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. However, studies investigating an association of active TB with pregnancy have yielded conflicting results. To clarify this issue, researchers in Sweden, a country with low TB incidence, combined data from the national birth register with data from the national TB register.

NEJM Journal Watch
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. These peaks have been increasing over the past 10 years, in part because of the increasing incidence of HIV positivity and the increasing numbers of women at high risk for tuberculosis.
Although the male to female ratio of new tuberculosis notifications is about in developed countries and 1. Historically, there are conflicting opinions concerning the effect on the progression of tuberculosis during pregnancy. In the era before chemotherapy, pregnancy and the immediate postpartum period were associated with higher rates of active tuberculosis and faster progression of the disease.
Most studies in the era before chemotherapy fail to provide adequate comparison populations. Selection bias may have resulted in the inclusion of higher-risk women in the study groups. In the era of effective chemotherapy, there appears to be no difference in the progression of the disease or the cure rates when the results are controlled for risk factors and compliance.
However, tuberculosis remains a significant worldwide concern, obstetrically and economically. Among pregnant or postpartum women, tuberculosis annually kills more women worldwide than all other causes of maternal mortality combined. Children whose mothers die are 3 to 10 times more likely to die within 2 years than those with both parents alive. Tuberculosis often seems far removed from the obstetric care provider in the United States or Western Europe. The high levels of socioeconomic development and public health commitment have reduced the incidence of symptomatic tuberculosis dramatically.
In the mids, the rate of active tuberculosis in the United States was relatively constant at 10 cases per , persons.
One third of all persons with tuberculosis in the United States are middle- or upper-income individuals. The outbreaks of multidrug-resistant tuberculosis MDR-TB among health care workers 7 , 8 , 9 , 10 , 11 should raise significantly the obstetrician's caution and index of suspicion. A review of case reports suggests that approximately one of three exposed health care workers has a tuberculin skin test that converts. Active multidrug-resistant tuberculosis MDR-TB has been reported in more than 25 health care workers.
As a primary care provider for women of childbearing age, a commonly affected group, the obstetrician and gynecologist have a mandate to identify women at risk for tuberculosis or those with previous exposure.
Throughout the course of her therapy, a team of an internist infectious disease specialist , obstetrician, and public health nurse provide the support and education needed for compliance with her chemotherapy. Humans are the major reservoir for this species. These five organisms are the members of the M.
Other similar but distinct acid-fast Mycobacterium species can cause significant disease: Mycobacterium leprae leprosy , Mycobacterium avium M. Many other Mycobacterium species exist in soil, water, and animal reservoirs and only rarely are associated with human disease.
Mycobacterium species other than the M. Its generation time is 15 to 20 hours, compared with less than 1 hour for most common bacterial pathogens. Visible colonies require 3 to 4 weeks and appear as serpentine cording. The clinical impact of delay in identification is the decision whether to initiate chemotherapy and at what intensity.
Unfortunately, the decision to treat with three to four powerful antibiotics for 6 to 9 months may be made without the benefit of positive cultures and rest on the epidemiology and clinical presentation. In an effort to reduce the incidence of unnecessary treatment, an acid-fast stain is used to screen specimens.
In the classic Ziehl-Neelsen stain, a fixed smear covered with carbol fuchsin is heated, rinsed, decolorized with acid-alcohol, and counterstained with methylene blue. The Kinyoun stain is similar but modified to make the heating unnecessary. Many laboratories use a fluorochrome stain with phenolic auramine or auramine-rhodamine in the initial staining, a slightly modified acid-alcohol decolonization step, 13 and potassium permanganate counterstaining.
The mycobacteria fluoresce bright orange-yellow against a dark background with a strong blue light source. In sputum, they lie in parallel or adhere end to end to form a V shape. An estimated 10, organisms per milliliter of sputum are required for acid-fast stain positivity, and the identification of a single organism on the entire slide is highly suspicious.
Paucity of organisms dictates the acquisition of specimens with a high concentration of organisms and thorough examination of the prepared slides. At least three early morning before rising specimens are recommended.
Early morning gastric aspirates are effective if obtained before ambulation. Thin fluid i. The sample is then neutralized and centrifuged, and the sediment is inoculated into the media. Uncontaminated specimens i. Solid media is of two types, agar-based or egg-based, with suppressive additives for bacteria other than mycobacteria.
Radioactive palmitate is used as the sole carbon source in this liquid culture system. Within 9 to 16 days, metabolism is detected if M. Antibiotic sensitivity is determined by comparison of growth from appropriately diluted inocula on antibiotic-containing media solid or liquid to growth from on a antibiotic-free media. The use of polymerase chain reaction PCR in the diagnosis is rapidly changing the specific identification of M.
