[Varicella pneumonia during pregnancy after double exposure in the 2nd trimester. Value of seroprophylaxis].

We report on a case of varicella pneumonia at 29 weeks of gestation after double contact during the second trimester of pregnancy although passive immunotherapy by polyvalent immunoglobulins was used. Our case report highlights the difficulties of varicella pneumonia diagnosis that was here confirmed by seroconversion and the presence of pathognomonic microcalcifications, on a pulmonary X-ray, realized two years after pregnancy. Although the absence of publications asserting the efficacy of immunotherapy by polyvalent immunoglobulins to prevent maternal complications of varicella during pregnancy, they remain widely employed in such cases. Our point of view is that this indication must be revisited.
