Fulltext The clinical features and outcomes of acute liver failure associated with dengue infection in adults: a case series

Tan SS, Bujang MA

Braz J Infect Dis, 2013 Mar-Apr;17(2):164-9.
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.

Cavity Forming Pneumonia Due to Staphylococcus aureus Following Dengue Fever

Miyata N, Yoshimura Y, Tachikawa N, Amano Y, Sakamoto Y, Kosuge Y

Am J Trop Med Hyg, 2015 Nov;93(5):1055-7.
PMID: 26304914 DOI: 10.4269/ajtmh.15-0045

While visiting Malaysia, a 22-year-old previously healthy Japanese man developed myalgia, headache, and fever, leading to a diagnosis of classical dengue fever. After improvement and returning to Japan after a five day hospitalization, he developed productive cough several days after defervescing from dengue. Computed tomography (CT) thorax scan showed multiple lung cavities. A sputum smear revealed leukocytes with phagocytized gram-positive cocci in clusters, and grew an isolate Staphylococcus aureus sensitive to semi-synthetic penicillin; he was treated successfully with ceftriaxone and cephalexin. This second reported case of pneumonia due to S. aureus occurring after dengue fever, was associated both with nosocomial exposure and might have been associated with dengue-associated immunosuppression. Clinicians should pay systematic attention to bacterial pneumonia following dengue fever to establish whether such a connection is causally associated.

Dengue-induced Acute Kidney Injury (DAKI): A Neglected and Fatal Complication of Dengue Viral Infection--A Systematic Review

Mallhi TH, Sarriff A, Adnan AS, Khan YH, Hamzah AA, Jummaat F, et al.

J Coll Physicians Surg Pak, 2015 Nov;25(11):828-34.
PMID: 26577971 DOI: 11.2015/JCPSP.828834

Dengue Viral Infection (DVI) imperils an estimated 2.5 billion people living in tropical and subtropical regions. World Health Organization (2011) guidelines also classified dengue as 'Expanded Dengue Syndrome' to incorporate wide spectrum of unusual manifestations of dengue infection affecting various organ systems - including liver, kidney, heart and brain. Renal involvements are least appreciated area of dengue infection, therefore, we systematically reviewed studies describing renal disorders in dengue infection, with emphasis on Acute Kidney Injury (AKI). The purpose of current review is to underscore clinicians’attention to this neglected intricacy of DVI. It suggests that dengue induced renal involvements vary from glomerulonephritis, nephrotic range proteinuria and AKI. We observed great disparity in incidence of AKI among dengue patients, based upon criteria used to define AKI. AKI among dengue patients was found to be associated with significant morbidity, mortality and longer hospitalization, adding financial burden to patients and healthcare system. Additionally, we identified several predictors of AKI in dengue patients including old age, obesity, severe dengue infection and concurrent bacterial or viral infection. Direct viral injury and deposition of antigen-antibody complex in glomerulus were found to be possible causes of renal disorders in dengue infection. Prior knowledge of clinico-laboratory characteristics and risk factors with early detection of AKI by using appropriate criteria would not only reduce morbidity and mortality but also decrease burden to patients and healthcare system.

Dengue fever complicated by pulmonary haemorrhage manifesting as haemoptysis

Liam CK, Yap BH, Lam SK

J Trop Med Hyg, 1993 Jun;96(3):197-200.
PMID: 8505777

A 17-year-old girl was admitted to hospital with dengue fever. On the ninth day of fever she developed haemoptysis and chest X-ray changes consistent with haemorrhage in her lungs. Thrombocytopaenia and mild coagulopathy were the most likely cause of this unusual haemoptysis in this patient. Investigations excluded other causes for the haemoptysis.

Fulltext Outpatient management of dengue infection in the University Hospital, Kuala Lumpur

Chin CK

PMID: 8277784

Dengue fever is endemic in Malaysia with frequent epidemics especially in urban areas. This infection can present in a wide range of severity, from a nonspecific febrile illness to life threatening dengue haemorrhagic fever and dengue shock syndrome. It is worth noting that dengue haemorrhagic fever comprised 11.2% of all reported cases in Malaysia in 1991.Patients tend to consult their primary care physicians early. It is the duty of the primary care physicians to make an accurate diagnosis and to detect the complications. However, there has not been any known reliable predictor for the occurrence of complications during the early stage of the illness. Hence, primary care physicians often face the problem of having to deal with this uncertainty. Referring all these patients to the hospitals for admission is obviously not practical but managing them at home may involve high risks. In order to assist primary care physicians, the Primary Care Unit in the University Hospital uses a set of guidelines for the outpatient management of the infection. These guidelines and their assessment will be discussed.

