ABSTRACT
Procalcitonin (PCT) is one of the best validated biomarkers in the management of sepsis. However, its prognostic utility remains poorly studied. The present study sought to assess the prognostic utility of serial PCT assessments in patients with sepsis, and to compare the prognostic predictive capability of serial measurements of PCT with conventional markers of inflammation and validated intensive care unit (ICU) severity scoring systems. We recruited consecutive patients admitted to the medical units of a tertiary care center with suspected or proven bacterial infection and sepsis. Measurement of serum PCT levels, inflammatory markers, and ICU severity scores were performed at admission and repeated every 48 hours subsequently for the duration of hospital stay. 99 patients with bacterial infection and sepsis were recruited and followed until death or discharge. Median serum PCT level was similar between survivors and non-survivors on day 1, but was significantly lower at days 3, 5 and 7 in the survivors. The analysis found Acute Physiology and Chronic Health Evaluation (APACHE IV) score on all days (1, 3, 5, and 7), PCT on days 5 and 7, and Sequential Organ Failure Assessment score at 24 hours to have good predictive accuracy for adverse patient outcome. PCT clearance on days 3 and 5 of admission was measured and demonstrated predictive accuracy comparable to day-matched APACHE IV scores. While serial levels of serum PCT in patients with sepsis are accurate in the prediction of adverse patient outcome, they do not offer any additional clinical benefit over existing severity of illness scores and may be cost prohibitive in resource-limited settings. While serial levels of serum PCT in patients with sepsis are accurate in the prediction of adverse patient outcome, they do not offer any additional clinical benefit over existing severity of illness scores and may be cost prohibitive in resource-limited settings.

This study aims to evaluate the role of cardiac enzymes N-terminal pro-brain natriuretic peptide (NT-proBNP) and cardiac troponin-I (CTnI) as predictors of outcomes in patients with sepsis.78 cases with a diagnosis of sepsis were enrolled over a 2-year period. Baseline demographic, Acute Physiology and Chronic Health Evaluation-II (APACHE-II), Simplified Acute Physiology Score-II (SAPS-II), hematologic and biochemical parameters were noted. Serum NT-proBNP and CTnI were evaluated at 24 and 72 hours of admission along with echocardiography. Patients were prospectively followed up until death or discharge.Mean APACHE-II score was 19.8±9.6 and SAPS-II was 44.8±17.2. Survival rate in the study was 47.5% (36 of 78 patients). NT-proBNP was significantly higher in non-survivors with values over 4300 pg/mL at 24 hours and 5229 pg/mL at 72 hours associated with poor outcomes (p<0.05). CTnI was higher among non-survivors than in survivors, but the difference was not significant. APACHE-II score combined with NT-proBNP predicted a poor outcome in 51.2% cases compared with 14.6% cases with APACHE-II alone (p<0.05), while SAPS-II combined with NT-proBNP predicted a poor outcome in 53.6% cases as compared with 9.6% cases with SAPS-II alone (p<0.05). SAPS-II greater than 45 and NT-proBNP values at 72 hours were independent predictors of mortality in patients with sepsis.NT-proBNP is an independent predictor of mortality in patients with sepsis and its combination with APACHE-II and SAPS-II improves the predictive values of the scoring systems.

OBJECTIVE: VAP prevention bundle includes daily sedation free interval, DVT prophylaxis, raising head end of bed, use of orogastric rather than nasogastric tube. This study aims to study the practices regarding VAP prevention bundle and its compliance, educating about the practices and effects on patients outcome. DESIGN: Quasi-experimental study, conducted in 3 phases. SETTING: Hospital based. PARTICIPANTS: Invasive Mechanically ventilated patients in the Department of Medicine of a tertiary care hospital. 50 patients included in phase 1 and 3. INTERVENTION: Phase 1 and Phase 3 were pre and post intervention phases respectively when compliance to VAP prevention bundle was assessed with intermediate Phase 2, the intervention phase where the residents and nurses were educated about VAP bundle through various means. A checklist was attached to patient records. OUTCOME MEASURES: Incidence of VAP, total hospital and ICU stay, duration of mechanical ventilation and mortality. RESULTS: On comparing the 2 phases, it was found that there was increase in the compliance to VAP bundle(p<0.001), use of orogastric tube (p<0.001) and use of daily sedation free interval (p<0.001). Statistically insignificant increase in the use of DVT prophylaxis (p= 0.996) and raising the head end of the bed (p=0.513), and decline in the number of days of ICU(p=0.804) and hospital stay(p=0.907), the duration of mechanical ventilation(p=0.909), mortality(p=0.315) and incidence of VAP(p=0.715) was noted. Among those who developed VAP, there was lower compliance to bundle. CONCLUSIONS: Practices like use of VAP prevention bundle improve on teaching efforts and use of checklist which improves patient care.

