Abstract

Scrub typhus caused by organism Orientia tsutsugamushi and transmitted to humans by the bite of a leptotrombidium mite (chigger). Although eschar formation is one of the important signs that aid in diagnosis, multiple eschar formation is a rare presentation. Although scrub typhus causes multiple organ dysfunction, the pancreas involvement is rare. Here, we describe a patient with scrub typhus with multiple eschars complicated with acute pancreatitis and acute kidney injury.

 Introduction



Scrub typhus caused by Orientia tsutsugamushi and transmitted to humans by the bite of a leptotrombidium mite (chigger). Most patients of scrub typhus occur in rural areas of Southeast Asia, Indonesia, China, Japan, India and northern Australia. Eschar aids in early diagnosis of scrub typhus. Scrub typhus causes multi-organ dysfunction, yet involvement of pancreas is uncommon. Here, we report a patient with scrub typhus with multiple eschars complicated with acute pancreatitis and acute kidney injury.

 Case Report



A 50-year-old female presented with abrupt onset of high-grade fever associated with chills and rigors of 3-day duration. She also had 4–5 episodes of vomiting per day. The vomiting was non-bilious, non-blood stained, non-projectile and contained food particles of the past 3 days. She had a history of epigastric pain for 3 days. She also had breathlessness, facial puffiness and lower limb swelling for 3 days. She also had a history of decreased urine output which for 3 days. On examination, eschars were found on the right and left axilla and on right side of the neck. Anaemia, subconjunctival haemorrhage and paedal odema were also present. There were no jaundice and lymphadenopathy. She had bilateral crackles and hepatomegaly. Blood pressure was 90/60 mmHg. Laboratory testing showed serum creatinine 8.02 mg/dL, blood urea 186 mg/dL, serum sodium 131 mEq/L, serum potassium 5.0 mEq/L, serum amylase 74 IU/L, serum calcium 7.7 mg/dL, haemoglobin 10.6 g/dL, total leucocyte count 10,500 cells/mm3 and platelet count 193,000/mm3. Scrub typhus was diagnosed by the positive qualitative immunoglobulin M enzyme-linked immunosorbent assay (In Bios International Inc., Seattle, USA). The tests done for malaria, dengue, leptospira were negative. Computed tomography (CT) revealed bulky head of pancreas, free fluid around porta hepatis and pancreas, peripancreatic and mesenteric fat stranding, suggestive of acute pancreatitis. CT also showed the size of kidneys: right: 12.7 cm × 4.9 cm, left: 12.9 cm × 4.1 cm; both kidneys were bulky, bilateral perinephric fat stranding noted [Figure 1], calculus measuring 6 mm noted in mid pole and 4 mm in lower pole of left kidney.{Figure 1}

The treatment administered included nil peroral, parenteral doxycycline, proton pump inhibitors and haemodialysis for 6 sessions. The patient remained in the intensive care unit till the end of the dialysis sessions and improvement in urine output. Later, in the ensuing 6 weeks, the urine output improved to >3.0 L per day and serum creatinine values declined to 1.30 mg/dL. After 4 weeks of discharge, patient presented to nephrology. The serum creatinine and serum amylase have returned to normal.

 Discussion



Scrub typhus is a febrile illness associated with multi-organ dysfunction. The clinical features were gastrointestinal presentations such as duodenal ulcer perforation, peritonitis, acute acalculous cholecystitis; respiratory manifestations such as acute respiratory distress syndrome; neurological manifestations such as meningoencephalitis and acute renal failure, disseminated intravascular coagulation and myocarditis. However, acute pancreatitis is a rare presentation. The cause of acute pancreatitis in scrub typhus is not known. The proposed mechanism is endothelial invasion of microorganisms causing vasculitis and perivasculitis.[1] Our patient presented with fever, eschars, positive serology for rickettsial infection and CT suggested acute pancreatitis. There were a few reports of acute pancreatitis with scrub typhus. The reports included both as an isolated infection[1],[2],[3] and as a part of mixed infection.[4],[5] Infectious causes of acute pancreatitis include mumps, coxsackievirus, cytomegalovirus, mycoplasma, legionella, Salmonella and Aspergillus. Mortality in scrub typhus varies from 12% to 50%.[2] The reported mortality rate due to scrub typhus complicated with acute renal failure was 29.7%,[2] and when associated with acute pancreatitis, it was 42.8%.[1]

The final diagnosis of scrub typhus leading to acute pancreatitis had been based on clinical, biochemical and radiology features of acute pancreatitis in the patient of scrub typhus and without any other causative factor for acute pancreatitis.
