Abstract Studies establishing that intermittent subcutaneous interleukin-2 (IL-2) therapy can lead to substantial CD4 cell increases in many HIV-infected patients have generally been of limited duration. We studied 77 patients participating in active longitudinal studies of subcutaneous IL-2 therapy at our center in order to determine the long-term feasibility of this approach. Following initial induction, patients in each trial were eligible to receive intermittent 5-day cycles of subcutaneous IL-2 treatment at individualized doses and frequencies capable of maintaining CD4 counts at postinduction levels. The mean duration of study participation to date is 5.9 years (range, 1.0-9.3 years). Mean baseline CD4 cell count and CD4 percent values of 0.521 × 109/L (521 cells/μL) and 27% have risen to 1.005 × 109/L (1005 cells/μL) and 38%, respectively, at 90 months. The mean number of subcutaneous IL-2 cycles required to achieve and maintain these increases was 10 cycles (range, 3-29 cycles), and the current mean interval of cycling required to maintain these elevations is 39 months (median, 35 months; range, 2-91 months). We conclude that subcutaneous IL-2 therapy is capable of maintaining CD4 cell increases for an extended period using a remarkably low frequency of intermittent cycling. These observations may contribute to patients' acceptance of subcutaneous IL-2 as a favorable long-term treatment strategy. (Blood. 2004;103:3282-3286)

The effect of long-term treatment with sodium nedocromil on airway hypereactivity was investigated in two groups of 20 patients each. Group I patients presented with allergic asthma while Group II patients presented with intrinsic asthma. For each subject of the two groups, the base FEV1 was measured and nebulized methacholine was administrated in consecutively higher concentrations until a decrease in FEV1 of >20 % was observed. Following measurement, all patients included in the study were treated with 12 mg of sodium nedocromil per day for 12 months. At the end of the treatment, bronchial hyperreactivity was evaluated for a second time by administering the same dosage of methacholine that originally produced a decline in FEV1 of >20 %. In Group I patients (allergic asthma) mean FEV1 was 3126 ml, before challenge, while after methacholine challenge FEV1 was 2400ml. Following 1-year of sodium nedocromil administration the FEV1 was 2601ml (P<0.05). Before treatment, the mean fall in FEV1, following methacholine challenge, was 23.67% while following a 1-year-long sodium nedocromil administration this value reduced to 15.70% (P<0.05). Correspondingly, PC20 was 5.59 while after sodium nedocromil administration it increased to 11.66 (P<0.05). In Group II patients (intrinsic asthma) mean FEV1 was 2750 ml, before challenge, while after methacholine challenge FEV1 was 2066ml. Following 1-year of sodium nedocromil administration the FEV1 was 2223ml (P<0.05). Before treatment, the mean fall in FEV1, following methacholine challenge, was 27.65 % while following a 1-year-long sodium nedocromil administration this value reduced to 21.92 % (P<0.05). Correspondingly, PC20 was 5.91 while after sodium nedocromil administration it increased to 6.19 (P<0.05). The results suggest a positive effect of long-term sodium nedocromil administration in bronchial hyperreactivity for both groups of patients.

306 Background: Pharmacokinetic study in patients with gastrointestinal stromal tumors (GISTs) suggested that plasma concentrations of imatinib decrease following long-term exposure. We therefore measured changes in imatinib plasma trough levels (Cmin) after long-term exposure. Methods: Between November 2009 and May 2010, follow-up (FU) imatinib Cmin was measured in 65 patients who received the same dose of imatinib for at least 9 months after a previous baseline (BL) measurement. Total 244 blood samples were obtained (127 at BL and 117 at FU) and plasma level was measured by liquid chromatography-tandem mass spectrometry. Results: Median patient age was 54 years (range, 28–76 years) and 42 (64.6%) patients were male. Sixty-one (93.8%) patients were treated with 400 mg/day imatinib and 4 (6.2%) with 300 mg/day. The median interval from initiation of imatinib to BL test was 6.4 months (range, 0.5–66.6 months), and the median interval between BL and FU test was 13.1 months (range, 9.6–18.4 months). The mean ± standard deviation imatinib Cmin was significantly higher at FU than at BL (1442 ± 693 ng/mL vs 1221 ± 624 ng/mL, p<0.001). The mean inter- and intra-subject variabilities were 49.2% and 25.5%, respectively, at BL, and 44.2% and 20.4%, respectively, at FU. Multivariate analysis showed a significant correlation between the ratio of FU to BL imatinib Cmin and that of albumin (r=-0.397, p=0.001). In per-sample analysis, imatinib Cmin was significantly correlated with age, hemoglobin, albumin, creatinine clearance, previous major gastrectomy and time between initiation of imatinib and plasma level tests. Conclusions: Steady-state imatinib Cmin did not decrease but remained stable in most GIST patients during long-term treatment. Changes in imatinib Cmin were associated with changes in albumin concentration. Monitoring of imatinib Cmin only for concerns about time-dependent decreases in imatinib exposure is not necessary.

