Neonatal therapy after maternal central neurotropic drug exposure-a retrospective cohort study.

OBJECTIVE: Evaluation of neonatal morbidity after maternal central neurotropic drug exposure. METHODS: Retrospective single-center level-III neonatology cohort analysis of neonates after CND from 2018 to 2021. Control group of neonates born to mothers without CND cared for at the maternity ward. RESULTS: Significantly more frequent therapy need of neonates with CND [OR 23 (95% CI: 7.8-62); RR 14 (95% CI: 5.4-37); p < 0.01]. Neonates after CND had lower Apgar-scores LM 1 [CND 8.1; CG 8.6; p < 0.05]; LM 5 [CND 9; CG 9.7; p < 0.01]; LM 10 [CND 9.6; CG 9.9; p < 0.05]. The first symptom occurred in 95.35% within 24 h (mean: 3.3 h). CND group showed significantly more often preterm delivery [OR 3.5; RR 3.2; p < 0.05], and especially cumulative multiple symptoms [OR 9.4; RR 6.6; p < 0.01] but no correlation to multiple maternal medication use (p = 0.3). CONCLUSIONS: Neonates exposed to CND are at increased risk for postnatal therapy, often due to multiple symptoms. Neonates should be continuously monitored for at least 24 h.

Epilepsy, Antiepileptic Drugs, and Adverse Pregnancy Outcomes, 1: Examination and Interpretation of Recent Research.

The age-standardized global prevalence of epilepsy is about 0.3% in women. Seizures are associated with morbidity and mortality risks; so, women with epilepsy (WWE) are usually advised antiepileptic drug (AED) treatment even during pregnancy. Women may also knowingly or unknowingly be exposed during pregnancy to AEDs advised for other on- or off-label indications. In this context, a meta-analysis of 35 adverse gestational outcomes examined in 76 observational studies found that WWE were at increased risk of most of the adverse outcomes, regardless of gestational exposure to AEDs. AEDs, especially in polytherapy, further increased at least a few of the gestational risks, including risks of congenital conditions, neonatal intensive care unit admission, small for gestational age, low birth weight, and neonatal/infant death (it is unclear whether the lack of statistical significance for the remaining risks was because AED exposure was truly limited to these risks or whether the nonsignificant analyses were underpowered). Reassuringly, the increases in risk were mostly in the small to modest range. This meta-analysis pooled unadjusted risks (which would probably be larger than adjusted risks), so readers are informed about expected findings in the population but not about cause-effect relationships that may be cautiously hypothesized from adjusted analyses. A take-home message is that, because of the wide range of outcomes for which risk is increased, WWE should be closely monitored and followed all through pregnancy, regardless of treatment with AEDs. This article also provides readers with suggestions on how to critically interpret literature with regard to 8 matters: confounding by indication and confounding by severity of indication, as specific to the indication for AED prescription; unadjusted and adjusted analyses; the base rate of an outcome in the population; the examination of multiple outcomes; the uniform direction of findings; the sample numbers; the timing of AED exposure; and self-fulfilling prophecies.

Correlation of drug dose estimated from national prescription registers with mean blood level of antiseizure medication in pregnancy.

PURPOSE: The purpose was to examine the correlation of antiseizure medication drug dose estimated from prescription fill records from prescription registers with blood levels during pregnancy. METHODS: We conducted a Nation-wide study of mothers who gave birth in Denmark between 1 January 2014 and 31 December 2018 using data from Danish Prescription and Laboratory Registers. We identified mothers with blood level measurements of antiseizure medication. The main exposure was estimated antiseizure medication dosage estimated from pregnancy-filled prescriptions in the Danish Prescription Register. The main outcome was the correlation of estimated dose with mean blood level of antiseizure medication in pregnancy. For privacy reasons, the number of blood level measurement and prescription fills were rounded to nearest 10, but proportions reported as exact values. RESULTS: Among 298 560 pregnancies, we identified pregnancies with recorded prescription fill from the prescription register for valproate (N = 90), lamotrigine (N = 1360), levetiracetam (N = 340), topiramate (N = 100), and carbamazepine (N = 60). In these pregnancies, blood level measurements were available in 50 (53%) pregnancies for valproate, 850 (62%) pregnancies for lamotrigine, 320 (93%) pregnancies for levetiracetam, 50 (68%) pregnancies for carbamazepine, and 40 (35%) pregnancies for topiramate. Pearsons's correlation coefficients for the correlation of estimated antiseizure medication dose with mean blood levels were 0.67 (p < 0.0001) for valproate, 0.63 (p < 0.0001) for lamotrigine, 0.63 (p < 0.0001) for levetiracetam, 0.76 (<0.0001) for carbamazepine and 0.89 (<0.0001) for topiramate. CONCLUSIONS: Dose of antiseizure medication estimated from prescription fills was a good proxy for blood levels and thus for biological exposure in pregnancy, suggesting that administrative prescription fill records may be a valuable resource for estimating exposure to antiseizure medication in pregnancy.

