Background. The amount of hepatology-related information available on the Internet has substantially increased, but little is known about the characteristics and quality of the websites. Aim. The aim of this study was to describe analytically and evaluate critically the information concerning three diseases of hepatological interest: chronic hepatitis, hemochromatosis and Caroli’s disease. Methods. In accordance with a validated method, the three search terms were entered into four English language search engines and the first five links of each were considered (a total of 60 sites). The characteristics of the websites were described and their quality was evaluated by three independent reviewers who assigned scores of 1–5 for accuracy, reliability and depth. The relationships between the site characteristics and quality scores were analysed by means of multiple logistic regression. Results. The overall rating score was sufficient (≥3) in 51% (95% confidence interval: 38–65%) of cases. The majority of the sites (73%) were aimed at patients rather than at physicians. Commercial sponsorship was significantly more frequent among the chronic hepatitis sites (45%) than among the hemochromatosis (15%) or Caroli’s disease sites (0%) (P=0.002); 61% of the commercial sites did not include a financial disclosure. The only variable that independently related to poor quality was the presence of commercial sponsorship (odds ratio 18.1; 95% confidence interval: 1.7–192.5). Conclusions. Hepatological websites are characterised by poor quality and are mainly aimed at patients. Quality is negatively affected by commercial interests, which are often undeclared. Guidelines for the certification and surveillance of websites relating to liver diseases are highly advisable.

Purpose: To estimate cancer screening coverage among a large sample of Greek individuals. Methods: 7012 adults from 30 Hellenic areas were surveyed. Tests included: faecal occult blood test, sigmoidoscopy, chest X-ray, urine test, testicular examination, trans-rectal ultrasound, full blood count, skin examination, digital rectal examination, PSA, Pap test, mammography, clinical breast examination (CBE), self breast examination and breast ultrasound. Results: Eighty-eight percent of males and 93% of females declared being interested in cancer screening; 37.8% of men and 37.9% of women had had a medical consultation for screening purpose in the previous 2 years. Less than 2% reported having received screening for colorectal cancer or skin malignancies. Screening for cervical cancer, mammography and CBE was reported by 39.6%, 22.8% and 27.9% of females respectively. Twenty percent of males reported screening for prostate cancer. Conclusion: The actual opportunistic screening approach presents important deficiencies with displaced priorities in test performance and a low proportion of individuals undergoing recommended tests. © Feseo 2009. 11 4 228 236

Eventos adversos; Arritmia; Resultados Adverse events; Arrhythmia; Outcomes Esdeveniments adversos; Arítmia; Resultats Background and Objectives: Knowledge of the incidence and time frames of the adverse events of patients presenting syncope at the ED is essential for developing effective management strategies. The aim of the present study was to perform a meta-analysis of the incidence and time frames of adverse events of syncope patients. Materials and Methods: We combined individual patients’ data from prospective observational studies including adult patients who presented syncope at the ED. We assessed the pooled rate of adverse events at 24 h, 72 h, 7–10 days, 1 month and 1 year after ED evaluation. Results: We included nine studies that enrolled 12,269 patients. The mean age varied between 53 and 73 years, with 42% to 57% females. The pooled rate of adverse events was 5.1% (95% CI 3.4% to 7.7%) at 24 h, 7.0% (95% CI 4.9% to 9.9%) at 72 h, 8.4% (95% CI 6.2% to 11.3%) at 7–10 days, 10.3% (95% CI 7.8% to 13.3%) at 1 month and 21.3% (95% CI 15.8% to 28.0%) at 1 year. The pooled death rate was 0.2% (95% CI 0.1% to 0.5%) at 24 h, 0.3% (95% CI 0.1% to 0.7%) at 72 h, 0.5% (95% CI 0.3% to 0.9%) at 7–10 days, 1% (95% CI 0.6% to 1.7%) at 1 month and 5.9% (95% CI 4.5% to 7.7%) at 1 year. The most common adverse event was arrhythmia, for which its rate was 3.1% (95% CI 2.0% to 4.9%) at 24 h, 4.8% (95% CI 3.5% to 6.7%) at 72 h, 5.8% (95% CI 4.2% to 7.9%) at 7–10 days, 6.9% (95% CI 5.3% to 9.1%) at 1 month and 9.9% (95% CI 5.5% to 17) at 1 year. Ventricular arrhythmia was rare. Conclusions: The risk of death or life-threatening adverse event is rare in patients presenting syncope at the ED. The most common adverse events are brady and supraventricular arrhythmias, which occur during the first 3 days. Prolonged ECG monitoring in the ED in a short stay unit with ECG monitoring facilities may, therefore, be beneficial. This research received no external funding.

