With Bare Feet in the Soil: Podoconiosis, a Neglected Cause of Tropical Lymphoedema

Sero-antigen prevalence of lymphatic filariasis and risk factors of podoconiosis in Busiriba sub-county, Kamwenge district, Southwestern Uganda, August-September 2018

OBJECTIVE

Given the neglected nature of filariasis, especially in Uganda where data are scarce, this cross-sectional study aimed to determine the sero-antigen prevalence of lymphatic filariasis and risk factors associated with non-lymphatic filariasis (podoconiosis) in Busiriba Sub-county, Kamwenge District, Uganda, during August-September 2018, to inform targeted elimination efforts.

RESULTS

We enrolled 101 participants, among whom 35 (34.7%) had podoconiosis. The sero-antigen prevalence of lymphatic filariasis was 1.0%. Older age and walking barefoot were associated with increased podoconiosis risk. Specifically, individuals aged 25-49 years with had 7.38 times higher odds of podoconiosis (adjusted odds ratio [aOR] = 7.38, 95% CI: 1.36-40.13) compared to those under 25 years, while those aged ≥ 50 years had even higher odds (aOR = 8.49, 95%CI: 1.44-50.15). Additionally, individuals who reported walking barefoot had 14 times higher odds of podoconiosis (aOR = 14.08; 95% CI: 2.49-79.50).

Impairment of health-related quality of life and its determinants among patients with podoconiosis in East Wollega Zone, Oromia Regional State, Ethiopia: institutional-based cross-sectional study

OBJECTIVE

This study aimed to assess the impairment of health-related quality of life (HRQoL) and its determinants among patients diagnosed with podoconiosis in East Wollega Zone, Oromia Regional State, Ethiopia.

METHODS

An institutional-based cross-sectional study design was used in the setting of primary healthcare facilities to assess impaired HRQoL among patients with podoconiosis in the East Wollega Zone from 1 March 2023 to 30 April 2023, using the Dermatologic Life Quality Index (DLQI). Data was collected from 494 patients with podoconiosis, and a multistage sampling technique was employed. The data was entered into EpiData V.4.6 and exported to SPSS V.27 for analysis. A linear regression model with a 95% cofidence interval (CI) was used to estimate level of HRQoL and to identify its determinants estimating beta (β) coefficient declaring the significance level at p<0.05.

RESULTS

The quality of life among patients was impaired on average by 9.6±6.1 with the lowest DLQI Score in the domain of treatment (0.8±0.97) and the highest in the domain of daily activity (2.3±1.72). The identified significant determinants of impairment of HRQoL associated with DLQI scores were duration of disease (95% CI, β=0.11 (0.08 to 0.15)), acute dermato-lymphangio-adenitis (ADLA) (95% CI, β=0.08 (0.01 to 0.16)), comorbidity (95% CI, β=1.26 (0.37 to 2.16)), consistently wearing shoes (95% CI, β=-0.06 (-0.09 to -0.03)), feeling of stigmatised (95% CI, β=0.21 (0.16 to 0.25)) and psychological distress (95% CI, β=0.17 (0.14 to 0.21)) and being female (95% CI, β=1.16 (0.19 to 2.12)).

CONCLUSION

Overall, HRQoL among patients with podoconiosis was moderately impaired. The duration of disease, ADLA, comorbidity, stigma, psychological distress and being female in sex significantly impaired HRQoL, whereas consistently wearing shoes significantly improved HRQoL among the patients with podoconiosis. Therefore, healthcare providers and public health experts should work on educating communities and counselling patients to avoid stigma and psychological distress, wearing shoes consistently and treating podoconiosis and other comorbidities among these patients.

'We no longer experience the same pain': a cross-sectional study assessing the impact of Heart and Sole Africa's podoconiosis prevention education program

BACKGROUND

Podoconiosis is a non-infectious neglected tropical disease caused by long-term exposure to irritant volcanic soils. It results in severe physical, psychological and financial consequences. Heart and Sole Africa (HASA) is a non-governmental, community-based organization providing management to podoconiosis patients in Rwanda. We sought to analyze the impact of their program on the lives of patients.

