A 47-year-old female presented with acute severe pain in her limbs. Examination found absent pulses. Imaging showed diffuse narrowing of arteries without atherosclerosis. She was found to be HIV positive and on antiretroviral therapy. Her condition improved with steroids. HIV can cause various types of vasculitis. This case represents a large vessel vasculitis seen in HIV, termed Category III, which is a distinct clinical entity associated with HIV. Treatment involves steroids and antiretrovirals.

12. Emperically and urgently we treated this patient as a case of an acute & sever form of a large vessel vasculitis ,so we started
Pulse steroid one gram /day for 3 days .
IV pentoxyfilline every 8 hours .
Prophylactic dose of LMw heparin.
Low dose asprine.
And preparing her for CT angiography and other immunological assay.
13. CT ANGIOGRAPHY
Normal aortic arch ,descending thoracic and abdominal aorta with diffuse narrowing of both external iliac arteries with absence of atherosclerotic changes favor the diagnosis of peripheral vasculitis.

19. RESPONSE
Marked improvement of her ischemic pain after the 2nd dose of pulse steroid ,but the pulsations still was undetected.
With completing her lab . Investigations:
RF : -ve
ANA: -ve
P&C (ANCA): -ve
Virology:
HCV antibodies –ve
HBsAg -ve
22. SURPRISE
Our patient is an HIV patient since 16 years and she is already on HAART
1-Aluvia:lopnavir200 mg &50 ritonavir
2-Aurobindo:emtricitabine 200 mg and tenofovir disoproxil fumerate 300 mg.
She and her family denied all this history due to its social stigmata.
23. DILEMMA
Is this case is large vessel vasculitis associated with HIV or it is actually HIVrelated vasculitis????
What about its treatment???
Is it a mistake to start with pulse steroid???
How could we continue??????
24. HIV RELATED VASCULOPATHY
Since the beginning of the HIV era in the early 1980s much has been written about rheumatic and immunologic complications observed in this patient population, including the co-occurrence of systemic vascular inflammatory diseases .
Calabrase L H: Vasculitis and infection with the human immunodeficiency virus.Rheum Dis Clin North Am 1991; 17: 131-47
25.
26. TYPES
Category I refers primarily to vasculitides diagnosed according to ACR classification schemes that have been reported in the setting of HIV infection.
Category II refers to secondary forms of vasculitis (e.g. where a precipitin or mechanism can be identified such as a specific infection or drug induced hypersensitivity.
Category III describes those vascular disorders that appear to be unique and for which strong consideration should be given.

27. CATEGORY I PRIMARY VASCULITIS IN HIV
HIV has infected an estimated 75 million people worldwide over the past 25 years , it should not be surprising to find documented accounts of just about any form of vascular inflammatory disease reported on a chance association basis.
UNAIDS/WHO: AIDS epidemic update. December 2000: 1-28.

