Unusual presentation of recurrent Wegener's granulomatosis.

A 65-year-old woman presented with recurrent Wegener's granulomatosis following two years of immunosuppressive therapy and three years of complete remission. At her initial presentation, she had a characteristic x-ray picture showing multiple nodules with total resolution of these findings at three months. Five years later, at the time of clinical relapse, her chest x-ray film showed bilateral diffuse infiltrative disease. This change in radiologic presentation upon relapse of Wegener's has not previously been reported. Other unusual features include diffuse infiltrates as the pulmonary presentation and the long interval between cessation of therapy and relapse. We review the radiologic manifestations of Wegener's granulomatosis.

Non-contraceptive hormones and the risk of rheumatoid arthritis in menopausal women.

BACKGROUND: Several reproductive factors appear to affect a women's risk of developing rheumatoid arthritis. This study's purpose was to determine whether use of non-contraceptive hormones is among them. METHODS: A population-based case-control study was conducted in King County, Washington and Group Health Cooperative of Puget Sound, a prepaid health plan. New cases of rheumatoid arthritis in peri- or postmenopausal women (n = 135) were verified through clinical examination and compared with 592 controls. Both groups were interviewed in person about hormone use and demographic and reproductive factors. RESULTS: The age-adjusted relative risk (RR) among women who had ever used non-contraceptive oestrogens was 1.04 (95% confidence interval [CI]: 0.70-1.55), and among women who had ever used progestins it was 0.66 (95% CI: 0.40-1.08). For current users of oestrogen only, the RR was 0.97 (95% CI: 0.62-1.53), and among current users of oestrogen plus progestin it was 0.81 (95% CI: 0.45-1.45). Multivariate analyses yielded similar results. There was little evidence of a dose-response relationship with duration of use or with frequency of progestin use. CONCLUSIONS: Use of non-contraceptive oestrogens appears to have little effect on the risk of developing rheumatoid arthritis in menopausal women. There may be a modest reduction in risk among progestin users.

Nontraumatic femur fracture in an oligomenorrheic athlete.

Exercise-associated amenorrhea is the cessation of menses in a woman following onset of training or an increase in training intensity. Its physiologic basis is characterized by consistently low levels of gonadotropin and ovarian hormones, but the underlying cause of this phenomenon is unknown. Although osteopenia has been described in amenorrheic women athletes, it has been primarily a laboratory diagnosis. Several recent studies have described a significantly lower bone mineral density (BMD) in the lumbar spine of amenorrheic athletes. Marcus et al. also reported an increased number of metatarsal and tibial stress fractures in a group of amenorrheic women. We report here the first case of a nontraumatic femur fracture in an amenorrheic athlete. A 32-yr-old white female, with four prior fibular stress fractures, suffered a left femoral shaft fracture during the 13th mile of a half-marathon. The fracture was successfully internally fixed. Biochemical studies showed no metabolic abnormality. Bone mineral density of the lumbar spine, femoral neck, tibia, and fibula were below the mean for both eumenorrheic and amenorrheic female athletes. Exercise-associated amenorrhea is a medical problem that may have serious implications for both competitive and high-intensity recreational female athletes.

Physicians as patients--the use of obstetric technology in physician families.

Birth records of King County, Washington, for 1980 through 1982 were reviewed to study the use of obstetric technology by physician and nonphysician families. The sample of 524 births to physician families was compared with 657 births to nonphysician families randomly selected from upper income census tracts. Though similar in demographic and medical characteristics and pregnancy outcomes, the two groups differed greatly in use of amniocentesis and cesarean section. Physician families used amniocentesis 1.65 times more often than nonphysician families and women physicians were 3 times more likely to have the procedure (relative risk [RR] 3.09). For female physicians 30 to 40 years old, the RR was 5.54. Similarly, physician rates for primary cesarean section were 1.56 times higher and rates for women physicians were twice as high as for controls (RR 2.14). This study suggests higher utilization rates among physicians for some procedures. These findings may foreshadow increases in utilization in the general population.

Evaluation of the 1987 revised criteria for rheumatoid arthritis in a cohort of newly diagnosed female patients.

The revised criteria for the diagnosis of rheumatoid arthritis (RA) were presented in 1987. We tested these criteria on 135 women from a population-based study of patients with newly diagnosed RA. None of the 19 women with probable RA and 100 of the 116 women with definite RA met the 1987 criteria. The 1987 criteria appear to be less sensitive or more specific than the criteria formulated in 1956.

