Hepatitis-associated aplastic anaemia: surveillance of frequency,clinico-haematological features, and demographic distribution at a tertiary care hospital in Pakistan.

OBJECTIVE: We aim to document the frequency of HAAA cases among AA patients presenting at a tertiary care hospital, and to determine the most common agents (viral/drug induced) and Clinico-haematological features among HAAA patients at a tertiary care hospital. Methods: This study was a retrospective review, conducted at a tertiary care hospital in Karachi, Pakistan. RESULTS: A total of 21 patients were included in the study. Hepatitis among the HAAA patients was viral in 17 cases, while 4 were idiopathic. All the patients acquired aplastic anaemia within 3-12 months of the Hepatitis episode and most presented with bleeding, bruises and petechiae. CONCLUSIONS: This study indicates and proves that presence and prevalence of this disease in the Pakistani population is quite significant. Unlike the rest of the world, HAAA in Pakistan is not entirely of unknown aetiology, most of the cases can be associated with one of the Hepatitis viruses.

A prospective evaluation of clinical and functional outcome of single bundle anatomic anterior cruciate ligament reconstruction with hamstrings autograft.

A case series was conducted at the Department of Orthopaedic surgery, Jinnah Postgraduate Medical Centre, Karachi, from July 2016 to June 2018, to evaluate the functional and clinical outcome of arthroscopic anatomic anterior cruciate ligament (ACL) reconstruction with hamstrings autograft. Patients aged 17 years and above with anterior cruciate ligament (ACL) injuries of duration three months or older, diagnosed on history and clinical examination and confirmed on Magnetic Resonance Imaging were prospectively recruited from outpatient department. Patients with multiligamentous injury were excluded. Information on patient's demographics such as age, duration of injury and mechanism of injury were recorded. In addition, graft length and diameter, associated injuries of lateral or medical menisci were noted peroperatively. Patients were followed for a minimum of 12 months. The functional outcomes were assessed through lysholm knee score, and Tegner activity scale. Clinical outcome was assessed with loss of motion in flexion and extension and residual laxity using Lachman test. Paired sample t-test was applied to compare mean scores pre and post-operatively. The study findings reveal that arthroscopic anatomic Anterior Cruciate Ligament reconstruction using quadruple strand hamstring tendon autograft was an effective method of treatment for the ACL-deficient knee with improved clinical and functional status.

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.

Burden of Cardiac Siderosis in a Thalassemia-Major Endemic Population: A Preliminary Report From Pakistan.

OBJECTIVE: To describe the initial experience and demographics of T2* cardiac magnetic resonance-based myocardial-iron quantification of transfusion-dependent thalassemia-major (TM) patients from Pakistan and the correlation with serum ferritin. METHODS: Eligible TM patients presenting between April 2014 and April 2015 to Aga Khan University Hospital, Pakistan, for T2*CMR were included. The severity of myocardial-iron deposition was defined as follows: normal T2*>20 ms, mild-moderate T2*10 to 20 ms, and severe T2*<10 ms. Cardiac symptoms were classified using the NYHA functional classification. Echocardiographic systolic and diastolic functions were performed. Continuous variables were presented as the median (minimum-maximum value). Correlation was measured using the Spearman rank correlation. Multivariate logistic regression was used to determine factors associated with the NYHA functional class. RESULTS: A total of 83 patients (49 male and 34 female) with TM, age 19 (5 to 45) years at presentation for T2*CMR, were reviewed. At presentation, 70% of the patients were classified as NYHA class II or worse. T2*<20 ms was observed in 62.6% of the patients, with 47% showing severe iron deposition (T2<10 ms). No correlation of T2*<20 ms (r=-0.157, P=0.302) and T2*<10 ms (r=-0.128, P=0.464) was observed with serum ferritin. On multivariate analysis, lower T2* values correlated with a worsening NYHA functional class. CONCLUSIONS: There is a high prevalence of severe myocardial iron load in Pakistani TM patients. Serum ferritin did not correlate with T2* values. Lower T2* was the only clinical factor associated with the NYHA functional class.

Clinico-Pathological Profile And Outcomes Of Patients With Polycythaemia Vera, Essential Thrombocythaemia And Idiopathic Myelofibrosis: A Tertiary Care Center Experience From Southern Pakistan.

