First results from the lessons learnt from the deployment of the Med Safety App for reporting adverse drug reactions in Ghana.

Background: The use of mobile phone technology for reporting adverse drug reactions (ADRs) in pharmacovigilance is relatively new.The objective of the study was to explore challenges and facilitators for the use of the Med Safety App for reporting ADRs in Ghana. A comparative evaluation of ADR reports received through the app and the standard paper-based form was also conducted. Methods: This was a cross-sectional study with a purposive sampling technique. The study population was persons who had downloaded the Med Safety App launched in Ghana 18 months before the study. Results: Of the 350 participants, 121 provided answers to the questionnaire sent as a Google form, representing a response rate of 34.6%.Ninety-five (78.5%) of the participants were healthcare professionals, and the remaining were patients. Seventy-five (64.7%) of the participants were using the app after initial installation because they thought it had helpful features. However, only 33 (27.3%) participants used the app to report ADRs, and of these, seven (21.2%) participants indicated that they would continue to use the app because it was easier than the other means of reporting ADRs. Most of the respondents, 109 (94%), indicated that they would recommend the app to someone else. There were some differences between the reports received through the app and between the paper-based Council for International Organizations of Medical Sciences (CIOMS) 1 form and the app, which warrant further exploration. Conclusion: Most participants indicated that the app is a useful tool and easy to use, and they were satisfied with the features of the app. Given that only just under one-third of participants had used the app to report ADRs, more time and training may be required to fully evaluate the feasibility of the use of the app going forward. The findings will help improve introduction of the app in other countries.

Implementation of a peer support intervention to promote the detection, reporting and management of adverse drug reactions in people living with HIV in Uganda: a protocol for a quasi-experimental study.

INTRODUCTION: Patients have contributed <1% of spontaneous adverse drug reaction (ADR) reports in Uganda's pharmacovigilance database. Peer support combined with mobile technologies could empower people living with HIV (PLHIV) to report ADRs and improve ADR management through linkage to care. We seek to test the feasibility and effect of a peer support intervention on ADR reporting by PLHIV receiving combination antiretroviral therapy (cART) in Uganda; identify barriers and facilitators to the intervention; and characterise ADR reporting and management. METHODS AND ANALYSIS: This is a quasi-experimental study to be implemented over 4 months at 12 intervention and 12 comparison cART sites from four geographical regions of Uganda. Per region, two blocks each with a tertiary, secondary and primary care cART site will be selected by simple random sampling. Blocks per region will be randomly assigned to intervention and comparison arms.Study units will include cART sites and PLHIV receiving cART. PLHIV at intervention sites will be assigned to peer supporters to empower them to report ADRs directly to the National Pharmacovigilance Centre (NPC). Peer supporters will be expert clients from among PLHIV and/or recognised community health workers.Direct patient reporting of ADRs to NPC will leverage the Med Safety App and toll-free unstructured supplementary service data interface to augment traditional pharmacovigilance methods.The primary outcomes are attrition rate measured by number of study participants who remain in the study until the end of follow-up at 4 months; and number of ADR reports submitted to NPC by PLHIV as measured by questionnaire and data abstraction from the national pharmacovigilance database at baseline and 4 months. ETHICS AND DISSEMINATION: The study received ethical approval from: School of Health Sciences Research and Ethics Committee at Makerere University (MAKSHSREC-2020-64) and Uganda National Council for Science and Technology (HS1206ES). Results will be shared with PLHIV, policy-makers, the public and academia. TRIAL REGISTRATION NUMBER: ISRCTN75989485.

Epidemiological surveillance linked to an outreach psychological support program after the Xynthia storm in Charente-Maritime, France, 2010.

