Sidonio, Jr2 1Departments of Medicine and Pathology, Microbiology & Immunology and 2Department of Pediatrics, Hemostasis & Thrombosis Clinic, Vanderbilt University, Nashville, TN VWD is the most common inherited bleeding disorder known. It is caused by a deﬁciency or dysfunction of the VWF molecule. Bleeding risk varies between modest increases in bleeding seen only with procedures to major risk of spontaneous hemorrhage depending upon the type of VWD. The treatment approach to VWD has changed little in the past 2 decades, but there are numerous subtleties in optimal management. Management includes the prevention or treatment of bleeding by raising endogenous VWF levels with medications such as desmopressin or providing exogenous VWF concentrates. Fibrinolytic inhibitors and topical hemostatic agents are also effective adjunctive measures. Bleeding speciﬁc to women presents a special challenge because of heavy menstrual bleeding and pregnancy. Successful management of pregnancy in patients with VWD involves coordination with obstetrics, anesthesia, and the coagulation laboratory monitoring VWF:RCo and FVIII:C levels. Prophylactic treatment with VWF concentrates is emerging as an effective preventive therapy in patients with severe disease. Antibodies to VWF present a special challenge in the management of rare patients with type 3 disease. New therapies on the horizon include recombinant VWF, anti-VWF aptamers, and medications such as IL-11 to raise VWF levels. The key to effective treatment of VWD is an accurate diagnosis of the speciﬁc type and selection of hemostatic products appropriate for the clinical situation. These deﬁnitions can be arbitrary and responses may not be adequate for all clinical situations. It is important to perform a Introduction trial with a standard DDAVP dose administered intravenously, VWD is an inherited autosomal disorder of deﬁcient (type 1 or 3) or subcutaneously, or intranasally after baseline levels of VWF:Ag, dysfunctional (type 2 variants) VWF. It is characterized primarily VWF:RCo, and FVIII:C are drawn to document the patient’s by mucocutaneous bleeding, excessive hemorrhage after invasive adequate responsiveness before using the drug in a speciﬁc bleeding procedures, and, less commonly, by soft tissue hematomas and joint 1 situation.
Side effects resemble those of retinoid therapy: alopecia effective 200 mg doxycycline antibiotics and milk, dry skin and lips buy 200mg doxycycline with mastercard treatment for uti other than antibiotics, and ingrown nails. Many patients also develop asymptomatic hyperbilirubinemia. Although it seems that the dose and toxicity can be reduced by TDM (Wasmuth 2007), indinavir does no longer play a role. Lopinavir/r (LPV, Kaletra) was licensed in April 2001 and is so far the only PI with a fixed boosting dose of ritonavir. This increases concentrations of lopinavir by more than 100-fold (Sham 1998). In 2006, the old Kaletra capsules were replaced by tablets, allowing a pill reduction (Gathe 2008). Lopinavir is still the most frequently prescribed PI worldwide and has also been licensed as once-daily since 2009 after several studies showed efficacy and tolerability (Molina 2007, Gathe 2009, Gonzalez- Garcia 2010). However, other studies found a slightly reduced potency of QD dosing 6. Overview of antiretroviral agents 95 (Ortiz 2008, Flexner 2010). Lopinavir QD is therefore only recommended if the number of PI resistance mutations is low. In treatment-naïve patients, lopinavir/r was significantly superior to an unboosted regimen with nelfinavir (Walmsley 2002). However, more recently, large randomized trials such as KLEAN, GEMINI, ARTEMIS and CASTLE have shown that there are no significant differences compared to boosted PIs such as fosamprenavir/r (Eron 2006), saquinavir/r (Walmsley 2009), or atazanavir/r (Molina 2008). In ACTG 5142, lopinavir/r was inferior to efavirenz (Riddler 2008), possibly due to lower tolerability. In treatment-experienced patients, lopinavir/r showed slightly better results than boosted saquinavir (the old Fortovase formulation) in an open-label randomized trial (MaxCmin2) on a heterogeneous population of treatment-experienced patients. This was particularly true for tolerability, but also with respect to treatment failure (Dragstedt 2005). On the other hand, in two smaller studies in PI-experienced patients, virologic efficacy of lopinavir/r was not significantly higher than that of boosted atazanavir (Johnson 2006) or fosamprenavir (Elston 2004). In comparison to darunavir, efficacy was even lower (Madruga 2007, De Meyer 2009). Development of resistance in first-line is rare, but is theoretically possible (Kagan 2003, Conradie 2004, Friend 2004). Lopinavir/r has a high genetic barrier to resistance, and it is likely that at least 6-8 cumulative PI resistance mutations are necessary for treatment failure (Kempf 2002). That is why lopinavir is also considered for