White matter lesions on magnetic resonance imaging and their relationship with vascular risk factors in memory clinic attenders

Abstract: Background The association between white matter lesions on magnetic resonance imaging (MRI) and the presence of vascular risk factors has been investigated in different populations, and results have varied widely. However, this relationship has not been adequately addressed in memory clinic attenders who have relatively early cognitive impairment. Objectives This study was undertaken to determine the relationship between the severity of white matter lesions and vascular risk factors in elderly subjects referred to a Memory Clinic, irrespective of their diagnoses. Patients attending the Memory Clinic had relatively early, mild cognitive impairment and differed, in this respect, from typical unselected community-based samples and from patients with established dementia. The study also investigated whether periventricular and deep white matter lesions differed in their relationship with vascular risk factors. Methods All patients assessed in the Memory Clinic at Leicester General Hospital between April 1998 and October 2000 who had undergone an MRI scan were included in the study. They received a comprehensive clinical and cognitive assessment, a standard dementia laboratory screen and evaluation of vascular risk factors. MRI scans were reviewed by two independent raters and semi-quantitative ratings of the severity of white matter lesions were made using standardised protocols. The relationship between cerebral white matter lesions and vascular risk factor variables was examined by multiple linear regression. Results One hundred and seventy-seven subjects were included in the study. The mean age was 69.8 and the mean MMSE score was 23.2. Of the risk factors investigated, only age and prior cerebrovascular disease were significantly associated with severe periventricular white matter lesions; age, hypertension and diabetes were significantly associated with severe deep white matter lesions. Conclusions Periventricular and deep white matter lesions are differentially influenced by vascular risk factors. Copyright © 2005 John Wiley & Sons, Ltd.

Differential effects of cyclosporin and tacrolimus on the expression of fibrosis-associated genes in isolated glomeruli from renal transplants.

Abstract: Background Chronic allograft nephropathy is characterized by an excessive accumulation of extracellular matrix proteins leading to glomerular and interstitial fibrosis. The aim of this study was to determine the effects of two different immunosuppressive agents (cyclosporin and tacrolimus) on the expression of the genes controlling extracellular matrix deposition in renal transplant glomeruli. Methods Fifty-one renal transplant recipients were randomized to receive immunosuppression with either microemulsion cyclosporin or tacrolimus. Isolated glomeruli were plucked from protocol transplant biopsies performed 1 week, 3 months and 6 months after transplantation. Expression of the genes for collagen IVα2, collagen III, matrix metalloproteinase 2, tissue inhibitor of metalloproteinases (TIMP) 1 and TIMP-2, tenascin and transforming growth factor (TGF) β1 was studied by quantitative reverse transcriptase–polymerase chain reaction. Results The expression of messenger RNA (mRNA) for collagen III and TIMP-1 was significantly higher in patients receiving cyclosporin therapy than in those having tacrolimus (P < 0·01); this finding was accounted for by differences in the biopsy material at 1 week. A significant difference in collagen III, TIMP-1 and TIMP-2 mRNA expression was also detected between patients depending on the source of renal donor (cadaveric or living). There were no significant differences in the level of glomerular TGF-β1. Conclusion The data provide new in vivo evidence that tacrolimus may exert a less fibrogenic influence on transplant glomeruli than cyclosporin. © 2000 British Journal of Surgery Society Ltd

Infertility may sometimes be associated with nsaid consumption

Abstract: Non-steroidal anti-inflammatory drugs are widely used in the treatment of inflammatory joint diseases. Many patients suffering from these disorders are young women during their childbearing years. We report three cases of infertility where the cause may have been NSAID-induced 'luteinized unruptured follicle' syndrome. This phenomenon is well recognized in obstetric circles, and we would like to bring it to the attention of rheumatologists since it is not documented in the rheumatological literature.
