Pregnancy outcome following gestational exposure to fluoroquinolones: a multicenter prospective controlled study

[Pneumonia and pregnancy]

Acute community-acquired pneumonia (CAP) during pregnancy is a frequently encountered and potentially severe condition. CAP incidence and ecology are unchanged during pregnancy as compared with the overall young adult population. Risk factors specifically identified in pregnant women include advanced gestational age, asthma, anemia and repeated courses of corticosteroid therapy for fetal lung maturation. The clinical presentation of CAP is not altered during pregnancy. Key points in the pregnant host encompass: (i) reduced maternal tolerance to hypoxia, due to physiological adaptations during pregnancy; (ii) heightened severity of some infections, notably viral pneumonias such as influenza, varicella or SARS-CoV-2 pneumonia; (iii) potentially deleterious fetal repercussions of infection and maternal hypoxia, with an increased risk of premature delivery and prematurity; (iv) the need for specific attention to the risk of fetal irradiation in the performance of possibly repeated radiological examinations and (v) therapeutic specificities arising from the possible embryo-fetal toxicity of certain anti-infectious agents. CAP prevention is premised on compliance with universal hygiene measures and on vaccination, which guarantees protection against severe forms of pneumonia not only in the mother (Streptococcus pneumoniae, seasonal flu, chickenpox, COVID-19), but also in the child during the first few months of life (whooping cough, RSV).

The association between prenatal antibiotic exposure and adverse long-term health outcomes in children: A systematic review and meta-analysis

BACKGROUND

Antibiotics are the most commonly prescribed drugs during pregnancy. The long-term health risks to children associated with prenatal antibiotic exposure are uncertain.

OBJECTIVE

To identify the association between prenatal antibiotics and adverse long-term health outcomes in children.

METHODS

A systematic search was done to identify original studies investigating the association between prenatal antibiotic exposure and adverse long-term health outcomes in children. Studies were excluded if: (i) antibiotics were only given during delivery or (ii) the outcome was present before antibiotic exposure.

RESULTS

We included 158 studies, reporting 23 outcomes in 21,943,763 children, in our analysis. For the following adverse health outcomes, there was a significant association with antibiotic exposure found in two or more studies: atopic dermatitis (OR 1.27, 95% CI 1.06-1.52, p=0.01), food allergies (OR 1.25, 95% CI 1.09-1.44, p<0.01), allergic rhinoconjunctivitis (OR 1.16, 95% CI 1.15-1.17, p<0.01), wheezing (OR 1.39, 95% CI 1.14-1.69, p<0.01), asthma (OR 1.36, 95% CI 1.24-1.50, p<0.01), obesity (OR 1.36, 95% CI 1.12-1.64, p<0.01), cerebral palsy (OR 1.25, 95% CI 1.10-1.43, p<0.01), epilepsy or febrile seizure (OR 1.16, 95% CI 1.08-1.24, p<0.01), and cancer (OR 1.13, 95% CI 1.01-1.26, p=0.04).

CONCLUSION

Although causality cannot be implied, these findings support antibiotic stewardship efforts to ensure judicious use of antibiotics during pregnancy to avoid potential long-term health risks.

Pregnancy related adverse events and congenital disorders associated with fluoroquinolones: A real-world pharmacovigilance study of the FDA adverse event reporting system (FAERS)

Background

Fluoroquinolones, including ciprofloxacin, levofloxacin, and moxifloxacin, are extensively employed as broad-spectrum antibacterial agents. However, their use is discouraged during pregnancy due to potential adverse events (AEs). The aim of this study is to systematically investigate the association between fluoroquinolones (specifically ciprofloxacin, levofloxacin, and moxifloxacin) and AEs related to pregnancy, as well as their potential impact on congenital disorders.

Methods

A disproportionality analysis was conducted utilizing FDA Adverse Event Reporting System (FAERS) data spanning from the first quarter of 2004 to September 2023. The objective was to identify potential AEs signatures associated with fluoroquinolones through conducting reporting odds ratios (RORs) and Bayesian confidence propagation neural networks (BCPNN). Assessing the potential risk of pregnancy-associated AEs involved comparing each fluoroquinolone with all other medications. Additionally, in-depth comparative analyses were carried out between various fluoroquinolones and a reference drug (azithromycin).

Results

A total of 1159 cases were identified, involving AEs related to pregnancy and congenital disorders. Obvious disproportionate association of abortion spontaneous and other nine AEs was identified for fluoroquinolone during gestation. Upon comparison with all the other drugs, ciprofloxacin exhibited an elevated risk of spontaneous abortion, non-site specific bone disorders congenital and 10 other significant signals. Levofloxacin demonstrated an increased risk of congenital tongue disorders and three other significant signals. Moxifloxacin displayed a noteworthy signal indicating multiple congenital cardiac abnormalities.

Conclusions

We present compelling evidence regarding pregnancy-related AEs and congenital disorders linked to fluoroquinolones. Considering perinatal and genotoxicity aspects, we explore whether levofloxacin or moxifloxacin might be preferable when fluoroquinolones are deemed necessary to balance the benefits of pregnant women and fetuses.

Pregnancy outcomes after first-trimester exposure to fluoroquinolones: Findings based on an integrated database from two Japanese institutions

Given the paucity of safety data on fluoroquinolone antibiotics in pregnancy, a prospective observational cohort study was conducted in pregnant women who sought help and advice on drug use at two teratology information institutes in Japan. The primary endpoint of the study was the incidence of major congenital anomalies. The study population included pregnant women exposed to (i) fluoroquinolones (fluoroquinolone group), (ii) β-lactams (infectious control group), or (iii) other agents considered to be nonteratogenic in humans (nonteratogenic control group) during the first trimester. The frequency of major congenital anomalies was compared across groups using a logistic regression model that adjusted for maternal age, smoking status, drinking status, facility consulted, and time of consultation. The fluoroquinolone group consisted of 411 women who had 383 children born alive. The infectious control and nonteratogenic control groups consisted of 1416 and 1482 women who had 1322 and 1401 children born alive, respectively. The incidence of major congenital anomalies was 1.5%, 2.0%, and 1.6% in the fluoroquinolone group, infectious control, and nonteratogenic control groups, respectively. Logistic regression showed that fluoroquinolone exposure is not a significant risk factor for major congenital anomalies. In conclusion, first-trimester exposure to fluoroquinolone antibiotics was not associated with increased maternal or fetal risks.

