Diverse patterns of anti-TNF- α-induced lupus: case series and review of the literature

We describe three patients with ATIL. The first patient had a classical drug-induced lupus (DIL) presented by thrombocytopenia that resolved after infliximab discontinuation. The second case experienced symmetric polyarthritis of 14 joints in rheumatoid arthritis (RA)-like distribution accompanied by l ymphopenia. The third one had a severe serositis including ascites and pleural and pericardial effusions along with pancytopenia. In this patient, ATIL coexisted with anti-TNF-α-induced hepatitis. The second and third patients met the American College of Rheumatology classification criteria for SLE . Nevertheless, all three cases exhibited ANA and anti-dsDNA positivity, and only the second patient had anticardiolipin (aCL IgG) and anti-histone antibodies. The coexistence of both lupus-like syndrome and hepatitis following anti-TNF-α therapy in the same patient is very rare, and to the best of our knowledge, only four such case reports are mentioned in literature. Patients with mild ATIL may tolerate another anti-TNF-α agent without recurrence of the disease. Rheumatologists should be aware of the distinct clinical presentations of ATIL and its coexistence with other rare anti-TNF-alpha complications such as hepatitis.
