Harmless selection of genetically manipulated human stem keratinocytes T Magnaldo1, V Bergoglio1, E Warrick1, F Larcher2, O Chevallier1, M DelRio2 1CNRS, Villejuif, France 2CIEMAT, Madrid, Spain Ex-vivo gene therapy of monogenic and recessively inherited genodermatoses prone to cancer require the selection of transduced epidermal keratinocytes in a manner compatible with skin graft perspectives. We have set up a selection system which aims at: i-preserving growth and differentiation potentials of transduced keratinocytes, ii-reduce the risk of immune response in grafted patients, iii-maintain sustained expression of the corrective gene. In this system, selection is based on ectopic expression of the small cell surface marker CD24 in proliferative keratinocytes. In human epidermis, CD24 is normally expressed in post mitotic, differentiated keratinocytes. Several primary strains of normal keratinocytes could be successfully transduced using a CD24-IRES-GFP MoMLV retroviral viral vector. CD24-selected cells could be passaged serially over more than one year, attesting the conservation of stem cell growth potential. Reconstruction of organotypic skin cultures using transduced cells, indicated normal differentiation and proliferation capacity. Transduced cells were grafted onto the nu nu athymic mouse and regenerated a full thickness, normally differentiated epidermis, over a period of 20 weeks. Expression of the GFP reporter gene was maintained without attenuation. The encouraging results strongly stimulate our prospects of genetic correction of epidermal keratinocytes from patients suffering from the DNA repair deficient cancer prone disease, xeroderma pigmentosum or for any other genodermatose candidate for ex vivo cutaneous gene therapy. In addition, our system now allows any application of long term and harmless gene transfer such as gene extinction or mutation expression in human primary cells. HIV-2 ; . Fifty-one out of 320 samples 16% ; were HIV-1 positive. The study population never received any antiretroviral therapy, per their interviews with the research team. The government of India has started antiretroviral therapy in highrisk states of India in accordance with the WHO 3 by 5 program. As West Bengal [Calcutta is the state capital] is a lowprevalence [in the true sense, concentrated-epidemic] state, antiretroviral therapy has just been initiated. ; Peripheral blood mononuclear cells PBMC ; were separated from whole blood by Ficoll-Hypaque gradient centrifugation 2 ; , and the DNA was extracted by using the QIAamp DNA blood mini kit 250 QIAGEN, Germany ; according to the manufacturer's protocol.

Since July 2001, we have managed 55 HIV-1infected pregnant women. At the time of manuscript preparation, 7 patients remain undelivered. Of the 48 delivered patients, 23 patients 48.9% ; received antepartum chemoprophylaxis with nevirapine-based antiretroviral therapy. The demographic and clinical characteristics of these nevirapine recipients are summarized in Table 1. Seventeen of 23 73.9% ; HIV-1 infected pregnant women were antiretroviral treatmentnaive with all being nevirapine-naive. Twenty patients 87% ; had entry CD4 counts greater than 250 cells L. Only one patient presented with oral and esophageal candidiasis at the initial prenatal care clinic visit. All patients had normal baseline ALT and AST levels at the start of nevirapine therapy. One patient 4.4% ; started the nevirapine-containing regimen preconceptionally, whereas the other 22 started during pregnancy: 7 patients 30.4% ; at less than 14 weeks, 10 patients 43.5% ; between 14 weeks and less than 27 weeks, and 5 patients 21.7% ; between 27 and 32 weeks. The fixed-dose combination, zidovudine 300 mg lamivudine 150 mg Combivir; GlaxoSmithKline, Brentford, Middlesex, UK ; , given twice daily, was the most common dual nucleoside analogue drug prescribed during pregnancy. Oral nevirapine was administered at 200 mg daily for the first 2 weeks, then increased to twice daily. Adverse events were observed in 3 13% ; of the 23 subjects. Two patients developed drug rash, eosinophilia, and systemic symptoms, with more than grade 23 ALT and AST elevation. One of these 2 patients developed clinical hepatitis and renal failure. The clinical hepatitis resolved 12 weeks after discontinuing nevirapine. There is a dearth of well-executed, published, peer-reviewed, randomized, placebo-controlled trials and comparator trials involving periurethral injectables.76 When strict objective and subjective definitions of cure and cure and rifater.