Human Listeriosis

Listeria monocytogenes is a Gram-positive facultative intracellular pathogen that can cause severe invasive infections upon ingestion with contaminated food. Clinically, listerial disease, or listeriosis, most often presents as bacteremia, meningitis or meningoencephalitis, and pregnancy-associated infections manifesting as miscarriage or neonatal sepsis. Invasive listeriosis is life-threatening and a main cause of foodborne illness leading to hospital admissions in Western countries. Sources of contamination can be identified through international surveillance systems for foodborne bacteria and strains' genetic data sharing. Large-scale whole genome studies have increased our knowledge on the diversity and evolution of L. monocytogenes, while recent pathophysiological investigations have improved our mechanistic understanding of listeriosis. In this article, we present an overview of human listeriosis with particular focus on relevant features of the causative bacterium, epidemiology, risk groups, pathogenesis, clinical manifestations, and treatment and prevention.

Australian inflammatory bowel disease consensus statements for preconception, pregnancy and breast feeding

OBJECTIVE

Because pregnancy outcomes tend to be worse in women with inflammatory bowel disease (IBD) than in those without, we aimed to update consensus statements that guide the clinical management of pregnancy in patients with IBD.

DESIGN

A multidisciplinary working group was established to formulate these consensus statements. A modified RAND/UCLA appropriateness method was used, consisting of a literature review, online voting, discussion meeting and a second round of voting. The overall agreement among the delegates and appropriateness of the statement are reported.

RESULTS

Agreement was reached for 38/39 statements which provide guidance on management of pregnancy in patients with IBD. Most medications can and should be continued throughout pregnancy, except for methotrexate, allopurinol and new small molecules, such as tofacitinib. Due to limited data, no conclusion was reached on the use of tioguanine during pregnancy. Achieving and maintaining IBD remission before conception and throughout pregnancy is crucial to optimise maternofetal outcomes. This requires a multidisciplinary approach to engage patients, allay anxieties and maximise adherence tomedication. Intestinal ultrasound can be used for disease monitoring during pregnancy, and flexible sigmoidoscopy or MRI where clinically necessary.

CONCLUSION

These consensus statements provide up-to-date, comprehensive recommendations for the management of pregnancy in patients with IBD. This will enable a high standard of care for patients with IBD across all clinical settings.

Evidence for Implementation: Management of TB in HIV and Pregnancy

PURPOSE OF REVIEW

Pregnant people living with HIV (PLWH) are at especially high risk for progression from latent tuberculosis infection (LTBI) to active tuberculosis (TB) disease. Among pregnant PLWH, concurrent TB increases the risk of complications such as preeclampsia, intrauterine fetal-growth restriction, low birth weight, preterm-delivery, perinatal transmission of HIV, and admission to the neonatal intensive care unit. The grave impact of superimposed TB disease on maternal morbidity and mortality among PLWH necessitates clear guidelines for concomitant therapy and an understanding of the pharmacokinetics (PK) and potential drug-drug interactions (DDIs) between antitubercular (anti-TB) agents and antiretroviral therapy (ART) in pregnancy.

RECENT FINDINGS

This review discusses the currently available evidence on the use of anti-TB agents in pregnant PLWH on ART. Pharmacokinetic and safety studies of anti-TB agents during pregnancy and postpartum are limited, and available data on second-line and newer anti-TB agents used in pregnancy suggest that several research gaps exist. DDIs between ART and anti-TB agents can decrease plasma concentration of ART, with the potential for perinatal transmission of HIV. Current recommendations for the treatment of LTBI, drug-susceptible TB, and multidrug-resistant TB (MDR-TB) are derived from observational studies and case reports in pregnant PLWH. While the use of isoniazid, rifamycins, and ethambutol in pregnancy and their DDIs with various ARTs are well-characterized, there is limited data on the use of pyrazinamide and several new and second-line antitubercular drugs in pregnant PLWH. Further research into treatment outcomes, PK, and safety data for anti-TB agent use during pregnancy and postpartum is urgently needed.

Ciprofloxacin exposure and adverse pregnancy outcomes: A Danish nationwide cohort study

OBJECTIVE

To examine the association between maternal exposure to ciprofloxacin and the risk of miscarriage and major malformations.

DESIGN

A nationwide register-based cohort study.

SETTING

Data were obtained from the Medical Birth Registry, the National Hospital Registry, the Danish National Prescription Registry and Statistics Denmark.

POPULATION

Data were collected in the period between 1997 and 2016 and included all registered pregnancies that ended in an elective termination, miscarriage, stillbirth or a live birth. Exposure was defined as redeeming one or more prescriptions of ciprofloxacin.

METHODS

Miscarriage was defined as a diagnosis given before 22 weeks without any medical intervention. Major malformations were classified according to EUROCAT 1.4. We matched ciprofloxacin-exposed pregnancies to unexposed pregnancies on the propensity score in a ratio 1:4. To estimate the hazard ratio (HR) of miscarriage a Cox proportional hazard regression model was used. A log binomial model was used to estimate the relative risk ratio (RR) of major malformations.

MAIN OUTCOME MEASURES

HR of miscarriage and the RR of major malformations.

RESULTS

A total of 1 650 649 pregnancies were identified. Of these, 10 250 (2050 ciprofloxacin-exposed) and 6100 (1220 ciprofloxacin-exposed) were included in the miscarriage and major malformation analysis, respectively. The HR of miscarriage was 0.99 (95% confidence interval [CI] 0.84-1.17). For major malformation, the RR was 1.01 (95% CI 0.72-1.40). For the organ-specific major malformations and the sensitivity analyses, no significant increased risks were identified.

CONCLUSION

We demonstrated no association between miscarriage and maternal ciprofloxacin exposure within the first 22 weeks of pregnancy, or between major malformations and maternal exposure during the first trimester.

TWEETABLE ABSTRACT

No association between maternal ciprofloxacin exposure and adverse pregnancy outcomes.

Association of antibiotics therapy during pregnancy with spontaneous miscarriage: a systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis of observational studies were conducted to assess the association between antibiotics use during pregnancy and spontaneous miscarriage.

METHODS

A systematic search of online databases as well as reference lists of retrieved studies were performed up to September 2018 to identify observational studies that investigated the association between antibiotics use and spontaneous miscarriage. The retrieved studies were assessed for methodological quality. Pooled relative risk (RR) and 95% confidence intervals were calculated using DerSimonian and Laird method. Random-effects meta-analysis was used to account for conceptual heterogeneity. Sensitivity analysis was performed to assess the robustness of pooled estimates using Stata software.

