Abstract
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.

Abstract
Lymphatic filariasis (LF) is endemic in 72 countries; 15 million persons live with chronic filarial lymphedema. It can be a disabling condition, frequently painful, leading to reduced mobility, social exclusion, and depression. The Global Program to Eliminate Lymphatic Filariasis aims to stop new infections and care for affected persons, but morbidity management has been initiated in only 38 countries. We examine economic costs and benefits of alleviating chronic lymphedema and its effects through simple limb care. We use economic and epidemiological data from 12 Indian states in which 99% of Indians with filariasis reside. Using census data, we calculate the age distribution of filarial lymphedema and predict the burden of morbidity of infected persons. We estimate lifetime medical costs and lost earnings due to lymphedema and acute dermatolymphangioadenitis (ADLA) with and without community-based limb-care programs. Programs of community-based limb care in all Indian endemic areas would reduce costs of disability by 52%, saving a per person average of US$2,721, equivalent to 703 workdays. Per-person savings are 185 times the program's per-person cost. Chronic lymphedema and ADLA impose a substantial physical and economic burden in filariasis-endemic areas. Low-cost programs for lymphedema management based on limb washing and topical medication are effective in reducing the number of ADLA episodes and stopping progression of disabling lymphedema. With reduced disability, people can work longer hours per day, more days per year, and in more strenuous, higher paying jobs, resulting in important economic benefits to themselves, their families, and their communities.

Abstract
Introduction: Mass drug administration and morbidity management and disability prevention (MMDP) though considered as two pillars of global program for elimination of filariasis, implementation of MMDP was disregarded in several endemic countries. Limb hygiene is the main component of MMDP and to address its overall clinical benefits, a community-based study was undertaken in three sets of populations. Materials and Methods: After obtaining written informed consent, clinical, quality of life (QoL) assessments were carried out and lymphedema volume was measured for three groups of lymphedema patients at intake, at 6, and 12 months follow-up. Filarial lymphedema patients from three sets of villages categorized as "Previous VCRC MMDP," "State MMDP," and "Current VCRC MMDP" were considered for the study. Clinical examination and QoL assessment were carried out independently by a medical officer and a sociologist, respectively. Whoever available at the time of three field visits were registered and included in the study. In total, 67, 63, 66 and 75, 74 and 63 lymphedema (LE) patients completed clinical evaluation and QoL assessment from these groups, respectively. Results: Assessment of repeated measures of clinical parameters at baseline and two time points of follow-up by Friedman's test showed significant clinical improvements in skin color, texture, moisture, and ulcer (p > 0.05), in nails score and intertrigo score (p > 0.01). Assessed by Wilcoxon signed-rank test showed a significant reduction in the frequency Acute Dermato-Lymphangio-Adenitis episodes at 12 months follow-up in all the three MMDP groups (p < 0.001). However, the reduction of LE volume was significant (p = 0.009) only in the current Vector Control Research Centre (VCRC) MMDP group. There was no significant improvement in the QoL in all three groups. Conclusions: To achieve the desired clinical benefits by MMDP home care practices for the filarial lymphedema patients, regular monitoring by the auxiliary health workers is essential. National programs must consider monthly supervision through an integrated approach.

Abstract
BACKGROUND Lymphatic filariasis (LF) is endemic in 72 countries of Africa, Asia, Oceania, and the Americas. An estimated 25 million men live with the disabling effects of filarial hydrocele. Hydrocele can be corrected with surgery with few complications. For most men, hydrocelectomy reduces or corrects filarial hydrocele and permits them to resume regular activities of daily living and gainful employment. METHODOLOGY AND PRINCIPAL FINDINGS This study measures the economic loss due to filarial hydrocele and the benefits of hydrocelectomy and is based on pre- and post-operative surveys of patients in southern Malawi. We find the average number of days of work lost due to filarial hydrocele and daily earnings for men in rural Malawi. We calculate average annual lost earnings and find the present discounted value for all years from the time of surgery to the end of working life. We estimate the total costs of surgery. We compare the benefit of the work capacity restored to the costs of surgery to determine the benefit-cost ratio. For men younger than 65 years old, the average annual earnings loss attributed to hydrocele is US$126. The average discounted present value of lifetime earnings loss for those men is US$1684. The average budgetary cost of the hydrocelectomy is US$68. The ratio of the benefit of surgery to its costs is US$1684/US$68 or 24.8. Sensitivity analysis demonstrates that the results are robust to variations in cost of surgery and length of working life. CONCLUSION The lifetime benefits of hydrocelectomy-to the man, his family, and his community-far exceed the costs of repairing the hydrocele. Scaling up subsidies to hydrocelectomy campaigns should be a priority for governments and international aid organizations to prevent and alleviate disability and lost earnings that aggravate poverty among the many millions of men with filarial hydrocele.

