Eleven cystic fibrosis children (mean age, 9.6 years) were chosen at random to participate in a study to observe the effects of concurrently stimulating gastric/duodenal bicarbonate secretion and inhibiting gastric acid secretion, using a methylated prostaglandin E1 analogue in patients with pancreatic insufficiency and taking pancreatic enzymes. Percentage fat absorption in 3-day stool collections were calculated before and after commencing therapy with misoprostol, 400 μg/day in divided doses. We found a significant reduction in fat output (14.7 ± 11.7 versus 7.5 ± 3.5 g/day, p < 0.05) in the study group as a whole and a significant reduction in steatorrhoeic level as a percentage of fat intake in all of the patients with abnormal base-line collections (23.1% versus 9.2% p < 0.002). We conclude that misoprostol should be considered in cystic fibrosis patients with steatorrhoea as a means of improving nutrient absorption. © 1988 Informa UK Ltd All rights reserved: reproduction in whole or part not permitted.

BACKGROUND: Misoprostol is established for the treatment of incomplete abortion but has not been systematically assessed when provided by midwives at district level in a low-resource setting. We investigated the effectiveness and safety of midwives diagnosing and treating incomplete abortion with misoprostol, compared with physicians. METHODS: We did a multicentre randomised controlled equivalence trial at district level at six facilities in Uganda. Eligibility criteria were women with signs of incomplete abortion. We randomly allocated women with first-trimester incomplete abortion to clinical assessment and treatment with misoprostol either by a physician or a midwife. The randomisation (1:1) was done in blocks of 12 and was stratified for study site. Primary outcome was complete abortion not needing surgical intervention within 14-28 days after initial treatment. The study was not masked. Analysis of the primary outcome was done on the per-protocol population with a generalised linear-mixed effects model. The predefined equivalence range was -4% to 4%. The trial was registered at ClinicalTrials.gov, number NCT01844024. FINDINGS: From April 30, 2013, to July 21, 2014, 1108 women were assessed for eligibility. 1010 women were randomly assigned to each group (506 to midwife group and 504 to physician group). 955 women (472 in the midwife group and 483 in the physician group) were included in the per-protocol analysis. 452 (95·8%) of women in the midwife group had complete abortion and 467 (96·7%) in the physician group. The model-based risk difference for midwife versus physician group was -0·8% (95% CI -2·9 to 1·4), falling within the predefined equivalence range (-4% to 4%). The overall proportion of women with incomplete abortion was 3·8% (36/955), similarly distributed between the two groups (4·2% [20/472] in the midwife group, 3·3% [16/483] in the physician group). No serious adverse events were recorded. INTERPRETATION: Diagnosis and treatment of incomplete abortion with misoprostol by midwives is equally safe and effective as when provided by physicians, in a low-resource setting. Scaling up midwives' involvement in treatment of incomplete abortion with misoprostol at district level would increase access to safe post-abortion care.

OBJECTIVE: This study aimed to assess women´s acceptability of diagnosis and treatment of incomplete abortion with misoprostol by midwives, compared with physicians. METHODS: This was an analysis of secondary outcomes from a multi-centre randomized controlled equivalence trial at district level in Uganda. Women with first trimester incomplete abortion were randomly allocated to clinical assessment and treatment with misoprostol by a physician or a midwife. The randomisation (1:1) was done in blocks of 12 and stratified for health care facility. Acceptability was measured in expectations and satisfaction at a follow up visit 14-28 days following treatment. Analysis of women's overall acceptability was done using a generalized linear mixed-effects model with an equivalence range of -4% to 4%. The study was not masked. The trial is registered at ClinicalTrials.org, NCT 01844024. RESULTS: From April 2013 to June 2014, 1108 women were assessed for eligibility of which 1010 were randomized (506 to midwife and 504 to physician). 953 women were successfully followed up and included in the acceptability analysis. 95% (904) of the participants found the treatment satisfactory and overall acceptability was found to be equivalent between the two study groups. Treatment failure, not feeling calm and safe following treatment, experiencing severe abdominal pain or heavy bleeding following treatment, were significantly associated with non-satisfaction. No serious adverse events were recorded. CONCLUSIONS: Treatment of incomplete abortion with misoprostol by midwives and physician was highly, and equally, acceptable to women. TRIAL REGISTRATION: ClinicalTrials.gov NCT01844024.

