Background: Anovulatory dysfunction is a commonly encountered problem which is responsible for about 40% of female infertility. One of the leading causes of female infertility is polycystic ovarian syndrome (PCOS). Clomiphene citrate has been the drug of choice in treating women with anovulatory infertility. However, in recent years, letrozole, an aromatase inhibitor, has emerged as alternative ovulation induction agent. Aim of this study was to compare efficacy of clomiphene citrate and letrozole as first line therapy for ovulation induction in polycystic ovarian syndrome.Methods: This study was a hospital based prospective comparative study done in MVJ MC and RH involving 100 females suffering from infertility due to anovulation. They were divided into 2 groups of 50 each. One group was given clomiphene citrate 50 mg while another group was given letrozole 2.5 mg from day 3 to day 7 of menstrual cycle. Ultrasonographic follicular monitoring was done and injection beta HCG 5000 IU was given once follicle reached optimum size (≥18 mm) and endometrial thickness was adequate (≥7 mm). Patients were advised for timed intercourse after 24-36 hours of HCG administration. Ovulation was detected by sonographic findings of follicular rupture done after 48 hours. Primary outcomes measured were number of growing follicles (≥18 mm), endometrial thickness, ovulation rate and pregnancy rate.Results: In our study there was significant difference in the outcomes of ovulation induction between letrozole group and clomiphene group.  Women who received letrozole showed improved endometrial growth (8.44 mm versus 7.86 mm), ovulation rate (72% versus 56%) and pregnancy rate (22.2% versus 14.3%) than those who received clomiphene. However, variation in follicular growth was negligible between the two groups (1.28 versus 1.36).Conclusions: Letrozole is a superior alternative to clomiphene citrate for ovulation induction in cases of PCOS with anovulatory menstrual cycle, and can be considered as first-line therapy for ovulation induction in such women.

Background: Polycystic ovary syndrome is the commonest endocrinopathy resulting in anovulatory infertile young women. Clomifene citrate (clomiphene) is a long-standing standard drug for ovulation induction, and is still considered as first line option in PCOS women. However, clomiphene has certain disadvantage letrozole an aromatase inhibitor acts by reducing estrogen production and has no adverse effects on endometrium and cervical mucous. Indian PCOS women have high prevalence of insulin resistance and thus are likely to have high clomiphene resistance. So letrozole could prove to be a good alternative for ovulation induction in such women.Methods: This was a prospective randomized, parallel, comparative clinical trial of two ovulation induction drugs letrozole 5 mg versus clomiphene citrate 100 mg as first-line ovulation induction drug in infertile polycystic ovarian syndrome women. The target population of the study was one hundred infertile women with PCO (taking at least 2 Rotterdam’s parameters). 50 women were allocated to clomifene citrate and 50 were allocated to Letrozole for ovulation induction. Parameters like age, duration of infertility, B MI, ovulation rate, number of follicles, pregnancy rate, endometrial thickness were noted and analyzed.Results: In letrozole group, the ovulation rate, mono-follicular development, mean endometrial thickness and pregnancy rate was better in comparison to clomifene citrate group.Conclusions: The result of this study suggests that letrozole may replace clomiphene as the first line drug for ovulation induction in infertile PCOS women.

The study was designed to compare the effectiveness of Letrozole and clomiphen citrate in the treatment of anovulatorv infertility. Thirty patients were selected randomly who had anovulatorv infertility. In letrozole group, fifteen patients got 5-7.5 mg of letrozole orally and in clomiphen citrate group, 100-150 mg of clomiphen citrate was given orally for maximum of six cycles and in both the groups the drugs were started from day 3 -7 of the menstrual cycle. There were no significant differences between the age, duration and type of fertility. But statistically significant increase of follicular development in letrozole group (ñ=0.020). Mean endometrial thickness was 8.33±1.54 and 5.36±1.84 respectively in letrozole and in clomiphen citrate group (ñ =0.048). There was no significant difference in ovulation in both the groups but pregnancy was more (33.3%) with the letrozole group. Letrozole is an effective agent for ovulation induction. It can be used as an alternative to CC as a first-line of treatment for ovulation induction. DOI: 10.3329/bjpp.v25i1.5739Bangladesh J Physiol Pharmacol 2009; 25(1&2) : 10-12

