Background and Aims: A potentially inappropriate medication (PIM) is a pharmaceutical agent that poses a greater risk of harm than potential benefit to elderly patients. This study aimed to detect PIMs and their risk factors in hospitalized elderly patients with kidney disease., Methods: This cross-sectional study assessed medication orders of elderly patients (≥65 years old) with kidney diseases admitted to the hospital. In the first 6 months, we retrospectively evaluated all medications to identify PIMs according to the 2019 Beers criteria. In the second phase, a clinical pharmacist prospectively evaluated all medications and suggested modifications as needed. Data were analyzed to determine risk factors for prescribing PIMs., Results: Based on our evaluation of 258 patients, we observed that the utilization of PIMs was prevalent among the study population. Of the total patients evaluated, 273 instances of PIM use were identified, with only 23.3% of patients not having any PIMs. Notably, proton pump inhibitors and benzodiazepines were the most frequently prescribed PIMs. The risk of experiencing a PIM was significantly amplified by a higher degree of polypharmacy, with odds approximately 2.68 times higher ( p  < 0.01). Several factors were found to be associated with an increased likelihood of having a PIM, including being male, undergoing hemodialysis, having chronic kidney disease or other comorbidities, and having an extended hospital stay. The second phase of study, in terms of addressing these issues, physicians adhered to 67.5% of the 120 recommendations made by pharmacists regarding the discontinuation of PIM usage., Conclusion: High prevalence of PIMs was detected in our study population. Preventing medication-associated harms in the elderly can reduce the financial burden imposed on healthcare systems. Therefore, routine evaluation of medications with clinical pharmacists and/or implementation of computerized medication decision support systems is recommended to prevent PIMs use., Competing Interests: The authors declare no conflict of interest., (© 2024 The Authors.

Objectives: The prevalence, types, severity, risk ratings, and common pairs of involved drugs, and the most important potential drug-drug interactions (pDDIs) in coronavirus disease 2019 (-COVID-19) deceased cases were evaluated., Materials and Methods: We reviewed the medical records of 157 confirmed COVID-19 deceased cases hospitalized in 27 province-wide hospitals. Patients' demographics and clinical data (including comorbidities, vital signs, length of in-hospital survival, electrocardiograms (ECGs), medications, and lab test results) were extracted. The online Lexi-interact database and Stockley's drug interactions reference were used to detect pDDIs retrospectively. The QTc interval and total Tisdale risk score were also calculated. Descriptive analysis, analysis of variance, Fisher exact test, and multivariate analysis were conducted for data analysis., Results: Of 157 study cases, 63% were male, had a mean age of 68 years, and 55.7% had one or more underlying diseases. All patients had polypharmacy, with 69.2% having ≥ 15 drugs/day. We detected 2,416 pDDIs in patients' records, of which 658 (27.2%) were interactions with COVID drugs. Lopinavir/ritonavir among -COVID drugs and fentanyl among non-COVID drugs were commonly involved in the interactions. pDDIs was significantly higher in the polypharmacy group of ≥ 15 medications (p < 0.001). A majority (83%) had received drug(s) with the QTc prolongation effect, of whom 67% had actual QTc prolongations in their ECGs. The regression analysis showed that by increasing 6.7% in polypharmacy, one day increase in-hospital survival can be expected. Moreover, an increase of 2.3% in white blood cells or 10.5% in serum potassium level decreased in-hospital survival by 1%., Conclusion: The findings underscored the importance of careful drug choice, especially in the hectic search for early treatments in pandemics of novel diseases. Close monitoring of patients' drug choice is warranted for reducing pDDIs and their adverse effects in any new disease outbreak.

