Circumstances of child deaths in Mali and Uganda: a community-based confidential enquiry.

BACKGROUND: Interventions to reduce child deaths in Africa have often underachieved, causing the Millennium Development Goal targets to be missed. We assessed whether a community enquiry into the circumstances of death could improve intervention effectiveness by identifying local avoidable factors and explaining implementation failures. METHODS: Deaths of children younger than 5 years were ascertained by community informants in two districts in Mali (762 deaths) and three districts in Uganda (442 deaths) in 2011-15. Deaths were investigated by interviewing parents and health workers. Investigation findings were reviewed by a panel of local health-care workers and community representatives, who formulated recommendations to address avoidable factors and, subsequently, oversaw their implementation. FINDINGS: At least one avoidable factor was identified in 97% (95% CI 96-98, 737 of 756) of deaths in children younger than 5 years in Mali and 95% (93-97, 389 of 409) in Uganda. Suboptimal newborn care was a factor in 76% (146 of 194) of neonatal deaths in Mali and 64% (134 of 194) in Uganda. The most frequent avoidable factor in postneonatal deaths was inadequate child protection (mainly child neglect) in Uganda (29%, 63 of 215) and malnutrition in Mali (22%, 124 of 562). 84% (618 of 736 in Mali, 328 of 391 in Uganda) of families had consulted a health-care provider for the fatal illness, but the quality of care was often inadequate. Even in official primary care clinics, danger signs were often missed (43% of cases in Mali [135 of 396], 39% in Uganda [30 of 78]), essential treatment was not given (39% in Mali [154 of 396], 35% in Uganda [27 of 78]), and patients who were seriously ill were not referred to a hospital in time (51% in Mali [202 of 396], 45% in Uganda [35 of 78]). Local recommendations focused on quality of care in health-care facilities and on community issues influencing treatment-seeking behaviour. INTERPRETATION: Local investigation and review of circumstances of death of children in sub-Saharan Africa is likely to lead to more effective interventions than simple consideration of the biomedical causes of death. This approach discerned local public health priorities and implementable solutions to address the avoidable factors identified.

Human resources for primary health care in sub-Saharan Africa: progress or stagnation?

BACKGROUND: The World Health Organization defines a "critical shortage" of health workers as being fewer than 2.28 health workers per 1000 population and failing to attain 80% coverage for deliveries by skilled birth attendants. We aimed to quantify the number of health workers in five African countries and the proportion of these currently working in primary health care facilities, to compare this to estimates of numbers needed and to assess how the situation has changed in recent years. METHODS: This study is a review of published and unpublished "grey" literature on human resources for health in five disparate countries: Mali, Sudan, Uganda, Botswana and South Africa. RESULTS: Health worker density has increased steadily since 2000 in South Africa and Botswana which already meet WHO targets but has not significantly increased since 2004 in Sudan, Mali and Uganda which have a critical shortage of health workers. In all five countries, a minority of doctors, nurses and midwives are working in primary health care, and shortages of qualified staff are greatest in rural areas. In Uganda, shortages are greater in primary health care settings than at higher levels. In Mali, few community health centres have a midwife or a doctor. Even South Africa has a shortage of doctors in primary health care in poorer districts. Although most countries recognize village health workers, traditional healers and traditional birth attendants, there are insufficient data on their numbers. CONCLUSION: There is an "inverse primary health care law" in the countries studied: staffing is inversely related to poverty and level of need, and health worker density is not increasing in the lowest income countries. Unless there is money to recruit and retain staff in these areas, training programmes will not improve health worker density because the trained staff will simply leave to work elsewhere. Information systems need to be improved in a way that informs policy on the health workforce. It may be possible to use existing resources more cost-effectively by involving skilled staff to supervise and support lower level health care workers who currently provide the front line of primary health care in most of Africa.

Pre-hospital risk factors for inpatient death from severe febrile illness in Malian children.

BACKGROUND: Inpatient case fatality from severe malaria remains high in much of sub-Saharan Africa. The majority of these deaths occur within 24 hours of admission, suggesting that pre-hospital management may have an impact on the risk of case fatality. METHODS: Prospective cohort study, including questionnaire about pre-hospital treatment, of all 437 patients admitted with severe febrile illness (presumed to be severe malaria) to the paediatric ward in Sikasso Regional Hospital, Mali, in a two-month period. FINDINGS: The case fatality rate was 17.4%. Coma, hypoglycaemia and respiratory distress at admission were associated with significantly higher mortality. In multiple logistic regression models and in a survival analysis to examine pre-admission risk factors for case fatality, the only consistent and significant risk factor was sex. Girls were twice as likely to die as boys (AOR 2.00, 95% CI 1.08-3.70). There was a wide variety of pre-hospital treatments used, both modern and traditional. None had a consistent impact on the risk of death across different analyses. Reported use of traditional treatments was not associated with post-admission outcome. INTERPRETATION: Aside from well-recognised markers of severity, the main risk factor for death in this study was female sex, but this study cannot determine the reason why. Differences in pre-hospital treatments were not associated with case fatality.

