Abstract
The primary strategy in the fight against cancer is to screen compounds that may be effective on different types of cancer. Compounds from plants seem to be a good source. The present study investigated the inhibitory effects of some flavonoids on the 6-phosphogluconate dehydrogenase (6-PGD) enzyme. We determined that quercetin, myricetin, fisetin, morin, apigenin, and baicalein exhibited powerful inhibition effects with IC50 values between 4.08 and 21.26 µM, while luteolin, kaempferol, apiin, galangin, and baicalin showed moderate effects with IC50 values between 54.15 and 138.91 µM. Quercetin competitively inhibited the binding of NADP and 6-phosphogluconate to the 6-PGD enzyme with Ki values of 0.527 ± 0.251 and 0.374 ± 0.138 µM, respectively. We calculated Ki values using the Cheng-Prusoff equation as between 0.44 and 14.88 µM. The possible interaction details of polyphenols with the active site of 6-PGD were analyzed with docking software. In silico and in vitro studies indicated that the -OH groups on the A and C ring of flavonoids bind to the enzyme's active site via hydrogen bonding, while the -OH groups on the C ring contributed significantly to the increase in the inhibitory potentials of the molecules. Molecular dynamic simulations tested the stability of the 6-PGD-quercetin complex during 100 ns. These phytochemicals were suitable for drug use when optimized with absorption, distribution, metabolism, excretion, and toxicity (ADMET) criteria. The effects of the studied compounds on cancer cell lines of potential targets were demonstrated by network analysis. In conclusion, this study suggests that flavonoids found to be potent inhibitors could serve as leading candidates to treat many cancers via 6-PGD inhibition.

Abstract
Blastocystis sp. is a zoonotic parasite that is common in humans and animals and settles in the large intestine. The parasite can cause various gastrointestinal system complaints such as indigestion, diarrhea, abdominal pain, bloating, nausea and vomiting. The aim of this study is to determine the distribution of Blastocystis in patients diagnosed with ulcerative colitis, Crohn's and diarrhea from the gastroenterology outpatient clinic and to compare the diagnostic value of the most preferred methods. A total of 100 patients, 47 men and 53 women, were included in the study. Of the cases, 61 had diarrhea, 35 had ulcerative colitis (UC) and four had Crohn's disease. Stool samples of the patients were analyzed by as direct microscopic examination (DM), culture and real-time polymerase chain reaction (qPCR). A total of 42% positivity was detected, 29% positivity in DM and trichrome staining, 28% in culture and 41% in qPCR. 40.4% (20/47) of men and 37.7% (22/53) of women were found to be infected. Blastocystis sp. was found in 75% of Crohn's, 42.6% of diarrheal and 37.1% of UC patients. Diarrhea cases are more common with UC and there is a close relationship between Crohn's and Blastocystis positivity. While DM and trichrome staining showed a sensitivity of 69%, PCR test was found to be the most sensitive diagnostic method with approximately 98%. Diarrhea and UC are often seen together. A close relationship was detected between Crohn's disease and Blastocystis. High prevalence of Blastocystis in cases with clinical symptoms reveals the importance of the parasite. There is a need for studies on the pathogenicity of Blastocystis sp. in various gastrointestinal cases, and it is thought that molecular techniques should be used since PCR is seen to be a much more sensitive.

Abstract
BACKGROUND We aimed to investigate the effect of hemoglobin/prognostic nutritional index and hemoglobin/red blood cell distribution, which are indicators of inflammation and nutrition, on prognosis and survival in patients with rectal cancer. METHODS The retrospective study reviewed medical records of 138 patients with rectal cancer who were followed up between 2010 and 2021. The effects of hemoglobin/red blood cell distribution, hemoglobin/prognostic nutritional index, tumor stage, and lymph node status on survival and prognosis were evaluated using univariate and multivariate analyses. Overall survival and disease-free survival were calculated for both groups. RESULTS Survival and prognosis were found to be significantly better in nonanemic patients with the hemoglobin/prognostic nutritional index higher than the cut-off value than in anemic patients with a normal or lower hemoglobin/prognostic nutritional index. Similarly, survival and prognosis were found to be significantly better in nonanemic patients with a hemoglobin/red blood cell distribution higher than the cut-off value than in anemic patients with a normal or lower hemoglobin/red blood cell distribution. CONCLUSION The results indicated that nutrition and inflammatory markers have independent prognostic significance in rectal cancer. These markers are simple, inexpensive, and useful biomarkers commonly used in clinical practice, and they were found to predict overall survival and disease-free survival independently.

Abstract
OBJECTIVE Di-n-butyl phthalate (DBP) is a ubiquitous environmental pollutant, extensively used as a plasticizer in many products, including plastics, cosmetics, and medical devices. Naringenin (NAR) is a flavonoid belonging to the flavanones subclass. It is widely distributed in several citrus fruits, bergamot, tomatoes, and other fruits. It is also found in its glycoside form (mainly naringin). Several biological activities have been ascribed to this phytochemical: antioxidant, antitumor, antiviral, antibacterial, anti-inflammatory, antiadipogenic, and cardioprotective effects. This study hypothesized that phthalates' possible reproductive damage mechanism is oxidative attack, and naringenin could have a protective effect against radical forms in the body through its antioxidant properties. MATERIALS AND METHODS Thirty-two male rats were used in our study (n=8 each). Rats were randomly divided into four groups: Control, DBP, DBP +NAR and NAR. Phthalate (DBP) and NAR were administered through gastric oral gavage (phthalate group 500 mg/kg/day DBP; NAR group 50 mg/kg/day NAR). At the end of four weeks, testis tissue samples were taken under anesthesia. Testis tissue and blood samples were collected from the four groups in this study. Histological, biochemical and spermatological analyses were conducted. RESULTS Tissue samples from the control and NAR groups showed normal histological appearance on light microscopy. The DBP group exhibited deterioration in seminiferous tubules, vascular congestion in capsule, vascular congestion between the seminiferous tubules, edema in the intestinal area and vacuolization, arrested spermatocytes in different stages of division; sloughing of cells into the seminiferous tubular lumen was observed. It was also observed that NAR treatment significantly inhibited and prevented the histopathological damage caused by DBP. Tissue TBARS, antioxidant parameters, sperm motility, sperm density and abnormal spermatozoon ratios were determined. As a result, it was shown that DBP caused oxidative damage by increasing TBARS levels and decreasing antioxidant parameters, increased abnormal sperm rate and decreased sperm motility, and concentration and histopathological damage, so the antioxidant activity of naringenin inhibited this damage. CONCLUSIONS DBP had toxic effects in rat testis tissue; NAR treatment ameliorated these effects. Further studies are warranted to confirm our findings.

