Importance of Blood Glucose Measurement for Predicting the Prognosis of Long COVID: A Retrospective Study in Japan.

Purpose: The present study aimed to clarify the effects of a hyperglycemic condition on the clinical consequences of long COVID. Methods: Among 643 patients who visited the outpatient clinic of our hospital from February 2021 to September 2023, long COVID patients were classified into a hyperglycemic (HG) group with casual blood glucose levels above 140 mg/dL and a normoglycemic (NG) group. The patients' backgrounds, clinical symptoms, health status including the QOL evaluation scale (EQ-5D-5L), self-rating depression scale (SDS), and F-scale questionnaire (FSSG), blood test data, and recovery periods were analyzed. Results: The NG group included 607 patients with long COVID and the HG group included 36 patients with long COVID. Patients in the HG group were older than those in the NG group (55 vs. 41 years; p < 0.001) and included a larger percentage of males (67% vs. 44%; p = 0.009). The HG group had a larger percentage of patients with moderate-to-severe conditions in the acute infection phase (28% vs. 12%; p = 0.008), a higher BMI (25 vs. 22 kg/m2; p < 0.001), higher blood pressure (138/81 vs. 122/72 mmHg; p < 0.001), and a larger percentage of patients with an alcohol drinking habit (53% vs. 34%; p = 0.031). Long COVID symptoms and self-rated scales were not differed between the two groups; however, the laboratory data showed that liver and renal functions and metabolic data were significantly worse in the HG group. Although there was no apparent difference between the two groups in duration from the infection to the first visit, the HG group had a significantly longer period of recovery from long COVID (median period of 421 vs. 294 days; p = 0.019). Conclusion: A hyperglycemic state associated with other lifestyle-related diseases is associated with the prolongation of recovery from long COVID.

Clinical characteristics of Campylobacter bacteremia: a multicenter retrospective study.

Campylobacter species are the pathogens of the intestinal tract, which infrequently cause bacteremia. To reveal the clinical characteristics of Campylobacter bacteremia, we performed a retrospective, multicenter study. Patients diagnosed with Campylobacter bacteremia in three general hospitals in western Japan between 2011 and 2021 were included in the study. Clinical, microbiological, and prognostic data of the patients were obtained from medical records. We stratified the cases into the gastroenteritis (GE) and fever predominant (FP) types by focusing on the presence of gastrointestinal symptoms. Thirty-nine patients (24 men and 15 women) were included, with a median age of 57 years and bimodal distribution between those in their 20 s and the elderly. The proportion of GE and FP types were 21 (53.8%) and 18 (46.2%), respectively. Comparing these two groups, there was no significant difference in patient backgrounds in terms of sex, age, and underlying diseases. Campylobacter jejuni was exclusively identified in the GE type (19 cases, 90.5%), although other species such as Campylobacter fetus and Campylobacter coli were isolated in the FP type as well. Patients with the FP type underwent intravenous antibiotic therapy more frequently (47.6% vs. 88.9%), and their treatment (median: 5 days vs. 13 days) and hospitalization (median: 7 days vs. 21 days) periods were significantly longer. None of the patients died during the hospitalization. In summary, we found that nearly half of the patients with Campylobacter bacteremia presented with fever as a predominant manifestation without gastroenteritis symptoms.

Clinical and microbiological characteristics of polymicrobial bacteremia: a retrospective, multicenter study.

PURPOSE: To clarify the clinical and microbial characteristics of polymicrobial bacteremia (PMB) to contribute to improvements in clinical diagnosis and effective early treatment. METHODS: This retrospective multicenter study used data from three acute-care hospitals in Okayama Prefecture, Japan, collected between January 2014 and March 2019. We reviewed the demographics, comorbidities, organisms isolated, infectious focus, and 30-day mortality of patients with PMB. RESULTS: Of the 7233 positive blood cultures, 808 (11.2%) were positive for more than one organism. Of the patients with bacteremia, 507 (7.0%) had PMB, of whom 65.3% were male. Infectious foci were identified in 78.3% of the cases, of which intra-abdominal infections accounted for 47.1%. A combination of Gram-positive cocci (GPC) (chain form) and Gram-negative rods (GNR) accounted for 32.9% of the cases, and GPC/GNR and GNR/GNR patterns were significantly associated with intra-abdominal infections. The 30-day mortality rate of patients with PMB was 18.1%, with a median of 7.5 days from diagnosis to death. The mortality in patients with an infectious focus identified was significantly lower than that in patients with an unknown focus (16.3% vs. 24.5%; p = 0.031). CONCLUSIONS: Intra-abdominal infections were the most common source of PMB, and were strongly associated with a Gram-staining combination pattern of GPC (chain form)/GNR. PMB cases with an unknown focus had a poorer prognosis, highlighting the importance of early diagnosis and appropriate treatment.

Clinical Characteristics of Low Androgen Status in Males with Type 2 Diabetes Mellitus.

To determine the clinical characteristics of low androgen status in adult males with diabetes, we retrospectively analyzed the medical records of patients with type 2 diabetes mellitus in whom serum free testosterone (FT) levels were examined for 1 year. Among the 46 patients (56 ± 1.5 years old), decreases in serum FT levels to < 8.5 pg/ml (indicating the occurrence of late-onset hypogonadism [LOH]) were detected in 18 (39%). The per-centages of patients with low FT levels were high in the ≥ 50 years age group (83%), the HbA1c < 7% group (67%), and the 25 ≤ BMI < 30 kg/m2 group (56%). The serum FT levels tended to decrease age-dependently. The level of HbA1c was significantly correlated with the Heinemann Aging Male Symptoms (AMS) score (R = 0.47). The low-FT group had decreased levels of hemoglobin. Of note, the serum FSH level (R = -0.32) was negatively correlated with the serum FT level, whereas the serum TSH level (R = 0.36) was positively correlated with the serum FT level. Collectively, these results revealed that many diabetic males may have low FT levels and that the AMS score is related to the HbA1c level. A slightly anemic condition, thyroid dysfunction, and obesity (class 1) might be involved in LOH in middle-aged diabetic males.

