Hassan MA, Noor F, Salehi A, Al Hariri B. Brucellosis an Unusual presentation as isolated septic mono-arthritis of the knee joint: A case report. Heliyon 2024; 10:e26612. [PMID: 38420443 PMCID: PMC10901018 DOI: 10.1016/j.heliyon.2024.e26612] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/28/2023] [Revised: 02/03/2024] [Accepted: 02/16/2024] [Indexed: 03/02/2024] Open
Abstract
Brucellosis is a zoonotic infection that is widely spread across the world. It is becoming more common in Middle Eastern countries such as Qatar, Saudi Arabia, and the Mediterranean region. Despite this, we need to remain vigilant as it is still prevalent in many parts of the world. The most common presentation is musculoskeletal, but it can also present as septic arthritis in the sacroiliac, hip, or knee joints. Brucella melitensis was only found in one extended culture of synovial fluid. Treatment involved a combination of antimicrobial therapy using gentamycin, doxycycline, and rifampin. A high level of suspicion for brucellosis is necessary for any patient coming from an endemic region with non-specific and chronic arthritis to ensure early diagnosis and treatment. In this case, we present a 28-year-old male who was diagnosed with Brucellosis after developing acute septic arthritis.

Abstract
Key Clinical Message The main target of this report was that brucellosis can occur in unexpected and very rare patterns. We reported this patient to acknowledge all of clinicians especially those living in the endemic areas, that these rare complications of brucellosis can also be treated by the standard treatment of this disease. Abstract Brucellosis is a thousand-face disease and common zoonotic infection in endemic regions. A 42-year-old female was admitted with sternoclavicular arthritis and breast abscess. After laboratory investigation and imaging, positive serological test results and positive blood culture for Brucella revealed acute sternoclavicular arthritis and breast abscess due to brucellosis.

B. abortus Infection Promotes an Imbalance in the Adipocyte–Osteoblast Crosstalk Favoring Bone Resorption. Int J Mol Sci 2023; 24:ijms24065617.

Abstract
Osteoarticular injury is the most common presentation of active brucellosis in humans. Osteoblasts and adipocytes originate from mesenchymal stem cells (MSC). Since those osteoblasts are bone-forming cells, the predilection of MSC to differentiate into adipocytes or osteoblasts is a potential factor involved in bone loss. In addition, osteoblasts and adipocytes can be converted into each other according to the surrounding microenvironment. Here, we study the incumbency of B. abortus infection in the crosstalk between adipocytes and osteoblasts during differentiation from its precursors. Our results indicate that soluble mediators present in culture supernatants from B. abotus-infected adipocytes inhibit osteoblast mineral matrix deposition in a mechanism dependent on the presence of IL-6 with the concomitant reduction of Runt-related transcription factor 2 (RUNX-2) transcription, but without altering organic matrix deposition and inducing nuclear receptor activator ligand kβ (RANKL) expression. Secondly, B. abortus-infected osteoblasts stimulate adipocyte differentiation with the induction of peroxisome proliferator-activated receptor γ (PPAR-γ) and CCAAT enhancer binding protein β (C/EBP-β). We conclude that adipocyte–osteoblast crosstalk during B. abortus infection could modulate mutual differentiation from its precursor cells, contributing to bone resorption.

Abstract
Erythema nodosum (EN) is the most common panniculitis which affects individuals from all ages. Etiologically most of the cases are idiopathic EN and infections rank the second. Its clinical presentation is sudden, hot erythematous nodules or plaques in legs, knees or ankles with a diameter ranging between 1 and 5 cm. In the majority of cases, healing is observed within two to eight weeks without any scar tissues. It may occasionally manifest itself as the first symptom of systemic diseases such as sarcoidosis, inflammatory bowel diseases, Behçet’s disease, and other rheumatological conditions. Therefore, EN cases must be carefully examined in terms of their etiologies. Herein, we report an interesting Brucella case presenting as a EN case consulted for rheumatological etiology investigation.

Abstract
Brucellosis is a zoonotic infection caused by facultative intracellular bacteria of the genus Brucella. The ability of the organism to invade both phagocytic and non-phagocytic cells and survive in the intracellular environment makes brucellosis a systemic infection that can affect various organs of the body. Complications of brucellosis occur when the infection involves one or more focal body sites. Early identification of complications of brucellosis and initiation of appropriate treatment is the key to a better outcome. Here we present two cases of complicated brucellosis, both having multiple body site involvement.

Abstract
Brucellosis is a bacterial disease of domestic animals and humans. The pathogenic ability of Brucella organisms relies on their stealthy strategy and their capacity to replicate within host cells and to induce long-lasting infections. Brucella organisms barely induce neutrophil activation and survive within these leukocytes by resisting microbicidal mechanisms. Very few Brucella-infected neutrophils are found in the target organs, except for the bone marrow, early in infection. Still, Brucella induces a mild reactive oxygen species formation and, through its lipopolysaccharide, promotes the premature death of neutrophils, which release chemokines and express "eat me" signals. This effect drives the phagocytosis of infected neutrophils by mononuclear cells that become thoroughly susceptible to Brucella replication and vehicles for bacterial dispersion. The premature death of the infected neutrophils proceeds without NETosis, necrosis/oncosis, or classical apoptosis morphology. In the absence of neutrophils, the Th1 response exacerbates and promotes bacterial removal, indicating that Brucella-infected neutrophils dampen adaptive immunity. This modulatory effect opens a window for bacterial dispersion in host tissues before adaptive immunity becomes fully activated. However, the hyperactivation of immunity is not without a price, since neutropenic Brucella-infected animals develop cachexia in the early phases of the disease. The delay in the immunological response seems a sine qua non requirement for the development of long-lasting brucellosis. This property may be shared with other pathogenic alphaproteobacteria closely related to Brucella We propose a model in which Brucella-infected polymorphonuclear neutrophils (PMNs) function as "Trojan horse" vehicles for bacterial dispersal and as modulators of the Th1 adaptive immunity in infection.

Abstract
Brucella is caused by a Gram-negative bacillus and is a common disease in endemic areas where people are in close contact with animals and dairy products, but brucellar cervical epidural abscess is rare. We describe a rare case of a C5–6 brucellar epidural abscess in a veterinary doctor who was treated with decompression and instrumentation. We also review the cases of cervical brucellar epidural abscess treated with instrumentation in the literature.

Interaction of Brucella abortus with Osteoclasts: a Step toward Understanding Osteoarticular Brucellosis and Vaccine Safety. Infect Immun 2020; 88:IAI.00822-19.

