Venous thromboembolism occurs in 48–200 out of 1,000 patients with brain cancer per year, which is significantly more frequent than in general population.Case report. A female patient had surgical treatment of anaplastic astrocytoma following radiotherapy and chemotherapy (temozolomide, irinotecan, bevacizumab) at the age of 17 years old. She also received dexamethasone. At the age of 20 years, she developed cancer recurrence, that required chemotherapy. After chemotherapy had been initiated, the patient developed deep vein thrombosis of the legs. Rivaroxaban 20 mg/d for 2.5 months with the subsequent switch to enoxaparin 60 mg/d showed no recanalization. Enoxaparin dose increasing up to 160 mg/d demonstrated incomplete recanalization, however, superficial venous thrombosis of the legs developed. Combination therapy with enoxaparin plus warfarin resulted in further deep and superficial veins recanalization.Discussion. In cancer-associated venous thromboembolism that is resistant to low molecular weight heparin monotherapy, short-term combination therapy with low molecular weight heparin and vitamin K antagonists can be considered. However, in recurrent cancer standard treatment protocols can be ineffective.
The article is dedicated to a clinical case of the panhypopituitarism development in a patient with HIV infection receiving antiretroviral therapy. The number of HIV-infected patients worldwide has increased significantly over the past decades. The introduction of highly active antiretroviral therapy into practice has significantly improved the prognosis for these patients. At the same time, the use of this therapy type is associated with a number of complications – in particular, with the development of the immune restoration syndrome. In addition, cases of endocrine dysfunction are described in many publications. Timely diagnosis and treatment of endocrine disorders would help avoiding complications caused by excess or deficiency of hormones.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
