Abstract
We measured using a competitive quantitative polymerase chain reaction-capillary electrophoresis (PCR-CE)-based assay, the levels of bcr-abl transcripts in 44 patients with chronic myeloid leukemia (CML) after interferon-alpha (IFN-alpha) therapy, who achieved a major (10 patients, MCR group) or complete (34 patients, CCR group) cytogenetic response. All 34 CCR patients had molecular evidence of residual disease detected in bone marrow samples at the time of best karyotypic response. The median number of bcr-abl transcripts of 34 evaluable patients in the CCR group at the time of complete cytogenetic remission was 4/microg RNA (range 3-4600), while the median number of bcr-abl transcripts of 10 patients in the MCR group at the time of best cytogenetic response was 4490/microg RNA (range 600-23 900) (P = 0.000024). In nine CCR and five MCR patients we were able to quantify the amount of bcr-abl transcript both at diagnosis and after interferon therapy: no statistical difference (P = 0.18) was found between the two groups at diagnosis (median bcr-abl transcripts/microg RNA was 30 000 vs. 39 650, respectively). During IFN-alpha therapy, the two groups were evaluable at the time of major karyotypic conversion: at this point, there was a statistical difference of expression of bcr-abl transcript between the CCR group (17 patients) (median 2700; range 76-40 000) and the MCR group (10 patients) (median 4490; range 600-23 900), respectively (P = 0.046). No differences of bcr-abl amount of transcript were found in patients with CCR obtained either by IFN-alpha therapy alone (20 patients) vs. IFN-alpha plus ABMT (13 patients) (P = 0.47). We firstly demonstrated that although the CCR and MCR groups were clinically, cytogenetically and molecularly indistinguishable at diagnosis, the two groups could be recognized successfully during interferon therapy based on the level of bcr-abl transcript.

Abstract
In vitro hemopoiesis and hemopoietic cytokines production were evaluated in 9 centenarians (median age 100.5 years, age range: 100-104 years), 10 old people (median age: 71 years, age range: 66-73 years), and 10 young people (median age: 35 years, age range: 30-45 years), all carefully selected for their healthy status. The main findings were the following: (i) a trend towards a decreased absolute number of CD34+ progenitor cells in the peripheral blood of old people and centenarians, in comparison to young subjects; (ii) a well-preserved capability of CD34+ cells from old people and centenarians to respond to hemopoietic cytokines, and to form erythroid (BFU-E), granulocyte-macrophagic (CFU-GM), and mixed colonies (CFU-GEMM) in a way (number, size, and morphology) indistinguishable from that of young subjects; (iii) an age-related decreased in vitro production of granulocyte-macrophagic colony-stimulating factor (GM-CSF) and a decreased production of interleukin-3 (IL-3) in centenarians by phytohemagglutinin (PHA)-stimulated peripheral blood mononuclear cells (PBMC); (iv) a linear increase of the serum level of stem cell factor (SCF), measured in the above-mentioned subjects and in 65 additional subjects, including 4 centenarians. These data suggest that basal hematopoietic potential is well preserved in healthy centenarians, and that the hemopoietic cytokine network undergoes a complex remodeling with age.

Abstract
Fluticasone propionate aqueous nasal spray (FPANS) is a topically active glucocorticoid which has been successfully used for the treatment of seasonal allergic rhinitis (SAR). Topical levocabastine is a highly selective H1 antagonist which has been proposed as an alternative treatment of SAR. The purpose of this study was to compare the clinical efficacy of two topical nasal treatments, FPANS and levocabastine, in the treatment of SAR. Additionally, the effect of treatments on nasal inflammation was examined during natural pollen exposure. A group of 288 adolescent and adult patients with at least a 2-year history of SAR to seasonal pollens participated in a multicenter, doubleblind, double-dummy, and placebo-controlled study. Patients were treated with either FPANS 200 microg, once daily (n = 97), or topical levocabastine, 200 microg, given twice daily (n = 96), or matched placebo (n = 95) for a period of 6 weeks, starting from the expected beginning of the pollen season. Clinically relevant pollens included Parietaria, olive, and grass. Assessment of efficacy was based on scores of daily nasal symptoms and on nasal cytology of nasal lavage. Nasal lavage was performed immediately before, during, and at the end of treatment in 39 patients. FPANS significantly increased the percentage of symptom-free days for nasal obstruction on waking and during the day, rhinorrhea, sneezing, and itching. FPANS provided a better control for night and day nasal obstruction (P<0.02 and P<0.01) and rhinorrhea (P<0.01) than levocabas tine. In addition, fewer patients treated with FPANS used rescue medication (P<0.025). The percentage of eosinophils in nasal lavage was reduced only during treatment with FPANS. The results of this study indicate that FPANS 200 microg, once daily, provides a better clinical effect than levocabastine 200 microg, twice daily, in patients with SAR. Unlike levocabastine, FPANS significantly attenuates nasal eosinophilia during pollen exposure, a feature which may explain its therapeutic efficacy.

