Two Cases of Cerebral Toxoplasmosis in AIDS Patients / 대한내과학회지

Toxoplasmosis of the central nervous system occurs in 3 to 40 percent of all patients with the acquired immunodeficiency syndrome (AIDS), and it is the most common opportunistic infection to cause encephalitis or focal intracerebral lesions. We experienced two cases of cerebral toxoplasmosis in AIDS patients presenting as high fever, seizure and general weakness.

A Case of Cutaneous Extramedullary Hematopoiesis in Idiopathic Myelofibrosis / 대한혈액학회지

Idiopathic myelofibrosis is characterized by replacement of the bone marrow with fibrous tissue and the development of extramedullary hematopoiesis. The latter involves mainly the spleen and liver but also occurs in lymph nodes, kidneys, retroperitoneal fat, and more rarely, the skin. We report a 48-year-old male with idiopathic myelofibrosis who was admitted due to numerous papules and nodules on his trunk. The skin lesions were histologically defined as cutaneous extramedullary hematopoiesis.

The Clinical Study of Hematoimmunologic Features and Opportunistic Infections of Patients with AIDS / 대한내과학회지

The number of persons with HIV infection in Korea have increased steadily, total number of HIV infection in Korea were 478 on August, 1995. To investigate the clinicoimmunologic manifestation of AIDS in Korea, we reviewed complete blood counts (CBC), CD4 counts, serum beta2-microglobulin level, opportunistic infections and cause of death for 19 AIDS patients who had been admitted or visited at Pusan national university hospital during the period of January, 1990 to August, 1995. 1) The predominant mode of HIV transmission was heterosexual contact(18), other modes of transmission were homosexual contact(1). Clues of diagnosis of HIV infection were routine occupational health examination(14), and opportunistic infection symptoms such as fever, coughing(4). 2) Mean CD4 cell counts(/mm3) were 53 +/- 72 totally, 22 +/- 27 for 8 dead patients at mean 2 month before, 91 +/- 87 for 7 living patients. There were not significant difference(p>0.05). 3) Serum beta2-microglobulin(MG;ug/ml) was measured at 12 patients, mean serum beta2-MG level was4.8 +/- 7.3 totally, 7.1 +/- 10.3 for 6 dead patients at mean 1.3 month before, 2.5 +/- 0.4 for 6 living patients. There were not significant(p>0.05). 4) At CBC examination, WBC(/mm3) was 5,932 +/- 2,899 totally, 5,452 +/- 3,436 for 10 dead patients, 6,500 +/- 2,221 for 9 living patients(p>0.05). Hb(g/dl) was 11,4 +/- 2.8 totally, 9.4 +/- 1.8 for dead patients, 13.6 +/- 1.8 for living patients(p<0.05). Lymphocyte count(/mm) was 1,255 +/- 800 totally, 731 +/- 424 for dead patients, 1,838716 for living patients(p<0.05). ESR(mm/h) was 72 +/- 47 totally, 97 +/- 33 for dead patients, 47 +/- 47 for living patients(p<0.05). 5) Opportunistic infections had developed at 14 patients, candidiasis 7, pneumocystis carinii pneumonia 5, tuberculosis 3, cytomegalovirus infection 2, herpes zoster 3, toxoplasmosis 1, cryptococcal infection 2, bacterial pneumonia 5, and herpes simplex l. Malignant lymphoma had developed in 1 patient. 6) Mean survival interval from diagnosis of HIV infection to death was 32.8 +/- 19.1 months, and the most common cause of death was pneumocystis carinii pneumonia, and other causes of death were meningitis, bacterial pneumonia and AIDS-wasting syndrome. Based on these results, We concluded that CD4 counts, serum beta2-microglobulin level, Hb, total lymphocyte count and ESR in AIDS patients are specific laboratory markers of progression and prognosis of AIDS, the most common opportunistic infection was candidiasis, and the most common cause of death in AIDS patients was pneumocystis carinii pneumonia.
