Medical and obstetric outcomes among pregnant women with tuberculosis: a population-based study of 7.8 million births

Tuberculosis in pregnancy and assisted reproductive technology

Tuberculosis is a chronic infectious disease caused by mycobacterium tuberculosis infection. In the world, tuberculosis is an important factor affecting women's reproductive health, which can cause reproductive tract anatomy abnormalities, embryo implantation obstacles, ovarian reserve and ovulation dysfunction, leading to female infertility. This group of women usually need to seek assisted reproductive technology to conceive. Latent tuberculosis infection during pregnancy has no clinical manifestation, but may develop into active tuberculosis, leading to adverse pregnancy outcomes. Most pregnant women do not need to be treated for latent tuberculosis infection, unless they are combined with high-risk factors for tuberculosis progress, but they need close follow-up. Early diagnosis and treatment of active tuberculosis in pregnancy can reduce the incidence rate and mortality of pregnant women and newborns, and treatment needs multidisciplinary cooperation.

Tuberculosis in pregnancy and adverse neonatal outcomes in two peruvian hospitals

Background

According to the World Health Organization, tuberculosis (TB) ranks among the top 10 causes of death worldwide. The significance of TB during pregnancy lies in its symptoms, which can be mistaken for physiological changes associated with pregnancy. This confusion can lead to maternal-perinatal complications.

Objective

To evaluate the association between pulmonary TB in pregnancy and adverse neonatal outcomes in two Peruvian hospitals.

Methods

This is a retrospective cohort study. The target population consisted of pregnant women with and without pulmonary TB whose deliveries were attended at two public hospitals, located in Lima, Peru. The adverse neonatal outcomes were prematurity, low birth weight (LBW), and being small for gestational age (SGA). Crude and adjusted relative risks (RRa) were calculated with their respective 95% confidence intervals (95%CI).

Results

Information from 212 patients was analyzed; 48.1% had TB during pregnancy, and 23.1% had adverse neonatal outcomes (8%, 11.3%, and 12.3% for LBW, prematurity, and SGA, respectively). In the adjusted model, pregnant women with pulmonary TB had a 3.52 times higher risk of having a newborn with at least one of the adverse outcomes than those who were not exposed (aRR, 3.52; 95%CI: 1.93-6.68).

Conclusion

Pulmonary TB in pregnancy was jointly and independently associated with adverse neonatal outcomes, including LBW, prematurity, and being SGA.

Systemic inflammation, enteropathogenic E. Coli, and micronutrient insufficiencies in the first trimester as possible predictors of preterm birth in rural Bangladesh: a prospective study

BACKGROUND

An incomplete understanding of preterm birth is especially concerning for low-middle income countries, where preterm birth has poorer prognoses. While systemic proinflammatory processes are a reportedly normal component of gestation, excessive inflammation has been demonstrated as a risk factor for preterm birth. There is minimal research on the impact of excessive maternal inflammation in the first trimester on the risk of preterm birth in low-middle income countries specifically.

METHODS

Pregnant women were enrolled at the rural Bangladesh site of the National Institute of Child Health Global Network Maternal Newborn Health Registry. Serum samples were collected to measure concentrations of the inflammatory markers C-reactive protein (CRP) and Alpha-1-acid glycoprotein (AGP), and stool samples were collected and analyzed for enteropathogens. We examined associations of maternal markers in the first-trimester with preterm birth using logistic regression models. CRP and AGP were primarily modeled with a composite inflammation predictor.

RESULTS

Out of 376 singleton births analyzed, 12.5% were preterm. First trimester inflammation was observed in 58.8% of all births, and was significantly associated with increased odds of preterm birth (adjusted odds ratio [aOR] = 2.23; 95% confidence interval [CI]: 1.03, 5.16), independent of anemia. Maternal vitamin B12 insufficiency (aOR = 3.33; 95% CI: 1.29, 8.21) and maternal anemia (aOR = 2.56; 95% CI: 1.26, 5.17) were also associated with higher odds of preterm birth. Atypical enteropathogenic E. coli detection showed a significant association with elevated AGP levels and was significantly associated with preterm birth (odds ratio [OR] = 2.36; 95% CI: 1.21, 4.57), but not associated with CRP.

