Sixty-two patients with bronchopneumonia or bronchitis were treated with cefaclor. In 42 patients (= 68%), the therapy was clinically successful. Of the patients who did not respond to therapy, cefaclor-resistant bacteria were found in the sputum culture of seven. Of the remaining 13 patients, ten suffered a secondary infection with cefaclor-resistant bacteria, and in three patients the pathogen found before therapy persisted, although sensitive to cefaclor on testing. In seven patients therapy was clinically successful although cefaclor-resistant pathogens were present before the start of therapy. In the entire group of patients investigated no increase of SGOT, SGPT, alkaline phosphatase, bilirubin, urea or creatinine was observed. In two patients alkaline phosphatase and SGOT increased slightly; in three patients SGPT increased slightly. On the other hand, in several patients initially elevated SGOT, SGPT and alkaline phosphatase activity decreased during therapy. Clinical side-effects were seen in two patients. In one patient with known penicillin allergy a pruritic exanthema developed; in the other patient, who had dermatitis herpetiformis, exacerbation of skin efflorescences occurred.

From the papules of a patient with massive cutaneous hyalinosis, we earlier isolated a mannose-rich glycoprotein that, by immunohistochemical methods, was also shown to be present in epithelial cells of small intestine and normal skin. A solid-phase enzyme immunoassay of IgG and IgM antibodies to this epithelial glycoprotein is described, in which polystyrene tubes are coated with the purified antigen. The antibodies are allowed to bind, and are detected with alkaline phosphatase-conjugated anti-human IgG and IgM. IgG, IgA and IgM antibodies were determined in the sera of patients with pemphigus, pemphigoid, dermatitis herpetiformis, several autoimmune diseases, in a patient with massive cutaneous hyalinosis, in coeliac disease, and in control subjects. Very high values were found in the patient with massive cutaneous hyalinosis, and significantly elevated values in coeliac disease. In the other patient groups values were equal to or only slightly higher than in controls.

Of 228 patients with adult coeliac disease, 42 (19%) were diagnosed aged 60 years or over. In this series, of 35 patients who did not have dermatitis herpetiformis, 15 had attended family doctors and hospital outpatient departments for an average of 28 years with unexplained symptoms or abnormalities in blood tests but the diagnosis of coeliac disease had been missed. This is unsatisfactory because these patients can both manage and respond to a gluten free diet. Thirty eight patients complied strictly with the diet with resolution of symptoms. Significant improvement in weight, haemoglobin, albumin, calcium, and alkaline phosphatase values after a year on the diet also occurred. Clinicians should be alert to the possibility of coeliac disease in the elderly particularly in patients with non-specific complaints in the presence of unexplained anaemia.

Dermatitis herpetiformis (DH) is a chronic subepidermal blistering disease, in which a perivascular cellular infiltrate, composed mainly of CD4+ T lymphocytes together with a varying number of neutrophils and eosinophils, is thought to be important in the pathogenesis of blister formation. The aim of this study was to investigate the potential role of cytokines such as the interleukins IL-4 and IL-5 and to quantify the distribution of T cells as well as their state of activation using alkaline phosphatase-antialkaline phosphatase and reverse transcriptase-polymerase chain reaction (RT-PCR) procedures in seven patients with typical clinical and histological features of DH. A strong extracellular staining with anti-IL-4 monoclonal antibody was detected in the upper dermis with a prevalent perivascular pattern in perilesional areas, whereas in the dermal-epidermal separation sites there was an intense, scattered distribution. IL-5 was intensely expressed, mainly at the intracellular level, by eosinophils and lymphocytes. Concerning RT-PCR, five DH patients showed a strong positive signal for both IL-4 and IL-5 cytokines while two patients showed a faint signal for both IL-4 and IL-5; these last two cases were histologically poor in inflammatory cells. In view of these results, it can be hypothesized that the recruitment of eosinophils and neutrophils in DH may be induced not only by granulocyte macrophage colony-stimulating factor and IL-8 as previously demonstrated, but also by Th2 cytokines as well.

Cutaneous eruptions related to hepatitis C virus (HCV), a major cause of hepatitis in the setting of blood transfusion, intravenous drug abuse, organ transplantation, and hemodialysis, are typically reported as isolated cases. We encountered 35 cases of HCV infection associated with cutaneous eruptions. The present study evaluates paraffin-embedded, formalin-fixed tissue sections stained with hematoxylin and eosin from biopsy specimens of skin lesions from 35 patients seropositive for HCV. In 20 cases, reverse transcriptase polymerase chain reaction (RT-PCR) was performed using a probe for HCV RNA; the RNA was detected through the action of alkaline phosphatase on the chromogen nitroblue tetrazolium and bromochloroindolyl phosphate. The clinical spectrum comprised dermatomyositis-like photodistributed eruptions, palpable purpura, folliculitis, violaceous and perniotic acral lesions, ulcers, nodules, and urticaria. Lesions were also classified histopathologically by the dominant reaction pattern: vasculopathies of neutrophilic, lymphocytic, and granulomatous vasculitis and pauci-inflammatory subtypes (15 patients); palisading granulomatous inflammation (3 patients); sterile neutrophilic folliculitis (5 patients); dermatitis herpetiformis (1 patient); lobular panniculitis composed of neutrophilic lobular panniculitis in 2 patients and benign cutaneous polyarteritis nodosa in 1 patient; neutrophilic dermatoses, including neutrophilic urticaria, neutrophilic eccrine hidradenitis, and pyoderma gangrenosum (3 patients); interface dermatitis (3 patients); and low-grade lymphoproliferative disease of B-cell lineage representing marginal zone lymphoma in 1 patient and a clonal plasmacellular infiltrate in another patient. In most cases, whereas 1 of the aforementioned disorders defined the dominant reaction pattern, there was an accompanying secondary reaction pattern, defining a hybrid picture. Endothelial changes including endothelial cell enlargement and effaced heterochromatin with margination of the chromatin to the nuclear membrane were seen in several cases; in some cases similar cytopathic changes also involved the supporting pericytes, eccrine ductular cells, or keratinocytes. The RT-PCR analyses in 8 of 20 cases examined revealed HCV RNA expression in a focal, weak fashion in endothelia and perivascular inflammatory cells in those cases showing vasculopathic changes. Viral parasitism of endothelia may be important in cutaneous lesional propagation in the setting of HCV infection. Cross-reactivity between endogenous and viral antigens, leading to cellular and/or type II immune reactions; viral tropism to B lymphocytes, resulting in B cell expansion with resultant autoantibody production; and circulating immune complexes containing monoclonal cryoglobulins may also be of pathogenetic importance. Tropism of the virus to B lymphocytes provides a mechanism for the development of low-grade clonal B cell lymphoproliferative disease in this setting.
