HIV-related Thrombocytopenia HEINZ-AUGUST HORST Thrombocytopenia is one of the most frequently observed hematological complica- tions of HIV infection. The incidence increases among patients not receiving adequate antiretroviral treatment and does not appear to vary according to the mode of acquisition of HIV (Heyward 1988, Finazzi 1990, Sloand 1992). A 10-year cumu- lative incidence of up to 45% has been reported (Eyster 1993). In patients with previously well controlled HIV infection a discontinuation of ART can lead to the rapid occurrence of thrombocytopenia (Bouldouyre 2009). Platelet counts of <30,000/µl have only been seen in less than 10% of the cases with HIV-related thrombocytopenia (Mientjes 1992, Vannappagari 2011). HIV-related thrombocytopenia has been generally attributed to two different mechanisms: First, an immunologically driven destruction of the platelets and second, an insufficient platelet production by the megakaryocytes. While in early HIV infection increased platelet destruction appears to be predomi- nant, production failure is often the main cause of thrombocytopenia in late-stage patients (Najean 1994). Table 1: Differential diagnoses of thrombocytopenia, except HIV • Pseudo-thrombocytopenia • Toxic bone marrow suppression: drugs, e. However, a spectrum of bleeding prob- lems including petechiae, epistaxis, ecchymosis, menorrhagia, hemorrhage of the gingivae may occur. Severe bleeding of the gastrointestinal tract or the CNS are rarely observed and are most likely at platelet counts <30,000/µl. In contrast to patients with immune thrombocytopenic purpura (ITP) patients often present with splenomegaly and lymph node enlargement. Spontaneous remissions of HIV-related thrombocytopenia have been observed in 10–20% of the cases, mostly with mild thrombocytopenias (Walsh 1985, Abrams 1986). Recently, the evaluation of the EuroSIDA data showed a possible association between thrombocytopenia and non-AIDS-related cancer (Borges 2014). Diagnosis HIV-related thrombocytopenia is a repeatedly confirmed isolated decrease of the platelet count <100,000/µl. In the peripheral blood the platelets often show an increased variability in size. In the bone marrow the number of megakaryocytes is normal or increased. HIV-related thrombocytopenia has to be distinguished from cases of EDTA-induced pseudo-thrombocytopenia and from other causes of “true” secondary thrombocy- topenias, which include myelotoxic drugs, hepatitis C virus (HCV), cytomegalovirus (CMV) and Mycobacterium avium complex (MAC) infections. The risk of heparin- induced thrombocytopenia is probably increased in HIV+ patients (Thompson 2007). Furthermore, the distinction from thrombotic thrombocy- topenic purpura (TTP) and hemolytic uremic syndrome is of great importance. These diseases show a peripheral platelet destruction not related to an immune mecha- nism, occur in higher frequency with HIV infection, and are life threatening. Important causes of thrombocytopenia are summarised in Table 1.
OTHER CONDITIONS CAUSING VAGINAL Urogenital tuberculosis BLEEDING Due to increasing co-infection with HIV generic 8mg zofran amex, genital This section contains incidental causes of vaginal TB is more frequently seen; previously it was quite bleeding in early pregnancy discount zofran 8mg with visa.

Subchorionic or idiopathic bleeding This can only be diagnosed if other (more serious) causes have been excluded. Idiopathic means that no specific cause can be found. In some cases the blood originates from the subchorionic area. In theory, due to growth of the uterus and its compo- nents in pregnancy, small lacerations occur below the chorionic layer and the uterine wall which presents as fresh vaginal bleeding. On direct inspec- tion using a speculum, one can clearly see blood coming straight out of the ostium of the cervix. Treatment Subchorionic or idiopathic bleeding needs reassur- ance, but no specific treatment. Sometimes subcho- rionic hematomas may lead to bothersome uterine contractions or even miscarriage. Sometimes anal bleeding is mistaken for vaginal bleeding. Usu- ally it is sufficient to ask the patient and confirm by physical examination.
In low-resource settings the patient must be referred to a specialized center zofran 8mg without a prescription. You might as well give bromocriptine as a thera- peutic trial (see below) buy 4mg zofran with mastercard. DIFFERENTIAL DIAGNOSIS AND TREATMENT See flow chart in Figure 5 cheap 4mg zofran with amex.

Appearance is typically with a painless swelling, increasing in size and even- tually pus will be expelled, but atypical signs are seen as well such as mastitis or multiple fistulae (Fig- ure 7). Treatment is according to local guidelines on tuberculosis. A patient with syphilis may also develop lesions in the breast – especially hard ulcers. Treatment is according to local guidelines (see Chapter 17 on sexually transmitted diseases). Mastodynia ‘Pain in the breast’ is present in the last week before menstruation in many women (up to 50%). This may be accompanied with nausea, headache and mood fluctuations – called premenstrual syndrome.
