Bacille Calmette-Guérin Vaccine-Induced Tuberculous Elbow Osteomyelitis in an Infant: A Case Report.

CASE: We report a case of Bacillus Calmette-Guérin (BCG) vaccine-induced osteomyelitis of the distal end of the right humerus in a 1-year and 8-month-old girl. The patient was treated with debridement and a 12-month antituberculosis drug. After 3 years of follow-up, no growth disturbances or sequelae were observed. CONCLUSION: BCG osteomyelitis is difficult to diagnose because of its rarity. It is important to suspect BCG osteomyelitis based on symptoms and blood tests and to perform PCR testing. Long-term follow-up after treatment is necessary to monitor for recurrence and avoid growth disturbances until epiphyseal line closure occurs.

Multifocal osteoarticular tuberculosis in a systemic lupus erythematosus (SLE) patient: a rarity or an underdiagnosed condition?

Tuberculosis (TB) and its association with rheumatic diseases have been widely recognised. Occurrence of multifocal skeletal involvement constitutes <5% of all skeletal TB cases. We present a Malay patient with multifocal osteoarticular TB (OATB). A 35 year-old SLE woman with background usage of corticosteroid therapy and Azathioprine presented with lupus nephritis flare. Renal biopsy revealed diffuse proliferative lupus nephritis and intravenous (IV) Cyclophosphamide 0.5 g/m2 (850 mg) was initiated. One week later, patient complained dorsum of left hand and right knee swelling. On physical examination, patient was afebrile and the left hand swelling was cystic in consistency while right knee was warm and tender. Erythrocyte Sedimentation Rate (ESR) was 50 mm/hr and C-Reactive Protein (CRP) was 9.4 mg/L. Her Mantoux test was positive with 20 mm induration. Wrist radiograph and chest radiograph was normal. Musculoskeletal ultrasound showed 4th extensor compartment tenosynovitis with Doppler signal and right knee effusion with synovial proliferation. Extensor tenosynovectomy and right knee aspiration was performed. Left hand excised tissue and right knee synovial fluid for acid-fast bacilli (AFB) stain, TB PCR, bacterial and fungal cultures were negative. Urgent histopathological examination of the excised tissue showed necrotising granulomatous inflammation. Patient was empirically started on TB treatment and subsequent mycobacterial culture confirmed the diagnosis of TB. The joints swelling resolved after one month of TB treatment. Multifocal OATB is an infrequent form of extrapulmonary TB and diagnosing OATB requires high index of suspicion particularly in SLE patient on immunosuppression. Prompt investigations are essential to the diagnosis of this rare condition for early initiation of anti-tuberculous therapy.

Tuberculosis osteomyelitis in an old fused hip; activated by prednisolone, salazosulfapyridine, and low-dose methotrexate therapy in a patient with rheumatoid arthritis.

Osteoarticular tuberculosis can occur in patients with rheumatoid arthritis (RA) receiving immunosuppressive therapy. Here, we describe a case of tubercular osteomyelitis in an old fused hip of a patient with RA who received prednisolone, salazosulfapyridine (SASP), and low-dose methotrexate (MTX). A 77-year-old man with a 4-year history of RA was admitted with a complaint of general fatigue. His symptoms of RA had been well controlled with a combination of prednisolone, SASP, and low-dose MTX. Because the laboratory data showed an increase in serum C-reactive protein levels, we suspected pneumonia. There was expansion of a pre-existing consolidation in the right lower lobe of his lung on chest computed tomography, and the sputum culture was positive for Klebsiella oxytoca. His family physician prescribed empiric antibiotics for pneumonia. Although the QuantiFERON® test result was positive, the acid-fast bacillus staining result was negative in the sputum. He started complaining of pain in his left hip, where arthrodesis was performed for an unknown reason at the age of 20 years. Sonographic examination of his left thigh revealed fluid collection. The aspiration culture of the fluid was positive for Mycobacterium tuberculosis. He was initiated on rifampicin, isoniazid, pyrazinamide, and ethambutol. Surgical debridement of the fused left hip was performed twice along with a removal of previously implanted materials. Although infrequent, osteoarticular tuberculosis can occur during immunosuppressive therapy, especially in elderly patients. Physicians should be aware of a history of possible tuberculosis infection, such as hip arthrodesis, when prescribing MTX along with SASP and corticosteroid in the elderly.

