Since cellular and humoral immune mechanisms were shown to be involved in the pathogenesis of rheumatic diseases, efforts have been made to influence these systems therapeutically. Aside from suppression of the immune response, studies have been conducted to evaluate to what extent immunostimulation might be of value in the treatment of rheumatic diseases. Levamisole, chemically a simple synthetic agent recently shown to have immunorestorative capacities in anergic cancer patients, has been administered in several rheumatic diseases. The drug was administered either continuously or intermittently in a daily dose of 150 mg over several months. In about half of the rheumatoid arthritis patients a significant improvement was noted. Beneficial effects and sometimes even dramatic improvement lere observed in some patients with systemic lupus erythematosus, ankylosing spondylitis and Reiter's syndrome. Levamisole did not alter the course of psoriatic arthritis. Significant adverse reactions were leukopenia and allergic skin reactions. Other side effects were mild and did not require interruption of drug intake. The use of levamisole in rheumatic diseases is still experimental, but with accumulating experience it may provide a true improvement in control of rheumatic diseases.

In 12 patients with ankylosing spondylitis with involvement of the peripheral joints and high activity of the disease process, cyclophosphamide was given in intravenous doses of 200 mg every second day for 3 weeks, followed by oral doses of 100 mg once weekly for 3 months to a total dose of 3 300 mg. Before this treatment and after 18-24 months the following clinical parameters were determined: spinal mobility, degree of intensity of spinal and articular pains, and the number of involved joints. After the treatment an evident clinical improvement was observed, with decreased values of the laboratory indices of the disease activity. Apart moderate erythrocyturia in one case and transient leukopenia in another case, no other side effects were observed. The improvement in cases with coexistent amyloidosis was relatively small.

The long-term tolerability and efficacy of indomethacin were evaluated in a retrospective study of 67 patients with moderate to severe rheumatoid arthritis, osteoarthritis, or ankylosing spondylitis who took the drug daily for periods ranging from three to 20 years. Only patients who had not experienced side effects during the first ten to 14 days of indomethacin therapy were included. No other anti-inflammatory agents were taken along with indomethacin. The average daily dosage ranged from 50 to 150 mg; for 81% of patients, the average daily dosage was 75 to 100 mg. Only nine (13%) of the 67 patients experienced side effects, all of which were transient and mild. Three patients had headache, five patients had gastrointestinal symptoms, and one patient had both gastrointestinal symptoms and headache. Repeated urinalyses did not reveal any significant abnormalities. There were no instances of leukopenia. A comparison of clinical and laboratory assessments at the initial and latest office visits indicated that signs of active inflammation had been well controlled by daily indomethacin therapy. Erythrocyte sedimentation rates were generally lower and hemoglobin values tended to be higher at the latest visit. Clinically, patients appeared to have benefited from the long-term administration of indomethacin with respect to both tolerability and efficacy.

A clinical evaluation of phenylbutazone and Butapyrin(R) (a mixture of phenylbutazone and aminopyrine) was made in 409 patients who had a variety of rheumatic diseases. Preliminary European claims were substantiated.In gout a specific favorable effect was brought about by phenylbutazone alone. Effects equivalent to the previously reported favorable response to Butapyrin (Irgapyrin) were observed when its constituent phenylbutazone was used alone. The drug had a suppressive effect in a high percentage of patients with rheumatoid arthritis, ankylosing spondylitis, arthritis with psoriasis and mixed arthritis (rheumatoid arthritis plus osteoarthritis). Favorable effect in peritendinitis of the shoulders, osteoporosis of the spine and acute lumbosacral strain also was noted. Toxicity resulted in discontinuance of medication in 10 per cent of patients with each drug. Manifestations of toxicity generally included fluid retention, nausea and rash, but there were several instances of transitory leukopenia and anemia. There was one instance of agranulocytosis with Butapyrin but none with phenylbutazone.dagger Aggravation of peptic ulcer occurred in ten patients with hemorrhage in two. Generally the toxicity was of a low order as compared with that of other drugs having an antirheumatic effect.

A 50-year-old man with ankylosing spondylitis who developed neutropenia after treatment of etanercept, with two positive rechallenges, and after the first infliximab infusion, is described. Although leukopenia and neutropenia related to etanercept and infliximab have been described as rare adverse events from clinical trials data, their mechanism of action are unknown. This patient developed recurrent mild neutropenia after exposition of two different antitumor necrosis factors; therefore, it seems to be an adverse reaction related to the therapeutic group. Doctors should be aware of this potentially severe adverse effect in patients treated with antitumor necrosis factor.

Renal amyloidosis is a complication of ankylosing spondylitis. A possible pathogenetic role is due to TNF-alpha, with a direct action on glomerular receptors TNFR2 and renal injury, secondary to deposition of amyloid fibrils. The most frequent clinical manifestation is proteinuria or nephrotic syndrome. Etanercept, a soluble receptor of TNF-alpha, binds this circulant cytokine with a progressive improvement of renal function and reduction of deposits of amyloid. Transient leukopenia, observed during ankylosing spondylitis, should not be considered a controindication to the use of Etanercept, but it requires a constant monitoring. The benefit observed in our patient can represent an indication to the use of Etanercept for the management of amyloidosis.

Recurrent macrophage activation syndrome (MAS) is very rare. We present the case of an adolescent boy with human leukocyte antigen (HLA) B27-positive ankylosing spondylitis (AS), who experienced episodes of recurrent MAS since he was a toddler. A 16-year-old boy was admitted because of remittent fever with pancytopenia and splenomegaly after surgical intervention for an intractable perianal abscess. He had been diagnosed with hemophagocytic lymphohistiocytosis (HLH) 4 different times, which was well controlled with intravenous immunoglobulin and steroids since the age of 3. We were unable to identify the cause for the HLH. He remained symptom-free until the development of back pain and right ankle joint pain with swelling at 15 years of age. He was diagnosed with HLA B27-positive AS with bilateral active sacroiliitis. He showed symptom aggravation despite taking naproxen and methotrexate, and the symptoms improved with etanercept. On admission, his laboratory data showed leukopenia with high ferritin and triglyceride levels. Bone marrow biopsy examination showed histiocytic hyperplasia with hemophagocytosis. There was no evidence of infection. He received naproxen alone, and his symptoms and laboratory data improved without any other immunomodulatory medications. Genetic study revealed no primary HLH or inflammasome abnormalities. In this case, underlying autoimmune disease should have been considered as the cause of recurrent MAS in the young patient once primary HLH was excluded.
