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.

Clinical and serological studies were carried out on 114 patients admitted to hospital in Havana, Cuba with Dengue Haemorrhagic Fever and Dengue Shock Syndrome (DHF/DSS). Serological confirmation of dengue was obtained in 90% of cases, with 5% of cases primary and 95% secondary. Fever, haemorrhagic manifestations, vomiting and headache were the most frequent signs and symptoms. Among haemorrhagic manifestations, petechiae and vaginal bleeding were reported in a larger number of patients. 21 patients presented shock and, of these, 20 were secondary infections. The disease appeared more frequently in white persons and in women. The aetiopathogenicity of the syndromes is discussed. 95% of the cases could be explained on the basis of the secondary infection hypothesis.

One hundred and ten adult patients hospitalized with dengue haemorrhagic fever (DHF) during the recent outbreak in North India were prospectively studied. Of these, 48 (43.6%) were grade I, 40 (36.4%) grade II, 10 (9.1%) grade III and 12 (10.9%) grade IV DHF. Dengue shock syndrome (DSS) was seen in 22 (20%) patients. Fever, headache, myalgias and arthralgias were the common symptoms seen in 100%, 80.9%, 76.2% and 52.3% patients, respectively. Spontaneous bleeding was seen in 62 patients (56.4%) with mucocutaneous bleeding being the most common (46 patients). Gastrointestinal bleeding was seen in 38 (34.5%) patients. In as many as 40 patients, the haemorrhagic manifestations occurred after the fever had come down. Fifty-five patients (50%) required platelet transfusions. Twelve patients died, giving a mortality rate of 10.9% in the present study. Prompt recognition and supportive treatment can be lifesaving.

A dengue epidemic is one of the most important public health problems in the tropical and subtropical areas of the World. In 2005, 7,062 dengue cases were reported in Tamaulipas on Mexico's eastern coast, including 1,832 (26%) cases classified as Dengue Hemorrhagic Fever (DHF). Dengue fever (DF) is characterized by fever, intense headache, myalgias, arthralgias, rash, nausea and vomiting. A proportion of infected persons may develop DHF characterized by prominent hemorrhagic manifestations associated with thrombocytopenia. An immune mechanism of thrombocytopenia due to increased platelet destruction appears to be operative in patients with DHF. Excessive capillary permeability may lead to Dengue Shock Syndrome (DSS). Patients with DHF/DSS who also have prolonged fever (> 5 days) are at high risk for concurrent bacteremia. Standard treatment is limited to electrolytic solutions, rest, measurements of body temperature, blood pressure, hematocrit, platelet count, and administration of antipyretics like paracetamol when fever is too high. Extracellular calcium plays a key role in platelet aggregation and for the regulation of the immune response in personsinfected with Dengue Virus (DV), and dihydroxy-vitamin D has recently been found to alter IL-12 expression anddendritic cell maturation. We report the cases of five patients who received oral calcium carbonate plus Vitamin D3, who improved overall clinical condition and reduced the duration of signs and symptoms of DF.