Background: The present study was design to compare letrozole (5 mg) and clomiphene citrate (100 mg) as first line ovulation induction drug in infertile anovulatory polycystic ovarian syndrome (PCOS) women.Methods: This prospective randomized clinical trial included 60 cases of PCOS with anovulatory infertility. The first group comprised of 30 patients who received 5 mg letrozole daily and the second group received 100 mg clomiphene citrate daily for 5 days starting on day 2-5 of menses. Both the groups were followed by ultrasound for follicle monitoring, ovulation and endometrial thickness. When dominant follicle reaches a diameter of more than or equal to 18mm and endometrial thickness ≥7.5 mm, human chorionic gonadotrophin (hCG) 5,000 IU was given intramuscularly and timed intercourse was advised. Main outcome measures were occurrence of ovulation, endometrial thickness and pregnancy rates.Results: The mean age, body mass index, and number of cases of primary and secondary infertility in both the groups showed no statistically significant difference. Multi-follicular development during induction was statistically significantly greater in the clomiphene group (1.27±1.11 versus 2.03±1.65; p=0.041). Ovulation occurred in 24 subjects (80%) in letrozole group and 18 subjects (60%) in the clomiphene group, with a statistically significant difference between the two groups (p=0.024). Pregnancy occurred in 16 subjects (53.33%) in letrozole group and 7 subjects (23.33%) in clomiphene group, which shows statistically significant difference between the two groups (p=0.048).Conclusions: Though number of developing follicles was found statistically significant with clomiphene citrate but ovulation rate and pregnancy rate were higher with letrozole group. Therefore, letrozole is a safe and better alternative for ovulation induction in patients of anovulatory PCOS, and it may be considered as a first line treatment for ovulation induction in these patients.

Abstract Background Background: Antibiotic resistance is a major public health concern. A modifiable intervention is outpatient antibiotic stewardship. The goal of this study was to review the electronic health records (EHR) of children diagnosed with community acquired pneumonia (CAP) to compare patients who received non-guideline concordant therapy with those prescribed recommended therapy. Methods Methods: This was a retrospective chart review of 300 children (6 months to 6 years old) with an outpatient diagnosis of CAP between July 2017 and June 2019. 45 Children’s Hospital of Pittsburgh (CHP) and UPMC Children’s Community Pediatrics (CCP) practices were included. CHP practices are academic-based with trainees involved in visits, while CCP practices do not include trainees. First-line recommended therapy was defined as amoxicillin, second-line therapy as azithromycin or amoxicillin-clavulanate, and all other prescriptions were defined as other. Patients prescribed first-line therapy were compared to patients with second-line therapy or other. If first-line therapy was not prescribed, the EHR was manually reviewed for justification. If drug allergy was listed, the medication allergy and type of reaction were recorded. Results Results: In this study the minority of children (43%) were prescribed first-line therapy. This group was younger (57 vs. 63 months of age), more likely to be Non-white (80%), and seen at the CHP locations than those prescribed non-guideline concordant therapy. The average symptom duration was shorter, heart rate and respiratory rate were higher and the presence of fever was more common in the first-line therapy group. Justification for non-guideline therapy was most often reported as to provide coverage for atypical organisms. The most common drug allergy recorded was amoxicillin, and urticaria with unknown timing was the most common type of reaction. Demographics Comparison Results Justification for Second-line / Other Therapy and Drug Allergy Results Conclusion This project observed a high proportion of children being prescribed non-guideline concordant therapy for a diagnosis of CAP. Age, race, practice location, and severity of illness measures showed a statistically significant difference between groups. This study highlights the importance of education which reviews the current guidelines and the most likely pathogens for children with CAP. Disclosures All Authors: No reported disclosures

