Leptospirosis Followed by Kawasaki-Like Disease: Case Report From an Adult Swiss Patient and Review of the Literature.

ABSTRACT: Kawasaki disease (KD) is a vasculitis that mostly occurs in children, but rare cases in adults have been reported. We describe the case of a 43-year-old Swiss male who developed symptoms compatible with KD 7 weeks after leptospirosis, which was presumably acquired after swimming in a creek in the Swiss Alps. We performed a literature review and identified 10 other cases (all in children), in which Kawasaki-like disease was diagnosed in the context of leptospirosis. Outcome was favourable in most cases, including our patient. This exceptional case demonstrates both the possibility of autochthonous cases of leptospirosis in Switzerland as well as a possible association of leptospirosis with Kawasaki-like disease.

Project description:BACKGROUND:The presentation of clinical leptospirosis has been historically associated with animal workers, slaughterhouse workers and medical veterinarians. This association has shifted to be related to flooding events and outdoor activities; few cases are related to high-risk factors found in immunosuppressed patients. Scarcely a handful of cases have serological evidence of immune response against Leptospira serovar Bratislava representing serogroup Australis, a serovar associated with poor reproductive performance in swine and horses, and recently with cats. CASE PRESENTATION:Herein, we describe a rare clinical presentation of disseminated Leptospira infection in an immunosuppressed 65-year-old woman. She was admitted to the emergency room with fever, bacteraemia, bilateral uveitis and pulmonary involvement. The patient denied outdoor activities; she only had wide exposure to faeces and urine from cats living in her home. Her medical history included idiopathic thrombocytopenic purpura (ITP) diagnosed at the age of 18. She did not respond to medical treatment, and a splenectomy was performed. At age 60, she was diagnosed with Chronic Myeloid Leukemia (CML), and was treated with a tyrosine kinase inhibitor (TKI) -Imatinib. The patient voluntarily discontinued the treatment for the last 6 months. After extensive workup, no microorganisms were identified by the commonly used stains in microbiology. The diagnosis was performed through dark-field microscopy, microagglutination test (MAT), Leptospira genus-specific PCR, the IS1500 PCR for identification of pathogenic species, and 16S based sequencing for the genus identification. CONCLUSION:Immunosuppressed patients may acquire uncommon infections from ubiquitous microorganisms. In this case, serology evidence of exposure to Leptospira serovar Bratislava by MAT and the presence of the Leptospira genus were identified. It should be on mind for the diagnosis in otherwise healthy patients, and thoroughly search on splenectomised patients exposed to animals. Additionally, this report highlights the usefulness of PCR for diagnosis of this potentially life-threatening illness.

Project description:Background: One of the most serious complications of cranial radiotherapy is the development of radiation-induced glioma, which is estimated to occur in 1 to 4% of patients who have received cranial irradiation and has a worse prognosis than sporadic glioblastoma. To date, owing to its rarity, no standard of care has been established for radiation-induced glioma. Although comprehensive genetic analysis has recently uncovered the molecular characteristics of radiation-induced glioma, the full picture remains unclear, and the molecular features associated with treatment response and prognosis are poorly understood. Case presentation: A 45-year-old man presented with generalized seizures caused by multiple brain tumors involving the right frontal lobe, thalamus, and brainstem. The patient had a history of whole-brain radiotherapy for the recurrence of Burkitt's lymphoma at the age of 12. He underwent craniotomy, and the histological diagnosis was a high-grade glioma with isocitrate dehydrogenase-wildtype, which was presumed to be a radiation-induced glioma that developed 33 years after whole-brain irradiation. The Heidelberg DNA-methylation brain classifier most closely matched diffuse pediatric-type high-grade glioma, receptor tyrosine kinase-1 subtype, which is a typical methylation class of radiation-induced glioma. Methylation-specific polymerase chain reaction showed that the O6-methylguanine-DNA methyltransferase gene promoter was unmethylated. Next-generation sequencing identified CDKN2A/B deletion as well as co-amplification of several receptor tyrosine kinase-encoding genes including PDGFRA, KIT, and KDR, which are all located on chromosome 4q12. Amplification of this region is present broadly across cancers and is associated with a poor prognosis in sporadic glioblastoma. Nevertheless, the patient received conventional chemoradiotherapy with temozolomide. Subsequent multimodal imaging with magnetic resonance imaging and 11C-methionine positron emission tomography revealed complete remission of all lesions. Two years later, the patient is currently alive with a favorable performance status. Conclusions: Despite radiation-induced glioma with molecular features suggestive of an aggressive phenotype, our patient unexpectedly responded well to conventional chemoradiotherapy, resulting in complete remission that is exceptional in sporadic glioblastoma. Our case indicates that some of the radiation-induced gliomas may have distinct molecular characteristics involved in the therapeutic response that differ from those of sporadic glioblastomas.
