Continuous venovenous haemodiafiltration versus intermittent haemodialysis for acute renal failure in patients with multiple-organ dysfunction syndrome: a multicentre randomised trial.

BACKGROUND: Whether continuous renal replacement therapy is better than intermittent haemodialysis for the treatment of acute renal failure in critically ill patients is controversial. In this study, we compare the effect of intermittent haemodialysis and continuous venovenous haemodiafiltration on survival rates in critically ill patients with acute renal failure as part of multiple-organ dysfunction syndrome. METHODS: Our prospective, randomised, multicentre study took place between Oct 1, 1999, and March 3, 2003, in 21 medical or multidisciplinary intensive-care units from university or community hospitals in France. Guidelines were provided to achieve optimum haemodynamic tolerance and effectiveness of solute removal in both groups. The two groups were treated with the same polymer membrane and bicarbonate-based buffer. 360 patients were randomised, and the primary endpoint was 60-day survival based on an intention-to-treat analysis. FINDINGS: Rate of survival at 60-days did not differ between the groups (32% in the intermittent haemodialysis group versus 33% in the continuous renal replacement therapy group [95 % CI -8.8 to 11.1,]), or at any other time. INTERPRETATION: These data suggest that, provided strict guidelines to improve tolerance and metabolic control are used, almost all patients with acute renal failure as part of multiple-organ dysfunction syndrome can be treated with intermittent haemodialysis.

Catheter ablation for symptomatic atrial fibrillation (PVI-SHAM-AF): a randomised, double-blind, sham-controlled, multicentre trial.

BACKGROUND: Guidelines recommend catheter ablation for symptom relief in patients with atrial fibrillation. The aim of this trial was to ascertain whether catheter ablation improves atrial fibrillation-related quality of life more than a sham procedure. METHODS: PVI-SHAM-AF was a double-blind, multicentre, randomised trial conducted at nine study sites in Germany and Poland. Patients aged 18 years or older with symptomatic paroxysmal or persistent atrial fibrillation were randomly assigned in a 2:1 ratio to catheter ablation or a sham procedure using an automated online randomisation system with variable block sizes, stratified by trial site. The primary endpoint was the between-group difference in change from baseline to 6 months in the Atrial Fibrillation Effect on the Quality-of-life Questionnaire (AFEQT) summary score. The prespecified primary analysis was done in the intention-to-treat population and included all randomly assigned patients, with missing data handled by multiple imputation. This trial is registered with ClinicalTrials.gov (NCT05119231) and 12-month follow-up is ongoing. FINDINGS: Between Nov 12, 2021, and Nov 3, 2025, 1199 patients were invited to participate in the study and 262 patients consented and were randomly assigned: 173 patients to catheter ablation and 89 to sham. The median age was 67 years (IQR 62-73); 134 (51%) were female and 128 (49%) were male. Median follow-up was 184 days (IQR 181-191). At 6 months, the mean AFEQT summary score had increased from 61·3 (SD 20·1) to 81·1 (16·6) in the catheter ablation group and from 59·2 (19·0) to 74·9 (19·5) in the sham control group. The Hodges-Lehmann estimate of the between-group difference in change was 2·6 (95% CI -2·7 to 8·0; p=0·36). One death occurred in each group; neither was considered related to the study procedure. Serious adverse events adjudicated as related or possibly related to the study procedure occurred in ten unique patients: six patients in the catheter ablation group and four patients in the sham control group. One of these was an ischaemic stroke occurred in the sham control group. INTERPRETATION: Catheter ablation did not demonstrate superiority over a sham procedure for improving atrial fibrillation-related quality of life at 6 months.

Multicentre trial of ethamsylate for prevention of periventricular haemorrhage in very low birthweight infants.

