Pharmacotherapeutic group: nucleoside analogue, ATC Code: JO5A F30 Lamlvudine and zidovudine are nucleoside analogues which have activity against HIV. Additionally, lamivudine has activity against hepatitis B virus HBV ; . Both medicinal products are metabolised intracellularly to their active moieties, lamivudine 5'- triphosphate TP ; and zidovudine 5'triphosphate respectively. Their main modes of action are as chain terminators of viral reverse transcription. Lamivudine-TP and zidovudine-TP have selective inhibitory activity against HIV-1 and HIV-2 replication in vitro; lamivudine is also active against zidovudine-resistant clinical isolates of HIV. Lamivudind in combination with zidovudine exhibits synergistic anti-HIV activity against clinical isolates in cell culture. HIV-1 resistance to lamivudine involves the development of a M184V amino acid change close to the active site of the viral reverse transcriptase RT ; . This variant arises both in vitro and in HIV-1 infected patients treated with lamivudine-containing antiretroviral therapy. M184V mutants display greatly reduced susceptibility to lamivudine and show diminished viral replicative capacity in vitro. In vitro studies indicate that zidovudine-resistant virus isolates can become zidovudine sensitive when they simultaneously acquire resistance to lamivudine. The clinical relevance of such findings remains, however, not well defined. Cross-resistance conferred by the M184V RT is limited within the nucleoside inhibitor class of antiretroviral agents. Zidovudine and stavudine maintain their antiretroviral activities against lamivudine-resistant HIV-1. Abacavir maintains its antiretroviral activities against lamivudine10.

The hazard ratio HR ; was 0.427 95% CI, 0.318 to 0.572 ; or a 57% reduction in risk. In addition, the data indicated a significant reduction in death, regardless of causality, in the combination lamivudine plus zidovudine containing regimens as compared to the zidovudine containing regimens alone p 0.0007 HR 0.399 95% CI, 0.230 to 0.693 ; or a 60% reduction in risk. ACTG320 was a randomised, double blind, placebo controlled study to compare indinavir, zidovudine or stavudine ; and lamivudine with the two drug regimen of zidovudine or stavudine ; and lamivudine in HIV infected patients with CD4 counts less than or equal to 200 cells mm 3. Patients had received greater than or equal to three months prior zidovudine therapy and crestor. Other regimens with either drug plus a placebo all regimens still had dual NRTIs ; . Also, subjects in the efavirenz or nevirapine arms with viral loads less than 50 copies mL at week 16 had significantly shorter times to viral loads greater than 200 copies mL than subjects in the efavirenz plus nelfinavir arm. Abstract 531. ; Salvage therapy: a very rocky road. Several investigations grappled with the dilemma of salvage therapy. A study from Europe Abstract 539 ; found that patients starting a second protease inhibitor containing regimen experienced greater success if the second regimen was initiated at a lower viral load or higher CD4 T cell count, or if new NRTIs were added. Several conclusions came out of a late breaker report on ACTG 398 Abstract LB7 ; : only 34% of patients achieved viral loads below 200 copies mL despite implementing 4-5 new agents, dual protease inhibitor regimens were more successful than single protease inhibitor regimens, and previous NNRTI experience was significantly associated with treatment failure while previous protease inhibitor experience was not. Also, a study in amprenavir experienced patients 64% monotherapy, 32% with lamivudine and zidovudine, 4% with other regimens ; found that a majority of subjects who switched to a 4-drug regimen indinavir nevirapine stavudine lamivudine ; had suppressed viremia less than or equal to 500 copies mL ; for up to 48 weeks Abstract 526 ; . Finally, a Canadian group reported preliminary results of sustained antiviral responses less than or equal to 400 copies mL ; in 40-50% of heavily pretreated patients at up to weeks under multidrug rescue therapy, where up to 9 drugs were used. Clearly, such treatments present difficulties with adherence and toxicity. Non-nucleoside viral susceptibility. A study investigating why NNRTI containing regimens perform well as "salvage" therapy in NRTI experienced patients found a significant correlation between NRTI resistance and NNRTI susceptibility. Increased viral susceptibility to NNRTIs delavirdine, efavirenz, and nelfinavir ; was seen in greater percentages of NRTI expe.Obstetrical Delivery Contraindications Precautions: 1.

