The efficacy of topical adipose mesenchymal stem cell-conditioned medium versus framycetin gauze dressing in chronic plantar ulcer of leprosy: A randomized controlled trial.

Background Wound healing shows a unique interaction of several cells, growth factors and cytokines. The healing of chronic plantar ulcer of leprosy is influenced by various factors, one of which is the concentration of growth factors and cytokines related to the pathogenesis of impaired wound healing. Growth factors and cytokines can be found in the secretome of adipose mesenchymal stem cells. Aim To compare the effectiveness of topical adipose mesenchymal stem cell-conditioned medium and framycetin gauze dressing only on the healing of chronic plantar ulcer of leprosy. Methods In this randomised controlled trial, 32 patients with chronic plantar ulcer of leprosy were recruited. After detailed clinical and initial debridement, patients were randomised to two groups to receive either topical adipose mesenchymal stem cell-conditioned medium (n = 16) or framycetin gauze dressing only (n = 16) applied every three days for up to eight weeks, following which the ulcer size, adverse reactions and complications if any were monitored weekly. Results Healing percentage increased each week in all groups. Statistical differences between groups (P < 0.05) were observed from week 2 onwards for ulcer mean size reduction and from week 3 onwards for ulcer mean depth reduction. There were no adverse reactions or complications. Limitations Off-loading on subjects were not performed. Conclusion Adipose mesenchymal stem cell-conditioned medium is a potential therapeutic agent in the management of chronic plantar ulcer of leprosy.

Tratamento da úlcera plantar devido à hanseníase / Treatment of leprosy-induced plantar ulcers

Introdução: A úlcera plantar por hanseníase é uma lesão no pé resultante da falta de sensibilidade plantar. O objetivo é descrever o tratamento realizado em portadores de úlceras plantares por hanseníase. Métodos: Estudo de prontuários de portadores de úlcera plantar atendidos no Hospital Sarah em Brasília, de 2006 a 2016, quanto ao sexo, idade, etiologia, localização e tratamento. Resultados: Foram atendidos 27 pacientes, 17(62,96%) homens e 10 (37,04%) mulheres, procedentes de Goiás e DF, na faixa etária de 41 a 60 anos (40,74%). Todos necessitaram de um ou mais procedimentos cirúrgicos. Conclusão: Observou-se maior frequência no sexo masculino, grau avançado, localizadas no primeiro artelho. Todos necessitaram de procedimentos cirúrgicos e não cirúrgicos, evoluindo com cicatrização completa da ferida, amputação transtibial em um caso e de artelhos em sete casos, e 90% dos casos apresentaram recorrência da úlcera após um ano.

Introduction: Leprosy-induced plantar ulcers result from a lack of plantar sensitivity. Objective: This study aimed to describe the treatment provided to patients with leprosy-induced plantar ulcers. Methods: We retrospectively reviewed the medical records of patients with plantar ulcers treated at Sarah Hospital in Brasilia from 2006 to 2016 and collected information about sex, age, etiology, location, and treatment. Results: A total of 27 patients (17 [62.96%] men, 10 [37.04%] women; 40.74% were aged 41­60 years) were treated from Goiás and the Federal District. All required ≥1 surgical procedure. Conclusion: A higher frequency of advanced grade was observed in men, primarily on the first toe. All needed surgical and non-surgical procedures and achieved complete wound healing. Transtibial amputation was required in 1 case and toe amputation in 7 cases; 90% patients developed ulcer recurrence after 1 year.

Prospective analytical study of assessment of off loading by Total Contact Cast in treatment of non healing plantar ulcers in anaesthetic foot.

BACKGROUND: Chronic planter ulcer, also known as trophic ulcer, shows no tendency towards healing. It is usually seen in sensory deficient foot. The clinical result of a sensory, motor or autonomic loss of a nerve function is frequently the same--ulceration, although the exact cause may vary. The treatment principle involves dressing and avoiding pressure on the ulcerated site called 'offloading' and patient education for prevention. AIM OF THE STUDY: To determine the outcome of non-healing planter ulcers in an anaesthetic foot treated with offloading, total contact casting (TCC), in terms of rate and duration of healing and percentage of ulcers healed based on improvement of Wagner's grading with respect to the clinical profile of the patient. METHOD: Detailed examination of the patients was done, and neuropathic foot confirmed. Surgical debridement of the ulcer was done to take off all the necrotic tissues, periwound callus, and infected material down to viable tissues. Once the ulcer became clean, a total contact cast was applied with a walking iron for ambulation. TCC was renewed every 2 weeks and rate of healing was assessed. RESULT: 80% of the cases healed within 8 weeks, healing defined by complete re-epithelisation of wound. Average duration of healing of an ulcer was 6.73 ±1.92 weeks. LIMITATIONS OF THE STUDY: Small sample size and the lack of control subjects for comparison. CONCLUSION: Offloading with total contact casts is believed to be the gold standard method with better and faster healing rates.

