The study aimed to examine leukocyte telomere length (LTL) and serum neuregulin-4 levels and their relationship with disease activity, co-morbidities and body fat distribution in female acromegaly patients. Forty female patients with acromegaly and thirty-nine age and body mass index (BMI) similar healthy female volunteers were included in the study. Patients were classified into two groups: active acromegaly (AA) and controlled acromegaly (CA). The quantitative polymerase chain reaction (PCR) method was used to study LTL, and T/S ratio < 1 was accepted as shortened telomere length. Neuregulin-4 was studied by ELISA. There was no difference in median LTL between acromegaly and the control group (p = 0.530). The percentage of T/S < 1 in patients with acromegaly (60.0%) was similar to that of the control group (43.6%) (p = 0.144). However, serum neuregulin-4 was significantly higher in patients with acromegaly than those in the control group (p = 0.037). There were no significant differences concerning LTL, percentage of T/S < 1 and neuregulin-4 levels between active and controlled acromegaly groups (p > 0.05). Neuregulin-4 correlated positively with fasting glucose, triglyceride (TG), triglyceride/glucose (TyG) index, and lean body mass in the acromegaly group. A negative correlation was observed between LTL and neuregulin-4 in the control group (p = 0.039). When the factors affecting neuregulin-4 were evaluated by multivariate linear regression analysis with an enter method, TG (β: 0.316, p = 0.025) was independently and positively associated with neuregulin-4. Our findings indicate that acromegaly is associated with unchanged LTL and high neuregulin-4 levels in female patients. However, the relationship between acromegaly, the aging process, and neuregulin-4 involves complex mechanisms, and further studies are needed.

Coronavirus disease-2019 (COVID-19) has become a serious health problem in Turkey and the world. The diagnosis stage of many chronic diseases, the treatment process and the status of being affected by COVID-19 have become the focus of attention in the medical community during the pandemic, which has been continuing for nine months. We will discuss the course of COVID-19 infection over a 32-year-old and 76-year-old female patient with Cushing syndrome who applied to our clinic as a tertiary referral centre.

Pseudogout (PG) is an inflammatory arthropathy that develops due to the accumulation of calcium pyrophosphate dihydrate crystals in synovial structures. Herein, we present a 59-year-old male patient with PG developed as a result of zoledronic acid (ZA) infusion, which was administered due to primary hyperparathyroidism. The patient with parathyroid adenoma was given ZA since the calcium level did not decrease despite intravenous saline and loop diuretic. One day after ZA administration, the patient had severe pain, fever, and swelling in joints. The radiograph showed chondrocalcinosis. Calcium pyrophosphate deposition were observed in the arthrocentesis fluid under polarized light. The patient’s symptoms regressed after anakinra and colchicine treatment. To the best of our knowledge, this is the first case report of a PG attack after ZA treatment for primary hyperparathyroidism. Additionally, there have been few cases of PG after bisphosphonate treatment for osteoporosis in the literature, signifying that more care should be taken when administering bisphosphonate therapy in patients with risk factors.
