Treatment of ventilator-associated pneumonia (VAP) caused by Acinetobacter: results of prospective and multicenter ID-IRI study.

Ventilator-associated pneumonia (VAP) due to Acinetobacter spp. is one of the most common infections in the intensive care unit. Hence, we performed this prospective-observational multicenter study, and described the course and outcome of the disease. This study was performed in 24 centers between January 06, 2014, and December 02, 2016. The patients were evaluated at time of pneumonia diagnosis, when culture results were available, and at 72 h, at the 7th day, and finally at the 28th day of follow-up. Patients with coexistent infections were excluded and only those with a first VAP episode were enrolled. Logistic regression analysis was performed. A total of 177 patients were included; empiric antimicrobial therapy was appropriate (when the patient received at least one antibiotic that the infecting strain was ultimately shown to be susceptible) in only 69 (39%) patients. During the 28-day period, antibiotics were modified for side effects in 27 (15.2%) patients and renal dose adjustment was made in 38 (21.5%). Ultimately, 89 (50.3%) patients died. Predictors of mortality were creatinine level (OR, 1.84 (95% CI 1.279-2.657); p = 0.001), fever (OR, 0.663 (95% CI 0.454-0.967); p = 0.033), malignancy (OR, 7.095 (95% CI 2.142-23.500); p = 0.001), congestive heart failure (OR, 2.341 (95% CI 1.046-5.239); p = 0.038), appropriate empiric antimicrobial treatment (OR, 0.445 (95% CI 0.216-0.914); p = 0.027), and surgery in the last month (OR, 0.137 (95% CI 0.037-0.499); p = 0.003). Appropriate empiric antimicrobial treatment in VAP due to Acinetobacter spp. was associated with survival while renal injury and comorbid conditions increased mortality. Hence, early diagnosis and appropriate antibiotic therapy remain crucial to improve outcomes.

Palliative care infections and antibiotic cost: a vicious circle.

Aim: In this study our aim was to evaluate the nosocomial infections and to understand factors affecting the cost of used antibiotics in palliative care unit.Materials and methods: Between 2016 and 2017, 113 patients were included in the study in palliative care unit of University of Health Sciences Bursa Yuksek Ihtisas Research and Training Hospital. Patients medical records were analyzed retrospectively for nosocomial infections, chronic diseases, presence of decubitis ulcers, opioid use, enteral, parenteral feedings, mortality and antibiotic cost.Results: Nosocomial infections were observed in 74.3% of the cases and 92.0% of patients used antibiotics. The mean duration of antibiotic use was 23.13 ± 18.06 days; and the average antibiotic cost was 2009.72 ± 2153.37 TL. Length of stay, male sex, presence of decubitus ulcers, tracheostomy, enteral and parenteral nutrition significantly increased antibiotic cost. Antibiotic cost and mortality were not related statistically.Conclusions: A vicious circle in palliative care involves the following order: length of stay, increased rate of infection, use of antibiotics, infection with resistant microorganisms, use of broad spectrum antibiotics, increased length of stay; all affecting each other. Therefore, using antibiotics for aggressive treatment of infections in palliative care is contraindicated as it opposes to real philosophy of palliative care.

Tetanus immunization among healthcare professionals: cross-sectional study in Turkey.

INTRODUCTION: Vaccine-preventable diseases can be effectively managed through timely vaccine booster doses. In this study, the tetanus vaccination status of healthcare professionals and their level of knowledge about tetanus vaccination were investigated. METHODOLOGY: The data were obtained through a survey questionnaire from 336 healthcare professionals. The survey participants were recruited on a voluntary basis among the personnel working in a tertiary hospital between 1 July 2021 and 30 September 2021. The participants were asked about their tetanus vaccination status and general awareness about the tetanus vaccine. RESULTS: The survey participants included nurses (41.4%, n = 139), doctors (39.9%, n = 134) and support unit personnel (18.8%, n = 63). The support unit personnel had insufficient knowledge about military service period, pregnancy period, vaccination of women aged 15-49 years, and the necessity of booster tetanus vaccine every 10 years. Interestingly, the nurses had significantly inadequate knowledge of geriatric tetanus vaccination. CONCLUSIONS: Although the tetanus immunization program is widely implemented throughout the country, our study concluded that it is necessary to educate healthcare professionals on the importance of the tetanus vaccine.

Evaluation of microbiological spectrum and risk factors of cellulitis in hospitalized patients.