Objectives: Widespread and prolonged therapy with ganciclovir (GCV) may result in the emergence of GCV-resistant mutations in human cytomegalovirus (HCMV) genome. The aim of this study was to detect the UL97 mutations associated with GCV resistance in kidney transplant recipients., Methods: Forty-nine kidney recipients with positive HCMV DNAemia, who received GCV therapy were included in this study. A 707 bp fragment of UL97 gene spanning codons (436 to 655) was amplified by nested PCR and sequenced., Results: Thirteen (26.5 %) out of 49 recipients contained mutations associated with amino acid changes. Two UL97 mutations related to GCV resistance were detected in 2 recipients (4 %), including alanine to valine (A594V) and proline to leucine (P521L). The D605E mutation was identified in 8 out of 49 (16.3 %) recipients. Silent mutations G598G, G503G, L553L, L634L, D456D and G579G were commonly observed., Conclusion: Our results indicate that mutations in the UL97 gene associated with GCV resistance may occur in 1 in 25 recipients treated with GCV. In addition, a higher mutation rate of D605E was detected in our recipients. This study provides the first evidence of the prevalence and pattern of GCV related mutations in Iranian Turkish recipients (Tab. 2, Fig. 1, Ref. 28).

Background: To improve chronic disease outcomes, self-management is an effective strategy. An electronic personal health record (ePHR) is a promising tool with the potential to support chronic patient's education, counseling, and self-management. Fitting ePHRs within the daily practices of chronic care providers and chronic patients requires user-centered design approaches. We aimed to understand users' needs and requirements in chronic kidney disease (CKD) care to consider in the design of an ePHR to facilitate its implementation, adoption, and use., Methods: A qualitative study was conducted in a major Iranian nephrology center including inpatient and outpatient settings in 2019. We conducted 28 semi-structured interviews with CKD patients, nurses, and adult nephrologists. To confirm or modify the requirements extracted from the interviews, a focus group was also held. Data were analyzed to extract especially those requirements that can facilitate implementation, adoption, and sustained use based on the PHR adoption model and the unified theory of acceptance and use of technology., Results: Participants requested an ePHR that provides access to up to date patient information, facilitates patient-provider communication, and increases awareness about patient individualized conditions. Participants expected a system that is able to cater to low patient e-health literacy and high provider workload. They requested the ePHR to include purposeful documentation of medical history, diagnostic and therapeutic procedures, tailored educational content, and scheduled care reminders. Messaging function, tailored educational content to individual patients' conditions, and controlled access to information were highly valued in order to facilitate its implementation, adoption, and use., Conclusions: We focused on the ePHR's content and functionalities in the face of facilitators and/or barriers envisioned for its adoption in nephrology care. Designers and implementers should value CKD patients' needs and requirements for self-management such as providing personalized education and counseling (on the basis of their condition and risk factors), health literacy, and disease progression levels. The socio-technical aspects of care also need further attention to facilitate ePHR's adoption., (© 2021. The Author(s).)

Surgical site infection (SSI) is one of the most common and debilitating complications of surgery. The risk of SSI rises if the patient has underlying health-related risk factors. This article reports on the complicated case of 61-year-old female with a history of obesity and diabetes. She was diagnosed with end-stage renal disease (ESRD) and had been receiving haemodialysis since 2012. She underwent a kidney transplant and developed a multidrug-resistant Pseudomonas aeruginosa SSI following surgery. She experienced delayed wound healing with a partially dehisced incision. Despite conventional wound care, there was no progress in wound healing. The authors combined sharp debridement, irrigation and antibiotic therapy with a silver-containing antimicrobial dressing for 1 month. Her SSI improved significantly and she returned to theatre for wound closure. The patient recovered well and was discharged from the hospital after suture removal. Wound care professionals can use combination therapies to manage SSIs effectively and reduce patient and healthcare costs.