METHODS

Quantitative surveys recorded the participants' demographics, adherence to HASA's management recommendations and changes in quality of life (QOL). Qualitative questions were used to gather respondent perspectives on HASA programming.

RESULTS

We interviewed 127 patients from HASA's Musanze (n=47) and Burera (n=80) clinics. Almost all participants (98.4%) reported statistically significant (p<0.01) improvements in their QOL, and more than one-half (51.2%) had a favorable adherence score of >80%. Qualitative feedback identified specific challenges to adherence and recognition of program success in symptom management.

CONCLUSIONS

Our study demonstrated the value of community-based podoconiosis programming in improving the lives of patients. Practices such as regular feet washing, emollient application, shoe wearing and limb raising can result in a marked reduction of morbidity. Our findings support the argument for scaling up these management practices across Rwanda.

'My feet cannot stand on their own': podoconiosis patient healthcare expenditures and income impacts in Rwanda

BACKGROUND

Podoconiosis is a progressive and debilitating form of tropical lymphoedema endemic to Rwanda. Although the physical and psychological consequences are well known, few studies have evaluated the financial burden of podoconiosis.

METHODS

This cross-sectional, quantitative study aimed to characterize direct treatment costs and impacts on annual earnings among individuals living with podoconiosis. Participants from two highly endemic districts were invited to complete a survey focused on health-seeking history, insurance status, out-of-pocket costs and income changes. Direct treatment costs included medical expenditures (consultation, diagnostics, medication) and non-medical expenditures (food, transportation, accommodation).

RESULTS

Overall, 226 adults (≥18 y of age) diagnosed with podoconiosis participated. Most had access to community-based health insurance (91.6%) but were unable to work (71.7%). Respondents sought care from health centres/posts (61.9%), hospitals (25.1%), traditional healers (5.8%) and/or community health workers (4.0%). On average, study participants paid US$32.50 (range US$0-779.23) annually, or 11.7% of their household salary, on podoconiosis treatments.

CONCLUSIONS

This study demonstrates the significant financial burden of podoconiosis on individuals and their communities. Increased attention on integrating podoconiosis management into primary care systems and testing cost-effective solutions is needed to protect those who are most vulnerable.

Phenotypical characterization, and antibiotics susceptibility patterns of skin bacteria found in podoconiosis patients in the North West Region of Cameroon

BACKGROUND

Podoconiosis, a non-infectious disease originating from long-term exposure of bare feet to irritant red clay soil is a lifelong, disabling disease with no specific diagnostic tool, classified into 5 stages based on the severity of leg swelling (lymphoedema). Secondary bacterial infections have been suggested to cause acute dermatolymphangioadenitis (ADLA) attacks and drive disease progression. Although the North West Region of Cameroon has a proven history of podoconiosis endemicity, the bacterial composition of lymphoedema due to this condition has not been studied. Thus, this study investigated the leg bacterial diversity of patients who suffered from the lymphoedema and their susceptibility pattern to selected antibiotics.

METHODS

A cross-sectional study was carried out in which podoconiosis affected and non-lymphoedema individuals living in the same community were purposively selected. Samples were collected by swabbing the skin between the toes and around the anklebone, then cultured and sub-cultured on nutrient agar to obtain pure isolates. The cultured isolates were then morphologically and biochemically classified using microscopy and analytic profile index test kits, respectively. The disk diffusion technique was used to determine antibiotic susceptibility.

RESULTS

Thirty-three participants were recruited, and 249 bacterial isolates were characterized into 29 genera, 60 species; with 30 (50%) being gram positive rods, 19 (31.7%) gram positive cocci, and 11 (18.3%) gram negative rods. Thirteen gram positive rods, fifteen gram positive cocci, and eight gram negative rods of bacterial species were found only in podoconiosis individuals among which Cellulomonas spp / Microbacterium spp. (2.8%), Staphylococcus lentus (3.3%), and Burkholderia cepacia (4.0%) dominated. 90% (90%) of the bacterial isolates were sensitive to doxycycline, whereas ampicillin had a high level of intermediate resistance, and penicillin G had the greatest resistant profile.

