Overuse of antibiotics for urinary tract infections in pregnant refugees, Lebanon.

Objective: To determine whether adding urine culture to urinary tract infection diagnosis in pregnant women from refugee camps in Lebanon reduced unnecessary antibiotic use. Methods: We conducted a prospective, cross-sectional study between April and June 2022 involving pregnant women attending a Médecins Sans Frontières sexual reproductive health clinic in south Beirut. Women with two positive urine dipstick tests (i.e. a suspected urinary tract infection) provided urine samples for culture. Bacterial identification and antimicrobial sensitivity testing were conducted following European Committee on Antimicrobial Susceptibility Testing guidelines. We compared the characteristics of women with positive and negative urine culture findings and we calculated the proportion of antibiotics overprescribed or inappropriately used. We also estimated the cost of adding urine culture to the diagnostic algorithm. Findings: The study included 449 pregnant women with suspected urinary tract infections: 18.0% (81/449) had positive urine culture findings. If antibiotics were administered following urine dipstick results alone, 368 women would have received antibiotics unnecessarily: an overprescription rate of 82% (368/449). If administration was based on urine culture findings plus urinary tract infection symptoms, 144 of 368 women with negative urine culture findings would have received antibiotics unnecessarily: an overprescription rate of 39.1% (144/368). The additional cost of urine culture was 0.48 euros per woman. Conclusion: A high proportion of pregnant women with suspected urinary tract infections from refugee camps unnecessarily received antibiotics. Including urine culture in diagnosis, which is affordable in Lebanon, would greatly reduce antibiotic overprescription. Similar approaches could be adopted in other regions where microbiology laboratories are accessible.

The integration of ortho-plastic limb salvage teams in the humanitarian response to violence-related open tibial fractures: evaluating outcomes in the Gaza Strip.

BACKGROUND: Limb salvage by ortho-plastic teams is the standard protocol for treating open tibial fractures in high-income countries, but there's limited research on this in conflict settings like the Gaza Strip. This study assessed the clinical impact of gunshot-related open tibial fractures, compared patient management by orthopedic and ortho-plastic teams, and identified the risk factors for bone non-union in this context. METHODS: A retrospective review of medical records was conducted on Gaza Strip patients with gunshot-induced-open tibial fractures from March 2018 to October 2020. Data included patient demographics, treatments, and outcomes, with at least one year of follow-up. Primary outcomes were union, non-union, infection, and amputation. RESULTS: The study included 244 injured individuals, predominantly young adult males (99.2%) with nearly half (48.9%) having Gustilo-Anderson type IIIB fractures and more than half (66.8%) with over 1 cm of bone loss. Most patients required surgery, including rotational flaps and bone grafts with a median of 3 admissions and 9 surgeries. Ortho-plastic teams managed more severe muscle and skin injuries, cases with bone loss > 1 cm, and performed less debridement compared to other groups, though these differences were not statistically significant. Non-union occurred in 53% of the cases, with the ortho-plastic team having the highest rate at 63.6%. Infection rates were high (92.5%), but no significant differences in bone or infection outcomes were observed among the different groups. Logistic regression analysis identified bone loss > 1 cm, vascular injury, and the use of a definitive fixator at the first application as predictors of non-union. CONCLUSIONS: This study highlights the severity and complexity of such injuries, emphasizing their significant impact on patients and the healthcare system. Ortho-plastic teams appeared to play a crucial role in managing severe cases. However, further research is still needed to enhance our understanding of how to effectively manage these injuries.

Management of rifampicin-resistant tuberculosis in conflict-affected areas: The case of Iraq.