monotherapies (see below). A significant concern with lopinavir are the gastrointestinal side effects (diarrhea, bloating) which are probably more frequent on a once-daily dosage (Johnson 2006). In addition, lipodystrophy and often considerable dyslipidemia, have been observed, probably more marked than with atazanavir (Molina 2008, Mallolas 2009), darunavir (Mills 2009) and saquinavir (Walmsley 2009), but not more so than with fosampre- navir (Eron 2006). The dose must be increased in combination with efavirenz and nevirapine, probably also with concurrent administration of fosamprenavir. Nelfinavir (NFV, Viracept) was the fourth PI on the market. Due to high pill burden, diarrhea and a lower antiviral potency, nelfinavir no longer plays much of a role in HIV treatment. Ritonavir (RTV, Norvir) was the first PI for which efficacy was proven on the basis of clinical endpoints (Cameron 1998). However, ritonavir is now obsolete as a single PI, since tolerability is poor. As gastrointestinal complaints and perioral paresthesias can be very disturbing, ritonavir is now only given to boost other PIs. The “baby dose” used for this purpose (100 mg QD) is better-tolerated. Ritonavir inhibits its own metabolism via the cytochrome P450 pathway. The potent enzyme induction results in a high potential for interactions. Many drugs are contraindicated for concomitant administration with ritonavir. Metabolic disorders probably occur more frequently than with other PIs. Caution should be exercised in the presence of impaired liver function. It is no longer necessary to store ritonavir at cool tempera- tures thanks to the Meltrex formulation that came onto the market in 2010. Saquinavir (Invirase 500), previously Invirase, Fortovase, was the first HIV PI to be licensed in December 1995, and is still one of the few agents with efficacy based on clinical endpoints (Stellbrink 2000). Boosting with ritonavir raises the plasma level sufficiently, as does simultaneous food intake, so saquinavir should be taken with meals. The hard gel (Invirase) and soft gel (Fortovase) capsules were replaced in 2005 by Invirase 500 tablets, which significantly reduced the number of pills to six a day (including ritonavir boosting). The GEMINI trial compared ritonavir- 96 ART boosted Invirase 500 tablets to lopinavir/r in 330 ART-naïve patients who all received TDF+FTC. There were no significant differences with respect to efficacy at 48 weeks (Walmsley 2009). Some adverse effects such as lipid elevations were less pronounced with saquinavir, as was diarrhea. However, discontinuation rates due to adverse events were comparable between arms. During recent years, several warning letters were published, regarding QT prolongation and the need for ECG monitoring with saquinavir. Treatment naïve patients should be started on a reduced dose of 500 mg BID for the first seven days, before increasing to the standard dose of 1000 mg BID (always in conjunction with ritonavir 100 mg BID). In addition to baseline, the ECG should now be performed after approximately 10 days of treatment. Thus, it is difficult find any reason for starting saquinavir. Tipranavir (TPV, Aptivus) is the first non-peptidic PI licensed in Europe in July 2005 for treatment-experienced patients. As oral bioavailability is only moderate, double the standard ritonavir boosting (McCallister 2004) is necessary, so 2 x 200 mg (BID) has to be used. The plasma levels can also be increased by a high fat meal.
However purchase cheap doxycycline on line antibiotic journal articles, there are some newer studies that show an increase of inflammatory or coagulation parameters during therapy interruption (Kuller 2008 buy doxycycline us antibiotics for acne control, Calmy 2009, Baker 2011, Olmo 2012). Cystatin C, a parameter for renal dysfunction, also increases (Mocroft 2009). Especially the argument that therapy interruptions improve quality of life is no longer the case. One can discuss higher values for initiation and interruptions, but there will certainly not be any second SMART with new starting/stopping values for some time. Patients should always be encouraged to continue ART. Thanks to the new classes, the options have widened, enabling us to respond to side effects. If the patient, after discussion, still wishes to interrupt therapy the wish should be respected. The inter- ruption will happen anyway with or without the doctor’s agreement. A monitored interruption is better than one done secretly behind the physician’s back. Under strict surveillance the risk for complications is rather low, but again, the patient should consider the possibilities of changing treatment vs leaving it. Practical tips for treatment interruptions • If there are no problems with ART, there is no reason to stop it. A supervised treatment inter- ruption is better than one undertaken without the awareness of the clinician. References Ananworanich J, Kerr SJ, Vernazza P, et al.
