Therapeutic plasma exchange is a procedure in which plasma is removed and replaced with another fluid to correct blood abnormalities. There is growing evidence of its benefit in certain clinical conditions, including thrombotic thrombocytopenic purpura, hematological diseases, and immune-mediated neurological disorders. Therapeutic plasma exchange prescription includes the choice of technique (centrifugation or membrane filtration) and the choice of vascular access, as well as the total plasma volume to be exchanged, the type of replacement fluid, the number and frequency of sessions, and the method of anticoagulation. These patients may be critically ill and undergo this technique in an intensive care unit, where the intensivist manages the procedure independently or in collaboration with other specialists. We aim to make an easy-to-follow general prescription of this procedure, by offering a practical revision that empowers physicians, such as non-autonomous intensivists, to autonomously prescribe and manage this procedure, reducing delays in initiating treatment and addressing complications.

Introduction: Temporary non-tunneled catheters are necessary in patients with chronic kidney disease requiring acute hemodialysis care, and complications associated with these catheters, such as infection and thrombosis, represent the most important sources of morbidity. There are no studies available that suggest the optimum duration of their use before catheter exchange or removal. This study aimed to explore the duration of temporary catheter insertion before the occurrence of catheter-related infection and mechanical complications in hemodialysis patients. Methods: Systematic searches were conducted according to the PRISMA 2020 guidelines on four databases up to 1 May 2025 (PROSPERO: CRD420251069657). The study outcome was the occurrence time to catheter-related infection and mechanical complications (thrombosis, obstruction, and kinking, causing dysfunction, failure, or insufficient blood flow) in days, pooled using a single-arm meta-analysis. Mean and 95% confidence interval (CI) were used as the summary statistics. Results: Nine studies involving 1448 participants undergoing hemodialysis using temporary catheters were included. Incidence of infection ranged from 0.7 to 13.58 per 1000 catheter-days. The most common bacterium identified was Staphylococcus aureus and Pseudomonas aeruginosa. The pooled mean time to catheter-related infection from 298 catheters was 15.98 days (95% CI 10.47–21.50; I² = 97.73%). We also found that the pooled mean time to mechanical complications from 507 catheters was 6.69 days (95% CI 2.49–10.90; I² = 98.03%). Conclusion: Among patients who developed complications, the mean time from temporary catheter insertion was approximately two weeks to the occurrence of catheter-related infection and one week to mechanical complications. Our finding was consistent with the recommendation of the KDOQI guideline, which suggests limiting catheter duration to typically less than two weeks. Full article

Background: Preserving arm veins is important for arteriovenous fistula (AVF) creation in patients with advanced chronic kidney disease (CKD), as mature AVF is the preferred hemodialysis access. Midline catheters introduced into AVF candidate veins may cause thrombosis, hindering AVF formation. This study aims to determine ultrasonographic rates of midline-associated upper extremity deep venous thrombosis (UE-DVT) or superficial venous thrombosis (SVT) in patients with advanced CKD. Methods: We conducted a prospective study involving subjects with advanced CKD, who had a point-of-care ultrasound-guided midline placed in an arm vein. Within 35 days of midline insertion, participants underwent routine bilateral UE venous duplex ultrasound. The primary outcome was a composite occurrence of UE-DVT/SVT ipsilateral to the midline. Comparative analyses were performed based on patient demographics and device-specific variables. Results: 49 subjects with advanced CKD received midlines. The median midline catheter dwell time was <6 days for 15/49 patients (30.6%). The primary outcome occurred in 15/49 patients (30.6%), mostly asymptomatic thrombosis. No significant associations were found between outcomes and patient or device characteristics. Conclusions: Our study identified frequent use of midlines with short dwell times in subjects with advanced CKD which calls into question proper device selection. In this cohort, midline-associated arm clots were frequent. Full article

Lithium is the most reliable mood stabilizer available for the treatment of bipolar disorder. However, its use is limited by multiple concerns, including acute toxicity. Lithium levels have frequently been key to decisions regarding initiation of dialysis. Following the methodological principles of the Scale for the Assessment of Narrative Review Articles (SANRA), comprehensive searches were conducted across the following databases: PubMed, Embase, Web of Science, and Cochrane Library, without limitations on publication period. In an effort to standardize and objectify the decision to use dialysis, current treatment recommendations discuss clinical presentation but ultimately rely on measured serum lithium levels. Decision making can be improved if it takes into account whether lithium toxicity occurred slowly (which is equivalent to chronic toxicity, so that clinical signs of toxicity exceed expectations of measured lithium levels) or quickly (in which measured lithium levels exceed observed clinical severity). We propose that clinicians consider these factors and suggest that involving a broader interdisciplinary team, including psychiatry, in the decision-making process could enhance outcomes.

