Hearing aid support for patients with DR-TB in Ethiopia.

SETTING: Previous and current patients with drug-resistant TB (DR-TB) who had documented treatment-related hearing impairment due to second-line injectable (SLI) use were identified from different DR-TB treatment initiation centres in Ethiopia. OBJECTIVE: To assess selected patients with DR-TB for eligibility for hearing aids and provide hearing aids to 10 eligible patients. DESIGN: This was an observational cohort study. Patients were followed up for 8 months, with hearing assessments conducted at 1, 3 and 8 months to objectively assess hearing capacity. RESULTS: Of 12 patients assessed for hearing aids eligibility, 10 were fitted with hearing aids (type XTM XP P4) and followed up for 8 months. "Formal" improvement was observed only in one patient. However, "general quality of life" appeared to be improved in nine patients. CONCLUSION: Minimal "formal" improvement was observed. However, the study was too small to say whether hearing aids should, or should not, be recommended as a public health measure. This needs a larger better controlled follow-up study. The all-oral DR-TB treatment regimens should be used for all patients with DR-TB in Ethiopia. However, as a proportion of patients with DR-TB are likely to continue receiving SLIs in the foreseeable future, they will require close audiometry assessment and appropriate care.

CONTEXTE: Les patients, anciens et actuels, atteints de TB pharmacorésistante (DR-TB) ayant une déficience auditive documentée due à l'utilisation d'agents injectables de seconde ligne (SLI), ont été identifiés dans différents centres de traitement de la DR-TB en Éthiopie. OBJECTIF: Évaluer l'éligibilité des patients atteints de DR-TB sélectionnés à une aide auditive et fournir cette dernière à 10 patients éligibles. MÉTHODE: Il s'agissait d'une étude de cohorte observationnelle. Les patients ont été suivis pendant 8 mois, avec examens auditifs à 1, 3 et 8 mois pour évaluer de manière objective leur capacité auditive. RÉSULTATS: Sur 12 patients évalués pour éligibilité à une aide auditive, 10 ont été équipés (type XTM XP P4) et suivis pendant 8 mois. Une amélioration « formelle ¼ a été observée chez seulement un patient, mais la « qualité de vie globale ¼ de neuf patients semble s'être améliorée. CONCLUSION: Une amélioration « formelle ¼ minime a été observée. L'étude était cependant trop petite pour pouvoir recommander ou non les aides auditives en tant que mesure de santé publique. Une étude de suivi mieux contrôlée et plus vaste est nécessaire. Les schémas thérapeutiques entièrement par voie orale de la DR-TB doivent être utilisés chez tous les patients atteints de la maladie en Éthiopie. Cependant, puisque certains patients atteints de DR-TB sont susceptibles de continuer à recevoir des SLI dans un futur proche, un contrôle étroit par audiométrie et des soins appropriés seront nécessaires.

Experiences of introducing new drugs for drug-resistant TB at the ALERT Hospital, Addis Ababa, Ethiopia, 2017-2019.

BACKGROUND: Drug-resistant TB (DR-TB) remains a major public health concern. DR-TB patient data from ALERT (All Africa Leprosy, Tuberculosis and Rehabilitation Training Centre) Hospital, Addis Ababa, Ethiopia, who received bedaquiline (BDQ) and/or delamanid (DLM) containing regimens were analysed. RESULTS: From 2017 to 2019, 51 DR-TB patients were enrolled. Of 33 patients, 31 (93.9%) had culture converted at 6 months. Of those with final outcomes, 77% (n = 10) were cured. Thirty (58.8%) developed adverse events, the most frequent of which were gastrointestinal disorders (70%), haematological disorders (16.7%) and QTc prolongation (16.7%). Twenty patients discontinued the offending drug permanently. CONCLUSION: With close monitoring, introduction of new DR-TB regimens brought good early results, which encouraged wider programmatic implementation in Ethiopia.

CONTEXTE: La TB pharmacorésistante (DR-TB) reste une préoccupation de santé publique majeure. Les données des patients DR-TB de l'hôpital ALERT (All Africa Leprosy, Tuberculosis and Rehabilitation Training Centre, Addis Ababa, Ethiopie) qui ont reçu des protocoles contenant de la bédaquiline et/ou du délamanide ont été analysées. RÉSULTATS: Des 51 patients DR-TB ont été enrôlés de 2017 à 2019, 90 ont eu une conversion de culture à 6 mois, 77% ont été guéris, 30 ont eu des effets secondaires, les plus fréquents étant des troubles gastro-intestinaux (70%), des troubles hématologique (16,7%) et un allongement de QTc (16,7%). Vingt patients ont définitivement arrêté le médicament incriminé. CONCLUSION: Moyennant une surveillance étroite, l'introduction de nouveaux protocoles DR-TB a eu de bons résultats précoces qui encouragent une mise en œuvre programmatique plus large en Ethiopie.

