The African Association of Nephrology was founded in Cairo on 28 February 1987, during the ISN-sponsored “African Kidney and Electrolytes Conference”, being hosted and co-sponsored by the Egyptian Society of Nephrology. Twenty-five physicians interested in kidney disease, from 13 African countries, constituted the core assembly that selected a steering committee composed of five members, representing the five geographical zones in Africa. The committee proposed the name the African Association of Nephrology (AFRAN), approved its logo, defined its mission, and drafted its constitution. All were ratified at the first General Assembly meeting held in London in July of the same year. The steering committee was re-elected to continue as the Executive Committee for the first cycle and mandated to set the scene for future meetings, publications and programmes. AFRAN congresses have been held regularly ever since, triennially for three cycles, then biennially with a few exceptions. Scientific meetings including Continuing Medical Education activities and hands-on workshops addressing local kidney and electrolyte disorders, have been held in most African countries, with generous logistical and financial support by the International Society of Nephrology (ISN). The abstracts of the first congress were published in Kidney International. Meeting proceedings were usually distributed by hand, thanks to representatives of pharmaceutical companies in the various African countries. A quarterly newsletter was edited and published in the Sudan, upgraded to a journal (the African Journal of Nephrology) in 1997 and self-published from Egypt until the editorial office moved to South Africa in 2012. A registry of nephrologists and dialysis units in Africa was compiled and published from Algeria in 1989, then updated in the Sudan a few years later. More recently, an African Renal Registry was established, now hosted in South Africa. Numerous fellowships were offered by the better-off countries to their emerging neighbours, being sponsored by international organizations, mainly the ISN. Joint research has been conducted mainly through these fellowships. By its 10th birthday, AFRAN had encompassed all African countries, to become the official pan-African federation of national renal societies. The ISN initiatives for supporting the developing world, originally operated under the umbrella of the Commission for the Global Advancement of Nephrology (COMGAN), were instrumental in supporting AFRAN’s foundation and sustainability. Besides the ISN, AFRAN became affiliated to many other regional and all national societies of nephrology, which qualified it to serve as the principal liaison between African nephrology and that in the rest of the world.

Now that we have successfully migrated to our new online platform, AJN has taken the additional step of adopting a “publish-as-you-go” strategy. Articles will be published once they have been accepted and there will no longer be the usual wait until the next issue is published. New articles will be added throughout the year and will therefore be available to be read and cited much sooner. The latest articles which we are now publishing include a short review by Halperin on the assessment of the renal response in patients with potassium disorders. Halperin first gave us the well-known transtubular K+ gradient (TTKG) but in recent years has been recommending the use of the urine K+/creatinine ratio instead. In this article he explains the reasons for this change. Kapembwa et al. present their data on technique survival in patients on peritoneal dialysis (PD) at Tygerberg Hospital in Cape Town. Successfully maintaining patients on PD is especially important when a PD-first policy is being followed, as is the case at their centre. The issue of the access of rural patients with chronic kidney disease to healthcare is the topic of the paper by Singh et al., who report on referral patterns at a tertiary centre in Durban, South Africa. The paper by Camara et al., from the Free State province, South Africa, describes the outcomes of patients with acute kidney injury who needed continuous renal replacement therapy. In their cohort, patients with HIV infection were substantially younger and had a much worse outcome. Finally, the report by Makhoba et al. describes a case of osseous metaplasia in a renal allograft.

As the official journal of the African Association of Nephrology (AFRAN), the African Journal of Nephrology (AJN) publishes research on kidney diseases by African and other researchers. AJN has reached a significant milestone in this first issue of Volume 20. This is the first issue which was prepared and published using our new web-based platform. We wish to take this opportunity to thank the editorial board, the reviewers and the authors for their role in the successful migration to the new platform. To mark this milestone, and to coincide with the March 2017 AFRAN/AFPNA Congress in Cameroon, we are delighted to publish a special article on the history of AFRAN by Professor Rashad Barsoum, one of the co-founders of AFRAN. Contributions to the success of AFRAN by the International Society of Nephrology, and by colleagues from Europe, America and Africa, are acknowledged. This is an illustrated story of our association told by its founding president, which is now immortalised in AJN. This issue also features an original article reporting on malignant kidney tumours in Port Harcourt, Nigeria. Nephroblastoma and renal cell carcinoma remain the leading kidney malignancies, as also reported worldwide. Finally, two interesting case reports conclude this issue: a case of IgG4-related nephropathy and a successful pregnancy in a patient on chronic haemodialysis.

Focal segmental glomerulosclerosis (FSGS) is a well-defined pattern of glomerular injury identifiable on renal biopsy using light microscopy. FSGS is not a single entity and much information is needed to make a proper evaluation in each subject with the condition to identify the cause, prognosticate, and inform treatment choices. Categories of information required include: clinical presentation, responsiveness to steroids, pathological subtype, genetic background, and evidence for other adaptive, viral, and toxic causes. Primary FSGS describes a cohort of conditions identified by exclusion of known contributory causes, but does not represent a single entity. Clinical manifestations and outcomes of FSGS vary widely; they include asymptomatic proteinuria, cases of spontaneous remission, steroid-sensitive nephrotic syndrome, and nephrotic syndrome resistant to immune modulating therapy progressing to end-stage renal disease with recurrence after transplantation. Although immune modulating therapy (based notably on corticosteroids and calcineurin inhibitors) are widely used in primary FSGS, robust evidence of their efficacy remains scant.

During the last decade, recombinant human erythropoietin has revolutionised the management of renal anaemia. It is highly effective in the vast majority of patients treated, causing enhanced erythropoiesis and a rise in haemoglobin concentration. This has resulted not only in amelioration of uraernic symptoms, but there has also been objective evidence of improved quality-of-life, exercise capacity, and cardiac function [I]. The most striking benefits seen have been progression of left ventricular hypertrophy which is known to account for much of the high cardiovascular morbidity and mortality seen in dialysis patients. and thus the arguments for correcting renal anaemia is now overwhelming. There is also an improvement in nutrition following erythropoietin therapy, over and above the improvement in appetite associated with correction of the anaemia.

A patient with end-stage kidney disease due to chronic glomerulonephritis was initiated on continuous ambulatoryperitoneal dialysis. After three years he was transferred to haemodialysis following recurrent episodes of peritonitis. After the commencement of haemodialysis the patient developed progressive abdominal distension; paracentesisrevealed bloody ascites. Radiographic imaging revealed features of small bowel obstruction with bowel loops matted tothe posterior abdominal wall. A diagnosis of encapsulating peritoneal sclerosis was made. Treatment with prednisonewas initiated but the patients condition steadily worsened and he demised a year later due to severe malnutrition andsepsis.

In this issue of the African Journal of Nephrology (AJN Vol 18, No 1) we publish original articles ranging from the prevalence of chronic kidney disease in an African population in general, to the role of HIV in kidney disease. An elegant study of fractionated heparin use in haemodialysis is also presented. Continuous ambulatory peritoneal dialysis is an important modality of renal replacement to be considered in Africa in view of its ease of operation. However, beware of potential complications including sclerosing peritonitis as reported in Cape Town (South Africa).As in the past, this issue covers a wide variety of topics with contributions from diverse authors from south to west and North Africa. On behalf of the editorial board, I wish to take this opportunity to thank all of the authors and reviewers who have contributed to this issue of the journal, as well as to the readers for their sustained interest in the African Journal of Nephrology.
