          Abstract

          Brucellosis is an infectious disease, frequently encountered in developing countries. It may involve multiple organ systems of the human body. However, neurobrucellosis is a rare complication of brucellosis. The most frequent events of cranial involvement are meningitis and meningoencephalitis. In the present case, a 10-year-old girl was referred to our clinic with fever, headache, nausea, and vomiting. The patient’s blood and cerebrospinal fluid cultures were found positive for brucellosis. Communicating hydrocephalus was also present in the cranial computed tomography as a complication of neurobrucellosis. The patient was successfully treated by external ventricular drainage and triple antibiotic therapy. There was no need to insert a ventriculo-peritoneal shunt.

          Neurobrucellosis: clinical and therapeutic features.

          Eighteen patients with neurobrucellosis are described. Eleven patients had meningitis alone or with papilledema, optic neuropathy, or radiculopathy. Four patients had meningovascular complications manifested by stroke or intracerebral hemorrhage from a presumed mycotic aneurysm. Two patients had parenchymatous dysfunction, including a child who had a cerebellar syndrome without evidence of direct infection of the central nervous system. One patient presented with polyradiculopathy. Twelve of 16 patients had pleocytosis; none had cell counts greater than 419 x 10(6)/L. Most patients had hypoglycorrhachia and elevated levels of protein in the cerebrospinal fluid (CSF). Results of an agglutination test for Brucella in serum were positive for all patients. Six of 16 patients had positive blood cultures, and four of 14 had positive CSF cultures. Antimicrobial treatment included concurrent administration of two or more of the following drugs: streptomycin, tetracycline (or doxycycline), rifampin, and trimethoprim-sulfamethoxazole. Eleven patients fully recovered. Five patients were left with residual neurological deficits. Four of these patients suffered permanent hearing loss, one of whom also had significant loss of vision in one eye. One elderly senile patient with meningovascular brucellosis remained in a vegetative state despite receiving antimicrobial therapy for 6 months. One patient died due to rupture of a mycotic aneurysm within 7 days of initiation of therapy. One other patient was treated after sustaining an intracerebral hemorrhage, but this patient's condition was diagnosed only after discharge.

            Human brucellosis in Kuwait: a prospective study of 400 cases.

            The clinical pattern of 400 cases of brucellosis in Kuwait is presented. The disease was acute in 77 per cent, sub-acute in 12.5 per cent and chronic in 10.5 per cent of cases. Raw milk was the major source of infection. The major features on presentation, irrespective of the course of the disease, were fever, sweating, headache, rigors, arthralgia, myalgia, and low back pain. Hepatosplenomegaly was present in 41 per cent of cases and in 32 per cent neither liver nor spleen were palpable. The haematologic findings were not specific and hepatic dysfunction (shown by liver enzyme abnormalities) was common. Skeletal (26 per cent) and genital (8.5 per cent) changes and neurobrucellosis (7 per cent) were the major complications. The ELISA was the most sensitive and reliable diagnostic test especially in relation to chronic brucellosis and neurobrucellosis. ELISA allowed the determination of brucella-specific immunoglobulins (Ig)G, IgM and IgA in the CSF, and provided profiles of Ig, in sera, which were different in patients with chronic (elevated IgG and IgA) from those with acute (elevated IgM alone or IgG, IgM and IgA) brucellosis. Treatment with tetracycline, doxycycline or rifampicin gave a cure rate of over 91 per cent in acute and subacute brucellosis. Co-trimoxazole was associated with a relapse rate of 50 per cent. Two drug combinations of streptomycin and tetracycline, streptomycin and rifampicin or streptomycin and doxycycline were effective, but one of five patients with chronic brucellosis relapsed. A combination of streptomycin, tetracycline and rifampicin with or without steroids was used successfully in neurobrucellosis, septicaemic shock and subacute bacterial endocarditis.

              Childhood brucellosis--a microbiological, epidemiological and clinical study.

              A total of 5726 blood specimens (from children aged 14 years and younger) were studied for the serological evidence of brucellosis. Ninety-three (1.6 per cent) showed diagnostic agglutinin titres with a geometric mean titre of 403 (SD +/- 547). Forty-three (59.7 per cent) blood specimens yielded the growth of Brucella melitensis. Thirty-nine patients (41.93 per cent) were shepherds, who constituted the major occupational group affected in the present series. More than 60 per cent of the patients had a history of both consumption of fresh goat's milk and close animal contact. The habit of consuming fresh goat's milk to obtain relief from chronic ailments was noted in nine patients. Seventy-three (78.49 per cent) were males and 20 (21.51 per cent) were females, with a male to female ratio of 3:1. The disease occurred mainly in the school age group (mean age 10.3 years). All the patients had an acute history of less than 2 months. Forty-nine (52.68 per cent) patients presented with persistent fever, 19 (20.43 per cent) with joint pain, and the rest with a combination of fever and joint pain with and without low backache, fever being the commonest complaint. One case presented with involuntary movements of limbs alone and the other with burning feet only. Pityriasis alba was the consistent physical finding, with fever in the majority of the patients. The major joint found to be involved was the knee (52.77 per cent). The synovial fluid obtained from the knee joint of five patients demonstrated Brucella agglutinins and also three grew B. melitensis. Eight patients presented with complications that included skin lesions (3), carditis (2), neurobrucellosis such as chorea (1), peripheral neuritis (1), and meningitis (1). Brucella melitensis biotype 1 was successfully isolated from the papular eruption of one out of three cases who presented with skin lesions. To our knowledge this is the fourth confirmed isolation of B. melitensis from skin lesions with brucellosis, reported in the literature. The cerebrospinal fluid obtained from the meningitis patient was positive for B. agglutinins. To our knowledge chorea of brucellar origin appears to be the first case reported in the literature. In 15 cases (16.13 per cent) brucellosis was suspected clinically whereas 78 (83.87 per cent) cases, only serological evidence of brucellosis confirmed the diagnosis. None of the cases relapsed. In our experience an initial combination therapy with a three-drug regimen followed by a two-drug regimen for a minimum of 6 weeks has been found to be effective in the prevention of a relapse.