CONCLUSIONS

Inflammation, anemia, and vitamin B12 insufficiency in the first trimester were significantly associated with preterm birth in our cohort from rural Bangladesh. Inflammation and anemia were independent predictors of premature birth in this low-middle income setting where inflammation during gestation was widespread. Further research is needed to identify if infections such as enteropathogenic E. coli are a cause of inflammation in the first trimester, and if intervention for infection would decrease preterm birth.

Analysis of prevalence of adverse events connected with anti-tuberculosis drugs during pregnancy: A meta-analysis

Background

Mycobacterium tuberculosis infection is transmitted among humans via airborne droplets. The drugs used in the initial treatment regimen for tuberculosis (TB) cross the placenta, raising some concerns regarding their safety during pregnancy may provide a more valid approach for evaluating the relative influence of various risk factors. Adverse events of anti-tuberculous (anti-TB) drug during pregnancy remain uncertain and controversial issues.

Methods

We performed a systematic analysis to study the adverse events connected with anti-TB drugs usage during pregnancy. The risk of bias in the included studies was assessed using the Cochrane Collaboration criteria. Interstudy heterogeneity was assessed via Cochran's test. Assuming heterogeneity, a random-effects model was applied. Outcomes were pooled using the inverse variance method. Besides, a funnel plot was created to assess publication bias. We used Egger's linear regression test of funnel plot asymmetry, modified to accommodate inter-study heterogeneity. Effect estimates and confidence intervals for all studies were depicted on a forest plot.

Results

The prevalence of total adverse events for all anti-TB drugs was 25.9 %. According to the drug category, the prevalence of total adverse events was 50 % for ethambutol, 32.6 % for the six-month directly observed treatment short-course (DOTS), 31.4 % for the nine-month DOTS, and 13.7 % for isoniazid.

Conclusions

There is a high rate of reported adverse events associated with anti-TB drugs usage during pregnancy. We concluded that more high-quality clinical studies and research works are needed to reach a conclusive decision on the safety of the treatment of TB among pregnant women.

HIV/Tuberculosis Coinfection in Pregnancy and the Postpartum Period

The convergence of Human Immunodeficiency Virus (HIV) and tuberculosis (TB) represents a considerable global public health challenge. The concurrent infection of HIV and TB in pregnant women not only intensifies the transmission of HIV from mother to fetus but also engenders adverse outcomes for maternal health, pregnancy, and infant well-being, necessitating the implementation of integrated strategies to effectively address and manage both diseases. In this article, we review the pathophysiology, clinical presentation, treatment, and management of HIV/TB coinfection during pregnancy, the postpartum period, and lactation and highlight the differences compared to the general population.

Reactivated disseminated tuberculosis in pregnancy: Case report and review of the literature

This case report describes the evaluation and management of a 32-year-old woman who presented shortly after a fetal demise at 23 weeks of gestation with multiple symptoms, including bloody vaginal discharge. Although the initial diagnostic concern was for metastatic malignancy, the patient was ultimately determined to have disseminated tuberculosis. Genital tuberculosis is common worldwide, yet guidelines for evaluation are limited. This report highlights the relationship between pregnancy-reactivated tuberculosis, and guides clinicians on diagnostic and management considerations in the peripartum period.

Tuberculosis in pregnancy

Due to COVID-19 pandemic, the latest progress of the End Tuberculosis (TB) Strategy was far from optimal and services for TB needs to be quickly restored. Pregnancy is a unique opportunity to screen and manage TB, and it is an essential step in TB eradication. Early diagnosis and treatment for active disease can reduce maternal and neonatal morbidities and mortality. The more widespread utilization of newer rapid molecular assays with drug-susceptibility testing has significantly shortened the diagnostic process for active TB disease. First-line anti-TB drugs are proven to be safe in pregnancy. Management of latent TB infection (LTBI) during pregnancy is controversial, but puerperium is a period of increased susceptibility to progress to active disease. Extrapulmonary TB (EPTB), multidrug-resistant TB (MDR-TB) and HIV co-infection remain significant issues surrounding TB management during pregnancy and often require input from a multidisciplinary team including TB experts.

Clinical characteristics in 26 children with congenital tuberculosis in Central Southern China: a retrospective study

BACKGROUND

Congenital tuberculosis (CTB) is relatively rare and most patients are described in case reports.

AIM

To investigate the clinical characteristics of CTB in 26 children.

