AbstractObjectiveWe conducted a cluster-randomized controlled trial to assess the efficacy of a cereal made from caterpillars, a micronutrient-rich, locally available alternative animal-source food, on reducing stunting and anaemia in infants in the Democratic Republic of Congo.DesignSix-month-old infants were cluster randomized to receive either caterpillar cereal daily until 18 months of age or the usual diet. At 18 months of age, anthropometric measurements and biological samples were collected.SettingThe rural Equateur Province in the Democratic Republic of Congo.SubjectsOne hundred and seventy-five infants followed from 6 to 18 months of age.ResultsStunting was common at 6 months (35 %) and the prevalence increased until 18 months (69 %). There was no difference in stunting prevalence at 18 months between the intervention and control groups (67 % v. 71 %, P=0·69). Infants in the cereal group had higher Hb concentration than infants in the control group (10·7 v. 10·1 g/dl, P=0·03) and fewer were anaemic (26 v. 50 %, P=0·006), although there was no difference in estimates of body Fe stores (6·7 v. 7·2 mg/kg body weight, P=0·44).ConclusionsSupplementation of complementary foods with caterpillar cereal did not reduce the prevalence of stunting at 18 months of age. However, infants who consumed caterpillar cereal had higher Hb concentration and fewer were anaemic, suggesting that caterpillar cereal might have some beneficial effect. The high prevalence of stunting at 6 months and the lack of response to this micronutrient-rich supplement suggest that factors other than dietary deficiencies also contribute to stunting.

Abstract Introduction: The detection of intrathecal IgA synthesis (IAS) in multiple sclerosis (MS) is cumbersome, for this reason, we developed a highly sensitive assay to assess it in MS. Methods: 151 MS patients and 22 controls with different neurological diseases were recruited. IgA concentration was analyzed by ELISA. Oligoclonal IgA bands to detect IAS were determined by a new ultrasensitive assay based on isoelectrofocusing (IEF). Results: Most individuals showed an IgA concentration within normal range in serum samples (95.95%) but 38.41% of individuals had a low IgA concentration in the cerebrospinal fluid (CSF), with no significant differences observed between MS and control groups, neither in CSF nor in serum. The new IEF was more sensitive than those previously described (0.01 mg/dl of IgA), and clearly identified patients with and without IAS, that was not related with IgA concentration. MS patients showed higher percentage of IAS (43.00%) than the control group (18.20) (p = 0.035), because the incidence was especially higher in MS patients with clinically isolated syndrome (CIS, 66.00%). Conclusions: Intrathecal IgA synthesis is observed more frequently in MS patients than in other neurological diseases, and with higher incidence than assumed in the past.

Abstract Abstract 4078 Poster Board III-1013 Introduction Osteoporosis is an important cause of morbidity in patients with β thalassemia major. Several genes are thought to be involved in the pathogenesis of osteoporosis. Collagen type I alpha 1 (COLIA1) is one of the most prominent candidate genes, which has been consistently associated with osteoporosis in different populations. Polymorphism at the Sp1 binding site within a key regulatory region of COLIA 1 has been reported to be associated with susceptibility to osteoprotic fractures. Our objective was to detect the allelic distribution of COLIA1 gene in beta thalassemia patients and its relation to bone mineral density (BMD). Patients and methods The study included 25 beta thalassemia major patients (12-28 years, mean = 18.12±5.077 years) and 20 controls (mean age = 23.05±2.3 years) with no family history of thalassemia. Anthropometric measurements were done to all patients .Femoral and lumbar BMD was measured in all patients and control groups using dual energy absorbiometry (DXA). Assessment of the COLIA1 genotypes (SS, Ss, ss) and G/T polymorphism were done using PCR amplification and restriction enzyme digestion (Bal1) of DNA amplified products to thalassemic patients and control groups. Results High prevalence of growth retardation was observed in β thalassemia major patients in the form of short stature (36%), truncal shortening (48%) and under weight (8%). Osteopenia and osteoporosis were detected in 68% of the thalassemia patients with a highly significant lower lumbar and femoral BMD compared to controls (P<0.01) (Table 1). There was a non significant difference between genders regarding BMD, significant negative correlation was observed between long duration of desferroxamine (DFO) intake and low femoral and lumbar BMD (R=-0.571& P<0.01,R=-0.571&P<0.05) in β thalassemia patients. A negative correlation was observed between ferritin level and fat free mass% (FFM%) in thalassemic patients (R=-0.48& P<0.05) and low lumbar BMD in female patients (R=-0.55& P<0.05). There was a positive correlation between age of starting DFO and decreased sitting height in male patients (R=0.74&P<0.01). In the thalassemic group, frequency of COLIA1 alleles was S (94%), s (6%), 12% showed the G/T polymorphism while 88% had the G/G polymorphism (Table 2). Non significant difference was observed in most of the parameters between the 2 different groups of polymorphism. In the control group allele frequencies were S (87.5%) and s (12.5%), G/T polymorphism was present in 25%.and G/G in 75%. No association was detected between COLIA1 gene polymorphism and BMD in the lumbar spine or in femur bone in the thalassemia patients (P>0.05) while the s allele was associated with femoral and lumbar BMD in the control group (P<0.05, P<0.01) (Table 3). Conclusion High prevalence of growth impairment, osteopenia and osteoporosis in our β thalassemia major patients. Desferroxamine duration therapy was related to osteoporosis in our patients. The absence of association between BMD and COLIA 1 polymorphism and the low frequency of s allele in our thalassemic group may be due to the small sample size of the thalassemia patients together with the fact that BMD is determined by a variety of genetic and environmental factors. Further studies including larger number of patients are needed to evaluate these findings. Disclosures: No relevant conflicts of interest to declare.

