Modified cued recall test in the French population with Down syndrome: A retrospective medical records analysis.

BACKGROUND: Adults with Down syndrome (DS) are at increased risk of developing Alzheimer's disease (AD) due to genetic predisposition. Identification of patients with AD is difficult since intellectual disabilities (ID) may confound diagnosis. The objective of this study was to evaluate the ability of the French version of the modified cued recall test (mCRT) to distinguish between subjects with and without AD in the adult DS population. METHODS: This was a retrospective, single-centre, medical records study including data between March 2014 and July 2020. Adults aged ≥30 years with DS who had at least one mCRT record available were eligible. Age, sex and ID level were extracted, and subjects were attributed to three groups: patients with AD, patients with co-occurring conditions that may impact cognitive function and subjects without AD. mCRT scores, adjusted by sex, age and ID level, were compared between groups. The optimal cut-off value to distinguish between patients with and without AD was determined using the receiver operating characteristic curve. The impact of age and ID level on mCRT scores was assessed. RESULTS: Overall, 194 patients with DS were included: 12 patients with AD, 94 patients with co-occurring conditions and 88 healthy subjects. Total recall scores were significantly lower (P < 0.0001) in patients with AD compared with healthy subjects. The optimal cut-off value to discriminate between patients with AD and healthy subjects was 22, which compares well with the cut-off value of 23 originally reported for the English version of the mCRT. Patients aged 30-44 years had higher mCRT total recall scores compared with patients aged ≥45 years (P = 0.0221). Similarly, patients with mild ID had higher mCRT scores compared with patients with severe ID (P < 0.0001). INTERPRETATION: The mCRT is a sensitive tool that may help in the clinical diagnosis of AD in subjects with DS. Early recognition of AD is paramount to deliver appropriate interventions to this vulnerable population.

[Asthma control in adult Algerian patients. Comparison with other North African and Middle-East countries]. / Contrôle de l'asthme chez l'adulte en Algérie. Comparaison avec les autres pays d'Afrique du Nord et du Moyen Orient.

INTRODUCTION: Lack of recent data on asthma control in Algeria led to this study whose results were compared with those of the same study conducted in the Middle East and North Africa (MENA). METHOD: This cross-sectional epidemiological study was performed in adults who had been diagnosed with asthma for at least one year and without exacerbation within the last 4 weeks. Asthma control was assessed using the 2012 Global Initiative for Asthma (GINA) criteria and the Asthma control test (ACT) questionnaire. RESULTS: We studied 984 patients mainly managed by specialist physicians; 61% female, mean age 45 years, body mass index 27kg/m2, active smokers 2%. Medication was prescribed in 92% with 78% receiving inhaled corticosteroids alone or with add-on therapies. Good adherence was observed in 27%. Asthma control was observed in 34.6% vs. 28.6% in other countries (P < 0.001). Low level of education, absence of medical insurance, lack of physical exercise, and-long duration of the disease were significantly associated with uncontrolled asthma. CONCLUSION: Poor control of asthma is still observed in Algeria despite a high level of specialist involvement. Except for adherence, known predictive factors of poor asthma control have been observed. Quality improvement training of health care professionals and patient education are probably the main issues to be addressed.

A trial comparing local pain after subcutaneous injection of epoetin-beta versus darbepoetin-alpha in healthy volunteers.

BACKGROUND: The aim of this study was to compare local pain experienced with subcutaneous (s.c.) injection of epoetin-beta vs. darbepoetin-alpha. METHODS: 40 healthy volunteers were enrolled into this single-blind, crossover study. After receiving an injection of placebo, individuals were randomized to receive s.c. injections of epoetin-beta 6,000 IU (0.3 ml) or darbepoetin-alpha 30 mg (0.3 ml), with a 1-week washout period between injections. Local pain was evaluated using a Visual Analog Scale (VAS) and a 6-item Verbal Rating Scale (VRS) immediately after (T0) and 1 h after injection (T1). RESULTS: The respective mean (standard deviation) and median (range) VAS values at T0 were 1.2 (1.7) and 0.5 (0.0 - 6.9) for epoetin-beta vs. 2.8 (2.4) and 1.9 (0.0 - 9.0) for darbepoetin-alpha (p < 0.0001). At T0, VRS scores demonstrated that 51% of individuals experienced no pain after epoetin- injection compared with 16% of those receiving darbepoetin-alpha. The percentage of individuals perceiving moderate or important pain was significantly greater with darbepoetin-alpha (38%) compared with epoetin-beta (5%, p = 0.0005) and placebo (14%). Pain evaluation at T1 showed no difference between treatment groups. Local tolerance was excellent except for a small hematoma with epoetin- at T1 and with darbepoetin-alpha at T0 which persisted at T1. CONCLUSION: In healthy volunteers, s.c. injection of epoetin-beta was significantly less painful than with darbepoetin-alpha and comparable with placebo. No significant pain was apparent at T1 in any group.

