RESUMO

Autologous CD19-directed chimeric antigen receptor (CAR)-T cells have shown unprecedented efficacy in children with relapsed/refractory B-cell precursor acute lymphoblastic leukemia (BCP-ALL). However, patients either relapsing after allogeneic hematopoietic stem cell transplantation (allo-HSCT) or displaying profound lymphopenia and/or rapidly progressing disease often cannot access autologous products. These hurdles may be overcome by allogeneic, donor-derived CAR-T cells. We tested donor-derived T cells transduced with a second-generation (4.1BB) CD19-directed CAR for treatment of patients with BCP-ALL in a hospital-exemption setting. Two constructs were tested: a retroviral construct incorporating the suicide gene inducible caspase-9 (CD19-CAR-Retro_ALLO) first and then a lentiviral construct and an automated, Prodigy-based manufacturing process (CD19-CAR-Lenti_ALLO). Thirteen children/young adults received ALLO-CAR-T cells between March 2021 and October 2022. Doses ranged between 1.0 × 106 and 3.0 × 106 CAR-T cells per kg. The toxicity profile was comparable with that of autologous CAR-T cells, characterized mainly by cytopenia, cytokine release syndrome (maximum grade 1), and grade 2 immune-effector cell-associated neurotoxicity syndrome. One case of acute graft-versus-host disease (GVHD) occurred and was rapidly controlled with steroids and ruxolitinib. None of the other patients, including 3 given ALLO-CAR-T cells from an HLA-haploidentical donor, experienced GVHD. Two patients received ALLO-CAR-T cells before HSCT and showed a significant expansion of CAR-T cells without any sign of GVHD. All patients obtained complete remission (CR) with absence of minimal residual disease in the bone marrow. With a median follow-up of 12 months (range, 5-21), 8 of 13 patients maintained CR. Allogeneic anti-CD19 CAR-T cells can effectively treat highly refractory BCP-ALL relapsing after allo-HSCT without showing increased toxicity as compared with autologous CAR-T cells.

RESUMO

OBJECTIVE: The aim of this study is to report the safety and efficacy of CD19-targeting chimeric antigen receptor (CAR) T cells in a child with refractory juvenile dermatomyositis (JDM). METHODS: We describe a 12-year-old White male with severe, chronically active JDM refractory to multiple immunosuppressive treatment lines, including B cell depletion with rituximab. The patient received a single infusion of fresh, autologous, second-generation anti-CD19 CAR T cell product (lentiviral vector) manufactured on the Prodigy device (1 × 106 CAR T cells/kg), after lymphodepletion with cyclophosphamide (1,000 mg/m2 over two days) and fludarabine (90 mg/m2 over three days). Immunosuppressive and glucocorticoid treatment were withdrawn before leukapheresis and CAR T cell infusion. RESULTS: Before anti-CD19 CAR T cell therapy, the patient had persistent severe skin and muscular disease activity. CAR T cells expanded significantly (peak at day 7, 32.69 cells/µL). Complete B cell depletion was documented on day 5 in the blood and at week 2 in the bone marrow. The patient presented with fever as part of mild cytokine release syndrome (grade 1), transient anemia (grade 2), and neutropenia (grade 4). Neither infection nor neurotoxicity were observed. Laboratory tests, magnetic resonance imaging, Physician Global Assessment of disease activity, Childhood Myositis Assessment Scale, and Cutaneous Assessment Tool for myositis were performed at baseline and follow-up to assess treatment response, showing remarkable progressive improvement that persists over time, even after B cell recovery. CONCLUSION: This patient with JDM with severe chronic disease, refractory to multiple treatments, achieved sustained B cell depletion and ongoing immunosuppressive drug-free clinical and radiologic improvement eight months after a single infusion of anti-CD19 CAR T cells.

