Kogbe OI, Measles: Symptoms, Diagnosis, and Treatments - Healthline Ogaro (Ogaro 1993) reported on this outcome and showed increased chances of recovery in the vitamin Asupplemented group, which were statistically significant. Kawasaki (Kawasaki 1999) alone reported the duration of cough, in days. Effect of Vitamin A supplementation on childhood morbidity and mortality, Overcrowding and intensive exposure as determinants of measles mortality. There was also a lack of reporting on the immunization status of children in the general population and in the study population, which was reported in only two studies (Dollimore 1997; Hussey 1990). Permeisih D, government site. There was an 83% reduction in risk of mortality (RR 0.21; 95% CI 0.07 to 0.66) in the vitamin Asupplemented group in children under two years of age, in studies that used two doses of 200,000 IU of vitamin A (Barclay 1987; Coutsoudis 1991; Hussey 1990). We had some concerns about whether some trial authors collected data but later chose not to report these findings. Three trials recruited highrisk participants defined as those living in areas with casefatality > 10% or aged two years or less. Kiepiela P, Please do not hesitate to contact us. Minder C. Bias in metaanalysis detected by a simple, graphical test. HY and Chao Min Wan (CW) were responsible for data extraction and rewriting the updated review. Recent studies show that vitamin A levels decrease during measles and that vitamin A therapy can improve measles outcome in children in the developing world. Managing measles | Political Economy | thenews.com.pk Underwood BA, However, data were collected and no side effects were reported in any of the studies. RT @NHSEnglandLDN: Has your child missed an MMR (measles, mumps and rubella) vaccination? There is limited information to permit a generalization in relation to highincome countries. Idjradinata YR, Vaccination schedule for Vitamin A - World Health Organization As stated a priori (D'Souza 1999), outcomes were mortality; pneumoniaspecific mortality; development of pneumonia, diarrhea, croup and otitis media; and duration of hospitalization, fever, pneumonia and diarrhea. About half of these deaths occur in Africa (MMWR 1998). Learn about this vaccine-preventable disease that used to be common in childhood and is well known for a characteristic red, splotchy rash and high fever. In Coutsoudis' study (Coutsoudis 1991) the supplemented group had significantly higher concentrations than the placebo group, which indicates that the liver stores were not depleted but that there was temporary impairment of mobilization and increased utilization of vitamin A. Rosales (Rosales 1996) reported on this outcome and there was an increased risk that the vitamin A group still had cough at the end of two weeks but this was not statistically significant. If, in the original reports, participants were not analyzed in the group to which they were randomized, and there was sufficient information in the trial report or in information obtained from the trial authors, we planned to restore them to the correct group and analyze accordingly (i.e. Vitamin A reduces the risk of death from measles by 87% for children younger than 2 years. The definition of pneumonia was a clinical case definition or by radiological confirmation. Vitamin A can, therefore, be used for the treatment of measles and may be beneficial either by reducing the effects of measles infection (therapeutic effect) or preventing the subsequent development of secondary infection (protective effect), or both (Coutsoudis 1991). An official website of the United States government. Measles is a major cause of death in children in low-income countries and is particularly dangerous in children with vitamin A deficiency. Although the data do not allow us to examine the individual effects of dose and formulation, these are issues that need to be considered.

