Humoral deficiencies represent a broad group of disorders. The aim of the study was to compare the levels of antibodies against pneumococcal capsular polysaccharides (anti-PCP) and natural anti-galactosyl (anti-Gal) antibodies in (1) patients with chronic lymphocytic leukaemia (CLL), (2) patients with common variable immunodeficiency (CVID), and (3) a healthy population and to explore their dia...
Secondary antibody deficiency can occur as a result of haematological malignancies or certain medications, but not much is known about the clinical and immunological features of this group of patients as a whole. Here we describe a cohort of 167 patients with primary or secondary antibody deficiencies on immunoglobulin (Ig)-replacement treatment. The demographics, causes of immunodeficiency, di...
Mixed infections are one of the major therapeutic challenges, as the current strategies have had limited success. One of the most common and widespread conditions of mixed infection is respiratory syncytial virus-mediated pathology of the respiratory tract in children. There is a dire need for the development of novel therapeutic approaches during mixed infections. Therapeutic intravenous immun...
Hematopoietic stem cell transplantation is characterized by a prolonged period of humoral immunodeficiency. We have previously shown that the deficiencies are probably not due to the failure to utilize the appropriate V regions in the pre-immune repertoire. However, a striking observation, which correlated with the absence of immunoglobulin IgD(-) cells and was consistent with a defect in antig...
We show that Ugandan adults coinfected with Schistosoma mansoni and human immunodeficiency virus type 1 (HIV-1) are able to mount S. mansoni-specific immune responses but that few such responses increase after treatment with praziquantel (PZQ). Levels of soluble worm antigen (SWA)-specific immunoglobulin (Ig) G1, IgG2, IgG3, IgG4, interleukin (IL)-4, and IL-5 increased significantly in HIV-nega...
Growth hormone deficiency (GHD) may be associated with a number of immunodeficiency diseases, but its association with immunoglobulin class switch recombination (Ig CSR) deficiencies is very rare. We report the case of a patient with a history of recurrent diarrhea and respiratory infections diagnosed with hyper IgM syndrome on the basis of immunological findings (low serum levels of IgG and Ig...
background: children with idiopathic thrombocytopenic purpura who are treated with intravenous immunoglobulin therapy might experience a decline in their absolute neutrophil count. the aim of this study was to investigate the incidence of neutropenia following intravenous immunoglobulin therapy in children with idiopathic thrombocytopenic purpura undergoing intravenous immunoglobulin therapy. p...
CHARGE syndrome is a variable, multiple congenital malformation syndrome. Patients with CHARGE syndrome have frequent infections that are presumed to be due to anatomical anomalies of the craniofacial region and upper airway, and cranial nerve problems resulting in swallowing difficulties and aspiration. The possible contribution of immunological abnormalities to these infections has not been s...
Non-homologous end joining (NHEJ) is a key cellular process ensuring genome integrity. Mutations in several components of the NHEJ pathway have been identified, often associated with severe combined immunodeficiency (SCID), consistent with the requirement for NHEJ during V(D)J recombination to ensure diversity of the adaptive immune system. In contrast, we have recently found that biallelic mut...
Common variable immunodeficiency (CVID) is the most common symptomatic primary immunodeficiency disease, predisposing the patients to various tissue involvement and organ damage. Here a 16-year-old boy is presented who was referred to our center with cough, dyspnea, cyanosis, and history of recurrent pneumonia. The diagnosis of CVID was made according to reduction all serum immunoglobulin level...