BCGitis of the wrist after intravesical BCG therapy: A case report.

Septic arthritis of the wrist can result in joint destruction, making timely diagnosis crucial for initiating empiric antibiotics and surgical intervention. Mycobacterium is a rare cause of this disorder. A 47-year-old man with bladder cancer was treated surgically and received BCG intravesical therapy. Eleven months later, this patient developed severe carpal BCGitis requiring total carpal resection. The first step was addition of a cement spacer and radiometacarpal stabilisation (Masquelet technique). Secondary infections occurred aggravating the prognosis. This case emphasises the importance of taking into account the patient's medical history. Tuberculosis of the wrist is a rare etiology for septic arthritis; delayed treatment leads to severe complications and functional sequelae.

Epidemiology of skeletal tuberculosis in Beijing, China: a 10-year retrospective analysis of data.

Skeletal tuberculosis (STB) is one of the most common forms of extrapulmonary tuberculosis; however, limited epidemiological data are available on this public health concern worldwide, especially in developing countries. The aims of this study were to analyze the epidemiological characteristics of STB cases and to identify risk factors associated with drug resistance among STB cases in China. We included STB inpatients at Beijing Chest Hospital from January 2009 through December 2018. The multiple demographic and clinical variables of patients were collected from the hospital's electronic patient record. In total, 3086 STB patients were hospitalized in Beijing Chest Hospital. Of these cases, 1988 (64.4%) were spinal TB cases, 991 (32.1%) were joint TB cases, and 107 (3.5%) were concurrent spinal-joint TB cases. The most frequent localization of the infections in joints included the knee (21.5%), hip (17.9%), and elbow (10.3%). For spinal TB, lumbar, thoracic, and cervical spinal TB were present in 51.7%, 40.6%, and 4.4% of cases, respectively. Positive cultures were reported in only 16.0% of STB cases. When patients aged ≥ 60 years old were used as the control group, youths (< 18 years old) were less likely to have spinal TB (aOR, 0.29; 95% CI, 0.21-0.41). The prevalence of MDR-TB was 12.5% among the STB cases, and more female cases were afflicted with drug-resistant STB than with drug-susceptible STB (aOR, 0.50; 95% CI, 0.27-0.94). In addition, patients aged < 18 years had significantly higher odds of having drug-resistant STB compared with those aged ≥ 60 years (aOR, 20.778; 95% CI, 4.49-96.149). In conclusion, our data demonstrate that spinal TB is the most frequent form of STB in China. The youths are less likely to have spinal TB compared with elderly patients, while the patients aged < 18 years have significantly higher odds of having drug-resistant STB than elderly patients.

Central Nervous System Tuberculosis : Etiology, Clinical Manifestations and Neuroradiological Features.

PURPOSE: As a result of multilateral migration and globalization in times of humanitarian crises, western countries face a possible increase in the incidence of central nervous system tuberculosis (CNS TB). The diagnosis of CNS TB is challenging and often delayed due to the manifold and often non-specific presentation of the disease. The aim of this review is to analyze and summarize imaging features and correlated clinical findings of CNS TB. METHODS: The different manifestations of CNS TB are explained and illustrated by characteristic neuroradiological as well as neuropathological findings. An overview on diagnostic and therapeutic approaches is provided. For clarity, tables summarizing the lesion patterns, differential diagnoses and diagnostic hints are added. RESULTS: The CNS TB can be manifested (1) diffuse as tuberculous meningitis (TBM), (2) localized as tuberculoma or (3) tuberculous abscess or (4) in extradural and intradural spinal infections. Information on clinical presentation, underlying pathology and the distinguishing features is demonstrated. The TBM is further described, which may lead to cranial nerve palsy, hydrocephalus and infarction due to associated arteritis of the basal perforators. The differential diagnoses are vast and include other infections, such as bacterial, viral or fungal meningoencephalitis, malignant causes or systemic inflammation with CNS. Complicating factors of diagnosis and treatment are HIV coinfection, multi-drug resistance and TB-associated immune reconstitution inflammatory syndrome (IRIS). CONCLUSIONS: Neurologists and (neuro-)radiologists should be familiar with the neuroradiological presentation and the clinical course of CNS TB to ensure timely diagnosis and treatment.

