Clinical Profile and Predictors of Intensive Care Admission in Neonicotinoid Poisoning in a Tertiary Care Hospital in South India.

Background and objectives: Neonicotinoids are a newer class of pesticides that are believed to cause predominantly mild toxicity in humans. This study aimed to describe the clinical features of neonicotinoid poisoning and identify predictors of severe toxicity. Materials and methods: This retrospective study included all patients with neonicotinoid poisoning admitted to a Tertiary Care Center in India over an 18-year period. Clinical and laboratory features were compared against outcomes to identify predictors of the need for intensive care admission. Results: Twenty-eight patients were included in the study of which 28.6% had severe disease requiring ICU admission. A higher respiratory rate, blood lactate level, SOFA, and qSOFA scores as well as a lower Glasgow coma score at presentation predicted ICU admission. First-generation compounds and imidacloprid consumption were associated with longer ICU stays and a longer duration of invasive ventilation. Conclusion: Neonicotinoid compounds can cause significant toxicity with oral ingestion. Imidacloprid and other first-generation compounds were associated with more severe toxicity requiring intensive care. Simple clinical parameters assessed at presentation can be used to predict severe disease and the need for ICU care. Larger, prospective studies are required to confirm these findings.

Cardioembolic Stroke in Sinus of Valsalva Aneurysm, A Case Report.

A case of cardioembolic stroke in a patient with sinus of Valsalva aneurysm. The patient presented with chief complaints of syncope, with slurring of speech and a history of deviation of angle of mouth to the right side, which resolved over one day. Examination revealed no focal neurological deficit. CT Brain revealed a lacunar infarct over the left frontal cortex. Echocardiography showed sinus of Valsalva aneurysm of the non-coronary cusp. Hence a diagnosis of cardioembolic stroke secondary to thrombus present in the sinus of Valsalva of the aneurysm was considered. This is a rare presentation of Sinus of Valsalva as a cardioembolic stroke.

Hoffman syndrome with the classic sign of myoedema and an unusual finding of systolic heart failure.

A man in his 20s presented with a 6-year history of calf muscle hypertrophy, proximal muscle weakness and muscle cramps. Along with this, he also had patchy hair loss, facial puffiness and slurring of speech. On examination, he had mild symmetrical proximal muscle weakness, a delayed relaxation phase of his deep tendon reflexes and a rare neurological sign of myoedema. His laboratory investigations revealed elevated thyroid-stimulating hormone levels with high creatine kinase levels, and an echocardiogram showed left ventricular systolic dysfunction. He was diagnosed with Hoffman syndrome, a rare pseudohypertrophic myopathy associated with severe and prolonged hypothyroidism. He had an excellent response to thyroid hormone replacement.

Genomic analysis of Brucella melitensis reveals new insights into phylogeny and evolutionary divergence.

PURPOSE: Brucellosis is a bacterial zoonotic disease caused by genus Brucella. The disease is often transmitted to humans by direct or indirect contact with infected livestock or from laboratory exposure. In this study two clinical isolates of Brucella melitensis were subjected to whole genome sequencing (WGS) using Ion Torrent PGM and Oxford Nanopore MinIon platform. METHODS: The two hybrid complete genomes were subjected to core gene SNP analysis to identify the relative evolutionary position. To distinguish between the various lineages of B. melitensis, Pangenome analysis was carried out. RESULTS: Phylogenetic analysis revealed that both the study isolates (ST8) clustered along the other Asian isolates that formed genotype II. Genome wide analyses of 326 B melitensis isolates suggests 2171 gene clusters were shared across all the genomes while 3552 gene clusters were considered as accessory genes. CONCLUSION: Here we attempted to provide the gain and loss of six unique genes that defined the phylogenetic lineages and complex evolutionary process. As the severity and prevalence of human brucellosis is increasing a better understanding of Brucella genomics and transmission dynamics is needed.

Is it time to move on to gene-based Salmonella typing: Evidence and implications.