Abstract
Rhinitis is defined as nasal congestion, sneezing, itching and rhinorrhoea, recently classified as allergic, infective, structural or "other". The increasing employment of flexible rhynolaringoscopy may represent one of the most useful diagnostic tools in the complex differential diagnosis between allergic and nonallergic rhinitis. Furthermore, chronic allergic rhinitis, with secondary impairment of mucociliary clearance and the plethora of frequent anatomical variations, especially in the ostiomeatal complex, appear to predispose the patient to recurrent rhinosinusitis. In the last two decades, a better understanding of mucociliary clearance of nasal cavity and paranasal sinuses has shifted the attention from the maxillary sinuses to the area of the antherior ethmoid sinuses. Plain film radiographic examination, the historical standard, due to its inability to individualize ethmoid and sphenoid disease, is being rapidly supplanted by computed tomography and magnetic resonance imaging in the diagnosis of rhinosinusitis. In allergic and non-allergic rhinitis the diagnostic role of magnetic resonance imaging and computed tomography is still under debate. Computed tomography and magnetic resonance imaging are more efficient in demonstrating the bone wall, mucosal layer and sinus content than classical and computerized radiology; they have a higher diagnostic performance index in spite of a higher cost and, for computed tomography, a higher radiation dose.

Abstract
The prevalence of sensitization to cockroach (CR) was evaluated by skin prick test (SPT) in 1299 patients consecutively referred for rhinitis and asthma to five allergy centers in northern, central, and southern Italy. In patients with positive SPT to CR, an SPT with D. pteronyssinus extract was made. RAST inhibition was performed with pooled sera of subjects with positive SPT and RAST of at least Class 3 for CR and D. Pteronyssinus, to assess the cross-reactivity between these two allergenic sources. The protein content of allergen extracts was assayed by isoelectric focusing (IEF). A total of 170 patients (13%) had a positive SPT with CR extract, and 133 of them (78.2%) were also positive for D. pteronyssinus. RAST inhibition showed a cross-reactivity between CR and D. pteronyssinus, and IEF detected in the extracts employed a series of bands focusing at the same pI of CR and D. pteronyssinus relevant allergens. Therefore, the prevalence of sensitization to CR in the population studied, corresponding to 13%, suggests that CR extract might be added to standard SPT panels for respiratory allergy. However, the cross-reactivity with D. pteronyssinus calls for careful evaluation of the clinical importance of this sensitization.

