Overview

A patient with fever may often come with rash.There are several causes for rash in febrile patients.Rash caused by infectious agents may have mild to severe outcome,so it is very important to diagnose the cause and treat accordingly.There can be some non-infectious causes as well.To diagnose efficiently a complete history must be taken which includes history of recent travel, contact with animals, medications, and exposure to forests and other natural environments. Additionally, time of onset of symptoms and morphology, location, distribution of the rash are be helpful in the clinical diagnosis.The most common causes are Dengue hemorrhagic fever, Rocky Mountain spotted fever (RMSF), Scarlet fever, Toxic Epidermal Necrolysis (TEN),Stevens-Johnson Syndrome (SJS), Henoch-Schonlein Purpura (HSP), Kawasaki disease, Lyme disease, Endocarditis, Disseminated gonococcal infection,Autoimmune vasculitis, Systemic lupus erythematosus (SLE),Rheumatoid arthritis,Sjogren’s syndrome, Varicella, Necrotizing fasciitis, Rubella, Measles.Usually,skin rashes are nonspecific and self-limited.If it is caused by viral infections unlike bacterial infections, they do not respond to antibiotics, so treatment usually focuses on relieving symptoms.If it is caused by bacterial infection specific antibiotic is prescribed.The treatment of non-infectious rashes depend on the underlying cause.

Lyme disease

Treatment: ❑ Discontinuation of the offending agent ❑Optimizing fluid and electrolyte levels ❑ Admit to ICU

Treatment: ❑ Mild cases (EM minor) require only symptomatic support ❑Give analgesics, cold compresses, topical steroids ❑ Treatment of the specific cause if it is found and dermatological followup visit should be scheduled ❑In Erythema major more aggressive care is needed, start with discontinuation of the causative agent ❑Fluid and electrolyte balance, analgesics for pain ❑Clean the wounded area, Silver sulfadiazine should NOT be used ❑If oral lesions are present, soothing solution can be used ❑Steroid use may give rise to further complications than benefit ❑Dermatological and opthalmologic consultation (if eyes are involved).

Treatment: ❑ Doxycycline is the first-line treatment in nonpregnant adult patients ❑Amoxicillin can be used in children

Treatment: ❑ Ceftriaxone is first-line therapy. Vancomycin should be added ❑Rifampin is used as prophylaxis in close contacts of the patients,alternatively single-dose ciprofloxacin and IM ceftriaxone can be administered ❑ Dexamethasone can reduce neurologic sequelae if given early,even before administering antibiotics

Treatment: ❑ Doxycycline is the drug of choice in all nonpregnant patients and children. ❑ Pregnant patients can be treated with chloramphenicol

Treatment: ❑ Doxycycline is the first-line treatment in nonpregnant adult patients ❑ Children can be treated with amoxicillin.

If patient comes with Petechial/Purpuric rash

Fever with Petechial rash/Perpuric rash

Endocarditis

Henoch-Schonlein purpura

Disseminated gonococcal infection

Rocky Mountain spotted fever

Meningococcemia

DIC

Purpura fulminans

TTP

Treatment: ❑ Initial empiric therapy is Vancomycin or Ampicillin/Sulbactam plus an Aminoglycoside . ❑Rifampin is added in patients with prosthetic valves ❑Valve replacement should be considered in selected patients with infectious endocarditis. ❑Antimicrobial prophylaxis before certain dental and other procedures.

Treatment: ❑ Only supportive care, ❑Some patients need hospitalization for pain control, kidney biopsy, and/or administration of immunosuppressant agents or, occasionally, IVIG

Treatment: ❑ Patients with Disseminated gonococcal infection should be treated for at least 1 week with IV ceftriaxone. ❑ Treatment duration should be extended in patients who do not improve adequately

Treatment: ❑ Doxycycline is the drug of choice in all nonpregnant patients and children. ❑ Pregnant patients can be treated with chloramphenicol

Treatment: ❑❑ Ceftriaxone is first-line therapy. Vancomycin should be added ❑Rifampin is used as prophylaxis in close contacts of the patients,alternatively single-dose ciprofloxacin and IM ceftriaxone can be administered ❑ Dexamethasone can reduce neurologic sequelae if given early,even before administering antibiotics

Treatment: ❑ The primary treatment of DIC is treatment of the underlying condition ❑ In patients with DIC and bleeding or at high risk of bleeding and a platelet count of <50 x 10(9)/l transfusion of platelets should be considered but non-bleeding patients with DIC, prophylactic platelet transfusion is not given unless there is a high risk of bleeding. ❑Activated partial thromboplastin time (aPTT), administration of fresh frozen plasma (FFP) may be useful in DIC patients with prolonged prothrombin time (PT). ❑In patients where FFP can not be used due to chances of fluid overload,factor concentrates can be used. ❑ Patients with DIC with a primary hyperfibrinolytic state and severe bleeding can be treated with lysine analogues, such as tranexamic acid, 1 g every 8 hourly is administered.

Treatment: ❑ Admit to ICU immediately and hematology consultaion is needed ❑First-line therapy is treatment of the underlying cause ❑ Folate, vitamin K, fresh frozen plasma (FFP), cryoprecipitate, platelets, and red blood cell transfusions are given as needed; heparin can be used if there is any thrombi

Treatment: ❑ Immediate hematology/oncology consultation ❑Treatment of the underlying cause is done,Plasmapheresis, FFP are used. ❑ Platelets should not be given as it will precipitate additional thrombus formation
