Abstract
OBJECTIVE Obstructive Sleep Apnea (OSA) has been associated with both subclinical and accelerated atherosclerosis; however, it still remains unknown whether this association is unique or is mediated by the higher burden of co-existing cardio-metabolic disorders frequently seen in patients with OSA. PATIENTS AND METHODS A total of 40 subjects without clinically diagnosed cardiovascular disease (CVD) referred for polysomnography test were included in the study. Subjects with apnea/hypopnea index (AHI > 15/h) were classified as moderate/severe OSA. Subclinical changes in carotid atherosclerosis were assessed using mean carotid intima-media thickness (cIMT) and presence of atheromatic plaques on both carotid arteries. The measurement was performed using B-mode ultrasonogram. Framingham risk score was used in the approximation of cardiovascular risk. RESULTS The mean age of our cohort was 56.8 years, 70% (n = 28) of whom were males. Moderate/severe OSA was diagnosed in 21 subjects. Both groups were well matched in terms of clinical and demographic characteristics, and cardiovascular risk profile, as shown in their respective Framingham risk scores (10.4 ± 6.6 vs. 11.8 ± 8.8, p = NS). Patients with moderate/severe OSA had a higher mean AHI, 3% oxygen desaturation index, and lower minimum nocturnal oxygen saturation than controls. No significant differences were detected in terms of C-reactive protein levels. The two groups had similar cIMT (0.66 ± 0.17 vs. 0.75 ± 0.20 p = 0.33) and presence of atheromatic plaque (50% vs. 45%, p = 1.00). CONCLUSIONS Our study suggests that among patients with similar cardiovascular risk profile and free of overt CVD, the severity of newly diagnosed OSA was not correlated with increased inflammation or subclinical carotid atherosclerosis.

Abstract
Longstanding asthmatic bronchitis, without evidence of underlying disease, occurring in middle-aged patients, is usually attributed to chronic obstructive pulmonary disease and is treated appropriately. We report a case of 2-year asthmatic bronchitis with recurrent attacks of wheezing, in a 60-year-old patient. He had three repeated hospitalizations, in different institutions, where he was treated for exacerbations of chronic bronchitis complicated by lower respiratory tract infections. During his final hospitalization, a tracheal hamartoma was found and removed, releasing him from his symptoms.

Abstract
Brucellosis remains a diagnostic puzzle. We retrospectively studied the case notes of 105 patients with brucellosis who were admitted in the Department of Internal Medicine of the University of Patras Hospital, a tertiary care institution serving an extended rural area in western Greece, from 2003 to 2006. Five unusual causes of brucellosis were identified: hepatic, epidural and thyroid abscesses, intrahepatic cholestatic liver disease and pancytopenia. Virtually every human organ and system can be involved in brucellosis, which highlights the need to include brucellosis in the differential diagnosis, especially in endemic areas.

Abstract
Human cases due to Salmonella enterica subsp. arizonae are especially rare, but it may affect immunocompromised patients and infants. We present a case of endocarditis in a patient with sickle cell disease and a review of earlier cases caused by this rare human pathogen. The patient was successfully treated with ceftriaxone and ciprofloxacin. There are only few cases of salmonella endocarditis reported in the last six decades and it is the first case of Salmonella enterica subsp. arizonae endocarditis in the literature to the best of our knowledge.

