The pregnancy of a woman who has sickle cell anemia and pregnancy is regarded as high risk particularly in India where the disease is prevalent in some areas. It is important to know when to begin or increase treatment so as to save both the mother and the baby.

The importance of Treatment during Pregnancy

• Pregnancy amplifies the demand of oxygen which aggravates sickling of red blood cells.
• SCD increases the risk of maternal death in women by 4–11 times.

Higher chances of:

• Severe anemia
• Pain crises
• Pre-eclampsia
• Preterm or low birth weight.
• This is the reason why timely treatment decisions are not an option.

At which stage is the treatment to be taken?

Before Pregnancy (Preconception Stage) 

• Best time to plan treatment

Consider treatment if:

• Various pain crises or hospitalizations.
• Severe anemia or complications of the organs.
• Pregnancy complications of the past.

Recommended approach:

• Genetic counselling (needed in India because of prevalence of carriers)
• Optimize hemoglobin levels
• Check drugs such as hydroxyurea 

Early Pregnancy 

• Critical evaluation phase

The treatment is contended in case:

• The level of hemoglobin reduces drastically.
• Past experience of severe SCD complications.
• Indicators of high-risk pregnancies.

What doctors may do:

• Begin folic acid self-treatment.
• Fetal and maternal close observation.
• Choose to use or drop disease-modifying drugs.

When Pregnancy (Second and Third Trimester) Occurs

• It requires treatment in case of complications.

Treatment should also be considered immediately in case:

• Recurrent pain crises
• Severe anemia (this may necessitate blood transfusion)
• Acute problems such as acute chest syndrome.
• Evidence of fetal growth retardation.

WHO guidelines suggest:

• Preventive blood transfusion in case of severe or frequent crisis.
• Symptomatic and history-based individualized care.

Emergency (Immediate Treatment required) Situations

Seek urgent treatment if:

• Acute chest pain / breathlessness.
• Very low hemoglobin levels
• Stroke-like symptoms
• Infection or fever

In such cases:

• Hospital admission
• Oxygen therapy
• Blood transfusion
• Strong pain management

Importance of Pregnancy Treatments 

• Folic acid pills: promote the manufacture of red blood cells.
• Pain management→ safe analgesic (as per trimester)
• Blood transfusion → severe anemia or complications.
• Prevention of infection: antibiotics, vaccination.
• Hydroxyurea > can be maintained in specific instances in the face of risk and benefit assessment.

India-Specific Considerations

• Increased rate in tribal and central/eastern areas.
• The screening and management are supported by government programs (as NHM).
• Care accessibility (hematologist + obstetrician) is necessary.

When Advanced Treatment (After Pregnancy) is to be considered

There are women who might require a conclusive treatment planning postpartum like:

• Bone marrow transplant (curative treatment)
• Long-distance disease-modifying treatment.

Conclusion

Sickle cell anemia has rendered pregnancy to be a high-risk situation that is manageable particularly in India where the burden of the disease is high in some populations. The secret behind the safe outcome is planning early, intervening in time and sustained follow up in all the stages of preconception till delivery. The treatment must not be postponed or taken when there is an emergency. Rather, it needs to be actively thought of prior to pregnancy, must be regulated each trimester, and enhanced whenever complications set in. Through proper medical support: folic acid, pain treatment, blood transfusion (where necessary) and infection prevention, the majority of women with SCA will be able to record successful maternal and fetal outcomes. Finally, a multidisciplinary team including hematologist and obstetrician, as well as the presence of the right healthcare facilities, is also very important. Long-term or curative choices should also be considered by the patients to enhance their overall quality of life post-pregnancy.
