ISCCM Position Statement: Management of Severe Dengue in Intensive Care Unit.

Dengue is one of the commonest causes of undifferentiated acute febrile illness in India as well as South East Asia. Nearly two-fifths of the world population is at risk of infection, and nearly 96 million infections reported worldwide, it is a major cause of concern across the globe. The ISCCM leadership felt that there have been no new directives/guidelines except the MOH guidelines for the management of dengue fever since 2014. Under the auspices of the Indian Society of Critical Care Medicine (ISCCM), an expert group of 14 intensivists from across the country, was formed. The task force members formulated questions that needed to be answered. These questions were validated by the members of ISCCM attending research conclave 2023. All the members systematically searched PubMed, MEDLINE, and Science Direct for original articles on different aspects of dengue management between January 1, 2000, and July 1, 2023. From the collected articles, duplicates were removed. Based on the evidence collected, the expert group members prepared statements/answers to the questions. Since most of the evidence is of moderate to low quality, a consensus was generated amongst the members of the task force. Each statement was agreed upon by 70% of the task force. The statements presented in the article are consensus statements as answers to queries raised. How to cite this article: Bhalla A, Singh H, Suri V, Yaddanapudi L, Poddar B, Ghawat R, et al.

Exploring the therapeutic and prophylactic potential of bedaquiline in leprosy.

Leprosy remains a significant public health concern despite major strides in treatment and control efforts. The Global Leprosy Strategy 2021-2030 and the National Strategic Plan for Leprosy 2023-2027 majorly focus on facilitating action to reach the goal of zero leprosy. Exploration of new treatment regimens is emphasized as one of the verticals of the multipronged approach for reaching the aforementioned goals. This becomes particularly pertinent in the wake of growing evidence for resistance to the drugs currently being used in the management of leprosy. Repurposed molecules present a very good approach in this direction. The present review aims to explore the potential of bedaquiline, a drug used for multidrug-resistant tuberculosis, as a potential addition to the therapeutic armamentarium of leprosy. Through this narrative review, the authors attempt to look into the available proof of concept, clinical evidence, potential risks, and possible ways forward with bedaquiline in leprosy.

A multicentre, double-blind, placebo-controlled randomized trial of Mycobacterium w in critically ill patients with COVID-19 (ARMY-2).

BACKGROUND: Mycobacterium w (Mw), an immunomodulator, resulted in better clinical status in severe coronavirus infectious disease 19 (COVID-19) but no survival benefit in a previous study. Herein, we investigate whether Mw could improve clinical outcomes and survival in COVID-19. MATERIALS AND METHODS: In a multicentric, randomized, double-blind, parallel-group, placebo-controlled trial, we randomized hospitalized subjects with severe COVID-19 to receive either 0.3 mL/day of Mw intradermally or a matching placebo for three consecutive days. The primary outcome was 28-day mortality. The co-primary outcome was the distribution of clinical status assessed on a seven-point ordinal scale ranging from discharged (category 1) to death (category 7) on study days 14, 21, and 28. The key secondary outcomes were the change in sequential organ failure assessment (SOFA) score on days 7 and 14 compared to the baseline, treatment-emergent adverse events, and others. RESULTS: We included 273 subjects (136 Mw, 137 placebo). The use of Mw did not improve 28-day survival (Mw vs. placebo, 18 [13.2%] vs. 12 [8.8%], P = 0.259) or the clinical status on days 14 (odds ratio [OR], 1.33; 95% confidence intervals [CI], 0.79-2.3), 21 (OR, 1.49; 95% CI, 0.83-2.7) or 28 (OR, 1.49; 95% CI, 0.79-2.8) between the two study arms. There was no difference in the delta SOFA score or other secondary outcomes between the two groups. We observed higher injection site reactions with Mw. CONCLUSION: Mw did not reduce 28-day mortality or improve clinical status on days 14, 21 and 28 compared to placebo in patients with severe COVID-19. [Trial identifier: CTRI/2020/04/024846].

A case series of post-infectious chikungunya myeloradiculoneuropathy.

Chikungunya fever is an arboviral illness caused by chikungunya virus (CHIKV) and transmitted by the bite of Aedes aegypti and Aedes albopictus. It is an RNA virus belonging to the genus Alphavirus and family Togaviridae. We present a case series of three patients with chikungunya illness developing para/post-infectious myeloradiculoneuropathy.These patients developed neurological symptoms in the form of bilateral lower limb weakness with sensory and bowel involvement after the recovery from the initial acute episode of chikungunya fever. Clinical examination findings suggested myeloradiculoneuropathy with normal Magnetic Resonance Imaging of the Spine, with the nerve conduction study showing sensorimotor axonal polyneuropathy. All the patients were treated with 1 g of methylprednisolone once a day for five days, and case 2 was given intravenous immunoglobulin also. In the follow-up, cases 1 and 2 showed complete recovery without recurrence, and case 3 did not show improvement at one month.

To Study the Distress, Anxiety, Depression, and Sleep Effects of the COVID-19 Pandemic on Essential Workers.

