ABSTRACT
BACKGROUND: Previously, mainly retrospective and a few important prospective studies postulated the role of sepsis or systemic inflammatory response syndrome (SIRS), multiple organ failure, and the use of medication as causative factors for the development of critical illness polyneuropathy and myopathy (CIPNM). This study aimed to identify the risk factors in the development of CIPNM. METHODS: Prospectively, we studied 98 patients who were on artificial respirators for the development of CIPNM. The Acute Physiology and Chronic Health Evaluation (APACHE) III score, presence of SIRS, and sepsis severity score at entry; the dosage of midazolam, vecuronium, and steroids at entry and day 7 of artificial respiration; and the use of aminoglycosides at entry were related with time to CIPNM or time of last follow-up. The Kaplan-Meier method and log-rank test were used. RESULTS: Thirty-two patients (33%) developed CIPNM. After multivariate analysis, it was found that the APACHE III score and the presence of SIRS were significantly related with risk for the development of CIPNM. No significant relation was found for the use of midazolam, vecuronium, or steroids. Based on a risk index from a Cox regression model with APACHE III score and presence of SIRS as outcomes, three groups could be constructed with low-, medium-, and high-risk patients for the development of CIPNM. CONCLUSIONS: The APACHE III score, a quantitative index of disease severity based on clinical and laboratory physiologic data, is a valuable predictor for the development of CIPNM in patients in the intensive care unit. Together with the presence of SIRS, it can be used to estimate the risk of developing CIPNM for patients on artificial respirators.

We studied pregnancy outcome in preconceptionally recruited epileptic and control women in a multi-centre prospective non-intervention study at two university hospitals and three general hospitals. We evaluated 225 singleton pregnancies: 119 pregnancies of epileptic women who received either antiepileptic drugs (AEDs) (n = 99) or not (n = 20), and 106 pregnancies of controls. The main outcome measures were abnormal pregnancy outcome: major and minor congenital malformations, ectopic pregnancies, abortions; neonatal headcircumference; birth weight and birth length. Epileptic women had a two-fold risk of having an abnormal pregnancy outcome or an infant with minor malformations compared to healthy controls (odds ratio, with 95% confidence interval, respectively 2.1 (1.1, 4.0) and 2.0 (1.0, 4.0)). A significant correlation between the prevalence of abnormal pregnancy outcome and duration of epilepsy and AED treatment was found (risk increased by 9% (6%, 16%) per annum). No significant effect in terms of the type, the number or the serum level of the AEDs could be established. The head circumference of infants of epileptic mothers was significantly smaller (0.7 (1.2, 0.28 cm) compared to controls. An effect on the outcome of pregnancy of maternal folate supplementation or of folate blood concentrations during the periconceptional period and first trimester of pregnancy could not be determined. The severity of maternal epilepsy and/or AED treatment influences pregnancy outcome.