Background There has been a noticeable annual increase in the number of children coming to Italy for medical treatment, just like it has happened in the rest of the European Union. In Italy, the assistance to children suffering from cancer is assured by the current network of 54 centres members of the Italian Association of Paediatric Haematology and Oncology (AIEOP), which has kept records of all demographic and clinical data in the database of Mod.1.01 Registry since 1989. Methods We used the information stored in the already mentioned database to assess the impact of immigration of foreign children with cancer on centres' activity, with the scope of drawing a map of the assistance to these cases. Results Out of 14,738 cases recorded by all centres in the period from 1999 to 2008, 92.2% were born and resident in Italy, 4.1% (608) were born abroad and living abroad and 3.7% (538) were born abroad and living in Italy. Foreign children cases have increased over the years from 2.5% in 1999 to. 8.1% in 2008. Most immigrant children came from Europe (65.7%), whereas patients who came from America, Asia and Oceania amounted to 13.2%, 10.1%, 0.2%, respectively. The immigrant survival rate was lower compared to that of children who were born in Italy. This is especially true for acute lymphoblastic leukaemia patients entered an AIEOP protocol, who showed a 10-years survival rate of 71.0% vs. 80.7% (p < 0.001) for immigrants and patients born in Italy, respectively. Conclusions Children and adolescents are an increasingly important part of the immigration phenomenon, which occurs in many parts of the world. In Italy the vast majority of children affected by malignancies are treated in AIEOP centres. Since immigrant children are predominantly treated in northern Italy, these centres have developed a special expertise in treating immigrant patients, which is certainly very useful for the entire AIEOP network.

BACKGROUND The anti-tumour necrosis factor (TNF)-α adalimumab is the only licenced biologic for moderate-to-severe hidradenitis suppurativa (HS). No predictors of response have been identified so far. OBJECTIVES To identify clinical parameters predicting response to adalimumab and confirm its efficacy/safety. METHODS The data of 389 patients with HS treated with adalimumab in 21 Italian centres were reviewed. Sex, age at onset/diagnosis/baseline, body mass index, smoking, phenotype, previous treatments, concomitant antibiotics and 'therapeutic delay', defined as the time from HS onset to adalimumab initiation, were assessed. Response to adalimumab and its impact on quality of life (QoL) were evaluated using the Hidradenitis Suppurativa Clinical Response (HiSCR) and the Dermatology Life Quality Index (DLQI) or the Visual Analogue Scale for pain (VAS pain), respectively. Logistic regression analysis was performed. RESULTS The therapeutic delay correlated to lack of response to adalimumab at week 16 [odds ratio (OR) 1·92 for therapeutic delay > 10 years; 95% confidence interval (CI) 1·28-2·89; P = 0·0016). HiSCR was achieved in 43·7% and 53·9% patients at week 16 and 52, respectively. Significant reductions in both DLQI and VAS pain were found between week 16 vs. baseline (P < 0·0001 for both) and week 52 vs. baseline (P < 0·0001 for both). Previous immunosuppressants inversely correlated to HiSCR at week 52 (OR = 1·74, 95% CI 1·04-2·91, P = 0·0342). CONCLUSIONS Inverse correlation between therapeutic delay and clinical response was found, supporting early adalimumab use and providing evidence for a 'window of opportunity' in HS treatment. Adalimumab efficacy and safety were confirmed, along with patients' QoL improvement. Immunosuppressants could negatively influence the response to adalimumab inducing a switch to non-TNF-α-driven pathways.

Background COVID-19 is associated with a wide range of skin manifestations. Objective To describe the clinical characteristics of COVID-19-associated skin manifestations, and explore the relationships between the six main cutaneous phenotypes and systemic findings. Methods Twenty-one Italian Dermatology Units were asked to collect the demographic, clinical and histopathological data of 200 patients with COVID-19-associated skin manifestations. The severity of COVID-19 was classified as asymptomatic, mild, moderate, or severe. Results A chilblain-like acral pattern significantly associated with a younger age (p, There are six main COVID-19-related cutaneous phenotypes, but only the chilblain-like acral pattern significantly associated with younger age. After adjusting for patient age, there was no spectrum of COVID-19 severity in relation to cutaneous phenotypes, although the longer-lasting chilblain-like acral pattern significantly associated with milder disease.

