Myocardial tuberculosis and beyond: A rare form of extra pulmonary TB in a young boy.

Myocardial tuberculosis is an exceptionally rare form of extra-pulmonary TB. Few cases were reported world-wide. Here a young snake charmer who had skin tuberculosis 5 yrs back admitted into National institute of diseases of Chest and hospital (NIDCH), Dhaka with the complaints of cough, palpitation and breathlessness for 2 months. He had right axillary firm matted lymphadenopathy, left sided large pleural effusion, left ventricular and septal hypertrophy with band and mass inside the ventricle (evident on CT scan of heart and echocardiography). His ESR was 95 mm in1st hr, Mantaux test was 15mm, Pleural fluid was exudative lymphocyte predominant with adenosin deaminase (ADA) 68.6 U/L. Fine needle aspirates from right axillary LNs showed Mycobacterium tuberculosis on GeneXpert for MTB/RIF testing and caseous granuloma on cytopathological study. Whole Body F18 FDG PET-CT revealed numerous low FDG avid size significant lymph nodes in right side of neck, mediastinum and right axilla with cardiomegaly with focal FDG avid within the left ventricular cavity likely to be prominent papillary muscle. MRI of heart or Myocardial biopsy for histology was not done due to their cost and invasiveness and also for that there was sufficient evidence of having tuberculosis in lymph node, pleura nas myocardium. This patient was treated with anti tubercular medications (3HRZE2S/5HRE) with prednisolone for six months. After treatment, myocardial lesions, pleural effusion and lymphadenopathy were found resolved. Thus a case of fatal and serious tuberculosis was explored and managed successfully.

Isolated Nodal TBC Reactivation in a Patient with Post-Thrombocythemia Myelofibrosis Treated with Ruxolitinib: Case Report and Review of the Literature.

Ruxolitinib side effects include the most frequent hematological toxicity along with a more recently evidenced immunosuppressive activity, interfering both with the innate and adaptive immunity, and several cases of reactivation of latent infections by opportunistic agents in patients in treatment with ruxolitinib have been published in the last years. Several pathophysiological mechanisms may explain an association between ruxolitinib and opportunistic infections. From what we know, the only case of an isolated lymph node TBC reactivation in a ruxolitinib-treated myelofibrosis (MF) patient was reported by Patil et al. in 2016 [Int J Med Sci Public Health. 2017;6(3):1]. Other 10 cases describing TBC reactivations in MF patients assuming ruxolitinib and successfully treated with 4-drug anti-TBC therapy are available in the literature to date. The case we reported describes an isolated lymph nodal TBC reactivation in a patient with the diagnosis of post-essential thrombocythemia-MF during ruxolitinib treatment after a long course of interferon-a (IFN-α2b) assumed for the previous diagnosis of ET. The case we report teaches that lymphadenopathy with or without constitutional symptoms developing during ruxolitinib therapy should be considered as a possible manifestation of a TBC reactivation in patients with a previous positive TBC-exposure test. In these cases, Ziel-Nielsen testing on urine and sputum has to be performed to rule out infectiousness and eventually isolate the patient. Moreover, previous long-time exposition to IFN-α2b may be related with a higher risk for TBC reactivation in these subset of patients. We encourage reevaluation of the cohorts of patients treated with ruxolitinib in previous and current large prospective studies to study the possible correlation between previous exposition to IFN-α2b and TBC reactivation.

Bacillus Calmette-Guérin Cervical Lymphadenitis in a 6-Year-Old Boy on Infliximab for Inflammatory Bowel Disease.

We encountered a case of Bacillus Calmette-Guérin (BCG) cervical lymphadenitis in a patient undergoing infliximab after 6 years from BCG vaccination. Tumor necrosis factor-α inhibitors may be a risk for reactivation of BCG and serious infection even several years after vaccination.

[Disseminated infection caused by the bacillus Calmette-Guérin vaccine and SARS-CoV-2 coinfection in a patient with IL-12 receptor ß1 subunit deficiency]. / Infección diseminada por vacuna con bacilo de Calmette-Guérin y coinfección por SARS-CoV-2 en paciente con deficiencia de la subunidad ß1 del receptor de IL-12.

