As expected, the greatest percentage of errors was observed in the group of patients without any kind of medical advice (83%). However, practically the same proportion (79%) failed to use the MDIs properly despite the fact that they were under the supervision of medical outpatient car...

We experienced an 85-year-old male patient with selective IgM deficiency. The average levels of his serum immunoglobulins were as follows: IgG, 1,165 mg/dl, IgA 280 mg/dl, and IgM 17 mg/dl. The subpopulations of peripheral blood lymphocytes in this patient were normal, including normal numbers of IgM-bearing lymphocytes. Normal amounts of cells with cytoplasmic IgM were induced by in vitro addi...

Common variable immunodeficiency (CVID) and IgA deficiency (IgAD) are primary humoral immune deficiencies with a similar genetic background, but clinical and laboratory manifestation of CVID is much more severe than that of IgAD. The aim of this study was to determine whether some abnormalities in T-lymphocyte subsets or function observed in CVID are also present in IgAD patients. T-lymphocyte ...

Macroamylasaemia and selective IgA deficiency were diagnosed in a 2 year old child who presented with persistent hyperamylasaemia. Macroamylasaemia is an isolated biochemical abnormality caused by aggregation of serum amylase activity with immunoglobulins. Early recognition of macroamylasaemia is important to avoid diagnosing pancreatic disease.

Jejunal biopsies from 20 well nourished children (average age 12.8 months) with gastroenteritis, and 20 children (average age 20 months) with protein-energy malnutrition were examined by immunofluorescent technique for immunoglobulins A, G, M, E, and D, and for epithelial glycoprotein secretory component. Compared with previous studies on normal infants, the children with gastroenteritis showed...
