Clinico-microbiological and Risk Factor Analysis of Strongyloides stercoralis Infections in South India

Strongyloides stercoralis is a soil-transmitted nematode infection. It is implicated in causing hyper infection syndrome in immunosuppressed patients. This infection can also present without symptoms. The study aims to analyze the demographic data and risk factors associated with acquiring this infection and detectStrongyloides stercoralis in the stool sample by microscopy and modified agar plate culture. Combining microscopy and culture can facilitate detecting the infection in cases of low worm burden. Evaluation of socio-demographic information and risk factors will help in implementing control measures. A total of 986 stool samples were received. All the samples were examined by saline and Iodine mount examination. All the stool samples were cultured by the modified agar plate method. The risk factors, patient demographic details and clinical features were analyzed for significant association using the Chi-square test and a p-value < 0.05 was considered significant) by quick calls graph pad software. The overall prevalence of Strongyloides stercoralis infection was 22(1.23%), and all these cases were diagnosed on stool examination by the demonstration of rhabditiform larva ofStrongyloides stercoralis and adult females by modified agar plate culture. The positivity for Strongyloides larva was high among males, patients from rural areas and individuals working in agricultural settings. There was a significant association between walking barefoot and the demonstration of the larva. Patients presenting from endemic regions, even with vague, nonspecific gastrointestinal symptoms, especially with risk factors like Diabetes mellitus, should be screened for this infection and treated. Awareness, proper hygiene practices, and appropriate treatment are necessary to prevent this soil-transmitted helminthic infection

Red-Complex Bacterial Levels in Pregnant Women With Preeclampsia and Chronic Periodontitis

ABSTRACT: Objectives: The presence of red-complex bacteria (RCB) has been associated with the occurrence of not only periodontal disease but also other systemic diseases, thereby potentiating an oral–systemic relationship. This study aimed to explore the levels of periodontal RCB in pregnant preeclamptic women with periodontal disease, potentiating the pathophysiology of a bacterial association in both periodontitis and preeclampsia. Methods: Six hundred pregnant women (aged 20 to 35 years) in their third trimester were selected and divided into 3 groups comprising a control group (systemically and periodontally healthy pregnant women), group A (preeclamptic women with chronic periodontitis), and group B (preeclamptic women without chronic periodontitis). Demographic variables and periodontal parameters were recorded. Other variables such as systolic blood pressure (SBP) and diastolic blood pressure (DBP) and the urine protein content were also estimated. RCB, namely Porphyromonas gingivalis (Pg), Treponema denticola (Td), and Tenerella forsythia (Tf), were assessed in both subgingival plaque samples and placental samples of all the pregnant participants in the study. Results: The mean weight, mean body mass index, mean SBP, mean DBP, and mean urine protein content were significantly elevated in group A and group B when compared to the control group. Preeclamptic women with chronic periodontitis (group A) had higher levels of plaque index, probing pocket depth, bleeding on probing, and clinical attachment level as compared with the other groups. The numbers of the RCB were found to be elevated in group A, out of which Pg was found to be more prevalent. Conclusions: Our findings indicate that the periodontal indices, blood pressure, and urine protein content were found to be higher in preeclamptic women with periodontitis. Hence, reducing the periodontal bacterial load in pregnant women via good oral hygiene maintenance would further reduce the putative risk of adverse pregnancy outcomes including preeclampsia in these women
