Use of cultured epithelial cells, including keratinocytes, for the detection of antinuclear antibodies.

The use of cultured human epithelial cells as a substrate for the detection of antinuclear antibodies (ANAs) improves the sensitivity of detection above the standard substrates used. Standard antisera have been screened against a series of epithelial cell lines, including keratinocytes. Selected cells have then been used to detect ANAs in 78 patients with discoid lupus erythematosus.

Hydroxychloroquine and lupus pregnancy: review of a series of 36 cases.

OBJECTIVE: To study maternal and fetal outcome of pregnancy in patients with lupus who were exposed to hydroxychloroquine (HCQ). METHODS: The case records of women (n = 33) exposed to HCQ during their pregnancies (n = 36) and of 53 control patients from a single lupus pregnancy centre were reviewed to determine lupus activity, obstetric experience, and infant outcome. RESULTS: HCQ was not apparently teratogenic. Lupus activity and obstetric outcome in the two groups were similar. CONCLUSION: HCQ continuation is probably safe during pregnancy in patients with lupus, but there is no obvious advantage in commencing treatment.

External ocular findings in lupus erythematosus: a clinical and immunopathological study.

A selected group of 18 patients with systemic lupus erythematosus (SLE) and 30 patients with chronic cutaneous lupus erythematosus (CCLE) showed an unexpectedly high incidence of problems involving the globe or eyelids. Five SLE patients had recurrent episcleritis, two CCLE patients had lower tarsal plaques, and two further CCLE patients had erosion of the lower lid margins associated with conjunctival scarring and symblepharon. This association has not previously been reported. There was an unexpectedly high incidence of deposition of immunoreactants in a linear pattern at the basement membrane zone in normal bulbar conjunctiva, which occurred in both SLE (42%) and CCLE (50%). The significance of these findings is discussed. We believe surface ocular problems in lupus erythematosus to be under-reported and that direct immunofluorescence of bulbar conjunctival biopsy might be helpful in diagnosis.

Indirect cutaneous immunofluorescence. II. Clinical significance.

Sera of 532 patients with bullous diseases, connective tissue diseases and malignancies were tested for pemphigus epidermal intercellular fluorescence (ICF) and for the bullous pemphigoid ;tubular' band by the indirect fluorescent antibody technique. Human normal skin cryostat sections were used. The band and ICF were seen primarily only in bullous pemphigoid and pemphigus respectively, Some indirect band and ICF-negative patients demonstrated positive direct results in involved skin. suggesting that direct tests should be performed in indirect negative patients clinically thought to have pemphigus or bullous pemphigoid. No close correlation was found between disease activity and positive or negative indirect tests in bullous pemphigoid and pemphigus. Steroids did not interfere with positive results of this diagnostically extremely valuable test.

Papular and nodular mucinosis as a sign of lupus erythematosus.

We describe 3 cases of papular and nodular mucinosis (PNM), a clinically distinctive cutaneous mucinosis associated with lupus erythematosus (LE), which has received little attention in the dermatologic literature. Histopathology shows deposits of mucin in the dermis without microscopic features of LE, while immunofluorescent studies disclose linear or granular deposits of IgG, IgM and C3 at the dermoepidermal junction. In about 80% of the 14 cases described in the literature, PMN has been associated with systemic LE with prevalent joint and kidney involvement. The possible prognostic significance of this singular dermatosis is discussed.

15-year survey of tinea faciei in the adult.

In a series of 100 adults with tinea faciei various dermatologic manifestations were mimicked, viz.: discoid lupus erythematosus in 52 patients, lymphocytic infiltration in 15, seborrheic dermatitis in 11, rosacea in 8, contacts dermatitis in 7, polymorphous light eruption in 4 and granuloma faciale in 3. Trichophyton rubrum was isolated in 78% of the respective cases, other isolated organisms being Microsporum canis (13 cases), Trichophyton violaceum in 6, Trichophyton mentagrophytes (asteroides) in 2 and Epidermophyton floccosum in 1 case. In 85% of these patients the nails were also involved by the same agent found in the lesions of the face. On the basis of these observations it is recommended that all adult patients with tinea faciei should undergo a comprehensive mycological investigation to find the primary focus, which may be an infected nail.

Clofazimine-mediated enhancement of reactive oxidant production by human phagocytes as a possible therapeutic mechanism.

Clofazimine, at concentrations within the therapeutic range (0.01-5 micrograms/ml), stimulated human polymorphonuclear leucocytes (PMNL) to generate increased amounts of reactive oxidants (RO) when activated with the tripeptide leucoattractant N-formyl-L-methionyl-L-leucyl-L-phenylalanine (FMLP), calcium ionophore, phorbol myristate acetate and opsonised zymosan. Clofazimine per se did not activate the membrane-associated oxidative metabolism of PMNL, but rather primed these cells to hyperreact to the various stimuli. To investigate the therapeutic significance of these observations clofazimine was administered to patients with various chronic inflammatory diseases (lichen planus, discoid lupus erythematosus and rheumatoid arthritis) and generation of RO by FMLP-activated phagocytes was measured before and during clofazimine administration. A statistically significant potentiation of RO generation by FMLP-activated phagocytes was observed during clofazimine administration. Since RO are immunosuppressive and antimicrobial the therapeutic mechanisms of clofazimine may be related to pro-oxidative interactions of this agent with phagocytes.
