New
Leprosy Vaccine Developed
The National Institute of Immunology has
developed a new vaccine for leprosy treatment as
announced on the Anti-Leprosy Day, on 30th January 1998.
The vaccine will be launched under the brand name, Leprovac,
by Cadilla Pharmaceuticals, in the next three months. The
vaccine will not cure leprosy but will hasten the process
of recovery in case of patients undergoing the multiple
drug therapy by about 18 months from the standard period
of two to four years. Research on the vaccine started in
1972. The new vaccine is priced at Rs 6 per dose and the
overall expense incurred by a patient on the vaccine will
be less than Rs 50 during the course of the treatment.
The Net that Zaps
Mosquities
Doctors and drug companies are getting
exasperated over their inability to counter drug
resistant malaria. The Health Ministry has come out with
a novel method to tackle the problem - use of
chemically-coated nets which are safe for humans but
deadly for mosquitoes. A pilot project in Assam, where
one lakh mosquito nets were given to villagers in the
worst hit area of Sonapur in Kamrup district, has
succeeded in bringing down malignant malaria cases by
over 70 per cent. From over 500 reported deaths a year
between 1993-96, the mortalities declined to 150 in
1996-97. Encouraged by the results, the ministry has
proposed to distribute over a million nets in the
North-East, Bengal and Orissa. The washable nets will
also be sold so that people in semi urban areas and
cities can buy.
The chemical, deltamethrin,applies itself better to nylon
nets than cotton ones, and one
application can be effective for six months. The effect
lasts up to three washes, its intensity reducing with
every wash. Mosquitoes and other insects die on contact
after a fresh application and subsequently are kept at
bay for days. The nets also help reduce vector density in
villages. The procedure for impregnation is simple and
can be done by communities themselves. A 10 ml dose,
diluted in 200 ml of water is enough for the complete
absorption by one mosquito net. Unlike other
insecticides, this does not leave a foul smell, neither
during application nor in use.
Drug resistant malaria wasfirst noticed in the Himalaya
foothill areas of the North-East It is now rampant in all
the seven states of the region. It has also been recorded
in Bengal and Orissa since the last monsoon. According to
health ministry statistics, there were 2500 reported
deaths from malaria during 1996-97 from all over the
country.

The Mefloquine
Story
Mefloquine, a 4 - quinoline methanol compound
chemically related to quinine, is now available in India.
Marketed under the trade name Mefleam by
Cipla, it is available as tablets containing 250 mg of
mefloquine. Mefloquine is a potent, long-acting blood
schizonticide active against malaria parasites resistant
to chloroquine, sulfonamide/pyrimethamine combinations
and other 4 - aminoquinolines. As it is very slowly
eliminated (plasma half life 10 to 40 days), a single
weekly dose of 250 mg provides effective prophylaxis. In
uncomplicated malaria a single dose of 15 mg/kg body
weight is usually adequate.
In India mefloquine is recommended only as a second line
drug in the treatment of malaria. It should ideally be
used only for the treatment of chloroquine resistant
malaria and not as a prophylactic or for the treatment of
uncomplicated malaria. Almost one every five persons who
take mefloquine prophylactically notice some dizziness,
nausea, vomiting, diarrhoea, or abdominal pain. These
symptoms are generally mild and resolve without specific
treatment. Over a ten-year period starting in 1985 more
than 1500 neuropsychiatric adverse events, associated
with mefloquine were reported. The most common were
affective disorders, anxiety disorders, hallucinations
and sleep disturbances. WHO currently advises that
mefloquine may be given safety during the second and
third trimesters of pregnancy both for prophylaxis and
treatment. Bradycardia and sinus arrhythmia is estimated
to occur in some two-thirds of patients treated with
mefloquine. There may be ECG changes, when used with
related anti-malarial drugs.

The Plague
Epidemic and After
The panic generated by the plague epidemic both
in India and abroad resulting in hardships to thousands
is now well documented. The Institute of Public Health,
based in Chandigarh, under the leadership of Dr Satnam
Singh, a long time WHO expert, was involved in
understanding how the State and Central government
institutions have been coping with the outbreak with a
view to evolving a communicable disease surveillance and
control strategy in the country on a scientific basis,
since 1994.
By December 1995 there were four reports on the incident
available. The WHO International team report on Plague in
India, 13-26 October 1994 concluded that No
evidence was found to suggest transmission of Y. pestis
in any major urban population other than in the city of
Surat. A report by an expert committee appointed by
the Gujarat Government which appeared in March 1995
concluded that the majority of evidence does not
support the initial suspected diagnosis of pneumonic
plague. The Government of India Technical Advisory
Committee on plague provided very strong
evidence in favour of plague being the cause of
deaths in Surat.
Dr. Singhs report containing elements of quick
research concluded that no evidence of man-to-man
transmission of the killer disease was obtained. In view
of the diverging conclusions of these reports Dr. Singh
had approached the India International Centre, New Delhi
and the Health Ministry of the Government of India to get
together about a dozen government and non-government
sector health scientists from different disciplines
including at least one from Surat to deliberate and
arrive at a consensus on whether the 47 deaths reported
in Surat between September 21 to 30 1994 were caused by
pneumonic plague. As such a deliberation which required a
period of about two days could not be arranged so far
either by the Ministry or ICMR or IIC.
Even after writing to two Health Ministers and Prime
Minister, the matter has not moved further. This leaves
the job for the new government to resolve the plague
issue so that it can make corrective short and long-term
national plans for infectious disease surveillance and
control in the country.

Insulin
Information
A new genetically-engineered human insulin
called Humalog, which is absorbed rapidly into the
circulatory system, is now available. It enables
diabetics to inject insulin immediately before meals. The
new drug may help insulin-dependent diabetics whose meal
times are unpredictable and those who eat late in the
evening and are prone to early nocturnal hypoglycemia.
Insulin-dependent diabetics usually reply on balancing
diet with a mixture of soluble (fast acting) and isophane
(delayed action) or a similar type of insulin to control
their ailment. If their stabilisation fails, they suffer
hypoglycemia, displaying symptoms of sweating, fainting,
loss of speech and sight, and finally unconsciousness.
The injections are usually given 30 to 40 minutes before
a meal.
Compared to human-soluble insulin, Humalog has a faster
action (15 minutes, as compared to 45), a shorter time to
the peak action (30-70 minutes against one-three hours)
when injected subcutaneously. So far, there is no data on
mixing Humalog with intermediate and long-lasting
insulins, which is likely to be a central figure of
therapy, subject to further trials.