Decreased testosterone levels in men with rheumatoid arthritis: effect of low dose prednisone therapy.

OBJECTIVE: To determine whether men with rheumatoid arthritis (RA) have abnormal hypothalamic-pituitary-gonadal axis function and to measure the effects of low dose prednisone therapy in these patients. METHODS: We measured testosterone, follicle stimulating hormone (FSH), and luteinizing hormone (LH) in 36 men aged 38-75 (mean age +/- 1 sd = 62 +/- 10 years) who had longstanding active RA (mean disease duration = 17 +/- 12 years) and in 70 healthy elderly male controls, aged 53-83 (mean age 68 = +/- 6 years). We divided the group with RA into those taking no prednisone (n = 12) and those taking 5 to 10 mg/day of prednisone (n = 24) and analyzed these groups separately to determine whether low doses of prednisone affected testosterone levels. RESULTS: Compared to the healthy controls, patients with RA not taking prednisone had normal testosterone levels but significantly elevated levels of FSH and LH (p < 0.01 for both comparisons). In contrast, patients with RA taking prednisone had significantly lower testosterone levels (p < 0.05), but levels of FSH and LH were only slightly elevated compared to controls. Compared to patients not taking prednisone, patients taking prednisone had lower levels of testosterone, FSH, and LH. CONCLUSION: Male patients with RA who are not taking prednisone have significantly elevated levels of FSH and LH with normal testosterone levels, suggesting a state of compensated partial gonadal failure. Male patients with RA taking low doses of prednisone have lower testosterone and gonadotropin levels, suggesting that prednisone may suppress the hypothalmic-pituitary-testicular axis. Since testosterone affects immune function as well as bone and muscle metabolism, androgen deficiency in some men with RA may predispose these patients to more severe disease and to increased complications of steroid therapy such as myopathy and osteoporosis.

Smoking, obesity, alcohol consumption, and the risk of rheumatoid arthritis.

There is some evidence that sex hormones may influence the incidence of rheumatoid arthritis. Obesity has been found to increase endogenous estrogens, particularly among postmenopausal women. Although the association of endogenous hormones with smoking and alcohol use is less clear, we examined the relation of these three factors with rheumatoid arthritis in women. We conducted a population-based case-control study of rheumatoid arthritis in King County, WA, and Group Health Cooperative of Puget Sound. We compared 349 incident cases of rheumatoid arthritis with 1,457 controls selected by random digit dialing or by random selection from the enrollment files of Group Health Cooperative. We conducted personal interviews to collect data on weight, smoking, alcohol history, reproductive variables, and other demographic variables. Women with 20 or more pack-years of smoking had a relative risk of 1.5 [95% confidence interval (CI) = 1.0-2.0] compared with never-smokers. Post-menopausal women who averaged more than 14 alcoholic drinks per week had a reduced risk of rheumatoid arthritis (relative risk = 0.5; 95% CI = 0.2-1.7). Women in the highest quartile of body mass index had a risk of 1.4 (95% CI = 1.0-2.0) relative to women with lowest body mass index.

Fecundity before disease onset in women with rheumatoid arthritis.

OBJECTIVE: To examine fecundity prior to disease onset in women with rheumatoid arthritis (RA). METHODS: Two hundred fifty-nine RA patients with an opportunity for pregnancy were compared with 1,258 control women as part of a prospective case-control study of recent-onset RA in women. RESULTS: A 12-month or longer interval to pregnancy was found in 42% of RA cases compared with 34% of controls (odds ratio = 1.44, 95% confidence interval 1.10, 1.91). This difference was not accounted for by an older age when attempting to become pregnant among the RA cases compared with the controls. The result was unrelated to rheumatoid factor or HLA-DR4 status. CONCLUSION: Women with RA were found to have decreased fecundity prior to disease onset, compared with control women.

Pregnancy outcome in women with rheumatoid arthritis before disease onset.

Pregnancy outcome before disease onset was evaluated for women with rheumatoid arthritis (RA) and control women as part of a prospective case-control study of newly diagnosed RA. An analysis of women who were ever gravid revealed no statistically significant difference in any adverse pregnancy outcome between RA cases (n = 144) and controls (n = 605) including spontaneous abortions and stillbirths. Thus, in contrast to reports both of an increase of adverse pregnancy outcomes and a decrease in women who subsequently develop RA, we found no evidence for any difference in pregnancy outcome in the RA group.

