RESUMEN

Aging of the vascular system is associated with deep changes of the structural proprieties of the arterial wall. Arterial hypertension, diabetes mellitus, and chronic kidney disease are the major determinants for the loss of elasticity and reduced compliance of vascular wall. Arterial stiffness is a key parameter for assessing the elasticity of the arterial wall and can be easily evaluated with non-invasive methods, such as pulse wave velocity. Early assessment of vessel stiffness is critical because its alteration can precede clinical manifestation of cardiovascular disease. Although there is no specific pharmacological target for arterial stiffness, the treatment of its risk factors helps to improve the elasticity of the arterial wall.

RESUMEN

Splenic marginal zone lymphoma (SMZL) is a rare lymphoproliferative disease involving B-cells and affecting elderly patients. SMZL plague peripheral blood and bone marrow, spleen. Lymph nodes are generally spared. SMZL is due to a protracted antigen stimulation of B lymphocytes and of microenvironment leading B-cell to polyclonal and then oligoclonal/monoclonal growth, promoting lymphoproliferation. Integration of the NOTCH2 and NFk-B signaling has been recently identified as the primary mechanism of neoplastic proliferation in SMZL. In total 20% of cases carry mutations in NOTCH2. Although SMZL has an indolent course, progression to diffuse large B-cell lymphoma occurs in about 10-15% of patients. Establishing the prognosis is a key step in disease management, depending on both individual risk and patients' health status. This review discusses tailored treatment of SMZL patients. Progression risk factors include nodal and extra-nodal involvement, peripheral lymphocytosis, anemia and thrombocytopenia. Patients with two or more score points have a median survival of <5 years. Watch and wait strategy is appropriate in low-risk and asymptomatic patients, whereas treatment of symptomatic patients ranges from splenectomy to rituximab monotherapy or associated with chemotherapy.

RESUMEN

R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) has been considered the standard of care for diffuse large B cell lymphoma (DLBCL) patients, including in the elderlies, and represent the current standard treatment. Ineligibility for R-CHOP-like treatments seems to be associated with shorter survival. Recent studies have shown that bendamustine and rituximab is linked, in elderly patients affected by DLBCL. Here we report our experience with BR in 40 elderly frail patients affected by DLBCL ineligibles for R-CHOP. The OOR was 77.5%, with 22 complete responses and 9 partial responses statistical analysis showed no significant difference in overall survival (OS) between patients aged 80 years and older and patients younger than 80 years (6·4 vs. 10·2 months, respectively, P = 0·43). Complete responders were more likely patients with good performance status, (ECOG 0-1) 13 patients (60%), 9 patients (40%) were ECOG 2; of the 9 patients who achieved partial response, 7 patients had ECOG 0-1 and 2 patients had ECOG 2. Four patients had stable disease. Progression-free survival (PFS) median PFS was 13.5 months. These preliminary results showed that bendamustine and rituximab has been associated with high response rates, acceptable toxicity in frail DLBCL patients and high rate of OSS. In older patients with advanced IPI scores, no significant difference in OS were observed between patients aged 80 years and older and patients younger than 80 years. We conclude that bendamustine and rituximab seems to be a reasonable alternative for frail DLBCL patients.

