Whipple's disease of the CNS

Whipple's disease, an extremely rare, chronic infection caused by Tropheryma whipplei, an actinobacterium ubiquitously present in the environment, is a multisystemic condition that can affect several organs. Therefore, Whipple's disease should always be considered by physicians working across various branches of medicine, including internal medicine, rheumatology, infectious diseases, gastroenterology, haematology, and neurology. Initially, Whipple's disease is challenging to diagnose due to both its rarity and non-specific clinical features, almost indistinguishable from rheumatological conditions...

Whipple's disease is a rare systemic disease caused by a  Tropheryma whipplei  infection. Although older literature reports a low rate of incidence, case reports continue to rise due to increased awareness of the disease. Classic Whipple's disease presents as weight loss, diarrhea, and arthralgia and may involve the heart, central nervous system (CNS), or any other organ system. Some patients with Whipple's disease do not have the classic signs and symptoms of the disease.  We present a case of Whipple's disease in a patient with poor appetite, weight loss, and granulomatous inflammation of various organs, including the kidneys and spleen, mimicking sarcoidosis...

Whipple disease is a rare multisystemic infectious process caused by Tropheryma whipplei. Classical clinical manifestations include chronic diarrhea, malabsorption, weight loss, and arthralgias. Cases of endocarditis and isolated involvement of the central nervous system have also been reported. Isolated vascular complications are not common with this disease. Vascular manifestations are mainly described as systemic embolization from underlying endocarditis. We report two consecutive cases of mycotic pseudoaneurysms resulting from Whipple disease treated with successful vascular reconstruction using autologous vein grafting...

Ependymomas account for 10% of all malignant pediatric central nervous system tumors. Standard therapy includes maximal safe surgical resection, followed by focal radiation. Despite the aggressive therapy, progression-free survival is poor. Most ependymoma relapses occur locally at the original tumor site. Extraneural presentations of ependymoma are extremely rare, and no standard of care treatment exists. We present a single-institution case series of 3 patients who experienced extraneural relapses of supratentorial ependymoma and describe their treatment and outcome...

Whipple's disease is a rare multiorgan systemic disease caused by Tropheryma whipplei infection that may present with a wide range of signs and symptoms. This study aim to comprehensively review and determine the inpatient prevalence, mortality, risk factors, and reasons for hospitalization of patients with Whipple's disease. ICD-10 codes were used to identify admissions with Whipple's disease during the years 2016 to 2018. Characteristics of admissions with and without Whipple's disease were compared. The most common reasons for hospitalization were identified in admissions with Whipple's disease...

Background: Whipple disease (WD) is an infection caused by Tropheryma whipplei , which might present in three different forms: classical, localized, and isolated in the central nervous system (CNS). Methods: We report the result of a systematic review of the literature on WD unusually presenting with exclusively neurological symptoms, including two previously unpublished cases. A description of two cases with isolated CNS WD was performed, as well as a literature search in Cochrane, Scielo , and PubMed ...

BACKGROUND AND PURPOSE: To assess the clinical spectrum of central nervous system (CNS) involvement as well as cerebrospinal fluid (CSF) and neuroimaging findings in patients with Whipple's disease (WD) and to analyze the association of neurological symptoms with CSF and imaging findings. METHODS: Neurological involvement was retrospectively analyzed in a series of 36 patients diagnosed with WD at a single center between 1992 and 2019. Findings of 81 comprehensive CSF examinations from 36 patients, including polymerase chain reaction (PCR) tests for Tropheryma whipplei (TW) in CSF from 35 patients, were systematically evaluated...

Composite pleomorphic xanthoastrocytoma-ganglioglioma (PXA-GG) is an extremely rare central nervous system neoplasm with 2 distinct but intermingled components. Whether this tumor represents a "collision tumor" of separate neoplasms or a monoclonal neoplasm with divergent evolution is poorly understood. Clinicopathologic studies and capture-based next generation sequencing were performed on extracted DNA from all available PXA-GG at 2 medical centers. Five PXA-GG were diagnosed in 1 male and 4 female patients ranging from 13 to 25 years in age...

Whipple disease (WD) is a rare systemic infection caused by Tropheryma whipplei (T. whipplei) . Its clinical features are broad, and atypical clinical patterns such as the involvement of the heart, lungs, or the central nervous system (CNS) can occur. We report a case of a 58-year-old man who had been previously diagnosed with classic WD; he was evaluated for functional decline, extreme somnolence, and recurrent admissions for hydrocephalus. The patient was diagnosed with a neurologic relapse of WD after a positive  T...