Dengue-associated adult respiratory distress syndrome

Lum LC, Thong MK, Cheah YK, Lam SK

Ann Trop Paediatr, 1995 Dec;15(4):335-9.
PMID: 8687212 DOI: 10.1080/02724936.1995.11747794

In dengue shock syndrome, an acute increase in capillary permeability results in leakage of plasma into the interstitial space. Pleural effusion is commonly seen in dengue shock syndrome. We report three cases of dengue-associated adult respiratory distress syndrome (ARDS) in children, in all of whom dengue haemorrhagic fever, presenting with grade 3 or grade 4 dengue shock syndrome with disseminated intravascular coagulopathy, was confirmed. The criteria for the diagnosis of ARDS were based on the expanded definition of ARDS by Murray et al. Treatment consisted of fluid resuscitation, correction of coagulopathy and mechanical ventilation. All three children had multi-organ impairment, but it was more severe in the two who died. The one survivor was well at discharge.

Adult dengue haemorrhagic fever at Kuala Lumpur Hospital: retrospective study of 102 cases

Ibrahim NM, Cheong I

Br J Clin Pract, 1995 Jul-Aug;49(4):189-91.
PMID: 7547159

A retrospective study involving 102 adults with dengue haemorrhagic fever (DHF) was conducted to investigate the demographic aspect, clinical presenting features, laboratory investigations, complications, and mortality associated with the disease. The clinical diagnosis of DHF was in accordance with WHO recommendations. Epistaxis, gingivitis, haematemesis and gastritis were among the common complications. Platelet levels tended to decline from a higher value on admission (mean 67,000/mm3) to lower levels on subsequent days, with the lowest (mean 61,000/mm3) being on day 6 of the fever. Hyponatraemia (46.8%) was commonly observed. Morbidity of DHF was significant (29.4%) but the case fatality rate remained low (2.0%) in our adults, suggesting that adults are less likely than children to suffer from shock syndrome.

Bleeding manifestations of dengue haemorrhagic fever in Malaysia

George R, Duraisamy G

Acta Trop, 1981 Mar;38(1):71-8.
PMID: 6111919

Analysis of the bleeding manifestations of 130 cases of dengue haemorrhagic fever admitted into the Children's ward of the General Hospital, Kuala Lumpur from May 1973 to September 1978 has been done. Petechial skin rash, epistaxis and gum bleeding were seen most commonly in mild and moderately severe cases. However, blood stained gastric aspirates, and severe haematemesis were seen in severe or very severe cases. Though with better vector control and preventive measures, a marked reduction in the incidence of the cases has been noted, severe cases were seen with symptoms of shock and gastrointestinal bleeding. These symptoms carried a bad prognosis. Among 15 children that died 10 had gastrointestinal bleeding and 2 had a disseminated intravascular coagulation defect. Lymphocytosis with atypical lymphocytes, low platelet count, low reticulocyte count and raised packed cell volume were the main haematological features seen in all these cases. All these features reverted to normal within a week. Mild evidence of disseminated intravascular coagulation was seen in a number of cases, but severe features were seen only in four. Two cases improved as a result of heparin therapy.

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.

