Background: There are no robust national prevalence of Human Papillomavirus (HPV) genotypes in Nigerian women despite the high burden of cervical cancer morbidity and mortality. The objective of study: This study aims to determine the pooled prevalence and risk factors of genital HPV infection in Nigeria through a systemic review protocol. Methods: Databases including PubMed, Scopus, Google Scholar and AJOL were searched between 10 April to 28 July 2020. HPV studies on Nigerian females and published from April 1999 to March 2019 were included. GRADE was used to assess the quality of evidence. Results: The pooled prevalence of cervical HPV was 20.65% (95%CI: 19.7-21.7). Genotypes 31 (70.8%), 35 (69.9%) and 16 (52.9%) were the most predominant HPV in circulation. Of the six geopolitical zones in Nigeria, northeast had the highest pooled prevalence of HPV infection (48.1%), while the least was in the north-west (6.8%). After multivariate logistic regression, duration (years) of sexual exposure (OR ¼ 3.24, 95%CI: 1.78-9.23]), history of other malignancies (OR ¼ 1.93, 95%CI: 1.03-2.97]), history of sexually transmitted infection (OR ¼ 2.45, 95% CI: 1.31-3.55]), coital frequency per week (OR ¼ 5.11, 95%CI: 3.86-14.29), the status of circumcision of the sexual partner (OR ¼ 2.71, 95%CI: 1.62-9.05), and marital status (OR ¼ 1.72, 95%CI: 1.16-4.72), were significant risk factors of HPV infection (p < 0.05). Irregular menstruation, postcoital bleeding and abdominal vaginal discharge were significantly associated with HPV infection (p < 0.05). Conclusion: HPV prevalence is high in Nigeria and was significantly associated with several associated risk factors. Rapid screening for high-risk HPV genotypes is recommended and multivalent HPV vaccines should be considered for women.

Background: Although an increasing access to ART in sub-Saharan Africa has made it possible for HIV/AIDS patients to live longer, clinicians managing such patients are faced with the challenge of drug-related metabolic complications. Methods: A cross -sectional study was carried out at the University of Calabar Teaching Hospital, Nigeria, on three groups of participants; namely HIV patients on ART, ART-naïve patients and HIV negative subjects (n =75). Demographic and anthropometric data were collected using a well-structured questionnaire while biochemical parameters were measured using colorimetric methods. Results: The highest prevalence of MS was associated with the HIV/AIDS patients on ART (i.e. 32.0 %, and 50.3% for NCEP-ATP III and IDF criteria respectively). Patients on ART had significant increases (p< 0.05) in waist to hip ratio, FPG, serum TG and LDL-c; and a significantly higher (p< 0.05) prevalence of hypertension, diabetes, low HDL-c and hypertriglyceridaemia compared to the ART-naïve patients. Low serum HDL-c was the most prevalent form of dyslipidaemia in allthree groups and the most prevalent component of MS in HIV patients. Conclusion: ART increases the risk of MS and CVD. HIV/AIDS patients on ART should be advised on lifestyle modifications and undertake regular assessment of their cardiovascular risk factors.
