Xerophthalmia among hospitalized Iraqi children.

To determine the impact of sanctions on the nutritional status of Iraqi children aged < 6 years, a random sample of 700 patients (age range: 0-6 years) from the Saddam Paediatric Hospital, Diyala Province, Iraq were examined ophthalmologically for evidence of xerophthalmia. Data on the history of infection, feeding and night blindness were also collected. The prevalence of xerophthalmia was 29%, mostly among children aged 1-3 years. Xerophthalmia was significantly inversely associated with breastfeeding and highly associated with common childhood infections such as measles, diarrhoea and respiratory tract infection. Xerophthalmia is a common problem among sick Iraqi children. Efforts to identify, evaluate and monitor vitamin A deficiency and to advocate and plan its eradication should be implemented.

Xerophthalmia and malnutrition among pre-school children in Agaro town south-west Ethiopia.

A community-based cross-sectional study was undertaken in Agaro town to determine the magnitude of xerophthalmia and malnutrition in January 1993. 434 children (aged six months to six years), were selected randomly and by using the proportionate probability sampling technique from the eight 'kebeles' of the town. Data were collected by interviewing mothers/ care-takers of index children and by ocular and anthropometric examinations. From the total subjects studied, the proportion of males (54.6%) was higher than females (45.3%). Few mothers/ care-takers (24.5%) were found to be illiterate. According to the Waterloo classification, 18.6% were either wasted, stunted or both. The overall prevalence of xerophthalmia was 6.2%. Being malnourished and earning less than 700 birr / year were significantly associated with xerophthalmia (chi 2 = 6.23; P < 0.05). Finally, children with clinical signs of xerophthalmia and other eye diseases were treated accordingly and advice was given to mothers/care-takers of malnourished children.

Detection of early xerophthalmia by impression cytology.

Vitamin A deficiency causes blindness, increased systemic morbidity, and increased mortality among preschool children in many developing nations. Presently, there is no simple, reliable test to detect early, physiologically significant vitamin A deficiency. We used conjunctival impression cytology results to evaluate children with early xerophthalmia before treatment and again three to eight weeks later. Subsequently, we modified our technique. We then compared children with early xerophthalmia to normal children. Conjunctival impressions from children with xerophthalmia all showed complete loss of goblet cells and the appearance of enlarged, partially keratinized epithelial cells. Conjunctival impressions from treated and normal children showed normal goblet cells and sheets of small epithelial cells. These results suggest impression cytology may represent the first simple, objective, diagnostic test for the detection of early vitamin A deficiency.

Secondary ocular bacterial infection in hypovitaminosis a xerophthalmia.

Extraocular bacterial culture was performed in 100 patients with hypovitaminosis A xerophthalmia. There was corneal ulceration in 29 cases and corneal perforation in 22 cases. Eighty-six percent of the patients harbored frankly pathogenic bacteria (46 patients) and potentially pathogenic bacteria (40 patients). All but two patients with either cornal ulceration or perforation harbored potentially pathogenic or frankly pathogenic bacteria. Pseudomonas aeruginosa, Diplococcus pneumoniae, and Moraxella species were isolated in 37% (19 patients) of cases with corneal ulceration and perforation. I cultured P. aeruginosa from 36% (eight patients) of cases with corneal perforation. The many ocular secondary bacterial infections in the early stages of xerophthalmia seem to suggest that bacterial action plays a major role in causing the corneal ulceration and perforation in hypovitaminosis A xerophthalmia.

Association of xerophthalmia, flecked retina, and pseudotumor cerebri caused by hypovitaminosis A.

PURPOSE: To report an unusual case of hypovitaminosis A with bilateral papilledema and flecked retina that regressed after restoration of vitamin A deficiency. METHOD: Case report. A 27-year-old woman had undergone a biliopancreatic bypass for obesity in 1990. In 1995, she presented with bilateral xerophthalmia, bilateral papilledema, and bilateral flecked retina. RESULTS: Laboratory tests demonstrated low serum levels of vitamin A (0.8 micromol/l) and vitamin E (8.54 micromol/l). Xerophthalmia, papilledema, and flecked retina disappeared after restoration of normal vitamin A blood levels. CONCLUSION: Hypovitaminosis A after biliopancreatic bypass for obesity may be associated with xerophthalmia, pseudotumor cerebri, and flecked retina.

A nutrition rehabilitation centre for children with xerophthalmia.