Abstract
This study was designed primarily to assess the safety and tolerability of fluticasone propionate (FP) 1 mg day-1 by comparison with beclomethasone dipropionate (BDP) 2 mg day-1 over a 12-month study period. Lung function data were also recorded and used to determine whether the potency ratio between the two inhaled corticosteroids observed in previous studies was maintained in the long-term. Two hundred and thirteen patients with an established clinical history of severe chronic asthma and who were currently receiving between 1000 micrograms and 2000 micrograms day-1 of inhaled steroids were randomized to treatment in a ratio of 3:1 for FP:BDP (159 patients FP; 54 patients BDP), both via metered dose inhalers. Both treatments were well tolerated with a similar adverse event profile. No unexpected adverse events were recorded. Most adverse events were related to the patients' asthma, an intercurrent infection or underlying atopy. The incidence of pharmacologically predictable adverse events was equally low in both treatment groups as was the incidence of events suggestive of systemic steroid effect. Mean serum cortisol levels remained within the normal range at all visits for both treatments. At 12 months, however, the mean cortisol levels for the FP group had risen 4% above the baseline value but had dropped 15% below for the BDP group, giving a ratio of FP:BDP of 1.22; P = 0.01; 95% confidence limits (CL) 1.05-1.43. Fluticasone propionate 1 mg day-1 was at least as effective as BDP 2 mg day-1 in improving lung function (PEF, FEV1 and FVC) over this period. Moreover, the difference in FEV1 values at 6 months was significantly greater for the FP group than for the BDP group (P = 0.04; difference = 0.12 1; 95% CL = 0.01, 0.24 1). The difference between treatments in the amount of FEV1 reversibility was also significantly greater for FP at 12 months (difference in treatments = -3%; 95% CL = - 7-0%; P = 0.044). This study supports previous studies and suggests that FP is likely to be of benefit in the long-term treatment of chronic severe asthma.

Abstract
A group of 28 patients from Italy was studied who had asthma after consumption of snail. All patients also had asthma and/or rhinitis caused by house-dust mite. RAST analyses confirmed the combined sensitization to snail and mite. In a few sera, IgE antibodies reactive with other foods of invertebrate origin (mussel and shrimp) were detected. RAST inhibition showed that most IgE antibodies against snail were cross-reactive with house-dust mite. In contrast, the mite RAST was not significantly inhibited by snail. This indicates that house-dust mite was the sensitizing agent. Immunoblot analyses revealed multiple bands in snail extract recognized by IgE. In contrast to what has been described for cross-reactivity between shrimp and mite, tropomyosin played only a minor role as a cross-reactive allergen in these patients. The observations in this study indicate that snail consumption can cause severe asthmatic symptoms in house-dust-mite-allergic patients. It might, therefore, be advisable to screen mite-allergic asthma patients for allergy to snail and other invertebrate animal foods.

Abstract
The authors describe a case of paradoxical bronchospasm with laryngospasm and cutaneous rash occurring in an asthmatic woman after the use, via metered-dose inhaler, of different bronchodilators containing soy-derived excipients. It is noteworthy that the patient was not affected by soy allergy. After a short review of the relevant literature, the authors consider the possible aetiopathogenetic factors and outline the importance of this rare adverse reaction in the care of asthmatic patients.

Abstract
Sera of 17 patients receiving immunotherapy for house-dust mite allergy were tested for IgE antibodies against snail and shrimp. Serum samples were taken at the start of immunotherapy and 14-20 months later. While the average IgE response to mite, Der p 1, and Der p 2 did not alter significantly, the average response to snail showed a significant increase. This included two conversions from negative to strongly positive. These novel IgE antibodies against snail were shown to be cross-reactive with mite. Three patients had a positive RAST for shrimp. For one of them, a strong increase of IgE against shrimp (and snail) was observed. In 2/3 snail/shrimp-positive sera, IgE antibodies against the cross-reactive allergen tropomyosin from mite, snail, and shrimp were demonstrated. A clear IgE response to snail (> 10% binding in a snail RAST) was confirmed by a positive skin prick test (SPT) for 6/10 patients. The two patients with antitropomyosin IgE also had a positive SPT for shrimp, and demonstrated the oral allergy syndrome (OAS) after eating shrimp. The observations in this study indicate that house-dust mite immunotherapy is accompanied by the induction of IgE against foods, including tropomyosin-reactive IgE. Food allergy (OAS) was observed in patients that had IgE antibodies against this cross-reactive allergen. In conclusion, induction of IgE during mite immunotherapy might occasionally cause allergy to foods of invertebrate animal origin.