Abstract
Osteoarticular disease is a frequent complication of human brucellosis. Vaccination remains a critical component of brucellosis control, but there are currently no vaccines for use in humans, and no in vitro models for assessing the safety of candidate vaccines in reference to the development of bone lesions currently exist. While the effect of Brucella infection on osteoblasts has been extensively evaluated, little is known about the consequences of osteoclast infection. Murine bone marrow-derived macrophages were derived into mature osteoclasts and infected with B. abortus 2308, the vaccine strain S19, and attenuated mutants S19vjbR and B. abortus ΔvirB2 While B. abortus 2308 and S19 replicated inside mature osteoclasts, the attenuated mutants were progressively killed, behavior that mimics infection kinetics in macrophages. Interestingly, B. abortus 2308 impaired the growth of osteoclasts without reducing resorptive activity, while osteoclasts infected with B. abortus S19 and S19vjbR were significantly larger and exhibited enhanced resorption. None of the Brucella strains induced apoptosis or stimulated nitric oxide or lactose dehydrogenase production in mature osteoclasts. Finally, infection of macrophages or osteoclast precursors with B. abortus 2308 resulted in generation of smaller osteoclasts with decreased resorptive activity. Overall, Brucella exhibits similar growth characteristics in mature osteoclasts compared to the primary target cell, the macrophage, but is able to impair the maturation and alter the resorptive capacity of these cells. These results suggest that osteoclasts play an important role in osteoarticular brucellosis and could serve as a useful in vitro model for both analyzing host-pathogen interactions and assessing vaccine safety.

Abstract
BACKGROUND Brucellosis is a systemic infectious disease frequently associated with osteoarticular involvement. While sacroiliitis is a common manifestation of brucellosis, septic osteoarthritis is less frequent. Here, we report two cases of septic osteoarthritis caused by Brucella melitensis. CASE PRESENTATION Both patients had a history of contact with goats before admission. Upon clinical examination, they showed marked pain and limited movement in the hip. Imaging findings revealed obvious osteonecrosis of the right femoral head. Inflammatory markers, including erythrocyte sedimentation rate and C-reactive protein level, were elevated. The tube agglutination test results of both patients were positive (1:160 and 1:200). Real-time polymerase chain reaction analysis of synovial fluid revealed the presence of B. melitensis. We deduced that septic osteoarthritis could explain these clinical and radiological findings. Both patients were followed-up for 12 months. They returned to their normal routine after completing a standard antibiotic regimen, including doxycycline (100 mg, daily) and rifampicin (600 mg), for 6 weeks. CONCLUSIONS Brucellar hip arthritis is a serious clinical manifestation of brucellosis, presenting mainly as marked joint pain and limited mobility. It is characterized by joint effusion, synovitis, and soft-tissue swelling on magnetic resonance images. Physicians should consider brucellosis as one of the differential diagnoses of arthritis.

Abstract
Brucellosis, caused by the intracellular bacterial pathogen Brucella, is a globally important zoonotic disease for which arthritis is the most common focal complication in humans. Wild-type mice infected systemically with Brucella typically do not exhibit arthritis, but mice lacking IFN-γ develop arthritis regardless of the route of Brucella infection. Here, we investigated mechanisms by which IFN-γ suppresses Brucella-induced arthritis. Several cell types, including innate lymphoid cells, contributed to IFN-γ production and suppression of joint swelling. IFN-γ deficiency resulted in elevated joint IL-1β levels, and severe joint inflammation that was entirely inflammasome dependent, and in particular, reliant on the NLRP3 inflammasome. IFN-γ was vital for induction of the nitric oxide producing enzyme, iNOS, in infected joints, and nitric oxide directly inhibited IL-1β production and inflammasome activation in Brucella-infected macrophages in vitro. During in vivo infection, iNOS deficiency resulted in an increase in IL-1β and inflammation in Brucella-infected joints. Collectively, this data indicate that IFN-γ prevents arthritis both by limiting Brucella infection, and by inhibiting excessive inflammasome activation through the induction of nitric oxide.

Abstract
BACKGROUND Infection of bones and joints remains one of the most commonly described complications of brucellosis in humans and is predominantly reported in all ages and sexes in high-risk regions, such as the Middle East, Asia, South and Central America, and Africa. We aimed to systematically review the literature and perform a meta-analysis to estimate the global prevalence of osteoarticular brucellosis (OAB). METHODOLOGY Major bibliographic databases were searched using keywords and suitable combinations. All studies reporting the incidence and clinical manifestations of osteoarticular brucellosis in humans, and demonstrated by two or more diagnostic methods (bacteriological, molecular, serological, and/or radiographic) were included. Random model was used, and statistical significance was set at 0.05. PRINCIPAL FINDINGS A total of 56 studies met the inclusion criteria and were included in the systematic review and meta-analysis. There was an evidence of geographical variation in the prevalence of osteoarticular disease with estimates ranging from 27% in low-risk regions to 36% in high-risk regions. However, the difference was not significant. Thus, brucellosis patients have at least a 27% chance of developing osteoarticular disease. CONCLUSIONS The prevalence of OAB is not dependent on the endemicity of brucellosis in a particular region. Hence, further research should investigate the potential mechanisms of OAB, as well as the influence of age, gender, and other socioeconomic factor variations in its global prevalence, as this may provide insight into associated exposure risks and management of the disease.

Abstract
Brucellosis, caused by the intracellular bacterial pathogen Brucella, is a zoonotic disease for which arthritis is the most common focal complication in humans. Here we investigated the role of inflammasomes and their effectors, including interleukin-1 (IL-1), IL-18, and pyroptosis, on inflammation and control of infection during Brucella-induced arthritis. Early in infection, both caspase-1 and caspase-11 were found to initiate joint inflammation and proinflammatory cytokine production. However, by 1 week postinfection, caspase-1 and caspase-11 also contributed to control of Brucella joint infection. Inflammasome-dependent restriction of Brucella joint burdens did not require AIM2 (absent in melanoma 2) or NLRP3 (NLR family, pyrin domain containing 3). IL-1R had a modest effect on Brucella-induced joint swelling, but mice lacking IL-1R were not impaired in their ability to control infection of the joint by Brucella In contrast, IL-18 contributed to the initiation of joint swelling and control of joint Brucella infection. Caspase1/11-dependent cell death was observed in vivo, and in vitro studies demonstrated that both caspase-1 and caspase-11 induce pyroptosis, which limited Brucella infection in macrophages. Brucella lipopolysaccharide alone was also able to induce caspase-11-dependent pyroptosis. Collectively, these data demonstrate that inflammasomes induce inflammation in an IL-18-dependent manner and that inflammasome-dependent IL-18 and pyroptosis restrict Brucella infection.

