The researcher David Zagury who has conducted a series of AIDS vaccine trials over
the last few years has been cleared of charges that he acted without the approval
of the French ethics committee for his research in France; Nature
350: 546; Science
252: 203; BMJ
302: 930. Because of criticism of his research ethics the US Government support
for the trials in African countries had been suspended; JAMA
265: 2648-9. The NIH committee is still discussing the issue. Following the clearance
from French authorities, there were several deaths in treated patients reported.
The deaths occured last year, so that a new enquiry is being launched; Science
252: 501-2, NS
(27 April 1991), 9. Two patients may have developed a fatal vaccinia infection after
receiving the vaccine which includes "inactivated" vaccinia. On another possible
therapeutic method, see M.Zeira et al., "Full-length CD4 electroinserted in the erythrocyte
membrane as a long-lived inhibitor of infection by HIV", PNAS
88: 4409-13.
A general comment on the ethical issues and political issues in the future AIDS research
(see p.53 in this issue), and vaccine trials is in NS
(27 April 1991), 5 & 25-9. An even more controversial experiment could be the innoculation
of AIDS patients with live HIV as a vaccine. The particular HIV is thought to be
a nonpathogenic form of the virus, so it may compete with the pathogenic form in
the patients; NS
(13 April 1991), 10. The results are mixed, but the reaction is even more mixed to the
ethicality of such trials! The results were published in Lancet only as a short letter,
saying the results could be obtained by writing to the journal or researchers; Lancet
377: 731.
The French Government has banned the AIDS vaccine trials of researcher David Zagury in France; Science 252: 1608; NS (22 June 1991), 18, Nature 352: 180. For a background see EEIN 1: 45. A comment on the NIH ethics report on this case is in NS (27 July 1991), 12; Nature 352: 269. The reason for the ban was questions about the safety of the recombinant vaccinia virus used. On the results of human testing of another putative AIDS vaccine see SA (Aug 1991), 14. Another putative vaccine has failed to be effective in preventing sexual transfer of HIV in monkeys; NS (6 July 1991), 24. Another approach, using soluble recombinant CD4 protein has protected chimps against HIV infection; R.H.R. Ward et al., "Prevention of HIV-1 IIIB infection in chimpanzees by CD4 immunoadhesin", Nature 352: 434-6; see also P. Putkonen et al., "Prevention of HIV-2 and SIVsm infection by passive immunisation in cynomolgous monkeys", Nature 352: 436-8; p.376-7; NS (3 Aug 1991), 15. A review on the prospects for a HIV vaccine is in FASEB J. 5: 2406-11.
There are many problems being encountered in the treatment and screening for AIDS,
which can be a model for future screening in general. The HIV epidemic is acting
as a catalyst for discussions about some ethics, in the same way that genetics can
do. In view of this and the importance because of the growing numbers involved, some of
the papers regarding AIDS will be mentioned, to keep us up-to-date in this area also.
A summary of the current state of HIV infection is normally found in the WHO publication,
World Health
.. A recent summary is in Science
252: 372-3. About 1 million people are suffering from AIDS, and about 8-10 million
infected, from WHO estimates. The cases are not well documented, so that the official
figures are less. On AIDS in Thailand see MJA
154: 282-4. On HIV testing in India see NS
(20 April 1991), 12. On HIV in children see Lancet
337: 1030; BMJ
302: 921-2; JAMA
265: 2652. They are trying voluntary programs to encourage brothels to use condoms.
Book reviews on the history of AIDS are in Science
252: 453, 985-6. Comments on the issues are in NEJM
324: 1498-1504.
A paper on HIV counseling is in Lancet
337: 950, see also BMJ
302: 801-2. A letter on the preferences of HIV-infected patients on aggressive or
palliative care was surveyed in the USA, see NEJM
324: 1140. 54% prefered palliative care, 29% prefered an aggressive approach even
if it would involve more pain. One social effect of HIV testing policy is in J. McKillip,
"The effect of mandatory premarital HIV testing on marriage: the case of Illinois", AJPH
81: 650-3. The laws in other US states are also mentioned, as is the marriage of
couples in neighbouring states to avoid the screening. The USA has reversed its earlier
decision to open up immigration for foreigners infected with HIV; NS
(8 June 1991), 14. This will be fought again, because it is discriminating and may even
discourage people from taking HIV tests. WHO has decided to withdraw support for
the Jan. 1992 AIDS conference in Boston.
Letters on HIV testing in pregnancy are in Lancet
337: 1218: 9. See also M.Grimm et al., "Prevalence of HIV infection in childbearing
women in the United States", JAMA
265: 1704-8, and JAMA
265: 1798-9 & 1805. On the mechanism of transfer, through the placenta, see NS
(1 June 1991), 20.
There is a special supplement to the May issue of the American J. Public Health
on the New York HIV seroprevalence project (c.70pp.). See also AJPH
81; 561-2. The results of anonymised HIV testing in Britain are in BMJ
302: 1229. On other comments on HIV testing see Nation's Health
(Feb 1991), 4; (March 1991), 1, 17, 24; and the HCR (March/April 1991), 7-11. For a general view
that physicians have an obligation to treat the sick, and the ethical arguments underlying
this see N.Daniels, "Duty to treat or right to refuse?", HCR
(March/April 1991), 36-46.
A case on the hospital testing for AIDS in employees in a US Court of Appeals found
that a hospital could dismiss a worker who refused to give blood for a HIV test;
AJLM
XVII: 181-3. A letter on hospital testing policies appears in JAMA
265: 1685. See a meeting description in the Nation's Health
(April 1991), 15. A commentary on the risk of contracting HIV infection in the course
of health care is in JAMA
265: 1872-3, see also JAMA
265: 2337-8; NEJM
324: 1504-8; and B.Gerbert et al. (1991) "Possible health care professional-to-patient
HIV transmission. Dentist's reactions to a Centers for Disease Control Report", JAMA
265: 1845-8. Most dentists thought that if dentists are infected with HIV they should
refrain from work. The results of a survey of HIV infection among orthopedic surgeons
is in JAMA
265: 2779-80, and for HIV in US army reserve health workers JAMA
265: 2826-30.
On scientific ethics. A paper S.Wain-Hobson et al., "LAV revisited: origins of the
early HIV-1 isolates from Institut Pasteur", Science
252: 961-5, describes the origin of the first HIV to be isolated. Gallo of the NIH
has finally admitted that the HIV that he isolated in 1984 really came from the Pasteur
Institute; NS
(8 June 1991),14; Nature
351: 267, 426-7; Science
252: 771. It has long been suspected. This means that more of the currently equally
shared patent should go to the Pasteur Institute. Gallo personally earns about US$100,000
annually from his share of the roylaties on HIV tests!
Possible trials of an AIDS vaccine in pregnant women in the USA are being considered,
but vaccine manufacturers are concerned about possible liability claims should any
fetus be harmed as a side-effect; BMJ
303: 665; NS
(31 Aug 1991), 11. There is also a trial underway to test whether AZT affects HIV transmission.
More on the Zagury AIDS vaccine trials in Rwanda is in Nature
353: 4; and the apparent confusion of the NIH about regulations on clinical trials
overseas; BMJ
303: 329-30. Meanwhile the efficacy of an AIDS vaccine trial that reportedly had
worked in macaque monkeys, is now under suspicion, so that prospective human trials
in the U.K. will be delayed; Nature
353: 287; NS
(21 Sept 1991), 14. On AIDS vaccines see JAMA
266: 763-4; BMJ
303: 872.