The program enrolled 21, 755 adults over a 19 month period ending November 2005. Some of the major findings: 73% of patients were WHO stage III or IV of those with documented staging ; mean CD4 count at entry: 143 75% of all patients were started on ART mortality rate within 90 days of starting ART: 26 per 100 patient-years; mortality rate after 90 days of starting ART: 5 per 100 patient-years mortality risk was predicted by commonly measured clinical and immunologic factors CD4 count, stage, body mass index, anemia, poor adherence ; The study concludes that massive scale-up of HIV and AIDS treatment services with good clinical outcomes is feasible in primary care settings in sub-Saharan Africa.

That they demonstrated the feasibility of antiviral therapy in patients. They also sustained interest in a continuing search for more selective agents. By the late 1970s, it was known that most human pathogenic viruses possess enzymes coded by the viruses themselves and not present in uninfected cells 327 ; . Most of these enzymes are involved in viral nucleic acid synthesis, as discussed below. Their discovery represented a major advance in antiviral therapy by making it possible to direct efforts at finding specific inhibitors of these enzymes rather than nonspecific inhibitors of viral growth in cell culture. Replication of viruses can be divided into several steps: i ; attachment to the cell, ii ; penetration, iii ; uncoating of nucleic acid, iv ; transcription and translation of early regulatory ; proteins, v ; nucleic acid synthesis, vi ; synthesis of late structural ; proteins, vii ; assembly of mature virions, and viii ; release from the cell for an example, see Fig. 2 ; . All of these steps are potential targets for interference, although viral attachment, penetration, uncoating, assembly, and release closely resemble normal cellular processes and are thought to be carried out, in many instances, by cellular enzymes 210 ; . It is the point of nucleic acid synthesis that viral processes diverge most from their cellular counterparts and are most likely to require virus-specified enzymes. This is because eukaryotic cells contain doublestranded DNA and, when they replicate, make new DNA from the parental DNA template in the cell nucleus Fig. 3 ; . In addition, they transcribe mRNA from DNA and transport it into the cytoplasm, where proteins are translated. Viruses, on the other hand, may contain DNA or RNA as their genomic material, and the nucleic acid may be double or single stranded, circular or linear, and segmented or in one continuous piece. RNA may be either positive or negative stranded having the same sense or direction as mRNA, and thus directly translatable, or having the opposite sense and not directly translatable ; . Viruses may replicate in the nucleus, in the cytoplasm, or in both. Despite these differences from their cellular hosts, viruses must be able to fit into host cell synthetic pathways if they are to replicate successfully. They must present to the cell either a form of DNA that can be transcribed directly into mRNA or a form of mRNA that the cell can recognize and translate into proteins 390 ; . Many different pathways have evolved by which viruses accomplish this; some examples are shown in Fig. 3. Retroviruses, for example, carry single-stranded duplex RNA as their genomic material and, when infecting cells, must supply a virus-encoded reverse transcriptase to transcribe this RNA and roxithromycin. The statistical comparison of mortality between the groups with sympathetic overactivity receiving three different drug regimens showed no significant difference. Aplastic anemia has been reported in 1 in 2, 000 to 5, 000 patients receiving the drug and reboxetine.
