Profile of Endoscopic Lesions and Prevalence of <i>H. pylori</i>Infection at the Digestive Endoscopy Unit of Panzi General Reference Hospital in Bukavu

Introduction: Thanks to the opening of the digestive endoscopy unit in the Reference General Hospital of Panzi in Bukavu in the Democratic Republic of the Congo, which inspired our work on the profile of endoscopic lesions observed in a series of 1000 patients correlated with clinical and demographic criteria with the contribution of pathology examinations of the 292 biopsies performed. The aim of our work is to evaluate the prevalence of significant endoscopic lesions as well as that of H. pylori infection. Material and Methods: This is a retrospective, descriptive and analytical study, ranging from the 16th of December 2014 to the 16th of June 2016. It covered 1000 patients who benefited from a high digestive endoscopy and 292 of them had a biopsy with pathological examination. The data obtained were recorded and analyzed using the Epi-info software and chi-square test. Results: fifty-five percent of these patients were women. 66% of the patients were under 50 years of age. Their major symptom was epigastric pain (89.2%), the most observed endoscopic lesion was erythematous gastritis (82%) therefore we have noticed 21.5% of significant lesions. Gastric cancer was present in 3.9% of cases and gastric ulcer in 4.2% of cases. The gastric tumor was correlated with age and sex (P-value at 0.000 and 0.013). The gastroduodenal ulcer was linked to age, NSAID and tobacco use (P-value at 0.0007, 0.001, 0.007). Esophageal mycosis was correlated with HIV status (P-value at 0.000). Helicobacter pylori gastritis was the most frequent (61.30%) and Helicobacter pylori were present in 63% of gastric biopsies. Conclusion: Upper digestive endoscopy is a major tool for the diagnosis of upper gastrointestinal disorders and should always be followed by a biopsy if there is a suspicious lesion for pathologic confirmation and adequate management.

The Place of Human Papillomavirus Test in the Screening of Intraepithelial Lesions of Cervix in South-Kivu Province, DR Congo

Introduction: Human papillomavirus (HPV) infection remains the most common cause of cervical intraepithelial neoplasia. The objective of this study is to evaluate the sensitivity and predictive value of the HPV test associated with the cervico-uterine smear in the screening of cervical intraepithelial neoplasia in our environment. Methodology: This is a descriptive cross-sectional study of 625 women who consulted in the department of gynecology for cervical cancer screening, of whom 300 received an HPV test;during the period from January the 1st to December 31st, 2018 at Panzi general reference hospital (South-Kivu, DRC). Data analysis was done using Epi Info version 7 software. Results: For all respondents (n = 625), the cervico-uterine smear was normal in 82.88%, inflammatory in 2.4% of cases and with cellular atypia in 14.72%. The HPV test was positive in 87 respondents against 213 negatives cases, i.e. a prevalence of HPV of 29% [95% CI: 23.9% - 34.5%]. Among women with precancerous lesions, 27.6% had HPV infection;among those with normal smears, 29.3% of them had HPV infection;however, this difference was not statistically significant. Patients with dysplastic lesions, 31.3% had genotypes with very high carcinogenic potential;and for those with a normal Pap smear, 45.1% had genotypes with very high carcinogenic potential;however, this difference was also not statistically significant. Conclusion: The human papillomavirus test remains a very important indication cation in the detection of cervical intraepithelial neoplasia, its sensitivity remaining clearly superior to that of cytology, especially for high grade lesions.