The effectiveness of ethamsylate in the prevention of periventricular haemorrhage (PVH) in very low birthweight infants was evaluated by means of a multicentre, placebo-controlled, double-blind trial. In 330 infants without evidence of PVH on initial cranial ultrasound examination there was little difference between ethamsylate and placebo groups with respect to subependymal haemorrhage, but intraventricular and parenchymal haemorrhages developed in 30/162 infants (18.5%) in the treated group, compared with 50/168 (29.8%) in the control group (p less than 0.02). The incidence of intraventricular and parenchymal haemorrhage in survivors was 20/137 (14.6%) in the ethamsylate group and 37/146 (25.3%) in the controls (p less than 0.05). In 30 infants with evidence of PVH on the initial scan, ethamsylate treatment seemed to limit parenchymal extension. Analysis of the total cohort of 360 infants showed that the proportion of infants in whom an increase of two or more grades of severity of PVH was recorded during the trial was lower in the treated than in the placebo group (p less than 0.01). No adverse effects were attributed to ethamsylate therapy. The reported incidence of patent ductus arterious was lower in the treated than in the placebo group (p less than 0.02). Mortality was similar in the two groups.

Multicentre double-blind study of effect of intrathecally administered natural human fibroblast interferon on exacerbations of multiple sclerosis.

In this randomised, double-blind, placebo-controlled, 2-year multicentre study intrathecally administered natural human fibroblast interferon (IFN-B) was effective in reducing exacerbations of multiple sclerosis (MS) in patients with exacerbating/remitting disease. The mean reduction in exacerbation rate of 34 patients who received IFN-B (recipients) was significantly greater during the study than that of 35 patients who received placebo (p less than 0.04). The prestudy exacerbation rates were comparable in recipients and controls, but the rate at the end of the study was significantly lower in recipients than in controls (p less than 0.001). IFN-B was given by nine or ten lumbar punctures over the first 6 months of the study, and patient observations continued for 2 years. IFN-B was well tolerated in 95% of the recipients, and the side-effects experienced were clearly acceptable for the benefits achieved. Low doses of indomethacin reduced the toxicity of IFN-B and played an important role in successful double-blinding.

Safety and tolerability of dobutamine-atropine stress echocardiography: a prospective, multicentre study. Echo Dobutamine International Cooperative Study Group.

Diagnostic tests that are hazardous or infeasible, or both, may become accepted before inadequacies are recognised; only multicentre trials can provide the necessary information for an unrestricted acceptance of any new diagnostic procedure. We prospectively studied the results obtained in 24 experienced echocardiography laboratories. 2949 tests were done in 2799 patients. In 341 tests (12% of the overall population, 21% of the negative tests) the test could not be completed because of complex ventricular tachyarrhythmias (134, 38% of all submaximal studies); nausea and/or headache (71, 20%); hypotension and/or bradycardia (62, 17%); supraventricular tachyarrhythmias (44, 12%); hypertension (24, 7%); and others (20, 6%). Dangerous events (life-threatening complications or side-effects requiring specific treatment and lasting more than 3 hours, or new hospital admission) occurred in 14 cases (1 every 210 tests)--9 cardiac (3 ventricular tachycardias; 2 ventricular fibrillations; 2 myocardial infarctions; 1 prolonged antidote-resistant myocardial ischaemia; 1 severe, persistent hypotension) and 5 extracardiac (atropine poisoning with hallucinations lasting several hours in the absence of either myocardial ischaemia or hypotension). Life-threatening and/or longlasting complications may occur during dobutamine/atropine stress echocardiography. The test is generally well tolerated, although may be interrupted by minor, self-limiting, usually symptomless side-effects.

Randomised trial of preventive nasal ventilation in Duchenne muscular dystrophy. French Multicentre Cooperative Group on Home Mechanical Ventilation Assistance in Duchenne de Boulogne Muscular Dystrophy.

Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy in children. Paralysis of respiratory muscles causes a decrease in forced vital capacity (FVC) from age 12 years, and death occurs between 20 and 25 years old and is usually related to respiratory insufficiency. Uncontrolled studies suggest that early home use of nasal intermittent positive-pressure ventilation (NIPPV) in DMD patients free of respiratory failure could limit progression of the restrictive syndrome and therefore improve survival because efficacy of preventive NIPPV has not been demonstrated in a controlled trial, we undertook a randomised multicentre study in which 70 patients with DMD were included. Patients were free of daytime respiratory failure and FVC was between 20 and 50% of predicted values. At least 6 h of nocturnal NIPPV (n = 35) was compared with conventional treatment (n = 35). During a mean follow-up of 52 months, 10 patients died, 8 in the NIPPV group and 2 in the control group (p = 0.05, log-rank test). No differences were observed between the two groups for occurrence of hypercapnia, decrease of FVC below 20% of initial values, or use of necessary mechanical ventilation. Preventive NIPPV did not improve respiratory handicap and reduced survival of DMD patients. Use of NIPPV for preventive purposes should be avoided in patients with FVC between 20 and 50% of predicted values.

