Clinical Characteristics and Outcome of Invasive Mould Sinusitis in
Children with Hematological Malignancies
Abstract
Background: Pediatric patients with hematologic malignancies are
susceptible to invasive mould sinusitis (IMS). IMS is a rare entity that
requires careful attention and prompts management due to its high
mortality. Methods: This is a retrospective analysis of pediatric
patients with hematological malignancies treated at Children Cancer
Hospital Egypt through the period from 2008 till 2016 with proven IMS.
Results: Thirty-four patients were diagnosed with IMS. Five 5(15%)
patients had an invasive rhino-cerebral fungal disease. Mucormycosis
were isolated in 17(50%) patients, Aspergillosis in 13 (38%) patients,
and mixed fungal in 4 (12%) patients. Sinuses were the only localized
site in (45%). Extra-nasal spread was reported in 20 patients;
Sino-pulmonary in 12(35%), Sino-cerebral in 5(15%), and Sino-orbital
in 2(5%) patients. Combined antifungal therapy with surgical
debridement was done in 59% of patients with a better outcome when
compared to those who received only medical antifungal treatment (P =
0.01). The overall mortality rate at week 12 was 35% (12 patients), and
IMS attributable mortality was 20% (7 patients). IMS with cerebral
extension carried the highest mortality rate for both 12-week all-cause
(p=0.04) and fungal-attributable (P=0.01) mortality. Conclusions:
Pediatric patients with hematologic malignancies are susceptible to
invasive mould sinusitis (IMS). Surgical debridement, combined with
antifungal therapy, improves outcomes among those patients. IMS patients
with cerebral extension had a higher risk of mortality.