Clinical Relevance of Blood Glucose and Gastroesophageal Reflux Symptoms to Depressive Status in Patients with Type 2 Diabetes Mellitus.

A relationship between diabetes and depression is apparent. To clarify the clinical relevance of diabetic patients' gastroesophageal symptoms to their psychological status, we retrospectively analyzed the data from a Selfrating Depression Scale (SDS) and a Frequency Scale for Symptoms of Gastroesophageal reflux disease (FSSG) among 143 type 2 diabetic patients who visited a general medicine department. Among the 45 Japanese patients enrolled, the group with relatively high SDS scores (≥ 36) showed higher (FSSG) dysmotility symptom scores versus the low-SDS (< 36) group, although the 2 groups' characteristics and laboratory data were not significantly different. Positive correlations of postprandial plasma glucose (PPG) levels with FSSG scores (R=0.321, p<0.05), particularly with reflux scores (R=0.455, p<0.01) were revealed. PPG and HbA1c levels were not correlated with SDS scores. The patients' SDS scores were significantly correlated with their FSSG scores (R=0.41, p<0.01), suggesting that depressive status is linked to GERD-related manifestations. Considering that the patients' PPG levels were correlated with GERD-related symptoms, diabetic patients' blood glucose levels are associated with depressive status. Collectively, key symptoms related to GERD and glucose level values would be helpful.

Correlations between Depressive Condition and Gastroesophageal Reflux Symptoms in Patients Visiting a Department of General Medicine.

To clarify the potential relevance of patients' chief complaints at a general medicine department to their self-rating depression scale (SDS) and frequency scale for symptoms of gastroesophageal reflux disease (GERD) (FSSG) scores, we analyzed data of 478 patients who visited our general medicine department. The chief complaints (553 symptoms of 447 patients) were categorized into major symptom-based groups: respiratory (31%), circulatory (3%), gastrointestinal (GI) tract (26%), neurology (8%), orthopedic and skin (10%), and systemic (22%) symptoms. The SDS score tended to be higher in females and younger patients. The FSSG score did not differ by gender but was higher in younger patients. The patients receiving social welfare had higher SDS and FSSG scores. A close inter-relationship between the FSSG (including both degrees of reflux and dysmotility) and SDS was observed in all patients. Although the averages of the SDS and FSSG scores were not significantly different among the symptom-based categories, we observed significantly positive correlations between the FSSG and SDS in each category, suggesting that depressive status may be closely related to GERD-related symptoms regardless of the patients' chief complaints. An initial checkup of patients' psychological condition and/or GERD-like symptoms could help screen for latent disorders in outpatients with uncertain complaints.

A Patient with Type 3 Autoimmune Polyglandular Syndrome who Developed Systemic Lupus Erythematosus 8 years after the Diagnosis of Autoimmune Hepatitis.

Eight years prior to her present admission, a 61-year-old Japanese woman was diagnosed with autoimmune hepatitis, slowly progressive insulin-dependent diabetes mellitus, and chronic thyroiditis; she had been treated with oral prednisolone (PSL). After she suddenly discontinued PSL, she newly developed systemic lupus erythematosus. A combination therapy of oral PSL and intravenous cyclophosphamide resulted in remission. She was finally diagnosed with autoimmune polyglandular syndrome (APS) type 3 (3A ,3B, 3D), complicated with four different autoimmune diseases. Since patients with type 3 APS may present many manifestations over a long period of time, they should be carefully monitored.

Characteristic Clinical Features of Werner Syndrome with a Novel Compound Heterozygous WRN Mutation c.1720+1G>A Plus c.3139-1G>C.

Werner syndrome (WS) is an autosomal recessive progeroid disorder caused by mutations in the WRN gene (WRN). Most Japanese WS patients are born from a consanguineous marriage with homozygous WRN mutations. We herein report a rare WS patient born from non-consanguineous parents with compound heterozygous WRN mutations with a novel heterogeneous c.1720+1G>A substitution plus the most frequent heterogeneous c.3139-1G>C substitution among Japanese. Although the present case showed clinical characteristics common to previous Japanese WS patients, he had not developed any malignant tumors as of 43 years of age, suggesting that WS patients with this particular genetic mutation have a different phenotype than others.

A Case of Dermatomyositis with Severe Myalgia and Muscle Weakness Testing Positive for Anti-melanoma Differentiation-associated Gene 5 Antibody.

We report a case of a woman with typical dermatomyositis (DM) with skin manifestations, severe myalgia and muscle weakness complicated by interstitial lung disease (ILD) and pneumomediastinum. Pneumomediastinum persisted despite treatment with immunosuppressive therapy (steroids and cyclosporine). After the test for anti-melanoma differentiation-associated gene 5 (MDA5) antibody came out positive, we doubled the cyclosporine dose and her condition improved. Despite typical clinical features of DM, in cases complicated by pneumomediastinum or steroid resistance, measurement of anti-MDA5 antibody may be useful for immunosuppressant dose titration.