CONCLUSION

Our findings show that 94 (37.8%) out of 249 described bacterial isolates were exclusively found in the legs of podoconiosis individuals, and their susceptibility pattern to antibiotics was similar to that of others.

Genital Lymphedema after Cancer Treatment: A Narrative Review

Genital lymphedema may affect males and females after cancer treatment (gynecological, such as cervical, uterine or ovarian, melanoma, prostate, anus…). It is frequently associated with lower limb lymphedema, and is responsible for discomfort, cosmetic disfigurement and functional disturbances. Impacts on body image, sexual function and quality of life are major, and difficult to explore because cancer treatment itself and lymphedema are so closely interwoven. Local complications, e.g., papillomatosis, warty growth, lymph vesicles with embarrassing lymph oozing and cellulitis, may occur. Usual lymphedema therapies, like bandaging and elastic compression, are poorly adapted to these sites. Surgery, essentially based on cutaneous resection techniques, is the primary symptomatic treatment; it achieves good efficacy, in adults and children, with possible recurrence requiring reintervention.

Health-related quality of life and associated factors among adult podoconiosis patients in Debre Elias district Northwest, Ethiopia

Background

Podoconiosis is endemic non-filarial elephantiasis and non-infective neglected tropical disease. It has a wide impact on the physical, social and psychological aspects of the well-being of a person. However, limited information is available about the disease burden on health-related quality of life and associated factors in Ethiopia.

Objective

This study aimed is to determine health-related quality of life and associated factors among adult podoconiosis patients in Debre Elias district, Northwest, Ethiopia.

Methods

A community-based cross-sectional study was conducted from February 1 to March 30, 2020 in the Debre Elias district. A multi-stage stratified; systematic random sampling technique was employed to select 403 podoconiosis patients. The data were collected through an interviewer-administered questionnaire. Data were entered into Epi data version 4.6 and exported to STATA version 14 for analysis. After the assumption check for the linear regression model, simple and multiple regression was done to see the association between the predictor and outcome variables. Predictor variables that had p-value <0.2 at simple linear regression were taken into multiple linear regression. β coefficient with 95% CI and p-value of <0.05 was considered as statistically significant variables in multiple linear regression analysis.

Result

The overall mean quality of life score among podoconiosis patients was 61.93±17.14. The mean quality of life score for the physical, psychological, social, and environmental domains were 75.57±21.86, 60.43±18.58, 30.34±10.46, and 81.38±22.77 respectively. Foot care had a statically significant association with all domains. Higher quality of life podoconiosis patients was associated with foot care. Lower quality of life was associated with the presence of anxiety, advanced stage of the disease, and frequent adenolymphangitis attack.

Conclusion

Social and psychological domains of quality of life were lowest as compared to physical and environmental domains of quality of life. Early medical treatment, psychosocial support, and home-based foot care should be encouraged to improve the quality of life in podoconiosis patients.

Podoconiosis: is a disease that affects the lymph vessels of the lower extremities and is caused by a person’s foot exposed to minerals found in red clay soil. Podoconiosis has been identified in 32 countries and globally 4 million people are affected with this disease. The disease is characterized by prominent swelling) of the lower extremities, it can be prevented through keeping good foot hygiene, wearing clean socks and shoes daily and covering floor in the home to avoid contact with irritant soil. Patients with podoconiosis significantly challenged by physical disability, poor mental health and social discrimination. This study identified quality of life and associated factors among adult podoconiosis patients in Debre Elias district Northwest, Ethiopia. Specifically, we addressed quality of life score for physical, psychological, social and environmental domain. We found from this study foot care had statically significant association with all domains. Lower quality of life was associated with presence of anxiety, advanced stage of the disease and frequent adenolymphangitis attack. Social and psychological domains of quality of life were lowest as compared to physical and environmental domains of quality of life. Therefore, this study encouraged early medical treatment, home-based foot care and psychosocial support to improve quality of life in podoconiosis patient.

