Microbiological, lipid and immunological profiles in children with gingivitis and type 1 diabetes mellitus

Abstract Objective The aim of this study was to compare the prevalence of periodontal pathogens, systemic inflammatory mediators and lipid profiles in type 1 diabetes children (DM) with those observed in children without diabetes (NDM), both with gingivitis. Material and methods Twenty-four DM children and twenty-seven NDM controls were evaluated. The periodontal status, glycemic and lipid profiles were determined for both groups. Subgingival samples of periodontal sites were collected to determine the prevalence of periodontal microorganisms by PCR. Blood samples were collected for IL-1-β, TNF-α and IL-6 analysis using ELISA kits. Results Periodontal conditions of DM and NDM patients were similar, without statistical differences in periodontal indices. When considering patients with gingivitis, all lipid parameters evaluated were highest in the DM group; Capnocytophaga sputigena and Capnocytophaga ochracea were more prevalent in the periodontal sites of DM children. “Red complex” bacteria were detected in few sites of DM and NDM groups. Fusobacterium nucleatum and Campylobacter rectus were frequently found in both groups. Similar levels of IL-1-β, TNF-α and IL-6 were detected in DM and NDM children. Conclusion Clinical and immunological profiles are similar between DM and NDM children. The presence of Capnocytophaga sputigena and Capnocytophaga ochracea were associated with gingivitis in DM children.

Dyspeptic symptoms in patients with type 1 diabetes: endoscopic findings, Helicobacter pylori infection, and associations with metabolic control, mood disorders and nutritional factors

Objectives To evaluate, in a group of patients with long-standing type 1 diabetes (DM1), an association of dyspepsia symptoms with: changes in the gastroduodenal mucosa, infection by Helicobacter pylori, glycemic control, and psychological and nutritional factors. Subjects and methods A total of 32 patient with DM1 were studied (age: 38 ± 9 years; females: 25; diabetes duration: 22 ± 5 years). All patients answered a standardized questionnaire for the evaluation of gastrointestinal symptoms and underwent upper gastrointestinal endoscopy, with gastric biopsies for the evaluation of Helicobacter pylori infection. The presence of anxiety and depression was evaluated by the HAD scale. Nutritional parameters were BMI, arm and waist circumference, skinfold measurement, and body fat percentage. Results Upper endoscopy detected lesions in the gastric mucosa in 34.4% of the patients, with similar frequency in those with (n = 21) and without dyspepsia (n = 11). The patients with dyspepsia complaints showed greater frequency of depression (60% vs. 0%; p = 0.001), higher values for HbA1c (9.6 ± 1.7 vs. 8.2 ± 1.3%; p = 0.01) and lower values for BMI (24.3 ± 4.1 vs. 27.2 ± 2.6 kg/m2; p = 0.02), body fat percentage (26.6 ± 6.2 vs. 30.8 ± 7.7%; p = 0.04), and waist circumference (78.7 ± 8 vs. 85.8 ± 8.1 cm; p = 0.02). No association was found between the symptoms and the presence of Helicobacter pylori. Conclusions Dyspepsia symptoms in patients with long-standing DM1 were associated with glycemic control and depression, and they seem to negatively influence the nutritional status of these patients. .

Determinants of periodontopathogens in microbiological monitoring of diabetic patients with periodontitis

To determine and analyze the frequency of periodontopathogens in microbiological monitoring of diabetic patients with periodontitis. This cross-sectional study included 352 diabetic patients with periodontitis who were registered at Riyadh Armed Forces Hospital, King Faisal Specialist Hospital and Research Centre, King Abdul Aziz Medical City, Naval Base Hospital, and Sultan Bin Adulaziz Humanitarian City, Riyadh, Kingdom of Saudi Arabia from July 2004 to August 2008. Microbiological analysis comprised the detection of Bacteroides forsythus [Bf], Aggregatibacter actinomycetemcomitans [Aa], Porphyromonas gingivalis [Pg], and Prevotella intermedia [Pi] by polymerase chain reaction method. The mean age of patients was 54.4 +/- 0.67 [range: 21-80 years]. There were 214 [61%] males and 138 [39%] females. Among the study population, 36 [10%] had type 1, and 316 [90%] patients had type 2 diabetes. The results showed that 55.6% of patients had Bf, 51.7% had Az, 63.7% had Pg, and 6.1% had Pi. The frequencies of periodontopathogens were higher in males than females in all age groups. The risk of periodontopathogens Bf were found higher level in 41-50 age group, Aa in 51-60, Pg in 51-60, and Pi in 31-40 age groups. This study found that the frequencies of periodontal pathogens Bf, Aa, and Pg were higher than Pi in diabetic patients with periodontitis

Estudo da micobiota em conjuntiva sadia de diabéticos, residentes na área urbana da cidade de São Paulo - Brasil / Study of mycobiota in the healthy conjunctiva of diabetics who reside in the urban area of the city of São Paulo, Brazil

