Efficacy of octreotide in diarrhoea due to Vibrio cholerae: a randomized, controlled trial

The ultrastructure of autonomic nerve fibers and terminal varicosities is described in relation to the lamina propria of the human seminiferous tubules during childhood (age 3 to 10 years). Autonomic nerve varicosities are classified as: Type I with numerous small (30-60 nm) agranular vesicles and variable numbers of large (100 nm) granular vesicles, and Type II with numerous small (30-60 nm) granular vesicles and sporadic large granular vesicles. These two varicosity types are consistent in morphology with cholinergic and adrenergic nerve terminals, respectively. Nerve varicosities are found, associated with Schwann cells, in proximity to the cells of the lamina propria. Although not found in direct "synaptic' contact, these autonomic endings are often within a few hundred nanometers of the cellularity of the lamina propria. The Schwannian sheath is interrupted over the varicosities at these sites and occasionally the terminal varicosities are totally lacking a Schwann sheath. These findings are consistent with the structural relationship of autonomic nerve "terminals' and effector in other endocrine and non-endocrine systems. This is the first evidence of adrenergic nerve varicosities in proximity to the lamina propria in humans (at any age). Evidence is also presented which suggests a locational difference in the distribution of cholinergic (Type I) and adrenergic (Type II) nerve varicosities in this region, with only cholinergic endings observed directly adjacent to the basal lamina of the seminiferous tubules.     

Recombinant interferon-alpha therapy for acute hepatitis B: a randomized, double-blind, placebo-controlled trial

In spite of the availability of hepatitis B vaccine, acute hepatitis B continues to be a worldwide problem for which no specific therapy is available. We investigated the safety and the effectiveness of recombinant interferon-alpha2b (rIFN-alpha2b) in the treatment of acute hepatitis B by determining overall severity and duration of symptoms, time required to clear viral antigens and hepatitis B virus (HBV) DNA, and titre of antibodies to hepatitis B surface antigen (HBsAb), 24 weeks after the onset of therapy. One hundred patients were randomly assigned to treatment with either 3 million units (MU) (n = 34) or 10 MU (n = 33) rIFN-alpha2b or to placebo (n = 33), three times weekly for 3 weeks. Follow-up was for 24 weeks. A significantly shorter duration of the symptoms and signs of acute hepatitis was observed in patients who received 3 MU rIFN-alpha2b compared with those who received 10 MU rIFN-alpha2b or placebo. Twenty-one weeks post-therapy, patients treated with 10 MU rIFN-alpha2b showed a significantly higher geometric mean HBsAb titre than those treated with placebo (85.1 vs 35.5 IU l-1, P < 0.05). rIFN-alpha2b administration was well tolerated even in jaundiced patients. No serious side-effects were observed necessitating reduction in dose or discontinuation of the drug. The effect of rIFN-alpha2b on transition of HBV infection to chronicity could not be evaluated in this trial because such an unfavourable course was not seen in any of the treated or the control patients. In conclusion, rIFN-alpha2b was safe in acute hepatitis B, and at low dose was found to ameliorate symptoms and to shorten significantly the duration of illness.     

A randomized, controlled trial of amitriptyline in the acute treatment of adolescent major depression

OBJECTIVE: To determine amitriptyline's (AMI) efficacy in the acute treatment of adolescent major depressive disorder (MDD). METHOD: Subjects aged 12 through 17 years meeting Research Diagnostic Criteria for MDD, diagnosed with the Schedule for Affective Disorders and Schizophrenia for School-Age Children (K-SADS), participated in a 2-week placebo-washout followed by an 8-week, randomized, double-blind, parallel-design, placebo-controlled trial of AMI, 5 mg/kg per day. The K-SADS nine-item scale, the Hamilton Depression Rating Scale, and the Clinical Global Impressions rating scale were used as outcome measures. RESULTS: Thirty-one subjects were randomized (18 AMI, 13 placebo). Twenty-two subjects were study completers (12 AMI, 10 placebo). AMI's efficacy was suggested by the Clinical Global Impressions but not the K-SADS-derived data. Perhaps the primary limitation of the current study is its small sample size. CONCLUSION: No definitive recommendation can be made regarding the efficacy of tricyclic antidepressants in the treatment of adolescent MDD.     

