RESUMEN
BACKGROUND: Cell subsets differentially modulate host immune responses to Mycobacterium tuberculosis (MTB) infection. However, the nature and functions of these subsets against osteoarticular tuberculosis (OTB) are unclear. Here, we aimed to understand the phenotypes and functions of immune cell subsets in patients with OTB using single-cell RNA sequencing (scRNA-Seq). METHODS: Pathological and healthy adjacent tissues were isolated from patients with OTB and subjected to scRNA-Seq. Unsupervised clustering of cells was performed based on gene expression profiles, and uniform manifold approximation and projection was used for clustering visualization. RESULTS: Thirteen cell subsets were identified in OTB tissues. scRNA-seq datasets of patients and healthy controls (HCs) showed that infection changed the frequency of immune cell subsets in OTB tissues. Myeloid cell examination revealed nine subsets. The frequency of macrophage-RGS1high subsets decreased in OTB tissues; this increased MTB susceptibility in an SLC7A11/ferroptosis-dependent manner. Immunohistochemistry assays and flow cytometry for patients with OTB and osteoarticular bacterial infection (OBI) and HCs verified that the frequency of macrophage-RGS1high subset decreased in OTB tissues and blood samples, thereby distinguishing patients with OTB from HCs and patients with OBI. CONCLUSION: The macrophage-RGS1high subset levels were decreased in patients with OTB, and would be up-regulated after effective treatment. Therefore, the clinical significance of this study is to discover that macrophage-RGS1high subset may serve as a potential biomarker for OTB diagnosis and treatment efficacy monitoring.

Tuberculosis is a preventable and generally curable infectious disease caused by Mycobacterium tuberculosis. It mostly affects the lungs causing pulmonary tuberculosis; however, it may also involve non-pulmonary organs resulting in extrapulmonary tuberculosis (EPTB). Diagnosis of tuberculosis was based on the constitutional symptoms, organ-specific radiographs, and biological specimen examination. However, diagnosis of extrapulmonary tuberculosis can be difficult when the lungs are not affected and constitutional signs and symptoms of tuberculosis that can help to identify the disease are absent. Although multi-drug-resistant extrapulmonary tuberculosis is not uncommon, primary drug-resistant extrapulmonary tuberculosis in certain areas such as the extraspinal osteoarticular joint, tympanic membrane, and central nervous system is still rare. In this piece, we present three cases of primary multidrug-resistant extrapulmonary tuberculosis with an unusual presentation.

Tuberculosis is one of the oldest known diseases and it remains one of the main causes of morbidity and mortality, especially in developing countries. It is associated with social inequalities and affects different age groups. Tuberculosis in children and adolescents should be considered a sentinel event, since it is linked to a recent infection through contact with bacilliferous adults. We report an immunocompetent 15-year-old adolescent with tuberculosis, exhibiting pulmonary, osteoarticular, and cutaneous involvement. Conventional treatment with tuberculostatic drugs for a year had satisfactory results without sequelae.

