Paediatric Tuberculosis

Introduction: Tuberculosis (TB) is the leading infectious disease killer worldwide, despite significant progress against the disease in recent years. Most cases of TB in children occur in the TB endemic countries but the actual burden of paediatric TB is unknown. With early diagnosis and treatment using the first-line anti-tuberculous drugs, most people who develop the disease can be cured and onward transmission of infection curtailed. Objective: To determine the pattern and outcome of paediatric tuberculosis managed at a tertiary facility in Sokoto, Nigeria. Materials and Methods: Records of children managed for TB at the Directly observed treatment short-course (DOTS) clinic over a three-and-a-half-year period were reviewed retrospectively. All children (≤ 15 years) treated for TB over the study period was included. Relevant information was retrieved from the register and analysed accordingly. Results: 74 children were treated with 33(44.6%) being males, giving a M: F ratio of 1:1.2. Mean (±SD) age was 85.78 (±55.40) months and 34 (45.9%) belonged to the 0.0-5.0-year age group. Seventy-one (95.9%) were new cases and three (4.1%) were relapse. Pulmonary TB (PTB) was seen in 50 (67.6%), more females had PTB than males, which was not significant (χ2=0.4, p=0.52). Acid fast bacilli (AFB) were positive in only 8 (10.8%) while GeneXpert MTB/RIF sensitivity was detected in 7 (9.2%). Majority 36 (48.6%) were lost to follow up, 30 (40.5%) completed treatment, only 4(5.4%) were cured with no recorded mortality. Successful treatment outcome was low (45.9%). Conclusion: Treatment outcome using DOTS strategy was poor, far below the WHO benchmark. There is need to improve adherence to DOTs therapy to prevent development of multi drug resistant TB.

Background Germany has a low tuberculosis (TB) incidence. A relevant and increasing proportion of TB cases is diagnosed among asylum seekers upon screening. Aim: We aimed to assess whether cases identified by screening asylum seekers had equally successful and completely reported treatment outcomes as cases diagnosed by passive case finding and contact tracing in the general population. Methods: We analysed characteristics and treatment outcomes of pulmonary TB cases notified in Germany between 2002 and 2014, stratified by mode of case finding. We performed three multivariable analyses with different dependent variables: Model A: successful vs all other outcomes, Model B: successful vs documented non-successful clinical outcome and Model C: known outcome vs lost to follow-up. Results: TB treatment success was highest among cases identified by contact tracing (87%; 3,139/3,591), followed by passive case finding (74%; 28,804/39,019) and by screening asylum seekers (60%; 884/1,474). Cases identified by screening asylum seekers had 2.4 times higher odds of not having a successful treatment outcome as opposed to all other outcomes (A), 1.4 times higher odds of not having a successful treatment outcome as opposed to known non-successful outcomes (B) and 2.3 times higher odds of loss to follow-up (C) than cases identified by passive case finding. Conclusion: Screened asylum seekers had poorer treatment outcomes and were more often lost to follow-up. Linking patients to treatment facilities and investigating potential barriers to treatment completion are needed to secure screening benefits for asylum seekers and communities.

Directly Observed Treatment

Background: Revised National Tuberculosis Control Programme (RNTCP) based on Directly Observed Treatment Short-course (DOTS) strategy has been made available in entire country by March 2006. Given high rate of unfavourable treatment outcomes reported in some provinces, there is a need to analyse outcomes and identify possible trends and associated risk factors that can help for improvement in RNTCP.Methods: After getting Institutional Ethics Committee (IEC) approval, total of 76 cases diagnosed and treated for Tuberculosis (TB) under Category I of RNTCP were recruited from January to March 2017. All patients were followed up for six months from date of initiating the treatment. The data was obtained from TB treatment register, by patient visit and regular follow-up. The information collected include age and gender of patient, category of treatment, date of treatment initiation, initial sputum conversion, outcome of treatment and date of outcome.Results: Out of total 76 patients, 64 (84.21%) were cured, 5 (6.57%) were lost to follow-up, 4 (5.26%) were failed to treat, 1 (1.32%) patient was died, 1 (1.32%) patient had completed treatment but status was unknown and 1 (1.32%) patient was not evaluated because of transfer. Overall treatment outcome of TB patients under DOTS was matching goal of RNTCP with cure rate of 84.21%.Conclusions: Efforts by DOT providers, adequate patient education, motivating ones in need can bring positive outcomes. In this region, DOTS center is at good working condition in terms of functionality as well as ethically. Gender, age group, residence and initial culture colony did not significantly affect treatment outcome.

