Complications and Long-Term Outcomes in Adult Patients Undergoing Living Donor Liver Transplantation Because of Fulminant Hepatitis.

BACKGROUND: The present study investigates the complications that may occur during long-term follow-up in patients aged 18 years and older undergoing living donor liver transplantation (LDLT) in our clinic because of fulminant hepatitis. METHODS: The study included patients aged 18 years and older with a minimum survival of 6 months who underwent an LDLT between June 2000 and June 2017. The demographic data of the patients were evaluated in terms of late-term complications. RESULTS: Of the 240 patients who met the study criteria, 8 (3.3%) underwent LDLT for fulminant hepatitis. The indication for transplantation in patients with fulminant hepatitis was cryptogenic liver hepatitis in 4 patients, acute hepatitis B infection in 2 patients, hemochromatosis in 1 patient, and toxic hepatitis in 1 patient. Of the 240 patients, 65 (27%) undergoing LDLT underwent a liver biopsy for suspected rejection because of an elevation in liver function test results during follow-up. Histopathologic scoring was carried out according to the Banff scoring system. A diagnosis of late acute rejection was made in only 1 of the 8 patients (12.5%) who underwent LDLT for fulminant hepatitis. CONCLUSION: Patients with fulminant hepatitis must be prepared for an LDLT, if available, while waiting for a cadaveric donor. The results of the present study suggest that LDLTs in patients with fulminant hepatitis are safe, and the outcomes are acceptable in terms of survival and complications.

Pediatric hospital healthcare workers and pertussis; a seroprevalence study.

BACKGROUND: This study aimed to assess pertussis seroprevalence among healthcare workers (HCWs) of a university children`s hospital and to determine their opinions on whether to get the pertussis vaccine booster dose in adulthood. METHODS: This cross-sectional study was carried out between January 2018 and March 2019. Data recording forms were filled by the face to face interview method. Anti-pertussis toxin IgG (Anti-PT IgG) antibody levels were determined quantitatively from the serum samples using a commercial enzyme-linked immunosorbent assay (ELISA) kit. Anti-PT IgG results were interpreted according to World Health Organization (WHO) recommendations. RESULTS: Of the 169 HCWs included in the study, 67 (39.6%) were seronegative and susceptible to pertussis. Seropositivity was significantly higher among HCWs who worked 40-80 hours per week. Thirty-six (21.3%) HCWs had high anti-PT IgG levels, indicating recent infection in the past few years. High-level positivity was significantly more common among HCWs using macrolide antibiotics due to prolonged cough. Anti-PT IgG levels of three (1.8%) were compatible with acute infection and they were not followed up with suspicion of whooping cough and were not isolated. While 125 (74.0%) of the participants said they could get the pertussis vaccine booster dose, only three (1.8%) had done so. CONCLUSIONS: The fact that 39.6% of HCWs were seronegative, emphasized the need for the pertussis booster dose. More than 20% of HCWs have had the acute infection without pertussis diagnosis in the past few years. Adult vaccination awareness in HCWs has not yet created a change in behavior. The high rate of seropositivity in macrolide users also shows that we cannot prevent its spread despite treatment. These findings highlight the fact that pertussis can occur in adult age groups and that eradication cannot be achieved without effective adult immunization and surveillance.

Epidemiology and susceptibility of pathogens from SMART 2011-12 Turkey: evaluation of hospital-acquired versus community-acquired urinary tract infections and ICU- versus non-ICU-associated intra-abdominal infections.

Objectives: To describe the epidemiology and susceptibility of pathogens (including ESBL producers) from hospital-acquired (HA) versus community-acquired (CA) urinary tract infections (UTIs) and ICU- versus non-ICU-associated intra-abdominal infections (IAIs) in Turkey as a part of the SMART study. Methods: : For this report, Gram-negative pathogens (363 from UTIs and 458 from IAIs) were collected in 2011 and 2012 at six hospitals in Turkey. HA versus CA UTIs and ICU- versus non-ICU-associated IAIs were compared for the species isolated, percentage of ESBL-positive isolates by species and susceptibility for overall and individual Gram-negative species. Results: : Escherichia coli was the most common pathogen identified in HA (40.2%) and CA (73.9%) UTIs and ICU-associated (25.8%) and non-ICU-associated (43.3%) IAIs. The rate of ESBL-positive E. coli was significantly higher in HA than in CA UTIs (50.5% versus 38.2%, P < 0.001) and in non-ICU-associated than in ICU-associated IAIs (52.5% versus 29.2%, P = 0.029). Of the drugs studied, only amikacin was active against ≥90% of pathogens in UTIs, while ertapenem, imipenem and amikacin were active against ≥90% of E. coli ; and imipenem, amikacin and cefoxitin were active against ≥90% of Klebsiella pneumoniae in IAIs. Conclusions: Our findings demonstrated that E. coli continues to be the principal pathogen of UTIs and IAIs in Turkey. Along with a high rate of ESBL-positive isolates, high antimicrobial resistance among Gram-negative bacilli from either UTIs or IAIs was noted particularly in the case of HA UTIs and ICU-associated IAIs, with a higher likelihood of carbapenem- or amikacin-based therapy to provide the broadest activity against bacterial pathogens.

