Abstract


BACKGROUND:

To date, Kaposi sarcoma has not been mentioned among the adverse effects of triptolide/tripdiolide, ethyl acetate extracts or polyglycosides of the Chinese herbal remedy Tripterygium wilfordii Hook F.

CASE REPORT:

A patient was diagnosed with rheumatoid arthritis at the age of 29 years. She underwent treatment with corticosteroids, methotrexate and gold sodium thiosulfate, and was chronically taking ketoprofen. At the age of 59 years she started to take a powder (≈2 g/day) from a Chinese physician for treatment of rheumatoid arthritis. This powder was supplied to her regularly for 10 years. At the age of 69 years, multiple soft, violaceous to dark-red patches, plaques, nodules and blisters of varying sizes appeared on a background of severely edematous skin on her legs, and later on her arms. Biopsy specimens of the leg lesions were diagnostic for human herpesvirus 8-associated Kaposi sarcoma. Triptolide (235 µg/1 g) and tripdiolide were found in the Chinese powder by the use of Liquid Chromatography Electrospray Ionization Mass Spectrometry. Administration of the powder was stopped and medication with paclitaxel was introduced. General condition of the patient improved and skin lesions diminished significantly.

CONCLUSIONS:

This case indicates a possible association between triptolide/tripdiolide chronic intake and development of human herpesvirus 8-associated Kaposi sarcoma. Triptolide/tripdiolide could contribute to development of Kaposi sarcoma by reactivation of latent human herpesvirus 8, permitted by immunosuppression induced by triptolide.

Abstract


Key Words: Secondary cancers, Rheumatoid arthritis, Methotrexate, Vinorelbine, Kaposi's sarcoma

For a number of years we have been following the medical literature to find a relationship between chronic treatment with methotrexate and breast cancer occurrence, because we had had in our clinic a female patient who had had two consecutive cancers following methotrexate treatment for rheumatoid arthritis (RA). We were much surprised to find in some papers that breast cancer incidence is low in women with RA. Since then, we have found several papers explaining the low incidence of breast cancer among women being under NSAIDs, but those papers are not univocal. Methotrexate is a known antifolate agent and it has been demonstrated that dietary shortage of folate is a risk factor for breast cancer development.
