A Study on the Efficacy of Empirical Antibiotic Therapy for Splenectomized Children with Fever.

Abstract

Thalassemia represents a heterogeneous group of inherited diseases characterized by the lack or reduced production of hemoglobin β-chains. Many patients with thalassemia require splenectomy. What should be considered in the evaluation and management of candidates for splenectomy is to cover vaccination against infections such as pneumococci and the implementation of antibiotic prophylaxis. This study aimed to investigate the effect of the antibiotic type on the outcome of acute post-splenectomy infection in patients with thalassemia.This investigation is a retrospective cohort study. One hundred fifty medical records of hemoglobinopathy patients who underwent splenectomy were collected from the Ali-Asghar Hospital, Tehran, Iran. SPSS v. 20 and SAS v. 1.9 were used to analyze the data.A total of 150 patients that were vaccinated against post-splenectomy infections and were under antibiotic prophylaxis underwent splenectomy. The most commonly prescribed drugs were ceftriaxone or cefotaxime (132 cases, 88%), followed by ceftriaxone plus clindamycin (5.3%), ceftriaxone plus amikacin (3.3%), clindamycin (1.3%), vancomycin plus amikacin (0.7%), and others (1.3%). In terms of treatment outcomes, 143 cases (95.3%) were treated with the same antibiotics, and 4 (2.7%) experienced a changed antibiotic regimen with vancomycin.The results show that perceptions of treatment for fever in splenectomized children need to be changed, and most of them do not require hospitalization and initiation of broad-spectrum antibiotics such as vancomycin for initially refractory cases, and can only be treated with daily intravenous ceftriaxone.
