recurrence malaria quinine

Radical cure of Plasmodium vivax infection applies blood schizontocidal therapy against the acute attack and hypnozoitocidal therapy against later relapse. Chloroquine and primaquine have been used for 60 years in this manner. Resistance to chloroquine by the parasite now requires partnering other blood schizontocides with primaquine. However, the safety and efficacy of primaquine against relapse when combined with other drugs have not been demonstrated. This randomized, open-label, and relapse-controlled trial estimated the efficacy of primaquine against relapse when administered with quinine or dihydroartemisinin-piperaquine for treatment of the acute infection...

Intravenous (i.v.) artesunate is now the recommended first-line treatment of severe falciparum malaria in adults and children by WHO guidelines. Nevertheless, several cases of haemolytic anaemia due to i.v. artesunate treatment have been reported. This paper describes the case of an HIV-infected patient with severe falciparum malaria who was diagnosed with haemolytic anaemia after treatment with oral artemether-lumefantrine.The patient presented with fever, headache, and arthromyalgia after returning from Central African Republic where he had been working...

Quartan malaria due to Plasmodium malariae is commonly regarded as being preventable by current antimalarials. A case of P. malariae infection occurred in spite of previous treatment of Plasmodium falciparum malaria 4 months earlier with a full therapy course of intravenous quinine hydrochloride and oral doxycycline followed by artemether + lumefantrine. Since the patient was not anymore exposed to agents of malaria in the meantime, a new infection by P. malariae after therapy is unlikely. The present observation is difficult to explain by the current view on the origin of latent P...

BACKGROUND: Increasing rates of failure of artemisinin-based combination therapy have highlighted the possibility of emerging artemisinin resistance along the Thai-Cambodian border. We used an integrated in vivo-in vitro approach to assess the presence of artemisinin resistance in western Cambodia. This article provides additional data from a clinical trial that has been published in The New England Journal of Medicine. METHODS: Ninety-four adult patients from Battambang Province, western Cambodia, who presented with uncomplicated falciparum malaria were randomized to receive high-dose artesunate therapy (4 mg/kg/day orally for 7 days) or quinine-tetracycline...

BACKGROUND: The emergence of drug resistance is a major problem in malaria control. Combination of molecular genotyping and characterization of mutations or single nucleotide polymorphisms (SNPs) correlated with drug resistance can provide information for subsequent surveillance of existing and developing drug resistance patterns. The introduction of artemether/lumefantrine (AL) as first-line treatment, never used before in Ethiopia, allowed the collection of baseline data of molecular polymorphisms before a selection due to AL could occur...

BACKGROUND: Applying the switch from presumptive treatment of malaria to new policies of anti-malarial prescriptions restricted to parasitologically-confirmed cases is a still unsolved challenge. Pragmatic studies can provide data on consequences of such a switch. In order to assess whether restricting anti-malarials to rapid diagnostic test (RDT)-confirmed cases in children of between five and 15 years of age is consistent with an adequate management of fevers, a school-based study was performed in Allada, Benin...

BACKGROUND: Babesiosis is an emerging tickborne malaria-like infection principally caused by Babesia microti. This infection typically resolves either spontaneously or after administration of a 7-10-day course of azithromycin plus atovaquone or clindamycin plus quinine. Although certain highly immunocompromised patients may respond suboptimally to these drug regimens, unlike the situation with malaria there has been no reported evidence that the cause of treatment failure is infection with drug-resistant strains of B...

Symptoms revealing a state of consciousness, attributable to incoördination of afferent impulses connected with the vestibular system-disturbances of muscle-sense-vestibular ocular tracks-vestibular-spinal tracks. DIFFERENT VERTIGO-COMPLEXES.: Destructive lesions of labyrinth, or of vestibular tracks, partial or complete.-Heterogeneous stimulations of the paired intact vestibular-end organs.-The hypersensitive labyrinth.-Clinical manifestations of vertigo, associated with nausea, headache, visual disturbances, nystagmus, diplopia, staggering gait, vasomotor and cardio-vascular symptoms, pallor, flushing, sweating, dyspnoea, fainting, vomiting and diarrhoea...

BACKGROUND: The time necessary for malaria parasite to re-appear in the blood following treatment (re-infection time) is an indirect method for evaluating the immune defences operating against pre-erythrocytic and early erythrocytic malaria stages. Few longitudinal data are available in populations in whom malaria transmission level had also been measured. METHODS: One hundred and ten individuals from the village of Ndiop (Senegal), aged between one and 72 years, were cured of malaria by quinine (25 mg/day oral Quinimax in three equal daily doses, for seven days)...

