Transplant: The Success of Renal Transplant Programs.

In the absence of malignancy or other severe comorbidity, kidney transplantation offers better survival rates and quality of life than dialysis. Despite this survival advantage, many lower- and upper-middle-income countries do not offer adequate kidney transplant services. This is particularly troubling because end-stage kidney disease often is more common in these countries than in high-income countries and overall is less costly in the life of a patient. We describe the contrasting levels of provision of kidney transplantation in Mexico, India, Nigeria, Ghana, and Zimbabwe, and kidney transplant services for children in Africa.

COVID-19 Pandemic: Is Africa Different?

COVID-19 has now spread to all the continents of the world with the possible exception of Antarctica. However, Africa appears different when compared with all the other continents. The absence of exponential growth and the low mortality rates contrary to that experienced in other continents, and contrary to the projections for Africa by various agencies, including the World Health Organization (WHO) has been a puzzle to many. Although Africa is the second most populous continent with an estimated 17.2% of the world's population, the continent accounts for only 5% of the total cases and 3% of the mortality. Mortality for the whole of Africa remains at a reported 19,726 as at August 01, 2020. The onset of the pandemic was later, the rate of rise has been slower and the severity of illness and case fatality rates have been lower in comparison to other continents. In addition, contrary to what had been documented in other continents, the occurrence of the renal complications in these patients also appeared to be much lower. This report documents the striking differences between the continents and within the continent of Africa itself and then attempts to explain the reasons for these differences. It is hoped that information presented in this review will help policymakers in the fight to contain the pandemic, particularly within Africa with its resource-constrained health care systems.

Recognizing true H5N1 infections in humans during confirmed outbreaks.

INTRODUCTION: The goal of this study was to evaluate whether any characteristics that are evident at presentation for urgent medical attention could be used to differentiate cases of H5N1 in the absence of viral testing. METHODOLOGY: Information about exposure to poultry, clinical signs and symptoms, treatments, and outcomes was abstracted from existing data in the global avian influenza registry (www.avianfluregistry.org) using standardized data collection tools for documented and possible cases of H5N1 infection who presented for medical attention between 2005-2011 during known H5N1 outbreaks in Azerbaijan, Indonesia, Pakistan and Turkey. RESULTS: Demography, exposure to poultry, and presenting symptoms were compared, with only the common symptoms of fever and headache presenting significantly more frequently in confirmed H5N1 cases than in possible cases. Reported exposure to  infected humans was also more common in confirmed cases. In contrast, unexplained respiratory illness, sore throat, excess sputum production, and rhinorrhea were more frequent in possible cases. Overall, oseltamivir treatment showed a survival benefit, with the greatest benefit shown in H5N1 cases who were treated within two days of symptom onset (51% reduction in case fatality). CONCLUSION: Since prompt treatment with antivirals conferred a strong survival benefit for H5N1 cases, presumptive antiviral treatment should be considered for all possible cases presenting during an outbreak of H5N1 as a potentially life-saving measure.

Barriers to a functional renal transplant program in developing countries.

A successful kidney transplantation offers the best possible quality of life for patients with end stage renal disease (ESRD). Despite this, renal transplantation rates in the developing world (as with other modalities of renal replacement therapy) are considerably lower than in the developed world. Identified reasons for this include poverty, low education levels of the populations of these countries, the absence of functional dialysis and transplant units with adequately trained and motivated staff, and the lack of appropriate health policies derived from renal registry data. Measures to improve the quality of care should center around improvement of the socioeconomic and political scenario in these countries. The peculiarities of renal transplantation in these countries are also discussed.

End-stage renal disease in sub-Saharan Africa.

End-stage renal disease (ESRD) is increasing to epidemic proportions worldwide. In most parts of sub-Saharan African, poor leadership and resultant poverty have resulted in low detection and management of ESRD. Many countries in the subregion do not have the resources, both material and manpower, to cope with the number of ESRD patients, even when detected. The Committee for the Global Advancement of Nephrology (COMGAN) and the International Society of Nephrology (ISN) site visits to the region have gone a long way to increase awareness. ISN-sponsored scholarships to doctors in the region have also served to improve the availability of needed manpower. The need to enhance preventive programs and the promotion and development of renal transplantation as an option are suggested modalities for coping with ESRD in this region.

Hemodialysis: management problems in developing countries, with Nigeria as a surrogate.

The incidence of end-stage renal failure is increasing worldwide at an annual growth rate of 8%. Data for much of the developing world are often unavailable, but given the prevalence of poor socioeconomic factors, the incidence is likely to be greater. In Sub-Saharan Africa, economic and manpower factors dictate a conservative approach to therapy in most instances. The majority of those with end-stage renal disease (ESRD) perish because of the lack of funds, as very few can afford regular maintenance dialysis and renal transplantation is often not available. Hemodialysis (HD) remains the most common modality of management, with a very few units offering peritoneal dialysis (PD). Limitations to regular maintenance HD include the paucity of dialysis units, restriction of those units to urban centers, and the absence of government funding or subsidy and health insurance to cover the relatively high costs of dialysis. The few available units are bedeviled with multiple problems: old machines frequently break down, absence of adequate maintenance technical support and spare parts, and frequent power outages. Staff motivation and remuneration are equally poor with consequent disruption of services due to industrial action and emigration of trained staff to the Middle East and Western world. Present avenues for improvements include: focusing on prevention to stem the high prevalence of ESRD, greater government involvement to better fund units and thus enhance the quality of services rendered, and the wider availability of transplantation.