Background: Patients undergoing maintenance hemodialysis (HD) have a high risk of developing cardiovascular diseases due to calcification of the heart valves and coronary arteries, which results in a high mortality rate. In particular, aortic stenosis (AS) is an independent risk factor for heart failure-related mortality in patients undergoing HD. Recently, the analysis of digitized heart sounds using artificial intelligence (AI) has promoted the automation of cardiac disease detection and technological advances in diagnostic algorithms. Methods: We retrospectively investigated the 203 consecutive patients receiving HD who had undergone visualized phonocardiography using a regulatory-approved medical device (Japan) between January and May 2025 to detect AS. The usefulness of this phonocardiogram device, which utilizes acoustic analysis and an AI-based automatic diagnostic algorithm named the “Super Stethoscope”, was evaluated for the screening of AS in patients undergoing HD based on comparisons with findings obtained from echocardiography. Results: The results showed a significant correlation between the severity of systolic murmurs determined by the AI-based approach and the peak aortic jet velocity measured in 19 patients diagnosed with AS using transthoracic echocardiography (r = 0.578, p < 0.05). Additionally, for the AI-based diagnosis of AS based on systolic murmurs, the sensitivity and specificity in detecting moderate or severe AS were 0.90 and 0.70, respectively, among the patients undergoing HD. Conclusions: The AI-based diagnostic approach using the ECG-gated phonocardiogram “Super Stethoscope” could be a promising tool for AS screening. Transthoracic echocardiography is recommended in cases classified as grade B or higher by AI-based assessment. Full article

Background: Matrix metalloproteinases (MMPs) and their inhibitors, tissue inhibitors of metalloproteinases (TIMPs), regulate the extracellular matrix. This study examined messenger RNA transcripts of TIMP2 before and after kidney transplantation. Methods: Transcripts were measured in peripheral blood mononuclear cells from 105 kidney transplant recipients, including AB0-incompatible, AB0-compatible, and deceased donor transplantation patients. Quantitative real-time polymerase chain reaction was utilized. Results: Kidney transplant recipients (72 male; 33 female) were a median of 55 (44–63) years old. The median (interquartile range) of pretransplant TIMP2 transcripts was 0.68 (0.50–0.87) in kidney transplant recipients. In total, 9 out of 72 patients (13%) showed delayed graft function, i.e., need for dialysis within 1 week after transplantation. Preoperative TIMP2 transcripts were significantly lower in kidney transplant recipients who experienced delayed graft function compared to patients with immediate graft function (0.40 (0.32–0.62) vs. 0.68 (0.56–0.87); p = 0.01). There was no association between TIMP2 transcripts and age or gender. TIMP2 median transcripts were 0.73 (0.58–0.88) on the first postoperative day. TIMP2 transcripts were similar on the first postoperative day in patients with delayed graft function and immediate graft function. Conclusions: Preoperative TIMP2 transcripts were lower in patients with delayed allograft function. Future investigations are needed to establish the role of TIMP2 transcripts in transplant pathophysiology. Full article

Membranous nephropathy (MN) is an immune complex-mediated glomerular disease defined by sub-epithelial deposits that trigger complement activation and podocyte injury. Its pathogenesis reflects loss of immune tolerance and may present as a kidney-limited autoimmune process or in association with underlying conditions (e.g., malignancy, infection, drugs, or systemic autoimmunity). Current diagnostic work-up integrates circulating antibodies—most commonly anti–phospholipase A2 receptor 1 (PLA2R1)—and kidney biopsy, which remains essential in PLA2R1-negative or atypical presentations and for antigen confirmation when serology is negative. In PLA2R1-negative MN, an expanding list of antigens is being recognized, potentially refining phenotyping and risk assessment; however, dedicated studies remain limited, and the clinical weight of many newly described antigens likely requires further validation before supporting an antigen-based classification. Uneven access to advanced diagnostics particularly affects PLA2R1-negative cases, underscoring the need for centralized testing and the development of reliable non-invasive biomarkers. Treatment has advanced with rituximab and other targeted therapies, but resistant and relapsing cases remain challenging, and the evidence base for PLA2R1-negative forms is comparatively limited. This review summarizes recent diagnostic and therapeutic advances, focusing on PLA2R1-negative MN. Full article

