Abstract

Abstract Haemophagocytic lymphocytosis (HLH) is a rare life-threatening syndrome caused by the uncontrolled activity of cytokines, natural killers, and macrophages, which can alter the activity of the organism, resulting in multiple organ dysfunction and mortality. Fever, splenomegaly, coagulopathies, dyspnea, changes in mental status, or irritability may be associated with HLH diseases. Depending on the underlying causes, such as bacterial or viral infections, HLH may be primary, hereditary, or secondary. The early diagnosis and treatment of patients are directly related to their prognosis and clinical outcome. On the other hand, HLH can present a number of obstacles, particularly for children and newborns, as well as hematological defects which might cause other autoimmune disorders. Case presentation: We present a case of a 28-year-old male patient admitted to the hospital with a history of persistent high grade fever for two weeks, right lower limb swelling three weeks prior to admission, and right side weakness for one month. Aside from being addicted to cannabis for three years, the patient has no prior medical history. On admission, the patient was awake, conscious, oriented, and hemodynamically stable. A complete blood count, ultrasound examinations, and a whole-body CT scan revealed that the results were favorable for multiple enlarged lymph nodes and hepatosplenomegaly. The patient was given acyclovir, Vfend, Colistin, Targocid, Tinam, Septrin, and anticoagulant during the follow-up. The patient's clinical condition was rapidly deteriorating; a bone marrow biopsy was performed, which revealed haemophagocytosis; and dexamethasone was started. The patient's clinical condition deteriorated during his hospital stay until he went into cardiac arrest and had to be resuscitated for 30 minutes with pulseless electrical activity. Background and Aim: This case suggests that we should be vigilant to the patient who is admitted to the hospital with symptoms for unknown reasons, in order to diagnose HLH as soon as possible and clarify its cause, and it also puts several theories regarding the pathogenicity of this disease in our hands, which will be described in this case, making this case a subject for discussion and research in the medical field. Conclusion: Haemophagocytic lymphocytosis (HLH) is a severe inflammatory disease that improperly controls the body's immune response. Viruses and bacterial infections are just two examples of the various etiological causes that can cause it. Lab results and symptom presentations that are particular to the primary infection can indicate it. Diagnosis and treatment must be provided as soon as possible in order to reduce morbidity and mortality.
