Abstract
A multicenter retrospective study in 131 patients (44 females/87 males) with hematological disorders who underwent G-CSF-primed/haplo-identical (Haplo-ID) (n = 76) or HLA-identical (HLA-ID) HSCT (n = 55) from February 2013 to February 2016 was conducted to compare the incidence and risk factors for pre-engraftment bloodstream infection (PE-BSI). In the Haplo-ID group, 71/76 patients with high-risk (n = 28) or relapsed/refractory hematological malignancies (n = 43) received FA5-BUCY conditioning (NCT02328950). All received trimethoprim–sulfamethoxazole (TMP–SMX) prophylaxis. Blood cultures and catheter tip cultures were obtained to confirm the BSI. PE-BSI was detected in 24/131 HSCT patients (18/76 in Haplo-ID and 6/55 in HLA-ID) after 28 febrile neutropenic episodes. Among 28 isolates for the 24 patients, 21 (75%) were Gneg bacteria, 6 (21.4%) Gpos and 1 (3.6%) fungi. Bacteria sources were central venous line infection (7/29.2%), gastroenteritis (6/25%), lower respiratory tract infection (LRTI; 5/20.8%), perianal skin infection (4/16.7%), and unknown (2/8.3%). The duration of neutropenia (P = 0.046) and previous Gneg bacteremia (P = 0.037) were important risk factors by univariate analysis, while the type of HSCT was not. A trend of TMP–SMX-resistant BSI in both groups may be due to routine antibacterial prophylaxis strategies. Our data show that G-CSF-primed Haplo-ID HSCT did not increase the risk of PE-BSI, even with intensive immunosuppressive treatments.
