Can a pregnant woman get tb
Eur Respir J Dec Increased incidence of active TB during pregnancy and postpartum was found predominantly among women who immigrated from countries with high tuberculosis incidence. During pregnancy, the immune response is physiologically altered, with less tumor necrosis factor TNF secretion and reduced T-helper cell 1 function. Theoretically, these changes should make pregnant women more susceptible to reactivation of latent tuberculosis TB , an opportunistic infection commonly associated with impaired TNF secretion or attenuated T-helper cell function.SEE VIDEO BY TOPIC: Can a pregnant mother give tuberculosis to her child? - Dr. Cajetan Tellis

Can a person who has TB disease have children?
Jyoti S. Tuberculosis is most common during a woman's reproductive years and is a major cause of maternal—child mortality. National guidelines for screening and management vary widely owing to insufficient data.
In this article, we review the available data on 1 the global burden of tuberculosis in women of reproductive age; 2 how pregnancy and the postpartum period affect the course of tuberculosis; 3 how to screen and diagnose pregnant and postpartum women for active and latent tuberculosis; 4 the management of active and latent tuberculosis in pregnancy and the postpartum period, including the safety of tuberculosis medications; and 5 infant outcomes.
Finally, we highlight research gaps in tuberculosis in pregnant and postpartum women. In this article, we review the current state of knowledge, highlighting those gaps. The human immunodeficiency virus HIV epidemic, reduced healthcare access, and hormonal changes likely make tuberculosis a leading cause of morbidity and mortality in women of reproductive age [ 5—7 ].
Rates of active tuberculosis ranges from 0. High-burden countries may underestimate prevalence because many women do not have access to healthcare when pregnant [ 1 ].
Latent tuberculosis prevalence in pregnancy likely mirrors that of the general population, which is 4. It is up to 10 times higher among foreign-born Americans [ 23 ], including pregnant women [ 11 ], regardless of HIV status. Inconsistent screening complicates estimates of latent tuberculosis prevalence in high-burden countries. Pregnancy suppresses the T-helper 1 Th1 proinflammatory response, which may mask symptoms while increasing susceptibility to new infection and reactivation of tuberculosis [ 30—32 ].
These effects are seen in other infectious diseases, such as influenza and Mycobacterium leprae , which are more common and severe during pregnancy [ 33 ]. After delivery, Th1 suppression reverses—similar to immune reconstitution syndrome in HIV patients starting antiretroviral therapy ART —and symptoms are exacerbated [ 31 ].
A large study recently found that early postpartum women are twice as likely to develop tuberculosis as nonpregnant women [ 34 ]. This and other studies suggest that biologic changes in pregnancy and postpartum influence tuberculosis epidemiology [ 4 , 14 , 35 , 36 ], challenging the findings of earlier, smaller studies that found no effect [ 37 , 38 ]. Practitioners should be cognizant of the unpredictable symptomatology of tuberculosis during pregnancy. Tuberculosis increases mortality during pregnancy or postpartum, especially in HIV-positive women [ 14 , 39—41 ].
Lack of awareness is a barrier to diagnosis in low-burden countries. In high-burden countries, healthcare workers often lack diagnostic tests, relying on clinical presentation.
Women are less likely than men to present with symptoms like hemoptysis, fever, and night sweats [ 49 ], and pregnancy further masks these symptoms. In Tanzania, the most common tuberculosis symptoms were malaise and anorexia [ 17 ]. Many tuberculosis-endemic countries also have a high prevalence of HIV, which further masks symptoms and causes atypical symptoms.
Acid-fast bacilli stains and chest radiographs are less sensitive in HIV-infected patients [ 50 ], and cultures can take 4—10 weeks to become positive. The complex symptomatology notwithstanding, WHO recommends screening for symptoms of cough of any duration, fever, night sweats, and weight loss [ 51 ]. In symptomatic women and asymptomatic women with a recent tuberculosis contact, the Centers for Disease Control and Prevention CDC and others recommend a shielded chest radiograph, which poses minimal risk to the fetus [ 54—56 ].
