PMID: 25692521 DOI: 10.1097/MBC.0000000000000280

The present study aimed to assess the cost-utility analysis of using an adjunctive recombinant activated factor VIIa (rFVIIa) in children for controlling life-threatening bleeding in dengue haemorrhagic fever (DHF)/dengue shock syndrome (DSS). We constructed a decision-tree model, comparing a standard care and the use of an additional adjuvant rFVIIa for controlling life-threatening bleeding in children with DHF/DSS. Cost and utility benefit were estimated from the societal perspective. The outcome measure was cost per quality-adjusted life years (QALYs). Overall, treatment with adjuvant rFVIIa gained QALYs, but the total cost was higher. The incremental cost-utility ratio for the introduction of adjuvant rFVIIa was $4241.27 per additional QALY. Sensitivity analyses showed the utility value assigned for calculation of QALY was the most sensitive parameter. We concluded that despite high cost, there is a role for rFVIIa in the treatment of life-threatening bleeding in patients with DHF/DSS.

Ng CY, Lee SL, Foo SL

Med J Malaysia, 2017 08;72(4):244-245.

PMID: 28889137 MyJurnal

Abdominal pain is one of the common presentations in severe dengue infection. We report a rare case of perforated gastric ulcer in a young man diagnosed with severe dengue infection and the challenges we faced in managing this patient. Perforated gastric ulcer need to be considered if there are signs of peritonitis and persistent abdominal pain that does not conform to the natural history of dengue. Proper imaging and early surgical intervention in perforated gastric ulcer is vital in preventing further complication and reducing the risk of mortality.

BACKGROUND: Sri Lanka experienced its largest dengue outbreak in 2017 with more than 185,000 dengue cases including at least 250 fatalities.

OBJECTIVES: Our study aimed to characterize the clinical, immunological and virological features of confirmed dengue patients in Sri Lanka during the outbreak in 2017 when unusual manifestations of severe dengue were observed.

STUDY DESIGN: Sera from 295 patients who were admitted to Teaching Hospital Kandy, Kandy, Sri Lanka between March 2017- January 2018 were subjected to NS1 antigen, IgM and IgG ELISAs, virus isolation, conventional and real time RT-PCR and next generation sequencing.

RESULTS: Primary and secondary infections were detected in 48.5 % and 51.5 % of the study population, respectively. Two hundred twenty five DENV strains were isolated (219 DENV-2, one DENV-3, two DENV-4, two mixed infections of DENV-2 and -3 and one mixed infection of DENV-2 and -4). Unusual and severe manifestations such as encephalitis, encephalopathy, liver failure, kidney failure, myocarditis, Guillain-Barré syndrome and multi-organ failure were noted in 44 dengue patients with 11 deaths. The viraemia levels in patients with primary infection and unusual manifestations were significantly higher compared to those in patients with secondary infection. A new clade of DENV-2 Cosmopolitan genotype strains was observed with the strains closely related to those from China, Malaysia, Indonesia, Singapore and Taiwan.

CONCLUSIONS: The new clade of DENV-2 cosmopolitan genotype observed in Sri Lanka in 2017 caused an unprecedented, severe dengue outbreak. The emergence of DENV-3 and DENV-4 in the 2017 outbreak might cause future outbreaks in Sri Lanka.

PMID: 19803300

This is a retrospective study of the gastrointestinal symptoms, signs and laboratory parameters in adult dengue patients admitted to Kuala Lumpur Hospital from 1st December 2004 to 31st December 2004. Clinical and laboratory parameters that may predict the need for intensive care were investigated. Six hundred sixty-six patients with clinical and biochemical features consistent with dengue infection were identified. Patients were stratified into those who required intensive care and those who were managed in non high dependency wards. Serum alanine aminotransaminase (ALT) levels were normal in 22.8% of patients and 5.9% of patients had acute fulminant hepatitis. More patients with dengue haemorrhagic fever (DHF) had elevated ALT levels as compared to patients with classic dengue fever (DF) (p = 0.012). Patients with DF had a statistically significant lower mean ALT level as compared to patients with DHF. Abdominal pain (p = 0.01) and tenderness (p<0.001), gastrointestinal bleed (p<0.001), jaundice (p<0.001), hepatomegaly (p<0.001) and ascites (p<0.001) were predictors of need for intensive care. We conclude that gastrointestinal manifestations are very common in dengue patients. Presence of abdominal pain and tenderness, gastrointestinal bleed, jaundice, hepatomegaly and ascites can be used to triage patients requiring intensive care.

Shaiful Ehsan SM, Iskandar FO, Mohd Ashraf AR

Med J Malaysia, 2019 08;74(4):347-348.