Abstract Background: Sunitinib and pazopanib are orally-administered tyrosine kinase receptor inhibitors (TKIs) approved as first-line therapy for the treatment of metastatic renal cell carcinoma (mRCC). The IMDC criteria are a predictive prognostic model for patients with mRCC when stratified into three prognosis groups: favourable, intermediate and poor. We retrospectively compared the efficacy and safety of sunitinib and pazopanib as first-line therapy for patients with mRCC in our single institution database. Methods: Retrospective analysis was done to compare progression-free survival (PFS) and side effects of sunitinib and pazopanib as first-line therapy in patients with mRCC. Patients were stratified into prognosis groups according to IMDC criteria. Disease assessment was performed on measurable aspects of disease based on computed tomography or magnetic resonance imaging reports. Survival analysis was performed using the Kaplan-Meier method and Cox regression, with disease progression as the endpoint.Results: Data was obtained from 228 patients with mRCC who were treated with either pazopanib (n=57) or sunitinib (n=171). No significant difference in PFS was found between sunitinib and pazopanib (HR for disease progression or all-cause death, 1.10; 95%CI: 0.76-1.57, p=0.62). Median PFS time for patients receiving sunitinib was 9.4 months and for pazopanib, 8.5 months. Median PFS for patients with intermediate-risk disease was similar between groups (9.4 months vs. 9.2 months, respectively, p=0.93). However, patients treated with sunitinib experienced a greater number of side effects compared to pazopanib. Conclusions: Sunitinib and pazopanib are similarly efficacious as first-line therapy for mRCC. However, adverse events are lower with pazopanib.

Objectives: The objective is to evaluate the clinical outcome of using letrozole alone or with gonadotropin as first-line ovulation induction in anovulatory infertile polycystic ovary women. Methods: A prospective single-arm study. 80 infertile polycystic ovarian syndrome (PCOS) women had been recruited between January and October 2017. Letrozole on day 2–3 of the cycle was given. The women are sorted into two groups according to the size of the dominant follicle on day 7 or 8, Group A (letrozole only group) and Group B (letrozole plus gonadotropin).Results: In our study, the overall pregnancy rate was (67.5%) and ovulation rate was 91.3%. The ovulation rate was significantly higher in Subgroup A than B (97.9% vs. 81.3%). Pregnancy rate was higher in Subgroup A (72.9% vs. 59.4%), but it was statistically not significant. The number of follicles was significantly higher in Subgroup B. Endometrial thickness, miscarriages, ovarian hyperstimulation syndrome, and multiple pregnancies were not statistically significant. Lower cycle number independently and significantly predict clinical pregnancy, while body mass index has a modest effect.Conclusions: Letrozole alone or in combination with gonadotropin as a first-line treatment in PCOS may be reasonable since this approach may improve the success rate and minimize the overall costs and risks.

Background: To compare two protocols comprising of FSH/CC/HMG and CC/HMG for ovulation induction and IUI in women with infertility.Methods: 60 women with unexplained infertility were randomized using sequentially numbered opaque envelope method. Group A received inj FSH 150 units on day 2 of menstrual cycle and clomiphene citrate 100 mg from day 3-7, followed by injection HMG 150 units on day 9 of menstrual cycle. Group B received clomiphene citrate 100 mg from day 3-7, and HMG 150 units on day 7 and 9 of the menstrual cycle.  Ovulation triggered with hCG 5000 units when dominant follicle was 18mm. Single IUI was done 36-42 hours afterwards.Results: Pregnancy occurred in 3 out of 30 women in 116 cycles Group A (with FSH) with a pregnancy rate of 10 percent, and 2.8% per cycle. In group B (without FSH) pregnancy occurred in 3 out of 30 women in 117 cycles with pregnancy rate of 10 percent, and 2.6% per cycle. The number of follicles per cycle was 1.36 and follicle size was 18.57 mm in group A. While in Group B numbers of follicles per cycle were 1.22, with average size of 18.9mm. Mean endometrial thickness was 7.7mm in Group A and 6.37 in Group B (p=.01, significant). Mild OHSS was observed in one woman in Group B. No other side effects were observed in both the groups.Conclusions: The controlled ovarian stimulation regimes used in this study are equally effective, easy to administer, require less intensive monitoring and fewer medications, with little risk of OHSS and multiple gestation.

