Efficacia e utilità del monitoraggio terapeutico di autoanticorpi e farmaci inibitori del Tumor Necrosis Factor alpha in pazienti in trattamento per patologie autoimmuni
Therapeutic monitoring of autoantibodies Tumor Necrosis Factor α inhibitor drugs: efficacy and benefit for patients with autoimmune diseases
<p>Therapeutic monitoring of autoantibodies Tumor Necrosis Factor &alpha; inhibitor drugs: efficacy and benefit for patients with autoimmune diseases. Tumor necrosis factor alpha (TNF&alpha;) is a proinflammatory cytokine involved in the pathogenesis of chronic inflammatory disease, such as rheumatoid arthritis, psoriatic arthritis, ankylosing spondylitis, Chron&rsquo;s disease and ulcerative colitis. TNF&alpha; inhibitors (anti-TNF&alpha;) are monoclonal antibodies drugs directed against TNF&alpha; (i.e. adalimumab, infliximab, etarnecept, golimumab and certolizumab). Their effect consists in reducing the inflammatory response of autoimmune diseases. Several randomized controlled trials and observational studies evaluated the therapeutic efficacy of these drugs and reported a clear benefit for patients affected by chronic inflammatory disease treated with anti-TNF&alpha;, but also a high risk of reactions and infections in the injection site. These drugs are immunogenic, and consequent anti-drug antibodies (ADA) formation may decrease the functional drug concentration resulting in a loss of response. Therefore, we evaluated the impact of ADA on therapeutic response through meta-analyses, showing that detectable ADA significantly reduced TNF&alpha; inhibitors response. ADA could interfere with drugs and compromise their effects, so the determination of serum ADA levels could improve the patient&rsquo;s management. Even if the decrease of therapeutic response, due to ADA production, is well documented, the clinical benefit of serum ADA determination remains unclear. At the moment, there are many indications about the use of immunogenicity test to guide the therapy, but more information should be acquired before implementing this test in clinical practice.</p>

Interferenze da farmaci biologici: un caso di accumulo di Bevacizumab
Interference by biological anti-cancer drugs: the case of Bevacizumab
<p>We report a case of interference with electrophoretic (CZE) and immunofixation (IFE) techniques after repeated cycles of a biological anti-cancer drug. A man, with colon neoplasia, underwent a prolonged therapy with Bevacizumab and other chemoterapeutic agents from September 2013 until May 2015. Before therapy, the electrophoretic pattern was normal while, during treatment, it showed a modification suggestive of the presence of a monoclonal component (MC) that was possible to type (IgG <span style="font-family:symbol; font-size:11.0pt">k</span>) and to quantify (8 g/L) after 22 cycles of therapy. The cooperation with clinicians and our study about biological drugs, allowed us to recognize this MC as an interference due to the accumulation of Bevacizumab in the serum of the patient. The laboratory report of a MC would have involved the patient in further procedures that are invasive, cost and time expensive. This case emphasizes the importance of a strict collaboration between physicians and the clinical laboratory in the management of patients treated with biological drugs.</p>
