Acute febrile encephalopathy is a common syndrome in the tropics with high mortality encountered by emergency physicians. In order to study the aetiology of acute febrile encephalopathy and its mortality and functional outcome over one year, data on all patients >18 years of age with short duration of fever (

Aim Heart failure is a global problem that is increasing in prevalence. We undertook the initiative to compile the Vellore Heart Failure Registry (VHFR) to assess the clinical profile, mortality, risk factors and economic burden of heart failure by conducting a prospective, observational, hospital-based cohort study in Vellore, Tamil Nadu. Methods and results This study was a prospective observational cohort study conducted at the Christian Medical College and Hospital, Vellore, between January 2014 and December 2016. A total of 572 patients who satisfied the Boston criteria for “definite heart failure” were included and the primary outcome was all-cause mortality. The median duration of hospital stay was eight days and the in-hospital, one, three and six month mortalities were 13.25%, 27.3%, 32.53% and 38.15%, respectively. The median duration of survival was 921 days. Readmission for heart failure constituted 42%, and the most common cause of decompensation was an infection(31.5%). The presence of cyanosis at admission, history of previous stroke or transient ischemic attack, and American College of Cardiology (ACC)/American Heart Association (AHA) stage D at the time of discharge were independently associated with mortality at six months. The median total direct cost of admission was INR 84,881.00 ($ 1232.34) Conclusion The VHFR cohort had younger, more diabetic, and fewer hypertensive subjects than most cohorts. Admission for heart failure is a catastrophic health expenditure. Attempts should be made to ensure a reduction in readmission rates by targeting goal-directed therapy. As the most common cause of acute decompensation is pneumonia, vaccinating all patients before discharge may also help in this regard.

Background. Prothrombin (PT) G20210A is one of the genetic polymorphisms associated with thrombophilia. Studies show a low prevalence for this polymorphism in Asian populations with only one subject reported from India. We studied the prevalence and association of this polymorphism in patients with arterial and venous strokes and their matched controls in south and north India. Methods. We recruited patients with cerebral venous thrombosis (mean age 37.2 years) and cryptogenic ischaemic stroke (mean age 36.7 years), and age- and sex-matched controls (mean age 37.6 years) from south and north India. Genotyping was carried out using polymerase chain reaction followed by restriction fragment length polymorphism, and the prevalence of the variants among the patients and controls was compared. Results. The heterozygous allele of the polymorphism was detected in both groups with significantly higher prevalence among north Indians (5/154; 3.2%) compared with south Indians (4/516; 0.8%; p = 0.026). Thrombosis as a manifestation of this polymorphism was more among north Indians with 4/82 (4.9%) of patients with ischaemic stroke and cerebral venous thrombosis having this polymorphism compared with south Indian patients 1/72 (1.4%), p = 0.003. Conclusion. PT G20210A is prevalent in India, especially among those from north India. Its role in predisposition to thrombosis needs to be studied further along with other known risk factors.

Context: Tuberculosis (TB) has become the most common opportunistic infection among individuals with human immunodeficiency virus (HIV) infection worldwide and continues to be a major killer resulting in 0.4 million deaths every year. While some of the risk factors for developing TB in HIV-infected individuals are known, identifying other risk factors will help in screening strategies to pick out those at higher risk for closer follow-up. Aims: The aim of this study was to identify the risk factors related to the development of active TB in HIV-infected individuals. Settings and Design: This case–control study among the HIV-infected individuals was carried out at a HIV clinic in a large tertiary care hospital in South India. Methods: HIV-infected individuals >18 years of age with confirmed TB were chosen as cases. For each case, two age- and sex-matched controls, diagnosed to have HIV infection without active TB or history of TB, were included. The potential risk factors for the development of active TB were evaluated using the odds ratios (ORs) and logistic regression analysis. Results: A total of 150 patients, 50 cases (mean age: 39.3 ± 7.2 years) and 100 controls (mean age: 40.2 ± 7.1 years) were included. On univariate analysis, smoking (OR 8.14, 95% confidence interval [CI]: 3.13–21.21; P < 0.001), low body mass index (OR 6.31, 95% CI: 2.75–14.48; P < 0.001), chronic obstructive pulmonary disease (P = 0.013), ethanol consumption (OR 8.61, 95% CI: 3.57–20.81; P < 0.001), CD4 cell count < 200 cells/μL (OR 13.12, 95% CI: 5.64–30.50; P < 0.001), and not on antiretroviral treatment (ART) (13.34, 95% CI: 5.85–30.41; P < 0.001) were associated with active TB. The risk factors found to be independently associated were CD4 counts < 200 cells/μL (OR 5.75, 95% CI: 1.81–18.20; P = 0003), smoking (OR 7.40, 95% CI: 1.47–37.15; P = 0.015), and not being on ART (OR 13.94, 95% CI: 3.84–50.61; P < 0.001). Conclusion: Initiating ART as soon as possible and patient education on modifiable risk factors including counseling for smoking cessation for HIV-infected individuals are warranted.

