Precipitins

01/15/1989 - "The results of a bronchial challenge to Aspergillus species, however, remained positive; these positive results suggest that long-term memory immune mechanisms may play an important role in the pathogenesis of hypersensitivity pneumonitis and lessen the importance of precipitins in establishing a diagnosis. "
01/01/1980 - "A study was made of the prevalence of serum precipitins to Micropolyspora faeni, Thermoactinomyces vulgaris, Aspergillus fumigatus, and pigeon serum in population groups suspected to be at high risk for the development of hypersensitivity pneumonitis. "
04/01/2007 - "Serum precipitins have a controversial diagnostic value in hypersensitivity pneumonitis (HP). "
02/01/2003 - "[Hypersensitivity pneumonitis: a technical note on precipitins]."
07/01/1998 - "Hypersensitivity pneumonitis affected seven workers, with six exhibiting serum precipitins to Acinetobacter Iwoffii. "

04/01/1977 - "Quantitation of candida serum precipitins by counterimmunoelectrophoresis is helpful in diagnosing significant candidiasis."
09/01/1978 - "Yeasts, mainly Candida albicans, were isolated from the mouths of 41% of the outpatients and precipitins were found in 17.5% although none of the patients had clinically overt candidiasis. "
04/01/1977 - "Detection of candida serum precipitins by counterimmunoelectrophoresis: an adjunct in determining significant candidiasis."
03/01/1977 - "Precipitins were present in 20% of sera of women with vaginal candidiasis, in 23% of women harbouring yeasts in the vagina without clinical signs of infection, and in 21% of women harbouring yeasts in sites other than the vagina. "
01/01/1981 - "In another 4 patients, the precipitins were positive against metabolic antigen only and further study failed to show deep candidiasis. "

03/01/1976 - "These studies show that precipitins SS-A and SS-B are present in high frequency in sera of patients with SS without associated rheuamtoid arthritis (RA) and are absent or present in low frequency in many other connective tissue diseases. "
06/01/1984 - "Precipitins were rare in patients with polyarteritis nodosa (PAN) and their absence helped to distinguish PAN from vasculitis associated with other connective tissue diseases. "

06/01/1984 - "Precipitins were detected in some patients with other vasculitides. "
10/01/1976 - "We describe a 46 year old women with a seven year history of urticarial-like symptoms and cutaneous vasculitis with marked deficiency of C1q in the presence of normal levels of C1r and C1s and high titers of low molecular weight (7S) C1q precipitins. "
02/01/1975 - "The sera from two well-documented cases of allergic vasculitis were examined for the presence of C1q precipitins. "
06/01/1984 - "Precipitins were rare in patients with polyarteritis nodosa (PAN) and their absence helped to distinguish PAN from vasculitis associated with other connective tissue diseases. "
11/01/1981 - "The detectable immune complexes were of high molecular weight, and were more suggestive of classical lupus erythematosus than the low molecular weight (7S) Clq precipitins which characterize some cases of hypocomplementemia-vasculitis-urticaria syndrome. "

01/01/1999 - "Diagnosis is based on simultaneous presence of most of the following arguments: exposure to a known risk factor, spontaneous improvement after cessation of the exposure, identification of specific precipitins, demonstrative aspects on X-ray and tomodensitometry, and CD8+ lymphocytosis in bronchoalveolar lavage. "
04/01/2005 - "Broncho-alveolar lavage revealed a marked lymphocytosis (63%) and precipitins for Microsporum Faeni were strongly positive (6 arcs). "
04/01/2004 - "Four HRCTs showed signs of minimal parenchymal abnormalities; these were not more prevalent for subjects with or without precipitins or BAL lymphocytosis. "
05/01/1986 - "We previously demonstrated that 14 of 23 asymptomatic dairy farmers with positive precipitins and 5 of 20 without precipitins had an alveolar lymphocytosis (greater than 22%). "
