Background: By the time of histological confirmation of rejection is achieved, renal scarring may for treatment as a realistic option . This study aims to study the subclinical pathological graft data and to evaluate the histopathological impact of different immunosuppression protocols in pediatric renal transplant recipients. Methods: This is a case series that included twenty living donor renal transplant recipients. All included cases received the classic triple immunotherapy for at least one month post-transplantation [Steroids, calconurine inhibitors (CNI), and mycofenlolic mofetile (MMF)]. Based on their immunological risk stratification; included cases were divided into 2 groups: group (A) continued on CNI based triple therapy protocol; group (B) shifted to evirolimus /low dose CNI protocol. Surveillance biopsies were done for all cases at one and four month post-transplantation. Results: One and four month biopsies revealed subclinical rejection (including borderline changes) in 4 (20%) cases and 6 (30%) cases respectively. The number of patients received tacrolimus/MMF therapy significantly increased (p=0.02) while that of patients on everloimus/low dose CNI significantly decreased (p=0.014) due to drug modifications based on four month surveillance biopsy data. Conclusion: Subclinical rejection is not uncommon in pediatric renal graft recipients which makes surveillance biopsy might be of help. Early usage of evirolimus/low CNI protocol is associated with higher rejection rate than triple therapy.

For the World Kidney Day Steering Committee Kidney disease is a global public health problem that affects more than 750 million persons worldwide. The burden of kidney disease varies substantially across the world, as does its detection and treatment. Although the magnitude and impact of kidney disease is better defined in developed countries, emerging evidence suggests that developing countries have a similar or even greater kidney disease burden. In many settings, rates of kidney disease and the provision of its care are defined by socioeconomic, cultural, and political factors, leading to significant disparities in disease burden, even in developed countries. These disparities exist across the spectrum of kidney disease - from preventive efforts to curb development of acute kidney injury or chronic kidney disease, to screening for kidney disease among persons at high risk, to access to subspecialty care and treatment of kidney failure with renal replacement therapy. World Kidney Day 2019 offers an opportunity to raise awareness of kidney disease and highlight disparities in its burden and current state of global capacity for prevention and management. In this editorial, we highlight these disparities and emphasize the role of public policies and organizational structures in addressing them. We outline opportunities to improve our understanding of disparities in kidney disease, the best ways for them to be addressed, and how to streamline efforts toward achieving kidney health equity across the globe.Для Организационного комитета Всемирного дня почки Заболевания почек - глобальная проблема общественного здравоохранения, затрагивающая более 750 млн человек во всем мире Распространенность заболеваний почек, а также их диагностика и лечение в разных странах существенно различаются. Значение и последствия заболеваний почек наиболее хорошо изучены в развитых странах, но в последнее время появляется все больше данных, свидетельствующих об аналогичной и даже более высокой распространенности заболеваний почек и в развивающихся странах. Во многих ситуациях частота заболеваний почек и обеспечение медицинской помощью определяются социально - экономическими, культурными и политическими факторами, что даже в развитых странах приводит к существенным различиям наносимого болезнью ущерба. Эти различия наблюдаются на разных этапах оказания помощи при заболеваниях болезнях почек: от профилактических мероприятий, направленных на предотвращение развития острого повреждения почек и хронической болезни почек, до скрининга на наличие болезни почек у лиц с высоким риском заболевания и доступа к специализированной медицинской помощи и проведению заместительной почечной терапии для лечения почечной недостаточности. Всемирный день почки - 2019 дает возможность повысить осведомленность о заболеваниях почек, а также осветить несоответствия между причиняемым ими ущербом и потенциальными возможностями их профилактики и лечения. В публикуемой передовой статье мы хотим заострить внимание на этих несоответствиях и подчеркиваем роль общественной политики и организационных структур в их устранении. Мы намечаем пути улучшения понимания этих различий, определяем основные подходы к достижению этого понимания, а также возможности оптимизации усилий для обеспечения равенства в вопросах поддержания здоровья почек во всем мире.