A summary of the conclusions of a U.K. MRC Working Party report on AIDS vaccine trials is reproduced in the BME (Nov 1991), 9-11. An international meeting on AIDS vaccine suggests that the first major trials by major organisations may be in 1995 or later; Science 254: 647, though the vaccine is still to be developed. There may still be earlier trials elsewhere, in Zaire, Uganda, Rwanda, Thailand and Brazil; BMJ 303: 1219-20. The ethical issues are still being examined, because of the variety of people's involved. See also Genetic Research 58: 177-8, for a book review; TIBTECH 9: 124-31, on CD4 antigen; Biotechnology 9: 779; MJA 155: 403-6; and on tougher FDA regulations for AIDS vaccines; Science 254: 1105; and see the section on AIDS later in this issue.
A review on the development of HIV vaccines is in Biotechnology 10: 24-9. It is written in a market orientated tone, and lists some of the current commercial research projects in pursuit of this goal, in addition to the patents. The Zagury case in France may be over and he has been exonerated by the French physician's licensing body of the charges made against him due to the treatment of patients with a putative AIDS vaccine; Science 255: 280. On a possible future AIDS drug Ro 24-7429 see Science 255 (1991), 1715.
AIDS
vaccine trials have begin in some high risk populations; Science
258 (1992), 1729; and in infants whose mothers are HIV-infected; Science
258 (1992), 1568-70. The debate on the choice of which vaccines should be tested
is in Biotechnology
10 (1992), 1521; Science
259: 752-3. Although infants can not give consent, a typical HIV-infected infant
will die at two years of age - the progress being much faster than in adults. Some
researchers believe that the old approach using live weakened virus as a vaccine
needs to be reexamined; Science
258 (1992), 1880-1.
A review of
malaria
transmission-blocking vaccines is in TIBTECH
10 (1992), 388-91. Adult immunisation with acellular
pertusis
vaccine is recommended following a placebo-controlled double-blind trial; JAMA
269: 53-6. A report about development of the hepatitis A vaccine is in MJA
157 (1992), 345. The organisation Rotary International has started funding efforts
to ensure that
polio
is erradicated from the world by the year 2005; JAMA
269: 15-6. A letter asking about the sustainibility of
universal
childhood vaccination is in Lancet
341: 58. This follows recent declines in vaccination rates in 13 African countries.
A review of childhood immunisation is in NEJM
327 (1992), 1794-1800. As reported previously (EEIN
3: 2), researchers are attempting to produce hepatitis vaccine in banana to be an
oral vaccine; Science
258: 1878.
A review of the laws in the USA regarding
tuberculosis
is L.O. Gostin, "Controlling the resurgent tuberculosis epidemic: A 50-state survey
of TB statutes and proposals for reform", JAMA
269: 255-61. A book review of interest to the treatment of TB patients in the past
is in JAMA
269: 531. B. Healy of the NIH has transferred a further US$12.5 million into TB
research this year; Science
259: 886. This follows reports calling for more funding, JAMA
269: 187-8, 91, 95; see also Science
259: 167. In some regions of the the UK also, notification rates for TB are rising,
BMJ
306: 221-2. BCG vaccination at age 13 years is debated in BMJ
306: 222-3.
A summary of a paper on the public
acceptability
of vaccination in Saudi Arabia, published in Ann Saudi Med.
, is in JAMA
268 (1992), 3422. High public support for the immunisation goals was observed.
In Zaire, providing transport to clinics would increase the rates; World Health
(Sept. 1992), 24. In the USA, Congress is attempting to simplify the booklets that
explain immunisation; JAMA
268 (1992), 3413. Inner city residents show low perception of a need; Clinical Pediatrics
32: 2-7. A Canadian study of the language that mothers prefer in vaccination brochures
is in CMAJ
147 (1992), 1013-7.
It is known that a child who catches measles from a family member is twice as likely
to die as one who catches measles from an unrelated person. This is because of the
MHC
antigens, and an extension of this idea may explain why so many people in the Americas
died as a result of introduced diseases; Science
258 (1992), 1739-40. People in South America have very closely related MHC antigens,
with much less diversity than in other parts of the world. Therefore a virus or
bacteria spreading from one to another host is already adapted to evading the immune
system of the new host. An editorial on the continual rise and fall of different diseases
in human history is in Lancet
341: 151-2. A review of viral genetic variation in hepatitis B is in Lancet
341: 349-53.
The US Immigration Department continues to list HIV infection as a disease which can
ban entry to the USA, despite assurances that it would be off the list. This has
meant the the 1992 AIDS conference will probably not be held in Boston; BMJ
302: 1360; Nature
351: 682. There are claims that the UK Government has a hidden HIV ban on immigration;
NS
(6 Jul), 17.
The latest results from the anonymised HIV testing in the UK are commented on in Lancet
337: 1572-3, and are reported in two papers; A.E. Ades et al., "Prevalence of maternal
HIV-1 infection in Thames Regions: results from anonymous unlinked neonatal testing",
Lancet
337: 1562-5; D.M. Tapin et al., "Prevalence of maternal HIV infection in Scotland
based on unlinked anonymous testing of newborn babies", Lancet
337: 1565-7. They tested for HIV antigens transmitted in utero from infected mothers.
The obstetricians were only aware of maternal HIV infection in 20% of the cases
where infants were positive for HIV. The prevalence of antiHIV-1 in newborn babies
at the beginning of 1991 in inner areas of London is 1 in 500. On the time of viral
transmission see A. Ehrnst et al., "HIV in pregnant women and their offspring: evidence
for a late transmission", Lancet
338: 203-7.
See D.E. Bloom & S. Glied, "Benefits and costs of HIV testing", Science
252: 1798-1804, for a look from the employers perspective. The results suggest that
it is not cost effective for most private companies to perform such tests. A letter
on the ethics of such research is in CMAJ
144: 1603-4. A paper on the treatment choices and ethics for infants at risk for
HIV is in JAMA
265: 2976-81. A letter on antenatal HIV testing is in BMJ
302: 1400.
A special issue of the FASEB J.
(Vol 5, No. 10, July 1991) includes about 110 pp. of articles on HIV and AIDS. On the
science of HIV infection see NS
(29 June 1991), 19. A summary of the 7th annual AIDS conference is in Science
252: 1779. See also Lancet
338: 86-7. The Journal of Pediatrics
has published a 42 pp. supplement entitled "Guidelines for the care of children and
adolescents with HIV infection", in the July issue. A series of articles are presented.
The difficulty of disclosing test results to patients in India is noted in NS
(3 Aug 1991), 10.
The case involving the transmission of HIV from the Florida dentist to 3 of his patients
is commented on in JAMA
266: 23-4. An editorial on surgeons at the risk of HIV contamination during operations
is in JRSM
84: 327-8. On possible compulsory HIV testing for US health workers see NS
(27 Jul), 12; and on voluntary guidelines see BMJ
303: 205-6. The AMA rejects such testing; BMJ
303: 77. See also J.L. Gerberding, "Reducing occupational risk of HIV infection",
Hospital Practice
(15 June 1991), 103-8, which reports on the policy at San Francisco General Hospital for
isolation of body substances.
Important is the use of screening for HIV infection in blood used for blood donation.
A paper; M.P. Busch et al., "Evaluation of screened blood donations for HIV-1 infection
by culture and DNA amplification of pooled cells", NEJM
325: 1-5; found that the probability that a screened donor will be positive for HIV-1
is about 1 in 61, 171! The city used was San Francisco. A French case where HIV-infected
blood was mixed for use in transfusion is commented on in NS
(15 June 1991), 14; BMJ
303: 8-9. In France blood donation is declining, for a number of reasons; BMJ
303: 153.
Comments on AIDS in Asia are in BMJ