RESUMO

The seventh multi-stakeholder Paediatric Strategy Forum focused on chimeric antigen receptor (CAR) T-cells for children and adolescents with cancer. The development of CAR T-cells for patients with haematological malignancies, especially B-cell precursor acute lymphoblastic leukaemia (BCP-ALL), has been spectacular. However, currently, there are scientific, clinical and logistical challenges for use of CAR T-cells in BCP-ALL and other paediatric malignancies, particularly in acute myeloid leukaemia (AML), lymphomas and solid tumours. The aims of the Forum were to summarise the current landscape of CAR T-cell therapy development in paediatrics, too identify current challenges and future directions, with consideration of other immune effector modalities and ascertain the best strategies to accelerate their development and availability to children. Although the effect is of limited duration in about half of the patients, anti-CD19 CAR T-cells produce high response rates in relapsed/refractory BCP-ALL and this has highlighted previously unknown mechanisms of relapse. CAR T-cell treatment as first- or second-line therapy could also potentially benefit patients whose disease has high-risk features associated with relapse and failure of conventional therapies. Identifying patients with very early and early relapse in whom CAR T-cell therapy may replace haematopoietic stem cell transplantation and be definitive therapy versus those in whom it provides a more effective bridge to haematopoietic stem cell transplantation is a very high priority. Development of approaches to improve persistence, either by improving T cell fitness or using more humanised/fully humanised products and co-targeting of multiple antigens to prevent antigen escape, could potentially further optimise therapy. Many differences exist between paediatric B-cell non-Hodgkin lymphomas (B-NHL) and BCP-ALL. In view of the very small patient numbers with relapsed lymphoma, careful prioritisation is needed to evaluate CAR T-cells in children with Burkitt lymphoma, primary mediastinal B cell lymphoma and other NHL subtypes. Combination trials of alternative targets to CD19 (CD20 or CD22) should also be explored as a priority to improve efficacy in this population. Development of CD30 CAR T-cell immunotherapy strategies in patients with relapsed/refractory Hodgkin lymphoma will likely be most efficiently accomplished by joint paediatric and adult trials. CAR T-cell approaches are early in development for AML and T-ALL, given the unique challenges of successful immunotherapy actualisation in these diseases. At this time, CD33 and CD123 appear to be the most universal targets in AML and CD7 in T-ALL. The results of ongoing or planned first-in-human studies are required to facilitate further understanding. There are promising early results in solid tumours, particularly with GD2 targeting cell therapies in neuroblastoma and central nervous system gliomas that represent significant unmet clinical needs. Further understanding of biology is critical to success. The comparative benefits of autologous versus allogeneic CAR T-cells, T-cells engineered with T cell receptors T-cells engineered with T cell receptor fusion constructs, CAR Natural Killer (NK)-cell products, bispecific T-cell engager antibodies and antibody-drug conjugates require evaluation in paediatric malignancies. Early and proactive academia and multi-company engagement are mandatory to advance cellular immunotherapies in paediatric oncology. Regulatory advice should be sought very early in the design and preparation of clinical trials of innovative medicines, for which regulatory approval may ultimately be sought. Aligning strategic, scientific, regulatory, health technology and funding requirements from the inception of a clinical trial is especially important as these are very expensive therapies. The model for drug development for cell therapy in paediatric oncology could also involve a 'later stage handoff' to industry after early development in academic hands. Finally, and very importantly, strategies must evolve to ensure appropriate ease of access for children who need and could potentially benefit from these therapies.

