Urinary dedifferentiated podocytes were shown in active LN, and their protein levels correlated with proteinuria and histological features in LN. These preliminary results suggest that it could be a potentially useful non-invasive marker for evaluating the progression of glomerular disease in SLE.

Hypertensive patients who had elevated UAE showed increased urinary excretion of podocyte-specific proteins coupled with a phenotype of decreased mRNA expression. The phenotype of podocyte-specific mRNA and the increment of nephrin can be used as a valuable marker of early glomerular injury.

Multiple ovulation was induced in 122 hypogonadotrophic IVF patients with large doses of HMG. The hypogonadotrophic state, short and reversible, was obtained by nasal administration of a GnRH agonist (200 micrograms, five times per day). In the 97 induced cycles, a mean of 9.1 follicles was recorded. A comparison of the results obtained for 36 patients who had already been treated with clomiphene and HMG showed both significantly more follicles per cycle (8.5 versus 3.0) and an increase in oocytes retrieved (6.7 versus 1.3) when treated with the agonist and HMG. In addition 11 of 18 already poorly responsive patients had normal responses. The luteal phase was supported by either HCG or progesterone injection. Plasma progesterone profiles were satisfactory and, as expected, the highest progesterone concentrations were associated with HCG treatment.

Direct intraperitoneal insemination (DIPI) is one of the least invasive strategies of assisted reproduction. Unexplained infertility and male sub-fertility are the major indications for DIPI. It is otherwise well known that assisted procreation gives poor results in severe male infertility. This is a report of a pregnancy that occurred as a result of a direct intraperitoneal insemination of prepared spermatozoa characterized by a particularly severe astheno-teratozoospermia in a couple unsuccessfully treated with other, more invasive methods of assisted fertilization.

Summary. Twenty infertile patients with normal tubal patency were inseminated intraperitoneally (11 once, seven twice, and two three times) with spermatozoa (mean 14 times 106, range 0.6–48 times 106) prepared by the standard swim‐up technique. The occurrence of immunization to spermatozoa was looked for by the Gelatin Agglutination Test (GAT) and Tray Agglutination Test (TAT). Both tests gave negative results for all the controls (10 pregnant and 10 puerperal women). Antisperm antibodies were measured in the serum before, 30 d and 4–7 months after Intraperitoneal Insemination (IPI). The last check was done for only 14 patients, since six became pregnant as a consequence of the first treatment. Of the 14 patients studied after 4–7 months, seven had two, and two had three IPI. In the group of inseminated patients, 18 women with no basal sperm antibody did not show evidence of antibody formation after the treatment and it was not increased after insemination in the two patients who already had low antibody titre (1/32). In conclusion, despite the large number of spermatozoa inseminated and even after several IPI attempts, there was no evidence of de novo production of or increase in already present anti‐sperm antibodies according to the methods used for the detection of ASA in this study.
