Endometriosis (EM) is an oestrogen-dependent disease affecting 10-15 % of women during reproductive age. It is characterised by the presence of endometrial glands, stromal- and smooth muscle-like cells outside of the uterine cavity. Fifty t…

BACKGROUND: Recent studies demonstrated the potential involvement of nerve fibres in the chronic inflammatory process of endometriosis. We aimed to characterize nerve fibres in the proximal and distal areas of the peritoneal endometriotic l…

To investigate the neurotrophic properties of endometriosis, as well as the involvement of neurotrophic factors in the development of chronic pelvic pain in patients with endometriosis, we performed a prospective clinical study. The presenc…

OBJECTIVE: To investigate neuronal remodeling processes in the uterine innervation, particularly a remodeling of sympathetic nerve fibers, as well as the role of estrogen in this modulation in adenomyosis. DESIGN: Retrospective case-contro…

The role of neurotrophins in eutopic endometrium from endometriosis-patients was investigated in a prospective study using immunofluorescence-staining, Western blot and a neuronal growth assay. The nerve growth factor is expressed in primar…

To investigate the occurrence of lymph vessels and lymphangiogenic growth factors in peritoneal lesions, we performed immunohistochemical staining of peritoneal lesions of 37 patients with antibodies against podoplanin (D2-40), lymphatic ve…

OBJECTIVES: An imbalance in the ratio of sensory to sympathetic nerve fibre (NF) density in peritoneal endometriotic lesions (pEL) has recently been demonstrated and leads to the assumption that this preponderance of the sensory pro-inflamm…

To investigate the involvement of neurotrophins and nerve fibres in the pathogenesis of adenomyosis, we performed a retrospective, clinical study. Hysterectomy specimens from 40 patients with histologically proven adenomyosis and from 20 pa…

To investigate possible mechanisms of pain pathophysiology in patients with peritoneal endometriosis, a clinical study on sensory and sympathetic nerve fibre sprouting in endometriosis was performed. Peritoneal lesions (n=40) and healthy pe…

BACKGROUND: Smooth muscle cells (SMC) are common components of endometriotic lesions. SMC have been characterized previously in peritoneal, ovarian and deep infiltrating endometriotic lesions and adenomyosis. The aim of this retrospective s…

To investigate the role of the nerve growth factor (NGF) in the development of dysmenorrhea/pelvic pain in patients with endometriosis, we performed a prospective, clinical, blind study. Peritoneal fluids (PFs) were obtained from patients w…

BACKGROUND: In patients diagnosed with deep infiltrating endometriosis (DIE), foci of endometriosis are detected in mesorectal lymph nodes (LNs) after segmental bowel resection and in pelvic sentinel LNs. Lymph vessels (LVs) seem to be the …

To investigate the role of the nerve growth factor (NGF) in the endometriosis-associated innervation in the development of endometriosis-associated symptoms, 41 peritoneal fluid samples (PF) from patients with surgically and histologically …
