On the other hand, azt may block the activity of pyrimethamine in mice, underscoring the need for access to more than one anti-hiv drug for people requiring treatments for opportunistic infections.
Toxoplasmosis is the most common cause of posterior segment inflammation worldwide. The protozoan parasite Toxoplasma gondii is the organism responsible for this necrotizing retinochoroiditis. A sudden unilateral decreased vision arising from a unifocal area of inflammation adjacent to a pigmented scar is virtually always of toxoplasmic origin. Even though no controlled studies have been designed to prove the efficacy of treating toxoplasmosis retinochoroiditis, most practitioners still implement treatment when the lesion is extremely large or the lesion is threatening the macula or optic nerve. To date, no treatments offer a cure, and all treatment regimens have their particular side effects. Remember, the infection is usually self-limited, so without treatment it will resolve spontaneously, although recovery will probably be slower and it may leave a larger scar in its wake. For almost 50 years, therapy has consisted of pyrimethamine DaraprimTM ; , sulfadiazine and folinic acid.

History of Pyrimethamine
Formulations Sulfadoxinepyrimethamine: Tablets containing 500 mg of sulfadoxine and 25 mg of pyrimethamine. Ampoules containing 500 mg of sulfadoxine and 25 mg of pyrimethamine in 2.5 ml of injectable solution. Sulfalenepyrimethamine: Tablets containing 500 mg of sulfalene and 25 mg of pyrimethamine. Efficacy Sulfa drugpyrimethamine combinations are highly active blood schizonticides . against P falciparum but are less effective against other Plasmodium species. There is no cross-resistance with the 4-aminoquinolines, mefloquine, quinine, halofantrine or the artemisinin derivatives. The combinations do not have gametocytocidal activity but have been shown to be sporontocidal in animal models. The long half-life of sulfa drugpyrimethamine combinations provides a potent selective pressure for parasite resistance in areas of high transmission. In Africa since the late 1980s, P falciparum sensitivity has decreased, particularly in East . Africa where sulfadoxinepyrimethamine has been used on a large scale 130132 ; , and resistance is demonstrable in parts of West Africa 133 ; . At.

A high-throughput growth assay for the protozoan parasite Toxoplasma gondii was developed based on a highly fluorescent transgenic parasite line. These parasites are stably transfected with a tandem yellow fluorescent protein YFP ; and are 1, 000 times more fluorescent than the wild type. Parasites were inoculated in optical-bottom 384-well culture plates containing a confluent monolayer of host cells, and growth was monitored by using a fluorescence plate reader. The signal was linearly correlated with parasite numbers over a wide array. Direct comparison of the YFP growth assay with the -galactosidase growth assay by using parasites expressing both reporters demonstrated that the assays' sensitivities were comparable but that the accuracy of the YFP assay was higher, especially at higher numbers of parasites per well. Determination of the 50%-inhibitory concentrations of three known growth-inhibiting drugs cytochalasin D, pyrimethamine, and clindamycin ; resulted in values comparable to published data. The delayed parasite death kinetics of clindamycin could be measured without modification of the assay, making this assay very versatile. Additionally, the temperature-dependent effect of pyrimethamine was assayed in both wild-type and engineered drug-resistant parasites. Lastly, the development of mycophenolic acid resistance after transfection of a resistance gene in T. gondii was followed. In conclusion, the YFP growth assay limits pipetting steps to a minimum, is highly versatile and amendable to automation, and should enable rapid screening of compounds to fulfill the need for more efficient and less toxic antiparasitic drugs. Toxoplasma gondii is a widespread apicomplexan parasite able to infect virtually all warm-blooded vertebrates 45 ; . Twenty-two percent of the U.S. population is infected, but severe disease in adults is mainly limited to immunosuppressed patients. In patients with acquired immunodeficiency syndrome AIDS ; , T. gondii causes a life-threatening opportunistic infection, with Toxoplasma encephalitis as its most severe manifestation 23, 24 ; . T. gondii is also known to cause congenital infection and is among the pathogens with the highest incidence of complications in pregnancies 7, 31 ; . Despite its clinical importance, only very few therapeutic drugs against T. gondii are available, all of which target the rapidly dividing tachyzoites, leaving the dormant encysted bradyzoite stage unaffected 15, 22, 42 ; . As Toxoplasma encephalitis in AIDS patients results mostly from the reactivation of chronic stages 23 ; , this is an important shortcoming, severely compromising the management of toxoplasmosis in these patients. Moreover, drug toxicity due to sulfadiazine hypersensitivity further complicates the life-long prophylactic treatment of immunosuppressed patients 15, 22 ; as well as treatment during pregnancy. New drugs with broader efficacy and lower toxicity are clearly needed. Several microtiter plate-based growth assays for T. gondii drug screens have been developed in the past. Parasite growth can be measured by following the incorporation of radioactive uracil 30 ; , by using T. gondii-specific antibodies in an enzymelinked immunosorbent assay format 6, 26 ; , or by using trans * Corresponding author.