Family-based intervention for prevention and self-management of disabilities due to leprosy, podoconiosis and lymphatic filariasis versus usual care in Ethiopia: study protocol for a cluster-randomised controlled trial

INTRODUCTION

Leprosy, podoconiosis and lymphatic filariasis (LF) are three skin-related neglected tropical diseases. All three conditions can lead to temporary and permanent impairments. These impairments progressively worsen and are major determinants of stigma, discrimination and participation restrictions. Self-care is essential to prevent disabilities and chronic disease complications. Many persons with leprosy-related, LF-related and podoconiosis-related disabilities need to practice self-management routines their entire life. This is difficult without support and encouragement of others. The objective of this study was to assess the effectiveness of a family-based intervention in terms of physical outcomes related to prevention and self-management of disabilities due to leprosy, podoconiosis and LF and family quality of life and well-being compared with usual practice and care.

METHODS AND ANALYSIS

The study will use a cluster-randomised controlled trial design with two study arms. The project will be carried out in endemic districts in East and West Gojjam zones in the Amhara region in Ethiopia. Clusters consist of kebeles (lower administrative structures in the district) that have been merged, based on their geographical proximity and the number of cases in each kebele. A total of 630 participants will be included in the study. The intervention group will consist of 105 persons affected by leprosy, 105 persons affected by LF or podoconiosis, and 210 family members. The control group will consist of 105 persons affected by leprosy and 105 persons affected by LF or podoconiosis. The family-based intervention comprises an essential care package that consists of the following three main components: (1) self-management of disabilities, (2) economic empowerment and (3) psychosocial support. Participants in the control areas will receive usual practice and care. Data analysis includes, but is not limited to, calculating the percentage of change and corresponding 95% CI of physical impairment outcomes in each group, before and after the intervention is implemented, effect sizes, intention to treat and difference in difference analysis.

ETHICS AND DISSEMINATION

Ethical approval has been obtained from the Debre Markos University Health Sciences Institutional Research Ethics Review Committee. Results will be disseminated through peer-reviewed publications, conference presentations and workshops.

Podoconiosis instruction at nursing schools in Kenya, Rwanda, and Uganda

BACKGROUND

Podoconiosis is a preventable, progressive, and non-infectious form of elephantiasis that can contribute to significant disability and economic burden when not treated early. Nurses play a critical role in early detection and response in rural Africa, but it is unclear if they receive adequate training on podoconiosis. We aimed to characterize podoconiosis instruction at all government accredited, post-secondary nursing institutions in three African countries.

METHODS

Data for this cross-sectional study was collected through a quantitative survey with several open-answer questions. Through a rigorous online search, we identified all post-secondary institutions in Kenya, Rwanda and Uganda accredited to teach human nursing. A total of 289 accredited programs, including 85 certificate, 56 degree and 148 diploma programs were invited to participate. Respondents completed surveys online or by telephone. Measures focused on podoconiosis knowledge, perceptions of quality/quantity of podoconiosis instruction, and barriers to sufficient podoconiosis education.

RESULTS

We obtained information about 212 curricula across 149 nursing institutions in the three countries (participation rate: 73.4%). Podoconiosis coverage was limited across programs (certificate-24.1%; diploma-55.6%; degree-30.3%). Most respondents felt that the quality and quantity of instruction were insufficient (60.6%, 62.9%), respectively. Exclusion from government curricula, low priority and faculty lack of knowledge were commonly reported barriers to podoconiosis inclusion.

CONCLUSIONS

This study demonstrated clear gaps in podoconiosis training for nurses across the three countries and highlights a serious challenge in eliminating podoconiosis as a public health problem. Interventions to improve nurses' knowledge could include the development and free distribution of podoconiosis teaching materials, designed for integration into pre-existing courses.

A family-based intervention for prevention and self-management of disabilities due to leprosy, podoconiosis and lymphatic filariasis in Ethiopia: A proof of concept study

A key issue for persons with leprosy-, lymphatic filariasis- and podoconiosis-related disabilities is the life-long need to practice self-management routines. This is difficult to sustain without regular encouragement and support of others. Family-based support may be a sustainable and feasible strategy to practice self-management routines. This proof of concept study aimed to develop and pilot a family-based intervention to support prevention and self-management of leprosy, lymphatic filariasis and podoconiosis-related disabilities in Ethiopia.

