Background: WHIM syndrome corresponds to an inborn error of innate and intrinsic immunity, characterized by: warts (Warts), Hypogammaglobulinemia, Infections and Myelocathexis, for its acronym in English.
Case Report: 4-year-old male, with severe neutropenia and B-cell lymphopenia from birth, without severe infections or warts; the panel genetic sequencing study of primary immunodeficiencies with the CXCR4 c.1000C>T (p.Arg334*) variant, which is associated with WHIM syndrome.
Conclusions: The diagnosis of severe neutropenia from birth should include the search for inborn errors of immunity, through genetic sequencing studies, especially in asymptomatic or oligosymptomatic patients.

Clinical characteristics and prognosis of patients treated as invasive pulmonary aspergillosis outside of severe immunosuppression.
Sci Rep
January 2025
Department of Critical Care Medicine, General Hospital of Ningxia Medical University, Yinchuan, 750004, China.
This study aimed to identify clinical characteristics and develop a prognostic model for non-neutropenic patients with invasive pulmonary aspergillosis (IPA). A retrospective analysis of 151 IPA patients was conducted, with patients categorized into survival (n = 117) and death (n = 34) groups. Clinical data, including demographics, laboratory tests, and imaging, were collected.

This study investigated the correlation between quantitative echocardiographic characteristics within 3 days of birth and necrotizing enterocolitis (NEC) and its severity in preterm infants. A retrospective study was conducted on 168 preterm infants with a gestational age of < 34 weeks. Patients were categorized into NEC and non-NEC groups.

Background: Severe fever with thrombocytopenia syndrome (SFTS) is an emerging infectious disease characterized by leukopenia and thrombocytopenia, and aspergillosis is a common complication in severe cases. Previous studies have reported cases of SFTS complicated with invasive pulmonary aspergillosis (IPA) and central nervous system aspergillosis. Here, we present the first case of an immunocompetent patient with SFTS who progressed to IPA and Aspergillus endocarditis after glucocorticoid treatment, and embolism of the vegetations from the left ventricle led to multiple infarctions in the brain, kidney, and spleen.

Systemic lupus erythematosus (SLE) is an inflammatory autoimmune disease with an important course due to systemic compromise. SLE is frequently associated with antiphospholipid syndrome, and pulmonary thromboembolism (PE) is particularly common. It is extremely rare for PE to be the initial clinical presentation and even more uncommon for it to coincide with cardiac tamponade, representing a challenge in diagnosis and management.
