Trial Details

What is the research question being addressed?

Is thermotherapy by the hand-held Exothermic Crystallization (HECT) device equally safe and effective when compared to thermotherapy by the ThermoMed device (localized radiofrequency induced heat device), in the treatment of cutaneous leishmaniasis showing poor response to intralesional sodium stibogluconate?

Intervention(s) planned

Study setting: Skin clinics of selected hospitals in Sri Lanka.

Method of allocation: Patients who are enrolled to the study will be allocated to two arms using block randomization with a computer generated random number series with block sizes 4 and 6.

Arm 1 will receive Thermotherapy by hand-held Exothermic Crystallization (HECT), one application daily at 51oC for 3 minutes duration given for 7 consecutive days.

Arm 2 will receive Thermotherapy by ThermoMed device, as a single application at 50oC for a duration of 30 seconds.

Inclusion criteria

  1. Age more than 12 years and less than 65 years
  2. Parasitologically confirmed CL lesion
  3. Undergone at least 10 intralesional injections of sodium stibogluconate
  4. Form of lesion: localized nodules, papules, ulcerating nodules, ulcers or plaques and the number of lesions: one.
  5. Longest diameter of the lesion less than 5cm

Exclusion criteria

  1. Any known chronic or concomitant illness such as hypertension, diabetes, heart disease, chronic renal or liver disease as determined by the investigators.
  2. Pregnancy
  3. Breastfeeding
  4. Immuno-compromised status including HIV co-infection and patients on immune-suppressants.
  5. Patients with more than one CL lesion
  6. Lesions which are on the nose or cartilaginous part of the ear or very close to the eyes and lips or which are situated lesser than 2cm away from a mucous membrane.
  7. Incapability of participant or the guarding to comply with the protocol as judged by the investigator.
  8. Anticipated unavailability for follow up visits
  9. Persons on pacemakers or having any implanted metallic devices
  10. Lesions which are infected

Primary outcome(s)

1.

Proportion of initial cure rate in each treatment arm (defined as: Reduction of lesion size at least by 50% of the pre-treatment size)

 [

Day 90 from the commencement of the interventions

]

Secondary outcome(s)

1.

  1. Presence or absence of adverse effects in each treatment group. (i) Pain (using Wong-Baker visual analogue scale) (ii) Blisters, scarring and secondary infection (clinical observation)

  2. Proportion of lesions (papules/nodules/plaques) with 100% reduction in size compared with the pre-treatment size at each measurement time point (at each follow up visit)

  3. Proportion of patients with 100% reduction in size compared with the pre-treatment size of the ulcerated lesions over time

  4. Proportion who has achieved final cure (no lesional relapse by day 180)

 [

Outcomes 1-3: At follow up visits on day 14,30,60,90,180 from the commencement of the intervention

Outcome 4: At the follow-up visit on day 180 from the commencement of the intervention
