Abstract
Intestinal microbiota correction in the therapy of irritable bowel syndrome (IBS) is an important medical problem. We conducted a laboratory and pilot clinical trial to investigate the effect of autoprobiotic bacteria, indigenous bifidobacteria and enterococci isolated from faeces and grown on artificial media to use as personified food additives in IBS treatment. Convincing evidence of the clinical efficacy of autoprobiotic was demonstrated by the disappearance of dyspeptic symptoms. The microbiome of patients with IBS was compared to a group of healthy volunteers and changes in the microbiome after autoprobiotic use were detected by quantitative polymerase chain reaction and 16S rRNA metagenome analysis. The possibility of reducing opportunistic microorganisms in the treatment of IBS with autoprobiotics has been convincingly proven. The quantitative content of enterococci in the intestinal microbiota was higher in IBS patients than in healthy volunteers and increased after therapy. An increase in the relative abundance of genera Coprococcus, Blautia and a decrease in the relative abundance of Paraprevotella spp. were found at the end of therapy. A metabolome study which was performed by gas chromatography and mass spectrometry demonstrated an increase in the content of oxalic acid, a decrease of dodecanoate, lauric acid, and other metabolome components after taking autoprobiotics. Some of these parameters correlated with the relative abundances of Paraprevotella spp., Enterococcus spp., and Coprococcus spp. representative of the microbiome. Apparently, they reflected the peculiarities of metabolic compensation and changes in the microbiota. Therefore, the use of autoprobiotics for treatment of IBS may lead to a stable positive clinical effect, associated with compensatory changes in the intestinal microbiota, and accompanied by corresponding changes in metabolic processes in the organism.

Abstract
The optimal treatment for osteoarticular infection due to multidrug-resistant tuberculosis strains (MDR-OATB) remains unclear. This study aims to evaluate the diagnosis, management and outcome of MDR-OATB in France. We present a case series of MDR-OATB patients reviewed at the French National Reference Center for Mycobacteria between 2007 and 2018. Medical history and clinical, microbiological, treatment and outcome data were collected. Twenty-three MDR-OATB cases were reported, representing 3% of all concurrent MDR-TB cases in France. Overall, 17 were male, and the median age was 32 years. Six patients were previously treated for TB, including four with first-line drugs. The most frequently affected site was the spine (n = 16). Bone and joint surgery were required in 12 patients. Twenty-one patients (91%) successfully completed the treatment with a regimen containing a mean of four drugs (range, 2-6) for a mean duration of 20 months (range, 13-27). Overall, high rates of treatment success were achieved following WHO MDR-TB treatment guidelines and individualized patient management recommendations by the French National TB Consilium. However, the optimal combination of drugs, duration of treatment and role of surgery in the management of MDR-OATB remains to be determined.

Abstract
Objective: Little information is available about the etiology, pathophysiology, risk factors, and epidemiologic features of Bone Tuberculosis (Bone-TB). In this work, we present the epidemiological data about the Bone-TB in the Sultanate of Oman. Methods: Retrospectively, we identified and assessed those patients who were diagnosed with Bone-TB between January 2002 and December 2019 at Khoula Hospital. The following data were collected: demographics, clinical presentation, anatomical location, diagnosis, and treatment of the Bone-TB. Results: During the study period, 115 cases of Bone-TB were diagnosed. Males were affected more than females (57.4% and 42.6%, respectively). About 30% of Bone-TB cases were primary diagnosed in other organs particularly the lungs and then after disseminated to the bone. However, the Bone-TB was detected in hip, leg, hand, shoulder, and skull bones, the most detected Bone-TB was in spine (66% of cases). After vaccination the Bacillus Calmette–Guérin (BCG) strains were identified in the bones of eight babies. Tubercle bacilli were detected by Acid-Fast Stain (AFS) in 59% of cases, and the rest of cases were confirmed using polymerase chain reaction (PCR) tests. There are two used treatment regimens, with 12.4% relapse. The gastrointestinal tract (GIT) disturbances were the most related side effects. The resistance has been detected to pyrazinamide in six cases, rifampicin in three cases, and isoniazid, streptomycin and kanamycin were detected in one case. Conclusion: The most predominant Bone-TB cases were spine-TB that were mainly disseminated from the lungs. AFS failed to detect tubercle bacilli in 40% of cases. There is no statistical significance in relapse between the used two regimens. The death was predominant among skull-TB cases.

Abstract
Long term multiple systemic antibiotics form the cornerstone in the treatment of bone and joint tuberculosis, often combined with local surgical eradication. Implanted carriers for local drug delivery have recently been introduced to overcome some of the limitations associated with conventional treatment strategies. In this study, we used a calcium sulphate hemihydrate (CSH)/nanohydroxyapatite (nHAP) based nanocement (NC) biomaterial as a void filler as well as a local delivery carrier of two standard of care tuberculosis drugs, Rifampicin (RFP) and Isoniazid (INH). We observed that the antibiotics showed different release patterns where INH showed a burst release of 67% and 100% release alone and in combination within one week, respectively whereas RFP showed sustained release of 42% and 49% release alone and in combination over a period of 12 weeks, respectively indicating different possible interactions of antibiotics with nHAP. The interactions were studied using computational methodology, which showed that the binding energy of nHAP with RFP was 148 kcal/mol and INH was 11 kcal/mol, thus varying substantially resulting in RFP being retained in the nHAP matrix. Our findings suggest that a biphasic ceramic based drug delivery system could be a promising treatment alternative to bone and joint TB.

