| acute q fever hepatitis in taiwan. | we report a case of a chronic hepatitis b carrier with an episode of acute hepatitis. the patient presented with a headache, arthralgias, jaundice and fever. while the laboratory tests mimicked chronic hepatitis b with an acute exacerbation, lipogranulomatous changes seen in the liver biopsy strongly suggested the presence of q fever. serology testing for coxiella burneti proved positive and the patient responded to tetracycline therapy. while previously unreported in taiwan, q fever is importan ... | 1995 | 7620101 |
| acute q fever: first case report in taiwan. | a 70-year-old retired fisherman presented with fever, chills and headache for four days. the clinical presentation was mild, including a self-limiting fever, pneumonia and elevated liver enzyme levels. acute q fever was proved by a four-fold rise of phase ii igg antibodies. interestingly, the man denied any animal contact or travelling over the past year. this case may suggest that q fever should be added to the list of differential diagnoses for acute febrile disease in taiwan. | 1993 | 7908577 |
| q fever in taiwan. | although q fever, a rickettsial disease caused by coxiella burnetii, is supposed to occur sporadically worldwide, there is only one case report of this disease in taiwan. we examined the antibody of q fever to evaluate the status of q fever in taiwan. | 1994 | 8087717 |
| acute q fever as a cause of acute febrile illness of unknown origin in taiwan: report of seven cases. | acute q fever, caused by coxiella burnetii has been well documented in western countries, but only recently identified in taiwan. seven cases diagnosed by indirect fluorescent antibodies to phase ii antigens of c. burnetii are reported. the patients were all men and a history of animal contact could be traced in most cases. clinical manifestations were high fever, chills, relative bradycardia and elevated serum aminotransferases. therapy with tetracycline or clarithromycin resulted in defervesce ... | 1997 | 9136520 |
| seroprevalence of coxiella burnetii infection in southern taiwan. | the emergence of infection with coxiella burnetii, the causative organism of q fever, has been only recently recognized in taiwan. several cases of acute q fever infection have been described, but the prevalence of antibodies to c. burnetii in the general population in taiwan has not been reported. thus, we studied the seroprevalence of c. burnetii infection in southern taiwan. | 2000 | 10743344 |
| acute hepatitis with or without jaundice: a predominant presentation of acute q fever in southern taiwan. | acute q fever was previously regarded as an uncommon infectious disease in taiwan but has been increasingly recognized recently. acute febrile illness, hepatitis, and pneumonia are the 3 most common manifestations of this condition, whereas jaundice is rarely reported among patients with acute q fever. we report 2 cases of acute q fever with jaundice and multi-organ involvement. the first patient presented with fever, severe headache, and acute abdomen necessitating laparotomy and was complicate ... | 2004 | 15181492 |
| acute q fever: an emerging and endemic disease in southern taiwan. | acute q fever is a worldwide zoonosis caused by coxiella burnetii infection. in taiwan, cases of acute q fever increased during 3 y of observation, especially at kaohsiung county and city in southern taiwan. from 15 april 2004 to 15 april 2007, a total of 67 cases of acute q fever were identified at e-da hospital located at kaohsiung county. 19 (28.4%) patients had a history of travel in rural areas and only 1 had been outside southern taiwan. 21 (31.3%) patients had a history of animal contact. ... | 2008 | 17852909 |
| molecular detection and characterization of spotted fever group rickettsiae in taiwan. | rickettsioses are emerging infectious diseases caused by rickettsiae in association with arthropods. we report the detection of spotted fever group rickettsiae (sfgr) in taiwan using molecular methods. phylogenetic analyses of the 17-kd protein and citrate synthase (glta) genes showed that sfgr twkm01 detected in rhipicephalus haemaphysaloides ticks was most similar to rickettsia rhipicephali. three twkm01 isolates were obtained from three individual r. haemaphysaloides ticks. small, intracellul ... | 2007 | 17984347 |
| clinical prediction of endemic rickettsioses in northern taiwan--relevance of peripheral blood atypical lymphocytes. | several rickettsioses are endemic in taiwan. they are under-reported not only because of ignorance but also due to difficulty in recognition caused by their nonspecific manifestations, which overlap with other acute febrile illnesses. we conducted a retrospective study to delineate distinctive clinical features of rickettsiosis, in order to develop a system for differential diagnosis of rickettsiosis. | 2008 | 19122916 |
| acute q fever and scrub typhus, southern taiwan. | acute q fever and scrub typhus are zoonoses endemic to southern taiwan. among the 137 patients with acute q fever (89, 65.0%) or scrub typhus (43, 31.4%), we identified 5 patients (3.6%) who were co-infected with coxiella burnetii and orientia tsutsugamushi. | 2009 | 19861068 |
| identification of risk factors of coxiella burnetii (q fever) infection in veterinary-associated populations in southern taiwan. | the first case of q fever in taiwan was reported in 1993. the disease is considered to be emerging in taiwan, but the route of transmission has remained unclear. the annual number of confirmed q fever cases has been increasing up to more than 100 cases since 2005, comparing with less than 30 before 2003. the purpose of this study was to determine the seroprevalence and risk factors of coxiella burnetii infection in veterinary-associated populations in southern taiwan. a total of 228 serum sample ... | 2010 | 19968850 |
| clinical characteristics of q fever and etiology of community-acquired pneumonia in a tropical region of southern taiwan: a prospective observational study. | the clinical characteristics of q fever are poorly identified in the tropics. fever with pneumonia or hepatitis are the dominant presentations of acute q fever, which exhibits geographic variability. in southern taiwan, which is located in a tropical region, the role of q fever in community-acquired pneumonia (cap) has never been investigated. | 2014 | 25033402 |
| association of human q fever with animal husbandry, taiwan, 2004-2012. | in taiwan, q fever cases in humans began increasing in 2004 and peaked in 2007 but dramatically declined in 2008 and 2011. cases were significantly correlated with the number of goats. the decline might be associated with the collateral effects of measures to control goat pox in 2008 and 2010. | 2015 | 26583537 |
| human spotted fever group rickettsioses are underappreciated in southern taiwan, particularly for the species closely-related to rickettsia felis. | despite increased identification of spotted fever group rickettsioses (sfgr) in animals and arthropods, human sfgr are poorly characterized in taiwan. | 2014 | 24755560 |
| the epidemiology and characteristics of q fever and co-infections with scrub typhus, murine typhus or leptospirosis in taiwan: a nationwide database study. | q fever (qf) is a worldwide zoonosis associated with outbreaks. only a few nationwide studies regarding the surveillance and epidemiology of human qf have been reported. although qf is endemic in taiwan, a nationwide database investigation of the epidemiology and characteristics of qf and its associations with scrub typhus (st), murine typhus (mt) and leptospirosis (ls) has never been reported. we analysed nationwide databases of suspected qf, st, mt and ls cases from october 2007 to december 20 ... | 2016 | 27966835 |
| identification of factors for physicians to facilitate early differential diagnosis of scrub typhus, murine typhus, and q fever from dengue fever in taiwan. | dengue fever, rickettsial diseases, and q fever are acute febrile illnesses with similar manifestations in tropical areas. early differential diagnosis of scrub typhus, murine typhus, and q fever from dengue fever may be made by understanding the distinguishing clinical characteristics and the significance of demographic and weather factors. | 2017 | 25648664 |