CONTEXT AND AIMS: Tuberculosis (TB) is a leading cause of infectious disease deaths in India. It is also one of the most challenging diseases to diagnose and treat effectively. TB can occur both in the lungs and in extrapulmonary locations through hematogenous spread. Osteoarticular TB is a type of extrapulmonary characterized by atypical presentation. If diagnosed early, it can be treated effectively with reduced risk of mortality. SUBJECTS AND METHODS: At Nalanda medical college and hospital, an 18-month prospective research was undertaken. The study included a total of 120 patients with osteoarticular TB. Serum electrophoresis of blood samples was performed at baseline, 2 months, and 4 months following antitubercular medication administration. The fractions of albumin, α1, α2, ß, and γ globulins were estimated and compared with the baseline value. RESULTS: It was observed that as the disease progressed and became more chronic, there was a decrease in albumin and an increase in α1, α2, ß, and γ globulin percentages of serum proteins. Upon follow-up, the serum electrophoresis revealed that these values observed during baseline could be reversed by the administration of antitubercular drugs. CONCLUSIONS: This study suggests that analyzing serum protein fractions could be a cost-effective strategy to determine the presence of osteoarticular TB and also aid in initiating antitubercular treatment.
RésuméContexte et objectifs: La tuberculose (TB) est l'une des principales causes de décès par maladies infectieuses en Inde. C'est également l'une des maladies les plus difficiles à diagnostiquer et à traiter efficacement. La tuberculose peut survenir à la fois dans les poumons et dans des localisations extrapulmonaires par propagation hématogène. La tuberculose ostéoarticulaire est un type de tuberculose extrapulmonaire caractérisée par une présentation atypique. Si elle est diagnostiquée tôt, elle peut être traitée efficacement avec un risque de mortalité réduit. Sujets et méthodes: À la faculté de médecine et à l'hôpital de Nalanda, une recherche prospective de 18 mois a été entreprise. L'étude a inclus un total de 120 patients atteints de tuberculose ostéoarticulaire. L'électrophorèse sérique des échantillons de sang a été réalisée au départ, 2 mois et 4 mois après l'administration de médicaments antituberculeux. Les fractions d'albumine, a1, a2, b et g globulines ont été estimées et comparées à la valeur de base. Résultats: Il a été observé qu'à mesure que la maladie progressait et devenait plus chronique, il y avait une diminution de l'albumine et une augmentation des pourcentages de globulines a1, a2, b et g des protéines sériques. Lors du suivi, l'électrophorèse sérique a révélé que ces valeurs observées au départ pouvaient être inversées par l'administration de médicaments antituberculeux. Conclusions : Cette étude suggère que l'analyse des fractions protéiques sériques pourrait constituer une stratégie rentable pour déterminer la présence d'une tuberculose ostéoarticulaire et également faciliter l'initiation d'un traitement antituberculeux.

RATIONALE: Tuberculosis of the long tubular bones in children's extremities is infrequent, particularly in the ulna. Early diagnosis poses significant challenges. This report presents a case involving a 2-year-old child with tuberculosis of the ulnar bone, accompanied by a comprehensive review of pertinent literature. The purpose of this study is to share diagnostic and therapeutic experiences and provide potentially valuable insights. PATIENT CONCERNS: In this case, the patient exhibited complete destruction and expansion of the ulnar bone, resulting in a forearm size considerably greater than normal. Concerns were raised about the irreversible deformation of the ulna, the potential for a malignant bone tumor, and its impact on forearm function, potentially endangering the patient's life. DIAGNOSES: The diagnosis was confirmed as tuberculosis of the ulnar bone. INTERVENTIONS: The patient underwent surgery to remove the affected ulnar tissue and received anti-tuberculosis medication. OUTCOMES: Subsequent to treatment, the destruction and expansion of the ulnar bone resolved, with the return of normal ulnar morphology and bone structure. LESSONS: Even in the absence of typical symptoms like fever, weight loss, and loss of appetite, extensive destruction and expansion of a long tubular bone should prompt vigilant consideration of bone tuberculosis.

CASE: A 65-year-old female patient presented with complaints of diffuse pain and swelling in her right wrist with paresthesia in her right hand with thenar wasting. Her magnetic resonance imaging scan was suggestive of flexor tenosynovitis of the wrist with compression of the median nerve with multiple rice bodies. She underwent excisional biopsy along with median nerve decompression. Mycobacterium tuberculosis was detected by polymerase chain reaction (GeneXpert), and histopathology identified caseous granulomas. The patient was started on antitubercular chemotherapy postoperatively. CONCLUSION: In endemic countries such as India, tuberculous flexor tenosynovitis must always be a differential diagnosis in cases of wrist swelling with rice bodies.