The Nordic multicenter double-blind randomized controlled trial of prophylactic ursodeoxycholic acid in liver transplant patients

BACKGROUND: Prophylactic treatment with ursodeoxycholic acid (UDCA) has been reported to reduce the incidence of acute rejection after liver transplantation compared with historical controls. We investigated this in a prospective, randomized, placebo-controlled multicenter study. METHODS: Fifty-four liver transplant patients were allocated to the UDCA treatment group (15 mg/kg/day), and 48 patients were allocated to the placebo group. Trial medicine was started on the first postoperative day and was given for 3 months. Follow-up was for 12 months. Treatment was stratified for adults with chronic liver disease (n=77), adults with acute liver failure (n=10), and children (n=15). RESULTS: The frequency of patients with acute rejection was 65% in the UDCA treatment group and 68% in the placebo group. The frequency of steroid-resistant rejection was similar in both groups. The probability of acute rejection, analyzed according to the intention-to-treat policy with Kaplan-Meier analysis, was similar in both treatment groups. No significant differences were found in patient survival and graft survival probabilities. For the biochemical markers of cholestasis, only gamma-glutamyltransferase was significantly improved after 2 months of UDCA treatment. CONCLUSIONS: The initial optimistic report of a beneficial effect of prophylactic treatment with UDCA on acute rejection after liver transplantation was not confirmed in this controlled study.     

Ursodeoxycholic acid in the treatment of primary biliary cirrhosis: a short-term, randomized, double-blind controlled, cross-over study with long-term follow up

In order to evaluate the efficacy of ursodeoxycholic acid (UDCA) in the treatment of Chinese patients with primary biliary cirrhosis, a short-term, randomized, double-blind controlled, cross-over study was done with long-term follow up. In the first part of the study, 12 patients were randomly chosen to receive either UDCA 600 mg/day for 3 months followed by a placebo for 3 months or a placebo for 3 months followed by UDCA for 3 months. The clinical symptoms of pruritus improved when the patients were receiving UDCA but became worse when receiving a placebo. Mean serum levels of alkaline phosphatase (ALPase), gamma-glutamyl transferase (gamma-GT), total bilirubin, cholesterol, alanine aminotransferase (ALT) and aspartate aminotransferase all decreased below the baseline values when receiving UDCA treatment and all increased above the baseline values when receiving the placebo. The difference was statistically significant. In the second part of the study, 19 patients received long-term UDCA treatment (mean 20 months). The clinical symptoms of pruritus improved in 90% of the pruritic patients. Serum levels of ALPase, gamma-GT and ALT fell significantly from the pretreatment values, 6, 12 and from the mean 20 months after UDCA treatment. Serum levels of total bilirubin fell significantly 6 and 12 months after UDCA treatment but did not reach statistical significance at the last follow up. No patient lost antimitochondrial antibody and elevated immunoglobulin levels did not improve significantly, but the Mayo clinical risk score improved significantly after long-term UDCA treatment.(ABSTRACT TRUNCATED AT 250 WORDS)     

Risperidone compared with both lithium and haloperidol in mania: a double-blind randomized controlled trial

OBJECTIVE: There are many reports about the effects of prostatic intraepithelial neoplasia (PIN) on serum prostate-specific antigen (PSA) level. The aim of this study was to determine the relationship between PIN and serum free PSA/total PSA (fPSA/tPSA) ratios. METHODS: We evaluated 46 patients with PIN, 15 patients with benign prostatic hyperplasia (BPH), and 16 patients with localized prostatic carcinoma (CaP) for the amount of fPSA and tPSA with the chemiluminescent enzyme assay. RESULTS: fPSA values from BPH to high-grade PIN (PIN2 and PIN3) was increased, and then a decrease was observed from high-grade PIN to CaP. fPSA was significantly different between BPH and low-grade PIN and high-grade PIN. There was no significant difference observed between BPH and CaP. tPSA values increased from BPH to CaP. tPSA was significantly different between BPH and high-grade PIN and CaP. fPSA/tPSA ratios decreased from BPH to CaP. This ratio was significantly different between CaP and BPH and low-grade PIN. There was no significant difference between CaP and high-grade PIN. CONCLUSIONS: Our results confirm that fPSA/tPSA ratio is better at discriminating between patients with CaP and those with BPH, but not between patients with CaP and those with high-grade PIN. Due to similarities between CaP and high-grade PIN, we think that decreased fPSA/tPSA ratio obtained at the time of intial diagnosis of PIN without concurrent carcinoma could be used as predictive factors to distinguish patients in whom carcinoma will be found on subsequent biopsies from those with PIN not associated with cancer on repeat biopsy.     