BACKGROUND AND DESIGN: Cellulitis is a common soft tissue infection and the severity of disease vary from mild to life threatening. The aim of the present retrospective study was to evaluate age, sex, site of infection, microbiological spectrum and the risk factors of cellulitis in hospitalized patients. MATERIALS AND METHODS: The data were retrospectively obtained by the review of 185 hospitalized patients who were diagnosed as cellulitis between 2003 and 2009 in the departments of dermatology, infectious diseases, internal medicine and surgery clinics of Haydarpasa Numune Training and Research Hospital (Istanbul, Turkey). The diagnosis was done by infectious diseases and dermatology specialists in all patients who were included to this study. Demographic findings, wound-blood cultures and risk factors of the patients with cellulitis were evaluated. RESULTS: Eighty-six were female, 99 were male of total 185 patients, and the mean age of them was 48 ± 27 (14-85). The leg was the involved site in 69% of the patients. The most frequent isolated bacteria from wound cultures were methicillin-sensitive Staphylococcus aureus 31.5%, Pseudomonas aeruginosa 12.6%, and Escherichia coli 12.3%. However, methicillin-sensitive S. aureus 32.5%, methicillin-resistant S. aureus 22.5%, coagulase-negative staphylococci 17.5% were detected from blood cultures. There was not any underlying risk factor in 104 (55.3%) patients. The risk factors observed in the other 81 patients were previous surgery or open wound 29 (35.8%), diabetes mellitus 19 (26.6%), cardiovascular diseases 16 (19.7%), immunosuppression 11 (13.5%), lymphoedema 6 (7.4%). CONCLUSION: In the patients hospitalized for cellulitis, the most frequently isolated microorganism from the wound and blood cultures was S. aureus and the most frequently detected risk factors were to have an open wound and previous surgery. Especially when the patients had risk factors, it was observed that the bacterial spectrum was broader and the clinical presentation was severe. The wound and blood cultures should be performed simultaneously for the microbiological diagnosis and the appropriate management of cellulitis.

A snapshot of geriatric infections in Turkey: ratio of geriatric inpatients in hospitals and evaluation of their infectious diseases: A multicenter point prevalence study.

INTRODUCTION: The human population is aging at an astonishing rate. The aim of this study is to capture a situation snapshot revealing the proportion of individuals aged 65 years and over among inpatients in healthcare institutions in Turkey and the prevalence and type of infections in this patient group in order to draw a road map. MATERIALS AND METHODS: Hospitalized patients over 65 years at any of the 62 hospitals in 29 cities across Turkey on February 9, 2017 were included in the study. Web-based SurveyMonkey was used for data recording and evaluation system. RESULTS: Of 17,351 patients 5871 (33.8%) were ≥65 years old. The mean age was 75.1±7.2 years; 3075 (52.4%) patients were male. Infection was reason for admission for 1556 (26.5%) patients. Pneumonia was the most common infection. The median length of hospital stay was 5 days (IQR: 2-11 days). The Antibiotic therapy was initiated for 2917 (49.7%) patients at the time of admission, and 23% of the antibiotics prescribed were inappropriate. Healthcare-associated infections developed in 1059 (18%) patients. Urinary catheters were placed in 2388 (40.7%) patients with 7.5% invalid indication. CONCLUSION: This study used real data to reveal the proportion of elderly patients in hospital admissions. The interventions done, infections developed during hospitalization, length of hospital stay, and excessive drug load emphasize the significant impact on health costs and illustrate the importance of preventive medicine in this group of patients.

Diagnostic value of combined serum biomarkers for the evaluation of liver fibrosis in chronic hepatitis C infection: A multicenter, noninterventional, observational study.