METHODS

A retrospective analysis of 26 children with CTB from January 2013 to December 2021 in Changsha Central Hospital in Central Southern China was undertaken.

RESULTS

The median age at onset was 25 days (17-33) and within 4 weeks of age in approximately 73% of cases. Of 24 mothers (including two mothers of twins), 18 (75.0%) were asymptomatic during pregnancy, and four were diagnosed with tuberculosis prenatally. The numbers of tuberculous meningitis, tuberculous encephalitis and liver TB were 17 (65.4%), five (19.2%) and four (15.4%), respectively. The main symptoms were fever (n = 18, 69.2%) and cough (n = 16, 61.5%). Positive rates of T-SPOT.TB, acid-fast bacilli smear, culture of Mycobacterium tuberculosis and GeneXpert MTB/RIF test were, respectively, 84.2% (16/19), 42.3% (11/26), 43.5% (10/23) and 83.3% (5/6). Radiograph or computed tomography demonstrated typical pulmonary tuberculous lesions in all cases and the head magnetic resonance imaging (MRI) showed marked meningeal enhancement or parenchymal lesions in seven cases (26.9%). One case had drug-resistant TB. During follow-up, nine cases had varying degrees of liver injury, and one had delayed growth and development. Eight died and 18 recovered satisfactorily.

CONCLUSION

Maternal TB status during pregnancy, the epidemiological history, T-SPOT.TB and other TB-related aetiological tests and imaging are important for the early diagnosis and treatment of CTB, and are associated with a favourable outcome.

Obstetrics outcome in pulmonary tuberculosis

BACKGROUND

To evaluate the maternal and perinatal outcome in pulmonary tuberculosis cases as compared to low risk pregnancies in a tertiary referral hospital.

METHODS

A total of 15 cases of pulmonary tuberculosis over a period of two years who delivered in our unit was studied in the retrospective study. The maternal and perinatal outcome in them was compared with 191 low risk pregnancies who delivered at the same time in the hospital after taking into account inclusion and exclusion criteria.

RESULTS

The mean age and mean parity was 25.73 ± 2.85 and 28.75 ± 3.11, 2.1 and 1.9 in the 2 groups. Symptoms of pulmonary tuberculosis were cough (100%), chest pain (80%), expectoration (100%), hemoptysis (33.3%), fever (93.33%), anorexia (86.66%) and loss of weight (80%). Symptoms in study patients were significantly more common in study patients. The presence of associated medical problems was similar in the 2 groups. The prevalence of oligoamnios, gestational diabetes mellitus, antepartum hemorrhage and intrahepatic cholestasis was similar in the 2 groups. Prevalence of preterm labor was 53.33% in study group which was significantly higher than in controls (8.9%). Risk of premature rupture of membrane was also significantly higher in the study groups (53.33%) as compared to control groups (8.9%). Mean gestational age was also significantly lower (36.2 weeks) in study group as compared to 38.6 weeks in control group. The incidence of cesarean delivery was similar in the 2 groups (26.66% vs 28.79%). The mean birth weights was 2308.6 gm in the study group as compared to 2707.56 gm in control group. Fetal growth restrictions and Respiratory distress syndrome in babies was significantly higher in study group than in control group. Low APGAR score (<8) was also higher (33.3%) in study group as compared to control group (2.61%).

CONCLUSION

Pulmonary tuberculosis during pregnancy is associated with increased perinatal morbidity, low birth weight, poor APGAR and increased respiratory distress rates.

Tuberculosis infection and stillbirth in Ethiopia—A prospective cohort study

Background

Tuberculosis is among the leading causes of death among infectious diseases. Regions with a high incidence of tuberculosis, such as sub-Saharan Africa, are disproportionately burdened by stillbirth and other pregnancy complications. Active tuberculosis increases the risk of pregnancy complications, but the association between latent tuberculosis infection (LTBI) and pregnancy outcomes is unknown. We explored the effect of latent tuberculosis infection on the risk of stillbirth in women attending antenatal care clinics in Ethiopia, a country with >170 000 annual cases of active tuberculosis.

Method

Pregnant women were enrolled from antenatal care at three health facilities in Adama, Ethiopia, during 2015–2018, with assessment for previous and current active tuberculosis and testing for LTBI using QuantiFERON-TB-GOLD-PLUS. Proportions of stillbirth (≥ 20 weeks of gestation) and neonatal death (< 29 days of birth) were compared with respect to categories of maternal tuberculosis infection (tuberculosis-uninfected, LTBI, previous-, and current active tuberculosis). Multivariable logistic regression was performed for stillbirth.