Pharmacotherapy of Chronic Neuropsychiatric Conditions During Pregnancy.

Many pregnant persons will experience neuropsychiatric conditions during pregnancy, including migraine, attention deficit disorder, depression, and anxiety. Treatment of each of these conditions requires shared decision-making among the individual, family, and health care team. Although medications may include risk, the benefits often outweigh the potential fetal risks. In this article, we review pharmacologic treatment options for each of these conditions and appropriate use in pregnancy to maintain the stability of conditions and to optimize maternal and fetal outcomes.

Therapeutic Drug Monitoring of Levetiracetam in Different Trimesters of Pregnant Women with Epilepsy in a Tertiary Care Center: A Prospective Study.

BACKGROUND: Levetiracetam is the most commonly used antiepileptic drug in pregnant women due to its low teratogenic risk profile, favorable pharmacokinetic characteristics, and safety profile. Serum levels of levetiracetam vary in epilepsy during pregnancy. Therefore, the aim of the study was to evaluate the serum levels of levetiracetam during different trimesters of pregnancy by using therapeutic drug monitoring (TDM). MATERIALS AND METHODS: This was a single-center, prospective study. Pregnant women with epilepsy on levetiracetam were enrolled after getting written informed consent from them. Serum trough levels of levetiracetam were estimated at all trimesters by high-performance liquid chromatography (HPLC). RESULTS: The study included 16 participants with mean ± standard deviation (SD) age of 27.75 ± 4 years. There were nine (56.2%) participants with generalized seizure disorder and seven (43.8%) participants of focal seizure disorder. Among 16 patients, 10 (62.5%) participants were on levetiracetam alone and six (37.5%) participants were on levetiracetam combined with other antiepileptic drugs. In a total of 48 trough samples, 45 sample concentrations were below the therapeutic range of 12-46 mg/l and three sample concentrations were within the therapeutic range. There was a statistically significant difference in the concentration-dose ratio (CDR) of levetiracetam between the third and first trimesters (P-value 0.018). CONCLUSION: There was a statistically significant difference in serum levetiracetam concentration between the third and first trimesters. A well-conducted, intensive pharmacokinetic sampling study in PWWE with a control group is needed in future to evaluate the whole pharmacokinetic profile of levetiracetam and to correlate the clinical outcome.

Italian S3-Guideline on the treatment of Atopic Eczema - Part 2: non-systemic treatments and treatment recommendations for special AE patient populations, adapted from EuroGuiDerm by the Italian Society of Dermatology and STD (SIDEMAST), the Italian Association of Hospital Dermatologists (ADOI) and the Italian Society of Allergological and Occupational Dermatology (SIDAPA).