BACKGROUND: Inborn errors of immunity manifest with a greater susceptibility to infections, autoimmunity, autoinflammatory diseases, allergies, or malignancies. One of these is the mendelian susceptibility to mycobacterial disease. The most frequent etiology is the complete autosomal recessive deficiency of the ß1 subunit of the interleukin 12 receptor. CASE REPORT: A female patient who, by the age of six months, started with a nodular lesion in the right shoulder and ipsilateral axillary adenitis after the bacillus Calmette-Guérin vaccine was applied. Later, she developed a cutaneous fistula in the anterior thorax, the inframammary region, and chronic recidivant suppurative lymphadenitis. A disseminated infection caused by Mycobacterium bovis was diagnosed, therefore, individualized pharmacological treatment was required due to failure with the primary treatment. The patient was diagnosed with deficiency in the ß1 subunit of the interleukin 12 receptor at age six. During her last hospitalization, she presented fever, cough, and tachypnea, and SARS-CoV-2 was detected by quantitative polymerase chain reaction. The patient has had a favorable evolution. CONCLUSION: In patients with disseminated infections caused by bacillus Calmette-Guérin vaccination or by environmental mycobacteria, there should be suspicion of an inborn error of immunity and the patient should be referred to a third level hospital for an early immunological assessment.

Antecedentes: Los errores innatos de la inmunidad se manifiestan con una mayor susceptibilidad a infecciones, autoinmunidad, enfermedades autoinflamatorias, alergia o malignidad. Uno de estos es la susceptibilidad mendeliana a infecciones micobacterianas. La etiología más frecuente es la deficiencia completa autosómica recesiva de la subunidad ß1 del receptor de interleucina 12. Caso clínico: Paciente que comenzó a los seis meses de edad con una lesión nodular en hombro derecho y adenitis axilar ipsolateral posterior a la vacuna con bacilo de Calmette-Guérin. Posteriormente desarrolló una fistula cutánea en tórax anterior, región inframamaria y linfadenitis supurativa crónica recidivante. Se diagnosticó infección diseminada por Mycobacterium bovis, por lo que requirió tratamiento farmacológico individualizado debido al fracaso con el tratamiento primario. La paciente fue diagnosticada con deficiencia de la subunidad ß1 del receptor de interleucina 12 a los seis años. Durante su última hospitalización presentó fiebre, tos y taquipnea, detectándose SARS-CoV-2 por reacción en cadena de la polimerasa cuantitativa. La paciente evolucionó favorablemente. Conclusión: En los pacientes con infecciones diseminadas por la vacuna con bacilo de Calmette-Guérin o micobacterias ambientales, debe sospecharse un error innato de la inmunidad y derivarlos a tercer nivel de atención para la evaluación inmunológica temprana.

Lymphatic spread in an immunocompetent adult.

Cutaneous tuberculosis with lymphatic spread is rarely described. We report the case of a woman aged 38, immunocompetent, working in a fruit sorting center, who consulted us for ulceration of the left third finger that had persisted for four months, following a prick from a prickly pear. Physical examination revealed a nodular, erythematous, and ulcerative lesion of the left third finger, associated with inflammatory subcutaneous nodules arranged in a line along the ipsilateral upper extremity and an ipsilateral axillary lymph node. Laboratory tests and chest X-ray were normal. Pathological examination revealed granulomatous chronic inflammation without necrosis. PCR detected DNA from Mycobacterium tuberculosis. No extracutaneous tuberculosis locations were detected. A tuberculous chancre by direct inoculation was therefore diagnosed. The patient received quadruple therapy (rifampicin + isoniazid + pyrazinamide + ethambutol) for 2 months, followed by a combination therapy based on isoniazid and rifampicin for 6 months. Marked regression of the cutaneous lesions occurred after 1 month of first-line therapy. A tuberculous chancre is a rare form of cutaneous tuberculosis, with possible lymphatic spread, in immunocompromised patients but also in immunocompetent children and young adults.

Bacteriologically Determined De Novo Tuberculosis during Tumor Necrosis Factor-α Inhibitor Therapy.

A 58-year-old man with Crohn's disease received adalimumab for 13 months after screening results for tuberculosis were found to be negative. He was diagnosed with de novo mediastinal lymph-node tuberculosis, which was proved to be bacteriologically identical to that of an individual with smear positive lung tuberculosis by a variable number of tandem repeat analyses. After initiating anti-tuberculosis therapy, the patient developed immune reconstitution syndrome, which was improved by the re-administration of adalimumab. Even in countries with an intermediate tuberculosis burden, including Japan, we need to be alert for de novo tuberculosis as well as its reactivation during tumor necrosis factor-α inhibitor therapy.

A case report of granulomatous polyangiitis complicated by tuberculous lymphadenitis.

