Retrospective analysis of IgG4-related disease cases at a tertiary care centre in India.

Objectives: IgG4-related disease (IgG4-RD) is a chronic inflammatory disorder with prominent fibrosis. This retrospective analysis was undertaken to study the clinical, laboratory, and radiological characteristics of patients with extra-pancreatic IgG4-RD and their response to treatment at a tertiary care centre located in northern India. Material and methods: Patient data from our centre between January 2017 and January 2021 were reviewed. Probable/definite IgG4-RD cases were included in the analysis. Results: A total of 14 cases were identified with a median age of 39 years (range 19-56 years). There were 10 males and 4 females. All patients presented with slowly progressive soft tissue swellings with pain/discomfort related to local mass effect. The median delay in diagnosis was 9.5 months (range 2-72 months). Cross-sectional imaging showed soft tissue masses in all cases. All contrast-enhanced studies (n = 7) showed enhancement on computed tomography and magnetic resonance imaging scan. F-18 fluorodeoxyglucose-avidity was observed in 8 of 9 (88.9%) cases. Biopsies performed in 12 of these were classified as definite in 8 and possible IgG4-RD in 4 cases. Patients were treated with a median dose of 1 mg/kg/day (range 0.5-1 mg/kg/day) prednisolone. Steroids were successfully tapered in all 12 cases with 41.6% (5 of 12) being off corticosteroids at a median follow-up of 10 months (range 0-18 months). Two patients were lost to follow-up. Conclusions: IgG4-related disease is a chronic illness with a wide spectrum of manifestations, in which the diagnosis is often delayed, but it shows an excellent response to treatment. Efforts must be made to increase awareness among physicians about this disease to institute appropriate treatment as early as possible.

Management of dengue with co-infections: an updated narrative review.

Dengue is a life-threatening mosquito borne viral disease. We are still in the era of supportive treatment where morbidity and mortality are a major concern. Dengue infection in presence of other co-infections makes this scenario rather worse. Timely recognition and raising alarm to be intensive is the need of the hour for primary care physicians practicing in the community and indoors. This review provides a comprehensive knowledge about the recent trends of coinfection in dengue as well as their management consideration which will be particularly helpful for physicians practicing in rural and remote areas of India.

Infective Endocarditis Following Chicken Pox: A Rare Association.

A 38-year old immunocompetent male presented to us with chicken pox complicated by development of Guillain-Barre syndrome (GBS) and left-sided native valve endocarditis due to methicillin resistant Staphylococcus aureus (MRSA). This was further complicated by embolization to various vital organs including the brain. The patient was treated with vancomycin for four weeks but did not respond to the treatment. We present this case to highlight the rare complications associated with chicken pox and the challenges faced in management of such a case.

Approach to acute febrile illness during the COVID-19 pandemic.

Coronavirus disease 2019 (COVID-19) is a febrile respiratory illness that has spread rampantly across the globe and has emerged as one of the biggest pandemics of all time. Besides the direct effects of COVID-19 on mortality, collateral impacts on diagnosis and management of acute febrile illnesses (AFI) is a matter of great concern. The overlap in presentation, shunting of available resources and infection control precautions in patients with suspected COVID-19 result in a significant delay in diagnoses and management of AFI. This review highlights the challenges in the management of acute febrile illness during COVID pandemic and possible solutions for the same.

COVID-19 in patients living with human immunodeficiency virus (HIV) infection: Challenges and way-forward.

Most studies have described worse outcomes with coronavirus disease 2019 (COVID-19) in patients with human immunodeficiency virus (HIV). This has been attributed to COVID-19 associated lymphopenia (resulting in lower CD4 count), higher prevalence of comorbidities (established risk factors for severity in COVID-19) and pre-existing lung damage. The problem has been further aggravated by the lack in the access to routine care in HIV patients due to diversion of resources. In this article, we discuss the impact of COVID-19 on patients with HIV infection.

Serum Angiopoietin-1 and -2 and VEGF are associated with severe disease in vivax malaria.