Multicentre prospective controlled study of Barrett's oesophagus and colorectal adenomas. Groupe d'Etude de l'Oesophage de Barrett.

Previous studies have suggested that patients with Barrett's oesophagus may be at increased risk of colorectal neoplasia, though the association is disputed. In a multicentre prospective study we compared the prevalence of colorectal adenomas in patients with Barrett's oesophagus and controls. Barrett's oesophagus patients (n = 104) had histological confirmation of columnar epithelium extending more than 3 cm above the gastro-oesophageal junction. The 537 controls were patients with symptoms suggesting irritable bowel syndrome. No participant had a personal history of colonic neoplasm. Each patient underwent colonoscopy. Histologically proven adenomas were found in 26 Barrett's patients (25%) and 75 controls (14%). Three colorectal cancers were discovered in each group. The prevalence of adenomas was greater in the Barrett's oesophagus group than in the control group (p < 0.01) but the relation became non-significant after adjustment for age and sex and control for other known risk factors by a logistic regression model (odds ratio 1.4 [0.7-2.7]). The relative risk of adenoma was significantly higher in patients older than 59 than in younger patients (2.2 [1.3-3.5]) and in men than in women (3.4 [2.0-5.7]). Other factors contributing significantly to the risk of adenoma were a family history of colorectal cancer (2.3 [1.1-4.8]), rectal bleeding (2.1 [1.1-3.9]), previous colonic investigation (0.3 [0.1-0.7]), and complete as opposed to partial colonoscopy (6.4 [0.8-48.3]). We conclude that Barrett's oesophagus is not an independent risk factor for colorectal neoplasia and, therefore, is not, in itself an indication for colorectal screening.

Randomised multicentre study of a low-protein diet on the progression of chronic renal failure in children. European Study Group of Nutritional Treatment of Chronic Renal Failure in Childhood.

BACKGROUND: Some studies have suggested that a low-protein diet slows the deterioration of renal function in patients with chronic renal failure (CRF). The effects of a low-protein diet on renal function and growth, have not been assessed in a large, prospective randomised trial in children with CRF. METHODS: A 2-year prospective, stratified, and randomised multicentre study recruited 191 patients aged 2-18 years. After a run-in period of at least 6 months, patients were stratified into either a progressive or non-progressive category based on the change in creatinine clearance in this period. The patients were also stratified into three renal-disease categories and then randomly assigned to a control or diet group. In the diet group, the protein intake was the lowest, safe WHO recommendation--i.e., 0.8-1.1 g/kg daily adjusted for age. All patients were advised to have a calorie intake of at least 70% of the WHO recommendations. Glomerular filtration rate (GFR) was measured every 2 months by creatinine clearance; dietary compliance was checked by urinary urea-nitrogen excretion and dietary diaries (weighing method). 112 patients completed an optional third year of the study. FINDINGS: The low-protein diet did not affect growth. However, there was no effect of diet on the mean decline in creatinine clearance over 2 years (diet vs control: progressive group -9.7 [SD 8.0] vs -10.7 [11.8] mL/min per 1.73 m2; non-progressive group -2.5 [7.5] vs -4.3 [10.0] mL/min per 1.73 m2). Patients classified as having progressive disease were older and had a lower creatinine clearance and a higher blood pressure at randomisation, and had a greater decrease in creatinine clearance than non-progressive patients. On multivariate regression analysis proteinuria (partial R2 = 0.259) and systolic blood pressure (partial R2 = 0.087) were independent predictors of the change in GFR. Similar results were found after the study was extended for a third year. INTERPRETATION: A low-protein diet for 3 years did not affect the decrease in renal function in children with CRF. Proteinuria and blood pressure explain a large part of the variability of, and may be causally related to the decline in the GFR.

Association between schizophrenia and T102C polymorphism of the 5-hydroxytryptamine type 2a-receptor gene. European Multicentre Association Study of Schizophrenia (EMASS) Group.

