Bartter syndrome-like phenotype in a patient with type 2 diabetes mellitus.

Bartter syndrome (BS) is a rare genetic tubulopathy affecting the loop of Henle leading to salt wasting. It is commonly seen in utero or in the early neonatal period. Rare cases of acquired BS are reported in association with infections like tuberculosis, granulomatous conditions like sarcoidosis, autoimmune diseases and drugs. The mainstay of management includes potassium, calcium and magnesium supplementation. We report the case of a woman in her 50s with a history of type 2 diabetes mellitus for the last 10 years, who presented with diabetic foot ulcers and generalised weakness with ECG changes suggestive of hypokalaemia. She had severe hypokalaemia with high urine potassium excretion and hypochloraemic metabolic alkalosis. She poorly responded to intravenously administered potassium supplements and had persistent hypokalaemia. On further evaluation of the persistent hypokalaemia, a diagnosis of idiopathic Bartter-like phenotype was made. She responded well to tablet indomethacin and is presently asymptomatic and is being maintained on tablet indomethacin after 6 months of follow-up.

Long-Term Indomethacin Treatment in a Chinese Child with Gitelman Syndrome: Case Report and Literature Review on its Efficacy and Tolerance.

BACKGROUND Gitelman syndrome (GS) is a rare inherited autosomal recessive salt-losing renal tubulopathy. Early-onset GS is difficult to differentiate from Bartter syndrome (BS). It has been reported in some cases that cyclooxygenase (COX) inhibitors, which pharmacologically reduce prostaglandin E2(PGE2) synthesis, are helpful for GS patients, especially in children, but the long-term therapeutic effect has not yet been revealed. CASE REPORT A 4-year-old boy was first brought to our hospital for the chief concern of short stature and growth retardation. Biochemical tests demonstrated severe hypokalemia, hyponatremia, and hypochloremic metabolic alkalosis. The patient's serum magnesium was normal. He was diagnosed with BS and treated with potassium supplementation and indomethacin and achieved stable serum potassium levels and slow catch-up growth. At 11.8 years of age, the patient showed hypomagnesemia and a genetic test confirmed that he had GS with compound heterozygous mutations in the SLC12A3 gene. At the age of 14.8 years, when indomethacin had been taken for nearly 10 years, the boy reported having chronic stomachache, while his renal function remained normal. After proton pump inhibitor and acid inhibitor therapy, the patient's symptoms were ameliorated, and he continued to take a low dose of indomethacin (37.5 mg/d divided tid) with good tolerance. CONCLUSIONS Early-onset GS in childhood can be initially misdiagnosed as BS, and gene detection can confirm the final diagnosis. COX inhibitors, such as indomethacin, might be tolerated by pediatric patients, and long-term therapy can improve the hypokalemia and growth retardation without significant adverse effects.

Gastroprotective and ulcer healing effects of Nauclea pobeguinii (Rubiaceae) on experimentally induced gastric ulcers in male Wistar rats.

OBJECTIVES: In this study, we determined the gastroprotective and ulcer-healing effects of extracts (aqueous and methanolic) of Nauclea pobeguinii stem-back. METHODS: Gastroprotective and healing activity were evaluated following a HCl/ethanol and an indomethacin-induced acute ulcers models; acetic acid, pylorus-ligature, pylorus ligature/histamine and pylorus ligature/acetylcholine-induced chronic ulcers models. RESULTS: It emerges from this study that, at 100, 200 and 400 mg/kg, the extracts significantly reduced the various ulceration parameters. Compared to negative control male rats, the aqueous (100 mg/kg) and methanolic (400 mg/kg) extracts of Nauclea pobeguinii inhibited the ulcers induced by HCl/ethanol by 80.76 % and 100 % respectively, as well as ulcers induced by indomethacin by 88.28 % and 93.47 % respectively. Animals that received 200 mg/kg of both extracts showed a significant reduction in the levels of monocytes, lymphocytes, nitric oxide, MDA and a significant increase in the activities of SOD and catalase. Histological analysis showed repaired mucous epithelium at all doses of both extracts. Aqueous and methanol extracts inhibited ulceration indices by 89.33 % and 88.53 % for pylorus ligature, 83.81 % and 61.07 % for pylorus ligature/acetylcholine and 87.29 % and 99.63 % for pylorus ligature/histamine respectively. Both extracts protected the stomach lining with percentages inhibition of 79.49 % and 81.73 %, respectively in the ethanol test. The extracts induced a significant increase in mucus mass (p<0.001). CONCLUSIONS: The aqueous and methanol extracts of Nauclea pobeguinii healed ulcers thanks to their anti-inflammatory, anti-oxidant, anti-secretory and cytoprotective properties.

Phytochemical Estimation and Therapeutic Amelioration of Aesculus hippocastanum L. Seeds Ethanolic Extract in Gastric Ulcer in Rats Possibly by Inhibiting Prostaglandin Synthesis.

