Abstract: Dengue is an arboviral disease that is widely spread across the world by Aedes mosquitoes. The early onset of dengue virus infection is difficult to identify due to indistinctive clinical symptoms. Therefore, simple laboratory test is required in the early diagnosis of dengue virus infection. Laboratory test that include routine blood test and blue plasma lymphocyte are important as rapid and relatively cheap diagnostic tool. Blue plasma lymphocytes derived from lymphoid which acts as an immune response that can be found in 4% of peripheral blood on 98% dengue hemorrhagic fever cases. Besides the increases in blue plasma lymphocytes, dengue virus infection can also causes leucopenia. Leucopenia in Dengue Hemorrhagic Fever (DHF) is characterized by the decrease of neutrophile count that happened during the early critical phase (third day of fever). This is a cross-sectional study using samples of 37 children who are infected with dengue virus in RS Advent Manado, RS TNI AD Wolter Monginsidi, RS Pancaran Kasih Manado during December 2014 to January 2015. Inclusion criteria are children below age 15, who have NS1 or IgG/IgM positive, who are on the third until seventh day of fever, whose parents or guardian have signed the informed consent. Conclusion: Leucopenia (leukocyte count below 4000/mm3) was found in children with dengue virus infection who had their routine blood test. Blue plasma lymphocytes are not always found in patients with NS1-AG, IgG/IgM positive.Keywords: dengue virus infection, leucocyte, blue plasma lymphocyteAbstrak: Dengue adalah penyakit arboviral yang paling banyak tersebar di dunia yang ditularkan nyamuk Aedes.

The Mean

Clinical manifestations of dengue virus infection vary from unspecified fever, dengue fever (DF) and dengue hemorrhagic fever (DHF). The fundamental difference in the diagnosis between DF and DHF is plasma leakage, hypotension, thrombocytopenia and hemorrhagic diathesis in DHF. The objectives of the study were to determine the lowest platelet, haematocrit increase, and TNF-α levels in DF and DHF patients as an indication of severity of dengue virus infection. The cross-sectional study was conducted by taking 54 blood samples of patients aged 26-45 years who were infected by dengue virus and grouped into two groups: DF patient group (27 blood samples) and DHF group (27 blood samples). The lowest platelets and hematocrit rise were determined by Hematology Analyzer and the TNF-α levels were determined by ELISA. The data obtained were statistically analyzed by independent Mann-Whitney test. The results showed that the lowest mean platelet counts of DF patients were significantly (p <0.01) higher than those of DHF patients. The mean hematocrit increase in DF patients was significantly (p <0.01) lower than that of the DHF patients and the mean TNF-α levels of DF patients were significantly (p <0.01) lower than the DHF patients. Based on the results of this study it can be concluded that the lowest platelets, hematocrit increase and TNF-α levels are an indication of the severity of dengue virus infection.

Dengue hemorrhagic fever (DHF) is an arboviral disease that is widespread worldwide. Dengue virus is transmitted to humans through the bite of an infected female Aedes mosquito. Infection of one of the viral serotypes in the majority of cases causes no symptoms or may cause clinical symptoms. Dengue virus infection causes the body to respond clinically and form antibodies. This research study is to provide clinical features and immune response in patients with Dengue hemorrhagic fever. This article uses an observational study design of secondary data of both IgM and IgG sequential examinations of 52 people with Dengue hemorrhagic fever infections at Lindi maria hospital in 2018.The results of the descriptive analysis showed that male population with Dengue hemorrhagic fever was 55.8%, and the highest rate of infection was in adolescents 34.6%. The most clinical features found were fever 91.4%; headache 24.0%; swallow pain 20.8%; vomiting 21.8%; and gastric pain18.7%. Serological examination showed 19.2% positive IgM; 36.5% IgG; and 44.2% positive both IgM and IgG. The Dengue virus infection in 52 patients in East Sumba is mostly secondary infection (80.8%) with the most infected age group is the adult group (≥ 16 years old).