BACKGROUND: An association between schizophrenia and the T102C polymorphism of the gene for 5-hydroxytryptamine type 2a (5-HT2a) receptor has been reported; the proportion of allele 2 of this polymorphism is higher than expected among schizophrenic patients. We looked for an association between schizophrenia and this variant of the 5-HT2a-receptor gene in a large multicentre study. METHODS: Seven countries recruited 1210 participants: 571 white schizophrenic patients and 639 ethnically matched controls. All patients had a diagnosis of schizophrenia or schizoaffective disorder. High-molecular-weight DNA was isolated from lymphocytes. PCR amplification and restriction enzyme digestion was used to examine sequence variation of the 5-HT2a-receptor gene. Genotypes 1/1, 1/2, and 2/2 were assigned. Woolf's method was used to look for an association between schizophrenia and allele 2 and the 2/2 genotype. FINDINGS: We found a significant overall association between schizophrenia and allele 2 with an odds ratio of 1.3 (95% Cl 1.1-1.53, p = 0.003). No evidence for heterogeneity was observed between samples. We found a highly significant excess of the 1-2/2-2 genotypes in schizophrenia (p = 0.008) with a relative risk of 1.7 (1.22-2.36) and an attributable fraction of 0.35. INTERPRETATION: Our findings suggest that the gene for 5-HT2a-receptor, or a locus in linkage disequilibrium with it, confers susceptibility to schizophrenia. Allele 2 is common in the population and it is, therefore, likely that this variant, or a nearby polymorphism, may affect a significant proportion of schizophrenic patients.

Multicentre prospective randomised trial of fludarabine versus cyclophosphamide, doxorubicin, and prednisone (CAP) for treatment of advanced-stage chronic lymphocytic leukaemia. The French Cooperative Group on CLL.

BACKGROUND: Fludarabine seems to be a promising treatment for patients with advanced chronic lymphocytic leukaemia (CLL). We compared fludarabine therapy with the combination of cyclophosphamide, doxorubicin, and prednisone (CAP) for treatment of CLL in a randomised, multicentre prospective trial. METHODS: Patients older than 18 years of age were entered into the study if they presented with previously untreated B-cell lineage CLL (B-CLL) of Binet stages B or C or relapsed B-CLL pretreated with chorambucil or similar non-anthracycline-containing regimens. Patients were randomly assigned to either fludarabine (25 mg/m2 per day on days 1-5) or CAP (cyclophosphamide 750 mg/m2 per day and doxorubicin 50 mg/m2 per day on day 1, and prednisone 40 mg/m2 per day on days 1-5), both given for six courses. FINDINGS: Of 196 evaluable patients, 100 were previously untreated whereas 96 patients had received prior therapy. Remission rates were significantly higher after fludarabine than CAP, with overall response rates of 60% and 44%, respectively (p = 0.023). A higher response rate to fludarabine was observed in both untreated (71% vs 60%, p = 0.26) and pretreated (48% vs 27%, p = 0.036) cases, although the difference was statistically significant only in pretreated cases. In the latter group, remission duration and survival did not differ between treatment groups with a median remission duration of 324 days after fludarabine and 179 days after CAP (p = 0.22) and median survival times of 728 days and 731 days, respectively. In untreated cases, on the other hand, fludarabine induced significantly longer remissions than CAP with the median not yet reached after fludarabine and a median of 208 days after CAP (p < 0.001). This effect also translated into a tendency towards longer overall survival after fludarabine (p = 0.087). Treatment-associated side-effects consisted in both regimens of predominantly myelosuppression and in particular granulocytopenia. CAP-treated patients had a higher frequency and severity of nausea and vomiting (25% vs 5%, p < 0.001) and alopecia (65% vs 2%, p < 0.001). INTERPRETATION: Fludarabine provided an effective and well-tolerated therapy for patients with advanced CLL, which compared favourably with CAP as one of the most effective standard regimens. In second-line therapy, fludarabine induced a significantly higher rate of complete and partial remissions, while in first-line therapy a significant prolongation of remission was obtained, which may translate into an improvement of overall survival.

Randomised multicentre trial of chronotherapy with oxaliplatin, fluorouracil, and folinic acid in metastatic colorectal cancer. International Organization for Cancer Chronotherapy.

