Aim: This study was conducted to compare different cytological findings with cervical HPV infection among women presenting for cervical cancer screening in Gombe north-eastern Nigeria. Study Design: It is a hospital based cross-sectional study. Place and Duration of Study: Departments of Obstetrics/Gynaecology and Histopathology Federal Teaching Hospital Gombe (FTHG) Nigeria, between August 2013 and May 2014. Methodology: Two hundred and nine (209) women were subjected to liquid-based cervical cytology and HPV DNA testing. Results: Of the 209 participants, cytological findings were normal in 126 (61.6%) women while 80 (39.0%) had abnormal features. Three (1.4%) respondents had unsatisfactory smears. The observed abnormal cytological features include HPV changes 30 (14.4%), HPV changes with inflammation 2 (1.0%), inflammatory changes alone 36 (17.3%), Low Squamous Intraepithelial Lesion; LSIL 3 (1.4%), High Squamous Intraepithelial Lesion; HSIL 5 (2.4%) and malignant changes 3 (1.4%). Positive HPV DNA testing was detected among 100 (48.1%) of the participants. Almost half 60 (47.6%) of the women with normal cytology were positive for HPV. Among women with cytologically detected HPV changes, only 16 (50%) were also HPV DNA positive. The sensitivity and specificity of cervical cytology in detecting HPV infection was 16.2% and 85.0% respectively. Conclusion: This study reports a very low sensitivity but relatively high specificity of cytology in detecting cervical HPV infection. It further justifies the need for introduction of HPV DNA testing to improve efficiency and maximise the sensitivity of cytology based cervical cancer screening for women above 30 years.
Epidemiological patterns of cervical human papillomavirus infection among women presenting for cervical cancer screening in North-Eastern Nigeria
(BioMed Central Ltd, 2015) Manga, M. M.; Fowotade, A.; Abdullahi, Y. M.; El-nafaty, A. U.; Adamu, D. B.; Pindiga, H. U.; Bakare, R. A.; Osoba, A. O.
Background: Sub-Saharan countries including Nigeria have the highest burden of Human Papillomavirus (HPV) infection in the world. Most studies on HPV surveillance in Nigeria were done in the southern part of the country. Geographical and socio-cultural diversity of Nigeria makes these data unlikely to be universally representative for the entire country. Northern Nigeria especially the North-East carries a higher prevalence of cervical cancer and many of its risk factors. The region may be harbouring a higher prevalence of HPV infection with a possibility of different genotypic distribution. This study was carried out to determine the burden and confirm the predominant HPV genotypes among women presenting for cervical cancer screening at the Federal Teaching Hospital Gombe (FTHG), North-eastern, Nigeria. Methods: The study was an observational hospital based cross sectional study among women who presented for cervical cancer screening in FTHG. A total of 209 consenting women were tested for cervical HPV infection using PCR. DNA sequencing was carried out on positive samples to determine the prevalent HPV genotypes. Results: The prevalence of cervical HPV infection among the participants with mean age of 39.6 ± 10.4 years was 48.1 %. The five most predominant genotypes were 18, 16, 33, 31 and 35, with prevalence of 44.7 %, 13.2 %, 7.9 %, 5.3 % and 5.3 % respectively. Other genotypes observed were 38, 45, 56, 58, 82 and KC5. Multiple HPV infections were detected among 7.9 % of participants. Risk factors such as level of education (X2 = 15.897; p = 0.007), age at sexual debut (X2 = 6.916; p = 0.009), parity (X2 = 23.767; p = 0.000), number of life time sexual partners (X2 = 7.805; p = 0.005), age at first pregnancy (X2 = 10.554; p = 0.005) and history of other malignancies (X2 = 7.325; p = 0.007) were found to have a statistically significant association with HPV infection. Conclusion: This study identified a high burden of HPV infection in Northern Nigeria while also confirming HPV 18 and 16 as the most predominant genotypes. It further justifies the potential benefit of the currently available HPV vaccines in the area. A larger and community based study is however recommended for better representation of the area.
Morphological Pattern of Endometrial Biopsies In South Western Nigeria.
(Association of Resident Doctors, University College Hospital, 2016) Abdullahi, Y. M.; Ajani, M. A.; Iyapo, O.; Aramide, K. O.; Okolo, C. A.; Akang, E. E.
Background: Endometrium remains the most sensitive indicator of ovarian function and endometrial biopsy is one of the diagnostic procedures in endometrial pathology. The current study was carried out to examine the morphological pattern of endometrial biopsies in Ibadan, South-western Nigeria and compare the results with similar studies. Method: A retrospective study was undertaken to review all cases of endometrial biopsies received in the Department of Pathology, University College Hospital, Ibadan between January 1999 and December 2008. The patients’ data were retrieved from the surgical pathology daybooks and Histology Request forms. The neoplastic lesions were classified according to 2003 World Health Organization classification for endometrial neoplasms. Results: A total of 2,444 cases of endometrial biopsies were received during the 10-year study period. The functional endometrial changes were the most common histopathological diagnostic category, accounting for 53.8% (1035) of cases. Other pathological diagnoses included endometritis (7.8%), simple endometrial hyperplasia (5.8%), partial hydatidiform mole (2.3%), complete hydatidiform mole (2.1%) and malignant neoplastic lesions (3.9%). Infertility was the most common (57%) indication for endometrial biopsies followed by uterine bleeding (33%) while the least common clinical indication were the menstrual disorders (10%). Conclusion: The functional endometrial changes account for the highest morphological patterns while malignant lesions account for the least pattern of the endometrial biopsies evaluated for etiological basis of infertility, uterine bleeding and menstrual disorders in Ibadan. Infertility was the commonest indication for endometrial biopsies while the least common clinical indication was menstrual disorders.