RESUMEN

BACKGROUND: Noninvasive respiratory support (NIRS) has been diffusely employed outside the intensive care unit (ICU) to face the high request of ventilatory support due to the massive influx of patients with acute respiratory failure (ARF) caused by coronavirus-19 disease (COVID-19). We sought to summarize the evidence on clinically relevant outcomes in COVID-19 patients supported by NIV outside the ICU. METHODS: We searched PUBMED®, EMBASE®, and the Cochrane Controlled Clinical trials register, along with medRxiv and bioRxiv repositories for pre-prints, for observational studies and randomized controlled trials, from inception to the end of February 2021. Two authors independently selected the investigations according to the following criteria: (1) observational study or randomized clinical trials enrolling ≥ 50 hospitalized patients undergoing NIRS outside the ICU, (2) laboratory-confirmed COVID-19, and (3) at least the intra-hospital mortality reported. Preferred Reporting Items for Systematic reviews and Meta-analysis guidelines were followed. Data extraction was independently performed by two authors to assess: investigation features, demographics and clinical characteristics, treatments employed, NIRS regulations, and clinical outcomes. Methodological index for nonrandomized studies tool was applied to determine the quality of the enrolled studies. The primary outcome was to assess the overall intra-hospital mortality of patients under NIRS outside the ICU. The secondary outcomes included the proportions intra-hospital mortalities of patients who underwent invasive mechanical ventilation following NIRS failure and of those with 'do-not-intubate' (DNI) orders. RESULTS: Seventeen investigations (14 peer-reviewed and 3 pre-prints) were included with a low risk of bias and a high heterogeneity, for a total of 3377 patients. The overall intra-hospital mortality of patients receiving NIRS outside the ICU was 36% [30-41%]. 26% [21-30%] of the patients failed NIRS and required intubation, with an intra-hospital mortality rising to 45% [36-54%]. 23% [15-32%] of the patients received DNI orders with an intra-hospital mortality of 72% [65-78%]. Oxygenation on admission was the main source of between-study heterogeneity. CONCLUSIONS: During COVID-19 outbreak, delivering NIRS outside the ICU revealed as a feasible strategy to cope with the massive demand of ventilatory assistance.

RESUMEN

BACKGROUND: Hereditary angioedema due to C1 inhibitor deficiency (C1-INH-HAE) is a rare disease. Few states in developing countries have an adequate management of HAE, but none of them belongs to the former USSR area. This study analyses data from C1-INH-HAE patients from Belarus. METHODS: Data about clinical characteristics, genetics, access to diagnosis and treatment were collected from 2010 by the Belarusian Research Center for Pediatric Oncology, Hematology and Immunology in Minsk. A questionnaire about attacks, prophylactic (LTP) and on-demand therapy (ODT) was administered to patients. RESULTS: We identified 64 C1-INH-HAE patients belonging to 26 families, 27 (42.2%) of which were diagnosed in the last 3 years. The estimated minimal prevalence was 1:148,000. Median age at diagnosis was 29 years, with diagnostic delay of 19 years. Thirty-eight patients answered a questionnaire about therapy. Eleven patients did not use any treatment to resolve HAE attacks. Twenty-seven patients underwent ODT: 9 with appropriate treatments, and 18 with inappropriate treatments. Nine patients used LTP with attenuated androgens and 1 with tranexamic acid. Thirty-two patients answered a questionnaire about attacks and triggers: 368 angioedema attacks were reported, with an average of 10 attacks per year. We found 24 different SERPING1 variants: 9 missenses, 6 in splice sites, 6 small deletions, 2 nonsense, 1 large deletion; 7 have not been previously described. De novo variants were found in 11 patients. CONCLUSIONS: C1-INH-HAE diagnosis and management in Belarus is improved as seen from the high number of new diagnosis in the last 3 years. Next steps will be to reduce the diagnostic delay and to promote the LTP and ODT.

RESUMEN

Myelodisplastic syndromes (MDS) are heterogeneous myeloid disorders characterized by peripheral cytopenias and increased risk of transformation into acute myelogenous leukemia (AML). MDS are generally suspected in the presence of cytopenia on routine analysis and the evaluation of bone marrow cells morphology and cellularity leads to correct diagnosis of MDS. The incidence of MDS is approximately five cases per 100,000 people per year in the general population, but it increases up to 50 cases per 100,000 people per year after 60 years of age. Typically MDS affect the elderly, with a median age at diagnosis of 65-70 years. Here the current therapeutic approaches for MDS are evaluated by searching the PubMed database. Establishing the prognosis in MDS patients is a key element of therapy. In fact an accurate estimate of prognosis drives decisions about the choice and timing of the therapeutic options. Therapy is selected based on prognostic risk assessment, cytogenetic pattern, transfusion needs and biological characteristics of the disease, comorbidities and clinical condition of the patients. In lower-risk patients the goals of therapy are different from those in higher-risk patients. In lower-risk patients, the aim of therapy is to reduce transfusion needs and transformation to higher risk disease or AML, improving the quality of life and survival. In higher-risk patients, the main goal of therapy is to prolong survival and to reduce the risk of AML transformation. Current therapies include growth factor support, lenalidomide, immunomodulatory and hypomethylating agents, intensive chemotherapy, and allogenic stem cell transplantation. The challenge when dealing with MDS patients is to select the optimal treatment by balancing efficacy and toxicity.

