COVID-19 associated multisystemic mucormycosis from India: a multicentric retrospective study on clinical profile, predisposing factors, cumulative mortality and factors affecting outcome.

PURPOSE: The clinical course of COVID-19 has been complicated by secondary infections, including bacterial and fungal infections. The rapid rise in the incidence of invasive mucormycosis in these patients is very much concerning. COVID-19-associated mucormycosis was detected in huge numbers during the second wave of the COVID-19 pandemic in India, with several predisposing factors indicated in its pathogenesis. This study aimed to evaluate the epidemiology, predisposing factor, cumulative mortality and factors affecting outcomes among the coronavirus disease COVID-19-associated mucormycosis (CAM). METHODS: A multicenter retrospective study across three tertiary health care centers in Southern part of India was conducted during April-June 2021. RESULTS: Among the 217 cases of CAM, mucormycosis affecting the nasal sinuses was the commonest, affecting 95 (44%) of the patients, orbital extension seen in 84 (38%), pulmonary (n = 25, 12%), gastrointestinal (n = 6, 3%), isolated cerebral (n = 2) and disseminated mucormycosis (n = 2). Diabetes mellitus, high-dose systemic steroids were the most common underlying disease among CAM patients. The mucormycosis-associated case-fatality at 6 weeks was 14%, cerebral or GI or disseminated mucormycosis had 9 times higher risk of death compared to other locations. Extensive surgical debridement along with sequential antifungal drug treatment improved the survival in mucormycosis patients. CONCLUSION: Judicious and appropriate management of the predisposing factor and factors affecting mortality associated with CAM with multi-disciplinary approach and timely surgical and medical management can be much helpful in achieving a successful outcome.

Wernicke's encephalopathy in women with hyperemesis gravidarum - Case series and literature review.

Whilst nausea affects around 80% of pregnant women, hyperemesis gravidarum, an extreme form of the same, affects only 0.5% to 3%, but may lead to severe nutritional deficiency. Wernicke's encephalopathy is an acute neuropsychiatric disorder which occurs due to thiamine deficiency and needs emergency treatment to prevent neurological morbidity and mortality. Wernicke's encephalopathy is characterised by a clinical triad of oculomotor abnormalities, cerebellar dysfunction and altered mental state. Korsakoff's psychosis is a chronic condition and consequence of Wernicke's encephalopathy, resulting from its delayed treatment. Wernicke's encephalopathy is a well-known complication of chronic alcohol abuse. Not many are aware of its association with hyperemesis gravidarum. Although it is a rare complication, if not diagnosed and treated promptly, it may result in permanent and irreversible neurological sequelae. The objective of our retrospective observational study was to analyse the clinical profile and outcome (short and long term) in a rare yet preventable complication of pregnancy.

Need for guidelines for the combined management of pregnancy and dengue: a retrospective study from an Indian tertiary care maternity hospital.

The incidence of dengue has risen in India in recent years. Evidence suggests that dengue in pregnancy may be associated with adverse maternal and fetal outcomes. The aim of our study was to analyse outcomes in pregnant women with confirmed dengue infection who had the benefit of close monitoring and intensive management at a tertiary maternity facility. We reviewed hospital data of 44 (0.11%) such women at Fernandez Hospital, a tertiary maternity unit, during the five-year period from 2011 to 2016. Maternal and fetal variables were collected from case sheets. Dengue haemorrhagic fever was seen in 15.9% and dengue shock syndrome in one fatal case (2.2%). Thrombocytopenia was seen in 31 cases (70.4%) and 14 (31.81%) received platelets transfusions. Fetal outcomes in our series were favourable, except for one stillbirth, with 45.4% preterm deliveries and 15.9% small for gestational age babies. Dengue in pregnancy is definitely associated with maternal and fetal morbidity and mortality. A high index of suspicion of dengue is required in pregnant women with pyrexia and thrombocytopenia.

Comparative Evaluation of Safety and Efficacy of Glimepiride and Sitagliptin in Combination with Metformin in Patients with Type 2 Diabetes Mellitus: Indian Multicentric Randomized Trial - START Study.

