Severe adalimumab-induced thrombocytopenia in a patient with Crohn's disease

Abstract: Crohn's disease is a chronic transmural inflammatory disorder characterized by inflammation of the intestine. Anti-TNF-α drugs are used for induction and maintenance of remission in patients with this condition. Thrombocytopenia is an uncommon side effect of treatment with anti-TNF-α drugs. We report the case of a 71-year-old woman diagnosed with Crohn's disease who developed severe adalimumab-induced thrombocytopenia and who did not respond to standard therapy for thrombocytopenia.

“…Isolated thrombocytopenia following the use of anti‐TNF drugs has been reported. There are multiple hypotheses as to the possible aetiology, including autoimmune platelet destruction secondary to antiplatelet antibodies, immune complexes triggering the complement cascade, another unknown autoimmune mechanism, or idiosyncratic reaction …”

“…Thrombocytopenia has been reported to be prolonged after cessation of therapy. In severe cases this could persist for up to 6 months and also preclude exposure to any further anti‐TNF agents . This is likely to be a class effect and rechallenge with same class could be risky and therefore discouraged .…”

“…The first hypothesis is that anti-TNFα drugs can stimulate the production of antibodies, targeting hematologic cells by inducing the apoptosis of Th1 lymphocytes. Immune-mediated thrombocytopenia and neutropenia during treatment with anti-TNFα drugs, including adalimumab, have been reported (3,4). Although the mechanisms associated with anti-TNFα-induced thrombocytopenia and neutropenia are unclear, a hypothesis suggested that anti-TNFα drugs induce the apoptosis of Th1 lymphocytes and consequently leave a relative excess of Th2 lymphocytes.…”

“…Our previous experience does not indicate thrombocytopenia on the paleolithic ketogenic diet. However, low thrombocyte number is a well-known side effect of the use of adalimumab in Crohn's disease [14,15]. It is also noteworthy that a return to the strictest form of the paleolithic ketogenic diet resulted in an increase in thrombocyte number.…”
