Of the main Workshop, and was given by Veronica Miller, the director of the Forum. [1] Nearly two million people receive ARV thanks to recent treatment access programmes. The majority receive drugs for which the side-effects are well described, but which are no-longer recommended as first-line therapy in US treatment guidelines. The lack of information on safety and tolerability from these rollout problems is disturbing. Studies reported at medical conferences are largely from smaller single investigator sites. Virologic and clinical results are optimistic, but the side-effects generally also reflect earlier use of these treatments in the economically developed countries. There is certainly no indication that treatments should be any safer in these programmes than in a Western setting. In fact, the likelihood is a higher incidence of toxicity, driven by patients starting treatment at more advanced disease stage when tolerability is worse. This may be complicated by overlapping of side effects with symptoms of other illnesses, and by a healthcare workers who have less experience in the use of HAART. In the case of stavudine, the side effects are often irreversible lipoatrophy, neuropathy and lactic acidosis ; , and so problematic that the drugs are rarely used in Western countries. This may also become the case with AZT, as anaemia frequently complicates use of AZT as an alternative first-line choice. Many doctors and advocates recognise the importance of switching away from d4T in resource-limited settings. However, this is unlikely to occur given the additional cost, unless there are adequate data. A proposal to start collecting data now, even while advocating for change, will provide the necessary support for the range of healthcare providers funders, governments and healthcare systems to justify additional costs for safer and more tolerable treatment. WHO and the Global Fund were invited to the meeting but did not attend. The concern was also expressed that the goal of `numbers on treatment' now drives access programmes both on national and international agendas, at the expense of individual patient care. Speakers at both meetings highlighted the importance of including data and safety provision within all programmes and of funders including PEPFAR and GFATM recognising and supporting this. Lipoatrophy and neuropathy are stigmatizing and debilitating no matter which country you receive your treatment in. Fatal side-effects including lactic acidosis and hepatic failure will similarly contribute to undermining the benefits that ARV treatment undoubtedly provides. Using treatment with high levels of toxicity will only build problems for the future. No-one expects any of the corrective procedures to ever become available. These patients trust their doctors, just like patients in the West. Collecting accurate data on the incidence of side effects in roll-out programmes will also provide a clearer picture of the overall benefits over the risks for the majority of people who use ARV treatment. The Forum meeting included presentations on the importance of long-term monitoring, regulatory considerations, agreements on standardisation on the way that data will be collected and use of both traditional and newer technologies SMS, mobile phone, and internet ; . A working group from the meeting will take this project forward and zerit.

New Aids Therapy for Children The Nation, Kenya April 28, 2005 Nelly Thece Nairobi For the first time, an easy-to-use fixed-dose triple combination treatment for children infected with HIV has been developed with plans already underway to have it registered in Kenya. Trading under the brand name Emtri, the triple combination oral suspension- lamivudine, stavudine and nevirapine - was launched in India recently by former Zambian President Dr Kenneth Kaunda. Speaking to Horizon in Nairobi last week, Mr A K Khanna, the Executive Director of Emcure Pharmaceuticals Limited of India who have developed the new preparation, said they propose to sell the product at no profit to Africa and other developing countries, 'as our contribution in the fight against the scourge.' "We have done estimates and are confident we can offer the drug at no profit. We are able to cover the estimated number of children infected with the virus, in any case some for practical reasons will not be using our preparation, " he said. There are