Background: Gastrointestinal (GI) symptoms are highly prevalent in people receiving dialysis and contribute to malnutrition and poor quality of life. We examined the prevalence and severity of GI symptoms in Jordanian adults with end-stage kidney disease (ESKD) treated with hemodialysis (HD) or peritoneal dialysis (PD). Methods: In this cross-sectional study, consecutive adults with ESKD receiving maintenance HD at Al-Karak Teaching Hospital or PD at Al-Basheer Hospital were interviewed using the validated Arabic Gastrointestinal Symptom Rating Scale (GSRS). Domain and total scores (range 1–7) were compared between modalities; a GSRS total score ≥3 defined at least mild overall GI symptom burden. Results: Among 168 ESKD participants (mean age 43.4 ± 15.3 years; 116 HD, 52 PD), 92.2% reported at least one GI symptom. The prevalence of GSRS-defined symptoms was greater in PD (94.2%) than HD (91.4%). PD was associated with significantly higher mean scores in all GSRS domains (reflux, abdominal pain, indigestion, diarrhea, constipation) and a higher total GSRS score (3.33 ± 1.36 vs. 2.36 ± 0.71; p < 0.01 for all comparisons). Upper GI bleeding (UGIB) requiring hospitalization after dialysis initiation occurred more often in HD than PD (15.5% vs. 3.8%; OR 4.59; 95% CI 1.03–20.58). Conclusions: This study demonstrated that dialysis patients had a high prevalence of GI symptoms, with an elevated severity in patients on PD. These findings highlight the need for routine structured assessment of GI symptoms and modality-specific management strategies in dialysis units, particularly for patients on PD. Full article

Background: Handgrip strength (HGS) is a simple, low-cost indicator of muscle function and predictor of morbidity and mortality in patients with chronic kidney disease (CKD). Objective: To establish sex- and age-specific normative values for HGS in Colombian patients undergoing hemodialysis and to examine its association with clinical and biochemical factors. Methods: A multicenter, cross-sectional study was conducted between August and September 2023 in five cities across Colombia. A total of 436 hemodialysis patients aged 15 to over 80 years were assessed. HGS was measured post-dialysis using a CAMRY EH101 digital dynamometer in both flexion and extension of each arm. The Box–Cox Power Exponential (BCPE) model within the GAMLSS framework was used to generate percentile curves by sex. Comparisons were performed by sex, diabetes status, and occupation. Spearman’s correlation was used to explore associations between HGS and biochemical variables. Results: Males exhibited significantly higher HGS than females (mean difference: 8.09 kg; p < 0.001). Lower HGS was observed among individuals with diabetes and those unemployed. HGS showed a moderate inverse correlation with alkaline phosphatase (r = −0.29, p = 0.0014) and a weak inverse correlation with KT/V (r = −0.22, p = 0.02). No other biochemical markers showed significant associations. Reference percentiles (P3 to P97) were constructed for both sexes. Conclusions: These normative values for HGS represent the first reference standards for Colombian patients on hemodialysis. HGS assessment may support early identification of functional impairment and inform clinical decisions related to rehabilitation and nutritional support. Full article

Background: Kidney transplantation activity at the University Hospital of Guadeloupe was briefly interrupted at the onset of the COVID-19 pandemic, reflecting the global impact of this health crisis on organ transplantation. This study assessed patient and graft recovery in 335 recipients transplanted between 2013 and 2023, comparing those transplanted before 2020 and after the resumption of activity. The objective was to evaluate changes in recipient profiles, surgical parameters, and post-transplant outcomes following this disruption. Methods: This retrospective cohort included all kidney transplants performed at the University Hospital of Guadeloupe over a ten-year period. Most patients (70%) received transplants before 2020, with 30% afterward. All grafts were ABO-compatible, and 98.2% were from deceased donors. Trends in transplant activity were analyzed to identify variations over time, with a peak observed in 2018, followed by a decline until 2021 and a progressive recovery from 2022. Comparative analyses were performed to examine disparities in donor and recipient characteristics, ischemia durations, and outcomes between the two periods. Results: After 2020, recipients were more likely to be elderly (≥70 years), immunized, obese, have heterozygous sickle cell disease, or have polycystic kidney disease (p < 0.05). Mean cold ischemia time decreased (p = 0.009), while warm ischemia time increased (p < 0.001), reflecting procedural and logistical adaptations. Graft survival remained stable, with 97.5% at 6 months and 89.8% at 4 years for transplants before 2020, versus 100% and 96.9%, respectively, after 2020 (p = 0.160). Patient survival did not differ significantly between periods (p = 0.199). Independent factors associated with mortality included recipient age ≥ 60 years, diabetes, graft failure, transplantation before 2020, cold ischemia time ≥ 1200 min, and graft pyelonephritis. Conclusions: Despite the temporary suspension of activity and an increased proportion of transplants with expanded criteria after 2020, graft recovery and patient survival were not adversely affected. These findings suggest that kidney transplantation in Guadeloupe demonstrated strong resilience and capacity for adaptation during and after the COVID-19 crisis, maintaining outcomes comparable to the pre-pandemic period.

