Guidelines on the insertion and management of central venous access devices in adults

Abstract: Central venous access devices are used in many branched of medicine where venous access is required for either long-term or a short-term care. These guidelines review the types of access devices available and make a number of major recommendations. Their respective advantages and disadvantages in various clinical settings are outlined. Patient care prior to, and immediately following insertion is discussed in the context of possible complications and how these are best avoided. There is a section addressing long-term care of in-dwelling devices. Techniques of insertion and removal are reviewed and management of the problems which are most likely to occur following insertion including infection, misplacement and thrombosis are discussed. Care of patients with coagulopathies is addressed and there is a section addressing catheter-related problems.

Growth hormone treatment improves serum lipids and lipoproteins in adults with growth hormone deficiency.

Abstract: The effects of 6 months' treatment with recombinant human growth hormone (rhGH) on serum lipids and lipoproteins were assessed in 24 adult patients with GH deficiency in a double-blind, placebo-controlled trial. Compared with age-, weight-, and sex-matched controls, the patients had significantly higher serum concentrations of total cholesterol (P = .002), low-density lipoprotein (LDL) cholesterol (P < .001), apolipoprotein B ([apoB] P = .011), and triglyceride (P = .017), and lower concentrations of high-density lipoprotein (HDL) cholesterol (P < .001). The prevalence of elevated serum cholesterol, triglyceride, LDL cholesterol, and apo B levels was 39%, 26%, 39%, and 25%, respectively; 75% of patients had decreased concentrations of HDL cholesterol. Treatment with rhGH (0.07 U/kg daily) resulted in decreases in total cholesterol level (5.8 +/- 0.3 to 5.1 +/- 0.3 mmol.L-1 over 6 months; P = .01 compared with placebo), LDL cholesterol level (4.22 +/- 0.25 to 3.19 +/- 0.23 mmol.L-1; P = .0003), LDL:HDL cholesterol ratio (5.57 +/- 0.47 to 3.29 +/- 0.33; P = .03), apo B level (1.07 +/- 0.06 to 0.84 +/- 0.07 g.L-1; P = .003), and apo B: A-1 ratio (0.73 +/- 0.05 to 0.69 +/- 0.05; P = .01). HDL cholesterol and apo A-1 levels did not change following rhGH treatment. The changes in lipid and lipoprotein levels were not significantly related to changes in insulin, thyroid hormones, insulin-like growth factor-1 (IGF-1), or indices of adiposity.(ABSTRACT TRUNCATED AT 250 WORDS)

Effect of belimumab treatment on renal outcomes: results from the phase 3 belimumab clinical trials in patients with SLE

Abstract: A pooled post-hoc analysis of the phase 3, randomized, placebo-controlled BLISS trials (1684 patients with active systemic lupus erythematosus (SLE)) was performed to evaluate the effect of belimumab on renal parameters in patients with renal involvement at baseline, and to explore whether belimumab offered additional renal benefit to patients receiving mycophenolate mofetil at baseline. In addition to belimumab or placebo, all patients received standard SLE therapy. Patients with severe active lupus nephritis were excluded from the trials. Over 52 weeks, rates of renal flare, renal remission, renal organ disease improvement (assessed by Safety of Estrogens in Lupus Erythematosus National Assessment-Systemic Lupus Erythematosus Disease Activity Index and British Isles Lupus Assessment Group), proteinuria reduction, grade 3/4 proteinuria, and serologic activity favored belimumab, although the between-group differences in most renal outcomes were not significant. Among the 267 patients with renal involvement at baseline, those receiving mycophenolate mofetil or with serologic activity at baseline had greater renal organ disease improvement with belimumab than with placebo. Limitations of this analysis included the small patient numbers and the post-hoc nature of this pooled analysis. The results suggest that belimumab may offer renal benefit in patients with SLE. Further study is warranted in patients with severe active lupus nephritis.

Effects of long‐term strontium ranelate treatment on the risk of nonvertebral and vertebral fractures in postmenopausal osteoporosis: Results of a five‐year, randomized, placebo‐controlled trial

Abstract: Objective This study was undertaken to assess the effect of strontium ranelate on nonvertebral and vertebral fractures in postmenopausal women with osteoporosis in a 5-year, double-blind, placebo-controlled trial. Methods A total of 5,091 postmenopausal women with osteoporosis were randomized to receive either strontium ranelate at 2 gm/day or placebo for 5 years. The main efficacy criterion was the incidence of nonvertebral fractures. In addition, incidence of hip fractures was assessed, by post hoc analysis, in the subset of 1,128 patients who were at high risk of fractures (age 74 years or older with lumbar spine and femoral neck bone mineral density T scores −2.4 or less). The incidence of new vertebral fractures was assessed, using the semiquantitative method described by Genant, in the 3,646 patients in whom spinal radiography (a nonmandatory procedure) was performed during the course of the study. Fracture data were analyzed using the Kaplan-Meier survival method. Results Of the 5,091 patients, 2,714 (53%) completed the study up to 5 years. The risk of nonvertebral fracture was reduced by 15% in the strontium ranelate group compared with the placebo group (relative risk 0.85 [95% confidence interval 0.73–0.99]). The risk of hip fracture was decreased by 43% (relative risk 0.57 [95% confidence interval 0.33–0.97]), and the risk of vertebral fracture was decreased by 24% (relative risk 0.76 [95% CI 0.65–0.88]) in the strontium ranelate group. After 5 years, the safety profile of strontium ranelate remained unchanged compared with the 3-year findings. Conclusion Our findings indicate that treatment of postmenopausal osteoporosis with strontium ranelate results in a sustained reduction in the incidence of osteoporotic nonvertebral fractures, including hip fractures, and vertebral fractures over 5 years.