29. Miscellaneous disorders with vascular inflammation as a feature reported in HIV
Cutaneous PAN
Behcet’s syndrome
Primary angiitis of the central nervous system
Erythema nodosum.
Rheumatic fever ,Erythema elivatinum diutinum.
Degos disease
Angiocentric lymphoproliferative disorders
Coronary arteritis
Eaosinophilic vasculitis
Leukocytoclastic vasculitis with follicular accentuation
30. PATHOGENESIS
The pathophysiology of these reported cases is also unclear but may be due to direct or an indirect role for HIV itself. by way of uncontrolled immune activation with attendant cytokine release , which characterizes the underlying infection.
L.H. Calabrese Infection with the Human Immunodeficiency Virus type 1 and vascular inflammatory disease Clin Exp Rheumatol 2004; 22 (Suppl. 36):S87-S93.
31. CATEGORY II SECONDERY VASCULITIS
Given the immunopathology of progressive immunodeficiency and opportunistic infections. It is well known that vasculitis may arise in the course of virtually any type of infection (i.e,bacterial, fungal, mycobacterial, viral parasitic) and that such pathologic lesions may come about by way of direct angio-invasion or via aberrantly directed host-mediated immune defenses.
32. Secondary forms of vasculitis.
Infectious arteritis.
Cytomegalovirus .
Pneumocytstis carinii .
Toxoplamosis .
Herpes zoster associated .
Hepatitis C associated .
Drug-induced vasculitis .
Vasculitis associated with antiretrovirals .
33. CATEGORY III VASCULAR INFLAMMATORY DISORDER UNIQE TO HIV
(1) cerebral vasculopathy with aneursymal dilatation in HIV infected children.
(2) large vessel disease in HIV infected patients .
T V MULAUDZI Vasculopathy is a major feature of HIV disease. CME July 2009 Vol.27
34.
35. Aneurysms
This disease affects much younger patients The median age is between 30 and 40 years. However, the majority of patients infected with HIV are females and the reason for the male preponderance of aneurysmal disease is unknown.
The pathogenesis of the aneurysms is uncertain. Histology shows obliterative endarteritis involving the vasa vasora of the major vessels. These vessels are surrounded by neutrophils, which in turn are surrounded by a cuff of plasma cells, lymphocytes and monocytes. This eventually leads to thrombotic occlusion of the vasa vasora with transmural necrosis of the vessel wall, probably due to ischaemia.
36. The common sites for the aneurysms are the common carotid and the superficial femoral artery .They can, however, be found throughout the body, tend to be multiple, and typically have a multi- loculated appearance . Many are in fact false aneurysms due to disruption of the vessel wall at the point of transmural necrosis.
37.
38. OCCLUSIVE DISEASE
HIV-associated arterial occlusive disease is recognised as a specific clinical entity. As for aneurysmal disease, young males with a median age of 30 - 40 years are mainly affected; it is difficult to explain this male preponderance.
The underlying cause of occlusive disease is thought to be related to vasculitis. The histological findings are similar to those found in HIV-associated aneurysmal disease. It has been suggested that a hypercoagulable state might be involved. There have been reported findings of anti-phospholipid antibody syndrome, deficiencies of free protein S, protein C and anti- thrombin 3, but these have been sporadic reports.
39. Clinically most patients present with advanced disease and critical ischaemia affecting the lower limb. In most patients the disease is confined to one limb, for reasons that are obscure. It is interesting to note that on Duplex Doppler imaging there is what appears to be a pathognomonic sign with hypoechoic spotting within the arterial wall (string of pearls sign).

40. HIV& TAKAYASU
There is striking clinicopathologic overlap withTakayasu's disease.
Features of similarity include :
the young age of the patients, presence of multiple aneurysms, involvement of large vessels, arteritic and postarteritic changes of the vasa vasora, a temporal sequence of events (active and healing stages), and the absence of an obvious causative agent.
41. Differences from Takayasu's:
disease are the predominance of males, the proliferation of slit-like vascular spaces in the adventitia,the pronounced leukocytoclastic vasculitis of the vasa vasora, the absence of prominent intimal proliferation and atherosclerosis, and the clustering of the cases that coincides with the HIV/AIDS epidemic.
The overlap with Takayasu's disease is not surprising given its so called idiopathic etiopathogenesis and overlap with several arteritides. In other words, there is a chance association between H1Vand vasculitis.

43. TREATMENT
Therapy for HIV-associated vasculitis remains controversial and problematic, with the largest reported experience being that of Guillevin and colleagues who advocate a combination of glucocorticoids, apheresis and antiviral therapy .

44.
45. Standard treatment has been offered for aneurysms, including prosthetic grafts, and relatively recently, endovascular therapy has been performed with stent
occlusive disease
In 33 of 36 (71%) patients, salvage was attempted comprising thrombectomy with or without thrombolysis; bypass was attempted in the remaining three patients.
Of the 64 patients, who had chronic occlusive disease, primary amputation was necessary in 30 (47%) while no treatment was offered to nine (14%) who were deemed to be pre terminal.
Twenty-one patients were offered bypass surgery, and four an endovascular procedure
46. SO OUR DECISSION WAS:
To continue on 40 mg prednisolone
Oral pentoxyphylline
Low dose asprine
Follow up after two week:
She was very well no ischemic pain but only mild neuropathic pain for which pregabalin was prescribed.
Pulse was detected well in her RT radial ,ulner and brachial also her left dorsalis pedis and ant tibial.
Felt but weaker lt radial and ulner.
Still undetected in her RT dorsalis pedis.
47. NEW DOPPLER AFTER ONE MONTH
Patent venous and arterial system of both upper and lower limbs with no plaques or stenosis with only biphasic flow for follow up.

50.
51.
52. So we started gradual withdrwal of steroid dose 5mg every week till it was completely stopped.
Patient is now on pregabalin only and HAART.
Another doppler study was done after steroid withdrwal and it showed the same results.
54. DILEMMA
Is this case is large vessel vasculitis associated with HIV or it is actually HIVrelated vasculitis????
What about its treatment???
Is it a mistake to start with pulse steroid???
How could we continue??????
55. OUR CASE IS:
HIV RELATED LARGE VESSLE VASCULITIS