If findings are abnormal, sputum samples should be submitted for microscopy and culture [ 56 ]. Note that chest radiography and sputum examination may miss miliary and extrapulmonary tuberculosis disease. Common extrapulmonary sites of tuberculosis in pregnancy include lymph nodes, intestines, and bones [ 44 , 58 ]. Additional diagnostic testing eg, biopsy should be pursued if clinical suspicion is high. Some experts advocate integrating active tuberculosis case-finding into peripartum care, but best approaches are unknown.
Universal antenatal tuberculosis screening in South Africa found that symptoms of tuberculosis were common whether or not the patient had tuberculosis, wasting resources on unnecessary evaluations [ 19 , 20 ]. Cost-effective tuberculosis screening approaches are urgently needed. Screening for latent tuberculosis should identify patients at high risk of developing active disease who would benefit from prophylactic therapy.
Both tests have other limitations. TST, because of potential cross-reactivity with BCG and environmental mycobacteria, as well as challenges with proper test placement, has low specificity and sensitivity, particularly among HIV-positive patients [ 59 , 60 ] and possibly among pregnant women [ 24 , 60 ].
IGRAs do not cross-react with BCG or environmental bacteria and do not require a return visit; but are costly, require blood collection, proper processing, and lab infrastructure, and have not been widely validated in high-burden settings or among pregnant women [ 61 , 62 ], although a study group of pregnant HIV-positive Kenyan women with a positive IGRA showed a 4.
Epidemiological eg, recent tuberculosis exposure and biological factors eg, malnutrition, immune changes of pregnancy may explain this, although the significance of this discordance needs further study [ 61 , 63 , 64 ]. Pregnancy by itself is not considered high-risk. In high-burden countries, latent tuberculosis screening is not routinely recommended, though TST screening is useful for identifying the HIV-infected patients most likely to benefit from isoniazid INH preventive therapy IPT [ 51 , 66 ].
TB between the tuberculosis antigen and negative control sample, regardless of HIV status [ 67 ]. Neither organization comments on IGRAs in pregnancy [ 62 , 68 ]. Adequate data assessing the safety, tolerability, and long-term treatment outcomes of pregnant and postpartum women with tuberculosis are lacking, particularly for HIV-positive women on ART. The benefits of treatment during pregnancy, however, outweigh the risks [ 69 ]. Pregnancy changes tuberculosis treatment very little.
INH rarely causes peripheral neuropathy in well-nourished adults. Pregnancy may increase risk, but this is not well studied. Pregnant women on INH should take pyridoxine to prevent this complication. Some experts recommend vitamin K for infants born to mothers taking RIF because of its potential association with hemorrhagic disease in newborns [ 72 , 73 ].
RIF also has drug interactions, including decreased efficacy of oral contraceptives. Adjunctive nonhormonal contraceptive methods in postpartum women are advisable [ 74 ]. High doses of EMB are associated with retrobulbar neuritis in adults, but no findings have been reported in infants of mothers taking EMB [ 72 , 73 ]. Most individuals with active tuberculosis become sputum smear-negative within a few weeks of antituberculosis therapy ATT.
Pregnant and postpartum women should submit sputum samples at least every 2 months until 2 consecutive samples are negative. Failure to become sputum-negative may indicate poor adherence or drug resistance. More frequent sputum checks may help determine when the mother is no longer infectious to her infant, but no evidence-based guidance exists. Follow-ups are essential to monitor maternal treatment response and assess for tuberculosis infection or disease in the infant [ 70 , 71 ]. Efavirenz is usually delayed until the second trimester because of neural tube defect concerns.
Recent data, however, suggest that efavirenz may be safe in all trimesters [ 78 ] and, as of , the British HIV Association's guidelines no longer prohibit its use in pregnancy [ 79 ]. Nevirapine-based ART is generally not recommended in women with tuberculosis, as rifampin significantly reduces nevirapine concentrations [ 80 ].