Foi investigada a associação entre a utilização pré-natal de medicamentos com finalidade profilática, terapêutica e não-terapêutica e desfechos adversos da gravidez. Foram analisadas as evidências sobre o potencial teratogênico do misoprostol, por meio de revisão sistemática e metanálise de estudos de caso-controle. A partir da base de dados do Estudo Brasileiro de Diabetes Gestacional (EBDG), uma coorte multicêntrica de gestantes atendidas pelo Sistema Único de Saúde em seis capitais brasileiras, foi analisada a associação entre o uso referido de medicamentos para induzir a menstruação e desfechos adversos perinatais, incluindo anomalias congênitas, morte intra-uterina e nascimento pré-termo. O uso referido e prescrito de sais de ferro, isolado ou associado a vitaminas, foi analisado quanto aos riscos e benefícios da utilização profilática ou terapêutica em relação a nascimento pré-termo e baixo peso ao nascer. Quatro estudos envolvendo 4899 casos de anomalias congênitas e 5742 controles foram incluídos na revisão sistemática de acordo com os critérios de seleção. Nenhum estudo analisou outros efeitos adversos do misoprostol no resultado da gestação. Foi estimado um risco aumentado de anomalia congênita associada ao uso de misoprostol para qualquer defeito congênito (RC= 3,56; IC 95% 0,98 – 12,98), seqüência de Moebius (RC= 25,31; IC 95%11,11 – 57,66) e redução transversa de membros (RC=11,86; IC 95% 4,86 – 28,90). Entre as 4856 gestantes estudadas a partir da base de dados do EBDG, 707 (14,6%) relataram o uso de substâncias para induzir a menstruação, das quais as mais citadas foram chás, hormônios sexuais e misoprostol. Foi verificada associação positiva entre misoprostol e anomalias congênitas ajustado para centro de realização da pesquisa (RC 2,64: IC 95% 1,03 – 6,75). Foi detectada associação positiva entre o uso de hormônios sexuais e anomalias congênitas (RC 2,24; IC 95% 1,06 – 4,74), independente do centro de realização da pesquisa. Para os desfechos morte intra-uterina e nascimento pré-termo, não foi verificada qualquer associação com o uso de misoprostol, hormônios sexuais ou chás. Entre as 3865 gestantes estudadas quanto ao uso de sais de ferro durante a gestação, 805 (20,8%) referiram o uso de sais de ferro isolado e 1136 (29,4%) ferro associado a vitaminas. O uso prescrito de sais de ferro isolado foi verificado para 1973 gestantes (51,0%) e de ferro vi associado a vitaminas prescrito para 890 (23%). A prevalência de anemia foi de 31,3%. Entre as gestantes anêmicas, 70,9% utilizavam sais de ferro e entre as não-anêmicas, o percentual foi de 51,5%. Após ajustamento para potenciais confundidores, o uso prescrito de sais de ferro isolado apresentou associação negativa para nascimento pré-termo em gestantes anêmicas (RC 0,57 IC 95% 0,40 – 0,80) mas não em gestantes não-anêmicas. Para as demais exposições analisadas, não foi verificado qualquer associação. Não foi detectada associação entre o uso de sais de ferro e/ou vitaminas e baixo peso ao nascer. Os resultados apresentados indicam que o uso de misoprostol em gestações que não se perdem está associado a um maior risco de anomalias congênitas, em geral, e de Seqüência de Moebius e redução transversa de membros, em particular. O uso terapêutico de sais de ferro em gestantes anêmicas mostrou associação negativa para nascimento pré-termo. Entretanto, o uso de sais de ferro em gestantes não anêmicas não mostrou relação com os desfechos analisados.

