Abstract: With rational use of antiretroviral therapy (ART), human immunodeficiency virus (HIV) infection has been transformed into a chronic manageable illness like diabetes and hypertension. These guidelines provide information on state of art, evidence based approach for use of ART in Indian context. When to initiate ART? Antiretroviral therapy is indicated for all symptomatic HIV infected persons regardless of CD4 counts and plasma viral load (PVL) levels. In asymptomatic patients, ART should be offered when the CD4 counts < 200/mm3 and should be considered in patients with CD4 counts between 200-250/mm3. Therapy is not recommended for patients with CD4 count more than 350/ mm3. Involvement of patient in all treatment decisions and assessing readiness is critical before initiating ART. What to start with? A non-nucleoside reverse transcriptase inhibitor (NNRTI) based regimen is recommended for antiretroviral naïve patients. The choice between nevirapine and efavirenz is based on differences in adverse events profiles; cost and availability of convenient fixed dose combinations and need for concomitant use of rifampicin. A backbone of 2-nucleoside reverse transcriptase inhibitors (NRTIs) is combined with the NNRTI. Various combinations and ART strategies not to be used in clinical practice has been enlisted. How to follow up? Recommendations have been made for baseline evaluation and monitoring of patients on ART. These include guidelines on laboratory and clinical evaluation. A plasma viral load at 6 months after initiation of first-line ART is strongly recommended. Yearly estimation of lipid profile has been recommended. How to identify and manage ART failure? The guidelines recognize the issue of identifying ART failure late if only CD4 counts are used for monitoring. In the absence of resistance testing various second-line regimens have been enlisted. A boosted protease inhibitor based regimen is recommended in this situation to be combined with 2-NRTIs. Special situations Recommendations have been made for use of ART in HIV-TB, HIV-HBV, and HIV-HCV co-infected patients. In patients with active TB and a CD4 count < 200/mm3, initiation of ART is recommended as soon as the anti-TB treatment is tolerated. Efavirenz is the only ARV drug, which can be safely used with rifampicin. In pregnancy use of single dose nevirapine for reducing risk of mother to child transmission of HIV is not recommended, because of the risk of development of resistance. For post-exposure prophylaxis taking ART treatment history of the source patient is crucial in designing an effective regimen.

Abstract: We present the British Association for Sexual Health and HIV (BASHH) guidelines for post-exposure prophylaxis after sexual exposure (PEPSE) to HIV. This document includes a review of the current data to support the use of PEPSE, considers how to calculate the risks of HIV infection after a potential exposure, and provides recommendations on when PEPSE would and would not be considered. Other areas included are the possible impact on sexual behaviour, cost-effectiveness, and issues relating to service provision. Throughout the document, consideration is given to the place of PEPSE within the broader context of HIV prevention strategies and sexual health.

Abstract: OBJECTIVE: This consensus document is an update of antiretroviral therapy (ART) recommendations for adult patients infected with the human immunodeficiency virus (HIV). METHODS: To formulate these recommendations, a panel composed of members of the Grupo de Estudio de Sida (GESIDA; AIDS Study Group) and the Plan Nacional sobre el Sida (PNS; Spanish AIDS Plan) reviewed the advances in current understanding of the pathophysiology of HIV, the safety and efficacy findings from clinical trials, and the results from cohort and pharmacokinetic studies published in biomedical journals or presented at scientific meetings over the last years. Three levels of evidence were defined according to the source of the data: randomized studies (level A), cohort or case-control studies (level B), and expert opinion (level C). The decision to recommend, consider or not recommend ART was established in each of these situations. RESULTS: ART consisting of at least three drugs is currently the initial treatment of choice for chronic HIV infection. These regimens should include 2 NRTI + 1 NNRTI or 2 NRTI + 1 PI. Initiation of ART is recommended in patients with symptomatic HIV infection. In asymptomatic patients, initiation of ART is recommended on the basis of CD4+ lymphocyte counts per L and plasma viral load, as follows: 1) Therapy should be started in patients with CD4+ counts of < 200 cells/microL; 2) Therapy should be started in most patients with CD4+ counts of 200-350 cells/microL, although it can be delayed when CD4+ count persists at around 350 cells/microL and viral load is low; and 3) Initiation of therapy can be delayed in patients with CD4+ counts of > 350 cells/microL. The initial objective of ART is to achieve an undetectable viral load. Adherence to therapy plays an essential role in maintaining the antiviral response. Because of the development of cross resistance, therapeutic options are limited when ART fails. Genotype studies are useful in these cases. Toxicity is a limiting factor in the use of ART, although the benefits outweigh the risks. In addition, the criteria for the use of ART are discussed in situations of acute infection, pregnancy, and post-exposure prophylaxis, and in the management of co-infection of HIV with HCV or HBV. CONCLUSIONS: CD4+ lymphocyte count is the most important reference factor for initiating ART in asymptomatic patients. The large number of available drugs, the increased sensitivity of tests to monitor viral load, and the possibility to determine viral resistance is leading to a more individualized approach to therapy.

