RESUMO
Fibrocalculous pancreatic diabetes (FCPD) mellitus is a distinct type of diabetes that arises from chronic calcification of the pancreas in young, nonalcoholic individuals, predominantly in tropical regions. The characteristic triad of FCPD includes diabetes, abdominal pain, and steatorrhea. Additional notable features of the disease are its early age of onset, the presence of large intraductal stones, rapid disease progression, and a heightened risk of developing pancreatic cancer. Tuberculosis (TB) is a health concern worldwide and is responsible for a major health burden in developing countries like India. TB involving any organ other than the lungs is diagnosed as extrapulmonary tuberculosis (EPTB). EPTB with musculoskeletal involvement is often a difficult and delayed diagnosis because of unusual clinical presentations.

Extra-pulmonary TB (EPTB) is difficult to diagnose due to paucibacillary nature of disease. Current study evaluated accuracy of Truenat MTB and MTB-Rif Dx (TN), for detection of Mycobacterium tuberculosis and resistance to rifampicin. Samples were collected from 2103 treatment naive adults with presumptive EPTB, and tested by smear microscopy, liquid culture (LC) (MGIT-960) and GeneXpert MTB/RIF (GX) (Microbiological Reference Standards, MRS). TN results were compared to MRS and Composite Reference Standards (CRS, Microbiology, histopathology, radiology, clinical features prompting decision to treat, response to treatment). CRS grouped patients into 551 confirmed, 1096 unconfirmed, and 409 as unlikely TB. TN sensitivity and specificity was 73.7% and 90.4% against GX. Against LC, Overall sensitivity of GX was 67.6%, while that of TN was 62.3%. Highest sensitivity by TN was observed in pus samples (89%) and highest specificity (92%) in CSF samples, similar to GX. TN sensitivity was better in fluid and biopsy samples and slightly inferior for lymph node aspirates compared to GX. TN sensitivity for RIF resistance detection was slightly superior to GX. TN and GX results were further compared to Clinical Reference Standards. TN detected 170 TB patients initiated on treatment missed by GX, while GX detected 113 such patients missed by TN. Of 124 samples with RIF resistance discordance between GX and TN, GX reported 103/124 as sensitive, 3/124 as indeterminate and 18 as resistant (13/18 samples had low/very low DNA load) while TN reported RIF resistance indeterminate in 103/111 low/very low DNA load samples. Due to paucibacillary nature of EPTB samples, culture yield was poor and phenotypic drug susceptibility testing failed to resolve the discordance. The study establishes TN at par with GX and can be utilized for quick and accurate diagnosis of EPTB.

Introducción: La tuberculosis (TB) extrapulmonar es la afectación de cualquier órgano, sin compromiso pulmonar demostrado, como consecuencia de la diseminación hematógena/linfática del bacilo de Koch. Presentación de caso: Paciente en puerperio inmediato cursando cuadro clínico de gonalgia que se estudió con resonancia magnética que mostró lesión endomedular en región distal del fémur izquierdo. Se estudió con tomografía de tórax, abdomen y pelvis que evidenciaron otras lesiones a nivel esplénico, sin compromiso hepático ni pulmonar. Se realizó punción diagnóstica femoral con evidencia de granulomas con necrosis central. Se interpretó tuberculosis extrapulmonar y se inició tratamiento antifímico con mejora sintomática. Discusión: La TB extrapulmonar puede impactar a nivel de pleura, ganglios linfáticos, vías urinarias, sistema osteoarticular, sistema nervioso central y abdomen. En el embarazo, la prevalencia de TB extrapulmonar es baja. Conclusión: La TB femoral y esplénica concomitante en pacientes embarazadas es un hallazgo infrecuente por lo que su análisis resulta de gran importancia. Arribar al diagnóstico requiere un elevado índice de sospecha. El retraso diagnóstico conlleva a un aumento de la morbimortalidad
Introduction: Extrapulmonary tuberculosis (TB) is the involvement of any organ, without demonstrated pulmonary involvement, as a consequence of the hematogenous/lymphatic dissemination of the Koch bacillus. Case presentation: Patient in the immediate postpartum period with clinical symptoms of gonalgia that was studied with magnetic resonance imaging showing intramedullary lesion in the distal region of the left femur. A CT scan of the chest, abdomen and pelvis showed other lesions at the splenic level, without liver or lung involvement. A femoral diagnostic puncture was performed with evidence of granulomas with central necrosis. Extrapulmonary tuberculosis was interpreted and antifimic treatment was started with symptomatic improvement. Discussion: Extrapulmonary TB can impact the pleura, lymph nodes, urinary tract, osteoarticular system, central nervous system and abdomen. During pregnancy, the prevalence of extrapulmonary TB is low. Conclusion: Concomitant femoral and splenic TB in pregnant patients is a rare finding, which is why its analysis is of great importance. Arriving at a diagnosis requires a high index of suspicion. Delayed diagnosis leads to an increase in morbidity and mortalit

