Hereditary folate malabsorption is a rare inborn error of metabolism due to mutations in the proton-coupled folate transporter (PCFT). Clinical presentation of PCFT deficiency may mimic severe combined immune deficiency (SCID). We report a 4-month-old female who presented with failure to thrive, normocytic anemia, Pneumocystis jirovecii pneumonia and systemic cytomegalovirus infection. Immunolo...

Introduction: Severe acute respiratory syndrome causing coronavirus SARS-CoV-2 (coronavirus disease 2019 (COVID-19)) has recently resulted in the recent global pandemic. As convalescent plasma (CP) therapy been used with success several viral infections before, it become a treatment of choice. Medical literature is reviewed for randomized controlled studies using therapy.Areas covered: More tha...

CD69 is rapidly upregulated on T cells upon activation. In this work we show that this is also the case for CD69 expression on dendritic cells (DC). Thus, the expression kinetics of CD69 on both cell types is reminiscent of the one of costimulatory molecules. Using mouse models of transgenic T cells, we aimed at evaluating the effect of monoclonal antibody (MAb)-based targeting and gene deficie...

introduction bacillus calmette-guérin (bcg) vaccine, a live attenuated mycobacterium bovis strain, is administrated to all newborn infants in endemic regions according to the current world health organization (who) recommendation. case presentation we report a 10-month-boy who was a known case of severe combined immunodeficiency (scid) admitted with multi-focal fusiform painful swelling in his ...

Immunodeficiency and autoimmune disease may occur concomitantly in the same individual. Some of the immunodeficiency syndromes, especially humoral defects are associated with autoimmune disorders. Hematological manifestations such as thrombocytopenia and hemolytic anemia are the most common presentations. Persistent antigen stimulation due to an inherent defect in the ability of the immune syst...

We have shown that cytotoxic lymphocytes generated in primary cultures of NZB spleen cells with H-2-identical BALB/c or B10.D2 stimulator cells exhibit specificity for Qa-1b-associated antigenic determinants. This unidirectional cytotoxicity constitutes the initial demonstration of a primary in vitro response to antigens of the Qa-Tla system. Such responses do not require H-2 homology between e...

Common variable immune deficiency (CVID) is one of the most commonly diagnosed primary immunodeficiencies. Generally, patients have a history of recurrent sinopulmonary infections, hypogammaglobulinemia of two or more immunoglobulin isotypes, and impaired functional antibody responses. Reports of corneal involvement associated with CVID are limited. We describe a case of corneal ulceration asso...

Autism is a neurodevelopmental disorder, characterized by poor social interaction and communication impairment and repetitive behavior. Autism is considered as a genetic and multifactorial disorder, with diverse risk factors involved.Herein, we report a 13-year-old male with common variable immunodeficiency (CVID), who was diagnosed with autism at the age of 3 years old. As there are some evide...

A 20-month-old Indian boy presented with recurrent pyogenic infections and failure to thrive. His IgG and IgA levels were low, but his IgM was elevated. He also had undetectable isohaemagglutinin titre and neutropenia, both parameters being poor prognostic indicators in this very rare primary immunodeficiency state--antibody deficiency with hyper IgM. Our patient subsequently succumbed to Pseud...
