A critical appraisal of mucormycosis in COVID- 19 patients in a tertiary care centre in India

Background and Purpose: Morbidity and mortality of opportunistic fungal infections in COVID-19 patients are less studied and defined. The patients receiving immunosuppressive therapy, broad-spectrum antibiotics, corticosteroids, and invasive and non-invasive ventilation are the high-risk groups.Materials and Methods: The demographic profile as well as clinical and radiological findings of all the patients with COVID-19 suspected of Mucormycosis (MM) were recorded. The tissue samples from all the patients were sent for microbiological (KOH mount and culture) and histopathological analysis for confirmation of MM.Results: In total, 45 COVID-19 patients suspected of MM were included in the study an MM was confirmed in 42 patients. The mean age of the patients was 50.30±14.17 years with a female: male ratio of 1.1:1. The most common symptom was headache (52.38%) followed by purulent nasal discharge (38.09%) and facial pain in 33.33% of the cases. The ocular symptoms included a diminution of vision (33.33%) and redness of the eye (2.38%).The most common site of involvement was rhino-orbital (42.85%) followed by sinonasal (23.80%) and rhino cerebral (19.04%). Majority (38.09%) of the patients were diagnosed with stage II of Rhino-orbital-cerebral Mucormycosis (ROCM) based on radiology. A history of diabetes mellitus and steroids was present in 97.61% and 85.71% of the cases, respectively. Moreover, KOH was positive for MM in 97.61% of the cases while the culture was positive in only 35.71% of the cases. In addition, on histopathology, MM was confirmed in 64.28 % of the cases. Mixed growth with Aspergillus species and Rhizopus species was observed in 14.28% of the cases in culture and 11.90% of the cases in histopathology test. Furthermore, angioinvasion was found in 23.80% of the cases according to the histopathology test.Conclusion: Based on the results, the most common conditions associated with MM in COVID-19 patients were diabetes mellitus and steroid therapy. A high level of clinical suspicion aided with diagnostic tests, including KOH mount, culture, histopathology, and radiology which helped the early detection of opportunistic fungal infection in COVID-19 patients to ensure timely treatment

Increasing Trends of Leptospirosis in Northern India: A Clinico-Epidemiological Study

Leptospirosis is often not suspected by physicians in patients with acute febrile illnesses reporting from supposedly “non-endemic areas,” including north India. Clinical manifestations are protean, and complications can affect most organ systems, including liver, kidneys, lungs, and the central nervous system. Timely diagnosis and specific therapy can reduce severity of illness and, in turn, mortality. In this study conducted at a tertiary care center in north India, we find how a much-neglected disease entity has emerged as a major cause of acute febrile illness in a so called “non-endemic area.” Incidence is increasing yearly. The majority of patients were from a rural background, and were farmers or farm labourers. Poor hygiene, contact with animals, rat infestation of houses, and contact with stagnant dirty water are the major determinants of disease. Apart from the usual symptoms of intermittent fever with chill and rigor, hepatosplenomegaly, renal decompensation, muscle pain and tenderness, and conjunctival suffusion, signs and symptoms indicating involvement of the respiratory and central nervous systems were also commonly observed. Severe complications resulting in mortality do occur and is especially due to late suspicion among primary level physicians, and the resulting inappropriate therapy

Atypical chronic osteomyelitis of femur post-traumatic post-implantation by Achromobacter denitrificans: A case report

Background: The bacteria, Achromobacter are present ubiquitously in the moist environment. Infections due to Achromobacter have mostly been reported in immunocompromised patients. However, the microorganism has also been associated with nosocomial infections even in healthy subjects. Report: We report chronic osteomyelitis caused by Achromobacter denitrificans in a 44-year-old male with a history of femoral intramedullary nail in situ. The organism was confirmed by matrix assisted laser desorption ionization-time of flight mass spectrometry (MADI-TOF MS). Clinical management: The patient was managed with implant removal, surgical debridement and culture-directed antibiotic therapy that led to clinical cure. Conclusion: Identification of implant associated infection poses a serious challenge to surgeons and clinical microbiologists. Atypical pathogens must always be considered with a history of any implant in a case of chronic osteomyelitis

Cryptococcal granulomas in an immunocompromised HIV-negative patient

Disseminated cryptococcosis usually occurs in immunocompromised individuals with defective cell-mediated immunity, most commonly seen with HIV infection. We present a case of disseminated cryptococcosis in an HIV-negative male patient who presented with headache, fever, altered sensorium of short duration and multiple cutaneous lesions. An emergency CT scan of the head showed multiple intracranial and intraventricular granulomas. Routine laboratory investigations were within the normal range. A CSF examination revealed capsulated yeasts on India ink and a culture yielded cryptococcus neoformans. A cryptococcal antigen test by latex agglutination kit was positive. A biopsy revealed multiple capsulated yeasts cells in the cutaneous lesions, which were consistent with cryptococcus neoformans. The patient was successfully treated with Amphotericin B and Fluconazole with regression of cranial and cutaneous lesions
