Clinical and molecular profile of 20 patients with DOCK8 deficiency-a single-center experience from Southern India.

DOCK8 deficiency is the most common cause of autosomal recessive hyper-IgE syndrome (AR-HIES). The clinical spectrum is wide resulting in combined immunodeficiency, atopy, autoimmunity, and malignancies. To study the clinical and molecular profile of 20 patients with DOCK8 deficiency.

Electrospray triple quadrupole mass spectrometry guides pathologists to suggest appropriate molecular testing in the identification of rare hemoglobin variants.

Background: The presumptive diagnosis of hemoglobinopathies relies on routine tests such as Complete Blood Count (CBC), peripheral blood smear, Liquid Chromatography (LC), and Capillary Electrophoresis (CE), along with clinical findings. Pathologists suggest molecular sequencing of HBA and HBB genes to correlate blood picture with clinical findings in order to identify unknown rare haemoglobin (Hb) variants or variants that coelute with Hb. This paper presents a low-resolution mass spectrometry (MS)-based method for presumptive identification of variants that eluted in zone 12 of CE, followed by molecular sequencing of the HBB gene for a definitive diagnosis of hemoglobinopathies.

Clinical, Immunological, and Molecular Profile of Chronic Granulomatous Disease: A Multi-Centric Study of 236 Patients From India.

Background: Chronic granulomatous disease (CGD) is an inherited defect in phagocytic respiratory burst that results in severe and life-threatening infections in affected children. Single center studies from India have shown that proportion of autosomal recessive (AR) CGD is more than that reported from the West. Further, affected patients have high mortality rates due to late referrals and difficulties in accessing appropriate treatment.

Clinical, Immunological, and Molecular Features of Severe Combined Immune Deficiency: A Multi-Institutional Experience From India.

Background: Severe Combined Immune Deficiency (SCID) is an inherited defect in lymphocyte development and function that results in life-threatening opportunistic infections in early infancy. Data on SCID from developing countries are scarce.

Objective: To describe clinical and laboratory features of SCID diagnosed at immunology centers across India.

Clinical and Genetic Profile of X-Linked Agammaglobulinemia: A Multicenter Experience From India.

Background: There is paucity of literature on XLA from developing countries. Herein we report the clinical and molecular profile and outcome in a multicenter cohort of patients with XLA from India.

Methods: Data on XLA from all regional centers supported by the Foundation for Primary Immunodeficiency Diseases (FPID), USA and other institutions providing care to patients with PIDs were collated.

Clinical and Genetic Spectrum of a Large Cohort of Patients With Leukocyte Adhesion Deficiency Type 1 and 3: A Multicentric Study From India.

Leukocyte adhesion deficiency (LAD) syndrome is a group of inborn errors of immunity characterized by a defect in the cascade of the activation and adhesion leading to the failure of leukocyte to migrate to the site of tissue injury. Three different types of LAD have been described. The most common subtype is LAD type 1 (LAD1) caused due to defects in the gene.

Anastomosing hemangioma with extensive fatty stroma in the retroperitoneum.

Anastomosing hemangiomas are a recently recognized benign vascular neoplasm, first described by Montgomery and Epstein in 2009. A few cases have been described in the genitourinary tract, especially in the renal hilum. These are fairly well-demarcated lesions with lobules of sinusoidal-like capillaries lined by hobnail endothelial cells containing eosinophilic hyaline globules in the cytoplasm.