RESUMO

INTRODUCTION: This paper reports 17 years of passive safety surveillance of routine use of the pediatric hexavalent diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliovirus-Haemophilus influenzae type b-conjugate vaccine (DTPa-HBV-IPV/Hib, Infanrix hexa, GSK). METHODS: Global post-licensure passive surveillance data collected in GSK's central safety database since DTPa-HBV-IPV/Hib's launch (2000) are described. RESULTS: The most common spontaneously reported adverse events (AEs) after DTPa-HBV-IPV/Hib vaccination in children were fever (reporting rate: 7.74/100,000 doses distributed), crying (2.62/100,000), injection site erythema (1.87/100,000) and swelling (1.28/100,000). A review of extensive limb swelling did not reveal any safety concerns. An observed-to-expected analysis did not show an increased risk of sudden death after DTPa-HBV-IPV/Hib vaccination, in line with previous observations. The analyses confirmed that increases in spontaneous reporting proportions of convulsions with/without fever and hypotonic-hyporesponsive episodes after co-administration of DTPa-HBV-IPV/Hib and 13-valent pneumococcal conjugate vaccine remained small and their clinical significance unknown. The most common vaccination errors were mistakes in the vaccination schedule. Reporting of preparation errors (mostly reconstitution) was low and did not impact the vaccine's benefit-risk profile. CONCLUSIONS: Seventeen years of post-licensure experience confirm confidence in the safety profile of DTPa-HBV-IPV/Hib in routine use, with a favorable benefit-risk profile in infants and toddlers. PLAIN LANGUAGE SUMMARY: What is the context? The cornerstone of childhood vaccination in many countries worldwide is a vaccine that protects against several diseases: diphtheria, tetanus, whooping cough, hepatitis B, polio and Haemophilus influenzae type b infections (such as meningitis). One of these vaccines (the longest on the market) is called Infanrix hexa; it has been available for infants and toddlers since 2000. After a vaccine is included in a country's routine vaccination program, its safety is constantly checked; this is done in clinical trials and through spontaneous reporting of adverse events after vaccination. It is important to share up-to-date information on the safety of vaccines, particularly since concerns about vaccine safety in parents may lead to lower vaccination rates an disease outbreaks. Here we summarize 17 years of safety data for the Infanrix hexa vaccine. What is new? We analyzed spontaneously reported adverse events after Infanrix hexa vaccinations between 2000 and 2017 The most commonly reported adverse events were fever, crying and injection site redness and swelling An in-depth review of extensive limb swelling after Infanrix hexa vaccination revealed no safety concerns. There was no increased risk of sudden death after Infanrix hexa vaccination, consistent with what was shown in several other studies. As shown previously, seizures were more common when Infanrix hexa was given together with the pneumococcal conjugate vaccine, Prevnar 13, than when it was given alone. What is the take-home message? The large amount of safety data gathered from clinical trials and from spontaneous adverse event reporting during 17 years of routine vaccination with Infanrix hexa supports its continued use in young children.

RESUMO

UNLABELLED: The presence of the metabolic syndrome (MetS) is an important risk factor for cardiovascular disease and diabetes. There are limited data on the prevalence of MetS in patients with schizophrenia at the onset of the disorder and specifically no data on patients treated in the era when only first-generation antipsychotics were available. METHODS: Data from a historic cohort of consecutively admitted first-episode patients with schizophrenia treated with first-generation antipsychotics (FGAs) were compared with an age and sex matched series of consecutive first-episode patients treated only with second-generation antipsychotics (SGAs). Rates of MetS were compared at baseline and after on average 3 years of treatment exposure. RESULTS: At first episode there was no difference in the prevalence of MetS between the historic and the current cohort. Rates of MetS increased over time in both groups, but patients started on SGAs had a three times higher incidence rate of MetS (Odds Ratio 3.6, CI 1.7-7.5). The average increase in weight and body mass index was twice as high in patients started on SGA. The difference between the FGA and SGA group was no longer significant when patients started on clozapine and olanzapine were excluded. CONCLUSION: Rates of MetS at the first episode of schizophrenia today are not different from those of patients 15 to 20 years ago. This finding counters the notion that the high rates of metabolic abnormalities in patients with schizophrenia currently reported are mainly due to lifestyle changes over time in the general population. Some SGAs have a significantly more negative impact on the incidence of MetS compared to FGAs in first-episode patients.

RESUMO

BACKGROUND: In recent years, several studies showed increased rates of hyperglycaemia, diabetes, dyslipidemia, metabolic syndrome as well as cardiovascular disease in schizophrenic patients. The underlying mechanism, however, is poorly understood. Adiponectin is a recently identified adipocyte-derived protein, with low adiponectin levels being associated with metabolic abnormalities such as obesity, insulin resistance and type 2 diabetes. METHODS: Fasting adiponectin levels were assessed in a cross-sectional sample of 386 patients with schizophrenia or schizoaffective disorder. All patients were on monotherapy of second-generation antipsychotics (SGA) and underwent an extensive metabolic screening including an oral glucose tolerance test (OGTT). RESULTS: Adiponectin plasma levels were inversely correlated with BMI, and differed significantly between patients with normal weight, overweight or obesity (p<0.05). Patients who met criteria for the metabolic syndrome, according to adapted National Cholesterol Educational Program - Adult Treatment Panel criteria (NCEP-ATP III) (29.3%), had significantly lower adiponectin levels than patients not meeting metabolic syndrome criteria (p<0.0001). Patients without glucose abnormalities (78%) had significantly higher adiponectin levels than patients with diabetes (5.7%) (p<0.05). After controlling for components of metabolic syndrome and sex, antipsychotic medication independently influenced adiponectin levels (p<0.0001), with the lowest mean levels in patients on clozapine and olanzapine. CONCLUSIONS: Adiponectin levels in schizophrenic patients mirror what is observed in the general population, with the lowest levels in the most metabolically comprised subjects. However, antipsychotic medication may also influence adiponectin regulation independently, a finding that should be confirmed in longitudinal studies.

