Inflammatory pseudotumors present diagnostic difficulties because the clinical and radiological findings tend to suggest a malignancy. The symptoms include weight loss, fever, and abdominal pain. Most cases of splenic IPT present solitary relatively large well circumscribed masses on imaging. The diagnosis in the majority of the cases is made after histopathologic study of splenectomy specimens. The IPTs that occur in the spleen and liver are typically associated with Epstein-Barr virus. Thirtyseven percent of all new cases of active tuberculosis infection are extrapulmonary tuberculosis and tuberculous lymphadenitis the most commonly occurring form of extrapulmonary tuberculosis. We report the case of an inflammatory pseudotumor of the spleen associated with splenic tuberculous lymphadenitis in a 50-year-old female patient who was preoperatively diagnosed with a malignant spleen tumour based on her history of breast of carcinoma.展开更多

METHOD:We report a patient with isolated tuberculosis of the liver and spleen. RESULTS:A 50-year-old man presented with weakness and loss of weight for two months.CT scan of the abdomen showed multiple small hypodense lesions in the liver and spleen.Image-guided biopsy of liver lesion was inconclusive as it showed normal hepatocytes with interspersed lymphocytes.On laparotomy,the liver and spleen were studded with multiple small nodules.A 5-cm wedge of the liver was resected.Histopathological examination confirmed the diagnosis of tubercular hepatitis.A detailed work-up failed to identify any other focus of tuberculosis. CONCLUSION:Although rare,tuberculosis should also be considered in the differential diagnosis for multiple nodules in the liver and spleen,along with lymphoproliferative diseases and metastatic lesions.展开更多

Liver and splenic tuberculosis is a classic disease which represents 1.5% of all gastrointestinal tuberculosis. Patients and Methods: We reported the case of a fifty-six years old patient admitted in the department of surgery for acute cholecystitis, and the biological balance showed a hyperleukocytosis at 16,000 elements/mm3 and a CRP at 25 with a light cholestasis. The abdominal scanner showed a micronodular splenomegaly with coelio mesenteric ganglions. We discovered a tuberculosis location in the liver and the spleen and we realized a cholecystectomy with a hepatic biopsy and a splenectomy. Results: A gallbladder ablation associated with an enlarged spleen and liver biopsy was diagnosed with liver and splenic tuberculosis. The patient was put under anti tubercular treatment with the good clinical and radiological evolution. Conclusion: The diagnosis of tuberculosis should always be considered especially in endemic countries.展开更多

文摘Background:Skeletal tuberculosis(TB)remains a persistent clinical and research chal-lenge due to its chronic course,osteolytic destruction,and the limitations of existing animal models,which often require high-level biosafety containment or fail to repli-cate human skeletal pathology.Methods:This study developed a biosafe,accessible,and versatile murine model of skeletal TB using Mycobacterium smegmatis,a fast-growing,nonpathogenic myco-bacterial species with high genomic homology to Mycobacterium tuberculosis.Three infection routes-subperiosteal calvarial injection,intratibial injection,and intra-cardiac inoculation-were systematically evaluated for their ability to induce lo-calized versus disseminated bone infection under standard biosafety level(BSL)-1 conditions.Results:Subperiosteal calvarial and intratibial injection of M.smegmatis induced local-ized bone lesions characterized by osteolysis,sequestrum formation,granulomatous inflammation,and increased osteoclast activity.Intratibial infection additionally trig-gered compartment-specific immune responses,including neutrophil and macrophage expansion,transient B-cell depletion,and activation of interferon-γ^(+)(IFN-γ^(+))T cells,reflecting active immune remodeling at the infection site.Systemic dissemination via intracardiac injection reproducibly generated progressive vertebral and tibial bone destruction with organized granuloma formation and immune cell infiltration but without prominent sequestrum formation.Compared to intratibial infection,intracar-diac delivery exhibited lower intragroup variability and more closely recapitulated the diffuse progression of extrapulmonary skeletal tuberculosis.Conclusions:This M.smegmatis-based murine model provides a straightforward,reliable,and immunopathologically relevant platform for exploring host-pathogen dynamics,immune-driven bone destruction,and early-stage therapeutic testing in skeletal TB,all within standard BSL-1 laboratories.This model fills a critical gap by enabling BSL-1 research into skeletal TB mechanisms and drug development.