Why person affected by leprosy did not look after their plantar ulcer? Experience from Pakokku zone, Myanmar.

A cross-sectional study was carried out to identify methods of caring plantar ulcers in leprosy patients and the underlying causes of poor plantar ulcer care during January and February 2008. This was conducted in Pakokku zone as it was one of the "9 selected townships of the Disabilities survey, i.e., Basic Health Staff project 2003/4", which was funded by Japan International Cooperation Agency. After getting consent, all available leprosy cases, i.e., 101 cases with foot disability grade 2 were interviewed with the pre-tested questionnaire. Among 101 cases, 13 cases who took care of their ulcer poorly and 20 who did none of the recommended measures were recruited for in-depth interview (IDI). The subjects were largely old people, males and people with no marriage partner. The majority had earned money by doing sedentary job. Prolongation of ulcers was observed in 78 cases. Most had been suffering from ulcers for years. When asking face-to-face interview, all the recommended care measures were not reported. Among these recommended measures, a large number of respondents reported about soaking measure. However, these reported measures were contradicted to the preventive methods which they disclosed in IDI. Plantar ulcer care seemed to be an individualised practice. The individual ways of performing were related to their view of ulcer, the environment, and occupation, and custom, communication with family and health staff. The findings identified the actual practice of plantar ulcer care in study areas. It is suggested that the current performance of planar ulcer care is inadequate and more attention should be given to achieve the target set by the programme as a recommendation.

Government health workers as implementers of prevention of disability measures: an assessment of a prevention of disability project in selected counties of Guizhou Province, Peoples' Republic of China.

OBJECTIVE: The purpose of this study was to assess the effectiveness of government health workers as agents for the prevention of disability. DESIGN: A prevention of disability (POD) project for people affected by leprosy was conducted in nine counties of Guizhou Province, Peoples' Republic of China. The project was implemented by government health workers. In accordance with the principles and national criteria of the National Centre for Leprosy Control (NCLC) POD Pilot programme, 1215 people affected by leprosy were selected, followed up and assessed with the use of impairment summary forms through which essential indicators were routinely collected. RESULTS: Most improvements of disabilities occurred in the 1st year of the POD project. Fifty five people with neuritis were detected and treated with prednisolone out of 262 new patients; 47 of these improved; 1130 people completed a 3-year self-care programme; 88.5% of red eyes, 83.9% of hand ulcers and 62.8% of simple foot ulcer cases healed during that period. One hundred and ninety six people who presented with complicated ulcers were treated; of these 73 (37.2%) people presented with feet free of ulcers at the end of the project period. CONCLUSION: The POD project was a cost-effective method of preventing further disability occurrence among people affected by leprosy. Government health workers were generally able to implement and monitor the project effectively. Most of people affected by leprosy were satisfied that the improvements in their disabilities had been due to self-care. The programme had helped them to increase their confidence to implement self-care activities.

[Improved care of foot ulcer using foot pressure measurement and foot care method sheet].

At this sanatorium, the number of foot bottom ulcer patients was 13 and the tenure of the foot bottom ulcer was average 11 years. According to the treatment that was not unified, we thought about the cause of the prolongation. Therefore, we made evaluation and care method sheet ("foot care sheet") of the ulcer for the unification. We used the foot pressure measurement system (F-scan) to 4 patients for the pressure dispersion of the ulcer. We devised the protection law of the ulcer, and an ulcer did not require pressure more than 5 kilos/cm2. We recorded the size of the ulcer, weight of the liquid from ulcer, a photograph to care sheet once a week. I performed ulcer protection law and management with the foot care sheet to 4 patients for average 4 months. As a result, the ulcers of 3 patients out of 4 patients became small.

[Background of development and effectiveness of myanmar sandals (the activity of Leprosy Control and Basic Health Services Project in Myanmar)].

