Evulation of prolidase enzyme, and galectin levels as a marker for fibrosis in patients with chronic hepatitis B.

OBJECTIVE: The fibrosis can be detected using non-invasive methods including prolidase activity, proline levels and galectin-3 (GAL-3) detection in the serum. The aim of this study was to investigate the liver fibrosis through non-invasive methods in chronic hepatitis B patients. PATIENTS AND METHODS: This prospective case control study includes 56 patients with Chronic Active Hepatitis B (CAHB), 57 patients with Inactive Hepatitis B (IHB), and 60 healthy matched control subjects. The first group included the CAHB [hepatitis B surface antigen (HBsAg): positive; HBV DNA >2,000 IU/mL; normal or high alanine aminotransferase (ALT) value] undergo a liver biopsy, while the second group included the IHB (HBsAg: positive; HBV DNA: negative; normal ALT value). The third group comprised the healthy controls. Serum prolidase enzyme activities (SPEA), proline and galectin-3 levels were measured for each group. RESULTS: Patients with CAHB had significantly higher SPEA levels (1,004.3±186.8 IU/L) than did the controls (196.5±306 IU/L) (p<0.001). Significantly higher serum GAL-3 levels were found in the CHB group compared with HBV carrier and the control groups (27.4±32.2 ng/mL, 6.5±13.4 ng/mL, 3.1±5.7 ng/mL, respectively, p<0.001). The relationship between serum prolidase activity, hidroxiprolyne and fibrosis (p<0.05). There were no significant differences in ALT levels between inactive HBV carriers and the control groups (p>0.05). CONCLUSIONS: We suppose that hidroxiprolyne levels and prolidase enzyme activity might be an indicator as a marker for fibrosis in CAHB and the evaluation of response to treatment.

Temporal Trends in the Epidemiology of HIV in Turkey.

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.

Effects of entecavir, tenofovir and telbivudine treatment on renal functions in chronic hepatitis B patients.

BACKGROUND AND STUDY AIMS: The aim of this study was to enlighten the controversy about the renal safety of entecavir, tenofovir, and telbivudine treatments in chronic hepatitis B (CHB) patients by comparing these treatments in real-world conditions. PATIENTS AND METHODS: We retrospectively enrolled 104 treatment-naive patients with CHB monoinfection into our study. Patients were treated with entecavir monotherapy (n=38), tenofovir monotherapy (n=35), or telbivudine monotherapy (n=31). We then compared and statistically analyzed the effects of these drugs on the estimated glomerular filtration rate (eGFR) over a 24-month follow-up period. RESULTS: In the entecavir group, time-dependent change in eGFR was not statistically significant (p = 0.357). There was a statistically significant increase in eGFR in the telbivudine group at 12 months (p<0.001) and at 24 months (p<0.001) and, in contrast, a statistically significant decrease in the tenofovir group at 12 months (p<0.001) and at 24 months (p<0.001). There was no significant relationship between entecavir and eGFR change (p = 0.763). We found that tenofovir and telbivudine were independent predictors of eGFR change (decrease in eGFR, p<0.001 and increase in eGFR, p = 0.001, respectively). CONCLUSIONS: We recommend close follow-up of renal functions, especially for patients treated with tenofovir. Telbivudine was superior to the other drugs in terms of renal function. We conclude that an individualized therapy program considering treatment efficacy and side effects is the best option for patients.

An investigation of the effects of the mean platelet volume, platelet distribution width, platelet/lymphocyte ratio, and platelet counts on mortality in patents with sepsis who applied to the emergency department.

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.

Comparison of snakebite cases in children and adults.

OBJECTIVE: There are very few studies that compare the snakebite cases in children and adults. The present study aimed to compare the demographic characteristics, clinical presentations, laboratory findings, and developed complications in pediatric and adult patients due to snakebites. PATIENTS AND METHODS: This study included the patients admitted to the hospital and monitored due to snakebite between July 1999 and December 2012. The condition of each patient who had been bitten was admitted to the hospital was monitored from the time of admission to the end of their hospital stay. The fact that a snakebite occurred was recorded if the subjects saw the snake or if the appearance of the puncture sites was convincingly a snakebite. RESULTS: The present work included 290 patients, of whom 123 were children and 167 were adults. The most common location of the bites was the lower extremity with 78.9% (n=97) and 63.5% (n=106) in pediatric and adult patients, respectively. All of the pediatric patients received prophylactic treatment with antibiotics, whereas 62 (37.1%) adult patients received antimicrobial treatments due to the soft tissue infection. The most common complication developed was pulmonary edema in children at a rate of 33.3% (n=41) and compartment syndrome in adult patients at a rate of 3% (n=5). CONCLUSIONS: Patients admitted to the hospital due to snakebite should be monitored for at least 12 hours, even if there is no sign of clinical envenomation. Antivenom treatment should be administered to the patients requiring clinical staging. Patients should be kept under close monitoring to prevent the development of serious complications such as cellulitis, pulmonary edema, compartment syndrome, and disseminated intravascular coagulation.

Liver involvement in patients with brucellosis: results of the Marmara study.

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.

Evaluation of adults with acute viral hepatitis a and review of the literature.

AIM: In developing countries HAV infection is very common in the first years of life and it is often asymptomatic. However especially in regions of intermediate endemicity, exposure to the virus may delay and outbreaks of hepatitis A may be encountered in adults. The aim of this study is to evaluate the clinical and laboratory findings and risk factors of adults with acute viral hepatitis A. MATERIALS AND METHODS: In present study we evaluated 203 patient with acute viral hepatitis A, who were admitted to four different hospitals of three cities of Turkey between January 2000-December 2011, retrospectively. The diagnosis of acute viral hepatitis A was performed by laboratory findings and clinically. RESULTS: In a total of 203 patients, 120 (59.1%) patients were male and 83 (40.9%) were female. Mean age of cases with acute viral hepatitis A was 24.7 +11.8 years (ranged 15 to 82 years old). Acute viral hepatitis A were seen in patient who were 15-20 years and 21-30 years old, commonly. Jaundice (74%), fatigue (68%), nausea- vomiting (56%) and dark urine (48%) were the most common symptoms in cases. Prolonged cholestasis (6.8%) was the most common atypical manifestation. Prolonged jaundice was more frequent in the cases with positive HBsAg (P < 0.001). CONCLUSIONS: Acute viral hepatitis A can cause atypical presentations such as prolonged cholestasis, acute kidney injury and fulminant hepatitis. Some precautions such as routine vaccination program, improvement of hygiene conditions and informing people about it, should be taken for reducing of acute viral hepatitis A infection incidence.

Necrotizing (malignant) otitis externa: an unusual localization of mucormycosis.

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.

Risk factors for typhoid fever among adult patients in Diyarbakir, Turkey.

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.
