Introduction: Pakistan has the second highest prevalence of hepatitis C globally. The Musafir study, set up in 2018 in a Parisian suburb to understand the representations of hepatitis and HIV within the Urdu-speaking, male, migrant community living there, provided an opportunity to think about culturally acceptable health promotion interventions. These included awareness campaigns on hepatitis—which did not cover the question of HIV, considered taboo—, held in a mosque.

Background: Social prescription is seen as a public health intervention tool with the potential to mitigate social determinants of health. On one side, social prescription is not yet well developed in France, where social workers usually attend to social needs, and historically, there is a deep divide between the health and social sectors. On the other side, discharge coordination is gaining attention in France as a critical tool to improve the quality of care, assessed indirectly using unplanned rehospitalization rates.

Background: This article is a continuation of the Musafir study published in 2020. Following the results of this study, we designed an educational website with Urdu-speaking volunteers, using a participatory approach. This type of approach aimed at bringing out situated knowledge around taboo/sensitive topics such as sexual and mental health, by considering the cultural, religious, economic, family, and social background of young Urdu-speaking men.

The burden of the first year of the coronavirus disease 2019 (COVID-19) pandemic was greater for vulnerable populations, such as immigrants, people living in disadvantaged urban areas, and people with chronic illnesses whose usual follow-up may have been disrupted. Immigrants receiving care for HIV in Seine-Saint-Denis' hospitals have a combination of such vulnerabilities, while nonimmigrant people living with HIV (PLWHIV) have more heterogeneous vulnerability profiles. The ICOVIH study aimed to compare the socioeconomic effects of the COVID-19 crisis as well as attitudes toward COVID-19 vaccination among immigrant and nonimmigrant PLWHIV.

Although diabetes is common among people living with HIV/AIDS (PLWHA), few data exists on how migrants from Sub-Saharan Africa (SSA) experience living with these two coexisting conditions in France. The objective of this study was to analyze perception of polypathology among PLWHA from SSA with type 2 diabetes and identify barriers and facilitators to their self-management. A qualitative study was conducted using semi-structured interviews from November 2019 to April 2020 with participants selected from a cohort of PLWHA and diabetes at Avicenne University Hospital.

Background: Most publicly-funded health systems purchase healthcare from private providers, but the optimal purchasing arrangements between public purchasers and private healthcare providers are yet to be determined.

Objective: This study compares the healthcare purchasing arrangements made with private providers in 2 social health insurance (SHI)-based systems to identify factors that influence the prices paid for private healthcare service provision.

Results: France and Japan use different approaches to determine the payment arrangements with public and private providers.

According to evidence-based guidelines, vaccines against measles and varicella are generally recommended to susceptible HIV-positive patients, as long as they are not severely immunocompromised. However, routine screening to determine serologic status is not recommended. We conducted a seroprevalence study of anti-measles and anti-Varicella-Zoster virus (VZV) antibodies in adults living with HIV (PLWHA) consulting at Avicenne University Hospital in a Parisian suburb.

Undocumented migrants are a vulnerable population group in the context of the COVID-19 pandemic due to increased risk of infection, severe morbidity, and mortality. In this Personal View, we analyze the COVID-19 pandemic responses, particularly vaccination campaigns, vis à vis undocumented migrants, and discuss lessons learned. Our empirical observations as clinicians and public health practitioners in Italy, Switzerland, France, and the United States are supplemented by a literature review, and presented through country case studies focusing on Governance, Service Delivery, and Information.

Background: The first wave of the COVID-19 pandemic in France was associated with high excess mortality, and anecdotal evidence pointed to differing excess mortality patterns depending on social and environmental determinants. In this study we aimed to investigate the spatial distribution of excess mortality during the first wave of the COVID-19 pandemic in France and relate it at the subnational level to contextual determinants from various dimensions (socioeconomic, population density, overall health status, healthcare access etc.).