RESULTS

Of 1435 retrieved studies, 89 were reviewed in depth and 12 (8 prospective cohort and 4 population-based case-control studies) met the criteria for inclusion in a systematic review with 1,084,792 participants and 7015 cases of spontaneous miscarriage. Finally, 11 studies were included in the meta-analysis (one study was not included in the meta-analysis owing to methodological issues and low-quality score). Overall percentage of miscarriage in women who received antibiotics was 2.6%. After adjusting for important potential confounders, use of macrolides (RR: 1.42; 95% CI 1.04, 1.93), quinolones (RR: 2.48; 95% CI 1.46, 4.20), and tetracyclines (RR: 2.57; 95% CI 1.95, 3.38) during pregnancy were significantly associated with spontaneous miscarriage. In macrolides class, a significant positive association was found between clarithromycin and spontaneous miscarriage (RR: 1.98; 95% CI 1.46, 2.70). Sensitivity analysis demonstrated the consistency of the results, indicating that the meta-analysis model was robust.

CONCLUSION

Findings support a significant positive association between use of macrolides (especially clarithromycin), quinolones, and tetracyclines during pregnancy and spontaneous miscarriage, although it should be interpreted with caution in the context of limitations of the available data.

ERS/TSANZ Task Force Statement on the management of reproduction and pregnancy in women with airways diseases

This European Respiratory Society/Thoracic Society of Australia and New Zealand statement outlines a review of the literature and expert opinion concerning the management of reproduction and pregnancy in women with airways diseases: asthma, cystic fibrosis (CF) and non-CF bronchiectasis. Many women with these diseases are now living into reproductive age, with some developing moderate-to-severe impairment of lung function in early adulthood. The statement covers aspects of fertility, management during pregnancy, effects of drugs, issues during delivery and the post-partum period, and patients' views about family planning, pregnancy and parenthood. The statement summarises current knowledge and proposes topics for future research, but does not make specific clinical recommendations.

The role of various transporters in the placental uptake of ofloxacin in an in vitro model of human villous trophoblasts

Introduction

Six years after the US Food and Drug Administration approval of the broad-spectrum antibiotic ofloxacin (OFLX), the chiral switching of this racemic mixture resulted in a drug composed of the L-optical isomer levofloxacin (LVFX). Since both fluoroquinolones (FQs) were introduced to the pharmaceutical market, they have been widely prescribed by physicians, with careful administration during pregnancy and breastfeeding. Therefore, the role of the influx and efflux placental transporters in the concentrations of these drugs that permeate through human placental barrier model was investigated in this study.

Methods

The contribution of major carriers on the transplacental flux of OFLX and LVFX uptake into choriocarcinoma BeWo cells was evaluated in the presence vs absence of well-known inhibitors.

Results

Our results reveal that neither the influx transporters such as organic cation transporters, organic anion transporters, and monocarboxylate transporters nor the efflux transporters such as P-glycoprotein or breast cancer resistance protein significantly affected the transport of OFLX. In contrast, multiple transporters revealed pronounced involvement in the transfer of the levorotatory enantiomer in and out of the in vitro placental barrier. These data suggest a non-carrier-mediated mechanism of transport of the racemic mixture, while LVFX is subjected to major influx and efflux passage through the placental brush border membranes.

Conclusion

This study provides underlying insights to elucidate the governing factors that influence the flux of these FQs through organ barriers, in view of the controversial safety profile of these drugs in pregnant population.

Acute Kidney Injury in Pregnancy

Pregnancy-related acute kidney injury (AKI) has declined in incidence in the last three decades, although it remains an important cause of maternal and fetal morbidity and mortality. Pregnancy-related causes of AKI such as preeclampsia, acute fatty liver of pregnancy, HELLP (Hemolysis, Elevated Liver function tests, Low Platelets) syndrome, and the thrombotic microangiopathies (thrombotic thrombocytopenic purpura, atypical hemolytic-uremic syndrome [HUS]) exhibit overlapping features and often present as diagnostic dilemmas. Differentiating among these conditions may be difficult or impossible based on clinical criteria only. In difficult and rare cases, a renal biopsy may need to be considered for the exact diagnosis and to facilitate appropriate treatment, but the risks and benefits need to be carefully weighed. The use of eculizumab for the treatment of atypical HUS has demonstrated efficacy in early case reports. Non-pregnancy related causes such as volume depletion and pyelonephritis require early and aggressive resuscitative as well as antibiotic measures respectively. We will discuss in this review the various etiologies of AKI in pregnancy, current diagnostic approaches, and the latest treatment strategies. Given the recent trends of increasing maternal age at the time of pregnancy, and the availability of modern reproductive methods increase the risks of AKI in pregnancy in the coming years.

Pregnancy outcomes in women reporting exposure to ofloxacin in early pregnancy

This study aimed to analyse perinatal outcomes in ofloxacin-exposed pregnancies. This prospective study was conducted on 143 singleton pregnancies between January 2001 and April 2014, after oral ofloxacin exposure in the first trimester. A total of 33 exposed mothers were compared with 110 age-matched controls who were not exposed to teratogen. The mean maternal age was 31.4 ± 3.6 years, and the median gestational age was 4.1 weeks at the exposure. No significant differences were observed in either gestational age or in the foetal ultrasonographic long bone length between the exposed and control groups. Spontaneous abortions occurred without a significant difference (6.1% versus 10.0%, p = .733). In addition, no significant differences were found in either the stillbirths or in the major birth defects between the exposed and control groups (0% versus 2.0%, p = 1.000 and 0% versus 4.0%, p = .572, respectively). Ofloxacin has no significant effect on perinatal outcomes. Impact statement What is already known on this subject? Ofloxacin and other quinolones are avoided during pregnancy because of concerns about cartilage toxicity. But we do not find human data reporting such toxicity in a case report. What the results of this study add? Previous studies were designed for evaluation of just congenital anomaly. But in this study, we measured the fetal long bone length to replace for evaluation of fetal cartilage toxicity. In fetal stage, we can not measure the cartilage of fetus. so we measure fetal long bone length for evaluation that ofloxacin might influence to fetal cartilage growth. Even though this sample size is small. this results will be helpful to counsel pregnant women who exposed to ofloxacin during pregnancy.

Use of antibiotics during pregnancy and the risk of major congenital malformations: a population based cohort study

AIMS

Few studies have investigated the link between individual antibiotics and major congenital malformations (MCMs) including specific malformations owing to small sample size. We aimed to quantify the association between exposure to gestational antibiotic and the risk of MCMs.

METHODS

Using the Quebec pregnancy cohort (1998-2008), we included a total of 139 938 liveborn singleton alive whose mothers were covered by the "Régie de l'assurance maladie du Québec" drug plan for at least 12 months before and during pregnancy. Antibiotic exposure was assessed in the first trimester and MCMs were identified within the first year of life.

