Developing a Care Program for Neglected Patient Groups: Oculocutaneous Albinism

June 2020

Oculocutaneous albinism (OCA) is a rare genetic disorder that all physicians learn about in medical school, but it may never again cross your mind as a practicing dermatologist in the United States. However, in developing countries, particularly across Africa, being born with OCA makes you vulnerable to serious physical and psychosocial consequences, and even human rights violations. In an increasingly connected world, it is important to understand how skin conditions can affect patients worldwide and to learn what interventions can improve quality of life (QoL).

We present a brief overview of OCA and describe the efforts that a US dermatologist initiated to improve care for people living with albinism (PWA) in Botswana.

Clinical Features and Management
OCA is an autosomal recessive disorder caused by a defect in the melanin production pathway, leading to various levels of hypopigmentation in the skin, hair, and eyes.1,2 OCA has an estimated worldwide incidence of 1 in 17,000 births, but rates as high as 1 in 1000 births are reported in certain parts of Africa, and up to 1 in 70 people worldwide may carry a gene for this condition.1-3 There are 7 recognized clinical subtypes of OCA with variable amounts of depigmentation determined by the specific genetic defect involved, and most patients have mutations in either the TYR, OCA2, TYRP1, or SLC45A2 loci.1,2 Because melanin-producing cells are crucial for development of the visual pathway, all PWA have some level of visual dysfunction such as congenital nystagmus, strabismus, photophobia, foveal hypoplasia, and reduced visual acuity in the range of 20/60 to 20/400, rendering many legally blind.1,2 OCA is diagnosed clinically based on recognition of the characteristic visual defects in association with reduced skin/hair/eye pigmentation.1-3

 Because melanin absorbs UV light, the main health risk to PWA is increased susceptibility to photodamage and early onset skin cancers.4,5 Squamous cell carcinoma is the most common type of skin cancer seen in OCA, with a reported 1000-times greater risk in PWA in Africa compared with the general population.2-6

In developing countries, PWA face greater risks of morbidity and mortality from treatable skin cancers due to limited access to health care.2-5 Additionally, lack of access to appropriate eye care leaves many PWA to needlessly go through life functionally disabled with blindness.3 Therefore, management for OCA takes a preventive approach, including sun protection practices and frequent skin checks, to reduce the risk of sun damage and subsequent skin cancers. For eye health, glasses and sun-protective eyewear are critical, and management should include a full ophthalmologic exam as early as possible to diagnose potentially treatable visual defects.

Figure 1Psychosocial impact. In Africa, being visibly white among a society of predominantly dark skin creates challenges of inequality. Pervasive myths and superstitions attached to OCA in African culture include fear of contagion or bad luck, a belief that sexual intercourse with PWA cures HIV/AIDS, and the belief that the body parts of PWA can bring good fortune in rituals by traditional healers.3,7,8 These myths fuel stigma and discrimination, which prevent PWA from being accepted by society and even among their own family. Low QoL with feelings of shame, depression, and helplessness can often be the result. Alarmingly, persecution, rape, ritualized murder, and selling of the body parts of PWA have become frequent occurrences across central and southern Africa.3,7,8 The United Nations Human Rights Council has recognized the significance of this human rights issue in a call to action, mandating that nations adopt protective and supportive measures for this special population.9

Developing an Albinism Care Program
In Botswana, a developing country in sub-Saharan Africa with one of the world’s highest HIV/AIDS burdens,10 OCA is still a neglected issue. There are no established disability laws to guarantee PWA equal rights and protection from stigma and discrimination. The government funds a public health care system,11 but patients still face difficulties due to hospitals that are overburdened, undersupplied, and understaffed.

In 2016, Dr Victoria Williams started working full time as the only dermatology specialist for the Ministry of Health (MOH) of Botswana through the Botswana-University of Pennsylvania (UPenn) Partnership. As Head of Dermatology at Princess Marina Hospital (PMH), the only dermatology clinic in the public health care system at that time, Dr Williams noticed there was little community awareness about OCA. PWA, mostly from rural areas with low health care access, would present to clinic with severe sun damage and advanced skin tumors, leading to disfigurement and even death. Most disturbingly, patients had little understanding of their condition or their health care needs. Critical knowledge on the need to get skin checks, eye exams, signs of skin cancer, and how to protect themselves from the sun were lacking. Further, poor vision made it difficult for them to become educated, get a job, or be meaningfully included within society. With the aim to improve the health and QoL of PWA, Dr Williams developed the first albinism support programs in Botswana during her 2 years working as a dermatologist in the country. 

Clinical care interventions. The first priority was obtaining equipment to allow early treatment of figure 2premalignant and malignant skin lesions: cryotherapy spray cannisters, a liquid nitrogen dewar storage container, curettes, and an electrodessicator. More importantly, a workflow for sustainable access to liquid nitrogen and equipment sterilization was established within the hospital system.

Two clinic days per month were dedicated to OCA in order to streamline supplies and preparation for procedural treatment of skin cancers, allow patients to be seen on a walk-in basis, and sensitize hospital staff to prioritize the needs of this population. PWA were given priority to be evaluated and dispensed prescriptions in the morning, to protect them from the dangerous UV exposure of the midday sun. 

