Estimating the Risk of Women Anemia Associated with Ozone Exposure Across 123 Low- and Middle-Income Countries: A Multicenter Epidemiological Study

Anemia in women of reproductive age (WRA) presents a pressing global public health issue, particularly in low- and middle-income countries (LMICs). Yet, the potential impact of ozone (O3) exposure on anemia remains uncertain. The study included 1,467,887 eligible women from 83 surveys of 45 LMICs between 2004 to 2020. Monthly O3 exposure was estimated using machine learning, with the year preceding the survey as the primary exposure window. Fixed-effects models evaluated the association between O3 and anemia. An exposure-response function (ERF) was constructed using a varying-coefficient regression model, and then extrapolated to estimate the anemia burden in relation to O3 in 123 LMICs. In the fully adjusted regression model, each 10 ppb increase in annual O3 concentration was associated with an 8% elevation in anemia risk. The nonlinear ERF indicated a threshold effect of O3 on anemia at approximately 47.2 ppb. In 2020, more than 7.6 million anemic WRA (1.58%) in 123 LMICs were associated with O3 exposure. The potentially attributable burden has generally decreased from 2004 to 2020, notably in South Asia. Our findings highlight the importance of air pollution mitigation in LMICs to address anemia disparities among women.

Influence of Rectal Ozone Application on the Intensity of Free Radical Destruction of Lipids and Intestinal Proteins in the Dynamics of Experimental Colitis

We studied clinical status, content of products of LPO, and oxidative modification of proteins (OMP) in the lesion focus of the intestine in experimental colitis under conditions of rectal administration of ozone. Experimental colitis was simulated by two-stage administration of oxazolone; rectal insufflation of ozone in the ozone-oxygen mixture was performed daily. The disease activity index (DAI), the content of calprotectin in the feces, and LPO and OMP products in the intestinal homogenate were assessed. On days 2, 4, and 6 of the pathological process, DAI, concentration of calprotectin in feces, content of primary, secondary, and end-products of LPO in the heptane and isopropanol phases, and content of primary and secondary OMP products progressively increases. Under conditions of ozone application, DAI, concentration of calprotectin in feces, the levels of heptane- and isopropanol-soluble primary, secondary, and end-products of LPO, and the level of primary and secondary products of OMP decreased on days 4 and 6; the level of isopropanol-soluble primary, secondary, end-products of LPO increased on day 2 of experimental colitis. The severity of clinical manifestations weakens as the content of LPO and OMP products in the colon decreases on days 4 and 6 of observation.

Immune changes at the injured sites in oxazolone-induced ulcerous colitis: Influence of ozone therapy

Impaired immunoregulation and development of autoimmune response to antigens of own intestinal microbiota and inflammation-altered antigens of colonic cells represent the key links in pathogenesis of inflammatory bowel diseases. Multimodal biological effects of ozone presunme the usage of local and systemic ozone therapy in complex treatment of many inflammatory diseases of the gastrointestinal tract. The aim of our work was to study effects of intraperitoneal and rectal ozone therapy upon immune parameters of the lesion focus in oxazolone-induced ulcerative colitis in the course of time. The study was carried out on 64 adult male inbred Wistar rats weighing 240±20 g. Experimental ulcerative colitis was produced by oxazolone treatment (4-ethoxymethylene-2-phenyl-2-oxazolin-5-one) (SigmaAldrich, USA). The ozone-oxygen mixture was injected intraperitoneally or rectally at a concentration of 1.0-1.2 mg/l, once a day, in a volume of 10 ml, at the 6-day course. The results of experiments were recorded on the days +2, +4 and +6. The concentrations of IL-17 and IL-23 was determined in a homogenate of intestinal tissues (Bender Medsystems, Austria) using a Personal LAB analyzer; expression of CD4 and FoxP3 on intestinal lymphocytes was determined by immunohistochemistry technique (ElisaKit, China). The observed tissue damage of large intestine showed an increase from day 2 to day 6 of oxazolone-induced ulcerative colitis. The total number of lymphocytes significantly increased upon development of experimental colitis, with parallel decrease in the number of CD4+ lymphocytes and FoxP3-positive T lymphocytes. IL-17 and IL-23 concentrations in the tissues increased with the severity of inflammatory changes in the lesion focus. Intraperitoneal ozone administration was associated with significant reduction of lymphocyte contents in the damaged tissues on the 6th day, whereas the numbers of CD4+ and FoxP3 positive T lymphocytes normalized by the 6th day. The levels of IL-17 and IL-23 increased from day 2 to day 6, with a lower IL-23 values on day 6 as compared with non-treated animals. Rectal administration of ACS led to the normalization of FoxP3 cells on the 6th day to the values of intact animals. The levels of proinflammatory cytokines (IL-17 and IL-23) significantly decreased on the 6th day as compared to the group of animals without treatment, which could be due to anti-inflammatory properties of ozone.
