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.

PMID: 1803975

Virus associated haemophagocytic syndrome (VAHS), a distinct clinico-pathologic entity, is characterised by systemic proliferation of non-neoplastic histotiocytes showing haemophagocytosis resulting in blood cytopaenia. It has been described in relation to several viruses earlier. Here we describe a young girl who developed this reactive process during the course of dengue haemorrhagic fever (DHF).

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.

Eight cases of liver failure and encephalopathy were observed among twenty cases of grade 3 and grade 4 dengue hemorrhagic fever/dengue shock syndrome admitted to the Department of Pediatrics, University Hospital, Kuala Lumpur from January 1990 to December 1991. All patients with deterioriation in mental status showed a marked increase in liver enzymes (aspartate and alanine aminotransaminases) and severe coagulopathy. Six patients needed cerebral protection, including ventilation, intravenous sedation and muscle relaxants. There was one death during the period of study and one case of residual hemiparesis in a boy who had, in addition, intracerebral hemorrhage. All other survivors had complete recovery of liver and neurological function.

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.

A previously well 13-year-old boy presented with a short history of fever and altered mental status. His mother was admitted for dengue fever and there had been a recent dengue outbreak in their neighbourhood. He was diagnosed with dengue encephalitis as both his dengue non-structural protein 1 (NS-1) antigen and cerebrospinal fluid (CSF) dengue polymerase chain reaction (PCR) were positive. He did not have haemoconcentration, thrombocytopenia or any warning signs associated with severe dengue. He recovered fully with supportive treatment. This case highlights the importance of considering the diagnosis of dengue encephalitis in patients from dengue endemic areas presenting with an acute febrile illness and neurological symptoms.

Fulltext Determinants of mortality and prolonged hospital stay among dengue patients attending tertiary care hospital: a cross-sectional retrospective analysis

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

BMJ Open, 2017 Jul 10;7(7):e016805.

PMID: 28698348 DOI: 10.1136/bmjopen-2017-016805

OBJECTIVES: Dengue imposes substantial economic, societal and personal burden in terms of hospital stay, morbidity and mortality. Early identification of dengue cases with high propensity of increased hospital stay and death could be of value in isolating patients in need of early interventions. The current study was aimed to determine the significant factors associated with dengue-related prolonged hospitalisation and death.

DESIGN: Cross-sectional retrospective study.

SETTING: Tertiary care teaching hospital.

PARTICIPANTS: Patients with confirmed dengue diagnosis were stratified into two categories on the basis of prolonged hospitalisation (≤3 days and >3 days) and mortality (fatal cases and non-fatal cases). Clinico-laboratory characteristics between these categories were compared by using appropriate statistical methods.

RESULTS: Of 667 patients enrolled, 328 (49.2%) had prolonged hospitalisation. The mean hospital stay was 4.88±2.74 days. Multivariate analysis showed that dengue haemorrhagic fever (OR 2.3), elevated alkaline phosphatase (ALP) (OR 2.3), prolonged prothrombin time (PT) (OR 1.7), activated partial thromboplastin time (aPTT) (OR 1.9) and multiple-organ dysfunctions (OR 2.1) were independently associated with prolonged hospitalisation. Overall case fatality rate was 1.1%. Factors associated with dengue mortality were age >40 years (p=0.004), secondary infection (p=0.040), comorbidities (p<0.05), acute kidney injury (p<0.001), prolonged PT (p=0.022), multiple-organ dysfunctions (p<0.001), haematocrit >20% (p=0.001), rhabdomyolosis (p<0.001) and respiratory failure (p=0.007). Approximately half of the fatal cases in our study had prolonged hospital stay of greater than three days.

CONCLUSIONS: The results underscore the high proportion of dengue patients with prolonged hospital stay. Early identification of factors relating to prolonged hospitalisation and death will have obvious advantages in terms of appropriate decisions about treatment and management in high dependency units.

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.

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.

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.

A 24 year-old Malay lady presented with high grade fever, myalgia, generalized rashes, severe headache and was positive for dengue serology test. Her lowest platelet count was 45 × 10(9) cells/L. She complained of sudden onset of painlessness, profound loss of vision bilaterally 7 days after the onset of fever. On examination, her right eye best corrected vision was 6/30 and left eye was 6/120. Her anterior segment examination was unremarkable. Funduscopy revealed there were multiple retinal haemorrhages found at posterior pole of both fundi and elevation at fovea area with subretinal fluid. Systemic examination revealed normal findings except for residual petechial rashes. She was managed conservatively. Her vision improved tremendously after 2 months. The retinal hemorrhages and foveal elevation showed sign of resolving. Ocular manifestations following dengue fever is rare. However, bilateral visual loss can occur if both fovea are involved.

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.

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.

A 44-year-old woman was admitted to our hospital with dengue fever. She developed a haematoma in the right arm at the site of a previous arterial line insertion. Due to coexisting thrombocytopenia, the bleeding was severe enough to cause compartment syndrome. An emergency fasciotomy was performed and her limb salvaged. The case illustrates one important potential complication of this common infectious disease.
