Objective: To assess whether use of oral glucocorticoids is associated with cardiovascular and cerebrovascular morbidity. Design and setting: Nested case-control study within a cohort of patients (> 50 years old) with at least one prescription for oral or non-systemic glucocorticoids. Data were from the general practice research database. Patients: 50 656 patients were identified with a first record for ischaemic heart disease (International classification of diseases, ninth revision (ICD-9) codes 410, 411, 413, and 414), ischaemic stroke or transient ischaemic attack (ICD-9 codes 430-436), or heart failure (ICD-9 code 428) between 1988 and 1998. One control was matched to each case by sex, age, general practice, underlying disease, and calendar time. Main outcome measure: Odds ratio (OR) of cardiovascular or cerebrovascular events in patients using oral glucocorticoids compared with non-users.Results: There was a significant association between ever use of oral glucocorticoids and any cardiovascular or cerebrovascular outcome (adjusted OR 1.25, 95% confidence interval (CI) 1.21 to 1.29). The association was stronger for current use of oral glucocorticoids than for recent or past use. Among current users, the highest ORs were observed in the group with the highest average daily dose, although the dose-response relation was not continuous. Current use was associated with an increased risk of heart failure (adjusted OR 2.66, 95% CI 2.46 to 2.87), which was consistent between patients with rheumatoid arthritis, patients with chronic obstructive pulmonary disease, and patients without either of the two conditions. Also, current use was associated with a smaller increased risk of ischaemic heart disease (OR 1.20, 95% CI 1.11 to 1.29). Conclusions: Oral glucocorticoid use was identified as a risk factor for heart failure. However, the evidence remains observational and only a randomised controlled trial of glucocorticoid treatment versus other disease modifying agents is likely to distinguish the importance of the underlying disease activity from its treatment in predicting cardiovascular outcomes. G lucocorticoids are widely prescribed drugs in modern medicine. Data from the UK suggest that nearly 1% of the total adult population use oral glucocorticoids.

Use of antipsychotics in elderly people is associated with greater risk of pneumonia. This risk is highest shortly after the initiation of treatment, with the greatest increase in risk found for atypical antipsychotics.

SUMMARY BackgroundMicroscopic colitis (MC) is a chronic bowel disorder characterised by watery diarrhoea. Nonsteroidal anti-inflammatory drugs (NSAIDs), proton pump inhibitors (PPIs), selective serotonin reuptake inhibitors (SSRIs) and statins have been associated with MC. However, underlying mechanisms remain unclear.

Despite applying uniform methods, variations in the prevalence of antidepressant prescribing were obvious in the different populations. Database characteristics and clinical factors may both explain these variations.

Summary: Purpose:To compare the incidence of various fractures in a cohort of patients with epilepsy with a reference cohort of patients not having epilepsy.Methods: Patients were included in the epilepsy cohort if they had at least one diagnosis of epilepsy in their medical history and had sufficient evidence of "active" epilepsy (use of antiepileptic drugs, diagnoses) after the practice was included in the General Practice Research Database (GPRD). Two reference patients were sampled for each patient with epilepsy from the same practice. Primary outcome was the occurrence of any fracture during follow-up. Poisson regression analysis was used to estimate incidence density ratios (IDRs).Results: The study population comprised 40,485 and 80,970 patients in the epilepsy and reference cohorts, respectively. The median duration of follow-up was ∼3 years. The overall incidence rate in the epilepsy cohort was 241.9 per 10,000 personyears. This rate was about twice as high as that in reference cohort: age-and sex-adjusted IDR, 1.89 (95% CI, 1.81-1.98). When comparing IDRs among the different groups of fractures, the highest relative-risk estimate was found for hip and femur fractures (adjusted IDR, 2.79; 95% CI, 2.41-3.24). IDRs were consistently elevated across age and sex groups and across fracture subtypes.Conclusions: The overall risk of fractures was nearly twice as high among patients with epilepsy compared with the general population. The relative fracture risk was highest for hip and femur. Further study is necessary to elucidate whether this elevated risk is due to the disease, the use of antiepileptic drugs, or both.
