Primary hepatic tuberculosis:A rare but fatal clinical entity if undiagnosed

Hepatic tuberculosis particularly in the absence of military tuberculosis is rare.It can occur as a primary case or due to reactivation of an old tubercular focus.We report case of a 24 year old married female who died of primary hepatic tuberculosis.She had no evidence of tuberculosis elsewhere.Appropriale treatment initiated early can result in marked recovery whereas failure to recognize this entity can prove to be fatal.

Isolated hepatic tuberculosis associated with portal vein thrombosis and hepatitis B virus coinfection:A case report and review of the literature

BACKGROUND While tuberculosis(TB)itself is a common disease,isolated TB of the liver is a rare entity.Tubercular involvement of the liver is more commonly a part of a disseminated disease of the hepatic parenchyma.In contrast,isolated hepatic TB spread through the portal vein from the gastrointestinal tract is seldom encountered in clinical practice,with only a few sporadic cases and short series available in the current literature.Vascular complications,such as portal vein thrombosis(PVT),have rarely been reported previously.CASE SUMMARY A 22-year-old man was hospitalized with complaints of a 3-mo history of fever and weight loss of approximately 10 kg.He had a 10-year hepatitis B virus(HBV)infection in his medical history.Contrast-enhanced computed tomography(CECT)confirmed hepatosplenomegaly,with hypodensity of the right lobe of the liver and 2.1 cm thrombosis of the right branch of the portal vein.A liver biopsy showed epithelioid granulomas with a background of caseating necrosis.ZiehlNelson staining showed acid-fast bacilli within the granulomas.The patient was diagnosed with isolated hepatic TB with PVT.Anti-TB therapy(ATT),including isoniazid,rifapentine,ethambutol,and pyrazinamide,was administered.Along with ATT,the patient was treated with entecavir as an antiviral medication against HBV and dabigatran as an anticoagulant.He remained asymptomatic,and follow-up sonography of the abdomen at 4 mo showed complete resolution of the PVT.CONCLUSION Upon diagnosis of hepatic TB associated with PVT and HBV coinfection,ATT and anticoagulants should be initiated to prevent subsequent portal hypertension.Antiviral therapy against HBV should also be administered to prevent severe hepatic injury.

Misidentification of hepatic tuberculosis as cholangiocarcinoma:A case report

BACKGROUND Hepatic tuberculosis(TB)is uncommon clinically.Because of a lack of specific signs,characteristic symptoms and clinical manifestations and because pathological samples are difficult to obtain,hepatic TB is easily missed or misdiagnosed.CASE SUMMARY A 62-year-old Chinese man presented with jaundice for 1 wk and no abnormal laboratory tests other than elevated bilirubin,aminotransferases and C-reactive protein.Computed tomography(CT)of the abdomen showed a mass in the left lobe of the liver and hepatic hilum with striped calcified foci.Mild enhancement was visible at the edges,along with extensive intrahepatic biliary ductal dilatation in the right lobe of the liver.In the arterial phase of both CT and magnetic resonance imaging,the main trunk and right branch of the portal artery were partially visualized.Magnetic resonance cholangiopancreatography(MRCP)indicated that the left lobe of the liver and most of the bile ducts in the hilum were not visible.Pathological examination revealed coagulative necrosis,and granulomatous nodules were seen around areas of necrosis;therefore,TB was considered.CONCLUSION Hepatic tuberculosis is easily misdiagnosed or missed on imaging.Percutaneous puncture biopsy is the most useful tool for definitive diagnosis.