Abstract: Infection with the human immunodeficiency virus (HIV) and the development of acquired immunodeficiency syndrome (AIDS) have had a significant impact on domestic and global health, social, political, and economic outcomes. Prevention and treatment efforts to control HIV infection are more demanding than in previous decades. Achieving food and nutrition security, and managing nutrition-related complications of HIV infection and the multiple aspects of disease initiated by or surrounding HIV infection, referred to as HIV disease, remain challenges for patients and for those involved with HIV/AIDS prevention, care, and treatment efforts. Confounding clinical issues include medication interactions, coinfection with other infections and diseases, wasting, lipodystrophy, and others. Dietetics professionals, other health care professionals, and people infected with HIV will need to understand and address multiple complex aspects of HIV infection and treatment to improve survival, body functions, and overall quality of life. Individualized nutrition care plans will be an essential feature of the medical management of persons with HIV infection and AIDS.

Abstract: This report supplements the 2001 statement by the Advisory Committee on Immunization Practices (ACIP) (CDC. Vaccinia [smallpox] vaccine: recommendations of the Advisory Committee on Immunization Practices [ACIP], 2001. MMWR 2001;50[No. RR-10]:1-25). This supplemental report provides recommendations for using smallpox vaccine in the pre-event vaccination program in the United States. To facilitate preparedness and response, smallpox vaccination is recommended for persons designated by public health authorities to conduct investigation and follow-up of initial smallpox cases that might necessitate direct patient contact. ACIP recommends that each state and territory establish and maintain > or = 1 smallpox response team. ACIP and the Healthcare Infection Control Practices Advisory Committee (HICPAC) recommend that each acute-care hospital identify health-care workers who can be vaccinated and trained to provide direct medical care for the first smallpox patients requiring hospital admission and to evaluate and manage patients who are suspected as having smallpox. When feasible, the first-stage vaccination program should include previously vaccinated health-care personnel to decrease the potential for adverse events. Additionally persons administering smallpox vaccine in this pre-event vaccination program should be vaccinated. Smallpox vaccine is administered by using the multiple-puncture technique with a bifurcated needle, packaged with the vaccine and diluent. According to the product labeling, 2-3 punctures are recommended for primary vaccination and 15 punctures for revaccination. A trace of blood should appear at the vaccination site after 15-20 seconds; if no trace of blood is visible, an additional 3 insertions should be made by using the same bifurcated needle without reinserting the needle into the vaccine vial. If no evidence of vaccine take is apparent after 7 days, the person can be vaccinated again. Optimal infection-control practices and appropriate site care should prevent transmission of vaccinia virus from vaccinated health-care workers to patients. Health-care personnel providing direct patient care should keep their vaccination sites covered with gauze in combination with a semipermeable membrane dressing to absorb exudates and to provide a barrier for containment of vaccinia virus to minimize the risk of transmission; the dressing should also be covered by a layer of clothing. Dressings used to cover the site should be changed frequently to prevent accumulation of exudates and consequent maceration. The most critical measure in preventing contact transmission is consistent hand hygiene. Hospitals should designate staff to assess dressings for all vaccinated health-care workers. When feasible, staff responsible for dressing changes for smallpox health-care teams should be vaccinated, all persons handling dressings should observe contact precautions. Administrative leave is not required routinely for newly vaccinated health-care personnel unless they are physically unable to work as a result of systemic signs and symptoms of illness; have extensive skin lesions that cannot be adequately covered or if they are unable to adhere to the recommended infection-control precautions. Persons outside the patient-care setting can keep their vaccination sites covered with a porous dressing hand hygiene remains key to preventing inadvertent inoculation. FDA has recommended that recipients of smallpox vaccine be deferred from donating blood for 21 days or until the scab has separated. Contacts of vaccinees, who have inadvertently contracted vaccinia, also should be deferred from donating blood for 14 days after complete resolution of their complication. In the pre-event vaccination program, smallpox vaccination is contraindicated for persons with a history or presence of eczema