in the United States", Science
253: 37-42. On the idea of making a risk of HIV infection country comparison table
for travellers see NS
(17 Aug 1991), 8.
The continued US policy for refusing entry to immigrants with HIV has meant that the
8th International AIDS conference has been shifted from the USA to Amsterdam; Nature
353: 96, 199; Science
253: 845; Lancet
338: 751; BMJ
303: 462, 665.
The question of HIV testing for health workers has been a major issue of debate.
It represents compulsory screening, and is thus regarded as unethical by many. The
US Center for Disease Control Recommendations for preventing HIV transmission from
health care workers is in JAMA
266: 771-6. See also JAMA
266: 1134-7, 1935-6; Lancet
338: 683-4; BMJ 303: 325-6, 351-2; NEJM
325: 888-9. In Germany, the health care minister has said that if workers do not
voluntary take tests, a compulsory law will be introduced; Lancet
338: 375.
The question of HIV testing and obtaining medical insurance in the U.K. is raised
in BME
(Aug 1991), 6-7; Lancet
338: 306. The request for the results of HIV tests by insurance companies could
result in people avoiding having HIV tests, which will be detrimental. On a campaign
in Britain to raise the awareness about the rights of HIV-infected and AIDS patients
see BMJ
303: 540-1. In the US, the Center for Disease Control is urging hospitals to test
all new patients for HIV; NS

