We conducted a prospective, noncomparative, multicenter study to assess the safety and efficacy of doxycycline and netilmicin in the treatment of human brucellosis. The study included 64 patients who had acute brucellosis without endocarditis or neurobrucellosis. The treatment schedule consisted of the administration of 100 mg of doxycycline (or 5 mg/[kg.d] if body weight < or = 40 kg) twice a day orally for 45 days, plus 300 mg of netilmicin (6 mg/[kg.d] if body weight < or = 50 kg) intramuscularly once daily for 7 days. Therapeutic failure was noted in 5 patients (7.7%; 95% confidence interval [CI], 2.5%-17.1%), of whom 2 had spondylitis, 1 had sacroiliitis, and 1 had a splenic abscess that required splenectomy. Relapse was noted in eight patients (12.5%; 95% CI, 5.6%-23.2%). When relapse was considered in combination with initial lack of efficacy, 13 patients (21.9%; 95% CI, 12.3%-33.9%) failed to respond to therapy. Fifteen patients (23%; 95% CI, 13.5%-35.2%) had adverse effects, and one patient (1.5%) had a treatment-limiting adverse effect. Combination therapy with netilmicin/doxycycline may be effective in treating acute brucellosis. However, prospective controlled trials must confirm these results.

The epidemiological features and clinical manifestations of adult cases of brucellosis admitted to the Department of Infectious Diseases, Babol Medical University, Iran from 1997 to 2002 were investigated. Of 469 cases, 267 (56.9%) were males. The mean age of cases was 36.9 +/- 15 years. Most (60.8%) were from rural areas. Two thirds of cases (306, 66.3%) presented during spring or summer. Fresh cheese (22.4%), animal husbandry (11.3%), laboratory worker (8.1%) and veterinary profession (1.5%) were the main risk factors. Forty-five families (9.6%) had two cases. Sweating, fever, and arthralgia were the most frequent clinical symptoms. Complications were documented in 105 males (39.5%) and 41 females (20.3%, P=0.0001). Peripheral arthritis was seen in 24 (9%) males and 19 (9.4%) females, with knees and hips being the most common sites of infection. Sacroiliitis and spondylitis were seen in 28 (6%) and 32 (6.8%) cases respectively with spondylitis more common in males (P=0.023). Epididymo-orchitis was seen in 29 (10.9%) males. There were three cases each of endocarditis (0.6%) and neurological complications (0.6%). Most patients with brucellosis did not have any of the known risk factors for brucellosis. Thus consumption of unsafe dairy products could be the main route of infection. The disease manifested with a diversity of clinical manifestations and complications. Complications were more frequent in males than females.

Patients with infective endocarditis (IE) often have renal complications which may include infarcts, abscesses and glomerulonephritis (GN). Furthermore, it is generally accepted that there is an association between IE and anti-neutrophil cytoplasmic antibody (ANCA). Here, we report the case of a 24-year-old man who developed rapidly progressive GN in the course of IE due to infection with alpha-streptococcus. The initial clinical manifestation of the condition was severe sacroiliitis without fever. Sandwich ELISA showed that the patient was positive for PR3-ANCA at low titer, and the classical complement pathway was also activated. Renal biopsy demonstrated several lesions: focal embolic GN, GN with immune deposits and focal and segmental crescentic necrotizing GN. Treatment with antibiotics and steroids led to eradication of the infection, and resolution of the renal disease was accompanied by immediate disappearance of PR3-ANCA and hypocomplementemia. During a 4-year follow-up period, no recurrence was observed. There have only been 7 case reports of GN associated with IE and PR3-ANCA in which the renal pathology has been described, and the current report is the first to document renal pathology in a patient with isolated pulmonic valve IE and PR3-ANCA. Moreover, this report is the first to show a change in renal biopsy findings in response to treatment. A review of the 7 literature cases and that of our patient showed that none involved pauci-immune GN. Hence, further studies are needed to clarify the prevalence of pauci-immune GN in ANCA-positive IE patients.

Group B streptococcal bacteremia with septic arthritis is a rare complication of second trimester dilation and evacuation, and may cause substantial post-operative morbidity. A 37-year-old gravida 4 para 1-0-2-1 presented with fever and right hip pain on post-operative day 11 from a second trimester dilation and evacuation for fetal trisomy 21. She was initially found to have septic arthritis involving the right sacroiliac joint and group B streptococcal bacteremia. Transesophageal echocardiogram showed a tricuspid valve, vegetation consistent with endocarditis. After prolonged parenteral antibiotic therapy, she developed septic pulmonary emboli that were successfully treated with anticoagulation therapy. Group B streptococcal infection is a potentially serious post-abortion complication that can cause sacroiliitis, endocarditis and septic pulmonary emboli.

Septic arthritis is an orthopedic emergency that is commonly caused by Staphylococcus aureus. Old age, diabetes mellitus, rheumatoid arthritis, prosthetic joint, and recent surgery are the main predisposing risk factors. Most cases of septic arthritis are caused by hematogenous spread of infection. Infectious sacroiliitis is a rare form of septic arthritis which is often clinically challenging to diagnose due its various and nonspecific presentations. Streptococcus mitis belongs to viridans group streptococci (VGS) bacteria, which is a component of body flora that is commonly involved in bacterial endocarditis. VGS in general and S. mitis specifically is an uncommon cause of osteoarticular infections. Here, we report a case of spontaneous Streptococcus mitis bacteremia complicated by septic sacroiliitis in a healthy teenager in the absence of infective endocarditis or a clear source of bacteremia.
