Abstract
BACKGROUND & AIMS Until recently, pegylated interferon-alfa-2a (PEG-IFNa) therapy was the only treatment option for patients infected with hepatitis D virus (HDV). Treatment with PEG-IFNa with or without tenofovir disoproxil fumarate (TDF) for 96 weeks resulted in HDV RNA suppression in 44% of patients at the end of therapy but did not prevent short-term relapses within 24 weeks. The virological and clinical long-term effects after prolonged PEG-IFNa-based treatment of hepatitis D are unknown. METHODS In the HIDIT-II study patients (including 40% with liver cirrhosis) received 180 μg PEG-IFNa weekly plus 300 mg TDF once daily (n = 59) or 180 μg PEG-IFNa weekly plus placebo (n = 61) for 96 weeks. Patients were followed until week 356 (5 years after end of therapy). RESULTS Until the end of follow-up, 16 (13%) patients developed liver-related complications (PEG-IFNa + TDF, n = 5 vs PEG-IFNa + placebo, n = 11; p = .179). Achieving HDV suppression at week 96 was associated with decreased long-term risk for the development of hepatocellular carcinoma (p = .04) and hepatic decompensation (p = .009). Including complications irrespective of PEG-IFNa retreatment status, the number of patients developing serious complications was similar with (3/18) and without retreatment with PEG-IFNa (16/102, p > .999) but was associated with a higher chance of HDV-RNA suppression (p = .024, odds ratio 3.9 [1.3-12]). CONCLUSIONS Liver-related clinical events were infrequent and occurred less frequently in patients with virological responses to PEG-IFNa treatment. PEG-IFNa treatment should be recommended to HDV-infected patients until alternative therapies become available. Retreatment with PEG-IFNa should be considered for patients with inadequate response to the first course of treatment. CLINICAL TRIAL REGISTRATION NCT00932971.

Abstract
OBJECTIVES Results from two Phase 3 studies, through 2 years, in chronic hepatitis B infection (CHB) showed tenofovir alafenamide (TAF) had similar efficacy to tenofovir disoproxil fumarate (TDF) with superior renal and bone safety. Here, we report updated results through 5 years. METHODS Patients with HBeAg-negative or -positive CHB with or without compensated cirrhosis were randomized (2:1) to TAF 25 mg or TDF 300 mg once daily in double-blind (DB) fashion for up to 3 years, followed by open-label (OL) TAF up to 8 years. Efficacy (antiviral, biochemical, serologic), resistance (deep sequencing of polymerase/reverse transcriptase and phenotyping), and safety, including renal and bone parameters, were evaluated by pooled analyses. RESULTS Of 1298 randomized and treated patients, 866 receiving TAF (DB and OL) and 432 receiving TDF with rollover to OL TAF at year 2 (n = 180; TDF→TAF3y) or year 3 (n = 202; TDF→TAF2y) were included. Fifty (4%) TDF patients who discontinued during DB were excluded. At year 5, 85%, 83%, and 90% achieved HBV DNA < 29 IU/mL (missing = failure) in the TAF, TDF→TAF3y, and TDF→TAF2y groups, respectively; no patient developed TAF or TDF resistance. Median eGFR (by Cockcroft-Gault) declined < 2.5 mL/min, and mean declines of < 1% in hip and spine bone mineral density were seen at year 5 in the TAF group; patients in the TDF→TAF groups had improvements in these parameters at year 5 after switching to OL TAF. CONCLUSIONS Long-term TAF treatment resulted in high rates of viral suppression, no resistance, and favorable renal and bone safety.

Abstract
BACKGROUND & AIMS Infection with the hepatitis D virus (HDV) causes the most severe form of viral hepatitis with a high risk to develop clinical complications of liver disease. In addition, hepatitis delta has been shown to be associated with worse patient-reported outcomes. Until recently, only pegylated interferon alfa could be used to treat hepatitis delta. METHODS Here, we investigated quality of life (QOL) as assessed by the Short Form 36 Health Survey (SF-36) in patients undergoing antiviral therapy with pegylated interferon alfa (PEG-IFNa-2a)-based treatment in the HIDIT-II trial. HIDIT-II was a randomized prospective trial exploring PEG-IFNa-2a with tenofovir disoproxil (TDF) or placebo for 96 weeks in patients with compensated hepatitis delta. Surveys completed by 83 study participants before, during, and after treatments were available. RESULTS Overall, we observed a reduced QOL of HDV patients compared with a reference population, both in physical as well as mental scores. Interestingly, PEG-IFNa-2a treatment showed only minor impairment of the QOL during therapy. Moreover, HDV-RNA clearance was not associated with relevant changes in physical or social SF-36 scores, whereas an improvement of fibrosis during treatment was associated with increased QOL. Overall, slight improvements of the QOL scores were observed 24 weeks after the end of treatment as compared with baseline. TDF co-treatment had no influence on QOL. CONCLUSIONS Overall, our findings suggest that PEG-IFNa-2a was reasonably tolerated even over a period of 96 weeks by hepatitis D patients reporting SF-36 questionnaires. Of note, several patients may benefit from PEG-IFNa-2a-based therapies with off-treatment improvements in quality of life.