RESUMO

BACKGROUND: The aim of this paper is to evaluate the effect of antipsychotics for the treatment of schizophrenia in a community based study on sexual function and prolactin levels comparing the use of aripiprazole and standard of care (SOC), which was a limited choice of three widely used and available antipsychotics (olanzapine, quetiapine or risperidone) (The Schizophrenia Trial of Aripiprazole [STAR] study [NCT00237913]). METHOD: This open-label, 26-week, multi-centre, randomised study compared aripiprazole to SOC (olanzapine, quetiapine or risperidone) in patients with schizophrenia (DSM-IV-TR criteria). The primary effectiveness variable was the mean total score of the Investigator Assessment Questionnaire (IAQ) at Week 26. The outcome research variables included the Arizona Sexual Experience scale (ASEX). This along with the data collected on serum prolactin levels at week 4, 8, 12, 18 and 26 will be the focus of this paper. RESULTS: A total of 555 patients were randomised to receive aripiprazole (n = 284) or SOC (n = 271). Both treatment groups experienced improvements in sexual function from baseline ASEX assessments. However at 8 weeks the aripiprazole treatment group reported significantly greater improvement compared with the SOC group (p = 0.007; OC). Although baseline mean serum prolactin levels were similar in the two treatment groups (43.4 mg/dL in the aripiprazole group and 42.3 mg/dL in the SOC group, p = NS) at Week 26 OC, mean decreases in serum prolactin were 34.2 mg/dL in the aripiprazole group, compared with 13.3 mg/dL in the SOC group (p < 0.001). CONCLUSION: The study findings suggest that aripiprazole has the potential to reduce sexual dysfunction, which in turn might improve patient compliance.

RESUMO

OBJECTIVE: To evaluate quality of life and patient preference for schizophrenia treatment in a community based study comparing the use of aripiprazole to the standard of care (SOC). METHOD: This open-label, 26-week, multi-centre, randomised study compared aripiprazole with SOC (olanzapine, quetiapine or risperidone) in patients with schizophrenia (DSM-IV-TR criteria). The primary effectiveness variable was the mean total score of the Investigator Assessment Questionnaire (IAQ) at Week 26. The outcome research variables included the Preference of Medicine (POM) questionnaire, the Quality of Life Scale (QLS), and the EuroQoL-5D (EQ-5D). The results from these outcome research variables are the focus of this paper addressing quality of life and patient preference. RESULTS: A total of 555 patients were randomised to receive aripiprazole (n=284) or SOC (n=271). The OC data at Week 26, reported that more respondents rated the study medication as 'much better' compared with their previous medication in the aripiprazole group versus SOC for patients (59% vs 35%, P<0.001) and caregivers (58% vs 30%, P=0.014). The improvement in QLS total score was also significantly greater in the aripiprazole group compared with SOC--mean change from baseline in QLS total score of 16.21 vs 10.01 (P<0.001) at Week 26 (OC data set). A greater proportion of patients (93% vs 85%; P=0.005) in the aripiprazole group had a satisfactory response on the EQ-5D Self Care Scale; all other EQ-5D scores were similar. CONCLUSION: The study findings suggest that quality of life and patient medication preference measures were better for aripiprazole than for SOC.

