The study aimed to scrutinize the risk factors for foot ulceration in adult patients with diabetes with end-stage renal disease on hemodialysis in Dakahlia Governorate central hemodialysis units. Patients and methods This cross-sectional study included all diabetic patients under CHD aged more than or equal to 18 years (n=98), recruited over 7 months from the largest seven central hemodialysis units in Dakahlia Governorate, Egypt. Data collection consisted of a participant interview, medical record review, and noninvasive comprehensive foot examination. The assessment included peripheral neuropathy, peripheral arterial disease, other foot pathologies, footwear, and foot health care behavior. Results The study included 57 males and 41 females. The median duration of diabetes was 15 (2–33) years. Overall, 61 (62.2%) patients were on insulin therapy. The median duration of hemodialysis was 3 years. Insensate neuropathy and peripheral arterial disease were detected in 65.3 and 15.3% of patients, respectively. The prevalence of foot deformities was 18.36%. Plantar calluses and dry skin were diagnosed in 27.6 and 62.2% of patients, respectively. A total of two (2.04%) patients had active foot ulcers and nine (9.18%) patients had ulcers in remission; therefore, the overall diabetic foot ulceration prevalence was 11.22%. In addition, 10 (10.2%) patients had previous minor amputations, with no reported major amputations. Overall, 95.92% had poor foot health care behaviors, and 81.63% were using inappropriate footwear. None of the included patients previously used custom-made insoles. Conclusions The key finding of this article suggests a high prevalence of risk factors for foot ulceration among diabetic patients receiving hemodialysis. Diabetic foot screening should be included in the management strategy of those on CHD.","PeriodicalId":285751,"journal":{"name":"Journal of The Egyptian Society of Nephrology and Transplantation","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-08-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116667804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We aimed to determine the frequency and association of chemokine receptor 2 (CCR2)-V64I polymorphism in patients with ESRD. Patients and methods A total of 35 patients attending the hemodialysis unit and 21 healthy controls were recruited in this study. The PCR-restriction fragment length polymorphism technique was used to assess genotype frequencies of CCR2-V64I. Results The frequency of genotypes GG, AG, and AA in patient group was 65.7, 25.7, and 8.6%, respectively, in comparison with 81.0, 14.3, and 4.8%, respectively, in the control group. Therefore, the patient group showed higher frequency of AG and AA genotypes and a lower frequency of GG genotype than the control group but this difference was not significant. The frequencies of A and G alleles did not show a significant difference between the two groups. The frequencies of G and A alleles were 78.6 and 21.4%, respectively, in the patient group in comparison with 88.1 and 11.9%, respectively, in the controls. Patients carrying the genotypes AA and G/A showed rapid progression to ESRD than those with genotype G/G. No significant association was found between the occurrence of polymorphism and the presence of hypertension or diabetes mellitus. Conclusion The CCR2-V64I gene polymorphism may play a role in the pathogenesis and severity of ESRD in Egyptian patients. To uncover this role, further analyses should be carried out on larger population-based studies.","PeriodicalId":285751,"journal":{"name":"Journal of The Egyptian Society of Nephrology and Transplantation","volume":"153 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132313531","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Combination of PCAR with other glomerulopathies has not been reported before. Here, we report a case of late-onset PCAR associated with membranous glomerulonephritis (MGN) diagnosed at an early stage (2 years after transplantation). A 58-year-old male patient had end-stage kidney disease secondary to diabetic nephropathy and he was maintained on hemodialysis for 2 years until he underwent overseas living kidney transplantation. He presented to our center in Kuwait on the sixth day postoperatively, with stable renal function. He was maintained on steroid, cyclosporine, and mycophenolate mofetil. Two years after transplant, he developed picture of nephritic syndrome. His graft biopsy showed plasma cell-rich interstitial infiltrate associated with mild edema and focal tubulitis (PCACR) in addition to MGN. Further immunohistochemistry tests revealed both B-cell and T-cell markers (CD20 and CD3) were expressed in the lymphoplasmacytic infiltrate with predominant T lymphocytes. The possibility of multiple myeloma was ruled out. He received pulse steroid 1 g od for 3 days. His maintenance immunosuppression was intensified to tacrolimus-based regimen. Cluster differentiated lymphocyte count showed high CD-19 cells; therefore, we gave him a single dose of rituximab (375 mg/m2). Follow-up graft biopsy (1 month later) revealed MGN with complete resolution of plasma cells. His proteinuria started to improve after 4 months of management. He is enjoying stable graft function with controlled diabetes mellitus. PCAR is a treatable form of acute cellular rejection, and its combination with MGN will need special care with specific CD20 ablation therapy.","PeriodicalId":285751,"journal":{"name":"Journal of The Egyptian Society of Nephrology and Transplantation","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131607605","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

BKV infection, an early complication of renal transplant, often presents within the first year after transplantation. It presents as an asymptomatic gradual rise in creatinine with tubulointerstitial nephritis that mimics acute rejection and poses a diagnostic and therapeutic dilemma. More frequent diagnosis of BKV infection over the past 2 decades is a consequence of more potent immunosuppression (aimed to prevent acute rejection episodes and, thereby, improving allograft survival). Untreated BKV infections cause renal allograft dysfunction and subsequently allograft loss. A routine screening protocol for early recognition of asymptomatic BKV infection has been reported to result in better allograft outcomes. This review is aimed to discuss the most recent evidence addressing the virology, pathogenesis, clinical features, diagnostic tools, screening protocols, treatment strategy, and short-term and long-term renal allograft survival concerning BKV infection.","PeriodicalId":285751,"journal":{"name":"Journal of The Egyptian Society of Nephrology and Transplantation","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133004071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The etiology of sleep disorders in these patients is known to be multifactorial. However, the role of hydration status in sleep disorders in HD patients is not well studied. Therefore, our aim was to study the effect of predialysis fluid overload on sleep quality in HD patients. Patients and methods This cross-sectional study included 100 prevalent HD patients from the HD unit of El Sahel Teaching Hospital. Fluid status and fluid compartments [total body water), extracellular water (ECW),and overhydration (OH) index] were analyzed by a portable whole-body bioimpedance spectroscopy (body composition monitor) before a mid-week dialysis session. OH was defined as OH/ECW% more than or equal to 15%. HD patients were then classified into two groups: group 1 (normohydrated) and group 2 (overhydrated) according to the relative OH index (OH/ECW%). Sleep quality was assessed in all patients by the Pittsburgh Sleep Quality Index (PSQI) questionnaire. Patients with concurrent diagnosis of either obstructive sleep apnea or psychiatric disorder and patients on any medications that affect the sleep pattern were excluded. Results Our study included 100 HD patients (49 male, 51 female; mean age, 49.3 ± 11); 42 (42%) patients had OH (i.e. group 2). Poor sleep quality (defined as PSQI score ≥5) was reported in 57% (n=57) of HD patients included in our study. Poor sleep quality was significantly higher in the HD patients with OH (group 2).
