Giorgia Gollo,1 Gaia Savioli,2 Manuela Balocco,2 Cristina Venturino,3 Elio Boeri,4 Massimo Costantini,1 Gian Luca Forni21Regional Palliative Care Network, IRCCS AOU San Martino-IST, Genoa; 2Hematology, Center for Thalassemia, Galliera Hospital, Genoa, 3Psychiatric Service, Galliera Hospital, Genoa, 4Department of Hematology and Oncology, Gaslini Institute, Genoa, Italy Background: The prolonged survival of patients with thalassemia major as a result of the novel therapeutic strategies introduced in the last decade makes patient quality of life an important issue. This study investigated the changes occurring in overall quality of life in patients with thalassemia in the last decade.Methods: This was a population-based cross-sectional survey of quality of life in the entire population with thalassemia major resident in the Liguria region of Italy from 2001 to 2009. The self-administered Short Form-36 (SF-36) questionnaire was used to measure quality of life in patients with thalassemia.Results: Forty-nine and 52 eligible patients were assessed in 2001 and 2009, respectively. A total of 43 patients were assessed in both 2001 and 2009. Almost 40% of these 43 patients received deferasirox in 2009, a drug which was not available in 2001. The distribution of ferritin levels was lower in 2009 (median 730) as compared with 2001 (median 1107). Analysis of the raw differences between the two years did not show a significant difference. An improvement was observed in most SF-36 scales in 2009 as compared with 2001, particularly in the Mental Health scale (mean difference in Z score +4.0; 95% confidence interval 0.4–7.5; P = 0.030) and in the Mental Component Summary scale (mean difference in Z score +3.2; 95% confidence interval 0.2–6.2; P = 0.039).Conclusion: The challenge associated with new therapies and improvement in mental quality of life dimensions indicates that implementation of effective interventions for screening and evaluation of quality of life is now urgent.Keywords: thalassemia major, quality of life, survey, Short Form-36

Abstract

Aim: This study aimed to investigate the role of resistance-associated substitutions (RASs) to direct-acting-antivirals (DAAs) in HCV genotype 3 (GT3). Methods: Within the Italian VIRONET-C network, a total of 539 GT3-infected patients (417 DAA-naïve and 135 DAA-failures, of them, 13 at both baseline and failure) were analysed. Sanger sequencing of NS3/NS5A/NS5B was performed following home-made protocols. Results: The majority of patients were male (79.4%), 91.4% were injection drug users, 49.3% were cirrhotic and 13.9% were HIV co-infected. Phylogenetic analysis classified sequences as GT3a-b-g-h (98%-0.4%-0.2%-1.2%) respectively. Overall, 135 patients failed a DAA regimen: sofosbuvir (SOF)/daclatasvir (DCV) or velpatasvir (VEL)±ribavirin (RBV) (N=91/15) and glecaprevir (G)/pibrentasvir (P) (N=9). Moreover, 14.8% of patients were treated with suboptimal regimens for GT3: 3D±RBV (Paritaprevir/r+Ombitasvir+Dasabuvir, N=15), SOF+Simeprevir (SIM) (N=1) or SOF/Ledipasvir (LDV)±RBV (N=4). RAS prevalence was 15.8% in DAA-naïve patients. At failure, 81.5% patients showed at least one RAS: 11/25 (44.0%) in NS3, 109/135 (80.7%) in NS5A, 7/111 (6.3%) in NS5B SOF-failures. In NS5A-failures, Y93H RAS was the most prevalent (68.5% vs 5.1% DAA-naïve, P&nbsp

Abstract

HIV-1 drug resistance represents a major obstacle to infection and disease control. This retrospective study analyzes trends and determinants of resistance in antiretroviral treatment (ART)-exposed individuals across 7 countries in Europe. Of 20 323 cases, 80% carried at least one resistance mutation: these declined from 81% in 1997 to 71% in 2008. Predicted extensive 3-class resistance was rare (3.2% considering the cumulative genotype) and peaked at 4.5% in 2005, decreasing thereafter. The proportion of cases exhausting available drug options dropped from 32% in 2000 to 1% in 2008. Reduced risk of resistance over calendar years was confirmed by multivariable analysis. © 2013 The Author.