Results

Among 1463 participants enrolled, the median age was 25 years, 10.2% were HIV-positive, 34.6% were primigravidae, and the median gestational age at inclusion was 18 weeks. Four (0.3%) were diagnosed with active tuberculosis during pregnancy, 68 (4.6%) reported previous treatment for active tuberculosis, 470 (32.1%) had LTBI, and 921 (63.0%) were tuberculosis-uninfected. Stillbirth was more frequent in participants with LTBI compared to tuberculosis-uninfected participants, although not reaching statistical significance (19/470, 4.0% vs 25/921, 2.7%, adjusted [for age, gravidity and HIV serostatus] odds ratio 1.38, 95% confidence interval 0.73–2.57, p = 0.30). Rates of neonatal death (5/470, 1.1% vs 10/921, 1.1%) were similar between these categories.

Conclusion

Latent tuberculosis infection was not significantly associated with stillbirth or neonatal death in this cohort. Studies based on larger cohorts and with details on causes of stillbirth, as well as other pregnancy outcomes, are needed to further investigate this issue.

Examining family planning and adverse pregnancy outcomes for women with active tuberculosis disease: a systematic review

OBJECTIVES

(1) Summarise and evaluate the current evidence of tuberculosis (TB)-associated pregnancy outcomes, (2) evaluate the state of the science of family planning during TB treatment and (3) provide recommendations to move forward to improve care and outcomes during TB disease.

DESIGN

Systematic review using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines.

DATA SOURCES

PubMed, Embase, CINAHL, Cochrane, Web of Science and Scopus were searched from September 2009 to November 2021.

ELIGIBILITY CRITERIA

Studies were included if they assessed pregnant women with active TB, drug-resistant TB (DR-TB) or TB/HIV coinfection and examined pregnancy, maternal, fetal/birth and TB or TB/HIV coinfection outcomes. Studies were also included if they examined family planning services among women initiating TB treatment.

DATA EXTRACTION AND SYNTHESIS

Two independent reviewers extracted data using PRISMA guidelines and conducted quality assessment using the Joanna-Briggs Institute Critical Appraisal Tools. The level of evidence was reported using the Johns Hopkins Evidence-Based Practice guidelines.

RESULTS

69 studies were included in this review. Case reports, case series, case controls, cohort studies, secondary data analyses and a service delivery improvement project conducted in 26 countries made up the totality of the evidence. Most studies reported pregnancy complications for mothers (anaemia, postpartum haemorrhage, deaths) and fetuses or newborns (low birth weight, premature birth, and spontaneous or induced abortions). Few studies discussed the value of offering family planning to prevent adverse pregnancy outcomes. One study examined the effect of a provider training on contraceptive use with reported increased contraceptive use.

CONCLUSIONS

Integrating family planning services within a TB treatment programme is essential to reduce adverse TB-associated maternal-child outcomes. Despite well-established adverse pregnancy outcomes, little attention has been paid to family planning to prevent poor pregnancy outcomes for women with TB/DR-TB. Recommendations for clinicians, TB programmes and researchers are provided and reflect evidence presented in this review.

Pregnancy and post-partum tuberculosis; a nationwide register-based case-control study, Denmark, 1990 to 2018

Background

Pregnancy increases the risk of tuberculosis (TB), however, data on TB epidemiology in pregnant women are limited.

Aim

To guide possible interventions, we analysed risk factors for TB in pregnant and post-partum women.

Methods

We conducted a nationwide retrospective register-based case–control study from January 1990 to December 2018 in Denmark. Cases were women diagnosed with TB during their pregnancy or in the post-partum period. We selected two control groups: pregnant or post-partum women without TB, and non-pregnant women with TB. Differences were assessed by chi-squared or Fisher’s exact test. Risk factors for TB were identified through logistic regression and estimated by odds ratio (OR).