about 100, 000 children infected with HIV Aids in Kenya according to recent World Health Organisation estimates. The small number of children infected and most of them in poor countries make them an unattractive client segment for most drug companies to invest in. Drug companies have little interest in developing or marketing paediatric formulations adapted to poor countries, such as fixed-dose combinations or breakable or chewable tablets. Medecins Sans Frontieres MSF ; has already demonstrated that treating children with HIV Aids is much more expensive and difficult than treating adults. Simplified ways to treat HIV Aids in adults have become available to patients in developing countries within the past two years. Most adult patients in developing countries now take either a triple fixed-dose combination treatment one pill twice a day or one double combination plus a third drug. But neither the triple nor double combinations are available in dosages for children. When childhood doses are available, they come at a premium. Launay O et al. Nevirapine or lamivudine plus stavudine and indinavir: examples of 2-class versus 3-class regimens for the treatment of human Dr Caroline Sabin, Royal Free Hospital UK-CAB - Nov 2003- i-Base immmunodeficiency virus type 1. Clin Infect Dis 2002 35: 1096-1105 and tegaserod. Higher DHA and EPA levels were significantly linked to a longer period of remission and survival time for canines with Stage III lymphoma.24 Although this study was on canines, not humans the results are significant enough to indicate the use of DHA and EPA in this patient. EPA and DHA will also have a positive impact on his cholesterol and asthma. In a cholesterol study, 16 male patients consumed 5 gms of MaxEPA 1.5 gms of EPA DHA ; daily for 2 months then switched to 5 grams omega 6 rich vegetable oil per day. After the EPA, total cholesterol and triglycerides significantly decreased while HDL significantly increased. Conversely, there were only minor improvements in the vegetable oil trials.25 Kombu, is traditionally used to treat lymphatic swellings, heart pain, blood clots, reduce tumors and tumor growths, cools and soothes the lungs, relieves coughing and asthma, aids in weight loss, increases depth of breath and it greatly increases the nutritional value of food prepared with it. 26 It should replace salt in the diet and can be kept in a salt shaker on the table. It has a high mineral content and is high in iodine. When cooked with beans it helps to soften and break down there tough fibers. The analyzed nutritive composition of Kombu reveals the presence of all essential amino acids. The values of essential amino acid ratios of analyzed algae exceed the ratios of reference proteins suggested by FAO WHO UNU, except for tryptophan. Iodine, the most important component of sea vegetables is present in high amounts as well as the vitamins B1, B2, B6, niacin and Beta-carotene. Mineral content was high, while the presence of heavy metals was negligible.27 Kombu is able to provide a rich source of vitamins, minerals and protein that combines well with beans. It is also a nontoxic source of iodine, which is why I did not include the iodine in the lymphatic tincture. Iodine is used with lymphatic stasis in asthma, atherosclerosis, and as an antiviral, antifungal and antibacterial. It is also involved in thyroid hormone synthesis.28 Reishi mushrooms should be used in his diet daily. They have been shown to be an immunomodultor and antiviral specifically for EBV.29 30 It has been found that Reishi has an immune suppressive role on the functions of T and B cells when they are being overstimulated, demonstrating its immunomodulating abilities. A multivitamin is included to ensure the patient is getting a balanced ratio of vitamins, minerals and antioxidants. I like to use botanical formulas in tincture form because of their rapid absorption and ease of use for patients. The lymph formula is used to move the lymph, has anticancer properties, to decrease lymphatic swellings, and cleanse the blood. The second botanical formula is a lung, cardiovascular and anti cancer formula, to strengthen his cardiovascular and respiratory health as well as inhibit cancer growth. Hydrotherapy has a long history of use by naturopathic physicians to improve circulation and stimulate immune function. The easiest from is to simply use cold water for 3-5.

