ABSTRACT
An unusual clonal gammopathy was reported in COVID-19 patient but whether this anomaly is related or not to the disease has not yet been clarified. To this aim, we selected a cohort of 35 COVID-19 patients swab positive and investigated serological levels of IL-6, immune response to major viral antigens and electrophoretic profile. Elevated levels of IL-6 were accompanied by a significative humoral response to viral Spike protein, revealing an altered electrophoretic profile in the gamma region. We can conclude that elevated levels of IL-6 triggers humoral response inducing a transient plasma cell dyscrasia in severe COVID-19 patients.

We aimed at assessing the prevalence of peripheral neuropathy in newly diagnosed, treatment-naïve patients with multiple myeloma. We enrolled 153 patients with multiple myeloma at initial diagnosis. All patients underwent neurological examination and nerve conduction study. Patients with suspected pure small fiber neuropathy underwent skin biopsy. Of the 153 patients included in this study, 7.2 % had a multiple myeloma-related neuropathy. All patients suffered from a distal symmetric sensory peripheral neuropathy, associated with age (P = 0.04). Our study on prevalence rate of multiple myeloma-related peripheral neuropathy might provide a basis for improving the clinical management of this condition.

One hundred and one depressed inpatients were treated by the authors with a second-generation antidepressive original molecule: Toloxatone, a specific and reversible MAO A inhibitor. Upon admission, all 101 patients with depressive illness did not score higher than 20 on Hamilton's Scale, and did not score lower than 4 on Fischer, Fernández Labriola and Rodríguez Casanova's Endogeneity Test. Biological profiles (Phenyl-ethylamine, NA, and MHPG) were available on 57 subjects. At the beginning of the experiment: (a) No subject was taking antidepressives, (b) Patients' age averaged 46; (c) The 6-week experiment was a double-blind vs. placebo type. Daily toloxatone dose was standardized in a 400 mg intake. Significant modifications were detected in 51 subjects. Among the 59 subjects that were administered active substance, 37 achieved either "excellent" or "good" outcomes. Biological markers pointed out a profile of patients with a better response to Toloxatone: Namely, patients with a lower noradrenergic activity. Anxiety-free depression as well as inhibited depressions are a psychiatrist's choice for administering Toloxatone.

ABSTRACT
We have investigated the possibilities of technetium-99m-(-3-aminohydroxypropylidene)-1-1-bisphosphon ate ([99mTc]APD) as a bone scanning agent in 14 normal subjects and 28 patients. Similar studies in the same normal subjects and patients were carried out with 99mTc-methylene-bisphosphonate ([99mTc]MDP). The compounds were labeled with 99mTc by means of an electrolytical method; the free pertechnetate content was always under 1%. The [99mTc]APD T1/2 of the third component of the disappearance plasma curve in six normal subjects was 152 +/- 46 min (mean +/- s.d.), while the 24-hr whole-body retention (WBR) was 17.6% +/- 4.6. The [99mTc]MDP value of the 24-hr WBR was 28.6% +/- 3.9 (p less than 0.001). The bone/soft-tissue ratio (B/ST) was investigated in eight control subjects on the eleventh thoracic and the fourth lumbar vertebrae. The B/ST ratios were similar for both APD and MDP studies. In 28 patients with suspected bone metastasis or primary bone disease, bone scintigraphy was carried out; both compounds showed similar findings and the same number of positive results. In five of these patients, the lesion/normal bone ratio was determined with values of 4.6 +/- 2.0 in APD studies and 4.8 +/- 2.3 with MDP. APD was also used in 126 patients; no adverse reactions were observed. The APD dose used i.v. for bone scanning was 200-fold less than those employed by mouth per day, for the treatment of bone disease for long periods. In our experience, APD appears to be an adequate agent for bone scintigraphy.
