Adult Henoch-Schönlein purpura associated with malignancy.

OBJECTIVE: Malignancies are among the well-established causes of vasculitis. We studied the association between adult Henoch-Schonlein purpura (HSP) and malignant neoplasms. METHODS: We retrospectively reviewed 14 cases of adult HSP diagnosed during a 6-year period and found a malignant neoplasm in four. Fifteen reports of adult HSP with malignant disease were identified in the literature. These 19 cases were compared with 158 adults who had HSP but no malignancy and who where reported in the literature. RESULTS: Most (63%) of the malignant neoplasms associated with adult HSP were solid tumors: lung, n = 6; prostate, n = 2; breast, n = 1; renal, n = 1; stomach, n = 1; and small bowel, n = 1. Hematologic malignancies (37%) included non-Hodgkin lymphoma, n = 2; Hodgkin disease, n = 2; IgA multiple myeloma, n = 1; myeloproliferative disease, n = 1; and myelodysplastic syndrome, n = 1. Patients with malignancy were older (median age, 59 years), were more likely to be male (M/F = 8.5), had joint involvement more frequently (95%), and had a lower frequency of prior acute infection than those without malignancy. A typical paraneoplastic course was documented in only two cases. CONCLUSIONS: Epidemiological studies are needed to determine the association between adult HSP and malignancy. In practice, it may be wise to suspect a malignancy in men older than 40 years of age who develop HSP in the absence of a precipitating factor. Pathogenic hypotheses involve tumor antigens or abnormal IgA production leading to immune complex formation.

Spinal tuberculosis in adults. A study of 103 cases in a developed country, 1980-1994.

Spinal tuberculosis (TB) accounts for about 2% of all cases of TB. New methods of diagnosis such as magnetic resonance imaging (MRI) or percutaneous needle biopsy have emerged. Two distinct patterns of spinal TB can be identified, the classic form, called spondylodiscitis (SPD) in this article, and an increasingly common atypical form characterized by spondylitis without disk involvement (SPwD). We conducted a retrospective study of patients with spinal TB managed in the area of Paris, France, between 1980 and 1994 with the goal of defining the characteristics of spinal TB and comparing SPD to SPwD. The 103 consecutive patients included in our study had TB confirmed by bacteriologic and/or histologic studies of specimens from spinal or paraspinal lesions (93 patients) or from extraspinal skeletal lesions (10 patients). Sixty-eight percent of patients were foreign-born subjects from developing countries. None of our patients was HIV-positive. SPD accounted for 48% of cases and SPwD for 52%. Patients with SPwD were younger and more likely to be foreign-born and to have multiple skeletal TB lesions. Neurologic manifestations were observed in 50% of patients, with no differences between the SPD and SPwD groups. Of the 44 patients investigated by MRI, 6 had normal plain radiographs; MRI was consistently positive and demonstrated epidural involvement in 77% of cases. Bacteriologic and histologic yields were similar for surgical biopsy (n = 16) and for percutaneous needle aspiration and/or biopsy (n = 77). Cultures for Mycobacterium tuberculosis were positive in 83% of patients, and no strains were resistant to rifampin. Median duration of antituberculous chemotherapy was 14 months. Surgical treatment was performed in 24% of patients. There were 2 TB-related deaths. Our data suggest that SPwD may now be the most common pattern of spinal TB in foreign-born subjects in industrialized countries. The reasons for this remain to be elucidated.

Nonsurgical treatment of osteoarticular tuberculosis. A retrospective study in 143 adults.

OBJECTIVE AND METHODS: Data are sparse on nonsurgical treatments currently used for osteoarticular tuberculosis in industrialized countries. We conducted a multicenter retrospective study in the Paris urban area, France, in 206 cases of osteoarticular tuberculosis documented by examination of a local specimen. This article reports our findings in the 143 patients who were followed up at least until treatment completion. RESULTS: Mean follow-up after treatment completion was 16 months. Seventy-five (52%) patients had spondylitis and 68 (48%) did not. The number of antituberculous agents used during the initial treatment phase was four in 65% of cases and three in 35%. In the spondylitis subgroup, mean (+/- SD) antibiotic therapy duration was 14.7 +/- 3.4 months, and 25% of patients required surgery; 3% of patients died, 1% suffered a relapse, and 96% achieved a full recovery with no relapse. In the nonspondylitis subgroup, mean antibiotic therapy duration was 13 +/- 3 months and 29% of patients required surgery. The only HIV-positive patient had osteitis of the calcaneus with a relapse that led to discovery of secondary rifampin resistance. CONCLUSION: Based on our findings and on data from the literature, we believe that 12 months is a reasonable duration for antituberculous therapy in osteoarticular tuberculosis, including tuberculous spondylitis.

Hypersensitivity to glucocorticoids: does it exist?

Hypersensitivity to corticosteroids is a classical but rarely reported event. We report a 30-year-old patient who developed generalized urticaria after her first methylprednisolone bolus. We reviewed the relevant literature to look for factors associated with hypersensitivity to corticosteroids. Causality should be evaluated on a case-by-case basis using diagnostic criteria for drug hypersensitivity reaction. Etiopathogenesis may involve either an IgE-mediated immunoallergic reaction or semi-delayed hypersensitivity. The main problems are identification of the offending agent and evaluation of the safety of further corticosteroid therapy. Although a few fatal reactions have been reported, some were probably due to underlying cardiovascular disease or serum electrolyte abnormalities.
