Cyclosporine dose reduction in stable renal transplant patients with high C2 level: simplified method of single C2 measurement and individualization of C0 target.

It is recommended that cyclosporine dosing should be based on the whole blood level 2 h after a dose (C2), not the trough level (C0). Initial studies did not however establish the outcome of dosing according to C2 levels in long-term patients previously managed by C0 levels. C0 and C2 were measured in 152 stable patients receiving Neoral therapy, mean 86.9 months after transplantation. This showed that 38 (25%) had C2 levels above a target range of 700-900 microg/l. Higher C2 levels were associated with higher cholesterol levels (P = 0.0058) and higher diastolic blood pressure (P = 0.0163). Cyclosporine dose reduction was undertaken in 32 patients with high C2 levels. For logistical reasons, C2 was not performed regularly, but an individualized C0 level was set for each patient. A 16% reduction in mean cyclosporine dose was achieved, associated with a 28% fall in mean C0, from 212 to 153 microg/l, and a 25% fall in mean C2, from 1075 to 820 microg/l. There was no excess in adverse events in the dose reduction cohort, compared with patients with initial C2 levels <900 microg/l. Over a mean 15 month follow-up period in the dose reduction cohort, there was a 4.4% reduction in mean diastolic blood pressure, from 84.9 (SEM 2.1) to 80.2 (1.9) mmHg, P = 0.023; and a 10.4% reduction in mean cholesterol, from 5.71 (0.27) to 5.11 (0.25), P = 0.005 (patients starting on statin during follow-up excluded). In patients with initial C2 <900 microg/l, blood pressure did not fall and the cholesterol fell by 3.9%, from 5.27 (0.14) to 5.07 (0.15) mmol/l (P = 0.0405). In conclusion, cyclosporine dose reduction was safe in stable long-term renal allograft recipients with high C2 levels. There was an improvement cholesterol levels and a small improvement in blood pressure after cyclosporine dose reduction.

Chlamydia--inside out.

The aim was to inform other health care professionals within the field of sexual health about the expanding role of the health adviser in genitourinary medicine. It also highlights the complementary role of a community health adviser that may develop if the chlamydia pilot study became a national screening programme. An audit of time management and workload created by partner notification for the positive patients generated by the chlamydia pilot was undertaken. This was done prospectively over a two-month period and the data were collected by the health advisers in the genitourinary medicine department. The results showed that 164 people generated by the pilot study were treated for chlamydia (80 cases and 84 partners): 25 letters and 8 phone calls were required to achieve this. The national sexual health strategy now addresses the issue of integration of sexual health services. It may be suggested that the role of the health adviser could be fundamental to this strategy and development of a community health adviser may then evolve.
