ABSTRACT
Predicting the need of hospitalization and intensive care in COVID-19 patients has been challenging with current diagnostic tests since the beginning of the pandemic. We aimed to test cell free DNA (cfDNA) as a novel biomarker for COVID-19 disease severity and mortality. cfDNA concentration was quantified by RT-PCR based test. One hundred and sixty-eight patients(85 outpatients, 61 inpatients,22 ICU) included the study. Mean initial plasma cfDNA levels were significantly different (p < 0.01) in outpatients (1.190,66 ng/ml), inpatients (8.258,10 ng/ml) and ICU patients (84.806,87 ng/ml). ROC analysis showed with 95 % specificity that patients with initial cfDNA concentrations ≥6.389 ng/ml need to be hospitalized and those ≥26.104 ng/ml require ICU referral. cfDNA concentration was correlated with neutrophil/lymphocyte ratio, lymphocyte level, CRP, AST, LDH, CK, fibrinogen, ferritin and D-dimer. Plasma cfDNA levels on admission, well correlating with disease severity and mortality in COVID-19 that found as a useful biomarker.

AIMS: The COVID-19 pandemic has substantially changed lives and presented several barriers to health services. HIV care continuum needs a high rate of diagnosis, effective treatment, and sustained suppression of viral replication. The COVID-19 pandemic has affected these three steps of HIV care. This study investigated the characteristics of newly diagnosed patients living with HIV/AIDS (PLWH) during the COVID pandemic and compared them with those before the pandemic. METHODS: All newly diagnosed patients in three HIV healthcare centers, in Istanbul, Turkey, were included in the study. The pandemic period included April 1, 2020, to April 1, 2021, and the prepandemic period included March 1, 2019, to March 1, 2020. RESULTS: 756 patients were diagnosed with HIV/AIDS. In the pandemic period, this figure was 58% less: 315. Patients in the pre-pandemic and pandemic period had comparable age and gender distributions. PLWH diagnosed in the pandemic period had higher rates of low CD4 cells: low CD4 (<350 cells /mm3) was measured in 243 (36.4%) patients in the pre-pandemic period, while it was done in 126 (47.9%) in the pandemic period (p<0.01). Also, the distribution of CD4 cells was significantly different between periods: In the pandemic period, CD4 cell distribution significantly skewed to lower CD4 categories. Symptomatic patient rates and AIDS-defining disorder rates among symptomatic patients were comparable. Viral loads were not significantly different in the two periods. CONCLUSION: A low number of newly diagnosed PLWH can be explained by less HIV testing, less admission to health care, or an actual decrease of HIV prevalence during the pandemic. Sexual behaviors may have changed during the COVID-19 pandemic, leading to HIV transmission restriction. Lower CD4 counts among the newly diagnosed PLWH suggest that admittance to health care is late and a significant portion of PLWH remain undiagnosed.

PURPOSE: The goals of this study were to report our clinical experience in a single center at a high-volume tertiary university hospital in Istanbul and to introduce a diagnostic algorithm based on a 5-year follow-up of 152 women with biopsy-proven idiopathic granulomatous mastitis (IGM). IGM is an uncommon, non-malignant, chronic inflammatory disease of the mammary gland with an unknown etiology. The symptoms, clinical presentation, and radiologic findings of IGM may resemble carcinomas. To our knowledge, this study comprises the largest series of IGM, especially with a 5-year follow-up, yet reported in the English literature. METHODS: The present study reported our single-center clinical experience at a tertiary university hospital in Istanbul, Turkey, and introduced a diagnostic algorithm using our treatment protocol based on a 5-year follow-up of 152 women with biopsy-proven IGM. Our database of 10 years' experience containing over 700 patients with IGM was evaluated. However, to assess recurrence and resistance to treatment, only the 152 patients with a long follow-up period of 5 years were included in the study group. The analysis included 152 women with biopsy-proven IGM who were treated between January 2009 and March 2014. The clinical data of the presentation, histopathology, and treatment modalities were analyzed by reviewing the medical records. RESULTS: Of the 152 patients diagnosed with granulomatous mastitis, 32 (21%) recovered by expectant management, while 14 (9%) responded to antibiotics, 65 (43%) received corticosteroids, 20 (13%) had antituberculosis medication, 16 (11%) underwent excision, and 5 (3%) responded to non-steroidal anti-inflammatory drugs. Fifty-one patients (33%) had recurrence; of these, 30 achieved a cure with second-line treatment, 16 underwent excision, and 5 achieved a cure with observation. CONCLUSION: IGM is a rare benign breast disorder, and clinicians need a high index of suspicion to diagnose it, as IGM can be mistaken for breast cancer. Unlike periductal mastitis, IGM does not evolve secondary to nicotine addiction and is typically seen in women of childbearing age with a recent history of pregnancy and lactation. The diagnosis can be challenging, and an evaluation with a multidisciplinary team is necessary. There is no consensus concerning the definitive treatment approach. We suggested a diagnostic algorithm in the present study, using our treatment protocol based on the 5 years' follow-up of 152 women.

