Wine: positive and negative effects to neurologic, infectious and cardiovascular diseases.

Data on both positive (protective) and negative effect of wine on cardiovascular, neurologic and immune system are briefly reviewed.

The influence of wine Zweigeltrebe and Breslava Chateau Karvaj on blood pressure in healthy volunteers.

Efficacy of varies wine sorts on blood pressure in 21 healthy individuals was prospectively studied. White wine Breslava most significantly decreased systolic blood pressure in comparison to wines from supermarket Veltlin or Frankovka (Blaufränkisch, Caberner Franc) (Raca). Decrease in diastolic blood pressure is similar in both white wines Breslava respectively Veltlin. In the second experiment during 8 hours blood pressure measurement, white wine Breslava from Nove Zamky region more significantly decreased systolic blood pressure in comparison to Low Carpathian wines (region Raca). Both white wines significantly decreased diastolic blood pressure. Red wines from both regions did not have significant influence on systolic or diastolic blood pressure in doses of 1, 2 or 3 dcl.

Overall alcohol intake, beer, wine and systemic markers of inflamation in western europe: results from three MONICA samples (Augsburg, Glasgow, Lille).

Anti-inflammatory effects of moderate alcohol consumption have been proposed to explain why moderate alcohol intake lowers coronary heart disease risk. The relationship between overall alcohol, beer or wine consumption and markers of systemic inflammation in three different geographical areas in Europe, was investigated.

Occurrence of coronary heart diseases and hypertension among wine and concentrating alcohol consumers.

There was a significant difference in occurrence of coronary hearth disease and arterial hypertension occurrence in the sample of 16,345 patients living in northeast part of Slovak republic near Polish frontier versus to the viticulture regions of Nove Zamky, Sturovo in favour of villages in Bardejov region. Another difference was that 80 years and older respondents live significantly more frequently in south Slovakian viticulture villages.

Positive effect of flavonoids to cardiovascular and central nervous system.

Moderate intake of wine may be protective against various neurologic, cardiovascular and gastroenteric diseases. Low concentration of alcohol (wine diluted with water 1:2 to 1:10) exhibits strong antimicrobial activity against majority of gastrointestinal pathogens as well as against Chlamydia pneumoniae. In contrast, higher doses of even diluted alcohol (more than 5-7 glasses a day) may cause severe neuropsychic disorders with major social consequences. Wine contains variety of molecules with cardioprotective effect and antiinfectious properties.

Comparison of postsurgical and community acquired bacterial meningitis--analysis of 372 cases within a nationwide survey.

The aim of this study was to assess if differences in etiology and risk factors among 372 cases of bacterial meningitis acquired after surgery (PM) or in community (CBM) have impact on outcome of infected patients. Among 372 cases of bacterial meningitis within last 17 years from 10 major Slovak hospitals, 171 were PM and 201 CBM. Etiology, risk factors such as underlying disease, cancer, diabetes alcoholism, surgery, VLBW, ENT infections, trauma, sepsis were recorded and mortality, survival with sequellae, therapy failure were compared in both groups. Significant differences in etiology and risk factors between both groups were reported. Those after neurosurgery had more frequently Coagulase negative staphylococci (p<0.001), Enterobacteriaceae (p=0.01) and Acinetobacter baumannii (p=0.0008) isolated from CSF and vice versa Streptococcus pneumoniae (p<0.001), Neisseria meningitis (p<0.001) and Haemophillus influenza (p=0.0009) were more commonly isolated from CSF in CBM. Neurosurgery (p<0.001), sepsis (p=0.006), VLBW neonates (p=0.00002) and cancer (p=0.0007) were more common in PM and alcohol abuse (p<0.001) as well as otitis/sinusitis (p<0.001) and Roma ethnic group (p=0.001) in CAM. Initial treatment success was significantly more frequently observed among CAM (p<0.001) but cure after modification was more common in PM (p=0.002). Therefore outcome in both groups was similar (14.6% vs. 12.4%, p=NS).

Bacterial meningitis after craniocerebral trauma in the community.

Craniocerebral trauma is one of major risk factors for development of meningitis. We reviewed 30 cases of bacterial meningitis occurring in community after craniocerebral trauma. Alcohol abuse was significant risk factor occurring in trauma patients with meningitis present in 50% in our cohort (p=0.0001). The most common pathogen in posttraumatic meningitis was Str. pneumoniae (90% vs. 33.8%, p=0.0001). However mortality was very low, only 5% probably because of early diagnosis and treatment of patients at risk for bacterial meningitis but neurologic sequellea were significantly more common (p=0.00001) in patients after craniocerebral trauma.

Bacterial meningitis after sinusitis and otitis media: ear, nose, throat infections are still the commonest risk factors for the community acquired meningitis.