Abstract

Objectives: To test retrospectively the ability of four freely available rules-based expert systems to predict short- and medium-term virological outcome following an antiretroviral treatment switch in pre-treated HIV-1 patients. Methods: The HIV-1 genotype interpretation systems (GISs) HIVdb, ANRS, Rega and AntiRetroScan were tested for their accuracy in predicting response to highly active antiretroviral therapy using 8 week (n = 765) and 24 week (n = 634) follow-up standardized treatment change episodes extracted from the Italian Antiretroviral Resistance Cohort Analysis (ARCA) database. A genotypic sensitivity score (GSS) was derived for each genotype-treatment pair for the different GISs and tested as a predictor of virological treatment outcome by univariable and multivariable logistic regression as well as by receiver operating characteristic curve analysis. The two systems implementing drug potency weights (AntiRetroScan and Rega) were evaluated with and without this correction factor. Results: All four GSSs were strong predictors of virological treatment outcome at both 8 and 24 weeks after adjusting for baseline viro-immunological parameters and previous drug exposure (odds ratios ranging from 2.04 to 2.43 per 1 unit GSS increase; P < 0.001 for all the systems). The accuracy of AntiRetroScan and Rega was significantly increased by drug potency weighting with respect to the unweighted versions (P ≤ 0.001). HIVdb and ANRS also increased their performance with the same drug potency weighting adopted by AntiRetroScan and Rega, respectively (P < 0.001 for both analyses). Conclusions: Currently available GISs are valuable tools for assisting antiretroviral treatment choices. Drug potency weighting can increase the accuracy of all systems. © The Author 2009.

Abstract

Many persons with severe haemophilia reach seniority thanks to effective treatment. There is no information on health-related quality of life (HRQoL) of these patients, who had lived for many years when regular replacement therapy was unavailable. Italian patients with severe haemophilia aged ≥65 years born in the 1940s or earlier were compared with men without bleeding disorders matched for age and geography. HRQoL was assessed via generic and disease-specific questionnaires. Potential associations with concomitant illnesses, orthopaedic status, physical functioning, cognitive status and depression were evaluated. In addition, the newly adapted HRQoL questionnaire specific for elderly persons with haemophilia (Haem-A-QoL(Eldlery)) was psychometrically tested and validated. Thirty-nine patients, aged 65-78 years, were investigated, 33 with haemophilia A and six with haemophilia B, and compared to 43 controls, aged 65-79 years. Chronic blood borne viral infections, hypertension and arthropathy were more frequent in patients, whereas hypercholesterolemia and cardiovascular diseases were more frequent in controls. Psychometric characteristics of Haem-A-QoL(Elderly) showed good to excellent values for reliability and validity. HRQoL was worse in patients at EQ-VAS, WHOQOL-BREF and WHOQOL-Old. The highest impairments were found in patients by means of the haemophilia-specific Haem-A-QoL(Elderly) in such dimensions as 'physical activityleisure', 'physical health' and 'view'. A poor orthopaedic status was negatively associated with HRQoL. Compared to age-matched controls elderly patients with haemophilia had an impaired HRQoL in association with their health status. The newly developed Haem-A-QoL(Elderly) proved to be a reliable and valid instrument for HRQoL assessment in elderly haemophilia patients.

Abstract

Introduction: This study aimed at defining protease (PR) resistance mutations associated with darunavir (DRV) failure and PR resistance evolution at DRV failure in a large database of treatment-experienced human immunodeficiency virus (HIV) patients. Results: Overall, 1,104 patients were included: 118 (10.7%) failed at a median observation time of 16 months. The mean number of PR mutations at baseline was 2.7, but it was higher in patients who subsequently failed DRV. In addition, the number of PR mutations increased at failure. The increase in the mean number of mutations was completely related to mutations considered to be associated with DRV resistance following the indications of the main DRV clinical trials. Discussion The higher statistical difference at baseline between failing versus non-failing patients was observed for the V32I and I84V mutations. At DRV failure, the major increase was still observed for V32I; I54L, V11I, T74P and I50V also increased. Despite the increment in the mean number of mutations per patient between baseline and failure, in 21 patients (17.8%) at baseline and 36 (30.5%) at failure, no PR mutation was detected. Conclusion: The HIV-DB interpretation algorithm identified few patients with full DRV resistance at baseline and few patients developed full resistance at DRV failure, indicating that complete resistance to DRV is uncommon. © Springer-Verlag 2011.

