Percutaneous endoscopic gastrostomy feeding in AIDS

Novel Adherence Interventions in Perinatally Acquired HIV: PEG Insertion and Pill Glide

BACKGROUND AND OBJECTIVES

Children, adolescents and young adults (CAYA) with perinatally acquired human immunodeficiency virus (PaHIV) need lifelong antiretroviral therapy (ART) to suppress viral load (VL), maintain health and prevent onward transmission. Many struggle with adherence despite multidisciplinary input. We assessed ART adherence outcomes following two novel interventions: percutaneous endoscopic gastrostomy (PEG) and Pill Glide^®, a fruit-flavoured lubricant spray aiding tablet swallowing.

METHODS

Retrospective cohort analysis by database and case-note review of PaHIV CAYA aged < 25 years receiving PEG or Pill Glide^® between 1995 and 2017 at a single tertiary centre.

RESULTS

Nineteen PEGs were inserted in 15 CAYA at a median age of 17 (IQR 6-22) years, median CD4 count 40 cells/µL (IQR 10-220). A viral load (VL) < 50 copies/mL was achieved in 93% with PEG ART. At last follow-up all were alive, median age 23 years (IQR 22-28). Nine had PEG removed, after a median of 3.3 years (range 0.5-6.8), with a current VL < 50 copies/mL, median CD4 count 940 cells/µL (IQR 261-1353) sustained post PEG removal median was 5.4 years (range 1.5-17.8) previously. From 2017 seven CAYA received Pill Glide^®, median age 10 years (IQR 7-14), median CD4 count 898 cells/µL (range 148-1943), 6/7 with a suppressed VL. All reported increased ease in tablet swallowing and transitioned successfully from crushed tablets/liquids to tablets. At follow-up, all patients had a suppressed VL.

CONCLUSIONS

Whilst PEG insertion markedly improved rates of viral suppression in CAYA struggling with ART adherence, the use of novel less invasive aids such as Pill Glide^® requires further exploration.

Bypassing non-adherence via PEG in a critically ill HIV-1-infected patient

This case study describes a 44-year-old, chronically non-adherent, HIV-infected male with relapsing, life threatening toxoplasmic encephalitis (TE) and other recurring opportunistic infections. Non-adherence resulted in critical illness, suppressed CD4 lymphocyte count and elevated viral load. In order to bypass the patient's complete psychological aversion to taking medication, and after exhausting various psychological interventions, a percutaneous endoscopic gastronomy (PEG) tube was inserted for delivery of indispensable medication. During the 15-month follow-up the patient was adherent, exhibiting a consistently undetectable viral load, high CD4 count and a remission of the opportunistic infections. This is an interesting case study demonstrating life-saving and long-term benefit of PEG in an exceptional setting, which has implications for future research and treatment of non-adherent HIV-infected patients.

ESPEN Guidelines on Enteral Nutrition: Wasting in HIV and other chronic infectious diseases

Undernutrition (wasting) is still frequent in patients infected with the human immunodeficiency virus (HIV), despite recent decreases in the prevalence of undernutrition in western countries (as opposed to developing countries) due to the use of highly active antiretroviral treatment. Undernutrition has been shown to have a negative prognostic effect independently of immunodeficiency and viral load. These guidelines are intended to give evidence-based recommendations for the use of enteral nutrition (EN) by means of oral nutritional supplements (ONS) and tube feeding (TF) in HIV-infected patients. They were developed by an interdisciplinary expert group in accordance with officially accepted standards and is based on all relevant publications since 1985. Nutritional therapy is indicated when significant weight loss (>5% in 3 months) or a significant loss of body cell mass (>5% in 3 months) has occurred, and should be considered when the body mass index (BMI) is <18.5 kg/m(2). If normal food intake including nutritional counselling and optimal use of ONS cannot achieve an adequate nutrient intake, TF with standard formulae is indicated. Due to conflicting results from studies investigating the impact of immune-modulating formulae, these are not generally recommended. The results obtained in HIV patients may be extrapolated to other chronic infectious diseases, in the absence of available data.

[Endoscopic gastrostomy in patients with complicated heart diseases]

Complicated cardiologic patients with brain ischemia and heart failure need long term enteral nutrition. Long term nasoenteral tube feeding may cause complications that could be avoided with percutaneous endoscopic gastrostomy. The aim of this study was to evaluate the indications for percutaneous endoscopic gastrostomy and its main complications. Twelve patients were submitted to percutaneous endoscopic gastrostomy (eight male) with main age of 62.42 +/- 22.10 years old. Brain ischemia was the main indication of percutaneous endoscopic gastrostomy and occurred after 35.58 +/- 26.79 days, after initiated enteral nutrition. There were no complications during procedure. On late post operatory period there were local infection in one cases, treated with local care. In conclusion, percutaneous endoscopic gastrostomy is a secure technique with low incidence of complications and its indication should be earlier.
