BACKGROUND: Leptospirosis is a zoonotic infectious disease caused by pathogenic spirochetes of the genus Leptospira. Although it is usually asymptomatic and self-limited, severe potentially fatal illness accompanied by multi-organ failure may occur. CASE REPORT: Here we report an unusual case of severe leptospirosis successfully treated with continuous venovenous hemofiltration (CVVHF) and therapeutic plasma exchange (TPE). The patient presented with pericardial tamponade, renal failure and macrophage activation syndrome, and later suffered prolonged jaundice and sclerosing cholangitis during hospitalization in the pediatric intensive care unit (PICU)...

Immunisation with the C-terminal region of leptospiral immunoglobulin-like A protein (LigANI) has shown promising results against leptospirosis. We evaluated the humoral immune response and protection induced by LigANI associated with carboxyl multi-walled carbon nanotubes (COOH-MWCNTs), CpG oligodeoxynucleotides (CpG ODNs), or Alhydrogel. Animals immunised with CpG ODNs were unable to develop a humoral immune response, whereas immunisation with LigANI and COOH-MWCNTs produced a high level of IgG antibodies, similar to that with LigANI and Alhydrogel, but it was not protective...

Opisthorchiasis caused by Opisthorchis viverrini is an important foodborne trematodiasis in Thailand, Laos and Cambodia. Interestingly, the opisthorchiasis endemic region overlaps with an area of leptospirosis emergence. Here we report an association between opisthorchiasis and leptospirosis in Thailand. Of 280 sera collected from villagers living around the Lawa wetland complex in Khon Kaen province, 199 (71%) were seropositive for leptospirosis by immunochromatography. Individuals with O. viverrini infection had a significantly higher rate of leptospirosis than those without (P=0...

BACKGROUND: Leptospirosis is a zoonotic disease known to have wide-ranging clinical manifestations. Despite a number of published case series, culture-confirmed series are few and there is a paucity of data on Jarisch-Herxheimer reaction (JHR) associated with treatment of leptospirosis. Our objective was to describe the clinical and epidemiological factors associated with leptospirosis in an endemic area of Japan, with a focus on the occurrence of JHR, an often unrecognized and likely underestimated phenomenon...

Leptospirosis is a zoonosis caused by the spirochete Leptospira interrogans. Most cases of leptospirosis are mild to moderate, and self-limited. The course of disease, however, may be complicated by multiorgan dysfunction such as in Weil's disease. We present a case of Weil's disease with pancreatitis in a young Caucasian man residing in Hawai'i. Although leptospirosis is common in Hawai'i, few patients present with pancreatitis. This report of leptospirosis-induced pancreatitis should help raise awareness of clinicians to assess for pancreatitis when evaluating a patient with leptospirosis and acute abdominal pain...

BACKGROUND: Leptospirosis is an important reemerging zoonosis, with more than half a million cases reported annually, and is caused by pathogenic Leptospira species. Development of a universal vaccine is one of the major strategic goals to overcome the disease burden of leptospirosis. In this study, a chimeric multi-epitope protein-based vaccine was designed and tested for its potency to induce a specific immune response and provide protection against L. interrogans infection. RESULTS: The protein, containing four repeats of six T- and B-cell combined epitopes from the leptospiral outer membrane proteins, OmpL1, LipL32 and LipL21, was expressed and purified...

Pulmonary involvement is a fairly common complication of leptospirosis. A high dose of steroids is often used in the treatment of pulmonary leptospirosis. Here we report two cases who developed severe invasive fungal infections following the use of steroids for pulmonary leptospirosis. Routine use of steroids for pulmonary leptospirosis may do more harm than good as the evidence for this practice is sparse.

INTRODUCTION: There have been various studies from India describing the acute presentation and the long-term sequalae of Chikungunya (CHIKV) infection. However, there are very few studies discussing the Chikungunya-Dengue (DENV) co-infection from Western India. The present project was undertaken to study the clinical features of Dengue and Chikungunya co-infection and compare with Chikungunya mono-infection; correlate the clinical findings with seroprevalence and molecular identification of Dengue and Chikungunya using IgM ELISA and RTPCR...

BACKGROUND: Dengue is a leading cause of morbidity throughout the tropics; however, accurate population-based estimates of mortality rates are not available. METHODS/PRINCIPAL FINDINGS: We established the Enhanced Fatal Acute Febrile Illness Surveillance System (EFASS) to estimate dengue mortality rates in Puerto Rico. Healthcare professionals submitted serum and tissue specimens from patients who died from a dengue-like acute febrile illness, and death certificates were reviewed to identify additional cases...

Leptospirosis has a major impact on health in Sri Lanka but is probably grossly under-recognized due to difficulties in clinical diagnosis and lack of diagnostic laboratory services. The objective of this study was to establish and evaluate a SYBR Green-based real-time Polymerase Chain Reaction (rt-PCR) assay for early, rapid and definitive laboratory diagnosis of leptospirosis in Sri Lanka. The rt-PCR assay was established and analytical specificity and sensitivity were determined using reference DNA samples...

Leptospirosis is the most widespread zoonosis in humans worldwide. In the United States, widespread detection of antibodies to leptospirosis have been identified in feral swine (Sus scrofa) with the highest detection of serovars, Bratislava, Icterohaemorrhagiae, and Pomona. Over the past few years, feral swine populations have expanded their geographical range and distribution in the United States with reports in at least 39 of 50 states. Since feral swine serve as reservoirs for serovars that can infect humans, it is important to understand the risk of transmission...

Martinique was accepted as an associate member by the Council of Ministers of the Organization of Eastern Caribbean State since February 2015. This membership constitutes a major asset in bringing Martiniquais closer to the other Caribbean populations and should play a key role as it relates to regional cooperation especially in the domain of healthcare. Martinique and several Caribbean countries share common health issues such as; dengue, chikungunya virus, Zika Virus leptospirosis, snakebite, severe cardiovascular diseases (CVD), HTLV-1, sickle cell diseases and so on...

Leptospirosis is a zoonotic disease whose severe forms are often accompanied by kidney dysfunction. In the present study, urinary markers were studied for potential prediction of disease severity. Urine samples from 135 patients with or without leptospirosis at San Lazaro Hospital, the Philippines, were analyzed. Urine levels of defensin α1 (uDA1) were compared with those of neutrophil gelatinase-associated lipocalin (uNGAL) and N-acetyl-β-d-glucosidase (uNAG). Serum creatinine (Cr) was used as a marker of kidney injury...

Human leptospirosis is a zoonotic and potentially fatal disease that has increasingly been reported in both developing and developed countries, including France. However, our understanding of the basic aspects of the epidemiology of this disease, including the source of Leptospira serogroup Australis infections in humans and domestic animals, remains incomplete. We investigated the genetic diversity of Leptospira in 28 species of wildlife other than rats using variable number tandem repeat (VNTR) and multispacer sequence typing (MST)...

Undifferentiated febrile illness in a returning soldier is a common problem encountered by serving medical officers. A 32-year-old soldier presented to Birmingham Heartlands Hospital with fever and acute kidney injury after return from Borneo. Leptospirosis was suspected and empirical antibiotics were started before subsequent confirmation by serology and PCR. Leptospirosis is common in South-East Asia, and troops exercising in jungle areas, and in the UK, are at risk. Advice, including inpatient management when appropriate, is available from the UK Role 4 Military Infectious Diseases and Tropical Medicine Service...