Since December 2019, the World Health Organization (WHO) has encouraged National Tuberculosis Programs to deprioritize the use of injectable-containing regimens and roll-out all-oral bedaquiline-containing regimens for rifampicin-resistant tuberculosis (RR-TB) treatment. Consequently, Iraq gradually replaced the injectable-containing regimen with an all-oral regimen, including bedaquiline. To assess treatment enrolment and outcomes of both regimens during a transitioning phase in Iraq, where health system services are recovering from decades of war, we conducted a nationwide retrospective cohort study using routinely collected programmatic data for patients enrolled between 2019-2021. We describe treatment enrolment and use logistic regression to identify predictors of unfavorable treatment outcomes (failure, death, or lost to follow-up), including regimen type. Nationwide, a total of 301 RR-TB patients started treatment, of whom 167 concluded treatment. The proportion of patients enrolled on the all-oral regimen increased from 53.2% (50/94) in 2020, to 75.5% (80/106) in 2021. Successful treatment was achieved in 82.1% (32/39) and 63.3% (81/128), for all-oral and injectable-containing regimens respectively. Moreover, the proportion of lost to follow-up was lower among those treated with the all-oral versus the long injectable-containing regimen; respectively 2.6% (1/39) versus 17.9% (23/128: p = 0.02). Unfavorable treatment outcome was associated with male gender (aOR 2.12, 95%CI:1.02-4.43) and age <15 years (vs 30-49 years, aOR 5.80, 95%CI:1.30-25.86). Regimen type (aOR 2.37, 95%CI: 0.91-6.13) was not significantly associated with having an unfavorable treatment outcome. In Iraq, the use of bedaquiline-containing all-oral regimen resulted in a high treatment success and reduced lost to follow-up.

The challenge of antibiotic resistance in post-war Mosul, Iraq: an analysis of 20 months of microbiological samples from a tertiary orthopaedic care centre.

OBJECTIVES: Iraq has suffered unrest and conflicts in the past decades, leaving behind a weakened healthcare system. In 2018, Médecins Sans Frontières (MSF) opened a tertiary orthopaedic care centre in Mosul providing reconstructive surgery with access to microbiological analysis. METHODS: A retrospective cross-sectional analysis of microbiological and clinical data of patients admitted between April 2018 and December 2019. RESULTS: There were 174 patients who were included in this study; there were more males than females (135 to 38, respectively), and the mean age was 32.6 y. Of the 174 patients, the majority had more than one bacterial isolate detected (n = 122, 70.1%); 141 (81.0%) had at least one multidrug-resistant (MDR) isolate detected during their hospital stay. Staphylococcus aureus (n = 197, 48.2%) was the most common organism isolated. Overall, most isolates detected were MDR (n = 352, 86%), mostly methicillin-resistant S. aureus (n = 186, 52.8%) or extended-spectrum beta-lactamase-producing Enterobacterales (n = 117, 33.2%). Among patients admitted to the operating department (n = 111, 63.7%), 81.1% (n = 90) were admitted for violent trauma injuries. Patients who had more than one procedure performed per surgery had significantly increased odds of having at least one MDR organism isolated (OR 8.66, CI 1.10-68.20, P = 0.03). CONCLUSION: This study describes a high prevalence of antibiotic resistance in patients with trauma-related wounds in Mosul, Iraq. It highlights the importance of microbiological analysis and ongoing surveillance to provide optimal treatment. Additionally, it underscores the importance of infection prevention and control measures as well as antibiotic stewardship.

How COVID-19 highlighted the need for infection prevention and control measures to become central to the global conversation: experience from the conflict settings of the Middle East.

Within just a few months, the coronavirus disease 2019 (COVID-19) pandemic managed to bring to the foreground the conversation that infection prevention and control (IPC) experts have been pushing for decades regarding the control of the spread of infections. Implementing the basics of IPC has been a challenge for all affected countries battling with an exponential COVID-19 curve of infection. Preventing nosocomial transmission of the disease has been difficult in highly resourced and stable contexts, but even more so in the conflict context of the Middle East. COVID-19 has added further challenges to the long list of existing ones, hindering the implementation of the optimal IPC measures that are necessary to break the chain of infection of both respiratory and non-respiratory infections in those settings. This paper outlines and gives examples of the challenges faced across the Middle East conflict setting and serves as a call for action for IPC to be prioritized, given the resources needed, and fed with contextualized evidence.