Several African countries that have adopted artemisinin-based combination therapy (ACT) as first-line treatment of uncomplicated Plasmodium falciparum malaria also use quinine monotherapy as second-line therapy. This policy goes against WHO recommendations for combination therapy and could be considered an inappropriate public health policy. Adherence to a 7-day quinine treatment schedule is likely to be poor and may increase the risk of selecting resistant parasites. Furthermore, because quinine has limited post-treatment prophylaxis, it will not prevent, in areas of intense transmission, recurrent malaria infections, which can lead to additional morbidity, including anaemia...

A 29-year-old patient who was born in Angola developed Plasmodium falciparum malaria 8 years after leaving Africa. She had not returned to a malaria-endemic area, and there were no apparent risks of local or nosocomial acquisition of malaria in Canada. She recovered after treatment with oral quinine sulfate and doxycycline.

Between 1885 and 1892--a period in which great advances have been made in techniques and practice of the young science of microbiology--Camillo Golgi provided a notable contribution to malariology. Continuing studies and researches of Roman malariologists Ettore Marchiafava (1847-1935) and Angelo Celli (1857-1914), on the malarial parasites--described by the French military physician Alphonse Laveran--he studied the reproduction cycles of the Plasmodium in human blood (Golgi cycles) and elucidated the temporal coincidence between the recurrent chills and fever with the rupture and release of merozoites into the blood stream (Golgi law)...

Dihydroartemisinin-piperaquine (DHA-PPQ) is a promising new artemisinin combination treatment. There are no published data on the intentional use of the drug in pregnancy. Between June 2006 and January 2007, 50 Karen pregnant women with recurrent P. falciparum infections, despite 7-day treatments with quinine or artesunate (+/-clindamycin) or both, were treated with DHA-PPQ. This rescue treatment was effective and well tolerated and there was no evidence of toxicity for the mothers or the fetus. The PCR adjusted cure rate by Kaplan Meier analysis at day 63 was 92...

BACKGROUND: Human babesiosis is a tickborne malaria-like illness that generally resolves without complication after administration of atovaquone and azithromycin or clindamycin and quinine. Although patients experiencing babesiosis that is unresponsive to standard antimicrobial therapy have been described, the pathogenesis, clinical course, and optimal treatment regimen of such cases remain uncertain. METHODS: We compared the immunologic status, clinical course, and treatment of 14 case patients who experienced morbidity or death after persistence of Babesia microti infection, despite repeated courses of antibabesial treatment, with those of 46 control subjects whose infection resolved after a single course of standard therapy...

OBJECTIVE: To describe the outcome of 21 successive patients with falciparum malaria treated with artemether-lumefantrine in 6 oral doses of 80-480 mg in 96 hrs (5-day schedule). DESIGN: Retrospective cohort study. METHOD: The data on all successive patients with falciparum malaria that were treated with artemether-lumefantrine in the Leiden University Medical Centre (n = 15) and the Bronovo Hospital (n = 6), the Netherlands, during the period from August 2003 to February 2006 were evaluated...

Pulmonary edema is a recognized complication of Plasmodium falciparum malaria but is uncommon with Plasmodium vivax infection. We report the case of a non-immune adult with imported P. vivax malaria who developed pulmonary edema during treatment. The case was further complicated by a recurrent malaria episode after failure of acute quinine and doxycycline treatment followed by terminal primaquine therapy. Prompt recognition and appropriate management of pulmonary edema is needed for optimal outcomes of P. vivax infection, as well as awareness of the potential failure of terminal therapy for liver hypnozoites...

Incidence of severe imported malaria increases with the multiplication of humanitarian and military missions in malarial endemic areas. The purpose of this study was to describe the demographic, clinical, therapeutic and outcome aspects of 9 cases which have been hospitalized in the intensive care unit and medecine service of the military hospital of Marrakech, between january 2001 and december 2004. Out of 68 patients admitted with symptomatic malaria during this period, 9 cases were considered as severe. All of them were male soldiers (mean age: 33,3 years), 7 of them have stayed in Democratic Republic of Congo, and 2 in Ivory Coast...

The aim of this report was the presentation of a falciparum malaria case originated from Mozambique and the evaluation of diagnostic and therapeutic approaches. Sixty years old Canadian male patient who has been working in Mozambique for 13 years was admitted to hospital with the complaints of high fever (39.6 degrees C), weakness, nausea and vomiting, when returned to Turkey. The patient was sleepiness and has undulating confusions with the laboratory findings of thrombocytopenia, hypoglycemia, hyperlactatemia, increased BUN/creatinine levels, increased LDH levels and hypocholesterolemia...

OBJECTIVES: Previous studies of a fixed combination including cotrimoxazole, rifampicin, and isoniazid (Cotrifazid) showed efficacy against resistant strains of Plasmodium falciparum in animal models and in small-scale human studies. We conducted a multicentric noninferiority trial to assess the safety and efficacy of Cotrifazid against drug-resistant malaria in Papua New Guinea. DESIGN: The trial design was open-label, block-randomised, comparative, and multicentric...