Abstract
BACKGROUND We investigated associations between baseline use of immunosuppressive drugs and severity of Coronavirus Disease 2019 (COVID-19) in autoimmune hepatitis (AIH). PATIENTS AND METHODS Data of AIH patients with laboratory confirmed COVID-19 were retrospectively collected from 15 countries. The outcomes of AIH patients who were on immunosuppression at the time of COVID-19 were compared to patients who were not on AIH medication. The clinical courses of COVID-19 were classified as (i)-no hospitalization, (ii)-hospitalization without oxygen supplementation, (iii)-hospitalization with oxygen supplementation by nasal cannula or mask, (iv)-intensive care unit (ICU) admission with non-invasive mechanical ventilation, (v)-ICU admission with invasive mechanical ventilation or (vi)-death and analysed using ordinal logistic regression. RESULTS We included 254 AIH patients (79.5%, female) with a median age of 50 (range, 17-85) years. At the onset of COVID-19, 234 patients (92.1%) were on treatment with glucocorticoids (n = 156), thiopurines (n = 151), mycophenolate mofetil (n = 22) or tacrolimus (n = 16), alone or in combinations. Overall, 94 (37%) patients were hospitalized and 18 (7.1%) patients died. Use of systemic glucocorticoids (adjusted odds ratio [aOR] 4.73, 95% CI 1.12-25.89) and thiopurines (aOR 4.78, 95% CI 1.33-23.50) for AIH was associated with worse COVID-19 severity, after adjusting for age-sex, comorbidities and presence of cirrhosis. Baseline treatment with mycophenolate mofetil (aOR 3.56, 95% CI 0.76-20.56) and tacrolimus (aOR 4.09, 95% CI 0.69-27.00) were also associated with more severe COVID-19 courses in a smaller subset of treated patients. CONCLUSION Baseline treatment with systemic glucocorticoids or thiopurines prior to the onset of COVID-19 was significantly associated with COVID-19 severity in patients with AIH.

Abstract
OBJECTIVE Irinotecan (IR/CPT-11) is a semisynthetic, water-soluble derivative of the alkaloid camptothecin. It is a topoisomerase I group antineoplastic drug commonly used for the treatment of many cancer types, although it has side effects in tissues such as the testis. Curcumin (CRC) is a polyphenol compound produced from the Indian saffron root; it is used as food colouring and food flavouring. This study examined the testis-specific side effects of IR and the ability of CRC to protect against these side effects. MATERIALS AND METHODS Forty male Sprague-Dawley rats were used in our study (n = 10). The rats were randomly divided into the following four groups: control, IR, IR + CRC, and CRC. IR 10 mg/kg/day was administered intraperitoneally and CRC 100 mg/kg was administered orally. Blood and testicular samples were collected from rats in all four groups on day 30 after drug administration. Histological, biochemical, and spermatological analyses were conducted. RESULTS Testis tissue and blood samples were collected from the four groups. Tissue samples from the control and CRC groups demonstrated normal histological appearance on light microscopy. The IR group exhibited the following findings: vascular congestion in the tunica albuginea layer; tubular degeneration and vascular congestion in the interstitial area; oedema, vacuolisation, and luminised cells in the seminiferous tubule; and cells that temporarily stopped dividing at any stage of division in the seminiferous tubule epithelium. In the IR+CRC group, histopathological damage was significantly reduced by CRC treatment. Biochemical analysis showed that the level of thiobarbituric acid reactive substance (TBARS) was significantly increased in the IR group, compared with the other groups. CRC treatment significantly decreased this IR-mediated increase in TBARS level, and the TBARS level in the IR + CRC group approached the level observed in the control group. IR treatment caused significant decreases in glutathione (GSH), superoxide dismutase (SOD), glutathione peroxidase (GPx), and catalase (CAT) levels. However, CRC administration tended to ameliorate the decreases in GSH, SOD, CAT, and GPx levels. CONCLUSIONS In this study, IR had some toxic effects in rat testis tissue; these effects were ameliorated by CRC treatment. Further studies are warranted to confirm our results.

Abstract
OBJECTIVE In this study, our aim was to compare conservative treatment and surgical treatment radiologically and clinically in the treatment of pediatric Gartland type IIB SCHF, which is a controversial issue in the literature. PATIENTS AND METHODS This retrospective study included 86 patients with a Gartland type IIB humerus fracture. Forty-three patients were treated conservatively, and 43 patients were surgically treated. Radiological results were evaluated according to the Baumann angle and anterior humerus line. The Mayo Elbow Performance Score (MEPS) and Flynn's criteria were used to assess the functional evolution. RESULTS The mean MEPS was 94 for the conservative treatment group and 93 for the surgical treatment group. According to Flynn's criteria, 31 (72.09%) excellent results were obtained in patients who were treated conservatively, and 26 (60.46%) excellent results were obtained in the surgical treatment group. CONCLUSIONS The conservative and surgical treatment of Gartland type IIB SCHF is not superior to each other if anatomic reduction is achieved. Complications of each treatment can be prevented by following strict treatment principles.

Abstract
Aim: Zoonotic parasite infections affect many pregnant people around the world. Hydatid cystic disease is also a zoonotic disease caused by Echinococcus sp. This study aims to present the maternal-fetal results and clinical treatment of pregnant women diagnosed with liver hydatid cyst (CH). This zoonotic disease is discussed again in the light of current literature. Materials and Methods: Pregnant women with hydatid cyst monitored in a tertiary health center between 2018 and 2020 were evaluated. Seven cases were included in this study. We retrospectively collected and analyzed clinical data, which did not interfere with medical treatment. Results: Albendazole was started as medical therapy in six patients, and percutaneous drainage was applied to one patient. Three of our six patients who started medical treatment had to undergo surgery due to maternal complications that developed despite medical treatment. Two of our patients were delivered with a cesarean section due to the obstetric indications. Discussion: Hydatid cysts are most commonly caused by Echinococcus granulosus infection and most common in the liver. The diagnosis of liver hydatid cysts is not difficult, but pregnant women's treatment methods have some problems. Although both medical and surgical treatments are available, there is no consensus. We would also like to underscore that echinococcal disease of the liver should be kept in mind in the differential diagnosis of abdominal pain, jaundice, and/or fever, especially in endemic regions. We think that when we increase awareness about this disease, we can improve fetal and maternal outcomes by making an early diagnosis and management.