A nutrition rehabilitation centre for treatment of children with xerophthalmia was established in Madurai, India. Treatment was based on provision of locally available food, rich in protein and beta-carotene and cheap enough for the families concerned to buy at home. This diet alone, with general medical treatment for other diseases, was sufficient to reverse conjunctival xerophthalmia and corneal xerosis. Children with more severe xerophthalmia received additional vitamin A. The records of 296 children followed up for between two months and three years were analysed. The results of treatment at the centre seemed as good as those produced by more expensive, and usually unobtainable, hospital treatment. Participation of the mother in buying, cooking, and sharing the food given to her child was of some educational value.

Child feeding and care behaviors are associated with xerophthalmia in rural Nepalese households.

The study examined caregiver-child interactions, intrahousehold food allocation and general child care behaviors and their effect on children's xerophthalmia status in the rural Terai region of Nepal. Seventy-eight households with a child having a history of xerophthalmia (cases) were matched with 78 households with a child of the same age having no history of xerophthalmia (controls). Seven day-long continuous monitoring observations were performed in each household (over 15 months) by trained Nepali observers, focusing on feeding and care of a focus child and his/her younger sibling. Nineteen different behavioral variables were operationalized, including serving method, second helpings, serving refusals, encouragement to eat, request intensity, meal serving order, food channeling, food sharing, positive social behaviors, negative social behaviors, and positive health behaviors. Automatic serving and request intensity were strongly negatively correlated, especially among younger siblings. Children who serve themselves receive less encouragement to eat. Those children who are refused in their requests for food tend to ask for food more frequently, for a longer time, and be less likely to self-serve. Children who eat from a shared plate are less likely to interact with a food server and more likely to self-serve. Negative social behavior towards children is associated with the child having to request food more frequently and a greater likelihood of being refused food. Children who receive positive health care from their caregivers are also more frequently asked if they would like food by the server and are encouraged to eat. Several caregiver child feeding behaviors were related to a child's risk of having past vitamin A deficiency. Controls were much more likely to be served food automatically. Cases were more likely to serve themselves food and have multiple servings of food. Cases were nearly two times more likely than controls to be treated with neglect or harshly, and much less likely than controls to have their health needs receive attention. Examining intrahousehold behavior is critical for understanding the causes of vitamin A deficiency in rural Nepalese children, and has great potential for identifying and improving interventions to improve children's diets and care.

[Cataract Eye Camp in India, Xerophthalmia Project. Experiences last January within the scope of the Combat Blindness Foundation at the Sitapur Ophthalmology Hospital in India].

In India are approximately 4 million blind people by advanced or mature cataract. For only 10 US$ one patient can be operated in eye camps in the villages by an intracapsular cataract cryoextraction an + 12.00 dptr. aphakia glasses. Also estimated four million people are blind by xerophthalmia. The project is to examine all the babies and little children in the villages and to give them for 2 years each month vitamin-A-medication. On the other side the parents of children suffering from xerophthalmia are instructed to plant vegetables rich in vitamin A. The goal of both projects is to make a cataract and xerophthalmia free zone in Uttar Pradesh, which should spread over the entire country. Both projects are sponsored by Combat Blindness Foundation, P.O. Box 5, 332 Madison Wisconsin 53705 USA, Professor Suresh Chandra, chairman.

Xerophthalmia and blindness in Northeast Brazil.

Dietary and biochemical data have indicated that hypovitaminosis A is a public health problem in Northeast Brazil. However, there are few reports regarding clinical signs of hypovitaminosis A. Therefore, an epidemiological study was designed to study this problem. The study as done was primarily a review of hospital records of xerophthalmia in each state with attention paid to other nutrition factors. It was found that xerophthalmia is a problem in Northeast Brazil and a cause of blindness in certain areas. However, the number varied greatly from some states to others. Around 1,000 preschool-age children were recorded as blind from vitamin A deficiency in a 1-year period. It was also noted that the peak incidence of xerophthalmia and blindness was around 1 year of age. The government of Brazil is taking urgent measures to combat this deficiency with such measures as the supplementation of sugar with vitamin A and the distribution of massive doses of vitamin A.

Xerophthalmia in the state of Paraiba, northeast of Brazil: clinical findings.

An epidemiological survey of the prevalence of xerophthalmia was conducted in the state of Paraiba through 10,922 clinical examinations of 0 to 12 yr old children from six localities representative of the three different ecological regions of Paraiba. The regional distribution of clinical signs of vitamin A deficiency was markedly different, and in the semiarid region (Sertão) the prevalence reached levels suggesting that it was a public health problem in that area. Seasonal variations were observed and were specially significant in the "Sertão," with xerophthalmia signs appearing more frequently during the interharvest period. This seems to be the first report with documented active cases of xerophthalmia in this region of Brazil.

