Cytokine Profile of Invasive Pulmonary Aspergillosis in Severe COVID-19 and Possible Therapeutic Targets.

Diagnostics (Basel) 2022 Jun 1;12(6). Epub 2022 Jun 1.

Infectious and Tropical Disease Unit, Department of Medical and Surgical Sciences, "Magna Graecia" University of Catanzaro, Viale Europa, 88100 Catanzaro, Italy.

During the SARS-CoV-2 pandemic, a higher incidence of invasive pulmonary aspergillosis was observed in patients affected by Coronavirus disease 2019 (COVID-19), leading to the delineation of a new entity named COVID-19 associated pulmonary aspergillosis (CAPA). A predisposition to invasive infection caused by spp. in SARS-CoV-2 infected patients can be ascribed either to the direct viral-mediated damage of the respiratory epithelium, as already observed in influenza H1N1 virus infections, or to the dysregulated immunity associated with COVID-19.

J Fungi (Basel) 2022 May 25;8(6). Epub 2022 May 25.

Infectious Diseases Service, Beaumont Hospital, D09 V2N0 Dublin, Ireland.

This case highlights the use of (1,3)-beta-d glucan to direct treatment of a cervical spinal cord infection in a 22-year-old woman immunocompromised due to steroid and anti-TNF therapy in the context of ulcerative colitis and interferon gamma deficiency. A 4-year treatment course requiring neurosurgical intervention on four occasions and prolonged antifungal therapy, including isavuconazole, resulted in clinical cure with a corresponding decrease in CSF beta-d-glucan to <30 pg/mL.

[Evaluation dosing intravenous voriconazole three times a day vs twice daily for the treatment of invasive aspergillosis in immunocompromised children: therapeutic drugs monitoring and safety].

Rev Chilena Infectol 2022 02;39(1):14-19

Unidad de Farmacia, Hospital Luis Calvo Mackenna, Santiago, Brasil.

Background: Voriconazole is the antifungal of choice for the treatment of invasive aspergillosis (IA). Plasma concentrations (PCs) > 1 μg / mL llave been associated with better therapeutic results which have not always been achieved during treatment in immunocompromised children. In the necessity to initiate early and effective therapy for the infection, it is relevant to establish the voriconazole administration regimen that is associated with optimal PCs in this population.

Clearance of atypical cutaneous manifestations of hyper-IgE syndrome with dupilumab.

Pediatr Dermatol 2022 Jun 22. Epub 2022 Jun 22.

Department of Dermatology, School of Medicine and Public Health, University of Wisconsin-Madison, Madison, Wisconsin, USA.

Hyper-IgE syndromes (HIES) are a heterogeneous group of rare primary immunodeficiency diseases classically characterized by the triad of atopic dermatitis, and recurrent cutaneous and pulmonary infections. Autosomal dominant, loss-of-function STAT3 pathogenic variants are the most common genetic cause, which lead to deficiency of Th17 lymphocytes, impaired interferon gamma production, and IL-10 signal transduction, and an unbalanced IL-4 state. Dupilumab, a monoclonal antibody to the IL-4a receptor, inhibits both IL-4 and IL-13, and has been shown to improve atopic dermatitis and other manifestations of HIES including asthma and allergic bronchopulmonary aspergillosis.

Neutrophil-Specific Knockdown of β2 Integrins Impairs Antifungal Effector Functions and Aggravates the Course of Invasive Pulmonal Aspergillosis.

Front Immunol 2022 6;13:823121. Epub 2022 Jun 6.

Department of Hematology, Medical Oncology and Pneumology, University Medical Center of the Johannes Gutenberg University, Mainz, Germany.

β2-integrins are heterodimeric surface receptors that are expressed specifically by leukocytes and consist of a variable α (CD11a-d) and a common β-subunit (CD18). Functional impairment of CD18, which causes leukocyte adhesion deficiency type-1 results in an immunocompromised state characterized by severe infections, such as invasive pulmonary aspergillosis (IPA). The underlying immune defects have largely been attributed to an impaired migratory and phagocytic activity of polymorphonuclear granulocytes (PMN). Read More