RESULTS

After adjusting for potential confounders, clindamycin exposure was associated with an increased risk of MCMs (aOR 1.34, 95% CI 1.02-1.77, 60 exposed cases), musculoskeletal system malformations (aOR 1.67, 95% CI 1.12-2.48, 29 exposed cases) and ventricular/atrial septal defect (aOR 1.81, 95% CI 1.04-3.16, 13 exposed cases). Doxycycline exposure increased the risk of circulatory system malformation, cardiac malformations and ventricular/atrial septal defect (aOR 2.38, 95% CI 1.21-4.67, 9 exposed cases; aOR 2.46, 95% CI 1.21-4.99, 8 exposed cases; aOR 3.19, 95% CI 1.57-6.48, 8 exposed cases, respectively). Additional associations were seen with quinolone (1 defect), moxifloxacin (1 defect), ofloxacin (1 defect), macrolide (1 defect), erythromycin (1 defect) and phenoxymethylpenicillin (1 defect). No link was observed with amoxicillin, cephalosporins and nitrofurantoin. Similar results were found when penicillins were used as the comparator group.

CONCLUSIONS

Clindamycin, doxycycline, quinolones, macrolides and phenoxymethylpenicillin in utero exposure were linked to organ-specific malformations. Amoxicillin, cephalosporins and nitrofurantoin were not associated with MCMs.

Use of antibiotics during pregnancy and risk of spontaneous abortion

BACKGROUND

Although antibiotics are widely used during pregnancy, evidence regarding their fetal safety remains limited. Our aim was to quantify the association between antibiotic exposure during pregnancy and risk of spontaneous abortion.

METHODS

We conducted a nested case-control study within the Quebec Pregnancy Cohort (1998-2009). We excluded planned abortions and pregnancies exposed to fetotoxic drugs. Spontaneous abortion was defined as having a diagnosis or procedure related to spontaneous abortion before the 20th week of pregnancy. The index date was defined as the calendar date of the spontaneous abortion. Ten controls per case were randomly selected and matched by gestational age and year of pregnancy. Use of antibiotics was defined by filled prescriptions between the first day of gestation and the index date and was compared with (a) non-exposure and (b) exposure to penicillins or cephalosporins. We studied type of antibiotics separately using the same comparator groups.

RESULTS

After adjustment for potential confounders, use of azithromycin (adjusted odds ratio [OR] 1.65, 95% confidence interval [CI] 1.34-2.02; 110 exposed cases), clarithromycin (adjusted OR 2.35, 95% CI 1.90-2.91; 111 exposed cases), metronidazole (adjusted OR 1.70, 95% CI 1.27-2.26; 53 exposed cases), sulfonamides (adjusted OR 2.01, 95% CI 1.36-2.97; 30 exposed cases), tetracyclines (adjusted OR 2.59, 95% CI 1.97-3.41; 67 exposed cases) and quinolones (adjusted OR 2.72, 95% CI 2.27-3.27; 160 exposed cases) was associated with an increased risk of spontaneous abortion. Similar results were found when we used penicillins or cephalosporins as the comparator group.

INTERPRETATION

After adjustment for potential confounders, use of macro-lides (excluding erythromycin), quinolones, tetracyclines, sulfonamides and metronidazole during early pregnancy was associated with an increased risk of spontaneous abortion. Our findings may be of use to policy-makers to update guidelines for the treatment of infections during pregnancy.

Safety of treatments for inflammatory bowel disease: Clinical practice guidelines of the Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD)

Inflammatory bowel diseases are chronic conditions of unknown etiology, showing a growing incidence and prevalence in several countries, including Italy. Although the etiology of Crohn's disease and ulcerative colitis is unknown, due to the current knowledge regarding their pathogenesis, effective treatment strategies have been developed. Several guidelines are available regarding the efficacy and safety of available drug treatments for inflammatory bowel diseases. Nevertheless, national guidelines provide additional information adapted to local feasibility, costs and legal issues related to the use of the same drugs. These observations prompted the Italian Group for the Study of Inflammatory Bowel Disease (IG-IBD) to establish Italian guidelines on the safety of currently available treatments for Crohn's disease and ulcerative colitis. These guidelines discuss the use of aminosalicylates, systemic and low bioavailability corticosteroids, antibiotics (metronidazole, ciprofloxacin, rifaximin), thiopurines, methotrexate, cyclosporine A, TNFα antagonists, vedolizumab, and combination therapies. These guidelines are based on current knowledge derived from evidence-based medicine coupled with clinical experience of a national working group.

Managing IBD Therapies in Pregnancy

OPINION STATEMENT

Inflammatory bowel disease is frequently diagnosed before or during key childbearing years. One of the most important factors for a healthy pregnancy is having quiescent disease prior to conception and maintaining disease remission for the duration of the pregnancy. In order to achieve that, most women will need to continue their inflammatory bowel disease (IBD) treatment during pregnancy. One of the main concerns these women have is whether these medications will have adverse effects on their growing fetus. Aminosalicylates, antibiotics, and steroids are all relatively low risk for use during pregnancy and breastfeeding. Recent studies also support the safety of continuing immunomodulators and anti-tumor necrosis factor agents during pregnancy and with breastfeeding. There seems to be an increased risk for infection, however, with use of combination therapy including both a biologic agent and an immunomodulator. Less evidence is available on the use of anti-integrins in pregnancy; however, the current data suggest they may be safe as well. Conversations about a patient's desire for pregnancy should occur between the patient and provider on a regular basis prior to conception and particularly with any change in disease activity or change in the treatment regimen. This chapter will review the current evidence on the safety of IBD medications during pregnancy and lactation so that providers can more easily discuss the importance of medication adherence for disease remission with their patients who are contemplating conception.

Treating Inflammatory Bowel Disease in Pregnancy: The Issues We Face Today

Many women of childbearing age are living with inflammatory bowel disease [IBD], yet there are limited studies on the use of IBD medications in pregnancy. In this review, we provide a comprehensive update on the safety of these medications during pregnancy, particularly thiopurines and biologicals. Antibiotics, steroids, and aminosalicylates are relatively low risk for use in pregnancy, and growing evidence supports the safety of immunomodulators and anti-tumour necrosis factor agents as well. Available studies on infliximab, adalimumab, and certolizumab pegol show no increase in adverse events during pregnancy or perinatally. Similarly, studies on lactation demonstrate that concentrations of subcutaneous anti-tumour necrosis factor biologicals are undetectable, and levels of thiopurines and infliximab are negligible in breast milk. Less is known about anti-integrins in pregnancy [eg natalizumab and vedolizumab] but currently available data suggest they may be safe as well. Although more studies are needed to examine the long-term effects of these medications on offspring, the available data provide reassuring information for providers caring for women of childbearing age.