BACKGROUND: The "Philadelphia Negative Classic Myeloproliferative Neoplasms" include polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF). These three disorders share several clinical and laboratory features including JAK2 V617F mutation. Our objectives were to determine the clinico-pathological profile and outcomes of Pakistani patients with polycythaemia vera (PV), essential thrombocythaemia (ET) and idiopathic myelofibrosis (IMF) in order to have an insight regarding behaviour of these conditions. METHODS: A retrospective analysis of all the cases of PV, ET and IMF diagnosed at our institute from January 1995 to December 2013 was performed. Age, gender, clinical presentation, laboratory investigations, treatment provided and duration of follow-up were included for analysis. Appropriate statistics were utilized for calculation of data. RESULTS: A total of 58 patients were diagnosed as PV, ET or IMF during the study period. Male to female ratio was 1.1:1. Forty five percent (n=27) patients came to medical attention due to abnormal laboratory results, 3 had cerebrovascular events, 3 had pruritus, and 1 patient each with gangrene and Budd-Chiari syndrome. Haemorrhage was not seen in any patient. Sixty percent (n=35) patients were treated with phlebotomy, hydroxyurea and aspirin alone or in combination. None of the patients transformed to myelofibrosis (MF) or myelodysplasia (MDS) during the mean (±SD) follow-up period of 57.2±50 months. One patient with ET transformed to acute myeloid leukaemia 9 years after the diagnosis. CONCLUSIONS: This study demonstrated a relatively more benign form of PV, ET and IMF with lesser frequency of symptoms, good response to treatment and less likelihood of transformation to MF, MDS or AML.

Estimating window period blood donations for human immunodeficiency virus Type 1, hepatitis C virus, and hepatitis B virus by nucleic acid amplification testing in Southern Pakistan.

BACKGROUND: Recently, strategic planning was initiated by the National Blood Transfusion Services Pakistan to improve its blood bank facilities. Emphasis has been placed on appropriate screening of blood products. Located in the southern region, Aga Khan University Hospital is a 700-bed tertiary care academic institute with comprehensive blood banking. Screening of blood donors has been based on verbal screening and serologic testing to date. Additionally, the need of implementing nucleic acid testing (NAT) was considered in 2011 because of an upsurge in hepatitis epidemiology. The aim of this study was to analyze the efficacy of this additional donor screening program and to evaluate the impact of NAT on the yield and residual risk of transfusion-transmissible viral infections. STUDY DESIGN AND METHODS: A total of 42,830 blood donations collected between 2011 and 2012 were screened for routine serologic assays. Only serologically negative donors (n=41,304) were tested for NAT. The frequency of viral infections was evaluated through serologic techniques and NAT yield for viral agents was estimated for computing window period donors. Residual risk per million donors was computed for viral infections in seronegative blood donors. RESULTS: Serologic work-up showed 1571 abnormal screening results in 1526 blood donors with the following results: hepatitis C virus antibodies (anti-HCV; n=708), hepatitis B surface antigen (n=555), human immunodeficiency virus antibodies (anti-HIV; n=29), malaria (n=30), VDRL (n=249), and coinfection (n=45). Thirty-five NAT-reactive samples were identified: HIV-1, one; HCV, 27; and hepatitis B virus (HBV), seven. Incident rates per 10(5) donors were highest for HCV (453.3) followed by HBV (171.5) and HIV (72.2). Calculated residual risk per million donors was highest at 1 in 10,900 for HBV, intermediate at 1 in 13,900 for HCV, and least at 1 in 62,600 for HIV. CONCLUSION: Incidence rates and estimated residual risk indicate that the current risk of transfusion-transmitted viral infections attributable to blood donation is relatively high in this country. The study recommends the parallel use of both serology and NAT screening of donated blood in countries that have high seroprevalence of these viral infections.

Recurrent spontaneous splenic rupture in a patient with congenital factor XIII deficiency.

We describe an unusual presentation of factor XIII (FXIII) deficiency in a 17-year-old boy who was diagnosed with this congenital deficiency at the age of 18 months. He had a history of spontaneous splenic rupture 8 years ago, which was managed conservatively. He now presented with sudden severe abdominal and left shoulder pain for 1 day, with no history of antecedent trauma. He was in shock, and examination revealed diffuse peritonitis. A computed tomography scan showed a grade IV splenic laceration. He was taken as an emergency to the operating room where he was found to have a shattered spleen, and a splenectomy was performed. He received cryoprecipitate transfusions perioperatively. After an uneventful recovery, the patient was discharged. To the best of our knowledge, this is the first described case of a recurrent splenic rupture in a patient with FXIII deficiency.

