Common alpha-thalassemia deletions in transfusion-dependent thalassemia patients in the Southeast Asia region of Myanmar.

Screening of 3 common alpha-thalassemia (thal) deletions (-alpha3.7, -alpha4.2 and --SEA) in Southeast Asia was done by polymerase chain reaction in 170 unrelated Myanmar thal patients receiving transfusions. Thal deletions were detected in 27 patients (15.9%) as: (1) alpha-thal-2 (-alpha3.7/alphaalpha) in 12 heterozygous or hemoglobin (Hb) E-beta-thal cases; (2) alpha-thal-1 in 7 patients (2-alpha3.7/-alpha3.7 and 5 --SEA/alphaalpha); and (3) Hb H (-alpha3.7/--SEA) in 8 patients. The latter 15 alpha-thal-1 and Hb H patients had no beta-thal mutations and represented 8.8% of the overall patients seeking transfusion for refractory anemia in Myanmar. This is the first description of alpha-thal in Myanmar from the molecular aspect, and its clinical and racial heterogeneity are described and discussed.

Investigation of small-intestinal transit time in normal and malnourished children.

We aimed to establish whether there was a variation in orocecal transit time (OCTT) in Myanmar children and whether shortened transit time correlated with malnutrition. OCTT was measured in 90 healthy Myanmar children aged 1-5 years, using the hydrogen breath test (10g in 10% aqueous solution). The relationships between OCTT, sex, age, and malnutrition status were assessed. OCTT for 1 to 5-year old children was 90.2 +/- 20min (mean +/- SD). There was no significant difference in mean OCTT between boys and girls, breast-fed and weaned children, malnourished and non-malnourished children. There was also no difference between age groups (1-2 years, 2-3 years, 3-4 years, and 4-5 years), and no correlation was found between age and orocecal transit time. The assessment of OCTT using the lactulose breath hydrogen test was found to be feasible and acceptable in the field setting. The OCTT of Myanmar children with rice as a staple food is similar to that of children from developed countries having a different diet, and no shortening of transit time was demonstrated in children with malnutrition.

Serum cortisol levels in children with dengue haemorrhagic fever.

Dengue Haemorrhagic Fever (DHF) is a serious and often fatal paediatric problem in Myanmar. Acute and convalescent serum cortisol levels were measured in 62 children with dengue infection to study cortisol sufficiency in this disease. Twenty-six children with non-dengue acute viral infection were also included as controls. In acute stage, highest mean serum cortisol level (655.4 +/- 72.18 nmol/l) was observed in DHF cases presenting with shock, followed by DHF non-shock cases (640.56 +/- 74.58 nmol/l) and dengue fever cases (617.2 +/- 75.38 nmol/l). Cases with DHF had significantly higher serum cortisol level (P < 0.05) than in controls (444.41 +/- 59.71 nmol/l). In cases of DHF, mean serum cortisol level during the acute stage was found to be significantly two-fold higher than the convalescent stage. We found no cortisol insufficiency in cases of dengue haemorrhagic fever during acute and convalescent stages of illness.

High-calorie, rice-derived, short-chain, glucose polymer-based oral rehydration solution in acute watery diarrhea.

In this study, we have compared the effects of the World Health Organization oral rehydration solution (WHO ORS) and an ORS containing short polymers of glucose (Amylyte ORS) at a high caloric density (five times) and comparable osmolality, on stool output, duration of diarrhea, weight gain and fluid and electrolyte balance, in randomized, open-labeled, controlled clinical trials in five centers. A total of 198 male children (4 months to 10 years) with acute diarrhea ( <72 h after onset) were assigned by random allocation to either WHO ORS or Amylyte ORS at five centers in Asia. Children were stratified according to grade of dehydration (mild, moderate or severe) and the initial purging rates during the first 6 h (low ( < 2 ml/kg/h), moderate (2-5 ml/kg/h) and high ( > 5 ml/kg/h) purgers). The clinical characteristics of the children in the two treatment groups were comparable. Amylyte ORS reduced stool volumes significantly in children with severe dehydration (285.4 +/- 74.2 versus 75.5 +/- 20.0 ml/kg; p < 0.05) and in children with a high initial purging rate (200.3 +/- 42.8 versus 130.5 +/- 9.1 ml/kg; p < 0.05). This was accompanied by a significant (276.4 +/- 14.6 versus 227.6 +/- 11.8 ml/kg; p < 0.01) reduction in ORS requirements in the Amylyte ORS treated group, the effect being greatest in children with severe dehydration (491.5 +/- 108.5 versus 155.7 +/- 27.3 ml/kg; p < 0.01) or high initial purging rates (394.2 +/- 66.2 versus 316.8 +/- 34.8 ml/kg; p < 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)

Thermophilic amylase-digested rice-electrolyte solution in the treatment of acute diarrhea in children.

