Objective To determine whether nerve fibers can be detected in the endometrium and myometrium in women with painful uterine fibroids and adenomyosis. Design A retrospective immunohistochemical study. Setting An academic training hospital. Patient(s) Thirty-seven women with uterine fibroids and 29 women with adenomyosis. Intervention(s) Histologic sections of contiguous endometrial and myometrial tissues were stained immunohistochemically using the highly specific polyclonal rabbit antiprotein gene product 9.5 (PGP9.5) and monoclonal mouse antineurofilament protein (NF). Main Outcome Measure(s) Results were determined through immunohistochemical staining using PGP9.5 and NF. Result(s) We detected PGP9.5-immunoactive nerve fibers in the functional layer of the endometrium in women with pain but not in women without pain. PGP9.5-immunoactive nerve fiber density in the basal layer of the endometrium or myometrium significantly increased in women with pain, however, PGP9.5-immunoactive nerve fiber density had no statistical differences between women with adenomyosis and uterine fibroids. We identified NF-immunoactive nerve fibers in the basal layer of the endometrium and myometrium in women with adenomyosis and uterine fibroids, but found no significant differences. Conclusion(s) These results suggest that PGP9.5-immunoactive nerve fibers appearing in the endometrium and myometrium of women with painful adenomyosis and uterine fibroids may play a role in pain generation in these two disorders.

BACKGROUND: Deep infiltrating endometriosis (DIE) is a specific type of endometriosis, which can be associated with more severe pelvic pain than other forms of endometriotic lesions. However, the mechanisms by which pain is generated are not well understood. METHODS: DIE (n = 3I) and peritoneal endometriotic (n = 40) lesions were sectioned and stained immunohistochemically with antibodies against protein gene product 9.5, neurofilament, nerve growth factor (NGF), NGF receptors tyrosine kinase re...

Background: Dysmenorrhea is the most common gynecologic complaint among adolescent and young adult females. Dysmenorrhea is usually primary and is associated with normal ovulatory cycles and with no pelvic pathology. In ∼ 10% of females with severe dysmenorrhea symptoms, pelvic abnormalities such as endometriosis or uterine anomalies may be found. Objective: To review the current knowledge regarding the pathophysiology of dysmenorrhea, as well as review pharmacological treatments and strategies ...

BACKGROUND: Danazol, a synthetic steroid with antigonadotrophic properties, has been widely used for the treatment of endometriosis and adenomyosis. However, the local application of danazol to the uterus to treat adenomyosis is controversial. The objective of this study is to develop an effective treatment for adenomyosis using danazol via intrauterine contraceptive device (IUCD) delivery. METHODS: An adenomyosis animal model was established using Institute for Cancer Research, Swiss-derived (I...

This minireview reports current hypotheses concerning the remodeling of sympathetic innervation in rodent and human uterus during the estrous cycle and gestation. Neural modulation in this organ is related to sexual hormone concentrations, and a reduction in nerve density is observed when estrogen levels are high during the estrous cycle. Estrogen receptor alpha is considered to be the major receptor mediating the action of estrogen. In the uterus, the expression of neurotrophins, such as nerve ...

Uterine fibroids, the most common tumours in women of reproductive age, are asymptomatic in at least 50% of afflicted women. However, in other women, they cause significant morbidity and affect quality of life. Clinically, they present with a variety of symptoms: menstrual disturbances including menorrhagia, dysmenorrhoea and intermenstrual bleeding; pelvic pain unrelated to menstruation; and pressure symptoms such as a sensation of bloatedness, increased urinary frequency and bowel disturbance....

The ideal medical therapy for fibroids is, arguably, a tablet that is taken by mouth, once a day or, even better, once a week, with minimal, if any, side-effects, that induces fibroid regression and thus a resolution of symptoms rapidly, but without affecting fertility. Such a magic bullet does not yet exist, and there are no indications that one is on the horizon. Driven by the observation that fibroid growth is hormone dependent, current medical treatments mainly involve hormonal manipulations...

Dysmenorrhoea and intermenstrual pelvic pain are the most common symptoms of clinical manifestations of adenomyosis, which significantly impair the quality of women’s life. Adequate and long-term pain correction and alternative therapeutic approaches became extremely important for patients with adenomyosis during the COVID-19 pandemic. Research objective: to examine the clinical efficacy of nitric oxide donor (L-arginine) in the complex treatment of pelvic pain syndrome associated with adenomyos...

Background Accumulating data indicate that sensory nerve derived neuropeptides such as substance P and calcitonin gene related-protein (CGRP) can accelerate the progression of endometriosis via their respective receptors, so can agonists to their respective receptors receptor 1 (NK1R), receptor activity modifying protein 1 (RAMP-1) and calcitonin receptor-like receptor (CRLR). Adrenergic β2 receptor (ADRB2) agonists also can facilitate lesional progression. In contrast, women with endometriosis ...

Adenomyosis remains an enigmatic disease in the clinical and research communities. The high prevalence, diversity of morphological and symptomatic presentations, array of potential etiological explanations, and variable response to existing interventions suggest that different subgroups of patients with distinguishable mechanistic drivers of disease may exist. These factors, combined with the weak links to genetic predisposition, make the entire spectrum of the human condition challenging to mod...

Current therapies for the treatment of chronic pain provide inadequate relief for millions of suffering patients, demonstrating the need for better therapies that will treat pain effectively and improve the quality of patient's lives. Better understanding of the mechanisms that mediate chronic pain is critical for developing drugs with improved clinical outcomes. Adenosine triphosphate (ATP) is a key modulator in nociceptive pathways. Release of ATP from injured tissue or sympathetic efferents h...

Adenomyosis is a common disorder of the uterus, and is associated with an enlarged uterus, heavy menstrual bleeding (HMB), pelvic pain, and infertility. It is characterized by endometrial epithelial cells and stromal fibroblasts abnormally found in the myometrium where they elicit hyperplasia and hypertrophy of surrounding smooth muscle cells. While both the mechanistic processes and the pathogenesis of adenomyosis are uncertain, several theories have been put forward addressing how this disease...

STUDY QUESTION: Are selective markers for the neuronal differentiation such as microtubule-associated protein 2 (MAP-2) and synaptophysin (SYP) as well as the nerve growth factor (NGF) expressed by fibroids, myometrium and eutopic endometrium? SUMMARY ANSWER: Neuronal markers NGF, MAP-2 and SYP are highly expressed in fibroids compared with matched myometrium, and this neurogenic pathway is upregulated by tumor necrosis factor (TNF) alpha in cultured smooth muscle cells (SMCs).
