Combination therapy of cyclosporine with methotrexate and gold in rheumatoid arthritis (2 pilot studies).

OBJECTIVE: To evaluate the efficacy and toxicity of cyclosporine A (CyA) in combination with gold and methotrexate (MTX) in patients with rheumatoid arthritis (RA). METHODS: Twenty patients with RA with partial response to oral MTX and 20 patients with partial response to im gold had CyA added to their regimen for 6 months, withdrawn over 2 months and the patients monitored for 4 months. RESULTS: There was a significant improvement in joint count, joint score, joint swelling, grip strength and joint pain in patients taking the combination with no significant increase in adverse reactions. CONCLUSION: CyA in combination with gold or MTX may, over a 6 month period, increase efficacy in patients with refractory RA without significant increase in toxicity.

Contraceptive compliance with a levonorgestrel triphasic and a norethindrone monophasic oral contraceptive in adolescent patients.

OBJECTIVE: This study was undertaken to assess the impact of two low-dose oral contraceptive pills on compliance and side effects in adolescent patients. STUDY DESIGN: The use of a levonorgestrel-containing triphasic pill (N = 114) was compared with that of a monophasic (1 + 35) norethindrone-containing pill (N = 110) at two different sociodemographic sites. RESULTS: No significant difference in compliance or pill satisfaction was observed between the pills. Socioeconomic factors were the overriding predictors of compliance. At 3 and 12 months of follow-up, there were significantly fewer complaints of overall side effects (p less than 0.001 and p = 0.004, respectively), breakthrough bleeding (p = 0.017 and p = 0.018), and pill amenorrhea (p = 0.002 and p less than 0.001) among users of the triphasic pill. Mean weight change at 12 months was +1.1 kg for the monophasic pill and -0.1 kg for the triphasic pill. All known pregnancies occurred among noncompliant city clinic patients. CONCLUSIONS: Adolescents experienced fewer side effects with the triphasic pill than with the monophasic one, but compliance was the same.

Methotrexate in rheumatoid arthritis. Impact on quality of life assessed by traditional standard-item and individualized patient preference health status questionnaires.

In a double-blind, randomized trial of methotrexate vs placebo in rheumatoid arthritis, the effect of treatment on physical, social, and emotional function was measured in two different ways: the same, standard measurements in all patients, and individualized measurements selected by the patients at the start of the trial as representing the functions they most wanted to have improved by treatment. On the standard measurements, methotrexate-treated patients fared better than placebo-treated patients in their physical, social, and emotional function by 11%, 5%, and 6%, respectively, results that, although statistically significant, were small. However, methotrexate-treated patients were 29% better in the individualized measures, a result that was both highly statistically significant and greater than the differences in the standard measurements or in joint counts, grip strength, proximal interphalangeal joint circumference, morning stiffness, or walking time. Because the individualized measurements were as efficient as the best direct joint examination measures, yet reflected functional outcomes of greatest importance to individual patients, they constitute useful measures for such trials.

Solutions: The Role of the Private Practitioner.

I. Continuity and Communication II. Financial Considerations III. Adolescent Gynecology IV. Contraceptive Counseling: A Dissenting View This article discusses four subjects that are essential considerations for physicians and other health care providers to deal successfully with adolescent patients. The first focuses on the integration of adolescents into a general pediatric practice. The second section examines financial considerations in the provision of adolescent health care. The third discusses confidentiality, common problems, and adolescent sexuality as part of adolescent gynecology. The fourth section discusses contraceptive counseling and suggests that more consideration be given to those factors innate to the adolescent psyche in counseling contraceptive methods.

Estrogen deficiency in adolescents and young adults: impact on bone mineral content and effects of estrogen replacement therapy.

Because the long-term effects of estrogen replacement in adolescents with ovarian failure and hypothalamic amenorrhea have not been previously studied, we conducted a 2-year study of 35 patients to determine factors contributing to baseline bone density measures (bone density, bone mineral content, and bone width) and the response to estrogen therapy. Estrogen-deficient patients were often profoundly osteopenic by single-photon absorptiometry of the radius and dual-photon absorptiometry of the spine, despite estrogen replacement. Variables that were significant predictors of better initial single-photon absorptiometry measurements included increased age, increased body mass index, spontaneous pubertal development, lack of radiation therapy, and lower serum osteocalcin. Patients treated with estrogen/progestin had stable cortical bone mineral content and bone density at the distal one-third of the radius, a slight improvement in bone density at the distal one-tenth of the radius, and on encouraging, but marginal, improvement in the z score (standard deviation from the mean) of bone mineral content at the distal one-tenth. The z scores for cortical bone width and bone density decreased, suggesting a possible relative worsening over time. In untreated estrogen-deficient girls, bone mineral content and bone density decreased (but not significantly); the z score of cortical bone width showed a significant decrease. Using dual-photon absorptiometry, a history of radiation therapy was found to be a predictor of lower bone density compared with age-matched controls. Estrogen progestin therapy did not result in changes in serum levels of lipids and antithrombin III, weight, or blood pressure.(ABSTRACT TRUNCATED AT 250 WORDS)

Treatment with dexamethasone of androgen excess in adolescent patients.