or atopic dermatitis; who have other acute, chronic, or exfoliative skin conditions; who have conditions associated with immunosuppression; are aged < 1 year; who have a serious allergy to any component of the vaccine; or who are pregnant or breastfeeding. ACIP does not recommend smallpox vaccination for children and adolescents aged < 18 years during the pre-event vaccination program. Pre-event vaccination also is contraindicated among persons with household contacts who have a history or presence of eczema or atopic dermatitis; who have other acute, chronic, or exfoliative skin conditions; who have conditions associated with immunosuppression; or who are pregnant. For purposes of screening for contraindications for pre-event vaccination, household contacts include persons with prolonged intimate contact (e.g., sexual contacts) with the potential vaccinee and others who might have direct contact with the vaccination site. Persons with inflammatory eye disease might be at increased risk for inadvertent inoculation as a result of touching or rubbing the eye. Therefore, deferring vaccination is prudent for persons with inflammatory eye diseases requiring steroid treatment until the condition resolves and the course of therapy is complete. Eczema vaccinatum, a serious form of disseminated vaccinia infection, can occur among persons with atopic dermatitis and other dermatologic conditions. Potential vaccinees should be queried regarding the diagnosis of atopic dermatitis or eczema in themselves or any member of their household, or regarding the presence of chronic or recurrent rashes consistent with these diagnoses. Persons reporting such a rash in themselves or household members should not be vaccinated, unless a health-care provider determines that the rash is not eczema or atopic dermatitis. Before vaccination, women of childbearing age should be asked if they are pregnant or intend to become pregnant during the next 4 weeks; women who respond positively should not be vaccinated. Any woman who thinks she might be pregnant or who wants additional assurance that she is not pregnant should perform a urine pregnancy test on the day scheduled for vaccination. If a pregnant woman is inadvertently vaccinated or if she becomes pregnant within 4 weeks after smallpox vaccination, she should be counseled regarding concerns for the fetus. Vaccination during pregnancy should not ordinarily be a reason to terminate pregnancy. CDC has established a pregnancy registry to prospectively follow the outcome of such pregnancies and facilitate the investigation of any adverse pregnancy outcome among pregnant women who were inadvertently vaccinated. For enrollment in the registry, contact CDC at 404-639-8253. Smallpox vaccine should not be administered to persons with human immunodeficiency virus infection (HIV) or acquired immunodeficiency syndrome (AIDS) as part of a pre-event program because of their increased risk for progressive vaccinia. HIV testing is recommended for persons who have any history of a risk factor for HIV infection or for anyone who is concerned that he or she might have HIV infection. HIV testing should be available in a confidential or anonymous setting, in accordance with local laws and regulations, with results communicated to the potential vaccinee before the planned date of vaccination. Smallpox vaccine can be administered simultaneously with any inactivated vaccine. With the exception of varicella vaccine, smallpox vaccine can be administered simultaneously with other live-virus vaccines. To avoid confusion in ascertaining which vaccine might have caused postvaccination skin lesions or other adverse events, varicella vaccine and smallpox vaccine should be administered >4 weeks apart. Health-care workers scheduled to receive an annual purified protein derivative (PPD) skin test for tuberculosis screening should not receive the skin test until >1 month after smallpox vaccination. Persons with progressive vaccinia, eczema vaccinatum, and severe generalized vaccinia or inadvertent inoculation might benefit from therapy with VIG or cidofovir, although the latter has not been approved by FDA for this indication. Suspected cases of these illnesses or other severe adverse events after smallpox vaccination should be reported immediately to state health departments. VIG and cidofovir are available from CDC under Investigational New Drug protocols. Clinically severe adverse events after smallpox vaccination should be reported to the Vaccine Adverse Event Reporting System. Reports can be made online at https://secure.vaers.org/VaersDataEntryintro.htm, or by postage-paid form, which is available by calling 800-822-7967 (toll-free). ACIP will review these recommendations periodically as new information becomes available related to smallpox disease, smallpox vaccines, the risk of smallpox attack, smallpox vaccine adverse events, and the experience gained as recent recommendations are implemented. Revised recommendations will be developed as needed.

