Abstract Background Dengue virus infection (DVI) is a major health problem in many parts of the world. Its manifestations range from asymptomatic infections to severe disease. Although cardiac involvement has been reported in DVI, its incidence has not yet been well established. Methods From July 2016 to January 2018, patients hospitalized at the Hospital for Tropical Diseases, Faculty of Tropical Medicine, Mahidol University, Thailand, with dengue virus infection confirmed by positive NS1 or positive dengue immunoglobulin M findings, participated in the study. We characterized the incidence and change in cardiac function by serial echocardiography and levels of troponin-T and creatine kinase-myocardial band (CK-MB) on the day of admission, the day of defervescence, the first day of hypotension (if any), and at 2 week follow-up. Results Of the 81 patients evaluated, 6 (7.41%) exhibited elevated biomarker levels. There was no difference in clinical presentation amongst dengue fever, dengue haemorrhagic fever (DHF) and dengue shock syndrome (DSS), except for the amount of bleeding. Cardiac involvement was found in 22.2% of patients: 3 (3.70%) had left ventricular systolic dysfunction, 3 (3.70%) had transient diastolic dysfunction, 6 (7.41%) had increased levels of at least one cardiac biomarker (troponin-T or CK-MB), and 6 (7.41%) had small pericardial effusion. Myocarditis was suspected in only two patients (with DHF); thus, myocarditis was uncommon in patients with dengue virus infection. Three patients developed DSS during admission and were transferred to the intensive care unit. Conclusion Cardiac involvement in adults with dengue infection was common, ranging from elevated cardiac biomarker to myocarditis. Abnormalities in cardiac function had resolved spontaneously by the day of follow-up, without specific treatment. We found that DHF was a significant risk factor for cardiac involvement. Echocardiography is the investigation of choice for evaluating the haemodynamic status of patients with DVI, especially in severe dengue.

Réunion Island

Since 2018, a dengue epidemic has been ongoing in the French overseas department of Reunion Island, in the Indian Ocean, with more than 25,000 serologically confirmed cases. Currently, three dengue serotypes have been identified in Réunion Island (DENV-1, DENV-2, and DENV-3) progressing in the form of epidemic outbreaks. This arbovirus is mainly transmitted by mosquitoes of the genus Aedes and may be responsible for serious clinical forms. To date, very few cases of kidney transplant–related dengue virus infection have been described. Here we report the first case of severe dengue virus infection related to kidney transplantation from a patient previously infected with dengue. Testing for dengue fever with PCR search in donor’s urine may help complete the pretransplant assessment in areas where this disease occurs.

AbstractThe pathogenesis of dengue virus infection is attributed to complex interplay between virus, host genes and host immune response. Host factors such as antibody-dependent enhancement (ADE), memory cross-reactive T cells, anti-DENV NS1 antibodies, autoimmunity as well as genetic factors are major determinants of disease susceptibility. NS1 protein and anti-DENV NS1 antibodies were believed to be responsible for pathogenesis of severe dengue. The cytokine response of cross-reactive CD4+ T cells might be altered by the sequential infection with different DENV serotypes, leading to further elevation of pro-inflammatory cytokines contributing a detrimental immune response. Fcγ receptor-mediated antibody-dependent enhancement (ADE) results in release of cytokines from immune cells leading to vascular endothelial cell dysfunction and increased vascular permeability. Genomic variation of dengue virus and subgenomic flavivirus RNA (sfRNA) suppressing host immune response are viral determinants of disease severity. Dengue infection can lead to the generation of autoantibodies against DENV NS1antigen, DENV prM, and E proteins, which can cross-react with several self-antigens such as plasminogen, integrin, and platelet cells. Apart from viral factors, several host genetic factors and gene polymorphisms also have a role to play in pathogenesis of DENV infection. This review article highlights the various factors responsible for the pathogenesis of dengue and also highlights the recent advances in the field related to biomarkers which can be used in future for predicting severe disease outcome.

