Background: With the emergence of tyrosine kinase inhibitors and the incorporation of stringent measurable residual disease (MRD) monitoring, risk stratification for BCR-ABL1-positive acute lymphoblastic leukemia (ALL) patients has changed significantly. However, whether this monitoring can replace conventional risk factors in determining whether patients need allogeneic stem cell transplantation is still unclear. This study aimed to determine the impact of BCR-ABL1 monitoring on the outcome of patients with BCR-ABL1-positive ALL after allogeneic stem cell transplantation. Methods: We retrospectively analyzed the survival outcome of patients with BCR-ABL1-positive ALL based on the quantification of BCR-ABL1 at 3 timepoints: the end of induction (timepoint 1), post-consolidation week 16 (timepoint 2), and the end of treatment for patients who were either transplant-eligible or non-transplant eligible (timepoint 3). Results: From 2006 to 2018, a total of 96 patients newly diagnosed with BCR-ABL1-positive ALL were treated with chemotherapy and tyrosine kinase inhibitors. Thirty-eight (41.3%) patients achieved complete remission, and 33 patients underwent allogeneic stem cell transplantation. Our data showed that pre-transplant MRD monitoring by real-time quantitative polymerase chain reaction had the highest correlation with survival in patients with BCR-ABL1-positive ALL, especially for those who underwent allogeneic stem cell transplantation. Conclusion Patients without MRD pre-transplantation had superior survival compared with those who had MRD, and they had excellent long-term outcomes after allogeneic stem cell transplantation.

Introduction: Malaysia is endemic for leptospirosis with increasing incidence recorded over the years. Perak has recorded one of the highest incidence and mortality of leptospirosis since 2004. Methods: This is a retrospective study of confirmed leptospirosis cases in Larut, Matang and Selama (LMS) district in Perak reported in 2016. The demographic, clinical presentation, laboratory result and clinical outcomes data were analysed and presented. Results: Forty-two patients with confirmed diagnosis of leptospirosis were included into the study. Majority of patients were males and Malays. The case fatality rate was 14.3%. Patients with leptospirosis present with variable clinical presentations and are commonly seen with coinfection. Patients 70-year-old and older, have clinical presentations suggestive of organ dysfunction and require intensive care are associated with higher mortality. Conclusion: Leptospirosis is endemic in LMS district of Perak with high incidence and case fatality rate. The clinical presentation of leptospirosis is variable. Co-infection of leptospirosis with other acute febrile illness is common. Patients presenting with symptoms and signs of organ dysfunctions or require intensive care are associated with an increased odds of death.

Introduction/Objective: The management of potential treatment-related complications and bleeding events in haemophilia is challenging in developing countries. Providing optimal care among these patients improve their quality of life (QOL) and life expectancy. This study explores the demographic characteristics and treatment outcome in a major haemophilia treatment centre in Malaysia. Materials and Methods: A total of 260 patients were recruited in this retrospective cross-sectional analysis. Clinical data, including treatment regimens and outcome, were collected and analysed. Results: A total of 211 patients were diagnosed with haemophilia A (HA) (severe disease, 72.5%) and 49 patients had haemophilia B (HB) (severe disease, 65.3%). The median age was 31 (IQR;2-84) years. Majority of the patients had at least one episode of musculoskeletal bleeding since diagnosis. The mean annual bleeding event (ABE) was 4.91 (SD±6.07) in 2018. Target joints were identified in 80.4% of the patients. Chronic arthropathy and synovitis collectively accounted for more than half of the musculoskeletal complications. 30.1% of the patients had contracted hepatitis C with less than half received treatment. Thirty-one patients (16.8%) with severe haemophilia developed inhibitor and 12 patients successfully underwent immune tolerance induction. More than three-quarters of the severe haemophilia patients were treated with factor concentrate prophylaxis. The mean prophylaxis dose for HA and HB were 41.3 (SD±19.1) and 48.6 (SD±21.5) IU/kg/week, respectively. In patients with severe disease, prophylaxis significantly reduced the ABE (5.45,9.03;p=0.005). Conclusion: The importance of utilising a low to moderate dose regimen as prophylaxis in haemophilic patients is highlighted in our study. Future studies should include QOL assessment will further improve the management in haemophilia.