Introduction: Serum levels of several pro-inflammatory cytokines are higher in hemodialysis patients compared to healthy people. Curcumin has been shown to be able to decrease cytokines levels in nonuremic subjects. Our goal was to evaluate the effect of nanocurcumin administration on cytokines levels in hemodialysis patients., Methods: The study was performed over a 3 months period on 54 hemodialysis patients who had been randomized to receive either nanocurcumin or placebo. Serum levels and gene expressions of tumor necrosis factor-alpha (TNF-α) and interleukin 6 (IL-6) were evaluated using enzyme-linked immunosorbent assay (ELISA) and real-time polymerase chain reaction (RT-PCR)., Findings: Serum levels of IL-6 and TNF-α were similar in the two groups at baseline but were lower after 12 weeks of treatment with nanocurcumin compared to placebo (P = 0.024 for IL-6 and 0.02 for TNF). In the group given nanocurcumin, serum levels of both cytokines decreased substantially (P < 0.001 for each), whereas they were unchanged in the group given placebo. Gene expression for each cytokine in peripheral blood mononuclear cells (PBMCs) was reduced at 12 weeks vs. baseline in the group given nanocurcumin, and changes in gene expression correlated with changes in serum level for each of the two cytokines., Discussion: The results indicate that nanocurcumin supplementation reduces both serum levels and gene expression of IL-6 and TNF-α in hemodialysis patients. The feasibility and potential clinical benefits of nanocurcumin treatment to reduce inflammation in hemodialysis patients warrant further study., (© 2021 International Society for Hemodialysis.)

Background: Drug-laboratory (lab) interactions (DLIs) are a common source of preventable medication errors. Clinical decision support systems (CDSSs) are promising tools to decrease such errors by improving prescription quality in terms of lab values. However, alert fatigue counteracts their impact. We aimed to develop a novel user-friendly, evidence-based, clinical context-aware CDSS to alert nephrologists about DLIs clinically important lab values in prescriptions of kidney recipients., Methods: For the most frequently prescribed medications identified by a prospective cross-sectional study in a kidney transplant clinic, DLI-rules were extracted using main pharmacology references and clinical inputs from clinicians. A CDSS was then developed linking a computerized prescription system and lab records. The system performance was tested using data of both fictitious and real patients. The "Questionnaire for User Interface Satisfaction" was used to measure user satisfaction of the human-computer interface., Results: Among 27 study medications, 17 needed adjustments regarding renal function, 15 required considerations based on hepatic function, 8 had drug-pregnancy interactions, and 13 required baselines or follow-up lab monitoring. Using IF & THEN rules and the contents of associated alert, a DLI-alerting CDSS was designed. To avoid alert fatigue, the alert appearance was considered as interruptive only when medications with serious risks were contraindicated or needed to be discontinued or adjusted. Other alerts appeared in a non-interruptive mode with visual clues on the prescription window for easy, intuitive notice. When the system was used for real 100 patients, it correctly detected 260 DLIs and displayed 249 monitoring, seven hepatic, four pregnancy, and none renal alerts. The system delivered patient-specific recommendations based on individual lab values in real-time. Clinicians were highly satisfied with the usability of the system., Conclusions: To our knowledge, this is the first study of a comprehensive DLI-CDSS for kidney transplant care. By alerting on considerations in renal and hepatic dysfunctions, maternal and fetal toxicity, or required lab monitoring, this system can potentially improve medication safety in kidney recipients. Our experience provides a strong foundation for designing specialized systems to promote individualized transplant follow-up care.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is a delayed-onset renal disorder that results from a mutation in the PKD1 or PKD2 genes. Autosomal dominant polycystic kidney disease results in end-stage renal disease due to renal cystic dysplasia. The aim of this study was to evaluate, by exon sequencing, the disease-causing variants of PKD2 (exons 4, 6, and 8) in Iranian ADPKD patients., Methods: Genomic DNA was extracted from 3-5 ml of peripheral blood by the salting-out method. PKD2 exons 4, 6, and 8 were PCR-amplified and sequenced., Results: Three disease-causing PKD2 variants were identified; all three were missense mutations in exon 4. The mutations were AGC → ACC (c.893G>C, cDNA.959G>C, S298T), TAC → TTC (c.1043A>T, cDNA.1109 A>T, Y348F), and GAA → GAT (c.1059A>T, cDNA.1125 A>T, E353D. These novel pathogenic variants may cause loss of the normal protein function., Conclusion: Our results suggest that AGC → ACC (c.893G>C, cDNA.959G>C, S298T), TAC → TTC (c.1043A>T, cDNA.1109 A>T, Y348F), and GAA → GAT (c.1059A>T, cDNA.1125 A>T, E353D variants are common in Iranian ADPKD patients. These mutations modify the transmembrane domain and likely influence PC2 function.

