A sulfone active against a wide range of bacteria but mainly employed for its actions against MYCOBACTERIUM LEPRAE. Its mechanism of action is probably similar to that of the SULFONAMIDES which involves inhibition of folic acid synthesis in susceptible organisms. It is also used with PYRIMETHAMINE in the treatment of malaria. (From Martindale, The Extra Pharmacopoeia, 30th ed, p157-8)
An enzyme of the oxidoreductase class that catalyzes the reaction 7,8-dihyrofolate and NADPH to yield 5,6,7,8-tetrahydrofolate and NADPH+, producing reduced folate for amino acid metabolism, purine ring synthesis, and the formation of deoxythymidine monophosphate. Methotrexate and other folic acid antagonists used as chemotherapeutic drugs act by inhibiting this enzyme. (Dorland, 27th ed) EC 18.104.22.168.
Folic Acid Antagonists
Diminished or failed response of an organism, disease or tissue to the intended effectiveness of a chemical or drug. It should be differentiated from DRUG TOLERANCE which is the progressive diminution of the susceptibility of a human or animal to the effects of a drug, as a result of continued administration.
Malaria caused by PLASMODIUM FALCIPARUM. This is the severest form of malaria and is associated with the highest levels of parasites in the blood. This disease is characterized by irregularly recurring febrile paroxysms that in extreme cases occur with acute cerebral, renal, or gastrointestinal manifestations.
Parasitic Sensitivity Tests
Infections of the BRAIN caused by the protozoan TOXOPLASMA gondii that primarily arise in individuals with IMMUNOLOGIC DEFICIENCY SYNDROMES (see also AIDS-RELATED OPPORTUNISTIC INFECTIONS). The infection may involve the brain diffusely or form discrete abscesses. Clinical manifestations include SEIZURES, altered mentation, headache, focal neurologic deficits, and INTRACRANIAL HYPERTENSION. (From Joynt, Clinical Neurology, 1998, Ch27, pp41-3)
A protozoan disease caused in humans by four species of the PLASMODIUM genus: PLASMODIUM FALCIPARUM; PLASMODIUM VIVAX; PLASMODIUM OVALE; and PLASMODIUM MALARIAE; and transmitted by the bite of an infected female mosquito of the genus ANOPHELES. Malaria is endemic in parts of Asia, Africa, Central and South America, Oceania, and certain Caribbean islands. It is characterized by extreme exhaustion associated with paroxysms of high FEVER; SWEATING; shaking CHILLS; and ANEMIA. Malaria in ANIMALS is caused by other species of plasmodia.
A group of recessively inherited diseases characterized by the intralysosomal accumulation of G(M2) GANGLIOSIDE in the neuronal cells. Subtypes include mutations of enzymes in the BETA-N-ACETYLHEXOSAMINIDASES system or G(M2) ACTIVATOR PROTEIN leading to disruption of normal degradation of GANGLIOSIDES, a subclass of ACIDIC GLYCOSPHINGOLIPIDS.
Drug Therapy, Combination
Inhibitory Concentration 50
A pyrimidine inhibitor of dihydrofolate reductase, it is an antibacterial related to PYRIMETHAMINE. It is potentiated by SULFONAMIDES and the TRIMETHOPRIM, SULFAMETHOXAZOLE DRUG COMBINATION is the form most often used. It is sometimes used alone as an antimalarial. TRIMETHOPRIM RESISTANCE has been reported.
Prenatal protozoal infection with TOXOPLASMA gondii which is associated with injury to the developing fetal nervous system. The severity of this condition is related to the stage of pregnancy during which the infection occurs; first trimester infections are associated with a greater degree of neurologic dysfunction. Clinical features include HYDROCEPHALUS; MICROCEPHALY; deafness; cerebral calcifications; SEIZURES; and psychomotor retardation. Signs of a systemic infection may also be present at birth, including fever, rash, and hepatosplenomegaly. (From Adams et al., Principles of Neurology, 6th ed, p735)
Pregnancy Complications, Parasitic
An alkaloid derived from the bark of the cinchona tree. It is used as an antimalarial drug, and is the active ingredient in extracts of the cinchona that have been used for that purpose since before 1633. Quinine is also a mild antipyretic and analgesic and has been used in common cold preparations for that purpose. It was used commonly and as a bitter and flavoring agent, and is still useful for the treatment of babesiosis. Quinine is also useful in some muscular disorders, especially nocturnal leg cramps and myotonia congenita, because of its direct effects on muscle membrane and sodium channels. The mechanisms of its antimalarial effects are not well understood.
Infection caused by the protozoan parasite TOXOPLASMA in which there is extensive connective tissue proliferation, the retina surrounding the lesions remains normal, and the ocular media remain clear. Chorioretinitis may be associated with all forms of toxoplasmosis, but is usually a late sequel of congenital toxoplasmosis. The severe ocular lesions in infants may lead to blindness.
An aminoquinoline that is given by mouth to produce a radical cure and prevent relapse of vivax and ovale malarias following treatment with a blood schizontocide. It has also been used to prevent transmission of falciparum malaria by those returning to areas where there is a potential for re-introduction of malaria. Adverse effects include anemias and GI disturbances. (From Martindale, The Extra Pharmacopeia, 30th ed, p404)
Somalia is located on the east coast of Africa on and north of the Equator and, with Ethiopia, Eritrea, Djibouti, and Kenya, is often referred to as the Horn of Africa. It comprises Italy's former Trust Territory of Somalia and the former British Protectorate of Somaliland. The capital is Mogadishu.
A pulmonary disease in humans occurring in immunodeficient or malnourished patients or infants, characterized by DYSPNEA, tachypnea, and HYPOXEMIA. Pneumocystis pneumonia is a frequently seen opportunistic infection in AIDS. It is caused by the fungus PNEUMOCYSTIS JIROVECII. The disease is also found in other MAMMALS where it is caused by related species of Pneumocystis.
A group of Indian Ocean Islands, the islands of Great Comoro, Anjouan, Mayotte, and Moheli, lying between northeast Mozambique and northwest Madagascar. The capital is Moroni. In 1914 they became a colony attached to Madagascar administratively and were made a French overseas territory in 1947. Except for Mayotte which remained French, Comoros became an independent republic in 1975. Comoros represents the Arabic qamar, moon, said by some scholars to be linked with the mystical Mountains of the Moon said to be somewhere in equatorial Africa. (From Webster's New Geographical Dictionary, 1988, p283 & Room, Brewer's Dictionary of Names, 1992, p122)
One of the Indian Ocean Islands off the southeast coast of Africa. Its capital is Antananarivo. It was formerly called the Malagasy Republic. Discovered by the Portuguese in 1500, its history has been tied predominantly to the French, becoming a French protectorate in 1882, a French colony in 1896, and a territory within the French union in 1946. The Malagasy Republic was established in the French Community in 1958 but it achieved independence in 1960. Its name was changed to Madagascar in 1975. (From Webster's New Geographical Dictionary, 1988, p714)
Central African Republic
Infections with species in the genus PNEUMOCYSTIS, a fungus causing interstitial plasma cell pneumonia (PNEUMONIA, PNEUMOCYSTIS) and other infections in humans and other MAMMALS. Immunocompromised patients, especially those with AIDS, are particularly susceptible to these infections. Extrapulmonary sites are rare but seen occasionally.
A country in western Africa, east of MAURITANIA and south of ALGERIA. Its capital is Bamako. From 1904-1920 it was known as Upper Senegal-Niger; prior to 1958, as French Sudan; 1958-1960 as the Sudanese Republic and 1959-1960 it joined Senegal in the Mali Federation. It became an independent republic in 1960.
A mammalian beta-hexosaminidase isoform that is a heteromeric protein comprized of both hexosaminidase alpha and hexosaminidase beta subunits. Deficiency of hexosaminidase A due to mutations in the gene encoding the hexosaminidase alpha subunit is a case of TAY-SACHS DISEASE. Deficiency of hexosaminidase A and HEXOSAMINIDASE B due to mutations in the gene encoding the hexosaminidase beta subunit is a case of SANDHOFF DISEASE.
AIDS-Related Opportunistic Infections
Opportunistic infections found in patients who test positive for human immunodeficiency virus (HIV). The most common include PNEUMOCYSTIS PNEUMONIA, Kaposi's sarcoma, cryptosporidiosis, herpes simplex, toxoplasmosis, cryptococcosis, and infections with Mycobacterium avium complex, Microsporidium, and Cytomegalovirus.
Polymerase Chain Reaction
In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.
Drug Resistance, Microbial
Multiple mechanisms of resistance to polyglutamatable and lipophilic antifolates in mammalian cells: role of increased folylpolyglutamylation, expanded folate pools, and intralysosomal drug sequestration. (1/949)Chinese hamster ovary PyrR100 cells display more than 1000-fold resistance to pyrimethamine (Pyr), a lipophilic antifolate inhibitor of dihydrofolate reductase. PyrR100 cells had wild-type DHFR activity, lost folate exporter activity, and had a 4-fold increased activity of a low pH folic acid transporter. Here we report on the marked alterations identified in PyrR100 cells compared with parental cells: 1) approximately 100-fold decreased folic acid growth requirement; 2) a 25-fold higher glucose growth requirement in Pyr-containing medium; 3) a 2.5- to 4.1-fold increase in folylpolyglutamate synthetase activity; 4) a 3-fold increase in the accumulation of [3H]folic acid and a 3-fold expansion of the intracellular folate pools; 5) a 4-fold increase in the activity of the lysosomal marker beta-hexoseaminidase, suggesting an increased lysosome number/PyrR100 cell; and 6) a small reduction in the steady-state accumulation of [3H]Pyr and no evidence of catabolism or modification of cellular [3H]Pyr. Consequently, PyrR100 cells were markedly resistant to the lipophilic antifolates trimetrexate (40-fold) and AG377 (30-fold) and to the polyglutamatable antifolates 5,10-Dideaza-5,6,7,8-tetrahydrofolic acid (DDATHF) (26-fold) and AG2034 (14-fold). Resistance to these drugs was reversed in PyrR100 cells transferred into folate-depleted medium. In conclusion, these multiple resistance factors collectively result in a prominent increase in folate accumulation, an expansion of the intracellular folylpolyglutamate pool, and abolishment of the cytotoxic activity of polyglutamatable and lipophilic antifolates. The role of increased lysosome number per cell in sequestration of hydrophobic weak base drugs such as Pyr is also discussed as a novel mechanism of drug resistance. (+info)
Antimalarial activities of various 9-phenanthrenemethanols with special attention to WR-122,455 and WR-171,669. (2/949)Pilot appraisals of the activities of 16 specially selected 9-phenanthrenemethanols against acute infections with Plasmodium falciparum in owl monkeys showed that all were more active than the reference compound, WR-33,063. WR-122,455, the most active derivative, and WR-171,669, ranked sixth, were selected for study in human volunteers. To assist this undertaking, appraisals of both compounds in owl monkeys infected with various strains of P. falciparum were expanded. These assessments showed: (i) that WR-122,455 was four times as active as chloroquine against infections with chloroquine-sensitive strains and that WR-171,669 equalled chloroquine in activity; (ii) that these compounds were fully active against infections with strains resistant to chloroquine, pyrimethamine, or quinine, or to all three standard drugs; (iii) that the activity of WR-122,455 was a function of total dose, single doses being as effective as the same amounts delivered in three or seven daily fractions; and (iv) that a single dose of WR-122,455 conferred extended, although only partial, protection against challenges with trophozoites. Complementary experiments in rhesus monkeys inoculated with sporozoites of P. cynomolgi showed that the activity of WR-122,455 was limited to blood schizonts and did not extend to early or late tissue schizonts. These evaluations were compatible with the results of preliminary studies of the activities of WR-122,455 and WR-171,669 in human volunteers. (+info)
Increased prevalence of malaria in HIV-infected pregnant women and its implications for malaria control. (3/949)OBJECTIVES: To examine in pregnant women the relationship between HIV infection and malaria prevalence and to determine, in relation to HIV infection, the effectiveness of sulphadoxine-pyrimethamine in clearing P. falciparum infection. METHOD: Descriptive cross-sectional analysis of P. falciparum prevalence in pregnant women at first antenatal visit and of women at delivery who had received two sulphadoxine-pyrimethamine treatments for malaria. HIV status was assessed in 621 women who attended for antenatal care and for delivery at two rural hospitals in southern Malawi in 1993-94. Information was collected on maternal age, parity and gestational age. Prevalence of P. falciparum was measured at first antenatal visit and delivery. Women were given two routine treatment doses of sulphadoxine-pyrimethamine (SP), at first antenatal visit and between 28 and 34 weeks gestation, conforming to Malawi government policy on antimalarial control during pregnancy. RESULTS: Prevalence of HIV infection was 25.6% and all infections were HIV type-1. In primigravidae malaria prevalence at recruitment was 56.3% in HIV-infected and 36.5% in HIV-uninfected women (P=0.04). The corresponding figures for multigravidae were 23.8% and 11.0%, respectively (P<0.01). HIV-infected primigravidae had increased malaria prevalence at all gestational ages. Peak parasite prevalence occurred earlier in gestation in HIV-infected primigravidae (16-19 weeks if HIV-infected; 20-23 weeks if HIV-uninfected). The relative risk for parasitaemia in HIV-infected compared to HIV-uninfected women was significantly increased in three of five parity groups, including the two highest ones (parity>3), indicating parity-specific immunity to malaria was impaired. Malaria prevalence at delivery remained high in HIV-infected women despite prior routine treatment with sulphadoxine-pyrimethamine in pregnancy There was no significant difference in parasite prevalence at delivery between women who did or did not use sulphadoxine-pyrimethamine. CONCLUSIONS: HIV infection is associated with a significant increase in malaria prevalence in pregnant women of all parities with the effect apparent from early in gestation. Two treatment doses of sulphadoxine-pyrimethamine were inadequate to clear parasitaemia in many women by the time of delivery and this occurred independently of HIV status and despite high sensitivity to SP in this area. There is a need to undertake longitudinal studies to determine the incidence of P. falciparum infection in HIV-infected and uninfected pregnant women and to reassess the frequency and timing of sulphadoxine-pyrimethamine treatment doses in these women. Late pregnancy re-infections with P. falciparum probably explain the high parasite prevalence at delivery following sulphadoxine-pyrimethamine treatment at 28-34 weeks gestation. (+info)
Response of falciparum malaria to different antimalarials in Myanmar. (4/949)The purpose of the study was to ascertain the therapeutic efficacy of different treatments for uncomplicated falciparum malaria in the hospitals in Sagaing, northern and eastern Shan, to facilitate updating the existing national antimalarial drug policy. The proposed 14-day trial for monitoring the efficacy of treatments of uncomplicated falciparum malaria is an efficient method for identifying treatment failure patterns at the intermediate level (township hospital) in the Union of Myanmar. Minimal clinical and parasitological data for days 0-14 were required to classify treatment failure and success. Clinical and parasitiological responses on day 3 and days 4-14 were used as clear examples of early and late treatment failure, respectively. Mefloquine is five times more likely to be effective than chloroquine and sulfadoxine pyrimethamine (S-P), whereas chloroquine and S-P treatments have nearly identical failure patterns. The alarming frequency of clinical and parasitological failure (failure rate > 50%) following chloroquine treatment was reported in Sagaing and following S-P treatment in Sagaing and eastern Shan.