Abstract
OBJECTIVE The aim of this study was to analyze the temporal trends of HIV epidemiology in Turkey from 2011 to 2016. METHODS Thirty-four teams from 28 centers at 17 different cities participated in this retrospective study. Participating centers were asked to complete a structured form containing questions about epidemiologic, demographic and clinical characteristics of patients presented with new HIV diagnosis between 2011 and 2016. Demographic data from all centers (complete or partial) were included in the analyses. For the cascade of care analysis, 15 centers that provided full data from 2011 to 2016 were included. Overall and annual distributions of the data were calculated as percentages and the Chi square test was used to determine temporal changes. RESULTS A total of 2,953 patients between 2011 and 2016 were included. Overall male to female ratio was 5:1 with a significant increase in the number of male cases from 2011 to 2016 (p<0.001). The highest prevalence was among those aged 25-34 years followed by the 35-44 age bracket. The most common reason for HIV testing was illness (35%). While the frequency of sex among men who have sex with men increased from 16% to 30.6% (p<0.001) over the study period, heterosexual intercourse (53%) was found to be the most common transmission route. Overall, 29% of the cases presented with a CD4 count of >500 cells/mm3 while 46.7% presented with a CD4 T cell count of <350 cells/mm3. Among newly diagnosed cases, 79% were retained in care, and all such cases initiated ART with 73% achieving viral suppression after six months of antiretroviral therapy. CONCLUSION The epidemiologic profile of HIV infected individuals is changing rapidly in Turkey with an increasing trend in the number of newly diagnosed people disclosing themselves as MSM. New diagnoses were mostly at a young age. The late diagnosis was found to be a challenging issue. Despite the unavailability of data for the first 90, Turkey is close to the last two steps of 90-90-90 targets.

Abstract
BACKGROUND Hepatitis D is the most severe form of chronic viral hepatitis. Treatment guidelines recommend 1 year of peginterferon alfa, which is effective in 25-30% of patients only. Whether prolonged therapy with peginterferon alfa-2a for 96 weeks and combination therapy with tenofovir disoproxil fumarate (TDF) would increase hepatitis D virus (HDV) RNA suppression is unknown. We aimed to explore whether prolonged treatment of HDV with 96 weeks of peginterferon would increase HDV RNA response rates and reduces post-treatment relapses. METHODS We did two parallel, investigator-initiated, multicentre, double-blind randomised, controlled trials at 14 study sites in Germany, Greece, Romania, and Turkey. Patients with chronic HDV infection and compensated liver disease who were aged 18 years or older were eligible for inclusion. All patients were HBsAg positive for at least 7 months, anti-HDV positive for at least 3 months, and HDV-RNA positive at the local laboratory at the screening visit. Patients were ineligible if alanine aminotransferase levels were higher than ten times above the upper limit of normal and if platelet counts were lower than 90 000 per μL, or if they had received interferon therapy or treatment with a nucleoside and nucleotide analogue within the preceding 6 months. Patients were randomly assigned by blinded stratified block randomisation (1:1) to receive 180 μg of peginterferon alfa-2a weekly plus either TDF (300 mg once daily) or placebo for 96 weeks. The primary endpoint was the percentage of patients with undetectable HDV RNA at the end of treatment assessed by intention to treat. The trials are registered as NCT00932971 and NCT01088659. FINDINGS Between June 24, 2009, and Feb 28, 2011, we randomly assigned 59 HDV RNA-positive patients to receive peginterferon alfa-2a plus TDF and 61 to receive peginterferon alfa-2a plus placebo, including 48 (40%) patients with cirrhosis to the two treatment groups (23 in the peginterferon alfa-2a plus TDF group and 25 in the peginterferon alfa-2a plus placebo group). The primary endpoint was achieved in 28 (48%) of 59 patients in the peginterferon alfa-2a plus TDF group and in 20 (33%) of 61 patients in the peginterferon alfa-2a plus placebo group (odds ratio 1·84, 95% CI 0·86-3·91, p=0·12). We recorded 944 adverse events (459 in the peginterferon alfa-2a plus TDF group and 485 in the peginterferon alfa-2a plus placebo group). The most common adverse events were haematological, behavioural (eg, fatigue), musculoskeletal, influenza-like syndromes, and psychiatric complaints. INTERPRETATION Addition of TDF resulted in no significant improvement in HDV RNA response rates at the end of treatment. These findings highlight that alternative treatment options are needed for hepatitis D.

