Background & objectives:Chronic venous insufficiency (CVI) is a common clinical problem among obese patients. This study was conducted to evaluate the impact of body mass index (BMI) and associated morbidities such as diabetes, hypertension and hypothyroidism on venous disease clinical scores as per Clinical, Etiological, Anatomical, Pathological (CEAP) classification.Methods:In this study, adult patients with BMI more than 30 kg/m2 with signs of CVI were evaluated clinically and by using Duplex ultrasonography of venous system. The patients with C0, C1, C2, C3 and C4, C5, C6 clinical scores in CEAP classification were grouped as lower and higher clinical scores of CVI, respectively.Results:Of the 200 enrolled patients, 147 (73.5%) were males and were associated with higher grades of clinical scores (P=0.051). Superficial venous system was involved in 96 per cent patients and 91 per cent patients had reflux in the sapheno-femoral junction. A negative association was observed between hypertension and male gender (P=0.001). Higher BMI was associated with higher clinical scoring (P=0.053). BMI >40 kg/m2 was associated with primary aetiology (P=0.007) of CVI. There was no correlation between superficial, deep or perforator incompetence with BMI (P=0.506). Duplex-confirmed significant reflux was observed in patients with higher BMI (P=0.006). Age and BMI were positively correlated with clinical score (r=0.176; P=0.013 & r=0.140; P=0.049), respectively.Interpretation & conclusions:Our findings indicated that elderly male patients with high BMI seemed to be at a higher risk of advanced clinical grades of CVI. The impact of comorbid conditions such as diabetes, hypertension and hypothyroidism on CVI could not reach at significance in the present study.
Patients with chronic renal failure, especially those on long-term hemodialysis (HD), have a high incidence of premature cardiovascular disease. Oxidative stress, which occurs when there is an excessive free radical production or low antioxidant level, has recently been implicated as a causative factor in atherogenesis. Hourly changes in malondialdehyde (MDA) and antioxidant enzymes, vitamins, lipid profile and ferric reducing ability of plasma (FRAP) were studied with the first use and immediate subsequent reuse of polysulfone dialysis membrane in 27 patients on regular HD treatment. Data were corrected for hemoconcentration and standardized to measure the rate of change. Increase in MDA and erythrocyte catalase along with decrease in plasma vitamin E and FRAP levels and no change in glutathione peroxidase levels were observed as a result of both fresh and reuse dialysis. These findings indicate a net oxidative stress in both fresh as well as dialyzer reuse sessions. There was no significant change in oxidative stress in both fresh and reuse sessions. The oxidative stress with reuse dialysis was less when compared to first use dialysis, but the difference was not statistically significant.
Leptospirosis is an important zoonosis with a worldwide distribution that is characterized by a broad spectrum of clinical manifestations ranging from inapparent infection to fulminant disease. The presentation of paraparesis in combination with acute renal failure is rare.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