Article Synopsis
  • Pre-exposure rabies prophylaxis (PrEP) is essential for those at high risk of exposure to rabies virus, protecting against unrecognized infections.
  • A study of 498 vaccinated individuals revealed that 17.2% showed inadequate immune response after the initial vaccination, while only 0.5% had an inadequate response after receiving a booster dose.
  • The findings suggest that a single booster significantly enhances long-term immunity, potentially simplifying the need for regular antibody monitoring among those at professional risk.

Purpose Of Review: The goal of this paper is to provide an up-to-date review of adverse events related to the class of integrase strand transfer inhibitors (INSTIs), which became the class of choice in few years. We sought answers specifically to issues pertaining to neuropsychiatric adverse events, as well as weight gain, which were the two most important categories of adverse events raised in recent studies based on real-life experience. The primary focus of this paper is on adults with a brief summary on pregnant women and children/adolescents.

Background: Seine-Saint-Denis is a deprived departement (French administrative unit) in the North-East of Paris, France, hosting the majority of South Asian migrants in France. In recent years, the number of migrants from Pakistan, which has a high prevalence of hepatitis C globally, increased. As a corollary, this study addressed the high proportion of Pakistani patients in the infectious diseases clinic of a local hospital, diagnosed with hepatitis C, but also hepatitis B and Human Immunodeficiency Virus (HIV).

Background: France has long been a country of immigration and in some respects may be seen to have a generous policy with respect to asylum seekers and access to health care for migrants. The French state notably provides healthcare access for undocumented migrants, through state medical aid and since 1998 has had a humanitarian policy for granting temporary residence permits for medical reason (TRPMR) to migrants. Within a context of political debate, reform and tightening immigration control we will examine this latter policy focusing especially on the dilemmas that arise for physicians of migrant patients when they are requested to write medical certificates as part of a TRPMR application.

Background: This study sought to determine the proportion of individuals with non-HIV secondary immunodeficiencies presenting inadequate antibody titers after rabies post-exposure prophylaxis (PEP) and to identify variables associated with inadequate response.

Methods: A retrospective review of the records of immunocompromised patients having received a full course of PEP after a rabies exposure and having been tested for post-PPE antibody titers in two French Antirabies Clinics, between 2013 and 2018, was conducted. Antibody titers < 0.

Drawing on hospital-based interviews and fieldwork in a deprived Parisian suburb, this paper analyses the spatio-temporal dynamics of risk, exposure, and mobilities in individual stories of undocumented Pakistani male migrants, and asylum seekers-receiving treatment for single and combined diagnoses of HIV, and Hepatitis C and B. Inviting alignments with the 'sexual' turn in mobility studies, it prioritises the interface of all-male undocumented migration, mobility, sexuality, and homosociality in circumscribing disease transmission geneaologies. It questions the extent to which illegal migration routes are transmission routes, and risk environments assume different levels of intensity in everyday life in Pakistan, during the journey, and in France.

Background: Imported loiasis is a rare cause of consultation at the return of stay in central Africa, which often poses difficult diagnostic and therapeutic questions to practitioners especially those who are unaccustomed to tropical medicine. These difficulties can lead to risks for the patients especially if inappropriate treatment is given. Large series of imported loiasis are scarce.

This paper introduces few concepts to help clinicians to get an idea of the health systems of the migrants they care for, on a daily basis. Health systems are complex to analyze, and is an open, dynamic system, facing diverse influences from multiple levels. Recent globalization has complexified an already complex system.

Migrant populations, due to their condition of migrants, are exposed to structural vulnerability factors, which influence their health status. Globally, evidences on the negative impact of these structural factors on migrants' health are increasing. We hereby describe these structural factors, which exert their influence at health system's macro-, meso- and micro-levels.

Background: The launch of Global Health Initiatives in early 2000' coincided with the end of the war in Burundi. The first large amount of funding the country received was ear-marked for human immunodeficiency virus (HIV) and immunization programs. Thereafter, when at global level aid effectiveness increasingly gained attention, coordination mechanisms started to be implemented at national level.
