Introduction: H. pylori eradication reduces the risk of gastric malignancies and peptic ulcer disease. First-line therapies include 14-day PAC (proton pump inhibitor [PPI], amoxicillin, clarithromycin) and PBMT (PPI, bismuth, metronidazole, tetracycline). Second-line therapies include 14-day PBMT and PAL (PPI, amoxicillin, levofloxacin). This clinical audit examined current treatment outcomes in Singapore. Methods: Clinical data of H. pylori-positive patients who underwent empirical first- and second-line eradication therapies from 1 January 2017 to 31 December 2018 were reviewed. Treatment success was determined by 13C urea breath test performed at least 4 weeks after treatment and 2 weeks off PPI. Results: A total of 963 patients (862 PAC, 36 PMC [PPI, metronidazole, clarithromycin], 18 PBMT, 13 PBAC [PAC with bismuth], 34 others) and 98 patients (62 PMBT, 15 PAL, 21 others) received first- and second-line therapies respectively. A 14-day treatment duration was appropriately prescribed for first- and second-line therapies in 65.2% and 82.7% of patients, respectively. First-line treatment success rates were noted for PAC (seven-day: 76.9%, ten-day: 88.3%, 14-day: 92.0%), PMC (seven-day: 0, ten-day: 75.0%, 14-day: 69.8%), PBMT (ten-day: 100%, 14-day: 87.5%) and PBAC (14-day: 100%). 14-day treatment was superior to seven-day treatment (90.8% vs. 71.4%; p = 0.028). PAC was superior to PMC (p < 0.001) but similar to PBMT (p = 0.518) and PBAC (p = 0.288) in 14-day therapies. 14-day second-line PAL and PBMT had similar efficacy (90.9% vs. 82.4%; p = 0.674). Conclusion: First-line empirical treatment using PAC, PBMT and PBAC for 14 days had similar efficacy. Success rates for second-line PBMT and PAL were similar.

OBJECTIVE: To assessHelicobacter pylorieradication after one week dual ranitidine bismuth citrate-clarithromycin (RBC-C) or triple omeprazole, clarithromycin and amoxicillin (OCA) therapy.METHODS: In this multicentre Canadian trial,H pylori-positive patients with functional dyspepsia or inactive peptic ulcer disease were randomized to open-label treatment with RBC-C (ranitidine bismuth citrate 400 mg plus clarithromycin 500 mg) or OCA (omezaprole 20 mg, clarithromycin 500 mg and amoxicillin 1000 mg), given twice a day for seven days. Treatment allocation was randomly assigned.H pyloriinfection was confirmed by positive13C-urea breath test (13C-UBT).H pyloristatus was reassessed by UBT at least four and 12 weeks after treatment (negative: δ13CO2below 3.5 per mil). Intention-to-treat (ITT) eradication rates were determined for all patients with confirmedH pyloriinfection. Per protocol (PP) rate was determined for all patients treated with at least two evaluable follow-up visits.RESULTS: Three hundred five patients were included in the ITT and 222 in the PP analysis. The ITT eradication rates were 66% for RBC-C and 78% for OCA. The PP success rates were 84% for RBC-C and 96% for OCA. The difference for both ITT 12% (95% CI 2 to 22) and PP 12% (95% CI 4 to 19) were statistically significant, P=0.030 and P=0.007, respectively. Treatment was generally well tolerated.CONCLUSION: The eradication rate for the seven-day dual RBC-C regimen was lower than that for OCA.

Helicobacter pyloriinfection is the main cause of gastritis, gastroduodenal ulcer disease, and gastric cancer. After 30 years of experience inH. pyloritreatment, however, the ideal regimen to treat this infection has still to be found. Nowadays, apart from having to know well first-line eradication regimens, we must also be prepared to face treatment failures. In designing a treatment strategy, we should not only focus on the results of primary therapy alone but also on the final—overall—eradication rate. The choice of a “rescue” treatment depends on which treatment is used initially. If a first-line clarithromycin-based regimen was used, a second-line metronidazole-based treatment (quadruple therapy) may be used afterwards, and then a levofloxacin-based combination would be a third-line “rescue” option. Alternatively, it has recently been suggested that levofloxacin-based “rescue” therapy constitutes an encouraging 2nd-line strategy, representing an alternative to quadruple therapy in patients with previous PPI-clarithromycin-amoxicillin failure, with the advantage of efficacy, simplicity and safety. In this case, quadruple regimen may be reserved as a 3rd-line “rescue” option. Even after two consecutive failures, several studies have demonstrated thatH. pylorieradication can finally be achieved in almost all patients if several “rescue” therapies are consecutively given.

