RESUMO
This article describes two ethical dilemmas encountered by our research team during a project working with undocumented immigrants in Toronto, Canada. This article aims to be transparent about the problems the research team faced, the processes by which we sought to understand these problems, how solutions were found, and how the ethical dilemmas were resolved. Undocumented immigrants are a vulnerable community of individuals residing in a country without legal citizenship, immigration, or refugee status. There are more than half a million undocumented immigrants in Canada. Through an academic-community partnership, a study was conducted to understand the experiences of undocumented immigrants seeking health care in Toronto. The lessons outlined in this article may assist others in overcoming challenges and ethical dilemmas encountered while doing research with vulnerable communities.

BACKGROUND: Rheumatoid arthritis (RA) is an autoimmune disorder that affects the small joints of the body. It is one of the leading causes of chronic morbidity in high-income countries, but little is known about the burden of this disease in low- and middle-income countries (LMIC). METHODS: The aim of this study was to estimate the prevalence of RA in six of the World Health Organization's (WHO) regions that harbour LMIC by identifying all relevant studies in those regions. To accomplish this aim various bibliographic databases were searched: PubMed, EMBASE, Global Health, LILACS and the Chinese databases CNKI and WanFang. Studies were selected based on pre-defined inclusion criteria, including a definition of RA based on the 1987 revision of the American College of Rheumatology (ACR) definition. RESULTS: Meta-estimates of regional RA prevalence rates for countries of low or middle income were 0.40% (95% CI: 0.23-0.57%) for Southeast Asian, 0.37% (95% CI: 0.23-0.51%) for Eastern Mediterranean, 0.62% (95% CI: 0.47-0.77%) for European, 1.25% (95% CI: 0.64-1.86%) for American and 0.42% (95% CI: 0.30-0.53%) for Western Pacific regions. A formal meta-analysis could not be performed for the sub-Saharan African region due to limited data. Male prevalence of RA in LMIC was 0.16% (95% CI: 0.11-0.20%) while the prevalence in women reached 0.75% (95% CI: 0.60-0.90%). This difference between males and females was statistically significant (P < 0.0001). The prevalence of RA did not differ significantly between urban and rural settings (P = 0.353). These prevalence estimates represent 2.60 (95% CI: 1.85-3.34%) million male sufferers and 12.21 (95% CI: 9.78-14.67%) million female sufferers in LMIC in the year 2000, and 3.16 (95% CI: 2.25-4.05%) million affected males and 14.87 (95% CI: 11.91-17.86%) million affected females in LMIC in the year 2010. CONCLUSION: Given that majority of the world's population resides in LMIC, the number of affected people is substantial, with a projection to increase in the coming years. Therefore, policy makers and health-care providers need to plan to address a significant disease burden both socially and economically.