RATIONAL: Granulomatous polyangiitis (GPA) is a type of vasculitis involving medium and small arteries, typically affecting the upper and lower respiratory tract with coexisting glomerulonephritis. GPA is also characterized by necrotizing granulomatous inflammation and the presence of antineutrophil cytoplasm antibodies (ANCA). So far, various infections have lead to elevation of titers of serum ANCA, making it difficult to diagnose. PATIENT CONCERNS: We report a 50-year-old woman who was diagnosed as tuberculous lymphadenitis. During the treatment by anti-tuberculosis (TB) drugs, rapidly progressive renal failure and pleurisy had appeared with elevated titer of PR3-ANCA. Renal biopsy revealed crescentic glomerulonephritis. DIAGNOSIS: Renal biopsy revealed crescentic glomerulonephritis and diagnosis of GPA was made. INTERVENTIONS: Steroid therapy had been started with continuation of anti-TB drugs. OUTCOMES: Renal dysfunction had gradually recovered and pleurisy had disappeared with decreasing titer of PR3-ANCA. LESSONS: This is the first report of GPA complicated by TB infection. When we encounter a case with rapidly progressive renal failure during the TB infection, complication of GPA should be suspected as 1 of the different diagnosis.

Diagnosis and Management of Children With Mycobacterium abscessus Infections in the Head and Neck.

PURPOSE: Controversy exists regarding the most appropriate treatment strategy for children with nontuberculous mycobacterial (NTM) cervical lymphadenitis. Mycobacterium abscessus (MAB) is an uncommon cause of NTM cervical lymphadenitis. The purpose of the present study was to evaluate diagnosis, management, and treatment outcomes in children with MAB-associated cervical lymphadenitis resulting from a pulpotomy. MATERIALS AND METHODS: This was a retrospective chart review of children with NTM lymphadenitis of the head and neck caused by MAB treated at Children's Healthcare of Atlanta hospitals (Atlanta, GA). The predictor variables were patient demographics, dental history, clinical presentation, imaging characteristics, laboratory findings, histopathologic examination, treatment, and complications. The outcome variable was disease resolution or persistence. RESULTS: Twenty-two patients (mean age, 6.5 yr) met the inclusion criteria. All patients had pulpotomy at 1 dental practice. The mean time from dental procedure to symptom onset was 43.1 days (range, 3 to 180 days). Children presented with cervical or submandibular swelling, facial swelling, gingival erythema, and skin erythema. Radiographic findings were submandibular or cervical lymphadenitis, maxillary or mandibular osteolysis, subcutaneous abscess, and pulmonary nodules. All children had confirmed or probable MAB infection diagnosed on the pathologic specimen. There were 2 distinct patient presentations that guided surgical management: isolated noninflammatory cervical lymphadenitis, which was partly or completely excised (n = 11), and adjacent extension or disseminated infection requiring subtotal lymph node excision, bone debridement, and postoperative antibiotics (n = 11). Most children required multiple surgical interventions to remove infected tissues. All achieved clinical resolution. CONCLUSION: In this cohort, treatment of NTM lymphadenitis caused by MAB depended on extent of disease and virulence of bacteria. When complete surgical excision was possible, disease resolution was achieved. However, in cases with adjacent extension or dissemination infection, postoperative antibiotics were necessary.

Mediastinal ganglionar tuberculosis postcardiac transplantation.

The diagnosis and treatment of tuberculosis (TB) in transplanted receivers presents several challenges. TB is an opportunistic infection with high morbidity and mortality in solid organs of transplanted patients, therefore, the diagnosis difficulties. A case of a 30-year-old male, heart transplanted patient, who after being submitted to mediastinoscopy, obtained a result of lymph node TB.

BCG-SSI(®) vaccine-associated lymphadenitis: Incidence and management.

BACKGROUND AND OBJECTIVE: There is a high incidence of childhood tuberculosis in Latvia, including children aged less than 1 year, while BCG-associated lymphadenitis is one of the most frequent adverse events requiring surgical treatment. The aim of this study was to analyze the incidence of purulent BCG adenitis through-out the population of Latvia after the introduction of BCG-SSI(®) vaccine and to evaluate the treatment results. MATERIAL AND METHODS: The study included 194 patients. All patients had received the BCG-SSI(®) vaccine during the first week of life routinely or at a later time according to the indications. The indications for surgical treatment were lymph node destruction also affecting the skin. All patients in this study received surgical treatment - the affected lymph node extirpation. RESULTS: The mean age of the patients was 5.12±0.96 months. A total of 172 patients had purulent axillar lymphadenitis, 14 had purulent supraclavicular lymphadenitis, 8 patients had lymphadenitis at both localizations. During the whole study period the incidence of BCG adenitis varied from 0.02% to 0.36%, while the mean rate was 0.11%±0.08% from 184,068 vaccinated children during the study period. We observed an increasing trend in the incidence of BCG lymphadenitis during the study period. The primary and complete healing rate at the end of period was 99.5% (n=193) following an affected lymph node extirpation. The mean hospitalization time after the operation was 3.71±0.18 days. CONCLUSIONS: The incidence of BCG-SSI(®) vaccine associated purulent lymphadenitis varied widely with an increasing trend, followed by the return to the product characteristic limits. Indications for the surgical treatment should not be changed. Extirpation of the purulent BCG adenitis is a safe treatment method and leads to the primary wound healing in the majority of cases.

