Severe respiratory distress developed in a patient after ingestion of two tablets of erythromycin (Erythrocin) stearate. Complete atelectasis of the left lung was found. ⋯ Using the indirect mast cell degranulation test and the inhibition of direct mast cell degranulation test, we have shown the presence of IgE and non-IgE antibodies (heat stable) against erythromycin. This suggests that an allergic reaction of type 1 and type 3 participated in the course of the clinical picture.

In selected patients, detection of antibody-coated bacteria (ACB) in voided urine has correlated with upper urinary tract infection. From unselected patients, we studied 350 consecutive urine specimens submitted to the diagnostic laboratory with colony counts greater than or equal to 10(5)/ml. In 19% (55) among 288 specimens selected for final analysis ACB occurred. ⋯ The relationship of ACB to clinical syndromes was: asymptomatic bacteriuria, 15% (27/178); cystitis, 8% (6/75); acute hemorrhagic cystitis, 67% (4/6); prostatitis, 67% (2/3); and acute pyelonephritis, 62% (16/26). Among seven clinical findings, only structural abnormalities of the upper urinary tract correlated with the presence of ACB. Failure of fever and leukocytosis to correlate with ACB probably reflected the presence of other associated primary medical or surgical conditions.