Diagnosis and treatment of tuberculosis of the foot and ankle-A literature review.

Foot osteoarticular tuberculosis is uncommon. Late diagnosis and sub-optimal management can lead to significant morbidity, deformity and even death. Preservation of life, limb and function can be achieved with prompt diagnosis and treatment. In 1882, Robert Koch published his discovery of mycobacterium tuberculosis as the causative agent of tuberculosis (TB), and showed the disease was infectious rather than inherited. Over two centuries later, TB remains one of the top 10 causes of death worldwide. Whilst in 90% of cases TB infects the respiratory system, in 10% it is extrapulmonary and can infect the skeletal, nervous, lymphatic and genitourinary systems. The spine is the most frequently affected site in the musculoskeletal system and this is known as Pott's disease. The foot and ankle is affected in only 0.13% cases of extrapulmonary TB. A high index of suspicion is thus required. This infrequency in incidence, heterogeneity of its presentation along with the difficulty in early diagnosis often causes significant delays in its treatment and hence results in a considerable disability. The medical treatment is well established but the role of surgery, its usefulness and its correct timing remain controversial. The main diagnostic issues include imaging being non-specific. Plain radiographs remain the first line imaging modality. MRI and CT scans provide greater detail and capture the disease at an earlier stage. Microbiological testing has low sensitivity and specificity becasue TB lesions are paucibacillary. Bone biopsy is of significant diagnostic value as it not only allows histological examination to detect granulomas but enables sensitivity and resistance testing of anti-tuberculous therapy (ATT). Issues relating to treatment include timing, duration, combination of chemotherapy and the challenge of multi drug resistant tuberculosis MDR-TB. The selection and timing of appropriate surgical techniques and optimal duration of follow-up are further points to consider. In this article we aim to review the literature on diagnosis and treatment of foot and ankle TB.

Osteitis of the radius following Bacillus Calmette-Guérin vaccination at birth: a case report.

BACKGROUND: The Bacillus Calmette-Guérin vaccine, which is used for the prevention of tuberculosis, is considered protective against the severe forms of childhood tuberculosis. However, some serious adverse reactions including osteitis of the long bones can occur. CASE PRESENTATION: We report a case of an 18-month-old Sudanese girl who presented at the age of 3 months with swelling of her left forearm following Bacillus Calmette-Guérin vaccination administered at birth. Radiological and histological investigations confirmed tuberculous osteitis of the distal radius. She responded very well to antituberculous treatment with complete healing at follow-up visits. To the best of our knowledge this is the first case report of osteitis of the radius following Bacillus Calmette-Guérin vaccination described from Sudan. CONCLUSIONS: Bacillus Calmette-Guérin osteitis, although rare, should be considered a possible complication of the Bacillus Calmette-Guérin vaccination, and early diagnosis and treatment are essential.

Tuberculous periprosthetic infection precipitated by infliximab therapy.

Biological therapy with TNF-α inhibitors have been increasingly used in the treatment of inflammatory arthritis. Systemic tuberculosis infections are often known to occur following treatment with these biological agents. However, no case of periprosthetic tuberculous infection of the hip following this therapy has been reported. We report a case of a 45-year-old man who developed periprosthetic tuberculous infection soon after infliximab injection. We also discuss the need of pretreatment awareness, high index of suspicion, early diagnosis and management of such case.

[Tuberculous prosthetic knee joint infection: a case report and literature review]. / Artritis tuberculosa sobre prótesis de rodilla: descripción de un caso y revisión de la literatura.