PMID: 31424049

Varicella zoster infection is one of the self-limiting viral infections during childhood and dengue fever is an endemic infection in Malaysia, which commonly occurs in the form of nonspecific febrile illness at the initial stage. It is rare for the two viral infections to occur simultaneously. A case of dengue fever without warning sign in a five-year old girl was reported, with early symptoms of fever and vesicular rashes. She was clinically diagnosed with varicella zoster infection during the first visit. Surprisingly, she remained febrile even on day six of illness despite no new vesicular lesions on her skin. Due to suspicion of another infection, follow-up investigation was done and revealed isolated thrombocytopenia. This finding was confirmed with positive NS1Ag. A case of rare dengue fever concomitant with varicella zoster infection was reported.

Dengue associated haemophagocytic lymphohystiocytosis: An often-missed complication of a common infection

Takkinsatian P, Sowithayasakul P, Prommalikit O

Med J Malaysia, 2020 09;75(5):588-590.

PMID: 32918433

Hemophagocytic lymphohistiocytosis (HLH) is a severe and life-threatening condition causing multisystem involvement such as cytopenia, hepatosplenomegaly, and death. Dengue infection is one of the leading causes of HLH. We reviewed three cases of children at HRH Princess Maha Chakri Sirindhorn Medical Center, Faculty of Medicine, Srinakharinwirot University, Nakhon Nayok, Thailand, with dengue fever who subsequently developed HLH, based on the HLH-2004 diagnostic criteria. Following treatment with dexamethasone and intravenous immunoglobulin, there was a dramatic response including defervescence and improvement of cytopenia, hyperfibrinogenemia, and hyperferritinemia. Key features for diagnosis of dengue fever complicated by HLH include a history of prolonged fever exceeding seven days, splenomegaly, and worsening cytopenia. Early recognition and treatment are crucial for a successful outcome.

PMID: 23453417 DOI: 10.1016/j.bjid.2012.09.007

OBJECTIVE: To describe the clinical manifestations and outcome of acute liver failure (ALF) associated with dengue viral infection, a rare but severe complication.
METHODS: One hundred and fifty five consecutive patients with ALF admitted to the national liver centre from 2001 to 2009 were reviewed retrospectively. Eight cases due to dengue infection were identified and their clinical characteristics are described.
RESULTS: All patients had severe dengue with one dengue shock syndrome. The median (minimum, maximum) age was 33.5 (17, 47) years with 50% female. The median (minimum, maximum) duration from the onset of fever to development of ALF was 7.5 (5, 13) days and the maximum hepatic encephalopathy (HE) grade were III in five patients and II in three patients. Three patients had systemic inflammatory responses (SIRS) on admission and were in grade III HE. The presence of SIRS on admission was associated with higher grade of HE and its development during the course of hospitalization was associated with worsening HE grade. The hepatitis was characterized by marked elevations in: alanine transaminase [median admission 1140.5 u/L (639, 4161); median peak 2487 u/L (998, 5181)], serum bilirubin [median admission 29 μmol/L (23, 291); median peak 127 μmol/L (72, 592)], and prothrombin time [median admission 16.8s (15.3, 26.2); median peak 22s (15.3, 40.7)]. The survival rate with standard medical therapy alone was 100%.
CONCLUSIONS: Dengue associated ALF manifest about one week after the onset of fever with severe hepatitis and encephalopathy. In our experience, the outcome with standard medical therapy alone is excellent.

Thrombotic Thrombocytopenic Purpura in Dengue Fever

Tee TY, Cader RA

Acta Med Indones, 2021 Apr;53(2):208-212.

PMID: 34251350

Thrombotic thrombocytopenic purpura is a rare but life threatening medical condition. Early recognition and treatment of thrombotic thrombocytopenic purpura is important especially in patients who do not present with the classic pentad to reduce the high mortality. Herein, we describe a case of a patient who does not fulfil the classic pentad features thrombotic thrombocytopenic purpura that was induced by dengue fever. The patients' initial full blood picture did not have all the typical features of microangiopathic haemolytic anaemia but there were fragmented red blood cells. However, even a small number of fragmented red blood cells in the peripheral blood should alert physicians of the possible diagnosis of thrombotic thrombocytopenic purpura together with other symptoms. Furthermore, signs and symptoms of thrombotic thrombocytopenic purpura and dengue fever can overlap such as fever, thrombocytopenia, neurological deficit mimicking dengue encephalopathy and dengue induced acute kidney injury.

Eyelid reconstruction is complex and challenging since it is not only for structural and functional restoration, but also for an acceptable aesthetic result. In full thickness eyelid injuries, it will involve both anterior and posterior lamella. Therefore, when reconstructing the defect, it requires at least two layers; one will be a flap with blood supply, and the other can be a free graft. In this case, a rotational advancement cheek flap and composite graft were used to reconstruct the lower eyelid.