Abstract
Adiponectin possesses anti-inflammatory, insulin-sensitizing and anti-atherosclerotic properties. The aim of this study was to assess the levels of serum adiponectin in patients with chronic viral hepatitis C and B and correlate them with parameters exploring insulin resistance and indices of chronic liver disease. Seventy-two patients with chronic hepatitis C virus (HCV) infection and 73 patients with chronic hepatitis B virus (HBV) infection, matched for age and sex, were studied. All individuals were examined for serum concentrations of adiponectin, insulin, C-peptide and homeostasis model assessment for insulin resistance (HOMA-IR). Viral parameters and liver histology were also evaluated. Serum adiponectin levels were significantly higher in HCV compared with HBV-infected patients. Correlation analysis in the whole group demonstrated that serum adiponectin was positively correlated with aspartate aminotransferase, alkaline phosphatase, globulins, high-density lipoprotein cholesterol and staging score, while it was negatively correlated with body mass index, insulin, C-peptide and HOMA-IR. Logistic regression analysis identified type of infection (HCV vs HBV), alcohol consumption more than 25 g daily, serum total globulin and low C-peptide as significant predictive variables associated with high adiponectin levels. Higher levels of serum adiponectin in HCV compared with HBV patients could have a role in the slower disease progression of chronic HCV infection. In addition, alcohol intake more than 25 g daily seems to be a significant predictor for hyperadiponectinaemia in patients with chronic viral hepatitis C or B. Finally, in this study, a clear positive association between adiponectin and hepatic necroinflammation or staging score was not found.

Abstract
Lipoproteins are closely connected to the process of hepatitis C virus (HCV) infection. The aim of this study was to evaluate the lipaemic profile in patients with chronic HCV infection, and to identify any association between serum lipid levels and viral load, HCV genotype or liver histology. Total cholesterol (TC), high-density lipoprotein-cholesterol (HDL-C), low-density lipoprotein-cholesterol (LDL-C) and triglycerides (TG) were measured in the sera of 155 patients with chronic HCV infection and 138 normal subjects, matched for age and sex. Viral parameters and liver histology were evaluated in HCV-infected patients. Serum TC (P < 0.0005), HDL-C (P < 0.0005) and LDL-C (P < 0.0005) were lower in chronic hepatitis C patients compared with controls. Grading score was positively correlated with TC and LDL-C. Patients with HCV genotype 3a had significantly lower levels of TC, HDL-C, LDL-C, higher viral load and higher frequency of hepatic steatosis than those with other genotypes. Logistic regression analysis identified genotype 3a (OR, 6.96; 95% CI, 2.17-22.32, P = 0.0011) as the only significant predictive variable associated with low serum cholesterol concentration. HCV infection is associated with clinically significant lower cholesterol levels (TC, LDL and HDL) when compared with those of normal subjects. This finding is more pronounced in patients infected with HCV genotype 3a. Further studies are necessary to define the pathophysiology of the relationship between lipid metabolism and HCV infection.

Abstract
In the present study the effect of ciprofloxacin versus ceftazidime on concentrations of pro- and anti-inflammatory cytokines in the sera of patients with severe sepsis was evaluated. The study included 58 previously healthy patients suffering from severe sepsis caused by gram-negative bacteria, treated with either ciprofloxacin or ceftazidime after thorough clinical and microbiological evaluation and followed up for clinical outcome. Levels of the proinflammatory cytokines tumor necrosis factor alpha (TNF-alpha), interleukin-1b (IL-1b), IL-6, and IL-8 and of the anti-inflammatory cytokine IL-10, as well as of IL-1 receptor antagonist and soluble TNF receptors I and II, in serum were measured at baseline and 24 and 48 h after the first antimicrobial dose. Mean SAPS-II scores, development of septic shock, and mortality rates were similar in the two groups (43.2 +/- 9.2, 21.4%, and 14.3% in the ceftazidime group versus 49.8 +/- 11.3, 20%, and 13.3% in the ciprofloxacin group). Serum TNF-alpha and IL-6 levels at 24 and 48 h were significantly lower in the ciprofloxacin group, while the IL-10/TNF-alpha ratio was significantly higher, than those for the ceftazidime group. Among patients with high baseline TNF-alpha levels, there were significant increases in the IL-10/TNF-alpha ratio at both 24 and 48 h over that at admission for the ciprofloxacin group, while no differences were noted in the ceftazidime group. These results indicate that ciprofloxacin may have an immunomodulatory effect on septic patients by attenuating the proinflammatory response, while there is no evidence that differences in the cytokines measured have any impact on the final outcome.