This technique can identify as few as 10 organisms in clinical specimens, compared with the 10, organisms necessary for AFB smear positivity, possibly within a day.
Although the PCR-based diagnosis is not widely available, in the near future, treatment without diagnosis will be an issue of the past. Traditional culture and sensitivity is still necessary, because PCR cannot detect antibiotic sensitivity. Worldwide, almost 1. Increasingly crowded living conditions and exposure to naive populations help explain these statistics.
In developing countries, the flight from rural areas to urban centers where inadequate infrastructure, including housing, jobs, and medical facilities, create urban ghettos. As tuberculosis is spread by airborne particles, these areas are a driving force in the epidemic. There is an element of increased susceptibility in the populations of the developing world. When the industrial revolution in Europe and the United States brought farmers into the overcrowded cities, one third of all adult deaths were associated with tuberculosis.
This selective pressure eliminated those who had the least resistance. During the 19th century, each new infectious case, those with primary, acute tuberculosis or cavitary lesions, infected 20 or more new individuals. In developed countries today, each case infects 13 or less new individuals.
These observations can be explained by changes in host resistance, better public health services, or decreased virulence of the organisms. The latter is less likely, given the epidemic seen in developing countries. In the past years, the epidemic has spread to those countries whose industrialization and urbanization is in process. The epidemic is fueled by crowded living and a large pool of naive humans.
In , the rate of tuberculosis cases in the United States leveled out with an excess of 39, cases occurring between and This change reflects the reduction in public support of tuberculosis control programs, the increases in at-risk populations i.
Changing this alarming trend remains a critical challenge for the U. Most tuberculosis in the United States is found in high-risk populations. These high-risk populations include health care workers, the urban poor, alcoholics, the homeless, intravenous drug abusers, migrant farm workers, and individuals who are chronically institutionalized e.
The worldwide, new case rates per , persons are depicted in Table 1. In the United States, two thirds of all new cases are minority individuals. TABLE 1. The rates of active tuberculosis among U. In the general population of developed countries, the most likely source of active tuberculosis is reactivation of remote disease in the elderly population. However, within high-risk U. Relatively asymptomatic HIV-infected patients can be infectious for tuberculosis without cavitary lesions.
Although tuberculosis can be transmitted by infected raw cow's milk M. The droplets are small enough to allow them to dry while airborne and become particles that remain suspended for long duration. A cough, sneezing, or talking for 5 minutes can produce infectious particles. The number of infectious particles required to produce infection is unknown, but it is likely that the risk of infection is inversely correlated with host defenses. For immunocompetent individuals, prolonged exposure to multiple aerosol inocula are needed for infection.
When the air environment is closed e. CD4 count of the patients. HIV infection, immunosuppressive drug therapy, steroids, and cancer chemotherapy. Isoniazid prophylaxis seems to prevent the progression. Aerosolized tuberculosis particles need to be small enough to be carried to the terminal air spaces, heavier droplets come into earlier contact with the bronchial mucociliary surface and are expectorated before infection occurs.
High-airflow areas, mid-lung regions i. Alveolar macrophages ingest the bacilli, and multiplication of the bacteria continues unimpeded. Blood-borne lymphocytes and macrophages begin to ingest the bacilli. The infected macrophages migrate to the regional lymph nodes usually hilar or mediastinal and form granulomatous lesions. During this phase, the bacilli disseminate to the corpus at an amount proportional to regional blood flow. Certain areas favor the continued multiplication of the bacilli: lymph nodes, posterior-apical lungs, meningeal areas, vertebral bodies, kidneys, and epiphysis of the long bones.
Until the development of tuberculin hypersensitivity, bacterial growth and tissue destruction continue. The speed at which the host develops the cellular hypersensitivity determines the survival of the bacilli and patient.
In the immunocompromised patient, the widely disseminated bacilli begin to multiply and destroy the local tissue. The incubation period for active tuberculosis has been reported to be as short as 20 days, and in most cases, it is 1 to 3 months.
Tuberculosis in Pregnancy
The disease is a significant contributor to maternal mortality and is among the three leading causes of death among women aged 15—45 years in high burden areas. The exact incidence of tuberculosis in pregnancy, though not readily available, is expected to be as high as in the general population. Diagnosis of tuberculosis in pregnancy may be challenging, as the symptoms may initially be ascribed to the pregnancy, and the normal weight gain in pregnancy may temporarily mask the associated weight loss.
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.
Treating TB Infection During Pregnancy
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. In , 9 million people around the world became infected with TB, and there were approximately 1. TB is a leading killer of people who are HIV infected. A total of 11, TB cases a rate of 3. Both the number of reported TB cases and the case rate have decreased; there was a 3.

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.
Tuberculosis in Pregnancy: A Review
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.
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.