Abstract
BACKGROUND Lymphedema is a condition of localized protein-rich swelling from damaged or malfunctioning lymphatics. Because the immune system is compromised, there is a high risk of infection. Infection in patients with lymphedema may present in a variety of ways. OBJECTIVE The goals of this review were to standardize the terminology of skin breakdown in the context of lymphedema, synthesize the available information to create best practice recommendations in support of the American Lymphedema Framework Project update to its Best Practices document, and create recommendations for further research. DATA SOURCES Publications on skin care and wounds were retrieved, summarized, and evaluated by a team of investigators and clinical experts. STUDY SELECTION AND DATA EXTRACTION Terms for lymphedema-associated skin breakdown were compiled and paired with photographs of commonly noted skin changes among patients with lymphedema. A list of standard dermatological terms was created. A more extensive literature search was then conducted by all authors. DATA SYNTHESIS Skin disorders associated with lymphedema have been classified into 5 categories. Descriptions, photographs, and recommendations for treatment are presented. CONCLUSIONS Skin care is an important defense against infection. Because of the lack of research, a consensus of thought and content leaders' opinion should guide the best practices for wound care in lymphedema.

Abstract
Lymphatic filariasis afflicts 68 million people in 73 countries, including 17 million persons living with chronic lymphedema. The Global Programme to Eliminate Lymphatic Filariasis aims to stop new infections and to provide care for persons already affected, but morbidity management programs have been initiated in only 24 endemic countries. We examine the economic costs and benefits of alleviating chronic lymphedema and its effects through a simple limb-care program. For Khurda District, Odisha State, India, we estimated lifetime medical costs and earnings losses due to chronic lymphedema and acute dermatolymphangioadenitis (ADLA) with and without a community-based limb-care program. The program would reduce economic costs of lymphedema and ADLA over 60 years by 55%. Savings of US$1,648 for each affected person in the workforce are equivalent to 1,258 days of labor. Per-person savings are more than 130 times the per-person cost of the program. Chronic lymphedema and ADLA impose a substantial physical and economic burden on the population in filariasis-endemic areas. Low-cost programs for lymphedema management based on limb washing and topical medication for infection are effective in reducing the number of ADLA episodes and stopping progression of disabling and disfiguring lymphedema. With reduced disability, people are able to work longer hours, more days per year, and in more strenuous, higher-paying jobs, resulting in an important economic benefit to themselves, their families, and their communities. Mitigating the severity of lymphedema and ADLA also reduces out-of-pocket medical expense.

Abstract
BACKGROUND Lymphedema is a debilitating and disfiguring sequela of an overwhelmed lymphatic system. The most common causes of secondary lymphedema are lymphatic filariasis (LF), a vector-borne, parasitic disease endemic in 73 tropical countries, and treatment for cancer in developed countries. Lymphedema is incurable and requires life-long care so identification of effective lymphedema management is imperative to improve quality of life, reduce the burden on family resources and benefit the local community. This review was conducted to evaluate the evidence for effective lymphedema self-care strategies that might be applicable to management of all types of secondary lymphedema. METHODOLOGY/PRINCIPAL FINDINGS Searches were conducted in Medline, CINAHL and Scopus databases in March 2015. Included studies reported before and after measures of lymphedema status or frequency of acute infections. The methodological quality was assessed using the appropriate Critical Appraisal Skills Program checklist. Descriptive synthesis and meta-analysis were used to evaluate effectiveness of the outcomes reported. Twenty-eight papers were included; two RCTs were found to have strong methodology, and overall 57% of studies were rated as methodologically weak. Evidence from filariasis-related lymphedema (FR-LE) studies indicated that hygiene-centred self-care reduced the frequency and duration of acute episodes by 54%, and in cancer-related lymphedema (CR-LE) home-based exercise including deep breathing delivered significant volume reductions over standard self-care alone. Intensity of training in self-care practices and frequency of monitoring improved outcomes. Cultural and economic factors and access to health care services influenced the type of intervention delivered and how outcomes were measured. CONCLUSIONS/SIGNIFICANCE There is evidence to support the adoption of remedial exercises in the management of FR-LE and for a greater emphasis on self-treatment practices for people with CR-LE. Empowerment of people with lymphedema to care for themselves with access to supportive professional assistance has the capacity to optimise self-management practices and improve outcomes from limited health resources.