Hyporetinolemia and acute phase proteins in children with and without xerophthalmia.

BACKGROUND: The relations among hyporetinolemia, acute phase proteins, and vitamin A status in children are unclear. OBJECTIVE: The objective was to examine the relations between acute phase proteins and plasma retinol concentrations in children with and without clinical vitamin A deficiency (Bitot spots and night blindness). DESIGN: The study was a nonconcurrent analysis of acute phase protein concentrations and other data from a previous clinical trial. Preschool children, 3-6 y of age, with (n = 118) and without (n = 118) xerophthalmia were assigned to receive oral vitamin A (60 mg retinol equivalent) or placebo and were seen at 5 wk. All children received oral vitamin A (60 mg retinol equivalent) at 5 wk. RESULTS: At baseline, alpha(1)-acid glycoprotein (AGP) was elevated in 42.9% and 23.5% (P < 0.003) and C-reactive protein (CRP) was elevated in 17.7% and 13.7% (NS) of children with and without xerophthalmia, respectively. Hyporetinolemia (retinol < 0.7 micromol/L) occurred in 61.0% and 47.4% (P < 0.04) of children with and without xerophthalmia, respectively. A history of fever, a history of cough, and nasal discharge noted on examination were each associated with elevated acute phase proteins. Vitamin A supplementation increased plasma retinol at 5 wk but had no significant effect on concentrations of acute phase proteins. CONCLUSIONS: Elevated acute phase protein concentrations and infectious disease morbidity are closely associated during vitamin A deficiency.

Risk factors associated with xerophthalmia in northern Sudan.

The prevalence of eye signs and symptoms of vitamin A deficiency was determined among 29,615 Sudanese children between 6 and 72 mo of age, in five rural areas of Khartoum and Gezira provinces. Of all children, 2.9% were vitamin A deficient, and of these > 90% had Bitot's spots. Bivariate associations were found between xerophthalmia and the rural councils where the children lived, household wealth, consumption of vitamin A-containing foods, child sex, child age and weight-for-height Z-scores. Multivariate analysis showed that the following factors made significant independent contributions to the risk of xerophthalmia: living in remote and arid regions, male gender, age, poverty of the household, and prevalence of diarrhea. On the other hand, less xerophthalmia was observed among children who during the 24 h preceding the survey had consumed dairy products or non-leafy vegetables containing vitamin A. Intervention programs aimed at increasing household income and promoting consumption of foods containing vitamin A should contribute to the reduction of vitamin A deficiency among Sudanese children.

Xerophthalmia among Nepalese children.

A nationwide sample survey was conducted between July 1980 and June 1981 to determine the prevalence of xerophthalmia among Nepalese children. Population proportionate random samples were drawn from the 12 geopolitical subdivisions of the country by employing multistage sampling technique. The survey population was defined as the child population of rural Nepal between the ages of 0 and 14 years. The per cent prevalence of xerophthalmia in Nepal was 1.65 for Bitot's spots, 0.02 for corneal ulcer, and 0.03 for corneal scar. While cases of Bitot's spots were more prevalent in the plains of Nepal, followed by the mountains and the hills, the reverse was true for corneal lesions. Vitamin A deficiency was found to be responsible for one-third of acquired bilateral blindness in preschool children. All corneal cases in the study were accompanied by diarrhea and malnutrition, indicating xerophthalmia to be symptomatic of the whole spectrum of malnutrition.

A prevalence study of vitamin A deficiency and xerophthalmia in northeastern Thailand.

An epidemiologic survey of the prevalence of xerophthalmia and vitamin A deficiency was conducted in May and June 1985 in a multistage random sample of 1,772 children 1-8 years of age from 16 rural villages and the capital city of the Sakon Nakhon province in northeastern Thailand. Data of clinical eye examinations were available for 92% (n = 903) of the eligible children aged 1-5 years (n = 982); history of night blindness was obtained from a reliable source from 93% (n = 1,644) of the whole sample; and biochemical data were available for 60% (1,060) of the children examined. The distribution of clinical signs of xerophthalmia and serum retinol levels differed between the rural and urban areas. In the urban area, no signs of xerophthalmia or deficient serum retinol levels were found in the preschool children examined. The prevalence of night blindness in the rural area was 1.3% in children aged 1-5 years (95% confidence interval (Cl) 0.7-1.9); Bitot's spots were seen in 0.4% (95% Cl 0.1-1.0); 12.7% (95% Cl 9.9-15.5) showed deficient serum retinol levels (less than 0.35 mumol/liter). Of the children aged 1-8 years, 9.6% (95% Cl 7.8-11.4) showed deficient serum retinol levels. In the rural area, the prevalence of night blindness, Bitot's spots, and deficient serum retinol levels indicates a problem of public health importance according to World Health Organization criteria.