文摘BACKGROUND Tuberculous osteitis is a chronic,granulomatous bone infection that frequently results in impaired bone healing following surgery.Despite surgical intervention and prolonged anti-tuberculous therapy,complete bone regeneration often remains unachieved,contributing to subsequent orthopedic complications.AIM To investigate the efficacy and safety of pamidronate in promoting bone regeneration following surgical treatment of experimental animal tuberculous osteitis.METHODS A controlled randomized basic study of rabbit femoral tuberculosis induced by Mycobacterium tuberculosis strain H37Rv included surgical removal of infected tissue and implantation of osteoinductive bone grafts with the following animal allocation to one of three groups:(1)Bisphosphonates alone;(2)Bisphosphonates combined with anti-tuberculous therapy;and(3)Anti-tuberculous therapy alone.The control group consisted of animals that received no surgical or medical treatment.Clinical evaluations,biochemical markers,micro-computed tomography imaging,and histomorphometry analyses were conducted at 3 months and 6 months postoperatively.RESULTS Pamidronate treatment significantly reduced early implant resorption,increased osteoblastic activity,improved trabecular bone regeneration,and maintained graft integrity compared to the anti-tuberculous therapy-only group.Histologically,pamidronate led to enhanced vascular remodeling and increased bone matrix formation.Crucially,bisphosphonate therapy demonstrated safety,compatibility with anti-tuberculous medications,and did not exacerbate tuberculous inflammation.Furthermore,micro-computed tomography analysis revealed a significant increase in trabecular thickness and density in pamidronate-treated groups,underscoring the anabolic effects of bisphosphonates.Morphometric evaluation confirmed a marked reduction in osteoclast number and activity at graft interfaces.These combined radiological,histological,and biochemical data collectively demonstrate the efficacy of pamidronate as an adjunctive agent in enhancing bone repair outcomes following surgical intervention for tuberculous osteitis.CONCLUSION A single intravenous dose of pamidronate significantly enhances bone regeneration and prevents implant resorption following surgical treatment of tuberculous osteitis.The following prospective studies are needed.

文摘Objective Post tuberculosis lung disease(PTLD)manifests in various forms,including tuberculosisassociated chronic obstructive pulmonary disease(TB-COPD),yet the clinical features of PTLD remain undercharacterized.This study aimed to assess longitudinal changes in lung function over a 5-year period and to identify predictors of airflow obstruction in a cohort of patients treated for active pulmonary TB.Methods Patients with active pulmonary TB were enrolled in this study and were followed during treatment,at treatment completion and five years post-treatment.Assessments included lung function and chest CT,analyzing longitudinal trends and airflow obstruction risk factors.Results Among 53 patients(mean age 36.9±13.9 years;64.2%male),7 patients(13.2%)exhibited airflow obstruction.At the 5-year follow-up,the mean FEV_(1)/FVC declined significantly(76.27%±12.04%vs.80.23%±11.02%,P<0.001)and 9 patients(17.0%)exhibited airflow obstruction.Seven of these patients predominantly showed air trapping consistent with small airway disease on chest CT,aligning with TB-COPD phenotype.Notably,four young-to-middle-aged patients(<60 years old)had persistent obstruction over the five years.Conclusion The initial test revealed that 13.2%of patients presented with airflow obstruction.By the 5-year follow-up,this proportion had increased to 17.0%,with most cases demonstrating imaging findings aligning with TB-COPD,even among younger,non-smoking individuals.These findings emphasize the importance of long-term follow-up and routine lung function assessments in TB survivors.
文摘Detection and treatment of drug resistance in extrapulmonary tuberculosis(EPTB)is a major challenge worldwide.Drug resistance in EPTB has not been studied extensively.However,patients with drug-resistant EPTB have been reported to have poor outcomes[1].Rifampicin and isoniazid are the cornerstone drugs in the management of EPTB.Resistance in Mycobacterium(M.)tuberculosis to these drugs commonly arises due to mutations in the‘rpoB’gene and‘katG&inhA’genes,which confer resistance to rifampicin and isoniazid,respectively.Treatment outcomes are affected by the presence of these mutations.In addition,anatomical and physiological barriers impede the effective delivery of drugs to the affected extrapulmonary site[1].An analysis of the frequency of mutations in drug resistant M.tuberculosis strains causing EPTB in our region can help identify patterns of drug resistance.This,in turn,can provide inputs that may be used for modifying standard treatment regimens to make them more effective.The present study aims to identify the frequency and pattern of mutations in the‘rpoB’gene and‘katG&inhA’genes in M.tuberculosis strains isolated from EPTB samples.
