FRI0447 FIRST COMPREHENSIVE LONG-TERM ASSESSMENT OF MUSCULOSKELETAL CONSEQUENCES AMONG EBOLA SURVIVORS

Background:

The tremendous size of the 2013-2016 West African outbreak of Ebola virus disease (EVD) resulted in a sizeable population of survivors, many reporting short-term sequelae such as arthralgia and myalgia.

Objectives:

We aimed to report a detailed and long-term description of patients’ musculoskeletal (MS) symptoms.

Methods:

We performed a cross-sectional study following systematic rheumatological screening of patients included in the Postebogui cohort (Conakry district). We used regression models to establish the magnitude of EVD as a risk factor for developing chronic MS pain by comparison with a control cohort and to establish risk factors for developing MS pain among survivors.

Results:

The study included 313 patients (55.6% female), with a median age of 28.2 years (IQR 21-37), and a median time from ETC discharge to rheumatological visit of 26.2 months (IQR 23-30). Chronic MS pain was reported in 216 (69%) patients, and was predominantly mechanical (48%). Enthesis and painful peripheral joints were largely involved (91%) with symmetrical distribution. Previous Ebola infection was a major risk factor for chronic MS pain (aOR, 6.662 [95% CI, 4.522–9.921]). Among survivors, increasing age (OR 1.14, 95% CI 1.08-1.22) and female gender (OR 3.58, 95% CI 1.22-11.80) were both associated with persistent MS pain, while myalgia experienced during the acute phase of EVD appeared protective (OR 0.14, 95% CI 0.04-0.42).

Conclusion:

Our study provides the most accurate long-term description of MS disorders among Ebola survivors. Joint and muscle pain sequelae are frequent and require specialized care.

[Representations of therapeutic failure of ARV treatment among patients and health care professionals in Dakar]

The aim of this qualitative study was to describe and analyze representations of therapeutic failure and the medical and social responses proposed by health care professionals and patients receiving follow-up in the ANRS cohort 1215 in Senegal from 1999 to 2010. Patients' medical histories show that therapeutic failures are related to complex multifactorial situations, resulting from factors attributable to patients (adherence failure related to various psychosocial problems) but also to health care structures (organization of the health system, training for health care professionals and availability of biological exams and appropriate drugs). Both patients and health care staff recognize these causes. The incidence of the onset of therapeutic failures should be regarded as an indicator of the quality of care provided. Further thought should be given to how well health care systems function when changes occur in these rates.

Twelve years of follow-up for patients treated with ARVs in Senegal (ANRS Cohort 1215): description of population and methodology

The ANRS Cohort 1215 brought together the first 400 patients receiving antiretroviral treatments through the government program for ARV treatment in Senegal. These people, infected with HIV-1, began their treatment between 1998 and 2002; they were treated with 2 NRTI + 1 PI or NNRTI. This prospective observational cohort received follow-up over the course of 12 years, from 1999 to 2010, and was one of the earliest established cohorts in Africa and providing the longest duration of ART follow-up. A series of interdisciplinary studies was conducted among these patients to assess the medical and social as well as the individual and collective impact of these treatments over the long term. This article presents the cohort's key methodological characteristics.

[The social relegation of widows living with HIV in the time of ART in Senegal]

While prolonged widowhood is unusual in Senegalese society, some women living with HIV receiving antiretroviral therapy for ten years remained widows. Are they maintained in this situation for refusing or being unable to remarry? To understand the conditions and the reasons for this lack of "matrimonial normalization", a qualitative interview study was conducted in Dakar with 31 widows. Their living conditions are mostly marked by economic difficulties, dependence on host families, and responsibilities visà-vis their children. They refuse to remarry, regret not being able to, or wish to without success, despite the existence locally of social forms of marital union that would respond to their situation. The refusal to disclose their HIV status combined with self-stigma prevent them from improving their condition. This form of social vulnerability that remains beyond the restoration of health is ignored by public policy and HIV/AIDS community based organizations claims. It should be acknowledged and considered for defending PLWAs' rights.