Propolis modulates cellular biochemistry, antioxidants, cytokine profile, histological and ultra-morphological status against antituberculosis drugs induced hepatic injury

To evaluate hepatic injury induced by antituberculosis drugs(ATDs) when administered orally for 2, 4, 6 and 8 weeks and the therapeutic potential of propolis(bee hive product) against ATDs induced hepatic injury. Methods: The ATDs were administered for 8 weeks as well as propolis extract at three different doses(100, 200, 400 mg/kg) conjointly for 8 weeks in rats. Silymarin(50 mg/kg) was given as positive control. Animals were euthanized after 8 weeks; blood and liver samples were collected to perform various biochemicals, serological and histopathological and ultramorphological studies. Results: Significant increase(P < 0.05) in aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, triglyceride and cholesterol along with reduction in glucose and albumin level were noted after ATDs induced hepatic injury. Significant increase(P < 0.05) in lipid peroxidation, triglyceride, cholesterol and CYP2E1 activity; decline in reduced glutathione, catalase, superoxide dismutase, glutathione reductase, glutathione peroxidase, glucose-6-phosphatase dehydrogenase activity were observed after ATDs intoxication. Due to presence of a wide range of flavonoids and polyphenols in propolis extract, its administration reduced hepatic injury and maintained biochemical indices towards control. Histopathological and electron microscopic observations indicated hepatoprotective potential of propolis at cellular level whereas, TNF-α, IL-6 and IGF-1 confirmed therapeutic potential of propolis at molecular level. Conclusions: It can be concluded that propolis possess hepatoprotective potential against ATDs induced hepatic injury that may prove itself as a clinically useful natural product in management of drug induced liver injury.

Diagnosis and management of severe pulmonary and extrapulmonary tuberculosis in critically ill patients:A mini review for clinicians

Among critically ill patients,severe pulmonary and extrapulmonary tuberculosis has high morbidity and mortality.Yet,it is a diagnostic challenge given its nonspecific clinical symptoms and signs in early stages of the disease.In addition,management of severe pulmonary and extrapulmonary tuberculosis is complicated given the high risk of drug-drug interactions,drug-disease interactions,and adverse drug reactions.To help clinicians acquire an up-to-date approach to severe tuberculosis,this paper will provide a narrative review of contemporary diagnosis and management of severe pulmonary and extrapulmonary tuberculosis in critically ill patients.

Primary gastroduodenal tuberculosis presenting as gastric outlet obstruction:A case report and review of literature

BACKGROUND Mycobacterium tuberculosis(TB)is the causative agent of TB,a chronic granulo-matous illness.This disease is prevalent in low-income countries,posing a significant global health challenge.Gastrointestinal TB is one of the three forms.The disease can mimic other intra-abdominal conditions,leading to delayed diagnosis owing to the absence of specific symptoms.While gastric outlet obs-truction(GOO)remains a frequent complication,its incidence has declined with the advent of proton pump inhibitors and Helicobacter pylori eradication therapy.Gastroduodenal TB can cause upper gastrointestinal hemorrhage,obstruction,and malignancy-like tumors.CASE SUMMARY A 23-year-old male presented with recurrent epigastric pain,distension,nausea,vomiting,and weight loss,prompting a referral to a gastroenterologist clinic.Endoscopic examination revealed distorted gastric mucosa and signs of chronic inflammation.However,treatment was interrupted,possibly owing to vomiting or comorbidities such as human immunodeficiency virus infection or diabetes.Subsequent surgical intervention revealed a dilated stomach and diffuse thickening of the duodenal wall.Resection revealed gastric wall effacement with TB.CONCLUSION Primary gastric TB is rare,frequently leading to GOO.Given its rarity,suspicions should be promptly raised when encountering relevant symptoms,often requiring surgical intervention for diagnosis and treatment.