OBJECTIVE: To quantify phytochemicals using liquid chromatography and mass spectroscopy (LCMS) analysis and explore the therapeutic effect of Aesculus hippocastanum L. (AH) seeds ethanolic extract against gastric ulcers in rats. METHODS: Preliminary phytochemical testing and LCMS analysis were performed according to standard methods. For treatment, the animals were divided into 7 groups including normal control, ulcer control, self-healing, AH seeds low and high doses, ranitidine and per se groups. Rats were orally administered with 10 mg/kg of indomethacin, excluding the normal control group (which received 1% carboxy methyl cellulose) and the per se group (received 200 mg/kg AH seeds extract). The test group rats were then given 2 doses of AH seeds extract (100 and 200 mg/kg, respectively), while the standard group was given ranitidine (50 mg/kg). On the 11th day, rats in all groups were sacrificed, and their stomach was isolated to calculate the ulcer index, and other parameters such as blood prostaglandin (PGE2), tissue superoxide dismutase (SOD), catalase (CAT), malonyldialdehyde (MDA), and glutathione (GSH). All isolated stomach tissues were analyzed for histopathological findings. RESULTS: The phytochemical examination shows that the AH seeds contain alkaloids, flavonoids, saponins, phenolic components, and glycosides. LCMS analysis confirms the presence of quercetin and rutin. The AH seeds extract showed significant improvement in gastric mucosa conditions after indomethacin-induced gastric lesions (P<0.01). Further marked improvement in blood PGE2 and antioxidant enzymes, SOD, CAT, MDA and GSH, were observed compared with self-healing and untreated ulcer-induced groups (P<0.01). Histopathology results confirmed that AH seeds extract improved the mucosal layer and gastric epithelial membrane in treated groups compared to untreated ulcer-induced groups. CONCLUSIONS: LCMS report confirms the presence of quercetin and rutin in AH seeds ethanolic extract. The therapeutic effect of AH seeds extract against indomethacin-induced ulcer in rat model indicated the regenerated membrane integrity, with improved cellular functions and mucus thickness. Further, improved antioxidant enzyme level would help to reduce PGE2 biosynthesis.

Interventions for patent ductus arteriosus (PDA) in preterm infants: an overview of Cochrane Systematic Reviews.

BACKGROUND: Patent ductus arteriosus (PDA) is associated with significant morbidity and mortality in preterm infants. Several non-pharmacological, pharmacological, and surgical approaches have been explored to prevent or treat a PDA. OBJECTIVES: To summarise Cochrane Neonatal evidence on interventions (pharmacological or surgical) for the prevention of PDA and related complications, and interventions for the management of asymptomatic and symptomatic PDA in preterm infants. METHODS: We searched the Cochrane Database of Systematic Reviews on 20 October 2022 for ongoing and published Cochrane Reviews on the prevention and treatment of PDA in preterm (< 37 weeks' gestation) or low birthweight (< 2500 g) infants. We included all published Cochrane Reviews assessing the following categories of interventions: pharmacological therapy using prostaglandin inhibitor drugs (indomethacin, ibuprofen, and acetaminophen), adjunctive pharmacological interventions, invasive PDA closure procedures, and non-pharmacological interventions. Two overview authors independently checked the eligibility of the reviews retrieved by the search, and extracted data from the included reviews using a predefined data extraction form. Any disagreements were resolved by discussion with a third overview author. Two overview authors independently assessed the methodological quality of the included reviews using the AMSTAR 2 (A MeaSurement Tool to Assess systematic Reviews) tool. We reported the GRADE certainty of evidence as assessed by the respective review authors using summary of findings tables. MAIN RESULTS: We included 16 Cochrane Reviews, corresponding to 138 randomised clinical trials (RCT) and 11,856 preterm infants, on the prevention and treatment of PDA in preterm infants. One of the 16 reviews had no included studies, and therefore, did not contribute to the results. Six reviews reported on prophylactic interventions for the prevention of PDA and included pharmacological prophylaxis with prostaglandin inhibitor drugs, prophylactic surgical PDA ligation, and non-pharmacologic interventions (chest shielding during phototherapy and restriction of fluid intake); one review reported on the use of indomethacin for the management of asymptomatic PDA; nine reviews reported on interventions for the management of symptomatic PDA, and included pharmacotherapy with prostaglandin inhibitor drugs in various routes and dosages, surgical PDA ligation, and adjunct therapies (use of furosemide and dopamine in conjunction with indomethacin). The quality of reviews varied. Two reviews were assessed to be high quality, seven reviews were of moderate quality, five of low quality, while two reviews were deemed to be of critically low quality. For prevention of PDA, prophylactic indomethacin reduces severe intraventricular haemorrhage (IVH; relative risk (RR) 0.66, 95% confidence interval (CI) 0.53 to 0.82; 14 RCTs, 2588 infants), and the need for invasive PDA closure (RR 0.51, 95% CI 0.37 to 0.71; 8 RCTs, 1791 infants), but it does not appear to affect the composite outcome of death or moderate/severe neurodevelopmental disability (RR 1.02, 95% CI 0.90 to 1.15; 3 RCTs, 1491 infants). Prophylactic ibuprofen probably marginally reduces severe IVH (RR 0.67, 95% CI 0.45 to 1.00; 7 RCTs, 925 infants; moderate-certainty evidence), and the need for invasive PDA closure (RR 0.46, 95% CI 0.22 to 0.96; 7 RCTs, 925 infants; moderate-certainty evidence). The evidence is very uncertain on the effect of prophylactic acetaminophen on severe IVH (RR 1.09, 95% CI 0.07 to 16.39; 1 RCT, 48 infants). Necrotising enterocolitis (NEC) was lower with both prophylactic surgical ligation (RR 0.25, 95% CI 0.08 to 0.83; 1 RCT, 84 infants), and fluid restriction (RR 0.43, 95% CI 0.21 to 0.87; 4 RCTs, 526 infants). For treatment of asymptomatic PDA, indomethacin appears to reduce the development of symptomatic PDA post-treatment (RR 0.36, 95% CI 0.19 to 0.68; 3 RCTs, 97 infants; quality of source review: critically low). For treatment of symptomatic PDA, all available prostaglandin inhibitor drugs appear to be more effective in closing a PDA than placebo or no treatment (indomethacin: RR 0.30, 95% CI 0.23 to 0.38; 10 RCTs, 654 infants; high-certainty evidence; ibuprofen: RR 0.62, 95% CI 0.44 to 0.86; 2 RCTs, 206 infants; moderate-certainty evidence; early administration of acetaminophen: RR 0.35, 95% CI 0.23 to 0.53; 2 RCTs, 127 infants; low-certainty evidence). Oral ibuprofen appears to be more effective in PDA closure than intravenous (IV) ibuprofen (RR 0.38, 95% CI 0.26 to 0.56; 5 RCTs, 406 infants; moderate-certainty evidence). High-dose ibuprofen appears to be more effective in PDA closure than standard-dose ibuprofen (RR 0.37, 95% CI 0.22 to 0.61; 3 RCTs, 190 infants; moderate-certainty evidence). With respect to adverse outcomes, compared to indomethacin administration, NEC appears to be lower with ibuprofen (any route; RR 0.68, 95% CI 0.49 to 0.94; 18 RCTs, 1292 infants; moderate-certainty evidence), oral ibuprofen (RR 0.41, 95% CI 0.23 to 0.73; 7 RCTs, 249 infants; low-certainty evidence), and with acetaminophen (RR 0.42, 95% CI 0.19 to 0.96; 4 RCTs, 384 infants; low-certainty evidence). However, NEC appears to be increased with a prolonged course of indomethacin versus a shorter course (RR 1.87, 95% CI 1.07 to 3.27; 4 RCTs, 310 infants). AUTHORS' CONCLUSIONS: This overview summarised the evidence from 16 Cochrane Reviews of RCTs regarding the effects of interventions for the prevention and treatment of PDA in preterm infants. Prophylactic indomethacin reduces severe IVH, but does not appear to affect the composite outcome of death or moderate/severe neurodevelopmental disability. Prophylactic ibuprofen probably marginally reduces severe IVH (moderate-certainty evidence), while the evidence is very uncertain on the effect of prophylactic acetaminophen on severe IVH. All available prostaglandin inhibitor drugs appear to be effective in symptomatic PDA closure compared to no treatment (high-certainty evidence for indomethacin; moderate-certainty evidence for ibuprofen; low-certainty evidence for early administration of acetaminophen). Oral ibuprofen appears to be more effective in PDA closure than IV ibuprofen (moderate-certainty evidence). High dose ibuprofen appears to be more effective in PDA closure than standard-dose ibuprofen (moderate-certainty evidence). There are currently two ongoing reviews, one on fluid restriction for symptomatic PDA, and the other on invasive management of PDA in preterm infants.