Abstract
Literature reporting on lumber brucella spondylitis (LBS) is rare, therefore, the purpose of this study was to evaluate the outcomes of one-stage surgical management for lumber brucella spondylitis by anterior debridement, autogenous grafts, and instrumentation. This was a retrospective cohort study including 16 patients with lumber brucella spondylitis by treated from January 2009 to October 2011 in our department. All cases underwent one-stage anterior internal fixation, debridement, and bone fusion; clinical and radiographic results were analyzed and compared. All patients were followed up for an average of 35.3 ± 8.1 months (range, 24-48 months). Brucella spondylitis was completely cured in all patients with bone fusion achieved in 4.8 ± 1.3 months. Visual analog scale (VAS) scores were significantly improved between the preoperative and last follow-up visit and neurological function classification showed significant improvement after surgical intervention. Preoperatively, the Cobb angle was 20.7 ± 9.8°, and measured 8.1 ± 1.3° at the last follow-up visit. The outcomes of follow-up demonstrated that one-stage surgical treatment with anterior debridement, fusion, and instrumentation can be an effective and feasible treatment method for lumber brucella spondylitis.

Abstract
STUDY DESIGN Clinical case series. OBJECTIVE The aim of this study was to explore the efficacy and safety of one-stage debridement, autogenous bone graft, and instrumentation for lumbar brucella spondylitis (LBS) via a posterior approach. SUMMARY OF BACKGROUND DATA Reports on LBS are sporadic, and the therapeutic effect and safety of surgical interventions have not been assessed in clinical studies. METHODS Between January 2012 and January 2014, 24 consecutive patients with symptomatic LBS who underwent a one-stage operation that combined debridement, autogenous bone graft, and instrumentation via a posterior approach were enrolled. Back pain was measured using the visual analog scale (VAS). The neurological status was evaluated with the American Spinal Injury Association (ASIA) scale. Bone healing was evaluated based on postoperative plain x-ray or computed tomography. RESULTS All cases were followed up for an average of 14.3 + 3.5 months. The VAS scores were significantly improved at every follow-up interval. An improvement of at least one grade level was observed in the ASIA score of each patient. The average time of bone fusion was 6.8 + 1.6 months. Significant improvements of the average segmental Cobb angle was observed from a preoperative value of 18.4° + 4.6° to a last follow-up value of 21.1° ± 3.7°. At the last follow up, the titers of antibodies against the standard tube agglutination test, erythrocyte sedimentation rate, and C-reactive protein were negative for all patients. CONCLUSION For LBS, systemic antibrucellosis chemotherapy is the cornerstone of treatment. When cauda equine syndrome, radiculopathy, spinal instability, and severe back pain caused by extradural nonabsorbable abscess or progressive collapse are present, surgical intervention is inevitable. One-stage debridement, autogenous bone graft, and instrumentation via a posterior approach could represent an alternative treatment for LBS, and the efficacy and safety of these techniques are satisfactory.

Abstract
Although Brucella species is known to affect almost all organs in humans, renal involvement presenting as acute pyelonephritis remains a rare entity in brucellosis. We report the case of a female patient who presented with symptoms of fever with chills, right loin pain and dysuria in the emergency room. Blood cultures drawn at the time of admission grew Brucella spp., but no organisms were isolated from urine culture although urinalysis data was indicative of urinary tract infection. Empiric therapy with piperacillin/tazobactam plus gentamicin relieved her symptoms. However, the treatment was switched to doxycycline plus rifampicin once the blood culture result was obtained.

Abstract
Brucella abortus is an intracellular bacterium that establishes lifelong infections in livestock and humans although the mechanisms of its chronicity are poorly understood. Activated B cells have long lifespan and B. abortus infection activates B cells. Our results indicate that the direct infection of B cells with B. abortus induced matrix metalloproteinase-9 (MMP-9), receptor activator for NF κB ligand (RANKL), tumor necrosis factor (TNF)-α and interleukin (IL)-6 secretion. In addition, supernatants from B. abortus-infected B cells induced bone marrow-derived monocytes to undergo osteoclastogenesis. Using osteoprotegerin, RANKL's decoy receptor, we determined that RANKL is involved in osteoclastogenesis induced by supernatants from B. abortus-infected B cells. The results presented here shed light on how the interactions of B. abortus with B cells may have a role in the pathogenesis of brucellar osteoarticular disease.

Abstract
Brucellosis is one of the commonest zoonotic infections worldwide. The disease is endemic in Saudi Arabia, the Middle East, and the Mediterranean area. Osteoarticular involvement is a frequent manifestation of brucellosis. It tends to involve the sacroiliac joints more commonly; however, spondylitis and peripheral arthritis are increasingly reported. Brucellosis can be overlooked especially in the presence of companion bacteria. Hence, it should be suspected in all patients with septic arthritis in endemic areas or in patients visiting such areas.

Abstract
PURPOSE The aim of this work was to detect subclinical sacroiliac joint involvement in patients with brucellosis and study their clinical and laboratory features. PATIENTS AND METHODS The study included 100 brucellosis patients being followed-up in the Gastroenterology and Hepatology Unit, Theodor Bilharz Research Institute and Cairo University outpatient clinics. A thorough history, physical examination, routine laboratory tests, and abdominal ultrasound were obtained for all patients. Extended rheumatological examination was performed including clinical testing for sacroiliitis and enthesitis. None of the patients reported a history of back pain or any symptoms suggestive of sacroiliitis during the course of the infection. Plain x-ray and MRI scan of the sacroiliac joints were performed for all patients. RESULTS Asymptomatic sacroiliitis was present in 24 % of the brucellosis patients; none of the patients had tenderness over their spine with preserved lumbar spine mobility. Sacroiliitis was mainly unilateral being bilateral in 20.83 %. There was an obvious relationship with animal contact and occupation of the patients. Osteoarticular involvement was common (67 %) including arthralgias, arthritis, myalgias, spondylitis, enthesitis and bursitis, being clearly higher in those with sacroiliitis. The MRI scan showed blurring of the margins in 66.67 %, widening in 25 %, narrowing in 54.17 %, erosions in 20.83 %, and sclerosis in 12.5 %. CONCLUSION Osteoarticular manifestations of brucellosis are prevalent and subclinical sacroiliitis is evident, a finding that may classify these patients as having brucellar spondyloarthropathy (BSA). Referring brucellosis patients for rheumatological assessment has the advantage of early assessment of asymptomatic cases with sacroiliitis which is commonly overlooked.

