RESUMEN

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 (junior specialists = JSs) and 942 (49.4%) of them were physicians. Specialists having >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.

RESUMEN

BACKGROUND: Brucella melitensis and B. abortus are the species generally isolated from human samples in Turkey. Several studies have also demonstrated the presence of antibodies against B. canis. CASE REPORT AND STUDY: Brucella spp. was isolated from blood culture from a 35-year-old male with clinical signs and symptoms of acute meningitis, including fever lasting for 1 week. Multiplex PCR demonstrated B. suis, and biochemical features indicated biovar 1. CONCLUSIONS: This report is the first emphasizing that B. suis should be considered among the causes of brucellosis in Turkey.

RESUMEN

AIM: Clinical practice guidelines for the management of diabetic foot infections developed by the Infectious Diseases Society of America (IDSA) are commonly used worldwide. The issue of whether or not these guidelines need to be adjusted for local circumstances, however, has seldom been assessed in large prospective trials. METHODS: The Turk-DAY trial was a prospective, multi-center study in which infectious disease specialists from centers across Turkey were invited to participate (NCT02026830). RESULTS: A total of 35 centers throughout Turkey enrolled patients in the trial. Overall, investigators collected a total of 522 specimens from infected diabetic foot wounds for culture from 447 individual patients. Among all isolates, 36.4% were gram-positive organisms, with Staphylococcus aureus the most common among these (11.4%). Gram-negative organisms constituted 60.2% of all the isolates, and the most commonly isolated gram-negative was Escherichia coli (15%). The sensitivity rates of the isolated species were remarkably low for several antimicrobials used in the mild infection group. CONCLUSIONS: Based on our findings, several of the antimicrobials frequently used for empirical treatment, including some also recommended in the IDSA guidelines, would not be optimal for treating diabetic foot infections in Turkey. Although the IDSA guideline recommendations may be helpful to guide empiric antimicrobial therapy of DFIs, they should be adjusted to local conditions.

RESUMEN

OBJECTIVES: To compare the efficacy of colistin (COL) monotherapy versus non-COL based combinations in the treatment of bloodstream infections (BSIs) due to multidrug resistant Acinetobacter spp.(MDR-A). MATERIALS AND METHODS: Retrospective data of 107 MDR-A BSI cases from 27 tertiary centers in Turkey were included. PRIMARY END-POINT: 14-day mortality. SECONDARY END-POINTS: Microbial eradication and clinical improvement. RESULTS: Thirty-six patients in the COL monotherapy (CM) group and 71 in the non-COL based combinations (NCC) group were included in the study. Mean age was 59.98 ± 20 years (range: 18-89) and 50.5% were male. Median duration of follow-up was 40 days (range: 9-297). The 14-day survival rates were 52.8% in CM and 47.23% in NCC group (P = 0.36). Microbiological eradication was achieved in 69% of CM and 83% of NCC group (P = 0.13). Treatment failure was detected in 22.9% of cases in both CM and NCC groups. Univariate analysis revealed that mean age (P = 0.001), Charlson comorbidity index (P = 0.03), duration of hospital stay before MDR-A BSI (P = 0.04), Pitt bacteremia score (P = 0.043) and Acute Physiology and Chronic Health Evaluation II score (P = 0.05) were significant in terms of 14-day mortality. Advanced age (P = 0.01) and duration of hospital stay before MDR-A BSI (P = 0.04) were independently associated with 14-day mortality in multivariate analysis. CONCLUSION: No significant difference was detected between CM and non-COL based combinations in the treatment of MDR-A BSIs in terms of efficacy and 14-day mortality.

