Evidence of hepatitis C virus antibodies in the cryoprecipitate of patients with mixed cryoglobulinemia.

OBJECTIVE: To describe the clinical features of 8 patients with mixed cryoglobulinemia and hepatitis C virus (HCV) infection. METHODS: A clinical study of the patients was performed. Anti-HCV antibodies were determined by ELISA and confirmed by immunoblot (RIBA) in the sera and in the cryoprecipitate. RESULTS: All patients had liver dysfunction, while most had arthralgias and/or arthritis, purpura, peripheral nervous system involvement and renal disorders. Cryocrits ranged from 1 to 6%. Six patients had type III mixed cryoglobulinemia and the remaining 2 had type II. History of blood transfusion was recorded in 2 patients. Hepatitis B virus (HBV) markers were negative in all sera samples. The cryoprecipitate of 7 patients was negative for HBV markers, but anti-HCV antibodies were positive by both ELISA and RIBA. CONCLUSION: After reviewing published reports and discussing the possible role that hepatitis C virus plays in the pathogenesis of mixed cryoglobulinemia, we conclude that HCV may stimulate immune complex formation and produce cryoglobulinemia. Therefore its investigation is recommended before the diagnosis of "essential" mixed cryoglobulinemia is established.

[Capillaroscopy in vasculitis].

A prospective study of the capillaroscopy changes in 15 patients afflicted with vasculitis is presented. 2 of them had classic polyarteritis nodos (PAN), 3 had Churg-Strauss allergic angiitis and granulomatosis, 2 had hypersensitivity vasculitis (HV), 6 had giant-cell arteritis (GCA) and 2 had polyangiitis overlap syndrome (POS). Periungual capillaroscopy (PC) showed isolated changes in 11 patients (73%). We observed more changes in those cases with active disease (83% vs. 67%); they were mainly microhemorrhage (without any statistical significance). There were no more findings in patients with a more generalised affliction (nervous system, kidneys and/or skin) than in the others. In conclusion, the capillaroscopy findings were few and non-specific. PC is a diagnostic method of negligible value in this type of disease.

[Systemic vasculitis as a cause of fever of unknown origin].

A prospective clinical study (1974-1988) was carried out in 33 patients with several types of systemic vasculitis (SV) presenting as fever of unknown origin (FUO) according to the 1961 Petersdorf and Beeson's criteria. Histological confirmation, either from biopsy or necropsy, was available in all cases. The types of SV with FUO were: panarteritis nodosa (PAN) (14 cases), giant cell arteritis (GCA) (13 cases), and overlapping polyangiitic syndrome (OPS) (6 cases). In PAN, the clinical features associated with fever at the onset of the disease were remarkably nonspecific: constitutional symptoms (85%), arthromyalgia (50%), nonspecific abdominal pain (28%), and irritative cough (28%). In the whole course of the cases of GCA a significantly smaller frequency of presentation of local arterial symptoms and polymyalgia rheumatica (p less than 0.01) was found in the subgroup of patients with FUO than in those without it. As regard laboratory data, a higher increase of serum alkaline phosphatase (p less than 0.05) was found in the cases of PAN and OPS with FUO. Striated muscle biopsy and arteriography were the most useful investigations in the diagnosis of PAN. The study that gave the diagnosis in the cases of GCA was temporal artery biopsy.
