In 75 patients with visceral rheumatism prior to and following antirheumatic treatment the authors studied the REG in a frontomastoidal and occipito-mastoidal leading as well as the REG of the brachial muscles. In one group of patients there were REG signs of a significantly increased tone of the cerebral vessels, especially of the arterioles and veins accompanied by a certain drop of brain repletion. In the other group there was a decrease of the pulse blood repletion of the hemispheres along with a significant drop of the arteriole and venous tone and difficulties in the blood back flow from the brain cavity. In most of the patients in the basin of internal carotid arteries there was a prevalence of arterial ischemia, while in the vertebrobasillar system -- venous hypoxia.

Retinal vascular manifestation is the most common form of ophthalmic involvement in patients with systemic lupus erythematosus (SLE). Most frequently these consist of cotton-wool spots with or without intraretinal hemorrhages. Although rare, a more severe retinal vaso-occlusive disease, termed retinal vasculitis, has been described. We report on a 37-year-old white female with a 13-year follow-up of chronic discoid lupus erythematosus, which suffered massive bilateral visual loss coincident with the systemic exacerbation of her disease (proteinuria, pneumonia, serositis, leucopenia). The diagnosis of SLE was established with reference to the revised ARA-criteria (American Rheumatism Association). Ophthalmoscopy and fluorescein angiography revealed the typical aspect of a SLE-associated vaso-occlusive retinopathy on both eyes with marked ischemia of the macula. Immediate maximal immuno-suppressive therapy, early performed panretinal photocoagulation and subsequent cryoretinopexy did not stop the progression of the disease. Six months after the initial event vascularisations of the disc and rubeosis iridis occurred, but no secondary glaucoma up to date. In this patient, the almost complete absence of characteristic autoantibodies and immunological markers was striking. The correlation with other lupus manifestations, different therapeutic concepts and prognostic factors in SLE-associated retinal vasculitis are discussed.

Between April 1983 and November 1985, 14 patients have undergone a heart transplant, or 10 men and 4 women, aged from 17 to 55 years. The surgical indication was a cardiomyopathy in terminal evolutive phase, of which the etiology was ischemia in 8 cases, congestion in 5 cases and rheumatism in one case. There was one operative death (7.1%) from acute rejection and a late death secondary to chronic rejection. The actuarial rate of survival at one and 2 years was 81.9%. Post-operative complications, most frequent at an early stage, were arterial hypertension (9 cases), rejection (8 cases) and renal insufficiency (6 cases). During an average post-operative evolution of 13 months, 17 rejection episodes occurred in 10 patients (71.4%) and 5 patients (35.7%) presented with 7 infectious episodes, one of them severe. Cyclosporin's toxicity appeared in the immediate post-operative period by an always reversible increase of the bilirubin and creatinin levels. On a long term, all patients present with arterial hypertension, accompanied by a moderate renal insufficiency (creatinin between 2.2 and 2.4 mg%). Among the survivors, 9 patients (75%) remain completely asymptomatic and have resumed normal physical activities. Cardiac transplantation has therefore become a valid therapeutic alternative, able to greatly improve survival and the functional condition of patients with terminal cardiomyopathy.

The modern development of vascular surgery has a real possibility to reduce lethality and the amount of amputations in patients with embolism of the aorta and major arteries of the extremities. An analysis of treatment of 2042 patients during the recent 28 years has shown that the embolism is observed in 62,3% of patients with IHD and its complications, and in 34,5% in rheumatism patients, the arterial impassability prevailing in the abdominal aorta basin and lower extremity arteries (67,5%). Surgical procedures were used in 86,6% with the restoration of the main or collateral blood flow in 91,2% of the patients operated upon. Irreversible ischemia of the extremity was diagnosed in 89 patients at admission to the hospital. For prophylactics of rethromboses and infection, nonmedicamentous methods of treatment played an important role and the amount of rethromboses was reduced to 5,5% and suppuration of the wound to 6,2% which resulted in low percentage of amputations (5,8%).

Heterocyclic indazole derivatives are claimed in patent WO2008138448 as inhibitors of the serum- and glucocorticoid-inducible-kinase 1 (SGK1) and drugs for the pharmacological treatment of SGK1-related diseases, such as diabetes, obesity, metabolic syndrome, systemic and pulmonary hypertension, cardiac fibrosis, hypertrophy and insufficiency, arteriosclerosis, glomerulosclerosis, nephrosclerosis, nephritis, nephropathy, deranged electrolyte excretion, fibrosing and inflammatory disease (e.g., liver cirrhosis, lung fibrosis, rheumatism, arthrosis, Crohn s disease, chronic bronchitis, radiation fibrosis, sclerodermia, cystic fibrosis, scar formation and Alzheimer' disease), tumor growth, peptic ulcers and some disorders hitherto not conclusively shown to involve SGK1. Most of the claims are supported by the literature. SGK1 is ubiquitously expressed and its expression is stimulated by hyperglycemia, cell shrinkage, ischemia, glucocorticoids, mineralocorticoids and several inflammatory mediators including TGF-ss. SGK1 is activated by insulin and growth factors via the phosphatidylinositol-3-kinase pathway. SGK1 regulates ion channels (including ENaC, KCNE1/KCNQ1), carriers (including NCC, NHE3, SGLT1), Na(+)/K(+)-ATPase, enzymes (including glycogen-synthase-kinase-3) and transcription factors (including FOXO3a, ss-catenin, NF-kappaB). A gain-of-function SGK1 gene variant, carried by approximately 3 - 5% of Caucasians and approximately 10% of Africans, is associated with increased blood pressure, obesity and type 2 diabetes. In vitro and in vivo experiments suggested a critical role of SGK1 in renal fluid retention and hypertension, glucose-induced obesity, coagulation and increased matrix protein formation.

Ischemia/reperfusion (I/R) injury can be characterized as an inflammatory response including recruitment of inflammatory cells to a post-ischemic organ or tissue and a cascade of mediators. Sinomenine (SIN), a pure alkaloid extracted from the Chinese medical plant Sinomenium acutum, has been used to treat various inflammatory diseases including rheumatism and arthritis. However, whether SIN can attenuate I/R injury has not previously been examined. Using a syngeneic orthotopic liver transplantation model in rats, we investigated the effect of SIN on hepatic I/R injury, in particular its effect on heme oxygenase-1 (HO-1) induction and its hepatocellular protective effect. To our knowledge, our results were the first to show that: (a) SIN pretreatment was able to induce HO-1 expression in donor livers in a dose dependent manner; (b) SIN pretreatment protected the liver graft from cold I/R injury; and (c) the protective effect of SIN was, at least in part, mediated by HO-1, as proved by the fact that inhibiting HO-1 activity with zinc protoporphyrin (ZnPP) reduced the protection. Thus, SIN deserves further exploration as a novel agent to attenuate I/R injury.