Results

We identified 392 cases, including 286 pregnant and 106 post-partum women. Most were migrants (n = 366; 93%) with a shorter median time spent in Denmark (2.74 years; interquartile range (IQR): 1.52–4.64) than non-pregnant TB controls (3.98 years; IQR: 1.43–8.51). Cases less likely had a Charlson comorbidity index ≥ 2compared with non-pregnant TB controls (p < 0.0001), and had no increased risk of severe disease (p = 0.847). Migrants from other World Health Organization regions than Europe, especially Africa (OR: 187; 95%CI: 125–281) had persistently higher odds of TB.

Conclusions

In Denmark, the risk of TB in pregnant and post-partum women is increased in migrant women who have stayed in the country a median time of approximately 3 years. We recommend increased focus on TB risk during pregnancy and suggest evaluating targeted TB screening of selected at-risk pregnant women to promote early case finding and prevent TB among mothers and their newborn children.

Less common bacterial, fungal and viral infections: review of management in the pregnant patient

This review is a comprehensive summary of treatment options for pregnant patients with less common bacterial, fungal, and viral infections. It offers guidance to clinicians based on the most recently published evidence-based research and expert recommendations. A search of MEDLINE (inception to March 2021) and the CDC website was performed. Liposomal amphotericin B is the preferred therapy for cryptococcosis, histoplasmosis, oesophageal candidiasis, and coccidioidomycosis, especially during the first trimester due to teratogenic concerns with azole antifungals. For oral candidiasis, clotrimazole troches or miconazole mucoadhesive buccal tablets are recommended. A β-lactam antimicrobial is preferred over doxycycline for various manifestations of Lyme disease and the drug of choice for Pneumocystis pneumonia is trimethoprim/sulfamethoxazole. Acyclovir is the preferred antiviral for varicella zoster virus. Fluoroquinolones, macrolides, and aminoglycosides should be avoided if possible and there are alternate agents available for an effective treatment regimen. There is a scarcity of clinical data in pregnant patients with less common bacterial, fungal and viral infections. This population lacks definitive recommendations in many clinical practice guidelines. The key to optimizing therapy is a comprehensive review of the available evidence and a careful balance of risks and benefits before final treatment decisions.

Increased Risk of Stillbirth among Women whose Partner Has Tuberculosis

BACKGROUND

The relationship between tuberculosis (TB) and adverse pregnancy outcomes remains unclear. The aim of our study was to investigate whether TB is a risk factor for adverse pregnancy outcomes including premature birth, low birth weight, and stillbirth.

METHOD

We conducted a population-based retrospective cohort study in mainland China. A total of 3,668,004 Chinese women, along with their partners, were included in this study, within the National Free Pre-Pregnancy Checkups Project, during 2015-2018. Propensity score matching was used to balance the two groups (cases: women or partners with TB; controls: women and partners without TB). Multivariable logistic regression was used to estimate odds ratios (ORs) and 95% confidence intervals (CIs).

RESULTS

Multivariate logistic regression showed that the OR of stillbirth for cases was 1.89 (95% CI: 1.09-3.16), in comparison with the control group. In the subgroup analysis, women whose partner had TB had a higher risk of stillbirth (OR: 2.13, 95% CI: 1.10-3.86) than women whose partner did not have TB. There was no significant difference in adverse pregnancy outcomes, including preterm birth, low birth weight, and stillbirth, between women with and without TB.

CONCLUSIONS

Women whose partner had TB were more likely to have stillbirth than women whose partners did not have TB.

Audit of Early and Late Maternal Deaths in Georgia: Potential for Improving Substandard Obstetric Care

Introduction

Quality of care is an important factor in reducing preventable maternal deaths, yet it is a significant challenge in many countries. Substandard and poor quality of care is the leading factor in two-thirds of maternal deaths in European countries. Our study investigated the deaths of all women of reproductive age in 2012 in Georgia. The aim was to define the underlying causes of maternal deaths and to identify the factors in women’s care which contributed to the fatal outcomes.

Methods

A national Reproductive Age Mortality Survey was conducted in Georgia in 2014–15. Data from multiple sources was triangulated to identify all deaths of women of reproductive age. This was followed by verbal autopsy diagnoses. Each case of early and late maternal death was investigated through interviews and medical record reviews at the last medical facility providing care for the deceased woman. A specialist panel reviewed and assigned underlying causes of death, assessed the management of each woman’s condition, and identified elements of suboptimal care.