Chromatographic immunoassays for Helicobacter pylori detection--are they reliable in Mali, West Africa?

INTRODUCTION: Gastrointestinal diseases are major reasons for morbidity in Mali. As Helicobacter pylori is known to play a major role in gastritis and gastric ulcer we wanted to find a simple method for detection. METHODS: Twenty-nine volunteers with confirmed gastric ulcer by gastroscopy and 59 randomly selected volunteers were diagnosed by using the rapid serological test Clearview(®) H. Pylori. The ImmunoCard STAT!(®) HpSA(®)test was applied on stool from 65 volunteers seeking help for gastrointestinal related ailments. RESULTS: A Helicobacter pylori prevalence of 21% was found among the individuals with confirmed gastric ulcer, 44% among the randomly selected volunteers and 14% in individuals with gastrointestinal related ailments. CONCLUSION: According to what is already known about the aetiology of gastric ailments and the prevalence of Helicobacter pylori in neighboring countries, the infection rates in our study appear strikingly low. This might indicate that Clearview(®) H. Pylori and ImmunoCard STAT!(®) HpSA(®) have low sensitivities in the populations studied. Strain variability of H. pylori may be an explanation. The tests need to be properly evaluated in Mali before they can be relied upon as diagnostic tools.

A "reverse pharmacology" approach for developing an anti-malarial phytomedicine.

A "reverse pharmacology" approach to developing an anti-malarial phytomedicine was designed and implemented in Mali, resulting in a new standardized herbal anti-malarial after six years of research. The first step was to select a remedy for development, through a retrospective treatment-outcome study. The second step was a dose-escalating clinical trial that showed a dose-response phenomenon and helped select the safest and most efficacious dose. The third step was a randomized controlled trial to compare the phytomedicine to the standard first-line treatment. The last step was to identify active compounds which can be used as markers for standardization and quality control. This example of "reverse pharmacology" shows that a standardized phytomedicine can be developed faster and more cheaply than conventional drugs. Even if both approaches are not fully comparable, their efficiency in terms of public health and their complementarity should be thoroughly considered.

Is parasite clearance clinically important after malaria treatment in a high transmission area? A 3-month follow-up of home-based management with herbal medicine or ACT.

Argemone mexicana (AM), a validated herbal medicine for uncomplicated malaria, seems to prevent severe malaria without completely clearing parasites in most patients. This study, in a high transmission area of South Mali, explores whether residual parasitaemia at day 28 was associated with subsequent malaria episodes and/or anaemia. Three hundred and one patients were randomly assigned to AM or artesunate/amodiaquine as first line treatment, of whom 294 were followed up beyond the standard 28 days, to 84 days. From day 29 to day 84, there were no significant differences between treatment groups in new clinical episodes of uncomplicated malaria (0.33 vs 0.31 episodes/patient), severe malaria (< 6% per month of patients aged ≤ 5 years) or moderate anaemia (hematocrit < 24%: 1.1% in both groups at day 84). Total parasite clearance at day 28 was not correlated with incidence of uncomplicated or severe malaria or of moderate anaemia over the subsequent two months. Total parasite clearance at day 28 was not clinically important in the context of high transmission. If this finding can be confirmed, some antimalarials which are clinically effective but do not completely clear parasites could nevertheless be appropriate in high transmission areas. Such a policy could be tested as a way to delay resistance to artemisinin combination therapies.

[Study of the consumption of the Improved Traditional Phytomedicines in the health district of Kadiolo (Region of Sikasso, Mali)]. / Etude de la consommation des Medicaments Traditionnels Ameliores dans le district sanitaire de Kadiolo (Region de Sikasso, Mali).

