Author(s): Iwasaki, Hiroko; Chagan-Yasutan, Haorile; Leano, Prisca Susan A; Koizumi, Nobuo; Nakajima, Chie; Taurustiati, Delsi; Hanan, Firmanto; Lacuesta, Talitha Lea; Ashino, Yugo; Suzuki, Yasuhiko; Gloriani, Nina G; Telan, Elizabeth Freda O; Hattori, Toshio

Abstract: Early diagnosis based on laboratory confirmation is essential for managing leptospirosis. This study investigated the effectiveness of a novel method of detecting leptospirosis that combines measurement of anti-Leptospira antibodies by the microscopic agglutination test (MAT), enzyme-linked immunosorbent assay (ELISA), and immunochromatographic test (ICT) and leptospiral DNA by loop-mediated isothermal amplification (LAMP) and real-time PCR in plasma and 2 types of urine pellets.

Imported Flood-Related Leptospirosis From Palau: Awareness of Risk Factors Leads to Early Treatment.

Author(s): Matono, Takashi; Kutsuna, Satoshi; Koizumi, Nobuo; Fujiya, Yoshihiro; Takeshita, Nozomi; Hayakawa, Kayoko; Kanagawa, Shuzo; Kato, Yasuyuki; Ohmagari, Norio

Abstract: We describe two Japanese travelers with leptospirosis who visited Palau. Both travelers swam in Ngardmau Falls, which was flooded for two days after typhoon Phanfone. The diagnoses were confirmed by microscopic agglutination test or polymerase chain reaction. This is the first report of leptospirosis in travelers who returned from Palau. It should be noted that choosing the appropriate test to biologically confirm leptospirosis was highly time-dependent. Awareness of the risk factors for le (more)

Spatio-temporal patterns of leptospirosis in Thailand: is flooding a risk factor?

Author(s): Suwanpakdee, S; Kaewkungwal, J; White, L J; Asensio, N; Ratanakorn, P; Singhasivanon, P; Day, N P J; Pan-Ngum, W
Source: Epidemiol Infect;143(10): 2106-15, 2015 Jul.
Abstract: We studied the temporal and spatial patterns of leptospirosis, its association with flooding and animal census data in Thailand. Flood data from 2010 to 2012 were extracted from spatial information taken from satellite images. The incidence rate ratio (IRR) was used to determine the relationship between spatio-temporal flooding patterns and the number of human leptospirosis cases. In addition, the area of flood coverage, duration of waterlogging, time lags between flood events, and a number (more)

Author(s): Saitoh, Hiroki; Koizumi, Nobuo; Seto, Junji; Ajitsu, Satoshi; Fujii, Akio; Takasaki, Satoshi; Yamakage, Shu; Aoki, Satoshi; Nakayama, Keisuke; Ashino, Yugo; Chagan-Yasutan, Haorile; Kiyomoto, Hideyasu; Hattori, Toshio
Source: Tohoku J Exp Med;236(1): 33-7, 2015.
Abstract: Leptospirosis is a zoonotic and disaster-related infectious disease. It is mainly endemic in subtropical or tropical countries and has not been reported since 2009 in the Tohoku region (northern Japan), including the Yamagata and Miyagi Prefectures. However, we experienced four patients with leptospirosis in the Tohoku region from 2012 to 2014; three patients (#1-3) live in the agricultural areas of the Yamagata Prefecture and one patient (#4) was a visitor to the Miyagi Prefecture.

Source: BMJ Open;5(5): e007008, 2015 May 14.
Abstract: OBJECTIVES: After Typhoon Morakot struck Taiwan in 2009, thousands of Taiwanese citizens were displaced to shelters for several weeks. Others were placed in urban communities where they had family members. This study aimed to investigate serological status in both groups and identify risk factors associated with seroconversion of infectious diseases. DESIGN: A longitudinal survey. SETTING: All experimental and clinical investigations were performed in a tertiary teaching hospital. PARTICIPA (more)

Abstract: This study was conducted to investigate the protective efficacy of a single dosage of 200 mg doxycycline against leptospiral infection and leptospirosis and associated risk factors among residents exposed to flooding in southern Thailand. Of 641 participants, 600 received doxycycline while 41 did not. Twenty two participants were infected with Leptospira and six developed leptospirosis. Having a laceration wound was significantly associated with leptospiral infection (odds ratio [OR] = 37.2 (more)

Geographical scale effects on the analysis of leptospirosis determinants.

Author(s): Gracie, Renata; Barcellos, Christovam; Magalhães, Mônica; Souza-Santos, Reinaldo; Barrocas, Paulo Rubens Guimarães

Abstract: Leptospirosis displays a great diversity of routes of exposure, reservoirs, etiologic agents, and clinical symptoms. It occurs almost worldwide but its pattern of transmission varies depending where it happens. Climate change may increase the number of cases, especially in developing countries, like Brazil. Spatial analysis studies of leptospirosis have highlighted the importance of socioeconomic and environmental context. Hence, the choice of the geographical scale and unit of analysis use (more)