Exploration of molecular mechanisms responsible for anti-inflammatory and anti-angiogenic attributes of methanolic extract of Viola betonicifolia.

Uncontrolled inflammation plays a central role in the pathogenesis of various diseases. Currently available anti-inflammatory agents on prolonged use may lead to ulcers or thrombus formation. The present study was designed to evaluate the anti-inflammatory, anti-arthritic and anti-angiogenic potentials of methanol extract of Viola betonicifolia using battery of in vivo models. Methanol extract of Viola betonicifolia (Vb.Me) was prepared through maceration. High performance liquid chromatography (HPLC) and gas chromatography mass spectrometery (GC-MS) were performed to identify bioactive compounds present in Vb.Me. In vivo safety profile of Vb.Me was evaluated following OECD 425 acute toxicity guidelines. Anti-inflammatory potential of Vb.Me at three different dose levels was evaluated in in vivo acute (carrageenan and, histamine-induced paw oedema), sub-chronic (cotton pellet-induced granuloma) and chronic (Complete Freund's adjuvant-induced arthritis) models. Blood and paws samples were collected to study effects of Vb.Me treatment on the expression of various pro- and anti-inflammatory genes (RT-PCR) and to study the histopathological changes at tissue levels. Effects of Vb.Me on neovasculature development were studied in ex-ovo chicken chorioallantoic membrane (CAM) assay. Quercetin and n-hexadecanoic were identified as one of the major bioactive molecules in HPLC and GC-MS analysis of Vb.Me. Toxicity data revealed that Vb.Me was safe for administration up to the dose of 2000 mg/kg. Findings of inflammatory models showed that Vb.Me produced time and dose-dependent effects. 500 mg/kg Vb.Me showed significantly (p < 0.05) better effects as compared with 125 and 250 mg/kg. 500 mg/kg Vb.Me also showed comparable anti-inflammatory effects with indomethacin in both acute and chronic models respectively. RT-PCR data exhibited significant (p < 0.05) down-regulation of IL-6, IL-1ß, NF-kß, TNF-α and COX-2 genes with simultaneous up-regulation of IL-4 and IL-10 genes in the blood samples of animals treated with 500 mg/kg of Vb.Me and 10 mg/kg of indomethacin respectively. CAM assay data revealed arrest of microvessel outgrowth in Vb.Me-treated eggs. Altogether, findings of the current study indicate that Vb.Me exerts in vivo anti-inflammatory and anti-angiogenic effects through regulation of expression of various pro- and anti-inflammatory genes. Synergist actions of various bioactive molecules in Vb.Me are proposed to be responsible for these attributes. However, further studies to standardize the extract and evaluation of its potential in various inflammation-induced diseases are warranted.

Four kinds of tocolytic therapy for preterm delivery: Systematic review and network meta-analysis.

WHAT IS KNOWN AND OBJECTIVE: Premature birth affects more than 15 million infants, as well as mothers and families around the world. With the relaxation of the two-child policy, the problem of premature birth has become relatively prominent in China. According to statistics, China had a birth population of 15.23 million in 2018, with a considerably large number of premature births. This study aims to evaluate the efficacy and safety of tocolysis in the treatment of preterm delivery, provide clinical evidence for medical staff and promote the self-management of patients with premature births. METHODS: Four English databases (PubMed, Embase, Cochrane Library and Web of Science) were retrieved by computer, the retrieval time was from the establishment of each database to November 2021, and the randomized controlled trials for the treatment of preterm delivery were screened according to the pre-set natriuretic exclusion criteria. After literature screening, data selection and risk of bias evaluation were independently conducted by two researchers. R 4.1.1 and Stata 17.0 software were used for statistical analysis. RESULTS AND DISCUSSION: A total of 44 RCTs were included, including 6939 patients. The results of network meta-analysis reveal that in terms of effectiveness, indomethacin was the most effective intervention measure, followed by nifedipine, and the difference was statistically significant; regarding safety, nifedipine was the safest intervention measure, followed by indomethacin, and the difference was statistically significant; and in respect of adverse reactions, ritodrine had the highest probability, and the difference was statistically significant. WHAT IS NEW AND CONCLUSION: Nifedipine may be better for delayed delivery and less likely to produce adverse pregnancy outcomes, followed by indomethacin. Limited by the number and quality of recipient studies, the aforementioned conclusions need to be verified through more high-quality studies. At the same time, the focus should be on patients with twin pregnancy and patients with clinical manifestations of extreme preterm delivery.