BACKGROUND: The efficacy of chemotherapy may be affected by circadian rhythms. Therefore, we tested chronomodulated infusion (administered to coincide with relevant circadian rhythms) of oxaliplatin, fluorouracil, and folinic acid compared with a constant-rate infusion method. The combination of three drugs was delivered for 5-day courses with 16-day intervals. METHODS: We expected chronotherapy to increase objective response rate by 20% compared with constant-rate infusion. We tested this effect in a randomised multicentre trial involving patients with previously untreated metastases from colorectal cancer who were enrolled at nine institutions in three countries. 93 patients were assigned chronotherapy and 93 were assigned constant-rate infusion via multichannel programmable ambulatory pumps. The trial was interrupted when a significant difference in main outcome was reached. All data were analysed by intention to treat. FINDINGS: On enrollment, we found significant imbalances in two characteristics-abdominal gland or bone metastases (constant-rate infusion two patients, chronotherapy ten patients) and relapse from surgically treated metastases (constant-rate infusion seven patients, chronotherapy 22 patients). An objective response was obtained in 47 (51%) of the chronotherapy group, and in 27 (29%) of the constant-rate group (difference 21.5% [95% CI 13.7-31.2], p = 0.003). Chronotherapy reduced five-fold the rate of severe mucosal toxicity (14% vs 76%, p < 0.0001) and halved that of functional impairment from peripheral sensitive neuropathy (16% vs 31%, difference 15.0% [9.5-25.7], p < 0.01). Median time to treatment failure was 6.4 months on chronotherapy and 4.9 months on constant-rate infusion (p = 0.006), and 24% of the patients from the constant-rate infusion group received chronotherapy after failure. With a minimum follow-up of 3 years, median survival times and 3-year survival were similar in both groups (15.9 vs 16.9 months and 22% vs 21%, respectively). INTERPRETATION: Chronotherapy was significantly less toxic and more effective than constant-rate infusion. The results support the concept of temporal selectivity of cancer chemotherapy.

International multicentre pooled analysis of late postnatal mother-to-child transmission of HIV-1 infection. Ghent International Working Group on Mother-to-Child Transmission of HIV.

BACKGROUND: An understanding of the risk and timing of mother-to-child transmission of HIV-1 in the postnatal period is important for the development of public-health strategies. We aimed to estimate the rate and timing of late postnatal transmission of HIV-1. METHODS: We did an international multicentre pooled analysis of individual data from prospective cohort studies of children followed-up from birth born to HIV-1-infected mothers. We enrolled all uninfected children confirmed by HIV-1-DNA PCR, HIV-1 serology, or both. Late postnatal transmission was taken to have occurred if a child later became infected. We calculated duration of follow-up for non-infected children from the time of negative diagnosis to the date of the last laboratory follow-up, or for infected children to the mid-point between the date of last negative and first positive results. We stratified the analysis for breastfeeding. FINDINGS: Less than 5% of the 2807 children in four studies from industrialised countries (USA, Switzerland, France, and Europe) were breastfed and no HIV-1 infection was diagnosed. By contrast, late postnatal transmission occurred in 49 (5%) of 902 children in four cohorts from developing countries, in which breastfeeding was the norm (Rwanda [Butare and Kigali], Ivory Coast, Kenya), with an overall estimated risk of 3.2 per 100 child-years of breastfeeding follow-up (95% CI 3.1-3.8), with similar estimates in individual studies (p=0.10). Exact information on timing of infection and duration of breastfeeding was available for 20 of the 49 children with late postnatal transmission. We took transmission to have occurred midway between last negative and first positive HIV-1 tests. If breastfeeding had stopped at age 4 months transmission would have occurred in no infants, and in three if it had stopped at 6 months. INTERPRETATION: Risk of late postnatal transmission is consistently shown to be substantial for breastfed children born to HIV-1-positive mothers. This risk should be balanced against the effect of early weaning on infant mortality and morbidity and maternal fertility.

Unilateral pallidotomy in Parkinson's disease: a randomised, single-blind, multicentre trial.

