Abstract
BACKGROUND Fifty cases of fever, clinically suspected to be dengue were studied. METHODS Complete clinical, haematological evaluation and IgM capture assay was done. RESULT 54% of patients clinically suspected to have dengue were positive for IgM antibodies by enzyme-linked immunosorbent assay (ELISA). The commonest clinical feature was fever with rash (85%). Thrombocytopenia was seen in 19% of patients only. One patient died of dengue shock syndrome (DSS). CONCLUSION Out of the 27 cases of seropositive dengue there was one death due to dengue shock syndrome. Thrombocytopenia may not always be a feature of dengue.

Abstract
Plasma leakage is one of the characteristic features of dengue haemorrhagic fever. The interaction among peripheral blood mononuclear cells (PBMCs), dengue virus and endothelial cells was analysed in vitro. Human umbilical vein endothelial cells (HUVECs) were infected with dengue-2 virus (DV-2) at an m.o.i. of 0.5 p.f.u. per cell. PBMCs were added to DV-2-infected HUVECs, and transendothelial electrical resistance (TEER) and transalbumin permeability were assessed. Dengue virus infection at an m.o.i. of 0.5 p.f.u. per cell alone did not decrease the TEER, but addition of PBMCs decreased the TEER, increased the albumin permeability and induced morphological changes of HUVECs. The extent of the decrease was more profound with adherent PBMCs than with non-adherent PBMCs. The expression of vascular endothelial cadherin (VE-cadherin) was examined using real-time RT-PCR and immunofluorescence. Addition of PBMCs to DV-2-infected HUVECs decreased the levels of mRNA transcripts and cell-surface expression of VE-cadherin. The results indicate that PBMCs increased the permeability of DV-2-infected HUVECs and that the increased permeability was concomitant with morphological change and the decrease in VE-cadherin expression. The results suggest that functional impairment of the DV-2-infected HUVEC monolayer was caused by interaction with PBMCs.

Abstract
This review is an update of dengue and dengue haemorrhagic fever (DHF) based on international and Cuban experience. We describe the virus characteristics and risk factors for dengue and DHF, and compare incidence and the case fatality rates in endemic regions (southeast Asia, western Pacific, and the Americas). The clinical picture and the pathogenesis of the severe disease are explained. We also discuss the viral, individual, and environmental factors that determine severe disease. Much more research is necessary to clarify these mechanisms. Also reviewed are methods for viral isolation and the serological, immunohistochemical, and molecular methods applied in the diagnosis of the disease. We describe the status of vaccine development and emphasise that the only alternative that we have today to control the disease is through control of its vector Aedes aegypti.

Abstract
The study was undertaken to elucidate the sequence of appearance of T helper (Th)1- and Th2-type cytokines in human peripheral blood leucocyte cultures infected in vitro with dengue type 2 virus. Commercial sandwich enzyme-linked immunosorbent assay kits were used to assay the levels of tumour necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), interleukin (IL)-2, IL-4, IL-5, IL-6, and IL-10 in culture supernatants. Culture supernatants were also screened for the cytotoxic factor and the dengue virus titres determined. The cytokines that appeared in the culture supernatants on the first day post-infection (p.i.) were cytotoxic factor, TNF-alpha, IL-2, and IL-6; their levels were highest on the second day p.i. IFN-gamma appeared on the second day with a peak on the third day p.i. The levels of these cytokines declined quickly, except for human cytotoxic factor (hCF) and IL-2. The cytokines that appeared later were IL-10 and IL-5 on the fourth day and IL-4 on the sixth day p.i. Dengue virus replicated in the peripheral blood leucocyte (PBL) cultures and was present throughout the course of the study. The findings of the present study show that dengue virus induced a predominant Th1-type cytokine response during the first 3 days of infection of PBL cultures that was replaced by a Th2-type response later.

Abstract
A unique cytokine, human cytotoxic factor (hCF), has been shown to occur in the sera of patients with dengue fever (DF) and dengue haemorrhagic fever (DHF). The present study was undertaken to investigate the ability of fresh PBMC of such patients to produce hCF. The PBMC were cultured for 24 h and the culture supernatants (CS) were analysed for the presence of hCF by cytotoxicity assay, competitive ELISA and dot blot tests. In 90% of 246 cases CS were positive for hCF by the three tests. CS were positive for hCF in PBMC collected from days 1-20 of illness but not at later periods. Higher cytotoxic activity was observed in CS of days 1-4 of illness and was highest in cases of DHF grade IV and lowest in cases of DF. Dot blot hybridization of RNA extracted from the PBMC of the patients showed the presence of mRNA for hCF in 94% of cases. A similar number of patients showed the presence of hCF in situ in the PBMC smears by fluorescent antibody technique. hCF was found only in CD4+ T cells. The findings thus present direct evidence of the production of hCF by CD4 T cells of cases of DF/DHF.

