  1. MYCETOMA INTERNATIONAL CONFERENCE Monterrey, Mexico 24th-26th. May 2007 Elsheikh Mahgoub Faculty of Medicine ,University of Khartoum,Sudan.

  2. THERAPY OF MYCETOMA

  3. Mycetoma is a chronic, localised slowly progressive disease, involving cutaneous, subcutaneous tissue and ultimately bone.

  4. It is characterised by tumefaction, destructive granuloma, deformity and discharging sinuses with intercommunicating channels which exude pus with granules of varying colour and size

  5. It is 52 years since Professor Gonzalez –Ochoa from your country published his work on the treatment of mycetoma due to Nocardia brasiliensis with Diamino-diphenyl sulphone(DDS)and 41 years since the publication of Professor Pedro Lavalle.

  6. We published on successful treatment of mycetoma caused by Actinomadura madurae, A.pelletierii, Streptomyces somaliensis and Nocardia brasiliensiswith Sulphamethoxazole plus Trimethoprim35 years ago.

  7. Later on in 1976 we published on the treatment of 144 cases of actinomycetoma using COMBINATION THERAPY of Streptomycin and cotrimoxazole or streptomycin and DDS.

  8. In 1984, together, with Professor Samia Gumaa, we reported on the first successful treatment of Eumycetoma due to Madurellamycetomatisby ketoconazole

  9. Oliverio Welch and his colleagues 20 years ago, in 1987, reported on the use of Amikacin alone and in combination with Trimethoprim-sulphamethoxazole in the treatment of actinomycetoma caused by N.brasiliensis.

  10. Ahmed Fahal had a trial with Itraconazole to treat patients with eumycetoma caused by Madurella mycetomatis (Data not yet published).

  11. At present a trial is going on at the Mycetoma Centre in Khartoum where patients with mycetomata due to A.madurae,Apelletierii and S.somaliensis are being treated with amikacin. Preliminary results are impressive

  12. TOPICAL APPROACH Elfadil got his MD in 2004 by working on the seeds of a Sudanese herb (Lipdiumsativum)growing along the White Nile.The seeds of this plant are ground and emulsified in yogurt and applied daily as a dressing to the mycetoma even if the lesion is closed.

  14. The latest report is that of Bonifaz et al February 2007 who reported on successful treatment of Actinomycetoma due to Nocardia spp. withAmoxyclav 875/125

  15. In a recent electronic article on Mycetoma in eMedicine, January 2007,Basillioet al have narrated all drugs used in medical treatment of mycetoma,their dosage,mode of action and side effects.

  16. Oliverio Welch and Salinas-Carmona in February 2007 in the same web site published a comprehensive article updating treatment of both actinomycetoma and eumycetoma.

  17. We are conducting an experiment to test in vitro Sensitivity of 15 strains of M. mycetomatis against Fluconazole, Itraconazole, Ketoconazole and Voriconazole.

  18. Ketoconazole

  19. Itraconazole

  20. M.Mycetomatis against Voriconazole

  21. Our results show that Ketoconazoleis still themost potent followed byvoriconazole, Itraconazoleand least byFlucconazole.

  22. With this array of drugs what approach or strategy should we advise for Therapy or treatment of MYCETMA??

  23. Questions to be answered first: • Site of mycetoma? (Is SurgeryPossible) • Actinomycetoma or Eumycetoma?(Drugs Different) • Any Previous mycetoma treatment? (Try Different Drug) • Any previous surgery? (Recurrence) • What drug cost can he/she afford? (For Sustaining Trt)

  24. Actinomycetoma All agents of actinomycetoma start with Streptomycin 1 gram per day intramuscular. plus 2 tablets cotrimoxazole twice daily for one month.Do not disturb successful treatment. If treatment fails shift to Amikacin.

  25. After Treatment S.Somaliensis Mycetoma pedis Before Treatment with Streptomycin cotrimoxazole.

  26. Trt.Amikacin /Cotrimoxazole Before treatment After Treatment

  27. Treatment If No Response, shift to Streptomycin Dapsone[Beware toxic effects to Bone marrow Anaemia Leucopenia. Supplement trt with Fe and Folic acid.]

  28. Treatment If no response, start Amoxycillin/clavulanic acid.

  29. Trt. EUMYCETOMA Ketoconazole 200 mg b.d. for 3 weeks. If response is minimal try Voriconazole6mg/kg iv infused over 2 hrs and then Itraconazole. [ Check Liver Function Tests before and monthly during trt.]
