Abstract
The emergence of vaccine-derived polioviruses (VDPVs) in patients with Primary Immunodeficiency (PID) is a threat to the polio-eradication program. In a first of its kind pilot study for successful screening and identification of VDPV excretion among patients with PID in India, enteroviruses were assessed in stool specimens of 154 PID patients across India in a period of two years. A total of 21.42% of patients were tested positive for enteroviruses, 2.59% tested positive for polioviruses (PV), whereas 18.83% of patients were positive for non-polio enteroviruses (NPEV). A male child of 3 years and 6 months of age diagnosed with Hyper IgM syndrome was detected positive for type1 VDPV (iVDPV1) with 1.6% nucleotide divergence from the parent Sabin strain. E21 (19.4%), E14 (9%), E11 (9%), E16 (7.5%), and CVA2 (7.5%) were the five most frequently observed NPEV types in PID patients. Patients with combined immunodeficiency were at a higher risk for enterovirus infection as compared to antibody deficiency. The high susceptibility of PID patients to enterovirus infection emphasizes the need for enhanced surveillance of these patients until the use of OPV is stopped. The expansion of PID surveillance and integration with a national program will facilitate early detection and follow-up of iVDPV excretion to mitigate the risk for iVDPV spread.

Abstract
Introduction: The transcription factor IKAROS and IKAROS family members are critical for the development of lymphocyte and other blood cell lineages. Germline heterozygous IKZF1 mutations have been described in primary immunodeficiency as well as in human hematologic malignancies, affecting both B and T cells. Depending on the allelic variants of IKZF1 mutations (haploinsufficiency and dominant negative) clinical phenotypes vary from bacterial, viral, or fungal infection to autoimmune disease and malignancy.Areas covered: In this review, the authors provide an overview of genotype-phenotype correlation and clinical manifestations in patients with IKZF1 mutations. The importance of accurate diagnosis and monitoring immunological changes is also discussed for the management of these complex and rare diseases. IKZF1/IKAROS, immunodeficiency, and CVID were used as the search terms in PubMed and Google Scholar.Expert opinion: Over the past 5 years both genetic and molecular studies have unveiled surprisingly diverse roles of IKZF1 mutations in primary immunodeficiency. While an increasing number of novel IKZF1 variants are being reported, limited, and complex laboratory testing is necessary to verify the mutation's pathogenicity. Therefore, the combination of understanding mechanistic concepts and clinical and immunological follow-up is necessary to increase our knowledge of IKAROS-associated diseases.

Abstract
IKAROS, encoded by IKZF1, is a zinc finger transcription factor and a critical regulator of hematopoiesis. Mutations in IKZF1 have been implicated in immune deficiency, autoimmunity, and malignancy in humans. Somatic IKZF1 loss-of-function mutations and deletions have been shown to increase predisposition to the development of B cell acute lymphoblastic leukemia (B-ALL) and associated with poor prognosis. In the last 4 years, germline heterozygous IKZF1 mutations have been reported in primary immune deficiency/inborn errors of immunity. These allelic variants, acting by either haploinsufficiency or dominant negative mechanisms affecting particular functions of IKAROS, are associated with common variable immunodeficiency, combined immunodeficiency, or primarily hematologic phenotypes in affected patients. In this review, we provide an overview of genetic, clinical, and immunological manifestations in patients with IKZF1 mutations, and the molecular and cellular mechanisms that contribute to their disease as a consequence of IKAROS dysfunction.