Rifabutin can be substituted for rifampin if a PI is used, but optimal dosing of rifabutin is unknown and, in many settings, rifabutin is not readily available [ 81 ].
The dose of raltegravir, an integrase inhibitor, should be doubled with rifampin-based ATT, but the pharmacokinetics PK , drug interactions, and outcomes remain inadequately studied in pregnant and postpartum women [ 82 ]. If neither nonnucleoside reverse transcriptase inhibitors nor PIs are appropriate, triple or quadruple nucleoside reverse transcriptase inhibitor therapy may be considered, but higher virological failure rates are a concern [ 70 , 71 ]. Adequate and well controlled AWC studies in pregnant women have failed to demonstrate a risk to the fetus in the first trimester of pregnancy;.
Animal reproduction studies have failed to demonstrate a risk to the fetus and there are no AWC studies in humans AND the benefits from the use of the drug in pregnant women may be acceptable despite its potential risks;. Animal reproduction studies have shown an adverse effect on the fetus, there are no AWC studies in humans AND the benefits from the use of the drug in pregnant women may be acceptable despite its potential risks;.
There is positive evidence of human fetal risk based on adverse reaction data from investigational or marketing experience or studies in humans BUT the potential benefits from the use of the drug in pregnant women may be acceptable despite its potential risks.
Treatment of MDR tuberculosis in pregnancy should be individualized but there are no established dosage adjustments for pregnancy. It is critical to check drug interactions with all medications patient is taking. Some women terminate their pregnancy to avoid teratogenicity of ATT. While there are obstetric, fetal, and infant complications associated with MDR tuberculosis regimens, small case series suggest that good outcomes are achievable [ 88 , 91 ], but close monitoring is essential.
The infants showed no evidence of teratogenicity [ 89 ]. WHO recommends breastfeeding once the mother is smear-negative [ 71 , 92 ], because breastfeeding prevents other infections and malnutrition in resource-limited countries.
There have been no documented cases of tuberculosis transmission via breast milk since the development of ATT [ 93 ]. Women with tuberculosis mastitis should breastfeed from the unaffected breast. Breastfeeding women should be advised of potential risks, but there are no absolute contraindications [ 75 ].
WHO does not comment on whether to offer HIV-negative women INH during pregnancy, whereas the CDC recommends delaying treatment of latent tuberculosis until 2—3 months postpartum, unless the patient has had a recent known tuberculosis contact [ 96 ].
The results, however, were not statistically significant. INH-associated hepatotoxicity ranges from 0. Pregnancy induces cytochrome P [ ], which may increase the risk of developing drug-induced liver injury. Because symptoms of pregnancy overlap with those of hepatitis, some experts recommend monitoring labs every 1—2 weeks in pregnancy for at least the first 8 weeks of therapy regardless of symptoms [ 72 , ].
A decision analysis found that antepartum IPT had a higher mortality rate from hepatitis than postpartum, but proper monitoring negates this effect [ ]. Although the CDC and WHO recommend early treatment of latent tuberculosis in HIV-positive pregnant women [ 51 , 96 ], they may be at particular risk for drug-induced liver injury. HIV-positive pregnant women had 3.
Tuberculosis can be transmitted through hematogenous spread during pregnancy, aspiration of amniotic fluid during delivery, or respiratory droplets postpartum. Infant mortality rates from tuberculosis vary dramatically between studies. In a separate study, of 32 infants born to 38 mothers with MDR tuberculosis, only 1 infant died of pneumonia [ 91 ]. Studies are similarly inconsistent on other adverse effects of maternal tuberculosis on the infant.
There was no difference in outcomes among infants born to mothers treated for tuberculosis during pregnancy vs without tuberculosis in the United States [ 46 ], nor were there differences in perinatal complications in Indian women with tuberculosis lymphadenitis vs without tuberculosis [ 44 ].