Real-World Outcomes in Transplant-Ineligible Patients With Newly Diagnosed Multiple Myeloma Treated With Bortezomib/Cyclophosphamide/Dexamethasone and Bortezomib/Lenalidomide/Dexamethasone as Upfront Treatment.

Introduction Multiple myeloma (MM) is a hematological disorder characterized by aberrant multiplication of malignant plasma cells in the bone marrow. The current mainstay of treatment for patients with newly diagnosed MM (NDMM) is a triplet regimen with a proteasome inhibitor, immunomodulatory imide, and dexamethasone. The two most common of these triplet regimens are VLD (bortezomib/lenalidomide/dexamethasone) and VCD (bortezomib/cyclophosphamide/dexamethasone). This study aims to compare the outcomes between these two therapies in transplant-ineligible patients with NDMM. Methods We conducted a retrospective study at the Aga Khan University Hospital in Karachi, Pakistan. All NDMM transplant-ineligible patients either receiving VLD or VCD therapy between January 2015 and December 2022 were included in our study. Hematological parameters before and after treatment were obtained from hospital records. Response to treatment was classified according to the International Myeloma Working Group (IMWG) response criteria as either complete response (CR), very good partial response (VGPR), partial response (PR), minimal response (MR), stable disease (SD), or progressive disease (PD). The response to treatment as well as overall survival (OS) and progression-free survival (PFS) was compared between VCD and VLD therapy. A p-value of 0.05 or less was taken to be statistically significant. Results Twenty (23.8%) patients in the VCD group and 20 (23.0%) in the VLD group underwent complete remission. Seven (8.3%) patients experienced disease progression in the VCD group, while the figure stood at three (3.4%) in the VLD group. There was no statistically significant difference in the overall response rate between the VCD (58; 69.0%) and VLD (70; 80.5%) groups (p=0.086), a difference that was not statistically significant on the Chi-square test. OS was comparable between VCD (69.1 months, 95%CI: 61.3-77.0) and VLD (76.9 months, 95%CI: 69.0-85.0) therapies. Conclusions The study did not identify any statistically significant distinction in the treatment outcomes between the VCD and VLD regimens among NDMM patients ineligible for transplantation. Nevertheless, the study highlights the positive outcomes observed with both treatments in this specific patient cohort. This implies that either regimen could be deemed suitable as a treatment option for patients in low- and middle-income countries. Since both regimens demonstrate comparable effectiveness, assessing the cost-effectiveness of these regimens is crucial. Future research should also explore the economic aspects of the two treatment options.

Deficiency of ADAMTS-13 in pediatric patients with severe sepsis and impact on in-hospital mortality.

BACKGROUND: The enzyme involved in regulating the size of vWF (von Willebrand factor) in plasma is ADAMTS-13 (A disintegrin and metalloprotease with thrombospondin type-1 motives). Deficient proteolysis of ULvWF (ultra large von Willebrand factor) due to reduced ADAMTS-13 activity results in disseminated platelet-rich thrombi in the microcirculation characteristic of thrombotic thrombocytopenic purpura. Reduced ADAMTS-13 has also been observed in severe sepsis and is associated with poor survival. We conducted this study to detect ADAMTS-13 deficiency and its impact on in-hospital mortality in pediatric patients with severe sepsis. METHODS: Pediatric patients diagnosed with severe sepsis were recruited for the study. Baseline clinical characteristics were noted. ADAMTS-13 antigen levels were assayed by ELISA. According to ADAMTS-13 levels, patients were grouped as deficient and non-deficient. Comparison was done with regard to some clinical and biological characteristics and in-hospital mortality between the two groups. RESULTS: A total of 80 patients were enrolled in the study. The median age of the patients was 3.1 years (Range: 0.1-15 years). ADAMTS-13 deficiency with levels less than 350 ng/dl was found in 65% patients. In patients with ADAMTS-13 deficiency, 75.6% had low platelets of less than 150 × 109/L. In-hospital mortality was 42.3% and 35.7% in ADAMTS-13 deficient and non-deficient group, respectively. CONCLUSION: Majority of the pediatric patients admitted to hospital with severe sepsis exhibit ADAMTS-13 deficiency. ADAMTS-13 deficiency might play a role in sepsis-induced thrombocytopenia. More studies are needed to evaluate the role of ADAMTS-13 deficiency on in-hospital mortality.

