Latent Tuberculosis Infection Status of Pregnant Women in Uganda Determined Using QuantiFERON TB Gold-Plus.

BACKGROUND: The risk of progression of latent tuberculosis infection (LTBI) to active disease increases with pregnancy. This study determined the prevalence and risk factors associated with LTBI among pregnant women in Uganda. METHODS: We enrolled 261 pregnant women, irrespective of gestational age. Participants who had known or suspected active tuberculosis (TB) on the basis of clinical evaluation or who had recently received treatment for TB were excluded. LTBI was defined as an interferon-γ concentration ≥0.35 IU/mL (calculated as either TB1 [eliciting CD4+ T-cell responses] or TB2 [eliciting CD8+ T-cell responses] antigen minus nil) using QuantiFERON TB Gold-Plus (QFT-plus) assay. RESULTS: LTBI prevalence was 37.9% (n = 99) (95% confidence interval [CI], 32.3-44.0). However, 24 (9.2%) subjects had indeterminate QFT-plus results. Among participants with LTBI, TB1 and TB2 alone were positive in 11 (11.1%) and 18 (18.2%) participants, respectively. In multivariable analysis, human immunodeficiency virus (HIV) infection (adjusted odds ratio [aOR], 4.4 [95% confidence interval {CI}, 1.1-18.0]; P = .04) and age 30-39 years (aOR, 4.0 [95% CI, 1.2-12.7]; P = .02) were independently associated with LTBI. Meanwhile, smoking status, alcohol use, nature of residence, crowding index, and TB contact were not associated with LTBI. CONCLUSIONS: Our findings are in keeping with the evidence that HIV infection and advancing age are important risk factors for LTBI in pregnancy. In our setting, we recommend routine screening for LTBI and TB preventive therapy among eligible pregnant women.

Optimizing diabetes mellitus care to improve COVID-19 outcomes in resource-limited settings in Africa.

Diabetes mellitus (DM) is an important risk factor for both severe disease and death due to coronavirus-2019 (COVID-19). About 19 million of the 463 million persons living with DM (PLWD) globally are found in sub-Saharan Africa (SSA). The dual burden of DM and poverty in SSA, coupled with the rising number of cases of COVID-19 in this region, predisposes PLWD to inadequate care and poor glycemic controls due to the disruption to the economy and the healthcare system. The risk of acquisition of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) among PLWD is the same as those in the general population. Therefore, the standard preventive measures outlined by the World Health Organization must be strictly adhered to. In addition, maintaining adequate glycemic control is associated with better outcomes in DM patients with COVID-19. In SSA, adequate supply of DM medication while patients stay at home is crucial to minimize routine hospital visits since DM clinics are usually overcrowded and have longer waiting times, which may maximize risk of SARS-CoV-2 transmission to PLWD across the region. Psychosocial support to improve adherence to anti-hyperglycemic medications may improve COVID-19 outcomes. Trained healthcare professionals should diagnose and evaluate severity comprehensively as well as evaluate the need for in-patient care for PLWD with COVID-19 irrespective of disease severity. Due to the increased risk of severe disease, a multi-disciplinary approach to the management of COVID-19 in PLWD should preferably be in a setting where close monitoring is available, typically a health facility, even for mild disease that may require home management according to local guidelines. In conclusion, DM complicates COVID-19 outcomes and the on-going COVID-19 pandemic adversely affects DM care at individual and global public health levels. PLWD should be prioritized as COVID-19 vaccines are being rolled out.

Anemia in Ugandan pregnant women: a cross-sectional, systematic review and meta-analysis study.

BACKGROUND: Anemia in pregnancy represents a global public health concern due to wide ranging maternal and neonatal adverse outcomes in all peripartum periods. We estimated the prevalence and factors associated with anemia in pregnancy at a national obstetrics and gynecology referral hospital in Uganda and in addition performed a systematic review and meta-analysis of the overall burden of anemia in pregnancy in Uganda. METHODS: We conducted a cross-sectional study among 263 pregnant women attending the antenatal care clinic of Kawempe National Referral Hospital, Kampala, Uganda, in September 2020. Anemia in pregnancy was defined as a hemoglobin level of < 11.0 g/dl and microcytosis as a mean corpuscular volume (MCV) of < 76 fL. We also performed a systematic review (PROSPERO Registration ID: CRD42020213001) and meta-analysis of studies indexed on MEDLINE, Embase, African Journal Online, ClinicalTrials.gov , ICTRP, and the Cochrane Library of systematic review between 1 January 2000 and 31 September 2020 reporting on the prevalence of anemia in pregnancy in Uganda. RESULTS: The prevalence of anemia was 14.1% (n= 37) (95%CI 10.4-18.8), of whom 21 (56.8%) had microcytic anemia. All cases of anemia occurred in the second or third trimester of pregnancy and none were severe. However, women with anemia had significantly lower MCV (75.1 vs. 80.2 fL, p<0.0001) and anthropometric measurements, such as weight (63.3 vs. 68.9kg; p=0.008), body mass index (25.2 vs. 27.3, p=0.013), hip (98.5 vs. 103.8 cm, p=0.002), and waist (91.1 vs. 95.1 cm, p=0.027) circumferences and mean systolic blood pressure (BP) (118 vs 125 mmHg, p=0.014). Additionally, most had BP within the normal range (59.5% vs. 34.1%, p=0.023). The comparison meta-analysis of pooled data from 17 published studies of anemia in pregnancy in Uganda, which had a total of 14,410 pregnant mothers, revealed a prevalence of 30% (95% CI 23-37). CONCLUSIONS: Despite our study having a lower prevalence compared to other studies in Uganda, these findings further confirm that anemia in pregnancy is still of public health significance and is likely to have nutritional causes, requiring targeted interventions. A larger study would be necessary to demonstrate potential use of basic clinical parameters such as weight or blood pressure as screening predictors for anemia in pregnancy.
