The UI prevalence of Taiwanese women is high, and its negative effects on quality of life are greater than those of other major chronic conditions, but are often overlooked and seldom intervened.

The purpose of this study was to investigate the effect of a symptom management program on self-care of medication side effects among AIDS/HIV-positive patients. Sixty-seven patients from a sexually transmitted disease control center, a medical center, and a Catholic AIDS support group in Taipei were randomly assigned to three groups: one-on-one teaching, group teaching, and a control group. All subjects in each teaching group attended a 60- or 90-minute program on highly active antiretroviral therapy (HAART) side effect self-care education and skill training once per week for 3 weeks; subjects also underwent counseling by telephone. A medication side effect self-care knowledge questionnaire, Rosenberg's Self-Esteem Scale (RSES), and unscheduled hospital visits were used to evaluate the effectiveness of the symptom management program. The results revealed there were significant differences in mean difference of knowledge and unscheduled hospital visits between baseline and post-testing at 3 months for symptom management in the two groups. The mean difference of the self-esteem scale was not significant between the two groups. In summary, the symptom management program effectively increased the ability of AIDS/HIV-positive patients to self-care for medication side effects. We recommend that this program be applied in the clinical nursing practice.

Needle-sharing and sexual contact are important transmission routes of hepatitis B, C, and D virus (HBV, HCV, HDV) infection. This study aimed to investigate the current status of these viral infections among high-risk populations including prostitutes and intravenous (i.v.) drug users, compared with the prevalence rate reported previously to examine the changing seroepidemiology. Of the 916 female prostitutes, 79 (9%) were positive for antibody to HCV (anti-HCV), 111 (12%) were positive for HBV surface antigen (HBsAg), and 5 (5%) had antibody to HDV (anti-HDV). The prevalence rate was significantly lower compared to that in 1989-1991 (12%, P = 0.037) for HCV infection, and to that in 1988 (59%) and 1996 (40%) (P < 0.0001) for HDV infection. Of the 494 i.v. drug users, 87 (18%) patients were HBsAg carriers and 12 (14%) were anti-HDV-positive. The prevalence rate of HDV infection was significantly lower than that reported in 1985 (79%, P < 0.0001). Among the 443 tested i.v. drug users, 182 (41%) were anti-HCV-positive, significantly lower than that in 1985 (53%, P = 0.026). Of the 263 male prostitutes, 11 (4%) were anti-HCV-positive, 45 (17%) were HBsAg-positive, and 7 (16%) were anti-HDV-positive. Of the 129 illegal immigrant prostitutes, 7 (5%) were anti-HCV-positive, 15 (12%) were HBsAg-positive and none were positive for anti-HDV. In conclusion, the findings indicate a declining prevalence of HCV and HDV infections among drug users and prostitutes over the past 16 years. Male prostitutes and immigrant prostitutes are new "high-risk" populations and may become a reservoir for disease transmission.

Human immunodeficiency virus type 1 (HIV-1) Vpu protein promotes both extracellular release of viral particles and degradation of CD4 in the endoplasmic reticulum. The correlation of anti-Vpu antibody (Ab) reactivity to Vpu and AIDS disease progression was studied in 162 HIV-1/AIDS patients after they had received highly active antiretroviral therapy (HAART) for 1 year. Anti-Vpu Ab reactivity was analyzed by Western blot using a recombinant Vpu protein. Results showed that at baseline (prior to initiation of HAART), 31.5% of patients (51/162) had anti-Vpu Ab. The proportion of anti-Vpu Ab in patients with CD4 counts > or =500, 200-500 and <200/mm(3) were 40.6, 34.7 and 14.3%, respectively (chi(2) test, p < 0.05). In addition, decreasing levels of anti-Vpu Ab reactivity were significantly correlated with increasing levels of HIV-1 viral load. After receiving HAART for 1 year, 7 of 111 anti-Vpu Ab-negative patients (6.3%) seroconverted (- --> + group) and 8 of 51 anti-Vpu Ab-positive (15.7%) patients became negative (+ --> - group). Among 104 anti-Vpu Ab-negative patients, 40 were selected for analysis of the VPU gene. All of them had an intact VPU gene. Patients were further divided into four groups according to their anti-Vpu Ab serostatus and anti-HIV-1 Ab was measured. The results showed that only the anti-Vpu Ab seroconverted group (- --> +) had increased serum levels of anti-HIV-1 Abs after 1 year of HAART, while the other three groups (+ --> +, - --> - and + --> -) had decreased serum levels of anti-HIV-1 Abs after 1 year of HAART (p < 0.05). In conclusion, the presence of anti-Vpu Ab is associated with improved prognosis following HIV-1 infection, and seroconversion of anti-Vpu Ab in patients on HAART indicates significant recovery of immunity.
