Abstract
Immune reconstitution inflammatory syndrome (IRIS) is characterized by exaggerated and dysregulated inflammatory responses that occur as a result of reconstitution of adaptive or innate immunity. A wide range of microorganisms have been found to be associated with IRIS, such as human immunodeficiency virus (HIV), Mycobacterium and actinobacteria. Whipple disease (WD) is an infectious disorder caused by the Gram-positive bacterium Tropheryma whipplei (T. whipplei) and IRIS also serves as a complication during its treament. Although many of these pathological mechanisms are shared with related inflammatory disorders, IRIS in WD exhibits distinct features and is poorly described in the medical literature. Novel investigations of the intestinal mucosal immune system have provided new insights into the pathogenesis of IRIS, elucidating the interplay between systemic and local immune responses. These insights may be used to identify monitoring tools for disease prevention and to develop treatment strategies. Therefore, this review synthesizes these new concepts in WD IRIS to approach the feasibility of manipulating host immunity and immune reconstitution of inflammatory syndromes from a newer, more comprehensive perspective and study hypothetical options for the management of WD IRIS.

Abstract
Whipple’s disease (WD) is a rare systemic disease caused by gram-positive bacillus bacteria that invades multiple organs mainly the intestinal epithelium. Its manifestation is not only limited to the gastrointestinal tract but it also affects the joints, muscle and skin. This is a case of a 54-year-old male patient with a medical history of chronic arthritis presenting with bilateral progressive calves pain, anterior tibial hyperpigmentation, joints pain, anemia and weight loss. He was misdiagnosed as rheumatoid arthritis, for which he was treated by immunosuppressors for several years with no amelioration. After advanced investigations, he was found to have multiple retroperitoneal and mesenteric adenopathies, with an incidental finding of a mesojejunal mass during laparoscopy, from which the biopsies revealed the presence of histiocytosis and numerous intra-cytoplasmic particles with positive periodic acid–Schiff (PAS) suggesting the diagnosis of WD. Endoscopy was done and intestinal histology with polymerase chain reaction (PCR) test confirmed the diagnosis of WD. The patient was then treated with antibiotics (ceftriaxone and trimethoprim-sulfamethoxazole) with a remarkable clinical amelioration. To be aware of WD as a potential etiology behind malabsorption, musculoskeletal and skin abnormalities, is the first step in order to establish the diagnosis and provide adequate treatment, thus, improving the patient’s quality of life. WD is a rare, without antibiotic treatment deadly systemic infectious disease caused by the ubiquitary Gram-positive bacterium Tropheryma whipplei. This article aims to report a case marked with dermatomyositis like presentation that had a missed and delayed diagnosis.

Abstract
Whipple's disease is a very rare systemic infectious disease, and very few cases have been reported. However, it can be fatal if not diagnosed and treated appropriately. The major clinical manifestations of this disease are usually digestive and nervous system symptoms. The majority of patients are male and between 40 and 50 years old. Although respiratory symptoms of this disease have rarely been reported, they pose a serious threat to the lives of the patients, especially when they progress to severe pneumonia. During admission to the hospital, Acinetobacter baumannii infection makes treatment more difficult. While most patients are middle-aged men, more attention should be given to the diagnosis and treatment of affected young women. To our knowledge, the case presented in the study is the first case of Tropheryma whipplei infection that resulted in severe pneumonia and was complicated by A. baumannii infection during treatment. We hope that our study can serve as a reference for the diagnosis and treatment of related cases in the future.

Abstract
Numerous disorders can alter the physiological mechanisms that guarantee proper digestion and absorption of nutrients (macro- and micronutrients), leading to a wide variety of symptoms and nutritional consequences. Malabsorption can be caused by many diseases of the small intestine, as well as by diseases of the pancreas, liver, biliary tract, and stomach. This article provides an overview of pathophysiologic mechanisms that lead to symptoms or complications of maldigestion (defined as the defective intraluminal hydrolysis of nutrients) or malabsorption (defined as defective mucosal absorption), as well as its clinical consequences, including both gastrointestinal symptoms and extraintestinal manifestations and/or laboratory abnormalities. The normal uptake of nutrients, vitamins, and minerals by the gastrointestinal tract (GI) requires several steps, each of which can be compromised in disease. This article will first describe the mechanisms that lead to poor assimilation of nutrients, and secondly discuss the symptoms and nutritional consequences of each specific disorder. The clinician must be aware that many malabsorptive disorders are manifested by subtle disorders, even without gastrointestinal symptoms (for example, anemia, osteoporosis, or infertility in celiac disease), so the index of suspicion must be high to recognize the underlying diseases in time.