Interferon-gamma in the treatment of systemic sclerosis: a randomized controlled multicentre trial

We report the results of a randomized controlled multicentre study on interferon-gamma (IFN-gamma) treatment of systemic sclerosis as determined by skin sclerosis, renal and other organ involvement, global assessment, subjective symptoms and quality of life. Forty-four patients were enrolled into the trial, 27 in the treatment group and 17 in the control group. All patients presented with type I or type II scleroderma. Twenty-nine patients (64%) finished the study. The mean duration of Raynaud's phenomenon and skin sclerosis was 15.3 and 10.8 years, respectively. The skin scores tended to improve in the treatment group (P > 0.05). Mouth aperture increased significantly from 38.5 to 47.7 mm in the treatment group (P < 0.001). Subanalysis of IFN-gamma treated patients with normalized skin sclerosis scores >/=1 showed significant improvement in both skin involvement and subjective symptoms (P < 0.05). Organ involvement improved in eight of 18 treatment patients and in three of 11 control patients. It worsened in three of 18 treatment patients and in four of 11 control patients. One control patient died due to cardiorespiratory failure during the study. No deterioration of renal function occurred during IFN-gamma treatment. There was a significant improvement in quality of life parameters in the control group but not in the treatment group. Plasma levels of neopterin increased significantly during IFN-gamma treatment but not in the control group, whereas N-terminal procollagen III peptide levels did not change in either group. There was a high frequency of mild to moderate influenza-like adverse events during IFN-gamma treatment. Only four of nine drop-out patients, however, experienced symptoms most probably associated with IFN-gamma treatment. We conclude that IFN-gamma therapy has mild beneficial effects on skin sclerosis and disease-associated symptoms in type I and II scleroderma. IFN-gamma treatment was associated with acceptable tolerability and did not induce major renal dysfunction in our patients.     

Gabapentin for the treatment of postherpetic neuralgia: a randomized controlled trial

CONTEXT: Postherpetic neuralgia (PHN) is a syndrome of often intractable neuropathic pain following herpes zoster (shingles) that eludes effective treatment in many patients. OBJECTIVE: To determine the efficacy and safety of the anticonvulsant drug gabapentin in reducing PHN pain. DESIGN: Multicenter, randomized, double-blind, placebo-controlled, parallel design, 8-week trial conducted from August 1996 through July 1997. SETTING: Sixteen US outpatient clinical centers. PARTICIPANTS: A total of 229 subjects were randomized. INTERVENTION: A 4-week titration period to a maximum dosage of 3600 mg/d of gabapentin or matching placebo. Treatment was maintained for another 4 weeks at the maximum tolerated dose. Concomitant tricyclic antidepressants and/or narcotics were continued if therapy was stabilized prior to study entry and remained constant throughout the study. MAIN OUTCOME MEASURES: The primary efficacy measure was change in the average daily pain score based on an 11-point Likert scale (0, no pain; 10, worst possible pain) from baseline week to the final week of therapy. Secondary measures included average daily sleep scores, Short-Form McGill Pain Questionnaire (SF-MPQ), Subject Global Impression of Change and investigator-rated Clinical Global Impression of Change, Short Form-36 (SF-36) Quality of Life Questionnaire, and Profile of Mood States (POMS). Safety measures included the frequency and severity of adverse events. RESULTS: One hundred thirteen patients received gabapentin, and 89 (78.8%) completed the study; 116 received placebo, and 95 (81.9%) completed the study. By intent-to-treat analysis, subjects receiving gabapentin had a statistically significant reduction in average daily pain score from 6.3 to 4.2 points compared with a change from 6.5 to 6.0 points in subjects randomized to receive placebo (P<.001). Secondary measures of pain as well as changes in pain and sleep interference showed improvement with gabapentin (P<.001). Many measures within the SF-36 and POMS also significantly favored gabapentin (P< or =.01). Somnolence, dizziness, ataxia, peripheral edema, and infection were all more frequent in the gabapentin group, but withdrawals were comparable in the 2 groups (15 [13.3%] in the gabapentin group vs 11 [9.5%] in the placebo group). CONCLUSIONS: Gabapentin is effective in the treatment of pain and sleep interference associated with PHN. Mood and quality of life also improve with gabapentin therapy.     

