Fulltext Predictive value of thrombocytopaenia in the diagnosis of dengue infection in outpatient settings

Tong SF, Aziz NA, Chin GL

Med J Malaysia, 2007 Dec;62(5):390-3.
PMID: 18705473 MyJurnal

Thrombocytopaenia is often relied upon as an important criterion for the diagnosis of dengue infection among patients presenting with an acute non-specific febrile illness. This study was aimed to assess usefulness of thrombocytopaenia in the diagnosis of acute dengue virus infection. This was a clinic based prospective cohort study from May to November 2003. Consecutive patients presenting with acute non-specific febrile illness of less than two weeks were selected from two urban primary care centres. We did full blood count examination (FBC) on the day of visit and dengue serology on day five of illness for all patients enrolled. We repeated the FBC examination for patients who had initial normal platelet counts. Thrombocytopaenia was defined as platelet count < 150 X 10(9)/L. Eighty-seven patients enrolled in the study. Complete data was available for 73 patients. The prevalence of acute dengue virus infection was 27.6%. The sensitivity and specificity were 88% and 71% respectively. The likelihood of acute dengue infection in the presence of thrombocytopaenia was 2.52 and likelihood of not having dengue infection in normal platelet count patients was 5.22. Thrombocytopaenia has fair predictive value in diagnosing acute dengue virus infection. It was more useful to exclude than to diagnose dengue infection.

Fulltext The correlation between cytopenia and esophageal varices in patients with liver cirrhosis

Gue CS, Yap CK, Ng HS

Med J Malaysia, 2004 Dec;59(5):604-8.
PMID: 15889562

This retrospective study analysed the case records of 200 patients in the Department of Gastroenterology, Singapore General Hospital from February 2000 to January 2001 who had liver cirrhosis and underwent gastroscopy for the detection of varices. The aim of this study was to determine any relationship between leucopenia, thrombocytopenia and the occurrence of esophageal varices in a cirrhotic population. Our results showed that the diagnostic yield of varices grade 2 and 3 was 6.3% if platelet count was > 150,000/mm3, 25% if platelet count was 100,000 to 150,000/mm3, 38.9% if platelet count was 50,000-99,000/mm3 and 100% if platelet count was <50,000/mm3. Similarly, the diagnostic yield of varices grade 2 and 3 was 19.4% if total white count was > 4,000/mm3, 66.7% if total white count was 3,000- 4,000/mm3 and 94.8% if total white count was < 3,000/mm5. We conclude that thrombocytopenia and leucopenia can be used to stratify risk for occurrence of esophageal varices in cirrhotic patients and gastroscopy will have a high yield for varices when platelet count is < 150,000/mm3 or total white is < 4,000/mm.

Fulltext Mortality patterns in Malaysian systemic lupus erythematosus patients

Yeap SS, Chow SK, Manivasagar M, Veerapen K, Wang F

Med J Malaysia, 2001 Sep;56(3):308-12.
PMID: 11732075

A retrospective analysis of the case records of 494 systemic lupus erythematosus (SLE) patients under follow-up at University Hospital, Kuala Lumpur during 1976-1990 was performed. Overall mortality was 20.2% (100 patients). The causes of death were infection (30%), renal (15%), respiratory (14%), neurological (5%), cardiovascular (7%), other causes (2%) and unknown (27%). Active SLE was a contributing factor in 19% of the deaths. The patients who died had significantly more renal disease, neurological disease, serositis or thrombocytopenia by the end of the first year of disease compared to the survivors. As in other series, infection and active SLE remain important causes of death.

Fulltext Anticardiolipin antibody isotype profile in lupus nephritis--a cross sectional survey

