also decreased against E. coli and P. mirabilis bacteria in the sera of patients with axial AS. The immunological findings in patients with peripheral and axial form of AS were different from each other and thus may reflect different aetiopathogenetic mechanisms for these two types of AS.

Gut inflammation plays a crucial role in the pathogenesis of spondylarthropathies (SpA) since ileocolonoscopic studies have demonstrated the presence of gut inflammation in different forms of this concept: in ankylosing spondylitis (AS) (60%), in enterogenic (90%) and urogenital reactive arthritis (20%), in undifferentiated SpA (65%), in the pauciarticular and axial forms of psoriatic arthritis (16%), in late onset pauciarticular juvenile chronic arthritis (80%) and in acute anterior uveitis (66%). The strong relationship between gut and joint inflammation was demonstrated by performing a second ileocolonoscopy: remission of the joint inflammation was always connected with a disappearance of gut inflammation, whereas persistence of locomotor inflammation was mostly associated with the persistence of gut inflammation. During further evolution 20% of the non-ankylosing spondylitis SpA patients can develop AS. About 6% of the total group SpA patients, in whom inflammatory bowel disease (IBD) was excluded, developed Crohn's disease 5 to 9 years later. All these patients initially presented with gut inflammation, which indicates that this finding has prognostic value. The high prevalence of evolution to IBD in SpA patients confirms the thesis that both disease entities bear common pathogenic mechanisms, and confirms the place of IBD in the concept of SPA. Sulphasalazine (SASP), a successful drug in the treatment of IBD, has demonstrated its effectiveness in the treatment of SpA. The beneficial effect of the drug in this disease entity could be due to its anti-inflammatory effect on the gut wall, by normalizing its permeability and by preventing the entrance of antigens through the defective gut wall. However, SASP could not prevent the evolution to IBD.

The joint disorders taxonomically included in the group of seronegative spondyloarthropathies under the generic name of enteropathic arthropathy represent the most frequent extra-intestinal manifestation of inflammatory bowel disease (IBD), affecting 33% of patients. Their frequency is similar to that of ulcerative colitis and Crohn's disease. Enteropathic arthropathy consists of two main joint alterations, peripheral and axial arthritis, as well as a variable group of other peri-articular disorders. Type 1, or pauciarticular, peripheral arthritis generally coincides with IBD exacerbations, while type 2, or polyarticular, peripheral arthritis follows an independent course from IBD. Axial involvement precedes and follows an independent course from IBD and can behave as ankylosing spondylitis or asymptomatic sacroiliitis. The treatment of these rheumatologic disorders is based on the application of general measures and the use of nonsteroidal anti-inflammatory agents; intraarticular corticosteroid administration may eventually become necessary. Sulphasalazine and/or infliximab, which are indicated when the previously mentioned measures fail, can be used to treat both the articular and intestinal diseases simultaneously.

The main objectives of medical therapy in ankylosing spondylitis (AS) are to relieve pain, stiffness and fatigue and to prevent structural damage. The Assessment in Ankylosing Spondylitis Working Group has proposed different domains with specific instruments to assess the efficacy of therapeutic agents classified as symptom-modifying and disease-controlling antirheumatic drugs. Non-steroidal antiinflammatory drugs (NSAIDs) are still the first-line treatment in the management of AS, and they are effective in controlling symptoms such as pain and stiffness and maintaining mobility in many patients. A recent randomized trial suggested that the progression of radiological damage occurs less on continuous use of celecoxib compared with on-demand use. If such findings were confirmed by other studies, the therapeutic value of NSAIDs in AS may extend beyond symptom control. However, for each individual patient, the expected advantages of treatment with NSAIDs should be weighted against any possible gastrointestinal and cardiovascular disadvantages. Disease-modifying antirheumatic drugs (DMARDs) are widely used for second-line therapy in AS, but the evidence for their efficacy is poor. The term 'DMARD' has been borrowed from rheumatoid arthritis, and none of the DMARDs have been shown to prevent or significantly decrease the rate of progression of structural damage which is required to be qualified as a disease-controlling antirheumatic drug for AS. Sulphasalazine is the most extensively studied DMARD and studies suggest some degree of clinical benefit confined to peripheral joint involvement, but no evidence of benefit in axial disease. Methotrexate, which is the gold standard DMARD in rheumatoid arthritis, does not seem to have a substantial therapeutic effect in AS on axial or peripheral joint involvement. Leflunomide appears to exert little beneficial effect, if any, even on peripheral joint involvement. There is also good evidence that local therapy with corticosteroids is effective and may be used in selected patients. Oral corticosteroids may be somewhat effective in relieving the symptoms of AS, but this has not been formally studied. Small studies have reported favourable results with intravenous methylprednisolone pulse therapy, but the effect is temporary. Pamidronate and thalidomide have been used in some preliminary trials but need further studies to assess their potential role in treating AS patients resistant or intolerant to other forms of treatment. Treatment with tumour necrosis factor blockers is not discussed in this review.
