Sumario: | OBJECTIVE: To explore the effects of peri-immunosuppressive treatment (IST) infection on outcomes of severe and very severe aplastic anemia (SAA/VSAA) patients. METHODS: Medical record and follow-up data of 105 SAA/VSAA who underwent first-line IST were retrospectively analyzed to find out the characters of infections (1 month before to 3 months after IST), and its effects on hematologic response and survival. RESULTS: Of 105 patients, a total of 270 febrile episodes were recorded in 97 patients (92.4%) during their peri-IST periods, with the median infections of 2 (1–7) episodes in each patient with the median febrile duration of 7 (1–47) days. Respiratory system (35.1%) was the primary anatomic site of infection. Bacteria (88.2%) were common causes of total 169 pathogenic bacteria in 96 clear pathogenic bacteria episodes. And patients who got infection 1 month before IST had much lower 6-month hematologic response rate than their counterpart ones (50.8% vs 80.0%, P=0.004). Multiple febrile episodes (≥3 times) and the total febrile duration ≥4 days showed the best sensitivity and specificity according to the ROC curve analysis. The 5-year overall survival of the 105 patients was 76%. The 5-year OS of patients with multiple febrile episodes (≥3 times) were much lower than their counterpart ones [(59.6±7.2)% vs (89.5±4.0)%] (P <0.01). The 5-year OS of the total febrile duration ≥ 4 days was much lower than their counterpart ones [(63.4±5.8)% vs 100.0%] (P<0.01). CONCLUSION: Infections 1 month before IST were associated with hematologic response. Multiple febrile episodes (≥3 times) and infections with the febrile duration ≥4 days presented inferior hematologic response and survival. |
