RESUMO

BACKGROUND: While growing literature is stressing the link between Autistic Traits (AT) and trauma-/stress-related disorders, in both conditions significant differences have been separately reported. OBJECTIVE: This study aims to evaluate the relationship between AT and trauma-/stress-related symptoms with respect to sex. METHODS: 178 university students were assessed with the Structured Clinical Interview for DSM-5, the Trauma and Loss Spectrum (TALS) and the Adult Autism Subthreshold Spectrum (AdAS). In order to evaluate sex differences in trauma-/stress-related symptoms among subjects with higher or lower AT, the sample was split in two groups with an equal number of subjects on the basis of the median score reported on AdAS Spectrum ("AdAS high scorers" and "AdAS low scorers"). RESULTS: Females reported significantly higher TALS total score, Loss events and Grief reaction domain scores than males in the whole sample, while AdAS high scorers reported significantly higher TALS total and domain scores than AdAS low scorers. A significant interaction between high/low AdAS score and sex emerged for TALS domains, with females scoring significantly higher than males only among AdAS low scorers, specifically on Loss events, Grief reaction, Re-experiencing and Personal characteristics/Risk factors domains. Finally, among AdAS high scorers a significantly higher rate of subjects fulfilled symptomatological criteria for PTSD than among AdAS low scorers, without sex differences. CONCLUSION: Our results confirm a significant relationship between AT and trauma-/stress-related symptoms, which seems to prevail on sex differences among high-risk subjects.

RESUMO

BACKGROUND AND PURPOSE: Proteinuria and estimated glomerular filtration rate (eGFR) are indicators of renal function. Whether proteinuria better predicts outcome than eGFR in stroke patients treated with intravenous thrombolysis (IVT) remains to be determined. METHODS: In this explorative multicenter IVT register based study, the presence of urine dipstick proteinuria (yes/no), reduced eGFR (<60 ml/min/1.73 m2 ) and the coexistence of both with regard to (i) poor 3-month outcome (modified Rankin Scale score 3-6), (ii) death within 3 months and (iii) symptomatic intracranial hemorrhage (ECASS-II criteria) were compared. Unadjusted and adjusted odds ratios (ORs) with 95% confidence intervals were calculated. RESULTS: Amongst 3398 patients, 881 (26.1%) had proteinuria and 623 (18.3%) reduced eGFR. Proteinuria [ORadjusted 1.65 (1.37-2.00) and ORadjusted 1.52 (1.24-1.88)] and reduced eGFR [ORadjusted 1.26 (1.01-1.57) and ORadjusted 1.34 (1.06-1.69)] were independently associated with poor functional outcome and death, respectively. After adding both renal markers to the models, proteinuria [ORadjusted+eGFR 1.59 (1.31-1.93)] still predicted poor outcome whilst reduced eGFR [ORadjusted+proteinuria 1.20 (0.96-1.50)] did not. Proteinuria was associated with symptomatic intracranial hemorrhage [ORadjusted 1.54 (1.09-2.17)] but not reduced eGFR [ORadjusted 0.96 (0.63-1.62)]. In 234 (6.9%) patients, proteinuria and reduced eGFR were coexistent. Such patients were at the highest risk of poor outcome [ORadjusted 2.16 (1.54-3.03)] and death [ORadjusted 2.55 (1.69-3.84)]. CONCLUSION: Proteinuria and reduced eGFR were each independently associated with poor outcome and death but the statistically strongest association appeared for proteinuria. Patients with coexistent proteinuria and reduced eGFR were at the highest risk of poor outcome and death.

RESUMO

OBJECTIVE: The aim of the present systematic review and meta-analysis was to evaluate the impact of physical exercise on cognitive symptoms in depressed adult patients. METHODS: Systematic literature search was performed in Web of Science™ and CINAHL from inception to August 2016. Two reviewers independently selected randomized trials evaluating the effect of exercise on cognitive functions in patients with a validated diagnosis of depression. Outcome measures included global cognition and different cognitive domains (speed of processing, attention/vigilance, working memory, verbal and visual memory, and reasoning). RESULTS: Eight trials met inclusion criteria (637 patients). A fixed-effects model showed absence of beneficial effect on global cognition (Hedges' g = 0.07, 95% CI -0.08 to 0.24, I2  = 0%) as well as on specific cognitive domains. Sensitivity analyses did not show an impact of exercise in studies with shorter intervention duration compared to longer trials (between group heterogeneity Q = 3.564, df = 1, P = 0.059), single session per week compared to multiple sessions (Q = 2.691, df = 1, P = 0.101) and low exercise intensity compared with moderate/high intensity (Q = 2.952, df = 1, P = 0.086). CONCLUSION: Our meta-analysis did not observe a substantial benefit of physical exercise on cognitive symptoms in depression.

