Efficacy and safety of intracavitary electrocardiography-guided peripherally inserted central catheters in pediatric patients: a systematic review and meta-analysis

Objective To assess the efficacy and safety of intracavitary electrocardiography (IC-ECG)-guided peripherally inserted central catheter (PICC) placements in pediatric patients, emphasizing improvements over traditional placement methods. Methods A literature search was conducted in April 2024 across PubMed, Cochrane Library, and EMBASE. Studies focusing on pediatric patients and reporting the efficacy and safety of IC-ECG-guided PICC placement via the upper extremity were included. This study was registered with the PROSPERO database (CRD42024549037) in accordance with PRISMA guidelines. Results Eleven studies were included, comprising five randomized controlled trials (RCTs) and six quasi-experimental studies. The pooled analysis showed that IC-ECG had an applicability and feasibility of 97% and 98%, respectively. The first puncture success rate was 91%, and the overall success rate was 98%. Sensitivity and specificity were 97% and 80%, respectively. IC-ECG significantly reduced overall complications compared to traditional methods (RR: 0.31, 95% CI [0.20–0.46], p < 0.00001), particularly in phlebitis (RR: 0.25, 95% CI [0.11–0.57], p = 0.001) and arrhythmias (RR: 0.09, 95% CI [0.01–0.70], p = 0.021). Similar results were observed in neonates. Only one case of catheter-related bloodstream infection (CRBSI) was reported, and no arrhythmia events were noted. Conclusion IC-ECG-guided PICC placement is a highly effective and safe method for pediatric patients, including neonates, offering significant advantages over traditional techniques. Further high-quality studies are needed to standardize procedural techniques and explore cost-effectiveness.

Incidence, Risk Factors, Organism Types, and Outcomes of Catheter-Related Bloodstream Infections in Hemodialysis Patients.

Background Patients undergoing hemodialysis for End-Stage Renal Disease (ESRD) are at risk for Hemodialysis Catheter-Related Bloodstream Infections (CRBSIs). This study evaluates the incidence, risk factors, organism types, and outcomes of CRBSI in adult patients on maintenance hemodialysis at King Faisal Hospital, Rwanda. Methods This was a prospective cohort study of adult patients with end-stage renal disease undergoing hemodialysis via central venous hemodialysis catheters at King Faisal Hospital, Rwanda. Upon receiving the IRB approval, 81 eligible patients, women, and men aged between 19 and 74, were enrolled. Restricted Mean Survival Time (RMST) analysis evaluated the risk factors for CRBSI. The statistical significance was determined using p-values, with a cut-off of 0.05. Results The incidence of CRBSI was found to be 0.78 episodes per 1,000 catheter-days. Acute hemodialysis catheter type and anemia were associated with increased risk for CRBSI, with a P-value less than 0.05. In addition, all CRBSI cases were due to bacteria, with 52.63% gram-negative and 47.37% gram-positive. Out of 19 CRBSI events,nine cases (47.37%) required hospitalization with a median duration of seven days. Approximately half of the CRBSIs required catheter removal. No metastatic infection or death was noted. Conclusion The present study demonstrated that our hemodialysis unit has an incidence of 0.78 episodes per 1,000 catheter-days. Catheter type and anemia were significantly associated with CRBSI.

A Local Experience of Antibiotic Lock Therapy as an Adjunctive Treatment for Central Venous Catheter-Related Bloodstream Infections in Pediatric Oncology and Hematology Patients.

One of the main drawbacks of tunneled central venous catheters (CVCs) is catheter-related bloodstream infections (CRBSIs). Antibiotic lock therapy (ALT) can be combined with systemic antibiotics to achieve catheter salvage. Our objectives are to describe cases of CRBSI and our experience with ALT in a pediatric oncology-hematology ward. a retrospective descriptive study of pediatric CRBSI cases in a Spanish oncology-hematology unit from 2007 to 2017 was conducted. We collected demographic, clinical, and microbiological data from all patients. fifty-eight CRBSIs were diagnosed in thirty-nine patients; 72.9% of these patients were male, with a median age of 42.1 months. The main underlying diseases were leukemia/lymphoma (51.7%) and solid tumors (32.7%). Thirty-five (60.3%) CRBSIs were caused by Gram-positive cocci, of which 70.6% were coagulase-negative Staphylococci, and sixteen (27.6%) were caused by Gram-negative bacilli. We treated 41/58 (71%) cases with ALT. A total of 12/17 (71%) CVCs that were not treated with adjunctive ALT were removed, compared with 13/41 (32%) that were treated with ALT (relative risk (RR), 0.449; confidence interval (CI), 95%: 0.259-0.778, p = 0.004). Major reasons to remove the CVC in the CRBSI-ALT group were local insertion/pocket site infection (23%), persistent symptoms (23%), and infectious' relapses (15%). ALT was shown to be an effective approach to keeping the CVC in place, with no added adverse effects.

