Severe bleeding of the gastrointestinal tract or the CNS are rarely observed and are most likely at platelet counts <30 generic 10mg enalapril,000/µl quality 10mg enalapril. 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. Therapy The therapy is based on two principles: antiretroviral therapy, and in severe cases an additional treatment with agents used in non-HIV immune thrombocytopenia, i. In refractory cases splenectomy is also a treatment option (George 1996, Godeau 2007). The treatment besides ART is based on the recent international consensus report and the guidelines of the American Society of Hematology (Provan 2010, Neunert 2011). Table 2: Therapy of HIV-related thrombocytopenia Clinical Situation Therapy Asymptomatic and ART thrombocytes >30,000/μl Thrombocytes <30,000/μl or ART plus thrombocytes <50,000/μl and First-line therapy: glucocorticoids significant mucous membrane bleeding Subsequent therapies*: intravenous immuno- globulins, anti-(Rh)D, rituximab, splenectomy Severe bleeding Platelet transfusions, high-dose glucocorticoids, intra- venous immunoglobulins, either alone or in combination * Subsequent therapies after failure of glucocorticoids should be given according to the experience of the treating physician since only a few prospective randomised studies are available (Vesely 2004) ART: leads to a significant recovery of the platelet count within three months of treatment in most patients (Arranz Caso 1999, Servais 2001). This effect is independent of the antiretrovirals utilised and the platelet count at the start of therapy (Arranz Caso 1999). Importantly, during treatment interruptions often thrombocytopenias develop, particularly in patients with a history of HIV-related thrombocytopenia (Ananworanich 2003, Bouldouyre 2009). A therapy in addition to ART is indicated for patients with a platelet count <30,000/µl or a platelet count of <50,000/µl with a significant concomitant mucous membrane bleeding or risk factors for bleeding, such as peptic ulcers or hypertension (George 1996). Glucocorticoids: are currently the standard first-line therapy of HIV-related throm- bocytopenia. After a response, which can be expected within a few days, the initial dose should be continued for 3-6 weeks. Then, depending on the platelet count, which should be kept >60,000/µl, the glucocorticoid dose should be tapered within weeks and discontinued if possible. In the case of a life-threatening bleed we recommend higher dosages (i. In order to avoid a long-lasting therapy with prednisolone or prednisone and possible side effects, a short-term protocol with high- dose dexamethasone may be used. After treatment with 40 mg of dexamethasone HIV-related Thrombocytopenia 609 for four consecutive days in patients with non-HIV immune thrombocytopenia a response can be seen in 85% of patients. A relapse does occur in 50% of the respond- ing patients within six months. These patients require a prolonged therapy with glucocorticoids or a different treatment (Cheng 2003). After four cycles of dexam- ethasone given for four days every 14 days in 74% of the patients a long-term response (median time of 8 months) can be seen (Mazzucconi 2007). Using steroids it has to be kept in mind that particularly prolonged treatment is associated with a high risk of even fatal infectious complications (Portielje 2001, Zimmer 2004). Intravenous immunoglobulins: are costly and often given after failure of gluco- corticoids, in the case of contraindications against glucocorticoids or in a situation with life-threatening bleeding. The standard dose is 1 g/kg body weight for 1–2 days. Without maintenance therapy the platelet count will decrease in most patients and it drops to the pre-treatment levels after about a month (Godeau 2007). Anti-(Rh)D: The intravenous anti-(Rh)D application is an interesting treatment option. The mechanism of action is assumed to be mediated through the destruc- tion of antibody-coated (Rh)D positive red blood cells (RBC). The preferential clear- ance of antibody-coated RBC by macrophages particularly in the spleen leads to an Fc receptor blockade sparing the destruction of autoantibody-coated platelets (Scaradavou 1997).
