Stepwise options for preparing therapeutic plasma proteins from domestic plasma in low- and middle-income countries

Industrial plasma fractionation, a complex and highly regulated technology, remains largely inaccessible to many low- and middle-income countries (LMICs). This, combined with the limited availability and high cost of plasma-derived medicinal products (PDMPs), creates deficiency of access to adequate treatment for patients in resource-limited countries, and leads to their suffering. Meanwhile, an increasing number of LMICs produce surplus plasma, as a by-product of red blood cell preparation from whole blood, that is discarded because of the lack of suitability for fractionation. This article reviews pragmatic technological options for processing plasma collected from LMICs into therapies and supports a realistic stepwise approach aligned with recent World Health Organization guidance and initiatives launched by the Working Party for Global Blood Safety of the International Society of Blood Transfusion. When industrial options based on contract or toll plasma fractionation programme and, even more, domestic fractionation facilities require larger volumes of quality plasma than is produced, alternative methods should be considered. In-bag minipool or small-scale production procedures implementable in blood establishments or national service centres are the only realistic options available to gradually reduce plasma wastage, provide safer treatments for patients currently treated with non-pathogen-reduced blood products and concurrently improve Good Manufacturing Practice (GMP) levels with minimum capital investment. As a next step, when the available volume of quality-assured plasma reaches the necessary thresholds, LMICs could consider engaging with an established fractionator in a fractionation agreement or a contract in support of a domestic fractionation facility to improve the domestic PDMP supply and patients' treatment.

Delivery of AAV-based gene therapy through haemophilia centres-A need for re-evaluation of infrastructure and comprehensive care: A Joint publication of EAHAD and EHC

INTRODUCTION

Adeno-associated virus (AAV)-based gene therapy for haemophilia presents a challenge to the existing structure of haemophilia centres and requires a rethink of current collaboration and information exchange with the aim of ensuring a system that is fit-for-purpose for advanced therapies to maximise benefits and minimise risks. In Europe, a certification process based on the number of patients and facilities is offered to the haemophilia centres by European Haemophilia Network (EUHANET).

AIM AND METHODS

This joint European Association for Haemophilia and Allied Disorders (EAHAD) and European Haemophilia Consortium (EHC) publication describes criteria for centres participating in gene therapy care that require a reassessment of the infrastructure of comprehensive care and provides an outlook on how these criteria can be implemented in the future work of haemophilia centres.

RESULTS

The core definition of a haemophilia treatment centre remains, but additional roles could be implemented. A modifiable 'hub-and-spoke' model addresses all aspects associated with gene therapy, including preparation and administration of the gene therapy product, determination of coagulation and immunological parameters, joint score and function, and liver health. This will also include the strategy on how to follow-up patients for a long-term safety and efficacy surveillance.

CONCLUSION

We propose a modifiable, networked 'hub and spoke' model with a long term safety and efficacy surveillance system. This approach will be progressively developed with the goal of making haemophilia centres better qualified to deliver gene therapy and to make gene therapy accessible to all persons with haemophilia, irrespective of their country or centre of origin.

The Italian institutional accreditation model for Haemophilia Centres

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.

Haemophilia in the developing countries: the Iranian experience

INTRODUCTION

Management of haemophilia and inherited bleeding disorders is a major challenge especially in developing countries, because of a shortage or absence of products, the cost and the infrastructural health problems. Development of local expertise which results in an improved outlook and reduction in mortality and morbidity in these countries can be helpful for advocators in other developing countries. However, very little information on demography and organizational models for haemophilia care in developing countries are available in the literature. Our aim is a comprehensive report of haemophilia status and its management in Iran.

MATERIAL AND METHODS

THE MANAGEMENT CENTER OF TRANSPLANTATION AND SPECIAL DISEASES (MCTSD) OF THE MINISTRY OF HEALTH OF IRAN DECIDED TO CARRY OUT A COMPLETE REVIEW AND COMPILATION OF ALL OF THE PUBLISHED OR AVAILABLE DATA ABOUT PATIENTS WITH HAEMOPHILIA (PWH) IN IRAN: their health status, their management planning, organizations, treatment products, facilities and care problems during 2007.

RESULTS

6496 patients with congenital bleeding disorders were registered. Most of them had haemophilia A and B and von Willebrand disease (vWD). However, rare bleeding disorders are seen more than expected. Inhibitor development is 14-28%. There are different data about virological status of PWH. Factor products and facilities are fairly available with more than 1.5 units per capita of inhabitant factor consumption.

CONCLUSIONS

A national formulary based on facilities of the country should be considered and followed by collaboration among the Ministry Of Health, universities and non-governmental organizations.