RESUMEN

INTRODUCTION: There is limited data in the literature about brucellosis related to an intracellular pathogen and anti-tumor necrosis factor alpha (anti-TNFα) medication. The aim of this study was to evaluate acute Brucella infections in mice receiving anti-TNFα drug treatment. METHODOLOGY: Anti-TNFα drugs were injected in mice on the first and fifth days of the study, after which the mice were infected with B. melitensis M16 strain. Mice were sacrificed on the fourteenth day after infection. Bacterial loads in the liver and spleen were defined, and histopathological changes were evaluated. RESULTS: Neither the liver nor the spleen showed an increased bacterial load in all anti-TNFα drug groups when compared to a non-treated, infected group. The most significant histopathological findings were neutrophil infiltrations in the red pulp of the spleen and apoptotic cells with hepatocellular pleomorphism in the liver. There was no significant difference among the groups in terms of previously reported histopathological findings, such as extramedullary hematopoiesis and granuloma formation. CONCLUSIONS: There were no differences in hepatic and splenic bacterial load and granuloma formation, which indicate worsening of the acute Brucella infection in mice; in other words, anti-TNFα treatment did not exacerbate the acute Brucella spp. infection in mice.

RESUMEN

INTRODUCTION: Cystic echinococcosis (CE) is a serious public health problem in sheep-raising regions of Turkey. The aim of this study was to determine the prevalence and associated risk factors of echinococcosis in rural regions of Denizli in Turkey. METHODOLOGY: This study was undertaken in four townships in Denizli County between May 2009 and July 2009. Family members were interviewed to assess possible risk factors for infection and tested for anti-E. granulosus antibodies by enzyme-linked immunosorbent assay (ELISA). RESULTS: Of the 1,133 individuals included in the study, 78 (6.9%) were found to be anti-EG seropositive. Multivariate analysis showed that the 30-39 year age group (odds ratio [OR]: 3.29; 95% confidence interval [CI]: 1.30 ± 8.33; p = 0.01), the ≥ 60 year group (OR: 4.08; 95% CI: 1.57 ± 10.61; p = 0.004), and the group that reported sometimes or never getting veterinary care for their animals (OR: 1.75; 95% CI: 1.05 ± 2.93; p = 0.032) had higher rates of seropositivity. Multivariate analysis showed that education was not significantly associated with seropositivity. Furthermore, no significant correlation with location, occupation, dog ownership or contact with dogs, or with cattle and/or sheep/goat ownership was found. Regular veterinary care and education had significant effects on lowering the prevalence of CE. CONCLUSIONS: Our results suggest that preventive measures, such as regular veterinary care for animals and educative and supportive activities oriented to the people working in farming and animal husbandry should be taken to decrease the prevalence of human CE in Turkey.

RESUMEN

Veterinarians and veterinary technicians are at risk for occupational brucellosis. We described the risk factors of occupational brucellosis among veterinary personnel in Turkey. A multicenter retrospective survey was performed among veterinary personnel who were actively working in the field. Of 712 veterinary personnel, 84 (11.8%) had occupational brucellosis. The median number of years since graduation was 7 (interquartile ranges [IQR], 4-11) years in the occupational brucellosis group, whereas this number was 9 (IQR, 4-16) years in the non-brucellosis group (p<0.001). In multivariable analysis, working in the private sector (odds ratio [OR], 2.8; 95% confidence interval [95% CI], 1.55-5.28, p=0.001), being male (OR, 4.5; 95% CI, 1.05-18.84, p=0.041), number of performed deliveries (OR, 1.01; 95% CI, 1.002-1.02, p=0.014), and injury during Brucella vaccine administration (OR, 5.4; 95% CI, 3.16-9.3, p<0.001) were found to be risk factors for occupational brucellosis. We suggest that all veterinary personnel should be trained on brucellosis and the importance of using personal protective equipment in order to avoid this infection.

