ABSTRACT

Objective To observe the dynamic serological test results of 28 patients with acute brucellosis,and to investigate the relationship between serological test results and diagnosis,curative effect and prognosis of brucellosis.Methods Twenty eight patients(infected with sheep brucellosis) with acute brucellosis in the Department of Brucellosis in Heilongjiang Provincial Land Reclamation Headquarters General Hospital were selected as research subjects,and their serological changes were tested by means of tube agglutination test (SAT)and clinical outcomes were compared before and after each stage of treatment.In addition,symptoms of fever,weakness,sweating,joint pain,swollen lymph nodes and biochemical parameters [alanine aminotransferase (ALT),lactate dehydrogenase (LDH)] were also tested 3,6 and 9 weeks after the treatment.Results Antibody titer reached the peak at the third week,1 ∶ 400(++),which accounted for 39.29% (11/28); 2857%(8/28) of the patients became negative at the sixth week; 50.00% (14/28) became negative at the ninth week.Before the treatment,20(71.43%) patients had the symptom of fever,8 (28.57%) patients had the symptom of hyperhidrosis,28 (100.00%) patients had the symptom of joint pain,7(25.00%) patients had the symptom of lymph node enlargement,28 (100.00%) patients' ALT was elevated,and 26(92.86%) patients' LDH was elevated.After three weeks of treatment,except the three patients (10.71%) who occasionally had fever,the rest of the patient's temperature was returned to normal.Also the numbers of patients with the symptoms of fatigue,sweating and joint pain were significantly reduced,and specifically,the conesponding number was 13(46.43%),2(7.14%),and 21 (75.00%)patients,respectively.ALT and LDH returned to normal(only one patient's ALT was out of the range).At the sixth week,all the patients' symptoms of fever and hyperhidrosis disappeared.The number of patients with the symptoms of joint pain and lymph node enlargement reduced to 12(42.86%) and 3(10.71%),respectively.The results of biochemical tests(ALT and LDT) returned to normal.At the ninth week,most patients' clinical symptoms disappeared.A few patients still had the symptoms of weakness[2(7.14%)] and joint piin[6(21.43%)].Conclusions After effective treatment,antibody titer of patients decreases rapidly,at the same time,the clinical symptoms improve quickly.There is a parallel relationship between the change of antibody titer and clinical symptoms.It is demonstrated that the appearing time of brucellosis specific antibodies,the ampfitude and speed of change of antibody titers can be used in diagnosis,therapeutic evaluation and prognosis of the disease.

ABSTRACT

Objective To observe the clinical features of brucellosis spondylitis and analyse the reasons for its misdiagnosis,and improve the level of diagnosis and differential diagnosis.Methods Forty-two clinically diagnosed patients with brucellosis spondylitis were studied retrospectively,and these patients were diagnosed and hospitalized in the General Hospital of Heilongjiang Land Reclamation Bureau.Their medical records were analyzed,which included the general information,medical history,clinical symptoms,results of magnetic resonance imaging(MRI) and serum tube agglutination test(SAT) and so on.Results Main clinical symptoms and signs were severe persistent neck,back and leg pain.They also had plate shape low back but without kyphosis.In addition,patients had to keep in one posture because their spinal activity was limited.Also,scoliosis or pelvic tilt and lameness may occur when standing,which were typical symptoms of nerve root compression.Thirteen cases were diagnosed as tuberculosis,accounting for 30.95%(13/42); 6 cases were diagnosed as lumbar disc herniation,accounting for 14.28% (6/42); 2 cases were diagnosed as ankylosing spondylitis,accounting for 4.76% (2/42).Therefore,the total rate of misdiagnosis was 50% (21/42).Abnormal MRI signal intensity can be seen in the pathological vertebrae.Specifically,T1-weighted images (T1WI) showed low signal,T2-weighted images (T2WI) showed high signal,or mixed high and low signal intensity was observed.Vertebral showed wedge deformation without collapse and sequestrum; strip and sheet abnormal signal can also be found within the intervertebral disc.Normal structure disappeared and disc space became narrow.Accordingly,the plane dural sac was compressed to form visible abscess near the spine,but psoas abscess was not found.Patients with positive SAT result accounted for 92.85% (39/42).Conclusion Reasons for misdiagnosis include lack of detailed medical records,atypical clinical symptoms and similar imaging changes and so on.
