Summary
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can impair pituitary–gonadal axis and a higher prevalence of hypogonadism in post-coronavirus disease 2019 (COVID-19) patients compared with the general population has been highlighted. Here we report the first case of a patient affected with a long-COVID syndrome leading to hypogonadism and treated with testosterone replacement therapy (TRT) and its effects on clinical and quality of life (QoL) outcomes. We encountered a 62-year-old man who had been diagnosed with hypogonadotropic hypogonadism about 2 months after recovery from COVID-19 underwent a complete physical examination, general and hormonal blood tests, and self-reported questionnaires administration before and after starting TRT. Following the TRT, both serum testosterone level and hypogonadism-related symptoms were improved, but poor effects occurred on general and neuropsychiatric symptoms and QoL. Therefore, hypogonadism does not appear to be the cause of neurocognitive symptoms, but rather a part of the long-COVID syndrome; as a consequence, starting TRT can improve the hypogonadism-related symptoms without clear benefits on general clinical condition and QoL, which are probably related to the long-COVID itself. Longer follow-up might clarify whether post-COVID hypogonadism is a transient condition that can revert as the patient recovers from long-COVID syndrome.
Learning points
-
Hypogonadism is more prevalent in post-COVID-19 patients compared with the general population.
-
In these patients, hypogonadism may be part of long-COVID syndrome, and it is still unclear whether it is a transient condition or a permanent impairment of gonadal function.
-
Testosterone replacement therapy has positive effects on hypogonadism-related clinic without clear benefits on general symptomatology and quality of life, which are more likely related to the long-COVID itself.

Summary
Diabetes foot ulcer (DFU) is a common long-term complication of diabetes. Intractable chronic wounds to standard care of diabetic foot raise the question of whether other factors intervene in disease development. We report a case of a 54-year-old male patient who came to Sardjito General Hospital with leg pain and previous history of multiple debridement and amputation for DFU referred from a remote hospital yet no improvement was evident in the surrounding lesion following treatment. Consequently, a histopathological examination was carried out proving the presence of other aetiologic factors, vasculitis and panniculitis existing in the lesion. In this case, we report a rare type of causative factor of foot ulcers among diabetic patients. Vasculitis suspected for polyarteritis nodosa accompanied by panniculitis is considered in this patient. The treatment of choice is corticosteroids or immunosuppressants based on the clinical condition, contrary to usual wound care in DFU. Based on the evidence, clinicians need to consider other causes than only macrovascular complications in a diabetic patient with DFU that is intractable to standard wound care. In this patient, vasculitis may be considered in forming diabetic foot ulcers alongside macrovascular complications.
Learning points
-
A thorough examination is essential to rule out other processes in intractable DFU patients.
-
Prompt management based on proper diagnosis is crucial to prevent peripheral arterial disease complications.
-
Vasculitis and macrovascular complication are inseparable processes forming DFU in this patient.

Summary
Calciphylaxis is a rare disorder characterised by the development of painful necrotic skin lesions. Occlusion of cutaneous arterioles due to ectopic calcification leads to potentially life-threatening widespread skin loss. Most cases occur in patients with chronic renal disease, which leads to dysregulation of calcium and phosphate homeostasis. Only a handful of case reports exist describing calciphylaxis occurring in patients without chronic renal disease but with hypoparathyroidism. We report on a unique case of a 53-year-old man with multiple endocrine neoplasia type 1 syndrome and acquired hypoparathyroidism due to total parathyroidectomy who went on to develop calciphylaxis following cardiac surgery.
Learning points
-
Calciphylaxis most commonly occurs in the context of chronic renal disease but can rarely occur in its absence as a consequence of calcium and phosphate dysregulation.
-
Patients who develop necrotic skin lesions in the presence of hypoparathyroidism require an urgent dermatological opinion.
-
Mortality from calciphylaxis is high, with the majority of deaths occurring secondary to sepsis.
-
Management of calciphylaxis requires a multidisciplinary team approach to manage wound healing, infections and pain.
-
Recovery with full rehabilitation from calciphylaxis can take months to years.

