We describe a patient with gastric cancer and membranous glomerulonephritis (MGN). The patient, a 61-year-old male, was admitted to our Hospital in May, 1996, because of proteinuria and hyperlipidemia persisting for a year. Laboratory examination filled the criteria of nephrotic syndrome and renal biopsy revealed MGN of stage II. Prednisolone therapy (40 mg/day p.o.) was started, followed by a gradual decrease in proteinuria from 4.5 g/day to 0.1 g/day. Endoscopic examination was performed because of stomach-ache revealed advanced gastric cancer of Borrmann 4. Desiring for a conservative therapy, he was discharged and moved to a hospice. In literature review, MGN is the most frequent lesion among various glomerular diseases associated with malignancy, such as the lung, stomach, and colon, particularly at an elderly ages, and sometimes antedates the detection of malignancy, as in the present case. In several cases with MGN, immune-complexes composed of tumor antigens, such as carcino-embryonic antigen, and antibodies have been reported to deposit in basement membrane of glomeruli, causing MGN. In the renal and gastric cancer tissues of the present case, the presence of three novel tumor-associated antigens, Span-1, Thomsen-Friedenreich antigen (T antigen) and F1 alpha antigen, was examined, using a immuno-peroxidase method. Although none of these three antigens were immuno-stained in the renal tissue, clinical course and literature review suggest that MGN in this patient seems to be associated with gastric cancer, which may have produced MGN-causing tumor antigens other than the three antigens. It should be emphasized that malignancy should be carefully and routinely examined in patients with MGN, particularly at elderly ages.

To investigate the role of selected medical conditions on the risk of ovarian cancer, we analysed data from a case-control study. Cases were 971 women below the age of 75 years with histologically confirmed epithelial ovarian cancer, admitted to a network of hospitals including the major teaching and general hospitals in the greater Milan area. Controls were 2758 women admitted to the same network of hospitals for acute, non-gynaecological, non-hormone related, non-neoplastic conditions. Obesity/severe overweight were inversely associated with the risk of ovarian cancer (multivariate relative risk, RR, 0.66, 95% confidence interval, CI, 0.52-0.85). Hyperlipidaemia was also inversely related to ovarian cancer risk, (RR 0.64, 95% CI 0.45-0.89). No relationship emerged between ovarian cancer risk and diabetes (RR 0.80, 95% CI 0.54-1.19), hypertension (RR 0.85, 95% CI 0.68-1.06), thyroid diseases (RR 0.89, 95% CI 0.63-1.13) and cholelithiasis (RR 0.86, 95% CI 0.66-1.12). A decreased frequency of ovarian cancer was seen in women with a history of uterine leiomyomas (RR 0.66, 95% CI 0.47-0.92) and benign ovarian cysts (RR 0.69, 95% CI 0.41-1.13).

A variety of medical, surgical, social, and psychiatric problems affect the renal allograft rejection, thromboembolic disease, infectious events and gastrointestinal disorders. Hypertension and hyperlipidemia appear around 3 months and may remain throughout the posttransplant period. The late complication are atherosclerotic cardiovascular disease, malignancy hepatic failure, chronic rejection, denovo and recurrent renal disease, posttransplant diabetes, musculoskeletal problems, cataracts and skin lesions. Routine follow up of all transplanted patients at specialized centers is critical for early detection and management of these complications. Such practice would reduce the patient morbidity and mortality and lead to an improved long-term outcome.

Dietary fatty acids specifically modulate the onset and progression of various diseases, including cancer, atherogenesis, hyperlipidaemia, insulin resistances and hypertension, as well as blood coagulability and fibrinolytic defects; their effects depend on their chain length and degree of saturation. Hepatocyte nuclear factor-4alpha (HNF-4alpha) is an orphan transcription factor of the superfamily of nuclear receptors and controls the expression of genes that govern the pathogenesis and course of some of these diseases. Here we show that long-chain fatty acids directly modulate the transcriptional activity of HNF-4alpha by binding as their acyl-CoA thioesters to the ligand-binding domain of HNF-4alpha. This binding may shift the oligomeric-dimeric equilibrium of HNF-4alpha or may modulate the affinity of HNF-4alpha for its cognate promoter element, resulting in either activation or inhibition of HNF-4alpha transcriptional activity as a function of chain length and the degree of saturation of the fatty acyl-CoA ligands. In addition to their roles as substrates to yield energy, as an energy store, or as constituents of membrane phospholipids, dietary fatty acids may affect the course of a disease by modulating the expression of HNF-4alpha-controlled genes.