OBJECTIVES: Adenosine deaminase (ADA) activity has shown good performance in diagnosing pleural, peritoneal, and meningeal tuberculosis. This meta-analysis aimed to evaluate the performance of measuring ADA activity in synovial fluid for the early diagnosis of joint tuberculosis. METHODS: We searched published information in MEDLINE, Embase, Cochrane Library, Web of Science, and MedRxiv databases, as well as unpublished information in the American College of Rheumatology and European League Against Rheumatism for conference abstracts (2012-2021). We also scanned the reference lists of articles. Two reviewers independently applied the criteria for selection, assessed quality, and extracted data (PROSPERO number CRD42021284472). RESULTS: Seven independent studies (N=305 subjects) that compared ADA activity in synovial fluid with a composite reference diagnostic method for tuberculosis were included. Overall, the risk of bias was judged low. Studies were classified as high quality (n=3; 148 subjects) and low quality (n=4; 157 subjects). Pooled sensitivity and specificity of ADA activity was 94% (95% confidence interval [CI], 0.89-98; I2=23%) and 88% (95% CI, 83-92; I2=83%), respectively. The random-effects model for pooled diagnostic Odds ratio was 67.1 (95%CI, 20.3-222.2; I2=30%). The receiver operating characteristic curve area was 0.96 (95% CI, 0.92-0.99). Meta-regression did not identify the quality of the study, country of publication, or the type of assay as a source of heterogeneity. CONCLUSIONS: Measuring ADA activity in synovial fluid demonstrates good performance for the early diagnosis of joint tuberculosis.

In the United States, rates of Mycobacterium tuberculosis infection have been declining for decades. Osteoarticular tuberculosis of the ankle is rarely observed. We present the case of a 65-year-old man who immigrated to the United States from India 24 years before the onset of symptoms. The patient initially reported atraumatic swelling and pain of the left ankle and foot and was treated for venous insufficiency. Later, the patient was referred to a nonsurgical orthopaedic clinic for additional workup and was found to have elevated inflammatory markers. MRI showed septic arthritis and osteomyelitis of the talus, distal tibia, and calcaneus. Joint aspiration revealed elevated white blood cell counts with predominately PMNs. The patient was then referred to an orthopaedic foot and ankle surgeon and underwent extensive irrigation and débridement. The patient was discharged on empiric antibiotics. Culture results from the original joint aspirate returned 14 days after surgery as positive for acid-fast bacillus, later identified as M tuberculosis by sequencing. Empiric antibiotics were discontinued, and the patient was started on appropriate antituberculotic therapy. This case report illustrates the challenge in the diagnosis of skeletal tuberculosis and the importance of including this condition on the differential for patients with atypical foot and ankle presentations.

