RESUMO
OBJECTIVES: To explore the negative predictive value (NPV) of C-reactive protein (CRP) at admission to exclude complicated disease manifestations of pneumococcal disease. METHODS: A Dutch multicentre retrospective cohort study was conducted between 01-01-2012 and 30-06-2020. Adults with positive blood cultures for Streptococcus pneumoniae, whose CRP was measured at admission and whose infection focus was known, were included. Electronic medical and microbiological records were reviewed. RESULTS: Of the 832 bacteraemic patients enrolled, 30% had complicated manifestations of pneumococcal disease; most frequent were pleural effusion (8.9%), pleural empyema (5.4%) and meningitis (7.5%). Compared to solitary pneumonia, patients with pleural effusion and empyema presented with higher CRP levels. Although low CRP levels did not exclude complicated disease in general, a CRP level < 114 mg/L at admission could reliably exclude empyema among adult pneumonia patients with an NPV of 93% and a specificity of 26%. However, in cases where pleural fluid was present, CRP levels were mostly > 114 mg/L, such that suspicion of empyema could only be ruled out in a minority of cases (10%). CONCLUSIONS: Complicated manifestations are prevalent in adult pneumococcal bacteraemia. Low blood CRP levels can reliably exclude the development of pulmonary empyema. Practical value may be largest in settings without thoracic imaging at hand.

PURPOSE OF REVIEW: Statins are associated with muscle complaints, including myositis. The mechanism through which statin use causes muscle toxicity is unknown. One of the theories is that statin therapy reduces coenzyme Q10 levels in muscle mitochondria, which leads to muscle injury and myopathy. The aim of the present article is to review published data on the association between coenzyme Q10 and statin-associated myopathy. RECENT FINDINGS: Studies have consistently shown that statins reduce coenzyme Q10 levels in serum and that supplementation of coenzyme Q10 increases these levels. However, the effect of statin therapy on coenzyme Q10 levels in muscle has been conflicting. Recently, two pilot studies on coenzyme Q10 supplementation in statin-induced myopathy and one study on the effect of coenzyme Q10 supplementation on serum muscle enzyme levels were published. These three studies were the first randomized trials with coenzyme Q10 supplementation in hypercholesterolemic patients treated with statins. The results of these trials have been contradictory; whereas one seems to support supplementation with coenzyme Q10, the other two do not. SUMMARY: This review summarizes the current evidence on coenzyme Q10 supplementation in statin-induced myopathy. We conclude that the present evidence does not support coenzyme Q10 supplementation in statin-induced myopathy.

OBJECTIVE: To assess the quality of hypertension care in patients with type 2 diabetes in general practice and identify physician, organizational, and patient factors associated with suboptimal care. RESEARCH DESIGN AND METHODS: Data from 895 randomly selected diabetic patients were extracted from the electronic medical records of 95 general practitioners. Physician and organizational characteristics were collected with a questionnaire. We conducted a multilevel analysis to identify associations with blood pressure registration, hypertension treatment, and achievement of target blood pressure levels. RESULTS: For 652 patients (73%), a blood pressure measurement was recorded in the last year. Of these patients, 132 (20%) reached a target level of 135/85 mmHg. In total, 595 patients were classified as having hypertension, of whom 192 received no treatment (32%), 193 received an ACE inhibitor (32%), and 210 received other antihypertensives. Patients visiting a diabetes facility, referred to a specialist, with a female general practitioner, or with a general practitioner with =10 years work experience had better recordings of their blood pressure. Suboptimal treatment was higher in older patients and smoking patients. Treatment was better in patients with coronary comorbidity, hyperlipidemia, or those referred to a specialist. Not achieving the blood pressure target was related to older age of the patients. CONCLUSIONS: Hypertension management of type 2 diabetic patients in primary care is suboptimal. Characteristics of general practitioners as well as additional care provided by a diabetes facility or a specialist are associated with better processes of care, but blood pressure outcomes are not as clearly related to these factors.