Last year saw a significant step in the battle against antisocial behaviour with the formation of the Safer Neighbourhoods Team in April. Taking a more focused multi-agency approach towards the causes, the team makes full use of the additional measures contained within the Antisocial Behaviour etc Scotland ; Act 2004. The team has two main elements the Safer Neighbourhoods Co-ordination team based at Headquarters with a Force-wide focus on antisocial behaviour, and a team of four beat officers who focus on problem areas in Fife. The headquarters-based team has taken forward aspects of the Force and Fife Council's joint strategy to tackle antisocial behaviour and quality of life issues. Through the early identification of problems, it has initiated preventative measures including mediation, warning letters and acceptable behaviour agreements. Overseen by a Safer Neighbourhoods Manager, the team consists of representatives from the Housing Investigation Team, the Racial Incidents Co-ordination Team, Victim Support Fife and Fife Fire and Rescue Fire Safety Team. The team is supported by a community analyst and clerical assistant. On the operational side, the Force received funding from the Scottish Executive to recruit four extra police officers to operate in the most problematic areas of Fife in terms of antisocial behaviour and volume crime. The areas were chosen after consultation with the community and analysis of crime trends such as drugs misuse and general antisocial behaviour. This is a community-focused approach and the officers' key role is to increase public confidence, deal with complaints from the public and target street-level drug dealing. To date, the operational team has worked in Templehall, Halbeath and Methil. In two of the areas there has been a reduction in antisocial behaviour, while in the third, there have been increased calls from residents previously unwilling to report incidents to the police. The team has issued 2, 027 warning letters and five ASBOs have been obtained against the main offenders in these areas. Using the new antisocial behaviour powers, Fife was the first authority to seize a motor vehicle in May, with a further 15 seized since then and 201 vehicle seizure warnings issued. Age, sex, race, transmission risk group, main source of medical payment ; and immunologic CD4 + cell count ; variables. We did not find statistically significant differences in several possible confounders, such as geographic site municipal water source9 ; and drugs considered unrelated to development of cryptosporidiosis acyclovir and trimethoprim-sulfamethoxazole ; , that might be indexes of access to medical care data not shown ; . There are unavoidable limitations; these data were derived from an observed cohort, not a controlled clinical trial, and unmeasured factors may confound associations. The 3 drugs, recommended in HIV patients only for prevention and treatment of MAC, 10 may have been differentially prescribed and used by HIV patients in this study. However, patients who did and did not receive MAC drugs did not differ markedly in demographic or immunologic profiles Table 1 ; , and our analyses controlled for these variables and others. Because we lacked an absolute standard or another commonly used test for Cryptosporidium infection, we do not know if some patients taking macrolides had suppressed and undetectable stool organisms, yet suffered from cryptosporidiosis. Still, only a high rate of "false-negative" stool examination results--and that occurring in persons suffering from disease despite undetectable stool C parvum oocytes--would negate the large and robust prophylactic efficacy of clarithromycin and rifabutin seen. Of factors possibly confounding the observed protective effect, host immunologic function is putatively most important. Cryptosporidial diarrhea is less likely in those with high or increasing CD4 + cell counts.11, 12 Besides limiting our analyses to those with a CD4 + cell count of less than 0.075 109 L, the time-dependent regression model controlled for this factor. Also, means of most recent CD4 + cell counts of those with or without MAC prophylaxis or treatment were both about 0.040 109 L. Thus, no confounding variable--such as combination antiretroviral or protease inhibitor use not approved for use or available generally until after periods of observation in this analysis ; --was detected that would enhance immunologic protection. Data regarding biologic mechanisms and efficacy of these drugs are relatively scant and inconclusive. Some semisynthetic macrolides may reduce cryptosporidial oocyst load in stools of infected persons13, 14: clarithromycin and azithromycin activity against Cryptosporidium has been seen in vitro and in experimental models.2 Lower activity of clarithromycin vs azithromycin in animal models15, 16 may result from animal inability to produce the active 14-hydroxy386 JAMA, February 4, 1998--Vol 279, No. 5 and sodium.
Contraindicated drugs in pregnancy and changes in antiretroviral concentrations intrapartum, as well as interactions with oral contraceptive pills are also important issues to consider. Good to know: some physicians may prescribe combivir because of its easy dosing, even if retrovir plus epivir may not be the best two nucleosides for a particular individual and stavudine.

Researcher Sarah Conklin told the conference, "A number of previous studies have linked low levels of Omega-3 to clinically significant conditions such as major depressive disorder, bipolar disorder, schizophrenia, substance abuse and attention deficit disorder. However, few studies have shown that these relationships also occur in healthy adults. This study opens the door for future research looking at what effect increasing Omega-3 intake, whether by eating Omega-3 rich foods or taking supplements, has on people's moods.