Management of Crohn's disease in pregnancy

Crohn's disease is a chronic inflammatory bowel disease commonly diagnosed during the reproductive years. Disease management involves advocating conception during periods of stable clinical remission and continuing safe medications throughout pregnancy to achieve optimal maternal and fetal outcomes.

Urinary tract infections in pregnancy: old and new unresolved diagnostic and therapeutic problems

Urinary tract infections (UTIs) are common in pregnant women and pose a great therapeutic challenge, since the risk of serious complications in both the mother and her child is high. Pregnancy is a state associated with physiological, structural and functional urinary tract changes which promote ascending infections from the urethra. Unlike the general population, all pregnant women should be screened for bacteriuria with urine culture, and asymptomatic bacteriuria must be treated in every case that is diagnosed, as it is an important risk factor for pyelonephritis in this population. The antibiotic chosen should have a good maternal and fetal safety profile. In this paper, current principles of diagnosis and management of UTI in pregnancy are reviewed, and the main problems and controversies are identified and discussed.

Women's health issues after ileal pouch surgery

: Restorative proctocolectomy with ileal pouch-anal anastomosis (IPAA) is the surgical treatment of choice for patients with ulcerative colitis and familial polyposis who require colectomy. This surgical intervention allows for resection of colon, while offering intestinal continuity with fecal continence, discontinuation of most medications related to ulcerative colitis and reduction in the risk of colitis-associated neoplasia. As a proportion of these patients are women of childbearing age, it is important to understand the impact on reproductive health and function. Although limited data exist, restorative proctocolectomy/IPAA does not seem to adversely affect menstrual function. In general, sexual function is reported to improve postsurgery with the ability to achieve orgasm unaltered. However, dyspareunia is commonly reported post restoratively. Of concern, there are data to suggest that fertility is decreased post-IPAA. The reasons stated are pelvic adhesions and obstruction of fallopian tubes. Laparoscopic approach may improve fertility outcomes by reducing postoperative adhesions as compared with the open approach. Once achieved, pregnancy in patients with IPAA is characterized by a transient increase in stool frequency that resolves postdelivery. Whether vaginal delivery or cesarean section is preferred route of delivery in these patients is still controversial. But commonly cesarean section is advocated for patients' post-IPAA to prevent anal sphincter injury and long-term effects on pouch function. All of these issues should be included in the discussion with women who are contemplating IPAA, so they are well aware of them before deciding on the best management plan.

Pregnancy and cystic fibrosis: Approach to contemporary management

Over the previous 50 years survival of patients with cystic fibrosis has progressively increased. As a result of improvements in health care, increasing numbers of patients with cystic fibrosis are now considering starting families of their own. For the health care professionals who look after these patients, the assessment of the potential risks, and the process of guiding prospective parents through pregnancy and beyond can be both challenging and rewarding. To facilitate appropriate discussions about pregnancy, health care workers must have a detailed understanding of the various important issues that will ultimately need to be considered for any patient with cystic fibrosis considering parenthood. This review will address these issues. In particular, it will outline pregnancy outcomes for mothers with cystic fibrosis, issues that need to be taken into account when planning a pregnancy and the management of pregnancy for mothers with cystic fibrosis or mothers who have undergone organ transplantation as a result of cystic fibrosis.

Review article: the management of Crohn's disease and ulcerative colitis during pregnancy and lactation

BACKGROUND

Inflammatory bowel diseases (IBD) commonly affect young patients in the reproductive phase of their lives. The chronic and relapsing nature of IBD and the potential need for medical or surgical interventions raise concerns about family planning issues.

AIM

To review the current knowledge on IBD management in pregnant and nursing IBD patients.

METHODS

A PubMed literature search was performed using the search terms 'reproduction' and 'inflammatory bowel disease' and using the headers and main subjects of each section of this article as search terms.

RESULTS

Male and female fertility are not impaired in the majority of IBD patients. In IBD patients with quiescent disease pregnancy outcomes are not impaired in comparison to the general population, however, an increased incidence of pregnancy complications is observed in active IBD patients. As methotrexate (MTX) has been demonstrated to be teratogenic, the use of MTX is contraindicated in patients, who wish to conceive, throughout pregnancy and when nursing. However, normal pregnancies following MTX treatment at conception and later have been reported. Most of the other currently approved IBD medications are not associated with adverse pregnancy outcomes and may be used to maintain quiescent disease or to induce a rapid remission in patients with flares and active disease. Breast-feeding in IBD patients is possible and recommended.

CONCLUSIONS

The overall outcome of pregnancies in IBD patients is favourable and not different to healthy controls, thus patients with IBD should not be discouraged from having children.

Safety of antimicrobial treatment during pregnancy: a current review of resistance, immunomodulation and teratogenicity

INTRODUCTION

The extent of antibiotic use in pregnancy remains unknown but may occur in > 40% of pregnant women for various indications, at different gestational ages from different sources.

AREAS COVERED

Antibiotic resistance, alterations to the neonatal immune system causing allergy, asthma and atopic disease in later life and teratogenicity.

EXPERT OPINION

Although teratogenesis is not a major concern, it is important, and ignorance and complacency cast a long shadow. Robust evidence exists to guide clinicians in their choice of a safe agent with respect to teratogenicity. Antibiotic resistance is a major safety concern, and together with decreased research and development of new antibiotic agents, it has required legal initiatives to encourage Big Pharma to search for safe alternatives. New information from culture-independent, molecular-based techniques has resulted in a greater understanding of the adverse effects of antepartum/intrapartum antibiotics on the maternal vaginal microbiome and the neonatal gut microbiome. As this might adversely affect the development of the immature immune system and lead to asthma, allergy and atopic disease in later life, new research merits support in scrutinizing the safety of antibiotic use in pregnancy.

Therapy of complicated Crohn's disease during pregnancy--an interdisciplinary challenge

BACKGROUND

Severe courses of Crohn's disease (CD) during pregnancy are rare. However, if occurring, the risk of miscarriage and low birth weight is increased. At present, only limited data is available on the treatment of CD during pregnancy. In particular, there are no standard guidelines for surgical therapy. Nevertheless, surgery is often unavoidable if complications during the course of the disease arise.

PURPOSE

This study provides a critical overview of conventional and interventional treatment options for CD complications during pregnancy and analyses the surgical experience gained thus far. For illustrative purposes, clinical cases of three young women with a severe clinical course during pregnancy are presented.

