After 10 yr, a high proportion of patients in our cohort continued to show evidence of active disease, defined by the SLEDAI as well as ECLAM. The DI was related to the involvement of the central nervous system, renal involvement and the presence of hypertension.

A high proportion of patients in our cohort defined on clinical grounds as having incomplete SLE eventually showed disease activity defined by the SLEDAI as well as ECLAM. However, only three cases developed to SLE during the follow-up. This suggests that incomplete SLE forms a subgroup of SLE that has a good prognosis.

This prospective study compared the clinical and socio-economic impact of laboratory-confirmed influenza and respiratory syncytial virus (RSV) infection on healthy children and their families. Among 1,520 otherwise healthy children aged< 15 years attending the Emergency Department for acute conditions other than trauma, influenza viruses and RSV were found in 234 (15.4%) and 116 (7.6%; p<0.0001) patients, respectively. The fact that influenza has a similar global clinical impact on the community to that of RSV infection, but represents a greater socio-economic burden, may contribute to broadening the acceptance of influenza vaccination.

Data related to the disease course of patients with systemic lupus erythematosus (SLE) with special attention to the persistence of disease activity in the long term are scarce. At this moment reliable figures are only known about the survival rate as a measure of outcome. The aim of this multicenter study was to describe the outcome of SLE patients with a disease duration of greater than 10 y. Outcome parameters were two disease activity-scoring systems (SLEDAI and ECLAM), the end organ damage (SLICC/ACR damage index) and treatment. Our results are derived from 187 SLE patients followed at 10 different centres in Europe over a period of 1 y. Serious clinical signs or exacerbations, defined by the occurrence or detoriation of already existing symptoms of renal and cerebral nervous systems were observed in 2-11% of the patients, seizures and psychosis in 3%, proteinuria in 11% and an increase in serum creatinine in 5% of the patients. No change took place in the overall damage index. Yet, the disease course in most patients was characterized by periods of tiredness (42-60%), arthritis (20-25%), skin involvement such as malar rash (32-40%), migraine (15-20%), anaemia (15%) and leucopenia (17-19%). Summarizing these results it is shown that patients, still under care after such a long time of having this disease, do have a disease that is far from extinguished.

In patients with early RA, CsA + MTX combination therapy led to a significantly lower rate of 12-month radiographic progression, was effective on inflammatory articular symptoms, and was well tolerated.

In order to evaluate the efficacy of macrolides in pediatric patients with recurrent respiratory tract infections (RRTIs), we enrolled 1,706 children (783 females) aged between 6 months and 14 years (median: 4 years) with an acute respiratory infection and a history of RRTIs (> or = 8 episodes per year if aged < 3 years; > or = 6 episodes per year if aged > or = 3 years). The therapies were chosen by the primary care pediatricians and their effects on respiratory relapses were blindly analyzed. Regardless of age and clinical diagnosis, the children treated with macrolides showed a significantly higher rate of short- and long-term clinical success than those receiving beta-lactams (p<0.0001) or symptomatics alone (p<0.0001). These data show that macrolide therapy of acute respiratory infections influences the natural history of RRTIs, probably because of their elective activity on atypical bacteria. They also suggest the possible importance of these pathogens in causing recurrences of respiratory infections in children and show that the infections they cause may have a more complicated course unless treated with adequate antibacterial drugs.