To determine whether vitamin A is beneficial in preventing mortality, pneumonia and other secondary infections in children with measles. Hussaini G, At each round, information was obtained on illnesses within the past week, the child's weight, and left midupper arm circumference and, from the second dosing round, on hospitalization or measles since the last visit. No studies required reanalysis with the original allocated treatment groups being restored to their correct groups. Overall, the seroconversion rates did not differ between vitamin A (89.5%) and placebo (87.6%) groups. It is possible that, in high doses, oilbased and waterbased vitamin A have similar effects in children under the age of two years. Kawasaki showed a one and a half day statistically significant reduction in the duration of fever (MD 1.5; 95% CI 2.04 to 0.96) while Coutsoudis showed a little over half a day (MD 0.60; 95% CI 0.81 to 0.39). The Emerging Science of Integrative Medicine | Psychology Today Coutsoudis A, Rosales (Rosales 1996) did not find any benefit in the vitamin Atreated group. The only study carried out in a highincome country (Japan) used onefourth of the recommended dose (100,000 IU), showed a reduced morbidity and did not report any toxicity. Those aged six months or over at a visit were given a dose of vitamin A (100,000 IU of retinol equivalent for children aged 6 to 11 months or 200,000 IU for older children) or placebo. Hussey (Hussey 1990) reported the number of participants who had pneumonia for more than 10 days. If your child has missed a dose, we will contact you. The World Health Organization (WHO) recommends administration of an oral dose of vitamin A (200,000 international units (IU), or 100,000 IU in infants) each day for two days to children with measles when they live in areas where vitamin A deficiency may be present. 'retinol'/de AND [embase]/lim 22,205 28 Feb 2011 Most of the morbidity outcomes are either based on single or two studies, except for croup. These two studies individually did not show any statistical reduction in the incidence of pneumonia. #11 AND #14 112 28 Feb 2011 Higher Vitamin D Dose in Childhood Linked to Lower Mental - Flipboard In the current version of the review, however, there were not enough trials reporting on the same outcomes to present a meaningful analysis. Sowell AL, West CE, The oilbased preparation is more stable, readily available and costs less. 64 If 85% efficacy is assumed for single dose measles vaccine, these serology results would . The factors included in the subgroup analyses of dose, formulation, setting and age were highly correlated and three studies (Barclay 1987; Coutsoudis 1991; Hussey 1990) were strongly represented in these analyses. The children in the Rosales (Rosales 1996) and Ogaro studies may not have benefited from receiving vitamin A oilbased preparations in a single dose (200,000 IU) as this might not have been sufficient to reverse the hyporetinemia occurring during measles; the dose may have been stored, mostly in the liver. 2 exp MEASLES VIRUS/ Mild vitamin A deficiency and risk of respiratory tract diseases and diarrhea in preschool and school children in northeastern Thailand. Fawzi WW, Data were to be reported qualitatively when a quantitative analysis proved unfeasible or inappropriate. We believe it is imperative that the Cochrane Collaboration examine the Vitamin A for treating measles in children review by Huiming Y, Chaomin W, and Meng M.The review incorrectly includes a study by Dollimore et al. Although this study used very small doses of vitamin A (3000 IU for seven days) the supplemented group had statistically significant reductions in risks of mortality, even in the absence of antibiotics and immunization. Wedel M, Acne, psoriasis, and other skin disorders Also, none of the studies reported malaria as a coinfection with measles. The degree of retinol depression is associated with the severity of illness (Butler 1993). Sutkover Morris S.

Available from www.cochranehandbook.org. This was seen across all studies but more so in the studies that used the twodose regimen (Barclay 1987; Coutsoudis 1991; Hussey 1990). An additional (third) age-specific dose of vitamin A should be given 2-4 weeks later to children with clinical signs and symptoms of vitamin A deficiency. Ogaro (Ogaro 1993) reported the number of participants that recovered from pneumonia in less than eight days. Photo Credits: Tran Thi Hoa Why is vitamin A important for treating measles? This could have been an important difference, possibly resulting in an inability to demonstrate a protective effect of vitamin A in the supplemented group. official website and that any information you provide is encrypted The site is secure. The World Health Organization (WHO) recommends administration of an oral dose of 200,000 IU (or 100,000 IU in infants) of vitamin A per day for two days to children with measles in areas where vitamin A deficiency may be present. So it is difficult to determine whether the children received Vitamin A before or after onset of measles. The Rosales and Dollimore studies differed from the other studies in patient setting, follow up, disease severity, patient age, vitamin A preparation used and analytical approach. Vitamin A for treating measles in children - PubMed Two doses of vitamin A are not considered to be too expensive, and are not likely to produce adverse effects. Coutsoudis gave two additional doses on days eight and 42. 3. We support the WHO recommendation that two doses of vitamin A (200,000 IU) be given to all cases of measles, especially to children under the age of two with severe measles, in addition to the standard treatment. Coutsoudis (Coutsoudis 1991) found that the vitamin A group had a 1.5 times better chance of complete clinical recovery than the placebo group, which was statistically significant. et al. Djunaedi E, Peterson DE, We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 1), which contains the Cochrane Acute Respiratory Infections Group's Specialized Register, MEDLINE (1966 to February week 3, 2011) and EMBASE (1980 to February 2011). 