| Ten-fold coordination 1.52 A ; and Y in eight-fold coordination 1.03 A ; as well as 1.37 A computed for the ionic radii of oxygens. We see that the Ba ion is too big while the Y ion is too small. The oxygen ions will then tend to move away from the Ba ions. The chain oxygens Oi ; are fixed rigidly on the b axis while the bridging O4 oxygens are fixed on the c axis since they are surrounded on all sides by Ba ions. The oxygens in the CuO2 planes can be displaced however. In Fig. lb we show the new positions after the displacement keeping the dimensions of the unit cell fixed. The sizes of the Ba and Y ions are now commensurate with the space available to them. One may make a simple estimate of the limiting size of the ion at the Y site and we find it to be close to 1.1 A which is just below that of P r ions in eight-fold coordination 1.12 A ; . This limiting size is consistent with the fact mat La ions are not easily substituted exclusively at the Y site and always seems to require the substitution of some of the Ba ions by La ions as well. We believe that such a limiting size is also consistent with the localisation of holes on Pr in PrBa2Cu3O7 since it would help the Pr ions to reduce its size by increasing its average oxidation state . Ions such as Y + which have a smaller radius may induce an orthorhombic distortion a tx3.88 A ; because of the resultant decrease in the unit-cell volume.The above model accounts naturally for the predominant substitution of La or ions at Ba sites and Ca ions at Y sites in Lai.xPrxCaBaCu3O7. If we substitute S r + ions 1.26 A in eight-fold coordination ; at the Y site then the limiting size for the ion at the Ba site is 1.40 A. This accounts for the fact that Y cannot be substituted by Sr ion in YBa2Cu3 7 but may be substiuted by Ca 2 However, since the size of S r ion in ten-fold coordination is 1.36 A we may visualise a solid solution Yi-xSrxBa2-2ySr2yCu3O7 yx ; which implies that a susbtitution of Y by becomes possible when at least the two Ba ions in the same unit cell are substituted by Sr ions. We find that solid solutions with x y 0.25 is indeed possible. The ac susceptibility of these compounds suggests that Sr substitution at Y site is associated with a local destruction of superconductivity. The pressure of the large Ba ions on the oxygens in the O1O2 planes is possible because of the presence of the CuO chains. We believe that these chains are to be associated with the ARO layers such as the T1O layers in TlBa2CaCu2O7. The pressure on the Q1O2 planes ensures the presence of oxygen vacancies between the Q1O2 planes even after doping in the planes. In the absence of susch ARO layers as in La2SrCu2O6 or La2CaCu2O6there seems to be a tendency for a reorientation of the [G1Q4] square-planar units perpendicular to the O1O2 planes. This is apparent in compounds such as La2-xSn + xCu2O6 where an attempt is made to dope holes by the substitution of La by Sr. Substitution of Ba by may lead to a similar effect The pressure due to Ba leads to very short Ba-O distances. For example, the Ba-CM distance is only 2.74 A compared to the value of 2.92 A calculated from ionic radii. This pressure on the oxygen could be responsible for the short O11-O4 distance that is observed . On the other hand Ae pressure on the oxygen could also be responsible for the creation of holes on the O4 oxygens since this would reduce the size. Replacement of Ba by smaller ions such as La or would relieve the pressure on the 64 oxygens. We.

