Mucosal immune system activation may represent a critical determinant of adverse consequences associated with bacterial vaginosis (BV), such as sexual human immunodeficiency virus transmission, upper genital tract infections, postsurgical infections, and adverse pregnancy outcomes. Concentrations of sialidase, prolidase, and anti-Gardnerella vaginalis hemolysin (Gvh) immunoglobulin A (IgA) were higher in vaginal fluids of 75 fertile women with BV, compared with concentrations in vaginal fluids of 85 healthy control subjects. Interleukin (IL)-8 levels were positively associated with anti-Gvh IgA response and inversely correlated with high levels of prolidase and sialidase in women with BV. IL-8 concentration was strongly associated with leukocyte count in both healthy and BV-positive women. The absence of leukocytes in most women with BV likely is due to lack of IL-8 induction. Parallel impairment of innate and adaptive mucosal immune factors, likely through microbial hydrolytic effects, may allow for the ascent of microorganisms to the upper genital tract and may facilitate viral infections.

The hyper-immunoglobulin E syndrome (HIES) is a rare primary immunodeficiency characterized by recurrent infections, elevated serum IgE-levels, and involvement of the soft- and bony tissues. We speculated that this complex disease may be caused by a microdeletion syndrome. We therefore analyzed 30 sporadic HIES patients for the presence of chromosomal imbalances using Affymetrix 50k XbaI and 23 of the 30 patients with the higher-resolution 250k StyI SNP mapping arrays. We detected only eight different copy number alterations in six patients with the 50k approach, and seven of these presented known polymorphic regions not associated with disease. However, one patient showed a unique gain on chromosome 20p. 250k array analysis identified this gain as a rare polymorphism segregating in the patient's family, but not associated with the HIES phenotype. In addition, 265 known and novel copy number variants (CNVs) were identified with the 250k arrays, but no recurrent imbalances reminescent of a microdeletion syndrome were found. We aligned the identified CNVs with loci that have been associated with HIES or phenotypically overlapping syndromes. Doing so, a 2-Mb deletion spanning the PEPD gene on 19q13.11 was identified on one allele of one patient. Homozygous mutations in PEPD are responsible for the autosomal-recessive prolidase deficiency which resembles HIES in some aspects. Sequencing of the healthy allele, however, revealed a wild-type sequence. In summary, our results suggest that HIES is not likely to be a microdeletion syndrome.