Lost To Follow Up

BackgroundIn Namibia, one out of every 25 cases of tuberculosis (TB) is “lost to follow-up” (LTFU). This has impacted negatively on national efforts to end the disease by 2035. The aim of this study was to determine the trends and predictors of LTFU under the directly observed treatment short-course (DOTS) programme in Namibia.MethodsThe study involved a retrospective longitudinal analysis of a nationwide cohort of TB cases registered under the DOTS programme in Namibia from 2006 to 2015. The trends and predictors of LTFU among cases in the National Electronic TB Register of the National TB and Leprosy Program were respectively determined by interrupted time series and multivariate logistic regression analyses using R-Studio software.ResultsOut of 104 203 TB cases, 3775 (3.6%) were LTFU. A quarter (26%) of cases with poor outcomes were due to LTFU. The annual decline in cases of LTFU was significant between the first (2005–2010) and second (2010–2015) medium-term plan period for TB programme implementation (p=0.002). The independent predictors of LTFU were male sex (p=0.004), 15–24 years age group (p=0.03), provider of treatment (p<0.001), intensive phase (p=0.047) and living in border/transit regions (p<0.001). HIV co-infection and TB regimen were not significant predictors of LTFU.ConclusionsThere were declining trends in LTFU in Namibia. DOTS programmes should integrate socioeconomic interventions for young and middle-aged adult male TB cases to reduce LTFU.

AbstractTreatment interruption is one of the main risk factors of poor treatment outcome and occurrence of additional drug resistant tuberculosis. This study is a national retrospective cohort study with 10 years follow up period in MDR-TB patients in Ethiopia. We included 204 patients who had missed the treatment at least for one day over the course of the treatment (exposed group) and 203 patients who had never interrupted the treatment (unexposed group). We categorized treatment outcome into successful (cured or completed) and unsuccessful (lost to follow up, failed or died). We described treatment interruption by the length of time between interruptions, time to first interruption, total number of interruption episodes and percent of missed doses. We used Poisson regression model with robust standard error to determine the association between treatment interruption and outcome. 82% of the patients interrupted the treatment in the first six month of treatment period, and considerable proportion of patients demonstrated long intervals between two consecutive interruptions. Treatment interruption was significantly associated with unsuccessful treatment outcome (Adjusted Risk Ratio (ARR) = 1.9; 95% CI (1.4–2.6)). Early identification of patients at high risk of interruption is vital in improving successful treatment outcome.

10558 Background: Previous studies suggested the role of KIT and PDGFRAmutations on treatment outcome of GIST with IMT, but results are heterogeneous. IHC value of PDGFRA and PDGFRB is not established. Methods: We included patients (pts) treated with IMT as a first line therapy for metastastic or relapsed GIST between 2001 and 2008. Tumor DNA was extracted to investigate the mutation status of KITexon 9, exon 11, PDGFRA exon 12 and 18. IHC stain of c-KIT and PDGFRA/B was performed. We assessed the correlation between the treatment outcome, genetic status and IHC results. Results: A total of 85 pts (M:F=49:36, median age 58.4 years) received IMT 400 mg daily. Location of primary disease included stomach (33), small bowel (34), rectum (10), esophagus (1), and omentum/mesentery (7). Complete and partial responses were achieved in 6% and 62% of pts respectively, while 5% of pts had progressive disease. During median follow up of 28.1 months, estimated median PFS was 39.8 months. KIT exon 11 and 9 mutations were detected in 64% and 5% respectively. Exon 11 mutations included 44 deletions, 2 insertions, 5 substitutions and 3 deletion/insertions. PDGFRA exon 12 and 18 mutations were detected in 2% respectively. Positive rate of c-KIT, PDGFRA and PDGFRB using IHC was 96%, 21%, and 26% respectively. PDGFRA and PDGFRB were co-expressed (p=0.001). PDGFRA mutation did not correlate with PDGFRA/B expression. Clinical response was not different according to the mutation status or IHC expression. PFS of KIT exon 11, KITexon 9, PDGFRA mutants and pts without detectable mutations were not different (p=0.397). Pts with KIT exon 11 balanced mutations (substitution or deletion/insertion) showed longer PFS compared with pts with unbalanced mutations (deletion or insertion) (p=0.014) or pts without exon 11 mutations (p=0.033). Median PFS was shorter in pts lacking c-KIT (p=0.001) expression. PDGFRA/B expression did not influence PFS. Conclusions: Balanced mutation of KIT exon 11 predicted longer PFS, while lack of c-KIT protein expression predicted shorter PFS for GIST pts treated with first line IMT. PDGFRA and B were co-expressed without predictive value. No significant financial relationships to disclose.