RESUMO

INTRODUCTION: Combination vaccines improve vaccine uptake and open the infant immunization space for additional vaccines. Hexavalent vaccines have been marketed since 2000. Infanrix hexa (combined diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliovirus-Haemophilus influenzae type b conjugate vaccine, DTPa-HBV-IPV/Hib, GSK) is longest on the market, providing 16 years post-marketing experience. Each DTPa-HBV-IPV/Hib vaccine component is licensed alone and/or in smaller combination vaccines. Programmatic considerations sometimes require an interchange between vaccines due to unavailability, program change or mixed schedules (when the number of required antigens differs across scheduled primary vaccination visits). AREAS COVERED: Immunogenicity and safety data from 11 GSK-sponsored clinical trials support the interchangeability of DTPa-HBV-IPV/Hib within the same vaccines family, and use of DTPa-HBV-IPV/Hib in mixed primary vaccination schedules. EXPERT COMMENTARY: Data show acceptability of interchange of DTPa-HBV-IPV/Hib with other products within the same vaccines family and its use in mixed immunization schedules. This aligns with WHO recommendations that vaccines of the same family from the same manufacturer be used to complete the infant vaccination schedule. Interchangeability and suitability for use in mixed schedules is of interest for policy-makers/providers in the framework of vaccination recommendations as it provides flexibility. Given the complexity of larger combination vaccines, interchangeability or sequential use needs careful assessment.

RESUMO

Pregnancy and the postpartum period are associated with elevated risks to both mother and infant from infectious disease. Vaccination of pregnant women, also called maternal immunization, has the potential to protect pregnant women, foetuses and infants from several vaccine-preventable diseases. Maternal immunoglobulin G antibodies are actively transferred through the placenta to provide passive immunity to new-borns during the first months of life, until the time for infant vaccinations or until the period of greatest susceptibility has passed. Currently, inactivated influenza, tetanus, and pertussis vaccines are recommended during pregnancy in many countries, but other vaccines may also be administered to pregnant women when risk factors are present. Several new vaccines with a specific indication for use during pregnancy are under development (e.g. respiratory syncytial virus and group B streptococcus vaccines). Years of experience suggest that maternal immunization against influenza, tetanus or pertussis has an acceptable safety profile, is well tolerated, effective and confers significant benefits to pregnant women and their infants. This review describes the principles of maternal immunization and provides an update of the recent evidence regarding the use and timing of maternal immunization. Finally, the barriers preventing wider vaccination coverage and the current limitations in addressing these are also described ( Supplementary Material ). Key messages Maternal immunization gives pregnant women greater protection against infectious diseases; induces high levels of maternal antibodies that can be transferred to the foetus; and helps protect new-borns during their first months of life, until they are old enough to be vaccinated. Pregnant women and new-borns are more vulnerable to infectious diseases than the overall population; nevertheless, vaccination rates are often low in pregnant women. This review provides an update of the recent evidence regarding the use and timing of maternal immunization and describes the barriers preventing wider vaccination uptake and the current limitations in addressing these.

RESUMO

BACKGROUND: Infants with history of prematurity (<37 weeks gestation) and low birth weight (LBW, <2500 g) are at high risk of infection due to functional immaturity of normal physical and immunological defense mechanisms. Despite current recommendations that infants with history of prematurity/LBW should receive routine immunization according to the same schedule and chronological age as full-term infants, immunization is often delayed. METHODS: Here we summarize 10 clinical studies and 15 years of post-marketing safety surveillance of GSK's hexavalent vaccine (DTPa-HBV-IPV/Hib), a combined diphtheria-tetanus-acellular-pertussis-hepatitis-B-inactivated-poliovirus-Haemophilus influenzae-type-b (Hib) conjugate vaccine, when administered alone, or co-administered with pneumococcal conjugate, rotavirus, and meningococcal vaccines and respiratory syncytial virus IgG to infants with history of prematurity/LBW in clinical trials. RESULTS: At least 92.5% of infants with history of prematurity/LBW as young as 24 weeks gestation in clinical studies were seropositive to all vaccine antigens after 3-dose primary vaccination with GSK's hexavalent DTPa-HBV-IPV/Hib vaccine, with robust immune responses to booster vaccination. Seropositivity rates and antibody concentrations to hepatitis B and Hib appeared lower in infants with history of prematurity/LBW than term infants. Between 13-30% of medically stable infants with history of prematurity developed apnea after vaccination with GSK's hexavalent DTPa-HBV-IPV/Hib vaccine; usually after dose 1. The occurrence of post-immunization cardiorespiratory events appears to be influenced by the severity of any underlying neonatal condition. Most cardiorespiratory events resolve spontaneously or require minimal intervention. GSK's hexavalent DTPa-HBV-IPV/Hib vaccine was well tolerated in co-administration regimens. CONCLUSION: GSK's hexavalent DTPa-HBV-IPV/Hib vaccine alone or co-administered with other pediatric vaccines has a clinically acceptable safety and immunogenicity profile when used in infants with history of prematurity/LBW for primary and booster vaccination. Additional studies are needed in very premature and very LBW infants. However, currently available data support using GSK's hexavalent DTPa-HBV-IPV/Hib vaccine to immunize infants with history of prematurity/LBW according to chronological age.

