Tetanus in adults: results of the multicenter ID-IRI study.

Tetanus is an acute, severe infection caused by a neurotoxin secreting bacterium. Various prognostic factors affecting mortality in tetanus patients have been described in the literature. In this study, we aimed to analyze the factors affecting mortality in hospitalized tetanus patients in a large case series. This retrospective multicenter study pooled data of tetanus patients from 25 medical centers. The hospitals participating in this study were the collaborating centers of the Infectious Diseases International Research Initiative (ID-IRI). Only adult patients over the age of 15 years with tetanus were included. The diagnosis of tetanus was made by the clinicians at the participant centers. Izmir Bozyaka Education and Research Hospital's Review Board approved the study. Prognostic factors were analyzed by using the multivariate regression analysis method. In this study, 117 adult patients with tetanus were included. Of these, 79 (67.5%) patients survived and 38 (32.5%) patients died. Most of the deaths were observed in patients >60 years of age (60.5%). Generalized type of tetanus, presence of pain at the wound area, presence of generalized spasms, leukocytosis, high alanine aminotransferase (ALT) and C-reactive protein (CRP) values on admission, and the use of equine immunoglobulins in the treatment were found to be statistically associated with mortality (p < 0.05 for all). Here, we describe the prognostic factors for mortality in tetanus. Immunization seems to be the most critical point, considering the advanced age of our patients. A combination of laboratory and clinical parameters indicates mortality. Moreover, human immunoglobulins should be preferred over equine sera to increase survival.

Piperacillin/tazobactam vs. cefoperazone/sulbactam in adult low-risk febrile neutropenia cases.

AIM: The aim of this study was to compare the efficacy of piperacillin/tazobactam (P/T) and cefoperazone/sulbactam (C/S) in the empirical treatment of adult neutropenic fever. METHODS: Data and outcomes of low-risk adult cases with neutropenic fever and treated with P/T (4.5 g q6h) or C/S (2 g q8h) between 2005 and 2011 June were extracted from our database. Risk evaluation was made according to criteria of Multinational Association for Supportive Care in Cancer (MASCC) and a score of ≥ 21 was considered as low risk. Data were collected prospectively by daily visits and evaluated retrospectively. Primary outcome was - fever defervescence at 72 h in combination with success without modification (referring to episodes where the patient recovered from fever with disappearance of signs of infection without modification to initial empirical treatment). All-cause mortality referred to death resulting from a documented or presumed infection or unidentified reason during the treatment and 30-day follow-up period. RESULTS: A total of 172 patients (113 cases P/T and 59 cases C/S) fulfilled the study inclusion criteria. Persistent response in P/T arm was 73.5%, whereas it was 64.5% in C/S arm (p > 0.05). Rates of any modification were also similar in both treatment arms. All-cause mortality during the treatment and 30-day follow-up period was not significantly different (P/T: 4/113 vs. C/S: 2/59, p > 0.05). There was no severe adverse effect requiring antibiotic cessation in both cohorts. CONCLUSION: In conclusion, our data suggest that C/S may be a safe alternative to P/T in the empirical treatment of adult low-risk febrile neutropenia cases.

Nursing students' immunisation status and knowledge about viral hepatitis in Turkey: a multi-centre cross-sectional study.

BACKGROUND: The aims of this multi-centre cross-sectional survey were to detect Turkish nursing students' level of knowledge on viral hepatitis, to evaluate their rates of exposure to blood and to find out their hepatitis A (HAV), hepatitis B (HBV) vaccination status. METHODS: This multi-centre cross-sectional study was conducted in 14 nursing schools located in the seven geographical regions of Turkey. A questionnaire composed of 47 questions on socio-demographic factors, level of knowledge on HAV, HBV, hepatitis C (HCV) immunisation status, exposure history and attitudes was applied to the study group. RESULTS: A total of 1491 third- and fourth-year nursing students participated with an 89% response rate. The mean age of the participating students was 21.4 ± 1.3. Their mean knowledge score was 23.7 ± 4.6 (71/100) and was significantly higher in fourth-year students than third-year students. There were significant differences in mean scores among nursing schools. Among the participants, 85.3% had received HBV vaccine and 9.1% had received HAV vaccine. The percentage of students who signify themselves at increased risk of acquiring viral hepatitis was 97.3%. Of the students, 28.1% had sustained a needle-stick injury and 5.4% had experienced conjunctival exposure to blood. CONCLUSIONS: Curriculum differences among nursing schools have a significant effect on nursing students' level of knowledge. For this reason, nursing schools should organize HBV immunisation programmes for their students to increase vaccination coverage.

Comparison of sequence analysis and INNO-LiPA HBV DR line probe assay in patients with chronic hepatitis B.

The aim of this study was to compare direct sequence analysis of partial HBV pol gene and Inno-LiPA HBV DR in serum samples of 120 chronic hepatitis B patients sent to the Clinical Microbiology Laboratory of Ege University Hospital because of lamivudine resistance. Sequence analysis was performed on ABI Prism 310 Genetic Analyzer. Comparison of Inno-LiPA and sequence results obtained by double-blind evaluation showed full agreement (both at rt180 and rt204) in 58.8% of samples. Visually rechecking of the electropherograms increased this rate to 68.3% Codon based rates are 81.7% and 75.8% at rt180 and rt204 respectively. LiPA detected variants in additional 12 (10%) samples, but missed one variant sample (both rt180 and rt204) and one sample was indeterminate due to poor probe binding. LiPA allows determination of mixed variants and seems to be more sensitive and simple for routine testing even though sequence analysis is still the gold standard for detecting new variants.

Carbapenem versus fosfomycin tromethanol in the treatment of extended-spectrum beta-lactamase-producing Escherichia coli-related complicated lower urinary tract infection.

The aim of this observational prospective study was to compare the effect of fosfomycin tromethanol (FT) and carbapenems (meropenem or imipenem cilastatin) in the treatment of extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli-related complicated lower urinary tract infection (CLUTI). Inclusion criteria were: patients who were aged >18 yr with dysuria or problems with frequency or urgency in passing urine; those with >20 leukocytes/mm³ in urine microscopy and culture-proven ESBL-producing carbapenem or FT-sensitive E. coli in the urine (>105 cfu/mm³); no leukocytosis or fever; and who were treated with ft (oral 3 g sachet x 1 every other night, three times) or carbapenems between march 2005 and January 2006 in our outpatient clinic and hospital. A total of 47 CLUTI attacks in 47 patients (27 FT group, 20 carbapenem group) were observed prospectively. Clinical and microbiological success in the carbapenem and ft groups was similar (19/20 vs 21/27 and 16/20 vs 16/27 p>0.05). Drug acquisition costs were significantly lower in the FT group (p<0.001). Although it is not a randomized controlled study, these data show that ft may be a suitable, effective and cheap alternative in the treatment of ESBL-producing E. coli-related CLUTI.
