Brief Summary:

Chikungunya virus (CHIKV) has been detected in humans in the Caribbean area for the first time in November 2013 (St-Martin Island). By February 2014, the virus had spread to several other Caribbean islands as well as French Guyana, South America. During the outbreak of Chikungunya that affected the Reunion island in 2005/2006, it was observed that the neonatal forms of infections acquired by mother to child transmission during childbirth, were not the exception and were critical. Mother-to-child transmission occurs when the mother is viremic at the time of delivery. The mean duration of viremia after the onset of first clinical symptoms is six days. The rate of mother-to-child transmission is 50%. All neonates contaminated during labor and delivery present with a symptomatic disease and the rate of severe forms is about 50%, primarily due to damage of the central nervous system, often leaving permanent damage (seizures, cerebral palsy).Due to the severity of Chikungunya in neonates and the burden of cerebral palsy, it is imperative to identify a safe and effective preventive and/or curative intervention. Human polyvalent immunoglobulins purified from plasma samples obtained from Chikungunya-convalescent donors exhibit a potent neutralizing activity in vitro. They were evaluated for their preventive and curative effects in a neonatal mouse model of CHIKV infection. After administration of a lethal dose of CHIKV, all neonatal mice that had received immunoglobulins survived while all control animals that had received non hyperimmune immunoglobulins died. In humans, specific human immunoglobulins proved to be effective and safe in neonates born to hepatitis B viremic mothers.

Hypothesis : The investigators hypothesize that the administration of anti-CHIKV hyperimmune human intravenous immunoglobulins to neonates exposed to a high risk of severe form of Chikungunya infection is safe enough to justify its evaluation in an open non randomized trial aimed to confirm the safety and preliminary assess the efficacy of this intervention.

Intervention Details:
  • Biological: anti-CHIKV hyperimmune immunoglobulins
    Anti-CHIKV immunoglobulins (CHIKVIg) were purified after the Tégéline manufacturing process from a pool of 583 plasma samples from donors in the convalescent phase of CHIKV infections. Anti-CHIKV hyper immune intravenous immunoglobulin (50 mg/ml) is prepared as a powder to be reconstituted. The therapeutic regimen will consist of 2 doses of 0.5 g/kg 12 hours apart.

Primary Outcome Measures :
  1. Safety [ Time Frame: 30 days ]

    The primary endpoint will measure tolerability and safety of anti-CHIKV hyperimmune IVIG. It will be evaluated in all enrolled neonates and will be based on the occurrence of the following events:

    • patent ductus arteriosus,
    • ulceronecrotizing enterocolitis,
    • pulmonary hemorrhage,
    • tachycardia, hypotension, decreased O2 saturation during anti-CHIKV IVIG infusion,
    • hemolytic anemia,
    • fluid overload, as indicated by hyponatremia and/or ascites.

Secondary Outcome Measures :
  1. Efficacy [ Time Frame: 30 days ]

    The following secondary endpoints will be evaluated only in neonates born to mothers who had a definite CHIKV-infection.

    Neonates will be classified in one of the following 3 categories:

    • Neonatal CHIKV clinical disease:

      • Clinical symptoms consistent with acute CHIKV infection
      • Demonstration of infection based on CHIKV IgM seroconversion and/or identification of CHIKV viremia (positive CHIKV qRT-PCR at Day 3),
    • Neonatal CHIKV asymptomatic infection:

      • Absence of any symptom consistent with CHIV infection
      • Demonstration of infection based on CHIKV IgM seroconversion and/or identification of CHIKV viremia (positive CHIKV qRT-PCR at Day 3),
    • Neonatal CHIKV infection excluded:

      • Absence of CHIKV IgM seroconversion.

    Below is an indicative list of symptoms that are consistent with Chikungunya infection in neonates:

    • Skin rash, severe desquamative disorder, bullous dermatitis,
    • Acral edema
    • Symptoms of encephalopathy/encephalitis : stupor, seizures, impaired sucking