454 likes, 43 comments - Ayurved Mera Mahan (@ayurved_mera_mahan) on Instagram: "Participate No.29 LEMON Botanical name :-Citrus limon Family :- Rutaceae Ayurvedic . The study by Markowitz et al (Markowitz 1989) highlighted the fact that children aged less than two years of age with low vitamin A levels had a higher risk of dying than those with higher levels; the number of children in the age group older than two years were too few to detect any statistically significant difference. They used two doses, hospitalized participants, children under the age of two and were carried out in areas where the casefatality rate is high. Vitamin A status appeared to be satisfactory and at least 30% of Ogaro's participants had vitamin A levels greater than 20 ug/dl. Muherdiyantiningsih BS, The World Health Organization (WHO) recommends a daily oral dose of vitamin A for two days to children with measles living in areas where vitamin A deficiency may be present. Muhilal, In Barclay's study (Barclay 1987) the staff and participants were blinded but not the treating physician who also assessed the outcomes. Summary: A recent study suggests higher doses of Vitamin D3 supplementation during early childhood may reduce the risk of internalizing psychiatric symptoms in later years. These studies were done under controlled conditions and their follow up was relatively brief. Measles is a viral disease that infects and damages these tissues (Morley 1969a). Campaign vs. measles, rubella reaches 78% coverage Nonetheless, we have reported all results, even those measured and reported by a single study. Although all the studies reported the baseline nutritional status of the vitamin Asupplemented and placebo groups only, Barclay specified the nutritional status of the children who died; vitamin A recipients suffered lower mortality at every nutritional level. We have rounded these off to 98 and 107 per 1000 respectively. Vitamin A supplementation reduces measles morbidity in young African children: a randomized, placebo controlled, double blind trial. They were of different durations, in slightly different age groups, using different doses of vitamin A in different formulations (oil or waterbased), in different settings (hospital or community) and in different geographical areas with varying measles casefatality rates. It raises the issue of whether the decrease in mortality was a result of the higher dose, or whether the vitamin A supplementation in higher casefatality areas had a greater effect, as there was a greater potential for mortality decline in those populations. Cystic fibrosis. We have analyzed the risk of bias in all individual trials in detail in 'Risk of bias' tables. The protective effect of vitamin A supplementation was seen only in hospitalized children. We will assess funnel plot asymmetry visually and use formal tests for funnel plot asymmetry. Vitamin A for treating measles in children - PubMed Risk of bias graph: review authors' judgements about each risk of bias item presented as percentages across all included studies. Broughton M, Eight trials met the inclusion criteria (2574 participants). Hussey 1990 confirmed that treatment with vitamin A reduced measles morbidity and mortality. Barclay 1987 drew attention to the importance of vitamin A therapy in reducing measles mortality and led to the 1987 joint recommendation between the World Health Organization (WHO) and the United Nations International Children's Fund (UNICEF) for the administration of a single oral dose of vitamin A (200,000 international units (IUs), or 100,000 IUs in infants) at the time of initial measles diagnosis in nonxerophthalmic children who lived in areas where measles casefatality rates were greater than 1% (WHO 1988). Havens PL, Rubeola / Measles | CDC Yellow Book 2024 When the studies that used the twodose regimen were stratified by formulation (whether water or oilbased) an 81% reduction in the risk of mortality (RR 0.23; 95% CI 0.06 to 0.89) was seen in studies that used waterbased preparations. The data is updated regularly with the most recent official country reporting collected through the WHO/UNICEF joint reporting process.

Careers, Unable to load your collection due to an error. The study by Rosales (Rosales 1996) used a single dose of vitamin A and did not show any benefit on pneumonia continuing for two weeks. One study (Barclay 1987) used two doses of oilbased vitamin A and the effect on overall mortality was not significant on its own, except for children under the age of two years. These three studies were also done in areas where the hospital casefatality rate was more than 10%. Cutts F, We used odds ratios (ORs) and their 95% confidence intervals (CIs) to calculate the risk ratio (RR) and 95% CI. Measles - Symptoms and causes - Mayo Clinic The demographic, nutritional, immunological and clinical status at baseline all affect the comparability between the vitamin Atreated and control groups (Coutsoudis 1991). At this cost "to achieve significant reductions in hospitalizations and costs in terms of mortality and longterm morbidity, vitamin A therapy for the management of measles is highly costeffective" (Cervinskas 1996). Vijayaraghavan K, National Library of Medicine The children in the Rosales (Rosales 1996) and Ogaro (Ogaro 1993) studies may not have benefited from receiving vitamin A oilbased preparations in a single dose (200,000 IU) as this might not have been sufficient to reverse the hyporetinemia occurring during measles; the dose may have been stored, mostly in the liver. We also wish to thank the ARI Group Review Group Coordinator Liz Dooley and Sarah Thorning, the Trials Search Coordinator who provided invaluable assistance for this review. Although in South Africa the measles casefatality rate was greater than 10% in hospitals, Coutsoudis had low casefatality rates in both the vitamin A and control groups. Herrera MG, We measured precision using 95% confidence intervals (CI).

