A late preterm infant with intrauterine growth restriction developed respiratory distress, tachypnoea and hypoxia after birth, requiring supplemental oxygen. Chest radiographs demonstrated persistent elevation of the right hemidiaphragm. Chest ultrasound initially demonstrated symmetrical bilateral diaphragm motion, but subsequent ultrasounds showed asymmetrical excursion with weaker movement of the right hemidiaphragm. Placental pathology demonstrated chronic infectious villitis secondary to cytomegalovirus (CMV), and subsequent CMV testing on the infant was positive. The infant was microcephalic and head imaging revealed intracranial calcifications, consistent with congenital CMV infection.CMV is the most common congenital infection and has a wide array of clinical manifestations. This report highlights the rarely described association between congenital CMV infection and respiratory distress due to underlying diaphragm dysfunction. In neonates with respiratory distress and features of congenital CMV infection, clinicians should have a high index of suspicion for diaphragm dysfunction.

Kikuchi-Fujimoto disease (KFD) is a rare, self-limiting condition typically characterized by fever and lymphadenopathy. The exact etiology remains unclear but is suspected to be associated with viral infections and autoimmune responses. This report presents the case of a 32-year-old Chinese male who was admitted with recurrent high fever, lymphadenopathy, and hepatosplenomegaly.

Purpose: This study aimed to investigate the impact of herpesvirus detection by metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid (BALF) on lower respiratory tract infections (LRTIs) patients' lung microbiome composition and prognosis.
Patients And Methods: We initially enrolled 234 hospitalized patients with LRTIs who underwent BALF mNGS between February 2022 and May 2023. The study analyzed the clinical manifestations and the pulmonary microbial composition between herpesvirus detection (HD) and non-herpesvirus detection (non-HD) group.

Background: In vivo T-cell depletion with antithymocyte globulin (ATG), especially at high-doses has been shown to be associated with increased incidence of infections after allogeneic hematopoietic stem cell transplantation (HSCT). However, it remains unclear whether ATG, even at low-doses increases the risk of posttransplant infections in the high-risk HSCT setting.
Patients And Methods: We conducted a single-center retrospective study of viral and fungal infections early after transplantation, using the data from 82 patients with hematological malignancies.

Cytomegalovirus (CMV) infection remains one of the most common and challenging post-transplant infections. Children with inborn errors of immunity (IEI) and T-cell dysfunction are at high risk for CMV infection, which can be complicated by refractory and/or resistant cases. This case describes a Nepalese girl with MHC class II deficiency, who presented at 3 months of age with CMV and Pneumocystis jirovecii pneumonia.

In this narrative review, we explore the burden and risk factors of various herpesvirus infections in patients receiving chimeric antigen receptor T-cell (CAR-T) therapy or bispecific antibodies (BsAb) for the treatment of hematologic malignancies. Antiviral prophylaxis for herpes simplex/varicella zoster viruses became part of the standard of care in this patient population. Breakthrough infections may rarely occur, and the optimal duration of prophylaxis as well as the timing of recombinant zoster immunization remain to be explored.