BACKGROUND: The results of several cohort studies suggest that patients with advanced Parkinson's disease would benefit from unilateral pallidotomy. We have assessed the efficacy of unilateral pallidotomy in a randomised, single-blind, multicentre trial. METHODS: We enrolled 37 patients with advanced Parkinson's disease who had, despite optimum pharmacological treatment, at least one of the following symptoms: severe response fluctuations, dyskinesias, painful dystonias, or bradykinesia. Patients were randomly assigned to unilateral pallidotomy within 1 month or to pallidotomy after the primary outcome assessment (6 months later). The primary outcome was the difference between the groups in median changes on the motor examination section of the unified Parkinson's disease rating scale (UPDRS 3) score done in the off phase. Secondary outcome measures included levodopa-induced dyskinesias (dyskinesia rating scale [DRS]) and extent of disability (UPDRS 2). FINDINGS: The median UPDRS 3 off score of the pallidotomy patients improved from 47 to 32.5, whereas that of control patients slightly worsened from 52.5 to 56.5 (p<0.001). In the on phase the median DRS score improved 50% in pallidotomy patients compared with no change in controls. The UPDRS 2 off score improved with a median of 7 in the pallidotomy group. Two treated patients had major adverse effects. INTERPRETATION: Unilateral pallidotomy is an effective treatment in patients with advanced Parkinson's disease, who have an unsatisfactory response to pharmacological treatment.

[Skin diseases in the elderly: a multicentre Tunisian study].

INTRODUCTION: With progressive aging of populations, geriatric health care has become a major international issue for health authorities. However, little data is available about geriatric skin diseases. The aim of this study is to determine the pattern of skin disorders among elderly patients seen in private and public skin outpatient clinics in Tunis. PATIENTS AND METHODS: We performed a prospective, multicentre and descriptive study of all new skin diseases diagnosed in dermatological outpatients aged over 65 years. This study lasted one year (June 1999 to July 2000) and evaluated the activity of eleven Tunisian dermatologists in private or public practice, who collated all cases of skin diseases diagnosed in their practices. RESULTS: A total of 1518 patients with 1550 new diagnoses were examined. Mean age was 72.6 years with a sex M/F -ratio of 1.41. Fungal infections were the most common conditions (16.9%), followed by tumors 12.8% (benign 63.3%), eczema (11.9%), keratinization anomalies (8.7%), bacterial infections (8.7%), viral infections (6.8%) and pruritus (6.4%). Fungal infections were mainly represented by toe-web intertrigo and onychomycosis. Basal cell carcinoma and epidermoid cysts were the most common malignant and benign tumors respectively. DISCUSSION: This study reflects the frequency of mycoses, benign tumors and eczema in elderly patients. This is consistent with the results of other studies of the literature showing eczema as the predominant skin disease. The high prevalence of mycosis in our study may be explained by climatic conditions (heat, moisture). Pruritus seems to be frequent in geriatric patients. Skin disorders are an important source of morbidity in elderly patients.

Tuberculosis and AIDS: a retrospective, longitudinal, multicentre study of Italian AIDS patients. Italian group for the study of tuberculosis and AIDS (GISTA)

We report the results of a retrospective, longitudinal, multicentre study which estimated the cumulative incidence of tuberculosis in patients who eventually develop AIDS, investigated the characteristics of AIDS patients in relation to the development of tuberculosis, and endeavoured to determine the degree of HIV-induced immunosuppression at which tuberculosis occurs. The Infectious Disease Units of 23 hospitals located in 11 of the 20 regions of Italy participated in this study. We investigated 1691 patients with AIDS diagnosed in 1988 and 1989 and reported to the National AIDS Registry by participating units before the end of December 1990. By that time M. tuberculosis had been cultured from 193 patients (11.4%). Compared with intravenous drug users (the largest HIV transmission category), only homosexual men had a statistically significant lower risk of tuberculosis (relative risk = 0.65; 95% confidence interval 0.43-0.99). The median count of CD4+ lymphocytes at the time tuberculosis was diagnosed was 82/mm3 (range 1-752); only four patients (2.1%) had CD4+ lymphocyte counts of more than 500/mm3, and 36 (18.7%) of over 200/mm3. We conclude that in Italy the proportion of AIDS patients who develop tuberculosis is higher than in other industrialised countries and differences in the incidence of tuberculosis among various HIV-transmission categories are less marked than in other western countries. Tuberculosis associated with HIV infection may occur in those with widely differing CD4+ counts, although the risk increases consistently in proportion to the degree of immunosuppression.