Summary
IgG4-related disease is a multiorgan disorder in which nodules and hypertrophic lesions are observed simultaneously, or separately, in areas including the pancreas, liver, lungs, salivary glands, thyroid glands, and pituitary glands. IgG4-related hypophysis is one of several IgG4-related diseases and is characterized by pituitary gland and pituitary stalk thickening, various degrees of hypopituitarism, and increased serum IgG4 levels. Steroid therapy is effective for patients with IgG4-related hypophysis, but the reported effectiveness of steroid therapy for restoring pituitary function differs between studies. Following an episode of autoimmune pancreatitis 10 years prior, enlargement of the pituitary gland and stalk along with panhypopituitarism and polyuria developed in a 73-year-old male. A high serum IgG4 level and biopsy of the submandibular gland showing infiltration of IgG4-positive plasma cells led to a clinical diagnosis of IgG4-related hypophysitis. Prednisolone treatment reduced the swelling of the pituitary gland and stalk and improved anterior pituitary function. Although arginine vasopressin secretion remained insufficient, polyuria was relieved and kept in remission even after prednisolone treatment was completed. This is the first reported case in which prednisolone was able to maintain both normal anterior pituitary function and remission of polyuria caused by IgG4-related hypophysitis. IgG4-related hypophysitis has previously been associated with a relapse of symptoms during treatment. However, the patient reported in this case study remained in remission for over 3 months after completion of steroid treatment and should be monitored closely for changes in pituitary function.
Learning points
-
Steroid therapy is the first-line therapy for pituitary dysfunction and pituitary stalk swelling in IgG4-related hypophysitis.
-
In this case, although posterior pituitary function remained insufficient, polyuria was relieved and kept in remission for over 3 months even after prednisolone treatment was completed.
-
IgG4-related hypophysitis has been associated with the relapse of symptoms during steroid tapering, and changes in pituitary function and symptoms should be monitored closely.
-
When we encounter cases of adrenal insufficiency and polyuria during observation of autoimmune pancreatitis or other IgG4-related disease, we should consider the possibility of IgG4-related hypophysitis in mind.

Summary
Symptoms of primary adrenal insufficiency (PAI) are commonly nonspecific, causing the disease to be misdiagnosed or often delayed, and patients may present to the hospital with a life-threatening crisis. Previous case reports have documented that patients in this condition often require lifelong glucocorticoid replacement therapy. This study aimed to present a noteworthy outcome of PAI caused by adrenal tuberculosis infection, demonstrating complete recovery after six months of glucocorticoid replacement therapy. A 38-year-old Indonesian man presented to the endocrinology clinic in a tertiary hospital with a chief complaint of epigastric pain. The patient experienced nausea, vomiting, loss of consciousness, weight loss, excessive sweat, decreased appetite, weakness, and dizziness in the past 2 weeks. Laboratory examinations revealed hyponatremia, elevated adrenocorticotropic hormone, and suppressed morning plasma cortisol level. A non-contrast-enhanced abdominal MRI showed unilateral right-side adrenal enlargement and calcification. The patient’s Mantoux test was positive. Corticosteroids and anti-tuberculosis therapy were administered. After 6 months, hydrocortisone was discontinued due to the patient’s good clinical condition and normal morning plasma cortisol levels. After a 1-year follow-up, the patient remained asymptomatic with normal cortisol levels. We hypothesized several reasons for this unique outcome: (i) the patient was relatively young compared to previous cases, suggesting an adequate immune system may play a role; (ii) despite a 1-month delay in diagnosis and treatment, the absence of skin hyperpigmentation suggested an acute presentation, potentially contributing to the favorable outcome; and (iii) the absence of comorbidities potentially positively impacted the patient's outcome.
Learning points
-
Symptoms of adrenal insufficiency are often nonspecific and may only become apparent once significant damage has occurred to the adrenal gland.
-
Clinical adjustments and a comprehensive understanding of epidemiological knowledge are necessary for diagnosing patients with endocrine diseases in limited-resource settings.
-
Complete recovery in primary adrenal insufficiency caused by tuberculosis infection might be due to younger age, acute presentation, and absence of comorbidities

