Hand Hygiene Compliance in a Hematology Unit

Transmission of pathogens from the hands of health care workers (HCWs) is the main cause of nosocomial infections, and hand hygiene is the single most important procedure to prevent it. At present, little is known about the adherence of HCWs to hand hygiene procedures in hematology units, where the patients are at high risk for acquiring hospital infections. In a prospective observational study, two observers monitored the hand hygiene compliance of HCWs in a hematology unit during 30-min observation periods distributed randomly during the daytime over 2 months. The prevalence of compliance with hand hygiene was 26% on 638 observed occasions. The noncompliance was higher among nurses [odds ratio (OR) 3.52, 95% confidence interval (CI) 1.85–6.70] and other HCWs (OR 1.72, 95% CI 0.98–3.02) compared to physicians. The compliance rate differed from 4 to 60% depending on the activity. The lowest compliance rate (4%) was observed before patient care and the highest (60%) was after insertion of invasive devices. When we classified the occasions for hand hygiene into ‘before’ and ‘after’ activities, the compliance rates were 9 and 36%, respectively (OR 5.6, 95% CI 3.4–9.0). In conclusion, noncompliance with hand hygiene was high in this hematology unit, especially among nurses and before activities. Variations with the type of HCW and activity suggest that targeted educational programs and feedback control may be useful.

Successful Granulocyte Colony-stimulating Factor Treatment of Relapsing Candida albicans Meningoencephalitis Caused by CARD9 Deficiency.

Caspase-associated recruitment domain-9 (CARD9) deficiency is an autosomal-recessive primary immunodeficiency with genetic defects in Th17 immunity marked by susceptibility to recurrent and invasive Candida infections. We present a case of relapsing Candida albicans meningoencephalitis over 1-year period despite appropriate antifungal therapy. We detected a homozygous p.Q295X mutation in CARD9 as well as a defective interleukin-17 and interferon gamma synthesis in Enzyme-Linked ImmunoSpot tests. We achieved complete clinical remission, and improvement of interleukin-17 secretion with subcutaneous granulocyte colony-stimulating factor) treatment.

Can ratio of neutrophil-tolymphocyte count and erythrocyte sedimentation rate in diabetic foot infection predict osteomyelitis and/or amputation?

The aim of this study was to search for any relations between the neutrophil-to-lymphocyte ratio (NLR) and the development of osteomyelitis and the need for amputation in patients with diabetic foot infection (DFI). All data included DFI patients who were hospitalized in our Infectious Diseases Clinic between 2012 and 2015 and who were classified according to International Classification Disease Code System. 75 patients were analyzed in the study. The DFI patients were stratified into 3 groups of whom had amputation procedure, whom had only debridement/drainage procedure and whom had any surgery procedure. Sidac post hoc analysis was used to perform the effects of NLR, C-reactive protein, erythrocyte sedimentation rate and glycosylated hemoglobin on the surgery procedure status. The DFI patients were also stratified into two another separate group for another analysis to search for the effect of NLR values on the development of osteomyelitis. The mean value of NLR in the amputated patients’ group (15.7±10.3 was significantly higher than those with debridement procedure (9.9±5.6) and those without any surgery (6.0±2.8) (P=0.001). NLR values were also found significantly higher in patients with osteomyelitis in the second analysis (P=0.004). In this study, the NLR was found to have a predictive value on the development of osteomyelitis and on the progression to amputation in patients with DFI.

