[Non-tuberculous spondylodiscitis. Multicenter study of 19 cases]

Abstract

19 patients diagnosed as non-tuberculous infectious spondylodiscitis (NTIS) have been studied retrospectively over the last 10 years in three general hospitals. The etiology of 13 cases was confirmed (there were nine cases of Staphylococcus aureus, two of Brucella, one of Pseudomonas aeruginosa and another of Salmonella typhi), and the diagnosis of the remaining cases was based on clinical and radiological data as well as on the evolution with antibiotic treatment. The age of the majority of these patients ranged between 40 and 60 years (p less than 0.05), showing a clear predominance of males (p less than 0.05). The most frequently appearing symptom at the beginning of the disease was local pain which was observed in nine patients; the rest presented mixed symptoms which led to misdiagnosis at admission; an exploratory laparotomy was carried out in one patient. The interval from the symptoms' onset to diagnosis ranged between two and sixteen weeks, with an average of 6.8 weeks. The VSG had values between 22 and 148 mm during the first hour, with an average of 83.3 mm. Seven patients underwent surgery, six of them presenting paraparesis-paraplegia, while another presented cervical spondylodiscitis. One patient passed away, two persisted with paraparesis-paraplegia as an irreversible sequela and one with persistent local pain.