RESUMO

We report the case of a patient with hereditary ceruloplasmin deficiency due to a novel gene mutation in ceruloplasmin gene (CP), treated with fresh frozen plasma (FFP) and iron chelation therapy. A 59-year-old man with a past history of diabetes was admitted to our department due to progressive gait difficulties and cognitive impairment. Neurological examination revealed a moderate cognitive decline, with mild extrapyramidal symptoms, ataxia, and myoclonus. Brain T2-weighted MR imaging showed bilateral basal ganglia hypointensity with diffuse iron deposition. Increased serum ferritin, low serum copper concentration, undetectable ceruloplasmin, and normal urinary copper excretion were found. The genetic analysis of the CP (OMIM #604290) reported compound heterozygosity for two mutations, namely c.848G > A and c.2689_2690delCT. Treatment with FFP (500 mL i.v./once a week) and administration of iron chelator (Deferoxamine 1000 mg i.v/die for 5 days, followed by Deferiprone 500 mg/die per os) were undertaken. At the 6-month follow-up, clinical improvement of gait instability, trunk ataxia, and myoclonus was observed; brain MRI scan showed no further progression of basal ganglia T2 hypointensity. This case report suggests that the early initiation of combined treatment with FFP and iron chelation may be useful to reduce the accumulation of iron in the central nervous system and to improve the neurological symptoms.

RESUMO

BACKGROUND AND PURPOSE: The impact of body mass index (BMI) on outcome in stroke patients treated with intravenous thrombolysis (IVT) was investigated. METHODS: In a multicentre IVT-register-based observational study, BMI with (i) poor 3-month outcome (i.e. modified Rankin Scale scores 3-6), (ii) death and (iii) symptomatic intracranial haemorrhage (sICH) based on criteria of the ECASS II trial was compared. BMI was used as a continuous and categorical variable distinguishing normal weight (reference group 18.5-24.9 kg/m2 ) from underweight (<18.5 kg/m2 ), overweight (25-29.9 kg/m2 ) and obese (≥30 kg/m2 ) patients. Univariable and multivariable regression analyses with adjustments for age and stroke severity were done and odds ratios with 95% confidence intervals [OR (95% CI)] were calculated. RESULTS: Of 1798 patients, 730 (40.6%) were normal weight, 55 (3.1%) were underweight, 717 (39.9%) overweight and 295 (16.4%) obese. Poor outcome occurred in 38.1% of normal weight patients and did not differ significantly from underweight (45.5%), overweight (36.1%) and obese (32.5%) patients. The same was true for death (9.5% vs. 14.5%, 9.6% and 7.5%) and sICH (3.9% vs. 5.5%, 4.3%, 2.7%). Neither in univariable nor in multivariable analyses did the risks of poor outcome, death or sICH differ significantly between BMI groups. BMI as a continuous variable was not associated with poor outcome, death or sICH in unadjusted [OR (95% CI) 0.99 (0.97-1.01), 0.98 (0.95-1.02), 0.98 (0.94-1.04)] or adjusted analyses [OR (95% CI) 1.01 (0.98-1.03), 0.99 (0.95-1.05), 1.01 (0.97-1.05)], respectively. CONCLUSION: In this largest study to date, investigating the impact of BMI in IVT-treated stroke patients, BMI had no prognostic meaning with regard to 3-month functional outcome, death or occurrence of sICH.