Abstract
BACKGROUND/PURPOSE To present clinical and laboratory features, treatment options, and outcome in patients with brucellar testicular infection and to compare them with analogous in brucellar patients without testicular involvement. METHODS Thirty four brucellar patients with testicular infection treated in two general hospitals in the Republic of Macedonia, during the period 1998-2009, were retrospectively analyzed. Their clinical and laboratory characteristics were compared with analogous in 364 male brucellar patients without testicular infection, who were treated at the same hospitals during the same time period. RESULTS Brucellar testicular infection was evident in 34 (8.5%) out of 398 male patients with brucellosis. The median age of the patients was 46.5 years. In all patients testicular involvement was presented as an acute form with a median duration of 5 days (range, 2-14 days) prior to diagnosis. Twenty-three of the patients had at least one other simultaneous focal infection. After starting with the treatment testicular infection lasted a median 10 days, range 7-21 days. Brucellar patients with testicular infection when compared with other brucellar patients more frequently manifested fever (97% vs. 61%), concomitant spondylitis (32% vs. 16%), and urinary system involvement (12% vs. 2%). Also, the relapse rate in patients with testicular involvement was significantly higher (24% vs. 9%). CONCLUSION In endemic regions brucellosis should be taken into consideration in any patient with testicular infection. Brucellar testicular involvement is usually characterized with a severe acute clinical presentation and a high percentage of relapses which entails the need of timely recognition and proper treatment duration of at least 60 days.

Abstract
BACKGROUND Brucella species are facultative intracellular gram-negative bacteria that cause brucellosis, a common global zoonosis. Infection of the joints is the most common focal complication of brucellosis in humans. The purpose of this study was to identify mediators of focal inflammation during brucellosis. METHODS Wild-type (WT) mice are naturally resistant to Brucella infection; therefore, we infected anti-interferon γ (IFN-γ)-treated, or IFN-γ(-/-) mice with Brucella to induce osteoarticular and musculoskeletal inflammation, as we previously described. Mice were infected intraperitoneally with Brucella melitensis, and the clinical course of disease, histopathologic changes, and cytokine levels were compared among groups. RESULTS Rag1(-/-) mice (B- and T-cell deficient) and µMT(-/-) mice (B-cell deficient) developed paw inflammation at a similar rate and severity as WT mice following infection with B. melitensis and treatment with anti-IFN-γ. Joints from B. melitensis-infected IFN-γ(-/-) mice had markedly increased levels of CCR2 and CXCR2 ligands. While anti-IFN-γ-treated CCR2(-/-) and WT mice behaved similarly, anti-IFN-γ-treated CXCR2(-/-) or IFN-γ(-/-)/CXCR2(-/-) mice had strikingly reduced focal swelling relative to anti-IFN-γ-treated WT or IFN-γ(-/-) mice, respectively. Additionally, neutrophil recruitment was dependent on CXCR2. CONCLUSIONS Adaptive immune cells and CCR2 are dispensable, while CXCR2 is necessary for Brucella-induced focal neutrophil recruitment and inflammation.

Abstract
INTRODUCTION Brucellosis is a public health problem that is prevalent in several developing countries. METHODS The clinical and laboratory characteristics of 164 cases of brucellosis in Bursa, Turkey, were retrospectively evaluated. RESULTS The ages of the 164 patients ranged from 15-85 years. All of the patients underwent the Rose Bengal test and 163 (99.4%) patients tested positive. 122 (74.4%) patients were diagnosed with acute brucellosis, 31 (18.9%) with subacute brucellosis and 11 (6.7%) with chronic brucellosis. Focal involvement was found in 101 (61.6%) patients. Although patients with focal involvement had a higher white blood cell count (p = 0.002), those without focal involvement had higher aspartate transaminase and alanine transaminase values, and lower platelet values (p = 0.005, 0.007 and 0.039, respectively). Spondylodiscitis was observed on imaging in 58 (66.7%) of the 87 patients who presented with back pain. Among the 118 patients who were examined within the first month of treatment, 79 (66.9%) responded to treatment. The relapse rate was 11.6% among all 164 patients. CONCLUSION Brucellosis should be considered as a differential diagnosis among patients who present with fever, and joint or back pain. Focal involvement should be investigated in the presence of leucocytosis, and subacute or chronic forms of brucellosis. To identify cases of spondylodiscitis, radiography should be performed in patients who present with back pain.

Brucella abortus Invasion of Osteocytes Modulates Connexin 43 and Integrin Expression and Induces Osteoclastogenesis via Receptor Activator of NF-κB Ligand and Tumor Necrosis Factor Alpha Secretion. Infect Immun 2015; 84:11-20.

Abstract
Osteoarticular brucellosis is the most common localization of human active disease. Osteocytes are the most abundant cells of bone. They secrete factors that regulate the differentiation of both osteoblasts and osteoclasts during bone remodeling. The aim of this study is to determine if Brucella abortus infection modifies osteocyte function. Our results indicate that B. abortus infection induced matrix metalloproteinase 2 (MMP-2), receptor activator for NF-κB ligand (RANKL), proinflammatory cytokines, and keratinocyte chemoattractant (KC) secretion by osteocytes. In addition, supernatants from B. abortus-infected osteocytes induced bone marrow-derived monocytes (BMM) to undergo osteoclastogenesis. Using neutralizing antibodies against tumor necrosis factor alpha (TNF-α) or osteoprotegerin (OPG), RANKL's decoy receptor, we determined that TNF-α and RANKL are involved in osteoclastogenesis induced by supernatants from B. abortus-infected osteocytes. Connexin 43 (Cx43) and the integrins E11/gp38, integrin-α, integrin-β, and CD44 are involved in cell-cell interactions necessary for osteocyte survival. B. abortus infection inhibited the expression of Cx43 but did not modify the expression of integrins. Yet the expression of both Cx43 and integrins was inhibited by supernatants from B. abortus-infected macrophages. B. abortus infection was not capable of inducing osteocyte apoptosis. However, supernatants from B. abortus-infected macrophages induced osteocyte apoptosis in a dose-dependent manner. Taken together, our results indicate that B. abortus infection could alter osteocyte function, contributing to bone damage.