RESUMEN

INTRODUCTION: Duration of treatment of asymptomatic bacteriuria for patients undergoing urologic surgical procedures is undetermined. We compared the efficacy of long- versus short-course antimicrobial treatment in patients with asymptomatic bacteriuria undergoing urologic surgical procedures. METHODOLOGY: Patients were divided into two groups according to duration of antimicrobial treatment. Group A patients received a single dose of an appropriate antibiotic, determined by antimicrobial sensitivity testing, 30 to 60 minutes before the surgical procedure. If a urinary catheter was placed postoperatively, a second dose was given following the recommended dose interval. Group B patients received antimicrobial treatment prior to surgery at least until patient urine became sterile. All patients were monitored for signs and symptoms of septicemia following surgical procedures. RESULTS: None of the patients enrolled in the study developed infectious complications such as sepsis or upper urinary tract infection. In group A, 31 patients were treated with antimicrobials before 39 urological procedures. In group B, the mean treatment time for 28 patients before 30 urological procedures was 8.03 ± 3.86 days. There were also significant differences in length of stay and the cost of antimicrobial therapy between the groups (P < 0.0001). Isolation of an increased number of resistant microorganisms was associated with long course therapy in group B. CONCLUSIONS: Short course therapy protocol may be a practical, simple approach for antibiotic use; it decreases hospital stays, eliminates delayed procedure times, lowers the economic cost of antimicrobials and lessens the chance of superinfection with and spread of antimicrobial resistant microorganisms.

RESUMEN

OBJECTIVE: To evaluate quality of perioperative antibiotic prophylaxis (PAP) and to calculate the cost per procedure in a Turkish university hospital. SETTING: A 352-bed teaching hospital in Denizli, Turkey. METHOD: An prospective audit was performed between July and October 2010. All clean, clean-contaminated and contaminated elective surgical procedures in ten surgical wards were recorded. Antimicrobial use was calculated per procedure using the ATC-DDD system. The appropriateness of antibiotic use for each procedure was evaluated according to international guidelines on PAP. In addition, the cost per procedure was calculated. RESULTS: Overall, in 577 of the 625 (92.3%) of the studied procedures, PAP was used. PAP was indicated in 12.5% of the group where it was not used, and not indicated in 7.1% of the group where it was used. Unnecessarily prolonged antimicrobial prophylaxis was observed in 56.9% of the procedures, mean duration was 2.6 ± 2.7 days. The most frequently used antimicrobials were cefazolin (117.9 DDD/100-operation) and sulbactam/ampicillin (102.2 DDD/100-operation). The timing of the starting dose was appropriate in 545 procedures (94.5%). In the group that received PAP, only 80 (13.7%) of the procedures were found to be fully appropriate and correct. The density of antimicrobial use per operation was 2.8 DDD. The mean cost of the use of prophylactic antimicrobials 18.6 per procedure. CONCLUSION: The density of antimicrobial use in PAP was found to be very high in our hospital. Antibiotic overuse extended into the postoperative period.

RESUMEN

BACKGROUND: Diabetes mellitus is a risk factor for methicillin-resistant Staphylococcus aureus (MRSA) colonization and infection. We attempted to determine the prevalence and risk factors for MRSA colonization in a population of outpatients with diabetes. METHODS: This prospective cohort study enrolled patients with diabetes. Anterior nares cultures were obtained from patients with diabetes admitted to outpatient endocrinology and metabolism clinics, and risk factors for MRSA colonization were analyzed. RESULTS: Out of the 304 patients evaluated, 127 (41.9%) were colonized with S aureus and 30 (9.9%) were colonized with MRSA. Overall, 23.6% of all S aureus isolates were MRSA. In multivariate analysis, factors independently associated with an increased risk of MRSA colonization included the presence of connective tissue disease (odds ratio, 7.075; 95% confidence interval, 2.157-23.209; P = .001) and insulin therapy (odds ratio, 3.910; 95% confidence interval, 1.652-9.251; P = .002). CONCLUSIONS: The prevalence of MRSA colonization in our sample of diabetic outpatients was 9.9%. Independent risk factors for MRSA colonization were the presence of connective tissue disease and insulin use. A better understanding of the epidemiology and risk factors for nasal MRSA colonization in the persons with diabetes may have significant implications for the treatment and prevention of MRSA infections.

