Shen Y, Cui SS, Teng XB, Han MF. Acute pneumonia due to Tropheryma whipplei diagnosed by metagenomic next-generation sequencing and pathology: A case report. Heliyon 2024; 10:e26747. [PMID: 38434082 PMCID: PMC10906431 DOI: 10.1016/j.heliyon.2024.e26747] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2023] [Revised: 02/17/2024] [Accepted: 02/19/2024] [Indexed: 03/05/2024] Open
Abstract
Tropheryma whipplei (TW) is a rod-shaped, gram-positive bacterium that, when chronically infects humans, can lead to multi-system pathologies, including joint pain, abdominal pain with diarrhea and weight loss, myocarditis, pericarditis, and neurologic inflammation. Moreover, acute infections can lead to bronchopulmonary infections, bacteraemia, and acute diarrhea. However, fewer cases of acute pneumonia due to TW have been reported, and this diagnosis is not well founded. Herein, we report a case of acute pneumonia caused by a TW infection. The patient, a middle-aged man, underwent bronchoscopic alveolar lavage, and the metagenomic next-generation sequencing of the lavage fluid suggested TW infection. A lung puncture biopsy tissue specimen was also positive based on periodic acid-Schiff staining. After confirming the diagnosis, the patient was administered ceftriaxone for anti-infection treatment, improving clinical symptoms and lung imaging results. Therefore, in cases where conventional anti-infective treatment is ineffective for patients with acute pneumonia, we should consider the possibility of TW infection, conduct prompt pathogenetic examination, and provide timely treatment after diagnosis to improve overall patient prognosis.

Hydroxychloroquine: Key therapeutic advances and emerging nanotechnological landscape for cancer mitigation. Chem Biol Interact 2023; 386:110750. [PMID: 37839513 DOI: 10.1016/j.cbi.2023.110750] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2023] [Revised: 09/12/2023] [Accepted: 10/05/2023] [Indexed: 10/17/2023]
Abstract
Hydroxychloroquine (HCQ) is a unique class of medications that has been widely utilized for the treatment of cancer. HCQ plays a dichotomous role by inhibiting autophagy induced by the tumor microenvironment (TME). Preclinical studies support the use of HCQ for anti-cancer therapy, especially in combination with conventional anti-cancer treatments since they sensitize tumor cells to drugs, potentiating the therapeutic activity. However, clinical evidence has suggested poor outcomes for HCQ due to various obstacles, including non-specific distribution, low aqueous solubility and low bioavailability at target sites, transport across tissue barriers, and retinal toxicity. These issues are addressable via the integration of HCQ with nanotechnology to produce HCQ-conjugated nanomedicines. This review aims to discuss the pharmacodynamic, pharmacokinetic and antitumor properties of HCQ. Furthermore, the antitumor performance of the nanoformulated HCQ is also reviewed thoroughly, aiming to serve as a guide for the HCQ-based enhanced treatment of cancers. The nanoencapsulation or nanoconjugation of HCQ with nanoassemblies appears to be a promising method for reducing the toxicity and improving the antitumor efficacy of HCQ.

Abstract
Whipple's disease is a rare infectious disease with multiple clinical manifestations. The disease is named after George Hoyt Whipple, who first recorded the illness in 1907 after conducting the autopsy of a 36-year-old man with weight loss, diarrhea, and arthritis. Under the microscope, Whipple discovered a rod-shaped bacterium in the patient's intestinal wall, which was not confirmed as a new bacterial species until 1992, when it was named Tropheryma whipplei.Recurrence of Whipple's disease can occur years after an initial diagnosis and often manifests with extraintestinal symptoms such as arthritides or skin efflorescences, years before a gastrointestinal complaint. However, the simultaneous occurrence of primary hyperparathyroidism in the present case is a hitherto unknown clinical picture and opens up new questions and perspectives in the context of diagnostics and therapy.

Abstract
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. The prevalence of Whipple's disease was 4.6 per 1 million hospitalizations during the study period. Whipple's disease admissions were significantly older than other hospitalizations, with a mean age of 60.2 ± 1.6 years compared to 50.0 ± 0.1. Males were more likely to have Whipple's disease and represented approximately two-thirds of hospitalizations. A disproportionate number of admissions occurred in the Midwest. Patients with Whipple's disease were most commonly admitted for gastrointestinal disease, followed by systemic infection, cardiovascular/circulatory disease, musculoskeletal disease, respiratory disease, and neurological disease. High mortality was seen in admissions for central nervous system (CNS) disease. Whipple's disease has heterogeneous presentations for inpatient admissions, and disproportionately affects older males. High hospitalization rates in the Midwest support environmental and occupational disease transmission likely from the soil. Hospitalists should be aware of the various acute, subacute, and chronic presentations of this disease, and that acute presentations may be more common in the inpatient setting.

Whipple's Disease: Diagnostic Value of rpoB Gene PCR from Peripheral Blood Mononuclear Cells. Mol Diagn Ther 2019; 22:459-469.

Abstract
INTRODUCTION Chronic infection with Tropheryma whipplei, known as Whipple's disease (WD), classically affects the gastrointestinal tract, but any organ system may be affected, and isolated manifestations occur. Reliable diagnosis based on a combination of periodic acid-Schiff (PAS) staining, T. whipplei-specific immunohistochemistry (IHC), and polymerase chain reaction (PCR) from duodenal biopsies may be challenging in cases without classical gastrointestinal infection, so the need for additional diagnostic materials is urgent. OBJECTIVE Our objective was to evaluate additional diagnostic possibilities for WD. METHODS We analyzed samples from 20 patients with WD and 18 control subjects in a prospective observational pilot study. In addition to WD diagnosis by PAS staining, T. whipplei-specific IHC and PCR of duodenal or extra intestinal tissues, whole EDTA blood, peripheral blood mononuclear cells (PBMCs) and PBMC fractions enriched with or depleted of cluster of differentiation (CD)-14+ cells were examined using T. whipplei rpoB gene PCR. RESULTS Tropheryma whipplei DNA was detected in 35 of 60 (58.3%) preparations from 16 of 20 patients with WD, most of whom lacked gastrointestinal signs and characteristic PAS-positive duodenal macrophages. CONCLUSION This study provides evidence for the potential suitability of blood, particularly PBMCs, as material to assist in the diagnosis of WD via rpoB gene real-time PCR. Thus, PCR from blood preparations can be helpful for diagnostic decision making in atypical cases of WD.

Abstract
INTRODUCTION Hydroxychloroquine (HCQ) is most frequently used in the treatment of systemic inflammatory diseases. Cardiac complications of anti-malarial drugs are uncommon, and most of the time are the result of a long-term exposition. In this case, cardiotoxicity is the consequence of the lysosomal dysfunction and the result of intracytoplasmic granular material inclusions. CASE REPORT We report a 77-year-old woman who presented a very early and reversible cardiotoxicity, probably related to the quinidine like effect of the HCQ, 10 days after initiation of therapy for Whipple endocarditis. CONCLUSION We discuss the different mechanisms of cardiotoxicity of anti-malarial drugs and their clinical manifestations.