Haematopoietic Stem Cell Transplant Trends in Pakistan: Activity Survey from Pakistan Bone Marrow Transplant Group.

Pakistan is the fifth most populous country with a population of 225 million and has health expenditure accounting for only 2.8 percent of gross domestic product (GDP). Accordingly, there are a limited number of haematology-oncology and transplant centers in the country. The Pakistan Blood and Marrow Transplant (PBMT) group was established in 2020, and this report is the first activity survey from January 2021 to December 2022 focusing on the trends of matched-related donor, haploidentical, and autologous transplants in a developing country. A total of 12 transplant centers contributed data on the modified PBMT survey form retrospectively and 806 haematopoietic stem cell transplants (HSCTs) were carried out during the study duration. Allogeneic HSCT constituted 595 (73.8%) of all the transplants; this is in stark contrast to Western data, where autologous HSCT accounts for the majority of transplants. ß-thalassemia major and aplastic anemia were the commonest indications for allogeneic HSCT, in contrast to Western data, where acute leukemia is the leading transplant indication. Autologous transplants were more frequently performed for Hodgkin's lymphoma as compared to non-Hodgkin's lymphoma and multiple myeloma. The use of peripheral and bone marrow stem cells was comparable. A myeloablative conditioning regimen was routinely used in patients with acute leukemia. This report provides an insight of HSCT trends in Pakistan which are different from those of Western centers contributing to transplant data from South Asia.

Strategic priorities for hematopoietic stem cell transplantation in the EMRO region.

The World Health Organization-designated Eastern Mediterranean region (EMRO) consists of 22 countries in North Africa and Western Asia with a collective population of over 679 million. The area comprises some of the wealthiest countries per capita income and some of the poorest. The population structure is also unique and contrasts with western countries, with a much younger population. The region sits in the heart of the thalassemia belt. Many countries have a significant prevalence of sickle cell disease, and cancer is on the rise in the region. Therefore, the strategic priorities for the growth and development of hematopoietic stem cell transplantation (HSCT) differ from country to country based on resources, healthcare challenges, and prevalent infrastructure. Thirty-one reporting teams to the Eastern Mediterranean Blood and Marrow Transplantation Group have active HSCT programs in 12 countries; allogeneic transplants outnumber autologous transplants, and the proportion of allotransplants for non-malignant conditions is higher in the EMRO region than in Western Europe and North America. The vast majority (99%) of allotransplants are from matched related donors. Matched unrelated donors and other alternate donor transplants are underutilized. The chance of finding a matched related donor for allografts is higher, with a significant chance of finding matched donors among non-sibling related donors. Reasons for relatively lower rates of transplants compared with other countries are multifactorial. Capacity building, development of newer centers, innovative funding, and better utilization of information technology are required to make transplantation as an accessible modality to more patients. Cost-effectiveness and cost-containment, regulation, and ensuring quality will all be priorities in planning HSCT development in the region.

Endocrine complications in patients of beta thalassemia major in a tertiary care hospital in Pakistan.

OBJECTIVE: To determine the major endocrine complications present in patients of Thalassemia major presenting to a tertiary care center in Karachi, Pakistan. METHODS: Records of all thallasemia major patients at a Haematology Department in a tertiary care hospital of Karachi were retrospectively reviewed from May to August 2009 with specific focus on endocrine data and investigations. The patients' data was recorded in a questionnaire and analyzed using SPSS v.17, frequencies and percentages along with corresponding 95% confidence interval were computed. RESULTS: Our data revealed that a significantly small percentage of those under care received regular endocrine follow-up. Male hypo-gonadal abnormalities had the highest probability; 100% of the tested patients had decreased levels of testosterone, while 95.2% had raised serum creatinine levels. Parathyroid dysfunction was noted in 40% of the patients. Of those screened 29.4% had blood glucose levels in the diabetic range and 11.8% of the tested patients had reduced levels of FT4. CONCLUSION: A high frequency at endocrine dysfunctions seen in thalasaemia patients included: male hypogonadism, parathyroid dysfunction, deranged blood glucose and FT4 levies.