RESUMEN

Bortezomib-dexamethasone (bort-dex) is effective for relapsed/refractory (R/R) multiple myeloma, but few data are available for elderly patients. The aim of this study was to evaluate efficacy and toxicity of bort-dex in elderly R/R MM patients. We evaluated 81 R/R MM patients treated with bort-dex. Eight of them had light-chain disease. The median age of the patients was 73 years (range 65-89 years). All patients were R/R MM patients and had been treated with melphalan and prednisone with or without thalidomide or bortezomib in the first line or with lenalidomide and dexamethasone in the second line. The median number of previous lines was 2. Thirty-nine (48%) patients received bortezomib intravenously and 42 (52%) patients received bortezomib subcutaneously. The median number of bort-dex cycles was 6 (range 1-11). Fifty-three (65.4%) patients achieved at least a partial response, including eight (11%) patients with complete response and nine (12.5%) patients with very good partial responses. The median duration of response, time to next therapy and treatment-free intervals were 8, 11 and 5 months. Duration of response was significantly longer for patients achieving complete response/very good partial response than for those achieving partial response (7.3 vs. 3.8 months, P=0.03). After a median follow-up of 24 months, 78 patients showed disease progression and 70 died. The median time to progression, progression-free survival and overall survival were 8.9, 8.7 and 22 months, respectively. Peripheral neuropathy occurred in 38 (47%) patients. Our data highlight that bort-dex is effective and tolerable in fit elderly patients, thus justifying the efforts for deeper responses. However, awareness of short-lived responses to bort-dex should lead to a thorough evaluation of the need for maintenance.

RESUMEN

BACKGROUND: Hereditary angioedema (HAE) due to C1-inhibitor (C1-INH) deficiency is characterized by unpredictable recurrent episodes of swelling affecting the skin and the mucosa tissues, including gastrointestinal tract and/or oropharyngeal-laryngeal mucosae. Long-term prophylaxis (LTP) is used to prevent attacks. OBJECTIVE: Because C1-INH plays a pivotal role in several biological pathways, we investigated the possible association of comorbidities with C1-INH deficiency and the use of LTP with attenuated androgens (AA) or tranexamic acid (TXA). METHODS: This retrospective cohort study involved adult patients with HAE referred to Milan and Padua angioedema centers in the period 1979-2021. A qualitative comparison was performed to analyze comorbidities versus general population. The incidence of comorbidities was evaluated during LTP with AA or TXA versus patients without LTP. RESULTS: A total of 446 patients were studied. A greater prevalence among patients was found for heart diseases (9.6% vs 4.8%), acute myocardial infarction (5.6% vs 1.4%), hepatitis C virus infection (10.5% vs 2.5%), and appendectomy (15.9% vs 4.3%). In patients taking AA, a greater incidence was found for hypertension (22.8% vs 10.8%; odds ratio [OR]: 2.02), hypercholesterolemia (19.5% vs 5.3%; OR: 3.97), diabetes mellitus (5% vs 1.4%; OR: 3.21), hepatic angioma (4.4% vs 0.7%; OR: 8.35), and focal nodular hyperplasia (2.5% vs 0.4%; OR: 6.9). No association between TXA and comorbidities was found. CONCLUSION: In this large patient population with a rare disease followed for up to a 43-year period, we found a greater prevalence of comorbidities hitherto unreported in the literature and an association between comorbidities and LTP with AA.

RESUMEN

Acquired hemophilia A (AHA) is a rare bleeding disorder (1.4 per million inhabitants per year) caused by neutralizing antibodies against factor VIII. Although uncommon, these autoantibodies can cause a high rate of morbidity and mortality. Several conditions are linked with AHA; based on an EACH2 study, 3.8% of AHA could be connected to infection. In the last four years, most humans have contracted the SARS-CoV-2 infection or have been vaccinated against it. Whether or not COVID-19 immunization might induce AHA remains controversial. This review aims to evaluate the evidence about this possible association. Overall, 18 manuscripts (2 case series and 16 case reports) were included. The anti-SARS-CoV-2 vaccination, as also happens with other vaccines, may stimulate an autoimmune response. However, older individuals with various comorbidities are both at risk of developing AHA and of COVID-19-related morbidity and mortality. Therefore, the COVID-19 vaccine must always be administered because the benefits still outweigh the risks. Yet, we should consider the rare possibility that the activation of an immunological response through vaccination may result in AHA. Detailed registries and prospective studies would be necessary to analyze this post-vaccine acquired bleeding disorder, looking for possible markers and underlying risk factors for developing the disease in association with vaccination.