Glucose stabilizes the mRNA for human fatty acid synthase (FAS), an enzyme relevant to diverse human disorders, including hyperlipidemia, obesity, and malignancy. To determine the underlying mechanisms, RNA gel mobility shift assays were used to demonstrate that human Hep G2 cells contain a cytoplasmic factor that binds specifically to the 3'-terminus of the human FAS mRNA. D-Glucose increased RNA-binding activity by 2.02-fold (P = 0.0033), with activity peaking 3 h after glucose feeding. Boiling or treatment of extracts with proteinase K abolished binding. Ultraviolet cross-linking of the FAS mRNA-binding factor followed by SDS-PAGE resolved a proteinase K-sensitive band with an apparent molecular mass of 178 +/- 7 kDa. The protein was purified to homogeneity using nondenaturing polyacrylamide gels as an affinity matrix. Acid phosphatase treatment of the protein prevented binding to the FAS mRNA, but binding activity was unaffected by modification of sulfhydryl groups and was not Mg2+ or Ca2+ dependent. Deletion and RNase T1 mapping localized the binding site of the protein to 37 nucleotides characterized by the repetitive motif ACCCC and found within the first 65 bases of the 3'-UTR. Hybridization of the FAS transcript with an oligonucleotide antisense to this sequence abolished binding. These findings indicate that a 178-kDa glucose-inducible phosphoprotein binds to an (ACCCC)n-containing sequence in the 3'-UTR of the FAS mRNA within the same time frame that glucose stabilizes the FAS message. This protein may participate in the posttranscriptional control of FAS gene expression.

Despite the high rates of rejection, allograft failure, and patient death in the early years of renal transplantation, some patients have done remarkably well. Forty-three (17 living related donor and 26 cadaver donor recipients) such patients with an allograft that functioned for 19 years or more (range, 19 to 29 years) were followed up at this center. The patients included 24 men and 19 women, with a mean age at transplantation of 29 years, of whom 39 were white and four were black. At most recent follow-up, the mean daily dose of azathioprine was 104 mg (range, 50 to 175 mg) and that of prednisone was 10 mg (range, 5 to 20 mg). Mean serum creatinine level was 1.6 mg/dL (range, 0.7 to 5.4 mg/dL). Acute rejection occurred in 14 (33%) patients. Nine patients had one episode and five patients had two episodes of acute rejection. Long-term risks to the recipients appeared in the form of coronary artery disease in 10 (23%) patients; malignancy in 13 (30%) patients, which included nine patients with skin malignancy; and chronic hepatitis C virus (HCV) infection in four patients, two of whom died of complications of liver failure. Other complications included avascular bone necrosis in five patients, which required total hip replacement in two patients; hyperlipidemia requiring treatment in 16 (37%) patients; posttransplantation diabetes mellitus in 10 (23%) patients after a median of 17.5 years (range, 1 to 23 years); and hypertension in 23 (53%) patients. There were seven deaths (three of coronary artery disease, two of liver failure, one each of sepsis and malignancy) and eight graft losses (five to death with function, two to chronic rejection, and one to focal and segmental glomerulosclerosis). Although long-term allograft success results in patients receiving minimal amounts of immunosuppression and having good renal function, long-term renal transplant survivors are at risk for significant morbidity even in the third decade posttransplantation.