OBJECTIVE: To compare the efficacy of an oral rehydration solution (ORS) containing short polymers of glucose derived from rice (Amylyte-ORS) and five times the caloric density of current ORS to the standard glucose-ORS (World Health Organization [WHO] = ORS) in the treatment of acute diarrhea in children. METHODS: The rice ORS (Amylyte-ORS) was obtained by adding thermophilic amylase (252,500 MW units) and salts (1.5 g NaCl, 600 mg KCl, and 150 mg CaCl2) to 100 g rice and boiling for 10 minutes in 500 mL water. This yields 250 mL Amylyte-ORS, which contains 92% to 96% short-chain glucose polymers, three to nine molecules in length, and provides 425 kcal/L, compared to 80 kcal/L for the WHO-ORS. One hundred forty-four male children, 4 months to 3 years of age, presenting with acute diarrhea and mild, moderate, or severe dehydration, were assigned by random allocation to receive either WHO-ORS or Amylyte-ORS. Data from 127 children were analyzed (57 received the WHO-ORS and 70 the Amylyte-ORS). Two children given Amylyte-ORS and 15 given the WHO-ORS were not included in the analysis because of improperly collected data or lost urine or fecal specimens. None were given antibiotics during the study. Free water and feeding were allowed after the children were rehydrated. RESULTS: The clinical characteristics of the children in the two treatment groups were comparable. Five children who received the WHO-ORS and three children given Amylyte-ORS were treatment failures. Amylyte-ORS reduced diarrhea duration by 15% (41.4 +/- 2.5 vs 34.7 +/- 1.8 hours; P < .03) compared to the WHO-ORS, regardless of the severity of dehydration. In the Amylyte-treated group, ORS requirements were significantly less (234 +/- 15.2 vs 295 +/- 17.6 mL/kg; P < .01) and weight gain was significantly more (367.7 +/- 45.1 vs 199.2 +/- 38.2 g; P < .01) than in those given the WHO-ORS. The net intestinal fluid balance and total body fluid balance were similar in the two groups. CONCLUSIONS: Amylyte-ORS effectively rehydrates children with acute diarrhea, reduces diarrhea duration, decreases ORS requirements, and improves weight gain compared to the WHO-ORS.

A prospective study on defecation frequency, stool weight, and consistency.

It has been commonly believed that children in developing countries pass stools that are very different from those of developed countries. A community based study on defecation frequency, stool weight, and consistency was conducted in a cohort of 300 Myanmar (Burmese) children aged 1 to 4 years. Most (80.3%) children opened their bowels daily and none passed more than three stools a day. The mean (SD) defecation frequency was 6.98 (1.94) times a week and total stool weight was 596 (221) g a week. The majority (61%) of children passed soft stools. At all ages, there was no significant difference in the defecation frequency, stool weight, and consistency between boys and girls, those on adult style diet and those partially weaned, and between age groups.

Comparison of glucose/electrolyte and maltodextrin/glycine/glycyl-glycine/electrolyte oral rehydration solutions in acute diarrhea in children.

Male children (N = 101) 6-35 months of age presenting with acute watery diarrhea for less than 48 h at home before hospitalization were admitted into a randomized, double-blind clinical trial. Fifty-one children were treated with standard oral rehydration solution (ORS) (World Health Organization [WHO] formulation containing citrate) and 50 were treated with an improved ORS formulation (containing, in addition to the standard formula, 20 g maltodextrin instead of glucose, and 4 g glycine and 4 g glycyl-glycine). None were given antibiotics. No i.v. infusions were given. Rotavirus was detected by enzyme-linked immunosorbent assay in stools of 43 children. Clinical characteristics of children in the two treatment groups were comparable. Improved ORS did not produce significant reduction in the volume of diarrhea stools. Children given improved ORS had greater weight gain than that observed in children treated with standard ORS, but the differences were not statistically significant except at the end of the first 24 h. Among children with rotavirus diarrhea, no significant differences were observed between the 23 children who received improved ORS and the 20 who received standard ORS.