Self-reported medication adherence among patients with diabetes or hypertension, Médecins Sans Frontières Shatila refugee camp, Beirut, Lebanon: A mixed-methods study.

INTRODUCTION: Low adherence to medications, specifically in patients with Diabetes (DM) and Hypertension (HTN), and more so in refugee settings, remains a major challenge to achieving optimum clinical control in these patients. We aimed at determining the self-reported medication adherence prevalence and its predictors and exploring reasons for low adherence among these patients. METHODS: A mixed-methods study was conducted at Médecins Sans Frontières non-communicable diseases primary care center in the Shatila refugee camp in Beirut, Lebanon in October 2018. Data were collected using the validated Arabic version of the 8-items Morisky Medication Adherence Scale (MMAS-8) concurrently followed by in-depth interviews to explore barriers to adherence in patients with DM and/or HTN. Predictors of adherence were separately assessed using logistic regression with SPSS© version 20. Manual thematic content analysis was used to analyze the qualitative data. RESULTS: Of the 361 patients included completing the MMAS, 70% (n = 251) were moderately to highly adherent (MMAS-8 score = 6 to 8), while 30% (n = 110) were low-adherent (MMAS-8 score<6). Patients with DM-1 were the most likely to be moderately to highly adherent (85%; n = 29). Logistic regression analysis showed that patients with a lower HbA1C were 75% more likely to be moderately to highly adherent [(OR = 0.75 (95%CI 0.63-0.89), p-value 0.001]. Factors influencing self-reported moderate and high adherence were related to the burden of the disease and its treatment, specifically insulin, the self-perception of the disease outcomes and the level of patient's knowledge about the disease and other factors like supportive family and healthcare team. CONCLUSION: Adherence to DM and HTN was good, likely due to a patient-centered approach along with educational interventions. Future studies identifying additional factors and means addressing the barriers to adherence specific to the refugee population are needed to allow reaching optimal levels of adherence and design well-informed intervention programs.

The socioeconomic burden of antibiotic resistance in conflict-affected settings and refugee hosting countries: a systematic scoping review.

BACKGROUND: Antibiotic resistance (ABR) is a major global threat. Armed and protracted conflicts act as multipliers of infection and ABR, thus leading to increased healthcare and societal costs. We aimed to understand and describe the socioeconomic burden of ABR in conflict-affected settings and refugee hosting countries by conducting a systematic scoping review. METHODS: A systematic search of PubMed, Medline (Ovid), Embase, Web of Science, SCOPUS and Open Grey databases was conducted to identify all relevant human studies published between January 1990 and August 2019. An updated search was also conducted in April 2020 using Medline/Ovid. Independent screenings of titles/abstracts followed by full texts were performed using pre-defined criteria. The Newcastle-Ottawa Scale was used to assess study quality. Data extraction and analysis were based on the PICOS framework and following the PRISMA-ScR guideline. RESULTS: The search yielded 8 studies (7 publications), most of which were single-country, mono-center and retrospective studies. The studies were conducted in Lebanon (n = 3), Iraq (n = 2), Jordan (n = 1), Palestine (n = 1) and Yemen (n = 1). Most of the studies did not have a primary aim to assess the socioeconomic impact of ABR and were small studies with limited statistical power that could not demonstrate significant associations. The included studies lacked sufficient information for the accurate evaluation of the cost incurred by antibiotic resistant infections in conflict-affected countries. CONCLUSION: This review highlights the scarcity of research on the socioeconomic burden of ABR on general populations in conflict-affected settings and on refugees and migrants in host countries, and lists recommendations for consideration in future studies. Further studies are needed to understand the cost of ABR in these settings to develop and implement adaptable policies.

Treating Syrian refugees with diabetes and hypertension in Shatila refugee camp, Lebanon: Médecins Sans Frontières model of care and treatment outcomes.

