[Value of antibody coated bacteria in the localization and follow-up of chronic urinary tract infections (author's transl)].

Antibody coating of urinary bacteria was performed in order to localize the site of recurrent urinary tract infections in 39 para or tetraplegics. The antibody-coated bacteria test was positive with anti human globulin in 19 out of 39 patients: upper urinary tract infections 7/10, prostatitis 3/3, lower urinary tract infections 9/26. Of the 19 patients with positive antibody-coated bacteria test 14 were tested with monospecific antisera: 13 were IgG positive and 11 were IgA positive; IgM was never present. Among the 11 IgA positive tests, we search for the presence of IgA secretory piece in 8 and all were positive. The immunoglobulins on the bacterial wall result, in part, from local production of urinary antibody. Although positive results with anti human globulins occurred frequently in patients with lower urinary tract infections, this test appears to be a useful screening test for localization of infection in patients with recurrent urinary tract infection.

[Ocular localization appearing in a child with acute lymphoblastosis after hematological remission for 18 months].

Case report of a 4-year-old girl in whom a unilateral ocular localization appeared after 1 1/2 year of maintained remission of acute lymphoblastic leukaemia. The evolution of this localization can be divided in three phases: 1. During the first 17 months, an apparent simple relapsing conjunctivitis of the left eye. 2. During the following 5 months, repeated episodes of the left iritis with mydriasis and discolouration of the iris. 3. Finally, left uveitis involving the anterior chamber, with hypopion, hyphaema and glaucoma; the clinical presentation at this stage was suggestive of ocular lymphoblastosis. Radiotherapy to the lesion (total dose, 1 200 rads) was quickly followed by resolution without sequelae. No relapse was observed during the following 30 months, till death. The ocular disease remained the only manifestation of leukaemia during its evolution. A haematological relapse occurred 11 months after cure of the iritis, followed 1 year later by a second, treatment-sensitive relapse, and finally by a third, fatal relapse. The patient survived 5 years 9 months.