Objective: To analyze the short-term and long-term efficacy of Osteoset artificial bone graft fusion mixed with rifampicin for injection in the treatment of sacroiliac joint tuberculosis. Methods: A retrospective analysis was carried out on 70 patients diagnosed with sacroiliac joint tuberculosis who were admitted and underwent surgical treatment in our orthopedics department between April 2014 and May 2020. The patients were divided into three groups based on the different bone graft materials used: autogenous bone graft group (25 cases), simple lesion removal group (18 cases), and drug-loaded calcium sulfate bone graft group (27 cases). General information and surgical details of the three groups were compared. Sacroiliac X-ray and CT scans were performed at regular intervals to record pre- and post-treatment erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) levels, bone graft fusion rates at 6, 12, and 18 months post-surgery, Majeed score for functional evaluation, and postoperative complications. Results: There was no statistically significant difference in operation time, intraoperative bleeding, and intraoperative pus removal volume among the three groups of patients (P > .05). Postoperatively, 70 patients were followed up, and the serum levels of ESR and CRP in all three groups of patients were significantly reduced at 3 months after surgery (P < .05). In the autogenous bone graft group, the bone graft fusion rates were 24.00% (6/25) at 6 months postoperatively, 76.00% (18/25) at 12 months, and 96.00% (24/25) at 18 months. In the simple lesion removal group, the bone graft fusion rates were 16.67% (3/18) at 6 months postoperatively, 27.78% (5/18) at 12 months, and 55.56% (10/18) at 18 months. In the drug-loaded calcium sulfate bone graft group, the bone graft fusion rates were 18.52% (5/27) at 6 months postoperatively, 55.56% (15/27) at 12 months, and 81.48% (22/27) at 18 months. In the autogenous bone graft group, the postoperative Majeed score averaged (91.47±4.13) points, with 13 cases rated as excellent and 10 cases rated as good, resulting in an excellent and good rate of 92.00% (23/25). The Majeed scores at 6, 12, and 18 months postoperatively were (67.19±4.22) points, (80.28±5.83) points, and (91.47±4.13) points, respectively. Among them, there were 4 excellent and 3 good cases at 6 months postoperatively, with an excellent and good rate of 28.00% (7/25). At 12 months postoperatively, there were 8 excellent and 10 good cases, with an excellent and good rate of 72.00% (18/25). At 18 months postoperatively, there were 13 excellent and 10 good cases, with an excellent and good rate of 92.00% (23/25). In the simple lesion removal group, the Majeed scores at 6, 12, and 18 months postoperatively were (59.17±3.95) points, (69.84±5.16) points, and (76.22±8.76) points, respectively. There were 2 excellent and 2 good cases at 6 months postoperatively, with an excellent and good rate of 22.22% (4/18). At 12 months postoperatively, there were 4 excellent and 3 good cases, with an excellent and good rate of 38.89% (7/18). At 18 months postoperatively, there were 5 excellent and 5 good cases, with an excellent and good rate of 55.56% (10/18). In the drug-loaded calcium sulfate bone graft group, the Majeed scores at 6, 12, and 18 months postoperatively were (63.24±4.17) points, (77.39±5.50) points, and (86.64±7.03) points, respectively. There were 3 excellent and 3 good cases at 6 months postoperatively, with an excellent and good rate of 22.22% (6/27). At 12 months postoperatively, there were 9 excellent and 7 good cases, with an excellent and good rate of 59.26% (16/27). At 18 months postoperatively, there were 10 excellent and 12 good cases, with an excellent and good rate of 81.48% (22/27). The Majeed scores for all three groups of patients showed a significant increase in the three follow-up evaluations compared to pre-treatment (P < .05). Conclusion: Drug-loaded Osteoset artificial bone graft fusion is a safe and effective method for treating bone defects after the debridement of sacroiliac joint tuberculosis lesions. It has fewer postoperative complications and achieves bone graft fusion in a shorter time compared to simple lesion removal methods.

CASE: We report a case in the United States of a 12-year-old girl with multidrug-resistant tuberculous (MDR-TB) osteomyelitis of the hand managed with surgical debridement and second-line anti-TB therapy. The disease course was complicated by dissemination and multifocal progression. CONCLUSION: Despite early intervention, multidrug resistance makes TB treatment challenging and facilitated progression to disseminated disease in this case. We review the difficulties in diagnosis and treatment of pediatric MDR-TB.

SETTING: Diagnosing osteoarticular tuberculosis (OATB) and detecting drug resistance is a challenge in an endemic country like India. OBJECTIVE: Truenat MTB Plus assay (TruPlus), a chip-based portable machine, was compared with GeneXpert Ultra (GxUltra) for diagnosing drug-resistant OATB. DESIGN: 115 synovial fluid and pus specimens [22 culture-positive confirmed, 58 culture-negative clinically-suspected, 35 non-TB controls] processed between 2017 and 2023 were subjected to TruPlus, GxUltra and multiplex-PCR for diagnosing OATB. They were further screened for rifampicin resistance using TruRif chip. The performance was evaluated against composite reference standard, phenotypic drug susceptibility testing and rpoB gene sequencing. RESULTS: TruPlus, GxUltra and MPCR detected 77.5 %, 71.25 %, and 83.75 %, cases of OATB, respectively. TruPlus detected five additional cases missed by GxUltra. The performance of TruPlus was comparable to GxUltra (p = 0.074) and to MPCR (p = 0.074), while performance of GxUltra was significantly inferior to MPCR (p = 0.004). The overall agreement with reference standard was substantial for TruPlus and MPCR and moderate for GxUltra. Both TruRif and GxUltra reported 4 cases as rifampicin resistant. CONCLUSION: TruPlus along with TruRif offers better sensitivity than GxUltra. Its compact and portable platform allows wider application in peripheral settings, thus making it a pragmatic solution for diagnosing OATB and its drug resistance.