Abstract
BACKGROUND CONTEXT Brucellosis remains an important economic and public health problem in some parts of the world. The spine is the most common site of musculoskeletal involvement of brucellosis. PURPOSE Assess the clinical, laboratory, radiological findings, and outcomes of vertebral involvement in brucellosis. STUDY DESIGN A retrospective study. PATIENT SAMPLE Thirty-two patients with spinal brucellosis during a period of 21 years (1990-2010) were included. OUTCOME MEASURES Clinical and radiological improvement. METHODS Diagnosis made on clinical presentation, laboratory findings, radiographic evidence, and the Brucellar etiology was considered when seroagglutination tests were positive at a titer of 1/160 or higher, and/or Brucella spp were isolated in the blood or sample cultures. RESULTS The mean age of patients was 51±15.85 years (23 males, 9 females; age range, 19-74 years). The median diagnostic delay was 3 months. Back or neck pain (100% of patients), fever (78%), and sweats (68.6%) were the most common symptoms. Cultures of blood specimens from five patients (15.6%) were positive for Brucella melitensis. Four patients (12.5%) had motor weakness or paralysis. Magnetic resonance imaging was performed in 24 (75%) cases. Paravertebral masses, epidural masses, and psoas abscesses were detected in 65.6%, 59.4%, and 28.1% of patients, respectively. The lumbar vertebra was the most frequently involved region with the rate of 68.7%, followed by thoracal (18.7%), cervical (6.3%), lumbosacral (6.3%), and thoracolumbar (3.1%) segments. The duration of antimicrobial therapy of brucellosis (median, 6 months; range, 3-13 months) varied according to clinical response and the presence of epidural and paravertebral masses. There were no deaths or severe sequelae in this study. CONCLUSIONS Brucellar spondylitis should be considered in patients with back pain and fever in endemic areas. A high index of suspicion and clinical, laboratory, and radiological examinations help to confirm the diagnosis of vertebral involvement.

Abstract
Brucellosis is a protean disease and should be excluded in any febrile child with a constellation of symptoms such as fever, malaise, sweating, arthralgia, and joint swelling in endemic areas. Skeletal system involvement is the most common source of complaints in brucellosis. The frequency of skeletal involvement in children is 6.4% to 73.5%. There are some controversies regarding the most common sites of involvement: sacroiliac versus peripheral joints. In the vast majority of cases, peripheral joint involvement in pediatric brucellosis has a monoarticular pattern, although there is no agreement about the most commonly involved peripheral joint. In this systematic review, published articles that describe the bone involvement of Brucella melitensis, as the most prevalent kind of the microorganism in the region, in children are evaluated.

Abstract
AIM To describe the main clinical and laboratory characteristics, frequency and distribution of osteoarticular involvement, therapeutic options and outcome in children with osteoarticular brucellosis. METHODS This descriptive study includes 133 pediatric patients with osteoarticular brucellosis who were treated at the University Clinic for Infectious Diseases and Febrile Conditions in Skopje, Republic of Macedonia, during the period between 1989 and 2011. Brucellosis was presumptively diagnosed on the basis of clinical signs and confirmed by the detection of specific antibodies at significant titers. RESULTS The median age of patients was 9 years (range, 2-14 years) and 63.9% were males. Family history of brucellosis was present in 54.1%. The dominant clinical symptoms were arthralgia and fever in 77.4% and 73.7%, respectively, and the dominant sign was hepatomegaly in 73.7% of patients. The main laboratory abnormalities were elevated C-reactive protein (81.0%) and circulating immunocomplexes (80.7%). In 71.4% of patients, the osteoarticular involvement was monoarticular. Hip arthritis was present in 49.6%, followed by the knee in 30.1%. Various therapeutic regimens with a duration of 6 weeks were used. In 87 patients during a follow-up of at least 6 months, relapse occurred in 13.8%. CONCLUSIONS Osteoarticular involvement is frequent in children with brucellosis. It is most often manifested with monoarthritis of the large weight-bearing joints. Brucellosis should be included in the differential diagnosis of childhood arthritis in endemic countries, especially in the presence of family history, contact with infected animals or ingestion of unpasteurized food products, fever and hepatomegaly.

Abstract
Arthritis is one of the most common complications of human active brucellosis, but its pathogenic mechanisms have not been completely elucidated. In this paper, we describe the role of synoviocytes in the pathogenesis of brucellar arthritis. Our results indicate that Brucella abortus infection inhibited synoviocyte apoptosis through the upregulation of antiapoptotic factors (cIAP-2, clusterin, livin, and P21/CIP/CDNK1A). In contrast, infection did not change the expression of proteins that have been involved in apoptosis induction such as Bad, Bax, cleaved procaspase 3, CytC, and TRAIL, among others; or their expression was reduced, as occurs in the case of P-p53(S15). In addition, B. abortus infection induced upregulation of adhesion molecules (CD54 and CD106), and the adhesion of monocytes and neutrophils to infected synoviocytes was significantly higher than to uninfected cells. Despite this increased adhesion, B. abortus-infected synoviocytes were able to inhibit apoptosis induced by supernatants from B. abortus-infected monocytes and neutrophils. Moreover, B. abortus infection increased soluble and membrane RANKL expression in synoviocytes that further induced monocytes to undergo osteoclastogenesis. The results presented here shed light on how the interactions of B. abortus with synovial fibroblasts may have an important role in the pathogenesis of brucellar arthritis.

Abstract
Background The objectives of this systematic review, commissioned by WHO, were to assess the frequency and severity of clinical manifestations of human brucellosis, in view of specifying a disability weight for a DALY calculation. Methods/Principal Findings Thirty three databases were searched, with 2,385 articles published between January 1990–June 2010 identified as relating to human brucellosis. Fifty-seven studies were of sufficient quality for data extraction. Pooled proportions of cases with specific clinical manifestations were stratified by age category and sex and analysed using generalized linear mixed models. Data relating to duration of illness and risk factors were also extracted. Severe complications of brucellosis infection were not rare, with 1 case of endocarditis and 4 neurological cases per 100 patients. One in 10 men suffered from epididymo-orchitis. Debilitating conditions such as arthralgia, myalgia and back pain affected around half of the patients (65%, 47% and 45%, respectively). Given that 78% patients had fever, brucellosis poses a diagnostic challenge in malaria-endemic areas. Significant delays in appropriate diagnosis and treatment were the result of health service inadequacies and socioeconomic factors. Based on disability weights from the 2004 Global Burden of Disease Study, a disability weight of 0.150 is proposed as the first informed estimate for chronic, localised brucellosis and 0.190 for acute brucellosis. Conclusions This systematic review adds to the understanding of the global burden of brucellosis, one of the most common zoonoses worldwide. The severe, debilitating, and chronic impact of brucellosis is highlighted. Well designed epidemiological studies from regions lacking in data would allow a more complete understanding of the clinical manifestations of disease and exposure risks, and provide further evidence for policy-makers. As this is the first informed estimate of a disability weight for brucellosis, there is a need for further debate amongst brucellosis experts and a consensus to be reached. Brucellosis is a bacterial disease transmitted to humans by consumption of infected, unpasteurised animal milk or through direct contact with infected animals, particularly aborted foetuses. The livestock production losses resulting from these abortions have a major economic impact on individuals and communities. Infected people often suffer from a chronic, debilitating illness. This systematic review on the symptoms of human brucellosis is the first ever conducted. Using strict exclusion criteria, 57 scientific articles published between January 1990–June 2010 which included high quality data were identified. Severe complications of brucellosis infection were not rare, with 1 case of endocarditis and 4 neurological cases per 100 patients. One in 10 men suffered from testicular infection, which can case sterility. Debilitating conditions such as joint, muscle, and back pain affected around half of the patients. Given that most patients had fever, brucellosis poses a diagnostic challenge in malaria-endemic areas where fever is often assumed to be malaria. More high quality data is needed for a more complete understanding of the clinical manifestations of disease and exposure risks, and to provide further evidence for policy-makers.

