Efficacy, safety and pharmacokinetic of once-daily boosted saquinavir (1500/100 mg) together with 2 nucleos(t)ide reverse transcriptase inhibitors in real life: a multicentre prospective study.

BACKGROUND. Ritonavir-boosted saquinavir (SQVr) is nowadays regarded as an alternative antiretroviral drug probably due to several drawbacks, such as its high pill burden, twice daily dosing and the requirement of 200 mg ritonavir when given at the current standard 1000/100 mg bid dosing. Several once-daily SQVr dosing schemes have been studied with the 200 mg SQV old formulations, trying to overcome some of these disadvantages. SQV 500 mg strength tablets became available at the end of 2005, thus facilitating a once-daily regimen with fewer pills, although there is very limited experience with this formulation yet. METHODS. Prospective, multicentre study in which efficacy, safety and pharmacokinetics of a regimen of once-daily SQVr 1500/100 mg plus 2 NRTIs were evaluated under routine clinical care conditions in either antiretroviral-naïve patients or in those with no previous history of antiretroviral treatments and/or genotypic resistance tests suggesting SQV resistance. Plasma SQV trough levels were measured by HPLV-UV. RESULTS. Five hundred and fourteen caucasian patients were included (47.2% coinfected with hepatitis C and/or B virus; 7.8% with cirrhosis). Efficacy at 52 weeks (plasma RNA-HIV <50 copies/ml) was 67.7% (CI95: 63.6 - 71.7%) by intention-to-treat, and 92.2% (CI95: 89.8 - 94.6%) by on-treatment analysis. The reasons for failure were: dropout or loss to follow-up (18.4%), virological failure (7.8%), adverse events (3.1%), and other reasons (4.6%). The high rate of dropout may be explained by an enrollment and follow-up under routine clinical care condition, and a population with a significant number of drug users. The median SQV Cmin (n = 49) was 295 ng/ml (range, 53-2172). The only variable associated with virological failure in the multivariate analysis was adherence (OR: 3.36; CI95, 1.51-7.46, p = 0.003). CONCLUSIONS. Our results suggests that SQVr (1500/100 mg) once-daily plus 2 NRTIs is an effective regimen, without severe clinical adverse events or hepatotoxicity, scarce lipid changes, and no interactions with methadone. All these factors and its once-daily administration suggest this regimen as an appropriate option in patients with no SQV resistance-associated mutations.

Compliance with dietary and nutrient recommendations in the European Prospective Investigation into Cancer and Nutrition (EPIC)-Granada cohort at recruitment

BACKGROUND: The overall intake of energy and nutrients in the Granada EPIC-cohort (European Prospective Investigation into Cancer and Nutrition) is examined in order to assess compliance with the Spanish Nutritional Objectives (NO) and the Recommended Intakes (RI). METHODS: During recruitment (1992-1996), 7,789 participants, aged 35-69, were asked about diet through a validated diet history questionnaire. Nutrient intake is compared to the NO and RI that were valid at that time. Risk of inadequate intake is estimated as the percentage of the sample with intakes: ≤ 1/3 RI (high risk), ≤ 2/3 RI- > 1/3 RI (moderate risk), ≤ RI- > 2/3 RI, > RI. Differences in intakes have been analyzed by sex and age, and by smoking status and BMI. RESULTS: The daily intake of nutrients did not meet the NO as the total contribution of energy from proteins and fats exceeded these guidelines. Whilst intake of most nutrients was above the RI, the amount of iron, magnesium and vitamins D and E provided by the diet was not enough to meet the RI: in women aged 20-49 years, about 55% were at moderate risk for iron inadequacy, and a 20% of women for magnesium. Both sexes were at high risk of inadequacy for vitamin D, although sunlight exposure may supply adequate amounts. Never smokers showed a higher compliance to the NO. CONCLUSION: At recruitment, the nutrient profile of the diet was unbalanced. The observed nutrient inadequacy for iron, magnesium and vitamin E might be attributed to inappropriate dietary habits, and may have implications for future disease risk.

Chronology of extraintestinal manifestations relative to IBD diagnosis in the Swiss IBD Cohort

Background and Aims: Due to a p aucity of s uch data we aimed to a ssess the type and f requency o f extraintestinal manifestations ( EIM) in I BD p atients and to e valuate their chronologic behavior. Methods: A nalysis of d ata from t he Swiss Inflammatory Bowel Disease Cohort (SIBDCS) which c ollects data since 2 005 on a large sample o f IBD patients f rom hospitals and private practices across Switzerland. Results: A t total o f 1,143 patients were a nalyzed ( 572 (50%) female, mean age 42.1 ± 14.4 years), 629 with Crohn's disease (CD), 501 with ulcerative colitis (UC), and 13 with indeterminate colitis ( IC). Of t hese, 3 74 (32.7%) presented o ne to five E IM (65% w ith CD, 3 3% w ith UC, 2% w ith IC). O f those patients suffering from EIM, 4 1.7% p resented two, 1 2.4% t hree, 5 .3% four, and 3.2% f ive E IM d uring lifetime. T he initial EIM presented with the following frequencies: p eripheral a rthritis (PA) 6 3.4%, ankylosing spondylitis (AS) 8 .1%, primary sclerosing cholangitis (PSC) 6%, uveitis 5.7%, oral a phthosis 5.7%, erythema nodosum (EN) 5 %, other 3 .6%, pyoderma gangrenosum 1.8%, psoriasis 0.7%. In only 7.1% of cases, the EIM m anifested before IBD diagnosis was made (median time 28 months b efore IBD diagnosis, I QR 7 -60 months), in 9 2.9% EIM m anifested a fter e stablished IBD d iagnosis (median 72 months, IQR 9-147 months). Conclusions: EIM are a frequent problem in IBD patients. The vast m ajority of E IM m anifest a fter I BD d iagnosis has b een established. P eripheral a rthritis, a nkylosing spondylitis, a nd PSC represent the most frequent first manifestations of an EIM.
