RESUMO

Type B lactic acidosis secondary to the Warburg effect is a rare metabolic complication associated with hematological malignancies. Type B lactic acidosis occurs without tissue dysoxia due to increased aerobic glycolysis and excess lactic acid formation, commonly known as the Warburg effect. Here, we present a case of Burkitt lymphoma in a 69-year-old female with severe type B lactic acidosis and hypoglycemia that was effectively treated by the prompt initiation of chemotherapy. Type B lactic acidosis has been mostly described with hematological malignancies and rarely with solid malignancies. It is considered one of the oncological emergencies, and initiation of chemotherapy as soon as possible has been beneficial compared to alkali therapy. Lactic acidosis associated with malignancies carries a poor prognosis and high mortality.

RESUMO

Hepatitis-associated aplastic anemia (HAAA) is a rare clinical syndrome characterized by bone marrow failure 1-3 months after development of hepatitis. Untreated, hepatitis-associated aplastic anemia has poor outcome and the mainstay of treatment remains either bone marrow transplant or immunosuppressive therapy. A previously healthy 21-year-old man presented with a 1-week history of right upper quadrant pain and jaundice. Admission labs revealed mixed hyperbilirubinemia and elevated transaminases ranging in 2000s IU/dl. Extensive workup for etiologies of acute hepatitis including viruses, autoimmune, toxins etc. were negative. He admitted to taking "Dust V2," a workout supplement, for 4 months prior to the presentation. His liver function tests started to improve after conservative treatment. Two months after his discharge, he was found to have severe pancytopenia on routine labs. Bone marrow biopsy revealed hypocellular marrow consistent with aplastic anemia. Extensive workup for etiologies of aplastic anemia were negative. On literature review, none of the components of the supplement were found to cause aplastic anemia. A diagnosis of hepatitis-associated aplastic anemia was made as there was a lag time before development of anemia. His counts failed to improve despite treatment with filgrastim and he was referred for hematopoietic cell transplant.

RESUMO

Catastrophic antiphospholipid syndrome (CAPS) is a rare but severe form of antiphospholipid syndrome (APS). The syndrome manifests itself as a rapidly progressive multiorgan failure that is believed to be caused by widespread micro-thrombosis. Seldom does bleeding comanifest with thrombosis. We present a patient with APS who presented with nausea, vomiting and fatigue, and rapidly progressed into multiorgan failure before being diagnosed with CAPS. The clinical course was complicated by an atraumatic intracranial haemorrhage which demanded discontinuation of anticoagulation. The patient was treated with high dose steroid, intravenous immunoglobulin, followed by weekly rituximab infusion. Although the trigger for CAPS was not obvious during her hospital stay, she was diagnosed with acute cytomegalovirus (CMV) infection soon after discharge. In this case report, we explore the differential diagnoses of CAPS, investigate the possibility of CMV infection as a potential trigger, present the therapeutic challenges of anticoagulation and discuss the emerging use of rituximab.

RESUMO

Buschke-Löwenstein tumor of anorectal and perianal area is a rare but highly aggressive tumor, frequently associated with human papillomavirus (HPV) types 6 and 11. It often grows over years in immunocompetent patients and can be highly destructive to local tissue. We present a case of a 61-year-old male with HIV infection who presented with worsening pain and swelling in the anorectal area for one-year duration. Exam revealed a 15 × 10 cm mass in the anorectal area with multiple sinuses and fistulas. MRI revealed extension of the mass through pelvic structures. Biopsy showed squamous epithelium with koilocytes and histochemistry positive for P16, suggestive of HPV infection. Biopsy was negative for malignant transformation. He was not a candidate for surgery or radiation due to extensive infiltration of deeper structures and multiple fistulas. He refused interferon therapy, and diverting colostomy was placed for palliation. He presented two months later with overwhelming sepsis and died despite maximal medical therapy.

RESUMO

BACKGROUND: Acute myeloid leukemia (AML) is a heterogeneous malignancy with diverse genetic abnormalities, clinical presentations, and outcomes. Known predictive and prognostic factors in AML include age, performance status, comorbidities, cytogenetics, and molecular mutations. Identifying prognostic and predictive factors can inform the choice of induction therapy and outcomes prediction. PATIENTS AND METHODS: A retrospective review was performed of 137 adult AML patients from 2010 to 2015. Predictors of complete remission (CR) and overall survival (OS) were determined for patients treated with 3+7 (3 days of anthracycline and 7 days of cytarabine) or hypomethylating agent. Variables associated with CR or OS were assessed using univariate Cox regression and a multivariate Cox model. RESULTS: The average age was 65 years and 91 patients (66%), sample size is 137 patients had primary AML. Patients in the 3+7 induction group were younger, had a higher bone marrow blast percentage, and more de novo AML compared with those in the hypomethylating agent group (P < .001, P < .001, P = .005, respectively). Univariate logistic regression for CR showed a significant association between age (P < .001), choice of induction (P < .001), and monosomy (P = .015), although only induction with 3+7 (P < .001) and absence of monosomy (P = .042) remained significant in multivariate analysis. Univariate Cox regression indicated that age (P = .003), AML status (de novo or secondary; P = .0277), choice of induction (P = .030), and monosomy (P = .010) had a significant association with OS. Only younger age (P = .018) and absence of monosomy (P = .022) were predictive of OS in multivariate Cox analysis. CONCLUSION: Positive predictors of CR in adult AML include absence of monosomy and induction treatment with 3+7; whereas positive predictors of OS are younger age and absence of monosomy.