Short-chain fatty acids in the treatment of radiation proctitis: a randomized, double-blind, placebo-controlled, cross-over pilot trial

PURPOSE: Treatment of chronic radiation proctitis remains unsatisfactory. Short-chain fatty acids are the preferred energy source for the colonic epithelium. We aimed to determine for the first time whether topical butyric acid enemas relieve symptoms and improve the macroscopic and microscopic findings in chronic radiation proctitis. METHODS: A randomized, double-blind, placebo-controlled, cross-over pilot trial compared patients given two weeks of butyric acid enemas (40 mmol) twice per day with those given placebo, with a one-week washout period; 15 patients were randomized and 12 completed both arms of the trial. A total symptom score combined six symptom items per week (rectal pain, episodes of rectal bleeding, amount of blood passed, days with diarrhea, number of stools, and urgency). Symptom, endoscopic, and histologic scores were obtained at the beginning of the study and again at the last week of each treatment arm. RESULTS: Total symptom score at baseline (median, 5.5) improved for those patients receiving active treatment (median, 3.5), but compared with placebo (median, 4.5), the change was not significant. Endoscopic appearances were largely unaltered by active treatment. Histology was abnormal in 82 percent of patients receiving placebo compared with 55 percent of those given butyric acid enemas (P = not significant). CONCLUSION: Butyric acid enemas do not appear to be superior to placebo in the treatment of chronic radiation proctitis.     

Spinal manipulation in the treatment of episodic tension-type headache: a randomized controlled trial

CONTEXT: Episodic tension-type headache is common and is often treated using manual therapies. Few data exist for the efficacy of these interventions. OBJECTIVE: To determine the effects of spinal manipulation therapy on adults with episodic tension-type headache. DESIGN: Randomized controlled trial lasting 19 weeks. SETTING: Outpatient facility of a National Health Service-funded chiropractic research institution in Denmark. PARTICIPANTS: Volunteer sample of 26 men and 49 women aged 20 to 59 years who met the diagnostic criteria for episodic tension-type headache as defined by the International Headache Society. INTERVENTION: Participants were randomized into 2 groups, 1 receiving soft tissue therapy and spinal manipulation (the manipulation group), and the other receiving soft tissue therapy and a placebo laser treatment (the control group). All participants received 8 treatments over 4 weeks; all treatments were performed by the same chiropractor. MAIN OUTCOME MEASURES: Daily hours of headache, pain intensity per episode, and daily analgesic use, as recorded in diaries. RESULTS: Based on intent-to-treat analysis, no significant differences between the manipulation and control groups were observed in any of the 3 outcome measures. However, by week 7, each group experienced significant reductions in mean daily headache hours (manipulation group, reduction from 2.8 to 1.5 hours; control group, reduction from 3.4 to 1.9 hours) and mean number of analgesics per day (manipulation group, reduction from 0.66 to 0.38; control group, reduction from 0.82 to 0.59). These changes were maintained through the observation period. Headache pain intensity was unchanged for the duration of the trial. CONCLUSION: As an isolated intervention, spinal manipulation does not seem to have a positive effect on episodic tension-type headache.     

Albendazole for treatment and prophylaxis of microsporidiosis due to Encephalitozoon intestinalis in patients with AIDS: a randomized double-blind controlled trial

STUDY OBJECTIVES: To determine whether obese, apparently healthy individuals experience dyspnea at rest and, if so, whether their pulmonary function test (PFT) profile and maximal respiratory pressures are different from obese, healthy subjects without dyspnea. DESIGN: Prospective, open. SETTING: Pulmonary function test laboratory, Veterans Administration Medical Center. PATIENTS: Twenty-three obese male subjects (each with a body mass index [BMI] of > 28 kg/m2) with an FEV1 level and an FEV1/FVC ratio > or = 80% of predicted and no coexisting conditions. Fifteen complained of dyspnea, where eight denied having it, at rest. MEASUREMENTS AND RESULTS: Standard PFT parameters and maximum static inspiratory (P(Imax)) and expiratory (P(Emax)) mouth pressures were determined. Subjects with dyspnea had similar age and height but larger body weight (113.9+/-5.0 vs 97.4+/-2.6 kg, p = 0.03) and BMI (37.4+/-1.6 vs 31.8+/-0.7 kg/m2, p = 0.02) than subjects without dyspnea, and a greater number of them were current or previous smokers. Forced expiratory flow at 75% vital capacity (54.9+/-6 vs 75.5+/-7% predicted, p = 0.05), maximum voluntary ventilation (MVV; 90.2+/-3.8 vs 107.8+/-9.3% predicted, p = 0.05), and P(Emax) (77+/-2 vs 97.8% predicted, p = 0.007) were significantly reduced in the group of subjects with dyspnea. Large airway function (FVC, FEV1, and FEV1/FVC ratio), lung volumes, and gas exchange parameters were similar between the two groups. CONCLUSIONS: Some obese, but otherwise healthy, individuals experience dyspnea at rest. Reduced P(Emax) and MVV combined with greater body mass and peripheral airway disease are most likely responsible for the sensation of dyspnea in these individuals.     