Abstract

An investigation was undertaken to determine whether specific pol mutations hinder long-term immune recovery regardless of virological response. In total, 826 patients with >50 HIV RNA copies/ml, who underwent genotypic resistance testing between 1 January 2000 and 31 December 2003 after >3 years of antiretroviral treatment, and were followed up for >3 years after genotypic resistance testing, were analyzed retrospectively. The outcome of the study was the lack of immune recovery after >3 years of follow-up, defined as a slope by linear regression 50 copies/ml divided by the number of HIV RNA measurements during follow-up. Logistic regression was used for univariable and multivariable analysis. Median (Q1, Q3) values at baseline were the following: age 40 (37, 45) years, years on antiretroviral therapy 4.45 (3.65, 5.47), HIV RNA 3.91 (3.39, 4.53) log 10 copies/ml, CD4+ T-cell 358 (211, 524)/μl. After 3.13 years of follow-up, 375 patients (45.4%) showed a lack of immune recovery. The risk of lack of immune recovery increased independently with increasing baseline CD4+ counts (OR=1.104 per 50-cell increase, 95% CI=1.069-1.142, P

Abstract

Although a number of studies have analysed so far the causes of death and the life expectancy in haemophilic populations, no investigations have been conducted among Italian haemophilia centres. Thus, the aim of this study was to investigate mortality, causes of deaths, life expectancy and co-morbidities in Italian persons with haemophilia (PWH). Data pertaining to a total of 443 PWH who died between 1980 and 2007 were retrospectively collected in the 30 centres who are members of the Italian Association of Haemophilia Centres that chose to participate. The mortality rate ratio standardized to the male Italian population (SMR) was reduced during the periods 1990-1999 and 2000-2007 such that during the latter, death rate overlapped that of the general population (SMR 1990-1999: 1.98 95% CI 1.54-2.51; SMR 2000-2007: 1.08 95% CI 0.83-1.40). Similarly, life expectancy in the whole haemophilic population increased in the same period (71.2 years in 2000-2007 vs. 64.0 in 1990-1999), approaching that of the general male population. While human immunodeficiency virus infection was the main cause of death (45%), 13% of deaths were caused by hepatitis C-associated complications. The results of this retrospective study show that in Italian PWH improvements in the quality of treatment and global medical care provided by specialized haemophilia centres resulted in a significantly increased life expectancy.

Abstract

SUMMARY BACKGROUND: More and more people with severe hemophilia reach an old age thanks to an effective treatment. There is no information on the health status and quality of life of elderly people with hemophilia born at a time when replacement therapy was hardly available. METHODS: Italian patients with severe hemophilia, aged >or=65 years and hence born in 1942 or earlier, were compared with elderly men without bleeding disorders matched for age, sex, geography and social status. The following aspects were evaluated: concomitant illness, orthopedic status, physical functioning and cognitive status. Measurements of generic and disease-specific health-related quality of life were also obtained, together with the presence or absence of depression. RESULTS: Thirty-nine patients, aged 65-78 years, were investigated; 33 had hemophilia A. All patients had started regular treatment on demand only when they were already 25-30 years of age. Patients were compared with 43 men without hemophilia, aged 65-79 years. More patients with hemophilia had chronic hepatitis B and C, HIV infection and hypertension. On the other hand, their elderly peers without hemophilia were more frequently hypercholesterolemic and had more cardiovascular diseases. Most hemophiliacs had arthropathy and worse values for physical functioning, but their cognitive status was similar to that of elderly non-hemophiliacs. Hemophiliacs reported greater depression and lower health-related quality of life. CONCLUSIONS: Elderly patients with hemophilia have more co-morbidities and problems in daily living, but similar cognitive status as age-matched non-hemophilic peers. They have more chronic viral infections and hypertension but fewer cardiovascular diseases. These observations should help to optimize health care delivery in this increasing and neglected population of people with hemophilia.

Abstract

Data from the Italian Hemophilia Centres were collected to perform a retrospective survey of joint arthroplasty in patients with severe hemophilia. Twenty-nine of 49 hemophilia centers reported that 328 of the 347 operations were carried out in 253 patients with severe hemophilia A (HA) and 19 in 15 patients with severe hemophilia B (HB). When results were normalized to the whole Italian hemophilia population (1770 severe HA and 319 severe HB), patients with HA had a 3-fold higher risk of undergoing joint arthroplasty (odds ratio [OR], 3.38; 95% confidence interval [CI], 1.97-5.77; P < .001). These results were confirmed after adjustment for age, HIV, hepatitis C virus (HCV), and inhibitor in a Cox regression model (HR, 2.65; 95% CI, 1.62-4.33; P < .001). The survival analysis of time to joint arthroplasty in the subset of patients with severe HA was not affected by the severity of factor VIII (FVIII) gene mutations. A systematic review of literature articles reporting joint arthroplasties in HA and HB showed that the proportion of HA patients who had undergone arthroplasties was higher than that of HB patients, in agreement with the findings in our Italian cohort. These data suggest that the 2 inherited coagulation disorders have a different severity of clinical phenotype.