Abstract
OBJECTIVE : Brucellar spondylitis is one of the most serious complications of brucellosis. It should be considered in patients who have back pain and neurologic disorders as well as systemic symptoms and findings in or from endemic areas such as Turkey. This report describes important features of the disease. METHODS : Twenty-five patients with brucellar spondylitis were retrospectively evaluated in terms of their clinical, laboratory, and radiologic features and their response to different treatment regimens. RESULTS : The most common symptoms of brucellar spondylitis were back pain, fever, and sweating. Rose Bengal tests were positive in all of these patients. Brucella species was isolated from blood cultures of 8 (32%) patients. Magnetic resonance imaging (MRI) showed that the lumbar segment was the most frequently involved region. Different combination regimens including 2 or 3 antibiotics were used. Combination of tetracycline (especially doxycycline) and streptomycin was the most widely used therapy regimen. Trimethoprim-sulfamethoxazole, ciprofloxacin, ofloxacin, and rifampin were also included in some combination therapies. In this series, the mean duration of antimicrobial therapy was 130 +/- 45.6 days (range, 77-281 days), and 92% of patients received therapy for >/= 90 days. There were no mortalities in this study. CONCLUSIONS : Brucellar spondylitis should be considered in patients with back pain and neurologic disorders as well as systemic symptoms and findings in endemic areas. MR imaging is recommended in suspected cases. The patients can be treated effectively treated with appropriate antibiotic combinations. Follow up is important because relapses can occur.

Abstract
Osteoarticular complications are common in human brucellosis, but the pathogenic mechanisms involved are largely unknown. In this manuscript, we described an immune mechanism for inflammatory bone loss in response to infection by Brucella abortus. We established a requirement for MyD88 and TLR2 in TNF-α-elicited osteoclastogenesis in response to B. abortus infection. CS from macrophages infected with B. abortus induced BMM to undergo osteoclastogenesis. Although B. abortus-infected macrophages actively secreted IL-1β, IL-6, and TNF-α, osteoclastogenesis depended on TNF-α, as CS from B. abortus-infected macrophages failed to induce osteoclastogenesis in BMM from TNFRp55⁻/⁻ mice. CS from B. abortus-stimulated MyD88⁻/⁻ and TLR2⁻/⁻ macrophages failed to express TNF-α, and these CS induced no osteoclast formation compared with that of the WT or TLR4⁻/⁻ macrophages. Omp19, a B. abortus lipoprotein model, recapitulated the cytokine production and subsequent osteoclastogenesis induced by the whole bacterium. All phenomena were corroborated using human monocytes, indicating that this mechanism could play a role in human osteoarticular brucellosis. Our results indicate that B. abortus, through its lipoproteins, may be involved in bone resorption through the pathological induction of osteoclastogenesis.

Abstract
Arthritis is one of the most common complications of human brucellosis, but its pathogenic mechanisms have not been elucidated. Fibroblast-like synoviocytes (FLS) are known to be central mediators of joint damage in inflammatory arthritides through the production of matrix metalloproteinases (MMPs) that degrade collagen and of cytokines and chemokines that mediate the recruitment and activation of leukocytes. In this study we show that Brucella abortus infects and replicates in human FLS (SW982 cell line) in vitro and that infection results in the production of MMP-2 and proinflammatory mediators (interleukin-6 [IL-6], IL-8, monocyte chemotactic protein 1 [MCP-1], and granulocyte-macrophage colony-stimulating factor [GM-CSF]). Culture supernatants from Brucella-infected FLS induced the migration of monocytes and neutrophils in vitro and also induced these cells to secrete MMP-9 in a GM-CSF- and IL-6-dependent fashion, respectively. Reciprocally, culture supernatants from Brucella-infected monocytes and neutrophils induced FLS to produce MMP-2 in a tumor necrosis factor alpha (TNF-α)-dependent fashion. The secretion of proinflammatory mediators and MMP-2 by FLS did not depend on bacterial viability, since it was also induced by heat-killed B. abortus (HKBA) and by a model Brucella lipoprotein (L-Omp19). These responses were mediated by the recognition of B. abortus antigens through Toll-like receptor 2. The intra-articular injection of HKBA or L-Omp19 into the knee joint of mice resulted in the local induction of the proinflammatory mediators MMP-2 and MMP-9 and in the generation of a mixed inflammatory infiltrate. These results suggest that FLS, and phagocytes recruited by them to the infection focus, may be involved in joint damage during brucellar arthritis through the production of MMPs and proinflammatory mediators.

Abstract
Brucellosis is a systemic infectious disease, which constitutes a public health problem in Turkey. Brucellosis has a broad spectrum of clinical manifestations. Osteoarthicular manifestations are often seen in brucellosis but most of the brucellar monoarthritis cases are reactive rather than being septic. We report a case of brucellar (septic) monoarthritis of the knee in a 74-year-old cattleman and review of the literature.

Abstract
Brucellosis is a zoonotic infection with a broad spectrum of clinical manifestations. The authors report the first case in the literature of septic arthritis of the knee 1 year after revision of anterior cruciate ligament reconstruction. Brucella melitensis biotype 3 was found in both synovial fluid and blood cultures. The patient was treated initially with arthroscopic debridement. After the diagnosis was confirmed, a second arthroscopic lavage and metal work removal was applied leaving the graft in place. Antimicrobial chemotherapy was prescribed for 3 months. The infection was fully eradicated and the patient is still asymptomatic, 4 years after the treatment.

