Novel Patterns in High-Resolution Computed Tomography in Whipple Pneumonia.

With the use of metagenomic next-generation sequencing, patients diagnosed with Whipple pneumonia are being increasingly correctly diagnosed. We report a series of 3 cases in China that showed a novel pattern of movable infiltrates and upper lung micronodules. After treatment, the 3 patients recovered, and lung infiltrates resolved.

Whipple’s disease-A typical endoscopic finding of a rare disease

A 49-year-old female presented with a 5-month course of diarrhoea, nocturn abdominal pain, asthenia, and weight loss of 30% of her body mass in three months. The patient had also a four-year medical history of bilateral mechanic gonalgy and arthralgias of the metacarpophalangeal and interphalangeal joints, despite treatment with prednisolone. On examination the patient had hyperpigmentation of the face and thorax, low-grade fever, and a BMI of 15,8 Kg/m2. Diarrhoea was documented with watery stools seven times per day despite loperamide, brownish, with no visible blood or mucous. Since the upper GI endoscopy and colonoscopy had no macroscopic abnormalities, the patient underwent a capsule endoscopy, which revealed continuous mucosal lesion with lymphangiectasia, oedema, villous atrophy and areas of denudation with hematinic punctate from the duodenum to the ileum. Diagnosis of Whipple’s Disease was made with typical histology findings in duodenum material and a positive PCR for Tropheryma whipplei. (AU)

Whipple Disease Misdiagnosed as Lymphoma by 18 F-FDG PET/CT: A Case Study.

ABSTRACT: Whipple disease is a rare disorder caused by infection with the gram-positive bacterium Tropheryma whipplei . It can invade various organs and systems of the whole body. This case report describes a patient with invasion of multiple lymph nodes throughout the body misdiagnosed as lymphoma by PET/CT.

Whipple's disease: imaging contribution for a challenging case.

Whipple's disease is a rare and difficult-to-diagnose infectious disease, related to infection by gram-positive bacillum Tropheryma whipplei Clinical manifestations are very variable, but the classic form usually begins with recurring arthritis, followed several years later by non-specific abdominal symptoms, leading to late diagnosis. We present the case of a 52-year-old man who was admitted in the emergency department with an insidious clinical picture characterised by weight loss, abdominal pain, diarrhoea and arthralgias. An abdominal ultrasound was performed, showing findings suggestive of Whipple's disease, which, in conjunction with the clinical and laboratory findings, allowed the diagnosis to be correctly addressed. Upper endoscopy with duodenal biopsy revealed findings compatible with Whipple's disease, and the diagnosis was also confirmed through PCR techniques of blood. The patient was given antibiotic therapy, with rapid and substantial clinical improvement.

Epidemiology of Whipple's Disease in the USA Between 2012 and 2017: A Population-Based National Study.

OBJECTIVE: Prior studies on the epidemiology of Whipple's disease are limited by small sample size and case series design. We sought to characterize the epidemiology of Whipple's disease in the USA utilizing a large population-based database. METHODS: We queried a commercial database (Explorys Inc, Cleveland, OH), an aggregate of electronic health record data from 26 major integrated healthcare systems in the USA. We identified a cohort of patients with a diagnosis of Whipple's disease based on systemized nomenclature of medical terminology (SNOMED CT) codes. We calculated the overall and age-, race-, ethnicity, and gender-based prevalence of Whipple's disease and prevalence of associated diagnoses using univariate analysis. RESULTS: A total of 35,838,070 individuals were active in the database between November 2012 and November 2017. Of these, 350 individuals had a SNOMED CT diagnosis of Whipple's disease, with an overall prevalence of 9.8 cases per 1 million. There was no difference in prevalence based on sex. However, prevalence of Whipple's disease was higher in Caucasians, non-Hispanics, and individuals > 65 years old. Individuals with a diagnosis of Whipple's disease were more likely to have associated diagnoses/findings of arthritis, CNS disease, endocarditis, diabetes, malignancy, dementia, vitamin D deficiency, iron deficiency, chemotherapy, weight loss, abdominal pain, and lymphadenopathy. CONCLUSIONS: To our knowledge, this is the largest study to date examining the epidemiology of Whipple's disease. In this large population-based study, the overall prevalence of Whipple's disease in the USA is 9.8 cases per 1 million people. It affects men and women at similar rates and is more common in Caucasians, non-Hispanics, and people > 65 years old.