Summary
A 20-year-old South Asian male presented with polyuria, polydipsia, HbA1c 81 mmol/mol, BMI 28.8 and family history of both type 1 and type 2 diabetes mellitus. As autoantibody testing was negative and c-peptide level demonstrated significant endogenous insulin secretion, type 1 diabetes was excluded. Given his age and family history, the differential diagnosis included maturity-onset diabetes of the young (MODY), a rare form of diabetes caused by a single-gene variant. A high probability of MODY was calculated and he was subsequently referred for genetic testing. Although a useful tool, the pre-test probability calculator for MODY is only validated in White Europeans. A heterogenous variant of unknown clinical significance of the NEUROD1 gene was detected, leading to gliclazide use with poor response. The patient responded well to metformin. Type 2 diabetes was considered the most likely diagnosis. This case highlights the diagnostic challenges in young patients of Asian ethnicity and the importance of interpreting genetic results of unknown significance within the clinical context. Ethnicity-specific BMI thresholds should be used when classifying patients as overweight or obese.
Learning points
-
Variants of unknown significance detected by genetic sequencing should be interpreted within the context of the patient’s other clinical parameters.
-
It is important to use ethnicity-specific BMI thresholds for obesity.
-
Diagnosis of type 2 diabetes mellitus at younger ages is becoming increasingly common.
-
The pre-test probability calculator for MODY is only validated in White Europeans; although a useful guide, results should be interpreted with caution in patients of other ethnicities.

Summary
Mitotane is used for treatment of advanced adrenocortical carcinoma. It is administered when the carcinoma is unresectable, metastasized, or at high-risk of recurrence after resection. In addition, mitotane is considered to have direct adrenolytic effects. Because of its narrow therapeutic–toxic range, therapeutic drug monitoring (TDM) is warranted. In 2020, a left-sided adrenal gland tumor was found (5.8 cm) in a 38-year-old man. Considering the size of this lesion and inability to exclude an adrenocortical carcinoma on imaging, a laparoscopic adrenalectomy was performed. Histopathologic examination determined presence of an adrenocortical carcinoma (pT2N0M0 ENSAT stadium II; ki67 10–15%). There was no evidence for residual or metastatic disease but given the high risk of recurrence, adjuvant therapy with mitotane was initiated. During TDM, a sudden and spuriously high level of mitotane was observed but without signs or symptoms of toxicity. After exploration, it was found that this high concentration was completely due to uncontrolled hypertriglyceridemia. After correction thereof, mitotane levels were again in the therapeutic range. This observation underscores the importance of TDM sampling in a fasting state with concurrent control of prevalent or incident dyslipidemia.
Learning points
-
TDM of mitotane is advocated to achieve therapeutic levels while avoiding toxicity. For correct TDM, sampling should be done at least 12 h after last intake of mitotane.
-
Although sampling in fasting conditions in not explicitly mentioned in the guidelines, fasting state should be considered as elevated serum triglyceride levels might cause spuriously high mitotane levels.
-
In patients undergoing treatment with mitotane and presenting with too high or unexplained fluctuating mitotane levels without signs or symptoms of toxicity, hypertriglyceridemia as a possible cause should be investigated.
-
If dyslipidemia occurs in patients under mitotane treatment, other causes than mitotane (e.g. alcohol abuse and diabetes) should be considered and appropriate treatment should be initiated.

Summary
In patients with diabetes mellitus, the toxic milieu caused by abnormal glucose and free fatty acid handling can lead to heart failure (HF). Referred to as diabetic cardiomyopathy (DMCM), this syndrome often exists in the absence of conventional risk factors for HF such as history of myocardial infarction or hypertension. Low-carbohydrate diets (LCDs) have recently been endorsed as an efficacious therapeutic dietary approach to prevent and reverse cardiometabolic disease including type 2 diabetes mellitus (T2DM). LCDs improve systemic insulin resistance (IR), reverses cardiac remodelling in a rodent model and downregulates the expression of sodium–glucose co-transporter 2 (SGLT2) receptors in the kidney. It is therefore conceivable that a lifestyle approach such as adopting an LCD can be offered to patients with DMCM. The reported case is that of a 45-year-old man with a 15-year history of non-ischaemic cardiomyopathy, T2DM and obesity. The patient volunteered to engage in a 16-week low-carbohydrate dietary intervention trial and then self-selected to remain on this diet for 1 year. The whole-food LCD was based on simple ‘traffic light’ style food lists and not designed to restrict calories, protein, fat or salt. After 1 year, the patient had lost 39 kg and his cardiometabolic markers had significantly improved. LCDs present a potentially beneficial approach for patients with DMCM and could be considered as a lifestyle intervention before SGLT2i therapy is commenced.
Learning points
-
Diabetic cardiomyopathy (DMCM) is a syndrome precipitated mainly by the detrimental effects of glucose metabolism disorders such as insulin resistance and diabetes.
-
Low-carbohydrate diets (LCD) mimic many effects of sodium–glucose co-transporter 2 inhibitors (SGLT2i).
-
LCDs are a dietary pattern which can have significant and beneficial effects on metabolic and anthropometric markers in patients with DMCM.
-
LCDs and SGLT2i therapy could be combined and may achieve better clinical outcomes for patients with DMCM.
-
Combination therapy may be carried out under close supervision as the real risk for diabetic ketoacidosis remains.

