Nephropathia epidemica (NE) is a hemorrhagic fever with renal syndrome (HFRS) normally taking a benign clinical course. The etiologic agent, Puumala hantavirus is genetically closely related to Sin Nombre virus, which causes a frequently lethal febrile syndrome with pulmonary involvement (hantavirus pulmonary syndrome, HPS). HPS is characterized by acute respiratory distress, non-cardiogenic pulmonary edema and severe and hypotension, but usually no significant renal involvement. Pulmonary involvement and respiratory symptoms also occur in NE. To understand the mechanisms of pulmonary involvement in NE, we studied the clinical records and chest X-rays of 125 hospital-treated acutely ill NE patients. Twenty-eight percent of the patients had disease-related changes in their chest radiographs. Pleural effusion and atelectasis were the most common X-ray findings, whereas frank pulmonary edema was rare. The patients with pathologic X-ray findings had a more marked hypoproteinemia (lowest measured serum protein concentration 54 +/- 1 g/l) than those with normal X-ray (62.1 +/- 0.9 g/l, p < 0.001) and leukocytosis (highest measured blood leukocyte count 14.1 +/- 0.9 x 10(9)/l vs. 10.6 +/- 0.6 x 10(9)/l, p < 0.001) and more severe renal insufficiency (highest measured serum creatinine 590 +/- 60 mumol/l vs. 356 +/- 29 mumol/l, p < 0.05). Hypoproteinemia best predicted the occurrence of abnormal chest X-ray findings in NE. This suggests, that capillary leakage and inflammation may play a role in the pathogenesis of NE lung involvement, similarly as in HPS. Differently from HPS, the fluid volume overload associated with renal insufficiency seemed to contribute strongly to the chest X-ray changes in NE.

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.

The case definition for dengue hemorrhagic fever (DHF) requires fever, platelets < or = 100,000/mm3, any hemorrhagic manifestation, and plasma leakage evidenced by hemoconcentration > or = 20%, pleural or abdominal effusions, hypoproteinemia or hypoalbuminemia. We evaluated the specificity and yield of modified DHF case definitions and the recently proposed World Health Organization criteria for a provisional diagnosis of DHF, using a data base of laboratory-positive and laboratory-negative reports of hospitalizations for suspected dengue in Puerto Rico, 1994 to 1996. By design, all modifications had 100% sensitivity. More liberal criteria for plasma leakage were examined: 1) adding as evidence a single hematocrit > or = 50% (specificity 97.4%); 2) accepting hemoconcentration > or = 10% (specificity 90.1%); and 3) accepting either hematocrit > or = 50% or hemoconcentration > or = 10% (specificity 88.8%). The new DHF cases identified by these definitions (and percent laboratory positive) were 25 (100.0%), 95 (90.5%), and 107 (91.6%), respectively. In contrast, the provisional diagnosis of DHF (fever and hemorrhage, and one or more of platelets < or = 100,000/mm3, or hemoconcentration > or = 20%, or at least a rising hematocrit [redefined quantitatively as a 5% or greater relative change]) showed a specificity of 66.8%, and identified 318 new DHF cases, of which 282 (88.7%) were laboratory-positive. Very small changes in the criteria may result in a large number of new cases. The modification that accepted either hematocrit > or = 50% or hemoconcentration > or = 10% had acceptable specificity, while doubling the detection of DHF-compatible, laboratory-positive severe cases, but "provisional diagnosis" showed even lower specificity, and may produce inflated DHF incidence figures. Modified case definitions should be prospectively evaluated with patients in a health-care facility before they are recommended for widespread use.
