Cost-effectiveness of a fixed combination of hydroquinone/tretinoin/fluocinolone cream compared with hydroquinone alone in the treatment of melasma.

BACKGROUND: A once-daily fixed combination of hydroquinone, tretinoin, and fluocinolone acetonide (Tri-luma) is a newly available treatment for melasma. OBJECTIVE: To assess cost-effectiveness of triple combination therapy (TCT) applied once daily and hydroquinone alone applied twice daily in the U.S., Argentina, Brazil, Chile, and Colombia from a payer's perspective. METHODS: Clinical data and utilization of key health resources (medication only) were assessed within an 8-week clinical trial conducted in Brazil. Total cost per primary success (complete clearing) was used to compare each treatment with not treating and incremental cost effectiveness ratios were used to compare between treatments. RESULTS AND CONCLUSION: TCT had a 30% better rate of complete clearing than hydroquinone with a lower cost in the U.S. and an incremental cost in other countries. In every country, cost per primary success was lower for TCT than for hydroquinone. Results were robust to varying assumptions of success rates and quantity used.

Use of all-trans retinoic acid to treat acute promyelocytic leukemia: a case with very severe features at the onset in Nicaragua.

We observed a child with acute promyelocytic leukemia (APL) who, at the onset, had extremely severe hemorrhagic and septic complications. According to our experience in Nicaragua, there was a very high risk of early death. The patient was successfully treated with a program that included all-trans retinoic acid (ATRA) followed by cytotoxic chemotherapy. ATRA has two important features: it is effective in initial treatment of APL and it is inexpensive. Because of the high cost and the need for extensive supportive care, optimal myeloablative therapy used in patients with various types of acute myeloid leukemia generally cannot be given in developing countries. ATRA treatment for APL is affordable everywhere.
