Abstract
A LETHAL CASE OF VIRAL-BACTERIAL PNEUMONIA WITH RELATIVE LYMPHOPENIA: RETROSPECTIVE EVALUATION
Gradil G.I.
The author presents a clinical case of a fatal course of сommunity аcquired viral-bacterial pneumonia in a patient without underlying risk factors but with аtypical course. Lymphopenia and neutropenia development is considered a prognostic factor for severe course and the probability of a fatal outcome. Morphology demonstrated impairment of vascular endothelial cells, hypoplasia of the lymphoid follicles in the spleen, massive necrosis of the liver parenchyma with hemorrhages. At present such case should be differentiated with pneumonia caused by mycoplasmas, legionella, rickettsias, chlamydia, pneumocystis, as well as, in the presence of epidemiological data, with influenza A (H1N1) California 2009, influenza H5N1, coronaviral infection (MERS-CoV), that is infections complicated with acute respiratory distress syndrome (ARDS). The mechanisms of neutropenia and lymphopenia development in viral lesions of the respiratory system require further inverstigation.

СМЕРТЕЛЬНИЙ ВИПАДОК ВІРУСНО-БАКТЕРІАЛЬНОЇ ПНЕВМОНІЇ З ВІДНОСНОЮ ЛІМФОПЕНІЄЮ: РЕТРОСПЕКТИВНА ОЦІНКА.

Автор представляє клінічний випадок фатального перебігу захворювання, викликаного вірусно-бактеріальною пневмонією, у пацієнта без основних факторів ризику, але з нетиповим перебігом. Розвиток лімфопенії, нейтропенії розглядається як прогностичний фактор для важкого перебігу і ймовірності летального наслідку. При морфологічному дослідженні відзначалося ушкодження судинних ендотеліальних клітин, гіпоплазія лімфоїдних фолікулів в селезінці, масивний некроз паренхіми печінки з крововиливами. Дифференційна діагностика сьогодні в клінічній ситуації, що подібна описаному випадку, повинна проводитись з пневмоніями, які обумовлені мікоплазмами, легіонелами, рикетсіями, хламідіями, пневмоцистами, а також, за наявності епідеміологічних даних, з грипом A (H1N1) California 2009, грипом H5N1, коронавірусною інфекцією (MERS-CoV) - тобто з інфекціями, які ускладнюються гострим респіраторним дистрес синдромом (ГРДС). Механізми розвитку нейтропенії, лімфопенії при вірусному ураженні респіраторної системи потребують подальшого вивчення.