Objective To compare the effects of letrozole (5 mg) and clomiphene citrate (100 mg) for ovulation induction in women with polycystic ovary syndrome (PCOS). Design Prospective randomized trial. Setting University teaching hospital and private practice setting. Patients The study comprised a total of 438 infertile women (1063 cycles) with PCOS. Intervention Patients were randomized to treatment with 5 mg of letrozole daily (218 patients, 545 cycles) or 100 mg of clomiphene citrate daily (220 patients, 518 cycles) for 5 days starting on day 3 of menses. Timed intercourse was advised 24 to 36 hours after hCG injection. Main Outcome Measure Number of follicles, serum estradiol, serum progesterone, endometrial thickness, and pregnancy and miscarriage rates. Results The mean age, parity, and duration of infertility in both groups were similar. The total number of follicles was statistically significantly greater in the clomiphene citrate group (6.8 _ 0.3 vs 4.4 _ 0.4). Endometrial thickness at the time of hCG administration was statistically significantly greater in the CC group (9.2 _ 0.7 mm vs 8.1 _ 0.2 mm). The duration to reach a dominant follicle was statistically significantly longer in the letrozole group (12.1_1.3 vs 8.8_2.9 days). Ovulation occurred in 365 out of 540 cycles (67.5%) in letrozole group and 371 out of 523 cycles (70.9%) without a statistically significant difference. Levels of serum estradiol and progesterone were statistically significantly higher in the clomiphene citrate group. The pregnancy rate per cycle was 15.1% in the letrozole group and 17.9% in the clomiphene citrate group without statistically difference between the groups. Conclusion The results of this study did not show any advantage to the use of letrozole over clomiphene citrate as a first-line treatment for induction of ovulation in women with PCOS (Fertil Steril_2009;92:849-52. _2009 by American Society for Reproductive Medicine).

7572 Background: The GCLLSG evaluated the efficacy of fludarabine (F) versus (vs.) chlorambucil (Clb) in first line therapy of older patients with advanced CLL. HRQOL was evluated by using the EORTC C30 questionnaire. Methods: Pts were randomized to receive 6 courses of F (25 mg/m²/day (d) IV for 5d; 92 pts) or 12 months (mo) of Clb (0.4–0.8 mg/kg/d PO, every 15d; 99 pts). All pts were previously untreated, aged between 65 and 79 years and in advanced stage Binet C or symptomatic Binet B or A. Primary endpoints were overall survival (OS) and progression free survival (PFS), secondary endpoint was HRQOL. The EORTC C30 questionnaire (version 2.0) was sent to all patients at baseline and after 6, 12 and 24 mo. Scores (0–100) for 15 different measures (1 global HRQOL, 5 functional, 3 symptom and 6 single item scales) were evaluated at each time point. Results: F induced significantly higher response rates and prolonged the PFS, while no significant difference in OS was observed. At baseline 130 of 191 pts (68%) completed the questionnaires followed by more than 80% at mo 6 to 24. Compliance rates were similar in both treatment arms. Between pts completing questionnaires or not no statistically significant differences in perfomance status, age, stage or response to treatment were observed. HRQOL differences in comparison to baseline values were significantly improved after F treatment in global HRQOL, role and social functioning after 12 months as shown by the table. Responders had a significantly better global HRQOL and social functioning as well. Except for an impaired physical functioning no differences in HRQOL were observed between different age groups (65–69, 70–74, 75–79). Conclusion: Elderly F treated patients with CLL showed improvement inglobal HRQOL. Elderly age groups had a similar HRQOL as younger age groups. [Table: see text] [Table: see text]