We used a quasi-experimental pre/post intervention study design with a mixed methods approach. The study population included persons affected by leprosy, lymphatic filariasis and podoconiosis and their family members. All persons affected had visible impairments due to their condition. We collected physical impairment outcomes, data on activity limitations, stigma and family quality of life using the SALSA scale (range 0–80), the SARI stigma scale (range 0–63) and the Beach Centre Family Quality of Life scale (range 0–125) and conducted in-depth interviews and focus group discussions. Quantitative data were analysed using paired t-tests, unequal variances t-tests, linear regression and binary logistic regression. Qualitative data were coded using open, inductive coding and content analysis.

The family-based intervention consisted of self-management of disabilities, awareness raising and socio-economic empowerment. The intervention was delivered over several monthly group meetings over the course of several months. A total of 275 (100%) persons affected attended at least one session with a family member, and 215 (78%) attended at least three sessions. There was no significant improvement in eye and hand problems after the intervention. However, foot and leg impairments, number of acute attacks, lymphedema and shoe wearing all significantly improved at follow-up. In addition, family quality of life significantly improved from 67.4 at baseline to 89.9 at follow-up for family members and from 76.9 to 84.1 for persons affected (p<0.001). Stigma levels significantly decreased from 24.0 at baseline to 16.7 at follow-up (p<0.001). Activity levels improved, but not significantly.

This proof of concept study showed that the family-based intervention had a positive effect on impairments and self-management of disabilities, family quality of life and stigma. We recommend a large-scale efficacy trial, using a randomised controlled trial and validated measurement tools, to determine its effectiveness and long-term sustainability.

'Far from the views of decision-makers': podoconiosis instruction at medical schools across endemic countries in Africa

BACKGROUND

Podoconiosis is a neglected tropical disease that causes significant physical, emotional and financial suffering, especially among impoverished rural farmers. Sufficient physician training is integral to optimizing patient outcomes through timely diagnosis and appropriate management. Therefore we sought to characterize podoconiosis instruction offered to medical students in endemic African countries.

METHODS

We invited faculty from 170 medical schools in all podoconiosis-endemic African countries to provide information about podoconiosis inclusion in medical curricula. Surveys were available in French and English and captured podoconiosis knowledge, quantity/quality of instruction, ranking of importance relative to other diseases and barriers for improvement. Respondents voluntarily shared responses online or by telephone.

RESULTS

Study participants provided information about curricula at 97 medical schools across 14 countries. In total, 42.6% of schools across nine countries offered podoconiosis-specific instruction; most respondents felt that the quality (60.4%) and quantity (61.5%) of instruction was insufficient. Common barriers to sufficient training included exclusion from government curricula, prioritization according to caseload and scarce epidemiological data.

CONCLUSIONS

Our study demonstrates widespread neglect in podoconiosis training for physicians in endemic countries. Government support is needed to ensure curricula match the needs of health workers practicing in rural, low-income regions.

Podoconiosis in Rwanda: Knowledge, attitudes and practices among health professionals and environmental officers

Background

Podoconiosis is a neglected tropical disease commonly found in volcanic regions, where soil is rich in silica. It usually manifests as bilateral lower limb edema. The majority of people affected by podoconiosis are farmers who do not wear shoes. The condition was recently documented in all 30 districts in Rwanda but knowledge, attitudes and practices (KAP) of Rwandan health professionals and environmental officers towards podoconiosis are unknown.

Methodology/Findings

The objective of this study was to assess the knowledge, attitudes and practices (KAP) of Rwandan health providers and environmental officers towards podoconiosis in order to improve patient healthcare experiences and health outcomes, and to reduce stigma against affected individuals. To achieve this goal, we administered a KAP assessment to physicians (N = 13), nurses/midwives (N = 59), community health workers (N = 226), and environmental officers (N = 38) in the third highest podoconiosis prevalence district in Rwanda (Musanze).