Abstract
Aim The aim of this study is to examine the role of the mean platelet volume (MPV), platelet distribution width (PDW), platelet/lymphocyte ratio (PLR), and platelet values for predicting mortality in patients with sepsis. Materials and Methods This is a retrospective study, involving patients 18 years and above who were diagnosed with sepsis. Blood samples were analyzed for platelets characteristics (counts, MPV, PDW, and PLR). The patients were separated into two groups namely the survivors and deceased. The two groups' MPV, PDW, PLR, and platelet counts which were considered to have an effect on mortality, were compared. Results Three hundred and thirty patients who were diagnosed with sepsis in our emergency department and complying with the study participation criteria were studied retrospectively. Comparison of the MPV, PDW, PLR, and platelet counts of the deceased and survivors showed that the MPV, PDW, and PLR were higher in the deceased while the platelet counts were higher in the survivors. Conclusion The low number of platelets in patients with sepsis at the moment of application and the high PDW and PLR values are valuable for predicting a high mortality.

Abstract
HIV-1 replication is rapid and highly error-prone. Transmission of a drug-resistant HIV-1 strain is possible and occurs within the HIV-1-infected population. In this study, we aimed to determine the prevalence of transmitted drug resistance mutations (TDRMs) in 1,306 newly diagnosed untreated HIV-1-infected patients from 21 cities across six regions of Turkey between 2010 and 2015. TDRMs were identified according to the criteria provided by the World Health Organization's 2009 list of surveillance drug resistance mutations. The HIV-1 TDRM prevalence was 10.1% (133/1,306) in Turkey. Primary drug resistance mutations (K65R, M184V) and thymidine analogue-associated mutations (TAMs) were evaluated together as nucleos(t)ide reverse transcriptase inhibitor (NRTI) mutations. NRTI TDRMs were found in 8.1% (107/1,306) of patients. However, TAMs were divided into three categories and M41L, L210W, and T215Y mutations were found for TAM1 in 97 (7.4%) patients, D67N, K70R, K219E/Q/N/R, T215F, and T215C/D/S mutations were detected for TAM2 in 52 (3.9%) patients, and M41L + K219N and M41L + T215C/D/S mutations were detected for the TAM1 + TAM2 profile in 22 (1.7%) patients, respectively. Nonnucleoside reverse transcriptase inhibitor-associated TDRMs were detected in 3.3% (44/1,306) of patients (L100I, K101E/P, K103N/S, V179F, Y188H/L/M, Y181I/C, and G190A/E/S) and TDRMs to protease inhibitors were detected in 2.3% (30/1,306) of patients (M46L, I50V, I54V, Q58E, L76V, V82A/C/L/T, N83D, I84V, and L90M). In conclusion, long-term and large-scale monitoring of regional levels of HIV-1 TDRMs informs treatment guidelines and provides feedback on the success of HIV-1 prevention and treatment efforts.