Abstract

von Willebrand disease (VWD) is the most common hereditary bleeding disorder affecting both males and females. It arises from quantitative or qualitative defects of von Willebrand factor (VWF) and causes bleeding of mucous membranes and soft tissues. The aim of treatment is to correct the dual defect of haemostasis caused by the abnormal/reduced VWF and the concomitant deficiency of factor VIII (FVIII).This document contains evidence-based recommendations for the management of VWD compiled by AICE (the Italian Association of Haemophilia Centres). All the evidence supporting these recommendations are based on non-randomised comparative studies or case series, because randomised controlled clinical trials or meta-analyses are not available for this disease.Desmopressin (DDAVP) is the treatment of choice for patients with type 1 VWD with FVIII and VWF levels of 10 U/dL or more, while VWF/FVIII concentrates are indicated for those who are unresponsive or insufficiently responsive to DDAVP (severe type 1, type 2 and 3 VWD). VWF concentrates devoid of FVIII, not yet licensed in Italy, may be considered for short-term prophylaxis in elective surgery or for long-term secondary prophylaxis.

Abstract

National haemophilia registries are powerful instruments to support health care and research. A national registry was established in Italy by the Ministry of Health until 1999. Since 2003 the Italian Association of Haemophilia Centres (AICE) started a new programme aiming at building up the Italian Registry of Haemophilia and Allied Disorders. The AICE identified an expert panel to steer the registry. A computer software to assist patient management was developed and all the AICE-affiliated haemophilia treatment centres (HTC) were prompted to adopt it. Twice a year a predefined set of anonymized data is centralized and merged into a national database. Duplicated entries are managed through a confidentiality sparing mechanism. The database covers sociodemographic, clinical, laboratory and treatment data. A subset of data are shared with the Ministry of Health (Istituto Superiore di Sanita,ISS).Overall, data were collected six times by 43 of 49 HTC; 41 centres updated their patients' records up to December 2006. The database contains 6632 unique records, 442 of them referring to dead patients. Database growth and missing data clearance showed a constantly positive trend over time. The database has collected records of the following alive patients - haemophilia A: 1364 severe, 398 moderate and 935 mild; haemophilia B: 231 severe, 138 moderate and 204 mild; von Willebrand's disease: 1208 type 1, 346 type 2 and 96 type 3. Inhibitor patients were 296 (of which 194 high responders and 65 low responders).The Italian registry run by AICE adds to the list of the available national haemophilia registries and is intended to establish treatment guidelines and foster research projects in Italy.

Abstract

BACKGROUND: Some technical aspects of laparoscopic spleen surgery still are debated, although efforts have been made to standardize them. The position of the patient, the approach to the spleen, vessel identification and division, and spleen extraction can vary from center to center. METHODS: This retrospective muticentric study led by the Società Italiana di Videochirurgia Infantile (SIVI) examined indications, surgical details, and complications of laparoscopic spleen surgery in the pediatric population during a 5-year period. RESULTS: The study period from January 1999 to December 2003 (5 years) involved nine centers and included 85 patients with a mean age of 10 years (range, 2-17 years). Hypersplenism or severe hemolysis in cases of hematologic disorders represented the most important indications. More than 90% of the patients underwent total laparoscopic splenectomy. Specific technical details from each center were collected. Intraoperative complications occurred in 19% of the patients (hemorrhage in 8% and technical problems in 14%), and 6% of the patients required conversion to the open approach. No deaths occurred, and no reoperations were required. Postoperative complications were experienced by 2% of the patients. CONCLUSION: Laparoscopic spleen surgery is safe, reliable, and effective in the pediatric population. On the basis of the results, some technical details for laparoscopic spleen surgery can be suggested. The patient is preferably kept supine or lateral, approaching the spleen anteriorly. Moreover, the ilar vessels should be identified selectively and individually, with initial artery division performed to achieve spleen shrinking. Any hemostatic device proved to be effective in experienced hands. Once freed, the spleen is preferably extracted via a suprapubic cosmetic transverse incision (faster, easier, and safer), although a bag can be used. Finally, the size of the spleen does not represent a contraindication for a trained and experienced surgeon. Nevertheless, this parameter must be considered when laparoscopic spleen surgery is planned.