BACKGROUND: Médecins Sans Frontières (MSF) has been providing primary care for non-communicable diseases (NCDs), which have been increasing in low to middle-income countries, in the Shatila refugee camp, Beirut, Lebanon, using a comprehensive model of care to respond to the unmet needs of Syrian refugees. The objectives of this study were to: 1) describe the model of care used and the Syrian refugee population affected by diabetes mellitus (DM) and/or hypertension (HTN) who had ≥ one visit in the MSF NCD clinic in Shatila in 2017, and 2) assess 6 month treatment outcomes. METHODS: A descriptive retrospective cohort study using routinely collected program data for a model of care for patients with DM and HTN consisting of four main components: case management, patient support and education counseling, integrated mental health, and health promotion. RESULTS: Of 2644 Syrian patients with DM and/or HTN, 8% had Type-1 DM, 30% had Type-2 DM, 30% had HTN and 33% had DM + HTN. At intake, patients had a median age of 53, were predominantly females (63%), mostly from outside the catchment area (70%) and diagnosed (97%) prior to enrollment. After 6 months of care compared to intake: 61% of all patients had controlled DM (HbA1C < 8%) and 50% had controlled blood pressure (BP: < 140/90 mmHg) compared to 29 and 32%, respectively (p < 0.001). Compared to intake, patients with Type-1 DM reached an HbA1C mean of 8.4% versus 9.3% (p = 0.022); Type-2 DM patients had an HbA1C mean of 8.1% versus 9.4% (p = 0.001); and those with DM + HTN reached a mean HbA1C of 7.7% versus 9.0%, (p = 0.003). Reflecting improved control, HTN patients requiring ≥3 medications increased from 23 to 38% (p < 0.001), while DM patients requiring insulin increased from 21 to 29% (p < 0.001). Loss-to-follow-up was 16%. CONCLUSIONS: The MSF model of care for DM and HTN operating in the Shatila refugee camp is feasible, and showed promising outcomes among enrolled individuals. It may be replicated in similar contexts to respond to the increasing burden of NCDs among refugees in the Middle-East and elsewhere.

In vivo efficacy of artesunate-amodiaquine and artemether-lumefantrine for the treatment of uncomplicated falciparum malaria: an open-randomized, non-inferiority clinical trial in South Kivu, Democratic Republic of Congo.

BACKGROUND: Between 2009 and 2012, malaria cases diagnosed in a Médecins sans Frontières programme have increased fivefold in Baraka, South Kivu, Democratic Republic of the Congo (DRC). The cause of this increase is not known. An in vivo drug efficacy trial was conducted to determine whether increased treatment failure rates may have contributed to the apparent increase in malaria diagnoses. METHODS: In an open-randomized non-inferiority trial, the efficacy of artesunate-amodiaquine (ASAQ) was compared to artemether-lumefantrine (AL) for the treatment of uncomplicated falciparum malaria in 288 children aged 6-59 months. Included children had directly supervised treatment and were then followed for 42 days with weekly clinical and parasitological evaluations. The blood samples of children found to have recurring parasitaemia within 42 days were checked by PCR to confirm whether or not this was due to reinfection or recrudescence (i.e. treatment failure). RESULTS: Out of 873 children screened, 585 (67 %) were excluded and 288 children were randomized to either ASAQ or AL. At day 42 of follow up, the treatment efficacy of ASAQ was 78 % before and 95 % after PCR correction for re-infections. In the AL-arm, treatment efficacy was 84 % before and 99.0 % after PCR correction. Treatment efficacy after PCR correction was within the margin of non-inferiority as set for this study. Fewer children in the AL arm reported adverse reactions. CONCLUSIONS: ASAQ is still effective as a treatment for uncomplicated malaria in Baraka, South Kivu, DRC. In this region, AL may have higher efficacy but additional trials are required to draw this conclusion with confidence. The high re-infection rate in South-Kivu indicates intense malaria transmission. Trial registration NCT02741024.