Abstract
Background Lymphedema of the leg and its advanced form, known as elephantiasis, are significant causes of disability and morbidity in areas endemic for lymphatic filariasis (LF), with an estimated 14 million persons affected worldwide. The twin goals of the World Health Organization’s Global Program to Eliminate Lymphatic Filariasis include interrupting transmission of the parasitic worms that cause LF and providing care to persons who suffer from its clinical manifestations, including lymphedema—so-called morbidity management and disability prevention (MMDP). Scaling up of MMDP has been slow, in part because of a lack of consensus about the effectiveness of recommended hygiene-based interventions for clinical lymphedema. Methods and Findings We conducted a systemic review and meta-analyses to estimate the effectiveness of hygiene-based interventions on LF-related lymphedema. We systematically searched PubMed, Embase, ISI Web of Knowledge, MedCarib, Lilacs, REPIDISCA, DESASTRES, and African Index Medicus databases through March 23, 2015 with no restriction on year of publication. Studies were eligible for inclusion if they (1) were conducted in an area endemic for LF, (2) involved hygiene-based interventions to manage lymphedema, and (3) assessed lymphedema-related morbidity. For clinical outcomes for which three or more studies assessed comparable interventions for lymphedema, we conducted random-effects meta-analyses. Twenty-two studies met the inclusion criteria and two meta-analyses were possible. To evaluate study quality, we developed a set of criteria derived from the GRADE methodology. Publication bias was assessed using funnel plots. Participation in hygiene-based lymphedema management was associated with a lower incidence of acute dermatolymphagioadenitis (ADLA), (Odds Ratio 0.32, 95% CI 0.25–0.40), as well as with a decreased percentage of patients reporting at least one episode of ADLA during follow-up (OR 0.29, 95% CI 0.12–0.47). Limitations included high heterogeneity across studies and variation in components of lymphedema management. Conclusions Available evidence strongly supports the effectiveness of hygiene-based lymphedema management in LF-endemic areas. Despite the aforementioned limitations, these findings highlight the potential to significantly reduce LF-associated morbidity and disability as well as the need to develop standardized approaches to MMDP in LF-endemic areas. The tropical disease lymphatic filariasis (LF) causes chronic swelling of the leg—lymphedema—in 14 million people worldwide. To stop the spread of LF, a program led by the World Health Organization (WHO) offers annual preventive drug treatment to affected communities. For people who already have lymphedema, WHO recommends simple hygiene-based measures that include skin care and limb movement. Yet only a small proportion of those with LF-related lymphedema have been trained in these measures. To determine the effectiveness of hygiene-based lymphedema management, we reviewed the scientific literature. Twenty-two studies were found that 1) used hygiene-based interventions to manage lymphedema; 2) measured the effect of these interventions; and 3) were done in an area where LF occurs. Overall, use of hygiene-based measures was associated with 60% lower odds of inflammatory episodes, known as “acute attacks,” in the affected limb. Acute attacks cause severe pain, fever, and disability, and they make lymphedema worse. Hygiene and sanitation are necessary for control of many tropical diseases. Hygiene is also effective for managing LF-related lymphedema and reducing suffering caused by acute attacks. Training people with lymphedema in hygiene-based interventions should be a priority for LF programs everywhere.

Abstract
We conducted a longitudinal analysis of 117 lymphedema patients in a filariasis-endemic area of Haiti during 1995-2008. No difference in lymphedema progression between those who received or did not receive mass drug administration (MDA) was found on measures of foot (P = 0.24), ankle (P = 0.87), or leg (P = 0.46) circumference; leg volume displacement (P = 0.09), lymphedema stage (P = 0.93), or frequency of adenolymphangitis (ADL) episodes (P = 0.57). Rates of ADL per year were greater after initiation of MDA among both groups (P < 0.01). Nevertheless, patients who received MDA reported improvement in four areas of lymphedema-related quality of life (P ≤ 0.01). Decreases in foot and ankle circumference and ADL episodes were observed during the 1995-1998 lymphedema management study (P ≤ 0.01). This study represents the first longitudinal, quantitative, leg-specific analysis examining the clinical effect of diethylcarbamazine on lymphedema progression and ADL episodes.

