RESUMEN
OBJECTIVES: The morbidity and mortality of patients with rheumatic diseases has improved considerably following the use of biologic therapies. However, an increase in the frequency of bacterial infections has been observed in patients receiving these drugs. In the present study we aimed to establish the incidence and clinical manifestations of non-typhi Salmonella infection in a large cohort of patients with rheumatic diseases undergoing TNF-alpha antagonist therapy due to severe rheumatic diseases refractory to conventional therapies. METHODS: The rate of non-typhi Salmonella infection found in the Spanish Registry of Adverse Events of Biological Therapies in Rheumatic Diseases (BIOBADASER) was compared with that observed in a cohort of rheumatoid arthritis (RA) patients from the EMECAR (Morbidity and Clinical Expression of Rheumatoid Arthritis) Study, who were not treated with TNF-alpha antagonists. The rate found in the BIOBADASER registry was also compared with that available in a non-RA historic control cohort reported in a population from Huesca (Northern Spain). RESULTS: Seventeen cases of non-typhi Salmonella infection were observed in the series of patients exposed to anti-TNF-alpha therapies. The incidence rate of non-typhi Salmonella in BIOBADASER was 0.73 per 1000 patient-years (95% confidence interval [CI]: 0.45-1.17). The incidence rate in the EMECAR cohort was 0.44 per 1000 patient-years. The relative risk for non-typhi salmonellosis in RA patients exposed to TNF-alpha inhibitors compared to those not treated with biological therapies was 2.07 (95% CI: 0.27-15.73) (p=0.480) whereas the relative risk of non-typhi Salmonella infections in patients with rheumatic diseases undergoing TNF-alpha antagonist therapy compared with the non-RA Spanish control cohort was 0.63 (95% CI: 0.38-1.04) (p=0.07). Nine of the 17 patients with non-typhi salmonellosis presented a severe systemic infection. CONCLUSION: Incidence of non-typhi Salmonella infection is not increased significantly in rheumatic patients undergoing anti-TNF-alpha therapy when compared with RA patients undergoing conventional DMARD therapy or with the general population. Nevertheless, at least 50% of patients on TNF-alpha have severe complications once they develop non-typhi Salmonella infection. This fact suggests that anti-TNF-alpha therapies may predispose to salmonella dissemination rather than to infection.

The aim of this study was to evaluate the clinical features, evolution and reliability of spondyloarthropathy criteria in a subset of patients with subclinical sacroiliitis and inflammatory bowel disease (IBD). All patients with IBD (n 62) attending a gastroenterology clinic from a referral centre were included to assess the prevalence of articular involvement. Patients were evaluated according to a specific protocol designed for the study, which included epidemiological and clinical variables, physical examination and radiological assessment. Only those with subclinical sacroiliitis were followed prospectively for 4 years. This group was visited every 6 months with the same initial protocol. Sacroiliac joints were studied using frontal and oblique X-ray views and graded according to New York criteria. HLA B27 typing was performed by serological methods in all patients and in 80 healthy controls. The reliability of Amor and ESSG criteria for spondyloarthropathy was evaluated. Fifteen patients (24%) presented with isolated subclinical sacroiliitis. In this group a higher frequency of peripheral arthritis and erythema nodosum was observed (p = NS compared to those without sacroiliitis). Most cases (60%) were grade II unilateral sacroiliitis. Three patients were HLA B27+ (p>0.05 compared to healthy controls). The resultant sensitivity of Amor's and ESSG criteria ranged from 40% to 46%. An unexpectedly high freuqency (9.5%) of psoriasis was observed in the whole group. There is a high prevalence of isolated subclinical sacroiliitis in IBD. This may represent a forme fruste of enteropathic ankylosing spondylitis, a stunted form of axial involvement because of therapy, or a third category of rheumatic disease associated with IBD. It may also represent a common characteristic of spondyloarthropathies, rather than a specific finding of IBD. The recently developed spondyloarthropathy criteria are not particularly helpful for the diagnosis of this milder form of spondyloarthropathy.

Between 1988 and 1995, 1832 HIV positive patients were evaluated in our institution. We studied the epidemiologic, immunologic and bacteriologic data, laboratory tests, and X-Ray films in those with musculoskeletal infection. We reviewed twenty-one cases of musculoskeletal infection in twenty patients aged 23-35 years (mean 28,6 years, M:F= 15:5). In all of them risk factor for HIV was intravenous drug abuse. The number of CD4 positive lymphocytes ranged from 0,003 to 0,5 10(9)/l. Staphylococcus aureus was the organism responsible of the infection in twelve cases, all active intravenous drug abusers at the time the diagnosis was done. The remaining causative agents were: Mycobacterium tuberculosis (3 cases), Candida albicans (2 cases), Salmonella subgroup 1 (1 case), Neisseria gonorrhoeae (1 case), Pseudomona aeruginosa (1 case) and Streptococcus agalactiae (1 case). Fifteen infections were diagnosed between 1988 and 1991 and 6 between 1992 and 1995. Musculoskeletal infectious lesions in HIV positive patients in our country are related in the majority of cases to intravenous drug abuse. In the last four years due to a National medical health care plan conducted to educate this group of people the number of musculoskeletal infections is decreasing.

Osseous lesions have been reported in only 1-2% of patients with hydatid disease. Joint involvement is usually due to secondary extension from the adjacent bone, although primary hydatid synovitis after haematogenous spread of the infection can be seen. We present a long-term radiological follow-up (12 yr) in a patient who developed hydatid disease of the left pelvic and femoral bones with cartilage destruction of the ipsilateral hip joint. After a Girdlestone arthroplasty, she received mebendazole (3 g/day) for 10 yr and albendazole (400 mg/day) for 2 yr with radiological impairment of the lesions. Complete surgical excision is the treatment of choice for osseous hydatid disease. Isolated medical therapy with mebendazole or albendazole is not adequate for controlling the process, but it can be added to surgery or, as in our case, used like isolated therapy when complete excision is not possible.
