Next to the type of incontin- ence it is important to determine the impact of the incontinence on the woman’s life. Obviously this is also dependent on the amount of urine lost.

    NNRTIs First generation NNRTIs Several mutations have been described with first-generation NNRTIs such as efavirenz and nevirapine buy super viagra 160 mg with amex. A single mutation can confer high-level resistance purchase 160mg super viagra otc, in particular K101P, K103N/S, V106A/M, Y181C/I/V, Y188C/L and G190A/E/Q/S for nevirapine and L100I, K101P, K103N, V106M, Y188C/L and G190A/E/Q/S for efavirenz (Melikian 2014). Contrary to V106A, V106M is seen more frequently with subtype C as with subtype B viruses (Grossmann 2004). Nevirapine or efavirenz should be stopped in the presence of mutations as the selection of further RAMs may compromise the efficacy of second generation NNRTIs. Second generation NNRTIs Etravirine is effective against variants with single NNRTI mutations like K103N, Y188L and/or G190A (Andries 2004, Vingerhoets 2010). Compared to earlier NNRTIs, etravirine has a higher genetic barrier, probably due to flexible binding to the reverse transcriptase site. In a selection experiment, the dominant viral population harbo- red, after several in vitro passages, the mutations V179F (a new variant at this posi- tion) and Y181C. Other mutations that have been selected in vitro are L100I, E138K, Y188H, G190E, M230L, and V179I (Brilliant 2004, Vingerhoets 2005). Similarly, V179F, V179I and Y181C were seen with virologic failure in the DUET studies. Further RAMs were noted at positions 101 and 138 (Tambuyzer 2010). Using a regression model and a data set of 519 geno-/phenotype pairs, 5 key mutations at 4 positions could be identified: K101P, Y181I/V, G190E and F227C. In addition, K101H, E138G, V179F and M230L proved to be relevant (Melikian 2014). In the DUET studies, 17 RAMs for etravirine were identified: V90I, A98G, L100I, K101E/H/P, V106I, E138A, V179D/F/T, Y181C/I/V, G190A/S and M230L. Based on these, an etravirine resistance score was developed. A weighting factor of 3 was attrib- uted to Y181I/V, followed by a weighting factor of 2. The mutations E138A, V106I, G190S, and V179F received a weighting factor of 1. In a panel of 4,248 NNRTI-resistant clinical HIV-1 isolates, the mutations with the highest weight, Y181I and Y181V, had a low prevalence of 1. The mutation Y181C, which is selected more frequently in patients taking nevirapine than efavirenz, had a prevalence of 32% (Vingerhoets 2008). E138A/G, V179E, G190Q, M230L and K238N received 3 points; 101E, V106A / I, E138K, V179L, Y188L and G190S received 2 points. V90I, A98G, K101H, K103R, V106M, E138Q, V179D/F/I/M/T, Y181F, V189I, G190A/E/T, H221Y, P225H, and K238T contributed with 1 point. A loss of efficacy is likely with a total score of 4 or higher (Haddad 2010). Rilpivirine is also effective against single NNRTI RAMs such as K103N, V106A, G190S/A; in vitro the following mutations were selected: V90I, L100I, K101E, V106A/I, V108I, E138G/K/Q/R, V179F/I, Y181C/I, V189I, G190E, H221Y, F227C and M230I/L (Azijn 2009). In a clinical study involving treatment-naïve patients without any (known) NNRTI mutations most of the in vitro mutations were confirmed (K101E, K103N, E108I, E138K/R, Y181C und M230L) (Molina 2008). The cross-resistance between rilpivirine and etravirine is greater than 90% (Porter 2013). Six key muta- tions at 5 positions could be identified for rilpivirine using a data set of 187 geno-/ phenotype pairs: L100I, K101P, Y181I/V, G190E and F227C. Similar to etravirine, K101H, E138G, V179F and M230L were further relevant mutations (Melikian 2014). In the Phase III studies ECHO und THRIVE, virological failure was more frequent on rilpivirine than on efavirenz (10. RAMs were more common in patients failing on rilpivirine than on efavirenz (63% versus 54%). The most common mutations were E138K (45%), K101E (13%), H221Y (10%), V189I (8%), Y181C (8%) and V90I (8%). In 46%, 31% and 23% of resistant isolates respectively, 1, 2 or 3 NNRTI mutations were detected. Overall, 15 RAMs were identified as being associated with a decreased susceptibility to rilpivirine: K101E/P, E138A/G/K/Q/R, V179L, Y181C/I/V, H221Y, F227C, M230I/L.
