RESUMEN
<p><b>OBJECTIVE</b>To study the changes of peripheral blood chromosomal centromere aberration in patents with cytomegalovirus (CMV) infection after anti-viral treatment.</p><p><b>METHODS</b>Sixty-two patients with early spontaneous abortion and CMV infection analyzed for their peripheral blood chromosomal centromere using simultaneous silver staining before and after anti-viral treatment.</p><p><b>RESULTS</b>The patients with CMV infection had high rate of centromere aberration, which was decreased significantly after anti-viral treatment (P<0.0001).</p><p><b>CONCLUSION</b>CMV infection is a risk factor for peripheral blood chromosomal centrimere aberration. Anti-viral treatment can decrease the rate of centrimere aberration aberration. Detection of peripheral blood chromosomal centrimere aberration allows the assessment of the severity of infection and the condition after treatment.</p>
