The iatrogenic costs of NSAID therapy: A population study

Objective. To estimate the iatrogenic costs of nonsteroidal antiinflammatory drug (NSAID) treatment from the perspective of the Italian National Health Service. Methods. We conducted a retrospective cohort study using the primary and secondary care claims data registered in the regional health service database in the Friuli-Venezia Giulia (Italy). The study cohort comprised all persons (265,114) who received at least one prescription for any NSAID between August 1996 and July 1998. The outcomes of interest were the costs of medical interventions for upper gastrointestinal disorders following NSAID treatment (i.e., prescriptions for gastroprotective drugs, hospitalizations, and outpatient diagnostic procedures). Results. The study population received a total of 660,311 NSAID prescriptions for a cost of 6,587,533 Euros (ε) (ε0.53 per treatment day). The cost of medical interventions for gastrointestinal events added 58% to the cost of NSAID therapy (ε0.31 per NSAID treatment day, up to 64% directly attributable to NSAID use). The iatrogenic costs were generated by 12.4% of the patients, 77% of whom had a positive history of gastrointestinal disorders and 82% of whom were older than 50 years. Co-prescriptions for gastroprotective drugs accounted for 78.6% of the overall iatrogenic costs. The iatrogenic costs did not differ between cyclooxygenase (COX) nonselective and COX-2 preferential drugs within strata of age and prior history of gastrointestinal disorders, but were significantly higher for the parenteral NSAIDs than the oral or rectal formulations. Conclusions. In Italy, the iatrogenic costs of NSAID therapy add 58% to the cost of NSAID treatment; most of the cost is generated by co -prescriptions of gastroprotective drugs to elderly NSAID users or patients with a history of gastrointestinal disorders

Multispacer Sequence Typing Relapsing Fever Borreliae in Africa

In Africa, relapsing fevers are caused by four cultured species: Borrelia crocidurae, Borrelia duttonii, Borrelia hispanica and Borrelia recurrentis. These borreliae are transmitted by the bite of Ornithodoros soft ticks except for B. recurrentis which is transmitted by louse Pediculus humanus. They cause potentially undifferentiated fever infection and co-infection with malaria could also occur. The exact prevalence of each Borrelia is unknown and overlaps between B. duttonii and B. crocidurae have been reported. The lack of tools for genotyping these borreliae limits knowledge concerning their epidemiology. We developed multispacer sequence typing (MST) and applied it to blood specimens infected by B. recurrentis (30 specimens), B. duttonii (18 specimens) and B. crocidurae (13 specimens), delineating these 60 strains and the 3 type strains into 13 species-specific spacer types. B. crocidurae strains were classified into 8 spacer types, B. duttonii into 3 spacer types and B. recurrentis into 2 spacer types. These findings provide the proof-of-concept that that MST is a reliable tool for identification and genotyping relapsing fever borreliae in Africa

[Multicenter study on bronchopneumonia treated in a hospital environment in Friuli-Venezia Giulia: 2) Antibiotic therapy].

An analysis of a year's admissions for Pneumonia in all the Paediatric Department of the Region Friuli Venezia Giulia is presented. The study was conducted as activity of the Regional Section of the Italian Paediatric Society. The survey of the 14 Paediatric Centres produced a total of 536 cases of Pneumonia in the period January-December 1982 and was focused on antimicrobial therapy adopted pre and after hospitalization. General and specific therapeutic choices are discussed. Drawing the attention on the differences among centres

[Multicenter study on bronchopneumonia treated in a hospital environment in Friuli-Venezia Giulia: 1) Epidemiology].

Results are presented of a vast analysis into Bronchopneumonia (B.P.) conducted in North East Italy as activity of the Regional Section of the Italian Paediatric Society. The survey of the 14 Paediatric Centres in the Friuli Venezia Giulia Region, produced a total of 536 cases of B.P. in the period January-December 1982. Some significant connections between the several epidemiologic parameters investigated, with special interest in length of hospitalization, are commented. Bed occupancy, short vs. long stays, efficient management are discussed having also in consideration specific possible necessities of some local communities
