Eighteen day old neonate presented with features of early neonatal sepsis. History of mother revealed a travel from non-endemic area of malaria to endemic area, and on the 7th gestational age mother detected as having malaria. She was treated with quinine and cured. Baby was also evaluated for congenital malaria in first few neonatal days and discharged. Now the baby on evaluation shows anemia, hepatosplenomegaly and diagnosed with a Plasmodium vivax infection on peripheral smear. The quinine failed to prevent transplacental transmission. Prolonged interval between birth and onset of symptoms may be explained by transmission late in pregnancy or during delivery or by presence of transplacentally acquired maternal antibody (IgG). Mother acquired malarial infection after travel to an endemic area and transmitted to the baby. A high level of suspicion is warranted in babies of malaria infected mothers even when the neonate peripheral smear shows no evidence of infection.

Hemophagocytic lymphohistiocytosis (HLH) is an unusual syndrome characterized by fever, hepatosplenomegaly, cytopenias, hypertriglyceridemia, hypofibrinogenemia, and pathologic findings of hemophagocytosis in the bone marrow and other tissues. HLH may be familial or associated with different types of infections, autoimmune disorders, or malignancies. Infection-associated HLH has been reported in various viral, bacterial, fungal, and parasitic infections, and case reports of parasitic infections implicated in HLH include rare cases from Plasmodium vivax infection, which occasionally affects both military personnel and civilians in Korea. We describe an unusual case of HLH resulting from Plasmodium vivax infection and review the literature. This case suggests that clinical suspicion of HLH is important when P. vivax infection is accompanied by cytopenias. Administration of antimalarial drugs may prevent irreversible end organ damage resulting from P. vivax-associated HLH.

A 4-year-old boy from the United States had been staying in Indonesia for five months when he presented with fever, severe lethargy, progressive weight loss, and abdominal distension. He was first diagnosed with Plasmodium vivax infection in Indonesia and received treatment with chloroquine. However, his condition continued to deteriorate and he required erythrocyte transfusion for severe anemia. Three weeks into his illness, he was found to have low parasitemia with Plasmodium falciparum with massive hepatosplenomegaly in Singapore. A splenic infarct was also documented on computed tomography. Treatment with atovaquone-proguanil resulted in stabilization of the hemoglobin level and rapid reduction in splenic size, with clearance of malarial parasites from the bloodstream. Although reported typically in adult tropical residents, hyper-reactive malarial splenomegaly may occasionally be found in the pediatric traveler. Clinicians receiving children returning from the tropical regions should be aware of this potentially life-threatening complication of partially treated malaria.

Haemophagocytic lymphohistiocytosis (HLH) is a potentially fatal syndrome that is caused by an abnormal activation of the immune system. It can present as the primary syndrome or occur secondary to a variety of conditions such as malignancy, autoimmune diseases and infections. We present a case of a man who developed HLH secondary to Plasmodium vivax infection. He presented with symptoms of fever, chills and myalgias. Physical examination revealed significant hepatosplenomegaly. The presence of pancytopaenia, elevated ferritin levels and haemophagocytosis on bone marrow biopsy confirmed the diagnosis of HLH (based on HLH-2004 criteria). There was a significant improvement after the initiation of intravenous antimalarials. No relapses were documented on follow-up. It is imperative that physicians should promptly recognise and treat this rare condition, as a timely intervention can be lifesaving.

Both malaria and relapsing fever Borrelia are infectious diseases characterized by fever, headache, myalgia, hepatosplenomegaly and tendency to relapse. Exflagellation of microgametocyte in malarial parasites is seen only in the definitive host, i.e., mosquitoes. Here we report an unusual case of a 23-year-old man who presented Plasmodium vivax infection with multiple exflagellated microgametes in the peripheral blood smear.