303: 905-7; and after a positive test MJA
155: 142, and on informed consent for HIV testing see CMAJ
145: 518-20, 616-7.
The French scandal on the use of HIV-contaminated blood in blood banks asks why the
use of HIV-testing was delayed for 5 months so that a French test could be used instead
of the earlier US test; Nature
353: 197; Lancet
338: 809-10. In India many blood banks are contaminated by HIV-infected blood (only
5% of blood is screened), from professional donors who have been rejected from clinics
where there is screening; Lancet
338: 436-7.

303: 263; Science
253: 502, 1483. The recommendations of an American working party on how to do ethical
research on AIDS are reproduced in the BME
(Sept 1991), 8-11. The US government has redefined people who have AIDS, to be based
on the count of CD4 lymphocytes; Nature
352: 653. On the spread of HIV-1 in Africa see a review in Nature
352: 581-8. On the relatively low rate of female to male transmission of HIV see
JAMA

A study in Rwanda has shown that mother's appear to transfer HIV to babies via breast
feeding; P. van de Perre et al., "Postnatal transmission of HIV Type 1 from mother
to infant", NEJM
325: 593-8; Nature
353: 2; see also S. Allen et al., "HIV infection in Urban Rwanda", JAMA
266: 1657-63. This means that the transmissibility of HIV via breast feeding has
been shown, after some debate about its likelihood. On maternal HIV tests see Lancet
338: 386. On AIDS in children see JAMA
266: 770; CMAJ
145: 198-9, and on counseling families with HIV-infected children see Nursing Times

(24 Aug 1991), 19. See also Lancet
338: 940.
On counseling patients before an HIV test see BMJ
303: 1133-4, 1478. Denmark have banned the use of HIV tests by insurance companies,
and other countries may follow, but should HIV testing be a special case?; Lancet
338: 1212. Most AIDS patients appear to be pleased with their physicians in the
UK; M.M. Kochen et al., "How do patients with HIV perceive their general practitioners?",

In France, the government has announced that it will compensate people that were infected
with HIV-infected blood; EEIN
1:80;BMJ
303: 1091, 1156-7, 1417-8; Nature
354: 425. The issue has been a major scandal, and three officials have been charged;
Nature
353: 781. Ten German haemophilic patients that were infected with HIV are receiving
compensation from the producer of the blood clotting factor preparation; BMJ
303: 1352-3.
A call for partner notification is made in Lancet
338: 1112-3, especially because HIV-infected persons can benefit from treatment with
drugs to delay the onset of AIDS, and also it would benefit the society as people
become aware that they are infected and slow its spread to others. In Sweden this
policy has been used with good results; J. Giesecke et al., "Efficacy of partner notification
for HIV infection", Lancet
338: 1096-1100. On mucosal transmission of HIV; Nature

The
Japanese
government has decided to increase the funding of AIDS prevention and education programs.
It has been very slow in approaching AIDS, maybe at last it releases its importance,
especially given the promiscuity of Japanese businessmen in Japan and abroad. The real number of HIV-infected persons in Japan is estimated to be about 8600, though
officially the latest figure is 2008. The government will attempt to protect privacy
more, to encourage more people to take tests. They also reported a case of a patient developing AIDS only 8 months after HIV infection (similar to reported cases in
France and Holland where the virus appears to attack the immune system at a 3 times
faster rate than normal).
The law can be used to enforce behaviours of people with infectious diseases, but
it does not appear to work well for sexually-transmitted diseases; BMJ
304: 891-2. See also; NEJM
326: 703-5. It appears that many HIV infected people do not
inform
past sexual partners of their infection risk; Public Health Reports
107: 100-9. A study suggesting that women are about twice as likely to get HIV from
men via heterosexual intercourse is BMJ
304: 809-13. Ways to counsel HIV positive haemophilic men who wish to have children
is discussed in BMJ
304: 829-30.