RESUMEN

Blood-borne pathogens (BBP) represent remarkable occupational risks for healthcare workers (HCWs). Avoiding occupational blood exposure is a basis of prevention of the blood-borne pathogens (BBP). The effectiveness of the prevention strategies depends on the compliance and adherence to the program by healthcare-facility personnel. The aim of this study was to evaluate Turkish HCWs' compliance with Universal Precautions (UP). An analytic, cross-sectional, countrywide survey study was performed in hospital settings, (n = 5145) in 30 hospitals in 19 cities. In total, 1726 of the 5143 (33.6%) participants' behaviors were accepted as satisfactory for compliance with UP. The hepatitis knowledge levels of 2,650 (51.5%) participants were found to be satisfactory. In the multivariate analysis, working at a surgical site (P = 0.004), living in a rich region (P = .007) and the existence of a health office for HCWs (p = .000) were found to be contributor factors for HCWs' compliance with UP. Conversely, being a nurse (P = .000) and HBV/HCV carrier status (P = .039) were significant preventing predictors for HCWs' compliance with UP. Along with the other well-known predictive factors, regional economic status and a health office for HCWs are contributors for compliance with UP.

RESUMEN

BACKGROUND: This study was conducted to evaluate the epidemiology of percutaneous injury and/or mucosa exposure (PME) with blood or other body fluids that poses serious risks for health care workers (HCWs). METHODS: An analytic, cross-sectional, countrywide survey study was conducted to describe the extent of and predictive factors for PME among HCWs in hospital settings in Turkey, with total of 5258 HCW participants from 30 hospitals in 19 cities throughout the country. RESULTS: The respondent group included 41.3% nurses, 29.0% doctors, 9.3% laboratory workers, and 20.3% paramedics. The survey found that 50.1% of the participants reported at least 1 occupational PME in the previous year. Doctors (2.57/person/year) and nurses (2.56/person/year) had the highest PME incidents. In the multivariate analysis, working at a surgical site (P = .000), being a doctor (P = .000), being a nurse (P=.000), young age (P = .025), and living in a poor region (P = .005) were significant factors for high occupational exposure. The presence of a health office for HCWs at the hospital (P = .000) and working at a university hospital (P = .003) were significant predictors of less occupational exposure. Overall, the mean number of PME incidents was 2.16/person/year. CONCLUSION: Along with the other well-known predictive factors, regional economic status and a health office for HCWs are preventive factors for PME exposure of HCWs.

RESUMEN

OBJECTIVE: To assess the perioperative antibiotic prophylaxis (PAP) prescriptions in a general hospital, Diyarbakir, Turkey. METHOD: An evaluative audit in a prospective cohort included into the study between February and June 2003. All clean and clean-contaminated elective surgical procedures in six surgical wards were recorded. Using the ATC-DDD system, density of antimicrobial use was calculated per procedure. RESULTS: Totally 331 of 391 (84.7%) study procedures received PAP. PAP was indicated in 45% of PAP non-received group and not indicated in 15.1% of received group. Only 18.4% of PAP lasted less than 24 h. The most common prescribed agents were the first generation cephalosporins (85.8%) and aminoglycosides (24.2%). Timing of the initial dose was inappropriate in 135 procedures (40.8%). Only in 44 procedures (13.3%) all steps of PAP were found justified and correct in PAP received group. The mean dosage number of PAP (+/-SD) for per operation was 8.7 +/- 12.5. The density of antimicrobial use was calculated as 330.2 DDD/100-operation. The density of antimicrobial use per operation was 3.3 DDD. CONCLUSION: The density of antimicrobial use in PAP is very high. To improve the appropriateness of PAP, measure of antibiotic use is urgently required.

