Anemia affects approximately 30% of children all over the world. Acute respiratory tract infections (ARTI), urinary tract infections (UTI) and gastroenteritis (GE) are common infectious entities in children. Here, we assessed the association between anemia and development of recurrent ARTI, UTI, and GE in children. This was a case-control study in hospitalized 2–5 years old children in Professorial Pediatric Unit at Teaching Hospital Anuradhapura, Sri Lanka. An 18-month follow up was done to assess the risk factors for the development of recurrent ARTI, GE, UTI, and control presented without infections. Further, 6-month follow up done after 3-month iron supplementation to assess the occurrence of recurrences. Blood Hb concentration was measured using Drabking’s reagent. Logistic regression was used to find the risk factors for the development of recurrences. In ARTI, 121/165 (73.3%), GE, 88/124 (71%), UTI 46/96 (47.9%) and control 40/100 (40%) were having anemia. Initial ARTI group, recurrent ARTI was 24 (14.5%, p = 0.03); initial GE group: recurrent GE was 14 (11.3%, p = 0.03), recurrent ARTI was 11 (8.9%, p = 0.04); initial UTI group, development of; recurrent UTI was 8 (8.3%, p = 0.04); control, recurrent ARTI was 11 (11%, p = 0.03). Following 3-month iron supplementation reduction of recurrences was significant: initial ARTI recurrent ARTI in 90%, recurrent GE in 77.7%; initial GE recurrent GE in 83.3%, recurrent ARTI in 80%; initial UTI recurrent ARTI in 71.4% and control recurrent ARTI in 88.8%. Iron deficiency is a major type of anemia and anemic children are more prone to develop recurrent ARTI and GE. Once iron deficiency being corrected the rate of recurrent ARTI and GE was reduced. This would be a boost for policy developers to implement strategies at the community level to prevent iron deficiency in children to reduce ARTI and GE recurrences.
IntroductionThe use of anti-retroviral therapy (ART) has dramatically reduced HIV-1 associated morbidity and mortality. However, HIV-1 infected individuals have increased rates of morbidity and mortality compared to the non-HIV-1 infected population and this appears to be related to end-organ diseases collectively referred to as Serious Non-AIDS Events (SNAEs). Circulating miRNAs are reported as promising biomarkers for a number of human disease conditions including those that constitute SNAEs. Our study sought to investigate the potential of selected miRNAs in predicting mortality in HIV-1 infected ART treated individuals.Materials and MethodsA set of miRNAs was chosen based on published associations with human disease conditions that constitute SNAEs. This case: control study compared 126 cases (individuals who died whilst on therapy), and 247 matched controls (individuals who remained alive). Cases and controls were ART treated participants of two pivotal HIV-1 trials. The relative abundance of each miRNA in serum was measured, by RTqPCR. Associations with mortality (all-cause, cardiovascular and malignancy) were assessed by logistic regression analysis. Correlations between miRNAs and CD4+ T cell count, hs-CRP, IL-6 and D-dimer were also assessed.ResultsNone of the selected miRNAs was associated with all-cause, cardiovascular or malignancy mortality. The levels of three miRNAs (miRs -21, -122 and -200a) correlated with IL-6 while miR-21 also correlated with D-dimer. Additionally, the abundance of miRs -31, -150 and -223, correlated with baseline CD4+ T cell count while the same three miRNAs plus miR-145 correlated with nadir CD4+ T cell count.DiscussionNo associations with mortality were found with any circulating miRNA studied. These results cast doubt onto the effectiveness of circulating miRNA as early predictors of mortality or the major underlying diseases that contribute to mortality in participants treated for HIV-1 infection.
Objectives We have assessed the risk factors for the occurrence of hospital-acquired (HA) and community-acquired (CA) viral acute respiratory tract infections (ARTIs) in children. Children (1–60 months) who were having ARTI on admission (CA) and develops ARTI following 48 h after admission or 3 days of discharge (HA) were included. Indirect immunofluorescence assay (IFA) was performed and multivariable analyses were done to determine the risk factors for the development of viral CA and HA-ARTI. Results Total of 818 with ARTIs, 226 (27.6%) RSV cases were detected. Out of 226, 86 (38.0%) HA-RSV cases were detected. CA-viral-ARTI was significantly high (p < 0.05). Compared to CA-RSV-ARTI immunodeficiency, seizures, trisomy-21 and congenital heart disease (CHD) were having 2.3, 3.2, 1.8- and 2.2-times risk for acquiring HA-RSV respectively. The number of deaths was significantly high following HA-RSV. The associated burden was significant following HA-RSV and it was 429.77 disability-adjusted life years. Children who are having immunodeficiency, CHD, seizure episodes and trisomy 21 would lead to the acquisition of nosocomial RSV infections in great. Adherence to meticulous infection control practices will be helpful to minimize the HA-viral ARTIs in great.
