Self-care treatment for lymphoedema of lymphatic filariasis using integrative medicine.

BACKGROUND: Lymphatic filariasis (LF) is a neglected tropical disease presenting mainly as lymphoedema (elephantiasis). At present, LF is not effectively treated. Integrative medicine (IM) treatment for lymphoedema uses a combination of Indian traditional medicine, Ayurveda, alongside yoga exercises, compression therapy, antibiotics and antifungal treatments, providing a useful combination where resources are limited and different practices are in use. OBJECTIVES: To assess the effectiveness of the IM in the existing clinical practice of lower-limb lymphoedema management and to determine whether the treatment outcomes align with the World Health Organization (WHO) global goal of LF management. METHODS: Institutional data from electronic medical records of all 1698 patients with LF between 2010 and 2019 were retrospectively analysed using pre- and post-treatment comparisons and the National Institute for Health and Care Excellence guidelines for clinical audit. The primary treatment outcomes evaluated were limb volume, bacterial entry points (BEEPs), episodes of cellulitis, and health-related quality of life (HRQoL). Secondary outcomes included the influence of the patient's sex, duration of illness, education and employment status on volume reduction. Multiple regression analysis, t-test, χ2-test, analysis of variance, Mann-Whitney U-test and the Kruskal-Wallis test were used to assess the association between IM and patients' treatment outcomes. RESULTS: Limb volume reduced by 24.5% [95% confidence interval (CI) 22.47-26.61; n = 1660] following an intensive supervised care period (mean 14.84 days, n = 1660). Limb volume further reduced by 1.42% (95% CI 0.76-2.07; n = 1259) at the first follow-up visit (mean 81.45 days), and by 2.3% between the first and second follow-up visits (mean 231.32 days) (95% CI 1.26-3.34; n = 796). BEEPs were reduced upon follow-up; excoriations (78.4%) and intertrigo (26.7%) were reduced at discharge and further improvements was achieved at the follow-up visits. In total, 4% of patients exhibited new BEEPs at the first follow-up [eczema (3.9%), folliculitis (6.5%), excoriations (11.9%) and intertrigo (15.4%); 4 of 7 BEEPs were recorded]. HRQoL, measured using the disease-specific Lymphatic Filariasis Specific Quality of Life Questionnaire, showed an average score of 73.9 on admission, which increased by 17.8 at the first follow-up and 18.6 at the second follow-up. No patients developed new cellulitis episodes at the first follow-up, and only five patients (5.3%) developed new episodes of cellulitis at the second follow-up. CONCLUSIONS: IM for lower-limb lymphoedema successfully reduces limb volume and episodes of cellulitis, and also reduces BEEPs, leading to improved HRQoL. IM aligns with the LF treatment goals of the WHO and is a low-cost, predominantly self-care management protocol. IM has the potential to change care models and improve the lives of patients with lymphoedema.

Exploring determinants of hydrocele surgery coverage related to Lymphatic Filariasis in Nepal: An implementation research study.

BACKGROUND: Hydrocele is a chronic condition in males in which there is an excessive collection of straw-colored fluid, which leads to enlargement of the scrotum. It is a common manifestation of lymphatic filariasis (LF) affecting nearly 25 million men worldwide. Surgery is the recommended treatment for hydrocele and is available free of cost in all government hospitals in Nepal. This research explored patient, provider, and community factors related to accessing hydrocele surgery services by the patients. METHODS: This study employed a qualitative method. The research was conducted in two LF endemic districts, namely Kanchanpur and Dhading, which are reported to have the highest number of hydrocele cases during morbidity mapping conducted in 2016. In addition to five key informant interviews with the LF focal persons (one national and 4 district-level), nine in-depth interviews were conducted with hydrocele patients (5 of whom had undergone surgery and 4 who had not undergone surgery) and with 3 family members, and two focus group discussions with the female community health volunteers. RESULTS: Most of the respondents did not have knowledge of hydrocele as one of the clinical manifestations of LF nor that it is transmitted through a mosquito bite. Although perceived as treatable with surgery, most of the patients interviewed believed in as well as practiced home remedies. Meanwhile, fear of surgery, embarrassment, lack of money, along with no knowledge of the free hydrocele surgery acted as barriers for accessing the surgery. On the other hand, financial support, flexible guidelines enabling the hospital to conduct surgery, decentralization and scaling up of morbidity mapping along with free hydrocele surgery camps in any remaining endemic districts were identified as enablers for accessing surgery. CONCLUSION: Hydrocele surgery coverage could be improved if the program further addresses community awareness. There is a need for more focus on information dissemination about hydrocele and hydrocele surgery.

Community level morbidity control of lymphoedema using self care and integrative treatment in two lymphatic filariasis endemic districts of South India: a non randomized interventional study.