Azizah MR, Loo CS, Zulkifli MN, Shahnaz M, Zaki M, Nasuruddin BA

Med J Malaysia, 1998 Sep;53(3):257-62.
PMID: 10968163

Thirty-six patients with lupus nephritis (LN) attending the Nephrology Clinic, Hospital Kuala Lumpur were studied for the prevalence of anticardiolipin antibody (ACA) isotypes (IgG and IgM) and other associated antibodies, antinuclear antibody (ANA) and anti-ds DNA antibody and to determine the possible association between serological and clinical parameters. The study population consisted of 20 (55.6%) Malays, 15 (41.7%) Chinese and 1 (2.8%) Indian with a mean age of 31.4 +/- 11.3 years, range 14 to 60 years. The female to male ratio was 11:1. The average time between diagnosis and blood sampling was 4.4 years (range 0.25 to 15 years). Increased ACA levels were found in 20 (55.6%) patients where raised IgG ACA and IgM ACA were observed in 20 (55.6%) and 2 (5.6%) cases respectively. ANA and anti-ds DNA antibodies were detected in 22 (61.1%) and 4 (11.1%) individuals respectively, with the majority (82%) showing a speckled pattern of nuclear staining. However, neither the IgM ACA nor IgG ACA showed any significant association with thrombosis or any other clinical parametres. Our preliminary study indicates that ACA is a frequent finding in lupus nephritis and that the IgG isotype is more prevalent.

Fulltext Classifying dengue: a review of the difficulties in using the WHO case classification for dengue haemorrhagic fever

Bandyopadhyay S, Lum LC, Kroeger A

Trop Med Int Health, 2006 Aug;11(8):1238-55.
PMID: 16903887 DOI: 10.1111/j.1365-3156.2006.01678.x

BACKGROUND: The current World Health Organisation (WHO) classification of dengue includes two distinct entities: dengue fever (DF) and dengue haemorrhagic fever (DHF)/dengue shock syndrome; it is largely based on pediatric cases in Southeast Asia. Dengue has extended to different tropical areas and older age groups. Variations from the original description of dengue manifestations are being reported.
OBJECTIVES: To analyse the experience of clinicians in using the dengue case classification and identify challenges in applying the criteria in routine clinical practice.
METHOD: Systematic literature review of post-1975 English-language publications on dengue classification.
RESULTS: Thirty-seven papers were reviewed. Several studies had strictly applied all four WHO criteria in DHF cases; however, most clinicians reported difficulties in meeting all four criteria and used a modified classification. The positive tourniquet test representing the minimum requirement of a haemorrhagic manifestation did not distinguish between DHF and DF. In cases of DHF thrombocytopenia was observed in 8.6-96%, plasma leakage in 6-95% and haemorrhagic manifestations in 22-93%. The low sensitivity of classifying DHF could be due to failure to repeat the tests or physical examinations at the appropriate time, early intravenous fluid therapy, and lack of adequate resources in an epidemic situation and perhaps a considerable overlap of clinical manifestations in the different dengue entities.
CONCLUSION: A prospective multi-centre study across dengue endemic regions, age groups and the health care system is required which describes the clinical presentation of dengue including simple laboratory parameters in order to review and if necessary modify the current dengue classification.

Aspects of obstetrical defibrination in West Malaysia

White JC, Chan LK, Lau KS, Sen DK

J Trop Med Hyg, 1976 Jun;79(6):132-6.
PMID: 1084931

Five patients illustrate various aspects of obstetrical defibrination in West Malaysia, resulting from exaggeration of changes in fibrinolytic-coagulation equilibrium that occur at delivery. Hypofibrinogenaemia and fibrinolysis may occur in association or either feature predominate. These patients are from a population in which a variety of genetic and environmental factors may interact, e.g. abnormal haemoglobins, cold agglutinins, viral and other infections, introducing additional complications.

Fulltext Dengue haemorrhagic fever with unusual prolonged thrombocytopaenia

Kamil SM, Mohamad NH, Narazah MY, Khan FA

Singapore Med J, 2006 Apr;47(4):332-4.
PMID: 16572249

We describe a case of dengue haemorrhagic fever with prolonged thrombocytopaenia. A 22-year-old Malay man with no prior illness presented with a history of fever and generalised macular rash of four days duration. Initial work-up suggested the diagnosis of dengue haemorrhagic fever based on thrombocytopaenia and positive dengue serology. Patient recovered from acute illness by day ten, and was discharged from the hospital with improving platelet count. He was then noted to have declining platelet count on follow-up and required another hospital admission on day 19 of his illness because of declining platelet count. The patient remained hospitalised till day 44 of his illness and managed with repeated platelet transfusion and supportive care till he recovered spontaneously.