Survival was observed between responders 55% of patients alive at four years ; and non-responders median survival six months ; P 0.002 ; . However, in this study, no signicant dierence was observed between patients who received AZT IFN as rst line therapy or after chemotherapy. This novel approach in ATL therapy raises the important question of the mechanism of action of the combination of AZT and IFN. In a recent in vitro study, we reported compelling evidence that the therapeutic eect of AZT IFN is not through a direct cytotoxic eect of these drugs on the leukemic cells.26 A direct anti-viral eect may be considered. AZT was shown to suppress the transformation of normal lymphocytes cocultured with HTLV-I transformed cell lines27 and inhibited HTLV-I replication and expression in a rabbit model of ATL.28 Modulation of anti-viral immunity represents an interesting alternative hypothesis. In one patient we have observed the presence of a cutaneous inltration by CD8 + non tumoral cells resulting in epidermolysis at the initial tumor site. Unfortunately, the majority of the patients relapse even on long term maintenance therapy indicating that even though AZT IFN shows a high response rate, it rarely cures patients. Therefore, after achievement of CR or very good PR with AZT IFN, further therapy is warranted. Recent reports suggest the possibility of prolongation of remission with oral etoposide or acute lymphoblastic leukemia-type of maintenance chemotherapy.29 Allogenic or autologous bone marrow transplantation may be considered in young patients with an extremely careful attitude toward opportunistic infections. Immunotherapy with monoclonal antibodies or additional anti-retroviral agents such as lamuvidine, which was recently tested in tropical spastic paraparesis HTLV-I associated myelopathy TSP HAM ; patients30 may be added to AZT IFN to prevent relapse. Finally, following our recent demonstration that arsenic trioxide As ; and IFN act synergistically to induce Tax degradation followed by cell cycle arrest and apoptosis in HTLV-I transformed and fresh ATL cells, 31, 32 we initiated a phase II trial of As IFN in relapsed or refractory ATL patients.

59 percent ; and cosmetics 47 percent ; . As well, fewer Canadians 5 percent ; thought prescription medicines were seldom never safe, while 9 percent thought non-prescription medicines and 13 percent thought cosmetics were seldom never safe. Moreover, respondents indicated that non-prescription medicines were less effective than prescription medicines. Approximately half believed that non-prescription medicines were always often effective; 65 percent thought that prescription medicines were always often effective. In summary, the available evidence appears to indicate that consumers do indeed distinguish differences between OTC and prescription medicines. By extension, a concern appears to exist whereby the public may not consider medicines available without prescription as full-fledged `medicines', ones that require a level of vigilance during use. Location of sale may be a factor in the development of such perceptions. Impressions held of OTC medicines may be important pre-determinants of actual behaviour, where failure to consider such agents as important medicines requiring due care, could expose the public to important drug-related risk.

Two New Combination Drugs Approved On August 2, 2004, the Food and Drug Administration FDA ; approved two once-daily combination pills: Epzicom, made by GlaxoSmithKline, and Truvada, produced by Gilead. Both drugs consist of two nucleoside nucleotide reverse transcriptase inhibitors NRTIs ; . Epzicom is a combination of Glaxo's 3TC lamivudine, Epivir ; and abacavir Ziagen ; , while Truvada contains Gilead's tenofovir DF Viread ; and FTC emtricitabine, Emtriva ; . The new drugs are designed to help people simplify their anti-HIV regimens. However, the twodrug formulations must be used with at least one other antiretroviral. Some generic anti-HIV drugs produced outside the U.S. combine three drugs of more than one class, and can be taken alone as a complete regimen. Norvir Price Hike Here to Stay? On August 4, 2004, the National Institutes of Health NIH ; refused to allow Essential Innovations, a small nonprofit company, to make cheaper, generic copies of Norvir. Norvir is the patented form of Abbott Laboratories' protease inhibitor PI ; ritonavir, a drug rarely taken at full strength but widely used in small doses to boost other PIs in anti-HIV drug regimens. Abbott raised the price of Norvir by over 400% this past December. Essential Innovations then asked the federal government to override Abbott's Norvir patent, arguing that the medicine was developed in part with taxpayer money and was now unreasonably priced. The NIH said that the issue should be decided by Congress, but action at the Congressional level is unlikely. Abbott insists the price hike was needed to fund their research programs. AIDS advocates counter that Abbott aimed to make their other antiHIV drug, Kaletra, the least expensive PI on the market, as Kaletra already has ritonavir built in to its formulation. Many advocates worry about the effect of the price hike on government health insurance programs and future development of anti-HIV drugs. Physicians, Congressional legislators, and the attorneys general of Illinois and New York have decried Abbott's unprecedented price increase. Yet despite a vigorous public campaign against Abbott, the federal government appears unwilling to intervene. Abbott's patent on Norvir does not expires until 2014 and ticlid and retrovir.