Long-term stimulant treatment of children with attention-deficit hyperactivity disorder symptoms. A randomized, double-blind, placebo-controlled trial

In this study we evaluated the effect of long-term melatonin (MEL) treatment on the cytotoxic activity and number of natural killer (NK) cells and the proliferative response of spleen lymphocytes to phytohemagglutinin (PHA) or interleukin-2 (IL-2) in old mice. Seventeen-eighteen month-old Balb/c mice were supplemented with MEL (40-50 microg/day/mouse) and sacrificed after eight months. The MEL supplementation was unable to recover the low levels of both endogenous and IL-2-induced NK cell activity found in old untreated mice. Also the NK cell number was unaffected by MEL treatment. The spleen lymphocyte proliferative response to both PHA and IL-2 was not different in old MEL-treated compared to old untreated mice. These results indicate that long-term MEL supplementation does not recover the age-related deterioration of NK cell activity and lymphocyte proliferative capacity.     

Effects of silymarin in alcoholic patients with cirrhosis of the liver: results of a controlled, double-blind, randomized and multicenter trial

BACKGROUND/AIMS: Silymarin has protective effects in different experimental conditions, but its efficacy in human liver cirrhosis has not been completely established. Therefore, this study was carried out to determine the effect of silymarin in alcoholics with liver cirrhosis with respect to survival and clinical and laboratory changes. METHODS: From February 1986 to June 1989, we enrolled 200 alcoholics with histologically or laparoscopically proven liver cirrhosis in a randomized, double-blind multicenter trial comparing 450 mg of silymarin (150 mg/ three times per day) with placebo. The primary outcome was time to death, and the secondary outcome was the progression of liver failure. Additional analyses were also performed in 75 patients in whom anti-hepatitis C virus antibodies were measured after completion of the trial. RESULTS: One hundred and three patients were assigned to receive silymarin and 97 to receive placebo. The two groups were well matched for demographic and baseline clinical and laboratory features. A 2-year study period was completed in 125 patients (57 receiving silymarin and 68 receiving placebo). Twenty-nine patients (15 receiving silymarin, and 14 receiving placebo) died during the trial. Survival was similar in patients receiving silymarin or placebo. The effect of silymarin on survival was not influenced by sex, the persistence of alcohol intake, the severity of liver dysfunction or by the presence of alcoholic hepatitis in the liver biopsy. Silymarin did not have any significant effect on the course of the disease. No relevant side-effects were observed in any group. CONCLUSIONS: The results of this study indicate that silymarin has no effect on survival and the clinical course in alcoholics with liver cirrhosis.     

Zinc gluconate lozenges for treating the common cold in children: a randomized controlled trial

CONTEXT: The common cold is one of the most frequently occurring illnesses and is responsible for substantial morbidity and economic loss. Biochemical evidence suggests that zinc may be an effective treatment, and zinc gluconate glycine (ZGG) lozenges have been shown to reduce the duration of cold symptoms in adults. OBJECTIVE: To determine the efficacy of ZGG treatment of colds in children and adolescents. DESIGN: A randomized, double-masked, placebo-controlled study. SETTING: Two suburban school districts in Cleveland, Ohio. PATIENTS: A total of 249 students in grades 1 through 12 were enrolled within the first 24 hours of experiencing at least 2 of 9 symptoms of the common cold. INTERVENTION: Zinc lozenges, 10 mg, orally dissolved, 5 times a day (in grades 1-6) or 6 times a day (in grades 7-12). MAIN OUTCOME MEASURES: Time to resolution of cold symptoms based on subjective daily symptom scores for cough, headache, hoarseness, muscle ache, nasal congestion, nasal drainage, scratchy throat, sore throat, and sneezing. RESULTS: Time to resolution of all cold symptoms did not differ significantly between students receiving zinc (n = 124) and those receiving placebo (n = 125) (median, 9 days; 95% confidence interval [CI], 8-9 days; median, 9 days, 95% CI, 7-10 days, respectively; P=.71). There were no significant differences in the time to resolution of any of the 9 symptoms studied. Compared with controls, more students in the zinc group reported adverse effects (88.6% vs 79.8%; P=.06); bad taste (60.2% vs 37.9%; P=.001); nausea (29.3% vs 16.1%; P=.01); mouth, tongue, or throat discomfort (36.6% vs 24.2%; P=.03); and diarrhea (10.6% vs 4.0%; P=.05). CONCLUSIONS: In this community-based, randomized controlled trial, ZGG lozenges were not effective in treating cold symptoms in children and adolescents. Further studies with virologic testing are needed to clarify what role, if any, zinc may play in treating cold symptoms.     