INTRODUCTION: Following the Xynthia storm of February 2010 in France, an outreach program was initiated by the regional health authorities during the post-emergency phase to improve access to mental health care for the population exposed to the floods. The program was designed to complement routine health and social care services. It relied on a special telephone service and outreach consultations located in the town halls of the five most affected cities. The objective of this outreach service was to provide initial psychological counseling free of charge and without appointment. Another objective was to refer persons for appropriate treatment and follow-up by routine health care services. A surveillance program was developed to monitor the use of mental health services by first-time users, describe outreach service users with psychological manifestations, and provide timely information to decision makers. METHODS: Health providers working in affected towns were asked to complete an individual record sheet for each person who displayed psychological manifestations directly or indirectly linked with the storm on their first visit, and to send it to the regional health office. Participation was voluntary. Data analysis was performed monthly during the six-month surveillance period. RESULTS: Only mental health providers participated in the surveillance. A total of 227 individual files were sent from April 7 through September 19, 2010. New cases were mainly female adults, and one fifth had a past history of psychiatric illness. Depressive signs and anxiety were the most commonly reported symptoms, followed by signs of post-traumatic stress disorder. A total of five feedback reports were produced for surveillance participants (informants) and authorities. CONCLUSION: With initiation in the post-emergency phase of a disaster and timely regular feedback, the surveillance program enabled the authors to describe the occurrence of psychological distress, monitor mental health service use by first-time users, and provide guidance to health authorities. This research showed the advantages of integrating epidemiology in the development of strategy for mental health and psychosocial support in the aftermath of natural catastrophes.

High survival and treatment success sustained after two and three years of first-line ART for children in Cambodia.

BACKGROUND: Long-term outcomes of antiretroviral therapy (ART) in children remain poorly documented in resource-limited settings. The objective of this study was to assess two-and three-year survival, CD4 evolution and virological response among children on ART in a programmatic setting in Cambodia. METHODS: Children treated with first-line ART for at least 24 months were assessed with viral load testing and genotyping. We used Kaplan-Meier analysis for survival and Cox regression to identify risk factors associated with treatment failure. RESULTS: Of 1168 registered HIV-positive children, 670 (57%) started ART between January 2003 and December 2007. Survival probability was 0.93 (95% CI: 0.91-0.95) and 0.91 (95% CI: 0.88-0.93) at 24 and 36 months after ART initiation, respectively. Median CD4 gain for children aged over five years was 704 cells/mm3 at 24 months and 737 at 36 months. Median CD4 percentage gain for children under five years old was 15.2% at 24 months and 15% at 36 months. One hundred and thirty children completed at least 24 months of ART, and 138 completed 36 months: 128 out of 268 (48%) were female. Median age at ART initiation was six years.Overall, 22 children had viral loads of >1000 copies/ml (success ratio = 86% on intention-to-treat-analysis) and 21 of 21 presented mutations conferring resistance mostly to lamivudine and non-nucleoside reverse transcriptase inhibitors. Risk factors for failure after 24 and 36 months were CD4 counts below the threshold for severe immunosupression at those months respectively. Only two out of 22 children with viral loads of >1000 copies/ml met the World Health Organization immunological criteria for failure (sensitivity = 0.1). CONCLUSIONS: Good survival, immunological restoration and viral suppression can be sustained after two to three years of ART among children in resource-constrained settings. Increased access to routine virological measurements is needed for timely diagnosis of treatment failure.

Excellent outcomes among HIV+ children on ART, but unacceptably high pre-ART mortality and losses to follow-up: a cohort study from Cambodia.

BACKGROUND: Although HIV program evaluations focusing on mortality on ART provide important evidence on treatment effectiveness, they do not asses overall HIV program performance because they exclude patients who are eligible but not started on ART for whatever reason. The objective of this study was to measure mortality that occurs both pre-ART and during ART among HIV-positive children enrolled in two HIV-programs in Cambodia. METHODS: Retrospective cohort study on 1168 HIV-positive children <15 years old registered in two HIV-programs over a four-year period. Mortality rates were calculated for both children on treatment and children not started on ART. RESULTS: Over half (53%) of children were 5 years or above and only 69(6%) were <18 months. Overall, 9% (105/1168) of children died since the set-up of the programs. By the end of the observation period, 66(14.5%) patients not on ART had died compared to 39(5.5%) of those under treatment, and 100(22%) who did not start ART were lost-to-follow-up compared to 13(2%) on ART. 66/105 (62.8%) of all in-program deaths occurred before starting ART, of which 56% (37/66) and 79% (52/66) occurred within 3 and 6 months of enrollment respectively. Mortality rate ratio between children not on ART and children on ART was 4.1 (95%CI: 2.7-6.2) (P < 0.001). The most common contributing cause of death in first 3 months of treatment and in first 3 months of program enrollment was tuberculosis. 41/52 (79%) children who died within 6 months of enrollment had met the ART eligibility criteria before death. CONCLUSION: HIV-positive children experienced a high mortality and loss-to-follow-up rates before starting ART. These program outcomes may be improved by a more timely ART initiation. Measuring overall in-program mortality as opposed to only mortality on ART is recommended in order to more accurately evaluate pediatric HIV-programs performance.

