Living With HIV

Dr V Harindra FRCP, FRCP(Glasg) Consultant Physician St. Mary’s Hospital Portsmouth. UK


THE FIRST YEARS • Unexpectedly Diagnosed January 2006 at age 38 • Initial Reactions; – “Is my partner safe?” – “You Stupid Idiot! You have friends who died of AIDS. How could you let this happen to you?” – “Who did I get it from?” – “Who do I tell? Who needs to know?” – “How many years will I live for?”

• Started ARV Therapy January 2007 – Drug switch within 1st 6 months due to side effects.

• Relationship ended • Read every bit of HIV related information I could get my hands on • Slowly came to terms with diagnosis


7 YEARS ON • Generally positive outlook • 100% adherent having maintained undetectable viral load and CD4 averaging 800 • Longevity expectations? – Hopefully I will live ‘near-normal’ lifespan but I’m not banking on it! – Nevertheless, I’m making long-term plans

• It doesn’t define who I am – But it has an unavoidable impact on my daily life

• Disclosure? – I’ve mostly disclosed to friends but not to family (my parents would only worry so what’s the point?) – I’ve disclosed to work, mainly for practical reasons due to inability to travel to certain destinations


DOWNSIDES • Rejection and Stigma – Surprisingly from the gay community

• General increase in anxiety overall – Health • Toxicity of drugs • Body fat changes • reduced energy levels • Co morbidities (Meniere’s disease) • Neuro-cognitive impairment? – Financial • what if I need to stop working? • I need to pay off my mortgage early • I’m maxing-out my pension AVCs • Practical issues – Medical appointments – Adherence – Restrictions in travel (avoidance of travel to certain countries)


HOW DID I COME TO TERMS WITH DIAGNOSIS? • I’m lucky! – Thanks to medical advances, I’m alive and have a ‘near-normal’ life expectancy!

• Re-evaluation of what’s important in life • The support of a fantastic partner – (who is HIV negative)

• The support of friends • The support of a brilliant HIV healthcare team


THE FUTURE? • Monotherapy? – Early indications are that this is a viable approach? – Minimise toxicity and side effects

• Eradication of HIV? – Unlikely in my lifetime

• Maintain optimum health – Lifestyle choices (e.g. diet, exercise) – Stop smoking!

• Continue Planning for the Future


Living With HIV • HIV infection has become a chronic disease with a good prognosis provided – Treatment is started sufficiently early in the course of the disease – The patient is able to maintain lifelong adherence to ART

• Life expectancy in the general population varies by – Age, sex, and race – Substantial differences between low and high income countries

• The pattern of the HIV epidemic varies by country • The risk of death in successfully treated patients is similar to that of people with unhealthy lifestyles or other chronic conditions such as diabetes

HIV & Cardiovascular Disease ‘HIV’ risk factors ?

‘Standard’ risk factors - Smoking - Family history - Hypertension - Diabetes - Obesity - Male and age - Hyperlipidaemia

Vascular disease

- Increased prevalence of standard risk factors - HIV - HAART (PI > others?) - HAART-related Hyperlipidaemia [+/- Insulin resistance, metabolic consequences of fat redistribution, hypertension, inflammatory process]


HIV & Cardiovascular Disease • The risk of CVD is greater in PLHIV – Meta-analysis of literature: • RR 1.61 for CVD in untreated HIV pts vs uninfected controls; • RR 2.0 for CVD in treated HIV pts vs controls

• CVD is more likely to be acquired with lower CD4 counts – CD4 count < 350 cells/μL – CD4 count > 350 cells/μL

1.58 (95% CI 1.09, 2.30) 1.28 (95% CI 0.81, 2.02)

• Use of PI and non-PI-based ARTs was associated with CVD – PI 6.22 (95% CI 3.13, 12.39) – Non – PI 3.18 (95% CI 1.99, 5.09) – Estimated combined RR of MI for PI- vs. non-PI-based ART to be 1.79 (95% CI 1.05, 1.72)

Risk Factors for Kidney Disease • • • • • •

Diabetes Mellitus Hypertension Smoking BMI Age Race (African-Caribbean or south Asian origin)

• CKD is present in 15-18% of HIV+

patients – eGFR <60

2-6%

– Proteinuria

10-14%

Proteinuria is defined as: • Urine albumin:creatinine ratio >30mg/mmol or • albumin concentration >200mg/l or • Urine protein:creatinine ratios >45 mg/mmol


HIV-Related Renal Disease • HIV-associated nephropathy (HIVAN), -- focal segmental glomerulosclerosis presenting with nephrotic syndrome and progressive renal insufficiency • One third of HIV-infected patients with renal disease have glomerular diseases other than HIVAN – – – – –

Membranoproliferative glomerulonephritis Minimal change disease Membranous glomerulopathy amyloidosis, immune-complex glomerulonephritis IgA nephropathy

• Antiretroviral therapy is associated with less rapid progression of HIVAN

Available at: http://www.usrds.org/adr.htm


Cumulative ARV Exposure and Risk of CKD • Cumulative exposure to TDF, ATV, LPV/RTV, or IDV each associated with increased risk of CKD • Renal toxicities are rare with NNRTIs, entry inhibitors, and integrase inhibitors • Risk of CKD after stopping TDF remained elevated for 1 yr – Within 12 mos: IRR 4.05 (2.51-6.53) – After 12 mos: IRR 1.12 (0.63-1.99)

• Risk of CKD after stopping ATV or LPV/RTV similar to pts never exposed

Liver Related Disease • Alcohol abuse • Infectious hepatitis • Drug-induced liver disease • Non-Alcoholic fatty liver disease

• A significant increase in the death rates from LRD in PLHIV • The risk of liver-related toxicities is considerably higher in patients coinfected with HBV and/or HCV • HAART reduced the death rate from LRD by increasing the CD4 cell count

• Death rates due to LRD might increase with longer exposure to HAART – Progression of liver disease due to hepatitis B or C over time – Direct liver toxicity of antiretrovirals – some other factor - ? Fatty liver


Mental Health in HIV • Most at risk for HIV infection often have high rates of mental illness • Most common mental disorders seen in people with HIV infection are – Mood disorders – Anxiety disorders, including post-traumatic stress disorder (PTSD); – Alcohol or other substance use disorders

• One third of patients with HIV infection suffer from major depression – Increased morbidity and mortality from HIV infection

• Direct effect of HIV on the brain can cause cognitive impairment – HIV-associated dementia – Milder or asymptomatic cognitive impairment can be more difficult to assess

• HAART reduces the rate of development of HIV dementia and can reverse cognitive deficits – Milder forms of cognitive impairment appear to be more refractory to treatment


Natural History of Untreated HIV Infection in Older vs Younger Patients • The natural history of HIV infection is generally unfavourable for older patients • Following acute infection, average HIV-1 RNA plasma titers are 0.4-0.5 log10 copies/mL higher in older (aged > 40 years) vs younger (16-20 years) patients • CD4+ cell counts are 40 cells/mm3 lower in individuals aged 40 years or older compared with individuals younger than 40 years of age (P < .01) • Older persons have faster rates of CD4+ cell count decline and more rapid progression to AIDS and death • Every 10 years of increased age, there was a 32% increased risk of developing AIDS and a 47% greater risk of death (independent of the CD4+ cell count and HIV-1 RNA level)