Lymph node tuberculosis after melanoma treatment - sometimes the patient is lucky.

Tuberculosis (TB) is considered a pulmonary disease that can however disseminate to other organs through hematogenous dissemination following primary TB infection. Evolution of the disease can either be precocious, before healing of the primary infection, or late after primary infection, due to reactivation of initial lesions usually because of simultaneous immunosuppressive factors such as diabetes, renal disease, hepatic disease or different type of immunosuppressing treatments. Rare cases when tuberculosis and cancer are diagnosed at the same time create diagnostic difficulties and therapeutic challenges. We present the case of an asymptomatic 52-year-old female that was diagnosed "by chance, at the right moment" with a form of skin melanoma on the right forearm, for which she received a rather well tolerated cytostatic treatment. At the end of this treatment, she was also investigated for a breast mass that proved to be benign; however, enlarged lymph nodes were discovered in the right armpit were discovered upon further investigation. One of the lymph nodes was surgically removed, as first suspicion was of a metastasis from the skin melanoma. However, it was lymph node tuberculosis therefore anti-tuberculosis treatment was initiated. The patient tolerated the treatment with minor side effects. On few occasions, a patient can be diagnosed with incipient stages of skin melanoma and even more rarely the same patient is diagnosed and treated prematurely for lymph node tuberculosis. Sometimes, a successful outcome needs an organized and well-educated patient and a little luck.

Mycobacterial cervicofacial lymphadenitis in human immunodeficiency virus-infected individuals after antiretroviral therapy initiation.

OBJECTIVES/HYPOTHESIS: Mycobacterial infections are the leading cause of morbidity and mortality among human immunodeficiency virus (HIV)-infected individuals worldwide. Cervical lymph nodes are the most frequently affected extrapulmonary sites. Despite the substantial reduction in complications of HIV-tuberculosis coinfection, a proportion of individuals develop immune reconstitution inflammatory syndrome (IRIS), a term used for a clinical deterioration following initiation of antiretroviral therapy (ART). The objective of this study was to describe mycobacterial-associated IRIS in cervical lymph nodes of HIV-infected individuals receiving ART. STUDY DESIGN: Retrospective cohort study, set in a tertiary referral center in Mexico City. METHODS: We included ART-naive subjects who had at least one follow-up ear, nose, and throat examination, and were diagnosed with lymph node mycobacterial infection before or during the first 3 months of ART initiation. Mycobacterial-associated IRIS in cervical lymph nodes was determined retrospectively through clinical case definition and medical chart review. RESULTS: Thirty-three subjects who initiated ART were diagnosed with cervical lymph node mycobacteriosis; 24 had Mycobacterium tuberculosis infection and nine had nontuberculous disease. CONCLUSIONS: M. tuberculosis was the most common pathogen isolated from cervical lymph nodes. The only factor associated with IRIS was infection with a nontuberculous mycobacteria. The unexpectedly high incidence of mycobacterial-associated IRIS underlines the relevance of head and neck examination before ART initiation. LEVEL OF EVIDENCE: 4.

Evaluation of the efficiency of nested q-PCR in the detection of Mycobacterium tuberculosis complex directly from tuberculosis-suspected lesions in post-mortem macroscopic inspections of bovine carcasses slaughtered in the state of Mato Grosso, Brazil.

Bovine tuberculosis (BTB) is a zoonotic disease caused by Mycobacterium bovis, a member of the Mycobacterium tuberculosis complex (MTC). The quick and specific detection of this species is of extreme importance, since BTB may cause economic impacts, in addition to presenting imminent risks to human health. In the present study a nested real-time PCR test (nested q-PCR) was used in post-mortem evaluations to assess cattle carcasses with BTB-suspected lesions. A total of 41,193 cattle slaughtered in slaughterhouses located in the state of Mato Grosso, were examined. Of the examined animals, 198 (0.48%) showed BTB-suspected lesions. M. bovis was isolated in 1.5% (3/198) of the samples. Multiplex-PCR detected MTC in 7% (14/198) of the samples. The nested q-PCR test detected MTC in 28% (56/198) of the BTB-suspected lesions, demonstrating higher efficiency when compared to the multiplex-PCR and conventional microbiology. Nested q-PCR can therefore be used as a complementary test in the national program for control and eradication of bovine tuberculosis.