Green fluorescent protein as a marker in Plasmodium berghei transformation. (5/949)We present a new marker that confers both resistance to pyrimethamine and green fluorescent protein-based fluorescence on the malarial parasite Plasmodium berghei. A single copy of the cassette integrated into the genome is sufficient to direct fluorescence in parasites throughout the life cycle, in both its mosquito and vertebrate hosts. Erythrocyte stages of the parasite that express the marker can be sorted from control parasites by flow cytometry. Pyrimethamine pressure is not necessary for maintaining the cassette in transformed parasites during their sporogonic cycle in mosquitoes, including when it is borne by a plasmid. This tool should thus prove useful in molecular studies of P. berghei, both for generating parasite variants and monitoring their behavior. (+info)
Atovaquone-proguanil compared with chloroquine and chloroquine-sulfadoxine-pyrimethamine for treatment of acute Plasmodium falciparum malaria in the Philippines. (6/949)This randomized, open-label clinical trial compared a fixed-dose combination of atovaquone and proguanil (n=55) with chloroquine (n=23) or a combination of chloroquine, sulfadoxine, and pyrimethamine (n=32) for treatment of acute falciparum malaria in the Philippines. Patients were hospitalized for 28 days to ensure medication compliance and prevent reinfection. Atovaquone-proguanil produced a significantly higher cure rate (100%) compared with that for chloroquine (30.4%; P<.0001) or chloroquine-sulfadoxine-pyrimethamine (87.5%; P<.05). Treatments did not differ significantly with respect to parasite clearance time (mean: 46.7 h for atovaquone-proguanil, 60.0 h for chloroquine, and 42.8 h for chloroquine-sulfadoxine-pyrimethamine) or fever clearance time (mean, 38.8, 46.8, and 34.5 h, respectively). Adverse events were typical of malaria symptoms; the most frequently reported events were vomiting (18% for atovaquone-proguanil, 17% for chloroquine, and 9% for chloroquine-sulfadoxine-pyrimethamine), abdominal pain (15%, 17%, and 3%, respectively), anorexia (11%, 13%, and 0%, respectively), and headache (6%, 17%, and 3%, respectively). Atovaquone-proguanil was well tolerated and more effective than chloroquine or chloroquine-sulfadoxine-pyrimethamine for treatment of multidrug-resistant falciparum malaria in the Philippines.

