Dear KP,
Everytime I have these patients I wonder if I can have something better. Indeed, now miltefosine shows to be better and safer.
Also, you could try the heat machine, that sounds pretty good, as suggested by John and Abhay.
So, if you could get, use them. If not, go to the standard treatment with SbV, as prescribed. Young people are more resistant to side effects.
Best regards,
Carlos.

I am writing to ask for your help with information and suggestion about treating cutaneous leishmaniasis in Panama.

 

I have only very sketchy information about the case as follows:

 

1.	An American young man has 2 skin lesions, one of which is on the abdomen. 
2.	He was diagnosed to have cutaneous leishmaniasis
3.	A course of 30-day intra-muscular injection of pentavalent antimony is prescribed.

 

I wonder about the intramuscular instead of intra-lesion antimony treatment and also the duration of the treatment for 30 days ?

 

Looking forward to hearing from you at your earliest convenience.

 

KP

Hi Gena,

 

Thanks a lot for your offer. 

 

Our purpose is to work together with John and Abhay, who I know personally for a long time. May be the experience here will lead to broader application.

 

I am forwarding your email to DNDi to see if they could help us in getting the machine into the country, since they have expertise in this kind of humanitarian treatment.

 

My best regards,

 

Carlos.

This is good to try.

 

KP

Dear Dr. Costas,

Thermosurgery is committed to the research and treatment of leishmaniasis.  We are pleased to work with you and assist your patients.  We can lend you an instrument to use in your program.  Our biggest hurdle is getting the equipment into the country.  If you work with an NGO or government agency that can assist us in the importation that would be helpful.  

Lets discuss the logistics to see if it is feasible to get you the equipment.  I would suggest that you work with Dr David and Dr Satoskar on the recommended treatment protocol.  

We would want to receive documentation regarding the use of the equipment and a paper so that we can educate others on the value of this treatment.  

 

Warm regards,

gena

	KP, do you have any idea about prices? Please send me the brand name to see if I can easily import them. Best wishes to Jean, Carlos

	Carlos will undoubtedly go with those, which are clinically acceptable and feasible for the sake of expediency. 

	 

	In a separate message, the causative agent was said to have been identified as L amazonensis. Thermosensitivity of this species has been well-documented, suggestive of thermotherapy. There is already the suggestion of hot bath. One-use heat pad/heat wrap available over-the-counter in the USA drug stores is just as innocuous to consider as some topical ointments suggested.

	Dear friends,

	 

	This is really a such touching and motivated community, and leish-l is proving to be an excellent tool for solving the leishmaniasis toughest problems throughout the world. The word "together" sounds really powerful in such a cases.

	 

	What os showing up from these kind emails is a face of science coming not only from the bench, the hospitals, the field, but a science coming straight from the heart.

	 

	Let me summarize some of the lessons and suggestions. Please correct me if I skip some.

	 

	1) Hot bath - Teresina is very hot, and hot showers are rare here. However, we can easily provide her an electric shower. Should it be a tube? How long the bath would last?

	 

	2) BCG - one or two shots.  We will do it. Any hint about the intervals between the shots?

	 

	3) Previous drug therapy: ImunoglucanTM (cell wall of Saccharomyces cerevisiae), and saquinavir, after her delivery (Intracellular survival of Leishmania species that cause visceral leishmaniasis is significantly reduced by HIV-1 protease inhibitors. <http://www.ncbi.nlm.nih.gov/pubmed/18816190> ).

	 

	4) Besides miltefosine we got a good hint where to find it (Paladino, Canada), which has excellent temporary effect (Zerpa et al, 2006), we should consider: 

	a) lower/corrected doses of paramomycin (Bryceson) - we have also to find the drug outside Brazil, since it is not distributed/approved here; 

	b) gamma-interferon (who produces/sells it?).

	c) fluconazol/itraconazol/(voriconazol?).

	d) amiodarone - in vitro testing does not sounds so good.

	e) topic imiquimod  (IxiumTM cream) - apparently easy to find. concentration of 5%?

	f) photodynamic therapy - with Dr. Dagoberto Silveira, we are investigating where to do it around.

	g) immunotherapy with suicide photo-inactivated Leishmania (KP Chang).

	 

	Please check what really seems reasonable. My feeling is that most of the suggestions can be tried.

	 

	My warmest regards,

	 

	Carlos.

	Anthony,
	
	
	because there are only a few options left, would you consider at one point low dose pentamidine (3 mg/kg every week or so, as you did in DCL patinets in Ethiopia in the 70s if I remember)? Could be used either to stabilize the situation before starting on a coadministration, or as a maintenance after the co-administration, in both cases with careful monitoring of kidney function ?