RESUMO

Cerebral amyloid angiopathy-related inflammation (CAA-ri) is a rare and treatable variant of CAA likely due to an autoimmune response directed toward beta-amyloid deposits. Cognitive and behavioral manifestations are the most common symptoms, followed by focal neurological signs, headache and seizures, associated with characteristics neuroradiological features on brain magnetic resonance imaging (MRI). We describe the clinical course, radiological features and therapeutic approach of two patients with probable CAA-ri with the aim of emphasizing the importance of an early diagnosis of this potentially reversible disease in different neurological settings, such as memory clinics and stroke units.

RESUMO

Close monitoring of estimated glomerular filtration rate (eGFR) is important for early recognition of worsening renal function to prevent further deterioration. Safe conversion from twice-daily tacrolimus (TD-Tac) to once-daily tacrolimus (OD-Tac) has been reported, but the effects on eGFR are contrasting. The aim of our study is to evaluate long-term stability of eGFR after 1:1 conversion from TD-Tac to OD-Tac and the effects on serum cytokine blood levels. Forty-six consecutive kidney transplant recipients treated with TD-Tac 3 to 5 years post-transplant, with stable renal function, were enrolled in the study (2009-2011). Clinical and biochemical parameters were evaluated for 12 months before conversion up to 6 years after conversion. The patients served as their own controls. A panel of cytokines was evaluated repeatedly during the first year after conversion. Mean values of eGFR were not different long-term after conversion (P = .11) compared with baseline, and the majority of patients remained stable on Kidney Disease: Improving Global Outcomes stage during the study period; eGFR was stable in 30.0% after 5 years, decreased > 1 mL/min/1.73 m2/y in 13.3%, and improved > 1 mL/min/1.73 m2/y in 56.7%. Cytokine levels and C-reactive protein did not show any significant deterioration. Metabolic parameters were stable during the 6 years of follow-up. OD-Tac therapy can preserve an effective immunosuppressive state together with a safe profile of eGFR.

RESUMO

BACKGROUND: Arterial vascular anomalies in patients undergoing kidney transplantation (KT) are correlated with a higher incidence of early surgical complications, potentially causing graft loss. Arterial reconstruction allows patients to overcome these surgical challenges, thus minimizing the risk of poor outcomes. The aim of the present study is to retrospectively investigate the safety and effectiveness of the multiple arterial reconstruction technique with a Teflon patch in case of an unavailable aortic patch: to do so, surgical complications, graft function, and patient survival were evaluated. METHODS: During the period January 2009 to August 2016, 202 adult deceased-donor KTs were performed at our center. Group A (n = 27; reconstruction of multiple arteries) and Group B (n = 175; control group) were compared. RESULTS: No differences were observed between the 2 groups in terms of early postoperative course, with no vascular complication observed in Group A. No vascular patch infections were reported, nor longer cold ischemia time rates. Similarly, long-term survival rates were similar between the 2 groups. CONCLUSIONS: The Teflon-patch arterial reconstruction technique appears to be safe and effective, with an acceptable balance of benefits and potential risks of using a prosthetic material. Studies based on larger series are needed to further validate this approach.

RESUMO

BACKGROUND: BK virus (BKV)-associated nephropathy is definitely involved in allograft failure after kidney transplant. Thus, the need for an early control of viral reactivation in immunocompromised patients is well established. Determination of urinary release of decoy cells (DC) and BK viral load in plasma and urine by polymerase chain reaction (PCR) usually precedes renal biopsy. The aim of the study is to assess viral reactivation by BKV-DNA PCR and DC detection in urinary sediment using automated intelligent microscopy. METHODS: Seventy-eight kidney transplant patients were analyzed for the presence of plasma BKV-DNA by quantitative TaqMan real-time PCR. Additionally, automated intelligent microscopy was used for urine sediment analysis, allowing to count cells with decoy feature, confirmed by phase contrast microscopic review. RESULTS: Plasma BKV-DNA PCR was detected in 14 (17.9%) patients. DC were identified in 19 (24.3%) urine sediments by automated analyzers and confirmed by microscopic observation. Two patients were BKV-DNA-positive/DC-negative; conversely, 7 subjects were DC-positive/BKV-DNA-negative. CONCLUSIONS: Plasma quantification of BK viral load is currently the best noninvasive method for the detection of viral reactivation. Nevertheless, automated methods to screen for the presence of DC in urine could facilitate early BK virus replication diagnosis and patient follow-up by quantitative and visual results.

