BACKGROUND: Leptospirosis is the most widespread zoonosis. Chronic human
infection and asymptomatic colonization have been reported. However, renal
involvement in those with leptospira chronic exposure remains undetermined.
METHODS AND FINDINGS: In 2007, a multistage sampling survey for chronic kidney
disease (CKD) was conducted in a southern county of Taiwan, an area with a high
prevalence of dialysis. Additionally, an independent cohort of 88 participants
from a leptospira-endemic town was followed for two years after a flooding in
2009. Risks of CKD, stages of CKD, associated risk factors as well as kidney
injury markers were compared among adults with anti-leptospira antibody as
defined by titers of microscopic agglutination test (MAT). Of 3045 survey
participants, the individuals with previous leptospira exposure disclosed a lower
level of eGFR (98.3 ± 0.4 vs 100.8 ± 0.6 ml/min per 1.73 m2, P < 0.001) and a
higher percentage of CKD, particularly at stage 3a-5 (14.4% vs 8.5%), than those
without leptospira exposure. Multivariable linear regression analyses indicated
the association of leptospiral infection and lower eGFR (95% CI -4.15 to -1.93, P
< 0.001). In a leptospiral endemic town, subjects with a MAT titer ? 400 showed a
decreased eGFR and higher urinary kidney injury molecule-1 creatinine ratio
(KIM1/Cr) level as compared with those having lower titers of MAT (P < 0.05).
Furthermore, two participants with persistently high MAT titers had positive
urine leptospira DNA and deteriorating renal function. CONCLUSIONS AND
SIGNIFICANCE: Our data are the first to show that chronic human exposure of
leptospirosis is associated significantly with prevalence and severity of CKD and
may lead to deterioration of renal function. This study also shed light on the
search of underlying factors in areas experiencing CKD of unknown aetiology
(CKDu) such as Mesoamerican Nephropathy.