The incidence of hyperlactatemia in stavudine-treated patients has been estimated to be 2% per year and tibolone. Simplified antiretroviral dosing as effective as twice daily dosing, Joene Hendry, AIDS 2000; 14: 2485-2494. An open label analysis of stavudine, didanosine and nevirapine in two dosing regimens in 94 adult treatment-nave patients with CD4 + counts greater than 500 cells per micro liter and viral loads greater than 5000 copies per ml. The patients were randomized to either 40 mg wtavudine b.i.d., plus once daily 400 mg didanosine and 4000 mg nevirapine or 40 mg stavueine b.i.d., plus 200 mg didanosine and 200 mg nevirapine b.i.d. After 12 months 73% of the study population had viral loads less than 200 copies per ml. Clinical Efficacy of Monotherapy with Ztavudine Compared with Zidovudine in HIV infected, Zidovudine in HIV-infected, Zidovudine-Experienced Patients. A Randomized Double-Blind Controlled Trial; Spotswood L. Sprunce; Andrew T. Pavia; John W. Mellors et al.; Annals of Internal Medicine, 11997, 126 5 ; , 355-363. The objective of the study was to evaluate the clinical effect of stavudine monotherapy in 822 HIV-infected adults who had 50 to 500 CD4 + cells mm3 and had previously received at least 6 months of zidovudine treatment. The primary endpoint was clinical progression, which was defined as all occurrences of acquired immunodeficiency syndrome AIDS ; -defining events or deaths. Patients receiving stavudine reached clinical end points at a rate of 26 per 100 personyears compared to 32 per 100 person years for patients receiving zidovudine. The trial showed that treating HIV-infected adults with stavudine compared to zidovudine therapy significantly decreases the rate of clinical progression. The risk of death was reduced by 26% among stavudine recipients. Combination therapy with stavudine plus didanosine in children with human immunodeficiency virus infections; Pediatrics; 1999; 103 5 62 The objective of the study was to evaluate the safety, tolerance and antiviral activity of combination therapy with stavudine plus didanosine in symptomatic HIV-infected children. A total of 108 children were enrolled with a mean age of 5 years. The investigators conclude that combination therapy with stavudine plus didanosine is safe and well tolerated by HIV-infected children, producing durable but incomplete suppression of virus replication.

Equivalence was predefined as a stratum weighted 95% CI with a lower limit of -10%. Although equivalence was not achieved for the primary end point at week 48, it was demonstrated using the more stringent secondary analysis, the proportion with HIV RNA level of less than 50 copies mL ITT, M F, antiretroviral Switch F ; at week 48. Equivalence was also demonstrated in secondary analyses using the ITT, M F, antiretroviral Switch F for both HIV RNA levels of less than 400 copies mL and less than 50 copies mL at weeks 96 and 144, respectively. In the ITT, M F analyses, equivalence between the 2 regimens was demonstrated for the proportion of patients achieving HIV RNA levels of less than 400 copies mL and less than 50 copies mL at weeks 48, 96, and 144 Table 2 ; .

Accessing drugs in government hospitals is usually conducted through DRFs. Some states, and sometimes individual hospitals, are given the freedom to purchase drugs that are urgently needed from suppliers. Private hospitals and sometimes community pharmacies manage their drug supplies independent of DRFs. LUTH, for example, bases its drug selection on the EDL and then sources its drug supplies from government donations secured by competitive bidding--open tenders, local purchase orders, or direct purchase, whereby multinational companies are usually favored ; , donations from pharmaceutical companies, World Bank projects, and NGOs Anyika, 1998 ; . Anyika 1998 ; stated that the cost-recovery of DRFs could be delayed from one to two years. Eniojukan et al. 1997 ; reported that out of 50 hospitals surveyed, only 60 percent operated a DRF in 1995, and that pharmacy departments were lacking in specialized clinical services. Additionally, none offered patient education clinics, drug-use evaluations, and pharmaco-economic evaluations; and few offered patient and drug therapy monitoring, such as patient review charts or patient medication profiles. Eniojukan et al. 1997 ; concluded that these gaps were due to an absence of well-defined departmental objectives and aims; lack of well-defined standards and guidelines for pharmaceutical practice; and lack of vision of what pharmaceutical practices and services should provide. Community pharmacists are placed at PHC levels. Eniojukan and Adeniyi 1997 ; found that community pharmacists are not well integrated into PHC programs, and most community pharmacists surveyed 90% ; believed that the government has no defined role in PHC programs for pharmacists. The WHO recommends that pharmacists be involved in training community workers responsible for the management of pharmaceutical services at local levels. While community pharmacists are perhaps well suited for this role, they are completely left out of this function Eniojukan and Adeniyi, 1997; Tayo 2001.