Background: Autosomal dominant polycystic kidney disease (ADPKD) is a highly prevalent life-threatening monogenic disorder with high morbidity and mortality. Roughly 1:400-1000 individuals are affected with this disease worldwide. The development of ADPKD is largely attributed to mutations in the polycystic kidney disease (PKD) 1 and PKD2 genes. However, the pathogenicity of the different polymorphisms in PDK1 in the development of ADPKD remains unclear. The aim of this study was to further elucidate the role of the polymorphisms in exon 25 of the PDK1 gene in relation to the pathogenesis of ADPKD in Iranian patients., Methods: The genomic DNA of 36 Iranian patients with ADPKD was isolated using the standard salting out method. The PCR products were directly sequenced and analyzed., Results: The frequencies of CAG>GAG, ATG>GTG, GTC>GTA, and GTG>ATG polymorphisms in exon 25 of the PKD1 gene were 34 (94.44%), 33 (91.67%), 26 (72.22%), and 5 (13.89%), respectively. The most frequent polymorphism associated with ADPKD was the homozygous CAG→GAG which causes an amino acid change of Q[Gln] to E[Glu] at codon 3005., Conclusion: Our data suggests that there is potentially a common polymorphism of PDK1 among the Iranian population with ADPKD. This may aid in the diagnosis and genetic screening of at-risk patients for ADPKD.

Background: The effectiveness of the clinical decision support systems (CDSSs) is hampered by frequent workflow interruptions and alert fatigue because of alerts with little or no clinical relevance. In this paper, we reported a methodology through which we applied knowledge from the clinical context and the international recommendations to develop a potential drug-drug interaction (pDDI) CDSS in the field of kidney transplantation., Methods: Prescriptions of five nephrologists were prospectively recorded through non-participatory observations for two months. The Medscape multi-drug interaction checker tool was used to detect pDDIs. Alongside the Stockley's drug interactions reference, our clinicians were consulted with respect to the clinical relevance of detected pDDIs. We performed semi-structured interviews with five nephrologists and one informant nurse. Our clinically relevant pDDIs were checked with the Dutch "G-Standard". A multidisciplinary team decided the design characteristics of pDDI-alerts in a CDSS considering the international recommendations and the inputs from our clinical context. Finally, the performance of the CDSS in detecting DDIs was evaluated iteratively by a multidisciplinary research team., Results: Medication data of 595 patients with 788 visits were collected and analyzed. Fifty-two types of interactions were most common, comprising 90% of all pDDIs. Among them 33 interactions (comprising 77% of all pDDIs) were rated as clinically relevant and were included in the CDSS's knowledge-base. Of these pDDIs, 73% were recognized as either pseudoduplication of drugs or not a pDDI when checked with the Dutch G-standard. Thirty-three alerts were developed and physicians were allowed to customize the appearance of pDDI-alerts based on a proposed algorithm., Conclusion: Clinical practice contexts should be studied to understand the complexities of clinical work and to learn the type, severity and frequency of pDDIs. In order to make the alerts more effective, clinicians' points of view concerning the clinical relevance of pDDIs are critical. Moreover, flexibility should be built into a pDDI-CDSS to allow clinicians to customize the appearance of pDDI-alerts based on their clinical context., (Copyright © 2019 Elsevier B.V.