Interferon-gamma release assays as a tool for differential diagnosis of gastrointestinal tuberculosis

In this editorial,we comment on an article published in a recent issue of the World Journal of Clinical Cases.There is a pressing need for reliable tools for diagnosing tuberculosis(TB)of the gastrointestinal tract.Despite advancements in the diagnosis and treatment,TB remains a global health challenge.Ali et al demon-strated that TB may mimic gastrointestinal conditions,such as gastric outlet obstruction,causing a delay in the diagnosis.Furthermore,the latter complication is frequently observed during infections,including Helicobacter pylori,and rarely is related to TB,as in the presented case.In line with this,we think that laboratory tests based on interferon-gamma release assays can be a helpful tool for diagnosing latent TB paced in the gastrointestinal tract.Innovative strategies and approaches for diagnosing latent/active extra pulmonary TB are crucial for establishing the diagnosis early and enhancing treatment strategies to mitigate the global burden of TB.

psk1 virulence gene-induced pulmonary and systemic tuberculosis in a young woman with normal immune function:A case report

BACKGROUND Tuberculosis is a chronic infectious disease and an important public health pro-blem.Despite progress in controlling tuberculosis,the incidence of tuberculosis in China is still very high,with 895000 new cases annually.This case report des-cribes the investigation of a case of severe disseminated tuberculosis in a young adult with normal immune function,conducted to ascertain why a Mycobacterium tuberculosis(M.tuberculosis)strain caused such severe disease.CASE SUMMARY A previously healthy 28-year-old woman presented to our hospital with a 1-mo-nth history of fever and fatigue.She was diagnosed with severe disseminated pulmonary tuberculosis,spinal tuberculosis with paravertebral abscesses,and tuberculous meningitis.M.tuberculosis was isolated from bronchoal-veolar lavage fluid.She was treated with standard antituberculous therapy and underwent debridement,bone graft,and internal fixation surgery for spinal tuberculosis.She responded to therapy and regained her ability to walk following the surgery.We analysed the whole-genome sequence of the strain and designated it BLM-A21.Additional M.tuberculosis genomes were selected from the Virulence Factor Database(http://www.mgc.ac.cn/cgi-bin/VFs/genus.cgi?Genus=Mycobacterium)for comparison.An evolutionary tree of the BLM-A21 strain was built using PhyML maximum likelihood software.Further gene analysis revealed that,except for the pks1 gene,BLM-A21 had similar virulence genes to the CDC 1551 and H37Rv strains,which have lower dissemination.CONCLUSION We speculate that the pks1 virulence gene in BLM-A21 may be the key virulence gene responsible for the wide-spread dissemination of M.tuberculosis infection in this previously healthy adult with normal immune function.

Revisiting tuberculosis as a cause of gastric outlet obstruction:Insights from a case report

Gastroduodenal tuberculosis(GD-TB)is exceptionally rare.The clinical manifestations of gastrointestinal TB are diverse and non-specific,which makes diagnosis difficult,leading to delayed diagnosis and high mortality.As a peer-reviewer of World Journal of Clinical Cases,I would like to share my opinion on the article published by this journal.The patient had no family history of TB or contact with people with TB.Primary GD-TB presenting as gastric outlet obstruction and normal findings of thoracic computed tomography increased the difficulty of diagnosis and treatment in this patient.The diagnosis and treatment scheme of this typical case have reference value for the clinical treatment of GD-TB.

Diagnosis and treatment experience of atypical hepatic cystic echinococcosis type 1 at a tertiary center in China