Intestinal helminths and xerophthalmia in Nepal. A case-control study.

The study reports on 25 cases of xerophthalmia among children 6-120 months of age and single controls for which faecal egg counts were available as proxy for hookworm and Ascaris lumbricoides infection. The selection of cases and controls was performed by ophthalmic assistants. Controls were healthy children matched for sex, age, and neighbourhood of residence. Faecal analyses were performed by Kato thick-smear technique, recording the number of eggs of hookworm and A. lumbricoides. The xerophthalmia cases had a significantly higher prevalence (P < 0.05) and intensity (P < 0.01) of infection, as expressed by the presence and number of A. lumbricoides eggs per gram of faeces, respectively, compared with the control group. Hookworm eggs were not detected in the faecal specimens of any of the cases or controls. This study demonstrates the importance of A. lumbricoides as a risk factor for ocular signs of vitamin A deficiency. Reduction of prevalence and intensity of A. lumbricoides infection may reduce the incidence of xerophthalmia in the community with its potential sequels of blindness, morbidity, and mortality.

Prevalence of xerophthalmia in relation to nutrition and general health in preschool-age children in three regions of Tanzania.

Integrated nutrition/health surveys were carried out in Mbeya, Iringa and Kagera Regions in Tanzania in which a total of 12,880 children were examined for the presence of xerophthalmia. Xerophthalmia was found to be a problem of public health significance in two of the three regions surveyed where the prevalence of active corneal xerophthalmic lesions was above the criteria set by WHO. Because of clustering of the children with Bitot's spots, corneal xerosis/ulceration and corneal scarring, only certain villages or groups of villages could be regarded as areas where xerophthalmia is a problem. The results of the ophthalmological examinations are discussed in relation to the nutritional status of the children as measured by anthropometric indices, serum levels of retinol-binding protein and prealbumin, haematological parameters, and vaccination status.

Xerophthalmia in malnourished Sudanese children.

Two hundred and thirteen Sudanese children (4-60 months old) with malnutrition were examined for signs of xerophthalmia. Sixty-three (29%) of these children were found to have varying stages of xerophthalmia. These included 35 (56%) patients with conjunctival xerosis, 12 (19%) with Bitot's spots, seven (11%) with corneal xerosis, seven (11%) with corneal ulceration and two (3%) with corneal scar. Direct questioning of the parents of these children revealed evidence of night blindness in nine (4%) of all patients. All nine patients had signs of xerophthalmia which showed good response to vitamin A therapy.

Malnutrition and xerophthalmia in rural communities of Ethiopia.

OBJECTIVE: To determine the level of malnutrition and xerophthalmia in pre-school children. DESIGNS: Non-randomised community based study. SETTINGS: Four different administrative regions: Harari, Tigray, Southern Nation Nationalities and people region (SNNPR) and Oromiya, with different eco-zones, were studied from May to June 1996. SUBJECTS: Fifteen thousand and eighty seven children, aged between six and 71 months, examined for clinical symptoms and signs of xerophthalmia. Anthropometry and blood samples were taken from every 20 children (n = 634) of same age, for serum retinol and nutritional determination. INTERVENTION MEASURES: Disease targeted approach of vitamin A supplementation was employed in the regions. RESULTS: The overall prevalence rates of night blindness and Bitot's spots exceeded WHO cut-off point for xerophthalmia as a public health problem, with higher prevalence rates in males (53%) than females (26%). The proportion of children with deficient serum retinol concentrations (SRC), and Bitot's spot were observed to be higher in Oromiya and Harari regions followed by Tigray, than SNNPR administrative regions. Most of the affected children were aged between 36 and 72 months. The greatest low SRC was also observed in the same age group of children in all regions. There was higher prevalence rate of stunting (60.1%) than wasting (12.2%) with an additional (8.8%) of children both stunted and wasted. The proportion of stunted children was high in Tigray followed by Oromiya, SNNPR and Harari regions. CONCLUSION: The high level of stunting and Bitot's spot, together with the low level of serum retinol concentrations found in these regions, indicates the need to strengthen this intervention strategy further with universal vitamin A capsule distribution, nutrition education and promotion of horticulture activities.
