Opis:
Prostate Specific Antigen (PSA), a member of kallikrein family, is a specific serine protease of prostatic tissue. In some case reports, changes in PSA levels after acute myocardial infarction (AMI) have been reported. In this study we evaluated variations in PSA levels post-AMI. Twenty-six male patients who had PSA levels within reference limits were included in the study. The diagnosis of AMI was confirmed by clinical findings, ECG (electrocardiogram) and cardiac marker studies. Serum total PSA (tPSA) and free PSA (fPSA) levels were measured at days 0 (day of admission), 1, 2 and 3 after AMI. PSA/albumin ratio was also calculated in order to evaluate the effect of dilution. A statistical analysis of the results of all patients revealed significant decrease in tPSA levels and tPSA/Albumin ratio at day 2 when compared to days 0 and 3, which showed a similar pattern. Changes of fPSA and fPSA/ Albumin ratio according to days were not found significant. In only four patients we found increased levels of tPSA and increased fPSA levels in three of them. These patients displayed severe problems such as renal failure, cardiac failure, ventricular aneurysm and cerebral ischemia due to cardiac arrest. The lower tPSA levels on day 2 suggest that tPSA can be eliminated rapidly from the circulation on days 1 and 2, probably through the formation of complexes of tPSA with acute phase proteins.

Opis:
Preeclampsia is a multisystem disorder that can manifest clinically with hypertension and proteinuria. Previous studies reported the presence of placental PSA in normal pregnancy but no study has been done in preeclampsia. The aim of this study was to investigate PSA content in preeclampsia. Preeclampsia was diagnosed according to the American College of Obstetricians and Gynecologists criteria. Placentas were obtained from 33 preeclamptic and 34 normotensive women. Placenta samples were homogenized and the supernatants were immediately analyzed. The tissue PSA content was measured by Immulite 2000 PSA assay. The data were analyzed with Student's t-test and Pearson correlation test. There was a significant difference in placental PSA content between preeclamptic and normotensive women. Placental content of PSA was higher in the preeclamptic group with intrauterine growth restriction (IUGR) than in the preeclamptic and normotensive pregnant without IUGR groups. No significant difference was found in this respect between preeclamptic and normotensive women without IUGR. In conclusion, we found that placental PSA content is elevated in preeclampsia and negatively correlated with infant birth weight. Further studies will be necessary to define the roles of PSA more precisely and to examine its effects on the pathophysiology of preeclampsia.

Opis:
Prostatic acid phosphatase (PAP) and prostate-specific antigen (PSA) are the markers of human prostatic gland. However, it is still not completely understood if and how, steroid hormones and growth factors affect their expression and metabolism in the respect to the major pathologies of the gland. Appropriate studies were carried out on histopathologically diagnosed benign prostatic hyperplasia - BPH (n = 42) using tissue slices and cells derived from them. They were incubated with steroid hormones: 5-α-dihydrotestosterone (DHT), estradiol (E) and growth factors: epidermal growth factor (EGF), basic fibroblastic growth factor (bFGF) under culture conditions for up to 24 hours. 32P-labelled specific oligonucleotide probes were used to analyze total RNA isolated from each sample for the presence of PAP and PSA mRNAs. DHT, E, bFGF, EGF or both DHT + bFGF and DHT + EGF increased PAP and PSA mRNA levels in a time- and dose-dependent manner. The highest and statistically significant increase (P <0.001) for PAP mRNA was observed when DHT + bFGF were present in the medium while for PSA mRNA if DHT + EGF were added to the medium. Slow but constant decrease of PAP and PSA mRNA levels was observed in the absence of each of these factors in the incubation medium. The results suggest that early expression of PSA and PAP genes and/or their mRNA stability strongly depend on DHT while differ in their response to EGF and bFGF.
