This case demonstrates the wide variation of clinical manifestations found in patients

Thrombotic manifestations such as serious thrombosis, TTP, and TMA usually occur in
\n late stages of chronic HIV infection or in patients with poor adherence to ART 6<\/a>]. The classic form of TTP is caused by an acquired or hereditary malfunction\/deficit
\n of ADAMTS13, which fails to cleave the ultra-large multimers of the von-Willebrand
\n factor (v-WF) and produces classic thrombotic microangiopathic anemia and multiorgan
\n failure 7<\/a>]. On the other hand, TMA associated with drugs, neoplasia, or infections has the same
\n features as classic TTP but other mechanisms lead to thrombosis without ADAMTS13 inhibition.
\n In HIV infection, multiple alterations have been described that can induce either
\n immune TTP triggered by dysfunctional ADAMTS13 or TMA generated by diverse conditions
\n such as alterations to complement proteins, endothelial injury secondary to cytokines
\n induced by the virus, or endothelial cell damage directly mediated by viral particles
\n 8<\/a>]. Because of these multiple pathological pathways, treatment of patients with either
\n TTP or TMA associated to HIV should be directed to rapidly control the viral load,
\n reduce the virus-induced immunosuppression, and replace the defective ADAMTS13 and
\n coagulation proteins by TPE.\n <\/p>\n
Miller et al<\/em>. showed that 12 % of patients diagnosed with TTP had concomitant HIV infection, and Our patient\u2019s case is remarkable in some aspects. The first and perhaps most interesting In this case, TMA was quickly controlled with TPE and prompt ART initiation.

\n they were more often found to be at advanced stages of the disease with profound immunosuppression.
\n In this situation, there was a clear therapeutic benefit of adding ART in addition
\n to TPE 9<\/a>]. However, in the largest cohort of patients, the Oklahoma Thrombotic Thrombocytopenic
\n Purpura – Hemolytic Uremic Syndrome (TTP-HUS) register, only 1.84 % of 326 patients
\n with TTP had HIV infection and the authors concluded that HIV infection, similar to
\n other inflammatory conditions, could trigger acute episodes of TTP in susceptible
\n patients. Moreover, HIV-induced oncological and infectious disorders could mimic the
\n clinical features of TTP and must be included in the differential diagnosis 10<\/a>].\n <\/p>\n
\n is that his acute HIV infection debuted with severe TMA, which to the best of our
\n knowledge has not been previously reported. Negative anti-HIV antibodies with a very
\n high HIV viral load defines acute HIV infection and is characteristically associated
\n with extremely high viremia. Our patient emphasized that sexual risk behaviors were
\n recent events (1 month), and that bleeding and constitutional symptoms appeared almost
\n immediately upon presumed HIV exposure.\n <\/p>\n
\n TPE could have had some role in our patient\u2019s recovery, information is not available
\n to support use in TMA. In this particular case, the use of TPE was an extreme action
\n given the severity of the patient\u2019s symptoms. In clinical hematology practice it is
\n well recognized that TPE is mainly beneficial in cases where TTP coexists with an
\n immune inhibitor of ADAMTS13, and not in non-immune TMA forms. However, there are
\n several recent reports showing that TPE and other immunological therapies such as
\n rituximab and eculizumab may be useful in cases not necessarily associated with autoimmunity.
\n This effect could be associated to reposition of other coagulation regulatory proteins
\n or modulation of this effect could be associatedwith reposition of other coagulation
\n regulatory proteins or B lymphocytes modulation 11<\/a>].\n <\/p>\n","protected":false},"excerpt":{"rendered":"