Abstract
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. Case presentation The case study was conducted on patients in September and November 2019. After routine examination and treatment, the results were not satisfactory. A bronchoalveolar lavage (BAL) using metagenomics next-generation sequencing was conducted on two adults who presented with fever, cough, and progressive dyspnea and who had no history of gastrointestinal symptoms, immunodeficiency diseases, or use of immunosuppressive agents. TW and Candida sp. were detected in in BAL. Conclusions This is a report of life-threatening pneumonia caused by TW combined with Candida sp. in a Chinese population.

Abstract
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.

OBJECTIVE Whipple's disease is a very rare systemic infectious disease with an annual incidence of 3 in one million, which may be fatal if not diagnosed and treated appropriately. CLINICAL PRESENTATION AND INTERVENTION Herein we describe a 49-year-old patient admitted to the hospital with symptoms of severe malabsorption and diagnosed with Whipple's disease. The diagnosis was based on the histopathological findings of small intestine biopsies and PCR analysis. CONCLUSION Whipple's disease should be kept in mind while dealing with patients with severe malabsorption, even in the absence of accompanying features of the disease.

Abstract
Objective To look for abnormalities in circulating B-cell subsets in patients with rheumatic symptoms of Whipple’s disease (WD). Method Consecutive patients seen between 2010 and 2016 for suspected inflammatory joint disease were identified retrospectively. Results of standardized immunological and serological tests and of peripheral-blood B-cell and T-cell subset analysis by flow cytometry were collected. Patients with criteria suggesting WD underwent PCR testing for Tropheryma whipplei, and those with diagnosis of WD (cases) were compared to those without diagnosis (controls). We used ROC curve analysis to evaluate the diagnostic value of flow cytometry findings for WD. Results Among 2917 patients seen for suspected inflammatory joint disease, 121 had suspected WD, including 9 (9/121, 7.4%) confirmed WD. Proportions of T cells and NK cells were similar between suspected and confirmed WD, whereas cases had a lower proportion of circulating memory B cells (IgD-CD38low, 18.0%±9.7% vs. 26.0%±14.2%, P = 0.041) and higher ratio of activated B cells over memory B cells (4.4±2.0 vs. 2.9±2.2, P = 0.023). Among peripheral-blood B-cells, the proportion of IgD+CD27- naive B cells was higher (66.2%±18.2% vs. 54.6%±18.4%, P = 0.047) and that of IgD-CD27+ switched memory B cells lower (13.3%±5.7% vs. 21.4%±11.9%, P = 0.023), in cases vs. controls. The criterion with the best diagnostic performance was a proportion of IgD+CD27- naive B cells above 70.5%, which had 73% sensitivity and 80% specificity. Conclusion Our study provides data on peripheral-blood B-cell disturbances that may have implications for the diagnosis and pathogenetic understanding of WD.

Abstract
Whipple’s disease (WD) is a rare chronic systemic infection with a wide range of clinical symptoms, routinely diagnosed in biopsies from the small intestine and other tissues by periodic acid–Schiff (PAS) diastase staining and immunohistological analysis with specific antibodies. The aim of our study was to improve the pathological diagnosis of WD. Therefore, we analyzed the potential of fluorescence in situ hybridization (FISH) for diagnosing WD, using a Tropheryma (T.) whipplei-specific probe. 19 formalin-fixed paraffin-embedded (FFPE) duodenal biopsy specimens of 12 patients with treated (6/12) and untreated (6/12) WD were retrospectively examined using PAS diastase staining, immunohistochemistry, and FISH. 20 biopsy specimens with normal intestinal mucosa, Helicobacter pylori, or mycobacterial infection, respectively, served as controls. We successfully detected T. whipplei in tissue biopsies with a sensitivity of 83% in untreated (5/6) and 40% in treated (4/10) cases of WD. In our study, we show that FISH-based diagnosis of individual vital T. whipplei in FFPE specimens is feasible and can be considered as ancillary diagnostic tool for the diagnosis of WD in FFPE material. We show that FISH not only detect active WD but also be helpful as an indicator for the efficiency of antibiotic treatment and for detection of recurrence of disease when the signal of PAS diastase and immunohistochemistry lags behind the recurrence of disease, especially if the clinical course of the patient and antimicrobial treatment is considered.