Background: Delayed graft function (DGF) is a frequent early complication after deceased donor kidney transplantation (DDKT), leading to prolonged hospitalization, increased risk of acute rejection, and reduced graft survival. Reliable and easily measurable preoperative biomarkers for DGF prediction remain limited. This study aimed to evaluate the predictive value of pre-operative Absolute Eosinophil Count (AEC) and Albumin-to-Globulin Ratio (AGR) for DGF in DDKT recipients. Methods: A retrospective analysis was conducted on all DDKT procedures performed at our institution between January 2018 and December 2023. Patients were divided into two groups: Group 1 (DGF) and Group 2 (non-DGF). DGF was defined as the requirement for hemodialysis within the first seven postoperative days. Demographic, clinical, and laboratory data—including pre-operative AEC and AGR—were collected and compared between groups. Statistical analysis was performed using appropriate parametric and nonparametric tests. Receiver operating characteristic (ROC) curves were generated to assess the individual and combined predictive performance of AEC and AGR for DGF. Results: A total of 38 patients underwent DDKT, comprising 27 males (71.05%) and 11 females (28.95%), with a mean age of 43.3 ± 9.41 years. Fifteen patients (39.47%) developed DGF. The mean AEC and AGR were significantly lower in the DGF group compared to the non-DGF group (AEC: 0.20 ± 0.16 vs. 0.40 ± 0.35, p = 0.04; AGR: 1.43 ± 0.22 vs. 1.66 ± 0.39, p = 0.02). ROC analysis demonstrated that both AEC (p = 0.04) and AGR (p = 0.04) were significant predictors of DGF. Combining both parameters resulted in a higher area under the curve (AUC), improved sensitivity, and enhanced negative predictive value (NPV) compared to either marker alone. Conclusions: DGF occurred in nearly two-fifths of DDKT recipients in this cohort. Patients with lower preoperative AEC and AGR were more likely to develop DGF, suggesting that these easily available hematological and biochemical indices can serve as potential preoperative predictors of early graft dysfunction. Future multicentric prospective studies are warranted to validate these findings and explore their integration into DGF risk prediction models. Full article

Background: The peritoneal dialysis (PD) catheter is commonly placed using an open surgery approach. However, mechanical peritoneal catheter-related complications are common causes of peritoneal dialysis technical failure. In recent years, laparoscopic procedures have been recommended because of less invasiveness and high effectiveness in reducing catheter dysfunction; however, this approach is burdened by higher costs and higher risks related to general anesthesia. Methods: We have developed a new advanced video-laparoscopy (ALS) approach with a simple technique that does not require general anesthesia. By using an ultrasound-guided procedure it is possible to place a PD catheter by regional anesthesia (Transversus Abdominis Plane (TAP) block associated with bilateral quadratus lumborum (QLB) block). Results: We here report the outcomes of 20 patients who underwent ALS implantation of straight-neck, double-cuffed Tenckhoff catheters using cutaneous anesthesia with TAP and QLB block. No major complications, including bleeding, were reported. No patient needed intravenous treatment for pain control, and all procedures were well tolerated. During a median follow-up of 21 months [IQR, 15–35] no mechanical complication was reported. Conclusions: ALS without general anesthesia is a simple and well-tolerated technique that can be used in patients at high risk. It therefore allows recruiting a greater number of patients for PD and ensuring well-performing catheters with lower risk of mechanical complications. Full article

