Case 6 - ecp23, Infectious Diseases Pathology
Presented by: Vsevolod Zinserling, Saint-Petersburg, Russian Federation

Male patient Ivan V, 31 ys old., before the last illness healthy, but with obesity. Got ill acute, with fever till 39 degrees C. Was hospitalized on the 3 day in the intensive care unit in severe condition caused by respiratory insufficiency, where intubation and later on tracheostomy were done. The clinical diagnosis of “swine influenza” was supported by RT PCR and serology (increase of antibody level 0-640). In spite of intensive treatment including antibiotics and antiviral drugs, patient died on the 35th day of the illness.

At the autopsy remarkable changes were found only in the lungs: necrotic posttrachestomic tracheitis, large abscesses in the lower lobes of the lungs in the stage of organization, bilateral fibrinous pleuritis. The rest of lung tissue was dark red, firm.

During the histological examination in the lungs were noted changes typical for rather old abscesses, late stages of respiratory distress syndrome. The changes typical for influenza (virus induced transformation of epithelial cells) were expressed only in the moderate number of the cells. We notified numerous intraalveolar macrophages, partly with vacuolated cytoplasma, and PAS-positive inclusions. Some cells had slightly enlarged hyperchromic nuclei. Similar changes were noted in other organs as well.

Postmortem RT PCR in lungs and spleen for influenza A H1N1 swine (-). Postmortem bacteriology of lungs: E.coli, nonpathogenic corynebacteria, enterococcus, S. viridans and S.epidermiditis.

During the immunohistochemical investigation we notified in lungs strong positive reaction with serum against Chlamydia trachomatis, moderate against adenovirus and weak against influenza H1N1. The reactions with sera against HSV1/2, CMV, EBV, RS, entero- and parvoviruses, Mycoplasma pneumoniae were negative.

During the electron microscopic investigation of lungs we succeeded to evaluate numerous elementary and reticular bodies of Chlamydia, in brain only reticular ones predominantly in cytoplasma of endothelial cells. In their nuclei several PML –nuclear bodies were found.
