[Title]: [Side-effects of triamcinolone in young patients].
[Abstract]: CASE REPORTS: Intravitreal triamcinolone is being increasingly employed for the treatment of macular diseases. We report two cases of intraocular pressure elevation and cataract formation after intravitreal triamcinolone therapy, and wonder if these complications are more likely when this agent is used in young patients. Intravitreal triamcinolone was injected into both eyes of the two young patients with chronic posterior and intermediate uveitis refractory to peribulbar and oral corticosteroid therapy. Chronic cystoid macular edema improved in both patients, however the intraocular pressure increased, requiring topical antihypertensive therapy, and this was followed by accelerated cataract formation. DISCUSSION: Young age and chronic inflammation could be associated with an intraocular pressure rise and subsequent cataract development after intravitreal triamcinolone.

[Title]: Effect of fenofibrate in combination with urate lowering agents in patients with gout.
[Abstract]: BACKGROUND: To assess the efficacy of fenofibrate treatment in combination with urate lowering agents in patients with gout. METHODS: Fourteen male patients with chronic tophaceous or recurrent acute attacks of gout were evaluated in an open-label pilot study of the hypolipidemic agent, fenofibrate (Lipidil Supra 160 mg/d). Patients were stable on urate lowering agents (allopurinol or benzbromarone) for > or = three months without acute attack for the most recent one month before participating. All patients were being treated with established doses of urate lowering agents without modification throughout the study. Clinical and biochemical assessments including serum uric acid, creatinine, liver function test and fasting serum lipid were measured at (1) baseline (2) after two months of fenofibrate treatment and (3) two months after fenofibrate was withdrawn. RESULTS: Serum uric acid was lowered by 23% after two months of fenofibrate treatment (6.93 +/- 2.16 vs. 5.22 +/- 1.16 mg/dL; p = 0.016). Triglyceride levels were also reduced after fenofibrate treatment (p = 0.001). However, this effect was reversed after the withdrawal (p = 0.002) of the drug. Alkaline phosphatase was reduced after fenofibrate treatment (p = 0.006), but increased 21% after the withdrawal of the drug (p = 0.002). By contrast, serum levels of high density lipoprotein and creatinine were increased 9% (p = 0.018) and 12% (p = 0.006), respectively; however, both levels were significantly decreased to the baseline levels upon withdrawal of fenofibrate. CONCLUSIONS: Fenofibrate can effectively reduce uric acid levels in addition to its known hypolipidemic effect. Fenofibrate may be used as a potential urate lowering agent in patients with gout, especially in those with coexisting hyperlipidemia.

[Title]: Multicenter study with isradipine and diuretics against atherosclerosis. US MIDAS Research Group.
[Abstract]: Hypertension is a major risk factor for atherosclerosis. Although antihypertensive drug treatment can reduce morbidity and mortality from stroke, there is no consistent benefit on ischemic heart disease. It may be that subtle adverse effects of the drugs used in these clinical trials may have blunted the beneficial effects of treatment. Isradipine, a new calcium antagonist of the dihydropyridine class, is a potent antihypertensive drug with pronounced antiatherogenic properties, at least in animal studies. Thus, isradipine may be a suitable drug for assessing the efficacy of antihypertensive treatment in retarding the progression of atherosclerosis. The Multicenter Isradipine/Diuretic Atherosclerosis Study (MIDAS) is a clinical trial to compare the efficacy of isradipine (2.5-5.0 mg b.i.d.) and hydrochlorothiazide (12.5-25 mg b.i.d.) in retarding atherosclerosis in carotid arteries. Carotid atherosclerosis will be monitored using B-mode ultrasonography. The sample size is 800 men and women aged 40 years and over. The power of the design is 90% to detect a 30% difference in the progression of plaque size between the isradipine- and hydrochlorothiazide-treated groups with a significance level of 5% (p = 0.05).

