Vertebral tuberculosis: a growing concern in London
|
Vertebral tuberculosis: a growing concern in London The incidence of vertebral tuberculosis (TB) in the UK, particularly East London, is increasing. The lower thoracic and upper lumbar vertebrae are the areas most often affected. Vertebral TB usually results from haematogenous spread of TB from other sites, often pulmonary. Then as the infection spreads, it involves the intervertebral disc which then collapses, and replaced by caseation. Presenting the paper, ’Vertrbral tuberculosis in East London: Whistle blowing’, at the Society for Back Pain Research (SBPR) 2007 in Helsinki, Finland, Mr Fras Dakhil-Jerew, reported that in 2005 the London region accounted for a substantial proportion of TB cases (43%) in the UK, and also had the highest rate of disease (46.3 per 100,000). TB has been prevalent in the UK since 1900, and Britons have long blamed the Roman Empire for bringing the disease into the isle as long as the first century AD, explained Dakhil- Jerew. Interestingly, more recently an archaeologist and molecular biologist discovered traces of TB on 2,300-year-old human remains that were unearthed in the 1970s and lay undated until 2001 in a museum in Tarrant Hinton, near England’s southwest coast. Diagnosis of the disease is usually conducted by magnetic resonance imaging (MRI) as well as a knowledge of the patient’s history. However, Dakhil-Jerew explained that diagnostic evaluation of TB is hampered by the difficulty of MRI interpretation and "failing to keep a high index of suspicion." Presently, it seems that the problem is associated with the rise in occurrence of the disease particularly in East London and is due to lack of awareness from physicians and misdiagnosis.

Study Dakhil-Jerew outlined the protocol for a cross sectional study of 123 patients (mean age 34; 55% male, 45% female) with confirmed vertebral TB between the years of 1999-2006, in two London hospitals; The Royal London Hospital and King George Hospital. The mode of presentation, surgical procedures and outcome of patients were highlighted. In the study, Asians represented the highest immigrant group (63%) followed by Afro Caribbean (29.2%), white British (6.6%) and East European (1.6%). It was found that the dorsal spine was the most commonly affected site (45%), followed by the lumbar spine (33%) and multiple spinal regions in 22%. Delayed diagnosis was made in 34% of patients, of which 44% the diagnosis was not established before six months following initial presentation. It was also reported that back pain/neck pain was the presenting complaint in 100% of patients, whereas neurological signs were found in only 37% and systematic manifestations present in 38%. To control the disease, spinal surgical procedures was needed in 44% of cases. Approximately 30% of them had partial recovery and 9% had complete recovery, said Dakhil-Jerew. He added, that from MRI analysis, there was evidence of the following conditions:
_ Discitis (70%) _ Osteomyelitis (83%) _ Abscess or mass (75%) _ Vertebral collapse (30%) _ Vertebral compression (41%) _ Epidural extension (45%) _ Psoas abscess (23%)

Treatment Medical treatment consisted of Rifampicin, Isoniazid, Pyrazinamide, Ethanbutol, and Streptomycin, and surgical indications resulted from vertebral collapse/kyphosis, neurological symptoms, worsening neurology, spinal cord compression, and expanding abscess. The surgical procedures required consisted of: _Drainage 14(11%) _Decompression and fusion 14(11%) _Corpectomy + stabilisation 8(6.5%) _Decompressive laminectomy 7(5.6%) _Laminectomy + fusion 7(5.6%) _CT guided biopsy 4(3.2%) Conclusion In his concluding remarks, Dakhil-Jerew explained that, "The incidence of vertebral TB is on the increase. A high index of suspicion is required to avoid delay in the diagnosis, and a knowledge of the patients’ background may help making appropriate early referral for MRI especially among Asian groups."