METHODS

After treatment-refractory for conservative and interventional measures, surgery remained as the only treatment option. In all cases, a split stoma was created after resection to avoid anastomotic leaks that would endanger the lives of mother and child. The postoperative course of all three patients was uneventful, and pregnancy remained intact until delivery. No further CD specific medication was required before birth.

CONCLUSIONS

The management of CD patients during pregnancy requires close interdisciplinary co-operation between gastroenterologists, obstetricians, anaesthetists and visceral surgeons. For the protection of mother and child treatment should thus be delivered in a specialised centre. This article demonstrates the advantages of surgical therapy by focusing on alleviating CD complaints and preventing postoperative complications.

Observational cohort study of pregnancy outcome after first-trimester exposure to fluoroquinolones

Fluoroquinolones are avoided during pregnancy due to developmental toxicity in animals. The aim of this study was to assess the fetal risk after intrauterine fluoroquinolone exposure. We performed an observational study of a prospectively ascertained cohort of pregnant women exposed to a fluoroquinolone during the first trimester. Pregnancy outcomes were compared to those of a cohort exposed to neither fluoroquinolones nor teratogenic or fetotoxic drugs. The outcomes evaluated were major birth defects (structural abnormalities of medical, surgical, or cosmetic relevance), spontaneous abortion, and elective termination of pregnancy. Pregnancy outcomes of 949 women with fluoroquinolone treatment were compared with those of 3,796 nonexposed controls. Neither the rate of major birth defects (2.4%; adjusted odds ratio [OR(adj)], 0.91; 95% confidence interval [CI], 0.6 to 1.5) nor the risk of spontaneous abortion (adjusted hazard ratio [HR(adj)], 1.01; 95% CI, 0.8 to 1.3) was increased. However, there was a nonsignificant increase in major birth defects after exposure to moxifloxacin (6/93, 6.5%; crude odds ratio [OR(crude)], 2.40; 95% CI, 0.8 to 5.6). Neither a critical exposure time window within the first trimester nor a specific pattern of birth defects was demonstrated for any of the fluoroquinolones. The rate of electively terminated pregnancies was increased among the fluoroquinolone-exposed women (HR(adj), 1.32; 95% CI, 1.03 to 1.7). The gestational ages at delivery and birth weights did not differ between groups. Our study did not detect an increased risk of spontaneous abortion or major birth defects. These reassuring findings support the recommendation to allow fluoroquinolone use in early pregnancy in selected cases. After the use of moxifloxacin, a detailed fetal ultrasound examination should be considered.

Inflammatory bowel disease in women of reproductive age

Management of inflammatory bowel disease in women of reproductive age requires special attention. Even though fertility in women without previous pelvis surgery is similar to the general population, active disease at conception and during pregnancy can lead to unfavorable pregnancy and fetal outcomes. In general, most medications needed to treat inflammatory bowel disease are low risk during pregnancy and breastfeeding. Achieving and maintaining disease remission, patient education, and a multidisciplinary team approach is the key to a successful pregnancy.

Increasing use of antibiotics in pregnancy during the period 2000-2010: prevalence, timing, category, and demographics

OBJECTIVE

The aim of this study was to describe the use of antibiotics in a national population-based cohort of pregnant Danish women between 2000 and 2010.

DESIGN

Register-based, population-wide, cohort study.

SETTING

Denmark, from 2000 to 2010.

POPULATION

All pregnancies among Danish residents during the period 2000-2010 were included for analysis.

METHODS

Data were obtained from the Danish Medical Birth Registry, the Danish National Patient Registry, and the Registry of Medicinal Product Statistics. The filled prescriptions for systemic antibacterial, antimycotic, and antiviral drugs, as well as intravaginally applied antibiotics, were analysed. Associations with demographic variables were assessed using multivariate analysis.

MAIN OUTCOME MEASURES

Filled prescriptions for antibiotic drugs during pregnancy.

RESULTS

We included 987 973 pregnancies in Denmark from 2000 to 2010; 38.9% of women with a delivery and 14.8% of women with a miscarriage or termination of pregnancy had one or more antibiotic treatments during pregnancy. Systemic antibacterial drugs were the most frequently used drug group, with filled prescriptions for 33.4% of all deliveries and 12.6% of all abortions. This proportion increased from 28.4% in 2000 to 37.0% in 2010 among deliveries. The biggest change was seen for pivmecillinam, which increased among deliveries from 6.3% in 2000 to 19.5% in 2010. Obese (odds ratio 1.51; 95% CI 1.47-1.56), young (odds ratio 1.35; 95% CI 1.30-1.39), and low-educated women (odds ratio 1.37; 95% CI 1.35-1.1.39) tended to fill more prescriptions of antibiotics during pregnancy.

CONCLUSIONS

Overall, the number of women who filled prescriptions of antibiotics increased during the 11-year study period. In 2010, at least 41.5% of all deliveries were exposed to antibiotic therapy during pregnancy.

Management of patients with multidrug-resistant/extensively drug-resistant tuberculosis in Europe: a TBNET consensus statement

The emergence of multidrug-resistant (MDR) and extensively drug-resistant (XDR) tuberculosis (TB) substantially challenges TB control, especially in the European Region of the World Health Organization, where the highest prevalence of MDR/XDR cases is reported. The current management of patients with MDR/XDR-TB is extremely complex for medical, social and public health systems. The treatment with currently available anti-TB therapies to achieve relapse-free cure is long and undermined by a high frequency of adverse drug events, suboptimal treatment adherence, high costs and low treatment success rates. Availability of optimal management for patients with MDR/XDR-TB is limited even in the European Region. In the absence of a preventive vaccine, more effective diagnostic tools and novel therapeutic interventions the control of MDR/XDR-TB will be extremely difficult. Despite recent scientific advances in MDR/XDR-TB care, decisions for the management of patients with MDR/XDR-TB and their contacts often rely on expert opinions, rather than on clinical evidence.

This document summarises the current knowledge on the prevention, diagnosis and treatment of adults and children with MDR/XDR-TB and their contacts, and provides expert consensus recommendations on questions where scientific evidence is still lacking.

Gonorrhoea

INTRODUCTION

In 2012, the diagnosis rates for gonorrhoea among adults aged 20 to 24 years in the UK were 249 per 100,000 for men and 140 per 100,000 for women. Resistance to one or more antimicrobial agent is reported in more than one quarter of isolates. Co-infection with Chlamydia trachomatis is reported in 10% to 40% of people with gonorrhoea in the US and UK.