Multicentre, phase II study evaluating capecitabine monotherapy in patients with anthracycline- and taxane-pretreated metastatic breast cancer.

Treating patients with anthracycline- and taxane-pretreated metastatic breast cancer (MBC) represents a significant challenge to oncologists. The tumour-activated oral fluoropyrimidine, capecitabine, is the only treatment approved for these patients. Our study evaluated the efficacy, safety and impact on quality of life (QOL) of capecitabine in this setting. Patients (n=126) with anthracycline- and taxane-pretreated metastatic breast cancer received capecitabine 1250 mg/m(2) twice daily, days 1-14, followed by a 7-day rest period. Median time to progression was 4.9 months (95% Confidence Interval (CI): 4.0-6.4). Thirty-five patients (28%) achieved an objective response (95% CI: 20-36%), including five (4%) complete responses. Median overall survival was 15.2 months (95% CI: 13.5-19.6 months). Capecitabine demonstrated a favourable safety profile, with a low incidence of treatment-related grade 3/4 adverse events. The most common adverse events were hand-foot syndrome and gastrointestinal effects. QOL assessment showed that capecitabine treatment was associated with an increase in mean Global Health Score. Capecitabine is active, well tolerated and improves the QOL of patients with anthracycline- and taxane-pretreated metastatic breast cancer. Based on the consistently high activity demonstrated in clinical trials, capecitabine has become the reference treatment in this setting.

Absolute bioavailability of midazolam after subcutaneous administration to healthy volunteers.

AIMS: Midazolam is given intravenously for induction of anaesthesia and conscious sedation and by subcutaneous infusion in patients in palliative care units. The objective of the present study was to determine the absolute bioavailability of subcutaneous midazolam and its pharmacokinetics in young, healthy, male volunteers. METHODS: Eighteen volunteers were given single doses of 0.1 mg kg-1 midazolam i.v. and s.c. after a wash-out period of 7-15 days in an open-label, randomized, cross-over study. Blood samples were collected up to 12 h post-infusion. Plasma concentrations of midazolam and of its two metabolites, 1'-OHM and 4-OHM, were assessed using an h.p.l.c.-MS method (LOQ 0.5 ng ml-1 for each analyte). Vital signs, cardiac parameters and oximetry were monitored. Local tolerance was determined and adverse events were also monitored. RESULTS: After s.c. infusion t(max) and C(max) were 0.51 +/- 0.18 h and 127.8 +/- 29.3 ng ml-1 (mean +/- s.d.), respectively. No statistically significant difference was detected in AUC(0, infinity ) after i.v. and s.c. administration. The mean (+/- s.d.) absolute bioavailability of subcutaneous midazolam was 0.96 (+/- 0.14) (CI 0.84, 1.03). Mean (+/- s.d.) t1/2 was similar after s.c. (3.2 (+/- 1.0) h) and i.v. infusion (2.9 (+/- 0.7) h), although a statistically significant difference was reached (P < 0.05). Mean CL and V of i.v. midazolam were 4.4 +/- 1.0 ml min-1 kg-1 and 1.1 +/- 0.2 l kg-1 (mean +/- s.d.), respectively. Plasma concentrations of 1'-OHM were higher than those of 4-OHM. Few mild and transient adverse events were noted and there were no clinically significant effects on EEG, blood pressure and laboratory parameters. CONCLUSIONS: This study has shown that subcutaneous midazolam has excellent bioavailability and that administration of midazolam by this route could be preferable when the intravenous route is inappropriate.

