Role of granulocyte transfusions in invasive fusariosis: systematic review and single-center experience.

ABSTRACT: Invasive Fusarium infection is relatively refractory to available antifungal agents. Invasive fusariosis (IF) occurs almost exclusively in the setting of profound neutropenia and/or systemic corticosteroid use. Treatment guidelines for IF are not well established, including the role of granulocyte transfusions (GTs) to counter neutropenia.We conducted a systematic review, identifying IF cases where GTs were used as adjunctive therapy to antifungal agents and also report a single-center case series detailing our experience (1996-2012) of all IF cases treated with antifungal agents and GTs. In the systematic review cases, GTs were predominantly collected from nonstimulated donors whereas, in the case series, they were universally derived from dexamethasone- and granulocyte-colony-stimulating factor-stimulated donors.Twenty-three patients met inclusion criteria for the systematic review and 11 for the case series. Response rates after GTs were 30 and 91% in the review and case series, respectively. Survival to hospital discharge remained low at 30 and 45%, respectively. Ten patients in the systematic review and three in the case series failed to achieve hematopoietic recovery and none of these survived. In the case series, donor-stimulated GTs generated mean "same-day" neutrophil increments of 3.35 × 10(9) ?±?1.24 × 10(9) /L and mean overall posttransfusion neutrophil increments of 2.46 × 10(9) ?±?0.85 × 10(9) /L. Progressive decrements in neutrophil response to GTs in two cases were attributed to GT-related HLA alloimmunization.In patients with IF, donor-stimulated GTs may contribute to high response rates by effectively bridging periods of neutropenia or marrow suppression. However, their utility in the absence of neutrophil recovery remains questionable.

Project description:Background and Objectives: Cornual pregnancies (CPs) are rare forms of ectopic pregnancy. When abortion does not occur, it can be a life-threatening condition for the mother and can also impair future fertility. We present our experience in the diagnosis and management of CPs. A systematic review was also conducted to investigate the reproductive outcomes after treatment. Materials and Methods: Between January 2010 and December 2022, we performed a retrospective, cross-sectional, single-center, and descriptive data collection and analysis (ClinicalTrial ID: NCT06165770). The search for suitable articles published in English was carried out using the following databases (PROSPERO ID: CRD42023484909): MEDLINE, EMBASE, Global Health, The Cochrane Library (Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Cochrane Methodology Register), Health Technology Assessment Database, Web of Science, and search register such as ClinicalTrial. Only studies describing the impact of CP treatment on fertility were selected. Results: Two studies were included in the systematic review. Seventeen patients suffering from CPs were selected. In our series, a pelvic ultrasound allowed for the diagnosis of a cornual localization in 35.30% of cases. Thirteen women (76.47%) underwent immediate surgical management. The laparoscopic approach was the most used (76.92%), with a laparotomic conversion rate of 30%. Four patients (23.52%) received medical treatment with methotrexate. After treatment, two patients managed to achieve pregnancy. Conclusions: CP is a rare form of ectopic pregnancy that can quickly become life-threatening for the mother. Ultrasound does not lead to a precise diagnosis in all cases. In the absence of complications and emergencies, laparoscopy is an approach that could be considered valid. For selected asymptomatic patients, medical treatment may be a valid alternative. The data from the studies included in the systematic review, although demonstrating a superiority of medical treatment in terms of future pregnancies, are heterogeneous and do not allow us to reach a definitive conclusion.

Project description:BackgroundThe high rate of periprocedural complications for the endovascular stent procedure in the Stenting Versus Aggressive Medical Management Therapy for Intracranial Arterial Stenosis (SAMMPRIS) trial resulted in it being less recommended than medical therapy to treat intracranial atherosclerotic stenosis (ICAS). Because Enterprise stent use might reduce the incidence of complications in ICAS treatment compared to other frequently used stents, this paper evaluated the safety and effectiveness of the Enterprise stent for the treatment of ICAS.MethodsWe performed a comprehensive literature search for reports on intracranial angioplasty using the Enterprise stent for ICAS treatment from the earliest date available from each database to May 2020 for PubMed, EMBASE, Web of Science, Cochrane, and Clinical Trials databases. We also reviewed the single-center experience of the First Affiliated Hospital of Harbin Medical University. We extracted information regarding periprocedural complications, procedure-related morbidity, mortality, immediate angiographic outcome, and long-term clinical and angiographic outcomes, among others. Event rates were pooled across studies using random-effects or fixed-effects models depending on the heterogeneity.ResultsFive hundred fifty-seven patients with 588 lesions from seven studies, including the institutional series, were included in the analysis. The incidence of stroke or death within 30 days was 7.4% (95% confidence interval (CI), 5.5%-10.1%). The incidence of ischemic stroke or TIA in the territory of the qualifying artery beyond 30 days and during follow-up was 3.2% (95% CI, 1.1%-9.5%). The incidence of in-stent restenosis was 10.1% (95% CI, 4.6%-22.2%), and the incidence of symptomatic restenosis was 4.1% (95% CI, 1.7%-9.9%).ConclusionsIntracranial angioplasty utilizing the Enterprise stent for ICAS treatment was relatively safe and effective but required further verification using additional sources for evidence.