World Kidney Day 2019 offers an opportunity to raise awareness of kidney disease and highlight disparities in its burden and current state of global capacity for prevention and management. Here, we highlight that many countries still lack access to basic diagnostics, a trained nephrology workforce, universal access to primary health care, and renal replacement therapies. We point to the need for strengthening basic infrastructure for kidney care services for early detection and management of acute kidney injury and chronic kidney disease across all countries and advocate for more pragmatic approaches to providing renal replacement therapies. Achieving universal health coverage worldwide by 2030 is one of the World Health Organization's Sustainable Development Goals.

Resumo A doença renal é um problema de saúde pública global, afetando mais de 750 milhões de pessoas em todo o mundo. O ônus da doença renal varia substancialmente em todo o mundo, assim como sua detecção e tratamento. Em muitos contextos, as taxas de doença renal e a provisão de seus cuidados são definidas por fatores socioeconômicos, culturais e políticos que levam a disparidades significativas. O Dia Mundial do Rim 2019 oferece uma oportunidade para aumentar a conscientização sobre doenças renais e destacar as disparidades em seu impacto e estado atual da capacidade global de prevenção e tratamento. Aqui, destacamos que muitos países ainda carecem de acesso a diagnósticos básicos, uma força de trabalho treinada em nefrologia, acesso universal à atenção primária à saúde e terapias de substituição renal. Apontamos para a necessidade de fortalecer a infra-estrutura básica para serviços de cuidados renais para detecção e tratamento precoce de lesão renal aguda e doença renal crônica em todos os países e defender abordagens mais pragmáticas para o fornecimento de terapias de substituição renal. Alcançar a cobertura universal de saúde em todo o mundo até 2030 é um dos Objetivos de Desenvolvimento Sustentável da Organização Mundial da Saúde. Embora a cobertura universal de saúde não inclua todos os elementos do tratamento renal em todos os países, entender o que é viável e importante para um país ou região com foco na redução do impacto e das consequências da doença renal seria um passo importante para alcançar a equidade na saúde renal.

Background and Aims Transplantation is the first successful modality of renal replacement therapy (RRT) for irreversible chronic kidney disease (CKD; stage 5). Identifying additional factors associated with poor long-term prognosis after transplantation may provide clues regarding the pathophysiological mechanisms involved in allograft failure and identify high-risk patients who may benefit from additional monitoring or interventions. Successful kidney transplantation results in a substantial decrease in β2M levels, but a delayed decrease or increasing levels after transplantation may serve as a marker of acute rejection or inflammation. Several reports show that elevated sCD30 levels, pre and post transplantation are associated with a poor prognosis for long term kidney graft survival. These studies found higher CD30 levels in allograft recipients and a good predictor of impending acute rejection. The aim of the work is to study the prognostic outcomes of transplanted kidney using CD30 and β2-Microglobulin Method prospective study was conducted in nephrology unit –internal medicine department at Tanta and Kasr El Ainy university ,over 1 year.20 patients subjected to primary Tx.participated in this study.Cd30 and β2M.at day -1,2weeks and 3 months,with clinical follow up after 1 year to detect graft survival Results At day -1,level of cd30 was higher in rejection group than the other patient group.2 weeks post transplantation ,level of cd30 was higher in rejection group than the other patient group and at 3 monthes post transplantation level of cd30 was higher in rejection group than the other patient group,and these differences are statistically highly significant.(p values :0.003 ,0.005 and 0.002 respectively) Successful transplantation leads to significant decrease in serum cd30 at 2 weeks post tx.(P1 Successful transplantation leads to significant decrease in serum β2microglobulin at 2 weeks post tx.(P1 Conclusion pre transplantation high Cd30 and β2M is associated with poor outcome.failure of decrease of cd30 and β2M post Tx. also associated with poor outcome or infection. Successful transplantation leads to significant decrease in serum cd30 and β2M. which can be used as predictors of graft survival with better sensitivity and specificity than serum creatinin.

