[Pathogenesis of myocarditis in patients with bronchial asthma and pecilomycosis].

We studied the influence of activation ofpecilomycotic infection in blood on the morphofunctional state of myocardium based on the clinical and pathomorphological data. The study included 23 patients with bronchial asthma (BA) concomitant with pecilomycosis after acute viral respiratory infection; protocols of autopsies and pathological sections of the heart muscle of the patients who died from asphixy and acute cardiac insufficiency were analyzed. Histological sections showed up vascular dystonia of the microcirculation bed, arteriole spasms, wall destruction in small and medium-size vessels and the adjacent muscular tissue, stromal oedema, valvular swelling, andperiwall endocarditis. Cardiac cavities and coronary vessels contained erythrocyte-rich thrombi with ferulas of Paecilomyces at different stages of development. Clinical manifestations of destructive changes in the heart muscle developing under effect of Paecilomyces infection had the form of rhythm and conductivity disorders. The local protective inflammatory reaction of productive type had the form of intermediate and vascular-type myocarditis passing to postmyocarditic cardiosclerosis. Periodic bursts of activation ofpecilomycotic infection in blood with the accumulation of fungal phospholipase A2 and lipid metabolites produced membranotoxic effect and can play the key role in the development of atherosclerosis and hypertensive disease in patients with BA and pecilomycosis.

[HYPEREOSINOPHILIC SYNDROME ASSOCIATED WITH SEPSIS DUE TO PAECILOMYCES FUNGI DISSEMINATED INTO THE LIVER].

A 49 year old woman with signs of chronic sepsis, hepatomegaly, and high eosinophil count was under long-term examination including consultations with an oncologist, parasitologist, and hematologist, diagnostic laparotomy, and studies of liver biopsies. Seeding blood samples onto Saburo's medium resulted in the growth of Paecilomyces variotii Bainier colonies. Counting mature spherules of the fungus revealed 59000 spherules per 1 mcl compared with the normal value of 1000-6000 which suggested paecilomycotic etiology of sepsis. The histological study of liver biopsies demonstrated hemorrhagic foci and eosinophilic infiltrates around fungal spherules. The clinical recovery of the patient was achieved after 3 courses of pulsed terbinafine therapy (500 mg/d every other day for 14 days during a month) in combination with vitamins and i/v infusion of 100 ml of a fluconazole solution (2 mg/ml) every third day (10 procedures during a course of therapy).

[Genetic determinants of Escherichia coli pathogenicity isolated from urine and feces of children with different clinical variants of urinary system infection]. / Geneticheskie determinanty patogennosti Escherichia coli, izolirovannykh iz mochi i fekalii detei s razlichnymi klinicheskimi variantami infektsii mochevoi sistemy.

In the process of examination of 156 children of different age groups 176 E. coli cultures were isolated; of these, 98 cultures were isolated from acute cystitis and pyelonephritis patients, 28--from urine in cases of aysmptomatic bacteriuria, 30--from feces in cases of asymtomatc bacteriuria and intestinal dysbacteriosis, while 20 cultures--from feces of healthy children. In these bacteria the presence of genes associated with pathogenicity islets (PI) hlyA, hlyB, cnf-1, papC, sfaG and gene irp-2 (iron-regulated protein) was established with PCR. The detection rate of PI determinants in uropathogenic E. coli (UPEC) was shown to depend on the variants of the clinical manifestation of urinary tract infection. The total detection rate of PI gene fragments in UPEC cultures of different origin was indicative of their definitely less frequent occurrence in asymptomatic bacteriuria, observed simultaneously with intestinal dysbacteriosis, in comparison with acute urological infection. Practically the same detection rate of PI determinants in E. coli, isolated in asymptomatic bacteriuria in children, reflected high probability of genetic exchange in the above-mentioned fragments and made it possible to presume the existence of DNA sites, characteristic mainly of pathogenic clones. The established heterogeneity of the detection rate of PI determinants in E. coli clinical isolates requires further study.
