After two-dimensional gel electrophoresis (2D-PAGE), followed by Coomassie-blue staining, GS separated into three distinct spots (S1, S2, S3). One additional spot (S4) occurred on the immunoblot. All four GS spots exhibited the same Mr (44 000 Da), but differed in their isoelectric points. Densitometric evaluation of the two-dimensional maps revealed a strong increase of optical density (OD) of S3 in the frontal cortex of infected animals. The calculated OD ratio S3/S2 in the frontal cortex from rabbits with meningitis was 1.75±0.68 (mean±standard deviation). Compared to controls (0.85±0.39), this value was significantly increased (p=0.0006). In the hippocampal formation, the ratio S3/S2 was nearly unchanged during meningitis.

For this reason, we studied the relationship between glutamine synthetase activity and regional neuronal apoptosis in rabbits with experimental pneumococcal meningitis. The duration of meningitis was 24 h, and the treatment was started 16 h after infection. Significant increases of glutamine synthetase protein concentration (P < 0.05) were found in the frontal cortex of rabbits with meningitis (n = 7) and rabbits with meningitis receiving ceftriaxone treatment (n = 12) as compared to the control animals (n = 14). No significant differences were seen in the hippocampal formation. The enzymatic activity of glutamine synthetase also was elevated in the frontal cortex (P < 0.05), but not in the hippocampal formation of rabbits with meningitis. After intravenous administration of L-methionine sulfoximine (specific inhibitor of glutamine synthetase) in rabbits with meningitis treated with ceftriaxone (n = 10), the concentration of neuron-specific enolase in CSF (P = 0.025) and the density of apoptotic neurons in the dentate gyrus quantified with the in-situ tailing reaction (P = 0.043) were higher than in meningitic animals receiving only ceftriaxone (n = 10). In conclusion, the inability of hippocampal glutamine synthetase to metabolize excess amounts of glutamate may contribute to neuronal apoptosis in the hippocampal formation during meningitis.

Noninvasive neurally adjusted ventilatory assist (NAVA) has been shown to improve patient-ventilator interaction in many settings. There is still scarce data with regard to postoperative patients indicated for noninvasive ventilation (NIV) which this study elates. The purpose of this trial was to evaluate postoperative patients for synchrony and comfort in noninvasive pressure support ventilation (NIV-PSV) vs. NIV-NAVA. Methods. Twenty-two subjects received either NIV-NAVA or NIV-PSV in an object-blind, prospective, randomized, crossover fashion (observational trial). We evaluated blood gases and ventilator tracings throughout as well as comfort of ventilation at the end of each ventilation phase. Results. There was an effective reduction in ventilator delays (p<0.001) and negative pressure duration in NIV-NAVA as compared to NIV-PSV (p<0.001). Although we used optimized settings in NIV-PSV, explaining the overall low incidence of asynchrony, NIV-NAVA led to reductions in the NeuroSync-index (p<0.001) and all types of asynchrony except for double triggering that was significantly more frequent in NIV-NAVA vs. NIV-PSV (p=0.02); ineffective efforts were reduced to zero by use of NIV-NAVA. In our population of previously lung-healthy subjects, we did not find differences in blood gases and patient comfort between the two modes. Conclusion. In the postoperative setting, NIV-NAVA is well suitable for use and effective in reducing asynchronies as well as a surrogate for work of breathing. Although increased synchrony was not transferred into an increased comfort, there was an advantage with regard to patient-ventilator interaction.

The electrical activity of the diaphragm (EAdi) allows one to monitor the patients' respiratory drive and their ability to meet the increased respiratory demand.

Methods: We studied 18 mechanically ventilated patients considered difficult to wean. For a spontaneous breathing trial (SBT), the patients were disconnected from the ventilator and given oxygen through a T-piece. The SBT was evaluated by using standard criteria. Results: Twelve patients completed the SBT successfully, and six failed. The EAdi was significantly different in the two groups. We found an early increase in EAdi in the failing patients that was more pronounced than in any of the patients who successfully passed the SBT. Changes in EAdi predicted an SBT failure earlier than did conventional parameters.

Pulmonary involvement in ASyS significantly increases morbidity and mortality and, therefore, requires prompt and effective immunosuppressive treatment. Owing to the rarity of ASyS, limited data exists on progression and prognosis of ILD under immunosuppression. Objectives: The objective of the study was to evaluate the radiological progression and outcome measures of ILD with immunosuppressive therapy in patients with ASyS. Methods: Twelve patients with ASyS-associated ILD (ASyS-ILD) were included. Demographic and clinical data, including organ involvement, pulmonary function tests (PFT), laboratory parameters, imaging studies, and treatment regimens were retrospectively analyzed from routinely collected data. The extent of ground glass opacities, fibrotic changes and honeycombing was analyzed and scored using high-resolution chest computed tomography (HRCT) scans. HRCT findings were compared between baseline and follow-up examinations. In addition, patients were stratified depending on whether they had received rituximab (RTX) or not. Results: Pulmonary function tests revealed stable lung function and follow-up HRCT scans showed an improvement of radiological alterations in the majority of ASyS patients under immunosuppressive therapy. We did not detect significant differences between the RTX- and non-RTX-treated groups, but the RTX-treated patients more frequently had myositis and relapsing disease. Conclusions: Radiographic alterations in ASyS-associated ILD respond to immunosuppressive treatment.