BACKGROUND: Snakebite is a common but neglected public health problem of tropical & subtropical regions worldwide. This study was conducted to look into profile, first aid measures, management strategy and outcomes of snake bite patients. METHODS: This was an ambispective study conducted in the Department of Medicine & Emergency Medicine at AIIMS, New Delhi from June 2011 to May 2017 and enrolled 54 patients. In retrospective part 33 case records of snake bite patients were retrieved and in prospective part 21 patients were recruited. All relevant information including demographic parameters, first aid measures, clinical and laboratory profile and outcomes were recorded in pre made proformas. All data were analysed using IBM Stata version 13 and Microsoft Excel 2011. RESULTS: Majority of patients were male, and the mean age was 27.6 years. Maximum numbers of bites 34 (63%) happened in the rainy season and Krait was the most common culprit species. Neurological manifestations were most common (70.4%) followed by haematological. Most common complication was ventilatory failure (78.6%), and median dose of ASV was 20 vials. Forty-nine (90.7%) patients were discharged successfully. There was significant association of sepsis and shock with non survivors of snake bite with respective P values of 0.02 and 0.007. CONCLUSION: Neurotoxic snake bite (70.4%) was the most common type of envenomation. Most common complication was ventilatory failure and majority of patient (90.7%) successfully discharged. Sepsis and shock were significantly associated with non survivors of snake bite.
ABSTRACT
BACKGROUND: The prevalence of anti-retroviral therapy (ART) failure is not uniform in India. In this study we attempted to determine the prevalence and risk factors of treatment failure among patients who were on ART for >1 y. METHODS: We conducted an ambispective study from 2017 to 2019 in the All India Institute of Medical Sciences, New Delhi, India. Patients and their past medical records were examined to determine clinical, immunological and virological failure. RESULTS: Among 301 enrolled patients, the majority was male (61.8%), with a mean age of 36.98±10.84 y. The prevalence of ART failure in our study was 10.63% (32/301). Clinical, immunological and virological failure rates were 1.66%, 10.63% and 5.65%, respectively. The maximum chance of failure was the tenofovir-lamivudine-nevirapine (33.3%) regimen followed by the stavudine-lamivudine-nevirapine (30.4%) regimen. Among the nucleoside reverse transcriptase inhibitors, a stavudine-based regimen had a significantly greater chance of failure (25.8%) compared with tenofovir (9.6%) and zidovudine (7.9%) regimens (p<0.005). Low baseline CD4 count and development of tuberculosis after ART initiation were significantly (p<0.05) associated with treatment failure in univariate analysis. Patients with a low peak CD4 count (adjusted odds ratio [AOR 4.26 {95% confidence interval

Background & objectives: The models for implementation of antibiotic stewardship programme (ASP) in the acute care settings of developing countries are lacking. In most of the hospitals, patient turnover is high and a proper system for recording antibiotic-related information and tracking hospital-acquired infections is not in place. This pilot study was conducted in a tertiary care teaching hospital in north India to assess the feasibility of implementation of an ASP in a Medicine unit and to evaluate the effect of implementation as per the criteria applicable in this set up. Methods: A pre-post-quasi-experimental non-randomized study was conducted in two phases. In the first phase, current practices in the Medicine wards were observed. In the second phase, the ASP was implemented in a single Medicine unit, along with prospective audit and feedback, tracking of the process, as well as outcome measures. Patient risk stratification, blood culture on day one, day 3 bundle, dose optimization, de-escalation and intravenous to oral conversion of antibiotics were the key elements focused upon. Results: There was a significant improvement in the appropriateness of antibiotic prescription (66 vs. 86%, P<0.001) and reduction in the mean number of antibiotics used per person (4.41 vs. 3.86, P<0.05) along with decrease in the duration of hospital stay (17 vs. 14 days, P<0.05). There was a significant improvement in sending of blood cultures on day one during the stewardship phase (P<0.001). Interpretation & conclusions: The ASP approach used in our pilot study may be feasible and beneficial. However, it needs further confirmation in other settings and on a large scale.