BACKGROUND & OBJECTIVES: Malaria continues to be a significant public health problem in tropical countries including India; however, there are limited tools to predict occurrence of severe disease due to malaria. This study was designed to evaluate the role of Angiopoietin-1 (Ang-1), Angiopoietin-2 (Ang-2), Vascular endothelial growth factor (VEGF) and Asymmetric Dimethylarginine (ADMA)as disease biomarkers in uncomplicated malaria (UM) and severe malaria (SM). METHODS: This is a prospective observational study carried out at All India Institute of Medical Sciences (AIIMS), tertiary referral hospital in New Delhi, India. The study population included patients diagnosed with malaria (Plasmodium falciparum or Plasmodium vivax) either by rapid diagnostic kit test or positive peripheral smear and age more than 12 years. Forty-nine patients (25 with SM, 24 with UM) and 22 controls were recruited. In addition to routine investigations, serum concentrations of Ang-1, Ang-2, VEGF and ADMA were measured using ELISA technique. RESULTS: We observed Ang-1 serum levels to be significantly lower in patients with severe malaria (7775 pg/ml) compared to uncomplicated malaria (17629 pg/ml) and healthy controls (43472 pg/ml) [p <0.001]. Ang-2 levels were significantly higher in severe malaria (11100 pg/ml) compared to uncomplicated malaria (7315 pg/ml) and healthy controls (3679 pg/ml) (p <0.001). The ratio of Ang-2/Ang-1 was significantly higher in patients with severe malaria. VEGF serum levels was significantly lower in severe malaria (130.36 pg/ml) compared to uncomplicated malaria (317.3 pg/ml). The Ang-1, Ang-2 and VEGF levels were able to differentiate severe malaria from uncomplicated malaria caused by P. vivax but not with P. falciparum. INTERPRETATION & CONCLUSION: We conclude that Ang-1, Ang-2 and VEGF are markers of disease severity in vivax malaria.

Bedside sonography by medicine residents in critically Ill patients: A retrospective study from a teaching hospital in India.

CONTEXT: Ultrasonography has become the frontline diagnostic tool for emergency care because of its non-invasive nature and the feasibility to perform repeated quick assessments in sick patients. The effectiveness of this modality, when used by trainee doctors to take clinically important decisions in patients requiring emergency care, is not much explored. In this pilot study, we analyzed whether use of this technology by Medicine resident doctors can help in better decision making in acutely and critical ill patients. SETTING AND DESIGN: This is a retrospective study conducted in the Department of Medicine, All India Institute of Medical Sciences, New Delhi. METHODS AND MATERIALS: The study was conducted using patient data collected from acutely ill and critical care patients, who underwent bedside ultrasonography from August 2017 to August 2018. In all cases, resident doctor's finding had been assessed by an experienced operator before a treatment decision was made. STATISTICAL ANALYSIS USED: Continuous variables with normal distribution were computed using t test. Ordinal variables and variables following non-normal distribution were analyzed using the Wilcoxon rank-sum test. RESULTS: Thirty-two patients were recruited. There was agreement on 78% (25/32) ultrasound records between the trainee and the experienced operator. Among patients evaluated for shock, agreement reached 83% (15/18). Among patients who underwent transthoracic echocardiography, agreement was 66.7% (4/6). Among patients who underwent lung ultrasound, agreement was 70% (7/10). In both the patients in whom abdominal ultrasound was done, final inferences were consistent between the residents and experts. CONCLUSIONS: The results show that in majority of critically ill patients, Medicine residents made sonographic observations correctly and took clinically precise sonography guided decisions on par with expert sonologists even with minimal training and ultrasound exposure.

Curious case of fever of unknown origin.

A 58-year-old immunocompetent woman presented with fever and significant weight loss of 4-month duration. She had mild pallor; rest of the examination was unremarkable. Investigations revealed anaemia with raised inflammatory markers. Cultures, serologies, routine urine examination, bone marrow examination, contrast enhanced CT and two-dimensional echocardiography examination were unremarkable. An 18F-fluorodeoxyglucose positron emission tomography with CT (18F-FDG-PET/CT) scan was performed which revealed atypical heterogenous uptake in bilateral renal cortex. Subsequently, urine GeneXpert came positive for Mycobacterium tuberculosis with sensitivity to rifampicin. She responded to category 1 antitubercular therapy. The challenges in diagnosis of genitourinary tuberculosis, low sensitivity of conventional diagnostic tests and potential role of GeneXpert and 18F-FDG-PET/CT scan are discussed in this report.

An Unusual Sequelae of Uncomplicated Vivax Malaria.