Epidemiology and Clinical Insights of Catheter-Related Candidemia in Non-ICU Patients with Vascular Access Devices.

Vascular access devices (VADs), namely peripheral VADs (PVADs) and central venous VADs (CVADs), are crucial in both intensive care unit (ICU) and non-ICU settings. However, VAD placement carries risks, notably catheter-related bloodstream infections (CRBSIs). Candida spp. is a common pathogen in CRBSIs, yet its clinical and microbiological characteristics, especially in non-ICU settings, are underexplored. We conducted a monocentric, retrospective observational study at Luigi Sacco Hospital from 1 May 2021 to 1 September 2023. We reviewed medical records of non-ICU adult patients with CVADs and PVADs. Data on demographics, clinical and laboratory results, VAD placement, and CRBSI occurrences were collected. Statistical analysis compared Candida spp. CRBSI and bacterial CRBSI groups. Out of 1802 VAD placements in 1518 patients, 54 cases of CRBSI were identified, and Candida spp. was isolated in 30.9% of episodes. The prevalence of CRBSI was 3.05%, with Candida spp. accounting for 0.94%. Incidence rates were 2.35 per 1000 catheter days for CRBSI, with Candida albicans and Candida non-albicans at 0.47 and 0.26 per 1000 catheter days, respectively-patients with Candida spp. CRBSI had more frequent SARS-CoV-2 infection, COVID-19 pneumonia, and hypoalbuminemia. During the COVID-19 pandemic, Candida spp. was a notable cause of CRBSIs in our center, underscoring the importance of considering Candida spp. in suspected CRBSI cases, including those in non-ICU settings and in those with PVADs.

Clinical application of intracavitary electrocardiogram localization combined with ultrasound in central venous catheterization in critically ill patients: An observational study.

To explore the clinical application value of intracavitary electrocardiogram (ECG) localization combined with ultrasound in central venous catheterization in critically ill patients. A total of 103 patients who were treated in the intensive care unit of our hospital from October 2020 to June 2023 were selected as the study subjects, and according to the differences in their central venous catheter placement methods, they were divided into study group (n = 52, receiving ultrasound combined with intracavitary ECG localization for catheterization) and control group (n = 51, receiving routine catheterization). The differences in the catheter placement accuracy, catheter depth, catheter placement duration, incidence of catheter-related complications, length of stay, and hospitalization expenses between the 2 groups were compared. The analysis utilizing X-ray for catheter tip positioning indicated that the catheter tip placement rate was higher in the study group than in the control group, and the catheter tip malposition rate was lower than in the control group (P < .05). There was no statistical significance in the catheter depth between study group and control group (P > .05), and the catheter placement duration of study group was significantly lower than that of control group, with statistical significance (P < .05). One case of partial catheter blockage, one case of catheter-related bloodstream infection, and one case of phlebitis were observed in study group, with an overall incidence of complications of 5.77% (3/52), which was significantly lower than 21.57% (11/51) of control group (P < .05). The length of stay and hospitalization expenses in study group were significantly lower than those in control group, with statistical significance (P < .05). The combined use of ultrasound and intracavitary ECG localization in critically ill patients undergoing central venous catheterization can help increase the success rate of catheter placement, shorten the catheter placement duration, reduce the incidence of various catheter-related complications, and also reduce the length of stay and hospitalization expenses.

Glucocorticoid use and parenteral nutrition are risk factors for catheter-related Candida bloodstream infection: a retrospective study.

