Peripheral nervous system involvement in essential cryoglobulinemia and nephropathy.

The clinical and neurophysiological features of 23 patients affected by essential cryoglobulinemia (EC) have been studied. It was possible to perform sural nerve biopsy in 3 cases. Six patients were found to be affected by a peripheral neuropathy, according to the WHO criteria, while in 8 other patients clinical and neurophysiological signs of a milder peripheral nervous system (PNS) involvement were evident. The incidence of PNS involvement seems to be high (60.9%). Neurophysiological and histological studies were indicative of a mainly axonal damage.

Multifrequency rhythms of immunological functions.

Chrono-immunological functions are reviewed starting from the first studies on circadian variations in the count of circulating blood eosinophils to the most recent studies on lymphocyte subpopulation periodicities. Serum Ig levels, complement components, plaque forming cells, phagocytosis, autologous mixed lymphocyte reactions, have also been demonstrated to be circadian periodic. Transplant immunology is also known to show circadian and circa septan periodicities in the rejection of transplanted organs. Rhythms of susceptibility to a series of allergens and bronchial asthma symptoms characterize chronobiology in allergy. A periodic pattern is a common finding in the recurrence of the symptoms in rheumatoid arthritis. Finally, the beginnings of chrono-immunotherapy of experimental and human tumors are briefly reviewed. The conclusion that can be drawn from this short overview is that the demonstration of the periodicity in such a big number of variables in health and the modifications of the relevant parameters in disease, emphasize the importance of the predictable, since periodic, part of the variations that can be shown by the immunological findings.

Toward a chronoimmunomodulation by cefodizime in multiple myeloma and chronic uremia.

Nine healthy subjects, 19 patients with multiple myeloma (MM) and 21 patients with chronic uremia were given cefodizime (2 g i.v.) at 2 different timepoints either in the morning or in the evening for 5 to 7 consecutive days. The following immunological parameters were comparatively evaluated before and after cefodizime administration: rosette-forming cells (RFC%), T lymphocyte subpopulations, monocyte chemotaxis index (MCI) and granulocyte chemotaxis index (GCI). Independently of the time of drug administration, a circadian rhythm was clearly detected (90% CI) as regards RFC%, CD3, CD4, CD8, CD4/CD8 before and RFC%, CD3, CD4, CD8, GCI after therapy. In addition, in patients treated at 0800 cefodizime increased the MESOR of the MCI and, to a lesser extent, of the GCI. The chronoimmunomodulatory effects of cefodizime in patients with MM and chronic uremia are discussed.
