Parasitemia: Causes & Reasons

Possible Causes for Parasitemia

[…] accuracy plus the known advantages of AO/FM suggest that the test, supplemented with G-TS to improve species and stage differentiation, is also useful for screening low-density parasitemias [ncbi.nlm.nih.gov]

The following day, parasitemia increased to 7.9% and oral AL was initiated. She was discharged on day 4 after achieving parasite clearance and afebrility. [ncbi.nlm.nih.gov]

As having a high parasitemia rate (20.6%) was the only severe malaria criterion met in this case and his general condition was stable, we continued with AL treatment. [ncbi.nlm.nih.gov]

Plasmodium Falciparum Malaria

Most clinicians in developed countries have limited experience in making clinical assessments of malaria disease severity and/or monitoring high-level parasitemia in febrile [ncbi.nlm.nih.gov]

The diagnosis relied on blood smear which showed a parasitemia <0.2% in three cases. [ncbi.nlm.nih.gov]

On admission, a thick blood smear revealed severe Plasmodium falciparum parasitemia. [ncbi.nlm.nih.gov]

Cerebral Malaria

A lower bound for the fraction of retinopathy-negative CM that would be prevented if malaria parasitemia were to be eliminated is estimated to be 0.93 (95% confidence interval [ncbi.nlm.nih.gov]

RBC exchange transfusion can reduce the level of parasitemia in this setting. [ncbi.nlm.nih.gov]

Her hemoglobin decreased from 12.6 to 6.5 g/dL with 12% intraerythrocytic parasitemia by thin smear. [ncbi.nlm.nih.gov]

Plasmodium Vivax Malaria

Parasitemia is clearly related to progression and severity of malaria caused by P. falciparum, however the effects of parasitemia during infections with P. vivax are not well [ncbi.nlm.nih.gov]

Furthermore, the TLR9 variant -1237C/C correlates with high parasitemia. [ncbi.nlm.nih.gov]

Similar studies in 70 patients in the same area in 2007 showed no recurrent parasitemias within 28 days. [ncbi.nlm.nih.gov]

Exchange Transfusion

RBC exchange transfusion can reduce the level of parasitemia in this setting. [ncbi.nlm.nih.gov]

The degree of mortality and morbidity usually corresponds to the degree of parasitemia. [ncbi.nlm.nih.gov]

This resulted in a decreased parasitemia and clinical improvement. The patient underwent a cesarean section, and a healthy child was delivered. [ncbi.nlm.nih.gov]

Blackwater Fever

Low-level P. falciparum parasitemia was found in 8 patients. All 21 patients survived. [ncbi.nlm.nih.gov]

Parasitemia is mild or absent. The mechanism of renal failure is tubular necrosis. [ncbi.nlm.nih.gov]

It is unlikely that the emergency physician will know the patient’s degree of parasitemia. [emedicine.medscape.com]

Chagas Disease

Two different doses of IL-2 (1,500 or 10,000 U) given at 3 different times during infection were equivalent in reducing parasitemia. [ncbi.nlm.nih.gov]

Two different doses of IL‐2 (1,500 or 10,000 U) given at 3 different times during infection were equivalent in reducing parasitemia. [doi.org]

We conclude that pregnancy enhances the parasitemia in Chagas disease, with a higher effect early in pregnancy. [ncbi.nlm.nih.gov]

Acute Chagas Disease with Myocarditis

HIV/ T. cruzi -coinfected person often develop bizarre neurological lesions or acute myocarditis in the context of high-level parasitemia. [med.unc.edu]

Immunosuppression may reactivate latent infection, with high parasitemia and a 2nd acute stage, skin lesions, or brain abscesses. [merckmanuals.com]

[…] experience sudden cardiac death Digestive system complications Megacolon Ranges from mild achalasia to megaesophagus Congenital disease Highest risk for infection when maternal parasitemia [arupconsult.com]

Babesiosis

Babesia frequently are overlooked, however, because parasitemia tends to be sparse, often infecting fewer than 1% of erythrocytes early in the course of the illness. [ncbi.nlm.nih.gov]