Abstract
Introduction
Increases in spontaneous activity in the neurons of the auditory cortex are presumed as the pathophysiology of tinnitus.
Objective
To investigate the effectiveness of transcranial magnetic stimulation (TMS) in the treatment of tinnitus.
Methods
A total of 62 patients between the ages of 22 and 74 with chronic subjective tinnitus were enrolled in the study. The inclusion criteria were normal findings on an otolaryngologic examination and normal ranges of complete blood count, routine biochemical parameter levels, thyroid function, air-bone gap on pure-tone audiometry, and middle-ear pressure and stapedial reflex on tympanometry. The patients were randomized into 2 groups: 40 patients were placed in the treatment for TMS (tTMS) group, and the rest (22 patients) were placed in the sham TMS group. The frequency and severity of the tinnitus, as well as the tinnitus handicap inventory (THI) score of each patient were measured before and one month after the treatment, and the values were statistically evaluated.
Results
We observed a statistically significant improvement in the tTMS group (
p
< 0.05 and
p
< 0.05 respectively) regarding the THI and tinnitus severity scores. The sham TMS group showed no significant improvement in terms of the THI (
p
> 0.05). However, the tinnitus severity showed a significant increase in this group (
p
< 0.05). The comparison of differences in the changes in the THI and the tinnitus severity scores showed a significant statistical improvement in the tTMS group compared with the sham TMS group (
p
< 0.05 and
p
< 0.05 respectively).
Conclusion
Transcranial magnetic stimulation was found to be effective in the treatment of tinnitus, and may be adopted as a treatment for tinnitus after further comprehensive studies.

Abstract
Objectives: Limited data are available from recent trials involving pregnant women to guide Helicobacter pylori infection diagnosis. There are no data about the presence of H. pylori in the amniotic fluid as well. Furthermore, the relation between amniotic fluid H. pylori and hyperemesis gravidarum (HG) has not been characterized yet. Materials and Methods: This is a prospective study conducted after obtaining approval from the Ethics Committee. Pregnant women undergoing amniocentesis were enrolled in the study. The stool antigen test assessed the presence of H. pylori in amniotic fluid. A perinatologist independently performed an amniocentesis. The obtained amniotic liquid was sent to the laboratory to evaluate H. pylori infection by stool H. pylori antigen assay. We determined the rate of H. pylori in amniotic fluid and assessed relations between H. pylori infection and pregnancy outcome, including HG. Results: Between May and September 2017, we enrolled 48 pregnant women who underwent amniocentesis to detect possible fetal malformations. Patients were divided into two groups regarding the HG status. There were significant differences between the groups in terms of H. pylori infection presence. Among them, 28 (58.3%) were found to have a positive H. pylori test in their amniotic fluid. The rate of HG was significantly higher (71.4%) in patients who tested positive for H. pylori in amniocentesis than the H. pylori-negative group (20%), (p<0.001). Conclusions: The study's main new finding is that presence of H. pylori in the amniotic fluid is possible. Our data suggest that H. pylori-infected amniotic fluid is associated with the experience of past HG. The current study may have important implications for HG detection and help identify patients who would benefit from future preventive strategies.

Abstract
OBJECTIVES This study aimed to evaluate the effect of quercetin on cochlear function and morphology, and its possible protective effect against acute cisplatin-induced ototoxicity in rats. MATERIALS AND METHODS This prospective and controlled animal study was conducted on Wistar albino rats divided into four groups. Otoacoustic emission measures were performed three days after the first infiltration in Group 1 (saline), 2 (cisplatin), and 3 (quercetin). This interval was five days for Group 4 (cisplatin+quercetin). At the end of the study, the rats were decapitated with deep anesthesia, and histological changes in the cochleas were observed by light microscopy. RESULTS Group 2 (cisplatin) revealed significant differences between the first and second measures in all frequencies. When compared to other group, the difference of the changes in Group 2 statistically significantly decreased, especially in higher frequencies. Morphologically, there were no acute changes in Group 1 and Group 3. Outer hair cell loss and the degeneration of stria vascularis and spiral ganglion were observed in both Groups 2 and 4; the damages in the latter were lesser. CONCLUSION Quercetin does not have negative effect on cochlea, and it has protective effect on cisplatin-induced ototoxicity.

Abstract
AIM The reproductive hormone levels and systemic physiology of women with hepatic cirrhosis are altered. Existing data have indicated the adverse effects of cirrhosis on both the mother and the fetus. Pregnancy is successful in most of the patients with chronic liver disease. But maternal and fetal complication rates are still high for decompensated hepatic cirrhosis. In this study, we aimed to evaluate the clinical features, etiological factors, medications, morbidity, mortality, and obstetric outcomes of pregnant women with hepatic cirrhosis. METHODS Pregnant women, who were diagnosed with maternal hepatic cirrhosis and followed up in our clinic between 2014 and 2017, were retrospectively evaluated. The pregnant women that had been followed up for hepatic cirrhosis were classified as compensated disease and decompensated disease. Eleven cases were included in this period. RESULTS The mean age of cases was 33.5 ± 5.5 years. The mean gravida number was 3.2 ± 1.1, and the mean parity number was 1.7 ± 1. Six cases were in the compensated cirrhosis stage, and 5 cases were in the decompensated cirrhosis stage. A pregnancy with decompensated cirrhosis was terminated after the fetal heart sound was negative in the 9th week of pregnancy. Spontaneous abortus occurred in one case (<20 weeks). The mean gestational week of the 9 cases was 33.3 ± 6.2. Two of the 9 cases delivered birth vaginally. Seven cases delivered by cesarean section. The mean first- and fifth-minute APGAR scores were 6.6 ± 1.41 and 8.2 ± 1.56, respectively. The mean birth weight was 2303 ± 981 g. Among 9 cases with live birth, 6 had compensated cirrhosis and 3 had decompensated cirrhosis. In the second trimester, upper gastrointestinal endoscopy was performed to all patients in terms of esophageal varices. Endoscopic band ligation was performed in 3 cases with upper gastrointestinal bleeding. The postpartum mortality did not occur. Discussion. Pregnancy is not recommended for patients with hepatic cirrhosis due to high maternal and fetal morbidity and mortality. The pregnancy course of cases with cirrhosis changes according to the stage of liver injury and severity of disease. Although the delivery method is controversial, delivery by cesarean section is recommended for patients with esophageal varices by the reason of bleeding from varices after pushing during labor. The bleeding risk must be kept in mind as coagulopathy is common in hepatic diseases. The maternal-fetal morbidity and mortality rates have been decreased by the current developments in hepatology, prevention of bleeding from varices with drugs and/or band ligation, improvement in liver transplantation, and increasing experience in this issue.