[The rate of inducible clindamycin resistance and susceptibilities to other antimicrobial agents in staphylococci]. / Stafilokokoklarda indüklenebilir klindamisin direnci ve diger antibiyotiklere duyarlilik oranlari.

Staphylococci are one of the most common pathogens isolated from nosocomial and community acquired infections. Antibiotics used by oral route such as erythromycin, clindamycin, trimethoprim-sulphamethoxazole (TMP-SMX) and quinolones are of value especially in the treatment of community acquired infections and resistance to those antibiotics may lead to therapeutic failure. Therefore in this study, susceptibility of staphylococci to TMP-SMX, rifampin, tetracycline, gentamicin, ciprofloxacin and vancomycin and the presence of inducible clindamycin resistance were investigated in two distinct university hospitals in Turkey. A total of 286 staphylococcus strains [184 Staphylococcus aureus, 102 coagulase negative staphylococci (CoNS)] were studied. Of the 90 hospital-acquired S. aureus, 44.6% were methicillin-resistant while all of the community acquired strains were methicillin-susceptible. All of the CoNS strains were isolated from nosocomial infections and 71.6% of them were resistant to methicillin. Inducible clindamycin resistance rate of CoNS strains (34.3%) was higher than that of S. aureus strains (7.1%) and the difference was statistically significant (p= 0.00001). Positive D-test among CoNS were significantly higher in S. hominis strains (p= 0.00001). Susceptibilities of S. aureus strains to tetracycline, rifampin, ciprofloxacin, gentamicin and TMP-SMX were 56%, 59%, 56%, 56% and 99%, respectively. Susceptibilities of CoNS strains to tetracycline, rifampin, ciprofloxacin, gentamicin and TMP-SMX were 73%, 72%, 39%, 40% and 46%, respectively. None of these strains were vancomycin resistant. Differences between tetracycline, rifampin, ciprofloxacin and gentamicin resistance rates among D-test positive and negative S. aureus strains were found statistically significant. Although among CoNS isolates, no statistically significant difference was found between the resistance rates, D-test positive strains were determined to be more resistant. Differences between tetracycline, rifampin, ciprofloxacin and gentamicin resistance rates among D-test positive S. aureus and CoNS strains were found statistically significant. It can be concluded that inducible clindamycin resistance should be tested for staphylococci during routine antibiotic susceptibility testing. According to the presented data, clindamycin still can be used empirically in methicillin-susceptible S. aureus infections in our region, however, the routine use of rapid, easy, reproducible and economic D-test for the determination of inducible clindamycin resistance in erythromycin resistant strains should be considered in clinical microbiology laboratories. Inducible clindamycin resistance must be anticipated carefully while considering therapeutic options especially for CoNS infections.

Infectious disease consultations and antibiotic usage in a Turkish university hospital.

OBJECTIVES: The aim of this study was to investigate the various features of infectious disease (ID) consultations and the usage of antibiotics in a Turkish university hospital. METHODS: A total of 395 consultation requests were recorded during a three-year period. RESULTS: The departments most frequently requesting the consultation services of the ID department were Orthopedics (29.6%), Neurology (18.5%), Cardiology (11.8%) and Internal Medicine (10.4%). The main reasons were for diagnosis of unexplained fever (42.3%) and for antibiotic modification according to culture results (18%). Diagnoses made by the ID consultant were pneumonia (16.7%), urinary tract infections (9.3%), bone and joint prosthesis infections (9.1%) and in 15.7% of the investigated patients, no infectious focus was determined. It was recognized that the use of antibiotics had already been initiated in the great majority of patients (67.1%) before the consultation request. While the current therapy was changed in 57.4% of these patients, antibiotics were not necessary for 9.8%. CONCLUSIONS: Since the most common diagnoses were respiratory and urinary tract or bone and joint prosthesis infections, the ID specialists should have detailed knowledge of these problems. Usage of antibiotics without ID consultation was prevalent, therefore a continuous educational program is a necessity for healthcare workers in the hospital.