BACKGROUND Some hydatid cysts of cystic echinococcosis type 1(CE1)lack well-defined cyst walls or distinctive endocysts,making them difficult to differentiate from simple hepatic cysts.AIM To investigate the diagnostic methods for atypical hepatic CE1 and the clinical efficacy of laparoscopic surgeries.METHODS The clinical data of 93 patients who had a history of visiting endemic areas of CE and were diagnosed with cystic liver lesions for the first time at the People's Hospital of Xinjiang Uygur Autonomous Region(China)from January 2018 to September 2023 were retrospectively analyzed.Clinical diagnoses were made based on findings from serum immunoglobulin tests for echinococcosis,routine abdominal ultrasound,high-frequency ultrasound,abdominal computed tomography(CT)scan,and laparoscopy.Subsequent to the treatments,these patients underwent reexaminations at the outpatient clinic until October 2023.The evaluations included the diagnostic precision of diverse examinations,the efficacy of surgical approaches,and the incidence of CE recurrence.RESULTS All 93 patients were diagnosed with simple hepatic cysts by conventional abdominal ultrasound and abdominal CT scan.Among them,16 patients were preoperatively diagnosed with atypical CE1,and 77 were diagnosed with simple hepatic cysts by high-frequency ultrasound.All the 16 patients preoperatively diagnosed with atypical CE1 underwent laparoscopy,of whom 14 patients were intraoperatively confirmed to have CE1,which was consistent with the postoperative pathological diagnosis,one patient was diagnosed with a mesothelial cyst of the liver,and the other was diagnosed with a hepatic cyst combined with local infection.Among the 77 patients who were preoperatively diagnosed with simple hepatic cysts,4 received aspiration sclerotherapy of hepatic cysts,and 19 received laparoscopic fenestration.These patients were intraoperatively diagnosed with simple hepatic cysts.During the followup period,none of the 14 patients with CE1 experienced recurrence or implantation of hydatid scolices.One of the 77 patients was finally confirmed to have CE complicated with implantation to the right intercostal space.CONCLUSION Abdominal high-frequency ultrasound can detect CE1 hydatid cysts.The laparoscopic technique serves as a more effective diagnostic and therapeutic tool for CE.

Perianal tuberculous ulcer with active pulmonary,intestinal and orificial tuberculosis:A case report

BACKGROUND Orificial tuberculosis is a rare type of tuberculosis,which is easy to be misdiagnosed,and can cause great damage to the perianal skin and mucosa.Early diagnosis can avoid further erosion of the perianal muscle tissue by tuberculosis bacteria.CASE SUMMARY Here,we report a case of disseminated tuberculosis in a 62-year-old male patient with a perianal tuberculous ulcer and active pulmonary tuberculosis,intestinal tuberculosis and orificial tuberculosis.This is an extremely rare case of cutaneous tuberculosis of the anus,which was misdiagnosed for nearly a year.The patient received conventional treatment in other medical institutions,but specific treatment was delayed.Ultimately,proper diagnosis and treatment with standard anti-tuberculosis drugs for one year led to complete cure.CONCLUSION For skin ulcers that do not heal with repeated conventional treatments,consider ulcers caused by rare bacteria,such as Mycobacterium tuberculosis.

Road to recompensation:BavenoⅦcriteria and transjugular intrahepatic portosystemic shunt in liver cirrhosis

Liver cirrhosis has long been considered a point of no return,with limited hope for recovery.However,recent advancements,particularly the Baveno VII criteria and the utilization of transjugular intrahepatic portosystemic shunt(TIPS),have illuminated the concept of hepatic recompensation.In this editorial we comment on the article by Gao et al published in the recent issue.This editorial provides a comprehensive overview of the evolution of understanding cirrhosis,the criteria for recompensation,and the efficacy of TIPS in achieving recompensation.We discuss key findings from recent studies,including the promising outcomes observed in patients who achieved recompensation post-TIPS insertion.While further research is needed to validate these findings and elucidate the mechanisms underlying recompensation,the insights presented here offer renewed hope for patients with decompensated cirrhosis and highlight the potential of TIPS as a therapeutic option in their management.

Malignant hepatic vascular tumors in adults: Characteristics,diagnostic difficulties and current management