RESUMO

Metabolic abnormalities occur frequently in patients treated with antipsychotics and are of growing concern to clinicians. This study sought to determine whether antipsychotic-associated metabolic abnormalities identified through intensive monitoring can be reversed by switching to aripiprazole. Recent evidence suggests that aripiprazole may exhibit a favorable metabolic safety profile. The study population is a subset of a large (n > 500) ongoing prospective cohort. Thirty-one consecutive patients with schizophrenia who were started on aripiprazole were included in the study. All patients underwent an extensive metabolic evaluation, including an oral glucose tolerance test, at baseline, at 6 weeks, and at 3 months post switch. Metabolic abnormalities were defined as any of the following: new onset diabetes, impaired fasting glucose, impaired glucose tolerance, metabolic syndrome (MetS) according to various definitions, and dyslipidemia. After 3 months of treatment with aripiprazole (mean daily dose 16.3 mg), there was a significant decrease in body weight, body mass index, and waist circumference. There was a significant reduction in fasting glucose, fasting insulin, insulin resistance index, and serum lipids levels (cholesterol, triglycerides, low-density lipoprotein (LDL), LDL/HDL, Chol/HDL, and non-HDL cholesterol). There was also a significant reduction in prolactin levels. All 7 cases of recent onset diabetes were reversed at 3 months follow-up. The MetS was reversed in 50% of patients at 3 months follow-up. Our results support the reversibility of recent onset diabetes on antipsychotic medication when detected early and followed by a switch to aripiprazole.

RESUMO

Mortality rates in patients with schizophrenia are double compared with the general population, with cardiovascular disease causing 50% of the excess. Lowering low-density lipoprotein cholesterol is recognized as a primary target for the prevention of cardiovascular mortality. The effects of lipid-lowering treatment were evaluated in patients with schizophrenia. Forty-six patients with schizophrenia and with severe dyslipidaemia were identified. All were treated with antipsychotics. Patients were screened for cardiovascular risk factors and examined at baseline when statin therapy was initiated. The effects of lipid-lowering medication on lipid profile, glucose homeostasis and components of metabolic syndrome were evaluated at 3 months follow-up. After 3 months of statin therapy, a significant decrease in triglycerides, total cholesterol, low-density lipoprotein cholesterol, non-high-density lipoprotein cholesterol, and, in associated ratios, low-density lipoprotein/high-density lipoprotein, cholesterol/high-density lipoprotein was observed. No significant changes occurred in high-density lipoprotein cholesterol, body mass index, waist circumference or glucose homeostasis. The only component of metabolic syndrome affected by statin therapy has been the serum triglyceride level. Statins proved effective in the management of dyslipidaemia in patients with schizophrenia treated with antipsychotics. More complex treatment may be required for associated metabolic disturbances.

