This study was conducted to determine the sensitivity to Dermatophagoides pteronyssinus (Trouessart) and D. farinae Hughes with skin prick tests (SPT) and serologic tests in patients with allergic rhinitis (AR), and to specifically search for those mites in homes of patients. A total of 51 participants, (23 patients and 28 controls) were utilized. Skin-prick tests with D. pteronyssinus and D. farinae allergens were performed on all participants, and serum levels of allergen-specific lgE and total IgE were also measured. Dust samples were collected from homes of all participants and examined under a stereo microscope. 977 D. pteronyssinus (mean 44.4/g) and 24 D. farinae (mean 4.0/g) were isolated from the homes of patients, whereas 35 D. pteronyssinus (mean 4.4/g), and four D. farinae (mean 2.0/g) were isolated from the homes of the controls. Patients with D. pteronyssinus in their homes had 95.5% sensitivity to the species according to SPT and 27.3 according to IgE. Patients with D. farinae in their homes had 83.3% sensitivity to the species according to SPT, and 50% according to IgE. Dermatophagoides pteronyssinus sensitivity in the controls was detected as 12.5% according to SPT; however, D. farinae sensitivity was not detected according to both SPT and mite-specific IgE. Differences between patients and controls utilizing SPT results was statistically significant, but not when using mite-specific IgE results. As a result, it was determined that patients with AR in Erzincan province were sensitized to D. pteronyssinus and D. farinae, and that their homes contained those species. It may be helpful to consider these findings in clinical assessment of patients with AR, and also in treatment utilizing immunotherapy techniques.

Nasal Provocation Testing

Background Allergen identification is the first step for allergen-specific immunotherapy (AIT) of allergic rhinitis (AR). Currently, the diagnosis of AR is based mainly on the positive results of the skin prick test (SPT) and/or serum specific immunoglobulin E (sIgE) measurement. However, the results of these two tests may not always directly correlate with AR. Objective To investigate the importance of nasal provocation testing (NPT) in the diagnosis of Dermatophagoides pteronyssinus (Der p)-induced AR. Methods Rhinitis patients willing to undergo AIT (n = 171) were enrolled. The correlations of Der p SPT, sIgE, NPT, and clinical symptom severity were assessed. Results NPT-positive responses were more common in patients with higher SPT and sIgE levels. The optimal cut-off value for a NPT-positive response for SPT was 5.5 mm and for sIgE was 2.77 kUA/L, based on the respective receiver operating characteristic (ROC) curves. The area under the curve (AUC) of the ROCs was 0.814 (SPT only) and 0.794 (sIgE only) and increased to 0.828 with the combination of SPT and sIgE. The Der p-NPT concentration was inversely correlated with SPT and sIgE levels ( r = −0.477, P < .001, and r = −0.461, P < .001, respectively), but none was correlated with the total nasal symptom score. Conclusion For patients who are willing to receive Der p AIT, NPT is a useful and safe test to confirm diagnosis prior to treatment initiation, especially in patients with lower levels of Der p SPT (< 5.5 mm) or sIgE (< 2.77 kUA/L).

The survey of the sublittoral fauna of the Clyde Sea Area from 1949 onwards has shown that five species of the Protobranchiata are abundant throughout this region on a variety of substrata. Pelseneer (1891, 1899, 1911), Heath (1937), and Yonge (1939) have contributed much to the knowledge of the group as a whole, but little comparative work has been done at species level. Verrill & Bush (1897, 1898) studied the shell characters of the American Atlantic species. Moore (1931 a, b) worked on the faecal pellets of the British Nuculidae and attempted to distinguish the species by this means, while Winckworth (1930,1931), mainly in the light of the latter work, attempted to clarify the nomenclature of these species. Winckworth (1932) lists six British species of the family Nuculidae: Nucula sulcata Bronn, N. nucleus (Linné), N. hanleyi Winckworth, N. turgida Leckenby & Marshall, N. moorei Winckworth and N. tenuis (Montagu); and four species of the family Nuculanidae: Nuculana minuta (Müller), Yoldiella lucida (Loven), Y. tomlini Winckworth and Phaseolus pusillus (Jeffreys). All species of Nucula, except N. hanleyi, were taken from the Clyde Sea Area, although the latter species is included in the Clyde fauna list (Scott Elliot, Laurie & Murdoch, 1901). Only Nuculana minuta of the Nuculanidae has been taken on the present survey. Yoldiella tomlini is included in the 1901 list but is noted as being ‘insufficiently attested’. Nucula hanleyi was obtained from the Marine Station, Port Erin, but Yoldiella and Phaseolus were unobtainable.
