Hantavirus Pulmonary Syndrome: A Clinical Description of 17 Patients with a Newly Recognized Disease

Abstract: Background In May 1993 an outbreak of severe respiratory illness occurred in the southwestern United States. A previously unknown hantavirus was identified as the cause. In Asia hantaviruses are associated with hemorrhagic fever and renal disease. They have not been known as a cause of human disease in North America. Methods We analyzed clinical, laboratory, and autopsy data on the first 17 persons with confirmed infection from this newly recognized strain of hantavirus. Results The mean age of the patients was 32.2 years (range, 13 to 64); 61 percent were women, 72 percent were Native American, 22 percent white, and 6 percent Hispanic. The most common prodromal symptoms were fever and myalgia (100 percent), cough or dyspnea (76 percent), gastrointestinal symptoms (76 percent), and headache (71 percent). The most common physical findings were tachypnea (100 percent), tachycardia (94 percent), and hypotension (50 percent). The laboratory findings included leukocytosis (median peak cell count, 26,000 per cu...

Hantavirus Pulmonary Syndrome: Pathogenesis of an Emerging Infectious Disease

Abstract: A recent outbreak of a severe pulmonary disease in the southwestern United States was etiologically linked to a previously unrecognized hantavirus The virus has been isolated from its major reservoir, the deer mouse, Peromyscus maniculatus, and recently named Sin Nombre virus Clinically, the disease has become known as the hantavirus pulmonary syndrome (HPS) Since May 1993, 44 fatal cases of HPS have been identified through clinicopathological review and immunohistochemical (IHC) testing of tissues from 273 patients who died of an unexplained noncardiogenic pulmonary edema In 158 cases for which suitable specimens were available, serological testing and/or reverse transcription-polymerase chain reaction (RT-PCR) amplification of extracted RNA was also performed IHC, serological, and PCR results were concordant for virtually all HPS and non-HPS patients when more than one assay was performed The prodromal illness of HPS is similar to that of many other viral diseases Consistent hematological features include thrombocytopenia, hemoconcentration, neutrophilic leukocytosis with a left shift, and reactive lymphocytes Pulmonary histopathological features were similar in most of the fatal HPS cases (40/44) and consisted of an interstitial pneumonitis with a variable mononuclear cell infiltrate, edema, and focal hyaline membranes In four cases, however, pulmonary features were significantly different and included diffuse alveolar damage and variable degrees of severe air space disorganization IHC analysis showed widespread presence of hantaviral antigens in endothelial cells of the microvasculature, particularly in the lung Hantaviral antigens were also observed within follicular dendritic cells, macrophages, and lymphocytes Hantaviral inclusions were observed in endothelial cells of lungs by thinsection electron microscopy, and their identity was verified by immunogold labeling Virus-like particles were seen in pulmonary endothelial cells and macrophages HPS is a newly recognized, often fatal disease, with a spectrum of microscopic morphological changes, which may be an important cause of severe and fatal illness presenting as adult respiratory distress syndrome

Improvements in Diabetes Processes of Care and Intermediate Outcomes: United States, 1988–2002

Abstract: statistically significant increase of 21.9% (CI, 12.4% to 31.3%). Mean LDL cholesterol level decreased by 0.5 mmol/L (18.8 mg/ dL). Although mean hemoglobin A1c did not change, the proportion of persons with hemoglobin A1c of 6% to 8% increased from 34.2% to 47.0%. The blood pressure distribution did not change. Annual lipid testing, dilated eye examination, and foot examination increased by 8.3% (CI, 4.0% to 12.7%), 4.5% (CI, 0.5% to 8.5%), and 3.8% (CI, 0.1% to 7.7%), respectively. The proportion of persons reporting annual influenza vaccination and aspirin use improved by 6.8 percentage points (CI, 2.9 percentage points to 10.7 percentage points) and 13.1 percentage points (CI, 5.4 percentage points to 20.7 percentage points), respectively.

Primary Care Guidelines for the Management of Persons Infected with Human Immunodeficiency Virus: 2009 Update by the HIV Medicine Association of the Infectious Diseases Society of America

Abstract: Evidence-based guidelines for the management of persons infected with human immunodeficiency virus (HIV) were prepared by an expert panel of the HIV Medicine Association of the Infectious Diseases Society of America. These updated guidelines replace those published in 2004. The guidelines are intended for use by health care providers who care for HIV-infected patients or patients who may be at risk for acquiring HIV infection. Since 2004, new antiretroviral drugs and classes have become available, and the prognosis of persons with HIV infection continues to improve. However, with fewer complications and increased survival, HIVinfected persons are increasingly developing common health problems that also affect the general population. Some of these conditions may be related to HIV infection itself and its treatment. HIV-infected persons should be managed and monitored for all relevant age- and gender-specific health problems. New information based on publications from the period 2003‐2008 has been incorporated into this document.