Fulltext Effect of Blastocystis sp. in dengue patients-Increase in the treatment cost and exacerbation of symptoms

Thergarajan G, Kumar S, Bhassu S, Omar SFBS, Rampal S

PMID: 30893309 DOI: 10.1371/journal.pone.0211034

Increasing incidences of dengue have become a global health threat with major clinical manifestation including high fever and gastrointestinal symptoms. These symptoms were also expressed among Blastocystis sp. infected individuals, a parasite commonly seen in human stools. This parasite has been previously reported to replicate faster upon exposure to high temperature. The present study is a hospitalized-based cross-sectional study involved the collection of faecal sample from dengue patients. Stool examination was done by in vitro cultivation to isolate Blastocystis sp. Growth pattern of all the positive isolates were analyzed to identify the multiplication rate of Blastocystis sp. isolated from dengue patients. Distribution of Blastocystis sp. among dengue patients was 23.6%. Dengue patients who were positive for Blastocystis sp. infection denoted a significantly higher fever rate reaching 38.73°C (p<0.05) compared to the non-Blastocystis sp. infected patients (38.44°C). It was also found that Blastocystis sp. infected patients complained of frequenting the toilet more than five times a day (p<0.05) compared to those who were non-Blastocystis sp. infected. At the same time, the duration of hospitalization was significantly longer (p<0.05) for Blastocystis sp. infected dengue patients compared to the non-Blastocystis sp. infected patients. Besides, Blastocystis sp. isolated from dengue patients (in vivo thermal stress) showed a higher growth rate compared to the non-dengue isolated which was exposed to high temperature (in vitro thermal stress). Our findings suggest that presence of Blastocystis sp. during dengue infection could trigger the increase of temperature which could be due to highly elevated pro inflammatory cytokines by both parasitic and virus infection. This could justify why the temperature in Blastocystis sp. infected dengue patients is higher compared to the non-Blastocystis sp. infected patients. Higher temperature could have triggered a greater parasite multiplication rate that contributed to the aggravation of the gastrointestinal symptoms.

Acute disseminated encephalomyelitis complicating dengue infection with neuroimaging mimicking multiple sclerosis: A report of two cases

Viswanathan S, Botross N, Rusli BN, Riad A

Mult Scler Relat Disord, 2016 Nov;10:112-115.

PMID: 27919476 DOI: 10.1016/j.msard.2016.10.001

Acute disseminated encephalomyelitis (ADEM) complicating dengue infection is still exceedingly rare even in endemic countries such as Malaysia. Here we report two such cases, the first in an elderly female patient and the second in a young man. Both presented with encephalopathy, brainstem involvement and worsening upper and lower limb weakness. Initial magnetic resonance imaging (MRI) of the brain was normal in the first case. Serum for dengue Ig M and NS-1 was positive in both cases. Cerebrospinal fluid (CSF) showed pleocytosis in both with Dengue IgM and NS-1 positive in the second case but not done in the first. MRI brain showed changes of perpendicular subcortical palisading white matter, callosal and brainstem disease mimicking multiple sclerosis (MS) in both patients though in the former case there was a lag between the onset of clinical symptoms and MRI changes which was only clarified on reimaging. The temporal evolution and duration of the clinical symptoms, CSF changes and neuroimaging were more suggestive of Dengue ADEM rather than an encephalitis though initially the first case began as dengue encephalitis. Furthermore in dengue encephalitis neuroimaging is usually normal or rarely edema, haemorrhage, brainstem, thalamic or focal lesions are seen. Therefore, early recognition of ADEM as a sequelae of dengue infection with neuroimaging mimicking MS and repeat imaging helped in identifying these two cases. Treatment with intravenous steroids followed by maintenance oral steroids produced good outcome in both patients.

PMID: 26209387 DOI: 10.1016/j.jcv.2015.06.004

Infection associated hemophagocytic syndrome is increasingly recognized as a potentially fatal complication of dengue fever. It should be suspected with prolonged fever beyond seven days associated with hepatosplenomegaly, hyperferritinemia, worsening cytopenias and development of multiorgan dysfunction. Surge of similar pro-inflammatory cytokines observed in dengue associated hemophagocytic syndrome and multiorgan dysfunction may indicate they are part of related inflammatory spectrum. A proportion of patients recovered with supportive therapy, however most required interventions with corticosteroids, intravenous immunoglobulin or chemotherapy. We report three cases of dengue associated IAHS with good outcome following early recognition and treatment with dexamethasone and intravenous immunoglobulin.