Abstract
Fabrication and characterization of flexible optical fiber bundles (FBs) with in-house synthesized high-index and low-index thermally matched glasses are presented. The FBs composed of around 15000 single-core fibers with pixel sizes between 1.1 and 10 μm are fabricated using the stack-and-draw technique from sets of thermally matched zirconium-silicate ZR3, borosilicate SK222, sodium-silicate K209, and F2 glasses. With high refractive index contrast pair of glasses ZR3/SK222 and K209/F2, FBs with numerical apertures (NAs) of 0.53 and 0.59 are obtained, respectively. Among the studied glass materials, ZR3, SK222, and K209 are in-house synthesized, while F2 is commercially acquired. Seven different FBs with varying pixel sizes and bundle diameters are characterized. Brightfield imaging of a micro-ruler and a Convallaria majalis sample and fluorescence imaging of a dye-stained paper tissue and a cirrhotic mice liver tissue are demonstrated using these FBs, demonstrating their good potential for microendoscopic imaging. Brightfield and fluorescence imaging performance of the studied FBs are compared. For both sets of glass compositions, good imaging performance is observed for FBs, with core diameter and core-to-core distance values larger than 1.6 μm and 2.3 μm, respectively. FBs fabricated with K209/F2 glass pairs revealed better performance in fluorescence imaging due to their higher NA of 0.59.

Abstract
This article describes the emergence of resistance and predictors of fatality for 1556 cases of healthcare-associated Gram-negative bloodstream infection in 2014 and 2015. The colistin resistance rate in Klebsiella pneumoniae was 16.1%, compared with 6% in 2013. In total, 660 (42.4%) cases were fatal. The highest fatality rate was among patients with Acinetobacter baumannii bacteraemia (58%), followed by Pseudomonas aeruginosa (45%), Klebsiella pneumoniae (41%), Enterobacter cloacae (32%) and Escherichia coli (28%). On multi-variate analysis, the minimum inhibitory concentrations for carbapenems [odds ratio (OR) 1.02, 95% confidence interval (CI) 1.01-1.04; P = 0.002] and colistin (OR 1.1, 95% CI 1.03-1.17; P = 0.001) were found to be significantly associated with fatality.

Abstract
BACKGROUND The aim of this study was to evaluate autonomic nervous system function by measuring heart rate variability (HRV) in patients with sarcoidosis without known cardiac manifestations. PATIENTS AND METHODS The study comprised 61 participants, including 31 patients with sarcoidosis without known cardiac manifestations and 30 healthy volunteers. All participants underwent echocardiographic examination, 12-channel electrocardiography (ECG), and 24-h Holter monitoring. HRV parameters were determined and compared between the groups. RESULTS There were no differences between groups with regard to age, body mass index, systolic and diastolic blood pressure, or heart rate at the time of admission. In the time domain analyses, the 24-h, daytime, and night-time standard deviations of all normal-to-normal R‑R interval (SDNN) values were significantly lower in patients with sarcoidosis than those in the controls. The frequency domain analyses showed that 24-h and daytime low-frequency (LF) values, 24-h, daytime, and night-time high-frequency (HF) values were significantly lower in the patient group compared with the control group, whereas the night-time LF/HF ratio was significantly higher. CONCLUSION Although Holter ECG is not a diagnostic tool for cardiac sarcoidosis, the HRV parameters, especially the night-time LF/HF values, may demonstrate increased sympathetic activation in patients with sarcoidosis.

Abstract
This study was carried out to measure the volume of the palatine tonsil in otorhinolaryngology outpatients with complaints of adenotonsillar hypertrophy and chronic tonsillitis who had undergone tonsillectomy. To date, no study has investigated palatine tonsil volume using different methods and compared with subjective tonsil size in the literature. For this purpose, we used three different methods to measure palatine tonsil volume. The correlation of each parameter with tonsil size was assessed. After tonsillectomy, palatine tonsil volume was measured by Archimedes, Cavalieri and Ellipsoid methods. Mean right-left palatine tonsil volumes were calculated as 2.63 ± 1.34 cm3 and 2.72 ± 1.51 cm3 by the Archimedes method, 3.51 ± 1.48 cm3 and 3.37 ± 1.36 cm3 by the Cavalieri method, and 2.22 ± 1.22 cm3 and 2.29 ± 1.42 cm3 by the Ellipsoid method, respectively. Excellent agreement was found among the three methods of measuring volumetric techniques according to Bland-Altman plots. In addition, tonsil grade was correlated significantly with tonsil volume.

Abstract
OBJECTIVE The neutrophil/lymphocyte ratio (NLR) has been evaluated as a new predictor of cardiovascular risk. Inflammation has been shown to be associated with various arrhythmias including supraventricular tachycardias (SVTs). In this study, we aimed to investigate the relation between NLR and SVT in patients with a documented atrial tachyarrhythmia. METHODS The study used a retrospective cross-sectional design. Patients who had SVT but were otherwise healthy were included. The exclusion criteria included drug use (except antiarrhythmic agents), morbid obesity, acute or chronic infection, inflammatory diseases, systemic diseases, and cancer. Total and differential leukocyte counts and routine biochemical tests were performed before the ablation procedure. RESULTS The study included 150 patients with SVT and 98 healthy controls. The biochemical and hematological parameters were comparable between the groups, except neutrophil and lymphocyte counts. The neutrophil count was significantly higher (4.7±1.5x103/µL versus 4.1±1.0x103/µL; p<0.001) and lymphocyte count was significantly lower (2.2±0.6x103/µL versus 2.5±0.6x103/µL; p=0.001) in the SVT group than in the control group. As a result, the SVT group had significantly higher NLR values than the control group (2.2±0.9 versus 1.7±0.5; p<0.001). In addition, NLR values were higher in patients in whom tachycardia was induced during an electrophysiological study (EPS) (2.3±0.9 versus 2.0±0.8; p=0.02). The association between NLR and SVT remained significant after multivariate analysis (odds ratio: 1.5, 95% confidence interval: 1.001-2.263, p=0.049). CONCLUSION Our study indicated that NLR values were significantly higher in patients with documented SVT than in control subjects. Inducibility of SVT during EPS was associated with higher NLR values.

