    Cytomegalovirus (CMV) retinitis occurs predominantly in Human Immunodeficiency Virus (HIV) -infected patients. It was also reported in HIV-seronegative patients with systemic autoimmune disorder requiring systemic immunosuppression, organ or bone marrow transplantation, haematological or breast malignancy receiving chemotherapy, ocular diseases following intraocular or periocular corticosteroid injection, diabetes mellitus and Good syndrome. However, CMV retinitis in patients with concurrent dermatomyositis and malignancy has not been previously reported. It has not been reported in cancer other than haematological or breast malignancy, or in cancer patient prior to chemotherapy. We report a case of 40-year-old HIV-seronegative woman with underlying dermatomyositis and lung malignancy who developed right CMV retinitis which relapsed after recommencement of immunosuppressant. Both episodes of CMV retinitis were successfully treated after taken her immunocompromised state into consideration.

    The first cooperative study of the Asian Pacific bone marrow transplantation group included 75 patients with early leukemia who received human leukocyte antigen-matched sibling bone marrow transplants and were randomized into granulocyte colony-stimulating factor and control groups. The selected patients were registered from 10 centers in six countries and areas within Asia (Beijing, Taipei, Hong Kong, Japan, Korea, and Malaysia). The incidence of grades II-IV acute graft-vs.-host disease was 22.2%, and the 2-year survival rate was 62.7%. The period of protective isolation (27.1-66.7 days), period of hospitalization (38.6-130.5 days), and medical costs for 4 months (US $10,300-US $80,803) varied considerably. Good cooperation, i.e., low rate of protocol violation or rapid and precise presentation of case reports, was obtained.

    Gingival overgrowth is a well-recognized unwanted effect associated with three major drugs / drug groups - phenytoin, cyclosporine and the calcium channel blockers. Cyclosporine is the first-choice immunosuppressant for preventing allograft rejection in patients who have received organ or bone marrow transplants. This report aims to highlight a case in which the patient on cyclosporine therapy had also contracted Hepatitis C virus infection.

  5. Approaches to deriving Schwann cells from human bone marrow for neural tube regeneration in a clinical setting
    Hidayah HN, Mazzre M, Ng AM, Ruszymah BH, Shalimar A
    Med J Malaysia, 2008 Jul;63 Suppl A:39-40.
    PMID: 19024973
    Bone marrow derived Mesenchymal stem cells (MSCs) were evaluated as an alternative source for tissue engineering of peripheral nerves. Human MSCs were subjected to a series of treatment with a reducing agent, retinoic acid and a combination of trophic factors. This treated MSCs differentiated into Schwann cells were characterized in vitro via flow cytometry analysis and immunocytochemically. In contrast to untreated MSCs, differentiated MSCs expressed Schwann cell markers in vitro, as we confirmed by flow cytometry analysis and immunocytochemically. These results suggest that human MSCs can be induced to be a substitute for Schwann cells that may be applied for nerve regeneration since it is difficult to grow Schwann cells in vitro.

  6. Fulltext The potential of intra-articular injection of chondrogenic-induced bone marrow stem cells to retard the progression of osteoarthritis in a sheep model
    Al Faqeh H, Nor Hamdan BM, Chen HC, Aminuddin BS, Ruszymah BH
    Exp Gerontol, 2012 Jun;47(6):458-64.
    PMID: 22759409 DOI: 10.1016/j.exger.2012.03.018
    In recent years, the use of bone marrow mesenchymal stem cell (BMSC) implantation has provided an alternative treatment for osteoarthritis. The objective of this study is to determine whether or not an intra-articular injection of a single dose of autologous chondrogenic induced BMSC could retard the progressive destruction of cartilage in a surgically induced osteoarthritis in sheep. Sheep BMSCs were isolated and divided into two groups. One group was cultured in chondrogenic media containing (Ham's F12:DMEM, 1:1) FD+1% FBS+5 ng/ml TGFβ3+50 ng/ml IGF-1 (CM), and the other group was cultured in the basal media, FD+10% FBS (BM). The procedure for surgically induced osteoarthritis was performed on the donor sheep 6 weeks prior to intra-articular injection into the knee joint of a single dose of BMSC from either group, suspended in 5 ml FD at density of 2 million cells/ml. The control groups were injected with basal media, without cells. Six weeks after injection, gross evidence of retardation of cartilage destruction was seen in the osteoarthritic knee joints treated with CM as well as BM. No significant ICRS (International Cartilage Repair Society) scoring was detected between the two groups with cells. However macroscopically, meniscus repair was observed in the knee joint treated with CM. Severe osteoarthritis and meniscal injury was observed in the control group. Interestingly, histologically the CM group demonstrated good cartilage histoarchitecture, thickness and quality, comparable to normal knee joint cartilage. As a conclusion, intra-articular injection of a single dose of BMSC either chondrogenically induced or not, could retard the progression of osteoarthritis (OA) in a sheep model, but the induced cells indicated better results especially in meniscus regeneration.