Non-typhoidal Salmonella (NTS) is the major cause of foodborne infections globally, with considerable morbidity and mortality. The accurate identification of Salmonella serovars is important in disease management and public health surveillance. However, traditional serotyping methods are laborious, time-consuming and may produce ambiguous results. In this study, we evaluated traditional serotyping and seven gene-based multilocus sequence typing (MLST) methods to determine the serogroups of Salmonella strains. This study analysis suggests that MLST based serotyping is accurate in serogroup identification and discrimination of Salmonella serovars compared to the traditional serotyping method and can be implemented in routine clinical practice.

Clinical and Genomic Evolution of Carbapenem-Resistant Klebsiella pneumoniae Bloodstream Infections over Two Time Periods at a Tertiary Care Hospital in South India: A Prospective Cohort Study.

INTRODUCTION: The objective of this study was to examine the evolution of carbapenem-resistant Klebsiella pneumoniae (CRKp) infections and their impact at a tertiary care hospital in South India. METHODS: A comparative analysis of clinical data from two prospective cohorts of patients with CRKp bacteremia (C1, 2014-2015; C2, 2021-2022) was carried out. Antimicrobial susceptibilities and whole genome sequencing (WGS) data of selected isolates were also analyzed. RESULTS: A total of 181 patients were enrolled in the study, 56 from C1 and 125 from C2. CRKp bacteremia shifted from critically ill patients with neutropenia to others (ICU stay: C1, 73%; C2, 54%; p = 0.02). The overall mortality rate was 50% and the introduction of ceftazidime-avibactam did not change mortality significantly (54% versus 48%; p = 0.49). Oxacillinases (OXA) 232 and 181 were the most common mechanisms of resistance. WGS showed the introduction of New Delhi metallo-ß-lactamase-5 (NDM-5), higher genetic diversity, accessory genome content, and plasmid burden, as well as increased convergence of hypervirulence and carbapenem resistance in C2. CONCLUSIONS: CRKp continues to pose a significant clinical threat, despite the introduction of new antibiotics. The study highlights the evolution of resistance and virulence in this pathogen and the impact on patient outcomes in South India, providing valuable information for clinicians and researchers.

Intravenous Doxycycline, Azithromycin, or Both for Severe Scrub Typhus.

BACKGROUND: The appropriate antibiotic treatment for severe scrub typhus, a neglected but widespread reemerging zoonotic infection, is unclear. METHODS: In this multicenter, double-blind, randomized, controlled trial, we compared the efficacy of intravenous doxycycline, azithromycin, or a combination of both in treating severe scrub typhus. Patients who were 15 years of age or older with severe scrub typhus with at least one organ involvement were enrolled. The patients were assigned to receive a 7-day course of intravenous doxycycline, azithromycin, or both (combination therapy). The primary outcome was a composite of death from any cause at day 28, persistent complications at day 7, and persistent fever at day 5. RESULTS: Among 794 patients (median age, 48 years) who were included in the modified intention-to-treat analysis, complications included those that were respiratory (in 62%), hepatic (in 54%), cardiovascular (in 42%), renal (in 30%), and neurologic (in 20%). The use of combination therapy resulted in a lower incidence of the composite primary outcome than the use of doxycycline (33% and 47%, respectively), for a risk difference of -13.3 percentage points (95% confidence interval [CI], -21.6 to -5.1; P = 0.002). The incidence with combination therapy was also lower than that with azithromycin (48%), for a risk difference of -14.8 percentage points (95% CI, -23.1 to -6.5; P<0.001). No significant difference was seen between the azithromycin and doxycycline groups (risk difference, 1.5 percentage points; 95% CI, -7.0 to 10.0; P = 0.73). The results in the per-protocol analysis were similar to those in the primary analysis. Adverse events and 28-day mortality were similar in the three groups. CONCLUSIONS: Combination therapy with intravenous doxycycline and azithromycin was a better therapeutic option for the treatment of severe scrub typhus than monotherapy with either drug alone.

