Abstract
Anorectal infections in neutropenic leukemia patients are a significant and potentially life-threatening complication. The pathogenesis of this condition is not entirely understood and believed to be multifactorial, including mucosal injury as a result of cytotoxic drugs, profound neutropenia and impaired host defense. Establishing an early diagnosis is key and often made clinically on the basis of signs and symptoms, but also from imaging studies demonstrating perianal inflammation or fluid collection. The management of anorectal infections in neutropenic leukemia patients is not straightforward, as there are no well-conducted studies on this entity. This review seeks to provide a framework into the pathophysiology and clinical presentation of anorectal infections in neutropenic leukemia patients, propose a diagnostic approach and to discuss controversies in the management of this condition.

Risk Factors for Neutropenic Sepsis Related Mortality in Children Undergoing Allogenic Hematopoietic Stem Cell Transplantation. Indian J Hematol Blood Transfus 2023; 39:1-6. [PMID: 36699434 PMCID: PMC9868024 DOI: 10.1007/s12288-021-01486-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/29/2021] [Accepted: 08/19/2021] [Indexed: 01/28/2023] Open
Abstract
We aimed to analyze infections in children undergoing hematopoietic stem cell transplantation (HSCT) until engraftment. The spectrum and risk factors associated will help plan interventions to reduce mortality. We performed a retrospective analysis on the infections, associated risk factors, and mortality until engraftment in children up to 18 years of age undergoing HSCT from January 2017 to August 2020. A total of 399 children were included, with a male: female ratio of 1.9:1, with matched related donor HSCT in 36.6%, a matched unrelated donor in 18.3%, and haploidentical HSCT in 38.1% of children. Culture positive bacteremia was documented in 22.1% transplants with gram-negative bacteria (GNB) isolated in 71/88 (80%). Among the GNB, the predominant organism was Klebsiella pneumonia in 38 (53%), E.coli in 16 (22%), Pseudomonas in 9 (12%). Carbapenem resistance was documented in 24/71 (33%). The incidence of possible, probable, and proven fungal infections in the cohort was 63 (15%), 28 (7%), and 6 (1.5%), respectively. Mortality up to engraftment due to sepsis in our cohort is 3.3% (n = 13). There was a significant association between mortality and a perianal focus (30.8%, p value 0.029) and the presence of carbapenem resistance (38%, p value 0.002). Mortality among those who developed proven fungal infections was significantly higher than those with bacteremia (p value 0.004). Our study has identified fungal sepsis and carbapenem-resistant GNB sepsis as high-risk groups for mortality. Risk directed interventions in these groups would help ensure survival and optimal outcomes.
