Antiretroviral Therapy and Detection of High-grade Cervical Intraepithelial Neoplasia (CIN2+) at Post-CIN Management Follow-up Among Women Living With Human Immunodeficiency Virus: A Systematic Review and Meta-Analysis.

BACKGROUND: We evaluated the association of antiretroviral therapy (ART), CD4+ count and human immunodeficiency virus (HIV) plasma viral load (PVL) on high-grade cervical intraepithelial neoplasia (CIN2+) detection at follow-up after CIN management among women living with HIV (WLHIV). METHODS: Medline, Embase, Global Health, and PubMed were searched from 1 January 1996 to 15 January 2020. Eligible studies investigated the association of ART, CD4+ count, or HIV PVL on histology-confirmed CIN2+ detection at follow-up. Summary estimates were obtained using random-effects meta-analyses; heterogeneity was examined using I2 statistic. PROSPERO registration: CRD42018115631. RESULTS: Eight studies representing 9 populations were identified, including 1452 WLHIV followed between 6 and 33 months post-CIN management. Pooled data from 8 populations (n = 1408) suggested weak evidence of a decreased risk of CIN2+ detection at follow-up among ART users compared to ART-naive women (crude odds ratio [cOR] = 0.70, 95% confidence interval [CI]: .36-1.36; I2 = 64.5%, P = .006; adjusted risk ratio [aRR] from 3 studies = 0.66, 95% CI: .20-2.24; I2 = 78.7%, P = .009). A significant association was observed in high-income countries (cOR = 0.24, 95% CI: .13-.45; I2 = 0.0%, P = .77) but not in low and middle-income countries (cOR = 1.13, 95% CI: .67-1.92; I2 = 18.8%, P = .30).In 3 populations, ART users with HIV PVL <50 copies/ml were less likely to have CIN2+ detection at follow-up (vs ≥50 copies/mL: cOR = 0.55, 95% CI: .32-.94; I2 = 0.0%, P = .23).There was weak evidence of decreased CIN2+ detection at follow-up among WLHIV with higher contemporary CD4+ cell counts (≥200 cells/µL vs <200 cells/µL [cOR = 0.36, 95% CI: .04-3.13; I2 = 81.3%, P = .021]) and significant evidence among women with a higher nadir CD4+ count (≥350 cells/µl vs <200 cells/µl [adjusted hazard ratio [aHR] = 0.35, 95% CI: .15-.84; I2 = 0%, P = .64]). CONCLUSION: ART may reduce the risk of CIN2+ detection at follow-up; this effect is most likely enhanced by a combination of adequate HIV control and excisional CIN treatment. Our findings support recommendations of early ART and the integration of CIN2+ screening and management into HIV care.

Global epidemiology of acute generalised peritonitis: a protocol for a systematic review and meta-analysis.

INTRODUCTION: Globally, acute generalised peritonitis (AGP) is a common medical and surgical emergency which is a major contributor to non-trauma deaths despite improvements in diagnosis and surgical and intensive care management. In order to determine the global burden of AGP, geared at tailoring key interventions to curb its morbidity and mortality, we proposed this first ever systematic review and meta-analysis to estimate the contemporary prevalence, and to determine the most frequent AGP and the case fatality rate of AGP, at the global scene. METHODS AND ANALYSIS: We intend to search AfricanJournalsOnline, Americana em Ciências da Saúde, Citation index, EMBASE, Global Index Medicus, Literatura Latino Africa Index Medicus, Medline and Scientific Electronic Library Online databases from 1 January 2009 to 31 July 2019 to identify studies that reported the prevalence, types of AGP, and case fatality rate of AGP in the global population without any language restrictions. Study selection, data extraction and risk of bias assessment will be conducted independently at each level by a pair of independent investigators. Random-effects meta-analysis will be used to pool studies judged to be clinically homogeneous. The presence of heterogeneity will be evaluated using the χ² test on Cochrane's Q statistic and quantified with the I² statistics. Publication bias will be evaluated statistically and visually using the Egger's test and funnel plots, respectively. Findings will be reported and compared by countries, WHO regions and globally. ETHICS AND DISSEMINATION: Since this study will be based on published data, it does will not require an ethical approval. The findings will be published in a scientific peer-reviewed journal. They will also be presented at scientific conferences and to relevant public health actors. PROSPERO REGISTRATION NUMBER: CRD42019143331.
