5 years after a previous study, we followed up a group of thalassemic patients, determining DHEA-S levels in peripubertal age, with the aim of evaluating whether adrenarche maturation occurred in boys and advanced in girls. Furthermore, we evaluated the degree of bone mineral density (BMD SDS(BA)) and analyzed growth parameters calculating standard deviation score with respect to bone age (BA) of height (Ht SDS(BA)), sitting height (SH SDSBA), and subischial leg length (SLL SDSBA), body mass index (BMI) and the difference between the values of the previous and the present study (deltaBMI), thyroid function and serum markers of bone metabolism. Our results showed persistent lack of adrenarche (DHEA-S 25+/-9.5 microg/dl) in all 6 boys and the absence of pubertal signs at chronological age (CA) of 12.4+/-1.4 yr and BA of 11.1+/-1.1 yr. Only one boy, 6 months later, showed a testicular volume of 4 ml (Tanner stage G2) with an increase of DHEA-S value (181 microg/dl) at BA 12.8 yr. Body disproportion and severe degree of osteopenia (BMD SDSBA -2.41+/-0.5) were observed in all boys, even though Ht SDSBA (0.14+/-0.8) and markers of bone metabolism were within the normal range. No change in nutritional status was observed (deltaBMI 0.09+/-0.4 kg/m2). In contrast, all the thalassemic girls had DHEA-S values (172.7+/-97.7 microg/dl) within the normal range at BA 12.7 +/-0.6 yr that was similar to CA. Furthermore, the appearance of Tanner stage B2 occurred in each of them at BA, near to CA, of 10.4+/-0.9 yr, and menarche was observed in three of them at mean BA, near to CA, of 11.4+/-0.9 yr. Ht SDSBA was below normal range (-1.11+/-0.8), but SLL SDSBA and SH SDS(BA) values were reduced homogeneously, so that proportional body growth was observed. A significant change in nutritional status was observed (deltaBMI 2.69+/-0.9 kg/m2). Bone density value (BMD SDS(BA) -0.25+/-0.4) was in the normal range. There were no statistically significant differences between boys and girls for ferritin serum levels, blood consumption and desferrioxamine dosage. In conclusion, lack of change in nutritional status, measurable in the form of deltaBMI, but not BMI alone, considered an important physiological regulator of adrenarche, regardless of individual adrenal androgen secretion, could have a key role in the lack of adrenarche persisting in thalassemic boys during peripubertal age. Further follow up is necessary, in particular when boys reach puberty, because delayed adrenarche represents the most intriguing aspect in these patients.

Low-grade Nonhodgkin lymphoma (LG-NHL) is characterized by indolent clinical course, which consist of marginal zone lymphoma (MZL), follicular lymphoma (FL), chronic lymphocytic leukemia/small lymphocytic lymphoma, lymphoplasmacytic lymphoma, waldenstrom macroglobulinemia (WM) as the most common subtypes. Factors affecting prognosis and treatment need in these patients have long been the subject of research. A retrospective study was conducted with patients diagnosed with LG-NHL in Hematology Departments of two centres between 2010 and 2018. At the time of diagnosis, demographic and disease characteristics, hematological and biochemical parameters were examined. Using these data, treatment requirements, response and survival rates were calculated. The effect of parameters on survival and need to treatment were analyzed. 93 LG-NHL patients were included in this study. 40 (43%) of these patients were MZL, 28 (30.1%) were FL and 25 (26.8%) were others. In comparison of patients required treatment with patients without treatment, there was significant difference among the number of comorbidity, platelet count, neutrophil count, disease subgroups and ferritin levels. Logistic regression analysis revealed that disease subgroup (other than MZL and FL) and ferritin levels were independent risk factors for need to treatment. Only ferritin level was found to be associated with overall survival. The current study demonstrated an association between serum ferritin levels and prognosis in patients with LG-NHL. Given that it is easily available and low-cost, the initial ferritin level can be used as a prognostic marker for patients with indolent lymphoma.