Abstract: The guidance in this report is for evaluation and treatment of patients with complications from smallpox vaccination in the preoutbreak setting. Information is also included related to reporting adverse events and seeking specialized consultation and therapies for these events. The frequencies of smallpox vaccine-associated adverse events were identified in studies of the 1960s. Because of the unknown prevalence of risk factors among today's population, precise predictions of adverse reaction rates after smallpox vaccination are unavailable. The majority of adverse events are minor, but the less-frequent serious adverse reactions require immediate evaluation for diagnosis and treatment. Agents for treatment of certain vaccine-associated severe adverse reactions are vaccinia immune globulin (VIG), the first-line therapy, and cidofovir, the second-line therapy. These agents will be available under Investigational New Drug (IND) protocols from CDC and the U.S. Department of Defense (DoD). Smallpox vaccination in the preoutbreak setting is contraindicated for persons who have the following conditions or have a close contact with the following conditions: 1) a history of atopic dermatitis (commonly referred to as eczema), irrespective of disease severity or activity; 2) active acute, chronic, or exfoliative skin conditions that disrupt the epidermis; 3) pregnant women or women who desire to become pregnant in the 28 days after vaccination; and 4) persons who are immunocompromised as a result of human immunodeficiency virus or acquired immunodeficiency syndrome, autoimmune conditions, cancer, radiation treatment, immunosuppressive medications, or other immunodeficiencies. Additional contraindications that apply only to vaccination candidates but do not include their close contacts are persons with smallpox vaccine-component allergies, women who are breastfeeding, those taking topical ocular steroid medications, those with moderate-to-severe intercurrent illness, and persons aged < 18 years. In addition, history of Darier disease is a contraindication in a potential vaccinee and a contraindication if a household contact has active disease. In the event of a smallpox outbreak, outbreak-specific guidance will be disseminated by CDC regarding populations to be vaccinated and specific contraindications to vaccination. Vaccinia can be transmitted from a vaccinee's unhealed vaccination site to other persons by close contact and can lead to the same adverse events as in the vaccinee. To avoid transmission of vaccinia virus (found in the smallpox vaccine) from vaccinees to their close contacts, vaccinees should wash their hands with warm soapy water or hand rubs containing > or = 60% alcohol immediately after they touch their vaccination site or change their vaccination site bandages. Used bandages should be placed in sealed plastic bags and can be disposed of in household trash. Smallpox vaccine adverse reactions are diagnosed on the basis of clinical examination and history, and certain reactions can be managed by observation and supportive care. Adverse reactions that are usually self-limited include fever, headache, fatigue, myalgia, chills, local skin reactions, nonspecific rashes, erythema multiforme, lymphadenopathy, and pain at the vaccination site. Other reactions are most often diagnosed through a complete history and physical and might require additional therapies (e.g., VIG, a first-line therapy and cidofovir, a second-line therapy). Adverse reactions that might require further evaluation or therapy include inadvertent inoculation, generalized vaccinia (GV), eczema vaccinatum (EV), progressive vaccinia (PV), postvaccinial central nervous system disease, and fetal vaccinia. Inadvertent inoculation occurs when vaccinia virus is transferred from a vaccination site to a second location on the vaccinee or to a close contact. Usually, this condition is self-limited and no additional care is needed. Inoculations of the eye and eyelid require evaluation by an ophthalmologist and might require therapy with topical antiviral or antibacterial medications, VIG, or topical steroids. GV is characterized by a disseminated maculopapular or vesicular rash, frequently on an erythematous base, which usually occurs 6-9 days after first-time vaccination. This condition is usually self-limited and benign, although treatment with VIG might be required when the patient is systemically ill or found to have an underlying immunocompromising condition. Infection-control precautions should be used to prevent secondary transmission and nosocomial infection. EV occurs among persons with a history of atopic dermatitis (eczema), irrespective of disease severity or activity, and is a localized or generalized papular, vesicular, or pustular rash, which can occur anywhere on the body, with a predilection for areas of previous atopic dermatitis lesions. Patients with EV are often systemically ill and usually require VIG. Infection-control precautions should be used to prevent secondary transmission and nosocomial infection. PV is a rare, severe, and often fatal complication among persons with immunodeficiencies, characterized by painless progressive necrosis at the vaccination site with or without