Abstract
Recent studies have shown that ED is an early symptom of atherosclerosis. Fetuin-A, a glycoprotein secreted by the liver, kidneys and choroid plexus, has been linked to systemic fibrosis and calcification in human and rat studies. Deficiency of this compound may play a role in atherosclerosis and cardiovascular disease progression. The aim of the study was to examine whether serum fetuin-A level is related to erectile function or severity of ED. Sixty ED patients without cardiovascular disease were assigned to one of the three groups (mild, moderate or severe ED) depending on ED severity. Twenty healthy volunteers were included as the control group. The International Index of Erectile Function-5 questionnaire was used to measure erection quality in all four groups. Mean age, body mass index, total testosterone, low- and high-density lipoprotein cholesterol, and triglyceride levels did not significantly differ between the three erectile dysfunction and control groups (P > 0.05). The group with severe ED had a significantly lower mean fetuin-A level than the mild ED and control groups. For both mild and moderate ED groups, the mean serum fetuin-A level was significantly lower in comparison with the control group (P < 0.001). Serum fetuin-A level may be used as a supplemental biochemical parameter in preliminary evaluation of ED.

Abstract
Aflatoxins, the secondary metabolites produced by species of naturally occurring Aspergilli, are commonly found in food such as cereals, dried fruits and juice, wine, beer and spices. They are hepatotoxic and are well known human carcinogens based on evidence from human studies. Aflatoxins are an environmental risk factor for the development of hepatocellular carcinoma (HCC). Chronic hepatitis B-infected patients are at increased risk of cirrhosis, hepatic failure and liver cancer. This study was designed to determine the serum aflatoxin B1 (AFB1 ), aflatoxin B2 (AFB2 ), aflatoxin G1 (AFG1 ) and aflatoxin G2 (AFG2 ) concentrations using high-pressure liquid chromatography (HPLC) in hepatitis B-infected patients with or without cirrhosis and liver cancer, alongside healthy controls in Balıkesir, Turkey. The mean AFB1 and total AF levels in patients without liver cancer and cirrhosis were significantly higher than healthy controls. The mean AFB1 and total AF levels in patients with chronic hepatitis B and HCC were significantly higher than infected patients with or without cirrhosis. These results suggest that patients with chronic hepatitis B who are exposed to AFs are at increased risk for developing HCC, which might be prevented by reducing consumption of contaminated foods.

Abstract
OBJECTIVES In patients with heart failure, a variety of hemogram parameters are known to be of prognostic significance. This study aimed to investigate which of these parameters is/are useful in predicting one-year all-cause mortality in patients with acute decompensated heart failure (ADHF). STUDY DESIGN Patients who were hospitalized between September 2012-March 2013 in our hospital with systolic-ADHF with ejection fraction ≤40%, symptoms, and findings of congestion were enrolled retrospectively in the study. The study population was divided into two groups based on one-year-mortality. RESULTS 119 patients with ADHF (mean-age 67±14 years; 55% male) were enrolled in the study. One-year-mortality occurred in 29% of patients. Hemoglobin levels, platelet, basophil and lymphocyte counts were significantly lower, while red-cell distribution width (RDW) was found to be significantly higher in the one-year-mortality group. Neutrophil, monocyte, and eosinophil counts were similar in the two groups. Furthermore, lower estimated glomerular-filtration-rate (eGFR) and unused angiotensin-converting enzyme inhibitors/angiotensin receptor blockers (ACEI/ARB) were associated with mortality. Age, presence of hypertension, right-ventricular diameter, eGFR, ACE/ARB treatment, hemoglobin levels, RDW and platelet, leukocyte, lymphocyte, basophil, neutrophil, monocyte, and eosinophil-counts were found to have prognostic significance in univariate analysis. In multivariate analysis, decreased platelet, lymphocyte-counts and hemoglobin level on admission and unused ACE/ARB treatment at discharge (p<0.05) were found to be independent factors predicting one-year-mortality. CONCLUSION Among hematological indices; hemoglobin level, platelet and lymphocyte counts are readily available, useful and inexpensive markers for the prediction of one-year all-cause mortality in ADHF patients.

Abstract
OBJECTIVES Although atrial fibrillation (AF) is one of the most common rhythm disorders observed in clinical practice, a multicenter epidemiological study has not been conducted in our country. This study aimed to assess our clinical approach to AF based upon the records of the first multicenter prospective Atrial Fibrillation in Turkey: Epidemiologic Registry (AFTER) study. STUDY DESIGN Taking into consideration the distribution of the population in our country, 2242 consecutive patients with at least one AF attack determined by electrocardiographic examination in 17 different tertiary health care centers were included in the study. Inpatients and patients that were admitted to emergency departments were excluded from the study. Epidemiological data of the patients and the treatment administered were assessed. RESULTS The mean age of the patients was determined as 66.8 ± 12.3 years with female patients representing 60% of the study population. While the most common AF type in the Turkish population was non-valvular AF (78%), persistent/permanent AF was determined in 81% of all patients. Hypertension (%67) was the most common co-morbidity in patients with AF. While a stroke or transient ischemic attack or history of systemic thromboembolism was detected in 15.3% of the patients, bleeding history was recorded in 11.2%. Also, 50% of the patients were on warfarin treatment and 53% were on aspirin treatment at the time of the study. The effective INR level was detected in 41.3% of the patients. The most frequent cause of not receiving anticoagulant therapy was physician neglect. CONCLUSION These results demonstrate the necessity for improved quality of physician care of patients with AF, especially with regards to antithrombotic therapy.

Abstract
The aim of this study was to investigate the protective effect of Diospyros lotus (DL) on cisplatin (CP)-induced testicular damage in male rats. Twenty-eight male rats were randomly divided into four groups: group 1 - control, given isotonic saline solution; group 2 - CP 7 mg kg(-1) given intraperitoneally as single dose; group 3 - DL 1000 mg kg(-1) per day given orally for 10 days; group 4 - CP and DL given together at the same doses. CP caused a significant increase in thiobarbituric acid-reactive substances (TBARS) level and a significant decrease in superoxide dismutase (SOD), glutathione peroxidase (GPx), catalase (CAT) and glutathione (GSH) levels in rats testis tissues compared to the control group. CP caused a significant increase in lipid peroxidation in testis tissues compared to the control group, whereas DL led to a significant increase in SOD and GSH levels. However, there were no statistically significant changes in GPx and CAT levels. In addition, serum testosterone levels, sperm concentration and sperm motility were significantly decreased, but abnormal sperm rate and histological changes were increased with CP. However, these effects of CP on sperm parameters, histological changes and the tissue weights were eliminated by DL treatment. In conclusion, our study showed that the reproductive toxicity caused by CP may be prevented by DL treatment.