Catheter-related candidemia (CRC) is a serious catheter-related bloodstream infection (CRBSI) caused by Candida spp., with higher mortality than CRBSIs caused by other organisms. To identify the risk factors for Candida CRBSI. The clinical characteristics of 297 patients with CRBSI in a local hospital from January 2007 to June 2015 were collected, including 33 Candida CRBSI and 264 non-Candida CRBSI. The associations of Candida CRBSI with the clinical variables were examined using univariate and multivariate analyses. Multivariate analysis showed that glucocorticoid use (odds ratio [OR] = 10.313, 95% confidence interval [CI] = 2.032-52.330, P = 0.005) and parenteral nutrition (OR = 5.400, 95% CI = 0.472-61.752, P = 0.0175) were independent risk factors for Candida CRBSI. The most prevalent species were Candida tropicalis (42.4%) and Candida albicans (36.36%). Of the 33 Candida CRBSI cases, 31 (93.93%) had indwelling central venous catheters (CVC) for ≥14 d. The mortality of Candida CRBSI was remarkably higher than that of bacteria CRBSI. Patients with timely catheter removal and appropriate antifungal treatment had dramatically increased 28-d survival compared with those with untimely catheter removal + inappropriate antifungal treatment (88.89% vs. 0, P = 0.006). The study identified glucocorticoid use and parenteral nutrition as independent risk factors for Candida CRBSI. The outcome of candidemia was associated with the duration of CVC indwelling and antifungal treatment.

Comparing conventional and modified Seldinger techniques using a micro-insertion kit for PICC placement in neonates: a retrospective cohort study.

This study aims to assess the comparative effectiveness of a conventional splitting needle or a peelable cannula vs. the modified Seldinger technique (MST) by utilizing a dedicated micro-insertion kit across various clinically significant metrics, including insertion success, complications, and catheter-related infections. We conducted a retrospective observational cohort study using an anonymized data set spanning 3 years (2017-2019) in a large tertiary-level neonatal intensive care unit in Qatar. A total of 1,445 peripherally inserted central catheter (PICC) insertion procedures were included in the analysis, of which 1,285 (89%) were successful. The primary indication for insertion was mainly determined by the planned therapy duration, with the saphenous vein being the most frequently selected blood vessel. The patients exposed to MST were generally younger (7 ± 15 days vs. 11 ± 26 days), but exhibited similar mean weights and gestational ages. Although not statistically significant, the MST demonstrated slightly higher overall and first-attempt insertion success rates compared to conventional methods (91 vs. 88%). However, patients undergoing conventional insertion techniques experienced a greater incidence of catheter-related complications (p < 0.001). There were 39 cases of catheter-related bloodstream infections (CLABSI) in the conventional group (3.45/1,000 catheter days) and eight cases in the MST group (1.06/1,000 catheter days), indicating a statistically significant difference (p < 0.001). Throughout the study period, there was a noticeable shift toward the utilization of the MST kit for PICC insertions. The study underscores the viability of MST facilitated by an all-in-one micro kit for neonatal PICC insertion. Utilized by adept and trained inserters, this approach is associated with improved first-attempt success rates, decreased catheter-related complications, and fewer incidences of CLABSI. However, while these findings are promising, it is imperative to recognize potential confounding factors. Therefore, additional prospective multicenter studies are recommended to substantiate these results and ascertain the comprehensive benefits of employing the all-in-one kit.

Adding vortexing to the Maki technique provides no benefit for the diagnosis of catheter colonization or catheter-related bacteremia.

A previous study compared vortexing and Maki techniques for the diagnosis of catheter-related bloodstream infection (CRBSI), and concluded that vortexing was not superior to Maki method. To determine whether the combined use of vortexing and Maki techniques provides profitability versus the Maki technique for the diagnosis of catheter tip colonization (CTC) and CRBSI. Observational and prospective study carried out in an Intensive Care Unit. Patients with suspected catheter-related infection (CRI) and with one central venous catheter for at least 7 days were included. The area under the curve (AUC) of the Maki technique, the vortexing technique and the combination of both techniques for the diagnosis of CTC and CRBSI were compared. We included 136 episodes of suspected CRI. We found 21 cases of CTC of which 10 were also CRBSI cases. Of the 21 CTC episodes, 18 (85.7%) were diagnosed by Maki technique and vortexing technique, 3 (14.3%) only by the technique of Maki, and none only by technique of vortexing. Of the 10 CRBSI episodes, 9 (90.0%) were diagnosed by the techniques of Maki and vortexing, 1 (10.0%) was diagnosed only by the technique of Maki, and none only by the technique of vortexing. We no found differences in the comparison of AUC between the technique of Maki and the combination of Maki and vortexing techniques for the diagnosis of CTC (P = 0.99) and CRBSI (P = 0.99). The novel finding of our study was that the combined use of vortexing and Maki techniques did not provide profitability to the technique of Maki alone to CRBSI diagnosis of.