metastases to distant sites (e.g., skin, bones, and other viscera). This disease carries a high mortality rate, and management of PV should include aggressive therapy with VIG, intensive monitoring, and tertiary-level supportive care. Anecdotal experience suggests that, despite treatment with VIG, persons with cell-mediated immune deficits have a poorer prognosis than those with humoral deficits. Infection-control precautions should be used to prevent secondary transmission and nosocomial infection. Central nervous system disease, which includes postvaccinial encephalopathy (PVE) and postvaccinial encephalomyelitis (or encephalitis) (PVEM), occur after smallpox vaccination. PVE is most common among infants aged < 12 months. Clinical symptoms of central nervous system disease indicate cerebral or cerebellar dysfunction with headache, fever, vomiting, altered mental status, lethargy, seizures, and coma. PVE and PVEM are not believed to be a result of replicating vaccinia virus and are diagnoses of exclusion. Although no specific therapy exists for PVE or PVEM, supportive care, anticonvulsants, and intensive care might be required. Fetal vaccinia, resulting from vaccinial transmission from mother to fetus, is a rare, but serious, complication of smallpox vaccination during pregnancy or shortly before conception. It is manifested by skin lesions and organ involvement, and often results in fetal or neonatal death. No known reliable intrauterine diagnostic test is available to confirm fetal infection. Given the rarity of congenital vaccinia among live-born infants, vaccination during pregnancy should not ordinarily be a reason to consider termination of pregnancy. No known indication exists for routine, prophylactic use of VIG in an unintentionally vaccinated pregnant woman; however, VIG should not be withheld if a pregnant woman develops a condition where VIG is needed. Other less-common adverse events after smallpox vaccination have been reported to occur in temporal association with smallpox vaccination, but causality has not been established. Prophylactic treatment with VIG is not recommended for persons or close contacts with contraindications to smallpox vaccination who are inadvertently inoculated or exposed. These persons should be followed closely for early recognition of adverse reactions that might develop, and clinicians are encouraged to enroll these persons in the CDC registry by calling the Clinician Information Line at 877-554-4625. To request clinical consultation and IND therapies for vaccinia-related adverse reactions for civilians, contact your state health department or CDC's Clinician Information Line (877-554-4625). Clinical evaluation tools are available at http.//www.bt.cdc.gov/agent/smallpox/vaccination/clineval. Clinical specimen-collection guidance is available at http://www.bt.cdc.gov/agent/smallpox/vaccination/vaccinia-specimen-collection.asp. Physicians at military medical facilities can request VIG or cidofovir by calling the U.S. Army Medical Research Institute of Infectious Diseases (USAMRIID) at 301-619-2257 or 888-USA-RIID.

Abstract: OBJECTIVE: New information warrants updated recommendations for the 4 central issues in antiretroviral therapy: when to start, what drugs to start with, when to change, and what to change to. These updated recommendations are intended to guide practicing physicians actively involved in human immunodeficiency virus (HIV)- and acquired immunodeficiency syndrome (AIDS)-related care. PARTICIPANTS: In 1995, physicians with specific expertise in HIV-related basic science and clinical research, antiretroviral therapy, and HIV patient care were invited by the International AIDS Society-USA to serve on a volunteer panel. In 1999, others were invited to broaden international representation. The 17-member panel met regularly in closed meetings between its last report in 2000 and April 2002 to review current data. The effort was sponsored and funded by the International AIDS Society-USA, a not-for-profit physician education organization. EVIDENCE AND CONSENSUS PROCESS: The full panel was convened in late 2000 and assigned 7 section committees. A section writer and 3 to 5 section committee members (each panel member served on numerous sections) identified relevant evidence and prepared draft recommendations. Basic science, clinical research, and epidemiologic data from the published literature and abstracts from recent (within 2 years) scientific conferences were considered by strength of evidence. Extrapolations from basic science data and expert opinion of the panel members were included as evidence. Draft sections were combined and circulated to the entire panel and discussed in a series of full-panel conference calls until consensus was reached. Final recommendations represent full consensus agreement of the panel. CONCLUSIONS: Because of increased awareness of the activity and toxicity of current drugs, the threshold for initiation of therapy has shifted to a later time in the course of HIV disease. However, the optimal time to initiate therapy remains imprecisely defined. Availability of new drugs has broadened options for therapy initiation and management of treatment failure, which remains a difficult challenge.

