The management of prolonged fever in low-socioeconomic-status areas by primary care providers such as general practitioners is challenging. Given the endemic nature of many infectious diseases, physicians typically start empirical antibiotic therapy following a limited diagnostic workup including serologic examinations. Herein, we report the case of a young male patient with prolonged fever and arthralgia initially diagnosed with and treated for brucellosis but with a confirmed diagnosis of systemic lupus erythematosus on follow-up. This unique case shows that close follow-up is the best practice for managing prolonged fever in cases with non-specific laboratory findings.

BACKGROUND/AIMS: Brucellosis patients present various non-specific clinical symptoms, such as fever, fatigue, sweating, joint pain, arthritis, myalgia, and headache. Based on the nonspecifity of its clinical signs and symtoms, we decided to evaluate whether mean platelet volume (MPV) , neutrophil to lymphocyte ratio (NLR), and platelet to lymphocyte ratio (PLR) will contribute to the diagnosis. METHODS: In this retrospective study, we reviewed hospital-records of 60 children with a confirmed diagnosis of brucellosis in Kayseri between January 2013 and January 2016, and compared the hematological parameters; white blood cell (WBC) count, hemoglobin (Hb), neutrophil count, lymphocyte count, platelet count, MPV, NLR, and PLR with 55 healthy age and gender matched children. Also, the well known inf lammation markers; erytrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were compared between the patient and control group. RESULTS: We found significant difference among the Hb, platelet count, MPV and NLR values between the patient and control group (p < 0.05). There was no difference between WBC, neutrophil count, lymphocyte count and PLR between the patient and control group (p > 0.05). When the patients were divided into groups as arthritis positive and arthritis negative and compared to the control group; we found that the NLR is more significant in between the arthritis positive and control group (p = 0.013). Also, we found significant difference among the ESR and CRP values between the patient and control group (p < 0.001). CONCLUSIONS: The results of this study indicates that MPV and NLR values can be used as markers of inflammation in childhood brucellosis. Also, NLR is more valuable in children with brucella arthritis.

Although the development of the 2009 SpA classification criteria by Assessment of SpondyloArthritis international Society (ASAS) represents an important step towards a better definition of the early disease stage particularly in axial spondyloarthritis (axSpA), the specificity of the criteria has been criticized these days. As the commonest zoonotic infection worldwide, human brucellosis can mimic a large number of diseases, including SpA. This study was performed to determine the frequency of rheumatologic manifestations in patients with brucellosis and the chance of misdiagnosing them as having axSpA in central China. The results showed that clinical manifestations of axSpA could be observed in brucellosis. Over half of patients had back pain, and one fifth of the patients with back pain were less than 45 years old at onset and had the symptom for more than 3 months. Two young males were falsely classified as suffering from axSpA according to the ASAS criteria, and one with MRI proved sacroiliitis was once given Etanercept for treatment. Therefore, differential diagnosis including human brucellosis should always be kept in mind when applying the ASAS criteria, even in traditionally non-endemic areas.

The Brucella mdh gene was successfully cloned and expressed in E. coli. The purified recombinant malate dehydrogenase protein (rMDH) was reactive to Brucella-positive bovine serum in the early stage, but not reactive in the middle or late stage, and was reactive to Brucella-positive mouse serum in the late stage, but not in the early or middle stage of infection. In addition, rMDH did not react with Brucella-negative bovine or mouse sera. These results suggest that rMDH has the potential for use as a specific antigen in serological diagnosis for early detection of bovine brucellosis.

OBJECTIVETo evaluation the specificity and sensitivity of 5 kinds of serological detection methods about brucellosis.

METHODSTo investigate in the 4 autonomous banner (Cha You Hou Qi, Right-Wing Central Banner of Kerqin Region, Linxi County and Siziwangqi Banner) of Inner Mongolia autonomous region from January to December, 2013. Accepting criteria: professionals of breeding cattle and sheep, and slaughter,accompanied by Bloom's disease suspected symptoms such as fever, fatigue,arthralgia, ranging in age from 25 to 55 years old. To collect suspected patients venous blood 3-5 ml in the morning, a total of 236 samples were collected. To detect the Brucella antibody by using plate agglutination test (PAT), tiger red plate agglutination test (RBPT), standard test tube agglutination test (SAT), enzyme-linked immunosorbent assay (ELISA) and immune colloidal gold method (GICA), SAT was taken as a golden standard, analyzed the sensitivity and specificity of RBPT and SAT, ELISA and GICA.

RESULTSSAT method of positive patients: 136 cases (57.6%). PAT method positive patients: 150 cases (63.6%). RBPT positive patients: 159 cases (67.4%), and 143 patients with ELISA method: positive (60.6%), 147 patients with positive GICA method (62.3%). The detection rate of Brucella antibody positive was different by different testing methods.There was no significant difference (χ(2)=0.52,P=0.264). To take the SAT method as the gold standard, PAT, RBPT, ELISA and GICA method of the sensitivity were 97.7% (133/136), 98.5% (134/136), 94.8% (129/136) and 94.1% (128/136), respectively. The specificity was lower,the rate were 70.0% (70/100), 75.0% (75/100), 86.0% (86/100) and 81.0% (81/100), respectively. The total coincidence rate were 86.0% (203/236), 88.5% (209/236), 91.1% (215/236) and 88.5% (209/236), respectively.

CONCLUSIONThe specificity and sensitivity of ELISA and GICA method is higher in the diagnosis of disease. The two methods are rapid, GICA method can be used on-site testing, large sample test is suitable for using ELISA.

OBJECTIVETo investigate the epidemiological characteristics, clinical manifestations, diagnosis, and treatment of Brucella orchitis, so as to provide reliable evidence for the prevention and treatment of the disease.

METHODSWe conducted retrospective statistical analyses on the medical records of 48 outpatients and 21 inpatients with Brucella orchitis.

RESULTSBrucella orchitis was diagnosed in 6.67% of the male patients with brucellosis (69/1 034). The disease exhibited typical epidemiological features, with a higher incidence rate among those in frequent contact with sheep and elderly people, in the period from April to July, and in the areas with sheep husbandry. All the Brucella orchitis patients had such local symptoms as testicular pain and swelling, more frequently involving both testes, and other most common symptoms included fever, chills, sweating, and painful joints. Based on IIEF-5, 45 of the patients suffered from severe erectile dysfunction, with their reproductive function temporarily affected in the course of the disease. Misdiagnosis easily occurred in the early stage of the disease. Therapeutic options mainly included doxycycline hydrochloride and rifampicin, administered orally or intravenously, which could effect a cure, though relapse might occur in some cases.

CONCLUSIONBru- cella orchitis has distinct epidemiological characteristics, with clinical manifestations of testicular pain and swelling. Though a transient disease, it affects the reproductive function of the patient before cured. It can be treated by combined oral and intravenous medication, with painkillers or ice bags for testicular pain and swelling.

INTRODUCTIONBrucellosis is a public health problem that is prevalent in several developing countries.

METHODSThe clinical and laboratory characteristics of 164 cases of brucellosis in Bursa, Turkey, were retrospectively evaluated.

RESULTSThe 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.

CONCLUSIONBrucellosis 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.
