CCHFV seroprevalence was associated with history of tick bite or tick removal from animals, employment in animal husbandry or farming, and being >40 years of age
Stenotrophomonas maltophilia Infections in Adults: Primary Bacteremia and Pneumonia
No full textBackground: Stenotrophomonas maltophilia is the third most frequent non-fermentative Gram-negative bacilli in nosocomial infections, and usually causes severe infections such as primary bacteremia and pneumonia. Objectives: The current study aimed to compare the demographic and clinical characteristics, microbiological findings and final outcomes of the patients with primary bacteremia and nosocomial pneumonia caused by S. maltophilia. Patients and Methods: The current study retrospectively evaluated patients aged 18 years and above with primary bacteremia and nosocomial pneumonia caused by S. maltophilia from January 2006 to December 2013. Medical records of patients, including reports of clinical microbiology and hospital infection control committee, were evaluated. Results: A total of 71 patients with S. maltophilia nosocomial infections, 35 (49.3%) primary bacteremia and 36 (50.7%) pneumonia, were diagnosed. There were no significant differences in gender, age, and co-morbid diseases, except chronic obstructive pulmonary disease; this infection was significantly higher in patients with pneumonia. A slightly higher 14-day mortality was found in patients with pneumonia, but the difference was not statistically significant. Inappropriate antibiotic use and presence of multiple organ dysfunction syndrome were found as independent risk factors for 14-day mortality in multivariate analysis. Conclusions: A slightly higher mortality in patients with pneumonia, caused by S. maltophilia, was strived to explain by advanced age, higher acute physiology and chronic health evaluation (APACHE II) and sepsis related organ failure assessment (SOFA) score, and also higher inappropriate antibiotic use
Brucellar pericarditis: a report of four cases and review of the literature
No full textSummaryBackgroundBrucellosis, a disease endemic in many countries including Turkey, is a systemic infectious disease. Cardiovascular complications are not frequent, and endocarditis is the main cardiac manifestation of brucellosis. Pericarditis in the absence of concomitant endocarditis is extremely rare.MethodsIn this report, we present four patients with pericarditis caused by brucellosis in the absence of concomitant endocarditis, along with a review of the published literature on brucellar pericarditis. We also searched for clinically silent pericardial effusion among patients with brucellosis. We performed routine transthoracic echocardiography (TTE) on 72 consecutive patients with newly diagnosed brucellosis in the absence of any signs and symptoms of pericarditis over a period of 6 months.ResultsThree of our patients with brucellar pericarditis recovered fully after antibiotics. The other patient received 6 days of antibiotic treatment, and her signs and symptoms regressed, but after this the patient was lost to follow-up. We did not detect pericarditis among the 72 newly diagnosed patients.ConclusionsBrucellar pericarditis is a rare clinical entity, and the morbidity and mortality in patients with brucellar pericarditis is low. Pericardiocentesis should only be performed in patients with cardiac tamponade. Moreover, the choice of antibiotics and the duration of treatment do not differ between brucellosis cases with or without isolated pericarditis. Although the prevalence of pericarditis in brucellosis is low, brucellar pericarditis should always be kept in mind in patients with acute or chronic pericarditis, especially in areas where brucellosis is endemic
Association of MCP‐1 promotor polymorphism with disease severity of Crimean‐Congo hemorrhagic fever
No full textCrimean-Congo hemorrhagic fever (CCHF) is a thick-borne viral zoonotic disease. The pathogenesis and the reasons why cases have a mild or severe course in CCHF have not yet been explained. In this study, we investigated the relationship between promoter -2518 A/G single-nucleotide polymorphism (SNP) of the MCP-1 gene and the clinical course of CCHF. The MCP-1-2518 A/G SNP (rs1024611) frequency was examined in 128 virologically/serologically confirmed CCHF patients and 181 healthy controls by using the PCR-RFLP method. When CCHF patients and controls were compared, no significant difference was found between genotype distributions and allele frequencies of the -2518 A/G SNP of MCP-1 gene (P > .05). Compared to the AA genotype, both AG (P = .016; OR = 2.57) and GG genotype (P = .039; OR = 3.43) were found with significantly higher frequencies in mild/moderate cases than in severe cases. Compared to the AG + GG genotype, AA showed a significant risk for severe CCHF (60.0% vs 38.4%, P = .02; OR = 2.41). In contrast, the AG genotype showed a significant protective effect against severe disease compared to AA + GG genotype (29.1% vs 47.9%, P = .013; OR = 2.58). Compared to mild/moderate cases, the A allele was found to be significantly higher in severe cases (0.745 vs 0.623, P = .039; OR = 1.77). However, no significant relationship was found between fatal and nonfatal cases in terms of genotype or allele frequencies (P > .05). In conclusion, both -2518 AA genotype and A allele of MCP-1 were associated with disease severity, and the AG genotype had a protective effect against a severe disease course in CCHF patients
Unusual manifestations of acute Q fever: autoimmune hemolytic anemia and tubulointerstitial nephritis
No full textQ fever is a worldwide zoonotic infection that caused by Coxiella burnetii, a strict intracellular bacterium. It may be manifested by some of the autoimmune events and is classified into acute and chronic forms. The most frequent clinical manifestation of acute form is a self-limited febrile illness which is associated with severe headache, muscle ache, arthralgia and cough. Meningoencephalitis, thyroiditis, pericarditis, myocarditis, mesenteric lymphadenopathy, hemolytic anemia, and nephritis are rare manifestations. Here we present a case of acute Q fever together with Coombs' positive autoimmune hemolytic anemia (AIHA) and tubulointerstitial nephritis treated with chlarithromycin, steroids and hemodialysis. Clinicians should be aware of such rare manifestations of the disease

This study aimed to characterize the current trend in a nationwide survey of ICUs in Turkey. Methods: A total of 88 ICUs from 36 Turkish tertiary hospitals were included in this retrospective study, which was performed during the first 3 months of both 2008 (period [P] 1) and 2011 (P2). A P value <=.01 was considered significant. Results: Although overall rates of hospital-acquired infection (HAI) and device-associated infection densities were similar in P1 and P2, the densities of HAIs due to S aureus and methicillin-resistant S aureus (MRSA) were significantly lower in P2 (P < .0001). However, the proportion of HAIs due to Acinetobacter was significantly higher in P2 (P < .0001). Conclusions: The incidence of S aureus infections is declining rapidly in Turkish ICUs, with potential impacts on empirical treatment strategies in these ICUs.
