RESUMO

This review is focused on the use of hyperimmune globulin therapy to treat some infectious diseases of viral or bacterial origin. Despite the introduction of antibiotics and vaccines, plasma immunoglobulin therapy from whole blood donation can still play a key role. These treatments provide passive transfer of high-titer antibodies that either reduces the risk or the severity of the infection and offer immediate but short-term protection against specific diseases. Antibody preparations derived from immunized human donors are commonly used for the prophylaxis and treatment of rabies, hepatitis A and B viruses, varicella-zoster virus, and pneumonia caused by respiratory syncytial virus, Clostridium tetani, Clostridium botulinum. The use of hyperimmune globulin therapy is a promising challenge, especially for the treatment of emerging viral infections for which there are no specific therapies or licensed vaccines.

RESUMO

Since the inception of industrial plasma fractionation during the Second World War, a succession of protein therapies isolated from plasma have determined the volume of plasma requiring collection, and have also shaped the economics of the industry. These so-called plasma drivers have successively included albumin, coagulation Factor VIII (FVIII) and, for the past thirty years, intravenously (IV) and subcutaneously (SC) administered immunoglobulin (IG) solutions. The sale of IG underpins the profitability of the industry and has experienced continuous growth over the past decades, as the result of growing clinical demand. Modelling this demand using decision analysis indicates that supplying the evidence-based indications for IG therapies will generate a need for IG which exceeds the current plasma collection capacity of most countries. A notable exception to this situation is the United States (US) of America, whose population of compensated plasma donors generates two thirds of the global supply of plasma for fractionation. The US is also the leading consumer of IG, and its health care providers pay the highest price for the product globally. Shortages of IG occur whenever the demand for the product outstrips the supply. Current shortages, following other historical periods of shortage, threaten the well-being of patients dependant on these products and incur heavy costs on health systems. In Italy, the national blood system, which is based on voluntary unpaid donors, reflects a policy of national self-sufficiency in blood-derived therapies (a strategic objective of the national blood system itself), based on solidarity as an ethical principle. This system has increased the collection of plasma for fractionation by 3.8% per annum over 2008-2017, in accordance to a plan for plasma procurement targeting a collection rate of 14.1 L of plasma per thousand (103) population by 2020. Over the same period, IG usage has increased by 8.5/per annum, to 89.2 g IG/103 population. In this paper, we review the factors which, increasingly, are causing an imbalance between the global supply and demand for IG, and we assess Italy's capacity to ensure that increasing this level of independence is no longer simply an ethical, but also an economic imperative, with implications for the security of Italy's health system.

RESUMO

BACKGROUND: Platelet-rich plasma (PRP) has been used in different non-transfusion indications due to its role in tissue regeneration and healing. The aim of this overview of systematic reviews (umbrella review) is to provide a summary of the existing research syntheses related to PRP use for sports-related muscle, tendon and ligament injuries. MATERIALS AND METHODS: Literature searches were performed in MEDLINE, Embase, and Cochrane Library to identify systematic reviews focusing on PRP use for sports-related muscle, tendon and ligament injuries. The methodological quality of included studies was assessed using the checklist for systematic reviews and research syntheses developed by the Joanna Briggs Institute and the GRADE assessment. RESULTS: Twenty-two studies met the inclusion criteria. Five studies evaluated PRP use for acute muscle injury, and 17 evaluated PRP use for tendon and ligament injury. Studies were heterogeneous in terms of the dose and number of PRP injections, and the control groups. Three of the 5 reviews evaluating acute muscle injury concluded that PRP had no effect on the outcomes considered. One review shows superior efficacy of rehabilitation exercise compared to PRP. One review shows that PRP may result in an earlier return to sport for acute grade I-II injury. Eight out of the 17 reviews evaluating PRP for tendon and ligament injuries show a statistically significant (p<0.05) difference in pain and/or function outcome measures favouring PRP compared to controls, although most of the observed differences were small. Adverse events data and quality of life outcomes were rarely analysed or reported in the included studies and were considered clinically insignificant. DISCUSSION: In most of the included reviews, the available evidence was judged to be of low/very low quality due to risk of bias, inconsistency and imprecision, thus making the level of certainty of these findings low and not adequate to support the general use of PRP in this setting.