RESUMEN

Background: Parry-Romberg syndrome (PRS) is a rare craniofacial disorder. The aim of this study is to provide information on the immunological profile of this pathology. Since PRS can be included in a wider spectrum of sclerodermic diseases, we propose a case-control study comparing a patient affected by PRS with one with a diagnosis of scleroderma, herein used as control (CTR). Methods: B lymphocyte, T lymphocyte, and monocyte phenotypes and functions were assessed by flow cytometry in influenza (Flu)- or anti cluster differentiation (CD)3/CD28-stimulated peripheral blood mononuclear cells (PBMCs). Cytokine concentration was evaluated as well in PBMC supernatants, plasma, and saliva by Luminex assay. Results: T and B lymphocytes were similarly activated in unstimulated PRS and CTR cells but differed following antigen stimulation. T helper (Th)17 lymphocytes were expanded in PRS compared to CTR; this increase correlated with higher interleukin (IL)-17 concentration. Conclusions: Our case-control study is the first to compare the immunological profiles of PRS and scleroderma patients. The higher percentage of Th17 cells in PRS suggests the use of anti-IL17 receptor monoclonal antibody in this rare disease; however, further studies with larger numbers of patients are needed to confirm our findings.

RESUMEN

Polycystic ovary syndrome (PCOS) is the most common endocrine disorder in women during the fertile period. Women with PCOS have an increased risk of developing major cardiovascular risk factors during the fertile period: obesity, impaired glucose tolerance, diabetes mellitus, dyslipidemia, and metabolic syndrome. The possible effect of PCOS on cardiovascular disease (CVD) has been reported in different studies, but the results are not clear for several reasons. Indeed, most of the studies analyzed a cohort of fertile women who, given their relatively young age, have a low frequency of cardiovascular diseases. In addition, longitudinal studies have a short follow-up period, insufficient to draw firm conclusions on this topic. Finally, pharmacological treatment is limited by the lack of specific drugs available to specifically treat PCOS. In this review, we report on studies that analyzed the possible effect of PCOS on the most common CVD (hypertension, arterial stiffness, atherosclerosis, and cardiovascular event) and available drugs used to reduce CVD in PCOS women.

RESUMEN

BACKGROUND: Short peripheral catheters (SPCs) are used to provide intravenous therapies in hospitalized patients. Recently, the category of SPC has become more complex, with the introduction in clinical practice of "integrated" SPCs (ISPCs), renewed regarding the material (polyurethane rather than polytetrafluoroethylene) and design (large wing; pre-assembled extension; preassembled needle-free connector (NFC)). METHODS: This systematic review and meta-analysis aimed to analyze randomized controlled trials (RCTs) and quasi-randomized studies in hospitalized patients, analyzing the risk of overall catheter failure as well as the risk of each type of complication (occlusion, infiltration, thrombophlebitis, and dislodgement) for ISPCs compared to non-integrated SPCs. These systematic review and meta-analysis were registered on PROSPERO (CRD42022322970). DATA SOURCES: We searched PUBMED®, EMBASE®, and the Cochrane Controlled Clinical Trials register from April to November 2022. RESULTS: INCLUDED STUDIES: The research identified 1260 articles. After the abstract review, 13 studies were included for full manuscript review and, after that, six papers (4727 patients) were included in the meta-analysis. DESCRIPTION OF THE EFFECT: We found a significantly reduced risk of catheter failure (pooling all complications) for ISPCs compared to SPCs (p = 0.002 RR 0.65; 95% CI 0.63-0.9). A significant reduction in the risks of occlusion (p = 0.007 RR 0.72; 95% CI 0.56-0.92) was observed. As regards the risk of infiltration, thrombophlebitis, and dislodgement, the analysis showed a trend in favor of ISPCs, though not statistically significant (respectively p = 0.2 RR 0.84; 95% CI 0.64-1.1; p = 0.25 RR 0.91; 95% CI 0.78-1.07; p = 0.06 RR 0.72; 95% CI 0.52-1.01). CONCLUSIONS: ISPCs significantly reduce the risks of catheter failure (overall complications) and occlusion. More RCTs are needed to understand if the preassembled ISPC is better than the composted closed system (non-integrated SPC + extension line + NFC).