Objectives: Mycobacterium tuberculosis produces high-affinity siderophores that play essential roles in iron acquisition and tuberculosis (TB) pathogenesis. In response, host cells secrete a siderophore-binding protein, siderocalin, to limit the bacteria’s access to iron. The objective of the present study was to evaluate the levels of siderocalin in patients with TB with or without HIV infection compared to controls. Methods: Siderocalin levels were tested using a neutrophil gelatinase-associated lipocalin (NGAL) ELISA kit in four populations: HIV-infected patients with TB (HIVpos, TBpos), non-HIV-infected patients with TB (HIVneg, TBpos), HIV-infected patients without TB (HIVpos, TBneg), and healthy controls (HIVneg, TBneg). Results: Serum siderocalin levels were significantly elevated in patients with TB regardless of their HIV status (HIVneg, TBpos 920 (480–1050) pg/ml; HIVpos, TBpos 494 (166–1050) pg/ml), whereas lower levels of siderocalin were seen in HIV-positive patients (HIVpos, TBneg 268 (77–937) pg/ml; HIVneg, TBneg 453 (193–994) pg/ml). Conclusions: The results indicate that active TB leads to an up-regulation of serum siderocalin regardless of HIV status, whereas HIV infection leads to a down-regulation of serum siderocalin levels in both TB-negative and TB-positive individuals. Further studies are needed to evaluate siderocalin as a potential marker of active TB and to clarify its role in the pathogenesis of HIV-associated TB.

Axial spondyloarthropathies are characterised by bilateral sacroiliitis, asymmetric oligoarthritis, association with the human leucocyte antigen (HLA)-B27, enthesitis and dactylitis. Although IgA nephropathy has a well-documented association with seronegative spondyloarthropathies, the association with Henoch-Schonlein purpura (HSP) has been documented only in few case reports. The present case is that of a 26-year-old man who presented with fever, lower limb arthritis, abdominal pain, palpable purpura over the buttocks and lower limbs, and clinical features of sacroiliitis. His blood tests showed elevated inflammatory markers and rheumatoid factor was negative. CT scan of the sacroiliac joints confirmed sacroiliitis. Skin biopsy revealed neutrophilic small vessel vasculitis. HLA-B27 was positive in blood. A diagnosis of HSP with HLA-B27 positive axial spondyloarthritis was made. HSP can be associated with HLA-B27 positive axial spondyloarthritis and has to be considered while evaluating for causes of cutaneous small vessel vasculitis in such patients.

A 28-year-old pregnant woman in the sixth month of gestation presented with complaints of altered bowel habit for a month, on examination found to have generalised lymphadenopathy, pedal oedema and locally infiltrating ano-rectal growth. Rectal growth biopsy was reported as high-grade B-cell lymphoma. After a discussion in a multidisciplinary panel consisting of haemato-oncologists, obstetricians and physicians, she was planned to receive antenatal chemotherapy. She delivered a live baby of 1.86 kg at 36 weeks of gestational age by normal vaginal delivery. After 6 cycles of chemotherapy she had complete regression of the disease.

The diagnosis of disseminated tuberculosis (TB) in advanced HIV infection is often delayed because of difficulty in obtaining suitable specimens for culture. A total of 32 such patients from South India with positive mycobacterial blood cultures were studied over ten years. Almost all (90%) had a febrile illness and the majority (68.7%) had clinical lung involvement, but only 27.3% had positive sputum smears. Liver biopsy yielded a positive diagnosis in only 1/7. Cytopenia was almost universal (96.9%). Bone marrow cultures were, however, positive in 54.8%, of whom one-quarter grew atypical mycobacteria. Mycobacterial blood culture is therefore a useful adjunct test to diagnose TB in advanced HIV.

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.
