Abstract

Background: Treatment of arthritis is carried out using corticosteroids, methotrexate, sulfasalazine-like agents, and TNF-α-blocking agents such as infliximab and adalimumab. The disadvantages of these agents are high-cost, severe side effects including leucopenia, and in some cases the necessity of administration by injection. Polyvalent immunoglobulin formulations derived from bovine colostrum and marketed as a standardized formulation for oral application, are reported to be efficacious in chronic pain syndromes but are rarely, if ever, used as an alternative medication in such patients.
Aims: To treat arthritis in a real-world setting using polyvalent immunoglobulins in 2 patients, in one case where no alternative treatment modality was available and in another patient in whom the use of polyvalent immunoglobulins appeared to be a suitable option.
Materials and methods: Two male subjects aged 46 and 82 years with confirmed diagnosis but not well-controlled arthritis/polyarthritis receiving either high-dose NSAIDS, corticosteroids, methotrexate injections, with previous use of, or recommendations for treatment with monoclonal antibodies (etanercept and adalimumab) were treated with oral polyvalent immunoglobulins (KMP01; dose range 10 – 20 g daily) in real-world settings, in one case during a field excursion in Peru.
Results: The treatment produced a rapid alleviation of pain in both patients, in one patient where the symptoms were severe and debilitating. In the second patient methotrexate SC injections could be discontinued, and there was a progressive reversal of leucopenia (leucocyte count 3.9 × 10³/µL) over a period of ~ 3 months. Discussion: Polyvalent immunoglobulins have been shown previously to reduce the expression of interleukin-6 and C-reactive protein in peripheral blood monocytes, events attributed to the neutralization of gut-derived endotoxin ligands lipopolysaccharides (LPS) driving the basal immune response. The mode of action of KMP01 on cytokine expression is therefore similar to the TNF-α-blocking agents etanercept and adalimumab.
Conclusion: Findings from two case reports support the rationale for using polyvalent immunoglobulins as an effective and safe alternative in arthritis patients receiving standard treatments, in particular, methotrexate and TNF-α-blocking agents.