HIV/AIDS-related stigma remains a crucial public health problem in the world. Unfortunately, health provider staffs such as nurses and physicians are the major source of stigmatization and discrimination against peoples living with HIV (PLHIVs) including in Turkey. The aim of this study was to assess HIV-related stigma towards to PLHIV by nurses and physicians and to examine related factors. Descriptive Assessment Form and the HIV-Related Stigma Scale used for data collection. The study consisted of 405 health workers including 251 nurses and 154 physicians. Over 86% of physicians and 69.3% of nurses had no specific education about HIV. More than 11% of the nurses and 8.4% of the physicians expressed that HIV can be transmitted with handshaking or breathing in a shared environment. Fear-driven stigma was significantly different by age, education, occupation, and work experience. Over 14% of the discrimination (Adjusted R2 = .14 F(15-389) = 4.46 P = .000), and 10% of the disclosure were explained by the variables (Adjusted R2 = .10 F(15-389) = 4.29 P = .000). The discrimination dimension had a strong positive relationship with the knowledge of HIV transmission modes. In our view, if physicians and nurses receive adequate and comprehensive training on HIV including stigma, the formations of stigma may be prevented and may not develop.

PURPOSE: We aimed to determine significant risk factors for biofilm production and to investigate the association between antimicrobial resistance profile and biofilm formation in the bacterial isolates obtained from patients with diabetic foot infection (DFI). METHODS: Demographic, clinical, laboratory and outcome data of 165 patients, prospectively recorded and followed between January 2008 and December 2015 by a multidisciplinary committee, were analysed. Standard microbiological methods were adopted. Risk factors associated with biofilm were determined by univariate and multivariate analyses. RESULTS: The overall rate of biofilm production among 339 wound isolates was 34%. The biofilm production rate was significantly higher in Gram-negative micro-organisms (39%) in comparison with Gram positives (21%) (P = .01). A. baumannii presented the highest biofilm production (62%), followed by P. aeruginosa (52%) and Klebsiella spp. (40%). On univariate analysis, significant factors associated with biofilm were antibiotic use within last 3 months (OR:2.94, CI: 1.5-5.75, P = .002), recurrent DFI within last 6 months (OR:2.35, CI: 1.23-4.53, P = .01), hospitalisation within last 3 months due to ipsilateral recurrent DFI (OR:2.44, CI: 1.06-5.58, P = .03), presence of amputation history (OR: 2.20, CI: 1.14-4.24, P = .01), multidrug-resistant (MDR) micro-organism (OR: 7.76, CI: 4.53-13.35, P<.001) and extensively drug-resistant (XDR) micro-organism (OR:11.33, CI:4.97-26.55, P<.001). Multivariate regression analysis revealed two variables to be significant factors associated with biofilm: MDR micro-organism (OR: 3.63, CI: 1.58-8.33, P = .002) and XDR micro-organism (OR:4.06, CI: 1.25-13.1, P = .01). CONCLUSIONS: Multi/extensive drug resistance and previous recurrent DFIs were significantly associated with biofilm formation in patients with diabetic foot.

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.

OBJECTIVES: Idiopathic granulomatous mastitis (IGM) is a benign rare inflammatory pseudotumor. Bilateral involvement of IGM has been reported in a few cases. To our knowledge, this study is the largest series of bilateral cases to date. The goals of this study were to present clinical features of bilateral IGM and to evaluate the results of treatments. MATERIALS AND METHODS: We performed a retrospective review of the idiopathic granulomatous mastitis database from 2010 to 2013. Ten female patients who met required histologic and clinical criteria of IGM in both breasts were included in study. Demographic data, clinical findings, medication history, and radiologic findings are presented. RESULTS: The mean age at onset of the disease was 38.4 ± 8.3 years (range: 29-52 years). Nine patients had no recurrence during a mean follow-up period of 21 months (range: 11-26 months). Additionally, the median time to second breast involvement was 15.6 months. CONCLUSION: Bilateral IGMs have a higher rate of more relapse and greater resistance to medical therapies than do unilateral IGMs. Surgical management should be avoided unless all medical treatment options have been exhausted. Nevertheless, expectant management seems a rational option for the treatment of bilateral IGM.