We investigated how many cases of bacterial meningitis in our national survey were associated with sinusitis or otitis media. Among 372 cases of bacterial meningitis within our nationwide 17 years survey, 201 cases were community acquired (CBM) and in 40 (20%) otitis media or sinusitis acuta/chronica were reported 1-5 weeks before onset of CBM. Diabetes mellitus (20% vs. 7.5%, p=0.01), alcohol abuse (35% vs. 15.4%, p=0.003) and trauma (30% vs. 14.9%, p=0.02) were significantly associated with CBM after ENT infections. Concerning etiology, CBM after sinusitis/otitis was insignificantly associated with pneumococcal etiology (50% vs. 33.8 %, NS) and significantly associated with other (L. monocytogenes, Str. agalactiae) bacterial agents (9.9 % vs. 25 %, p=0.008) . However those significant differences for new ENT related CBM had no impact on mortality (12.4 % vs. 5%, NS), failure after initial antibiotics (10 % vs. 9.5%, NS) and neurologic sequellae (12.5 % vs. 15.4 %, NS).

Pneumococcal meningitis in community is frequent after craniocerebral trauma and in alcohol abusers.

Aim of this short communication was to assess risk factors and outcome of community acquired pneumococcal meningitis and compare it to all cases of community acquired meningitis. Univariate analysis was used for comparison of 68 pneumococcal to 201 CBM within a Slovak nationwide database of CBM. Significant risk factors for pneumococcal meningitis were previous craniocerebral trauma within 7 days (39.7% vs. 14.9%, p=0.00002), splenectomy (10.3% vs. 3.5%, p=0.03) and alcohol abuse (36.8% vs. 15.4%, p=0.0001). Concerning outcome, mortality was similar (8,8% and 12,4%, NS), proportion of those with neurologic sequellae after CBM due to Str. pneumoniae was insignificantly higher (20.6% vs. 15.4%, NS) in comparison to all CBM. All but 2 strains Str. pneumoniae were susceptible to penicillin and macrolides (3.3% resistance).

Gram-negative bacillary community acquired meningitis is not a rare entity in last two decades.

The aim of this short note is to assess gram-negative bacillary community acquired meningitis (CBM) and nosocomial meningitis (NM) within 17 years nationwide survey. All cases of gram-negative bacillary CBM within 1990-2007 were assessed in national database of 372 patients with bacterial meningitis: 69 of gram-negative cases were nosocomial and 24 of gram-negative meningitis cases were CBM. Those 24 cases were compared with all CBM (201 cases) for risk factors and outcome. Among nosocomial gram-negative pathogens, A. baumannii in 23 cases, Ps. aeruginosa in 15 cases and Enterobacteriaceae in 31 cases were isolated. Among CBM, in 13 cases Enterobacteriaceae (Escherichia coli 6, Klebsiella pneumoniae 3, Proteus mirabilis 2, Enterobacter cloacae 2), in 5 cases Ps. aeruginosa and in 6 cases Acinetobacter baumannii were isolated from cerebrospinal fluid (CSF). The only significant risk factor for CBM due to gram-negative bacilli was neonatal age (12.5% vs. 3.5%, p=0.04) as underlying disease. However, mortality among gram-negative bacillary meningitis was significantly higher (12.4% vs. 37.5%, p=0.001) in comparison to other meningitis.

Bacterial meningitis among Roma ethnic minority.

Etiology and risk factors such as malnutrition, diabetes, otitis/sinusitis, alcohol abuse, tuberculosis, low birth weigh as well as mortality and neurologic sequellea in Roma ethnic minority with community acquired bacterial meningitis (CBM) was assessed and compared to all CBM cases.

Bacteremic meningitis is associated with inferior outcome in comparison to community acquired meningitis without bacteremia.

Meningitis associated with bacteremia is rare. Bacteremic form of meningitis occurred in 28 of 201 cases of community acquired meningitis (14%) in Slovakia within last 17 years. Bacteremic meningitis was associated with diabetes (21.4% vs. 7.5%, p=0.02) and with higher treatment failures (32.1% vs. 9.5%, p=0.01) and higher mortality (25% vs. 12.4%, NS). In univariate analysis comparing 28 cases of bacteremic community acquired bacterial meningitis (BCBM) to all CBM, no significant risk factor concerning underlying disease (cancer, ENT infection, alcohol abuses, trauma, splenectomy, etc.) or etiology was observed apart of diabetes mellitus, which was more common among bacteremic meningitis (21.4% vs. 7.5%, p=0.02). Mortality (25% vs. 12.4%, NS) insignificantly but therapy failure (32.1% vs. 9.5%, p=0.01) was significantly more frequently observed among meningitis with bacteremia. N. meningitis was the commonest causative agent (8 of 28 cases) followed by Str. pneumoniae (6), gram-negative bacteria (6), S. aureus (4) and H. influenzae (2).

Haemophillus influenzae community acquired meningitis occurrence in children despite 10 years vaccination.

Despite of 10 years vaccination of all children within 1st year in Slovakia against H. influenzae, this severe infection still occurs. Among 201 cases of community acquired bacterial meningitis, 14 (7%) were caused by H. influenzae serotype B. Outcome however, after early institution of treatment was fortunately positive - only 1 patient died (7.1% mortality) and in 2 other neurologic sequellae occurred (14.3%), which were transient and mild.