Malignant vascular tumors of the liver include rare primary hepatic mesenchymal tumors developed in the background of a normal liver parenchyma. Most of them are detected incidentally by the increased use of performing imaging techniques. Their diagnosis is challenging, involving clinical and imaging criteria, with final confirmation by histology and immunohistochemistry. Surgery represents the mainstay of treatment. Liver transplantation(LT) has improved substantially the prognosis of hepatic epithelioid hemangioendothelioma(HEHE), with 5-year patient survival rates of up to 81%, based on the European Liver Intestine Transplantation AssociationEuropean Liver Transplant Registry study. Unfortunately, the results of surgery and LT are dismal in cases of hepatic angiosarcoma(HAS). Due to the disappointing results of very short survival periods of approximately 6-7 mo after LT, because of tumor recurrence and rapid progression of the disease, HAS is considered an absolute contraindication to LT. Recurrences after surgical resection are high in cases of HEHE and invariably present in cases of HAS. The discovery of reliable prognostic markers and the elaboration of prognostic scores following LT are needed to provide the best therapeutic choice for each patient.Studies on a few patients have demonstrated the stabilization of the disease in a proportion of patients with hepatic vascular tumors using novel targeted antiangiogenic agents, cytokines or immunotherapy. These new approaches,alone or in combination with other therapeutic modalities, such as surgery and classical chemotherapy, need further investigation to assess their role in prolonging patient survival. Personalized therapeutic algorithms according to the histopathological features, behavior, molecular biology and genetics of the tumors should be elaborated in the near future for the management of patients diagnosed with primary malignant vascular tumors of the liver.

Alterations in the gut microbiome after transjugular intrahepatic portosystemic shunt in patients with hepatitis B virus-related portal hypertension

BACKGROUND Gut microbiota(GM)affects the progression and response to treatment in liver diseases.The GM composition is diverse and associated with different etiologies of liver diseases.Notably,alterations in GM alterations are observed in patients with portal hypertension(PH)secondary to cirrhosis,with hepatitis B virus(HBV)infection being a major cause of cirrhosis in China.Thus,understanding the role of GM alterations in patients with HBV infection-related PH is essential.AIM To evaluate GM alterations in patients with HBV-related PH after transjugular intrahepatic portosystemic shunt(TIPS)placement.METHODS This was a prospective,observational clinical study.There were 30 patients(with a 100%technical success rate)recruited in the present study.Patients with esophagogastric variceal bleeding due to HBV infection-associated PH who underwent TIPS were enrolled.Stool samples were obtained before and one month after TIPS treatment,and GM was analyzed using 16S ribosomal RNA amplicon sequencing.RESULTS One month after TIPS placement,8 patients developed hepatic encephalopathy(HE)and were assigned to the HE group;the other 22 patients were assigned to the non-HE group.There was no substantial disparity in the abundance of GM at the phylum level between the two groups,regardless of TIPS treatment(all,P>0.05).However,following TIPS placement,the following results were observed:(1)The abundance of Haemophilus and Eggerthella increased,whereas that of Anaerostipes,Dialister,Butyricicoccus,and Oscillospira declined in the HE group;(2)The richness of Eggerthella,Streptococcus,and Bilophila increased,whereas that of Roseburia and Ruminococcus decreased in the non-HE group;and(3)Members from the pathogenic genus Morganella appeared in the HE group but not in the non-HE group.CONCLUSION Intestinal microbiota-related synergism may predict the risk of HE following TIPS placement in patients with HBVrelated PH.Prophylactic microbiome therapies may be useful for preventing and treating HE after TIPS placement.

Organizing pneumonia secondary to pulmonary tuberculosis:A case report

BACKGROUND Organizing pneumonia secondary to pulmonary tuberculosis is rare.Moreover,the temporal boundary between pulmonary tuberculosis and secondary organizing pneumonia has not been defined.We report a case of secondary organizing pneumonia associated with pulmonary tuberculosis occurring after nine months of antituberculosis treatment.CASE SUMMARY A 54 years old man,previously diagnosed with pulmonary tuberculosis and tuberculous pleurisy,underwent nine months of antituberculosis treatment.Follow-up lung computed tomography revealed multiple new subpleural groundglass opacities in both lungs,and a lung biopsy confirmed organizing pneumonia.Treatment continued with anti-tuberculosis agents and hormone therapy,and subsequent dynamic pulmonary computed tomography exams demonstrated improvement in lesion absorption.No disease recurrence was observed after corticosteroid therapy discontinuation.CONCLUSION When treating patients with active pulmonary tuberculosis,if an increase in lesions is observed during anti-tuberculosis treatment,it is necessary to consider the possibility of tuberculosis-related secondary organizing pneumonia,timely lung biopsy is essential for early intervention.

