What the ‘ARV defendants’ don’t want you to know about ARVs – part 3

ARVs have serious side effects including damage to the immune system

ARVs are toxic to all cells in the body. Those organs that have a high rate of cell proliferation (multiplication) are particularly affected by this toxicity.

ARVs are toxic to the bone marrow and blood-cell system and can cause anaemia (loss of red blood cells) and leukopenia (loss of white blood cells).

Certain ARVs block DNA synthesis in the cells of the body. However, these drugs cannot discriminate between the replicating virus and the rapidly dividing cells – such as those of the bone marrow – that are essential to keep the human body alive and in optimum health.

The organ system with the highest cell proliferation (multiplication) is the bone marrow, the production site of red and white blood cells. An impaired production/function of red blood cells leads to anaemia whereas an impaired production/function of white blood cells leads to an impairment of the immune system (drug-induced immune deficiency). The toxicity of ARVs on the bone marrow and blood-cell system and the known side effects of anaemia (loss of red blood cells) or leukopenia (loss of white blood cells) is known to the manufacturers of ARV drugs and is even part of the mandatory ARV product information. (See: Richman et al., New England Journal of Medicine (1987); 317: 192-197Costello et al., Journal of Clinical Pathology (1988); 41: 711-715Moore et al., Arch Intern Med (1991); 151: 981-986; and Dainiak et al., British Journal of Haematology (1988); 69: 299-304).

Although the doses of NRTIs (nucleoside reverse transcriptase inhibitors) have been lowered in the triple drug combination cocktails such as HAART, the toxicity is still evident as documented by the reports of thrombocytopenia and anaemia in the following studies: Carbonara S et al J Infect (2001) 42 (4): 251-256; and Mocroft et al., AIDS (1999); 13: 943-950.

Additionally, both NRTIs and non-nucleoside reverse transcriptase inhibitors (NNRTIs) contained in triple drug cocktails (e.g. HAART) are hepatotoxic, i.e. cause damage to the liver (Abrescia et al., Current Pharmaceutical Design (2005); 11: 3697-3710).

Further, NRTIs in HAART have been linked to mitochondrial toxicity (Fleischer R et al Clin Infect Dis (2004) 38(4): e79-80) and the protease inhibitors in HAART have been associated with a lipodystrophy syndrome, characterised by dyslipidemia, i.e. a severe impairment of the metabolism and storage of fats in the body (Carr et al., Lancet (2001); 357: 1412-1414).

Many ARVs also have other serious adverse side-effects. There are a number of metabolic complications associated with the use of some ARVs, including derangement in glucose and lipid metabolism, bone metabolism and lactic acidaemia (sustained accumulation of lactic acid in the blood), which have been documented in industrialised countries.

Some relevant studies pertaining to the damaging prenatal/perinatal effects of AZT are the following:

Blanche et al (1999) Persistent mitochondrial dysfunction and perinatal exposure to antiretroviral nucleoside analogues. Lancet 354: 1084-9.

Gerschenson M et al (2000) Fetal mitochondrial heart and skeletal muscle damage in Erythrocebus patas monkeys exposed in utero to 3’-azido-3’-deoxythymidine. AIDS Res Hum Retroviruses 16 (7): 635-44.

De Souza RS (2000) Effect of prenatal zidovudine on disease progression in perinatally HIV-1-infected infants. J AIDS 24 (2): 154-61

Kuhn L et al (2001) Disease progression and early viral dynamics in human immunodeficiency virus-infected children exposed to zidovudine during prenatal and perinatal periods. J. Infect Dis. 183 (10): 1540-2.

 

Both nucleoside reverse transcriptase inhibitors (NRTIs) and non-nucleoside reverse transcriptase inhibitors (NNRTIs) contained in triple drug cocktails are hepatotoxic, i.e. cause damage to the liver.
