Pattern of bacterial infections in neutropenic febrile patients (experience of the Specialized BMT center - Medical city complex - Baghdad, Iraq)

BACKGROUND: Infectious complications occur in most of the patients undergoing hemopietic stem cell transplantation (HSCT), these carry high risk of mortality mainly due to Gram-negative bacteria unless effective antibiotic treatment is provided. OBJECTIVES: The aims of the study were to review bacterial isolates from different samples in febrile neutropenic patients underwent HSCT in terms of incidence, types, and antimicrobial resistance, and to assess the efficacy of infection control measures used in transplantation ward. PATIENTS AND METHODS: This is retrospective study. The medical records of a total of 82 patients who underwent HSCT in the Specialized BMT Center, Baghdad Medical City, in 2021 and 2022 were reviewed; for any patient with neutropenic fever (NF), the clinical assessment was made, and samples were taken for culture any sensitivity before starting empirical antibiotics. The study was reviewed by the ethical committee of the hematology transplant center in the Medical City Complex, and since the study is retrospective, no consent is needed from the patient. RESULTS: There were 57 patients who developed NF, two at the time of collection, while 55 patients during transplant. In 16 patients, there was a clinical focus for NF, most commonly respiratory. From 175 samples sent for culture and sensitivity, bacterial growth was detected in 103 samples, and the incidence of bloodstream infection was 53%. Polymicrbial bacterial growth was detected in 6 patients with NF. Gram-positive bacteria were slightly more common than Gram negative. Staphylococcus epidermidis and Burkholderia cepacia were the most common Gram positive and Gram negative, respectively. An increasing number of patients admitted to transplant centers were associated with more infections. Ten out of 13 bacteria were multidrug resistant (MDR). Only two patients died from infection posttransplant. CONCLUSIONS: The predominance of Gram-positive cocci and Burkholderia cepacia complex supported the need to review the adherence to infection control policy. The empirical antibiotic protocol should be guided by local antibiogram, and since the high rate of blood stream infection (BSI) with MDR pathogens, a de-escalating strategy utilizing carbapenems – as advised by the ECIL-4 guidelines – would be more appropriate while awaiting culture result. The ability to quickly identify infections and their susceptibility profile is still crucial for choosing antibiotic therapy

Comprehensive global collaboration in the care of 1182 pediatric oncology patients over 12 years: The Iraqi–Italian experience

Abstract Background Iraq's health care system has gradually declined after several decades of wars, terrorism, and UN economic sanctions. The Oncology Unit at Children's Welfare Teaching Hospital (CWTH) in Baghdad was lacking basic facilities and support. To address this shortcoming, a humanitarian and educational partnership was established between CWTH and Sapienza University of Rome (SUR). Methods We investigated the outcomes of 80 online and 16 onsite educational sessions and 142 teleconsultation sessions from 2006 to 2014. We also determined the outcomes of pathology reviews by SUR of 1216 tissue specimens submitted by CWTH from 2007 until 2019 for second opinions. The primary outcomes were discordance, concordance, and changes among clinical diagnoses and pathology review findings. The measures included the frequency of teleconsultation and tele‐education sessions, the topics discussed in these sessions, and the number of pathology samples requiring second opinions. Findings A total of 500 cases were discussed via teleconsultations during the study period. The median patient age was 7 years (range, 24 days to 16·4 years), and the cases comprised 79 benign tumors, 299 leukemias, 120 lymphomas, and 97 solid tumors. The teleconsultation sessions yielded 27 diagnostic changes, 123 confirmed diagnoses, and 13 equivocal impacts. The pathology reviews by SUR were concordant for 996 (81·9%) cases, discordant for 186 (15·3%), and inconclusive for 34 (2·8%). The major cause of discordance was inadequate immunohistochemical staining. The percentage of discordance markedly decreased over time (from 40% to 10%). The cause of the improvement is multifactorial: training of two CWTH pathologists at SUR, better immunohistochemical staining, and the ongoing clinical and pathologic telemedicine activities. The partnership yielded 12 publications, six posters, and three oral presentations by CWTH investigators. Interpretation The exchange of knowledge and expertise across continental boundaries meaningfully improved the diagnoses and management of pediatric cancer at CWTH
