Primary duodenal tuberculosis misdiagnosed as tumor by imaging examination:A case report

BACKGROUND Primary duodenal tuberculosis is very rare.Due to a lack of specificity for its presenting symptoms,it is easily misdiagnosed clinically.Review of the few case reports and literature on the topic will help to improve the overall understanding of this disease and aid in differential diagnosis to improve patient outcome.CASE SUMMARY A 71-year-old man with a 30-plus year history of bronchiectasis and bronchitis presented to the Gastroenterology Department of our hospital complaining of intermittent upper abdominal pain.Initial imaging examination revealed a duodenal space-occupying lesion;subsequent upper abdominal contrastenhanced computed tomography indicated duodenal malignant tumor.Physical and laboratory examinations showed no obvious abnormalities.In order to confirm further the diagnosis,electronic endoscopy was performed and tissue biopsies were taken.Duodenal histopathology showed granuloma and necrosis.In-depth tuberculosis-related examination did not rule out tuberculosis,so we initiated treatment with anti-tuberculosis drugs.At 6 mo after the antituberculosis drug course,there were no signs of new development of primary lesions by upper abdominal computed tomography,and no complications had manifested.CONCLUSION This case emphasizes the importance of differential diagnosis for gastrointestinal diseases.Duodenal tuberculosis requires a systematic examination and physician awareness.

Serum metabolic profiling of traditional Chinese medicine syndromes in patients with diarrhea-predominant irritable bowel syndrome

Objective:The clinical symptoms of diarrhea-predominant irritable bowel syndrome(IBS-D)can be effectively improved by traditional Chinese medicine(TCM)treatment,based on the usage of specific therapies for different TCM syndromes.However,in the stage of diagnosis,the standard criteria for the classification of TCM syndrome were still deficient.Through serum metabolic profiling,this study aimed to explore potential biomarkers in IBS-D patients with different TCM syndromes,which can assist in diagnosis of the disease.Methods:Serum samples were collected from healthy controls(30 cases),IBS-D patients with LiverStagnation and Spleen-Deficiency syndrome(LSSD,30 cases),Yang Deficiency of Spleen and Kidney syndrome(YDSK,11 cases)and Damp Abundance due to Spleen-Deficiency syndrome(DASD,22 cases).Serum metabolic profiling was conducted by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry.The potential biomarkers were screened by orthogonal partial least square-discriminate analysis,while metabolic pathways undergoing alterations were identified by pathway enrichment analysis in Metabo Analyst 4.0.Results:Overall,34 potential biomarkers were identified in LSSD group,36 in YDSK group and 31 in DASD group.And the 13 metabolites shared by three groups were determined as the potential biomarkers of IBS-D.Glycerophospholipid metabolism was disturbed significantly in IBS-D patients,which may play a role in IBS-D through inflammation.What’s more,three TCM syndromes have the specific potential biomarkers in glycerophospholipid metabolism.Conclusion:The serum metabolomics revealed that different TCM syndrome types in IBS-D may have different metabolic patterns during disease progression and glycerophospholipid metabolism was one of the pathways,whose metabolism was disturbed differently among three TCM syndromes in IBS-D.Therefore,the specific potential biomarkers in glycerophospholipid metabolism of three TCM syndromes in IBS-D can serve as the objective indicators,which can facilitate the TCM-syndrome objective classification of IBS-D.
