Abstract
We report a case of brucellosis-induced severe neutropenia in a 2-year-old girl who presented with a 2-week history of fever. On clinical examination, the patient was febrile with mild aphthous stomatitis. However, her general condition was stable, and systemic examination did not show involvement of any other organ. Laboratory test results revealed severe neutropenia, mild anemia, and an elevated serum C-reactive protein level. Flow cytometry of peripheral blood leukocytes revealed no malignancy, and blood film morphology was unremarkable except for mild microcytosis and hypochromia. Antineutrophil antibody and Coombs test results were negative. We administered intravenous cefuroxime; however, therapy was switched to meropenem plus clarithromycin because fever persisted for 5 days, despite treatment. On the 10th day after admission, Brucella serology tests showed positive results, and trimethoprim-sulfamethoxazole plus rifampicin therapy was prescribed for 8 weeks. The fever defervesced, and the child was discharged in a good state of health. Neutropenia persisted for several months but gradually resolved. Neutropenia, defined as an absolute neutrophil count (ANC) < 1.5 cells × 10 9 /L beyond the first year of life, is a benign transient condition associated with an intercurrent infection (usually viral illnesses or infections) in immunocompetent children. However, severe neutropenia (ANC < 0.5 × 10 9 /L) associated with fever necessitates hospitalization and administration of broad-spectrum antibiotics to avoid the high risk of sepsis, particularly in children. Brucellosis is rarely associated with hematologic abnormalities such as neutropenia. Early diagnosis of hematologic complications of brucellosis is essential for prompt initiation of specific and aggressive treatment.

Abstract
Introduction: The aim of this study is to evaluate the demographic, clinical and laboratory characteristics and treatment results of pediatric patients followed up with the diagnosis of brucellosis in our clinic.Methods: Patients who were followed up with the diagnosis of brucellosis in Kayseri Training and Research Hospital, Pediatric Infectious Diseases Clinic between October 2016 and December 2018 were retrospectively analyzed.Results: A total of 37 patients, 26 (70.3%) male, were included in the study. The mean age of the patients whose ages ranged from 1 to 17 years was 9.3±4.3 years. Unpasteurized milk and/or dairy products were consumed in 86.5% of the patients and 48.6% had a family history of brucellosis. Joint pain (75.7%) was the most common presenting complaint. In the laboratory evaluation, 8.1% of the patients had leukopenia, 2.7% had thrombocytopenia and 21.4% had ALT elevation. Doxycycline plus rifampicin (43.2%) was the most commonly preferred treatment regimen. Addition of aminoglycoside to initial therapy in hospitalized patients was statistically higher than in outpatients (81.2% vs. 23.8%) (p=0.001). During the follow-up, relapse developed in a total of 4 (10.8%) patients, 3 of whom were outpatients. There was no statistical relationship between the initial treatment regimen and relapse (p=0.418).Conclusion: In conclusion, brucellosis should be kept in mind in terms of differential diagnosis in patients who present with joint pain in our country and who have cytopenia and/or isolated aminotransferase elevation in their investigations.Keywords: Child, Brucellosis, Relapse

Abstract
Brucellosis is a major zoonotic disease caused by Brucella species. Historically, the disease received over fifty names until it was recognized as a single entity, illustrating its protean manifestations and intricacies, traits that generated conundrums that have remained or re-emerged since they were first described. Here, we examine confusions concerning the clinical picture, serological diagnosis, and incidence of human brucellosis. We also discuss knowledge gaps and prevalent confusions about animal brucellosis, including brucellosis control strategies, the so-called confirmatory tests, and assumptions about the primary-binding assays and DNA detection methods. We describe how doubtfully characterized vaccines have failed to control brucellosis and emphasize how the requisites of controlled safety and protection experiments are generally overlooked. Finally, we briefly discuss the experience demonstrating that S19 remains the best cattle vaccine, while RB51 fails to validate its claimed properties (protection, differentiating infected and vaccinated animals (DIVA), and safety), offering a strong argument against its current widespread use. These conundrums show that knowledge dealing with brucellosis is lost, and previous experience is overlooked or misinterpreted, as illustrated in a significant number of misguided meta-analyses. In a global context of intensifying livestock breeding, such recurrent oversights threaten to increase the impact of brucellosis.

