Infección asociada a catéter central por Cryptococcus laurentii en niño críticamente enfermo: a propósito de un caso y revisión del tema

Abstract

Cryptococcosis is a fungal infection that predominantly affects patients with compromised cellular immunity. Cryptococcus neoformans is the most common pathogen of this class. Endovascular catheter-related infection is a rare entity described for Cryptococcus laurentii and, in exceptional cases, for C. neoformans. A case of a 3-month-old child with adenovirus acute bronchiolitis which lead to respiratory failure requiring inotropy and developing multiple infectious complications is presented. Cryptococcus laurentii was isolated in the culture from the tip of the central catheter, which could not be obtained in blood cultures. He was treated with amphotericin B in a cumulative dose of 10 mg/kg with negative control cultures. From a respiratory point of view, evolution was not good, with a failure from mechanical ventilation and posterior death.
