Reversal of heart failure in thalassemia major by combined chelation therapy: a case report.

In patients with thalassemia major (TM) who are non-compliant with long-term desferrioxamine (DFO) chelation, survival is limited mainly because of cardiac complications of transfusional hemosiderosis. Combined chelation therapy with DFO and deferiprone has maximized the efficacy of the therapy and reduced cardiological complications. The aim of this report is to present the results of this combination in a desperate case of heart failure.

Transfusional hemosiderosis and combined chelation therapy in sickle thalassemia.

Although the indications for transfusions in sickle cell syndromes are well listed, and chronic transfusion has become practicable since the recent advances in chelation therapy have essentially eliminated the risk of secondary iron overload, multi-transfused, non-compliant to long-term chelation therapy patients confront the complication of iron overload and secondary hemosiderosis. In thalassemia major patients, combined therapy with desferrioxamine and deferiprone has maximized tissue iron removal and may reduce the overall occurrence of hemosiderotic heart failure. Despite this, safety and contradictions of chelating agents are still controversial. The aim of this report is to present the results of this combination in a long-term transfused sickle beta-thalassemic patient suffering from severe heart failure and liver dysfunction.

A macro-directive mechanism that facilitates automatic updating and processing of the contents of Electronic Healthcare Records: an extension to the CEN architecture.

Facilitating data entry, eliminating redundant effort and providing decision support are some of the factors upon which the successful uptake of Electronic Healthcare Record (EHCR) technology is dependent. The European Standardization Committee (CEN), on the other hand, has proposed a standard EHCR architecture, which allows patient record contents to be highly diverse, customized to individual user needs; this makes their processing a challenging task and poses a demand for specially designed mechanisms. We describe the requirements for a macro-directive mechanism, pertaining to CEN-compatible EHCR software that can automate updating and processing of patient records, thus enhancing the functionality of the software. We have implemented the above-mentioned mechanism in an EHCR application that has been customized for use in the care process of patients suffering from beta-Thalassemia. The application is being used during the last two years in the Thalassemia units of four Greek hospitals, as part of their every day practice. We report on the experience we have acquired so far.

A Java-based electronic healthcare record software for beta-thalassaemia.

BACKGROUND: Beta-thalassaemia is a hereditary disease, the prevalence of which is high in persons of Mediterranean, African, and Southeast Asian ancestry. In Greece it constitutes an important public health problem. Beta-thalassaemia necessitates continuous and complicated health care procedures such as daily chelation; biweekly transfusions; and periodic cardiology, endocrinology, and hepatology evaluations. Typically, different care items are offered in different, often-distant, health care units, which leads to increased patient mobility. This is especially true in rural areas. Medical records of patients suffering from beta-thalassaemia are inevitably complex and grow in size very fast. They are currently paper-based, scattered over all units involved in the care process. This hinders communication of information between health care professionals and makes processing of the medical records difficult, thus impeding medical research. OBJECTIVES: Our objective is to provide an electronic means for recording, communicating, and processing all data produced in the context of the care process of patients suffering from beta-thalassaemia. METHODS: We have developed - and we present in this paper - Java-based Electronic Healthcare Record (EHCR) software, called JAnaemia. JAnaemia is a general-purpose EHCR application, which can be customized for use in all medical specialties. Customization for beta-thalassaemia has been performed in collaboration with 4 Greek hospitals. To be capable of coping with patient record diversity, JAnaemia has been based on the EHCR architecture proposed in the ENV 13606:1999 standard, published by the CEN/TC251 committee. Compliance with the CEN architecture also ensures that several additional requirements are fulfilled in relation to clinical comprehensiveness; to record sharing and communication; and to ethical, medico-legal, and computational issues. Special care has been taken to provide a user-friendly, form-based interface for data entry and processing. RESULTS: The experience gained through the use of JAnaemia in 4 Greek hospitals reveals a significant contribution towards (1) improvement of the quality of the data being recorded, since data entry is guided by appropriate forms, (2) easier cooperation between physicians, who share a common information repository, and (3) increased processing capabilities, which facilitate medical research. CONCLUSIONS: JAnaemia appears to be a useful tool, which can improve the quality of care offered to beta-thalassaemic patients in Greece.
