Upon standard dosage EFV serum levels vary considerably in African children due to polymorphisms in the CYP2B6 drug metabolizing enzyme (Fillekes 2011) order forzest 20mg line impotence hypertension medication. Central nervous system symptoms (som- nolence buy generic forzest 20mg on line impotence over 60, insomnia order forzest master card erectile dysfunction doctor in bangalore, abnormal dreams, confusion, abnormal thinking, lack of con- centration, amnesia, agitation, depersonalization, hallucinations, euphoria) appear to be more common in adults than in children. It is rarely severe and usually disappears within days despite continuation of efavirenz. Nevirapine (NVP, Viramune) is available as immediate release tablets, as suspen- sion and as extended release tablets. Child dosing for immediate release formula- tions (body surface area BSA) is: 150–200 mg/m2 QD for 14 days (max 200 mg/day), then 150–200 mg/m2 BID (max 400 mg/day) if no rash or LFTs abnormalities; Child dosing for immediate release formulations (bodyweight) is: 4 mg/kg QD for 14 days (max 200 mg/day), then (<8 years) 7 mg/kg BID or ( 8 years) 4 mg/kg BID (max 400 mg/day) if no rash or LFTs abnormalities; Child dosing for extended-release tablets ( 3 years) (body surface area BSA) is: (0. It occurs in up to 16% of children during the first weeks of treatment, may be quite severe (8%) and require hospitalization. Antiretroviral Therapy in Children 565 Life-threatening complications (Stevens-Johnson Syndrome, toxic epidermal necrol- ysis) are rare. Hepatotoxicity may also occur, and fatal cases have been reported in adults, but this appears to be less common in children. Etravirine (ETV, Intelence) is available as 200, 100 mg tablets and 25 mg tablets through compassionate use. The AUC is decreased by 50% if it is taken on an empty stomach. Child dosing is: ( 6 years): (16–20 kg): 100 mg BID, (20–25 kg): 125 mg BID, (25–30 kg): 150 mg BID, ( 30 kg): 200 mg BID; Adult dosing is: ( 30 kg) 200 mg BID. Etravirine may be effective against HIV with some NNRTI resistance mutations, but is not used broadly due to the lack of a pediatric formulation, lack of pediatric pharmacokinetic data, lack of efficacy or safety data in children, and lack of data in antiretroviral-naïve patients. Rilpivirine (RPV, Edurant, also in Complera) is not yet licensed in children. PIs All PIs can be used in combination with 2 NRTIs. PIs differ from each other in respect to their tolerability and side effects. All PIs should be boosted with ritonavir, which increases plasma concentrations of the therapeutic PI. Lopinavir/r (LPV/r, Kaletra) is a co-formulation of lopinavir and ritonavir, in which ritonavir acts as a pharmacokinetic enhancer (booster). It is available as 200/50 mg tablets (lopinavir/r), 100/25 mg tablets or 133. There is a liquid preparation with an unpleasant taste (5 ml = 400/100 mg). Liquid has to be kept in the fridge, contains 42% ethanol 153 mg/ml and proprylene glycol and is toxic to (premature) neonates. In ART-naive and -experienced children, the combination of LPV/r and NRTI or NNRTI shows a high efficacy (Saez-Llorens 2003, Fraaij 2004). Child dosing for liquid is: (without EFV/NVP): ( 14 days (PMA >42 weeks) -6 months) 16/4 mg/kg or 300/75 mg/m2 BID, ( 6 months-18 years): 230/57. The dosage needs to be increased by up to 30% when combined with an NNRTI (TDM is useful). Cautious use is advised in patients with hepatic insufficiency. Fosamprenavir (FPV, Telzir) is available as 700 mg tablets and 50 mg/ml liquid. Liquid is given with or after food to aid palatability. Child dosing for liquid is: ( 6 years) (25–32 kg): 18 mg/kg BID+RTV 3 mg/kg BID, (33–38 kg): 18 mg/kg BID+RTV 100 mg BID, ( 39 kg) 700 mg BID+RTV 100 mg BID; Child dosing for tablet is: ( 39 kg) 700 mg BID+RTV 100 mg BID; Adult dosing is: ( 18 yrs and 39 kg): 700 mg BID+RTV 100 mg BID or (ARV-naïve) 1400 mg QD+RTV 100 mg QD. Alternatively, it can be given without RTV as booster at a dosage of 30 mg/kg BID (Fortuny 2014). Ritonavir (RTV, Norvir) is available as oral solution or capsules. Ritonavir should be exclusively used as a booster for other PIs. ATV is interesting in children because of its once-daily application and somewhat lower incidence of dyslipidemia. Child dosing is: ( 6 years) (15–20 kg): 150 mg QD + RTV 100 mg QD, (20–40 kg): 200 mg QD + RTV 100 mg QD; ( 40 kg): 300 mg QD + RTV 100 mg QD; Adult dosing is: 300 mg QD + RTV 100 mg QD. Darunavir (DRV, TMC114, Prezista) is available as 75 mg, 300 mg, 400 mg and 600 mg given with or after food and a liquid formulation. Child dosing for liquid is: ( 3 years, 10 kg): (10–11 kg): 200 mg BID+RTV 32 mg BID, (11–12 kg): 220 mg BID+RTV 32 mg BID, (12–13 kg): 240 mg BID+RTV 40 mg BID, (13–14 kg): 260 mg BID+RTV 40 mg BID, (14–15 kg): 280 mg BID+RTV 48 mg BID, (15–30 kg): 380 mg DRV BID+50 mg RTV BID, (30–40 kg): 460 mg BID+60 mg RTV BID, ( 40 kg): 600 mg BID+100 mg RTV BID; Child dosing for tablets is: ( 3 years): (15–30 kg): 375 mg BID+50 mg RTV BID, (30–40 kg): 450 mg BID+RTV 60 mg BID, ( 40 kg): 600 mg BID+100 mg RTV BID; Adult dosing is: (ART experi- enced): 600 mg BID + RTV 100 mg BID. No DRV-resistance mutations: 800 mg QD + RTV 100 mg QD. Fusion and Entry Inhibitors Enfuvirtide (T-20, Fuzeon) The drug is injected subcutaneously. Child dosing is: (6–16 yrs): 2 mg/kg BID (max dose 90 mg BID), (11. After a two-year treatment duration only 6 of 14 children stayed on this therapy (Church 2004). Reasons for treatment discontinuations were aversion to injections, local injection site reactions, inefficient viral load suppression, thrombocytopenia and edema. Maraviroc (MVC, Celsentri) is available as 150 and 300 mg tablets. In adult patients, efficacy and safety have been proven. A tropism test is required prior to the use of CCR5 antagonists. There are no data on the use of maraviroc in children. Integrase Strand Transfer Inhibitors (INSTIs) This substance class allows for new treatment options in children. Insomnia, dizzi- ness, headache, nausea and fatigue are reported in this class. As of yet, only ralte- gravir is licensed for children but studies with other INSTIs in children are under- way. Dolutegravir and elvitegravir should be very attractive as they allow for once-daily dosing. Dolutegravir (DTG, Tivicay) is a promising drug for children as it will allow once- daily regimens. Child dosing: DTG is not approved for use in neonates/infants.