Abstract
INTRODUCTION Human brucellosis is one of the most common zoonotic infections in the world. The definitive diagnosis of brucellosis is based on cultured Brucella organisms from blood or other tissue samples. We aimed to compare bacteremic and nonbacteremic brucellosis patients with demographical, epidemiological, clinical and laboratory features and determine the predictive factors affecting blood culture positivity. MATERIALS AND METHODS Children aged 1 month to 18 years who were followed up with the diagnosis of brucellosis between January 2005 and March 2021 were included in this retrospective study. According to the isolation of Brucella melitensis in blood culture, the patients were divided into two groups as bacteremic and nonbacteremic and compared in terms of demographic, clinical and laboratory characteristics. RESULTS One hundred eighty-nine (116 male, 61.4%) patients diagnosed with brucellosis were included in the study. There were 76 (40.2%) bacteremic and 113 (59.8%) nonbacteremic patients. Bacteremic patients were younger than nonbacteremic patients. Fever, arthralgia, hepatomegaly and splenomegaly were significantly higher in the culture positive group. High levels of C-reactive protein (CRP), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were found to be significant in the bacteremic group. CONCLUSION In our study, history of fever and arthralgia, hepatomegaly and splenomegaly in physical examination and high CRP, ALT and AST levels in the biochemical analysis were important factors determining blood culture positivity.

Prevalence and relevant factors of positive RF in brucellosis patients with arthralgia. PLoS Negl Trop Dis 2021; 15:e0009749. [PMID: 34543280 PMCID: PMC8452007 DOI: 10.1371/journal.pntd.0009749] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/05/2020] [Accepted: 08/22/2021] [Indexed: 02/03/2023] Open
Abstract
Background Brucellosis is a critical zoonotic disease in the world, it is the non-specific arthralgia that make brucellosis patients easily misdiagnosed as rheumatoid arthritis (RA) in endemic regions. Elevated rheumatoid factor (RF) is an essential indicator of RA, and the RF in brucellosis patients is significantly higher than healthy people. Therefore, this study further explored the distribution of RF and the relevant factors of the RF positivity in brucellosis patients with arthralgia, in order to strengthen the recognition of physicians for brucellosis patients with RF positivity, especially in brucellosis-endemic areas, so as to avoid misdiagnosis and untimely treatment that may lead to malignant outcomes. Methodology and principal findings The medical records of all 572 brucellosis inpatients were collected in the Sixth People’s Hospital of Shenyang, China from 2015 to 2016. After excluding 106 patients without arthralgia, 5 patients who unwilling to perform RF testing and 16 patients with diseases that may affect RF, 445 brucellosis inpatients with arthralgia were involved in this retrospective cross-sectional study. 143 (32.1%) patients with RF >10 IU/ml were classified into the RF positive group, with an average level of 16.5[12.2, 34.7] IU/ml, of which 45 (10.1%) patients were high-positive with RF >30 IU/ml. Multivariate logistic regression model was used to further analyze the relevant factors of the RF positivity and found that age, wrist joint pain and elevated C-reactive protein (CRP) were positively associated with RF positivity, with OR of 1.02 (P = 0.024), 8.94 (P = 0.008) and 1.79 (P = 0.019), respectively. Conclusion The prevalence of positive RF in brucellosis patients with arthralgia was critical, nearly one-third of patients had RF positive. Elderly men brucellosis patients with arthralgia, wrist joint pain and elevated CRP were at high risk of positive RF. It is reminded that physicians should focus on differential diagnosis during clinical diagnosis and treatment, especially in brucellosis-endemic regions. Brucellosis is a highly contagious zoonosis caused by Brucella spp., which compromises to organs and systems, causing non-specific symptoms such as fever, headache, sweating, fatigue, myalgia and arthralgia. Similarly, patients with rheumatoid arthritis (RA) may also have the above non-specific symptoms. It is precisely because of the non-specificity and similarity of symptoms that brucellosis patients were easily misdiagnosed and failed to receive timely treatment, resulting in neurosis, chronic fatigue syndrome, endocarditis and other adverse outcomes. However, rheumatoid factor (RF) is an essential indicator of RA, and the RF in brucellosis patients is significantly higher than healthy people. In order to strengthen the recognition of physicians for brucellosis patients with RF positivity, we conducted this research and found that the prevalence of positive RF in brucellosis patients with arthralgia was common and critical. Elderly men brucellosis patients with arthralgia, wrist joint pain and elevated CRP were at high risk of positive RF. It is reminded that physicians should pay attention to the possibility of brucellosis during clinical diagnosis and treatment, especially in brucellosis-endemic regions, which had certain clinical significance.