Rapid and highly accurate diagnostic tools are critically needed to diagnose Mycobacterium tuberculosis and rifampicin resistance in AFB smear-negative samples. In this study, we evaluated the diagnostic performance of Xpert MTB/RIF Ultra (Ultra) as a rapid test to diagnose tuberculosis in smear-negative cases in Malaysia. A retrospective study of 1960 smear-negative pulmonary and extrapulmonary samples obtained from patients was conducted. Culture was used as the reference standard for the study. The overall sensitivity and specificity of Ultra on the tested samples were 88.7 % and 77.2 %, respectively, while the PPV was 32.3 % and the NPV was 98.2 %. Ultra showed slightly higher sensitivity in pulmonary (89.9 %) compared to extrapulmonary samples (86.1 %). The overall accuracy of Ultra was 78.5 % (kappa=0.37; 95 %CI: 0.32,0.42). Ultra showed good diagnostic accuracy for detecting MTB and rifampicin resistance in various AFB smear-negative samples. Ultra also had excellent capability in rifampicin resistance detection.

As it is an infrequent etiology, the diagnosis of perianal tuberculosis is challenging, especially in the absence of a pulmonary focus. TB should be considered in the differential diagnosis of perianal ulcers, fistulas, abscesses, mainly in non-healing and recurrent anal lesions. Treatment with anti-TB agents can provide complete recovery. Furthermore, these lesions are often diagnosed later after complete histopathological and mycobacterial results, where the benefit of avoiding morbid multiple surgeries by effective anti-TB treatment is lost. We reported a rare case of an immuno-competent patient with perianal TB, which was the first manifestation of the disease. A fit-and-well man in his 20s presented a large perianal abscess. Unexpectedly, his chest X-ray showed a rounded hyper-transparency in the left lung. The abscess was drained. Posterior investigation with culture analysis from pus swabs and sputum revealed the presence of Mycobacterium tuberculosis complex infection. After completing the 6 months of oral administration of anti-TB drugs, the patient was asymptomatic. By highlighting this unusual manifestation, we aim to improve clinicians' awareness of perianal TB, facilitating early recognition and appropriate management. (AU)

SETTING: Tubercular lymphadenitis (TBLA), the most common form of extrapulmonary tuberculosis, is a diagnostic challenge. OBJECTIVE: Truenat MTB Plus (TruPlus) along with Truenat Rif assay (TruRif) was evaluated for detection of TBLA and rifampicin resistance and compared with GeneXpert Ultra (Xpert Ultra). DESIGN: 100 fine-needle aspirated specimens [50 confirmed by culture/smear/cytology, 20 clinically suspected, and 30 controls], processed in the mycobacteriology division of department of microbiology were subjected to TruPlus and TruRif, Xpert Ultra and multiplex PCR. The results of TBLA detection were compared against composite reference standard (CRS) and those of rifampicin resistance were compared against phenotypic drug susceptibility testing and rpoB gene sequencing. RESULTS: In comparison to CRS, the diagnostic yield of TruPlus, Xpert Ultra and MPCR was 77.14%, 59.18% and 84.28%, respectively; with substantial agreement for TruPlus (k = 0.66) and MPCR (k = 0.76) and moderate for Xpert Ultra (k = 0.60). TruRif reported four cases as RifR and Xpert Ultra reported two. On comparing with phenotypic DST and gene sequencing, only two cases of RifR were confirmed, hence TruRif reported false-RifR in two cases. CONCLUSION: TruPlus could be used as a reliable tool for diagnosing TBLA. The reporting of RifR by TruRif should be confirmed by phenotypic DST or gene sequencing.