Abstract
Background and Objectives The etiopathogenesis of coronary artery ectasia (CAE) is not known completely. In most of the cases, CAE is associated with atherosclerosis; however, isolated CAE has a nonatherosclerotic mechanism. The association between atherosclerotic coronary artery disease and apelin has been examined in previous studies. However, the role of plasma apelin in isolated coronary artery ectasia has not been studied. In this study, we investigated the relationship between plasma apelin levels and isolated coronary artery ectasia. Subjects and Methods The study population included a total of 54 patients. Twenty-six patients had isolated CAE (53.6±8.1 years); 28 patients with normal coronary arteries (51.6±8.8 years) and with similar risk factors and demographic characteristics served as the control group. Apelin levels were measured using an enzyme-linked immunoassay kit. Results Apelin level in the CAE group was significantly lower (apelin=0.181±0.159 ng/mL) than that in the control group (apelin=0.646±0.578 ng/mL) (p=0.033). Glucose, creatinine, total cholesterol, triglyceride, low density lipoprotein cholesterol, and high density lipoprotein cholesterol levels were not significantly different between the two groups. Conclusion In this study, we showed that patients with isolated CAE have decreased plasma apelin levels compared with the control group. Based on the data, a relationship between plasma apelin and isolated CAE was determined.

Abstract
OBJECTIVES We aimed to analyze 1) overall and coronary mortality findings in the Turkish Adult Risk Factor (TARF) study survey 2012 and 2) the temporal trends in prevalence of metabolic syndrome (MetS) and its distribution across seven geographic regions. STUDY DESIGN Information on the mode of death was obtained from first-degree relatives and/or health personnel of a local health office. Information collected in survivors was based on history, physical examination of the cardiovascular system and Minnesota coding of resting electrocardiograms. RESULTS Of 1527 participants to be surveyed, 796 were examined; information was obtained on the health status in 502 subjects, and death was ascertained in 56 participants. Thirty deaths were attributed to coronary and cerebrovascular disease. Cumulative 22-year evaluation of participants in the age bracket 45-74 years revealed coronary mortality to be high, with 7.6 per 1000 person-years in men and 3.8 in women. Data used from 1754 identical subjects (median age 46 years initially), and examined in two periods 12 years apart, indicated an increase in the prevalence of MetS by 1.3% per aging of 1 year. Analysis across geographic regions showed a rise in the prevalence in the Mediterranean region, already having highest prevalence along with Southeast Anatolia, while the prevalence declined in the Marmara region and persisted to be lowest in the Aegean region. CONCLUSION The prevalence of MetS in Turkish adults aged 40 years or over, currently standing at 53%, shows significant differences across geographic regions, being highest in the two southern regions and lowest in the Aegean region.

Abstract
OBJECTIVE The prognostic value of the Global Registry of Acute Coronary Events (GRACE) risk score (GRS) and the Thrombolysis in Myocardial Infarction (TIMI) risk index (TRI) have been reported in patients with coronary artery disease (CAD). In this study, we sought to evaluate the association between TRI and the extent and severity of CAD evaluated by SYNTAX score (SS) and Gensini score in patients with ST elevation myocardial infarction (STEMI). METHODS A total of 290 patients with STEMI were included in the study. GRS and TRI were calculated on admission using specified variables. The extent and severity of CAD were evaluated using the SS and Gensini scores. The patients were divided into low (TRI ⩽19), intermediate (TRI 19-30), and high (TRI ⩾30) risk groups. A Pearson correlation analysis was used for the relationship between TRI, GRS, Gensini score and SS. RESULTS There were significant differences in the mean age (p < 0.001), admission heart rate (p < 0.001), admission systolic blood pressure (p = 0.009), SS (p < 0.001), GRS (p < 0.001) and in-hospital major adverse cardiac events (MACE) in all patients between the low, intermediate and high TRI risk groups. There was a positive significant correlation between TRI and SS (r = 0.24, p < 0.001), Gensini score (r = 0.18, p = 0.002), GRS (r = 0.74, p = 0.001) and in-hospital MACE (r = 0.29, p < 0.001). CONCLUSION TRI is significantly related to SS and Gensini score in predicting the extent and severity of CAD in patients with STEMI.

Abstract
Whether euthyroid status affects cardiovascular disease risk is unclear. We aimed to investigate whether serum thyroid-stimulating hormone (TSH) levels within the normal range are related to the risk of coronary heart disease (CHD). In participants of the Turkish Adult Risk Factor Study (mean age 52.7±11.5), in whom TSH was measured in the 2004/05 survey, cross-sectional and longitudinal analyses were performed. Subjects with TSH concentrations<0.3 and >4.2 mIU/L were excluded to ensure euthyroid status leaving 956 individuals as the study sample. Mean follow-up was 4.81±1.3 years. Men had 18% lower (p<0.001) geometric mean TSH levels (1.10 mIU/L) than women (1.35 mIU/L). Correlations of TSH with risk variables were notably virtually absent except weakly positive ones in men with age and systolic blood pressure (SBP). The age-adjusted TSH mid-tertile in men was associated with lowest lipoprotein [Lp](a), apoB, and total cholesterol values. Incident CHD was predicted in Cox regression analyses in men [HR of 2.45 (95 %CI 1.05; 5.74] and in combined sexes by the lowest compared with the highest TSH tertile, after adjustment for age, smoking status, SBP, and LDL-cholesterol. Analysis for combined prevalent and incident CHD stratified by metabolic syndrome (MetS) confirmed the independent association with the lowest TSH tertile in men, specifically in men without MetS. TSH levels within normal range, low due to partial assay failure, may manifest as independent predictors of incident CHD, particularly in middle-aged men. Autoimmune responses involving serum Lp(a) under oxidative stress might be implicated mechanistically.

Abstract
OBJECTIVE The neutrophil/lymphocyte ratio (NLR), the platelet/lymphocyte ratio (PLR), and uric acid (UA) are inflammatory markers in cardiovascular disease. However, there are not enough data on infarct-related artery (IRA) patency in ST-segment elevation myocardial infarction (STEMI). We aimed to investigate the association of NLR, PLR, and UA with IRA patency before percutaneous coronary intervention (PCI) in STEMI. METHODS The study was designed as a retrospective study. Three hundred and twenty-four consecutive patients with STEMI were divided into two groups according to pre-PCI Thrombolysis in Myocardial Infarction flow grade (TIMI). Patients with a TIMI flow grade of into the spontaneous reperfusion (SR) group, while patients with TIMI flow grade of 0, 1 and 2 were placed into the non-SR group. The χ2 and independent-samples t-test, Mann-Whitney U test, multivariate logistic regression analysis, and receiver-operator characteristic (ROC) curve analysis were used for the statistical analysis. RESULTS PLR, NLR, and UA values in the SR group were lower than in the non-SR group (p<0.004, p<0.001, p<0.001, respectively). In the multivariate analysis, serum UA level and PLR were found to be independent predictors of pre-PCI IRA patency. In the ROC curve analysis, PLR >190, UA>5.75 mg/dL, and NLR>4.2 predicted non-SR. The sensitivity and specificity of the association between low IRA TIMI flow grade and PLR were 88% and 84%, 72% and 66% for UA, and 74% and 44% for NLR, respectively. CONCLUSION We determined that PLR and UA are novel predictors of IRA patency before PCI. We suggest that PLR and UA may be used in risk-stratifying STEMI.