Abstract: OBJECTIVE: To provide an update of recommendation on antiretroviral treatment (ART) in HIV-infected adults.Methods. These recommendations have been agreed by consensus by a committee of the spanish AIDS Study Group (GESIDA) and the National AIDS Plan. To do so, advances in the physiopathology of AIDS and the results on efficacy and safety in clinical trials, cohort and pharmacokinetics studies published in biomedical journals or presented at congresses in the last few years have been reviewed. Three levels of evidence have been defined according to the data source: randomized studies (level A), case-control or cohort studies (level B) and expert opinion (level C). Whether to recommend, consider, or not to recommend ART has been established for each situation. RESULTS: Currently, ART with combinations of at least three drugs constitutes the treatment of choice in chronic HIV infection. In patients with symptomatic HIV infection, initiation of ART is recommended. In asymptomatic patients initiation of ART should be based on the CD41/mL lymphocyte count and on the plasma viral load (PVL): a) in patients with CD41 lymphocytes < 200 cells/mL, initiation of ART is recommended; b) in patients with CD41 lymphocytes between 200 and 300 cells/mL, initiation of ART should, in most cases, be recommended; however, it could be delayed when the CD41 lymphocyte count remains close to 350 cells/mL and the PVL is low, and c) in patients with CD41 lymphocytes > 350 cells/mL, initiation of ART can be delayed. The aim of ART is to achieve an undetectable PVL. Adherence to ART plays a role in the durability of the antiviral response. Because of the development of cross-resistance, the therapeutic options in treatment failure are limited. In these cases, genotypic analysis is useful. Toxicity limits ART. The criteria for ART in acute infection, pregnancy and postexposure prophylaxis and in the management of coinfection with HIV and hepatitis C and B virus are controversial. CONCLUSIONS: The current approach to initiating ART is more conservative than in previous recommendations. In asymptomatic patients, the CD41 lymphocyte count is the most important reference factor for initiating ART. Because of the considerable number of drugs available, more sensitive monitoring methods (PVL) and the possibility of determining resistance, therapeutic strategies have become much more individualized.

Abstract: There are now some 36 million people in the world infected with HIV/AIDS. It is estimated that more than 23 million of them are economically active, including 642,000 persons in Latin America and the Caribbean. In the workplace, HIV/AIDS reduces incomes, imposes added costs on companies, and undermines fundamental labor laws due to the discrimination and rejection that infected individuals suffer. In response, the International Labor Organization (ILO) has produced a document entitled An ILO code of practice on HIV/AIDS and the world of work, which is summarized in this piece. The ILO document aims to help those in the workplace to cope with the HIV/AIDS epidemic through a set of guidelines related to: (a) preventing infection, (b) managing and reducing the impact that HIV/AIDS has on the workplace, (c) delivering care and support for infected workers and, in general, to all the people affected by this epidemic, and (d) eliminating discrimination against persons who are infected or are suspected of being infected. The ILO Code is intended to help in preparing and adopting specific measures in the workplace, thus promoting dialogue and other forms of cooperation among the government, employers, workers and their representatives, workplace health and safety officers, HIV/AIDS specialists, and other interested parties. The intention is also for the Code recommendations to be implemented and integrated with national laws, policies, and programs; company or business agreements; and workplace policies and action plans. This ILO Code is an important step in the struggle against HIV/AIDS. Aimed at governments, employers, and workers throughout the world, the Code recommendations constitute a useful tool in addressing the problem of HIV/AIDS in the workplace, in a just manner. As a "motor" of society, work cannot remain separated from issues of such great social impact.

Abstract: Viral drug susceptibility is associated with virologic response to new treatments. Standardized drug resistance tests are now available, and data from some clinical trials suggest that the use of drug resistance testing may be associated with improved virologic outcome. However, drug resistance testing is complex in terms of performance, interpretation and clinical application. HIV-1 drug resistance testing is used across Europe in patient management, but not in a consistent manner. This is due to differences in the national approaches to treatment, treatment management and reimbursement, as well as availability of tests. National guidelines only exist in some countries. In addition, the laboratory quality assurance and quality control standards are not applied uniformly. The EuroGuidelines Group was established to formulate clinical as well as laboratory guidelines for the use of HIV-1 drug resistance testing that are specific for the European setting. The group is comprised of academic clinicians and virologists, scientist from the industry and representatives of the patient community. The panel of experts will review these guidelines and update them on a yearly basis as new scientific evidence becomes available.

