The epidemiology, Clinical Manifestations, radiology, microbiology, treatment, and prognosis of echinococcosis: Results of NENEHATUN study

Aim: Echinococcosis, caused by Echinococcus species, is an important zoonotic disease causing major health problems in humans and animals. Herein, we aimed to evaluate the epidemiology, clinical and laboratory parameters, radiological, serological, pathological, and treatment protocols of followed-up cases of hydatidosis. Methods: A total of 550 patients diagnosed with hydatid cyst disease were included in this study. Patients who were positive for one or more of the enzyme-linked immunosorbent assay or indirect hemagglutination test, pathological results, or radiological findings were examined. The data analyzed were collected from nine centers between 2008 and 2020. Records were examined retrospectively. Results: Among the patients, 292 (53.1%) were women and 258 (46.9%) were men. The patients' mean age was 44.4 +/- 17.4 years. A history of living in rural areas was recorded in 57.4% of the patients. A total of 435 (79.1%) patients were symptomatic. The most common symptoms were abdominal pain in 277 (50.4%), listlessness in 244 (44.4%), and cough in 140 (25.5%) patients. Hepatomegaly was found in 147 (26.7%), and decreased breath sounds were observed in 124 (22.5%) patients. Radiological examination was performed in all cases and serological methods were also applied to 428 (77.8%) patients. The most frequently applied serological test was IHA (37.8%). A single cyst has been found in 66% patients. Hepatic involvement occurred in 327 (59.4%), pulmonary involvement was found in 128 (23.3%), whereas both of them were recorded in 43 (7.8%) patients. Splenic involvement was only detected in nine (1.6%) patients. Echinococcus granulosus (72.5%) was most frequently detected. Cyst diameters of 56.9% of the patients were in the range of 5-10 cm. A total of 414 (75.2%) patients received albendazole as an antiparasitic. Mortality was noted in nine (1.6%) patients. Conclusion: Echinococcosis is an important public health problem in Turkey. It can affect the social, economic, and political structures of the community. Public education and awareness are extremely important

The Relation Between Serum Alpha Defensin-1 Levels with Clinical Course and Prognosis in Crimean-Congo Hemorrhagic Fever

Aim: Crimean-Congo Hemorrhagic Fever (CCHF) is a viral zoonotic infection characterized by fever and bleeding. Alpha-defensin-1 (AD-1) is an antimicrobial peptide. The aim of this study was to investigate the relationship between the clinical course and prognosis of CCHF and AD-1 serum levels, and also to examine the role of AD-1 in the pathogenesis of the disease.Material and Methods: Fifty patients diagnosed with CCHF and hospitalized at the Atatürk University Faculty of Medicine Department of Infectious Diseases and Clinical Microbiology, and 38 healthy control were included in this study. Serum AD-1 levels were measured using ELISA methods and compared between the groups.Results: Serum AD-1 levels in the patients were significantly higher than those in the control group (p=0.017). Of the patients, 18 (36%) were classified as severe clinical course, 16 (32%) as moderate clinical course, and 16 (32%) as mild clinical course. There was no statistically significant difference among the three groups in terms of serum AD-1 levels (p=0.729). Median serum AD-1 levels were 171.0 (range, 126.8-221.2) ng/ml in the fatal cases, and 118.7 (range, 91.9-183.3) ng/ml in the surviving patients, and the difference between these two groups was statistically significant (p=0.014).Conclusion: As a result, the increased serum AD-1 levels in CCHF patients, remained higher in severe course patients and in the fatal cases. On the basis of these results, AD-1 appears to indicate the clinical course and provide useful information about mortality. More extensive research should be performed to make generalizations on this subject

Relationship Between Hemodynamically Significant Ductus Arteriosus and Ischemia-Modified Albumin in Premature Infants

Hemodynamically significant ductus arteriosus (hsPDA) may alter organ perfusion by interfering blood flow to the tissues. Therefore, in infants with hsPDA, hypoxia occurs in many tissues. In this study, we aimed to investigate the diagnostic significance of serum (ischemia-modified albumin) IMA levels as a screening tool for hsPDA, and its relation to the severity of the disease in the preterm neonates. For this purpose, seventy-two premature infants with gestation age <34 weeks were included in the study. Thirty premature infants with hsPDA were assigned as the study group and 42 premature infants without PDA were determined as the control group. Blood samples were collected before the treatment and 24 h after the treatment, and analyzed for IMA levels. IMA levels in the study group (1.26 +/- 0.36 ABSU) were found to be significantly higher than control group (0.65 +/- 0.12 ABSU) (p < 0.05). In infants with hsPDA, a positive correlation was found between IMA and PDA diameter (rho = 0.876, p = 0.022), and LA/Ao ratio (rho = 0.863, p = 0.014). The cut-off value of IMA for hsPDA was measured as 0.78 ABSU with 88.89 % sensitivity, and 90.24 % specificity, 85.71 % positive predictive, 92.5 % negative predictive value [area under the curve (AUC) = 0.96; p < 0.001]. The mean IMA value of the infants with hsPDA before treatment was 1.26 +/- 0.36 ABSU, and the mean IMA value of infants after medical treatment was 0.67 +/- 0.27 ABSU (p = 0.03). We concluded that IMA can be used as a marker for the diagnosis and monitoring of a successful treatment of hsPDA

Patients with dental calculus have increased saliva and gingival crevicular fluid fetuin-A levels but no association with fetuin-A polymorphisms

ABSTRACT: Fetuin-A is a potent inhibitor of calcium-phosphate precipitation and of the calcification process, therefore it can also be related with dental calculus. Thus, we aimed to investigate a possible relationship between fetuin-A gene polymorphism and the presence of dental calculus. A possible relationship between serum, saliva and gingival crevicular fluid (GCF) levels of fetuin-A was also investigated. Fetuin-A c.742C > T and c.766C > G polymorphisms were investigated in 103 patients with or without dental calculus. Additionally, serum, saliva and GCF fetuin-A levels of patients were compared according to dental calculus presence. A significant difference was not observed in the distribution of the fetuin-A c.742C > T and c.766C > G polymorphisms between patients with or without dental calculus. Saliva and GCF fetuin-A concentrations of patients with dental calculus were statistically higher than those without dental calculus (P=0.001, P=0.036 respectively). According to our results, fetuin-A c.742C > T and c.766C > G polymorphisms were not associated with presence of dental calculus. However, higher GCF and saliva fetuin-A levels were detected in patients with dental calculus than in patients without dental calculus, which may result from an adaptive mechanism to inhibit mineral precipitation and eventually calculus formation