Retrospective Study of Outcomes and Hospitalization Rates of Patients in Italy with a Confirmed Diagnosis of Early COVID-19 and Treated at Home Within 3 Days or After 3 Days of Symptom Onset with Prescribed and Non-Prescribed Treatments Between November 2020 and August 2021.

BACKGROUND This retrospective study aimed to investigate outcomes and hospitalization rates in patients with a confirmed diagnosis of early COVID-19 treated at home with prescribed and non-prescribed treatments. MATERIAL AND METHODS The medical records of a cohort of 158 Italian patients with early COVID-19 treated at home were analyzed. Treatments consisted of indomethacin, low-dose aspirin, omeprazole, and a flavonoid-based food supplement, plus azithromycin, low-molecular-weight heparin, and betamethasone as needed. The association of treatment timeliness and of clinical variables with the duration of symptoms and with the risk of hospitalization was evaluated by logistic regression. RESULTS Patients were divided into 2 groups: group 1 (n=85) was treated at the earliest possible time (<72 h from onset of symptoms), and group 2 (n=73) was treated >72 h after the onset of symptoms. Clinical severity at the beginning of treatment was similar in the 2 groups. In group 1, symptom duration was shorter than in group 2 (median 6.0 days vs 13.0 days, P<0.001) and no hospitalizations occurred, compared with 19.18% hospitalizations in group 2. One patient in group 1 developed chest X-ray alterations and 2 patients experienced an increase in D-dimer levels, compared with 30 and 22 patients, respectively, in group 2. The main factor determining the duration of symptoms and the risk of hospitalization was the delay in starting therapy (P<0.001). CONCLUSIONS This real-world study of patients in the community showed that early diagnosis and early supportive patient management reduced the severity of COVID-19 and reduced the rate of hospitalization.

The effectiveness of nifedipine/indomethacin combination therapy and nifedipine monotherapy for postponing preterm birth (25-34 weeks of gestation) in Sudanese women: a randomized clinical trial study protocol.

BACKGROUND: Preterm birth is the most common cause of neonatal morbidity and mortality. Tocolytics are considered a standard treatment for women with threatened preterm delivery to allow time for maternal steroid administration and transfer to referral centers with neonatal intensive care units. However, there is controversy about the best tocolytic therapy to be considered as the first choice. The aim of this study is to compare the tocolytic effectiveness and tolerability of combination therapy with nifedipine and indomethacin versus nifedipine monotherapy among Sudanese women with preterm labor (PTL) as well as to compare the possible neonatal outcomes associated with each drug. METHODS/DESIGN: This is a randomized controlled clinical trial to be conducted in the Medani Maternity Hospital, Sudan. Women aged 18-40 years that are diagnosed with preterm labor and have a gestational age between 25 and 34 weeks will be eligible to participate in this trial. The diagnosis of threatened PTL is defined as persistent uterine contractions "(four contractions every 20 min or eight contractions every 60 min)" with cervical changes "(cervical effacement ≤80% or cervical dilatation >two cm)". Patients will be eligible regardless of the presentation of the fetus. It will be randomly decided whether participants receive nifedipine/indomethacin combination therapy or nifedipine monotherapy. The primary outcome is the number of women who do not deliver and do not need alternative tocolytic drug (terbutaline). The secondary outcome is an estimated association with neonatal morbidity and mortality. The sample size will be 117 subjects in each arm of the study, according to a type I error of 0.05 and a study power of 80%. DISCUSSION: We expect higher effectiveness of the combination indomethacin/nifedipine tocolytic therapy compared with nifedipine monotherapy. We plan to suggest this combination therapy as the best option for postponing PTL. TRIAL REGISTRATION: Clinical trial registration: PACTR202004681537890 , date of registration: March 8, 2020.

Use of ibuprofen for the closure of patent ductus arteriosus in preterm infants: a systematic review of meta-analyses.

Aim: To systematically review ibuprofen, including versus indomethacin and paracetamol/acetaminophen, for the closure of patent ductus arteriosus (PDA). Methods: Pubmed, Embase, Cochrane and gray literature were searched to summarize ibuprofen outcomes in closure of PDA in published meta-analyses (MAs). Results: Seven MAs were included. Including high dose (HD) use, ibuprofen is equivalent/superior to indomethacin, and inferior/equivalent to paracetamol. Oral ibuprofen had higher efficacy than IV ibuprofen, including compared with indomethacin and paracetamol. Ibuprofen had safety advantages over indomethacin. Indomethacin and paracetamol had safety advantages over IV ibuprofen. HD of ibuprofen increases efficacy, but not toxicity. Conclusion: Evidence on ibuprofen effectiveness and safety, including the dosage forms, is limited by heterogeneity in doses and the levels of methods quality and risk of bias.

Advances in Management for Preterm Fetuses at Risk of Delivery.

Preterm birth accounts for only 11% of live births but contributes to up to 75% of neonatal mortality and more than half of long-term morbidity. Targeted interventions to reduce the most common causes of perinatal morbidity and mortality include intrapartum group B Streptococcus prophylaxis, magnesium sulfate for fetal neuroprotection, antenatal corticosteroids for fetal lung maturity, latency antibiotics for preterm premature rupture of membranes, and tocolysis to allow corticosteroid administration and transfer to a tertiary care center. This article reviews the evidence for interventions to improve outcomes for fetuses at risk for preterm delivery at different gestational ages.

