Valproic Acid-Associated Acute Pancreatitis: Systematic Literature Review.
Long-term medication with valproic acid has been associated with acute pancreatitis. The purpose of this report is to gain insight into the features of this pancreatitis. A preregistered literature search (CRD42023438294) was performed on the National Library of Medicine, Excerpta Medica, Web of Science, and Google Scholar. Patients with alcohol abuse disorder, gallstone disease, hypertriglyceridemia or hypercalcemia, patients with acute valproic acid intoxication, and patients with a pre-existing pancreatitis were excluded. For the final analysis, we retained 73 reports published between 1979 and 2023, which described 125 subjects (83 children and 42 adults predominantly affected by an epilepsy) with an acute pancreatitis related to valproic acid. The diagnosis was made 11 (3.0-24) months (median and interquartile range) after starting valproic acid. One hundred and five cases (84%) recovered and twenty (16%) died. Sex, age, dosage or circulating level of valproic acid, latency time, prevalence of intellectual disability, and antiepileptic co-medication were similar in cases with and without a lethal outcome. Nineteen subjects were rechallenged with valproic acid after recovery: sixteen (84%) cases developed a further episode of pancreatitis. In conclusion, pancreatitis associated with valproic acid presents at any time during treatment and has a high fatality rate
Baseline characteristics and outcome of stroke patients after endovascular therapy according to previous symptomatic vascular disease and sex
AimThe aim of this study was to investigate baseline characteristics and outcome of patients after endovascular therapy (EVT) for acute large vessel occlusion (LVO) in relation to their history of symptomatic vascular disease and sex.MethodsConsecutive EVT-eligible patients with LVO in the anterior circulation admitted to our stroke center between 04/2015 and 04/2020 were included in this observational cohort study. All patients were treated according to a standardized acute ischaemic stroke (AIS) protocol. Baseline characteristics and successful reperfusion, recurrent/progressive in-hospital ischaemic stroke, symptomatic in-hospital intracranial hemorrhage, death at discharge and at 3 months, and functional outcome at 3 months were analyzed according to previous symptomatic vascular disease and sex.Results995 patients with LVO in the anterior circulation (49.4% women, median age 76 years, median admission NIHSS score 14) were included. Patients with multiple vs. no previous vascular events showed higher mortality at discharge (20% vs. 9.3%, age/sex − adjustedOR = 1.43, p = 0.030) and less independency at 3 months (28.8% vs. 48.8%, age/sex − adjustedOR = 0.72, p = 0.020). All patients and men alone with one or multiple vs. patients and men with no previous vascular events showed more recurrent/progressive in-hospital ischaemic strokes (19.9% vs. 6.4% in all patients, age/sex − adjustedOR = 1.76, p = 0.028) (16.7% vs. 5.8% in men, age-adjustedOR = 2.20, p = 0.035). Men vs. women showed more in-hospital symptomatic intracranial hemorrhage among patients with one or multiple vs. no previous vascular events (23.7% vs. 6.6% in men and 15.4% vs. 5.5% in women, OR = 2.32, p = 0.035/age − adjustedOR = 2.36, p = 0.035).ConclusionsPrevious vascular events increased the risk of in-hospital complications and poorer outcome in the analyzed patients with EVT-eligible LVO-AIS. Our findings may support risk assessment in these stroke patients and could contribute to the design of future studies
Could infarct location predict the long-term functional outcome in childhood arterial ischemic stroke?
Serum neurofilament light chain in patients with acute cerebrovascular events
BACKGROUND AND PURPOSE Serum neurofilaments are markers of axonal injury. We addressed their diagnostic and prognostic role in acute ischemic stroke (AIS) and transient ischemic attack (TIA).
METHODS Nested within a prospective cohort study, we compared levels of serum neurofilament light chain (sNfL) drawn within 24 h from symptom onset in patients with AIS or TIA. Patients without magnetic resonance imaging on admission were excluded. We assessed whether sNfL was associated with: (i) clinical severity on admission, (ii) diagnosis of AIS vs. TIA, (iii) infarct size on admission magnetic resonance diffusion-weighted imaging (MR-DWI) and (iv) functional outcome at 3 months.
RESULTS We analyzed 504 patients with AIS and 111 patients with TIA. On admission, higher National Institutes of Health Stroke Scale (NIHSS) scores were associated with higher sNfL: NIHSS score 15, 21.0 pg/mL (IQR, 9.3-40.4) (P = 0.01). Compared with AIS, patients with TIA had lower sNfL levels [9.0 pg/mL (95% confidence interval, 4.0-19.0) vs. 16.0 pg/mL (95% confidence interval, 7.3-34.4), P < 0.001], also after adjusting for age and NIHSS score (P = 0.006). Among patients with AIS, infarct size on admission MR-DWI was not associated with sNfL, either in univariate analysis (P = 0.15) or after adjusting for age and NIHSS score on admission (P = 0.56). Functional outcome 3 months after stroke was not associated with sNfL after adjusting for established predictors.