Abstract
Brucellosis is a zoonotic disease that primarily affects the reticuloendothelial system. But, the extent of liver damage in due course of the disease is unclear. This study included 325 brucellosis patients with significant hepatobiliary involvement identified with microbiological analyses from 30 centers between 2000 and 2013. The patients with ≥5 times of the upper limit of normal for aminotransferases, total bilirubin level ≥2 mg/dl or local liver lesions were enrolled. Clinical hepatitis was detected in 284 patients (87.3 %) and cholestasis was detected in 215 (66.1 %) patients. Fatigue (91 %), fever (86 %), sweating (83 %), arthralgia (79 %), and lack of appetite (79 %) were the major symptoms. Laboratory tests showed anemia in 169 (52 %), thrombocytopenia in 117 (36 %), leukopenia in 81 (25 %), pancytopenia in 42 (13 %), and leukocytosis in 20 (6 %) patients. The most commonly used antibiotic combinations were doxycycline plus an aminoglycoside (n = 73), doxycycline plus rifampicin (n = 71), doxycycline plus rifampicin and an aminoglycoside (n = 27). The duration of ALT normalization differed significantly in three treatment groups (p < 0.001). The use of doxycycline and an aminoglycoside in clinical hepatitis showed better results compared to doxycycline and rifampicin or rifampicin, aminoglycoside, doxycycline regimens (p < 0.05). However, the length of hospital stay did not differ significantly between these three combinations (p > 0.05). During the follow-up, treatment failure occurred in four patients (1 %) and relapse was seen in three patients (0.9 %). Mortality was not observed. Hepatobiliary involvement in brucellosis has a benign course with suitable antibiotics and the use of doxycycline and an aminoglycoside regimen seems a better strategy in select patients.

Abstract
OBJECTIVE To assess the epidemiology of healthcare-associated infections (HAIs) in a neurology unit in a university hospital. METHODS The study was carried out prospectively at Dicle University Hospital, Diyarbakir, Turkey (1050-bed) between 1st January 1999 and 31st December 2004. Active surveillance for HAIs was performed by the infection control team, using the criteria proposed by the Centers for Diseases Control and Prevention (CDC) and National Nosocomial Infections Surveillance System (NNIS) methodology. RESULTS During the 6-year follow up period, 219 HAIs episodes were detected in 203 patients out of 3323 in patients. The mean length of stay of patients with HAI was 28+/-5 days, while that of patients without infections was 11+/-1 days. Eighty-two patients died with HAIs, while 1330 died in the patients without infections. The overall incidence rates (HAI/100) and incidence densities (HAI/1000 days of stay) of HAIs were 6.6% and 4.4/1,000 patients-days. The most common HAIs by primary site were urinary tract infection (44.2%) and decubitus infection (30.4%). The most prevalent microorganisms were Escherichia coli (27%), Klebsiella species (14%), Pseudomonas aeruginosa (13%), Enterobacter species (12%), coagulase-negative Staphylococci (10%) and Staphylococcus aureus (7%). CONCLUSION The results may contribute to observe the magnitude and characteristics of HAIs and to plan and evaluate policies and guidelines of infection control in neurology units.

Abstract
OBJECTIVE To evaluate the efficacy of dexamethasone added to the treatment of adult patients with bacterial meningitis in our region. METHODS One hundred and forty-four patients were randomized prospectively and evaluated to determine the efficacy of dexamethasone treatment in adult patients with acute bacterial meningitis at Dicle University Hospital, Diyarbakir, Turkey between January 2000 and December 2004. While the first group received ceftriaxone 4 gr/day plus dexamethasone, the second group received ceftriaxone 4 gr/day only. Dexamethasone was given 10-15 minutes before the first 8 mg dose of antibiotic treatment. It was continued at 16 mg/day for 3 days. RESULTS The study included 144 patients with the diagnosis of acute bacterial meningitis. Cerebrospinal fluid (CSF) was analyzed at the time of admission, after 24-48 hours (Table 1), and at the end of treatment. Accordingly, CSF leukocyte level was found to be 1710+/-2140/mm3 in group 1 receiving dexamethasone treatment compared to 1950+/-2244/mm3 in group 2 (p=0.001). The consciousness in the group receiving dexamethasone improved significantly more rapidly than the control group (p=0.001). While mortality was 9.7% in the patient group receiving dexamethasone it was 16.7% in the control group, however, it was not significant (p=0.093). CONCLUSION The use of dexamethasone in adult patients is still under debate, and the administration of dexamethasone 10-15 minutes before antibiotherapy to unconscious patients in a poor state of health, is effective in the clinical improvement of the patient.