Neuroinfections complicating foreign body implants after perinatal trauma or meningitis in 60 children.

Meningitis after artificial implants in 60 children, mainly after foreign body infections (FBI) was caused more frequently by coagulase negative staphylococci and Ps. aeruginosa than other organisms and was significantly associated with perinatal trauma, hydrocephalus, haemorrhage or VLBW and had more neurologic sequels despite mortality was similar to other nosocomial meningitis.

Infectious embolisation to the central nervous system from endocarditis: analyses of 99 cases.

Within a cohort of 606 cases of infective endocarditis, 263 were complicated and 99 embolizing, of them 32 to the central nervous system (CNS). Significant predictors of CNS embolisation were inappropriate therapy (p<0.01) and enterococcal etiology (p<0.01). Mortality in patients with CNS emboli was 65% what was significantly higher than in cases without embolisation - 15% (p<0.01).

Trends in risk factors and etiology of 606 cases of infective endocarditis over 23 years (1984-2006) in slovakia.

The aim of this study was to assess trends in risk factors, etiology, outcome and treatment strategies for endocarditis over 23 years in Slovakia. A prospective survey of 606 cases of infective endocarditis (IE) was conducted from 1984-2006. Rheumatic fever as well as previous dental surgery showed decreasing trends within the last 23 years. Also embolic complications of IE declined along with increasing rates of surgically treated patients. No significant changes in etiology were detected apart from the fact that culture-negative endocarditis increased from 10.7% to 55.4% between 1998-2001. Surgically treated patients increased from 22.7% (1984-1990) to 50.1% (2002-2006) and mortality dramatically decreased from 26.7% (1984-1990) to 5.3% (2002-2006). Staphylococcus aureus and coagulase-negative staphylococci were the leading causes (22.4% - 48%) followed by viridans streptococci (12.2%-18.2%) were a relatively stable trend over 23 years of IE in Slovakia.

Bacteremia due to Pseudomonas aeruginosa: results from a 3-year national study in the Slovak Republic.

Risk factors, mortality and antimicrobial susceptibility of Pseudomonas aeruginosa bacteremias isolated from 148 patients from all University Hospitals in Slovakia were analyzed. Only 1.2% of 169 strains of P. aeruginosa were resistant to meropenem, 4.1% to piperacillin/tazobactam, 7.7% to ceftazidime as well as cefepime and 12% to amikacin. More than 30% of P. aeruginosa were resistant to ciprofloxacin. Our analysis of risk factors for antimicrobial resistance to the particular antimicrobials, indicated no difference in risk factors and outcome in cases infected with P. aeruginosa bacteremias resistant to amikacin, piperacillin/tazobactam or ceftazidime in comparison to episodes caused by P. aeruginosa due to susceptible isolates. When comparing risk factors for P. aeruginosa bacteremia in children vs. adults, cancer vs. non-cancer patients, several differences in risk factors were observed. Neither antimicrobial resistance to amikacin, ceftazidime or piperacillin/tazobactam, nor appropriateness of therapy according to two separate analyses were associated with better outcome.

Prospective national survey of viridans streptococcal bacteraemia risk factors, antibacterial susceptibility and outcome of 120 episodes.

The aim of this study was to prospectively investigate 120 cases of viridans streptococcal bacteraemia (VSB) in 117 patients in major university hospitals in Slovakia in 2000-2002 (3 y) for antibacterial susceptibility, risk factors and outcome. From 127 episodes, 16 (13%) of VSB were caused by PEN-R strains and 13 (10%) by ERY-R strains. 32 cases had cancer as underlying disease (20 haematological), 41 had endocarditis and 35 were elderly (>65 y of age) patients. Concerning mortality, 29 of 127 patients died (24%). There were several risk factors associated with mortality. Solid tumour as underlying disease (p<0.02), stroke (p<0.002), concomitant lung infection (p<0.01), endoscopic procedure (p<0.036), intubation (p<0.0008), ventilatory support (p<0.002), and coma (p<0.009) were associated with more deaths. A comparison of 115 bacteraemias to 13 bacteraemias caused by erythromycin-resistant strains of Streptococcus viridans was performed. There were no significant differences in underlying disease, risk factors and mortality. Erythromycin resistance in bacteraemias caused by S. viridans did not have significant impact on outcome of the patients, nor did it show specific relation to analysed risk factors in our study. 14.5% of VSB were cause by PEN-resistant viridans streptococci. Risk factors for penicillin resistance were ventilatory support (p<0.01), intubation (p<0.001) and resistance to other antibiotics: 8 of 16 (50%) of PEN-R VSB were resistant also to erythromycin or cotrimoxazole or tetracycline compared with 9% of PEN-R VSB (p<0.005). Endoscopic procedures in the upper respiratory system were at risk for development of PEN-R VSB. There was also difference in outcome; 71% vs 22.5% (p<0.0002) of cases infected with PEN-R VSB died compared to PEN-S VSB. PEN-R is therefore clinically significant in VSB.