文摘Tuberculosis(TB)remains a critical global health challenge,with 10.8 million new cases and over 1.25 million deaths reported annually,disproportionately affecting low-income regions.Despite its use,the Bacillus Calmette-Guérin(BCG)vaccine provides limited protection against adult pulmonary TB,necessitating novel solutions.The messenger RNA(mRNA)vaccine technology,proven effective in combating coronavirus disease 2019,offers significant promise for TB prevention.These vaccines elicit robust immune responses by encoding antigens that stimulate humoral and cell-mediated immunity,essential for combating mycobacterium TB.Unlike traditional methods,mRNA vaccines are highly adaptable,scalable,and capable of targeting emerging strains.Preclinical studies highlight the enhanced efficacy of mRNA TB vaccines over BCG,demonstrating their ability to reduce bacterial burdens and generate memory T-cell responses critical for long-term protection.However,challenges persist,including mRNA instability,cold-chain storage needs,and mycobacterium’s complex immune evasion strategies.Innovative solutions,such as lipid nanoparticle delivery systems and selfamplifying mRNA platforms,are being developed to address these barriers.The initiation of clinical trials,notably BioNTech’s BNT164,marks a pivotal advancement in TB vaccine development.These trials focus on safety,immuno genicity,and efficacy,particularly in regions with high TB prevalence.While logistical and financial hurdles remain,mRNA vaccines hold transformative potential to bridge critical gaps in TB prevention.Their adaptability extends to tackling co-infections like human immunodeficiency virus,further amplifying their impact on global health.By integrating mRNA vaccines into existing TB control strategies,these advancements could revolutionize prevention efforts,especially in regions where current solutions fall short.Continued innovation and investment are crucial to harnessing the full potential of mRNA vaccines,positioning them as a cornerstone in the fight against TB and its global eradication.

文摘BACKGROUND Tuberculosis is among the most devastating infectious diseases worldwide.Spinal tuberculosis is not easy to detect at an early stage,which without effective treatment often leads to spinal deformity and spinal cord damage which in turn cause complications such as paraplegia and quadriplegia.In this study,we established a model using three concentrations of bacteria and carried out a comprehensive evaluation of the model by imaging,general observations,and histopathological and bacteriological studies.AIM To establish a rabbit model of spinal tuberculosis and examine the effect on the model’s efficacy using different concentrations of Mycobacterium tuberculosis(M.tuberculosis)inoculum.METHODS New Zealand rabbits were randomly divided into experimental,control and blank groups.The experimental and control animals were sensitized with complete Freund′s adjuvant,a hole was drilled beneath the upper endplate of the L6 vertebral body and filled with gelfoam sponge.The experimental group was divided into three subgroups(experimental 1,experimental 2,experimental 3)and infused with M.tuberculosis suspension at various concentrations.The control group was inoculated with saline and the blank group received no treatment.The 12-week post-operative survival rates were 100%,80%and 30%in the experimental groups inoculated with concentrations of 106,107 and 108 CFU/mL bacteria,respectively.RESULTS The survival rate of the control and blank groups was 100%.Vertebral body destruction at 8 weeks in the three experimental groups as determined by X-ray analysis was 33.3%,62.5%and 66.7%,and by computed tomography(CT)and 3-dimensional CT 44.4%,75%and 100%,respectively.At 12 weeks,the figures were 44.4%,75%and 100%by X-ray analysis and 44.4%,100%and 100%by CT and 3-dimensional CT,respectively.All surviving rabbits of the experimental groups had vertebral destruction.The positive bacterial culture rates were 22.2%,75%and 66.7%,respectively,in the experimental groups.After being sensitized with complete Freund's adjuvant,large differences were observed in the extent of spinal tuberculosis after inoculation of the rabbits with different concentrations of H37RV standard M.tuberculosis.CONCLUSION The experimental 1 had a low success rate at establishing an infection.The experimental 3 resulted in high mortality and complication rates.The experimental 2 was optimum for establishing a spinal tuberculosis model based on the high level of symptoms observed and the low rabbit mortality.
文摘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.
文摘Chronic obstructive pulmonary disease(COPD)and respiratory tuberculosis are important respiratory problems.Meeting together,these diseases can mutually worsen the severity of clinical manifestations and negatively affect prognosis.COPD and tuberculosis share a number of common risk factors and pathogenetic mechanisms involving various immune and non-immune cells.Inflammation,hypoxia,oxidative stress,and lung tissue remodeling play an important role in the comorbid course of COPD and respiratory tuberculosis.These mechanisms are of diagnostic interest and are promising therapeutic targets.Thus,the aim of the current review is to discuss the mechanisms of the comorbid course of chronic obstructive pulmonary disease and respiratory tuberculosis.
文摘There is a lack of consensus on the optimal surgical approach for splenic flexure malignancies.Surgeons face the challenge of balancing successful oncological outcomes with the morbidity and functional effects of extended colonic resection,considering the variable‘watershed’vasculature and lymphatic anatomy of the splenic flexure.While there is an increasing body of evidence supporting the oncological safety of a more conservative segmental resection,most of the data stems from retrospective single center studies.This article reviews the management strategies and examines the evidence supporting various surgical approaches to splenic flexure malignancies.