Better efficacy of twice-monthly than monthly aerosolised pentamidine for secondary prophylaxis of Pneumocystis carinii pneumonia in patients with AIDS. An Italian multicentric randomised controlled trial. The Italian PCP Study Group.

The aim of this multicentric randomised controlled trial was to evaluate long-term efficacy and safety of once-monthly versus twice-monthly 300 mg aerosolized pentamidine (AP) as secondary prophylaxis of Pneumocystis carinii pneumonia (PCP). We randomised 205 patients with a previous confirmed episode of PCP (107 treated with 300 mg once-monthly AP, and 98 with 300 mg twice monthly AP); the median review period was 232 days. Kaplan-Meier method and Cox's hazard regression model were used for analysis. The main outcome assessments were PCP recurrence, survival and incidence of drug toxicity. The two groups were balanced for prognostic predictors. In the once-monthly AP group, 14 relapses of confirmed PCP were observed, while five occurred in the twice-monthly AP group; the crude relative risk (RR) was 2.69 (95% CI 1.002-7.236, P=0.0496) and the adjusted RR accounting for prognostic predictors was 2.62 (95% CI 0.92-7.5, P=0.071). Death occurred in 36 of 26 patients respectively (adjusted RR 1.32, 95% CI 0.8-2.18, P=0.28). Two patients interrupted the study because of intolerance to AP (one in each group), and severe coughing occurred in two patients (one in each group). At the end of the study, pulmonary function tests were not changed compared with baseline and were the same between the two groups. Our study suggests that 300 mg twice-monthly AP is more effective than 300 mg once-monthly AP as secondary prophylaxis of PCP.

Risperidone in the treatment of mania: efficacy and safety results from a large, multicentre, open study in Spain.

BACKGROUND: A number of open studies and preliminary results of unpublished double-blind trials have suggested that the novel antipsychotic risperidone may be effective and well tolerated in the treatment of acute mania in bipolar disorder. METHODS: A total of 174 patients entered this large, open, multicentre trial. Inclusion criteria were: current manic, hypomanic or mixed episode (DSM-IV), and a Young Mania Rating Scale (YMRS) score of >7. Assessments included the YMRS, Positive and Negative Syndrome Scale (PANSS), Hamilton Rating Scale for Depression (HAM-D), Clinical Global Impression (CGI), and Udvalg for Kliniske Undersøgelser (UKU) subscale for neurological side effects. RESULTS: There were significant reductions (P<0.0001) on the YMRS, PANSS and HAM-D scores and a significant improvement (P<0.0001) in CGI ratings at the endpoint. There were no statistically significant increments in the severity of extrapyramidal symptoms according to the UKU. Risperidone was generally well tolerated. The mean dose of risperidone at the endpoint was 4.9+/-2.9 mg/day. CONCLUSIONS AND CLINICAL IMPLICATIONS: This open study provides further evidence that risperidone is safe and effective in combination with mood stabilisers in the manic phase of bipolar disorder. LIMITATIONS: The open design and the use of concomitant medications make unclear to what extent the positive results were entirely related to risperidone.

Effects of comorbidity and polypharmacy on the clinical usefulness of sertraline in elderly depressed patients: an open multicentre study.

Antidepressant therapy in the elderly age group is frequently complicated by medical comorbidity, polypharmacy and increased sensitivity to drug effects. A nonblind, noncomparative, observational, multicentre study over 8 weeks was conducted to assess the effectiveness and tolerability of sertraline (50-200 mg/day) in 1437 elderly depressed outpatients with a mean (S.D.) age of 68 (6.3) years (range 60-92) in routine clinical practise. Depressive symptoms were monitored using the Montgomery Asberg Depression Rating Scale (MADRS) at baseline and at weeks 2, 4, 6 and 8. The mean dose of sertraline at the final visit was 85.2 mg/day (48% of patients were given the initial dose throughout the study). At the end of the study, mean percentage change of MADRS score from baseline was 61% (P < 0.001). A > or = 50% decrease in MADRS score was obtained in 70% of patients. Sertraline was well tolerated.
