Review of Herpes Zoster Occurrence in Patients With Atopic Dermatitis Treated With JAK Inhibitors

Clinical and Translational Science, Volume 19, Issue 3, March 2026.
ABSTRACT Atopic dermatitis (AD) is a chronic inflammatory skin disease that markedly impairs quality of life. Janus kinase inhibitors (upadacitinib, abrocitinib, and baricitinib) are effective therapies for moderate‐to‐severe AD but are associated with viral reactivation, particularly herpes zoster (HZ), due to immunosuppressive effects on interferon ...

Mechanisms of Surface Antigenic Variation in the Human Pathogenic Fungus Pneumocystis jirovecii. [PDF]

, 2017
Microbial pathogens commonly escape the human immune system by varying surface proteins. We investigated the mechanisms used for that purpose by <i>Pneumocystis jirovecii</i> This uncultivable fungus is an obligate pulmonary pathogen that ...

Infections in Chronic Lymphocytic Leukemia: Evolving Risks and Prevention Strategies

European Journal of Haematology, Volume 116, Issue 3, Page 204-214, March 2026.
ABSTRACT Infections remain a leading cause of morbidity and mortality in patients with chronic lymphocytic leukemia (CLL), reflecting both intrinsic immune dysfunction and therapy‐related immunosuppression. The pathogenesis of immunodeficiency in CLL is multifactorial: neoplastic B cells impair humoral immunity, T cells are functionally exhausted, and ...

Late diagnosis of paediatric HIV infection in high‐income countries: Lessons from the HIV Perinatal Virtual Clinic

HIV Medicine, Volume 27, Issue 3, Page 477-484, March 2026.
Abstract Introduction Timely diagnosis of HIV in children remains a challenge in all settings including low‐prevalence, high‐income countries (HIC). We aimed to characterize the prevalence of late diagnosis, and prior missed diagnostic opportunities among new presentations of paediatric HIV in HIC referred to an international Perinatal Virtual Clinic ...

Incidence of RSV‐ and Influenza‐Associated Hospitalizations With Community‐Acquired Pneumonia and Other Acute Respiratory Infection Among Adults in Japan in 2022–2024: APSG‐J2 Study

Influenza and Other Respiratory Viruses, Volume 20, Issue 3, March 2026.
ABSTRACT Background Quantifying the burden of respiratory syncytial virus (RSV) in adults is challenging compared to influenza, and data among older adults remain scarce in Japan. Country‐specific evidence is essential to support RSV vaccination policy.

Colonization by Pneumocystis jirovecii in patients with chronic obstructive pulmonary disease: association with exacerbations and lung function status

Brazilian Journal of Infectious Diseases, 2019
Exposure to Pneumocystis jirovecii (P. jirovecii) can lead to a wide variety of presenting features ranging from colonization in immunocompetent patients with lung disease, to invasive infections in immunocompromised hosts. Colonization by this fungus in