To study the benefits in children older than two years of age, more children in this age group need to be enrolled. Federal government websites often end in .gov or .mil. Measles is caused by a virus and possible complications include pneumonia. Duggan MB, Onyango FE, Sowell AL, Two review authors (HY, CW) independently selected trials for inclusion. There was sufficient evidence at that time to demonstrate that vitamin A supplementation reduced childhood mortality and morbidity (Sommer 1996) but there were only two studies demonstrating the effect of vitamin A in the treatment of children with measles. Khatry SK, For the first version of the review published in The Cochrane Library 2001, Issue 1, the authors used the search strategy developed by the Cochrane Acute Respiratory Infections Group (Cochrane 1999). The quality of most of the trials included in this review is high. Different doses of vitamin A were used in this review. Three significant studies (Barclay 1987; Coutsoudis 1991; Hussey 1990) present most frequently in all the five subgroup analyses: dose, formulation, hospitalization, age and casefatality in the study area. Two doses of vitamin A reduced the incidence of croup (RR 0.53; 95% CI 0.29 to 0.89) but not pneumonia morbidity (RR 0.92; 95% CI 0.69 to 1.22), nor diarrhea morbidity (RR 0.80; 95% CI 0.27 to 2.34). There is limited information to permit a generalization in relation to highincome countries. Waterbased vitamin A preparations lead to greater absorption, which results in higher serum retinol levels. Secondly, not all settings, even in Africa, have high measles casefatality rates and the usefulness of vitamin A supplementation where mortality and severe complications are much less frequent, has had limited study" (Ogaro 1993). Katz J, Finally, we registered a permanent search with Current Contents to notify the authors by email of any new trials published in journals indexed by Current Contents. In Hussey's study 64% of children had diarrhea and pneumonia on admission; while in Barclay's study pneumonia was the most frequent complication, affecting 85 children: 43% in the vitamin A group and 51% in the control group. For continuous outcomes we will use the test proposed by Egger 1997, and for dichotomous outcomes we will use the test proposed by Harbord 2006. One trial (Chowdhury 2002) was excluded because it studied the effect of vitamin A supplementation on childhood morbidity but not for treating measles in children. We described for each included study the method used to conceal the allocation sequence in sufficient detail and determined whether intervention allocation could have been foreseen in advance of, or during recruitment, or changed after assignment. The subgroup analyses are very restricted as the same studies are represented in all of them. Some studies have found vitamin A to have little effect on morbidity, while causing a significant reduction in mortality (Rahmathullah 1990; Rahmathullah 1991; Sommer 1986). We assessed the trials and did not find any other problems that could put them at a high risk of bias. Orinda VA, For this 2011 update we searched the Cochrane Central Register of Controlled Trials (CENTRAL) 2011, Issue 1, part of The Cochrane Library,www.thecochranelibrary.com (accessed 1 March 2011), which includes the Cochrane Acute Respiratory Infections Group's Specialized Register, MEDLINE (January 2009 to February week 3, 2011) and EMBASE (March 2009 to March 2011). Vitamin A deficiency is when your body lacks the amount of vitamin A it needs to function properly. Risk of bias summary: review authors' judgements about each risk of bias item for each included study. If a test for heterogeneity was negative, then we calculated a weighted estimate of the typical treatment effect across trials. Cleveland Clinic is a non-profit academic medical center. The Beaton 1993 review concluded that " in the specific case of measles, there is evidence that improvement of vitamin A status, even after the onset of infection, can improve both the course of the episode and the case fatality rate". Therefore, randomized controlled trials need to be conducted that would compare single doses (200,000 IU) of oil or waterbased vitamin A with two doses, and have sufficiently large sample sizes that the results could be stratified across subgroups for age, geographical areas with low and high casefatality rates, and hospitalized and nonhospitalized children. It is assumed that all have been followed up until they were discharged from hospital. Salisbury RT, LeClerq SC, Dollimore used at least two doses of vitamin