Fourteen hirsute girls, ages 12 to 22 years (mean +/- SD: 17.2 +/- 2.6 years), in whom 21-hydroxylase deficiency was excluded by a 1-hour intravenous alpha 1-24 corticotropin test, were evaluated by a 4-day dexamethasone test and then treated with a bedtime dose of dexamethasone (0.5 mg in 10 patients, 0.25 mg in four) for 0.6 to 3.4 years (1.3 +/- 0.8 years). Hirsutism decreased in four patients, did not change in nine, and increased in one. Of the 10 patients with irregular menses, only three developed regular cycles while taking dexamethasone. During long-term dexamethasone therapy, serum levels of testosterone decreased from 102 +/- 22 to 72 +/- 27 ng/dL, free testosterone from 35 +/- 11 to 19 +/- 8 pg/mL, and dehydroepiandrosterone sulfate from 396 +/- 138 to 171 +/- 101 micrograms/dL. Although free testosterone decreased to less than 15 pg/mL in eight of 14 patients with the suppression test, only four patients had free testosterone levels less than 15 pg/mL during therapy. Two of the 14 patients have had no recurrence of hirsutism or increase in serum androgens after 28 and 29 months, respectively, after dexamethasone therapy was discontinued. Oral contraceptives were given to nine patients inadequately responsive to bedtime dexamethasone therapy. The mean percent decrease of testosterone and free testosterone levels during oral contraceptive therapy was significantly greater than during long-term treatment with dexamethasone, and hirsutism lessened in all. We conclude that a single bedtime dose of dexamethasone is satisfactory only in patients who maintain serum free testosterone values less than 15 pg/mL without side effects. For other patients, either another glucocorticoid or, in most cases, ovulation suppression should be prescribed for adolescents with progressive hirsutism and elevated androgen levels.

Adolescents' compliance with the use of oral contraceptives.

To elucidate the factors that might influence compliance with oral contraceptive use among sexually active adolescents, we undertook a study of 209 unmarried adolescents initiating use of oral contraceptives in three different settings: an inner-city adolescent clinic, a birth control clinic in a midsized industrial city, and a suburban private practice. At the three-month follow-up visit, factors associated with compliance included older age, suburban residence, white race, health care in the suburban private practice, payment status, prior use of contraception, mother's unawareness of oral contraceptives, married parents, older boyfriend, lack of worry about being pregnant, and satisfaction with pill use. Compliance at long-term follow-up (13.5 +/- 3.7 months) was additionally associated with educational goals, father's education level, and absence of side effects. Ten pregnancies occurred during the study period among noncompliant site I patients. Inner-city clinic patients were at high risk of noncompliance and unplanned pregnancy.

Low dose cyclosporine in rheumatoid arthritis: a pilot study.

A 6 month open trial of cyclosporine (CyA) was conducted in 20 patients with active rheumatoid arthritis unresponsive to second line therapy. The dosage was monitored to achieve a serum blood level of 75-150 ng/ml. A 25% reduction in ARA joint count (baseline mean 38.2; 6 month or time of CyA withdrawal mean 28.7; p less than 0.001) was observed for all patients. Fifteen completed the 6 month CyA regimen and 5 developed toxicity requiring CyA to be permanently withdrawn. For the 15 patients completing 6 months of CyA, improvement was 36% (baseline 34.7; 6 month mean 22.2; p less than 0.001). Corresponding improvements were also observed on the other main study outcomes of pain and functional ability. Improvement occurred between 12-20 weeks, somewhat later than in other studies. Toxicity included mild hypertension (4 patients) and gastrointestinal intolerance (2). Three patients were withdrawn from CyA due to nephrotoxicity. There was a clinically significant reduction in calculated creatinine clearance but this returned to baseline within 6 months after CyA was withdrawn for all except 2 patients who took 12 months to return to baseline.

Effect of parathyroid hormone on gentamicin plasma membrane binding and tissue accumulation.