RESUMO

Patient Blood Management (PBM) is a multimodal, multidisciplinary approach adopted to limit the use and the need for allogeneic blood transfusion in all at-risk patients with the aim of improving their clinical outcomes. Although PBM usually refers to surgical patients, its clinical use has gradually evolved over the last few years and it now also refers to medical conditions. This review will critically analyse the current knowledge on the use of PBM programmes in surgical and non-surgical patients.

RESUMO

One of the most serious complications of the treatment of severe haemophilia A is the development of alloantibodies against exogenous factor VIII (FVIII). Inhibitors render factor replacement therapy ineffective, exposing patients to a remarkably high risk of morbidity and mortality. Besides the well-known bypassing agents (i.e. activated prothrombin complex concentrate and recombinant activated factor VII) used to treat or prevent bleeding in haemophilia patients with inhibitors, there is growing interest in newer haemostatic therapies that are not based on the replacement of the deficient FVIII. This review will focus on the most interesting among these innovative therapies, emicizumab, and will provide an update on its current stage of clinical development.

RESUMO

Selecting therapeutic products for the treatment of haemophilia follows the process of obtaining market approval of products submitted to the scrutiny of a regulatory agency. In well-resourced countries, key decisions on whether a product is sufficiently safe and of high quality are made by highly expert and well-resourced agencies, such as the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA). In countries lacking such agencies, well-informed decisions can still be made through an appreciation of the key issues affecting the quality, safety and efficacy of haemophilia products. A number of well-established principles may then be applied in order to make a choice. In this review, reflecting principles outlined by the World Federation of Hemophilia, we outline the key features in determining the acceptability of therapeutic products for haemophilia in order to ensure an optimal choice in all the environments providing haemophilia care.

RESUMO

BACKGROUND: In Italy, basic health needs of patients with inherited bleeding disorders are met by a network of 50 haemophilia centres belonging to the Italian Association of Haemophilia Centres. Further emerging needs, due to the increased life expectancy of this patient group, require a multi-professional clinical management of the disease and provide a challenge to the organisation of centres.In order to achieve harmonised quality standards of haemophilia care across Italian Regions, an institutional accreditation model for haemophilia centres has been developed. MATERIAL AND METHODS: To develop an accreditation scheme for haemophilia centres, a panel of experts representing medical and patient bodies, the Ministry of Health and Regional Health Authorities has been appointed by the National Blood Centre. Following a public consultation, a technical proposal in the form of recommendations for Regional Health Authorities has been formally submitted to the Ministry of Health and has formed the basis for a proposal of Agreement between the Government and the Regions. RESULTS: The institutional accreditation model for Haemophilia Centres was approved as an Agreement between the Government and the Regions in March 2013. It identified 23 organisational requirements for haemophilia centres covering different areas and activities. DISCUSSION: The Italian institutional accreditation model aims to achieve harmonised quality standards across Regions and to implement continuous improvement efforts, certified by regional inspection systems. The identified requirements are considered as necessary and appropriate in order to provide haemophilia services as "basic healthcare levels" under the umbrella of the National Health Service. This model provides Regions with a flexible institutional accreditation scheme that can be potentially extended to other rare diseases.

RESUMO

INTRODUCTION: Due to the increase in life expectancy, patients with haemophilia and other inherited bleeding disorders are experiencing age-related comorbidities that present new challenges. In order to meet current and emerging needs, a model for healthcare pathways was developed through a project funded by the Italian Ministry of Health. The project aimed to prevent or reduce the social-health burden of the disease and its complications. MATERIAL AND METHODS: The National Blood Centre appointed a panel of experts comprising clinicians, patients, National and Regional Health Authority representatives. Following an analysis of the scientific and regulatory references, the panel drafted a technical proposal containing recommendations for Regional Health Authorities, which has been formally submitted to the Ministry of Health. Finally, a set of indicators to monitor haemophilia care provision has been defined. RESULTS: In the technical document, the panel of experts proposed the adoption of health policy recommendations summarised in areas, such as: multidisciplinary integrated approach for optimal healthcare provision; networking and protocols for emergency care; home therapy; registries/databases; replacement therapy supply and distribution; recruitment and training of experts in bleeding disorders. The recommendations became the content of proposal of agreement between the Government and the Regions. Monitoring and evaluation of haemophilia care through the set of established indicators was partially performed due to limited available data. CONCLUSIONS: The project provided recommendations for the clinical and organisational management of patient with haemophilia. A particular concern was given to those areas that play a critical role in the comorbidities and complications prevention. Recommendations are expected to harmonise healthcare care delivery across regional networks and building the foundation for the national haemophilia network.