The study, which received the support of the Development and Co-operation Management of the Swiss Confederation in the frame of the Socio-Sanitary Support Program Mali-Switzerland, proceeded from February to March 2004. The goal was to evaluate the impact of a workshop of formation of the prescribers on the Improved Traditional Phytomedicines (ITP), carried out in October 2001, on the consumption of the ITP in the medical structures of the District of Kadiolo. The study required the data-gathering of consumption, starting from the cards of stock of the years 2001, 2002 and 2003 of the Distributor Warehouse of the Reference Health Center and of the Pharmacies of the Community Health Centers. To evaluate the appreciation of the ITP, the investigations were carried out near the prescribers and the users. The overall consumption of ITP in CSRéf and 16 CSCom of the District knew a progressive increase, while passing from 2 565 480 F CFA in 2001 to 4 307 760 F CFA in 2003. The consumption of ITP during the year 2003 was of 27.83 F CFA per capita. The ITP in general were well appreciated by the prescribers and the consumers. Various projections of the consumption data recorded in Kadiolo allowed considering the potential market of the ITP currently available in Mali with a value ranging between 414 and 560 millions of F CFA.

Argemone mexicana decoction versus artesunate-amodiaquine for the management of malaria in Mali: policy and public-health implications.

A classic way of delaying drug resistance is to use an alternative when possible. We tested the malaria treatment Argemone mexicana decoction (AM), a validated self-prepared traditional medicine made with one widely available plant and safe across wide dose variations. In an attempt to reflect the real situation in the home-based management of malaria in a remote Malian village, 301 patients with presumed uncomplicated malaria (median age 5 years) were randomly assigned to receive AM or artesunate-amodiaquine [artemisinin combination therapy (ACT)] as first-line treatment. Both treatments were well tolerated. Over 28 days, second-line treatment was not required for 89% (95% CI 84.1-93.2) of patients on AM, versus 95% (95% CI 88.8-98.3) on ACT. Deterioration to severe malaria was 1.9% in both groups in children aged 5 years) and 0% had coma/convulsions. AM, now government-approved in Mali, could be tested as a first-line complement to standard modern drugs in high-transmission areas, in order to reduce the drug pressure for development of resistance to ACT, in the management of malaria. In view of the low rate of severe malaria and good tolerability, AM may also constitute a first-aid treatment when access to other antimalarials is delayed.

Sublingual sugar for hypoglycaemia in children with severe malaria: a pilot clinical study.

BACKGROUND: Hypoglycaemia is a poor prognostic indicator in severe malaria. Intravenous infusions are rarely feasible in rural areas. The efficacy of sublingual sugar (SLS) was assessed in a pilot randomized controlled trial among hypoglycaemic children with severe malaria in Mali. METHODS: Of 151 patients with presumed severe malaria, 23 children with blood glucose concentrations < 60 mg/dl (< 3.3 mmol/l) were assigned randomly to receive either intravenous 10% glucose (IVG; n = 9) or sublingual sugar (SLS; n = 14). In SLS, a teaspoon of sugar, moistened with a few drops of water, was gently placed under the tongue every 20 minutes. The child was put in the recovery position. Blood glucose concentration (BGC) was measured every 5-10 minutes for the first hour. All children were treated for malaria with intramuscular artemether. The primary outcome measure was treatment response, defined as reaching a BGC of >or= 3.3 mmol/l (60 mg/dl) within 40 minutes after admission. Secondary outcome measures were early treatment response at 20 minutes, relapse (early and late), maximal BGC gain (CGmax), and treatment delay. RESULTS: There was no significant difference between the groups in the primary outcome measure. Treatment response occurred in 71% and 67% for SLS and IVG, respectively. Among the responders, relapses occurred in 30% on SLS at 40 minutes and in 17% on IVG at 20 minutes. There was one fatality in each group. Treatment failures in the SLS group were related to children with clenched teeth or swallowing the sugar, whereas in the IVG group, they were due to unavoidable delays in beginning an infusion (median time 17.5 min (range 3-40).Among SLS, the BGC increase was rapid among the nine patients who really kept the sugar sublingually. All but one increased their BGC by 10 minutes with a mean gain of 44 mg/dl (95%CI: 20.5-63.4). CONCLUSION: Sublingual sugar appears to be a child-friendly, well-tolerated and effective promising method of raising blood glucose in severely ill children. More frequent repeated doses are needed to prevent relapse. Children should be monitored for early swallowing which leads to delayed absorption, and in this case another dose of sugar should be given. Sublingual sugar could be proposed as an immediate "first aid" measure while awaiting intravenous glucose. In many cases it may avert the need for intravenous glucose.

Cultural adaptation and application of the IBS-QOL in China: a disease-specific quality-of-life questionnaire.

