Abstract
BACKGROUND Non-tuberculous mycobacteria (NTM) are generally free-living organism, widely distributed in the environment, with sporadic potential to infect. In recent years, there has been a significant increase in the global incidence of NTM-related disease, spanning across all continents and an increased mortality after the diagnosis has been reported. The decisions on whether to treat or not and which drugs to use are complex and require a multidisciplinary approach as well as patients' involvement in the decision process. METHODS AND RESULTS This review aims at describing the drugs used for treating NTM-associated diseases emphasizing the efficacy, tolerability, optimization strategies as well as possible drugs that might be used in case of intolerance or resistance. We also reviewed data on newer compounds highlighting the lack of randomised clinical trials for many drugs but also encouraging preliminary data for others. We also focused on non-pharmacological interventions that need to be adopted during care of individuals with NTM-associated diseases CONCLUSIONS: Despite insufficient efficacy and poor tolerability this review emphasizes the improvement in patients' care and the needs for future studies in the field of anti-NTM treatments.

Abstract
Most peritoneal dialysis (PD)-associated infections caused by Mycobacterium abscessus (M. abscessus) require a transfer from PD to hemodialysis (HD). Here, we report a pediatric case of exit-site and tunnel infections caused by M. abscessus, for whom PD was continued with catheter replacement, debridement of the infected site, and the administration of multiple antibacterial agents. A 10-year-old boy with end-stage kidney disease secondary to juvenile nephronophthisis with NPHP1 deletion, for whom PD was initiated at the age of 9 years, was admitted to the hospital with complaints of fever, pus at the exit-site of the PD catheter, and poor PD drainage. The dialysis effluent culture results were negative; however, M. abscessus was detected in the pus at the exit-site of the PD catheter. The management of HD was expected to be challenging owing to the presence of developmental disorders. Therefore, PD was continued with the simultaneous removal of the PD catheter, reinsertion of a new catheter at a new site, and debridement of the infected site. Multiple antibacterial therapies were administered for 2 months, and the patient was eventually discharged without switching to HD. To the best of our knowledge, this is the first pediatric case of a PD-associated infection caused by M. abscessus, for whom PD was continued without switching to HD. This treatment strategy is not generally recommended but may be an option for patients without peritonitis who have difficulty switching to HD.

Abstract
Sclerosing encapsulating peritonitis (SEP) is a rare condition characterised by a fibrotic peritoneal membrane encasing loops of bowel often resulting in obstruction. We present a case of SEP complicated by non-resolving small bowel obstruction in the context of prior malignancies and surgical complications. A literature review on SEP was performed to outline potential aetiologies, diagnostic investigations and treatment strategies that may be considered in the management of this disease.

Abstract
Non-tuberculous mycobacteria (NTM) are opportunistic pathogens that can infect all body tissues and organs. In particular, the lungs are the most commonly involved organ, with NTM pulmonary diseases causing serious health issues in patients with underlying lung disease. Moreover, NTM infections have been steadily increasing worldwide in recent years. NTM are also naturally resistant to many antibiotics, specifically anti-tuberculosis (anti-TB) drugs. The lack of drugs targeting NTM infections and the increasing drug resistance of NTM have further made treating these mycobacterial diseases extremely difficult. The currently recommended NTM treatments rely on the extended indications of existing drugs, which underlines the difficulties of new antibiotic discovery against NTM. Another challenge is determining which drug combinations are most effective against NTM infection. To a certain extent, anti-NTM drug development depends on using already available antibiotics and compounds. Here, we aimed to review new antibiotics or compounds with good antibacterial activity against NTM, focusing on their mechanisms of action, in vitro and in vivo antibacterial activities.

JOURNAL OF THE ASSOCIATION OF MEDICAL MICROBIOLOGY AND INFECTIOUS DISEASE CANADA = JOURNAL OFFICIEL DE L'ASSOCIATION POUR LA MICROBIOLOGIE MEDICALE ET L'INFECTIOLOGIE CANADA 2022; 7:125-130.

Abstract
BACKGROUND Non-tuberculous mycobacteria (NTM) are an uncommon but serious cause of peritoneal dialysis (PD)-related infections. NTM peritonitis typically necessitates PD catheter removal, PD withdrawal, and aggressive, prolonged antimicrobial treatment. Few reported cases of NTM peritonitis in the pediatric population exist. METHODS We describe a case of a 9-year-old boy on PD after kidney allograft failure who developed Mycobacterium fortuitum peritonitis, and we summarize the available literature on M. fortuitum peritonitis in pediatric patients receiving PD. RESULTS AND CONCLUSION Therapeutic options were limited by adverse medication effects and risk of drug-drug interactions in a patient with complex mental health comorbidities. Clofazimine presented an acceptable oral treatment option for long-term therapy in combination with ciprofloxacin and was well tolerated by this patient. Prompt PD catheter removal followed by 6 months of dual antimicrobial therapy resulted in a full recovery and successful re-transplantation with no infection relapse.