In vivo responses to antimalarials by Plasmodium falciparum and Plasmodium vivax from isolated Gag Island off northwest Irian Jaya, Indonesia. (7/949)There is renewed interest in the rich nickel and cobalt deposits of Pulau Gag, an isolated but malarious island off the northwest coast of Irian Jaya. In preparation for an expanded workforce, an environmental assessment of malaria risk was made, focusing upon malaria prevalence in the small indigenous population, and the in vivo sensitivity of Plasmodium falciparum and P. vivax to chloroquine (CQ) and sulfadoxine/pyrimethamine (S/P), the respective first- and second-line drugs for uncomplicated malaria in Indonesia. During April-June 1997, mildly symptomatic or asymptomatic malaria infections were found in 24% of 456 native residents. Infections by P. falciparum accounted for 60% of the cases. Respective day 28 cure rates for CQ (10 mg base/kg on days 0 and 1; 5 mg/kg on day 2) in children and adults were 14% and 55% (P < 0.005). Type RII and RIII resistance characterized only 5% of the CQ failures. Re-treatment of 36 P. falciparum CQ treatment failures with S/P (25 mg/kg and 1.25 mg/kg, respectively) demonstrated rapid clearance and complete sensitivity during the 28-day follow-up period. More than 97% of the P. vivax malaria cases treated with CQ cleared parasitemia within 48 hr. Three cases of P. vivax malaria recurred between days 21 and 28, but against low drug levels in the blood. The low frequency of RII and RIII P. falciparum resistance to CQ, the complete sensitivity of this species to S/P, and the absence of CQ resistance by P. vivax are in contrast to in vivo and in vitro test results from sites on mainland Irian Jaya.