[Late diagnosis of HIV infection in the Fann, Dakar clinic of infectious diseases: testing circumstances, therapeutic course of patients, and determining factors]

BACKGROUND AND METHODOLOGY

The delay in the diagnosis of HIV infection is a major obstacle to optimal care for this disease. To deal with this problem, we conducted this study among newly diagnosed HIV patients hospitalized in the Fann University Hospital Infectious Diseases Clinic in Dakar. The epidemiological, clinical, biological and outcome aspects are described and patient history reviewed. A qualitative socio-anthropological study was made to understand and describe the logic of the decision processes in the patient's search for treatment.

RESULTS

One hundred patients were included, with a mean age of 39.5+/-11.1 years and a sex-ratio: 1.08. The transmission was mainly heterosexual (90%), and chronic diarrhea (64%) and/or chronic cough (66%) were the principal symptoms leading to diagnosis. The mean delay before diagnosis was 5+/-4.27 months. The major opportunistic diseases were tuberculosis (44 cases) and infectious diarrhea (23 cases). Most patients were diagnosed at the AIDS stage (97%) and the death rate was 30% among hospitalized patients after admission. Sixty-eight percent of patients had consulted at least three times, generally a "traditional practitioner", at first and 43% had been hospitalized at least once. The qualitative investigation revealed that the "representation" or the "feeling of severity" of the disease were the principal justifications for consulting the "traditional practitioner" or the physician, respectively.

CONCLUSION

Better information for health workers and global population is necessary for an earlier diagnosis of HIV infection in Dakar.

Grossesse sous efavirenz (Sustiva®) : à propos de 12 cas de patientes positives pour le VIH

OBJECTIVE

In developed countries, where the mother-to-child transmission rate of HIV is low (1 to 1,5%), a major medical concern is the safety of new therapies during pregnancy. Teratogenicity has been described with an NNRTI, efavirenz (Sustiva), in animal model, regarding neural tube defects.

PATIENTS AND METHODS

We have made a retrospective study of pregnancies starting with efavirenz with a special focus on foetal and infant abnormalities.

RESULTS

Three abnormalities were notified no one linked to a neural tube defect.

DISCUSSION AND CONCLUSION

In the English literature published, although the prevalence of abnormalities in human is low (1,7%) during pregnancy, due to the potent teratogenicity, efavirenz is contraindicated in the first trimester and should be used with caution in women of childbearing potential.

Impact of Newly Available Drugs on Clinical Progression in Patients with Virological Failure after Exposure to Three Classes of Antiretrovirals

Objective

To study the prognosis of HIV-infected patients with virological failure after exposure to three classes of antiretroviral drugs (ARVs).

Design

Cohort study. Setting: French Hospital Database on HIV.

Patients

Patients previously exposed to at least two nucleoside reverse transcriptase inhibitors (NRTIs), two protease inhibitors and one non-NRTI, with viral load (VL) values of >5000 copies/ml after the exposure criteria were met and a new treatment initiated between 1998 and 2001 with VL >5000 copies/ml.

Main outcome measures

Risk of new AIDS-defining-events (ADEs) or death from first introduction of a drug never used before occurring between 1998 and 2001 defined as baseline.

Results

The main baseline characteristics of the 1092 patients were: previous ADE in 49% of cases, median CD4 cell count 181 μl, median VL 4.9 log10 copies/ml, median duration of ARV therapy 5.0 years and previous exposure to a median of nine ARVs. The crude progression rates were 20.1/100 patient-years among patients included in 1998, 15.1 in 1999, 11.1 in 2000 and 8.6 in 2001. After adjustment for baseline characteristics, the calendar year of inclusion was associated with the risk of clinical progression ( P<0.001). When the types of newly available drugs used at baseline or during follow-up were introduced into the model, year of inclusion was no longer associated with the risk of clinical progression ( P=0.42), while exposure to amprenavir/r, lopinavir/r, abacavir or tenofovir was associated with a lower risk.

Conclusions

The clinical prognosis of heavily pretreated patients experiencing virological failure improved between 1998 and 2001, mainly thanks to the use of newly available drugs with more favourable resistance profiles.