Description of 3,180 courses of chelation with dimercaptosuccinic acid in children ≤ 5 y with severe lead poisoning in Zamfara, Northern Nigeria: a retrospective analysis of programme data.

BACKGROUND: In 2010, Médecins Sans Frontières (MSF) discovered extensive lead poisoning impacting several thousand children in rural northern Nigeria. An estimated 400 fatalities had occurred over 3 mo. The US Centers for Disease Control and Prevention (CDC) confirmed widespread contamination from lead-rich ore being processed for gold, and environmental management was begun. MSF commenced a medical management programme that included treatment with the oral chelating agent 2,3-dimercaptosuccinic acid (DMSA, succimer). Here we describe and evaluate the changes in venous blood lead level (VBLL) associated with DMSA treatment in the largest cohort of children ≤ 5 y of age with severe paediatric lead intoxication reported to date to our knowledge. METHODS AND FINDINGS: In a retrospective analysis of programme data, we describe change in VBLL after DMSA treatment courses in a cohort of 1,156 children ≤ 5 y of age who underwent between one and 15 courses of chelation treatment. Courses of DMSA of 19 or 28 d duration administered to children with VBLL ≥ 45 µg/dl were included. Impact of DMSA was calculated as end-course VBLL as a percentage of pre-course VBLL (ECP). Mixed model regression with nested random effects was used to evaluate the relative associations of covariates with ECP. Of 3,180 treatment courses administered, 36% and 6% of courses commenced with VBLL ≥ 80 µg/dl and ≥ 120 µg/dl, respectively. Overall mean ECP was 74.5% (95% CI 69.7%-79.7%); among 159 inpatient courses, ECP was 47.7% (95% CI 39.7%-57.3%). ECP after 19-d courses (n = 2,262) was lower in older children, first-ever courses, courses with a longer interval since a previous course, courses with more directly observed doses, and courses with higher pre-course VBLLs. Low haemoglobin was associated with higher ECP. Twenty children aged ≤ 5 y who commenced chelation died during the period studied, with lead poisoning a primary factor in six deaths. Monitoring of alanine transaminase (ALT), creatinine, and full blood count revealed moderate ALT elevation in <2.5% of courses. No clinically severe adverse drug effects were observed, and no laboratory findings required discontinuation of treatment. Limitations include that this was a retrospective analysis of clinical data, and unmeasured variables related to environmental exposures could not be accounted for. CONCLUSIONS: Oral DMSA was a pharmacodynamically effective chelating agent for the treatment of severe childhood lead poisoning in a resource-limited setting. Re-exposure to lead, despite efforts to remediate the environment, and non-adherence may have influenced the impact of outpatient treatment. Please see later in the article for the Editors' Summary.

Exposure to specific herbal products during pregnancy and the risk of low birth weight.

CONTEXT: Despite the fact that herbal products (HP) are used frequently during gestation worldwide, studies indicate that they may not be free of danger for fetuses. Evidence about the safety of HP use during pregnancy and their impact on pregnancy outcomes is currently lacking. OBJECTIVE: To quantify the association between HP use during the last 2 trimesters of pregnancy (≥15 weeks of gestation [WG]) and more specifically, between use of chamomile (Anthemis nobilis), flax (Linum usitatissimum), peppermint (M. balsamea), or green tea (Camellia sinensis) (alone or in combination with other HPs) and the risk of low birth weight (LBW). DESIGN: We evaluated data from the Quebec Pregnancy Registry, which was created by the linkage of 3 administrative databases in Quebec, and a self-administered questionnaire mailed to subjects. Participants 8505 women were randomly selected from the registry. Overall, 38.5% of women (n = 3273) returned their questionnaires, and 3183 were included in the study (8 were excluded because of missing values on birth weight or giving birth to twins or triplets). Outcome measures We performed a case-control analysis. Cases were defined as women who delivered a newborn <2500g and controls as women who delivered a newborn ≥2500g. Multivariate logistic regression models were used to analyze data. RESULTS: Amongst the selected 3183 participants, 424 (13.32%) were cases. After adjusting for potential confounders, no statistically significant associations were found between the use of any HP during the last 2 trimesters of pregnancy and the risk of LBW, or between the use of flax, chamomile, peppermint, or green tea (alone or in combination with other HPs) during the last 2 trimesters of pregnancy and the risk of LBW. CONCLUSION: HP use during the last 2 trimesters of pregnancy and more specifically, use of flax, chamomile, peppermint, or green tea alone or in combination with other HPs did not significantly increase the risk of LBW.