Abstract
Osteoarticular complications are common in human brucellosis, but the pathogenic mechanisms involved are largely unknown. Since matrix metalloproteinases (MMPs) are involved in joint and bone damage in inflammatory and infectious diseases, we investigated the production of MMPs by human osteoblasts and monocytes, either upon Brucella abortus infection or upon reciprocal stimulation with factors produced by each infected cell type. B. abortus infection of the normal human osteoblastic cell line hFOB 1.19 triggered a significant release of MMP-2, which was mediated in part by granulocyte-macrophage colony-stimulating factor (GM-CSF) acting on these same cells. Supernatants from infected osteoblasts exhibited increased levels of monocyte chemoattractant protein 1 and induced the migration of human monocytes (THP-1 cell line). Infection with B. abortus induced a high MMP-9 secretion in monocytes, which was also induced by heat-killed B. abortus and by the Omp19 lipoprotein from B. abortus. These effects were mediated by Toll-like receptor 2 and by the action of tumor necrosis factor alpha (TNF-α) produced by these same cells. Supernatants from B. abortus-infected monocytes induced MMP-2 secretion in uninfected osteoblasts, and this effect was mediated by TNF-α. Similarly, supernatants from infected osteoblasts induced MMP-9 secretion in uninfected monocytes. This effect was mediated by GM-CSF, which induced TNF-α production by monocytes, which in turn induced MMP-9 in these cells. These results suggest that MMPs could be potentially involved in the tissue damage observed in osteoarticular brucellosis.

Abstract
Brucellosis, an endemic disease in certain parts of the world is usually accompanied by osteoarticular involvement. The present study was performed to determine the types and frequency of rheumatologic manifestations in patients with brucellosis diagnosed in the north of Iran. Diagnosis of active brucellosis was based on the serological tests along with compatible clinical findings. Musculoskeletal involvement of brucellosis was confirmed by clinical and radiographic examinations; 51 (32 males, 19 females) patients with mean (SD) age of 35 (19) years old were studied. Rheumatological manifestations were observed in 94% of patients. The most frequent skeletal findings in order of frequency were peripheral arthritis, sacroiliitis; and spondylitis which occurred in 37; 31 and 8% of patients, respectively. Back pain, arthralgia, myalgia, and enthesopathy were also reported in 49, 34, 11.7% of patients, respectively. Based on the findings of this study, rheumatologic manifestations are common in brucellosis; therefore, in the endemic areas, brucellosis should be considered in the differential diagnosis of patients who present with any type of rheumatologic manifestations.

Abstract
A case of 65-year-old farmer who presented with Brucella-related cervical spondylitis is described. Because of the advanced form of the infection resulted in neurological impairment, cervical vertebra corpectomy and debridement of the paravertebral granulomatous tissue deposits were performed followed by stabilization with anterior plating and bone grafting. In addition, double antimicrobial chemotherapy regimen was administered for 12 weeks. After one year, follow up evaluation demonstrated resolution of the infection. The authors recommend that brucellosis should be included in the differential diagnosis of cervical spondylitis, particularly in patients who reside in countries where the zoonosis is still endemic.

Abstract
Brucellosis is a systemic infection involving many organs and tissues. The musculoskeletal system is one of the most commonly affected. The disease can present with sacroiliitis, peripheral arthritis, spondylitis, paraspinal abscess, bursitis, and osteomyelitis. A 25-year-old male patient was admitted with fever of 20-day duration, right-sided hip pain, and night sweating. A Brucella standard tube agglutination test was positive at a titer of 1/160. Magnetic resonance imaging (MRI) of the hip joint showed right sacroiliitis and a hyperintense, nodular, lobulated mass within the right iliacus muscle, consistent with abscess. The patient was started on intramuscular streptomycin at a dose of 1 g/day, oral rifampin 600 mg/day, and doxycycline 200 mg/day. On day 20 of treatment, the patient was admitted with swelling and pain over the left elbow for the past week. MRI of the left elbow was performed, which showed fluid edema suggestive of olecranon bursitis. Taking the patient's complaints into consideration, rifampin and doxycycline treatment were maintained for a year. Pain at the hip joint and elbow resolved and MRI findings disappeared. Abscess of the iliacus muscle, which has not been reported before, and the olecranon bursitis that developed during treatment make this case worth presenting.

Abstract
The ability of Brucella spp. to infect human osteoblasts and the cytokine response of these cells to infection were investigated in vitro. Brucella abortus, B. suis, B. melitensis, and B. canis were able to infect the SaOS-2 and MG-63 osteoblastic cell lines, and the first three species exhibited intracellular replication. B. abortus internalization was not significantly affected by pretreatment of cells with cytochalasin D but was inhibited up to 92% by colchicine. A virB10 mutant of B. abortus could infect but not replicate within osteoblasts, suggesting a role for the type IV secretion system in intracellular survival. Infected osteoblasts produced low levels of chemokines (interleukin-8 [IL-8] and macrophage chemoattractant protein 1 [MCP-1]) and did not produce proinflammatory cytokines (IL-1beta, IL-6, and tumor necrosis factor alpha [TNF-alpha]). However, osteoblasts stimulated with culture supernatants from Brucella-infected human monocytes (THP-1 cell line) produced chemokines at levels 12-fold (MCP-1) to 17-fold (IL-8) higher than those of infected osteoblasts and also produced IL-6. In the inverse experiment, culture supernatants from Brucella-infected osteoblasts induced the production of IL-8, IL-1beta, IL-6, and TNF-alpha by THP-1 cells. The induction of TNF-alpha and IL-1beta was largely due to granulocyte-macrophage colony-stimulating factor produced by infected osteoblasts, as demonstrated by inhibition with a specific neutralizing antibody. This study shows that Brucella can invade and replicate within human osteoblastic cell lines, which can directly and indirectly mount a proinflammatory response. Both phenomena may have a role in the chronic inflammation and bone and joint destruction observed in osteoarticular brucellosis.

Abstract
There is little information in the literature on the clinical progress of brucellosis in patients affected by other non-infectious diseases; however, the infection can often trigger an exacerbation of existing underlying conditions in certain target organs. In this report we present four cases of brucellosis complicating previous diseases, and the difficulties in relation to their diagnosis and treatment. The study involved four patients with the following disorders: polycythaemia vera, pulmonary fibrosis, cirrhosis of the liver and arthritis of the knee. Brucellosis was diagnosed by classical serological and bacteriological methods. The strains involved could be isolated only in three of the four patients: two strains were Brucella abortus biovar 1 and one was Brucella suis biovar 1. Two patients relapsed 10 and 7 months after admission, another presented chronic brucellosis and received various therapy schemes, and one died. Since the best selection of antibiotics and the optimal duration of therapy remain unknown for patients having brucellosis complicated by previous pathologies, these remain at the discretion of the attending physician. Management of our patients was controversial in terms of the selection of antibiotics, duration of treatment and decision regarding surgery.

