Thirty-seven serum samples and five serum-CSF pairs collected from 42 acutely ill patients admitted to hospitals in Maharashtra (Bombay, Pune and Nasik); Orissa (Raurkela) and South Goa were referred to the National Institute of Virology (NIV), Pune (Maharashtra, India) for serodiagnosis. These patients had clinical manifestations of fever, hemorrhagic manifestations, hepatomegaly, shock syndrome and encephalopathy. Sixty-six percent of patients were children below ten years of age. Serological investigations revealed infection to dengue virus in all the patients as indicated in detection of IgM antibodies predominantly to dengue viral antigens. An important outcome of the study is that 10 patients referred to NIV with a provisional diagnosis of viral encephalitis proved to be dengue.

During the months of September 1993 through February 1994, an outbreak of hemorrhagic fever occurred in the city of Jayapura, the provincial capital of Irian Jaya, Indonesia. Seventy-two patients (age range = 1-41 years) with suspected dengue hemorrhagic fever (DHF) were enrolled into the outbreak investigation conducted during October-November 1993. The pediatric patient population consisted of 36 individuals ages 1-12 years of age with a similar male to female ratio. From clinical histories obtained from the children diagnosed with DHF (n = 23), the predominant complaints were fever (100%), headache (96.7%), vomiting (47.8%), abdominal pain (39.1%), back/bone pain (39.1%), cough (39.1%), sore throat (21.7%), convulsions (17.4%), and eye pain (13.0%). Clinical findings of the same pediatric patients included a positive tourniquet test result (100%), thrombocytopenia (100%), hemoconcentration (100%), skin petechiae (43.5%), epistaxis (39.1%), and maculopapular rash (26%). All four of the children diagnosed with DHF grade IV had hepatomegaly, pleural effusion, ascites, cold perspiration, and confusion. Serologic data demonstrated that a majority (46 of 70, 68.7%) of the individuals assessed did not have significant levels of IgM specific for dengue viruses at the time of their admission. However, the nine successful dengue virus isolations were only from these serononreactive cases (19.6%). From the other patients assessed, 11.4% had a primary (or first exposure) serologic response to dengue virus antigen (predominantly IgM); 17.1% had a secondary (or subsequent exposure) serologic response to the same dengue antigens (predominantly IgG response) and 5.7% (four adults) had indeterminate serologic data that could not differentiate between reactivity to dengue or Japanese encephalitis virus antigen preparations. Virus culture of blood samples produced nine dengue virus isolates: DEN- 1 (2), DEN-2 (1), and DEN-3 (6). Japanese encephalitis and influenza viruses were not isolated from blood and pharyngeal specimens, respectively, from any of the patients. Thus, this first reported outbreak of DHF in Irian Jaya, Indonesia was found to be attributed to dengue viruses types 1, 2, and 3.

In a prospective study, the relationship between the clinical severity of dengue haemorrhagic fever (DHF) and the sonographic findings was examined. The study comprised 73 cases classified as mild (grades I-II) and 75 as severe (grades III-IV). Ultrasonography in the mild group revealed pleural effusions in 30%, ascites in 34%, gallbladder wall thickening in 32%, hepatomegaly in 49%, splenomegaly in 16%, and pancreatic enlargement in 14%. In the severe group, pleural effusions, ascites and gallbladder wall thickening were found in 95%, pararenal and perirenal fluid collections in 77%, hepatic and splenic subcapsular fluid collections in 9%, pericardial effusion in 8%, hepatomegaly in 56%, splenomegaly in 16%, and pancreatic gland enlargement in 44%. Ultrasound may be useful for early prediction of the severity of DHF in children.