RESUMO

Incidence of cardiovascular complications, cancers and chronic allograft nephropathy (CAN) suggests reduction of immunosuppressive dosages. Some studies analyzed the effects of minimization of immunosuppression until the avoidance of immunosuppressive drugs. However minimization seems to be related to a higher incidence of acute rejection. Induction of tolerance after transplantation and use of immunological tests that could monitor the immune reactivity are required. The aim of this study is to evaluate immunological state in a group of recipients after deceased and living donor kidney transplantation and to minimize immunosuppressive therapy monitoring simultaneously clinical and immunological parameters. We analyzed 41 patients, 38 from deceased donors and 3 from living donor kidney transplantation. All patients were treated with triple immunosuppressive therapy: cyclosporine or sirolimus or tacrolimus, mycophenolate mofetil and steroids. In all recipients the presence of CD8+CD28- T suppressor cells (Ts) was analyzed. Patients were divided in 2 groups, according to the presence of Ts. In patients with Ts, (Group A, n=19), mycophenolate mofetil (MMF) was progressively reduced and then stopped. Steroids were subsequently reduced and then interrupted, maintaining an immunosuppressive therapy with low doses of calcineurin inhibitors (CNI) or sirolimus (SIR). 22 patients were without presence of Ts: we enrolled for the study only patient acute rejection free, without proteinuria and with creatinine levels stable (Group B, n=19). In these patients, MMF was reduced and then stopped, while steroids were decreased to 5 mg at alternate days, maintaining CNI or SIR at medium therapeutic dosages (minimized therapy). Patient and graft overall survival in Group A and in Group B were respectively at 100% and 94.7%. Incidence of acute rejection was respectively at 0% in group A and 15.7% in Group B. Presence of episodes of acute rejection in Group B confirms risk of later minimization of steroids and the relevance of the analysis of recipient immunological reactivity before modification of immunosuppressive therapy. A careful evaluation of recipient immune reactivity with the presence of T regulatory cells can allow adequate and personalized immunosuppressive regimens, without high risks of acute rejection.

RESUMO

BACKGROUND: Patients with acute liver failure (ALF) show an aggravated hyperdynamic circulation. We evaluated potential changes in systemic hemodynamics and improved kidney function induced by the molecular adsorbent recirculating system (MARS) in a group of patients with primary nonfunction (PNF). PATIENTS AND METHODS: In the intensive care unit we treated 18 patients with PNF (6 females and 12 males) after orthotopic liver transplantation (OLT) of overall mean age 47.8 years (range, 28-60 years). Continuous MARS treatment was performed on all patients with a kit change every 8 hours during a mean of 10 days (range, 1-20 days). Double-lumen catheter type veno-venous access was used for the blood supply. The blood flow rate was 150 to 250 mL/min, depending on the hemodynamic situation of the patient. Blood passed through an albumin nonpermeable, high flux dialysis membrane. During MARS treatment we monitored the hemodynamic condition, using a series of parameters: heart rate (HR), mean arterial pressure (MAP), cardiac index (CI), systemic vascular resistance index (SVRI), and pulmonary vascular resistance index (PVRI) before (baseline value) as well as after 1 hour (T1), 3 hours (T2), and the end of treatment (T3). RESULTS: There was a progressive decrease in positive inotropic support (dobutamine, norepinephrine) and significant improvement in hemodynamic parameters, such as MAP (P< .01), PVRI/SVRI/V(mean) (P< .002), and KARI (P< .01). The improved kidney functions were shown by significant improvements in serum creatinine (P< .03), urea (P< .02), and urine volume (P< .005). Eleven patients were alive: 6 with OLT and 5 without OLT. Seven patients died: 4 after OLT and 3 before OLT due to multiorgan failure. CONCLUSIONS: The MARS device significantly improved the hemodynamic parameters and kidney function that also determine patient survival in ALF (61.1%) with PNF while awaiting retransplantation presumably by removal of certain vasoactive substances.