Background and Aims Lupus Nephritis (LN) is the organ manifestation with the most severe prognosis in Systemic Lupus Erythematosus (SLE). Treatment options are limited due to partial efficacy, intolerance or side effects; moreover 10% of patients reach ESRD despite treatments. Rituximab (RTX) in LN is recommended as second line drug for induction of the remission after failure of Cyclophosphimide or Mycophenolate Mofetil. We have shown a role for RTX as maintenance therapy (RMT) in SLE however the effects of such approach on LN are still unclear. Aim of this study was a sub-analyses of a cohort of SLE patients treated with RTX focusing on the ones with active LN at the moment of the first RTX administration. Methods Patients with active LN at the time of the first RTX administration within a cohort of 147 patients with SLE were identified. Patients with SLE and a flare of LN were classified as treated with a “Single RTX course” (any RTX regimen administered within a single month) (SRC) or with RMT. Patients receiving at least three SRCs with the aim of relapse prevention and within 4 to 8 months between consecutive treatments, were classified as receiving RMT. LN activity was determined according to creatinine, proteinuria and haematuria; complete response (CR) was defined as a decrease of proteinuria to 30% or the detection of an active urinary sediment due, according to the treating physician, to active disease. Results 33 patients were identified; a renal biopsy had been performed in 76% with prevalence of class IV lupus nephritis in 16/33 (48%). Six months after RTX the rate of CR, PR and TF was respectively 36%, 27% and 36%; proteinuria and the prednisolone dose reduced significantly compared to baseline (respectively from a median of 2200 mg/day (IQR 499-5400) to 850 mg/day (IQR 400-1700) (p=0.005)) and from 25 mg (IQR 11-25) to 10 mg (IQR 6.125-15) (p Of the 33 patients, 11 received RMT with a median duration of 18 months (IQR 12,6-23,4) and a median RTX dose of 5 g (IQR 4-6). During the RMT 3 patients experienced a renal flare. The median follow-up after the last RTX administration within the SRC and the RMT groups was respectively 15 months (IQR 13,5-18,4) and 16 months (IQR 3,5-23). Comparing the RF free-survival of the two subgroups after the last RTX infusion, there was a trend towards a longer relapse free survival after the RMT (p=0.057) (figure, left panel). Of interest, the renal relapse free-survival of the 11 patients treated with RMT after the last RTX infusion was significantly longer compared to the one of the same group after the first RTX (p=0.0271) (figure, right panel). The incidence of SAEs per 100 patient years was 0.31 in the SRC group and 0.74 in the RMT group. Conclusion RTX is confirmed as an effective option for patients with LN. A RMT may have a role in improving LN disease control compared to a single RTX administration.

Background and Aims Idiopathic Focal Segmental Glomerulosclerosis (FSGS) is a rare glomerulonephritis often complicated by a chronic relapsing course frequently characterized by dependency or resistance to immunosuppressive treatment. Moreover, about half of the patients with active disease would develop end-stage renal disease within 10 years from the diagnosis, highlighting the need of novel therapeutic approaches. Rituximab (RTX), a chimeric monoclonal antibody against CD20, showed promising results in pediatric steroid-dependent/frequently relapsing FSGS and in post-transplantation recurrence. However, evidence about its role in the FSGS of the adult is still lacking with small case series suggesting conflicting results. In this study we assess the efficacy of RTX in the largest cohort of adults with FSGS currently available in literature. Methods Adults with biopsy proven idiopathic FSGS treated with RTX were retrospectively identified among several Italian nephrology units. Response to RTX was evaluated at 3, 6, 12 months and, when available, during the long-term follow-up. A positive response (POR) was defined as: (1) proteinuria 50% compared to baseline, (2) stable renal function (3) decreased or stable dose of glucocorticoids and other immunosuppressants. Severe Adverse Events (SAEs) have been recorded. Results 31 patients have been identified: 18 steroid-dependent, 11 steroid-resistant, and 2 patients with major contraindication to steroid therapy. RTX has been administered at a median of 87 months (IQR 54–96) from the diagnoses using heterogeneous schedules of administration. Overall, the POR rate at 6 months was 52% (steroid-dependent=69%; steroid-resistant=22%). At univariate analyses, POR to RTX at 6 months was associated to the steroid-dependent status (p=0.0347) and a proteinuria at RTX Conclusion RTX may be an option in the FSGS of the adult, especially in the steroid-dependent patients and the ones with less severe nephrotic syndrome. In the responders, a RTX based maintenance therapy may be required.

