Drug-induced hepatitis and lupus during infliximab treatment for psoriasis: case report and literature review.

BACKGROUND

Infliximab (IFX) can induce elevation of hepatic aminotransferase levels. Hepatitis has been reported in patients treated with IFX and with risk factors such as viral hepatitis, alcohol intake, or concomitant use of hepatotoxic drugs. Liver disorders occurring in a patient without risk factors have rarely been reported, and liver biopsies to substantiate the liver changes have very rarely been described. The presence of lupus-like symptoms with newly positive antinuclear antibodies (ANAs), sometimes with double-stranded deoxyribonucleic acid (DNA) antibodies, has also been reported with IFX. Only a few articles have reported in detail these types of adverse events in patients with psoriasis. To our knowledge, the combination of lupus-like symptoms with simultaneous occurrence of a biopsy-proven hepatitis has not been reported with the use of IFX for psoriasis.

OBJECTIVE

Description of a case of drug-induced hepatitis in a patient with concurrent clinical and serologic features of lupus induced by IFX.

METHODS

We present the case of a 40-year-old woman with psoriasis who developed a biopsy-proven drug-induced hepatitis and concurrent lupus symptoms with positive ANAs while under IFX treatment. A review of related publications is presented.

CONCLUSION

The clinician must be aware of uncommon side effects of IFX, such as liver anomalies and development of autoantibodies. Liver enzymes should be monitored regularly, and ANAs should be checked if liver enzymes are increasing and in the presence of lupus symptoms.