Abstract
OBJECTIVE In this study, we aimed to explore the association between platelet-to-lymphocyte ratio (PLR) and the severity of atherosclerosis in coronary artery disease (CAD). METHODS Clinical and laboratory data of 388 patients who underwent coronary angiography were evaluated retrospectively. Gensini score, which indicates the severity of atherosclerosis, was calculated for all of the patients. Patients with CAD were categorized as mild and severe atherosclerosis, according to their Gensini score. Eighty patients with normal coronary arteries formed the control group. Mean PLR values of the three study groups were compared. Also, PLR value was tested for whether it showed a positive correlation with Gensini score. RESULTS The mean PLR of the severe atherosclerosis group was significantly higher than that of the mild atherosclerosis and controls groups (p<0.001). Also, PLR was positively correlated with Gensini score in CAD patients. A cut-off value of 111 for PLR predicted severe atherosclerosis with 61% sensitivity and 59% specificity. Pre-procedural PLR level was found to be independently associated with Gensini score, together with WBC, age, and low HDL level, in the multivariate analysis. CONCLUSION Our study suggests that high PLR appears to be additive to conventional risk factors and commonly used biomarkers in predicting severe atherosclerosis.

Abstract
BACKGROUND The purpose of this study was to investigate the functionality of autotransplanted thyroid tissues immediately or after cryopreservation in rabbits. METHODS The study was completed with 12 rabbits randomized in 2 groups. Preoperative scintigraphies were performed for all subjects. The rabbits underwent total thyroidectomy. The first group underwent immediate thyroid autotransplantation. Thyroid tissues of the second group were cryopreserved and autoimplanted at the eighth postoperative week. The free triiodothyronine (fT3) and thyroxine (fT4) levels were monitored for 8 weeks. Postoperative scintigraphies were performed at the eigth week after autoimplantation. RESULTS The subjects in the first group reached euthyroid levels at the eighth week while none of the second group reached that level, but all showed continuous increase. Although implanted thyroid tissues of 5 of the 6 rabbits in the first group were demonstrated during the first scintigraphy, the number was only 1 in the second group. CONCLUSION Thyroid autografts were found to be functional and thought to have a potential preventing postoperative hypothyroidism.

Abstract
The aim of this study was to evaluate the relationship between hematologic indices and the Global Registry of Acute Coronary Events (GRACE) score in patients with ST-segment elevation myocardial infarction (STEMI). A total of 800 patients who consecutively and retrospectively presented with STEMI within 12 hours of symptom onset. After accounting for exclusion criteria, a total of 379 patients remained in the study. We enrolled 379 patients with STEMI (mean age 61.7 ± 13.6 years; men 73%). Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), red cell distribution width (RDW), and monocyte count were associated with increased worse GRACE risk score (P = .008, P = .012, P = .005, P = .022, respectively). In multivariate linear regression analysis, NLR, PLR, RDW, and monocyte count were found to be independent predictors of GRACE risk score. We demonstrate for the first time that PLR, RDW, and monocyte were associated with the GRACE score in patients with STEMI.

Abstract
Objective: Platelets and inflammatory cells are vital elements of acute coronary syndromes (ACS). Recent studies have shown that the plateletto-lymphocyte ratio (PLR) is associated with several malignancies; however, there are not enough data in cardiovascular diseases. Therefore, the aim of this study was to explore the association between PLR and in-hospital mortality in patients with ACS. Methods: We retrospectively collected patients with ACS undergoing coronary angiography. Total and differential leukocyte counts were measured by an automated hematology analyzer. Results: This study is single-centered and observational. In total, 587 patients with a mean age of 61.8±13.1 years (68.4% male) were enrolled in the study. Patients were divided into 3 tertiles based on PLR levels. In-hospital mortality was significantly higher among patients in the upper PLR tertile when compared with the middle and lower PLR tertile groups [29 (14.8%) vs. 17 (8.7%) and 2 (1.0%); p<0.001]. In the multiple logistic regression analysis, a high level of PLR was an independent predictor of in-hospital mortality, together with age, total leukocyte count, and creatinine. Using a cutoff point of 142, the PLR predicted in-hospital mortality with a sensitivity of 69% and specificity of 63%. Conclusion: Different from other inflammatory markers and assays, PLR is an inexpensive and readily available biomarker that may be useful for cardiac risk stratification in patients with ACS.

Abstract
OBJECTIVE We investigated the association of serum asymmetric dimethylarginine (ADMA) with metabolic syndrome (MetS), type-2 diabetes and coronary heart disease (CHD) in the general population. METHODS Cross-sectional and, at 2000 person-years' follow-up, prospective analysis. Adults with measured serum ADMA level (n=848) were analyzed using tertiles or dichotomized values. ADMA concentrations were measured by a validated commercial ELISA kit. RESULTS Dichotomized subjects of combined sexes with low (≤0.68 µmol/L) ADMA values had significantly higher fasting glucose, total cholesterol, apolipoprotein B and lower diastolic blood pressure. In linear regression analyses comprising age, smoking, triglyceride, HDL-cholesterol, C-reactive protein and waist circumference as well, creatinine was significantly and independently associated with ADMA, further in women glucose (inversely). In logistic regression analyses uniformly adjusted for age, smoking status and waist girth, prevalent MetS tended to positive independent association with ADMA tertiles only in men. Combined prevalent and incident diabetes weakly tended to be associated with the lowest (vs mid- and highest) ADMA tertiles in combined gender; and prevalent and incident CHD was not associated with ADMA tertiles in either sex. CONCLUSION Apparently "low" circulating ADMA is independently associated with fasting glucose and tends to be so with type-2 diabetes. The lack of anticipated positive associations of ADMA with cardiometabolic disorders is likely due to autoimmune responses operating against serum ADMA under oxidative stress, rendering partial failure in immunoassay.