MIKADO: a multicentre, open-label pilot study to evaluate the antiretroviral activity and safety of saquinavir with stavudine and zalcitabine.

BACKGROUND: Since eradication of HIV is unlikely, long-term management of the disease necessitates careful evaluation of the combinations of currently available drugs to determine the most potent and useful rational sequencing of regimens. OBJECTIVE: To determine the antiretroviral efficacy and tolerability of saquinavir soft gelatin capsule (SQV-SGC) plus zalcitabine (ddC) and stavudine (d4T), as first-line treatment in HIV-infected patients. DESIGN: Multicentre, open-label, non-comparative study. PATIENTS AND METHODS: Thirty-five asymptomatic, HIV-infected adults with no prior antiretroviral treatment, a CD4 count > or =250 cells/microL and baseline > or = 5000 HIV RNA copies/mL were included in the study. Patients received SQV-SGC 1200 mg three times a day (tid), ddC 0.75 mg tid and d4T 30 or 40 mg twice a day (bid) for 24 weeks. Plasma HIV RNA, CD4 and CD8 cell counts, HIV reverse transcriptase and protease resistance genotypes, SQV plasma concentration and tolerability were evaluated. RESULTS: At baseline, median HIV RNA (interquartile range) was 4.99 (4.81-5.48) log10 copies/mL, and median CD4 count was 370 (318-504) cells/microL (n = 35). At week 24, the median decrease in HIV RNA was 3.05 (2.19-3.68) log10 copies/mL. A viral load below the level of quantification (200 copies/mL and 20 copies/mL) was achieved in 63% and 34% of patients, respectively (intent-to-treat analysis). The only mutations detected were L90M substitutions in two patients. At week 24, the median CD4 count increased (P < 0.0001), and CD8 cell counts decreased (P < 0.0001), relative to baseline. In total, there were five cases of peripheral neuropathy (14%). Mean triglyceride and cholesterol levels remained within normal ranges. CONCLUSIONS: Triple therapy with SQV-SGC plus ddC and d4T is a reasonably well tolerated regimen that markedly and rapidly reduces viral load with immunological improvement. This combination is an effective additional therapeutic option, with an efficacy that compares favourably to other triple regimens used in HIV treatment.

Rituximab (anti-CD20 monoclonal antibody) as single first-line therapy for patients with follicular lymphoma with a low tumor burden: clinical and molecular evaluation.

The clinical activity of rituximab, a chimeric monoclonal antibody which binds to the CD20 antigen, was evaluated as a single first-line therapy for patients with follicular non-Hodgkin lymphoma (NHL). Fifty patients with follicular CD20(+) NHL and a low tumor burden were analyzed for clinical and molecular responses. They received 4 weekly infusions of rituximab at a dose of 375 mg/m(2). The response rate a month after treatment (day 50) was 36 of 49 (73%), with 10 patients in complete remission, 3 patients in complete remission/unconfirmed, and 23 patients in partial remission. Ten patients had stable disease, and the disease progressed in 3 patients. One of 13 (8%) patients in complete remission, 9 of 23 (39%) patients in partial remission, and 5 of 10 (50%) patients with stable disease exhibited disease progression during the first year. Within the study population, 32 patients were initially informative for polymerase chain reaction (PCR) data on bcl-2-J(H) rearrangement. On day 50, 17 of 30 patients (57%) were negative for bcl-2-J(H) rearrangement in peripheral blood, and 9 of 29 (31%) were negative in bone marrow; a significant association was observed between molecular and clinical responses (P <.0001). At month 12, 16 of 26 patients (62%) were PCR negative in peripheral blood. These results indicate that early molecular responses can be sustained for up to 12 months and that this response is highly correlated with progression-free survival. Rituximab has a high clinical activity and a low toxicity and induces a high complete molecular response rate in patients with follicular lymphoma and a low tumor burden.

Calcium antagonists and thiazide diuretics have opposite effects on blood rheology and radial artery compliance in arterial hypertension: a randomized double-blind study.