Abstract
A preschool child with refractory peritoneal dialysis-related exit-site infection (ESI)/peritonitis caused by Mycobacterium abscessus (M. abscessus) received multidrug antibacterial therapy for 6 months and then successfully underwent living-donor kidney transplantation. The patient was a 2.7-year-old boy and the primary disease was bilateral hypo/dysplastic kidneys. Peritoneal dialysis (PD) was initiated at the age of 4 months. Purulent drainage from the PD catheter exit site was observed, and pus and PD effluent cultures were negative. Since living kidney transplantation was scheduled for 2 months later, the PD catheter was replaced. Due to dialysate leakage from the exit site, the new PD catheter was removed and hemodialysis was initiated. M. abscessus subsequently grew from the PD effluent and abscesses that formed at the exit site continued to present bacteria even after catheter removal; therefore, additional debridement was performed. He received combination treatment with antibiotics, amikacin, clarithromycin, imipenem/cilastatin sodium, and tigecycline, for 6 months. After a 4-month observation period without antibiotics, the patient underwent living-donor kidney transplantation. The post-transplantation course was uneventful without the recurrence of infection for 2 years. Although PD-related ESI/peritonitis caused by M. abscessus was intractable, PD catheter removal, multiple debridement, and 6-month antibiotic combination therapy led to improvements. Follow-up observations for 4 months after the cessation of antibacterial treatment confirmed no recurrence of M. abscessus infection, which allowed kidney transplantation. The establishment of an appropriate treatment strategy and observation period for M. abscessus infection ahead of kidney transplantation requires further case accumulation.

Abstract
BACKGROUND Decline in skills and knowledge among patients and/or caregivers contributes to peritoneal-dialysis (PD)-related peritonitis. Re-training is important, but no guidelines exist. We describe the implementation of a structured re-training program to decrease peritonitis rates. METHODS This is a prospective quality improvement study involving pediatric patients on long-term home automated PD at National University Hospital, Singapore, between 2012 and 2018. With increasing peritonitis rates, systematic root cause analysis was performed, and based on the contributory factors identified, a structured re-training program was implemented from 2015. This was conducted in 5 cycles, each consisting of 4 modules (hand hygiene, exit site care, peritonitis, and PD troubleshooting). RESULTS Peritonitis rates were analyzed in 2 phases: Phase 1 (2012-2014) when no re-training was performed and Phase 2 (2016-2018) after re-training was instituted. Fifty-nine patients were included. Of these, 45 patients were in Phase 1, 32 in Phase 2, and 18 in both phases. Peritonitis rates decreased from 0.37 ± 0.67 episodes per patient-year in Phase 1 to 0.13 ± 0.32 episodes per patient-year in Phase 2. After adjusting for age at kidney failure onset, PD vintage, years of nursing experience, and the average patient-to-nurse ratio over the study period for each patient, the adjusted peritonitis rates decreased by 0.38 episodes per patient-year (95% CI, 0.09 to 0.67, p = 0.011) from Phase 1 to Phase 2. CONCLUSION Despite an improvement in staffing ratio, peritonitis rates only improved significantly after intensive structured re-training was instituted.

Abstract
Peritoneal dialysis (PD)–associated peritonitis constitutes a major complication associated with the procedure. PD-associated peritonitis caused by nontuberculous mycobacteria, usually as a result of an infection related to the PD catheter, has been reported in adults and is associated with significant complications and poor outcome. The management of PD-associated peritonitis caused by Mycobacterium abscessus is particularly challenging because this species is resistant to many antimicrobials commonly used to treat mycobacterial species. We present here the second reported case of PD-associated peritonitis caused by M. abscessus in children. Our patient was a 9-year-old boy with end-stage renal disease (ESRD) who presented with suspected peritonitis, and his PD fluid cultures eventually grew M. abscessus. The patient received a 3-week course of triple therapy with clarithromycin, amikacin, and meropenem in addition to PD catheter removal. The infection completely resolved even though a susceptibility report at the end of treatment revealed that the isolate was resistant to clarithromycin and had decreased susceptibility to carbapenems. Our observations suggest that PD catheter removal is important in PD-associated peritonitis caused by M. abscessus in children and that more studies are needed to define the optimal length of treatment.