hospital, London are shown in Lancet
339: 364.
The Victorian government in
Australia
has announced that it will provide
compensation
for all people who medically acquired HIV and AIDS; Lancet
339: 419. It is being debated in Australia, because it calls such people "innocent"
victims, while critics ask whether other AIDS patients are "guilty" victims. The
duty to attend upon sick people, and to treat all people with HIV is discussed in
JAMA
267: 1467-9.
Methods to prevent neonatal herpes, including the use of condoms in sex during pregnancy
for carriers of herpes simplex virus are discussed in NEJM
326: 946-7, 916-20. A survey of behaviour of condom use is J.-P. Moatti et al.,
"Determinants of condom use among French heterosexuals with multiple partners", AJPH
81: 106-9. The US Centers for Disease Control has abandoned its pans for an AIDS
survey; Science

304: 402, 456-7. The French government is seeking to receive all of the US$20 million
in HIV test royalties the US government has received, because of the research showing
that French researchers were the first discoverers of HIV as a cause of AIDS, and
the Robert Gallo of the NIH in the USA used French virus to develop such tests; BMJ
304: 660; Science
255: 792.
In the
UK
,
home HIV test
kits
have been
banned
; BMJ
304: 864. The Dept. of Health banned advertising, supplying or selling any such
kit for use without the aid of a medical practitioner. In the US, such kits are
being produced. Insurance in the UK and HIV testing is discussed in Lancet
339: 682-3. AMA policy on HIV testing is in JAMA
267: 792.
The situation in China is summarised in Liu Ben-Ren, "Legal regulations of AIDS detection
and administration in P.R. China", IJB
3: 25-7. Included in the regulation are "once a doubtful AIDS patient is found,
the unit must make diagnosis, report, give treatment". There appears to be confusion
between the word AIDS patient and HIV-infected person. The Chinese regulations appear
to enforce HIV testing.
In Thailand, which has a very large AIDS problem, associated with its huge sex industry,
the AIDS program has been toned down because of its dampening effect on the tourist
industry; BMJ
304: 1264; Newsweek (29 June 1992), 10-16.
The test stock for testing HIV vaccines in the USA has been contaminated by another
HIV strain, which means delays in proposed tests while a pure stock is redeveloped;
Science
256: 1387. On construction of AIDS vaccines see PNAS
89: 3879-83.
As noted above, DDC has been licensed by the FDA in the USA to treat HIV. The results
of a epidemiological study in the USA suggesting that early treatemnt with AZT improves

practice", Science
256: 1165-71, 1155-2, 1130-1. The results of DNA analysis suggest that the dentist
contaminated five patients with HIV. The case of a UK surgeon found to be HIV infected
is reported in BMJ

Nature
357: 188-9; Lancet
339: 1286-7; and on the origins of HIV see Lancet
339: 867-8. Meanwhile, five family groups for HIV have been reported, increasing
the previous estimated number of groups; Science
256: 966.
In the UK, as in many countries, people who die from AIDS may have another cause of
death recorded on their death certificate. This phenomenon is not novel to AIDS.
It is debated in Dispatches
2(3), 6-7. The views of HIV infected persons in the UK on the use of advance directives
are reported in Dispatches
2(30, 8-10.
The
attitudes
of health carers to
treating HIV-infected persons
is reported in M.F. Shapiro et al., "Resident's experiences in, and attitudes toward,
the care of persons with AIDS in Canada, France and the United States", JAMA
268: 510-5. There was more reluctance to treat patients in the USA than in France
and Canada. At a recent conference it was remarked that the reluctance of health
workers to care for the sick is a significant symptom of the decline in morals of
caring in recent times. The counseling and testing of patients in US hospitals is surveyed
in NEJM
327: 445-52. A survey of the occupational blood contact and HIV infection in orthopedic
surgeons in the USA found that blood contact was common, but transmission rates of
HIV low; JAMA