SIDeMaST (Società Italiana di Dermatologia Medica, Chirurgica, Estetica e delle Malattie Sessualmente Trasmesse) contributed to the development of the present guideline on the systemic treatment of chronic plaque psoriasis. With the permission of EuroGuiDerm, SIDeMaST adapted the guideline to the Italian healthcare context to supply a reliable and affordable tool to Italian physicians who take care of patients affected by atopic dermatitis. The evidence- and consensus-based guideline on atopic eczema was developed in accordance with the EuroGuiDerm Guideline and Consensus Statement Development Manual. Four consensus conferences were held between December 2020 and July 2021. Twenty-nine experts (including clinicians and patient representatives) from 12 European countries participated. This second part of the guideline includes recommendations and detailed information on basic therapy with emollients and moisturizers, topical anti-inflammatory treatment, antimicrobial and antipruritic treatment and UV phototherapy. Furthermore, this part of the guideline covers techniques for avoiding provocation factors, as well as dietary interventions, immunotherapy, complementary medicine and educational interventions for patients with atopic eczema and deals with occupational and psychodermatological aspects of the disease. It also contains guidance on treatment for pediatric and adolescent patients and pregnant or breastfeeding women, as well as considerations for patients who want to have a child. A chapter on the patient perspective is also provided. The first part of the guideline, published separately, contains recommendations and guidance on systemic treatment with conventional immunosuppressive drugs, biologics and janus kinase (JAK) inhibitors, as well as information on the scope and purpose of the guideline, and a section on guideline methodology.

Teratogenesis, Perinatal, and Neurodevelopmental Outcomes After In Utero Exposure to Antiseizure Medication: Practice Guideline From the AAN, AES, and SMFM.

This practice guideline provides updated evidence-based conclusions and recommendations regarding the effects of antiseizure medications (ASMs) and folic acid supplementation on the prevalence of major congenital malformations (MCMs), adverse perinatal outcomes, and neurodevelopmental outcomes in children born to people with epilepsy of childbearing potential (PWECP). A multidisciplinary panel conducted a systematic review and developed practice recommendations following the process outlined in the 2017 edition of the American Academy of Neurology Clinical Practice Guideline Process Manual. The systematic review includes studies through August 2022. Recommendations are supported by structured rationales that integrate evidence from the systematic review, related evidence, principles of care, and inferences from evidence. The following are some of the major recommendations. When treating PWECP, clinicians should recommend ASMs and doses that optimize both seizure control and fetal outcomes should pregnancy occur, at the earliest possible opportunity preconceptionally. Clinicians must minimize the occurrence of convulsive seizures in PWECP during pregnancy to minimize potential risks to the birth parent and to the fetus. Once a PWECP is already pregnant, clinicians should exercise caution in attempting to remove or replace an ASM that is effective in controlling generalized tonic-clonic or focal-to-bilateral tonic-clonic seizures. Clinicians must consider using lamotrigine, levetiracetam, or oxcarbazepine in PWECP when appropriate based on the patient's epilepsy syndrome, likelihood of achieving seizure control, and comorbidities, to minimize the risk of MCMs. Clinicians must avoid the use of valproic acid in PWECP to minimize the risk of MCMs or neural tube defects (NTDs), if clinically feasible. Clinicians should avoid the use of valproic acid or topiramate in PWECP to minimize the risk of offspring being born small for gestational age, if clinically feasible. To reduce the risk of poor neurodevelopmental outcomes, including autism spectrum disorder and lower IQ, in children born to PWECP, clinicians must avoid the use of valproic acid in PWECP, if clinically feasible. Clinicians should prescribe at least 0.4 mg of folic acid supplementation daily preconceptionally and during pregnancy to any PWECP treated with an ASM to decrease the risk of NTDs and possibly improve neurodevelopmental outcomes in the offspring.

Use of biologics in Chinese pregnant patients with deficiency of interleukin-36 receptor antagonist (DITRA): A case series.

OBJECTIVE: Impetigo herpetiformis (IH) is a rare form of pustular psoriasis which may result in maternal and fetal morbidity and even mortality. Deficiency of interleukin-36 receptor antagonist (DITRA) is the most frequently identified genetic defect of IH. Currently there are no biologics approved for IH despite the revolutionary role of biologics in the treatment of plaque and pustular psoriasis. Anecdotal reports of biologics use in DITRA patients with IH are also limited. CASE REPORTS: We present herein a case series of 6 Chinese IH patients harboring IL36RN gene c.115+6T>C mutation during 8 pregnancies, treated with various biologics, including adalimumab, etanercept and secukinumab. CONCLUSION: Most pregnancy courses were uneventful, except for one woman who had recurrent episodes of decreased fetal heart rate variability after adalimumab injections, which subsided after switching to etanercept. The treatment effectiveness and safety demonstrated in our cases suggested the role of biologics for the treatment of IH in patients with DITRA.