Cervical stitch (cerclage) in combination with other treatments for preventing spontaneous preterm birth in singleton pregnancies.

BACKGROUND: Preterm birth (PTB) remains the foremost global cause of perinatal morbidity and mortality. Thus, the prevention of spontaneous PTB still remains of critical importance. In an attempt to prevent PTB in singleton pregnancies, cervical cerclage, in combination with other treatments, has been advocated. This is because, cervical cerclage is an intervention that is commonly recommended in women with a short cervix at high risk of preterm birth but, despite this, many women still deliver prematurely, as the biological mechanism is incompletely understood. Additionally, previous Cochrane Reviews have been published on the effectiveness of cervical cerclage in singleton and multiple pregnancies, however, none has evaluated the effectiveness of using cervical cerclage in combination with other treatments. OBJECTIVES: To assess whether antibiotics administration, vaginal pessary, reinforcing or second cerclage placement, tocolytic, progesterone, or other interventions at the time of cervical cerclage placement prolong singleton gestation in women at high risk of pregnancy loss based on prior history and/or ultrasound finding of 'short cervix' and/or physical examination. History-indicated cerclage is defined as a cerclage placed usually between 12 and 15 weeks gestation based solely on poor prior obstetrical history, e.g. multiple second trimester losses due to painless dilatation. Ultrasound-indicated cerclage is defined as a cerclage placed usually between 16 and 23 weeks gestation for transvaginal ultrasound cervical length < 20 mm in a woman without cervical dilatation. Physical exam-indicated cerclage is defined as a cerclage placed usually between 16 and 23 weeks gestation because of cervical dilatation of one or more centimetres detected on physical (manual) examination. SEARCH METHODS: We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov and the WHO International Clinical Trials Registry Platform (ICTRP) (26 September 2019), and reference lists of retrieved studies. SELECTION CRITERIA: We included published, unpublished or ongoing randomised controlled trial (RCTs). Studies using a cluster-RCT design were also eligible for inclusion in this review but none were identified. We excluded quasi-RCTs (e.g. those randomised by date of birth or hospital number) and studies using a cross-over design. We also excluded studies that specified addition of the combination therapy after cervical cerclage because the woman subsequently became symptomatic. We included studies comparing cervical cerclage in combination with one, two or more interventions with cervical cerclage alone in singleton pregnancies. DATA COLLECTION AND ANALYSIS: Two review authors independently screened titles and abstracts of all retrieved articles, selected studies for inclusion, extracted data, assessed risk of bias, and evaluated the certainty of the evidence for this review's main outcomes. Data were checked for accuracy. Standard Cochrane review methods were used throughout. MAIN RESULTS: We identified two studies (involving a total of 73 women) comparing cervical cerclage alone to a different comparator. We also identified three ongoing studies (one investigating vaginal progesterone after cerclage, and two investigating cerclage plus pessary). One study (20 women), conducted in the UK, comparing cervical cerclage in combination with a tocolytic (salbutamol) with cervical cerclage alone in women with singleton pregnancy did not provide any useable data for this review. The other study (involving 53 women, with data from 50 women) took place in the USA and compared cervical cerclage in combination with a tocolytic (indomethacin) and antibiotics (cefazolin or clindamycin) versus cervical cerclage alone - this study did provide useable data for this review (and the study authors also provided additional data on request) but meta-analyses were not possible. This study was generally at a low risk of bias, apart from issues relating to blinding. We downgraded the certainty of evidence for serious risk of bias and imprecision (few participants, few events and wide 95% confidence intervals). Cervical cerclage in combination with an antibiotic and tocolytic versus cervical cerclage alone (one study, 50 women/babies) We are unclear about the effect of cervical cerclage in combination with antibiotics and a tocolytic compared with cervical cerclage alone on the risk of serious neonatal morbidity (RR 0.62, 95% CI 0.31 to 1.24; very low-certainty evidence); perinatal loss (data for miscarriage and stillbirth only - data not available for neonatal death) (RR 0.46, 95% CI 0.13 to 1.64; very low-certainty evidence) or preterm birth < 34 completed weeks of pregnancy (RR 0.78, 95% CI 0.44 to 1.40; very low-certainty evidence). There were no stillbirths (intrauterine death at 24 or more weeks). The trial authors did not report on the numbers of babies discharged home healthy (without obvious pathology) or on the risk of neonatal death. AUTHORS' CONCLUSIONS: Currently, there is insufficient evidence to evaluate the effect of combining a tocolytic (indomethacin) and antibiotics (cefazolin/clindamycin) with cervical cerclage compared with cervical cerclage alone for preventing spontaneous PTB in women with singleton pregnancies. Future studies should recruit sufficient numbers of women to provide meaningful results and should measure neonatal death and numbers of babies discharged home healthy, as well as other important outcomes listed in this review. We did not identify any studies looking at other treatments in combination with cervical cerclage. Future research needs to focus on the role of other interventions such as vaginal support pessary, reinforcing or second cervical cerclage placement, 17-alpha-hydroxyprogesterone caproate or dydrogesterone or vaginal micronised progesterone, omega-3 long chain polyunsaturated fatty acid supplementation and bed rest.

Pumpkin Oil-Based Nanostructured Lipid Carrier System for Antiulcer Effect in NSAID-Induced Gastric Ulcer Model in Rats.