Recurrent spontaneous subdural hematoma secondary to immune thrombocytopenia in a patient with overlap syndrome

Goh KG, Ong SG

Lupus, 2015 Jan;24(1):90-3.
PMID: 25305213 DOI: 10.1177/0961203314554248

Patients with autoimmune connective tissue disease may manifest as overlap syndrome with features of systemic lupus erythematosus (SLE), systemic sclerosis, rheumatoid arthritis and myositis. Those presenting with active SLE can present with immune thrombocytopenia (IT) and may be complicated with subdural hematoma which, though rare, is potentially life-threatening. We report here a patient with overlap syndrome who had recurrent spontaneous subdural hematoma due to severe thrombocytopenia which did not respond to corticosteroids and azathioprine. Her platelet count became normal with three doses of low-dose intravenous cyclophosphamide (IV CYC) given at 3-weekly intervals. She remained in remission with maintenance therapy with azathioprine.

Plasmodium knowlesi: the emerging zoonotic malaria parasite

Antinori S, Galimberti L, Milazzo L, Corbellino M

Acta Trop, 2013 Feb;125(2):191-201.
PMID: 23088834 DOI: 10.1016/j.actatropica.2012.10.008

Plasmodium knowlesi was initially identified in the 30s as a natural Plasmodium of Macaca fascicularis monkey also capable of experimentally infecting humans. It gained a relative notoriety in the mid-30s as an alternative to Plasmodium vivax in the treatment of the general paralysis of the insane (neurosyphilis). In 1965 the first natural human infection was described in a US military surveyor coming back from the Pahang jungle of the Malaysian peninsula. P. knowlesi was again brought to the attention of the medical community when in 2004, Balbir Singh and his co-workers reported that about 58% of malaria cases observed in the Kapit district of the Malaysian Borneo were actually caused by P. knowlesi. In the following years several reports showed that P. knowlesi is much more widespread than initially thought with cases reported across Southeast Asia. This infection should also be considered in the differential diagnosis of any febrile travellers coming back from a recent travel to forested areas of Southeast Asia. P. knowlesi can cause severe malaria with a rate of 6-9% and with a case fatality rate of 3%. Respiratory distress, acute renal failure, shock and hyperbilirubinemia are the most frequently observed complications of severe P. knowlesi malaria. Chloroquine is considered the treatment of choice of uncomplicated malaria caused by P. knowlesi.

Antithrombocytopenic activity of carpaine and alkaloidal extract of Carica papaya Linn. leaves in busulfan induced thrombocytopenic Wistar rats

Zunjar V, Dash RP, Jivrajani M, Trivedi B, Nivsarkar M

J Ethnopharmacol, 2016 Apr 02;181:20-5.
PMID: 26812680 DOI: 10.1016/j.jep.2016.01.035

ETHNOPHARMACOLOGICAL RELAVANCE: The decoction of Carica papaya Linn. leaves is used in folklore medicine in certain parts of Malaysia and Indonesia for the treatment of different types of thrombocytopenia associated with diseases and drugs. There are several scientific studies carried out on humans and animal models to confirm the efficacy of decoction of papaya leave for the treatment of disease induced and drug induced thrombocytopenia, however very little is known about the bio-active compounds responsible for the observed activity. The aim of present study was to identify the active phytochemical component of Carica papaya Linn. leaves decoction responsible for anti-thrombocytopenic activity in busulfan-induced thrombocytopenic rats.
MATERIALS AND METHODS: Antithrombocytopenic activity was assessed on busulfan induced thrombocytopenic Wistar rats. The antithrombocytopenic activity of different bio-guided fractions was evaluated by monitoring blood platelet count. Bioactive compound carpaine was isolated and purified by chromatographic methods and confirmed by spectroscopic methods (LC-MS and 1D/2D-1H/13C NMR) and the structure was confirmed by single crystal X-ray diffraction. Quantification of carpaine was carried out by LC-MS/MS equipped with XTerra(®) MS C18 column and ESI-MS detector using 90:10 CH3CN:CH3COONH4 (6mM) under isocratic conditions and detected with multiple reaction monitoring (MRM) in positive ion mode.
RESULTS: Two different phytochemical groups were isolated from decoction of Carica papaya leaves: phenolics, and alkaloids. Out of these, only alkaloid fraction showed good biological activity. Carpaine was isolated from the alkaloid fraction and exhibited potent activity in sustaining platelet counts upto 555.50±85.17×10(9)/L with no acute toxicity.
CONCLUSIONS: This study scientifically validates the popular usage of decoction of Carica papaya leaves and it also proves that alkaloids particularly carpaine present in the leaves to be responsible for the antithrombocytopenic activity.