Results

We identified a total of 23 maternal deaths, including 15 (65%) early and eight (35%) late deaths. The maternal mortality ratio was 26.3 per 100 000 live births. The four leading causes of early maternal deaths were: sepsis, hemorrhage, embolism, and pregnancy-induced hypertension. Embolism and sepsis were the direct causes of the eight late maternal deaths. Cancer, tuberculosis, and postpartum suicide constituted the indirect causes of death. Improvements in care which would have made a difference to the outcomes were identified in 87% of early maternal deaths and 67% of late maternal deaths due to direct obstetric causes.

Discussion

Delayed recognition and inappropriate management of maternal complications were common across almost all cases studied. The findings from Georgia highlight the conclusion that most maternal deaths were preventable and that improvement in obstetric care is urgently required.

An Unfortunate Case of Reactivation of Tuberculosis in a Postpartum Female

Tuberculosis (TB) is a widely prevalent disease, especially in resource-limited settings. It poses a big burden to the community and is a significant cause of morbidity and mortality in pregnant females due to their immunosuppressed state. During pregnancy, the immune system is suppressed to prevent fetal rejection, and it gets reconstituted postpartum. During this reconstitution phase, reactivation of TB may occur, making it quintessential to test peripartum females for latent TB, especially those belonging to endemic regions. We describe an unfortunate case of reactivation of TB in a postpartum female from Central America.

Prophylaxis for Tuberculosis in Pregnant Women

As more women at increased risk for tuberculosis (TB) reactivation immigrate to the United States, perinatal screening and chemoprophylaxis are increasingly important. Interferon-gamma release assays and the tuberculin skin test are acceptable screening tests with the latter supported by more data in pregnancy. Women screening positive should have active TB excluded, and if negative, latent TB is likely. Prophylaxis should be deferred until 3 months postpartum except in those severely immunosuppressed, human immunodeficiency virus positive, or recently exposed. Isoniazid with pyridoxine for 9 months is preferred with reasonable safety in pregnancy and breastfeeding. Monitoring for maternal hepatotoxicity is recommended.

Perinatal Outcome and Long-Term Infectious Morbidity of Offspring Born to Women with Known Tuberculosis

Objective: To evaluate the perinatal outcome of women with tuberculosis and to assess a possible association between maternal tuberculosis and long-term infectious morbidity of the offspring. Study design: Perinatal outcome and long-term infectious morbidity of offspring of mothers with and without tuberculosis were assessed. The study groups were followed until 18 years of age tracking infectious-related morbidity and infectious-related hospitalizations and then compared. For perinatal outcome, generalized estimation equation models were used. A Kaplan-Meier survival curve was used to compare cumulative incidence of long-term infectious morbidity. A Cox proportional hazards model was conducted to control for confounders. Results: During the study period, 243,682 deliveries were included, of which 46 (0.018%) occurred in women with tuberculosis. Maternal tuberculosis was found to be independently associated with placental abruption, cesarean deliveries, and very low birth weight. However, offspring born to mothers with tuberculosis did not demonstrate higher rates of infectious-related morbidity. Maternal tuberculosis was not noted as an independent risk factor for long-term infectious morbidity of the offspring. Conclusion: In our study, maternal tuberculosis was found to be independently associated with adverse perinatal outcomes. However, higher risk for long-term infectious morbidity of the offspring was not demonstrated. Careful surveillance of these women is required.

Impact of human immunodeficiency virus, malaria, and tuberculosis on adverse pregnancy outcomes in the United States

OBJECTIVE

To compare rates of adverse pregnancy outcomes for HIV, tuberculosis, and malaria-infected patients in the United States with those of uninfected patients.

STUDY DESIGN

A nationally representative sample of 24,149,664 singleton live births were identified using pregnancy hospitalizations that resulted in delivery between 1998-2000 and 2009-2011 in this retrospective cohort study. Maternal and fetal outcomes were evaluated.

RESULTS

There were 7204 HIV cases, 1450 TB cases, and 296 malaria cases over the two time periods, and the average age of infected subjects was 28.3. The HIV group was more likely to have almost all adverse pregnancy outcomes than the control group in both time periods. The 2009-2011 HIV group was more likely to undergo cesarean delivery than the 1998-2000 HIV group [1959 versus 1649, p < 0.0001].

CONCLUSION

Out of pregnant women infected with HIV, malaria, or tuberculosis, those infected with HIV are more likely to experience several adverse pregnancy outcomes than uninfected women.