Abstract
Childhood brucellosis present various non-specific clinical symptoms, and limited laboratory data exist for clinical diagnosis. A better understanding of these clinical and laboratory characteristics can avoid clinical misdiagnosis and mistreatment. In this case-series study, a total of 78 children with confirmed diagnosis of brucellosis were evaluated retrospectively. We observed that the incidence rate was higher in the first two quarters every year. The most common symptom was fever. Osteoarticular involvement was found in 44.87% of the patients. Laboratory tests showed that the values of erythrocyte sedimentation rate(ESR), C-reactive protein(CRP), Hemoglobin(Hb), Neutrophils(NEU), Alanine aminotransfease(ALT) and Ferritin in childhood brucellosis with osteoarticular involvement had significant differences than those without osteoarticular involvement or control group (P<0.05). Childhood brucellosis without osteoarticular involvement often accompanied by decrease of NEU , increase of CRP and ALT compared with that control group (P<0.05). The Receiver Operating Curves (ROC) analysis revealed that NEU, CRP and ALT can be used as adjunct parameters in the differential diagnosis of childhood brucellosis. These data suggest that clinical and laboratory characteristics are very important for every clinician, which may have a complementary role in diagnosis of childhood brucellosis.

Abstract
Background Brucellosis is recognized as a neglected zoonotic disease and a major public health threat. The purpose of this study was to characterize epidemiological risk factors and healthcare utilization and compare clinical aspects of disease among adult and pediatric cases in North Texas. Methods A retrospective chart review of electronic medical records was completed at 3 large tertiary centers—Parkland Health and Hospital System, Clements University Hospital, and Children’s Medical Center—between January 1, 2007 and June 1, 2017. Demographic, clinical, and laboratory variables were collected. Cases were defined as confirmed or probable. Results Twenty-eight cases of brucellosis were identified: 26 confirmed (9 children, 17 adults) and 2 probable cases (1 child, 1 adult). Half (n = 14) were diagnosed in 2016 during an outbreak in Dallas County. Risk factors associated with infection were consumption of unpasteurized cheese (71%), recent travel (54%), close contact to a confirmed human brucellosis case (36%), and exposure to animals (11%). Median days of symptoms was 10 and 16 for children and adults, respectively. The majority (79%) of patients visited the emergency department before diagnosis and 93% were hospitalized. Fever was the most common symptom in children (80%) and adults (100%). Hepatitis (75% of children) and anemia (82% of adults) were the most common laboratory abnormalities. The most common complication in children was splenic lesions (40%), and the most common complication in adults was hepato/splenomegaly (39%). Conclusions The diagnosis of Brucella infection requires a high index of suspicion and should be considered in patients presenting with a febrile illness and a compatible exposure history.

Abstract
BACKGROUND Brucellosis is endemic in Iran. Children constitute 20-25% of cases. We determined clinical, laboratory, and epidemiologic characteristics of pediatric brucellosis patients hospitalized at the Children's Medical Center from May 2011 to December 2016. METHODS Medical records were reviewed retrospectively. For each patient, a questionnaire was provided containing demographic characteristics (sex, age, nationality, date of admission, city of residence, history of ingestion of unpasteurized dairy products, family history of brucellosis, history of contact with suspicious animals) and clinical information (signs and symptoms, laboratory findings, history of disease relapse, treatment). RESULTS Included were 43 patients diagnosed with brucellosis (26 males, 60.5%; age 1-13 years, mean ± SD: 7.02 ± 3.5). A history of ingestion of raw or unpasteurized dairy products was present in 88% (N = 38) and 11 patients (26%) had had contact with a suspicious animal. Highest frequencies of brucellosis were recorded in 2013 (N = 10, 23%) and 2015 (N = 11, 26%). Most cases were admitted in the summer (N = 14, 33%) and spring (N = 12, 28%). Fever (N = 39, 91%), arthralgia (N = 33, 77%), and malaise (N = 33, 77%) were the main complaints. Anemia (65%), lymphocytosis (51%), and elevated erythrocyte sedimentation rate (86%) and C‑reactive protein (67%) were the most prominent blood anomalies. Blood culture was positive in 30% (N = 11/37), bone marrow culture in 31% (N = 4/11). A positive Wright, Coombs Wright, and 2 ME test was observed in 67% (N = 29), 92% (N = 34/37), and 85% (N = 34/40) of cases, respectively. Median length of antibiotic therapy was 12 weeks (2-24 weeks). The most frequent drug regimen was combined trimethoprim-sulfamethoxazole and rifampicin (N = 24, 56%). Relapse occurred in 9 patients (21%), there were no deaths. CONCLUSIONS Physicians should be aware of the manifestations, diagnosis, and treatment protocols of childhood brucellosis. Control programs and preventive measures, e.g., regular examination of domestic animals, mass vaccination of livestock, slaughter of infected animals, control of animal trade and migration, pasteurization of milk and milk products, training and increased public awareness of the dangers of consumption of unpasteurized dairy products, are highly recommended.