CLINICO-MICROBIOLOGICAL SPECTRUM OF HEMODIALYSIS CATHETER-RELATED BLOOD STREAM INFECTIONS: A CONCISE REVIEW

The disease burden of chronic kidney disease is increasing worldwide, and with the growing population of patients requiring hemodialysis, more patients are placed on central venous catheters (CVCs). Vascular access infections significantly cause hospitalization and mortality among end-stage renal disease (ESRD) patients. As per the data from the United States, Gram-positive organisms account for almost 56% of the total cases of catheter-related bloodstream infection (CRBSI), in stark contrast to Indian studies showing a dominance of Gram-negative organisms. The prolonged use of non-tunnelled catheters, poor hygiene, lack of catheter care protocols, and the tropical climate pose unique challenges to control CRBSIs in resource-poor countries. The most effective strategy to prevent CRBSI is to minimize the duration of dialysis catheters. Other strategies include the introduction of strict catheter care protocols, using tunnelled cuffed catheters, anti-microbial lock solutions, and topical antimicrobials. Eradicating nasal carriage of Staphylococcus aureus also reduced the incidence of CRBSIs.Treatment of suspected CRBSI should be promptly initiated with empirical broad-spectrum antibiotics covering Gram-positive and Gram-negative organisms. Catheter removal is indicated only if the patient is clinically unstable, has metastatic infections, and those who do not respond to antibiotic therapy.

Three Cases of Catheter-related Bloodstream Infection Caused by Phialemonium curvata : A Case Report and Literature Review.

With recent developments in the field of microbiology, an increasing number of yeasts and molds with the potential to cause infections in humans are identified every year. In addition to the challenges in identifying clinical isolates, there is limited antifungal susceptibility data available for Phialemonium species, leading to uncertainty in optimal treatment recommendations. In this article, catheter-related bloodstream infections caused by Phialemonium curvata (previously Phialemonium curvatum ) in 3 immunosuppressed patients are presented. Furthermore, the literature was reviewed to identify the clinical spectrum and treatment approaches for the reported infections. The cases presented here were analyzed along with 24 cases reported in the literature. Among all cases, 21 (77.7%) patients had an underlying condition. Nine (33.3%) patients had hematologic/oncologic malignancies and solid organ transplants. Twenty-two (81.4%) patients had a history of device or invasive interventions. Surgical procedures, removal of contaminated devices or tissue were found to reduce the risk of death by 86.7%. Correspondence analysis revealed a significant association between antifungal treatment and outcome ( P < 0.001). The correspondence analysis could explain 53.9% of this relationship. Monotherapy and combination therapy were associated with survival. While salvage treatment or no antifungal therapy was associated with mortality, intravitreal injection or topical application of voriconazole was associated with sequelae. Surgical intervention and removal of contaminated devices or tissue should be considered at an early stage.

Complications and Practice Variation in the Use of Peripherally Inserted Central Venous Catheters in People With Cystic Fibrosis: The Prospective Study of Peripherally Inserted Venous Catheters in People With Cystic Fibrosis Study

Peripherally inserted central catheters (PICCs) are used commonly to administer antibiotics to people with cystic fibrosis (CF), but their use can be complicated by venous thrombosis and catheter occlusion. Which participant-, catheter-, and catheter management-level attributes are associated with increased risk of complications of PICCs among people with CF? This was a prospective observational study of adults and children with CF who received PICCs at 10 CF care centers in the United States. The primary end point was defined as occlusion of the catheter resulting in unplanned removal, symptomatic venous thrombosis in the extremity containing the catheter, or both. Three categories of composite secondary outcomes were identified: difficult line placement, local soft tissue or skin reactions, and catheter malfunction. Data specific to the participant, catheter placement, and catheter management were collected in a centralized database. Risk factors for primary and secondary outcomes were analyzed by multivariate logistic regression. Between June 2018 and July 2021, 157 adults and 103 children older than 6 years with CF had 375 PICCs placed. Patients underwent 4,828 catheter-days of observation. Of the 375 PICCs, 334 (89%) were≤ 4.5 F, 342 (91%) were single lumen, and 366 (98%) were placed using ultrasound guidance. The primary outcome occurred in 15 PICCs for an event rate of 3.11 per 1,000 catheter-days. No cases of catheter-related bloodstream infection occurred. Other secondary outcomes developed in 147 of 375 catheters (39%). Despite evidence of practice variation, no risk factors for the primary outcome and few risk factors for secondary outcomes were identified. This study affirmed the safety of contemporary approaches to inserting and using PICCs in people with CF. Given the low rate of complications in this study, observations may reflect a widespread shift to selecting smaller-diameter PICCs and using ultrasound to guide their placement.