BACKGROUND CONTEXT: No direct comparison between brucellar spondylodiscitis (BSD) and tuberculous spondylodiscitis (TSD) exists in the literature. PURPOSE: This study aimed to compare directly the clinical features, laboratory and radiological aspects, treatment, and outcome data of patients diagnosed as BSD and TSD. STUDY DESIGN: A retrospective, multinational, and multicenter study was used. PATIENT SAMPLE: A total of 641 (TSD, 314 and BSD, 327) spondylodiscitis patients from 35 different centers in four countries (Turkey, Egypt, Albania, and Greece) were included. OUTCOME MEASURES: The pre- and peri- or post-treatment spinal deformity and neurologic deficit parameters, and mortality were carried out. METHODS: Brucellar spondylodiscitis and TSD groups were compared for demographics, clinical, laboratory, radiological, surgical interventions, treatment, and outcome data. The Student t test and Mann-Whitney U test were used for group comparisons. Significance was analyzed as two sided and inferred at 0.05 levels. RESULTS: The median baseline laboratory parameters including white blood cell count, C-reactive protein, and erythrocyte sedimentation rate were higher in TSD than BSD (p<.0001). Prevertebral, paravertebral, epidural, and psoas abscess formations along with loss of vertebral corpus height and calcification were significantly more frequent in TSD compared with BSD (p<.01). Surgical interventions and percutaneous sampling or abscess drainage were applied more frequently in TSD (p<.0001). Spinal complications including gibbus deformity, kyphosis, and scoliosis, and the number of spinal neurologic deficits, including loss of sensation, motor weakness, and paralysis were significantly higher in the TSD group (p<.05). Mortality rate was 2.22% (7 patients) in TSD, and it was 0.61% (2 patients) in the BSD group (p=.1). CONCLUSIONS: The results of this study show that TSD is a more suppurative disease with abscess formation requiring surgical intervention and characterized with spinal complications. We propose that using a constellation of constitutional symptoms (fever, back pain, and weight loss), pulmonary involvement, high inflammatory markers, and radiological findings will help to differentiate between TSD and BSD at an early stage before microbiological results are available.

PURPOSE: Idiopathic granulomatous mastitis (IGM) is a rare benign inflammatory disease of the breast. It can mimic breast carcinoma clinically and radiologically, and usually affects females of childbearing age. There is no commonly accepted optimal treatment for IGM. In this study, we present the clinical and histopathological features and outcomes of the therapeutic management of IGM, as well as the clinical course of the disease when patients were treated with oral corticosteroids. METHODS: This retrospective study included 49 of 87 patients who met the required histological criteria for IGM who were followed up between January 2009 and December 2011. All patients had a disease-free follow-up period of at least 6 months. The data regarding the clinical features at presentation, laboratory values and the treatment modalities were obtained from the medical records of the patients. RESULTS: The mean age of the patients was 34.3 ± 4.37 years. Forty patients were treated with prednisolone, five were started on antituberculosis treatment, two received non-steroidal anti-inflammatory drugs, one received antibiotics and one underwent wide excision. All patients who received steroids responded well to the therapy. CONCLUSION: Systemic therapy with corticosteroids is an effective and appropriate treatment option for IGM. It can provide complete disease resolution and prevent recurrence in the long term. A multidisciplinary approach including specialists in the fields of both general surgery and infectious diseases is essential for the diagnosis, treatment and follow-up of IGM.

Candidal infections occur commonly in renal transplant recipients especially in genitourinary system. Although the epidemiology of candiduria has not been well characterized in renal transplant population, it is the most common cause of fungal infections. However, candidal psoas abscess is very rare in the literature. We report a 42-year-old male renal transplant recipient with prolonged pyuria and candiduria followed by candidal psoas abscess formation. The treatment consisted of prolonged antifungal therapy along with percutaneous drainage. However, eventually, a surgical drainage had to be performed for the successful eradication.

