Childhood herpes simplex virus-1 (HSV-1) encephalitis (HSE) may result from single-gene inborn errors of TLR3 immunity. TLR3-dependent induction of IFN-α/β or IFN-λ is crucial for protective immunity against primary HSV-1 infection in the central nervous system (CNS). We describe here two unrelated children with HSE carrying different heterozygous mutations(More)
Chronic granulomatous disease (CGD) is a rare primary immunodeficiency caused by a defect of phagocyte NADPH-oxidase and characterized by severe, recurrent bacterial and fungal infections. Invasive aspergillosis (IA) is the leading cause of mortality in patients with CGD. We report the case of a 3-year-old boy with CGD, who developed IA despite antifungal(More)
Common variable immune deficiency (CVID) is a heterogeneous disease associated with ineffective production of antibodies. It is usually diagnosed in adulthood, but a variable proportion of children develop CVID. Early identification of patients with potentially worse prognosis may help to avoid serious complications. The goal of this study was to associate(More)
Nijmegen Breakage Syndrome (NBS) is a rare inherited condition, characterized by microcephaly, chromosomal instability, immunodeficiency, and predisposition to malignancy. This retrospective study, characterizing the clinical and immunological status of patients with NBS at time of diagnosis, was designed to assess whether any parameters were useful in(More)
Griscelli syndrome type 2 (GS2) is a rare autosomal-recessive disorder associated with a RAB27A gene mutation, and clinically manifesting as hypopigmentation, disseminated chronic encephalitis, and severe immunological disorders characterized by an accelerated hematological phase, also referred to as hemophagocytic syndrome (HS), or hemophagocytic(More)
BACKGROUND AND OBJECTIVE Giant cell hepatitis (GCH) with autoimmune hemolytic anemia (AIHA) is a rare, progressive disorder in infants and young children. The disease is aggressive and may lead to liver or multiorgan failure with fatal prognosis. Therapy with anti-CD20 monoclonal antibody, rituximab (Rtx), proved effective. The primary objective of the(More)
UNLABELLED Chronic neutropenia (CN) is defined by an absolute neutrophil count (ANC) below 1500/ul, lasting at least 6 months. AIM clinical course and treatment of children afflicted with CN was analysed. MATERIAL AND METHODS we present 60 children treated in our department due to CN. The diagnosis was based on: bone marrow smears, ANC, immunologic(More)
Combined vaccines are urgently needed because of the increasing number of recommended vaccines for children. Combined vaccines could be considered as having the same priming effect as monovalent vaccines. They demonstrated a good reactogenicity and tolerability profile. Combined vaccines are more comfortable option for the infant vaccination providing(More)