Non-healing diabetic foot ulcers are a common and costly complication of type 2 diabetes and can result in lower extremity amputation. This case study concerns a 51-year-old man with a 17-year history of uncontrolled type 2 diabetes. He had developed a deep ulcer to the calcaneus of his left foot, which was 12x7 cm in size and infected with multi-drug-resistant Staphylococcus aureus . He was admitted to hospital for the non-healing diabetic foot ulcer and uncontrollable fever and was a candidate for amputation. He was treated with wound irrigation and debridement as well as negative-pressure wound therapy and antibiotic treatment. This strategy was effective and the wound size reduced progressively. The patient recovered well. Medical and wound care teams who deal with non-healing diabetic foot ulcers can benefit from a strategy of combination therapy.

Aspergillus species (sp.) that causes opportunistic infections have been increasingly found in human mainly immunosuppressive patients around the world every year. The main objective was to use a rapid and cheap molecular method for monitoring Aspergillus infections and epidemiological approaches. In order to identity Aspergilli species (spp.), a number of molecular methods including restriction fragment length polymorphism (RFLP) have been employed in accordance with ribosomal RNA amplification. The focus of this study - a group of hospitalized patients with clinical and subclinical signs of infection. All of the collected clinical specimens were transported to the medical mycology lab and examined for Aspergillus identification. The environmental specimens were collected from air and surfaces inspected for the Aspergillus within the hospital sources. At first, growth characteristics and microscopic features on mycological media for the identification of Aspergillus sp. were performed. For the confirmation of Aspergillus isolates which similarly found in clinical and environmental sources, molecular method polymerase chain reaction/restriction fragment length polymorphism was carried out. From the mentioned specimens, 102 fungal isolates included Candida spp., Aspergillus spp. and other fungi. Aspergillus flavus (47%), Aspergillus fumigatus (29.4%) and Aspergillus niger (23.5%) all were found as the most common clinical isolates. In addition, Aspergillus isolates from environmental were Aspergillus niger (43.7%), Aspergillus flavus (41.7%), Aspergillus fumigatus (14.6%). Therefore, polymerase chain reaction-restriction fragment length polymorphism with a single restriction enzyme can be very useful in the identification of Aspergillus spp., because of its facility in use, speed, robust, and high sensitivity of diagnosis.

Candidiasis is a major challenge among renal transplant recipients (RTRs) worldwide and is associated with high morbidity and mortality rates. Fluconazole is the most commonly used agent for Candida infections. However, frequent relapse and treatment failure are still reported among patients affected with this infection. In the present study, Candida species obtained from RTRs were characterized based on conventional and molecular assays. Furthermore, the antifungal susceptibility profiles of these species were determined. This study was conducted on a total of 126 RTRs within 2012-2016. The patients were categorized according to the referenced diagnostic criteria. The identification of Candida species was accomplished based on conventional examination, assimilation profile test, and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. The minimum inhibitory concentrations (MICs) of amphotericin B, fluconazole, itraconazole, voriconazole, posaconazole, and caspofungin were determined based on the guidelines of Clinical and Laboratory Standards Institute. The patients with Candida infection were diagnosed with urinary tract candidiasis (n = 17), peritonitis (n = 8), intra-abdominal candidiasis (n = 6), candidemia (n = 4), hepatosplenic candidiasis (n = 3), and Candida pneumonia (n = 3). A total of 41 Candida isolates, including C. albicans (n = 18), C. famata (n = 8), C. kefyr (n = 4), C. tropicalis (n = 4), C. parapsilosis (n = 3), C. glabrata (n = 2), and C. lusitaniae (n = 2), were isolated from 32.5% (41/126) renal transplant recipients. Fluconazole-resistance was observed in seven isolates, entailing C. albicans (n = 6) and C. tropicalis (n = 1). Fluconazole MIC for C. lusitaniae isolates was above the epidemiologic cut-off value (4-16 μg/ml). Furthermore, MIC range values of fluconazole against C. famata and C. kefyr were obtained as 4-32 μg/ml and 4-8 μg/ml, respectively. Posaconazole exhibited potent activity against Candida isolates, followed by caspofungin. The identification of Candida species, together with susceptibility testing, provides important data about the geographic trends of the fluconazole-resistance profiles of Candida species. It is necessary to maintain a consistent method for the implementation of early diagnosis and adoption of treatment regimen., (Copyright © 2018 Elsevier Ltd. All rights reserved.)

