Immunomodulatory therapy to achieve maximum efficacy: doses, monitoring, compliance, and self-infusion at home

The Oxford Programme for Immunomodulatory Immunoglobulin Therapy has been operating since 1992 at Oxford Radcliffe Hospitals in the UK. Initially, this program was set up for patients with multifocal motor neuropathy or chronic inflammatory demyelinating poly-neuropathy to receive reduced doses of intravenous immunoglobulin (IVIG) in clinic on a regular basis (usually every 3 weeks). The program then rapidly expanded to include self-infusion at home, which monitoring showed to be safe and effective. It has been since extended to the treatment of other autoimmune diseases in which IVIG has been shown to be efficacious.

Reduction of inappropriate medications among older nursing-home residents: a nurse-led, pre/post-design, intervention study

Background: Medication-related problems are common in the growing population of older adults and inappropriate prescribing is a preventable risk factor. Explicit criteria such as the Beers criteria provide a valid instrument for describing the rate of inappropriate medication (IM) prescriptions among older adults. Objective: To reduce IM prescriptions based on explicit Beers criteria using a nurse-led intervention in a nursing-home (NH) setting. Study Design: The pre/post-design included IM assessment at study start (pre-intervention), a 4-month intervention period, IM assessment after the intervention period (post-intervention) and a further IM assessment at 1-year follow-up. Setting: 204-bed inpatient NH in Bern, Switzerland. Participants: NH residents aged ≥60 years. Intervention: The intervention included four key intervention elements: (i) adaptation of Beers criteria to the Swiss setting; (ii) IM identification; (iii) IM discontinuation; and (iv) staff training. Main Outcome Measure: IM prescription at study start, after the 4-month intervention period and at 1-year follow-up. Results: The mean±SD resident age was 80.3±8.8 years. Residents were prescribed a mean±SD 7.8±4.0 medications. The prescription rate of IMs decreased from 14.5% pre-intervention to 2.8% post-intervention (relative risk [RR] = 0.2; 95% CI 0.06, 0.5). The risk of IM prescription increased nonstatistically significantly in the 1-year follow-up period compared with post-intervention (RR = 1.6; 95% CI 0.5, 6.1). Conclusions: This intervention to reduce IM prescriptions based on explicit Beers criteria was feasible, easy to implement in an NH setting, and resulted in a substantial decrease in IMs. These results underscore the importance of involving nursing staff in the medication prescription process in a long-term care setting.

A randomized trial of effects of health risk appraisal combined with group sessions or home visits on preventive behaviors in older adults

Background. To explore effects of a health risk appraisal for older people (HRA-O) program with reinforcement, we conducted a randomized controlled trial in 21 general practices in Hamburg, Germany. Methods. Overall, 2,580 older patients of 14 general practitioners trained in reinforcing recommendations related to HRA-O-identified risk factors were randomized into intervention (n = 878) and control (n = 1,702) groups. Patients (n = 746) of seven additional matched general practitioners who did not receive this training served as a comparison group. Patients allocated to the intervention group, and their general practitioners, received computer-tailored written recommendations, and patients were offered the choice between interdisciplinary group sessions (geriatrician, physiotherapist, social worker, and nutritionist) and home visits (nurse). Results. Among the intervention group, 580 (66%) persons made use of personal reinforcement (group sessions: 503 [87%], home visits: 77 [13%]). At 1-year follow-up, persons in the intervention group had higher use of preventive services (eg, influenza vaccinations, adjusted odds ratio 1.7; 95% confidence interval 1.4–2.1) and more favorable health behavior (eg, high fruit/fiber intake, odds ratio 2.0; 95% confidence interval 1.6–2.6), as compared with controls. Comparisons between intervention and comparison group data revealed similar effects, suggesting that physician training alone had no effect. Subgroup analyses indicated favorable effects for HRA-O with personal reinforcement, but not for HRA-O without reinforcement. Conclusions. HRA-O combined with physician training and personal reinforcement had favorable effects on preventive care use and health behavior.

Dialysis and Renal Transplantation in HIV-Infected Patients: a European Survey

OBJECTIVES:: To determine prevalence and characteristics of end-stage renal diseases (ESRD) [dialysis and renal transplantation (RT)] among European HIV-infected patients. METHODS:: Cross-sectional multicenter survey of EuroSIDA clinics during 2008. RESULTS:: Prevalence of ESRD was 0.5%. Of 122 patients with ESRD 96 were on dialysis and 26 had received a RT. Median age was 47 years, 73% were males and 43% were black. Median duration of HIV infection was 11 years. Thirty-three percent had prior AIDS; 91% were receiving antiretrovirals; and 88% had undetectable viral load. Median CD4T-cell count was 341 cells per cubic millimetre; 20.5% had hepatitis C coinfection. Most frequent causes of ESRD were HIV-associated nephropathy (46%) and other glomerulonephritis (28%). Hemodialysis (93%) was the most common dialysis modality; 34% of patients were on the RT waiting list. A poor HIV control was the reason for exclusion from RT waiting list in 22.4% of cases. All the RT recipients were all alive at the time of the survey. Acute rejection was reported in 8 patients (30%). Functioning graft was present in 21 (80%). CONCLUSIONS:: This is the first multinational cross-sectional study of ESRD among European HIV population. Low prevalence of ESRD was found. Two-thirds of patients were excluded from RT for non-HIV/AIDS-related pathologies. Most patients had a functioning graft despite a high acute rejection rate.

Cardiometabolic effects in caregivers of nursing home placement and death of their spouse with Alzheimer's disease

To test the hypothesis that cardiometabolic risk is attenuated when caregivers are relieved of caregiving stress when the caregiving recipient transitions out of the home.

Arterial stiffness depends on serum ionized calcium levels during dialysis with regional citrate anticoagulation

Hemodynamic effects related to changes in serum ionized calcium (iCa) are difficult to determine during conventional hemodialysis (HD) using a fixed dialysate concentration of calcium. Regional citrate anticoagulation (RCA) allows the study of the effects of predefined iCa changes on arterial stiffness and blood pressure (BP) during a single dialysis session. In a crossover study, 15 patients with end-stage renal disease underwent two HD sessions with RCA. Each session was divided into two study phases in which iCa was titrated either to 0.8-1.0 mm or to 1.1-1.4 mm. The sequence of phases was randomly chosen and alternated for the second session. After reaching a stable iCa level, pulse wave velocity (PWV), arterial BP, and heart rate were measured. iCa levels were modified during sequence 1 (iCa low-high) from a predialysis baseline value of 1.15 ± 0.09 mm, first to 0.92 ± 0.05 mm (time point 1; P < 0.001 vs. baseline) and then to 1.18 ± 0.05 (time point 2; ns). During sequence 2 (iCa high-low), iCa levels were modified from 1.15 ± 0.12 mm first to 1.20 ± 0.05 mm (time point 1; ns vs. baseline) and then to 0.93 ± 0.03 (time point 2; P < 0.001). Assuming a basic linear repeated measures model, PWV was positively related to iCa levels (P < 0.03) independent of systolic or diastolic BP, heart rate, or ultrafiltration rate. PWV is closely related to acute changes in serum iCa levels in HD patients using RCA. RCA provides an interesting opportunity to study the effects of acute iCa changes during one dialysis procedure.
