aids treatment update july 2006 Why HIV-positive people need special consideration when it comes to vaccinations, by Edwin J Bernard After more than a year in the making, themost comprehensive immunisationguidelines ever produced for HIV-positiveadults are now available to download foran extended consultation period from theBritish HIV Association website. Theywill be revised based on feedback receivedby mid-September, and the final guidelineswill then be published in HIV Medicine. Compared with our HIV-negative counterparts, HIV-positive people may have an increased risk of infection, or experience more severe disease, following exposure to vaccine-preventable diseases.
The guidelines cover in detail how the risk of acquiring more than twenty infectious diseases - from anthrax to varicella zoster - can be substantially reduced in HIV-positive individuals via vaccination, some prior to, others after, exposure. In addition, the guidelines address the use of passive immunisation after exposure to infectious diseases such as measles or chicken pox.
The writing committee - which included virologists, microbiologists, infectious disease and HIV physicians, public health specialists, and epidemiologists - was headed by Dr Anna Maria Geretti, consultant virologist at London's Royal Free Hospital.
Here, she explains why the guidelines took so long to produce, provides an overview of the most important - and controversial - issues, and discusses some practical considerations, including who will pay for and provide the various vaccines.

abacavir in one pill - should only be considered as a Now, new research from France has found that PAH is no less starting regimen in very occasional circumstances, for common today than it was ten years ago. Last year, 7,648 HIV example when TB medicine is also needed (since there are patients from 14 centres across France were screened for PAH. Of interactions with most other anti-HIV drug combinations) 739 found to be suffering from breathlessness - the most common or when one pill once a day will make a significant early sign of PAH - thirty-five were found to have PAH after further difference to treatment adherence. This is because several investigation: an incidence rate of almost one-in-200.
studies have found that triple NRTIs are not as potent as combining two NRTIs with another class of drugs.
Lead author Dr Olivier Sitbon told the American Thoracic Society International Conference, held in San Diego in May, that doctors The Italian study wanted to see if patients who took should have a low threshold for suspecting PAH if their patient abacavir as a third drug, and who had initially achieved an undetectable viral load, had an increased risk of experiencing subsequent virological failure compared to It is currently unknown why HIV can cause the pulmonary arteries individuals taking efavirenz-based therapy. They observed to become thickened and narrowed, leading to PAH. In addition, 744 patients who were starting anti-HIV therapy for the PAH is seen in all groups of people with HIV infection, irrespective first time and found that those who took abacavir as their of the cause of infection or CD4 count. It is also a much more third drug had an 85% greater risk of rebound than those serious disease in HIV infection, and according to a Spanish study who received efavirenz.

LGV continues to spread amongst HIV-positive gay men Almost 350 cases of the sexually transmitted infection (STI) lymphogranuloma venereum (LGV) - a form of chlamydia usually affecting the rectum - have now been diagnosed in the United Kingdom. Nearly all of the cases involved gay men, more than 75% of whom were HIV-positive. Coinfection with other sexually transmitted infections is being seen at the same time: one-in-four had another STI, and hepatitis C virus coinfection was seen in one-in-ten.
Epidemiological evidence suggests that LGV is transmitted via unprotected anal sex and fisting, which may also be the way the hepatitis C is being transmitted sexually; again this is primarily affecting HIV-positive gay men.
Men who have sex with multiple partners at sex parties and sex clubs appear to be most likely to be diagnosed with LGV; 71% of the men diagnosed so far reported this risk factor. LGV has now been seen in all parts of the UK, although most of the cases are being diagnosed in London and Brighton: the Kobler Centre at the Chelsea and Westminster Hospital in London is reportedly diagnosing ten new cases of LGV infection a week.
LGV can cause very unpleasant symptoms, similar to other bowel disorders, and may not be correctly diagnosed at first. In the current outbreak, the commonest symptom has been proctitis - pain and inflammation in the anus and rectum. In some cases this has been accompanied by swollen glands in the groin, and often by a discharge of mucus from the rectum (which can be bloody), and constipation.
Condoms and latex gloves are very effective at preventing the transmission of STIs, including LGV, and, once correctly diagnosed, the infection can be cured using a 21-day course of the oral antibiotic doxycycline.
Anti-HIV therapy adds thirteen years to post-AIDS survival American researchers have calculated that today's highly effective anti-HIV treatments have added 160 months (thirteen years andfour months) to a person's life expectancy once they have been diagnosed with AIDS.
Using a computer model to determine the effect six periods of anti-HIV treatment had on the survival of people with HIV after an AIDSdiagnosis, they found that post-AIDS survival increased from 19 months prior to 1996 to 179 months - almost fifteen years - after 2003.
"This survival benefit greatly exceeds that achieved for patients with many other chronic diseases in the United States," they say.