Trends of hematopoietic stem cell transplantation in the Eastern Mediterranean region, 1984-2007.

Hematopoietic stem cell transplantation (HSCT) activity was surveyed in the 9 countries in the World Health Organization Eastern Mediterranean region that reported transplantation activity. Between the years of 1984 and 2007, 7933 transplantations were performed. The number of HSCTs per year has continued to increase, with a plateau in allogeneic HSCT (allo-HSCT) between 2005 and 2007. Overall, a greater proportion of transplantations were allo-HSCT (n = 5761, 77%) compared with autologous HSCT (ASCT) (n = 2172, 23%). Of 5761 allo-HSCT, acute leukemia constituted the main indication (n = 2124, 37%). There was a significant proportion of allo-HSCT for bone marrow failures (n = 1001, 17%) and hemoglobinopathies (n = 885, 15%). The rate of unrelated donor transplantations remained low, with only 2 matched unrelated donor allo-HSCTs reported. One hundred umbilical cord blood transplantations were reported (0.017% of allo-HSCT). Peripheral blood stem cells were the main source of graft in allo-HSCT, and peripheral blood stem cells increasingly constitute the main source of hematopoietic stem cells overall. Reduced-intensity conditioning was utilized in 5.7% of allografts over the surveyed period. ASCT numbers continue to increase. There has been a shift in the indication for ASCT from acute leukemia to lymphoproliferative disorders (45%), followed by myeloma (26%). The survey reflects transplantation activity according to the unique health settings of this region. Notable differences in transplantation practices as reported to the European Group for Blood and Marrow Transplantation over recent years are highlighted.

Aplastic anemia: clinicohaematological features, treatment and outcome analysis.

OBJECTIVE: To determine the clinicohaematological features, treatment and outcome of children diagnosed with aplastic anemia at a single institution. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: The Aga Khan University Hospital, Karachi, from January 1999 till December 2008. METHODOLOGY: Medical records of children aged less than 15 years of age diagnosed with aplastic anemia were reviewed. Clinicohaematological features, treatment and its response to therapy and outcome were recorded. Results were described in percentages. RESULTS: Ninety patients were diagnosed to have aplastic anemia (AA); 65 were male during the study period. Age ranged from 1 to 15 years. Fever in 65 patients (72.2%), pallor in 53 (58.8%), skin bleeding in 49 (54.4%) and epistaxis in 31(34.4%) were the most common and frequent presenting features. Congenital (Fanconi's) anemia was found in 15 (16.6%) and acquired idiopathic in 75 (83.4%) of patients. Very severe aplastic anemia (VSAA) was seen in 29 (32.2%), 26 (28.9%) had severe AA and 17 (18.9%) had moderate AA. Eight patients (8.9%) underwent haematopoietic stem cell transplantation (HSCT), 12 (13.3%) received immunosuppressive therapy (IST) and 70 patients (77.7%) received other and supportive therapy. Five (62.5%) patients showed complete response to HSCT and 3 (37.5%) failed to engraft. IST showed complete response in 3 (25%), partial response in 5 (41.6%) and no response in 4 (33.3%). Twenty two patients (24.4%) expired either due to infection in 16 (72.7%, fungal in 6, bacterial in 10) and intracranial haemorrhage in 6 (27.3%) cases. CONCLUSION: Majority of cases with AA were acquired and idiopathic in etiology. VSAA and SAA were frequent. Response to HSCT and IST was sub-optimal.

Transplant in Aplastic Anemia Using Combined Granulocyte Colony-Stimulating Factor Primed Blood and Bone Marrow Stem Cells: A Retrospective Analysis.