Abstract
The alarming global increase in drug-resistant strains plagues the global fight to end tuberculosis (TB), especially in developing countries. The often reported poor treatment outcomes, sequelae, and lack of best practice guidelines in drug-resistant spinal TB poses a significant challenge in its efficient management. While multi-drug chemotherapy is still the primary modality of treatment, surgical intervention is essential in specific scenarios. With limited data on management and outcomes in drug-resistant spinal TB, there is no consensus on the appropriate therapy regarding the number and duration of drugs and therapeutic endpoints of this conundrum. In this light of limited evidence, we have performed a systematic computerized search using the Cochrane Database of Systematic Reviews, Scopus, Embase, Web of Science, and PubMed databases and studies published over the past 30 years on drug-resistance in spinal TB have been analyzed. This systematic review aims to review the current epidemiology, clinical features, updates in clinical diagnostics and chemotherapy, surgical management, and outcomes in drug-resistant spinal TB. We also consolidate potential areas of action and emphasize the need for research and large scale trials in the management of drug-resistant spinal TB.

Abstract
PURPOSE Mycobacterium tuberculosis is a serious public health problem affecting hundreds of millions of elderly people worldwide, which is difficult to be treated by traditional methods because of the peculiarity of skeletal system and liver damage caused by high-dose administration. In this research, a porous drug release system has been attempted to encapsulate rifampicin (RIF) into poly (ε-caprolactone) (PCL) microspheres to improve the efficacy and benefit of anti-tuberculosis drug in skeletal system. MATERIALS AND METHODS The microspheres prepared by two different methods, oil-in-oil (o/o) emulsion solvent evaporation method and oil-in-water (o/w) method, were characterized in terms of morphology, size, encapsulation efficiency, drug distribution, degradation, and crystallinity. RESULTS The microspheres exhibited a porous structure with evenly drug distribution prepared by o/o emulsion solvent evaporation method, and their diameter ranged from 50.54 to 57.34 μm. The encapsulation efficiency was up to 61.86% when drug-loading content was only 1.51%, and showed a little decrease with the drug-loading content increasing. In vitro release studies revealed that the drug release from porous microspheres was controlled by non-Fickian diffusion, and almost 80% of the RIF were completely released after 10 days. The results of RIF-loaded microspheres on the antibacterial activity against Staphylococcus aureus proved that the porous microspheres had strong antibacterial ability. In addition, the polymer crystallinity had prominent influence on the degradation rate of microspheres regardless of the morphology. CONCLUSION It was an efficient way to entrap slightly water-soluble drug like RIF into PCL by o/o emulsion solvent evaporation method with uniform drug distribution. The RIF-loaded porous PCL microspheres showed the combination of good antimicrobial properties and excellent cytocompatibility, and it could generate gentle environment by PCL slow degradation.

Abstract
Osteoarticular tuberculosis (OATB) is a rare form of tuberculosis (TB) whose incidence rose significantly nowadays especially in the underdeveloped countries. The main risk factors predisposing to this new challenge for the medical system are the Human Immunodeficiency Virus (HIV) epidemic, the migration from TB endemic areas and the development of drug and multidrug-resistant strains of Mycobacterium tuberculosis (Mt). The disease affects both genders and any age group although the distribution depending on gender is controversial and that depending on age has a bimodal pattern. In most cases the initial focus is elsewhere in the organism and the most frequent pathway of dissemination is lympho-haematogenous. The clinical picture includes local symptoms as pain, tenderness and limitation of motion, with some particularities depending on the segment of the osteoarticular system involved, sometimes accompanying systemic symptoms specific for TB and other specific clinical signs as cold abscesses and sinuses. The radiographic features are not specific, CT demonstrates abnormalities earlier than plain radiography and MRI is superior to plain radiographs in showing the extent of extraskeletal involvement. Both CT and MRI can be used in patient follow-up to evaluate responses to therapy. TBhas been reported in all bones of the body, the various sites including the spine (most often involved) and extraspinal sites (arthritis, osteomyelitis and tenosynovitis and bursitis). Two basic types of disease patterns could be present: the granular type (most often in adults) and the caseous exudative type (most often in children) one of which being predominant. The algorithm of diagnosis includes several steps of which detection of Mt is the gold standard. The actual treatment is primarily medical, consisting of antituberculosis chemotherapy (ATT), surgical interventions being warranted only for selected cases. It is essential that clinicians know and refresh their knowledge about manifestations of OATB.

