TL;DR
This case highlights the complexity of managing immunocompromised patients with unexplained fever and neurological symptoms, emphasizing the need for further research into the potential neurological effects of Giardia infection.
Abstract
X-linked agammaglobulinemia (XLA) is a rare immunodeficiency caused by a mutation in Bruton's tyrosine kinase, resulting in profoundly low immunoglobulin levels and susceptibility to recurrent infections. We report a 14-year-old patient with XLA who presented with persistent fever, bloody diarrhea, and headache suggestive of pachymeningitis. The patient had chronic giardiasis. His clinical condition deteriorated with worsening thrombocytopenia, hepatitis, and minimal diffuse dural thickening on brain magnetic resonance imaging, interpreted as pachymeningitis. Empirical immunosuppressive therapy was initiated, but the patient ultimately succumbed to illness. Although Giardia has been linked to various extra-intestinal manifestations, its association with meningitis or pachymeningitis is not reported. This case highlights the complexity of managing immunocompromised patients with unexplained fever and neurological symptoms, emphasizing the need for further research into the potential neurological effects of Giardia infection.
A case of a patient who presented to the emergency department with symptoms of sore throat, fever, difficulty swallowing, and a patchy rash, leading to a suspicion of immunodeficiency and Arcanobacterium haemolyticum infection.

Introduction: Gastrointestinal basidiobolomycosis is an uncommon invasive fungal infection caused by Basidiobolus ranarum, an environmental mould endemic to the arid south-west of Saudi Arabia and to a handful of other hot, dry regions. Its non-specific presentation routinely invites misdiagnosis as inflammatory bowel...

Celiac disease is an immune-mediated enteropathy precipitated by gluten in genetically susceptible individuals. Although diarrhea, weight loss, and malabsorption are classical features, extraintestinal presentations are increasingly recognized. Pancytopenia as the initial manifestation of adult celiac disease is rare a...

Hereditary angioedema with C1-inhibitor deficiency (HAE-C1INH) is a rare bradykinin-mediated disorder that may present predominantly with gastrointestinal symptoms, leading to diagnostic delay and unnecessary interventions. We report a 26-year-old man with recurrent abdominal pain, watery diarrhea, bowel wall edema, an...
In recent years, the incidence of tick-borne diseases has been steadily increasing. Anaplasma phagocytophilum is a Gram-negative obligate intracellular bacterium transmitted by ticks of the Ixodes genus. Human granulocytic anaplasmosis typically presents with fever, headache, chills, malaise, and myalgia, while rash an...