METHODS AND OUTCOMES

We conducted a systematic review and aimed to answer the following clinical questions: What are the effects of treatments for uncomplicated infections in men and non-pregnant women, and in pregnant women? What are the effects of treatments for disseminated gonococcal infection? What are the effects of dual treatment for gonorrhoea and chlamydia infection? We searched: Medline, Embase, The Cochrane Library, and other important databases up to September 2013 (Clinical Evidence reviews are updated periodically, please check our website for the most up-to-date version of this review). We included harms alerts from relevant organisations such as the US Food and Drug Administration (FDA) and the UK Medicines and Healthcare products Regulatory Agency (MHRA).

RESULTS

We found 7 studies that met our inclusion criteria. We performed a GRADE evaluation of the quality of evidence for interventions.

CONCLUSIONS

In this systematic review we present information relating to the effectiveness and safety of the following interventions: antibiotic regimens (dual treatment, multiple dose, single dose).

IBD medications during pregnancy and lactation

IBD often affects patients during their peak reproductive years. Several drugs are available for the treatment of IBD and new drugs are continuously in the pipeline. As long-term administration of medications is often necessary, the safety of drug therapy during pregnancy and breast-feeding needs to be considered in daily clinical practice. The aim of this Review is to summarize the latest information concerning the safety of medications used to treat IBD during pregnancy and lactation, as well as their effect on fertility. Although only thalidomide and methotrexate are absolutely contraindicated during pregnancy and breast-feeding, alternatives to ciprofloxacin, natalizumab and sodium phosphate should also be considered for pregnant women. Breast-feeding is also discouraged while on treatment with ciclosporin, metronidazole and ciprofloxacin. However, therapy with 5-aminosalicylic acid preparations, glucocorticoids, thiopurines and TNF inhibitors are acceptable during pregnancy and lactation. Pregnant women who have symptomatic IBD or who require therapy should have the opportunity to discuss any associated risks to their pregnancy and infant with the appropriate consultants. By ensuring that the patient and her family are informed, the clinical outcome might be optimized.

Prophylaxis and treatment of anthrax in pregnant women

OBJECTIVE

To review the safety and pharmacokinetics of antimicrobials recommended for anthrax postexposure prophylaxis and treatment in pregnant women.

DATA SOURCES

Articles were identified in the PubMed database from inception through December 2012 by searching the keywords (["pregnancy]" and [generic antibiotic drug name]). Additionally, we searched clinicaltrials.gov and conducted hand searches of references from REPROTOX, TERIS, review articles, and Briggs' Drugs in Pregnancy and Lactation.

METHODS OF STUDY SELECTION

Articles included in the review contain primary data related to the safety and pharmacokinetics among pregnant women of 14 antimicrobials recommended for anthrax postexposure prophylaxis and treatment (amoxicillin, ampicillin, chloramphenicol, clindamycin, ciprofloxacin, doripenem, doxycycline, levofloxacin, linezolid, meropenem, moxifloxacin, penicillin, rifampin, and vancomycin).

TABULATION, INTEGRATION, AND RESULTS

The PubMed search identified 3,850 articles for review. Reference hand searching yielded nine additional articles. In total, 112 articles met the inclusion criteria.

CONCLUSIONS

Overall, safety and pharmacokinetic information is limited for these antimicrobials. Although small increases in risks for certain anomalies have been observed with some antimicrobials recommended for prophylaxis and treatment of anthrax, the absolute risk of these antimicrobials appears low. Given the high morbidity and mortality associated with anthrax, antimicrobials should be dosed appropriately to ensure that antibiotic levels can be achieved and sustained. Dosing adjustments may be necessary for the β-lactam antimicrobials and the fluoroquinolones to achieve therapeutic levels in pregnant women. Data indicate that the β-lactam antimicrobials, the fluoroquinolones, and, to a lesser extent, clindamycin enter the fetal compartment, an important consideration in the treatment of anthrax, because these antimicrobials may provide additional fetal benefit in the second and third trimesters of pregnancy.

Gender analysis of moxifloxacin clinical trials

PURPOSE

To determine the inclusion of women and the sex-stratification of results in moxifloxacin Clinical Trials (CTs), and to establish whether these CTs considered issues that specifically affect women, such as pregnancy and use of hormonal therapies. Previous publications about women's inclusion in CTs have not specifically studied therapeutic drugs. Although this type of drug is taken by men and women at a similar rate, adverse effects occur more frequently in the latter.

METHODS

We reviewed 158 published moxifloxacin trials on humans, retrieved from MedLine and the Cochrane Library (1998-2010), to determine whether they complied with the gender recommendations published by U.S. Food and Drug Administration Guideline.

RESULTS

Of a total of 80,417 subjects included in the moxifloxacin CTs, only 33.7% were women in phase I, in contrast to phase II, where women accounted for 45%, phase III, where they represented 38.3% and phase IV, where 51.3% were women. About 40.9% (n=52) of trials were stratified by sex and 15.3% (n=13) and 9% (n=7) provided data by sex on efficacy and adverse effects, respectively. We found little information about the influence of issues that specifically affect women. Only 3 of the 59 journals that published the moxifloxacin CTs stated that authors should stratify their results by sex.

CONCLUSIONS

Women are under-represented in the published moxifloxacin trials, and this trend is more marked in phase I, as they comprise a higher proportion in the other phases. Data by sex on efficacy and adverse effects are scarce in moxifloxacin trials. These facts, together with the lack of data on women-specific issues, suggest that the therapeutic drug moxifloxacin is only a partially evidence-based medicine.

Update on pregnancy and breastfeeding in the era of biologics

Inflammatory bowel diseases are chronic conditions that frequently affect patients during their childbearing years. Considering the characteristics of disease and the medications used to treat it, several issues arise in the care of these patients when they attempt or achieve conception. We review the most current evidence concerning fertility and pregnancy outcomes in patients with inflammatory bowel diseases. With the exception of those women who undergo pelvic surgery, patients with inflammatory bowel diseases have no decreased fertility. Sulfasalazine decreases fertility in men. When looking at obstetrical outcomes, active disease at conception is associated with an increased risk of preterm delivery and low birth weight. While most medications used to treat inflammatory bowel diseases are low risk, some precautions need to be taken and the risk-to-benefit ratio needs to be considered on an individualized basis. In general, aminosalicylates and thiopurines should be continued, but methotrexate is contraindicated. Anti-tumour necrosis factor agents are considered safe to continue but full monoclonal antibodies do cross the placenta. As a general rule, the it is important to counsel women that conception is optimal when disease is in remission, as adverse obstetrical outcomes are directly associated with disease activity. Clinicians need to educate patients before, during and after conception, emphasizing treatment compliance.

