Detailed Description
Until now, there is no well-established evidence based option to treat CL caused by the Leishmania tropica, besides antimonial injections. Alternative treatment options are not available in Pakistan, or there is limited evidence of the effectivity.
Effectiveness of thermotherapy in L. tropica is studied in only three studies in OWCL with a variable cure rate (54.1% - 98%). But it could be an attractive option, because only one treatment session is required and studies report less scarring tissue. Another promising treatment option is oral miltefosine. There is considerable evidence in the literature of the efficacy of miltefosine in treatment of CL caused by L. major, however no studies have been conducted to evaluate the efficacy in CL caused by L. tropica species. This oral treatment could have major benefits for CL patients as it can be provided in peripheral health facilities and to patients who have contraindications to antimony treatment (elderly, and patients with cardiac or renal disease, or diabetes). A combination of thermotherapy and miltefosine, the advantages offered by this combination are that a) the use of a topical plus a systemic treatment would hypothetically have an additive effect of two treatments with different modes of action. For the reason that systemic treatment could eliminate those circulating or remaining parasites located in the periphery of the lesion that topical treatment fails to remove, which might be the cause of a relapse, b) it may reduce the necessary length of treatment with miltefosine. For these above reasons, in a prospective trial we aim to evaluate the effectiveness and safety of thermotherapy, miltefosine and the combination of thermotherapy and miltefosine in CL caused by L. tropica, with the objective to find a treatment with an efficacy which is non-inferior to the standard of care with antimony injections.

- lesion size ≥0.5 cm and ≤4 cm
- not located on the ear, nose, near to the eye or mucosal membranes, on joints, or on a location that in the opinion of the principle investigator (PI) is difficult to apply thermotherapy (TT) or intralesional (IL) injections