Evaluating the integration of tuberculosis screening and contact investigation in tuberculosis clinics in Ethiopia: A mixed method study.

BACKGROUND: Aligned with global childhood tuberculosis (TB) road map, Ethiopia developed its own in 2015. The key strategies outlined in the Ethiopian roadmap are incorporating TB screening in Integrated Maternal, Neonatal and Child Illnesses (IMNCI) clinic for children under five years (U5) and intensifying contact investigations at TB clinic. However, these strategies have never been evaluated. OBJECTIVE: To evaluate the integration of tuberculosis (TB) screening and contact investigation into Integrated Maternal, Neonatal and Child Illnesses (IMNCI) and TB clinics in Addis Ababa, Ethiopia. METHODS: The study used mixed methods with stepped-wedge design where 30 randomly selected health care facilities were randomized into three groups of 10 during August 2016-November 2017. The integration of TB screening into IMNCI clinic and contact investigation in TB clinic were introduced by a three-day childhood TB training for health providers. An in-depth interview was used to explore the challenges of the interventions and supplemented data on TB screening and contact investigation. RESULTS: Overall, 180896 children attended 30 IMNCI clinics and145444 (80.4%) were screened for TB. A total of 688 (0.4%) children had presumptive TB and 47(0.03%) had TB. During the pre-intervention period, 51873 of the 85278 children (60.8%) were screened for TB as compared to 93570 of the 95618 children (97.9%) in the intervention (p<0.001). This had resulted in 149 (0.30%) and 539 (0.6%) presumptive TB cases in pre-intervention and intervention periods (p<0.001), respectively. Also, nine TB cases (6.0%) in pre-intervention and 38 (7.1%) after intervention were identified (p = 0.72). In TB clinics, 559 under-five (U5) contacts were identified and 419 (80.1%) were screened. In all, 51(9.1%) presumed TB cases and 12 (2.1%) active TB cases were identified from the traced contacts. TB screening was done for 182 of the 275 traced contacts (66.2%) before intervention and for 237 of the 284 of the traced (83.5%) under intervention (p<0.001). Isoniazid prevention therapy (IPT) was initiated for 69 of 163 eligible contacts (42.3%) before intervention and for 159 of 194 eligible children (82.0%) under intervention (p<0.001). Over 95% of health providers indicated that the integration of TB screening into IMNCI and contact investigation in TB clinic is acceptable and practical. Gastric aspiration to collect sputum using nasogastric tube was reported to be difficult. CONCLUSIONS: Integrating TB screening into IMNCI clinics and intensifying contact investigation in TB clinics is feasible improving TB screening, presumed TB cases, TB cases, contact screening and IPT coverage during the intervention period. Stool specimen could be non-invasive to address the challenge of sputum collection.

Avidity of IgG antibodies against meningococcal serogroup a polysaccharide and correlations with bactericidal activity in sera from meningitis patients and controls from Ethiopia.

Meningococcal meningitis is a significant global health challenge, especially for sub-Saharan area: the African meningitis belt. Neisseria meningitidis of serogroup A (MenA) is responsible for the large number of epidemics that have been recorded in these countries. To determine the level of antibodies against meningococcal A polysaccharide (APS) that correlates with protection against MenA disease in the African meningitis belt, it may be important to consider antibody avidity along with quantity. In this study, two ELISA methods using the chaotropic agent ammonium thiocyanate were compared and employed to measure avidity indexes (AI) of IgG antibodies against APS in controls and in acute and convalescent sera from Ethiopian meningococcal patients. High statistical correlations between the AIs determined by the two methods were observed. The geometric mean AI (GMAI) increased with time from acute to convalescent sera indicating affinity maturation. GMAI was significantly higher in convalescent sera from the MenA patients and in sera from the controls than in acute sera from patients with meningococcal disease. A significant correlation between serum bactericidal activity titres (SBA) and concentration of IgG antibodies against APS was observed; however, our results did not indicate that determination of antibody avidities by the thiocyanate elution method gave a better correlation with SBA than anti-APS IgG concentrations determined by the standard ELISA method.