A double-blind, randomized, placebo-controlled trial of fluoxetine in children and adolescents with depression

BACKGROUND: Depression is a major cause of morbidity and mortality in children and adolescents. To date, randomized, controlled, double-blind trials of antidepressants (largely tricyclic agents) have yet to reveal that any antidepressant is more effective than placebo. This article is of a randomized, double-blind, placebo-controlled trial of fluoxetine in children and adolescents with depression. METHODS: Ninety-six child and adolescent outpatients (aged 7-17 years) with nonpsychotic major depressive disorder were randomized (stratified for age and sex) to 20 mg of fluoxetine or placebo and seen weekly for 8 consecutive weeks. Randomization was preceded by 3 evaluation visits that included structured diagnostic interviews during 2 weeks, followed 1 week later by a 1-week, single-blind placebo run-in. Primary outcome measurements were the global improvement of the Clinical Global Impressions scale and the Children's Depression Rating Scale--Revised, a measure of the severity depressive symptoms. RESULTS: Of the 96 patients, 48 were randomized to fluoxetine treatment and 48 to placebo. Using the intent to treat sample, 27 (56%) of those receiving fluoxetine and 16 (33%) receiving placebo were rated "much" or "very much" improved on the Clinical Global Impressions scale at study exit (chi 2 = 5.1, df = 1, P = .02). Significant differences were also noted in weekly ratings of the Children's Depression Rating Scale--Revised after 5 weeks of treatment (using last observation carried forward). Equivalent response rates were found for patients aged 12 years and younger (n = 48) and those aged 13 years and older (n = 48). However, complete symptom remission (Children's Depression Rating Scale--Revised < or = 28) occurred in only 31% of the fluoxetine-treated patients and 23% of the placebo patients. CONCLUSION: Fluoxetine was superior to placebo in the acute phase treatment of major depressive disorder in child and adolescent outpatients with severe, persistent depression. Complete remission of symptoms was rare.     

Effects of docosahexaenoic acid on serum lipoproteins in patients with combined hyperlipidemia: a randomized, double-blind, placebo-controlled trial

OBJECTIVE: The objective of this study was to evaluate the effects of daily dietary supplementation with 1.25 g or 2.5 g of docosahexaenoic (DHA), in the absence of eicosapentaenoic acid (EPA), on serum lipids and lipoproteins in persons with combined hyperlipidemia (CHL) [serum low-density lipoprotein cholesterol (LDL-C) 130 to 220 mg/dL and triglycerides 150 to 400 mg/dL]. METHODS: After a 6-week dietary stabilization period, subjects entered a 4-week single-blind placebo (vegetable oil) run-in phase. Those with adequate compliance during the the run-in were randomized into one of three parallel groups (placebo, 1.25, or 2.5 g/day DHA) for 6 weeks of treatment. Supplements were administered in a triglyceride form contained in gelatin capsules. Primary outcome measurements were plasma phospholipid DHA content, serum triglycerides, high-density lipoprotein cholesterol (HDL-C). LDL-C and non-HDL-C. RESULTS: The DHA content of plasma phospholipids increased dramatically (2 to 3 fold) in a dose-dependent manner. Significant (p < 0.05) changes were observed in serum triglycerides (17 to 21% reduction) and HDL-C (6% increase) which were of similar magnitude in both DHA groups. Non-HDL-C [+1.6 (NS) and +5.7% (p < 0.04)] and LDL-C [+9.3% (NS) and +13.6% (p < 0.001)] increased in the DHA treatment groups. All lipid effects reached an apparent steady state within the first 3 weeks of treatment. CONCLUSION: Dietary DHA, in the absence of EPA, can affect lipoprotein cholesterol and triglyceride levels in patients with combined hyperlipidemia. The desirable triglyceride and HDL-C changes were present at a dose which did not significantly increased non-HDL-C or LDL-C. These preliminary findings suggest that dietary supplementation with 1.25 g DHA/day, provided in a triglyceride form, may be an effective tool to aid in the management of hypertriglyceridemia.     