In
Japan
, more patients infected with HIV from blood transfusions are claiming compensation
from the Ministry of Health and Welfare for its failure to screen blood and using
imported blood. There has still not been any award to such persons of families of
deceased. There was a proposal to establish a hospice for AIDS patients but it is criticised
by patients as discrimination; Yomuiri Shimbun
(2 Sept 1992), 30. Papers on the risks of transmission are in NEJM
327: 419-21. On the Australian compensation see Lancet
339: 1615. AIDS and US politics is debated in Lancet
340: 105-6; BMJ
305: 136.
The Board of Education in
New York
has voted to require people who teach about AIDS in schools to say that they will
"devote substantially more time and attention to
abstinence
than to other methods of prevention". In an editorial in Nature
359: 2, they call this thinking of the dark ages. The question is whether it is
going to be understood by the listeners, and whether it will be effective against
transmission of AIDS. In some cultures it may be effective, with ethical and religious
support, however, it may be too late to attempt to change teenagers sexual behaviour when
it has become a social norm in some cities. While efforts should be made to promote
"family values" in the short-term moves are needed to reduce HIV transmission. A
study from the UK is A.J. Hunt et al., "HIV infection in a cohort of homosexual and bisexual
men", BMJ
305: 561-2.
In
Japanese
schools there has been some controversy regarding giving out free condoms. Considering
that this is the first year that sex education has been introduced into the school
curriculum across Japan, it is not surprising that there are some schools which disagree with the issuance of free condoms. One school asked students to give back condoms
that had been distributed, with 90/135 students complying. Due to the limited availability
of the contraceptive pill in Japan, condoms are a major form of contraception, and have been available in stores for many years. The funding for AIDS research
in Japan may increase dramatically, five-fold, in Japan in 1993; Nature
358: 699. In the current fiscal year, Y900 million will be spent in Japanese schools
and universities on AIDS education.
In Japan there are fears that many of the annual 700,000 travellers to Thailand will
lead to rapid growth in AIDS cases. Some companies have been educating employees
who go on foreign trips. In Ibaraki prefecture, 90% of AIDS cases are foreigners.
This has lead to some discrimination problems, and education is urgently needed. The
first time that AIDS patients who got HIV from sexual intercourse have openly said
so, was this year. Free testing in Tokyo is being offered.
Many hospitals have said that they are not prepared to treat patients with AIDS, and
a hospital in Sendai recently refused to admit a pregnant women who
refused
a blood test for HIV; Yomiuri Shimbun
(10 Oct 1992), 31. Tsukuba University Hospital has said that it will still treat people
who refuse HIV tests. The Ministry of Health and Welfare has said it is illegal
to discriminate against HIV-infected or AIDS patients, as AIDS is not the same as
a controlled infectious disease. There comment follows cases of hotels refusing to accept
guests who were HIV infected; Yomiuri Shimbun
(29 Sept 1992), 31.
The positive effect of celebrity announcements on AIDS and behaviour is surveyed in
S.C. Kalichman & T.L. Hunter, "The disclosure of celebrity HIV infection: Its effects
on public attitudes", AJPH
82: 1374-6. In Japan also celebrities are being involved in AIDS education, though
only a few are HIV infected.
The relationship between blood donation and virus transmission is the subject of a
letter in Lancet

liability
bill, to limit liability for companies who develop AIDS
vaccines
in the USA has been introduced to encourage research; Science
257: 1035. A commentary on AIDS vaccines and immunotherapy is in Biotechnology
10: 1086-7. There is criticism of AIDS vaccine research in NS

clinical trials
and AIDS are discussed in an Institute of Medical Ethics Working Party report on
the Ethical implications of AIDS, "AIDS, ethics, and clinical trials", BMJ
305: 699-701. The legal view on whether knowledgeable "HIV transmission" should
be a
crime
is discussed in Lancet

Danish
case debating this issue is reported in Lancet
340: 719-20, which also involves the disclosure of medical records to the police.
Chinese
students returning home for holidays or for good in China may be forced to undergo

many nations, in India or Africa; NS
(5 Sept 1992), 20-1. One sample in India among professional blood donors found that 172/200
were HIV positive.

In
Japan
, a telephone survey on the 28-29 November by NHK with 1,800 people over 20 years
of age (with 1,488 responding) looked at attitudes to HIV-infected people. Asked
whether they would see friends after they knew they were HIV positive, 41% said they
would continue to see them regularly, 43% said they would see them less often and 11% said
they would stop seeing them. Of those who would see their friends less often or
no more, the figures were higher for those who did not understand the method of transmission (based on some knowledge questions about AIDS); NHK Television Main News Program,
7pm, 30 Nov. The local Ibaraki prefecture government has decided to give out 45,000
free HIV test vouchers to all the 20 year olds on the special holiday "coming of
age" day on 15 January; Yomiuri Shinbun
(11 Dec 1992), 30. The prefecture government has special celebrations for all the people
who will turn 20 years old in in this year - so will take the opportunity to give
these vouchers. Ibaraki has the highest HIV rate, after Tokyo.
Many health workers in Japan are
refusing
to treat
AIDS patients, basically due to lack of understanding of the transmission. The same
debate has occured in other countries in the past, with fears of contracting HIV
(EEIN
2: 65). Comments on how to lessen the number of needlesticks are in Science
258: 34; and on protection from HIV and hepatitis in body fluids see BMJ
305: 1337-43; Lancet
340: 1279. The potential of cross-contamination with dental equipment suggests several
changes in dental practice; Lancet
340: 1252-4; 1259-60.
A new book looking in an international way at policies regarding AIDS is David L.
Kirp & Ronald Bayer, eds., AIDS in the Industrialized Democracies. Passions, Politics, and Policies,
(New Brunswick, N.J., Rutgers University Press 1992, 393pp.). It includes comprehensive
chapters on the contrasting approaches used in Australia, Britain, Canada, Denmark,
France, Germany, Japan, The Netherlands, Spain, Sweden, and USA. It can be recommended for anyone interested in AIDS, and also for those interested in the way that
different countries and societies have responded to it. The ethical issues however
may be similar, basically to seek to educate against discrimination, and the need
for education to aid prevention of spread. The experience described in the book, and the
further experience as this decade unfolds, is useful in developing policies to combat
AIDS and can also be applied to other diseases, including testing for genetic diseases.
The positive effect of
celebrity
disclosure of HIV status on the number of young people undergoing HIV tests in the
USA is shown in NEJM
327: 1389; AJPH
82: 1483-9. In the USA about 43 million have had HIV tests, but still many more
are needed among high risk groups; AJPH
82: 1533-5.