In addition to their effects on blood pressure, antihypertensive agents may produce additional effects on blood rheology and arterial compliance abnormalities which may play a role in target-organ damage. However, these effects may depend only on the specific pharmacological properties of certain antihypertensive agents, and may be partly unrelated to blood pressure lowering action. We compared the effects of nitrendipine 20 mg once daily to hydrochlorothiazide 25 mg once daily in 33 mildly to moderately hypertensive and otherwise healthy patients, in a double blind parallel group trial. Blood rheology (blood fibrinogen and protein concentrations, hematocrit, plasma viscosity and whole blood viscosity at shear rates 0.2 to 128 s-1, erythrocyte deformability and aggregation) and radial artery diameter and compliance (Nius I + Finapres) were measured at baseline and after 2 months of treatment. Both drugs produced similar blood pressure lowering. Blood viscosity increased for all shear rates in the hydrochlorothiazide group and decreased in the nitrendipine treated group. Erythrocyte deformability increased in the nitrendipine but not in the thiazide group. Radial artery diameter and compliance were not different between the two groups but there was a trend towards an increase in cross-sectional compliance in the hydrochlorothiazide group and towards a decrease in the nitrendipine group. Our data show that, in mildly hypertensive patients, blood pressure control by nitrendipine produced more favourable effects on relevant rheological variables than hydrochlorothiazide. Radial artery compliance changes tended to be altered also in opposite directions by the two agents. The significance and the clinical relevance of these effects may require further investigations.

[Double-blind randomized comparative study of nicergoline naftidrofuryl on the quality of life in chronic obliterative arteriopathy of lower limbs with intermittent claudication]. / Etude comparative randomisée en double-aveugle de la nicergoline et du naftidrofuryl sur la qualité de vie dans l'artériopathie chronique oblitérante des membres inférieurs au stade de la claudication intermittente.

The functional limitation of patients with obliterative arterial disease, and with intermittent claudication, damages their quality of life. The purpose of this trial was to compare the effects of nicergoline and naftidrofuryl on the quality of life and the functional discomfort of the 131 patients with claudication. It was a multicentre, randomised, double-blind trial with parallel groups. The patients were asked to complete a quality of life questionnaire and a Visual Analogue Scale, and to evaluate the number of steps on flat ground before the pain began. After 6 months of treatment, we observed, for all treatments combined, a significant improvement (p = 0.0001) in the quality of life and in the functional discomfort. Three variables favoured nicergoline: the estimated time before the onset of the pain (p = 0.003), the functional discomfort quantified by the Visual Analogue Scale (p < 0.05), the distance covered on flat ground (p = 0.013). The other variables, and especially the total score on the self-questionnaire, confirmed this impression, without reaching significance (p = 0.136). The data suggest that in terms of quality of life nicergoline is superior. The clinical tolerance is good and comparable between the two treatments.

[Efficacy and tolerability of pristinamycin vs amoxicillin-clavulanic acid combination in the treatment of acute community-acquired pneumonia in hospitalized adults]. / Efficacité et tolérance de la pristinamycin vs l'association amoxicilline-acide clavulanique dans le traitement des pneumopathies aiguës communautaires de l'adulte hospitalisé.

The aim of this double-blind, 2 parallel group, randomized, multicenter study was to compare the efficacy and the safety of pristinamycin (P), 1 g bid, versus amoxicillin-clavulanic acid (AAC), 500 mg q.i.d., for 10-14 days in the treatment of non severe community-acquired pneumonia in hospitalized adults. From December 1992 to July 1994, 180 patients were included: 92 in the group P and 88 in the group AAC. The both groups were similar on demographic, clinical and bacteriological criteria. 96 pathogens of which more than half were pneumococci, were isolated in 79/180 (44%) patients. The primary assessment was the global success rate defined as long-term (D40 +/- 7), clinical, radiological and bacteriological efficacy in the "per protocol" population (75 patients in the group P and 83 in the group AAC). The global success was obtained in 63/75 (84%) patients in the group P and 70/83 (84.3%) patients in the group AAC. At the end of treatment (D14 +/- 3), theses rates were respectively 85.4% and 84.3%. The both treatments were equivalents. Adverse events (mainly gastro-intestinal disorders) were reported by 55/92 (59.8%) patients in the group P and 49/87 (56.2%) patients in the group AAC.
