- Leuprolide is a gonadotropin-releasing hormone (GnRH) analog which has been shown to reduce symptoms in patients with irritable bowel syndrome (IBS) and chronic intestinal pseudo-obstruction (CIPO). The mechanism is not known, but one hypothesis is through down-modulation of luteinizing hormone (LH) secretion, a hormone whith antagonistic effect on gastrointestinal motility. However, presence of LH receptors in the gastrointestinal tract has never been described. The aim of this study was to find one possible way of action for leuprolide by examining the presence of the LH receptor, and if present, to see whether there was different expression in patients with or without dysmotility. Full-thickness biopsies from the bowel wall of patients with and without severe dysmotility were examined using immunohistochemistry staining. Biopsies showed expression of LH receptors on myenteric neurons and in glial cells, neutrophils, endothelial cells and mast cells. There was no difference in expression between patient groups.

- Evidence of interactions between the enteric nervous system, neuropeptides, and the immune system is growing. The aim of this study was to examine basal plasma levels of a variety of peptide precursors in patients with inflammatory bowel disease (IBD). In two middle-aged cohorts, Malmö Preventive Medicine (n = 5,415) and Malmö Diet and Cost Study (n = 6,103), individuals with the diagnosis of IBD were identified. Medical records were scrutinized. Three controls were matched for each patient. Copeptin, midregional fragments of adrenomedullin, pro-atrial natriuretic peptide, and proenkephalin A, as well as N-terminal protachykinin A and proneurotensin were analyzed in the plasma. Sixty-two IBD patients were identified. The only difference between patients and controls was higher copeptin levels in the patients compared with controls (P = 0.006), with higher copeptin levels in resected than unresected patients (P = 0.020). There was no difference in any precursor levels between Crohn's disease and ulcerative colitis, between different distributions of disease lesions, or between different treatments.

- Patients with functional gastrointestinal disorders express antibodies against gonadotropin-releasing hormone (GnRH) in serum. One common cause of posterior laryngitis (PL) is extra-esophageal reflux, but a functional etiology has also been suggested. The aim of this study was to scrutinize patients with PL with regard to the presence of GnRH antibodies and to examine the association between antibodies and symptoms and reflux. Consecutive PL patients were included after examination. Serum was analyzed for the presence of antibodies using an enzyme-linked immunosorbent assay (ELISA) method and expressed as relative units (RU). Two age- and gender-matched healthy subjects per case served as controls. The prevalence of IgM GnRH antibodies in patients was 35% compared with 28% in controls (P = 0.06), with higher levels in patients (0.8 (0.3-2.2) RU) than in controls (0.2 (0.1-0.6) RU) (P = 0.007). The corresponding IgG antibody prevalences were 43% and 4%, respectively (P = 0.001), with no difference in levels (P = 0.70). There was no association between antibodies and clinical findings

- Microscopic colitis (MC) often debuts around or after menopause and is divided into lymphocytic- and collagenous colitis. The aim of this study was to examine whether factors influencing sex hormone levels differed between subgroups of MC as well as between patients and controls. A self-administered questionnaire about parity was completed which included questions surrounding age at first childbirth, menarche and menopause, the use of oral contraceptives, and hormonal replacement therapy. Patients with lymphocytic colitis had children less often compared to those with collagenous colitis (OR = 0.20, 95% CI = 0.05-0.86), however no differences were observed between patients with persistent or transient disease. Patients were less often older than 15 years of age at menarche (OR = 0.48, 95% CI = 0.26-0.91) and were younger at menopause (OR = 0.30, 95% CI = 0.16-0.56) compared with controls. Thus, no obvious association between factors influencing sex hormone levels and presence of MC could be found.

- Microscopic colitis (MC) is a disease with intestinal mucosal inflammation causing diarrhea, affecting predominantly middle-aged women. The etiology is unknown, but increased prevalence of autoimmune diseases in these patients has been described, although not compared with controls or adjusted for confounding factors. The aim of this study was to examine the prevalence of common diseases in patients with MC and controls from the general population. Hypertension, rheumatoid arthritis, asthma or bronchitis, ischemia, and diabetes mellitus were more prevalent in patients than in controls. The prevalence of gastric ulcer and cancer did not differ between the groups. Besides corticosteroids, many patients were also being treated with proton pump inhibitors, antidepressant drugs, angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists, statins, thyroid hormones, and beta-blockers. More patients than controls were former or current smokers (72.5% versus 57.7%). Thus, MC patients have an increased prevalence of several diseases, not only of autoimmune origin.

Tidskriftsartikel (refereegranskat)abstract
- Gonadotropin-releasing hormone (GnRH) 1 and 2 and luteinizing hormone (LH) receptors have been described in the gastrointestinal tract. We have previously demonstrated antibodies in serum against GnRH1 in patients with gastrointestinal dysfunction and diabetes mellitus, and antibodies against GnRH receptor, LH, and LH receptor in patients with infertility. The aim of this study was to search for the expression of serum antibodies against GnRH1 with an improved enzyme-linked immune sorbent assay (ELISA), and antibodies against progonadoliberin-2, GnRH2, GnRH receptor, LH, and LH receptor with newly developed ELISAs, in patients with gastrointestinal dysfunction or diabetes mellitus. Healthy blood donors served as controls. Medical records were scrutinized. Our conclusion was that IgM antibodies against GnRH1, progonadoliberin-2, and/or GnRH receptors were more prevalent in patients with functional gastrointestinal disorders, gastrointestinal dysmotility, and/or diabetes mellitus, whereas IgG antibodies against these peptides, and LH- and LH receptor antibodies, were expressed in the same magnitude as in controls.