Unveiling the Threat: Case Reports of Extra-Pulmonary Tuberculosis among Sanctuary Chimpanzees

Primate sanctuaries across Africa play a pivotal role in the rescue and rehabilitation of confiscated and rescued wild primates, many of whom have had extensive contact with humans prior to their arrival and throughout the rehabilitation process, heightening the risk of disease transmission. While tuberculosis is not naturally occurring in free-living chimpanzees, it has been extensively observed in captive primates that have been in close proximity to humans or other captive primates infected with Mycobacterium tuberculosis. This case report delves into an outbreak of extra-pulmonary tuberculosis among juvenile chimpanzees within a sanctuary, detailing the associated diagnostic challenges and treatment approaches. The five cases had close contact with a caregiver infected with tuberculosis, subsequently transmitting the infection to other in-contact chimpanzees. Prolonged treatment, employing the human protocol of quadri-therapy (rifampicin, isoniazid, pyrazinamide, and ethambutol), followed by bi-therapy (rifampicin and isoniazid), resulted in complete resolution for all five cases. These cases underscore the critical importance of maintaining high levels of biosecurity, implementing effective quarantine measures, and adhering to strict hygiene practices when working with non-human primates.

Comparative analysis of pulmonary and extrapulmonary tuberculosis:A seven-year experience from a refugee host country,Turkiye

Objective:To investigate and compare the demographic characteristics,clinical findings,and laboratory results of pulmonary tuberculosis(PTB)and extrapulmonary tuberculosis(EPTB)patients,among Turkish citizens,and foreign nationals.Methods:This study included patients aged 18 and over,both Turkish citizens and foreign nationals,diagnosed with PTB or EPTB between 2016 and 2022.All patients were divided into PTB and EPTB group,and demographic characteristics,clinical findings,and laboratory results were compared.Patients with both PTB and EPTB were not included in the comparison.Multivariate logistic regression analysis was conducted to identify potential risk factors for PTB.Results:Among the 261 TB cases included,46 patients(17.6%)had PTB,and 188(72%)had EPTB.The percentage of female patients was significantly higher(P=0.003)in EPTB compared to PTB group.While the prevalence of diabetes mellitus(P=0.002),hypertension(P=0.017),coronary obstructive pulmonary disease(P=0.001),congestive heart failure(P=0.005),coronary artery disease(P=0.001)and immunosuppressive medication use(P=0.017)were significantly higher in PTB patients than in EPTB patients.Multivariate logistical analysis reveals that male(OR 2.6,95%CI 1.3-5.5,P=0.009),diabetes mellitus(OR 2.7,95%CI 1.2-6.1,P=0.015),and asthma(OR 6.3,95%CI 1.2-33.9,P=0.032)were associated with an increased risk of PTB.Social security coverage(P<0.001)and regular employment status(P<0.001)were found to be lower and the presence of multidrug resistance(P=0.002),isoniazid resistance(P=0.012),and rifampin resistance(P=0.012)were found to be significantly higher in foreign-national TB patients comparing with Turkiye citizens.Conclusions:Patients with PTB need to be evaluated for comorbidities and PTB should be investigated in men,in patients with diabetes mellitus or asthma if there are clinical findings suspicious for TB.TB screening for foreign nationals upon entry into the country is essential for TB control and elimination.