In African Americans cheap zofran 8mg fast delivery, rosuvastatin 10 mg lowered low- density lipoprotein cholesterol more than atorvastatin 10 mg trusted zofran 8 mg, but not atorvastatin 20 mg 8mg zofran for sale. In patients with type 2 diabetes and established cardiovascular Statins Page 26 of 128 Final Report Update 5 Drug Effectiveness Review Project disease order 8mg zofran overnight delivery, the percent low-density lipoprotein cholesterol reduction with rosuvastatin and atorvastatin was similar to that found in other studies, and patients taking rosuvastatin had greater low-density lipoprotein cholesterol reductions. Fixed-dose combination products containing a statin and another lipid-lowering drug We identified 13 randomized controlled trials comparing the low-density lipoprotein cholesterol- lowering ability of a fixed-dose combination product compared with another lipid-lowering drug in patients with baseline low-density lipoprotein cholesterol less than 250 mg/dL or 6. Of these, 10 trials involved the combination of ezetimibe and simvastatin 100-107 108 (Vytorin): 8 trials compared to another statin, 1 trial compared to fenofibrate, and 1 trial 109 compared to extended-release niacin. One trial evaluated the low-density lipoprotein cholesterol-lowering ability of the fixed-dose combination of niacin extended-release and 110 simvastatin (Simcor) to simvastatin and 2 trials evaluated the low-density lipoprotein-lowering ability of the fixed-dose combination of niacin extended release and lovastatin (Advicor) to 73, 111, 112 atorvastatin and/or simvastatin. In 7 of these trials, the percentage of patients reaching their National Cholesterol Education Program goal was also evaluated. There were 10 double- blinded and 3 open-label studies. Some had multiple arms comparing all doses of the fixed-dose combination product to equivalent doses of the statin while others compared a low dose of each without titration. In 1 trial, we only included the date of the fixed-dose combination of ezetimibe and simvastatin (Vytorin) to fenofibrate despite the trial also looking at the effectiveness of Vytorin added to fenofibrate, as this combination was 108 not fixed. All of the trials involving a fixed-dose combination of extended-release niacin with either simvastatin (Simcor) or lovastatin (Advicor) were titration studies. Two trials compared 105, 106 Vytorin to the effect of doubling the current statin dose. Similar to the statin trials, these trials included men and women ages 18 and older who met low-density lipoprotein cholesterol criteria. Most of the trials had participants complete a placebo/dietary run-in phase before determining low-density lipoprotein eligibility, although 1 compared ezetimibe and simvastatin to doubling the current statin dose after hospitalization for an acute coronary event. Most trials excluded patients with secondary hypercholesterolemia (uncontrolled diabetes, thyroid disease, or other endocrine condition), pregnant or lactating women, kidney or liver impairment, baseline creatine kinase elevation, triglycerides greater than or equal to 350 to 400 mg/dL, and those receiving drugs with the potential for drug interaction with statins. Some trials were conducted in statin-experienced patients whereas others included only statin-naïve patients. Studies varied in the baseline risk factors of their populations. Most trials were of 12 weeks duration with a range of 6 to 24 weeks. In the majority of the trials the efficacy analyses were performed on a smaller number of patients than were randomized (that is, the trials did not use intention-to-treat statistics), although most trials used modified intention-to- treat analyses requiring that at least 1 post-randomization value be available in order to include the results in the analysis. Table 6 shows the percent low-density lipoprotein cholesterol lowering from baseline for trials of a particular fixed-dose combination drug dose. Our estimates, which were based on direct active-control trials, were consistent with the information in the package insert. Ezetimibe- 103 100, 101 simvastatin fixed-dose combination was compared to rosuvastatin, atorvastatin, 102, 104, 107 105, 106 simvastatin, and doubling a statin dose. In all of these trials, participants taking Statins Page 27 of 128 Final Report Update 5 Drug Effectiveness Review Project the fixed-dose combination product had a significantly greater decrease in low-density lipoprotein cholesterol compared to those taking the statin alone. In the niacin extended release fixed-dose trials, there was no significant difference in low-density lipoprotein cholesterol 102 reduction compared to the statins except in the Bays 2003 trial which obtained 42% reduction with niacin ER/lovastatin 1000/40 mg compared to simvastatin 20 mg (34%, P<0. Percent reduction in low-density lipoprotein cholesterol with fixed-dose combination products Range of percent LDL-C lowering from Fixed-dose combination product comparative clinical dose per day trials Number of clinical trials 100-109 Ezetimibe-simvastatin (Vytorin), 10/10 mg 44. Do statins or fixed-dose combination products containing a statin and another lipid-lowering drug differ in the ability to achieve National Cholesterol Education Program goals? The ability of an agent to achieve National Cholesterol Education Program goals is another factor in choosing between statins. The Adult Treatment Panel III includes a table that is helpful in determining how much reduction is needed to achieve low-density lipoprotein cholesterol goals (see Table 7, below). The 2004 supplement to the Adult Treatment Panel III stresses that the goals are minimums.