Accuracy of Xpert MTB/RIF Ultra for the diagnosis of tuberculosis in adult patients: a retrospective cohort study.

OBJECTIVES: The value of the "trace" result in Xpert Ultra for diagnosing active tuberculosis (TB) remains unclear. Our study evaluated the diagnostic accuracy of Xpert MTB/RIF Ultra (Xpert Ultra) (Cepheid, Sunnyvale, USA) over Xpert MTB/RIF (Xpert) (Cepheid, Sunnyvale, USA) and mycobacterial culture when compared with a composite reference standard (CRS). METHODS: A retrospective single-center observational study was conducted in a tertiary care hospital in South India. Over three months, patients (aged ≥15 years) data on Xpert Ultra tests and mycobacterial culture of pulmonary and extrapulmonary samples were extracted from their electronic medical records. Patients were defined as TB cases based on the CRS criteria. Sensitivity, specificity, positive and negative predictive values of diagnostic tests were calculated by comparing them to the CRS. RESULTS: Xpert Ultra was more sensitive (87.8%) than Xpert (72.1%) and culture (44.1%). The specificity of Xpert Ultra was lower (98.1%) than those of Xpert (100%) and culture (100%). The sensitivity (92%) and specificity (100%) of Xpert Ultra were highest when performed on pus samples. CONCLUSIONS: Xpert Ultra with the trace category is superior to the conventional Xpert, and mycobacterial culture in identifying TB.

The role and diagnostic accuracy of serology for COVID-19.

BACKGROUND: The role and performance of various serological tests for the diagnosis of COVID-19 are unclear. This study aimed to evaluate the performance of seven commercially available serological assays for SARS-CoV-2 antibodies by testing COVID-19 cases and controls. METHODS: Adult patients with fever for > 5 days, admitted to a tertiary-care teaching hospital in South India, were enrolled prospectively between June and December 2020. SARS-CoV-2 RT-PCR confirmed patients were classified as cases, and patients with febrile illness with laboratory-confirmed alternative diagnosis and healthy participants were controls. All participants were tested with SCoV-2 Detect™ IgM ELISA kit and SCoV-2 Detect™ IgG ELISA kit (InBios International, Seattle, USA) (Inbios), SARS-CoV-2 Total and SARS-CoV-2 IgG (Siemens Healthcare Diagnostics Inc., Tarrytown, USA) (Siemens), Roche Elecsys® Anti-SARS-CoV-2 (Roche Diagnostics, Rotkreuz, Switzerland) (Roche), Abbott SARS-CoV-2 IgG (Abbott Diagnostics, IL, USA) (Abbott), and Liaison® SARS-CoV-2 S1/S2 IgG (DiaSorinS.p.A., Saluggia, Italy) (Liaison). The sensitivities, specificities, positive predictive values (PPV), negative predictive values (NPV), and accuracies were compared. RESULTS: There were 303 participants: 153 cases and 150 controls. ELISA detecting anti-S protein antibody was more sensitive (88.9% for IgG and 86.3% for IgM) than the CLIAs (82.4% for total antibodies and 76.5-85.6% for IgG). Among CLIAs, Roche IgG was most sensitive (85.6%) followed by Abbott (83%) and Liaison (83%). Abbot had the best PPV (88.8%) and was more specific (89.3%) than Liaison (82%) and Roche (82%). Siemens IgG was less sensitive (76.5%) than Siemens Total (82.4%). The specificity of all the serological assays was modest (75-90%). Antibody test positivity increased with the duration of illness reaching 90% after 10 days of illness. When cases were compared against pre-pandemic controls, the IgG gave excellent specificity (98-100%). For seroprevalence studies, InBios IgG had the best accuracy (90.8%) with 88.9% sensitivity and 97.6% specificity. CONCLUSION: The serological assays are important adjuncts for the diagnosis of COVID-19 in patients with persistent symptoms, especially in the second week of illness. The value of serological diagnostic tests is limited in the first week of illness and they provide additional value in seroprevalence studies. The diagnostic accuracy of the ELISA and CLIA platforms were comparable.