Prospective clinical study on the incidence of catheter-related complications in a neurological intensive care unit: 4 years of experience.

Over the past decades, significant efforts have been made to reduce early and late catheter-related complications in critically ill patients, using approaches based on bundles of evidence-based interventions. In this prospective clinical study, the authors evaluated the incidence of catheter-related complications in their neuro-intensive care unit during a 4-year period, adopting systematically the GAVeCeLT bundles for the insertion and management of all central venous access devices: centrally inserted central catheters (CICCs), peripherally inserted central catheters (PICCs) and femorally inserted central catheters (FICCs). All early/immediate and late complications were recorded. On 486 central lines (328 CICCs, 149 PICCs and 9 FICCs), the only clinically relevant early/immediate complication was primary tip malposition (1%). In regards late infective complications, the authors did not record any case of catheter-related bloodstream infection; though, they observed one case of central line associated blood stream infection (one CICC; 0.14/1000 catheter days), and 15 cases of catheter colonization (12 CICCs and 3 PICCs; 2.09 episodes/1000 catheter days). Late non-infective complications were few: 14 accidental dislodgments (2.9%), 18 irreversible lumen occlusions (3.7%), and no episodes of symptomatic catheter-related thrombosis or tip migration. The systematic adoption of the GAVeCeLT bundles for CVAD insertion and maintenance was associated with a minimization of catheter-related complications. The strict adherence to the recommendations included in these bundles was the major determinant for clinical success.

Sonication did not provide reliability to Maki technique for catheter related bloodstream infection diagnosis.

ObjectiveThe aim of our study was to analyze sonication and Maki techniques for diagnosis of catheter tip colonization and catheter-related bloodstream infection (CRBSI) on patients admitted to ICU.Material and methodsObservational and prospective study in one Intensive Care Unit. Patients with some central venous catheter (CVC) at least for 7 days and catheter-related infection (CRI) suspicion (new episode of fever or sepsis) were included. We performed Maki technique followed by sonication of catheter tip. We compared area under the curve (AUC) of Maki, sonication, and techniques combination to diagnosis catheter tip colonization and CRBSI.ResultsWe included 94 CVC from 87 CRI suspicion episodes. We found 14 cases of catheter tip colonization and 10 cases of CRBSI. Of the 14 catheter tip colonization cases, 7 (50.0%) were detected by Maki and sonication techniques, 6 (42.9%) were detected only by Maki technique, and 1 (7.1%) was detected only by sonication technique. Of the 10 CRBSI, 6 (60.0%) were detected by Maki and sonication techniques, 4 (40.0%) were detected only by Maki technique, and any only by sonication technique. We found higher AUC in Maki technique than in sonication technique to diagnosis of CRBSI (p=0.02) and to diagnosis of catheter tip colonization (p=0.03). No significant differences were found in AUC between Maki technique and combination techniques for diagnosis of catheter tip colonization (p=0.32) and of CRBSI (p=0.32).Conclusion.:Sonication did not provide reliability to Maki technique for diagnosis of catheter tip colonization and CRBSI.

First human case of catheter-related blood stream infection caused by Staphylococcus schleiferi subspecies coagulans: a case report and literature review

BackgroundStaphylococcus schleiferi is a gram-positive pathogenic coccus which causes canine skin and ear infections. Only four cases of human infection caused by Staphylococcus schleiferi subspecies coagulans have been reported. Herein, we present the first case of catheter-related bloodstream infection caused by S. schleiferi subspecies coagulans.Case presentationA 62-year-old Japanese man was admitted to our hospital for examination of sigmoid colon tumor. During hospitalization, he had fever, shaking chills, and swelling at the peripheral venous catheter insertion site. Two sets of blood cultures were positive for S. schleiferi subspecies coagulans which was confirmed using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS), 16S ribosomal RNA sequencing and the coagulase test. The patient was successfully treated without relapse.ConclusionTo our knowledge, this is the first report of catheter-related bloodstream infection caused by S. schleiferi subspecies coagulans. S. schleiferi subsp. coagulans can be pathogenic in humans, and MALDI-TOF MS can contribute to accurate identification of S. schleiferi subspecies coagulans.