Abstract
In this randomized, non-blinded study, the efficacy and safety of a 5-day course of moxifloxacin (one 400 mg tablet daily) was compared with that of co-amoxiclav (one 625 mg tablet every 8h) for 7 days, for the treatment of acute exacerbations of chronic bronchitis (AECB). A total of 162 patients with clear signs of an acute exacerbation of chronic bronchitis were enrolled. Of these, 153 could be studied. Seventy-nine patients were randomized in the moxifloxacin arm and 74 in the co-amoxiclav arm of the study. The primary efficacy parameter was clinical response at 14 days in the evaluable population. A clinical success was classified as resolution or improvement of symptoms. Variables used to assess clinical response included wheeze, cough, dyspnoea, sputum volume, rales and ronchi. The success rate in the moxifloxacin group was 88.6% (70 of 79) and that for co-amoxiclav group was 89.2% (66 of 74). At follow-up (28-35 days post-treatment), the continued clinical cure rates were 90.0% (63 of 70) for moxifloxacin and 89.4% (59 of 66) for co-amoxiclav. No significant differences were detected between the two groups. A total of 78 pathogenic bacteria were isolated from the sputum samples of the patients, with Moraxella catarrhalis, Haemophilus influenzae and Streptococcus pneumoniae being the most frequently isolated pathogens. The eradication rate at 14 days in the valid patients was similar for both groups, 90.9% (20 of 22) for the moxifloxacin group and 90.0% (18 of 20) for the co-amoxiclav group. Both drugs were well tolerated with no differences in the drug-related adverse effects or the patients withdrawing because of an adverse event. These results and the good spectrum of antibacterial activity make moxifloxacin a promising and also safe alternative for the empirical treatment of AECB.

Abstract
The efficacy and the safety of sequential intravenous/oral (i.v./p.o.) ciprofloxacin (CIPX) plus i.v./p.o. metronidazole (MTR) was compared with i.v. ceftriaxone (CTRX) plus i.v./p.o. MTR in the treatment of complicated intra-abdominal infections. One hundred and forty two patients received study medications. Of these, 135 could be studied. Sixty-nine patients were randomized in the CIPX arm of the study and 66 in the CTRX arm. In the CIPX group 58 patients were switched to oral treatment and 11 patients remained in the intravenous arm. In the CTRX group 57 patients switched to oral MTR continuing i.v. CTRX and 9 patients remained in the i.v. branch. Success rates at the end of treatment in patients who switched to oral were 100% in both the CIPX group and the CTRX group. For validated patients continuing on oral, the success rates at the end of treatment were 63.6 and 33.3% in the CIPX and CTRX groups respectively. Overall success rates at the end of treatment and follow-up in all patients were 94.2% in the CIPX group and 89.4% in the CTRX group. Overall success rates at the end of treatment in patients with proven bacterial infection were 92.9% in the CIPX group and 88.3% in the CTRX group. Duration of hospitalization (days) for studied patients was 22.7+/-8.2 in the CIPX and 19.6+/-14.5 in the CTRX group. There was no statistical difference between the CIPX and CTRX groups in both the intent to treat and in the modified intent to treat populations. Conversion to oral therapy with CIPX/MTR was as effective as continued intravenous therapy with CTRX and oral MTR in those patients able to tolerate oral feeding.

Abstract
Two point prevalence surveys of nosocomial infections (NIs) were carried out in a Greek University hospital on an annual basis in 1998 and 1999. The overall prevalence of NIs was 9.5% and 9.1% in the first and second study, respectively. The average length of stay of patients in the hospital (ALOS) was 7.7 and 9.6 days in these two studies, respectively. Of the 97 NIs detected, the most frequent were lower respiratory tract infections (36%). Urinary tract infections, bloodstream infections, surgical site infections, and gastrointestinal infections were found in 25.8%, 19.6%, 7.2% and 4.1% of patients, respectively. The prevalence of antibiotic usage was 55.6% in 1998 and 54.1% in 1999. Empiric antibiotic therapy prevailed over prophylactic and rational therapies. These percentages are higher than those reported from other countries, emphasizing the need for rational antibiotic usage to decrease pharmacy expenses and discourage the development of resistant microorganisms. A nationwide network of surveillance of NIs in Greece is now being developed using these experiences.