Infection in Kenya but resistance to SP is already reported. The addition of artemisinin derivatives to SP may delay the development of drug resistance, improve cure rates, and reduce transmission. The efficacy and safety of artesunate plus SP in the treatment of uncomplicated P. falciparum malaria was evaluated in a randomized trial of 600 children at Siaya District Hospital, western Kenya between October 1999 and March 2000. Children aged 5 years were randomly assigned to receive SP alone 1.25 mg kg based on pyrimethamine ; , or in combination with artesunate 4 mg kg d ; for either 1 or 3 Parasitological failure by days 14 and 28 polymerase chain reaction [PCR]-corrected for new infections ; were the primary endpoints. Treatment failure rates by day 14 were 25.5% in the SP alone group, 16.2% risk difference [delta]-9.3%, 95% CI -17.3 to -1.2%, P 0.027 ; in the 1-dose artesunate group, and 9.4% delta-16.2%, 95% CI -23.6 to 8.7%, P 0.001 ; in the 3-dose artesunate group. Corresponding rates by day 28 were 46.0% in the SP alone group, 38.2% delta-7.8%, 95% CI -17.7 to 2.1%, P 0.16 ; in the 1-dose artesunate group, and 26.0% delta20.0%, 95% CI -29.4 to -10.6%, P 0.001 ; in the 3-dose artesunate group. The artesunate and SP combination was well tolerated. There were no serious drug-related adverse events. Parasite clearance and gametocyte carriage were reduced significantly in both combination groups compared with SP alone. Three days of artesunate were required to reduce significantly the risk of treatment failure by day 28. However, the high background rate of parasitological failure with SP may make this combination unsuitable for widespread use in Kenya. 10825049 Ohrt C, Mirabelli-Primdahl L, Looareesuwan S, Wilairatana P, Walsh D, Kain KC Determination of failure of treatment of plasmodium falciparum infection by using polymerase chain reaction single-strand conformational polymorphism fingerprinting. Clin Infect Dis. 1999 Apr; 28 4 ; : 847-52. The inability to distinguish failures of treatment of Plasmodium falciparum infection from new infections is an important impediment to the evaluation of antimalarial drugs. On the basis of a pilot study utilizing polymerase chain reaction PCR ; single-strand conformational polymorphism SSCP ; analysis to genotype P. falciparum isolates, we sought to confirm that PCR SSCP analysis could reliably distinguish infections for which treatment failed from unrelated infections with a sample size adequate to estimate the accuracy of this technique. PCR SSCP analysis of the MSP-1, MSP-2, and GLURP genes was performed on 72 paired isolates recovered from 36 individuals for whom treatment failed in Thailand. In every case 100% [95% confidence interval CI ; , 90%-100%] ; , the PCR SSCP pattern of the recrudescent isolates matched that of the primary isolate. We determined whether PCR SSCP analysis could separate unrelated infections by comparing each recrudescent isolate with each of the unrelated primary isolates. Of 1, 260 comparisons, 1, 258 99.8% [95% CI, 99.4%-100%] ; were unique. The results indicate that PCR SSCP analysis can be used to differentiate infections for which treatment failed from reinfections. 16032560 Olliaro P Drug resistance hampers our capacity to roll back malaria. Clin Infect Dis. 2005 Aug 15; 41 Suppl 4: S247-57. Widespread drug resistance in parasites aggravates the burden of malaria. The extent of the problem is due mainly to the limited armamentarium of drugs used thus far to treat malaria and to policies and practices constrained by limited resources. All drugs in use are affected except, thus far, artemisinin derivatives. The scale and impact of resistance has been underestimated, leading to the continued use of failing drugs, which contributes to the rise in resistance and increased morbidity and mortality due to malaria. Pharmacological, epidemiological, and operational aspects factor the development and spread of resistance. Although the problem is complex, much can be done to reverse the course of events: adopt adequate tests to assess resistance, encourage and sustain development of new drugs, protect drugs against resistance through use of combinations, expand access to prompt and effective treatment, and promote evidence-based policies and sensible practices. The current situation favors the development of sensible strategies to restrain resistance. 11703847 Olliaro P, Taylor WR, Rigal J Controlling malaria: challenges and solutions. Trop Med Int Health. 2001 Nov; 6 11 ; : 922-7. Antimalarial drug resistance is a major public health challenge and the principal reason for the erosion of efficacious treatments. Cost and the limited number of antimalarial drugs in current use impose considerable constraints on malaria control, especially in sub-Saharan Africa. The paper describes a multilateral, multidisciplinary research project on artemisinin-based combination therapy, which offers a new and potentially highly effective way to prevent or retard the development of drug resistance. 11286794.

Kemri Wellcome Trust Research Collaborative Program, P.O.Box 43640 00100 ; , Nairobi. 2 Department of Pharmacology and Therapeutics University of Liverpool, Liverpool L693 BX. Chloroquine resistance is well established in Africa and, the synergistic antifolate fixed combination, sulfadoxine-Pyrimethamine SP ; has become the drug of choice for the treatment of uncomplicated falciparum malaria. Pyrimethamine PYR ; is a competitive inhibitor of dihydrofolate reductase DHFR ; while sulfadoxine SDX ; inhibits dihydropteroate synthase DHPS key enzymes in the biosynthesis of DNA and some proteins. Several reports have indicated that point mutations in DHFR at codon 108, 51, 59 ; [triple mutant DHFR] and in DHPS at codon 437, 540 ; [double mutant DHPS] are associated with clinical SP resistance. We sought to assess the impact of these markers in relation with clinical SP efficacy on P. falciparum samples collected in Kilifi between 19992000 as part of a broad study meant to evaluate the clinical efficacy of SPArtesunate combination. The samples were collected before treatment and within 28 days of treatment failure. Detection of the DHFR and DHPS point mutations was done using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism method. Our results showed a rise in Tp-DHFR from 54.55% before treatment to 74.36% after treatment. The same trend was observed with Db-DHPS rising from 61.70% before treatment to 88.37% after treatment. Only 2.27% Wt-DHFR was found before treatment while there was none after treatment; indicating its clearance in the course of treatment. A decrease of WtDHPS from 34.04% before treatment to 6.98% after treatment was also observed. The Tp- DHFR - Db-DHPS genotype combination the genotype strongly associated with SP resistance ; showed a substantial increase from 32.56% before treatment to 64.86% after treatment. In conclusion, our findings confirm a high selection pressure for DHFR DHPS mutations in the course of treatment with SP and that Tp-DHFR-Db-DHPS genotype combination is associated with SP resistance as previously reported and raptiva.