Fulltext Severe Plasmodium knowlesi with dengue coinfection

Che Rahim MJ, Mohammad N, Besari AM, Wan Ghazali WS

BMJ Case Rep, 2017 Feb 20;2017.
PMID: 28219910 DOI: 10.1136/bcr-2016-218480

We report a case of severe Plasmodium knowlesi and dengue coinfection in a previously healthy 59-year-old Malay man who presented with worsening shortness of breath, high-grade fever with chills and rigors, dry cough, myalgia, arthralgia, chest discomfort and poor appetite of 1 week duration. There was a history mosquito fogging around his neighbourhood in his hometown. Further history revealed that he went to a forest in Jeli (northern part of Kelantan) 3 weeks prior to the event. Initially he was treated as severe dengue with plasma leakage complicated with type 1 respiratory failure as evidenced by positive serum NS1-antigen and thrombocytopenia. Blood for malarial parasite (BFMP) was sent for test as there was suspicion of malaria due to persistent thrombocytopenia despite recovering from dengue infection and the presence of a risk factor. The test revealed high count of malaria parasite. Confirmatory PCR identified the parasite to be Plasmodium knowlesi Intravenous artesunate was administered to the patient immediately after acquiring the BFMP result. Severe malaria was complicated with acute kidney injury and septicaemic shock. Fortunately the patient made full recovery and was discharged from the ward after 2 weeks of hospitalisation.

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.

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

PLoS One, 2019;14(3):e0211034.
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.

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.

Fulltext Incidence, Characteristics and Risk Factors of Acute Kidney Injury among Dengue Patients: A Retrospective Analysis

Mallhi TH, Khan AH, Adnan AS, Sarriff A, Khan YH, Jummaat F

PLoS One, 2015;10(9):e0138465.
PMID: 26421839 DOI: 10.1371/journal.pone.0138465

BACKGROUND: Dengue induced acute kidney injury (AKI) imposes heavy burden of illness in terms of morbidity and mortality. A retrospective study was conducted to investigate incidence, characteristics, risk factors and clinical outcomes of AKI among dengue patients.
METHODOLOGY: A total 667 dengue patients (2008-2013) were retrospectively evaluated and were stratified into AKI and non-AKI groups by using AKIN criteria. Two groups were compared by using appropriate statistical methods.
RESULTS: There were 95 patients (14.2%) who had AKI, with AKIN-I, AKIN-II and AKIN-III in 76.8%, 16.8% and 6.4% patients, respectively. Significant differences (P<0.05) in demographics and clinico-laboratory characteristics were observed between patients with and without AKI. Presence of dengue hemorrhagic fever [OR (95% CI): 8.0 (3.64–17.59), P<0.001],rhabdomyolysis [OR (95% CI): 7.9 (3.04–20.49)], multiple organ dysfunction OR (95% CI):17.9 (9.14–35.12), P<0.001], diabetes mellitus [OR (95% CI): 4.7 (1.12–19.86), P = 0.034], late hospitalization [OR (95% CI): 2.1 (1.12–19.86), P = 0.033] and use of nephrotoxic drugs [OR(95% CI): 2.9 (1.12–19.86), P = 0.006] were associated with AKI. Longer hospital stay (>3days) was also observed among AKI patients (OR = 1.3, P = 0.044) [corrected].Additionally, 48.4% AKI patients had renal insufficiencies at discharge that were signicantly associated with severe dengue, secondary infection and diabetes mellitus. Overall mortality was 1.2% and all fatal cases had AKI.
CONCLUSIONS: The incidence of AKI is high at 14.2% among dengue patients, and those with AKI portended significant morbidity, mortality, longer hospital stay and poor renal outcomes. Our findings suggest that AKI in dengue is likely to increase healthcare burden that underscores the need of clinicians' alertness to this highly morbid and potentially fatal complication for optimal prevention and management.

Fulltext Post-dengue parkinsonism

Azmin S, Sahathevan R, Suehazlyn Z, Law ZK, Rabani R, Nafisah WY, et al.

BMC Infect Dis, 2013;13:179.
PMID: 23594500 DOI: 10.1186/1471-2334-13-179

BACKGROUND: Dengue is a common illness in the tropics. Equally common are neurological complications that stem from dengue infection. However, to date, parkinsonism following dengue has not been reported in medical literature.
CASE PRESENTATION: A previously well 18-year old man developed parkinsonism, in addition to other neurological symptoms following serologically confirmed dengue fever. Alternative etiologies were excluded by way of imaging and blood investigations.
CONCLUSIONS: The authors detail the first reported case of parkinsonism complicating dengue fever. Keeping rare presentations of common illnesses in mind, it behoves clinicians to consider parkinsonism as a complication following dengue infection. This would prevent injudicious treatment with L-dopa and dopamine agonists. Immunosuppression with steroids has been shown to be helpful in certain cases.