RESUMEN

BACKGROUND: The Widal test is the most common, specific and quick diagnostic method available in the world for diagnosis of typhoid fever; however, false negativity is one of the obstructive features of the test. The aim of this study was to evaluate the associated factors with Widal test negativity in an endemic area. METHODS: Widal test negativity was retrospectively analyzed among culture-proven typhoid fever cases. The potential features including age, gender, previous antibiotic usage, duration of symptoms, leucopoenia, hematocrit value, and erythrocyte sedimentation rate (ESR) were evaluated for association with Widal test negativity. RESULTS: A total of 166 culture-proven typhoid fever cases (93 or 56.0% males) were included in the study. The mean age +/- SD was 23.3 +/- 10.6 years. Mean time of interval between first symptom and test performance time was 10.6 +/- 7.8 days. The Widal test (STO and/or STH) was found positive in 75 cases (45.2%). The statistical analyses revealed that none of these variables were significant for false negativity of the Widal test. Age was found to be a possible factor for a false negative Widal test (p=0.06). CONCLUSION: Of existing compatible clinical findings, age should be considered in cases of Widal test negativity.

RESUMEN

The goal of this study was to develop a simple prediction rule for the diagnosis of typhoid fever. A model for the prediction of patients with typhoid fever at hospital admission was derived and validated by assigning weighted point values to independent predictive factors associated with a diagnosis of typhoid fever at hospital admission. Patient demographic, clinical and laboratory variables were used to compare patients with blood culture-confirmed typhoid fever with patients with fever of unknown origin. The model was derived and validated in two separate cohorts of patients from Dicle University Hospital in Diyarbakir, Turkey. A total of 371 patients were enrolled. A diagnostic index score was created using seven independent predictive factors associated with typhoid fever at hospital admission: age <30 years, abdominal distention, confusion, leukopenia, relative bradycardia, positive Widal test and a typhoid tongue. A clinical prediction rule helped to differentiate patients with typhoid fever.

RESUMEN

This prospective study was carried out in two university hospitals between January 2000 and December 2002. The diagnosis of brucellosis was made with compatible clinical findings, positive Brucella agglutination > or =1/160 titres, and/or the isolation of Brucella species. The patients were followed up without intervention. One hundred and thirty-eight patients with active brucellosis were evaluated. Of the participants, 79 (57.2%) cases were acute, 23 (16.7%) sub-acute and 36 (26.1%) chronic. Brucella melitensis was isolated in the specimens of 24 (26.9%) out of 89 patients. The most frequent symptoms were fever (78.3%), arthralgia (77.5%) and sweating (72.5%). The most common physical findings were fever (40.6%), splenomegaly (36.2%), and hepatomegaly (26.8%). The osteoarticular involvement was found in 64 patients (46.4%). Ten (7.5%) patients had orchiepididymitis. Meningitis, pulmonary involvement, endocarditis, and hepatitis were found in five (3.6%), three (2.1%), two (1.5%) and one (0.7%) patient, respectively. Relative lymphomonocytosis was found in 80 cases (58.8%), anaemia in 46 (33.3%) and leucopoenia in 30 cases (21.7%). Clinical relapse was observed in 14 patients (10.1%).

RESUMEN

BACKGROUND: Tuberculosis (TB) is an important problem among health care workers (HCWs), both in Turkey and in other countries. The purpose of this study was to determine the risk ratio and features of tuberculosis (TB) among health care workers (HCWs) at a teaching hospital in southeast Turkey. METHODS: In a hospital-wide study at Dicle University Hospital, a referral center in southeast Turkey, data from HCWs with TB were collected from clinic and hospital records. The incidence and relative risk (RR) of TB among HCWs between 1986 and 2000 were analyzed and evaluated retrospectively according to TB incidence in the general population of Turkey. RESULTS: In this 15-year period, there were 22 HCWs with pulmonary tuberculosis (9 men, 13 women; 4 doctors, 13 nurses, 5 paramedics) out of an average of 734 workers per year over the study period. The mean age of the doctors was 27.1 years; nurses, 20.6 years; and paramedics, 30.5 years. The mean working experience of HCWs was 3.5 years (2.8 years for doctors, 2.8 years for nurses, 6.4 years for paramedics). The mean incidence of TB among the general population of Turkey between 1986 and 2000 was 40.8 of 100,000 persons. The mean incidence of tuberculosis in all HCWs of the hospital was 199.9 of 100,000 persons (RR = 4.9), 127.1 of 100,000 persons in doctors (RR = 3.1), 274.4 of 100,000 persons in nurses (RR = 6.7), and 160.2 of 100,000 persons (RR = 3.9) in paramedics. CONCLUSION: Hospital acquired tuberculosis is prominent among young nurses who work in high-risk departments.

