RESUMEN

INTRODUCTION: Tuberculosis remains a global health problem worldwide and the risk progression of Tuberculosis to Drug Resistant Tuberculosis is influenced by various factors. These include immunocompromised status, past history of tuberculosis, life style and nutritional level. Hence, identifying the population at risk of multidrug-resistant tuberculosis is essential and may help in developing appropriate case-finding strategies. Therefore, the present study was designed to study the contributing risk-factors associated with Drug resistant Tuberculosis. MATERIALS AND METHODS: In this prospective observational study, we assessed 189 Pulmonary tuberculosis diagnosed patients during the period of 2 years at government recognized tertiary care centers. Data was collected from all these patients checked to investigate risk factors associated with Drug resistant tuberculosis development by multivariant analysis. RESULTS: Of the 189 participants, 36 were diagnosed with drug resistant tuberculosis and 153 with drug sensitive tuberculosis. Factors associated with drug resistant tuberculosis include low-weight (OR 8.50; p = 0.0008430991), low-BMI (p = 0.0000527166), lower economic status (OR-2.1351; p = 0.048608696) and tobacco (OR-4.5192; p = 0.0023003189) were found clinically and statistically significant in development of drug resistant tuberculosis. Binary logistic regression was performed to ascertain the effects of various statistically significant factors. Drug resistant tuberculosis patients were 7.77 times more likely to be tobacco users than drug sensitive tuberculosis. CONCLUSIONS: Our study suggests that, there is a compelling and urgent need for increasing public awareness, initiating better nutrition and food programs, regular screening, and better management & control of MDR-TB.

RESUMEN

Introduction: COVID-19 is a disease caused by the severe acute respiratory syndrome coronavirus 2 that has appeared as a global pandemic in recent times. Currently, the transmission rate has slowed down significantly, but the definite pathological reason behind this is still unknown. Therefore, the prevalence of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibody must be studied to establish the relation between the rate of transmission and antibody presence. Materials and Methods: A clinical assessment was performed to evaluate the seroprevalence of SARS-CoV-2 Immunoglobulin G (IgG) antibodies among 299 healthy volunteers in the period of February to May 2021. Serum samples were analyzed using chemiluminescent microparticle immunoassay (CMIA) technology to detect the presence of IgG antibodies. Result: It was observed that 21% of the participants were seropositive, and 78% of the population was seronegative across the different genders. This confirmed that the generation of antibodies is independent of gender. Simultaneously, a t-test was performed that further suggested no statistical correlation between gender and seroprevalence. Moreover, a comprehensive analysis was performed to establish the relation between age and blood group with the seroprevalence. However, there was no statistical relationship found among these parameters. Conclusion: This study assisted in examining the underlying causes of high or low seroprevalence among healthy volunteers.

RESUMEN

PURPOSE: Diabetes mellitus (DM-II) is a metabolic disorder either due to reduced insulin production or reduced insulin sensitivity. Diabetic foot ulcer (DFU) is one of the most devastating complications of DM-II. This study was performed to assess commonly isolated micro-organisms and their anti-microbial sensitivity pattern in diabetic foot ulcers in a tertiary care centre in Western Maharashtra. METHODS: Adult patients with a known case of DM-II with foot lesions, suspected to be a Diabetic Foot Infections (DFIs) at the tertiary care hospital from Aug 2022 to Sept 2022 were included in the study. After obtaining informed written consent, pus sample was collected with sterile swab from lesion's base and submitted to Microbiology Laboratory for aerobic culture and sensitivity. RESULTS: Out of 56 enrolled patients, 47 (83.9%) patients tested positive for bacteriological growth and there was 'no growth' in 9 (16.07%) patients at the end of 48 h of aerobic incubation. There was male preponderance and patients were in age group of 35-85 years. The most commonly isolated micro-organisms were P. aeruginosa (17.8%), followed by S. aureus (14.2%), K. pneumonia and P. mirabilis (12.5% each). The resistance markers observed was ESBL producer, AmpC producer, MBL producer, Methicillin resistance and Inducible Clindamycin Resistance (ICR). CONCLUSION: Due to the injudicious use of antibiotics, antibiotic resistance has been increased in all types of soft tissue infections. The empirical formula for the treatment of DFIs should be decided for given geographical reasons according to antimicrobial susceptibility profile from particular geographical area or health care institute.

RESUMEN

Pott's disease, also known as TB spondylitis, is a very uncommon extrapulmonary infection caused by Mycobacterium tuberculosis. As its prevalence is not high it can easily be underdiagnosed. Magnetic resonance imaging (MRI), computed tomographic (CT) guided needle aspiration, or biopsy are known to be the best techniques for early histopathological diagnosis along with confirmation by microbiological results. Ziehl Neelson stain (ZN) can detect Mycobacterium infections when clinically suspected samples are adequate and optimally stained. No single method or simple guideline can diagnose spinal tuberculosis. Early diagnosis and prompt treatment are necessary to prevent permanent neurological disability and to minimize spinal deformity. We are reporting three cases of Potts disease which could have been easily missed if we would have relied on one single investigation.

RESUMEN

Objectives: Tuberculosis (TB) of lymph node (TB lymphadenitis) is one of the most common forms of extrapulmonary TB (EPTB) whose diagnosis is critically challenging. Although new diagnostic methods have been developed, especially in patients without a history of TB, the cervical tuberculous lymphadenitis diagnosis is still elusive. This study assessed the applicability of GeneXpert in early diagnosis of EPTB, especially cervical lymphadenopathy. Materials and Methods: The study was conducted in a tertiary care hospital from January 2018 to December 2020 at the department of microbiology. All the samples of cervical lymph node tissue and lymph node aspirate were followed as per the routine protocol for mycobacterial identification. The sample was divided into two parts: one was used for the new molecular-based GeneXpert MTB/RIF assay and the second one was tested by direct and concentrated acid-fast bacilli microscopy by Z-N staining and culture for the detection of MTB. Results: Among the 145 samples tested, the GeneXpert detected the DNA of MTB in 89 samples (61.37%), whereas the culture test was positive in 42 (28.93%) specimens. GeneXpert also detected 7 rifampicin resistance cases. GeneXpert sensitivity and specificity results were assessed according to culture results. The sensitivity and specificity of the GeneXpert assay were 85.71% and 48.54%, respectively. Conclusion: GeneXpert MTB/RIF should be used in conjunction with clinical presentation and other molecular investigation in nonrespiratory specimens.

RESUMEN

Diagnosing extra-pulmonary tuberculosis is a challenge that can confound even the most practiced clinicians as clinical manifestations are vague, non-specific and typical chest radiograph findings may not be evident till late in the disease. Conventional methods for mycobacteriological culture and drug susceptibility testing are slow and cumbersome. Novel technologies for rapid detection of Mycobacterium tuberculosis and its anti-TB drug resistance have therefore become a priority hence with the development of molecular line probe assays are most advanced. Herewith we are reporting a case of splenic tuberculosis in an immunocompromised patient for its rarity and to emphasis the fact that such patients can be diagnosed early for better treatment outcome to enhance the longevity if a health setup possesses all the modern diagnostic services.