Comparison of flutamide and spironolactone in the treatment of hirsutism: a randomized controlled trial

OBJECTIVE: To compare the clinical efficacy and safety of the pure antiandrogen flutamide and the steroidal derivative spironolactone in the treatment of hirsutism in women. DESIGN: Fifty-three premenopausal women suffering from moderate to severe hirsutism were randomized into two groups and received either flutamide or spironolactone in association with a triphasic oral contraceptive (OC) pill. Hirsutism, acne, seborrhea, alopecia, and side effects were monitored monthly for a treatment period of 9 months and a follow-up after treatment period of 6 months. Blood samples were taken at each visit for assessment of endocrine, biochemical, and hematologic parameters. RESULTS: After only 6 months of therapy, flutamide caused a maximal reduction in the hirsutism score to a value within almost normal range; during the same period, spironolactone caused only a 30% reduction of the hirsutism score. Whereas flutamide caused a dramatic (80%) decrease in total acne, seborrhea, and hair loss score after only 3 months of therapy, spironolactone caused only a 50% reduction in acne and seborrhea, with no significant effect on the hair loss score. Four patients in the spironolactone group but only one in the flutamide group stopped the medication because of adverse side effects. CONCLUSION: The present data obtained in a randomized prospective study clearly demonstrate that the pure antiandrogen flutamide is superior to spironolactone in the treatment of female hirsutism and its related androgen-dependent symptoms and signs in women.     

A randomized, double-blind crossover trial of fluoxetine and amitriptyline in the treatment of fibromyalgia

OBJECTIVE: To study the effect of fluoxetine (FL) and amitriptyline (AM), alone and in combination, in patients with fibromyalgia (FM). METHODS: Nineteen patients with FM completed a randomized, double-blind crossover study, which consisted of 4 6-week trials of FL (20 mg), AM (25 mg), a combination of FL and AM, or placebo. Patients were evaluated on the first and last day of each trial period. Outcome measures included a tender point score, the Fibromyalgia Impact Questionnaire (FIQ), the Beck Depression Inventory (BDI) scale, and visual analog scales (VAS) for global well-being (1 completed by the physician and 1 by the patient), pain, sleep trouble, fatigue, and feeling refreshed upon awakening. RESULTS: Both FL and AM were associated with significantly improved scores on the FIQ and on the VAS for pain, global well-being, and sleep disturbances. When combined, the 2 treatments worked better than either medication alone. Similar, but nonsignificant, improvement occurred in the BDI scale, the physician global VAS, and the VAS for fatigue and feeling refreshed upon awakening. Trends were less clear for the tender point score. CONCLUSION: Both FL and AM are effective treatments for FM, and they work better in combination than either medication alone.     

Mifepristone in combination with methotrexate for the medical treatment of tubal pregnancy: a randomized, controlled trial

In the search for a more potent alternative to a single i.m. injection of methotrexate for ectopic pregnancy, a randomized trial was organized. The efficacy of a combination of methotrexate and mifepristone was compared with methotrexate alone in the treatment of unruptured tubal pregnancies. The diagnosis of an unruptured tubal pregnancy was confirmed laparoscopically in 50 patients during a 2 year period. Women were randomized to receive a single i.m. injection of 50 mg/m2 methotrexate alone or a single dose of 600 mg oral mifepristone in combination with the same dose of methotrexate. Both treatment protocols were successful in achieving the resolution of unruptured ectopic pregnancy (18/25 in the methotrexate group and 22/25 in the combination group) following the initial intervention. A second injection was needed in four (16%) cases in the methotrexate group and in one (4%) case in the combination group. Overall, a complete resolution was achieved in 22/25 and 23/25 cases respectively. Unruptured ectopic pregnancy resolved faster in women given the combination of methotrexate and mifepristone compared to women given methotrexate only (P = 0.01). The effect of the methotrexate and mifepristone combination was more pronounced in women with higher human chorionic gonadotrophin concentrations.