Sunscreen program. The next priority was to address sun damage prevention. Dr Williams obtained a Skincare in Developing Countries Grant from the American Academy of Dermatology to support the development of a sunscreen distribution program. After extensive research, it was determined that purchasing wholesale bulk sunscreen from South Africa and packaging it locally would be the most cost-effective and sustainable method. Thus, Dr Williams began personally packaging 200-g tubs and dispensing them to patients during skin checks. A log was created to track the demographics of PWA receiving sunscreen from the dermatology clinic in order to begin collecting the first epidemiological data on OCA in Botswana.

To ensure sustainability of the program, Dr Williams obtained support from a local nongovernmental organization, the Lady Khama Charitable Trust, to continue funding bulk sunscreen purchase. Currently, the packaging and distribution of sunscreen is transitioning to the pharmacy department at PMH to improve patient access and sustainability. 

Education and awareness. After establishing improved clinical care systems, the focus shifted to patient and community perceptions. To provide key education to patients about their disease, focused handouts were created to explain OCA health needs and sun protection advice in the local language. These were provided to patients along with counseling during their skin checks (Figure 1).

figure 3However, cultural change was needed. To improve awareness on a large scale, Dr Williams worked with local albinism organizations to pioneer the first local celebration of International Albinism Awareness Day (IAAD) on June 14, 2016, which has continued annually. Events have consisted of educational lectures about the associated skin/eye health, psychosocial, and educational needs of OCA (Figure 2); a fashion show modeling sun protection by PWA; skin and eye screenings; and a sun protection booth to distribute and counsel on the use of sunscreen, hats, sunglasses, and umbrellas (Figure 3). 

,

In 2019, through the support of an extension in funding from the Skincare in Developing Countries Grant, Dr Williams conducted educational outreach programs in underserved regions of Botswana: Francistown, Maun, and Ghanzi. Each outreach site received lectures on albinism, a skin cancer education poster, and various dermatology resources. Providers were also trained to utilize teledermatology resources to allow continued communication with dermatologists for assistance in caring for patients with albinism and other skin conditions. 

To help change public perception of OCA, educational information is shared through radio, television, and newspapers leading up to the yearly IAAD. In addition, a beauty pageant and confidence-building bootcamp is held annually to boost albinism awareness, help normalize the disease, and give a visual demonstration that PWA are as beautiful, intelligent, and capable as other members of society (Figure 4).

Discussion
Neglected populations, particularly those with visible skin disease and disabilities, need to feel that they have the support of key societal institutions like the health care system. Through implementation of a multimodal support program, we have significantly improved quality of care for PWA in Botswana and observed patients with OCA being more proactive about their health. PWA have a new sense of confidence that health care providers can understand their unique needs and help them. This positive support, in turn, empowers PWA to engage in activities to improve their own QoL.

Our albinism care program started through the efforts of one person but has been expanded and sustained by the ongoing cooperation of many in the health care system and private sector in Botswana. Dr Bwanali Jereni, now the Director of Dermatology at PMH, currently directs the albinism care programs locally, while Dr Williams provides remote and in-person support through her position at the UPenn. PMH now has a multidisciplinary team of providers that have been trained on albinism care. In 2019, our care program was recognized as the Best Innovative Service Project in the country by the MOH of Botswana, demonstrating the nationwide impact this work has attained in increasing OCA awareness.

A key part of the program is sun damage prevention, because sunscreen access can be incredibly challenging in developing countries. Local production is a cost-lowering option that has been exemplified by the Kilimanjaro Sunscreen Production Unit in Tanzania.12 However, sunscreen manufacturing requires significant up-front funding and local regulations prevented this method from being used in Botswana. We offer our method of bulk purchase and local packaging to highlight another feasible option for those looking to create a sunscreen program with limited resources. Bulk purchase from an established supplier ensures quality and allows negotiation for price reduction. Local packaging is simple and can be done by clinicians, volunteers, or pharmacy staff. Costs can be further reduced and compliance reinforced by having patients obtain refills using the same container. 

Across Africa, various organizations are working to improve QoL for PWA,12-19 and we offer our experience in Botswana as an example of how to start a program with limited resources and scale up. It is important to share program designs and experiences to allow others to emulate successful components. Standing Voice, a UK-based nongovernmental organization, has developed large-scale comprehensive albinism support programs in east Africa,12,15,18,19 and their successes provided significant inspiration for the design of our albinism program. For those interested in creating a care program targeting a neglected skin disease, we suggest focusing on the key areas of education, access to care, and awareness. We were able to evoke positive changes for patients with OCA in Botswana through:

  • increasing awareness about OCA within the health care system;
  • obtaining equipment to support treatment of precancers and skin cancers in dermatology clinic;
  • increasing ease of access to dermatology clinics;
  • developing a sustainable system for free sunscreen distribution; 
  • educating patients about albinism, sun protection, and their own health care needs;
  • increasing awareness and support for OCA within Botswana society; and
  • strengthening social support programs for PWA in Botswana.

Looking to the future, we aim to initiate outreach skin and eye care support services to increase access to care for rural populations. We also strive to increase disability rights with provisions for equitable educational support, employment opportunities and social inclusion. 

As dermatologists, our goal should be to uphold the human rights of our patients as well as to increase awareness and support for all vulnerable and neglected patient populations. We hope that as more physicians are able to understand the unique physical and psychosocial needs of PWA, awareness and support to ensure their health and well-being will be prioritized in all countries.