From immunology to artificial intelligence: revolutionizing latent tuberculosis infection diagnosis with machine learning

Latent tuberculosis infection(LTBI)has become a major source of active tuberculosis(ATB).Although the tuberculin skin test and interferon-gamma release assay can be used to diagnose LTBI,these methods can only differentiate infected individuals from healthy ones but cannot discriminate between LTBI and ATB.Thus,the diagnosis of LTBI faces many challenges,such as the lack of effective biomarkers from Mycobacterium tuberculosis(MTB)for distinguishing LTBI,the low diagnostic efficacy of biomarkers derived from the human host,and the absence of a gold standard to differentiate between LTBI and ATB.Sputum culture,as the gold standard for diagnosing tuberculosis,is time-consuming and cannot distinguish between ATB and LTBI.In this article,we review the pathogenesis of MTB and the immune mechanisms of the host in LTBI,including the innate and adaptive immune responses,multiple immune evasion mechanisms of MTB,and epigenetic regulation.Based on this knowledge,we summarize the current status and challenges in diagnosing LTBI and present the application of machine learning(ML)in LTBI diagnosis,as well as the advantages and limitations of ML in this context.Finally,we discuss the future development directions of ML applied to LTBI diagnosis.

Recognizing and addressing the challenges of gastrointestinal tuberculosis

In this editorial,we comment on the article by Ali et al published in the recent issue of the World Journal of Clinical Cases.This case report shed light on a particularly rare manifestation of this disease-primary gastrointestinal tuberculosis(GTB)presenting as gastric outlet obstruction.GTB presents diagnostic challenges due to its nonspecific symptoms and lack of highly accurate diagnostic algorithms.This editorial synthesizes epidemiological data,risk factors,pathogenesis,clinical presentations,diagnostic methods,and therapies to raise awareness about GTB.GTB constitutes 1%-3%of all tuberculosis cases globally,with 6%-38%of patients also having pulmonary tuberculosis.Pathogenesis involves various modes of Mycobacterium tuberculosis complex entry into the gastrointestinal system,with the terminal ileum and ileocecal valve commonly affected.Clinical presentation varies,often resembling other intra-abdominal pathologies,necessitating a high index of suspicion.Diagnostic tools include a combination of biochemical,microbiological,radiological,and endoscopic assessments.Antitubercular medication remains the cornerstone of treatment,supplemented by surgical intervention in severe cases.Multidisciplinary management involving gastroenterologists,surgeons,pulmonologists,and infectious disease specialists is crucial for optimal outcomes.Despite advancements,timely diagnosis and management challenges persist,underscoring the need for continued research and collaboration in addressing primary GTB.

Primary extrapulmonary tuberculosis diagnosis warrants extraprecautious pulmonary tuberculosis exclusion workup

This editorial article takes an opportunity to apprehend the diagnostic challenges of primary gastrointestinal tuberculosis(an uncommon extrapulmonary tuberculosis condition)utilizing the recently published case report of a young male with prolonged gastrointestinal symptoms and weight loss who received intermittent anti-tubercular treatment and underwent operative interventions to relieve gastric outlet obstruction.The diagnosis chiefly relied on high-end examinations,like computed tomography scans and histopathological evaluation of postoperatively resected bowel tissue,which wasn't preceded by an all-inclusive stepwise primary pulmonary tuberculosis exclusion approach that usually begins with a detailed tuberculosis-pertinent history acquisition.Given the geographic locations where the patient had been(and/or treated),pivotal consideration of tuberculosis-associated endemicities in those regions,like human immunodeficiency virus(HIV)infection,might have improved the case description.The obtainment of HIV-relevant histories,like intravenous drug use and sexual practice,are good places to start.The sputum bacteriology also seems imperative to rule out atypical Mycobacterium species infection because of its clinico-radiohistopathological resemblance with pulmonary Mycobacterium tuberculosis.Altogether,this editorial aims to underscore that primary extrapulmonary tuberculosis diagnosis should comprise an elaborative,comprehensive,systematic,and stepwise primary pulmonary Mycobacterium tuberculosis exclusion workup.