BACKGROUND: Peptic ulcer disease, a painful lesion of the gastric mucosa, is considered one of the most common gastrointestinal disorders. This study aims to investigate the formulation of pumpkin seed oil (PSO)-based nanostructured lipid carriers (NLCs) to utilize PSO as the liquid lipid component of NLCs and to achieve oil dispersion in the nano-range in the stomach. METHODS: Box-Behnken design was utilized to deduce the optimum formula with minimum particle size. The optimized PSO-NLCs formula was investigated for gastric ulcer protective effects in Wistar rats by evaluating ulcer index and determination of gastric mucosa oxidative stress parameters. RESULTS: PSO was successfully incorporated as the liquid lipid (LL) component of NLCs. The prepared optimum PSO-NLCs formula showed a size of 64.3 nm. Pretreatment of animals using the optimized PSO-NLCs formula showed significantly (p< 0.001) lower ulcer index compared to indomethacin alone group and significantly (p<0.05) less mucosal lesions compared to the raw oil. CONCLUSION: These results indicated great potential for future application of optimized PSO-NLCs formula for antiulcer effect in non-steroidal anti-inflammatory drug (NSAID)-induced gastric ulcer.

Ibuprofen for the treatment of patent ductus arteriosus in preterm or low birth weight (or both) infants.

BACKGROUND: Indomethacin is used as standard therapy to close a patent ductus arteriosus (PDA) but is associated with reduced blood flow to several organs. Ibuprofen, another cyclo-oxygenase inhibitor, may be as effective as indomethacin with fewer adverse effects. OBJECTIVES: To determine the effectiveness and safety of ibuprofen compared with indomethacin, other cyclo-oxygenase inhibitor(s), placebo, or no intervention for closing a patent ductus arteriosus in preterm, low-birth-weight, or preterm and low-birth-weight infants. SEARCH METHODS: We used the standard search strategy of Cochrane Neonatal to search the Cochrane Central Register of Controlled Trials (CENTRAL 2017, Issue 10), MEDLINE via PubMed (1966 to 30 November 2017), Embase (1980 to 30 November 2017), and CINAHL (1982 to 30 November 2017). We searched clinical trials databases, conference proceedings, and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials of ibuprofen for the treatment of a PDA in preterm, low birth weight, or both preterm and low-birth-weight newborn infants. DATA COLLECTION AND ANALYSIS: Data collection and analysis conformed to the methods of the Cochrane Neonatal Review Group. We used the GRADE approach to assess the quality of evidence. MAIN RESULTS: We included 39 studies enrolling 2843 infants. Ibuprofen (IV) versus placebo: IV Ibuprofen (3 doses) reduced the failure to close a PDA compared with placebo (typical relative risk (RR); 0.62 (95% CI 0.44 to 0.86); typical risk difference (RD); -0.18 (95% CI -0.30 to -0.06); NNTB 6 (95% CI 3 to 17); I2 = 65% for RR and I2 = 0% for RD; 2 studies, 206 infants; moderate-quality the evidence). One study reported decreased failure to close a PDA after single or three doses of oral ibuprofen compared with placebo (64 infants; RR 0.26, 95% CI 0.11 to 0.62; RD -0.44, 95% CI -0.65 to -0.23; NNTB 2, 95% CI 2 to 4; I2 test not applicable). Ibuprofen (IV or oral) compared with indomethacin (IV or oral): Twenty-four studies (1590 infants) comparing ibuprofen (IV or oral) with indomethacin (IV or oral) found no significant differences in failure rates for PDA closure (typical RR 1.07, 95% CI 0.92 to 1.24; typical RD 0.02, 95% CI -0.02 to 0.06; I2 = 0% for both RR and RD; moderate-quality evidence). A reduction in NEC (necrotising enterocolitis) was noted in the ibuprofen (IV or oral) group (18 studies, 1292 infants; typical RR 0.68, 95% CI 0.49 to 0.94; typical RD -0.04, 95% CI -0.07 to -0.01; NNTB 25, 95% CI 14 to 100; I2 = 0% for both RR and RD; moderate-quality evidence). There was a statistically significant reduction in the proportion of infants with oliguria in the ibuprofen group (6 studies, 576 infants; typical RR 0.28, 95% CI 0.14 to 0.54; typical RD -0.09, 95% CI -0.14 to -0.05; NNTB 11, 95% CI 7 to 20; I2 = 24% for RR and I2 = 69% for RD; moderate-quality evidence). The serum/plasma creatinine levels 72 hours after initiation of treatment were statistically significantly lower in the ibuprofen group (11 studies, 918 infants; MD -8.12 µmol/L, 95% CI -10.81 to -5.43). For this comparison, there was high between-study heterogeneity (I2 = 83%) and low-quality evidence. Ibuprofen (oral) compared with indomethacin (IV or oral): Eight studies (272 infants) reported on failure rates for PDA closure in a subgroup of the above studies comparing oral ibuprofen with indomethacin (IV or oral). There was no significant difference between the groups (typical RR 0.96, 95% CI 0.73 to 1.27; typical RD -0.01, 95% CI -0.12 to 0.09; I2 = 0% for both RR and RD). The risk of NEC was reduced with oral ibuprofen compared with indomethacin (IV or oral) (7 studies, 249 infants; typical RR 0.41, 95% CI 0.23 to 0.73; typical RD -0.13, 95% CI -0.22 to -0.05; NNTB 8, 95% CI 5 to 20; I2 = 0% for both RR and RD). There was low-quality evidence for these two outcomes. There was a decreased risk of failure to close a PDA with oral ibuprofen compared with IV ibuprofen (5 studies, 406 infants; typical RR 0.38, 95% CI 0.26 to 0.56; typical RD -0.22, 95% CI -0.31 to -0.14; NNTB 5, 95% CI 3 to 7; moderate-quality evidence). There was a decreased risk of failure to close a PDA with high-dose versus standard-dose of IV ibuprofen (3 studies 190 infants; typical RR 0.37, 95% CI 0.22 to 0.61; typical RD - 0.26, 95% CI -0.38 to -0.15; NNTB 4, 95% CI 3 to 7); I2 = 4% for RR and 0% for RD); moderate-quality evidence). Early versus expectant administration of IV ibuprofen, echocardiographically-guided IV ibuprofen treatment versus standard IV ibuprofen treatment, continuous infusion of ibuprofen versus intermittent boluses of ibuprofen, and rectal ibuprofen versus oral ibuprofen were studied in too few trials to allow for precise estimates of any clinical outcomes. AUTHORS' CONCLUSIONS: Ibuprofen is as effective as indomethacin in closing a PDA. Ibuprofen reduces the risk of NEC and transient renal insufficiency. Therefore, of these two drugs, ibuprofen appears to be the drug of choice. The effectiveness of ibuprofen versus paracetamol is assessed in a separate review. Oro-gastric administration of ibuprofen appears as effective as IV administration. To make further recommendations, studies are needed to assess the effectiveness of high-dose versus standard-dose ibuprofen, early versus expectant administration of ibuprofen, echocardiographically-guided versus standard IV ibuprofen, and continuous infusion versus intermittent boluses of ibuprofen. Studies are lacking evaluating the effect of ibuprofen on longer-term outcomes in infants with PDA.

