Gut microbiota in hospitalized children under 5 years with acute infective gastroenteritis caused by virus or bacteria in a regional Peruvian hospital

ABSTRACTObjective: The main objective of this study was to describe the prevalence of 13 representative bacteria from the gut microbiota (GM) in stools samples from children under 5 years of age with acute infective gastroenteritis (AIG) as well as to describe clinical and demographic features from our study population.Results: The most commonly isolated bacteria from the GM were Firmicutes (63.2%) Bacteriodetes (62.4%), Lactobacillus (59.8%), Prevotella (57.3%), Proteobacterium (53.8%), regardless of the etiological agent responsible for the AIG. Interestingly, despite the high prevalence of Firmicutes, Bacteroidetes, Lactobacillus, and Prevotella across all samples, a visible reduction of these agents was observed especially among patients with a single bacterial infection or even bacteria – bacteria coinfections when compared to viral etiologies. Patients with exclusive or mixed breastfeeding registered the highest amount of gut microbiota bacteria, in contrast to infants who received formula or were not breastfed.

Genotype-specific prevalence of human papillomavirus infection in asymptomatic Peruvian women: a community-based study

BMC Research Notes (2021)

Juana del Valle-Mendoza Lorena Becerra-Goicochea Miguel Ángel Aguilar-Luis Luis Pinillos-Vilca Hugo Carrillo‐Ng

Abstract Objective To determine the general and genotype-specific prevalence of HPV and to identify potential risk factors for the infection in a population-based screening of Peruvian women. Results A total of 524 samples were analyzed by PCR and a total of 100 HPV positive samples were found, of which 89 were high-risk, 19 were probably oncogenic, 9 were low-risk and 27 other HPV types. The 26–35 and 36–45 age groups showed the highest proportion of HPV positive samples with a total of 37% (37/100) and 30% (30/100), respectively. Moreover, high-risk HPV was found in 33.7% of both groups and probably oncogenic HPV in 52.6% and 31.6%, respectively. High-risk HPV were the most frequent types identified in the population studied, being HPV-52, HPV-31 and HPV-16 the most commonly detected with 17.6%, 15.7% y 12.9%, respectively. Demographic characteristics and habits were assessed in the studied population. A total of 62% high-risk HPV were detected in married/cohabiting women. Women with two children showed the highest proportion (33.8%) of high-risk HPV, followed by women with only one child (26.9%). Those women without history of abortion had a higher frequency of high-risk HPV (71.9%), followed by those with one abortion (25.8%).

Case report: Clitoromegaly as a consequence of Congenital Adrenal Hyperplasia. An accurate medical and surgical approach

Urology Case Reports (2018)

Augusto R. Fernández-Aristi André Taco-Masias Luis Montesinos-Baca

We present a case of a woman with a history of Congenital Adrenal Hyperplasia (CAH) diagnosed at the age of 12, who was referred to our unit for surgical treatment. Despite the initial diagnosis was an indirect inguinal hernia, it was a misdiagnosis. Once in our service, this was corrected into clitoromegaly secondary to CAH. Physical examination and imaging test discarded other abnormalities, such as secondary effects androgenization. Regarding surgical treatment, the techniques used were Spencer and Allen combined with Kumar, which are the most used for clitoroplasty but also less used in Peru.

Gut microbiota in hospitalized children with acute infective gastroenteritis caused by virus or bacteria in a regional Peruvian hospital

PeerJ (2020)

André Taco-Masias Augusto R. Fernández-Aristi Angela Cornejo‐Tapia Miguel Ángel Aguilar-Luis Luís J. del Valle

Acute infective gastroenteritis (AIG) is a leading cause of mortality in children worldwide. In Peru, more than 40% of cases of AIG occurring in children under 5 years old. The disruption of the gut microbiota can increase risk for several health complications especially in patients with gastric infections caused by viruses or bacteria.The main objective of this study was to describe the prevalence of 13 representative bacteria from the gut microbiota (GM) in stools samples from children under 5 years of age with acute infective gastroenteritis.The most commonly isolated bacteria from the GM were Firmicutes (63.2% 74/117) Bacteriodetes (62.4%; 73/117), Lactobacillus (59.8%; 70/117), Prevotella (57.2%; 67/117), Proteobacterium (53.8%; 63/117), regardless of the etiological agent responsible for the AIG. Interestingly, despite the high prevalence of Firmicutes, Bacteroidetes, Lactobacillus and Prevotella across all samples, a visible reduction of these agents was observed especially among patients with a single bacterial infection or even bacteria-bacteria coinfections when compared to viral etiologies. Patients with exclusive or mixed breastfeeding registered the highest amount of gut microbiota bacteria, in contrast to infants who received formula or were not breastfed.
