[The diagnostic significance of antibodies to lipid A in patients with chronic kidney infections].

The interest in antilipid A antibodies increases in recent years. By means of an immunoenzyme test developed by the authors the frequency, quantity and characteristic of these antibodies were studied in 46 patients with chronic renal infections and in 36 healthy controls. The frequency of antilipid A antibodies class IgM is 5.7% and of class IgG it is 2.8% in the control group (healthy persons) and it is 41.3% and 19% respectively in the renal patients group. Most frequently their presence and quantity correlate with an active infection or with the convalescent period following antibiotic treatment (62.5%). This allows the use of antilipid A antibodies as a confirming marker for the presence of a heavy Gram negative infection and as a possible index for evaluation the efficacy of the treatment.