Living with chronic kidney disease (CKD) is associated with hardships for patients and their care-partners. Empowering patients and their care-partners, including family members or friends involved in their care, may help minimize burden and consequences of CKD-related symptoms to enable life participation. There is a need to broaden the focus on living well with kidney disease and re-engagement in life, including emphasis on patients being in control. The World Kidney Day (WKD) Joint Steering Committee has declared 2021 the year of "Living Well with Kidney Disease" in an effort to increase education and awareness on the important goal of patient empowerment and life participation. This calls for the development and implementation of validated patient-reported outcome measures to assess and address areas of life participation in routine care. It could be supported by regulatory agencies as a metric for quality care or to support labeling claims for medicines and devices. Funding agencies could establish targeted calls for research that address the priorities of patients. Patients with kidney disease and their care-partners should feel supported to live well through concerted efforts by kidney care communities including during pandemics. In the overall wellness program for kidney disease patients, the need for prevention should be reiterated. Early detection with prolonged course of wellness despite kidney disease, after effective secondary and tertiary prevention programs, should be promoted. WKD 2021 continues to call for increased awareness of the importance of preventive measures throughout populations, professionals, and policy makers, applicable to both developed and developing countries.Vivre avec l’insuffisance rénale chronique (IRC) représente un fardeau pour les patients et leurs partenaires soignants, dont leurs familles et amis. Une façon d’alléger ce fardeau et de réduire les conséquences des symptômes de l’IRC sur la participation à la vie serait de favoriser une plus grande autonomie des patients et de leurs partenaires soignants. Pour ce faire, l’accent mis sur le bien vivre avec la maladie et sur la participation à la vie doit être élargi en privilégiant notamment de mettre les patients en contrôle. Pour accroître l’éducation et la sensibilisation sur la responsabilisation des patients et, ultimement, encourager leur participation à la vie, le Comité directeur bipartite de la Journée Mondiale du Rein (JMR) a déclaré 2021 l’année du « bien vivre avec une maladie rénale ». Une stratégie qui nécessite l’élaboration et la mise en œuvre de mesures validées des résultats signalés par le patient afin d’aborder la participation à la vie dans les soins courants. Cette stratégie pourrait être appuyée par les organismes de réglementation comme mesure de qualité des soins ou pour appuyer les demandes relatives à l’étiquetage des médicaments et des dispositifs. Les organismes subventionnaires pourraient quant à eux établir des appels d’offres à objectifs de recherche définis afin de répondre aux priorités des patients. Les patients et leurs partenaires soignants devraient se sentir soutenus, même en contexte de pandémie, par des efforts concertés des communautés de soins en santé rénale. Dans le cadre du program de bien-être global destiné aux patients atteints d’une néphropathie, il convient de réitérer la prévention. À la suite de programs efficaces de prévention secondaire et tertiaire, il convient également de promouvoir une détection précoce avec une évolution prolongée du bien-être malgré une maladie rénale. La JMR 2021 continue d’appeler à une plus grande sensibilisation des populations, des professionnels et des décideurs quant à l’importance de mesures préventives applicables tant dans les pays développés que dans les pays en développement.

Hepatitis C virus (HCV) infection is an important cause of major morbidities including chronic liver disease, liver cancer, and acute kidney injury (AKI) as well as chronic kidney disease (CKD). HCV can affect kidney health; among CKD and AKI patients with HCV infection, the clinical outcomes are worse. The prevalence of HCV infection is exceptionally high among dialysis and kidney transplant patients throughout the globe. It is estimated that 5% to 25% or more of dialysis dependent patients are affected by chronic HCV, based on the region of the world. Almost half of all deaths in CKD patients, including HCV-infected patients, are due to cardiovascular disease, and HCV infected patients have higher mortality. Given the importance and impact of the HCV epidemic on CKD and global kidney health, and the status of Egypt as the nation with highest prevalence of HCV infection in the world along with its leading initiatives to eradicate HCV, the International Federation of Kidney Foundations (IFKF) convened a consensus conference in Cairo in December 2017. This article reflects the opinions and recommendations of the contributing experts and reiterates that with the current availability of highly effective and well tolerated pharmacotherapy; CKD patients should be given priority for treatment of HCV, as an important step towards the elimination of viral hepatitis as a public health problem by 2030 according to World Health Organization and IFKF. Every country should have an action plan with the goal to improve kidney health and CKD patient outcomes.