Scrub typhus is largely ignored in India particularly during outbreaks of viral fever. The disease course is often complicated leading to fatalities in the absence of treatment. However, if diagnosed early and a specific treatment is initiated, the cure rate is high. We report here five cases of scrub typhus to highlight the fact that high clinical suspicion for such a deadly disease is an absolute necessity.

With significant advancement in the tools and strategies available for diagnosis and management, there is an expected change in the epidemiological profile of patients living with HIV/AIDS (Human immunodeficiency syndrome/Acquired immunedeficiency syndrome). We retrospectively analyzed the changing epidemiological pattern of HIV infection over a period of 13 years in the anti-retroviral (ART) center of a tertiary care hospital in India. The study included a total of 9419 patients (8811 adults and 608 children) who were registered at our ART center between 2005 and 2017. Among adult patients, 68.9% patients were males and the mean age of presentation was 35.6±9.9 years. Heterosexual route was the most common route of transmission (95.5%). A total of 97.4% of pediatric patients acquired HIV infection via vertical transmission from their mothers. Most of the adult patients (77.1%) were educated only to primary level. Despite the economic growth in the country over the years, the monthly income of these patients has not significantly changed. The median CD4 count at the time of eligibility for starting ART was 244/µl of blood. An increasing trend in the baseline CD4 count was noticed from 2005 to 2017. Also, improved outcomes with less loss to follow up were noticed in the latter years. However, an increasing trend was also noted in the time gap between registration at the ART center and initiation of ART. Improvement in the baseline CD4 count and better treatment outcomes are indicators of a well-functioning national program. However, continued programmatic interventions are needed to further tackle the menace of HIV/AIDS in India.

Allergic bronchopulmonary aspergillosis (ABPA) is an immunologically mediated disease characterized by a hypersensitivity reaction to fungal colonization by Aspergillus. Hydropneumothoraces and bronchopleural fistulae are rare occurrences in patients with ABPA. However, the diagnosis of ABPA is important to consider, as it is easily treatable with specific therapy. We report an unusual case of a patient with ABPA who presented to us with hydropneumothorax with bronchopleural fistula.
ABSTRACT
A 21-year old female, recently diagnosed with osteosarcoma of right humerus, presented to the emergency with history of fever, productive cough, chest pain and progressive respiratory distress for six days. Initial investigations suggested pneumonia but she did not respond to parenteral antibiotics. CT pulmonary angiogram revealed bilateral pulmonary artery embolism. Thrombolysis was performed using alteplase, which failed to improve the clinical condition. In view of underlying malignancy, a possibility of tumour-embolism was considered and she was started on chemotherapy for osteosarcoma. There was dramatic improvement in her respiratory symptoms after the first chemotherapy cycle, along with radiological resolution of the embolism. This case highlights the importance of suspecting tumour embolism in a known case of malignancy with respiratory distress.

