Ischemic Stroke as the Initial Manifestation of Neurosyphilis in a Young Adult Patient Positive for Human Immunodeficiency Virus

A 31-year-old man with pontine infarction was referred to our hospital for further evaluation and treatment. At admission, his neurological examination was unremarkable. No lymphadenopathy or skin lesions were found. The Treponema pallidum haemagglutination test, rapid plasma regain test and fluorescent treponemal antibody absorption test of immunoglobulin G were positive in both serum and cerebrospinal fluid (CSF). CSF analysis showed lymphocytic pleocytosis. The patient had male-to-male sexual contact and was found to be HIV positive. Physicians should be aware that acute ischaemic stroke may be the first manifestation of neurosyphilis in a young adult, especially with HIV infection.

Iatrogenic Cushing’s syndrome and Secondary Adrenal Insufficiency in an HIV Patientreceiving Fluticasone and Ritonavir

Objectives: To illustrate that the protease inhibitor (PI) ritonavir, widely used as part of the treatment for HIV, might cause drug–drug interactions with inhaled corticosteroids. Material and methods: A case report is presented. Results: An HIV-positive patient presented with gradually changing body composition that was ascribed to lipodystrophy. Finally, iatrogenic Cushing's syndrome with secondary adrenal insufficiency was diagnosed due to a drug–drug interaction of ritonavir and fluticasone. Conclusion: Lipodystrophy might mimic Cushing's syndrome. The combination of ritonavir and inhaled fluticasone may lead to systemic steroid excess causing Cushing's syndrome and secondary adrenal insufficiency.

Gastric and Peritoneal Involvement of Human Herpes Virus 8 Related Kaposi Sarcoma in a Patient with Acquired Immunodeficiency Syndrome

Kaposi's sarcoma (KS) is one of the most frequent neoplastic diseases in patients infected with human immunodeficiency virus (HIV). The authors report the case of a 40-year-old male with ascites, peripheral edema and peritoneal carcinomatosis secondary to a gastric KS related to human herpes virus type 8 (HHV-8). The patient had severe immunodeficiency, with a TCD4+ count of 86 cells/µl and newly diagnosed acquired immunodeficiency syndrome. His clinical condition rapidly deteriorated, with multiorgan failure, and he died without the possibility of initiating antiretroviral therapy or chemotherapy. To the authors’ knowledge, carcinomatosis is a rare feature in KS.

Fever, Hemiparesis and Hyponatraemia in a 63-year-old. HIV, another Great Masquerader?

The authors describe the unusual case of a 63-year-old patient who was referred with fever and lethargy, and was found to be hyponatraemic. The patient subsequently developed hemiparesis, and neuroradiology showed several space-occupying brain lesions. The cause was later identified as cerebral toxoplasmosis in undiagnosed Acquired Immunodeficiency Syndrome (AIDS).

Paradoxical Deterioration During Anti-Tuberculous Therapy in Non-HIV-Infected Patients with Pleural Tuberculosis: A Pragmatic Approach

We report a case of paradoxical deterioration. A male patient diagnosed with pleural tuberculosis, but who was not infected with human immunodeficiency virus (HIV), experienced clinical deterioration 3 weeks after the initiation of anti-tuberculous treatment. After other diagnoses were ruled out, a paradoxical response to treatment was established and the patient was started on systemic corticosteroids. Paradoxical response to treatment should be considered in patients with clinical deterioration after they start on anti-tuberculous treatment.