Evaluation of soluble CD200 levels in type 2 diabetic foot and nephropathic patients: Association with disease activity

Background CD200 (OX-2) is a novel immune-effective molecule, existing in a cell membrane-bound form, as well as in a soluble form in serum (s OX-2), which acts to regulate inflammatory and acquired immune responses. Material/Methods We planned this study to evaluate the sOX-2 levels of type 2 diabetic foot (group B), and compare it with that of healthy controls (group A). The patient group had the following values: DM period: 27.9±10.3 year [mean ±SD], HbA1c: 9.52±2.44% [mean ±SD]. Results Blood samples for sCD200 measurement were always taken in the morning between 8 and 10 A.M.. The results were reported as means of duplicate measurements. Concentrations of sOX-2 in the serum samples were quantified using an ELISA kit. Serum hs-CRP levels were measured using an hs-CRP assay kit. The sOX-2 level in group B was 173.8±3.1 and in group A was 70.52±1.2 [p<0.0001). In subgroup analysis of T2DM-DFI patients, we noticed that sOX-2 levels were higher in WGS (Wagner grading system) I and II patients than in WGS III and IV patients. The HbA1c, BUN, creatinine, hs-CRP levels, and sedimentation rates were higher in the patient group (p<0.0001, p<0.001, p<0.001, p<0.005, and p<0.0001, respectively). Conclusions We suggest that there are vascular, immunologic, and neurologic components in DFI, whereas autoimmune diseases and inflammatory skin disorders have only an immunologic component. This is possibly evidence of a pro-inflammatory effect seen in DFI as a vascular complication.

Un brote epidémico de endocarditis por Pseudomonas aeruginosa secundario a angiografía coronaria

OBJECTIVES To describe an endocarditis outbreak affecting three patients due to Pseudomonas aeruginosa infection post coronary angiography performed in the Cardiovascular Surgery and Cardiology Medical Center of a private hospital. METHODS After recognition of an infection cluster within a onemonth period, the outbreak was reported to Antalya Department of Health and a broad investigation was initiated in order to determine the most probable cause and/or source of nosocomial pseudomonal endocarditis. Patient data were obtained by medical record review as well as interviews with patients or their next of kin. Thirty-six surveillance samples for P. aeruginosa were collected from various locations within the coronary angiography unit. The outbreak research team reviewed the private hospitals Cardiovascular Surgery and Cardiology Medical Centers infection control procedures. The epidemiology of P. aeruginosa was studied through analysis of phenotypic markers, including antimicrobial sensitivity profiles. RESULTS The infection control audit revealed multiple breaches of infection control procedures. Only 1/36 environmental samples yielded, which was isolated from a radio-opaque solution within an angiography injector pump. P. aeruginosa from the radio-opaque solution had an identical antimicrobial susceptibility pattern to the strain isolated from patients. Both samples were susceptible to all antipseudomonal agents. This outbreak could have been successfully controlled by instituting combined infection control measures. CONCLUSIONS This outbreak emphasizes the important of adherence to infection control standards and practices for cardiac catheterization, as well as the need for closer collaboration between the Infection Control Committee and coronary angiography personnel.

Evaluation of sOX-2 levels in type2 diabetic foot and nephropathic patients: association with disease activity

Background OX-2 is a member of the immunoglobulin supergene family of receptors . sOX-2 was originally described as a myeloid receptor, being expressed on macrophages, granulocytes and dendritic cells, and also expressed on T cells, Bcells, and natural killer cells. It displays a restricted tissue distribution, including activated T and B cells. sOX-2 is induced by inflammatory cytokines, including TNFand bindsto OX-2 receptor.We evaluated other biomarkers like high-sensitivity CRP(hs-CRP) in DFI patients to compare with that of healthy controls. Possible correlationswere investigated between these markers and creatinine levels, Wagner grading system (WGS), and body mass index(BMI), as well as sedimentation rate, preprandial glucose levels, and age.