[Title]: Synergy between mannose-binding lectin gene polymorphisms and supplementation with vitamin A influences susceptibility to HIV infection in infants born to HIV-positive mothers.
[Abstract]: BACKGROUND: Mannose-binding lectin (MBL-2) allele variants are associated with deficiencies in innate immunity and have been found to be correlated with HIV infection in adults and children. OBJECTIVE: We tested whether MBL-2 variants among infants born to HIV-positive mothers have an increased susceptibility to HIV. DESIGN: MBL-2 allele variants were measured among 225 infants born to HIV-positive mothers enrolled in a trial in Durban, South Africa. Mothers of 108 infants were randomly assigned to receive vitamin A and beta-carotene supplementation and 117 to receive placebo. Infants were followed with regular HIV tests to determine rates of mother-to-child HIV transmission. RESULTS: A high proportion of infants were either homozygous (10.7%) or heterozygous (32.4%) for MBL-2 variants. MBL-2 variants within the placebo arm were associated with an increased risk of HIV transmission (odds ratio: 3.09; 95% CI: 1.21, 7.86); however, MBL-2 variants within the supplementation arm were not associated with an increased risk of transmission (P = 0.04; test of interaction). Among infants with MBL-2 variants, supplementation was associated with a decreased risk of HIV transmission (odds ratio: 0.37; 95% CI: 0.15, 0.91). CONCLUSION: We observed what appears to be a gene-environment interaction between MBL-2 variants and an intervention with vitamin A plus beta-carotene that is relevant to mother-to-child HIV transmission.

[Title]: Trastuzumab in combination with metronomic cyclophosphamide and methotrexate in patients with HER-2 positive metastatic breast cancer.
[Abstract]: BACKGROUND: HER2/neu overexpression is linked to promotion of angiogenesis in breast cancer. We therefore tested the activity of the combination of Trastuzumab with metronomic, low dose chemotherapy with cyclophosphamide (CTX) and methotrexate (MTX) in metastatic breast cancer (MBC). METHODS: Between April 2002 and June 2005, twenty-two patients with metastatic breast cancer with the presence of overexpression or amplification of HER2-/neu, all pre-treated with trastuzumab plus other cytotoxics, were treated with trastuzumab (6 mg/kg every three weeks) in combination with metronomic chemotherapy (MTX 2.5 mg, bid on Day 1 and Day 4 every week) and CTX (50 mg daily) (CM). RESULTS: The 22 enrolled patients are evaluable: most had an ECOG performance status of 0 (17 pts), and all were pre-treated with chemotherapy for metastatic disease; 14 had progressive disease at study entry, and 11 had progressive disease during the last trastuzumab therapy. Metastatic sites included: lung (5 pts), liver (14 pts), bone (12 pts), lymph nodes (8 pts), central nervous system (CNS) (9 pts). We observed 4 partial remission (PR) (18%, 95% CI 5-40%), 10 stable disease (SD) (46%, 95% CI 24-68%), and 8 PD (36%, CI 17-59%). The clinical benefit (RP plus RC plus SD for &gt; or = 24 weeks) in all pts and in pts with disease resistant to previous trastuzumab therapy were 46% (95% CI, 24-68%) and 27% (95% CI, 6-61%), respectively. Median time to progression was 6 months and median duration of treatment was 5 months (range, 0,7 to 18.4 months and range, 1 to 18 months, respectively). Overall clinical toxicity was generally mild. Grade &gt; or =2 reversible liver toxicity and leukopenia were reported in 5 and 3 pts, respectively. CONCLUSION: The combination of trastuzumab and metronomic chemotherapy is effective and minimally toxic in advanced breast cancer patients. The efficacy observed in patients with disease resistant to trastuzumab supports the need of larger trial to confirm a role of this combination to delay acquired trastuzumab resistance.

