    Abstract Kidney transplant remains the definitive treatment for patients with end-stage renal disease. A retrospective cohort was conducted in Dr. Selma Center for Kidney Diseases (DSCKD) to determine the pattern of follow-up and outcomes of adult kidney transplant recipients (KTRs) on long-term follow-up. Patients presented for follow-up during the period from January to June 2018 were studied regarding their demographic features, kidney transplant surgery, immunosuppressive therapy, graft function, and post-transplant complications. Data analysis was done using the Statistical Package for the Social Sciences version 16.0. During the study period, a total of 941 adult and pediatric KTR presented to DSCKD for follow-up. Only 792 KTRs were included in the study; those were adults, with their first kidney transplant, completed one year post-transplant, and agreed for enrollment. The mean age of the studied population was 47 ± 4.3 years. The majority were males, 74.2%. The median duration of follow-up was 7.4 years (interquartile range 3-11). Most transplants were through living-related donations, 78.8%. The combination of prednisolone, tacrolimus, and azathioprine remains the most common immunosuppressive regimen prescribed; delivered to 47.5% of recipients. Post-transplant complications were predominantly recurrent infections, diabetes mellitus, and hyperlipidemia seen in 54.5%, 42.4%, and 24.7% of recipients, respectively. On cross-comparisons living unrelated donor transplant recipients were found to have increased post-transplant complications, with a reduced kidney graft function at the end of the 1

On cross-comparisons living unrelated donor transplant recipients were found to have increased post-transplant complications, with a reduced kidney graft function at the end of the 1st year and throughout follow-up, when compared to living related donor transplant recipients. A prospective multi-center study with long-term follow-up remains essential for further evaluation of the long-term outcomes of the KTR in Sudan.

    Abstract Few controlled trials have studied the treatment of relapse in adults with minimal change disease. Repeated courses of steroids, cyclophosphamide, cyclosporine and even mycophenolate mofetil (MMF), all seem to play a role. The aim of this study was to review and critically analyze the literature regarding the use of immunosuppressive therapy for the treatment of relapse in adults with minimal change nephrotic syndrome (MCNS). An intensive search was done for published trials in the general medical database. Retrieved studies were further sorted according to specific inclusion and exclusion criteria. Selected trials were critically analyzed and evaluated using the Oxford Centre for Evidence-based Medicine Levels of Evidence, 2009 rating. Six studies were selected and systematically reviewed. One randomized controlled trial compared the use of cyclo-phosphamide versus cyclosporine (11 adults) and showed that both drugs are effective in the treatment of frequent relapses [level 1b evidence (grade B)]. Three trials (total of 20 patients) tested the use of cyclosporine therapy and showed that cyclosporine, though effective in the treatment of relapse, is associated with an extremely high incidence of subsequent relapses following drug with-drawal. A long-term follow-up cross-sectional study of 95 patients, with 69 relapsers, supported the use of steroids in the treatment of occasional relapses [level 2c evidence (grade C)]. One case series described the benefits of MMF [level 4 evidence (grade C)]. Most of the the clinical trials studied were heterogeneous, underpowered by small adult populations, open-labelled, non-randomized, with poor statistical analysis, validity and utility. We conclude that there is poor evidence that successful treatment of the first relapse of adult MCNS can be achieved with a second course of steroids or cyclosporine. Also, there is weak evidence that frequent relapses can be treated using cyclophosphamide, cyclosporine or MMF. Powered, multi-centered, randomized, blinded, controlled trials, with long-term follow-up are required to know the optimal treatment for relapsing adult MCNS.

    Abstract Background: Hepatitis C virus (HCV) is a global public health problem, with ~ 11 million people in Africa infected. There is incomplete information on HCV in Sudan, particularly in haemodialysis patients, who have a higher prevalence compared to the general population. Thus, our objectives were to genotype and molecularly characterize HCV isolated from end-stage renal disease haemodialysis patients.
    Methods: A total of 541 patients were recruited from eight haemodialysis centres in Khartoum and screened for anti-HCV. Viral loads were determined using in-house real-time PCR in seropositive patients. HCV was genotyped and subtyped using sequencing of amplicons of 5' untranslated (UTR) and non-structural protein 5B (NS5B) regions, followed by phylogenetic analysis of corresponding sequences.
    Results: The HCV seroprevalence in the study was 17% (93/541), with HCV RNA-positive viremic rate of 7% (40/541). A low HCV load, with a mean of 2.85 × 10
    Conclusion: HCV infection is highly prevalent in haemodialysis patients from Sudan, with phylogenetic analysis intimating nosocomial infection. HCV genotyping is useful to locate potential transmission chains and to enable individualized treatment using highly effective direct-acting antivirals (DAAs).

    Abstract Kidney transplantation remains the preferred modality of treatment for patients with end-stage renal disease. In Sudan, kidney transplantation accounted for 28% of the total provided renal replacement therapies. A cross-sectional, hospital-based study was conducted in hemodialysis (HD) units in Khartoum State during the period from September 2010 to January 2011. It aimed to determine the main reasons for the currently low renal transplantation rate. Data were obtained by direct interviewing using a specifically pre-coded and pre-tested questionnaire following a pilot study. A total of 462 adult HD patients were randomly selected from the various HD units in Khartoum State; these patients accounted for 16.9% of the total HD population in Khartoum State. The mean age of the study patients was 48.5 ± 23.6 years and 312 (67.5%) were males. Upon interviewing, only 316 patients (68.4%) said that they had been counseled for kidney transplantation. One hundred and twenty-two patients (26.4%) were on the active transplant list; of these, 50% preferred to have their kidney transplantation performed abroad, mostly due to the availability of commercial transplantation and/or a presumed better outcome. The low renal transplantation rate was due to financial constraints in 112 patients (24.2%), lack of medical fitness in 97 patients (21%) and absence of a suitable kidney donor in 92 patients (20%), while 56 patients (12%) were still having misperceptions regarding transplantation and preferred to continue on dialysis. To improve the kidney transplantation rate in Khartoum State, the Sudan program for organ transplantation is expected to take more initiatives to promote and improve the outcome of kidney transplants inside the country and, accordingly, regain the patients' confidence on the health system.