BACKGROUND AND OBJECTIVE: Modern sulfonylureas like glimepiride offer effective glycemic control with extrapancreatic benefits and good tolerability. The objective of the present study was to evaluate and compare safety and efficacy of glimepiride and sitagliptin in combination with metformin in patients with type 2 diabetes mellitus (T2DM). METHODS: In this open-label, randomized, comparative, multicenter study, a total of 305 T2DM patients who were either drug naïve or uncontrolled on metformin were randomized to glimepiride 1 or 2 mg/sustained-release metformin 1000 mg once daily (glimepiride group, n = 202) or sitagliptin 50 mg/metformin 500 mg twice daily (sitagliptin group, n = 103) for 12 weeks. Primary endpoint was change in glycosylated hemoglobin (HbA1c). Secondary endpoints were change in fasting plasma glucose (FPG), postprandial plasma glucose (PPG), body mass index (BMI) and to assess overall safety profile. RESULTS: At 12 weeks, there was a statistically significant difference in the mean HbA1c reduction in glimepiride group (0.42%) as compared to sitagliptin group (0.30%) (P = 0.001). Mean reduction in FPG and PPG was also statistically significant in the glimepiride group as compared to the sitagliptin group (P = 0.008). There was no significant difference in terms of change in BMI (0.07 ± 0.39 kg/m2 vs. 0.08 ± 0.31 kg/m2) in glimepiride and sitagliptin groups, respectively, (P = 0.644) between both the groups. The incidences of hypoglycemic events were also comparable among both the groups. CONCLUSION: In T2DM patients, glimepiride/metformin combination exhibited significant reduction in glycemic parameters as compared to sitagliptin/metformin combination. Moreover, there was no significant difference between both the groups in terms of change in BMI and incidence of hypoglycemia.

Mixed connective tissue disorder and Castleman's disease.

We present a 16-year-old girl who presented with polyarthritis in association with Raynaud's phenomenon, malar rash, oral ulcers, photosensitivity and alopecia of 6 months duration. On evaluation, it emerged that she had a mixed connective tissue disorder with a mesangio-proliferative glomerulonephritis. Her Chest radiograph revealed a well defined left mid and lower zone opacity with evidence of a hilar mass on CT Thorax. Histopathological examination following CT guided biopsy of the mass revealed a hyaline vascular type of Castleman's disease. Mixed Connective Tissue Disorder with Castleman's Disease is a rare association; the patient presenting with varied and interesting manifestations. It is important to understand this association in view of management. The exact etio-pathogenesis of the autoimmune manifestations in patients with Castleman's disease is not clear. Treatment with immunosuppression can suppress both immune manifestations and result in tumour regression as well.

Acute febrile illness caused by hantavirus: serological and molecular evidence from India.

Study of hantavirus infections in India is in its early stages. As early symptoms of hantavirus disease can be non-specific and the diagnosis confirmed only by laboratory testing, use of appropriate diagnostic tools is important. To improve the diagnosis of hantavirus infections in India, commercial ELISA systems followed by indirect immunofluorescence assays were used to detect anti-hantavirus IgM and IgG in samples from patients with acute febrile illness. Of 347 patients tested, 5.2% showed serological evidence of hantavirus infection. Sequences obtained from patients showing molecular evidence of hantavirus infection were related to Hantaan virus. In the absence of mu-capture ELISA, we recommend the use of combination testing systems in areas non-endemic for hantavirus infections. In India there is an increased risk of rodent-borne infections and the differential diagnosis of undifferentiated febrile illness should include hantavirus infection.

Sternal tuberculous osteomyelitis presenting as a pulsatile swelling.

Primary sternal tuberculous osteomyelitis is a rare form of tuberculous osteomyelitis. We report a case of a young adult with primary tuberculous osteomyelitis of the sternum who presented with a pulsatile anterior chest wall swelling. Computed tomography of the thorax revealed a hypodense lytic lesion in the body of the sternum that had eroded into the anterior mediastinum where it lay in close contact with the right ventricle, resulting in the clinically evident transmitted pulsations. Among the protean manifestations of tuberculosis this case illustrates a unique presentation as a pulsatile chest wall mass.