BACKGROUND: Entrectinib is a TRKA/B/C, ROS1, ALK tyrosine kinase inhibitor approved for the treatment of adults and children aged ≥12 years with NTRK fusion-positive solid tumors and adults with ROS1 fusion-positive non-small-cell lung cancer. We report an analysis of the STARTRK-NG trial, investigating the recommended phase 2 dose (RP2D) and activity of entrectinib in pediatric patients with solid tumors including primary central nervous system tumors. METHODS: STARTRK-NG (NCT02650401) is a phase 1/2 trial...

OBJECTIVE: Whipple's disease (WD) is a systemic, chronic, relapsing disease caused by Tropheryma whipplei, which can mimic signs and symptoms of various clinical entities. Typical manifestations are represented by gastrointestinal and systemic symptoms, among which neurological ones are frequent. We present the case of a patient with WD and rapidly progressive cognitive impairment and a review of literature aimed to report epidemiological, clinical, neuroimaging, and laboratory findings of cognitive impairment associated with WD...

Hyperkinetic movement disorders are characterized by the presence of abnormal involuntary movements, comprising most notably dystonia, chorea, myoclonus, and tremor. Possible causes are numerous, including autoimmune disorders, infections of the central nervous system, metabolic disturbances, genetic diseases, drug-related causes and functional disorders, making the diagnostic process difficult for clinicians. Some diagnoses may be delayed without serious consequences, but diagnosis delays may prove detrimental in treatable disorders, ranging from functional disabilities, as in dopa-responsive dystonia, to death, as in Whipple's disease...

Tropheryma whipplei is a bacterium associated with Whipple's disease, which commonly manifests as weight loss, arthralgia, and diarrhea. The most frequently involved organs comprise the heart and eyes, in addition to the central nervous system. Few studies have explored the relationship between T. whipplei and pneumonia. Herein, we report three patients with interstitial lung disease (ILD) of unknown cause, whose bronchoalveolar lavage fluid (BALF) were evaluated via Nanopore sequencing. In our in-house BALF Nanopore platform, human DNA was removed with saponin, to improve the reads ratio of microorganisms/host...

INTRODUCTION: Whipple's disease (WD) is a rare multi-systemic disorder caused by actinomycetes, Tropheryma whipplei. It presents with weight loss, arthralgia, and diarrhea and may involve the heart, lung, or central nervous system. The use of immunosuppressive medications or underlying immunodeficiency states are associated risk factors. Six cases in transplant recipients have so far been reported worldwide. We describe our experience of WD in renal transplant recipients. METHODS: All renal transplant recipients who presented with diarrhea and were diagnosed with WD on duodenal biopsy from 2016 till 2019 were included...

Whipple's disease is a multisystem disorder and responds well to antibiotic therapy if treated timely. It is seen in the fourth to fifth decades of life with a male to female ratio of 10:1. It mainly affects the intestine, the central nervous system, and joints. To the best of our knowledge, we present the first case of duodenal Whipple's disease in an Indian female, who presented with hyperpigmentation and chronic diarrhea with malabsorption. Whipple's disease was diagnosed based on specific upper GI endoscopic and histopathology findings...

We report a 26-year-old man with left chest pain for 4 days. His chest CT showed a cavity in the left upper lung. Tuberculosis was suspected first, but metagenomics next generation sequencing (mNGS) in bronchoalveolar lavage fluid only detected Tropheryma whipplei . Tropheryma whipplei is the pathogen of Whipple's disease. The most frequently involved organs are the eyes, heart, and central nervous system. Pulmonary parenchymal involvement is rare. To our knowledge, this is the first reported case of pulmonary cavity caused by Tropheryma whipplei ...

BACKGROUND: Whipple's disease is a chronic infectious disease caused by the Gram-positive bacterium Tropheryma whipplei (TW), which not only affects the gastrointestinal tract and causes malabsorption of nutrients, but several other systems, such as the cardiovascular system, central nervous system, the joints, and the vascular system, can also be simultaneously involved. The aim of this report was to be able to alert the clinician to severe pneumonia caused by TW combined with Candida sp...

SIGNIFICANCE: Whipple disease is a rare chronic, systemic bacterial infection that predominantly affects the small intestine but also other organs of the body. When left untreated, it can be not only vision threatening but also life threatening because of its central nervous system involvement. Therefore, early detection and treatment are important. PURPOSE: We report a rare case of unilateral optic disc edema as a critical identifying sign of Whipple disease. CASE REPORT: An asymptomatic 49-year-old African American man presented for an eye examination and was found to have optic nerve edema of the right eye...