Abstract
One of the two main goals of the Global Programme to Eliminate Lymphatic Filariasis (LF) is to provide care for those suffering from the devastating clinical manifestations of this filarial infection. Among the 120 million infected people worldwide, up to 16 million have lymphoedema. The WHO strategy for managing lymphoedema is based on rigorous skin hygiene, exercise, antibiotics and antifungals when indicated. The aim is to reduce acute attacks of adenolymphangitis and cellulitis responsible for lymphoedema progression and disability. The objective of our study was to assess the effectiveness of home-based lymphoedema management implemented by the national health system of Burkina Faso. Any patient was eligible to participate in the study if suffering from LF-related lymphoedema of a lower limb at any stage, and receiving care as part of the health education and washing project between April 2005 and December 2007. The primary readout was the occurrence of an acute attack in the month preceding the consultation reported by the patient or observed by the care-giver. In all, 1089 patients were enrolled in the study. Before lymphoedema management intervention, 78.1% (95%CI: 75.5-80.5) of the patients had an acute attack in the month preceding the consultation; after four and half months of lymphoedema management, this was reduced to 39.1% (95%CI: 36.2-42.1). A reduction of acute attacks related to the number of consultations or related to the patients' age and gender was not observed. Our results suggest that the home-based lymphoedema management programme in the primary health care system of Burkina Faso is effective in reducing morbidity due to LF in the short-term (4.5 months). The lymphoedema management requires no additional human resources, but whether its effect can be sustained remains to be seen.

Abstract
AIM The aim of this study was to know the correlation of patients' 3 months recall on acute dermato-lymphangio-adenitis (ADLA) with anti-streptolysin O (ASO) serology and its application as a tool to know the burden of ADLA in the community. METHODS Fifty-nine lymphoedema (LE) patients and 27 age matched controls were clinically assessed for LE and the occurrence of ADLA during the previous 3 months was obtained by recall. After obtaining the informed consent, 2 mL of venous blood sample was collected and ASO was quantified in Olympus AU400 auto-analyzer. RESULTS When the results were computed as two groups, controls and LE patients with no reported ADLA and LE patients with reported ADLA (by 3 months recall), the ASO positivity and ASO titre was significantly higher in the later group (P < 0.05). When the results were computed as three groups, controls with no reported ADLA, LE patients with no reported ADLA and LE patients with reported ADLA, the ASO titre was significantly higher in LE patients reported ADLA (P < 0.05). CONCLUSION As ASO was measured in post-infection phase, we relied on the ASO titre for making conclusion. Patients' 3 months recall on ADLA correlates with the ASO titre and therefore, it could be considered as a tool to measure the burden of ADLA in the community. Multicentre community-based studies are needed to ascertain the findings.

Reduction in acute filariasis morbidity during a mass drug administration trial to eliminate lymphatic filariasis in Papua New Guinea. PLoS Negl Trop Dis 2011; 5:e1241. [PMID: 21765964 PMCID: PMC3134431 DOI: 10.1371/journal.pntd.0001241] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/21/2010] [Accepted: 06/02/2011] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Acute painful swelling of the extremities and scrotum are debilitating clinical manifestations of Wuchereria bancrofti infection. The ongoing global program to eliminate filariasis using mass drug administration is expected to decrease this and other forms of filarial morbidity in the future by preventing establishment of new infections as a consequence of eliminating transmission by the mosquito vector. We examined whether mass treatment with anti-filarial drugs has a more immediate health benefit by monitoring acute filariasis morbidity in Papua New Guinean communities that participated in a 5-year mass drug administration trial. METHODOLOGY/PRINCIPAL FINDINGS Weekly active surveillance for acute filariasis morbidity defined by painful swelling of the extremities, scrotum and breast was performed 1 year before and each year after 4 annual mass administrations of anti-filarial drugs (16,480 person-years of observation). Acute morbidity events lasted <3 weeks in 92% of affected individuals and primarily involved the leg (74-79% of all annual events). The incidence for all communities considered together decreased from 0.39 per person-year in the pre-treatment year to 0.31, 0.15, 0.19 and 0.20 after each of 4 annual treatments (p<0.0001). Residents of communities with high pre-treatment transmission intensities (224-742 infective bites/person/year) experienced a greater reduction in acute morbidity (0.62 episodes per person-year pre-treatment vs. 0.30 in the 4(th) post-treatment year) than residents of communities with moderate pre-treatment transmission intensities (24-167 infective bites/person/year; 0.28 episodes per person-year pre-treatment vs. 0.16 in the 4(th) post-treatment year). CONCLUSIONS Mass administration of anti-filarial drugs results in immediate health benefit by decreasing the incidence of acute attacks of leg and arm swelling in people with pre-existing infection. Reduction in acute filariasis morbidity parallels decreased transmission intensity, suggesting that continuing exposure to infective mosquitoes is involved in the pathogenesis of acute filariasis morbidity.