"Leprosy control and Basic health service Project" was terminated at March 2005 within the scope of the period. I was assigned to develop the Plantar protect footwear for neuropathic feet, which called "Myanmar Sandals" in common. These sandals are not made by new technologies but made by basic knowledge. I would like to report about this activity as which is a part of distinguished strategy of ODA (Official Development Assistance) for developing country, but not as the technical report of these sandals. There is only one National Leprosy Hospital in Myanmar. At the time this project started, there were only two footwear technicians for the people who had disabilities by after effect of Hansen's disease in this country. And, it would appear that the number of the people is over 50,000. Furthermore, the budget of national hospital is not enough to refill necessary consumable supplies and materials. Although, I should instruct new technique which like making in Japan in ordinary circumstances, I could not think that such technical transfer by using costly imported materials woud bring beneficial effect and be continued. We were bound to be anxious about such situations when we made the plan. As a result of examining a plan based on these situations, we reached the conclusion that development of the simplified ready-made footwear was pressing need.

Comprehensive treatment of complicated plantar ulcers in leprosy.

OBJECTIVE: To investigate feasible treatment methods for plantar ulcers in leprosy patients according to the agreement between the Ministry of Health (MOH) of China and the Leprosy Mission International (LMI). METHODS: A total of 2599 complicated foot ulcers in 1804 leprosy cases underwent surgic treatment. Plastic fixation and supports were used, dressings were changed regularly, and protective footwear and modified insoles were provided. RESULTS: Of the 2599 foot ulcers 1446 (55.64%) healed. The cure rate of the patients treated in leprosy hospitals was 71.31%, with 219 (15.15%) recurrences of foot ulcers. The recurrence rate of those who lived at home was 18.35%. CONCLUSIONS: Comprehensive treatment of foot ulcers has a high cure rate and a low recurrence rate. Reduction of workload, avoidance of long distance walking, intensification of education on foot self-care and provision of financial support are the main measures for preventing a recurrence of foot ulcers.

An intensive self care training programme reduces admissions for the treatment of plantar ulcers.

This paper describes, in detail, an intensive 14 day Self Care Training Programme that is conducted at Lalgadh Leprosy Services Centre in Nepal. An evaluation of the programme was undertaken in which hospital admission for infected plantar ulceration was the outcome measure. It was found that those who had undertaken the programme were less likely to have been admitted for hospital treatment in a 3-month follow-up period (chi 2 = 5.1, P = 0.02). An odds ratio of 1:1.8 (95% CI = 0.15-0.01) was also calculated. This paper presents an overview of the issues related to impairment, a description of the Self Care Training Programme, an analysis of the evaluation results and a discussion of the findings.

Final report about Stage II Collaboration Project on Leprosy Rehabilitation.

OBJECTIVE: To undertake the pilot experiments of prevention of disability (POD) in 14 different geographical areas to serve as examples for future development of rehabilitation work in China and in Asia. METHODS: According to the principles and national criterion, 27 000 people affected by leprosy were selected and assessed using disability record forms at beginning and followed up regularly for observing changes of different indicators. RESULTS: A total of 197 neuritis cases were detected and treated with prednisolone out of 1 407 new or active cases. Self-care training of eyes, hands and feet were conducted for 10 500 disabled people affected by leprosy. Comprehensive therapy was given to 1 804 cases having complicated ulcers of which 1 055 cases have got their ulcers healed. Out of 706 prostheses, 613 were given to patients with satisfactory results. Surgical treatment was given to 269 cases and 251 have shown good progress. CONCLUSION: Most of patients have got benefit from the project in function or appearance which is very helpful for their going back to the society and agreed by foreign experts during the final evaluation. The experiences from the project can be implemented in the whole country.

Management of simple plantar ulcers by home based self-care.

Seeking a solution to bring down the prevalence of simple plantar ulcers in the field, Damien Foundation India Trust (DFIT), Chennai, developed a curriculum to teach the field staff of all its projects. The purpose was to make patients self-reliant in the care of their plantar ulcers in their homes. The strategy used was to make patients take care of their ulcers using tools found in their homes and surroundings and become responsible for the care of their limbs. This strategy was implemented in eight projects of DFIT and the programme was followed regularly for one year. Regular monitoring and evaluation showed that under this strategy the prevalence of plantar ulcers was reduced by about 50%.

[How does one treat the osteitis and osteoarthritis of the extremities in older leprosy patients using granulated table sugar?]. / Comment guérir les ostéites et ostéo-arthrites des extrémités des anciens malades de la lèpre par le sucre cristallisé alimentaire?