Background: Renal arteriovenous malformations (rAVMs) are rare vascular anomalies that may lead to hematuria, anemia, or acute kidney injury (AKI). Although endovascular embolization is the treatment of choice, post-procedural complications such as new-onset proteinuria may occur and require long-term management. Case Presentation: A 56-year-old man with recurrent gross hematuria and elevated serum creatinine (128 μmol/L) was diagnosed with a right rAVM and underwent successful selective embolization. Despite recovery of renal function, follow-up revealed new-onset proteinuria (2.2 g/24 h). Results: Introduction of an angiotensin-converting enzyme inhibitor (ACEi) resulted in partial improvement of proteinuria, while subsequent addition of a sodium–glucose cotransporter-2 inhibitor (SGLT2i) achieved almost complete resolution of proteinuria (0.33 g/24 h) and stable renal function (serum creatinine 93 μmol/L) after 12 months. Conclusions: This case highlights the occurrence of post-embolization proteinuria and illustrates the synergistic renoprotective effect of combined ACEi and SGLT2i therapy in a non-diabetic patient with vascular kidney disease.

Hypertension (HTN) and chronic kidney disease (CKD) are significant global health burdens, with microalbuminuria (MA) serving as a key early marker of renal damage and cardiovascular risk. While nutritional interventions are pivotal for management, the evidence for specific nutrients is often complex and inconsistent, creating challenges for clinical guidance. This review critically evaluates current evidence on the interaction among macronutrients, micronutrients, and established dietary approaches and their influence on the development and course of HTN and MA. Strong consensus is present regarding sodium restriction, increased intakes of potassium, and the implementation of dietary patterns like Dietary Approaches to Stop Hypertension (DASH) and the Mediterranean diet to improve blood pressure and renal outcomes. Evidence favors protein moderation (approximately 0.8 g/kg/day), especially from plant sources, and emphasizes carbohydrate quality (e.g., high fiber, low glycemic index) over absolute quantity. The role of micronutrients is more nuanced; maintaining vitamin D sufficiency is protective, but intervention trials for many supplements, including B vitamins and antioxidant vitamins (C and E), have yielded inconsistent results. Several minerals, such as iron and selenium, exhibit a U-shaped risk curve where both deficiency and excess are detrimental, highlighting the risks of unselective supplementation. Ideal nutrition care prioritizes holistic dietary patterns over a focus on single nutrients. Clinical guidance should be founded on sodium reduction and potassium-rich foods, with personalized recommendations for protein and micronutrient supplementation based on an individual’s specific cardiovascular and renal profile. Future research must target nutrients with conflicting evidence to establish clear, evidence-based intake guidelines. Full article

Hemodialysis (HD) technology, pivotal in managing end-stage kidney disease, has witnessed significant advancements. Yet, the high cost of novel equipment often restricts its usage in resource-limited settings. This study introduces a two-filter adaptation to conventional HD machines, aimed at enhancing toxin removal while maintaining cost-effectiveness. Using a benchtop experimental setup, the performance of the adapted system was compared with that of standard HD. The results demonstrated that the two-filter system improved urea clearance rates by 54% compared with standard HD, without increasing albumin loss or causing additional hemolysis. In a pilot study of four HD patients, the modified setup achieved a higher single-pool Kt/V (1.82) and urea-reduction ratio (80%). These findings underscore the potential of this adaptation to enhance HD machine efficiency without additional patient risks, thereby offering a feasible solution for improving access to advanced renal therapies in under-resourced areas. Further clinical trials with larger populations are warranted to validate these benefits and evaluate middle-molecule clearance for comparison with hemodiafiltration (HDF). Full article

Background: Oral frailty is a new concept, introduced in Japan in 2013. In our preliminary study, oral hypofunction was observed in more than half of patients undergoing maintenance hemodialysis (MHD). This allowed us to determine the exact prevalence of oral frailty in MHD patients and investigate the association between oral cavity function, findings obtained via comprehensive geriatric assessment, and motor features. Methods: We initiated a two-week hospitalization program for MHD patients to evaluate frailty including oral cavity functions. Along with a comprehensive geriatric assessment and evaluation of motor functions, seven items pertaining to oral cavity functions were assessed by a professional dentist to determine oral frailty. After the incidence of each item had been determined, the association between these factors was retrospectively analyzed to explore the factors that affect oral frailty. Results: Oral frailty was observed in 33 out of 50 patients (66%). In particular, tongue lip motor functions were frequently impaired in this population. Oral cavity function scores, which increased as oral function deteriorated, negatively correlated with cognitive function (r = −0.349; p = 0.0129; 1−β = 0.71) and grip strength (r = −0.364; p = 0.00933; 1−β = 0.75). Conclusions: Oral frailty was commonly observed in MHD patients. We are currently considering implementing exercise programs to improve tongue lip motor function, enhance cognitive function through interprofessional cooperation, and strengthen grip. Full article