RESUMO

BACKGROUND: The molecular adsorbent recirculating system (MARS) is an extracorporeal acute liver failure (ALF) support system method using albumin-enriched dialysate to remove albumin-bound toxins. PATIENTS AND METHODS: Since 1999 we performed 2027 MARS treatments in 191 patients: 39 fulminant hepatic failure (FHF), 16 primary nonfunction (PNF), 21 delayed function (DF), 94 acute-on-chronic liver failure (AoCHF), 7 post-hepatic resection, and 14 intractable pruritus. RESULTS: We divided the complications by the AoCHF versus the ALF populations. Among 83 ALF patients, we observed worsening of hemodynamic parameters in 16 patients: 3 with PNF, 2 with DF without retransplantation, 9 with FHF, and 2 after hepatic resection. Among 94 AoCHF patients, 42 showed hemodynamic instability requiring intensive care unit support. Our study did not note significant adverse effects (1.8%), except for infections and hemorrhage from the central venous catheter not due to MARS treatment. The thrombocytopenia was controlled through administration of platelets before the start of treatment when a patient showed a level under 30,000 mm(3). CONCLUSION: Our results confirmed that nonbiological hepatic support by MARS was safe and tolerable.

RESUMO

In patients with end-stage chronic kidney disease (CKD) and type 1 diabetes mellitus (DM 1), simultaneous pancreas-kidney (SPK) transplantation is currently considered the gold standard therapy. The aim of this study was to analyze and report the long-term clinical outcomes of the 23 SPK transplantations performed at our institution over an 84-month period (January 1, 2000 to December 31, 2006). A prospective analysis of these patients included donor, recipient, and transplantation characteristics. The only requirements for transplantation were blood group compatibility and a negative cross-match. Bladder drainage via pancreaticoduodenocystostomy was performed in all of the patients. Due to a pulmonary embolus 1 patient (4.3%) died at 2 months. The actuarial patient survival rates at 3 months and 1, 3, and 5 years were 95.6%. Causes for the renal graft loss were chronic allograft nephropathy in 3 cases (13%) and death of the patient in 1 case (4.3%). The actuarial censored renal allograft survival rates at 3 months and at 1 year were 100%, and at 3 and 5 years were 91.3%. Causes for the renal graft loss were chronic rejection in 1 case (4.3%) and patient death in 1 case (4.3%). The actuarial censored pancreatic allograft survival rates at 3 months and at 1 and 3 years were 100%, and at 5 years was 95.6%. The results of this work add further evidence that SPK is the gold standard therapy for selected patients with end-stage CKD due to DM 1.

RESUMO

Polycystic disease causes a progressive decrease in renal function and liver degeneration. The progression of the disease evolves separately between organs and transplantation options vary: simultaneous or sequential liver-kidney transplantation or single-organ transplantation. From September 2006 to June 2007 3 combined liver kidney transplantations (CLKT) were performed for polycystic disease with end-stage renal disease: 2 with polycystic liver disease, and 1 with hepatic failure due to congenital hepatic fibrosis. The widest dimensions of the polycystic liver of 50 and 60 cm diameter were due to extensive cystic degeneration. We performed 1 simultaneous CLKT and 2 sequential transplantations: 1 liver after kidney, and 1 kidney after liver. At present all patients are alive with 100% graft function. Median creatinine level at discharge was 0.9 mg/dL (ranges, +/-0.2). Good liver graft function was reported in all 3 cases. Transplant benefit in polycystic liver-kidney disease has been already demonstrated; conservative surgical options may result in a high incidence of complications in highly involved polycystic livers. Delaying transplantation results in a more difficult surgical technique, a higher rate of postoperative complications, and a disturbance of optimal graft retrieval because of the worse preoperative condition of the patients.

RESUMO

INTRODUCTION: Two opposing views of the human body have existed since time began. Can it be traded or does its value go beyond a monetary one? Today it is illegal to sell organs but the success of organ transplantation has give rise to an enormous controversy. The continued increase in the need for organs has lead to a major use of live donors. Consequently, clandestine selling of organs is becoming more widespread for two main reasons: scientific progress and market demand. Our aim was to consider the protection of ethical principles through legislation. MATERIALS AND METHODS: Based on the principle that it is morally unacceptable for people to die on a waiting list, we analysed various ways in which the National Health Service could give incentives to live donors, including reimbursement of health expenses, tax relief, pension or early retirement benefits, or education grants for the children. Possible incentives for cadaveric organ donation included reimbursal of health and funeral costs, or increase in widow/er's pension. CONCLUSION: The tendency may be toward reimbursement of costs rather than actual payments. A legal, ethical organ market could save thousands of human lives, but it must be correctly regulated.