Reportedly, the initiating event in the renal uptake of gentamicin is its binding to anionic, plasma membrane phospholipids. Because parathyroid hormone is known to affect phospholipid metabolism, the plasma membrane binding and tissue accumulation of gentamicin were examined as a function of the parathyroid hormone status of the animal. The experiments were conducted by evaluating the parameters in isolated brush border and basolateral membranes from control, hyper- and hypoparathyroid rats. Scatchard analysis revealed that [125I]gentamicin bound with equal affinity to either membrane to a single class of noninteracting sites. The basolateral membrane had more binding sites than did the brush border, 28 +/- 0.5 vs. 1.8 +/- 0.3 nmol/mg of protein, respectively. Neither the affinity constants nor the number of binding sites were affected by the parathyroid hormone status of the donor animal. On the other hand, in the hypoparathyroid state the amount and the rate of gentamicin accumulation were less than in the hyperparathyroid state. The difference in accumulation cannot be explained on the basis of a change in the number or affinity of the putative receptor. Therefore, the alteration must reflect some difference subsequent to the binding site.

Double-blind randomized controlled trial of isoxicam vs piroxicam in elderly patients with osteoarthritis of the hip and knee.

1 Fifty-seven elderly patients with primary osteoarthritis of the hip and knee were entered into a double-blind, randomized, controlled parallel group trail to compare the efficacy and tolerability of isoxicam (maximum = 200 mg day-1) and piroxicam (maximum = 20 mg day-1). 2 Clinical assessments were made following a 1 week NSAID-free washout period and at biweekly intervals during the next 6 weeks of active treatment. 3 The majority of patients in both groups experienced a clinically important and statistically significant therapeutic response. 4 No statistically significant between-group differences were noted with respect to drug efficacy. 5 One patient was withdrawn from the piroxicam group because of lack of effect, but there were no such withdrawals from the isoxicam group. 6 Five patients were withdrawn from the piroxicam group because of adverse reactions compared to only one withdrawal from the isoxicam group. 7 This study indicates that isoxicam is an efficacious and well-tolerated once-daily NSAID for elderly patients with osteoarthritis.

The relationships of calculated percent body fat, sports participation, age, and place of residence on menstrual patterns in healthy adolescent girls at an independent New England high school.

A prospective study was undertaken to determine normal menstrual patterns in healthy girls in an independent high school and assess the effects of exercise (type and hours per day), age (chronologic and gynecologic), calculated estimate of body fat, and place of residence (boarding and day students) on menstrual function. Three hundred twenty-seven girls (means age 15.5 +/- 1.1 years) answered a questionnaire on menstrual history; 306 (93.6%) were postmenarchal and 21 (6.4%) premenarchal. Calculated estimate of percent body fat was significantly lower in premenarchal than postmenarchal girls (22.4% versus 27.3% p less than 0.0001). Ninety-three percent of adolescents reported flow lasting 4-7 days; 59.7% dysmenorrhea; and 63% premenstrual symptoms. There was no correlation between estimated body fat or hours per day of exercise and the regularity of menses, duration of flow, or dysmenorrhea. With the exception of gymnastics and dancing, sports participation had little or no impact on menstrual patterns. Follow up questionnaires and menstrual calendars were obtained from 87 girls eight to fifteen months after the initial questionnaires. All girls whose cycles had changed from regular to irregular were boarding students, confirming previous anecdotal reports that separation from home may be a significant stress for adolescents.

Clinical evaluation of two strategies for improving patient recall of prior drug therapy.

The ability to recall details of current and prior drug therapy was evaluated in two studies employing a total of 94 patients with inflammatory polyarthritis. Ten per cent of patients were unable to completely recall the names of their current anti-inflammatory drugs and eighty-three per cent of patients to completely recall the details of prior anti-inflammatory drug therapy. Prompting firstly with the proprietary names of drugs and thereafter with a pill board substantially enhanced recall particularly for prior NSAID therapy. Nineteen per cent of responses obtained with verbal prompting were inaccurate. No such problems were encountered in responses obtained using the pill board. These findings indicate that a complete and accurate drug history can only be obtained in the majority of patients using recall enhancement strategies.

Deletion of the long arm of chromosome 11 [46,XX,del(11)(q24.1--qter)].

A child who presented at three months of age with pyloric stenosis and pancytopenia was found to have a partial deletion of the long arm of chromosome 11, del(11)(q24.1----qter). Only two previous cases have been described with an apparently identical chromosomal deletion, and both exhibit similar phenotypic features. Other patients with larger deletions of the distal region of the long arm of chromosome 11 show many features in common with these three cases. It is suggested that the region of the long arm of chromosome 11 from band q24.1 to qter may contain the genetic material responsible for the expression of the 11q - phenotype.