Human immunodeficiency virus (HIV) characterized by a high genetic variability includes two genotypes namely HIV-1 and HIV-2. A major proportion of the infections worldwide is caused by HIV-1 which includes four groups (M, N, O and P). Group M being responsible for the HIV pandemic is further divided into nine genetically distinct subtypes (A, B, C, D, F, G, H, J, and K). Additionally, more than 49 circulating recombinant forms (CRFs) have been recognized up to now. The aim of this study was to determine the subtype characterization and prevalence of HIV strains isolated from patients inhabiting in Istanbul, Turkey. The study was carried out between June 2009 and June 2012 and a total of 72 patients [58 male, 14 female; age range: 20-57 (median: 37) years; CD4+ T cell count range: 3-813 (median: 243)/mm3; HIV-RNA load range: 1.5+E3-1.0+E7 (median: 5.8+E5) IU/ml] were included in the study. Fortysix of the patients (64%) have acquired the infection via heterosexual and 23 (32%) via homosexual contact. Of the patients 57 were newly diagnosed and antiretroviral (ARV) therapy-naïve patients, while 15 were under different ARV therapies. For HIV-1 subtyping the most widely known algorithm (HIVdb-Stanford University Genotypic Resistance Interpretation Algoritm) was used. The population-based sequencing of the reverse transcripta ise region (pol) of HIV-1 indicated that CRFs (36/72; 50%) were the most commonly identified strains, followed by subtype B (31/72; 43%) among Turkish patients. Sub-subtypes A1 (3/72; 4.2%) and F1 (2/72; 2.8%) were also detected as low prevalent. The recombinant forms of HIV-1 circulated in Istanbul, Turkey were found as follows, respectively; CRF02_AG [%25 (18/72), West Africa, Central Africa and Middle East/North Africa origin], CRF12_BF [%12.5 (9/72), South America origin], CRF03_AB [%9.7 (7/72), Eastern Europe and Central Asia origin] and CRF01_AE [%2.8 (2/72), South-East Asia, East Asia and Central Africa origin]. Since molecular epidemiologic studies are important tools for tracking the transmission and spread patterns, and for the control of the HIV infections, HIV molecular studies should be expanded in HIV-1 infected Turkish patients. Furthermore, the determined subtypes and CRFs of HIV-1 in Turkey may be expected to contribute to global HIV surveillance systems.

INTRODUCTION: This study aimed to determine the incidence and risk factors of infections among patients admitted to intensive care units (ICUs) in tertiary care hospitals in Turkey. METHODS: Adult patients who were admitted to the ICUs of five tertiary care hospitals for over 48 hours between June and December 2007 were monitored daily. Potential risk factors such as age, gender, comorbidities, diagnosis at admission, severity of disease (Acute Physiology and Chronic Health Evaluation II scores), exposure to antibiotics, history of invasive procedures and significant medical interventions were evaluated. A multivariate analysis of these risk factors was carried out using Cox regression. RESULTS: A total of 313 patients with a median ICU stay of 12 days were selected for the study. 236 infectious episodes (33.8/1,000 ICU-days) were diagnosed among 134 patients (42.8/100 patients) in this group. Multivariate analysis revealed that exposure to a cephalosporin antibiotic (hazard ratio [95% confidence interval] 1.55 [1.10-2.19]) was an independent risk factor, whereas having a tracheostomy cannula (0.53 [0.36-0.81]) or nasogastric tube (0.48 [0.33-0.70]) was protective. Patients admitted to the ICUs from surgical wards were significantly more exposed to cephalosporins. CONCLUSION: ICU-associated infections, which are quite high in Turkey, are largely due to inadequate infrastructure and facilities and understaffing. Abuse of antibiotics, particularly in patients who have undergone surgery, and prolonged ICU stays are significant risk factors for such infections.

The Meropenem Yearly Susceptibility Test Information Collection (MYSTIC) Program is a global study that provides antimicrobial susceptibility data in centers prescribing meropenem. The activity of meropenem and 7 broad-spectrum antimicrobials have been examined against 5208 bacterial isolates from 9 Turkish centers between 2000 and 2003. Cumulative susceptibility rates against all species of Enterobacteriaceae combined were ranked as follows: meropenem (99.3%), imipenem (97.6%), cefepime (80.0%), piperacillin-tazobactam (73.6%), ceftazidime (70.3%), ciprofloxacin (70.1%), cefotaxime (66.9%), and tobramycin (67.2%). The production of extended-spectrum beta-lactamases (ESBLs) was detected in 48.7% of Klebsiella pneumoniae and in 19.5% of Escherichia coli isolates. Of ESBL producing K. pneumoniae isolates, 75.7% were resistant to tobramycin, 40.3% to ciprofloxacin, and 48.3% to piperacillin-tazobactam. Only piperacillin/tazobactam and carbapenems were active against more than 50% of Pseudomonas aeruginosa at the National Committee for Clinical Laboratory Standards-susceptible breakpoint, and the carbapenems were the most active compounds against Acinetobacter spp. These data confirm the continued potency of meropenem against Enterobacteriaceae in units where it is actively being prescribed.