A and showed there was no significant difference in the risk of mortality in the community between vitamin Asupplemented and placebo groups. Vitamin A in a single dose for treating measles in children was not associated with a reduced risk of mortality. The study carried out by Barclay showed a 48% reduction and Hussey showed a statistically significant 79% reduction in the risk of mortality. Because low serum levels of vitamin A are associated with severe disease due to measles, vitamin A treatment is recommended for all children with measles. Effectiveness of measles vaccination and vitamin A treatment We noted no selective reporting of particular outcomes within trials in this review. There is the possibility that more severe clinical cases of measles are more likely to benefit from vitamin A treatment. Impact of vitamin A supplementation on childhood mortality. Vitamin A deficiency can cause vision loss and blindness. The evidence partly supports the WHO recommendation of two 200,000 IU doses. #5. When the seven highquality studies reporting on mortality (Barclay 1987; Coutsoudis 1991; Dollimore 1997; Hussey 1990; Kawasaki 1999; Ogaro 1993; Rosales 1996) were pooled together, the summary estimate of the effect of vitamin A on the risk of mortality associated with measles was not significant (RR 0.83; 95% CI 0.51 to 1.34). New citation required but conclusions have not changed. et al. It may also be worth mentioning that the objectives of those reviews were different from the objective of this review. Problems with the pancreas that occur with cystic fibrosis increase the risk of vitamin A deficiency . #12 OR #13 841,197 28 Feb 2011 The evidence for oilbased vitamin A having a protective effect on mortality was demonstrated when an old study by Ellison with a lower quality score was included as part of the sensitivity analysis. Two studies (Coutsoudis 1991; Kawasaki 1999) reported on the duration of fever, in days. His study used a single dose of vitamin A and did not show any benefit. Tarwotjo I, The cost of a dose of vitamin A is around USD 0.02 (WHO 1998). We used the following terms in MEDLINE and CENTRAL and adapted them for EMBASE.

Six of the studies (Barclay 1987; Coutsoudis 1991; Dollimore 1997; Hussey 1990; Ogaro 1993; Rosales 1996) were conducted in Africa, one in Japan (Kawasaki 1999) and one in England (Ellison 1932). This reflects the patientcare conditions under which the majority of measles cases are diagnosed and treated in lowincome countries (Dollimore 1997; Rosales 1996). 10 Vitamin A.tw,nm. There was a significant decrease in the incidence of croup with vitamin A supplementation while there was no significant reduction in the incidence of pneumonia, although a reduction was observed in the duration of diarrhea, pneumonia, fever, hospital stay and cough. Coovadia HM. Milton RC, In developing countries where vitamin A deficiency is common, children with measles are more likely to have severe symptoms and may die from the disease. If asymmetry is detected in any of these tests or is suggested by a visual assessment, we will perform exploratory analyses to investigate it. Until 1993, there were no reports of acute vitamin A toxicity in children with measles who took the WHO recommended dose as reported by the Committee on Infectious Diseases of the American Academy of Pediatrics (Pediatrics 1993). Egger M, 'measles'/de OR 'measles virus'/de AND 12,117 28 Feb 2011, New search for studies and content updated (no change to conclusions).

VITAMIN A - Uses, Side Effects, and More - WebMD Hussey (Hussey 1990) demonstrated that the duration of hospital stay for children given vitamin A was decreased by an average of 4.7 days; by half a day in another study (Kawasaki 1999). It also occurs in people with immune disorders, most commonly because of decreased intake or absorption of vitamin A. Ogaro FO, However, these symptoms are minor and transitory, with no known longterm effects and requiring no special treatment (WHO 1998). . Measles kills up to 10% of people it infects and, while cases are more common in low- and middle-income countries, measles outbreaks happen in all countries. Transmission Measles is transmitted from person to person via respiratory droplets and by the airborne route as aerosolized droplet nuclei. sharing sensitive information, make sure youre on a federal Therefore, the presence of correlated characteristics between these factors cannot be ruled out as firstly the data cannot be stratified because the raw data were not available and, secondly, there were too few studies to stratify across the five subgroups.