    Ng MH, Aminuddin BS, Tan KK, Tan GH, Sabarul Afian M, Ruszymah BH
    Med J Malaysia, 2004 May;59 Suppl B:41-2.
    PMID: 15468809
    Bone marrow stem cells (BMSC), known for its multipotency to differentiate into various mesenchymal cells such as chodrocyte, osteoblasts, adipocytes, etc, have been actively applied in tissue engineering. BMSC have been successfully isolated from bone marrow aspirate and bone marrow scraping from patients of various ages (13-56 years) with as little as 2ml to 5ml aspirate. BMSC isolated from our laboratory showed the presence of a heterogenous population that showed varying prevalence of surface antigens and the presence of telomerase activity albeit weak. Upon osteogenic induction, alkaline phosphatase activity and mineralization activity were observed.

    Aplastic anemia, life-threatened disease, is a hematologic disorder characterised by bone marrow hypoplasia. Multiple modalities such as bone marrow transplantation and immunosuppression treatment have been proposed to ameliorate this entity, however it remains ineffective. Sambucus, a group of herb plants, possesses a broad spectrum of medicinal properties such as antioxidant, insulin-like activity, anticancer and antiviral. However, the study about its activity toward aplastic anemia incidence is based on limited data. Thus, the research aim of this study was to evaluate the immunomodulatory activities of Sambucus javanica in chloramphenicol-induced anemia aplastic mouse model. In this present study, BALB/c mice were administrated with chloramphenicol (CMP) to induce aplastic anemia then followed by S. javanica extracts treatment. Additionally, cellular and molecular aspects were evaluated by flow cytometry and Hematoxylin-Eosin staining. Further analysis showed that S. javanica extracts could promote the population number of regulatory T-cells and naive cytotoxic T-cells. Moreover, those extract also reduced the inflammation and necrotic incidence in CMP-induced mouse aplastic anemia model. Together, these results suggest that S. javanica has therapeutically effect to aplastic anemia by altering the immune system as an immunomodulatory agent.

    MyJurnal
    The thalassaemias are the commonest single gene disorders amongst the inherited diseases. In Malaysia, there are an estimated 2200 transfusion dependent thalassaemia patients. With a carrier rate of 3-5%, 120-340 new cases of thalassaemia are expected to be born each year. The reference treatments for these patients are regular blood transfusions and iron chelation therapy. With optimal management, these patients are able to survive into the third or fourth decade of life and most importantly avoid the complications related to transfusions and iron overload. The use of desferal locally is still limited to only those who can afford i.e. about 30% of the cases. Treatment for some of the complications such as hepatitis C, diabetes mellitus, growth impairment and pubertal delay, are now available. Curative treatment approaches like bone marrow transplantation have now become standard treatment for eligible cases whilst cord blood transplantation may yet offer hope for those who are without compatible sibling donors. Research on globin gene therapy looks very promising but will probably take some time to deliver. Hb F switching is a very novel idea but so far the results are mainly anecdotal. Finally, the strive for optimal management of thalassaemia must come hand in hand with a prevention programme to achieve a reduction of new cases.