Abstract
A daily dose of either terfenadine 120 mg or cetirizine 10 mg was compared in two parallel groups of patients suffering from hay fever. According to a double-blind, double-dummy, randomized design, 28 patients were treated with one of the two drugs once daily in the morning for 2 weeks during the 1990 grass pollen season. The severity of nasal congestion, rhinorrhea, sneezing, nasopharyngeal itching and itchy, watery, red eyes was evaluated by the investigator after a 1-week run-in period and at the end of the treatment. The patients made a daily record of the severity of symptoms on a diary card. In addition, drug-related central nervous system (CNS) effects were assessed at baseline and at the end of the treatment by neuropsychological tests aimed at investigating selective and sustained attention, visuomotor abilities and anxiety, and by quantitative, bit-mapped EEG. Both terfenadine and cetirizine produced a significant improvement in symptoms at endpoint without any significant difference between the two drugs. Drowsiness was referred by one patient in each treatment group. No significant impairment of psychomotor performance occurred with either drug. Quantitative EEG showed a significant power increase in the relative (%) delta band in both groups of treated patients. Although the difference was not statistically significant, a tendency towards greater involvement of the CNS was observed with the use of cetirizine. In conclusion, the results of this study confirm that terfenadine and cetirizine are equally effective in the management of hay fever. Some differentiated untoward EEG changes were also observed in relation to the drugs used, without any variation in neuropsychological performance.

Abstract
The aim of the study was to determine whether a short interval (< 2 months) between two consecutive stings influences the development of Hymenoptera venom allergy. The study compared the sting-interval distribution in 120 allergic patients who experienced a first-time systemic reaction to a Hymenoptera sting, and in 100 healthy controls. A significant difference in sting-interval distribution between the two groups was found (P = 0.0001). In 71 of 120 allergic patients, the sting that provoked the systemic reaction had been preceded by another, completely tolerated sting not more than 2 months before. However, in the control group only four subjects out of 100 had received two consecutive stings within less than 2 months. In conclusion, a short interval between two consecutive stings seems to be a risk factor for the onset of Hymenoptera venom allergy.

Abstract
Fifteen double-blind placebo-controlled studies in pollen and mould asthma have been carried out, the majority with grass pollen immunotherapy. Despite certain methodological limitations, the clinical efficacy was demonstrated in all studies performed. A decrease in specific immediate skin reactivity is relatively common during pollen and mould immunotherapy. In several studies the efficacy of immunotherapy was further indicated by the change in some functional parameters of the airways that sometimes seem to be related to the clinical results. At the moment available data do not indicate that IgG subclasses are useful in predicting the clinical outcome of immunotherapy. Currently the only methods which truly reflect the efficacy of immunotherapy are clinical evaluations. The effectiveness of this treatment is influenced by the quality of allergens used for immunotherapy and better results will probably be achieved in the future after further allergen purification and standardization.

Abstract
Previous studies have documented changes in skin reactivity after specific immunotherapy. The aim of this study was to evaluate the time course of this phenomenon after rush venom immunotherapy. According to the method of endpoint evaluation, the skin reactivity of 38 patients allergic to venom was studied 24 h before and after the end of a rush venom immunotherapy protocol (7 days). The results were compared with 13 controls. An early significant decrease in skin reactivity was documented (p < 0.001), which was not related to an increase in specific IgG. Thus, rush venom immunotherapy induces a very early decrease in skin reactivity.

Abstract
Ten healthy donors and four patients with Diamond-Blackfan anemia (DBA) have been investigated for granulocyte-macrophage colony stimulating factor (GM-CSF) and stem cell factor (SCF) production by bone marrow-enriched fibroblasts (BMEF) in a highly sensitive biological assay on growth factor-dependent M-07e cells. M-07e cells detected active soluble kit-ligand from normal bone marrow fibroblasts as well as from DBA BMEF which produce constitutively significant amounts of SCF. Interleukin 1 beta (IL-1 beta) induced a significant increase of soluble SCF from both normal and DBA BMEF. GM-CSF was undetectable in unstimulated cultures, while its production by bone marrow microenvironmental cells was documented for both normal and DBA patients after IL-1 beta stimulation in vitro.