Congenital toxoplasmosis: systematic review of evidence of efficacy of treatment in pregnancy. (8/949)OBJECTIVE: To summarise the evidence that treating toxoplasmosis in pregnancy reduces the risk of congenital toxoplasma infection and improves infant outcomes. DESIGN: Systematic review of studies comparing at least two concurrent groups of pregnant women with proved or likely acute toxoplasma infection in which treatments were compared with no treatment and outcomes in the children were reported. SUBJECTS: Studies were identified from Medline (1966-97), Pascal (1990-7), Embase (1993-7), and Biological abstracts (1993-5) plus contact with experts in the field, including the European Research Network on Congenital Toxoplasmosis. MAIN OUTCOME MEASURE: Proportion of infected children at 1 year born to infected pregnant women who were or were not treated. RESULTS: Out of 2591 papers identified, nine met the inclusion criteria. There were no randomised comparisons, and control groups were generally not directly comparable with the treatment groups. Congenital infection was common in treated groups. five studies showed that treatment was effective and four that it was not. CONCLUSION: It is unclear whether antenatal treatment in women with presumed toxoplasmosis reduces congenital transmission of Toxoplasma gondii. Screening is expensive, so the effects of treatment and impact of screening programmes need to be evaluated. In countries where screening or treatment is not routine, these technologies should not be introduced outside carefully controlled trials. (+info)
In Vitro Activity of Pyrimethamine, Cycloguanil, and Other Antimalarial Drugs Against African Isolates and Clones of Plasmodium...
Abstract The in vitro activity of two dihydrofolate reductase (DHFR) inhibitors, pyrimethamine and cycloguanil, was evaluated against African clones and isolates of Plasmodium falciparum using an isotopic, semimicro drug susceptibility test. Three susceptibility levels (susceptible, intermediate, and resistant) were observed in the response of culture-adapted clones and strains to pyrimethamine (50% inhibitory concentration [IC50]) < 100, 100-2,000, and > 2,000 nM) and cycloguanil (IC50 < 50, 50-500, and > 500 nM). Based on these susceptibility levels, 73 and 68 of 96 fresh clinical isolates were susceptible to pyrimethamine (mean IC50 15.4 nM) and cycloguanil (mean IC50 11.1 nM), respectively. Thirteen and 18 isolates were resistant to pyrimethamine (mean IC50 9,440 nM) and cycloguanil (mean IC50 2,030 nM), respectively. A highly significant positive correlation was found between pyrimethamine and cycloguanil (r = 0.786), indicating in vitro cross-resistance between these antifolates. The

Resistance to pyrimethamine is widespread. Mutations in the malarial gene for dihydrofolate reductase may reduce the effectiveness of pyrimethamine. These mutations decrease the binding affinity between pyrimethamine and dihydrofolate reductase via loss of hydrogen bonds and steric interactions.. Pyrimethamine interferes with tetrahydrofolic acid synthesis from folic acid by inhibiting the enzyme dihydrofolate reductase (DHFR). Tetrahydrofolic acid is needed for DNA and RNA synthesis in many species, including protozoa. Pyrimethamine has also found to inhibit SOD1, a key protein involved in ALS. ...
Intermittent preventive therapy - Wikipedia
Intermittent preventive therapy or intermittent preventive treatment (IPT) is a public health intervention aimed at treating and preventing malaria episodes in infants (IPTi), children (IPTc), schoolchildren (IPTsc) and pregnant women (IPTp). The intervention builds on two tested malaria control strategies to clear existing parasites (treatment effect seen in mass drug administrations) and to prevent new infections (prophylaxis). IPTi using the antimalarial drug sulfadoxine/pyrimethamine (S/P) was pioneered in Ifakara, Tanzania in 1999. Infants received S/P at ages 3, 6, and 9 months in combination with their routine childhood (EPI) vaccinations. IPTi reduced clinical attacks of malaria by 59% (95% CI, 41%-72%) in Ifakara. Remarkably, protection persisted throughout the second year of life, long after SP had disappeared from circulation. A trial conducted in northern Tanzania using the antimalarial drug amodiaquine instead of S/P was similarly successful. Six subsequent trials showed less ...