RESUMEN

INTRODUCTION: Short peripheral catheters (SPCs) are affected by a high complication rate that leads to catheter failure. Currently, the Visual Infusion Phlebitis score (VIP) is the most used tool to verify the presence of inflammatory complications (phlebitis and thrombophlebitis). However, ultrasound signs (US) may be an attractive alternative. OBJECTIVE: This study aims to evaluate the sensitivity and specificity of US and VIP score = 1 in identifying and recognizing early signs of SPC failure. The time to positivity for US and VIP scores was assessed as a secondary outcome. METHODS: An observational prospective study was conducted. In each patient, US (subcutaneous edema; fibroblastic sleeve; thrombophlebitis) and VIP of the exit site were performed every 24 h until 96 h after insertion. Compared to catheter failure, Sensitivity, Specificity, and Predictive values in both US and VIP were calculated. RESULTS: Two hundred patients were enrolled. The presence of ultrasonic pattern suggestive of edema at 72 h (p = 0.018), fibroblastic sleeve at 24, 48, 72, and 96 h (p < 0.001), thrombosis at 48 (p < 0.001) and 72 h (p = 0.005), and at least one of an abovementioned US at all checkpoints (p < 0.001) were highly significant predictors of complications. Both US and VIP effectively detect inflammatory events; however, the US showed better sensitivity in overall checkpoints and earlier predictive ability than VIP (1.9 vs 0.47 days). CONCLUSIONS: An ultrasound inflammatory pattern is correlated with SPC failure. An ultrasound protocol-requiring minimal training-is more effective than VIP in recognizing early signs of device failure.

RESUMEN

BACKGROUND: Myeloproliferative neoplasms (MPNs) are often associated with splanchnic vein thrombosis (SVT). Not all the factors involved in the thrombotic tendency are currently known. OBJECTIVES: This study aims to evaluate a possible association between ADAMTS13, von Willebrand factor (VWF), platelet microvesicles (MV), and factor VIII activity (FVIII:C) with thrombotic events in MPN patients. MATERIALS AND METHODS: In total, 36 consecutive MPN patients with SVT were enrolled. The MPNs were diagnosed based on clinical characteristics and one or more gene mutations among JAK-2, CALR, and MPL. As controls, 50 randomly selected patients with MPN without thrombosis, 50 patients with deep vein thrombosis without MPNs, and 50 healthy blood donors were evaluated. Complete blood count, ADAMTS13, VWF, MV, and FVIII:C in plasma were measured in all the subjects. RESULTS: The JAK-2 mutation was found in 94% of the patients with SVT, but none were triple-negative for genetic mutations (JAK2 V617F, CALR, MPL, and exon 12). Compared to the normal subjects, in all the MPN patients (with or without SVT), the levels of ADAMTS13 were found to be significantly lower (p < 0.001) and the MV concentrations were significantly higher (p < 0.001). Among the MPN patients, the VWF and FVIII:C levels were significantly higher in the patients with SVT than those without thrombosis (p = 0.007 and p = 0.04, respectively). Splenomegaly was present in 78% of MPN patients with SVT and in 30% of those without SVT (p < 0.001). The ADAMTS13/VWF ratio was reduced in all the patients, but not in the healthy blood donors (p < 0.001). CONCLUSIONS: The significant increase in circulating MV, VWF, and FVIII:C in the MPN patients and in the patients with thrombosis supports the role of endothelium damage in promoting thrombotic events. In particular, a significant increase in VWF and FVIII:C levels was found in the MPN patients with SVT.