Objective: Lupus nephritis is one of the most serious and common complications of systemic lupus erythematosus. It has an unpredictable course, and the type, severity, and activity of renal lesions cannot be assessed only by clinical and laboratory findings. The aim of the present study was to determine the relationship between the expression of CD34 and the histopathological findings of lupus nephritis., Methods: A total of 73 renal biopsy samples of patients with a diagnosis of lupus nephritis were examined for CD34 expression by immunohistochemistry. Samples without staining were considered as 0, mild staining as 1+, moderate as 2+, and strong staining as 3+. The relationship between CD34 expression and histopathological and clinical data (including activity index, chronicity index, lupus nephritis class, age, sex, blood pressure, complete blood count, renal function tests, and serological findings) was analyzed., Results: The mean age of the patients was 29.3±11.3 years. CD34 was expressed in all of the cases but with different intensities. There was a significant relationship between the expression of CD34 and the activity index, as a strong expression was seen in lower activity indices (p<0.001). CD34 expression was correlated with patients' white blood cell (WBC) count and systolic blood pressure (SBP). Patients with strong (score 3) CD34 expression had higher SBPs and lower WBC counts (p=0.03 and 0.04, respectively)., Conclusion: A strong interstitial expression of CD34 was observed in lower activity indices. It seems that CD34 expression could play a protective role in lupus nephritis and could reduce renal activity.

Renal cell carcinoma (RCC) comprises 2%-3% of all visceral and 80%-85% of all adult kidney malignancies. Nephrectomy is the treatment of choice for renal tumors. The accurate pathological evaluation of nonneoplastic renal parenchyma in nephrectomy specimens is important for subsequent management. Eighty-two patients with RCC who underwent surgery at Imam Khomeini Hospital, Urmia, Iran, from April 2006 to February 2015 were studied. Paraffin blocks of the hospital archives were stained by hematoxylin and eosin (H and E) and periodic acid-Schiff staining. Microscopic examination was performed on nontumoral portions that were in the farthest possible distance from the tumor. Out of total 82 cases, 24 (29.3%) had normal renal parenchyma and 58 (70.7%) had pathological changes in renal parenchyma. The most frequent pathological findings were vascular sclerosis with parenchymal scarring and pyelonephritis. Other findings include focal and diffuse mesangial hypercellularity, eight; focal segmental glome-rulonephritis, five; membranoproliferative glomerulonephritis, three; and membranous glome-rulonephritis, two. Parenchymal scarring and vascular change included 36% of clear cell type, 41% of papillary type, and 53.8% of chromophobe type. Although there is not any statistical relation between the gender of patients and pathological findings, there was an obvious correlation between age and pathological findings. Before the age of 55 years, vascular sclerosis with parenchymal scarring and glomerular diseases and then chronic pyelonephritis are more prevalent.Evaluation of pathological changes in nonneo-plastic renal parenchyma is an essential step in recognizing patients at risk of accelerated functional failure of the single remaining kidney, particularly in patients with a background of chronic vascular injury associated with diabetes or hypertension., Competing Interests: None declared

Cytomegalovirus (CMV) is one of the most important infections in renal transplant recipients. Kidney transplant is the last hope for the patients with end stage renal diseases. Cytomegalovirus infection can threaten patients and graft survival after transplantation. Four hundred and thirty-four renal transplant recipients contributed to this study. PCR and RFLP analyses were performed in order to determine CMV viremia and its genotypes. CMV viremia was detected in 68 (15.9%) recipients. The mean post-transplantation time in our recipients was 50 months, ranging from 1 to 354 months. Viremia was detected in 31.2%, 30.7%, 17.5%, 10.2%, and 6.4% of the recipients in 0-3, 4-6, 7-12, 13-24, and more than 24 months post-transplantation, respectively. The distribution of gB1, gB2, gB3, and gB4 genotypes was detected as 26.5%, 20.5%, 17.6%, and 5.9%, respectively. Mixed genotype infection was observed in 29.4% of the recipients. Incidence of viremia was higher in the first 6 months after the transplantation compared with the later stages. Moreover, CMV gB1 and mixed genotype infection were more common in our recipients. J.