Encephalitis caused by Toxoplasma gondii is the most frequent cause of focal central nervous system infection in patients with AIDS. Untreated, the encephalitis is fatal. Standard treatment for toxoplasmic encephalitis is associated with serious adverse effects. Thus, alternative treatments are needed.. Patients with toxoplasmosis are given azithromycin at doses starting at the lowest dose for the first cohort, an intermediate dose for the second cohort, and a higher dose for the third cohort. Subsequent cohorts may receive azithromycin in increased dosage, if needed to determine the MTD. All patients also receive pyrimethamine. Folinic acid is also provided for as long as patients receive pyrimethamine. Patients are evaluated for clinical response to treatment at days 3, 7, and 14, and weekly for 6 weeks. Maintenance treatment with azithromycin continues for an additional 24 weeks. Patients who complete the study period without relapse or significant toxicity are offered continued therapy by ...
Malaria intermittent preventive treatment in Nigeria: a qualitative study to explore barriers | BMC Infectious Diseases | Full...
While the use of sulphadoxine pyrimethamine (SP) is effective in preventing malaria infection during pregnancy, there are challenges limiting its uptake in Nigeria. This study aimed at exploring the barriers to IPTp usage among pregnant women in Kano state - Nigeria. This is a qualitative study. The purposive sampling strategy was used for identification and selection of 14 key informants for interviews. In addition, six focus group discussions (FGDs) were conducted with pregnant women (3 FGDs) and married men (3 FGDs). The conventional content analysis method was used to interpret meaning from the content of the data. MAXQDA 10 software was used for data management and analysis. Poor policy implementation, poor antenatal care attendance, inadequate access to intermittent preventive treatment at the community levels, lack of sustainable funding, and poor community engagement emerged as major barriers to IPTp use in Nigeria. While the political will to allocate sufficient financial resources could help
Rare, highly pyrimethamine-resistant alleles of the Plasmodium falcipa by S.J. Bates, P.A. Winstanley et al.
In eastern and southern Africa, there has been a rapid increase in the prevalence of alleles with mutations in the Plasmodium falciparum dihydrofolate reductase gene (dhfr) associated with increased risk of clinical failure of sulfadoxine-pyrimethamine (S/P). Molecular methods for surveillance of these mutations are now widespread, but the usual analysis detects only the most prevalent allele in a polyclonal sample. We used a yeast-expression system to identify rare, highly pyrimethamine-resistant alleles of dhfr in isolates from 5 African countries-Kenya, Tanzania, Malawi, Gabon, and Nigeria. Only the isolates from Nigeria yielded significant numbers of novel resistant alleles, and only 1 of the alleles from any location showed a |3-fold increase in resistance to S/P or to chlorproguanil-dapsone. Overall, these results suggest that dhfr alleles that confer high levels of resistance to antifolates are rare, even in eastern and southern Africa, where pyrimethamine has been intensively used.

Repositorio da Producao Cientifica e Intelectual da Unicamp: Inclusion complexes of pyrimethamine in 2-hydroxypropyl-beta...
The inclusion complexation of pyrimethamine in 2-hydroxypropyl-beta-cyclodextrin has been investigated by 2D H-1 NMR, FTIR and UV/visible spectroscopy and also by molecular modelling methods (AM1, PM3, MM3). From the phase-solubility diagram a linear increase was observed in pyrimethamine aqueous solubility in the presence of 2-hydroxypropyl-beta-cyclodextrin, evidencing the formation of a soluble inclusion complex. According to the continuous variation method (Jobs plot) applied to fluorescence measurements, a 1:1 stoichiometry has been proposed for the complex. Concerning the structure of the complex, a Cl-in orientation of pyrimethamine in the 2-hydroxypropyl-o-cyclodextrin cavity has been proposed from the theoretical calculations, being confirmed by two-dimensional H-1 NMR spectroscopy (ROESY). The thermal behaviour has also been studied, providing complementary evidences of complex formation. (c) 2007 Elsevier Ltd. All rights reserved ...

Well, it looks like I got my wish. As previously reported, a few days ago rare Smiths and Morrissey demos circulated to the surface of the Internet and were publicized on Morrissey-solo. As a disclaimer, I was aware some of these demos had existed in the collections of certain diehards but were not available on any major published bootlegs. As bootlegs collectors like myself know, a plethora of selfish collectors of certain music exist - and if they come all along something rare, they will oftentimes not share with a community of people who might be interested in it. Why else did Martin Shkreli raise the price of Pyrimethamine (trade name Daraprim) from $13 a pill to $833? But I digress…. The good news is that, right before 2016, even more demos, rare, uncommon, uncirculated or unheard, were publicized to the larger community of Morrissey fans on Morrissey-solo. While the site has a disputable reputation with Morrissey, many of their members can be quite resourceful.. Some of these unreleased ...

Researchers sought to determine the most effective regimen of intermittent preventive treatment (IPT) against malaria for schoolchildren in the Democratic Republic of Congo. The children were given sulfadoxine/pyrimethamine (SP), SP plus piperaquine (SP/PQ), or no intervention. The SP group saw a reduction in anemia (10%), malaria parasitemia (19%), and clinical malaria (25%),
Pyrimethamine for the Treatment of Relapsed Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma - Tabular View -...
In this research study we will start by looking for the highest dose of pyrimethamine that can be given safely to CLL patients without severe or unmanageable side effects. This dose will then be used for a larger Phase II study to assess the efficacy of pyrimethamine for the treatment of CLL/SLL. Pyrimethamine is an antibiotic that is used for the treatment of certain infections. Previous research studies have shown that pyrimethamine may target a protein in tumor cells, called STAT3, which may be important for the growth of chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) cells. Pyrimethamine can kill CLL/SLL cells in the laboratory, and we are therefore undertaking this study to assess whether pyrimethamine will result in clinical benefit or tumor responses in CLL in patients ...
High prevalence and fixation of Plasmodium vivax dhfr/dhps mutations related to sulfadoxine/pyrimethamine resistance in French...
Plasmodium vivax isolates from French Guiana were studied for the presence of mutations associated with sulfadoxine/pyrimethamine (SP) drug resistance. Ninety-six blood samples were collected from 2000 to 2005 from symptomatic malaria patients. SP drug resistance was predicted by determining point mutations in the dihydrofolate reductase (pvdhfr) and dihydropteroate synthase (pvdhps) genes. All samples showed mutant genotypes in both genes with a prevalence | 90% for the 58R, 117N, 382C, and 383G. A new mutation (116G) in pvdhfr was found at a frequency of 3.3%. Six different pvdhfr/dhps multilocus genotypes were observed with the predominance of the quintuple mutant-type 58R/117N/173L-382C/383G (59.3%). No significant differences were observed between the prevalence of haplotypes and the year of collection. Our results indicate that, in this area, the fixation of SP drug-resistant parasites in the P. vivax population is stable.
Parasite clearance following treatment with sulphadoxine-pyrimethamine for intermittent preventive treatment in Burkina-Faso...
Intermittent Preventive Treatment in pregnancy (IPTp) with sulphadoxine-pyrimethamine (SP) is widely used for the control of malaria in pregnancy in Africa. The emergence of resistance to SP is a concern requiring monitoring the effectiveness of SP for IPTp. This was an in-vivo efficacy study to determine the parasitological treatment response and the duration of post-treatment prophylaxis among asymptomatic pregnant women receiving SP as part of IPTp in Mali and Burkina-Faso. The primary outcome was the PCR-unadjusted % of patients with parasites recurrence by day 42 defined as a positive diagnostic test by malaria smear at any visit between days 4 and 42. Treatment failure was based on the standard World Health Organization criteria. The therapeutic response was estimated using the Kaplan-Meier curve. A total of 580 women were enrolled in Mali (N=268) and Burkina-Faso (N=312) and followed weekly for 42 days. Among these, 94.3% completed the follow-up. The PCR-unadjusted cumulative risk of recurrence