[Title]: Combination chemoimmunotherapy with pentostatin, cyclophosphamide, and rituximab shows significant clinical activity with low accompanying toxicity in previously untreated B chronic lymphocytic leukemia.
[Abstract]: Building on the prior work of use of pentostatin in chronic lymphocytic leukemia (CLL), we initiated a trial of combined pentostatin (2 mg/m2), cyclophosphamide (600 mg/m2), and rituximab (375 mg/m2) for 65 symptomatic, previously untreated patients. Of 64 evaluable patients, 34 (53%) were high Rai risk, 71% were nonmutated for the immunoglobulin heavy-chain variable region gene, 34% were CD38+, and 34% were ZAP-70+. Thirty patients (52%) had one anomaly detected by fluorescence in situ (FISH) hybridization, and 21 (36%) had complex FISH defects. Thirty-eight patients (58%) had grade 3+ hematologic toxicity but minimal transfusion needs and no major infections. Responses occurred in 58 patients (91%), with 26 (41%) complete responses (CRs), 14 (22%) nodular partial responses (nodular PRs), and 18 (28%) partial responses (PRs). Many patients with a CR also lacked evidence of minimal residual disease by 2-color flow cytometry. Examination of prognostic factors demonstrated poor response in the 3 patients with del(17p). In contrast, we found this regimen was equally effective in young versus older (&gt;70 years) patients and in del(11q22.3) versus other favorable prognostic factors. Thus, this novel regimen of pentostatin, cyclophosphamide, and rituximab for previously untreated patients with CLL demonstrated significant clinical activity despite poor risk-based prognoses, achievement of minimal residual disease in some, and modest toxicity.

[Title]: Genotype of thymidylate synthase likely to affect efficacy of adjuvant 5-FU based chemotherapy in colon cancer.
[Abstract]: Thymidylate synthase [TS, (EC 2.1.1.45)] is the target enzyme in 5-fluorouracil treatment. Recently, the DNA polymorphism of this gene has been found to affect TS protein (pTS) expression. However, no prospective studies have been performed to evaluate the influence of this polymorphism on the clinical efficacy of 5-FU-based adjuvant chemotherapy for colorectal cancer (CRC). In this study, we investigated the genotype of TS and immunopathological findings of pTS in 161 colon cancer specimens from patients who were registered in a prospective adjuvant immunochemotherapy clinical trial. The clinical course and prognosis of these patients were checked after the study had been completed. This study comprised 11 (6.8%) cases of 2R/2R, 40 (24.8%) of 2R/3R, and 110 (68.3%) of 3R/3R genotypes. All of the 2R/2R cases were still alive at the time of analysis although this finding was not statistically significant. In this prospective examination on a randomized controlled trial, the patients with colon cancer of the 2R/2R TS genotype may be good responders to 5-FU-based adjuvant chemotherapy. Furthermore, differences in the proportions of the TS genotypes can account for the interracial differences in the adverse effects of 5-FU-based chemotherapy.

[Title]: Polymorphisms of the ABCB1 gene are associated with the therapeutic response to risperidone in Chinese schizophrenia patients.
[Abstract]: P-glycoprotein, a product of the ATP-binding cassette B1 (ABCB1) gene, plays an important role in absorption and distribution of drugs. The brain entry of risperidone and 9-OH-risperidone is greatly limited by P-glycoprotein, which implies that the functional polymorphisms of ABCB1 in humans may be a factor contributing to the variability in response to risperidone. The present study was therefore designed to examine whether polymorphisms of the ABCB1 gene are related to therapeutic response. For this purpose, 130 Chinese schizophrenia patients undergoing risperidone treatment were recruited. Plasma drug concentrations were monitored and clinical symptoms were evaluated using the Brief Psychiatric Rating Scale (BPRS) before and 8 weeks after the treatment. Association tests between genotypes and percentage improvement in total BPRS scores were performed using analyses of variance. Our results show that genotyping C1236T may help to predict the efficacy of risperidone treatment on the basis that patients with the TT genotype showed greater improvement than those with other genotypes on the overall BPRS (F = 3.967, p = 0.021), while other polymorphisms, including rs13233308, G2677T/A and C3435T polymorphism, did not show any association with the response to risperidone. These results showed suggestive evidence that genetic variation in the ABCB1 gene may influence the individual response to risperidone.
