The Po River Delta epidemiological study: use of medicines in a general population sample of north Italy

Abstract

Purpose—To provide information on the actual use of medicines in a general population sample. Methods—Information was collected in a general population sample of North Italy (1946 subjects; 938 males, 1008 females) by an interviewer‐administered questionnaire. Results—Of the subjects 25.9% took habitually at least one medicine, whereas 11.1% used medicaments only occasionally. The use of medicines was significantly higher in females than in males (p < 0.001), but only in 15–44‐year‐old females, because of the use of oral contraceptives. The use of medicines increased with ageing (OR=1.80, p < 0.001). The highest use of habitual medicaments was found in subjects of 55+ years of both sexes. In both sexes, the medicines classified in the cardiovascular therapeutic group were the most frequently used. The use of gastrointestinal and cardiovascular medicines was significantly higher in males than in females (p < 0.001). In males, the use of habitual medicines was significantly (p < 0.001) higher in current smokers and ex‐smokers than in never smokers. Only 23% of allergic subjects used antiallergic medicines, and only 35% of subjects with respiratory symptoms/diseases used medicines classified into the bronchopulmonary therapeutic group. The percentage of subjects who reported cardiovascular symptoms/diseases and used medicines classified in the cardiovascular therapeutic group was greater (62%). Conclusions—We stress the importance of data collection in general population samples by questionnaires to investigate the actual use of medicines. This may give a more accurate estimate of medicine use than is possible from pharmacy sales or hospital records. Copyright © 2000 John Wiley & Sons, Ltd.

The significance of serum total immunoglobulin E for in vitro diagnosis of allergic rhinitis

“…A high tIgE level is very likely to be associated with AR and further in vitro testing should be able to identify specific allergens. Factors that can affect IgE levels, including the environment, location, age, and sex, did not affect our results. The number and type of allergens in symptomatic patients were not found to affect tIgE levels in this study as opposed to other reports …”

“…Measurement of tIgE has been used in clinical practice and investigated for its diagnostic role for allergic disorders such as rhinitis and asthma . However, secondary factors such as environment, location, age, sex, and smoking have also been implicated in affecting baseline tIgE levels. Furthermore, the true value measurement of tIgE levels is currently inconclusive because studies report considerable overlap of values between sensitized and nonsensitized individuals, whereas others report specific reference and/or diagnostic predictive values .…”

The Etiology of Different Forms of Urticaria in Childhood

“…Total IgE levels were greater than 45 kU/L in the majority of patients (74%) (9). There were no significant differences between those with acute, recurrent, or chronic urticaria concerning IgE levels (288.36 ± 87.22 versus 148.00 ± 48.09 versus 222.81 ± 70.18, respectively).…”

Pityriasis alba: Possible associations with intestinal helminths and pathogenic protozoa

“…11 Elevation of total serum IgE levels is also associated with parasitic infections (helminths), multiple myeloma and other diseases. [12][13][14] Helminths are powerful inducers of IgE responses, which are associated with protective immunity in human infections with Ankylostoma, Ascaris and Trichuris. However, how this response relates to allergy remains unclear.…”