Sedentary lifestyle has officially been recognized as a major risk factor for cardiovascular disease. In addition, exercise can be beneficial in detecting, preventing, and managing prevalent disease states such as hyperlipidemia, hypertension, obesity, nicotine addiction, diabetes mellitus, affective disorders, cancer, osteoporosis, and age-related declines in muscular strength. Recent findings are discussed and recommendations for appropriate exercise prescriptions are offered.

Cordyceps sinensis (Berk.) Sacc. is a time-honored tonic food and herbal medicine in China, where recent research has shown that many of its traditional uses may be viewed from the basis of pharmacological activities. The ongoing exploration of C. sinensis in its wild form and cultured, fermented mycelial products derived from it, are reviewed from English and Chinese literature. Part II concludes the series with a review of C. sinensis in preclinical in vitro and in vivo studies, and open-label and double-blinded clinical trials on the respiratory, renal, hepatic, cardiovascular, immunologic, and nervous systems, and its effects on cancer, glucose metabolism, inflammatory conditions, and toxicological studies. In Part I, which appeared in the Fall 1998 issue of this journal (4(3):289-303), we discussed the effects of C. sinensis on antisenescence, endocrine and sexual functions, atherosclerosis, hyperlipidemia, and free radicals.

To investigate the possible role of previous medical history and previous medications as risk factors for hairy cell leukaemia (HCL) we performed a population based case-control study on 121 male HCL patients and 484 controls. The data were collected through a self-administered mailed questionnaire. Elevated odds ratios (OR) were found for a history of appendicitis [OR 1.9; 95% confidence interval (CI) 0.9-4.2] and pneumonia (OR 2.9; CI 0.9-9.6). We found a reduced risk for HCL associated with a history of myocardial infarction (OR 0.3; CI 0.4-2.5), hypertension (OR 0.6; CI 0.3-1.2) and thromboembolic disease (OR 0.6; CI 0.1-2.7). Reduced OR was also associated to a history of diabetes mellitus (OR 0.6; CI 0.1-2.9) and a diagnosis of hyperlipidemia (OR 0.8; CI 0.2-3.6). HCL is an indolent disease with a clinical course of many years and it can not be excluded that the disease leads to metabolic changes, resulting in a changed risk for these diagnoses. When the role of previous medications were investigated, increased OR was found for NSAID (OR 3.4; CI 1.1-10.2). Decreased OR was found for the anti-coagulative agent warfarin (OR 0.4; CI 0.1-1.5). A history of a previous malignancy preceeding the diagnosis of HCL as reported to the Swedish Cancer Registry yielded an increased OR of 3.2 (CI 1.2-8.5). All results must be interpreted with caution, as there is a possibility of misclassification. Medications is difficults to remember, particularly several years after consumption. As many comparisons were made, there is always a possibility of correlations occuring by chance.

Unsafe and potentially safe herbal therapies are discussed. The use of herbal therapies is on the rise in the United States, but most pharmacists are not adequately prepared educationally to meet patients' requests for information on herbal products. Pharmacists must also cope with an environment in which there is relatively little regulation of herbal therapies by FDA. Many herbs have been identified as unsafe, including borage, calamus, coltsfoot, comfrey, life root, sassafras, chaparral, germander, licorice, and ma huang. Potentially safe herbs include feverfew, garlic, ginkgo, Asian ginseng, saw palmetto, St. John's wort, and valerian. Clinical trials have been used to evaluate feverfew for migraine prevention and rheumatoid arthritis; garlic for hypertension, hyperlipidemia, and infections; ginkgo for circulatory disturbances and dementia; ginseng for fatigue and cancer prevention; and saw palmetto for benign prostatic hyperplasia. Also studied in formal trials have been St. John's wort for depression and valerian for insomnia. The clinical trial results are suggestive of efficacy of some herbal therapies for some conditions. German Commission E, a regulatory body that evaluates the safety and efficacy of herbs on the basis of clinical trials, cases, and other scientific literature, has established indications and dosage recommendations for many herbal therapies. Pharmacists have a responsibility to educate themselves about herbal therapies in order to help patients discern the facts from the fiction, avoid harm, and gain what benefits may be available.
