Causes and pathogenesis of AIDS in drug user and
homosexuals: In the USA, the total cases of AIDS in adults
was 573,800 as of
January 1, 1997 and about 90% of these
cases were male homosexuals and heterosexuals and homosexual drug users
(Fauci, et al., 1998).
The appearance of
AIDS in the USA and Europe in drug users and homosexuals in the late
1970’s and early 1980’s coincided with the synergistic actions of
several events. Briefly, these include the spread of illicit drug use,
especially smoking crack cocaine and heroin in 1970’s, the approval of
glucocorticoids aerosol by the US FDA in 1976, the wide use of
the glucocorticoid inhalers to treat chronic respiratory
illnesses resulting from inhaling cocaine and heroin, the
wide use of alkyl nitrites by homosexuals to facilitate anal sex in 1970’s,
and the wide use of corticosteroids to treat chronic gastrointestinal tract
illness in homosexuals. Furthermore, the approval of
antiviral drugs (AZT and protease inhibitors) and the steroids by
the U.S. FDA to treat patients with AIDS and asymptomatic patients
infected with HIV has exacerbated the problem (Al-Bayati, 1999).
The
HIV-hypothesis states that HIV causes AIDS by killing the CD4+ T cells
directly or indirectly (Fauci, et al., 1998). It
appears that there is no
scientific evidence to show that HIV can kill infected T4 cells (CD4+ T
cells) in
vitro or in vivo. In addition, the
abnormalities in the immune system of patients with AIDS
are not restricted to the reduction of
T4 cells as
predicted by the HIV-hypothesis. Hoxie et al. (1985) observed no evidence of death in T cells
infected with HIV in tissue culture. These cells continued to produce
virus particles for more than four months after inoculation with the
virus. Many reports describe the changes in the lymph nodes of patients
infected with HIV and these changes range from extensive cellular
hyperplasia of T and B lymphocytes and the supporting stroma to severe
atrophy of the glands. Changes in
the lymph nodes of 505 HIV infected patients who were asymptomatic or
had AIDS demonstrate three distinct stages. These are hyperplasia (245
patients), atrophy (117 patients), and mixed stage (172 patients) (Al-Bayati,
1999). The presence of hyperplasia in the infected lymph nodes
contradicts the HIV-hypothesis which states HIV destroys infected T
cells (Gallo, 1987; Fauci
et al., 1998)
Further
elucidation is provided by the proponents
of the HIV-hypothesis. Muro-Cacho,
Pantaleo, and, Fauci (1995)
examined 29 HIV+ lymph nodes and found twelve of these lymph nodes with
follicular hyperplasia and extensive germinal centers, five with
follicular hyperplasia mixed with follicular involution, twelve lymph
nodes with a mixture of follicular involution and lymphocyte depletion,
and five lymph nodes with lymphocyte depletion. They stated that
“apoptosis was not restricted only to CD4+ T cells; both B
cells and CD8+ T cells were found to undergo apoptosis. Taken together,
these results indicate that the increased intensity of the apoptotic
phenomenon in HIV infection is caused by the general state of immune
activation, and is independent of the progression of HIV activities and
the levels of viral load”. HIV
provirus was also found in CD4+ T cells, CD8+ T cells, and B cells
lymphocytes in the lymph nodes of HIV infected patients and its ability
to infect cells is not restricted to cells that have
CD4 receptor as predicted by the HIV-hypothesis (Al-Bayati,
1999).
The
changes in the lymph nodes described above are not unique to HIV
infected individuals but also were described in HIV-negative patients in
risk groups. The lymph nodes from
215 HIV-negative homosexual and drug users men showed hyperplasia and
atrophy and 15 lymph nodes showed Kaposi’s sarcoma and lymphoma. These
changes are AIDS-indicator diseases based on the CDC’s criteria, yet
the subjects were HIV-negative (Al-Bayati,
1999).
In
addition to the information presented above that demonstrate the
invalidity of the HIV-hypothesis, the rate of T cells infection by HIV,
and the rate of the thymus and the lymphoid tissue regeneration also
conflict with the HIV-hypothesis.

cannot kill enough t-cells
