However, few or no data are available regarding serum proteins RIs, especially in resource-limited countries such as Ethiopia.Objective: To establish RIs for serum protein electrophoresis of apparently healthy adults in Addis Ababa, Ethiopia.Methods: A cross-sectional study was conducted on a total of 297 apparently healthy adults from April to October 2019 in four selected sub-cities (Akaki, Kirkos, Arada, and Yeka) of Addis Ababa, Ethiopia. Laboratory analysis of collected samples was performed using the Capillarys 2 Flex Piercing analyzer, while statistical analysis was conducted using SPSS version 23 and Med-Calc software.

Socio-demographic characteristics and duration of exposure data were collected using a structured questionnaire and an observation checklist. Sysmex XP-300 was used for hematological analysis and stained peripheral blood smear was examined for any abnormality. Data were entered and analyzed using SPSS version 23.Results: Of exposed individuals, 28/43 (65.1%) and 49/77 (63.6%) of controls were males. The average exposure time was 5.19± 4.38 years, with an average working hour of 11.74± 1.89 hours/day. The mean RBC count (1012/L), HCT (%), HGB (g/dl) and platelets count (109/L) of the exposed group were significantly lower (4.88± 0.573, 43.29± 3.71, 15.04± 1.33 and 248.95± 58.19) compared with controls (5.35± 0.533, 44.95± 3.10, 15.59± 1.26 and 292.45± 62.17) at p< 0.05, respectively. The MCH (pg) (30.48± 2.06 vs 29.52± 1.66) and MCHC (g/dl) (34.83± 0.988 vs 34.32± 0.927) were significantly higher in the exposed group compared with controls (p< 0.05). HCT, RBC

Hypothyroidism is one of the severe adverse drug reactions (ADRs) in MDR-TB patients on treatment. Representative data on hypothyroidism and its associated factors among MDR-TB patients are lacking.Objective: To determine thyroid profiles and associated risk factors among multidrug-resistant TB patients during therapy with anti-MDR-TB regimen in Saint Peter Specialized Hospital Addis Ababa, Ethiopia from January to November 2020.Methods: A cross-sectional study was conducted in MDR-TB patients in Addis Ababa, Ethiopia. A total of 162 patients, who were older than 18 years, had bacteriologically confirmed MDR-TB and on treatment for more than one month were enrolled consecutively from the TB registration book. However, critically sick patients and those who were receiving additional drugs known to cause severe ADRs were excluded. Simple descriptive statistics were used to present the socio-demographic and clinical characteristics of the patients. A logistic regression model was used to assess the association between independent and dependent variables. A p-value < 0.05 was considered as statistically significant in all analyses.Results: Mean age of the study participant was 35.9 ± 13.6 years. The prevalence of hypothyroidism was 32 (19.8%).

Here, we aim to assess the effect of S. mansoni infection on immune modulation of human monocytes and their potential protection against autoimmune disease development both in vivo and in vitro.Materials and Methods: Monocytes were isolated from helminth-infected Ethiopians (MHIE), and from Dutch healthy volunteers (MHV). The MHV were stimulated in vitro with S. mansoni soluble egg antigens (SEA) or soluble worm antigens (SWA). In addition, phenotypical changes were studied directly, as well as after culturing for 6 days in the presence of human serum to obtain macrophages. Q-PCR, flow cytometry, multiplex bead immunoassay, and live-cell imaging were employed during analysis.Results: MHIE showed elevated transcripts of SOCS-1 and TNF-α compared to MHV. Similarly, MHV that were stimulated with SEA demonstrated enhanced levels of SOCS-1, IL-10, and IL-12 mRNA, compared to control MHV. Remarkably, the SEA-treated monocytes showed a much higher motility than control monocytes, a hallmark of a patrolling phenotype. Furthermore, in vitro cultured macrophages that were stimulated by SEA exhibi

Vitamin A concentration was measured using high-performance liquid chromatography (HPLC), whereas iron and vitamin B12 concentrations were measured using Cobas® 6000 analyzer.Result: The serum concentration levels of iron, vitamin A and vitamin B12 had a significant difference between active TB and latent (LTBI) or healthy controls. Six months after treatment, the serum concentration levels of vitamin A, vitamin B12 and iron in tuberculosis became indistinguishable from the levels of LTBIs and healthy control individuals. The concentration levels of iron and vitamin B12 in HIV+TB+patients at the end of TB treatment were normalized to the levels observed in healthy controls (TST–) regardless of HAART treatment. However, the concentration level of vitamin A in HIV+TB+patients HAART untrea