ABSTRACT Objectives: To investigate the association between third molar agenesis and pattern of impaction, missing teeth, and peg-shaped lateral incisor with palatal canine displacement (PDC). Materials and Methods: The pretreatment orthodontic orthopantomograms of 438 patients (122 males and 316 females) diagnosed with PDC were included. A total of 338 patients with normally erupted canines who had a preexisting radiograph as part of their orthodontic treatment (125 males and 313 females) served as controls. Orthopantomograms were evaluated for missing third molars, third molar eruption status, and type of impaction, third molar spaces, third molar width, and angulation. Results: In the PDC group, at least one third molar was missing in 48% and 19% in the upper and lower arches, respectively. Also, 38% and 67% of PDC patients had at least one third molar impaction in the upper and lower arches, respectively. The difference between the PDC and control groups was significant for both missing and impacted third molars (P < .001 for each). The most common type of third molar impaction in the upper arch was vertical and distoangular in the PDC and control groups, respectively. Upper and lower third molar width and spaces were reduced in PDC patients when compared with the control group (P < .001). In PDC patients, missing teeth and peg-shaped lateral incisors were recorded in 5.6% and 9.1%, respectively. Conclusions: PDC patients showed a high prevalence of third molar agenesis and impaction. Upper and lower third molar width and space were reduced in the PDC patients. There were no significant associations between tooth agenesis (other than third molars) and the PDC anomaly.

Abstract Background: Kashin-Beck disease (KBD) is an endemic osteoarticular disease, which has had a high prevalence in China. Osteoarthritis (OA) is the dominating proportion of osteoarticular disease. The objective of this study is to investigate the expression of enzymes involved in synthesis and modification of chondroitin sulfate (CS) in knee cartilage tissue of osteoarthritis (OA) and Kashin-Beck disease (KBD) patients. Methods: Knee articular cartilage samples were obtained from 18 age and gender matched donors. Hematoxylin & eosin staining, toluidine blue staining, and immunehistochemical staining were performed to estimate the expression level and localization of aggrecan and the enzymes associated with CS synthesis and modification (FAM20B, GalT-II, EXTL2). Rank-based analyses of variance (ANOVA) test was used for the multiple comparisons of discrepancy in the positive staining rate among the KBD, OA, and control groups. Results: Decreased proteoglycans were observed in OA and KBD compared with control group. In line with these expression trends, the positive staining rates of aggrecan were lower in KBD and OA group than control group. The positive staining rates of CS chain modifying enzymes FAM20B, GalT-II, and EXTL2 were also decreased in OA and KBD group. Conclusion: In conclusion, our study uncovered that the enzymes involved in synthesis and modification of CS can influence the expression synthesis of aggrecan and CS. Further investigation of these enzymes can provide new theoretical and experimental targets for OA and KBD pathogenesis studies.

Abstract Background Concerning the high prevalence of anxiety disorders and joint hypermobility in children and the lack of related studies in this age group, we aimed to assess the relationship between the prevalence of hypermobility and anxiety disorders in children. MethodsIn this case-control study, 93 children ages 8-15 years with anxiety disorders referring to the Child and Adolescent Psychiatry Clinic of Mofid Children’s Hospital, Tehran, Iran, during 2018, were enrolled. The control group consisted of 100 age and sex-matched children without anxiety disorders. Anxiety was evaluated using the Spence Children Anxiety Scale (SCAS). The diagnosis of generalized joint hypermobility was done based on Beighton and Shiari-Javadi criteria. Results Based on Beighton’s diagnostic criteria 52.7% of the children in the case group and 16% of the children in the control group had generalized joint hypermobility. Moreover, based on Shiari-Javadi criteria, 49.5% and 13% of the children in the case and control groups had generalized joint hypermobility, respectively. Moreover, the internal correlation between the two criteria was 0.91 showing almost complete compatibility between the two (P<0.001). Age was a risk factor that could predict hypermobility in these children. Other variables such as sex, severity, and type of anxiety disorders, and ADHD, were not predictors of hypermobility syndrome. Conclusion The prevalence of hypermobility was three times higher in children with anxiety disorders and only age was a predictor for the possibility to suffer from generalized joint hypermobility in these children.

Objective To compare periodontal conditions in children with and without cleft. Design Clinical examinations and microbiological analysis of 57 selected children, including 30 with unilateral complete cleft lip and palate (experimental group) and 27 without clefts (control group). Setting Hospital of Rehabilitation of Craniofacial Anomalies (HRCA) in Bauru, Sao Paulo, Brazil. Patients, Participants All children examined were healthy and between the ages of 5 and 6 years. Results The mean plaque index (PI) in the experimental group was higher (1.82 ± 0.3) than in the control group (1.63 ± 0.38), although this difference was not statistically significant. The mean gingival index (GI) in the experimental group (1.82 ± 0.38) was found to be significantly higher (p < .05) than that of the control group (0.79 ± 0.33). The cleft area in the experimental group, with a mean PI of 2.04 ± 0.58 and mean GI of 1.11 ± 0.26, compared with the posterior area, with a mean PI of 1.74 ± 0.37 and mean GI of 1.04 ± 0.26, showed a statistically significant difference only in the PI. Most of the children in both experimental and control groups presented a moderate PI degree (73.33% and 81.48%, respectively) and a high prevalence of mild gingivitis (53.33% and 70.37%, respectively). Analysis of the organisms showed that Prevotella nigrescens was detected in 16.67% of the experimental group and 11.11% of the control, whereas Porphyromonas gingivalis and Treponema denticola were not detected. Conclusion Children with clefts showed greater gingival inflammation, despite the same amount of plaque and prevalence of microorganisms.
