OBJECTIVES: Information on the impact of polypharmacy on kidney function in older adults is limited. We prospectively investigated the association between intake of total number of drugs or nonsteroidal anti-inflammatory drugs (NSAIDs) and kidney function. DESIGN: Our study is a prospective observational analysis of the 2-year Zurich Multiple Endpoint Vitamin D Trial in Knee Osteoarthritis Patients. SETTING AND PARTICIPANTS: Of the 273 participants of the original trial, 270 participants (mean age 70.3 ± 6.4 years, 53% women) were included in this observational analysis. METHODS: The associations between (1) total number of drugs (or NSAIDs) at baseline or (2) cumulative number of drugs (or NASAIDs) repeatedly measured over 24 months and kidney function repeatedly measured over 24 months as estimated glomerular filtration rate (eGFR) were investigated using multivariable-adjusted repeated-measures analysis. RESULTS: Per drug at baseline, kidney function decreased by 0.64 mL/min/1.73 m2 eGFR (Beta = -0.64; 95% CI -1.19 to -0.08; P = .024) over 24 months. With every additional drug taken cumulatively over 24 months, kidney function decreased by 0.39 mL/min/1.73 m2 eGFR (Beta = -0.39; 95% CI -0.63 to -0.15; P = .002). In a high-risk subgroup, per NSAID taken cumulatively over 24 months, kidney function declined by 1.21 mL/min/1.73 m2 eGFR (Beta = -1.21; 95% CI -2.35 to -0.07; P = .021). CONCLUSIONS AND IMPLICATIONS: For every additional drug prescribed among older adults, our study supports an independent and immediate harmful impact on kidney function. This negative impact seems to be about 3 times greater for NSAIDs compared with an additional average drug.

OBJECTIVES: To determine whether statin use alters response of 25-hydroxyvitamin D (25(OH)D) level to vitamin D treatment. DESIGN: Pooled analysis. SETTING: Three double-blind randomized controlled trials that tested different doses of vitamin D. PARTICIPANTS: Participants of three trials (N = 646; mean age 76.3 ± 8.4, 65% female). MEASUREMENTS: In all three trials, 25(OH)D status and statin use were assessed repeatedly over time (baseline, 6 and 12 months). Repeated-measures analysis was used to compare 25(OH)D response to vitamin D treatment at baseline and 6 and 12 months of statin users and nonusers, controlling for age, sex, body mass index, Charlson Comorbidity Index, vitamin D dose, trial, and season. RESULTS: At baseline, 17.5% were statin users, and 65% were vitamin D deficient (25(OH)D < 20 ng/mL). Baseline 25(OH)D levels did not differ significantly between groups at baseline (18.8 for statin users, 17.2 ng/mL for nonusers, P = .07), but according to the longitudinal analyses, the total increase over 12 months in 25(OH)D concentration was significantly lower in statin users (13.1 ng/L) than nonusers (15.9 ng/mL; 21.4% difference; P = .009). CONCLUSION: Of persons aged 60 and older at high risk of vitamin D deficiency, statin users had a 21.4% smaller increase in 25(OH)D serum concentrations over time than nonusers, independent of vitamin D dose and other covariates.

Due to incipient HELLP syndrome and no progression in labour, a caesarean was performed on a 33-year-old para I gravida I. During the operation she suffered a heavy blood loss as a result of uterine inertia. In the postoperative stage she developed an acute idiopathic colonic pseudo-obstruction, also known as Ogilvie's syndrome. Only 6 days after the operation did she slowly recover. Additional factors that could have led to Ogilvie's syndrome are the caesarean, the HELLP syndrome and the postpartal haemorrhage. Due to her reduced physical health, the mobilization of the patient was restricted, which further prolonged the recovery. However, an early initiation of supportive treatment, the timely diagnosis of Ogilvie's syndrome and two colonoscopic decompressions prevented a caecal rupture. After 3 weeks of hospitalization, the patient was discharged in good general health.