In the Maheba Refugee Settlement, in the clinics supported by Medecins Sans Frontieres, all children aged up to 5 years with a confirmed diagnosis of uncomplicated falciparum malaria are treated with the combination of sulfadoxine/pyrimethamine (SP) and artesunate (AS). We compared the treatments efficacy and effectiveness. Patients were randomized in order to receive the treatment supervised (efficacy) or unsupervised (effectiveness). Therapeutic response was determined after 28 days of follow up. The difference between recrudescence and re-infection was ascertained by polymerase chain reaction (PCR). We also assessed genetic markers associated to SP resistance (dhfr and dhps). Eighty-five patients received treatment under supervision and 84 received it unsupervised. On day 28, and after PCR adjustment, efficacy was found to be 83.5% (95% CI: 74.1-90.5), and effectiveness 63.4% (95% CI: 52.6-73.3) (P , 0.01). Point mutations on dhfr (108) and dhps (437) were found for 92.0% and 44.2% ...

Sulfadoxine - Science of Acne
Sulfadoxine (Sulphadoxine) is an antibiotic in the Sulfonamide family. It is primarily used in combination with Pyrimethamine for the treatment of malaria.. Sulfadoxine is rarely used as a treatment for acne. There is minimal clinical research or laboratory testing on the utility of Sulfadoxine as an acne treatment. Laboratory testing indicates that the acne-causing P. acnes bacterium is tends to be moderately sensitive to Sulfonamide family antibiotics, such as Sulfadoxine.. For the treatment of active acne symptoms, other Sulfonamide family antibiotics (eg. Sulfamethoxazole, Dapsone. Sulfadiazine) are more commonly prescribed.. ...

The study investigated pregnant womens perceptions, beliefs and practices on the use of Sulphadoxine Pyrimethamine (SP) for primary prevention of malaria in pregnancy. The objectives included assessing pregnant womens knowledge and benefits of antenatal care services, attitudes and practices on antenatal clinic attendance and perceptions regarding the use of Sulphadoxine Pyrimethamine (SP) in pregnancy. An exploratory qualitative research method was used. The population included all pregnant women in a Municipality. Sampling was purposive and the sample size was (14) based on saturation. A semi-structured interview guide was used to conduct in-depth interviews among pregnant women in homes. The Tesch in Creswell (2009) content analysis protocol was used to analyze the data. Five overarching themes emerged with several categories including bizarre beliefs about the dangerous effects of the three tablets dosage of SP on the foetus. The study concluded there was lack of health education for ...
Intermittent preventive treatment of malaria in pregnancy: a cross-sectional survey to assess uptake of the new sulfadoxine...
Results of the current study revealed that most of the study participants (90.6%) registered for their first ANC visit during the first or second trimester of pregnancy. Majority of them (88.6%) made at least four visits before delivery, as recommended by the WHO in the previous policy on ANC visits but only 3.9% made the required eight visits per the new policy . Most of these women (56%) received four or more doses of SP with 86.5% of the first doses being taken during the second trimester. Stock-out of SP was not observed during the period under review (Fig. 3).. Antenatal care services are essential services designed to improve maternal and new born health. Although timely ANC visit is necessary for early detection and management of pregnancy related problems, many mothers do not receive such care  especially in low income countries and this could have negative consequences on overall perinatal outcomes. According to , trends in most sub-Saharan countries seem to suggest that ...

Mutational analysis of Plasmodium falciparum dihydrofolate reductase: the role of aspartate 54 and phenylalanine 223 on...
The catalytic activity and ability to confer resistance to antifolates of Plasmodium falciparum dihydrofolate reductase (pfDHFR) through single and double mutations at Asp-54 and Phe-223 were investigated. A single Asp54Glu (D54E) mutation in the pfDHFR domain greatly decreased the catalytic activity of the enzyme and affected both the K, values for the substrate dihydrofolate and the K-i values for pyrimethamine, cycloguanil and WR99210. The Phe223Ser (F223S) single mutant had unperturbed kinetics but had very poor affinity with the first two antifolates. The ability to confer high resistance to the antifolates of F223S enzyme was, however, abolished in the D54E + F223S double mutant enzyme. When D54E mutation was present together with the A16V + S108T double mutation, the effects on the Km values for the substrate dihydrofolate and the binding affinity of antifolates were much more pronounced. The severely impaired kinetics and poor activity observed in A16V+S108T+D54E enzyme could, however, ...
Sulphadimidine, pyrimethamine and dapsone in the treatment of toxoplasmosis in mice. - Semantic Scholar
Sulphadimidine, dapsone, and pyrimethamine have been tested alone and in various combinations for their therapeutic effect against toxoplasma infection in mice. In the treatment of active infection, sulphadimidine by itself was effective, but relapses were common. Pyrimethamine gave complete cures and prevented the carrier state when used in doses near to the toxic level. Dapsone alone was not as good as either of the other two drugs tested. The best combination was found to be sulphadimidine and pyrimethamine, which were synergic. In doses well below the toxic level, this combination not only controlled the acute infection but also prevented relapses and the development of the carrier state. Dapsone and pyrimethamine were also synergic, but were not as effective as the previous combination. No synergy was found between dapsone and sulphadimidine. The mechanism of relapse and the development of the carrier state and the modes of action of the drugs alone and in combination are discussed.