RESUMO

BACKGROUND: Naturalistic effectiveness trials of atypical antipsychotics are needed to provide broader information on efficacy, safety, and tolerability in patients with schizophrenia treated in a community practice setting. METHOD: In this 26-week, open-label, multicentre study, patients with schizophrenia requiring a switch in antipsychotic medication because current medication was not well tolerated and/or clinical symptoms were not well controlled were randomized to receive aripiprazole or an atypical antipsychotic standard of care (SOC) treatment (i.e., olanzapine, quetiapine, or risperidone based on the investigator's judgment of the optimal treatment for the individual patient and the patient's prior response to antipsychotic medication). The primary objective was to compare the effectiveness of a 26-week treatment of aripiprazole versus SOC, as measured by the Investigator Assessment Questionnaire (IAQ) total score at Week 26 last observation carried forward (LOCF) (primary endpoint), a validated measure that monitors relief or worsening of 10 key symptoms associated with the psychopathology of schizophrenia and side effects of antipsychotic treatment. Secondary objectives were to further assess effectiveness using the Clinical Global Impression - Global Improvement (CGI-I) and Clinical Global Impression - Severity of Illness scale, to assess time to treatment discontinuation, patient preference of medication, quality of life, and the tolerability of aripiprazole compared with SOC. RESULTS: Aripiprazole treatment (n=268) resulted in significantly better effectiveness than SOC treatment (n=254; P<0.001; Week 26 LOCF) as evidenced by the IAQ total score beginning at Week 4 (the first assessment point) and sustained through Week 26. A similar relationship was demonstrated among patients who completed the study (observed cases analysis); aripiprazole was associated with significantly better effectiveness at all time points with a greater differential effect from SOC over time. Patients treated with aripiprazole also demonstrated significantly greater improvements on the CGI-I scale (responder rate, P=0.009 at Week 26 LOCF), as well as on quality of life (Quality of Life scale total score; P<0.001 at Week 26). Furthermore, a significantly higher proportion of patients receiving aripiprazole rated their study medication as "much better" on the Preference of Medication Questionnaire (POM) scale than their pre-study medication compared with SOC patients (P<0.001; Week 26). Time to treatment discontinuation and rates of discontinuation due to adverse events were similar in both treatment groups. The incidence of patients with one or more extrapyramidal symptom (e.g., akathisia, dystonia, parkinsonian events, and residual events) was higher in patients receiving aripiprazole compared with patients treated with SOC (13.5% vs. 5.6%); however, a higher proportion of patients in the SOC-treated group had clinically significant weight gain (21.2% vs. 7.3% for aripiprazole) and potentially clinically relevant elevated fasting levels of total cholesterol, low-density lipoprotein cholesterol, triglycerides, and serum prolactin compared with patients receiving aripiprazole. CONCLUSIONS: Aripiprazole is an effective atypical antipsychotic for the treatment of schizophrenia, demonstrating better effectiveness than SOC agents used in this study in patients for whom a switch in antipsychotic medication was warranted.

RESUMO

INTRODUCTION: The development of diphtheria-tetanus-acellular pertussis-Haemophilus influenzae type b (Hib) conjugate vaccine combinations culminated with hexavalent vaccines, the largest, most complex vaccine combinations in the immunization calendar. Hexavalent vaccines are used widely in Europe and are co-administered with multiple other recommended vaccines. Hib immunogenicity may reduce when combined with acellular pertussis antigens, or in some co-administrations. We reviewed the epidemiology of H. influenzae disease in Europe aiming to evaluate the current level of Hib control and indirectly assess the effectiveness against Hib of GSK's hexavalent vaccine in 10 countries where it is/has been used almost exclusively. Areas covered: We reviewed surveillance data from the European Union Invasive Bacterial Infections Surveillance Network and the European Surveillance System database from 1999-2014 and extracted case and incidence/notification rates (per 100,000 population) of invasive H. influenzae disease. We included age and serotype/strains distribution among countries in the European Union/European Economic Area region that reported to the European Centre for Disease Prevention and Control surveillance system. Expert commentary: The impact of Hib vaccination in Europe is sustained, testifying to continued effectiveness against invasive Hib disease after the implementation of hexavalent vaccines into immunization programs, which, since 2006, has been almost exclusively GSK´s hexavalent DTPa-HBV-IPV/Hib vaccine.

RESUMO

UNLABELLED: The presence of the metabolic syndrome is an important risk factor for cardiovascular disease and diabetes. There are limited data on the prevalence of the metabolic syndrome in European patients suffering from schizophrenia. METHODS: All consecutive patients with schizophrenia at our university psychiatric hospital and affiliate services were entered in an extensive prospective metabolic study including an oral glucose tolerance test. The prevalence of the metabolic syndrome was assessed based on the National Cholesterol Education Program criteria (NCEP, Adult Treatment Protocol, ATP-III), adapted ATP-III criteria using a fasting glucose threshold of 100 mg/dl (AHA) and on the recently proposed criteria from the International Diabetes Federation (IDF). RESULTS: The analysis of 430 patients showed a prevalence of the metabolic syndrome of 28.4% (ATP-III), 32.3% (ATP-III A) and 36% (IDF), respectively. The prevalence of the metabolic syndrome in our sample of patients with schizophrenia is at least twice as high compared to an age-adjusted community sample in Belgium. CONCLUSION: The metabolic syndrome is highly prevalent among treated patients with schizophrenia. It represents an important risk for cardiovascular and metabolic disorders. Assessment of the presence and monitoring of the associated risks of the metabolic syndrome should be part of the clinical management of patients treated with antipsychotics.

