Hoepfully that helps i never thought of just directly copying and pasting stuff..lol this is just the beginning of all there is that I have learned and yes not everyone will have this but if you do have it. It would seem to be a really good indicator that something else is going on.

Thanks for the material! Yes, if you do have this capillary pattern in Raynaud's without being old, or having untreated Primary Raynaud's a very, very long time time, it is cause for concern. I was hoping to find something very current from this research, but didn't see anything much past 2007 or 8. Did I miss something? I found the info about APS also very interesting as the UK seems to be more conscious of this disease than the US.
I was 25yrs old and had been sick for a year already when I started getting bleeds and I started researching I am very lucky to have friends in the medical community that got me on the right path to finding out information if you have any questions i can try and post what stuff I have found to be relevant to what you want to know! The rheumatologist said it was a scleroderma pattern but I have now looked at my own and I'm not exactly convinced I do have the drop outs but my capillaries are very twisted and long and engorged with blood and bleed often so I'm not sure where I stand most docotrs don't understand all of this either
The predictive value of nail fold capillaroscopy in the diagnosis and monitoring of some connective tissue diseases has been definitely established [12]. NVC analysis has proven to be particularly useful in evaluating the progression of sclerodermic microangiopathy [9]. Indeed, different patterns were found to be related with different disease durations in this connective tissue disease. Moreover, cerebral hypoperfusion assessed by 133-xenon fluximetry along with single-photon emission computed tomography analysis has been recently reported to be related to major NVC patterns seen in scleroderma [13]. The relationship between changes induced by the same disease in two microcirculation systems, i.e. brain and skin capillaries, suggests an unexpected opportunity for monitoring the severity of disease by a simple and non-invasive method.
MC is a multiorgan disorder characterized by the malfunction of the reticuloendothelial system with deposition of immune complexes (mostly consisting of a monoclonal IgM directed to an IgG that usually reacts with HCV) at the level of tissue microcirculation [14]. These cryoprecipitable immune complexes have the unique property of accumulating inside the monocytes of affected organs [3] producing a thesaurismosis-like phenomenon [15]. This accumulation is possibly due to abnormalities of the enzymatic assessment of HCV-infected monocytes, which impair intraphagosome degradation of phagocytosed cryoglobulins.
In this study, patients with MC were found to have a variety of microcirculatory changes. Certain vascular abnormalities may be detected in several connective tissue diseases. For instance, the enlargement of the entire capillary loop and loss of blood vessels are observed in patients with dermatomyositis and, even more often, with scleroderma [12]. However, while individually non-specific, the abnormalities detected in MC could be clustered in a pattern of tortuous and short capillaries with abnormal orientations and with neoangiogenetic shapes, which is consistent with a high degree of deterioration of nutritional circulation.
The microcirculatory changes occurring in MC might be related to ischaemic events due either to rheological disturbances (as a consequence of hyperviscosity) or to subclinical perivascular leucocyte infiltration of small- or medium-sized tributary vessels [16]. The angiogenetic phenomena could represent an attempt to compensate for the defective nutritional circulation. This study failed to show significant correlations between NVC abnormalities and patients’ age or disease duration, as has been found for other clinical and biochemical parameters in HCV-infected patients [17]. Somewhat analogous to encephalopatic manifestations in scleroderma, NVC abnormalities in MC have been found to be particularly numerous in the presence of renal involvement, a known factor of worsening prognosis [4]. Additional and differently designed studies are needed to verify if the extent of microangiopathy may be regarded as a predictor of the development of cryoglobulinaemic nephritis. Thus, the apparent association between renal involvement and a greater score of NVC abnormalities must be regarded cautiously. Moreover, attempts to correlate observed NVC changes with histological features were limited by the relatively low number of affected patients. The specificity of the relation to the membranoproliferative pattern of glomerulonephritis could not be verified by examining patients with other types of glomerular involvement, such as membranous or mesangial glomerulonephritis, which can occasionally be detected in these patients [18]. Finally, more obvious parameters of renal involvement, like proteinuria, clearly reflect microcirculatory abnormalities.
Despite these limitations, which will call for a more extensive analysis, definite abnormalities have been detected by NVC in patients with MC, with some prevalence in those presenting with glomerulonephritis.
