    Acute HIV infection presenting as hemophagocytic lymphohistiocytosis: case report and review of the literature
    (2017-09-20) Manji, Farheen; Wilson, Evan; Mahe, Etienne; Gill, John; Conly, John
    Abstract Background Hemophagocytic lymphohistiocytosis (HLH) is an uncommon systemic inflammatory condition that can result from infections, autoimmune diseases and malignancies. It is a rarely reported life threatening complication of an acute HIV infection, with only ten documented case reports per our literature search. We present a case of HLH secondary to acute HIV infection with a negative HIV antibody-based assay and high plasma viral load. Case presentation A 45 year old male with a past medical history of well controlled hypertension presented with fever, dizziness and non-bloody diarrhea. Initial lab work revealed a new thrombocytopenia, marked renal failure and an elevated creatine kinase, ferritin, lactate dehydrogenase and D-dimer. A bone marrow biopsy revealed HLH. As part of the work up for thrombocytopenia, a rapid HIV antibody based assay was done and was negative. The sample was later routinely tested with a fourth generation antigen/antibody assay as per local protocol and was strongly positive. The plasma RNA viral load was >10,000,000 copies /mL confirming the diagnosis of an acute HIV infection. The patient was urgently started on antiretroviral therapy and recovered. Conclusion This case illustrates a diagnostic approach to HLH which is an uncommon but life threatening multisystem disease, requiring the involvement of a multidisciplinary team of experts. Following any diagnosis of HLH, rapid identification and treatment of the underlying condition is critical. A negative rapid HIV antibody test can be misleading in the context of early HIV infection and the additional use of fourth generation antigen/antibody test or plasma RNA viral load may be required within the right clinical context for diagnosis.

    Severe facial necrosis in a type 1 diabetic patient secondary to mucormycosis masquerading as an internal maxillary artery occlusion: a case report
    (2019-02-22) Manji, Farheen; Lam, John C; Meatherall, Bonnie L; Church, Deirdre; Missaghi, Bayan
    Abstract Background Mucormycosis is a group of rare but life threatening angioinvasive infections caused by fungi of the order Mucorales that often occurs in immunocompromised patients and individuals with poorly controlled diabetes. Rhinocerebral mucormycosis can mimic sinusitis but can rapidly progress to deeper disease and cause facial necrosis. Facial vascular thrombosis is a rare complication of mucormycosis and can confound diagnosis of the disease. Case presentation We report the case of a 25-year-old female with poorly controlled type 1 diabetes mellitus who initially presented with symptoms of sinusitis but rapidly progressed with signs of left-sided facial necrosis due to occlusion of the left internal maxillary artery. Early surgical debridement did not yield a microbiological diagnosis. Deeper surgical debridements ultimately revealed angioinvasive fungal disease consistent with mucormycosis. The patient recovered after repeated surgical intervention and aggressive parenteral antifungal therapy. Conclusion This case illustrates an atypical complication of mucormycosis, and emphasizes that a high index of suspicion in vulnerable patient populations aids in the diagnosis of this life-threatening infection.

    Severe Undifferentiated Vasoplegic Shock Refractory to Vasoactive Agents Treated with Methylene Blue
    (2017-10-02) Manji, Farheen; Wierstra, Benjamin; Posadas, Juan
    Methylene blue is a phenothiazine-related heterocyclic aromatic molecule presently used in the treatment of methemoglobinemia. Recently, it has been implicated in the treatment of severe refractory vasoplegic shock caused by anaphylaxis, sepsis, or postcardiopulmonary bypass. We present a case of a 27-year-old male with profound vasoplegic shock of unknown etiology which was refractory to vasopressors who responded within hours to a single dose of methylene blue. Additionally, we review the evidence of methylene blue’s role in the treatment of shock. This case illustrates a diagnostic approach and treatment options in the setting of undifferentiated vasodilatory shock and outlines a new and emerging role for methylene blue in this clinical setting.
