nausea, vomit<strong>in</strong>g, purities and<br />

exfoliative dermatitis. When<br />

adm<strong>in</strong>istered for prolonged periods, it<br />

may produce lenticular opacities and<br />

ret<strong>in</strong>opathy. The former disappears when<br />

the drug is stopped.<br />

An acute attack <strong>of</strong> malaria dur<strong>in</strong>g<br />

pregnancy should be treated promptly.<br />

To patients with severe nausea and<br />

vomit<strong>in</strong>g, chloroqu<strong>in</strong>e hydrochloride<br />

should be given parenterally until these<br />

symptoms subside. Severe anemia<br />

should is corrected by blood transfusion.<br />

There is no <strong>in</strong>dication for therapeutic<br />

abortion <strong>in</strong> these cases. No data is<br />

available with regard to possible<br />

teratogenic effects <strong>of</strong> chloroqu<strong>in</strong>e.<br />

Pyrimetham<strong>in</strong>e is another antimalarial.<br />

This is a folic acid antagonist and may<br />

cause abortion or fetal malformation if<br />

given dur<strong>in</strong>g early pregnancy.<br />

Dur<strong>in</strong>g pregnancy regular suppressive<br />

therapy should be cont<strong>in</strong>ued <strong>in</strong> non<br />

immune patients. It should be started by<br />

the end <strong>of</strong> the first trimester to prevent<br />

febrile paroxysms. A paroxysm consists<br />

<strong>of</strong> a chill which lasts for 20 to 60<br />

m<strong>in</strong>utes and high fever which can last<br />

for 1 to 4 hours and pr<strong>of</strong>use sweat<strong>in</strong>g.<br />

High fever can cause <strong>in</strong>trauter<strong>in</strong>e death.<br />

Chronic or latent malaria occurs as a<br />

result <strong>of</strong> repeated re <strong>in</strong>fections <strong>in</strong><br />

endemic areas. It is remarkably well<br />

tolerated by adult populations that have<br />

survived the disease s<strong>in</strong>ce <strong>in</strong>fancy and<br />

have acquired a high degree <strong>of</strong> immunity.<br />

Latent malaria may become active<br />

follow<strong>in</strong>g surgery, dur<strong>in</strong>g pregnancy, or<br />

after delivery.<br />

To give reliable protection to the fetus,<br />

an <strong>in</strong>creased dose <strong>of</strong> chloroqu<strong>in</strong>e<br />

phosphate i.e. 0.5 gm. every third day is<br />

156<br />

recommended dur<strong>in</strong>g the month before<br />

term. Suppressive drugs should be given<br />

to exposed <strong>in</strong>fants as soon after birth as<br />

possible. Most antimalarials are secreted<br />

<strong>in</strong> human milk. It has been suggested<br />

that a 50 per cent <strong>in</strong>crease <strong>in</strong> the dosage<br />

<strong>of</strong> suppressive drug given to a nurs<strong>in</strong>g<br />

mother can protect the breast feed <strong>in</strong>fant<br />

dur<strong>in</strong>g the first months <strong>of</strong> life.<br />

Chemotherapy will usually pre-vent<br />

anaemia when given at the onset <strong>of</strong> the<br />

disease but will not cure it once it has<br />

developed. Folic Acid 5 milligram daily<br />

should be given by mouth to pre-vent<br />

megaloblastic anemia) but trans-fusion<br />

will be required for severe anemia near<br />

term.<br />

Progressive hemolytic anemia<br />

can <strong>of</strong>ten be arrested by giv<strong>in</strong>g prednisone,<br />

20 milligram daily by mouth.<br />

Congenital malaria: The parasite can<br />

cross the placenta and cause<br />

"congenital" malaria. Its <strong>in</strong>cidence varies<br />

from 0.03 to 1 per cent. The parasites<br />

have special aff<strong>in</strong>ity for the decidual<br />

blood vessels. Infection occurs when the<br />

placenta is damaged. This breaks the<br />

marten fetal barrier. The placental<br />

barrier is <strong>of</strong>ten quite effective <strong>in</strong> immune<br />

patients.<br />

Symptoms: These are fever, vomit<strong>in</strong>g,<br />

convulsions" pallor, jaundice, and<br />

hepatosplenomegaly, which usually<br />

appears <strong>in</strong> the newborn 48 to 72 hours<br />

after birth. Death may result from acute<br />

pulmonary edema. Passive immunity is<br />

transmitted from mother to child, <strong>in</strong><br />

countries where malaria is endemic.<br />

Prophylaxis <strong>of</strong> congenital malaria<br />

In malarial areas all newborn <strong>in</strong>fants<br />

should be protected by mosquito nett<strong>in</strong>g,