background therapy regimen of 2 aids treatment update july 2006 primary care at hiv clinics are HIV clinics providing GP services? wonders Edwin J Bernard In our lead article, Better Practice, it was argued that the integration of GPsinto caring for HIV-positive people is inevitable. NAM has been hearing froma lot of concerned HIV-positive people regarding this move. Since each HIVclinic has its own policies we thought we'd try and find out ourselves what ishappening. It hasn't been easy. In May, we emailed a snapshot survey to seventeen HIV clinics across the country. We received six responses at press time - four from clinics in London, one from Manchester and one from Edinburgh.
Although their responses may not reflect what is happening at your HIV clinic, the different policies and attitudes make for Do you have a policy regarding your patients having GPs? Central Middlesex Hospital, London: We encourage our patients to see aGP, or get registered with one.
Ealing Hospital, London: We try to provide a "holistic service" andtherefore end up treating many non-HIV-related conditions. This isparticularly so for the 40% of our patients who either don't have a GP ordo not allow us to contact their GP. We will resist any policy to changethis.
Queen Mary's Hospital, London: We have an ethos rather than a policy.
We encourage patients to have a GP and see their GP for non HIV-relatedcare.
further information Mortimer Market Centre, London: Our policy is to advise all patients to To find out more about the Patient have a GP for all the usual reasons. We keep to General Medical Council Advice and Liaison Service (PALS), [GMC] guidance on confidentiality and communication.
which provides information on the NHS North Manchester General Hospital: We have no policy as such, but we do and health related matters and encourage all patients to register with a GP and endeavour to find them confidential assistance in resolving one if they are not registered.
problems and concerns quickly, contact your local PCT or NHS Direct on Western General Hospital, Edinburgh: We have no written policy. We do not see patients for non HIV-related care outside their routine HIVappointments. If patients pitch up without an appointment, they are For more on the GMC's confidentiality directed to acute receiving; if their problem is HIV related, they will be aids treatment update july 2006 Do you have a policy regarding providing prescriptions for drugs that are not antiretrovirals, but may berequired due to HIV infection (e.g. lipid-lowering drugs, diabetes meds, antidepressants etc.)? Central Middlesex Hospital: Yes. We are generally happy to prescribe these, except now that home delivery has started, prescribing these drugs is more difficult. We will have to ask GPs to do more in the future.
Ealing Hospital: We prescribe everything on our hospital formulary through our HIV pharmacy annex. Prescriptions are, therefore, free. This includes all the drugs you've listed as well as vaccines, malaria prophylaxis, etc.
Queen Mary's Hospital: We encourage people to be prescribed medication by the service which manages them. For example, we don't manage their diabetes or increased lipids, so wouldn't prescribe those medicines, but we have policies on when to refer on, where problems are related to HIV.
Mortimer Market Centre: Our clinic guide advises that patients should be encouraged to consult their GP for non HIV-relatedissues. If there is no GP or we have no consent for GP communication then we will prescribe for certain non HIV-relatedproblems, though we advise patients that the GP may be the most appropriate person to be doing the prescribing.
North Manchester General Hospital: As long as their antiretrovirals are also on the prescriptions, or the patient is known to beon antiretrovirals, then these kind of drugs are issued. We try to persuade patients to get GPs and eventually for them to takeover the care of and prescribing for non HIV-related conditions - but with backup phone numbers for discussions aboutinteractions etc.
Western General Hospital: We used to provide these meds via our hospital pharmacy but our pharmacy dispensing service isstretched and cannot cope. At our discretion, however, we would squeeze a non HIV prescription in, if the patient cannot get totheir GP.
Do you maintain a referral list ofHIV-friendly GPs, HIV-educated How are you helping patients who cannot access a local GPs, or GPs providing a locally GP they trust and/or do not wish to disclose their HIV enhanced service in your area? status to their GP? Central Middlesex Hospital: We used Central Middlesex Hospital: We would prescribe for them, but to, but not now really. There are no our community workers will help them find GPs if possible.
local GPs who we think are specificallyHIV-unfriendly.
Ealing Hospital: We encourage patients to register and use a GP. We do our best to make up for the lack of a GP if Ealing Hospital: We know of GPs in they do not wish to have or use a GP.
the area who we think are good,knowledgeable and non-judgemental.
Queen Mary's Hospital: If patients don't wish to disclose Many years ago we ran a project with their status to a GP, we discuss this with them and challenge Hammersmith Hospital to help care their beliefs regarding confidentiality. Where there is a genuine for people with HIV, and thus had a concern - for example, their neighbour works at the GP's practice "special" liaison with some GP's in - we would help them find a different GP, and occasionally people have changed their GP to enable them to discuss their HIV.
Queen Mary's Hospital: We have a Mortimer Market Centre: If patients can't find a suitable GP then we community clinical nurse specialist to tell them to contact the Patient Advice and Liaison Service (PALS) assist with this. She knows which GPs or NHS Direct and we provide the telephone number. We utilise the have other HIV-positive patients, which NHS website to give information on their nearest GP surgery. If they reassures people who have concerns do not trust their GP then we discuss the reasons behind this and at about confidentiality which are more the end of the day must respect the patient's wish for confidentiality to do with their fear than reality.
as per GMC guidance.as long as the patient is making an informeddecision, then we respect this.
Mortimer Market Centre: No.
North Manchester General Hospital: We take over the prescribing North Manchester General Hospital: and, where possible, try and find the patient a ‘good' GP in their area.
Western General Hospital: Almost all of our patients have a GP who Western General Hospital: Our would provide primary care. If there is a problem, they are helped to Edinburgh GPs are usually very helpful choose another GP or use A&E services.
and we very rarely have problems. Weare lucky.