OBJETIVOS: Determinar a micobiota de conjuntiva sadia em indivíduos diabéticos, segundo tipo de diabetes, idade, sexo, tempo de doenca, tipo de tratamento e estádio da retinopatia. Estabelecer a micobiota anemófila nas salas de colheita. MÉTODOS: Estudo transversal de 803 diabéticos residentes na zona urbana de São Paulo - SP/Brasil. Foi usado para primo-isolamento o meio de cultivo ágar Sabouraud dextrose com cloranfenicol e para identificacão dos fungos filamentosos a chave de De Hoog. RESULTADOS: Dos diabéticos avaliados, 6,6 por cento (53/803) apresentavam diabetes tipo 1 e 93,4 por cento (750/803) tipo 2. Os cultivos positivos para fungos em conjuntiva de diabéticos foi 4,2 por cento (34/803), sendo 1,9 por cento (1/53) nos diabéticos tipo 1 e 4,4 por cento (33/740) nos diabetes tipo 2 (p=0,720). Não foi verificada associacão estatisticamente significante quanto à presenca ou não de isolamentos de fungos em relacão idade (p=0,575), sexo (p=0,517), tempo de doenca (p=0,633), tipo de tratamento (p=0,422) e estádio de retinopatia diabética (p=0,655) desses indivíduos. Todos os fungos identificados foram filamentosos: Aspergillus spp. representou 59,5 por cento (25/42) dos isolamentos sendo 47,6 por cento (20/42) Aspergillus niger. Ocorreu crescimento de fungos anemófilos do ar ambiente da sala, observando-se coincidências entre as espécies isoladas no ar e na conjuntiva. CCONCLUSÕES: Foi identificada presenca de micobiota em conjuntiva sadia de diabéticos, não havendo associacão entre a maior positividade de isolamentos fúngicos e o tipo de diabetes, idade, sexo, tempo de doenca, tipo de tratamento e estádio da retinopatia diabética. Nas salas de colheita foi identificada micobiota anemófila.

Oral carriage rate of Candida species in diabetic patients

It is well known that diabetes is one of the predisposing factors, which affect the oral carriage rate of Candida species, in this paper we try to study the size of this problem. A total of 340 oral swabs from diabetic patients [type l and 2], 67% females and 33% males taken, results show that 37.9% of those had isolates of Candida species older patients had higher carriage rate but is not significant statistically [P>0.05]. Females had higher carriage raw [P<0.0l] possibly due to hormonal difference no difference found between type 1 and 2 of diabetes [P>0.05]. Those with poor control had higher carriage rate than those with good control [P<0.01]. In this study we see that being diabetic, female, with poor control had high chance to had oral carriage of Candida especially of albicans type

Actinobacillus actinomycetemcomitans in Brazilian insulin-dependent individuals with diabetes mellitus

The prevalence of Actinobacillus Actinomycetemcomitans (Aa) in subgingival plaque specimens from 26 insulin-dependent diabetes mellitus patients, 11-25 years of age, was determined between January 1987 and December 1989. One hundred and thirty subgingival plaque samples were collected with sterile periodontal curettes. The specimens were weighed, diluted, inoculated on trypticase-soy-serum-bacitracin-vancomycin agar medium (TSBV) and incubated under microaerophilic conditions. Aa was isolated from 2.3//of healthy periodontal areas in these patients, while the microorganism was found in 12.5//of the sites with gingivitis and in 2.6//of the periodontal pockets examined. Although biochemical tests used for the characterization of Aa strains showed homogeneous results, different biotypes were isolated from one or more periodontal sites in the same patient

Estado de portador de Staphylococcus aureus en pacientes diabéticos

Estudio bacteriológico realizado en pacientes diabéticos insulino dependientes y no insulino dependientes que asisten al Patronato contra la Diabetes, en el período comprendido de Junio a Julio de 1987. Las infecciones causadas por Staphylococcus aureus han constitutido una muy seria preocupación para médicos y epidemiologos, por la gravedad que representan especialmente para diabéticos; en quiens se ha demostrado que el estado del portador es fuente de infección frecuente representado riesgo de diseminación para ellos y otros pacientes. (1) En este trabajo se investigaron 120 pacientes diabéticos, pudiéndose establecer que la frecuencia del estado portador varía significativamente en relación a los datos que se tienen de la población en general, que la presencia de Staphylococcus a nivel nasal es mayor en frecuencia los pacientes diabéticos insulinos dependientes (Tipo I) que en no dependientes, además que el patrón de susceptibilidad a los antimicrobianos varió notablemente entre un grupo y otro, la resistencia a las penicilinas G y a la oxacilina es dos veces mayor en cepas aisladas en pacientes insulino dependientes
