menotropins and Drug-Hypersensitivity

This report describes a patient who experienced a generalized allergic reaction to Pergonal during controlled ovarian hyperstimulation in preparation for an intracytoplasmic sperm injection procedure for treatment of severe male factor infertility. The report describes a successful desensitization protocol which allowed the patient to complete her treatment cycle despite the allergic reaction to Pergonal. Subsequently recombinant follicle stimulating hormone was used successfully in inducing follicular growth in the absence of any allergic reactions. Therefore, this report confirms other studies which have suggested that an allergic reaction to human menopausal gonadotropins is due to impurities in such urine-derived products.

We report a case of general hypersensitivity-like allergic reactions to intramuscular injections of highly purified urinary follicle stimulating hormone (uFSH-HP) successfully managed by using intramuscular recombinant FSH (rFSH). The patient underwent a first cycle of in vitro fertilization (IVF) and controlled ovarian hyperstimulation (COH) was achieved with a combination of gonadotropin releasing hormone against (GnRH-a) and uFSH-HP. Because, after oocyte recovery, no fertilization occurred, the couple subsequently entered an intracytoplasmic sperm injection (ICSI) program. During the COH, the woman developed general hypersensitivity-like allergic reactions with itching, redness and swelling. Although there was regular follicular growth, the allergic symptoms worsened and, on day 8 of COH, the stimulation cycle was suspended. A few months later, the patient entered a new ICSI cycle. COH was achieved by using a combination of GnRH-a and rFSH. The cycle was completed and the patient did not report any allergic reaction. To avoid allergic reaction to the protein components of the urine-derived FSH preparations, the use of rFSH is suggested in those patients who present local and/or general hypersensitivity-like allergic reactions.

We report a case of allergic reaction to i.m. injections of urinary human menopausal gonadotrophin (HMG) and a successful management of the problem by using recombinant follicle stimulating hormone (rFSH) administered i.m. The patient underwent two zygote intra-Fallopian transfer (ZIFT) cycles, in which ovarian stimulation was carried out by a combination of gonadotrophin-releasing hormone agonist (GnRHa) and HMG. A twin pregnancy was achieved after the first cycle. The patient delivered two premature boys at 28 weeks one of whom died after 25 days from severe respiratory distress. During the second ZIFT cycle the patient developed an allergic reaction with redness and swelling in many parts of her body 30 min after every HMG injection. Despite the allergic reaction, the cycle was completed with a second ZIFT. No pregnancy was achieved in this cycle. The patient came back to our centre for a third attempt during which ovarian stimulation was accomplished with a combination of GnRHa and rFSH. Adverse reaction as well as general discomfort were not reported by the patient during ovarian stimulation with rFSH. A successful singleton pregnancy was achieved after intrauterine embryo transfer with the birth of a healthy girl after 38 weeks. If any allergic reaction is present after injection of HMG it is advisable to stimulate a subsequent cycle with rFSH.

Local reactions have been frequently reported following repeated injections of human menopausal gonadotrophins (HMG) for the treatment of infertility. Also immunoglobulin (Ig) E-mediated systemic reactions have sporadically been observed. Since most HMG preparations contain significant amounts of non-hormonal urine-derived proteins, it was suggested that these contaminating proteins are responsible for the various allergic reactions. In order to verify this hypothesis, different human follicle stimulating hormone (HFSH) and HMG preparations (Metrodin and Pergonal from Ares-Serono, and Humegon from Organon), were compared with a highly purified preparation (Metrodin HP from Ares-Serono) for the frequency and severity of allergic reactions induced in laboratory animals. The occurrence of anaphylactic shock or related symptoms was studied in sensitized guinea-pigs. The production of specific IgE was evaluated in serum from mice sensitized with the test drugs by the induction of passive cutaneous anaphylaxis in rats. In both models, two different schedules of sensitization were used. Severe allergic reactions were found in 20 of 7% of the guinea-pigs receiving highly purified FSH (Metrodin HP) in the two schedules, respectively, compared to 90 and 88% with the other preparations. Similarly significantly lower IgE titres were induced by highly purified FSH in respect to the other preparations. It can be concluded that the elimination of contaminating proteins significantly reduces the allergenicity of urine-derived HFSH preparations.
