Living With HIV Decisions About Therapy

This was a daylong course in April at the Chelsea & Westminster Hospital, London designed for those living with HIV/AIDS. Professor Brian Gazzard gave a welcome and introduction to the day.
He spoke of plans to improve services for positive people using the hospital. Dr David Asboe, consultant physician, talked about disease progression and its measurement. He focused on the progression of HIV characterised by progressive loss in numbers and function of CD4 cells and the opportunistic infections associated with diminishing CD4 counts for example:

  • 400 - Herpes
  • 300 - Oral Candia & Tuberculosis (T B)
  • 200 - Pneumocystis Carinii Pneumonia (PCP) and Kaposi’s Sarcoma (KS)
  • 100 – Toxoplasmosis, Cytomegalovirus (CMV) Cryptosporidiosis, etc

Dr Asboe went on to discuss the clinical stages of HIV

  • Primary infection or seroconversion;
  • Asymptomactic stage;
  • Symptomatic stage and finally
  • AIDS.

He talked about factors that affected progression and why we measure it before looking at viral load measurement. The aim of measurement is to prevent disease progression.
Professor Brian Gazzard, Director of Clinical Research dealt with the optimum time to begin therapy followed by Dr Graeme Moyle who looked at treatment options. The final speaker before lunch was Dr Anton Pozniak casting an eye on future antiretrovirals. His best bet was that of taking your pills all the time and suggested that future treatments need to be more user friendly. He outlined some of the new drugs in trials like once a day protease inhibitors and a new class of drugs that don’t get into cells (extra cellular) like the fusion inhibitor T20.

Dr Pozniak addressed the question of stopping treatment by pointing out that the current evidence indicates that if you started treatment with a low CD4 count, you will return to that point quickly when you stop. It will also take a long time to get back up again. He believed it was better to stay on treatment than stopping. He pointed out that it isn’t the viral load that kills you, but not having a strong enough immune system to prevent opportunistic infections. Any rise in CD4 count helps you survive. The benefits of Interlukin 2 were mentioned.

After a sumptuous lunch in the Atrium, Juliet Allom, Clinical Nurse Specialist, talked about long and short term adherence, producing a graph of statistics presented at the 1999 Chicago conference of the relationship between adherence and virological control. She highlighted the following ways that you patients can help themselves

  • Prepare well (Information and advice, consider risks/benefits and lifestyle impact, take your time)
  • Establish a regular and ongoing support network.
  • Use the Multi-disciplinary team and voluntary sector Keep up to date
  • Use practical memory aids
  • Be honest with your doctor
  • Try to attend your regular, booked appointments

She mentioned the following as potential barriers to adherence: Inadequate patient/professional communication

  • Unresolved patient concerns such as fear of side effects – especially visible ones or anxiousness about the social stigma of taking medicines
  • Health Care Professional related issues such as clinicians believing that adherence is the patient’s problem

Dr Nick Theobald, Associate Specialist spoke about involving your GP in you HIV care and Bec Clarkson from the UK Coalition talked about their ‘Positive Futures’ project. Dr Mark Nelson dealt with the toxicity of therapy options noting that the success of antiviral therapy depended on the tolerability of drugs – a mixture of adherence, toxicity and potency. He outlined the toxic effects associated with specific drugs from AZT through to the latest nucleotide Tenofovir

A lively question and answer session ended the day in which the debate was led by the voices of people living with HIV/AIDS. A set of fact sheets from the Chelsea & Westminster Hospital can be found in the information/therapies room at the Hanley Centre.