RESUMO

Fertility is usually restored in women after solid organ transplantation, and successful pregnancies have been reported in female recipients of kidney, liver, heart, pancreas-liver, and lung transplants. However, women with solid organ allografts have higher incidence of pregnancy complications like hypertension, preeclampsia, preterm delivery. Hypertension appears to be dependent on the type of immunosuppressive agents. The influence of pregnancy on the risk of rejection is poorly known on the basis of available data. Rejection rate appears to be at least similar to the nonpregnant population. In some cases, such as in liver transplant pregnant women, even higher as compared to the nonpregnant population. Maintaining appropriate blood levels of immunosuppressive drugs is currently recommended. Malformation rate in the offsprings of transplanted women appears to not be increased; long-term follow- up of children born to allograft recipients is necessary to investigate possible developmental, immunological, or oncological disorders. We followed 70 pregnancies after kidney transplantation and nine after liver transplantation. All recipients were maintained on immunosuppressive therapy during pregnancy, except one mother who refused immunosuppression and experienced transplant rejection. Hypertension was the most frequent complication during pregnancy: in 23% of kidney transplantated mothers and in one out of nine liver transplant recipients. The only malformation observed in the newborns was the dislocation of the hip in the child of a kidney transplant recipient.

RESUMO

UNLABELLED: Cerebral dysfunction may be fatal in patients with acute liver failure (ALF); intracranial pressure (ICP) monitoring may be mandatory to direct measures to prevent further cerebral edema. Recently the introduction of dialysis with the molecular adsorbent recirculating system (MARS) has improved the outcomes among patients with ALF. The aim of this study was to evaluate ICP changes after MARS treatment among patients with ALF. METHODS: Three patients -- 14, 18 and 16 years old -- were admitted to the ICU for acute liver failure induced by HBV in two cases and by acetaminophen in the other one. Because of Glasgow Coma Score (GCS) <8, they were intubated and ventilated to protect the airway and maintain moderate hypocapnia. Invasive monitoring of intracranial pressure MARS treatments were performed in all patients. RESULTS: The patients received MARS treatments every day after their admission to liver transplantation. After MARS therapy the ICP decreased on average from 21 to 7 mm Hg. Significant hemodynamic modifications were not observed and their neurological conditions improved. CONCLUSION: MARS treatment improved the clinical pictures of these patients increasing the available time to obtain an urgent liver graft.

RESUMO

Hepatocellular carcinoma (HCC) is considered an optimal indication for liver transplantation (LT) because it may eliminate both the tumor and the underlying liver disease. The present study sought to compare cumulative survival, rate of HCC recurrence, and causes of death among patients with cirrhosis and HCC before and after the adoption of more restrictive criteria (Milan selection criteria) at the time of patient listing. Among 226 adult patients who received an elective liver transplantation between 1999 and 2005, 58 (27%) had a diagnosis of HCC at the time. The 38 patients who underwent transplantation for HCC in the period 1989 to 1998 were considered the "historical group." After LT (mean follow-up, 34 + 28 months), the cumulative survival rate was better among HCC versus non-HCC recipients (93% vs 71% at 1 year and 81% vs 67% at 3 years, respectively; P < .046), although the difference tended to attenuate after 5 years (66% vs 67%, respectively). Tumor recurrence (evaluated in patients surviving at least 3 months after LT) was observed in 10/31 in the historical group versus 4/53 among those who underwent transplantation after 1999. Among the causes of death, recurrence represented 50% in the old series and 23% in patients who underwent transplantation after 1999. Cumulative survival significantly improved among HCC patients who underwent transplantation after 1999 (93% vs 66% at 1 year and 81% vs 50% at 3 years; P < .00001). The 58 patients who underwent transplantation with a diagnosis of cirrhosis and concomitant HCC after 1999 showed even better survival than patients who underwent transplantation for end-stage liver disease without malignancy.
