Purpose: Wiskott-Aldrich syndrome (WAS) is an X-linked genetic disorder characterized by distinctive features including microthrombocytopenia, eczema and recurrent infections. In the present study we report clinical, immunological and molecular spectrum of 41 WAS patients diagnosed over last five years.
Methods: Clinical and family history was collected from case records.
DOCK8 deficiency affects various cell subsets belonging to both the innate and adaptive immune systems. Clinical diagnosis is challenging, as many cases present with severe atopic dermatitis as the only initial manifestation. Though flow cytometry helps in the presumptive diagnosis of DOCK8-deficient patients by evaluating their DOCK8 protein expression, it requires subsequent confirmation by molecular genetic analysis.

Non-infectious GI manifestations such as allergic, autoimmune, and inflammatory disorders can be the predominant manifestations of PIDs. We present a series of five children who presented predominantly with these GI manifestations of PID, not attributable to infections.

CARMIL2 deficiency is a recently described combined immunodeficiency (CID) disorder characterized by defective CD28-mediated T cell co-stimulation, altered cytoskeletal dynamics, susceptibility to various infections and Epstein Barr Virus smooth muscle tumor (EBV-SMT). We report a homozygous CARMIL2 pathogenic variant presenting with recurrent infections and EBV associated smooth muscle tumor (SMT) in a child.

HLH is classified as familial (FHL) when associated with mutations in , and genes. There is limited information available about the clinical and mutational spectrum of FHL patients in Indian population.

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.

Lymphoproliferative disorders occurs due to uncontrolled proliferation of lymphocytes that causes lymphocytosis, lymphadenopathy, and involvement of extra nodal sites (bone marrow, liver and spleen) and occur primarily due to immune dysfunction. We describe series of cases with non malignant LPD encountered in our practice and their varied clinical presentation, difficulties in diagnosis, underlying etiology, treatment and outcome. Many of these disorders are self limiting, however some are associated with significant morbidity, hence treatment must be tailored based on the underlying immune dysfunction and aggressiveness of the clone.

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

Methods: A retrospective analysis of case records of 52 children diagnossed with HLH was performed.
Results: Of the 52 children 13% (n = 7) had Familial HLH and 87% (n = 45) had secondary HLH (sHLH).

We present our experience in haploidentical stem cell transplantation (haplo SCT) in children with benign disorders. We performed a retrospective study where children aged up to 18 years diagnosed to have benign disorders and underwent haplo SCT from 2002 to September 2017 were included. Of the 54 children, the most common indications were Fanconi anaemia 12 (22%), severe aplastic anaemia 8 (14%) and primary immune deficiency disorders (PID) 25 (46%).

We present our experience and the challenges faced in the management of a 7-year-old boy with relapsed isolated extraocular retinoblastoma in the right fibula who received salvage chemotherapy followed by high-dose chemotherapy and autologous stem cell rescue. Electrolyte disturbances, renal tubulopathy, and seizures were the most significant transplant-related morbidity.

Haploidentical stem cell transplantation (haplo SCT) has emerged as an acceptable alternative to matched family donor transplantation for children diagnosed to have primary immune deficiency disorders (PIDs). We present data over 4 years on the challenges and efficacy of unmanipulated T cell replete haplo SCTs with post-transplant cyclophosphamide (PTCy) in children diagnosed to have PIDs. We performed a retrospective study in the pediatric blood and marrow transplantation unit where all children less than 18 years of age diagnosed to have PIDs and who underwent haplo SCT with PTCy from January 2014 to February 2018 were included in the study.

Transfusion-transmitted hepatitis C is a major concern among thalassemia patients. Our aim is to estimate the prevalence of Hepatitis C infection among thalassemia patients and to assess the treatment response, adverse effects of Peg-interferon based regimen and the new direct-acting antiviral drugs. Patients with thalassemia receiving regular blood transfusions with positive anti HCV antibodies during a period from January 2012 to June 2017 were analyzed.

Peg-asparaginase has widely replaced the use of conventional asparaginase in treatment of children with acute lymphoblastic leukaemia in developed countries. In developing countries like India, with financial constraints being a part of clinical challenge to the treatment of cancers, uniform use of Peg-asparaginase in all children is not practically possible. However, we found by a retrospective analysis of 211 children treated for acute lymphoblastic leukaemia, uniform use of this drug was feasible with indigenous techniques like storing the drug with strict cold chain maintenance and sharing the drug amongst 2 or 3 patients to reduce the burden on each family.
