Objective:To investigate whether admission hyperglycemia predicts poststroke infections and, if so, whether poststroke infections modify the effect of admission hyperglycemia on functional outcome in ischemic stroke.Methods:We used data from acute ischemic stroke patients in the Preventive Antibiotics in Stroke Study (PASS), a multicenter randomized controlled trial (n = 2,550) investigating the effect of preventive antibiotics on functional outcome. Admission hyperglycemia was defined as blood glucose ≥7.8 mmol/L and poststroke infection as any infection during admission judged by an expert adjudication committee. Functional outcome at 3 months was assessed with the modified Rankin Scale.Results:Of 1,676 nondiabetic ischemic stroke patients, 338 (20%) had admission hyperglycemia. After adjustment for potential confounding variables, admission hyperglycemia was associated with poststroke infection (adjusted odds ratio [aOR] 2.31, 95% CI 1.31–4.07), worse 3-month functional outcome (common aOR 1.40, 95% CI 1.12–1.73), and 3-month mortality (aOR 2.11, 95% CI 1.40–3.19). Additional adjustment for poststroke infection in the functional outcome analysis, done to assess poststroke infection as an intermediate in the pathway from admission hyperglycemia to functional outcome, did not substantially change the model. In patients with recorded diabetes mellitus (n = 418), admission hyperglycemia was not associated with poststroke infection (aOR 0.49, 95% CI 0.15–1.58).Conclusions:In nondiabetic acute ischemic stroke patients, admission hyperglycemia is associated with poststroke infection and worse functional outcome. Poststroke infections did not modify the effect of admission hyperglycemia on functional outcome in ischemic stroke.

Item does not contain fulltext BACKGROUND: In adults with acute stroke, infections occur commonly and are associated with an unfavourable functional outcome. In the Preventive Antibiotics in Stroke Study (PASS) we aimed to establish whether or not preventive antimicrobial therapy with a third-generation cephalosporin, ceftriaxone, improves functional outcome in patients with acute stroke. METHODS: In this multicentre, randomised, open-label trial with masked endpoint assessment, patients with acute stroke were randomly assigned to intravenous ceftriaxone at a dose of 2 g, given every 24 h intravenously for 4 days, in addition to stroke unit care, or standard stroke unit care without preventive antimicrobial therapy; assignments were made within 24 h after symptom onset. The primary endpoint was functional outcome at 3 months, defined according to the modified Rankin Scale and analysed by intention to treat. The primary analysis was by ordinal regression of the primary outcome. Secondary outcomes included death, infection rates, antimicrobial use, and length of hospital stay. Participants and caregivers were aware of treatment allocation but assessors of outcome were masked to group assignment. This trial is registered with controlled-trials.com, number ISRCTN66140176. FINDINGS: Between July 6, 2010, and March 23, 2014, a total of 2550 patients from 30 sites in the Netherlands, including academic and non-academic medical centres, were randomly assigned to the two treatment groups: 1275 patients to ceftriaxone and 1275 patients to standard treatment (control group). 12 patients (seven in the ceftriaxone group and five in the control group) withdrew consent immediately after randomisation, leaving 2538 patients available for the intention-to-treat-analysis (1268 in the ceftriaxone group and 1270 in the control group). 2514 (99%) of 2538 patients (1257 in each group) completed 3-month follow-up. Preventive ceftriaxone did not affect the distribution of functional outcome scores on the modified Rankin Scale at 3 months (adjusted common odds ratio 0.95 [95% CI 0.82-1.09], p=0.46). Preventive ceftriaxone did not result in an increased occurrence of adverse events. Overgrowth infection with Clostridium difficile occurred in two patients (

The article by Schmidt and colleagues (2006) reported neuropsychological sequelae of bacterial and viral meningitis. In a retrospective study, they carefully selected patients and excluded those with concomitant conditions such as alcoholism after Streptococcus pneumoniae meningitis (Schmidt et al., 2006). The authors should be complimented for their solid work; however, some questions can be raised.

A 51-year-old man presented with a 6-week history of progressive headache, confusion and ataxic gate. The symptoms were not preceded by trauma or lumbar puncture. A CT-scan of the brain revealed bilateral subdural fluid accumulation and hyperdensities in the subarachnoid space. In view of the signs of a subarachnoid haemorrhage, angiography was performed but showed no indications of an aneurysm. An MRI-scan of the head revealed abnormalities in line with intracranial hypotension. CT-myelography of the whole spine revealed a cerebrospinal fluid leak at the level of the fifth and sixth thoracic vertebrae. The patient recovered completely after placement of an epidural blood patch at this level. Spontaneous intracranial hypotension shows clinical similarities with the symptoms following a lumbar puncture. In most cases it can be treated by conservative measures. However, invasive measures are sometimes necessary to close the defect in the meninges