Fulltext Risk profiles of referred chronic kidney disease patients in a tertiary nephrology centre

Lim CT, R R, A S MZ

Pak J Med Sci, 2016 Mar-Apr;32(1):27-30.
PMID: 27022339 DOI: 10.12669/pjms.321.8214

OBJECTIVES: The aims of this study were to determine the seroprevalence of acute dengue in Universiti Kebangsaan Malaysia (UKM) Medical Centre and its correlation with selected haematological and biochemical parameters.
METHODS: This cross-sectional study was conducted from January to June 2015. A patient was serologically diagnosed with acute dengue if the dengue virus IgG, IgM or NS-1 antigen was reactive.
RESULTS: Out of 1,774 patients suspected to have acute dengue, 1,153 were serologically diagnosed with the infection, resulting in a seroprevalence of 64.9%. Dengue-positive patients had a lower mean platelet count (89 × 10(9)/L) compared to the dengue-negative patients (171 × 10(9)/L) (p<0.0001). The mean total white cell count was also lower in the dengue-positive cases (4.7 × 10(9)/L vs. 7.2 × 10(9)/L; p<0.0001). The mean haematocrit was higher in patients with acute dengue (42.5% vs. 40.0%; p<0.0001). Likewise, the serum alanine transaminase level was also higher in patients with acute dengue (108 U/L vs. 54 U/L; p<0.0001).
CONCLUSIONS: Dengue is very prevalent in UKM Medical Centre as most patients suspected to have acute dengue had serological evidence of the infection. The platelet count was the single most likely parameter to be abnormal (i.e. low) in patients with acute dengue.

A four-point clinical criteria distinguishes immune thrombocytopenia from acute lymphoblastic leukaemia

Lum SH, How SJ, Ariffin H, Krishnan S

Med J Malaysia, 2016 02;71(1):28-9.
PMID: 27130741

Immune thrombocytopenia is the most common diagnosis of isolated thrombocytopenia. The dilemma encountered by paediatricians is missing diagnosis of acute leukaemia in children with isolated thrombocytopenia. We demonstrated childhood ITP could be diagnosed using a four point clinical criteria without missing a diagnosis of acute leukaemia. Hence, bone marrow examination is not necessary in children with typical features compatible with ITP prior to steroid therapy. This can encourage paediatricians to choose steroid therapy, which is cheaper and non-blood product, as first line platelet elevating therapy in children with significant haemorrhage.

Disseminated histoplasmosis mimicking an acute appendicitis

Marsilla MM, Khairunisa AA, Azyani Y, Petrick P

Malays J Pathol, 2019 Aug;41(2):223-227.
PMID: 31427560

INTRODUCTION: Histoplasmosis can present in a myriad of clinical manifestations, which often makes its diagnosis difficult and occasionally, deceptive.
CASE REPORT: We describe a case of a 33 years old gentleman who was clinically diagnosed as acute appendicitis at initial presentation in view of a one-week history of fever, right lower quadrant abdominal pain- and guarding at right iliac fossa. He had thrombocytopenia and lymphopenia on presentation. Mesenteric lymphadenitis and small bowel lesion were found intraoperatively, which was respectively biopsied and resected. Histopathological result confirms disseminated histoplasmosis. Retroviral screen was positive. He was treated with amphotericin B for one week, subsequently switched to oral itraconazole, followed by initiation of highly active antiretroviral therapy (HAART).
DISCUSSION: This case illustrates the various nature of histoplasmosis presentation. A high index of suspicion is needed to clinch the diagnosis and subsequently institute prompt treatment as disseminated disease can be fatal if left untreated in an immunosuppressed host.

Fulltext Improving the percentage of platelet concentrates that meet platelet count standard