Involvement of the cervix and adnexa of the uterus may cause complications like peritonitis and pelvic inflammatory disease purchase forzest 20mg mastercard erectile dysfunction age 30. Extra-genital manifestations of gonorrhea occasionally cause pharyngitis or procti- tis order forzest 20mg with visa erectile dysfunction drugs medicare. Perinatal transmission of gonococcal conjunctiva is rare cheap forzest generic erectile dysfunction pump uk. Which is why Credé’s prophylaxis for newborns (temporary treatment with eye drops: originally 1% silver nitrate solution; later, erythromycin-containing eye drops or ointments) was stopped in Germany. Systemic infections with general symptoms like fever, arthritis and endo- carditis including gonococcal sepsis are rare (Rompalo 1987). Coinfections with other STI are frequent in patients with gonorrhea (Abraham 2013). Diagnosis The most sensitive and specific detection method of Neisseria gonorrhoeae is the PCR or nucleic acid amplification test. Usually genitourethral infections are diagnosed by PCR detection in the urine. The PCR gives no information about the resistance status of the infections agent. Microscopic preparations are taken urethrally, anally, pha- HIV and Sexually Transmitted Diseases 481 ryngeally and in women also endocervically. When pus does not discharge sponta- neously out of the urethra the patient should not urinate for four hours before the urethral smear is taken. The diagnosis can be confirmed by microscopy of prepara- tions from intracellular, gram-negative diplococci using methylene-blue or gram stain. It is almost never necessary to do serological tests or immunofluorescence microscopy. Laboratory culture should be performed mainly to confirm resistance. Currently other molecular biologic methods for the detection and monitoring of resistance are being tested. Worldwide development of resistance to Neisseria gonorrhoeae is increasing with dif- ferent regional characteristics. Neisseria gonorrhoeae was found in sex workers in Indonesia (Joesef 1994), 89% of whom were penicillinase-producing and 98% of whom were resistant to tetracycline, but responded well to cephalosporins and flu- oroquinolones. At the same time, a reduced response to quinolones by up to 24% was detected in the US (CDC 1998). Penicillinase-producing (resistant) gonococcal stains are seen in the US in 25%, in Asia 30%, and in Africa up to 90%. Also an increase of resistance to 3rd generation cephalosporins has been observed in many regions (Bala 2010, Ison 2010, Chisholm 2011). Resistance to ceftriaxone has been reported (Carnicer-Pont 2012, Unemo 2011) as well as to macrolides like azithromycin (Chisholm 2009, Ison 2010). Systematic evaluation of antibiotic resist- ance in Germany has not been performed. Gonorrhea is often treated without lab- oratory culture and resistance testing. A small German study in the Heidelberg and Stuttgart regions with 65 smears from patients with uncomplicated gonorrhea during the years 2004/2005 (Enders 2006) found resistance to penicillin in 21. All iso- lates were fully susceptible to ceftriaxone, cefixime and spectinomycin, which are no longer available. Comparable results were published in Berlin from 1995 until 1997 and from northern parts of Germany from 1997–2000 (Wagner 2001, Ungeheuer 2001) looking at 85 isolates. Examinations from 2001 until 2010 in Dresden found in Neisseria gonorrhoeae-positive cultures 46% ciprofloxacin-resistant isolates but no resistance against cefotaxim or ceftriaxone (Abraham 2013). About 30% of patients with symptomatic gonorrhea are coinfected with chlamydia serotypes D-K. Therapy Therapy depends on geographical resistance profiles. With respect to fluoro- quinolone-resistant bacteria strains in Germany, a one-time IM or IV dose of 1000 mg ceftriaxone (Rocephin) (DSTIG 2013) is the treatment of choice in Germany and coadministration of a one-time dose of 1500 mg azithromycin or doxycycline 200 mg daily for seven days is recommended due to resistance of Neisseria gonor- rhoeae and frequent chlamydia coinfections.

Chlamydia infection, lymphogranuloma venereum Genital infections with Chlamydia trachomatis are nearly twice as prevalent as gono- coccal infections. There are several serotypes that can cause different diseases. Serotypes D-K are broadly distributed in Europe and cause urogenital infections, which can be sexually transmitted as well as conjunctivitis or pneumonia after peri- natal transmission.
