Unusual cardiovascular complications of brucellosis presenting in two men: two case reports and a review of the literature
Introduction: Brucellosis is a zoonosis with worldwide distribution, which is particularly endemic in many countries of the Mediterranean basin. Cardiovascular complications of this disease, such as endocarditis, myocarditis and pericarditis, are very rare, with even fewer cases of myocarditis or asymptomatic pericardial effusion in the absence of concomitant endocarditis being reported. Case presentation: We report two cases of brucellosis in two Caucasian men, aged 17 and 34 years old, with myocarditis and asymptomatic pericardial effusion, respectively. Of note, neither patient had concomitant endocarditis. The disease was confirmed serologically and by blood cultures. Both patients recovered completely after receiving appropriate antibiotic treatment without any sign of relapse during a follow-up of 12 months. Conclusion: These two cases emphasize that in endemic areas Brucella can be considered as a potentially causative agent of idiopathic pericardial effusion or myocarditis, even in the absence of concomitant endocarditis. This possibility could be taken into account particularly in cases where contraction of brucellosis is possible, such as occupational exposure or consumption of unpasteurized dairy products. © 2011 Gatselis et al; licensee BioMed Central Ltd
Impact of antimicrobial drug restrictions on doctors' behaviors
Background/aim: Broad-spectrum antibiotics have become available for use only with the approval of infectious disease specialists (IDSs) since 2003 in Turkey. This study aimed to analyze the tendencies of doctors who are not disease specialists (non-IDSs) towards the restriction of antibiotics.Materials and methods: A questionnaire form was prepared, which included a total of 22 questions about the impact of antibiotic restriction (AR) policy, the role of IDSs in the restriction, and the perception of this change in antibiotic consumption. The questionnaire was completed by each participating physician.Results: A total of 1906 specialists from 20 cities in Turkey participated in the study. Of those who participated, 1271 (67.5%) had 5 years of occupational experience in their branch expressed that they followed the antibiotic guidelines more strictly than the JSs (P < 0.05) and 755 of physicians (88%) and 720 of surgeons (84.6%) thought that the AR policy was necessary and useful (P < 0.05).Conclusion: This study indicated that the AR policy was supported by most of the specialists. Physicians supported this restriction policy more so than surgeons did
Positive airway pressure (PAP) treatment reduces glycated hemoglobin (HbA1c) levels in obstructive sleep apnea patients with concomitant weight loss: Longitudinal data from the ESADA
Patients with obstructive sleep apnea (OSA) are at increased risk of developing metabolic disease such as diabetes. The effects of positive airway pressure on glycemic control are contradictory. We therefore evaluated the change in glycated hemoglobin (HbA1c) in a large cohort of OSA patients after long-term treatment with positive airway pressure. HbA1c levels were assessed in a subsample of the European Sleep Apnea Database [n=1608] at baseline and at long-term follow up with positive airway pressure therapy (mean 378.9±423.0 days). In a regression analysis, treatment response was controlled for important confounders. Overall, HbA1c decreased from 5.98±1.01% to 5.93±0.98% (p=0.001). Patient subgroups with a more pronounced HbA1c response included patients with diabetes (−0.15±1.02, p=0.019), those with severe OSA baseline (−0.10±0.68, p=0.005), those with morbid obesity (−0.20±0.81, p<0.001). The strongest HbA1c reduction was observed in patients with a concomitant weight reduction >5 kilos (−0.38±0.99, p<0.001). In robust regression analysis, severe OSA (p=0.038) and morbid obesity (p=0.005) at baseline, and weight reduction >5 kilos (p<0.001) during follow up were independently associated with a reduction of HbA1c following PAP treatment. In contrast, PAP treatment alone without weight reduction was not associated with significant Hb1Ac reduction. In conclusion, positive airway pressure therapy is associated with HbA1c reduction in patients with severe OSA, in morbidly obese patients. and most obviously in those with significant weight lost during the follow-up. Our study underlines the importance to combine positive airway pressure use with adjustments in lifestyle to substantially modify metabolic complications in OSA
Arterial bicarbonate is associated with hypoxic burden and uncontrolled hypertension in obstructive sleep apnea - The ESADA cohort
Objective: Blood bicarbonate concentration plays an important role for obstructive sleep apnea (OSA) patients to maintain acid-base balance. We investigated the association between arterial standard bicarbonate ([HCO3-]) and nocturnal hypoxia as well as comorbid hypertension in OSA. Methods: A cross-sectional analysis of 3329 patients in the European Sleep Apnea Database (ESADA) was performed. Arterial blood gas analysis and lung function test were performed in conjunction with polysomnographic sleep studies. The 4% oxygen desaturation index (ODI), mean and minimum oxygen saturation (SpO2), and percentage of time with SpO2 below 90% (T90%) were used to reflect nocturnal hypoxic burden. Arterial hypertension was defined as a physician diagnosis of hypertension with ongoing antihypertensive medication. Hypertensive patients with SBP/DBP below or above 140/90 mmHg were classified as controlled-, uncontrolled hypertension, respectively. Results: The [HCO3-] level was normal in most patients (average 24.0 ± 2.5 mmol/L). ODI, T90% increased whereas mean and minimum SpO2 decreased across [HCO3-] tertiles (ANOVA, p = 0.030, <0.001, <0.001, and <0.001, respectively). [HCO3-] was independently associated with ODI, mean SpO2, minimum SpO2, and T90% after adjusting for confounders (β value [95%CI]: 1.21 [0.88–1.54], −0.16 [-0.20 to −0.11], −0.51 [-0.64 to −0.37], 1.76 [1.48–2.04], respectively, all p < 0.001). 1 mmol/L elevation of [HCO3-] was associated with a 4% increased odds of uncontrolled hypertension (OR: 1.04 [1.01–1.08], p = 0.013). Conclusion: We first demonstrated an independent association between [HCO3-] and nocturnal hypoxic burden as well as uncontrolled hypertension in OSA patients. Bicarbonate levels as an adjunctive measure provide insight into the pathophysiology of hypertension in OSA