Abstract
OBJECTIVE To determine the relationship between nurse workload and multiresistant bacteria colonization or infection (MRB+) in a neurology intensive care unit (ICU). METHODS We studied the relationship between nurse workload and MRB+ development in patients who were hospitalized in Dicle University Neurology Department ICU, Turkey during a 6-month period from November 15, 2003 to April 15, 2004. The intensity of workload and procedures applied to the patients were scored with the Project de Recherche en Nursing (PRN) and the Omega scores. RESULTS Of 138 patients followed, 71 (51.4%) were female and 67 (48.6%) were male. The mean age of females was 65.6+/-6.7 years, and of males was 62.2+/-15.8 years. The mean time of hospitalization in the ICU was 13+/-7.6 days. In 26 (18.8%) cultures taken from patients, multiresistant bacteria (MRB) were demonstrated. The development of MRB+ infection was correlated with length of stay (LOS), Omega 2, Omega 3, Total Omega, daily PRN, and total PRN (p<0.05). There was no correlation between development of MRB+ infection with gender, age, APACHE-II and Omega 1 scores (p>0.05). In the PRN system, when the workload of nurses was compared, it was seen that in the MRB colonized patient group, the workload of nurses was meaningfully higher than the MRB patient (-) group (p<0.001). CONCLUSION As a result, the risk of MRB+ development in the ICU is directly proportional to understaffing, increased nurse workload, LOS, and procedures applied to patients. In management of nosocomial infection, it is crucial to increase the number of nurses in the ICU, and thus, decrease the workload.

Abstract
OBJECTIVE To obtain regional epidemiological data on hepatitis delta virus (HDV, a defective virus) infections, the incidence of anti-HDV positivity and the associated risk factors in asymptomatic hepatitis B virus surface antigen (HBsAg) carriers and in patients with chronic active hepatitis B. METHODS The study took place at Dicle University Hospital (Diyarbakir, Southeast of Turkey) between January 2002 and July 2004. Anti-HDV screening was performed in asymptomatic hepatitis B carriers (N=889) and in patients with chronic active hepatitis B infection (N=120). We explored the association between anti-HDV positivity and asymptomatic hepatitis B carrier status, presence of active hepatitis B, age, gender, the durations of HBsAg positivity and hepatitis B e antigen (HBeAg) positivity. RESULTS In 6% of asymptomatic hepatitis B carriers (53/889) and in 27.5% of patients with chronic active hepatitis B (33/120) anti-HDV was positive. The incidence of anti-HDV positivity was significantly higher in patients with chronic active hepatitis B compared with asymptomatic carriers (p<0.001). A significant association between the duration of HBsAg carrier status (3.2 +/- 1.4 years) and anti-HDV positivity was also found (p<0.001). Age, gender, and HBeAg positivity were not significantly associated with anti-HDV positivity (p>0.05). CONCLUSION Anti-HDV positivity was significantly more common in patients with chronic hepatitis B compared with asymptomatic hepatitis B virus (HBV) carriers in a region with a high prevalence of HBV infection. We found a significant relationship between the duration of HBsAg carrier status and anti-HDV positively, however, age, gender, and presence of HBeAg were not significantly associated with the development of anti-HDV positivity.

Abstract
Malignant otitis externa (MOE) is a severe infection of external auditory canal and skull base. A 17-year-old diabetic girl was admitted with diabetic ketoacidosis. Cellulitis of her right ear occurred on the second day of hospitalization and a black necrotic scar in the same region appeared on the next day. The lesion rapidly invaded to right side of neck and surrounding tissue of the patient. Therefore, antimycotic therapy was started. Unfortunately the patient died on seventh day of hospitalization because of probably extensive fungal invasion. Physicians should suspect MOE connected to mucormycosis especially in patients with cutaneous lesions of ear unresponsive to antibiotic therapy.

Abstract
We conducted a case-control study to assess risk factors for typhoid fever in Diyarbakir, Turkey, a region where transmission of Salmonella typhi is endemic. We prospectively identified febrile patients from Diyarbakir and the surrounding area who were admitted to hospital. Cases were defined as patients who had S. typhi isolated from at least one blood culture. Sixty-four cases with blood culture-confirmed S. typhi were identified between May 2001 and May 2003. In total, 128 age- and sex-matched controls selected from neighbourhoods as cases were enrolled. We hypothesized that consumption of raw vegetables contaminated with sewage would be associated with an increased risk of typhoid fever. Conditional logistic regression modelling revealed that living in a crowded household (OR 3.31, 95% CI 1.58-6.92, P=0.002), eating cig kofte (a traditional raw food) (OR 5.29, 95% CI 2.20-12.69, P=0.000) and lettuce salad (OR 3.55, 95% CI 1.52-8.28, P=0.003) in the 15 days prior to symptoms onset was independently associated with typhoid fever. We conclude that living in a crowded household and consumption of raw vegetables outside the home increase the risk of typhoid fever in this region.