Treatment of COVID-19 Acute Respiratory Distress Syndrome With a Tabletop Noninvasive Ventilation Device in a Respiratory Intermediate Care Unit.

Objective: To study the outcomes of noninvasive ventilation (NIV) administered through a tabletop device for coronavirus disease 2019 acute respiratory distress syndrome in the respiratory intermediate care unit (RIMCU) at a tertiary care hospital in India. Patients and Methods: We retrospectively studied a cohort of hospitalized patients deteriorating despite low-flow oxygen support who received protocolized management with positive airway pressure using a tabletop NIV device in the RIMCU as a step-up rescue therapy from July 30, 2020 to November 14, 2020. Treatment was commenced on the continuous positive airway pressure mode up to a pressure of 10 cm of H2O, and if required, inspiratory pressures were added using the bilevel positive air pressure mode. Success was defined as weaning from NIV and stepping down to the ward, and failure was defined as escalation to the intensive care unit, the need for intubation, or death. Results: In total, 246 patients were treated in the RIMCU during the study period. Of these, 168 received respiratory support via a tabletop NIV device as a step-up rescue therapy. Their mean age was 54 years, and 83% were men. Diabetes mellitus (78%) and hypertension (44%) were the commonest comorbidities. Treatment was successful with tabletop NIV in 77% (129/168) of the patients; of them, 41% (69/168) received treatment with continuous positive airway pressure alone and 36% (60/168) received additional increased inspiratory pressure via the bilevel positive air pressure mode. Conclusion: Respiratory support using the tabletop NIV device was an effective and economical treatment for coronavirus disease 2019 acute respiratory distress syndrome. Further studies are required to assess the appropriate time of initiation for maximal benefits and judicious utilization of resources.

Novel linear plasmids carrying vanA cluster drives the spread of vancomycin resistance in Enterococcus faecium in India.

OBJECTIVES: The genetic basis for the spread of vancomycin resistance in Enterococcus faecium is largely unexplored in India. The present study aimed to investigate the plasmid diversity and variation of Tn1546 associated with vanA harbouring VREfm isolates. METHODS: A total of 122 VREfm isolates collected from blood cultures were included in this study. MLST analysis was performed on all isolates, and they were also screened for the presence of vanA and vanB genes. Whole genome sequencing was performed for a subset of fifteen VREfm isolates belonging to ST1643. RESULTS: All of the 122 VREfm isolates carried the vanA gene. Twenty-four different sequence types were seen; of these, ST1643, ST80 and ST17 were predominant. Whole genome sequencing was performed on 15 VREfm isolates belonging to ST1643. For eight isolates the vanA gene was found on pRUM-like circular plasmids, and for the remaining seven isolates, the vanA gene was found on the linear plasmids. Novel Tn1546 variants carrying vanA were found on both circular and linear plasmids. Interestingly, co-presence of vanA and optrA were seen in the backbone of three linear plasmids. CONCLUSION: Multiple vanA-carrying plasmids and Tn1546-like elements were involved in the dissemination of vancomycin resistance in VREfm. The co-occurrence of Tn1546 carrying vanA and Tn554 family transposon carrying optrA on the backbone of plasmids is worrisome. The dissemination of such plasmids may pose treatment and infection control challenges.

Clinical efficacy of novel combinations of older beta-lactam and beta-lactamase inhibitors: Where are the evidences?