FLORA INFEKSIYON HASTALIKLARI VE KLINIK MIKROBIYOLOJI DERGISI
Introduction: Fungal infections are vital problems worldwide and their incidence have increased along with changing patient profile. Particularly candida species is still the most commonfungal agent, and the significance of non-albicans candida species have gained importance in recent years. In the present study, it was aimed to evaluate retrospectively the risk factors and distribution of candida species in patients with invasive candida infections, who were treated with anidulafungin. Materials and Methods: In the first three years (1 January 2012 to 31 December 2014) when anidulafungin came out in our country, we retrospectively evaluated the data of the patients with invasive candida infections who were treated by anidulafungin for more than 48 hours in seven university hospitals. Data were recorded to the case report forms. Results: Two hundreds and fifty-seven patients were included into the study. Fifty-six percent of the patients were male and mean age was 58.57 +/- 19.5 years. Two hundreds and three patients (79%) were hospitalized in intensive care units, 37 (14.3%) in internal medicine services, and 17 (0.07%) in surgery services. As previously described, we detected antibiotic usage in the last month (%96.9), presence of urinary catheter (90.3%) and presence of central venous catheter (82.1%) as risk factors for invasive candida infections. More than half of the patients (57.1%) with central venous catheter had candidemia. Sixty-six (47.7%) of the blood isolates were Candida albicans, 33 (23.7%) were Candida parapsilosis, 17 (12.2%) were Candida tropicalis and 13 (9.4%) were Candida glabrata. During follow up, 64.5% of 124 patients whose catheters couldn't be taken off and 47.6% of 86 patients whose catheters could be taken off died. During anidulafungin treatment, one anaphylaxis, one skin eruption and one thrombocytopenia were seen as side effects. Conclusion: In our study, we found that removal of central venous catheter of the patients with candidemia was a positive effect on mortality. We suggest that patients with candidemia, insisting on catheter removal besides antifungal treatment is necessary. We observed that anidulafungin is an effective and safe choice in invasive candida infections
Is Tigecycline a Good Choice in the Treatment of Multidrug-Resistant Acinetobacter baumannii Pneumonia?
WOS: 000300750800005PubMed ID: 22233818The aim of this study was to evaluate the efficacy of tigecycline in multidrug-resistant (MDR) Acinetobacter baumannii pneumonia. We retrospectively evaluated the outcome of adult patients with culture proven MDR A. baumannii pneumonia treated with tigecycline between January 2009 and March 2011. The study comprised a total of 72 MDR A. baumannii pneumonia cases (44 men, mean age 65.9 +/- 15.0). Tigecycline was used for a mean duration of 10.7 +/- 4.8 days. Microbiological eradication was observed in 47 cases (65.3%). Overall mortality was 55.5% and was lower in cases with microbiological eradication vs others (15/47 32% vs 25/25 100%, p0.05). Patients who died had lower albumin levels, higher APACHE-II scores and CRP levels. The microbiological eradication rate of tigecycline in MDR A. baumannii was considerable. However, eradication of A. baumannii did not result in favorable clinical outcomes in those patients with low albumin, higher APACHE-II scores and CRP levels
Dyslipidemia prevalence in nonobese, nondiabetic patients with obstructive sleep apnea: does sex matter?
STUDY OBJECTIVES: Dyslipidemia in obstructive sleep apnea (OSA) has been attributed to confounding obesity and/or diabetes. This study aimed to examine lipid profiles in nondiabetic, nonobese patients with OSA and identify the possible effects of age and sex. METHODS: We retrospectively evaluated the lipid parameters of 3,050 adults who underwent polysomnography. A total of 2,168 patients were excluded due to obesity (body mass index ≥ 30 kg/m2), diabetes, alcoholism, untreated hypothyroidism, lipid-lowering drug use, missing sleep data, or treatment for suspected OSA. RESULTS: Of 882 patients (75% males, aged 46.8 ± 12.2 years) included in the study, 88.4% had OSA. Levels of total cholesterol (P = .003), low-density-lipoprotein (LDL) cholesterol (P = .005), non-high-density-lipoprotein (non-HDL) cholesterol (P = .001), and triglycerides (P = .007) were significantly higher in patients with OSA than in those without, whereas HDL-cholesterol levels did not differ. The proportion of patients with hypercholesterolemia and/or elevated non-HDL cholesterol (>  160 mg/dL) was significantly higher in OSA than in non-OSA. Correlation analyses by sex revealed stronger and more significant relationships between lipid parameters and apnea-hypopnea index in women than in men (r = .135, P .001, vs r = .080, P = .043 for total cholesterol; r = .111, P .001, vs r = .080, P = .046 for non-HDL cholesterol; r = .122, P .001, vs r = .061, P = .107 for LDL cholesterol, respectively). In regression analysis, the rate of hypercholesterolemia increased with age (P .001 for women and P = .031 for men); non-HDL- and LDL-cholesterol levels significantly increased with OSA severity (P = .035 and P = .023, respectively) and age (P = .004 and P = .001, respectively) in women. CONCLUSIONS: After excluding confounding obesity and diabetes, patients with OSA have an impaired lipid profile including total cholesterol, LDL cholesterol, non-HDL cholesterol, and triglycerides. A significant association between dyslipidemia and OSA severity was observed in women but not in men. CITATION: Basoglu OK, Tasbakan MS, Kayikcioglu M.