BACKGROUND/AIMS: The hepatitis C virus (HCV) infection is important cause of chronic hepatitis. Liver biopsy is considered the gold standard for assessment of fibrosis but this procedure is an invasive procedure. We aimed to evaluate the diagnostic efficiency of non-invasive serum biomarkers, separately and in combinations, on liver fibrosis in treatment-naive chronic hepatitis C (CHC) patients. MATERIALS AND METHODS: Two hundred and sixteen treatment-naive CHC patients were enrolled from 32 locations across Turkey in this open-labelled, non-interventional prospective observational study. FibroTest®, aspartate aminotransferase-to-platelet ratio index(APRI), aspartate aminotransferase and alanine aminotransferase ratio (AAR), fibrosis index based on four factors (FIB-4), Age-platelet(AP) index and Forns index were measured and compared with Metavir scores got from liver biopsies. RESULTS: Data from 182 patients with baseline liver biopsy were suitable for analysis. One hundred and twenty patients (65.9%) had F0-F1 fibrosis and 62 patients (34.1%) had F2-F4 fibrosis. APRI 0.732 area under the curve(AUC) indicated advanced fibrosis with 69% sensitivity and 77% specificity. FIB-4 0.732 AUC and FibroTest 0.715 AUC indicated advanced fibrosis with 69% and 78.4% sensitivity, and 75% and 71.4% specificity, respectively. The combined use of tests also led to an increase in AUC and specificity. Combinations of FibroTest with APRI and/or FIB-4, and FIB-4 with APRI were optimal for the evaluation of liver fibrosis. CONCLUSION: Fibrotest, FIB-4, APRI, AP index and Forns index exhibit good diagnostic performance for determining liver fibrosis in CHC patients, and the use of at least two tests together will increase their diagnostic value still further.

Changes in acute viral hepatitis epidemiology in the Turkish adult population: A multicenter study.

BACKGROUND/AIMS: The present study aimed to determine the changes in the epidemiology of hepatitis in recent years in an adult Turkish population. MATERIALS AND METHODS: Overall, 852 patients with acute viral hepatitis from 17 centers were included in this study. Their sociodemographic characteristics, clinical courses, treatments, and laboratory findings were retrospectively analyzed. RESULTS: The most commonly found microorganisms were the hepatitis B virus (55.2%) and hepatitis A virus (37.6%), and the types of acute viral hepatitis differed significantly according to the age group (p≤0.001). The most frequently reported symptom was fatigue (73.7%), and the most common complications were cholecystitis (0.4%) and fulminant hepatitis (0.4%). The median hospital stay was 9 days (range 1-373). In total, 40.8% patients with acute hepatitis B virus developed immunity. CONCLUSION: In Turkey, there are significantly large adolescent and adult populations susceptible to acute viral hepatitis. Therefore, larger vaccination programs covering these age groups should be implemented.

Respiratory system involvement in brucellosis: the results of the Kardelen study.

BACKGROUND: Pulmonary involvement is a rare complication of brucellosis. We describe the largest series to date, to our knowledge, of patients with pulmonary brucellosis. METHODS: This 10-year, retrospective, descriptive study involved 27 centers in Turkey, including all patients with brucellosis with confirmed respiratory system involvement. RESULTS: Of 133 patients (67 men), 123 (92.5%) had acute infection (defined as < 2 months), with an overall mean ± SD duration of symptoms of 33.9 ± 8.5 days. The radiologic pattern of pulmonary disease was consolidation/lobar pneumonia in 91 patients (68.4%) and pleural effusion in 41 patients (30.8%), including 30 (22.5%) with both. Moreover, 23 patients (17.3%) had bronchitis (one with coexistent pneumonia), and 10 (7.5%) had nodular lung lesions (one with coexistent pneumonia and effusion). Blood culture results were positive in 56 of 119 patients, and all other cases were serologically confirmed. None of 60 sputum specimens and two of 19 pleural fluid samples (10.5%) yielded positive culture results for brucellosis. Other features of brucellosis, such as osteoarticular complications, were detected in 61 patients (45.9%); 59 (44.4%) had raised liver transaminase levels, and 59 (44.4%) had thrombocytopenia. Fifteen patients (11.3%) required management in an ICU for an average of 3.8 ± 2.2 days. All patients responded to standard combination antimicrobial therapy for brucellosis with no deaths, although treatment regimens required modification in seven patients. CONCLUSIONS: Brucellosis with pulmonary involvement is rare but has a good prognosis following treatment with appropriate antibiotics. Many clues in the exposure history, presenting clinical features, and baseline blood tests should alert the clinician to consider brucellosis.

Acute renal failure due to Brucella melitensis.

We present the case of a 42-year-old male patient who applied to the emergency department of our hospital with clinical nephritis, orchitis, acute renal failure without endocarditis, and a low-grade fever. Brucella agglutinin titers were 1:160, Rose Bengal test was positive and Brucella melitensis was isolated from urine and blood cultures.. A combination of oral rifampin (600 mg/day) and doxycycline (200 mg/day) was administered along with supportive treatment leading to resolution of his clinical status by eight weeks. This was a rare complication of severe renal involvement due to brucellosis which resolved with antibiotic treatment.