Acute febrile illness (AFI) is one of the commonest indications for hospitalization and can present with varying severity including single or multiple organ dysfunction syndrome (MODS). During monsoon season, there is a spurt of AFI often caused by vector borne diseases leading to substantial morbidity and mortality. Our aim was to determine distribution of etiological causes, differential organ involvement and predictors of mortality in critically ill patients with AFI. It was a hospital based observational study which included patients with AFI with dysfunction of at least one organ system. The study was conducted over 4 months during monsoon season. Admitted patients were included who had been subjected to a standard battery of tests and managed with standard hospital based management protocol. 145 patients were included and etiology of fever was ascertained in 81.4% of patients with the most common single infection being chikungunya (20.7%) followed by dengue (20%) fever. Thrombocytopenia and deranged liver biochemistry each were seen in nearly 75% of the patients. Renal (50.3%) and nervous system (46.2%) dysfunction were the predominant organ failures. 49 patients died (33.8%) which correlated with predicted mortality by APACHE (acute physiological assessment and chronic health evaluation) II score. Independent predictors for mortality were older age (> 55 years) (p = 0.01), acidemia (p = 0.01), altered sensorium (p = 0.02) and coagulopathy (p = 0.048). Sub-group analysis revealed that amongst patients with MODS, hypotension could help differentiate between bacterial and non-bacterial causes (p = 0.01). Critically ill patients with AFI suffer from significant morbidity and mortality. Features like the presence of hypotension in MODS may differentiate between a bacterial cause vis-à-vis viral or protozoal etiology.

OBJECTIVE: Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is an aggressive extranodal lymphoma of NK-cell or T-cell lineage. Its clinical features overlap with those of several sinonasal mass lesions. While the histopathological features are well described, diagnosis is often difficult, owing to presence of extensive coagulative necrosis, so that repeated biopsies may sometimes be necessary for correct diagnosis. Literature on cytological findings of ENKTL is limited. METHODS: Cytomorphological features of cases of histologically confirmed ENKTL having corresponding cytology samples were reviewed retrospectively, to identify distinctive features that could possibly suggest this entity. RESULTS: Aspirates from five patients were studied: four from cervical nodes, one from cheek swelling and one from pleural fluid. Two aspirates were reported as positive for malignancy, two as atypical lymphoid proliferation and one was non-diagnostic. Pleural fluid was reported as malignant, favouring a diagnosis of carcinoma. On cytology, aspirates showed medium to large cells with folded, indented nuclei and abundant pale cytoplasm, some with tongue-like cytoplasmic protrusions. A distinctive feature was presence of large loose clusters of tumour cells with arborising capillaries running through them. Interestingly, necrosis was consistently absent. Subsequent biopsies from palate (three cases) and nasal masses (two cases) confirmed the diagnosis of ENKTL. CONCLUSIONS: Suspicion of ENKTL on cytology is crucial for timely diagnosis to avoid diagnostic delay, especially when only highly necrotic biopsy samples are available. Awareness of distinctive cytomorphological features is required to make fine needle aspiration an effective diagnostic tool for initial diagnosis and for evaluation of possible recurrences.

Aim: To evaluate patterns of retinal vasculitis with ultra-wide field imaging (UWF) and ascertain the risk factors for retinal neovascularization. Methods: Consecutive patients of retinal vasculitis were included prospectively. Patients with retinal vasculitis secondary to uveitis were excluded. UWF was done for all the patients. Retinal involvement was classified into three zones and area of capillary non-perfusion was stratified into clock hours. Results: Two hundred patients were included, 85% (n = 170) were male. Mean age was 28.99 ± 10.56 years. Clinical examination revealed 65% cases (n = 130) to be bilateral, while UWF angiography detected 72.5% (n = 145) to have bilateral involvement. Retinal neovascularization was present in 47% (n = 188).Presence of posterior disease had very high odds ratio for development of retinal neovascularization as compared to cases restricted to retinal periphery (OR = 45.03, CI = 6.10-332.30, p = < 0.001). Conclusion: UWF imaging is useful in detecting retinal vasculitis, which is otherwise obscure to clinical examination and assessing risk factors for retinal neovascularization.

Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are the backbone of effective anti-retroviral therapy in the developing world. Efavirenz is the current NNRTI of choice due to reports of higher incidence of serious adverse events with nevirapine. Majority of patients with Human immunodeficiency virus (HIV) infection in India are still on nevirapine based therapy. The aim of the study was to evaluate the need of shifting these patients to efavirenz based therapy. A cross-sectional study was conducted on adult patients, who were on NNRTI based regimen for more than one year with good adherence. The patients were divided into efavirenz or nevirapine groups based on the treatments they were receiving at the time of study. The different arms were compared based on their clinical and laboratory profile, adverse events and immunological response. A total of 244 patients were recruited. A total of 125 patients were receiving nevirapine based regimen while 119 patients were receiving efavirenz based regimen. There was no significant difference in the frequency of hematological and biochemical derangements between the two groups. There was no difference in the median highest CD4 count achieved during therapy between the two groups. Clinically observed side effects were more common in the efavirenz group. These results suggest that there isn't enough evidence to shift patients tolerating long term nevirapine based therapy to efavirenz based therapy.