Dengue Virus Infection

Abstract Background Dengue fever is the most prevalent arbovirus among humans, its incidence has increased since the re-emergence, and Colombia is a hyperendemic country for this infection. The number of solid-organ transplant (SOT) recipients, at risk of acquiring dengue virus infection, is constantly increasing, and there are few data regarding the clinical course and outcomes of dengue infection among this population. The aim of this study was to describe dengue virus infection in SOT recipients in Cali, Colombia. Methods We present a case series of SOT recipients with dengue virus infection, diagnosed by World Health Organization criteria and a positive NS1 and/or IgM dengue antibodies, which were attended at the FVL from 2001 to 2018. Furthermore, we performed a literature review regarding dengue infection in SOT recipients. Results A total of 20 patients were included: 17 kidney and 3 liver recipients. The median age was 50.5 years (IQR = 31–63.5), 65% were female. The median time from transplant to dengue was 27.6 months (IQR = 3.82–59.12), and 3 patients had the infection in the first month after the transplant. The most common symptoms were fever (95%), myalgia, headache, and abdominal pain. Warning signs were present in 75% of patients, thrombocytopenia and hemorrhagic manifestations were present in 30% and 15%, respectively. 35% of patients were classified as severe dengue, and 45% were managed at the intensive care unit. Regarding laboratory findings, six patients had transaminases elevation more than three times the upper limit and 7 had serum creatinine elevation, which returned to normal levels. All patients were discharged and none of them had alterations in the graft function. To date, there are approximately 180 reported cases of dengue in SOT recipients (Table 2). Conclusion Dengue represents a threat among SOT recipients. Unlike other reports, all patients in this series had a full recovery after the infection, suggesting that timely and effective management of patients and the access to high complexity services could prevent fatal cases.

Background: Dengue viruses are flavivirus, which include four serotypes 1, 2, 3 and 4. Clinical expression of dengue virus infection vary from asymptomatic infection to severe dengue with shock. It is the most rapidly spreading vector borne disease in the world. An estimated 50 million dengue infections occur annually and approximately 2.5 billion people live in dengue endemic countries. The objective of this study was to predict the severity of Dengue illness by correlating the serum albumin levels.Methods: An observational cross-sectional study done on patients admitted in Basaveshwara Medical College and Research Institute, Chitradurga, Karnataka, a tertiary care Hospital. Patients with Dengue NS1 Ag or IgM positive are included in the study after meeting inclusion and exclusion criteria. Complete Blood count, serum albumin levels are estimated at the time of admission.Results: Study enrolled 100 patients with confirmed Dengue virus infection who were admitted to the hospital between July 2017 and December 2018. Serum samples taken within 24 hours of admission was used for biochemical tests. Out of 100 patients, 24 developed Severe Dengue. Cases of Severe Dengue had low levels of serum albumin. Multivariate analysis showed that early alterations of albumin i.e. out of 24 patients who developed severe dengue, 21 patients i.e. 92.7% had low albumin of <3gm/dlConclusions: Early changes in biochemical parameter, serum albumin can predict Severe Dengue in patients with Dengue febrile illness.

Dengue Virus Infection

Dengue Virus Infections are distributed in tropical and sub-tropical regions and transmitted by the mosquitoes such as Aedes aegypti and Aedes albopictus. Dengue virus can cause dengue fever, dengue hemorrhagic fever and dengue shock syndrome or dengue and severe dengue classified by World Health Organization. Beside it concurrent infection virus salmonella had been found some cases who showed fever more than 7 days. Concurrent infection with two agents can result in an illness having overlapping symptoms creating a diagnostic dilemma for treating physician, such as dengue fever with typhoid fever. The aim of this research is detection of dengue virus and secondary infection with Salmonella typhi in patients suspected dengue virus infection. Detection of dengue virus and Salmonella typhi using immunochromatography test such as NS1, IgG/IgM for dengue virus infection, and IgM/IgG Salmonella and blood culture. The fifty children with dengue virus infection came to Soerya hospital and 17 cases suspected dengue virus infection, five cases showed a positive NS1 on the second day of fever and one case concurrent with clinical manifestation of convulsi on the third days of fever there were five cases only showed positive. It was showed in this study that on the fourth to six day of fever in dengue virus infection accompanied by antibody IgM & IgG dengue. There were 12 cases showed the clinical manifestation of concurrent dengue viral infection and Salmonella, all of them showed a mild clinical manifestation and did not show plasma leakage and shock. In this study we found the length of stay of concurrent Dengue Virus Infection and Salmonella infection is more than 10 days. These patients were also more likely to have co-existing haemodynamic disturbances and bacterial septicaemia which would have required treatment with inotropes and antibiotics. This idea is very important to make update dengue viral management to decrease mortality in outbreak try to gain new prevention method before the occurrence of outbreak.
