Treatment of rheumatoid arthritis with levamisole: long-term results and immune changes. 1979

L A Runge, and R S Pinals, and R H Tomar

We treated 29 rheumatoid arthritis patients with levamisole. on the basis of a 25% improvement in any 3 of 6 measurements 95% of the patients had a favourable response within 20 weeks. However, 64% of the patients discontinued levamisole by 40 to 60 weeks because of rash or secondary treatment failures. Delayed skin reactivity to streptokinase-streptodornase increased significantly in the entire treatment group, but there was in inverse correlation between skin test enhancement and clinical response. There was no overall change in lymphocytes response to phytohaemagglutinin (PHA) after 4 and 16 weeks of treatment, but seven patients with enhanced lymphocyte responsiveness to PHA experienced an earlier clinical response to levamisole. Treatment with levamisole frequently results in clinical improvement in rheumatoid arthritis, but this is not clearly related to a stimulatory effect on cell-mediated immunity. Its long-term usefulness may be limited by a high incidence of relapse and rash.

D007978 Levamisole An antihelminthic drug that has been tried experimentally in rheumatic disorders where it apparently restores the immune response by increasing macrophage chemotaxis and T-lymphocyte function. Paradoxically, this immune enhancement appears to be beneficial in rheumatoid arthritis where dermatitis, leukopenia, and thrombocytopenia, and nausea and vomiting have been reported as side effects.

D008213 Lymphocyte Activation Morphologic alteration of small B LYMPHOCYTES or T LYMPHOCYTES in culture into large blast-like cells able to synthesize DNA and RNA and to divide mitotically. It is induced by INTERLEUKINS; MITOGENS such as PHYTOHEMAGGLUTININS, and by specific ANTIGENS. It may also occur in vivo as in GRAFT REJECTION.

D002986 Clinical Trials as Topic Works about pre-planned studies of the safety, efficacy, or optimum dosage schedule (if appropriate) of one or more diagnostic, therapeutic, or prophylactic drugs, devices, or techniques selected according to predetermined criteria of eligibility and observed for predefined evidence of favorable and unfavorable effects. This concept includes clinical trials conducted both in the U.S. and in other countries. Clinical Trial as Topic

D001172 Arthritis, Rheumatoid A chronic systemic disease, primarily of the joints, marked by inflammatory changes in the synovial membranes and articular structures, widespread fibrinoid degeneration of the collagen fibers in mesenchymal tissues, and by atrophy and rarefaction of bony structures. Etiology is unknown, but autoimmune mechanisms have been implicated. Rheumatoid Arthritis
