There remains to this day a great gap in understanding as to the role of B cells and their products-antibodies and cytokines-in mediating the protective response to Francisella tularensis, a Gram-negative coccobacillus belonging to the group of facultative intracellular bacterial pathogens. We previously have demonstrated that Francisella interacts directly with peritoneal B-1a cells. Here, we demonstrate that, as early as 12 h postinfection, germ-free mice infected with Francisella tularensis produce infection-induced antibody clones reacting with Francisella tularensis proteins having orthologs or analogs in eukaryotic cells. Production of some individual clones was limited in time and was influenced by virulence of the Francisella strain used. The phylogenetically stabilized defense mechanism can utilize these early infection-induced antibodies both to recognize components of the invading pathogens and to eliminate molecular residues of infection-damaged self cells.

OBJECTIVE: To identify early clinical and MRI predictors of non-response to interferon (IFN) treatment in multiple sclerosis (MS). METHODS: In 172 patients with relapsing-remitting MS treated with IFNβ, we evaluated prediction of future treatment non-response. Candidate predictors comprised disability and its sustained progression, relapse score (combining frequency and severity of relapses), brain volume change, brain parenchymal fraction, number of new T2 lesions, and T2 and T1 lesion volume within the initial year of treatment. Treatment non-response was evaluated as confirmed disability progression or overall average annual relapse score exceeding 1 over the following 5 years. Logistic regression model was adjusted for patient age, gender, disease duration and changes in treatment. RESULTS: Ninety patients (52%) reached the status of IFN non-responders in years 2-6. Patients with ≥1 new T2 lesion and relapse score ≥2 (odds ratio ≥5.7) or those with ≥3 new T2 lesions regardless of the relapse score (odds ratio = 3) were in a significantly higher risk of future treatment non-response. CONCLUSIONS: In patients with MS treated with IFNβ for 1 year, number of new T2 lesions and annualized relapse score predict individual risk of treatment non-response over the following 5 years.

Autori analyzovali vzťah medzi výskytom predpokladaných príznakov generalizácie zápalovej odpovede počas skorej postagresívnejfázy a klinickým vývojom v skupine pacientov identifikovaných ako vysoko rizikových pre vývoj sekundárneho MODS. Ako príznaky generalizácie zápalovej odpovede použili pozitívnu vodnú bilanciu, pokles sérovej koncentrácie albumínu, pokles počtu trombocytov, pokles aktivity ATIII, a pozitivitu testu na D-dimér/FDP usporiadaných do jednoduchého algoritmu. Výsledky analýzy ukázali, že pri použití uvedených príznakov je možné identifikovať generalizáciu zápalovej odpovede a súčasne „skutočne rizikový vývoj" už počas latentnej fázy sekundárneho MODS.
Authors have analysed relationship between supposed signs of generalisation of inflammatory response in the course of early postaggressiv period and the outcome in group identificated as high risk for secondary MODS development. As signs of generalisation of inflammatory response were taken signs of systetnic endothelium injury (positive fluid balance, S-albumin decrease, thrombocytopenia, low level of ATIII activity and D-dimer/FDP positivity). In their results authors can identify with signs mentioned above generalisation of inflammatory response and at the same time „ really risk development" even in the course of latent period of secondary MODS.

Even brief acoustic trauma during the critical period of development that results in no permanent hearing threshold shift may lead to altered auditory processing in adulthood. By monitoring the acoustic startle response (ASR), we examined the development of auditory function in control rats and in rats exposed to intense noise at the 14th postnatal day (P14). First ASRs appeared on P10-P11 to intense low-frequency tones. By P14, the range of sound intensities and frequencies eliciting ASRs extended considerably, the ASR reactivity being similar at all frequencies (4-32 kHz). During the subsequent two weeks, ASR amplitudes to low-frequency stimuli (4-8 kHz) increased, whereas the ASRs to high-frequency tones were maintained (16 kHz) or even decreased (32 kHz). Compared to controls, noise exposure on P14 (125 dB SPL for 8, 12, or 25 min) produced transient hyper-reactivity to startle stimuli, manifested by a decrease of ASR thresholds and an increase of ASR amplitudes. ASR enhancement occurred regardless of permanent hearing loss and was more pronounced at high frequencies. The hyper-reactivity of ASRs declined by P30; the ASR amplitudes in adult exposed rats were lower than in controls. The histological control did not reveal loss of hair cells in adult exposed rats, however, the number of inner hair cell ribbon synapses was significantly decreased, especially in the high-frequency part of the cochlea. The results indicate that early acoustic trauma may result in complex changes of ASRs during development.
