Worldwide Network for Blood and Marrow Transplantation Recommendations for Establishing a Hematopoietic Stem Cell Transplantation Program in Countries with Limited Resources, Part II: Clinical, Technical, and Socioeconomic Considerations.

The development of hematopoietic stem cell transplantation (HSCT) programs can face significant challenges in most developing countries because such endeavors must compete with other government health care priorities, including the delivery of basic services. Although this is may be a limiting factor, these countries should prioritize development of the needed expertise to offer state-of-the-art treatments, including transplantation, by providing financial, technological, legal, ethical, and other needed support. This would prove beneficial in providing successful programs customized to the needs of their population and potentially provide long-term cost savings by circumventing the need for their citizens to seek care abroad. The costs of establishing an HSCT program and the costs of the HSCT procedure itself can be substantial barriers in developing countries. In addition, socioeconomic factors intrinsic to specific countries can influence access to HSCT, patient eligibility for HSCT, and timely utilization of HSCT center capabilities. This report describes recommendations from the Worldwide Network for Blood and Marrow Transplantation for establishing HSCT programs, with a specific focus on developing countries, and identifies challenges and opportunities for providing this specialized procedure in resource-constrained settings.

Cost and quality issues in establishing hematopoietic cell transplant program in developing countries.

The hematopoietic cell transplant (HCT) activity has grown significantly over the past two decades in both developing and developed countries. Many challenges arise in establishing new HCT programs in developing countries, due to scarcity of resources and manpower in expertise in HCT. While cost issues can potentially hinder establishment of new HCT programs in certain regions, the focus on quality and value should be included in the general vision of leadership before establishing an HCT program. The main challenge in most developing countries is the lack of trained/qualified personnel, enormous start-up costs for a tertiary care center, and quality maintenance. Herein, we discuss the main challenges from a cost and quality perspective which occur at initiation of a new HCT program. We give real world examples of two developing countries that have recently started new HCT programs despite significant financial constraints. We also portray recommendations from the Worldwide Network of Blood and Marrow Transplantation for levels of requirements for a new HCT program. We hope that this review will serve as a general guide for new transplant program leadership with respect to the concerns of balancing high quality with concurrently lowering costs.

Correlation of hepatitis C RNA and serum alanine aminotransferase in hepatitis B and C seronegative healthy blood donors.

INTRODUCTION: Historically, serum alanine transaminase (ALT) has been used as a surrogate marker in the detection of hepatitis viruses in blood donors. With the availability of newer sensitive technologies for the detection of seroconversion, the value of ALT becomes questionable but continues to be used for this purpose with subsequent discarding of ALT elevated blood units. OBJECTIVE: The present study aims to evaluate the significance and cost effectiveness of ALT as a surrogate marker for hepatitis C virus infection in healthy asymptomatic blood donors who were serologically negative. MATERIALS AND METHODS: The study was conducted at clinical laboratory of a tertiary care hospital for a period of one year from November 2006 to October 2007. All donors were screened serologically for hepatitis B, C and HIV I and II, syphilis and malaria and those tested positive were excluded from further evaluation. Gender-wise reference ranges and minimal and markedly raised results for ALT (described respectively as one and two folds increase above reference range) were defined and, accordingly, donors were grouped into three. Two hundred seronegative blood donors were randomly selected from all three groups of ALT results and tested for hepatitis C nucleic acid through Amplicor HCV RNA test. The cost of discarding an ALT -only elevated blood unit was also assessed. During the study period, 25117 subjects donated blood. EIGHT HUNDRED AND RESULTS: Seventy two donors (3.4%) were positive for one or more serological tests. ALT of all donors ranged from 0-1501 U/L (Mean +/- SD; 33.4 +/- 25.45 U/L). The donors seronegative for all disease markers were 24245 (96.6%). Of these, 21164 (87.2%) donors had their ALT within reference range while 2874 (11.8%) and 207 (0.8%) of donors had minimal and markedly elevated results. Thus, 621 blood bags (red cells, platelets and plasma) costing $ 39200.0 were discarded based on ALT results alone. Of 200 seronegative donors evaluated for hepatitis C nucleic acid, only one within markedly elevated ALT levels was found to be positive. The present work did not support a positive association between hepatitis C virus nucleic acid and elevated ALT in healthy serologically negative blood donors. CONCLUSION: We did not find serum ALT testing in donors as cost effective strategy for detection of hepatitis C virus ribonucleic acid. As the number of samples tested by us was small we suggest further work to evaluate the value of ALT levels in serologically negative donors in association with hepatitis C antigen and NAT testing to elucidate the true burden of disease in geographical regions where hepatitis C is endemic and voluntary blood donation is sparse.