Essential care workers like police personnel, social workers, and office and administrative staff of health institutions are also at increased risk of coronavirus disease 2019 (COVID-19) exposure along with healthcare workers. The present study aims to estimate the distress, anxiety, depression, and sleep impact of COVID-19 pandemic on essential workers through an online survey. This cross-sectional study (included 369 participants) was conducted in Chandigarh through an online survey using three psychological scales: Peritraumatic Distress Inventory (PDI), Insomnia Severity Index, and Depression Anxiety Stress Scale. Three-hundred-sixty-nine frontline warriors from hospital and community settings were included in the study. The respondents include police personnel (274; 73.66%), office staff (24; 6.45%), social workers (53; 14.24%), and media staff (21; 5.65%). Maximum distress was reported by media/transport officials on duty (85.7%). The majority of them scored high (>14), and slightly less than one-fourth (23.8%) scored significantly abnormal (>23) on PDI. About 42.9% reported moderate insomnia, 52.4% exhibited severe anxiety, and 33.3% of media/transport participants reported severe depression. Psychological morbidity is high in media/transport and social workers working in the community during the COVID-19 pandemic.

A Study of Hypertension and Related Biophysical and Health-related Lifestyle Behaviors in Patients Suffering from Schizophrenia.

Background: Schizophrenia is a life-shortening disease. The standardized mortality ratio has been higher than that of the general population, and it has doubled what it was 3-4 decades ago. This rise is mostly attributed to the increased cardiovascular risk associated with high second-generation antipsychotic (SGA) use. Evidence from the first-generation antipsychotic (FGA) era shows a lower prevalence of hypertension (HTN) but data regarding SGAs is scarce. Purpose: The purpose of the study was to assess the prevalence of HTN and related factors using standardized methodology in patients with schizophrenia on treatment with SGAs. Methods: A cross-sectional study through convenient sampling was done. Blood pressure, anthropometry, physical activity, and health-related lifestyle factors were assessed using the standard World Health Organization (WHO) methodology of cardiovascular survey methods and the Global Physical Activity Questionnaire (GPAQ) version 2. The prevalence of HTN, obesity, inadequate physical activity, and other demographic and clinical correlates like antipsychotic use, duration of illness, and family history of non-communicable diseases (NCDs) were studied. Results: The prevalence of HTN is 20.50%, and it increases with age. SGAs with the use of a single agent are the most common. In total, 45.50% of persons with schizophrenia have a positive family history of a NCD; 22.00% and 07.50% are current tobacco and alcohol users, respectively; and 70% have abdominal obesity, and 54% have generalized obesity. Waist circumference, obesity, and family history of NCDs are significant correlates of HTN. A family history of NCDs is the most significant predictor. Conclusion: The prevalence of HTN is lower than that of the general population despite the high prevalence of SGA use, obesity, and inadequate physical activity.

Knuckle hyperpigmentation in a young male: A clinical sign of B12 deficiency not to be missed.

Vitamin B12 and folate deficiency are reversible causes of megaloblastic anemia. Strict vegetarians are at risk of megaloblastic anemia due to low cobalamin in their diet. Knuckle hyperpigmentation in patients with megaloblastic anemia is due to excess melanin synthesis in skin. Here we present a case of a young vegetarian male with megaloblastic anemia with knuckle hyperpigmentation managed successfully with intravenous followed by oral vitamin b12 and folate supplementation.

Rapid Decline of SARS-CoV-2 Viral Load in Single vs. Double-Dose (Short-Interval <6 Weeks) ChAdOx nCoV-19 Vaccinated Health-Care Workers.

The present work was carried out during the emergence of Delta Variant of Concern (VoC) and aimed to study the change in SARS CoV-2 viral load in Covishield vaccinated asymptomatic/mildly symptomatic health-care workers (HCWs) to find out the optimum isolation period. The SARS CoV-2 viral load was carried out in sequential samples of 55 eligible HCWs which included unvaccinated (UnV; n = 11), single-dose vaccinated (SDV, n = 20) and double-dose vaccinated [DDV, n = 24; short-interval (<6 weeks)] subjects. The mean load of envelope (E) gene on day 5 in SDV [0.42 × 105 copies/reaction] was significantly lower as compared to DDV [6.3 × 105 copies/reaction, P = 0.005] and UnV [6.6 × 105 copies/reaction, P = 0.001] groups. The rate of decline of SARS CoV-2 viral load in the initial 5 days of PCR positivity was significantly higher in SDV as compared to that in DDV (Mean log decline 0.39 vs. 0.19; P < 0.001). This was possibly due to interference of adenoviral immunity of first dose of adenovirus-vectored vaccine in double-dose vaccinated HCWs who had received vaccines within a shorter interval (<6 weeks).

Cycle threshold values of SARS-CoV-2 RNA in conjunctival swabs and nasopharyngeal secretions: a comparative study from a tertiary care center in India.