RESUMEN

INTRODUCTION: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

RESUMEN

INTRODUCTION: Situations involving increased workloads and stress (i.e., the COVID-19 pandemic) underline the need for healthcare professionals to minimize patient complications. In the field of vascular access, tunneling techniques are a possible solution. This systematic review and meta-analysis aimed to compare the effectiveness of tunneled Peripherally Inserted Central Catheters (tPICCs) to conventional Peripherally Inserted Central Catheters (cPICCs) in terms of bleeding, overall success, procedural time, and late complications. METHODS: Randomized controlled trials without language restrictions were searched using PUBMED®, EMBASE®, EBSCO®, CINAHL®, and the Cochrane Controlled Clinical Trials Register from August 2022 to August 2023. Five relevant papers (1238 patients) were included. RESULTS: There were no significant differences in overall success and nerve or artery injuries between the two groups (p = 0.62 and p = 0.62, respectively), although cPICCs caused slightly less bleeding (0.23 mL) and had shorter procedural times (2.95 min). On the other hand, tPICCs had a significantly reduced risk of overall complications (p < 0.001; RR0.41 [0.31-0.54] CI 95%), catheter-related thrombosis (p < 0.001; RR0.35 [0.20-0.59] IC 95%), infection-triggering catheter removal (p < 0.001; RR0.33 [0.18-0.61] IC 95%), wound oozing (p < 0.001; RR0.49 [0.37-0.64] IC 95%), and dislodgement (p < 0.001; RR0.4 [0.31-0.54] CI 95%). CONCLUSIONS: The tunneling technique for brachial access appears to be safe concerning intra-procedural bleeding, overall success, and procedural time, and it is effective in reducing the risk of late complications associated with catheterization.

RESUMEN

BACKGROUND: Long peripheral catheters (LPCs) role in Difficult IntraVenous Access (DIVA) patients admitted to the emergency department has already been studied, resulting in a rapid, safe, and cost-effective procedure. Although their use in outpatient settings is established, there is a lack of studies assessing their benefits. In particular, rheumatologic outpatients affected by scleroderma, especially those affected by digital ulcers, are often treated with intravenous infusions of prostaglandin I2 (PGI2) analog (IV-PGI2A). OBJECTIVE AND METHODS: From 1 October 2021 to 31 March 2024, we conducted a prospective study enrolling DIVA outpatients affected by systemic sclerosis or undifferentiated connective tissue disease who needed IV-PGI2A therapy at L. Sacco Hospital in Milan (Italy). Each treatment cycle consisted of four consecutive days of infusion of iloprost or alprostadil. The primary aim was to assess the efficacy and potential complications associated with LPCs for IV-PGI2A. RESULTS: Twenty-six patients were enrolled 23 were females (88.5%), and the median age was 72 years (IQR 56-78.7). In total, 97 LPCs were inserted, with a mean number of insertions per patient/year of 2.3. An increase in LPCs insertion during the 30 months of the enrollment period was observed. Eighteen patients required more than one LPC placement, and in 61% of them, the second venipuncture was executed at a different site. No procedural complications were registered (accidental puncture of the brachial artery, accidental median nerve puncture, bleeding) nor late complications (Catheter-Related Thrombosis, Catheter-Related Bloodstream Infections, Accidental Removal). CONCLUSIONS: Our experience shows that LPCs could be valuable and safe for rheumatologic outpatients. The increased number of insertions and new and total patients enrolled each year defines the satisfaction of patients and health care professionals.

RESUMEN

Central venous access devices are essential for the management of critically ill patients, but they are potentially associated with many complications, which may occur during or after insertion. Many evidence-based documents-consensus and guidelines-suggest practical recommendations for reducing catheter-related complications, but they have some limitations. Some documents are not focused on critically ill patients; other documents address only some special strategies, such as the use of ultrasound; other documents are biased by obsolete concepts, inappropriate terminology, and lack of considerations for new technologies and new methods. Thus, the Italian Group of Venous Access Devices (GAVeCeLT) has decided to offer an updated compendium of the main strategies-old and new-that should be adopted for minimizing catheter-related complications in the adult critically ill patient. The project has been planned as a consensus, rather than a guideline, since many issues in this field are relatively recent, and few high-quality randomized clinical studies are currently available, particularly in the area of indications and choice of the device. Panelists were chosen between the Italian vascular access experts who had published papers on peer-reviewed journals about this topic in the last few years. The consensus process was carried out according to the RAND/University of California at Los Angeles (UCLA) Appropriateness Methodology, a modification of the Delphi method, that is, a structured process for collecting knowledge from groups of experts through a series of questionnaires. The final document has been structured as statements which answer to four major sets of questions regarding central venous access in the critically ill: (1) before insertion (seven questions), (2) during insertion (eight questions), (3) after insertion (three questions), and (4) at removal (three questions).