A comparative study on the efficacy of nifedipine and indomethacin for prevention of preterm birth as monotherapy and combination therapy: a randomized clinical trial.

Introduction: Preterm delivery is an important issue in obstetrics, which is the most common cause of neonatal mortality and morbidity. Therefore, finding a way to prevent it is always under serious concern.Objective: The study aimed to compare the efficacy of two tocolytic agents, nifedipine and indomethacin, for inhibiting preterm uterine contractions as monotherapy and combination therapy.Materials and methods: A double-blind randomized clinical trial was performed on pregnant women with gestational age of 26-34 weeks of pregnancy who referred to hospital for preterm labor. They were randomly assigned to three groups. Indomethacin plus placebo, nifedipine plus placebo, and a combination of indomethacin and nifedipine were administered to the three groups. Inhibiting contractions for 2 hours and prevention of delivery for 48 hours and 7 days were evaluated. Also, duration of pregnancy, the number of preterm births, and the interval between entering the study and delivery were compared between three groups.Results: One hundred fifty women were eligible for the study. Two women in the nifedipine group and one woman in the combined group were excluded from the study because of hypotension. The women of the three groups did not have significant difference according to age, BMI, gravidity, parity, Bishop score, gestational age, and the number of contractions at entering the study. Thirty-six women (72%) in the indomethacin group, 36 women (72%) in the nifedipine group, and 41 women (89.4%) in the combination group had stopped contractions within the first 2 hours of intervention (p = .002). Inhibiting contractions for 48 hours (p = .003), inhibiting contractions for 7 days (p = .021), gestational age at birth (p = .001), number of pregnancies more than 37 weeks (p = .007), and neonatal weight (p = .020) were significantly more in the combination group.Conclusion: Combination therapy with nifedipine and indomethacin was more effective than monotherapy with either of these two medications for inhibiting preterm labor, delaying delivery, and prolongation of the duration of pregnancy.

PPARα ligand, AVE8134, and cyclooxygenase inhibitor therapy synergistically suppress lung cancer growth and metastasis.

BACKGROUND: Lung cancer (LC) is one of the leading causes of death worldwide, which highlights the urgent need for better therapies. Peroxisome proliferator-activated nuclear receptor alpha (PPARα), known as a key nuclear transcription factor involved in glucose and lipid metabolism, has been also implicated in endothelial proliferation and angiogenesis. However, the effects and potential mechanisms of the novel PPARα ligand, AVE8134, on LC growth and progression remain unclear. METHODS: A subcutaneous tumour was established in mice by injecting TC-1 lung tumour cells (~ 1 × 106 cells) into their shaved left flank. These mice were treated with three different PPARα ligands: AVE8134 (0.025% in drinking water), Wyeth-14,643 (0.025%), or Bezafibrate (0.3%). Tumour sizes and metastasis between treated and untreated mice were then compared by morphology and histology, and the metabolites of arachidonic acid (AA) were detected by liquid chromatography-tandem mass spectrometry (LC-MS/MS). Inhibition of either Cyp2c44 expression by genetic disruption or cyclooxygenase (COX) activity by indomethacin was used to test the mechanisms by which AVE8134 affects tumour growth. RESULTS: The pharmacodynamics effects of AVE8134, Wyeth-14,643, and Bezafibrate on lipids control were similar. However, their effects on tumour suppression were different. Eicosanoid profile analysis showed that all PPARα ligands reduced the production of AA-derived epoxyeicosatrienoic acids (EETs) and increased the hydroxyl product, 11-hydroxyeicosatetraenoic acids (11-HETE). Moreover, increased 11-HETE promoted endothelial proliferation, angiogenesis, and subsequent tumour deterioration in a dose-dependent manner possibly via activating the AKT/extracellular signal-regulated kinase (ERK) pathway. The increased 11-HETE partly neutralized the benefits provided by the Cyp2c44-EETs system inhibited by PPARα ligands in tumour-bearing mice. AVE8134 treatment worsened the tumour phenotype in Cyp2c44 knockout mice, indicating that AVE8134 has contradictory effects on tumour growth. The COX inhibitor indomethacin strengthened the inhibitory actions of AVE8134 on tumour growth and metastasis by inhibiting the 11-HETE production in vivo and in vitro. CONCLUSION: In this study, we found that the degrees of inhibition on LC growth and metastasis by PPARα ligands depended on their bidirectional regulation on EETs and 11-HETE. Considering their safety and efficacy, the novel PPARα ligand, AVE8134, is a potentially ideal anti-angiogenesis drug for cancer treatment when jointly applied with the COX inhibitor indomethacin.

Identification of a novel X-linked arginine-vasopressin receptor 2 mutation in nephrogenic diabetes insipidus: Case report and pedigree analysis.

