Scrub typhus manifesting with intracerebral hemorrhage: Case report and review of literature

Three cases of scrub typhus with hemorrhage: a case report and literature review

Scrub typhus (ST) is an acute focal infectious disease that is caused by Orientia tsutsugamushi. The Asia-Pacific region is an area of relatively high incidence. There is a high incidence in China, principally owing to the disease being endemic in the south of the country. The main source of ST infection is rats, which act as reservoirs of infection after being bitten by the chigger mite, and the human population is generally susceptible to the disease. ST can be controlled and treated successfully if antibiotics are administered in a timely manner. However, because it does not have a specific clinical manifestation, it is difficult to distinguish ST from other febrile diseases in clinical practice. Therefore, rapid diagnostic methods are still needed to help clinicians make a timely diagnosis. Here, we share three cases of patients with ST who experienced hemorrhage, but did not have typical skin lesions, such as eschar and ulcer, early in the course of their disease, and review the relevant literature regarding ST. We conclude that clinicians should pay attention to the risk of hemorrhage associated with this disease, and emphasize the importance of making an early diagnosis.

Sickle Cell Disease Presenting as Extradural Hematoma: An Extremely Rare Fatal Crisis

Sickle cell disease (SCD) is due to a gene mutation in the hemoglobin subunit beta gene, whose polymerization when deoxygenated disrupts the physicochemical properties of red blood cells, triggering pan-cellular activation and pathogenic processes such as hemolysis, vaso-occlusion, and ischemia-reperfusion, culminating in the disease's numerous and severe complication like hemorrhage. This case report highlights spontaneous extradural hematoma in a young adult with SCD as an acute neurological complication.

Clinical and biochemical profile of scrub typhus patients at a tertiary care hospital in Northern India

Background

Scrub typhus is a neglected rickettsial disease in India. Every year, we are facing outbreaks of Scrub typhus after Monsoon season. Patients present with a wide clinical spectrum ranging from pyrexia of unknown origin to multiple organ dysfunction. Some of these clinical features overlap with presentation of other tropical infections prevalent in Indian subcontinent, which leads to diagnostic dilemma and delay in diagnosis. Hence, we planned this study to know the demographic, clinical and biochemical profile of scrub typhus patients.

Methods

This was an observational study conducted in department of Medicine, King George's Medical University Lucknow, India a leading tertiary care hospital of Northern India. All scrub typhus patients were evaluated by detailed history, examination and laboratory tests.

Results

We enrolled 52 patients in our study. The mean age of the patients was 35.17 ± 16.90 years with majority (82.7%) of patients from rural background. All the patients had fever with an average duration of 9.6 ± 2 days. Most of the patients developed hepatitis (69.2%) followed by acute encephalitis syndrome (47%), acute kidney injury (23.1%) and acute respiratory failure (19.2%). Eschar was found in 11 patients (21.2%).

Conclusion

Scrub typhus is often misdiagnosed or diagnosed late due to its wide clinical spectrum overlapping with clinical presentation of other commonly prevalent tropical diseases. One should always consider the differential diagnosis of scrub typhus while evaluating a young febrile patient of rural background, with features of single or multiple organ dysfunction and laboratory findings of leucocytosis, thrombocytopenia and elevation of transaminases.