There is a lack of objective tools for monitoring treatment response in extrapulmonary tuberculosis (EPTB). This study aimed to explore the utility of inflammatory biomarkers from the dry blood spots (DBS) as a tool for monitoring treatment response in EPTB. In a prospective cohort study, 40 inflammatory biomarkers were investigated in DBS samples from 105 EPTB cases using a Luminex platform. The samples were taken before, and, at the end of the 2nd and 6th months of treatment. A total of 11 inflammatory host biomarkers changed significantly with treatment in all EPTB patients. CXCL9/MIG, CCL20, CCL23, CXCL10/IP-10, CXCL1, CXCL2, and CXCL8 significantly declined in our cohort of EPTB (48 TB pleuritis and 57 TB lymphadenitis) patients at both time points. A biosignature consisting of MIG, CCL23, and CXCL2, corresponded with the treatment response in 81% of patients in the 2nd month and 79% of patients at the end of treatment. MIG, CCL23, IP-10, and CXCL2 changed significantly with treatment in all patients including those showing partial clinical response at the 2nd month of treatment. The changes in the levels of inflammatory biomarkers in the DBS correspond with the treatment success and can be developed as a routine test in low-resource settings.

HISTORY: The 37 year old patient was admitted to hospital with persisting fever for 4 weeks. He had a history of weight loss, night sweat and cough. Antipyretic treatment with Paracetamol and up to ineffectiveness therapy with Ibuprofen was taken by the patient. FINDINGS AND DIAGNOSIS: Fever and poor general condition were obvious on time of admission. The ECG showed tachycardia. Liver values were increased. X-ray of the chest showed a central mass on the right site. On computed tomography there was a finding of a possibly necrotic tumour close to central vessels. The patient developed a prolonged thrombocytopenia and bleeding on several sites. Further diagnostic approaches were difficult to perform. After puncture of the central mediastinal mass and bone marrow we diagnosed an extensive extrapulmonary tuberculosis. Toxic hepatitis was getting worse under medical treatment of tuberculosis. In addition, with thrombocytopenia patient condition reached a critical state. THERAPY AND COURSE: After initiation of prednisolone-treatment up to suspicion of drug- induced thrombocytopenia (D-ITP) and switch of the anti- Tb-regimen the general condition improved. There was repetitive need for transfusion of thrombocytes. CONCLUSIONS: Toxic hepatitis is a possible severe complication of anti-Tb-treatment. A critical evaluation of patients' medication and soon initiation of anti -Tb-treatment is necessary. Especially in patients coming from high tb-incidence regions with history of poor general condition and persisting fever the diagnosis of extrapulmonary tuberculosis and bone marrow infiltration should be taken into account.

Introduction/Rationale: Tuberculosis remains a major public health issue. It is an opportunistic pathology, very common in HIV-immunocompromised persons, classifying it at the WHO stage 4. Ear tuberculosis remains a rare and under-diagnosed clinical form. We report here a case of ear tuberculosis concomitant with pulmonary localization in an HIV-immunosuppressed person on triple antiretroviral therapy aged 32 years hospitalized in Bamako (Mali) to discuss the diagnostic and therapeutic difficulties posed by this rare localization. Description of the case: The patient had a chronic productive cough, otalgia and right chronic purulent otorrhea. The search for acid-resistant bacilli was positive for direct examination in gastric casing fluid and swabbing of the ear pus, confirming the diagnosis of tuberculosis. Anti-tuberculosis treatment instituted for 6 months associated with adjuvants resulted in complete healing of the patient. Discussion/conclusion: Although rare, ear localization must be actively sought. Etiological treatment must be instituted upon confirmation of the diagnosis to avoid complications and sequelae.

BACKGROUND: Extrapulmonary TB (EPTB) is more difficult to diagnose than pulmonary TB. The delayed management of EPTB can lead to complications and increase the socio-economic burden.METHODS: Patients newly diagnosed with EPTB were retrospectively enrolled from 11 general hospitals in South Korea from January 2017 to December 2018. The basic characteristics of patients were described. Univariable and multivariable analyses were performed between early and delayed diagnosis groups to identify risk factors for delayed diagnosis and treatment in EPTB.RESULTS: In total, 594 patients were enrolled. Lymph node TB (28.3%) was the predominant form, followed by abdominal (18.4%) and disseminated TB (14.5%). Concurrent lung involvement was 17.8%. The positivity of diagnostic tests showed no significant difference between the two groups. Acute clinical manifestations in disseminated, pericardial and meningeal TB, and immunosuppression were associated with early diagnosis. Delayed diagnosis was associated with outpatient clinic visits, delayed sample acquisition and diagnostic departments other than infection or pulmonology.CONCLUSION: The delay in diagnosis and treatment of EPTB was not related to differences in microbiological characteristics of Mycobacterium tuberculosis itself; rather, it was due to the indolent clinical manifestations that cause referral to non-TB-specialised departments in the outpatient clinic and delay the suspicion of TB and diagnostic testing.
