Screening approaches for cervical cancer in Mozambique in HIV positive and negative women.

OBJECTIVE: Cervical cancer (CC) is a global health issue, in Mozambique, 5300 new cases and 3800 deaths are reported each year. The WHO recommends the introduction of HPV molecular testing for CC screening, but Mozambique uses an approach based on visual inspection with acetic acid (VIA). This study aims to evaluate the feasibility of high-risk HPV (hrHPV) testing compared to actual approaches in Mozambique. METHODS: An observational study was carried out in the DREAM center in Zimpeto, Mozambique. Women aged 30-55 were included. HPV testing was performed with the Cobas HPV test. They were then screened with the current national recommendations based on VIA. Cryotherapy was performed on-site or referred for colposcopy if necessary. RESULTS: In the period, 1207 women were enrolled, 47.8% HIV+; 124 (10.3%) VIA+, and HPV DNA test was positive in 325 (26.9%) women. HPV positivity rates were higher in HIV-infected women. In the sample, 52.8% of the 124 VIA+ women were HPV uninfected and underwent unnecessary cryotherapy or colposcopy. Meanwhile, 24.7% of the 1083 VIA- women were actually HPV infected. In comparison, a screen, triage and treat approach based on hrHPV testing would only test and treat the 325 HPV-infected women. CONCLUSION: The study found high rates of hrHPV infection, particularly in HIV-positive women, with many concurrent or multiple infections. The current screening method misses important hrHPV infections and results in many unnecessary treatments. These results support the use of HPV molecular testing as the initial screening test for CC.

Early detection of poor glycemic control in patients with diabetes mellitus in sub-Saharan Africa: a cohort study in Mozambique.

Introduction: WHO estimates 422 million cases of diabetes mellitus worldwide. Mozambique has the second-highest mortality related to DM in the African region.Objectives of the present study are to provide data about a DM care service in Mozambique and to evaluate early outcomes of treatment. Methods: The new patients diagnosed with DM in a two-years period in a health centre in Maputo (Mozambique) were included in a retrospective cohort study. Fasting blood glucose (FBG), waist circumference (WC) and BMI were collected at baseline and after three months. Results: 188 patients were enrolled. Median BMI, WC and FBG at baseline were respectively 28 kg/m2(Inter Quartile Range [IQR]23.4-31.8), 98cm (IQR 87-105) and 209mg/dL (IQR 143-295). A non-pharmacological intervention was prescribed for six patients, while 182 patients received metformin 500 mg b.i.d. FBG was significantly reduced at control (226[±103.7]mg/dL vs 186[±93.2]mg/dL, p<0.000); however, glycemic control was reached in 74 patients (39.4%); not controlled patients changed regimen. Elderly patients had a higher glycemic control (adjusted Odds Ratio 2.50, 95% CI 1.11-5.06, p=0.002). Conclusion: Strategies for early detection of scarce glycemic control are feasible in Mozambique and could lead to prompt regimen switch; an invasive therapeutic approach could be preferable in selected cases to achieve control.

Hypercholesterolemia and related risk factors in a cohort of patients with diabetes and hypertension in Maputo, Mozambique.

INTRODUCTION: some studies reported that 25.5% of African population presents hypercholesterolemia; however, epidemiology of hypercholesterolemia in Africa is poorly described. Mozambique is experiencing a constant growth of non-communicable diseases, but scarce data are available about hypercholesterolemia. Our study aims at describing the prevalence of hypercholesterolemia in patients with diabetes and hypertension in Mozambique and investigate possible risk factors. METHODS: we conducted a cross-sectional study involving all the patients diagnosed with hypertension and/or diabetes from June 2018 to November 2020 in the Zimpeto DREAM Centre (Maputo, Mozambique). For each patient, anthropometric, clinical and laboratory data were collected. Hypercholesterolemia was defined as total blood cholesterol >200 mg/dL. Univariable and multivariable analysis were perfumed. RESULTS: a total of 885 patients were included, 76.2% (n=674) female. Hypertension alone was diagnosed in 670 (75.7%) patients, diabetes in 109 (12.3%) patients and 106 (11.9%) both diseases. Hypercholesterolemia was present in 410 (46.3%) patients and it was more prevalent in patients diagnosed with both diabetes and hypertension (52.8%), as compared to the patients diagnosed with hypertension (46.9%) or diabetes alone (36.7%). In the multivariable analysis, the only factors independently associated with hypercholesterolemia were female sex (aOR 1.77, 95% CI 1.26-2.48, p=0.001) and a body mass index >25kg/m2 (aOR 1.50, 95% CI 1.11-2.04, p=0.008). CONCLUSION: our results highlight the need for a specific focus on female and obese/overweight patients, especially if diagnosed with both hypertension and diabetes, to promptly detect metabolic disorders and establish temporary preventive measures for cardiovascular events.