Risk Factors of Candida parapsilosis Catheter-Related Bloodstream Infection.

Catheter-related bloodstream infection (CRBSI) is an important healthcare-associated infection caused by various nosocomial pathogens. Candida parapsilosis has emerged as a crucial causative agent for the CRBSI in the last two decades. Many factors have been associated with the development of CRBSI including, demography, pre-maturity, comorbidities (diabetes mellitus, hypertension, heart diseases, neuropathy, respiratory diseases, renal dysfunction, hematological and solid organ malignancies, and intestinal dysfunction), intensive care unit (ICU) admission, mechanical ventilation (MV), total parenteral nutrition (TPN), prior antibiotic and/or antifungal therapy, neutropenia, prior surgery, immunosuppressant, and type, site, number, and duration of catheters. This study aims to determine C. parapsilosis CRBSI risk factors. A retrospective study has been performed in an 853-bedded tertiary-care hospital in north-eastern Malaysia. All inpatients with C. parapsilosis positive blood cultures from January 2006 to December 2018 were included, and their medical records were reviewed using a standardized checklist. Out of 208 candidemia episodes, 177 had at least one catheter during admission, and 31 cases had not been catheterized and were excluded. Among the 177 cases, 30 CRBSI cases were compared to 147 non-CRBSI cases [81 bloodstream infections (BSIs), 66 catheter colonizers]. The significance of different risk factors was calculated using multivariate analysis. Multivariate analysis of potential risk factors shows that ICU admission was significantly associated with non-CRBSI as compared to CRBSI [OR, 0.242; 95% CI (0.080–0.734); p = 0.012], and TPN was significantly positively associated with CRBSI than non-CRBSI [OR, 3.079; 95%CI (1.125–8.429); p = 0.029], while other risk factors were not associated significantly. Patients admitted in ICU were less likely to develop C. parapsilosis CRBSI while patients receiving TPN were more likely to have C. parapsilosis CRBSI when compared to the non-CRBSI group.

KOCURIA SPECIES: EMERGING PATHOGENS IN CHILDREN WITH CENTRAL VENOUS CATHETER, A CASE REPORT AND REVIEW OF LITERATURE

Kocuria species (KS) are gram-positive, coagulase-negative coccoids. Reports about KS infection in children are limited. We performed a short-review of literature and described a case of catheter related-bloodstream infection (CR-BSI) caused by KS. Electronic search through PubMed was conducted using the keywords: “Kocuria” AND “children” AND “sepsis”. The earliest publication date was of 2008, the latest of 2017 We analyzed 7 articles with 15 cases described. KS were responsible of endocarditis in 1 child, CR-BSI in 13 children and spontaneous bacterial peritonitis in 2 children. Most were immunocompromised hosts and CVC-carriers (2 short-bowel syndrome, 2 tumor, 1 congenital tufting-enteropathy, 1 Hirschsprung's disease, 1 methylmalonic-aciduria, 6 prematurity). Only 1 was an otherwise healthy child. Case report: during the COVID-19 lockdown, a 17yeas-old boy affected by Hirschsprung's disease and CVC-carrier developed fever, chills, vomit and hematuria. Due to “hospital fear”, he began empirical therapy with ceftriaxone at home, without symptoms resolution. Once admitted to the department, blood exams showed: normal lymphocyte immunophenotyping, thrombocytopenia, increased CRP and hyperbilirubinaemia. Haematuria, proteinuria and glycosuria also occurred. Culturing blood samples showed KS infection. Echocardiography was normal. Basing on the antibiogram, we started treatment with vancomycin with rapid patient recovery. The use of CVCs in immunocompromised patients represents the most important risk factor for KS-BSI. Due to the limited number of reports about this infection, there are no guidelines to manage it.In patients with a chronic disease, opportunistic pathogens as KS must be considered, also because symptoms and complications are still unknown.
