(Elsevier, 2011) Karahocagil, Mustafa Kasim; Akdenin, Hayrettin; Sunnetcioglu, Mahmut; Cicek, Muttalip; Mete, Rafet; Akman, Nevzat; Yapici, Kubilay
Aim: To present the results of a cross-sectional epidemiological analysis of a familial outbreak of fascioliasis in Eastern Anatolia and to discuss the clinical, diagnostic and therapeutic properties of the patients. Materials and methods: A screening group consisting of 92 individuals from the same family with a history of watercress ingestion and a control group consisting of 30 individuals from neighboring families were included in the study. In both groups, full blood count, erythrocyte sedimentation rate, liver function tests and total IgE levels were assessed. Stool analysis was performed on three consecutive days with native, lugol and sedimentation methods. The diagnosis was based on the detection of parasite ova in the stool or alternatively based on consistent clinical, laboratory, and radiological findings or positive clinical findings in combination with a positive ELISA test. Abdominal ultrasonography and computerized tomography scans were performed on all patients. Results: 24 patients (21 women and 3 men) were diagnosed with fascioliasis. The mean age was 24.5 +/- 18.6 years (range, 5-64 years). All cases had a history of watercress ingestion, malaise, fatigue, lack of appetite, and abdominal pain. Clinical features included: weight loss was present in 18 cases (75%). dyspepsia in 12 (50%), headache in 11(45.8%), sweating in 10 (41.7%), fever and dyspnea each in 8 (33.3%), nausea and vomiting in 6 (25%), and itching in 4 (16.75). The most common laboratory abnormalities were total IgE elevation in 19 cases (79.2%) and eosinophilia in 17 (70.8%). The eosinophilia was >20% in 14 cases (58.3%) and the total IgE was >500 IU/ml in 15 cases (62.5%). Stool examination for ova was positive in 11 cases. 10 patients had positive clinical, laboratory and radiological findings. A further three patients were diagnosed based on their clinical findings and their ELISA results. All cases had positive ELISA results. All patients, except one pregnant woman, were treated with 10 mg/kg triclabendazole. Two patients required a second treatment course of triclabendazole 20 mg/kg in two divided doses due to persistence of ova in the stool. One patient who developed acute urticaria as a side effect of the drug was given three additional courses of 10 mg/kg triclabendazole in combination with prednisolone and antihistamines. The pregnant woman initially received four courses of 25 mg/kg praziquantel treatment for 1 week. As ova were still detected in her stool following delivery, she was subsequently treated with triclabendazole. Conclusions: One case of fascioliasis may indicate a familial outbreak. In the acute stage radiological investigations can assist in confirming the diagnosis. ELISA testing is a reliable and sensitive method for the diagnosis of fascioliasis during any stage of the disease and may also be useful during follow-up. (C) 2008 Elsevier B.V. All rights reserved.
Global Trends on Blastocystis Spp. Research: a Scientometric Study
(Egyptian Parasitologists United Soc - Epu, 2023) Bilden, Alican; Gurbuz, Esra; Aydemir, Selahattin; Unlu, Ahmet H.; Ekici, Abdurrahman; Alkan, Sevil; Cicek, Muttalip
Background: For many years, the classification and pathogenicity of Blastocystis was a subject of debate. The study rational is built on two hypotheses; whether this uncertainty affects the research on Blastocystis spp., and whether regional differences have an impact on diseases prevalence.Objective: The aim of this study is to guide researchers interested in blasticystosis by presenting a bibliometric review of the existing literature on blastocystosis.Material and Methods: The VOSviewer visualization methodology was used. Institutions, nations, international collaborations, journals, articles, authors, keywords, co-authors, co-citations, and citation rates from the WoS database formed the study data. A total of 1192 documents were found in the WoS database, of which 906 original articles were analyzed.Results: The articles were cited 24,065 times in total and the mean Hirsch (H) index was 74. The countries with the highest number of articles were as follows: USA (n = 93; 10.26%), Singapore (n = 79; 8.72%), China (n = 76; 8.39%), and Malaysia (n: 74; 8.17%). During the period from 2000-2013, there were a limited number of articles, while since 2014 there was a minimum of 34 publications per year. The highest number of articles was published in 2021 (n = 87) and the highest number of citations (n=3,485) was in 2021. The leading affiliation according to the number of published articles was the National University of Singapore (8.72%), University Malaya (6.62%), and Nara Women's University (4.64%). The USA, Singapore, China and Malaysia have led scientific production on Blastocystis spp.Conclusion: Due to development of recent molecular technology, the interest in Blastocystis spp. increased as recorded by ample publicatios and cited references. Development of interdisciplinary scientific research networks to include the most productive countries is crucial for Blastocystis related studies.
Single-Strand Conformation Polymorphism-Based Genetic Characterization of the Cyclospora Cayetanensis Strains Collected From Different Provinces in Turkey
(inst Agricultural Medicine, 2021) Cicek, Muttalip; Yildirim, Ibrahim Halil; Cengiz, Zeynep Tas; Karaman, Ulku
Introduction and objective. Cyclospora cayetanensis, a coccidian protozoan species, has been recently found to cause diarrhea in all age groups in immunocompetent and immunocompromised individuals in most regions of the world. This study aimed to conduct the molecular detection of C. cayetanensis and to determine the genetic diversity of the 18S ribosomal RNA (rRNA) gene sequence of C. cayetanensis isolated from individuals living in different provinces in Turkey by using PCR-single-strand conformation polymorphism (SSCP). Materials and method. A total of 22 subjects were included in the study. Fourteen of the subjects were female and eight were male, with ages ranging between 7-65 years. Stool specimens were examined using wet mount and modified acid-fast staining methods, which revealed the presence of oocysts in the samples. The 18S rRNA ITS-1 Ccits37f-GCTTGCTATGTTTTAGCATGTGG and Ccits501r-GCACAATGAATGCACACACA gene regions were used as primers. The PCR products were analyzed by agarose gel electrophoresis and visualized on a UV transilluminator. For the SSCP, the PCR products were denatured with formamide, run for 16 h in 6% (49:1) polyacrylamide gel, and then imaged with silver staining. Results. SSCP assay was performed given that the DNA strands demonstrated different folds; the DNA strands contain different nucleotides based on the PCR-SSCP results for the Cyclospora strains collected in 4 provinces. Moreover, 3 different band profiles were observed in the investigated samples. A slight mutation difference was observed among the strains collected. Conclusions. Further comprehensive studies involving more C. cayetanensis-positive specimens and utilizing different mutation screening methods are warranted to demonstrate mutation differences in Cyclopora strains in Turkey.