Degree Of Severity

The clinical manifestation of dengue virus infection is often not clear, varies widely from mild to severe. Exposure of dengue virus which serotype is different from a previous infection is a risk factor for the severe manifestation of dengue virus infection. Dengue hemorrhagic fever is classified into four degrees of severity based on clinical manifestations and laboratory results. Real-time RT-PCR Dengue can detect dengue virus serotype in early dengue virus infection. The aimed of this study was to prove the correlation between dengue virus serotype and degree of severity in adult patients. This study was a cross-sectional observational design done in February until July 2016. Subjects consisted of 100 dengue virus infection patients. Serum of the patients was examined using Real-time RT-PCR Dengue (Simplexa™ Dengue). It was shown that from 46 patients with DENV-3 serotype was 63%, DENV-2 serotype 17.4%, DENV-1 serotypes 17.4% and mixed infection of DENV-1 and DENV-3 serotype 2.2%. There was not any DENV-4 serotype. Dengue Hemorrhagic Fever (DHF) stage I was 47.8%, DHF stage II was 30.4%, DHF stage III was 10.9% and Dengue Fever was 10.9%. There was not any DHF stage IV. There was not enough evidence that DENV-3 correlated with the degree of severity (p= 0.510). Based on this research, DENV-3 serotype was the dominant serotype prevalent at the Dr. Soetomo Hospital. There was no correlation between viral dengue serotype and severity in dengue adult patients in this study.

Abstract Background Dengue virus infection has been an important and serious public health concern in Taiwan, where local outbreaks of dengue fever occurred almost every year. To our knowledge, no nationwide investigation has been carried out to determine the actual extent of infection in the general population. Methods A total of 1308 random serum samples were collected from the general population in Taiwan in 2010. The antibody-captured enzyme-linked immunosorbent assays were used to detect DENV-specific IgM and IgG. Demographics data were used for risk analysis. Results The weighted overall seroprevalence was 1.96% for anti-DENV IgM, and 3.4% for anti-DENV IgG, respectively. A significant rise of DENV IgG seropositive rate had been noted since late adulthood stage, from 1.1% at the age group of 50–59 years to 7.6% at the age group of 60–69 years. For people aged over 70 years, the seropositive rate reached 19%. Age, nationality, and regions of residency were associated with the IgG seropositivity. There was no statistically significant difference in seroprevalence of anti-Dengue IgM, indicating recent infection, among univariate predictors we proposed, including gender, age, residency, nationality, and household size. Conclusions Our results indicated that the majority of population in Taiwan born after 1940 is naive to dengue virus and the prevalence of IgG antibody against dengue virus rises with age. Nationality, and regions of residency are associated with the exposure of population to infection by dengue viruses. Further studies are needed to realize the current situation of seroprevalence of dengue fever in Taiwan.

Primary Fluid

Dengue viruses cause two severe diseases that alter vascular fluid barrier functions, dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). The endothelium is the primary fluid barrier of the vasculature and ultimately the effects of dengue virus infection that cause capillary leakage impact endothelial cell (EC) barrier functions. The ability of dengue virus to infect the endothelium provides a direct means for dengue to alter capillary permeability, permit virus replication, and induce responses that recruit immune cells to the endothelium. Recent studies focused on dengue virus infection of primary ECs have demonstrated that ECs are efficiently infected, rapidly produce viral progeny, and elicit immune enhancing cytokine responses that may contribute to pathogenesis. Furthermore, infected ECs have also been implicated in enhancing viremia and immunopathogenesis within murine dengue disease models. Thus dengue-infected ECs have the potential to directly contribute to immune enhancement, capillary permeability, viremia, and immune targeting of the endothelium. These effects implicate responses of the infected endothelium in dengue pathogenesis and rationalize therapeutic targeting of the endothelium and EC responses as a means of reducing the severity of dengue virus disease.