The incidence of tuberculosis in developed countries has decreased over the years due to the use of effective tuberculosis drugs and improvements in socio-economic conditions. However, with the ease of global transport and increased travel to countries with high tuberculosis prevalence, the reduction in extrapulmonary tuberculosis cases has been less significant compared with the overall decrease in tuberculosis cases. Extrapulmonary tuberculosis can manifest in a variety of ways. Tuberculous dactylitis, a rare form of tuberculous osteomyelitis, was first described by Rankin in 1886. It mainly affects the short tubular bones in the hands and feet of children and is sometimes called 'spina ventosa'. A 42-year-old male patient initially presented to an external centre reporting swelling and pain in the hand joints of one year's duration. Despite one year of treatment with leflunomide and methylprednisolone (16 mg) and a history of methotrexate use during this period, he experienced no improvement. The patient's condition worsened after the start of sulfasalazine. Dermatological examination was performed due to the presence of haemorrhagic crusted papules and plaques on the ventral surface of both hands. A wound culture was taken, but no bacterial growth was observed. One week after the initial evaluation, the patient complained of persistent foul-smelling nasal discharge, which led to an evaluation by the infectious disease department. At this time, the Quantiferon test was positive. Mycobacterial culture on Days 1 and 3 showed growth of the Mycobacterium tuberculosis complex.

Tuberculosis (TB) is a bacterial infection that is well-known in the palaeopathological record because it can affect the skeleton and consequently leaves readily identifiable macroscopic alterations. Palaeopathological case studies provide invaluable information about the spatio-temporal distribution of TB in the past. This is true for those archaeological periods and geographical regions from when and where no or very few TB cases have been published until now-as in the Sarmatian period (1st-5th centuries CE) in the Barbaricum of the Carpathian Basin. The aim of our paper is to discuss five newly discovered TB cases (HK199, HK201, HK225, HK253, and HK309) from the Sarmatian-period archaeological site of Hódmezovásárhely-Kenyere-ér, Bereczki-tanya (Csongrád-Csanád county, Hungary). Detailed macromorphological evaluation of the skeletons focused on the detection of bony changes likely associated with different forms of TB. In all five cases, the presence of endocranial alterations (especially TB-specific granular impressions) suggests that these individuals suffered from TB meningitis. Furthermore, the skeletal lesions observed in the spine and both hip joints of HK225 indicate that this juvenile also had multifocal osteoarticular TB. Thanks to the discovery of HK199, HK201, HK225, HK253, and HK309, the number of TB cases known from the Sarmatian-period Carpathian Basin doubled, implying that the disease was likely more frequent in the Barbaricum than previously thought. Without the application of granular impressions, the diagnosis of TB could not have been established in these five cases. Thus, the identification of TB in these individuals highlights the importance of diagnostics development, especially the refinement of diagnostic criteria. Based on the above, the systematic macromorphological (re-)evaluation of osteoarchaeological series from the Sarmatian-period Carpathian Basin would be advantageous to provide a more accurate picture of how TB may have impacted the ancestral human communities of the Barbaricum.