Status of hematopoietic stem cell transplantation in the WHO Eastern Mediterranean Region (EMRO).

Several centers are now performing allogeneic hematopoietic stem cell transplantation (HSCT) in the World Health Organization Eastern Mediterranean Region (EMRO) but the availability is still limited due to high cost and the need for multi-disciplinary team and an advanced laboratory support. Special issues including compatible donor availability, potential for alternate donor programs, differences in pattern of disease, pre-HSCT general status particularly for patients with BM failure, high sero-positivity for CMV, Hepatitis B and C infection and specific observations about GVHD with its relation to genetically homogeneous community are discussed. A total of 17 HSCT programs (performing five or more HSCTs annually) exist in nine countries of the EM region. Only six programs are currently reporting to EBMT or IBMTR. A total of 7617 HSCTs including 5701 allogeneic HSCTs have been performed. Due to low HSCT team density (1.5583 teams/10 million inhabitants versus 14.4333 in Europe) and very low HSCT team distribution (0.2729 teams/10,000 sq km area versus <1 to 6 teams in Europe) only 70.8% of total population has access to such a program in EM region. GNI/capita had no clear association with low HSCT activity; however improvement in infrastructure and establishment of EM regional HSCT registry need prioritization.

Old disease, new targets. Part-II, haematological malignancies.

In last two decades newer therapies in cancer treatment have emerged and have opened new horizons. New term of targeted therapy has emerged and for certain malignancies the paradigm has really changed after the introduction of these agents. We have learnt and have seen the outcome of some diseases after the addition of these monoclonal antibodies (MoABs) and tyrosine kinase inhibitors (TKIs). Rituximab a MoAB against CD-20 has really paved its role in the treatment of B-cell lymphomas and become the sort of standard therapy. The TKIs are newer agents available in a pill form and have inhibited many pathways at cellular level which are necessary for cancer development. Imatinib has really changed the prognosis and outcome of chronic myeloid leukemia (CML) remarkably. For those patients who develope intolerance to imatinib or their disease became resistant to the imatinib the newer agents like dasatinib and nilotinib are second line options. The major edge of these newer agents is more potency with low side-effect profile. The major concern remains the cost.

Factors influencing in-hospital length of stay and mortality in cancer patients suffering from febrile neutropenia.

INTRODUCTION: Febrile neutropenia (FN) is a major complication of chemotherapy, costly in terms of morbidity, mortality and associated financial expenditure. The present study was conducted with the goal of highlighting FN as a serious problem in Pakistan, with the longer term objective of improved cancer survival, reduction in length of stay (LOS) in hospital, morbidity, mortality and costs in our existing developing country scenario. METHODS: A cross-sectional descriptive study was conducted on patients, > or =18 years, admitted with FN as a consequence of chemotherapy at a referral hospital in Karachi from 1st September 2006 to 30th April 2007. RESULTS: A total of 80 patients [43 (53.8%) males and 37 (46.2%) females] were selected. The mean age was 47.4 (SD +/-16.6; range 18-79) years. Sixty eight patients (86%) were < or = 65 years, 50% were < or = 50 years. Overall, inhospital mortality was 11%; 4% for patients on granulocyte colony stimulating factor (G-CSF) prophylaxis as against 20% for those without. The cause of death was either pneumonia or septic shock. Mean LOS was 7.53 (SD +/-3.8; range 2-17) days. Hematological malignancies, older age, severity of dehydration, pneumonia and culture positivity were significantly associated with LOS and death. Those above 50 years of age were 1.5 times as likely to be hospitalized longer and > three times as likely to die. Bacteremia conferred a 5-fold and pneumonia an 8-fold increase in the risk of death. CONCLUSION: The results of this study indicate that age, vital instability, dehydration, high creatinine, culture positivity and hematological malignancies are high risk factors in chemotherapy induced FN. Identification of FN risk factors with poor outcomes may help in devising protocols for modified dosage or including GCFs initially. This may help reduce the cost of cancer care as well as mortality and morbidity. Prospective studies of FN in multiple centers in Pakistan may be beneficial in evaluating these risk factors further.
