This study was carried out to determine whether serum cosinophil cationic protein (ECP) represents a sensitive marker for disease activity in atopic asthmatic patients during the pollen season. The study. in double‐blind fashion, was performed between February and June 1994. Two groups of 10 seasonal asthmatic patients randomly received two different treatments. The first group was treated with inhaled beclomethasone dipropionate (BDP) 500 kg bid; the second received a matched placebo (P). At the beginning and every month, blood samples for determination of ECP and eosinophil count were collected and lung function (FEV1) and methacholine responsiveness (PD20) were performed. Subjects recorded daily symptoms of asthma, salbutamol consumption, and peak expiratory flow (PEF) values. In the P group, all indices, except FEV1, showed significant changes during the pollen season (P< 0.001). In the BDP group, significant changes were detected for symptom score (P<0.01). salbutamol consumption (P<0.01), and eosinophil number (P<0.05). Between the two groups, significant differences for symptom score (P<0.001), salbutamol consumption (P< 0.001), ECP levels (P<0.05), eosinophil count (P<0.02), PD20 methacholine (P<0.02), and PEF values (P<0.01) were detected. Changes in serum ECP significantly correlated with changes in other parameters (P< 0.001), except FEV1. Our results provide evidence that serum ECP is a sensitive marker for monitoring of the disease activity in seasonal asthma. Furthermore, it may offer a useful tool for estimating treatment efficacy.

Most of the tuberculosis cases in Campania occur in Naples, the biggest city in the South of Italy with the highest unemployment and immigration rates. However, the occurrence of tuberculosis differs between the different neighbourhoods and it is not known whether these differences are associated with poverty or with immigration. We describe tuberculosis incidence and its association with socio-economic status and immigration in the city of Naples during the period 1996–2000. The basic design was an ecological study, correlating the incidence of tuberculosis which was calculated on the basis of notified tuberculosis cases to census data on immigration and socio-economic deprivation per neighbourhood. Immigrants had a high risk for tuberculosis (RR=34 for Africans) but the incidence of TB varied largely by districts and seemed independent of immigration. All socioeconomic factors increased the incidence of TB significantly. In a multivariate Poisson regression analysis only the rate of unemployment (p=0.02) and the population density (p=0.002) remained independently associated with tuberculosis incidence. In this study we showed that deprivation explained differences in tuberculosis incidence in Naples to a greater extent than immigration.

Patients with arthritis who need treatment with biologics are carefully screened for possible previous exposure to tuberculosis to detect any latent tubercular infection (LTBI). The traditional method of screening for LTBI is not specific, because positivity could also depend on infection by atypical mycobacteria and bacillus Calmette-Guerin vaccination. In addition, the screening does not show high sensitivity, frequently presenting a false negativity because of immunosuppression caused by drugs used for arthritis. Recently, interferon-γ release assays (IGRA) have been used to screen LTBI with more sensitivity and specificity before treatment with anti-tumor necrosis factor-α drugs. Moreover, in our experience, IGRA are potentially useful in monitoring LTBI during biologic therapy.

Background: The possibility that individual chronic obstructive pulmonary disease (COPD) patients respond better to either tiotropium or salmeterol has been suggested and an acute bronchodilator test might help to guide the choice of therapy. Objectives: We explored the responses to tiotropium and salmeterol within the first 3 h using the recommended dosages (18 µg for tiotropium and 50 µg for salmeterol) in order to verify whether there are differences in the short-term bronchodilator effects between these two long-acting bronchodilators in patients with stable COPD. Moreover, we investigated whether these differences could discriminate between the two agents. Methods: Forty consecutive patients with COPD, but in a stable phase of the disease, participated in this double-blind, double-dummy, randomized crossover study. The study involved a screening visit and 2 study days separated by at least 1 week. For determination of the onset of action, we measured FEV1 at 10, 20, 30, 60 and 90 min, and again 2 and 3 h after inhalation of single study drug. Results: At all time points, both tiotropium and salmeterol caused significant (p< 0.001) changes from baseline. A mean increase of 12% above baseline was reached 66 min (95% CI: 45–87) after tiotropium and 59 min (95% CI: 41–77) after salmeterol. Nine patients after tiotropium and 5 patients after salmeterol did not have this type of improvement. A mean increase of 200 ml above baseline was reached 76 min (95% CI: 52–101) after tiotropium and 76 min (95% CI: 52–100) after salmeterol. Eighteen patients after tiotropium and 15 patients after salmeterol did not have this improvement. Twenty-one patients after tiotropium and 24 patients after salmeterol reached an improvement that was at the same time 12% and 200 ml greater than baseline. Conclusions: These data clearly show that the bronchodilator effects of tiotropium and salmeterol within the first hours after their acute administration are similar in patients with stable COPD when they are evaluated as mean changes from baseline in FEV1. Therefore, they question the direct therapeutic relevance of a subdivision of patients according to bronchodilator responses to tiotropium or salmeterol.