A major outbreak of dengue hemorrhagic fever (DHF) affected more than 10,000 people in Delhi and neighboring areas in 1996. The outbreak started in September, peaked in October to November and lasted till early December. The clinical and laboratory data of 515 adult patients admitted to Lok Nayak Hospital, New Delhi were reviewed. Fever (100%), myalgias and malaise (96%), abdominal pain (10.2%) and vomiting (8.7%) were the prominent presenting features. Hemorrhagic manifestations were seen in all patients- a positive tourniquet test (21.2%), scattered petechial rash (23.07%), confluent rash (2.7%), epistaxis (38.4%), gum bleeds (28.06%) and hematemesis (22.86%) being the major bleeding manifestations. Hepatomegaly was observed in 96% of the patients. Laboratory investigations revealed thrombocytopenia, hemoconcentration and leukopenia. Serological confirmation with a microcapture ELISA technic was done in 143/515 patients. The mortality rate was 6.6% and, multiple bleeding manifestations, severe thrombocytopenia, hypoproteinemia and dengue shock syndrome (DSS) were associated with a higher mortality.

Dengue haemorrhagic fever/dengue shock syndrome (DHF/DSS) is a major cause of hospitalisation and mortality among children in South East Asia. We now report, for the first time, the occurrence of DHF/DSS in Trinidadian children. The presence of vomiting, abdominal pain and hepatomegaly in the setting of a dengue epidemic should alert clinicians to the possibility of DHF/DSS. Timely diagnosis and aggressive supportive treatment are essential for a successful outcome. Source reduction, vector control and community participation are also necessary to avert the South East Asian scenario from emerging in the Caribbean.

Hepatic functions of 61 children, diagnosed to have dengue infection (DI), aged 2 months to 12 years comprising 37 cases of dengue fever (DF), 16 with dengue hemorrhagic fever (DHF), and eight with dengue shock syndrome (DSS) were prospectively studied during the acute attack. Hepatomegaly (74 per cent), epistaxis (26 per cent), jaundice (25 per cent), and petechial rashes (18 per cent) were the common clinical manifestations of DI. On admission, levels of serum aspartate transaminase (AST), serum alanine transaminase (ALT) and serum alkaline phosphatase (AP) were raised in 80-87 per cent of children with hepatomegaly (group I) and 81 per cent of cases without hepatomegaly (group II). During the second week of hospitalization the proportion of cases with raised levels of AST, ALT, AP and serum bilirubin increased and the mean levels were significantly higher (p < 0.05) in both the groups. These levels gradually declined over the next 2-3 weeks. All the cases with DSS and DHF had raised AST, ALT and AP levels and the mean levels of these enzymes were significantly higher (p < 0.05) as compared to DF. Our results suggest a transient derangement of liver functions in childhood DI, more so in DSS and DHF, with or without hepatomegaly.

Sera were collected from a total of 122 children, comprising 117 cases with undifferentiated fever and 5 cases with dengue hemorrhagic fever (DHF), during June to September 1994 in Karachi, Pakistan. Sera were tested by the IgM-capture ELISA using dengue type 1 (D1), dengue type 2 (D2), West Nile (WN), and Japanese encephalitis (JE) viral antigens. Among 92 single sera from undifferentiated fever cases, IgM antibodies were detected in 5 cases by D1, 8 cases by D2, and 5 cases by WN antigens, respectively. Corresponding number of positives among 25 paired sera from undifferentiated fever cases were 3 by D1, 6 by D2, and 1 by WN antigen. Four out of 5 DHF cases possessed anti-D1 as well as anti-D2 IgM antibodies. Only a single DHF case was positive for anti-WN IgM antibodies. Anti-JE IgM antibodies were not detected in any of the tested serum specimens. Clinical manifestations of undifferentiated fever patients were generally non specific, but the percentage of children with anemia, hepatomegaly and splenomegaly was higher in patients possessing anti-dengue IgM antibodies than those without. Among the groups with anti-dengue IgM antibodies, those possessing only anti-D2 but not anti-D1 IgM antibodies showed higher percentages with cough, edema, and splenomegaly. The results indicated that up to 26% of the undifferentiated fever cases were caused by dengue virus infection in Karachi, Pakistan.