OBJECTIVE: Prosthetic late infection occurs in the second month after surgery in the context of haematogenous spread from another source. Prosthetic mycobacterial infection is a rare complication whose clinical management is not standardized. CASE: Patient of 77 years with no personal history except for diabetes and a prosthetic replacement of right knee with osteoarthritis three years ago. Patient goes to hospital emergency box for 6 months pain in the right knee with mechanical inflammatory signs but no fever associated. After their return within 5 days and clinical worsening is reporting growth of Mycobacterium tuberculosis in knee aspirate and antitubercular treatment is established for 9 months. Nuclear magnetic resonance imaging studies also confirmed the diagnosis of tuberculosis spondylitis in the clinical context of the patients. After surgery, M. tuberculosis was again isolated from intraoperative samples and therefore the patient received another batch of treatment for 9 months. After a year of monitoring, the development was acceptable but few months later, the patient died for cardiovascular causes. In the literature review, 15 publications with a total of 17 clinical cases of prosthetic infection by M. tuberculosis were found from 1980 to 2014. CONCLUSIONS: Prosthetic tuberculous arthritis, although it is a rare presentation, it should be noted, especially in patients with predisposing conditions with a history of tuberculosis infection.

Posttraumatic tuberculous osteomyelitis of the foot--A rare case report.

Skeletal tuberculosis developing after trauma is a rare occurrence.We report a rare case of posttraumatic tubercular osteomyelitis of mid-tarsal bone of the right foot. Patient was treated with regular dressing and anti-tubercular drugs. Posttraumatic skeletal tuberculosis should be considered in patient with non-healing ulcer.

Analysis of 30 patients with acupuncture-induced primary inoculation tuberculosis.

Primary inoculation tuberculosis is a skin condition that develops at the site of inoculation of Mycobacterium tuberculosis in tuberculosis-free individuals. This report describes the diagnosis, treatment and >1 year follow-up of 30 patients presenting with acupuncture-induced primary inoculation tuberculosis. Our data provide a deeper insight into this rare route of infection of tuberculosis. We also review effective treatment options.

Tubercular prosthetic knee joint infection.

This article reports a rare case of late-onset tubercular infection following total knee arthroplasty in a 60-year-old woman who had been treated with a full course of antitubercular therapy for latent tuberculosis almost 25 years ago. Because no clear guidelines exist for optimal management of disease reactivation in the prosthetic knee joint, the authors performed a literature review and attempted to provide a treatment algorithm based on the time of presentation. Two modes of presentation were identified for unsuspected tubercular prosthetic joint infections based on the onset of symptoms and time to diagnosis: an early-onset presentation that occurs within the first 6 to 8 weeks postoperatively and a late-onset presentation that usually manifests after 8 weeks. Early-onset presentations often can be treated with standard antitubercular chemotherapy alone, whereas late-onset presentation may require 2-stage reimplantation under cover of antitubercular medications. This report also highlights the fact that despite adequate treatment of latent tuberculosis, patients may remain at risk of prosthetic joint infection following total knee arthroplasty.

Tubercular arthritis of the elbow joint following olecranon fracture fixation and the role of TGF-beta in its pathogenesis.

Tuberculosis (TB) occurring after a closed bone fracture in the patient with no history of TB and no evidence of TB infection at the time of initial fracture is a rare entity. We report one such case of a 48-year-old female, who presented in the emergency department with an olecranon fracture which was open reduced and internally fixed with tension band wiring. Patient presented in the outpatient department with serosanguineous discharge at 3 weeks after surgery. The discharge was sent for culture and sensitivity tests, and the patient was managed by antibiotics and daily dressings. There was wound dehiscence and the underlying implant was exposed, which was removed at 12 weeks after surgery. Repeat debridements and dressings continued for 6 months, but the discharge from the wound site continued. X-rays of the elbow performed at 6 months raised the suspicion of TB, which was confirmed by Ziel-Neelsen staining and histopathological examination of the debrided tissue. Following the confirmation, patient was put on antitubercular drugs. The patient responded to antitubercular drug therapy (ATT), the purulent discharge from the wound ceased, and eventually the wound healed after 2 months of starting ATT.