Review of endophthalmitis following Boston keratoprosthesis type 1.

Endophthalmitis remains one of the most damaging and challenging complications following Boston keratoprosthesis type 1 (KPro) surgery. The authors reviewed the literature from 2001 onward to identify cases of endophthalmitis following KPro surgery and present an additional case of endophthalmitis in a patient with Stevens Johnson syndrome. The prevalence of endophthalmitis between 2001 and 2011 was 5.4%. Gram-positive bacteria are the most common agents responsible for endophthalmitis in this patient population while gram-negative bacteria and fungi are emerging pathogens. Risk factors for endophthalmitis include preoperative diagnosis of cicatricial disease and postoperative infectious keratitis, glaucoma drainage device erosion and non-compliance with antibiotic prophylaxis. Additional studies on the prevention and treatment of endophthalmitis are required to improve the overall prognosis of these patients.

Prevalence, progression, and impact of glaucoma on vision after Boston type 1 keratoprosthesis surgery.

PURPOSE: To report glaucoma outcomes after Boston type 1 keratoprosthesis (KPro) surgery, in particular, glaucoma prevalence, progression, and treatment. DESIGN: Consecutive, retrospective, interventional case series. METHODS: setting: Tertiary care institution. study population: Thirty-eight eyes in 38 patients. intervention: KPro surgery. main outcome measures: Visual acuity (VA), intraocular pressure, visual fields, optic nerve status, and glaucoma treatment. RESULTS: Glaucoma diagnosis was known before surgery in 29 patients (76%; 14 had undergone previous surgery) and was diagnosed after surgery in 34 patients (89%) after a mean ± standard deviation of 16.5 ± 4.7 months of follow-up. The number of patients taking intraocular pressure-lowering medications increased from 19 (50%) before surgery to 28 (76%) after surgery (P = .017). Twenty-four patients (63%) were taking at least 1 additional glaucoma medication at their most recent postoperative visit. Eight patients (21%) had glaucoma progression (visual field progression, need for surgery, or both). Fifteen patients (40%) had a cup-to-disc ratio of 0.85 or more. Five patients required glaucoma surgery. VA was limited by glaucoma in 14 patients (37%), 11 of whom had a VA of 20/200 or worse. Five such patients (13%) had a dramatic improvement in VA, then progressed to end-stage glaucoma with fixation loss. Visual fields were limited by glaucoma in 25 patients (66%; mean Swedish Interactive Threshold Algorithm Fast mean defect, -20.3 ± 8.8 decibels; n = 18). CONCLUSIONS: Most KPro candidates have glaucoma, which may deteriorate in a subset of patients after surgery. Dramatic VA improvement after KPro surgery does not preclude the need for rigorous monitoring for glaucoma progression. A low threshold should be used to treat suspicion of even slightly elevated intraocular pressure.

Isotretinoin and the risk of cardiovascular, cerebrovascular and thromboembolic disorders.