BACKGROUND: SuccessfulHelicobacter pylorieradication with the traditional seven-day course of proton pump inhibitor (PPI) triple therapy is declining. Prolonging therapy to either 10 or 14 days is associated with better eradications rates.OBJECTIVE: To compare the effectiveness of 14-day course of triple therapy versus a 10-day course in the treatment ofH pyloriin Canada.METHODS: Consecutive treatment-naive patients with clinical indications forH pylorieradication underwent either a 10-day course or a 14-day course of traditional PPI triple therapy depending on the date of the office visit (an odd date received the 10-day course, whereas an even date received the 14-day treatment).H pylorieradication was ascertained via urea breath test or gastric biopsies performed ≥4 weeks after completion of therapy. Analyses were by both intention to treat and per-protocol.RESULTS: A total of 83 patients were included in the study (31 in the 10-day group and 52 in the 14-day group). In the intention-to-treat analysis, eradication rates were 82.7% (95% CI 70% to 92%) versus 45.2% (95% CI 27% to 64%), favouring the 14-day treatment (P<0.001). Similarly, in the per-protocol analysis, eradication rates were 91.5% (95% CI 80% to 98%) versus 63.6% (95% CI 41% to 83%), favouring the 14-day arm (P=0.01). Adverse events and compliance were not significantly different between the two groups.CONCLUSION: A 14-day course of standard PPI triple therapy was superior to a shorter-duration therapy and should be included as a first-line regimen forH pylorieradication in Canada. The 10-day course of treatment did not achieve an acceptable eradication rate and should no longer be used in this country.

SUMMARYThe incidence of tuberculosis (TB) in native ethnic minorities remains high in developed countries. Arabs, the major ethnic minority in Israel, comprise 21% of its population. This retrospective study compared TB incidence, demographic, clinical, laboratory, genotyping characteristics and treatment outcomes in all Israeli-born citizens diagnosed with TB between 1999 and 2011 by ethnicity, i.e. Israeli-born Arabs (IA) and Jews (IJ). A total of 831 Israeli-born TB patients were reported. Of those, there were 530 (64%) IJ and 301 (36%) IA, with an average annual TB rate of 1·1 and 1·6 cases/100 000 population, respectively, lower than the national average (7·0 cases/100 000 population). TB rates in IA and IJ declined and converged to 1 case/100 000 residents. IA TB patients were more likely to be older, have more pulmonary TB and have lower treatment success rates than IJ. Older age and HIV co-infection, but not ethnicity, were predictive of non-success in TB treatment. Ten mixed IA–IJ clades were detected by spoligotyping and three mixed IA–IJ clusters were identified by MIRU-VNTR typing. Only one IA–IJ couple recalled mutual contact. In conclusion, TB rate in IA was higher than in IJ, but declined and converged in both to 1 case/100 000. Treatment success was high in both groups, and was unrelated to ethnicity.

Abstract Background: Globally, tuberculosis (TB) is the leading cause of death from a single infectious agent. Adherence to TB therapy is an important factor in treatment outcomes, which is a critical indicator for evaluating TB treatment programs. This study assessed TB treatment outcomes using a fifteen-year record of tuberculosis patients who received treatment in Jos North and Mangu Local Government Areas of Plateau State, North-Central Nigeria. Methods: The retrospective facility based study was done in five TB treatment centers which account for more than half of data for tuberculosis patients in Plateau State. Data were collected from 10156 TB patient’s health records between 2001 and 2015. Treatment outcomes were categorized as successful (cured, treatment completed) or unsuccessful (non-adherent, treatment failure or death). A descriptive analysis was done to assess the factors associated with treatment outcomes. Relevant bivariable and multivariable logistic regression were done. All statistical analyses were performed on Stata version 11, College station, Texas, USA.Results: During the study period, 58.1% (5904/10156) of the TB patients who received treatment were males. The Mean age ±SD was 35.5 ±15.5 years. The overall treatment success rate was 67.4%; non-adherence/defaulting rate was 18.5%, with majority of patients defaulting at the end of intensive phase of treatment. The sputum conversion rate was 72.8% and mortality rate was 7.5%. A decrease in successful treatment outcomes rate from 83.8% in 2001 to 64.4% in 2015 was observed. After adjusting for sex, and TB category, being HIV positive was 2.8 times (95% CI: 1.11-6.83, p=0.028) more likely to be associated with treatment success than having an unknown status. Treatment after loss to follow-up, relapse and treatment failure were less likely associated with treatment success than newly diagnosed TB patients.Conclusion: With the decrease in treatment success rates, underlying reasons for medication non-adherence and treatment failure should be resolved through adherence counseling involving the patient and treatment supporters, with education on voluntary counseling and testing for HIV among TB patients.