BACKGROUND: Currently there is no global program to manage lymphoedema as a result of lymphatic filariasis (LF). The primary aim of this study was to determine the efficacy of a previously proposed integrative treatment protocol, using locally available resources to address the morbidity, in a community village setting. METHODS: Two LF endemic districts of south India, Gulbarga in Karnataka (GK) and Alleppey in Kerala (AK), were selected for the study. All known patients were invited to an LF camp. Patients with grade two late or three lymphoedema were enrolled. All patients were given training in the integrative procedure which involved patient education and the domiciliary protocol. RESULTS: A total of 730 patients (851 limbs) completed the three and half month follow up. There was a statistically significant (1%) reduction up to mid thigh level volume measurement for both small (0.7-1.1 liters) and large (1.8-5.0 liters) limbs, p < 0.000. In AK inflammatory episodes at the three months interval reduced from 37.5% (127 patients) to 28.3% (96 patients) and in GK from 37.6% (147 patients) to 10.2% (40 patients), p < 0.000. All patients had reduced bacterial entry points. There was an overall improvement in quality of life in all domains of LF specific quality of life questionnaire p < 0.000. CONCLUSIONS: Self care and integrative treatment is possible in resource poor Indian village settings. Further work is needed to explore factors leading to better compliance by randomizing the interventions such as washing and emollient compression vs Ayurvedic and yoga interventions before integrative treatment is considered for national health programmes in developing countries.

Rapid community identification, pain and distress associated with lymphoedema and adenolymphangitis due to lymphatic filariasis in resource-limited communities of North-eastern Nigeria.

Identification of communities with people that could benefit from adenolymphangitis (ADL) and lymphoedema morbidity management within Lymphatic Filariasis Elimination Programmes (NLFEP) in many African countries is a major challenge to programme managers. Another challenge is advocating for proportionate allocation of funds to alleviating the suffering that afflicted people bear. In this study we developed a rapid qualitative technique of identifying communities where morbidity management programme could be situated and documenting the pain and distress that afflicted persons endure. Estimates given by health personnel and by community resource persons were compared with systematic household surveys for the number of persons with lymphoedema of the lower limb. Communities in Northeastern Nigeria, with the largest number of lymphoedema cases were selected and a study of local knowledge, physical, psychosocial burden and intervention-seeking activities associated with the disease documented using an array of techniques (including household surveys, key informant interviews, group discussions and informal conversations). Health personnel gave a more accurate estimate of the number of lymphoedema patients in their communities than either the community leader or the community directed ivermectin distributor (CDD). Community members with lymphoedema preferred to confide in health personnel from other communities. The people had a well developed local vocabulary for lymphoedema and are well aware of the indigenous transmission theories. Although the people associated the episodic ADL attacks with the rains which were more frequent at that period they did not associate the episodes with gross lymphoedema. There were diverse theories about lymphoedema causation with heredity, accidental stepping on charmed objects and organisms, breaking taboos. The most popular belief about causation, however, is witchcraft (60.9%). The episodic attacks are dreaded by the afflicted, since they are accompanied by severe pain (18%). The emotional trauma included rejection (27.5%) by family, friends and other community members to the extent that divorce and isolation are common. Holistic approach to lymphoedema morbidity management should necessarily be an integral component of the ongoing transmission elimination programme. Any transmission prevention effort that ignores the physical and psychological pain and distress that those already afflicted suffer is unethical and should not be promoted.

Bancroftian filariasis in the Kassena Nankana District of the upper east region of Ghana: a preliminary study.

A filariasis prevalence survey was conducted in April 1992 in the Southern sector of the Kassena Nankana District which was the site of the Ghana Vitamin A Supplementation morbidity trial. In all, 106 compounds from five different communities were randomly selected from the vitamin A trial database. All resident compound members of 10 years and above were clinically examined and blood was taken for thick films between 2100 and 0200 hours. Haemoglobin levels were also measured. All the blood slides were examined by the investigators in Navrongo. Two reference laboratories examined 10% each of the slides for quality control. In all, 531 people were examined, 247 males and 284 females. The results showed an overall microfilaraemia rate of 41.1% (95% CI 36.9-45.3%). The only species identified was Wuchereria bancrofti. The most important clinical manifestation was hydrocele, 30.8% of males (95% CI 25-36.6%); followed by elephantiasis of the leg, 3.6% of the study population (95% CI 2.0-5.2%). The mean haemoglobin level of the population was 12.4 g dl-1. There were no significant differences between the communities in clinical or parasitological findings.

The potential of mice as animal models for antifilarial screening.

Transplanted infections of Brugia pahangi and Dipetalonema viteae in male BALB/c and CDI mice were investigated as models for evaluating potential antifilarial compounds. The physiology and genetics of the above mouse strains are better defined than any of the rodent species currently used for primary in vivo screening, facilitating a more reproducible means for predicting the filaricidal activity of compounds. The recoveries of B. pahangi macrofilariae, implanted intraperitoneally were greater than or equal to 50% up to six weeks after implant in both CDI and BALB/c mice. The recoveries of D. viteae macrofilariae, implanted subcutaneously, were greater than 50% up to four weeks post implant but had fallen to less than 30% by six weeks. The survival of B. pahangi and D. viteae macrofilariae simultaneously implanted into mice mimicked that seen with the mono-infections, but significantly better recoveries were obtained from dual implanted CDI mice compared to the BALB/c mice when the numbers of macrofilariae implanted were varied. Standard antifilarials were evaluated against D. viteae and B. pahangi dual implanted into either CDI mice or gerbils. The mouse dual implant detected significant worm reductions against D. viteae, B. pahangi or both with all antifilarials tested except CGP 6140. Similarly under the test conditions CGP 6140 was not detected in the gerbil assay, but there were marked differences in the results obtained with the mice and gerbil models. The reasons for these differences are discussed.
