Typhoid Fever Complicated with Bowel Perforation in an HIV Patient
Abstract Background Patients with HIV infection often develop multiple complications and comorbidities, including malignancies and opportunistic infections. The association of HIV infection with typhoid fever remains unclear, though there is a clear risk of typhoid in HIV infected persons. Therefore, the diagnosis of typhoid should be considered in HIV infected individuals, mainly when they present with severe ulcerative diarrhoea. Case Presentation A 38-year-old gentleman presented with fever with significant weight loss and anorexia for eight months. He had worked abroad in a middle east country and had recently returned to Sri Lanka. On examination, he was thinly built with a BMI of 18 kg/m2. The initial full blood count revealed lymphopenia, anaemia and thrombocytopenia. He also had mild hyponatremia. His HIV Ag/Ab combo assay became positive, and he was found to have a low CD4 count. While on antiretroviral therapy, he developed nausea, vomiting and diarrhoea while continuing the preexisting fever followed by severe dyspnoea and epigastric pain and tenderness associated with tachypnoea, tachycardia and hypotension. The urgent chest X-ray revealed gas under the diaphragm. An urgent exploratory laparotomy was done, and he was found to have distal ileal perforation with a typhoid ulcer which was histologically confirmed later. During the postoperative period, the patient developed severe pneumonia, scummed despite all the resuscitation care given. Conclusion Fever in HIV patients could be due to HIV itself, opportunistic infections or malignancies. The diagnosis of typhoid should be considered in HIV infected individuals, mainly when they present with severe ulcerative diarrhoea, constipation or bowel perforation. Salmonella typhi infection in HIV/AIDS patients may cause life-threatening complications, where the case fatality rate of typhoid significantly increase when present concurrently with HIV, and the mortality further increases with delayed diagnosis.
