Chlamydia and the Curtis-Fitz-Hugh syndrome.

Ten women with acute right upper-quadrant abdominal pain but negative results for biliary investigations had a current or past history of pelvic inflammatory disease. A diagnosis of the Curtis-Fitz-Hugh syndrome was made and was confirmed in five patients by laparoscopy. Neisseria gonorrhoeae was not isolated from the cervical and urethral swabbings of seven patients tested. Chlamydia trachomatis was isolated from the endocervical canal in one of six patients examined. Of sera from nine patients tested by a micro-immunofluorescence test, nine and six samples respectively showed type-specific IgG and IgM antibodies against C trachomatis serotypes D-K. Type-specific IgG and IgA antibodies were also detected in the cervical and urethral discharge of two out of five patients and in the peritoneal aspirate of two. The presence of high titres of IgG or IgM in sera and IgG or IgA in the local discharges of our patients suggests that C trachomatis was probably the cause of the CFH syndrome.
