Best practices for the care of pregnant people living with TB

BACKGROUND: Each year more than 200,000 pregnant people become sick with TB, but little is known about how to optimize their diagnosis and therapy. Although there is a need for further research in this population, it is important to recognize that much can be done to improve the services they currently receive.METHODS: Following a systematic review of the literature and the input of a global team of health professionals, a series of best practices for the diagnosis, prevention and treatment of TB during pregnancy were developed.RESULTS: Best practices were developed for each of the following areas: 1) screening and diagnosis; 2) reproductive health services and family planning; 3) treatment of drug-susceptible TB; 4) treatment of rifampicin-resistant/multidrug-resistant TB; 5) compassionate infection control practices; 6) feeding considerations; 7) counseling and support; 8) treatment of TB infection/TB preventive therapy; and 9) research considerations.CONCLUSION: Effective strategies for the care of pregnant people across the TB spectrum are readily achievable and will greatly improve the lives and health of this under-served population.

Breastfeeding in women living with tuberculosis

Breast milk provides optimal nutrition, and is recommended for neonates and infants. In women with TB, there has been uncertainty about optimal feeding practices due to the risk of transmission to the neonate and the possibility of drug exposure via breast milk. For women who have drug-susceptible TB (DS-TB) who are no longer infectious, it is safe to breastfeed as breast milk does not contain Mycobacterium tuberculosis bacilli and only minor, non-toxic quantities of the drugs pass into breast milk. Most guidelines therefore encourage breastfeeding in women with DS-TB. However, there is uncertainty and guidelines vary regarding women with DS-TB who are still infectious and in women with rifampicin-resistant TB (RR-TB). Although the transmission dynamics of DS- and RR-TB are similar, additional infection control precautions for RR-TB may be necessary until the mother is responding to treatment, as second-line therapy may be less efficacious and preventive therapy is not widely offered to infants. In addition, there are no published data describing the extent to which second-line drugs are secreted into breast milk or subsequent exposure in breastfed infants. The implications of limited information on policy and consequent dilemmas regarding patient care are illustrated in a patient scenario. Areas for future research are suggested.

Household context and psychosocial impact of childhood multidrug-resistant tuberculosis in KwaZulu-Natal, South Africa

SETTING

Referral hospital for drug-resistant tuberculosis (TB) in KwaZulu-Natal, South Africa.

OBJECTIVES

We conducted interviews with primary care givers of children admitted with multidrug-resistant TB (MDR-TB) during a 3-month period in 2015 to identify broader household challenges.

RESULTS

We interviewed 26 care givers, most of whom were women (85%). Most households had been decimated by TB/MDR-TB and human immunodeficiency virus (HIV) infection, and were dependent upon government grants. In 54% of cases, parents were absent due to illness or death, or their whereabouts were not known. The median age of the children treated for MDR-TB was 8 years (range 2-14); 72% were HIV-co-infected. Four themes emerged in the interviews: 1) the psychosocial impact of hospitalisation and separation on the child and the household, 2) the psychosocial impact of MDR-TB on children and 3) on care givers, and 4) the economic hardship of affected households. Children had to contend with multiple diseases and medications, and personal family losses; they faced behavioural, emotional and cognitive difficulties. Care givers were often anxious and concerned about the child's longer-term prospects, while the cost of hospital visits exacerbated the pre-existing economic vulnerability of affected households.

CONCLUSION

The socio-economic impact of childhood MDR-TB reverberates beyond diseased children to their affected households. Enhanced social protection, psychosocial support and treatment literacy would create the foundations for family-centred care.