Introduction Advances in paediatric oncology led to the increase in long-term survival, revealing the burden of therapy-related long-term side effects. We evaluated overall and cause-specific mortality in a large cohort of Italian childhood cancer survivors (CCSs) and adolescent cancer survivors identified through the off-therapy registry. Materials and methods CCSs alive 5 years after cancer diagnosis occurring between 1960 and 1999 were eligible; the last follow-up was between 2011 and 2014. Outcomes were reported as standardised mortality ratios (SMRs) and absolute excess risks (AERs). Results Among 12,214 CCSs, 1113 (9.1%) deaths occurred. Survival at 35 years since diagnosis was 87% (95% confidence interval [CI]: 86–88) and at 45 years was 81% (95% CI: 77–84). CCSs had an 11-fold increased risk of death (SMR 95% CI: 10.7–12), corresponding to an AER of 48 (95% CI: 45–51). Mortality decreased by 60% for survivors treated most recently (1990–1999). The most frequent causes of death were recurrence of the original cancer (56%), a subsequent neoplasm (19%) and cardiovascular diseases (5.8%). Among those who survived at least 15 years after diagnosis, a secondary malignancy was the leading cause of death. Conclusions This study confirms the impact of recent advances in anticancer therapy in reducing mortality, mainly attributable to recurrence but also to other causes. However, overall mortality continues to be higher than in the general population. A long-term follow-up is needed to prevent late mortality due to secondary neoplasms and non-neoplastic causes in CCSs.

Objective The efficacy of rituximab (RTX) in systemic lupus erythematosus (SLE) is a subject of debate. This study was undertaken to investigate the outcomes of RTX treatment in a European SLE cohort, with an emphasis on the role of RTX as a maintenance agent. Methods All patients with SLE who were receiving RTX as induction therapy in 4 centers were included. Patients who received a single course of RTX and those who received RTX maintenance treatment (RMT) were followed up after treatment. Disease flares during the follow-up period were defined as an increase in disease activity and the number or dose of immunosuppressive drugs. Results Of 147 patients, 27% experienced treatment failure at 6 months. In a multivariate analysis, a low number of previous immunosuppressive therapies (P = 0.034) and low C4 levels (P = 0.008) reduced the risk of treatment failure. Eighty patients received RMT over a median of 24.5 months during which 85 relapses, mainly musculoskeletal, were recorded (1.06 per patient). At the time of the last RTX course, 84% of the patients were in remission. Twenty-eight (35%) of 80 patients never experienced a flare during RMT and had low damage accrual. Active articular disease at the time of the first RTX administration was associated with a risk of flare during RMT (P = 0.011). After RMT, relapse-free survival was similar to that in patients receiving a single RTX course (P = 0.72). Conclusion RMT is a potential treatment option for patients with difficult-to-treat disease. Relapses occur during RMT and are more likely in those with active articular disease at the time of the first RTX administration. Relapse risk after RMT remains high and apparently comparable to that seen after a single RTX course.

Traditionally, hematopoietic stem cell transplantation (HSCT) from both HLA-matched related and unrelated donors (UD) has been used for treating children with acute leukemia (AL) in need of an allograft. Recently, HLA-haploidentical HSCT after αβ T-cell/B-cell depletion (αβhaplo-HSCT) was shown to be effective in single-center studies. Here, we report the first multicenter retrospective analysis of 127 matched UD (MUD), 118 mismatched UD (MMUD), and 98 αβhaplo-HSCT recipients, transplanted between 2010 and 2015, in 13 Italian centers. All these AL children were transplanted in morphological remission after a myeloablative conditioning regimen. Graft failure occurred in 2% each of UD-HSCT and αβhaplo-HSCT groups. In MUD vs MMUD-HSCT recipients, the cumulative incidence of grade II to IV and grade III to IV acute graft-versus-host disease (GVHD) was 35% vs 44% and 6% vs 18%, respectively, compared with 16% and 0% in αβhaplo-HSCT recipients (P < .001). Children treated with αβhaplo-HSCT also had a significantly lower incidence of overall and extensive chronic GVHD (P < .01). Eight (6%) MUD, 32 (28%) MMUD, and 9 (9%) αβhaplo-HSCT patients died of transplant-related complications. With a median follow-up of 3.3 years, the 5-year probability of leukemia-free survival in the 3 groups was 67%, 55%, and 62%, respectively. In the 3 groups, chronic GVHD-free/relapse-free (GRFS) probability of survival was 61%, 34%, and 58%, respectively (P < .001). When compared with patients given MMUD-HSCT, αβhaplo-HSCT recipients had a lower cumulative incidence of nonrelapse mortality and a better GRFS (P < .001). These data indicate that αβhaplo-HSCT is a suitable therapeutic option for children with AL in need of transplantation, especially when an allele-matched UD is not available.