A 56 year old lady, presented to our institute with six months history of low grade fever, generalized weakness, decreased food intake and fluctuating sensorium. Initial investigations revealed hypercalcemia, renal dysfunction and anemia. Initial working diagnosis of likely underlying hematological malignancy such as lymphoma or multiple myeloma (MM) was kept after hyperparathyroidism was ruled out. Her skeletal survey revealed lytic lesions in the skull, bone marrow aspirate showed 12% plasma cells and beta-two microglobulin level was markedly elevated. However, the criterion for MM was not fully satisfied. In view of persistent altered sensorium, MRI brain was done which suggested the diagnosis of disseminated tuberculosis and was further confirmed through MR spectroscopy, bone marrow biopsy (showing granulomas) and whole body PET. She was started on anti-tubercular therapy along with steroids with marked response within a week. We describe the details of this interesting case through a systematic approach to the various features.

Histoplasmosis is a systemic fungal infection caused by Histoplasma capsulatum which occurs endemically in some parts of the world like North and Central America particularly in Mississippi and Ohio River valleys, but is uncommon in India. Progressive disseminated form of histoplasmosis (PDH) usually occurs in the immune-compromised hosts especially in HIV positive population. In PDH any organ can be involved like lung, liver, spleen, brain, adrenals etc. Involvement of oral cavity and buccal mucosa in PDH is common but pharyngeal involvement is rare. We here report a case of progressive disseminated histoplasmsosis with pharyngeal involvement in an immunocompetent male from non-endemic area. This case presented to us with history of long duration fever and we found the etiology by giving due significance to a trivial symptom and thorough evaluation of the same. Etiology was found as disseminated histoplasmosis, which is not a common disease. We treated him initially with amphotericin-B then subsequently with itraconazole for one year. He recovered fully over the period of one year with the given treatment. This case report emphasizes that disseminated histoplasmosis should be considered one differential diagnosis in case of long duration of fever, even in an immunocompetent patient. It also emphasizes that in evaluation of a case of long duration of fever, even a trivial symptom is very crucial, which may direct towards the diagnosis.
ABSTRACT
OBJECTIVE: Dengue infection is a rapidly spreading vector-borne disease and is endemic in the Indian subcontinent. It has varied manifestations ranging from subclinical infection to severe fatal shock syndrome. This study aimed to estimate cytokine level in dengue patients and correlate them with dengue severity. METHODS: Cases of dengue fever diagnosed in the department of medicine of our institute from July 2015 to November 2016 were included in the study. The clinical features, biochemical, hematological and radiological parameters along with cytokine levels (Interferon-gamma, Interleukin-6, and Tumour Necrosis Factor-alpha) were recorded in all patients. RESULTS: Out of 80 confirmed cases of dengue included in the study, 50 had nonsevere dengue (Group 1), and 30 patients had severe dengue (Group 2). The median level of serum TNF-α in group 2 (62.5 pg/mL) was significantly higher than the median level in group 1 (20 pg/mL), (p=0.043). Similarly, the median level of serum IFN-γ in group 2 (10.25 pg/mL) was significantly higher than the median level in group 1 (8.5 pg/mL), (p=0.002). The median level of IL-6 was also higher in group 2 (29 pg/ml) as compared group 1(14.2 pg/ml), but this result was not significant (p>0.05). CONCLUSION: Some cytokines may play a role in the pathogenesis of severe manifestations of dengue.
ABSTRACT
Septic pulmonary emboli can occur as a complication of many diseases, most common being right sided infective endocarditis. Septic emboli through a peripheral venous cannula are rarely reported in literature though central venous catheter is commonly implicated. We describe a case of widespread cellulitis and septic pulmonary emboli as a complication of peripheral venous cannulation.