SETTING: An urban TB diagnostic centre in Lusaka, Zambia.OBJECTIVE: To re-evaluate treatment outcomes of all bacteriologically confirmed TB patients registered in 2018.DESIGN: This was a retrospective cohort study on TB patients. Treatment outcomes of patients who were transferred out were retrieved.RESULTS: A total of 182 patients were registered, 26 of whom had missing documents; these were excluded from the study. Of the remaining 156 patients who were reviewed, 86 (55.1%) were correctly evaluated by the centre, 35 (22.4%) were incorrectly evaluated and 35 (22.4%) were ‘transferred out’ (not evaluated). As a result of this review, the number of evaluated patients increased from 86 (55.1%) to 150 (96.2%). The cure and treatment success rates rose from 43.6% and 44.2%, respectively, to 57.7% and 73.1%, respectively. Of note, 14 of the 35 patients who were initially declared ‘transferred out’ did not actually reach their treatment facilities and ended up being lost to follow-up.CONCLUSION: This study shows that it is possible to evaluate almost all TB patients. Re-evaluation of treatment outcomes of TB patients revealed the problems in the TB services that need to be improved in the future.

Background Globally, drug resistant tuberculosis (DR-TB) continues to be a public health threat. Nigeria, which accounts for a significant proportion of the global burden of rifampicin/multi-drug resistant-TB (RR/MDR-TB) had a funding gap of $168 million dollars for TB treatment in 2018. Since 2010, Nigeria has utilized five different models of care for RR/MDR-TB (Models A-E); Models A, B and C based on a standardized WHO-approved treatment regimen of 20–24 months, were phased out between 2015 and 2019 and replaced by Models D and E. Model D is a fully ambulatory model of 9–12 months during which a shorter treatment regimen including a second-line injectable agent is utilized. Model E is identical to Model D but has patients hospitalized for the first four months of care while Model F which is to be introduced in 2020, is a fully ambulatory, oral bedaquiline-containing shorter treatment regimen of 9–12 months. Treatment models for RR/MDR-TB of 20–24 months duration have had treatment success rates of 52–66% while shorter treatment regimens have reported success rates of 85% and above. In addition, replacing the second-line injectable agent in a shorter treatment regimen with bedaquiline has been found to further improve treatment success in patients with fluoroquinolone-susceptible RR/MDR-TB. Reliable cost data for RR/MDR-TB care are limited, specifically costs of models that utilize shorter treatment regimens and which are vital to guide Nigeria through the provision of RR/MDR-TB care at scale. We therefore conducted a cost analysis of shorter treatment regimens in use and to be used in Nigeria (Models D, E and F) and compared them to three models of longer duration utilized previously in Nigeria (Models A, B and C) to identify any changes in cost from transitioning from Models A-C to Models D-F and opportunities for cost savings. Methods We obtained costs for TB diagnostic and monitoring tests, in-patient and out-patient care from a previous study, inflated these costs to 2019 NGN and then converted to 2020 USD. We obtained other costs from the average of six health facilities and drug costs from the global drug facility. We modeled treatment on strict adherence to two Nigerian National guidelines for programmatic and clinical management of drug-resistant tuberculosis. Results We estimated that the total costs of care from the health sector perspective for Models D, E and F were $4,334, $7,705 and $3,420 respectively. This is significantly lower than the costs of Models A, B and C which were $14,781, $12, 113, $7,572 respectively. Conclusion Replacing Models A–C with Models D and E reduced the costs of RR/MDR-TB care in Nigeria by approximately $5,470 (48%) per patient treated and transitioning from Models D and E to Model F would result in further cost savings of $914 to $4,285 (21 to 56%) for every patient placed on Model F. If the improved outcomes of patients managed using bedaquiline-containing shorter treatment regimens in other countries can be attained in Nigeria, Model F would be the recommended model for the scale up of RR/MDR-TB care in Nigeria.

