This is the largest study of RA-ILD in the UK. Anti-CCP antibodies were strongly associated with RA-ILD in both sexes. Smoking was strongly associated with ILD in males, which may explain the higher frequency of RA-ILD in men. The predominant HRCT pattern was UIP and most patients had limited disease at presentation. The presence of UIP and extensive disease are associated with increased mortality. Baseline gas transfer is a useful screening tool for ILD, while the preservation of VC at baseline might predict limited disease on HRCT.

-The modified early warning score (MEWS) was developed as a track and trigger tool for the prompt identification of seriously ill patients on an acute medical ward. This paper examines its value in the setting of an acute medical admissions unit (MAU) and compares it to biochemical markers of acute and chronic disease. Three hundred unselected acute admissions to the MAU of the Queen Elizabeth Hospital, Gateshead, were assessed. Correlations between MEWS score and C-reactive protein (CRP) and albumin separately were assessed, and then the relationship between MEWS and the CRP/albumin ratio across the age spectrum was examined. The findings demonstrated a strong correlation between the MEWS score and CRP/albumin ratio (r=0.88, p<0.001) across the whole age spectrum. Length of stay correlated poorly with MEWS (r=0.08) and CRP/albumin ratio (r=0.15). Overall mortality was 5% and was predicted by both tools, with a MEWS score of >4 (relative risk (RR)=7.8) outperforming a CRP/albumin of >2 (RR=2.6). MEWS remains the gold standard for assessing outcome in acute medical admissions, but does have limitations in the elderly (those aged over 70 years). A raised CRP/albumin ratio was less sensitive for overall mortality than MEWS. It did, however, appear to be of greater value in the elderly, especially in those with acute exacerbations of chronic disease. Neither test accurately predicted length of stay.KEY WORDS: albumin, C-reactive protein, death, early warning system, length of stay, outcome

This long term follow up of lung disease in primary SS is reassuring, and suggests that most patients do not develop progressive lung disease. Pulmonary disease occurs predominantly in anti-Ro antibody positive patients and presents early in the course of the disease.

We performed high resolution computed tomography (HRCT) on the lungs of 20 patients with RA and clinical and radiological evidence of interstitial lung disease (ILD). A case control group of patients with RA but without evidence of ILD were similarly studied and all patients underwent detailed pulmonary function testing. Clinical findings, drug therapy, smoking status, the presence/absence of SS and disease activity were also assessed. HRCT showed a range of abnormalities among patients thought to have ILD. Interstitial fibrosis was confirmed in 16 but was frequently associated with emphysema. Ground glass opacification was present in seven, while basal honey-combing was also evident in seven patients. Both these features were present in two patients with ILD. Bronchiectasis was identified in six patients and was the predominant finding in two patients previously thought to have ILD. Among the control patients, HRCT was normal in only five. Clinically unsuspected ILD was present in four patients, while a further four had bronchiectasis. Pleural disease was identified in seven controls. Pulmonary function tests were generally poor predictors of HRCT findings, although a reduced residual volume (RV) [> 1 S.D.] was 83% specific for the presence of ILD and a raised RV [> 1 S.D.] was 64% specific for emphysema. Smoking did not correlate with the presence of either ILD or emphysema and there were no correlations between disease activity and HRCT findings. RA patients with evidence of ILD have abnormalities on HRCT which cannot be confidently predicted on any other non-invasive test.(ABSTRACT TRUNCATED AT 250 WORDS)
