Vulvitis granulomatosa: a cryptogenic chronic inflammatory hypertrophy of vulvar labia related to cheilitis granulomatosa and Crohn's disease.

We report the cases of two patients with vulvitis granulomatosa, a chronic inflammatory hypertrophy of the vulvar labia thought to represent the vulvar variant of cheilitis granulomatosa. One of the women later experienced recurring cheilitis granulomatosa, while the other developed intestinal Crohn's disease 6 years later. The interrelationships of vulvitis granulomatosa, cheilitis granulomatosa, and Crohn's disease are discussed.

Induction of MHC class I antigen expression following infection of a human esthesioneuroblastoma cell line with cytomegalovirus and human immunodeficiency virus.

Productive infections with cytomegalovirus (CMV) and human immunodeficiency virus (HIV) were established in the Tp41ON cell line derived from a human esthesioneuroblastoma. HIV antigen expression was highest in cultures coinfected with CMV and HIV. Viral infection caused increased MHC class I antigen expression while class II and CD4 antigens remained undetectable using immunofluorescence methods. Uninfected cultures showed 10% and coinfected cultures 80% class I antigen positive cells. In coinfected cultures, CMV and HIV antigens were detected in 4% and 8% of the cells, respectively. The detection of CMV antigens in some multinucleated cells suggests coinfection with both viruses in these cells, as multinucleated cells were not found in cultures infected with CMV only. The study shows that a cell line showing neuronal differentiation in vitro can be infected with CMV and HIV and that this infection increases MHC class I antigen expression.

Human immunodeficiency virus type 1 p24 production and antigenic variation in tissue culture of isolates with various growth characteristics.

Two monoclonal antibodies (Mabs) reacting with different epitopes of the human immunodeficiency virus type 1 core protein p24 (HIV p24) were used either singly or in combination as tracers in enzyme-linked immunosorbent assays. The culture supernatant of 215 samples of peripheral blood mononuclear cells from 112 patients were measured for HIV p24 and reverse transcriptase (RT) activity during cultivation. One hundred forty-one cultures were positive for HIV p24 and 122 for RT after 32 days of cultivation. After 8-9 days, HIV p24 was detected in 50.4% and RT in 27.8% of the cultures later judged as HIV positive. Two patients seemed to have substrains of HIV-1 not reactive with one of the Mabs.

Acid hydrolysis of serum samples to increase detection of HIV antigen.

Sera from 32 HIV-infected patients and 20 controls were assayed for HIV antigen (HIV-Ag) and antibodies following acid hydrolysis. Acid hydrolysis, followed by neutralization immediately prior to the assay, was found to be a simple means to solubilize immune complexes and allowed recovery of 40-50% of complexed antigen. Following acid hydrolysis, HIV-Ag levels rose or became detectable in 22/32 patients and HIV IgG1-4 levels rose in 17/20 patients studied. The results show that complexed HIV-Ag may evade detection in HIV-infected patients.