Given the uncertainty regarding the relationship between donor cells at microchimeric levels and its influence on graft function and clinical outcome, we explored the extent and importance of donor microchimerism in kidney transplantation. Twenty patients with chronic kidney disease who had received allografts from living donors were studied. We examined peripheral whole blood samples from the recipients one month after the transplant, applying mitochondrial DNA variant-specific polymerase chain reaction (PCR) to identify and quantify donor cells in relation to allograft function and survival during three years of follow-up. Higher quantities of donor-derived cell microchimerism in the peripheral blood correlated with better graft function in the early postoperative period at 1 month (R2 = .536, p = .001) and predicted improved graft function 1 year following the transplant (R2 = .430, p = .008). Furthermore, early post-transplant quantities of donor cell microchimerism were an important predictor of improved kidney function 3 years after transplantation (R2 = .397, p = .021). However, donor cell microchimerism failed to predict patient and graft survival after 3 years (odds ratio = 0.536, p = .860). Our findings suggest that donor cell microchimerism plays an immunoregulatory role in kidney transplantation and contributes to donor-specific immune hypo-responsiveness and graft acceptance.

Background Vitamin D has shown an immune-modulatory effect in different studies. Vitamin D stimulates Tregs and inhibits Th17 cells. The immune-modulatory role of vitamin D in chronic kidney disease (CKD) and renal transplant patients is unclear. We measured whether different serum levels of vitamin D were associated with an increased or decreased presence of lymphocyte subsets including Treg and Th17 cells in end-stage renal disease (ESRD) and renal transplant recipients. Methods Eighty-seven renal transplant recipients and 53 end-stage renal disease (ESRD) patients were enrolled in this study. The absolute counts of CD4 + and CD8 + T, CD16 + CD56 + NK, CD19 + B, CD4 + CD25 + CD127- Foxp3 + (Tregs), Helios + Tregs, CD38 + Tregs, and CD4 + CD17 + (Th17) cells were analyzed in peripheral blood in both patient groups. In addition, serum 25 (OH) D3, 1, 25 (OH)2 D3, IL-6, IL-17, IL-23, and TGF-β1 were measured. The association between lymphocyte subset counts and 1, 25 (OH)2 D3 or 25 (OH) D3 was studied, as was the association between serum IL-6, IL-17, IL-23, or TGF-β1 and 1,25 (OH)2 D3 or 25 (OH) D3. Results Serum 25 (OH) D3 and 1,25 (OH)2 D3 levels were not independently associated with peripheral CD4 + T, CD19 + B, CD16 + CD56 + NK, Treg, or Th17 cell counts. In contrast to serum 25 (OH) D3, serum1, 25 (OH)2 D3 was positively associated with CD8 + T cells counts in renal transplant recipients. Conclusion Our findings indicate low utility of serum 25 (OH) D3 and 1, 25 (OH)2 D3 levels in predicting a change in lymphocyte subset counts in ESRD and renal transplant patients.

Podocyte injury and subsequent excretion in urine play a crucial role in the pathogenesis and progression of diabetic nephropathy (DN). Quantification of messenger RNA expression in urinary sediment by real-time PCR is emerging as a noninvasive method of screening DN-associated biomarkers. We aimed to study the expression of podocyte-associated genes in urinary sediment and their relation to disease severity in type 2 diabetic Egyptian patients with diabetic nephropathy.ology: Sixty patients with type 2 diabetes mellitus were recruited in addition to twenty non diabetic healthy volunteers. Relative mRNA abundance of nephrin, podocalyxin, and podocin were quantified, and correlations between target mRNAs and clinical parameters were examined.The urinary mRNA levels of all genes studied were significantly higher in diabetics compared with controls (p 0.001), and mRNA levels increased with DN progression. Urinary mRNA levels of all target genes positively correlated with both UAE and HbAThe urinary mRNA profiles of nephrin, podocalyxin, and podocin were found to increase with the progression of DN, which suggested that quantification of podocyte-associated molecules will be useful biomarkers of DN.