Of infants born to mothers with MDR tuberculosis in Peru, similar complications occurred, although the rate was comparable to that of the general population [ 91 ]. Infants of HIV-positive women who developed tuberculosis in the first year were more likely to die and to be HIV-infected than infants born to mothers with HIV alone [ 14 , ]. Larger prospective studies are ongoing. IPT reduces the negative consequences of infant exposure to maternal tuberculosis, but it has been poorly implemented in high-burden countries [ ].
Women—especially pregnant and postpartum women—have been underrepresented in clinical trials, although progress has been made. In , the FDA recommended including pregnant women in clinical trials of any medication likely to be used in pregnancy [ ]. In , the Medication Exposure in Pregnancy Risk Evaluation Program was launched to study prescription medications during pregnancy [ ], but little information on tuberculosis medications has been collected.
Interventions affecting pregnant women also affect neonates. There is an urgent need for research in pregnant and postpartum women, including those who are HIV-positive, in these areas:.
WHO recommendation on tuberculosis testing in pregnancy
Infants of mothers with TB have increased risks of premature birth and perinatal death; pregnant women with TB are more likely to have complications during pregnancy; initiating TB treatment is associated with better maternal and infant outcomes than late initiation. The ANC recommendations are intended to inform the development of relevant health-care policies and clinical protocols. These recommendations were developed in accordance with the methods described in the WHO handbook for guideline development 2. In summary, the process included: identification of priority questions and outcomes, retrieval of evidence, assessment and synthesis of the evidence, formulation of recommendations, and planning for the implementation, dissemination, impact evaluation and updating of the guideline. Up-to-date systematic reviews were used to prepare evidence profiles for priority questions.
I was also experiencing dizziness and shortness of breath. She was talking about tuberculosis TB , a preventable disease that still kills an estimated 1. She was given medication, instructed to follow a healthy diet to support her recovery and told to breastfeed exclusively for six months. She was also taught proper coughing etiquette to prevent spreading the illness to family and friends.

What to Do About Tuberculosis in Pregnancy
Throughout history, tuberculosis has been a plague on mankind. Tuberculosis remains the most common cause of death from infectious agents in childbearing-age women 14 to 49 years worldwide. Overpopulation, human immunodeficiency virus HIV infection, increasing poverty, and the increasing incidence of antibiotic-resistant isolates are increasing the burden of tuberculosis on women and society. Cases of tuberculosis in childbearing women and their infants, when compared across gender and age, suggest a disproportionate number of infected women. When the reported cases of tuberculosis through in the United States is plotted by age, there are peaks in the first year of life about , age 35 , and a broader increase between the ages of 50 and 80 years to cases per year.
Untreated tuberculosis TB disease represents a greater hazard to a pregnant woman and her fetus than does its treatment. Treatment should be initiated whenever the probability of TB is moderate to high. Pregnant women who are being treated for drug-resistant TB should receive counseling concerning the risk to the fetus because of the known and unknown risks of second-line antituberculosis drugs. Breastfeeding should not be discouraged for women being treated with the first-line antituberculosis drugs because the concentrations of these drugs in breast milk are too small to produce toxicity in the nursing newborn.
Tuberculosis care for pregnant women: a systematic review
Tuberculosis TB is caused by a bacterium called mycobacterium tuberculosis. This microorganism is a highly aerobic, acid-fast staining rod. The bacteria usually infect the lungs, but may infect any part of the body, including the kidney, spine, and brain. If not treated, TB can be fatal.
Metrics details. Tuberculosis TB during pregnancy may lead to severe consequences affecting both mother and child. Prenatal care could be a very good opportunity for TB care, especially for women who have limited access to health services. The aim of this review was to gather and evaluate studies on TB care for pregnant women. Studies reflecting original data and focusing on TB care for pregnant women were included.