Introduction: Receiving a kidney transplant from donors with multiple renal arteries (MRAs) is suggested to be associated with higher risk of vascular and urologic complications and poor allograft outcomes compared to the donors with single renal artery (SRA). We evaluated survival rates in the recipients from donors with MRAs compared to those from donors with SRA., Materials and Methods: In a retrospective study on 115 kidney allograft recipients, demographic characteristics and the outcomes of kidney transplantation were compared between the recipients from donors with MRAs compared to those from donors with SRA. These included acute tubular necrosis, acute allograft rejection, hypertension, vascular complications, urologic complications, kidney function indicators, and allograft survival at 1 year., Results: There was no significant difference in the recipients' age, sex distribution, and weight, donors' age, donor-recipient familial relation, urologic complications, and duration of hospitalization between the two groups. However, MRA was significantly associated with a higher likelihood of right-side kidney donation, longer warm and cold ischemia times, and lower glomerular filtration rate and higher serum creatinine concentrations at discharge and 12 months after transplantation, as compared to SRA transplants. No significant difference was seen in late complications including hypertension and renal artery stenosis. One-year graft survival was slightly poorer in the MRA group than the SRA group., Conclusions: Our results demonstrate that kidney allografts with MRAs are associated with risks but have acceptable outcomes during the 1st year after transplantation, as compared to SRA kidney allografts.

Kaposi's Sarcomas (KS) have been associated with many conditions and also known as a typical complication of immunosuppression. It should be considered as an important differential diagnosis in skin lesions of patients after solid organ transplantation. This is a report of a 61-year-old man, who presented with disseminated KS and a history of renal transplantation. We suggest systemic evaluation and visceral assessment in patients with Cutaneous KS.

Introduction: In dialysis centers both nephrologists and nurses are faced with the challenge of ensuring reliable and efficient care accordance with the clinical guideline. Hemodialysis adequacy monitoring information system therefore enable the automation of tasks, which ultimately allows doctors and nursing staff more time to dedicate to the individual treatment of patients. Development of the information systems in healthcare has made the use of the Minimum data set inevitable. The purpose of this study was determined MDS and capabilities required in hemodialysis adequacy monitoring information system., Method and Materials: This is a cross-sectional survey conducted with participation of 320 nephrology specialists in 2015. Data were collected using an electronic questionnaire which was estimated as both reliable and valid. The data were analyzed by SPSS software descriptive statistics and analytical statistics., Results: Overall 42 data elements were determined as final set in 4 major categories (patient demographics, medical history, treatment plan and hemodialysis adequacy). The most capabilities required of hemodialysis information system were related to calculate of dialysis adequacy Index (4.80), advice optimal dose of dialysis for each patient (4.63), Easy access to information system without restrictions of time and place (4.61), providing alerts when dialysis adequacy index below the standard (4.55) and Interchange to other information systems in hospitals (4.46) respectively., Conclusion: In design and implementation of information systems focus on MDS and identification IS capabilities based on the users' needs, due to the wide participation users and also the success of the information system. Therefore it is necessary that MDS evaluated carefully with regard to the intended uses of the data. Also information systems based on capabilities the ability to meet the needs of their users.

After renal transplantation approximately forty percent of patients with membranous glomerolunephritis (MGN) had a recurrence, most commonly during the first year.We present two cases with recurrent MGN after kidney transplantation who successfully treated with ritoximab.

Arteriovenous fistula (AVF) is the best permanent access for hemodialysis. Swelling and pain due to thrombosis and infection is common at fistula site. Angiosarcoma is one of rare but important differential diagnosis of these signs. We present a patient on CAPD with angiosarcoma at AVF.
