ABSTRACT. The problem of detecting and diagnosing abdominal tuberculosis (TB) remains difficult. Recently in Ukraine there has been an increase in extrapulmonary TB, including abdominal TB. In modern conditions, this localization of TB is a manifestation of a generalized process in HIV-infected people. The most commonly diagnosed lesions of the lymphatic system and the peritoneum. The liver and spleen in abdominal TB is affected in every third case (32.3 %). In most patients, TB of the abdominal organs develops as a result of lymph-hematogenous dissemination from the primary focus, progresses through contact from the mesenteric lymph nodes to the peritoneum and intestines. According to statistics, TB of the mesenteric lymph nodes is most often diagnosed (70 %), the ileocecal region and the peritoneum are affected in 12 % of cases. The clinical picture of abdominal TB is polymorphic, there are no pathognomonic symptoms, therefore, the diagnosis of damage to the abdominal organs is the most difficult in the field of phthisiology. Diagnostic methods that are used: X-ray examination of the small intestine with a contrast agent, irrigoscopy, ultrasonography, computed tomography (CT), laparoscopy and laparotomy with sampling of material for morphological and bacteriological researches. The diagnostic value of CT with bolus enhancement is quite high: sensitivity is 95 %, specificity is 67.5 %. Given the difficulty of confirming the diagnosis of TB, in the case when the diagnosis is not confirmed culturally or histologically, and there is a reasonable suspicion of a specific lesion, which is based on clinical, endoscopic and radiological data, it is recommended to prescribe empirical treatment. Most patients respond positively to anti-TB treatment within 2 weeks. A clinical case of abdominal TB in an HIV-infected patient is described in this article.

Ascaridosis is a common parasitic infection among children that can cause various complications. The aim of the study was to determine the condition of the abdominal organs according to ultrasound diagnostics in children with a confirmed diagnosis of ascariasis. 45 children with ascariasis and 35 children of the control group were examined. It was determined that in most cases in the group with ascariasis the following changes are recorded: an increase in the “brightness” of the liver texture, an increase in the size of mesenteric lymph nodes, and the presence of a gastroesophageal reflux. Key words: ascariasis, children, ultrasound diagnostics, liver, mesenteric lymph nodes, hydrosonography, stomach, esophagus.

AbstractIntestinal Foxp3+ regulatory T cell (Treg) subsets are crucial players in tolerance to microbiota-derived and food-borne antigens, and compelling evidence suggests that the intestinal microbiota modulates their generation, functional specialization, and maintenance. Selected bacterial species and microbiota-derived metabolites, such as short-chain fatty acids (SCFAs), have been reported to promote Treg homeostasis in the intestinal lamina propria. Furthermore, gut-draining mesenteric lymph nodes (mLNs) are particularly efficient sites for the generation of peripherally induced Tregs (pTregs). Despite this knowledge, the direct role of the microbiota and their metabolites in the early stages of pTreg induction within mLNs is not fully elucidated. Here, using an adoptive transfer-based pTreg induction system, we demonstrate that neither transfer of a dysbiotic microbiota nor dietary SCFA supplementation modulated the pTreg induction capacity of mLNs. Even mice housed under germ-free (GF) conditions displayed equivalent pTreg induction within mLNs. Further molecular characterization of these de novo induced pTregs from mLNs by dissection of their transcriptomes and accessible chromatin regions revealed that the microbiota indeed has a limited impact and does not contribute to the initialization of the Treg-specific epigenetic landscape. Overall, our data suggest that the microbiota is dispensable for the early stages of pTreg induction within mLNs.

ABSTRACT Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly prescribed for a variety of inflammatory conditions; however, the benefits of this class of drugs are accompanied by deleterious side effects, most commonly gastric irritation and ulceration. NSAID-induced ulceration is thought to be exacerbated by intestinal microbiota, but previous studies have not identified specific microbes that contribute to these adverse effects. In this study, we conducted a culture-independent analysis of ∼1,400 bacterial small-subunit rRNA genes associated with the small intestines and mesenteric lymph nodes of rats treated with the NSAID indomethacin. This is the first molecular analysis of the microbiota of the rat small intestine. A comparison of clone libraries and species-specific quantitative PCR results from rats treated with indomethacin and untreated rats revealed that organisms closely related to Enterococcus faecalis were heavily enriched in the small intestine and mesenteric lymph nodes of the treated rats. These data suggest that treatment of NSAID-induced ulceration may be facilitated by addressing the microbiological imbalances.