Dengue virus infection may remain asymptomatic or manifest as nonspecific viral infection to life threatening dengue hemorrhagic fever (DHF)/dengue shock syndrome (DSS). Patients with DHF/DSS have fever, hemorrhagic manifestations along with thrombocytopenia and hemoconcentration. Thrombocytopenia and hemoconcentration are distinguishing features between DHF/DSS and dengue fever (DF). Some patients with dengue fever may have significant bleed and mild thrombocytopenia but no hemoconcentration. These patients are labelled to have dengue fever with unusual bleeds. Laboratory findings in DHF/DSS include rising hematocrit, thrombocytopenia and transformed lymphocytes on peripheral smear. There may be increased transaminases, hyponatremia, transient increase in blood urea nitrogen and creatinine. In severe disease there may be lab evidence of dissemination intravascular coagulation. X-ray film of the chest may show pleural-effusion. Ultrasonogram of abdomen may detect thickened gall bladder wall with hepatomegaly and ascitis. In some patients there may be abnormality in electrocardiogram and echocardiogram. The diagnosis of DHF/DSS is based on typical clinical findings. For confirmation of dengue virus infection viral culture can be done on blood obtained from patients during early phase of illness. In later part of illness antibodies against dengue virus can be demonstrated by various techniques. The treatment of DF is symptomatic. For control of fever nonsteroidal anti-inflammatory drugs should be avoided. DHF/DSS are managed by intravenous fluid infusion with repeated monitoring of vital parameters and packed cell volume (PCV).

This paper describes the clinical findings in 206 patients with dengue fever (DF) or with dengue hemorrhagic fever (DHF) during the epidemic of 1996 at Lucknow. The age group affected most was 11 to 30 years and 21% of the patients were less than 10 years old. The male:female ratio was 1.9:1. The onset was abrupt in all the patients, severe frontal headache was observed in 97%, myalgia in 90%, skin rash in 40%, vomiting in 29% and arthralgia in knee and hip joints in 9%. Anuria was seen in two patients. Lymphadenopathy was noted in 14%, hepatomegaly in 4%, being associated with mild jaundice in one patient, and splenomegaly in 2% of the patients. Involvement of the heart and lungs was seen in one patient each and no case with encephalitis was recorded. Hemorrhages from various sites were observed in 54% patients and 17 patients had profound shock. The commonest bleeding site was gums. Profound shock was preceded by various warning signs, the commonest being sudden hypotension. Among the patients with profound shock the mortality was 47% while the overall fatality rate was 3.8%. A number of the risk factors existed for a long time in this part of the world, but what precipitated the present epidemic at this time, is not known.

The impact of dengue on liver function was studied on fifty serologically confirmed dengue cases admitted to Hospital Universiti Kebangsaan Malaysia (HUKM). Twenty-five of these patients had classic dengue fever (DF) and 25 had grade 1 or 2 dengue hemorrhagic fever (DHF). There were more (60%) DHF patients with hepatomegaly compared to DF (40%) but the difference was not statistically significant. Analysis of the liver profile showed that liver dysfunction was commoner in DHF compared to DF, indicating that the degree of liver impairment may be related to the severity of DHF. Hyperbilirubinemia was noted in 3 (12%) DHF and 2 (8%) DF patients. The mean (range) serum bilirubin was higher in DHF [14.2(5-50) micromol/l] compared to DF [10.9(5-30) micromol/l)] (p > 0.05). Elevated levels of serum alanine aminotransferase (ALT) and alkaline phosphatase (ALP) were observed more frequently in DHF (20 and 12 patients respectively) compared to DF (16 and 8 patients respectively). Nine (36%) DHF and 6 (24%) DF patients had concomitant elevation of ALT and ALP levels. The mean (range) serum ALT levels were 109.3(23-325) U/l in DHF and 90.8(13-352) U/l in DF (p > 0.05). The mean (range) serum ALP levels were 102.2(15-319) U/l in DHF and 93.3(34-258) U/l in DF (p > 0.05). The ALT and ALP levels were significantly higher in DHF patients with spontaneous bleeding than those without bleeding (p < 0.05) None of the patients developed fulminant hepatitis. The immunoregulatory cells, which include the T (CD3), B (CD 19), CD4, CD8, CD5 and natural killer (NK) cells were significantly lower in DHF compared to DF patients (p < 0.05). However, the reduction in these cell counts did not correlate with the liver dysfunction seen in DHF patients. In conclusion, hepatomegaly and liver dysfunction were commoner in DHF compared to DF.
