abstract kawasaki disease is a systemic vasculitis that mainly affects younger children. although the definite cause still remains unknown but the clinical and epidemiologic findings discuss an infectious cause. the prevalence of incomplete kawasaki disease reported 15 to 36.2%, and it is more frequent in the extremes of the age spectrum. non delayed treatment of disease should be initiated bec...
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. ...
B cell-negative severe combined immunodeficiency (SCID) is caused by molecules involved in the variable (diversity) joining (V[D]J) recombination process. Four genes involved in the nonhomologous end joining pathway--Artemis, DNA-PKcs, DNA ligase 4, and Cernunnos--are involved in B cell-negative radiosensitive SCID. Deficiencies in DNA ligase 4 and the recently described Cernunnos gene result i...
Somatic hypermutation (SHM) and class switch recombination (CSR) allow B cells to make high affinity antibodies of various isotypes. Both processes are initiated by activation-induced cytidine deaminase (AID) to generate dG:dU mismatches in the immunoglobulin genes that are resolved differently in SHM and CSR to introduce point mutations and recombination, respectively. The MutL homolog MLH3 ha...
BACKGROUND Patients with syndromic features frequently suffer from recurrent respiratory infections, but little is known about the spectrum of immunological abnormalities associated with their underlying chromosomal aberrations outside the well-known examples of Down and DiGeorge syndromes. Therefore, we performed this retrospective, observational survey study. METHODS All members of the Euro...
A retrospective audit was conducted of all issues of rabies vaccine or human rabies immunoglobulin (HRIG) from the Clinical Microbiology Department at University Hospital Aintree for post-exposure prophylaxis. The appropriateness of management was reviewed by a blinded panel, which used guidelines issued by the Health Protection Agency (HPA) as a standard. Thirty-six enquiries, on average 9 day...
Congenital central hypothyroidism (CCH) is a very rare disease. Alterations in pituitary development genes as well as mutations of immunoglobulin superfamily member 1 and transducin β-like protein 1 can result in CCH and multiple pituitary hormone deficiencies. However, mutations of the thyrotropin-releasing hormone receptor or thyroid-stimulating hormone-beta (TSHB) gene are responsible for is...
Autosomal deletion syndromes are of great interest since measurable loss of genetic material could lead to the mapping of the human autosomes. Short arm deletions and long arm deletions of chromosome 18 have been described in association with phenotypic changes (Grouchy et al., 1963, 1964) and reviewed recently by Wolf et al. (1967) and Reinwein, Ritter, and Wolf (1967). Since a ring chromosome...
1AJBORATORY EVALUATION of the J efficacy of typhoid vaccine has generally produced results which show little correlation with those obtained in field-trial evaluation. Hence, extensive field trials have been deemed necessary to evaluate the various typhoid vaccines {1-S). Recent advances in immunological methodology have demonstrated distinct classes of immunoglobulins with differing bio¬ logic...
Intravenous immunoglobulin administered at replacement dosages modulates innate and adaptive immune cells in primary antibody deficiencies (PAD) in a different manner to what observed when high dosages are used or when their effect is analyzed by in vitro experimental conditions. The effects seem to be beneficial on innate cells in that dendritic cells maturate, pro-inflammatory monocytes decre...
