Sixty steroid-treated patients with asthma were evaluated for the presence of muscle weakness by use of both manual muscle testing and the Cybex II isokinetic dynamometer. The patients were compared to age and sex-matched sedentary control subjects. Forty-eight percent of the patients (12/25) taking greater than or equal to 40 mg per day of prednisone had hip flexor strength greater than or equal to 2 SD below the mean of age and sex-matched control subjects by Cybex testing (CT). Sixty-four percent of the patients (16/25) taking greater than or equal to 40 mg per day of prednisone were found on manual muscle testing to have hip flexor weakness. Only one patient taking less than 30 mg per day of prednisone was found to have muscle weakness. Biochemical parameters, including CPK, aldolase, SGOT, LDH, and LDH isoenzymes were measured to assess the degree of steroid-induced muscle damage. They neither correlated with the degree of hip flexor weakness as measured by CT, nor did they discriminate between patients receiving small doses and large doses of steroids. Changes in urinary excretion of creatine did not help to confirm the diagnosis of steroid myopathy. Although CT provides an objective means of assessing muscle strength in these patients, at this time no definitive chemical test is available for the diagnosis of steroid myopathy.

Although airborne allergens in bakeries and confectioneries cause one of the most common forms of occupational asthma, namely, bakers' asthma, only a few of them are known in detail so far. Here we summarize current knowledge of bakery allergens and describe our own two-dimensional (2-D) immunoelectrophoresis studies of wheat-flour allergens as well as the allergenic baking enzyme Asp o 2. Out of approximately 700 soluble wheat polypeptides, 70 show IgE binding; the following wheat-flour allergens could be identified and characterized: members of the alpha-amylase inhibitor family (14-18 kDa), acyl-CoA oxidase (26 kDa), peroxidase (36 kDa), and fructose-bisphosphate aldolase (37 kDa). However, the great majority of the soluble wheat-flour allergens, mainly located in the 27-, 55-, and 70-kDa areas of the 2-D immunoblots with pI values of 5.8-6.8, 5.9-6.5, and 5.5-6.1, respectively, are not known at present. Asp o 2, to which approximately 25% of all bakers with respiratory symptoms are sensitized, is a well-characterized starch-cleaving enzyme. We conclude that great effort is still needed to describe all major wheat-flour allergens. As shown by Asp o 2, knowledge of the causative allergens and their characteristics enables us to initiate very effective preventive measures such as the introduction of granulated allergenic products.

The aim of the studies was to identify the regulatory mechanisms that act at different levels of the ongoing immune response in BALB/c mice infected with intestinal nematode H. polygyrus. The role of TGF-beta during the course of H. polygyrus infection and an immunosuppressive action of the nematode against eosinophil response in allergic pulmonary inflammation has been studied. An attempt to identify the immunoregulatory proteins of the parasite has been performed as well. The obtained results proved: (1) for the first time the direct role of TGF-beta in the regulation of the immune response during helminth infections. Neutralization of TGF-beta in vivo increased concentration of IL-12, TNF-alpha and IL-10 in serum of infected mice and restored the control number of eosinophils in the intestinal mucosa. The mobilization of the immune response after neutralization of TGF-beta led to persistent decrease of nematode egg production and faster rejection of the worm from mouse intestine; (2) for the first time it was shown that the reduction of eosinophil number was due to the lower production of eotaxin and reduced expression of CCR3 receptor, playing an essential role in the chemotaxis of these leukocytes in Ova-related asthma; (3) significant decrease of T cell proliferation by one of the H. polygyrus protein fraction. With the use of mass spectrometry seven proteins have been identified: two heat shock proteins, disulfide isomerase, calreticulin, calumenin, fructose-bisphosphate aldolase, glyceraldehyde-3-phosphate dehydrogenase. From the bibliographic data it may be supposed that calreticulin could mediate the downregulation of lymphocytes proliferation. The fraction with calreticulin stimulated also production of specific IgE.

Although cockroaches are known to produce allergens that can cause IgE-mediated hypersensitivity reactions, including perennial rhinitis and asthma, the various cockroach allergens have not yet been fully studied. Many proteins from the German cockroach show high IgE reactivity, but have never been comprehensively characterized. To identify these potential allergens, proteins were separated by 2-DE and IgE-binding proteins were analyzed by nanoLC-MS/MS or N-terminal sequencing analysis. Using a combination of proteomic techniques and bioinformatic allergen database analysis, we identified a total of ten new B. germanica IgE-binding proteins. Of these, aldolase, arginine kinase, enolase, Hsp70, triosephosphate isomerase, and vitellogenin have been reported as allergens in species other than B. germanica. Analysis of the Food Allergy Research and Resource Program allergen database indicated that arginine kinase, enolase, and triosephosphate isomerase showed significant potential cross-reactivity with other related allergens. This study revealed that vitellogenin is an important novel B. germanica allergen. Personalized profiling and reactivity of IgE Abs against the panel of IgE-binding proteins varied between cockroach-allergic individuals. These findings make it possible to monitor the individual IgE reactivity profile of each patient and facilitate personalized immunotherapies for German cockroach allergy disorders.
