Common variable immunodeficiency (CVID) is the most frequent clinically manifested primary immunodeficiency. According to clinical and laboratory findings, CVID is a heterogeneous group of diseases. Recently, the defects of molecules regulating activation and terminal differentiation of B lymphocytes have been described in some patients with CVID. In this study, we show the overview of deficien...

pyoderma vegetans (pv) is a rare inflammatory disorder characterized by vegetating pustules and plaques affecting the skin and mucosal membranes. it is believed that this entity is mostly associated with inflammatory bowel disease (ibd), chronic malnutrition, human immunodeficiency virus (hiv), malignancies, and other immunocompromised states. pyoderma vegetans occurs more commonly in young and...

Primary immunodeficiency disorders (PIDs) are rare genetic diseases of the immune system. With improving awareness of PIDs among clinicians, the number of patients diagnosed with PIDs is rising rapidly in Southeast Asia. However, delayed diagnosis remains common and adversely affects the prognosis of these patients. In this review, we provide simple phenotypic approach to the diagnosis of PIDs ...

Our understanding of immunity has historically been informed by studying heritable mutations in both the adaptive and innate immune responses, including primary immunodeficiency and autoimmune diseases. Recent advances achieved through the application of genomic and epigenomic approaches are reshaping the study of immune dysfunction and opening up new avenues for therapeutic interventions. More...

Although relatively rare, primary immunodeficiency diseases (PIDs) provide an excellent window into the functioning of the immune system. In the late 1960s, observations on these diseases, with their associated infections and genetics, bisected the immune system into humoral immunity and cell-mediated immunity. These diseases also represent a challenge in their diagnosis and treatment. Beginnin...