		Dear Carlos
		As you are well aware DCL is very difficult to treat. The big problem is that the defect in specific CMI is more profound than that in VL and may never recover, in contrast with the defect in VL which bounces back quickly.
		
		To have any chance of curing the patient, treatment  should be monitored by quantitative slit skin smears (as for splenic aspirates in VL) from multiple pre-selected sites, every week or two weeks, and treatment continued until negativity and for some weeks or months longer.  When slit skin smears become negative, hunt for any nodular or infiltrated lesions and take deep biopsies and look for amastigotes there. Keep on hunting and smearing. Sometimes, at the end of all this, evidence of CMI may appear, and cure becomes a possibility. I am sure that the method of treating is more important than the choice of drug - so long of course that the parasite is susceptible to the drug.
		
		Hannah Akuffo has sent you the abstract relating to 3 patients treated by Sabawork Teklemariam in Addis Abeba. That article details this approach.
		
		Do you know the species of Leishmania causing Maria's DCL, and its sensitivities? In Addis Abeba parasites were cultured from two of the patients and sensitivities determined and isobolograms drawn to look for synergy. The isolates were sensitive to paromomycin and sodium stibogluconate was synergistic. It would be worth while to make cultures before you start any new treatment and have the isolate tested in this way. I expect that you have a lab that could do this; if not, Simon Croft might be able to advise.
		
		Miltefosine has been very successful in a number of situations in South American CL and showed promise for DCL,  but patients relapsed despite prolonged treatment.
		1. Zerpa O, Ulrich M, Blanco B, et al. Diffuse cutaneous leishmaniasis responds to miltefosine but then relapses. Br J Dermatol. 2007;156:1328-1335.
		
		In a few patients with VL-HIV confection whom I treated in London, miltefosine worked well at first, but the patients relpased while still on treatment and drug resistance was supected but not tested. Miltefosine has a pharmacokinetic profile with a long tail that might make it susceptible to the devlopment of resistance, especially if the therapeutic window for a given isolate was narrow. So you might want to think about adding a second drug to go with miltefosine from the beginning. I am not sure what might be the best drug for combination; perhaps Josh Berman might have an opinion. It is of course essential to ensure contraception.
		
		You could also consider the combination of paromomycin and low dose SSG. In view of Maria's poor renal function you might need to modify the dose of paromomycin and to monitor function.
		
		Robert Vinson is CEO of Paladin Labs, and would I am sure help you locate miltefosine. <rvinson at paladin-labs.com>
		
		Richard Chin is CEO of One World Health,  and would, I am equally sure, help you locate paromomycin, should you consider that path.  http://www.oneworldhealth.org/contact-us  Phone: +1 415-421-4700 Fax: +1 415-421-4747
		
		I wish you and Maria all the best in this venture.
		Anthony
		
		
		Dear Jennie
		Immunotherapy proved rather disappointing in VL. It seems that the patient needs a decent immune response in the first place to benefit from immuno-boosting.
		Sadly

		Dear all,
		
		Maria Cleudimar has cutaneous diffuse leishmaniasis due to Leishmania amazonensis. She used to be a long time patient form Dr. Jackson Costa, in the countryside of Maranhão State, Brazil, since she was 10 years old, after a disease that started when she was just five. Now, she is under my and Dorcas care, at the age of 30, living in the city of Teresina.
		
		Her long time DCL does not respond to the treatment antimonium anymore. Although we still prescribe liposomal amphotericin B at very low dose (3mg/kg/once a week), her situation is deteriorating progressively, her renal function does not allow any additional dosing since creatinine is presently above 3mg/dL, and previous biopsy had shown tubular damage apparently secondary to the drug, without evidence of amyloidosis. We tried several combinations of different drugs, without success. Her situation worsened a lot during her recent pregnancy (the baby is eight months old now).
		
		Our hope now stands only in miltefosine, for oral chronic use, but the drug is not licensed or available in Brazil yet (to my knowledge).
		
		With her permission I attached some of her pictures, hoping to sensitize critical people in order to help me to get miltefosine and the permission for prescription in Brazil (or any other oral drug with promising efficacy, and without nephrotoxicity, if known). Moreover, we need to know about the dose adjustment for the renal impairment, and how long the drug could safely be used.
		
		One picture shows her face before treatment, and another after the pregnancy, with the baby. One shows the situation of her thighs, another the calf of the leg and the last one the infiltration of the palate.
		
		Hoping a little from friends, my kindest regards,
		
		Carlos.
		
		PS. Please understand that the pictures are allowed not for publication or public presentation. Cleudimar permission is restricted to this forum.
