Abstract Background Antimicrobial-resistant strains of Streptococcus pneumoniae have become one of the greatest challenges to global public health today and inappropriate use of antibiotics and high level of antibiotic use is probably the main factor driving the emergence of resistance worldwide. The aim of this study is, therefore, to assess the antimicrobial resistance profiles and multidrug resistance patterns of S. pneumoniae isolates from patients suspected of pneumococcal infections in Ethiopia. Methods A hospital-based prospective study was conducted from January 2018 to December 2019 at Addis Ababa city and Amhara National Region State Referral Hospitals. Antimicrobial resistance tests were performed from isolates of S. pneumoniae that were collected from pediatric and adult patients. Samples (cerebrospinal fluid, blood, sputum, eye discharge, ear discharge, and pleural and peritoneal fluids) from all collection sites were initially cultured on 5% sheep blood agar plates and incubated overnight at 37 °C in a 5% CO2 atmosphere. Streptococcus pneumoniae was identified and confirmed by typical colony morphology, alpha-hemolysis, Gram staining, optochin susceptibility, and bile solubility test. Drug resistance testing was performed using the E-test method according to recommendations of the Clinical and Laboratory Standards Institute. Results Of the 57 isolates, 17.5% were fully resistant to penicillin. The corresponding value for both cefotaxime and ceftriaxone was 1.8%. Resistance rates to erythromycin, clindamycin, tetracycline, chloramphenicol and trimethoprim-sulfamethoxazole were 59.6%, 17.5%, 38.6%, 17.5 and 24.6%, respectively. Multidrug resistance (MDR) was seen in 33.3% isolates. The most common pattern was co-resistance to penicillin, erythromycin, clindamycin, and tetracycline. Conclusions Most S. pneumoniae isolates were susceptible to ceftriaxone and cefotaxime. Penicillin has been used as a drug of choice for treating S. pneumoniae infection. However, antimicrobial resistance including multidrug resistance was observed to several commonly used antibiotics including penicillin. Hence, it is important to periodically monitor the antimicrobial resistance patterns to select empirical treatments for better management of pneumococcal infection.

Uzbekistan has a high burden of drug-resistant tuberculosis (TB). Although conventional treatment for multidrug-resistant TB (MDR-TB) and extensively drug-resistant TB (XDR-TB) has been available since 2013, there has been no systematic documentation about its use and effectiveness. We therefore documented at national level the trends, characteristics, and outcomes of patients with drug-resistant TB enrolled for treatment from 2013–2018 and assessed risk factors for unfavorable treatment outcomes (death, failure, loss to follow-up, treatment continuation, change to XDR-TB regimen) in patients treated in Tashkent city from 2016–2017. This was a cohort study using secondary aggregate and individual patient data. Between 2013 and 2018, MDR-TB numbers were stable between 2347 and 2653 per annum, while XDR-TB numbers increased from 33 to 433 per annum. At national level, treatment success (cured and treatment completed) for MDR-TB decreased annually from 63% to 57%, while treatment success for XDR-TB increased annually from 24% to 57%. On multivariable analysis, risk factors for unfavorable outcomes, death, and loss to follow-up in drug-resistant TB patients treated in Tashkent city included XDR-TB, male sex, increasing age, previous TB treatment, alcohol abuse, and associated comorbidities (cardiovascular and liver disease, diabetes, and HIV/AIDS). Reasons for these findings and programmatic implications are discussed.

Background: The shorter regimen was widely accepted and advocated for MDR-TB treatment compared tothe conventional longer regimen. Evaluating the performance of both regimens in a programmatic setting will help in tailoring the treatment regimen of MDR-TB. Objectives: 1. To estimate the duration of sputum smear conversion in the shorter MDR-TB regimen. 2. To compare the treatment outcomes of the shorter MDR-TB regimen with that of the longer conventional MDR regimen in a programmatic set up in India. 3. To estimate the adverse drug reactions in the shorter MDR-TB regimen. Methods: A retrospective cross-sectional study was conducted on 320 patients enrolled under programmatic management of drug resistant tuberculosis (PMDT) from April 2017 to May 2019 at a nodal DRTB center and a tertiary care hospital in India. Demographic and clinical characteristics of those who received a shorter MDR-TB regimen were recorded. Treatment outcomes of both regimens were recorded. Treatment success is defined as ‘disease cured and treatment completed’, whereas treatment failure was considered when the treatment was either terminated or changed due to lack of bacteriological conversion at the end of an extended intensive phase or culture reversion in the continuation phase. Results: The treatment success observed in the shorter MDR-TB regimen was 61.25%, which was significantly higher than the conventional longer regimen (p=0.0007). Treatment failures were higher with a shorter MDR-TB regimen (p=0.0001). Conclusion: Treatment success with the shorter MDR-TB regimen though higher than the conventional regimen, is still way behind the target treatment success rate. Improving treatment adherence remains pivotal for achieving end TB targets.

To improve the unsatisfactory treatment outcomes of multidrug-resistant TB (MDR-TB), it is essential we use new regimens based on newer drugs. To address challenges in the introduction of BDQ and the shorter treatment regimen (STR), the USAID has committed to support countries receiving BDQ (through the USAID/Janssen Bedaquiline Donation Program), with targeted short-term technical assistance (TA). Six MDR-TB clinical consultants were recruited and provided TA to 17 countries between 2017 and 2019. Building on other in-country support, this short-term TA proved instrumental in overcoming barriers, such as misconceptions about BDQ safety, inadequate clinical skills to manage patients and limited expansion plans to increase access to BDQ and the STR.

Abstract Background In 2018, malnutrition contributed to 45% of all global cause of child death. These early child deaths were due to conditions that could either be prevented or treated with basic interventions. Hence, this study intended to provide a quantitative estimate of factors associated with undesirable treatment outcomes of severe acute malnutrition (SAM). Methods We studied a retrospective cohort of 304 children aged 6–59 months with complicated SAM admitted to Yekatit 12 Hospital Medical College from 2013 to 2016. We extracted data from hospital records on nutritional status, socio-demographic factors and medical conditions during admission. The analysis was carried out using SPSS version 20. The Kaplan-Meier estimator was employed to analyze the recovery rate of the children treated for SAM and multivariable Cox regression was used to determine factors that predict inpatient undesirable treatment outcomes. Result From a total of 304 children 6–59 months with SAM, 133 (51.4%) were boys. Marasmus was the most common type (132 (51%)) of severe acute malnutrition. The recovery, death and defaulter rate were 70.4, 12.2 and 8.2% respectively. The main predictors of undesirable treatment outcomes were found to be the presence of HIV antibody (AHR = 3.208; 95% CI: [1.045–9.846]) and sepsis (AHR = 7.677, 95% CI: [2.320–25.404]). Conclusion The study revealed that the overall treatment outcomes were below the SPHERE standard recommendation. The main predictors of undesirable treatment outcomes among inpatient children treated for SAM were HIV and sepsis. Intervention to reduce undesirable treatment outcomes should focus on comorbidities, especially HIV and sepsis.