Systematic review of movement disorders and oculomotor abnormalities in Whipple's disease.

Whipple's disease, affecting the CNS, can cause a wide variety of symptoms. Movement disorders are very prevalent, and some are pathognomonic of the disease. This systematic review analyzed all published cases of movement disorders because of CNS Whipple's disease, providing detailed information on clinical and associated features. We have also attempted to address sources of confusion in the literature, particularly related to differing uses of the terminology of movement disorder. This comprehensive overview of Whipple's disease-induced movement disorders aims to aid neurologists in recognizing this very rare disorder and successfully reaching a laboratory-confirmed diagnosis in order to initiate appropriate therapy. © 2018 International Parkinson and Movement Disorder Society.

Whipple Disease Presenting as Cystic Brain Tumor: Case Report and Review of the Literature.

Although neurological features are commonly encountered in Whipple"s disease (WD), presentation with purely neurological patterns is uncommon. Exclusive confinement to the central nervous system (CNS) is extremely rare. In these cases, the development of an isolated cerebral mass is exceptional. In the present paper, the authors describe a case of a 68-year-old man who presented with partial seizures. The neurological examination was normal. The imaging showed a cystic lesion. This tumor-like lesion was removed by performing frontal craniotomy. A histopathological investigation revealed the presence of numerous perivascular foamy histiocytes infiltrating the brain parenchyma. The majority of these histiocytes showed Periodic acid-schiff (PAS)-positive intense staining, which is distinctive feature of cerebral WD. The diagnosis was confirmed by polymerase chain reaction (PCR) analysis of cerebrospinal fluid. There were no gastrointestinal symptoms and no PAS inclusions in intestinal mucosa. The patient received Ceftriaxone intravenously followed by oral trimethoprime-sulfamethoxazole (TMP-SMZ) for 12 months and recovered well. This case illustrates atypical WD, confined exclusively to the central nervous system.

Whipple's Disease with Long-term Endoscopic Follow-up.

A 72-year-old man presented with anorexia and 15-kg weight loss over 3 years. Endoscopy revealed yellow, shaggy mucosa alternating with erythematous, eroded mucosa in the duodenum. Biopsy specimens showed massive infiltration of periodic acid-Schiff-positive macrophages in the lamina propria, consistent with Whipple's disease. The patient was treated with intravenous ceftriaxone for four weeks, followed by oral trimethoprim-sulfamethoxazole. His condition improved, and he gradually gained weight. Although the endoscopic findings improved with continuous trimethoprim-sulfamethoxazole administration, macrophage infiltration of the duodenal mucosa persisted. However, the patient has been symptom-free for eight years.

Whipple's endocarditis presenting as ulnar artery aneurysm; if you don't look, you won't find.

A 54-year-old female patient presented to her local district general hospital with a painful, swollen left arm. Imaging revealed an ulnar artery aneurysm. The aetiology was embolic, with an echocardiogram revealing vegetations on the aortic valve. The patient was treated empirically for 6 weeks with amoxicillin and gentamicin for endocarditis. Eight months later, she had an elective aortic valve replacement for symptomatic aortic regurgitation. The valve was culture negative but analysis by 16S rDNA PCR was positive for Tropheryma whipplei In retrospect, the ulnar artery aneurysm and a history of arthralgia were attributed to an underlying diagnosis of Whipple's endocarditis. She continues on antibiotic treatment with resolution of her arthralgia and no clinical signs of infection. Once thought to be rare entity, molecular assays have revolutionised the diagnosis of Whipple's endocarditis, but this case highlights the difficulties and pitfalls in diagnosis.