Abstract
We studied 17 consecutive patients of Dengue Haemorrhagic Fever/Dengue Shock Syndrome (DHF/DSS) to assess cardiac function by radionuclide ventriculography, echocardiography and electrocardiography (ECG) during the epidemic of Dengue virus type-2 (DEN-2) in Delhi, India (1996). Case definitions laid down by the WHO were followed. Fourteen patients were seropositive for Dengue infection. In radionuclide ventriculography study, the mean left-ventricular ejection fraction was 41.69 (5.04% (range 33-49%) and 7 patients had an ejection fraction less than 40%, global hypokinesia was detected in 12 (70.59%) patients. In echocardiography, the mean ejection fraction was 47.06 (3.8%). Eight patients had Dengue Shock Syndrome and the mean ejection fraction was 39.63% (4.97% in radionuclide ventriculography, out of which 5 patients had an ejection fraction below 40%. To find out the nature of myocardial involvement, 99m Tc-pyrophosphate imaging was done in 4 patients and it was discontinued further because no myocardial necrosis was detected in those patients. Five patients had ST and T changes in the electrocardiogram, radionuclide ventriculography and echocardiography revealed no abnormalities after 3 weeks of follow up and the ejection fraction was more than 50% in all cases. Global hypokinesia also improved and ECG changes reverted back to normal within 3 weeks. Acute reversible cardiac insult may be noticed in Dengue Haemorrhagic Fever/Dengue Shock Syndrome and could be responsible for hypotension/shock seen in some of these patients. Further studies are required to establish the pathogenic mechanisms of cardiac dysfunction in patients with Dengue Haemorrhagic Fever/Dengue Shock Syndrome.

Abstract
Three cases of dengue fever involving the central nervous system (CNS) are reported. All occurred in 1994 during a dengue (DEN) epidemic caused by serotypes DEN-1 and DEN-2. The first case examined was a 17-year-old girl who complained of fever, nuchal rigidity and genital bleeding. Three blood samples were positive by anti-dengue IgM ELISA and showed hemagglutination-inhibition (HI) test titers > or = 1,280. The second case concerned a 86-year-old women with fever, muscle and joint pains, altered consciousness, syncope, nuchal rigidity and meningismus. Her blood sample showed an HI titer of 1:320 for flaviviruses, and an IgM ELISA positive for dengue. The third case was a 67-year-old women with fever, abnormal behaviour, seizures, tremor of extremities, thrombocytopenia, increased hematocrit and leukopenia. The patient suffered a typical case of dengue hemorrhagic fever with ensuing shock and a fatal outcome. A single blood sample showed HI antibodies of > or = 1,280 and an IgM ELISA positive for dengue. No virus could be isolated from any patient by inoculation of blood into C6/36 cells and suckling mice. No other agent of disease was encountered in the patient.

Abstract
Specific active immunization with dengue type 2 virus (DV)-induced cytokine, cytotoxic factor (CF), prevents CF-mediated pathology in mice. The present study was undertaken to determine the optimum dose of CF and the effect of different adjuvants on the immune response as assessed by the study of anti-CF antibody titre by ELISA and protection against increase in capillary permeability to challenging dose of 3 micrograms CF. The maximum protection of 94 +/- 4% against increase in capillary permeability was observed at week 4 after immunization with 5 micrograms dose of CF mixed with Freund's incomplete adjuvant (FIA), which gradually decreased to 21 +/- 10% on week 24. With a dose of 10 micrograms the protection obtained was 79 +/- 5%, but persisted for a longer time at a higher level. The response was poor with 1 microgram dose of CF. The mean anti-CF antibody titres gradually decreased after reaching the peak at week 4 after immunization. Mice immunized with different adjuvants emulsified with 5 micrograms CF were challenged at different intervals with 3 micrograms CF. Maximum protection observed with CF + tetanus toxoid (TT) and 84/246 was about 93 +/- 2% and 97 +/- 2%, while that with alhydrogel was 33 +/- 12% and with bacille Calmette-Guérin (BCG) was 67 +/- 4%. At week 24 after immunization, however, the best response was obtained with 10 micrograms of adjuvant 84/246. Intracerebral challenge with 10 or 100 LD50 dose of dengue type 2 virus showed significantly prolonged mean survival time and delayed onset of signs of sickness in immunized mice compared with normal mice. The maximum survival time was with adjuvant 84/246 even at week 24. The findings thus show that the optimum dose of CF is 5 micrograms and the adjuvant of choice is 84/246.
