A 9-year-old spayed female Labrador Retriever was evaluated for anorexia, lethargy, and vomiting of 5 days' duration. Laboratory abnormalities included azotemia, high liver enzyme activities, hyperchloremic metabolic acidosis, glucosuria, ketonuria, proteinuria, and aminoaciduria. These laboratory abnormalities were diagnostic of proximal renal tubular acidosis and Fanconi syndrome. Results of initial and convalescent serologic tests for leptospirosis were negative. The dog was treated with amoxicillin, sodium bicarbonate, and potassium citrate at discharge. Repeated evaluations revealed resolution of the acidosis, azotemia, proteinuria, glucosuria, ketonuria, and high liver enzyme activities. Alkali administration was gradually discontinued, and the dog was clinically normal 8 months after discharge. The dog's clinical condition appeared to have been transient in nature, a phenomenon that is rarely seen in human or veterinary medicine.

To explore the relationship between the ingestion of Agouti paca (AP) and human leptospirosis in Guyana, 19 febrile men who said they had hunted and eaten A. paca were screened for malaria, using bloodsmears, and for leptospirosis, using an enzyme immuno-assay that detects Leptospira -specific IgM. Those found positive for anti-Leptospira IgM were then evaluated further, with a microscopical agglutination test based on a limited panel of serovars from three pathogenic species of Leptospira. Although six of the 18 patients who provided suitable samples for the serology were found seropositive for acute leptospirosis, only three of the 19 patients were found smear-positive for malaria. A clinical-decision model, based on medical histories, the results of physical examinations, and the use of routine urine dipsticks, and enabling prediction of the serological results, was developed. This model, which had 83% sensitivity and 100% specificity for leptospirosis, indicated that, in the absence of serology, most febrile patients reporting AP ingestion could be correctly treated if each was checked for malaria using traditional bloodsmears. The smear-positives should be treated with antimalarial drugs whereas the smear-negatives should be treated for leptospirosis if they had any of the following: a skin rash; lymphadenopathy; abnormal urine sediment (proteinuria or haematuria); and/or no previous history of malaria. In the present study, the relative risk of leptospirosis among the patients who were smear-negative for malaria and fulfilled at least one of these four criteria was 13 (P = 0.0007). In Guyana at least, leptospirosis appears to be common among men who hunt, prepare and ingest AP. Vaccines may be the best, practical form of protection among such men.

Leptospirosis has a highly variable clinical presentation, which may be related to different infecting serovars, host factors, or a combination of these. This study investigated retrospectively 34 consecutive patients with serologically confirmed leptospirosis admitted during the period 1992-2002. On admission, the most frequent symptoms were fever (100%), headache (75%), myalgia (55%), arthralgia (45%) and vomiting (39%). Pertinent laboratory findings included lymphopenia (85%), thrombocytopenia (75%), elevated liver enzymes (87%) and renal abnormalities (proteinuria, 77%; haematuria, 58%; elevated serum creatinine, 53%). The study confirmed the variable clinical and biological symptoms of leptospirosis, and indicated that lymphopenia is a common feature of leptospirosis cases.

We retrospectively reviewed 34 consecutive patients with serologically confirmed leptospirosis admitted during years 1992-2002. Nine patients (26.5%) had respiratory symptoms on admission including cough (n = 4), shortness of breath (n = 4), cyanosis (n = 2), and hemoptysis (n = 1). Six patients had pulmonary radiographic findings including (1) diffuse, ill-defined, ground-glass density (n = 3); (2) diffuse alveolar opacities (n = 2); and (3) small nodular density (n = 1). Male/female ratio was 8/1 and mean age was 47 years. Seven patients reported their exposure source including hunting (n = 2), fishing (n = 2), fresh water swimming (n = 2), and canoeing (n = 1). All patients had fever (mean = 40.1 degrees C). Other common symptoms were headache (n = 4), vomiting (n = 3), and myalgia (n = 3). Biological abnormalities included elevated liver enzymes (n = 8), proteinuria (n = 7), lymphopenia (n = 6), hematuria (n = 5), renal failure (n = 4), anemia (n = 4), and elevated neutrophil count (n = 4). PaO(2 )was measured for 3 patients while they were breathing room air (32, 55, and 66 mmHg). Suspected diagnosis on admission included leptospirosis (n = 2), bacterial pneumonia (n = 2), intoxication, influenza, viral hepatitis, biliary tract lithiasis, and rapidly progressive glomerulonephritis (one patient each). The first serologic testing for leptospirosis was positive for 5 patients (55%). Serovar was presumptively identified for 7 patients: Australis (n = 3), Grippotyphosa (n = 2), and Icterohaemorrhagiae (n = 2). Seven patients were treated with penicillin; two patients received no antibiotics. All patients were cured. In conclusion, patients with leptospirosis may present predominantly with nonspecific pulmonary symptoms. In these patients, leptospirosis must be suspected when there is a potential exposure to rats, especially in case of high-grade fever, myalgia, hepatitis, and renal abnormalities.