Summary
Type 1 diabetes mellitus (T1DM) is an autoimmune disorder caused by the destruction of the pancreatic beta cells, which produce insulin. Individuals with T1DM usually require at least 3-5 years to develop microvascular complications in comparison to people with type 2 diabetes (T2DM), who may develop complications even before the diagnosis of diabetes. We discuss a patient who presented with proliferative diabetic retinopathy subsequently diagnosed with T1DM and diabetic neuropathy following investigations. Diabetic retinopathy or other microvascular complications as the presenting feature of T1DM is rarely known or reported in the literature. A 33-year-old healthcare worker had been seen by the opticians due to 1-week history of blurred vision. The ophthalmology assessment had confirmed proliferative retinopathy in the right eye and severe non-proliferative retinopathy in the left eye with bilateral clinically significant macular oedema. His BMI was 24.9 kg/m2. The nervous system examination revealed bilateral stocking type peripheral neuropathy. The random venous glucose was 24.9 mmol/L. Plasma ketones were 0.7 mmol/L and HbA1c was 137 mmol/mol. On further evaluation, the anti-glutamic acid decarboxylase (GAD) antibody was positive, confirming the diagnosis of T1DM. He was started on aflibercept injections in both eyes, followed by panretinal photocoagulation. Subsequent nerve conduction studies confirmed the presence of symmetrical polyneuropathy. The pathogenesis of the development of microvascular complications in T1DM is multifactorial. Usually, the development of complications is seen at least a few years following the diagnosis. The occurrence of microvascular complications at presentation is rare. This makes the management challenging and extremely important in preventing the progression of the disease.

Summary
We report a 61-year-old male patient without personal history of thyroid carcinoma or radiation exposure. In 2011, he presented with a cervical mass whose biopsy diagnosed a papillary thyroid carcinoma (PTC) in a lymph node metastasis (LNM). Total thyroidectomy with lymphadenectomy of central and ipsilateral compartment was performed. Histopathology identified a 2 mm follicular variant of PTC and LNM in 25/25 lymph nodes. The patient was treated with 150 mCi of radioactive iodine (RAI), followed by levothyroxine suppressive therapy. In 2016, a retrotracheal mass was diagnosed, suggesting local recurrence; patient was submitted to surgical excision and RAI therapy (120 mCi). Due to seizures, in 2019, a brain CT was performed that diagnosed brain metastases. The patient underwent debulking of the main lesion. Histopathology analysis confirmed a metastatic lesion with variated morphology: classical PTC and follicular pattern and hobnail and tall cell features. Molecular analysis revealed BRAFV600E in LNM at presentation and BRAFV600E and TERT promoter (TERTp) mutations in the recurrent LNM and brain metastasis. Based upon this experience we review the reported cases of subcentimetric PTC with brain metastases and discuss the molecular progression of the present case.
Learning points
-
Papillary microcarcinoma (PMCs) usually have very good prognosis with low impact on patient survival.
-
PMCs presenting in elderly patients with LNM at diagnosis may carry a guarded outcome.
-
Brain metastasis although rare indicate aggressive phenotypic features.
-
Patient risk stratification of PMCs based on histopathological analysis and genetic testing may have a significant impact on prognosis providing therapeutic markers, that may predict disease progression and overall outcome.