India is well known for the rampant growth of ESBLs that jeopardized the clinical utility of standalone beta-lactam. Pharmaceutical organizations fancied to rescue these beta-lactams by combining them with generic beta-lactamase inhibitors despite such combinations were never investigated in non-clinical or clinical studies. Lack of stringency in regulatory review practices allowed the market entry of these combinations. CSE 1034 (ceftriaxone, sulbactam and EDTA) and cefoperazone sulbactam are the most irrational antibiotics in clinical use. The effectiveness of such combinations relies on multiple factors such as relative beta-lactamase stability of the standalone beta-lactam, the inhibitory potency of the beta-lactamase inhibitor and more importantly the adequacy of the dose incorporated in the formulation. Unfortunately, none of the unconventional BL-BLI inhibitor combinations marketed in India has been subjected to such evaluations. Therefore, their therapeutic utility is uncertain. Besides questionable therapeutic utility, sub-optimal exposures would lead to the selection of resistant clones.

Stenotrophomonas isolates in a tertiary care centre in South India.

PURPOSE: Stenotrophomonas maltophilia is an emerging multi-drug resistant pathogen increasingly isolated in India. This study aimed to identify patients from whom Stenotrophomonas maltophilia had been isolated and assess predictors of mortality in this population. METHODS: This was a retrospective cohort study of hospitalized patients with a positive culture for S. maltophilia over a 3-year period. Clinical details and laboratory results were assessed from hospital records. Bivariate and multivariate analysis was used to identify risk factors for mortality. RESULTS: One hundred and nineteen patients (mean age 48.6 years) were included in the study. Of these, 111 patients were hospitalized for at least 48 â€‹hours prior to culture and 98 were admitted in the intensive care unit. Bivariate analysis revealed multiple associations with mortality, including a background of renal, cardiac, autoimmune disease, recent carbapenam use and COVID-19 infection and increasing ventilatory requirement, lower PaO2/FiO2 (P/F) ratio, vasopressor use, thrombocytopenia, and hypoalbuminemia at the time of positive isolate. Multivariate analysis showed that autoimmune disease [OR 27.38; 95% CI (1.39-540)], a P/F ratio of less than 300 [OR 7.58; 95% CI (1.52-37.9)], vasopressor requirement [OR 39.50; 95% CI (5.49-284)] and thrombocytopenia [OR 11.5; 95% CI (2.04-65.0)] were statistically significantly associated with increased mortality, while recent surgery and receipt of antibiotics [OR 0.16; 95% CI (0.03-0.8)] targeted against S. maltophilia were associated with decreased mortality. CONCLUSION: Stenotrophomonas maltophilia is primarily isolated in patients in the intensive care unit. In our study the need for vasopressors, autoimmune disease, lower P/F ratios and thrombocytopenia were associated with higher mortality. The association of targeted antibiotics with reduced mortality suggests that the pathogenic role of S. maltophilia should not be underestimated. This finding needs to be confirmed with larger, prospective studies.

Direct Costs of Healthcare among Patients with Deliberate Self-harm: A Pilot Study from a Tertiary Care Hospital in South India.

Background: Deliberate self-harm (DSH) in developing nations has a significant impact on health and economic conditions of patients and families. Materials and methods: This retrospective study aims to study the cost of hospitalization and the factors affecting the cost of medical care. Adult patients with a diagnosis of DSH were included. Results: A total of 107 patients were included with the most common type of poison consumed being pesticides (35.5%) followed by a tablet overdose (31.8%). There was a male preponderance with a mean (SD) age of 30.04 (9.03) years. The median cost of admission was ₹13,690 (USD 195.57); DSH with pesticide increased the cost of care by 67% as compared to non-pesticides. Other factors which increased the cost were need for intensive care, ventilation, use of vasopressors, and development of ventilator-associated pneumonia (VAP). Conclusions: Pesticide-based poisoning is the most frequent cause of DSH. Among different types of DSH, pesticide poisoning is associated with a higher direct cost of hospitalization.

Bedside lung ultrasonography: comparison with chest radiography (BLUR), a diagnostic study in a developing country.