Neurologic infections during pregnancy

Neurologic infections during pregnancy represent a significant cause of maternal and fetal morbidity and mortality. Immunologic alterations during pregnancy increase the susceptibility of the premature brain to damage. This chapter summarizes the epidemiology, pathophysiology, and clinical manifestations in the pregnant woman and the infant, and the diagnosis, treatment, and prevention of the major viral, parasitic, and bacterial infections known to affect pregnancy. These organisms include herpes virus, parvovirus, cytomegalovirus, varicella, rubella, Zika virus, toxoplasmosis, malaria, group B streptococcus, listeriosis, syphilis, and tuberculosis. There is an emphasis on the important differences in diagnosis, treatment, and fetal outcome between trimesters. An additional overview is provided on the spectrum of neurologic sequelae of an affected infant, which ranges from developmental delay to hydrocephalus and seizures.

Disseminated hematogenous tuberculosis in puerperium-case report

Although tuberculosis (TB) is relatively common in pregnancy and puerperium, its disseminated form is a rare event, with potential lethal maternal and fetal outcomes. Due to the infrequency and lack of knowledge of most physicians about the various manifestations of the disease, the diagnosis is often overlooked, and treatment postponed, resulting in a high death rate. We report a fatal case of disseminated tuberculosis in the puerperium, with lung, brain, liver and uterine involvement. After, we briefly review the clinical manifestations of TB in the gestational period.

Retrospective Analysis of 28 Cases of Tuberculosis in Pregnant Women in China

While tuberculosis (TB) in pregnant women is reported globally, clinical data is unavailable in China. To describe clinical features and identify difficulties in the diagnosis of pregnancy-related TB, we performed a retrospective study of 28 TB inpatients at Beijing Chest Hospital. The results were presented in terms of interquartile range (IQR) for age, and medians and percentages with respect to the categorical variables. One patient (3.6%) was immediately diagnosed; for 27 patients (96.4%), the median interval from the initial onset of symptoms to diagnosis was five weeks. Eight cases (28.6%) were microbiologically confirmed. 22 (78.6%) were pulmonary TB (PTB), while six (21.4%) were extrapulmonary TB (EPTB). In addition, eight (28.6%) were miliary TB and six (21.4%) were cerebral TB. 27 (96.4%) were cured and one (3.6%) died. 15 neonates were identified, nine of which were healthy. Two were small for the gestational age (SGA) and one was a stillbirth. Three had neonatal TB, one of which died. Nine were legal abortions and four were spontaneous abortions. Indeed, there was a substantial delay in the diagnosis of TB in the pregnant women and a high incidence of both miliary and cerebral TB was evident. With timely treatment, prognosis is positive.

Congenital Tuberculosis: A New Concern in the Neonatal Intensive Care Unit

BACKGROUND

Congenital tuberculosis (TB) is rare in the United States. Recent immigration patterns to the United States have made the diagnosis of congenital TB an important public health issue.

PURPOSE

To explore the epidemiology, pathophysiology, diagnostic evaluation, treatment, and prognosis for congenital TB. The implications for exposed healthcare professionals in the neonatal intensive care unit (NICU) setting are also explored.

METHODS/SEARCH STRATEGY

Relevant articles were accessed via PubMed, CINAHL, and Google Scholar.

FINDINGS/RESULTS

Until 1994, fewer than 400 cases of confirmed congenital TB had been reported in the literature worldwide. An additional 18 cases were reported from 2001 to 2005. Neonatal providers need to be aware of the potential for congenital TB infection as the immigrant population in the United States continues to increase, many of whom originate from TB endemic countries.

IMPLICATIONS FOR PRACTICE

The interpretation of TB-specific tests is problematic in newborns due to decreased sensitivity and specificity. Congenital TB should be ruled out in infants with signs and symptoms of sepsis or pneumonia and in whom broad-spectrum antibiotic therapy does not improve their clinical status.

IMPLICATIONS FOR RESEARCH

The interpretation of TB-specific tests is problematic in newborns due to decreased sensitivity and specificity; more research is needed regarding best practice in diagnosis. Established protocols are needed to address the healthcare of TB-exposed providers in the NICU.

Hospital length of stay and cost burden of HIV, tuberculosis, and HIV-tuberculosis coinfection among pregnant women in the United States

BACKGROUND

We sought to determine hospital length of stay (LOS) and cost burden associated with hospital admissions among pregnant women with HIV monoinfection, tuberculosis (TB) monoinfection, or HIV-TB coinfection in the United States.