  10. Articular cartilage regeneration with autologous marrow aspirate and hyaluronic Acid: an experimental study in a goat model
    Saw KY, Hussin P, Loke SC, Azam M, Chen HC, Tay YG, et al.
    Arthroscopy, 2009 Dec;25(12):1391-400.
    PMID: 19962065 DOI: 10.1016/j.arthro.2009.07.011
    PURPOSE: The purpose of the study was to determine whether postoperative intra-articular injections of autologous marrow aspirate (MA) and hyaluronic acid (HA) after subchondral drilling resulted in better cartilage repair as assessed histologically by Gill scoring.
    METHODS: In a goat model we created a 4-mm full-thickness articular cartilage defect in the stifle joint (equivalent to 1.6 cm in the human knee) and conducted subchondral drilling. The animals were divided into 3 groups: group A (control), no injections; group B (HA), weekly injection of 1 mL of sodium hyaluronate for 3 weeks; and group C (HA + MA), similar to group B but with 2 mL of autologous MA in addition to HA. MA was obtained by bone marrow aspiration, centrifuged, and divided into aliquots for cryopreservation. Fifteen animals were equally divided between the groups and sacrificed 24 weeks after surgery, when the joint was harvested, examined macroscopically and histologically.
    RESULTS: Of the 15 animals, 2 from group A had died of non-surgery-related complications and 1 from group C was excluded because of a joint infection. In group A the repair constituted mainly scar tissue, whereas in group B there was less scar tissue, with small amounts of proteoglycan and type II collagen at the osteochondral junction. In contrast, repair cartilage from group C animals showed almost complete coverage of the defect with evidence of hyaline cartilage regeneration. Histology assessed by Gill scoring was significantly better in group C with 1-way analysis of variance yielding an F statistic of 10.611 with a P value of .004, which was highly significant.
    CONCLUSIONS: Postoperative intra-articular injections of autologous MA in combination with HA after subchondral drilling resulted in better cartilage repair as assessed histologically by Gill scoring in a goat model.
    CLINICAL RELEVANCE: After arthroscopic subchondral drilling, this novel technique may result in better articular cartilage regeneration.

  11. Fulltext Minimal residual disease-guided treatment deintensification for children with acute lymphoblastic leukemia: results from the Malaysia-Singapore acute lymphoblastic leukemia 2003 study
    Yeoh AE, Ariffin H, Chai EL, Kwok CS, Chan YH, Ponnudurai K, et al.
    J Clin Oncol, 2012 Jul 1;30(19):2384-92.
    PMID: 22614971 DOI: 10.1200/JCO.2011.40.5936
    PURPOSE: To improve treatment outcome for childhood acute lymphoblastic leukemia (ALL), we designed the Malaysia-Singapore ALL 2003 study with treatment stratification based on presenting clinical and genetic features and minimal residual disease (MRD) levels measured by polymerase chain reaction targeting a single antigen-receptor gene rearrangement.
    PATIENTS AND METHODS: Five hundred fifty-six patients received risk-adapted therapy with a modified Berlin-Frankfurt-Münster-ALL treatment. High-risk ALL was defined by MRD ≥ 1 × 10(-3) at week 12 and/or poor prednisolone response, BCR-ABL1, MLL gene rearrangements, hypodiploid less than 45 chromosomes, or induction failure; standard-risk ALL was defined by MRD ≤ 1 × 10(-4) at weeks 5 and 12 and no extramedullary involvement or high-risk features. Intermediate-risk ALL included all remaining patients.
    RESULTS: Patients who lacked high-risk presenting features (85.7%) received remission induction therapy with dexamethasone, vincristine, and asparaginase, without anthracyclines. Six-year event-free survival (EFS) was 80.6% ± 3.5%; overall survival was 88.4% ± 3.1%. Standard-risk patients (n = 172; 31%) received significantly deintensified subsequent therapy without compromising EFS (93.2% ± 4.1%). High-risk patients (n = 101; 18%) had the worst EFS (51.8% ± 10%); EFS was 83.6% ± 4.9% in intermediate-risk patients (n = 283; 51%).
    CONCLUSION: Our results demonstrate significant progress over previous trials in the region. Three-drug remission-induction therapy combined with MRD-based risk stratification to identify poor responders is an effective strategy for childhood ALL.

    In the setting of transplantation and chronic hepatitis B viral infection there is a unique histological feature termed cholestatic fibrosing hepatitis. The use of nucleoside analogues in the treatment of this condition has been successful. We describe a case of cholestatic fibrosing hepatitis, which occurred after intense immunosuppression for graft versus host disease in a patient with bone marrow transplantations. She was commenced on lamivudine therapy and showed good clinical, biochemical and virological response. However she succumbed due to sepsis.

    Hematology, 2001;6(5):337-9.
    PMID: 27405528 DOI: 10.1080/10245332.2001.11746588
    Nocardia infection is rare in bone marrow transplant (BMT) recipients with less than 30 cases reported in the literature [1-4]. The majority of the cases occurred late in the post-transplant period. Common clinical presentations included formation of widespread and multiple abscesses. Bone marrow hypoplasia is an uncommon finding. We describe the first case of nocardiosis, diagnosed at day 100 after non-myeloablative allogeneic peripheral blood stem cell transplantation, presenting as pancytopenia and hypocellular marrow. Eradication of the infection with antibiotics resulted in complete hematological recovery.