Management of inflammatory bowel disease in pregnancy

The management of inflammatory bowel disease (IBD) in women who are pregnant or contemplating pregnancy requires special considerations. Although many of the medications in IBD treatment are generally low risk, this is not the case for all agents, and substitution of medications or adjustments in dosage or dose timing may be needed. Furthermore, while women with IBD who have not had prior pelvic surgery are as likely to conceive as non-IBD counterparts, there is evidence to suggest that pregnancy outcomes may be worse in women with IBD, particularly if they have active disease during conception or pregnancy. Therefore, a thoughtful discussion between the patient and her healthcare team is critical to ensure awareness of the possible risks of pregnancy to the mother and her infant and how these risks can be minimized with a coordinated effort in counseling, monitoring and medication adherence.

Septic arthritis due to moraxella osloensis in a rhesus macaque (Macaca mulatta)

A 5.5-y-old Chinese-origin female rhesus macaque (Macaca mulatta) presented for bilateral hindlimb lameness. The primate had been group-reared in an SPF breeding colony and was seronegative for Macacine herpesvirus 1, SIV, simian retrovirus type D, and simian T-lymphotropic virus. The macaque's previous medical history included multiple occasions of swelling in the left tarsus, and trauma to the right arm and bilateral hands. In addition, the macaque had experienced osteomyelitis of the left distal tibia and rupture of the right cranial cruciate ligament that had been surgically repaired. Abnormal physical examination findings on presentation included a thin body condition, mild dehydration, and bilaterally swollen stifles that were warm to the touch, with the right stifle more severely affected. Mild instability in the left stifle was noted, and decreased range of motion and muscle atrophy were present bilaterally. Hematologic findings included marked neutrophilia and lymphopenia and moderate anemia. Arthrocentesis and culture of joint fluid revealed Moraxella-like organisms. Treatment with enrofloxacin was initiated empirically and subsequently switched to cephalexin, which over time alleviated the joint swelling and inflammation. Definitive diagnosis of Moraxella osloensis septic arthritis was made through isolation of the organism and sequencing of the 16S rDNA region. To our knowledge, this report is the first description of Moraxella osloensis septic arthritis in a rhesus macaque.

Funding for teratology information services: up, down, and all around

Funding for Teratology Information Services has been an ongoing struggle over the 25 years of its existence. Traditional and novel funding mechanisms have been explored with varying success. The importance of providing teratology risk assessment and counseling to all women of reproductive age is now an established health care objective. Sufficient and stable funding for these services is essential.

[Guidelines for the management of Crohn's disease]

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) with uncertain etiopathogenesis. CD can involve any site of gastrointestinal tract from the mouth to anus and is associated with serious complications such as bowel strictures, perforations, and fistula formation. The incidence and prevalence rates of CD in Korea are still lower than those of Western countries, but have been rapidly increasing during the past decades. Although there are no definitive curative modalities for CD, various medical and surgical therapies are currently applied for diverse clinical situations of CD. However, a lot of decisions on the management of CD are made depending on the personal experiences and choices of physicians. To suggest preferable approaches to diverse problems of CD and to minimize the variations according to physicians, guidelines for the management of CD are needed. Therefore, IBD Study Group of the Korean Association for the Study of the Intestinal Diseases has set out to develop the guidelines for the management of CD in Korea. These guidelines were developed using the adaptation methods and encompass the treatment of inflammatory disease, stricturing disease, and penetrating disease. The guidelines also cover the indication of surgery, prevention of recurrence after surgery, and CD in pregnancy and lactation. These are the first Korean guidelines for the management of CD and the update with further scientific data and evidences is needed.

Pregnancy related issues in inflammatory bowel disease: evidence base and patients' perspective

Inflammatory bowel disease (IBD) affects women of childbearing age and can influence fertility, pregnancy and decisions regarding breastfeeding. Women with IBD need to consider the possible course of disease during pregnancy, the benefits and risks associated with medications required for disease management during pregnancy and breastfeeding and the effects of mode of delivery on their disease. When indicated, aminosalicylates and thiopurines can be safely used during pregnancy. Infliximab and Adalimumab are considered probably safe during the first two trimesters. During the third trimester the placenta can be crossed and caution should be applied. Methotrexate is associated with severe teratogenicity due to its folate antagonism and is strictly contraindicated. Women with IBD tend to deliver earlier than healthy women, but can have a vaginal delivery in most cases. Caesarean sections are generally recommended for women with active perianal disease or after ileo-anal pouch surgery.While the impact of disease activity and medication has been addressed in several studies, there are minimal studies evaluating patients' perspective on these issues. Women's attitudes may influence their decision to have children and can positively or negatively influence the chance of conceiving, and their beliefs regarding therapies may impact on the course of their disease during pregnancy and/or breastfeeding. This review article outlines the impact of IBD and its treatment on pregnancy, and examines the available data on patients' views on this subject.

When one drug affects 2 patients: a review of medication for the management of nonlabor-related pain, sedation, infection, and hypertension in the hospitalized pregnant patient

One of the most difficult challenges health care providers encounter is drug selection for pregnant patients. Drug selection can be complex as efficacy and maternal side effects must be weighed against potential risk to the embryo or fetus. Verification of an individual drug's fetal safety is limited as most evidence is deduced from epidemiologic, prospective cohort, or case-control studies. Medication selection for the pregnant inpatient is a particularly complex task as the illnesses and conditions that require hospitalization mandate different medications, and the risk versus benefit ratio can vary significantly compared to the outpatient setting. Some degree of acute pain is not uncommon among inpatients. Acetaminophen is generally considered the drug of choice in pregnancy for mild to moderate acute pain, while most opioids are thought to be safe for short-term use to manage moderate to severe pain. Providing sedation is particularly challenging as the few options available for the general population are further limited by either known increased risk of congenital malformations or very limited human pregnancy data. Propofol is the only agent recommended for continuous sedation, which has a Food and Drug Administration classification as a pregnancy category B medication. Treatment of infections in hospitalized patients requires balancing the microbiology profile against the fetal risk. Older antimicrobials proven generally safe include beta-lactams, and those with proven fetal risks include tetracyclines. However, little to no information regarding gestational use is available on the newer antimicrobials that are frequently employed to treat resistant infections more commonly found in the inpatient setting. Management of maternal blood pressure is based on the severity of blood pressure elevations and not the hypertensive classification. Agents generally considered safe to use in hypertensive pregnant patients include methyldopa, labetolol, and hydralazine, while angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, hydrochlorothiazide, and atenolol should be avoided.