BACKGROUND: This study determines the diagnostic utility of lung ultrasonography (LUS) in a medical ward in a developing country. In a low resource country like India, we hope that use of lung ultrasound in primary and secondary hospitals will assist in earlier and better bedside diagnosis. METHODS: This prospective diagnostic study was done to test the diagnostic accuracy of LUS against a composite reference standard, which included clinical history and examination, basic laboratory investigations, imaging and the diagnosis at discharge. We evaluated 321 consecutive patients, admitted in our medical wards with an LUS within 24 hours of the chest radiograph being done. FINDINGS: Between August 2016 and August 2017, we enrolled 321 patients. The sensitivity and specificity of the LUS for all pathologies were found to be 82.5% (76.50 to 87.20) and 78.2% (69.09 to 85.26) respectively. A subgroup analysis including the patients in whom CT was part of the composite reference standard showed sensitivity and specificity of 87.9% and 92.9% for all lung pathologies. It was found that there was superior sensitivity and specificity of LUS compared with chest radiograph in a subgroup analysis of pulmonary oedema and acute respiratory distress syndrome (ARDS). INTERPRETATION: We found that the LUS was better than chest radiograph and as good as CT in most pathologies, especially pulmonary oedema and ARDS. We believe that training in the basics of bedside LUS must be part of the medical curriculum and a low-cost ultrasound machine must be made available in medical wards, so that clinical diagnosis can be supplemented with this tool. In a low resource setting like India, where access to chest radiograph and CT may be difficult particularly in a rural setup, expertise in LUS would be helpful in easy bedside diagnosis and saving cost on a CT scan.

Utility of positron emission tomography-computed tomography in the evaluation of fever of unknown origin in a resource-limited tropical nation.

Positron emission tomography-computed tomography (PET-CT) has been used as an imaging modality in workup of fever of unknown origin (FUO). The aim of our study is to evaluate the diagnostic utility of PET-CT in FUO workup in a resource-limited setting. We also looked at laboratory parameters as predictors of contributory PET-CT scans and propose an algorithm for evaluation of FUO in resource-limited tropical regions. This retrospective observational study included patients admitted for FUO workup under general medicine in a teaching hospital in South India from June 2013 to May 2016. PET-CT was done when the patient remained undiagnosed after a detailed clinical assessment and first- and second-tier investigations. Among 43 patients included in our study, a definite diagnosis was established in 74% (32). Noninfectious inflammatory diseases, infections, malignancies, and miscellaneous diseases were diagnosed in 37.2% (16/43), 23.3% (10/43), 9.3% (4/43), and 4.7% (2/43), respectively. Tuberculosis was the single most common disease seen in 20.9% (9/43). PET-CT scans were contributory toward establishment of final diagnosis in 90.7% (39/43). High C-reactive protein (CRP) and aspartate aminotransferase (AST) levels were associated with contributory PET-CT scans (P = 0.006 and 0.011, respectively). PET-CT delineating organ/tissue for diagnostic biopsy was associated with final diagnosis of infectious disease (P = 0.001). Sensitivity, specificity, and positive and negative predictive value of PET-CT scans were 76.9% (20/26), 33.3% (2/6), 83% (20/24), and 25% (2/8), respectively. High CRP and AST were predictors of contributory PET-CT scans. PET-CT scans have high sensitivity and positive predictive value when used in evaluation of FUO. Although it is a useful tool in FUO workup, especially in the diagnosis of tropical infections, PET-CT should be done after a comprehensive clinical assessment and basic investigations.

Evaluation of intracranial vasculitis in tuberculous meningitis using magnetic resonance vessel wall imaging technique.