RESUMEN

A case-control study was performed using the records of patients hospitalized for typhoid fever at Dicle University Hospital, Diyarbakir, Turkey, between 1994 and 1998. Case patients with enteric perforation were compared with control patients with typhoid fever but no enteric perforation. Risk factors for perforation were determined using logistic regression modeling. Forty case patients who had surgery because of typhoid enteric perforation were compared with 80 control patients. In univariate analyses, male sex (p = 0.01), age (p = 0.01), leukopenia (p = 0.01), inadequate antimicrobial therapy prior to admission (p = 0.01), and short duration of symptoms (p = 0.01) were significantly associated with perforation. In multivariate analysis, male sex (odds ratio (OR) = 4.39, 95% confidence interval (CI): 1.37, 14.09; p = 0.01), leukopenia (OR = 3.88, 95% CI: 1.46, 10.33; p = 0.04), inadequate treatment prior to admission (OR = 4.58, 95% CI: 1.14, 18.35; p = 0.03), and short duration of symptoms (OR = 1.22, 95% CI: 1.10, 1.35; p = 0.001) were significant predictors of perforation. A short duration of symptoms, inadequate antimicrobial therapy, male sex, and leukopenia are independent risk factors for enteric perforation in patients with typhoid fever.

RESUMEN

OBJECTIVE: Risk factors of catheter-related bloodstream infection (CR-BSI) caused by central venous catheter (CVC) use at a university hospital were evaluated. DESIGN: A prospective, observational, hospital-wide study was conducted. SETTING: The study was conducted at a university hospital with 1050 beds. METHODS: Nontunneled catheters were used, and double or triple lumen was observed. Catheters were cultured by semi-quantitative method, and blood cultures were performed if necessary. All epidemiologic and clinical data were recorded without intervention during the study. RESULTS: Over a 1-year period, the study assessed 389 CVCs inserted in 367 patients (mean age 50.9 +/- 18.1 years; 215 [58.6%] men, 152 [41.4%] women). Duration of catheterization was 12.0 +/- 9.9 days. CVCs were inserted into either the subclavian vein (N=263; 67.6%) or the jugular vein (N=128; 32.4%). In 250 episodes (64.3%), antibiotics were used concomitantly. CR-BSI was found in 43 of all CVCs (11.1%). The rate of CR-BSI per 1000 catheter-days was 9.21 for the whole cohort. In multivariable analysis, only renal failure (OR 4.83; CI 1.32-17.66; P=.017) was found to be a risk factor for CR-BSI. CONCLUSION: Renal failure was an independent risk factor for CR-BSI.

RESUMEN

The risk of transmission of hepatitis C virus (HCV) infection is an important problem for the health care worker. HCV transmission by blood splashing into eyes is very rare. In a hemodialyses department, a 23-year-old female nurse splashed blood from a patient who was anti-HCV positive into her eyes. She washed her eyes with water immediately and reported to the infection control department. She had never used intravenous drugs nor received transfusions. At the time of exposure, there was no abnormality in her laboratory tests. Her anti-HCV and HCV-RNA tests produced negative results. She was followed up for anti-HCV and alanine aminotransferase activity. After 6 months, she presented with sore throat, nausea, vomiting, fatigue, and weight loss. She had icterus and hepatomegalia. In laboratory tests, alanine aminotransferase level was 504 U/L, aspartate aminotransferase level was 388 U/L, and anti-HCV and HCV-RNA tests produced positive findings. She was treated with interferon alfa-2a for a 1-year period. After treatment, an HCV-RNA test produced negative results and transaminase levels were normal. In conclusion, splashing blood from patients who are HCV positive into the face or eyes is a risk for health care workers. They should be educated to prevent a nosocomial acquisition of bloodborne infection and they should observe protective precautions.
