We present a rare case of a 4-year-old boy with newly diagnosed Henöch-Schonlein purpura (HSP) affecting the scrotum and penis. The patient presented to the emergency department with palpable purpura symmetrically distributed over the lower limbs. [ncbi.nlm.nih.gov]

It is the presenting sign in 50 percent of patients. 12 Some patients present with predominantly petechial lesions, some present with mainly purpuric lesions, and others present with a mixture of lesion types. [aafp.org]

Careful examination of skin including the bottom of the feet can help to direct the diagnostic workup for children with abdominal pain. [ncbi.nlm.nih.gov]

Based on the pathophysiology that is suspected, a differential diagnosis can be generated and an appropriate workup can be initiated. [link.springer.com]

A laboratory workup, including a complete blood cell count and differential, prothrombin time, partial thromboplastin time, comprehensive metabolic panel, creatinine kinase test, urinalysis, and chest radiograph, was normal, but his erythrocyte sedimentation [mdedge.com]

See Workup for more detail. Management The therapy of choice for TTP is plasma exchange with fresh frozen plasma. [emedicine.medscape.com]

Previous workup by her primary care provider included complete blood count (CBC), complete metabolic panel (CMP), and imaging of affected sites, all of which were unremarkable. [psychiatrictimes.com]

However, significant differences were detected for DAO and D-lactate after treatment in comparison to before treatment in the Montmorillonite experimental group (P .05). [ncbi.nlm.nih.gov]

When treatment is necessary, it is not due to the rash itself. Treatment is needed for causes such as leukemia, or effects including kidney failure. [medicalnewstoday.com]

What is the prognosis for patients with HSP? The prognosis (outlook) for patients with HSP is generally excellent. Nearly all patients have no long-term problems. The kidney is the most serious organ involved when it is affected. [medicinenet.com]

Prognosis Gastrointestinal or pulmonary bleeding can be life-threatening. The long term prognosis depends on the extent of the renal involvement. [orpha.net]

Both thrombocytopenia and purpura have been shown to have a complex etiologic pattern with multiple potential etiologic factors. [ashpublications.org]

The course varies according to the etiology, as do the diagnostic approach and treatment. This review discusses pigmented purpuras and some cutaneous vascular occlusion syndromes. [ncbi.nlm.nih.gov]

PLATELET DYSFUNCTION Congenital Etiologies. [aafp.org]

Regarding the etiology, prodromal viral illness has been described as an etiology of HSP. Though there is a higher occurrence of HSP in the late fall and spring, some patients are seen throughout the year. [journals.lww.com]

Here, we will review the epidemiology, clinical and molecular characteristics of HSP, as well as abnormalities of Th cell subsets in this disorder. [ncbi.nlm.nih.gov]

Summary Epidemiology SHP usually affects children and is rare in adults. Annual incidence in children is estimated at between 1/6,660 and 1/4,880, whereas it is estimated at around 1/1,000,000 in adults. The male-to-female ratio is 1.5:1. [orpha.net]

Abstract Immunoglobulin G is used to both prevent infection in primary immunodeficiency diseases (PIDs) and prevent bleeding in immune thrombocytopenic purpura. [ncbi.nlm.nih.gov]

Eight studies evaluated therapy to prevent persistent kidney disease in HSP. [cochrane.org]

However, they have not been shown to reduce the extent or severity of renal involvement, nor did they prevent the development of renal damage. [news-medical.net]

Can Henoch-Schönlein purpura be prevented or avoided? Doctors do not know how to prevent HSP. The disease is more common in boys than in girls. Children 2 to 11 years of age are more likely to be affected, but adults can get it too. [familydoctor.org]
