To compare the sensitivity of a new ELISA for IgM antibodies to Borrelia burgdorferi that uses a recombinant outer surface protein C (rOspC) with those of a whole cell (WC) ELISA and an immunoblot assay for the diagnosis of early Lyme disease, serum specimens from 82 consecutive patients with physician-documented erythema migrans were analyzed. To compare the specificities of the three assays, serum specimens from 50 patients without a history of Lyme disease and from an area in which B. burgdorferi is not endemic were analyzed. The sensitivities of the WC ELISA, immunoblot assay, and IgM rOspC ELISA were 28%, 29%, and 46%, respectively, while the specificities were 100%, 100%, and 98%, respectively. The IgM rOspC ELISA is a convenient, readily automated, easily standardized serologic test that is significantly more sensitive for the diagnosis of early Lyme disease than either WC ELISA or immunoblot assay.

A new measure to assess behavioral, affective and somatic outcomes in the acute phase of bone marrow transplant is described. The Behavioral Affective and Somatic Experiences Scale (BASES) is a 38 item nurse-report instrument, with five subscales labeled Somatic distress, Compliance, Mood/Behavior, Interactions, and Activity. A series of pilot studies were conducted to refine the content of the BASES scale and to establish its psychometric properties in terms of internal consistency, inter-rater reliability, and validity. Internal consistency (Chronbach's alpha) for the subscales ranged from .742 to .902. Inter-rater reliability was good, with a median correlation between paired nurse observations of .866. A parent report version of the BASES scale has also been developed, and the finding of significant parent-nurse correlations provides preliminary evidence of the validity of the measure. Potential uses of the BASES scale in the pediatric BMT setting are discussed. [ABSTRACT FROM AUTHOR] more...