Efficacy of a single low dose of esketamine after childbirth for mothers with symptoms of prenatal depression: randomised clinical trial.

OBJECTIVE: To determine whether a single low dose of esketamine administered after childbirth reduces postpartum depression in mothers with prenatal depression. DESIGN: Randomised, double blind, placebo controlled trial with two parallel arms. SETTING: Five tertiary care hospitals in China, 19 June 2020 to 3 August 2022. PARTICIPANTS: 364 mothers aged ≥18 years who had at least mild prenatal depression as indicated by Edinburgh postnatal depression scale scores of ≥10 (range 0-30, with higher scores indicating worse depression) and who were admitted to hospital for delivery. INTERVENTIONS: Participants were randomly assigned 1:1 to receive either 0.2 mg/kg esketamine or placebo infused intravenously over 40 minutes after childbirth once the umbilical cord had been clamped. MAIN OUTCOME MEASURES: The primary outcome was prevalence of a major depressive episode at 42 days post partum, diagnosed using the mini-international neuropsychiatric interview. Secondary outcomes included the Edinburgh postnatal depression scale score at seven and 42 days post partum and the 17 item Hamilton depression rating scale score at 42 days post partum (range 0-52, with higher scores indicating worse depression). Adverse events were monitored until 24 hours after childbirth. RESULTS: A total of 364 mothers (mean age 31.8 (standard deviation 4.1) years) were enrolled and randomised. At 42 days post partum, a major depressive episode was observed in 6.7% (12/180) of participants in the esketamine group compared with 25.4% (46/181) in the placebo group (relative risk 0.26, 95% confidence interval (CI) 0.14 to 0.48; P<0.001). Edinburgh postnatal depression scale scores were lower in the esketamine group at seven days (median difference -3, 95% CI -4 to -2; P<0.001) and 42 days (-3, -4 to -2; P<0.001). Hamilton depression rating scale scores at 42 days post partum were also lower in the esketamine group (-4, -6 to -3; P<0.001). The overall incidence of neuropsychiatric adverse events was higher in the esketamine group (45.1% (82/182) v 22.0% (40/182); P<0.001); however, symptoms lasted less than a day and none required drug treatment. CONCLUSIONS: For mothers with prenatal depression, a single low dose of esketamine after childbirth decreases major depressive episodes at 42 days post partum by about three quarters. Neuropsychiatric symptoms were more frequent but transient and did not require drug intervention. TRIAL REGISTRATION: ClinicalTrials.gov NCT04414943.

The impact of pregnancy on the pharmacokinetics of antiseizure medications: A systematic review and meta-analysis of data from 674 pregnancies.

OBJECTIVE: Increasing evidence suggests that the physiological changes of pregnancy may impact pharmacokinetics of antiseizure medications (ASM), and this may affect treatment outcomes. The aim of this study was to quantify the pregnancy impact on the ASM pharmacokinetics. METHODS: A systematic literature search was conducted in PubMed/EMBASE in November 2022 and updated in August 2023 for studies comparing levels of ASM in the same individuals during pregnancy and in the preconception/postpartum period. Alteration ratios between the 3rd trimester and baseline were estimated. We also performed a random-effects meta-analysis calculating between-timepoint differences in mean differences (MDs) and 95% confidence intervals (95%CIs) for dose-adjusted plasma concentrations (C/D ratios). Study quality was assessed using the ClinPK guidelines. RESULTS: A total of 65 studies investigating 15 ASMs in 674 pregnancies were included. The largest differences were reported for lamotrigine, oxcarbazepine and levetiracetam (alteration ratio 0.42, range 0.07-2.45, 0.42, range 0.08-0.82 and 0.52, range 0.04-2.77 respectively): accordingly, C/D levels were lower in the 3rd trimester for lamotrigine, levetiracetam and the main oxcarbazepine metabolite monohydroxycarbazepine (MD = -12.33 × 10-3, 95%CI = -16.08 to -8.58 × 10-3 (µg/mL)/(mg/day), p < 0.001, MD = -7.16 (µg/mL)/(mg/day), 95%CI = -9.96 to -4.36, p < 0.001, and MD = -4.87 (µg/mL)/(mg/day), 95%CI = -9.39 to -0.35, p = 0.035, respectively), but not for oxcarbazepine (MD = 1.16 × 10-3 (µg/mL)/(mg/day), 95%CI = -2.55 to 0.24 × 10-3, p = 0.10). The quality of studies was acceptable with an average rating score of 11.5. CONCLUSIONS: Data for lamotrigine, oxcarbazepine (and monohydroxycarbazepine) and levetiracetam demonstrate major changes in pharmacokinetics during pregnancy, suggesting the importance of therapeutic drug monitoring to assist clinicians in optimizing treatment outcomes.