MANAGEMENT OF HEPATITIS B HIV COINFECTION compensated or decompensated cirrhosis. 5, 7, 11 Lamivudine should be administered with other antiretroviral agents in an HBV HIV coinfected population.1, 2, 5 The recommended dose for adults with HBV HIV coinfection is 150 mg twice daily or 300 mg daily.1, 2, 5, 7 The lamivudine 100-mg daily dose should not be used in the HBV HIV coinfected population.1, 2, 5 Lamivudine should be dose adjusted according to renal function.5, 18 Several studies have evaluated the effectiveness of lamivudine in the HBV HIV-coinfected population.19-21 One randomized, double-blind, placebo-controlled study evaluated 1895 HIV HBV-coinfected patients.19 A total of 1895 patients was included in the study, but only 1790 patients had baseline HBsAg results, done retrospectively. Of 1790 patients, only 122 were positive for HBsAg. The CD4 count ranged from 25 to 250 CD4 cells mL for the total study population. Patients were randomized to placebo, lamivudine 150 mg twice daily ; , or lamivudine 150 mg twice daily ; plus loviride 100 mg 3 times daily ; and to either zidovudine monotherapy or zidovudine plus didanosine or zalcitabine combination regimen.19 The groups that received lamivudine had greater reductions in the HBV DNA and loss of HBeAg than did the placebo group. Also, the groups receiving lamivudine achieved greater ALT normalization and reduced HIV disease progression than the placebo group did.19 Although in 1 study of 19 patients, HBV HIV-coinfected patients receiving lamivudine as a component of their antiretroviral therapy had reduction in HBV DNA 87% ; and 35% had seroconversion to anti-HBe, resistance mutations to lamivudine were reported.20 Similarly, a study by Hoff and colleagues20 evaluating 66 HBV HIV-coinfected patients who were treated with lamivudine along with other antiretrovirals found that 86.4% of patients did respond to therapy; however, resistance mutations to lamivudine were also noted in 22 33.3% ; patients.21 The occurrence of lamivudine resistance is more common in HBV HIV-coinfected patients than in those patients with HBV alone.1, 2 There is an increased risk of developing resistant strains of HBV as treatment with lamivudine is prolonged.1, 2, 5 Resistance mutations to lamivudine have been associated with exacerbations in hepatic disease, including liver failure and rises in aminotransferases. Emtricitabine is another nucleoside analogue that has activity against both HIV and HBV, but it is FDA approved only for the treatment of HIV.1, 2, 22 It is being evaluated for its activity against hepatitis B.2, 23 A 2-year follow-up study found emtricitabine's dose for HBV activity to be 200 mg.

