Lymphadenitis is the most common clinical feature in nontuberculous mycobacterium infection in immunocompetent children. We present two case reports of M. lentiflavum lymphadenitis diagnosed in a tertiary hospital in the last 10 years. Routine tests were performed after persistent adenopathy, and a sample for culture was obtained, being positive for this microorganism. Both patients received oral antibiotics during several weeks. Case 1 needed complete excision after five months of treatment, whilst Case 2 was cured by medical therapy. M. lentiflavum is considered, among the newly described nontuberculous mycobacterial species, an emergent pathogen in our environment. It has its own microbiological and clinical characteristics, different from the rest of nontuberculous mycobacteria. Case reports are limited in the literature since the infection was described for the first time in 1997.
- Clinical characteristics of pulmonary Mycobacterium scrofulaceum disease in 2001-2011: A case series and literature review. [Journal Article]
- J Infect Chemother 2016; 22(9):611-6JI
- CONCLUSIONS: We conclude that in the recent histories of our institutions, pulmonary M. scrofulaceum disease has mainly occurred in patients with chronic pulmonary diseases. We further conclude that combination therapies that include clarithromycin might yield better patient outcomes.

Neutralizing anti-interferon-γ autoantibody (nAIGA)-associated immunodeficiency is an emerging medical issue worldwide. In the present study, we describe and discuss the clinical features and outcomes of patients with nAIGAs and disseminated infections by nontuberculous mycobacteria (dNTM).We thoroughly reviewed the medical records of all patients. Microorganisms and nAIGAs were identified using previously described methods with modifications. All data were calculated and analyzed using SPSS software.Among 46 adult patients with dNTM infections, we identified 45 cases (97.8%) with nAIGAs. The average patient age was 58.6 years, and there was no sex predominance. Cervical lymphadenitis (81.8%) was the most common clinical manifestation. Endocrine disorder was the leading comorbidity (7 cases). Malignancies were found in 4 patients, and all of the malignancies originated from the T-cell/macrophage lineage. More than half of the identifiable isolates were slow-growing NTMs. Twenty-eight (62.2%) and 18 (40.0%) patients had a history of zoster and salmonellosis, respectively. A high proportion of patients with recurrent episodes of NTM infection or a history of zoster and dNTM infection had initial nAIGA titers ≥10 dilution (P < 0.05). Twenty-seven patients (60.0%) required long-term antimycobacterial therapy and had at least 1 episode of recurrent NTM disease. No mortality was related to dNTM infection.In Taiwan, nAIGAs are a recently recognized mechanism of dNTM infection. Long term of antibiotic treatment and adherence to medical advice are necessary to improve the clinical outcome of patients with nAIGAs.
- Nontuberculous Mycobacterial Disease in Children - Epidemiology, Diagnosis & Management at a Tertiary Center. [Journal Article]
- PLoS One 2016; 11(1):e0147513Plos
- CONCLUSIONS: There was seasonal variation in the incidence of NTM disease, analogous to recently published observations in tuberculosis, which have been linked to seasonal variation in vitamin D. Our finding that anti-mycobacterial combination therapy was associated with a reduced risk of recurrences in patients with NTM lymphadenitis or SSTI requires further confirmation in prospective trials.

Non-tuberculous mycobacterial adenitis is getting more common in our environment. Epidemiologic studies and clinical trials published nowadays are limited. We present a 2-years-old boy diagnosed of Mycobacterium intracellulare adenitis and severe neutropenia as side effect of combined treatment with oral azythromycin and rifabutin, which recovers after suspending the second one. Liver metabolism of macrolide seems to increase other drugs toxicity, in this case, rifabutin. The patient eventually needed surgery due to persistence of the adenitis despite treatment with antibiotics.
- Long-term Follow-up of Observation-Only Management of Nontuberculous Mycobacterial Lymphadenitis. [Journal Article]

A total of 21 children with clinically and microbiologically proven craniofacial nontuberculous mycobacterial lymphadenitis managed by observation only at a tertiary medical center in 1993-2005 were evaluated for scar parameters at least 2 years after diagnosis. Parents completed a satisfaction questionnaire. Median follow-up time from presentation was 6.8 years (range = 2.3-16.9 years). In all, 18 patients showed scar formation, for a total of 26 scars; 21 scars (81%) had a maximal length of ≤3 cm. Vascularity was normal in 20 scars (77%), and pigmentation was normal in 18 (69%); 21 scars (81%) had a normal to only mildly uneven surface. Although 8 parents (44%) reported that the presence of the scar disturbed them, all responders but one (94%) expressed overall contentment of observation only as a conceivable management alternative. In conclusion, an observation-only approach to craniofacial nontuberculous mycobacterial lymphadenitis is associated with an acceptable outcome and may be an alternative to patients who wish to avoid surgery.
- Mycobacterium tuberculosis causing tuberculous lymphadenitis in Maputo, Mozambique. [Journal Article]
- BMC Microbiol 2015; 15:268BM
- CONCLUSIONS: M. tuberculosis was the main etiological agent of TBLN in Maputo. M. tuberculosis genotypes were similar to the ones causing pulmonary TB, suggesting that in Maputo, cases of TBLN arise from the same source as pulmonary TB, rather than from an external zoonotic source. Further research is needed on other forms of extrapulmonary TB and in rural areas where there is high prevalence of bovine TB in cattle, to evaluate the risk of transmission of M. bovis from cattle to humans.

Childhood cervical lymphadenitis caused by nontuberculous mycobacteria is a diagnostic challenge for the clinician. We present a new promising diagnostic method for childhood nontuberculous mycobacterial lymphadenitis. The modified T-SPOT.TB test with purified protein derivative as an additional antigen is noninvasive with estimated sensitivity and specificity of 1.00 and 0.81, respectively.

Nontuberculous mycobacteria (NTM) infection is a challenging diagnosis for clinicians in solid organ transplantation. Immune reconstitution inflammatory syndrome (IRIS) is so far unreported in this context. We report here the case of a renal transplant recipient who developed Mycobacterium kansasii-associated lymphadenitis complicated by IRIS while undergoing reduction of his immunosuppressive therapy. For IRIS, the patient required low-dose steroids and an increase in global immunosuppression, in association with NTM antibiotherapy.