Pharmacokinetics of Monoclonal Antibodies Throughout Pregnancy: A Systematic Literature Review.

BACKGROUND AND OBJECTIVE: Although little information is available on the pharmacokinetics (PK) of monoclonal antibodies (mAbs) during pregnancy, multiple mAbs are being used during pregnancy for various indications. The aim of this systematic literature review was to characterize the PK of mAbs throughout pregnancy. METHODS: A systematic literature search was carried out in PubMed and Embase on 21 April 2023. Articles were included when information on PK or exposure parameters of mAbs in pregnant women was available. RESULTS: A total of 42 relevant articles were included, of which eight discussed adalimumab, three certolizumab pegol, five eculizumab, one golimumab, 12 infliximab (IFX), two natalizumab, one canakinumab, one omalizumab, five tocilizumab, eight ustekinumab, and five vedolizumab. One of the 42 studies reported information on clearance (CL) and volume of distribution (VD) of IFX; all other studies only reported on serum concentrations in the pre-pregnancy state, different trimesters, and the postpartum period. For all of the assessed mAbs except IFX, serum concentrations were similar to concentrations in the pre-pregnancy state or modestly decreased. In contrast, IFX trough concentrations generally increased in the second and third trimesters in comparison to the non-pregnant state. CONCLUSION: Available information suggests that the anatomical and physiological changes throughout pregnancy may have meaningful effects on the PK of mAbs. For most mAbs (not IFX), modestly higher dosing (per mg) maybe needed during pregnancy to sustain a similar serum exposure compared to pre-pregnancy.

Anti-GBM disease in pregnancy.

We present the case of a pregnant woman in her 20s who presented in her second trimester with severe pulmonary haemorrhage and dialysis-dependent acute kidney failure due to antiglomerular basement membrane (GBM) disease. Responding to therapy, she recovered kidney function and delivered a baby. During her pregnancy, she developed cytomegalovirus viraemia, gestational diabetes and pre-eclampsia. Here, we report the first combined use of cyclophosphamide, rituximab and intensified plasma exchange in anti-GBM disease in pregnancy, allowing minimal exposure to cytotoxic medication, resulting in live birth and dialysis independence.

Switching from paliperidone palmitate 3-monthly long-acting injection to oral aripiprazole in a pregnant woman with schizophrenia: a case report and short review.

Treatment with long-acting injection (LAI) antipsychotics, such as paliperidone palmitate, has improved the quality of life in terms of symptoms and prevention of relapses in patients with schizophrenia. Although there are plenty of evidences about the efficacy and safety of paliperidone palmitate 3-monthly injection (PP3M) in adults with schizophrenia, literature appears lacking about the use of LAIs during pregnancy. We hereby describe the clinical case of a pregnant woman affected by schizophrenia (DSM-5-TR), taking pharmacological treatment of PP3M. Considering the inadequate evidence regarding the use of PP3M in pregnancy in agreement with the patient, we switched PP3M to an oral therapy with aripiprazole. The switch to oral aripiprazole allowed the patient to improve her sense of autonomy and strengthen the therapeutic relationship. To our knowledge, this is the first case report monitoring an entire pregnancy of a women affected by schizophrenia in treatment with PP3M injection and oral aripiprazole. No obstetrical or fetal complications were reported. As the research in this field is very demanding, it would be precipitous to derive final conclusions from the current case report, but we hope to build a growing number of data that would allow us to make more appropriate and safe therapeutic choices in such a vulnerable phase as the peripartum.

