Collagen metabolism markers as a reflection of bone and soft tissue turnover during the menstrual cycle and oral contraceptive use.

Two different groups of women, 23 healthy young adults and 13 women with chronic posterior pelvic pain, were studied before and during use of oral contraceptives (OC). Collagen metabolism markers-here, the amino-terminal propeptide of type I procollagen, the carboxy-terminal telopeptide of type I collagen, and the amino-terminal of procollagen type III-as well as hormones and other endocrine factors indicating the balance between androgen expression/anabolism and catabolism of the subjects (testosterone, sex-hormone binding globulin, and insulin-like growth factor I were measured. Type I procollagen, the carboxy-terminal telopeptide of type I collagen, and the amino-terminal of procollagen type III were all significantly decreased during OC use. These findings implicate OC use-induced changes in collagen type I and III turnover. A shift in the anabolic/catabolic balance was also recorded indicating a less anabolic situation during OC use.

Oral contraceptives and back pain in women in a Swedish community.

BACKGROUND: Female back pain is a clinical problem-especially low back pain with symptoms from the pelvic posterior region-that is often aggravated in connection with pregnancy and childbirth. Hormones have been suggested as an aetiologic factor. This study is aimed to determine whether additional hormone preparations, i.e. oral contraceptives (OC), may contribute to the increased frequency of such pain. METHODS: A register study was conducted to investigate the use of drugs and health care use in a female population with known OC consumption. Specifically, we registered the number of primary health care visits for low back pain, comparing OC users with non-OC using age-matched women with otherwise equal circumstances. RESULTS: OC users recorded a significantly higher incidence of low back symptoms during the study period compared to non-users. Pregnancy was not found to be a confounding factor. CONCLUSIONS: The intriguing association between OC use and a higher incidence of low back pain, does not enable us to conclude that there is a causal connection, but it should lead to further studies.

Serum levels of relaxin during the menstrual cycle and oral contraceptive use.

Serum relaxin levels were analysed in 12 healthy women every other day during the menstrual cycle and during a second cycle on oral contraceptives. Relaxin levels in 7 women with posterior pelvic and lumbar pain were also measured. Relaxin was detected during both the follicular and luteal phases of the menstrual cycle in some of the healthy women. Serum levels were further increased during the use of oral contraceptives. Oestradiol levels in the untreated women correlated to the relaxin levels. Women with posterior pelvic and lumbar pain had higher relaxin levels than did healthy women, a finding that needs to be further explored. Our data indicate the existence of sources for relaxin production other than the corpus luteum in the non-pregnant woman. Endogenous and exogenous oestrogens may stimulate the production of relaxin.

Treatment of pelvic joint dysfunction in primary care--a controlled study.

The study evaluated the manual treatment of dysfunction of the pelvic joints. This is one of many condition causing low back pain. In 1987-1988 a general practitioner with special knowledge of physical examination and manual treatment of lumbar and pelvic dysfunctions made a survey of patients with acute or subacute low back pain as the main cause of the patient-to-doctor contact. Patients with defined criteria of pelvic joint dysfunction (n = 46) were randomized. After dropouts and exclusions, 18 patients with defined criteria of pelvic joint dysfunction received manual treatment, while 21 patients with similar dysfunction served as controls and received placebo treatment in a form of massage. Both groups were seen only once to evaluate whether a single treatment might be sufficient. After a period of three weeks, evaluation was made by an independent observer. Subjective pain measurement and a mobility test showed no significant difference. Sick-leave and consumption of analgesics (both decided by patient) were significantly less in the treatment group.