Introduction: Hepatocellular carcinoma (HCC) is a frequent complication in patients with chronic liver diseases and one of the most common malignancies worldwide. Liver resection is the gold standard treatment option for patients with solitary tumors; however, tumor recurrence complicates 70% of cases of hepatic resection at 5 years. Recently it has been demonstrated that the degree of portal hypertension (PH) measured by HVPG is directly correlated with the risk of developing HCC. We recently documented that spleen (SSM) and liver (LSM) stiffness measurement are accurate non-invasive markers of portal hypertension in cirrhosis. Aims: The aim of our study was to identify the role of SSM and LSM as predictors of HCC recurrence after curative resection. Materials and methods/Results: 157 patients with HCC who underwent curative resection between 2008 and 2014 were prospectively enrolled to assess early (24 months) recurrence. The results of LSM and SSM assessed with TE (Fibroscan®, Echosens) together with clinical and histological data were collected before surgery and their association with early or late recurrence was assessed by uni and multivariate logistic regression analysis. Forty-nine (49) patients with early and 22 with late HCC recurrence were identified during follow-up period. At univariate analysis, early recurrences were associated with etiology, number of nodules, HCC diameter and grading, infiltrated resection margins and satellitosis. Multivariate analysis showed that only viral (HCV, HBV) etiology, tumor diameter and margin infiltration were independently associated with early recurrence with an area under the curve (AUC) of 0.73. At univariate analysis late recurrence was associated only with SSM (p = 0.0027) with an AUC of 0.70. Conclusions: Early HCC recurrence is associated with HCC clinical and pathological features; late recurrence was best predicted by the assessment of SSM, thus suggesting a role of portal hypertension in the development of HCC late recurrence.

The outcome of high-risk (HR) Acute Lymphoblastic Leukemia (ALL) patients enrolled in AIEOP-BFM ALL 2000 study (NCT00613457) in Italy is described. Overall, 1999 Philadelphia negative ALL patients entered the study. HR criteria were: minimal residual disease (MRD) levels ≥10-3 at day 78 (HR-MRD), no complete remission (no-CR) at day 33, t(4;11) translocation, Prednisone Poor Response (PPR). Treatment (2 years) included protocol I, 3 polychemotherapy blocks, delayed intensification (protocol IIx2 or IIIx3), cranial radiotherapy, maintenance. 312 HR patients (15.6% of the total) had 5-year event-free survival (EFS) and overall survival (OS) of 58.9%(SE 2.8) and 68.9%(2.6). In hierarchical order, EFS was 45.9%(4.4) in 132 HR-MRD patients, 41.2%(11.9) in 17 patients no-CR at day 33, 36.4%(14.5) in 11 patients with t(4;11), 74.0%(3.6) in 152 HR patients only for PPR. No statistically significant difference was found for disease-free survival (DFS) in patients with very high risk features (HR-MRD, no-CR at day 33, t(4;11) translocation), given HSCT (n=66) or chemotherapy only (n=88), after adjusting for waiting time to hematopoietic stem cell transplantation (HSCT) (5.7 months). Patients at HR only for PPR have favorable outcome. High risk MRD is associated with poor outcome despite intensive treatment and/or HSCT and may qualify for innovative therapies. The study is registered at the US National Institutes of Health website http://clinicaltrials.gov as "Combination Chemotherapy Based on Risk of Relapse in Treating Young Patients With Acute Lymphoblastic Leukaemia" with the protocol identification number NCT00613457.