544 Background: Sunitinib (SU) and Pazopanib (PZ) have been compared head-to-head in the first-line phase III COMPARZ study in metastatic renal cell carcinoma (mRCC). We compared SU versus PZ, to confirm outcomes and subsequent second-line therapy efficacy in a population-based setting. Methods: We used the IMDC to assess overall survival (OS), progression-free survival (PFS), response rate (RR) and performed proportional hazard regression adjusting for IMDC prognostic groups. Second-line OS2 and PFS2 were also evaluated. Results: We obtained data from 3,606 patients with mRCC treated with either first line SU (n=3226) or PZ (n=380) with an overall median follow-up of 43.5 months (m) (CI95% 41.4 – 46.4). IMDC risk group distribution for favorable prognosis was 440 (17.3%) for SU vs 72 (25%) for PZ, intermediate prognosis 1414 (55.6%) for SU vs 153 (53%) for PZ, poor prognosis 689 (27.1%) for SU vs 62 (22%) for PZ, p= 0.0027. We found no difference between SU vs. PZ for OS (20.1 [CI95% 18.76-21.42] vs. 23.68 m [CI95% 19.54 - 28.81] p=0.19), PFS (7.22 [CI95% 6.76 - 7.78] vs. 6.83 m [CI95% 5.58 - 8.27] p=0.49). The RR was similar in both groups (Table 1). Adjusted HR for OS and PFS were 0.952 (CI95% 0.788 – 1.150 p=0.61) and 1.052 (CI95% 0.908 – 1.220 p = 0.49), respectively. We also found no difference in any second-line treatment between either post-SU vs. post-PZ groups for OS2 (12.88 [CI95% 11.89 – 14.19] vs. 12.91 m [CI95% 10.3 – 19.1] p=0.47) and PFS2 (3.67 [CI95% 3.38 – 3.87] vs. 4.53 m [CI95% 3.08 – 5.35] p=0.4). There was no statistical difference in OS2 and PFS2 if everolimus was used after SU or PZ (p = 0.33 and p = 0.41, respectively) or if axitinib was used after SU or PZ (p = 0.73 and p = 0.72, respectively). Conclusions: We confirmed in real world practice, that SU and PZ have similar efficacy in the first-line setting for mRCC and do not affect outcomes with subsequent second-line treatment.

Abstract Background: Severity of TB increases in refugee populations. Monitoring TB case notification and treatment outcomes are essential to evaluate the effectiveness of TB programs. This study aimed to determine trends in TB case notification and treatment outcomes and explore factors associated with unsuccessful treatment outcome in refugee camps in Ethiopia. Methods: This retrospective cohort study was conducted from October 2018-June 2019. Demographic and clinical data of all TB cases registered from 2014 to 2017 in 25 refugee camps located in seven refugee areas (Shire, Afar, Gambella, Asossa, Mizam, Jijiga, and Dollo Ado) were extracted using pre-tested data extraction format. Multivariate logistic regression was performed to calculate odds ratios and 95% confidence intervals for factors associated with unsuccessful outcomes.Results. A total of 1553 TB cases, mean age 27.7 years, were registered (2014-2017). Of these notified cases 54.7% were men, 27.7% children (< 15 years), 71.2% pulmonary TB (PTB), 27.8% Extra-PTB (EPTB) and 98.3% new and relapse. From 2014 to 2017: there was consistent increase in the number of notified TB cases (138 to 588 cases), in the percentage of EPTB (23.2% to 32.7%), bacteriologically confirmed pulmonary new and relapse (43.8% to 64.8%), and contribution of children to total TB cases (18.8% to 30.1%) and to EPTB (40.6% to 65.1%). Treatment success rates for all TB cases remained lower at 72.7%-79.4% (on average 11.7% were not evaluated, 8.0% lost to follow-up (LTFU), 4.8% died, and 0.5% failed). Unsuccessful treatment was significantly associated with pretreatment weight below 40 Kg, age over 45 years, and being HIV positive.Conclusions: This study has provided valuable evidences that can help to improve the TB programs. There was increased trend in number of notified TB cases, and in proportion of EPTB, childhood TB, and bacteriologically confirmed pulmonary new and relapse cases. Treatment success rate (2014-2017) was far below global target (90%), and “not evaluated” and LTFU treatment outcomes were higher, which need to be improved. Special socio-economic support and monitoring is required for patients with pretreatment weight below 40 Kg, age over 45 years and HIV positives who at risk for unsuccessful treatment.