BACKGROUND: Irritable bowel syndrome (IBS) is a chronic and episodic illness characterized by altered bowel habits and associated abdominal pain. At present, IBS is one of the most common functional gastrointestinal and motility disorders affecting countries around the world. Surveys have found that patients with IBS have a significantly lower health-related quality of life. OBJECTIVES: The aim of this study was to translate and examine the validity of the Irritable Bowel Syndrome-Quality of Life questionnaire (IBS-QOL) in patients suffering from IBS in China. METHODS: A structured procedure was used for the translation and cultural adaptation of the original English IBS-QOL into Chinese. The questionnaire was administered to 73 clinical patients with IBS and 70 healthy individuals. Psychometric testing for reliability, validity and responsiveness followed standardized procedures. Test-retest reliability (10-20 hours) was assessed using the clinical patients. Follow-up (4 weeks) was collected for 61 clinical patients. All enrolled patients also completed the Short Form-36 Health Survey (SF-36) at the baseline visit. Responsiveness to treatment (Venlafaxine and traditional Chinese herbal medicine) was assessed by one-way ANOVA methods. RESULTS: The average length of time required to complete the questionnaire was short (5.63 min for IBS patients and 5.54 min for healthy subjects by self-administration). Internal consistency (Cronbach's alpha) values ranged from 0.722 to 0.914 for the Chinese IBS-QOL subscales and test-retest reliability coefficients were higher than 0.920 on all subscales. The convergent and discriminate validity results comparing the Chinese translation of the IBS-QOL overall score and the SF-36 subscales confirmed our predicted hypotheses. The Chinese IBS-QOL scores are more highly correlated with social functioning, vitality and general health (SF-36) and show weaker associations with physical functioning, role physical, mental health, and bodily pain (SF-36). The Chinese translation of the IBS-QOL was responsive to treatment. CONCLUSION: In general, the Chinese translation of the IBS-QOL, after cultural adaptation and revision, possesses good reliability, validity and responsiveness. It is a reliable and valid instrument to assess the quality of life in Chinese patients suffering from IBS and is an appropriate measure to use in further clinical trials or for related research projects in China.

[Knowledge of traditional healers on malaria in Kendi (Bandiagara) and Finkolo (Sikasso) in Mali ]. / La prise en charge du paludisme par les therapeutes traditionnels dans les aires de sante de Kendie (Bandiagara) et de Finkolo (Sikasso) au Mali.

The survey has been carried out in the context of the project "Traditional Practices and Primary Health Care", developed by the Traditional Medicine Department (DMT) of the INRSP and the Swiss Ngo Antenna Technologies, with the support of Aidemet Ngo. The objective was to evaluate the knowledge, attitudes and practices of traditional healers on uncomplicated and severe malaria, in the perspective of collaboration between traditional and modern medicine for the optimal care of the critical cases. The investigation has been conducted from January to February 2003 in the health areas of Kendié (Bandiagara District, Mopti Region) and Finkolo (Sikasso District and Region). The interviews concerned in total 79 traditional healers, 9 of which were women. The survey showed that the traditional healers have a good knowledge of the symptomatology of uncomplicated and severe malaria, and their diagnosis corresponds with that of the health workers who do not have access to laboratory analyses. On the other hand, the traditional etiology doesn't always correspond with the modern one, even if the traditional healers mention, among the causes of malaria, the mosquito bites. Most treatments were based on plant substances. We identified 66 medicinal species in total. The majority of them had already been studied for anti-plasmodial activity. We therefore investigated 8 of these plants, which had not previously been thoroughly studied. Extracts of different parts of these plants were tested on standard chloroquine-resistant strains of Plasmodium falciparum; the most active plants were Argemone mexicana, Securinega virosa, Spondias mombin and Opilia celtidifolia, with IC50 ranging from 1.00 to 4.01 microg/ml.

Malaria treatment in remote areas of Mali: use of modern and traditional medicines, patient outcome.

Use of official health services often remains low despite great efforts to improve quality of care. Are informal treatments responsible for keeping a number of patients away from standard care, and if so, why? Through a questionnaire survey with proportional cluster samples, we studied the case histories of 952 children in Bandiagara and Sikasso areas of Mali. Most children with reported uncomplicated malaria were first treated at home (87%) with modern medicines alone (40%), a mixture of modern and traditional treatments (33%), or traditional treatment alone (27%). For severe episodes (224 cases), a traditional treatment alone was used in 50% of the cases. Clinical recovery after uncomplicated malaria was above 98% with any type of treatment. For presumed severe malaria, the global mortality rate was 17%; it was not correlated with the type of treatment used (traditional or modern, at home or elsewhere). In the study areas, informal treatments divert a high proportion of patients away from official health services. Patients' experience that outcome after standard therapeutic itineraries is not better than after alternative care may help to explain low use of official health services. We need to study whether some traditional treatments available in remote villages should be considered real, recommendable first aid.