CONCLUSIONS In conclusion, among patients admitted within 24 h of AIS or TIA onset, admission sNfL levels were associated with clinical severity on admission and TIA diagnosis, but not with infarct size on MR-DWI acquired on admission or functional outcome at 3 months
Neurological complications of rotavirus infection in children: A systematic review and meta-analysis.
To systematically review the clinical features and outcomes of paediatric patients developing neurological complications associated with a rotavirus infection.
A systematic literature review and meta-analysis was performed, including articles published from 1984 to 2020. Neurological complications were classified into four groups: encephalitis, cerebellitis, encephalo-cerebellitis and benign convulsions with mild gastroenteritis (CwG).
Out of 68 reports that fulfilled the research criteria, 99 cases of CwG, 39 cases of encephalitis, 18 cases of encephalo-cerebellitis and five cases of cerebellitis were collected. Ninety-five patients were from Asia. Median age was 22 (IQR 14-29) months, and the children who developed CwG were significantly younger (19, IQR 12-24 months, p < 0.0001) than the others. Status epilepticus was observed in 23% and 5% of the encephalitis and CwG groups respectively. The most frequently described neuroimaging finding were lesions of the splenium of corpus callosum. Four deaths were reported in the encephalitis group, whereas no fatal events were described in the other groups. Among the surviving children, the encephalo-cerebellitis group showed the most severe long-term outcome. All cases of CwG recovered completely.
Older age at diagnosis and the development of encephalo-cerebellitis are associated with a higher risk of long-term complications
Neurological complications of rotavirus infection in children: a systematic review and meta-analysis.
AIM
To systematically review the clinical features and outcomes of pediatric patients developing neurological complications associated with a rotavirus infection.
METHODS
A systematic literature review and meta-analysis was performed, including articles published from 1984 to 2020. Neurological complications were classified into four groups: encephalitis, cerebellitis, encephalo-cerebellitis and benign convulsions with mild gastroenteritis (CwG).
RESULTS
Out of 68 reports that fulfilled the research criteria, 99 cases of CwG, 39 cases of encephalitis, 18 cases of encephalo-cerebellitis and five cases of cerebellitis were collected. Ninety-five patients were from Asia. Median age was 22 (IQR 14-29) months, and the children who developed CwG were significantly younger (19, IQR 12-24 months, p<0.0001) than the others. Status epilepticus was observed in 23% and 5% of the encephalitis and CwG groups, respectively. The most frequently described neuroimaging finding were lesions of the splenium of corpus callosum. Four deaths were reported in the encephalitis group, whereas no fatal events were described in the other groups. Among the surviving children, the encephalo-cerebellitis group showed the most severe long-term outcome. All cases of CwG recovered completely.
CONCLUSION
Older age at diagnosis and the development of encephalo-cerebellitis are associated with a higher risk of long-term complications
Metabolic disturbances and renal stone promotion on treatment with topiramate: A systematic review
Aims The use of topiramate, which is prescribed for the management of epilepsy, for migraine headache prophylaxis and as a weight-loss agent, has been associated with the development of metabolic acidosis, hypokalaemia and renal stone disease. We systematically reviewed all the literature. Methods The systematic review of the literature was realized using the principles underlying the UK Economic and Social Research Council guidance on the conduct of narrative synthesis and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. Results Fourty-seven reports published between 1996 and 2013 were retained for the final analysis. Five case-control studies and six longitudinal studies addressed the effect of topiramate on acid-base and potassium balance. A significant tendency towards mild-to-moderate hyperchloraemic metabolic acidosis (with bicarbonate ≤21.0 mmol l -1 in approximately every third case) and mild hypokalaemia (with potassium ≤3.5 mmol l-1 in 10% of the cases) was noted on treatment with topiramate, which was similar in children and adults. A single study observed that topiramate causes mild hyperuricaemia in male adults. A tendency towards hypocitraturia, a recognized promoter of renal stone formation, was noted in all patients on topiramate. Conclusions Increasing evidence supports the use of topiramate. Topiramate is generally well tolerated, and serious adverse events are rare. Nonetheless, the present systematic review of the literature indicates that its use is linked with the development of acidosis, hypokalaemia, hyperuricaemia and hypocitraturia. © 2013 The British Pharmacological Society