BACKGROUND: Case reports suggest that isotretinoin use is associated with an increased risk of cardiovascular disorders; however, the clinical significance has not been determined. OBJECTIVE: To determine whether isotretinoin increases the risk of cardiovascular outcomes. METHODS: A case crossover study was performed among subjects who filled ≥1 isotretinoin prescription during 1984-2003. Cases were defined as those with a first-ever diagnosis or hospitalization for acute myocardial infarction (MI), stroke, phlebitis/thrombophlebitis, pulmonary embolism (PE) or thrombosis. Exposure to isotretinoin in a 5-month hazard period immediately prior to the index date (calendar date of the diagnosis or hospitalization for the study outcomes) was compared to a 5-month control period. Odds ratios (ORs) along with 95% confidence intervals (CIs) were estimated using conditional logistic regression. RESULTS: Of 30,496 isotretinoin users identified, 872 (3%) cases met the inclusion criteria; 381 (43.7%) had a stroke, 268 (30.7%) phlebitis/thrombophlebitis, 133 (15.3%) MI, 61 (7.0%) PE and 29 (3.3%) thrombosis. When stratified according to type of outcome, ORs were 0.75 (95% CI: 0.38-1.47), 1.31 (95% CI: 0.64-2.69) and 2.00 (95% CI: 0.50-8.00) for stroke, phlebitis/thrombophlebitis and MI, respectively. CONCLUSION: No statistically significant association was found between isotretinoin and cardiovascular, cerebrovascular and thromboembolic outcomes.

Antiepileptic drug use during pregnancy: perinatal outcomes.

PURPOSE: This study was undertaken to (1) measure the frequency of AED monotherapy or polytherapy during pregnancy and AED discontinuation prior to pregnancy in a cohort of women with treated epilepsy; and (2) describe the frequency of major congenital malformations according to maternal use of AED during pregnancy. METHODS: A cohort of epileptic pregnant women was identified within the Quebec Pregnancy Registry and was divided into three groups based on maternal AED use during pregnancy: AED monotherapy, AED polytherapy and no AED use. RESULTS: Of the 349 pregnancies meeting eligibility criteria, 79.6% were exposed to AED monotherapy and 5.8% to polytherapy during pregnancy; 14.6% discontinued AED prior to pregnancy. The most commonly used AEDs were carbamazepine (29.9%) and valproic acid (19.7%); the most common AED polytherapy combination was carbamazepine combined with clobazam (2.5%). Of 111 deliveries in the group of women on monotherapy during pregnancy, 9.9% (n=11) were born with major congenital malformations; in the group of women treated with polytherapy, 19.0% (n=8 over 42) of babies had major congenital malformations compared to 20.0% in women who discontinued AEDs prior to pregnancy. CONCLUSION: This study demonstrates that the majority of women suffering from epilepsy were treated with monotherapy rather than polytherapy during pregnancy. While most used other agents, an important number of women continued to use valproate in pregnancy despite the long standing evidence of its teratogenicity and increasing evidence of its neuro-toxicity to the fetus.

Herbal products use during pregnancy: prevalence and predictors.

PURPOSES: (1) Measure the prevalence of herbal product (HP) use, alone, and concomitantly with prescribed medications during pregnancy, (2) identify the most frequently consumed HP during gestation and (3) determine predictors of HP use at the beginning of pregnancy, and during the third trimester. METHODS: A questionnaire was mailed to 8505 women selected from the Quebec Pregnancy Registry which was created by the linkage of three administrative databases: RAMQ, Méd-Echo and ISQ. Women were eligible if they were continuously insured by the RAMQ drug plan for at least 12 months before the first day of gestation and during pregnancy, and if they gave birth to a live born between January 1998 and December 2003 in one of the Quebec's hospitals. Women with diabetes and psychoses, and women who delivered a baby with birth defects were selected first. Descriptive statistics and multivariate logistic regression models were used to analyse data. RESULTS: Of the 3354 women (39%) who answered the questionnaire, and were included in the study, nine per cent used HP during pregnancy. 69% of users took at least one prescribed medication concomitantly. Chamomile, green tea, peppermint and flax were the most frequently HP used. Multivariate analyses showed that body mass index (BMI), multivitamin use and one to three prescribed medications used before pregnancy were predictors of HP use at the beginning of pregnancy; adherent women, smokers and users of HP prior to pregnancy were predictors of HP use during the third trimester. CONCLUSION: HP use alone and concomitantly with prescribed medications during pregnancy is common, and needs to be addressed by health professionals.