Anti-tumor necrosis factor-α therapy may not be safe during pregnancy in women with inflammatory bowel disease: an updated meta-analysis and systematic review.

BACKGROUND: Inflammatory Bowel Disease (IBD) affects reproductive-aged women. Active disease can lead to decreased fertility. Although the vast majority of international guidelines recommend for the continuation of anti-TNF-α during pregnancy, recent studies have raised concerns about the safety of anti-tumor necrosis factor-α (TNF-α) therapy during pregnancy, both for patients and for physicians. METHODS: Studies that evaluate the safety of anti-TNF-α therapy in pregnant women with IBD were identified using bibliographical searches. An updated meta-analysis was performed for pregnancy outcomes, such as live birth, abortion, still birth, preterm birth, low birth weight, congenital abnormalities, and neonatal infection. Odds ratio (OR) with 95% confidence interval (CI) are reported. Data on disease activity, timing of anti-TNF-α therapy were collected for further analysis. RESULTS: Overall, 11 studies were screened from on-line databases and international meeting abstracts. An increased risk of abortion (OR, 1.33; 95% CI, 1.02-1.74; P = 0.04) and preterm birth (OR, 1.16; 95% CI, 1.05-1.28; P = 0.004), and a decreased risk of live birth (OR, 0.83; 95% CI, 0.74-0.94; P = 0.002]) were found in the anti-TNF-α therapy group compared with the control group (no use of anti-TNF-α therapy). The subgroup analyses based on the disease activity showed there is no significant association between the use of anti-TNF-α therapy during pregnancy on adverse pregnancy outcomes of abortion, preterm birth, and live birth. The rates of still birth, low birth weight, and congenital abnormalities in the anti-TNF-α therapy group were not significantly different from those in the control group. CONCLUSIONS: Anti-TNF-α therapy does not increase the risks of still birth, low birth weight, and congenital abnormalities; however it may be assicated with increased risks of abortion and preterm birth, which are accompanied by a lower rate of live birth. Although these findings may be confounding by potential disease activity, they offer some opposite viewpoints with biologic agent use. Therefore, more studies are required to further confirm the safety of anti-TNF-α therapy in pregnancy with IBD.

The timing, duration, and severity of nausea and vomiting of pregnancy and adverse birth outcomes among controls without birth defects in the National Birth Defects Prevention Study.

BACKGROUND: Nausea and vomiting of pregnancy (NVP) occurs in approximately 70% of pregnant people, with varying severity and duration. Treatments include pharmacologic and herbal/natural medications. The associations between NVP and birth outcomes, including preterm birth, small for gestational age (SGA), and low birth weight are inconclusive. OBJECTIVE: To determine whether NVP and reported medications are associated with adverse birth outcomes. METHODS: We used data from the population-based, multisite National Birth Defects Prevention Study (1997-2011) to evaluate whether self-reported NVP according to timing, duration, and severity or its specific treatments were associated with preterm birth, SGA, and low birth weight among controls without birth defects. Odds ratios (aOR) and 95% confidence intervals (CI) were adjusted for sociodemographic, reproductive, and medical factors. For any NVP, duration, treatment use, and severity score analyses, the comparison group was participants with no reported NVP. For timing analyses, the comparison group was women with no reported NVP in the same trimester of pregnancy. RESULTS: Among 6018 participants, 4339 (72.1%) reported any NVP. Among those with NVP, moderate or severe symptoms were more common than mild symptoms. Any versus no NVP was not associated with any of the outcomes of interest. NVP in months 4-6 (aOR 1.21, 95% CI: 1.00, 1.47) and 7-9 (aOR 1.57, 95% CI: 1.22, 2.01) of pregnancy were associated with an increase in the risk of preterm birth. NVP lasting one trimester in duration was associated with decrease in risk of SGA (aOR: 0.74, 95% CI: 0.58, 0.95), and NVP present in every trimester of pregnancy had a 50% increase in risk of preterm birth (aOR: 1.50, 95% CI: 1.11, 2.05). For NVP in months 7-9 and preterm birth, ORs were elevated for moderate (aOR: 1.82, 95% CI: 1.26, 2.63), and severe (aOR: 1.53, 95% CI: 1.06, 2.19) symptoms. NVP was not significantly associated with low birth weight. Our analyses of medications were limited by small numbers, but none suggested increased risk of adverse outcomes associated with use of the medication. CONCLUSION: Mild NVP and NVP limited to early pregnancy appear to have no effect or a small protective effect on birth outcomes. Long-lasting NVP, severe NVP, and NVP later in pregnancy may increase risk of preterm birth and SGA.