文摘BACKGROUND Due to low bacteria count and high likelihood of having extrapulmonary tuberculosis(TB)among patients with advanced human immunodeficiency virus(HIV)disease,the World Health Organization(WHO)recommended the use of urine lateral flow urine lipoarabinomannan(LF-LAM)or sputum-Xpert to screen for TB.AIM To estimate pooled prevalence of TB screening uptake,TB diagnosis,TB treatment initiation and mortality among patients with advanced HIV disease in Africa.METHODS PubMed,Cochrane Library and EMBASE were searched for articles published between January 2011 and December 2024.TB screening uptake was defined as percentage of patients with advanced HIV disease(CD4≤200 cells/mm3 or WHO stage III/IV)who tested for TB.Using random effects models,we computed the pooled estimate of TB screening uptake,TB prevalence,TB treatment initiation and mortality and their corresponding 95%CIs.Stratified analysis to compare uptake of TB testing and TB prevalence between children vs adults and multisite vs single site studies was performed.RESULTS A total of nineteen studies with 16065 people with advanced HIV disease were analyzed.The pooled prevalence of TB screening uptake was 64.6%(95%CI:49.2–80.1).The pooled prevalence of TB was 29.4%(95%CI:22.0–36.8),and TB treatment initiation was 77.9%(95%CI:63.9–91.8),and mortality was 19.5%(95%CI:8.9–30.0).The pooled prevalence of TB testing uptake was significantly lower among children compared to adults(28.2%vs 66.4%,P=0.003)and lower for multi-sites compared to single site studies(58.8%vs 82.9%,P=0.002).The pooled prevalence of TB was significantly lower among children compared to adults(24.2%vs 27.6%,P=0.012)and higher among studies that involved multi vs single sites(30.0%vs 21.9%,P=0.001).CONCLUSION Four in ten people with advanced HIV disease were not screened for TB as recommended by the WHO,indicating significant gaps in identifying patients with TB.Excluding patients with evidence of TB is critical to avoid exposing them to subtherapeutic levels of anti TB treatment.
文摘Objective:To identify factors associated with hepatotoxicity during the intensive phase of treatment in tuberculosis(TB)patients.Methods:A case-control study was conducted of TB patients treated with first-line anti-TB drugs from 2013 to 2020.Cases were defined as patients who developed hepatotoxicity,while controls were those without hepatotoxicity,at a 1:2 ratio.Controls were randomly selected from the same hospitals as the cases.The primary outcome was the occurrence of hepatotoxicity during the intensive treatment phase,with data retrospectively collected from medical records.Descriptive statistics and multiple logistic regression with backward elimination were used for analysis.Results:Among 3021 tuberculosis patients who received first-line anti-tuberculosis regimen,50 had abnormal liver function and 14 developed hepatotoxictiy.In addition,2957 patients had normal liver function and 128 served as controls for this analysis.Multiple logistic regression analysis revealed that female patients had about twice the risk of hepatotoxicity compared to males(adjusted OR 2.25,95%CI 1.11-4.59),and patients with HIV coinfection were nearly 10 times more likely to develop hepatotoxicity than those without HIV(adjusted OR 9.74,95%CI 3.12-30.41).Conclusions:Female sex and HIV coinfection were found to be significant risk factors for hepatotoxicity during the intensive phase of TB treatment.Enhanced monitoring and preventive strategies are recommended for these high-risk groups to reduce the risk of hepatotoxicity.
文摘BACKGROUND Pancreatic tuberculosis(TB)is a rare clinical condition that is frequently misdia-gnosed.A definitive diagnosis is often established through surgical biopsy.CASE SUMMARY We report a previously healthy 21-year-old male who presented with epigastric pain and fever.Initially diagnosed with a pancreatic abscess and duodenal bulb perforation,the patient declined surgical intervention and was subsequently re-ferred to our hospital.Abdominal computed tomography and endoscopy revea-led a duodenal bulb perforation,esophageal and duodenal ulcers,and a mass in the pancreatic head.Endoscopic ultrasound with fine-needle aspiration identified a hypoechoic mass suggestive of TB.Cytological and histopathological analysis confirmed the diagnosis.The patient was diagnosed with primary pancreatic TB and started on anti-TB therapy.At the 1-year follow-up,the pancreatic mass had markedly regressed,and the patient had fully recovered with complete symptom resolution.CONCLUSION Pancreatic TB should be included in differential diagnosis;prompt endoscopic ul-trasound-fine-needle aspiration and therapy enable recovery.