Sulphadoxine-pyrimethamine (SP), an antifolate, was replaced by artemether-lumefantrine as the first-line malaria drug treatment in Kenya in 2004 due to the wide spread of resistance. However, SP still remains the recommended drug for intermittent preventive treatment in pregnant women and infants (IPTP/I) owing to its safety profile. This study assessed the prevalence of mutations in dihydrofolate reductase (Pfdhfr) and dihydropteroate synthase (Pfdhps) genes associated with SP resistance in samples collected in Kenya between 2008 and 2012.. ...
The role of sequential administration of sulphadoxine/pyrimethamine following quinine in the treatment of severe falciparum...
Sulphadoxine/pyrimethamine (SP) is often administered with quinine in the treatment of severe falciparum malaria to shorten the course of quinine. The efficacy of SP alone in the treatment of non-severe malaria has been declining rapidly in East Africa, raising concerns of the usefulness of a shortened course of quinine followed SP. We audited the efficacy of quinine/SP in the treatment of severe malaria in Kenyan children. Children with severe falciparum malaria were treated with parenteral quinine followed by a single oral dose of SP. A clinical evaluation was performed 3 weeks later in which a blood sample was obtained for full haemogram, blood slide and analysis of the parasite dihydrofolate reductase (DHFR) and dihydropteroate synthase (DHPS) codons, mutations of which are associated with resistance to SP. A total of 452 children were enrolled, of whom 374 completed the study. Fifty-two (13.9%) children were parasitaemic by 3 weeks of whom 17 (4.5%) had fever as well. The treatment failure group
Intermittent preventive treatment against malaria: an update. - LSHTM Research Online | London School of Hygiene and Tropical...
Intermittent preventive treatment (IPT) against malaria is a malaria control strategy aimed at reducing the burden of malaria in certain high-risk groups, namely pregnant women and children. Three strategies - IPT in pregnancy (IPTp), infants (IPTi) and children (IPTc) - are reviewed here focusing on the mechanism of action, choice of drugs available, controversies and future research. Drugs for IPT need to be co-formulated, long acting, safe and preferably administered as a single dose. There is no obvious replacement for sulfadoxine-pyrimethamine, the most commonly utilized drug combination. All strategies face similar problems of rising drug resistance, falling malaria transmission and a policy shift from controlling disease to malaria elimination and eradication. IPT is an accepted form of malaria control, but to date only IPTp has been adopted as policy.. ...
Isospora belli Infection: Treatment with Pyrimethamine | Annals of Internal Medicine | American College of Physicians
Isosporiasis is an uncommon but important diarrheal disease of humans that, like cryptosporidiosis, is life-threatening in patients with the acquired immunodeficiency syndrome (AIDS). Isospora belli infection responds rapidly to therapy with trimethoprim-sulfamethoxazole, but patients with AIDS have a high rate of adverse reactions to this therapy. The cases of two patients with AIDS, sulfonamide allergy, and I. belli infection are reported. They were treated successfully with pyrimethamine alone, 75 mg/d, and recurrence was prevented with daily pyrimethamine therapy, 25 mg/d. In patients with AIDS with sulfonamide allergy or intolerance, pyrimethamine alone seems to be a reasonable alternative therapy for I. belli infection. ...

Amodiaquine for treating malaria. - GOV.UK
Main results: 56 studies included, mostly from Africa. Treatment allocation was adequately concealed in three trials, and unclear or inadequate in the remainder. Amodiaquine was more effective than chloroquine for parasite clearance (day 7, Peto odds ratio 4.42 (95% confidence interval 3.65 to 5.35); day 14, Peto odds ratio 6.44 (95% confidence interval (CI) 5.09 to 8.15). Comparisons with sulfadoxine/pyrimethamine were more mixed, with sulfadoxine/pyrimethamine more effective on day 28 (Peto odds ratio 0.41; 95% CI 0.28 to 0.61). No significant difference for adverse events was observed between amodiaquine and chloroquine and sulfadoxine/pyrimethamine. Reported adverse effects were minor or moderate. No life threatening events were detected ...
LSHTM Research Online
Pregnant women and their unborn children are vulnerable to malaria, increasing the risk of maternal anaemia, low birthweight (LBW) and intrauterine growth retardation. There is little evidence on the cost-effectiveness of intermittent preventive treatment in pregnancy (IPTp) and insecticide-treated bednets (ITN) in areas of low transmission. A randomised controlled trial with three arms was conducted in antenatal clinics in Kabale District (Uganda), an epidemic-prone highland area of low malaria transmission. The interventions were: (i) IPTp with sulfadoxine/pyrimethamine (SP) given twice during pregnancy (IPTp-SP); (ii) ITNs alone; and (iii) a combined intervention with both ITNs and IPTp-SP. Primary health outcomes were LBW and maternal anaemia. The costs of providing IPTp-SP and ITNs as well as treatment of malaria episodes were captured from all health centres in the study area. There were no significant differences in health outcomes among the three interventions. The cost-effectiveness ...