The mean peak parasitemia was 7.6% (median, 15.1%; range, 0.1%–30%; figure 2 ). [academic.oup.com]

Exchange transfusion is a potentially life-saving therapy for patients suffering from severe disease with high parasitemia (>5%), significant hemolysis, or renal or pulmonary [ncbi.nlm.nih.gov]

Hemoglobin C Disease

Initial parasitemias were 0.1%. Parasite densities were counted daily. [doi.org]

Parasitemias (mean ± SD) were calculated from triplicate counts of 1000 RBCs. [doi.org]

Initial parasitemias were 0.1%. Parasite densities were counted after 3 and 4 days of culture. [doi.org]

West African Trypanosomiasis

The CSF should be examined even if parasitemia is confirmed. [antiinfectivemeds.com]

These are more likely to be positive in early infection when parasitemia precominates and in T. b. rhodesiense infection, which has higher levels of parasitemia overall. [infectiousdiseaseadvisor.com]

One to three weeks after the infection, the actual parasitemia sets in, accompanied by fever, ague, pain in the head and limbs, edema, itching, exanthem and swelling of the [flexikon.doccheck.com]

Chronic Malaria

“Asymptomatic” malaria and placental parasitemia also have major consequences for mothers and their newborns. [journals.plos.org]

Marked splenomegaly can occur even in low-grade parasitemia (50/ml) and it may persist for weeks or months after effective and complete treatment. [malariasite.com]

Ergotamine Withdrawal

One was an overwhelming infection; any patient with an intense parasitemia (400,000 parasites/mm3) was in danger of developing a major complication. [annals.org]

In addition, molecular tests such as PCR can detect parasites in specimens where the parasitemia may be below the detectable level of blood film examination. [cdc.gov]

P falciparum is able to infect RBCs of all ages, resulting in high levels of parasitemia (>5% RBCs infected). [medscape.com]

Loa Loa Filaria

Despite negative parasitemia, we decided to treat with diethylcarbamazine (DEC) for 21 days. [ncbi.nlm.nih.gov]

If parasitemia is found to be greater than 8000 microfilaria per mL, no antiparasitic agent should be used until apheresis can be used to decrease the parasitemia. [emedicine.medscape.com]

Since the levels of parasitemia may fluctuate, multiple smears may be needed to detect the filarial worms. [mayomedicallaboratories.com]

Protozoan Infection

Alternatively, blood may be injected into a laboratory rodent, whose blood is then monitored for evidence of parasitemia. [what-when-how.com]

The recurrent cycles of parasitemia and antibody production continue until the patient is treated or dies. [alpfmedical.info]

Nifurtimox (available from the CDC Drug Service) eliminates parasitemia [see Sidebar, Protozoan Infection Information on the Internet]. [what-when-how.com]

Congenital Malaria

The prevalence rate of maternal parasitemia was 15% overall and varied from 4% to 30% at the different sites. [journals.sagepub.com]

In the subsequent 4 hours, parasitemia steadily declined. [ncbi.nlm.nih.gov]

Those with asymptomatic parasitemia at birth may either suppress this spontaneously, or present with clinical symptoms in the late neonatal period [5]. [ncbi.nlm.nih.gov]

Babesia

No previous report has shown such a rapid rebound in parasitemia despite adequate organism removal. [ncbi.nlm.nih.gov]

In the absence of therapy, however, Bab. microti parasitemia may persist for more than two years. 7 In clinical practice, the duration of parasitemia may be difficult to monitor [content.nejm.org]

His post-procedural course was significant for diminishing periodic increases in parasitemia despite continued antimicrobial therapy. [ncbi.nlm.nih.gov]

Babesia Microti

More than half of seropositive donors tested had demonstrable parasitemia, indicating that many are at risk for transmitting B. microti by blood transfusion. [ncbi.nlm.nih.gov]

Three of nine persons who had more than one specimen with evidence of parasitemia had nonconsecutive positives. [ncbi.nlm.nih.gov]

Factors that may have allowed the patient to sustain such high-level parasitemia are considered. [ncbi.nlm.nih.gov]