La enfermedad renal es un problema global de salud pública; afecta a más de 750 millones de personas en el mundo. La carga de la enfermedad renal, su detección y tratamiento, varían sustancialmente en el planeta. Los países en desarrollo tienen una carga de enfermedad similar o incluso mayor que los desarrollados. En muchos escenarios, las tasas de enfermedad renal y la provision de su cuidado están definidas por factores socioeconómicos, culturales y políticos, ocasionando disparidades significativas aún en países desarrollados, en la prevención, pesquisa, acceso al cuidado y tratamiento de la enfermedad. El Día Mundial del Riñón 2019 ofrece una oportunidad para tomar conciencia de esta enfermedad. Esta editorial, resalta estas disparidades y enfatiza el rol de las políticas públicas y las estructuras organizacionales. Se destacan las oportunidades de entender las disparidades, para que puedan reducirse y canalizar esfuerzos para alcanzar una salud renal equitativa a nivel mundial.

Egypt, the single country with highest incidence of HCV infection in the world, has embarked on a government-sponsored mass treatment program using several combinations of DAAs. Recognizing the importance of extrahepatic manifestations, independently of the hepatic, a subcommittee was assigned to develop national guidelines for respective prioritizing indications and protocols. It evaluated the benefit of treating patients with different extrahepatic manifestations, and reviewed relevant clinical trials and guidelines concerning DAA combinations available in Egypt. The latter included Sofosbuvir plus either peg-interferon, Simeprevir, Ledipasvir or daclatasvir, and the Viekera family comprising paritaprevir/ritonavir + ombitasvir with (GT-1) or without (GT-4) Dasabuvir. Any of these protocols may be used with or without Ribavirin according to indication. A blueprint was subjected to peer debate in dedicated workshops in two national meetings and subsequently to an online professional review, eventually leading to a final report that was adopted by the health authorities. Seven compelling and 10 optional indications were identified for treating patients with predominantly extrahepatic manifestations. The former include kidney disease at different stages, cryoglobulinemic vasculitis and non-Hodgkin lymphoma. Selected treatment protocols, were encoded and their use was prioritized on the basis of evidence of efficacy and safety. We concluded that any of the studied protocols may be used, preferably with ribavirin, for 12-week treatment in all patients with extrahepatic manifestations without cirrhosis and with eGFR above 30 ml/min/1.73 sqm. Ribavirin should be included in protocols for treating patients with compensated cirrhosis. Daclatasvir-based protocols are recommended for decompensated cirrhosis, while the Viekera family is recommended in patients with eGFR

Mesenchymal stem cells (MSCs) are a group of multipotent cells found in cord blood, adipose tissue, bone marrow, and the stroma of various organs with a great potential for mesoderm-like cell differentiation. The aim of the present work was to study the paracrine effect of MSC transfusion in stage II and III chronic kidney disease, which is measured through the level of insulin growth factor-1 and vascular endothelial growth factor. Human bone marrow MSCs were isolated, expanded, and harvested after an average of 21-30 days not only morphologically, when the cells presented as a uniform spindle fibroblast and reached 70-80% confluence with a good cellular yield, but also through their immunophenotypic analysis, which showed positivity for CD29 and negativity for CD34. They were reinjected intravenously in 10 renal patients. To study the effect of such manipulation on the kidney, creatinine and creatinine clearance were measured at the day of injection (baseline), and the first and third month following injection. In addition, other modulators were measured during the first week of injection (day 0, 2, and 7) using enzyme-linked immunosorbent assay. To illustrate, for the first 3 months the creatinine and creatinine clearance reflected a significant renal improvement with an overall decrease of 14% and an increase of 23%, respectively. Although the third month's results may appear worse off than the first month's, they still were better than the baseline before transfusion. Therefore, such an improvement may be attributed to the growth factors released by the MSCs. In other words, both the vascular endothelial growth factor and insulin growth factor-1 showed an overall rise of 3 and 53%, respectively, in their level during the first week after transfusion. Therefore, MSCs transfused to the patients lead to the rise in such modulators, which in turn caused a significant improvement in renal functions. In conclusion, these findings may provide a novel therapy of regenerative medicine especially for chronic kidney disease where dialysis and renal transplantation are inevitable.