Albeit malaria is a common health problem in many parts of the world, the entity of post-malaria neurological syndrome (PMNS) is not well recognized. This is a rare entity of neurological and psychiatric manifestations described in patients with falciparum malaria which usually develops within 2 months of recovery from the illness. It has been reported in 1.2/1000 falciparum malaria cases, more commonly in those with severe disease. We report case of a 62-yrs-old male presenting with recurrent generalized seizures following adequately treated vivax malaria. Relevant investigations were done to rule out other differentials. The patient recovered completely reiterating the self-limiting course of PMNS. Occurrence of PMNS following uncomplicated vivax malaria is peculiar in this report.

Uncommon manifestation of leptospirosis: a diagnostic challenge.

Leptospirosis is a zoonotic disease commonly affecting the tropical countries. It may have protean clinical manifestations including hepatorenal dysfunction, myocarditis, pulmonary haemorrhage, meningitis, optic neuritis and rhabdomyolysis. Neurological manifestation of leptospirosis without the classical hepatorenal dysfunction is a rare entity. This complication of leptospirosis can present with diverse central and peripheral neurological presentations. The overlapping clinical manifestations with many common tropical pathogens often pose diagnostic dilemma and delay in definitive therapy may lead to adverse clinical consequences. We report a case of a 19-year-old man with no prior comorbidities presenting with high-grade fever and altered sensorium. He was diagnosed to be a probable case of leptospirosis, based on all available test results and by fulfilment of parameters under modified Faine's criteria. The patient was successfully managed and discharged in stable condition.

Recurrent chylous effusions and venous thrombosis: Uncommon presentation of a common condition.

Spontaneous bilateral chylothorax and chylous ascites rarely develop in conjunction with systemic venous thrombosis, and the most common cause of non-traumatic chylous effusion is a malignancy. A 23-year-old immunocompetent female presented with a fever of 5 months' duration associated with progressive shortness of breath and abdominal distension. Evaluation revealed bilateral chylothorax, chylous ascites, and multiple venous thrombosis. Anti-tubercular drugs were initiated on the basis of a lymph node biopsy and computed tomography findings, but her symptoms worsened, and she developed massive bilateral pleural effusions with type 2 respiratory failure requiring invasive mechanical ventilation. She was managed with anti-tubercular drugs, chest tube drainage, octreotide, anticoagulants, and other supportive treatments. A multipronged approach to the management of chylous effusions and addition of octreotide led to resolution of symptoms. The challenges faced in diagnosing and managing this case are discussed in this report.

Two cases of Osteoarticular Mucor menace: A diagnostic and management conundrum.

Mucormycosis is an uncommon aggressive fungal infection usually seen in immunocompromised hosts or patients with burns and trauma. The common presentations include rhino-orbital-cerebral and pulmonary involvement. Osteoarticular involvement is a rare presentation of this disease. We present two cases of osteoarticular mucormycosis of pelvis and long bones of the lower limb, one in a patient with burn injury and other one in a patient with chronic granulomatous disease, hitherto a rarely reported association. Delayed diagnosis in a setting where tuberculosis is a common cause of chronic osteomyelitis, challenges in medical and surgical management of these patients are discussed in this report.

Invasive fungal infections in critically ill patients: A prospective study from a tertiary care hospital in India.

Invasive fungal infections (IFI) are commonly seen in immunosuppressed individuals but their epidemiology in critically ill patients has not been well described. The aim of this study was to determine the frequency, risk factors and outcome of invasive fungal infections in a medical intensive care unit. A prospective observational study was carried out between August 2016 and March 2018 in the medical intensive care unit. Patients above the age of 14 years with endotracheal intubation and/or central venous catheter for at-least three days and sepsis (not responding to 48 hours of intravenous antibiotic therapy) were included in the study. Suitable samples were collected and were subjected to fungal diagnostics. Invasive fungal disease was defined according to standard guidelines. Of the 100 recruited patients, a total of 11 patients had invasive aspergillosis, three patients had invasive candidiasis and one patient had both invasive aspergillosis and mucormycosis. IFI was more commonly seen in patients with auto-immune diseases (p = 0.002, odds ratio-10.13 (95% CI: 2.3-44)). A mortality of 73% was observed in patients with IFI. In conclusion, IFI, especially aspergillosis is grossly under-reported in critical settings. Early suspicion, thorough investigation and timely diagnosis may alleviate patients of significant mortality and morbidity.