Feasibility and effectiveness of basic lymphedema management in Leogane, Haiti, an area endemic for bancroftian filariasis. PLoS Negl Trop Dis 2010; 4:e668. [PMID: 20422031 PMCID: PMC2857874 DOI: 10.1371/journal.pntd.0000668] [Citation(s) in RCA: 38] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/18/2009] [Accepted: 03/12/2010] [Indexed: 11/24/2022] Open
Abstract
Background Approximately 14 million persons living in areas endemic for lymphatic filariasis have lymphedema of the leg. Clinical studies indicate that repeated episodes of bacterial acute dermatolymphangioadenitis (ADLA) lead to progression of lymphedema and that basic lymphedema management, which emphasizes hygiene, skin care, exercise, and leg elevation, can reduce ADLA frequency. However, few studies have prospectively evaluated the effectiveness of basic lymphedema management or assessed the role of compressive bandaging for lymphedema in resource-poor settings. Methodology/Principal Findings Between 1995 and 1998, we prospectively monitored ADLA incidence and leg volume in 175 persons with lymphedema of the leg who enrolled in a lymphedema clinic in Leogane, Haiti, an area endemic for Wuchereria bancrofti. During the first phase of the study, when a major focus of the program was to reduce leg volume using compression bandages, ADLA incidence was 1.56 episodes per person-year. After March 1997, when hygiene and skin care were systematically emphasized and bandaging discouraged, ADLA incidence decreased to 0.48 episodes per person-year (P<0.0001). ADLA incidence was significantly associated with leg volume, stage of lymphedema, illiteracy, and use of compression bandages. Leg volume decreased in 78% of patients; over the entire study period, this reduction was statistically significant only for legs with stage 2 lymphedema (P = 0.01). Conclusions/Significance Basic lymphedema management, which emphasized hygiene and self-care, was associated with a 69% reduction in ADLA incidence. Use of compression bandages in this setting was associated with an increased risk of ADLA. Basic lymphedema management is feasible and effective in resource-limited areas that are endemic for lymphatic filariasis. Lymphatic filariasis is a parasitic disease that is spread by mosquitoes. In tropical countries where lymphatic filariasis occurs, approximately 14 million people suffer from chronic swelling of the leg, known as lymphedema. Repeated episodes of bacterial skin infection (acute attacks) cause lymphedema to progress to its disfiguring form, elephantiasis. To help achieve the goal of eliminating lymphatic filariasis globally, the World Health Organization recommends basic lymphedema management, which emphasizes hygiene, skin care, exercise, and leg elevation. Its effectiveness in reducing acute attack frequency, as well as the role of compressive bandaging, have not been adequately evaluated in filariasis-endemic areas. Between 1995 and 1998, we studied 175 people with lymphedema of the leg in Leogane, Haiti. During Phase I of the study, when compression bandaging was used to reduce leg volume, the average acute attack rate was 1.56 episodes per year; it was greater in people who were illiterate and those who used compression bandages. After March 1997, when hygiene and skin care were emphasized and bandaging discouraged, acute attack frequency significantly decreased to 0.48 episodes per year. This study highlights the effectiveness of hygiene and skin care, as well as limitations of compressive bandaging, in managing lymphedema in filariasis-endemic areas.