Background: Diabetic ketoacidosis (DKA) in patients with kidney failure receiving dialysis presents a formidable clinical challenge. Standard DKA protocols, designed for patients with preserved renal function, often fail in this cohort and can be unsafe when applied without modification. Patients are at risk of iatrogenic fluid overload, dyskalaemia, and hypoglycaemia due to altered insulin kinetics, impaired gluconeogenesis, and the absence of osmotic diuresis. Purpose: This narrative review aims to synthesise current understanding of DKA pathophysiology in dialysis patients, delineate distinct clinical phenotypes, and propose individualised management strategies grounded in physiology-based reasoning, comparative guideline insights, and consensus-supported literature. Methods: We searched PubMed/MEDLINE, Embase, and Google Scholar (January 2004–June 2024) for adult dialysis populations, using terms spanning DKA, kidney failure, insulin kinetics, fluid balance, and cerebral oedema. Reviews, observational cohorts, guidelines, consensus statements, and physiology papers were prioritised; case reports were used selectively for illustration. Evidence was weighted by physiological plausibility and practice relevance. Nephrology-led authors aimed for a pragmatic, safety-first synthesis, seeking and integrating contradictory recommendations. Conclusions: Our findings highlight the critical need for a nuanced approach to fluid management, a tailored insulin strategy that accounts for glucose-insulin decoupling and prolonged insulin half-life, and careful consideration of potassium and acidosis correction. We emphasise the importance of recognising specific volume phenotypes (hypovolaemic, euvolaemic, hypervolaemic) to guide fluid therapy, and advocating the judicious use of variable-rate insulin infusions (‘dry insulin’) to mitigate fluid overload. We also show that service-level factors are critical. Dialysis-specific pathways, interdisciplinary training, and quality improvement metrics can reduce iatrogenic harm. By linking physiology with workflow adaptations, this review provides a physiologically sound, bedside-oriented map for navigating this complex emergency safely and effectively. In doing so, it advances an individualised model of DKA care for dialysis-dependent patients. Full article

Background: Despite efforts to rely on arteriovenous fistulas/grafts for maintenance hemodialysis, a significant number of patients still depend on tunnel hemodialysis catheters for treatment. This poses a risk factor for central line-associated bloodstream infection (CLABSI) and, subsequently, vascular access compromise. Method: We conducted a retrospective study in five dialysis centers to determine the potential factors resulting in vascular access loss, CLABSI incidence, and microbe distribution patterns in Saudi Arabia at centers under the Ministry of National Guard Health Affairs. Adults who regularly received hemodialysis and had positive blood cultures between January 2019 and December 2023 were the subjects of the study. Results: Our study identified the presence of tunnel infection (p < 0.001), the presence of a Gram-negative pathogen (p = 0.036), and a high body mass index (BMI > 30) (p = 0.04) as potential risk factors leading to the loss of tunnel central venous catheters. In contrast, there was a lower probability of central venous catheter loss due to Gram-positive pathogens (p = 0.01). The CLABSI rate was 1.55 per 100 patients per month over a five-year period. Patients with CVC required more hospital treatment and had a significantly higher rate of vascular access loss (p < 0.001). Both central and peripheral blood cultures had nearly identical microbe spectra. Methicillin-sensitive Staphylococcus aureus (MSSA), Methicillin-resistant Staphylococcus aureus (MRSA), and Staphylococcus epidermidis had the highest prevalence rates among Gram-positive organisms. Among the Gram-negative bacteria, Enterobacter cloacae was the most common, followed by Klebsiella pneumonia and Pseudomonas aeruginosa. Conclusions: Our findings indicate the need for rigorous measures and interventions to prevent Gram-negative infections and decrease the reliance on central venous catheters, to decrease infections in hemodialysis patients, and decrease morbidity and cost. Strict hand hygiene, patient education, and surveillance programs are recommended to monitor these patients. Full article
