RESUMEN
The burden of chronic kidney disease (CKD) has increased exponentially worldwide but more so in low- and middle-income countries. Specific risk factors in these regions expose their populations to an increased risk of CKD, such as genetic risk with APOL1 among populations of West African heritage or farmers with CKD of unknown etiology that spans various countries across several continents to immigrant/indigenous populations in both low- and high-income countries. Low- and middle-income economies also have the double burden of communicable and noncommunicable diseases, both contributing to the high prevalence of CKD. The economies are characterized by low health expenditure, sparse or nonexistent health insurance and welfare programs, and predominant out-of-pocket spending for medical care. This review highlights the challenges in populations with CKD from low-resource settings globally and explores how health systems can help ameliorate the CKD burden.

BACKGROUND: In 2008, several Nigerian children developed acute kidney injury (AKI) after ingesting teething syrup contaminated with diethylene glycol (DEG). Because there are limited diagnostic facilities in resource-constrained countries, this study investigated whether AKI associated with DEG could be identified by other means. METHODS: This was a multicenter study. Information was obtained from hospital records. Clinicopathological features of all children with AKI over a 6-month period were reviewed. RESULTS: Sixty (50.4%) of 119 children ingested "My pikin" teething syrup. Compared to children who had not ingested it, they were significantly (p < 0.05) younger (11.95 vs. 31 months), more were anuric (98.3 vs. 74.6%), hypertensive (84 vs. 52%), had severe metabolic acidosis (46.7 vs. 20.5%), and died (96.6 vs. 71.2%). They developed increasing metabolic acidosis and multiorgan dysfunction despite peritoneal dialysis. Late presentation, financial difficulties, inadequate facilities for toxicology, and hemodialysis complicated management. CONCLUSIONS: Identifying AKI associated with DEG is difficult. Detailed drug history, increasing metabolic acidosis, and multiorgan deterioration despite peritoneal dialysis should arouse suspicion. Simple diagnostic tests need to be developed and facilities for hemodialysis of infants and financial support provided. Recurrences can be prevented by creating awareness, improving manufacturing practices, field-testing of drugs, and international monitoring of pharmaceuticals imported for manufacture.

OBJECTIVE: To elicit the explanatory models (EM) of hypertension among patients in a hospital-based primary care practice in Nigeria. Design. Semi-structured in-depth individual interviews and focus groups were conducted with 62 hypertensive patients. Interviews and focus groups were audiotaped and transcribed verbatim. Data analysis was guided by phenomenology and content analysis using qualitative research software ATLAS.ti 5.0. RESULTS: Patients expressed four categories of EM of hypertension: (1) perceptions of hypertension, (2) consequences, (3) effect on daily life, and (4) perception of treatment. Focus group discussions and individual interviews yielded a wide range of insights into the social and cultural factors influencing patients' beliefs and health behavior. Participants were aware of the risks of hypertension. There was disagreement between participants' own understanding of the serious nature of hypertension, the need for long-term treatment, and the desire to take long-term medication. Participants acknowledged the use of traditional medicine (e.g., teas and herbs) and healers. Different themes emerged for men versus women such that women often focused on family issues while men tended to discuss external stressors stemming from work as a cause of hypertension. Men were concerned with frequent urination, decreased libido, and erectile dysfunction. CONCLUSION: Knowledge gained will inform development of patient-centered treatment plans and targeted behavioral and educational interventions.
