[Pyogenic infectious complications in recipients with allogenic kidneys: clinical and bacteriological aspects]

The bacteriological study of wound discharge indicated no changes in the structure of the microflora in the allogenic kidneys of recipients throughout the follow-up. Among microbes isolated there were prevalent gram-positive microbes whose proportion has slightly increased in the past year, with Staphylococcus, mainly epidermal Staphylococcus, which contributes to the etiology. At the same time, studies of wound discharge in the past years showed that the incidence of mixed infections had increased from 4.3 in 1989-1991 to 15.6% in 1994-1997. Bacteriological urinalysis found no great differences in the etiological structures of the microflora. Gram-negative microbes are prevalent in all patients in three periods of follow-up. Noteworthy, there was an increase in the amount of yeast fungi (from 5.7 to 21.1%). Urinalysis showed that the rates in the isolation of bacterial and bacterial and fungal associations were steady-state and higher in all patients (20, 4-23, 5%). Examining the etiological structure of the pathogens of sepsis ascertained that patients of the early observation were found to isolate gram-negative microorganisms more frequently, while those of other observation periods have gram-positive ones. The overall proportion of microbial and microbe-fungal associations was 10.3% in the past 9 years. Since the patient's body is occupied by other pathogens due to immunosuppression, sepsis or wound infection was accompanied by high bacteriuria, cytomegalovirus infection, pneumocystic pneumonia, fungal infection, etc. For this reason, the patients had actually much higher quantities of mixed infections in sepsis, wound infection, or urinary infection than those taken into account while studying the only type of an infectious complication. The above leads to the conclusion that the incidence of mixed infection of recipients of allogenic kidneys is rather high. This infection substantially makes the choice of drugs and therapy difficult, the course of a wound process aggravated. For successful control of mixed infections, it is necessary to introduce new drugs having a high activity against bacteria, fungi, viruses, and protozoa and to use the latest differentially diagnostic culture media, to make diagnosis and treatment of pyoseptic diseases better.