From January people visiting
Israel
for more than 3 months will need to be tested for HIV and if they are positive they
will be limited to 3 months stay; NS

Britain
people may still be asked on applications for life
insurance
whether they have had a HIV test (+ or -), despite government criticism; BMJ

306: 335-6. In
Japan
, there have been 68 incidents involving needle sticks with contaminated serum, but
only one case, of a mother being infected, has lead to virus transmission. However,
a survey by the Japan Hospital Association has reported that 40% of hospitals refuse
HIV positive patients; Yomuiri Shinbun
(16 Feb 1993), 26. In the USA there is a legal as well as ethical duty to treat, J. Cohen,
"Access to medical care for HIV-infected individuals under the Americans with Disabilities
Act: A duty to treat", AJLM

In
Japan
, on the 15 January the Ministry of Health and Welfare talked for the first time officially
with AIDS patients; Yomuiri Shinbun
(15 Jan 1993), 31. A survey of AIDS in Japan; Yomuiri Shinbun

The Dept. of Defense and the NIH in the USA have convened separate panels to ask how
to spend a US$20 million grant for AIDS
vaccine
tests (EEIN
3: 17); Science
259: 752-3. The grant was given to sponsor a trial using a gp160 vaccine made by
the company, MicroGeneSys; Science
260: 19. The NIH did not think it was appropriate to allocate a specific product,
rather the NIH should decide. They are deciding which vaccines to test. In a recent
move, the gp160 vaccine has been withdrawn by the company in a comparative trial
of three vaccines - a move that is criticised by the NIH because it will avoid competition
with two other vaccines; Nature
362: 277; Science
259: 1821-2. In May a trial on newborn babies is expected to commence in the USA;
NS
(20 Feb 1993), 9. An editorial in Nature
362: 576; criticises any vaccine trial as a waste of money. Also on vaccines, Nature
362: 212, 503-6.
Recent data; Nature
362: 355, suggests that within a few weeks of infection, HIV has seeded the lymph
nodes and is present in the blood, so that a therapeutic vaccine may be too late.
On the
mechanism
see NEJM
328: 327-35; Nature
361: 588-9, 650-4, 362: 103-4, 287, 292-3, 355-8, 359-62; Biotechnology

341: 820; SA
(March 1992), 22-3; JAMA
269: 1084; NS
(27 March 1992), 17; Science
259: 1749-54. Another strategy to attempt to combat AIDS has been suggested - that
of concentrating drugs against the reverse transcriptase enzyme, that is needed for
replication. The cases of AIDS without HIV remain mysterious; NEJM
328: 373-9, 380-5, 386-92, 393-8, 429-31; BMJ
306: 477. The cases do not appear to be due to another virus. It has now been a
decade of research on AIDS, and it is still to be cured; Nature
362: 13.
Discussion of the idea of a huge AIDS research project is in Science
259: 1112-4; NS
(20 March 1992), 11; (3 April 1993), 14-5. The NIH has announced that it intends to commence
drug trials in HIV infected persons as soon as it is known, in efforts to curb HIV
earlier in its attack in the body; Nature
362: 382; JAMA
269: 1144-53. The need for a new drug; Nature
362: 396, is even stronger following reports of the
ineffectiveness of AZT
; Lancet
341: 889; Nature
362: 483, 493; Science
260: 157. AZT may still have some uses in people who have AIDS disease, but it does
not help those who are only HIV-infected. The final outcome will be the same whether
they use it or not, so they don't need to take it until they actually get AIDS.
The production of AZT in India is underway, at cheap cost; Lancet
341: 485. They plan to export the drug to other countries. Some people appear to
be immune to AIDS, and certainly there are individual differences in lag time; Time
(22 March 1992), 41-3; Lancet
341: 624.
In the UK there has been increasing debate about HIV
testing
of
health care workers