Abstract
The aim of this study was to test the in vitro cytokine production by peripheral blood mononuclear cells (PBMCs) in patients with Fanconi's anemia (FA). Phytohemagglutinin (PHA)-stimulated PBMCs from 21 patients with FA were studied for their ability to produce interleukin 6 (IL-6), leukemia inhibitory factor (LIF) and granulocyte-macrophage colony stimulating factor (GM-CSF). Enzymatic immunoassay (EIA) was used for both IL-6 and LIF, while GM-CSF was evaluated in a highly sensitive biological assay provided by GM-CSF-dependent M-07e cells. A significant decrease of IL-6 was detected in 9 out of 11 FA patients compared with five normal donors, while similar amounts of LIF were produced from 21 FA patients and 21 healthy subjects. A drastic increase of active GM-CSF was documented in PHA-stimulated PBMC-conditioned medium in all 18 FA patients tested. Since IL-6 and GM-CSF play an important role in maintaining basal hemopoiesis, our results suggest that an abnormal cytokine network may be involved in the pathogenesis of FA pancytopenia.

Abstract
The efficacy of an air-cleaning device equipped with a high efficiency particulate air (HEPA) filter (without further avoidance measures) was studied in patients allergic to house dust mite. The effects of the air-cleaner on indoor Dermatophagoides sp. levels, symptom score and bronchial hyperresponsiveness in nine mite-allergic patients were assessed using a cross-over controlled study. No significant effect was demonstrated on indoor Dermatophagoides sp. levels when comparing the period of air-cleaner activity (2 months) with the control period (2 months). The Dermatophagoides sp. levels in the houses studied were lower than the risk level for asthmatic attacks, making it difficult to assess any effect on asthma; however, neither bronchial hyperresponsiveness nor rhinitis symptom score were changed by air-cleaner activity. During the trial period, however the mean level of Dermatophagoides sp. allergen in the houses changed spontaneously from 4.4 micrograms/g (mean level in the first 2 trial months) to 1.75 micrograms/g of dust (second 2 months) (P less than 0.05). Owing to this change, the mean rhinitis symptom score also decreased (P less than 0.05), even if no significant correlation was demonstrated (r = 0.4 P = 0.089). HEPA filter air-cleaners appear insufficient as substitutes for standard avoidance measures in mite allergic patients.

Abstract
Thirty patients suffering from allergy to Parietaria pollen were treated with either a new tyrosine-adsorbed allergoid of Parietaria judaica pollen (Pollinex Parietaria) or a commercially available alum-adsorbed extract (Alavac) as control. A reduced response to nasal provocation was seen in 7 out of 11 patients following treatment with Pollinex and 1 out of 10 after control treatment. 9 out of 11 and 3 out of 10, respectively, showed reduced skin test activity. Patients who received Pollinex tended to have fewer nasal symptoms during the pollen season. Pollinex induced larger increases in P. judaica-specific IgG antibody than did the control product. Side effects of therapy were similar between the two groups of patients. Pollinex Parietaria thus shows good potential for the control of allergy to Parietaria pollen.

Abstract
In a double-blind crossover placebo controlled study, the inhibitory effects of three different doses of nedocromil sodium on the immediate bronchoconstrictor response to antigen challenge were compared with a placebo. All the test treatments were inhaled three hours before challenge. Four asthmatic patients took part in the study and the test treatments were taken in a randomized order. All three doses of nedocromil sodium significantly reduced the bronchoconstrictor response and protected the patients against antigen challenge, compared with placebo. The highest dose of 2 mg was the most effective dose. All test doses of nedocromil sodium were safe and well tolerated by the patients.

Abstract
The protective effect of sodium cromoglycate against the bronchospasm induced by exercise in 10 asthmatic subjects was compared with that of placebo in a single-blind study. The drug, which was administered by means of a metered dose aerosol, at a lower dose than is currently used in the therapy of asthma, was shown to be significantly more effective than placebo in preventing postexercise changes in all the respiratory function parameters measured (VC, FEV1, PEFR, MEFR50, TGV and SGaw).

Abstract
The anti-inflammatory, analgesic and tranquillizing activity of a synthetic compound called parsalmide was investigated in patients suffering from inflammatory and degenerative rheumatic arthropathies. The study was carried out in 30 subjects using the controlled experiment technique according to the "between patient" pattern, attributing parsalmide and indomethacin at random to two groups. Both preparations were found to possess good anti-inflammatory and analgesic action, comparable clinically and statistically. Tolerance was very good, particularly at gastroenteric level (no side and/or undesired effects were observed) and at the level of haemopoietic, renal and hepatic function.