AbstractThe effect of long-term treatment of goats with methylthiouracil on the timing, amount and quality of secondary fibre (cashmere) growth and timing of cashmere moult in goats was investigated. From early June, groups of 10 Icelandic × Scottish feral goats were dosed orally each day, for a 15-month period, with 5 mg methylthiouracil per kg live weight in 30 ml water (treated; T) or with water only (control; C). Treatment with methylthiouracil resulted in a significant reduction (P < 0·05) in the proportion of active secondary hair follicles present during March. This was associated with a delayed onset of moult of cashmere in T compared with C goats at both the head (11 March v. 23 February; s.e. 3·33 days; P< 0·05) and mid side (27 March v. 26 February; s.e. 3·58 days; P < 0·001). There was no effect on the time of onset (C, 19 July; T, 19 July; s.e. 5·84 days) or cessation of cashmere fibre growth (C, 9 December; T, 8 December; s.e. 1·69 days) or the mean growth rate (C, 0·473 mm/day; T, 0·451 mm/day; s.e. 0·025) and fibre diameter (C, 16·9 μm; T, 15·4 jim; s.e. 0·266). Wlien present in the fleece, the mean weight and proportion of cashmere was higher in C than in T goats (P < 0·05). It is concluded that methylthiouracil treatment altered secondary follicle activity and the time of onset of the moult of cashmere and that these changes may be a result of reduced triiodothyronine production from thyroxine and associated secondary changes in profiles of insulin and IGF-1.

Background: Preliminary studies showed anti HBV nucleoside analogues treatment might improve the histopathology and improve the survival of the cirrhotic patients. Data about efficacy of anti-HBV treatment in Vietnamese cirrhotic patients was still very limited. This study was aimed at assessing the biochemical, virological and the fibrosis responses to Tenofovir disoproxil fumarate (Tenofovir DF) in patients with HBVrelated compensated cirrhosis. Patients and methods: 48 patients of HBV-related compensated cirrhosis, diagnosed by Acoustic radiation Forced Imaging (ARFI), were enrolled. Tenofovir DF was given at dose of 300 mg per day, followed in 24 months. Results: ALT normalization and HBV DNA responses were found in 91.7% and 87.5%, respectively, of all patients. The mean of SWV was significantly improved after 24 months, from 2.16 ± 0.28 m/s down to 1.80± 0.22 m/s after 24 months of tenofovir treatment. Especially, 15 patients (31.2%) have obtained a remarkable improvement of fibrosis from F4 down to F3 or even F2. Conclusion: Tenofovir treatment in patients with HBV- related compensated cirrhosis may provide not only biochemical and virological responses but also improves in liver fibrosis, especially after long-term treatment.

ObjectiveThis study investigated the safety and efficacy of long-term treatment with high-dose desvenlafaxine (administered as desvenlafaxine succinate) in major depressive disorder (MDD).MethodsIn this multicenter, open-label study, adult outpatients with MDD aged 18–75 were treated with flexible doses of desvenlafaxine (200–400 mg/d) for ≤ 1 year. Safety assessments included monitoring of treatment-emergent adverse events (TEAEs), patient discontinuations due to adverse events, electrocardiograms, vital signs, and laboratory determinations. The primary efficacy measure was mean change from baseline in the 17-item Hamilton Rating Scale for Depression [HAM-D(17)] total score.ResultsThe mean daily desvenlafaxine dose range over the duration of the trial was 267–356 mg (after titration). The most frequent TEAEs in the safety population (n = 104) were nausea (52%) and headache (41%), dizziness (31%), insomnia (29%), and dry mouth (27%). All TEAEs were mild or moderate in severity. Thirty-four (33%) patients discontinued from the study because of TEAEs; nausea (12%) and dizziness (9%) were the most frequently cited reasons. The mean change in HAM-D(17) total score for the intent-to-treat population (n = 99) was −9.9 at the last on-therapy visit in the last-observation-carried-forward analysis and −14.0 at month 12 in the observed cases analysis.ConclusionHigh-dose desvenlafaxine (200–400 mg/d) was generally safe and effective in the long-term treatment of MDD.

PurposeTo report the long-term anatomical and visual outcomes of intravitreal bevacizumab (IVB) monotherapy in naive choroidal neovascularisation (CNV) caused by myopia.MethodsRetrospective analysis of naive CNV secondary to myopia that underwent antivascular endothelial growth factor monotherapy was performed. Collected data included demographic details, clinical examination details including visual acuity at presentation and follow-up with imaging and treatment details. Main outcome measures were resolution of CNV activity at the last visit. Secondary outcomes included change in visual acuity, number of injections and adverse events.ResultsThirty-three eyes of 31 subjects with a mean age of 51.48±16.4 years were included. The mean follow-up was 66.47 months. 27 eyes had type 2 CNV and the rest seven eyes had type 1 CNV. The mean number of IVB injections per eye was 4.9. Mean visual acuity at baseline reduced from 0.65±0.33 logMAR units (Snellen equivalent=20/89) to 0.73±0.50 logMAR units (20/107) at final follow-up (p=0.003). The mean central macular thickness decreased from 309.31±86 µm at baseline to 267.5±70.89 µm at the last visit (p=0.03). However, visual acuity was maintained (±1 line of baseline) in 13 eyes (39.4%), ≥2 line improvement in nine (27.3%) eyes and more than two lines worsening in 11 eyes (33.3%). Foveal atrophy was observed at baseline and last visit in 6 (12.5%) and 14 (29.1%), respectively (p=0.007). No systemic adverse events were observed.ConclusionIVB monotherapy is safe and effective for long-term treatment of CNV secondary to myopia in real life.