Treating 4,000 diabetic patients in Cambodia, a high-prevalence but resource-limited setting: a 5-year study.

BACKGROUND: Despite the worldwide increasing burden of diabetes, there has been no corresponding scale-up of treatment in developing countries and limited evidence of program effectiveness. In 2002, in collaboration with the Ministry of Health of Cambodia, Médecins Sans Frontières initiated an outpatient program of subsidized diabetic care in two hospital-based chronic disease clinics in rural settings. We aimed to describe the outcomes of newly and previously diagnosed diabetic patients enrolled from 2002 to 2008. METHODS: We calculated the mean and proportion of patients who met the recommended treatment targets, and the drop from baseline values for random blood glucose (RBG), hemoglobin A1c (HbA1c), blood pressure (BP), and body mass index (BMI) at regular intervals. Analysis was restricted to patients not lost to follow-up. We used the t test to compare baseline and subsequent paired values. RESULTS: Of 4404 patients enrolled, 2,872 (65%) were still in care at the time of the study, 24 (0.5%) had died, and 1,508 (34%) were lost to follow-up. Median age was 53 years, 2,905 (66%) were female and 4,350 (99%) had type 2 diabetes. Median (interquartile range (IQR)) follow-up was 20 months (5 to 39.5 months). A total of 24% (51/210) of patients had a HbA1c concentration of <7% and 35% (709/1,995) had a RBG <145 mg/dl within 1 year. There was a significant drop of 109 mg/dl (95% confidence interval (CI) 103.1 to 114.3) in mean RBG (P < 0.001) and a drop of 2.7% (95% CI 2.3 to 3.0) in mean HbA1c (P < 0.001) between baseline and month 6. In all, 45% (327/723) and 62% (373/605) of patients with systolic or diastolic hypertension at baseline, respectively, reached = 130/80 mm Hg within 1 year. There was a drop of 13.5 mm Hg (95% CI 12.1 to 14.9) in mean systolic blood pressure (SBP) (P < 0.001), and a drop of 11.7 mm Hg (95% CI 10.8 to 12.6) in mean diastolic blood pressure (DBP) (P < 0.001) between baseline and month 6. Only 22% (90/401) patients with obesity at baseline lowered their BMI <27.5 kg/m2 after 1 year. Factors associated with loss to follow-up were male sex, age >60 years, living outside the province, normal BMI on admission, high RBG on last visit, and coming late for the last consultation. CONCLUSION: Significant and clinically important improvements in glycemia and BP were observed, but a relatively low proportion of diabetic patients reached treatment targets. These results and the high loss to follow-up rate highlight the challenges of delivering diabetic care in rural, resource-limited settings.

Effectiveness of melarsoprol and eflornithine as first-line regimens for gambiense sleeping sickness in nine Médecins Sans Frontières programmes.

This paper describes the effectiveness of first-line regimens for stage 2 human African trypanosomiasis (HAT) due to Trypanosoma brucei gambiense infection in nine Médecins Sans Frontières HAT treatment programmes in Angola, Republic of Congo, Sudan and Uganda. Regimens included eflornithine and standard- and short-course melarsoprol. Outcomes for 10461 naïve stage 2 patients fitting a standardised case definition and allocated to one of the above regimens were analysed by intention-to-treat analysis. Effectiveness was quantified by the case fatality rate (CFR) during treatment, the proportion probably and definitely cured and the Kaplan-Meier probability of relapse-free survival at 12 months and 24 months post admission. The CFR was similar for the standard- and short-course melarsoprol regimens (4.9% and 4.2%, respectively). The CFR for eflornithine was 1.2%. Kaplan-Meier survival probabilities varied from 71.4-91.8% at 1 year and 56.5-87.9% at 2 years for standard-course melarsoprol, to 73.0-91.1% at 1 year for short-course melarsoprol, and 79.9-97.4% at 1 year and 68.6-93.7% at 2 years for eflornithine. With the exception of one programme, survival at 12 months was >90% for eflornithine, whilst for melarsoprol it was <90% except in two sites. Eflornithine is recommended where feasible, especially in areas with low melarsoprol effectiveness.