Until more information from larger studies is available it is difficult to directly associate PI use with avascular necrosis. Osteonecrosis should be considered in HIV infected patients presenting with a groin strain. the first seven weeks of therapy. Only 3 patients 3.9% ; showed failure of initial viral suppression. There were no episodes of viral rebound in the first 48 weeks and only 4 15.4% ; by 3 years. Our study demonstrates that outcomes at least comparable to those in published trials can be achieved in a `real world' setting. This is despite a cohort with comparatively advanced HIV. Efavirenz remains a highly efficacious antiretroviral agent and is well tolerated and durable for antiretroviral nave patients. AIM To clone the cDNA fragment of human TRAIL TNFrelated apoptosis inducing ligand ; into a tetracyclineregulated gene expression system, the RevTet-On system, transduce expression vectors into a gastric carcinoma cell line-NCI-N87 and examine the effects of controlled expression of TRAIL in vitro on the gastric carcinoma cells. METHODS The full-length cDNA of TRAIL was inserted into a vector under the control of the tetracyclineresponsive element TRE ; to obtain the plasmid pRevTRETRAIL, which was transfected into a packaging cell line PT67. In addition, vector pRev-Tet On and pRevTRE were also transfected into PT67 separately. After hygromycin and G418 selection, the viral titer was determined. The medium containing retroviral vectors was collected and used to transduce a gastric carcinoma cell line NCI-N87. The resulting cell line NCI-N87-Tet On TRE-TRAIL and a control cell line, NCI-N87 Tet On-TRE, were established. TRAIL expression in the cell line was induced by incubating cells with doxycycline Dox ; , which is a tetracycline analogue. The killing effect on gastric carcinoma cells was analyzed after induction. RESULTS The recombinant plasmid pRev-TRE-TRAIL was constructed. After hygromycin or G418 selection, the producer cell lines PT67-TRE, PT67-TRE-TRAIL and PT67Tet On were obtained, with titers of about 108CFUL-1. By transducing NCI-N87 cells with retroviral vectors from these cell lines, stable cell lines NCI-N87-Tet On TRETRAIL NN3T ; and control cell line NCI-N87-Tet On TRE NN2T ; were established. The growth curves of the selected cell lines were the same with the wild type NCIN87. When Dox was added, cell death was obvious in the test groups 29%-77% ; , whereas no difference was observed in control and wild type cell lines. With the addition of a medium from the test group, human leukemia cell line Jurkat was activated till death 83% ; , indicating the secretion of active TRAIL proteins from the test cells to the medium. CONCLUSION With the use of the RevTet-On system, a.

HIV-1 persists in a latent state in resting CD4 + T lymphocytes of infected adults despite prolonged highly active antiretroviral therapy HAART ; . To determine whether a latent reservoir for HIV-1 exists in infected children, we performed a quantitative viral culture assay on highly purified resting CD4 + T cells from 21 children with perinatally acquired infection. Replication-competent HIV-1 was recovered from all 18 children from whom sufficient cells were obtained. The frequency of latently infected resting CD4 + T cells directly correlated with plasma virus levels, suggesting that in children with ongoing viral replication, most latently infected cells are in the labile preintegration state of latency. However, in each of 7 children who had suppression of viral replication to undetectable levels for 13 years on HAART, latent replication-competent HIV-1 persisted with little decay, owing to a stable reservoir of infected cells in the postintegration stage of latency. Drug-resistance mutations generated by previous nonsuppressive regimens persisted in this compartment despite more than 1 year of fully suppressive HAART, rendering untenable the idea of recycling drugs that were part of failed regimens. Thus the latent reservoir for HIV-1 in resting CD4 + T cells will be a major obstacle to HIV-1 eradication in children.
Patients for this study. The patients were recruited from the Immunodeficiency Clinic at the University of Pennsylvania if they expressed interest in participating and met the eligibility criteria of having confirmed HIV infection and being on no antiretroviral medications or a stable antiretroviral regimen for at least 3 mo. Diet Survey A registered dietitian performed a baseline diet survey and determined the prestudy dietary niacin equivalents for each participant by with the Food Processor program. Clinical Monitoring None of the patients recruited for the study had baseline wasting syndrome, dermatitis, diarrhea, or dementia; it was planned that these clinical measures would be monitored if present during the study. Nicotinamide Tablets containing 500 mg of nicotinamide were purchased from Rugby Laboratories, Inc. Norcross, GA, USA ; and dispensed with instructions to take two tablets three times a day. Routine Laboratory Testing Serum chemistries, complete blood counts, and CD4 and CD8 lymphocyte counts were performed on all patients at baseline and at the completion of their participation. Quantification of Plasma Amino Acids SSA deproteinization and high-performance liquid chromatography were used to quantify amino acids.7 Statistical Methods The significance of differences between pre- and posttreatment values were assessed with a paired t test.
