Clinical observations were made on 95 serologically or virologically confirmed dengue fever cases during an epidemic in a rural area of Indonesia in December 1976. The age distribution was similar to that observed in patients with dengue hemorrhagic fever in Jakarta, a highly endemic urban area. The observed disease ranged in severity from undifferentiated fever to shock and death. The majority of patients had acute onset of fever with nausea, vomiting, headache, and abdominal pain. Hepatomegaly was observed in only 19% of the patients. A positive tourniquet test was the most frequently observed hemorrhagic manifestation, but epistaxis was observed in 20% and hematemesis in 6% of the patients. Dengue shock syndrome was observed in 37% of the patients. There were four deaths, three of which were confirmed as due to dengue infection by virus isolation. The data suggest that one, and possibly two, of the fatal cases with virus isolation were primary infections, based on the results of hemagglutination-inhibition test using all four dengue antigens.

During the dengue 3 epidemic which occurred in French Polynesia between September 1989 and March 1990, number of cases of Dengue Haemorrhagic Fever (DHF) were reported among children and infants. Of interest, five cases of neonatal infections were recorded and involved the transmission of the virus from mother to child as the end of the pregnancy. Detailed observations on these cases are presented in this paper. Fever in mother, when delivering or just a few days before, represents the circumstances of the diagnosis. Analysis of the clinical features shows that fever and vasomotor troubles (blotches) were the dominating traits of the disease in the newborns. Also, hepatomegaly was constantly observed. Concerning the biological results, thrombopenia (platelets count: 100,000/mm3) was reported for all cases. According to these data, all cases were classified into DHF cases. Laboratory confirmation was obtained by serological investigations (antidengue IgM immunocapture ELISA and Haemagglutination Inhibition Tests) and/or virus isolation in both mother and child. Thus, virus was recovered in two newborns while IgM were detected in all infants and in four mothers. Severity of the disease was variable. However, out of five cases one fulfills the WHO definition of Dengue Shock Syndrome (DSC). Moreover, the authors discuss about the difficulties encountered to classify the cases according to WHO criteria for the grade classification of DHF.

Dengue virus infection (DVI) is endemic in tropical countries in both children and adults. The classical presentation includes fever, hepatomegaly, thrombocytopenia-related bleeding disorders, and plasma leakage. Multi-organ involvement, including kidneys is found in complex cases. Asymptomatic electrolyte disturbances, abnormal urinalysis, and more severe manifestation such as acute kidney injury (AKI) usually indicate kidney involvement. Such manifestations are not rare in DVI, but are often not recognized and can cause the physician to misread the real situation of the patient. The prevalence of electrolyte disturbances or kidney involvement reported in studies varies widely by country and mainly depends on the severity of DVI and age of the patients. The prevalence of DVI-induced AKI ranges from 0.2%-10.0% in children and 2.2%-35.7% in adults. The prevalence among all age groups appears to be increasing in the last decade. Dengue shock syndrome (DSS) has been reported to be an independent risk factor for AKI development. The mechanism of DVI-induced AKI is complex and the details are to date undetermined. Urinalysis, serum electrolytes and creatinine measurements should be performed to document renal involvement in DVI patients for early detection and initiation of appropriate fluid therapy with close monitoring. Renal replacement therapy may be required in some cases. The presence of AKI dramatically increases the mortality rate among both childhood and adulthood DVI from 12%-44% to more than 60%.
