title: Epidemiological study of rickettsial infections in patients with hypertransaminemia in Madrid (Spain).
abstract: A retrospective analysis was performed to detect anti-rickettsial antibodies in the serum of patients with hypertransaminemia of unknown etiology, and in that of healthy members of the general population of Madrid (Spain). Among 143 patients 16 (11.2%) were positive for anti-R. conorii IgG antibodies and 7% for R. typhi. PCR analysis was performed in patients with IgM antibodies. Among 143 healthy subjects from the general population, seven (4.9%) were positive for anti-R. conorii IgG antibodies, and 2.8% for R. typhi. These results show that anti-rickettsial antibodies are more commonly detected in patients with hypertransaminemia than in healthy people.