Abstract
Tuberculosis (TB) arthritis accounts for approximately 1%-3% of all cases of TB and for approximately 10%-11% of extra pulmonary cases. Isolated acromioclavicular joint TB has been reported rarely with varied presentations as case series of one to three cases none of them being large studies. In our case, patient presented with pain in left shoulder since one month. Patient was investigated and was diagnosed to have acromioclavicular joint TB on basis of positive Acid Fast Bacilli (AFB) stain and cytology. Patient recovered well with antitubercular therapy. Thus, it is important to send Ziehl-Neelsen (ZN) stain in all cases in an endemic country like India.

Abstract
Most antibiotics were discovered by screening soil actinomycetes, but the efficiency of the discovery platform collapsed in the 1960s. By now, more than 3000 antibiotics have been described and most of the current discovery effort is focused on the rediscovery of known compounds, making the approach impractical. The last marketed broad-spectrum antibiotics discovered were daptomycin, linezolid, and fidaxomicin. The current state of the art in the development of new anti-infectives is a non-existent pipeline in the absence of a discovery platform. This is particularly troubling given the emergence of pan-resistant pathogens. The current practice in dealing with the problem of the background of known compounds is to use chemical dereplication of extracts to assess the relative novelty of a compound it contains. Dereplication typically requires scale-up, extraction, and often fractionation before an accurate mass and structure can be produced by MS analysis in combination with 2D NMR. Here, we describe a transcriptome analysis approach using RNA sequencing (RNASeq) to identify promising novel antimicrobial compounds from microbial extracts. Our pipeline permits identification of antimicrobial compounds that produce distinct transcription profiles using unfractionated cell extracts. This efficient pipeline will eliminate the requirement for purification and structure determination of compounds from extracts and will facilitate high-throughput screen of cell extracts for identification of novel compounds.

Abstract
While tuberculous vertebral osteomyelitis is an ancient scourge, multi-drug resistant-tuberculosis (MDR-TB) is a modern major public health concern. The objective of this study was to review and summarize the data available on MDR-TB spondylitis. An extensive search of the PubMed database was conducted for articles in English relevant to MDR-TB spondylitis by December 2015. Tuberculous spondylitis accounts for 0.5-1% of all TB cases, and it is estimated that there are probably 5000 MDR-TB spondylitis cases each year worldwide. The diagnosis of MDR-TB spondylitis requires a high index of suspicion based on epidemiologic, clinical, and radiologic features. Cultures and susceptibility testing remain the gold standard for the diagnosis of MDR-TB, but this can take several weeks to obtain. Medical treatment is the mainstay of therapy, and ideally, it should be based on drug susceptibility testing. If empiric treatment is necessary, it should be based on drug exposure history, contact history, epidemiology, and local drug resistance data, if available. The total duration of treatment should not be <18-24 months. Clinical, radiographic, and if possible, bacteriologic improvement should be used to assess the treatment success. Surgery should be reserved for neurologic deterioration, significant kyphosis, spinal instability, severe pain, and failure of medical management.

Abstract
The antibiotic compound, rifampicin (RFP), was loaded into porous reinforced β-tricalcium phosphate (β-TCP) scaffolds using three different solution adsorption methods. This resulted in drug delivery systems (DDS) generated by vacuum adsorption (VA), dynamic adsorption (DA), and static adsorption (SA). In vitro examination of the drug loading and release profiles of the DDS indicated that the unit mass of RFP loaded into the scaffold by the VA method (0.44 mg/g) was higher than that achieved by SA (0.42 mg/g) or DA (0.38 mg/g) (P < 0.05). The mechanical strength had no significant change after RFP-loading (P > 0.05). Moreover, there were no significant differences among the mechanical strength of three β-TCP DDS generated by loading RFP using SA, DA, and VA (P > 0.05). In vitro release testing showed an initial burst release of RFP from the three different DDS within the first 3 h and in the first 51 h, the cumulative release of RFP from VA-DDS, DA-DDS, and SA-DDS had reached 56.2, 83.6, and 88.6 %, respectively. Complete RFP release had occurred from VA-DDS, DA-DDS, and SA-DDS after 23, 17, and 15 days, respectively. As the VA-DDS method showed improved RFP loading and a more sustained drug release, this method is recommended for solution adsorption drug loading into porous β-TCP scaffolds to form a DDS.

Abstract
The study was to develop and evaluate the rifapentine-loaded poly(lactic acid-co-glycolic acid) (PLGA) microspheres (RPMs) for the treatment of osteoarticular tuberculosis to avoid critical side effects caused by oral regimens of antibiotics or intravenous antibiotics. The RPMs were spherical with rough surfaces, and elevated amounts of rifapentine in the formulation markedly increased the particle size and drug loading, while decreased the size distribution and entrapment efficiency. The highest drug loading and encapsulation efficiency of RPMs were 23.93%±3.93% and 88.49%±8.49%, respectively. After the initial rapid drug release, the release rate gradually decreased, and approximately 80% of the encapsulated rifapentine was released after 30 days of incubation. Moreover, RPMs could effectively inhibit the growth of Staphylococcus aureus. With increasing rifapentine content, the inhibition zones were continuously enlarged while the minimal inhibitory concentration values decreased. These results suggested that RPMs were bioactive and controlled release delivery systems for the treatment of osteoarticular tuberculosis.