Background & Aims The hepatic vein pressure gradient (HVPG) is the standard used to determine the degree of portal hypertension (PH) and an important prognostic factor for patients with cirrhosis; HVPG values correlate with the presence of esophageal varices (EV). However, HVPG can only be accurately determined at specialized centers; noninvasive methods are needed to predict HVPG values and the presence of EV. We compared the diagnostic performance of spleen stiffness (SS) measurement by transient elastography with that of liver stiffness (LS) and of other recently proposed noninvasive tests. Methods We measured SS and LS in 100 consecutive patients with hepatitis C virus–induced cirrhosis. Patients were also assessed by FibroScan, HVPG, esophagogastroduodenoscopy, and liver biopsy. We also analyzed LS–spleen diameter to platelet ratio score and platelet count to spleen diameter. Results SS and LS were more accurate than other noninvasive parameters in identifying patients with EV and different degrees of PH. A linear model that included SS and LS accurately predicted HVPG values ( R 2 = 0.85). The results were internally validated using bootstrap analysis. Conclusions Measurement of SS can be used for noninvasive assessment and monitoring of PH and to detect EV in patients with hepatitis C virus–induced cirrhosis.

The management of congenital and acquired neutropenias presents some differences according to the type of the disease. Treatment with recombinant human granulocyte-colony stimulating factor (G-CSF) is not standardized and scanty data are available on the best schedule to apply. The frequency and the type of longitudinal controls in patients affected with neutropenias are not usually discussed in the literature. The Neutropenia Committee of the Marrow Failure Syndrome Group (MFSG) of the Associazione Italiana di Emato-Oncologia Pediatrica (AIEOP) elaborated this document following design and methodology formerly approved by the AIEOP board. The panel of experts reviewed the literature on the topic and participated in a conference producing a document that includes recommendations on neutropenia treatment and timing of follow-up. © 2011 Wiley Periodicals, Inc.

Background We evaluated an intensified chemotherapy strategy in children with Wilms tumor who relapsed with high-risk features. Procedures From January 2001 to June 2006, we treated 20 consecutive children with reinduction chemotherapy (using ifosfamide/carboplatin/etoposide in 15/20 cases), with (n = 15) or without (n = 5) subsequent high-dose chemotherapy and hematopoietic stem cell support, surgery where feasible, and radiation therapy. The median time to relapse was 10 months after nephrectomy. All but two children initially received doxorubicin as first-line therapy. Results All patients were assessed for outcome: 13 are currently alive, 12 of them in remission a median 25 months since their relapse, one with progressing tumor. The treatment was unsuccessful in eight children: the disease progressed during reinduction in three, and relapsed in five. There was one toxic death. All transplanted patients engrafted to a neutrophil count >0.5 × 103/µl after a median 11 days, and to an unsustained platelet count >25,000/µl after a median of 13 days. Three-year disease-free and overall survival rates were 56 ± 12% and 55 ± 13%, respectively. Neither recurrence within 12 months of nephrectomy nor extra-lung recurrence negatively affected outcome. A survival advantage was demonstrated in patients without disease evidence prior to transplant. Conclusion A disease-free survival rate nearing 50% is a realistic target in children with high-risk recurrent Wilms tumor. The benefit of autologous hematopoietic stem cell transplantation for consolidation deserves to be investigated in a randomized, controlled study.

Background Alterations of cardiac autonomic control (CAC) are associated with poor outcomes in patients with infectious and non-infectious diseases. No evaluation of CAC in patients with community-acquired pneumonia (CAP) has been performed so far. The aim of the study was to assess CAC in patients with CAP and evaluate the impact of its alterations on disease severity and clinical outcomes in a multicenter, prospective, observational study. Methods Consecutive patients hospitalized for CAP were enrolled between 2011 and 2013 two university hospitals in Italy. CAC was assessed by linear spectral and non-linear symbolic analysis of heart rate variability. The presence of severe CAP was evaluated on hospital admission. The primary study outcome was time to clinical stability (TCS) during hospitalization. Results Among the 75 patients enrolled (median age: 75 years; 57 % males), a significantly lower total variability and reduction of sympathetic rhythmical component with predominant respiratory modulation was detected in comparison to controls. Among CAP patients affected by a severe CAP on admission, CAC showed a lower sympathetic modulation and predominant parasympathetic oscillatory rhythm. At the multivariate analysis, variables independently correlated with a TCS >7 days were total power, as marker of total variability, [OR (95 % CI): 0.997 (0.994–1.000), p = 0.0454] and sympathetic modulation [OR (95 % CI): 0.964 (0.932–0.998), p = 0.0367]. Conclusions Loss of sympathetic rhythmical oscillation is associated with a more severe disease and worse early clinical outcome in hospitalized patients with CAP.
