A case of Weil' disease is described in a 32-year-old patient complicated by subarachnoid haemorrhage from ruptured cerebral aneurysm and anterolateral myocardial infarction. The differentiation of the complications in strict meaning of the word from inflammatory and toxic changes in the course of leptospirosis is often difficult.

Although the risks of contracting Weil's disease in the UK are small, it can be a serious illness. Recently the disease has attracted public interest. This interest has prompted confusion and anxiety among recreational water user groups such as canoeists who had not previously seen themselves as being particularly at risk. In this paper, the experience of symptoms associated with Weil's disease among canoeists, their understanding and perceptions of the disease, and their compliance with preventive advice on the British Canoe Union (BCU) warning card, have been studied. Gaps in understanding and of adherence to preventive advice were identified. Accordingly, it was concluded that health education for canoeists could be improved. Consideration is being given by the BCU to the value of preparing a canoeist instructors' training pack.

Monoclonal antibodies against etiological agents of Weil's disease were produced by cell fusion technology. Twenty hybridomas were produced through the fusion of P3X63Ag8 .653 cells with spleen cells from BALB/c mice immunized against Leptospira interrogans serovar icterohaemorrhagiae RGA strain and serovar copenhageni Shiromizu and M20 strains. Reactivities of the antibodies produced by the hybridomas were determined by the microscopic agglutination test. Among the five hybridoma antibodies to the RGA strain, two reacted specifically to serovar icterohaemorrhagiae, two reacted to serovar icterohaemorrhagiae at a high titer and serovar copenhageni at a low titer, and one reacted to serovars icterohaemorrhagiae, copenhageni, pyrogens, and canicola. Of the ten hybridoma antibodies to the Shiromizu strain, one reacted specifically to serovar copenhageni, seven reacted to both serovars copenhageni and icterohaemorrhagiae at almost the same titer, and two exhibited intermediate properties. Of the five hybridoma antibodies to the M20 strain, three reacted to both serovars copenhageni and icterohaemorrhagiae at almost the same titer, one reacted to serovar copenhageni at a low titer and serovar icterohaemorrhagiae at a high titer, and one reacted to serovars copenhageni, icterohaemorrhagiae, and pyrogens. The results revealed that each serovar has its own antigen(s) and their common antigens. In addition, 20 strains of leptospires were recently isolated and tested with three monoclonal antibodies characterized by different reactivities. Twenty strains were clearly identified by their antibodies, i.e., 16 strains were identified as serovar icterohaemorrhagiae and three strains were identified as serovar copenhageni. The remaining strain, which was not agglutinated by three antibodies, was identified as serovar autumnalis by an agglutination test with immune rabbit sera.

A 44-year-old black male presented with fever, myalgia and weakness. He had elevated blood urea nitrogen, creatine phosphokinase and serum glutamic-oxaloacetic transaminase. During the first 6 days of this undiagnosed illness azotemia increased, a pericardial friction rub occurred, and hematuria was present. On the 7th day bilateral subconjunctival hemorrhages, anterior uveitis, and peripapillary cotton-wool spots were noted. This combination of findings suggested leptospirosis, which was subsequently confirmed by specific antibody titers. Therapeutic response was achieved with high-dose systemic steroids.

Leptospirosis is characterised by a broad spectrum of clinical manifestations varying from inapparent infection to fulminant fatal disease. Severe leptospirosis characterised by profound jaundice is referred to as Weil's disease. In the present study 20 patients of leptospirosis, of which 7 belonged to Weil's disease, were diagnosed based on the demonstration of IgM antileptospira antibody and supported by clinical correlation and appropriate biochemical markers. Overall, the male and female ratio was 17:3 and the same ratio for the Weil's disease was 6:1. The most common presentation involved fever, malaise and myalgia. Conjunctival congestion was found in 75% of the cases and jaundice was encountered in 90% of the cases. The prognosis of all these patients, including that of Weil's disease was excellent. Early recognition and initiation of antibiotic therapy were found to be important.