METHODS

Analysis covered the period from 2002-2014 using data from the Nationwide Inpatient Sample. Relevant ICD-9-CM codes were used to determine HIV and TB status. Costs associated with hospitalization were calculated and adjusted to 2010 dollars using the medical care component of the Consumer Price Index.

RESULTS

We found modest annual average reduction in HIV, TB, and HIV-TB coinfection rates over the study period. The mean LOS was lowest among mothers free of HIV or TB disease and highest among those with HIV-TB coinfection. The average LOS among mothers diagnosed with TB monoinfection was 60% higher than for those with HIV monoinfection. The cost associated with pregnancy-related hospital admissions among mothers with HIV was approximately 30% higher than disease-free mothers, and the cost more than doubled among patients with TB monoinfection or HIV-TB coinfection.

CONCLUSIONS

TB significantly increased hospital care cost among HIV-positive and HIV-negative pregnant women.

Tuberculosis during pregnancy in the United States: Racial/ethnic disparities in pregnancy complications and in-hospital death

Background

Despite decades of efforts to eliminate tuberculosis (TB) in the United States (US), TB still contributes to adverse ill health, especially among racial/ethnic minorities. According to the Centers for Disease Control and Prevention, in 2016, about 87% of the TB cases reported in the US were among racial and ethnic minorities. The objective of this study is to explore the risks for pregnancy complications and in-hospital death among mothers diagnosed with TB across racial/ethnic groups in the US.

Methods

This retrospective cohort study utilized National Inpatient Sample data for all inpatient hospital discharges in the US. We analyzed pregnancy-related hospitalizations and births in the US from January 1, 2002 through December 31, 2014 (n = 57,393,459). Multivariable logistic regression was applied to generate odds ratios for the association between TB status and the primary study outcomes (i.e., pregnancy complications and in-hospital death) across racial/ethnic categories.

Results

The prevalence of TB was 7.1 per 100,000 pregnancy-related hospitalizations. The overall prevalence of pregnancy complications was 80% greater among TB-infected mothers than their uninfected counterparts. Severe pre-eclampsia, eclampsia, placenta previa, post-partum hemorrhage, sepsis and anemia occurred with greater frequency among mothers with a TB diagnosis than those without TB, irrespective of race/ethnicity. The rate of in-hospital death among TB patients was 37 times greater among TB-infected than in non-TB infected mothers (468.8 per 100,000 versus 12.6 per 100,000). A 3-fold increased risk of in-hospital death was observed among black TB-negative mothers compared to their white counterparts. No racial/ethnic disparities in maternal morbidity or in-hospital death were found among mothers with TB disease.

Conclusion

TB continues to be an important cause of morbidity and mortality among pregnant women in the US. Resources to address TB disease should also target pregnant women, especially racial/ethnic minorities who bear the greatest burden of the disease.

HIV-TB Coinfection among 57 Million Pregnant Women, Obstetric Complications, Alcohol Use, Drug Abuse, and Depression

Objective

HIV and tuberculosis represent diseases of major public health importance worldwide. Very little is known about HIV-TB coinfection among pregnant women, especially from industrialized settings. In this study, we examined the association between TB, HIV, and HIV-TB coinfection among pregnant mothers and obstetric complications, alcohol use, drug abuse, and depression.

Method

We examined inpatient hospital discharges in the United States from January 1, 2002, through December 31, 2014. We employed multivariable survey logistic regression to generate adjusted estimates for the association between infection status and study outcomes.

Results

We analyzed approximately 57 million records of pregnant women and their delivery information. HIV-TB coinfection was associated with the highest risks for several obstetric complications, alcohol use, and drug abuse. The risk for alcohol abuse was more than twice as high among HIV-monoinfected as compared to TB-monoinfected mothers. That risk gap more than doubled with HIV-TB coinfection. Both HIV-monoinfected and HIV-TB coinfected mothers experienced similarly increased risks for depression.

Conclusions

Mothers with HIV-TB coinfection experienced relatively heightened risks for obstetric complications, alcohol use, and drug abuse. The findings of this study underscore the importance of augmenting and enhancing social and structural support systems for HIV-TB coinfected pregnant women.