Thing there was to know about epilepsy. Out of sheer desperation, they decided to come to the S.E.E. program anyway. Attending the program wasn't easy. They had to find someone willing to baby sit a four-year-old having 40 seizures a day for four days. Most parents would have given up right there, but not Robin and Wayne. They needed the sitter for four days because the nearest S.E.E. program was a 12-hour drive from their home. They needed an extra day for travel each way. The S.E.E. program surprised them. Within minutes they were astonished to find how little they actually knew despite years of medical treatments. They learned about the many kinds of epilepsy, the latest diagnostic procedures, and about a whole range of treatments. They learned about medications and about controlling side effects. Most of all they discovered there were things they could do right now to help Ashley. On the long drive home they worked out a plan. Now that they understood how comcontinued on page 4.
To treat lamivudine-resistant mutants would be considerably higher than that used for wild-type HBV. L-D4FC and L-FMAU were effective against single Bor C-domain mutants L528M and M552V with an EC50 of less than 2 M, but were ineffective against the double mutant L528M M552V, with an EC50 exceeding 10 M. In addition, the EC50 of entecavir for the double mutants was about 500 times higher than that for the single B-domain mutant L528M, and 90 times higher than that for the single C-domain mutants. The addition of the B-domain mutation L528M to C-domain mutants may contribute to increased levels of resistance to entecavir, L-D4FC, and L-FMAU but does not seem to increase the level of resistance to adefovir, suggesting that the resistance pattern for adefovir is unique and different from those of entecavir, L-D4FC, and L-FMAU. Although further studies are needed to address the cytotoxicity of these drugs in humans, the doses of the compounds used in our study are far below the toxic doses reported by others. Using 2.2.15 cells, no apparent cytotoxicity was noted at concentrations greater than 1, 000, 150, and 30 M for lamivudine, adefovir, and entecavir, respectively 34, 45, 46 ; . For L-D4FC, the concentration required to inhibit 50% of HepG2 growth was estimated to be 20 Unfortunately, L-D4FC is cytotoxic in various cells and with prolonged treatment has been shown to increase lactic acid production in HepG2 47 ; . L-FMAU ; -FTC, and ; FTC did not show any cytotoxicity up to 200 M in 2.2.15 cells 3638 ; . In addition, with the exception of entecavir, in vivo studies have shown that these compounds are not associated with overt toxicity at high doses 100 mg kg ; . In duck hepatitis B virusinfected ducklings, treatment with 1530 mg kg of adefovir or 40 mg kg of L-FMAU produced no toxic side effects 46, 48 ; . In the woodchuck model, 0.50.1 mg kg of entecavir, 14 mg kg of L-D4FC, or 2030 mg kg of ; -FTC inhibited replication of woodchuck hepatitis virus without associated toxicity 4952 ; . As learned from the treatment of HIV, it is likely that combinations of HBV drugs should be used to maximize suppression of replication and consequently decrease the probability of the emergence of a drugresistant virus 40, 53, 54 ; . This approach would permit the use of lower doses of the antiviral agents and, therefore, reduce the likelihood of side effects. It also seems advantageous to combine adefovir with lamivudine, entecavir, L-D4FC, L-FMAU, or ; -FTC in an effort to better suppress HBV replication and delay the development of resistance. Although entecavir, L-D4FC, and L-FMAU had the lowest EC50, a combination of these three drugs may be compromised, as they have a similar cross-resistance profile. Further studies are necessary to determine the potential synergistic interaction of compounds in combination therapy.