PURPOSE: Foot tuberculosis is a rare form of osteoarticular tuberculosis, accounting for less than 1% of cases. It presents unique diagnostic challenges due to its nonspecific clinical features and overlapping symptoms with other conditions. This study aimed to investigate the clinical presentation, radiographic findings, and prognosis of foot tuberculosis, with the goal of improving early recognition and appropriate intervention. METHODS: A prospective study was conducted between November 2016 and July 2021, involving 39 patients diagnosed with foot tuberculosis. Clinical examinations, laboratory tests, X-rays, and MRI evaluations were performed to aid in the diagnosis. Biopsy was conducted on patients with radiological lesions. Patients were treated with an 18-month course of antitubercular therapy (ATT). Foot Function Index (FFI) scores were recorded before and after treatment. Statistical analysis was conducted to assess factors impacting prognosis. RESULTS: Unilateral foot involvement was observed in all patients, with a male predominance (61.5%) and a mean age of 31.3 years. The most common symptoms were pain and edema, with sinus tracts present in 17.9% of patients. Radiographic findings showed cystic and sclerotic lesions, with the "spina ventosa" appearance primarily affecting the metatarsal bones. MRI played a valuable role in early detection. Histopathological examination confirmed tuberculosis in all cases, and acid-fast bacilli were found in 23% of patients. Most patients (79.4%) responded well to ATT without requiring surgery. Factors such as high initial ESR, delayed ATT initiation, multiple lesions, and tarsal involvement were associated with unfavourable outcomes. CONCLUSION: Foot tuberculosis presents with nonspecific symptoms, leading to misdiagnosis and delays in appropriate treatment. Clinical examination, radiographic evaluation, and biopsy are essential for accurate diagnosis. Early initiation of ATT is crucial for favourable outcomes. Factors such as high initial ESR, delayed treatment initiation, multiple lesions, and tarsal involvement negatively impact prognosis. This study highlights the importance of recognizing foot tuberculosis and provides insights into its clinical presentation, radiographic features, and treatment outcomes, facilitating timely intervention and improved patient management.

Tuberculosis (TB) is a major cause of morbidity and mortality, representing a challenge for health-care providers worldwide. Extraspinal osteoarticular tuberculosis (ESOTB) represents a rare location of TB. We aim to describe ESOTB focusing on clinical, diagnostic, and therapeutic characteristics of this entity. We report a retrospective case series of patients diagnosed with ESOTB, treated, and followed up between 2015 and 2022. The diagnosis was based either on bacteriological results (culture and polymerase chain reaction [PCR]) or histological analysis. Five patients with confirmed ESOTB, three women and two men, with a mean age of 46.4 (16-72), were enrolled in study. The affected sites were the elbow (one case), the shoulder (one case), the greater trochanter (one case), the second metatarsal (one case), and the distal interphalangeal joint (one case). The mean delay to diagnosis was 5.8 months (3-10)]. The most common symptoms on presentation were pain (all cases), swelling (all cases), and limited joint range of motion (all cases). One case presented with a draining sinus (20%). Radiological findings were soft tissue swelling (two cases) and periarticular bone destruction (all cases). Four patients presented with pathognomonic histology. PCR was performed in two patients and was positive in both of them. All cases were cured after 9-12 months of oral TB treatment without relapse for the 12-18 months of follow-up. Only one patient underwent surgery for abscess drainage to gain local infection control. ESOTB is a mysterious condition that must not be overlooked and should be suspected in cases of long-standing bone and joint pain and swelling.

Tuberculosis (TB) affecting calcaneum is relatively rare in immunocompetent adults. Due to its nonspecific presentation and the absence of constitutional symptoms of TB, diagnosis is often delayed. The authors present a case of TB of calcaneum in a young male. A 20-year-old male presented with persistent pain and mild swelling of the right heel for 6 months. Upon evaluation with radiographs, a lytic lesion was noted in the posteromedial aspect of the right calcaneum. Magnetic resonance imaging was done and was reported as subacute osteomyelitis with Brodie's abscess. An open biopsy was performed and the obtained tissue was sent for histopathological examination. Histopathology showed features suggestive of Koch's etiology. All the microbiological investigations, including polymerase chain reaction for TB were negative. The patient was started on antitubercular therapy (ATT) based on weight. After 4 months of ATT, the patient developed multiple discharging sinuses over a previous open biopsy scar for which repeat debridement was done. After 12 months of ATT, the patient was asymptomatic, and radiologically, the lesion was healed. Early diagnosis and treatment with ATT will prevent massive destruction and collapse of the calcaneal body and further spread into the subtalar joint. Repeated debridements may be needed in case of nonhealing discharging sinuses to decrease the local infection load.