INTRODUCTION: The clinical and genetic characteristics of nephrogenic diabetes insipidus (NDI) were described via assessing 2 cases of NDI patients from a Chinese family. PATIENT CONCERNS: Two patients who manifest polyuria and polydipsia were admitted to hospital for definite diagnosis. DIAGNOSIS: Water deprivation-vasopressin tests showed that the patients may possess renal-origin diabetes insipidus. All the levels of thyroid-stimulating hormone, luteinizing hormone, follicle stimulation hormone, adrenocorticotropic hormone, prolactin, and growth hormone in both patients were normal. These results were certified that both patients possess a nephropathy-type diabetes insipidus. B-mode ultrasonography and urinalysis test demonstrated that the patient's diabetes insipidus is unlikely to originate from renal organic disease. Remarkably, by nucleotide sequencing, we found a novel mutation c.414_418del in arginine-vasopressin receptor 2 (AVPR2) was related to the disease of NDI. INTERVENTIONS: Two patients were treated with oral hydrochlorothiazide and indomethacin. In addition, low salt diet and potassium supplementation throughout the patients' treatment. OUTCOMES: The clinical symptoms of 2 patients were significantly reduced after targeted therapy. CONCLUSION: A mutation in AVPR2 was discovered to be associated with NID. It provides a new target for molecular diagnosis of NDI, enabling families to undergo genetic counseling and obtain prenatal diagnoses.

Celecoxib, ibuprofen, and indomethacin alleviate depression-like behavior induced by interferon-alfa in mice.

Background Interferon-α (IFNα) therapy causes psychiatric side effects, including depression that may result in poor compliance of therapy. It is important to find alternative therapies for the prevention of IFNα induced depression. Non-steroidal anti-inflammatory drugs (NSAIDs) have been useful in depressive disorder. Therefore the effects of celecoxib, ibuprofen, and indomethacin were evaluated following IFNα-induced depression in mice. Methods Male albino mice weighing 26 ± 2 g were used. Depression was induced by IFNα (16 × 105 IU/kg, SC) for six consecutive days. Animals were first subject to the locomotor test, then the splash test and finally the forced swimming test (FST) on the 7th day. The NSAIDs were administered (IP) either one single dose before the test, or simultaneously with IFNα. Results locomotor activity was only impaired by ibuprofen high dose (75 mg/kg), thus it was not further evaluated. Following IFNα therapy depression-like behaviors were observed; significant changes during the splash test (grooming time 24 ± 7 sec vs. control 63 ± 7 sec), the FST (immobility time 166  ± 15 sec vs. control 128  ± 6 sec), and sucrose preference reduced to 64 ± 0.8%. The NSAIDs noticeably reduced the immobility time in FST, while grooming time was increased. Celecoxib and indomethacin single doses were effective while ibuprofen showed better antidepressant effects when it was administered along with IFNα. Conclusions The NSAIDs were able to prevent IFNα induced depression in mice. NSAIDs administration with IFNα does not interfere with clinical benefit effects of IFNα and they could also be useful to prevent IFNα psychiatric side effects, thus further clinical trials are suggested.

The Use of Indomethacin with Complete Amniotic Fluid Replacement and Classic Hysterotomy for the Reduction of Perinatal Complications of Intrauterine Myelomeningocele Repair.

OBJECTIVE: This study presented outcomes of classical hysterotomy with modified antiprostaglandin therapy for intrauterine repair of foetal myelomeningocele (fMMC) performed in a single perinatal centre. STUDY DESIGN: Forty-nine pregnant women diagnosed with fMMC underwent classic hysterotomy with anti-prostaglandin management, complete amniotic fluid replacement and high dose indomethacin application. RESULTS: The average gestational age (GA) at delivery was 34.4 ± 3.4 weeks, with no births before 30 weeks GA. There were 2 foetal deaths. Complete reversal of hindbrain herniation (HH), assessed in magnetic resonance imaging at 30-31 weeks GA was found in 72% of foetuses (mostly with HH grade I prior to fMMC repair). Our protocol resulted in rare use of magnesium sulphate (6%), low incidence of chorioamniotic membrane separation - chorioamniotic membrane separation (6%), preterm premature rupture of membranes - preterm premature rupture of membranes (pPROM; 15%) and preterm labour - preterm labour (PTL; 17%). The postoperative wound continuity of the uterus was usually stable (in 72% of patients), with low frequency of scar thinning (23%). CONCLUSION: Our protocol results in rare use of tocolytics, and the low occurrences of CMS, pPROM and PTL in relation to other study cohorts: Management of Myelomeningocele Study, Children's Hospital of Philadelphia, and Vanderbilt University Medical Centre.

Effect of nonsteroidal anti-inflammatory drugs in children with Bartter syndrome.

BACKGROUND: Bartter syndrome (BS) is a salt-wasting tubulopathy with induced expression of cyclooxygenase-2 in the macula densa, leading to increased prostaglandin production and hyperreninemia. Nonsteroidal anti-inflammatory drugs (NSAIDs) are currently used in BS; however, there is limited information on the impact of NSAIDs at treatment initiation or the potential utility of plasma renin level to guide therapy in patients with BS. METHODS: We included 19 patients with BS treated with NSAIDs between 1994 and 2016. We assessed serum levels of renin, aldosterone, electrolytes, calcium, phosphorus, vitamin D, and intact parathyroid hormone (iPTH) before and after treatment initiation. We also recorded modifications in sodium and potassium supplements and changes in urine calcium. RESULTS: Median age at diagnosis was 0.9 months [IQR 0-6.9]. Seven patients had BS types 1 or 2, 12 had BS type 3 and two had no mutation identified. There was a trend towards a decrease in sodium chloride supplementation after initiation of NSAIDs. When defining response to treatment based on the normalization of plasma renin level, responders had a greater reduction in their electrolytes supplementation. NSAIDs treatment was associated with a reduction in urine calcium. Before treatment, half of the patients had elevated iPTH, but iPTH normalized following initiation of NSAIDs in all but one patient. CONCLUSIONS: This study confirms that NSAIDs reduce urine wasting of sodium and calcium in patients with BS. Monitoring serum renin levels may be useful to identify the lowest effective dose of NSAIDs that optimizes reduction of urine electrolyte losses.