A common problem of osteitis and septic arthritis is the recurrent bone infection after surgical debridement, a problem frequently encountered in patients with sequela leprosy. In these cases the authors propose the use of an ancient method of post surgical wound care based on the treatment with ordinary granulated sugar. The hyperosmolar climate created this way in the wounds inhibits the bacterial growth, enhances bacterial death and therefore permits the growth of granulation tissue in order to recover the debrided nude bones. At ILAD (Leprosy Institute of Dakar), 36 osteitis and septic arthritis were treated and healed during the last 2 years from March 1995 to March 1997 using this technic. All the wounds healed in the mean-time of 44 days. Only two of them needed a second debridement and healed afterwards. Up to now the method using ordinary sugar was applied in the treatment of infected wounds, eschars and postsurgical infections. Our experience shows that it also can be indicated to treat bone infections. This method is easy to apply also under often difficult field conditions and is very cheap.

[Nature and sensitivity of bacteria superinfecting plantar ulcers caused by leprosy at the Marchoux Institute, Bamako, Mali]. / Nature et sensibilité des bactéries surinfectant les maux perforants plantaires d'origine lépreuse à l'Institut Marchoux, Bamako, Mali.

To determine potential usefulness of antimicrobial agents and to guide their prescription in the treatment of leprosy plantar ulcers, we conducted an in vitro study about germs' nature and sensitivity to antibiotics. We took samples of plantar ulcers secretion from 107 patients at Marchoux Institute. 92.5% of those ulcers were infected. These samples revealed 145 strains of micro-organisms among those, Staphylococcus aureus (70 strains) and genus Pseudomonas (41 strains) were the most frequent. These bacteria were resistant to several antibiotics currently used at Marchoux Institute (tetracycline, penicillin, cotrimoxazol and erythromicin). Antibiotics, efficient at 80% on tested strains, were expensive for patients. They cannot be recommended for the treatment of local infections. These results outline that the main treatment in plantar ulcers is based upon antiseptic solutions and keeping feet at rest. Antibiotherapy in case of extension of local infection would be based on the results of a previous study of sensitivity.

Exposure to pulsed magnetic fields in the treatment of plantar ulcers in leprosy patients--a pilot, randomized, double-blind, controlled clinical trial.

A pilot, randomized, double-blind, controlled clinical trial to study the effect of exposure to pulsed magnetic fields (PMF) on the rate of healing of plantar ulcers in leprosy patients was undertaken. Twenty patients were randomly allocated to receive standard wound-care treatment (controls) and 20 others received standard treatment plus exposure to PMF (sinusoidal form, 0.95 to 1.05 Hz, amplitude +/- 2400 nano Teslas) (study group) for four weeks. Assessment of the outcome of treatment was based on the volume of ulcers, calculated from the maximal length, breadth and depth of the ulcer recorded on the day of admission, at one and two weeks and at the end of treatment. The analysis of the results was based on 15 control patients and 18 PMF patients after deletion of four patients due to irregularity in attendance and three others on account of suspected malignancy of the ulcers. In the control group, the geometric mean volumes of the ulcers were 2843 and 1478 cu mm on the day of admission and at the end of the treatment (P = 0.03); the corresponding values in the PMF group were 2428 and 337 cu mm, respectively (P < 0.001). A decrease in the volume of 40% or more was observed in 53% of control patients and 89% of PMF patients (P = 0.02); a decrease of 80% or more was observed in none of the controls and in 33% of PMF patients. These findings strongly suggest that exposure to PMF causes a significantly more rapid healing of plantar ulcers in leprosy patients.

[Simplification and codification of treatment for leprous plantar ulcers]. / Simplification et codification des soins aux maux perforants plantaires lépreux.

Practically leprous plantar ulcers (PU) are difficult to treat and heal under field condition. Considering the important number of patients showing a PU, the directors of national leprosy control programmes are determined, within the programmes on prevention of disabilities (POD), to treat the PU in the field. Therefore it appears to be essential to codify and simplify their treatment thus enabling it to be effective. The healing of PU being the only criteria of effectiveness of the technique. Four clinical stages were defined, each corresponding to a precise way of treatment using only essential and basic products at low cost. During the trainings about the treatment techniques and attitudes much emphasize is given on the discharge of the PU, on the trimming of the wound and on the products to use according to PU's evolutionary stage.
