The transcription factor NF-κB promotes immunity by controlling the expression of genes involved in inflammation. Cytokines and pathogen-associated molecular patterns stimulate cell surface receptors, including toll-like receptors, to initiate a signalling cascade resulting in the activation of NF-κB. NF-κB drives the expression of target genes that mediate cell proliferation and release antimicrobial molecules and cytokines to activate an immune response. Filariasis is one of the most complex infections of humans. The actual causes of the heterogeneity in infection are not well understood. However, they have been attributed to differences in inflammatory processes that are immune-mediated, secondary bacterial infections, and host immune-genetics. Elevated production of angiogenic molecules (VEGFs, CEACAM and MMPs) in filarial pathology has been shown to be dependent on phosphorylation and intracellular activation of NF-κB. This review examines the role of NF-κB in filarial pathology and its potential therapeutic options for individuals with the disease.

Background and Aims: Children with sickle cell disease (SCD) have an increased risk of multiple hemotransfusions and this can predispose them to elevated iron stores.The objectives of the study were to determine the extent of elevated iron stores and the associated risk factors in a population of steady-state SCD children in Ghana.Methods: This cross-sectional study was conducted at the pediatric sickle cell clinic at the Komfo Anokye Teaching Hospital. Complete blood count and serum ferritin assay were performed for (n = 178) steady-state SCD children. Descriptive and multivariate logistic regression analysis were performed. Elevated iron stores were defined as serum ferritin levels >300 ng/ml. Statistical significance was considered at p < 0.05. Results:The mean (standard deviation) age of the participants was 9.61 (±4.34) years, and 51% of them were males. About 17% of SCD children had elevated iron stores and receiving at least three hemotransfusions during the last 12 months was strongly associated with elevated iron stores (p < 0.001). History of chronic hemotransfusion increased the odds of having elevated iron store (adjusted odds ratio [aOR] = 11.41; 95% confidence interval [CI] = 3.11-30.85; p < 0.001) but SCD patients on hydroxyurea treatment had reduced-odds of having elevated iron stores (aOR = 0.18; 95% CI = 0.06-0.602; p = 0.006). Moreover, red blood cell

Filarial infections caused by nematodes are one of the major neglected tropical diseases with public health concern. Although there is significant decrease in microfilariae (mf) prevalence following mass drug administration (IVM/DEC/ALB administration), this is transient, in that there is reported microfilaria repopulation 6-12 months after treatment. Wolbachia bacteria have been recommended as a novel target presenting antibiotic-based treatment for filarial disease. Potency of antibiotics against filarial diseases is undoubtful, however, the duration for treatment remains a hurdle yet to be overcome in filarial disease treatment.

The insurgence of COVID‐19 has received all attention at the detriment of research on most diseases. Procedures and protocols devised to curb the pandemic continues to affect lives and work. As most countries prepare to tune back to normalcy, working conditions undoubtedly will not be the same as the World Health Organization still urges nations to scale up procedures and strategies against the pandemic. As research groups and projects across the globe and especially in Ghana begins work, these protocols must be fashioned into their study protocol before approval will be granted by ethical institutions. This has led to increase in research cost, with additional responsibilities aside their normal research activities. This perspective clearly points out the impact of the pandemic on research, especially fieldwork.
