Associations Between Low Serum Testosterone and All-Cause Mortality and Infection-Related Hospitalization in Male Hemodialysis Patients: A Prospective Cohort Study
Infectious diseases are the second highest cause of death in patients on dialysis. In addition, testosterone deficiency or hypogonadism is prevalent in dialysis patients. However, to our knowledge, no studies have investigated the association between testosterone levels and infectious events. We aimed to evaluate whether serum testosterone levels are associated with infection-related hospitalization in male hemodialysis patients in a prospective cohort study.
Methods: We divided the study population into 3 groups based on serum testosterone levels. Associations between testosterone levels and clinical outcomes of infection-related hospitalization, all-cause mortality, and cardiovascular disease (CVD) events were analyzed using the Cox proportional hazard model.
Results: Nine hundred two male patients were enrolled and followed up for a median of 24.7 months. Their mean ± SD age was 63.4 ± 11.8 years, and their median (interquartile range) of total testosterone was 11.7 nmol/l (7.9–14.9 nmol/l). During follow-up, 123 participants died. Infection-related hospitalization and CVD events occurred in 116 and 151 patients, respectively. Infection-related hospitalization was more frequent in the lower testosterone tertile than in the higher testosterone tertile (hazard ratio [HR]: 2.12; 95% confidence interval [CI]: 1.18–3.79; P = 0.01) in adjusted models. Moreover, all-cause mortality was significantly greater in the lower testosterone tertile than in the higher testosterone tertile in adjusted analysis (HR: 2.26; 95% CI: 1.21–4.23; P = 0.01). In contrast, there were no significant differences in CVD events by testosterone level.
Discussion: Low levels of testosterone may be associated with higher rates of infection-related hospitalization and all-cause mortality in male hemodialysis patients
A case of pulmonary hyalinizing granuloma characterized by pseudohyponatremia due to hyperproteinemia
A 57-year-old man presented with multiple pulmonary nodules. Thoracoscopic lung biopsy led to a pathological diagnosis of pulmonary hyalinizing granuloma (PHG) at the age of 39 years. The disease was progressive, refractory to therapy, and necessitated home oxygen therapy 10 years after the diagnosis. Hyponatremia progressed gradually along with lung disease. His serum sodium level was 129 mEq/L but serum osmolality was normal (287 mOsm/kg). Concomitant hyperproteinemia (12.1 g/dL) was attributable to hyperglobulinemia. Direct ion-selective electrode measurement revealed a normal sodium level (137 mmol/L). We herein report a case of PHG characterized by pseudohyponatremia due to hyperproteinemia, an uncommon finding in this rare entity. A left lung transplant was successfully performed, and no pseudohyponatremia was observed. Pseudohyponatremia should be suspected and diagnosed to prevent a misdiagnosis that could lead to complications from inappropriate treatment with sodium supplementation or restriction of drinking water. The direct ion-selective electrode measurement was useful for diagnosing pseudohyponatremia