Tofacitinib as a Rescue Therapy for Ulcerative Colitis in Pregnancy.

Tofacitinib, a potentially teratogenic nonselective Janus Kinase inhibitor was used as salvage therapy for ulcerative colitis during pregnancy with corticosteroids, maintenance ustekinumab, and rectal 5-ASA therapy. Corticosteroid-free remission ensued, resulting in term delivery without congenital malformations and avoidance of colectomy.

Extended-release versus oral buprenorphine as opioid maintenance treatment during pregnancy-maternal and neonatal outcomes.

OBJECTIVE: To get information on subcutaneous extended-release buprenorphine as opioid maintenance treatment during pregnancy, we compared it to orally administered buprenorphine and buprenorphine-naloxone treatments. We hypothesized that maternal and neonatal outcomes do not differ between the treatment groups. Study design In this population-based cohort study, 60 pregnant individuals receiving non-changed opioid maintenance treatment for opioid use disorder with a buprenorphine product from the time before conception to the time after delivery and their newborns were included. They were divided into three groups based on the pharmacotherapy with subcutaneous extended-release buprenorphine, sublingual buprenorphine, or buprenorphine-naloxone. Statistical analyses were conducted using Fischer's exact tests, ANOVA tests, and Kruskal-Wallis tests. All the statistical tests were two-tailed. RESULTS: The frequency of pregnancy or delivery complications did not significantly differ between the group receiving extended-release buprenorphine and the other groups. During pregnancy, 38 % of the women used illicit drugs concomitantly, with equal frequency in the extended-release buprenorphine group and the other groups. Of the neonates, 93 % were born full-term and 90 % got at least eight Apgar points in one minute age, without significant differences between the groups (p = 0.57). The need for pharmacotherapy for neonatal opioid withdrawal syndrome was the lowest in the extended-release buprenorphine group (25 %) and highest in the sublingual buprenorphine group (67 %). Still, the difference between the treatment groups did not reach statistical significance (p = 0.17). Among all neonates, the breastfed infants were less likely to receive pharmacotherapy for withdrawal symptoms than the formula-fed ones (p = 0.048). CONCLUSIONS: Extended-release buprenorphine with steady drug concentration seems to be a promising pharmacotherapy option during pregnancy for mothers. Maternal health during pregnancy may contribute to the well-being of newborns. Larger trials are urgently needed to confirm these results..

Drug-Induced Liver Injury in Pregnancy: The U.S. Drug-Induced Liver Injury Network Experience.

There are limited data on the causative agents and characteristics of drug-induced liver injury in pregnant individuals. Data from patients with drug-induced liver injury enrolled in the ongoing multicenter Drug-Induced Liver Injury Network between 2004 and 2022 and occurring during pregnancy or 6 months postpartum were reviewed and compared with cases of drug-induced liver injury in nonpregnant women of childbearing age. Among 325 individuals of childbearing age in the Drug-Induced Liver Injury Network, 16 cases of drug-induced liver injury (5%) occurred during pregnancy or postpartum. Compared with drug-induced liver injury in nonpregnant women, pregnancy-related drug-induced liver injury was more severe ( P <.05). One elective termination and three miscarriages were documented; there were no maternal deaths. We recommend that isoniazid for latent tuberculosis be deferred to the postpartum period whenever feasible and that ß-blockers or calcium channel blockers rather than methyldopa be used for hypertension management during pregnancy.
