Although the effects of androgen deficiency in the immune system have long been appreciated, little is known about the immunological features of patients with Klinefelter's syndrome (KS). On the other hand, interest in androgens as a possible treatment for some autoimmune diseases is growing. In the present study, some immunological parameters were(More)
Hepatitis B virus (HBV) infection is the leading cause of chronic hepatitis and cirrhosis in Turkey. The prevalence of hepatitis B surface antigen (HBsAg) positivity in Turkey is 5 to 10%. HBV is almost completely preventable with the use of hepatitis B vaccines. The most commonly used vaccine is that which contains the predominant viral surface (S)(More)
It is known that prostate specific antigen (PSA) is strongly androgen dependent, but little is known about the effects of gonadotropin and testosterone treatments on the prostate and serum PSA levels in male hypogonadism. We have therefore determined serum PSA levels before and 3 months after treatment in 13 patients with idiopathic hypogonadotropic(More)
Because of the organ shortage, the number of patients awaiting kidney transplantation has increased rapidly requiring physicians to implement new methods to increase the number of grafts. In this study, we compared clinical and biochemical parameters of patients who received kidneys from hepatitis B surface antigen-positive (group 1) versus other living(More)
Familial Mediterranean fever (FMF) is an autosomal recessive disease. Although the possibility of multiple immunologic mechanisms have been studied, the actual mechanism is still unresolved. Forty-one patients with FMF (24 males and 17 females with a mean age and disease duration of 17.8 +/- 4.1 and 4.7 +/- 2.3 years, respectively) and 14 healthy controls(More)
OBJECTIVE Paired-exchange kidney transplantation (PETx) gains an importance because it is difficult to find suitable organs. The aim of this study was to compare biochemical and clinical parameters of PETx with those of living-related kidney transplantation (LRTx). METHOD The 57 PETx included 18 female and 39 male recipients among 1081 LRTx in 360 females(More)
Although a detailed explanation of the mechanism of immunotherapy is not known, several immunologic explanation have been proposed. It's said that T cell-cytokine profile changed with allergen immunotherapy. In our study we evaluated IFN-* and IL-10 levels before and after immunotherapy in patients with allergic rhinitis. Twenty patients (mean age; 27.3 +/-(More)
BACKGROUND There is a tendency to use only one apheresis collection to reduce the morbidity and the cost of peripheral blood stem cell collection. We studied whether rapid and complete engraftment could be achieved by single apheresis by using only Filgrastim without large volume apheresis in previously treated patients. METHODS Engraftment of single(More)
Increased circulating soluble ICAM-1 (sICAM-1) levels has been previously reported in Graves' disease (GD) patients with or without ophthalmopathy (GO) and in patients with toxic nodular goiter but not in patients with subacute thyroiditis. Conflicting results have also been reported about the usefulness of sICAM-1 levels as a marker for the activity of(More)