  16. Dental abnormalities of a long-term survivor of a childhood hematological malignancy: literature review and report of a case
    Zarina RS, Nik-Hussein NN
    J Clin Pediatr Dent, 2005;29(2):167-74.
    PMID: 15719924
    The treatment of haematological malignancy is multimodal and involves chemotherapy, radiotherapy and/or bone marrow transplants. With the advancement in cancer therapy, there is an increase in the survival of many children with childhood haematological malignancy. In addition, the late effect of the oncology treatment to the orofacial and dental development becomes significant in terms of the potential clinical impact that may affect the quality of life of the survivor. The severity of the long-term effects is dependent on the age of the child at initiation of treatment and whether chemotherapy is combined with radiation or not. The dental treatment may become more complex if the patient requires advanced restorative dental care and the roots malformation may complicate orthodontic treatment. Therefore these patients may require a scheduled careful preventive programme, long-term follow up, with prophylactic treatment and intervention at appropriate time to minimize the consequences of the disease and the given therapy.

  17. Chediak-Higashi syndrome: a case report
    Jayaranee S, Menaka N
    Malays J Pathol, 2004 Jun;26(1):53-7.
    PMID: 16190108
    A 5-month-old Chinese male infant was referred to the University Hospital, Kuala Lumpur for persistent fever, generalised rash and abdominal distension. Clinically he was suspected to have haemophagocytic lymphohistiocytosis. Haematological findings including the presence of several abnormal giant granules in neutrophils and single large azurophilic granules in many lymphocytes and monocytes in the peripheral blood established the diagnosis of Chediak-Higashi syndrome. The patient responded to allogeneic bone marrow transplant. This paper discusses the characteristic features, clinical course and management of this rare disorder. We suggest that peripheral blood film examination for the abnormal giant granules in granulocytes is an essential investigation in all young children with frequent recurrent infections or who are suspected to have virus-associated haemophagocytic syndrome or familial haemophagocytic lymphohistiocytosis.

    PMID: 15544044
    Conventional therapies for severe ischemic heart disease are limited in applicability. While several angiogenesis researches have shown novel efficacy, safety and feasibility for clinical use, recently we have started the clinical trial of a sole cell therapy using autologous bone marrow mononuclear cells transplantation targeted into ischemic hibernating myocardium. Here, we review the background of bone marrow cell research and introduce therapeutic angiogenesis for severe ischemic heart disease by autologous bone marrow cells transplantation.

  19. Fulltext Transplantation of human bone marrow mesenchymal stromal cells reduces liver fibrosis more effectively than Wharton's jelly mesenchymal stromal cells
    Rengasamy M, Singh G, Fakharuzi NA, Siddikuzzaman, Balasubramanian S, Swamynathan P, et al.
    Stem Cell Res Ther, 2017 06 13;8(1):143.
    PMID: 28610623 DOI: 10.1186/s13287-017-0595-1
    BACKGROUND: Mesenchymal stromal cells (MSCs) from various tissues have shown moderate therapeutic efficacy in reversing liver fibrosis in preclinical models. Here, we compared the relative therapeutic potential of pooled, adult human bone marrow (BM)- and neonatal Wharton's jelly (WJ)-derived MSCs to treat CCl4-induced liver fibrosis in rats.

    METHODS: Sprague-Dawley rats were injected with CCl4 for 8 weeks to induce irreversible liver fibrosis. Ex-vivo expanded, pooled human MSCs obtained from BM and WJ were intravenously administered into rats with liver fibrosis at a dose of 10 × 106 cells/animal. Sham control and vehicle-treated animals served as negative and disease controls, respectively. The animals were sacrificed at 30 and 70 days after cell transplantation and hepatic-hydroxyproline content, histopathological, and immunohistochemical analyses were performed.

    RESULTS: BM-MSCs treatment showed a marked reduction in liver fibrosis as determined by Masson's trichrome and Sirius red staining as compared to those treated with the vehicle. Furthermore, hepatic-hydroxyproline content and percentage collagen proportionate area were found to be significantly lower in the BM-MSCs-treated group. In contrast, WJ-MSCs treatment showed less reduction of fibrosis at both time points. Immunohistochemical analysis of BM-MSCs-treated liver samples showed a reduction in α-SMA+ myofibroblasts and increased number of EpCAM+ hepatic progenitor cells, along with Ki-67+ and human matrix metalloprotease-1+ (MMP-1+) cells as compared to WJ-MSCs-treated rat livers.

    CONCLUSIONS: Our findings suggest that BM-MSCs are more effective than WJ-MSCs in treating liver fibrosis in a CCl4-induced model in rats. The superior therapeutic activity of BM-MSCs may be attributed to their expression of certain MMPs and angiogenic factors.
