Varicella-zoster virus pneumonia in adults: report of 14 cases and review of the literature.

Abstract：

:BACKGROUND: The aim of this retrospective study was to determine the clinical, laboratory, and radiological features of all adult patients with varicella-zoster virus pneumonia (VZVP) treated in our departments during the last 5 years. Important therapeutic and evolutionary features are also reported. METHODS: Fourteen patients (11 males and 3 females, mean age OF 36.4 and 34.3 years, respectively), diagnosed as suffering from VZVP, were included in this study. The antecedents of previous contact with patients with varicella, smoking, pregnancy, and underlying diseases were evaluated. In all cases, the diagnosis of pneumonia was established by clinical and radiological criteria in the course of varicella infection. RESULTS: All but one patient had had previous contact with a varicella patient. Eleven of them (78.57%) were smokers. None of the patients was immunocompromised. All patients had the characteristic rash of the disease, fever, and cough. Only six (43%) had bilateral sparse rales on auscultation. Arterial blood gas analysis at the onset of VZVP revealed hypoxemia in seven patients (50%) and hypocapnia in six (43%). Mean PaO(2) was 55 mmHg (range of 42-68 mmHg) and mean PaCO(2) was 34 mmHg (range of 27-36 mmHg). Chest radiographs showed ill-defined nodular or reticular densities of various sizes scattered throughout both lung fields. A CT scan of the chest, performed in seven patients (50%), confirmed the radiological findings and marked out patchy ground-glass attenuation in three patients and coalescence of lesions in two others. After diagnosis, all patients were immediately started on acyclovir 5-10 mg/kg every 8 h. Five patients (36%) were admitted to the ICU due to acute hypoxemic respiratory failure. Two patients received noninvasive positive pressure ventilation via a facemask and the other three patients with a clinical diagnosis of ARDS were intubated and ventilated mechanically. The duration of patient hospitalization was 16+/-10 days. One patient (8%) died in the ICU on the third day after admission due to multiple organ dysfunction (MOF). All of the other patients recovered completely without any sequelae. CONCLUSIONS: Adult patients with severe VZVP must be admitted and treated in the ICU. The use of intravenous acyclovir may be lifesaving, preventing progressive respiratory failure and reducing the high mortality rate of the disease.