All 336 respondents had heard of podoconiosis, but 147 (44%) respondents correctly identified soil as the only direct cause of podoconiosis. The awareness of signs and symptoms and risk groups was lower than any other category (31.5% and 47.5%, respectively). The overall attitude toward podoconiosis was positive (86.1%), with CHWs least likely to harbor negative beliefs against podoconiosis patients. One particular area where most respondents (76%) expressed negative attitude was that they saw people with podoconiosis as a threat to their own health and their family’s health. Prescription of antibiotics and use of ointments/soap to manage wounds was low (5% and 32.2%, respectively), in part due to supply shortages at health facilities.

Conclusions

This study identified clear gaps in health provider knowledge and practices that affect patient care for those with podoconiosis. Improved access to essential medicines at health facilities and podoconiosis-focused training sessions for practicing health providers are necessary to minimize the burden and stigma of affected individuals.

Podoconiosis is a foot disease that progressively affects genetically susceptible people who do not wear shoes in volcanic soil. This disease causes disability, stigma, and impinges on people’s economic productivity. In Rwanda, it is estimated that 6429 people live with podoconiosis, but health services for these particular patients are almost nonexistent. We evaluated knowledge, attitudes and practice among 298 health professionals and 38 environmental officers and found that only 44% of all respondents knew that soil is the only direct cause of podoconiosis. Few health professionals (6%) reported having treated a podoconiosis patient and most health professionals (79%) identified shortages of critical drugs and supplies as an important barrier to providing treatment. Three quarters of environmental officers (74%) did not know that farmers are the people most vulnerable to this condition. The poor knowledge of all respondents toward podoconiosis and the lack of medical supplies suggest that podoconiosis patients likely receive substandard medical care and receive little credible information on prevention. We recommend a multi-sectoral approach to training, as well as the engagement of governments and the World Health Organization, to avail medications and treatment materials in the community.

Magnitude of Podoconiosis and Its Associated Factors among an Adult Population in Waghmra Zone, Ethiopia: A Cross-Sectional Study

Background

Podoconiosis is one of the neglected tropical diseases, and it is a nonfilarial elephantiasis caused by prolonged barefoot exposure to irritant soil. This is manifested by slowly progressive swelling of the foot and lower leg which may lead to an irreversible disability among affected people. Podoconiosis is an entirely noncommunicable preventable disease with a low-cost preventive mechanism. This study is aimed at assessing the magnitude and factor affecting Podoconiosis in Waghmra zone, Amhara region, Ethiopia, 2019.

Methods

A community-based cross-sectional study was conducted among 808 household members. A multistage sampling method was used to select study participants. A pretested semistructured questionnaire, observation, and clinical screening were used to collect data. The data were entered using EpiData version 4.2 and analyzed using SPSS version 24.0. Both bivariable and multivariable logistic regression models were fitted to identify factors associated with Podoconiosis. Odds ratio with 95% confidence interval was computed to determine the level of significance; in multivariable analysis, variables with a P value less than 0.05 were considered as statistically significant.

Result

According this study's results, 4.3% of study participants were affected by Podoconiosis. A family number of four and above [AOR = 3.29, 95% CI (1.013-10.661)], family income of less than 500 ETB [AOR = 3.69, 95% CI (1.271-10.727)], distance from a health facility greater than 3 km [AOR = 6.69, 95% CI (1.610-27.863)], no shoe wearing habits [AOR = 5.02, 95% CI (1.969-12.778)], age at first wearing of shoes at 10 and above [AOR = 4.46, 95% CI (1.792-11.102)], and no feet washing habits [AOR = 3.87, 95% CI (1.516-9.883)] are significant factors of Podoconiosis.

Conclusion

Creating awareness about the importance of shoe wearing, feet hygiene, and building infrastructure such as a road, health facility, and water supply were essential preventive strategies. Training about early diagnosis and effective management of lymphedema, giving emphasis on hygiene education and sanitation program, and reporting any suspected Podoconiosis case as early as possible are some of the recommendations forwarded.