RESUMO

BACKGROUND: Metabolic abnormalities and weight gain are an important problem in patients with schizophrenia. An instrument to evaluate body image and self-esteem related to weight has recently been developed (B-WISE). The first objective was to evaluate whether the findings of the original validation study could be confirmed in a European sample. The second objective was to explore the association of B-WISE scores with the metabolic syndrome and glucose abnormalities. METHODS: A Dutch translation of B-WISE was tested in a large sample of patients with schizophrenia (n=300) who underwent an extensive metabolic screening. RESULTS: The original findings with B-WISE were confirmed in an independent sample. Scores on B-WISE differed significantly as a function of BMI. Scores on B-WISE also differentiated patients with and without the metabolic syndrome and glucose abnormalities. Patients experiencing a recent weight gain had lower self-esteem and poorer psychosocial adaptation. CONCLUSION: B-WISE could be a useful instrument to evaluate the subjective psychosocial consequences associated with current weight and weight gain in patients with schizophrenia.

RESUMO

OBJECTIVE: A recent consensus conference has proposed guidelines for the monitoring for diabetes in patients with schizophrenia and also identifies the need of long-term prospective studies. METHOD: A large scale prospective study on metabolic risks of antipsychotic medication is currently ongoing. At baseline, patients get a full laboratory screening, ECG and an oral glucose tolerance test (OGTT). Baseline data on 100 non-diabetic patients at study inclusion and stable on medication for at least 6 months are presented. RESULTS: Glucose abnormalities are found in 22% of patients at baseline. A monitoring protocol based only on fasting glucose would not have detected 63.6% of these patients with classifiable glucose abnormalities in our sample. Fasting insulin and measures for insulin resistance have a high predictive value for abnormalities late in the OGTT. CONCLUSION: Already at baseline, metabolic problems are frequently present in patients with schizophrenia treated with antipsychotics. Adding assessment of fasting insulin in a monitoring protocol improves detection of glucose abnormalities late in an OGTT.

RESUMO

BACKGROUND: Vaccinating infants against hepatitis B virus (HBV) is the most effective way of preventing the disease. However, since HBV exposure can increase during adolescence, it is essential that antibody persistence is maintained. We evaluated the antibody persistence and immune memory against hepatitis B, in 12-13 y olds who had received complete primary + booster vaccination with diphtheria-tetanus-acellular pertussis-hepatitis B-inactivated poliovirus/Haemophilus influenza type b (DTPa-HBV-IPV/Hib) vaccine in infancy. METHODS: Open phase-IV study conducted at 12 centers in Germany [NCT02052661]. Adolescents aged 12-13 y, vaccinated with 4 doses of DTPa-HBV-IPV/Hib (Infanrix hexa™, GSK Vaccines) in infancy, received a single challenge dose of monovalent pediatric hepatitis B vaccine (Engerix™-B Kinder; GSK Vaccines). Blood samples were taken before and 1-month post-challenge to measure anti-hepatitis B (anti-HBs) antibodies using a chemiluminescence immunoassay (seroprotection cut-off: ≥10 mIU/ml). Post-challenge adverse events (AEs) were monitored. RESULTS: 300 subjects were vaccinated; of 293 subjects in the ATP immunogenicity cohort, 60.5% had pre-challenge anti-HBs antibodies ≥10 mIU/ml, which rose to 97.6% post-challenge (≥100 mIU/ml in 94.1%). An anamnestic response was seen in 96.5% subjects. A 150-fold increase in antibody geometric mean concentrations was observed (22.4 to 3502.6 mIU/ml). Pain (44%) and fatigue (24.3%) were the most frequent solicited local and general AEs, respectively; 14.7% subjects reported unsolicited symptoms during the 31-day post-vaccination period. Two vaccine-unrelated serious AEs occurred. CONCLUSION: Vaccination with DTPa-HBV-IPV/Hib in infancy induces sustained seroprotection and immune memory against HBV, as shown by the strong anamnestic response to the hepatitis B vaccine challenge in 12-13 year-old adolescents.
