showed that the shortened regimen was efficacious in relapse cases, but was inferior to the standard regimen for new cases of the disease. Nifurtimox-eflornithine combination treatment (NECT) is an effective regimen for the treatment of second stage gambiense African trypanosomiasis. Trypanosome resistance After its introduction to the market in the 1980s, eflornithine has replaced melarsoprol as the first line medication against Human African trypanosomiasis (HAT) due to its reduced toxicity to the host. Trypanosoma brucei resistant to eflornithine was reported as early as the mid-1980s. The gene TbAAT6, conserved in the genome of Trypanosomes, is believed to be responsible for the transmembrane transporter that brings eflornithine into the cell. The loss of this gene due to specific mutations causes resistance to eflornithine in several trypanosomes. If eflornithine is prescribed to a patient with Human African trypanosomiasis caused by a trypanosome that contains a mutated or ineffective TbAAT6 gene, then the medication will be ineffective against the disease. Resistance to eflornithine has increased the use of melarsoprol despite its toxicity, which has been linked to the deaths of 5% of recipient HAT patients. Excess facial hair in women The topical cream is indicated for treatment of facial hirsutism in women. It is the only topical prescription treatment that slows the growth of facial hair. It is applied in a thin layer twice daily, a minimum of eight hours between applications. In clinical studies with Vaniqa, 81% percent of women showed clinical improvement after twelve months of treatment. Positive results were seen after eight weeks. However, discontinuation of the cream caused regrowth of hair back to baseline levels within 8 weeks. Vaniqa treatment significantly reduces the psychological burden of facial hirsutism. Chemo preventative therapy It has been noted that ornithine decarboxylase (ODC) exhibits high activity in tumor cells, promoting cell growth and division, while absence of ODC activity leads to depletion of putrescine, causing impairment of RNA and DNA synthesis. Typically, drugs that inhibit cell growth are considered candidates for cancer therapy, so eflornithine was naturally believed to have potential utility as an anti-cancer agent. By inhibiting ODC, eflornithine inhibits cell growth and division of both cancerous and noncancerous cells. However, several clinical trials demonstrated minor results. It was found that inhibition of ODC by eflornithine does not kill proliferating cells, making eflornithine ineffective as a chemotherapeutic agent. The inhibition of the formation of polyamines by ODC activity can be ameliorated by