[Free dispensing of antiretroviral treatments in Africa]

The bio-clinical efficacy of ART in Africa has now been proven. In 2001, the resolution adopted by the UNGASS meeting confirms that "effective prevention, care and treatment strategies will require [...] a non-discriminatory access to [...] anti-retroviral therapies". Most of the programmes that give access to ART initiated in the sub-Saharan region in 1998 are based on the principle that the patients participate financially to the purchases of ART. Some countries (Côte d'Ivoire, Senegal, and Mali) subsidize ART medications to favour a better access. The financial contribution of patients is supposed to: 1/ translate patient support into government action; 2/ favour a closer therapeutic adherence; 3/ assure the access programmes sustainability. However, despite the subsidies provided by some states, the cost of medical treatment greatly exceeds the resources available to most of the sufferers. The analysis of ART access programmes, specifically in Senegal and Côte d'Ivoire, shows that: 1/ Patient support to government action does not need to be more demonstrated while general access to treatment is officially recognised and recommended by the United Nations. 2/ Patient involvement and better adherence have been noted with patients that receive free ART. 3/ Patient contribution represents less than 10% of the medication's purchasing cost, thus, the cost recovery is marginal and does not allow for sustainable ART access programmes. The cost charged to patients for ARV still represents a major obstacle for proper medical management. Care programmes in African countries should implement free access to ART as a priority.

[Representations of mother to child transmission of AIDS, perception of the risk and health information messages in Burkina Faso]

In Burkina Faso, in rural Mossi areas, popular contemporary representations of the transmission of HIV from mother to child are based on the idea that "the disease is in the blood" and that the fetus is conceived by "mixing the blood" of its parents. Infection of the child is seen as inevitable and systematic and is believed to occur in utero. Maternal milk is thought to have the same potential for infection because "milk is blood" but its role in transmission is seen as secondary, with transmission occurring before birth. However, breast feeding is believed to be responsible for the transmission of the disease in two ways: 1) by infected women transmitting the illness to healthy children via their milk and 2) by healthy women becoming infected by breast feeding infants born to infected mothers. The belief that transmission is systematic and the fear that the child will contaminate others leads to the widely held view within the population that no care should be taken of children born to women with AIDS and that such children should be abandoned and left to die. These representations have recently developed in the population based on preexisting beliefs relating to the physiology and role of blood in the transmission of diseases and the health information that has been distributed. Health information messages are largely responsible for the representations described above. Indeed, the description of the modes of HIV transmission in such messages has been based on the simplified statement of the triad, sex, blood and mother-child, with no indication of the relative risks of transmission for each. Hence, this incomplete information, interpreted in terms of popular conceptions about contagion, has resulted in maximal probability being attributed to each of the listed modes of transmission. Health information messages are the principal means of communicating scientific information to the general population. The stakes associated with the quality and correctness of the information supplied are therefore very high. The notion of the risk of transmission and statement of the level of risk are essential to any explanation of the modes of transmission of HIV. These ideas cannot be neglected because they are essential to the correct understanding of transmission and to the logical management of individual risk.

[How to manage HIV seropositive or AIDS patients in rural Burkina Faso?]

This article is based on an ethnographical study carried out in 1996. It describes and analyzes the methods of medical and family management of HIV-positive and full-blown AIDS patients in the rural environment of Burkinabé. A number of recommendations are made. Biomedical management of these patients is almost non-existent (currently there is no serology or screening advice available at the dispensary). The patient is never informed of an AIDS diagnosis. The relations between the medical personnel and the patients are dominated by a sense of powerlessness and constant fear of infection. None of the traditional doctors of the region admits to treating AIDS although traditional medicine is used throughout the illness. Family management ranges from complete rejection of the patient to supportive but often misdirected care. It is determined by at least five elements: (1) the composition of the family unit and the nature of relations between the sick individual and the rest of the family, (2) the economic status of the patients, his family group and his parents, (3) the initial uncertainties of the diagnosis of the illness, (4) the fear of contagion and (5) the fear of gossip. Management of these patients would be improved by: (1) real access to counseling and screening, (2) the involvement of health workers in this activity and in the notification of the diagnosis to the peripheral medical organizations, (3) the education of the staff about the risks of contamination and care of the terminally ill, (4) reeducation of the public about the non-contagious nature of the sick by personal counseling given by health care professionals and (5) the material support of families. This is of vital importance but is difficult to achieve in the context of chronic poverty.