Background: Tuberculous meningitis (TBM) is a global health problem with important complications such as acute infarcts secondary to vasculitis contributing to adverse outcomes. The objective of this study is to assess intracranial vasculitis in patients with TBM, either during their initial diagnosis or during follow-up while on standard antituberculous therapy. Methods: Ten patients with TBM underwent magnetic resonance (MR) based vessel wall imaging (VWI) to identify intracranial vasculitis (five patients during their initial presentation and the other five patients during their follow-up visit). Results: Vasculitis was seen in 60% of the patients wherein 70% of their intracranial vessels were affected. Acute and chronic infarcts were seen in four and two patients respectively, one of whom had both acute and chronic infarcts. Leptomeningeal enhancement and basal cisternal tuberculomas were frequently seen in patients with vasculitis. Vasculitis was also seen many days after the commencement of the antituberculous therapy thus explaining late-onset infarcts in this disease. Conclusion: Intracranial vasculitis is common in the patient with TBM. MR-based VWI technique has the potential for infarct risk assessment and to help guide the treatment for its possible prevention.

Thromboelastograph:A prognostic marker in sepsis with organ dysfunction without overt bleeding.

BACKGROUND: Coagulation abnormalities are not infrequent in sepsis. It is unclear if abnormalities in thromboelastogram (TEG) are associated with mortality in patients with severe sepsis without overt bleeding. MATERIALS AND METHODS: In this prospective study, patients were categorised as those with normal coagulation, hypercoagulable or hypercoagulable state based on admission TEG parameters (R time, K time, Maximum amplitude (MA), α angle). Their association with mortality was explored using Fisher's exact and Mann-Whitney U test as appropriate. RESULTS: The study cohort (n = 87; 49 male) with median (IQR) age 51 (42-60) years and admission SOFA score 8 (6-11) included scrub typhus (24.1%), pneumonia (22.6%) and urosepsis (10.3%). Non-invasive and invasive ventilation and vasopressors were required in 28.1%, 68.9% and 74%, respectively. Mortality was 24.1%. Based on R time, K time and α angle, 3.5% to 9.3% had a hypercoagulable state and 26.7 to 29.9% were hypocoagulable. Prolonged R time (p = 0.04) and reduced alpha angle (p = 0.01) in patients with hypocoagulable state was associated with mortality. K time, α angle and MA were significantly different in patients requiring transfusion (p < 0.001). CONCLUSION: A subset of patients with severe sepsis without overt bleeding are hypocoagulable. Hypocoagulability is associated with mortality and need for transfusion.

Role of cerebrospinal fluid C-reactive protein in tuberculous meningitis.

Background: Tuberculosis (TB) is still a significant health problem worldwide. Central nervous system TB amounts to 10% of all cases of TB. Despite advances in the pharmacological management of TB, the overall outcomes remain poor with significant mortality and morbidity. There are no predictors for neurological outcomes in tuberculosis meningitis (TBM). In this study, we aimed to evaluate the role of cerebrospinal fluid (CSF) C-reactive protein (CRP) in predicting mortality and neurological outcome in TBM. Method: In this observational study, all patients with TBM were recruited prospectively over a 12-month duration. Baseline demographic data, laboratory parameters, and Imaging findings were collected. CSF CRP was obtained on the CSF sample collected at the time of diagnosis. Patients were followed up at 3 months to assess neurological status and mortality. Results: Seventy-one patients with TBM were recruited in this study. The overall mortality in this study was 22.5% of patients. The primary composite outcome of mortality and adverse neurological outcome occurred in 40.8%. The CSF CRP levels ranged between 0.1 and 4.8 mg/dl, and the mean CSF CRP level was 1.11 mg/dl. The Relative risk for a patient with high CSF CRP to develop adverse outcome was 1.84 (P = 0.038). CSF CRP was a good predictor of mortality with a relative risk of 2.92 (P = 0.027). Stroke in TBM had a high incidence of 47.9% and a relative risk of 3.42 for an adverse neurological outcome. CSF CRP did not predict the occurrence of stroke. Hydrocephalus and elevated intracranial pressure were good predictors of stroke. Conclusion: TBM is a disease with significant mortality and morbidity. CRP level in the CSF can be measured, but a highly sensitive scale may be needed as the mean values were much lower compared to the serum values. CSF CRP Levels showed significant associations with adverse outcomes and mortality.