Addiss DG, Brady MA. Morbidity management in the Global Programme to Eliminate Lymphatic Filariasis: a review of the scientific literature. FILARIA JOURNAL 2007; 6:2. [PMID: 17302976 PMCID: PMC1828725 DOI: 10.1186/1475-2883-6-2] [Citation(s) in RCA: 98] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 03/16/2006] [Accepted: 02/15/2007] [Indexed: 11/23/2022]
Abstract
The Global Programme to Eliminate Lymphatic Filariasis (GPELF) has two major goals: to interrupt transmission of the parasite and to provide care for those who suffer the devastating clinical manifestations of the disease (morbidity control). This latter goal addresses three filariasis-related conditions: acute inflammatory episodes; lymphoedema; and hydrocele. Research during the last decade has confirmed the importance of bacteria as a cause of acute inflammatory episodes in filariasis-endemic areas, known as acute dermatolymphangioadenitis (ADLA). Current lymphoedema management strategies are based on the central role of ADLA as a trigger for lymphoedema progression. Simple intervention packages are in use that have resulted in dramatic reductions in ADLA rates, a lower prevalence of chronic inflammatory cells in the dermis and subdermis, and improvement in quality of life. During the past decade, the socioeconomic impact of ADLA and lymphoedema in filariasis-endemic areas has received increasing attention. Numerous operational research questions remain to be answered regarding how best to optimize, scale up, monitor, and evaluate lymphoedema management programmes. Of the clinical manifestations targeted by the GPELF, hydrocele has been the focus of the least attention. Basic information is lacking on the effectiveness and complications of hydrocele surgery and risk of post-operative hydrocele recurrence in filariasis-endemic areas. Data on the impact of mass administration of antifilarial drugs on filarial morbidity are inconsistent. Several studies report reductions in acute inflammatory episodes, lymphoedema, and/or hydrocele following mass drug administration, but other studies report no such association. Assessing the public health impact of mass treatment with antifilarial drugs is important for programme advocacy and morbidity control strategies. Thus, although our knowledge of filariasis-related morbidity and its treatment has expanded in recent years, much work remains to be done to address the needs of more than 40 million persons who suffer worldwide from these conditions.

Abstract
Lymphatic filariasis is a disease of considerable socioeconomic burden in the tropics. Presently used antifilarial drugs are able to strongly reduce transmission and will thus ultimately lower the burden of morbidity associated with the infection, however, a chemotherapeutic principle that directly induces a halt or improvement in the progression of the morbidity in already infected individuals would constitute a major lead. In search of such a more-effective drug to complement the existing ones, in an area endemic for bancroftian filariasis in Ghana, 33 microfilaremic and 18 lymphedema patients took part in a double-blind, placebo-controlled trial of a 6-wk regimen of 200 mg/day doxycycline. Four months after doxycycline treatment, all patients received 150-200 microg/kg ivermectin and 400 mg albendazole. Patients were monitored for Wolbachia and microfilaria loads, antigenemia, filarial dance sign (FDS), dilation of supratesticular lymphatic vessels, and plasma levels of lymphangiogenic factors (vascular endothelial growth factor-C [VEGF-C] and soluble vascular endothelial growth factor receptor-3 [(s)VEGFR-3]). Lymphedema patients were additionally monitored for stage (grade) of lymphedema and the circumferences of affected legs. Wolbachia load, microfilaremia, antigenemia, and frequency of FDS were significantly reduced in microfilaremic patients up to 24 mo in the doxycycline group compared to the placebo group. The mean dilation of supratesticular lymphatic vessels in doxycycline-treated patients was reduced significantly at 24 mo, whereas there was no improvement in the placebo group. Preceding clinical improvement, at 12 mo, the mean plasma levels of VEGF-C and sVEGFR-3 decreased significantly in the doxycycline-treated patients to a level close to that of endemic normal values, whereas there was no significant reduction in the placebo patients. The extent of disease in lymphedema patients significantly improved following doxycycline, with the mean stage of lymphedema in the doxycycline-treated patients being significantly lower compared to placebo patients 12 mo after treatment. The reduction in the stages manifested as better skin texture, a reduction of deep folds, and fewer deep skin folds. In conclusion, a 6-wk regimen of antifilarial treatment with doxycycline against W. bancrofti showed a strong macrofilaricidal activity and reduction in plasma levels of VEGF-C/sVEGFR-3, the latter being associated with amelioration of supratesticular dilated lymphatic vessels and with an improvement of pathology in lymphatic filariasis patients.