Norsuzilawati Abdullah, Noor Hamizah Mohd Hassan, Mohd Muhaimin Kambali

Q Bulletin, 2019;1(28):18-25.
MyJurnal

The platelet concentrates (PCs) is used for the treatment and prevention of bleeding in patients with reduced platelet number or function. The prepared platelet concentrates (PCs) must meet the specified quality control (QC) test standards. PCs that do not meet QC standards will reduce the efficacy of patient care and increase the need of repeated PC transfusion. According to the standards, at least 75% PCs tested should contain more than 60 x 109 per platelet count units. Hence, the objective of this study was to increase the percentage of PCs that meet the platelet count standard to more or equal to 75%.
A cross sectional study was conducted from May 2015 to March 2016. Data were collected and analysed through monthly PCs QC test results. A retrospective QC data review in March and April 2015 showed only 30% PCs achieved the platelet count standard for QC tests. Intervention package was implemented to tackle the identified risk factors that lead to platelet count problems that do not meet the standards.
The post remedial results showed an increase to 90% of PCs that meet platelet count standards in January to February 2016. The study also found that the rate of platelet count increment in patients after PCs transfusion increased from 5 x 109 per ml to 9 x 109 per ml after the study. Additionally, the repeated PC transfusion rate decreased from 22% to 18%. Achievements were successfully maintained after the study which was 89% in March to April 2017. Continuous monitoring need to be carried out to ensure the achievement remains in compliance with the established standards. This quality improvement method has facilitated successful platelet transfusion to patient by improving the quality and performance of PCs. The improvement strategies of this study have the potential to be implemented at other blood collection centers in order to improve the quality of healthcare services.

Fulltext An uncommon cause of leg swelling after exercise: a case report on an unprovoked deep vein thrombosis in young healthy man

Rathika Rajah, Alvin Oliver Payus, Norlaila Mustafa

Malaysian Journal of Medicine and Health Sciences, 2020;16(1):351-353.
MyJurnal

Antiphospholipid syndrome is a hypercoagulable autoimmune condition that predominantly affect the female and commonly manifest as arterio-venous thrombosis and recurrent miscarriage. Here, we present a unique case of a healthy young man who developed sudden onset of right leg swelling after exercise which was then found to be due to deep vein thrombosis via Doppler ultrasound. His blood investigations showed thrombocytopenia and prolonged coagulation profile. Therefore, antiphospholipid syndrome was suspected and later confirmed by positive autoim- mune antibodies. He was treated with long term moderate intensity oral warfarin. The objective of this case report is to share the uncommon occurrence of an unprovoked deep vein thrombosis secondary to antiphospholipid syn- drome in a healthy young man so that the possibility of deep vein thrombosis should be suspected in selected cases of non-resolving leg swelling after exercise as it can lead to fatal pulmonary embolism.

Fulltext Shrinking lung syndrome – a rare cause of recurrent dyspnoea in SLE

Baharuddin H, Mohd Zim MA, Rosman A, Mohd Zain M

Journal of Clinical and Health Sciences, 2017;2(1):35-38.

Here we present a 24-year-old lady with systemic lupus erythematosus (SLE) whom we diagnosed with shrinking lung syndrome (SLS), a rare manifestation of SLE. The initial SLE manifestation was alopecia, thrombocytopenia, serositis and vasculitis. Anti-nuclear antibody (ANA), anti-double stranded DNA (dsDNA) antibody, anti-ribonucleic (RNP) and anti-Ro antibody were positive. A year after diagnosis, she started to develop intermittent dyspnea and was hospitalised on three occasions. Lung examinations revealed reduced breath sounds at both bases and dullness at the right base. Multiple chest radiographs showed bilateral raised hemi-diaphragms. Other investigations including CT pulmonary angiogram, high resolution CT of the thorax, ventilation-perfusion scan and echocardiogram were not significant. On the third hospital admission, we noticed bilateral small lung volumes in the previous high resolution CT scan. Inspiratory and expiratory chest radiographs were performed and showed minimal change in lung volumes and a diagnosis of shrinking lung syndrome (SLS) was made. Her SLE remained active with lupus nephritis despite multiple immunosuppression and she passed away two years later due to sepsis with multi-organ failure.

Fulltext Spontaneous spinal subarachnoid haemorrhage: a rare complication of dengue fever

Nur Hidayati Mohd Sharif, Nor Arisah Misnan, Norashikin Saidon, Phaik Yee Ooi, Hilwati Hashim

Journal of Clinical and Health Sciences, 2017;2:54-57.

A 37-year-old woman presented with a short history of fever and bilateral lower limb
weakness. She also had impaired sensory function up to T4 spine level and lax anal tone.
Laboratory investigations confirmed dengue infection with mild thrombocytopenia. MRI of the
spine showed a spinal subarachnoid haemorrhage from the level of T4 till T9. Despite
medical and surgical interventions, her lower limb weakness persists. A high index of
suspicion is needed to recognise dengue-related neurological complications. This diagnosis
should be considered in any patients from dengue endemic areas presenting with acute
febrile illness with atypical neurological manifestations.
