This applies not only to patients with hepatitis coinfection or active drug or alcohol consumption aurogra 100 mg with mastercard, but also to black patients or patients with low CD4 T cell count when starting ART (Lohse 2007 discount aurogra 100 mg, ART-CC 2008, Harrison 2010). Even in Western countries, there remain considerable differences in the overall mortality of HIV+ patients. Higher mortality rate in North American, compared with European, may be because of the inclusion of more socially marginalized patients with higher mortality risk (May 2012). One of the most impor- tant mortality risk for HIV+ patients in industrialized countries remains still neglected: smoking. HIV+ smokers lose more life-years to smoking than to HIV. The excess mortality of smokers is tripled (Helleberg 2013). Data from prospective controlled studies on the dramatic improvement of the clinical outcome in HIV+ patients is still limited, as there have not been many randomized 6. Goals and principles of therapy 153 trials with clinical endpoints (Hammer 1997, Cameron 1998, Stellbrink 2000). The results seen in these studies, due to their design, led to the licensing of the PIs. In ABT-247, a multi-center trial, 1090 clinically advanced patients received ritonavir or placebo. The probability of AIDS and death after 29 weeks was 21. Studies of mono- or dual therapy are no longer considered ethically justifiable and the number of clinical endpoints that occur is fortunately now extremely low. As a result, the duration of any contemporary study to prove clinical benefit of one com- bination over another would have to be extended over a long period of time. Unrealistically large study populations are now required given the extremely low probability of progression – only rarely will such investigations be undertaken in the future (Raffi 2001). Two of the few trials that could confirm the benefits of ART on clinical endpoints were the SMART and the START trial (see sections 6. However, all large cohorts such as EuroSIDA, the Swiss Cohort and the US HOPS Cohort have clearly shown the benefit of ART (Table 4. The Swiss Cohort showed that the effect of ART increases over time – after more than two years on ART, the risk of disease progression was only 4% of the risk without ART (Sterne 2005). Numerous cohort studies have shown that during recent years there has been no further decline in AIDS and mortality rates. It seems that, in many patients, ART is simply begun too late. Even in 2006, almost half of the patients initiating ART have less than 200 CD4 T cells/µl (May 2006). Mortality/Morbidity each per 100 PY = patient years The effect on AIDS-defining diseases appears to be different. The most obvious is the decline in the incidence of viral OIs, although this is not as pronounced for fungal infections (D’Arminio 2005). With regard to opportunistic infections and malig- nancies, the effect of ART is equally apparent on their clinical course as it is on their incidence. Illnesses such as cryptosporidiosis or PML can be cured, while Kaposi sarcoma can resolve completely without specific therapy. Prophylaxis of pneumo- cystis pneumonia, toxoplasmic encephalitis, CMV, or MAC infection can usually be safely withdrawn at the adequate CD4 counts.

HIV Indicator diseases across Europe Study (HIDES I): Results from the Pilot Phase. Syphilis (Lues) Syphilis is caused by Treponema pallidum, a bacterium belonging to the Spirochaetaceae family. The bacteria are mainly transmitted by direct sexual contact with infected persons, and penetrate into the organism through microlesions in the mucosa or the skin. In the case of unprotected sexual contact, the risk of transmission ranges from 30 to 60%. Hematogenous or congenital trans- missions very seldomly occur in western countries. Clinical course The incubation period is usually 14 to 24 days. Approximately 40 to 50% of infec- tions show no symptoms or are self-limiting. Persistent infections may affect various organ systems, going through stages of the course of the disease. The highest risk of transmission is during the clin- ical symptomatic stages of early syphilis (primary and secondary syphilis), especially in case of a primary lesion in stage I. During the late latency period (>1–2 years after infection) and the clinically symptomatic late stages (tertiary syphilis: 2–50 years post infection) syphilis is considered to be non-infectious. Primary syphilis: 2–3 weeks after infection the primary lesion with ulcus durum (hard chancre, erosive chancre) appears at the site of inoculation. This indolent, sturdy ulcer with infiltrated borders usually yields a clear treponema-rich exudate when compressed or squeezed. The chancre is accompanied by a usually strong one- sided lymphadenitis, swelling of the lymph nodes. This primary complex will spon- taneously resolve after 4 to 6 weeks without treatment. Even an ocular involvement manifesting as episcleritis or iritis can be seen in secondary syphilis. The clinical variety of the frequent syphilids on the skin or the mucous membranes varies from exanthema (usually with palmoplantar participation) to roseola, alopecia syphilitica, moist papule, angina specifica, to condylomata lata (genital and perianal) as well as pigment changes (leukoderma specificum) and lues maligna. Headaches at night are a sign of an early syphilitic meningitis cerebrospinalis. Latent syphilis: When the infection is brought under control by the immune system the clinical features usually disappear entirely. However, during this latency period, syphilis remains serologically detectable and a relapse or progression is possible. During the early latency period (<1–2 years after infection) the syphilis can still be transmitted by blood. Tertiary syphilis: Years after primary infection, the so-called gummata may appear. These can affect any organ, showing tuberous or granulomatous changes with a ten- dency to ulceration and cicatricial healing. Major cardiovascular features of tertiary syphilis are asymptomatic aortitis, aortic insufficiency, coronary ostial stenosis and aortic aneurysm. Tertiary syphilis of the central nervous system (CNS) has many manifestations, involving the meninges and the arteries and parenchyma of the cere- bral cortex. Meningovascular syphilis is characterized by an obliterative endarteritis of the meningeal vessels with subsequent arterial thrombosis and ischemic necrosis in the brain and spinal cord. Strokes are observed even in young patients with per- sistent untreated syphilis infection. Quarternary syphilis: In untreated patients, a late neurosyphilis occurs in various forms after some years.
