Systemic lupus erythematosus: clinical manifestations and immunological parameters in 194 patients. Subgroup classification of SLE.

We analysed the prevalence of clinical manifestations and immunological parameters in 194 patients with SLE and classified them in subgroups according to age at onset, gender and type of antibodies: we detected significant differences in the various subgroups. In SLE that initiated before the age of 20 years, the most frequent manifestation at onset was malar rash (25% vs 14%). During the course of the disease, this group had a greater prevalence of malar rash (70% vs 45%), mouth ulcers (48% vs 29%), and convulsions or psychosis (35% vs. 17%). In SLE that initiated late in life (after 50 years) malar rash was less frequent at onset and during subsequent evolution of the disease (27% vs 45%). The existence of ANA, and elevated values of anti-dsDNA, anti-ENA and antiphospholipid antibodies also differentiated the SLE subgroups with clinical significance.

Single dose pharmacokinetics of fenspiride hydrochloride: phase I clinical trial.

The absolute bioavailability of fenspiride has been studied in twelve healthy volunteers. It was administered IV and orally in single doses of 80 mg fenspiride hydrochloride according to a randomised crossover pattern. Following IV administration, the plasma clearance of fenspiride was about 184 ml.min-1, and its apparent volume of distribution was moderately large (215 l). When given orally as a tablet, fenspiride exhibited fairly slow ab- sorption; the maximum plasma concentration (206 ng.ml-1) was achieved 6 h after administration. The absolute bioavailability was almost complete (90%). The tablet had slow release characteristics. The elimination half-life obtained from the plasma data was 14 to 16 h independent of the route of administration.