Abstract

Due to the preferential selection of the fittest HIV mutants, drug-resistant variants are often overgrown by wild-type virus after treatment interruption. Our objective was to investigate the dynamics of the 103N mutation (which usually does not reduce HIV fitness) following the withdrawal of non-nucleoside reverse transcriptase inhibitors (NNRTIs). Patients who were found to have the 103N mutation at or after failure of a NNRTI were selected from an observational database. Two groups of patients were identified: one which continued antiretroviral treatment without NNRTIs (group A) and one which discontinued all anti-retrovirals after failure of an NNRTI (group B). Genotype was obtained by direct sequencing of the replicating plasma virus. Sixty-two subjects tested between July 1998 and December 2002 were included in the analysis, 39 in group A and 23 in group B. At the time of the first resistance test, median (IQR) CD4+ T-lymphocytes and HIV-RNA were 269 (150-449) cells/microL and 25,000 (9,600-83,300) copies/mL. In 31 (50%), 30 (48%), and one case (2%), the 103N mutation was selected by nevirapine, efavirenz, and by delavirdine, respectively. A total of 149 tests were analyzed, with a median (IQR) of 2 (2-3) tests/patient. The median (IQR) interval between failure of NNRTIs and the last resistance test was 11 (5-22) months. Overall, a reversion to wild-type at position 103 was observed in 23/62 (37%) subjects, 14/39 (36%) in group A and 9/23 (39%) in group B. In group A, 14/23 (61%) patients tested within 12 months, 10/16 (63%) of those tested between 12 and 24 months, and 12/14 (86%) of those tested beyond 24 months from NNRTI discontinuation had the 103N mutation. In group B, 14/20 (70%) patients tested within 12 months, 3/4 (75%) of those tested between 12 and 24 months, and none out of two tested beyond 24 months from NNRTI discontinuation had the 103N mutation. In conclusion, following NNRTI discontinuation, in the majority of patients HIV variants carrying the 103N mutation are not overgrown for long by wild-type quasispecies at this position. This suggests that the 103N mutation per se influences minimally the viral fitness in vivo.

Abstract

Genotypes in nine highly protease inhibitor (PI)experienced patients were studied before and after lopinavir/ritonavir (LPV/r) treatment. Resistance to amprenavir was the rule both before and after LPV/r treatment. Treatment with LPV/r can select for the 50V mutation. In this setting, significant differences in the inference of the amprenavir phenotype from genotype were observed when using different algorithms.

Abstract

Background. GB virus C, a positive-stranded RNA virus, is classified in the family Flaviviridae. It is currently believed that persistent infection occurs in 25-50% of infected individuals, however, it still remains an "orphan" virus in search of a role in human pathology. Molecular epidemiological studies have demonstrated that GBV-C infection is present in about 1-1.4% of the healthy population in developed countries, that it shares routes of transmission with HIV and HCV and that the prevalence of GBV-C in these populations is higher than in blood donors. On the basis of the sequence variation among the isolates, GBV-C is classified into at least four major genotypes. Preliminary evidence has suggested that GBV-C is a lymphotropic virus that replicates mainly in the spleen and bone marrow. Recently, several reports have investigated the possible beneficial effect of GBV-C co-infection on HIV disease progression to AIDS, reduced mortality in HIV infected individuals and lower HIV viral loads, not leading to a definitive conclusion yet. Aim. To investigate the role of GBV virus C co-infection in two different subsets of HIV-infected patients, and to evaluate the prevalence of GBV-C genotypes in Northern Italy. Methods. A total of 86 HIV positive patients were examined for GBV-C viremia (years after HIV sera conversion: 12 +/- 5). Control population (Group A): 46 patients (mean age 42 years) with 500 CD4/ml for at least 8 years and never treated with HAART. After extraction of viral RNA from plasma samples, amplification of a highly conserved region of 5'UTR was performed by nested RT-PCR. All positive samples were genotyped by sequencing, alignment with published sequences and phylogenetic analysis. CD4 cell count, HIV plasma levels were also evaluated. Results. 9 out of 46 (19.56%) in Group A and 15 out of 40 (37.5%) in Group B had detectable GBV-C viremia (p=0.064, OR 2.47, percent confidence interval 0.94 to 6.51). No statistical difference was observed when disease stage was evaluated between the two groups. In Group B, after regression analysis for CD4 cell count decrease over the period observed, no significant difference was detected between GBV-C positive and negative patients. No significant difference was observed in Group B in HIV viremia and CD4 cell count at time of GBV-C detection between GBV-C infected patients and GBV-C negative patients. All Italian patients were genotype 2, the only African patient carried GBV-C genotype 1. Conclusions. Although previous results suggest that GBV-C virus may be a favorable marker for long term non progression of HIV disease, whether it plays a direct anti-HIV role or just takes advantage of non progessors' higher CD4 cell count to replicate more efficiently, still remains to be answered. Follow up of untreated patients and further evaluation of virological interactions, between the viruses and the host immune system, will be helpful to shed some light on these observations, offering new prognostic and eventually therapeutical tools for the management of HIV patients.