Abstract: Federally funded research involving inmates in US correctional facilities requires the approval of the Office for Protection from Research Risks (now called the Office for Human Research Protections [OHRP] and located in the Office of the Secretary of the Department of Health and Human Services). Trials that are carried out by pharmaceutical companies (not federally funded) fall under the jurisdiction of the FDA. This article reviews OHRP and FDA guidelines relevant to the conduct of HIV/AIDS clinical trials in correctional settings.

Abstract: OBJECTIVE: To update the recommendations for antiretroviral therapy (ART) in adult HIV-infected persons according to the new scientific advances and the existence of new antiretroviral drugs in the last two years. METHODS: The ART recommendations have been condensed by a panel of experts from the Spanish AIDS Study Group (Grupo de Estudio de Sida-GESIDA) of the Spanish Infectious Diseases and Clinical Microbiology Society (SEIMC) and from the Clinical Advisory Panel (CAP) of the Secretariat of the Spanish National Plan on AIDS (SPNS) of the Ministry of Health. Three levels of evidence have been established depending if the data came from randomized and controlled studies, from cohort or case-control studies or from descriptive studies and expert opinions, for that purpose we have reviewed the advanced in HIV pathophysiology and results of efficacy (clinical, virologic and immunologic) and security (toxicity) from clinical trials involving ART lasting at least 12 months, from cohort studies and pharmacokinetic and security data of antoiretrovírico drugs, presented in international conferences or published in biomedical journals in the last two years. In each situation we have established either to recommend or to consider or not recommend ART. RESULTS: Nowadays, ART consistent of at least three drugs constitutes the election therapy for chronic HIV infection, since it delays clinical progression, increases significantly the survival and diminishes hospital admissions and associated costs. The decision to start ART must be based upon three elements: presence or absence of symptoms, plasma vírica load and CD4+ cells counts. Thus, in asymptomatic cases with a high CD4+ cells count (> 500/microliter) and low vírica load (< 10,000 copies/ml by branched DNA bDNA or < 20,000 copies/ml by reverse-transcription polymerase chain reaction [RT-PCR] or nucleic acid sequence based amplification [NASBA]) we recommend to delay ART. In symptomatic patients we recommend to start it, and in asymptomatic patients, we could recommend or consider ART initiation depending on the risk of progression, established by the vírica load and the CD4+ cells count. In any case, if therapy is started, the objective must be to reach an indetectable vírica load (< 50 copies/ml). The adherence to ART plays a key role for its initial moment and for the duration of the antiviral response. ART can achieve a restoration of cellular immunity inb the advanced patients. There are few therapeutic options in failing patients due to cross-resistance. Resistance studies can be useful in this setting. The toxicity (lypodistrophy) is a new and limiting factor of ART which requires to look for new therapeutic options. ART criteria for acute infection, pregnancy, post-exposure prophylaxis and when to use resistance testing are discussed. CONCLUSIONS: In this moment, there is a more conservative attitude towards starting ART than in previous recommendations in which a virus eradication was considered. On the other hand, the high number of disposable drugs, the more sensitive monitorization methods (plasma vírica load) and the possibility of performing resistance studies make therapeutic strategies more dynamic and individualized for each patient and situation. In any case, it is mandatory to ensure a perfect adherence to ART from the patients.

Abstract: Dyslipidemia is a prevalent condition that affects patients infected with human immunodeficiency virus (HIV) who are receiving antiretroviral therapy. These preliminary recommendations summarize the current understanding in this area and propose guidelines for management. Existing guidelines for the management of dyslipidemia in the general population formed the general basis for our recommendations. Data on the prevalence and treatment of dyslipidemia of HIV-infected patients, implications of treatment-related dyslipidemia in other chronically ill populations, and pharmacokinetic profiles for the available hypolipidemic agents in non-HIV populations were considered. Although the implications of dyslipidemia in this population are not fully known, the frequency, type, and magnitude of lipid alterations in HIV-infected people are expected to result in increased cardiovascular morbidity. We propose that these patients undergo evaluation and treatment on the basis of existing guidelines for dyslipidemia, with the caveat that avoidance of interactions with antiretroviral agents is paramount.