The frequency of pulmonary involvement in leptospirosis is not well known in Japan. A 51-year-old man admitted with fever, bloody sputum, and general severe myalgia was found in laboratory studies to have thrombocytopenia, proteinuria, renal and liver dysfunction, and positive C-reactive protein. Chest computed tomography showed multiple tiny ill-defined nodules in both lungs. Intravenous ciprofloxacin treatment (600 mg/day) ameliorated symptoms and abnormal data. After starting therapy, we learned that he had been in contacted with rodents, and he was diagnosed with leptospirosis in a microscopic agglutination test.

A 38 year old patient presented with fever, myalgic abdominal pain, nose bleeding and acute renal failure since five days. A combination of thrombocytopenia, proteinuria, elevated CrP and creatinin is common in hemorrhagic fever with renal syndrome (HFRS) due to Hantavirus infection. The benigne form is called Nephropathia epidemica. Dialysis is infrequently required by patients with the Puumala virus. Other infection (e.g. malaria, leptospirosis, yellow fever) and systemic diseases (e.g. collagenosis or vasculitis) are considered.

Leptospirosis is among the most important zoonotic disease worldwide. Annually, millions of human cases occur worldwide, with case fatality rates ranging as high as 20-25% in some regions. The pathogenicity of the Leptospira spp is depending on the responsible serovar. Rodents are the most important primary hosts but a wide range of other mammals are also able to carry and transmit the disease as secondary hosts. Humans become infected directly through infected animal contact or indirectly with water, food, or soil containing urine from these infected animals. The main route of infection is the skin through skin abrasions, more rarely through mucosa contact and exceptionally by respiratory or digestive route. The diagnosis should be evoked on a detailed personal history evoking epidemiological context with consistent clinical and biological results. A lot of infected persons may have no symptoms at all showing a minor illness. In most cases symptoms are flu-like with fever, headache and intensive myalgia associated with hepatic cytolysis, proteinuria and thrombocytopenia. In France, the most common clinical presentation combines liver involvement and jaundice with kidney involvement. However, other sites can be involved (brain, heart and lung). The diagnosis is often obtained several weeks later by serology. Treatment for leptospirosis is based on an early antibiotic therapy with amoxicillin, or tetracycline in case of allergy, but it remains controversial whether antimicrobials produce a beneficial effect in mild human leptospirosis. For at-risk occupations, preventive treatment recommends eviction or limitation of exposure, and vaccination.

Chagasic cardiomyopathy is a common disease in Latin America, however similar clinical pictures exist that can be confused with this, as they give negative results to the tests that detects T. cruzi, like non Chagasic rural endemic chronic cardiopathy, highly common in Venezuela. Using histopathology techniques, "idiopathic cardiomyopathy" is frequently found as the cause of death when the etiology of this disease is not known. This paper presents the case of a man of 26-years-old who died of dilated cardiomyopathy secondary to leptospirosis. Clinically, in addition to the cardiac failure, jaundice, hyperbilirubinemia, transaminases increase, proteinuria and hematuria were present. Initially it was suspected Chagasic cardiomyopathy but the epidemiologic background and the parasitologic and serologic tests for T. cruzi gave negative results. The dark field microscopy videorecording of blood and urine samples, argentic impregnation and immunohistochemistry tests as well as haemoculture in EMJH medium were positive for L. interrogans serovar Pomona. Postmortem we confirmed the presence of leptospira in different tissues through of histopathology, argentic impregnation, indirect immunofluorescence and immunohistochemistry.

Autosomal dominant polycystic kidney disease (ADPKD) with nephrotic syndrome is a rare coincidence. Among 19 reported cases since 1972, focal glomerulosclerosis is the dominant reported pathology. Here, we report the 6th case of focal segmental glomerulosclerosis with ADPKD. A 29-year-old man with a history of APCDK presented with massive proteinuria. He had a history of concurrent leptospirosis and brucellosis, and trace proteinuria and mild hypertension had been diagnosed 4 years earlier. Urine study showed proteinuria (21 g/d) and hematuria. Kidney biopsy report was compatible with focal and segmental sclerosis. The patient received prednisolone and cyclosporine. After 4 months, proteinuria decreased to 600 mg/d. Patients with ADPKD who show massive proteinuria should undergo kidney biopsy. It is possible that different mutations in these patients could clarify the nature of this coincidence.