A test allowing identification of free HIV in blood within
three hours
has been developed by university researchers (UCSF) in the USA; GEN
(1 Mar), 32. They use an ELISA test for the core p24 antigen of HIV; NEJM
328: 297-302; Lancet
341: 502. It is suggested for use in neonates born to infected mothers. In France
there is more controversy about HIV testing, following the closure of a company that
used pooled tests and the revelation that the government blood screening lab has
also used the cheaper method; NS
(27 March 1992), 11.
The adverse
Arab
attitudes
to AIDS and under reporting of AIDS are discussed in Lancet
341: 884-5. The continuing
stigma
associated with AIDS is reported in survey results in AJPH
83: 574-7, and US public awareness of the availability of HIV testing was surveyed
in AJPH
83: 525-8. In a US study about a quarter of the men and one third of the women who
had been notified that they had HIV had symptoms of depression; AJPH
83: 534-9. In a US clinic the rate of sexually transmitted diseases decreased in
HIV positive patients, but increased in those who tested negative, suggesting a need
for better counseling; AJPH
83: 529-33.
The ethics of
confidentiality
for AIDS patients and HIV carriers is discussed in JME
18 91992), 173-9; JAMA

83: 496-7. The problems and approaches in telling a child that they have AIDS are
discussed in HCR
23(2), 6-12. The issue of AIDS deception by doctors is discussed in JME
18 91992), 180-5. In India AIDS will remain a non-notifiable disease in order to
protect confidentiality; Lancet
341: 684. Also on ethics and testing see AJPH
83: 597-8.
A
prison
sentence does seem appropriate for convicted transmitters of HIV virus, who willingly
continue unprotected sex; Lancet
341: 751-2; NS
(20 Feb 1993), 5. However, the prison environment is a high risk place for HIV; NS
(20 Feb 1993), 12-3. There have been changes in the habits of injecting drug users in
Scotland; BMJ
306: 693. On the sexual habits of drug users in the UK, which are similar to the
general public, see Nature
361: 504-5. On sexual behaviour see BMJ
306: 582-3. However, unsafe sex and HIV transmission has increased again in homosexual
men in the UK, following the initial decline; BMJ
306: 426-8. Comments on efforts in Africa to get safer sex habits are in NS
(27 Feb 1993), 12-3. A paper on the risk factors associated with HIV among male prostitutes
is AJPH
83: 79-83; and the AIDS knowledge among poor women in the USA is surveyed in AJPH
83: 65-71. Also on sex and HIV see JAMA

306: 792; Lancet
341: 863-4; Biology of Reproduction
48: 431-45; AJPH
83 (April 1993). The new female condom was discussed in the birth control section above,
it is also seen as a boost to preventing HIV transmission; AJPH
83: 498-500.
In
Japan
, a survey of new company recruits found that 85-7% of them would be happy to work
next to people who had HIV; Yomiuri Newspaper
(30 March 1992), 30. 50% did say that they had some resistance, but it was OK, while
30% said that they would try to look out if they could help them. In April special
AIDS prevention books were distributed to all the national university staff in Japan.
The real number of HIV-infected people in Japan is estimated to be 23,220, 8 times the
official figure. However, the real figure is hard to predict. Hospitals continue
to turn patients away if they have HIV, and recently a Thai woman ended up being
paralysed because she was moved to 3 hospitals over several days, all refusing to treat her
(though some not openly citing HIV), so that it became too late to perform surgery.
She is suing them from Thailand.
The US Senate voted 76 to 23 to continue a ban on entry restrictions for HIV infected
persons in the USA, reflecting public opinion, and against the wishes of President
Clinton and many in the medical community who see no benefit from the ban; Lancet
341: 620-1. The global needs of AIDS research are emphasised in statements by US
government officials; JAMA
269: 1636-7, yet their policy is discriminatory. A US National Research Council
Report has angered some people because of its conclusion that most Americans are
not at threat from AIDS, and that the impact will be small; Lancet
341: 429-30; BMJ
306: 674-5. It says those at risk are in "marginalised social groups", so the impact
will be small on others, but, we should be attempting to reduce such margins.

Thailand
. In
India
trials of a US vaccine are also expected; Nature
363: 294. In the USA, the US$20 million given to the Dept. of Defense, that raised
controversy for six months (see previous issues), has been transferred to the NIH,
who will choose how to spend the grant; Lancet
341: 1014; Nature
363: 294. In general on trials see BMJ

In
Japan
AIDS continues to be given much attention in the media. In a case in may at the
University of
Tsukuba
Hospital, a man was tested for HIV without his consent after his wife said that she
had told him. The problem was that they could not speak English or Japanese, and
the doctors could only trust the wife. She had tested HIV positive and wanted to
test him before telling him, because she was scared of the reaction; Yomiuri Shinbun
(20 May 1993), 27. This case is also disturbing because the newspaper reported details
which could threaten the privacy of the couple, though nationalities were not revealed.
The story was leaked by an anonymous insider, perhaps not with the interests of
the couple at heart. The Tsukuba hospital is one of the hospitals that accepts HIV infected
patients, many others in Japan do not.
A review of phase III trials for AIDS
vaccines
is Nature
364: 489-90. The debate over the US Army trial of a gp160 vaccine may continue,
but the decision has been made for the Army to go ahead with their US$20 million
clinical trial solely using a vaccine made by one company, MicroGene Sys, to the
dismay of many AIDS researchers; Nature
364: 374, 751; BMJ