Objective. The purpose of this study was to evaluate the effectiveness and safety of misoprostol in two different formulations: vaginal tablets of 25 mu g and one-eighth of a 200-mu g oral tablet, also administered intravaginally, for cervical ripening and labor induction of term pregnancies with an indication for that. Methods. A single-blind, randomized, controlled clinical trial was carried out in 120 pregnant women who randomly received one of the two formulations. The main dependent variables were mode of delivery, need for additional oxytocin, time between beginning of induction and delivery, perinatal results, complications, and maternal side effects. Student's t, Mann-Whitney, chi(2), Fisher's Exact, Wilcoxon and Kolmogorov-Smirnoff tests, as well as survival analysis, were used in the data analysis. Results. There were no significant differences between the groups in terms of general characteristics, uterine contractility, and fetal well-being during labor, cesarean section rates, perinatal outcomes, or maternal adverse events. The mean time between the beginning of cervical ripening and delivery was 31.3 h in the vaginal tablet group and 30.1 h in the oral tablet group, a difference that was not statistically significant. Conclusion. The results showed that the 25-mu g vaginal tablets of misoprostol were as effective and safe for cervical ripening and labor induction as the dose-equivalent fraction of 200-mu g oral tablets.

OBJECTIVE: To compare the efficacy of vaginal misoprostol versus dinoprostone for induction of labor (IOL) in patients with preeclampsia according to the WHO criteria. STUDY DESIGN: Ninety-eight patients were retrospectively analyzed. A total of 47 patients received 3 mg dinoprostone suppositories every 6 h (max. 6 mg/24 h) whereas 51 patients in the misoprostol group received either 50 mug misoprostol vaginally every 12 h, or 25 mug every 6 h (max. 100 mug/24 h). Primary outcomes were vaginal delivery within 24 and 48 h, respectively. RESULTS: The probability of delivering within 48 h was more than three-fold higher in the misoprostol than in the dinoprostone group: odds ratio (OR)=3.48; 95% confidence interval (CI) 1.24, 10.30, whereas no significant difference was observed within 24 h (P=0.34). No correlation was seen between a ripe cervix prior to IOL and delivery within 24/48 h (P=0.33 and P=1.0, respectively). More cesarean sections were performed in the dinoprostone group due to failed IOL (P=0.0009). No significant differences in adverse maternal outcome were observed between both study groups, whereas more neonates (12 vs. 6) of the dinoprostone group were admitted to the NICU (P=0.068). CONCLUSION: This study suggests that misoprostol may have some advantages compared to dinoprostone, including improved efficacy and lower cost of the drug, even in cases of preeclampsia.

OBJECTIVE: To investigate whether orally administered misoprostol during the third stage of labor is efficient in reducing postpartum blood loss. METHODS: In a double-masked trial, during vaginal delivery women were randomly assigned to receive a single oral dose of misoprostol (600 microg) or placebo in third stage of labor, immediately after cord clamping. The third stage of labor was managed routinely by early cord clamping and controlled cord traction; oxytocin was administered only if blood loss seemed more than usual. Blood loss was estimated by the delivering physician and differences in hematocrit were measured before and after delivery. RESULTS: Mean (+/- standard error of the mean) estimated blood loss (345 +/- 19.5 mL versus 417 +/- 25.9 mL, P = .031) and hematocrit difference (4.5 +/- 0.9% versus 7.9 +/- 1.2%, P = .014) were significantly lower in women who received misoprostol than those who received placebo. Fewer women in the misoprostol group had postpartum hemorrhage (blood loss of at least 500 mL), but that difference was not statistically significant (7% versus 15%, P = .43). Additional oxytocin before or after placental separation was used less often in the misoprostol group (16% versus 38%, P = .047). There were no differences in the length of third stage of labor (8 +/- 0.9 minutes versus 9 +/- 1 minutes, P = .947). There were no differences in pain during third stage of labor, postpartum fever, or diarrhea, but shivering was more frequent in the misoprostol group. CONCLUSION: Oral misoprostol administered in the third stage of labor reduced postpartum blood loss and might be effective in reducing incidence of postpartum hemorrhage.