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
We investigated the incidence of and risk factors for liver involvement (LI) in patients with brucellosis in Turkey. Diagnosis was established by blood cultures (BCs) or compatible clinical presentation accompanied by serological evidence. Patients received either a combination of doxycycline plus rifampin for 6 weeks or doxycycline for 6 weeks plus streptomycin intramuscularly for the first 2 weeks. Liver function tests, including those for alanine (ALT) and aspartate aminotransferase (AST) levels, were monitored before and at the end of treatment. One hundred and ninety-five patients were included in the study. Seventy patients had elevated transaminases before treatment. Twenty-six patients had a positive BC for brucellosis. In multivariate analysis, BC positivity (OR=2.44, 95 % CI: 1.03-5.78, P=0.043) and serum agglutination titre (SAT) (OR=1.001, 95 % CI: 1.00-1.002, P=0.018) were found to be associated with LI. Serum aminotransferase levels were normalized in all patients with brucellosis. BC positivity and high SAT are independent factors that are associated with LI in patients with brucellosis.

BACKGROUND Brucellosis is a common zoonosis in the Bedouin population of southern Israel. Limited data exist for the rate and risk factors of hematologic complication of brucellosis in children. We assessed anemia, leukopenia, thrombocytopenia and pancytopenia in childhood brucellosis in southern Israel. METHODS Our medical center is the sole hospital in southern Israel. All medical files of brucellosis, 2005-2014, identified through positive blood cultures or International Classification of Diseases 9th revision coding with positive serology, were reviewed retrospectively. RESULTS Overall, 511 brucellosis episodes were identified; 42% (N = 214) with ≥1 cytopenia, including 13% (N = 68) anemia, 28% (N = 144) leukopenia, 14% (N = 74) thrombocytopenia and 2% (N = 9) pancytopenia. Overall, 99.8% of episodes were in Bedouin children and 70% in males. In 79% of episodes, blood culture was positive for Brucella melitensis. Acute infections comprised 84% of all episodes. In univariate analysis, older age (10.49 ± 4.81 vs. 9.25 ± 4.89 years), fever (92% vs. 78%), positive blood culture (84% vs. 75%) and IgM ≥1:640 levels (50% vs. 39%) were associated with cytopenia. In contrast, arthralgia was associated with noncytopenic episodes. In multivariate analyses, older age (odds ratio = 1.063) and fever (odds ratio = 3.127) were associated with cytopenia. CONCLUSIONS Brucellosis is commonly presented with cytopenia, especially in bacteremic episodes with fever. However, pancytopenia is uncommon and its finding should alert the physician to look for other possible etiologies.

Abstract
Crimean-Congo hemorrhagic fever (CCHF) is a tick-borne disease with high mortality. Many disorders can mimic CCHF. It is important to recognize the condition and to perform differential diagnosis in endemic countries. Twenty-one children aged 18 years or less with a preliminary diagnosis of CCHF were retrospectively evaluated. Real-time PCR and a confirmatory indirect immunofluorescence assay for negative results were performed. The diagnoses determined that 9 patients had (42.9%) CCHF; 7 patients had (33.3%) viral upper respiratory tract infections (URTI); 2 patients had (9.5%) brucellosis; 1 patients had (4.7%) periodic fever, aphthous stomatitis, pharyngitis, and adenitis (PFAPA) syndrome episode; 1 patient had (4.7%) cerebral palsy, diabetes insipidus, acute gastroenteritis, and hypernatremic dehydration; and 1 patient had (4.7%) cellulitis after a tick bite. The mean age of patients with CCHF was greater than that of the other patients (116.1±53.6 vs. 94.1±52.1 months, p=0.02). Seventeen (81%) of the children included had a history of tick bites, 2 (9.5%) had a history of contact with a patient with CCHF, and 2 (9.5%) had no exposure, but were living in an endemic region. Three patients had an underlying disorder: cerebral palsy and diabetes insipidus, epilepsy, or PFAPA. All of the children experienced fever. Other frequent symptoms were malaise, diarrhea, vomiting, and abdominal pain, but none of these differed statistically between the patient groups. CCHF patients had a longer mean duration of symptoms (10.56±1.42 vs. 6.75±3.62 days, p=0.008) and a longer mean length of hospitalization (8.00±2.08 vs. 3.58±1.56 days, p<0.001) than the other patients. At laboratory examination, patients with CCHF had statistically significant lower leukocyte and platelet counts, more prolonged coagulation parameters, and greater AST, ALT, LDH, and CK levels than the other patients. No mortality or complications occurred in the study. Both infectious causes, such as URTI, cellulitis, and brucellosis, and non-infectious causes may resemble CCHF. Although they are not pathognomonic, some indicators, including a longer symptom duration and hospitalization, cytopenia, elevated liver enzymes, creatine kinase and prolonged coagulation parameters, were found to be in favor of CCHF.