PURPOSE: To detect the viral RNA load of SARS-CoV-2 in conjunctival swabs of COVID-19 patients, and compare with nasopharyngeal swabs. METHODS: Conjunctival swabs of COVID-19 patients (with PCR positive nasopharyngeal swabs) were subjected to quantitative reverse transcription-polymerase chain reaction (RT-PCR) for detection of SARS-CoV-2 RNA. The cycle threshold (Ct) values of Open Reading Frame 1 (ORF 1 Ab gene) and nucleoprotein (N gene) PCRs were used to assess the viral RNA load, and compare them with the baseline values of nasopharyngeal swabs. RESULTS: Of 93 patients, 17 (18.27%) demonstrated SARS-CoV-2 RNA in conjunctival swabs. Baseline nasopharyngeal swabs were collected at a median of 2 days; while, the conjunctival swabs were collected at median 7 days, from onset of illness (p < 0.001). Despite a significant delay in conjunctival swab collection than nasopharyngeal swabs, the Ct values (ORF or N gene PCRs) were comparable between nasopharyngeal swab and conjunctival swab samples. Subsequently, during the recovery period, in four of these 17 patients (with conjunctival swab positivity), when the second nasopharyngeal swab was 'negative', the conjunctival swab was 'positive'. CONCLUSION: The conjunctival swabs demonstrated SARS-CoV-2 RNA in 17 (18.27%) of 93 COVID-19 patients. Our results may suggest a delayed or a prolonged shedding of the virus/viral RNA on the ocular surface than in nasopharyngeal mucosa.

Case Report: A Case of Complicated Typhoid Fever with Rhabdomyolysis and Hemophagocytic Lymphohistiocytosis.

Typhoid fever can have diverse extra-intestinal complications including encephalitis, Guillain-Barré syndrome, endocarditis, myocarditis, osteomyelitis, renal abscess, and splenic abscesses. Secondary hemophagocytic lymphohistiocytosis with rhabdomyolysis is a rare complication of typhoid fever. Here, we present the case of an adolescent with typhoid fever complicated by rhabdomyolysis and hemophagocytic lymphohistiocytosis.

The continuum of liver injury with severity of dengue fever: A retrospective observational study.

BACKGROUND: Dengue is a major international health concern prevalent in tropical and sub-tropical countries. There are a paucity of studies on the relationship of hepatic complications with inflammatory parameters in dengue infection. METHODS: Single-centre observational study was conducted at the tertiary care centre in North India. Patients (>12 years) diagnosed with dengue infection between August and November 2021 were enrolled in the study. The frequency of hepatic derangements and their associations with inflammatory severity was analysed. RESULTS: Based on the clinical symptoms, 170 patients were classified into three categories, namely, dengue fever, warning dengue and severe dengue. Higher incidence of liver dysfunction was observed in severe dengue patients with median values of aspartate aminotransferase (AST) (3051 U/L, p < 0.001), alanine aminotransferase (ALT) (1792 U/L, p = 0.009), alkaline phosphatase (172 U/L, p = 0.001), T.Bil (34.2 µmol/L, p < 0.001), albumin (30 g/L, <0.001), and gamma-glutamyl transferase (152 U/L, p < 0.001) along with inflammatory marker C-reactive protein (CRP) (43 mg/dL, p < 0.001) highly deranged, in comparison to patients with/without warning signs. Median levels of CRP were found to be positively and significantly correlated with the median levels of AST and ALT (p < 0.05, r = 0.99) in all three categories of dengue patients. Liver injury was noted in 107 (63%) of the cohort, and mixed type of liver injury involving both hepatocellular and cholestatic patterns was observed as the most common type of injury (n = 50, 29.4%). Liver injury correlated with the severity of dengue illness as about 85% of severe dengue patients had significant liver injury (p = 0.014). CONCLUSION: In dengue patients, the association of the liver injury with inflammatory severity suggests that the mechanism of liver injury may be related to inflammatory response apart from the hepatotropic nature of the virus.

An Unusual Case of Post-partum Native Tricuspid Valve Infective Endocarditis.

Native valve infective endocarditis during pregnancy or the peripartum period is a rare entity with significant morbidity and mortality. Rheumatic heart disease was previously considered a significant risk factor, changing to intravenous drug abuse in recent decades. We hereby report a case of tricuspid native valve endocarditis complicating the peri-partum period in a young female without underlying traditional risk factors, who improved with medical therapy alone.

A Case Series of Scrub Meningoencephalitis from a Tertiary Care Center in North India.

Scrub typhus infection is reemerging leading cause of acute febrile illnesses in post-rainy or monsoon season in Southeast Asia. It is caused by Orientia tsutsugamushi and spread by the bite of chiggers, larval forms of trombiculid mites. The clinical picture can range from simple acute febrile illness to multiorgan dysfunction. Neurological manifestations also vary from aseptic meningitis, meningoencephalitis, cerebral infarction, acute disseminated encephalomyelitis, transverse myelitis, and psychiatric manifestations. Here, we present a case series of eight cases of scrub meningoencephalitis diagnosed based on clinical, laboratory, and radiological criteria.