Evaluation of a systematic substitution of zidovudine for stavudine-based HAART in a program setting in rural Cambodia.

OBJECTIVE: To evaluate a treatment strategy of substituting zidovudine (ZDV) for stavudine (d4T)-based highly active antiretroviral therapy (HAART), aimed at preventing d4T-associated toxicity, in a programmatic setting in rural Cambodia. METHODS: Survival probability, CD4 gain, anemia incidence, and factors associated with severe anemia were analyzed in a cohort of adult patients switched from d4T- to ZDV-containing regimens from March 2006 to March 2007. RESULTS: Among 527 patients systematically switched to ZDV after d4T-based HAART for a median of 18 months, 4 (0.8%) patients died, 2 (0.4%) were lost to follow-up, 18 (3.4%) were transferred out, and 503 (95.4%) remained on HAART. Median CD4 gain was +263.5 cells/microL (interquartile range: 89.25-369.5) at 24 months. Within 1 year after the switch, 21.9% and 7.1% of patients developed anemia (grades 1-4) and severe anemia (grades 3-4), respectively. Low body mass index (< or =18) and low CD4 count (<200 cells/microL) at the time of switch were factors associated with severe anemia. Additional follow-up visits for laboratory monitoring and adherence counseling, increased absenteeism from work, and transportation costs for the patients were noted. CONCLUSIONS: The switch strategy of substituting ZDV for d4T-based HAART led to satisfactory overall clinical outcomes. However, it resulted in a relatively high incidence of mild to severe anemia and increased burden for the program and the patients.

Epidemiology and clinical features of patients with visceral leishmaniasis treated by an MSF clinic in Bakool region, Somalia, 2004-2006.

BACKGROUND: There are few reports describing the epidemiology of visceral leishmaniasis (VL) in Somalia. Over the years 2002 to 2005, a yearly average of 140 patients were reported from the Huddur centre in Bakool region, whereas in 2006, this number rose to 1002 patients. Given the limited amount of information on VL and the opportunity to compare features with the studies done in 2000 in this part of Somalia, we describe the epidemiologic and clinical features of patients who presented to the Huddur treatment centre of Bakool region, Somalia, using data routinely collected over a five-year observation period (2002-2006). METHODOLOGY: Methods used included the analysis of routine data on VL cases treated in the Huddur treatment centre, a retrospective study of records of patients admitted between 2004 and 2006, community leaders interviews, and analysis of blood specimens taken for parasite species identification in Antwerp Institute of Tropical Medicine. PRINCIPAL FINDINGS: A total of 1671 VL patients were admitted to the Huddur centre from January 2002 until December 2006. Nearly all patients presented spontaneously to the health centre. Since 2002, the average patient load was stable, with an average of 140 admissions per year. By the end of 2005, the number of admissions dramatically increased to reach a 7-fold increase in 2006. The genotype of L. donovani identified in 2006 was similar to the one reported in 2002. 82% of total patients treated for VL originated from two districts of Bakool region, Huddur and Tijelow districts. Clinical recovery rate was 93.2% and case fatality rate 3.9%. CONCLUSIONS: After four years of low but constant VL case findings, a major increase in VL was observed over a 16-month period in the Huddur VL centre. The profile of the patients was pediatric and mortality relatively low. Decentralized treatment centers, targeted active screening, and community sensitization will help decrease morbidity and mortality from VL in this endemic area. The true magnitude of VL in Somalia remains unknown. Further documentation to better understand transmission dynamics and thus define appropriate control measures will depend on the stability of the context and safe access to the Somali population.
