In a prospective study of 102 outpatients with histologically proven lung cancer, the prevalence and prognostic significance of microalbuminuria (urinary albumin excretion > 20 micrograms/min) were analysed. 65 consecutive outpatients with benign lung disorders served as controls. An immunoturbidimetric assay, sensitive at low concentrations, was used to quantify the albumin excretion rate in timed overnight urine samples. Patients with malignancies had a significantly higher frequency of microalbuminuria (32.4% compared with controls, 13.8%, P < 0.01) and median urinary albumin excretion rate (13.4 versus controls, 8.9 micrograms/min, P < 0.003). Urinary albumin excretion was significantly higher in lung cancer patients with TNM stage III and IV. Patients with malignancies and microalbuminuria had a significantly lower survival rate than patients with normoalbuminuria (probability of survival 1 and 3 years after diagnosis 66% and 16% versus controls, 22% and 4%, P < 0.00001). In a multivariate model, which adjusted for age, sex, performance status, histological type and TNM stage, microalbuminuria continued to be a significant predictor of survival. In conclusion, an increased prevalence of microalbuminuria has been demonstrated in patients with lung cancer. The presence of microalbuminuria was associated with advanced disease stage and poor survival.

This paper examines the pathogenesis, epidemiology and risk of cardiovascular disease due to smoking and oral contraceptive (OC) use among women. The major risks associated with smoking were cardiovascular diseases and lung cancer. Characteristics of a syndrome which significantly increases the cardiovascular disease risk include: waist/hip girth ratio 0.8, glucose concentration 100 mg/dl, insulin 25 mU/l, peptide C 1.3 nmol/l, blood pressure 135/85 mm Hg, high triglyceride level 150 mg/dl with low concentration of HDL cholesterol (45 mg/d), total cholesterol/HDL ratio 4.0, LDL cholesterol (small dense pattern B) 130 mg/dl, uric acid concentration 7 mg/dl, and microalbuminuria 30-200 mg/dl. Women users over age 35 carrying the coagulation factor V Leiden mutation were found to be at increased risk of death from cardiovascular disease. The study indicates that increasing the estrogen dosage in an OC from 20 to 50 mcg ethinyl estradiol produced greater risks. Most cardiovascular disease among OC users is due to thrombosis. OCs containing the third-generation progestins desogestrel and gestodene have been associated with greater risks of venous thromboembolism that are associated with older progestins, although there is some controversy surrounding these findings. Smokers must be discouraged. When middle-aged women stopped smoking, about a third of their excess risk for coronary heart disease was eliminated within 2 years of cessation, and their risk became similar to that of nonsmoking women within 10-14 years.

Autosomal-dominant polycystic kidney disease (ADPKD) is a systemic disease with multiple extrarenal manifestations. It accounts for 7% to 11% of patients receiving dialysis or renal transplantation (RT) for end-stage renal disease (ESRD) in Europe. We analyzed retrospectively the causes of death, the prevalence of cardiovascular risk factors (CVRF) and the patient and graft survivals in 62 consecutive ADPKD patients who received 63 cadaveric grafts (29 men and 34 women), of the 600 RTs performed between 1980-2001. The diagnosis of ADPKD was established by family history and ultrasound techniques. At present, 50 patients (79.4%) have functioning grafts, with a mean follow-up of 84.7 months (range, 12-255), and 13 patients have lost their grafts. The main cause of failure was patient death with a functioning graft (9 cases). Malignancies occurred in 5 patients, including 2 lymphomas, 1 renal carcinoma, 1 pancreas sarcoma, and 1 lung cancer associated with infection. Three patients died of cardiocerebrovascular events, and 1 patient of pneumonia. One patient lost the graft after decreasing the immunosuppression for an obstructing colon cancer. Three additional patients now on dialysis lost their grafts due to chronic rejection in 2 cases and primary nonfunction in 1 case. The prevalence of cardiovascular risk factors among the 50 patients with functional grafts were: hypertension, 70%; hypercholesterolemia, 62%; hyperhomocysteinemia, 30%; hyperfibrinogenemia, 68%; increased lipoprotein (a), 18%; microalbuminuria, 22%; hyperuricemia, 48%; hyperparathyroidism, 24%; overweight status, 24%; and nonlethal myocardial infarction, 10%. We conclude that ADPKD patients have good graft and patient survivals, and that the presence of malignancy is the main cause of death and graft failure at our center.