INTRODUCTION: Aplastic anemia (AA) is characterized by diminished hematopoietic precursors in the bone marrow, most often due to injury to the pluripotent stem cell. In Pakistan, AA is not uncommon, and allogeneic hematopoietic stem cell transplant remains the only curative option for these patients. OBJECTIVE: The objective of this study was to determine the transplant outcome of combined granulocyte colony-stimulating factor (G-CSF) primed blood and bone marrow grafts in adult and pediatric patients with AA. METHODS: We retrospectively collected the data of all transplant procedures performed from 2004 to 2019 at Aga Khan University in Karachi, Pakistan. Variables analyzed included age, sex, type of stem cells used, conditioning regimens, and overall survival for patients undergoing transplant in AA. RESULTS: A total of 351 transplants were performed during the study period. Out of these, 239 were allogeneic transplants, whereas 112 were autologous procedures. We performed 70 transplants for AA during the study period, of which 52 were male patients and 18 were female patients. The median age ± standard deviation (SD) was 17.5 ± 9.4 years (range, 2-43 years). Cyclophosphamide/antithymocyte globulin (ATG) was used as a conditioning regimen in 65 patients, while ATG/cyclophosphamide/fludarabine was used in 5 patients. In 60 patients, a combination of G-CSF primed blood and bone marrow stem cells were used. The mean CD34 count was 5.2 × 106/kg. Graft-vs-host disease (GVHD) prophylaxis was done with cyclosporine and methotrexate. All patients received standard infection prophylaxis. Engraftment was achieved in 86% of patients. The median day of myeloid engraftment was 15 (range, 10-22 days). Chronic GVHD was present in 3 patients while 4 had acute GVHD. The overall survival was 71.2% (median duration of 80 months). The main cause of mortality was gram-negative sepsis. CONCLUSION: A combination of blood and bone marrow stem cells results in early engraftment with decreased frequency of GVHD in AA. The overall survival was comparable to international literature.

Outcomes of patients with double/triple expressor diffuse large B-cell lymphoma (DLBCL) treated with R-DA-EPOCH/R-CHOP: A single-center experience.

In Pakistan 76.4% of all NHLs to be diagnosed as DLBCLs. The survival of R-CHOP is better compared to the DA-REPOCH treatment regimen. A prospective follow-up study was conducted with 113 patients to study the outcomes of treatment. Multivariable cox-proportional hazard model was used to estimate the hazard ratios in patients receiving these treatment regimens considering p-value ≤0.05 significant. The survival rate among double/triple expressor lymphoma patients received R-DA-EPOCH was 82.8%, and 83.3% received R-CHOP. For double/triple expressor lymphoma patients received R-DA-EPOCH. The findings of our study demonstrated that the survival rate in both R-CHOP and R-DA-EPOCH is mostly similar.

Diagnosis and Management of Diffuse Large B-Cell Lymphoma: Society of Medical Oncology, Pakistan Society of Hematology, and Pakistan Society of Clinical Oncology Joint Clinical Practice Guideline.

Diffuse large B-cell lymphoma (DLBCL) is the commonest non-Hodgkin lymphoma encountered by hematopathologists and oncologists. Management guidelines for DLBCL are developed and published by countries with high income and do not cater for practical challenges faced in resource-constrained settings. This report by a multidisciplinary panel of experts from Pakistan is on behalf of three major national cancer societies: Society of Medical Oncology Pakistan, Pakistan Society of Hematology, and Pakistan Society of Clinical Oncology. The aim is to develop a practical and standardized guideline for managing DLBCL in Pakistan, keeping in view local challenges, which are similar across most of the low- and middle-income countries across the globe. Modified Delphi methodology was used to develop consensus guidelines. Guidelines questions were drafted, and meetings were convened by a steering committee to develop initial recommendations on the basis of local challenges and review of the literature. A consensus panel reviewed the initial draft recommendations and rated the guidelines on a five-point Likert scale; recommendations achieving more than 75% consensus were accepted. Resource grouping initially suggested by Breast Health Global Initiative was applied for resource stratification into basic, limited, and enhanced resource settings. The panel generated consensus ratings for 35 questions of interest and concluded that diagnosis and treatment recommendations in resource-constrained settings need to be based on available resources and management expertise.

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.

Successful use of rituximab in Evans syndrome and refractory immune thrombocytopenic purpura.

Immune cytopenias are mediated by auto-antibodies produced by B-lymphocytes. Conventional treatment of immune-mediated haematological disorders includes immunosuppression with steroids and other immune modulating therapies and in some refractory cases, splenectomy. Response rates to conventional and second-line agents are variable and a proportion of patients require lifelong immunosuppression to maintain the disease in remission. Rituximab, an anti- CD 20 monoclonal antibody has gained widespread acceptance in the management of B-cell malignancies. Additionally, it has been used to treat the disorders associated with autoantibody production. We report herein the successful use of Rituximab in the treatment of two patients with autoimmune cytopenias one had Evan's syndrome and other had refractory immune thrombocytopenic purpura. Both of these patients are still in remission at 16 and 25 months following treatment.