Diet and rheumatoid arthritis in women: a possible protective effect of fish consumption.

Some researchers have hypothesized that omega-3 fatty acids, found primarily in fish oils, may protect against the development of rheumatoid arthritis. We conducted a population-based case-control study in women, comparing 324 incident rheumatoid arthritis cases with 1,245 controls. We used a food frequency questionnaire to ascertain diet during a 1-year period 5 years before a reference date (first physician visit for joint-symptoms). Consumption of broiled or baked fish, but not of other types of fish, was associated with a decreased risk of rheumatoid arthritis. The adjusted odds ratios (OR) for 1- < 2 servings and > or = 2 servings of broiled or baked fish per week, compared with < 1 serving, were 0.78 [95% confidence interval (CI) = 0.53-1.14] and 0.57 (95% CI = 0.35-0.93). Other analyses showed associations with protein as a percentage of calories (adjusted OR for the top quartile as compared with the bottom quartile = 0.65; 95% CI = 0.46-0.94) and total calories (adjusted OR for the top quartile = 1.62; 95% CI = 1.15-2.28). The associations with broiled or baked fish, protein, and calories became stronger when we restricted our analysis to cases positive for rheumatoid factor. These results support the hypothesis that omega-3 fatty acids may help prevent rheumatoid arthritis.

Rheumatoid arthritis in women. Incidence rates in group health cooperative, Seattle, Washington, 1987-1989.

As part of a prospective case-control study of newly diagnosed rheumatoid arthritis (RA) in women, we identified all cases of probable, definite, or classic RA diagnosed in 1987-1989 in 18-64-year-old women who were members of a health maintenance organization based in the Seattle, Washington area. Using both the 1958 and the 1987 American Rheumatism Association criteria for the diagnosis of RA and enrollment data from the health maintenance organization, we calculated the incidence by age and diagnostic class. Rates of RA incidence in women increased steadily with age. The incidence of probable, definite, or classic RA ranged from 13.1 per 100,000 person-years at risk for 18-29-year-old women to 82.1 per 100,000 person-years for 60-64-year-old women. The overall incidence rate, age-adjusted to the 1980 US female population, was 27.9/100,000 person-years. The overall incidence rate for definite/classic RA, age-adjusted to the 1980 US female population, was 23.9 per 100,000 person-years. When compared with adjusted rates of incidence of definite RA in Rochester, Minnesota, in 1950-1974, the incidence rates we found were 44.7% lower. Methodologic differences, changes in diagnostic criteria, and a declining incidence of RA among women over time may all be partial explanations for these results. The possible effects of reproductive factors, including oral contraceptives use, are discussed.

Rheumatoid factor, HLA-DR4, and allelic variants of DRB1 in women with recent-onset rheumatoid arthritis.

OBJECTIVE: To examine the relationship of rheumatoid factor (RF) to HLA-DR4 and alleles of DRB1 in women with recent-onset rheumatoid arthritis (RA). METHODS: Incident cases of RA were identified as part of a prospective, population-based case-control study. HLA typing was completed for 246 cases meeting criteria for definite or classic RA. RESULTS: One hundred thirty-six patients (55%) were positive for DR4, and 130 (53%) were RF positive. DR4 was found to be strongly associated with seropositivity (odds ratio 4.1, P < 0.0001). Patients with a shorter interval from RA onset to RF testing had a higher frequency of seropositivity than those with a longer interval (< or = 18 months 60%, > 18 months 33%). Further analysis of patients who had RF testing within 18 months of RA onset showed that the frequency of seropositivity was significantly greater among DR4-positive patients who had the shared sequence stretch of DR beta 1 associated with RA susceptibility (76% RF positive) than among DR1-positive patients who had this sequence (45% RF positive) (odds ratio 3.8, P = 0.01). Moreover, the frequency of seropositivity among DR1-positive patients with the sequence did not differ from that among all patients without the shared sequence (47%) (odds ratio 0.9, P = 0.8). CONCLUSION: HLA-DR4 is strongly associated with seropositivity in women with recent-onset RA. The amino acid sequence of DR beta 1 that is associated with susceptibility to RA and is shared between DR4 and DR1 appears not to be the primary determinant of seropositivity in these women.