Song S-I, Daneman D, Rovet J. The influence of etiology and treatment factors on intellectual outcome in congenital hypothyroidism. J Dev Behav Pediatr 2001; 22: 376-84. SUMMARY Background Early treatment of children with congenital hypothyroidism is very effective in preventing major developmental delay, but school achievement may nonetheless be delayed, as for example reported by Leger et al. on the opposite page. More detailed studies of these children have revealed that some have cognitive impairment, including limitations in attention, language, and memory. This study was done to determine the relationships between specific cognitive abilities and the severity and adequacy of treatment of children with congenital hypothyroidism. Methods The study subjects were 65 children 7 to 12 years old mean, 9 years; 37 girls and 25 boys ; with congenital hypothyroidism detected by neonatal screening between 1986 and 1992. They were recruited from among all children of this age number not stated ; treated at the Hospital for Sick Children in Toronto, Canada. Among them, 18 had no detectable thyroid tissue athyreosis ; , 27 had ectopic thyroid tissue, and 17 had normally located thyroid tissue. The mean SD ; age at which thyroxine T4 ; treatment was initiated was 1729 days; the initial dose of T4 was 92 g kg day. The children were evaluated regularly for 3 years. The tests done for the study included the Vocabulary, Arithmetic, Coding, and Symbol Search subtests of the Wechsler Intelligence Scale for Children, the Attention Executive, Language, Visuospatial, and Sensorimotor domains of a neuropsychological test for children, and the Children's Memory Scale. Results The clinical characteristics, serum thyrotropin TSH ; concentrations, and initial T4 doses were similar in the children with athyreosis, ectopic thyroid tissue, and normally located thyroid tissue, but the children with athyreosis COMMENTARY and zerit. 10. BOTH p53 MUTATION AND NUCLEAR ACCUMUL ATION OF WILD-TY PE PROTEIN IS ASSOCIATED WITH IN VITRO SENSITIVITY TO CCNU AND VINCRISTINE VCR ; BUT NOT DOXORUBICIN DOX ; IN SHORT-TERM CULTURES DERIVED FROM MALIGNA NT ASTROCYTOMA Ashmore SM, Warr TJ, Luxsuwong M, Thomas DGT, Darling JL; Department of Neurosurgery, Institute of Neurology, University College London, Queen Square, London, UK The p53 gene is commonly mutated in astrocytic gliomas and as it plays a role in maintaining genomic stability and the regulation of apoptosis it is likely to play an important role in modulating therapeutic sensitivity of these tumours. The purpose of this investigation was to examine the relationship between p53 mutation, endogenous nuclear p53 protein accumulation and sensitivity to cytotoxic drugs. A panel of short-term cultures derived from 14 glioblastomas, two grade III astrocytomas and an established cell line, U251MG, were assessed for sensitivity to CCNU, VCR and DOX using an intermediate duration MTT assay. These cultures were stained for p53 protein accumulation using three antibodies which recognise mutant and wild-type forms of the protein and screened for mutations in exons 4 to 9 the p53 gene using SSCP analysis and sequencing. Five of 17 cultures 29% ; had mutations in the p53 gene and all of these had evidence of p53 protein accumulation in the nucleus using mutantspecific antibody Pab240. A further four cultures had nuclear accumulation of p53 protein but without evidence of p53 mutation. There was a marked relationship between the presence of a p53 mutation and sensitivity to CCNU and vincristine but not to DOX. It was also clear that those cultures without p53 mutation, but with endogenous accumulation of nuclear p53 protein, were also sensitive to CCNU and VCR. This suggests that in malignant astrocytoma, sensitivity to CCNU and VCR occurs through two separate mechanisms, one involving p53 mutation and the other dependent on endogenous accumulation of wild-type p53 protein.