Labs | Infectious Diseases | Stanford Medicine
BACKGROUND: Intermittent preventive treatment of malaria in pregnancy (IPTp) with dihydroartemisinin-piperaquine (IPTp-DP) has been shown to reduce the burden of malaria during pregnancy compared to sulfadoxine-pyrimethamine (IPTp-SP). However, limited data exist on how IPTp regimens impact malaria risk during infancy. We conducted a double-blinded randomized controlled trial (RCT) to test the hypothesis that children born to mothers given IPTp-DP would have a lower incidence of malaria during infancy compared to children born to mothers who received IPTp-SP.METHODS AND FINDINGS: We compared malaria metrics among children in Tororo, Uganda, born to women randomized to IPTp-SP given every 8 weeks (SP8w, n = 100), IPTp-DP every 8 weeks (DP8w, n = 44), or IPTp-DP every 4 weeks (DP4w, n = 47). After birth, children were given chemoprevention with DP every 12 weeks from 8 weeks to 2 years of age. The primary outcome was incidence of malaria during the first 2 years of life. Secondary outcomes ...
Strengthening IPTP Service Delivery Through Facility Initiated Supervision | Management Sciences for Health
Malaria contributes significantly to maternal mortality and morbidity in Sub-Saharan Africa. Preventing malaria among pregnant women is an important strategy for reducing mortality and adverse maternal and neonatal health outcomes. The World Health Organization recommends intermittent preventive treatment for pregnant women (IPTp) at each scheduled antenatal care visit starting early in the second trimester as a key strategy for prevention. This study, conducted in two districts in Uganda, explored service delivery practices, missed opportunities, and barriers at the facility level that impede IPTp service provision.. ...

Coartem is provided without profit to developing countries using grants from the Global Fund to Fight AIDS, Tuberculosis and Malaria, US President's Malaria Initiative along with other donors. Novartis has lowered the price of Coartem by 50% since 2001, increasing access to patients around the world. The first significant price reduction occurred in 2006, when the price of Coartem decreased from an average of US $1.57 to US $1.00. In 2006, due to an improved supply situation for the natural ingredient artemisinin, Novartis was able to undertake the pharmaceutical industry's most aggressive manufacturing scale-up of its kind from 4 million treatments in 2004 to 62 million treatments in 2006. Novartis and its partners invested heavily in expanding production capacity at their facilities in China, and Suffern, New York. This increase in production capacity ensured that supplies of Coartem met demand which enabled Novartis to further decrease the price of Coartem. In April 2008, ...
... is widely used to treat infections of Giardia in dogs, cats, and other companion animals, although it does not reliably clear infection with this organism and is being supplanted by fenbendazole for this purpose in dogs and cats. It is also used for the management of chronic inflammatory bowel disease in cats and dogs. Another common usage is the treatment of systemic and/or gastrointestinal clostridial infections in horses. Metronidazole is used in the aquarium hobby to treat ornamental fish and as a broad-spectrum treatment for bacterial and protozoan infections in reptiles and amphibians. In general, the veterinary community may use metronidazole for any potentially susceptible anaerobic infection. The U.S. Food and Drug Administration (FDA) suggests it only be used when necessary because it has been shown to be carcinogenic in mice and rats, as well as to prevent antimicrobial resistance. ...
... is a form of aminoquinoline with an amine at the 8-position of quinoline. The 8-aminoquinoline family of drugs contains three members, primaquine, tafenoquine and pamaquine and are used in the treatment of malaria. They may be used to eradicate malaria hypnozoites from the liver and have both been used for malaria prophylaxis. The 8-aminoquinoline drugs must not be given to patients with G6PD deficiency, because they cause potentially fatal haemolysis in these patients. Pamaquine is no longer available anywhere, but primaquine is still used routinely worldwide as part of the treatment of Plasmodium vivax and Plasmodium ovale malaria. Tafenoquine is currently in Phase III clinical trials and is not yet available to prescribe. ...
... is primarily used to prevent relapse of malaria due to Plasmodium vivax and Plasmodium ovale. It eliminates hypnozoites, the dormant liver form of the parasite, after the organisms have been cleared from the bloodstream. If primaquine is not administered to patients with proven P. vivax or P. ovale infection, a very high likelihood of relapse exists for weeks or months (sometimes years). Use in combination with quinine or chloroquine each of which is very effective at clearing P. vivax from blood, improves outcomes; they appear to also potentiate the action of primaquine. As of 2016, the Centers for Disease Control and Prevention recommended the use of primaquine for primary prophylaxis prior to travel to areas with a high incidence of P. vivax, and for terminal prophylaxis (anti-relapse therapy) after travel. A single dose of primaquine has rapid and potent ability to kill gametocytes (stage V) of P. falciparum and P. vivax in blood; it also kills asexual ...
... was formulated at Walter Reed Army Institute of Research (WRAIR) in the 1970s shortly after the end of the Vietnam war. Mefloquine was number 142,490 of a total of 250,000 antimalarial compounds screened during the study. Mefloquine was the first Public-Private Venture (PPV) between the US Department of Defense and a pharmaceutical company. WRAIR transferred all its phase I and phase II clinical trial data to Hoffman LaRoche and Smith Kline. FDA approval as a treatment for malaria was swift. Most notably, phase III safety and tolerability trials were skipped. The drug was first approved and sold on a commercial basis in Switzerland in 1985. However, mefloquine was not approved by the FDA for prophylactic use until 1989. This approval was based primarily on compliance, while safety and tolerability were overlooked. Because of the drug's very long half-life, the Centers for Disease Control originally recommended a mefloquine dosage of 250 mg every two weeks; however, this ...

Artemizinin - Wikipédia
A artemizinin hatásmechanizmusa pontosan nem ismert és jelenleg is vizsgálat alatt áll. Amikor a maláriát okozó parazita megfertőzi a vörösvérsejtet, a hemoglobinből hemet szabadít fel, amely egy vas-porfirin komplex. A vas redukálja az artemizinin peroxidkötését és egy magas vegyértékű vas-oxo vegyületet hoz létre, amely egy reakciósorozatot indít be és reaktív oxigén gyökök jönnek létre, melyek megölik a parazitát. Az artemisinin sikerrel kecsegtet a rák gyógyításában is, ugyanis rákbetegek testéből származó szöveteken végzett kísérletek során a kutatók azt az eredményt kapták, hogy az artemizinin, in vitro 1200-szor több rákos sejtet pusztít el, mint egészségeset. ...
