ABSTRACT
INTRODUCTION: To achieve the Sustainable Development Goals (SDGs) target 2030, the United Nations (UN) endorsed tobacco use reduction, which is essential in decreasing unnecessary deaths caused by tobacco-induced disease. This study investigates the association between tobacco use and Human Papillomavirus (HPV) infection in clinically normal uterine cervix populations from the SDGs perspective. METHODS: This study is a 7-year cross-sectional study of a clinically normal uterine cervix population, based on negative Visual Inspection of Acetic Acid (VIA). Subjects were recruited consecutively from the medical records of several public and private health providers in Jakarta. The Statistical Product and Service Solutions (SPSS) for Windows version 20.0 were used to analyze the data. RESULTS: A total of 1397 negative VIA subjects were collected, consisting of 4.9% (69/1397) tobacco users, and 95.1% (1328/1397) non-users. HPV-DNA positive were 4.3% (3/69) in the tobacco user group and 3.7% (49/1328) in the non-user group. Statistical analysis showed unadjusted OR was 1.19 (95% CI: 0.36-3.91, p=0.778) and adjusted OR was 1.18 (95% CI: 0.36-3.89, p=0.786). High-risk HPV (hrHPV) infections of tobacco and non-tobacco users' groups were found in 2/3 and 27/49 (55.1%), respectively. CONCLUSIONS: This study showed an insignificant statistical association between tobacco use and HPV infection in normal uterine cervix. However, the proportion of hrHPV infection was higher in tobacco users than non-users. From the SDGs perspective, cervical cancer is closely related to tobacco use and poverty. Further study is needed to support this result and evaluate other co-factor role-related cervical cancer history to achieve SDGs in 2030.
ABSTRACT
BACKGROUND: Artemisinin-based combination therapy is very effective in clearing asexual stages of malaria and reduces gametocytemia, but may not affect mature gametocytes. Primaquine is the only commercially available drug that eliminates mature gametocytes. METHODS: We conducted a 2-arm, open-label, randomized, controlled trial to evaluate the efficacy of single-dose primaquine (0.75 mg/kg) following treatment with dihydroartemisinin-piperaquine (DHP) on Plasmodium falciparum gametocytemia, in Indonesia. Patients aged ≥5 years with uncomplicated falciparum malaria, normal glucose-6-phosphate dehydrogenase enzyme levels, and hemoglobin levels ≥8 g/dL were assigned by computerized-generating sequence to a standard 3-day course of DHP alone (n = 178) or DHP combined with a single dose of primaquine on day 3 (n = 171). Patients were seen on days 1, 2, 3, and 7 and then weekly for 42 days to assess the presence of gametocytes and asexual parasites by microscopy. Survival analysis was stratified by the presence of gametocytes on day 3. RESULTS: DHP prevented development of gametocytes in 277 patients without gametocytes on day 3. In the gametocytemic patients (n = 72), primaquine was associated with faster gametocyte clearance (hazard ratio = 2.42 [95% confidence interval, 1.39-4.19], P = .002) and reduced gametocyte densities (P = .018). The day 42 cure rate of asexual stages in the DHP + primaquine and DHP-only arms were: polymerase chain reaction (PCR) unadjusted, 98.7% vs 99.4%, respectively; PCR adjusted, 100% for both. Primaquine was well tolerated. CONCLUSIONS: Addition of single-dose 0.75 mg/kg primaquine shortens the infectivity period of DHP-treated patients and should be considered in low-transmission regions that aim to control and ultimately eliminate falciparum malaria.