A late presentation of isolated lymph node tuberculosis postintravesical BCG therapy for superficial bladder cancer: a novel case.

Intravesical BCG immunotherapy is commonly used in the treatment of superficial bladder cancer. We recount the case of an 82-year-old British man who completed a course of BCG immunotherapy in 2011 for superficial bladder cancer, and presented in January 2013 with a loss of appetite, loss of weight and severe back pain. CT scanning, followed by MRI displayed a 5.7 cm × 5 cm conglomerated necrotic, haemorrhagic mass of lymph nodes in the para-aortic region. A CT-guided biopsy revealed granulomatous inflammation, focal fibrosis and acid-fast bacilli consistent with Mycobacterium tuberculosis (TB). The patient was treated with combination antituberculous medication, and is recovering. To our knowledge, this is the only reported case of lymph node TB secondary to intravesical BCG immunotherapy. We suggest that in patients treated with postintravesical BCG with enlarged lymph nodes, a diagnosis of secondary TB should be considered.

[A clinical study on 8 cases of sarcoidosis with a cervical mass as a symptom].

Sarcoidosis is a multiorgan granulomatous disease of unknown origin, which frequently involves the lung and the eyes. It is rare that sarcoidosis causes cervical lymphadenopathy and a chronic continuous salivary gland swelling. In the present study, we examined how to diagnose sarcoidosis in patients complaining of a cervical mass and its clinical presentation according to 8 cases which we experienced. We undertook biopsy of the cervical lymph nodes in 7 cases, and biopsy of the parotid gland in 1 case. In cases non-caseating epithelioid cell granuloma was proved, diagnosed as sarcoidosis histopathlogically. In 6 patients, the sarcoidal lesion was in other organs, whereas in 2 patients the sarcoidal lesion was confined in the head and neck. Bilateral hilar lymphadenopathy and an elevated level of angiotensin-converting enzyme which are typical in sarcoidosis were confirmed in only one of our patients. Therefore, the diagnostic value of these tests is low for the diagnosis of sarcoidosis in the patients whose chief complaint is a cervical mass. Because 4 out of 7 cases were positive for the tuberculin test, it is imperative to distinguish between sarcoidosis and cervical tuberculous lymphadenitis by combining the culture of acid-bacilli and TB-PCR with histopathological evaluation of the biopsy specimen. We experienced one patient in whom the sarcoidal lesion developed in the skin and the eyes 20 years after the onset of cervical lymphadenopathy. It is important to follow the patients carefully, even if we diagnose the disease as sarcoidosis confined in the head and neck.

Tuberculosis lymphadenitis in a well managed case of sarcoidosis.

Differentiation between tuberculosis (TB) and sarcoidoisis is sometimes extremely difficult. Sequential occurrence of sarcoidosis and TB in the same patient is uncommon. We present the case of a young man, with a proven diagnosis of sarcoidosis who later developed TB after completion of treatment for sarcoidosis. A 32-year-old male patient presented with low-grade fever since two months. Physical examination revealed cervical lymphadenopathy. Initial fine needle aspiration cytology (FNAC) of the cervical lymph node was suggestive of granulomatous inflammation; the chest radiograph was normal. Repeat FNAC from the same lymph node was suggestive of reactive lymphoid hyperplasia. The patient was treated with antibiotics and followed-up. He again presented with persistence of fever and lymphadenopathy and blurring of vision. Ophthalmological examination revealed uveitis, possibly due to a granulomatous cause. His repeat Mantoux test again was non-reactive; serum angiotensin converting enzyme (ACE) levels were raised. This time an excision biopsy of the lymph node was done which revealed discrete, non-caseating, reticulin rich granulomatous inflammation suggestive of sarcoidosis. The patient was treated with oral prednisolone and imporved symptomatically. Subsequently, nearly nine months after completion of corticosteroid treatment, he presented with low-grade, intermittent fever and a lymph node enlargement in the right parotid region. FNAC from this lymph node showed caseating granulomatous inflammation and the stain for acid-fast bacilli was positive. He was treated with Category I DOTS under the Revised National Tuberculosis Control Programme and improved significantly. The present case highlights the need for further research into the aetiology of TB and sarcoidosis.