Abstract
Brucella infection in arthroplasties is a rare event. An unspecific clinical symptomatology is associated with unclear radiographic peri-prosthetic signs of bone halisteresis. Only a positive anamnesis, combined with an antibiogram of the joint liquid and a high serum antibody titre, can lead to a definitive diagnosis. We report a case of Brucella melitensis infection in a total knee arthroplasty implanted 2 years earlier. With the absence of radiological signs of prosthetic loosening and thanks to a systemic antibiotic combined therapy (rifampicin + doxycycline) extended for 8 weeks, we were able to solve the infection avoiding surgery.

Abstract
Brucellosis is a zoonotic disease caused by a number of Brucella species and is characterized by chronic macrophage infection. However, genes that may contribute to intracellular survival of the Brucella species are not well studied. This review presents, first, genomic islands that are present or absent in various Brucella species that may help establish Brucella infection and survival strategies. Second, the alteration in macrophage transcription by Brucella to permit its long-term survival within this hostile intracellular environment. A large number of macrophage gene transcripts are altered following Brucella infection indicating that Brucella is not a silent invader of host cells. Macrophage transcript levels associated with inflammation, apoptosis, signal transduction and vesicular intracellular trafficking are altered during Brucella infection, and likely contribute to intracellular survival of Brucella. Lastly, the host-pathogen interaction events associated with Brucella infection in living mice visualized in real-time using biophotonic imaging. Mice are often used to evaluate Brucella infections; however, Brucella dissemination and pathogenesis is poorly understood in mice. Biophotonic imaging of Brucella infections revealed sites of bacterial localization similar to human infections and different patterns of infection by attenuated or virulent Brucella.

Abstract
A young male immigrant from Syria with a vasculitic-appearing leg rash, asymmetrical polyarthritis, microscopic haematuria, and raised inflammatory markers was provisionally diagnosed with Henoch-Schönlein purpura. Skin biopsy showed leukocytoclastic vasculitis. Low-grade fevers persisted despite non-steroidal anti-inflammatory therapy, and Brucella sp. was subsequently grown from both blood and synovial fluid aspirates. Further tests gave positive results for B. abortus, and triple antibiotic therapy produced a rapid clinical response. Cutaneous vasculitis has rarely been described in brucellosis, and this is the first report in the English medical literature of brucellosis mimicking Henoch-Schönlein purpura.

Abstract
OBJECTIVE To determine the frequency and clinical characteristics of osteoarticular complications of brucellosis in an endemic region in Iran. METHODS In a prospective study we evaluated 245 patients with brucellosis diagnosed between January 2004 and December 2005. Patients included were those older than 8 years of age and who had clinical features suggestive of brucellosis and specific antibodies at significant titers, and/or positive blood or body fluid culture for Brucella species. A bone scan was performed in those with a clinical suspicion of osteoarticular involvement. RESULTS Seventy patients (28.6%) had osteoarticular complications. Sacroiliitis was the most common complication (75.7%), followed by spondylitis (21.4%) and peripheral arthritis (8.6%). Spondylitis was the most common osteoarticular complication in the elderly. Relapses occurred in five (2%) patients, three of them with spondylitis. CONCLUSIONS Osteoarticular disease is the most common complication of brucellosis in Western Iran. Sacroiliitis is the most common form of osteoarticular complication. With the use of a proper treatment regimen, the prospect for recovery is good.

Abstract
Bursal infection is an uncommon clinical presentation of brucellosis. We herein report a case of Brucella melitensis bursitis that was successfully treated. Other reported cases of brucella bursitis were reviewed. A high degree of suspicion in the right clinical setting is required for the diagnosis of brucella bursitis.

Abstract
A systematic review of the presentation and management of prosthetic joint infection (PJI) due to zoonotic microorganisms, fungi, mycobacteria and other unusual microorganisms is not available. We therefore sought to provide a resource for the practicing orthopaedic surgeon which will serve as a guide for making appropriate decisions in managing such rare, but potentially problematic conditions. We conducted a Medline search of all case reports of PJI due to these unusual microorganisms. Our review of the current literature showed the diagnosis of PJI due to zoonotic microorganisms, fungi, mycobacteria and other unusual microorganisms typically necessitates specialized diagnostic tests. Maintaining a high index of suspicion in diagnosis of such unusual microorganisms and requesting the appropriate laboratory tests at the time of surgical débridement is crucial for determining the microbiologic etiology of these infections. The appropriate medical and surgical management of such infections is complex and often requires the use of special antimicrobials with which the orthopaedist may not be familiar. Collaboration with an infectious disease specialist is advisable when treating these infections.

Abstract
AIMS To describe the distribution of bone and joint involvement in 197 patients with brucellosis, and to detail a spectrum of findings on bone scintigraphy in 38 patients with brucellar spondylitis. METHODS One hundred and ninety-seven patients (141 females, 56 males; age range, 5-77 years) with osteoarticular brucellosis were studied. Patients were classified into acute (62%) and chronic (38%) stages of the disease, and into age groups of less than 16 (1%), 16-30 (17%), 31-45 (29%), 46-60 (37%) and over 60 (16%) years. All patients were evaluated with Tc-methylene diphosphonate bone scanning. Quantification of sacroiliac joint uptake was performed to improve the sensitivity for the detection of sacroiliitis. Plain radiography and computed tomography (CT) or magnetic resonance imaging (MRI) were performed, when required, to evaluate the areas of the skeleton that showed abnormal uptake on the bone scan. MRI and single photon emission computed tomography (SPECT) were performed in all patients who had spinal lesions. RESULTS The sites most commonly affected were the sacroiliac joints (53%) and spine (19%), followed by the shoulders (16%). Osteoarticular involvement was more common in females (72%) than in males (28%), and the acute stage (62%) was observed more than the chronic stage (38%). Bone and joint involvement occurred at any age, but the most common age group was 46-60 years. Eight scintigraphic patterns were identified in spinal involvement. CONCLUSION Brucellosis may affect the musculoskeletal system at any site. Bone scan is a useful method to detect osteoarticular involvement in cases of relapse and progression. Spine involvement has the widest range of scintigraphic findings. A knowledge of the location and distribution of osteoarticular involvement as revealed on the bone scan of patients with brucellosis may be valuable in patient treatment and management.

Abstract
Brucellosis is a zoonosis that affects several organs and has a protean presentation. The authors report the case of a 61-year-old male patient with brucellar spondylodiscitis involving several vertebrae and a paravertebral abscess localized in the erector spinae muscle. Diagnosis was made by positive blood culture and MRI. No relapse was seen with a combined treatment (doxycycline/rifampin) for 3 months, followed by doxycycline alone for 6 months. Almost all radiologic findings disappeared at the end of a 1-year follow-up without any further treatment.