Abstract
BACKGROUND Risks for coronary heart disease (CHD) and diabetes (T2DM) of the 'hypertriglyceridemic waist' phenotype (HtgW) warrant further investigation. We studied this issue and whether partial proinflammatory conversion of apolipoprotein (apo) A-I by lipoprotein(a) [Lp(a)] is a codeterminant. MATERIALS AND METHODS In a population-based prospective study, 1328 Turkish adults were analysed in four groups by the presence of abdominal obesity and elevated triglycerides (Htg). RESULTS LDL-cholesterol levels, significantly elevated in isolated Htg, were lower in HtgW, yet significantly higher apoB and complement C3 values existed in women with HtgW in whom also the lowest Lp(a) values prevailed. Lp(a) was linearly associated, more strongly in HtgW than in the remaining groups, with apoB and, in women inversely, with gamma-glutamyltransferase. Incident HtgW was predicted, not in men, but in women inversely by Lp(a) (OR 0.80 [95%CI 0.65; 0.97]), regardless of adjustment for relevant confounders. After adjustment for conventional risk factors, HtgW (OR 2.84) and high apoA-I/HDL-C ratio (OR 1.50) were significantly and additively associated with combined prevalent and incident CHD risk. High apoA-I and low HDL-cholesterol levels interacted therein in women. Type-2 diabetes was strongly predicted by HtgW, mediated in men by high apoA-I/HDL-C ratio. CONCLUSION HtgW is associated with excess inflammatory markers, is predicted in women paradoxically by lower circulating Lp(a) and is associated in both sexes with marked excess cardiometabolic risk to which high apoA-I/HDL-C ratio contributes additively. These findings are consistent in women with apoA-I being oxidized via aggregation to Lp(a).

Metabolic syndrome (MetS) was defined by ATP-III criteria modified for male abdominal obesity, and IFG and type 2 diabetes were identified by criteria of the American Diabetes Association. Stratification by presence of MetS was used. Outcomes were predicted providing estimates for hazard ratio (HR) obtained by use of Cox proportional hazards regression analysis in models that controlled for potential confounders.
RESULTS: In 3181 adults (aged 52 ± 11.5 years at baseline), analysis stratified by MetS, gender and IFG status distinguished normoglycemic subjects by a “hypertriglyceridemic waist” phenotype consisting of significantly higher waist circumference, fasting triglyceride and lower high-density lipoprotein-cholesterol, regardless of gender and MetS. Additionally, lipoprotein (Lp) (a) tended to be lower in (especially female) participants with MetS. Multivariable linear regression in a subset of the sample demonstrated decreased Lp (a) levels to be associated with increased fasting glucose and insulin concentrations, again particularly in women. In Cox regression analysis, compared with normoglycemia, baseline IFG adjusted for major confounders significantly predicted incident diabetes at a 3-fold HR in men and only women with MetS. Cox models for developing CHD in 339 individuals, adjusted for conventional risk factors, revealed that IFG status protected against CHD risk [HR = 0.37 (95%CI: 0.14-0.998)] in subjects free of MetS, a protection that attenuated partly in male and fully in female participants with MetS.
CONCLUSION: IFG status in non-diabetic people without MetS displays reduced future CHD risk, yet is modulated by MetS, likely due to autoimmune activation linked to serum Lp (a).

Abstract
AIM: To investigate whether serum adiponectin protects against cardiometabolic risk in a population sample with prevailing metabolic syndrome.
METHODS: Middle-aged adults representative of a general population with baseline circulating adiponectin measurements (n = 1224) were analyzed prospectively at a mean of 3.8 years’ follow-up, using continuous values or sex-specific tertiles. Total adiponectin was assayed by an ELISA kit. Type-2 diabetes was identified by criteria of the American Diabetes Association. Hypertension was defined as a blood pressure ≥ 140 mmHg and/or ≥ 90 mmHg and/or use of antihypertensive medication. Outcomes were predicted using Cox proportional hazards regression analysis in models that were controlled for potential confounders.
RESULTS: In models of multiple linear regression, sex hormone-binding globulin, fasting insulin (inverse) and, in men, age were significant independent covariates of serum adiponectin which further tended in women to be positively associated with serum creatinine. Cox regression analyses for incident coronary heart disease (CHD), adjusted for sex, age, non-HDL cholesterol, waist circumference and C-reactive protein, revealed significant inverse association with adiponectin tertiles in men but not women (HR = 0.66; 95%CI: 0.32-1.38 for highest tertile). Cox regression for type-2 diabetes in a similar model (wherein glucose replaced non-HDL cholesterol), adiponectin tertiles appeared to protect in each gender. HR for incident hypertension roughly displayed unity in each of the adiponectin tertiles (P-trend = 0.67).
CONCLUSION: High adiponectin levels failed to protect against the development of hypertension and, in women, against CHD, presumably paralleling impairment in renal function as well. Involvement of adiponectin in autoimmune complex with loss of antioxidative-antiatherogenic properties may be underlying.

Abstract
We evaluated the efficacy and tolerability of antibiotic regimens and optimal duration of therapy in complicated and uncomplicated forms of spinal brucellosis. This is a multicentre, retrospective and comparative study involving a total of 293 patients with spinal brucellosis from 19 health institutions. Comparison of complicated and uncomplicated spinal brucellosis was statistically analysed. Complicated spinal brucellosis was diagnosed in 78 (26.6%) of our patients. Clinical presentation was found to be significantly more acute, with fever and weight loss, in patients in the complicated group. They had significantly higher leukocyte and platelet counts, erythrocyte sedimentation rates and C-reactive protein levels, and lower haemoglobulin levels. The involvement of the thoracic spine was significantly more frequent in complicated cases. Spondylodiscitis was complicated, with paravertebral abscess in 38 (13.0%), prevertebral abscess in 13 (4.4%), epidural abscess in 30 (10.2%), psoas abscess in 10 (3.4%) and radiculitis in 8 (2.7%) patients. The five major combination regimens were: doxycycline 200 mg/day, rifampicin 600 mg/day and streptomycin 1 g/day; doxycycline 200 mg/day, rifampicin 600 mg/day and gentamicin 5 mg/kg; doxycycline 200 mg/day and rifampicin 600 mg/day; doxycycline 200 mg/day and streptomycin 1 g/day; and doxycycline 200 mg/day, rifampicin 600 mg/day and ciprofloxacin 1 g/day. There were no significant therapeutic differences between these antibiotic groups; the results were similar regarding the complicated and uncomplicated groups. Patients were mostly treated with doxycycline and rifampicin with or without an aminoglycoside. In the former subgroup, complicated cases received antibiotics for a longer duration than uncomplicated cases. Early recognition of complicated cases is critical in preventing devastating complications. Antimicrobial treatment should be prolonged in complicated spinal brucellosis in particular.