Successful use of tigecycline for treatment of culture-negative pyogenic vertebral osteomyelitis

Abstract Background: Pyogenic vertebral osteomyelitis (PVO) is a severe infection that requires prolonged antimicrobial therapy and/or surgical interventions. Limited data are available on the safety and clinical efficacy of tigecycline in PVO. The objective of this study was to describe the clinical outcomes of patients treated with tigecycline for culture-negative PVO that was unresponsive to empirical antibiotic therapy including intravenous ampicillin-sulbactam plus ciprofloxacin or ampicillin-sulbactam alone. Methods: We retrospectively reviewed 15 patients with culture-negative PVO from 2009 through 2014. The patients received tigecycline as secondary empirical therapy, after not responding to the first empirical therapy. Clinical success was defined as recovery from symptoms and normalization of laboratory parameters at the end of therapy. Continued clinical success at 24 weeks after the end of the therapy was defined as sustained clinical success. Results: Tigecycline treatment was completed in 14 patients and discontinued in 1 due to severe nausea and vomiting. The mean age of the patients was 67.7 years (range 58–77 years), and 57.1% (8/14) were women. In all, 78.6% (11/14) of patients had risk factors for probable resistant staphylococcal and gram-negative infections such as diabetes mellitus, presence of hemodialysis catheters, and prior antibiotic usage. The average duration of tigecycline treatment was 8.3 weeks (range 6–11 weeks). Sustained clinical success was obtained in all patients. Conclusions: Tigecycline should be considered as an alternative agent for the treatment of PVO in selected patients due to microbiological activity against resistant gram-positive and gram-negative bacteria.

Weekly chlorhexidine douche: does it reduce healthcare-associated bloodstream infections?

Abstract Background: Daily chlorhexidine (CHG) bathing has been used as a precaution to reduce the rate of healthcare-associated bloodstream infections (HA-BSI). The application frequency of CHG bathing remains unclear, this procedure has been implemented daily by this time. The aim of this study was to determine the efficacy of weekly whole-body douche with CHG shower gel on rates of HA-BSI. Methods: We conducted a prospective intervention trial in medical, surgical, and anesthesiology intensive care units (ICUs) in a tertiary teaching hospital from June 2011 to November 2012. This study included three periods. During the first period, patients received a daily bed bath by wiping with water and soap. In the second period patients were given a weekly douche with water and soap; in the third period patients were given a weekly douche with CHG shower gel. The rates of HA-BSI were compared between the three periods using Poisson regression analysis. Results: The central line-associated bloodstream infection rates did not decline significantly between periods (p = 0.76). The laboratory-confirmed bloodstream infection (LCBSI) rates in the first, second, and third periods were 7.1, 4, and 1.7, respectively. The LCBSI rates were reduced 43.7% from the first period to the second period (p = 0.03). In addition, there was a 57.5% reduction in LCBSI rates between the second and third periods (p < 0.001). Interestingly, the major decline (76.1%) was determined from the first to the third period (p < 0.002). Conclusions: Weekly douche with CHG shower gel significantly reduced LCBSI rates. Further studies are needed to validate the clinical impact of different intervals of CHG bathing.

Circulating apo 2L levels decreased in hepatitis C with the pegilated interferon-2 alpha treatment

Background Chronic hepatitis C (HCV) infects approximately 170 million people and causes more than 350 000 deaths every year. Information regarding pathogenetic mechanism of acute hepatitis C infection is limited. Following innate immune activation, cellular immunity, including natural killer (NK) cell activation and antigen-specific CD8 cell proliferation occurs. CD8+ T lymphocytes directly kill infected cells via direct cell-cell contact, and release antiviral cytokines (e.g. IFN, TNF)

Plasmodium falciparum Malaria and Exchange Transfusion Application

Malaria caused by P. falciparum, is endemic in tropical and subtropical areas but is seen as sporadic cases in our country. A patient, early diagnosed and succesfully treated with antimalarial drug administration and a patient, with severe clinical manifestations and succesfully treated with antimalarial medication as well as Erythrocyte Exchange Transfusion (EET), who were not applied chemoprophylaxis are presented. The cases are presented in order to emphasize on the necessity of giving education to the people going to endemic areas from our country for work or travel and on the necessity of taking chemoprophylaxis and to take attention that EET may be preffered in the therapy of severe malaria cases.
