Definitions

  • the present invention relates to the use of compositions comprising an anti-LHRH vaccine for the control or treatment of urinary incontinence.
  • the present invention further relates to methods of treating or controlling urinary incontinence in mammals, and in particular, in those that have been surgically neutered, e.g., spayed female dogs.
  • Urinary incontinence is the involuntary loss or passing of urine consequent to bladder or urethral sphincter dysfunction.
  • the urethral sphincter closes tightly to prevent leaking.
  • the urethral sphincter relaxes and allows urine to pass through the urethra.
  • Urinary incontinence is often the result of loss of urethral sphincter tone, which lessens its ability to tighten.
  • urinary incontinence occurs in an uncontrolled manner whenever the pressure within the bladder exceeds the pressure required to close the urethra. This problem is often more noticeable when the mammal is relaxed, such as during deep sleep, or when pressure on the bladder is momentarily increased, such as when the mammal coughs or sneezes.
  • urinary incontinence is prevalent among adult women. Because of the social stigma associated with urinary incontinence, many sufferers do not even report the problem to a health care provider. As a result, this medical problem is vastly under-diagnosed and under-reported.
  • Urinary incontinence is also quite common in dogs. Usually, it occurs in female dogs, and most often in the spayed female dog. Male dogs are prone to this condition as well, but less commonly so than their female counterpart. Previously, it has been explained that the underlying mechanism of incontinence in spayed or neutered dogs is related to low post-surgical estrogen or testosterone concentrations following the removal of the ovaries or testes.
  • estrogen hormone is believed to be responsible for providing tone to the urethral sphincter muscle. Following spaying, estrogen hormone is produced in significantly lower amounts than it was prior to the removal of the ovaries. While the adrenal glands produce small amounts of estrogen hormone, it was believed that the levels produced are insufficient to provide sphincter tone. In such cases, incontinence can occur and some form of treatment is then required to support sphincter tone.
  • male dogs can develop urinary incontinence following neutering, as the testes, the primary testosterone source, are removed.
  • Treatment for urinary incontinence has traditionally been aimed at improving the urethral closure pressure.
  • these medicaments include alpha-adrenergic substances, such as ephedrine or phenylpropanolamine ("PPA").
  • PPA phenylpropanolamine
  • Treatment with the above typically involves a long-term use of the medicaments and has been shown to cause severe cardiac electrophysiological side effects in humans. These adverse side effects can include, but are not limited to, ventricular fibrillation and cardiac arrhythmias. Such potentially lethal cardiac side effects have led to the withdrawal of several medications for humans from the market, including PPA, which has recently been recalled by the U.S. Food and Drug Administration (“FDA").
  • Alpha-adr ⁇ n ⁇ rgic substances are also contrai ⁇ dlcated in case of glaucoma and progressive nephropathy.
  • estrogen or oestradiol e.g., diethylstilbestrol
  • testosterone in the case of male dogs replacement therapy
  • estrogen therapy is widely considered less safe than the use of alpha-adrenergic substances since it can lead to bone marrow suppression in dogs, which can be fatal.
  • LHRH Luteinizing Hormone Releasing Hormone
  • GnRH Gonadotropin Releasing Hormone
  • GnRF Gonadotrophs Releaseing Factor
  • the receptor cells in the anterior pituitary gland respond to the rise in LHRH by releasing the gonadotropins, FSH and LH.
  • the relative levels of FSH and LH that vary over the course of the oestrus cycle in turn stimulates the production of estrogen by the ovaries.
  • estrogen is measurable only in very low serum concentrations.
  • Other hormones that usually originate in the gonads such as the inhibins that are secreted in the ovary by granulose cells selectively inhibit pituitary FSH sectretion.
  • LHRH antagonists or agonists are required to achieve the desired anttgonadotropic effects.
  • the effects of using such analogues are immediate, they are of short duration and therefore, require frequent administration.
  • large amounts of these analogues may cause undesirable or adverse side effects. They are also very expensive since their use, and hence their availability, is usually limited to the treatment of hormone dependant tumors.
  • LHRH antibodies in addition to being quite costly, have the disadvantage of having rather short half-lives, which result in short durations of treatment and the potential requirement for multiple doses.
  • the necessary frequent and continuous administration of LHRH antibodies using this approach would be both costly and inconvenient to dog owners. Accordingly, LHRH analogs are not of practical use for veterinary applications as such.
  • an alternative and/or additional approach to urinary incontinence therapy heretofore unrecognized- is to target the immune system through the use of vaccine compositions.
  • a potential benefit of active immunotherapy is to provide improved efficacy by enhancing the subject's own immune response to the effective and long-lasting control of unrestricted production and release of gonadotropins, FSH and LH.
  • the present invention relates to anti-LHRH vaccines and the use thereof for the treatment or control of urinary incontinence in mammals.
  • the present invention provides a method for the treatment of urinary incontinence In a mammal in need of such treatment, wherein the method comprises administering to the mammal a therapeutically effective amount of an anti-LHRH vaccine.
